The EDI Committee have proposed this Union Symposium to reflect on themes arising from the screening of The Leadership documentary NET1.
In particular, we are interested in exposing and exploring the power of networks, how they are created and how networks can help researchers progress in their professional careers. This US will encourage you to reflect at a personal level on your own network, assess whether it is optimised for success, and provide clues on how you can better construct and interact in your network to optimize opportunities and garner valuable support during your often challenging career path.
Secondly, this US will provide an opportunity to raise awareness and stimulate a conversation about how we as a geoscience community augment and reinforce networks that will inspire and retain underrepresented members of the geoscience community thus bringing their voices into the 'rooms' where decisions on science and policy amongst other societal issues are currently taking place.
Public information:
Moderator Lisa Wingate 15:10-15:15 Introduction to the topic of the US.
Our first speaker will be Dr Madeleine Hann 15:15-15:25 Physically present in Vienna
Dr Madeleine Hann will talk about her motivation and experience for joining the Homeward Bound network and travelling to Antarctica with a shipful of future leaders.
Our second speaker will be Daria Ludtke 15:25-15:35 Physically present in Vienna
Dr Daria Ludtke is the Western European ambassador for the network Women+ In Geospatial https://womeningeospatial.org/. Daria will introduce this bottom-up network, its history, how it works and how it has evolved and adapted to the needs of the growing geospatial community.
Our third speaker Prof Christine Cross 15:35-15:45 Virtually present over Zoom
Prof Christine Cross will intorduce us to a recently EU-funded COST Action called VOICES https://gendervoices.eu/ that aims to explore and develop tools to assist early career researchers develop leadership, mentoring and networking skills.
Christine will provide information on this COST Action and provide insights on how to use the COST Action programme to develop tools, networks and promote a shift in the diversity of leaders stepping into positions that can impact society.
Our final speaker will be Laura Lots from the SNSF 15:45-15:55 Virtually present over Zoom
Laura Lots will present the AcademiaNet https://www.academia-net.org/ database and network. With this presentation we aim to raise awareness of this initiative in the geoscience community to increase the number of institutes enrolling diverse STEM and geoscience researchers to appear in this database, in addition to advertising the utility of this database for finding diverse voices to participate on conference symposia, project proposals, funding panels to represent geosciences within the EU. It can also help the EGU society give recognition to the work and achievements of our diverse community members. No more excuses!

The biodiversity of the planet is inextricably tied to the future of humanity. Our impacts on, and ability to find solutions to, the alarmingly accelerating loss of species may not only define their survival but our own future too.
Biodiversity encompasses the variety of living organisms on Earth, including their habitats and their interactions. It supports our food system, increases community resilience, and underpins global GDP. Biodiversity is both vital for and impacted by agriculture, freshwater ecosystems, biogeosystems, soil health, climate change, natural hazards, and pollution. Despite the undeniable importance of biodiversity on environmental and societal wellbeing, ecosystems are being damaged and disappearing at an ever-faster rate.
Preserving and restoring biodiversity are incredibly complex tasks that will require both scientific expertise and intersectoral collaboration. This Union Symposium will highlight some of the key biodiversity challenges that humanity is currently facing and how they can potentially be overcome. It will also outline some of the recent European biodiversity targets and legislation, what’s coming next, how geoscience is being used to find solutions, and where more research is needed.
The Symposia panel will include geoscientists working in areas related to the biodiversity and policymakers who are currently working on European biodiversity initiatives and who are concerned by integrative pathways to be explored with water, climate, soil, oceans, natural hazards, biogeosystems, and Earth observations. The session will include presentations from these speakers as well as a moderated discussion on how geoscientists can best support the Europe’s biodiversity targets and a Q&A with the audience. While this session will have a European focus, it will also emphasise the importance of biodiversity as a global issue.

The format of scientific conferences has come under significant scrutiny and has been the subject of extensive debate in recent years; these debates centered on the carbon footprint and sustainability of such conferences, but also on questions of Equality, Diversity and Inclusion as well as accessibility at these conferences. Within the geosciences, the debate has been particularly strong given that global change and sustainability are part of our direct research subjects and the community has realized the amount of work still needed to attain the goal of truly inclusive and diverse meeting participation and a fair and equal exposure at such conferences.
The Covid-19 pandemic has strongly expedited the evolution of scientific conferences, as numerous learned societies were forced to organize virtual meetings. EGU has thus needed to very rapidly change the format of the 2020 General Assembly from a traditional in-person meeting to “Sharing Geoscience online”, and organize vEGU21 as a fully virtual meeting, while EGU22 is the first hybrid meeting in the history of the Union.
It is now a good time to take stock and look forward: what have we learned from our experiences with virtual and hybrid meetings; how can we take these experiences to design more sustainable global meetings in future; how can we make such hybrid meetings more accessible and inclusive while fostering diversity of presenters and ideas? This Union Symposium will bring together meeting organizers and members of the community who have presented thoughts about future meetings to reflect on the required and desired evolution of scientific conferences, with a focus on the geosciences.

“Neo-colonial science” or “parachute science” is a practice where international scientists, usually from higher-income countries, conduct fieldwork or collect data and samples in another country, usually of lower income, and then elaborate the data and publish scientific results without involving native researchers and/or communities.
This Union Symposium will provide participants with an introduction to the neo-colonial science, highlighting pertinent examples on how this practice has created a dependency on expertise with consequent lack of knowledge building and infrastructures development in countries that have been the base of important discoveries. Neo-colonial science is particularly evident across many geosciences’ disciplines, where low income countries have been used as natural laboratories for fieldwork of world-class researchers.
Scientific neocolonialism is unfair to the local scientific communities, who may contribute to the work without being recognized nor treated as equal partners. In addition, the scientific interpretations resulting from such approaches may suffer from the lack of local knowledge – which could prevent wrong hypothesis or extrapolations.
The presentations and discussions of this Union Symposium aim to shed light on various examples of scientific neo-colonialism, how EGU members can have significant impact, and how inclusion in global research can lead to better science.

Over the past few years, criticism on the singularly focused metrics evaluation of scientists has grown, making it clear that a cultural shift is needed to modernise our assessment system. Many universities and funding agencies worldwide have already signed the San Francisco Declaration of Research Assessment (DORA), thereby committing to a broader and more overarching assessment of researchers and their research proposals.
For the last several decades, quantitative indices such as the number of publications, the h-index or the journal impact factor have served as near-singular measures of scientific success. Other key areas, such as education, leadership, and institutional and societal engagement have been undervalued. While being a good educator, having strong leadership skills and serving the scientific community are appreciated, these parameters have become a requirement in addition to an impressive publication record. This means scientists need to excel in all academic activities (research, teaching, service) in order to be considered successful, which places unrealistic expectations on individuals and significantly increases their workload.
By allowing for more diversity in academic career paths and a broader definition of what constitutes scientific excellence, there would be more options for honoring and nurturing individual talents and motivations. This could lead to a more balanced academic system that is better equipped to tackle today’s scientific challenges, including a stronger focus on team performance. Many opponents of a revised assessment system, however, fear that moving away from quantitative measures will make it more difficult to objectively assess and compare academics, leading to a loss of quality. Qualitative characterizations are more difficult to compare and rely on the make-up of the evaluating team, but that is not reason to dismiss them as part of the evaluation process.
In this great debate, we query: (1) Is there a mechanism to integrate qualitative assessment with quantitative metrics when evaluating academics, (2) how could a revised assessment system be organised and implemented universally, as adoption by all is needed for it to be effective, and (3) how will broader assessment criteria strengthen scientific leadership in the future?
The IPCC’s sixth assessment report could not be clearer that climate change is both extreme and accelerating, that human activity is unequivocally to blame, that the impacts will be severe, and that we must act swiftly and dramatically, both collectively and as individuals.
As earth scientists, our community will have a vital role to play in assessing impacts, informing actions and helping to shape both public understanding, and political action.
This Great Debate examines the role of the earth science community at this pivotal moment for human society and the overall health of our planet.
An invited panel representing a broad cross-section of scientists, policy-makers and influencers will address the following questions:
• What is the role for earth scientists in solving the greatest challenge humanity has ever faced?
• Do we have the skills, the agility and the resources we need?
• Are we creating the science and information we need, and are we doing it fast enough?
• Are our academic and research institutions fit for purpose, and focused on the right challenges?
• Do we have the necessary communications skills and channels, and the confidence to deliver sometimes difficult messaging with clarity and impact?
• Can we strengthen evidential links between continued harmful activities and impacts, and will we be ready to demonstrate the benefits of positive actions?
• Can our messaging help tip societal values and behaviour towards positive action?
To quote UN Secretary General António Guterres, ‘The alarm bells are deafening (and) there is no time for delay and no room for excuses.’

Open Science represents research that is collaborative, transparent, and accessible. This includes providing open access to all scientific outputs, such as publications, data, methods, software, and more. Open Science practices are intended to improve transparency, reproducibility, and dissemination of new knowledge. By enabling greater usability of data and methods, it has the potential to improve the productivity of the research community.
Despite best intentions by the scientific community, several barriers often prevent making data, software, and publications fully open and accessible to all. For example, sharing of data may be constrained by confidentiality issues or protective data policies by private and public organisations. Furthermore, storing and sharing large datasets comes with technical challenges and costs that may be difficult to face for individuals and organisations. Similarly, sharing methods and software in a format accessible to others may require additional effort, for instance the application of software engineering best practices, that researchers may be reluctant to undertake due to lack of adequate reward, incentives, or recognition. The drive towards Open Science may also be met with reticence or resistance by individuals or organisations that are currently well-served by the status quo.
In this Great Debate we invite our panel members and the audience from all geosciences to reflect on the following questions:
* How can universities, funding bodies, and publishers promote Open Science?
* What more can structural initiatives such as Plan S or DORA do to support Open Science?
* What are some successful examples and barriers yet to be overcome?
* How can researchers and administration help remove those barriers?
* Are individual researchers primarily responsible for advancing Open Science, or should institutions, publishers and funding agencies take main responsibility?
* How can we align the goals of individual researchers (i.e. careers/publishing) and the scientific community (i.e. gaining knowledge but also avoiding duplication of efforts)?
* What are the priorities to bring Open Science into practice (e.g. open access to articles, data, code, workflows)?
* How does commitment to Open Science impact science-industry collaborations and translation of science into practice?
* What are pitfalls in Open Science? Are there disadvantages?

Data is at the backbone of our research discussions, conclusions and solutions to problems nature presents us with. Did the apple fall to the ground, once or twice? It always does.
In today’s age with use of the most advanced laboratory capability the (geo)science community produces data at an ever increasing level of precision, resolution and volume. E.g. 1000 geochronology dates a day using laser ablation ICP mass spectrometry systems at a 30 µm resolution with <5% precision, that is <1Gb. Large Hadron Collider (LHC) detectors generate about one petabyte of collision data per second (~1Mb per collision). Most of this analytical data is highly variable and lacking standardised community-agreed metadata.
The greatest challenge pertaining to laboratory analytical research is to collate, store and make these data publicly available in standardised and machine-accessible form. But do we have to? Do we want to?
This great debate puts the questions, problems, challenges and opportunities around geoanalytical research data to the center stage at EGU, a topic researchers from almost every scientific division are concerned with. Short opening statements, from a panel representing the Earth, Environmental, Planetary and Space sciences, are followed with a discussion on how to improve the situation for EGU members who work with and on laboratory analytical data.
Discussions can be around:
Community development of systems to facilitate easy and efficient research data management, and need for more user buy-in.
The push from publishers and journals who increasingly require access to the supporting data from a trusted repository prior to publication of manuscripts.
When should data, initially collected in a researcher’s private domain, become public?
The need for and lack of global standards, best practices and protocols for analytical data management and exchange in order for scientists to better share their data in a global network of distributed databases.
When to capture analytical data, raw (lab), reduced (private/collaborative), polished (publicised).
To ensure long-term impact of these data, they need to be efficiently managed and losslessly transferred from laboratory instruments in “Private” domains to a “Collaboration” domain, to the “Public” domain, complete with all relevant information about the analytical process and uncertainty, and cross-references to originating samples and publications.

The journey of water on planet Earth is long and timeless. The study of the water cycle, hydrology, is a broad field of geosciences as water travels from the atmosphere to the deep soil and from rivers to oceans. Hydrology includes a diverse range of observations, theories, models and predictions for the coupled human-natural systems. Fundamental & applied research in hydrology has direct implications for the monitoring, modelling & management of water in glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands, and aquifers. Central to the climate-environment-society interactions, hydrology offers invaluable knowledge & tools for informing policy-relevant decisions as well as driving sustainable climate resilience & disaster preparedness for compound & multiple hazards.
Despite being traditionally rooted in engineering, research progress in hydrology has lately benefited from the perspective shift towards Earth System (ES) Science. The IAHS Unsolved Problems in Hydrology (UPH) highlights the need for improved research collaboration across diverse systems, scales & processes of geosciences. The efforts of the World Meteorological Organization in developing a research strategy for hydrology is rooted in bringing hydrology forward in the implementation of weather & climate research programs for seamless ES prediction. However, translation of research into delivery of national hydrological & meteorological services remains low and ineffective. This is ever more needed as the Earth’s disturbed hydrological cycle manifests more frequent & intense weather-water-climate extremes with far reaching consequences for the safety of citizens & economies.
In this Great Debate, we bring the following questions forward to catalyze the future evolution of hydrology in support of integrated (geo)science-practice-policy-education development: * What are geoscientists missing about the water cycle? * What is the role of hydrology in modelling the dynamic interactions & feedbacks of the different ES components? * Are we doing enough to represent coupled social–economic–natural complex ecosystems hydrologically right in ES models? * Do we need higher resolution/more accurate hydrological models or better linkages to society/policy? * How can improved (hydrological) process knowledge make its way to hydromet services & water policy? * Can hydrology provide ESS the critical leverage to foster impact-based services, citizen engagement & environmental policy agendas?

A lack of permanent positions and predominantly temporary contracts in academia is challenging for early and mid-career scientists. Recent estimates in Germany suggest that 78% of scientists are on fixed-term contracts (German Trade Union Confederation, 2020). Their life is heavily impacted by job options which in turn also influences their future career choices. Often, the initial idea behind fixed-term contracts was to enhance scientific exchange, collaborations, and innovation. However, many scientists experience the disadvantages associated with them, such as regularly moving city/country, uprooting families, and regular pressure to find a new job. Many scientists attribute short-term contracts to their desire to move away from academic careers. The distribution of fixed-term and permanent contracts is not equal across gender, ethnicity, or age. Whilst recent studies in the U.K. found 28% of white male scientists were employed on a fixed-term basis, this number was 45% for Asian female scientists (Higher Education Statistics Agency, U.K., 2019). Would science benefit from more permanent contracts? Or do short-term contracts provide opportunities to work with a range of groups and institutes?
Recently, there has been a surge in the discussion on fixed-term contracts and the academic careers system in general. In this panel discussion (if the GA is online) or round-table discussion (if the GA is in-person), invited speakers will share their opinions and provide suggestions on how to move forward or revise the career system. This debate will give the opportunity to discuss a timely and controversial topic that is relevant for all career stages.

An increasing number of publications report that many people working in academia experience mental health issues. Factors like job insecurity, limited amount of time, expectations, poor management and dealing with papers or proposal rejections often cause high stress levels and can lead to mental health problems, such as depression, anxiety or emotional exhaustion. Following the EGU blog series and short course ‘Mind your Head’ in 2019-2021, and the successful ECS Great Debate at the General Assembly in 2019, we aim to continue the dialogue and reduce the stigma surrounding mental illness.
In this short course, we would like to focus on the causes, consequences and provide some coping tools. We invite panelists to share their professional or personal experience. Afterwards we aim to actively engage the audience to discuss how to take control of their mental wellbeing and prioritise it in the current academic environment. We invite people from all career stages and disciplines to come and join us for this short course.

After the PhD, a new challenge begins: finding a position where you can continue your research or a
job outside academia where you can apply your advanced skills. This task is not
always easy, and frequently a general overview of the available positions is missing. Furthermore,
in some divisions, up to 70% of PhD graduates will go into work outside of academia. There are many
different careers which require or benefit from a research background. But often, students and
early career scientists struggle to make the transition due to reduced support and networking.
In this panel discussion, scientists with a range of backgrounds give their advice on where to find
jobs, how to transition between academia and industry and what are the pros and cons of a career
inside and outside of academia.
In the final section of the short course, a Q+A will provide the audience with a chance to ask
their questions to the panel. This panel discussion is aimed at early career scientists but anyone
with an interest in a change of career will find it useful. An extension of this short course will
run in the networking and early career scientist lounge, for further in-depth or
one-on-one questions with panel members.

Finding funds can be challenging in academia, be it during PhD, or after that. A great proposal or just a great idea does not guarantee success, instead, it involves developing skills and exploring the paths which can lead to securing funds. It involves meticulous steps of evolving idea, proposal development, budget generation, and finally finding funding opportunities. In this course, early-career scientists, and faculty members with a wide range of backgrounds will provide guidance both in the research, and financial aspects of the proposal writing. The course is integrated with open Q&A which will provide participants to ask and seek advice from the experts. This course targets a wide range of audience ranging from graduate students to early-career scientists, but anyone with an interest in finding funds could participate

Sexual and racial harassment and other hostile behaviors, including bullying and other forms of discrimination and incivilities, have wide-ranging detrimental effects on mental and physical wellbeing, including anxiety, depression, and physiological responses akin to trauma, and can result in decreased motivation and work productivity. The tolerance of hostile behaviors can affect the community beyond the individual or individuals being targeted, and create negative work environments in entire research groups and departments. Traditional hierarchical structures within academia that create strong power imbalances allow for the potential for abuse in research and educational environments. Despite this, scientists often do not receive mentoring or training in how to address, respond to, and prevent these types of behaviors. Questions including “What behaviors are appropriate at work?”, “How do we create a work environment where people of different age, gender and sexual identity, culture, religion, ethnic origin and social class feel respected and included?” and “What can I do personally against bullying and sexual harassment at work?” are important topics that are not discussed enough in academia. Promoting conversations about these topics and identifying ways to prevent unwanted behavior are important steps towards building respectful and productive work environments.
This interactive short course explores academic practices and institutional structures that allow for harassment and other hostile behaviors to persist, discusses initiatives to address harassment as scientific misconduct, and provides training in personal intervention strategies to protect and support targets of harassment through real world scenarios. As a result of this session, participants will be able to identify:
(1) Different ways in which harassment can manifest in research environments;
(2) Strategies for bystander intervention, and
(3) Resources for cultural change in the office, laboratory, at conferences and in field settings.
This workshop was developed by ADVANCEGeo (serc.carleton.edu/advancegeo) with a U.S. National Science Foundation ADVANCE Partnership award in collaboration with the Earth Science Women's Network, the Association for Women Geoscientists and the American Geophysical Union. We welcome participants from a diverse background of Geosciences, career stages and countries.
Networking is crucial for scientists of all career stages for collaborations as well as for their personal growth and career pathways. Your scientific network can support you when struggling with everyday academic life, help with making career choices and give feedback on job applications/proposals/papers. Further, having a scientific network can provide new perspectives for your research while leading to interdisciplinary collaborations and new projects.
Building up an initial network can be challenging, especially outside of your research institution. As scientific conferences and social media platforms are evolving, the possibilities of academic networking are also changing. In this short course we will share tips and tricks on how to build, grow and maintain your scientific network. Additionally, panelist will talk about their own personal experiences. In a second part of the short course we will do a networking exercise. This short course is relevant to scientist who are starting to build/grow their network or want to learn more about networking in today’s scientific settings.

Careers in academia exist beyond research and publications. There are always aspects more than what meets the eye. Often, we tend to learn about what is made available and evident, leaving behind many questions. It is only natural for aspiring scientists to have questions that shape their minds and impact their research. Some questions pertain to professional realms, others may relate to more broader perspectives on ambitions, inspirations, and what one deems as meaningful. Not every day do we get the opportunity to present these floating concerns at a forum and have experts address and pay heed to the same. In this session, a successful scientist with many years of experience will provide a look back to give a personal perspective of her/his career.
This year, we have the absolute pleasure of having with us Professor Ellen Wohl, who is a fluvial geomorphologist and a professor of geology with the Warner College of Natural Resources at Colorado State University. Ellen’s research work focuses primarily on physical processes acting along river corridors, including physical-biotic interactions. Besides her research expertise, we shall engage in conversations regarding the challenges that came her way, and the manner in which she overcame those, and how her research shaped her life and in turn, how her life is impacted by the research she does. The discussions shall offer a unique opportunity to learn and empathise with a scholar’s work and life that has inspired many. The session shall conclude with the prospect of questions that Ellen shall be happy to answer.

The modern scientist has to operate in the Research-Services-Policy nexus to create real-world impact. The challenge is daunting and the opportunities are endless. What is truly the role of a scientist? What is your current position in this nexus? Where would you like to be in the future?
By sharing and discussing how our work is related to hydrological research, services and policy we can gain insight into how we, as a community, are positioned within this nexus. From there, we can identify opportunities and challenges associated with moving into new areas where we want to contribute, both personally and institutionally.
In this synergistic session, we will first use online interactive tools to explore where we, personally and as a group, fit within the Research-Services-Policy nexus. In the second part, we will have roundtable discussions on the visual outcomes of the first activity.
The objectives of this short course are to:
- create awareness of the several roles we can play as hydrologists,
connect over the challenges that come with balancing these different roles and sharing insights,
- identify topics / subjects / actors / issues and potential interlinks between hydrological research, services, and policy,
- and define a group perspective on the issues central in the proposed great debate “Hydrology and Earth System Science: research, services or policy?”
We embrace the “hybrid GA concept” by offering interactive activities using online platforms (survey, mind mapping and art tools) to promote engagement in the discussion regardless of participants’ locations and modes of attendance.
Anyone interested in the sciences, services and policy-making is encouraged to participate. A healthy mix and diversity of participants will greatly improve the experience for all involved.
This is a complementary event to the proposed Great Debate “Hydrology and Earth System Science: research, services or policy?”, and is organised in cooperation with the Young Hydrologic Society (http://younghs.com/).

One of the fundamental drivers of scientific progress is research integration and synthesis, which is essentially beneficial for developing research vision. Hence, literature reviews prove to be highly useful to many researchers at all academic stages. Analysing the literature and writing reviews for a thesis, article or project proposal can be sometimes challenging to fresh early career scientists. For a review paper even greater attention must be given to the methodological approach to conduct a reproducible and thorough review of the existing scientific literature.
In this short course participants will be given an overview of (literature) review types and learn about existing guidelines for conducting reviews. They will be introduced to available R packages for literature search and conducting systematic reviews. The course will also cover some insights from an editor’s perspective with helpful tips on how to write a review paper.
This session is organized in cooperation with the Young Hydrologic Society (http://younghs.com/).

Never has it been more important that geoscience research feeds into political decisions and policymaking. What is more, today many policymakers and institutions are increasingly receptive to scientific evidence. Yet, whilst researchers are increasingly keen to influence policy and policymaking, for many the mechanisms for engagement and impact seem unclear and inaccessible.
This course will demystify policymaking and give researchers the tools to be able to engage with policy through their research.
In this Short Course, participants will learn about how national and supranational parliaments use evidence in their policy shaping processes, including legislation, scrutiny and debating. They will learn about how legislative science advice or technology assessment mechanisms draw on research evidence to provide advice to parliaments – and how they can get involved. The course will be presented by experts working with the UK Parliamentary Office of Science and Technology (POST), the Austrian Institute of Technology Assessment (ITA) and the European Parliament’s Science and Technology Options Assessment panel (STOA).
Researchers will have the opportunity to ask questions and develop their skills in writing for a policy audience with the support of the course leaders.

Science is a key component of the policymaking process as it allows decision-makers to consider the evidence and potential consequences of any action or inaction. The growing complexity of societal challenges, and the policies needed to deal with them, also means that more frequent and consistent interactions between scientists and policymakers is needed.
While individual scientists can (and definitely should) engage in formal and informal policymaking processes, it’s often more effective and efficient for institutions to communicate scientific information and to be available for follow-up questions when needed. Furthermore, by engaging with the policymaking process, institutions are both supporting evidence-informed decision-making and promoting the research of their scientists and potentially increasing its impact.
Knowing exactly when or how to engage with policymaking as a scientific institution can, however, be extremely challenging. It can be daunting for a scientific organisation of any size to select a policy area to focus on, gather enough information to understand who the relevant stakeholders are, and know what information is most relevant and how to best communicate it!
This Short Course will feature the European Commission Joint Research Centre's recently launched Science for Policy Competence Framework for researchers. This Framework outlines the different competencies that research organisations need to effectively contribute to the science-policy interface. It unpacks the collective set of skills, knowledge, and attitudes desired at four different proficiency levels. It’s hoped that organisations can use this framework to see where their strengths and skill gaps are!
On 9 August 2021, the Intergovernmental Panel on Climate Change (IPCC) released the first volume of its 6th Assessment Report (AR6). The Working Group I contribution to the Report (Climate Change 2021: The Physical Science Basis) synthesises over 14,000 publications and represents the most comprehensive and up-to-date assessment of the climate system and climate change. Crucially, the Report highlights the unprecedented and potentially irreversible influence of anthropogenic climate forcing, and for the first time, explicitly states that human influence on the climate system is unequivocal.
This short course will be a panel discussion where authors and contributors of Working Group I unpack how the IPCC 6th Assessment Report (AR6) is produced, provide personal behind-the-scenes insight on its development, and discuss its global impact, including how it is used to inform policy. Authors of the report will share their experiences of working on the report before and through the COVID pandemic. Panelists will also emphasise various ways in which scientists of all career stages can contribute to the IPCC process. Ample time will be allocated for open discussion for the audience to ask related questions to the panelists.
For more information about the AR6 please visit the IPCC website: https://www.ipcc.ch/.
Communication of research has been of increasing importance during the last years. Within this necessity to presentation and outreach, the graphical representation of concepts, processes and outcomes gains more and more popularity. Scientific posters can therefore be a great opportunity to extract major findings and present them in a condensed and overviewing way. But not only the research presented follows sound theories and methods. For appealing and easily understandable presentation, the process of creating a scientific poster should consider concepts, rules and theories on how to present information as well.
In the short course of the EGU 2021, we approached the design of a scientific poster with defining the main problem, ideating to find a solution for this problem, identifying the target groups and only afterwards creating a prototype digitally. This year, we focus on the principles used in graphic design, including amongst others hierarchy, balance and white space. They represent the fundamental rules which must be considered to create an effective and attractive composition and will – especially in science - decide whether or not the message can be delivered to the audience. The aim of this course is to go through the design principles, to understand them and give suggestions on how to apply them consciously in the future.
As last year, all you need is curiosity when it comes to visual communication of your research and the willingness to discuss the topic with other participants of the course.
Visualisation of scientific data is an integral part of scientific understanding and communication. Scientists have to make decisions about the most effective way to communicate their results everyday. How do we best visualise the data to understand it ourselves? How do we best visualise our results to communicate with others? Common pitfalls can be overcrowding, overcomplicated plot types or inaccessible color schemes. Scientists may also get overwhelmed by the graphics requirements of different publishers, for presentations, posters etc. This short course is designed to help scientists improve their data visualization skills in a way that the research outputs would be more accessible within their own scientific community and reach a wider audience.
Topics discussed include:
- Choosing a plot type – keeping it simple
- Color schemes – which ones to use or not to use
- Creativity vs simplicity – finding the right balance
- Producing your figures – software and tools
- Figure files – publication ready resolutions
This course is organized by the Young Hydrologic Society (YHS), enabling networking and skill enhancement of early career researchers worldwide. Our goal is to help you make your figures more accessible by a wider audience, informative and beautiful. If you feel your graphs are complicated or not intuitive, we welcome you to join this short course.

This may be the first time you are presenting at a big international meeting. Or the 37th. You want to do a good job – to promote your work, to get that postdoc position, to secure an invited talk at the next conference. And the experts in the field will be there, those whose papers you read and whom you admire or want to impress. You do not want to waste their time. But you are nervous – heart pounding, knees shaking, red spots all over your face, hands sweaty and trembling – and to make things even worse, all the other people in your session give splendid talks. It is your turn next, you will have to get up and walk to the podium (will your legs carry you?), you will have to give your talk (will your voice be ok?), and you will have to answer questions (what if you cannot answer, or do not understand them?). Applause. You have no idea what the person just talked about. But considering the applause it must have been great. Your talk will be a mess. The convener is calling your name. Can you do it?
This course deals with what scientists normally do not talk about – giving presentations, often in a foreign language, is scary and stressful. We have all been there. We will share strategies how to deal with it. And we will provide a platform for the questions you did not dare ask your supervisor.

The work of scientists does not end with publishing their results in peer-reviewed journals and presenting them at specialized conferences. In fact, one could argue that the work of a scientist only starts at this point: outreach. What does outreach mean? Very simply, it means to engage with the wider (non-scientific) public about science. There are many ways to do outreach, including blogging and vlogging, using social media, writing for a science dissemination journal, participating as a speaker at local science festivals, organising open days in the laboratory, and so on.
With this short course, we aim to give practical examples of different outreach activities, how to start an outreach project and tips and suggestions from personal and peers’ experiences. Specific attention will be paid to science communication issues, including the proper ‘translation’ of the jargon of science into language the public understands, the selection of the content being conveyed, and the best format in which it is presented according to the different targets (policymakers, the general public, school-age children, etc.).
In the last part of the course, you will work singularly to come up with an outreach idea based on your research. You may use it on your next proposal; you never know!

Poetry can be a very effective tool in communicating science to a broader audience, and can even help to enhance the long-term retention of scientific content. During this session, we will discuss how poetry can be used to make your science more accessible to the world, including to your colleagues, your family, your friends, and other publics.
We aim to maximise empowerment and minimise intimidation, and in this fully interactive session, participants will have the opportunity to work on poems that help to communicate their research, and will be provided with feedback and advice on how to make them more effective, engaging and empathetic.

Publishing your research in a peer reviewed journal is essential for a career in research. All EGU-affiliated journals are fully open access which is great, but the unique open discussion and transparent peer review process can be daunting for first time submitters and early career scientists. This short course will cover all you need to know about the publication process from start to end for EGU journals, and give you a chance to ask the editors some questions. This includes: what the editor looks for in your submitted paper, how to deal with corrections or rejections, and how best to communicate with your reviewers and editors for a smooth transition from submission to publication. Ample time will be reserved for open discussion for the audience to ask questions to the editors, and for the editors to suggest ‘top tips’ for successful publication. This course is aimed at early-career researchers who are about to step into the publication process, and those who are yet to publish in EGU journals. Similarly, this course will be of interest to those looking to get involved in the peer-review process through reviewing and editing. This short course is part of the “Meet the EGU Journal Editors” webinar series that was held prior to the EGU General Assembly 2022.
Public information:
We are excited to welcome our panelists for this session, who will be representing their respective journals:
Meet editors of internationally renowned journals in geo- and biogeoscience and gain exclusive insights into the publishing process. After a short introduction into some basics, we will start exploring various facets of academic publishing with short talks given by the editors on
- What are the duties and roles of editors, authors and reviewers?
- How to choose a suitable journal for your manuscript and what is important for early career authors?
- How can early career scientists get involved in successful peer-reviewing?
- What is important for appropriate peer-reviewing?
- What are ethical aspects and responsibilities of publishing?
Together with the audience and the editors, we will have an open discussion of the key steps and factors shaping the publication process of a manuscript. This short course aims to provide early career scientists across several EGU divisions (e.g. AS, BG, CL, GM, NH, SSP and SSS) the opportunity of using first hand answers of experienced editors of international journals to successfully publish their manuscripts and get aware of the potentials and pitfalls in academic publishing.

Knowledge sharing in academia has been considered indispensable and is becoming a priority in most European funding schemes. Although we are already quite familiar with the different possibilities to publish our results in open-access journals, open science means way more than that. Open science aims at opening up research processes and granting access to research outputs to researchers, professionals and amateur scientists. There are different ways to ensure the storage and reusability of our data, making it available to other scientists. Furthermore, most of the scientific disciplines migrate their analyses to open-source environments (e.g., R, Phyton). However, tons of code produced remain stored in our personal computers either because we do not know the appropriate tools to share them with our colleagues or because we believe that it is not well structured.
In this short course, you would learn how to establish links between publications, data, software and methods. Hence, we will discuss with our experts: i) the options to share our data and code with other peers, ii) obtain some tips to better organize our scripts, and iii) uncover potential barriers to sharing research and discuss possible solutions.

Can the methods for symbolic depictions and navigation of physical elements be adapted to subjective, intangible matters? In this session, we will discuss a relationship between the sense of direction and navigating through thoughts and memories. Wouldn't it be nice to have a navigation system to clarify "where are we" and "where are we going" within the existential framework? Attendees will have the opportunity to create their piece of an abstract landscape from paper. No previous art experience is needed, just a will for creativity.

Rationale
The proper and deep education on ethical issues in geosciences has been evolving in recent times, although not as quickly and deeply as necessary. Many of the professionals dedicated to Earth Sciences have been not in touch with such new concepts and tendencies. Geoethics is the research and reflection on the values that underpin appropriate behaviors and practices, wherever human activities interact with the Earth system. It provides a framework to define ethical professional behaviors in Earth sciences and engineering and to determine how these should be put into practice for the benefit of environment and society. The Short Course is directed towards introducing and training Earth scientists in those new concepts and ideas as well as exposing the perspectives of this field. Social-ecological Systems and the anthropic impact on land, ocean, and atmosphere are at the cores issues to be discussed under the umbrella of geoethics, as a tool to cope with Climate Changes and other earth-society related challenges.
Completing this course, participants
1. Will know the basic principles of ethics and how these lead to geoethics
2. Will be aware of the dilemmas involved in making geoethical decisions
3. Will have gained some experience in taking a geoethical approach to real world cases
Course Content: (provisional):
1. From Ethics to geoethics: definition, values, tools
2. Responsible conduct of research and professionalism
3. Tools for confronting (geo)ethical dilemmas
4. Geoethics for society: sustainable development and responsible mining
5. Geoethics in natural hazards
6. Education challenges in geoethics
7. Geoethics in geoscience communication
8. Recent developments in geoethical thinking
9. Perspectives of geoethics
10. Geoethics’ case studies: Water Management, Ocean Governance, etc.

Research, especially for early career scientists (ECS), starts with the spark of an idea and is then often challenged by empirical or methodological road bumps and seemingly dead ends. In Earth Science research, we face a diverse range of challenges, including (1) access difficulties, whether for field sites, equipment or data, (2) problems of temporal and spatial scaling and extrapolation and (3) a lack of methods, theory or knowledge or (4) every day live challenges as a scientist. As part of SC4 we want to address some of those 'problems'. In the discussion of these challenges we seek to find possible solutions, suggest new research approaches and methods, and encourage further networking amongst early career scientists at future international conferences.
We will start the session at this year's hybrid meeting with 2 minute ‘pop-up’ presentations outlining some challenges. These pop-ups are followed by chaired and structured outbreak group discussions. There will be the option to join these discussions both in-person and virtually. To wrap up the session, solutions and suggestions from each group are presented to the whole session in a final discussion. This short course lives by your input, so participants are expected to actively engage to crowd solve the presented challenges. To ensure that people are able to have a safe and open space to share their ideas, we ask you to join for the whole session. You can get an idea of past crowd-solving sessions, both in-person and online, from our 2019 (EGU blog) and 2021 (EGU blog) blog posts, see links below.
If you have a 'problem' you would like to discuss in the networking session with us, please send a short statement (3-4 sentences) of your idea or challenge and your motivation for solving it to us, by March 1st, 2022. We expect a non-hierarchic, respectful and constructive environment for the discussions, which will hopefully encourage the participants to identify and approach problems faced by early-career scientists.
This 105-minute short course aims to introduce non-geologists to structural and petrological geological principles, which are used by geologists to understand system earth.
The data available to geologists is often minimal, incomplete and representative for only part of the geological history. Besides learning field techniques to acquire and measure data, geologists need to develop a logical way of thinking to close gaps in the data to understand the system. There is a difference in the reality observed from field observation and the final geological model that tells the story.
In this course we briefly introduce the following subjects:
1) Grounding rocks: Introduction to the principles of geology.
2) Collecting rocks: The how, what, and pitfalls of field data acquisition.
3) Failing rocks: From structural field data to (paleo-)stress analysis.
4) Dating rocks: Absolute and relative dating of rocks using petrology and geochronology methods.
5) Shaping rocks: The morphology of landscapes as tectonic constraints
6) Crossing rocks over: How geology benefits from seismology, geodynamic and geodesy research, and vice-versa.
7) Q&A!
Our aim is not to make you the next specialist in geology, but we would rather try and make you aware of the challenges a geologist faces when they go out into the field. Additionally, the quality of data and the methods used nowadays are addressed to give other earth scientists a feel for the capabilities and limits of geological research. This course is given by Early Career Scientist geologists and geoscientists and forms a quartet with the short courses on ‘Geodynamics 101 (A&B)’, ‘Seismology 101’, and ‘Geodesy 101’. For this reason, we will also explain what kind of information we expect from the fields of seismology, geodynamics and geodesy, and we hope to receive some feedback in what kind of information you could use from our side.

What is the “Potsdam Gravity Potato”? What is a reference frame and why is it necessary to know in which reference frame GNSS velocities are provided? Geodetic data, like GNSS data or gravity data, are used in many geoscientific disciplines, such as hydrology, glaciology, geodynamics, oceanography and seismology. This course aims to give an introduction into geodetic datasets and presents what is necessary to consider when using such data. This 105-minute short course is part of the quartet of introductory 101 courses on Geodynamics 101, Geology 101 and Seismology 101.
The short course Geodesy 101 will introduce basic geodetic concepts within the areas of GNSS and gravity data analysis. In particular, we will talk about:
- GNSS data analysis
- Reference frames
- Gravity data analysis
We will also show short examples of data handling and processing using open-source software tools. Participants are not required to bring a laptop or have any previous knowledge of geodetic data analysis.
Our aim is to give you more background information on what geodetic data can tell us and what not. You won’t be a Geodesist by the end of the short course, but we hope that you are able to have gained more knowledge about the limitations as well as advantages of geodetic data. The course is run by early career scientists from the Geodesy division, and is aimed for all attendees (ECS and non-ECS) from all divisions who are using geodetic data frequently or are just interested to know what geodesists work on on a daily basis. We hope to have a lively discussion during the short course and we are also looking forward to feedback by non-geodesists on what they need to know when they use geodetic data.

How do seismologists detect earthquakes? How do we locate them? Is seismology only about earthquakes? Seismology has been integrated into a wide variety of geo-disciplines to complement many fields such as tectonics, geology, geodynamics, volcanology, hydrology, glaciology and planetology. This 90-minute course is part of the Solid Earth 101 short course series together with ‘Geodynamics 101’ and ‘Geology 101’ to better illustrate the link between these fields.
In ‘Seismology 101’, we will introduce the basic concepts and methods in seismology. In previous years, this course was given as “Seismology for non-seismologists”, and it is still aimed at those not familiar with seismology -- particularly early-career scientists. An overview will be given on various methods and processing techniques applicable to investigate surface processes, near-surface geological structures, and the Earth’s interior. The course will highlight the role that advanced seismological techniques can play in the co-interpretation of results from other fields. The topics will include:
- the basics of seismology, including the detection and location of earthquakes
- understanding and interpreting those enigmatic “beachballs”
- an introduction to free seismo-live.org tutorials and other useful tools
- how seismic methods are used to learn about the Earth, such as imaging the Earth’s interior (on all scales), deciphering tectonics, monitoring volcanoes, landslides and glaciers, etc...
We likely won’t turn you in the next Charles Richter in 90 minutes but would like to make you aware of how seismology can help you with your research. The intention is to discuss each topic in a non-technical manner, emphasizing their strengths and potential shortcomings. This course will help non-seismologists better understand seismic results and facilitate more enriched discussion between different scientific disciplines. The short course is organised by early-career scientist seismologists and geoscientists who will present examples from their own research experience and high-impact reference studies for illustration. Questions from the audience on the topics covered will be highly encouraged.

The main goal of this short course is to provide an introduction into the basic concepts of numerical modelling of solid Earth processes in the Earth’s crust and mantle in a non-technical manner. We discuss the building blocks of a numerical code and how to set up a model to study geodynamic problems. Emphasis is put on best practices and their implementations including code verification, model validation, internal consistency checks, and software and data management.
The short course introduces the following topics:
(1) The physical model, including the conservation and constitutive equations
(2) The numerical model, including numerical methods, discretisation, and kinematical descriptions
(3) Code verification, including benchmarking
(4) Model design, including modelling philosophies
(5) Model validation and subsequent analysis
(6) Communication of modelling results and effective software, data, and resource management
Armed with the knowledge of a typical numerical modelling workflow, participants will be better able to critically assess geodynamic numerical modelling papers and know how to start with numerical modelling.
This short course is run by early career geodynamicists. It is aimed at everyone who is interested in, but not necessarily experienced with, geodynamic numerical models; in particular early career scientists (BSc, MSc, PhD students and postdocs) and people who are new to the field of geodynamic modelling.

This short course aims to address potential problems in geoscientific studies and to reduce the number of non-reproducible studies.
A. Fundamental issues in design of experiments and statistical analyses
The following fundamental issues will be addressed
• Time spent for experimental designs. Advantages and disadvantages of selected experimental designs. Missing randomization. Observational study vs. controlled experiments
• Pseudo-replication vs. true replications and how to deal with it. Wrong model formulations
• “Obsession” with p values: Statistical significance and geoscientific relevance
• Statistical tests: conditions for the application of modelling and hypothesis testing
• Dealing with suspected outliers
• Logistic vs. linear regression
• Number of experimental treatments vs. power of tests. Number of replicates required for predictive modelling
• Use and misuse of correlation analyses
• Investigating and dealing with interactions between factors or predictors
B. Selected additional issues in geoscientific studies
In some studies, improvements may be possible and the following fields will be addressed.
• Dealing with variance heterogeneity
• Use of contrasts instead of multiple mean testing
• Use of mixed regression and anova models
• Including squared and cubic contributions in models instead of solely relying on linear contributions. Lack of fit
• Box Cox transformation
• Validation or cross-validation instead of a sole focus on calibration.
• Model types
Examples will be shown using the software R

Observations and measurements of geophysical systems and dynamical phenomena are obtained as time series or spatio-temporal data whose dynamics usually manifests a nonlinear multiscale (in terms of time and space) behavior. During the past decades, nonlinear approaches in geosciences have rapidly developed to gain novel insights on weather and climate dynamics, fluid dynamics, on turbulence and stochastic behaviors, on the development of chaos in dynamical systems, and on concepts of networks, nowadays frequently employed in geosciences.
In this short course, we will offer a broad overview of the development and application of nonlinear concepts across the geosciences in terms of recent successful applications from various fields, ranging from climate to near-Earth space physics. The focus will be on a comparison between different methods to investigate various aspects of both known and unknown physical processes, moving from past accomplishments to future challenges.

Age models are applied in paleoclimatological, paleogeographic and geomorphologic studies to understand the timing of climatic and environmental change. Multiple independent geochronological dating methods are available to generate robust age models. For example, different kinds of radio isotopic dating, magneto-, bio-, cyclostratigraphy and sedimentological relationships along stratigraphic successions or in different landscape contexts. The integration of these different kinds of geochronological information often poses challenges.
Age-depth or chronological landscape models are the ultimate result of the integration of different geochronological techniques and range from linear interpolation to more complex Bayesian techniques. Invited speakers will share their experience in several modelling concepts and their application in a range of Quaternary paleoenvironmental and geomorphologic records. The Short Course will provide an overview of age models and the problems one encounters in climate science and geomorphology. Case studies and practical examples are given to present solutions for these challenges. It will prepare the participants from CL, GM and other divisions for independent application of suitable age-depth models to their climate or geomorphologic data.

The climate is highly variable over wide ranges of scale in both space and time so that the amplitude of changes systematically depends on the scale of observations. As a consequence, climate variations recorded in time series or spatial distributions, which are produced through modelling or empirical analyses are inextricably linked to their space-time scales and is a significant part of the uncertainties in the proxy approaches. Rather than treating the variability as a limitation to our knowledge, as a distraction from mechanistic explanations and theories, in this course the variability is treated as an important, fundamental aspect of the climate dynamics that must be understood and modelled in its own right. Long considered as no more than an uninteresting spectral “background”, modern data shows that in fact it contains most of the variance.
We review techniques that make it possible to systematically analyse and model the variability of instrumental and proxy data, the inferred climate variables and the outputs of GCM’s. These analyses enable us to cover wide ranges of scale in both space and in time - and jointly in space-time - without trivializing the links between the measurements, proxies and the state variables (temperature, precipitation etc.). They promise to systematically allow us to compare model outputs with data, to understand the climate processes from small to large and from fast to slow. Specific tools that will be covered include spectral analysis, scaling fluctuation analysis, wavelets, fractals, multifractals, and stochastic modeling; we discuss corresponding software. We also include new developments in the Fractional Energy Balance Equation approach that combines energy and scale symmetries.

Over the last decades, research in the Solar–Terrestrial sciences has greatly advanced our understanding of this huge and complex system. For half a century, satellites and a continuously growing network of ground-based observatories have allowed us to make observations in more remote regions of the Sun–Earth system and with higher precision than ever before. Besides, high-performance computing has enabled the development of powerful numerical models, which give us an unprecedented insight into each level of solar-terrestrial couplings. As new space missions and breakthroughs in numerical simulations fill in today’s missing pieces of knowledge, new questions arise, that need to be tackled by new thoughts. Being an early-career scientist, it is often hard to identify which questions are new and what has been answered before. In this short course, we have invited a panel of renowned researchers. They will give their view on how far we have come in our understanding, and most importantly, on what open questions and challenges lie ahead for the young scientists to embark upon. This is an excellent opportunity to meet with the experts and discuss the future of our community. The target audience is students and early-career scientists who want to increase their awareness of current and future research challenges within solar–terrestrial sciences and to discuss their potential contributions.
Public information:
This short course will consist of three visionary talks, given by Assoc. Prof. Manuela Temmer (University of Graz), Prof. Xochitl Blanco-Cano (Universidad Nacional Autónoma de México) and Prof. Ondrej Santolik (Institute of Atmospheric Physics of the Czech Academy of Sciences).
After the three talks, there will be time for questions, to which the three Experts will answer as a panel. Both on-site and online participants are strongly encouraged to ask their questions!

The climate system as a whole can be viewed as a highly complex thermal/heat engine, in which numerous processes continuously interact to transform heat into work and vice-versa. As any physical system, the climate system obeys the basic laws of thermodynamics, and we may therefore expect the tools of non-equilibrium thermodynamics to be particularly useful in describing and synthesising its properties. The main aim of this short course will be twofold. Part 1 will provide an advanced introduction to the fundamentals of equilibrium and non-equilibrium thermodynamics, irreversible processes and energetics of multicomponent stratified fluids. Part 2 will illustrate the usefulness of this viewpoint to summarize the main features of the climate system in terms of thermodynamic cycles, as well as a diagnostic tool to constrain the behavior of climate models. Although the aim is for this to be a self-contained module, some basic knowledge of the subject would be beneficial to the participants.
- The first part, chaired by Remi Tailleux, will provide an advanced introduction on the fundamentals of equilibrium and non-equilibrium thermodynamics, irreversible processes and energetics.
- The second part, chaired by Valerio Lembo and Gabriele Messori, will illustrate some applications of thermodynamics to the study of the climate system and its general circulation.
Public information:
The short course will be structured as such: - Part 1 (45 mins): theoretical background, by Remi Tailleux;
- Short break (5 mins);
- Part 2 (15 mins): diagnosing thermodynamics in climate models, by Valerio Lembo;
- Part 3 (10 mins): dynamics and heat transports in the atmosphere, by Gabriele Messori;
Metallurgical slags are generated as a by-product of smelting during ironmaking, steelmaking, and the production of ferroalloys and non-ferrous metals. The formation conditions result in complex (geo)chemical and mineralogical characteristics unique to slags alone. Historically slags have been discarded as a waste product and, through release of potentially toxic trace elements, represent a hazard to the environment and human health. However, increasingly we are realizing the resource potential of what was previously thought of as waste, thus reducing the environmental impact and taking a step closer to a circular economy.
The aim of this short course is to is to give an overview on the environmental geochemistry and resource potential of metallurgical slags by summarizing processes for the generation of slags, describing their chemical and mineralogical characteristics, outlining the fundamental geochemistry that propels slag weathering, and illustrating the utilization of slags and resource recovery of valuable metals from slags. This short course is a follow up of a book entitled “Metallurgical Slags: Environmental geochemistry and Resource Potential” published in 2021 by the Royal Society of Chemistry and gives an overview useful for the environmental geochemists, geologists, mining and civil engineers, waste and resource managers, and all those interested and inspired by a circular economy and minimizing our environmental footprint on planet Earth.
List of presentations:
1. Presentation of the book: Metallurgical Slags: Environmental Geochemistry and Resource Potential (Vojtěch Ettler and Nadine Piatak)
2. Metallurgical overview and production of slags (Elias Matinde, MINTEK, South Africa)
3. Geochemistry and mineralogy of slags (Nadine Piatak, USGS, USA)
4. Weathering of slags (Jakub Kierczak, University of Wroclaw, Poland)
5. Leaching properties and environmental fate of slags (Vojtech Ettler, Charles University, Czech Republic)
6. Environmental applications of slag (Helena Gomes, University of Nottingham, UK)
7. Metal recovery from slags (Anna Potysz, University of Wroclaw, Poland)
8. Discussion and course closure
Within this course, the attendees are taught how to identify possible cyclicities in paleoclimate data (e.g., sediments, speleothems) or any other geological record. We will start from the basics of which data can be analysed, go over power spectra, and discuss the application of filters and Wavelet Analysis. We will discuss the advantages and disadvantages of different methods, and give some examples from Earth Sciences to highlight common pitfalls. The aim of this course is to give a brief overview of the most common techniques and give participants the insight to prepare and analyse their data themselves. A variety of computational platforms are available for time-series analysis. In this course, we will introduce different tools and techniques by making use of the programming language R.

Most geoscientific research takes place in a certain geographic place, and therefore we almost always need to create a study area map. This short course will be a practical hands-on session for making a beautifully stylized study area map from scratch using open-source software QGIS. We will show where to download global open data and create a map with all the necessary map elements (title, legend, scale bar, north arrow) and an inset map showing the location of the main map in the context of a larger area. In addition, we will present the state-of-the-art "do's and don'ts" of cartographic design based on cases from the published research papers.
Public information:
To actively participate in the session, you would need to bring your laptop and install QGIS which can be freely downloaded from here: https://qgis.org/en/site/forusers/download.html
The recommended version is QGIS Standalone Installer Version 3.22. Version 3.24 is not recommended because it is not stable.
If you wish then you can bring your own study area border as shp or gpkg file.
In many scientific disciplines, accurate, intuitive, and aesthetically pleasing display of geospatial information is a critical tool. PyGMT (https://www.pygmt.org) - a Python interface to the Generic Mapping Tools (GMT) - is a mapping toolbox designed to produce publication-quality figures and maps for insertion into posters, reports, and manuscripts. This short course is geared towards geoscientists interested in creating beautiful maps using Python. Only basic Python knowledge is needed, and a background in cartography is not required to use PyGMT effectively! By the end of this tutorial, students will be able to:
- Craft basic maps with geographic map frames using different projections
- Add context to their figures, such as legends, colorbars, and inset overview maps
- Use PyGMT to process PyData data structures (xarray/pandas/geopandas) and plot them on maps
- Understand how PyGMT can be used for various applications in the Earth sciences and beyond!
The 1.5 hour long short course will be based on content adapted from https://github.com/GenericMappingTools/2021-unavco-course and https://github.com/GenericMappingTools/foss4g2019oceania. Each of the 30 minute sessions will involve a quick (~10 minute) walkthrough by the speaker, followed by a more hands-on session in breakout rooms where tutorial participants work on the topic (using interactive Jupyter notebooks) in a guided environment with one of four instructors on hand to answer questions.
We expressly welcome students and geoscientists working on any geo related fields (e.g. Earth Observation, Geophysical, Marine, Magnetic, Gravity, Planetary, etc) to join. Come and find out what PyGMT can do to level up your geoprocessing workflow!

Geotagged photographs provide unique insights into the plurality of geographic tasks - from land use/land cover classifications to biodiversity, hazardous events, and people's well-being monitoring. Millions of passively and actively crowdsourced geotagged photographs are available online in open access via social media platforms (Twitter, Flickr, VK.com) and citizen science initiatives. However, handling big photo datasets requires advanced data science skills. This short course presents the democratised digital tools for image analytics and classification: TensorFlow deep learning classification model, implemented in Microsoft's Lobe software, and image analytics tools in Orange data mining software. Participants will learn the basics of image analytics, the difference between supervised and unsupervised classification, quality assessment and optimisation techniques for deep learning image classification models.
Public information:
In this session, we will solve the classification task for the dataset of geotagged Flickr photographs using hierarchical clustering and a custom deep learning model. No coding skills are required. Participants are expected to install Orange https://orangedatamining.com/download/#windows and Lobe https://www.lobe.ai/ to their own laptops in advance. In Orange go to Options - Add-ons... and install 'Image Analytics' add-on before workshop.
During the recent years, it has become more and more obvious that soil structure plays a fundamental role in regulating processes in soils. As soil structures are hierarchical, complex and highly variable, studies involving soil structures require a relatively large number of replicate samples. Three-dimensional X-ray imaging provides an excellent tool to map out soil structure, but image analyses are still time intensive and require experience. This limits the number of X-ray images, and thus replicate samples that can be analyzed within reasonable time scales. SoilJ is an open-source and free plugin for the open-source image processing software ImageJ. It is tailor-made for the analyses X-ray images of soil and aims at automatizing the necessary image processing and analyses steps. This course gives a short introduction into X-ray image processing and analyses in general and specifically with SoilJ, provides an overview about SoilJ functionalities and offers guidance for researchers interested in participating in developing their own plugins.

We have developed an open source software package in python for ground-based GNSS reflections – gnssrefl (https://github.com/kristinemlarson/gnssrefl). This new software supports geoscientists wishing to measure in situ snow accumulation, permafrost melt, firn density, tides, and lake/river levels. We have developed videos (hosted on youtube) to help new users understand both the basic concepts of GNSS reflections and how to install and run the gnssrefl code. More than a dozen use cases are available online; Jupyter Notebooks have been developed as well. We envision the EGU tutorial session to be hands-on and interactive, with a focus on demonstrating the gnssrefl software and online tools (https://gnss-reflections.org), examining and discussing environmental results derived from GNSS data taken from public archives, and analyzing new datasets suggested by the students.
Public information:
We have developed an open source code in python (gnssrefl) that allows users to measure either water levels or snow accumulation using GNSS data. This session will be devoted to helping users understand how to run and install the code. Please see the github (https://github.com/kristinemlarson/gnssrefl) repository for some tips on how to install the gnssrefl package on your local machine. We currently support the python code on linux and macs, with docker images for these and PCs. We also have links to jupyter notebooks. There is a complementary web app at https://gnss-reflections.org.
Database documentation and sharing is a crucial part of the scientific process, and more and more scientists are choosing to share their data on centralised data repositories. These repositories have the advantage of guaranteeing immutability (i.e., the data cannot change), which is advantageous in the context of preserving published data "as-is" but is not so amenable to developing living databases (e.g., in continuous citizen science initiatives).
Distributed databases offer an innovative approach to both data sharing and evolution. Since these databases exist entirely on peer-to-peer systems, the distinction between "server" and "client" is blurred and the data residing on each individual device that is accessing it (whether personal computer, mobile phone or server) are equally valid sources of truth that can share data with new peers. These systems therefore have the distinct advantage of becoming more resilient and available as more users access the same data, with significant potential to decrease server costs and entry barriers for citizen science initiatives. At the same time, behind-the-scenes cryptography automatically ensures that the data is valid and cannot be tampered with by intermediary peers.
Distributed databases can also be configured to mirror exising databases in other formats, so that scientists can keep working in their preferred Excel, OpenOffice, SQL or other software while automatically syncing database changes to the decentralised web in real time.
This workshop will present the general concepts behind distributed, peer-to-peer systems with a particular emphasis on the context of scientific data sharing. Attendees will then be guided through an interactive activity on Constellation, a new scientific software for distributed databases, learning how to both create their own databases as well as access and use others' data from the network.

MTEX (https://mtex-toolbox.github.io/) has become a standard tool for the quantification of crystallographic textures and microstructural-derived physical properties in geological materials. From the quantification of crystallographic preferred orientations (CPOs), intracrystalline deformation, grain sizes and shapes in geological materials, to determination of CPO-derived physical properties (e.g., elastic, piezoelectric), all is possible with MTEX.
In the first part of the short course, we will introduce basic concepts on how MTEX works. In the second part, we will run demonstrations of some application in geological materials.
The following topics will be covered:
1) Importing EBSD data, pre-processing;
2) Checking orientations, ODF quantification, plot of pole figures;
3) Grain segmentation, calculation of grain sizes and shapes;
4) Intracrystalline deformation analysis, subgrains, new grains;
5) Tensors and CPO-derived seismic properties
Demonstrations will be made using the MTEX toolbax in Matlab. Note, however, that familiarity with the toolbox is not required. - This is a short course, not a workshop.

The main objective this workshop is introducing the attendees to practical use cases for Discrete Global Grid Systems (DGGS) for spatial data aggregation and analysis. After a short background on current real-world software implementations with exemplary use cases, we walk through an interactive exploration of solving traditional GIS and spatial analysis challenges with a hexagonal DGGS on the example of Uber H3. H3 is a software library that, besides many other programming languages, can be used in Python. We demonstrate grid generation, data indexing and sampling in a unified Jupyter notebook. We apply spatial analysis methods that exploit the specific grid properties and discuss eventually DGGS for datacube applications.The main objective of this workshop is to introduce the attendees to practical use cases for Discrete Global Grid Systems (DGGS) for spatial data aggregation and analysis.

This Short Course is aimed at researchers in climate-related domains, who have an interest in working with climate data. We will introduce the ESMValTool, a Python project developed to facilitate the analysis of climate data through so-called recipes. An ESMValTool recipe specifies which input data will be used, which preprocessor functions will be applied, and which analytics should be computed. As such, it enables readable and reproducible workflows. The tool takes care of finding, downloading, and preparing data for analysis. It includes a suite of preprocessing functions for commonly used operations on the input data, such as regridding or computation of various statistics, as well as a large collection of established analytics.
In this course, we will run some of the available example recipes using ESMValTool’s convenient Jupyter notebook interface. You will learn how to customize the examples, in order to get started with implementing your own analysis. A number of core developers of ESMValTool will be present to answer any and all questions you may have.
The ESMValTool has been designed to analyze the data produced by Earth System Models participating in the Coupled Model Intercomparison Project (CMIP), but it also supports commonly used observational and re-analysis climate datasets, such as ERA5. Version 2 of the ESMValTool has been specifically developed to target the increased data volume and complexity of CMIP Phase 6 (CMIP6) datasets. ESMValTool comes with a large number of well-established analytics, such as those in Chapter 9 of the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) (Flato et al., 2013) and has been extensively used in preparing the figures of the Sixth Assessment Report (AR6). In this way, the evaluation of model results can be made more efficient, thereby enabling scientists to focus on developing more innovative methods of analysis rather than constantly having to "reinvent the wheel".

Soil moisture is a key variable needed for application in climatology and hydrology. Knowledge about soil moisture is important to understand the ecosystems feedback to global climate change. Remote sensing can assist with deriving spatial soil moisture data on a regular basis. Particularly, optical remote sensing can be used to estimate soil moisture with unprecedented satellite archives (>30 years of Landsat) at high spatial resolution (30 m) globally.
Optical Trapezoid Model (OPTRAM) has shown high accuracy in soil moisture estimation over mineral and organic soils. OPTRAM utilises NIR and SWIR spectral regions that are sensitive to the water content in soil and vegetation. In wetlands, OPTRAM can also be used to derive information about groundwater position. Deriving soil moisture information with OPTRAM is a complex task that requires skills in processing remote sensing images, coding and analysing spatiotemporal data.
In this workshop, we will present the workflow needed for OPTRAM calculation in open-source R software. We will guide the participants on several key points:
- sources to derive optical remote sensing data;
- spatial data wrangling;
- estimation of OPTRAM;
- plotting of spatial data;
- interpretation of results.

QuakeMigrate is a new, open-source software package for automatic earthquake detection and location (https://github.com/QuakeMigrate/QuakeMigrate). Our software provides a means for seismologists to extract highly complete catalogues of microseismicity from continuous seismic data, whether their network is installed at a volcano, plate-boundary fault zone, on an ice shelf, or even on another planet. Rather than traditional pick-based techniques, it uses a migration-based approach to combine the recordings from stations across a seismic network, promising increased robustness to noise, more accurate hypocentre locations, and improved detection capability. Cloud-hosted Jupyter Notebooks and tutorials (https://mybinder.org/v2/gh/QuakeMigrate/QuakeMigrate/master) provide an overview of the philosophy and capabilities of our algorithm, and in this session we intend to provide a more hands-on introduction, with a focus on providing a general understanding of the considerations when applying a waveform-based algorithm to detect and locate seismicity.
QuakeMigrate has been constructed with a modular architecture, to make it flexible to use in different settings. We will demonstrate its use in detecting and locating basal icequakes at the Rutford Ice Stream, Antarctica, volcano-tectonic seismicity during the 2014 Bárðarbunga-Holuhraun and 2021 Reykjanes/Fagradalsfjall dike intrusions, and aftershocks from a M5 tectonic earthquake in northern Borneo, which was recorded on a sparse regional seismic network. In each case we will discuss the reasoning behind parameter selections, and the key factors in maximising detection sensitivity while minimising computational cost. We will end the session by exploring sample datasets provided by attendees, with interactive involvement as we tune parameters and use the comprehensive array of automatically generated plots to take a preliminary look at unseen data.

Changes in temperature in landslide bodies can be the result of external forcing (climatic or geothermal) as well as the consequence of frictional heat dissipation. Understanding and quantifying the mechanical response of geomaterials under thermal forcing can be crucial for predicting the initiation and fate of landslides, and the associated risk. Depending on the scale of interest, different modelling strategies have been developed, spanning from physically-based fully-coupled models accounting for micro-scale behaviours to large-scale geostatistical approaches. This short course aims to offer an overview of these modelling strategies with particular attention to state-of-the-art advances. The session is organized in cooperation with NhET (Natural hazard Early career scientists Team).

Channels can include in-person interaction, online, social media, mass media, or other methods. This session invites presentations by individuals and teams on science communication practice, research, and reflection, addressing questions like:
- What kind of communication efforts are you engaging in and how you are doing it?
- How is social science informing understandings of audiences, strategies, or effects?
- What are lessons learned from long-term communication efforts?
This session, run at both AGU and EGU, invites you to share your work and join a community of practice to inform and advance the effective communication of earth and space science.

Interdisciplinary collaboration between artists and geoscientists are becoming increasingly invaluable in communicating complex geoscience subjects to non-experts. Topics such as climate change can be contradictory and confusing to the general public, particularly in terms of uncertainty and impact. It is therefore vital that STEM communicators work to find alternative methods to enable dialogue between experts and the wider public on how to face and respond to these increasingly prevalent topics. It is becoming increasingly evident that both the scientific and the artist communities have a shared interest and responsibility in raising awareness of the limits to our planetary boundaries and the fragile stability and resilience of our Earth-System. In the past, this issue has been addressed mostly through traditional educational methods. However, there is mounting evidence that science-art collaborations can play a pivotal and vital role in this context by co-creating new ways of research and by stimulating the discussion by providing emotional and human context through the arts.
This session will combine a traditional academic poster session showcasing interdisciplinary research which will explore the dialogues between the geosciences and the arts alongside a display of art that aims to visually showcase these practises in action. Through symbiotically mixing STEM and the arts together in this way, the session aims to enable a discussion on how to use the two to explore and communicate the social, economic, political and environmental factors facing society and drive improved communication. In this edition, there will be a special spotlight on science/art collaboration that has been used to tackle the topic of planet sustainability.

Games have the power to ignite imaginations and place you in someone else’s shoes or situation, often forcing you into making decisions from perspectives other than your own. This makes them powerful tools for communication, through use in outreach, disseminating research, in education and teaching at all levels, and as a method to train the public, practitioners and decision makers in order to build environmental resilience.
Games can also inspire innovative and fun approaches to learning. Gamification and game-based approaches add an extra spark of engagement and interaction with a topic. Gaming technology, like virtual reality, transports and immerses people into new worlds providing fascinating and otherwise impossible experiences for learners.
In this session we welcome contributions from anyone who has used games, gaming technology, and/or game-based approaches in their research, their teaching, or public engagement activities.
Celebrating its fifth year, the session will be supported by the legendary Games4Geo Games Night providing an opportunity to share and try games presented in this session. We welcome continuation of discussions in our Discord server - https://discord.gg/teQXBh5

The work of scientists does not end with publishing their results in peer-reviewed journals and presenting them at specialized conferences. In fact, one could argue that the work of a scientist only starts at this point: outreach. What does outreach mean? Very simply, it means to engage with the wider (non-scientific) public about science. There are many ways to do outreach, including blogging and vlogging, using social media, writing for a science dissemination journal, participating as a speaker at local science festivals, organising open days in the laboratory, and so on.
With this short course, we aim to give practical examples of different outreach activities, how to start an outreach project and tips and suggestions from personal and peers’ experiences. Specific attention will be paid to science communication issues, including the proper ‘translation’ of the jargon of science into language the public understands, the selection of the content being conveyed, and the best format in which it is presented according to the different targets (policymakers, the general public, school-age children, etc.).
In the last part of the course, you will work singularly to come up with an outreach idea based on your research. You may use it on your next proposal; you never know!

Poetry can be a very effective tool in communicating science to a broader audience, and can even help to enhance the long-term retention of scientific content. During this session, we will discuss how poetry can be used to make your science more accessible to the world, including to your colleagues, your family, your friends, and other publics.
We aim to maximise empowerment and minimise intimidation, and in this fully interactive session, participants will have the opportunity to work on poems that help to communicate their research, and will be provided with feedback and advice on how to make them more effective, engaging and empathetic.

Strengthening society’s resilience and enabling people to better handle natural disasters is a joint endeavor various international frameworks pursue (e.g., Sendai Framework, Paris Agreement). An important role in enhancing resilience plays the appropriate and effective communication of information before, during and after an event. To this end, one has to know its audiences, build relationships with involved stakeholders and iteratively develop and test different communication products and services. Good communication is tailored to its audiences and motivates them to take preventive and even life-saving actions.
This session aims at gaining a better understanding of how to best communicate dynamic hazard and risk information to various non-expert stakeholders in the respective field including the public, decision makers or critical infrastructure owners. Welcomed are submissions exploring different means for sharing hazard and risk information related to earthquakes and other natural or anthropogenic hazards taking into account different aspects (e.g. format, medium, stakeholders, cultural context, temporality, uncertainties). Of special interest are submissions that discuss the dynamics of hazard and risk information as crises evolve and different approaches might be needed at different stages. Of particular interest are contributions related to information supporting people in taking immediate actions as well as case studies or best practices at different stages of the hazard and risk cycle.
We invite everyone dealing with hazard and risk communication at any stage of the hazard and risk cycle to hand in a contribution, namely researchers, practitioners, journalists, educators, and policy makers. The diversity of participants will enrich the discussions of this session.
Climate change (CC) and ocean degradation (OD) are among the greatest threats to humanity. Climate impacts the ocean in massive ways; the ocean is the climate’s most powerful regulator. Separately or combined, they impact every living being and ecological niche, with poorer communities suffering disproportionately. In turn, flora and fauna (incl humans) are suffering. CC and OD are affecting the cryosphere, biodiversity, and food and water security. Given that humans are the prime cause of this devastating change taking us beyond our planetary boundaries, geoethical issues come to the fore.
The 2020 EGU Declaration of the Significance of Geoscience highlights the need for massive and widespread action to help people around the world to become literate about the changes affecting their and their offsprings’ and communities’ lives. The more people are literate about these changes, the more they can make informed decisions, adapt and mitigate. Previous General Assemblies have addressed climate change literacy (CL). Ocean literacy (OL) has developed strongly in recent years, especially with impetus from the UN Ocean Decade. Ocean-climate literacy (OCL) is an imperative that needs to be addressed massively and urgently, both within and beyond the EGU.
We invite colleagues to submit contributions on any aspects of OCL; this can, of course, include CL (without the ocean) and OL (without the climate). We welcome papers related, eg, to learning processes/experiences, instructional materials, curricular innovation, learning games, citizen initiatives, Ocean Decade activities, evaluation, well-used methods, novel approaches and policies, eg, 1. make OCL an essential component in all subjects and at all levels of education; 2. require all people in positions of responsibility (eg, mayors, teachers, doctors, CEOs, ministers, et al) to pass exams on the basics of climate and/or ocean before taking office. Of particular interest are literacy actions that bring in geoethical dimensions. (If your paper is primarily on geoethics, then a better home is the EGU session on geoethics.) The broad aims of such OCL might include encouraging an intergenerational outlook, developing a sense of the geoethical dimensions of OCL, understanding complexities and implementing solutions.
This session is an opportunity for ECSs, scientists, educators, policy influencers, learning resource developers and other practitioners to share their experience, expertise and research on CL and OL.

The Covid-19 pandemic constrained many educational institutions to virtual learning environments and significantly reduced in person delivery. This was particularly difficult for subjects focused on acquiring practical skills conventionally taught through hands-on methods (labs, practicals, field courses etc). Consequently, novel approaches have been developed to maintain learning outcomes.
This session is an opportunity for scientists, educators, and other practitioners to share and explore the creative and innovative ways practical teaching has been implemented within a geosciences environment.
This may be the first time you are presenting at a big international meeting. Or the 37th. You want to do a good job – to promote your work, to get that postdoc position, to secure an invited talk at the next conference. And the experts in the field will be there, those whose papers you read and whom you admire or want to impress. You do not want to waste their time. But you are nervous – heart pounding, knees shaking, red spots all over your face, hands sweaty and trembling – and to make things even worse, all the other people in your session give splendid talks. It is your turn next, you will have to get up and walk to the podium (will your legs carry you?), you will have to give your talk (will your voice be ok?), and you will have to answer questions (what if you cannot answer, or do not understand them?). Applause. You have no idea what the person just talked about. But considering the applause it must have been great. Your talk will be a mess. The convener is calling your name. Can you do it?
This course deals with what scientists normally do not talk about – giving presentations, often in a foreign language, is scary and stressful. We have all been there. We will share strategies how to deal with it. And we will provide a platform for the questions you did not dare ask your supervisor.

Following the success of previous years, this session will explore reasons for the under-representation of different groups (cultural, national and gender) by welcoming debate among scientists, decision-makers and policy analysts in the geosciences.
The session will focus on both obstacles that contribute to under-representation and on best practices and innovative ideas to remove those obstacles. Contributions are solicited on the following topics:
- Role models to inspire and further motivate others (life experience and/or their contributions to promote equality)
- Imbalanced representation, preferably supported by data, for awards, medals, grants, high-level positions, invited talks and papers
- Perceived and real barriers to inclusion (personally, institutionally, culturally)
- Recommendations for new and innovative strategies to identify and overcome barriers
- Best practices and strategies to move beyond barriers, including:
• successful mentoring programmes
• networks that work
• specific funding schemes
• examples of host institutions initiatives
- COVID- related data, discussions and initiatives
This session is co-organised with the European Association of Geochemistry (EAG) and the European Research Council (ERC).
Sexual and racial harassment and other hostile behaviors, including bullying and other forms of discrimination and incivilities, have wide-ranging detrimental effects on mental and physical wellbeing, including anxiety, depression, and physiological responses akin to trauma, and can result in decreased motivation and work productivity. The tolerance of hostile behaviors can affect the community beyond the individual or individuals being targeted, and create negative work environments in entire research groups and departments. Traditional hierarchical structures within academia that create strong power imbalances allow for the potential for abuse in research and educational environments. Despite this, scientists often do not receive mentoring or training in how to address, respond to, and prevent these types of behaviors. Questions including “What behaviors are appropriate at work?”, “How do we create a work environment where people of different age, gender and sexual identity, culture, religion, ethnic origin and social class feel respected and included?” and “What can I do personally against bullying and sexual harassment at work?” are important topics that are not discussed enough in academia. Promoting conversations about these topics and identifying ways to prevent unwanted behavior are important steps towards building respectful and productive work environments.
This interactive short course explores academic practices and institutional structures that allow for harassment and other hostile behaviors to persist, discusses initiatives to address harassment as scientific misconduct, and provides training in personal intervention strategies to protect and support targets of harassment through real world scenarios. As a result of this session, participants will be able to identify:
(1) Different ways in which harassment can manifest in research environments;
(2) Strategies for bystander intervention, and
(3) Resources for cultural change in the office, laboratory, at conferences and in field settings.
This workshop was developed by ADVANCEGeo (serc.carleton.edu/advancegeo) with a U.S. National Science Foundation ADVANCE Partnership award in collaboration with the Earth Science Women's Network, the Association for Women Geoscientists and the American Geophysical Union. We welcome participants from a diverse background of Geosciences, career stages and countries.
How can geosciences serve society in addressing global anthropogenic changes, such as climate change, hazards and risks, natural resources exploitation? Which is the societal role geoscientists play within society? How much ethics is important in geosciences?
These are only some of the fundamental questions that modern geoscientists, aware of the ethical implications of their profession, should ask themselves.
As any scientist, geoscientists have responsibilities in developing excellent science and international cooperation, as well as in communicating scientific knowledge to different stakeholders. Specifically, geoscientists have great responsibility in creating methods and technologies for assuring people’s safety and a responsible use of planet Earth as entity and of its georesources, to guarantee public welfare and sustainable life conditions for present and future generations.
The complexity of the world and problems affecting it requires interdisciplinary approaches and cooperation, capable of synthesizing a range of knowledge, methods, tools. This is one of the goals of promoting geoethical thinking.
The purpose of this session is to create an opportunity for thinking and discussing about ethical, societal and social implications of global problems investing issues at the intersection between geosciences, humanities, and social sciences, with the objective of framing global anthropogenic changes as the crisis of the 21st century.
Conveners invite colleagues to confront on these topics from their professional perspectives, by presenting concepts, investigations, experiences, methods, problems, practices, case studies on ethical, societal and social perspectives to address global warming, exploitation of natural resources, risk reduction, conservation of geoheritage, science communication and education, to provide food for thought and create connections between different disciplinary fields, with the aim to build a genuine interdisciplinary community.
This session celebrates 10 years since the foundation of the IAPG - International Association for Promoting Geoethics (https://www.geoethics.org), and is co-sponsored by AGU - American Geophysical Union, CIPSH - International Council for Philosophy and Human Sciences, and IUGS - International Union of Geological Sciences.

Rationale
The proper and deep education on ethical issues in geosciences has been evolving in recent times, although not as quickly and deeply as necessary. Many of the professionals dedicated to Earth Sciences have been not in touch with such new concepts and tendencies. Geoethics is the research and reflection on the values that underpin appropriate behaviors and practices, wherever human activities interact with the Earth system. It provides a framework to define ethical professional behaviors in Earth sciences and engineering and to determine how these should be put into practice for the benefit of environment and society. The Short Course is directed towards introducing and training Earth scientists in those new concepts and ideas as well as exposing the perspectives of this field. Social-ecological Systems and the anthropic impact on land, ocean, and atmosphere are at the cores issues to be discussed under the umbrella of geoethics, as a tool to cope with Climate Changes and other earth-society related challenges.
Completing this course, participants
1. Will know the basic principles of ethics and how these lead to geoethics
2. Will be aware of the dilemmas involved in making geoethical decisions
3. Will have gained some experience in taking a geoethical approach to real world cases
Course Content: (provisional):
1. From Ethics to geoethics: definition, values, tools
2. Responsible conduct of research and professionalism
3. Tools for confronting (geo)ethical dilemmas
4. Geoethics for society: sustainable development and responsible mining
5. Geoethics in natural hazards
6. Education challenges in geoethics
7. Geoethics in geoscience communication
8. Recent developments in geoethical thinking
9. Perspectives of geoethics
10. Geoethics’ case studies: Water Management, Ocean Governance, etc.

In recent years, the geoscience community has been making strides towards making our science more open, inclusive, and accessible, driven both by individual- or community-led initiatives. Open-source software, accessible codebases and open online collaboration resources (such as GitHub, VHub, etc.) are becoming the norm in many disciplines. The open-access publishing landscape has been changing too: several geoscience journals have defined data availability policies, and many publishers have introduced green and gold open-access options to their journal collections. Pre-print servers and grassroots diamond open-access journals are changing the readiness with which scholarly content can be accessed beyond the traditional paywall model.
However, good scientific practice requires research results to be reproducible, experiments to be repeatable and methods to be reusable. This can be a challenge in geosciences, with available data sets that are becoming more complex and constantly superseded by new, improved releases. Similarly, new models and computational tools keep emerging in different versions and programming languages, with a large variability in the quality of the documentation. Moreover, how data and models are linked together towards scientific output is very rarely documented in a reproducible way. As a result, very few published results are reproducible for the general reader.
This session is designed to gain a community overview of the current open-science landscape and how this is expected to evolve in the future. It aims to foster a debate on open science, lower the bar for engaging in open science and showcase examples, including software and other instruments for assisting open research. This may include software and tools, open science dissemination platforms (such as pre-print servers and journals), the teams driving the development of open-science resources and practices, and the regulatory moves towards standardising open access in the scientific community and what those policies mean in practice. This session should advance the discussion on open and reproducible science, highlight its advantages and also provide the means to bring this into practice.

One of today's challenges in the Earth sciences is the continuous evolution of technologies, making it hard for users and developers to be up to date and take advantage of the most advanced solutions.
On the other hand, there have never been such favorable conditions for the development of Earth observation based services and applications targeting both public and private sector.
For this session we invite abstracts that present operational applications for scientific services across the geosciences, including ocean research, forest monitoring, crop monitoring and more. By presenting these success stories we hope to initiate a discussion between different actors involved in making and using services addressing gaps and needs for faster uptake of Earth observation based services.

Film synopsis: "The world is crying out for a new model of leadership, but what is it?" One woman thinks she has the answer. Australian CEO and 'dreamer' Fabian Dattner, leads an international group of 76 female scientists on an Antarctic voyage designed to transform them "into the sort of leaders they want to be." Her hope is that once these women are primed to lead in science, they will be able to make meaningful change around the world. But on board Dattner's own leadership style and philosophy are both severely tested, as the women's deeply personal stories of workplace harassment and more are revealed. Set against the planet’s last untouched wilderness, The Leadership delivers an altogether unexpected and original reflection on what it takes to be a good leader, while unearthing the profoundly troubling systemic obstacles to women's advancement in science and beyond."

Join us in this live Teacher-Scientist Pairing Session coordinated by the EGU Education and Outreach Committees to promote geoscience education in schools. The event takes you to Caserta (Italy) to join Teresita Gravina and her school classroom together with Giuliana Panieri, a scientist from the Arctic University of Norway. The teacher and the scientist work together to guide the students in their quest for understanding the Arctic Ocean and the science behind how it is changing. This session is conducted primarily in Italian with live English translation, and is likely to be of interest to anyone interested in science education and outreach. For questions related to this session, please contact the convener.
Field-based experiences, such as participation in a remote field camp or in an offshore research expedition, are important components of geoscience education and research. Such experiences can be both empowering through synergistic collaboration and teamwork, but also intimidating when individuals are pushed beyond their comfort when confronted with unexpected or unwelcome situations. There exist additional barriers in terms of entry and inclusion for those with disabilities. Similarly, lack of sensitivity to cultural differences present an additional barrier to inclusivity. Reports of harassment (both sexual and non-sexual) remain high, particularly among those who do not identify as male.
Although these barriers are likely to be common across efforts, individuals and organisations often tackle these issues independently. Therefore, we propose a Town Hall platform that encourages discussion highlighting efforts and experiences of improving inclusivity in field-based geoscience. Although the exact topics that could be discussed are endless, we choose to focus on three themes:
• Fostering inclusivity and minimising harassment in isolated/remote environments
• Teamwork and the issue of hierarchy on research vessels and stations
• “Personal time is personal”: Accessible fieldwork for everyone
The Town Hall Meeting will begin with a short panel discussion with panelists discussing each of the three themes in turn. Then, participants will break into small groups that each discuss one of the three themes, with a focus on sharing initiatives that have and have not worked, as well as identifying remaining barriers to effective fieldwork that need to be addressed. Finally, each small group will report their collective discussions across the other small groups.
The aim of this Town Hall Meeting is to foster discussion between participants towards a collective and cohesive vision on tangible actions to make the next step towards inclusivity in geoscience fieldwork. Notes from each small group discussion will be compiled and a report disseminated to participants at the conclusion of EGU22.

We are pleased to welcome our three panelists, who have been at the forefront with innovative ways to increase inclusivity in the field sciences:

The AERIS atmosphere Data and Services Centre federates French national data management activities and atmospheric science expertise.
AERIS stores, distributes and combines all atmospheric research data like data from long-term observation, the results of major field or aerial surveys, measurements from satellites or the results of laboratory experiment.
AERIS not only generates products from observations, but also offers many services to aid data exploitation and survey campaigns, and to interface with models.
This Town Hall will 1) give an update on AERIS-produced data products to the EGU community, 2) demonstrate new options for accessing data products through AERIS data portals and 3) solicit feedback from the community about their experience with obtaining and using data for their applications.
We hope that participants will learn about types of atmospheric data available and how to access them, and meet some of the AERIS people who facilitate the use of the Atmospheric Satellite, in-situ, balloon, aircraft … data products, answer questions and receive feedback for future developments and improvements.
This panel session, organised by the EU Horizon 2020-funded project SO-CHIC (http://www.sochic-h2020.eu/), will discuss the latest developments in Southern Ocean climate science, including implications for the global climate system. The session will also give a summary of the recent SO-CHIC research cruise to the Southern Ocean aboard the S. A. Agulhas II.
Public information:
The ocean regulates the global climate by absorbing heat and carbon from the atmosphere and storing them in the deep seas away from the atmosphere for centuries. Most of this process is done in the Southern Ocean around Antarctica, due to its unique circulation system. The role of the Southern Ocean in absorbing heat and carbon is a key process in the global climate system that is not fully understood. It is also unclear how these processes might change in future. The EU-funded SO-CHIC project is working to address some of these gaps in understanding, with work focused on air-sea fluxes, upper and deep ocean ventilation pathways, the role of the Weddell polynya, impacts on the wider climate system, and variability and trends for the future of the Southern Ocean system. The project employs a combination of observational and modelling approaches to advance understanding. This session will explore SO-CHIC’s work and the latest understanding of Southern Ocean climate processes.
Draft agenda:
Welcome
Role of the Southern Ocean in the global climate system
What is happening in the Southern Ocean? Carbon and heat. What do we not know?
Weddell Polynya – a key component?
How will SO-CHIC fill the gaps? Updates from the SO-CHIC cruise
Moderated discussion and questions from the audience

Tropical upwelling regions play an active role in climate and oceanic biogeochemical cycles as well as supporting the most productive ocean food chains. They support the largest fisheries of the world and are home to a biodiverse marine environment. Anthropogenic impacts in these regions will therefore have disproportionately large consequences for human society. Climate change, fishing pressure and pollution will alter the tropical upwelling systems in the future. However, despite intense research activities in the past, process understanding in upwelling regions spanning the physical, biogeochemical, ecological and geological systems and their interactions remains poor. For example, model projections indicate that climate change could strongly impact the intensity of upwelling in these systems, but there is low confidence in even the sign of these changes. Existing observations are insufficient for models to make more robust projections. This is because (i) physical, chemical and biological components of the system have not been studied in a synergistic and mechanistic way, and (ii) existing observational campaigns have largely been snapshots in space and time within systems that are highly dynamic on multiple time scales. Ultimately, this uncertainty threatens adequate adaptation of legal and economic regimes for the sustainable exploitation of upwelling systems. To address these shortcomings, we propose to conduct a multi-scale, multidisciplinary, year-round observational campaign in the 2024-2026 time-frame in the eastern boundary upwelling system (EBUS) of the tropical North Atlantic.
With this meeting we would like to attract your interest in an multi-national Atlantic Ocean Upwelling Field Campaign, establish/foster international collaboration and discuss observational strategies.

The last years have seen the emergence of preprint servers dedicated to the Earth and Space Sciences, such as, EarthArXiv, ESSOAr, and the newcomer on the block: EGUsphere. These preprint servers allow sharing non-peer reviewed manuscripts in open access, thus increasing accessibility of the science. Preprint servers usually employ some form of screening before posting a preprint and also encourage public feedback on the preprints. Most publishers in the Earth Sciences accept manuscripts that have been preprinted.
In this townhall, we will share information on different preprint servers and discuss their similarities and differences in flavour. We aim for an open discussion on why to preprint, the pros and cons of preprinting, and in general, how the process works.
Preprinting in the Earth and Planetary Sciences (5 min talk and 5 min questions each):
19:10 – 19:20 arXiv with Steinn Sigurdsson
19:20 – 19:30 EarthArXiv with Giacomo Falchetta
19:30 – 19:40 ESSOAr with Matthew Giampoala
19:40 – 19:50 EGUsphere with Susanne Buiter
19:50 – 20:00 General Q & A / Discussion led by Berit Schwichtenberg: why would we preprint, what are the pros and cons of preprinting, what are the new developments/wishes?
Open access (OA) publishing provides unrestricted access to scientific publications.
OA represents a substantial contribution to the efforts of ‘open science’ that aim at transparency, reproducibility and accessibility of scientific results.
This Townhall Meeting brings together representatives of large geoscience publishers and geoscience organizations that apply different OA concepts in their journals.
Discussion topics will include:
- What are the different OA models?
- How does OA advance transparency in science?
- Which are (apparent) disadvantages of OA and how can they be overcome?
Speakers during this meeting will include
- Sarah Callaghan, Editor-in-Chief, Cell Press, Elsevier
- Gemma Cassidy, Senior Journals Publishing Manager, Wiley
- Heike Langenberg, Chief Editor of Nature Portfolio’s Communications Earth & Environment
- Ulrich Pöschl, EGU, founder of Atmospheric Chemistry&Physics

Two important sessions have taken place today, Tuesday, 24 May, 2022, one on geoethics, EOS4, the other on climate and ocean literacy, EOS1.8. These two areas are complementary. Geoethics deals with issues related to appropriate human behaviour and practices towards the Earth system, including global anthropogenic change. One major human-induced impact is global heating and ocean degradation. Thus, all climate and ocean literacy needs to recognize and teach geoethics. Simultaneously, geoethics must include issues such as climate and ocean among its topics.
This Townhall aims to start a wide-ranging conversation to bring these two interdependent areas closer together in concrete ways. Even if you missed one or both of the two main sessions, EOS4 and EOS1.8, you are welcome to join us and share your ideas and concerns. In addition, we expect Dr Svitlana Krakovska, Senior Scientist, Ukrainian Hydrometeorological Institute and IPCC author, to attend our Townhall Meeting, where she may give an informal presentation. To know more about her work, see https://www.theguardian.com/environment/2022/mar/09/ukraine-climate-scientist-russia-invasion-fossil-fuels. This will be a great opportunity to interact with Svitlana and to gain some insight into her views on fossil fuels, war and climate change – a theme that is relevant to climate change literacy.

Landslides, such as rockslides, rockfalls, and debris flows, have been occurring extensively in a large number of countries, typically Asian countries, causing heavy damage. Landslides have been studied in various research fields, such as geomorphology, geology, geophysics, Sabo engineering, geotechnics, but we need a common platform to exchange research results and make discussion to strengthen our activity. This session is such a place and we invite contributions that report and discuss on landslides and related phenomena, focusing on improved understanding of their characteristics; new insights into landslide mechanisms; the development of new approaches to monitoring; novel approaches to behavior forecasting and prediction; studies of successful landslide management; and the development of methods for hazard and risk evaluation.
Recent technical developments have enabled us to acquire high-definition topographic and geophysical data for geoscientific research, including land surface processes, subsurface structures, submarine/aerial environments, and geo-ecological interactions. Such high-definition or high-resolution data are particularly useful for studies on landscape developments in a relatively short-term (decadal to millennial time scales), which are often assessed with a concept of connectivity in spatial and temporal contexts. In this session, we expect submissions on topics challenging the issues of connectivity in the Anthropocene, the most recent geological era of the Earth affected by human activities. A range of topics would fit the session framework, including theoretical works, data acquisition, pre- and post-processing, extensive data preservation and archiving, statistical analysis, physical modeling, machine learning, and numerical simulation. The methodological approaches may include, but are not limited to, laser scanning (Lidar), photogrammetry (SfM), GNSS precise positioning, SAR interferometry, multi-beam sonar, ground-penetrating radar, geomagnetic/electromagnetic sensors, and multi/hyperspectral sensors, based on terrestrial (fixed or mobile), aerial (UAV or manned airborne), or satellite platforms.

Volatiles play an important role in the dynamical and chemical processes in the Earth. The presence of volatiles drastically changes mineral stability and rheological behavior of the rocks. Chemical fractionation, such as partial melting, hydration, and dehydration are controlled by volatiles in the rocks. Volatiles enhance the production of magmas and drive their ascent and volcanic eruption. The atmosphere and hydrosphere have been generated by variety of degassing events from the mantle through volcanism. Some volatiles in the Earth's surface have been suggested to be recycled back into the mantle beyond subduction zones. Although the significance of volatiles in the Earth's evolution has been recognized, each of these processes is poorly constrained. We therefore welcome contributions from experimental, observational, and modeling studies that help shed light on the behavior, chemical/physical characteristic, and flux/budget of volatiles, such as hydrogen, carbon, nitrogen, noble gases, halogens, and sulfur. We encourage studies linking the behavior of multiple volatile elements and their isotopic compositions. Studies investigating the linkage between volatile and solid geochemical tracers, the phase equilibria of volatile-bearing mantle assemblages, and the effect of volatiles on the physical properties of the mantle are also welcome.
In order to reconstruct the Earth climate system, marine paleoclimatologists resort to transfer functions or geochemical proxies, which are produced or affected by organisms. The relationships used for reconstructions are generally based on field calibrations or derived from laboratory experiments. The danger of these so-called empirical relationships is that they may be valid only within the restricted parameter space of their calibration. Application of proxy relationships to very different environmental settings (e.g. high vs. low latitude or glacial vs. interglacial) requires a mechanistic understanding of these relationships. Much progress can be expected by a better understanding of the biomineralization mechanisms and the incorporation of proxy signals. In this session we facilitate contributions related to the biomineralization, calibration and validation of marine proxies from field study, laboratory culture experiment, biological & ecological studies and paleo-environmental reconstruction.
Cultural heritage (World Heritage Sites, historical structures, archaeological artifacts, etc.) and geoheritage (geosites, geoparks, etc.) are exposed to weathering in the geological and human time scale. The resulting deterioration of the rocks and other geological materials in cultural and natural contexts can be often severe and demands the prompt adoption of conservation measures. The relevant research involves a range of disciplines: mineralogy, geomorphology, geoarchaeology, environmental science, engineering geology, materials science, analytical chemistry, etc. However, our knowledge on many aspects is still limited. This session welcomes contributions presenting original research, case studies, and discussions on damage assessment, experimental techniques, monitoring, predictive models, conservation procedures, documentation, etc., related to geological materials in cultural heritage and geosites.

The increasing amount of data from an increasing number of spacecraft in our solar system shouts out for new data analysis strategies. There is a need for frameworks that can rapidly and intelligently extract information from these data sets in a manner useful for scientific analysis. The community is starting to respond to this need. Machine learning, with all of its different facets, provides a viable playground for tackling a wide range of research questions in planetary and heliospheric physics.
We encourage submissions dealing with machine learning approaches of all levels in planetary sciences and heliophysics. The aim of this session is to provide an overview of the current efforts to integrate machine learning technologies into data driven space research, to highlight state-of-the art developments and to generate a wider discussion on further possible applications of machine learning.

Through a wealth of geospatial data, growing computational power, and demonstrated success of application across many fields, artificial intelligence (in particular, machine learning) promises to advance our understanding of natural hazards and our ability to predict and respond to natural disasters. The ITU/WMO/UNEP Focus Group AI for Natural Disaster Management (FG-AI4NDM) is building a community of experts and stakeholders to identify best practices in the use of AI for data processing, improved modeling across spatiotemporal scales, and providing effective communication. This multidisciplinary FG-AI4NDM-session invites contributions addressing challenges related to floods, landslides, earthquakes, volcanic eruptions, tsunamis, among others, as well as multi-hazard. It also welcomes presentations on novel AI methods (including advances in automated annotation, explainability, etc.), which are hazard agnostic.
Unsupervised, supervised, semi-supervised as well as reinforcement learning are now increasingly used to address Earth system related challenges.
Machine learning could help extract information from numerous Earth System data, such as in-situ and satellite observations, as well as improve model fidelity through novel parameterisations or speed-ups. This session invites submissions spanning modelling and observational approaches towards providing an overview of the state-of-the-art of application of these novel methods for predicting and monitoring our earth system. This includes (but it is not restricted to):
- the use of machine learning to improve forecast skill
- generate significant speedups
- design new parameterization schemes
- emulate numerical models.
Please consider submitting abstracts focussed on ML applied to observations and modelling of climate processes to the companion "ML for Climate Science" session.
Recent developments in machine learning (ML) are transforming Earth observation data analysis and modelling of the Earth system and its constituent processes. While statistical models have been used for a long time, state-of-the-art machine and deep learning algorithms allow encoding non-linear, spatio-temporal relationships robustly without sacrificing interpretability. These advances have the potential to accelerate climate science by improving our understanding of the underlying processes, reducing and better quantifying uncertainty, and even making predictions directly from observations across different spatio-temporal scales.
This session aims to provide a venue to present the latest progress in the use of ML applied to all aspects of climate science including, but not limited to:
- Causal discovery and inference
- Learning (causal) process and feature representations in observations
- Hybrid models (physically informed ML)
- Novel detection and attribution approaches
- Probabilistic modelling and uncertainty quantification
- Explainable AI applications to climate science
Please consider submitting abstracts focussed on ML for model improvement, particularly for near-term (including seasonal) forecasting to the companion “ML for Earth System modelling” session.
Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

Groundwater, the hidden component of the water cycle, traditionally receives less attention than surface water from both the scientific community and policy makers, due to it being "out of sight, out of mind". However, this precious resource is inextricably linked to the maintenance of natural ecosystems and human well-being. Groundwater has always been part of the lives of worldwide communities: irrigated agriculture is primarily sustained by groundwater resources, particularly in arid and semi-arid regions; holy wells and sacred springs are part of our global cultural heritage, while disagreement over groundwater resources have previously resulted in turmoil and national/transboundary conflicts. These obvious interconnections, however, are neglected in favour of the development of sectorial approaches to groundwater resource assessment.
Socio-hydrogeology has recently been proposed as an effective approach to addressing complex groundwater-related issues in an increasingly holistic and integrated manner. By focusing on the reciprocity between humans and groundwater, it aims to explore and understand their dynamic interactions and feedbacks with a final goal of developing transdisciplinary solutions for transdisciplinary problems. Due to the more "personal" (i.e., individual household/community supplies) and local nature of groundwater in many instances, socio-hydrogeology seeks to understand individuals and communities as a primary source, pathway and receptor for potable groundwater supplies, including the role of local knowledge, beliefs, risk perception, tradition/history, and consumption. In essence, the “socio” in socio-hydrogeology embodies sociology, including social, cognitive, behavioural and socio-epidemiological science.
For this session we encourage contributions from diverse fields, including:
• Examples of socio-hydrogeological assessments (e.g., participatory monitoring, stakeholder engagement, public participation, citizen science)
• Integration of “non-expert” knowledge and experience within quantitative and qualitative hydrogeological studies
• Challenges and opportunities arising from the integration of hydrogeology and social sciences
• Social and political approaches to water resources research
• Groundwater geoethics and national/transboundary conflicts
• Attempts to integrate behavioural, experiential or knowledge-based data with hydrogeological/health risk assessment models
• Educational goals for future socio-hydrogeologists

Climate impact and adaptation research has made considerable progress in various fields in the recent years. However, the concrete implementation on the ground needs to be improved.
Local decision makers are facing several challenges with regard to climate adaptation. At the center of this process lies the coupling of climate, impact and risk (incl. vulnerability) models in order to identify future climate risk levels. Finding and correctly using the necessary data in climate impacts and risks assessments and planning for climate action is not without challenges for specialists from other fields.
While climate modelling and technical integration of diverse model data are crucial, social science as well as interdisciplinary perspectives are essential to assess local adaptation capacities, the costs and benefits of adaptive measures and to ensure the usability and transferability of the climate services. Similarly important is capacity building and trainings on properly using, interpreting and communicating climate and impact information.
This session touches upon innovative ways to address theses challenges. It also supports exchange on experiences in impact and adaptation studies, using all kinds of climate data. Former participants from the C3S ULS and IS-ENES3 training events are particularly encouraged to join.
This session discusses approaches and challenges towards the support of climate change adaptation and disaster risk reduction. Central to the discussion is the question how such services can be developed in a stringent co-design process that integrates different natural and social science disciplines as well as users and practitioners. We are therefore seeking for contributions that discuss:
• Actionable services for regional decision-making in regional climate adaptation and disaster risk reduction and challenges in the interaction between researchers and decision makers
• New scientific insights into regional climate and impact modelling (data interfaces and harmonization)
• Assessing local climate adaptation capacities and measures in an integrated way
• New insights into transdisciplinary processes in climate change adaptation
• Data availability for climate impact studies and methods for dealing with limited data availability as well as the opposite, a large number of seemingly similar datasets.
• Experiences with existing tools or newly developed tools for data processing
The virus is still with us, with more potent variants. It remains the most immediate challenge for geosciences and health, including its impacts on geoscience development (data collection, training, dissemination) and the achievement of the UN Sustainable Development Goals, in particular that urban systems should increase well-being and health.
Long-term visions based on transdisciplinary scientific advances are therefore essential. As a consequence, this session, like the ITS1.1 session in 2021, calls for contributions based on data-driven and theory-based approaches to health in the context of global change. This includes :
- main lessons from lockdowns?
- how to get the best scientific results during a corona pandemic?
- how to manage field works, geophysical monitoring and planetary missions?
- qualitative improvements in epidemic modelling, with nonlinear, stochastic, and complex system science approaches;
- eventual interactions between weather and/or climate factors and epidemic/health problems
- new surveillance capabilities (including contact tracing), data access, assimilation and multidimensional analysis techniques;
- a fundamental revision of our urban systems, their greening and their need for mobility;
- a special focus on urban biodiversity, especially to better manage virus vectors;
- urban resilience must include resilience to epidemics, and therefore requires revisions of urban governance.

The 2021-2022 Hunga Tonga-Hunga Ha'apai eruption in Tonga was among the largest of recent decades. The event was notable for its high intensity, generating a convective column that rapidly ascended well into the stratosphere; for the atmospheric pressure wave generated by the explosion, which was detected globally; and for generating a tsunami that was observable across Pacific Ocean shorelines. Following a series of preceding seismic and explosive events since December 2021, the sustained phase of the eruption on 15th January was relatively short lived, but the associated pressure wave and tsunami impacts were the most far-reaching since the eruption of Krakatau volcano in 1883. Tsunamis were recorded both locally and in the far-field, but their mechanism(s) remains uncertain; in the near field being from either (or both of) the collapsing eruption column or a phreatomagmatic explosion as the erupting mass mixed with sea water. In the far-field the tsunamis are possibly best explained by the massive atmospheric pressure wave, that is the first instrumentally recorded eruption-generated event of its type, which affected the entire global atmosphere and ionosphere, causing the observed infrasound waves and unusual long-period seismic resonances.
This interdisciplinary late-breaking session welcomes contributions from all disciplines involved in local and global observations of this eruption and its effects, including remote sensing observations and modeling as well as hazard assessment and estimation of damage and long-term consequences.
In a fast-changing environment, earth’s ecosystems are facing multiple stressors compromising the provision of essential services for mankind, and the resiliency of the natural environment itself.
Climate change, water pollution and scarcity affect biodiversity, socio-economic and climate related vulnerabilities and as a consequence, water and food security and human health.
The recent European Green Deal aims at Europe becoming the world’s first climate-neutral continent by 2050 and it does so by setting climate, energy, transport and taxation policies fit for reducing net greenhouse gas emissions by at least 55% by 2030. This program sets ambitious yet realistic targets for the next decades, auspicating the transformation of European Countries into a modern resource-efficient economy and society in line with the Sustainable Development Goals.
However, to address both the impacts as well as the causes of climate change, it is fundamental to create conditions where ecosystem services are optimized for both the local population and global objectives. Yet, the use of ecosystem services assessment in decision making might prove challenging when it comes to economic and social domains, as well as the perception and concept of natural environment may differ across disciplines. Such transdisciplinary approach plays a key role in Nature Based Solutions and opens up to the participation of multiple stakeholders in local governance, thus offering a multitude of co-benefits for the environment and for communities.
This session aims at opening a common ground between the natural, physical, social and economic sciences towards a resilient planet, by providing examples of challenges and opportunities and harmonizing best practices in this field.
We welcome transdisciplinary contributions on terrestrial, marine, and urban ecosystem services assessment that take into account the natural and the human dimension, advance in modelling complex spatio-temporal and social dynamics and transdisciplinary approaches towards nature inspired and supported solutions for social benefits and ecosystems’ resilience.

Nature-Based Solutions and Climate Engineering in Climate Governance
As reaching the Paris agreement goal of limiting the global mean surface warming even below 2ºC becomes increasingly difficult with only emission reduction, additional measures complementing greenhouse gas (GHG) emission reductions to limit global warming gain more attention: Nature-based Solutions and Climate Engineering.
Nature-based solutions (NbS) have gained popularity as a set of integrated approaches that contribute to climate change adaptation, slowing further global warming, supporting ecosystem services and biodiversity, while promoting sustainable development. To achieve the full potential of NbS to address climate change, there is an urgent need for multidisciplinary teams of scientists to articulate solutions that engage policy makers and enable NbS interventions to reduce carbon emissions while benefiting human well-being. This will require systemic change in the way we conduct research, promote collaboration between institutions and with policy makers.
Climate Engineering (CE) is much more controversial. Carbon Dioxide Removal (CDR) aims at removing CO2 from the atmosphere through techniques such as ocean fertilization, artificial upwelling or enhanced weathering. CE has been criticized for creating potentially dangerous side effects, distracting from the root cause of climate change (GHG emissions), and being difficult to govern. So what, if any, should be the future role of CDR and SRM in the climate governance toolbox and to what extent should CE research have high priority? which knowledge gaps must be addressed before a decision for or against these techniques can be taken?
This session aims to advance knowledge of innovative NbS approaches for more inclusive and resilient communities from inter-disciplinary perspectives.
Specific topics include, but are not limited to:
— Benefits: The potential of NbS and CE to help achieving climate goals
— Feasibility: Tools and best practices enabling successful implementation and upscaling of NbS; impact assessment of real-life NbS projects, especially for the Global South and developing countries; and technical feasibility and risks in implementing CE
— Viability: Cost-benefit analysis of NbS and CE to multiple Sustainable Development Goals
— Governance: New NBS governance models and co-creation approaches and tools; and regional and global challenges and solutions for fair and inclusive governance of CE.

Perhaps the most dramatic demonstration of the impact of global environmental change has been the rapid change in fire regimes, from the Amazon to suburban Athens. However, the observed disruption in global wildfire regimes has not yet been directly attributed to climate – but only to weather patterns that make wildfires more likely.
At the heart of this issue is a lack of understanding of the diverse socio-ecological feedbacks that are driving Anthropocene wildfires. For example, in response to damaging fire events, common policy responses such as increased suppression and fire use bans may ultimately exacerbate fire risk by leading to large build-ups of flammable and connected fuels. Meanwhile a combination of global-scale trade conflict, national-scale political change and regional drought have all contributed to a surge in wildfires in the Amazon basin. These examples highlight the urgent need for new transdisciplinary approaches to wildfire research that account for feedbacks between land use and wider environmental change.
In this session we welcome a broad range of contributions that explore the interactions between socio-economic and biophysical drivers of wildfires, encompassing disciplines including: anthropology, earth observation, ecology, economics, land surface and climate modelling, and political science. Example topics might include how agricultural intensification, land degradation and CO2 fertilisation effects combine to alter fire regimes in grassland ecosystems, through to how rural and urban populations’ contrasting perceptions of risk can influence land management policies.
We particularly encourage contributions that demonstrate how methods from different disciplines may inform each other. Holistic advances in our understanding can lead to better adaptation policies and strategies, and will be vital to improved wildfire modelling and attribution of fire regime changes to climate change.

1) Forecasting and simulating high impact weather events - research on improvement of high-resolution numerical model prediction of severe weather events (such as winter storms, tropical storms, and severe mesoscale convective storms) using data from various observational platforms, evaluation of the impact of new remote sensing data;
2) Development and improvement of model numerics - basic research on advanced numerical techniques for weather and climate models (such as cloud resolving global model and high-resolution regional models specialized for extreme weather events on sub-synoptic scales);
3) Development and improvement of model physics - progress in research on advanced model physics parametrization schemes (such as stochastic physics, air-wave-oceans coupling physics, turbulent diffusion and interaction with the surface, sub-grid condensation and convection, grid-resolved cloud and precipitation, land-surface parametrization, and radiation);
4) Model evaluation - verification of model components and operational NWP products against theories and observations, regional and global re-analysis of past observations, diagnosis of data assimilation systems;
5) Data assimilation systems - progress in the development of data assimilation systems for operational applications (such as reanalysis and climate services), research on advanced methods for data assimilation on various scales (such as treatment of model and observation errors in data assimilation, and observational network design and experiments);

7) Advances and challenges in high-resolution simulations and forecasting.
In weather prediction and climate modelling, numerical models of the Earth System are used extensively. For both the atmosphere and ocean components such models consist of a fluid dynamics solver (dynamical core) coupled to physical parameterizations to represent processes that occur below the grid scale (physics). Over time these models have become capable of sophisticated simulations. Research and development is constantly being undertaken to improve the accuracy, efficiency, and scalability of the dynamical core, the physics, and their coupling.
This session encompasses the development, testing and application of novel numerical techniques for Earth system models, including governing equations, horizontal and vertical discretizations, structure preserving methods, time stepping schemes, advection schemes, adaptive multi-scale models, physics-dynamics coupling, regional and global models, classical and stochastic physical parameterizations (that are not covered in other sessions).

This session invites presentations on high-resolution simulations of weather and climate. This includes state-of-the-art global storm-resolving simulations for weather and climate prediction but also large-eddy simulations and high-resolution ocean modelling. Presentations can cover developments to improve model fidelity (e.g. via improved parametrisations), detailed studies of modelled phenomena at high-resolution (e.g. tropical cyclones) and the impacts of ocean-atmosphere coupling. However, reflecting the technical challenges of such simulations, we also welcome presentations about computational concerns, such as the effective use of heterogeneous supercomputers (including GPUs), domain-specific languages, and the development of new, efficient dynamical cores. We also welcome presentations from participants of international projects related to high-resolution weather and climate simulation, such as DYAMOND, PRIMAVERA, Destination Earth, NextGEMS and WarmWorld.

The variability in the stratosphere is important for many atmospheric phenomena. Examples include the dynamical two-way coupling between the stratosphere and troposphere, the transport of trace gases through the meridional circulation of the stratosphere, or the connection between the Quasi-Biennial Oscillation of the tropical stratosphere and the Madden-Julian Oscillation. This session is interested in the causes for and consequences of stratospheric circulation variability, including the mechanisms behind the vertical coupling between the stratosphere and troposphere in tropics and extratropics, and the role of stratospheric dynamics for short-term atmospheric weather, sub-seasonal to seasonal predictability, and long-term climate variability. We welcome abstracts that study these problems from observational, modelling, or theoretical viewpoints on all temporal and spatial scales.

The field of infrasonic research, the science of low-frequency acoustic waves, has expanded to include acoustic-gravity waves and developed into a broad interdisciplinary field encompassing academic disciplines of geophysics and recent technical and basic scientific developments. The infrasound network of the International Monitoring Network (IMS) for nuclear test ban verification and regional cluster arrays deployed around the globe have demonstrated their capacity for detecting and locating various natural and anthropogenic disturbances in the atmosphere. Infrasound and acoustic-gravity waves are capable of traveling up to thermospheric altitudes and over enormous ranges, where their propagation is controlled by the wind and temperature structure. Recent studies have offered new insights on quantitative relationships between infrasonic observations and atmospheric dynamics, and therefore open a new field for atmospheric remote sensing.
New studies using lidar, radar, microwave spectrometer and mesospheric airglow observations complemented by satellite measurements help to better determine the interaction between atmospheric layers from the ground to the mesosphere and the influence of atmospheric waves on the mean flow. It is expected that further developing multi-instruments platforms would improve gravity wave parameterizations and enlarge the science community interested in operational infrasound monitoring. In a higher frequency range, the infrasound monitoring system also offers a unique opportunity to provide, in near-real time, continuous relevant information about natural hazards with high societal impact, such as large volcanic eruptions, surface earthquakes or meteorites.
We invite contributions on recent studies characterizing infrasound sources or large-scale atmospheric phenomena, including presentations utilizing acoustic waves to probe the atmosphere. Results and advances in acoustic propagation modelling and innovative instrumentation, which also encompasses the extension of regional array networks, are welcome. We also invite studies of the role that infrasound and acoustic-gravity waves play in the coupled Earth’s crust – ocean – atmosphere system and, in particular, in ionospheric manifestations of physical processes in the ocean and in the solid Earth. Contributions highlighting data products and services for civilian and scientific applications utilizing or supplementing infrasound observations are particularly encouraged.
Internal gravity waves (IGWs) still pose major questions both to the atmospheric and ocean sciences, and to stellar physics. Important issues are IGW radiation from their various relevant sources, IGW reflection at boundaries, their propagation through and interaction with a larger-scale flow, wave-induced mean flow, wave-wave interactions in general, wave breaking and its implications for mixing, and the parameterization of these processes in models not explicitly resolving IGWs. The observational record, both on a global scale and with respect to local small-scale processes, is not yet sufficiently able to yield appropriate constraints. The session is intended to bring together experts from all fields of geophysical and astrophysical fluid dynamics working on related problems. Presentations on theoretical, modelling, experimental, and observational work with regard to all aspects of IGWs are most welcome, including those on major collaborative projects, such as DataWave.

The subtropics present unique regional hydroclimates across the globe, with strong influence from both tropical and mid-latitude dynamics and an extensive interplay between atmospheric thermodynamics, dynamics, and coupled ocean processes. With dependence on both tropical and extratropical processes, subtropical regions are emerging as hotspots of contemporary climate change. These hotspots reflect the paleoclimatological records of high climate sensitivity in subtropical climes (e.g. Green Sahara and Arabia, pluvials in the drylands of southern Africa, Australia). The complexity of subtropical climates present fundamental challenges to develop coherent theories of subtropical climate dynamics, resulting in large uncertainties in climate model simulations. To address these gaps in the understanding of the subtropical climate, we invite contributions focused on subtropical processes and their simulation including:
• diagonal convergence zones
• tropical-extratropical interactions
• subtropical jet fluctuations
• interplays between monsoons and mid-latitude transients
• weather and climate extremes in the subtropics
• analyses of climate simulations looking into past, present and future change in the subtropics
• development of bespoke climate services based on advances in subtropical theory and prediction

• Model uncertainty representation in convective scale data assimilation
• Remote sensing observations at convective scales: data products, observing strategy, and technology
• Assessment of the impact of convective scale data assimilation development, and new observations, on prediction

The understanding of tropical phenomena and their representation in numerical models still raise important scientific and technical questions, particularly in the coupling between the dynamics and diabatic processes. Among these phenomena, tropical cyclones (TC) are of critical interest because of their societal impacts and because of uncertainties in how their characteristics (cyclogenesis processes, occurrence, intensity, latitudinal extension, translation speed) will change in the framework of global climate change. The monitoring of TCs, their forecasts at short to medium ranges, and the prediction of TC activity at extended range (15-30 days) and seasonal range are also of great societal interest.
The aim of the session is to promote discussions between scientists focusing on the physics and dynamics of tropical phenomena. This session is thus open to contributions on all aspects of tropical meteorology between the convective and planetary scale, such as:
- Tropical cyclones,
- Convective organisation,
- Diurnal variations,
- Local circulations (i.e. island, see-breeze, etc.),
- Monsoon depressions,
- Equatorial waves and other synoptic waves (African easterly waves, etc.),
- The Madden-Julian oscillation,
- etc.
We especially encourage contributions of observational analyses, modelling studies, and theoretical investigations of tropical cyclones and other synoptic-scale tropical disturbances including the physics and dynamics of their formation, structure, and intensity, and mechanisms of variability of these disturbances on intraseasonal to interannual and climate time scales.
Findings from recent field campaigns are also encouraged.

This session investigates mid-latitude cyclones and storms on both hemispheres. We invite studies considering cyclones in different stages of their life cycles from the initial development, to large- and synoptic-scale conditions influencing their growth to a severe storm, up to their dissipation and related socioeconomic impacts.
Papers are welcome, which focus also on the diagnostic of observed past and recent trends, as well as on future storm development under changed climate conditions. This will include storm predictability studies on different scales. Finally, the session will also invite studies investigating impacts related to storms: Papers are welcome dealing with vulnerability, diagnostics of sensitive social and infrastructural categories and affected areas of risk for property damages. Which risk transfer mechanisms are currently used, depending on insured and economic losses? Which mechanisms (e.g. new reinsurance products) are already implemented or will be developed in order to adapt to future loss expectations?

This session deals with atmospheric convection, being dry, shallow, or deep convection. Contributions on these aspects resulting from the use of large-eddy simulations, convection-permitting simulations, coarser-resolution simulations using parameterised convection and observations are welcome. Studies that investigate the organization of convection, being in idealized set-ups (radiative convective equilibrium and self-aggregation) or in observations, as well as studies that investigate the importance of organization for climate are particularly welcome. Besides this, studies that investigate general aspects of convection such as processes controlling the lifecycle of convection, interactions of convection with other physical processes and representation of convection in numerical weather prediction and climate models, being for instance through the use of machine learning techniques, are also welcome.

Precipitation, both liquid and solid, is a central element of the global water/energy cycle through its coupling with clouds, water vapor, atmospheric motions, ocean circulation, and land surface processes. Precipitation is also the primary source of freshwater, while it can have tremendous socio-economical impacts associated with extreme weather events such as hurricanes, floods, droughts, and landslides. Accurate and timely knowledge of precipitation characteristics at regional and global scales is essential for understanding how the Earth system operates under changing climatic conditions and for improved societal applications that range from numerical weather prediction to freshwater resource management. This session will host papers on all aspects of precipitation, especially contributions in the following four research areas: Precipitation Measurement: Precipitation measurements (amount, duration, intensity etc) by ground-based in situ sensors (e.g., rain gauges, disdrometers); estimation of accuracy of measurements, comparison of instrumentation. Precipitation Climatology: Regional and global climatology; areal distribution of measured precipitation; classification of precipitation patterns; spatial and temporal characteristics of precipitation; methodologies adopted and their uncertainties; comparative studies. Precipitation Remote Sensing: Remote sensing of precipitation (spaceborne, airborne, ground-based, underwater, or shipborne sensors); methodologies to estimate areal precipitation (interpolation, downscaling, combination of measurements and/or estimates of precipitation); methodologies used for the estimation (e.g., QPE), validation, and assessment of error and uncertainty of precipitation as estimated by remote sensors. A special focus will be on international contributions to the exploitation of the international Global Precipitation Measurement (GPM) mission that provides state-of-the-art precipitation estimates (including solid precipitation) from space with unprecedented accuracy, time-space coverage, and improved information for microphysics.
Cloud and precipitation processes are still a main source of uncertainties in numerical weather prediction and climate change projections. During recent years, large progress has been made in implementing those processes in a more realistic way and with a higher level of detail in models. Simultaneously, also our observational capabilities, especially in the field of radar remote sensing, has been substantially improved by the availability of large national networks, improved instrument accuracy, and also new and more affordable technology. Radar polarimetry in particular is known for its high information content of cloud and precipitation processes. Complementary radar observations, such as polarimetric Doppler spectra or multi-frequency cloud radar observations are also increasingly used to further extend our ability to derive characteristic fingerprints of those processes and inform atmospheric models.
This session invites contributions, which combine radar polarimetry or cloud radars with atmospheric models for an improved understanding of moist processes, numerical model evaluation, or parameterization development, as well as studies advancing the direct assimilation of polarimetric measurements or polarimetry-derived information. The combination of radar polarimetry, atmospheric modelling and data assimilation is also the focus of the German research initiative PROM (Polarimetric Radar Observations meet atmospheric Modelling). We invite contributions from all scientists working at the intersection of these fields.

Ice and mixed-phase clouds play an important role in the Earth’s radiation budget because of their high temporal and spatial coverage. Yet, the variability and complexity of their macro- and microphysical properties, the consequence of intricate ice particle nucleation and growth processes, makes their study extremely challenging. As a result, large uncertainties still exist in our understanding of ice cloud processes, their radiative effects, and their interaction with their environment (in particular, aerosols).
This session aims to advance our comprehension of ice clouds by bringing observation- and modelling-based research together.
A diversity of research topics shall be covered, highlighting recent advances in ice cloud observation techniques, modelling and subsequent process studies:
(1) Airborne, spaceborne, ground- or laboratory-based measurements and their derived products (retrievals), which are useful to constrain ice cloud properties like extent, emissivity, or crystal size distributions, to clarify formation mechanisms, and to provide climatology.
(2) Process-based, regional and global model simulations that employ observations for better representation of ice-cloud microphysical properties and radiative forcing under both current and future climate.
The synthesis of these approaches can uniquely answer questions regarding dynamical influence on ice cloud formation, life cycle, coverage, microphysical and radiative properties, crystal shapes, sizes and variability of ice particles in mixed-phase as well as ice clouds. Joint observation-modelling contributions are therefore particularly encouraged.

Mountains cover approximately one quarter of the total land surface on the planet, and a significant fraction of the world’s population lives in their vicinity. Orography critically affects weather and climate processes at all scales and, in connection with factors such as land-cover heterogeneity, is responsible for high spatial variability in mountain weather and climate. Due to this high complexity, monitoring and modeling the atmosphere and the other components of the climate system in mountain regions is challenging both at short (meteorological) and long (climatological) time-scales. This session is devoted to the better understanding of weather and climate processes in mountain and high-elevation areas around the globe, as well as their modification induced by global environmental change.
We welcome contributions describing the influence of mountains on the atmosphere on meteorological time-scales, including terrain-induced airflow, orographic precipitation, land-atmosphere exchange over mountains, forecasting and predictability of mountain weather.
Contributions connected with the TEAMx research programme (http://www.teamx-programme.org/) are encouraged.
Furthermore, we invite studies that investigate climate processes and climate change in mountain areas and its impacts on dependent systems, based on monitoring and modeling activities. Particularly welcome are contributions that merge various sources of information and reach across disciplinary borders (atmospheric, hydrological, cryospheric, ecological and social sciences) and that connect to the Elevation-Dependent Climate Change (EDCC) working group of the Mountain Research Initiative (see https://www.mountainresearchinitiative.org/activities/community-led-activities/working-groups).

Mesoscale convective systems (MCSs) and meso-scale storms/disturbances are known to be important precipitation producing/triggering systems in high-mountain environments and on high-altitude plateaus. These meso-scale convective systems and disturbances can lead to severe weather locally and affect lower lying downstream regions.
The aim of this session is to gain an improved understanding of meso-scale systems and the associated processes leading to (extreme) precipitation in mountain regions and/or their downstream areas. We invite contributions on the dynamics of meso-scale storms/disturbances and meso-scale convective systems (including their formation and evolution) as well as smaller-scale convection in connection to atmospheric meso-scale features and how these factors explain spatio-temporal patterns of precipitation and precipitation dynamics. Contributions focussing on individual extreme events or giving climatological perspectives are welcome. Due to the nature of high-mountain environments it is difficult to directly observe their meso-scale atmospheric features and link these to the occurrence and spatio-temporal variability of precipitation. Therefore, contributions integrating remote sensing data, in-situ observations, and high-resolution models, especially those that explicitly resolve convections are particularly welcome.
This session is connected to the recently launched WRCP-CORDEX flagship pilot study “High resolution climate modelling with a focus on mesoscale convective systems and associated precipitation over the Third Pole region”.

The regional monsoons and the global monsoon circulation to which they belong have profound impacts on water, energy, and food security. Monsoons cause severe floods and droughts as well as undergoing variability on subseasonal, interannual and decadal-to-multi-decadal time scales. In addition to profound local effects, monsoon variability is also associated with global-scale impacts via teleconnections.
Monsoons are among the most complex phenomena involving coupled atmosphere-ocean-land interactions and remain notoriously difficult to forecast at leads times ranging from numerical weather prediction (NWP) to long-term climate projections. A better understanding of monsoon physics and dynamics, with more accurate simulation, prediction and projection of monsoon systems is therefore of great importance.
This session invites presentations on all aspects of monsoon research in present-day, future and palaeoclimate periods, involving observations, modelling, attribution, prediction and climate projection. Topics ranging from theoretical works based on idealized planets and ITCZ frameworks to the latest field campaign results are also invited, as is work on impacts, extremes, NWP modelling, S2S and decadal forecasting, and the latest CMIP6 findings.

The polar climate system is strongly affected by interactions between the atmosphere and the cryosphere. Processes that exchange heat, moisture and momentum between land ice, sea ice and the atmosphere play an important role in local-to-global processes. Atmosphere-ice interactions are also triggered by synoptic weather phenomena such as cold air outbreaks, polar lows, atmospheric rivers and Foehn winds. However, our understanding of these processes is still incomplete. Despite being a crucial milestone for reaching accurate projections of future climate change in Polar Regions, deciphering the interplay between the atmosphere, land ice and sea ice on different spatial and temporal scales, remains a major challenge.
This session aims at showcasing recent research progress and augmenting existing knowledge in polar meteorology and climate and the atmosphere-land ice-sea ice coupling in both the Northern and Southern Hemispheres. It will provide a setting to foster discussion and help identify gaps, tools, and studies that can be designed to address these open questions. It is also the opportunity to convey newly acquired knowledge to the community.
We invite contributions on all observational and numerical modelling aspects of Arctic and Antarctic meteorology and climatology, that address atmospheric interactions with the cryosphere. This may include but is not limited to studies on past, present and future of:
- Atmospheric processes that influence sea-ice (snow on sea ice, sea ice melt, polynya formation and sea ice production) and associated feedbacks,
- The variability of the polar large-scale atmospheric circulation (such as polar jets, the circumpolar trough and storm tracks) and impact on the cryosphere (sea ice and land ice),
- Atmosphere-ice interactions triggered by synoptic and meso-scale weather phenomena such as cold air outbreaks, katabatic winds, extratropical cyclones, polar cyclones, atmospheric rivers, Foehn winds,
- Role of clouds in polar climate and impact on the land ice and sea ice through interactions with radiation,
- Teleconnections and climate indices and their role in land ice/sea ice variability.
Presentations including new observational (ground and satellite-based) and modelling methodologies specific to polar regions are encouraged. Contributions related to results from recent field campaigns in the Arctic and in the Southern Ocean/Antarctica are also welcomed.

The North Atlantic exhibits a high level of natural variability from interannual to centennial time scales, making it difficult to extract trends from observational time series. Climate models, however, predict major changes in this region, which in turn will influence sea level and climate, especially in western Europe and North America. In the last years, several observational projects have been focused on the Atlantic circulation changes, for instance ACSIS, RACE, RAPID, OSNAP, and OVIDE. Another important issue is the interaction between the atmosphere and the ocean as well as the cryosphere with the ocean, and how this affects the climate.
We welcome contributions from observers and modelers on the following topics:
-- climate relevant processes in the North Atlantic region in the atmosphere, ocean, and cryosphere
-- response of the atmosphere to changes in the North Atlantic
-- atmosphere - ocean coupling in the North Atlantic realm on time scales from years to centuries (observations, theory and coupled GCMs)
-- interpretation of observed variability in the atmosphere and the ocean in the North Atlantic sector
-- comparison of observed and simulated climate variability in the North Atlantic sector and Europe
-- dynamics of the Atlantic meridional overturning circulation
-- variability in the ocean and the atmosphere in the North Atlantic sector on a broad range of time scales
-- changes in adjacent seas related to changes in the North Atlantic
-- role of water mass transformation and circulation changes on anthropogenic carbon and other parameters
-- linkage between the observational records and proxies from the recent past

This session merges CL3.1.3 “Climate change and other drivers of environmental change: Developments, interlinkages and impacts in regional seas and coastal regions” focused on regional seas and coastal regions worldwide, and CL3.1.4 “Climate change in Mediterranean-type climate regions” focused on the Mediterranean-type climates, with a very similar scope: how climate change and other drivers affect these regions now and in the future.
Regional climate change interacts with many other man-made perturbations in both natural and anthropogenic coastal environments. Regional climate change is one of multiple drivers, which have a continuing impact on terrestrial, aquatic and socio-economic (resp. human) environments. These drivers interact with regional climate change in ways, which are not completely understood.
A Mediterranean-type climate is characterized by mild, wet winters and hot, dry summers as classified with the Koppen-Geiger approach that is well suited for identifying and analyzing the impacts of climate change on natural and anthropic ecosystems. Mediterranean climate regions (MCRs) are located in transitional midlatitude regions like the Mediterranean basin area, western coastal North America and small coastal areas of western South America, southern Africa and southern Australia. The transitional character with sharp spatial gradients makes them highly vulnerable to climate change. For all MCRs, the future holds high risks and uncertainty on issues like loss in biodiversity, increase in aridity, ecological change, requiring innovative approaches to climate adaptation and mitigation.
This session focuses on the connections and interrelations between climate change and other drivers of environmental change in MCRs, regional seas and coastal regions. It intends to strengthen the exchanges among the communities involved to better understand and share commonalities and differences and to provide an overview of the current state of knowledge of the complicated interplay of different factors affecting climate change. This exchange may help identify and prepare shared solutions and practices. Studies focused on physical (including extremes, teleconnections, hydrological cycle) and biogeochemical (including biodiversity) aspects of Mediterranean and other coastal climate regions, focusing on observed past changes, future climate projections, as well as related social aspects including indigenous knowledge in mitigating climate risks will be treated.
In his seminal work "Weather Prediction by Numerical Process" in 1922, Lewis Fry Richardson proposed his famous cascade picture qualitatively, for a turbulent flow where the energy is transferred from large scale structures to small scale ones, until reaching viscosity scales where it is converted to heat. This picture now has been widely adopted to describe different type of turbulent phenomena, for not only the classical hydrodynamic turbulence, but also, not limited to, the movement of atmosphere and oceans.
After 100 years of developments, the concept of cascades has been extended significantly. Now, it describes mainly the nonlinear interactions crossing a large range of scales where scale invariants might emerge spontaneously. More precisely, balances between the external forcing and the dissipation are expected for a turbulent system. However, due to the complexity of atmospheric or oceanic systems, such as earth rotation, stratification, large aspect ratio, mesoscale eddies, ocean current, tidal, waves, etc., the exact balance is still unknown. We still lack an efficient methodology to diagnose the scale-to-scale energy or other physical quantities fluxes to characterize the cascade quantitatively, e.g., strength, direction, etc.
With the increasing capability of remote sensing, computational fluid dynamics, field observation, etc., we have accumulated a large amount of field data. It is now a suitable time to celebrate the 100th Anniversary of Richardson's idea of cascades in the geosciences, and to understand it quantitatively.
This interdisciplinary session welcomes theoretical, methodological, laboratory, data analysis works that aim to characterize the cascade in atmosphere and oceans and other fields.

Wind and solar power are the predominant new sources of electrical power in recent years. Several countries or regions regularly exceed 100% of variable renewable energy in their grids. By their very nature, wind and solar power, as well as hydro, tidal, wave and other renewable forms of generation are dependent on weather and climate. Modelling and measurement for resource assessment, site selection, long-term and short term variability analysis and operational forecasting for horizons ranging from minutes to decades are of paramount importance.
The success of wind power means that wind turbines are increasingly put in sites with complex terrain or forests, with towers extending beyond the strict logarithmic profile, and in offshore regions that are difficult to model and measure. Major challenges for solar power are notably accurate measurements and the short-term prediction of the spatiotemporal evolution of the effects of cloud field and aerosols. Planning and meteorology challenges in Smart Cities are common for both.
For both solar and wind power, the integration of large amounts of renewable energy into the grid is another critical research problem due to the uncertainties linked to their forecast and to patterns of their spatio-temporal variabilities.
We invite contributions on all aspects of weather dependent renewable power generation, e.g.:
• Wind conditions (both resources and loads) on short and long time scales for wind power development, especially in complex environments (e.g. mountains, forests, coastal or urban).
• Inter-annual variability of solar and wind resource.
• Typical Meteorological Year and probability of exceedance for wind and solar power development.
• Wind and solar resource and atlases.
• Wake effect models and measurements, especially for large wind farms and offshore.
• Performance and uncertainties of forecasts of renewable power at different time horizons and in different external conditions.
• Forecast of extreme wind events and wind ramps.
• Local to global impacts of renewable energy power plants or of large-scale integration.
• Dedicated wind measurement techniques (SODARS, LIDARS, UAVs etc.).
• Dedicated solar measurement techniques (pyranometric sensors, sun-photometer, ceilometer, fish-eye cameras, etc.) from ground-based and space-borne remote sensing.
• Tools for urban area renewable energy supply strategic planning and control.
Other related topics will be considered by the conveners.

Heat extremes are already one of the deadliest meteorological events and they are projected to increase in intensity and frequency due to rising CO2 emissions. The hazard these events pose to society may therefore increase dramatically, and society will need to adapt if the worst impacts are to be avoided. This session therefore welcomes a broad range of new research addressing the challenge of extreme heat. Suitable contributions may: (i) assess the drivers and underlying processes of extreme heat in observations and/or models; (ii) explore the diverse socio-economic impacts of extreme heat events (for example, on aspects relating to human health or economic productivity); (iii) address forecasting of extreme heat at seasonal to sub-seasonal time scales; (iv) focus on societal adaptation to extreme heat, including the implementation of Heat-Health Early Warning Systems for disaster risk reduction.

Traditionally, hydrologists focus on the partitioning of precipitation water on the surface, into evaporation and runoff, with these fluxes being the input to their hydrologic models. However, more than half of the evaporation globally comes back as precipitation on land, ignoring an important feedback of the water cycle if the previous focus applied. Land-use and water-use changes, as well as climate variability and change alter, not only, the partitioning of water but also the atmospheric input of water as precipitation, related with this feedback, at both remote and local scales.
This session aims to:
i. investigate the remote and local atmospheric feedbacks from human interventions such as greenhouse gasses, irrigation, deforestation, and reservoirs on the water cycle, precipitation and climate, based on observations and coupled modelling approaches,
ii. investigate the use of hydroclimatic frameworks such as the Budyko framework to understand the human and climate effects on both atmospheric water input and partitioning,
iii. explore the implications of atmospheric feedbacks on the hydrologic cycle for land and water management.
Typically, studies in this session are applied studies using fundamental characteristics of the atmospheric branch of the hydrologic cycle on different scales. These fundamentals include, but are not limited to, atmospheric circulation, humidity, hydroclimate frameworks, residence times, recycling ratios, sources and sinks of atmospheric moisture, energy balance and climatic extremes. Studies may also evaluate different sources of data for atmospheric hydrology and implications for inter-comparison and meta-analysis. For example, observations networks, isotopic studies, conceptual models, Budyko-based hydro climatological assessments, back-trajectories, reanalysis and fully coupled earth system model simulations.

This session explores climate change, extremes, processes and their impacts at local to regional scales, and the tools employed to investigate these phenomena. In particular, we welcome submissions advancing the state-of-the-art in the development and application of high-resolution models (convection-permitting, grid spacing ≤ 4 km) and high-resolution sub-daily data sets. Other high-resolution data sets such as land-surface, vegetation or similar, and their impacts on local-scale climate change and extremes, are of further interest.
The session aims to bring together, amongst others, numerical modellers, the observational community and CORDEX-FPS participants, with the aim of advancing understanding of the aforementioned topics. Of particular interest are any new insights which are revealed through high-spatiotemporal-resolution modelling or data sets. For example: convective extremes, physical mechanisms, fine-scale and feedback processes, differences in climate change signal, scale-dependency of extremes, interactions across scales and land-atmosphere interactions. Further, we welcome studies that explore local-scale climate change in a variety of contexts whether they be past, present or future change.
Additional topics include, though are not limited to:
-- Mesoscale convective systems and medicanes
-- Event-based case studies (including surrogate climate change experiments or attribution)
-- Approaches for quantifying uncertainty at high resolutions including multi-model ensemble and combined dynamical-statistical approaches
-- High-resolution winds and their impacts
-- Convection, energy balance and hydrological cycle including vegetation
-- Model setup and parametrization, including sensitivity to resolution, land surface and dynamics
-- Tropical convection and convective processes at local to regional scale
-- Model evaluation and new evaluation metrics/methods
-- Physical understanding of added value over coarser models
-- Severe storms including supercell thunderstorms and hailstorms

Recent extreme weather and climate episodes, including the Canadian heatwave in 2021 and the flooding in Germany in the same summer, highlight the need to further our understanding of linear and non-linear (quasi-stationary) planetary and synoptic-scale Rossby wave dynamics in the atmosphere, and their impacts on weather and climate events.
Abstracts are solicited that are dedicated to:
(1) The dynamics of linear wave propagation or quasi-stationarity, of wave breaking, atmospheric blocking, or jets as atmospheric Rossby waveguides. This includes the role of local and remote drivers (e.g., the tropics, Arctic, or stratosphere).
(2) Exploring the links between extreme weather/climate events and linear and non-linear Rossby waves, including wave breaking and/or blocking.
(3) Quantifying model representation of Rossby waves in climate and numerical weather prediction models, including wave propagation and breaking.
(4) Exploring the role of Rossby wave packets on predictability at lead times from medium range (~2 weeks) to seasonal time-scales. This includes blocking and wave propagation.

As the societal impacts of hazardous weather and other environmental pressures grow, the need for integrated predictions which can represent the numerous feedbacks and linkages between physical and chemical atmospheric processes is greater than ever. This has led to development of a new generation of high resolution multi-scale coupled prediction tools to represent the two-way interactions between aerosols, chemical composition, meteorological processes such as radiation and cloud microphysics.
Contributions are invited on different aspects of integrated model and data assimilation development, evaluation and understanding. A number of application areas of new integrated modelling developments are expected to be considered, including:
i) improved numerical weather prediction and chemical weather forecasting with feedbacks between aerosols, chemistry and meteorology,
ii) two-way interactions between atmospheric composition and climate variability.
This session aims to share experience and best practice in integrated prediction, including:
a) strategy and framework for online integrated meteorology-chemistry modelling;
b) progress on design and development of seamless coupled prediction systems;
c) improved parameterisation of weather-composition feedbacks;
d) data assimilation developments;
e) evaluation, validation, and applications of integrated systems.
This Section is organised in cooperation with the Copernicus Atmosphere Monitoring Service (CAMS) and the WMO Global Atmosphere Watch (GAW) Programme.
This year session is dedicated to the Global Air Quality Forecasting and Information Systems (GAFIS) - an initiative of WMO and several international organizations - to enable and provide science-based air quality forecasting and information services in a globally harmonized and standardized way tailored to the needs of society.

The uncertain response of clouds to global warming is a major contributor to the spread in climate sensitivity across climate models. Cloud feedback uncertainty is related to a limited understanding of the coupling between clouds, convection and the large-scale circulation across various spatial and temporal scales. This session focuses on efforts to advance our understanding of the cloud-circulation coupling and its role in climate change. Contributions from dedicated field campaigns such as EUREC4A, from various observing platforms like ground-based and satellite remote sensing or in situ measurements, as well as modelling and theoretical studies are welcomed. We also invite abstracts focusing on the role of convective organization and precipitation in modulating the cloud-circulation coupling and cloud feedbacks.
The session is addressed to experimentalists and modellers working on air-land interactions from local to regional scales. The programme is open to a wide range of new studies in micrometeorology and related atmospheric and remote sensing disciplines. The topics include the development of new devices, measurement techniques, experimental design, data analysis methods, as well as novel findings on surface layer theory and parametrization, including local and non-local processes. The theoretical parts encompass soil-vegetation-atmosphere transport, internal boundary-layer theories and flux footprint analyses. Of special interest are synergistic studies employing experimental data, parametrizations and models. This includes energy and trace gas fluxes (inert and reactive) as well as water, carbon dioxide and other GHG fluxes. Specific focus is given to outstanding problems in land surface boundary layer descriptions such as complex terrain, effects of horizontal heterogeneity on sub-meso-scale transport processes, energy balance closure, stable stratification and night time fluxes, dynamic interactions with atmosphere, plants (in canopy and above canopy) and soils.

Land–atmosphere interactions often play a decisive role in shaping climate extremes. As climate change continues to exacerbate the occurrence of extreme events, a key challenge is to unravel how land states regulate the occurrence of droughts, heatwaves, intense precipitation and other extreme events. This session focuses on how natural and managed land surface conditions (e.g., soil moisture, soil temperature, vegetation state, surface albedo, snow or frozen soil) interact with other components of the climate system – via water, heat and carbon exchanges – and how these interactions affect the state and evolution of the atmospheric boundary layer. Moreover, emphasis is placed on the role of these interactions in alleviating or aggravating the occurrence and impacts of extreme events. We welcome studies using field measurements, remote sensing observations, theory and modelling to analyse this interplay under past, present and/or future climates and at scales ranging from local to global but with emphasis on larger scales.

Observations and model simulations illustrate significant ocean variability and associated air-sea interactions in the tropical Atlantic basin from daily-to-decadal time scales. This session is devoted to the understanding of ocean dynamics in the tropical and subtropical Atlantic Ocean, its interaction with the overlying atmosphere from the equator to the mid-latitudes and its climate impacts on adjacent to remote areas. Relevant processes in the ocean include upper and deep ocean circulation, eddies, tropical instability waves, warm pools, cold tongues and eastern boundary upwellings. We are interested in air-sea interactions related to both the seasonal cycle and the development of modes of variability from local to basin scale (e.g. the Meridional Mode, the Atlantic Niño, and the Benguela Niño). We welcome studies on wind variations related to the development of these modes, as well as studies on high-frequency events, such as marine heat waves, the Madden-Julian Oscillation, tropical cyclones and convective systems. Furthermore, we seek studies on climate change in the region, and also of the climatic impacts of change and variability on marine ecosystems. Finally, we are also interested in contributions examining the causes and impacts of systematic model errors in simulating the local to regional Atlantic climate. Studies based on direct observations, reanalysis, reconstructions as well as model simulations are welcome.

Ocean-atmosphere flux exchanges of biogeochemically active constituents have significant impacts on global biogeochemistry and climate. Increasing atmospheric deposition of anthropogenically-derived nutrients (e.g., nitrogen, phosphorus, iron) to the ocean influences marine productivity and has associated impacts on oceanic CO2 uptake, and emissions to the atmosphere of climate active species (e.g., nitrous-oxide (N2O), dimethyl-sulfide (DMS), marine organic compounds and halogenated species). Atmospheric inputs of toxic substances (e.g., lead, mercury, cadmium, copper, persistent organic pollutants) into the ocean are also of concern for their impact on ocean ecosystem health. In recent decades the intensive use of plastics has led to significant levels of persistent micro- and nano- plastics being transported into the marine atmosphere and to the ocean, with considerable uncertainty remaining on transport pathways and oceanic impacts. Other influential recent changes include emission reductions for air pollution abatement which have resulted in changes in cloud and aerosol chemical composition, affecting atmospheric acidity, associated chemical processing and impacts via atmospheric deposition on ocean biogeochemistry.
In turn, oceanic emissions of reactive species and greenhouse gases influence atmospheric chemistry and global climate, and induce potentially important chemistry-climate feedbacks. While advances have been made by laboratory, field, and modelling studies over the past decade, we still lack understanding of many of the physical and biogeochemical processes linking atmospheric deposition of chemicals, nutrient availability, marine biological productivity, trace-gas sources and sinks and the biogeochemical cycles governing air-sea fluxes of these climate active species, as well as on the atmosphere-ocean cycle of microplastics and its impact on the environment and climate.
This session will address the above issues on the atmospheric deposition of nutrients and toxic substances to the ocean, the impacts on ocean biogeochemistry, and also the ocean to atmosphere fluxes of climate active species and potential feedbacks to climate. We welcome new findings from measurement programmes (laboratory, in-situ and remote sensing) and atmospheric and oceanic numerical models.

This session welcomes submissions on new insights into the physical processes at the air-sea interface and their role in ocean-atmosphere exchange of heat, gas, momentum, freshwater, and aerosols.
Presentations based on field or satellite observations, numerical models, or theoretical contributions are welcome.
Examples of processes include solar radiation-induced diurnal warming, rain-induced cool and fresh lenses, and processes controlling the formation and properties of the surface microlayer.
Additional focus is on gustiness associated with convection in the atmospheric boundary layer and evaporative cold pools. Further focus is on air-sea interactions in polar regions, in particular related to cold air outbreaks, including the role of sea ice and the effect of leads. Air-sea interaction related to surface temperature and salinity fronts, as well as oceanic meso- and sub-mesoscale dynamics, are also of great interest. Studies considering the variability of biogeochemical properties related to air-sea processes will also be considered.

The ocean surface mixed layer mediates the transfer of heat, freshwater, momentum and trace gases between atmosphere, sea ice and ocean, thus playing a central role in the dynamics of our climate. This session will focus on the surface mixed layer globally, from the coastal ocean to the deep ocean. We will review recent progress in understanding the key dynamical and biogeochemical processes taking place in the mixed layer: surface waves, Langmuir circulations and turbulence, shear-induced mixing, internal waves, coherent structures, fronts, frontal instabilities, entrainment and detrainment at the mixed layer base, convection, restratification, dynamics of the euphotic layer, carbon and nutrient cycling, etc. The improvement of the representation of surface mixed layer processes in numerical models is a complex and pressing issue: this session will bring together new advances in the representation of mixed layer processes in high resolution numerical models, as well as evaluation of mixed layer properties in climate models using most recent observational datasets. The coupling of the ocean and atmospheric boundary layers as well as the special processes occurring under sea ice and in the marginal sea ice zone will be given special consideration. This session welcomes all contributions related to the study of the oceanic mixed layer independent of the time- and space scales considered. This includes small scale process studies, short-term forecasting of the mixed layer characteristics for operational needs, studies on the variability of the mixed layer from sub-seasonal to multi annual time scales and mixed layer response to external forcing. The use of multiple approaches (coupled numerical modeling, reanalyses, observations) is encouraged.

The rapid decline of the Arctic sea ice in the last decade is a dramatic indicator of climate change. The Arctic sea ice cover is now thinner, weaker and drifts faster. Freak heatwaves are common. On land, the permafrost is dramatically thawing, glaciers are disappearing, and forest fires are raging. The ocean is also changing: the volume of freshwater stored in the Arctic has increased as have the inputs of coastal runoff from Siberia and Greenland and the exchanges with the Atlantic and Pacific Oceans. As the global surface temperature rises, the Arctic Ocean is speculated to become seasonally ice-free by the mid 21st century, which prompts us to revisit our perceptions of the Arctic system as a whole. What could the Arctic Ocean look like in the future? How are the present changes in the Arctic going to affect and be affected by the lower latitudes? What aspects of the changing Arctic should observational, remote sensing and modelling programmes address in priority?
In this session, we invite contributions from a variety of studies on the recent past, present and future Arctic. We encourage submissions examining interactions between the ocean, atmosphere and sea ice, on emerging mechanisms and feedbacks in the Arctic and on how the Arctic influences the global ocean. Submissions taking a cross-disciplinary, system approach and focussing on emerging cryospheric, oceanic and biogeochemical processes and their links with land are particularly welcome.
The session supports the actions of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030) towards addressing challenges for sustainable development in the Arctic and its diverse regions. We aim to promote discussions on the future plans for Arctic Ocean modelling and measurement strategies, and encourages submissions on the results from IPCC CMIP and the recent observational programs, such as the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC). This session is cosponsored by the CLIVAR /CliC Northern Ocean Regional Panel (NORP) that aims to facilitate progress and identify scientific opportunities in (sub)Arctic ocean-sea-ice-atmosphere research.
Drs Karen Assmann and Wilken-Jon von Appen are the solicited speakers for the session. Karen Assmann will be presenting on physical and ecological implications of Arctic Atlantification. Wilken-Jon von Appen will be talking about eddies in the Arctic Ocean.

This session is intended to provide an interdisciplinary forum to bring together researchers working in the areas of high-latitude meteorology, atmospheric chemistry, stable isotope research, oceanography, and climate. The emphasis is on the role of boundary layer processes that mediate exchange of heat, momentum and mass between the Earth's surface (snow, sea-ice, ocean and land) and the atmosphere as well as the local to large-scale influences on these exchanges. An adequate understanding and quantification of these processes is necessary to improve modeling and prediction of future changes in the polar regions and their teleconnections with mid-latitude weather and climate, including meridional transport of heat, moisture, chemical trace species, aerosols and isotopic tracers (indicating airmass origins and atmospheric processes); and regional emission and vertical mixing of climate active trace gases and aerosol, such as cloud-forming particles (CCN/INP) and their precursors. It is expected that the recent implementation of new measurements such as those from pan-Arctic water vapor isotope networks, observations such as those obtained during the MOSAiC field program, and data from existing networks will help diagnose long-range moisture and aerosol sources and the coupling between local and large-scale dynamics. We encourage submissions such as (but not limited to):
(1) External controls on the boundary layer such as clouds, radiation and long-range transport processes
(2) Results from field programs, such as MOSAiC, and routine observatories, insights from laboratory studies, and advances in modeling and reanalysis,
(3) Use of data from pan-Arctic and Antarctic observing networks,
(4) Surface processes involving snow, sea-ice, ocean, land/atmosphere chemical and isotope exchanges, and natural aerosol sources
(5) The role of boundary layers in polar climate change and implications of climate change for surface exchange processes, especially in the context of reduced sea ice, wetter snow packs, increased glacial discharge and physical and chemical changes associated with an increasing fraction of first year ice and increasing open water.

As the most evident example of land use and land-cover change, urban areas play a fundamental role in local to large-scale planetary processes, via modification of heat, moisture, and chemical budgets. With rapid urbanization ramping up globally it is essential to recognize the consequences of landscape conversion to the built environment. Given the capability of cities to serve as first responders to global change, considerable efforts are currently being dedicated across many cities to monitor and understand urban atmospheric dynamics and examine various adaptation and mitigation strategies aimed to offset impacts of rapidly expanding urban environments and influences of large-scale greenhouse gas emissions.
This session solicits submissions from both the observational and modelling communities examining urban atmospheric and landscape dynamics, processes and impacts owing to urban-induced climate change, the efficacy of various strategies to reduce such impacts, and techniques highlighting how cities are already using novel science data and products that facilitate planning and policies on urban adaptation to and mitigation of the effects of climate change. Emerging topics including, but not limited to, compounding impacts with urban COVID-19 outbreaks, citizen science and crowdsourcing, or urban-climate informatics, are highly encouraged.

Aerosol particles are key components of the earth system important in radiative balance, human health, and other areas of key societal concern. Understanding their formation, evolution and impacts relies on developments from multiple disciplines covering both experimental laboratory work, field studies and numerical modelling. In this general session all topics of Aerosol Chemistry and Physics are covered. Contributions from aerosol laboratory, field, remote sensing and model studies are all highly encouraged.
Alongside general contributions, this year we also propose a focus on aerosols in the urban atmosphere. By the end of this century 75% of humanity will live in cities. Cities account for >80% of global carbon emissions and have begun to make ambitious commitments, including decarbonisation of multiple sectors. However, over 90% of the world’s population currently breathe dangerously polluted air, with a need to understand the sources, processes and sinks that dictate the properties of aerosol particles in urban environments and the impact they have. We thus invite submissions that fall within this topic that could include sectoral contributions, the indoor/outdoor interface, differential toxicity, projections of future climate impacts etc.

Clouds and aerosols play a key role in climate and weather-related processes over a wide range of spatial and temporal scales. An initial forcing due to changes in the aerosol concentration and composition may also be enhanced or dampened by feedback processes such as modified cloud dynamics, surface exchange or atmospheric circulation patterns. This session aims to link research activities in observations and modelling of radiative, dynamical and microphysical processes of clouds, aerosols, and their interactions. Studies addressing several aspects of the aerosol-cloud-radiation-precipitation system are encouraged. Contributions related to the EU project "Constrained aerosol forcing for improved climate projections" (FORCeS) are also invited.
Topics covered in this session include, but are not limited to:
- Cloud and aerosol macro- and microphysical properties, precipitation formation mechanisms and their role in the energy budget
- Observational constraints on aerosol-cloud interactions
- Use of observational simulators to constrain aerosols, clouds and their radiative effects in models
- Experimental cloud and aerosol studies
- High-resolution modelling, including large-eddy simulation and cloud-resolving models
- Parameterization of cloud and aerosol microphysics/dynamics/radiation processes
- Interactions between aerosols and regional circulation systems and precipitation patterns
- Aerosol, cloud and radiation interactions and feedbacks on the hydrological cycle, regional and global climate

Remote sensing of clouds and aerosols is of central importance for studying climate system processes and changes. Reliable information is required on climate-relevant parameters such as aerosol and cloud optical thickness, layer height, particle size, liquid or ice water path and vertical particulate matter columns. A number of challenges and unsolved problems remain in algorithms and their application. This includes remote sensing of clouds and aerosols with respect to 3D effects, remote sensing of polluted and mixed clouds, combination of ground-based and satellite-based systems, and the creation of long-term uniform global records. This session is aimed at the discussion of current developments, challenges and opportunities in aerosol and cloud remote sensing using active and passive remote sensing systems.

Anthropogenic aerosol plays a key role in driving climate anomalies over a range of spatial and temporal scales, both near the emission location and remotely through teleconnections. Aerosols can interact with radiation and clouds, directly and through absorption, microphysics and circulation, and thereby modify the surface and atmospheric energy balance, cloud dynamics and precipitation patterns, and the atmospheric and oceanic circulation. This session addresses progress in understanding the mechanisms and pathways by which aerosols affect regional climate features, overall, over the historical era, and in the near future. We encourage contributions on new model and observation-based approaches to investigate the effects of aerosols on regional decadal climate variability and extremes, tropical-extratropical interactions and teleconnections, and the interplay with modes of variability such as the NAO, AMV, and PDO. Focus studies on monsoon, midlatitude, and Arctic responses, extreme precipitation, circulation changes, daily variability, CMIP6 projections of high and low aerosol futures, and investigations using large ensemble simulations are welcome.

Chemistry and aerosols play a major role in determining surface air quality, the Earth’s energy budget, and climate change. Conversely, climate change affects atmospheric abundances of trace gases and aerosols through composition-climate interactions. This session focuses on global scale atmospheric chemistry and aerosol modelling, radiative forcing, and climate change through the historical period and into the future.
A better understanding of the role of natural aerosols in the atmosphere is essential for assessing climate changes. Our session explores primary aerosols and those formed from precursor gases emitted by natural sources, e.g. from wildfires, deserts, volcanoes, oceans, and vegetation. The session intends to bring together experts from different fields to assess the state-of-the-science knowledge on natural aerosols and to identify future directions to reduce uncertainty in their emissions and impacts. We encourage submissions that use models across different spatial scales and consider past, present or future perspectives, as well as measurements from remote sensing, field campaigns and laboratory experiments.
In particular, it aims to bring together scientists with an interest in:
1. Evaluating reactive gases and aerosols in models against observations
2. Quantifying the impact of emissions changes on atmospheric composition
3. Exploring chemistry-climate interactions in models, with a focus on climate feedbacks involving trace gases and aerosols
4. Quantifying radiative forcing and the climate response to changes in trace gas and aerosol concentrations
5. Distinguishing between truly natural aerosols and those whose emissions or formation are influenced by anthropogenic activities
6. Missing links in our understanding of the lifecycle of natural aerosols
7. The time evolution of contributions of natural aerosols to atmospheric composition and deposition
8. The consequences of changes in natural aerosols
The session welcomes contributions from those currently involved in analysis of recent and ongoing CMIP6 experiments focusing on the areas above,

Anthropogenic emissions of greenhouse gases and ozone depleting substances have caused substantial changes in the chemical composition of the middle atmosphere that, in turn, can influence tropospheric processes. Increasing greenhouse gas levels are expected to modify the stratospheric amount of key radiatively active gases, such as water vapor, ozone and stratospheric aerosols through changes in the stratospheric Brewer-Dobson circulation (BDC). Changes in stratospheric ozone can in turn affect the biosphere (via e.g. changes in UV exposure) and feed back on surface climate via their influence on Earth's radiative budget. In addition, long-term changes in the ozone layer (e.g. ozone hole and recovery) are known to influence the tropospheric circulation and may be further coupled to a variety of Earth system feedbacks, which are to date poorly understood.
We welcome abstracts which explore composition changes and resulting radiative impacts and feedbacks on the tropospheric and stratospheric circulation as well as on surface weather and climate. Abstracts may address these issues on time-scales encompassing inter-annual to centennial timescales as well as impacts ranging from the tropics to poles. In particular, new studies on the influence of stratospheric ozone and composition on weather and climate are of interest. Research might also concern long-term ozone trends (depletion and recovery), as well as water vapor changes and volcanic aerosol impact in the stratosphere. We welcome contributions using chemistry-climate and Earth system models such as the new Chemistry Climate Model Initiative (CCMI-2) and Coupled Model Intercomparison Project (CMIP6), observations, as well as contributions using novel statistical approaches (e.g. Machine, causal inference) to gain insights into composition changes, related feedbacks and theoretical studies.
The composition of the upper troposphere and the lower stratosphere (UTLS) plays a key role in the climate system. Our understanding of the interactions between dynamics, chemistry and climate in this region is rapidly advancing thanks to both observational and modelling studies. In this session we invite studies of dynamical, transport and chemical processes determining the variability and long-term trends in the composition of the UTLS, and related impacts on radiation and dynamics. This particularly includes studies of upper and middle stratospheric as well as of tropospheric dynamics and chemistry affecting the UTLS. We encourage studies bringing together recent in situ and/or remote sensing observations and model simulations of different complexity (e.g., comprehensive climate models, chemistry transport models, idealized and conceptual models).

The session focuses on the variability of the tropospheric and stratospheric chemical composition on the timescales from diurnal to decadal. It discusses the processes driving this variability and attribution of changes. Special emphasis is put on the scientific value of high-quality long-term measurement data sets and supporting model simulations, though the elements related to emerging data sources, measurement campaign that addresses specific processes and long-term projections of the atmospheric chemical composition are also welcome in the session. The presentations that address policy-relevant datasets on atmospheric composition are cordially invited.
Researchers are invited to present novel scientific results from mid- and long-term observational time series from various programmes and networks such as the Global Atmosphere Watch (GAW) Programme, European Monitoring, and Evaluation Programme (EMEP), Network for the Detection of Atmospheric Composition Change (NDACC), Southern Hemisphere Additional Ozonesondes (SHADOZ), Advanced Global Atmospheric Gases Experiment (AGAGE), National Oceanic and Atmospheric Administration (NOAA), regular airborne (e.g. CARIBIC, IAGOS, CONTRAIL) and other campaigns as well as satellite data and model simulations. Data relevant to tropospheric and stratospheric composition, in particular, related to ozone depletion, climate change, and air quality as well as firn data on past atmospheric composition are welcome. We welcome contributions from multi-year modeling studies and inter-comparison exercises that address past and future tropospheric or stratospheric composition changes, carried out in the framework of international projects and initiatives.

The interactions between aerosols, climate, and weather are among the large uncertainties of current atmospheric research. Mineral dust is an important natural source of aerosol with significant implications on radiation, cloud microphysics, atmospheric chemistry and the carbon cycle via the fertilization of marine and terrestrial ecosystems. In addition, properties of dust deposited in sediments and ice cores are important (paleo-)climate indicators.
This interdivisional session --building bridges between the EGU divisions CL, AS, SSP, BG and GM-- had its first edition in 2004 and it is open to contributions dealing with:
(1) measurements of all aspects of the dust cycle (emission, transport, deposition, size distribution, particle characteristics) with in situ and remote sensing techniques,
(2) numerical simulations of dust on global, regional, and local scales,
(3) meteorological conditions for dust storms, dust transport and deposition,
(4) interactions of dust with clouds and radiation,
(5) influence of dust on atmospheric chemistry,
(6) fertilization of ecosystems through dust deposition,
(7) any study using dust as a (paleo-)climate indicator, including sediment archives in loess, ice cores, lake sediments, ocean sediments and dunes.
We especially encourage the submission of papers that integrate different disciplines and/or address the modelling of past, present and future climates.

Methane is an important greenhouse gas that has contributed ∼25% of the radiative forcing experienced to date. Despite methane’s short atmospheric lifetime (~10 years), the global methane mole fraction has increased three times faster than carbon dioxide since 1750. Methane emission mitigation is an effective way to reduce the short-term rate of warming, and is essential to IPCC pathways that limit warming below 2 C. In contrast to carbon dioxide, anthropogenic methane emissions originate from a large variety and number of diffuse point sources that are mostly independent of combustion processes. As a result, systematic, international atmospheric measurements are needed to inform emission inventories and mitigation strategies.
This session will highlight field research and satellite studies that focus on methane emissions from human activities (e.g., oil and gas production, coal mining, fire, rice production, ruminants, landfills and waste). Particular emphasis is on atmospheric observations at different spatio-temporal scales with the aim to (1) reduce the uncertainty in the measured magnitude of emissions, (2) identify source-specific emission patterns and mitigation opportunities, and (3) inform government, industry, and other stakeholders on mitigation pathways.

Reactive halogen species can have an important influence on the chemistry of the troposphere. For instance, chlorine atoms react faster with most hydrocarbons than OH does and inorganic bromine and iodine can catalytically destroy tropospheric ozone and oxidise mercury. These reactions have been shown to be important in in environments as different as the polar troposphere during the springtime ozone depletion events, the boundary layer over salt lakes, and volcanic plumes. There is strong evidence that halogens play a spatially even wider role in the marine boundary layer and free troposphere for ozone destruction, changes in the ratios of OH/HO2 and NO/NO2, destruction of methane, in the oxidation of mercury and in the formation of secondary aerosol. There are indications that both, oceanic sources as well as the chemistry of halogens and volatile organic compounds (VOCs) and oxygenated VOCs (OVOCs) in the tropics are linked with potential implications not only for the photochemistry but also the formation of secondary organic aerosol (SOA). More recently, marine emissions of active halogens have been linked to potential impacts on oxidants loading in coastal cities. Finally, bromine and iodine are also being proposed as proxies of past sea ice variability.
We invite contributions in the following areas dealing with tropospheric halogens on local, regional, and global scales:
- Model studies: Investigations of the chemical mechanisms leading to release, transformation and removal of reactive halogen species in the troposphere. Studies of consequences of the presence of reactive halogen species in the troposphere.
- Laboratory studies: Determination of gas- and aqueous-phase rate constants, study of complex reaction systems involving halogens, Henry's law and uptake coefficients, UV/VIS spectra, and other properties of reactive halogen species.
- Field experiments and satellite studies: Measurements of inorganic (X, XO, HOX, XONO2, ..., X = Cl, Br, I) and organic (CH3Br, CHBr3, CH3I, RX, ...) reactive halogen species and their fluxes in the troposphere with in situ and remote sensing techniques.
- Measurements and model studies of the abundance of (reactive) halogen species in volcanic plumes and transformation processes and mechanisms.
- All aspects of tropical tropospheric halogens and links to (O)VOCs: their chemistry, sources and sinks, and their impact on local, regional, and global scales.

The session will cover all aspects of polar stratospheric ozone, other species in the polar regions as well as all aspects of polar stratospheric clouds. Special emphasis is given to results from recent polar campaigns, including observational and model studies.
We encourage contributions on chemistry, microphysics, radiation, dynamics, small and large scale transport phenomena, mesoscale processes and polar-midlatitudinal exchange. In particular, we encourage contributions on ClOx/BrOx chemistry, chlorine activation, NAT nucleation mechanisms and on transport and mixing of processed air to lower latitudes.
We welcome contributions on polar aspects of ozone/climate interactions, including empirical analyses and coupled chemistry/climate model results and coupling between tropospheric climate patterns and high latitude ozone as well as representation of the polar vortex and polar stratospheric ozone loss in global climate models.
We particularly encourage contributions from the polar airborne field campaigns as e.g. the POLSTRACC (Polar Stratosphere in a Changing Climate) and SouthTRAC (Southern Hemisphere - Transport Composition Dynamics) campaign as well as related activities, which aim at providing new scientific knowledge on the Arctic/Antarctic lowermost stratosphere and upper troposphere in a changing climate. Contributions from WMO's Global Atmosphere Watch (GAW) Programme and from the Network for the Detection of Atmospheric Composition Change (NDACC) are also encouraged.
The large uncertainty associated with regional and global anthropogenic climate change is deeply rooted in our limited understanding of molecular scale processes occurring in aerosol particles and cloud droplets, which ultimately affect cloud properties and their climate impacts via modulating particle formation and growth. Atomistic scale properties of single aerosol particles, their interactions with the surrounding vapour phase molecules as well as transport processes within the particle phase typically occur on temporal and spatial scales which are attainable only by a handful of techniques. Molecular simulations (molecular dynamics and Monte Carlo) and single molecule experiments are promising methods with uniquely high spatial and temporal resolution which can complement traditional experimental and modelling approaches. Their recent emergence as tools to characterise molecular scale properties is catalysing the development of a new interdisciplinary field at the interface of molecular modelling and aerosol science, which can help address long-standing problems in new particle formation, gas-to-particle partitioning and heterogeneous nucleation. We welcome nanoscale observations of processes involving aerosol particles that are based on experiments, molecular simulations or theoretical modelling. We solicit contributions addressing single particle properties of aerosols: single particle structure, thermodynamic properties, dynamic processes in single particles (particle formation and growth, water uptake, adsorption, ice nucleation, bulk transport phenomena, reactivity).

Atmospheric aerosol-cloud-climate interactions (e.g. heterogeneous nucleation, particle oxidation and photosensitization, molecular composition-, phase-, acidity- and structure- changes, ...) are fundamental processes in the atmosphere. Despite the importance of these processes in energy transfer, cloud dynamics, precipitation formation, and hence in climate change, little is known about the molecular mechanism and the respective contribution of different structural and chemical surface properties of the atmospheric aerosols controlling these processes in the atmosphere. For Example, ice particles in the atmosphere, both in cirrus and mixed-phase clouds, contribute to the largest uncertainty in interpretations of the Earth’s changing energy budget. Their large variability in number, size, shape, and surface properties makes it difficult to understand and parameterize their microphysical and hence radiative properties.
Fundamental understanding of the cloud dynamics and aerosol properties, which play the major role in the climate system, will require the understanding of gas-, water-, and ice-aerosol surface interactions. To advance our knowledge about atmospheric processes, this session aims to bring together two research areas, namely (1) Atmospheric Surface Science (ASS) and (2) Ice Nucleating Particles (INP):
(1) ASS is concerned with the experimental and theoretical approaches investigating atmospheric interactions as well as ice nucleation processes “on the molecular level”. The goal is to fill the gap between the large-scale atmospheric processes and gas-, water-, and ice- interactions with atmospherically relevant mineral and biological surfaces.
(2) INP are concerned with the laboratory examination, on a fundamental level, trying to understand the nucleation processes and characterizing INP in the atmosphere.

The dominant species of absorbing aerosols (AA) in the atmosphere are mineral dust (DU) and light-absorbing carbonaceous aerosols, which include black carbon (BC) and the absorbing component of organic aerosol, referred to as brown carbon (BrC). AA emissions (from deserts, biomass burning, biogenic sources, and anthropogenic activities) cover vast regions of the earth and directly modify surface fluxes, heating profiles and cloud properties. The role of AA in the earth system remains uncertain and can be attributed to all aspects of the aerosol lifetime including emission processes, optical properties, evolution, and their interaction with (and influence on) radiation, clouds, dynamics, and precipitation processes.
Reducing these uncertainties requires working across all scales, from measuring individual particles, to observing continental scale perturbations, and ultimately representing them in our earth system models. This session aims to bring together research from across all of these scales. We welcome presentations covering, but not restricted to, the following topics:
General:
• Global impacts of AA
• AA emission inventories and processes
• Regional / large-scale influences of AA
• Above-cloud impacts of AA
• Role of AA in aerosol-cloud interactions
• AA in the upper troposphere
• Global climatologies of BC, BrC, and DU
• Remote-sensing of AA
Focused:
• Ageing of all AA species: BC, BrC, and DU
• Impacts of absorption on self-lofting
• Coarse mode dust in the atmosphere and models
• Source-dependent dust optical properties
• BC ageing enhancement / mixing state / morphology in climate models
• The role of particle-to-particle variability / heterogeneity
• BrC spectral dependence
• Global constraints on BrC radiative forcing
• Absorption properties of biogenic aerosols
• Constraining absorption using observations

Over the last years, more and more satellite data on tropospheric composition have become available and are now being used in numerous applications. In this session, we aim at bringing together reports on new or improved data products and their validation as well as studies using satellite data for applications in tropospheric chemistry, emission inversions and air quality. This includes both studies on trace gases and on aerosols.
We welcome presentations based on studies analysing current and future satellite missions, in particular Sentinel 5P and GEMS, inter-comparisons of different remote sensing measurements dedicated to tropospheric chemistry sounding and/or analyses with ground-based measurements and chemical transport models.

The aim of this general session is to bring together the scientific community within air pollution modelling. The focus is ongoing research, new results and current problems related to the field of modelling the atmospheric transport and transformation on global, regional and local scales.
All presentations covering the research area of air pollution modelling are welcome, including recent model developments, applications and evaluations, physical and chemical parameterisations, process understanding, model testing, evaluation and uncertainty estimates, emissions, numerical methods, model systems and integration, forecasting, event-studies, scenarios, ensembles, assessment, etc.
This session invites contributions on the latest developments and results in lidar remote sensing of the atmosphere, covering • new lidar techniques as well as applications of lidar data for model verification and assimilation, • ground-based, airborne, and space-borne lidar systems, • unique research systems as well as networks of instruments, • lidar observations of aerosols and clouds, thermodynamic parameters and wind, and trace-gases. Atmospheric lidar technologies have shown significant progress in recent years. While, some years ago, there were only a few research systems, mostly quite complex and difficult to operate on a longer-term basis because a team of experts was continuously required for their operation, advancements in laser transmitter and receiver technologies have resulted in much more rugged systems nowadays, many of which are already operated routinely in networks and some even being automated and commercially available. Consequently, also more and more data sets with very high resolution in range and time are becoming available for atmospheric science, which makes it attractive to consider lidar data not only for case studies but also for extended model comparison statistics and data assimilation. Here, ceilometers provide not only information on the cloud bottom height but also profiles of aerosol and cloud backscatter signals. Scanning Doppler lidars extend the data to horizontal and vertical wind profiles. Raman lidars and high-spectral resolution lidars provide more details than ceilometers and measure particle extinction and backscatter coefficients at multiple wavelengths. Other Raman lidars measure water vapor mixing ratio and temperature profiles. Differential absorption lidars give profiles of absolute humidity or other trace gases (like ozone, NOx, SO2, CO2, methane etc.). Depolarization lidars provide information on the shapes of aerosol and cloud particles. In addition to instruments on the ground, lidars are operated from airborne platforms in different altitudes. Even the first space-borne missions are now in orbit while more are currently in preparation. All these aspects of lidar remote sensing in the atmosphere will be part of this session.

This session is the result of the merge of former sessions "Spectral imaging techniques for atmospheric trace gas remote sensing", and "MAX-DOAS and other scattered light DOAS systems: instruments, techniques and applications".
Shortened description of session "Spectral imaging techniques for atmospheric trace gas remote sensing":
In the last decades, concepts of atmospheric trace gas remote sensing instruments featuring imaging capability have been developed. Imaging vastly enhances the information content of atmospheric measurements and allows the determination of important parameters like f.i. mass fluxes (e.g. volcanic and ships SO2 emissions), or spatial gradients. It also offers opportunities to better grasp the context of the atmospheric measurements (e.g. cloudiness, horizon line, wind).
For the different fields of application yield various types of instruments targeting a large set of atmospheric species at a large range of spatial, temporal, and spectral resolution were developed. In response to operability requirements in the field, their handling and portability also differ.
This session aims at presenting research activities in the field of atmospheric remote sensing with a particular emphasis on measurement techniques based on spectral imaging.
Shortened description of session "MAX-DOAS and other scattered light DOAS systems: instruments, techniques and applications":
Over the last years, a growing number of Multi-AXis (MAX) and other scattered light DOAS instruments is operated world wide.
By probing the troposphere in different viewing angles and from different platforms, vertical profile information on aerosols and tropospheric trace gases, in particular NO2, can be derived.
Thereby, scattered light DOAS instruments provide an essential link between in-situ measurements of trace gas concentrations and column-integrated measurements from satellite, and thus play a key role in satellite validation.

Biogenic volatile organic compounds (bVOCs) are global chemical signatures of life. bVOCs comprise chemically diverse gaseous compounds of biological origin and are emitted from and consumed in terrestrial ecosystems. We consider biological sources and sinks being mainly plants and soil life, especially the microbiota. bVOCs are receiving an increasing scientific interest since breakthroughs in analytics of compounds but also of plants and microbiota facilitate an integrative understanding.
bVOCs have various environmental functions. Some impact on the oxidative capacity of the troposphere, stratospheric ozone destruction, and contribute to aerosol formation. Others are involved in chemical signaling between plants, animals and microbes in terrestrial ecosystems and hence, connect organisms’ activities and behaviors beyond the canonical trophic foodweb theory. In the era of the anthropocene, land use and associated human forces alter bVOC flux dynamics by changing ecosystems and their properties.
Understanding bVOCs fluxes in and from terrestrial ecosystems has two conceptual dimensions. (a) They are ecological interaction signals and thus, are affecting ecological interactions and ecosystem functioning - which includes plant production in agriculture - and (b) they are relevant for atmospheric chemistry and thus land-atmosphere interactions. Both dimensions are inherently intertwined and can be seen as two sides of the same coin.
We would like to merge both dimensions in one single session at the EGU Biogeosciences Division to trigger discussions on future research perspectives - e.g. how to quantitatively determine and/or predict bVOC fluxes by considering interactions of biological actors. Also novel insights in the topic, and methodological developments and new approaches are highly welcomed.
Over the last decades, Earth’s atmospheric composition has been extensively monitored from space using different techniques and spectral ranges. The GOME (Global Ozone Monitoring Experiment) instrument launched in 1995 by ESA showed that atmospheric space missions can not only be used for ozone monitoring but also to measure a range of trace gases for air quality and climate monitoring. Several decades after these pioneering efforts, continuous progress in instrument design, and retrieval techniques allows now operational monitoring of stratospheric and tropospheric concentrations of a wide range of trace gas species with implications for air quality and climate. This has been well demonstrated with the successful operations of the Sentinel-5 Precursor (S-5P) satellite since 2018.
S-5P is the first of a series of atmospheric missions within the European Commission’s Copernicus Programme and provides continuity in the availability of global atmospheric data products between its predecessor missions SCIAMACHY (Envisat) and OMI (AURA) and the future Copernicus Sentinel-4 and -5 satellite series. The current/future European (Copernicus) atmospheric measurement capabilities are/will be complimented by other space missions like MetOp, MetOp-SG, SUOMI-NPP, GOSAT/2, TanSat, GaoFen 5, OCO2/3, TEMPO, GEMS and others.
This session will include latest results on S-5P operational products usage (e.g. COVID-19 impact monitoring, detection of emission hot spots), results of algorithm studies to develop additional S5-P products (e.g. bromine monoxide, water vapour, glyoxal, AOD, SIF, chlorophyll, and chlorine dioxide) and their geophysical validation. Synergistic data usage or intercomparison results of S-5P measurements with con-current flying missions (e.g. MetOp, GOSAT) and algorithm studies for future mission retrieval algorithms (e.g. Sentinel-4/5) will be addressed. Opportunities that new instrument concepts can bring to the atmospheric air quality and climate monitoring communities will be included as well.
A correct characterization of atmospheric transport is crucial for the understanding of environmental challenges such as acid rain, ozone depletion, and climate change. However, there are still significant gaps in our knowledge. The impacts of the recent large wildfires, the role of the atmosphere for the spread of microplastic particles, the transport of biological material such as bacteria, viruses, pollen, and fungal spores are topics of increasing concern. In additions, transport of dust, greenhouse gases, classical pollutants, and ozone-depleting substances continues to be an active research area.
For a realistic characterization of the atmospheric composition, the connection between local and global scales often plays an important role and present challenges for models, as well as the correct reconstruction of anthropogenic and natural emission. In this context, Lagrangian models, more robust with respect to scales, represent an important tool and find applications for many practical purposes including volcanic eruptions, nuclear accidents and extreme pollution events. In addition, in combination with observations, inverse modelling techniques can be used to assess emission sources, which are generally poorly constrained.
Similarly, the development of models with respect to numerical issues and parameterization of processes, such as dry and wet deposition for various kinds of trace substances, is ongoing. Case studies can help to estimate how good models perform and enable tuning of those parametrizations.
Contributions are therefore invited for the following topics:
• Applications of Lagrangian atmospheric transport models.
• Interpretation of measurements of atmospheric trace substances using atmospheric transport modelling, including novel applications such as biological or microplastic materials.
• Studies combining observations and models to infer information about emissions or transport characteristics.
• New developments and improvements in atmospheric transport modelling, including the improvement of parameterization of atmospheric processes, the quantitative assessment of uncertainties, improving model performance, and the proper coupling of Lagrangian models to Eulerian Numerical Weather Prediction and General Circulation models.
Managed agricultural ecosystems (grassland and cropland) are an important source and/or sink for various gases in the atmosphere including greenhouse gases (GHG) and reactive trace gases like ammonia. Due to the simultaneous influence of various environmental drivers and management activities (e.g. fertilizer application, harvest, grazing) the flux patterns are often complex and difficult to attribute to individual drivers.
While process-based models are designed to combine all relevant effects on gas emissions, some processes like denitrification (as a source of N2 and N2O) have rarely been validated due to the lack of suitable data-sets, and thus results of their application on site and regional scales are still highly uncertain.
The session addresses experimentalists and modelers working on carbon and nitrogen cycling processes and related gas fluxes on plot, field, landscape, and regional scale.
We invite contributions from the following fields: methodical advances in measuring and modelling of soil processes; measurements of gas fluxes under field or field-like conditions with a focus on controlling factors; method comparisons including micrometeorological and chamber techniques as well as tracer and isotope (or isotopologue) approaches or other novel methods; process-based modelling at various scales; and the linking of soil processes and emissions to microbial community parameters.
Fire is an essential feature of terrestrial ecosystems and an important component of the Earth system. Climate, vegetation, and human activity regulate fire occurrence and spread, but fires also feedback to them in multiple ways. This session welcomes contributions that explore the role of fire in the Earth system at any temporal and spatial scale using modeling, field and laboratory observations, proxy-records, and/or remote sensing. We encourage all abstracts that advance our understanding on interactions between fire and (1) weather, climate, as well as atmospheric chemistry and circulation, (2) biogeochemical, energy, and water cycles, (3) vegetation composition and structure, (4) pyrogenic carbon, including effects on soil functioning and soil organic matter dynamics, (5) cryosphere (e.g. permafrost, sea ice), and (6) humans (e.g., impact of fire on air and water quality, freshwater resources, human health, land use and land cover change, fire management). We also welcome contributions focusing on fire characterization, including (7) fire behavior and emissions (e.g. fire duration, emission factors, emission height, smoke transport), (8) spatial and temporal changes of fire regimes in the past, present, and future, (9) fire products and models, and their validation, error/bias assessment and correction, and (10) analytical tools designed to enhance situational awareness among fire practitioners and early warning systems.

The Fagradalsfjall eruption on the Reykjanes Peninsula of Iceland started on 19 March 2021. It provides a unique opportunity to study all aspects of a low-intensity effusive basaltic eruption in great detail using multidisciplinary approaches. The Fagradalsfjall eruption followed a several-week long period of intense seismicity and deformation associated with formation of the feeding dike. The eruption terminated on September 18, 2021, after producing a lava field covering about 4.5 km2. The eruption progressed through several phases, each characterized by different emission sources, eruptive style, intensities, and associated hazards. The eruption may be representative of the formation of a shield volcano, a process that the scientific community has had limited chances to observe in real time.
We welcome submissions on sustained low-intensity basaltic eruptions including (but not limited to) the 2021 Fagradalsfjall eruption; their plumbling systems, eruptive products, and impacts. We particularly encourage comparative studies across different regions that may help us to better understand the volcanic processes that are active in the Fagradalsfjall eruption.
Topics may include, for example: physical volcanology of eruptive products and eruptive behavior; lava flow modeling; acoustic studies; petrology; geochemistry and interaction with groundwater; studies of volcanic gases; crustal deformation; seismology; volcano monitoring; social effects; health effects; hazard mitigation; tectonic implications; volcano-tectonic interactions; atmosphere-climate interactions, etc.

Cosmic rays carry information about space and solar activity, and, once near the Earth, they produce isotopes, influence genetic information, and are extraordinarily sensitive to water. Given the vast spectrum of interactions of cosmic rays with matter in different parts of the Earth and other planets, cosmic-ray research ranges from studies of the solar system to the history of the Earth, and from health and security issues to hydrology and climate change.
Although research on cosmic-ray particles is connected to a variety of disciplines and applications, they all share similar questions and problems regarding the physics of detection, modeling, and the influence of environmental factors.
The session brings together scientists from all fields of research that are related to monitoring and modeling of cosmogenic radiation. It will allow sharing of expertise amongst international researchers as well as showcase recent advancements in their field. The session aims to stimulate discussions about how individual disciplines can share their knowledge and benefit from each other.
We solicit contributions related but not limited to:
- Health, security, and radiation protection: cosmic-ray dosimetry on Earth and its dependence on environmental and atmospheric factors
- Planetary space science: satellite and ground-based neutron and gamma-ray sensors to detect water and soil constituents
- Neutron and Muon monitors: detection of high-energy cosmic-ray variations and its dependence on local, atmospheric, and magnetospheric factors
- Hydrology and climate change: low-energy neutron sensing to measure water in reservoirs at and near the land surface, such as soils, snow pack, and vegetation
- Cosmogenic nuclides: as tracers of atmospheric circulation and mixing; as a tool in archaeology or glaciology for dating of ice and measuring ablation rates; and as a tool for surface exposure dating and measuring rates of surficial geological processes
- Detector design: technological advancements for the detection of cosmic rays
- Cosmic-ray modeling: advances in modeling of the cosmic-ray propagation through the magnetosphere and atmosphere, and their response to the Earth's surface
- Impact modeling: How can cosmic-ray monitoring support environmental models, weather and climate forecasting, irrigation management, and the assessment of natural hazards

The session gathers geoscientific aspects such as dynamics, reactions, and environmental/health consequences of radioactive materials that are massively released accidentally (e.g., Chernobyl and Fukushima nuclear power plant accidents, wide fires, etc.) and by other human activities (e.g., nuclear tests).
The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Thus, the radioactive contamination problem is multi-disciplinary. In fact, this topic involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic and ecosystem, and its relations with human and non-human biota. The topic also involves hazard prediction and nowcast technology.
By combining 35 years (> halftime of Cesium 137) monitoring data after the Chernobyl Accident in 1986, 10 years dense measurement data by the most advanced instrumentation after the Fukushima Accident in 2011, and other events, we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents.
The following specific topics have traditionally been discussed:
(a) Atmospheric Science (emissions, transport, deposition, pollution);
(b) Hydrology (transport in surface and ground water system, soil-water interactions);
(c) Oceanology (transport, bio-system interaction);
(d) Soil System (transport, chemical interaction, transfer to organic system);
(e) Forestry;
(f) Natural Hazards (warning systems, health risk assessments, geophysical variability);
(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).
The session consists of updated observations, new theoretical developments including simulations, and improved methods or tools which could improve observation and prediction capabilities during eventual future nuclear emergencies. New evaluations of existing tools, past nuclear contamination events and other data sets also welcome.

Natural radioactivity is ubiquitous in the environment as a result of i) cosmic radiation from space and secondary radiation from the interaction of cosmic rays with the atmosphere, ii) terrestrial sources from soils and rocks and particularly Potassium, Uranium and Thorium and their decay products among which Radon gas stands out. Artificial radionuclides from nuclear and radiation accidents and incidents makes up an additional contribution to the environmental radioactivity.
Nuclear techniques enable the measurement of radioactivity in air, soils and water even at trace levels, making it a particularly appealing tool for tracing time-varying environmental phenomena. This session welcomes contributions addressing the measurement and exploitation of environmental radioactivity in all areas of geosciences, including, but not limited to:
- geological and geomorphological surveys;
- mineral exploration;
- groundwater contamination;
- coastal and marine monitoring;
- soil erosion processes;
- Naturally Occurring Radioactive Materials (NORMs);
- geostatistical methods for radioactivity mapping;
- airborne and drones surveys;
- novel methods and instrumentations;
- atmospheric tracing, mixing and transport processes;
- public health including the EU BSS directive and Euratom-Drinking Water Directive

The virus is still with us, with more potent variants. It remains the most immediate challenge for geosciences and health, including its impacts on geoscience development (data collection, training, dissemination) and the achievement of the UN Sustainable Development Goals, in particular that urban systems should increase well-being and health.
Long-term visions based on transdisciplinary scientific advances are therefore essential. As a consequence, this session, like the ITS1.1 session in 2021, calls for contributions based on data-driven and theory-based approaches to health in the context of global change. This includes :
- main lessons from lockdowns?
- how to get the best scientific results during a corona pandemic?
- how to manage field works, geophysical monitoring and planetary missions?
- qualitative improvements in epidemic modelling, with nonlinear, stochastic, and complex system science approaches;
- eventual interactions between weather and/or climate factors and epidemic/health problems
- new surveillance capabilities (including contact tracing), data access, assimilation and multidimensional analysis techniques;
- a fundamental revision of our urban systems, their greening and their need for mobility;
- a special focus on urban biodiversity, especially to better manage virus vectors;
- urban resilience must include resilience to epidemics, and therefore requires revisions of urban governance.

High-impact climate and weather events typically result from the interaction of multiple hazards across various spatial and temporal scales. These events, also known as Compound Events, often cause more severe socio-economic impacts than single-hazard events, rendering traditional univariate extreme event analyses and risk assessment techniques insufficient. It is therefore crucial to develop new methodologies that account for the possible interaction of multiple physical drivers when analysing high-impact events. Such an endeavour requires (i) a deeper understanding of the interplay of mechanisms causing Compound Events and (ii) an evaluation of the performance of climate/weather, statistical and impact models in representing Compound Events.
The European COST Action DAMOCLES coordinates these efforts by building a research network consisting of climate scientists, impact modellers, statisticians, and stakeholders. This session creates a platform for this network and acts as an introduction of the work related to DAMOCLES to the research community.
We invite papers studying all aspects of Compound Events, which might relate to (but are not limited to) the following topics:
Synthesis and Analysis: What are common features for different classes of Compound Events? Which climate variables need to be assessed jointly in order to address related impacts? How much is currently known about the dependence between these variables?
Stakeholders and science-user interface: Which events are most relevant for stakeholders? What are novel approaches to ensure continuous stakeholder engagement?
Impacts: What are the currently available sources of impact data? How can they be used to link observed impacts to climate and weather events?
Statistical approaches, model development and evaluation: What are possible novel statistical models that could be applied in the assessment of Compound Events?
Realistic model simulations of events: What are the physical mechanisms behind different types of Compound Events? What type of interactions result in the joint impact of the hazards that are involved in the event? How do these interactions influence risk assessment analyses?

With recent extreme events reaching far beyond existing records, such as the Pacific Northwest heat wave and severe flooding in Western Europe, eastern US and across China, the discussion to what extent we are prepared for unprecedented extremes and whether existing methods and models are able to capture them has flared up. It is becoming increasingly essential to understand and quantify plausible rare, high-impact events for risk management and adaptation.
Methods to understand and evaluate low-likelihood extreme events have seen substantial advancements over the recent years. Event attribution studies are now providing rapid analyses of unprecedented extreme events; physical climate storylines are developed to evaluate plausible rather than likely events; causal inference is used to understand drivers of very rare events; near-miss events and potential analogues in space, historical and paleo archives are evaluated; spatial extreme value analysis and machine learning methods are applied, large ensembles representing various outcomes are generated, such as Single Model Initial-condition Large Ensembles (SMILEs); and weather prediction systems are increasingly being employed, such as the through the UNprecedented Simulated Extremes using ENsembles (UNSEEN) approach.
This session aims to bring together communities from weather prediction, climate projection, hydrology to impact and risk management, and to learn from the variety of methods to understand and quantify low-likelihood extreme events in the present and future climate. The session welcomes contributions at all temporal and spatial scales, and all types of extremes and invites novel methods – including downward counterfactuals and causal inference – as well as new results on unforeseen climate risks – including those from compound events and low-likelihood high-warming outcomes.

Lightning is the energetic manifestation of electrical breakdown in the atmosphere, occurring as a result of charge separation processes operating on micro and macro-scales, leading to strong electric fields within thunderstorms. Lightning is associated with tropical storms and severe weather, torrential rains and flash floods. It has significant effects on various atmospheric layers and drives the fair-weather electric field. It is a strong indicator of convective processes on regional and global scales, potentially associated with climate change. Thunderstorms and lightning are also associated with the production of energetic radiation up to tens of MeV on time scales from sub-millisecond (Terrestrial Gamma-ray Flashes) to tens of seconds (gamma-ray glows).
This session seeks contributions from research in atmospheric electricity with emphasis on:
Atmospheric electricity in fair weather and the global electrical circuit
Effects of dust and volcanic ash on atmospheric electricity
Thunderstorm dynamics and microphysics
Middle atmospheric Transient Luminous Events
Energetic radiation from thunderstorms and lightning
Experimental investigations of lightning discharge physics processes
Remote sensing of lightning and related phenomena by space-based sensors
Thunderstorms, flash floods, tropical storms and severe weather
Modeling of thunderstorms and lightning
Now-casting and forecasting of thunderstorms using machine learning and AI
Regional and global lightning detection networks

With global climate change affecting the frequency and severity of extreme meteorological and hydrological events, it is particularly necessary to develop models and methodologies for a better understanding and forecasting of present-day weather induced hazards. Future changes in the event characteristics as well as changes in vulnerability and exposure are among the further factors for determining risks for infrastructure and society, and for the development of suitable adaptation measures. This session considers extreme events that lead to disastrous hazards induced by severe weather and climate change. These can, e.g., be tropical or extratropical rain- and wind-storms, hail, tornadoes or lightning events, but also (toxic) floods, long-lasting periods of drought, periods of extremely high or of extremely low temperatures, etc. Papers are sought which contribute to the understanding of their occurrence (conditions and meteorological development), to assessment of their risk (economic losses, infrastructural damages, human fatalities, pollution), and their future changes, to the ability of models to reproduce them and methods to forecast them or produce early warnings, to proactive planning focusing on damage prevention and damage reduction. In order to understand fundamental processes, papers are also encouraged that look at complex extreme events produced by combinations or sequences of factors that are not extreme by themselves. The session serves as a forum for the interdisciplinary exchange of research approaches and results, involving meteorology, hydrology, environmental effects, hazard management and applications like insurance issues.
The heliosphere is permeated with energetic particles of different compositions, energy spectra and origins. Two major populations of these particles are galactic cosmic rays (GCRs), which originate from outside of the heliosphere and are constantly detected at Earth, and solar energetic particles (SEPs) which are accelerated at/near the Sun during solar flares or by shock fronts associated with the transit of coronal mass ejections. Enhancements in energetic particle fluxes at Earth pose a hazard to humans and technology in space and at high altitudes. Within the magnetosphere, energetic particles are present in the radiation belts, and particle precipitation is responsible for the aurora and for hazards to satellites. Energetic particles have also been shown to cause changes is the chemistry of the middle and upper atmosphere, thermodynamic effects in the upper troposphere and lower stratosphere region, and can influence components of the global electric circuit. This session will aim to address the transport of energetic particles through the heliosphere, their detection at Earth and the effects they have on the terrestrial atmosphere when they arrive. It will bring together scientists from several fields of research in what is now very much an interdisciplinary area. The session will allow sharing of expertise amongst international researchers as well as showcase the recent advances being made in this field, which demonstrate the importance of the study of these energetic particle populations.

Soils sustain complex patterns of life and act as biogeochemical reactors producing and consuming a large amount of gas molecules. They play a fundamental role in the temporal evolution of the atmospheric gases concentration (greenhouse gases, biogenic volatile organic compounds, nitrous acid, isotopic composition…) and they modulate the soil pore gas concentrations affecting many soil functions, such as root and plant growth, microbial activity, and stabilization of soil organic carbon. Gases production, consumption and transport in the different soil types have then some important ecological implications for the earth system.
The factors affecting the soil gas processes range from physical soil structure (porosity, granulometry,…), type and amount of living material (microbiota, root systems), soil chemistry properties (carbon and nitrogen contents, pH,…) and soil meteorological conditions (temperature, water content,…). A large mixing of different scientific backgrounds are therefore required to improve the knowledge about their influence which is made even more difficult due to the very large spatial heterogeneity of these factors and the complexity of their interactions.
This session will be the place to present and exchange about the measurement techniques, data analyses and modelling approaches that can help to figure out the temporal and spatial variability of the production/consumption and transport of gases in soils. In addition to mechanisms related to carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), including the geochemical ones, the abstracts about volatile carbon compounds produced by plant and microbial or Helium and Radon geogenic emissions production are welcome
A special attention will be given to the researches including special water situations as edaphic drought or waterlogged soils

The 2021-2022 Hunga Tonga-Hunga Ha'apai eruption in Tonga was among the largest of recent decades. The event was notable for its high intensity, generating a convective column that rapidly ascended well into the stratosphere; for the atmospheric pressure wave generated by the explosion, which was detected globally; and for generating a tsunami that was observable across Pacific Ocean shorelines. Following a series of preceding seismic and explosive events since December 2021, the sustained phase of the eruption on 15th January was relatively short lived, but the associated pressure wave and tsunami impacts were the most far-reaching since the eruption of Krakatau volcano in 1883. Tsunamis were recorded both locally and in the far-field, but their mechanism(s) remains uncertain; in the near field being from either (or both of) the collapsing eruption column or a phreatomagmatic explosion as the erupting mass mixed with sea water. In the far-field the tsunamis are possibly best explained by the massive atmospheric pressure wave, that is the first instrumentally recorded eruption-generated event of its type, which affected the entire global atmosphere and ionosphere, causing the observed infrasound waves and unusual long-period seismic resonances.
This interdisciplinary late-breaking session welcomes contributions from all disciplines involved in local and global observations of this eruption and its effects, including remote sensing observations and modeling as well as hazard assessment and estimation of damage and long-term consequences.
Unsupervised, supervised, semi-supervised as well as reinforcement learning are now increasingly used to address Earth system related challenges.
Machine learning could help extract information from numerous Earth System data, such as in-situ and satellite observations, as well as improve model fidelity through novel parameterisations or speed-ups. This session invites submissions spanning modelling and observational approaches towards providing an overview of the state-of-the-art of application of these novel methods for predicting and monitoring our earth system. This includes (but it is not restricted to):
- the use of machine learning to improve forecast skill
- generate significant speedups
- design new parameterization schemes
- emulate numerical models.
Please consider submitting abstracts focussed on ML applied to observations and modelling of climate processes to the companion "ML for Climate Science" session.
Recent developments in machine learning (ML) are transforming Earth observation data analysis and modelling of the Earth system and its constituent processes. While statistical models have been used for a long time, state-of-the-art machine and deep learning algorithms allow encoding non-linear, spatio-temporal relationships robustly without sacrificing interpretability. These advances have the potential to accelerate climate science by improving our understanding of the underlying processes, reducing and better quantifying uncertainty, and even making predictions directly from observations across different spatio-temporal scales.
This session aims to provide a venue to present the latest progress in the use of ML applied to all aspects of climate science including, but not limited to:
- Causal discovery and inference
- Learning (causal) process and feature representations in observations
- Hybrid models (physically informed ML)
- Novel detection and attribution approaches
- Probabilistic modelling and uncertainty quantification
- Explainable AI applications to climate science
Please consider submitting abstracts focussed on ML for model improvement, particularly for near-term (including seasonal) forecasting to the companion “ML for Earth System modelling” session.
Instrumentation and its development play a key role in advancing research, providing state-of-the-art tools to address scientific "open questions" and to enable novel fields of research leading to new discoveries.
Over the last several decades, atmospheric environmental monitoring has benefited from the development of novel spectroscopic measurement techniques owing to the significant breakthroughs in photonic technology from the UV to Microwave spectral regions. These advances open new research avenues for observation of spatial and long-term trends in key atmospheric precursors, thus improving our understanding of tropospheric chemical processes and trends that affect regional air quality and global climate change. Extensive development of spectroscopic instruments for sensing the atmosphere continues toward improving performance and functionality, and reducing size and cost.
This focus session entitled "Advanced Spectroscopic Measurement Techniques for Atmospheric Science" addresses the latest developments and advances in a broad range of spectroscopic instrumentation and photonic/optoelectronic devices and technologies, and their integration for a variety of atmospheric applications. The objective is to provide a platform for sharing information on state-of-the-art and emerging developments in photonic instrumentation for atmospheric sensing. This interdis¬ciplinary forum aims to foster discussion among experimentalists, atmospheric scientists, and development engineers. It is also an opportunity for R&D and analytical equipment companies to evaluate the capabilities of new instrumentation and techniques.
Topics for presentation include novel spectroscopic methods and instruments for measuring atmospheric aerosols, isotopologues, trace gases and radicals. In situ and remote observations, vertical concentration profiles, and flux measurements are all welcome. Spectroscopic methods could include high performance absorption spectroscopy (such as broadband and laser-based cavity-enhanced spectroscopies and multipass systems, and other high-sensitivity spectroscopic methods), fluorescence techniques, heterodyne radiometry, and aerosol spectroscopy. Applications to field observations, airborne platforms (UAV, balloon, aircraft), geological exploration, and smog chamber studies are welcome. Creative approaches using new photonic technologies, methodologies, and data analysis tools are particularly encouraged.
Rainfall is a “collective” phenomenon emerging from numerous drops. Understanding the relation between the physics of individual drops and that of a population of drops remains an open challenge, both scientifically and at the level of practical implications. This remains true also for solid precipitation. Hence, it is much needed to better understand small scale spatio-temporal precipitation variability, which is a key driving force of the hydrological response, especially in highly heterogeneous areas (mountains, cities). This hydrological response at the catchment scale is the result of the interplay between the space-time variability of precipitation, the catchment geomorphological / pedological / ecological characteristics and antecedent hydrological conditions. Therefore, (1) accurate measurement and prediction of the spatial and temporal distribution of precipitation over a catchment and (2) the efficient and appropriate description of the catchment properties are important issues in hydrology.
This session will bring together scientists and practitioners who aim to measure and understand precipitation variability from drop scale to catchment scale as well as its hydrological consequences. Contributions addressing one or several of the following topics are especially targeted:
- Novel techniques for measuring liquid and solid precipitation variability at hydrologically relevant space and time scales (from drop to catchment scale), from in situ measurements to remote sensing techniques, and from ground-based devices to spaceborne platforms. Innovative comparison metrics are welcomed;
- Precipitation drop (or particle) size distribution and its small scale variability, including its consequences for precipitation rate retrieval algorithms for radars, commercial microwave links and other remote sensors;
- Novel modelling or characterization tools of precipitation variability from drop scale to catchment scale from various approaches (e.g. scaling, (multi-)fractal, statistic, deterministic, numerical modelling);
- Novel approaches to better identify, understand and simulate the dominant microphysical processes at work in liquid and solid precipitation.
- Applications of measured and/or modelled precipitation fields in catchment hydrological models for the purpose of process understanding or predicting hydrological response.

Observations from aircraft, remotely piloted aircraft systems (RPAS/UAV/UAS) and balloons are an important means to obtain a broad view of processes within the Earth environment during measurement campaigns. The range of available instruments enables a broad and flexible range of applications. It includes sensors for meteorological parameters, trace gases and cloud/aerosol particles and more complex systems like high spectral resolution lidar, hyperspectral imaging at wavelengths from the visible to thermal infra-red, solar-induced fluorescence and synthetic aperture radar. The use of small state-of-the-art instruments, the combination of more and more complex sets of instruments with improved accuracy and data acquisition speed enables more complex campaign strategies even on small aircraft, balloons or RPAS.
Applications include atmospheric parameters, structural and functional properties of vegetation, glaciological processes, sea ice and iceberg studies, soil and minerals and dissolved or suspended matter in inland water and the ocean. Ground based systems and satellites are key information sources to complement airborne datasets and a comprehensive view of the observed system is often obtained by combining all three. Aircraft and balloon operations depend on weather conditions either to obtain the atmospheric phenomenon of interest or the required surface-viewing conditions and so require detailed planning. They provide large horizontal and vertical coverage with adaptable temporal sampling. Future satellite instruments can be tested using airborne platforms during their development. The validation of operational satellite systems and applications using airborne measurements has come increasingly into focus with the European Copernicus program in recent years.
This session will bring together aircraft, balloon and RPAS operators and researchers to present:
• an overview of the current status of environmental research focusing on the use of airborne platforms
• recent observation campaigns and their outcomes
• multi-aircraft/balloon/RPAS and multi-RI campaigns
• using airborne and ground-based RI to complement satellite data, including cal/val campaigns
• identifying and closing capability gaps
• contributions of airborne measurements to modelling activities
• airborne platforms to reduce the environmental footprint of alternative observation strategies
• airborne instruments, developments and observations
• future plans involving airborne research

Environmental systems often span spatial and temporal scales covering different orders of magnitude. The session is oriented toward collecting studies relevant to understand multiscale aspects of these systems and in proposing adequate multi-platform and inter-disciplinary surveillance networks monitoring tools systems. It is especially aimed to emphasize the interaction between environmental processes occurring at different scales. In particular, special attention is devoted to the studies focused on the development of new techniques and integrated instrumentation for multiscale monitoring of high natural risk areas, such as volcanic, seismic, energy exploitation, slope instability, floods, coastal instability, climate changes, and another environmental context.
We expect contributions derived from several disciplines, such as applied geophysics, geology, seismology, geodesy, geochemistry, remote and proximal sensing, volcanology, geotechnical, soil science, marine geology, oceanography, climatology, and meteorology. In this context, the contributions in analytical and numerical modeling of geological and environmental processes are also expected.
Finally, we stress that the inter-disciplinary studies that highlight the multiscale properties of natural processes analyzed and monitored by using several methodologies are welcome.

The Open Session on atmosphere, land and ocean monitoring aims at presenting highlights of recent results obtained through observations and modelling as well as relevant reviews in these fields.
We shall connect with Earth Observations programmes at ESA, EU and worldwide, using new satellites and oberving platforms, as well as new techniques for distributing, merging and analysing EO data using AI.
The session is intended as an open forum for interdisciplinary discussion between representatives of different fields. Thus, we welcome especially overarching presentations which may be interesting to a wider community.
Observations are one major link to get an overall picture of processes within the Earth environment during measurement campaigns. This includes application to derive atmospheric parameters, surface properties of vegetation, soil and minerals and dissolved or suspended matter in inland water and the ocean. Ground based systems and data sets from ships, aircraft and satellites are key information sources to complement the overall view. All of these systems have their pros and cons, but a comprehensive view of the observed system is generally best obtained by means of a combination of all of them.
The validation of operational satellite systems and applications is a topic that has come increasingly into focus with the European Copernicus program in recent years. The development of smaller state-of-the-art instruments, the combination of more and more complex sets of instruments simultaneously on one platform, with improved accuracy and high data acquisition speed together with high accuracy navigation and inertial measurements enables more complex campaign strategies even on smaller aircraft or unmanned aerial vehicles (UAV).
This session will bring together a multidisciplinary research community to present:
• Atmosphere-land-ocean (or inland water) system modelling and validation
• new instruments (Lidar, etc), platforms (UAV etc.), setups and use in multidisciplinary approaches
• Larger scale in-situ and remote sensing observation networks from various platforms (ground based, airborne, ship-borne, satellite)
• recent field campaigns and their outcomes
• (multi-) aircraft campaigns
• satellite calibration/validation campaigns
• sophisticated instrument setups and observations
• advanced instrument developments
• UAV applications

This session is open to contributions from diverse fields where stable isotopes of light elements (e.g. C, H, O, N) and other novel tracers, such as carbonyl sulfide, clumped isotopes and non-mass dependent fractionation processes are used to identify and quantify biological, chemical and physical processes. We welcome contributions from field and laboratory experiments, the latest instrument developments as well as theoretical and modelling studies.
Topics addressed in this session include:
- Stable isotopes of carbon dioxide (CO2), water (H2O), methane (CH4), nitrous oxide (N2O), carbonyl sulfide (COS) and any other trace gases
- Novel tracers and biological analogues, such as COS
- Polyisotopocules ("clumped isotopes")
- Intramolecular stable isotope distributions ("isotopomer abundances")
- Analytical, method and modelling developments

Geodesy contributes to atmospheric science by providing some of the essential climate variables of the Global Climate Observing System. Water Vapor (WV) is currently under-sampled in meteorological and climate observing systems. Obtaining more high-quality humidity observations is essential to weather forecasting and climate monitoring. The production, exploitation and evaluation of operational GNSS-Met for weather forecasting is well established in Europe due to 20+ years of cooperation between the geodetic community and the national meteorological services. Improving the skill of numerical weather prediction (NWP) models to forecast extreme precipitation requires GNSS products with a higher spatio-temporal resolution and shorter turnaround. Homogeneously reprocessed GNSS data (e.g., IGS repro3) have high potential for monitoring water vapor climatic trends and variability. With shortening orbit repeat periods, SAR measurements are a new source of information to improve NWP models. Using NWP data within real-time (RT) GNSS data analysis can initialize PPP algorithms, thus shortening convergence times and improving positioning. GNSS signals can be used for L-band remote sensing when Earth-surface reflected signals are considered. GNSS-R contributes to environmental monitoring with estimates of soil moisture, snow depth, ocean wind speed, sea ice concentration and has the potential to be used to retrieve near-surface WV.
We welcome, but not limit, contributions on:
•Estimates of the neutral atmosphere using ground- and space-based geodetic data and the use thereof in weather forecasting and climate monitoring
•Retrieval and comparison of tropospheric parameters from multi-GNSS, VLBI, DORIS and multi-sensor observations
•Now-casting, forecasting, and climate research using RT and reprocessed tropospheric products, employing numerical weather prediction and machine learning
•Assimilation of GNSS tropospheric products in NWP and in climate reanalysis
•Production of SAR tropospheric parameters and assimilation thereof in NWP
•Homogenization of long-term GNSS and VLBI tropospheric products
•Delay properties of GNSS signals for propagation experiments
•Exploitation of NWP data in GNSS data processing
•Techniques for soil moisture retrieval from GNSS data and for ground-atmosphere boundary interactions
•Detection and characterization of sea level, snow depth and sea ice changes, using GNSS-R
•Studying the atmospheric water cycle employing satellite gravimetry.

Networking is crucial for scientists of all career stages for collaborations as well as for their personal growth and career pathways. Your scientific network can support you when struggling with everyday academic life, help with making career choices and give feedback on job applications/proposals/papers. Further, having a scientific network can provide new perspectives for your research while leading to interdisciplinary collaborations and new projects.
Building up an initial network can be challenging, especially outside of your research institution. As scientific conferences and social media platforms are evolving, the possibilities of academic networking are also changing. In this short course we will share tips and tricks on how to build, grow and maintain your scientific network. Additionally, panelist will talk about their own personal experiences. In a second part of the short course we will do a networking exercise. This short course is relevant to scientist who are starting to build/grow their network or want to learn more about networking in today’s scientific settings.

After the PhD, a new challenge begins: finding a position where you can continue your research or a
job outside academia where you can apply your advanced skills. This task is not
always easy, and frequently a general overview of the available positions is missing. Furthermore,
in some divisions, up to 70% of PhD graduates will go into work outside of academia. There are many
different careers which require or benefit from a research background. But often, students and
early career scientists struggle to make the transition due to reduced support and networking.
In this panel discussion, scientists with a range of backgrounds give their advice on where to find
jobs, how to transition between academia and industry and what are the pros and cons of a career
inside and outside of academia.
In the final section of the short course, a Q+A will provide the audience with a chance to ask
their questions to the panel. This panel discussion is aimed at early career scientists but anyone
with an interest in a change of career will find it useful. An extension of this short course will
run in the networking and early career scientist lounge, for further in-depth or
one-on-one questions with panel members.

Finding funds can be challenging in academia, be it during PhD, or after that. A great proposal or just a great idea does not guarantee success, instead, it involves developing skills and exploring the paths which can lead to securing funds. It involves meticulous steps of evolving idea, proposal development, budget generation, and finally finding funding opportunities. In this course, early-career scientists, and faculty members with a wide range of backgrounds will provide guidance both in the research, and financial aspects of the proposal writing. The course is integrated with open Q&A which will provide participants to ask and seek advice from the experts. This course targets a wide range of audience ranging from graduate students to early-career scientists, but anyone with an interest in finding funds could participate

Visualisation of scientific data is an integral part of scientific understanding and communication. Scientists have to make decisions about the most effective way to communicate their results everyday. How do we best visualise the data to understand it ourselves? How do we best visualise our results to communicate with others? Common pitfalls can be overcrowding, overcomplicated plot types or inaccessible color schemes. Scientists may also get overwhelmed by the graphics requirements of different publishers, for presentations, posters etc. This short course is designed to help scientists improve their data visualization skills in a way that the research outputs would be more accessible within their own scientific community and reach a wider audience.
Topics discussed include:
- Choosing a plot type – keeping it simple
- Color schemes – which ones to use or not to use
- Creativity vs simplicity – finding the right balance
- Producing your figures – software and tools
- Figure files – publication ready resolutions
This course is organized by the Young Hydrologic Society (YHS), enabling networking and skill enhancement of early career researchers worldwide. Our goal is to help you make your figures more accessible by a wider audience, informative and beautiful. If you feel your graphs are complicated or not intuitive, we welcome you to join this short course.

Observations and measurements of geophysical systems and dynamical phenomena are obtained as time series or spatio-temporal data whose dynamics usually manifests a nonlinear multiscale (in terms of time and space) behavior. During the past decades, nonlinear approaches in geosciences have rapidly developed to gain novel insights on weather and climate dynamics, fluid dynamics, on turbulence and stochastic behaviors, on the development of chaos in dynamical systems, and on concepts of networks, nowadays frequently employed in geosciences.
In this short course, we will offer a broad overview of the development and application of nonlinear concepts across the geosciences in terms of recent successful applications from various fields, ranging from climate to near-Earth space physics. The focus will be on a comparison between different methods to investigate various aspects of both known and unknown physical processes, moving from past accomplishments to future challenges.

The climate system as a whole can be viewed as a highly complex thermal/heat engine, in which numerous processes continuously interact to transform heat into work and vice-versa. As any physical system, the climate system obeys the basic laws of thermodynamics, and we may therefore expect the tools of non-equilibrium thermodynamics to be particularly useful in describing and synthesising its properties. The main aim of this short course will be twofold. Part 1 will provide an advanced introduction to the fundamentals of equilibrium and non-equilibrium thermodynamics, irreversible processes and energetics of multicomponent stratified fluids. Part 2 will illustrate the usefulness of this viewpoint to summarize the main features of the climate system in terms of thermodynamic cycles, as well as a diagnostic tool to constrain the behavior of climate models. Although the aim is for this to be a self-contained module, some basic knowledge of the subject would be beneficial to the participants.
- The first part, chaired by Remi Tailleux, will provide an advanced introduction on the fundamentals of equilibrium and non-equilibrium thermodynamics, irreversible processes and energetics.
- The second part, chaired by Valerio Lembo and Gabriele Messori, will illustrate some applications of thermodynamics to the study of the climate system and its general circulation.

The short course will be structured as such: - Part 1 (45 mins): theoretical background, by Remi Tailleux;
- Short break (5 mins);
- Part 2 (15 mins): diagnosing thermodynamics in climate models, by Valerio Lembo;

On 9 August 2021, the Intergovernmental Panel on Climate Change (IPCC) released the first volume of its 6th Assessment Report (AR6). The Working Group I contribution to the Report (Climate Change 2021: The Physical Science Basis) synthesises over 14,000 publications and represents the most comprehensive and up-to-date assessment of the climate system and climate change. Crucially, the Report highlights the unprecedented and potentially irreversible influence of anthropogenic climate forcing, and for the first time, explicitly states that human influence on the climate system is unequivocal.
This short course will be a panel discussion where authors and contributors of Working Group I unpack how the IPCC 6th Assessment Report (AR6) is produced, provide personal behind-the-scenes insight on its development, and discuss its global impact, including how it is used to inform policy. Authors of the report will share their experiences of working on the report before and through the COVID pandemic. Panelists will also emphasise various ways in which scientists of all career stages can contribute to the IPCC process. Ample time will be allocated for open discussion for the audience to ask related questions to the panelists.
For more information about the AR6 please visit the IPCC website: https://www.ipcc.ch/.
Fire is an essential feature of terrestrial ecosystems and an important component of the Earth system. Climate, vegetation, and human activity regulate fire occurrence and spread, but fires also feedback to them in multiple ways. This session welcomes contributions that explore the role of fire in the Earth system at any temporal and spatial scale using modeling, field and laboratory observations, proxy-records, and/or remote sensing. We encourage all abstracts that advance our understanding on interactions between fire and (1) weather, climate, as well as atmospheric chemistry and circulation, (2) biogeochemical, energy, and water cycles, (3) vegetation composition and structure, (4) pyrogenic carbon, including effects on soil functioning and soil organic matter dynamics, (5) cryosphere (e.g. permafrost, sea ice), and (6) humans (e.g., impact of fire on air and water quality, freshwater resources, human health, land use and land cover change, fire management). We also welcome contributions focusing on fire characterization, including (7) fire behavior and emissions (e.g. fire duration, emission factors, emission height, smoke transport), (8) spatial and temporal changes of fire regimes in the past, present, and future, (9) fire products and models, and their validation, error/bias assessment and correction, and (10) analytical tools designed to enhance situational awareness among fire practitioners and early warning systems.

Anthropogenic disturbance of the global nitrogen (N) cycle has more than doubled the amount of reactive N circulating in the terrestrial biosphere alone. Exchange of reactive/non-reactive nitrogen gases between land and atmosphere are strongly affecting Earth’s atmospheric composition, air quality, global warming, climate change and human health. This session seeks to improve our understanding of a) how intensification of reactive N use, land management and climate change affects the pools and fluxes of N in terrestrial and aquatic ecosystems, and b) how reactive N enrichment of land and water will affect the future carbon sink of natural ecosystems as well as atmospheric exchanges of reactive (NH3, N2O, NOx, HONO) and non-reactive N (N2) gases with implications for global warming, climate change and air quality. We welcome contributions covering a wide range of experimental and modelling studies, which cover microbe-mediated and physico-chemical transformations and transport of nitrogen across the land-water-air continuum in natural and managed ecosystems from local to regional and global scales. Furthermore, the session will explore interactions of N with other element cycles (e.g. those of phosphorus and carbon) and highlight the impacts for soil health, biodiversity and water and air quality. Latest developments in methodological and observational approaches for unravelling the complexities of N transformations and transport are of particular interest.

The Amazon forest is the world’s largest intact forest landscape. Due to its large biodiversity, carbon storage capacity, and role in the hydrological cycle, it is an extraordinary interdisciplinary natural laboratory of global significance. In the Amazon rain forest biome, it is possible to study atmospheric composition and processes, biogeochemical cycling and energy fluxes at the geo-, bio-, atmosphere interface under near-pristine conditions for a part of the year, and under anthropogenic disturbance of varying intensity the rest of the year. Understanding its current functioning at process up to biome level in its pristine and degraded state is elemental for predicting its response upon changing climate and land use, and the impact this will have on local up to global scale.
This session aims at bringing together scientists who investigate the functioning of the Amazon and comparable forest landscapes across spatial and temporal scales by means of remote and in-situ observational, modelling, and theoretical studies. Particularly welcome are also presentations of novel, interdisciplinary approaches and techniques that bear the potential of paving the way for a paradigm shift.

Redox sensitive elements (RSE) are generally found in higher concentrations (compared to their detrital levels) within the sediments deposited in oxygen depleted environments. Although modern ocean waters are well oxygenated, with oxygen deprived settings occurring in isolated basins and high-productivity zones, oxygen-depleted environments were dominating through early Earth’s history. The degree of RSE enrichments in ancient sediments reflects the sedimentary environment that was oxygen-poor. However, we are still lacking tools for more precise description of ancient environments implying need for more extensive interdisciplinary research on mechanism of RSE accumulation in anoxic sediments. In order to understand fully RSE behaviour in anoxic settings one needs to have comprehensive understanding of the overall “chemistry behind”, not only in anoxic environments. This session presents new contributions on RSE present-day investigation in the environment using different techniques (mass spectrometry, isotopic analysis, elemental speciation, solid phase characterization, radiochemical methods) in settings (lakes, rivers, ocean) characterized with different oxygen concentration and oxygen penetration depth in water column and/or sediment, respectively. We encourage contributions using interdisciplinary and multi-analytical approaches targeting description of the RSE sedimentary phases, RSE speciation in aqueous phase, RSE cycling at the oxia/anoxia boundary, i.e., in general research leading towards better understanding of the (bio)geochemistry of RSE.

Mercury (Hg) is a toxic global pollutant of great environmental concern. Anthropogenic activities have altered the global Hg cycle to a great extent and many ecosystems are threatened by exposure to elevated levels of Hg and its different species. For instance, neurotoxic and bioaccumulating methyl-Hg is formed under the influence of anaerobic microorganisms in a variety of natural systems but the controls on this key process are still far from being understood. Further active Hg research areas include exchange processes at the atmosphere-soil-plant interface and their importance for understanding atmospheric Hg deposition, the behavior and long-term fate of Hg at contaminated sites, as well as global cycling models assessing the evolution of historic Hg fluxes from different natural and anthropogenic sources. Recently, a number of novel research tools based on microbiological, spectroscopic, isotopic, and modelling techniques have been developed to improve our understanding of Hg cycling in the environment. This session presents new contributions on present-day Hg cycling in the environment using field-based, experimental, and/or modelling approaches on local to global scales, as well as contributions focusing on long- and short-term reconstruction of Hg as a pollutant over time using natural archives such as ice-cores, tree-rings, lake sediments and peat bogs. We particularly welcome research addressing the effects of global change on Hg cycling as well as the implementation of the Minamata convention on mercury levels in the environment and new approaches to assess its effectiveness.

The Earth’s subsurface hosts enormous methane volumes trapped in geologic reservoirs, gas hydrates and permafrost, locally escaping the sediment at cold seeps to enter the hydrosphere/atmosphere.
Such environments are highly sensitive to climate change. Despite an increasing awareness about the positive feedback between global warming and methane seepage, the response of these complex and dynamic systems to climate change is still unclear due to complex geo/hydro/atmosphere interactions.
Fossil cold seeps, long-term observatory studies and modern examples form the foundations to understand the mutual dependences between climate and seepage, and to develop robust models to forecast future scenarios at the Earth-system scale. For this session, we welcome geologists, geophysicists, geochemists, biologists, model developers, and any others who have contributed to new case studies in modern and fossil hydrocarbon seeps in the marine and terrestrial environment, gas hydrate and permafrost settings, to describe both new methods/technologies and the scientific outcomes.
The session gathers geoscientific aspects such as dynamics, reactions, and environmental/health consequences of radioactive materials that are massively released accidentally (e.g., Chernobyl and Fukushima nuclear power plant accidents, wide fires, etc.) and by other human activities (e.g., nuclear tests).
The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Thus, the radioactive contamination problem is multi-disciplinary. In fact, this topic involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic and ecosystem, and its relations with human and non-human biota. The topic also involves hazard prediction and nowcast technology.
By combining 35 years (> halftime of Cesium 137) monitoring data after the Chernobyl Accident in 1986, 10 years dense measurement data by the most advanced instrumentation after the Fukushima Accident in 2011, and other events, we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents.
The following specific topics have traditionally been discussed:
(a) Atmospheric Science (emissions, transport, deposition, pollution);
(b) Hydrology (transport in surface and ground water system, soil-water interactions);
(c) Oceanology (transport, bio-system interaction);
(d) Soil System (transport, chemical interaction, transfer to organic system);
(e) Forestry;
(f) Natural Hazards (warning systems, health risk assessments, geophysical variability);
(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).
The session consists of updated observations, new theoretical developments including simulations, and improved methods or tools which could improve observation and prediction capabilities during eventual future nuclear emergencies. New evaluations of existing tools, past nuclear contamination events and other data sets also welcome.

This session merges CL3.1.3 “Climate change and other drivers of environmental change: Developments, interlinkages and impacts in regional seas and coastal regions” focused on regional seas and coastal regions worldwide, and CL3.1.4 “Climate change in Mediterranean-type climate regions” focused on the Mediterranean-type climates, with a very similar scope: how climate change and other drivers affect these regions now and in the future.
Regional climate change interacts with many other man-made perturbations in both natural and anthropogenic coastal environments. Regional climate change is one of multiple drivers, which have a continuing impact on terrestrial, aquatic and socio-economic (resp. human) environments. These drivers interact with regional climate change in ways, which are not completely understood.
A Mediterranean-type climate is characterized by mild, wet winters and hot, dry summers as classified with the Koppen-Geiger approach that is well suited for identifying and analyzing the impacts of climate change on natural and anthropic ecosystems. Mediterranean climate regions (MCRs) are located in transitional midlatitude regions like the Mediterranean basin area, western coastal North America and small coastal areas of western South America, southern Africa and southern Australia. The transitional character with sharp spatial gradients makes them highly vulnerable to climate change. For all MCRs, the future holds high risks and uncertainty on issues like loss in biodiversity, increase in aridity, ecological change, requiring innovative approaches to climate adaptation and mitigation.
This session focuses on the connections and interrelations between climate change and other drivers of environmental change in MCRs, regional seas and coastal regions. It intends to strengthen the exchanges among the communities involved to better understand and share commonalities and differences and to provide an overview of the current state of knowledge of the complicated interplay of different factors affecting climate change. This exchange may help identify and prepare shared solutions and practices. Studies focused on physical (including extremes, teleconnections, hydrological cycle) and biogeochemical (including biodiversity) aspects of Mediterranean and other coastal climate regions, focusing on observed past changes, future climate projections, as well as related social aspects including indigenous knowledge in mitigating climate risks will be treated.
The interactions between aerosols, climate, and weather are among the large uncertainties of current atmospheric research. Mineral dust is an important natural source of aerosol with significant implications on radiation, cloud microphysics, atmospheric chemistry and the carbon cycle via the fertilization of marine and terrestrial ecosystems. In addition, properties of dust deposited in sediments and ice cores are important (paleo-)climate indicators.
This interdivisional session --building bridges between the EGU divisions CL, AS, SSP, BG and GM-- had its first edition in 2004 and it is open to contributions dealing with:
(1) measurements of all aspects of the dust cycle (emission, transport, deposition, size distribution, particle characteristics) with in situ and remote sensing techniques,
(2) numerical simulations of dust on global, regional, and local scales,
(3) meteorological conditions for dust storms, dust transport and deposition,
(4) interactions of dust with clouds and radiation,
(5) influence of dust on atmospheric chemistry,
(6) fertilization of ecosystems through dust deposition,
(7) any study using dust as a (paleo-)climate indicator, including sediment archives in loess, ice cores, lake sediments, ocean sediments and dunes.
We especially encourage the submission of papers that integrate different disciplines and/or address the modelling of past, present and future climates.

Biogeomorphology addresses the two-way interaction between abiotic and biotic elements that shape landscapes at various spatio-temporal scales. Yet, developing theory, methods and quantifying processes across the abiotic/biotic interface remains challenging. This is partly due to the interdisciplinarity of biogeomorphology, integrating concepts from biology, climatology, engineering, Earth surface science and geology (amongst other disciplines). Although more and more biogeomorphic feedbacks are being investigated, understood, and applied in practice, many of these remain poorly studied and understood. However, a better understanding of abiotic-biotic interaction across scales is urgently needed for a more holistic understanding of the Earth surface as well as ecological dynamics for sustainable management, and climate change mitigation and adaptation.
This session aims to bring together geoscientists, soil scientists and biologists working at different spatial and temporal scales on how climate, tectonics, soils, flora and fauna affect landscape development, erosion control and thus form the Earth’s surface. Thus, we provide a discussion platform for all aspects of biogeomorphology, including fundamental science and applied studies. Topics may include, but are not limited to, biogeomorphic processes, rates and feedbacks for biotic and/or abiotic processes, climate-tectonics-earth surface dynamics, and biogeomorphology as a tool to sustainably manage natural systems and hazards. We encourage everyone interested in biogeomorphology to contribute to the session to further strengthen the community and stimulate discussion and collaboration across scales.

Observations from aircraft, remotely piloted aircraft systems (RPAS/UAV/UAS) and balloons are an important means to obtain a broad view of processes within the Earth environment during measurement campaigns. The range of available instruments enables a broad and flexible range of applications. It includes sensors for meteorological parameters, trace gases and cloud/aerosol particles and more complex systems like high spectral resolution lidar, hyperspectral imaging at wavelengths from the visible to thermal infra-red, solar-induced fluorescence and synthetic aperture radar. The use of small state-of-the-art instruments, the combination of more and more complex sets of instruments with improved accuracy and data acquisition speed enables more complex campaign strategies even on small aircraft, balloons or RPAS.
Applications include atmospheric parameters, structural and functional properties of vegetation, glaciological processes, sea ice and iceberg studies, soil and minerals and dissolved or suspended matter in inland water and the ocean. Ground based systems and satellites are key information sources to complement airborne datasets and a comprehensive view of the observed system is often obtained by combining all three. Aircraft and balloon operations depend on weather conditions either to obtain the atmospheric phenomenon of interest or the required surface-viewing conditions and so require detailed planning. They provide large horizontal and vertical coverage with adaptable temporal sampling. Future satellite instruments can be tested using airborne platforms during their development. The validation of operational satellite systems and applications using airborne measurements has come increasingly into focus with the European Copernicus program in recent years.
This session will bring together aircraft, balloon and RPAS operators and researchers to present:
• an overview of the current status of environmental research focusing on the use of airborne platforms
• recent observation campaigns and their outcomes
• multi-aircraft/balloon/RPAS and multi-RI campaigns
• using airborne and ground-based RI to complement satellite data, including cal/val campaigns
• identifying and closing capability gaps
• contributions of airborne measurements to modelling activities
• airborne platforms to reduce the environmental footprint of alternative observation strategies
• airborne instruments, developments and observations
• future plans involving airborne research

Soil organic matter (SOM) contains a vast range of diverse organic structures, and also a living component (microorganisms) with various residence times that define the central role SOM plays in fundamental physico-chemical and biological processes in the soil. With human activities severely affecting SOM dynamics (through inappropriate agricultural practices, erosion, forest fires, climate change), a better understanding of SOM transformation is urgently needed as this has further implications for carbon (C), nitrogen (N) and phosphorus (P) cycling and biogeochemical processes affecting global CO2 emissions. Detailed analyses of SOM composition can highlight the role of selective preservation mechanisms and sources of SOM, for example, and how these are modified and influenced by physical and chemical interactions.
To trace SOM sources and the composition of microbial communities a broad set of biomarkers is used: lignin compounds (C sources from plant communities), cutin and suberin (above- vs belowground plant biomass), non-cellulose sugars (plant vs microbial C), DNA (microbial community composition), phospholipid fatty acids (living microbial groups), ergosterol (fungal biomass), amino sugars (microbial necromass and its sources) are just a few examples. Coupling analysis of these biomarkers with 13C/14C/15N/33P/18O labeling allows tracing these elements through the microbial food web and the soil element cycles. It, thus, reveals turnover of organics and their stabilization in SOM, C, N and P recycling in microbial biomass, growth rates of bacteria and fungi, and microbial metabolic pathways.
We encourage the submission of studies (especially from early-career students) employing new methods or applications of identification and quantification of biomarkers to study: i) the fate and turnover of organic and inorganic inputs in soil (from uptake and utilization by microorganisms to stabilization in SOM), ii) the mechanisms and sources of SOM formation and its turnover, and iii) to link microbial recycling of different elements (C, N and, P) from fresh organic material or during reworking SOM. Field and laboratory studies focused on the effects of management practices, climate change, environmental conditions, soil properties are highly welcome. We also encourage contributors to present and discuss analytical challenges that remain due to environmental and analytical uncertainty.

Soil pollution is a worldwide problem, which can result in a negative impact in (terrestrial) ecosystems, surface and groundwater, and the food chain. According to the European Commission, there are around 2.8 million soil pollution events contributing to soil pollution. Of these, 25 % have been identified and registered, but only 5% need mitigation strategies. In order to address soil pollution and develop preventive and mitigation strategies, it is necessary to invest in (i) the identification and characterization of these sites, from contaminant identification to ecosystem characterisation, and (ii) the identification of potential solutions. This requires linking new strategies (e.g. machine learning, artificial intelligence, digital data mapping) with natural solutions (e.g. soil-microorganisms-root-plant interaction). We welcome our colleagues to present their latest and ongoing findings and look forward to establishing new partnerships to create holist strategies that can help to prevent, assess and mitigate soil pollution consistently and swiftly.
This interdisciplinary session welcomes contributions on novel conceptual and/or methodological approaches and methods for the analysis and statistical-dynamical modeling of observational as well as model time series from all geoscientific disciplines.
Methods to be discussed include, but are not limited to linear and nonlinear methods of time series analysis. time-frequency methods, statistical inference for nonlinear time series, including empirical inference of causal linkages from multivariate data, nonlinear statistical decomposition and related techniques for multivariate and spatio-temporal data, nonlinear correlation analysis and synchronisation, surrogate data techniques, filtering approaches and nonlinear methods of noise reduction, artificial intelligence and machine learning based analysis and prediction for univariate and multivariate time series.
Contributions on methodological developments and applications to problems across all geoscientific disciplines are equally encouraged. We particularly aim at fostering a transfer of new methodological data analysis and modeling concepts among different fields of the geosciences.

Meet editors of internationally renowned journals in geo- and biogeoscience and gain exclusive insights into the publishing process. After a short introduction into some basics, we will start exploring various facets of academic publishing with short talks given by the editors on
- What are the duties and roles of editors, authors and reviewers?
- How to choose a suitable journal for your manuscript and what is important for early career authors?
- How can early career scientists get involved in successful peer-reviewing?
- What is important for appropriate peer-reviewing?
- What are ethical aspects and responsibilities of publishing?
Together with the audience and the editors, we will have an open discussion of the key steps and factors shaping the publication process of a manuscript. This short course aims to provide early career scientists across several EGU divisions (e.g. AS, BG, CL, GM, NH, SSP and SSS) the opportunity of using first hand answers of experienced editors of international journals to successfully publish their manuscripts and get aware of the potentials and pitfalls in academic publishing.

Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

Recent advances in image collection, e.g. using unoccupied aerial vehicles (UAVs), and topographic measurements, e.g. using terrestrial or airborne LiDAR, are providing an unprecedented insight into landscape and process characterization in geosciences. In parallel, historical data including terrestrial, aerial, and satellite photos as well as historical digital elevation models (DEMs), can extend high-resolution time series and offer exciting potential to distinguish anthropogenic from natural causes of environmental change and to reconstruct the long-term evolution of the surface from local to regional scale.
For both historic and contemporary scenarios, the rise of techniques with ‘structure from motion’ (SfM) processing has democratized data processing and offers a new measurement paradigm to geoscientists. Photogrammetric and remote sensing data are now available on spatial scales from millimetres to kilometres and over durations of single events to lasting time series (e.g. from sub-second to decadal-duration time-lapse), allowing the evaluation of event magnitude and frequency interrelationships.
The session welcomes contributions from a broad range of geoscience disciplines such as geomorphology, cryosphere, volcanology, hydrology, bio-geosciences, and geology, addressing methodological and applied studies. Our goal is to create a diversified and interdisciplinary session to explore the potential, limitations, and challenges of topographic and orthoimage datasets for the reconstruction and interpretation of past and present 2D and 3D changes in different environments and processes. We further encourage contributions describing workflows that optimize data acquisition and processing to guarantee acceptable accuracies and to automate data application (e.g. geomorphic feature detection and tracking), and field-based experimental studies using novel multi-instrument and multi-scale methodologies. This session invites contributions on the state of the art and the latest developments in i) modern photogrammetric and topographic measurements, ii) remote sensing techniques as well as applications, iii) time-series processing and analysis, and iv) modelling and data processing tools, for instance, using machine learning approaches.
The main goal of this short course is to provide an introduction into the basic concepts of numerical modelling of solid Earth processes in the Earth’s crust and mantle in a non-technical manner. We discuss the building blocks of a numerical code and how to set up a model to study geodynamic problems. Emphasis is put on best practices and their implementations including code verification, model validation, internal consistency checks, and software and data management.
The short course introduces the following topics:
(1) The physical model, including the conservation and constitutive equations
(2) The numerical model, including numerical methods, discretisation, and kinematical descriptions
(3) Code verification, including benchmarking
(4) Model design, including modelling philosophies
(5) Model validation and subsequent analysis
(6) Communication of modelling results and effective software, data, and resource management
Armed with the knowledge of a typical numerical modelling workflow, participants will be better able to critically assess geodynamic numerical modelling papers and know how to start with numerical modelling.
This short course is run by early career geodynamicists. It is aimed at everyone who is interested in, but not necessarily experienced with, geodynamic numerical models; in particular early career scientists (BSc, MSc, PhD students and postdocs) and people who are new to the field of geodynamic modelling.

Within this course, the attendees are taught how to identify possible cyclicities in paleoclimate data (e.g., sediments, speleothems) or any other geological record. We will start from the basics of which data can be analysed, go over power spectra, and discuss the application of filters and Wavelet Analysis. We will discuss the advantages and disadvantages of different methods, and give some examples from Earth Sciences to highlight common pitfalls. The aim of this course is to give a brief overview of the most common techniques and give participants the insight to prepare and analyse their data themselves. A variety of computational platforms are available for time-series analysis. In this course, we will introduce different tools and techniques by making use of the programming language R.

Research, especially for early career scientists (ECS), starts with the spark of an idea and is then often challenged by empirical or methodological road bumps and seemingly dead ends. In Earth Science research, we face a diverse range of challenges, including (1) access difficulties, whether for field sites, equipment or data, (2) problems of temporal and spatial scaling and extrapolation and (3) a lack of methods, theory or knowledge or (4) every day live challenges as a scientist. As part of SC4 we want to address some of those 'problems'. In the discussion of these challenges we seek to find possible solutions, suggest new research approaches and methods, and encourage further networking amongst early career scientists at future international conferences.
We will start the session at this year's hybrid meeting with 2 minute ‘pop-up’ presentations outlining some challenges. These pop-ups are followed by chaired and structured outbreak group discussions. There will be the option to join these discussions both in-person and virtually. To wrap up the session, solutions and suggestions from each group are presented to the whole session in a final discussion. This short course lives by your input, so participants are expected to actively engage to crowd solve the presented challenges. To ensure that people are able to have a safe and open space to share their ideas, we ask you to join for the whole session. You can get an idea of past crowd-solving sessions, both in-person and online, from our 2019 (EGU blog) and 2021 (EGU blog) blog posts, see links below.
If you have a 'problem' you would like to discuss in the networking session with us, please send a short statement (3-4 sentences) of your idea or challenge and your motivation for solving it to us, by March 1st, 2022. We expect a non-hierarchic, respectful and constructive environment for the discussions, which will hopefully encourage the participants to identify and approach problems faced by early-career scientists.
During the recent years, it has become more and more obvious that soil structure plays a fundamental role in regulating processes in soils. As soil structures are hierarchical, complex and highly variable, studies involving soil structures require a relatively large number of replicate samples. Three-dimensional X-ray imaging provides an excellent tool to map out soil structure, but image analyses are still time intensive and require experience. This limits the number of X-ray images, and thus replicate samples that can be analyzed within reasonable time scales. SoilJ is an open-source and free plugin for the open-source image processing software ImageJ. It is tailor-made for the analyses X-ray images of soil and aims at automatizing the necessary image processing and analyses steps. This course gives a short introduction into X-ray image processing and analyses in general and specifically with SoilJ, provides an overview about SoilJ functionalities and offers guidance for researchers interested in participating in developing their own plugins.

Plant traits extend the range of earth observations to the level of individual organisms, providing a link to ecosystem function and modelling in the context of rapid global changes. However, overcoming the differences in temporal and spatial scales between plant trait data and biogeochemical cycles remains a challenge.
This session will address the role of plant traits, biodiversity, acclimation, and adaptation in the biogeochemical cycles of water, carbon, nitrogen, and phosphorus. We welcome conceptual, observational, experimental and modelling approaches and studies from the local to the global scale, including in-situ or remote sensing observations.

The terrestrial vegetation carbon balance is controlled not just by photosynthesis, but by respiration, carbon allocation, turnover (comprising litterfall, background mortality and disturbances) and wider vegetation dynamics. Observed, and likely future, changes in vegetation structure and functioning are the result of interactions of these processes with atmospheric carbon dioxide concentration, climate and human activities. The quantification and assessment of such changes has proven extremely challenging because of a lack of observations at large scales and over the long time periods required to evaluate trends.
Thus, our current understanding of the environmental controls on vegetation dynamics and properties, and, in turn, their impact on carbon stocks in biomass and soils, is limited. The behaviour of vegetation models regarding many of the processes mentioned above remains under-constrained at scales from landscape to global. This gives rise to high uncertainty as to whether the terrestrial vegetation will continue to act as a carbon sink under future environmental changes, or whether increases in autotrophic respiration or carbon turnover might counteract this negative feedback to climate change. For instance, accelerated background tree mortality or more frequent and more severe disturbance events (e.g. drought, fire, insect outbreaks) might turn vegetation into carbon sources. Likewise, understanding how these shifts in dynamics will influence forest composition is crucial for long-term carbon cycle projections.
Uncertainties and/or data gaps in large-scale empirical products of vegetation dynamics, carbon fluxes and stocks may be overcome by extensive collections of field data and new satellite retrievals of forest biomass and other vegetation properties. Such novel datasets may be used to evaluate, develop and parametrize global vegetation models and hence to constrain present and future simulations of vegetation dynamics. Where no observations exist, exploratory modelling can investigate realistic responses and identify necessary measurements. We welcome contributions that make use of observational approaches, vegetation models, or model-data integration techniques to advance understanding of the effects of environmental change on vegetation dynamics, tree mortality and carbon stocks and fluxes at local, regional or global scales and/or at long time scales.

Biogenic volatile organic compounds (bVOCs) are global chemical signatures of life. bVOCs comprise chemically diverse gaseous compounds of biological origin and are emitted from and consumed in terrestrial ecosystems. We consider biological sources and sinks being mainly plants and soil life, especially the microbiota. bVOCs are receiving an increasing scientific interest since breakthroughs in analytics of compounds but also of plants and microbiota facilitate an integrative understanding.
bVOCs have various environmental functions. Some impact on the oxidative capacity of the troposphere, stratospheric ozone destruction, and contribute to aerosol formation. Others are involved in chemical signaling between plants, animals and microbes in terrestrial ecosystems and hence, connect organisms’ activities and behaviors beyond the canonical trophic foodweb theory. In the era of the anthropocene, land use and associated human forces alter bVOC flux dynamics by changing ecosystems and their properties.
Understanding bVOCs fluxes in and from terrestrial ecosystems has two conceptual dimensions. (a) They are ecological interaction signals and thus, are affecting ecological interactions and ecosystem functioning - which includes plant production in agriculture - and (b) they are relevant for atmospheric chemistry and thus land-atmosphere interactions. Both dimensions are inherently intertwined and can be seen as two sides of the same coin.
We would like to merge both dimensions in one single session at the EGU Biogeosciences Division to trigger discussions on future research perspectives - e.g. how to quantitatively determine and/or predict bVOC fluxes by considering interactions of biological actors. Also novel insights in the topic, and methodological developments and new approaches are highly welcomed.
Human activities are altering a range of environmental conditions, including atmospheric CO2 concentration, climate, and nutrient inputs. However, understanding and predicting their combined impacts on ecosystem structure and functioning and biogeochemical cycles is challenging. Divergent future projections of terrestrial ecosystem models reveal uncertainties about fundamental processes and missing observational constraints. Models are routinely tested and calibrated against data from ecosystem flux measurements, remote sensing, atmospheric inversions and ecosystem inventories. These model projections constrain the current mean state of the terrestrial biosphere, but they provide limited information on the sensitivity of ecophysiological, biogeochemical, and hydrological processes to environmental changes. Observational and ecosystem manipulation studies (e.g., Free-Air Carbon Dioxide Enrichment (FACE), nutrient addition or warming experiments) can complement modelling studies with unique insights and inform model development and evaluation.
This session focuses on how ecosystem processes respond to changes in CO2 concentration, warming, altered precipitation patterns, water and nutrient availability. It aims at fostering the interaction between the experimental and modelling communities by advancing the use of observational and experimental data for model evaluation and calibration. We encourage contributions from syntheses of multiple experiments, model intercomparisons and evaluations against ecosystem manipulation experiments, pre-experimental modelling, or the use of observations from "natural experiments". Contributions may span a range of scales and scopes, including plant ecophysiology, soil organic matter dynamics, soil microbial activity, nutrient cycling, plant-soil interactions, or ecosystem dynamics.

Gross photosynthetic CO2 uptake is the single largest component of the global carbon cycle and a crucial variable for monitoring and understanding global biogeochemical cycles and fundamental ecosystem services. Nowadays routine measurements of the net biosphere-atmosphere CO2 exchange are conducted at the ecosystem scale in a large variety of ecosystem types across the globe. Gross photosynthetic and ecosystem respiratory fluxes are then typically inferred from the net CO2 exchange and used for benchmarking of terrestrial biosphere models or as backbones for upscaling exercises. Uncertainty in the responses of photosynthesis and respiration to the climate and environmental conditions is a major source of uncertainty in predictions of ecosystem-atmosphere feedbacks under climate change. On the other hand, transpiration estimates both at ecosystem to global scales are highly uncertain with estimates ranging from 20 to 90 % of total evapotranspiration. The most important bottleneck to narrow down the uncertainty in transpiration estimates is the fact that direct measurements of transpiration are uncertain and techniques like eddy covariance measure only the total evapotranspiration.
During the last decade, technological developments in field spectroscopy, including remote and proximal sensing of sun-induced fluorescence, as well as in isotope flux measurements and quantum cascade lasers have enabled alternative approaches for constraining ecosystem-scale photosynthesis, respiration and transpiration. On the other hand, a variety of approaches have been developed to directly assess the gross fluxes of CO2 and transpiration by using both process based and empirical models, and machine learning techniques.
In this session, we aim at reviewing recent progress made with novel approaches of constraining ecosystem gross photosynthesis, respiration and transpiration and at discussing their weaknesses and future steps required to reduce the uncertainty of present-day estimates. To this end, we are seeking contributions that use emerging constrains to improve the ability to quantify respiration and photosynthesis processes, transpiration and water use efficiency, at scales from leaf to ecosystem and global. Particularly welcome are studies reporting advancements and new developments in CO2 and evapotranspiration flux partitioning from eddy covariance data, the use of carbonyl sulfide, stable isotopes approaches and sun-induced fluorescence.

Carbon allocation is a key process in ecosystems: it is coupled with plant growth, fuels metabolism and plays a crucial role for carbon sequestration in standing biomass and soil organic matter. While the importance of carbon allocation for plant and ecosystem functioning and the carbon balance is widely recognized, we still lack a comprehensive understanding of the underlying mechanisms, responses to global changes and wider biogeochemical implications. Open questions include: 1) what drives carbon allocation in plants and ecosystems?; 2) what is the fate of newly assimilated carbon?; 3) what determines the allocation of nonstructural carbon to growth, metabolism and storage?, 4) how does carbon allocation affect nutrient and water relations in plants and ecosystems?; and 5) how do allocation patterns change under changing environmental conditions and what are the consequences for biogeochemical cycles? This session invites contributions from observational, experimental and modelling studies.

Wide-spread permafrost thaw is expected to amplify the release of previously frozen material from terrestrial into aquatic systems: rivers, lakes, groundwater and oceans. Current projections include changes in precipitation patterns, active layer drainage and leaching, increased thermokarst lake formation, as well as increased coastal and river bank erosion that are further enhanced by rising water temperatures, river discharge and wave action. In addition, subsea permafrost that formed under terrestrial conditions but was later inundated might be rapidly thawing on Arctic Ocean shelves. These processes are expected to substantially alter the biogeochemical cycling of carbon but also of other elements in the permafrost area.
This session invites contributions on the mobilization of terrestrial matter to aquatic systems in the permafrost domain, as well as its transport, degradation and potential interaction with autochthonous, aquatic matter. We encourage submissions focusing on organic and inorganic carbon as well as on other elements such as nitrogen, phosphorus, silica, iron, mercury and others, from all parts of the global permafrost area including mountain, inland, coastal and subsea permafrost, on all spatial scales, in the contemporary system but also in the past and future, based on field, laboratory and modelling work.

Eco-evolutionary optimality (EEO) theory invokes the power of natural selection to eliminate uncompetitive trait combinations, and thereby shape predictable, general patterns in vegetation structure and composition. Although the implementation of process-based representations derived from EEO principles in vegetation and land-surface models is a relatively recent phenomenon, it is already yielding considerable improvements to our ability to simulate vegetation responses to changing climate and environmental conditions. For example, hypotheses derived from EEO principles are proving helpful in developing parsimonious representations of leaf-level processes such as photosynthesis and primary production, dark respiration, and stomatal behaviour. EEO approaches can also be applied to at whole plant and community levels, providing simple ways of representing plant interactions and ecosystem dynamics. Comparisons of EEO-based predictions against experimental data and field and remote-sensing observations provide a way of evaluating the robustness of the hypotheses, as well as discriminating between alternative EEO hypotheses.
This session is designed to bring together scientists applying EEO approaches to modelling plant behaviour from cellular to community scales, experimentalists and observationalists developing data sets that can be used to evaluate EEO hypotheses, and vegetation and land-surface modellers implementing EEO approaches in existing model frameworks. The session will explore the current state-of-the-art, as well as ways to move EEO-based approaches forward. The key objective is to bring together researchers from different communities working on EEO principles, promoting scientific exchanges that are much needed to develop robust, reliable and realistic next-generation Earth System Models.

A transition towards sustainable agriculture is needed to ensure that both present and future societies will be food secure. Current agricultural productivity is already challenged by several factors, such as climate change, availability and accessibility of water and other inputs, socio-economic conditions, and changing and increased demand for agricultural products. Agriculture is also expected to contribute to climate change mitigation, to minimize pollution of the environment, and to preserve biodiversity.
Assessing all these requires studying alternative land management at local to global scales and to assess agricultural production systems rather than individual products.
This session will focus on the modeling of any part of or entire agricultural systems under global change, addressing challenges in adaptation to and mitigation of climate change, sustainable intensification and environmental impacts of agricultural production. We welcome contributions on methods and data, assessments of climate impacts and adaptation options, environmental impacts, GHG mitigation and economic evaluations.

Global, collaborative research has the potential to address substantial knowledge gaps in peatland science. The integration of insights across individual study sites and disciplines, including those from biogeosciences, hydrology, and global environmental change, can help resolve key unknowns regarding the response of global peatlands to projected disturbances. We are more technologically capable than ever to conduct this much needed collaborative work, and today’s early career researchers will play a pivotal role in shaping the future of peatland science. The goal of this session is to bring together early career peatland researchers (within 7 years post PhD) across scientific fields to emphasize the commonalities and differences in our findings across geographical regions and peatland type. We encourage interdisciplinary submissions comparing processes and spatio-temporal scales in peatlands worldwide and/or studies with management implications, but also welcome localized and methodologically specific studies which have broader implications.

The majority of world forest ecosystems are subject to a number of natural disturbances (e.g. wildfires, pests, diseases, adverse weather events). These can severely affect their health and vitality by causing tree mortality or by reducing their ability to provide the full range of goods and services. Understanding and quantifying forest vulnerability to such disturbances and the underlying driving mechanisms is crucial to assess climate impacts and develop effective adaptation strategies.
This session will cover aspects ranging from observed and projected climate change to consequences for forest ecosystems and forest assessment, spanning a range of scales and conditions. In particular, we welcome submissions on the following subjects:
• Forest mortality and die-back phenomena under global warming.
• Evaluation of the effects of natural and anthropogenic disturbances on forest health and growth.
• Vulnerability of old-growth forests and mountainous forest ecosystems to climate change.
• Multidisciplinary approaches towards monitoring and modelling tree vulnerability at the local, regional and global scale.
• Estimation of resistance, resilience and recovery of forests in drought-prone areas.
• Interdisciplinary forestry research covering not only ecological but also economic and social aspects.
• Effects of forestry practices on forest health and vulnerability.
• Methods and tools for decision support and adaptation support in the forestry sector.
• Modelling growth at different scales: wood, tree, forest.

Land use and land cover change (LULCC), including land management, has the capacity to alter the climate by disrupting land-atmosphere fluxes of carbon, water and energy. Thus, there is a particular interest in understanding the role of LULCC as it relates to climate mitigation and adaptation strategies. Much attention has been devoted to the biogeochemical impacts of LULCC, yet there is an increasing awareness that the biogeophysical mechanisms (e.g. changes in surface properties such as albedo, roughness and evapotranspiration) should also be considered in climate change assessments of LULCC impacts on weather and climate. However, characterizing biogeophysical land-climate interactions remains challenging due to their complexity. If a cooling or a warming signal emerges depends on which of the biogeophysical processes dominates and on the size and pattern of the LULCC perturbation. Recent advances exploiting Earth system modelling and Earth observation tools are opening new possibilities to better describe LULCC and its effects at multiple temporal and spatial scales. This session invites studies that improve our general understanding of climate perturbations connected to LULCC from both biogeophysical and biogeochemical standpoints, and particularly those focusing on their intersection. This includes studies focusing on LULCC that can inform land-based climate mitigation and adaptation policies. Both observation-based and model-based analyses at local to global scales are welcome.

From pole to pole, peatlands contain up to 30% of the world’s soil carbon pool, illustrating their role in the global carbon cycle. Currently peatlands are under various pressures such as changing climate, land-use or nutrient loading with unknown consequences for their functioning as carbon sinks and stores and the uptake or release of the greenhouse gasses carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Simultaneously, increasing amount of restoration activities, aiming to return peatlands back to their original state are ongoing. It is, however, not clear how the carbon reservoir will react to these pressures and how resilient these ecosystems are. This session will focus on the observed or predicted changes on the biogeochemistry at peatlands, caused by climate change, nutrient loading or land-use. We invite studies concentrating, for example, on the effects of climate change on GHG flux or nutrient dynamics on pristine and managed peatlands, impact of drainage or restoration and subsequent vegetation succession on biogeochemistry, atmosphere-biosphere interaction, or studies on carbon stock changes demonstrating the impact of land-use or climate change. Experimental and modelling studies of both high- and low latitude peatlands are welcomed.
The health of plant natural communities, crop and forestry systems is constrained by increasing occurrence of natural and anthropogenic disturbances. Phenomena such as climate extremes, drought, flooding, insect outbreaks and wildfire are affecting the productivity of plant communities often leading to decline and mortality, forest dieback and alterations in distribution and productivity of the most important crops worldwide.
The mechanisms of plant decline, often related to hydraulic failure and reduction in photosynthesis, have not been fully unravelled and linked to specific measurable traits, leading to a need for multiple proxies.
Understanding how traits and their plasticity connect with the mechanisms determining plant health and species mortality is a key requisite for i) predicting plant population dynamics and climate change-driven changes in community composition in natural ecosystems and ii) forecasting possible changes in plant productivity in crop systems to manage cultivation factors to mitigate the climate change effects. This also applies to controlled environment agriculture systems for resource use optimization for sustainability goals, and to crop production in Space for exploration.
This session provides a forum on the role of functional traits (e.g., specific leaf area and anatomy, leaf nitrogen content, seed mass, plant/root architecture, phenology, quantitative wood anatomy, wood density, hydraulic traits, etc.) as indicators and proxies of plant status and post-disturbance resilience.
We encourage contributions to the session that: (i) provide quantitative knowledge regarding the intra- and inter-specific diversity in functional traits for predicting plant vulnerability to environmental stressors; (ii) assess the potential of traits to acclimate throughout an individual plant’s life under changing environmental conditions; (iii) show the ability of traits to serve as indicators of plant performance, survival and resilience; (iv) detect possible trade-offs among traits (e.g. coordination between hydraulic and photosynthetic processes) related to resource acquisition and allocation.
A multidisciplinary effort is needed to unravel plant acclimation and adaptation strategies and upscale gained information to evaluate implications for productivity of croplands, forests and natural ecosystems. Such information will be useful as input for dynamic global vegetation and crop models supporting international policy for sustainability.

A robust representation of the terrestrial carbon and water cycles requires fundamental understanding of biosphere-atmosphere interactions, particularly in a changing climate. Multiple processes determine how mass and energy exchanges scale from the leaf, to the whole plant, to the ecosystem, and eventually to the globe. Earth system models continue to evolve and incorporate increasingly complex processes across these scales, without however, reducing the uncertainties. Challenge remains to robustly formulate mechanistic underpinnings of biogeochemical processes across scales. The increasing amount of data at multiple scales, ranging from leaf-level measurements (e.g., gas exchange), tree-level measurements (e.g., sap flow and tree growth, dendroecology), ecosystem-level measurements (eddy covariance towers, UAVs, aircrafts) to Earth observation from space, are now opening new opportunities to tackle these challenges.
This session invites studies that improve our overall understanding of biosphere-atmosphere interactions by combining observations at different temporal and spatial scales as well as their seamless integration into modeling strategies. In addition to empirical multi-scale observations of carbon and water fluxes, we invite research that explore data-driven diagnostics and constraints for model evaluation (e.g., Emergent Constraints), data-driven parameterizations in mechanistic models (e.g., ESMs) and other developments of data-driven/hybrid modelling strategies (i.e., seamless fusion of data-driven approaches and mechanistic models) for an integrated understanding of carbon and water fluxes across scales.

Exchange of greenhouse gases (GHGs) such as methane (CH4) and nitrous oxide (N2O) in forest ecosystems has traditionally focused on gas flux measurements from soil or between biosphere and atmosphere in the surface layer only. However, it has become evident that trees may play an important role in the net exchange of these GHGs in forests. Trees can contribute to ecosystem exchange by uptake and transport of soil-produced CH4 and N2O to the atmosphere, in-situ production and consumption of both gases in plant tissues, and alternation of carbon- and nitrogen-turn-over in adjacent soil. However, the contribution of these individual processes to the net ecosystem GHGs exchange is still unclear and seems to depend on many aspects as tree species, forest ecosystem type, environmental parameters and seasonal dynamics. Interactions between soil, vegetation and the atmosphere exert a crucial role controlling the global budget of these gases.
This session seeks to bring together scientists working on the exchange of CH4 and N2O in forest ecosystems at any relevant scale, and from the full climatic and hydrological forest range. We therefore welcome contributions on (i) production and consumption processes in soils and plant tissues; (ii) gas transport processes in soil-tree-atmosphere continuum; (iii) gas flux measurements on the forest floor, cryptogams, tree stems or at leaf and canopy level; (iv) micrometeorological measurements using flux towers, satellite, or modelling approaches that seek to integrate our understanding of CH4 and N2O exchange in forest ecosystems.

Dear colleagues and friends,
We are going to have a session dinner together on Wednesday, May 25 2022, from 8 p.m.
at the Brandauers Bierbögen (https://www.bierig.at/bierbogen/; The tables are reserved on Martin Maier).
The session dinner will be together with our colleagues from the session
SSS8.3 "Soil gases : production, consumption and transport processes".
We are looking forward to meeting you all in Vienna or online next week.
The tropics play a critical role in regulating the global climate system through the exchange of greenhouse gases (GHG), water, and energy between soil, vegetation and the atmosphere. Tropical forests, wetlands, and grasslands store sizeable amounts of carbon, and provide other important ecosystem services such as wood, foods, and biodiversity. Historic and recent human activities have, however, resulted in intensive transformation of these ecosystems impacting the cycling of nutrients, carbon, water, and energy. Increasing tropical forest degradation and loss, peatland drainage, grassland conversion, and agriculture expansion to meet demands for timber and food releases stored carbon and drives growing GHG emissions in the tropics, an issue of increasing international concern. Preventing land-use change and restoring degraded tropical ecosystems offers the possibility to mitigate anthropogenic GHG emissions, but estimates of the potential GHG benefits of such activities are overall poorly constrained.
Here we invite contributions that provide insights on how land-use, land-use change, and ecosystem conservation and restoration influence ecohydrology, biogeochemical cycles, and GHG emissions (CO2, CH4, N2O) in tropical ecosystems at plot, landscape, and continental scale. Examples include nitrogen and carbon cycle in the soil and vegetation, the exchange of GHG between soil and atmosphere as well as vegetation and atmosphere, changes in the energy balance, impacts on the water cycle, scaling issues from plots to country to continent as well as the influence of management activities (e.g. fertilization, drainage, etc. ) on GHG fluxes. The aim of this session is to provide a synthesis of knowledge on exchanges of water and energy as well as biogeochemical processes influencing carbon storage and GHG emissions from tropical ecosystems that are degraded, converted, or restored. Experimental studies (e.g., chamber or eddy covariance flux measurements, laboratory based, etc.), inventories, as well as remote sensing or modelling studies are welcome, and we encourage contributions that compare GHG emissions in pristine and disturbed ecosystems.
Managed agricultural ecosystems (grassland and cropland) are an important source and/or sink for various gases in the atmosphere including greenhouse gases (GHG) and reactive trace gases like ammonia. Due to the simultaneous influence of various environmental drivers and management activities (e.g. fertilizer application, harvest, grazing) the flux patterns are often complex and difficult to attribute to individual drivers.
While process-based models are designed to combine all relevant effects on gas emissions, some processes like denitrification (as a source of N2 and N2O) have rarely been validated due to the lack of suitable data-sets, and thus results of their application on site and regional scales are still highly uncertain.
The session addresses experimentalists and modelers working on carbon and nitrogen cycling processes and related gas fluxes on plot, field, landscape, and regional scale.
We invite contributions from the following fields: methodical advances in measuring and modelling of soil processes; measurements of gas fluxes under field or field-like conditions with a focus on controlling factors; method comparisons including micrometeorological and chamber techniques as well as tracer and isotope (or isotopologue) approaches or other novel methods; process-based modelling at various scales; and the linking of soil processes and emissions to microbial community parameters.
Climate change has already started to affect dynamic feedbacks between plant, soil, and microbial communities and thus strongly influences terrestrial biogeochemical cycling. In this session we address the questions: What is the impact of changing environmental conditions on the plant-soil system, and the resulting effects on soil biogeochemistry? And how do we represent soils in (global) models and upscale experimental data using process-based understanding of the controls on biogeochemical cycles? In this session we seek contributions addressing how biogeochemical cycles in soils vary across gradients in climate, vegetation, and soil properties, and how they may respond to future changes.
We invite contributions from manipulative field experiments, observations in natural-climate gradients, and modelling studies that explore climate change impacts on plant-soil interactions, biogeochemical cycling of C, N, P, microbial diversity and decomposition processes, and deep -soil biogeochemistry. Researchers are encouraged to present their empirical and/or modeling studies addressing soil dynamics along geochemical and climatic gradients. Submissions that adopt novel approaches, e.g. molecular, isotopic, or synthesize outputs from large-scale, field experiments focusing on plant-soil-microbe feedbacks to warming, wetting, drying and thawing are very welcome.

The need to predict ecosystem responses to anthropogenic change, including but not limited to changes in climate and increased atmospheric CO2 concentrations, is more pressing than ever. Global change is inherently multi-factorial and as the terrestrial biosphere moves into states without a present climate analogue, mechanistic understanding of ecosystem processes and their linkages with vegetation diversity and ecosystem function is vital to enable predictive capacity in our forecast tools.
This session aims to bring together scientists interested in advancing our fundamental understanding of vegetation and whole-ecosystem processes. We are interested in contributions focused on advancing process- and hypothesis-driven understanding of plant ecophysiology, biodiversity and ecosystem function. We welcome studies on a range of scales from greenhouse and mesocosm experiments to large field manipulative experiments, remote sensing studies and process-based modelling. We encourage contributions of novel ideas and hypotheses in particular those from early stage researchers and hope the session can create an environment where such ideas can be discussed freely.

With the multitude of functions and services simultaneously and increasingly required from forests, it is crucial to improve our understanding of these complex ecosystems, also in light of the potential alterations introduced by different global change drivers, mostly due to anthropogenic activities.
Natural disturbances are a primary driver of forest dynamics, shaping their composition and structure, and determining succession trajectories. Humans have always interacted with natural disturbances, and are in turn affected by the hazards posed by these events. Forest management still requires solid scientific input on how to increase the resistance and resilience of forests, and manage naturally disturbed landscapes to promote forest regeneration.
In this session, we invite contributions from all fields in order to promote knowledge on forest ecology and management, aiming at developing methodologies and strategies to mitigate the impact of global change and its consequences on natural disturbances affecting forest ecosystems worldwide. This session addresses in particular the potentials and limitations of various remote sensing applications in forestry, with a focus on the identification and integration of different methodologies and techniques from different sensors and in-situ data for providing qualitative and quantities forest information.
A key development in remote sensing has been the increased availability of data with very high temporal, spatial and spectral resolution. In the last decades, several types of remote sensing data, including optical, multispectral, radar, LiDAR from terrestrial, UAV, aerial and satellite platforms, have been used to detect, classify, evaluate and measure the earth surface, including different vegetation cover and forest structure. For the forest sector, such information allows efficient quantification of the state and monitoring of changes over time and space, in support of sustainable forest management, forest and carbon inventory or for monitoring forest health and their disturbances.
However, to meet the various information requirements, different data sources should be adopted according to the application, the level of detail required and the extension of the area under study. The integration of in-situ measurements with satellite/airborne/UAV imagery, Structure from Motion, LiDAR and geo-information systems offers new possibilities, especially for interpretation, mapping and measuring of forest parameters and will be a challenge for future research and application.

Peatland restoration for conservation purposes can solve many problems related to drained peatlands and has been implemented for decades now. However, innovative management measures that sustain economically viable biomass production while reducing negative environmental impacts including greenhouse gas (GHG) emissions, fire risk and supporting ecosystem services of organic soils are only currently studied. Those management measures include, but are not limited to, productive use of wet peatlands (paludiculture ), improved water management in conventional agriculture and innovative approaches in conservation-focused rewetting projects. We invite studies addressing all types of peatland management, i.e. agriculture, forestry and “classical” restoration, their integration into GHG inventories and their impacts on ecosystem services and biodiversity regionally and nationally as well as their integration into GHG inventories. Work on all spatial scales from laboratory to national level addressing biogeochemical and biological aspects and experimental and modelling studies are welcome. Furthermore, we invite contributions addressing policy coherence and identifying policy instruments for initiating and implementing new management practices on organic soils. Implementation and efficiency of management practices depends not only on hydrogeology and climate but also on other regional factors. Therefore, we hope to host contributions from different geographical regions where peatlands are important including boreal, temperate and tropical peatlands.

The ecological stability, soil degradation, and hydrological extremes are the main driving elements and powerful tools associated with climate change on reducing or increasing the acceleration of climate change.
Climate change is a natural process, but the latest scientific research proves that it is significantly accelerated by human activity. Adequate steps can be taken by humans (for instance land use/land cover changes) in order to reduce the risks and consequences of the effects of climate change. Despite this knowledge, which is well known, progress is still slow, and the negative consequences prevail over the positive remedies.
The session should reflect, discuss, and share scientific knowledge on a local and regional scale with the aim to increase innovative knowledge thanks to multidisciplinary links at national, international, and global levels.
This session is open within a wide range of relevant scientific topics as follows:
• hydrological extremes as one of the main impacts of climate change;
• lack of precipitation or extreme precipitation - how to reduce and decrease these extremes by adequate measures;
• the connection between deteriorating ecological stability and climate change;
• new methods and procedures for reducing existing manifestations of climate change (such as soil degradation, carbon sequestration, changes in natural, agricultural, and forest ecosystems, reduction of overall ecological stability and character of the landscape);
• proposal of measures to prevent the occurrence of the above-mentioned impacts;
• the sustainability of management practices, the importance of appropriate land use management as the main tool for preventing degradation processes, floods, and droughts, improving the condition of forest ecosystems in order to increase the overall character of the landscape.

It is wildly accepted that the functions of soil are intimately linked to its structure and state of aggregation. Water retention characteristics, ventilation, fluids-flow, and transport of mobile material - from the solutes and colloids to suspended particles - depends intricately on the properties of the void network structure and the composition and properties of the solid-fluid interfaces therein. Extent and rates of organic matter storage, nutrient supply, contaminant retardation, but also microbial colonization, root penetration and hyphae exploration patterns are part of a complicated feedback loop that not only creates structure but results in its change in space and time. Processes and mechanisms that result in structure formation and dynamics in soil are intensively studied and vividly debated: In particular the role of aggregates and aggregation is discussed intensively. With the advent of sophisticated spectroscopic, microscopic, and tomographic techniques that enable to study structure, composition and interface properties at the submicron scale even down to the atomic scale, testing hypothesis on the co-evolution of structure, properties and emerging function on soils from the atom to the pedon scale is rapidly progressing. In particular if techniques exploring void-interface structure and properties are combined with field observational data and experimental pedogenesis in a joint fashion, testing of hypothesis can much better be directed towards generalizable theories on the mechanistic linkage of structure and function in soils and their evolution during pedogenesis. With this symposium we aim to discuss and debate the recent achievements, current obstacles, and future research directions to contribute to a synoptic understanding of the relationship between soil architecture and functions across scales. We specifically invite contribution from the different fields of soil research employing one or, in a joint fashion, more than one approach of the variety of experimental, observational, instrumental and computational methods.

Soil organic matter (SOM) plays a vital role not only in soil fertility and quality (by providing a number of physical, chemical, and biological benefits), but also in carbon cycling. SOM contains a vast range of diverse organic structures, and also a living component (microorganisms) with various residence times that define the central role SOM plays in the soil. The decline of SOM represents one of the most serious threats facing many arable lands of the world. One of the efficient approaches to increase SOM content and decrease land degradation is the application of organic amendments, such as crop residues and animal manures. Nowadays, organic amendments originate from many kinds of organic wastes, which are being increasingly produced mainly by farms, agro-food industries, municipalities, and energy plants. Besides serving as a source of organic matter and plant nutrients, these materials may contribute to reduce soil contamination, erosion, and desertification, as well as mitigate climate change. At the same time, a safe and useful application of organic amendments requires an in-depth scientific knowledge of their nature and impacts on the SOM pools and factions, soil-plant system, as well as on the surrounding environment.
This session will combine the current research and recent advances on the use of organic amendments in modern agriculture as well as for the restoration of degraded soils. Field and laboratory studies focused on the effects of management practices, climate change, environmental conditions, soil properties are highly welcome.

Soil organic matter (SOM) is well known to exert a great influence on physical, chemical, and biological soil properties, thus playing a very important role in agronomic production and environmental quality. Globally SOM represents the largest terrestrial organic C stock, which can have significant impacts on atmospheric CO2 concentrations and thus on climate. The changes in soil organic C content are the result of the balance of inputs and losses, which strongly depends on the processes of organic C stabilization and protection from decomposition in the soil. This session will provide a forum for discussion of recent studies on the transformation, stabilization and sequestration mechanisms of organic C in soils, covering any physical, chemical, and biological aspects related to the selective preservation and formation of recalcitrant organic compounds, occlusion by macro and microaggregation, and chemical interaction with soil mineral particles and metal ions.

Soil structure and its stability determine soil physical functions and chemical properties such as water retention, hydraulic conductivity, susceptibility to erosion, and redox potentials. These soil physical and chemical characteristics are fundamental for biological processes, among them root penetration and organic matter and nutrient dynamics. The soil pore network forms the habitat for soil biota, which in turn actively reshape it according to their needs. The soil biota, root growth, land management practices like tillage and abiotic drivers (e.g. wetting/drying cycles) lead to a constant evolution of the arrangement of pores, minerals and organic matter. With this, also the soil functions and properties are perpetually changing. The importance of the interaction between soil structure (and thus soil functions) on one side and soil biology, climate and soil management on the other, is highlighted by recent research outcomes, which are based on advanced imaging techniques, novel experimental setups and modelling approaches. Still, present studies have barely scratched the surface of what there is to discover.
In this session, we are inviting contributions on the formation and alteration of soil structure and its associated soil functions over time. Special focuses are on feedbacks between soil structure dynamics and soil biology as well as the impact of mechanical stress exerted by heavy vehicles deployed under land management operations. Further, we encourage submissions that are exploring new modelling concepts, integrating complementary measurement techniques or aim at bridging different scales.

The soil is a key system of the biosphere that supports the existence and development of human civilization. However, the growing anthropic activities are accompanied by an expansion of soil pollution. From a geochemical point of view, anthropic activities lead to the emergence of a new state of the biosphere - the noosphere, when anthropogenic chemical elements and their compounds are added to natural soil. This determines the current spatial heterogeneity of the chemical composition of the soil and vegetation cover. Such an alteration to soil composition/properties can cause negative biological impacts on both native and introduced species in local biocenosis, as well as the emergence of endemic diseases among plants animals, and humans. Human diseases can be aggravated by the fact that Homo sapiens evolving as a species under certain environmental/geochemical conditions inherited a corresponding need for certain dietary elements to maintain homeostatic regulation. As a result, people, like other organisms, need to ingest elements in the correct amounts, otherwise, they suffer from a deficiency or excess of these elements. A negative reaction may occur when the species’ natural metabolism fails to compensate for this imbalance in the life cycle. Therefore, complex studies on the identification, spatial distribution, migration, and concentration of the contaminants in soils, plants, and surface and groundwater in urban, mining, agricultural/forest, and natural areas, as well as its biological effects, is an essential issue and important task for 1)identification of zones of different natural and man-made ecological risks; 2)understanding contaminants’ pathways and impact, and 3)mitigation or elimination of negative biological effects, including the spread of non-communicable endemic diseases.
At this session, participants are invited to present their new data on soil pollution, as well as to show ideas and approaches to the solution of the problem of soil reclamation, to show results that contribute to modern knowledge on the ecological and geochemical assessment of various regions of the world exposed to anthropic geochemical impact, including industrial pollution, transport, mining and use of fertilizers and biocides. We also welcome presentations devoted to methodological problems on soil pollution assessment, the creation of ecological and geochemical databases, and compiling risk maps. We hope that live discussion will contribute to each study.

Soil pollution is a global threat which seriously affects biodiversity in (agro)ecosystems and compromises the quality of the food and water. Besides naturally elevated levels of potentially toxic elements and compounds (elevated mineralization of soils, accumulation of phenolics), most contaminants originate from human activities such as industrial processes and mining, poor waste management, unsustainable farming practices and accidents.One of the most important issues in pollution research is the assessment and evaluation of pollution including assessment and evaluation of the distribution of pollutants, mobility, chemical speciation as well as evaluation of the probability of soil-plant transfer and accumulation in plants.
This session aims to bring together contributions of all aspects of biogeochemical research related to soil pollution risk assessment including (but not limited to) assessment of pollution status, geochemical mapping, analysis of element cycling within soils and ecosystems as well as ecotoxicological considerations.
We welcome presentations of laboratory and field research results as well as theoretical studies. We intend to bring together scientists from multiple disciplines. Young researchers are especially encouraged to submit their contributions.
Soils sustain complex patterns of life and act as biogeochemical reactors producing and consuming a large amount of gas molecules. They play a fundamental role in the temporal evolution of the atmospheric gases concentration (greenhouse gases, biogenic volatile organic compounds, nitrous acid, isotopic composition…) and they modulate the soil pore gas concentrations affecting many soil functions, such as root and plant growth, microbial activity, and stabilization of soil organic carbon. Gases production, consumption and transport in the different soil types have then some important ecological implications for the earth system.
The factors affecting the soil gas processes range from physical soil structure (porosity, granulometry,…), type and amount of living material (microbiota, root systems), soil chemistry properties (carbon and nitrogen contents, pH,…) and soil meteorological conditions (temperature, water content,…). A large mixing of different scientific backgrounds are therefore required to improve the knowledge about their influence which is made even more difficult due to the very large spatial heterogeneity of these factors and the complexity of their interactions.
This session will be the place to present and exchange about the measurement techniques, data analyses and modelling approaches that can help to figure out the temporal and spatial variability of the production/consumption and transport of gases in soils. In addition to mechanisms related to carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), including the geochemical ones, the abstracts about volatile carbon compounds produced by plant and microbial or Helium and Radon geogenic emissions production are welcome
A special attention will be given to the researches including special water situations as edaphic drought or waterlogged soils

Soil is the largest carbon (C) reservoir in terrestrial ecosystems with twice the amount of atmospheric C and three times the amount in terrestrial vegetation. Carbon related ecosystem services include retention of water and nutrients, promoting soil fertility and productivity and soil resistance to erosion. In addition, changes in the soil C can have strong implications for greenhouse gas emissions from soil with implications in environmental health.
Drivers controlling C pools and its dynamics are multiple (e.g. land use/vegetation cover, climate, texture and bedrock, topography, soil microbial community, soil erosion rates, soil and other environment management practices, etc. ) and mutually interacting at various time and spatial scales. At the one time, rate of soil C loss can be high due to both climatic constrains or unsuitable management. Thus, investigating C dynamics include the adaptation of the management factors to the actual climate, the climate change and climatic extreme events to provide a better understanding of carbon stabilization processes and thus support decision making in soil management and climate adaptation strategies.
The present session highlights the importance of soil C changes, and the interaction among the mechanisms affecting C concentration and stocks in soil, including soil management. Discussion about proxies of measurement and modelling organic and inorganic C flows, concentration and stocks, with special emphasis to cropping systems and natural/semi-natural areas, is encouraged. These proxies should be approached at varying the availability of soil and environment information, including, e.g., soil texture, rainfall, temperature, bulk density, land use and land management, or proximal and remote sensing properties. Studies presented in this session can aim to a wealth of aims, including soil fertility, provision of ecosystem services, and their changes, and the implication for economy, policy, and decision making.
Types of contribution appreciated include, but are not limited to, definitive and intermediate results; project outcomes; proposal of methods or sampling and modelling strategies, and the assessment of their effectiveness; projection of previous results at the light of climate change and climatic extremes; literature surveys, reviews, and meta-analysis. These works will be evaluated at the light of the organisation of a special issue in an impacted journal
Viticulture is one of the most important agricultural sectors of Europe with an average annual production of 168 million hectoliters (54% of global consumption). The concept of “Terroir” links the quality and typicity of wine to the territory, and, in particular, to specific environmental characteristics that affect the plant response (e.g. climate, geology, pedology). The environmental factors that drive the terroir effect vary in space and time, as well as soil and crop management.
Understanding the spatial variability of some environmental factors (e.g. soil) is very important to manage and preserve terroirs and face the current and future issue of climate change. In this sense, it is important to stress that in the last decade, the study of terroir has shifted from a largely descriptive regional science to a more applied, technical research field, including: sensors for mapping and monitoring environmental variables, remote sensing and drones for crop monitoring, forecast models, use of microelements and isotopes for wine traceability, metagenome approach to study the biogeochemical cycles of nutrients.
Moreover, public awareness for ecosystem functioning has led to more quantitative approaches in evidencing the relations between management and the ecosystem services of vineyard agroecosystems. Agroecology approaches in vineyard, like the use of cover crops, straw mulching, and organic amendments, are developing to improve biodiversity, organic matter, soil water and nutrient retention, preservation from soil erosion.
On those bases, the session will address the several aspects of viticultural terroirs:
1) quantifying and spatial modelling of terroir components that influence plant growth, fruit composition and quality, mostly examining climate-soil-water relationships; 2) terroir concept resilience to climate change; 3) wine traceability and zoning based on microelements and isotopes; 4) interaction between vineyard management practices and effects on soil and water quality as well as biodiversity and related ecosystem services.
About 800 Pg soil carbon has been frozen for centuries to millennia. A large fraction of it is assumed to be thawed due to climate change in the near future. A rapid mineralization of this carbon to carbon dioxide or methane will directly alter the global carbon cycle resulting in positive feedback mechanisms that even accelerate climate change. However, permafrost-affected soils and the organic matter stored within are distributed heterogeneously with depth and across ecosystems. Is such thawing organic matter accessible to microorganisms and vulnerable to microbial decay, and hence will it be decomposed fast? Will a large part of it be stabilized at mineral surfaces or in soil aggregates, or will stabilization processes known from temperate soils be rather ineffective? Furthermore, what is the effect of hydrological changes to carbon mineralization or stabilization, particularly with respect to energy constraints of microorganisms? What will be effects of changing vegetation functions to soil organic matter dynamics? This session invites papers that investigate decomposition versus stabilization of thawing permafrost or active layer-organic matter. Contributions may be based on laboratory experiments, field observations, or modelling from the process level to the global scale.

Peatlands develop in specific hydrological settings and are thus sensitive to changes in climate and hydrological boundary conditions. The hydrology of peatlands is fundamental to their functions and development. Soil hydrological properties can change drastically after disturbances such as drainage, permafrost thaw, or mechanical compaction, causing challenges for both model parameterization and re-wetting measures. Pristine peatlands offer and regulate many ecosystem services such as biodiversity, carbon storage, and nutrient retention. Hydrology is a key control for a number of these services. Furthermore, the effects of peatlands (both pristine and disturbed) on flood retention, support of low flows and regional climate are much debated. As hydrological and biotic processes in peatlands are strongly coupled, estimating the eco-hydrological response of peatlands under climate change and linking it to vegetation development and greenhouse gas emissions is a demanding task for modelers. This session addresses peatlands in all latitudes, including especially permafrost and tropical peatlands for which field studies are scarce and the inclusion into Earth system models is largely pending.
This session focuses on:
(1) hydrological processes operating in all types of peatlands (pristine, disturbed, degraded, drained, managed, rehabilitated or re-wetted) in northern and tropical latitudes, and
(2) the first-order control of peatland hydrology on all kinds of peatland functions.
We aim to boost knowledge transfer across spatial/temporal scales and methods; from the pore to the global scale, including laboratory, field, remote sensing, and modeling studies on hydrological, hydrochemical, biogeochemical, ecohydrological or geophysical topics, as well as ecosystem service assessments.

Evapotranspiration (ET) is the key water flux at the interface of soil, vegetation and atmosphere. Methods to quantify this flux (and its individual components) have been developed within different research disciplines encompassing plant physiology, soil science, meteorology, hydrology and more. However, each method refers to a specific measurement scale and contains its own uncertainties. Bridging these scales for comparisons between the different methods – as well as remote sensing products and model outputs – requires careful consideration of the associated uncertainties and scaling assumptions.
This session will mainly focus on the variety of ET estimates from different in-situ devices such as lysimeters, sap flow sensors, eddy covariance stations, scintillometers, approaches like the Bowen ratio method and others, including reporting and comparing the respective uncertainties of the methods. Additionally, we want to address the scale dependency of the various approaches and the scale gap between in-situ ET data, remote sensing products and catchment- or landscape-scale modelled ET. We welcome contributions that (1) assess and compare established and new in-situ ET measurements, (2) address uncertainty in the respective methods, (3) analyse trends as well as spatial and temporal patterns (including day- and nighttime processes) in in-situ measured ET data, (4) include cross-scale comparisons and scaling approaches and (5) incorporate in-situ measurements into modeling approaches.
Tree rings are one of nature’s most versatile archives, providing insight into past environmental conditions at annual and intra-annual resolution and from local to global scales. Besides being valued proxies for historical climate, tree rings are also important indicators of plant physiological responses to changing environments and of long-term ecological processes. In this broad context we welcome contributions using one or more of the following approaches to either study the impact of environmental change on the growth and physiology of trees and forest ecosystems, or to assess and reconstruct past environmental change: (i) dendrochronological methods including studies based on tree-ring width, MXD or Blue Intensity, (ii) stable isotopes in tree rings and related plant compounds, (iii) dendrochemistry, (iv) quantitative wood anatomy, (v) ecophysiological data analyses, and (vi) mechanistic modelling, all across temporal and spatial scales.

Biological and ecological experimental studies in laboratory and nature, and their applications to the paleo- and future understanding of marine environments
In order to discuss Earth marine realms and answer questions about biotic evolution and ecosystem functioning in the Past, Present and Future, scientists try to take various laboratory- or natural-based experimental approaches. This includes experiments controlling environmental variables, experiments with stable or radioactive isotopic biomarkers, breeding experiments, genetic analyses (e.g. ancient DNA), or so-called natural laboratories (e.g. the Lessepsian invasion, natural CO2 vents functioning as ocean acidification analogues, tsunami landslides and turbidites, and many other natural situations strongly influencing the environment). Altogether, they unriddle faunal and ecosystem functional responses to changing connectivity patterns, habitat change or global change threats. These experimental approaches are effective to make clear how biotic evolution takes place in nature, how ecosystems also act as functional labs and how Earth systems have moved and can move dynamically. They enable us to make more robust projections into the future or decipher past ecosystem trajectories with potential analogues to future change. In this session we welcome contributions that use experimental approaches in this context, but also discussing biogeochemical proxies that fix information of past environmental change during biomineralization in calcareous or siliceous tests.

The coastal ocean has been increasingly recognized as a dynamic component of the global carbon budget. This session aims at fostering our understanding of the roles of coastal environments and of exchange processes, both natural or perturbed, along the terrestrial / coastal sea / open ocean continuum in global biogeochemical cycles. During the session recent advancements in the field of coastal and shelf biogeochemistry will be discussed. Contributions focusing on carbon and nutrient and all other element's cycles in coastal, shelf and shelf break environments, both pelagic and sedimentary, are invited.
This session is multidisciplinary and is open to observational, modelling and theoretical studies in order to promote the dialogue. The session will comprise subsections on coastal carbon storage, and on benthic biogeochemical processes.

Our ability to understand biogeochemical cycles of carbon, nitrogen and phosphorus in aquatic ecosystems has evolved enormously thanks to advancements in in situ and laboratory measurement techniques. We are now able to provide a detailed characterisation of aquatic organic matter with spectroscopic and chromatographic methods and collect data on nitrogen and phosphorus concentrations in relation to highly dynamic hydrological events thanks to automated in situ instruments. Therefore, the aim of this session is to demonstrate how this methodological advancement improves our understanding of coupled hydrological, biogeochemical and ecological processes in aquatic environments controlling the fate of organic matter, nutrients and other chemicals.
Specifically, our ability to characterise different fractions of natural organic matter and organic carbon has increased thanks to a range of analytical methods e.g. fluorescence and absorbance spectroscopy, mass spectrometry and chromatography combined with advanced data mining tools. Matching the water quality measurement interval with the timescales of hydrological responses (from minutes to hours) thanks to automated in situ wet-chemistry analysers, optical sensors and lab-on-a-chip instruments has led to discovery of new hydrochemical and biogeochemical patterns in aquatic environments e.g. concentration-discharge hysteresis and diurnal cycles. We need to understand further how hydrochemical and ecological processes control those patterns, how different biogeochemical cycles are linked in aquatic environments and how human activities disturb those biogeochemical cycles by emitting excess amounts of nutrients to aquatic systems. In particular, there is a growing need to better characterise the origins, delivery pathways, transformations and environmental fate of organic matter and nutrients in aquatic environments along with identification of robust numerical tools for advanced data processing and modelling.

The Indian Ocean is unique among the other tropical ocean basins due to the seasonal reversal of monsoon winds and concurrent ocean currents, lack of steady easterlies that result in a relatively deep thermocline along the equator, low-latitude connection to the neighboring Pacific and a lack of northward heat export due to the Asian continent. These characteristics shape the Indian Ocean’s air-sea interactions, variability, as well as its impacts and predictability in tropical and extratropical regions on (intra)seasonal, interannual, and decadal timescales. They also make the basin particularly vulnerable to anthropogenic climate change, as well as related extreme weather and climate events, and their impacts for surrounding regions, which are home to a third of the global population. Advances have recently been made in our understanding of the Indian Ocean’s circulation, interactions with adjacent ocean basins, and its role in regional and global climate. Nonetheless, significant gaps remain in understanding, observing, modeling, and predicting Indian Ocean variability and change across a range of timescales.
This session invites contributions based on observations, modelling, theory, and palaeo proxy reconstructions in the Indian Ocean that focus on recent observed and projected changes in Indian Ocean physical and biogeochemical properties and their impacts on ecological processes, diversity in Indian Ocean modes of variability (e.g., Indian Ocean Dipole, Indian Ocean Basin Mode, Madden-Julian Oscillation) and their impact on predictions, interactions and exchanges between the Indian Ocean and other ocean basins, as well as links between Indian Ocean variability and monsoon systems across a range of timescales. In particular, we encourage submissions on weather and climate extremes in the Indian Ocean, including marine heatwaves and their ecological impacts. We also welcome contributions that address research on the Indian Ocean grand challenges highlighted in the recent IndOOS Decadal Review, and as formulated by the Climate and Ocean: Variability, Predictability, and Change (CLIVAR), the Sustained Indian Ocean Biogeochemistry and Ecosystem Research (SIBER), the International Indian Ocean Expedition 2 (IIOE-2), findings informed by the Coupled Model Intercomparison Project version 6 (CMIP6) on past, present and future variability and change in the Indian Ocean climate system, and contributions making use of novel methodologies such as machine learning.

The interaction between the ocean and the cryosphere in the Southern Ocean has become a major focus in climate research. Antarctic climate change has captured public attention, which has spawned a number of research questions, such as: Is Antarctic sea ice becoming more vulnerable in a changing climate? Where and when will melting of ice shelves by warm ocean waters yield a tipping point in Antarctic climate? What role do ice-related processes play in nutrient upwelling on the continental shelf and in triggering carbon export to deep waters? Recent advances in observational technology, data coverage, and modeling provide scientists with a better understanding of the mechanisms involving ice-ocean interactions in the far South. Processes on the Antarctic continental shelf have been identified as missing links between the cryosphere, the global atmosphere and the deep open ocean that need to be captured in large-scale and global model simulations.
This session calls for studies on physical and biogeochemical interactions between ice shelves, sea ice and the ocean. The ice-covered Southern Ocean and its role in the greater Antarctic climate system are of major interest. This includes work on all scales, from local to basin-scale to circumpolar. Studies based on in-situ observations and remote sensing as well as regional to global models are welcome. We particularly invite cross-disciplinary topics involving physical and biological oceanography, glaciology or biogeochemistry.

The ocean surface mixed layer mediates the transfer of heat, freshwater, momentum and trace gases between atmosphere, sea ice and ocean, thus playing a central role in the dynamics of our climate. This session will focus on the surface mixed layer globally, from the coastal ocean to the deep ocean. We will review recent progress in understanding the key dynamical and biogeochemical processes taking place in the mixed layer: surface waves, Langmuir circulations and turbulence, shear-induced mixing, internal waves, coherent structures, fronts, frontal instabilities, entrainment and detrainment at the mixed layer base, convection, restratification, dynamics of the euphotic layer, carbon and nutrient cycling, etc. The improvement of the representation of surface mixed layer processes in numerical models is a complex and pressing issue: this session will bring together new advances in the representation of mixed layer processes in high resolution numerical models, as well as evaluation of mixed layer properties in climate models using most recent observational datasets. The coupling of the ocean and atmospheric boundary layers as well as the special processes occurring under sea ice and in the marginal sea ice zone will be given special consideration. This session welcomes all contributions related to the study of the oceanic mixed layer independent of the time- and space scales considered. This includes small scale process studies, short-term forecasting of the mixed layer characteristics for operational needs, studies on the variability of the mixed layer from sub-seasonal to multi annual time scales and mixed layer response to external forcing. The use of multiple approaches (coupled numerical modeling, reanalyses, observations) is encouraged.

The rapid decline of the Arctic sea ice in the last decade is a dramatic indicator of climate change. The Arctic sea ice cover is now thinner, weaker and drifts faster. Freak heatwaves are common. On land, the permafrost is dramatically thawing, glaciers are disappearing, and forest fires are raging. The ocean is also changing: the volume of freshwater stored in the Arctic has increased as have the inputs of coastal runoff from Siberia and Greenland and the exchanges with the Atlantic and Pacific Oceans. As the global surface temperature rises, the Arctic Ocean is speculated to become seasonally ice-free by the mid 21st century, which prompts us to revisit our perceptions of the Arctic system as a whole. What could the Arctic Ocean look like in the future? How are the present changes in the Arctic going to affect and be affected by the lower latitudes? What aspects of the changing Arctic should observational, remote sensing and modelling programmes address in priority?
In this session, we invite contributions from a variety of studies on the recent past, present and future Arctic. We encourage submissions examining interactions between the ocean, atmosphere and sea ice, on emerging mechanisms and feedbacks in the Arctic and on how the Arctic influences the global ocean. Submissions taking a cross-disciplinary, system approach and focussing on emerging cryospheric, oceanic and biogeochemical processes and their links with land are particularly welcome.
The session supports the actions of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030) towards addressing challenges for sustainable development in the Arctic and its diverse regions. We aim to promote discussions on the future plans for Arctic Ocean modelling and measurement strategies, and encourages submissions on the results from IPCC CMIP and the recent observational programs, such as the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC). This session is cosponsored by the CLIVAR /CliC Northern Ocean Regional Panel (NORP) that aims to facilitate progress and identify scientific opportunities in (sub)Arctic ocean-sea-ice-atmosphere research.
Drs Karen Assmann and Wilken-Jon von Appen are the solicited speakers for the session. Karen Assmann will be presenting on physical and ecological implications of Arctic Atlantification. Wilken-Jon von Appen will be talking about eddies in the Arctic Ocean.

Ocean ventilation is a process by which water properties imprinted by the atmosphere onto the upper ocean, such as oxygen, carbon dioxide and trace gases, are transported into the ocean interior. In mediating the exchange between the atmosphere and the ocean, ventilation plays an important role in both climate variability and biogeochemical cycles. This is manifested, for example, through the supply of oxygen to the ocean interior, transport and sequestration of nutrients, and the uptake and storage of anthropogenic carbon and heat in the ocean interior. Increased stratification - caused by the warming on the upper ocean under climate change - could lead to a reduction of ocean ventilation over the coming decades. However, the mechanism by which the changes in ocean ventilation will emerge, and their consequences for climate feedback, biogeochemical processes, and ocean ecosystems are not well known.
Developing our understanding of ocean ventilation is inhibited by the wide range of spatial scales inherent in the process, from small-scale mixing to basin scale. Robust projection of future change requires deeper insight into the processes driving ventilation, the spatial and temporal variability of ventilation, and the consequences and impacts of ventilation changes.
We invite contributions that advance understanding on the broad topic of ocean ventilation, its potential to change in a warming climate, and the consequences therein. We seek contributions that investigate both the physical processes involved in ocean ventilation — from small-scale mixing, to mesoscale stirring, to basin scale subduction — as well as the consequences for biogeochemical cycles and marine ecosystems. We welcome contributions from process-oriented studies as well as those that assess and quantify variability and projected changes, and welcome studies making use of observations, theory and/or numerical model.
The session is expected to be in a hybrid format, partly taking place in Vienna in a traditional format, and partly online.
This session provides a platform for interdisciplinary science addressing the continuum from the river source to the sea. A systems approach is indispensable for science-based solutions to sustainably manage complex River-Sea social-ecological systems. Studies linking environmental and social sciences and crossing geographical borders are particularly invited: from the river source and its catchment through estuaries, deltas and marshlands across the freshwater-marine water transition into the coastal sea, including surface-groundwater interaction. Studies addressing the impacts of climate change and extreme events and the impact of human activities on water and sediment quality and quantity, hydromorphology, biodiversity, ecosystem functioning and services of River-Sea continua are of particular interest.
We need to understand how River-Sea Systems function and to address many open questions. How are River-Sea continua changing due to human pressures? What is the impact of processes in the catchment on coastal and marine systems function, and vice versa? How can we discern between human-induced changes or those driven by natural processes from climate-induced variability and extreme events? What will the tipping points of social-ecological system states be and what will they look like? How can we better characterise river-sea systems from the latest generation Earth observation to citizen science based observatories. How can we predict short and long-term changes in River-Sea-Systems to manage them sustainably? What is the limit to which it is possible to predict the natural and human-influenced evolution of River-Sea-Systems? The increasing demand to balance intensive human use and environmental protection in River-Sea Systems requires holistic and integrative research approaches with the ultimate goal of enhanced system understanding as the knowledge base for sustainable management solutions.

Ocean-atmosphere flux exchanges of biogeochemically active constituents have significant impacts on global biogeochemistry and climate. Increasing atmospheric deposition of anthropogenically-derived nutrients (e.g., nitrogen, phosphorus, iron) to the ocean influences marine productivity and has associated impacts on oceanic CO2 uptake, and emissions to the atmosphere of climate active species (e.g., nitrous-oxide (N2O), dimethyl-sulfide (DMS), marine organic compounds and halogenated species). Atmospheric inputs of toxic substances (e.g., lead, mercury, cadmium, copper, persistent organic pollutants) into the ocean are also of concern for their impact on ocean ecosystem health. In recent decades the intensive use of plastics has led to significant levels of persistent micro- and nano- plastics being transported into the marine atmosphere and to the ocean, with considerable uncertainty remaining on transport pathways and oceanic impacts. Other influential recent changes include emission reductions for air pollution abatement which have resulted in changes in cloud and aerosol chemical composition, affecting atmospheric acidity, associated chemical processing and impacts via atmospheric deposition on ocean biogeochemistry.
In turn, oceanic emissions of reactive species and greenhouse gases influence atmospheric chemistry and global climate, and induce potentially important chemistry-climate feedbacks. While advances have been made by laboratory, field, and modelling studies over the past decade, we still lack understanding of many of the physical and biogeochemical processes linking atmospheric deposition of chemicals, nutrient availability, marine biological productivity, trace-gas sources and sinks and the biogeochemical cycles governing air-sea fluxes of these climate active species, as well as on the atmosphere-ocean cycle of microplastics and its impact on the environment and climate.
This session will address the above issues on the atmospheric deposition of nutrients and toxic substances to the ocean, the impacts on ocean biogeochemistry, and also the ocean to atmosphere fluxes of climate active species and potential feedbacks to climate. We welcome new findings from measurement programmes (laboratory, in-situ and remote sensing) and atmospheric and oceanic numerical models.

The United Nations has designated the 2020s as the decade of ecosystem restoration; and restoration of streams, rivers and their catchments is particularly important to restore ecosystems and halt biodiversity loss, in addition to achieving several sustainable development goals. Within Europe, river restoration is used to meet the EU Water Framework Directive objectives, and EU LIFE projects provide millions of euro per year to physical restoration. Furthermore, restoration of rivers and their catchments will prove both more important in the coming decades in order to mitigate and adapt to the effects of climate change and more challenging when restoring a moving target with altered flow, sediment, and ice regimes and habitat conditions. Restoration and management of rivers and their catchments will require a holistic view of multiple facets of river systems and will need to be process-based, including geomorphic, hydrological and ecological processes, incorporating an understanding of how these evolve and interact following restoration interventions. In addition, large wood (LW) is a key component of fluvial ecosystems and affects both flow and sediment transport processes. LW jams (i.e., logjams) can be used as a tool for river restoration increasing flow and bed heterogeneity. However, the transportation of LW may significantly increase during floods and LW jams can form at river infrastructure, creating an additional flood risk, which needs to be accounted for in management strategies of rivers. An interdisciplinary effort is required to improve our understanding of the complex interactions of wood with flow and sediment in fluvial ecosystems.
In this session we wish to highlight a broad range of research on methods, success/failure, and follow-up of river and catchment restoration and management. We are particularly interested in studies related to restoration with a changing baseline of climate conditions as well as aspects associated with LW; however, there are also many basic questions on how to manage and restore rivers that also need to be addressed, including time-to-recovery, resilience, relationships between different river facets, the impact of different spatial scales of restoration, etc. We hope this session will spark discussion among an interdisciplinary group of researchers of how to take into account a changing climatic baseline in future river restoration and evaluation of restoration success.
Coastal wetland ecosystems, such as salt marshes, mangroves, seagrass beds and tidal flats, are under increasing pressure from natural and anthropogenic processes shifting climatic conditions, and are declining in area and habitat quality globally. These environments provide numerous ecosystem services, including flood risk mediation, biodiversity provision and climate change mitigation through carbon storage. Hence, the need to get a deeper understanding of processes and interactions in these environments, and how these may be altered by climate change has never been greater. This is the case for ‘managed’, restored wetlands and natural systems alike.
This session will bring together studies of coastal wetland ecosystems across climates and geomorphic settings, to enhance the understanding of ecosystem service provisioning, interactions between hydrodynamics, sediment and ecology, and identify best future management practices. Studies of all processes occurring within coastal wetlands are invited. This includes, but is not exclusive to, sediment dynamics, hydrology, hydrodynamics, biogeochemistry, morphological characterisation, geotechnical analysis, bio-morphodynamics, ecological change and evolution, impact of climate change, sea level rise, anthropogenic and management implications. Experiences from wetlands restoration projects are welcomed to increase knowledge on how to achieve wetlands long-term resilience. Multidisciplinary approaches across spatial and temporal scales are encouraged, especially in relation to global climate change. This session aims to enhance our understanding of basic processes governing coastal wetland dynamics and to propose sustainable management solutions for contemporary environmental pressures.
Processes responsible for formation and development of the early Earth (> 2500Ma) are not well understood and strongly debated, reflecting in part the poorly preserved, altered, and incomplete nature of the geological record from this time.
In this session we encourage the presentation of new approaches and models for the development of Earth's early crust and mantle and their methods of interaction. We encourage contributions from the study of the preserved rock archive as well as geodynamic models of crustal and mantle dynamics so as to better understand the genesis and evolution of continental crust and the stabilization of cratons.
We invite abstracts from a large range of disciplines including geodynamics, geology, geochemistry, and petrology but also studies of early atmosphere, biosphere and early life relevant to this period of Earth history.

Modelling past climate states, and the transient evolution of Earth’s climate remains challenging. Time periods such as the Paleocene, Eocene, Pliocene, the Last Interglacial, the Last Glacial Maximum or the mid-Holocene span across a vast range of climate conditions. At times, these lie far outside the bounds of the historical period that most models are designed and tuned to reproduce. However, our ability to predict future climate conditions and potential pathways to them is dependent on our models' abilities to reproduce just such phenomena. Thus, our climatic and environmental history is ideally suited to thoroughly test and evaluate models against data, so they may be better able to simulate the present and make future climate projections.
We invite papers on palaeoclimate-specific model development, model simulations and model-data comparison studies. Simulations may be targeted to address specific questions or follow specified protocols (as in the Paleoclimate Modelling Intercomparison Project – PMIP or the Deep Time Model Intercomparison Project – DeepMIP). They may include anything between time-slice equilibrium experiments to long transient climate simulations (e.g. transient simulations covering the entire glacial cycle as per the goal of the PalMod project) with timescales of processes ranging from synoptic scales to glacial cycles and beyond. Comparisons may include past, historical as well as future simulations and focus on comparisons of mean states, gradients, circulation or modes of variability using reconstructions of temperature, precipitation, vegetation or tracer species (e.g. δ18O, δD or Pa/Th).
Evaluations of results from the latest phase of PMIP4-CMIP6 are particularly encouraged. However, we also solicit comparisons of different models (comprehensive GCMs, isotope-enabled models, EMICs and/or conceptual models) between different periods, or between models and data, including an analysis of the underlying mechanisms as well as contributions introducing novel model or experimental setups.

Scientific drilling through the International Ocean Discovery Program (IODP) and the International Continental Scientific Drilling Program (ICDP) continues to provide unique opportunities to investigate the workings of the interior of our planet, Earth’s cycles, natural hazards and the distribution of subsurface microbial life. The past and current scientific drilling programs have brought major advances in many multidisciplinary fields of socio-economic relevance, such as climate and ecosystem evolution, palaeoceanography, the deep biosphere, deep crustal and tectonic processes, geodynamics and geohazards. This session invites contributions that present and/or review recent scientific results from deep Earth sampling and monitoring through ocean and continental drilling projects. Furthermore, we encourage contributions that outline perspectives and visions for future drilling projects, in particular projects using a multi-platform approach.

Minerals are formed in great diversity under Earth surface conditions, as skeletons, microbialites, speleothems, or authigenic cements, and they preserve a wealth of geochemical, biological, mineralogical, and isotopic information, providing valuable archives of past environmental conditions. Interpreting these archives requires fundamental understanding of mineral formation processes, but also insights from the geological record.
In this session we welcome oral and poster presentations from a wide range of research of topics, including process-oriented studies in modern systems, the ancient rock record, experiments, computer simulations, and high-resolution microscopy and spectroscopy techniques. We intend to reach a wide community of researchers sharing the common goal of improving our understanding of the fundamental processes underlying mineral formation, which is essential to read our Earth’s geological archive.

Anthropogenic greenhouse-gas emissions are drastically shaping global climate, increasing temperatures and contributing to more frequent extreme weather events. Terrestrial ecosystem responses to climate change can induce a large feedback via the control of biogeochemical cycles, for instance by regulating carbon fluxes that are 10 times larger than human emissions. A large portion of carbon and nutrient cycling is controlled by soil processes, in which microorganisms play a central role. Soil microbial communities and their physiological traits are, in turn, influenced by both gradual climate changes and more extreme short-term weather events. Thus, understanding the impacts of climate on soil microbial communities and microbe-mediated processes is critical for improving predictions of the resistance and resilience of terrestrial ecosystems in the future.
This session aims to elucidate the impacts of different climate scenarios on soil microbial communities and biogeochemical cycling, and their feedback to climate change. We will focus on different aspects of climate change, ranging from gradual changes such as increasing atmospheric CO2 or temperature, to the effects of more extreme weather events such as heatwaves, drying-rewetting cycles or floods. We invite studies on the resilience and associated recovery dynamics of soil biota to the mentioned environmental disturbances, as well as on their resistance or adaptation mechanisms. Studies with a focus on links between microbial community composition and function, as well as interactions between soil microorganisms, plants and fauna, are particularly welcomed. We aim to connect researchers from different disciplines and to create a discussion platform to review the current state-of-the-art, identify knowledge gaps, share ideas, and tackle new challenges in the field.
Microbial hotspots in soils such as the rhizosphere, detritusphere, biopores, hyphasphere, aggregate surfaces, pore space and etc, are characterized by high activity and fast process rates resulting in accelerated turnover of soil organic matter and other microbial functions (e.g. nutrient mobilization, litter decomposition, respiration, organic matter stabilization, greenhouse gas emission, acidification, etc.). The intensity of microbial and SOM turnover as well as nutrient cycling in such hotspots is at least one order of magnitude higher than in the bulk soil.
This session invites contribution to: 1) Various aspects of microbial activity, interactions, communities composition and distribution in hotspots; 2) Factors influencing (micro)biological nutrient (re)cycling including biotic and abiotic controls (e.g. climatic extreme, warming, drought, etc) are strongly encouraged; 3) The session will also present and discuss new developments to assess the crucial microbial mechanisms that underpin biogeochemical processes in hotspots (e.g. approaches assessing the variability in soil activity within the soil matrix, notably focusing on microbial molecular analysis and imaging methods); 4) Combination of experimental and theoretical approaches to predict the fate and functions of microorganisms in hotspots are highly appreciated.

Large amounts of methane, one of the most important greenhouse gasses, are produced in marine and lacustrine systems – but the majority is also consumed in sediments and the water column before reaching the atmosphere. Understanding the fate of methane in the aquatic realm is still a major scientific challenge because it is governed by a vast diversity of geological, oceanographic/limnological and biological factors.
In this session we will discuss past, present and future controls on methane dynamics in marine and lacustrine systems. Within this overarching theme we welcome contributions related to the following topics:
- methane formation: from water rock interactions, to petroleum systems and microbial degradation processes
- methane sources: natural and man made seepage
- subsurface fluid flow and methane/hydrocarbon transport mechanisms
- gas hydrate and permafrost
- gas/bubble transport: from numerical modelling to (geophysical) imaging
- seasonality, diel variations, and other temporal constrains
- methane sinks: from microbes and biogeochemical pathways to physicochemical processes
- methane-derived carbonates and microbe-mineral interactions
- molecular/micro/macro fossils from paleo systems.
- new methodologies and proxies for the investigation of methane sources and sinks
Processes controlling the global cycles of volatiles (e.g., C, H, O, S) across reservoirs regulate planetary climate and habitability. Their cycling pathways and efficiency are dependent on numerous factors including the presence of liquid water and the tectonic mode; and involves the atmosphere, hydrosphere, crust, mantle and even the core.
On Earth, major volatile cycles are balanced to first order through ingassing and outgassing, mainly occurring at subduction zones, and major sites of volcanism (i.e., mid-ocean ridges and hotspots), respectively. In planetary interiors, volatiles are partitioned into the existing minerals, or stabilize minor phases such as diamond or various hydrous phases in the mantle and crust, something that directly influences the spatial distribution of melt formation as well as rock properties. Conversely, melt transport induces volatile exchanges between planetary reservoirs and favours outgassing. Outgassing, in turn, will regulate planetary climates, hence influencing the habitability.
The aim of this session is to bring together numerical, experimental and observational expertise from Earth and Planetary Sciences to advance the understanding of interior-atmosphere coupling and volatile exchange and evolution on Earth and terrestrial (exo)planets, as well as the role of those volatiles on the interior composition and dynamics. This session features contributions on topics including volatile cycling, melt and volatile transport, mineral-melt phase relations, geophysical detections, tectonic regimes, outgassing, atmospheric composition and planetary habitability.
Fluid flow in the Earth’s crust is driven by pressure gradients and temperature changes induced by internal heat. The expression of crustal fluid flow is associated with a range of structural and geochemical processes taking place in the basement but also in sedimentary covers forming the upper crust. Groundwater, hydrothermal brines and gases circulating in the subsurface interact with local structures across different tectonic and geological settings. Under near-lithostatic conditions fluids and rocks are expelled vertically to the near-surface featuring a variety of surficial geological phenomena ranging from hydrothermal systems to sedimentary and hybrid volcanism and cold seeps both on land and along continental margins. These vertical fluid flow expressions and piercement structures are characterized by complex sedimentary deformation and geochemical reactions where life can adapt to thrive in extremely harsh environments making them ideal windows to the deep biosphere. Several studies have shown that CO2- and CH4-dominaterd (or hybrid) vents played a key role in the evolution of our planet and the cycles of life during several geological eras. Furthermore, the elevated pore pressures often encountered in reservoirs at depth make piercements ideal natural laboratories to capture precursors of seismic events and dynamically triggered geological processes. Yet, the geochemical and geophysical processes associated with the evolution of these vertical fluid flow features and piercements remain poorly understood.
This session welcomes contributions from the community working at the interface between magmatic and sedimentary environments using geophysical, geochemical, microbial, geological, numerical and laboratory studies to promote a better understanding of modern and paleo fluid-driven systems in the upper crust. In particular we call for contributions from: 1) investigations of tectonic discontinuities pre-existing geological structures; 2) the geochemical reactions occurring at depth and at the surface including microbiological studies; 3) geophysical imaging and monitoring of fluid flow systems associated with vertical fluid expulsion at the upper crust; 4) experimental and numerical studies about fluid flow evolution; 5) studies of piercement dynamics related to climatic and environmental implications.
The biosphere and geology of a planet are intrinsically interlinked. The geological habitat of Earth has driven the origin and evolution of life and biology has dramatically changed the planets surface and mineralogy over the last 4 billion years. In our Solar System, there are a broad range of planets and moons with potential habitable environments, and future missions will aim to determine if these ever had life or have life today. Planets orbiting other stars have different spectral types and metallicities and thus different starting bulk compositions which may impact the origin and evolution of life on those worlds. This session will examine the interplay of biology, and more broadly, habitability, from a planetary perspective.

Remaining carbon budgets specify the maximum amount of CO2 that may be emitted while stabilizing warming at a particular level (such as the 1.5 °C target), and are thus of high interest to the public and policymakers. Estimates of the remaining carbon budget comes with associated uncertainties, which are accounted for with various methods. These uncertainties increase in relative terms as more ambitious targets are being considered, or as emission reductions continue to be delayed, making practical implementation of remaining carbon budgets challenging.
This session aims to further our understanding of the climate response under various emission scenarios, with particular interest in emission pathways entailing net-zero targets, with meeting various levels of warming. We invite contributions that use a variety of tools, including fully coupled Earth System Models, Integrated Assessment Models, or simple climate model emulators, that advance our knowledge of remaining carbon budgets and net-zero targets. .
We welcome studies exploring different aspects of climate change in response to future emissions. In addition to studies exploring carbon budgets and the TCRE framework, we welcome contributions on the zero emissions commitment, the governing mechanisms behind linearity of TCRE and its limitations, effects of different forcings and feedbacks (e.g. permafrost carbon feedback) and non-CO2 forcings (e.g. aerosols, and other non-CO2 greenhouse gases), estimates of the remaining carbon budget to reach a given temperature target (for example, the 1.5 °C warming level from the Paris Agreement), the role of pathway dependence and emission rate, the climate-carbon responses to different emission scenarios (e.g. SSP scenarios, idealized scenarios, or scenarios designed to reach net-zero emission level), and the behaviour of TCRE in response to artificial carbon dioxide removal from the atmosphere (i.e. CDR or negative emissions). Contributions from the fields of climate policy and economics focused on applications of carbon budgets and benefits of early mitigation are also encouraged.

In a fast-changing environment, earth’s ecosystems are facing multiple stressors compromising the provision of essential services for mankind, and the resiliency of the natural environment itself.
Climate change, water pollution and scarcity affect biodiversity, socio-economic and climate related vulnerabilities and as a consequence, water and food security and human health.
The recent European Green Deal aims at Europe becoming the world’s first climate-neutral continent by 2050 and it does so by setting climate, energy, transport and taxation policies fit for reducing net greenhouse gas emissions by at least 55% by 2030. This program sets ambitious yet realistic targets for the next decades, auspicating the transformation of European Countries into a modern resource-efficient economy and society in line with the Sustainable Development Goals.
However, to address both the impacts as well as the causes of climate change, it is fundamental to create conditions where ecosystem services are optimized for both the local population and global objectives. Yet, the use of ecosystem services assessment in decision making might prove challenging when it comes to economic and social domains, as well as the perception and concept of natural environment may differ across disciplines. Such transdisciplinary approach plays a key role in Nature Based Solutions and opens up to the participation of multiple stakeholders in local governance, thus offering a multitude of co-benefits for the environment and for communities.
This session aims at opening a common ground between the natural, physical, social and economic sciences towards a resilient planet, by providing examples of challenges and opportunities and harmonizing best practices in this field.
We welcome transdisciplinary contributions on terrestrial, marine, and urban ecosystem services assessment that take into account the natural and the human dimension, advance in modelling complex spatio-temporal and social dynamics and transdisciplinary approaches towards nature inspired and supported solutions for social benefits and ecosystems’ resilience.

Perhaps the most dramatic demonstration of the impact of global environmental change has been the rapid change in fire regimes, from the Amazon to suburban Athens. However, the observed disruption in global wildfire regimes has not yet been directly attributed to climate – but only to weather patterns that make wildfires more likely.
At the heart of this issue is a lack of understanding of the diverse socio-ecological feedbacks that are driving Anthropocene wildfires. For example, in response to damaging fire events, common policy responses such as increased suppression and fire use bans may ultimately exacerbate fire risk by leading to large build-ups of flammable and connected fuels. Meanwhile a combination of global-scale trade conflict, national-scale political change and regional drought have all contributed to a surge in wildfires in the Amazon basin. These examples highlight the urgent need for new transdisciplinary approaches to wildfire research that account for feedbacks between land use and wider environmental change.
In this session we welcome a broad range of contributions that explore the interactions between socio-economic and biophysical drivers of wildfires, encompassing disciplines including: anthropology, earth observation, ecology, economics, land surface and climate modelling, and political science. Example topics might include how agricultural intensification, land degradation and CO2 fertilisation effects combine to alter fire regimes in grassland ecosystems, through to how rural and urban populations’ contrasting perceptions of risk can influence land management policies.
We particularly encourage contributions that demonstrate how methods from different disciplines may inform each other. Holistic advances in our understanding can lead to better adaptation policies and strategies, and will be vital to improved wildfire modelling and attribution of fire regime changes to climate change.

The virus is still with us, with more potent variants. It remains the most immediate challenge for geosciences and health, including its impacts on geoscience development (data collection, training, dissemination) and the achievement of the UN Sustainable Development Goals, in particular that urban systems should increase well-being and health.
Long-term visions based on transdisciplinary scientific advances are therefore essential. As a consequence, this session, like the ITS1.1 session in 2021, calls for contributions based on data-driven and theory-based approaches to health in the context of global change. This includes :
- main lessons from lockdowns?
- how to get the best scientific results during a corona pandemic?
- how to manage field works, geophysical monitoring and planetary missions?
- qualitative improvements in epidemic modelling, with nonlinear, stochastic, and complex system science approaches;
- eventual interactions between weather and/or climate factors and epidemic/health problems
- new surveillance capabilities (including contact tracing), data access, assimilation and multidimensional analysis techniques;
- a fundamental revision of our urban systems, their greening and their need for mobility;
- a special focus on urban biodiversity, especially to better manage virus vectors;
- urban resilience must include resilience to epidemics, and therefore requires revisions of urban governance.

Rationale
The proper and deep education on ethical issues in geosciences has been evolving in recent times, although not as quickly and deeply as necessary. Many of the professionals dedicated to Earth Sciences have been not in touch with such new concepts and tendencies. Geoethics is the research and reflection on the values that underpin appropriate behaviors and practices, wherever human activities interact with the Earth system. It provides a framework to define ethical professional behaviors in Earth sciences and engineering and to determine how these should be put into practice for the benefit of environment and society. The Short Course is directed towards introducing and training Earth scientists in those new concepts and ideas as well as exposing the perspectives of this field. Social-ecological Systems and the anthropic impact on land, ocean, and atmosphere are at the cores issues to be discussed under the umbrella of geoethics, as a tool to cope with Climate Changes and other earth-society related challenges.
Completing this course, participants
1. Will know the basic principles of ethics and how these lead to geoethics
2. Will be aware of the dilemmas involved in making geoethical decisions

A very tiny layer holds most of earth’s life in a complex mix of biotic and abiotic factors that interact in a subtle unique and ever changing play. In this scene, remotely-sensed (RS) signals result from the interaction of incoming, reflected and emitted electromagnetic radiation (EM) with atmospheric constituents, vegetation layers, soil surfaces, oceans or water bodies. Vegetation, soil and water bodies are functional interfaces between terrestrial ecosystems and the atmosphere. These signals can be measured by optical, thermal and microwave remote sensing including parts of the EM spectrum where fluorescence can be measured.
This session solicits for contributions on strategies, methodologies or approaches leading to the development and assimilation in models, of remote sensing products originating from different EM regions, angular constellations, fluorescence as well as data measured in situ for validation purposes.
We welcome presentations on topics related to climate change, food production, food security, nature preservation, biodiversity, epidemiology, anthropogenic and biogenic air pollution. Insights on the assimilation of remote sensing and in-situ measurements in bio-geophysical and atmospheric models, as well as RS extraction techniques themselves, are also welcome.
Finally, this session aim, is to bring together scientists developing remote sensing techniques, products and models leading to strategies with a higher bio-geophysical impact on the stability and sustainability of this very thin layer of the earth we live in.

One of the big challenges in Earth system science consists in providing reliable climate predictions on sub-seasonal, seasonal, decadal and longer timescales. The resulting data have the potential to be translated into climate information leading to a better assessment of global and regional climate-related risks.
The latest developments and progress in climate forecasting on subseasonal-to-decadal and longer timescales will be discussed and evaluated. This will include presentations and discussions of predictions for the different time horizons from dynamical ensemble and statistical/empirical forecast systems, as well as the aspects required for their application: forecast quality assessment, multi-model combination, bias adjustment, downscaling, exploration of artificial-intelligence methods, etc.
Following the new WCRP strategic plan for 2019-2029, prediction enhancements are solicited from contributions embracing climate forecasting from an Earth system science perspective. This includes the study of coupled processes between atmosphere, land, ocean, and sea-ice components, as well as the impacts of coupling and feedbacks in physical, chemical, biological, and human dimensions. Contributions are also sought on initialization methods that optimally use observations from different Earth system components, on assessing and mitigating the impacts of model errors on skill, and on ensemble methods.
We also encourage contributions on the use of climate predictions for climate impact assessment, demonstrations of end-user value for climate risk applications and climate-change adaptation and the development of early warning systems.
A special focus will be put on the use of operational climate predictions (C3S, NMME, S2S), results from the CMIP5-CMIP6 decadal prediction experiments, and climate-prediction research and application projects.
An increasingly important aspect for climate forecast's applications is the use of most appropriate downscaling methods, based on dynamical or statistical approaches or their combination, that are needed to generate time series and fields with an appropriate spatial or temporal resolution. This is extensively considered in the session, which therefore brings together scientists from all geoscientific disciplines working on the prediction and application problems.

Land–atmosphere interactions often play a decisive role in shaping climate extremes. As climate change continues to exacerbate the occurrence of extreme events, a key challenge is to unravel how land states regulate the occurrence of droughts, heatwaves, intense precipitation and other extreme events. This session focuses on how natural and managed land surface conditions (e.g., soil moisture, soil temperature, vegetation state, surface albedo, snow or frozen soil) interact with other components of the climate system – via water, heat and carbon exchanges – and how these interactions affect the state and evolution of the atmospheric boundary layer. Moreover, emphasis is placed on the role of these interactions in alleviating or aggravating the occurrence and impacts of extreme events. We welcome studies using field measurements, remote sensing observations, theory and modelling to analyse this interplay under past, present and/or future climates and at scales ranging from local to global but with emphasis on larger scales.

Proper characterization of uncertainty remains a major research and operational challenge in Environmental Sciences, and is inherent to many aspects of modelling impacting model structure development; parameter estimation; an adequate representation of the data (inputs data and data used to evaluate the models); initial and boundary conditions; and hypothesis testing. To address this challenge, methods for a) uncertainty analysis (UA) that seek to identify, quantify and reduce the different sources of uncertainty, as well as propagating them through a system/model, and b) the closely-related methods for sensitivity analysis (SA) that evaluate the role and significance of uncertain factors (in the functioning of systems/models), have proved to be very helpful.
This session invites contributions that discuss advances, both in theory and/or application, in methods for SA/UA applicable to all Earth and Environmental Systems Models (EESMs), which embraces all areas of hydrology, such as classical hydrology, subsurface hydrology and soil science.
Topics of interest include (but are not limited to):
1) Novel methods for effective characterization of sensitivity and uncertainty
2) Analyses of over-parameterised models enabled by AI/ML techniques
3) Single- versus multi-criteria SA/UA
4) Novel approaches for parameter estimation, data inversion and data assimilation
5) Novel methods for spatial and temporal evaluation/analysis of models
6) The role of information and error on SA/UA (e.g., input/output data error, model structure error, parametric error, regionalization error in environments with no data etc.)
7) The role of SA in evaluating model consistency and reliability
8) Novel approaches and benchmarking efforts for parameter estimation
9) Improving the computational efficiency of SA/UA (efficient sampling, surrogate modelling, parallel computing, model pre-emption, model ensembles, etc.)
Vadose zone hydrology studies the physical processes in the unsaturated zone. Modeling and observation of soil and vadose zone processes aims at characterizing soil properties and quantifying terrestrial water storage dynamics. The states of soil, air and water affect biogeochemical processes, vegetation water availability, nutrient and pollutant transport at local scale, catchment response functions and rainfall-runoff processes at intermediate scale, land-atmosphere interaction and land-climate feedbacks at the continental scale. Advanced measurement techniques, increased availability of high-frequency data, and the need for terrestrial system understanding challenges vadoze zone modeling concepts, budging model parameterizations from static to near dynamic. This session aims to bring together scientists advancing the current status in modelling soil and vadose zone processes from the pore to the catchment and continental scale. Contributions to this session address soil hydrological processes, characterization of soil properties and soil hydraulic properties, soil biogeochemical processes and their interactions with hydrology, transport of pollutants, and soil vegetation atmosphere modelling.

This Short Course is aimed at researchers in climate-related domains, who have an interest in working with climate data. We will introduce the ESMValTool, a Python project developed to facilitate the analysis of climate data through so-called recipes. An ESMValTool recipe specifies which input data will be used, which preprocessor functions will be applied, and which analytics should be computed. As such, it enables readable and reproducible workflows. The tool takes care of finding, downloading, and preparing data for analysis. It includes a suite of preprocessing functions for commonly used operations on the input data, such as regridding or computation of various statistics, as well as a large collection of established analytics.
In this course, we will run some of the available example recipes using ESMValTool’s convenient Jupyter notebook interface. You will learn how to customize the examples, in order to get started with implementing your own analysis. A number of core developers of ESMValTool will be present to answer any and all questions you may have.
The ESMValTool has been designed to analyze the data produced by Earth System Models participating in the Coupled Model Intercomparison Project (CMIP), but it also supports commonly used observational and re-analysis climate datasets, such as ERA5. Version 2 of the ESMValTool has been specifically developed to target the increased data volume and complexity of CMIP Phase 6 (CMIP6) datasets. ESMValTool comes with a large number of well-established analytics, such as those in Chapter 9 of the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) (Flato et al., 2013) and has been extensively used in preparing the figures of the Sixth Assessment Report (AR6). In this way, the evaluation of model results can be made more efficient, thereby enabling scientists to focus on developing more innovative methods of analysis rather than constantly having to "reinvent the wheel".

The geological record provides insight into how climate processes operate and evolve in response to different than modern boundary conditions and forcings. Understanding deep-time climate evolution is paramount to progressing on understanding fundamental questions of Earth System feedbacks and sensitivity to perturbations, such as the behaviour of the climate system under elevated atmospheric CO2 levels—relative to the Quaternary—, or the existence of climatic tipping points and thresholds. In recent years, geochemical techniques and Earth System Models complexity have been greatly improved and several international projects on deep-time climates (DeepMIP, MioMIP, PlioMIP) have been initiated, helping to bridge the gap between palaeoclimate modelling and data community. This session invites work on deep-time climate simulations and proxy-based reconstructions from the Cambrian to the Pliocene. We especially encourage submissions featuring palaeoenvironmental reconstructions, palaeoclimate modelling, and the integration of proxies and models of any complexity.
Reconstructing the climates of past interglacials could improve our understanding and projections of future climate change. Notable examples of past interglacial variability include high sea levels during MIS11c, peak CO2 and CH4 levels during MIS9e and high temperatures over Antarctica during MIS5e. Interestingly, it appears that there is not a single interglacial in the last 800,000 years that experienced the warmest temperatures, the highest sea levels and the most elevated greenhouse-gas concentrations. Moreover, there are substantial differences between interglacials in ocean circulation, sea ice, vegetation, carbon cycle and regional climate. Indeed, when comparing various past interglacials, the variability between them is striking; hence the term interglacial diversity (Tzedakis et al., Nature, 2009). If we want to understand interglacial climate change, we need to understand what causes such diversity.
We therefore invite submissions that explore the characteristics of interglacial diversity. Moreover, we seek to understand the potential drivers of interglacial diversity, for instance insolation changes, the impact of the preceding deglaciation or modes of variability internal to the Earth system. We are particularly interested in new proxy records, compilations of existing data from a range of archives and new theoretical concepts or model experiments that can help to explain the observations. This session will bring together proxy-based, theoretical and/or modelling studies and targets the broader Earth system including changes in climate, ice sheets and the carbon cycle.

The pacing of the global climate system by orbital variations is clearly demonstrated in the timing of e.g. glacial-interglacial cycles. The mechanisms that translate this forcing into geoarchives and climate changes continue to be debated. We invite submissions that explore the climate system response to orbital forcing, and that test the stability of these relationships under different climate regimes or across evolving climate states (e.g. mid Pleistocene transition, Pliocene-Pleistocene transition, Miocene vs Pliocene, and also older climate transitions). Submissions exploring proxy data and/or modelling work are welcomed, as this session aims to bring together proxy-based, theoretical and/or modelling studies focused on global and regional climate responses to astronomical forcing at different time scales in the Phanerozoic.

Ice sheets play an active role in the climate system by amplifying, pacing, and potentially driving global climate change over a wide range of time scales. The impact of interactions between ice sheets and climate include changes in atmospheric and ocean temperatures and circulation, global biogeochemical cycles, the global hydrological cycle, vegetation, sea level, and land-surface albedo, which in turn cause additional feedbacks in the climate system. This session will present data and modelling results that examine ice sheet interactions with other components of the climate system over several time scales. Among other topics, issues to be addressed in this session include ice sheet-climate interactions from glacial-interglacial to millennial and centennial time scales, the role of ice sheets in Cenozoic global cooling and the mid-Pleistocene transition, reconstructions of past ice sheets and sea level, the current and future evolution of the ice sheets, and the role of ice sheets in abrupt climate change.
This session aims to showcase an exciting diversity of state-of-the-art advances in all aspects of Phanerozoic (Cambrian to Quaternary) stratigraphy, paleoceanography, and paleoclimatology. We invite case studies of organic and inorganic geochemistry, sedimentology, and paleontology from marine and terrestrial environments, as well as multidisciplinary and modeling studies. An emphasis is placed upon the use of a variety of tools for deciphering sedimentary records and their stratigraphy across intervals of major environmental change. We further invite contributions that provide insight into the evolution of the Earth on short and long timescales, including climate perturbations and their consequences.

What role did climate dynamics play in human evolution, the dispersal of different Homo species within and beyond the African continent, and key cultural innovations? Were dry spells, stable humid conditions, or rapid climate fluctuations the main driver of human evolution and migration? In order to evaluate the impact that different timescales and magnitudes of climatic shifts might have had on the living conditions of prehistoric humans, we need reliable and continuous reconstructions of paleoenvironmental conditions and fluctuations from the vicinity of paleoanthropological and archaeological sites. The search for the environmental context of human evolution and mobility crucially depends on the interpretation of paleoclimate archives from outcrop geology, lacustrine and marine sediments. Linking archeological data to paleoenvironmental reconstructions and models becomes increasingly important.
As a contribution towards a better understanding of these human-climate interactions the conveners encourage submission of abstracts on their project’s research on (geo)archaeology, paleoecology, paleoclimate, stratigraphy, and paleoenvironmental reconstructions. We especially welcome contributions offering new methods for dealing with difficult archive conditions and dating challenges. We hope this session will appeal to a broad audience by highlighting the latest research on paleoenvironmental reconstructions in the vicinity of key sites of human evolution, showcasing a wide variety of analytical methods, and encouraging collaboration between different research groups. Conceptual models, modelling results and model-data comparisons are warmly welcomed, as collaborative and interdisciplinary research.

Tree rings are one of nature’s most versatile archives, providing insight into past environmental conditions at annual and intra-annual resolution and from local to global scales. Besides being valued proxies for historical climate, tree rings are also important indicators of plant physiological responses to changing environments and of long-term ecological processes. In this broad context we welcome contributions using one or more of the following approaches to either study the impact of environmental change on the growth and physiology of trees and forest ecosystems, or to assess and reconstruct past environmental change: (i) dendrochronological methods including studies based on tree-ring width, MXD or Blue Intensity, (ii) stable isotopes in tree rings and related plant compounds, (iii) dendrochemistry, (iv) quantitative wood anatomy, (v) ecophysiological data analyses, and (vi) mechanistic modelling, all across temporal and spatial scales.

Speleothems and other continental carbonates (e.g. travertines, pedogenic, lacustrine, subglacial and cryogenic carbonates) are important terrestrial archives, which can provide precisely dated, high-resolution records of past environmental and climate changes. The field of carbonate-based paleoclimatology has seen (1) continuously improving analytical capacity, supporting the compilation of detailed records of climate variability integrating established as well as novel and innovative techniques. (2) Long-term environmental monitoring campaigns facilitating the interpretation of high-resolution proxy time series from carbonate archives. (3) The continuous development of proxy-system models that can help understand the measured proxies, by describing processes such as water infiltration, carbonate dissolution, precipitation and diagenesis. (4) The development of proxy databases such as SISAL (Speleothem Isotope Synthesis and AnaLysis) which enable regional-to-global scale analysis of the relationship between the proxy and the environmental parameter using a variety of large data analysis and data-model comparison techniques.
Applied together, advancements in these cornerstones pave the way towards developing highly reliable and quantitative terrestrial climate reconstructions. This session aims to bring together integrated and interdisciplinary studies in order to better understand the precipitation environment of continental carbonates and the incorporation of climate-sensitive proxies at various time scales. We especially invite contributions that show progress in one of the four outlined domains, and welcome speleothem and carbonate-based modern and paleoenvironmental studies, including new records of past climatic changes. In addition, research contributing to current international co-ordinated activities, such as the PAGES working group on Speleothem Isotopes Synthesis and AnaLysis (SISAL) and others are welcome.

The Sahara is widely recognised as the largest hot desert and the largest single source of mineral dust on the planet. Over the Quaternary it has periodically transformed through natural processes to a vegetated landscape capable of supporting flora and fauna and scattered human populations that are mostly absent today. This remarkable ‘greening’ was driven by variations in Earth’s orbit around the Sun and resultant changes in the hydrological cycle, and was probably maintained by a range of feedbacks in the land-atmosphere-ocean system. Several critical research questions rely on a full understanding of these African Humid Periods (AHPs). For example, it remains to be shown whether the AHPs supported the migration of early hominids out of Africa. AHPs are thought to have terminated abruptly, and so a full characterisation of how these phases evolved is crucial for understanding abrupt climate change dynamics. AHPs also turn out to be a very stringent test of Earth System models (ESMs), with implications for how well ESMs can represent these regions under future conditions.
This session aims to bring together researchers from a range of backgrounds to share and discuss the latest findings around greening events in the Sahara as well as potential links with future climate change. We hope to foster interdisciplinary collaboration and motivate further research in this topic area. We welcome contributions based on archaeological findings, palaeoclimate reconstructions, Earth System modelling or climate theory. Abstracts that combine these fields or that focus on links with present-day and/or future climate in this region are also encouraged.

The half-century since the first deep ice core drilling at Camp Century, Greenland, has seen extensive innovation in methods of ice sample extraction, analysis and interpretation. Ice core sciences include isotopic diffusion analysis, multiple-isotope systematics, trace gases and their isotopic compositions, ice structure and physical properties, high-resolution analysis of major and trace impurities, and studies of DNA and radiochemistry in ice, among many others. Many climate and geochemical proxies have been identified from ice cores, with ongoing effort to extend their application and refine their interpretation. Great challenges remain in the field of ice coring sciences, including the identification of suitable sites for recovery of million-year-old ice; spatial integration of climate records (e.g. PAGES groups Antarctica2k and Iso2k); and deeper understanding of glaciological phenomena such as streaming flow, folding of layers and basal ice properties. This session welcomes all contributions reporting the state-of-the-art in ice coring sciences, including drilling and processing, dating, analytical techniques, results and interpretations of ice core records from polar ice sheets and mid- and low-latitude glaciers, remote and autonomous methods of surveying ice stratigraphy, and related modelling research.

This session aims to place recently observed climate change in a long-term perspective by highlighting the importance of paleoclimate research spanning the past 2000 years. We invite presentations that provide insights into past climate variability, over decadal to millennial timescales, from different paleoclimate archives (ice cores, marine sediments, terrestrial records, historical archives and more). In particular, we are focussing on quantitative temperature and hydroclimate reconstructions, and reconstructions of large-scale modes of climate variability from local to global scales. This session also encourages presentations on the attribution of past climate variability to external drivers or internal climate processes, data syntheses, model-data comparison exercises, proxy system modelling, and novel approaches to producing multi-proxy climate field reconstructions.

Arid to sub-humid regions are home for >40% of the world’s population, and many prehistoric and historic cultures developed in these regions. Due to the high sensitivity of drylands to small-scale environmental changes and anthropogenic activities, ongoing geomorphological processes but also the Late Quaternary geomorphological and palaeoenvironmental evolution as recorded in sediment archives are becoming increasingly relevant for geological, geomorphological, palaeoenvironmental, palaeoclimatic and geoarchaeological research. Dryland research is constantly boosted by technological methodological advances, and especially by emerging linkages with other climatic and geomorphic systems that allow using dryland areas as indicator-regions of global environmental changes.
This session aims to pool contributions that deal with current and former geomorphological processes and environmental changes, as well as with all types of sediment archives in dryland areas (dunes, loess, slope deposits, fluvial sediments, alluvial fans, lake and playa sediments, desert pavements, soils, palaeosols etc.) at different spatial and temporal scales. Besides case studies from individual regions and archives and review studies, methodical and conceptual contributions are especially welcome in this session, e.g. dealing with the special role of aeolian, fluvial, gravitational and biological processes in dryland environments, sediment preservation, methods to obtain chronological frameworks and process rates, emerging geo-technologies and the role of such processes for current and former societies.

The radiation budget of the Earth is a key determinant for the genesis and evolution of climate on our planet and provides the primary energy source for life. Anthropogenic interference with climate occurs first of all through a perturbation of the Earth radiation balance. We invite observational and modelling papers on all aspects of radiation in the climate system. A specific aim of this session is to bring together newly available information on the spatial and temporal variation of radiative and energy fluxes at the surface, within the atmosphere and at the top of atmosphere. This information may be obtained from direct measurements, satellite-derived products, climate modelling as well as process studies. Scales considered may range from local radiation and energy balance studies to continental and global scales. In addition, related studies on the spatial and temporal variation of cloud properties, albedo, water vapour and aerosols, which are essential for our understanding of radiative forcings, feedbacks, and related climate change, are encouraged. Studies focusing on the impact of radiative forcings on the various components of the climate system, such as on the hydrological cycle, on the cryosphere or on the biosphere and related carbon cycle, are also much appreciated.

Large-scale atmospheric circulation dynamics are the major driver of near surface climatic and environmental variability. Synoptic climatology examines atmospheric circulation dynamics and their relationship with near surface environmental variables. Within synoptic climatological analyses, a wide variety of methods is utilized to characterize atmospheric circulation (e.g., circulation and weather type classifications, regime analysis, teleconnection indices). Various linear and non-linear approaches (e.g., multiple regression, canonical correlation, neural networks) are applied to relate the circulation dynamics to diverse climatic and environmental elements (e.g., air temperature, air pollution, floods).
The session welcomes contributions from the whole field of synoptic climatology. This includes application studies focusing on various regions, time periods and target variables. In particular, we welcome contributions on development and comparison of methods (e.g., varying circulation type classifications) and conceptual approaches (e.g., circulation types versus circulation regimes).

This session explores climate change, extremes, processes and their impacts at local to regional scales, and the tools employed to investigate these phenomena. In particular, we welcome submissions advancing the state-of-the-art in the development and application of high-resolution models (convection-permitting, grid spacing ≤ 4 km) and high-resolution sub-daily data sets. Other high-resolution data sets such as land-surface, vegetation or similar, and their impacts on local-scale climate change and extremes, are of further interest.
The session aims to bring together, amongst others, numerical modellers, the observational community and CORDEX-FPS participants, with the aim of advancing understanding of the aforementioned topics. Of particular interest are any new insights which are revealed through high-spatiotemporal-resolution modelling or data sets. For example: convective extremes, physical mechanisms, fine-scale and feedback processes, differences in climate change signal, scale-dependency of extremes, interactions across scales and land-atmosphere interactions. Further, we welcome studies that explore local-scale climate change in a variety of contexts whether they be past, present or future change.
Additional topics include, though are not limited to:
-- Mesoscale convective systems and medicanes
-- Event-based case studies (including surrogate climate change experiments or attribution)
-- Approaches for quantifying uncertainty at high resolutions including multi-model ensemble and combined dynamical-statistical approaches
-- High-resolution winds and their impacts
-- Convection, energy balance and hydrological cycle including vegetation
-- Model setup and parametrization, including sensitivity to resolution, land surface and dynamics
-- Tropical convection and convective processes at local to regional scale
-- Model evaluation and new evaluation metrics/methods

Changes in seasonal timing affect species and ecosystem response to environmental change. Observations of plant and animal phenology as well as remote sensing and modeling studies document complex interactions and raise many open questions.
We invite contributions with cross-disciplinary perspectives that address seasonality changes based on recent plant and animal phenological observations, pollen monitoring, historical documentary sources, or seasonality measurements using climate data, remote sensing, flux measurements or modeling studies. Contributions across all spatial and temporal scales are welcome that compare and integrate seasonality changes, study effects of long-term climate change or single extreme events, emphasize applications and phenology informed decision-making, discuss species interactions and decoupling, advance our understanding of how seasonality change affects carbon budgets and atmosphere/biosphere feedbacks, and integrate phenology into Earth System Models.
We emphasize phenology informed applications for decision-making and environmental assessment, public health, agriculture and forest management, mechanistic understanding of the phenological processes, and effects of changing phenology on biomass production and carbon budgets. We also welcome contributions addressing international collaboration and program-building initiatives including citizen science networks and data analyses.

Observations and model simulations illustrate significant ocean variability and associated air-sea interactions in the tropical Atlantic basin from daily-to-decadal time scales. This session is devoted to the understanding of ocean dynamics in the tropical and subtropical Atlantic Ocean, its interaction with the overlying atmosphere from the equator to the mid-latitudes and its climate impacts on adjacent to remote areas. Relevant processes in the ocean include upper and deep ocean circulation, eddies, tropical instability waves, warm pools, cold tongues and eastern boundary upwellings. We are interested in air-sea interactions related to both the seasonal cycle and the development of modes of variability from local to basin scale (e.g. the Meridional Mode, the Atlantic Niño, and the Benguela Niño). We welcome studies on wind variations related to the development of these modes, as well as studies on high-frequency events, such as marine heat waves, the Madden-Julian Oscillation, tropical cyclones and convective systems. Furthermore, we seek studies on climate change in the region, and also of the climatic impacts of change and variability on marine ecosystems. Finally, we are also interested in contributions examining the causes and impacts of systematic model errors in simulating the local to regional Atlantic climate. Studies based on direct observations, reanalysis, reconstructions as well as model simulations are welcome.

The Indian Ocean is unique among the other tropical ocean basins due to the seasonal reversal of monsoon winds and concurrent ocean currents, lack of steady easterlies that result in a relatively deep thermocline along the equator, low-latitude connection to the neighboring Pacific and a lack of northward heat export due to the Asian continent. These characteristics shape the Indian Ocean’s air-sea interactions, variability, as well as its impacts and predictability in tropical and extratropical regions on (intra)seasonal, interannual, and decadal timescales. They also make the basin particularly vulnerable to anthropogenic climate change, as well as related extreme weather and climate events, and their impacts for surrounding regions, which are home to a third of the global population. Advances have recently been made in our understanding of the Indian Ocean’s circulation, interactions with adjacent ocean basins, and its role in regional and global climate. Nonetheless, significant gaps remain in understanding, observing, modeling, and predicting Indian Ocean variability and change across a range of timescales.
This session invites contributions based on observations, modelling, theory, and palaeo proxy reconstructions in the Indian Ocean that focus on recent observed and projected changes in Indian Ocean physical and biogeochemical properties and their impacts on ecological processes, diversity in Indian Ocean modes of variability (e.g., Indian Ocean Dipole, Indian Ocean Basin Mode, Madden-Julian Oscillation) and their impact on predictions, interactions and exchanges between the Indian Ocean and other ocean basins, as well as links between Indian Ocean variability and monsoon systems across a range of timescales. In particular, we encourage submissions on weather and climate extremes in the Indian Ocean, including marine heatwaves and their ecological impacts. We also welcome contributions that address research on the Indian Ocean grand challenges highlighted in the recent IndOOS Decadal Review, and as formulated by the Climate and Ocean: Variability, Predictability, and Change (CLIVAR), the Sustained Indian Ocean Biogeochemistry and Ecosystem Research (SIBER), the International Indian Ocean Expedition 2 (IIOE-2), findings informed by the Coupled Model Intercomparison Project version 6 (CMIP6) on past, present and future variability and change in the Indian Ocean climate system, and contributions making use of novel methodologies such as machine learning.

Traditionally, hydrologists focus on the partitioning of precipitation water on the surface, into evaporation and runoff, with these fluxes being the input to their hydrologic models. However, more than half of the evaporation globally comes back as precipitation on land, ignoring an important feedback of the water cycle if the previous focus applied. Land-use and water-use changes, as well as climate variability and change alter, not only, the partitioning of water but also the atmospheric input of water as precipitation, related with this feedback, at both remote and local scales.
This session aims to:
i. investigate the remote and local atmospheric feedbacks from human interventions such as greenhouse gasses, irrigation, deforestation, and reservoirs on the water cycle, precipitation and climate, based on observations and coupled modelling approaches,
ii. investigate the use of hydroclimatic frameworks such as the Budyko framework to understand the human and climate effects on both atmospheric water input and partitioning,
iii. explore the implications of atmospheric feedbacks on the hydrologic cycle for land and water management.
Typically, studies in this session are applied studies using fundamental characteristics of the atmospheric branch of the hydrologic cycle on different scales. These fundamentals include, but are not limited to, atmospheric circulation, humidity, hydroclimate frameworks, residence times, recycling ratios, sources and sinks of atmospheric moisture, energy balance and climatic extremes. Studies may also evaluate different sources of data for atmospheric hydrology and implications for inter-comparison and meta-analysis. For example, observations networks, isotopic studies, conceptual models, Budyko-based hydro climatological assessments, back-trajectories, reanalysis and fully coupled earth system model simulations.

In the current context of global change, assessing the impact of climate variability and changes on hydrological systems and water resources is increasingly crucial for society to better-adapt to future shifts in water resources, as well as extreme conditions (floods and droughts). However, important sources of uncertainty have often been neglected in projecting climate impacts on hydrological systems, especially uncertainties associated with internal/natural climate variability, whose contribution to near-future changes could be as important as forced anthropogenic climate changes at the regional scales. Internal climate modes of variability (e.g. ENSO, NAO, AMO) and their impact on the continent are not always properly reproduced in the current global climate models, leading to large underestimations of decadal climate and hydro-climatic variability at the global scale. At the same time, hydrological response strongly depends on catchment properties, whose interactions with climate variability are little understood at the decadal timescales. These factors altogether significantly reduce our ability to understand long-term hydrological variability and to improve projections and reconstructions of future and past hydrological changes upon which improvement of adaption scenarios depends.
We welcome abstracts capturing recent insights for understanding past or future impacts of large-scale climate variability on hydrological systems and water resources as well as newly developed projection and reconstruction scenarios. Results from model intercomparison studies are encouraged.
Mountains cover approximately one quarter of the total land surface on the planet, and a significant fraction of the world’s population lives in their vicinity. Orography critically affects weather and climate processes at all scales and, in connection with factors such as land-cover heterogeneity, is responsible for high spatial variability in mountain weather and climate. Due to this high complexity, monitoring and modeling the atmosphere and the other components of the climate system in mountain regions is challenging both at short (meteorological) and long (climatological) time-scales. This session is devoted to the better understanding of weather and climate processes in mountain and high-elevation areas around the globe, as well as their modification induced by global environmental change.
We welcome contributions describing the influence of mountains on the atmosphere on meteorological time-scales, including terrain-induced airflow, orographic precipitation, land-atmosphere exchange over mountains, forecasting and predictability of mountain weather.
Contributions connected with the TEAMx research programme (http://www.teamx-programme.org/) are encouraged.
Furthermore, we invite studies that investigate climate processes and climate change in mountain areas and its impacts on dependent systems, based on monitoring and modeling activities. Particularly welcome are contributions that merge various sources of information and reach across disciplinary borders (atmospheric, hydrological, cryospheric, ecological and social sciences) and that connect to the Elevation-Dependent Climate Change (EDCC) working group of the Mountain Research Initiative (see https://www.mountainresearchinitiative.org/activities/community-led-activities/working-groups).

Chemistry and aerosols play a major role in determining surface air quality, the Earth’s energy budget, and climate change. Conversely, climate change affects atmospheric abundances of trace gases and aerosols through composition-climate interactions. This session focuses on global scale atmospheric chemistry and aerosol modelling, radiative forcing, and climate change through the historical period and into the future.
A better understanding of the role of natural aerosols in the atmosphere is essential for assessing climate changes. Our session explores primary aerosols and those formed from precursor gases emitted by natural sources, e.g. from wildfires, deserts, volcanoes, oceans, and vegetation. The session intends to bring together experts from different fields to assess the state-of-the-science knowledge on natural aerosols and to identify future directions to reduce uncertainty in their emissions and impacts. We encourage submissions that use models across different spatial scales and consider past, present or future perspectives, as well as measurements from remote sensing, field campaigns and laboratory experiments.
In particular, it aims to bring together scientists with an interest in:
1. Evaluating reactive gases and aerosols in models against observations
2. Quantifying the impact of emissions changes on atmospheric composition
3. Exploring chemistry-climate interactions in models, with a focus on climate feedbacks involving trace gases and aerosols
4. Quantifying radiative forcing and the climate response to changes in trace gas and aerosol concentrations
5. Distinguishing between truly natural aerosols and those whose emissions or formation are influenced by anthropogenic activities
6. Missing links in our understanding of the lifecycle of natural aerosols
7. The time evolution of contributions of natural aerosols to atmospheric composition and deposition
8. The consequences of changes in natural aerosols
The session welcomes contributions from those currently involved in analysis of recent and ongoing CMIP6 experiments focusing on the areas above,

Soil organic matter (SOM) is well known to exert a great influence on physical, chemical, and biological soil properties, thus playing a very important role in agronomic production and environmental quality. Globally SOM represents the largest terrestrial organic C stock, which can have significant impacts on atmospheric CO2 concentrations and thus on climate. The changes in soil organic C content are the result of the balance of inputs and losses, which strongly depends on the processes of organic C stabilization and protection from decomposition in the soil. This session will provide a forum for discussion of recent studies on the transformation, stabilization and sequestration mechanisms of organic C in soils, covering any physical, chemical, and biological aspects related to the selective preservation and formation of recalcitrant organic compounds, occlusion by macro and microaggregation, and chemical interaction with soil mineral particles and metal ions.

To address societal concerns over rising sea level and extreme events, understanding the contributions behind these changes is key to predict potential impacts of sea level change on coastal communities and global economy, and is recognized as one of the Grand Challenges of our time by the World Climate Research Programme (WCRP). To continue this discussion, we welcome contributions from the international sea level community that improve our knowledge of the past and present changes in global and regional sea level, extreme events, and flooding, and produce improved predictions of their future changes.
We welcome studies on various drivers of sea level change and linkages between variability in sea level, heat and freshwater content, ocean dynamics, land subsidence from natural versus anthropogenic influences, and mass exchange between the land and the ocean associated with ice sheet and glacier mass loss and changes in the terrestrial water storage. Studies focusing on future sea level changes are also encouraged, as well as those discussing potential short-, medium-, and long-term impacts on coastal and deltaic environments, as well as the global oceans.

Detecting and attributing anthropogenic climate change in long-term observed climatic trends is an active area of research, seeking to identify ongoing changes in the climate system, and to quantify the contributions of various external forcing to these changes. Attributable trends, as well as a variety of other emerging constraints, can also be used to constrain climate projections. This science is better established for temperature related variables than for other climate indicator including hydrometeorological variables.
Complementary to this, assessing the extent to which extreme weather events, including compound events, are attributable to anthropogenic climate change is a rapidly developing science, with emerging schools of thought on the methodology and framing of such studies. Once again, the attribution of hydrometeorological events, is less straightforward than temperature-related events. The attribution of impacts, both for long-term trends and extreme events is even more challenging.
This session solicits the latest studies from the spectrum of detection and/or attribution approaches. By considering studies over a wide range of temporal and spatial scales we aim to identify common/new methods, current challenges, and avenues for expanding the detection and attribution community. We particularly welcome submissions that compare approaches, address hydrometerological trends, extremes, impacts, and/or assess implications of recent trends in terms of future changes – all of which test the limits of the present science.

This session merges CL3.1.3 “Climate change and other drivers of environmental change: Developments, interlinkages and impacts in regional seas and coastal regions” focused on regional seas and coastal regions worldwide, and CL3.1.4 “Climate change in Mediterranean-type climate regions” focused on the Mediterranean-type climates, with a very similar scope: how climate change and other drivers affect these regions now and in the future.
Regional climate change interacts with many other man-made perturbations in both natural and anthropogenic coastal environments. Regional climate change is one of multiple drivers, which have a continuing impact on terrestrial, aquatic and socio-economic (resp. human) environments. These drivers interact with regional climate change in ways, which are not completely understood.
A Mediterranean-type climate is characterized by mild, wet winters and hot, dry summers as classified with the Koppen-Geiger approach that is well suited for identifying and analyzing the impacts of climate change on natural and anthropic ecosystems. Mediterranean climate regions (MCRs) are located in transitional midlatitude regions like the Mediterranean basin area, western coastal North America and small coastal areas of western South America, southern Africa and southern Australia. The transitional character with sharp spatial gradients makes them highly vulnerable to climate change. For all MCRs, the future holds high risks and uncertainty on issues like loss in biodiversity, increase in aridity, ecological change, requiring innovative approaches to climate adaptation and mitigation.
This session focuses on the connections and interrelations between climate change and other drivers of environmental change in MCRs, regional seas and coastal regions. It intends to strengthen the exchanges among the communities involved to better understand and share commonalities and differences and to provide an overview of the current state of knowledge of the complicated interplay of different factors affecting climate change. This exchange may help identify and prepare shared solutions and practices. Studies focused on physical (including extremes, teleconnections, hydrological cycle) and biogeochemical (including biodiversity) aspects of Mediterranean and other coastal climate regions, focusing on observed past changes, future climate projections, as well as related social aspects including indigenous knowledge in mitigating climate risks will be treated.
The Earth’s subsurface hosts enormous methane volumes trapped in geologic reservoirs, gas hydrates and permafrost, locally escaping the sediment at cold seeps to enter the hydrosphere/atmosphere.
Such environments are highly sensitive to climate change. Despite an increasing awareness about the positive feedback between global warming and methane seepage, the response of these complex and dynamic systems to climate change is still unclear due to complex geo/hydro/atmosphere interactions.
Fossil cold seeps, long-term observatory studies and modern examples form the foundations to understand the mutual dependences between climate and seepage, and to develop robust models to forecast future scenarios at the Earth-system scale. For this session, we welcome geologists, geophysicists, geochemists, biologists, model developers, and any others who have contributed to new case studies in modern and fossil hydrocarbon seeps in the marine and terrestrial environment, gas hydrate and permafrost settings, to describe both new methods/technologies and the scientific outcomes.
It becomes increasingly accepted that many regions all over the world are experiencing an increase in the frequency of extreme rainfall events and potentially in their properties. For predicting the impact of future climate change on the landscape, it is therefore vital to understand the dynamics of surface processes under extreme events. Furthermore, focusing on the conditions necessary for extreme events to occur can provide key insights into past changes in climate at different time scales. Extreme storms cause a multitude of hydrogeomorphic and natural hazards responses, including floods and respective fluvial responses, hillslope erosion and failures, and debris flows from slopes into fluvial systems. Measuring, evaluating, and predicting the impacts of extreme rainstorms, however, remains challenging due to the difficult-to-predict and complex nature of storms and rainfall-surface interactions.
This interdisciplinary session focuses on the causative chain which links the deterministic and mostly stochastic nature of the synoptic to meso/regional and watershed scales of extreme storms, to their respective transformation into watershed, slope, and stream hydrology, and to their geomorphic impact. We welcome studies from all the parts of this chain, from all climates, and at all temporal scales, that are focusing on the hydrological responses to extreme events and on their imprints on the landscape through erosion and sediment movement. We favor studies with emphasis on the final noticeable impact of extreme events on the landscape and/or on the integrated long-term consequences of extreme storm regime on landscape evolution. Especially, we encourage studies presenting new physical/stochastic modeling approaches that explicitly investigated the impact of extreme events on the landscape.

As the most evident example of land use and land-cover change, urban areas play a fundamental role in local to large-scale planetary processes, via modification of heat, moisture, and chemical budgets. With rapid urbanization ramping up globally it is essential to recognize the consequences of landscape conversion to the built environment. Given the capability of cities to serve as first responders to global change, considerable efforts are currently being dedicated across many cities to monitor and understand urban atmospheric dynamics and examine various adaptation and mitigation strategies aimed to offset impacts of rapidly expanding urban environments and influences of large-scale greenhouse gas emissions.
This session solicits submissions from both the observational and modelling communities examining urban atmospheric and landscape dynamics, processes and impacts owing to urban-induced climate change, the efficacy of various strategies to reduce such impacts, and techniques highlighting how cities are already using novel science data and products that facilitate planning and policies on urban adaptation to and mitigation of the effects of climate change. Emerging topics including, but not limited to, compounding impacts with urban COVID-19 outbreaks, citizen science and crowdsourcing, or urban-climate informatics, are highly encouraged.

Remaining carbon budgets specify the maximum amount of CO2 that may be emitted while stabilizing warming at a particular level (such as the 1.5 °C target), and are thus of high interest to the public and policymakers. Estimates of the remaining carbon budget comes with associated uncertainties, which are accounted for with various methods. These uncertainties increase in relative terms as more ambitious targets are being considered, or as emission reductions continue to be delayed, making practical implementation of remaining carbon budgets challenging.
This session aims to further our understanding of the climate response under various emission scenarios, with particular interest in emission pathways entailing net-zero targets, with meeting various levels of warming. We invite contributions that use a variety of tools, including fully coupled Earth System Models, Integrated Assessment Models, or simple climate model emulators, that advance our knowledge of remaining carbon budgets and net-zero targets. .
We welcome studies exploring different aspects of climate change in response to future emissions. In addition to studies exploring carbon budgets and the TCRE framework, we welcome contributions on the zero emissions commitment, the governing mechanisms behind linearity of TCRE and its limitations, effects of different forcings and feedbacks (e.g. permafrost carbon feedback) and non-CO2 forcings (e.g. aerosols, and other non-CO2 greenhouse gases), estimates of the remaining carbon budget to reach a given temperature target (for example, the 1.5 °C warming level from the Paris Agreement), the role of pathway dependence and emission rate, the climate-carbon responses to different emission scenarios (e.g. SSP scenarios, idealized scenarios, or scenarios designed to reach net-zero emission level), and the behaviour of TCRE in response to artificial carbon dioxide removal from the atmosphere (i.e. CDR or negative emissions). Contributions from the fields of climate policy and economics focused on applications of carbon budgets and benefits of early mitigation are also encouraged.

Understanding the impact of climate change on natural and socio-economic outcomes plays an important role in informing a range of national and international policies, including energy, agriculture and health. However economic models of (and those designed to include) climate impacts that guide decision makers rely on multiple components, for example projections of future climate change, damage functions, and policy responses, each of which comes with its own modelling challenges and uncertainties.
We invite research using process-based (e.g., Integrated Assessment Models) and empirical models of climate change to investigate future human and natural impacts, together with policy evaluation to explore effective mitigation, technology and adaptation pathways. Furthermore, we invite research on changes to, and new developments of climate-economic and econometric modelling.

In 2015, the UN Sustainable Development Goals and the Paris Agreement on climate recognized the deteriorating resilience of the Earth system, with planetary-scale human impacts constituting a new geological epoch: the Anthropocene. Earth system resilience critically depends on the nonlinear interplay of positive and negative feedbacks of biophysical and increasingly also socio-economic processes. These include dynamics and interactions between the carbon cycle, the atmosphere, oceans, large-scale ecosystems, and the cryosphere, as well as the dynamics and perturbations associated with human activities.
With rising anthropogenic pressures, there is an increasing risk we might be hitting the ceiling of some of the self-regulating feedbacks of the Earth System, and cross tipping points which could trigger large-scale and partly irreversible impacts on the environment, and impact the livelihood of millions of people. Potential domino effects or tipping cascades could arise due to the interactions between these tipping elements and lead to a further decline of Earth resilience. At the same time, there is growing evidence supporting the potential of positive (social) tipping points that could propel rapid decarbonization and transformative change towards global sustainability.
In this session we invite contributions on all topics relating to tipping points in the Earth system, positive (social) tipping, as well as their interaction and domino effects. We are particularly interested in various methodological approaches, from Earth system modelling to conceptual modelling and data analysis of nonlinearities, tipping points and abrupt shifts in the Earth system.

Agriculture is an important sector of any economy of the world. Agriculture productions are highly dependent on the climate change and variability. Changes in hydro-meteorological variables can influence crop yield and productivity at many places. Further, climate change can influence nutrient levels, soil moisture, water availability and other terrestrial parameters related to the agricultural productivity. Changes in the frequency and severity of droughts and floods could pose challenges for farmers and ranchers and threaten food safety. Further, changes in climate can influence meteorological conditions and thus can influence the crop growth pattern. It may also influence irrigation scheduling and water demand of the crops. The effects of climate change also need to be considered along with other evolving factors that affect agricultural production, such as changes in farming practices and technology.
The purpose of the proposed session is to gather scientific researchers related to this topic aiming to highlight ongoing researches and new applications in the field of climate change and agriculture. In this framework, original works concerned with the development or exploitation of advanced techniques for understanding the impact of climate change on agriculture will be invited.
The conveners of this session will encourage both applied and theoretical research in this area.

Extreme climate and weather events, associated disasters and emergent risks are becoming increasingly critical in the context of global environmental change and interact with other stressors. They are a potential major threat to reaching the Sustainable Development Goals (SDGs) and one of the most pressing challenges for future human well-being.
This session explores the linkages between extreme climate and weather events, associated disasters, societal dynamics and resilience. Emphasis is laid on 1) Which impacts are caused by extreme climate events (including risks emerging from compound events) and cascades of impacts on various aspects of ecosystems and societies? 2) Which feedbacks across ecosystems, infrastructures and societies exist? 3) What are key obstacles towards societal resilience and reaching the SDGs, while facing climate extremes? 4) What can we learn from past experiences? 5) What local to global governance arrangements best support equitable and sustainable risk reduction?
We welcome empirical, theoretical and modelling studies from local to global scale from the fields of natural sciences, social sciences, humanities and related disciplines.

With recent extreme events reaching far beyond existing records, such as the Pacific Northwest heat wave and severe flooding in Western Europe, eastern US and across China, the discussion to what extent we are prepared for unprecedented extremes and whether existing methods and models are able to capture them has flared up. It is becoming increasingly essential to understand and quantify plausible rare, high-impact events for risk management and adaptation.
Methods to understand and evaluate low-likelihood extreme events have seen substantial advancements over the recent years. Event attribution studies are now providing rapid analyses of unprecedented extreme events; physical climate storylines are developed to evaluate plausible rather than likely events; causal inference is used to understand drivers of very rare events; near-miss events and potential analogues in space, historical and paleo archives are evaluated; spatial extreme value analysis and machine learning methods are applied, large ensembles representing various outcomes are generated, such as Single Model Initial-condition Large Ensembles (SMILEs); and weather prediction systems are increasingly being employed, such as the through the UNprecedented Simulated Extremes using ENsembles (UNSEEN) approach.
This session aims to bring together communities from weather prediction, climate projection, hydrology to impact and risk management, and to learn from the variety of methods to understand and quantify low-likelihood extreme events in the present and future climate. The session welcomes contributions at all temporal and spatial scales, and all types of extremes and invites novel methods – including downward counterfactuals and causal inference – as well as new results on unforeseen climate risks – including those from compound events and low-likelihood high-warming outcomes.

Climate change is debated most often for its environmental and socioeconomic repercussions; however, it also has a dramatic impact on tangible cultural heritage worldwide. The safeguard and fruition of cultural assets – outdoors or indoors, and either on land, underground, or underwater – are jeopardized by the current and expected environmental changes. The behavior of the component materials varies likewise, in response to global warming, sea level rise, ocean acidification, and the increase of extreme weather events.
This session addresses the climate change risk to cultural heritage from the interdisciplinary perspective of geosciences, which represent a valuable support for investigating the properties and durability of the materials (e.g., stones, ceramics, mortars, pigments, glasses, and metals); their vulnerability and the changes in weathering dynamics; the key environmental variables (pertaining to climate, microclimate, air pollution, water and soil composition) and the effects of extreme events; the techniques and products to improve conservation practices; and the adaptation measures for heritage protection. This session welcomes contributions based on approaches including but not limited to field and laboratory analysis and testing; damage assessments and simulations; modelling of risk scenarios and decay trends; strategies of monitoring and remote investigation; and processing of environmental databases.

The current scientific consensus links climate change to devastating consequences for society including natural hazards, heatwaves, floods, droughts and hurricanes. Yet, potential solutions requiring collaboration between communities, local actors and scientists continue to face considerable structural, spatial, temporal and definitional challenges.
Structural challenges: Political and micro-political aspects and how they interact with structural inequalities are important to understand vulnerability and the disproportionate impacts of climate change induced extreme events.
Spatial challenges: At the local level, providing usable information for people is challenging particularly in the poorest regions of the world. While hazards can be explored with weather and climate data. overall risk can only be assessed by balancing location-specific information and data which is often inaccessible or under researched.
Temporal challenge: Often climate change impacts have not been monitored consistently or according to the best available science and data. Particularly in the global South and developing economies, these temporal challenges make effective adaptation challenging.
Definitional challenge: vulnerability across time-space is defined in diverse ways. Many approaches tend to use hazard, exposure and vulnerability interchangeably. Whereas the assessment of local vulnerability is only possible by combining natural and social sciences with stakeholder engagement, prevailing interventions miss one or the other resulting in limited possibility for project sustainability Furthermore, a universal conceptualization or approach to vulnerability is yet to be presented.
Local adaptation solutions to these challenges do exist and could be used as models to be transferred to other regions. For example, UNESCO-designated sites such as Biosphere Reserves and UNESCO Global Geoparks provide solutions for climate change mitigation and adaptation based on inclusive, transparent, and empowering governance processes, in line with sustainable development.
We welcome research on locally produced and scientifically robust solutions to these structural, spatial, temporal and definitional challenges. Particularly abstracts focusing on 1) the quantification of hazards, risks, and impacts that matter for the identified community, 2) conceptual frameworks and tools to assess vulnerability and exposure, 3) approaches to monitor impacts and 4) case studies that showcase local solutions.

This session investigates mid-latitude cyclones and storms on both hemispheres. We invite studies considering cyclones in different stages of their life cycles from the initial development, to large- and synoptic-scale conditions influencing their growth to a severe storm, up to their dissipation and related socioeconomic impacts.
Papers are welcome, which focus also on the diagnostic of observed past and recent trends, as well as on future storm development under changed climate conditions. This will include storm predictability studies on different scales. Finally, the session will also invite studies investigating impacts related to storms: Papers are welcome dealing with vulnerability, diagnostics of sensitive social and infrastructural categories and affected areas of risk for property damages. Which risk transfer mechanisms are currently used, depending on insured and economic losses? Which mechanisms (e.g. new reinsurance products) are already implemented or will be developed in order to adapt to future loss expectations?

Climate change (CC) and ocean degradation (OD) are among the greatest threats to humanity. Climate impacts the ocean in massive ways; the ocean is the climate’s most powerful regulator. Separately or combined, they impact every living being and ecological niche, with poorer communities suffering disproportionately. In turn, flora and fauna (incl humans) are suffering. CC and OD are affecting the cryosphere, biodiversity, and food and water security. Given that humans are the prime cause of this devastating change taking us beyond our planetary boundaries, geoethical issues come to the fore.
The 2020 EGU Declaration of the Significance of Geoscience highlights the need for massive and widespread action to help people around the world to become literate about the changes affecting their and their offsprings’ and communities’ lives. The more people are literate about these changes, the more they can make informed decisions, adapt and mitigate. Previous General Assemblies have addressed climate change literacy (CL). Ocean literacy (OL) has developed strongly in recent years, especially with impetus from the UN Ocean Decade. Ocean-climate literacy (OCL) is an imperative that needs to be addressed massively and urgently, both within and beyond the EGU.
We invite colleagues to submit contributions on any aspects of OCL; this can, of course, include CL (without the ocean) and OL (without the climate). We welcome papers related, eg, to learning processes/experiences, instructional materials, curricular innovation, learning games, citizen initiatives, Ocean Decade activities, evaluation, well-used methods, novel approaches and policies, eg, 1. make OCL an essential component in all subjects and at all levels of education; 2. require all people in positions of responsibility (eg, mayors, teachers, doctors, CEOs, ministers, et al) to pass exams on the basics of climate and/or ocean before taking office. Of particular interest are literacy actions that bring in geoethical dimensions. (If your paper is primarily on geoethics, then a better home is the EGU session on geoethics.) The broad aims of such OCL might include encouraging an intergenerational outlook, developing a sense of the geoethical dimensions of OCL, understanding complexities and implementing solutions.
This session is an opportunity for ECSs, scientists, educators, policy influencers, learning resource developers and other practitioners to share their experience, expertise and research on CL and OL.

This session aims to share innovative approaches to developing multi-hazard risk assessments and their components (hazard, exposure, vulnerability and capacity), and to explore their applications to disaster risk reduction.
Effective disaster risk reduction practices and the planning of resilient communities requires the evaluation of multiple hazards and their interactions. This approach is endorsed by the UN Sendai Framework for Disaster Risk Reduction. Multi-hazard risk and multi-hazard impact assessments look at interaction mechanisms among different natural hazards, and how spatial and temporal overlap of hazards influences the exposure and vulnerability of elements at risk. Moreover, the uncertainty associated with multi-hazard risk scenarios needs to be considered, particularly in the context of climate change and slow-onset hazards, such as Covid-19 and pandemics in general, characterized by dynamic changes in exposure and vulnerability that are challenging to quantify.
This session, therefore, aims to profile a diverse range of multi-hazard risk and impact approaches, including hazard interactions, multi-vulnerability studies, and multi-hazard exposure characterization. In covering the whole risk assessment chain, we propose that it will be easier to identify potential research gaps, synergies and opportunities for future collaborations.
We encourage abstracts which present innovative research, case study examples and commentary throughout the whole disaster risk cycle on (i) multi-hazard risk methodologies which address multi-vulnerability and multi-impact aspects; (ii) methodologies and tools for multi-hazard risk management and inclusive risk-informed decision making and planning; (iii) methodologies and tools for multi-hazard disaster scenario definition and management for (near) real-time applications; (iv) cross-sectoral approaches to multi-hazard risk, incorporating the physical, social, economic, and/or environmental dimensions; (v) uncertainty in multi-hazard risk and multi-hazard impact assessment; (vi) evaluation of multi-hazard risk under future climate and slow-onset hazards, including pandemics; (vii) implementation of disaster risk reduction measures within a multi-hazard perspective.

Climate impact and adaptation research has made considerable progress in various fields in the recent years. However, the concrete implementation on the ground needs to be improved.
Local decision makers are facing several challenges with regard to climate adaptation. At the center of this process lies the coupling of climate, impact and risk (incl. vulnerability) models in order to identify future climate risk levels. Finding and correctly using the necessary data in climate impacts and risks assessments and planning for climate action is not without challenges for specialists from other fields.
While climate modelling and technical integration of diverse model data are crucial, social science as well as interdisciplinary perspectives are essential to assess local adaptation capacities, the costs and benefits of adaptive measures and to ensure the usability and transferability of the climate services. Similarly important is capacity building and trainings on properly using, interpreting and communicating climate and impact information.
This session touches upon innovative ways to address theses challenges. It also supports exchange on experiences in impact and adaptation studies, using all kinds of climate data. Former participants from the C3S ULS and IS-ENES3 training events are particularly encouraged to join.
This session discusses approaches and challenges towards the support of climate change adaptation and disaster risk reduction. Central to the discussion is the question how such services can be developed in a stringent co-design process that integrates different natural and social science disciplines as well as users and practitioners. We are therefore seeking for contributions that discuss:
• Actionable services for regional decision-making in regional climate adaptation and disaster risk reduction and challenges in the interaction between researchers and decision makers
• New scientific insights into regional climate and impact modelling (data interfaces and harmonization)
• Assessing local climate adaptation capacities and measures in an integrated way
• New insights into transdisciplinary processes in climate change adaptation
• Data availability for climate impact studies and methods for dealing with limited data availability as well as the opposite, a large number of seemingly similar datasets.
• Experiences with existing tools or newly developed tools for data processing
Global warming is unequivocal: the frequency and intensity of heavy precipitation events increased since the mid-20th century in all regions in which observational data were sufficient for trend analysis. And heavy precipitations and related effects are projected to intensify and be more frequent in most regions.
In this framework, particular attention should be paid to all the ground events triggered by rainfall, among which landslides and soil erosion.
Changes in temperature also have been shown to affect the hydraulic and mechanical behavior of soils and rocks in multiple ways, suggesting the importance of monitoring and modelling thermal variables alongside the hydraulic ones.
The influence of climate variables on the triggering, frequency, and severity of slope failures and soil erosion can be different according to the area, the time horizon of interest, and the specific trends of weather variables. Similarly, land use/cover change can play a pivotal role in exacerbating or reducing such hazards.
Thus, the overall impacts depend on the region, spatial scale, time frame, and socio-economic context addressed. However, even the simple identification of the weather patterns regulating the occurrence of such phenomena represents a not trivial issue, also assuming steady conditions, due to the crucial role played by geomorphological details. To support hazards’ monitoring, predictions, and projections, last-generation and updated datasets with high spatio-temporal resolution and quality - as those from the Copernicus Services’ Portals - are useful to feed models, big-data analytics, and indicators’ frameworks enabling timely, robust, and efficient decision making.
The Session aims at presenting studies concerning ongoing to future analysis on the impact of climate change on landslide triggering and dynamics, and soil erosion hazard, across different geographical contexts and scales. Either investigations including analyses of historical records and related climate variables, or modeling approaches driven by future climate exploiting downscaled output of climate projections are welcome. Studies assessing variations in severity, frequency, and/or timing of events and consequent risks are valuable.
Moreover, a focus on all aspects of landslide thermo-hydro-mechanics, from experimental studies to field and remote-sensing monitoring, from microstructural analyses to geomechanical modelling at various spatial and temporal scales, is proposed.
Land use and land cover change (LULCC), including land management, has the capacity to alter the climate by disrupting land-atmosphere fluxes of carbon, water and energy. Thus, there is a particular interest in understanding the role of LULCC as it relates to climate mitigation and adaptation strategies. Much attention has been devoted to the biogeochemical impacts of LULCC, yet there is an increasing awareness that the biogeophysical mechanisms (e.g. changes in surface properties such as albedo, roughness and evapotranspiration) should also be considered in climate change assessments of LULCC impacts on weather and climate. However, characterizing biogeophysical land-climate interactions remains challenging due to their complexity. If a cooling or a warming signal emerges depends on which of the biogeophysical processes dominates and on the size and pattern of the LULCC perturbation. Recent advances exploiting Earth system modelling and Earth observation tools are opening new possibilities to better describe LULCC and its effects at multiple temporal and spatial scales. This session invites studies that improve our general understanding of climate perturbations connected to LULCC from both biogeophysical and biogeochemical standpoints, and particularly those focusing on their intersection. This includes studies focusing on LULCC that can inform land-based climate mitigation and adaptation policies. Both observation-based and model-based analyses at local to global scales are welcome.

Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

Nature-Based Solutions and Climate Engineering in Climate Governance
As reaching the Paris agreement goal of limiting the global mean surface warming even below 2ºC becomes increasingly difficult with only emission reduction, additional measures complementing greenhouse gas (GHG) emission reductions to limit global warming gain more attention: Nature-based Solutions and Climate Engineering.
Nature-based solutions (NbS) have gained popularity as a set of integrated approaches that contribute to climate change adaptation, slowing further global warming, supporting ecosystem services and biodiversity, while promoting sustainable development. To achieve the full potential of NbS to address climate change, there is an urgent need for multidisciplinary teams of scientists to articulate solutions that engage policy makers and enable NbS interventions to reduce carbon emissions while benefiting human well-being. This will require systemic change in the way we conduct research, promote collaboration between institutions and with policy makers.
Climate Engineering (CE) is much more controversial. Carbon Dioxide Removal (CDR) aims at removing CO2 from the atmosphere through techniques such as ocean fertilization, artificial upwelling or enhanced weathering. CE has been criticized for creating potentially dangerous side effects, distracting from the root cause of climate change (GHG emissions), and being difficult to govern. So what, if any, should be the future role of CDR and SRM in the climate governance toolbox and to what extent should CE research have high priority? which knowledge gaps must be addressed before a decision for or against these techniques can be taken?
This session aims to advance knowledge of innovative NbS approaches for more inclusive and resilient communities from inter-disciplinary perspectives.
Specific topics include, but are not limited to:
— Benefits: The potential of NbS and CE to help achieving climate goals
— Feasibility: Tools and best practices enabling successful implementation and upscaling of NbS; impact assessment of real-life NbS projects, especially for the Global South and developing countries; and technical feasibility and risks in implementing CE
— Viability: Cost-benefit analysis of NbS and CE to multiple Sustainable Development Goals
— Governance: New NBS governance models and co-creation approaches and tools; and regional and global challenges and solutions for fair and inclusive governance of CE.

The proper management of blue and green water is vital for sustainable livelihoods in drylands (i.e. hyper—arid, arid, semi—arid and dry sub—humid lands), where any productive activity is structurally and deeply related to the understanding of soil hydrological behaviour. In these areas groundwater is usually the primary source for drinking water supply and irrigation so that water management is critical to the water-food-energy security nexus.
Irrigation, in particular, should be regarded as a fundamental element of any agroecosystem and an effective defence against desertification. This as a consequence of the fact that on one hand traditional irrigation is often a cultural heritage, which requires to be faced with an interdisciplinary approach, while on the other hand incorrect irrigation techniques may lead to soil and groundwater salinization, with dramatic fallout on agricultural productivity.
Also, due to local shifts in climate and in the hydrological cycle, or global changes such as population growth and changes in land use, drylands and regions with high water stress are expected to expand globally: for example, catchments in Central Europe with continental climate and decreasing precipitation in summer periods are likely to be new areas subjected to water stress.
This session welcomes contributions ranging from the understanding of the soil hydrological behaviour and of the mass fluxes through the soil in drylands and environments under stress conditions to the identification of the consequences of a changing environment for better future management, protection, and sustainable use of water resources in drylands.
This includes adapted modelling techniques coupling climate models with hydrological models or with soil water and groundwater models, or studies dealing with groundwater quantity and quality, the interaction between irrigation and soil hydrology, and the design of irrigation systems in arid districts and oases, also involving non—conventional waters (e.g. water harvesting). Particular attention will be given to traditional irrigation techniques as well as to precision irrigation techniques, also with local community involvement.
Due to a frequently associated data scarcity issue in dry regions, methodologies and strategies addressing uncertainty and limited data availability are of interest for this session. Interdisciplinary contributions and contributions from appropriate field observational studies are encouraged as well.

The virus is still with us, with more potent variants. It remains the most immediate challenge for geosciences and health, including its impacts on geoscience development (data collection, training, dissemination) and the achievement of the UN Sustainable Development Goals, in particular that urban systems should increase well-being and health.
Long-term visions based on transdisciplinary scientific advances are therefore essential. As a consequence, this session, like the ITS1.1 session in 2021, calls for contributions based on data-driven and theory-based approaches to health in the context of global change. This includes :
- main lessons from lockdowns?
- how to get the best scientific results during a corona pandemic?
- how to manage field works, geophysical monitoring and planetary missions?
- qualitative improvements in epidemic modelling, with nonlinear, stochastic, and complex system science approaches;
- eventual interactions between weather and/or climate factors and epidemic/health problems
- new surveillance capabilities (including contact tracing), data access, assimilation and multidimensional analysis techniques;
- a fundamental revision of our urban systems, their greening and their need for mobility;
- a special focus on urban biodiversity, especially to better manage virus vectors;
- urban resilience must include resilience to epidemics, and therefore requires revisions of urban governance.

Land–atmosphere interactions often play a decisive role in shaping climate extremes. As climate change continues to exacerbate the occurrence of extreme events, a key challenge is to unravel how land states regulate the occurrence of droughts, heatwaves, intense precipitation and other extreme events. This session focuses on how natural and managed land surface conditions (e.g., soil moisture, soil temperature, vegetation state, surface albedo, snow or frozen soil) interact with other components of the climate system – via water, heat and carbon exchanges – and how these interactions affect the state and evolution of the atmospheric boundary layer. Moreover, emphasis is placed on the role of these interactions in alleviating or aggravating the occurrence and impacts of extreme events. We welcome studies using field measurements, remote sensing observations, theory and modelling to analyse this interplay under past, present and/or future climates and at scales ranging from local to global but with emphasis on larger scales.

Adapting to climate change in the Mediterranean region represents a key socio-economic and environmental challenge. Different levels of exposure and vulnerability as well as different projected changes characterize the Mediterranean region. Understanding the past, characterizing the present and modelling the future are therefore essential steps to estimate the risks, assess the impacts of climate change, and identify potential adaptation and mitigation strategies. This multidisciplinary MedCLIVAR session encourages contributions from a broad range of disciplines and topics, e.g. dealing with: dynamics and processes of the climate system; sectoral impacts of climate change; climate change adaptation and mitigation; innovative methods and approaches in climate science. The session focuses on all time scales from paleoclimate to future model projections as well as on all relevant socio-economic sectors.

An increasing number of single model large ensemble simulations from Global Climate Models (GCM), Earth System Models (ESM), or Regional Climate Models (RCM) have been generated over recent years, to investigate internal variability and forced changes of the climate system — and to aid the interpretation of the observational record by providing a range of historical climate trajectories that could have been. The increased availability of large ensembles also enables new and inter-disciplinary applications beyond large-scale climate dynamics.
This session invites studies using large GCM, ESM, or RCM ensembles looking at the following topics: 1) Reinterpretation of the observed record in light of internal variability; 2) forced changes in internal variability; 3) development of new approaches to attribute and study observed events or trends; 4) impacts of natural climate variability; 5) assessment of extreme and compound event occurrence; 6) combining single model large ensembles with CMIP archives for robust decision making; 7) large ensembles as testbeds for method development.
We welcome research across all components of the Earth system. Examples include topics ranging from climate dynamics, hydrology and biogeochemistry to research on the role of internal variability in impact studies, focused for example on agriculture, air pollution or energy generation and consumption. We particularly invite studies that apply novel methods or cross-disciplinary approaches to leverage the potential of large ensembles.

Analysis of the energy transfers between and within climate components has been at the core of many step changes in the understanding of the climate system. Large-scale atmospheric circulation, hydrological cycle and heat/moisture transports are tightly intertwined through radiative and heat energy absorption and transports that are sensitive to multiple forcings and feedbacks. Cross-equatorial energy exchanges by the ocean and atmosphere couple Hadley Circulation and Atlantic Overturning circulation, modulating the location and intensity of the ITCZ and the amount of precipitation in monsoon regions. In the extra-tropics, Rossby waves affect the distribution of precipitation and eddy activity, shaping the meridional heat transport from the low latitudes towards the Poles through intermittent events of persistent and co-located blockings and the occurrence of extreme heat waves or cold outbreaks. In the ocean, understanding of energy transfers from large-scale circulation to the internal wave field, through mesoscale and submesoscale eddies, is the basis for the development of new parameterizations and significant modelling advances.
We invite submissions addressing the interplay between Earth’s energy exchanges and the general circulation using modeling, theory, and observations. We encourage contributions on the forced response and natural variability of the general circulation, understanding present-day climate and past and future changes, and impacts of global features and change on regional climate.

Arctic sea ice and high latitude atmosphere and oceans have experienced significant changes over the modern observational era. The polar climate is crucial for the Earth’s energy and water budget, and its variability and change have direct socio-economic and ecological impacts. Thus, understanding high-latitude variability and improving predictions of high latitude climate is highly important for society. Long-term variability in ocean and sea ice are the largest sources for predictability in high latitudes. Dynamical model predictions are not yet in the position to provide us with highly accurate predictions of the polar climate. Main reasons for this are the lack of observations in high latitudes, insufficient initialization methods and shortcomings of climate models in representing some of the important climate processes in high latitudes.
This session aims for a better understanding and better representation of the mechanisms that control high latitude variability and predictability of climate in both hemispheres from sub-seasonal to multi-decadal time-scales in past, recent and future climates. Further, the session aims to discuss ongoing efforts to improve climate predictions at high latitudes at various time scales (e.g., usage of additional observations for initialization, improved initialization methods, impact of higher resolution, improved parameterizations, novel verification approaches) and potential teleconnections of high latitude climate with lower latitude climate. We also aim to link polar climate variability and predictions to potential ecological and socio-economic impacts and encourage submissions on this topic.
The session offers the possibility to present results from ongoing projects and research efforts on the topic of high-latitude climate variability and prediction, including, but not limited to, the WMO Year of Polar Prediction (YOPP), NordForsk-project ARCPATH, MOSAiC, and the H2020-projects APPLICATE, INTAROS, BlueAction, and KEPLER.
This session has greatly benefited by the expansion via added contributions from the CL4.11 session on "Arctic climate change: governing mechanisms and global implications" that specifically aims to identify, characterize and quantify the processes and feedbacks that govern amplified Arctic warming and sea ice retreat, and it also addresses the climate impacts on the lower latitudes associated with Arctic changes.

The Arctic Realm is changing rapidly and the fate of the cryosphere, including Arctic sea ice, glaciers and ice caps, is a source of concern. Whereas sea ice variations impact the radiative energy budget, thus playing a role in Arctic amplification, the Greenland Ice Sheet retreat contributes to global sea level rise. Moreover, through various processes linking the atmosphere, ice and ocean, the change in the Arctic realm may modify the atmospheric and ocean circulation at regional to global scales, the freshwater budget of the ocean and deep-water formation as well as the marine and terrestrial ecosystems, including productivity. The processes and feedbacks involved operate on all time scales and it require a range of types of information to understand the processes, drivers and feedbacks involved in Arctic changes, as well as the land-ocean-cryosphere interaction. In this session, we invite contributions from a range of disciplines and across time scales, including observational (satellite and instrumental) data, historical data, geological archives and proxy data, model simulations and forecasts, for the past, present and future climate. The common denominator of these studies will be their focus on a better understanding of mechanisms and feedbacks on short to long time scales that drive Arctic and subarctic changes and their impact on climate, ocean and environmental conditions, at regional to global scales, including possible links to weather and climate outside the Arctic.

The subtropics present unique regional hydroclimates across the globe, with strong influence from both tropical and mid-latitude dynamics and an extensive interplay between atmospheric thermodynamics, dynamics, and coupled ocean processes. With dependence on both tropical and extratropical processes, subtropical regions are emerging as hotspots of contemporary climate change. These hotspots reflect the paleoclimatological records of high climate sensitivity in subtropical climes (e.g. Green Sahara and Arabia, pluvials in the drylands of southern Africa, Australia). The complexity of subtropical climates present fundamental challenges to develop coherent theories of subtropical climate dynamics, resulting in large uncertainties in climate model simulations. To address these gaps in the understanding of the subtropical climate, we invite contributions focused on subtropical processes and their simulation including:
• diagonal convergence zones
• tropical-extratropical interactions
• subtropical jet fluctuations
• interplays between monsoons and mid-latitude transients
• weather and climate extremes in the subtropics
• analyses of climate simulations looking into past, present and future change in the subtropics
• development of bespoke climate services based on advances in subtropical theory and prediction

Mountain glaciations have a long research heritage since they provide an invaluable record for past and present climate change. However, complex glaciological conditions, geomorphological processes and topography can make regional and intra-hemispheric correlations challenging. This problem is further enhanced by ongoing specialisation within the scientific community, whereby working groups often focus on individual aspects or selected mountain regions, thus frequently remain disconnected.
The main incentive for this session is to evaluate the potential of mountain glaciation records and stimulate further discussion to work towards bridging between specialised research communities. Contributions on all relevant aspects are welcomed, including (but not limited to): (a) glacial landforms and glacier reconstructions, (b) dating techniques and glacier chronologies, (c) glaciology and palaeoclimatic interpretations, (d) impacts on ecosystems and human society.
A special regional focus within the session will be dedicated to the Andean Cordillera and topics such as glaciers and palaeoclimatic records from the Andean Cordillera or model-data comparisons that aim to improve projections of future climate and ice-mass behaviour in the Andes and beyond.
Submissions involving interdisciplinary studies, complex interactions or highlighting the specific conditions of mountain glaciations, from continental to maritime regions at any latitude, are encouraged. The potential of related studies should be highlighted alongside strategies to tackle existing challenges as this will enable the session to fully address the diversity of the topic.
In past years, precursors of this session have steadily become a popular platform for everyone interested in the emerging collaborative research network, “The Legacy of Mountain Glaciations”. This network continues to grow, and we hope the 2022 session will provide an opportunity to meet and exchange new ideas and expertise.
The interactions between aerosols, climate, and weather are among the large uncertainties of current atmospheric research. Mineral dust is an important natural source of aerosol with significant implications on radiation, cloud microphysics, atmospheric chemistry and the carbon cycle via the fertilization of marine and terrestrial ecosystems. In addition, properties of dust deposited in sediments and ice cores are important (paleo-)climate indicators.
This interdivisional session --building bridges between the EGU divisions CL, AS, SSP, BG and GM-- had its first edition in 2004 and it is open to contributions dealing with:
(1) measurements of all aspects of the dust cycle (emission, transport, deposition, size distribution, particle characteristics) with in situ and remote sensing techniques,
(2) numerical simulations of dust on global, regional, and local scales,
(3) meteorological conditions for dust storms, dust transport and deposition,
(4) interactions of dust with clouds and radiation,
(5) influence of dust on atmospheric chemistry,
(6) fertilization of ecosystems through dust deposition,
(7) any study using dust as a (paleo-)climate indicator, including sediment archives in loess, ice cores, lake sediments, ocean sediments and dunes.
We especially encourage the submission of papers that integrate different disciplines and/or address the modelling of past, present and future climates.

The Earth's climate is highly variable on all spatial and temporal scales, and this has direct consequences for society. For example, changes in variability (spatial or temporal) can impact the recurrence frequency of extreme events. Yet it is unclear if a warmer future is one with more or with less climate variability, and at which scales, as a multitude of feedbacks is involved and the instrumental record is short.
The session is multidisciplinary and brings together people working in the geosciences, atmospheric science, oceanography, glaciology, paleoclimatology and environmental physics, to examine the complementarity of ideas and approaches. Members of the PAGES working group on Climate Variability Across Scales (CVAS) and others are welcome.
This session also aims to nurture the development of fractals, multifractals and related nonlinear methodologies applicable to a wide range of geophysical systems and their multiscale interactions. Theories considering scalar and vector fields, applications ranging from urban geosciences (e.g., land use patterns, water management, ecosystems) to atmospheric and oceanic turbulence (e.g., wind energy, mesoscale scaling anisotropy) and climate (e.g., multiscale evolution of extremes), analysis of in-situ, remotely sensed and simulated data are of interest.
Our aim is to provide a forum to present work on:
1- the characterization of climate dynamics using a variety of techniques (e.g. scaling and multifractal techniques and models, recurrence plots, or variance analyses) to study its variability including periodicities, noise levels, or intermittency)
2- the relationship between changes in the mean state (e.g. glacial to interglacial or preindustrial to present to future), and higher-order moments of relevant climate variables, to changes in extreme-event occurrence and the predictability of climate
3- the role of ocean, atmosphere, cryosphere, and land-surface processes in fostering long-term climate variability through linear – or nonlinear – feedbacks and mechanisms
4- the attribution of climate variability to internal dynamics, or the response to natural (volcanic or solar) and anthropogenic forcing
5- the interaction of external forcing (e.g. orbital forcing) and internal variability such as mechanisms for synchronization and pacing of glacial cycles
6- the characterization of probabilities of extremes, including linkage between slow climate variability and extreme event recurrence
The North Atlantic exhibits a high level of natural variability from interannual to centennial time scales, making it difficult to extract trends from observational time series. Climate models, however, predict major changes in this region, which in turn will influence sea level and climate, especially in western Europe and North America. In the last years, several observational projects have been focused on the Atlantic circulation changes, for instance ACSIS, RACE, RAPID, OSNAP, and OVIDE. Another important issue is the interaction between the atmosphere and the ocean as well as the cryosphere with the ocean, and how this affects the climate.
We welcome contributions from observers and modelers on the following topics:
-- climate relevant processes in the North Atlantic region in the atmosphere, ocean, and cryosphere
-- response of the atmosphere to changes in the North Atlantic
-- atmosphere - ocean coupling in the North Atlantic realm on time scales from years to centuries (observations, theory and coupled GCMs)
-- interpretation of observed variability in the atmosphere and the ocean in the North Atlantic sector
-- comparison of observed and simulated climate variability in the North Atlantic sector and Europe
-- dynamics of the Atlantic meridional overturning circulation
-- variability in the ocean and the atmosphere in the North Atlantic sector on a broad range of time scales
-- changes in adjacent seas related to changes in the North Atlantic
-- role of water mass transformation and circulation changes on anthropogenic carbon and other parameters
-- linkage between the observational records and proxies from the recent past

The interaction between the ocean and the cryosphere in the Southern Ocean has become a major focus in climate research. Antarctic climate change has captured public attention, which has spawned a number of research questions, such as: Is Antarctic sea ice becoming more vulnerable in a changing climate? Where and when will melting of ice shelves by warm ocean waters yield a tipping point in Antarctic climate? What role do ice-related processes play in nutrient upwelling on the continental shelf and in triggering carbon export to deep waters? Recent advances in observational technology, data coverage, and modeling provide scientists with a better understanding of the mechanisms involving ice-ocean interactions in the far South. Processes on the Antarctic continental shelf have been identified as missing links between the cryosphere, the global atmosphere and the deep open ocean that need to be captured in large-scale and global model simulations.
This session calls for studies on physical and biogeochemical interactions between ice shelves, sea ice and the ocean. The ice-covered Southern Ocean and its role in the greater Antarctic climate system are of major interest. This includes work on all scales, from local to basin-scale to circumpolar. Studies based on in-situ observations and remote sensing as well as regional to global models are welcome. We particularly invite cross-disciplinary topics involving physical and biological oceanography, glaciology or biogeochemistry.

Ocean ventilation is a process by which water properties imprinted by the atmosphere onto the upper ocean, such as oxygen, carbon dioxide and trace gases, are transported into the ocean interior. In mediating the exchange between the atmosphere and the ocean, ventilation plays an important role in both climate variability and biogeochemical cycles. This is manifested, for example, through the supply of oxygen to the ocean interior, transport and sequestration of nutrients, and the uptake and storage of anthropogenic carbon and heat in the ocean interior. Increased stratification - caused by the warming on the upper ocean under climate change - could lead to a reduction of ocean ventilation over the coming decades. However, the mechanism by which the changes in ocean ventilation will emerge, and their consequences for climate feedback, biogeochemical processes, and ocean ecosystems are not well known.
Developing our understanding of ocean ventilation is inhibited by the wide range of spatial scales inherent in the process, from small-scale mixing to basin scale. Robust projection of future change requires deeper insight into the processes driving ventilation, the spatial and temporal variability of ventilation, and the consequences and impacts of ventilation changes.
We invite contributions that advance understanding on the broad topic of ocean ventilation, its potential to change in a warming climate, and the consequences therein. We seek contributions that investigate both the physical processes involved in ocean ventilation — from small-scale mixing, to mesoscale stirring, to basin scale subduction — as well as the consequences for biogeochemical cycles and marine ecosystems. We welcome contributions from process-oriented studies as well as those that assess and quantify variability and projected changes, and welcome studies making use of observations, theory and/or numerical model.
The session is expected to be in a hybrid format, partly taking place in Vienna in a traditional format, and partly online.
The rapid decline of the Arctic sea ice in the last decade is a dramatic indicator of climate change. The Arctic sea ice cover is now thinner, weaker and drifts faster. Freak heatwaves are common. On land, the permafrost is dramatically thawing, glaciers are disappearing, and forest fires are raging. The ocean is also changing: the volume of freshwater stored in the Arctic has increased as have the inputs of coastal runoff from Siberia and Greenland and the exchanges with the Atlantic and Pacific Oceans. As the global surface temperature rises, the Arctic Ocean is speculated to become seasonally ice-free by the mid 21st century, which prompts us to revisit our perceptions of the Arctic system as a whole. What could the Arctic Ocean look like in the future? How are the present changes in the Arctic going to affect and be affected by the lower latitudes? What aspects of the changing Arctic should observational, remote sensing and modelling programmes address in priority?
In this session, we invite contributions from a variety of studies on the recent past, present and future Arctic. We encourage submissions examining interactions between the ocean, atmosphere and sea ice, on emerging mechanisms and feedbacks in the Arctic and on how the Arctic influences the global ocean. Submissions taking a cross-disciplinary, system approach and focussing on emerging cryospheric, oceanic and biogeochemical processes and their links with land are particularly welcome.
The session supports the actions of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030) towards addressing challenges for sustainable development in the Arctic and its diverse regions. We aim to promote discussions on the future plans for Arctic Ocean modelling and measurement strategies, and encourages submissions on the results from IPCC CMIP and the recent observational programs, such as the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC). This session is cosponsored by the CLIVAR /CliC Northern Ocean Regional Panel (NORP) that aims to facilitate progress and identify scientific opportunities in (sub)Arctic ocean-sea-ice-atmosphere research.
Drs Karen Assmann and Wilken-Jon von Appen are the solicited speakers for the session. Karen Assmann will be presenting on physical and ecological implications of Arctic Atlantification. Wilken-Jon von Appen will be talking about eddies in the Arctic Ocean.

The dynamics of the Earth system and its components is highly nonlinear. In particular, several subsystems have been suggested to react abruptly at critical levels of anthropogenic forcing. Well-known examples of such Tipping Elements include the Atlantic Meridional Overturning Circulation, the polar ice sheets and sea ice, tropical and boreal forests, as well as the Asian monsoon systems. Interactions between the different Tipping Elements may either have stabilizing or destabilizing effects on the other subsystems, potentially leading to cascades of abrupt transitions. The critical forcing levels at which abrupt transitions occur have recently been associated with Tipping Points.
It is paramount to determine the critical forcing levels (and the associated uncertainties) beyond which the systems in question will abruptly change their state, with potentially devastating climatic, ecological, and societal impacts. For this purpose, we need to substantially enhance our understanding of the dynamics of the Tipping Elements and their interactions, on the basis of paleoclimatic evidence, present-day observations, and models spanning the entire hierarchy of complexity. Moreover, to be able to mitigate - or prepare for - potential future transitions, early warning signals have to be identified and monitored in both observations and models.
This multidisciplinary session invites contributions that address Tipping Points in the Earth system from the different perspectives of all relevant disciplines, including
- the mathematical theory of abrupt transitions in (random) dynamical systems,
- paleoclimatic studies of past abrupt transitions,
- data-driven and process-based modelling of past and future transitions,
- early-warning signals
- the implications of abrupt transitions for Climate sensitivity and response,
- ecological and societal impacts, as well as
- decision theory in the presence of uncertain Tipping Point estimates

Climate services challenge the traditional interface between users and providers of climate information as it requires the establishment of a dialogue between subjects, who often have limited knowledge of each-other’s activities and practices. Increasing the understanding and usability of climate information for societal use has become a major challenge where economic growth, and social development crucially depends on adaptation to climate variability and change.
To this regard, climate services do not only create user-relevant climate information, but also stimulate the need to quantify vulnerabilities and come up with appropriate adaptation solutions that can be applied in practice.
The operational generation, management and delivery of climate services poses a number of new challenges to the traditional way of accessing and distributing climate data. With a growing private sector playing the role of service provider is important to understand what are the roles and the responsibilities of the publicly funded provision of climate data and information and services.
This session aims to gather best practices and lessons learnt, for how climate services can successfully facilitate adaptation to climate variability and change by providing climate information that is tailored to the real user need.
Contributions are strongly encouraged from international efforts (GFCS, CSP, ClimatEurope…); European Initiatives (H2020, ERA4CS, C3S, JPI-Climate…) as well as national, regional and local experiences.
Modelling the Earth system with state-of-the-art Earth System models is computationally expensive. Therefore, emulators, also known as simple or reduced complexity climate models, are useful as they are able to produce individual climate projections with reduced computational resources. They play a key role in the climate assessments of the IPCC’s Working Group 1 and Working Group 3 reports. Emulators also play a role in coupling climate models to Integrated Assessment models and exploring potential effects of missing feedbacks in the development of socioeconomic and emissions scenarios.
The lower computational burden of emulators allows for a multitude of possibilities. Large probabilistic model ensembles can represent uncertainty in climate projections that is difficult to quantify in a full-complexity ESM, usually through the variation in a number of parameters that can be tuned to alter the emulator behaviour. Emulators may have physical, statistical, or machine learning elements, and can range in complexity from spreadsheet-based projections of global-mean temperature from prescribed radiative forcing through to simplified variants of operational ESMs.
We invite presentations on all aspects of the development and application of simple climate and geophysical models, including but not limited to:
1. the development of emulators, results, and case studies
2. the role of emulators in integrated assessment and scenario generation
3. best practices in tuning and calibration of emulators to observations and full-complexity Earth System models
4. Use of emulators to better understand complex model differences and behaviours
5. Strategies for emulating internal variability, teleconnections, regional climate, climate extremes, tipping points and missing processes in Earth System models (e.g. permafrost)
6. models that focus on one particular complex aspect of the Earth system (for example land and ocean carbon cycles, aerosol-climate interactions or the cryosphere)

Public information:
This session explores the utility of simple climate and geophysical models for process-based and global-level understanding. Simplified models use physical or statistical methods to emulate processes in the Earth system at higher computational efficiency, allowing for uncertainty analysis with large ensembles. In many cases, emulators have lower code overheads and a tractable number of equations, lowering the barrier to entry for Earth System modelling.

Over recent decades we have gained a robust understanding of climate change fundamentals, but its specific and localized impacts are anything but certain. The need to provide boundary conditions for forecasting and computational modelling has increased the importance of quantitative methods in the field of palaeoenvironmental, palaeoclimatic, palaeohydrological and palaeofire reconstruction.
Continental environmental archives (e.g. speleothems, lake and river sediments, peatlands, and vertebrate and invertebrate remains) are often highly temporally resolved (subdecadal to seasonal) and provide more direct information about atmospheric and hydrological processes than marine archives. The wide variety of continental archives allows for intercomparison and ground-truthing of results from different environments, while multi-proxy reconstructions from the same archive can disentangle local and supra-regional environmental conditions. This approach is particularly useful when dealing with high spatial variability, signal buffering, nonlinearities, and uncertainties in the proxy sensitivity.
This session aims to highlight recent advances in the use of innovative and quantitative proxies to reconstruct past environmental change on land. We welcome studies of all continental archives, including but not limited to carbonates (caves, palaeosols, snails), sediments (lakes, peatlands, rivers, alluvial fans), and biological materials (tree rings, fossil assemblages, bones, biomarkers). We particularly encourage studies involving the calibration of physical and chemical proxies that incorporate modern transfer functions, forward modeling and/or geochemical modeling to predict proxy signals, and quantitative estimates of past temperature and palaeohydrological dynamics. We also invite reconstructions of temperature and hydrologic variability over large spatial scales and palaeoclimate data assimilation. This session provides a forum for discussing recent innovations and future directions in the development of continental palaeoenvironmental proxies on seasonal to multi-millennial timescales.

The Quaternary Period (last 2.6 million years) is characterized by frequent and abrupt climate swings that were accompanied by rapid environmental change. Studying these changes requires accurate and precise dating methods that can be effectively applied to environmental archives. A range of different methods or a combination of various dating techniques can be used, depending on the archive, time range, and research question. Varve counting and dendrochronology allow for the construction of high-resolution chronologies, whereas radiometric methods (radiocarbon, cosmogenic in-situ, U-Th) and luminescence dating provide independent anchors for chronologies that span over longer timescales. We particularly welcome contributions that aim to (1) reduce, quantify and express dating uncertainties in any dating method, including high-resolution radiocarbon approaches; (2) use established geochronological methods to answer new questions; (3) use new methods to address longstanding issues, or; (4) combine different chronometric techniques for improved results, including the analysis of chronological datasets with novel methods, e.g. Bayesian age-depth modeling. Applications may aim to understand long-term landscape evolution, quantify rates of geomorphological processes, or provide chronologies for records of climate change.

Downscaling aims to process and refine global climate model output to provide information at spatial and temporal scales suitable for impact studies. In response to the current challenges posed by climate change and variability, downscaling techniques continue to play an important role in the development of user-driven climate information and new climate services and products. In fact, the "user's dilemma" is no longer that there is a lack of downscaled data, but rather how to select amongst the available datasets and to assess their credibility. In this context, model evaluation and verification is growing in relevance and advances in the field will likely require close collaboration between various disciplines.
Furthermore, epistemologists have started to revisit current practices of climate model validation. This new thread of discussion encourages to clarify the issue of added value of downscaling, i.e. the value gained through adding another level of complexity to the uncertainty cascade. For example, the ‘adequacy-for-purpose view’ may offer a more holistic approach to the evaluation of downscaling models (and atmospheric models, in general) as it considers, for example, user perspectives next to a model’s representational accuracy.
In our session, we aim to bring together scientists from the various geoscientific disciplines interrelated through downscaling: atmospheric modeling, climate change impact modeling, machine learning and verification research. We also invite philosophers of climate science to enrich our discussion about novel challenges faced by the evaluation of increasingly complex simulation models.
Contributions to this session may address, but are not limited to:
- newly available downscaling products,
- applications relying on downscaled data,
- downscaling method development, including the potential for machine learning,
- bias correction and statistical postprocessing,
- challenges in the data management of kilometer-scale simulations,
- verification, uncertainty quantification and the added value of downscaling,
- downscaling approaches in light of computational epistemology.

Numerical frameworks are essential for understanding and interpreting landscape evolution. Over recent decades, geochronological techniques such as cosmogenic nuclides, thermochronology, radiocarbon and luminescence dating have improved in accuracy, precision, and temporal range. Developments in geochronological methods, data treatment and landscape evolution models have provided new insights into the timing, duration and intensity of landscape evolution processes. The combination of temporal constraints with numerical modelling has enormous potential for improving our understanding of landscape evolution. The focus of this session is to bring together geochronology, data science and models of Quaternary landscape change.
This session includes studies of erosional rates and processes, sediment provenance, burial and transport times, bedrock exposure or cooling histories, landscape dynamics, and the examination of potential biases and discordances in geochronological data and model-data comparisons. We welcome contributions that apply and combine novel geochronological methods and that intersect different geochronological techniques and numerical modelling with landscape evolution analysis. This includes the determination of rates and timing of landscape change as well as stochastic events, or that highlight the latest developments and open questions in the application of geochronometers to landscape evolution problems.

This session invites contributions on the latest developments and results in lidar remote sensing of the atmosphere, covering • new lidar techniques as well as applications of lidar data for model verification and assimilation, • ground-based, airborne, and space-borne lidar systems, • unique research systems as well as networks of instruments, • lidar observations of aerosols and clouds, thermodynamic parameters and wind, and trace-gases. Atmospheric lidar technologies have shown significant progress in recent years. While, some years ago, there were only a few research systems, mostly quite complex and difficult to operate on a longer-term basis because a team of experts was continuously required for their operation, advancements in laser transmitter and receiver technologies have resulted in much more rugged systems nowadays, many of which are already operated routinely in networks and some even being automated and commercially available. Consequently, also more and more data sets with very high resolution in range and time are becoming available for atmospheric science, which makes it attractive to consider lidar data not only for case studies but also for extended model comparison statistics and data assimilation. Here, ceilometers provide not only information on the cloud bottom height but also profiles of aerosol and cloud backscatter signals. Scanning Doppler lidars extend the data to horizontal and vertical wind profiles. Raman lidars and high-spectral resolution lidars provide more details than ceilometers and measure particle extinction and backscatter coefficients at multiple wavelengths. Other Raman lidars measure water vapor mixing ratio and temperature profiles. Differential absorption lidars give profiles of absolute humidity or other trace gases (like ozone, NOx, SO2, CO2, methane etc.). Depolarization lidars provide information on the shapes of aerosol and cloud particles. In addition to instruments on the ground, lidars are operated from airborne platforms in different altitudes. Even the first space-borne missions are now in orbit while more are currently in preparation. All these aspects of lidar remote sensing in the atmosphere will be part of this session.

Continues monitoring of infrastructure systems are essential to ensure a reliable movement of people and goods, which involves in the economy growth and human interaction. The wide variety of instruments available allows diverse applications to increase data availability for a better understanding of geotechnical surroundings which are directly linked to the safe operation of infrastructures to prevent catastrophise such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding and even wildfires close to the highways. Understanding mentioned events are vital to provide a safe infrastructure in extreme climate conditions. This session focus on the application of geosciences and geophysical instrumentation including sensors on the infrastructures monitoring and data analysis from critical infrastructures (e.g., roadways, railway system, bridges, tunnels, water supply, underground utilities, electrical grids, and other embedded facilities in cities). The session aims to increase knowledge on geo-infrastructure management to overcome future challenges associated with the societal and human interaction, present advance knowledge research and novel approaches from various disciplines with a vibrant interaction to economy and human-interaction studies to provide an efficient infrastructure management system. The session is considered inter-and transdisciplinary (ITS) session. The applications and topics include but are not limited to: (1) Advance knowledge of the destructive and non-destructive geoscience and geophysical techniques including contactless and non-contactless techniques such as sensors. (2) Intelligent data analysis approaches to analyse accurate and precise interpretation of big data sets driven from various technologies (e.g., computer vision and image, and signal processing). (3) Influence of the surrounding areas on infrastructure management systems linked to natural events such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding, wildfires and extreme weather condition. (4) Continuous real-time monitoring to provide smart tools such as an integration of geosciences data with BIM models, Internet of Things, digital twins, robotic monitoring, artificial intelligence, automation systems based on machine learning and computational modelling for better decision-making for infrastructure owner/operators. (5) Human-interaction computer-based aided to generate reliable infrastructures.
Machine learning, artificial intelligence and big data approaches have recently emerged as key tools in understanding the cryosphere. These approaches are being increasingly applied to answer long standing questions in cryospheric science, including those relating to remote sensing, forecasting, and improving process understanding across Antarctic, Arctic and Alpine regions. In doing so, data science and AI techniques are being used to gain insight into system complexity, analyse data on unprecedented temporal and spatial scales, and explore much wider parameter spaces than were previously possible.
In this session we invite submissions that utilise data science and/or AI techniques that address research questions relating to glaciology, sea ice, permafrost and/or polar climate science. Approaches used may include (but are not limited to) machine learning, artificial intelligence, big data processing/automation techniques, advanced statistics, and innovative software/computing solutions. These could be applied to any (or combinations) of data sources including remote sensing, numerical model output and field/lab observations. We particularly invite contributions that apply techniques and approaches that reveal new insights into cryospheric research problems that would not otherwise be achievable using traditional methods, and those that discuss how or if approaches can be applied or adapted to other areas of cryospheric science. Given the rapid development of this field by a diverse group of international researchers, we convene this session to help foster future collaboration amongst session contributors, attendees, and international stakeholders and help address the most challenging questions in cryospheric science.

Scientific drilling through the International Ocean Discovery Program (IODP) and the International Continental Scientific Drilling Program (ICDP) continues to provide unique opportunities to investigate the workings of the interior of our planet, Earth’s cycles, natural hazards and the distribution of subsurface microbial life. The past and current scientific drilling programs have brought major advances in many multidisciplinary fields of socio-economic relevance, such as climate and ecosystem evolution, palaeoceanography, the deep biosphere, deep crustal and tectonic processes, geodynamics and geohazards. This session invites contributions that present and/or review recent scientific results from deep Earth sampling and monitoring through ocean and continental drilling projects. Furthermore, we encourage contributions that outline perspectives and visions for future drilling projects, in particular projects using a multi-platform approach.

This session invites innovative Earth system and climate studies based on geodetic measuring techniques. Modern geodetic observing systems document a wide range of changes in the Earth’s solid and fluid layers at very diverging spatial and temporal scales related to processes as, e.g., glacial isostatic adjustment, the terrestrial water cycle, ocean dynamics and ice-mass balance. Different time spans of observations need to be cross-compared and combined to resolve a wide spectrum of climate-related signals. Geodetic observables are also often compared with geophysical models, which helps to explain observations, evaluate simulations, and finally merge measurements and numerical models via data assimilation.
We appreciate contributions utilizing geodetic data from diverse geodetic satellites including altimetry, gravimetry (CHAMP, GRACE, GOCE and GRACE-FO), navigation satellite systems (GNSS and DORIS) or remote sensing techniques that are based on both passive (i.e., optical and hyperspectral) and active (i.e., SAR) instruments. We welcome studies that cover a wide variety of applications of geodetic measurements and their combination to observe and model Earth system signals in hydrological, ocean, atmospheric, climate and cryospheric sciences. Any new approaches helping to separate and interpret the variety of geophysical signals are equally appreciated. Contributions working towards any of the goals of the Inter-Commission Committee on "Geodesy for Climate Research" (ICCC) of the International Association of Geodesy (IAG) are also welcomed in this session.
With author consent, highlights from this session will be tweeted with a dedicated hashtag during the conference in order to increase the impact of the session.

This interdisciplinary session brings together modellers and observationalists to present results and exchange knowledge and experience in the use of inverse methods, geostatistics and data assimilation - including machine learning - in cryospheric science.
In numerous research fields it is now possible not only to deduce static features of a physical system but also to retrieve information on transient processes between different states or even regime shifts. In the cryospheric sciences a large potential for future developments lies at the intersection of observations and models with the aim to yield prognostic capabilities in space and time. Compared to other geoscientific disciplines like meteorology or oceanography, where techniques such as data assimilation have been well established for decades, in cryospheric sciences only the foundation has been laid for the use of these techniques, one reason often being the sparsity of observations.
We invite contributions from a wide range of methodologies - from satellite observations to deep-looking geophysical methods and advancements in numerical techniques, and from topics including permafrost, sea ice and snow to glaciers and ice sheets, covering static system characterisations as well as transient processes.

The largest single source of uncertainty in projections of future global sea level is associated with the mass balance of the Antarctic Ice Sheet (AIS). In the short-term, it cannot be stated with certainty whether the mass balance of the AIS is positive or negative; in the long-term, the possibility exists that melting of the coastal shelves around Antarctica will lead to an irreversible commitment to ongoing sea level rise. Observational and paleoclimate studies can help to reduce this uncertainty, constraining the parameterizations of physical processes within ice sheet models and allowing for improved projections of future global sea level rise. This session welcomes presentations covering all aspects of observation, paleoclimate reconstruction and modeling of the AIS. Presentations that focus on the mass balance of the AIS and its contribution towards changes in global sea level are particularly encouraged.
Long term observations are of vital importance in the Earth Sciences, yet often difficult to pursue and fund. The distinction of a fluctuation from a long-term change in Earth processes is a key question to better understand processes within the Earth and in the Earth system. Likewise, it is a prerequisite for the assessment of the Earth's climate change as well as risk assessment. In order to distinguish fluctuations from a steady change, knowledge on the time variability of the signal itself and long term observations are required. Exemplarily, due to the decadal variability of sea level, reliable sea level trends can only be obtained after about sixty years of continuous observations. Reliable strain rates of deformation require a minimum of a decade of continuous data, due to ambient and anthropogenic factors leading to fluctuations. This session invites contributions demonstrating the importance of long term geophysical, geodynamic, oceanographic, geodetic, and climate observatories. Advances in sensors, instrumentation, monitoring techniques, analyses, and interpretations of data, or the comparison of approaches are welcome, with the aim to stimulate a multidisciplinary discussion among those dedicated to the accumulation, preservation and dissemination of data over decadal time scales or beyond. Studies utilizing novel approaches such as AI for analysis of long time series are very welcome. Likewise, studies that show the mutual transfer of knowledge of terrestrial and satellite observations are a topic of interest. With this session, we also would like to provide an opportunity to gather and exchange experiences for representatives from observatories both in Europe and worldwide.
The MacGyver session focuses on novel sensors made, or data sources unlocked, by scientists. All geoscientists are invited to present:
- new sensor systems, using technologies in novel or unintended ways,
- new data storage or transmission solutions sending data from the field with LoRa, WIFI, GSM, or any other nifty approach,
- started initiatives (e.g., Open-Sensing.org) that facilitate the creation and sharing of novel sensors, data acquisition and transmission systems.
Connected a sensor to an Arduino or Raspberri Pi? Used the new Lidar in the new iPhone to measure something relevant for hydrology? 3D printed an automated water quality sampler? Or build a Cloud Storage system from Open Source Components? Show it!
New methods in hydrology, plant physiology, seismology, remote sensing, ecology, etc. are all welcome. Bring prototypes and demonstrations to make this the most exciting Poster Only (!) session of the General Assembly.

Glacial Isostatic Adjustment (GIA) describes the dynamic response of the solid Earth to ice sheet glaciation/deglaciation, which affects the spatial and temporal sea level changes, and induces surface deformation, gravitational field variation and stress changes in the subsurface. The process is influenced by the ice sheet characteristics (e.g., extent, volume, grounding line) and solid Earth structure. With more observational data (e.g., relative sea-level data, GPS data, tide gauges, terrestrial and satellite gravimetry, glacially induced faults) are available/standardized, we can better investigate the interactions between the ice sheets, solid Earth and sea levels, and reveal the ice sheet and sea-level evolution histories and rheological properties of the Earth.
This session invites contributions discussing observations, analysis, and modelling of ice sheet dynamics, solid Earth response, and the resulting global, regional and local sea-level changes and land deformation, including paleo ice sheet and paleo sea-level investigations, geodetic measurements of crustal motion and gravitational change, GIA modelling with complex Earth models (e.g., 3D viscosity, non-linear rheologies) and coupled ice-sheet/Earth modelling, investigations on glacially triggered faulting as well as the Earth’s elastic response to present-day ice mass changes. We also welcome abstracts that address the future ice sheets/shelves evolution and sea-level projection as well as GIA effects on oil migration and nuclear waste repositories. Contributions related to both polar regions and previously glaciated regions are welcomed. This session is co-sponsored by the SCAR sub-committee INSTANT-EIS, Earth - Ice - Sea level, in view of instabilities and thresholds in Antarctica https://www.scar.org/science/instant/home/.
Soils and palaeosols develop under the influence of various environmental factors that produce specific soil features, thus keeping a memory of both current and past environments. They are valuable archives of human activities that shaped environments and affected soil formation over the Holocene period. They can be studied to reconstruct environmental factors that were present during the time of their formation, and to disentangle the relative influences of different environmental conditions, both local and regional, on soil formation. Despite the increasing consideration of palaeosols in sedimentary successions, studies linking pedogenesis and sedimentary processes are still underrepresented. Anthropogenic soils in archaeological settings provide valuable archives for geoarchaeological studies, with their stratigraphy and properties reflecting settlement life cycles (occupation, abandonment, and reoccupation) and land-use history. Land-use legacy soils also have enormous potential for process-related research such as studying the long-term effects on the organic and inorganic carbon budget, physical compaction, aggregation, formation of anthropogenic pedofeatures and more.
This session is open for all contributions focused on the study of palaeosols, anthropogenic soils, and anthropogenically-affected soils, in particular on:
- The use of palaeosols and land-use legacy soils as records of present and former environments, both local and regional;
- Palaeosols and anthropogenically-affected soils and their relationships with sedimentary processes;
- Anthropogenic soils and palaeosols in archaeological contexts;
- The methodological progress in the study of soil records (for example, advances in biochemical, geochemical, and micromorphological (sub-)microscopic techniques in palaeopedology, in the interpretation of palaeoenvironmental data such as biomarker and isotope data, in remote sensing or modelling methods used to map and analyze spatial patterns of palaeosol and land use legacy soil distribution);
- Predictions of future soil changes as a result of changes in environmental conditions and/or land-use, based on observed past soil responses to environmental changes.

Tsunamis and storm surges pose significant hazards to coastal communities around the world. Geological investigations, including both field studies and modelling approaches, significantly enhance our understanding of these events. Past extreme wave events may be reconstructed based on sedimentary and geomorphological evidence from low and high energy environments, from low and high latitude regions and from coastal and offshore areas. The development of novel approaches to identifying, characterising and dating evidence for these events supplements a range of established methods. Nevertheless, the differentiation between evidence for tsunamis and storms still remains a significant question for the community. Numerical and experimental modelling studies complement and enhance field observations and are crucial to improving deterministic and probabilistic approaches to hazard assessment. This session welcomes contributions on all aspects of paleo-tsunami and paleo-storm surge research, including studies that use established methods or recent interdisciplinary advances to reconstruct records of past events, or forecast the probability of future events.
Modelling past climate states, and the transient evolution of Earth’s climate remains challenging. Time periods such as the Paleocene, Eocene, Pliocene, the Last Interglacial, the Last Glacial Maximum or the mid-Holocene span across a vast range of climate conditions. At times, these lie far outside the bounds of the historical period that most models are designed and tuned to reproduce. However, our ability to predict future climate conditions and potential pathways to them is dependent on our models' abilities to reproduce just such phenomena. Thus, our climatic and environmental history is ideally suited to thoroughly test and evaluate models against data, so they may be better able to simulate the present and make future climate projections.
We invite papers on palaeoclimate-specific model development, model simulations and model-data comparison studies. Simulations may be targeted to address specific questions or follow specified protocols (as in the Paleoclimate Modelling Intercomparison Project – PMIP or the Deep Time Model Intercomparison Project – DeepMIP). They may include anything between time-slice equilibrium experiments to long transient climate simulations (e.g. transient simulations covering the entire glacial cycle as per the goal of the PalMod project) with timescales of processes ranging from synoptic scales to glacial cycles and beyond. Comparisons may include past, historical as well as future simulations and focus on comparisons of mean states, gradients, circulation or modes of variability using reconstructions of temperature, precipitation, vegetation or tracer species (e.g. δ18O, δD or Pa/Th).
Evaluations of results from the latest phase of PMIP4-CMIP6 are particularly encouraged. However, we also solicit comparisons of different models (comprehensive GCMs, isotope-enabled models, EMICs and/or conceptual models) between different periods, or between models and data, including an analysis of the underlying mechanisms as well as contributions introducing novel model or experimental setups.

One of the big challenges in Earth system science consists in providing reliable climate predictions on sub-seasonal, seasonal, decadal and longer timescales. The resulting data have the potential to be translated into climate information leading to a better assessment of global and regional climate-related risks.
The latest developments and progress in climate forecasting on subseasonal-to-decadal and longer timescales will be discussed and evaluated. This will include presentations and discussions of predictions for the different time horizons from dynamical ensemble and statistical/empirical forecast systems, as well as the aspects required for their application: forecast quality assessment, multi-model combination, bias adjustment, downscaling, exploration of artificial-intelligence methods, etc.
Following the new WCRP strategic plan for 2019-2029, prediction enhancements are solicited from contributions embracing climate forecasting from an Earth system science perspective. This includes the study of coupled processes between atmosphere, land, ocean, and sea-ice components, as well as the impacts of coupling and feedbacks in physical, chemical, biological, and human dimensions. Contributions are also sought on initialization methods that optimally use observations from different Earth system components, on assessing and mitigating the impacts of model errors on skill, and on ensemble methods.
We also encourage contributions on the use of climate predictions for climate impact assessment, demonstrations of end-user value for climate risk applications and climate-change adaptation and the development of early warning systems.
A special focus will be put on the use of operational climate predictions (C3S, NMME, S2S), results from the CMIP5-CMIP6 decadal prediction experiments, and climate-prediction research and application projects.
An increasingly important aspect for climate forecast's applications is the use of most appropriate downscaling methods, based on dynamical or statistical approaches or their combination, that are needed to generate time series and fields with an appropriate spatial or temporal resolution. This is extensively considered in the session, which therefore brings together scientists from all geoscientific disciplines working on the prediction and application problems.

Regional climate modeling has become a fundamental tool to study regional climate change processes and produce regional climate projections. This research area has expanded strongly in the last decades, in particular, with the inception of the Coordinated Regional Climate Downscaling Experiment (CORDEX), the main reference international program within the regional modeling community. Within CORDEX, two new initiatives have been launched, the CORDEX-CORE program and the CORDEX Flagship Pilot Studies (FPS). This session accepts papers on recent developments and application of regional climate models (RCMs), from hydrostatic to convection permitting resolutions; use of RCMs for climate change projection, impact assessment and climate service activities; studies pertaining to the CORDEX, CORDEX-CORE and CORDEX-FPS programs; development and application of fully coupled regional earth system models.

Predictions of climate from seasonal to decadal timescales and their applications are discussed in this session. With a time horizon from a few months up to thirty years, such predictions are of major importance to society, and improving them presents an interesting scientific challenge. This session aims to embrace advances in our understanding of the origins of seasonal to decadal predictability, as well as in improving the respective forecast skill and making the most of this information by developing and evaluating new applications and climate services.
The session covers dynamical as well as statistical predictions (including machine learning methods) and their combination. It investigates predictions of various climate phenomena, including extremes, from global to regional scales, and from seasonal to multi-decadal timescales ("seamless predictions"). Physical processes relevant to long-term predictability sources (e.g. ocean, cryosphere, or land) as well as predicting large-scale atmospheric circulation anomalies associated to teleconnections are discussed, as are observational and emergent constraints on climate variability and predictability. Also, the time-dependence of the predictive skill, or windows of opportunity (hindcast period), are investigated. Analysis of predictions in a multi-model framework, and ensemble forecast initialization and generation, including innovative ensemble approaches to minimize initialization shocks, are another focus of the session. The session pays particular attention to innovative methods of quality assessment and verification of climate predictions, including extreme-weather frequencies, post-processing of climate hindcasts and forecasts, and quantification and interpretation of model uncertainty. We particularly invite contributions presenting the use of seasonal-to-decadal predictions for risk assessment, adaptation and further applications.

Homogeneous long-term data records (i.e., well calibrated quality-controlled data that are forced to look like a common reference) are essential for researching, monitoring, or attenuating changes in climate, for example to describe the state of climate or to detect climate extremes. Likewise, reanalysis requires harmonized data records (i.e., well calibrated quality-controlled data that maintained the unique nature of each sensor). Climate data records need to be screened and cleared from artificial non-climatic temporal and/or spatial effects, such as gradual degradation of instruments, jumps due to instruments changes, jumps due to observation practices changes, or jumps due to changes of station location and exposure. The magnitude and uncertainty of these gradual and/or abrupt changes determines their suitability for climate trend analyses. Therefore, data intended for applications, such as making a realistic and reliable assessment of historical climate trends and variability, require consistently homogenized and/or harmonized data records including measurement uncertainties.
The above described artificial non-climatic effects influence the quality of different Essential Climate Variables (ECVs), including atmospheric (e.g., air temperature, precipitation, wind speed), oceanic (e.g., sea surface temperature), and terrestrial (e.g., albedo, snow cover) variables. Our session calls for contributions, using data records from i) in-situ observing networks, ii) satellite observing systems, and or iii) climate/earth-system model simulations based data records, on the:
• Calibration, quality control, homogenization/harmonization and validation of either Fundamental Climate Data Records (FCDRs) and/or Essential Climate Variables data records (CDRs).
• Development of new data records and their analysis (spatial and temporal characteristics, particularly of extremes).
• Examination of observed trends and variability, as well as studies that explore the applicability of techniques/algorithms to data of different temporal resolutions (annual, seasonal, monthly, daily, and sub-daily).
• Rescue and analysis of centennial meteorological observations, with focus on data prior to the 1960s, as a unique source to fill in the gap of knowledge of climate variability over century time-scales. In particular, we encourage wind studies dealing with the observed slowdown (termed “stilling”; last 30-50 years) and recent recovery (since ~2013) of near-surface winds.

Eco-evolutionary optimality (EEO) theory invokes the power of natural selection to eliminate uncompetitive trait combinations, and thereby shape predictable, general patterns in vegetation structure and composition. Although the implementation of process-based representations derived from EEO principles in vegetation and land-surface models is a relatively recent phenomenon, it is already yielding considerable improvements to our ability to simulate vegetation responses to changing climate and environmental conditions. For example, hypotheses derived from EEO principles are proving helpful in developing parsimonious representations of leaf-level processes such as photosynthesis and primary production, dark respiration, and stomatal behaviour. EEO approaches can also be applied to at whole plant and community levels, providing simple ways of representing plant interactions and ecosystem dynamics. Comparisons of EEO-based predictions against experimental data and field and remote-sensing observations provide a way of evaluating the robustness of the hypotheses, as well as discriminating between alternative EEO hypotheses.
This session is designed to bring together scientists applying EEO approaches to modelling plant behaviour from cellular to community scales, experimentalists and observationalists developing data sets that can be used to evaluate EEO hypotheses, and vegetation and land-surface modellers implementing EEO approaches in existing model frameworks. The session will explore the current state-of-the-art, as well as ways to move EEO-based approaches forward. The key objective is to bring together researchers from different communities working on EEO principles, promoting scientific exchanges that are much needed to develop robust, reliable and realistic next-generation Earth System Models.

High-impact climate and weather events typically result from the interaction of multiple hazards across various spatial and temporal scales. These events, also known as Compound Events, often cause more severe socio-economic impacts than single-hazard events, rendering traditional univariate extreme event analyses and risk assessment techniques insufficient. It is therefore crucial to develop new methodologies that account for the possible interaction of multiple physical drivers when analysing high-impact events. Such an endeavour requires (i) a deeper understanding of the interplay of mechanisms causing Compound Events and (ii) an evaluation of the performance of climate/weather, statistical and impact models in representing Compound Events.
The European COST Action DAMOCLES coordinates these efforts by building a research network consisting of climate scientists, impact modellers, statisticians, and stakeholders. This session creates a platform for this network and acts as an introduction of the work related to DAMOCLES to the research community.
We invite papers studying all aspects of Compound Events, which might relate to (but are not limited to) the following topics:
Synthesis and Analysis: What are common features for different classes of Compound Events? Which climate variables need to be assessed jointly in order to address related impacts? How much is currently known about the dependence between these variables?
Stakeholders and science-user interface: Which events are most relevant for stakeholders? What are novel approaches to ensure continuous stakeholder engagement?
Impacts: What are the currently available sources of impact data? How can they be used to link observed impacts to climate and weather events?
Statistical approaches, model development and evaluation: What are possible novel statistical models that could be applied in the assessment of Compound Events?
Realistic model simulations of events: What are the physical mechanisms behind different types of Compound Events? What type of interactions result in the joint impact of the hazards that are involved in the event? How do these interactions influence risk assessment analyses?

The regional monsoons and the global monsoon circulation to which they belong have profound impacts on water, energy, and food security. Monsoons cause severe floods and droughts as well as undergoing variability on subseasonal, interannual and decadal-to-multi-decadal time scales. In addition to profound local effects, monsoon variability is also associated with global-scale impacts via teleconnections.
Monsoons are among the most complex phenomena involving coupled atmosphere-ocean-land interactions and remain notoriously difficult to forecast at leads times ranging from numerical weather prediction (NWP) to long-term climate projections. A better understanding of monsoon physics and dynamics, with more accurate simulation, prediction and projection of monsoon systems is therefore of great importance.
This session invites presentations on all aspects of monsoon research in present-day, future and palaeoclimate periods, involving observations, modelling, attribution, prediction and climate projection. Topics ranging from theoretical works based on idealized planets and ITCZ frameworks to the latest field campaign results are also invited, as is work on impacts, extremes, NWP modelling, S2S and decadal forecasting, and the latest CMIP6 findings.

Recent developments in machine learning (ML) are transforming Earth observation data analysis and modelling of the Earth system and its constituent processes. While statistical models have been used for a long time, state-of-the-art machine and deep learning algorithms allow encoding non-linear, spatio-temporal relationships robustly without sacrificing interpretability. These advances have the potential to accelerate climate science by improving our understanding of the underlying processes, reducing and better quantifying uncertainty, and even making predictions directly from observations across different spatio-temporal scales.
This session aims to provide a venue to present the latest progress in the use of ML applied to all aspects of climate science including, but not limited to:
- Causal discovery and inference
- Learning (causal) process and feature representations in observations
- Hybrid models (physically informed ML)
- Novel detection and attribution approaches
- Probabilistic modelling and uncertainty quantification
- Explainable AI applications to climate science
Please consider submitting abstracts focussed on ML for model improvement, particularly for near-term (including seasonal) forecasting to the companion “ML for Earth System modelling” session.
Unsupervised, supervised, semi-supervised as well as reinforcement learning are now increasingly used to address Earth system related challenges.
Machine learning could help extract information from numerous Earth System data, such as in-situ and satellite observations, as well as improve model fidelity through novel parameterisations or speed-ups. This session invites submissions spanning modelling and observational approaches towards providing an overview of the state-of-the-art of application of these novel methods for predicting and monitoring our earth system. This includes (but it is not restricted to):
- the use of machine learning to improve forecast skill
- generate significant speedups
- design new parameterization schemes
- emulate numerical models.
Please consider submitting abstracts focussed on ML applied to observations and modelling of climate processes to the companion "ML for Climate Science" session.
This interdisciplinary session welcomes contributions on novel conceptual and/or methodological approaches and methods for the analysis and statistical-dynamical modeling of observational as well as model time series from all geoscientific disciplines.
Methods to be discussed include, but are not limited to linear and nonlinear methods of time series analysis. time-frequency methods, statistical inference for nonlinear time series, including empirical inference of causal linkages from multivariate data, nonlinear statistical decomposition and related techniques for multivariate and spatio-temporal data, nonlinear correlation analysis and synchronisation, surrogate data techniques, filtering approaches and nonlinear methods of noise reduction, artificial intelligence and machine learning based analysis and prediction for univariate and multivariate time series.
Contributions on methodological developments and applications to problems across all geoscientific disciplines are equally encouraged. We particularly aim at fostering a transfer of new methodological data analysis and modeling concepts among different fields of the geosciences.

Statistical post-processing techniques for weather, climate, and hydrological forecasts are powerful approaches to compensate for effects of errors in model structure or initial conditions, and to calibrate inaccurately dispersed ensembles. These techniques are now an integral part of many forecasting suites and are used in many end-user applications such as wind energy production or flood warning systems. Many of these techniques are flourishing in the statistical, meteorological, climatological, hydrological, and engineering communities. The methods range in complexity from simple bias correction up to very sophisticated distribution-adjusting techniques that take into account correlations among the prognostic variables.
At the same time, a lot of efforts are put in combining multiple forecasting sources in order to get reliable and seamless forecasts on time ranges from minutes to weeks. Such blending techniques are currently developed in many meteorological centers.
In this session, we invite presentations dealing with both theoretical developments in statistical post-processing and evaluation of their performances in different practical applications oriented toward environmental predictions, and new developments dealing with the problem of combining or blending different types of forecasts in order to improve reliability from very short to long time scales.

Environmental systems often span spatial and temporal scales covering different orders of magnitude. The session is oriented toward collecting studies relevant to understand multiscale aspects of these systems and in proposing adequate multi-platform and inter-disciplinary surveillance networks monitoring tools systems. It is especially aimed to emphasize the interaction between environmental processes occurring at different scales. In particular, special attention is devoted to the studies focused on the development of new techniques and integrated instrumentation for multiscale monitoring of high natural risk areas, such as volcanic, seismic, energy exploitation, slope instability, floods, coastal instability, climate changes, and another environmental context.
We expect contributions derived from several disciplines, such as applied geophysics, geology, seismology, geodesy, geochemistry, remote and proximal sensing, volcanology, geotechnical, soil science, marine geology, oceanography, climatology, and meteorology. In this context, the contributions in analytical and numerical modeling of geological and environmental processes are also expected.
Finally, we stress that the inter-disciplinary studies that highlight the multiscale properties of natural processes analyzed and monitored by using several methodologies are welcome.

After the PhD, a new challenge begins: finding a position where you can continue your research or a
job outside academia where you can apply your advanced skills. This task is not
always easy, and frequently a general overview of the available positions is missing. Furthermore,
in some divisions, up to 70% of PhD graduates will go into work outside of academia. There are many
different careers which require or benefit from a research background. But often, students and
early career scientists struggle to make the transition due to reduced support and networking.
In this panel discussion, scientists with a range of backgrounds give their advice on where to find
jobs, how to transition between academia and industry and what are the pros and cons of a career
inside and outside of academia.
In the final section of the short course, a Q+A will provide the audience with a chance to ask
their questions to the panel. This panel discussion is aimed at early career scientists but anyone
with an interest in a change of career will find it useful. An extension of this short course will
run in the networking and early career scientist lounge, for further in-depth or
one-on-one questions with panel members.

On 9 August 2021, the Intergovernmental Panel on Climate Change (IPCC) released the first volume of its 6th Assessment Report (AR6). The Working Group I contribution to the Report (Climate Change 2021: The Physical Science Basis) synthesises over 14,000 publications and represents the most comprehensive and up-to-date assessment of the climate system and climate change. Crucially, the Report highlights the unprecedented and potentially irreversible influence of anthropogenic climate forcing, and for the first time, explicitly states that human influence on the climate system is unequivocal.
This short course will be a panel discussion where authors and contributors of Working Group I unpack how the IPCC 6th Assessment Report (AR6) is produced, provide personal behind-the-scenes insight on its development, and discuss its global impact, including how it is used to inform policy. Authors of the report will share their experiences of working on the report before and through the COVID pandemic. Panelists will also emphasise various ways in which scientists of all career stages can contribute to the IPCC process. Ample time will be allocated for open discussion for the audience to ask related questions to the panelists.
For more information about the AR6 please visit the IPCC website: https://www.ipcc.ch/.
Observations and measurements of geophysical systems and dynamical phenomena are obtained as time series or spatio-temporal data whose dynamics usually manifests a nonlinear multiscale (in terms of time and space) behavior. During the past decades, nonlinear approaches in geosciences have rapidly developed to gain novel insights on weather and climate dynamics, fluid dynamics, on turbulence and stochastic behaviors, on the development of chaos in dynamical systems, and on concepts of networks, nowadays frequently employed in geosciences.
In this short course, we will offer a broad overview of the development and application of nonlinear concepts across the geosciences in terms of recent successful applications from various fields, ranging from climate to near-Earth space physics. The focus will be on a comparison between different methods to investigate various aspects of both known and unknown physical processes, moving from past accomplishments to future challenges.

The climate system as a whole can be viewed as a highly complex thermal/heat engine, in which numerous processes continuously interact to transform heat into work and vice-versa. As any physical system, the climate system obeys the basic laws of thermodynamics, and we may therefore expect the tools of non-equilibrium thermodynamics to be particularly useful in describing and synthesising its properties. The main aim of this short course will be twofold. Part 1 will provide an advanced introduction to the fundamentals of equilibrium and non-equilibrium thermodynamics, irreversible processes and energetics of multicomponent stratified fluids. Part 2 will illustrate the usefulness of this viewpoint to summarize the main features of the climate system in terms of thermodynamic cycles, as well as a diagnostic tool to constrain the behavior of climate models. Although the aim is for this to be a self-contained module, some basic knowledge of the subject would be beneficial to the participants.
- The first part, chaired by Remi Tailleux, will provide an advanced introduction on the fundamentals of equilibrium and non-equilibrium thermodynamics, irreversible processes and energetics.
- The second part, chaired by Valerio Lembo and Gabriele Messori, will illustrate some applications of thermodynamics to the study of the climate system and its general circulation.

The short course will be structured as such: - Part 1 (45 mins): theoretical background, by Remi Tailleux;
- Short break (5 mins);
- Part 2 (15 mins): diagnosing thermodynamics in climate models, by Valerio Lembo;
- Part 3 (10 mins): dynamics and heat transports in the atmosphere, by Gabriele Messori;
The climate is highly variable over wide ranges of scale in both space and time so that the amplitude of changes systematically depends on the scale of observations. As a consequence, climate variations recorded in time series or spatial distributions, which are produced through modelling or empirical analyses are inextricably linked to their space-time scales and is a significant part of the uncertainties in the proxy approaches. Rather than treating the variability as a limitation to our knowledge, as a distraction from mechanistic explanations and theories, in this course the variability is treated as an important, fundamental aspect of the climate dynamics that must be understood and modelled in its own right. Long considered as no more than an uninteresting spectral “background”, modern data shows that in fact it contains most of the variance.
We review techniques that make it possible to systematically analyse and model the variability of instrumental and proxy data, the inferred climate variables and the outputs of GCM’s. These analyses enable us to cover wide ranges of scale in both space and in time - and jointly in space-time - without trivializing the links between the measurements, proxies and the state variables (temperature, precipitation etc.). They promise to systematically allow us to compare model outputs with data, to understand the climate processes from small to large and from fast to slow. Specific tools that will be covered include spectral analysis, scaling fluctuation analysis, wavelets, fractals, multifractals, and stochastic modeling; we discuss corresponding software. We also include new developments in the Fractional Energy Balance Equation approach that combines energy and scale symmetries.

Age models are applied in paleoclimatological, paleogeographic and geomorphologic studies to understand the timing of climatic and environmental change. Multiple independent geochronological dating methods are available to generate robust age models. For example, different kinds of radio isotopic dating, magneto-, bio-, cyclostratigraphy and sedimentological relationships along stratigraphic successions or in different landscape contexts. The integration of these different kinds of geochronological information often poses challenges.
Age-depth or chronological landscape models are the ultimate result of the integration of different geochronological techniques and range from linear interpolation to more complex Bayesian techniques. Invited speakers will share their experience in several modelling concepts and their application in a range of Quaternary paleoenvironmental and geomorphologic records. The Short Course will provide an overview of age models and the problems one encounters in climate science and geomorphology. Case studies and practical examples are given to present solutions for these challenges. It will prepare the participants from CL, GM and other divisions for independent application of suitable age-depth models to their climate or geomorphologic data.

Within this course, the attendees are taught how to identify possible cyclicities in paleoclimate data (e.g., sediments, speleothems) or any other geological record. We will start from the basics of which data can be analysed, go over power spectra, and discuss the application of filters and Wavelet Analysis. We will discuss the advantages and disadvantages of different methods, and give some examples from Earth Sciences to highlight common pitfalls. The aim of this course is to give a brief overview of the most common techniques and give participants the insight to prepare and analyse their data themselves. A variety of computational platforms are available for time-series analysis. In this course, we will introduce different tools and techniques by making use of the programming language R.

This Short Course is aimed at researchers in climate-related domains, who have an interest in working with climate data. We will introduce the ESMValTool, a Python project developed to facilitate the analysis of climate data through so-called recipes. An ESMValTool recipe specifies which input data will be used, which preprocessor functions will be applied, and which analytics should be computed. As such, it enables readable and reproducible workflows. The tool takes care of finding, downloading, and preparing data for analysis. It includes a suite of preprocessing functions for commonly used operations on the input data, such as regridding or computation of various statistics, as well as a large collection of established analytics.
In this course, we will run some of the available example recipes using ESMValTool’s convenient Jupyter notebook interface. You will learn how to customize the examples, in order to get started with implementing your own analysis. A number of core developers of ESMValTool will be present to answer any and all questions you may have.
The ESMValTool has been designed to analyze the data produced by Earth System Models participating in the Coupled Model Intercomparison Project (CMIP), but it also supports commonly used observational and re-analysis climate datasets, such as ERA5. Version 2 of the ESMValTool has been specifically developed to target the increased data volume and complexity of CMIP Phase 6 (CMIP6) datasets. ESMValTool comes with a large number of well-established analytics, such as those in Chapter 9 of the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) (Flato et al., 2013) and has been extensively used in preparing the figures of the Sixth Assessment Report (AR6). In this way, the evaluation of model results can be made more efficient, thereby enabling scientists to focus on developing more innovative methods of analysis rather than constantly having to "reinvent the wheel".

Glaciers and ice caps are major contributors to sea-level rise and have large impacts on runoff from glacierized basins. Major mass losses of glaciers and ice caps have been reported around the globe for the recent decades. This is a general session on glaciers outside the Greenland and Antarctic ice sheets, emphasizing their past, present and future responses to climate change. Although much progress in understanding the link between glaciers and climate and the impacts of their wastage on various systems has recently been achieved, many substantial unknowns remain. It is necessary to acquire more direct observations, both applying novel measurement technologies and releasing unpublished data from previous years, as well as combining in situ observations with new remote sensing products and modelling. In order to improve our understanding of the processes behind the observed glacier changes, the application of models of different complexity in combination with new data sets is crucial. We welcome contributions on all aspects of glacier changes – current, past and future – based on field observations, remote sensing and modelling. Studies on the physical processes controlling all components of glacier mass balance are especially encouraged, as well as assessments of the impact of retreating glaciers and ice caps on sea-level rise, runoff and other downstream systems.

This session explores improvements in our understanding and quantification of past, present and future ice sheet and sea-level changes. We invite contributions around the following topics: How to improve the reliability of the projections using observations (paleo and present), models and model intercomparison exercises (ISMIP6 results, MISOMIP, …); assessment of uncertainties and probability distributions of the ice sheets' contribution to sea level change; emerging processes; feedbacks coming from interactions between components (ice sheets, ocean, atmosphere, solid earth). We focus on the present and future (multi-centennial) Greenland and Antarctic ice sheets, but paleo-studies are encouraged if they shed a light on the mentioned topics. This session is related to both ISMASS (http://www.climate-cryosphere.org/activities/groups/ismass) and ISMIP6 (http://www.climate-cryosphere.org/activities/targeted/ismip6).

The increasing availability of remotely sensed observations and computational capacity, drive modelling and observational glacier studies towards increasingly large spatial scales. These large scales are of particular relevance, as they impact policy decisions and public discourse. In the European Alps, for instance, glacier changes are important from a touristic perspective, while in High Mountain Asia, glaciers are a key in the region’s hydrological cycle. At a global scale, glaciers are among the most important contributors to present-day sea level change.
This session focuses on advances in observing and modelling mountain glaciers and ice caps at the regional to global scale. We invite both observation- and modelling-based contributions that lead to a more complete understanding of glacier changes and dynamics at such scales.
Contributions may include, but are not limited to, the following topics:
• Observation and modelling results revealing previously unappreciated regional differences in glacier changes or in their dynamics;
• Large-scale impact studies, including glaciers' contribution to sea level change, or changes in water availability from glacierized regions;
• Advances in regional- to global-scale glacier models, e.g. inclusion of physical processes such as ice dynamics, debris-cover effects, glacier calving, or glacier surging;
• Regional to global scale process-studies, based on remote sensing observations or meta-analyses of ground-based data;
• Strategies to facilitate or systematise the information flow of observations into models (e.g. blending/homogenisation of different remote sensing products, machine learning algorithms, inverse techniques, data assimilation);
• Inverse modelling of subglacial characteristics or glacier ice thickness at regional scales.
The largest single source of uncertainty in projections of future global sea level is associated with the mass balance of the Antarctic Ice Sheet (AIS). In the short-term, it cannot be stated with certainty whether the mass balance of the AIS is positive or negative; in the long-term, the possibility exists that melting of the coastal shelves around Antarctica will lead to an irreversible commitment to ongoing sea level rise. Observational and paleoclimate studies can help to reduce this uncertainty, constraining the parameterizations of physical processes within ice sheet models and allowing for improved projections of future global sea level rise. This session welcomes presentations covering all aspects of observation, paleoclimate reconstruction and modeling of the AIS. Presentations that focus on the mass balance of the AIS and its contribution towards changes in global sea level are particularly encouraged.
Geophysical and in-situ measurements offer important baseline datasets, as well as validation for modelling and remote sensing products. They are used to advance our understanding of firn, ice-sheet and glacier dynamics, sea ice processes, changes in snow cover and snow properties, snow/ice-atmosphere-ocean interactions, permafrost degradation, geomorphic mechanisms and changes in englacial and subglacial condition.
In this session we welcome contributions related to a wide spectrum of methods, including, but not limited to, advances in radioglaciology, active and passive seismology, geoelectrics, acoustic sounding, fiber-optic sensing, GNSS reflectometry, signal attenuation and time delay techniques, cosmic ray neutron sensing, ROV and drone applications, and electromagnetic methods. Contributions could be related to field applications, new approaches in geophysical or in-situ survey techniques, or theoretical advances in data analysis processing or inversion. Case studies from all parts of the cryosphere such as snow and firn, alpine glaciers, ice sheets, glacial and periglacial environments, permafrost, or sea ice, are highly welcome.
The focus of the session is to compare experiences in the application, processing, analysis and interpretation of different geophysical and in-situ techniques in these highly complex environments. We have been running this session for nearly a decade and it always produces lively and informative discussion. This session is offered as a fully hybrid vPICO: an engaging presentation format in which all authors will present their research orally as a quick-fire 2-minute overview, and then further present and discuss their research.

Process understanding is key to assessing the sensitivity of glacier systems to changing climate. Comprehensive glacier monitoring provides the base for large-scale assessment of glacier distribution and changes. Glaciers are observed on different spatio-temporal scales, from extensive seasonal mass-balance studies at individual glaciers to decadal assessments of glacier mass changes and repeat inventories at the scale of entire mountain ranges. Internationally coordinated glacier monitoring aims at combining in-situ measurement with remotely sensed data, and local process understanding with global coverage. We invite contributions from a variety of disciplines, from tropical to polar glaciers, addressing both in-situ and remotely sensed monitoring of past and current glacier distribution and changes, as well as related uncertainty assessments. A special focus of this year’s session shall be on (i) strengths and limitations of different types of satellite data for global and regional glacier surveys, (ii) achieving a better temporal resolution of global and regional surveys (iii) how to develop in-situ networks for real-time monitoring of glacier changes and (iv) advances in studies on local process understanding and how best to combine them with regional to global change assessments?. An additional focus this year relates to improving understanding of debris-covered glaciers from in-situ and remote sensing methods, as well as understanding their long-term dynamics with numerical models.
This session will focus on recent and upcoming advances in satellite remote sensing of the global cryosphere. We welcome presentations providing new insights into cryospheric processes in the broadest sense, ranging from ice sheets, glaciers, snow cover and its properties, frozen soil, sea ice and extraterrestrial glaciology. While the advent of remote sensing has revolutionized the field of glaciology, a vast reservoir of potential remains to be unlocked by using these observations in concert with other data sets. We particularly encourage presentations discussing multi-platform data merging, integration of GIS and ground validation data, integration of remote sensing data into earth system models, as well as cloud computing and processing of super large data sets. We also encourage contributions focusing on historic satellite data re-analysis, novel processing approaches for upcoming satellite missions, and presentations outlining pathways to next-generation satellite missions for the coming decades.

Snow constitutes a freshwater resource for over a billion of people world-wide. High percentage of this water resource mainly come from seasonal snow located in mid-latitude regions. The current warming situation alerts that these snow water storages are in high risk to be dramatically reduced, affecting not only to water supply but also ecosystem over these areas. Therefore, understanding seasonal snow dynamics, possible changes and implication have become crucial for water resources management. Remote sensing has proven to be the main technique used to monitor the snow properties across mid-large extensions and their hydrological implications, for decades now. Moreover, the recent advances, which are focused on the study of snow properties at higher spatio-temporal scales (e.g., small-scale snow-topography interactions, snow-vegetation interaction, diurnal variation of snow, rain over snow events), are helping to understand better snow acumulation, distribution and ablation dynamics.
This session is focused on studies linking the use of remote sensing of seasonal snow in hydrological applications: techniques and data from different technologies, such as time-lapse imagery, laser scanners, radar, optical photography, thermal and hyperspectral technologies, or other new applications, with the aim of quantifying and better understanding snow characteristics (i.e. snow grain size, snow depth, albedo, pollution load, snow specific area and snow density), snow related processes (snowfall, melting, evaporation and sublimation), snow dynamics, snow hydrological impacts and snow environmental effects.

Satellite altimetry provides the possibility to observe key parts of the hydrosphere, namely the ocean, ice, and continental surface water from space. Since the launch of Topex/Poseidon in 1992, the applications of altimetry have expanded from the open oceans to coastal zones, inland water, land, and sea ice. Today, seven missions are in orbit, providing dense and near-global observations of surface elevation and several other parameters. Satellite altimetry has become an integral part of the global observation of the Earth‘s system and changes therein.
In recent years, new satellite altimetry missions have been launched carrying new instruments; the CryoSat-2/Sentinel-3 missions equipped with a Delay/Doppler altimeter, the Saral AltiKa mission carrying the first Ka-band altimeter, and 2018 launched six beam photon-counting laser altimeter onboard NASAs ICESat-2. Further, new orbits with high inclination and long-repeat time are used for CryoSat-2 and ICESat-2.
Fully exploiting this unprecedented availability of observables will enable new applications and results but also require novel and adapted methods of data analysis.
Across the different applications for satellite altimetry, the data analysis and underlying methods are similar and a knowledge exchange between the disciplines has been proofed to be fruitful.
In this multidisciplinary altimetry session, we therefore invite contributions which discuss new methodology and applications for satellite altimetry in the fields of geodesy, hydrology, cryosphere, oceanography, and climatology.
Topics of such studies could for example be (but not limited to); creation of robust and consistent time series across sensors, validation experiments, combination of radar and laser altimetry for e.g. remote sensing of snow, classification of waveforms, application of data in a geodetic orbit, retracking, or combination with other remote sensing data sets.
Ice cores are a crucial archive to study past climates, containing various proxies which provide insights into the variability of atmospheric circulation and composition, past temperatures, volcanic activity, biological production and sea ice extent on different timescales. The accuracy and reliability of reconstructed climate parameters, however, depends on a detailed understanding of the processes forming the proxy signal. Relevant processes might not be the same throughout time, and could be variable on a spatial scale, i.e. different for ice core sites in Antarctica, Greenland, Svalbard or high alpine areas. In light of new projects that will analyse very old ice (e.g. Beyond EPICA Oldest Ice), it is even more important to understand the archival of climatic signals in proxies, such as stable water isotopes, impurities, dust, tephra, gases and trace elements in order to develop suitable methods for the recovery of the original climate signal.
This session intends to foster cross-disciplinary exchanges of paleoclimatologists working on established and novel climate proxies in ice cores and their interpretation. We welcome contributions that investigate the transfer function between climate and ice core proxies describing both the primary climatic imprint at the surface and potential secondary, post-depositional modifications of proxy records. We invite submissions from, but not limited to, field studies and lab experiments on the primary signal formation, theoretical simulations and proxy system modeling, as well as studies investigating the role of secondary processes modifying the original climate signal, and methodologies to optimally retrieve information from disrupted or altered proxy records (e.g. through melt events, transport and diffusion). We further encourage submissions presenting novel statistical methods, model-based studies and potential geochemical proxies.

Machine learning, artificial intelligence and big data approaches have recently emerged as key tools in understanding the cryosphere. These approaches are being increasingly applied to answer long standing questions in cryospheric science, including those relating to remote sensing, forecasting, and improving process understanding across Antarctic, Arctic and Alpine regions. In doing so, data science and AI techniques are being used to gain insight into system complexity, analyse data on unprecedented temporal and spatial scales, and explore much wider parameter spaces than were previously possible.
In this session we invite submissions that utilise data science and/or AI techniques that address research questions relating to glaciology, sea ice, permafrost and/or polar climate science. Approaches used may include (but are not limited to) machine learning, artificial intelligence, big data processing/automation techniques, advanced statistics, and innovative software/computing solutions. These could be applied to any (or combinations) of data sources including remote sensing, numerical model output and field/lab observations. We particularly invite contributions that apply techniques and approaches that reveal new insights into cryospheric research problems that would not otherwise be achievable using traditional methods, and those that discuss how or if approaches can be applied or adapted to other areas of cryospheric science. Given the rapid development of this field by a diverse group of international researchers, we convene this session to help foster future collaboration amongst session contributors, attendees, and international stakeholders and help address the most challenging questions in cryospheric science.

This interdisciplinary session brings together modellers and observationalists to present results and exchange knowledge and experience in the use of inverse methods, geostatistics and data assimilation - including machine learning - in cryospheric science.
In numerous research fields it is now possible not only to deduce static features of a physical system but also to retrieve information on transient processes between different states or even regime shifts. In the cryospheric sciences a large potential for future developments lies at the intersection of observations and models with the aim to yield prognostic capabilities in space and time. Compared to other geoscientific disciplines like meteorology or oceanography, where techniques such as data assimilation have been well established for decades, in cryospheric sciences only the foundation has been laid for the use of these techniques, one reason often being the sparsity of observations.
We invite contributions from a wide range of methodologies - from satellite observations to deep-looking geophysical methods and advancements in numerical techniques, and from topics including permafrost, sea ice and snow to glaciers and ice sheets, covering static system characterisations as well as transient processes.

This session invites innovative Earth system and climate studies based on geodetic measuring techniques. Modern geodetic observing systems document a wide range of changes in the Earth’s solid and fluid layers at very diverging spatial and temporal scales related to processes as, e.g., glacial isostatic adjustment, the terrestrial water cycle, ocean dynamics and ice-mass balance. Different time spans of observations need to be cross-compared and combined to resolve a wide spectrum of climate-related signals. Geodetic observables are also often compared with geophysical models, which helps to explain observations, evaluate simulations, and finally merge measurements and numerical models via data assimilation.
We appreciate contributions utilizing geodetic data from diverse geodetic satellites including altimetry, gravimetry (CHAMP, GRACE, GOCE and GRACE-FO), navigation satellite systems (GNSS and DORIS) or remote sensing techniques that are based on both passive (i.e., optical and hyperspectral) and active (i.e., SAR) instruments. We welcome studies that cover a wide variety of applications of geodetic measurements and their combination to observe and model Earth system signals in hydrological, ocean, atmospheric, climate and cryospheric sciences. Any new approaches helping to separate and interpret the variety of geophysical signals are equally appreciated. Contributions working towards any of the goals of the Inter-Commission Committee on "Geodesy for Climate Research" (ICCC) of the International Association of Geodesy (IAG) are also welcomed in this session.
With author consent, highlights from this session will be tweeted with a dedicated hashtag during the conference in order to increase the impact of the session.

Recent advances in image collection, e.g. using unoccupied aerial vehicles (UAVs), and topographic measurements, e.g. using terrestrial or airborne LiDAR, are providing an unprecedented insight into landscape and process characterization in geosciences. In parallel, historical data including terrestrial, aerial, and satellite photos as well as historical digital elevation models (DEMs), can extend high-resolution time series and offer exciting potential to distinguish anthropogenic from natural causes of environmental change and to reconstruct the long-term evolution of the surface from local to regional scale.
For both historic and contemporary scenarios, the rise of techniques with ‘structure from motion’ (SfM) processing has democratized data processing and offers a new measurement paradigm to geoscientists. Photogrammetric and remote sensing data are now available on spatial scales from millimetres to kilometres and over durations of single events to lasting time series (e.g. from sub-second to decadal-duration time-lapse), allowing the evaluation of event magnitude and frequency interrelationships.
The session welcomes contributions from a broad range of geoscience disciplines such as geomorphology, cryosphere, volcanology, hydrology, bio-geosciences, and geology, addressing methodological and applied studies. Our goal is to create a diversified and interdisciplinary session to explore the potential, limitations, and challenges of topographic and orthoimage datasets for the reconstruction and interpretation of past and present 2D and 3D changes in different environments and processes. We further encourage contributions describing workflows that optimize data acquisition and processing to guarantee acceptable accuracies and to automate data application (e.g. geomorphic feature detection and tracking), and field-based experimental studies using novel multi-instrument and multi-scale methodologies. This session invites contributions on the state of the art and the latest developments in i) modern photogrammetric and topographic measurements, ii) remote sensing techniques as well as applications, iii) time-series processing and analysis, and iv) modelling and data processing tools, for instance, using machine learning approaches.
Snow cover characteristics (e.g. spatial distribution, surface and internal physical properties) are continuously evolving over a wide range of scales due to meteorological conditions, such as precipitation, wind and radiation.
Most processes occurring in the snow cover depend on the vertical and horizontal distribution of its physical properties, which are primarily controlled by the microstructure of snow (e.g. density, specific surface area). In turn, snow metamorphism changes the microstructure, leading to feedback loops that affect the snow cover on coarser scales. This can have far-reaching implications for a wide range of applications, including snow hydrology, weather forecasting, climate modelling, and avalanche hazard forecasting or remote sensing of snow. The characterization of snow thus demands synergetic investigations of the hierarchy of processes across the scales ranging from explicit microstructure-based studies to sub-grid parameterizations for unresolved processes in large-scale phenomena (e.g. albedo, drifting snow).
This session is therefore devoted to modelling and measuring snow processes across scales. The aim is to gather researchers from various disciplines to share their expertise on snow processes in seasonal and perennial snowpacks. We invite contributions ranging from “small” scales, as encountered in microstructure studies, over “intermediate” scales typically relevant for 1D snowpack models, up to “coarse” scales, that typically emerge for spatially distributed modelling over mountainous or polar snow- and ice-covered terrain. Specifically, we welcome contributions reporting results from field, laboratory and numerical studies of the physical and chemical evolution of snowpacks, statistical or dynamic downscaling methods of atmospheric driving data, assimilation of in-situ and remotely sensed observations, representation of sub-grid processes in coarse-scale models, and evaluation of model performance and associated uncertainties.
Snow avalanches range among the most prominent natural hazards which threaten mountain communities worldwide. Snow avalanche formation is a complex critical phenomenon which starts with failure processes at the scale of snow crystals and ends with the release of a large volume of snow at a scale of up to several hundred meters. The practical application of avalanche formation is avalanche forecasting, requiring a thorough understanding of the physical and mechanical properties of snow as well as the influence of meteorological boundary conditions (e.g. precipitation, wind and radiation). This session aims to improve our understanding of avalanche formation processes and to foster the application to avalanche forecasting. This session is also devoted to the dynamics of dense and powder snow avalanches and their accompanying transitional regimes. One focus is their interaction with, and impact on, vulnerable elements, such as buildings, protection dams, forests, and roads.
We welcome novel experimental and computational contributions including, but not limited to the topics of spatial variability, avalanche release mechanics, remote avalanche detection, avalanche forecasting, physical vulnerability of structures impacted by snow avalanches, avalanche hazard zoning and avalanche mitigation strategies.
The global cryosphere with all its components is strongly impacted by climate change and has been undergoing significant changes over the past decades. Glaciers are shrinking and thinning. Snow cover and duration is reduced, and permafrost, in both Arctic and mountain environments, is thawing. Changes in sea ice cover and characteristics have attracted widespread attention, and changes in ice sheets are monitored with care and concern. Risks associated with one or several of these cryosphere components have been present throughout history. However, with ongoing climate change, we expect changes in the magnitude and frequency of hazards with profound implications for risks, especially when these interact with other aspects relating to context vulnerability, exposure, and other processes of biophysical and/or socioeconomic drivers of change. New or growing glacier lakes pose a threat to downstream communities through the potential for sudden drainage. Thawing permafrost can destabilize mountain slopes, and eventually result in large landslide or destructive rock and ice avalanches. An accelerated rate of permafrost degradation in low-land areas poses risk to existing and planned infrastructure and raises concerns about large-scale emission of greenhouse gases currently trapped in Arctic permafrost. Decreased summertime sea ice extent may produce both risks and opportunities in terms of large-scale climate feedbacks and alterations, coastal vulnerability, and new access to transport routes and natural resources. Furthermore, rapid acceleration of outlet glacier ice discharge and collapse of ice sheets is of major concern for sea level change. This session invites contributions across all cryosphere components that address risks associated with observed or projected physical processes. Contributions considering more than one cryosphere component (e.g. glaciers and permafrost) are particularly encouraged, as well as contributions on cascading processes and interconnected risks. Contributions can consider hazards and risks related to changes in the past, present or future. Furthermore, Contributions may consider one or several components of risks (i.e. natural hazards, exposure, vulnerability) as long as conceptual clarity is ensured. Furthermore, cases that explore diverse experiences with inter- and transdisciplinary research, that sought to address these risks with communities through adaptation and resilience building, are also be considered.

Water stored in the snow pack and in glaciers represents an important component of the hydrological budget in many regions of the world, as well as a sustainment to life during dry seasons. Predicted impacts of climate change in catchments covered by snow or glaciers (including a shift from snow to rain, earlier snowmelt, and a decrease in peak snow accumulation) will reflect both on water resources availability and water uses at multiple scales, with potential implications for energy and food production.
The generation of runoff in catchments that are impacted by snow or ice, profoundly differs from rainfed catchments. And yet, our knowledge of snow/ice accumulation and melt patterns and their impact on runoff is highly uncertain, because of both limited availability and inherently large spatial variability of hydrological and weather data in such areas. This translates into limited process understanding, especially in a warming climate.
This session aims at bringing together those scientists that define themselves to some extent as cold region hydrologists, as large as this field can be. Contributions addressing the following topics are welcome:
- Experimental research on snow-melt & ice-melt runoff processes and potential implementation in hydrological models;
- Development of novel strategies for snowmelt runoff modelling in various (or changing) climatic and land-cover conditions;
- Evaluation of remote-sensing or in-situ snow products and application for snowmelt runoff calibration, data assimilation, streamflow forecasting or snow and ice physical properties quantification;
- Observational and modelling studies that shed new light on hydrological processes in glacier-covered catchments, e.g. impacts of glacier retreat on water resources and water storage dynamics or the application of techniques for tracing water flow paths;
- Studies on cryosphere-influenced mountain hydrology, such as landforms at high elevations and their relationship with streamflow, water balance of snow/ice-dominated mountain regions;
- Studies addressing the impact of climate change on the water cycle of snow and ice affected catchments.

Glaciers and volcanoes interact in a number of ways, including instances where volcanic/geothermal activity alters glacier dynamics or mass balance, via subglacial eruptions or the deposition of supraglacial tephra. Glaciers can also impact volcanism, for example by directly influencing mechanisms of individual eruptions resulting in the construction of distinct edifices. Glaciers may also influence patterns of eruptive activity when mass balance changes adjust the load on volcanic systems, the water resources and hydrothermal systems. However, because of the remoteness of many glacio-volcanic environments, these interactions remain poorly understood.
In these complex settings, hazards associated with glacier-volcano interaction can vary from lava flows to volcanic ash, lahars, landslides, pyroclastic flows or glacial outburst floods. These can happen consecutively or simultaneously and affect not only the earth, but also glaciers, rivers and the atmosphere. As accumulating, melting, ripping or drifting glaciers generate signals as well as degassing, inflating/ deflating or erupting volcanoes, the challenge is to study, understand and ultimately discriminate these potentially coexisting signals. We wish to fully include geophysical observations of current and recent events with geological observations and interpretations of deposits of past events. Glaciovolcanoes also often preserve a unique record of the glacial or non-glacial eruptive environment that is capable of significantly advancing our knowledge of how Earth's climate system evolves.
We invite contributions that deal with the mitigation of the hazards associated with ice-covered volcanoes in the Arctic, Antarctic or globally, that improve the understanding of signals generated by ice-covered volcanoes, or studies focused on volcanic impacts on glaciers and vice versa. Research on recent activity is especially welcomed. This includes geological observations e.g. of deposits in the field or remote-sensing data, together with experimental and modelling approaches. We also invite contributions from any part of the world on past activity, glaciovolcanic deposits and studies that address climate and environmental change through glaciovolcanic studies. We aim to bring together scientists from volcanology, glaciology, seismology, geodesy, hydrology, geomorphology and atmospheric science in order to enable a broad discussion and interaction.

Ice sheets play an active role in the climate system by amplifying, pacing, and potentially driving global climate change over a wide range of time scales. The impact of interactions between ice sheets and climate include changes in atmospheric and ocean temperatures and circulation, global biogeochemical cycles, the global hydrological cycle, vegetation, sea level, and land-surface albedo, which in turn cause additional feedbacks in the climate system. This session will present data and modelling results that examine ice sheet interactions with other components of the climate system over several time scales. Among other topics, issues to be addressed in this session include ice sheet-climate interactions from glacial-interglacial to millennial and centennial time scales, the role of ice sheets in Cenozoic global cooling and the mid-Pleistocene transition, reconstructions of past ice sheets and sea level, the current and future evolution of the ice sheets, and the role of ice sheets in abrupt climate change.
Glacial Isostatic Adjustment (GIA) describes the dynamic response of the solid Earth to ice sheet glaciation/deglaciation, which affects the spatial and temporal sea level changes, and induces surface deformation, gravitational field variation and stress changes in the subsurface. The process is influenced by the ice sheet characteristics (e.g., extent, volume, grounding line) and solid Earth structure. With more observational data (e.g., relative sea-level data, GPS data, tide gauges, terrestrial and satellite gravimetry, glacially induced faults) are available/standardized, we can better investigate the interactions between the ice sheets, solid Earth and sea levels, and reveal the ice sheet and sea-level evolution histories and rheological properties of the Earth.
This session invites contributions discussing observations, analysis, and modelling of ice sheet dynamics, solid Earth response, and the resulting global, regional and local sea-level changes and land deformation, including paleo ice sheet and paleo sea-level investigations, geodetic measurements of crustal motion and gravitational change, GIA modelling with complex Earth models (e.g., 3D viscosity, non-linear rheologies) and coupled ice-sheet/Earth modelling, investigations on glacially triggered faulting as well as the Earth’s elastic response to present-day ice mass changes. We also welcome abstracts that address the future ice sheets/shelves evolution and sea-level projection as well as GIA effects on oil migration and nuclear waste repositories. Contributions related to both polar regions and previously glaciated regions are welcomed. This session is co-sponsored by the SCAR sub-committee INSTANT-EIS, Earth - Ice - Sea level, in view of instabilities and thresholds in Antarctica https://www.scar.org/science/instant/home/.
Ice shelves and tidewater glaciers are sensitive elements of the climate system. Sandwiched between atmosphere and ocean, they are vulnerable to changes in either. The recent disintegration of ice shelves such as Larsen B and Wilkins on the Antarctic Peninsula, current thinning of the ice shelves in the Amundsen Sea sector of West Antarctica, and the recent accelerations of many of Greenland's tidewater glaciers provide evidence of the rapidity with which those systems can respond. Changes in marine-terminating outlets appear to be intimately linked with acceleration and thinning of the ice sheets inland of the grounding line, with immediate consequences for global sea level. Studies of the dynamics and structure of the ice sheets' marine termini and their interactions with atmosphere and ocean are the key to improving our understanding of their response to climate forcing and of their buttressing role for ice streams. The main themes of this session are the dynamics of ice shelves and tidewater glaciers and their interaction with the ocean, atmosphere and the inland ice, including grounding line dynamics. The session includes studies on related processes such as calving, ice fracture, rifting and mass balance, as well as theoretical descriptions of mechanical and thermodynamic processes. We seek contributions both from numerical modelling of ice shelves and tidewater glaciers, including their oceanic and atmospheric environments, and from observational studies of those systems, including glaciological and oceanographic field measurements, as well as remote sensing and laboratory studies.

Supraglacial and subglacial processes play a key role in the structure, motion and stability of Earth’s ice masses. Such processes broadly relate to supraglacial hydrology (concerning the generation and movement of meltwater at the ice surface), subglacial hydrology (including the formation and operation of flow pathways beneath the ice), and subglacial processes (including deformation and erosion and its consequences for ice mass motion and the glacial-geomorphological record). This session brings together observational and modelling contributions that concern any such processes and/or interactions between them.
This session is a merger of initial sessions CR4.4 ‘Subglacial environment of ice sheets and glaciers’ and CR4.5 ‘Hydrology of ice shelves, ice sheets and glaciers - from the surface to the base’. The session is divided into three time blocks: (1) supraglacial hydrology, (2) subglacial hydrology, and (3) subglacial sedimentary processes.

About 800 Pg soil carbon has been frozen for centuries to millennia. A large fraction of it is assumed to be thawed due to climate change in the near future. A rapid mineralization of this carbon to carbon dioxide or methane will directly alter the global carbon cycle resulting in positive feedback mechanisms that even accelerate climate change. However, permafrost-affected soils and the organic matter stored within are distributed heterogeneously with depth and across ecosystems. Is such thawing organic matter accessible to microorganisms and vulnerable to microbial decay, and hence will it be decomposed fast? Will a large part of it be stabilized at mineral surfaces or in soil aggregates, or will stabilization processes known from temperate soils be rather ineffective? Furthermore, what is the effect of hydrological changes to carbon mineralization or stabilization, particularly with respect to energy constraints of microorganisms? What will be effects of changing vegetation functions to soil organic matter dynamics? This session invites papers that investigate decomposition versus stabilization of thawing permafrost or active layer-organic matter. Contributions may be based on laboratory experiments, field observations, or modelling from the process level to the global scale.

Wide-spread permafrost thaw is expected to amplify the release of previously frozen material from terrestrial into aquatic systems: rivers, lakes, groundwater and oceans. Current projections include changes in precipitation patterns, active layer drainage and leaching, increased thermokarst lake formation, as well as increased coastal and river bank erosion that are further enhanced by rising water temperatures, river discharge and wave action. In addition, subsea permafrost that formed under terrestrial conditions but was later inundated might be rapidly thawing on Arctic Ocean shelves. These processes are expected to substantially alter the biogeochemical cycling of carbon but also of other elements in the permafrost area.
This session invites contributions on the mobilization of terrestrial matter to aquatic systems in the permafrost domain, as well as its transport, degradation and potential interaction with autochthonous, aquatic matter. We encourage submissions focusing on organic and inorganic carbon as well as on other elements such as nitrogen, phosphorus, silica, iron, mercury and others, from all parts of the global permafrost area including mountain, inland, coastal and subsea permafrost, on all spatial scales, in the contemporary system but also in the past and future, based on field, laboratory and modelling work.

The geological records of glaciations provide information on the Earth’s past climate and on the efficiency of glaciers in modifying landscapes. Traces of glacial activity are manifested in characteristic depositional and erosional landforms. The focus of this session is to stimulate discussions about the challenges and advances in understanding glaciations and glacial records with a special emphasis on the Quaternary period: How do landscapes and erosion rates evolve under the repeated impact of glaciations? What is the impact of early vs. late glaciations during an ice age? What are the (chrono-)stratigraphic challenges for better constraining glacial periods, especially during earlier periods of the Quaternary? How do climatic conditions affect glaciations and vice versa? How do Quaternary sediments compare to deposits of ice ages earlier in Earth’s history?
Repeated glaciation of an area tends to overprint older landforms and creates fragmented sedimentary successions. For the last glacial cycle, for instance, timing, extent, and driving mechanisms are increasingly well understood, whereas landscape evolution and trends in topographic preconditioning remain poorly constrained for previous glacial cycles. This complexity tends to accentuate when pre-Quaternary glaciations are considered.
We are therefore particularly interested in contributions that demonstrate how some of the limitations imposed by the geological records’ fragmentation can be overcome. For instance, by the following approaches:
1. Uncovering and characterizing glacial deposits, for example preserved in subglacially formed basins (overdeepened basins, tunnel valleys, and fjords), extend the accessible sedimentary record.
2. Modern and ancient analogues help to understand erosion and deposition mechanisms in glacial environments.
3. Relative and absolute chronostratigraphy allows the development of a temporal framework of landscape evolution and environmental conditions.
Contributions may include investigations based on field observations, scientific drilling, geophysical measurements, and/or modelling of present-day, Quaternary, and pre-Quaternary glacial settings. Possible topics cover: (a) glacial and interglacial stratigraphic successions, (b) subglacial erosion and deposition, (c) glaciation chronology, and (d) landscape evolution.

Present-day glacial and periglacial processes in cold regions, i.e. arctic and alpine environments, provide modern analogues to processes and climatic changes that took place during the Pleistocene, including gradual retreat or collapse of ice sheets and mountain glaciers, and thawing and shrinking of low-land permafrost. Current geomorphological and glaciological changes in mid-latitude mountain ranges could also serve as a proxy for future changes in high-latitude regions within a context of climate change. Examples are speed-up or disintegration of creeping permafrost features or the relictification of rock glaciers.
For our session we invite contributions that either:
1. investigate present-day glacial and/or periglacial landforms, sediments and processes to describe the current state, to reconstruct past environmental conditions and to predict future scenarios in cold regions; or
2. have a Quaternary focus and aim at enhancing our understanding of past glacial, periglacial and paraglacial processes, also through the application of dating techniques.
Case studies that use a multi-disciplinary approach (e.g. field, laboratory and modelling techniques) and/or that highlight the interaction between the glacial, periglacial and paraglacial cryospheric components in cold regions are particularly welcome.

Mountain glaciations have a long research heritage since they provide an invaluable record for past and present climate change. However, complex glaciological conditions, geomorphological processes and topography can make regional and intra-hemispheric correlations challenging. This problem is further enhanced by ongoing specialisation within the scientific community, whereby working groups often focus on individual aspects or selected mountain regions, thus frequently remain disconnected.
The main incentive for this session is to evaluate the potential of mountain glaciation records and stimulate further discussion to work towards bridging between specialised research communities. Contributions on all relevant aspects are welcomed, including (but not limited to): (a) glacial landforms and glacier reconstructions, (b) dating techniques and glacier chronologies, (c) glaciology and palaeoclimatic interpretations, (d) impacts on ecosystems and human society.
A special regional focus within the session will be dedicated to the Andean Cordillera and topics such as glaciers and palaeoclimatic records from the Andean Cordillera or model-data comparisons that aim to improve projections of future climate and ice-mass behaviour in the Andes and beyond.
Submissions involving interdisciplinary studies, complex interactions or highlighting the specific conditions of mountain glaciations, from continental to maritime regions at any latitude, are encouraged. The potential of related studies should be highlighted alongside strategies to tackle existing challenges as this will enable the session to fully address the diversity of the topic.
In past years, precursors of this session have steadily become a popular platform for everyone interested in the emerging collaborative research network, “The Legacy of Mountain Glaciations”. This network continues to grow, and we hope the 2022 session will provide an opportunity to meet and exchange new ideas and expertise.
Recent years have seen significant reductions in Arctic sea ice extent, and a redistribution of sea ice in the Antarctic. Climate projections suggest a reduction of the sea ice cover in both poles, with the Arctic becoming seasonally ice free in the latter half of this century.
The scientific community is investing considerable effort in organising our current knowledge of the physical and biogeochemical properties of sea ice, exploring poorly understood sea ice processes (e.g. MOSAiC), and forecasting future changes of the sea ice cover, such as in CMIP6.
In this session, we invite contributions regarding all aspects of sea ice science and sea ice-climate interactions, including snow and sea ice thermodynamics and dynamics, sea ice-atmosphere and sea ice-ocean interactions, sea ice biological and chemical processes, and sea ice models. A focus on emerging processes and implications is particularly welcome.

The interaction between the ocean and the cryosphere in the Southern Ocean has become a major focus in climate research. Antarctic climate change has captured public attention, which has spawned a number of research questions, such as: Is Antarctic sea ice becoming more vulnerable in a changing climate? Where and when will melting of ice shelves by warm ocean waters yield a tipping point in Antarctic climate? What role do ice-related processes play in nutrient upwelling on the continental shelf and in triggering carbon export to deep waters? Recent advances in observational technology, data coverage, and modeling provide scientists with a better understanding of the mechanisms involving ice-ocean interactions in the far South. Processes on the Antarctic continental shelf have been identified as missing links between the cryosphere, the global atmosphere and the deep open ocean that need to be captured in large-scale and global model simulations.
This session calls for studies on physical and biogeochemical interactions between ice shelves, sea ice and the ocean. The ice-covered Southern Ocean and its role in the greater Antarctic climate system are of major interest. This includes work on all scales, from local to basin-scale to circumpolar. Studies based on in-situ observations and remote sensing as well as regional to global models are welcome. We particularly invite cross-disciplinary topics involving physical and biological oceanography, glaciology or biogeochemistry.

The rapid decline of the Arctic sea ice in the last decade is a dramatic indicator of climate change. The Arctic sea ice cover is now thinner, weaker and drifts faster. Freak heatwaves are common. On land, the permafrost is dramatically thawing, glaciers are disappearing, and forest fires are raging. The ocean is also changing: the volume of freshwater stored in the Arctic has increased as have the inputs of coastal runoff from Siberia and Greenland and the exchanges with the Atlantic and Pacific Oceans. As the global surface temperature rises, the Arctic Ocean is speculated to become seasonally ice-free by the mid 21st century, which prompts us to revisit our perceptions of the Arctic system as a whole. What could the Arctic Ocean look like in the future? How are the present changes in the Arctic going to affect and be affected by the lower latitudes? What aspects of the changing Arctic should observational, remote sensing and modelling programmes address in priority?
In this session, we invite contributions from a variety of studies on the recent past, present and future Arctic. We encourage submissions examining interactions between the ocean, atmosphere and sea ice, on emerging mechanisms and feedbacks in the Arctic and on how the Arctic influences the global ocean. Submissions taking a cross-disciplinary, system approach and focussing on emerging cryospheric, oceanic and biogeochemical processes and their links with land are particularly welcome.
The session supports the actions of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030) towards addressing challenges for sustainable development in the Arctic and its diverse regions. We aim to promote discussions on the future plans for Arctic Ocean modelling and measurement strategies, and encourages submissions on the results from IPCC CMIP and the recent observational programs, such as the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC). This session is cosponsored by the CLIVAR /CliC Northern Ocean Regional Panel (NORP) that aims to facilitate progress and identify scientific opportunities in (sub)Arctic ocean-sea-ice-atmosphere research.
Drs Karen Assmann and Wilken-Jon von Appen are the solicited speakers for the session. Karen Assmann will be presenting on physical and ecological implications of Arctic Atlantification. Wilken-Jon von Appen will be talking about eddies in the Arctic Ocean.

In recent decades, the climate in the polar regions has undergone dramatic changes. Quantifying the individual contributions of Earth system components (cryosphere, ocean, atmosphere, and land) to the observed changes is challenging due to feedback between the components. Examples include (but are not limited to) ice shelf-ocean interactions (through basal melting and cavity geometry evolution) and elevation feedbacks (through surface mass balance). Hence, studies based on individual components of the Earth System have limited capacity to represent all relevant processes. This session aims to provide a platform for sharing coupled modelling experiences incorporating the cryosphere in the polar regions.
Before obtaining scientific outcomes, design decisions must be made in the development of coupled models. Adopting existing coupling technologies or implementing new, concurrent or sequential parallelism, bringing component source codes together or maintaining independence, choosing the level of temporal synchronicity between components operating on different timescales, are all examples of choices to be made.
We solicit both technical and scientific contributions from modelling studies in which feedback and emergent properties between the cryosphere and other Earth System components in polar regions are investigated, better understood, and possibly even quantified. In addition to application of coupled modelling to real world domains, contributions are also invited from idealised studies and intercomparisons, such as the Marine Ice Sheet-Ocean Intercomparison Project (MISOMIP).
The polar climate system is strongly affected by interactions between the atmosphere and the cryosphere. Processes that exchange heat, moisture and momentum between land ice, sea ice and the atmosphere play an important role in local-to-global processes. Atmosphere-ice interactions are also triggered by synoptic weather phenomena such as cold air outbreaks, polar lows, atmospheric rivers and Foehn winds. However, our understanding of these processes is still incomplete. Despite being a crucial milestone for reaching accurate projections of future climate change in Polar Regions, deciphering the interplay between the atmosphere, land ice and sea ice on different spatial and temporal scales, remains a major challenge.
This session aims at showcasing recent research progress and augmenting existing knowledge in polar meteorology and climate and the atmosphere-land ice-sea ice coupling in both the Northern and Southern Hemispheres. It will provide a setting to foster discussion and help identify gaps, tools, and studies that can be designed to address these open questions. It is also the opportunity to convey newly acquired knowledge to the community.
We invite contributions on all observational and numerical modelling aspects of Arctic and Antarctic meteorology and climatology, that address atmospheric interactions with the cryosphere. This may include but is not limited to studies on past, present and future of:
- Atmospheric processes that influence sea-ice (snow on sea ice, sea ice melt, polynya formation and sea ice production) and associated feedbacks,
- The variability of the polar large-scale atmospheric circulation (such as polar jets, the circumpolar trough and storm tracks) and impact on the cryosphere (sea ice and land ice),
- Atmosphere-ice interactions triggered by synoptic and meso-scale weather phenomena such as cold air outbreaks, katabatic winds, extratropical cyclones, polar cyclones, atmospheric rivers, Foehn winds,
- Role of clouds in polar climate and impact on the land ice and sea ice through interactions with radiation,
- Teleconnections and climate indices and their role in land ice/sea ice variability.
Presentations including new observational (ground and satellite-based) and modelling methodologies specific to polar regions are encouraged. Contributions related to results from recent field campaigns in the Arctic and in the Southern Ocean/Antarctica are also welcomed.

The Arctic Realm is changing rapidly and the fate of the cryosphere, including Arctic sea ice, glaciers and ice caps, is a source of concern. Whereas sea ice variations impact the radiative energy budget, thus playing a role in Arctic amplification, the Greenland Ice Sheet retreat contributes to global sea level rise. Moreover, through various processes linking the atmosphere, ice and ocean, the change in the Arctic realm may modify the atmospheric and ocean circulation at regional to global scales, the freshwater budget of the ocean and deep-water formation as well as the marine and terrestrial ecosystems, including productivity. The processes and feedbacks involved operate on all time scales and it require a range of types of information to understand the processes, drivers and feedbacks involved in Arctic changes, as well as the land-ocean-cryosphere interaction. In this session, we invite contributions from a range of disciplines and across time scales, including observational (satellite and instrumental) data, historical data, geological archives and proxy data, model simulations and forecasts, for the past, present and future climate. The common denominator of these studies will be their focus on a better understanding of mechanisms and feedbacks on short to long time scales that drive Arctic and subarctic changes and their impact on climate, ocean and environmental conditions, at regional to global scales, including possible links to weather and climate outside the Arctic.

Arctic sea ice and high latitude atmosphere and oceans have experienced significant changes over the modern observational era. The polar climate is crucial for the Earth’s energy and water budget, and its variability and change have direct socio-economic and ecological impacts. Thus, understanding high-latitude variability and improving predictions of high latitude climate is highly important for society. Long-term variability in ocean and sea ice are the largest sources for predictability in high latitudes. Dynamical model predictions are not yet in the position to provide us with highly accurate predictions of the polar climate. Main reasons for this are the lack of observations in high latitudes, insufficient initialization methods and shortcomings of climate models in representing some of the important climate processes in high latitudes.
This session aims for a better understanding and better representation of the mechanisms that control high latitude variability and predictability of climate in both hemispheres from sub-seasonal to multi-decadal time-scales in past, recent and future climates. Further, the session aims to discuss ongoing efforts to improve climate predictions at high latitudes at various time scales (e.g., usage of additional observations for initialization, improved initialization methods, impact of higher resolution, improved parameterizations, novel verification approaches) and potential teleconnections of high latitude climate with lower latitude climate. We also aim to link polar climate variability and predictions to potential ecological and socio-economic impacts and encourage submissions on this topic.
The session offers the possibility to present results from ongoing projects and research efforts on the topic of high-latitude climate variability and prediction, including, but not limited to, the WMO Year of Polar Prediction (YOPP), NordForsk-project ARCPATH, MOSAiC, and the H2020-projects APPLICATE, INTAROS, BlueAction, and KEPLER.
This session has greatly benefited by the expansion via added contributions from the CL4.11 session on "Arctic climate change: governing mechanisms and global implications" that specifically aims to identify, characterize and quantify the processes and feedbacks that govern amplified Arctic warming and sea ice retreat, and it also addresses the climate impacts on the lower latitudes associated with Arctic changes.

One of the big challenges in Earth system science consists in providing reliable climate predictions on sub-seasonal, seasonal, decadal and longer timescales. The resulting data have the potential to be translated into climate information leading to a better assessment of global and regional climate-related risks.
The latest developments and progress in climate forecasting on subseasonal-to-decadal and longer timescales will be discussed and evaluated. This will include presentations and discussions of predictions for the different time horizons from dynamical ensemble and statistical/empirical forecast systems, as well as the aspects required for their application: forecast quality assessment, multi-model combination, bias adjustment, downscaling, exploration of artificial-intelligence methods, etc.
Following the new WCRP strategic plan for 2019-2029, prediction enhancements are solicited from contributions embracing climate forecasting from an Earth system science perspective. This includes the study of coupled processes between atmosphere, land, ocean, and sea-ice components, as well as the impacts of coupling and feedbacks in physical, chemical, biological, and human dimensions. Contributions are also sought on initialization methods that optimally use observations from different Earth system components, on assessing and mitigating the impacts of model errors on skill, and on ensemble methods.
We also encourage contributions on the use of climate predictions for climate impact assessment, demonstrations of end-user value for climate risk applications and climate-change adaptation and the development of early warning systems.
A special focus will be put on the use of operational climate predictions (C3S, NMME, S2S), results from the CMIP5-CMIP6 decadal prediction experiments, and climate-prediction research and application projects.
An increasingly important aspect for climate forecast's applications is the use of most appropriate downscaling methods, based on dynamical or statistical approaches or their combination, that are needed to generate time series and fields with an appropriate spatial or temporal resolution. This is extensively considered in the session, which therefore brings together scientists from all geoscientific disciplines working on the prediction and application problems.

In 2015, the UN Sustainable Development Goals and the Paris Agreement on climate recognized the deteriorating resilience of the Earth system, with planetary-scale human impacts constituting a new geological epoch: the Anthropocene. Earth system resilience critically depends on the nonlinear interplay of positive and negative feedbacks of biophysical and increasingly also socio-economic processes. These include dynamics and interactions between the carbon cycle, the atmosphere, oceans, large-scale ecosystems, and the cryosphere, as well as the dynamics and perturbations associated with human activities.
With rising anthropogenic pressures, there is an increasing risk we might be hitting the ceiling of some of the self-regulating feedbacks of the Earth System, and cross tipping points which could trigger large-scale and partly irreversible impacts on the environment, and impact the livelihood of millions of people. Potential domino effects or tipping cascades could arise due to the interactions between these tipping elements and lead to a further decline of Earth resilience. At the same time, there is growing evidence supporting the potential of positive (social) tipping points that could propel rapid decarbonization and transformative change towards global sustainability.
In this session we invite contributions on all topics relating to tipping points in the Earth system, positive (social) tipping, as well as their interaction and domino effects. We are particularly interested in various methodological approaches, from Earth system modelling to conceptual modelling and data analysis of nonlinearities, tipping points and abrupt shifts in the Earth system.

The dynamics of the Earth system and its components is highly nonlinear. In particular, several subsystems have been suggested to react abruptly at critical levels of anthropogenic forcing. Well-known examples of such Tipping Elements include the Atlantic Meridional Overturning Circulation, the polar ice sheets and sea ice, tropical and boreal forests, as well as the Asian monsoon systems. Interactions between the different Tipping Elements may either have stabilizing or destabilizing effects on the other subsystems, potentially leading to cascades of abrupt transitions. The critical forcing levels at which abrupt transitions occur have recently been associated with Tipping Points.
It is paramount to determine the critical forcing levels (and the associated uncertainties) beyond which the systems in question will abruptly change their state, with potentially devastating climatic, ecological, and societal impacts. For this purpose, we need to substantially enhance our understanding of the dynamics of the Tipping Elements and their interactions, on the basis of paleoclimatic evidence, present-day observations, and models spanning the entire hierarchy of complexity. Moreover, to be able to mitigate - or prepare for - potential future transitions, early warning signals have to be identified and monitored in both observations and models.
This multidisciplinary session invites contributions that address Tipping Points in the Earth system from the different perspectives of all relevant disciplines, including
- the mathematical theory of abrupt transitions in (random) dynamical systems,
- paleoclimatic studies of past abrupt transitions,
- data-driven and process-based modelling of past and future transitions,
- early-warning signals
- the implications of abrupt transitions for Climate sensitivity and response,
- ecological and societal impacts, as well as
- decision theory in the presence of uncertain Tipping Point estimates

To address societal concerns over rising sea level and extreme events, understanding the contributions behind these changes is key to predict potential impacts of sea level change on coastal communities and global economy, and is recognized as one of the Grand Challenges of our time by the World Climate Research Programme (WCRP). To continue this discussion, we welcome contributions from the international sea level community that improve our knowledge of the past and present changes in global and regional sea level, extreme events, and flooding, and produce improved predictions of their future changes.
We welcome studies on various drivers of sea level change and linkages between variability in sea level, heat and freshwater content, ocean dynamics, land subsidence from natural versus anthropogenic influences, and mass exchange between the land and the ocean associated with ice sheet and glacier mass loss and changes in the terrestrial water storage. Studies focusing on future sea level changes are also encouraged, as well as those discussing potential short-, medium-, and long-term impacts on coastal and deltaic environments, as well as the global oceans.

Publishing your research in a peer reviewed journal is essential for a career in research. All EGU-affiliated journals are fully open access which is great, but the unique open discussion and transparent peer review process can be daunting for first time submitters and early career scientists. This short course will cover all you need to know about the publication process from start to end for EGU journals, and give you a chance to ask the editors some questions. This includes: what the editor looks for in your submitted paper, how to deal with corrections or rejections, and how best to communicate with your reviewers and editors for a smooth transition from submission to publication. Ample time will be reserved for open discussion for the audience to ask questions to the editors, and for the editors to suggest ‘top tips’ for successful publication. This course is aimed at early-career researchers who are about to step into the publication process, and those who are yet to publish in EGU journals. Similarly, this course will be of interest to those looking to get involved in the peer-review process through reviewing and editing. This short course is part of the “Meet the EGU Journal Editors” webinar series that was held prior to the EGU General Assembly 2022.
Public information:
We are excited to welcome our panelists for this session, who will be representing their respective journals:
On 9 August 2021, the Intergovernmental Panel on Climate Change (IPCC) released the first volume of its 6th Assessment Report (AR6). The Working Group I contribution to the Report (Climate Change 2021: The Physical Science Basis) synthesises over 14,000 publications and represents the most comprehensive and up-to-date assessment of the climate system and climate change. Crucially, the Report highlights the unprecedented and potentially irreversible influence of anthropogenic climate forcing, and for the first time, explicitly states that human influence on the climate system is unequivocal.
This short course will be a panel discussion where authors and contributors of Working Group I unpack how the IPCC 6th Assessment Report (AR6) is produced, provide personal behind-the-scenes insight on its development, and discuss its global impact, including how it is used to inform policy. Authors of the report will share their experiences of working on the report before and through the COVID pandemic. Panelists will also emphasise various ways in which scientists of all career stages can contribute to the IPCC process. Ample time will be allocated for open discussion for the audience to ask related questions to the panelists.
For more information about the AR6 please visit the IPCC website: https://www.ipcc.ch/.
We have developed an open source software package in python for ground-based GNSS reflections – gnssrefl (https://github.com/kristinemlarson/gnssrefl). This new software supports geoscientists wishing to measure in situ snow accumulation, permafrost melt, firn density, tides, and lake/river levels. We have developed videos (hosted on youtube) to help new users understand both the basic concepts of GNSS reflections and how to install and run the gnssrefl code. More than a dozen use cases are available online; Jupyter Notebooks have been developed as well. We envision the EGU tutorial session to be hands-on and interactive, with a focus on demonstrating the gnssrefl software and online tools (https://gnss-reflections.org), examining and discussing environmental results derived from GNSS data taken from public archives, and analyzing new datasets suggested by the students.
Public information:
We have developed an open source code in python (gnssrefl) that allows users to measure either water levels or snow accumulation using GNSS data. This session will be devoted to helping users understand how to run and install the code. Please see the github (https://github.com/kristinemlarson/gnssrefl) repository for some tips on how to install the gnssrefl package on your local machine. We currently support the python code on linux and macs, with docker images for these and PCs. We also have links to jupyter notebooks. There is a complementary web app at https://gnss-reflections.org.
QuakeMigrate is a new, open-source software package for automatic earthquake detection and location (https://github.com/QuakeMigrate/QuakeMigrate). Our software provides a means for seismologists to extract highly complete catalogues of microseismicity from continuous seismic data, whether their network is installed at a volcano, plate-boundary fault zone, on an ice shelf, or even on another planet. Rather than traditional pick-based techniques, it uses a migration-based approach to combine the recordings from stations across a seismic network, promising increased robustness to noise, more accurate hypocentre locations, and improved detection capability. Cloud-hosted Jupyter Notebooks and tutorials (https://mybinder.org/v2/gh/QuakeMigrate/QuakeMigrate/master) provide an overview of the philosophy and capabilities of our algorithm, and in this session we intend to provide a more hands-on introduction, with a focus on providing a general understanding of the considerations when applying a waveform-based algorithm to detect and locate seismicity.
QuakeMigrate has been constructed with a modular architecture, to make it flexible to use in different settings. We will demonstrate its use in detecting and locating basal icequakes at the Rutford Ice Stream, Antarctica, volcano-tectonic seismicity during the 2014 Bárðarbunga-Holuhraun and 2021 Reykjanes/Fagradalsfjall dike intrusions, and aftershocks from a M5 tectonic earthquake in northern Borneo, which was recorded on a sparse regional seismic network. In each case we will discuss the reasoning behind parameter selections, and the key factors in maximising detection sensitivity while minimising computational cost. We will end the session by exploring sample datasets provided by attendees, with interactive involvement as we tune parameters and use the comprehensive array of automatically generated plots to take a preliminary look at unseen data.

What is the “Potsdam Gravity Potato”? What is a reference frame and why is it necessary to know in which reference frame GNSS velocities are provided? Geodetic data, like GNSS data or gravity data, are used in many geoscientific disciplines, such as hydrology, glaciology, geodynamics, oceanography and seismology. This course aims to give an introduction into geodetic datasets and presents what is necessary to consider when using such data. This 105-minute short course is part of the quartet of introductory 101 courses on Geodynamics 101, Geology 101 and Seismology 101.
The short course Geodesy 101 will introduce basic geodetic concepts within the areas of GNSS and gravity data analysis. In particular, we will talk about:
- GNSS data analysis
- Reference frames
- Gravity data analysis
We will also show short examples of data handling and processing using open-source software tools. Participants are not required to bring a laptop or have any previous knowledge of geodetic data analysis.
Our aim is to give you more background information on what geodetic data can tell us and what not. You won’t be a Geodesist by the end of the short course, but we hope that you are able to have gained more knowledge about the limitations as well as advantages of geodetic data. The course is run by early career scientists from the Geodesy division, and is aimed for all attendees (ECS and non-ECS) from all divisions who are using geodetic data frequently or are just interested to know what geodesists work on on a daily basis. We hope to have a lively discussion during the short course and we are also looking forward to feedback by non-geodesists on what they need to know when they use geodetic data.

Faults and fracture zones are fundamental features of geological reservoirs that control the physical properties of the rock. As such, understanding their role in in-situ fluid behaviour and fluid-rock interactions can generate considerable advantages during exploration and management of reservoirs and repositories.
Physical properties such as frictional strength, cohesion and permeability of the rock impact deformation processes, rock failure and fault/fracture (re-)activation. Faults and fractures create fluid pathways for fluid flow and allow for increased fluid-rock interaction.
The presence of fluids circulating within a fault or fracture network can expose the host rocks to significant alterations of the mechanical and transport properties. This in turn can either increase or decrease the transmissibility of a fracture network, which has implications on the viability and suitability of subsurface energy and storage projects. Thus, it is important to understand how fluid-rock interactions within faults and fractures may alter the physical properties of the system during the operation of such projects. This is of particular interest in the case of faults as the injection/ remobilisation of fluids may affect fault/fracture stability, and therefore increase the risk of induced seismicity and leakage.
Fieldwork observations, monitoring and laboratory measurements foster fundamental understanding of relevant properties, parameters and processes, which provide important inputs to numerical models (see session “Faults and fractures in geoenergy applications 1: Numerical modelling and simulation”) in order to simulate processes or upscale to the reservoir scale. A predictive knowledge of fault zone structures and transmissibility can have an enormous impact on the viability of geothermal, carbon capture, energy and waste storage projects.
We encourage researchers on applied or interdisciplinary energy studies associated with low carbon technologies to come forward for this session. We look forward to interdisciplinary studies which use a combination of methods to analyse rock deformation processes and the role of faults and fractures in subsurface energy systems, including but not restricted to outcrop studies, monitoring studies, subsurface data analysis and laboratory measurements. We are also interested in research across several different scales and addressing the knowledge gap between laboratory scale measurements and reservoir scale processes.
Geological and geophysical data sets are in essence the result of physical processes governing the Earth’s evolution. Such data sets are widely varied and range from the internal structure of the Earth, plate kinematics, composition of geomaterials, estimation of physical conditions, dating of key geological events, thermal state of the Earth to more shallow processes such as natural and “engineered” reservoir dynamics and waste sequestration in the subsurface.
Combining such data with process-based numerical models is required for our understanding of the dynamical Earth. Process-based models are powerful tools to predict the evolution of complex natural systems resolving the feedback among various physical processes. Integrating high-quality data into numerical simulations leads to a constructive workflow to further constrain the key parameters within the models. Innovative inversion strategies, linking forward dynamic models with observables, is therefore an important research topic that will improve our knowledge of the governing physical parameters.
The complexity of geological systems arises from their multi-physics nature, as they combine hydrological, thermal, chemical and mechanical processes (e.g. thermo-mechanical convection). Multi-physics couplings are prone to nonlinear interactions ultimately leading to spontaneous localisation of flow and deformation. Understanding the couplings among those processes therefore requires the development of appropriate tools to capture spontaneous localisation and represents a challenging though essential research direction.
We invite contributions from the following two complementary themes:
1. Computational advances associated with
- alternative spatial and/or temporal discretisation for existing forward/inverse models
- scalable HPC implementations of new and existing methodologies (GPUs / multi-core)
- solver and preconditioner developments
- AI / Machine learning-based approaches
- code and methodology comparisons (“benchmarks”)
- open source implementations for the community
2. Physics advances associated with
- development of partial differential equations to describe geological processes
- inversion strategies and adjoint-based modelling
- numerical model validation through comparison with observables (data)
- scientific discovery enabled by 2D and 3D modelling
- utilisation of coupled models to explore nonlinear interactions

Many regions of the Earth, from crust to core, exhibit anisotropic fabrics which can reveal much about geodynamic processes in the subsurface. These fabrics can exist at a variety of scales, from crystallographic orientations to regional structure alignments. In the past few decades, a tremendous body of multidisciplinary research has been dedicated to characterizing anisotropy in the solid Earth and understanding its geodynamical implications. This has included work in fields such as: (1) geophysics, to make in situ observations and construct models of anisotropic properties at a range of depths; (2) mineral physics, to explain the cause of some of these observations; and (3) numerical modelling, to relate the inferred fabrics to regional stress and flow regimes and, thus, geodynamic processes in the Earth. The study of anisotropy in the Solid Earth encompasses topics so diverse that it often appears fragmented according to regions of interest, e.g., the upper or lower crust, oceanic lithosphere, continental lithosphere, cratons, subduction zones, D'', or the inner core. The aim of this session is to bring together scientists working on different aspects of anisotropy to provide a comprehensive overview of the field. We encourage contributions from all disciplines of the earth sciences (including mineral physics, seismology, magnetotellurics, geodynamic modelling) focused on anisotropy at all scales and depths within the Earth.
Geomechanics has been demonstrated over the past 30 years as having key importance for the safe and sustainable usage of underground environments. In particular, knowledge of geomechanics is critical for exploration and production of geothermal energy, groundwater, hydrocarbon, and mineral resources. Geomechanics play the central role in any underground storage (such as natural gas, CO2 and H2) and disposal of nuclear or toxic waste. The main goal of this session is therefore to bring together researchers from various engineering and geo-disciplines to share their knowledge in recent advancements in experimental, numerical, theoretical and field application of geomechanics. A particular focus is on the large uncertainties that are often associated with geomechanical measurements or models. In addition to abstracts that exclusively aim at uncertainty quantification and/or reduction at least a discussion of uncertainties is encouraged in every abstract.

Understanding the current and past state of stress is key to comprehend the rheological behavior of the crust, with numerous implications spanning from geodynamics to microstructure developments, and applications spanning from seismogenesis to resource distribution. The current state of stress is mainly assessed on seismic focal mechanisms, fault monitoring and slip inversion, borehole failure and imaging, and methods such as hydraulic fracturing to determine the magnitude of the applied stress. Paleopiezometry techniques rely on experimental and/or analytical approaches that link a finite deformation to an applied stress magnitude. Such technique allows to reconstruct past stress magnitude, orientation and regime on long time-scales. This session aims at picturing the state-of-the-art of the stress determination in the crust, whether it is the current stress or the past stress. We welcome any contribution that reconstructs regional state of stress in the crust by the mean of current measurement or paleopiezometry techniques, and that uses experimental or analytical/numerical approaches to predict stress distribution in rocks.

Processes controlling the global cycles of volatiles (e.g., C, H, O, S) across reservoirs regulate planetary climate and habitability. Their cycling pathways and efficiency are dependent on numerous factors including the presence of liquid water and the tectonic mode; and involves the atmosphere, hydrosphere, crust, mantle and even the core.
On Earth, major volatile cycles are balanced to first order through ingassing and outgassing, mainly occurring at subduction zones, and major sites of volcanism (i.e., mid-ocean ridges and hotspots), respectively. In planetary interiors, volatiles are partitioned into the existing minerals, or stabilize minor phases such as diamond or various hydrous phases in the mantle and crust, something that directly influences the spatial distribution of melt formation as well as rock properties. Conversely, melt transport induces volatile exchanges between planetary reservoirs and favours outgassing. Outgassing, in turn, will regulate planetary climates, hence influencing the habitability.
The aim of this session is to bring together numerical, experimental and observational expertise from Earth and Planetary Sciences to advance the understanding of interior-atmosphere coupling and volatile exchange and evolution on Earth and terrestrial (exo)planets, as well as the role of those volatiles on the interior composition and dynamics. This session features contributions on topics including volatile cycling, melt and volatile transport, mineral-melt phase relations, geophysical detections, tectonic regimes, outgassing, atmospheric composition and planetary habitability.
From the real-time integration of multi-parametric observations is expected the major contribution to the development of operational t-DASH systems suitable for supporting decision makers with continuously updated seismic hazard scenarios. A very preliminary step in this direction is the identification of those parameters (seismological, chemical, physical, biological, etc.) whose space-time dynamics and/or anomalous variability can be, to some extent, associated with the complex process of preparation of major earthquakes.
This session wants then to encourage studies devoted to demonstrate the added value of the introduction of specific, observations and/or data analysis methods within the t-DASH and StEF perspectives. Therefore, studies based on long-term data analyses, including different conditions of seismic activity, are particularly encouraged. Similarly welcome will be the presentation of infrastructures devoted to maintain and further develop our present observational capabilities of earthquake related phenomena also contributing in this way to build a global multi-parametric Earthquakes Observing System (EQuOS) to complement the existing GEOSS initiative.
To this aim this session is not addressed just to seismology and natural hazards scientists but also to geologist, atmospheric sciences and electromagnetism researchers, whose collaboration is particular important for fully understand mechanisms of earthquake preparation and their possible relation with other measurable quantities. For this reason, all contributions devoted to the description of genetic models of earthquake’s precursory phenomena are equally welcome.

Rockfalls, rockslides and rock avalanches are among the primary hazards and drivers of landscape evolution in steep terrain. The physics of rock slope degradation and dynamics of failure and transport mechanisms define the hazards and possible mitigation strategies and enable retrodictions and predictions of events and controls.
This session aims to bring together state-of-the-art methods for predicting, assessing, quantifying, and protecting against rock slope hazards across spatial and temporal scales. We seek innovative contributions from investigators dealing with all stages of rock slope hazards, from weathering and/or damage accumulation, through detachment, transport and deposition, and finally to the development of protection and mitigation measures. In particular, we seek studies presenting new theoretical, numerical or probabilistic modelling approaches, novel data sets derived from laboratory, in situ, or remote sensing applications, and state-of-the-art approaches to social, structural, or natural protection measures. We especially encourage contributions from geomechanics/rock physics, geodynamics, geomorphology and tectonics to better understand how rockfall, rockslides and rock avalanches act across scales.

Numerous cases of induced/triggered seismicity associated with anthropogenic activity resulting either directly or indirectly from injection/extraction related to geo-resources exploration have been reported in the last decades. Induced earthquakes felt by the general public can often negatively affect public perception of geo-energies and may hinder future geo-energy development. Furthermore, large earthquakes may jeopardize wellbore stability and damage surface infrastructure. Thus, monitoring and modeling processes leading to fault slip, either seismic or aseismic, are critical to developing effective and reliable forecasting methodologies during deep underground exploitation. The complex interaction between injected fluids, subsurface geology, stress interactions, and resulting fault slip requires an interdisciplinary approach to understand the triggering mechanisms and may require taking coupled thermo-hydro-mechanical-chemical processes into account.
In this session, we invite contributions from research aimed at investigating the interaction of the above processes during exploitation of underground resources, including hydrocarbon extraction, wastewater disposal, geothermal energy exploitation, hydraulic fracturing, gas storage and production, mining, and reservoir impoundment for hydro-energy. We particularly encourage novel contributions based on laboratory and underground near-fault experiments, numerical modeling, the spatio-temporal relationship between seismic properties, injection/extraction parameters, and/or geology, and fieldwork. Contributions covering both theoretical and experimental aspects of induced and triggered seismicity at multiple spatial and temporal scales are welcome.

Geological media are a strategic resource for the forthcoming energy transition and constitute an important ally in the fight to mitigate the adverse effects of climate change. Several energy and environmental processes in the subsurface involve multi-physical interactions between the porous and fractured rock, and the fluids filling the voids: changes in pore pressure and temperature, rock deformation and chemical reactions occur simultaneously and impact each other. This characteristic has profound implications on the energy production and the waste storage. Forecasts are bounded to the adequate understanding of field data associated with thermo-hydro-mechanical-chemical (THMC) processes and predictive capabilities heavily rely on the quality of the integration between the input data (laboratory and field evidence) and the mathematical models describing the evolution of the multi-physical systems. This session is dedicated to studies investigating THMC problems by means of experimental, analytical, numerical, multi-scale, data-driven and artificial intelligence methods, as well as studies focused on laboratory characterization and on gathering and interpreting in-situ geological and geophysical evidence of the multi-physical behavior of rocks. Welcomed contributions include approaches covering applications of carbon capture and storage (CCS), geothermal systems, gas storage, energy storage, mining, reservoir management, reservoir stimulation, fluid injection-induced seismicity and radioactive waste storage.

Rock deformation at different stress levels in the brittle regime and across the brittle-ductile transition is controlled by damage processes occurring on different spatial scales, from grain scale to fractured rock masse. These lead to a progressive increase of micro- and meso-crack intensity in the rock matrix and to the growth of inherited macro-fractures at rock mass scale. Coalescence of these fractures forms large-scale structures such as brittle fault zones and deep-seated rock slide shear zones. Diffuse or localized rock damage have a primary influence on rock properties (strength, elastic moduli, hydraulic and electric properties) and their evolution across multiple temporal scales spanning from geological times to highly dynamic phenomena as earthquakes, volcanic eruptions and landslides. In subcritical stress conditions, damage accumulation results in brittle creep processes key to the long-term evolution of geophysical, geomorphological and geo-engineering systems.
Damage and progressive failure processes must be considered to understand the time-dependent hydro-mechanical behaviour of faults (e.g. stick-slip vs aseismic creep), volcanic systems and slopes (e.g. slow rock slope deformation vs catastrophic rock slides), as well as the response of rock masses to stress perturbations induced by artificial excavations (tunnels, mines) and static or dynamic loadings. At the same time, damage processes control the brittle behaviour of the upper crust and are strongly influenced by intrinsic rock properties (strength, fabric, porosity, anisotropy), geological structures and their inherited damage, as well as by the evolving pressure-temperature with increasing depth and by fluid pressure, transport properties and chemistry. However, many complex relationships between these factors and rock damage are yet to be understood.
In this session we will bring together researchers from different communities interested in a better understanding of rock damage processes and consequence. We welcome innovative contributions on experimental studies (both in the laboratory and in situ), continuum / micromechanical analytical and numerical modelling, and applications to fault zones, reservoirs, slope instability and landscape evolution, and engineering applications. Studies adopting novel approaches and combined methodologies are particularly welcome.
Geophysical methods have a great potential for characterizing subsurface properties and processes to inform geological, reservoir, hydrological, and biogeochemical studies. In these contexts, the classically used geophysical tools only provide indirect information about subsurface heterogeneities, reservoir rocks characteristics, and associated processes (e.g. flow, transport, biogeochemical reactions). Petrophysical relationships hence have to be developed to provide links between physical properties (e.g. electrical conductivity, seismic velocity or attenuation) and the intrinsic parameters of interest (e.g. fluid content, hydraulic properties, pressure conditions). In addition, geophysical methods are increasingly deployed as time-lapse, or even continuous, and distributed monitoring tools on more and more complex environments. Here again, there is a great need for accurate and efficient physical relationships such that geophysical data can be correctly interpreted (e.g. included in fully coupled inversions).
Establishing such models requires multidisciplinary approaches since involved theoretical frameworks differ. Each physical property has its intrinsic dependence to pore-scale interfacial, geometrical, and biogeochemical properties or to external condition (such as pressure or temperature). Each associated geophysical method has its specific investigation depth and spatial resolution which adds a significant level of complexity in combining and scaling theoretical developments with laboratory studies/validations and/or with field experiments. Ultimately, as inferred from geophysics, one needs to know the poroelastic properties and effective stress in place at depth.
This session consequently invites contributions from various communities to share their models, their experiments, or their field tests and data in order to discuss about multidisciplinary ways to improve our knowledge on reservoir and near surface environment.

This session aims to discuss recent advances in our understanding of the mechanical, structural, and seismic properties of the lower crust and upper mantle. Earth’s lithosphere is defined by its rheological and mechanical stability. Both shear localization and seismic instabilities are frequently observed through regional seismicity, laboratory experiments, numerical models,, and field observations, e.g., pseudotachylyte-bearing faults. In contrast to the shallow crust, dominated by brittle deformation, localized faulting, and frictional sliding, deformation observed in the mid- to lower- crust and upper mantle often displays localized faulting alongside more distributed flow and evidence for a variable mix of brittle and plastic deformation mechanisms. Because brittle and plastic deformation take place simultaneously over different time scales, the interplay between them is complex, and the resulting semi-brittle deformation style is still poorly understood. However, numerous enigmatic deformation phenomena, including slow-slip and lower crustal earthquakes, coincide with depths that either fall within, or mark the boundaries of, the semi-brittle field -- the brittle to ductile and the ductile to plastic transitions. We encourage geoscientists from across experimental geophysics, structural geology, seismology, and geodynamics with an interest in the interplay between different deformation mechanisms to contribute to this session.

The integrated analysis and inversion of multiple types of geophysical data has become increasingly popular in recent years. This is largely due to its proven ability to reduce uncertainty in subsurface characterisation. These multiphysics studies often analyse seismic and controlled source electromagnetic data simultaneously, but the inclusion of geological, petrological, magnetic, or gravity measurements is also not uncommon.
On the lithospheric scale, multiphysics inversion has applications in estimating the composition of the Earth’s crustal and upper mantle, while on the reservoir scale, its proven and potential applications lie in characterising hydrocarbon, CO2, groundwater and hydrothermal reservoirs. On a more localised scale, its uses range from mineral mapping to geotechnical studies for windfarm development, and on the core scale, cross-property modelling and experimentation is continually advancing our understanding of the relationships linking a rock’s various physical properties as a function of pressure.
This session invites contributions on the topics of multiphysics, joint rock physics and geophysical inversion, and cross-property modelling. Field applications, experimental studies, modelling, and theoretical advances are especially welcome.

The dynamics and evolution of Earth’s surface and interior are controlled by a spectrum of processes covering a wide range of length (i.e. from kilometers down to a few ångströms) and time scales (i.e. from billions of years down to picoseconds). Microstructures in planetary materials (e.g., fabrics, textures, grain sizes and distributions, shapes, cracks etc) can be used to infer, identify, and quantify metamorphic, magmatic or diagenetic processes. Coupling these microscale processes with larger scale, planetary phenomena (e.g. formation of plate boundaries or mantle convection) remains one of the key challenges in solid Earth geosciences. Fundamentally, processes such as grain size reduction, grain growth, phase changes, and the development of crystallographic preferred orientations modify the rheological properties of rocks and minerals, providing key information on the dynamics of small- to large-scale geodynamic processes. In this session, we invite contributions investigating microstructures and textures in field samples, laboratory experiments, and numerical modeling with the aim to constrain deformation processes of Earth’s surface and interior across multiple length scales.

Understanding the structures and dynamics of the core of a planet is essential to construct a global geochemical and geodynamical model, it has implication on its thermal, compositional and orbital evolution.
Remote sensing of planets interior from space and ground-based observations is entering a new era with perspectives in constraining their core structures and dynamics. Meanwhile, increasingly accurate seismic and magnetic data provides unprecedented images of the Earth's deep interior. Unraveling planetary cores structures and dynamics requires a synergy between many fields of expertise, such as mineral physics, geochemistry, seismology, fluid mechanics or geomagnetism. In such a cross-disciplinary context, we identify the need to combine observations, e.g. from geo/paleo/rock magnetism, to generate field models and carefully compare their properties with numerical simulations of the dynamo process. This requires community-wide efforts to share data and models in standardized formats, which we aim to address.
This session welcomes contributions from all the disciplines mentioned following theoretical, numerical, observational or experimental approaches, with the aim to proceed towards an integrated, self-consistent picture of planetary core's structure, dynamics, magnetic field and their evolution.
Long term observations are of vital importance in the Earth Sciences, yet often difficult to pursue and fund. The distinction of a fluctuation from a long-term change in Earth processes is a key question to better understand processes within the Earth and in the Earth system. Likewise, it is a prerequisite for the assessment of the Earth's climate change as well as risk assessment. In order to distinguish fluctuations from a steady change, knowledge on the time variability of the signal itself and long term observations are required. Exemplarily, due to the decadal variability of sea level, reliable sea level trends can only be obtained after about sixty years of continuous observations. Reliable strain rates of deformation require a minimum of a decade of continuous data, due to ambient and anthropogenic factors leading to fluctuations. This session invites contributions demonstrating the importance of long term geophysical, geodynamic, oceanographic, geodetic, and climate observatories. Advances in sensors, instrumentation, monitoring techniques, analyses, and interpretations of data, or the comparison of approaches are welcome, with the aim to stimulate a multidisciplinary discussion among those dedicated to the accumulation, preservation and dissemination of data over decadal time scales or beyond. Studies utilizing novel approaches such as AI for analysis of long time series are very welcome. Likewise, studies that show the mutual transfer of knowledge of terrestrial and satellite observations are a topic of interest. With this session, we also would like to provide an opportunity to gather and exchange experiences for representatives from observatories both in Europe and worldwide.
Non-destructive testing (NDT) methods are employed in a variety of engineering and geosciences applications and their stand-alone use has been greatly investigated to date. New theoretical developments, technological advances and the progress achieved in surveying, data processing and interpretation have in fact led to a tremendous growth of the equipment reliability, allowing outstanding data quality and accuracy.
Nevertheless, the requirements of comprehensive site and material investigations may be complex and time-consuming, involving multiple expertise and multiple equipment. The challenge is to step forward and provide an effective integration between data outputs with different physical quantities, scale domains and resolutions. In this regard, enormous development opportunities relating to data fusion, integration and correlation between different NDT methods and theories are to be further investigated.
This Session primarily aims at disseminating contributions from state-of-the-art NDT methods and new numerical developments, promoting the integration of existing equipment and the development of new algorithms, surveying techniques, methods and prototypes for effective monitoring and diagnostics. NDT techniques of interest are related–but not limited to–the application of acoustic emission (AE) testing, electromagnetic testing (ET), ground penetrating radar (GPR), geoelectric methods (GM), laser testing methods (LM), magnetic flux leakage (MFL), microwave testing, magnetic particle testing (MT), neutron radiographic testing (NR), radiographic testing (RT), thermal/infrared testing (IRT), ultrasonic testing (UT), seismic methods (SM), vibration analysis (VA), visual and optical testing (VT/OT).
The Session will focus on the application of different NDT methods and theories and will be related –but not limited to– the following investigation areas:
- advanced data fusion;
- advanced interpretation methods;
- design and development of new surveying equipment and prototypes;
- real-time and remote assessment and monitoring methods for material and site inspection (real-life and virtual reality);
- comprehensive and inclusive information data systems for the investigation of survey sites and materials;
- numerical simulation and modelling of data outputs with different physical quantities, scale domains and resolutions;
- advances in NDT methods, numerical developments and applications (stand-alone use of existing and state-of-the-art NDTs).
This interdisciplinary session welcomes contributions on novel conceptual and/or methodological approaches and methods for the analysis and statistical-dynamical modeling of observational as well as model time series from all geoscientific disciplines.
Methods to be discussed include, but are not limited to linear and nonlinear methods of time series analysis. time-frequency methods, statistical inference for nonlinear time series, including empirical inference of causal linkages from multivariate data, nonlinear statistical decomposition and related techniques for multivariate and spatio-temporal data, nonlinear correlation analysis and synchronisation, surrogate data techniques, filtering approaches and nonlinear methods of noise reduction, artificial intelligence and machine learning based analysis and prediction for univariate and multivariate time series.
Contributions on methodological developments and applications to problems across all geoscientific disciplines are equally encouraged. We particularly aim at fostering a transfer of new methodological data analysis and modeling concepts among different fields of the geosciences.

Gravity and magnetic field data contribute to a wide range of geo-scientific research, from imaging the structure of the earth and geodynamic processes near surface investigations. The first part of this session is dedicated to contributions related to spatial and temporal variations of the Earth gravity and magnetic field at all scales. Contributions to modern potential field research are welcome, including instrumental issues, data processing techniques, machine learning, interpretation methods, innovative applications of the results and data collected by modern satellite missions, potential theory, as well as case histories.
The second part of this session will focus on the practical solution of various formulations of geodetic boundary-value problems to yield precise local and regional high-resolution (quasi)geoid models. Contributions describing recent developments in theory, processing methods, downward continuation of satellite and airborne data, treatment of altimetry and shipborne data, terrain modeling, software development and the combination of gravity data with other signals of the gravity field for a precise local and regional gravity field determination are welcome. Topics such as the comparison of methods and results, the interpretation of residuals as well as geoid applications to satellite altimetry, oceanography, vertical datums and local and regional geospatial height registration are of a special interest.
Active and passive seismological methods are largely employed for characterizing the crustal structure in tectonic or volcanic settings, from the near-surface down to several kilometers of depth and at a global scale.
Active seismic methods (mainly reflection and refraction seismic) have shown to be particularly effective in providing images of the crust, in terms of velocities, seismic tomography, reflection coefficient, and seismic attributes. Although they are commonly used for mineral prospecting purposes, these techniques also provide a fundamental tool for studying the structural and stratigraphic patterns in different geological settings. Nonetheless, active seismic methods show several issues and limitations, mainly due to the cost and availability of the instruments, the difficulties in exploring remote areas, and the loss in resolution with depth.
In this perspective, a fruitful synergy can arise from the combination of active and passive seismic methods, which use earthquakes or ambient noise as a source. For instance, passive seismic is fundamental to detect seismogenic crustal regions, and their attitude to release seismic energy with frequent low-energy earthquakes or few strong events, by studying the b-value of the Gutenberg & Richter Frequency-Magnitude Distribution. Such information could be compared to some extent with the seismo-stratigraphic and structural model inferred from the analysis of active seismic data, for a deeper understanding of the crustal structure.
As a final issue, other geophysical data (e.g. gravimetric, magnetic, or geo-electric) could also provide further useful information, to better constrain the interpretation of seismological data.
Contributions to the session may include challenging applications, where the joint inversion and interpretation of both active and passive seismic data, corroborated by the results deriving from other methodologies, are employed to shed light on not-straightforward complexities in different geological contexts.
The never-ending growth of the ground penetrating radar applications reserves continuously small and less small discoveries, and deserves a space for discussion and reciprocal listening also at the EGU conference.
The pandemic has meaningfully hindered many activities but to our knowledge not too much the interest in the GPR instrumentation and technique at an applicative level, even if exchanges of experiences at international conferences have been of course necessarily reduced. So, we hope that this session can meet the interest of many researchers, professionals, PhD students as well skilled GPR users as geologists, engineers, geophysicists and possibly archaeologists and architects.
Contributions are welcome with regard to all the aspects of the GPR technique, ranging from the hardware of the systems to the data processing and any theoretical aspect, including innovative applications or procedures as well as results of particular relevance, possibly achieved within an integrated measurement campaign including also different data.
Hope to see you in Vienna.

The analysis of the Earth's gravity and magnetic fields is becoming increasingly important in geosciences. Modern satellite missions are continuing to provide data with ever improving accuracy and nearly global, time-dependent coverage. The gravitational field plays an important role in climate research, as a record of and reference for the observation of mass transport. The study of the Earth's magnetic field and its temporal variations is yielding new insights into the behavior of its internal and external sources. Both gravity and magnetic data furthermore constitute primary sources of information also for the global characterization of other planets. Hence, there continues to be a need to develop new methods of analysis, at the global and local scales, and especially on their interface. For over two decades now, methods that combine global with local sensitivity, often in a multiresolution setting, have been developed: these include wavelets, radial basis functions, Slepian functions, splines, spherical cap harmonics, etc. One purpose of this session is to provide a forum for exchange of research projects, whether related to forward or inverse modeling, theoretical, computational, or observational studies.
Besides monitoring the variations of the gravity and magnetic fields, space geodetic techniques deliver time series describing changes of the surface geometry, sea level change variations or fluctuations in the Earth's orientation. However, geodetic observation systems usually measure the integral effect. Thus, analysis methods have to be applied to the geodetic time series for a better understanding of the relations between and within the components of the system Earth. The combination of data from various space geodetic and remote sensing techniques may allow for separating the integral measurements into individual contributions of the Earth system components. Presentations to time frequency analysis, to the detection of features of the temporal or spatial variability of signals existing in geodetic data and in geophysical models, as well as to the investigations on signal separation techniques, e.g. EOF, are highly appreciated. We further solicit papers on different prediction techniques e.g. least-squares, neural networks, Kalman filter or uni- or multivariate autoregressive methods to forecast Earth Orientation Parameters, which are needed for real-time transformation between celestial and terrestrial reference frames.

Observations and measurements of geophysical systems and dynamical phenomena are obtained as time series or spatio-temporal data whose dynamics usually manifests a nonlinear multiscale (in terms of time and space) behavior. During the past decades, nonlinear approaches in geosciences have rapidly developed to gain novel insights on weather and climate dynamics, fluid dynamics, on turbulence and stochastic behaviors, on the development of chaos in dynamical systems, and on concepts of networks, nowadays frequently employed in geosciences.
In this short course, we will offer a broad overview of the development and application of nonlinear concepts across the geosciences in terms of recent successful applications from various fields, ranging from climate to near-Earth space physics. The focus will be on a comparison between different methods to investigate various aspects of both known and unknown physical processes, moving from past accomplishments to future challenges.

Geomagnetically Induced Currents (GICs) can damage grounded infrastructure such as high voltage transformers, gas pipelines and rail networks. Understanding their impact is vital for protecting critical national infrastructure from harm and reducing any economic consequences. GICs are caused by geoelectric fields induced in the resistive subsurface during periods of rapid change of the magnetic field, typically in geomagnetic storms; however, an increasing body of evidence shows they occur in nominally quiet times too. We seek contributions from studies that measure (directly or indirectly) or model GICs in grounded infrastructure to assess the potential hazard and vulnerability of the infrastructure and to produce reliable models with which to forecast the potential effects of severe space weather events.

It is well known that solar activity influences the state of the circumterrestrial space and can affect technological systems in many different ways and with different degrees of damage severity.
Geomagnetic data, both from ground-based observatories and low Earth orbit satellites, represent a powerful tool to monitor space weather events, such as magnetic storms, substorms and geomagnetically induced currents.
Geomagnetic field monitoring makes it possible to improve internal geomagnetic field models and gain better knowledge on the dynamics of solar-terrestrial events and ionospheric and magnetospheric geomagnetic sources (both internal and external). Furthermore, geomagnetic field data provide proxies to nowcast and forecast different ground effects due to space weather events.
In this session we therefore encourage submissions focussing on the use of geomagnetic data (from ground observatories to satellites such as CHAMP, Swarm, CSES, ePOP and others) as a tool to gain insight both into the physics of the processes involving the Earth's magnetic field in response to space weather events and into their effects as the degradation of satellite signal, perturbation in radio communications, disruption of power system devices, just as some known examples.

This session asks for contributions in the field of electromagnetic (EM) geophysical methods that are applied on various scales ranging from the near-surface to the deep mantle. This includes new instrumentation and data acquisition methods, as well as mathematical and numerical improvements to data processing, modelling, and inversion applied to ground-based and off-shore measurements, airborne and satellite missions. We are interested in studies of EM applied to global induction, imaging regional scale tectonic, magmatic, or volcanic systems, in the search for hydrocarbon, geothermal, or mineral resources, and the investigation of near surface structure relevant to environmental, urban, and hydrological systems. Results from EM methods are often part of multi-disciplinary studies integrating data from rock physics and other geophysical, geochemical, and geological methods to investigate complex subsurface structures and their temporal evolution. Neighbouring fields of research encompass the study of natural and controlled EM sources, geo-magnetically induced currents, space weather, or geomagnetic field studies based on observatory data.

Scientific drilling through the International Ocean Discovery Program (IODP) and the International Continental Scientific Drilling Program (ICDP) continues to provide unique opportunities to investigate the workings of the interior of our planet, Earth’s cycles, natural hazards and the distribution of subsurface microbial life. The past and current scientific drilling programs have brought major advances in many multidisciplinary fields of socio-economic relevance, such as climate and ecosystem evolution, palaeoceanography, the deep biosphere, deep crustal and tectonic processes, geodynamics and geohazards. This session invites contributions that present and/or review recent scientific results from deep Earth sampling and monitoring through ocean and continental drilling projects. Furthermore, we encourage contributions that outline perspectives and visions for future drilling projects, in particular projects using a multi-platform approach.

The recent methodological and instrumental advances in paleomagnetism and magnetic fabric research further increased their already high potential in solving geological, geophysical, and tectonic problems. Integrated paleomagnetic and magnetic fabric studies, together with structural geology and petrology, are very efficient tools in increasing our knowledge about sedimentological, tectonic or volcanic processes, both on regional and global scales. This session is intended to give an opportunity to present innovative theoretical or methodological works and their direct applications in various geological settings. Especially welcome are contributions combining paleomagnetic and magnetic fabric data, integrating various magnetic fabric techniques, combining magnetic fabric with other means of fabric analysis, or showing novel approaches in data evaluation and modelling. We also highly solicit contributions showing all aspects of paleomagnetic reconstructions, acquisition of characteristic remanence and remagnetisations applied to solving geotectonic problems.

Paleomagnetic and rock magnetic methods are important for assigning both absolute and relative time to geological sequences. Magnetostratigraphy and correlation to the Geological Polarity Time Scale (GPTS) constitute a standard dating and correlation tool in the Earth sciences, applicable to a wide variety of sedimentary rock types formed in different environments. Astronomically-forced climate cycles encoded by rock magnetics have enabled high-resolution time calibration of sedimentary sequences. These techniques allow improvement of the GPTS, better dating of the geological record, increased understanding of paleoclimatic and paleoenvironmental changes, and resolution of sedimentation dynamics in tectonically active basins. This session invites contributions that use magnetostratigraphy to date and correlate sedimentary sequences and rock magnetic measurements to assign high-resolution chronostratigraphy to sedimentary sequences.

The Earth's magnetic field varies on a wide range of spatial and temporal scales. During the last millennia, these variations have been characterized by some significant features, such as the Levantine Iron Age and South Atlantic anomalies. On longer timescales, variations are characterised by transitional events (i.e., geomagnetic excursions and reversals) associated with very low intensities and significant directional deviations. To decipher the past evolution of the geomagnetic field, paleomagnetic records from sediments, archaeological artifacts, and lava flows are needed. These records also allow the past reconstruction of the geomagnetic field at regional and global scales, and help to understand the geodynamo processes in the Earth’s core, providing constraints for geochronological applications and geodynamo simulations. In addition, records of cosmogenic isotope production rates can offer an independent proxy of the past geomagnetic field variations.
In this session, we invite contributions that present new knowledge of the past geomagnetic field. In that context, the session aims to bring new paleomagnetic records from globally distributed geographic areas and covering all timescales; and applications of new and novel techniques to develop regional and global models.

Greenhouse gas emissions, resource extraction, pollution and other environmental pressures are globally destabilising climates and ecosystems that provide the basis for human (and non-human) living. Humans take a dual role in this relationship as the main driver/cause of environmental change, but also as subjects of that change.
This interdisciplinary session aims to bring together three broad research questions that highlight different aspects of the human-environment system.
(a) To what extent can environmental impacts be avoided by tackling important drivers of energy and material use?
(b) What are the potentials and limitations for a demand-side transformation that reduces environmental pressures?
(c) How does environmental change affect the demand for energy and materials?
We welcome analyses across individual, societal and system level, and encourage an explicit consideration of how the assessed human-environment interaction is affected by the characteristics of the socio-technical and political-economic provisioning systems that link resource use to social outcomes in the study context.
We welcome presentations that spur discussion between different disciplines and address crucial questions that deal with consumption and possible limits to sustaining current levels or growing resource use. We encourage studies from a wide range of disciplines and methodological underpinnings, including but not limited to ecological economics, societal metabolism, social provisioning, human needs, and integrated assessment modelling and scenario building.
The session disentangles human-environment interactions especially in the context of the Paris Agreement climate targets. It hopes to provide multiple perspectives on the challenges and potential for living in a world where human well-being for all can be achieved with minimal environmental impact and within planetary boundaries. This could include studies on drivers of energy and resource use, potentials and limitations of decoupling, infrastructure needs and reform, improvements in service provisioning, as well as deeper changes in the mode of production and consumption and in socio-technical / political-economic systems or regimes (e.g., post-growth, efficiency, sufficiency, avoid-shift-improve, lifestyles, circular economy, alternative need satisfiers). This also calls for studies exploring alternative scenarios and modelling methods with different socioeconomic futures and distributional implications.

Climate change is debated most often for its environmental and socioeconomic repercussions; however, it also has a dramatic impact on tangible cultural heritage worldwide. The safeguard and fruition of cultural assets – outdoors or indoors, and either on land, underground, or underwater – are jeopardized by the current and expected environmental changes. The behavior of the component materials varies likewise, in response to global warming, sea level rise, ocean acidification, and the increase of extreme weather events.
This session addresses the climate change risk to cultural heritage from the interdisciplinary perspective of geosciences, which represent a valuable support for investigating the properties and durability of the materials (e.g., stones, ceramics, mortars, pigments, glasses, and metals); their vulnerability and the changes in weathering dynamics; the key environmental variables (pertaining to climate, microclimate, air pollution, water and soil composition) and the effects of extreme events; the techniques and products to improve conservation practices; and the adaptation measures for heritage protection. This session welcomes contributions based on approaches including but not limited to field and laboratory analysis and testing; damage assessments and simulations; modelling of risk scenarios and decay trends; strategies of monitoring and remote investigation; and processing of environmental databases.

The impact of human activity in the geosphere is becoming widespread and increasingly common. We are creating gigatons of solids each year which make their way into the environment, ranging from discarded municipal wastes such as plastics to industrial products such as iron- and steel-making slags. However, many of these materials, termed here anthropogenic geomaterials, can be utilised for sustainability purposes, for example reuse of fly ash or slag in concrete. This session invites contributions involving applications of anthropogenic geomaterials for a sustainable future. Examples might include valorisation of anthropogenic geomaterials for environmental benefits such as atmospheric CO2 mineralisation or biodiversity enhancement, or reuse/reprocessing of anthropogenic geomaterials in new products needed for a sustainable future such as low-carbon concrete or batteries.

Over the last decade, the transition towards low-carbon and renewable energy systems (RES) has accelerated significantly around the world. This has been in response to both national and international policies as well as incentives promoting the decarbonisation of energy systems to meet climate change targets. However, the low-carbon energy transition has precipitated expansive land use or ecosystem change, recognised by the IPBES as the greatest drivers of ecosystem degradation. Subsequent impacts on biodiversity and related ecosystem processes have major implications for natural capital (NC) and ecosystem service (ES) provision within and beyond the hosting ecosystem.
The objective of this session is to pool ecological, technological and societal research and gather new evidence and insights from around the world on the effects of the low-carbon energy transition on terrestrial and aquatic ecosystems relating to NC and ES. This session also aims to explore innovative methods to enhance the ecosystem sustainability of the low-carbon energy transition. Studies may (but are not limited to):
• Present the effects of different RES (e.g., solar energy, wind energy, biogas, smart and decentralised energy systems) on specific pools of NC (e.g., soil, water, atmosphere, habitat, biodiversity, biotic resources) and/or the provision of ES (e.g., nutrient cycling, local climate regulation, biomass production, pollination);
• Discuss the implications of the energy transition to the long-term sustainability of different hosting ecosystems (e.g., temperate grasslands, arid ecosystems, aquatic or marine systems) or human-made systems (e.g., arable land);
• Discuss the societal implications of increased RES (e.g., community acceptance of changing natural/semi-natural landscapes);
• Discuss the policy implications (at national or international level) and potential economic consequences of incorporating NC and ES in the land use decision-making process when planning for RES;

This combined session aims to provide extensive overview of different methodologies applied to pursue the achievement of one or more Sustainable Development Goals as well as to address issues related to national GHG reporting.
In one part session includes submissions related to global or regional applications of geospatial data analysis techniques to address sustainability challenges (land, energy, water, climate, infrastructure, vegetation, health etc.) and their interactions. Contributions aiming at improving the understanding, planning, and evaluation of technological, environmental and policy solutions pursuing the achievement of one or more Sustainable Development Goals (SDGs) will be considered. The main methodological requirement is the use of GIS data (from earth observation, in-situ collection, or statistical offices) and manipulation tools to develop and apply innovative methodologies leveraging bottom-up, spatially-explicit information and highlighting their benefits vis-à-vis aggregated, top-down analysis. Preference will be given to studies which are broader in geographical scope, and which can be scaled to other contexts.
Also, session will emphasize the importance of LULUCF sector in reaching the long-term climate mitigation objective. Contributions related to national and subnational carbon budget estimates (past, present and future) in different land uses (forests, crops, grasslands, urban areas), using multiple data sources and different calculation methods, will be considered. NFI-based, remote sensing and modelling studies on C stocks and/or fluxes in different ecosystem pools (live biomass, dead wood, litter or soil) are encouraged. Aim is to highlight main issues regarding data integration and model calibration and validation process.
Nature-Based Solutions and Climate Engineering in Climate Governance
As reaching the Paris agreement goal of limiting the global mean surface warming even below 2ºC becomes increasingly difficult with only emission reduction, additional measures complementing greenhouse gas (GHG) emission reductions to limit global warming gain more attention: Nature-based Solutions and Climate Engineering.
Nature-based solutions (NbS) have gained popularity as a set of integrated approaches that contribute to climate change adaptation, slowing further global warming, supporting ecosystem services and biodiversity, while promoting sustainable development. To achieve the full potential of NbS to address climate change, there is an urgent need for multidisciplinary teams of scientists to articulate solutions that engage policy makers and enable NbS interventions to reduce carbon emissions while benefiting human well-being. This will require systemic change in the way we conduct research, promote collaboration between institutions and with policy makers.
Climate Engineering (CE) is much more controversial. Carbon Dioxide Removal (CDR) aims at removing CO2 from the atmosphere through techniques such as ocean fertilization, artificial upwelling or enhanced weathering. CE has been criticized for creating potentially dangerous side effects, distracting from the root cause of climate change (GHG emissions), and being difficult to govern. So what, if any, should be the future role of CDR and SRM in the climate governance toolbox and to what extent should CE research have high priority? which knowledge gaps must be addressed before a decision for or against these techniques can be taken?
This session aims to advance knowledge of innovative NbS approaches for more inclusive and resilient communities from inter-disciplinary perspectives.
Specific topics include, but are not limited to:
— Benefits: The potential of NbS and CE to help achieving climate goals
— Feasibility: Tools and best practices enabling successful implementation and upscaling of NbS; impact assessment of real-life NbS projects, especially for the Global South and developing countries; and technical feasibility and risks in implementing CE
— Viability: Cost-benefit analysis of NbS and CE to multiple Sustainable Development Goals
— Governance: New NBS governance models and co-creation approaches and tools; and regional and global challenges and solutions for fair and inclusive governance of CE.

In a fast-changing environment, earth’s ecosystems are facing multiple stressors compromising the provision of essential services for mankind, and the resiliency of the natural environment itself.
Climate change, water pollution and scarcity affect biodiversity, socio-economic and climate related vulnerabilities and as a consequence, water and food security and human health.
The recent European Green Deal aims at Europe becoming the world’s first climate-neutral continent by 2050 and it does so by setting climate, energy, transport and taxation policies fit for reducing net greenhouse gas emissions by at least 55% by 2030. This program sets ambitious yet realistic targets for the next decades, auspicating the transformation of European Countries into a modern resource-efficient economy and society in line with the Sustainable Development Goals.
However, to address both the impacts as well as the causes of climate change, it is fundamental to create conditions where ecosystem services are optimized for both the local population and global objectives. Yet, the use of ecosystem services assessment in decision making might prove challenging when it comes to economic and social domains, as well as the perception and concept of natural environment may differ across disciplines. Such transdisciplinary approach plays a key role in Nature Based Solutions and opens up to the participation of multiple stakeholders in local governance, thus offering a multitude of co-benefits for the environment and for communities.
This session aims at opening a common ground between the natural, physical, social and economic sciences towards a resilient planet, by providing examples of challenges and opportunities and harmonizing best practices in this field.
We welcome transdisciplinary contributions on terrestrial, marine, and urban ecosystem services assessment that take into account the natural and the human dimension, advance in modelling complex spatio-temporal and social dynamics and transdisciplinary approaches towards nature inspired and supported solutions for social benefits and ecosystems’ resilience.

Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

Groundwater, the hidden component of the water cycle, traditionally receives less attention than surface water from both the scientific community and policy makers, due to it being "out of sight, out of mind". However, this precious resource is inextricably linked to the maintenance of natural ecosystems and human well-being. Groundwater has always been part of the lives of worldwide communities: irrigated agriculture is primarily sustained by groundwater resources, particularly in arid and semi-arid regions; holy wells and sacred springs are part of our global cultural heritage, while disagreement over groundwater resources have previously resulted in turmoil and national/transboundary conflicts. These obvious interconnections, however, are neglected in favour of the development of sectorial approaches to groundwater resource assessment.
Socio-hydrogeology has recently been proposed as an effective approach to addressing complex groundwater-related issues in an increasingly holistic and integrated manner. By focusing on the reciprocity between humans and groundwater, it aims to explore and understand their dynamic interactions and feedbacks with a final goal of developing transdisciplinary solutions for transdisciplinary problems. Due to the more "personal" (i.e., individual household/community supplies) and local nature of groundwater in many instances, socio-hydrogeology seeks to understand individuals and communities as a primary source, pathway and receptor for potable groundwater supplies, including the role of local knowledge, beliefs, risk perception, tradition/history, and consumption. In essence, the “socio” in socio-hydrogeology embodies sociology, including social, cognitive, behavioural and socio-epidemiological science.
For this session we encourage contributions from diverse fields, including:
• Examples of socio-hydrogeological assessments (e.g., participatory monitoring, stakeholder engagement, public participation, citizen science)
• Integration of “non-expert” knowledge and experience within quantitative and qualitative hydrogeological studies
• Challenges and opportunities arising from the integration of hydrogeology and social sciences
• Social and political approaches to water resources research
• Groundwater geoethics and national/transboundary conflicts
• Attempts to integrate behavioural, experiential or knowledge-based data with hydrogeological/health risk assessment models
• Educational goals for future socio-hydrogeologists

Environmental systems often span spatial and temporal scales covering different orders of magnitude. The session is oriented toward collecting studies relevant to understand multiscale aspects of these systems and in proposing adequate multi-platform and inter-disciplinary surveillance networks monitoring tools systems. It is especially aimed to emphasize the interaction between environmental processes occurring at different scales. In particular, special attention is devoted to the studies focused on the development of new techniques and integrated instrumentation for multiscale monitoring of high natural risk areas, such as volcanic, seismic, energy exploitation, slope instability, floods, coastal instability, climate changes, and another environmental context.
We expect contributions derived from several disciplines, such as applied geophysics, geology, seismology, geodesy, geochemistry, remote and proximal sensing, volcanology, geotechnical, soil science, marine geology, oceanography, climatology, and meteorology. In this context, the contributions in analytical and numerical modeling of geological and environmental processes are also expected.
Finally, we stress that the inter-disciplinary studies that highlight the multiscale properties of natural processes analyzed and monitored by using several methodologies are welcome.

The session gathers geoscientific aspects such as dynamics, reactions, and environmental/health consequences of radioactive materials that are massively released accidentally (e.g., Chernobyl and Fukushima nuclear power plant accidents, wide fires, etc.) and by other human activities (e.g., nuclear tests).
The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Thus, the radioactive contamination problem is multi-disciplinary. In fact, this topic involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic and ecosystem, and its relations with human and non-human biota. The topic also involves hazard prediction and nowcast technology.
By combining 35 years (> halftime of Cesium 137) monitoring data after the Chernobyl Accident in 1986, 10 years dense measurement data by the most advanced instrumentation after the Fukushima Accident in 2011, and other events, we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents.
The following specific topics have traditionally been discussed:
(a) Atmospheric Science (emissions, transport, deposition, pollution);
(b) Hydrology (transport in surface and ground water system, soil-water interactions);
(c) Oceanology (transport, bio-system interaction);
(d) Soil System (transport, chemical interaction, transfer to organic system);
(e) Forestry;
(f) Natural Hazards (warning systems, health risk assessments, geophysical variability);
(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).
The session consists of updated observations, new theoretical developments including simulations, and improved methods or tools which could improve observation and prediction capabilities during eventual future nuclear emergencies. New evaluations of existing tools, past nuclear contamination events and other data sets also welcome.

Hydroclimatic conditions and availability of water resources in space and time constitute important factors for maintaining adequate food supply, the quality of the environment, and the welfare of citizens and inhabitants, in the context of a post-pandemic sustainable growth and economic development. This session is designed to explore the impacts of hydroclimatic variability, climate change, and temporal and spatial availability of water resources on different factors, such as food production, population health, environment quality, and local ecosystem welfare.
We particularly welcome submissions on the following topics:
• Complex inter-linkages between hydroclimatic conditions, food production, and population health, including: extreme weather events, surface and subsurface water resources, surface temperatures, and their impacts on food security, livelihoods, and water- and food-borne illnesses in urban and rural environments.
• Quantitative assessment of surface-water and groundwater resources, and their contribution to agricultural system and ecosystem statuses.
• Spatiotemporal modeling of the availability of water resources, flooding, droughts, and climate change, in the context of water quality and usage for food production, agricultural irrigation, and health impacts over a wide range of spatiotemporal scales.
• Smart infrastructure for water usage, reduction of water losses, irrigation, environmental and ecological health monitoring, such as development of advanced sensors, remote sensing, data collection, and associated modeling approaches.
• Modelling tools for organizing integrated solutions for water supply, precision agriculture, ecosystem health monitoring, and characterization of environmental conditions.
• Water re-allocation and treatment for agricultural, environmental, and health related purposes.
• Impact assessment of water-related natural disasters, and anthropogenic forcing (e.g. inappropriate agricultural practices, and land usage) on the natural environment (e.g. health impacts from water and air, fragmentation of habitats, etc.)

The world's energy, water, and land systems are in transition and rapidly integrating, driven by forces such as socioeconomic, demographic, climatic, and technological changes as well as policies intended to meet Sustainable Development Goals (SDGs) and other societal priorities. These dynamics weave across spatial scales, connecting global markets and trends to regional and sub-regional economies. At the same time, resources are often locally managed under varying administrative jurisdictions closely tied to inherent characteristics of each commodity such as river basins for water, grid regions for electricity and land-use boundaries for agriculture. Local decisions, in turn, are critical in deciding the aggregate success and consequences of national and global policies. Thus, there is a growing need to better characterise the energy-water-land nexus to guide robust and consistent decision making across these scales under changing climate.
This session aims to address this challenge for the energy-water-land nexus in nascent infrastructure planning and sectoral transitions. Contributions can include work dealing with applications of existing nexus approaches in sustainability assessment and design of future developments at different scales (i.e. urban to regional planning), as well as new methods that address existing gaps related to incorporating processes at different scales, bridging data gaps, improving optimisation approaches, or dealing with transboundary issues.

Wind and solar power are the predominant new sources of electrical power in recent years. Several countries or regions regularly exceed 100% of variable renewable energy in their grids. By their very nature, wind and solar power, as well as hydro, tidal, wave and other renewable forms of generation are dependent on weather and climate. Modelling and measurement for resource assessment, site selection, long-term and short term variability analysis and operational forecasting for horizons ranging from minutes to decades are of paramount importance.
The success of wind power means that wind turbines are increasingly put in sites with complex terrain or forests, with towers extending beyond the strict logarithmic profile, and in offshore regions that are difficult to model and measure. Major challenges for solar power are notably accurate measurements and the short-term prediction of the spatiotemporal evolution of the effects of cloud field and aerosols. Planning and meteorology challenges in Smart Cities are common for both.
For both solar and wind power, the integration of large amounts of renewable energy into the grid is another critical research problem due to the uncertainties linked to their forecast and to patterns of their spatio-temporal variabilities.
We invite contributions on all aspects of weather dependent renewable power generation, e.g.:
• Wind conditions (both resources and loads) on short and long time scales for wind power development, especially in complex environments (e.g. mountains, forests, coastal or urban).
• Inter-annual variability of solar and wind resource.
• Typical Meteorological Year and probability of exceedance for wind and solar power development.
• Wind and solar resource and atlases.
• Wake effect models and measurements, especially for large wind farms and offshore.
• Performance and uncertainties of forecasts of renewable power at different time horizons and in different external conditions.
• Forecast of extreme wind events and wind ramps.
• Local to global impacts of renewable energy power plants or of large-scale integration.
• Dedicated wind measurement techniques (SODARS, LIDARS, UAVs etc.).
• Dedicated solar measurement techniques (pyranometric sensors, sun-photometer, ceilometer, fish-eye cameras, etc.) from ground-based and space-borne remote sensing.
• Tools for urban area renewable energy supply strategic planning and control.
Other related topics will be considered by the conveners.

This session addresses spatial and temporal modelling of renewable energy systems, both in a prospective as well as in a retrospective manner. Therefore, contributions which model the characteristics of future renewable energy systems are equally welcome as contributions which assess the characteristics of the past performance of renewable energies. Session contributions may reach from purely climate based assessments of simulated renewable generation time series, over assessments of land use to full energy system models used to better understand energy systems with high shares of renewables.
Studies may for instance
Improve our understanding of how climate data can be used to model renewables
Show the spatial and temporal variability of renewable energy sources
Assess the complementarity of different renewable energy sources or locations
Derive land availability scenarios for renewable energies based on climatic, technical, economic, or social criteria
Assess past spatial deployment patterns of renewables
Assess past impacts on land cover and land-use change, including impacts on biodiversity and other environmental indicators
Derive integrated scenarios of energy systems with high shares of renewables (Including systems from the local scale e.g. in form of local Energy Communities to the national or continental scale).
The objective of the session is to provide an insight into recent advances in the field of renewable energy system modeling. The session welcomes papers dedicated to climatic and technical issues, environmental impact assessments, and policy-making, forecasting and real time applications concerning renewable energy systems.

Geothermal energy is often viewed as a source of green, ideally renewable, energy. The sustainability of geothermal exploitation, however, has many aspects and needs to be looked at in more detail. Geothermal’s sustainability applies to three distinct topics.
On the one hand, the sustainability of reservoir exploitation plays an important role if operators plan on using geothermal waters of a specific aquifer over a long period without short-circuiting and without changing the hydraulic, hydrogeochemical and mechanical properties of the reservoir. On the other hand, operation strategies, quality of equipment, and hydrochemical signatures of the exploited reservoir waters impact and limit the sustainability of geothermal equipment such as pipes and pumps.
Lastly, the contribution hydrothermal energy is able to make towards an efficient energy transition in the name of climate change mitigation needs to be investigated further, especially considering its inherent low degree of efficiency, its environmental impacts at the well site and overall social acceptance.
This session aims at an interdisciplinary platform addressing the overarching aspects of geothermal exploitation and its role in environment protection. While still technical, we also invite stakeholders and policy makers to discuss whether the socio-economic and legal frameworks require adjustments to promote geothermal energy.
This session will focus on, but is not limited to:
- Impacts of stimulation, exploitation, and any water treatment on the reservoir
- Strategies for assessment and monitoring of the sustainability of geothermal reservoir exploitation (case studies and success stories)
- Impacts of chemical properties of the water on geothermal equipment (corrosion, scaling…)
- Life cycle assessments of geothermal systems
- Geothermal emissions of equipment manufacturing and operation of geothermal power plants
- Impacts on biodiversity/integrity of ecosystems in the geothermal reservoirs
- Social acceptance, community engagement, position in the current legal framework

With an increasing demand for low-carbon energy solutions, the need of geothermal resources utilization is accelerating. Geothermal energy can be extracted from various, often complex geological settings, e.g. fractured crystalline rock, magmatic systems or sedimentary basins. Current advancements also target unconventional systems (e.g., Enhanced Geothermal Systems, super-hot, pressurized and co-produced, super-critical systems) besides conventional hydrothermal systems. Optimizing investments leads to the development of associated resources such as lithium, rare earths and hydrogen. This requires a joint effort for monitoring, understanding and modelling geological systems that are specific to each resource.
A sustainable use of geothermal resources requires advanced understanding of the properties of the entire system during exploration as well as monitoring, including geophysical properties, thermo-/petro-physical conditions, fluid composition; structural and hydrological features; and engineering challenges. Challenges faced are, among others, exploration of blind systems, reservoir stimulation, induced seismicity or related to multiphase fluid and scaling processes.
The integration of analogue field studies with real-life production data, from industrial as well as research sites, and their organization and the combination with numerical models, are a hot topic worldwide. With this session we aim to gather field, laboratory and numerical experts who focus their research on geothermal sites, to stimulate discussion in this multi-disciplinary applied research field. We seek for contributions from all disciplines, ranging from field data acquirements and analysis to laboratory experiments, e.g. geophysical surveys or geochemical experiments, and from the management and organization of information to numerical models as well as from (hydro)geologists, geochemists, (geo)physicists, surface and subsurface engineers.
The session welcomes contributions about shallow geothermal energy applications, including traditional closed- and open-loop borehole heat exchangers as well as so-called energy geostructures (e.g. thermo-active foundations, walls, tunnels).
Different types of analysis and approaches are relevant to this session, spanning from the evaluation of ground thermal properties to the mapping of shallow geothermal potential, from energy storage and district heating to sustainability issues and consequences of the geothermal energy use, from the design of new heat exchangers and installation techniques to the energy and thermo-(hydro-) mechanical performance of energy geostructures, from the local behaviour of a heat exchanger to the city scale implementation of energy geostructures. Contributions based on experimental, analytical and numerical modelling are welcome as well as interventions about legislative aspect.

Hydropower is a mature and cost-competitive renewable energy source, which helps stabilize fluctuations between energy demand and supply. The structural and operational differences between hydropower systems and renewable energy farms may require changes in the way hydropower facilities operate to provide balancing, reserves or energy storage. Yet, non-power constraints on hydropower systems, such as water supply, flood control, conservation, recreation, navigation may affect the ability of hydropower to adjust and support the integration of renewables. Holistic approaches that may span a range of spatial and temporal scales are needed to evaluate hydropower opportunities and support a successful integration maintaining a resilient and reliable power grid. In particular, there is a need to better understand and predict spatio-temporal dynamics between climate, hydrology, and power systems.
This session solicits academics and practitioners contributions that explore the use of hydropower and storage technologies to support the transition to low-carbon electricity systems. We specifically encourage interdisciplinary teams of hydrologists, meteorologists, power system engineers, and economists to present on case studies and discuss collaboration with environmental and energy policymakers.
Questions of interest include:
- Prediction of water availability and storage capabilities for hydropower production
- Prediction and quantification of the space-time dependences and the positive/negative feedbacks between wind/solar energies, water cycle and hydropower
- Energy, land use and water supply interactions during transitions
- Policy requirements or climate strategies needed to manage and mitigate risks in the transition
- Energy production impacts on ecosystems such as hydropeaking effects on natural flow regimes.

Storage of energy and carbon dioxide in subsurface geological formations is of key importance in the green shift: relying on renewables, zero carbon power and heat generation. The suitability of subsurface storage sites depends on the properties and integrity of the reservoir and its confining units under thermal, mechanical, hydraulic and chemical stress. Secure subsurface storage requires geological knowledge and sound risk evaluations, which in turn is essential for obtaining public acceptance of these technologies. This session offers a platform for inter-disciplinary scientific exchange between different branches of storage expertise. It addresses storage of fluids in geological reservoirs at all scales, from laboratory experiments to full-scale storage projects. Individual studies and active projects integrating elements of the storage chain as well as field projects focused on geological storage as pathways for a low carbon future are invited.
Relevant topics include but are not limited to:
• Regional and local characterization of storage formations, caprocks, and faults as well as their behaviour during injection and storage, including long-term response
• Evaluation of available infrastructure and injection strategies, physical and chemical reservoir response
• Geophysical and geochemical monitoring for safe and cost-efficient storage
• Coupling of different energy storage types in a carbon neutral power system
• Heat exchange systems, including geothermal energy utilization
• Public perception of subsurface storage in energy systems
Suitable contributions can address, but are not limited to:
• Field testing and experimental approaches aimed at characterizing the site, its key characteristics and the behaviour of the injected fluid
• Studies of natural analogue sites and lessons learnt for site characterisation and monitoring techniques
• Laboratory experiments investigating fluid-rock-interactions
• Risk evaluations and storage capacity estimates
• Numerical modelling of injectivity, fluid migration, trapping efficiency and pressure response as well as simulations of geochemical reactions

The successful implementation of safe deep geological disposal of spent fuel, high-level waste and other long-lived radioactive waste is one of the currently most pressing environmental challenges in several countries worldwide. Site investigation and selection are primarily geoscientific tasks that require interdisciplinary collaboration of different disciplines, like geophysics, hydrogeology, (hydro-)geochemistry, mineralogy, geomechanics, material science, and geological as well as THMC modelling. Moreover, successful and socially accepted site selection and disposal implementation depend not only on geoscientific state-of-the-art results, sound engineering and R&D programs but to a large extent on well-designed public outreach and public involvement/participation activities as well as on suitable regulatory frameworks.
As for other subsurface technologies such as the storage of thermal energy and other energy carriers, or the deposition of chemotoxic waste or carbon dioxide, barrier integrity is a crucial aspect for the assessment of nuclear waste disposal. Numerical simulations, in conjunction with experimental studies are an integral part of safety and environmental-impact assessment concepts involving barrier integrity as a key component. Reliable comparative analyses of potential technological options require coupled THMC models capturing the particularities of each rock type and associated repository concept to a comparable level of sophistication. Structural as well as process complexity are often met by data scarcity and variability, necessitating the treatment of uncertainties and variability.
Aside from geoscientific and technological aspects this interdisciplinary session also addresses social and regulatory challenges by welcoming contributions from research and technical support organizations, waste management organizations, regulatory bodies, and NGOs. The session provides a platform for the exchange of i) geoscientific, geochemical, geotechnical and material science knowledge for assessing the integrity of multi-barrier systems considering equally conceptual, theoretical, computational and experimental aspects as well as ii) safety assessment strategies and tools, disposal concepts, national and transnational public outreach and involvement programs, siting approaches and relevant regulatory frameworks. Presentations related to other subsurface technologies that face comparable challenges are also welcome.

Geoscience knowledge is essential to investigate safety requirements that are established by national agencies to construct a geological disposal for high-level and/or long-lived radioactive waste in a specific selected site. Safety requirements include isolation of the nuclear waste from humans and the accessible biosphere, containment by retention and retardation of contaminants, limited water flow to the geo-engineered facility and long-term geological stability of the site. Experiences in many countries have shown that acceptable conditions for selecting a construction site can be found in diverse rock types as granites, metamorphic basement rocks, plastic clays, indurated claystones, evaporites, porous volcanic tuffs and highly compacted volcanic tuffs.
Geoscientist are tackling challenging issues to support the site selection process. These include hydraulic testing in low permeability formations, appropriate selection of borehole testing fluids, porewater characterization, radionuclide-rock and rock-water interactions, geo-mechanical testing of clay rocks, characterization and classification of fractures in crystalline rock, fracture network modelling, development of long-term site evolution models, management of large amount of data obtained during the site characterization phase, integration of diverse geoscientific data and the development of plausible future evolution scenarios. For this reason, in this session, relevant topics included, but not limited are:
• Data digitalization/management and parameter collection
• Development of new methodologies for site characterization (i.e., rock characterization)
• Laboratory-scale, underground research laboratories and large-scale mock-up experiments
• Radionuclide migration in rocks
• Natural analogues and/or full scale in situ testing

The rejuvenated International Commission on Geoheritage is all set to unveil statues for designation of ‘Global Heritage Stone Resource’. The idea is to promote the heritage /natural stones with Outstanding Universal Value vis-à-vis their cultural, architectural, and Utilitarian parameters.
Our session deals with promoting heritage/natural stones of Outstanding Universal Value which contributed to the evolution of human culture and architecture from the entire world in agreement with the goals of the IUGS-ICG-HSS and IGCP HerSTONES project (2020-2024). The session invites papers on diverse themes such as the impact of heritage stones in the evolution of human cultures, architectural legacy, sustainability of historical quarries, preservation, and sustainable restoration of the urban and rural stone-built heritage.
Selected contributions from our previous EGU sessions were published in high impact factor journals, such as Geological Society of London Special Publications (SP407: Global Heritage Stone: Towards International Recognition of Building and Ornamental Stones), Episodes Special Issue on Heritage Stones (volume 38-2, June 2015), Geoscience Canada (volume 43(1), March 2016), Geoheritage (2018), Episodes (volume 44 (1) March 2021). Currently, the contributions from our session at EGU 2021 are in preparation for publication in the journal Geoheritage. Selected contributions of EGU 2022 will be considered for publication in a special issue of a well-rated journal.

Material recovery is critical to recoup as much as of the waste economic and ecological value (Thierry et al., 1995). In the Circular Economy, this is of the utmost importance to close material loops and re-design production and consumption patterns in a more restorative and regenerative fashion (Morseletto, 2020). Indeed, different types and levels of material recovery can soothe the pressure on raw material extraction and hopefully reduce the ultimate quantities of waste.
Material recovery plays a leading role in the current quest for circularity. Therefore, we are interested in hosting studies looking at the circular use of wastes for material recovery. We welcome and encourage interdisciplinary approaches to the topic. Potential research issues include but are not limited to the following:
1. Resource extraction/recovery from wastes;
2. Metals and Rare Earth Elements (REE) extraction and recovery techniques;
3. Reuse of waste materials in construction;
4. Techniques that perform resource recovery;
5. Drawbacks of and barriers to material recovery;
6. Digital technologies for material recovery;
7. Material recovery for Industrial Symbiosis;
8. Business models and practices for Material Recovery.

The demand for raw materials and critical raw materials, to supply the needs of both society and industry, is continuously growing, imposing environmental, societal, and technological challenges.
These activities are inevitably accompanied by the production of large volumes of residues, through both exploitation and processing.
In the past, mining activity and extractive waste management were approached, mainly considering the environmental hazards and landscape degradation, but, nowadays, the development of innovative and technological processes, that allow us to reduce, reuse and recycle such industrial residues, as well as more sustainable exploitation practices, give us the opportunities to exploit the huge volumes of past mineral waste as an important source of raw materials.
Residues, such as waste rock, tailings, slags and fly ashes, often hold impressive residual mineral values, and have the potential to be converted to secondary raw materials and mineral resources, for these reasons further challenges are the geochemical, petrographic and mineralogical characterization and the modelization of waste deposits to realistically assess the prospects for sustainable exploitation. It must become the norm to maximize resource use, reduce the volume for final disposal, and also mitigate the risk of environmental damage, associated with the increasing global demand for raw materials and minerals resources.
The main topics to be discussed in this session address, but are not limited to:
- Characterization of geomaterials, their environmental interactions, and decay
- Characterization of industrial residue resources and their environmental assessment
- Secondary raw materials exploitation and valorisation

Research and innovation in exploration and mining of raw materials is increasingly focused on the prospect of developing completely new methods and technologies to find and exploit new mineral deposits within Europe. Amongst these technologies, robotisation and miniaturisation of exploration/production platforms (robotic autonomous explorers & miners) allow to reconsider “non-economical” deposits (abandoned, small, ultra-depth), extract them in a socially and environmentally responsible way, and produce useful metallurgical products which can be used further-on for manufacturing.
Underground operation of an autonomous or semi-autonomous underground platform is an extremely challenging problem where solution have to come from the close collaboration of robotic engineers, mining engineers, mineralogists, geochemists, geophysicians and structuralists to solve challenges as diverse as locomotion in water or slurries, localization and mapping in relationship with an orebody, automated extraction planning, optimization of extraction tools, and real-time selective mineralogy.
Contributions from geologists, geophysicists, mining engineers, robotic engineers, software developers are welcome.
Mineral deposits represent principal sources of metallic and non-metallic raw materials for our society. The implementation of new climate policies and the rise of green energy production and use will trigger an unprecedented demand increase for such resources. Formation of economic commodities requires component sequestration from source region, transport and focusing to structural or chemical barriers. These enrichment processes typically involve magmatic, hydrothermal, weathering or metamorphic events, which operate in diverse geodynamic settings and over various time scales. The scope of this session is to collect insights from diverse areas of mineral exploration, field, analytical or experimental studies of mineral deposits as well as resource characterization and extraction. We invite contributions from fields of economic geology, mineralogy and geochemistry in order to advance our understanding of ore-forming systems.

Dissolution, precipitation, and chemical reactions between infiltrating fluid and rock matrix alter the composition and structure of the rock, either creating or destroying flow paths. Strong, nonlinear couplings between the chemical reactions at mineral surfaces and fluid motion in the pores often leads to the formation of intricate patterns: networks of caves and sinkholes in karst area, wormholes induced by the acidization of petroleum wells, porous channels created during the ascent of magma through peridotite rocks. Dissolution and precipitation processes are also relevant in many industrial applications: dissolution of carbonate rocks by CO2-saturated water can reduce the efficiency of CO2 sequestration, mineral scaling reduces the effectiveness of heat extraction from thermal reservoirs, acid rain degrades carbonate-stone monuments and building materials.
With the advent of modern experimental techniques, these processes can now be studied at the microscale, with direct visualization of the evolving pore geometry. On the other hand, the increase of computational power and algorithmic improvements now make it possible to simulate laboratory-scale flows while still resolving the flow and transport processes at the pore-scale.
We invite contributions that seek a deeper understanding of reactive flow processes through interdisciplinary work combining experiments or field observations with theoretical or computational modeling. We seek submissions covering a wide range of spatial and temporal scales: from table-top experiments and pore-scale numerical models to the hydrological and geomorphological modelling at the field scale. We also invite contributions from related fields, including the processes involving coupling of the flow with phase transitions (evaporation, sublimation, melting and solidification).

Metallurgical slags are generated as a by-product of smelting during ironmaking, steelmaking, and the production of ferroalloys and non-ferrous metals. The formation conditions result in complex (geo)chemical and mineralogical characteristics unique to slags alone. Historically slags have been discarded as a waste product and, through release of potentially toxic trace elements, represent a hazard to the environment and human health. However, increasingly we are realizing the resource potential of what was previously thought of as waste, thus reducing the environmental impact and taking a step closer to a circular economy.
The aim of this short course is to is to give an overview on the environmental geochemistry and resource potential of metallurgical slags by summarizing processes for the generation of slags, describing their chemical and mineralogical characteristics, outlining the fundamental geochemistry that propels slag weathering, and illustrating the utilization of slags and resource recovery of valuable metals from slags. This short course is a follow up of a book entitled “Metallurgical Slags: Environmental geochemistry and Resource Potential” published in 2021 by the Royal Society of Chemistry and gives an overview useful for the environmental geochemists, geologists, mining and civil engineers, waste and resource managers, and all those interested and inspired by a circular economy and minimizing our environmental footprint on planet Earth.

Numerous cases of induced/triggered seismicity associated with anthropogenic activity resulting either directly or indirectly from injection/extraction related to geo-resources exploration have been reported in the last decades. Induced earthquakes felt by the general public can often negatively affect public perception of geo-energies and may hinder future geo-energy development. Furthermore, large earthquakes may jeopardize wellbore stability and damage surface infrastructure. Thus, monitoring and modeling processes leading to fault slip, either seismic or aseismic, are critical to developing effective and reliable forecasting methodologies during deep underground exploitation. The complex interaction between injected fluids, subsurface geology, stress interactions, and resulting fault slip requires an interdisciplinary approach to understand the triggering mechanisms and may require taking coupled thermo-hydro-mechanical-chemical processes into account.
In this session, we invite contributions from research aimed at investigating the interaction of the above processes during exploitation of underground resources, including hydrocarbon extraction, wastewater disposal, geothermal energy exploitation, hydraulic fracturing, gas storage and production, mining, and reservoir impoundment for hydro-energy. We particularly encourage novel contributions based on laboratory and underground near-fault experiments, numerical modeling, the spatio-temporal relationship between seismic properties, injection/extraction parameters, and/or geology, and fieldwork. Contributions covering both theoretical and experimental aspects of induced and triggered seismicity at multiple spatial and temporal scales are welcome.

Faults and fracture zones are fundamental features of geological reservoirs that control the physical properties of the rock. As such, understanding their role in in-situ fluid behaviour and fluid-rock interactions can generate considerable advantages during exploration and management of reservoirs and repositories.
Physical properties such as frictional strength, cohesion and permeability of the rock impact deformation processes, rock failure and fault/fracture (re-)activation. Faults and fractures create fluid pathways for fluid flow and allow for increased fluid-rock interaction.
The presence of fluids circulating within a fault or fracture network can expose the host rocks to significant alterations of the mechanical and transport properties. This in turn can either increase or decrease the transmissibility of a fracture network, which has implications on the viability and suitability of subsurface energy and storage projects. Thus, it is important to understand how fluid-rock interactions within faults and fractures may alter the physical properties of the system during the operation of such projects. This is of particular interest in the case of faults as the injection/ remobilisation of fluids may affect fault/fracture stability, and therefore increase the risk of induced seismicity and leakage.
Fieldwork observations, monitoring and laboratory measurements foster fundamental understanding of relevant properties, parameters and processes, which provide important inputs to numerical models (see session “Faults and fractures in geoenergy applications 1: Numerical modelling and simulation”) in order to simulate processes or upscale to the reservoir scale. A predictive knowledge of fault zone structures and transmissibility can have an enormous impact on the viability of geothermal, carbon capture, energy and waste storage projects.
We encourage researchers on applied or interdisciplinary energy studies associated with low carbon technologies to come forward for this session. We look forward to interdisciplinary studies which use a combination of methods to analyse rock deformation processes and the role of faults and fractures in subsurface energy systems, including but not restricted to outcrop studies, monitoring studies, subsurface data analysis and laboratory measurements. We are also interested in research across several different scales and addressing the knowledge gap between laboratory scale measurements and reservoir scale processes.
Naturally fractured reservoirs are of great importance in various disciplines such as hydrogeology, hydrocarbon reservoir management, nuclear waste repositories, CO2 storage and geothermal reservoir engineering. This session addresses novel ideas as well as established concepts for the representation and numerical simulation of discontinuities and processes in fractured media.
The presence of fractures modifies the bulk physical properties of the original media by many orders of magnitudes and often introduces strongly nonlinear behaviour. Fractures also provide the main flow and transport pathways in the rock mass, dominating over the permeability of the rock matrix and creating anisotropic flow fields and transport.
Numerical modelling of such systems is especially challenging and often requires creative new ideas and solutions, for example the use of stochastic models. Understanding the hydraulic and mechanical properties of fractures and fracture networks thus is crucial for predicting the movement of any fluid such as water, air, hydrocarbons, or CO2.
The geologist toolboxes for modelling fractured rocks and simulating processes in fractured media experiences constant extension and improvement. Contributions are especially welcome from the following topics:
• Deterministic or stochastic approaches for structural construction of fractured media
• Continuous or discontinuous (DFN) modelling methods representing static hydraulic and/or mechanical characteristics of fractured media
• Simulation of dynamic processes, hydraulic and/or mechanical behaviour and THMC coupling in fractured media
• Deterministic and stochastic inversion methods for calibrating numerical models of fractured media
• Numerical modelling concepts of accounting for fractured properties specifically in groundwater, petroleum or geothermal management applications
We encourage researchers to elaborate on applied projects on the role of faults and fractures in subsurface energy systems in our session. We are interested in research across different scales and disciplines and welcome warmly ECS.

Thermal, hydraulic and mechanical processes in aquifers are of increasing interest for hydrogeological analysis for development of innovative field and laboratory experiments. Both in research and in practice, accurate characterization of subsurface flow and heat transport, observations of induced or natural variations of the thermal regime. The seasonal and long-term development of thermal and mechanical conditions in aquifers, and heat transfer across aquifer boundaries are focus points. This also includes the role of groundwater in the context of geothermal energy use for predicting the long-term performance of geothermal systems (storage and production of heat), and integration in urban planning. There are many ongoing research projects studying heat as a natural or anthropogenic tracer, and which try to improve thermal response testing in aquifers. Such techniques are of great potential for characterizing aquifers, flow conditions, and crucial transport processes, such as mechanical dispersion. Understanding the interaction of hydraulic, thermal and mechanical processes is a major challenge in modern hydrogeology. Deep underground constructions, tunnels, CO2 storage, hydro- and enhanced geothermal applications are prominent subjects. We invite contributions that deliver new insight into advances in experimental design, reports from new field observations, as well as demonstration of sequential or coupled modeling concepts. The session aims to provide an overview of the current and future research in the field, covering any temporal or spatial scale, and seeks to address both separate and coupled processes.
Thermal Energy Storage is a key component for an efficient and low-carbon energy balance. TES allows a flexibility of storage volume and storage time, and represents a cross-sector technology. As it is coupling heat, cooling energy, and electricity, which still belong in most cases to completely different market sectors, there is currently a marginal integration among the operators.
The aim of this session is to increase the understanding on how the existing gap on efficiency issues (energy balance and losses), social acceptance, and how to best adress the technical obstacles concerning the Underground Thermal Energy Storage (UTES) technologies themselves (high complexity of geological configurations forcing different approaches to the issue) or how to integrate renewable energy sources (e.g. geothermal, solar, thermal, …) with UTES technologies .
Geological media are a strategic resource for the forthcoming energy transition and constitute an important ally in the fight to mitigate the adverse effects of climate change. Several energy and environmental processes in the subsurface involve multi-physical interactions between the porous and fractured rock, and the fluids filling the voids: changes in pore pressure and temperature, rock deformation and chemical reactions occur simultaneously and impact each other. This characteristic has profound implications on the energy production and the waste storage. Forecasts are bounded to the adequate understanding of field data associated with thermo-hydro-mechanical-chemical (THMC) processes and predictive capabilities heavily rely on the quality of the integration between the input data (laboratory and field evidence) and the mathematical models describing the evolution of the multi-physical systems. This session is dedicated to studies investigating THMC problems by means of experimental, analytical, numerical, multi-scale, data-driven and artificial intelligence methods, as well as studies focused on laboratory characterization and on gathering and interpreting in-situ geological and geophysical evidence of the multi-physical behavior of rocks. Welcomed contributions include approaches covering applications of carbon capture and storage (CCS), geothermal systems, gas storage, energy storage, mining, reservoir management, reservoir stimulation, fluid injection-induced seismicity and radioactive waste storage.

Modelling of geological subsurface utilisation in terms of chemical or thermal energy storage as well as hydrocarbon production and storage are required to ensure a safe and sustainable energy supply. Utilisation of the geological subsurface may induce changes in hydraulic, thermal, mechanical and chemical regimes, which need to be assessed using modern geological and reservoir modelling. Our session aims at the integration of experimental and numerical modelling methods for quantification and prediction of the potential impacts resulting from geological subsurface utilisation including:
• Site characterisation and determination of site-specific geological and process data.
• Development of static geological models.
• Integration of experimental data into static and dynamic models as well as application of numerical models for experimental design and interpretation.
• Development and benchmarking of modelling tools.
• Model and parameter upscaling techniques.
• Model coupling addressing the interaction of thermal, multi-phase flow, geochemical and geomechanical processes in the fluid-rock system.
• Application of modelling tools for site characterisation and prediction of potential impacts.
• Methods for risk assessment and efficient site operation.

Reservoir stimulation has been widely applied for extracting geo-energy resources worldwide, e.g., conventional/unconventional oil and gas, as well as geothermal energy. Although it is a critical technology to the development of those geo-energy resources, it is seen critical because of its potential environmental impacts, e.g., consuming a large amount of water, and potentially inducing earthquakes and polluting water in the subsurface and at the earth’s surface. Environmental impacts related to geo-energy production include short-term or long-term air pollution (e.g., CH4/CO2 emission), water pollution, solid waste disposal, and direct or indirect earth’s surface damage. These issues are increasingly becoming the focus of society, in particular under the context of boosting the development of clean energy.
This session will consider the latest advances in reservoir stimulation in geo-energy projects and provide new insights concerning the environmental impacts related to geo-energy production. Abstracts dedicated to the following domains are welcome: (1) integrated geological/engineering technology for reservoir stimulation; (2) fraccability evaluation of geo-energy reservoirs; (3) the development of hydraulic fracturing technologies; (4) the potential use of alternative fracturing fluids, i.e., supercritical CO2, N2, and foam fracturing; (5) big data and AI applications focused on reservoir stimulation; (6) fracturing efficiency; (7) induced seismic and micro-seismic monitoring of fracturing operations; (8) direct and indirect environmental impacts related to the production of any geo-energy resource, e.g. water pollution, CH4/CO2 emission, solid waste disposal.
Contributions based on laboratory experiments, field tests and case studies, numerical simulations and other modelling techniques are equally welcome.
Recently, there have been significant breakthroughs in the use of fiber-optic sensing techniques to interrogate cables at high precision both on land and at sea as well as in boreholes and at the surface. Laser reflectometry using both fit-to-purpose and commercial fiber-optic cables have successfully detected a variety of signals including microseism, local and teleseismic earthquakes, volcanic events, ocean dynamics, etc. Other laser-based techniques can be used to monitor distributed strain, temperature, and even chemicals at a scale and to an extent previously unattainable with conventional geophysical methods.
We welcome any contributions to recent development in the fields of applications, instrumentation, and theoretical advances for geophysics with fiber-optic sensing techniques. These may include - but are not limited to - application of fiber-optic cables or sensors in seismology, geodesy, geophysics, natural hazards, oceanography, urban environment, geothermal application, etc. with an emphasis on laboratory studies, large-scale field tests, and modeling. We also encourage contributions on data analysis techniques, machine learning, data management, instruments performances and comparisons as well as new experimental field studies.
Geomechanics has been demonstrated over the past 30 years as having key importance for the safe and sustainable usage of underground environments. In particular, knowledge of geomechanics is critical for exploration and production of geothermal energy, groundwater, hydrocarbon, and mineral resources. Geomechanics play the central role in any underground storage (such as natural gas, CO2 and H2) and disposal of nuclear or toxic waste. The main goal of this session is therefore to bring together researchers from various engineering and geo-disciplines to share their knowledge in recent advancements in experimental, numerical, theoretical and field application of geomechanics. A particular focus is on the large uncertainties that are often associated with geomechanical measurements or models. In addition to abstracts that exclusively aim at uncertainty quantification and/or reduction at least a discussion of uncertainties is encouraged in every abstract.

Big data analytics will have a primary role in addressing modern challenges such as climate change, disaster management, public health and safety, resources management, and logistics. Most of these phenomena are characterized by spatio-temporal patterns that have been traditionally investigated using linear statistical approaches, as in the case of physically-based models and geostatistical models. Additionally, the rising attention toward machine learning, the variety of modern technologies generating massive volumes of geospatial data at local and global scales, and the rapid growth of computational resources, open new horizons in understanding, modelling, and forecasting complex spatio-temporal systems using stochastics non-linear models.
This session aims at exploring the new challenges and opportunities opened by the spread of big geospatial datasets and data-driven statistical learning approaches in Earth and Soil Sciences. We invite cutting-edge contributions related to methods of spatio-temporal geostatistics or data mining on topics that include, but are not limited to:
- advances in spatio-temporal modeling using geostatistics and machine learning;
- software and infrastructure development for geospatial data;
- uncertainty quantification and representation;
- innovative techniques of knowledge extraction based on clustering, pattern recognition and, more generally, data mining.
The main applications will be closely related to the research in environmental sciences and quantitative geography. A non-complete list of possible applications includes:
- natural and anthropogenic hazards (e.g. floods; landslides; earthquakes; wildfires; soil, water, and air pollution);
- interaction between geosphere and anthroposphere (e.g. land degradation; urban sprawl);
- socio-economic sciences, characterized by the spatial and temporal dimension of the data (e.g. public health management, census data; transport; commuter traffic).
This session collects the abstract submitted to the session “Strategies and Applications of AI and ML in a Spatiotemporal Context” and “Spatio-temporal Data Science: Theoretical Advances and Applications in Computational Geosciences”.

Remote sensing techniques, such as radar (e.g., synthetic aperture radar - SAR), optical, Lidar and hyperspectral imagery, together with hydroclimatic, geological, and geophysical data, as well as in-situ observations, have been widely employed for monitoring, and responding to natural and anthropogenic hazards and assessing environmental resources. Especially with the unprecedented spatio-temporal resolution and the rapid accumulation of remote sensing data collections from various spaceborne and airborne missions, we have much more opportunities to exploit hazard- and environmental- related signals, to classify the associated spatio-temporal surface changes such as deformations and landform alterations, and to interpret the primary and secondary driving mechanisms. Yet, when archiving, processing, and analyzing abundant remote sensing data, the ad hoc artificial intelligence (AI), like machine/deep learning and computer vision, is urgently required.
In this session, we welcome contributions that focus on new AI-based algorithms to retrieve remote sensing products related to environmental resources and hazards in an accurate, automated, and efficient framework. We particularly welcome contributions for applications in (1) mining, oil/gas production, fluid injection/extraction, civil infrastructure, sinkholes, land degradation, peatlands, glaciers, permafrost, and coastal subsidence; (2) emergency response based on remote sensing data to landslides, floods, winter storms, wildfires, pandemics, earthquakes, and volcanoes; and (3) mathematical and physical modeling of the remote sensing products for a better understanding on the surface and subsurface processes.

Machine learning, artificial intelligence and big data approaches have recently emerged as key tools in understanding the cryosphere. These approaches are being increasingly applied to answer long standing questions in cryospheric science, including those relating to remote sensing, forecasting, and improving process understanding across Antarctic, Arctic and Alpine regions. In doing so, data science and AI techniques are being used to gain insight into system complexity, analyse data on unprecedented temporal and spatial scales, and explore much wider parameter spaces than were previously possible.
In this session we invite submissions that utilise data science and/or AI techniques that address research questions relating to glaciology, sea ice, permafrost and/or polar climate science. Approaches used may include (but are not limited to) machine learning, artificial intelligence, big data processing/automation techniques, advanced statistics, and innovative software/computing solutions. These could be applied to any (or combinations) of data sources including remote sensing, numerical model output and field/lab observations. We particularly invite contributions that apply techniques and approaches that reveal new insights into cryospheric research problems that would not otherwise be achievable using traditional methods, and those that discuss how or if approaches can be applied or adapted to other areas of cryospheric science. Given the rapid development of this field by a diverse group of international researchers, we convene this session to help foster future collaboration amongst session contributors, attendees, and international stakeholders and help address the most challenging questions in cryospheric science.

Proper characterization of uncertainty remains a major research and operational challenge in Environmental Sciences, and is inherent to many aspects of modelling impacting model structure development; parameter estimation; an adequate representation of the data (inputs data and data used to evaluate the models); initial and boundary conditions; and hypothesis testing. To address this challenge, methods for a) uncertainty analysis (UA) that seek to identify, quantify and reduce the different sources of uncertainty, as well as propagating them through a system/model, and b) the closely-related methods for sensitivity analysis (SA) that evaluate the role and significance of uncertain factors (in the functioning of systems/models), have proved to be very helpful.
This session invites contributions that discuss advances, both in theory and/or application, in methods for SA/UA applicable to all Earth and Environmental Systems Models (EESMs), which embraces all areas of hydrology, such as classical hydrology, subsurface hydrology and soil science.
Topics of interest include (but are not limited to):
1) Novel methods for effective characterization of sensitivity and uncertainty
2) Analyses of over-parameterised models enabled by AI/ML techniques
3) Single- versus multi-criteria SA/UA
4) Novel approaches for parameter estimation, data inversion and data assimilation
5) Novel methods for spatial and temporal evaluation/analysis of models
6) The role of information and error on SA/UA (e.g., input/output data error, model structure error, parametric error, regionalization error in environments with no data etc.)
7) The role of SA in evaluating model consistency and reliability
8) Novel approaches and benchmarking efforts for parameter estimation
9) Improving the computational efficiency of SA/UA (efficient sampling, surrogate modelling, parallel computing, model pre-emption, model ensembles, etc.)
This Short Course is aimed at researchers in climate-related domains, who have an interest in working with climate data. We will introduce the ESMValTool, a Python project developed to facilitate the analysis of climate data through so-called recipes. An ESMValTool recipe specifies which input data will be used, which preprocessor functions will be applied, and which analytics should be computed. As such, it enables readable and reproducible workflows. The tool takes care of finding, downloading, and preparing data for analysis. It includes a suite of preprocessing functions for commonly used operations on the input data, such as regridding or computation of various statistics, as well as a large collection of established analytics.
In this course, we will run some of the available example recipes using ESMValTool’s convenient Jupyter notebook interface. You will learn how to customize the examples, in order to get started with implementing your own analysis. A number of core developers of ESMValTool will be present to answer any and all questions you may have.
The ESMValTool has been designed to analyze the data produced by Earth System Models participating in the Coupled Model Intercomparison Project (CMIP), but it also supports commonly used observational and re-analysis climate datasets, such as ERA5. Version 2 of the ESMValTool has been specifically developed to target the increased data volume and complexity of CMIP Phase 6 (CMIP6) datasets. ESMValTool comes with a large number of well-established analytics, such as those in Chapter 9 of the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) (Flato et al., 2013) and has been extensively used in preparing the figures of the Sixth Assessment Report (AR6). In this way, the evaluation of model results can be made more efficient, thereby enabling scientists to focus on developing more innovative methods of analysis rather than constantly having to "reinvent the wheel".

Unsupervised, supervised, semi-supervised as well as reinforcement learning are now increasingly used to address Earth system related challenges.
Machine learning could help extract information from numerous Earth System data, such as in-situ and satellite observations, as well as improve model fidelity through novel parameterisations or speed-ups. This session invites submissions spanning modelling and observational approaches towards providing an overview of the state-of-the-art of application of these novel methods for predicting and monitoring our earth system. This includes (but it is not restricted to):
- the use of machine learning to improve forecast skill
- generate significant speedups
- design new parameterization schemes
- emulate numerical models.
Please consider submitting abstracts focussed on ML applied to observations and modelling of climate processes to the companion "ML for Climate Science" session.
The increasing amount of data from an increasing number of spacecraft in our solar system shouts out for new data analysis strategies. There is a need for frameworks that can rapidly and intelligently extract information from these data sets in a manner useful for scientific analysis. The community is starting to respond to this need. Machine learning, with all of its different facets, provides a viable playground for tackling a wide range of research questions in planetary and heliospheric physics.
We encourage submissions dealing with machine learning approaches of all levels in planetary sciences and heliophysics. The aim of this session is to provide an overview of the current efforts to integrate machine learning technologies into data driven space research, to highlight state-of-the art developments and to generate a wider discussion on further possible applications of machine learning.

Through a wealth of geospatial data, growing computational power, and demonstrated success of application across many fields, artificial intelligence (in particular, machine learning) promises to advance our understanding of natural hazards and our ability to predict and respond to natural disasters. The ITU/WMO/UNEP Focus Group AI for Natural Disaster Management (FG-AI4NDM) is building a community of experts and stakeholders to identify best practices in the use of AI for data processing, improved modeling across spatiotemporal scales, and providing effective communication. This multidisciplinary FG-AI4NDM-session invites contributions addressing challenges related to floods, landslides, earthquakes, volcanic eruptions, tsunamis, among others, as well as multi-hazard. It also welcomes presentations on novel AI methods (including advances in automated annotation, explainability, etc.), which are hazard agnostic.
From the real-time integration of multi-parametric observations is expected the major contribution to the development of operational t-DASH systems suitable for supporting decision makers with continuously updated seismic hazard scenarios. A very preliminary step in this direction is the identification of those parameters (seismological, chemical, physical, biological, etc.) whose space-time dynamics and/or anomalous variability can be, to some extent, associated with the complex process of preparation of major earthquakes.
This session wants then to encourage studies devoted to demonstrate the added value of the introduction of specific, observations and/or data analysis methods within the t-DASH and StEF perspectives. Therefore, studies based on long-term data analyses, including different conditions of seismic activity, are particularly encouraged. Similarly welcome will be the presentation of infrastructures devoted to maintain and further develop our present observational capabilities of earthquake related phenomena also contributing in this way to build a global multi-parametric Earthquakes Observing System (EQuOS) to complement the existing GEOSS initiative.
To this aim this session is not addressed just to seismology and natural hazards scientists but also to geologist, atmospheric sciences and electromagnetism researchers, whose collaboration is particular important for fully understand mechanisms of earthquake preparation and their possible relation with other measurable quantities. For this reason, all contributions devoted to the description of genetic models of earthquake’s precursory phenomena are equally welcome.

Recent developments in machine learning (ML) are transforming Earth observation data analysis and modelling of the Earth system and its constituent processes. While statistical models have been used for a long time, state-of-the-art machine and deep learning algorithms allow encoding non-linear, spatio-temporal relationships robustly without sacrificing interpretability. These advances have the potential to accelerate climate science by improving our understanding of the underlying processes, reducing and better quantifying uncertainty, and even making predictions directly from observations across different spatio-temporal scales.
This session aims to provide a venue to present the latest progress in the use of ML applied to all aspects of climate science including, but not limited to:
- Causal discovery and inference
- Learning (causal) process and feature representations in observations
- Hybrid models (physically informed ML)
- Novel detection and attribution approaches
- Probabilistic modelling and uncertainty quantification
- Explainable AI applications to climate science
Please consider submitting abstracts focussed on ML for model improvement, particularly for near-term (including seasonal) forecasting to the companion “ML for Earth System modelling” session.
Geomorphometry and landform mapping are important tools used for understanding landscape processes and dynamics on Earth and other planetary bodies. The recent rapid advances in technology and data collection methods have made available vast quantities of geospatial data offering unprecedented spatio-temporal range, density, and resolution, but it also created new challenges in terms of data processing and analysis.
This inter-disciplinary session on geomorphometry and landform mapping aims to bridge the gap between process-focused research fields and the technical domain where geospatial products and analytical methods are developed. The increasing availability of a wide range of geospatial datasets requires the continued development of new tools and analytical approaches as well as landform/landscape classifications. However, a potential lack of communication across disciplines results in efforts to be mainly focused on problems within individual fields. We aim to foster collaboration and the sharing of ideas across subject-boundaries, between technique developers and users, enabling us as a community to fully exploit the wealth of geospatial data that is now available.
We welcome perspectives on geomorphometry and landform mapping from ANY discipline (e.g. geomorphology, planetary science, natural hazard assessment, computer science, remote sensing). This session aims to showcase both technical and applied studies, and we welcome contributions that present (a) new techniques for collecting or deriving geospatial data products, (b) novel tools for analysing geospatial data and extracting innovative geomorphometric variables, (c) mapping and/or morphometric analysis of specific landforms as well as whole landscapes, and (d) mapping and/or morphometric analysis of newly available geospatial datasets. Contributions that demonstrate multi-method or inter-disciplinary approaches are particularly encouraged. We also actively encourage contributors to present tools/methods that are “in development”.

Geomorphometry, a science of quantitative land surface analysis, gathers various mathematical, statistical and image processing techniques to quantify morphological, hydrological, ecological and other aspects of a land surface. The typical input to geomorphometric analysis is a square-grid representation of the land surface: a digital elevation model (DEM) or one of its derivatives. DEMs provide the backbone for many studies in Geo sciences, hydrology, land use planning and management, Earth observation and natural hazards.
One topic of active research concerns compromises between the use of global DEMs at 1-3 arc second, ~30-90 m grid spacing, and local LiDAR/structure from motion (SFM) elevation models at 1 m or finer grid spacing. Point clouds from LiDAR, either ground-based or from airborne vehicles, are a generally accepted reference tool to assess the accuracy of other DEMs. SFM data have a resolution comparable to LiDAR point clouds, but can cost significantly less to acquire for smaller areas. Globally available DEMS include the recently published Copernicus GLO-90 and GLO-30. This session provides an exciting forum to show the potential applications of this new DEM and its improvements over SRTM. We would like to investigate the tradeoff between the employment of the two kinds of data, and applications which can benefit from data at both (local and global) scales.
The improvements in the global DEMs, as well as the increasing availability of much finer resolution LiDAR and SFM DEMs, call for new analytical methods and advanced geo-computation techniques, necessary to cope with diverse application contexts. We aim at investigating new methods of analysis and advanced geo-computation techniques, including high-performance and parallel computing implementations of specific approaches.
Commercial applications of DEM data and of geomorphometric techniques can benefit important business sectors. Besides a proliferation of applications that can tolerate low accuracy geographical data and simple GIS applications, a large base of professionals use high-resolution, high-accuracy elevation data and high-performance GIS processing. We would like to survey and investigate professional, commercial and industrial applications, including software packages, from small enterprises to large companies, to ascertain how academic researchers and industry can work together.
As we increasingly face global challenges such as climate change, pandemics, environmentally sustainable exploitation of our resources, there is a greater urgency to bring together multiple existing data/information infrastructure systems that are distributed around the world to create machine actionable, interoperable, reusable, real-time data sharing frameworks.
The problem is that research can be a ‘competitive’ process, and there is a tendency for this competition to be focused on which is considered to be the best data sharing system or data standard that supposedly is THE one that everyone SHOULD use.
An alternative approach is to build loosely coupled frameworks that allow multiple existing systems to interoperate, but still, preserve their deeper disciplinary specialization. For this approach to work, there will need to be agreement on 1) the minimum core variables for sharing data content, and 2) the technical standards/technologies required to enable real-time data interoperability.
There are well-established examples of groups facilitating global data sharing (e.g., Federation of Digital Seismograph Networks (FDSN), OneGeology, Earth Systems Grid Federation (ESFG), OGC, W3C, GEO). Many new groups are starting to form global disciplinary data networks: some are already trying to link frameworks together to enable global interdisciplinary sharing of data (e.g., CODATA/DDI Cross-Domain Data Initiative).
This session seeks contributions from any group that has established or is establishing a data-sharing infrastructure system/framework regardless of scale, as well as those that are attempting global and/or interdisciplinary networking. Topics may range from (meta)data standards, defining minimum core content variables, or be focused on technologies or organizational setups for enabling data sharing. Papers on the social dynamics of building sharing systems/frameworks are also welcome.

Current pre-exascale computing systems, and the strong push towards exascale warrant substantial efforts to improve the geoscientific software infrastructure used for Earth System Model (ESM) development, data analysis, and storage. The Exascale era opens a range of opportunities, including increased domain size, simulation duration, model resolution, large ensembles, and new physics. This session will discuss challenges and solutions involving domain scientists, applied mathematicians, computer scientists, HPC, and compression experts.
Contributions address challenges and advances to achieve exascale-readiness geoscience disciplines, methods, and technologies.
Pangeo (pangeo.io) is a community of researchers and developers that tackle these issues in a collaborative manner using a growing Python ecosystem whose core tools include xarray, Iris, DASK, Jupyter, Zarr and INTAKE. Many contributors to this session will share novel tools within the Pangeo ecosystem devoted to Atmosphere, Ocean and Land Models, Satellite Observations, HPC, Cloud computing, Machine Learning, and Scalable scientific computing.
This session also considers how geoscientists can shift towards greener computing by adopting modern data compression techniques including, though not limited to: algorithmic advances, assessments of data storage sustainability, compression efficiency and speed in software and/or hardware, interoperability issues, remote sensing applications, and support in widely used languages (e.g., C/C++, Fortran, Java, Python), data storage formats (e.g., HDF, netCDF, Zarr), and Open Source workflows (e.g., CDO, NCO, Pangeo, Ruby, Xarray).
All authors in this session have the option to submit Jupyter notebooks of their work; the best five will be selected as part of the Pangeo applications gallery of EGU22. Examples of previous galleries are at http://gallery.pangeo.io.

In many scientific disciplines, accurate, intuitive, and aesthetically pleasing display of geospatial information is a critical tool. PyGMT (https://www.pygmt.org) - a Python interface to the Generic Mapping Tools (GMT) - is a mapping toolbox designed to produce publication-quality figures and maps for insertion into posters, reports, and manuscripts. This short course is geared towards geoscientists interested in creating beautiful maps using Python. Only basic Python knowledge is needed, and a background in cartography is not required to use PyGMT effectively! By the end of this tutorial, students will be able to:
- Craft basic maps with geographic map frames using different projections
- Add context to their figures, such as legends, colorbars, and inset overview maps
- Use PyGMT to process PyData data structures (xarray/pandas/geopandas) and plot them on maps
- Understand how PyGMT can be used for various applications in the Earth sciences and beyond!
The 1.5 hour long short course will be based on content adapted from https://github.com/GenericMappingTools/2021-unavco-course and https://github.com/GenericMappingTools/foss4g2019oceania. Each of the 30 minute sessions will involve a quick (~10 minute) walkthrough by the speaker, followed by a more hands-on session in breakout rooms where tutorial participants work on the topic (using interactive Jupyter notebooks) in a guided environment with one of four instructors on hand to answer questions.
We expressly welcome students and geoscientists working on any geo related fields (e.g. Earth Observation, Geophysical, Marine, Magnetic, Gravity, Planetary, etc) to join. Come and find out what PyGMT can do to level up your geoprocessing workflow!

As funders and publishers increasingly require that research data be made publicly available, research data repositories, especially in the Earth and environmental sciences, play a new and major role in the publication process. They are on one hand supporting researchers during the data publication process and, on the other hand, need to present the data in a way that they are fully integrable in the ecosystem of modern scientific communication as required by the FAIR Data Principles. More recent developments, like the CoreTrustSeal Certification and the Enabling FAIR Data Commitment Statement have defined additional benchmarks and expectations for the capabilities of repositories.
How do repositories comply with increasing expectations for machine accessibility of their data and the requirements for machine learning (particularly for long tail data)? How do researchers know which repositories meet these benchmarks and future expectations? How should publishers work together with repositories and researchers to ensure a more complete record of science? What role can data journals and editors play?
This session will showcase the range of practices in research data repositories, data publication and the integration of data, software, samples, models and notebooks into the scholarly publication process. It invites repositories, researchers, information scientists, journals, and editors to discuss challenges they are facing in meeting community best practice.
Globally, geoscience and research analytical laboratories collect ever increasing volumes of data: an acute challenge now is how to collate, store and make these data accessible in a standardised, interoperable and machine-accessible form that is FAIR. Many solutions today are bespoke and inefficient, lacking, for example, unique identification of samples, instruments, and data sets needed to trace the analytical history of the data; and there are few community agreed standards to facilitate sharing and interoperability between systems.
The push for a solution is being driven by publishers and journals who increasingly require researchers to provide access to the supporting data from a trusted repository prior to publication of manuscripts or finalisation of grants. We urgently need community development of systems to facilitate easy and efficient management of geoanalytical laboratory data. We need to address the lack of global standards, best practices and protocols for analytical data management and exchange, in order for scientists to better share their data in a global network of distributed databases. Buy-in from users and laboratory managers/technicians is essential in order to develop efficient and supported mechanisms.
This session seeks a diversity of papers from any initiative around the world that organises and structures sample/field metadata and research laboratory data at any scale to facilitate sharing and processing of geoanalytical data. We welcome papers on data and metadata standardisation efforts and papers on data management and systems that transfer data/metadata from instruments to shared data systems and relevant persistent repositories. Efforts on how to collate, curate, share and publicise sample/data collections as well as papers on the social dynamics of building sharing systems/frameworks are also welcome.

Earth science research has become increasingly collaborative through shared code and shared platforms. Researchers work together on data, software and algorithms to answer cutting-edge research questions. Teams also share these data and software with other collaborators to refine and improve these products. This work is supported by Free and Open Source Software (FOSS) and by shared virtual research infrastructures utilising cloud and high-performance computing.
Software is critical to the success of science. Creating and using FOSS enhances collaboration and innovation in the scientific community, creates a peer-reviewed and consensus-oriented environment, and promotes the sustainability of science infrastructures.
This session will showcase solutions and applications based on the Free and Open Source Software (FOSS), cloud-based architecture and high-performance computing to support information sharing, scientific collaboration, and solutions that enable large-scale data analytics at scale solutions.

Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

One of today's challenges in the Earth sciences is the continuous evolution of technologies, making it hard for users and developers to be up to date and take advantage of the most advanced solutions.
On the other hand, there have never been such favorable conditions for the development of Earth observation based services and applications targeting both public and private sector.
For this session we invite abstracts that present operational applications for scientific services across the geosciences, including ocean research, forest monitoring, crop monitoring and more. By presenting these success stories we hope to initiate a discussion between different actors involved in making and using services addressing gaps and needs for faster uptake of Earth observation based services.

Environmental systems often span spatial and temporal scales covering different orders of magnitude. The session is oriented toward collecting studies relevant to understand multiscale aspects of these systems and in proposing adequate multi-platform and inter-disciplinary surveillance networks monitoring tools systems. It is especially aimed to emphasize the interaction between environmental processes occurring at different scales. In particular, special attention is devoted to the studies focused on the development of new techniques and integrated instrumentation for multiscale monitoring of high natural risk areas, such as volcanic, seismic, energy exploitation, slope instability, floods, coastal instability, climate changes, and another environmental context.
We expect contributions derived from several disciplines, such as applied geophysics, geology, seismology, geodesy, geochemistry, remote and proximal sensing, volcanology, geotechnical, soil science, marine geology, oceanography, climatology, and meteorology. In this context, the contributions in analytical and numerical modeling of geological and environmental processes are also expected.
Finally, we stress that the inter-disciplinary studies that highlight the multiscale properties of natural processes analyzed and monitored by using several methodologies are welcome.

Remote sensing measurements, acquired using different platforms - ground, UAV, aircraft and satellite - have increasingly become rapidly developing technologies to study and monitor Earth surface, to perform comprehensive analysis and modeling, with the final goal of supporting decision systems for ecosystem management. The spectral, spatial and temporal resolutions of remote sensors have been continuously improving, making environmental remote sensing more accurate and comprehensive than ever before. Such progress enables understanding of multiscale aspects of high-risk natural phenomena and development of multi-platform and inter-disciplinary surveillance monitoring tools. The session welcomes contributions focusing on present and future perspectives in environmental remote sensing, from multispectral/hyperspectral optical and thermal sensors. Applications are encouraged to cover, but not limited to, the monitoring and characterization of environmental changes and natural hazards from volcanic and seismic processes, landslides, and soil science. Specifically, we are looking for novel solutions and approaches including the topics as follows: (i) state-of-the-art techniques focusing on novel quantitative methods; (ii) new applications for state-of-the-art sensors, including UAVs and other close-range systems; (iii) techniques for multiplatform data fusion.
Detailed seabed maps portraying the distribution of geomorphic features, substrates, and habitats are used for a wide range of scientific, maritime industry, and government applications. These maps provide essential information for ocean industry sectors and are used to guide local and regional conservation action. Fundamental to seabed mapping are acoustic remote sensing technologies, including single beam and multibeam echosounders and sidescan, interferometric, and synthetic-aperture sonars. These are deployed on a variety of crewed and robotic surface and underwater platforms. In shallow clear waters, optical sensors including LiDAR, multispectral, and hyperspectral cameras are also increasingly employed from aircraft, drones, and satellites to create maps of the seabed. Innovative data processing, image analysis, and statistical approaches for classification are advancing the field of seabed mapping. These methods are yielding increasingly comprehensive and detailed maps. We welcome submissions that provide insights into the use of advanced technologies, novel processing and analytical approaches, and current and emerging applications in the field of seabed mapping and classification – from shallow coastal waters to the deep seafloor.

Continues monitoring of infrastructure systems are essential to ensure a reliable movement of people and goods, which involves in the economy growth and human interaction. The wide variety of instruments available allows diverse applications to increase data availability for a better understanding of geotechnical surroundings which are directly linked to the safe operation of infrastructures to prevent catastrophise such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding and even wildfires close to the highways. Understanding mentioned events are vital to provide a safe infrastructure in extreme climate conditions. This session focus on the application of geosciences and geophysical instrumentation including sensors on the infrastructures monitoring and data analysis from critical infrastructures (e.g., roadways, railway system, bridges, tunnels, water supply, underground utilities, electrical grids, and other embedded facilities in cities). The session aims to increase knowledge on geo-infrastructure management to overcome future challenges associated with the societal and human interaction, present advance knowledge research and novel approaches from various disciplines with a vibrant interaction to economy and human-interaction studies to provide an efficient infrastructure management system. The session is considered inter-and transdisciplinary (ITS) session. The applications and topics include but are not limited to: (1) Advance knowledge of the destructive and non-destructive geoscience and geophysical techniques including contactless and non-contactless techniques such as sensors. (2) Intelligent data analysis approaches to analyse accurate and precise interpretation of big data sets driven from various technologies (e.g., computer vision and image, and signal processing). (3) Influence of the surrounding areas on infrastructure management systems linked to natural events such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding, wildfires and extreme weather condition. (4) Continuous real-time monitoring to provide smart tools such as an integration of geosciences data with BIM models, Internet of Things, digital twins, robotic monitoring, artificial intelligence, automation systems based on machine learning and computational modelling for better decision-making for infrastructure owner/operators. (5) Human-interaction computer-based aided to generate reliable infrastructures.
Synthetic aperture radar (SAR) remote sensing is an established tool for natural and anthropogenic hazards mapping and monitoring. The new generation of radar satellite constellations along with a consistent repository of historical observations is fostering comprehensive multi-sensor hazard analyses. New constellations’ capabilities rely on innovative techniques based on high-resolution/wide-swath and short-temporal Interferometric SAR (InSAR). While acknowledging the benefits brought by these recent developments, the scientific community is now defining a new paradigm of techniques capable of: extracting relevant information from SAR imagery, designing proper methodologies for specific hazards, managing large SAR datasets (e.g. National ground motion services, Copernicus EGMS), and integrating radar data with multispectral satellite observations.

Remote sensing and Earth Observations (EO) are used increasingly in the different phases of the risk management and in development cooperation, due to the challenges posed by contemporary issues such as climate change, and increasingly complex social interactions. The advent of new, more powerful sensors and more finely tuned detection algorithms provide the opportunity to assess and quantify natural hazards, their consequences, and vulnerable regions, more comprehensively than ever before.
Several agencies have now inserted permanently into their program the applications of EO data to risk management. During the preparedness and prevention phase, EO revealed, fundamental for hazard, vulnerability, and risk mapping. EO data intervenes both in the emergency forecast and early emergency response, thanks to the potential of rapid mapping. EO data is also increasingly being used for mapping useful information for planning interventions in the recovery phase, and then providing the assessment and analysis of natural hazards, from small to large regions around the globe. In this framework, Committee on Earth Observation Satellites (CEOS) has been working from several years on disasters management related to natural hazards (e.g., volcanic, seismic, landslide and flooding ones), including pilots, demonstrators, recovery observatory concepts, Geohazard Supersites, and Natural Laboratory (GSNL) initiatives and multi-hazard management projects.
The session is dedicated to multidisciplinary contributions focused on the demonstration of the benefit of the use of EO for natural hazards and risk management.
The research presented might focus on:
- Addressed value of EO data in hazard/risk forecasting models
- Innovative applications of EO data for rapid hazard, vulnerability and risk mapping, the post-disaster recovery phase, and in support of disaster risk reduction strategies
- Development of tools for assessment and validation of hazard/risk models
The use of different types of remote sensing (e.g. thermal, visual, radar, laser, and/or the fusion of these) is highly recommended, with an evaluation of their respective pros and cons focusing also on future opportunities (e.g. new sensors, new algorithms).
Early-stage researchers are strongly encouraged to present their research. Moreover, contributions from international cooperation, such as CEOS and GEO initiatives, are welcome.

The session gathers geoscientific aspects such as dynamics, reactions, and environmental/health consequences of radioactive materials that are massively released accidentally (e.g., Chernobyl and Fukushima nuclear power plant accidents, wide fires, etc.) and by other human activities (e.g., nuclear tests).
The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Thus, the radioactive contamination problem is multi-disciplinary. In fact, this topic involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic and ecosystem, and its relations with human and non-human biota. The topic also involves hazard prediction and nowcast technology.
By combining 35 years (> halftime of Cesium 137) monitoring data after the Chernobyl Accident in 1986, 10 years dense measurement data by the most advanced instrumentation after the Fukushima Accident in 2011, and other events, we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents.
The following specific topics have traditionally been discussed:
(a) Atmospheric Science (emissions, transport, deposition, pollution);
(b) Hydrology (transport in surface and ground water system, soil-water interactions);
(c) Oceanology (transport, bio-system interaction);
(d) Soil System (transport, chemical interaction, transfer to organic system);
(e) Forestry;
(f) Natural Hazards (warning systems, health risk assessments, geophysical variability);
(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).
The session consists of updated observations, new theoretical developments including simulations, and improved methods or tools which could improve observation and prediction capabilities during eventual future nuclear emergencies. New evaluations of existing tools, past nuclear contamination events and other data sets also welcome.

Non-destructive testing (NDT) methods are employed in a variety of engineering and geosciences applications and their stand-alone use has been greatly investigated to date. New theoretical developments, technological advances and the progress achieved in surveying, data processing and interpretation have in fact led to a tremendous growth of the equipment reliability, allowing outstanding data quality and accuracy.
Nevertheless, the requirements of comprehensive site and material investigations may be complex and time-consuming, involving multiple expertise and multiple equipment. The challenge is to step forward and provide an effective integration between data outputs with different physical quantities, scale domains and resolutions. In this regard, enormous development opportunities relating to data fusion, integration and correlation between different NDT methods and theories are to be further investigated.
This Session primarily aims at disseminating contributions from state-of-the-art NDT methods and new numerical developments, promoting the integration of existing equipment and the development of new algorithms, surveying techniques, methods and prototypes for effective monitoring and diagnostics. NDT techniques of interest are related–but not limited to–the application of acoustic emission (AE) testing, electromagnetic testing (ET), ground penetrating radar (GPR), geoelectric methods (GM), laser testing methods (LM), magnetic flux leakage (MFL), microwave testing, magnetic particle testing (MT), neutron radiographic testing (NR), radiographic testing (RT), thermal/infrared testing (IRT), ultrasonic testing (UT), seismic methods (SM), vibration analysis (VA), visual and optical testing (VT/OT).
The Session will focus on the application of different NDT methods and theories and will be related –but not limited to– the following investigation areas:
- advanced data fusion;
- advanced interpretation methods;
- design and development of new surveying equipment and prototypes;
- real-time and remote assessment and monitoring methods for material and site inspection (real-life and virtual reality);
- comprehensive and inclusive information data systems for the investigation of survey sites and materials;
- numerical simulation and modelling of data outputs with different physical quantities, scale domains and resolutions;
- advances in NDT methods, numerical developments and applications (stand-alone use of existing and state-of-the-art NDTs).
The virus is still with us, with more potent variants. It remains the most immediate challenge for geosciences and health, including its impacts on geoscience development (data collection, training, dissemination) and the achievement of the UN Sustainable Development Goals, in particular that urban systems should increase well-being and health.
Long-term visions based on transdisciplinary scientific advances are therefore essential. As a consequence, this session, like the ITS1.1 session in 2021, calls for contributions based on data-driven and theory-based approaches to health in the context of global change. This includes :
- main lessons from lockdowns?
- how to get the best scientific results during a corona pandemic?
- how to manage field works, geophysical monitoring and planetary missions?
- qualitative improvements in epidemic modelling, with nonlinear, stochastic, and complex system science approaches;
- eventual interactions between weather and/or climate factors and epidemic/health problems
- new surveillance capabilities (including contact tracing), data access, assimilation and multidimensional analysis techniques;
- a fundamental revision of our urban systems, their greening and their need for mobility;
- a special focus on urban biodiversity, especially to better manage virus vectors;
- urban resilience must include resilience to epidemics, and therefore requires revisions of urban governance.

The analysis of the Earth's gravity and magnetic fields is becoming increasingly important in geosciences. Modern satellite missions are continuing to provide data with ever improving accuracy and nearly global, time-dependent coverage. The gravitational field plays an important role in climate research, as a record of and reference for the observation of mass transport. The study of the Earth's magnetic field and its temporal variations is yielding new insights into the behavior of its internal and external sources. Both gravity and magnetic data furthermore constitute primary sources of information also for the global characterization of other planets. Hence, there continues to be a need to develop new methods of analysis, at the global and local scales, and especially on their interface. For over two decades now, methods that combine global with local sensitivity, often in a multiresolution setting, have been developed: these include wavelets, radial basis functions, Slepian functions, splines, spherical cap harmonics, etc. One purpose of this session is to provide a forum for exchange of research projects, whether related to forward or inverse modeling, theoretical, computational, or observational studies.
Besides monitoring the variations of the gravity and magnetic fields, space geodetic techniques deliver time series describing changes of the surface geometry, sea level change variations or fluctuations in the Earth's orientation. However, geodetic observation systems usually measure the integral effect. Thus, analysis methods have to be applied to the geodetic time series for a better understanding of the relations between and within the components of the system Earth. The combination of data from various space geodetic and remote sensing techniques may allow for separating the integral measurements into individual contributions of the Earth system components. Presentations to time frequency analysis, to the detection of features of the temporal or spatial variability of signals existing in geodetic data and in geophysical models, as well as to the investigations on signal separation techniques, e.g. EOF, are highly appreciated. We further solicit papers on different prediction techniques e.g. least-squares, neural networks, Kalman filter or uni- or multivariate autoregressive methods to forecast Earth Orientation Parameters, which are needed for real-time transformation between celestial and terrestrial reference frames.

In recent years we have witnessed a remarkable progress in terms of signals, services and satellite deployment of Global Navigation Satellite Systems (GNSS). The modernisation of fully operational GNSS systems and the development of new constellations, have seen us move towards a new stage of multi-constellation and multi-frequency observations. Meanwhile, the huge technology development provided high-grade GNSS equipment able to collect measurements at much higher rates, up to 100 Hz, hence opening new possibilities. Moreover, the recent progress in low-cost GNSS chipsets is catalyzing an expansion of traditional satellite navigation to novel areas of science and industry.
Therefore, on one side, the new developments in GNSS stimulate a broad range of new applications for solid and fluid Earth investigations, both in post-processing and in real-time; on the other side, this results in new problems and challenges in data processing which boost GNSS research. Algorithmic advancements are needed to address the opportunities and challenges in enhancing the accuracy, availability, interoperability and integrity of high-precision GNSS applications.
This session is a forum to discuss new developments in high-precision GNSS algorithms and applications in Geosciences; in this respect, contributions from other branches in Geosciences (geodynamics, seismology, tsunamis, ionosphere, troposphere, etc.) are very welcome.
We encourage, but not limit, submissions related to:
- Processing algorithms in high-precision GNSS,
- Multi-GNSS benefit for Geosciences,
- Multi-GNSS processing and product standards,
- Inter-system and inter-frequency biases,
- GNSS products for high-precision applications (orbits, clocks, UPDs, etc.),
- Precise Point Positioning (PPP, PPP-RTK) and Real Time Kinematic (RTK),
- High-rate GNSS,
- Low-cost receiver and smartphone GNSS observations for precise positioning, navigation and geoscience applications,
- GNSS and other sensors (accelerometers, INS, etc.) integration for high-rate applications,
- Troposphere and ionosphere modelling in GNSS positioning and applications,
- CORS services for Geosciences (GBAS, Network-RTK, etc.),

This session aims to showcase novel applications of data science and machine learning methods in geodesy.
In recent years, the amount of data from geodetic observation techniques has increased dramatically. Innovative approaches are required to efficiently handle and harness the vast amount of geodetic data available nowadays for scientific purposes. In particular, Global Navigation Satellite System (GNSS) and Interferometric Synthetic Aperture Radar (InSAR) are facing challenges, but also opportunities, related to the expansive data collection (“big data”). Similarly, numerical weather models and other geophysical models important for geodesy come with ever growing resolutions and dimensions. Strategies and methodologies from the fields of data science and machine learning have shown great potential not only in this context, but also when applied to more limited data sets to solve complex non-linear problems in geodesy.
We invite contributions related to various aspects of applying methods from data science and machine learning (including both shallow and deep learning techniques) to geodetic problems and data sets. We welcome investigations related to (but not limited to): more efficient and automated processing of geodetic data, pattern and anomaly detection in geodetic time series, images or higher-dimensional data sets, improved predictions of geodetic parameters into the future, combination and extraction of information from multiple inhomogeneous data sets (multi-temporal, multi-sensor, multi-modal fusion), feature selection, super-sampling of geodetic data, and improvements of large-scale simulations. Especially encouraged are contributions that discuss the uncertainty quantification, interpretability and explainability of results from machine learning algorithms, as well as the integration of physical modeling into data-driven frameworks.

Remarkable advances over recent years give an evidence that geodesy today develops under a broad spectrum of interactions, including theory, science, engineering, technology, observation, and practice-oriented services. Geodetic science accumulates significant results in studies towards classical geodetic problems and also problems that only emerged or gained new interest, in many cases as a consequence of synergistic activities in geodesy and tremendous advances in the instrumentations and computational facilities. In-depth studies progressed in parallel with investigations that mean a broadening of the traditional core of geodesy. The scope of the session is conceived with a certain degree of freedom, though the session is primarily intended to provide a forum for all investigations and results of theoretical and methodological nature.
Within this concept we seek contributions concerning problems of reference frames, gravity field studies, dynamics and rotation of the Earth, positioning, but also presentations, which surpass frontiers of these topics. We invite presentations illustrating the use of mathematical and numerical methods in solving geodetic problems, showing advances in mathematical modeling, estimating parameters, simulating relations and systems, using high-performance computations, and discussing also methods that enable to exploit data essentially associated with new and existing satellite missions. Presentations showing mathematical and physical research directly motivated by geodetic need, practice and ties to other disciplines are welcome. In parallel to theory oriented results also examples illustrating the use of new methods on real data in various branches of geodetic science and practice are very much solicited in this session.

Precise orbit determination is of central importance for many applications of geodesy and earth science. The challenge is to determine satellite orbits in an absolute sense at the centimeter or even sub-centimeter level, and at the millimeter or even sub-millimeter level in a relative sense. Four constellations of GNSS satellites are available and numerous position-critical missions (e.g. altimetry, gravity, SAR and SLR missions) are currently in orbit. Altogether, outstanding data are available offering new opportunities to push orbit determination to the limit and to explore new applications.
This session aims to make accessible the technical challenges of orbit determination and modelling to the wider community and to quantify the nature of the impact of dynamics errors on the various applications. Contributions are solicited from, but not limited to, the following areas: (1) precise orbit determination and validation; (2) satellite surface force modelling; (3) advances in modelling atmospheric density and in atmospheric gravity; (4) advances in modelling earth radiation fluxes and their interaction with space vehicles; (5) analysis of changes in geodetic parameters/earth models resulting from improved force modelling/orbit determination methods; (6) improvements in observable modelling for all tracking systems, e.g. SLR, DORIS, GNSS and their impact on orbit determination; (7) advances in combining the different tracking systems for orbit determination; (8) the impact of improved clock modelling methods/space clocks on precise orbit determination; (9) advances in modelling satellite attitude.

The International Terrestrial Reference System (ITRS) and its realizations are nowadays widely used for all applications in geosciences. A new realization, the ITRF2020 is being released, based on the combination of DORIS, GNSS, SLR and VLBI station coordinate time series provided by the IAG/IERS technique services.
The goal of this session is to provide a forum to discuss the following topics:
- Contribution of IAG/IERS technique services;
- Evaluation of state of the art GNSS, VLBI, DORIS and SLR position time series (similar to ITRF2020 input data) and associated datum parameters by comparing them with:
* new coordinate series based on enhanced data modeling strategies or combination at the observation level;
* non-tidal loading displacement models.
- Combination strategy and results using ITRF2020 input data;
- Evaluation of the combined terrestrial reference frames derived with ITRF2020 input data;
- Discrepancies between local ties and space geodesy results. Advanced local tie data acquisition and analysis. Study of station coordinate bias at co-location site;
- Impact of terrestrial reference frame station coordinate modeling (pseudo-periodic signals and post-seismic deformations) on Earth science applications and operational geodetic activities.
Contributions are sought from the individual technique services, space geodetic data analysts, the ITRS combination centres and ITRF users. Methodological and theoretical studies on the use of the ITRS realizations on a global or regional scale are also welcome.
The Global Geodetic Observing System (GGOS) provides measurements of the time varying gravity, rotation, and shape of the Earth using space and terrestrial geodetic techniques. These measurements must be accurate to better than a part per billion in order to advance our understanding of the underlying processes responsible for temporal changes in the Earth's
rotation, gravity, and shape. Demanding applications of geodesy include mass transport in the global water cycle, sea level
and climate change, and crustal deformation associated with geohazards. All these measurements require a common reference with the same precision, like the Terrestrial Reference Frame and the Unified Height System. GGOS is designed to unite the individual observations and model into one consistent frame with the highest precision available to be realized as
Global Geodetic Reference Frame (GGRF). This session welcomes contributions on general GGOS topics, particularly those related to scientific and social aspects of GGOS applications.

This session invites innovative Earth system and climate studies based on geodetic measuring techniques. Modern geodetic observing systems document a wide range of changes in the Earth’s solid and fluid layers at very diverging spatial and temporal scales related to processes as, e.g., glacial isostatic adjustment, the terrestrial water cycle, ocean dynamics and ice-mass balance. Different time spans of observations need to be cross-compared and combined to resolve a wide spectrum of climate-related signals. Geodetic observables are also often compared with geophysical models, which helps to explain observations, evaluate simulations, and finally merge measurements and numerical models via data assimilation.
We appreciate contributions utilizing geodetic data from diverse geodetic satellites including altimetry, gravimetry (CHAMP, GRACE, GOCE and GRACE-FO), navigation satellite systems (GNSS and DORIS) or remote sensing techniques that are based on both passive (i.e., optical and hyperspectral) and active (i.e., SAR) instruments. We welcome studies that cover a wide variety of applications of geodetic measurements and their combination to observe and model Earth system signals in hydrological, ocean, atmospheric, climate and cryospheric sciences. Any new approaches helping to separate and interpret the variety of geophysical signals are equally appreciated. Contributions working towards any of the goals of the Inter-Commission Committee on "Geodesy for Climate Research" (ICCC) of the International Association of Geodesy (IAG) are also welcomed in this session.
With author consent, highlights from this session will be tweeted with a dedicated hashtag during the conference in order to increase the impact of the session.

Satellite altimetry provides the possibility to observe key parts of the hydrosphere, namely the ocean, ice, and continental surface water from space. Since the launch of Topex/Poseidon in 1992, the applications of altimetry have expanded from the open oceans to coastal zones, inland water, land, and sea ice. Today, seven missions are in orbit, providing dense and near-global observations of surface elevation and several other parameters. Satellite altimetry has become an integral part of the global observation of the Earth‘s system and changes therein.
In recent years, new satellite altimetry missions have been launched carrying new instruments; the CryoSat-2/Sentinel-3 missions equipped with a Delay/Doppler altimeter, the Saral AltiKa mission carrying the first Ka-band altimeter, and 2018 launched six beam photon-counting laser altimeter onboard NASAs ICESat-2. Further, new orbits with high inclination and long-repeat time are used for CryoSat-2 and ICESat-2.
Fully exploiting this unprecedented availability of observables will enable new applications and results but also require novel and adapted methods of data analysis.
Across the different applications for satellite altimetry, the data analysis and underlying methods are similar and a knowledge exchange between the disciplines has been proofed to be fruitful.
In this multidisciplinary altimetry session, we therefore invite contributions which discuss new methodology and applications for satellite altimetry in the fields of geodesy, hydrology, cryosphere, oceanography, and climatology.
Topics of such studies could for example be (but not limited to); creation of robust and consistent time series across sensors, validation experiments, combination of radar and laser altimetry for e.g. remote sensing of snow, classification of waveforms, application of data in a geodetic orbit, retracking, or combination with other remote sensing data sets.
Glacial Isostatic Adjustment (GIA) describes the dynamic response of the solid Earth to ice sheet glaciation/deglaciation, which affects the spatial and temporal sea level changes, and induces surface deformation, gravitational field variation and stress changes in the subsurface. The process is influenced by the ice sheet characteristics (e.g., extent, volume, grounding line) and solid Earth structure. With more observational data (e.g., relative sea-level data, GPS data, tide gauges, terrestrial and satellite gravimetry, glacially induced faults) are available/standardized, we can better investigate the interactions between the ice sheets, solid Earth and sea levels, and reveal the ice sheet and sea-level evolution histories and rheological properties of the Earth.
This session invites contributions discussing observations, analysis, and modelling of ice sheet dynamics, solid Earth response, and the resulting global, regional and local sea-level changes and land deformation, including paleo ice sheet and paleo sea-level investigations, geodetic measurements of crustal motion and gravitational change, GIA modelling with complex Earth models (e.g., 3D viscosity, non-linear rheologies) and coupled ice-sheet/Earth modelling, investigations on glacially triggered faulting as well as the Earth’s elastic response to present-day ice mass changes. We also welcome abstracts that address the future ice sheets/shelves evolution and sea-level projection as well as GIA effects on oil migration and nuclear waste repositories. Contributions related to both polar regions and previously glaciated regions are welcomed. This session is co-sponsored by the SCAR sub-committee INSTANT-EIS, Earth - Ice - Sea level, in view of instabilities and thresholds in Antarctica https://www.scar.org/science/instant/home/.
The study of the deformation processes in the interior and boundaries of oceanic and continental plates relies strongly on geodetic surveys. The recent development of dense GNSS networks and Interferometric Synthetic Aperture Radar (InSAR) satellite missions with higher spatio-temporal resolution data, and seafloor geodesy experiments (pressure monitoring, acoustic ranging, GNSS-Acoustic positioning...) has significantly enhanced the level of observations and analysis of numerous active deformation areas, and the understanding of geodynamics of lithospheric plates. Interplate and intraplate tectonic domains may also expose striking examples of crustal deformation including large or moderate earthquakes. Such great wealth of new data allows us to tackle fundamental questions to understand strain-partitioning in present-day active zones, the kinematics of crustal tectonic blocks and its relationship with seismogenic fault sources, and between lithospheric processes and surface deformation. Such new knowledge will be greatly benefited from comparisons with theoretical and experimental models, or joint inversion efforts including sea-land- or space-based geophysical and geochemical surveys.
In this session, we seek contributions using geodetic, geophysical, geologic and seismotectonic data analysis in continental and oceanic active deformation zones, including intraplate volcanic provinces. In particular, studies with multidisciplinary approaches using geodesy, seismology, tectonics and geophysics that bring new constraints on the strain distribution, plate kinematics and lithospheric deformation. Our aim is to discuss new geodetic results and show how they contribute to our understanding of the geodynamics of the lithosphere.

Accurate modeling and prediction of Earth rotation is important for geodesy, astronomy and navigation, and relates to the variability of the circulation of the fluid components of the planet. Over the past years geodetic observation systems have made significant advances in monitoring Earth rotational motion and its variability, which must be accompanied by an enhancement of theories and models.
We are interested in the progress in the theory of Earth rotation. We seek contributions that are consistent internally with the accurate observations at the mm-level, to meet the requirements of Global Geodetic Observing System and respond to IAG Res. 5. We invite presentations within the scope of the IAU/IAG JWG Improving Theories and Models of the Earth’s Rotation.
We welcome contributions that highlight new determinations, analyses, and predictions of Earth Orientation Parameters (EOP), including combinations of different geodetic and astrometric observational techniques for deriving UT1/length-of-day variations and polar motion. We welcome discussions of EOP solutions in conjunction with a consistent determination of terrestrial and celestial frames, as tackled in the IAG/IAU/IERS JWG Consistent Realization of TRF, CRF and EOP. We are particularly interested in results from the current 2nd EOP Prediction Comparison Campaign.
We invite contributions of both the dynamical basis for links between Earth rotation, geophysical fluids, and other geodetic quantities, such as the Earth gravity field or surface deformation, and of explanations for the physical excitations of Earth rotation. Besides tidal influences from outside the Earth, the principal causes for variable EOP appear to be related to angular momentum exchange from variable motions and mass redistribution of the fluid portions of the planet. Observations and analyses of the geophysical fluids (e.g., atmosphere and oceans) have been continually improving over time, and independent observations include the results of gravity missions like GRACE.
We welcome contributions about the relationship between EOP variability and current or potential variability in fluids due to climate variation or global change signals. Forecasts of these quantities are important especially for the operational determination of Earth orientation and the effort to improve predictions is an important topic. We also welcome input on the modeling, variability, and excitations of the rotation of other planetary bodies.

Tides underlie many processes in the ocean, atmosphere and solid Earth, and influence ocean biogeochemistry and ecosystems. They drive ocean mixing, contribute to coastal erosion and sediment transport, and may provide a renewable energy source. Tides influence coastal infrastructure and safe port operations. The severity of storm surge events and coastal flooding is modulated by tides. The relationship between tides and sea ice is also important, not only for sea ice dynamics, but also for transport and mixing processes in the Arctic and Antarctic regions. Interannual variability in the tides may arise from variations in ice extent, changes in ocean stratification or regional climate processes.
Precise knowledge of tides is also necessary for earth observation where the tides are not the main target of study. They play a significant role in determining high-resolution temporal gravity fields from satellite gravimetry as well as sea-level rise estimations from satellite altimetry. Therefore, understanding the evolution of tides from both models and in-situ observations is necessary to understand the implications of tides in current and future climate estimations.
Observations and models of coastal and internal tides continue to develop, as well as their relationships to wind-driven processes and mixing processes. We welcome submissions on observations and models of surface or internal tides in the context of long-term changes in tides, tidal variability, tidal dynamics and the impacts of tides. Submissions are encouraged both from regional and global-scale studies on all aspects of tides.

To address societal concerns over rising sea level and extreme events, understanding the contributions behind these changes is key to predict potential impacts of sea level change on coastal communities and global economy, and is recognized as one of the Grand Challenges of our time by the World Climate Research Programme (WCRP). To continue this discussion, we welcome contributions from the international sea level community that improve our knowledge of the past and present changes in global and regional sea level, extreme events, and flooding, and produce improved predictions of their future changes.
We welcome studies on various drivers of sea level change and linkages between variability in sea level, heat and freshwater content, ocean dynamics, land subsidence from natural versus anthropogenic influences, and mass exchange between the land and the ocean associated with ice sheet and glacier mass loss and changes in the terrestrial water storage. Studies focusing on future sea level changes are also encouraged, as well as those discussing potential short-, medium-, and long-term impacts on coastal and deltaic environments, as well as the global oceans.

The session deals with the documentation and modelling of the tectonic, deformation and geodetic features of any type of volcanic area, on Earth and in the Solar System. The focus is on advancing our understanding on any type of deformation of active and non-active volcanoes, on the associated behaviours, and the implications for hazards. We welcome contributions based on results from fieldwork, remote-sensing studies, geodetic and geophysical measurements, analytical, analogue and numerical simulations, and laboratory studies of volcanic rocks.
Studies may be focused at the regional scale, investigating the tectonic setting responsible for and controlling volcanic activity, both along divergent and convergent plate boundaries, as well in intraplate settings. At a more local scale, all types of surface deformation in volcanic areas are of interest, such as elastic inflation and deflation, or anelastic processes, including caldera and flank collapses. Deeper, sub-volcanic deformation studies, concerning the emplacement of intrusions, as sills, dikes and laccoliths, are most welcome.
We also particularly welcome geophysical data aimed at understanding magmatic processes during volcano unrest. These include geodetic studies obtained mainly through GPS and InSAR, as well as at their modelling to imagine sources.
The session includes, but is not restricted to, the following topics:
volcanism and regional tectonics;
formation of magma chambers, laccoliths, and other intrusions;
dyke and sill propagation, emplacement, and arrest;
earthquakes and eruptions;
caldera collapse, resurgence, and unrest;
flank collapse;
volcano deformation monitoring;
volcano deformation and hazard mitigation;
volcano unrest;
mechanical properties of rocks in volcanic areas.
Long term observations are of vital importance in the Earth Sciences, yet often difficult to pursue and fund. The distinction of a fluctuation from a long-term change in Earth processes is a key question to better understand processes within the Earth and in the Earth system. Likewise, it is a prerequisite for the assessment of the Earth's climate change as well as risk assessment. In order to distinguish fluctuations from a steady change, knowledge on the time variability of the signal itself and long term observations are required. Exemplarily, due to the decadal variability of sea level, reliable sea level trends can only be obtained after about sixty years of continuous observations. Reliable strain rates of deformation require a minimum of a decade of continuous data, due to ambient and anthropogenic factors leading to fluctuations. This session invites contributions demonstrating the importance of long term geophysical, geodynamic, oceanographic, geodetic, and climate observatories. Advances in sensors, instrumentation, monitoring techniques, analyses, and interpretations of data, or the comparison of approaches are welcome, with the aim to stimulate a multidisciplinary discussion among those dedicated to the accumulation, preservation and dissemination of data over decadal time scales or beyond. Studies utilizing novel approaches such as AI for analysis of long time series are very welcome. Likewise, studies that show the mutual transfer of knowledge of terrestrial and satellite observations are a topic of interest. With this session, we also would like to provide an opportunity to gather and exchange experiences for representatives from observatories both in Europe and worldwide.
The increase of climate-related hazards has been driven by climate change, increasing human activities and infrastructure development, particularly in vulnerable areas. More efforts should be directed towards effective disaster risk management to reduce damages and losses, focusing on hazard, vulnerability, and risk mapping. Remote Sensing (RS) and Geographic Information Systems (GIS) are powerful tools in mapping change and rate of change concerning natural hazards, particularly in data-scarce environments, thanks to the great advantage of sensing extended areas at low cost and with regular revisit capability. Furthermore, satellite RS offers the opportunity to gain fresh insights into biophysical environments through satellite systems' spatial, temporal, spectral, and radiometric resolutions. The advantages of RS are further supported by the analytical and geospatial data integration capabilities of GIS.
On the other hand, proximal RS offers a unique opportunity to observe processes characterized by fast dynamics and complex geometries and provides data at ultra-high temporal and spatial resolution. The number of proximal RS solutions currently adopted to study and monitor natural hazards has progressively increased in the last decades. Nowadays, UAV, terrestrial radar interferometry, and digital photogrammetry are among the most diffuse proximal systems adopted to identify precursor elements for detailed hazard assessment and support decision-makers during emergencies. In particular, the use of these systems helps create high-resolution 3D models of the study area and monitor natural hazards. The adoption of multi-scale and multi-sensor approaches can be beneficial for studying the same phenomenon from different points of view and can support a detailed description of the studied process and the most critical parameters that can be adopted for its characterization. The availability of many technical solutions represents an additional value, but the lack of defined methodologies can limit these systems' standardized use, particularly during emergencies. This session aims to explore the use of satellite and proximal RS techniques and GIS analysis in different scenarios related to natural hazards and impact analysis and mitigation, including the preliminary characterization of potential dangerous processes, the evaluation of the elements at risk, the management of the emergency phase and the support of recovery and post-emergency reconstruction.
Low-lying coastal areas can be an early casualty to sea-level rise, especially where enhanced by land subsidence. An ever increasing number of studies indicates that land subsidence due to natural and anthropogenic causes has induced damage to wetland ecosystems in many countries worldwide, and has increased flooding hazard and risk. Coastal subsidence causes include excessive groundwater extraction from aquifers, peat oxidation due to surface water drainage through land reclamation, urbanization and agricultural use, as well as sediment starvation due to construction of dams and artificial levees. Contrary to the global processes behind sea-level rise, natural and anthropogenic coastal subsidence is primarily a local phenomenon, and its causes and severity may vary substantially from place to place.
The combination of geological and historical measurements with remote sensing data is required to understand all drivers of coastal vertical land motion and the contributions to past, present, and future subsidence.
Understanding coastal subsidence requires multidisciplinary expertise, models, and remote and in-situ observations from geology, geodesy, natural hazards, oceanography, hydrogeology, and geomechanics. In this session, we aim to bring together all the involved disciplines. We invite contributions on all aspects of coastal subsidence research and applications, including recent advances on: i) measurement through ground-based, aerial and satellite remote sensing techniques, ii) numerical models and future projections, iii) their applicability to distinguish between the different drivers contributing to land subsidence, and iv) quantification of coastal hazards associated with relative sea-level rise. In particular, efforts towards characterizing human intervention on coastal vertical land motion are welcomed.

Recent developments in quantum physics has enabled novel applications and measurement concepts in geodesy and Earth‘s gravitational field observation. In this Session, we discuss new types of sensors and gravity mission concepts that require the application of the advanced techniques. We will address the measurement of the terrestrial gravity anomalies by means of observing free-falling atoms (quantum gravimetry) which is gradually replacing the falling corner cubes. Atom interferometry allows nearly continuous measurements and offers the access to gradients. It is also supposed for future gradiometric measurements in space.
According to Einstein’s theory of general relativity, frequency comparisons of highly precise optical clocks connected by optical links give a direct access to differences of the gravity potential (relativistic geodesy) which allows gravity field recovery and height determination on long baselines. In future, precise optical clocks can be applied for defining and realizing an international height system in a new way, and moreover, help to improve the accuracy of the International Atomic Time scale TAI. Optical clocks are important for all space geodetic techniques as well as for the realization of reference systems.
Additionally, laser interferometry between test masses in space with nanometer accuracy – which has been realized as a demonstrator in the GRACE-FO mission – also belongs to these novel concepts, and in the future even more refined concepts (tracking swarms of satellites, space gradiometry) will be realized.
Finally, changes in the gravity field can be derived from GNSS displacement values which play an increasingly important role due to the relatively cheap and easy deployment of GNSS receivers and the large number of stations.
All these above-mentioned techniques will open a door to a vast bundle of applications such as fast local gravimetric surveys, the gravimetric observation of the Earth-Moon system with high spatial-temporal resolution. Terrestrial mass variations can be monitored at various scales providing unique information on the climate change processes.
We invite presentations illustrating the principles and state of the art of those novel techniques and the application of the new methods for terrestrial and satellite geodesy, navigation and fundamental physics. We also welcome papers covering theoretical foundations and description of the new methods as well as revised modeling schemes.

For about two decades now, satellite missions dedicated to the determination of the Earth's gravity field have enabled a wide variety of studies related to climate research as well as other geophysical or geodetic applications. Continuing the successful, more than 15 years long data record of the Gravity Recovery and Climate Experiment (GRACE, 2002-2017) mission, its Follow-on mission GRACE-FO, launched in May 2018, is currently in orbit providing fundamental observations to monitor global gravity variations from space. Regarding the computation of high-resolution static gravity field models of the Earth and oceanic applications, the Gravity field and steady-state Ocean Circulation Explorer (GOCE, 2009-2013) mission plays an indispensable role. Complementary to these dedicated missions, observations from other non-dedicated missions such as Swarm as well as satellite laser ranging (SLR) have shown to be of significant importance, either to bridge gaps in the GRACE/GRACE-FO time series or to improve gravity field models and scientific results derived thereof. The important role of satellite gravimetry in monitoring the Earth from space has led to various ongoing initiatives preparing for future gravity missions, including simulation studies, the definition of user and mission requirements and the investigation of potential measurement equipment and orbit scenarios.
This session solicits contributions about:
(1) Results from satellite gravimetry missions as well as from non-dedicated satellite missions in terms of
- data analyses to retrieve time-variable and static global gravity field models,
- combination synergies, and
- Earth science applications.
(2) The status and study results for future gravity field missions.

Gravity and magnetic field data contribute to a wide range of geo-scientific research, from imaging the structure of the earth and geodynamic processes near surface investigations. The first part of this session is dedicated to contributions related to spatial and temporal variations of the Earth gravity and magnetic field at all scales. Contributions to modern potential field research are welcome, including instrumental issues, data processing techniques, machine learning, interpretation methods, innovative applications of the results and data collected by modern satellite missions, potential theory, as well as case histories.
The second part of this session will focus on the practical solution of various formulations of geodetic boundary-value problems to yield precise local and regional high-resolution (quasi)geoid models. Contributions describing recent developments in theory, processing methods, downward continuation of satellite and airborne data, treatment of altimetry and shipborne data, terrain modeling, software development and the combination of gravity data with other signals of the gravity field for a precise local and regional gravity field determination are welcome. Topics such as the comparison of methods and results, the interpretation of residuals as well as geoid applications to satellite altimetry, oceanography, vertical datums and local and regional geospatial height registration are of a special interest.
Terrain gravimetry is a powerful geophysical tool that, through sensing changes in subsurface mass, can supply unique information on the dynamics of underground fluids, like water, magma, hydrocarbons, etc. This is critically important for energy industry (not just petroleum and natural gas, but also geothermal), resource management (particularly, with regard to water), and natural hazards (especially volcanoes).
Despite its potential, terrain gravimetry is currently underexploited, owing to the high cost of available instrumentation and the difficulty in using it under harsh environmental conditions and to the major challenge posed by retrieving useful information from gravity changes in noisy environments.
Major technology developments have recently occurred in instrumentation and methodology and are being demonstrated, opening up new perspectives to increase the capability of terrain gravimetry. On one hand, new types of sensors are being developed and ruggedized, expanding the measurement capabilities. On the other hand, methodologies and workflows are developed to exploit more efficiently hybrid networks of sensors. As an example, a recently funded H2020 project, called NEWTON-g, targets the development and field application of a “gravity imager” exploiting MEMS (relative) and quantum (absolute) gravimeters. These advancements will give new impulse to terrain gravimetry, thus helping its transition from a niche field into a cornerstone resource for geophysical monitoring and research. However, for this transition to succeed, technology developments must be complemented by constructive feedback from the gravimetry community
This session aims at bringing together instrument and tool developers and end-users of terrain gravimetry in a variety of fields, including, but not limited to, hydrology, volcanology and petroleum geology. We aim at discussing the state of the art of terrain gravimetry and the added value it provides with respect to other geophysical techniques, as well as the exciting opportunities offered by the new technologies under development.

The term space weather indicates physical processes and phenomena in space caused by the radiation of energy mainly from the Sun. Solar and geomagnetic storms can cause disturbances in positioning, navigation and communication; coronal mass ejections (CME) can affect serious disturbances and in extreme cases damages or even destruction of modern infrastructure. The ionosphere and the thermosphere are parts of a physically coupled systems ranging from the Earth surface to the Sun including the magnetosphere and the lower atmosphere. Therefore, conducting detailed investigations on governing processes in the solar-terrestrial environment have key importance to understand the spatial and temporal variations of ionospheric and thermospheric key parameters such as the total electron content (TEC) and the plasma density of the ionosphere, as well as the thermospheric neutral density, which are influencing the orbits of Low-Earth orbiting (LEO) satellites. To address all these interrelations and impacts, the Global Geodetic Observing System (GGOS) Focus Area on Geodetic Space Weather Research was implemented into the structure of the International Association of Geodesy (IAG).
This session will address recent progress, current understanding, and future challenges of thermospheric and ionospheric research including the coupling processes. Special emphasise is laid on the modelling and forecasting of space weather time series, e.g. EUV-, X-ray radiation and CMEs, and their impact on VTEC and electron density. We encourage further contributions to the dynamo electric field, the variations of neutral and ion compositions on the bottom and top side of the ionosphere, atmospheric gravity waves and TIDs. Furthermore, we appreciate contributions on the wind dynamo, electrodynamics and disturbances, including plasma drift, equatorial spread F, plasma bubbles, and resultant scintillation.
Another main topic is global and regional high-resolution and high-precision modelling of VTEC and the electron density based on empirical, analytical or physical data assimilation approaches, which are designed for post-processing or (near) real-time purposes.

Geodesy contributes to atmospheric science by providing some of the essential climate variables of the Global Climate Observing System. Water Vapor (WV) is currently under-sampled in meteorological and climate observing systems. Obtaining more high-quality humidity observations is essential to weather forecasting and climate monitoring. The production, exploitation and evaluation of operational GNSS-Met for weather forecasting is well established in Europe due to 20+ years of cooperation between the geodetic community and the national meteorological services. Improving the skill of numerical weather prediction (NWP) models to forecast extreme precipitation requires GNSS products with a higher spatio-temporal resolution and shorter turnaround. Homogeneously reprocessed GNSS data (e.g., IGS repro3) have high potential for monitoring water vapor climatic trends and variability. With shortening orbit repeat periods, SAR measurements are a new source of information to improve NWP models. Using NWP data within real-time (RT) GNSS data analysis can initialize PPP algorithms, thus shortening convergence times and improving positioning. GNSS signals can be used for L-band remote sensing when Earth-surface reflected signals are considered. GNSS-R contributes to environmental monitoring with estimates of soil moisture, snow depth, ocean wind speed, sea ice concentration and has the potential to be used to retrieve near-surface WV.
We welcome, but not limit, contributions on:
•Estimates of the neutral atmosphere using ground- and space-based geodetic data and the use thereof in weather forecasting and climate monitoring
•Retrieval and comparison of tropospheric parameters from multi-GNSS, VLBI, DORIS and multi-sensor observations
•Now-casting, forecasting, and climate research using RT and reprocessed tropospheric products, employing numerical weather prediction and machine learning
•Assimilation of GNSS tropospheric products in NWP and in climate reanalysis
•Production of SAR tropospheric parameters and assimilation thereof in NWP
•Homogenization of long-term GNSS and VLBI tropospheric products
•Delay properties of GNSS signals for propagation experiments
•Exploitation of NWP data in GNSS data processing
•Techniques for soil moisture retrieval from GNSS data and for ground-atmosphere boundary interactions
•Detection and characterization of sea level, snow depth and sea ice changes, using GNSS-R
•Studying the atmospheric water cycle employing satellite gravimetry.

What is the “Potsdam Gravity Potato”? What is a reference frame and why is it necessary to know in which reference frame GNSS velocities are provided? Geodetic data, like GNSS data or gravity data, are used in many geoscientific disciplines, such as hydrology, glaciology, geodynamics, oceanography and seismology. This course aims to give an introduction into geodetic datasets and presents what is necessary to consider when using such data. This 105-minute short course is part of the quartet of introductory 101 courses on Geodynamics 101, Geology 101 and Seismology 101.
The short course Geodesy 101 will introduce basic geodetic concepts within the areas of GNSS and gravity data analysis. In particular, we will talk about:
- GNSS data analysis
- Reference frames
- Gravity data analysis
We will also show short examples of data handling and processing using open-source software tools. Participants are not required to bring a laptop or have any previous knowledge of geodetic data analysis.
Our aim is to give you more background information on what geodetic data can tell us and what not. You won’t be a Geodesist by the end of the short course, but we hope that you are able to have gained more knowledge about the limitations as well as advantages of geodetic data. The course is run by early career scientists from the Geodesy division, and is aimed for all attendees (ECS and non-ECS) from all divisions who are using geodetic data frequently or are just interested to know what geodesists work on on a daily basis. We hope to have a lively discussion during the short course and we are also looking forward to feedback by non-geodesists on what they need to know when they use geodetic data.

We have developed an open source software package in python for ground-based GNSS reflections – gnssrefl (https://github.com/kristinemlarson/gnssrefl). This new software supports geoscientists wishing to measure in situ snow accumulation, permafrost melt, firn density, tides, and lake/river levels. We have developed videos (hosted on youtube) to help new users understand both the basic concepts of GNSS reflections and how to install and run the gnssrefl code. More than a dozen use cases are available online; Jupyter Notebooks have been developed as well. We envision the EGU tutorial session to be hands-on and interactive, with a focus on demonstrating the gnssrefl software and online tools (https://gnss-reflections.org), examining and discussing environmental results derived from GNSS data taken from public archives, and analyzing new datasets suggested by the students.
Public information:
We have developed an open source code in python (gnssrefl) that allows users to measure either water levels or snow accumulation using GNSS data. This session will be devoted to helping users understand how to run and install the code. Please see the github (https://github.com/kristinemlarson/gnssrefl) repository for some tips on how to install the gnssrefl package on your local machine. We currently support the python code on linux and macs, with docker images for these and PCs. We also have links to jupyter notebooks. There is a complementary web app at https://gnss-reflections.org.
How do seismologists detect earthquakes? How do we locate them? Is seismology only about earthquakes? Seismology has been integrated into a wide variety of geo-disciplines to complement many fields such as tectonics, geology, geodynamics, volcanology, hydrology, glaciology and planetology. This 90-minute course is part of the Solid Earth 101 short course series together with ‘Geodynamics 101’ and ‘Geology 101’ to better illustrate the link between these fields.
In ‘Seismology 101’, we will introduce the basic concepts and methods in seismology. In previous years, this course was given as “Seismology for non-seismologists”, and it is still aimed at those not familiar with seismology -- particularly early-career scientists. An overview will be given on various methods and processing techniques applicable to investigate surface processes, near-surface geological structures, and the Earth’s interior. The course will highlight the role that advanced seismological techniques can play in the co-interpretation of results from other fields. The topics will include:
- the basics of seismology, including the detection and location of earthquakes
- understanding and interpreting those enigmatic “beachballs”
- an introduction to free seismo-live.org tutorials and other useful tools
- how seismic methods are used to learn about the Earth, such as imaging the Earth’s interior (on all scales), deciphering tectonics, monitoring volcanoes, landslides and glaciers, etc...
We likely won’t turn you in the next Charles Richter in 90 minutes but would like to make you aware of how seismology can help you with your research. The intention is to discuss each topic in a non-technical manner, emphasizing their strengths and potential shortcomings. This course will help non-seismologists better understand seismic results and facilitate more enriched discussion between different scientific disciplines. The short course is organised by early-career scientist seismologists and geoscientists who will present examples from their own research experience and high-impact reference studies for illustration. Questions from the audience on the topics covered will be highly encouraged.

The main goal of this short course is to provide an introduction into the basic concepts of numerical modelling of solid Earth processes in the Earth’s crust and mantle in a non-technical manner. We discuss the building blocks of a numerical code and how to set up a model to study geodynamic problems. Emphasis is put on best practices and their implementations including code verification, model validation, internal consistency checks, and software and data management.
The short course introduces the following topics:
(1) The physical model, including the conservation and constitutive equations
(2) The numerical model, including numerical methods, discretisation, and kinematical descriptions
(3) Code verification, including benchmarking
(4) Model design, including modelling philosophies
(5) Model validation and subsequent analysis
(6) Communication of modelling results and effective software, data, and resource management
Armed with the knowledge of a typical numerical modelling workflow, participants will be better able to critically assess geodynamic numerical modelling papers and know how to start with numerical modelling.
This short course is run by early career geodynamicists. It is aimed at everyone who is interested in, but not necessarily experienced with, geodynamic numerical models; in particular early career scientists (BSc, MSc, PhD students and postdocs) and people who are new to the field of geodynamic modelling.

This 105-minute short course aims to introduce non-geologists to structural and petrological geological principles, which are used by geologists to understand system earth.
The data available to geologists is often minimal, incomplete and representative for only part of the geological history. Besides learning field techniques to acquire and measure data, geologists need to develop a logical way of thinking to close gaps in the data to understand the system. There is a difference in the reality observed from field observation and the final geological model that tells the story.
In this course we briefly introduce the following subjects:
1) Grounding rocks: Introduction to the principles of geology.
2) Collecting rocks: The how, what, and pitfalls of field data acquisition.
3) Failing rocks: From structural field data to (paleo-)stress analysis.
4) Dating rocks: Absolute and relative dating of rocks using petrology and geochronology methods.
5) Shaping rocks: The morphology of landscapes as tectonic constraints
6) Crossing rocks over: How geology benefits from seismology, geodynamic and geodesy research, and vice-versa.
7) Q&A!
Our aim is not to make you the next specialist in geology, but we would rather try and make you aware of the challenges a geologist faces when they go out into the field. Additionally, the quality of data and the methods used nowadays are addressed to give other earth scientists a feel for the capabilities and limits of geological research. This course is given by Early Career Scientist geologists and geoscientists and forms a quartet with the short courses on ‘Geodynamics 101 (A&B)’, ‘Seismology 101’, and ‘Geodesy 101’. For this reason, we will also explain what kind of information we expect from the fields of seismology, geodynamics and geodesy, and we hope to receive some feedback in what kind of information you could use from our side.

Continental rifting is a complex process spanning from the inception of extension to continental rupture or the formation of a failed rift. This session aims at combining new data, concepts and techniques elucidating the structure and dynamics of rifts and rifted margins. We invite submissions highlighting the time-dependent evolution of processes such as: initiation and growth of faults and ductile shear zones, tectonic and sedimentary history, magma migration, storage and volcanism, lithospheric necking and rift strength loss, influence of the pre-rift lithospheric structure, rift kinematics and plate motion, mantle flow and dynamic topography, as well as break-up and the transition to sea-floor spreading. We encourage contributions using multi-disciplinary and innovative methods from field geology, geochronology, geochemistry, petrology, seismology, geodesy, marine geophysics, plate reconstruction, or numerical or analogue modelling. Special emphasis will be given to presentations that provide an integrated picture by combining results from active rifts, passive margins, failed rift arms or by bridging the temporal and spatial scales associated with rifting.

During the past 20 years, extensive research at present-day rifted margins and at fossil remnants preserved at orogenic belts has demonstrated that rifting is a complex and dynamic process. Extension can be dominated by poly-phase rifting, in which case the structure of rifted margins results from a unique kinematic event but the succession of several rift phases, resulting in a progressive migration and localisation of deformation. Multi-stage extension, however, evolves through independent rift events, which develop with distinct kinematic frameworks, leading to different but overlapping rift systems. Crustal domains and overlying rift basins are genetically linked in poly-phase rift systems, which include in-sequence syn-rift units and bounding extensional structures. In multi-stage extension, however, rift systems are out of sequence, and each of the rift systems displays a particular crustal structure and different rift basins and bounding structures. Thermal, magmatic and structural inheritance condition the onset of rifting, while inherited rift templates guide successive rift events. Complex 3D rift templates ultimately control subsequent compressional reactivation processes, leading to passive margin inversion, subduction initiation and mountain building.
This session aims to attract work that focuses on the analysis of the architecture of worldwide rift systems and related spatial and temporal evolution of rifting processes using geophysical data, fieldwork observations and associated geochemical and thermochronological studies, numerical and analogue modelling techniques, and plate kinematic reconstructions. This will enable us to compare and discuss the architecture of rift templates and their role in the evolution of extension as well as the subsequent convergence.

Geomorphic and geologic observations at the Earth's surface reflect the combined effects of mantle, lithospheric, and surface processes. Hence surface observations provide important constraints on mantle convection patterns and plume-plate interactions both at plate boundaries and in intraplate settings through space and time. These observations complement geophysical data and are important constraints for theoretical models and numerical simulations. For instance, at plate boundaries, surface observations can provide key constraints on the rheology and kinematics of lithospheric and mantle processes. In both plate boundary and intraplate settings, mantle plumes can trigger continental rifting and break-up, subduction initiation, orogeny, microcontinent formation, and/or the development of dynamic topography. However, using surface observations to constrain mantle processes is complicated by (1) our as yet incomplete understanding of how mantle dynamics manifest at the surface, and (2) spatio-temporal variations in tectonic processes, climate, isostatic adjustment, lithology, biota, and human alteration of landscapes. In this session, we aim to bring together researchers interested in mantle-surface and plume-plate interactions. We welcome studies that cover a range of techniques from data-driven approaches to numerical modelling or laboratory experiments.
We hope this session will provide opportunities for presenters from a range of disciplines, demographics, and stages of their scientific career to engage in this exciting and emerging problem in Earth Science.
The origin and evolution of the continental lithosphere is closely linked to changes in mantle dynamics through time, from its formation through melt depletion to multistage reworking and reorganisation related to interaction with melts formed both beneath and within it. Understanding this history is critical to constraining terrestrial dynamics, element cycles and metallogeny. We welcome contributions dealing with: (1) Reconstructions of the structure and composition of the lithospheric mantle, and the influence of plumes and subduction zones on root construction; (2) Interactions of plume- and subduction-derived melts and fluids with the continental lithosphere, and the nature and development of metasomatic agents; (3) Source rocks, formation conditions (P-T-fO2) and evolution of mantle melts originating below or in the mantle lithosphere; (4) Deep source regions, melting processes and phase transformation in mantle plumes and their fluids; (5) Modes of melt migration and ascent, as constrained from numerical modelling and microstructures of natural mantle samples; (6) Role of mantle melts and fluids in the generation of hybrid and acid magmas.These topics can be illuminated using the geochemistry and fabric of mantle xenoliths and orogenic peridotites, mantle-derived melts and experimental simulations.

Mantle convection is a fundamental process responsible for shaping the tectonic evolution of the Earth. Although direct observations of this process are critical, they tend to be limited in space and time; however, significant information can be obtained through a variety of multiscale methods that allow one to estimate fundamental parameters of the Earth's mantle structure (e.g., viscosity, density and temperature). Theoretically, mantle convection can be separated into the plate and plume mode. The former is associated with the cold upper thermal boundary layer (lithosphere), while the plume mode is tied to the hot lower thermal boundary layer. Convective buoyancy associated with these modes are significant, capable of driving plate motions. However, they need to be contrasted with plate boundary forces, where oblique rifting and the influence of magmatic processes highlight some of the difficulties in understanding these forces.
Seismic imaging and gravity data, for instance, provide a snapshot of processes occurring in the present-day mantle. Geochemical analysis of volcanic rocks can be used to estimate temperature and depths of melt generation through time. Numerous observations of continental breakup since the Cretaceous are well documented in the geological archives. They include mapping continental dynamic topography, studying plate kinematic changes, using thermochronological models and petrological observables, and imaging deep structure by seismic tomography to constrain the breakup history. Altogether, these classes of observations, which are commonly studied in isolation, provide powerful constraints for geodynamic forward and inverse models of past mantle convection. Hence, yielding a holistic view of the Earth's mantle and its temporal and structural evolution.

The nature of Earth’s lithospheric mantle is largely constrained from the petrological and geochemical studies of xenoliths. They are complemented by studies of orogenic peridotites and ophiolites, which show the space relationships among various mantle rock types, missing in xenoliths. Mantle xenoliths from cratonic regions are distinctly different from those occurring in younger non-cratonic areas. Percolation of melts and fluids through the lithospheric mantle significantly modifies its petrological and geochemical features, which is recorded in mantle xenoliths brought to the surface by oceanic and continental volcanism. Basalts and other mantle-derived magmas provide us another opportunity to study the chemical and physical properties the mantle. These various kinds of information, when assembled together and coupled with experiments and geophysical data, enable the understanding of upper mantle dynamics.
This session’s research focus lies on mineralogical, petrological and geochemical studies of mantle xenoliths, orogenic and ophiolitic peridotites and other mantle derived rocks. We strongly encourage the contributions on petrology and geochemistry of mantle xenoliths and other mantle rocks, experimental studies, the examples and models of mantle processes and its evolution in space and time.

Glacial Isostatic Adjustment (GIA) describes the dynamic response of the solid Earth to ice sheet glaciation/deglaciation, which affects the spatial and temporal sea level changes, and induces surface deformation, gravitational field variation and stress changes in the subsurface. The process is influenced by the ice sheet characteristics (e.g., extent, volume, grounding line) and solid Earth structure. With more observational data (e.g., relative sea-level data, GPS data, tide gauges, terrestrial and satellite gravimetry, glacially induced faults) are available/standardized, we can better investigate the interactions between the ice sheets, solid Earth and sea levels, and reveal the ice sheet and sea-level evolution histories and rheological properties of the Earth.
This session invites contributions discussing observations, analysis, and modelling of ice sheet dynamics, solid Earth response, and the resulting global, regional and local sea-level changes and land deformation, including paleo ice sheet and paleo sea-level investigations, geodetic measurements of crustal motion and gravitational change, GIA modelling with complex Earth models (e.g., 3D viscosity, non-linear rheologies) and coupled ice-sheet/Earth modelling, investigations on glacially triggered faulting as well as the Earth’s elastic response to present-day ice mass changes. We also welcome abstracts that address the future ice sheets/shelves evolution and sea-level projection as well as GIA effects on oil migration and nuclear waste repositories. Contributions related to both polar regions and previously glaciated regions are welcomed. This session is co-sponsored by the SCAR sub-committee INSTANT-EIS, Earth - Ice - Sea level, in view of instabilities and thresholds in Antarctica https://www.scar.org/science/instant/home/.
Understanding the structures and dynamics of the core of a planet is essential to construct a global geochemical and geodynamical model, it has implication on its thermal, compositional and orbital evolution.
Remote sensing of planets interior from space and ground-based observations is entering a new era with perspectives in constraining their core structures and dynamics. Meanwhile, increasingly accurate seismic and magnetic data provides unprecedented images of the Earth's deep interior. Unraveling planetary cores structures and dynamics requires a synergy between many fields of expertise, such as mineral physics, geochemistry, seismology, fluid mechanics or geomagnetism. In such a cross-disciplinary context, we identify the need to combine observations, e.g. from geo/paleo/rock magnetism, to generate field models and carefully compare their properties with numerical simulations of the dynamo process. This requires community-wide efforts to share data and models in standardized formats, which we aim to address.
This session welcomes contributions from all the disciplines mentioned following theoretical, numerical, observational or experimental approaches, with the aim to proceed towards an integrated, self-consistent picture of planetary core's structure, dynamics, magnetic field and their evolution.
Processes responsible for formation and development of the early Earth (> 2500Ma) are not well understood and strongly debated, reflecting in part the poorly preserved, altered, and incomplete nature of the geological record from this time.
In this session we encourage the presentation of new approaches and models for the development of Earth's early crust and mantle and their methods of interaction. We encourage contributions from the study of the preserved rock archive as well as geodynamic models of crustal and mantle dynamics so as to better understand the genesis and evolution of continental crust and the stabilization of cratons.
We invite abstracts from a large range of disciplines including geodynamics, geology, geochemistry, and petrology but also studies of early atmosphere, biosphere and early life relevant to this period of Earth history.

The present state of Earth and other rocky planets are an expression of dynamical and chemical processes occurring throughout their history. In particular, giant impacts, core formation and magma-ocean crystallisation and other processes occurring in the early solar system set the stage for the long-term evolution of terrestrial planets. These early processes can happen simultaneously or in recurring stages, and are ultimately followed by progressive crustal growth, long-term mantle mixing/differentiation, core-mantle interaction, as well as inner-core crystallization. The rock-record, through geochemistry and magnetism, is used to interrogate changes in the tectono-thermal regime of Earth’s interior through time, while seismic imaging and gravity data, for instance, provide a snapshot of processes occurring in the contemporary mantle, crust and core. These classes of observations may be linked through geodynamic models, whose accuracy is underpinned by the physical properties (e.g., viscosity and density) of its constituent phases (minerals, melts and fluids). Information on the fundamental thermodynamic and physical behaviour of phases is subject to constant advance via experimental and ab-initio techniques.
This session aims to provide a holistic view of the formation, dynamics, structure and composition of Earth and the evolution of terrestrial bodies by bringing together studies from geophysics, geodynamics, mineral physics, geochemistry, and petrology. This session welcomes contributions focused on data analysis, modeling and experimental work that address the formation and evolution of terrestrial planets and moons in the Solar System, and around other stars.

Processes controlling the global cycles of volatiles (e.g., C, H, O, S) across reservoirs regulate planetary climate and habitability. Their cycling pathways and efficiency are dependent on numerous factors including the presence of liquid water and the tectonic mode; and involves the atmosphere, hydrosphere, crust, mantle and even the core.
On Earth, major volatile cycles are balanced to first order through ingassing and outgassing, mainly occurring at subduction zones, and major sites of volcanism (i.e., mid-ocean ridges and hotspots), respectively. In planetary interiors, volatiles are partitioned into the existing minerals, or stabilize minor phases such as diamond or various hydrous phases in the mantle and crust, something that directly influences the spatial distribution of melt formation as well as rock properties. Conversely, melt transport induces volatile exchanges between planetary reservoirs and favours outgassing. Outgassing, in turn, will regulate planetary climates, hence influencing the habitability.
The aim of this session is to bring together numerical, experimental and observational expertise from Earth and Planetary Sciences to advance the understanding of interior-atmosphere coupling and volatile exchange and evolution on Earth and terrestrial (exo)planets, as well as the role of those volatiles on the interior composition and dynamics. This session features contributions on topics including volatile cycling, melt and volatile transport, mineral-melt phase relations, geophysical detections, tectonic regimes, outgassing, atmospheric composition and planetary habitability.
Subduction drives plate tectonics, generating the major proportion of subaerial volcanism, releasing >90% seismic moment magnitude, forming continents, and recycling lithosphere. Numerical and laboratory modeling studies have successfully built our understanding of many aspects of the geodynamics of subduction zones. Detailed geochemical studies, investigating compositional variation within and between volcanic arcs, provide further insights into systematic chemical processes at the slab surface and within the mantle wedge, providing constraints on thermal structures and material transport within subduction zones. However, with different technical and methodological approaches, model set-ups, inputs, and material properties, and in some cases conflicting conclusions between chemical and physical models, a consistent picture of the controlling parameters of subduction-zone processes has so far not emerged.
This session aims to follow subducting lithosphere on its journey from the surface down into the Earth's mantle and to understand the driving processes for deformation and magmatism in the over-riding plate. We aim to address topics such as: subduction initiation and dynamics; changes in mineral breakdown processes at the slab surface; the formation and migration of fluids and melts at the slab surface; primary melt generation in the wedge; subduction-related magmatism; controls on the position and width of the volcanic arc; subduction-induced seismicity; mantle wedge processes; the fate of subducted crust, sediments and volatiles; the importance of subducting seamounts, LIPs, and ridges; links between near-surface processes and slab dynamics and with regional tectonic evolution; slab delamination and break-off; the effect of subduction on mantle flow; and imaging subduction zone processes.
With this session, we aim to form an integrated picture of the subduction process, and invite contributions from a wide range of disciplines, such as geodynamics, modeling, geochemistry, petrology, volcanology, and seismology, to discuss subduction zone dynamics at all scales from the surface to the lower mantle, or in applications to natural laboratories.

Since approximately 90% of the seismic moment released by earthquakes worldwide occurs near subduction zones, it is crucial to improve our understanding of seismicity and the associated seismic hazard in these regions. Seismicity in subduction zones takes many forms, ranging from relatively shallow seismicity on outer-rise and splay faults and the megathrust to intermediate-depth (70-300 km) and deep events (>300 km). While most research on subduction earthquakes focuses on the megathrust, all these different seismic events contribute to the seismic hazard of a subduction zone.
This session aims to integrate our knowledge on different aspects of subduction zone seismicity to improve our understanding of the interplay between such events and their relationship to subduction dynamics. We particularly invite abstracts that use geophysical and geological observations, laboratory experiments and/or numerical models to address questions such as: (1) What are the mechanisms behind intraplate seismicity? (2) How do outer-rise and splay fault seismicity relate to the seismogenic behaviour of the megathrust? (3) How do slab dynamics influence both shallow and deep seismicity?

Subduction is one of the primary mechanisms of fluid and element cycling between
the surface and mantle in the Earth. During subduction, metamorphism in the
downgoing plate and the consequent expulsion of fluids and generation of melts
drives mineralogical, geochemical, and rheological changes affecting the mechanical
behaviour of the subducting zone system. These fluids and melts play a key role in
the long-term geochemical evolution of the Earth by preferentially fractionating
elements from the slab and introducing them to the mantle wedge, volcanic arc, and
forearc. This process is particularly relevant for volatiles, such as carbon, which can have a profound influence on the habitability of the Earth's surface. This session aims to bring together the petrology, geochemistry, geodynamics, tectonics, and geochronology community by linking subduction zone inputs, outputs and mechanisms over a range of length and timescales. We especially encourage studies that constrain the conditions, durations, and geochemical evolution of metamorphic, metasomatic, and magmatic processes leading to the transfer of material from the slab into the mantle wedge, forearc, arc, and deep mantle. We encourage participation from scientists from all backgrounds and levels of experience.

The goal of this session is to reconcile short-time/small-scale and long-time/large-scale observations, including geodynamic processes such as subduction, collision, rifting, or mantle lithosphere interactions. Despite the remarkable advances in experimental rock mechanics, the implications of rock-mechanics data for large temporal and spatial scale tectonic processes are still not straightforward, since the latter are strongly controlled by local lithological stratification of the lithosphere, its thermal structure, fluid content, tectonic heritage, metamorphic reactions, and deformation rates.
Mineral reactions have mechanical effects that may result in the development of pressure variations and thus are critical for interpreting microstructural and mineral composition observations. Such effects may fundamentally influence element transport properties and rheological behavior.
Here, we encourage presentations focused on the interplay between metamorphic processes and deformation on all scales, on the rheological behavior of crustal and mantle rocks, and time scales of metamorphic reactions in order to discuss
(1) how and when up to GPa-level differential stress and pressure variations can be built and maintained at geological timescales and modeling of such systems,
(2) deviations from lithostatic pressure during metamorphism: fact or fiction?
(3) the impact of deviations from lithostatic pressure on geodynamic reconstructions.
(4) the effect of porous fluid and partial melting on the long-term strength.
We, therefore, invite the researchers from different domains (rock mechanics, petrographic observations, geodynamic and thermo-mechanical modeling) to share their views on the way forward for improving our knowledge of the long-term rheology and chemo-thermo-mechanical behavior of the lithosphere and mantle.
Many regions of the Earth, from crust to core, exhibit anisotropic fabrics which can reveal much about geodynamic processes in the subsurface. These fabrics can exist at a variety of scales, from crystallographic orientations to regional structure alignments. In the past few decades, a tremendous body of multidisciplinary research has been dedicated to characterizing anisotropy in the solid Earth and understanding its geodynamical implications. This has included work in fields such as: (1) geophysics, to make in situ observations and construct models of anisotropic properties at a range of depths; (2) mineral physics, to explain the cause of some of these observations; and (3) numerical modelling, to relate the inferred fabrics to regional stress and flow regimes and, thus, geodynamic processes in the Earth. The study of anisotropy in the Solid Earth encompasses topics so diverse that it often appears fragmented according to regions of interest, e.g., the upper or lower crust, oceanic lithosphere, continental lithosphere, cratons, subduction zones, D'', or the inner core. The aim of this session is to bring together scientists working on different aspects of anisotropy to provide a comprehensive overview of the field. We encourage contributions from all disciplines of the earth sciences (including mineral physics, seismology, magnetotellurics, geodynamic modelling) focused on anisotropy at all scales and depths within the Earth.
Metamorphic minerals provide unique records of the tectonic processes that have shaped Earth through the ages. Innovative new approaches in metamorphic petrology, chemical and isotope micro-analysis, and geochronology provide exciting new avenues to let these minerals tell their story of deformation, reaction and fluid flow. The insights from such research provide key means of testing long-standing concepts in petrology and tectonics, and shifting paradigms in these fields.
This session will highlight integrated metamorphic petrology, with application to tectonics and development of collisional orogens, cratons and subduction zones. We welcome contributions, from petrology, (petro-)chronology, to trace-element and isotope geochemistry. Through these diverse insights, the session will provide an exciting overview of current research on metamorphic and metasomatic processes, as well as the avenues for future innovation.
The dynamics and evolution of Earth’s surface and interior are controlled by a spectrum of processes covering a wide range of length (i.e. from kilometers down to a few ångströms) and time scales (i.e. from billions of years down to picoseconds). Microstructures in planetary materials (e.g., fabrics, textures, grain sizes and distributions, shapes, cracks etc) can be used to infer, identify, and quantify metamorphic, magmatic or diagenetic processes. Coupling these microscale processes with larger scale, planetary phenomena (e.g. formation of plate boundaries or mantle convection) remains one of the key challenges in solid Earth geosciences. Fundamentally, processes such as grain size reduction, grain growth, phase changes, and the development of crystallographic preferred orientations modify the rheological properties of rocks and minerals, providing key information on the dynamics of small- to large-scale geodynamic processes. In this session, we invite contributions investigating microstructures and textures in field samples, laboratory experiments, and numerical modeling with the aim to constrain deformation processes of Earth’s surface and interior across multiple length scales.

Lithosphere evolution, reflected in the lithosphere structure, controls the deposition of mineral resources, many of which occur in specific geodynamic settings. We invite contributions from various geophysical, geodynamic, geological, and geochemical studies, as well as from numerical modeling, which address the questions how various plate tectonics and mantle dynamics processes modify the lithosphere structure, control ore deposits, and how these processes changed during the Earth's evolution. We particularly invite contributions with focus on regional geophysical studies of the crust and upper mantle.
This session is a part of the International Lithosphere Program Task Force 1. We invite contributions from everyone interested in the topic and invite them to join the ILP TF1.

Cratons form the ancient, stable cores of most of the Earth’s continents. Knowledge about the present-day architecture of cratons is the key to understand the evolution of continental plates. In addition to that, cratons concentrate many economically relevant mineral deposits, which are indispensable for a modern society. For many cratonic regions however, little is still known about the present-day lithospheric structure and how it evolved since the Archean, mainly due to their remoteness and harsh local environmental conditions. Ongoing data acquisition, as well as the usage and optimization of
remote and passive techniques have shed new light on the lithospheric architecture of cratonic regions. Recent advancements across several disciplines show that cratons are more varied and fragmented than previously assumed, which has strong implications for geodynamic interactions with the convective mantle and long-term stability.
In this session, we welcome contributions across different scales that describe the cratonic lithosphere and its evolution with time, up to the dawn of plate tectonics. We aim to address topics like: characterization and evolution of cratonic crust and lithosphere; coupling between cratonic crust and mantle; mechanisms to form, maintain and destroy cratonic roots; craton-plume interaction; the role of cratons in supercontinent configurations; connection of cratons to mineral deposits.
We would like to raise discussions within a multidisciplinary session and therefore welcome contributions across a wide range of disciplines, including, but not limited to geodynamics, geology, tectonics, seismology, gravity, geochemistry, petrology, as well as joint approaches.

The geological processes that we infer from observations of the Earth’s surface, together with the landscape features are direct consequences of the dynamic Earth, and in particular, of the interaction between tectonic plates. Seismological studies are key for unraveling the present structure and fabric of the lithosphere and the asthenosphere. However, interdisciplinary work is required to fully understand the underlying processes and how features such as anisotropies in the crust, lithospheric mantle or the asthenosphere evolved through time and how they are related. Here we want to gather those studies focusing on seismic anisotropy and deformation patterns that can successfully improve our knowledge of the processes, leading to the observed present geometries (of the crust and the upper mantle). The main goal of the session is to establish closer links between seismological observations and process-oriented modelling studies to demonstrate the potential of different methods, and to share ideas of how we can collaboratively study upper mantle structure, and how the present-day fabrics of the lithosphere relates to the contemporary deformation processes and ongoing dynamics within the asthenospheric mantle.
Contributions from studies employing seismic anisotropy observations, tomography and waveform modeling, geodetic data, numerical and analogue modelling are welcome.

Dynamic topography is an important component of topography produced by mantle flow beneath the lithosphere. Like other components topography, dynamic topography sheds control on the eustacy, coastline evolution, source-to-sink systems, and long-wavelength variations in topography within continental interior far away from plate margins. In this aspect, dynamic topography has played a vital role in exploring the relationships between plate subduction, mantle flow, and Earth surface process. The circum-Pacific domain has been undergoing multiple re-orientations in subduction and given rise to basin-mountain systems in both eastern (western North America and South America) and western (East Asia) Pacific continental margins since late Mesozoic. Prominent diversity between the modern mantle structures of East Asia and the Americas strongly indicate different plate subduction history; this difference in evolution of the plate tectonics and mantle structure is recorded in dynamic topography. Fully unraveling the four-dimensional dynamic topography and its implications for tectonics has been one of the major challenges in both East Asia and the Americas. To help understand this complex relationship, we welcome your contributions addressing topics that concentrate on (1) the formation/origin and evolution of mantle architecture, (2) spatial-temporal evolution of Earth’s surface topography, especially dynamic topography, (3) evolution of basin-mountain systems and their indication of plate subduction, and (4) 4-D geodynamic models of eastern and western Pacific continental margins and the other regions since late Mesozoic.

The North-Atlantic-Arctic realm hosts vast extended continental shelves bordering old land masses, two Large Igneous Provinces (LIPs), one of which is the largest known sub-marine LIP (Alpha-Mendeleev Ridge) and a complex ocean spreading systems, including the slowest mid-ocean spreading ridge (Gakkel Ridge) and several extinct ocean basins.
Over recent decades, increasing scientific interest has led to the acquisition of vast quantities of geological and geophysical data across the North Atlantic-Arctic realm, yet our understanding of the region has become, if anything, even more controversial than it was before. The geodynamic and geomorphological processes acting here (and globally) are key to the understanding of the structure, geodynamic and paleolandscape evolution, hazards and resources in the region.
This session provides a forum for discussions and reviews of a variety of problems linked to the North Atlanitc-Arctic geodynamics such as plate tectonic, geodynamic, compositional, thermal, structural and landscape models, configuration of sedimentary basin and to propose additional experiments that can test these models. We welcome contributions from all relevant disciplines, including, but not limited to, plate tectonics, geophysics, geodynamic modelling, igneous, metamorphic and structural geology, palaeomagnetism, sedimentology, geomorphology, geochronology, thermochronology, geochemistry and petrology.

We invite contributions that address the present and past structure and dynamics of the Alpine orogens of the Mediterranean area. Since 2015, the international AlpArray mission and related projects have generated a plethora of new data to test the hypothesis that mantle circulation driving plates’ re-organization during collision has both immediate and long-lasting effects on the structure, motion, earthquake distribution and landscape evolution in mountain belts. Links between Earth’s surface and mantle have been forged by integrating 3D geophysical imaging of the entire crust-mantle system, with geologic observations and modelling to provide a look both backwards and forwards in time, the 4th dimension. This integrated 4D approach, initially focused on the Alps, has been expanded to the Pannonian-Carpathian and Adriatic areas, and now includes the Apennines and Dinarides. A new initiative, AdriaArray, is underway to shed light on plate-scale deformation and orogenic processes in this dynamic part of the Alpine-Mediterranean chain. The forthcoming Drilling the Ivrea-Verbano zonE (DIVE) project bridges new observations across scales and investigates the evolution of the continental lower crust. This session provides an interdisciplinary platform for highlighting the newest results and open questions of the aforementioned projects, regions and themes.

The Mediterranean region holds a plate boundary zone undergoing final closure between two major plates, Africa and Eurasia. The active tectonics and geodynamics of the Mediterranean region result from the interaction of subduction and collision processes, deformation of the slabs, mantle flow, and extrusion of crustal blocks. These geodynamic processes have a transient nature and their changes affect the regional tectonics.
This session focuses on two aspects of the Mediterranean recent active tectonics and geodynamics:
(1) how (active) geodynamic mechanisms define the current structure and recent evolution of Mediterranean Arc systems.
(2) how the surface deformation is accommodated, both on fault local scale (e.g. the seismic cycle and kinematics of active faults) and in the larger (e.g. regional kinematics and relation the surface deformation to the deeper processes).
We welcome contributions from a wide range of disciplines including, but not limited to seismology, tectonic geodesy, remote sensing, paleoseismology, tectonic geomorphology, active tectonics, structural geology, and geodynamic modeling.
We strongly encourage the contribution of early career researchers.
This session is formed by merging of TS sessions: "Active tectonics and geodynamics of the Eastern Mediterranean" & "Recent geodynamic evolution and active tectonics of Mediterranean Arcs"

The Tethyan orogenic belt is one of the largest and most prominent collisional zones on Earth. The belt ranges from the Mediterranean in the west to Papua New Guinea in the east. It results from the subduction and closure of multiple basins of the Tethys Ocean and the subsequent collision of the African, Arabian and Indian continental plates with Eurasia. Its long-lasting geological record of the opening and closure of oceanic basins, the accretion of arcs and microcontinents, the complex interactions of major and smaller plates, and the presence of subduction zones at different evolutionary stages, has progressively grown as a comprehensive test site to investigate fundamental plate tectonics and geodynamic processes with multiple disciplines. Advances in a variety of fields provide a rich and growing set of constraints on the crust-lithosphere and mantle structure and their physical and chemical characteristics, as well as the tectonics and geodynamic evolution of the Tethyan orogenic belt.
We welcome contributions presenting new insights and observations derived from different perspectives, including geology (tectonics, stratigraphy, petrology, geochronology, geochemistry, and geomorphology), geophysics (seismicity, seismic imaging, seismic anisotropy, gravity), geodesy (GPS, InSAR), modelling (numerical and analogue), natural hazards (earthquakes, volcanism). In particular, we encourage the submission of trans-disciplinary studies, which integrate observations across a range of spatial and temporal scales to further our understanding of plate tectonics as a planetary process of fundamental importance.
The Arabian Plate recorded several plate reorganizations from the Neoproterozoic to present, including the Cadomian and Angudan orogenies, Late Paleozoic rifting and Alpine Orogeny. Active tectonics are framing the Arabian Plate and produce a variety of structures, including extensional structures related to rifting of the Red Sea and Gulf and Aden, strike-slip structures at the Dead Sea and Owen transform faults and compressive structures related to the Zagros-Makran convergence zone. The Arabian Peninsula contains the planet’s largest hydrocarbon reservoirs, owing to its geological history as Gondwana’s passive margin during the Permo-Mesozoic. Moreover, the Semail Ophiolite as the largest exposed ophiolite on Earth offers a unique example of large-scale obduction and overridden sedimentary basins. This and the spectacular outcrop conditions make the Arabian Peninsula an important and versatile study area. Ongoing research and new methods shed new light on, e.g., mountain building processes and its geomorphological expression as well as hydrocarbon development/migration.
We invite contributions that utilize structural, geophysical, tectonic, geochronological, geomorphological, sedimentary, geochemical/mineralogical, and field geological studies from the Arabian Peninsula and surrounding mountain belts and basins. These studies may include topics dealing with structures/basin analyses of any scale and from all tectonic settings ranging from the Neoproterozoic until today.
Geological and geophysical data sets are in essence the result of physical processes governing the Earth’s evolution. Such data sets are widely varied and range from the internal structure of the Earth, plate kinematics, composition of geomaterials, estimation of physical conditions, dating of key geological events, thermal state of the Earth to more shallow processes such as natural and “engineered” reservoir dynamics and waste sequestration in the subsurface.
Combining such data with process-based numerical models is required for our understanding of the dynamical Earth. Process-based models are powerful tools to predict the evolution of complex natural systems resolving the feedback among various physical processes. Integrating high-quality data into numerical simulations leads to a constructive workflow to further constrain the key parameters within the models. Innovative inversion strategies, linking forward dynamic models with observables, is therefore an important research topic that will improve our knowledge of the governing physical parameters.
The complexity of geological systems arises from their multi-physics nature, as they combine hydrological, thermal, chemical and mechanical processes (e.g. thermo-mechanical convection). Multi-physics couplings are prone to nonlinear interactions ultimately leading to spontaneous localisation of flow and deformation. Understanding the couplings among those processes therefore requires the development of appropriate tools to capture spontaneous localisation and represents a challenging though essential research direction.
We invite contributions from the following two complementary themes:
1. Computational advances associated with
- alternative spatial and/or temporal discretisation for existing forward/inverse models
- scalable HPC implementations of new and existing methodologies (GPUs / multi-core)
- solver and preconditioner developments
- AI / Machine learning-based approaches
- code and methodology comparisons (“benchmarks”)
- open source implementations for the community
2. Physics advances associated with
- development of partial differential equations to describe geological processes
- inversion strategies and adjoint-based modelling
- numerical model validation through comparison with observables (data)
- scientific discovery enabled by 2D and 3D modelling
- utilisation of coupled models to explore nonlinear interactions

Long term observations are of vital importance in the Earth Sciences, yet often difficult to pursue and fund. The distinction of a fluctuation from a long-term change in Earth processes is a key question to better understand processes within the Earth and in the Earth system. Likewise, it is a prerequisite for the assessment of the Earth's climate change as well as risk assessment. In order to distinguish fluctuations from a steady change, knowledge on the time variability of the signal itself and long term observations are required. Exemplarily, due to the decadal variability of sea level, reliable sea level trends can only be obtained after about sixty years of continuous observations. Reliable strain rates of deformation require a minimum of a decade of continuous data, due to ambient and anthropogenic factors leading to fluctuations. This session invites contributions demonstrating the importance of long term geophysical, geodynamic, oceanographic, geodetic, and climate observatories. Advances in sensors, instrumentation, monitoring techniques, analyses, and interpretations of data, or the comparison of approaches are welcome, with the aim to stimulate a multidisciplinary discussion among those dedicated to the accumulation, preservation and dissemination of data over decadal time scales or beyond. Studies utilizing novel approaches such as AI for analysis of long time series are very welcome. Likewise, studies that show the mutual transfer of knowledge of terrestrial and satellite observations are a topic of interest. With this session, we also would like to provide an opportunity to gather and exchange experiences for representatives from observatories both in Europe and worldwide.
Geologic processes are generally too slow, too rare, or too deep to be observed in-situ and to be monitored with a resolution high enough to understand their dynamics. Analogue experiments and numerical simulation have thus become an integral part of the Earth explorer's toolbox to select, formulate, and test hypotheses on the origin and evolution of geological phenomena.
To foster synergy between the rather independently evolving experimentalists and modellers we provide a multi-disciplinary platform to discuss research on tectonics, structural geology, rock mechanics, geodynamics, volcanology, geomorphology, and sedimentology.
We therefore invite contributions demonstrating the state-of-the-art in analogue and numerical / analytical modelling on a variety of spatial and temporal scales, varying from earthquakes, landslides and volcanic eruptions to sedimentary processes, plate tectonics and landscape evolution. We especially welcome those presentations that discuss model strengths and weaknesses, challenge the existing limits, or compare/combine the different modelling techniques to realistically simulate and better understand the Earth's behaviour.

Environmental systems often span spatial and temporal scales covering different orders of magnitude. The session is oriented toward collecting studies relevant to understand multiscale aspects of these systems and in proposing adequate multi-platform and inter-disciplinary surveillance networks monitoring tools systems. It is especially aimed to emphasize the interaction between environmental processes occurring at different scales. In particular, special attention is devoted to the studies focused on the development of new techniques and integrated instrumentation for multiscale monitoring of high natural risk areas, such as volcanic, seismic, energy exploitation, slope instability, floods, coastal instability, climate changes, and another environmental context.
We expect contributions derived from several disciplines, such as applied geophysics, geology, seismology, geodesy, geochemistry, remote and proximal sensing, volcanology, geotechnical, soil science, marine geology, oceanography, climatology, and meteorology. In this context, the contributions in analytical and numerical modeling of geological and environmental processes are also expected.
Finally, we stress that the inter-disciplinary studies that highlight the multiscale properties of natural processes analyzed and monitored by using several methodologies are welcome.

Gravity and magnetic field data contribute to a wide range of geo-scientific research, from imaging the structure of the earth and geodynamic processes near surface investigations. The first part of this session is dedicated to contributions related to spatial and temporal variations of the Earth gravity and magnetic field at all scales. Contributions to modern potential field research are welcome, including instrumental issues, data processing techniques, machine learning, interpretation methods, innovative applications of the results and data collected by modern satellite missions, potential theory, as well as case histories.
The second part of this session will focus on the practical solution of various formulations of geodetic boundary-value problems to yield precise local and regional high-resolution (quasi)geoid models. Contributions describing recent developments in theory, processing methods, downward continuation of satellite and airborne data, treatment of altimetry and shipborne data, terrain modeling, software development and the combination of gravity data with other signals of the gravity field for a precise local and regional gravity field determination are welcome. Topics such as the comparison of methods and results, the interpretation of residuals as well as geoid applications to satellite altimetry, oceanography, vertical datums and local and regional geospatial height registration are of a special interest.
This session will cover applied and theoretical aspects of
geophysical imaging, modelling and inversion using active- and
passive-source seismic measurements as well as other geophysical
techniques (e.g., gravity, magnetic and electromagnetic) to
investigate properties of the Earth’s lithosphere and asthenosphere,
and explore the processes involved. We invite contributions focused on
methodological developments, theoretical aspects, and applications.
Studies across the scales and disciplines are particularly welcome.
Among others, the session may cover the following topics:
- Active- and passive-source imaging using body- and surface-waves;
- Full waveform inversion developments and applications;
- Advancements and case studies in 2D and 3D imaging;
- Interferometry and Marchenko imaging;

The main goal of this short course is to provide an introduction into the basic concepts of numerical modelling of solid Earth processes in the Earth’s crust and mantle in a non-technical manner. We discuss the building blocks of a numerical code and how to set up a model to study geodynamic problems. Emphasis is put on best practices and their implementations including code verification, model validation, internal consistency checks, and software and data management.
The short course introduces the following topics:
(1) The physical model, including the conservation and constitutive equations
(2) The numerical model, including numerical methods, discretisation, and kinematical descriptions
(3) Code verification, including benchmarking
(4) Model design, including modelling philosophies
(5) Model validation and subsequent analysis
(6) Communication of modelling results and effective software, data, and resource management
Armed with the knowledge of a typical numerical modelling workflow, participants will be better able to critically assess geodynamic numerical modelling papers and know how to start with numerical modelling.
This short course is run by early career geodynamicists. It is aimed at everyone who is interested in, but not necessarily experienced with, geodynamic numerical models; in particular early career scientists (BSc, MSc, PhD students and postdocs) and people who are new to the field of geodynamic modelling.

Publishing your research in a peer reviewed journal is essential for a career in research. All EGU-affiliated journals are fully open access which is great, but the unique open discussion and transparent peer review process can be daunting for first time submitters and early career scientists. This short course will cover all you need to know about the publication process from start to end for EGU journals, and give you a chance to ask the editors some questions. This includes: what the editor looks for in your submitted paper, how to deal with corrections or rejections, and how best to communicate with your reviewers and editors for a smooth transition from submission to publication. Ample time will be reserved for open discussion for the audience to ask questions to the editors, and for the editors to suggest ‘top tips’ for successful publication. This course is aimed at early-career researchers who are about to step into the publication process, and those who are yet to publish in EGU journals. Similarly, this course will be of interest to those looking to get involved in the peer-review process through reviewing and editing. This short course is part of the “Meet the EGU Journal Editors” webinar series that was held prior to the EGU General Assembly 2022.

We are excited to welcome our panelists for this session, who will be representing their respective journals:
This 105-minute short course aims to introduce non-geologists to structural and petrological geological principles, which are used by geologists to understand system earth.
The data available to geologists is often minimal, incomplete and representative for only part of the geological history. Besides learning field techniques to acquire and measure data, geologists need to develop a logical way of thinking to close gaps in the data to understand the system. There is a difference in the reality observed from field observation and the final geological model that tells the story.
In this course we briefly introduce the following subjects:
1) Grounding rocks: Introduction to the principles of geology.
2) Collecting rocks: The how, what, and pitfalls of field data acquisition.
3) Failing rocks: From structural field data to (paleo-)stress analysis.
4) Dating rocks: Absolute and relative dating of rocks using petrology and geochronology methods.
5) Shaping rocks: The morphology of landscapes as tectonic constraints
6) Crossing rocks over: How geology benefits from seismology, geodynamic and geodesy research, and vice-versa.
7) Q&A!
Our aim is not to make you the next specialist in geology, but we would rather try and make you aware of the challenges a geologist faces when they go out into the field. Additionally, the quality of data and the methods used nowadays are addressed to give other earth scientists a feel for the capabilities and limits of geological research. This course is given by Early Career Scientist geologists and geoscientists and forms a quartet with the short courses on ‘Geodynamics 101 (A&B)’, ‘Seismology 101’, and ‘Geodesy 101’. For this reason, we will also explain what kind of information we expect from the fields of seismology, geodynamics and geodesy, and we hope to receive some feedback in what kind of information you could use from our side.

What is the “Potsdam Gravity Potato”? What is a reference frame and why is it necessary to know in which reference frame GNSS velocities are provided? Geodetic data, like GNSS data or gravity data, are used in many geoscientific disciplines, such as hydrology, glaciology, geodynamics, oceanography and seismology. This course aims to give an introduction into geodetic datasets and presents what is necessary to consider when using such data. This 105-minute short course is part of the quartet of introductory 101 courses on Geodynamics 101, Geology 101 and Seismology 101.
The short course Geodesy 101 will introduce basic geodetic concepts within the areas of GNSS and gravity data analysis. In particular, we will talk about:
- GNSS data analysis
- Reference frames
- Gravity data analysis
We will also show short examples of data handling and processing using open-source software tools. Participants are not required to bring a laptop or have any previous knowledge of geodetic data analysis.
Our aim is to give you more background information on what geodetic data can tell us and what not. You won’t be a Geodesist by the end of the short course, but we hope that you are able to have gained more knowledge about the limitations as well as advantages of geodetic data. The course is run by early career scientists from the Geodesy division, and is aimed for all attendees (ECS and non-ECS) from all divisions who are using geodetic data frequently or are just interested to know what geodesists work on on a daily basis. We hope to have a lively discussion during the short course and we are also looking forward to feedback by non-geodesists on what they need to know when they use geodetic data.

How do seismologists detect earthquakes? How do we locate them? Is seismology only about earthquakes? Seismology has been integrated into a wide variety of geo-disciplines to complement many fields such as tectonics, geology, geodynamics, volcanology, hydrology, glaciology and planetology. This 90-minute course is part of the Solid Earth 101 short course series together with ‘Geodynamics 101’ and ‘Geology 101’ to better illustrate the link between these fields.
In ‘Seismology 101’, we will introduce the basic concepts and methods in seismology. In previous years, this course was given as “Seismology for non-seismologists”, and it is still aimed at those not familiar with seismology -- particularly early-career scientists. An overview will be given on various methods and processing techniques applicable to investigate surface processes, near-surface geological structures, and the Earth’s interior. The course will highlight the role that advanced seismological techniques can play in the co-interpretation of results from other fields. The topics will include:
- the basics of seismology, including the detection and location of earthquakes
- understanding and interpreting those enigmatic “beachballs”
- an introduction to free seismo-live.org tutorials and other useful tools
- how seismic methods are used to learn about the Earth, such as imaging the Earth’s interior (on all scales), deciphering tectonics, monitoring volcanoes, landslides and glaciers, etc...
We likely won’t turn you in the next Charles Richter in 90 minutes but would like to make you aware of how seismology can help you with your research. The intention is to discuss each topic in a non-technical manner, emphasizing their strengths and potential shortcomings. This course will help non-seismologists better understand seismic results and facilitate more enriched discussion between different scientific disciplines. The short course is organised by early-career scientist seismologists and geoscientists who will present examples from their own research experience and high-impact reference studies for illustration. Questions from the audience on the topics covered will be highly encouraged.

Autonomous and unmanned systems are changing the way that we collect and process geoscience data. Their capabilities and potential applications will only continue to grow. Automated systems are now used for routine data collection in high risk environments, emergency response activities, and precision agriculture for species composition monitoring and evaluating vegetation health. The aim of this session is to bring together geoscience researchers to present on the newest systems, payloads, and research goals. We invite contributions from those integrating these autonomous systems into their scientific research, system and sensor development teams, as well as those operators working on the integration of unmanned aircraft systems into manned airspace. The session brings together experts in all aspects of autonomous and unmanned system mission planning, regulations, operations, data collection, processing, and analysis to foster interdisciplinary research and knowledge-transfer across the sciences.

This interdisciplinary session brings together modellers and observationalists to present results and exchange knowledge and experience in the use of inverse methods, geostatistics and data assimilation - including machine learning - in cryospheric science.
In numerous research fields it is now possible not only to deduce static features of a physical system but also to retrieve information on transient processes between different states or even regime shifts. In the cryospheric sciences a large potential for future developments lies at the intersection of observations and models with the aim to yield prognostic capabilities in space and time. Compared to other geoscientific disciplines like meteorology or oceanography, where techniques such as data assimilation have been well established for decades, in cryospheric sciences only the foundation has been laid for the use of these techniques, one reason often being the sparsity of observations.
We invite contributions from a wide range of methodologies - from satellite observations to deep-looking geophysical methods and advancements in numerical techniques, and from topics including permafrost, sea ice and snow to glaciers and ice sheets, covering static system characterisations as well as transient processes.

Increasing effects of climate change, urbanization, and increased interconnectedness between ecological, physical, human, and technological systems pose major challenges to disaster risk management in a globalised world. Economic losses from natural hazards and climate change are still increasing, and the recent series of catastrophic events across the world together with the COVID-19 crisis has manifested the urgent need to shift from single-hazard-based approaches to new and innovative ways of assessing and managing risk based on a multi-hazard and systemic risk lens. This calls for novel scientific approaches and new types of data collections to integrate the study of multiple natural processes and human influences triggering hazards, including studies of ecological, physical, socioeconomic, political, and technical factors that shape exposure and vulnerability of humans, sectors and systems across borders and scales.
Tackling the above challenges, this session aims to gather the latest research, empirical studies, and observation data that are useful for understanding and assessing the interplay between multiple natural hazards and social vulnerability to: (i) identify persistent gaps, (ii) propose potential ways forward, and (iii) inform resilience building strategies in the context of global change.

The soil is a key system of the biosphere that supports the existence and development of human civilization. However, the growing anthropic activities are accompanied by an expansion of soil pollution. From a geochemical point of view, anthropic activities lead to the emergence of a new state of the biosphere - the noosphere, when anthropogenic chemical elements and their compounds are added to natural soil. This determines the current spatial heterogeneity of the chemical composition of the soil and vegetation cover. Such an alteration to soil composition/properties can cause negative biological impacts on both native and introduced species in local biocenosis, as well as the emergence of endemic diseases among plants animals, and humans. Human diseases can be aggravated by the fact that Homo sapiens evolving as a species under certain environmental/geochemical conditions inherited a corresponding need for certain dietary elements to maintain homeostatic regulation. As a result, people, like other organisms, need to ingest elements in the correct amounts, otherwise, they suffer from a deficiency or excess of these elements. A negative reaction may occur when the species’ natural metabolism fails to compensate for this imbalance in the life cycle. Therefore, complex studies on the identification, spatial distribution, migration, and concentration of the contaminants in soils, plants, and surface and groundwater in urban, mining, agricultural/forest, and natural areas, as well as its biological effects, is an essential issue and important task for 1)identification of zones of different natural and man-made ecological risks; 2)understanding contaminants’ pathways and impact, and 3)mitigation or elimination of negative biological effects, including the spread of non-communicable endemic diseases.
At this session, participants are invited to present their new data on soil pollution, as well as to show ideas and approaches to the solution of the problem of soil reclamation, to show results that contribute to modern knowledge on the ecological and geochemical assessment of various regions of the world exposed to anthropic geochemical impact, including industrial pollution, transport, mining and use of fertilizers and biocides. We also welcome presentations devoted to methodological problems on soil pollution assessment, the creation of ecological and geochemical databases, and compiling risk maps. We hope that live discussion will contribute to each study.

The virus is still with us, with more potent variants. It remains the most immediate challenge for geosciences and health, including its impacts on geoscience development (data collection, training, dissemination) and the achievement of the UN Sustainable Development Goals, in particular that urban systems should increase well-being and health.
Long-term visions based on transdisciplinary scientific advances are therefore essential. As a consequence, this session, like the ITS1.1 session in 2021, calls for contributions based on data-driven and theory-based approaches to health in the context of global change. This includes :
- main lessons from lockdowns?
- how to get the best scientific results during a corona pandemic?
- how to manage field works, geophysical monitoring and planetary missions?
- qualitative improvements in epidemic modelling, with nonlinear, stochastic, and complex system science approaches;
- eventual interactions between weather and/or climate factors and epidemic/health problems
- new surveillance capabilities (including contact tracing), data access, assimilation and multidimensional analysis techniques;
- a fundamental revision of our urban systems, their greening and their need for mobility;
- a special focus on urban biodiversity, especially to better manage virus vectors;
- urban resilience must include resilience to epidemics, and therefore requires revisions of urban governance.

Geomorphometry and landform mapping are important tools used for understanding landscape processes and dynamics on Earth and other planetary bodies. The recent rapid advances in technology and data collection methods have made available vast quantities of geospatial data offering unprecedented spatio-temporal range, density, and resolution, but it also created new challenges in terms of data processing and analysis.
This inter-disciplinary session on geomorphometry and landform mapping aims to bridge the gap between process-focused research fields and the technical domain where geospatial products and analytical methods are developed. The increasing availability of a wide range of geospatial datasets requires the continued development of new tools and analytical approaches as well as landform/landscape classifications. However, a potential lack of communication across disciplines results in efforts to be mainly focused on problems within individual fields. We aim to foster collaboration and the sharing of ideas across subject-boundaries, between technique developers and users, enabling us as a community to fully exploit the wealth of geospatial data that is now available.
We welcome perspectives on geomorphometry and landform mapping from ANY discipline (e.g. geomorphology, planetary science, natural hazard assessment, computer science, remote sensing). This session aims to showcase both technical and applied studies, and we welcome contributions that present (a) new techniques for collecting or deriving geospatial data products, (b) novel tools for analysing geospatial data and extracting innovative geomorphometric variables, (c) mapping and/or morphometric analysis of specific landforms as well as whole landscapes, and (d) mapping and/or morphometric analysis of newly available geospatial datasets. Contributions that demonstrate multi-method or inter-disciplinary approaches are particularly encouraged. We also actively encourage contributors to present tools/methods that are “in development”.

Non-destructive testing (NDT) methods are employed in a variety of engineering and geosciences applications and their stand-alone use has been greatly investigated to date. New theoretical developments, technological advances and the progress achieved in surveying, data processing and interpretation have in fact led to a tremendous growth of the equipment reliability, allowing outstanding data quality and accuracy.
Nevertheless, the requirements of comprehensive site and material investigations may be complex and time-consuming, involving multiple expertise and multiple equipment. The challenge is to step forward and provide an effective integration between data outputs with different physical quantities, scale domains and resolutions. In this regard, enormous development opportunities relating to data fusion, integration and correlation between different NDT methods and theories are to be further investigated.
This Session primarily aims at disseminating contributions from state-of-the-art NDT methods and new numerical developments, promoting the integration of existing equipment and the development of new algorithms, surveying techniques, methods and prototypes for effective monitoring and diagnostics. NDT techniques of interest are related–but not limited to–the application of acoustic emission (AE) testing, electromagnetic testing (ET), ground penetrating radar (GPR), geoelectric methods (GM), laser testing methods (LM), magnetic flux leakage (MFL), microwave testing, magnetic particle testing (MT), neutron radiographic testing (NR), radiographic testing (RT), thermal/infrared testing (IRT), ultrasonic testing (UT), seismic methods (SM), vibration analysis (VA), visual and optical testing (VT/OT).
The Session will focus on the application of different NDT methods and theories and will be related –but not limited to– the following investigation areas:
- advanced data fusion;
- advanced interpretation methods;
- design and development of new surveying equipment and prototypes;
- real-time and remote assessment and monitoring methods for material and site inspection (real-life and virtual reality);
- comprehensive and inclusive information data systems for the investigation of survey sites and materials;
- numerical simulation and modelling of data outputs with different physical quantities, scale domains and resolutions;
- advances in NDT methods, numerical developments and applications (stand-alone use of existing and state-of-the-art NDTs).
The session gathers geoscientific aspects such as dynamics, reactions, and environmental/health consequences of radioactive materials that are massively released accidentally (e.g., Chernobyl and Fukushima nuclear power plant accidents, wide fires, etc.) and by other human activities (e.g., nuclear tests).
The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Thus, the radioactive contamination problem is multi-disciplinary. In fact, this topic involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic and ecosystem, and its relations with human and non-human biota. The topic also involves hazard prediction and nowcast technology.
By combining 35 years (> halftime of Cesium 137) monitoring data after the Chernobyl Accident in 1986, 10 years dense measurement data by the most advanced instrumentation after the Fukushima Accident in 2011, and other events, we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents.
The following specific topics have traditionally been discussed:
(a) Atmospheric Science (emissions, transport, deposition, pollution);
(b) Hydrology (transport in surface and ground water system, soil-water interactions);
(c) Oceanology (transport, bio-system interaction);
(d) Soil System (transport, chemical interaction, transfer to organic system);
(e) Forestry;
(f) Natural Hazards (warning systems, health risk assessments, geophysical variability);
(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).
The session consists of updated observations, new theoretical developments including simulations, and improved methods or tools which could improve observation and prediction capabilities during eventual future nuclear emergencies. New evaluations of existing tools, past nuclear contamination events and other data sets also welcome.

Machine learning, artificial intelligence and big data approaches have recently emerged as key tools in understanding the cryosphere. These approaches are being increasingly applied to answer long standing questions in cryospheric science, including those relating to remote sensing, forecasting, and improving process understanding across Antarctic, Arctic and Alpine regions. In doing so, data science and AI techniques are being used to gain insight into system complexity, analyse data on unprecedented temporal and spatial scales, and explore much wider parameter spaces than were previously possible.
In this session we invite submissions that utilise data science and/or AI techniques that address research questions relating to glaciology, sea ice, permafrost and/or polar climate science. Approaches used may include (but are not limited to) machine learning, artificial intelligence, big data processing/automation techniques, advanced statistics, and innovative software/computing solutions. These could be applied to any (or combinations) of data sources including remote sensing, numerical model output and field/lab observations. We particularly invite contributions that apply techniques and approaches that reveal new insights into cryospheric research problems that would not otherwise be achievable using traditional methods, and those that discuss how or if approaches can be applied or adapted to other areas of cryospheric science. Given the rapid development of this field by a diverse group of international researchers, we convene this session to help foster future collaboration amongst session contributors, attendees, and international stakeholders and help address the most challenging questions in cryospheric science.

Long term observations are of vital importance in the Earth Sciences, yet often difficult to pursue and fund. The distinction of a fluctuation from a long-term change in Earth processes is a key question to better understand processes within the Earth and in the Earth system. Likewise, it is a prerequisite for the assessment of the Earth's climate change as well as risk assessment. In order to distinguish fluctuations from a steady change, knowledge on the time variability of the signal itself and long term observations are required. Exemplarily, due to the decadal variability of sea level, reliable sea level trends can only be obtained after about sixty years of continuous observations. Reliable strain rates of deformation require a minimum of a decade of continuous data, due to ambient and anthropogenic factors leading to fluctuations. This session invites contributions demonstrating the importance of long term geophysical, geodynamic, oceanographic, geodetic, and climate observatories. Advances in sensors, instrumentation, monitoring techniques, analyses, and interpretations of data, or the comparison of approaches are welcome, with the aim to stimulate a multidisciplinary discussion among those dedicated to the accumulation, preservation and dissemination of data over decadal time scales or beyond. Studies utilizing novel approaches such as AI for analysis of long time series are very welcome. Likewise, studies that show the mutual transfer of knowledge of terrestrial and satellite observations are a topic of interest. With this session, we also would like to provide an opportunity to gather and exchange experiences for representatives from observatories both in Europe and worldwide.
Soil pollution is a worldwide problem, which can result in a negative impact in (terrestrial) ecosystems, surface and groundwater, and the food chain. According to the European Commission, there are around 2.8 million soil pollution events contributing to soil pollution. Of these, 25 % have been identified and registered, but only 5% need mitigation strategies. In order to address soil pollution and develop preventive and mitigation strategies, it is necessary to invest in (i) the identification and characterization of these sites, from contaminant identification to ecosystem characterisation, and (ii) the identification of potential solutions. This requires linking new strategies (e.g. machine learning, artificial intelligence, digital data mapping) with natural solutions (e.g. soil-microorganisms-root-plant interaction). We welcome our colleagues to present their latest and ongoing findings and look forward to establishing new partnerships to create holist strategies that can help to prevent, assess and mitigate soil pollution consistently and swiftly.
Since its inception, data assimilation has proven to be enormously useful in the most varied fields throughout the Earth Sciences. It is certainly essential in meteorology, where the short-range forecasts would otherwise be almost impossible. In oceanography, its development has been slower, partly due to the smaller number of continuous and stable observations, and partly due to the fewer studies that show the importance of ocean forecasts for societal benefit. However, recently, these techniques are used more and more widely, both in operational oceanography and to produce climate reconstructions. Although the techniques are similar to those used in the atmospheric field, they have to deal with particularities due to the different environment, where the boundary conditions, open and closed, have greater importance, and the sparsity of observations poses unique challenges.
In this session, we welcome contributions describing data assimilation techniques, both methodological and case studies, in the oceanographic field. We welcome presentations of new techniques or new types of observations that cover every aspect of data assimilation, including varied applications of data assimilation, both in coastal seas and the open ocean.

Big data analytics will have a primary role in addressing modern challenges such as climate change, disaster management, public health and safety, resources management, and logistics. Most of these phenomena are characterized by spatio-temporal patterns that have been traditionally investigated using linear statistical approaches, as in the case of physically-based models and geostatistical models. Additionally, the rising attention toward machine learning, the variety of modern technologies generating massive volumes of geospatial data at local and global scales, and the rapid growth of computational resources, open new horizons in understanding, modelling, and forecasting complex spatio-temporal systems using stochastics non-linear models.
This session aims at exploring the new challenges and opportunities opened by the spread of big geospatial datasets and data-driven statistical learning approaches in Earth and Soil Sciences. We invite cutting-edge contributions related to methods of spatio-temporal geostatistics or data mining on topics that include, but are not limited to:
- advances in spatio-temporal modeling using geostatistics and machine learning;
- software and infrastructure development for geospatial data;
- uncertainty quantification and representation;
- innovative techniques of knowledge extraction based on clustering, pattern recognition and, more generally, data mining.
The main applications will be closely related to the research in environmental sciences and quantitative geography. A non-complete list of possible applications includes:
- natural and anthropogenic hazards (e.g. floods; landslides; earthquakes; wildfires; soil, water, and air pollution);
- interaction between geosphere and anthroposphere (e.g. land degradation; urban sprawl);
- socio-economic sciences, characterized by the spatial and temporal dimension of the data (e.g. public health management, census data; transport; commuter traffic).
This session collects the abstract submitted to the session “Strategies and Applications of AI and ML in a Spatiotemporal Context” and “Spatio-temporal Data Science: Theoretical Advances and Applications in Computational Geosciences”.

Globally, geoscience and research analytical laboratories collect ever increasing volumes of data: an acute challenge now is how to collate, store and make these data accessible in a standardised, interoperable and machine-accessible form that is FAIR. Many solutions today are bespoke and inefficient, lacking, for example, unique identification of samples, instruments, and data sets needed to trace the analytical history of the data; and there are few community agreed standards to facilitate sharing and interoperability between systems.
The push for a solution is being driven by publishers and journals who increasingly require researchers to provide access to the supporting data from a trusted repository prior to publication of manuscripts or finalisation of grants. We urgently need community development of systems to facilitate easy and efficient management of geoanalytical laboratory data. We need to address the lack of global standards, best practices and protocols for analytical data management and exchange, in order for scientists to better share their data in a global network of distributed databases. Buy-in from users and laboratory managers/technicians is essential in order to develop efficient and supported mechanisms.
This session seeks a diversity of papers from any initiative around the world that organises and structures sample/field metadata and research laboratory data at any scale to facilitate sharing and processing of geoanalytical data. We welcome papers on data and metadata standardisation efforts and papers on data management and systems that transfer data/metadata from instruments to shared data systems and relevant persistent repositories. Efforts on how to collate, curate, share and publicise sample/data collections as well as papers on the social dynamics of building sharing systems/frameworks are also welcome.

We have developed an open source software package in python for ground-based GNSS reflections – gnssrefl (https://github.com/kristinemlarson/gnssrefl). This new software supports geoscientists wishing to measure in situ snow accumulation, permafrost melt, firn density, tides, and lake/river levels. We have developed videos (hosted on youtube) to help new users understand both the basic concepts of GNSS reflections and how to install and run the gnssrefl code. More than a dozen use cases are available online; Jupyter Notebooks have been developed as well. We envision the EGU tutorial session to be hands-on and interactive, with a focus on demonstrating the gnssrefl software and online tools (https://gnss-reflections.org), examining and discussing environmental results derived from GNSS data taken from public archives, and analyzing new datasets suggested by the students.
Public information:
We have developed an open source code in python (gnssrefl) that allows users to measure either water levels or snow accumulation using GNSS data. This session will be devoted to helping users understand how to run and install the code. Please see the github (https://github.com/kristinemlarson/gnssrefl) repository for some tips on how to install the gnssrefl package on your local machine. We currently support the python code on linux and macs, with docker images for these and PCs. We also have links to jupyter notebooks. There is a complementary web app at https://gnss-reflections.org.

analogue missions, where future crewed or robotic space exploration
missions are simulated and evaluated towards their performance.
With increasing popularity of analogue planetary simulations as
test-beds to develop and test technologies, techniques and operational
procedures for planetary missions in facilities such as HiSeas, MDRS,
LunAres, AATC, MMAARS or similar facilities, this session invites
contributions in the field of analogue planetary research including, but
not limited to:
- data analysis about sites for future exploration
- results and lessons-learned from Lunar / Martian analogue missions
- instruments development for analogue and space research
- field tests for space exploration hardware, software and techniques

Remote sensing techniques, such as radar (e.g., synthetic aperture radar - SAR), optical, Lidar and hyperspectral imagery, together with hydroclimatic, geological, and geophysical data, as well as in-situ observations, have been widely employed for monitoring, and responding to natural and anthropogenic hazards and assessing environmental resources. Especially with the unprecedented spatio-temporal resolution and the rapid accumulation of remote sensing data collections from various spaceborne and airborne missions, we have much more opportunities to exploit hazard- and environmental- related signals, to classify the associated spatio-temporal surface changes such as deformations and landform alterations, and to interpret the primary and secondary driving mechanisms. Yet, when archiving, processing, and analyzing abundant remote sensing data, the ad hoc artificial intelligence (AI), like machine/deep learning and computer vision, is urgently required.
In this session, we welcome contributions that focus on new AI-based algorithms to retrieve remote sensing products related to environmental resources and hazards in an accurate, automated, and efficient framework. We particularly welcome contributions for applications in (1) mining, oil/gas production, fluid injection/extraction, civil infrastructure, sinkholes, land degradation, peatlands, glaciers, permafrost, and coastal subsidence; (2) emergency response based on remote sensing data to landslides, floods, winter storms, wildfires, pandemics, earthquakes, and volcanoes; and (3) mathematical and physical modeling of the remote sensing products for a better understanding on the surface and subsurface processes.

The increase of climate-related hazards has been driven by climate change, increasing human activities and infrastructure development, particularly in vulnerable areas. More efforts should be directed towards effective disaster risk management to reduce damages and losses, focusing on hazard, vulnerability, and risk mapping. Remote Sensing (RS) and Geographic Information Systems (GIS) are powerful tools in mapping change and rate of change concerning natural hazards, particularly in data-scarce environments, thanks to the great advantage of sensing extended areas at low cost and with regular revisit capability. Furthermore, satellite RS offers the opportunity to gain fresh insights into biophysical environments through satellite systems' spatial, temporal, spectral, and radiometric resolutions. The advantages of RS are further supported by the analytical and geospatial data integration capabilities of GIS.
On the other hand, proximal RS offers a unique opportunity to observe processes characterized by fast dynamics and complex geometries and provides data at ultra-high temporal and spatial resolution. The number of proximal RS solutions currently adopted to study and monitor natural hazards has progressively increased in the last decades. Nowadays, UAV, terrestrial radar interferometry, and digital photogrammetry are among the most diffuse proximal systems adopted to identify precursor elements for detailed hazard assessment and support decision-makers during emergencies. In particular, the use of these systems helps create high-resolution 3D models of the study area and monitor natural hazards. The adoption of multi-scale and multi-sensor approaches can be beneficial for studying the same phenomenon from different points of view and can support a detailed description of the studied process and the most critical parameters that can be adopted for its characterization. The availability of many technical solutions represents an additional value, but the lack of defined methodologies can limit these systems' standardized use, particularly during emergencies. This session aims to explore the use of satellite and proximal RS techniques and GIS analysis in different scenarios related to natural hazards and impact analysis and mitigation, including the preliminary characterization of potential dangerous processes, the evaluation of the elements at risk, the management of the emergency phase and the support of recovery and post-emergency reconstruction.
Synthetic aperture radar (SAR) remote sensing is an established tool for natural and anthropogenic hazards mapping and monitoring. The new generation of radar satellite constellations along with a consistent repository of historical observations is fostering comprehensive multi-sensor hazard analyses. New constellations’ capabilities rely on innovative techniques based on high-resolution/wide-swath and short-temporal Interferometric SAR (InSAR). While acknowledging the benefits brought by these recent developments, the scientific community is now defining a new paradigm of techniques capable of: extracting relevant information from SAR imagery, designing proper methodologies for specific hazards, managing large SAR datasets (e.g. National ground motion services, Copernicus EGMS), and integrating radar data with multispectral satellite observations.

Remote sensing and Earth Observations (EO) are used increasingly in the different phases of the risk management and in development cooperation, due to the challenges posed by contemporary issues such as climate change, and increasingly complex social interactions. The advent of new, more powerful sensors and more finely tuned detection algorithms provide the opportunity to assess and quantify natural hazards, their consequences, and vulnerable regions, more comprehensively than ever before.
Several agencies have now inserted permanently into their program the applications of EO data to risk management. During the preparedness and prevention phase, EO revealed, fundamental for hazard, vulnerability, and risk mapping. EO data intervenes both in the emergency forecast and early emergency response, thanks to the potential of rapid mapping. EO data is also increasingly being used for mapping useful information for planning interventions in the recovery phase, and then providing the assessment and analysis of natural hazards, from small to large regions around the globe. In this framework, Committee on Earth Observation Satellites (CEOS) has been working from several years on disasters management related to natural hazards (e.g., volcanic, seismic, landslide and flooding ones), including pilots, demonstrators, recovery observatory concepts, Geohazard Supersites, and Natural Laboratory (GSNL) initiatives and multi-hazard management projects.
The session is dedicated to multidisciplinary contributions focused on the demonstration of the benefit of the use of EO for natural hazards and risk management.
The research presented might focus on:
- Addressed value of EO data in hazard/risk forecasting models
- Innovative applications of EO data for rapid hazard, vulnerability and risk mapping, the post-disaster recovery phase, and in support of disaster risk reduction strategies
- Development of tools for assessment and validation of hazard/risk models
The use of different types of remote sensing (e.g. thermal, visual, radar, laser, and/or the fusion of these) is highly recommended, with an evaluation of their respective pros and cons focusing also on future opportunities (e.g. new sensors, new algorithms).
Early-stage researchers are strongly encouraged to present their research. Moreover, contributions from international cooperation, such as CEOS and GEO initiatives, are welcome.

Geomorphometry, a science of quantitative land surface analysis, gathers various mathematical, statistical and image processing techniques to quantify morphological, hydrological, ecological and other aspects of a land surface. The typical input to geomorphometric analysis is a square-grid representation of the land surface: a digital elevation model (DEM) or one of its derivatives. DEMs provide the backbone for many studies in Geo sciences, hydrology, land use planning and management, Earth observation and natural hazards.
One topic of active research concerns compromises between the use of global DEMs at 1-3 arc second, ~30-90 m grid spacing, and local LiDAR/structure from motion (SFM) elevation models at 1 m or finer grid spacing. Point clouds from LiDAR, either ground-based or from airborne vehicles, are a generally accepted reference tool to assess the accuracy of other DEMs. SFM data have a resolution comparable to LiDAR point clouds, but can cost significantly less to acquire for smaller areas. Globally available DEMS include the recently published Copernicus GLO-90 and GLO-30. This session provides an exciting forum to show the potential applications of this new DEM and its improvements over SRTM. We would like to investigate the tradeoff between the employment of the two kinds of data, and applications which can benefit from data at both (local and global) scales.
The improvements in the global DEMs, as well as the increasing availability of much finer resolution LiDAR and SFM DEMs, call for new analytical methods and advanced geo-computation techniques, necessary to cope with diverse application contexts. We aim at investigating new methods of analysis and advanced geo-computation techniques, including high-performance and parallel computing implementations of specific approaches.
Commercial applications of DEM data and of geomorphometric techniques can benefit important business sectors. Besides a proliferation of applications that can tolerate low accuracy geographical data and simple GIS applications, a large base of professionals use high-resolution, high-accuracy elevation data and high-performance GIS processing. We would like to survey and investigate professional, commercial and industrial applications, including software packages, from small enterprises to large companies, to ascertain how academic researchers and industry can work together.

This session invites contributions on the latest developments and results in lidar remote sensing of the atmosphere, covering • new lidar techniques as well as applications of lidar data for model verification and assimilation, • ground-based, airborne, and space-borne lidar systems, • unique research systems as well as networks of instruments, • lidar observations of aerosols and clouds, thermodynamic parameters and wind, and trace-gases. Atmospheric lidar technologies have shown significant progress in recent years. While, some years ago, there were only a few research systems, mostly quite complex and difficult to operate on a longer-term basis because a team of experts was continuously required for their operation, advancements in laser transmitter and receiver technologies have resulted in much more rugged systems nowadays, many of which are already operated routinely in networks and some even being automated and commercially available. Consequently, also more and more data sets with very high resolution in range and time are becoming available for atmospheric science, which makes it attractive to consider lidar data not only for case studies but also for extended model comparison statistics and data assimilation. Here, ceilometers provide not only information on the cloud bottom height but also profiles of aerosol and cloud backscatter signals. Scanning Doppler lidars extend the data to horizontal and vertical wind profiles. Raman lidars and high-spectral resolution lidars provide more details than ceilometers and measure particle extinction and backscatter coefficients at multiple wavelengths. Other Raman lidars measure water vapor mixing ratio and temperature profiles. Differential absorption lidars give profiles of absolute humidity or other trace gases (like ozone, NOx, SO2, CO2, methane etc.). Depolarization lidars provide information on the shapes of aerosol and cloud particles. In addition to instruments on the ground, lidars are operated from airborne platforms in different altitudes. Even the first space-borne missions are now in orbit while more are currently in preparation. All these aspects of lidar remote sensing in the atmosphere will be part of this session.

The Open Session on atmosphere, land and ocean monitoring aims at presenting highlights of recent results obtained through observations and modelling as well as relevant reviews in these fields.
We shall connect with Earth Observations programmes at ESA, EU and worldwide, using new satellites and oberving platforms, as well as new techniques for distributing, merging and analysing EO data using AI.
The session is intended as an open forum for interdisciplinary discussion between representatives of different fields. Thus, we welcome especially overarching presentations which may be interesting to a wider community.
Observations are one major link to get an overall picture of processes within the Earth environment during measurement campaigns. This includes application to derive atmospheric parameters, surface properties of vegetation, soil and minerals and dissolved or suspended matter in inland water and the ocean. Ground based systems and data sets from ships, aircraft and satellites are key information sources to complement the overall view. All of these systems have their pros and cons, but a comprehensive view of the observed system is generally best obtained by means of a combination of all of them.
The validation of operational satellite systems and applications is a topic that has come increasingly into focus with the European Copernicus program in recent years. The development of smaller state-of-the-art instruments, the combination of more and more complex sets of instruments simultaneously on one platform, with improved accuracy and high data acquisition speed together with high accuracy navigation and inertial measurements enables more complex campaign strategies even on smaller aircraft or unmanned aerial vehicles (UAV).
This session will bring together a multidisciplinary research community to present:
• Atmosphere-land-ocean (or inland water) system modelling and validation
• new instruments (Lidar, etc), platforms (UAV etc.), setups and use in multidisciplinary approaches
• Larger scale in-situ and remote sensing observation networks from various platforms (ground based, airborne, ship-borne, satellite)
• recent field campaigns and their outcomes
• (multi-) aircraft campaigns
• satellite calibration/validation campaigns
• sophisticated instrument setups and observations
• advanced instrument developments
• UAV applications

The never-ending growth of the ground penetrating radar applications reserves continuously small and less small discoveries, and deserves a space for discussion and reciprocal listening also at the EGU conference.
The pandemic has meaningfully hindered many activities but to our knowledge not too much the interest in the GPR instrumentation and technique at an applicative level, even if exchanges of experiences at international conferences have been of course necessarily reduced. So, we hope that this session can meet the interest of many researchers, professionals, PhD students as well skilled GPR users as geologists, engineers, geophysicists and possibly archaeologists and architects.
Contributions are welcome with regard to all the aspects of the GPR technique, ranging from the hardware of the systems to the data processing and any theoretical aspect, including innovative applications or procedures as well as results of particular relevance, possibly achieved within an integrated measurement campaign including also different data.
Hope to see you in Vienna.

Continues monitoring of infrastructure systems are essential to ensure a reliable movement of people and goods, which involves in the economy growth and human interaction. The wide variety of instruments available allows diverse applications to increase data availability for a better understanding of geotechnical surroundings which are directly linked to the safe operation of infrastructures to prevent catastrophise such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding and even wildfires close to the highways. Understanding mentioned events are vital to provide a safe infrastructure in extreme climate conditions. This session focus on the application of geosciences and geophysical instrumentation including sensors on the infrastructures monitoring and data analysis from critical infrastructures (e.g., roadways, railway system, bridges, tunnels, water supply, underground utilities, electrical grids, and other embedded facilities in cities). The session aims to increase knowledge on geo-infrastructure management to overcome future challenges associated with the societal and human interaction, present advance knowledge research and novel approaches from various disciplines with a vibrant interaction to economy and human-interaction studies to provide an efficient infrastructure management system. The session is considered inter-and transdisciplinary (ITS) session. The applications and topics include but are not limited to: (1) Advance knowledge of the destructive and non-destructive geoscience and geophysical techniques including contactless and non-contactless techniques such as sensors. (2) Intelligent data analysis approaches to analyse accurate and precise interpretation of big data sets driven from various technologies (e.g., computer vision and image, and signal processing). (3) Influence of the surrounding areas on infrastructure management systems linked to natural events such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding, wildfires and extreme weather condition. (4) Continuous real-time monitoring to provide smart tools such as an integration of geosciences data with BIM models, Internet of Things, digital twins, robotic monitoring, artificial intelligence, automation systems based on machine learning and computational modelling for better decision-making for infrastructure owner/operators. (5) Human-interaction computer-based aided to generate reliable infrastructures.
Since the beginning of the XXI Century, our society has witnessed a number of catastrophic offshore earthquakes with devastating consequences (e.g., Sumatra 2004, Japan 2010, Palu 2018 or Samos-Izmir 2020). Localizing the offshore active faults and understanding their earthquake history is key to improve modern probabilistic seismic hazard assessment (PSHA) and, thus, to be able to mitigate the consequences of future offshore events.
In the last few years, the development of new geological and geophysical instrumentation has made possible the acquisition of offshore data at various scales with unprecedented detail and resolution, as for example deep and shallow boreholes, wide-angle seismic profiles, tomography, 3D and 2D seismic reflection surveys, or ultra-high-resolution bathymetry. In addition, these instrumentation is also allowing to carry on long-term monitoring (i.e., seismology, seafloor geodesy or pore pressure) and repeat surveys (i.e., time-lapse bathymetry). These new data is leading to achieve major advances in the study of active faults in offshore areas and the characterization of their recent activity, seismogenic potential and related secondary effects (i.e., mass wasting).
The aim of this session is to compile studies that focus on the use of geological and geophysical data to identify offshore active structures, to quantify the deformation that they are producing in the seafloor, to evaluate their seismogenic and tsunamigenic potential, to characterize possibly related secondary effects such as submarine mass transport deposits, and to estimate the related hazards. Accordingly, we welcome studies and/or new perspectives and ideas in marine active tectonics, turbidite paleoseismology, offshore on-fault paleoseismology or tectonic geomorphology, and seismotectonics, from local to regional scale analysis. We also encourage the submission of studies that explore the application of new ideas to estimate coseismic seafloor deformation, to constrain earthquake timing, long-term offshore monitoring of active structures, as well as the application of fault geometrical and kinematic reconstruction to seismic and tsunami hazard analysis.

Regular talks will have 7 minutes each (5 presentation + 2 questions). Invited talk (Prof. Micheal Strasser) will have 10 minutes for the talk followed by a 12 minutes period for questions, discussion and closing of the session.

Recently, there have been significant breakthroughs in the use of fiber-optic sensing techniques to interrogate cables at high precision both on land and at sea as well as in boreholes and at the surface. Laser reflectometry using both fit-to-purpose and commercial fiber-optic cables have successfully detected a variety of signals including microseism, local and teleseismic earthquakes, volcanic events, ocean dynamics, etc. Other laser-based techniques can be used to monitor distributed strain, temperature, and even chemicals at a scale and to an extent previously unattainable with conventional geophysical methods.
We welcome any contributions to recent development in the fields of applications, instrumentation, and theoretical advances for geophysics with fiber-optic sensing techniques. These may include - but are not limited to - application of fiber-optic cables or sensors in seismology, geodesy, geophysics, natural hazards, oceanography, urban environment, geothermal application, etc. with an emphasis on laboratory studies, large-scale field tests, and modeling. We also encourage contributions on data analysis techniques, machine learning, data management, instruments performances and comparisons as well as new experimental field studies.
Geophysical and in-situ measurements offer important baseline datasets, as well as validation for modelling and remote sensing products. They are used to advance our understanding of firn, ice-sheet and glacier dynamics, sea ice processes, changes in snow cover and snow properties, snow/ice-atmosphere-ocean interactions, permafrost degradation, geomorphic mechanisms and changes in englacial and subglacial condition.
In this session we welcome contributions related to a wide spectrum of methods, including, but not limited to, advances in radioglaciology, active and passive seismology, geoelectrics, acoustic sounding, fiber-optic sensing, GNSS reflectometry, signal attenuation and time delay techniques, cosmic ray neutron sensing, ROV and drone applications, and electromagnetic methods. Contributions could be related to field applications, new approaches in geophysical or in-situ survey techniques, or theoretical advances in data analysis processing or inversion. Case studies from all parts of the cryosphere such as snow and firn, alpine glaciers, ice sheets, glacial and periglacial environments, permafrost, or sea ice, are highly welcome.
The focus of the session is to compare experiences in the application, processing, analysis and interpretation of different geophysical and in-situ techniques in these highly complex environments. We have been running this session for nearly a decade and it always produces lively and informative discussion. This session is offered as a fully hybrid vPICO: an engaging presentation format in which all authors will present their research orally as a quick-fire 2-minute overview, and then further present and discuss their research.

From the real-time integration of multi-parametric observations is expected the major contribution to the development of operational t-DASH systems suitable for supporting decision makers with continuously updated seismic hazard scenarios. A very preliminary step in this direction is the identification of those parameters (seismological, chemical, physical, biological, etc.) whose space-time dynamics and/or anomalous variability can be, to some extent, associated with the complex process of preparation of major earthquakes.
This session wants then to encourage studies devoted to demonstrate the added value of the introduction of specific, observations and/or data analysis methods within the t-DASH and StEF perspectives. Therefore, studies based on long-term data analyses, including different conditions of seismic activity, are particularly encouraged. Similarly welcome will be the presentation of infrastructures devoted to maintain and further develop our present observational capabilities of earthquake related phenomena also contributing in this way to build a global multi-parametric Earthquakes Observing System (EQuOS) to complement the existing GEOSS initiative.
To this aim this session is not addressed just to seismology and natural hazards scientists but also to geologist, atmospheric sciences and electromagnetism researchers, whose collaboration is particular important for fully understand mechanisms of earthquake preparation and their possible relation with other measurable quantities. For this reason, all contributions devoted to the description of genetic models of earthquake’s precursory phenomena are equally welcome.

Rockfalls, rockslides and rock avalanches are among the primary hazards and drivers of landscape evolution in steep terrain. The physics of rock slope degradation and dynamics of failure and transport mechanisms define the hazards and possible mitigation strategies and enable retrodictions and predictions of events and controls.
This session aims to bring together state-of-the-art methods for predicting, assessing, quantifying, and protecting against rock slope hazards across spatial and temporal scales. We seek innovative contributions from investigators dealing with all stages of rock slope hazards, from weathering and/or damage accumulation, through detachment, transport and deposition, and finally to the development of protection and mitigation measures. In particular, we seek studies presenting new theoretical, numerical or probabilistic modelling approaches, novel data sets derived from laboratory, in situ, or remote sensing applications, and state-of-the-art approaches to social, structural, or natural protection measures. We especially encourage contributions from geomechanics/rock physics, geodynamics, geomorphology and tectonics to better understand how rockfall, rockslides and rock avalanches act across scales.

Among the many mitigation measures available for reducing the risk to life related to landslides, early warning systems certainly constitute a significant option available to the authorities in charge of risk management and governance. Landslide early warning systems (LEWS) are non-structural risk mitigation measures applicable at different scales of analysis: slope and regional.
Independently by the scale of analysis, the structure of LEWS can be schematized as an interrelation of four main modules: setting, modelling, warning, response. However, the definition of the elements of these modules and the aims of the warnings/alerts issued considerably vary as a function of the scale at which the system is employed.
The session focuses on landslide early warning systems (LEWSs) at both regional and local scales. The session wishes to highlight operational approaches, original achievements and developments useful to operate reliable (efficient and effective) local and territorial LEWS. Moreover, the different schemes describing the structure of a LEWS available in literature clearly highlight the importance of both social and technical aspects in the design and management of such systems.
For the above-mentioned reasons, contributions addressing the following topics are welcome:
• rainfall thresholds definition for warning purposes;
• monitoring systems for early warning purposes;
• warning models for warning levels issuing;
• performance analysis of landslide warning models;
• communication strategies;
• emergency phase management;

This session is devoted to the most recent eruption of the Cumbre Vieja volcano, which started on Sept. 19, 2021, on the island of La Palma after 50 years of repose. Volcanic unrest was recorded in Oct. 2017, when a seismic swarm was located at more than 20 km depths. Nine additional swarms followed, the last one was recorded in June 2021. Geochemical anomalies followed this increased seismicity indicating a magmatic recharge at depth. On Sept. 11, 2021, a new seismic swarm was observed at shallower depths (10-12 km), indicating a possible magmatic intrusion. This was confirmed when geodetic monitoring networks on the island started showing clear signs of inflation. The seismicity increased in frequency and intensity with many felt earthquakes. Seismic activity accelerated in the morning of Sept. 19 when a strong shallow earthquake was widely felt on the western part of the island. This was the precursor of the eruption, which started at about 14:10 UTC on the same day. A series of vents opened along a fissure close to Los Llanos on the western flank of Cumbre Vieja volcano. The eruption displayed vigorous lava fountaining and powerful Strombolian explosions while lava effusion produced a compound Aa flow field. The eruption has destroyed hundreds of buildings, plantations as well as cutting vital transport routes.
This session is open to contributions aimed at geological, geophysical, geochemical and volcanological studies of the eruption and its precursors and, more in general, to studies that can help better understanding the eruptive dynamics. We also welcome contributions focused on the management of scientific communication during this crisis and the management of the volcanic emergency.

Transport of sediments in geophysical flows occurs in mountainous, fluvial, estuarine, coastal, aeolian and other natural or man-made environments on Earth, while also shapes the surface of planets such as Mars, Titan, and Venus. Understanding the motion of sediments is still one of the most fundamental problems in hydrological and geophysical sciences. Such processes can vary across a wide range of scales - from the particle to the landscape - which can directly impact both the form (geomorphology) and, on Earth, the function (ecology and biology) of natural systems and the built infrastructure surrounding them. In particular, feedback between flow and sediment transport as well as interparticle interactions including size sorting are a key processes in surface dynamics, finding a range of important applications, from hydraulic engineering and natural hazard mitigation to landscape evolution and river ecology.
Specific topics of interest include (but are not restricted to):
A) particle-scale interactions and transport processes:
-mechanics of entrainment and disentrainment (for fluvial and aeolian flows)
-momentum (turbulent impulses) and energy transfer between turbulent flows and particles
-upscaling and averaging techniques for stochastic transport processes
-interaction among grain sizes in poorly sorted mixtures, including particle segregation
B) reach-scale sediment transport and geomorphic processes
-bedform generation, evolution and disintegration dynamics (e.g. for dunes and other formations)
-discrete element modelling of transport processes and upscaling into continuum frameworks
-derivation and solution of equations for multiphase flows (including fluvial and aeolian flows)
-shallow water hydro-sediment-morphodynamic processes
C) large-scale, highly unsteady and complex water-sediment flows:
-flash floods, debris flows and landslides due to extreme rainfall

Sediment transport is a fundamental component of all geomorphic systems (including fluvial, aeolian, coastal, hillslopes and glacial), yet it is something that we still find surprisingly difficult both to monitor and to model. Robust data on where and how sediment transport occurs are needed to address outstanding research questions, including the spatial and temporal controls on critical shear stress, the influence of varying grain size distributions, and the impact of large magnitude events. Recent developments have provided a) new opportunities for measuring sediment transport in the field; and b) new ways to represent sediment transport in both physical laboratory models and in numerical models. These developments include (but are not limited to) the application of techniques such as seismic and acoustic monitoring, 3D imaging (e.g. CT and MRI scanning), deployment of sensors such as accelerometers, replication of field topography using 3D printing, use of luminescence as a sediment tracer, remote sensing of turbidity, discrete numerical modelling, and new statistical approaches.
In this session we welcome contributions from all areas of geomorphology that develop new methods for monitoring and modelling all types of sediment transport, or that showcase an application of such methods. Contributions from ECRs and underrepresented groups are particularly encouraged.

Remote sensing measurements, acquired using different platforms - ground, UAV, aircraft and satellite - have increasingly become rapidly developing technologies to study and monitor Earth surface, to perform comprehensive analysis and modeling, with the final goal of supporting decision systems for ecosystem management. The spectral, spatial and temporal resolutions of remote sensors have been continuously improving, making environmental remote sensing more accurate and comprehensive than ever before. Such progress enables understanding of multiscale aspects of high-risk natural phenomena and development of multi-platform and inter-disciplinary surveillance monitoring tools. The session welcomes contributions focusing on present and future perspectives in environmental remote sensing, from multispectral/hyperspectral optical and thermal sensors. Applications are encouraged to cover, but not limited to, the monitoring and characterization of environmental changes and natural hazards from volcanic and seismic processes, landslides, and soil science. Specifically, we are looking for novel solutions and approaches including the topics as follows: (i) state-of-the-art techniques focusing on novel quantitative methods; (ii) new applications for state-of-the-art sensors, including UAVs and other close-range systems; (iii) techniques for multiplatform data fusion.
Observations from aircraft, remotely piloted aircraft systems (RPAS/UAV/UAS) and balloons are an important means to obtain a broad view of processes within the Earth environment during measurement campaigns. The range of available instruments enables a broad and flexible range of applications. It includes sensors for meteorological parameters, trace gases and cloud/aerosol particles and more complex systems like high spectral resolution lidar, hyperspectral imaging at wavelengths from the visible to thermal infra-red, solar-induced fluorescence and synthetic aperture radar. The use of small state-of-the-art instruments, the combination of more and more complex sets of instruments with improved accuracy and data acquisition speed enables more complex campaign strategies even on small aircraft, balloons or RPAS.
Applications include atmospheric parameters, structural and functional properties of vegetation, glaciological processes, sea ice and iceberg studies, soil and minerals and dissolved or suspended matter in inland water and the ocean. Ground based systems and satellites are key information sources to complement airborne datasets and a comprehensive view of the observed system is often obtained by combining all three. Aircraft and balloon operations depend on weather conditions either to obtain the atmospheric phenomenon of interest or the required surface-viewing conditions and so require detailed planning. They provide large horizontal and vertical coverage with adaptable temporal sampling. Future satellite instruments can be tested using airborne platforms during their development. The validation of operational satellite systems and applications using airborne measurements has come increasingly into focus with the European Copernicus program in recent years.
This session will bring together aircraft, balloon and RPAS operators and researchers to present:
• an overview of the current status of environmental research focusing on the use of airborne platforms
• recent observation campaigns and their outcomes
• multi-aircraft/balloon/RPAS and multi-RI campaigns
• using airborne and ground-based RI to complement satellite data, including cal/val campaigns
• identifying and closing capability gaps
• contributions of airborne measurements to modelling activities
• airborne platforms to reduce the environmental footprint of alternative observation strategies
• airborne instruments, developments and observations
• future plans involving airborne research

Environmental systems often span spatial and temporal scales covering different orders of magnitude. The session is oriented toward collecting studies relevant to understand multiscale aspects of these systems and in proposing adequate multi-platform and inter-disciplinary surveillance networks monitoring tools systems. It is especially aimed to emphasize the interaction between environmental processes occurring at different scales. In particular, special attention is devoted to the studies focused on the development of new techniques and integrated instrumentation for multiscale monitoring of high natural risk areas, such as volcanic, seismic, energy exploitation, slope instability, floods, coastal instability, climate changes, and another environmental context.
We expect contributions derived from several disciplines, such as applied geophysics, geology, seismology, geodesy, geochemistry, remote and proximal sensing, volcanology, geotechnical, soil science, marine geology, oceanography, climatology, and meteorology. In this context, the contributions in analytical and numerical modeling of geological and environmental processes are also expected.
Finally, we stress that the inter-disciplinary studies that highlight the multiscale properties of natural processes analyzed and monitored by using several methodologies are welcome.

Cosmic rays carry information about space and solar activity, and, once near the Earth, they produce isotopes, influence genetic information, and are extraordinarily sensitive to water. Given the vast spectrum of interactions of cosmic rays with matter in different parts of the Earth and other planets, cosmic-ray research ranges from studies of the solar system to the history of the Earth, and from health and security issues to hydrology and climate change.
Although research on cosmic-ray particles is connected to a variety of disciplines and applications, they all share similar questions and problems regarding the physics of detection, modeling, and the influence of environmental factors.
The session brings together scientists from all fields of research that are related to monitoring and modeling of cosmogenic radiation. It will allow sharing of expertise amongst international researchers as well as showcase recent advancements in their field. The session aims to stimulate discussions about how individual disciplines can share their knowledge and benefit from each other.
We solicit contributions related but not limited to:
- Health, security, and radiation protection: cosmic-ray dosimetry on Earth and its dependence on environmental and atmospheric factors
- Planetary space science: satellite and ground-based neutron and gamma-ray sensors to detect water and soil constituents
- Neutron and Muon monitors: detection of high-energy cosmic-ray variations and its dependence on local, atmospheric, and magnetospheric factors
- Hydrology and climate change: low-energy neutron sensing to measure water in reservoirs at and near the land surface, such as soils, snow pack, and vegetation
- Cosmogenic nuclides: as tracers of atmospheric circulation and mixing; as a tool in archaeology or glaciology for dating of ice and measuring ablation rates; and as a tool for surface exposure dating and measuring rates of surficial geological processes
- Detector design: technological advancements for the detection of cosmic rays
- Cosmic-ray modeling: advances in modeling of the cosmic-ray propagation through the magnetosphere and atmosphere, and their response to the Earth's surface
- Impact modeling: How can cosmic-ray monitoring support environmental models, weather and climate forecasting, irrigation management, and the assessment of natural hazards

Natural radioactivity is ubiquitous in the environment as a result of i) cosmic radiation from space and secondary radiation from the interaction of cosmic rays with the atmosphere, ii) terrestrial sources from soils and rocks and particularly Potassium, Uranium and Thorium and their decay products among which Radon gas stands out. Artificial radionuclides from nuclear and radiation accidents and incidents makes up an additional contribution to the environmental radioactivity.
Nuclear techniques enable the measurement of radioactivity in air, soils and water even at trace levels, making it a particularly appealing tool for tracing time-varying environmental phenomena. This session welcomes contributions addressing the measurement and exploitation of environmental radioactivity in all areas of geosciences, including, but not limited to:
- geological and geomorphological surveys;
- mineral exploration;
- groundwater contamination;
- coastal and marine monitoring;
- soil erosion processes;
- Naturally Occurring Radioactive Materials (NORMs);
- geostatistical methods for radioactivity mapping;
- airborne and drones surveys;
- novel methods and instrumentations;

This combined session aims to provide extensive overview of different methodologies applied to pursue the achievement of one or more Sustainable Development Goals as well as to address issues related to national GHG reporting.
In one part session includes submissions related to global or regional applications of geospatial data analysis techniques to address sustainability challenges (land, energy, water, climate, infrastructure, vegetation, health etc.) and their interactions. Contributions aiming at improving the understanding, planning, and evaluation of technological, environmental and policy solutions pursuing the achievement of one or more Sustainable Development Goals (SDGs) will be considered. The main methodological requirement is the use of GIS data (from earth observation, in-situ collection, or statistical offices) and manipulation tools to develop and apply innovative methodologies leveraging bottom-up, spatially-explicit information and highlighting their benefits vis-à-vis aggregated, top-down analysis. Preference will be given to studies which are broader in geographical scope, and which can be scaled to other contexts.
Also, session will emphasize the importance of LULUCF sector in reaching the long-term climate mitigation objective. Contributions related to national and subnational carbon budget estimates (past, present and future) in different land uses (forests, crops, grasslands, urban areas), using multiple data sources and different calculation methods, will be considered. NFI-based, remote sensing and modelling studies on C stocks and/or fluxes in different ecosystem pools (live biomass, dead wood, litter or soil) are encouraged. Aim is to highlight main issues regarding data integration and model calibration and validation process.
Recent advances in image collection, e.g. using unoccupied aerial vehicles (UAVs), and topographic measurements, e.g. using terrestrial or airborne LiDAR, are providing an unprecedented insight into landscape and process characterization in geosciences. In parallel, historical data including terrestrial, aerial, and satellite photos as well as historical digital elevation models (DEMs), can extend high-resolution time series and offer exciting potential to distinguish anthropogenic from natural causes of environmental change and to reconstruct the long-term evolution of the surface from local to regional scale.
For both historic and contemporary scenarios, the rise of techniques with ‘structure from motion’ (SfM) processing has democratized data processing and offers a new measurement paradigm to geoscientists. Photogrammetric and remote sensing data are now available on spatial scales from millimetres to kilometres and over durations of single events to lasting time series (e.g. from sub-second to decadal-duration time-lapse), allowing the evaluation of event magnitude and frequency interrelationships.
The session welcomes contributions from a broad range of geoscience disciplines such as geomorphology, cryosphere, volcanology, hydrology, bio-geosciences, and geology, addressing methodological and applied studies. Our goal is to create a diversified and interdisciplinary session to explore the potential, limitations, and challenges of topographic and orthoimage datasets for the reconstruction and interpretation of past and present 2D and 3D changes in different environments and processes. We further encourage contributions describing workflows that optimize data acquisition and processing to guarantee acceptable accuracies and to automate data application (e.g. geomorphic feature detection and tracking), and field-based experimental studies using novel multi-instrument and multi-scale methodologies. This session invites contributions on the state of the art and the latest developments in i) modern photogrammetric and topographic measurements, ii) remote sensing techniques as well as applications, iii) time-series processing and analysis, and iv) modelling and data processing tools, for instance, using machine learning approaches.

Landscapes, and how they change over time, provide the foundations of life and affect the ecosystems and human activities that can exist on Earth. Yet, there appears to be no single axis of causality between landscape and Earth surface processes, but rather, each entity can exert a simultaneous influence on the other over a wide range of temporal and spatial scales. We are just starting to realise and explore the modes, trajectories and effects of these coupled systems, and to trace and infer the often non-linear feedback mechanisms.
Geomorphology inevitably stands in the center of an emerging science devoted to the Earth's surface, where strong couplings link human dynamics, biology, biochemistry, geochemistry, geology, hydrology, geomorphology, soil science, and atmospheric dynamics, including past and ongoing climate changes.
Motivated by the importance of understanding Earth surface interactions, couplings and feedbacks on a rapidly changing globe, this session will bring together a series of invited speakers to provide insights and perspectives on this hot topic from across the field of geomorphology.

Flash floods triggered by heavy precipitation in small- to medium-sized catchments often cause catastrophic damages, which are largely explained by the very short response times and high specific peak discharge. Often, they are also associated with geomorphic processes such as erosion, sediment transport, debris flows and shallow landslides. The anticipation of such events is crucial for efficient crisis management. However, their predictability is still affected by large uncertainties, due to the fast evolution of triggering rainfall events, the lack of appropriate observations, the high variability and non-linearity in the physical processes, the high variability of societal exposure, and the complexity of societal vulnerability.
This session aims to illustrate current advances in monitoring, modeling, and short-range forecasting of flash floods and associated geomorphic processes, including their societal impacts.
Contributions related to the floods that occured in July 2021 in Germany and Western Europe, and in October 2020 in France and Italy (Alex storm) are particularly encouraged this year.
Contributions on the following scientific themes are specifically expected:
- Monitoring and nowcasting of heavy precipitation events based on radar and remote sensing (satellite, lightning, etc.) to complement rain gauge networks;
- Short-range (0-6h) heavy precipitation forecasting based on NWP models, with a focus on seamless forecasting strategies and ensemble strategies for the representation of uncertainties;
- Understanding and modeling of flash floods and associated geomorphic processes at appropriate space-time scales;
- Development of integrated hydro-meteorological forecasting chains and new modeling approaches for predicting flash floods and/or rainfall-induced geomorphic hazards in gauged and ungauged basins;
- New direct and indirect (proxy data) observation techniques and strategies for the observation or monitoring of hydrological reactions and geomorphic processes, and the validation of forecasting approaches;
- Development of impact-based modeling and forecasting approaches, including inundation mapping and/or specific impacts modeling approaches for the representation of societal vulnerability.

Transport of sediments in geophysical flows occurs in mountainous, fluvial, estuarine, coastal, aeolian and other natural or man-made environments on Earth, while also shapes the surface of planets such as Mars, Titan, and Venus. Understanding the motion of sediments is still one of the most fundamental problems in hydrological and geophysical sciences. Such processes can vary across a wide range of scales - from the particle to the landscape - which can directly impact both the form (geomorphology) and, on Earth, the function (ecology and biology) of natural systems and the built infrastructure surrounding them. In particular, feedback between flow and sediment transport as well as interparticle interactions including size sorting are a key processes in surface dynamics, finding a range of important applications, from hydraulic engineering and natural hazard mitigation to landscape evolution and river ecology.
Specific topics of interest include (but are not restricted to):
A) particle-scale interactions and transport processes:
-mechanics of entrainment and disentrainment (for fluvial and aeolian flows)
-momentum (turbulent impulses) and energy transfer between turbulent flows and particles
-upscaling and averaging techniques for stochastic transport processes
-interaction among grain sizes in poorly sorted mixtures, including particle segregation
B) reach-scale sediment transport and geomorphic processes
-bedform generation, evolution and disintegration dynamics (e.g. for dunes and other formations)
-discrete element modelling of transport processes and upscaling into continuum frameworks
-derivation and solution of equations for multiphase flows (including fluvial and aeolian flows)
-shallow water hydro-sediment-morphodynamic processes
C) large-scale, highly unsteady and complex water-sediment flows:
-flash floods, debris flows and landslides due to extreme rainfall
-natural and build dam failures and compound disasters (due to landslides, debris flow intrusion and downstream flooding)
-reservoir operation schemes and corresponding fluvial processes
-design of hydraulic structures such as fish passages, dam spillways, also considering the impact of sediment
-dredging, maintenance and regulation for large rivers and navigational waterways
Geomorphometry, a science of quantitative land surface analysis, gathers various mathematical, statistical and image processing techniques to quantify morphological, hydrological, ecological and other aspects of a land surface. The typical input to geomorphometric analysis is a square-grid representation of the land surface: a digital elevation model (DEM) or one of its derivatives. DEMs provide the backbone for many studies in Geo sciences, hydrology, land use planning and management, Earth observation and natural hazards.
One topic of active research concerns compromises between the use of global DEMs at 1-3 arc second, ~30-90 m grid spacing, and local LiDAR/structure from motion (SFM) elevation models at 1 m or finer grid spacing. Point clouds from LiDAR, either ground-based or from airborne vehicles, are a generally accepted reference tool to assess the accuracy of other DEMs. SFM data have a resolution comparable to LiDAR point clouds, but can cost significantly less to acquire for smaller areas. Globally available DEMS include the recently published Copernicus GLO-90 and GLO-30. This session provides an exciting forum to show the potential applications of this new DEM and its improvements over SRTM. We would like to investigate the tradeoff between the employment of the two kinds of data, and applications which can benefit from data at both (local and global) scales.
The improvements in the global DEMs, as well as the increasing availability of much finer resolution LiDAR and SFM DEMs, call for new analytical methods and advanced geo-computation techniques, necessary to cope with diverse application contexts. We aim at investigating new methods of analysis and advanced geo-computation techniques, including high-performance and parallel computing implementations of specific approaches.
Commercial applications of DEM data and of geomorphometric techniques can benefit important business sectors. Besides a proliferation of applications that can tolerate low accuracy geographical data and simple GIS applications, a large base of professionals use high-resolution, high-accuracy elevation data and high-performance GIS processing. We would like to survey and investigate professional, commercial and industrial applications, including software packages, from small enterprises to large companies, to ascertain how academic researchers and industry can work together.
Numerical frameworks are essential for understanding and interpreting landscape evolution. Over recent decades, geochronological techniques such as cosmogenic nuclides, thermochronology, radiocarbon and luminescence dating have improved in accuracy, precision, and temporal range. Developments in geochronological methods, data treatment and landscape evolution models have provided new insights into the timing, duration and intensity of landscape evolution processes. The combination of temporal constraints with numerical modelling has enormous potential for improving our understanding of landscape evolution. The focus of this session is to bring together geochronology, data science and models of Quaternary landscape change.
This session includes studies of erosional rates and processes, sediment provenance, burial and transport times, bedrock exposure or cooling histories, landscape dynamics, and the examination of potential biases and discordances in geochronological data and model-data comparisons. We welcome contributions that apply and combine novel geochronological methods and that intersect different geochronological techniques and numerical modelling with landscape evolution analysis. This includes the determination of rates and timing of landscape change as well as stochastic events, or that highlight the latest developments and open questions in the application of geochronometers to landscape evolution problems.

The introduction of cosmogenic nuclides in quantitative geomorphology and geochronology spurred large developments that transformed them into an essential tool in these fields. Cosmogenic nuclides can be used to provide important information on the exposure ages of features at the surface (e.g. river terraces, fault and landslide scarps, glacial moraines), burial ages of deep deposits, as well as quantitative information on the rates and evolution of surface processes (e.g. erosion, weathering, soil mixing), or even a tool for paleoaltimetry or paleotemperature. Continued technique development and creative applications expand the ways we can use cosmogenic nuclides.
This session explores both technique developments and novel applications of cosmogenic nuclides, inviting projects at any stage from early development to well-established methods applied to novel situations. We invite any type of cosmogenic nuclide technique developments, including new laboratory setup, measurement methods, laboratory techniques for extraction, modelling, or theoretical advancements. All cosmogenic nuclide applications in any field are welcome, and we especially encourage contributions using multiple nuclides, nuclides challenging for their extraction or interpretation (e.g. 3He, 36Ar, in situ 14C), combinations with other geochronology techniques, and other creative applications.
We aim herein to focus and illustrate all UAS/drone classical and new techniques and processing in order to study all Geological & Geomorphological objects in terms of 3D geometry (description and localisation, characterisation, quantification, modelisation...) in order to better constrained Earth Sciences processes.
Consequently, dealing with the technical point of view, it takes into account not only classical photogrammetric data processing through aerial photographs but also new techniques such as UAS-Lidar acquisition, and/or new UAS-interferometric acquisitions.
Many resulting dataset should be provided and discussed as key examples such as Very High Resolution Digital Terrain Model and/or Digital Surface Model (VHR DTM/DSM) less than 10cm ground resolution pixels that lead to acquire much more precise geometries, to up-date geological and geomorphological mapping and up-date structural scheme of geological targets. Many case examples could be listed herein such as analogs of sandstones or limestones reservoirs, active sedimentological processes in shoreline areas, or Natural Hazards processes such as landslides, etc...
For instance, in the active tectonic areas the HR UAS DTM may be combined with classical geodetic measurements such as levelings, numerous GPS and RTK surveys... and/or spatial PSInSAR, Smallbase line interferometric analyses in order to decipher and precise the active faults and folds structures and evenmore participate to determine the seismic cycles of major active faults.
We aim in this session to share our UAS/drone experiences on the various geological and geomorphological objects outcropping wherever the place of the Earth.
Recent advances in image collection, e.g. using unoccupied aerial vehicles (UAVs), and topographic measurements, e.g. using terrestrial or airborne LiDAR, are providing an unprecedented insight into landscape and process characterization in geosciences. In parallel, historical data including terrestrial, aerial, and satellite photos as well as historical digital elevation models (DEMs), can extend high-resolution time series and offer exciting potential to distinguish anthropogenic from natural causes of environmental change and to reconstruct the long-term evolution of the surface from local to regional scale.
For both historic and contemporary scenarios, the rise of techniques with ‘structure from motion’ (SfM) processing has democratized data processing and offers a new measurement paradigm to geoscientists. Photogrammetric and remote sensing data are now available on spatial scales from millimetres to kilometres and over durations of single events to lasting time series (e.g. from sub-second to decadal-duration time-lapse), allowing the evaluation of event magnitude and frequency interrelationships.
The session welcomes contributions from a broad range of geoscience disciplines such as geomorphology, cryosphere, volcanology, hydrology, bio-geosciences, and geology, addressing methodological and applied studies. Our goal is to create a diversified and interdisciplinary session to explore the potential, limitations, and challenges of topographic and orthoimage datasets for the reconstruction and interpretation of past and present 2D and 3D changes in different environments and processes. We further encourage contributions describing workflows that optimize data acquisition and processing to guarantee acceptable accuracies and to automate data application (e.g. geomorphic feature detection and tracking), and field-based experimental studies using novel multi-instrument and multi-scale methodologies. This session invites contributions on the state of the art and the latest developments in i) modern photogrammetric and topographic measurements, ii) remote sensing techniques as well as applications, iii) time-series processing and analysis, and iv) modelling and data processing tools, for instance, using machine learning approaches.
Geomorphometry and landform mapping are important tools used for understanding landscape processes and dynamics on Earth and other planetary bodies. The recent rapid advances in technology and data collection methods have made available vast quantities of geospatial data offering unprecedented spatio-temporal range, density, and resolution, but it also created new challenges in terms of data processing and analysis.
This inter-disciplinary session on geomorphometry and landform mapping aims to bridge the gap between process-focused research fields and the technical domain where geospatial products and analytical methods are developed. The increasing availability of a wide range of geospatial datasets requires the continued development of new tools and analytical approaches as well as landform/landscape classifications. However, a potential lack of communication across disciplines results in efforts to be mainly focused on problems within individual fields. We aim to foster collaboration and the sharing of ideas across subject-boundaries, between technique developers and users, enabling us as a community to fully exploit the wealth of geospatial data that is now available.
We welcome perspectives on geomorphometry and landform mapping from ANY discipline (e.g. geomorphology, planetary science, natural hazard assessment, computer science, remote sensing). This session aims to showcase both technical and applied studies, and we welcome contributions that present (a) new techniques for collecting or deriving geospatial data products, (b) novel tools for analysing geospatial data and extracting innovative geomorphometric variables, (c) mapping and/or morphometric analysis of specific landforms as well as whole landscapes, and (d) mapping and/or morphometric analysis of newly available geospatial datasets. Contributions that demonstrate multi-method or inter-disciplinary approaches are particularly encouraged. We also actively encourage contributors to present tools/methods that are “in development”.

One of the key challenges in earthquake geology is the characterization of the spatial distribution of fault-slip and its partitioning during the coseismic, interseismic, and post-seismic periods. We now have new approaches and techniques for validating the assumption that repeated seismic cycles accommodate the long-term tectonic strain and for disentangling such a complex strain partitioning in both time and space. In fact, the temporal and spatial slip accumulation for an active fault is essential to understand the hazard posed by the fault. As a matter of fact, destructive earthquakes are infrequent along any active fault and this is an inherent limitation to knowledge towards reconstructing the seismic cycle. For example, the occurrence of the 2021 Alaska earthquake Mw 8.2 within the rupture zone of the Mw 8.2 1938 Alaska earthquake, and 2021 Haiti earthquake Mw 7.2 within the same fault zone of the 2010 earthquake Mw 7.0 (which claimed 300,000 lives), reflects how much the characterization of the seismic cycle and earthquakes’ recurrence is critical for cities and regions which are under the constant seismic threat.
Modern techniques such as Remote Sensing, Geodesy, Geomorphology, Paleoseismology, and Geochronology play a vital role in constraining part of or full seismic cycles, with increased accuracy and temporal coverage of the long-term deformation. To fully understand these observations there is a need for a better understanding and integration of such techniques to be applied across different fault systems, globally.
The goal of this session is to bring together innovative approaches and techniques, to take a comprehensive look at the earthquake cycle for plate boundary fault systems to fault systems sitting far away from the plate boundary.
A well-designed experiment is a crucial methodology in Soil Science, Geomorphology and Hydrology.
Depending on the specific research topic, a great variety of tempo-spatial scales is addressed.
From raindrop impact and single particle detachment to the shaping of landscapes: experiments are designed and conducted to illustrate problems, clarify research questions, develop and test hypotheses, generate data and deepen process understanding.
Every step involved in design, construction, conduction, processing and interpretation of experiments and experimental data might be a challenge on itself, and discussions within the community can be a substantial and fruitful component for both, researchers and teachers.
This PICO session offers a forum for experimentalists, teachers, students and enthusiasts.
We invite you to present your work, your questions, your results and your method, to meet, to discuss, to exchange ideas and to consider old and new approaches.

The Quaternary Period (last 2.6 million years) is characterized by frequent and abrupt climate swings that were accompanied by rapid environmental change. Studying these changes requires accurate and precise dating methods that can be effectively applied to environmental archives. A range of different methods or a combination of various dating techniques can be used, depending on the archive, time range, and research question. Varve counting and dendrochronology allow for the construction of high-resolution chronologies, whereas radiometric methods (radiocarbon, cosmogenic in-situ, U-Th) and luminescence dating provide independent anchors for chronologies that span over longer timescales. We particularly welcome contributions that aim to (1) reduce, quantify and express dating uncertainties in any dating method, including high-resolution radiocarbon approaches; (2) use established geochronological methods to answer new questions; (3) use new methods to address longstanding issues, or; (4) combine different chronometric techniques for improved results, including the analysis of chronological datasets with novel methods, e.g. Bayesian age-depth modeling. Applications may aim to understand long-term landscape evolution, quantify rates of geomorphological processes, or provide chronologies for records of climate change.

Age models are applied in paleoclimatological, paleogeographic and geomorphologic studies to understand the timing of climatic and environmental change. Multiple independent geochronological dating methods are available to generate robust age models. For example, different kinds of radio isotopic dating, magneto-, bio-, cyclostratigraphy and sedimentological relationships along stratigraphic successions or in different landscape contexts. The integration of these different kinds of geochronological information often poses challenges.
Age-depth or chronological landscape models are the ultimate result of the integration of different geochronological techniques and range from linear interpolation to more complex Bayesian techniques. Invited speakers will share their experience in several modelling concepts and their application in a range of Quaternary paleoenvironmental and geomorphologic records. The Short Course will provide an overview of age models and the problems one encounters in climate science and geomorphology. Case studies and practical examples are given to present solutions for these challenges. It will prepare the participants from CL, GM and other divisions for independent application of suitable age-depth models to their climate or geomorphologic data.

The purpose of this session is to: (1) showcase the current state-of-the-art in global and continental scale natural hazard risk science, assessment, and application; (2) foster broader exchange of knowledge, datasets, methods, models, and good practice between scientists and practitioners working on different natural hazards and across disciplines globally; and (3) collaboratively identify future research avenues.
Reducing natural hazard risk is high on the global political agenda. For example, it is at the heart of the Sendai Framework for Disaster Risk Reduction and the Paris Agreement. In response, the last decade has seen an explosion in the number of scientific datasets, methods, and models for assessing risk at the global and continental scale. More and more, these datasets, methods and models are being applied together with stakeholders in the decision decision-making process.
We invite contributions related to all aspects of natural hazard risk assessment at the continental to global scale, including contributions focusing on single hazards, multiple hazards, or a combination or cascade of hazards. We also encourage contributions examining the use of scientific methods in practice, and the appropriate use of continental to global risk assessment data in efforts to reduce risks. Furthermore, we encourage contributions focusing on globally applicable methods, such as novel methods for using globally available datasets and models to force more local models or inform more local risk assessment.

The action of a fluid moving over a mobile surface often generates bedforms which in turn influence the flow and how particles are transported. On Earth, bedforms are found in many environments: deserts, rivers, estuaries, continental shelves, deep seas, volcanic regions and glacial environments. Bedforms have also been observed in extra-terrestrial environments, such as on Mars and Venus.
Understanding the links between flow, particle transport, and bedform morphodynamics and stratigraphy is of interest for a wide range of applied and fundamental research. For example, this knowledge is used to manage contemporary environments, such as rivers and coastal seas. Recently, the societal relevance of bedform research has been highlighted, as bedforms are shown to interact with offshore structures. Furthermore, bedform morphology and sedimentology can provide insights into fluid movement across modern and ancient, otherwise unknown, landscapes.
This session aims to highlight many aspects of the complex interaction between flow, sediment transport, stratigraphy and bedforms in terrestrial and planetary environments. The session welcomes contributions from theoretical, field, laboratory and numerical approaches related to bedforms found in aeolian, shallow and deep waters, glacial and planetary environments. The session intends to advance our knowledge of how to decipher information contained in terrestrial and extra-terrestrial bedforms and help foster fruitful discussions on understanding bedform morphodynamics and stratigraphy.

Sedimentary processes in aquatic environments, including erosion, transport, and deposition of sediment by hydrodynamic mechanisms, are key features for various research disciplines, e.g., geomorphology and paleoclimatology or hydraulics, river engineering and water resources management and hydrology. Accurate quantification of erosion, transport, and deposition rates, conditioning river channel morphology, and bed composition, is fundamental for adequate development of conceptual sediment budget models and for the calibration and validation of the numerical tools.
The main goal of this session is to bring together the community of scientists, scholars, and engineers, investigating, teaching, and applying novel measurement techniques and monitoring concepts, which are crucial in determining sedimentary and hydro-morphological processes in rivers, lakes, and reservoirs, estuaries as well as in coastal and maritime environments. It focuses on the quantification of bedload and suspended load, bedforms migration, channel horizontal migration, bed armoring and colmation, but also the transport mode, flocculation, settling, and re-suspension of the sediment particles.
Contributions are welcome with a particular focus on single and combined measurement techniques, post-processing methods as well as on innovative and advanced monitoring concepts for field and laboratory applications. We welcome contributions containing recent results in a temporal and spatial scale on sediment budgets as well as on sedimentary and morphodynamic processes in open water environments.
Contributions may refer but are not restricted to:
• Measurements of suspended sediment and/or bedload transport in open water environments, e.g., with classical or novel methods;
• Determination of sediment characteristics, e.g., with mechanical bed material samplers or freeze core technique;
• Innovative measurement approach or techniques aimed for validation and calibration of numerical models;
• Measurements of critical bed shear stress of cohesive sediments, e.g., with benthic flumes or miscellaneous devices;
• Monitoring of morphological changes like lake and reservoir sedimentation, bank erosion or bed armoring, meandering
migration, river bends evolution;
• Measuring networks / multiple point datasets;
• Large- or small-scale monitoring concepts including case studies;
• In-situ or laboratory calibration of measurement data using classical or novel (e.g., machine learning) approaches;

Complex hydro-morphological processes, such as sediment erosion, transport, deposition, or fan development, affect open water environments, including rivers, estuaries as well as lakes and reservoirs. Consequently, many research tasks as well as practical applications rely on the correct prediction of these processes. During the last decades, numerical models have become a powerful tool in the research fields of hydraulic engineering and geosciences to simulate these hydro-morphological processes. With improved algorithms as well as an ever-growing computational power, it became feasible to simulate the interaction of water, sediments, and air with high resolution in space and time. In addition, with an increasing quantity and quality of validation data from laboratory experiments and field studies, numerical models are continuously enhanced so that many good examples of sediment transport modelling offer new insights in multiphase processes, e.g., dune development, river bed armouring or density-driven transport. Hence, new generations of numerical techniques open the possibility to explore numerous outstanding research questions related to hydro-morphologic processes. Artificial Intelligence procedures offer an additional alternative to hydro-morphological studies, e.g., determining particle size or floodplain vegetation cover.
The main goal of this session is to bring together scientists and engineers, who develop, improve, and apply numerical models of multiphase flows for sediment transport in open water environments. We invite contributions that deal with numerical modelling from small-scale, such as bed structure development, to large-scale interactions, such as long-term development of hydro-morphological processes in rivers, lakes, reservoirs, and estuaries.
Contributions may refer, but are not restricted, to:
• Entrainment processes of sediments (from cohesive sediments to armoured river beds)
• Bed load and suspended sediment transport processes (including flocculation processes)
• Simulation of sediment management including planning, operation and maintenance of hydro power plants
• Design and evaluation of restoration measures to revitalize rivers
• Navigation issues, such as sediment replenishment, dredging and erosion induced by ship generated waves
• Flood related issues of long term effects of morphological bed changes on flood security
• Eco-hydraulics such as flow – sediment – vegetation interaction
• Density driven transport

The production, transport, and deposition of sediment and the evolution of hillslopes and river networks govern the fluxes and distribution of solid mass on the surface of the Earth. The frequency, magnitude, and physical and chemical properties of these fluxes are initially controlled by external forcing (climate and tectonics) before being modulated by the complex interplay of surface processes. Understanding the interplay of these processes and how they are affected by external forcing is vital to understanding how sediment fluxes and topography have changed through time.
A growing body of studies continues to develop a process-based understanding of the coupling between climate, tectonics, and the evolution of catchments and the production and transport of solids within them. However, many challenges remain including; (1) fully quantifying the rates and patterns of erosion, sediment transport, and landscape evolution, (2) assessing the importance of large and infrequent events in controlling erosion and sediment transport, (3) bridging the gap between short- and long-term or small- and large-scale records of erosion, deposition, and landscape evolution, and (4) determining the impact of lithology on these records.
In this session we welcome field-based, experimental, and modelling studies, that (1) constrain mechanisms, rates, and scales of erosion, transport, and deposition processes, (2) analyse the influence of internal and external forcing on these processes or resulting landscape evolution, and/or (3) investigate the propagation of geochemical or physical signals across the earth surface (such as changes in river network morphology, sedimentary fluxes, grain size distributions, or cosmogenic nuclide concentrations).Contributions across all temporal and spatial scales are welcome.
Hydro-geomorphic connectivity has emerged as a significant conceptual framework for understanding the transfer of surface water and materials (e.g. sediment, plant propagules, and nutrients) through landscapes. The concept of connectivity has had particular success in the fields of catchment hydrology, fluvial geomorphology and soil erosion, but has also been employed in, for example, studies of hydrochory. Connectivity as applied in various disciplines can be a transformative concept in understanding complex systems, allowing analyses of how such systems behave in terms of scaling, catastrophic/phase transitions, critical nodes, emergence and self-organization, e.g. by applying network-based analyses and modelling. Recent research also highlights the widespread nature of disconnectivity in river and catchment systems, caused by natural and anthropogenic structures including dams, log jams, or agricultural terraces. These and other forms of disconnectivity can have large spatial and temporal implications on ecological, geomorphic, hydrological and biogeochemical processes through buffering water and material fluxes. We aim to create a diverse interdisciplinary session that reflects a broad range of research seeking to illustrate the role of (dis-)connectivity in river and catchment systems. We hope to use the session to develop a discussion of the dual roles of connectivity and disconnectivity to generate a basis for an integrated framework to be applied across different fields of geosciences and for managing river and catchment systems.

Soil erosion is a major global soil degradation threat to land, freshwater and oceans. Scientific understanding of all erosional physical processes controlling soil detachment, transportation, and deposition is vital when developing methods and conservation alternatives to minimize the impacts associated with soil degradation and support decision making.
This session will discuss the latest developments in soil erosion and closely associated land degradation processes in agriculture, forest and rangelands. Providing space for presenting and discussing:
• measurements - from rill to gully erosion, by means of field essays or laboratory experiments;
• monitoring - short to long-term assessments, by mean of local assessments or remote sensing techniques;
• modelling approaches – from plot to global scale, addressing current and future land and climate change demands;
• mitigation and restoration – to address on-site and off-site impacts on soils and water.
Our main objective is to scientifically discuss soil erosion processes and impacts but also to explore strategies that may help land stakeholders (farmers, land managers or policy makers), and support the ongoing initiatives aiming for land degradation neutrality by 2030 and the upcoming UN Decade on Ecosystem Restoration (2021-2030).
Soil is the largest carbon (C) reservoir in terrestrial ecosystems with twice the amount of atmospheric C and three times the amount in terrestrial vegetation. Carbon related ecosystem services include retention of water and nutrients, promoting soil fertility and productivity and soil resistance to erosion. In addition, changes in the soil C can have strong implications for greenhouse gas emissions from soil with implications in environmental health.
Drivers controlling C pools and its dynamics are multiple (e.g. land use/vegetation cover, climate, texture and bedrock, topography, soil microbial community, soil erosion rates, soil and other environment management practices, etc. ) and mutually interacting at various time and spatial scales. At the one time, rate of soil C loss can be high due to both climatic constrains or unsuitable management. Thus, investigating C dynamics include the adaptation of the management factors to the actual climate, the climate change and climatic extreme events to provide a better understanding of carbon stabilization processes and thus support decision making in soil management and climate adaptation strategies.
The present session highlights the importance of soil C changes, and the interaction among the mechanisms affecting C concentration and stocks in soil, including soil management. Discussion about proxies of measurement and modelling organic and inorganic C flows, concentration and stocks, with special emphasis to cropping systems and natural/semi-natural areas, is encouraged. These proxies should be approached at varying the availability of soil and environment information, including, e.g., soil texture, rainfall, temperature, bulk density, land use and land management, or proximal and remote sensing properties. Studies presented in this session can aim to a wealth of aims, including soil fertility, provision of ecosystem services, and their changes, and the implication for economy, policy, and decision making.
Types of contribution appreciated include, but are not limited to, definitive and intermediate results; project outcomes; proposal of methods or sampling and modelling strategies, and the assessment of their effectiveness; projection of previous results at the light of climate change and climatic extremes; literature surveys, reviews, and meta-analysis. These works will be evaluated at the light of the organisation of a special issue in an impacted journal
Soils and palaeosols develop under the influence of various environmental factors that produce specific soil features, thus keeping a memory of both current and past environments. They are valuable archives of human activities that shaped environments and affected soil formation over the Holocene period. They can be studied to reconstruct environmental factors that were present during the time of their formation, and to disentangle the relative influences of different environmental conditions, both local and regional, on soil formation. Despite the increasing consideration of palaeosols in sedimentary successions, studies linking pedogenesis and sedimentary processes are still underrepresented. Anthropogenic soils in archaeological settings provide valuable archives for geoarchaeological studies, with their stratigraphy and properties reflecting settlement life cycles (occupation, abandonment, and reoccupation) and land-use history. Land-use legacy soils also have enormous potential for process-related research such as studying the long-term effects on the organic and inorganic carbon budget, physical compaction, aggregation, formation of anthropogenic pedofeatures and more.
This session is open for all contributions focused on the study of palaeosols, anthropogenic soils, and anthropogenically-affected soils, in particular on:
- The use of palaeosols and land-use legacy soils as records of present and former environments, both local and regional;
- Palaeosols and anthropogenically-affected soils and their relationships with sedimentary processes;
- Anthropogenic soils and palaeosols in archaeological contexts;
- The methodological progress in the study of soil records (for example, advances in biochemical, geochemical, and micromorphological (sub-)microscopic techniques in palaeopedology, in the interpretation of palaeoenvironmental data such as biomarker and isotope data, in remote sensing or modelling methods used to map and analyze spatial patterns of palaeosol and land use legacy soil distribution);
- Predictions of future soil changes as a result of changes in environmental conditions and/or land-use, based on observed past soil responses to environmental changes.

Dissolution, precipitation, and chemical reactions between infiltrating fluid and rock matrix alter the composition and structure of the rock, either creating or destroying flow paths. Strong, nonlinear couplings between the chemical reactions at mineral surfaces and fluid motion in the pores often leads to the formation of intricate patterns: networks of caves and sinkholes in karst area, wormholes induced by the acidization of petroleum wells, porous channels created during the ascent of magma through peridotite rocks. Dissolution and precipitation processes are also relevant in many industrial applications: dissolution of carbonate rocks by CO2-saturated water can reduce the efficiency of CO2 sequestration, mineral scaling reduces the effectiveness of heat extraction from thermal reservoirs, acid rain degrades carbonate-stone monuments and building materials.
With the advent of modern experimental techniques, these processes can now be studied at the microscale, with direct visualization of the evolving pore geometry. On the other hand, the increase of computational power and algorithmic improvements now make it possible to simulate laboratory-scale flows while still resolving the flow and transport processes at the pore-scale.
We invite contributions that seek a deeper understanding of reactive flow processes through interdisciplinary work combining experiments or field observations with theoretical or computational modeling. We seek submissions covering a wide range of spatial and temporal scales: from table-top experiments and pore-scale numerical models to the hydrological and geomorphological modelling at the field scale. We also invite contributions from related fields, including the processes involving coupling of the flow with phase transitions (evaporation, sublimation, melting and solidification).

Climate-induced geohazards are known to increase with climate change causing more intense rainfall and more frequent extreme weather events. Use of vegetation on potentially unstable slopes and along stream banks is an example of Nature-Based Solutions (NBS) that can mitigate climate induced geohazards due their role at the soil-atmosphere interface. Vegetating slopes or stream banks are also key for ecological restoration and rewilding, providing several additional co-benefits. However, researchers in different fields of science or practitioners do not easily communicate, even though they are addressing aspects of the same problem.
Interdisciplinary research and bilateral communication are needed to document the effects of vegetation in hazard-prone areas in a measurable and applicable manner. These NBS must have an ecological approach, where in the long-term perspective, a multiple approach for biodiversity and ecosystem services will give mutual synergies.
This session aims to stimulate interdisciplinary communication, knowledge exchange and dissemination on plant-soil-atmosphere interaction, with focus on vegetation mitigating climate-induced geohazards, particularly shallow landslides and erosion.
Contributions documenting how vegetation and roots can be beneficial also in land use planning, restoration ecology, climate change adaptation are welcome within the fields of geotechnical engineering, plant ecology, biodiversity, alpine timberline, hydrogeology and agronomy.
Interaction between research and industry, with involvement of NBS entrepreneurs, are particularly welcome.
Topics of interested are listed, including, but not limited to:
• Experimental, either laboratory or field, or numerical investigation of plant-soil-atmosphere interaction and its relation to slope or bank stability
• How to implement morpho-mechanical parameters of plants in engineering design?
• Measuring and quantifying the effects of vegetation as NBS to mitigate climate-induced geohazards
• Tools, approaches, and frameworks demonstrating how vegetation can be used to mitigate climate-induced geohazards, while providing additional co-benefits
• Investigation on upscaling potential from laboratory to slope and catchment scale
• Case studies of restoration or stabilisation works, especially on design principles and performance assessment
• Ensuring interdisciplinary interaction and mutual synergies for studies containing vegetation as NBS among different disciplines

Rockfalls, rockslides and rock avalanches are among the primary hazards and drivers of landscape evolution in steep terrain. The physics of rock slope degradation and dynamics of failure and transport mechanisms define the hazards and possible mitigation strategies and enable retrodictions and predictions of events and controls.
This session aims to bring together state-of-the-art methods for predicting, assessing, quantifying, and protecting against rock slope hazards across spatial and temporal scales. We seek innovative contributions from investigators dealing with all stages of rock slope hazards, from weathering and/or damage accumulation, through detachment, transport and deposition, and finally to the development of protection and mitigation measures. In particular, we seek studies presenting new theoretical, numerical or probabilistic modelling approaches, novel data sets derived from laboratory, in situ, or remote sensing applications, and state-of-the-art approaches to social, structural, or natural protection measures. We especially encourage contributions from geomechanics/rock physics, geodynamics, geomorphology and tectonics to better understand how rockfall, rockslides and rock avalanches act across scales.

The global increase in damaging landslide events has attracted the attention of governments, practitioners, and scientists to develop functional, reliable and (when possible) low cost monitoring strategies. Numerous case studies have demonstrated how a well-planned monitoring system of landslides is of fundamental importance for long and short-term risk reduction.
Today, the temporal evolution of a landslide is addressed in several ways, encompassing classical and more complex in situ measurements or remotely sensed data acquired from satellite and aerial platforms. All these techniques are adopted for the same final scope: measure landslide motion over time, trying to forecast future evolution or minimally reconstruct its recent past. Real time, near-real time and deferred time strategies can be profitably used for landslide monitoring, depending on the type of phenomenon, the selected monitoring tool, and the acceptable level of risk.
This session follows the general objectives of the International Consortium on Landslides, namely: (i) promote landslide research for the benefit of society, (ii) integrate geosciences and technology within the cultural and social contexts to evaluate landslide risk, and (iii) combine and coordinate international expertise.
Considering these key conceptual drivers, this session aims to present successful monitoring experiences worldwide based on both in situ and/or remotely sensed data. The integration and synergic use of different techniques is welcomed, as well as newly developed tools or data analysis approaches, including big data management strategies. Specifically, a thematic focus will be on applications combining satellite, aerial or ground remote sensing with geophysical data such as electrical, seismic or electromagnetic surveys. The session is expected also to present case studies in which multi-temporal and multi-platform monitoring data are exploited for risk management and Civil Protection aims with positive effects in both social and economic terms.
Debris flows are among the most dangerous natural hazards that threaten people and infrastructures in both mountainous and volcanic areas. The study of the initiation and dynamics of debris flows, along with the characterization of the associated erosion/deposition processes, is of paramount importance for hazard assessment, land-use planning and design of mitigation measures, including early warning systems. In addition, the impacts of climate change on debris-flow activity must be considered and carefully analysed, as the number of mountain areas prone to these events may increase in future.
A growing number of scientists with diverse backgrounds are studying debris flows and lahars. The difficulties in measuring parameters related to their initiation and propagation have progressively prompted research into a wide variety of laboratory experiments and monitoring studies. However, there is a need of improving the quality of instrumental observations that would provide knowledge for more accurate hazards maps and modeling. Nowadays, the combination of distributed sensor networks and remote sensing techniques represents a unique opportunity to gather direct observations of debris flows to better constrain their physical properties.
Scientists working in the field of debris flows are invited to present their recent advancements. In addition, contributions from practitioners and decision makers are also welcome. Topics of the session include: field studies and documentation, mechanics of debris-flow initiation and propagation, laboratory experiments, modeling, monitoring, impacts of climate change on debris-flow activity, hazard and risk assessment and mapping, early warning, and alarm systems.
Landslides are ubiquitous geomorphological phenomena with potentially catastrophic consequences. In several countries, landslide mortality can be higher than that of any other natural hazard. Predicting landslides is a difficult task that is of both scientific interest and societal relevance that may help save lives and protect individual properties and collective resources. The session focuses on innovative methods and techniques to predict landslide occurrence, including the location, time, size, destructiveness of individual and multiple slope failures. All landslide types are considered, from fast rockfalls to rapid debris flows, from slow slides to very rapid rock avalanches. All geographical scales are considered, from the local to the global scale. Of interest are contributions investigating theoretical aspects of natural hazard prediction, with emphasis on landslide forecasting, including conceptual, mathematical, physical, statistical, numerical and computational problems, and applied contributions demonstrating, with examples, the possibility or the lack of a possibility to predict individual or multiple landslides, or specific landslide characteristics. Of particular interest are contributions aimed at: the evaluation of the quality of landslide forecasts; the comparison of the performance of different forecasting models; the use of landslide forecasts in operational systems; and investigations of the potential for the exploitation of new or emerging technologies e.g., monitoring, computational, Earth observation technologies, in order to improve our ability to predict landslides. We anticipate that the most relevant contributions will be collected in the special issue of an international journal.
Obtaining quantitative information on the spatial pattern of soil redistribution during storms and on the spatial sources supplying sediment to rivers is required to improve our understanding of the processes controlling these transfers and to design effective control measures. It is also crucial to quantify the transfer or the residence times of material transiting rivers along the sediment cascade, and to reconstruct the potential changes in sources that may have occurred at various temporal scales. During the last few decades, several sediment tracing or fingerprinting techniques have contributed to provide this information, in association with other methods (including soil erosion modelling and sediment budgeting). However, their widespread application is limited by several challenges that the community should address as priorities.
We invite specific contributions to this session that address any aspects of the following:
• Developments of innovative field measurement and sediment sampling techniques;
• Soil and sediment tracing techniques for quantifying soil erosion and redistribution;
• Sediment source tracing or fingerprinting studies, using conventional (e.g. elemental/isotopic geochemistry, fallout radionuclides, organic matter) or alternative (e.g. colour, infrared, particle morphometry) approaches;
• Investigations of the current limitations associated with sediment tracing studies (e.g. tracer conservativeness, uncertainty analysis, particle size and organic matter corrections);
• Applications of radioisotope tracers to quantify sediment transit times over a broad range of timescales (from the flood to the century);
• The association of conventional techniques with remote sensing and emerging technologies (e.g. LiDAR);
• Integrated approaches to developing catchment sediment budgets: linking different measurement techniques and/or models to understand sediment delivery processes.
Denudational hillslope and fluvial processes, associated source-to-sink fluxes and sedimentary budgets are controlled by a range of environmental drivers and anthropogenic activities, exacerbated by the consequences of climate change. A better understanding of the drivers, mechanisms and rates of contemporary denudational hillslope and fluvial processes as well as of the sediment and hydrological connectivity across a range of different spatio-temporal scales and climatic zones has significant societal implications for water quality, hydraulic infrastructures, aquatic ecosystems, public safety, and biogeochemical cycles.
The session aims to bring together interdisciplinary researchers working across field, experimental, numerical modelling, remote sensing, and dating approaches who are advancing methods and providing new insights into: (i) slope mass movements (e.g., landslides, rockfalls, and debris flows) and related hazard cascades in mountainous environments; (ii) water, sediment and solute source-to-sink processes in different climate zones (e.g., cold climate, temperate, arid and tropical regions) from small headwaters to large river systems at event, seasonal, and multi-decadal scales; and (iii) the anthropogenic impacts and societal implications of changing hillslope and fluvial processes and possible solutions for future sustainable management.
We encourage the participation of early-career researchers and PhD students working in the fields of geomorphology, hydrology, hazard, glaciers, permafrost, and aquatic ecosystems, as we aim to expand and integrate the network of researchers addressing this complex subject across scientific disciplines.

Land cover dynamics are driving forces for geomorphic processes in mountain landscape inducing beneficial and adverse effects on landscape. Consequently, detecting and monitoring land cover changes are of fundamental relevance in a wide spectrum of useful applications for adjusting soil protection and land management policies. Moreover, they are necessary to identify hillslope denudation, to quantify the soil loss, and to assess changing environmental conditions (vegetation communities and soil properties). Land cover data can be acquired at local, regional and/or global scales using traditional and/or innovative technologies (from field measurements to remote sensing) with different accuracy. Using such information, most investigations have been focusing on analysing, modelling and predicting geomorphic and landform-shaping processes that have a strong impact on both natural ecosystems and cultivated lands in terms of economic, social and environmental implications. In particular, the alterations of soil properties and vegetation cover in terms of soil aggregation, soil detachment, soil reinforcement and/or soil hydrological processes, are often causes of more complex and extremely difficult to predict landscape processes.
Thus, this session aims to group together the most recent scientific research and activities, especially those paying heed to transient or long-term slope failure mechanism as well as surface/subsurface water flow and soil erosion processes. Research abstracts are invited to address:
1. observation of land cover types, land cover changes (urbanization, road building, forest destruction, etc.), and occurrences of geomorphic processes (erosion, landslides, rockfalls) using a wide spectrum of technologies (field instruments, unmanned aerial vehicles and satellite images);
2. investigation on relationship between land cover change and surface processes at different scales (from hillslope to regional scale);
3. assessment of soil instabilities (erosion, landslides, rockfalls) through innovative modelling approaches (statistical, physical-based and numerical);
4. development of guidelines and regulations for practitioners, technicians, policy and decision makers.
We highly welcome pioneering research from all fields, especially from geomorphology, agricultural science, soil science, geotechnics and environmental engineering. Early career scientists are encouraged to contribute to the session with original and advanced studies.
Biogeomorphology addresses the two-way interaction between abiotic and biotic elements that shape landscapes at various spatio-temporal scales. Yet, developing theory, methods and quantifying processes across the abiotic/biotic interface remains challenging. This is partly due to the interdisciplinarity of biogeomorphology, integrating concepts from biology, climatology, engineering, Earth surface science and geology (amongst other disciplines). Although more and more biogeomorphic feedbacks are being investigated, understood, and applied in practice, many of these remain poorly studied and understood. However, a better understanding of abiotic-biotic interaction across scales is urgently needed for a more holistic understanding of the Earth surface as well as ecological dynamics for sustainable management, and climate change mitigation and adaptation.
This session aims to bring together geoscientists, soil scientists and biologists working at different spatial and temporal scales on how climate, tectonics, soils, flora and fauna affect landscape development, erosion control and thus form the Earth’s surface. Thus, we provide a discussion platform for all aspects of biogeomorphology, including fundamental science and applied studies. Topics may include, but are not limited to, biogeomorphic processes, rates and feedbacks for biotic and/or abiotic processes, climate-tectonics-earth surface dynamics, and biogeomorphology as a tool to sustainably manage natural systems and hazards. We encourage everyone interested in biogeomorphology to contribute to the session to further strengthen the community and stimulate discussion and collaboration across scales.

Geodiversity is a recent relevant topic among Geosciences, and characterizes drainage basins, which record information from a variety of components of the natural environment, relevant for the scientific assessment of both long-term evolutionary processes and interpretation of recent responses to climate change, as well as for the Nature-Human interactions. The establishment of a conceptual/methodological framework for multifactor/multidimensional approaches to Geodiversity of drainage basins is of relevant value for the enhancement of the related geosystem services.
From slope micro-catchments to large drainage systems, river basins are geosystems characterized by a high degree of individuality. Geodiversity assessment at various scales offers advanced knowledge on river catchment functioning by means of many conditioning factors, such as: geology, lithology, tectonics, geomorphology, energy and matter cycle, connectivity between slope and fluvial subsystems, soil, climate, land cover and land use etc. The variety of such environmental features controls the functional connectivity of river basins.
Since each catchment represents a different object, the assessment of geodiversity within river basins (i.e. intrinsic) appears as a complex analytical process of each element; at the same time, it drives the relationships between different basins (i.e. extrinsic geodiversity).
The key issue is the selection of criteria for assessing geodiversity considering the spatial, thematic and temporal resolutions. Another open problem is the assessment of services offered by geodiversity of drainage basins (i.e. geosystem services), particularly those in highly dynamic conditions due to present day climate change.
In this session, we aim to receive contributions on two closely-related concepts in a contemporary challenge for geoscientists. How can geodiversity and the related variable features limit the geosystem services? This question arises in present-day communities as the dilemma of using and exploiting river basin resources while preserving them for future generations. Different morphoclimatic conditions make great landscape, and in the specific drainage basins complexities and different possibilities of providing geosystem services emerges. These issues become particularly powerful in the era of the United Nations Sustainable Development Goals.

The North-Atlantic-Arctic realm hosts vast extended continental shelves bordering old land masses, two Large Igneous Provinces (LIPs), one of which is the largest known sub-marine LIP (Alpha-Mendeleev Ridge) and a complex ocean spreading systems, including the slowest mid-ocean spreading ridge (Gakkel Ridge) and several extinct ocean basins.
Over recent decades, increasing scientific interest has led to the acquisition of vast quantities of geological and geophysical data across the North Atlantic-Arctic realm, yet our understanding of the region has become, if anything, even more controversial than it was before. The geodynamic and geomorphological processes acting here (and globally) are key to the understanding of the structure, geodynamic and paleolandscape evolution, hazards and resources in the region.
This session provides a forum for discussions and reviews of a variety of problems linked to the North Atlanitc-Arctic geodynamics such as plate tectonic, geodynamic, compositional, thermal, structural and landscape models, configuration of sedimentary basin and to propose additional experiments that can test these models. We welcome contributions from all relevant disciplines, including, but not limited to, plate tectonics, geophysics, geodynamic modelling, igneous, metamorphic and structural geology, palaeomagnetism, sedimentology, geomorphology, geochronology, thermochronology, geochemistry and petrology.

Wildfires are a worldwide phenomenon with many environmental, social, and economic implications, which are expected to escalate as a consequence of climate change and land abandonment, management, and planning, further promoting land degradation and decreasing ecosystem services supply.
The current situation demands from the scientific community the study of wildfire effects on the ecosystems and the development of integrated tools for pre- and post-fire land management practices that reduce the vulnerability to wildfires and their impacts. However, this research urges the attention not only from researchers, but also from stakeholders and policy-makers all over the world, since basic resources such as raw materials, water, and soils as well as habitats are at stake.
This session aims at gathering researchers on the effects of wildfires on ecosystems, from wildfire prevention to post-fire mitigation. We kindly invite laboratory, field, and/or modelling studies involving the following topics:
i. prescribed and/or experimental fires;
ii. fire severity and burn severity;
iii. fire effects on vegetation, soil and water;

The management of soil and water resources for sustainable development is critical for human well-being. Over the recent decades, many studies have demonstrated the role of water and sediment connectivity processes in relation to watershed management. Habitat and species protection, improved flood resistance and resilience, and ecosystems management are all vital to maintaining the health of ecosystems. Especially when external factors influence watershed processes and characteristics to maintain optimal connectivity or disconnectivity in diverse ecological niches (hydrology, ecology, geomorphology) is the goal of watershed management. Given the high complexity of hydro-geomorphic systems and the different mechanisms that might influence the efficiency of water and sediment flowing through a watershed, understanding the hydrological and sediment connectivity is critical. Meanwhile, analyzing changes in connectivity over time helps to understand the effects of natural and man-made disturbances on water-sediment flux and related processes. However, we still have very little understanding about connectivity and link all the processes involved. Models are valid tools in this task, but they need to be improved. In this session, we welcome studies focused on connectivity with watershed management. Any contributions related to new methods, approaches to the understanding of connectivity are welcomed. Field monitoring, laboratory simulations, development and application of geomorphometric indices and models are included. This session emphasizes the importance of connectivity in appropriately managing sediment and water-related concerns, and aims at providing important information on when, where, and how to managers in order to control hydrological and geomorphic processes and ultimately achieve sustainable watershed management.
Fluvial systems cover much of the Earth’s surface; they convey water, sediments, and essential nutrients from the uplands to the sea, intermittently transferring these materials from the river channel to the adjacent floodplain. The routing of sediment and water through the channel network and into the fluvial-tidal transition zone initiates complex process-form interactions as the river bed and banks adjust to changes in flow conditions. Despite their ubiquity, little is known about the landform-driven morphodynamic interactions taking place within the channel that ultimately determine patterns of sedimentation and changes of channel form. Furthermore, an understanding of how these process-form interactions scale with the size of the fluvial system is also currently lacking. Recent technological and methodological advances now afford us the opportunity to study and to quantify these process-form interactions in detail across a range of spatial and temporal scales.
At the coast, complex physical and ecological interactions coupled with anthropogenic and climate driven changes in sediment supply and hydrological behaviour control net changes in the filling of accommodation space. Sustainably managing these coastal regions requires a holistic understanding of how these processes interact over different timescales.
This session aims to bring together interdisciplinary researchers working across field, experimental, and numerical modelling approaches who are advancing methods and providing new insights into: (i) sediment transport and morphodynamic functioning of fluvial and coastal systems, (ii) evaluating morphological change at variable spatial and temporal scales, such as at event vs. seasonal scales, (iii) investigating the sedimentology of these river systems, and iv) understanding how anthropogenic and climate changes may influence the evolution of these systems. We particularly welcome applications which investigate the morphodynamic response of fluvial systems in all types and sizes and we would specifically like to encourage submissions from early career researchers and students.

The United Nations has designated the 2020s as the decade of ecosystem restoration; and restoration of streams, rivers and their catchments is particularly important to restore ecosystems and halt biodiversity loss, in addition to achieving several sustainable development goals. Within Europe, river restoration is used to meet the EU Water Framework Directive objectives, and EU LIFE projects provide millions of euro per year to physical restoration. Furthermore, restoration of rivers and their catchments will prove both more important in the coming decades in order to mitigate and adapt to the effects of climate change and more challenging when restoring a moving target with altered flow, sediment, and ice regimes and habitat conditions. Restoration and management of rivers and their catchments will require a holistic view of multiple facets of river systems and will need to be process-based, including geomorphic, hydrological and ecological processes, incorporating an understanding of how these evolve and interact following restoration interventions. In addition, large wood (LW) is a key component of fluvial ecosystems and affects both flow and sediment transport processes. LW jams (i.e., logjams) can be used as a tool for river restoration increasing flow and bed heterogeneity. However, the transportation of LW may significantly increase during floods and LW jams can form at river infrastructure, creating an additional flood risk, which needs to be accounted for in management strategies of rivers. An interdisciplinary effort is required to improve our understanding of the complex interactions of wood with flow and sediment in fluvial ecosystems.
In this session we wish to highlight a broad range of research on methods, success/failure, and follow-up of river and catchment restoration and management. We are particularly interested in studies related to restoration with a changing baseline of climate conditions as well as aspects associated with LW; however, there are also many basic questions on how to manage and restore rivers that also need to be addressed, including time-to-recovery, resilience, relationships between different river facets, the impact of different spatial scales of restoration, etc. We hope this session will spark discussion among an interdisciplinary group of researchers of how to take into account a changing climatic baseline in future river restoration and evaluation of restoration success.
Water is our planet’s most vital resource, and the primary agent in some of the biggest hazards facing society and nature. Recent extreme heat and flood events are clear demonstrations of how our planet’s climate is changing, underlining the significance of water both as a threat and as an increasingly volatile resource.
The accurate and timely measurement of streamflow is therefore more critical than ever to enable the management of water for ecology, for people and industry, for flood risk management and for understanding changes to the hydrological regime. Despite this, effective monitoring networks remain scarce, under-resourced, and often under threat on a global scale. Even where they exist, observational networks are increasingly inadequate when faced with extreme conditions, and lack the precision and spatial coverage to fully represent crucial aspects of the hydrological cycle.
This session aims to tackle this problem by inviting presentations that demonstrate new and improved methods and approaches to streamflow monitoring, including:
1) Innovative methodologies for measuring/modelling/estimating river stream flows;
2) Real-time acquisition of hydrological variables;
3) Remote sensing and earth observation techniques for hydrological & morphological monitoring;
4) Measurement in extreme conditions associated with the changing climate;
5) Measurement of sudden-onset extreme flows associated with catastrophic events;
6) Strategies to quantify and describe hydro-morphological evolution of rivers;
7) New methods to cope with data-scarce environments;
8) Inter-comparison of innovative & classical models and approaches;
9) Evolution and refinement of existing methods;
10) Guidelines and standards for hydro-morphological streamflow monitoring;
11) Quantification of uncertainties;
12) Development of expert networks to advance methods.
Contributions are welcome with an emphasis on innovation, efficiency, operator safety, and meeting the growing challenges associated with the changing climate, and with natural and anthropogenically driven disasters such as dam failures and flash floods.
Additionally, presentations will be welcomed which explore options for greater collaboration in advancing riverflow methods and which link innovative research to operational monitoring.

Coastal wetland ecosystems, such as salt marshes, mangroves, seagrass beds and tidal flats, are under increasing pressure from natural and anthropogenic processes shifting climatic conditions, and are declining in area and habitat quality globally. These environments provide numerous ecosystem services, including flood risk mediation, biodiversity provision and climate change mitigation through carbon storage. Hence, the need to get a deeper understanding of processes and interactions in these environments, and how these may be altered by climate change has never been greater. This is the case for ‘managed’, restored wetlands and natural systems alike.
This session will bring together studies of coastal wetland ecosystems across climates and geomorphic settings, to enhance the understanding of ecosystem service provisioning, interactions between hydrodynamics, sediment and ecology, and identify best future management practices. Studies of all processes occurring within coastal wetlands are invited. This includes, but is not exclusive to, sediment dynamics, hydrology, hydrodynamics, biogeochemistry, morphological characterisation, geotechnical analysis, bio-morphodynamics, ecological change and evolution, impact of climate change, sea level rise, anthropogenic and management implications. Experiences from wetlands restoration projects are welcomed to increase knowledge on how to achieve wetlands long-term resilience. Multidisciplinary approaches across spatial and temporal scales are encouraged, especially in relation to global climate change. This session aims to enhance our understanding of basic processes governing coastal wetland dynamics and to propose sustainable management solutions for contemporary environmental pressures.
Low-lying coastal areas can be an early casualty to sea-level rise, especially where enhanced by land subsidence. An ever increasing number of studies indicates that land subsidence due to natural and anthropogenic causes has induced damage to wetland ecosystems in many countries worldwide, and has increased flooding hazard and risk. Coastal subsidence causes include excessive groundwater extraction from aquifers, peat oxidation due to surface water drainage through land reclamation, urbanization and agricultural use, as well as sediment starvation due to construction of dams and artificial levees. Contrary to the global processes behind sea-level rise, natural and anthropogenic coastal subsidence is primarily a local phenomenon, and its causes and severity may vary substantially from place to place.
The combination of geological and historical measurements with remote sensing data is required to understand all drivers of coastal vertical land motion and the contributions to past, present, and future subsidence.
Understanding coastal subsidence requires multidisciplinary expertise, models, and remote and in-situ observations from geology, geodesy, natural hazards, oceanography, hydrogeology, and geomechanics. In this session, we aim to bring together all the involved disciplines. We invite contributions on all aspects of coastal subsidence research and applications, including recent advances on: i) measurement through ground-based, aerial and satellite remote sensing techniques, ii) numerical models and future projections, iii) their applicability to distinguish between the different drivers contributing to land subsidence, and iv) quantification of coastal hazards associated with relative sea-level rise. In particular, efforts towards characterizing human intervention on coastal vertical land motion are welcomed.

Detailed seabed maps portraying the distribution of geomorphic features, substrates, and habitats are used for a wide range of scientific, maritime industry, and government applications. These maps provide essential information for ocean industry sectors and are used to guide local and regional conservation action. Fundamental to seabed mapping are acoustic remote sensing technologies, including single beam and multibeam echosounders and sidescan, interferometric, and synthetic-aperture sonars. These are deployed on a variety of crewed and robotic surface and underwater platforms. In shallow clear waters, optical sensors including LiDAR, multispectral, and hyperspectral cameras are also increasingly employed from aircraft, drones, and satellites to create maps of the seabed. Innovative data processing, image analysis, and statistical approaches for classification are advancing the field of seabed mapping. These methods are yielding increasingly comprehensive and detailed maps. We welcome submissions that provide insights into the use of advanced technologies, novel processing and analytical approaches, and current and emerging applications in the field of seabed mapping and classification – from shallow coastal waters to the deep seafloor.

Coastal zones worldwide face numerous pressures of anthropogenic impact, including urbanization, pollution, and resource extraction. Associated problems include coastal erosion, often aggravated by hard engineering responses, and pollution of waters and sediments affecting ecology and human health.
This session explores the interactions between natural geomorphic processes and human interventions in the coastal zone. Topics include work on predicting shoreline change and the effects of human activities on the coast, including coastal vulnerability to natural and human-related hazards, coastal and environmental sensitivity classifications and risk assessments, impacts on coastal dune fields, eco-restoration and re-building of coastal environments, Marine Spatial Planning, and Integrated Coastal Management.

Examining the morphodynamics of coasts from the nearshore through to inland dune systems, is a fundamental requirement in understanding their short- to long-term behaviour. Operating across large spatial and temporal scales, examination of their resulting landforms is both difficult and complex. Recent methodological advances, however, now enable traditionally isolated coastal disciplines to be examined across various zones, promoting integration along multiple time and space scales, helping to couple processes with landform responses.
At the coast, dunes provide a physical barrier to flooding during high energy storms, while beaches and nearshore areas help dissipate storm impact through a series of dynamic interactions involving sediment transfers and sometimes rapid morphological changes. Examination of complex interactions between these three interconnected systems has become essential for the understanding, analysis and ultimately, the management of our coasts.
This session welcomes contributions from coastal scientists interested in the measurement and modelling of physical processes and responses within the three sub-units over various spatial and temporal scales. It will highlight the latest scientific developments in our understanding of this part of the planet's geomorphic system and will facilitate knowledge exchange between the submerged (e.g., nearshore waves, currents, and sediment transport) and sub-aerial (e.g., beach and aeolian dune dynamics) zones.

The ocean floor hosts a tremendous variety of forms that reflect the action of a range of tectonic, sedimentary, oceanographic and biological processes at multiple spatio-temporal scales. Many such processes are hazards to coastal populations and offshore installations, and their understanding constitutes a key objective of national and international research programmes and IODP expeditions. High quality bathymetry, especially when combined with sub-seafloor and/or seabed measurements, provides an exciting opportunity to integrate the approaches of geomorphology and geophysics, and to extend quantitative geomorphology offshore. 3D seismic reflection data has also given birth to the discipline of seismic geomorphology, which has provided a 4D perspective to continental margin evolution.
This interdisciplinary session aims to examine the causes and consequences of geomorphic processes shaping underwater landscapes, including submarine erosion and depositional processes, submarine landslides and canyons, sediment transfer and deformation, volcanic activity, fluid migration and escape, faulting and folding, and other processes acting at the seafloor. The general goal of the session is to bring together researchers who characterise the shape of past and present seafloor features, seek to understand the sub-surface and surface processes at work and their impacts, or use bathymetry and/or 3D seismic data as a model input. Contributions to this session can include work from any depth or physiographic region, e.g. oceanic plateaus, abyssal hills, mid-ocean ridges, accretionary wedges, and continental margins (from continental shelves to abyss plains). Datasets of any scale, from satellite-predicted depth to ultra high-resolution swath bathymetry, sub-surface imaging and sampling, are anticipated.

Tsunamis can produce catastrophic damage on vulnerable coastlines, essentially following major earthquakes, landslides, extreme volcanic activity or atmospheric disturbances. After the disastrous tsunamis in 2004 and 2011, tsunami science has been continuously growing and expanding its scope to new fields of research in various domains, and also to regions where the tsunami hazard was previously underestimated.
The spectrum of topics addressed by tsunami science nowadays ranges from the “classical” themes, such as analytical and numerical modelling of different generation mechanisms (ranging from large subduction earthquakes to local earthquakes generated in tectonically complex environments, from subaerial/submarine landslides to volcanic eruptions and atmospheric disturbances), propagation and run-up, hazard-vulnerability-risk assessment, especially with probabilistic approaches able to quantify uncertainties, early warning and monitoring, to more “applied” themes such as the societal and economic impact of moderate-to-large events on coastal local and nation-wide communities, as well as the present and future challenges connected to the global climate change.
This session, co-organized with OS4, SM4, GMPV9, GM and AS, welcomes multidisciplinary as well as focused contributions covering any of the aspects mentioned above, encompassing field data, geophysical models, regional and local hazard-vulnerability-risk studies, observation databases, numerical and experimental modeling, real time networks, operational tools and procedures towards a most efficient warning, with the general scope of improving our understanding of the tsunami phenomenon, per se and in the context of the global change, and our capacity to build safer and more resilient communities.

Tsunamis and storm surges pose significant hazards to coastal communities around the world. Geological investigations, including both field studies and modelling approaches, significantly enhance our understanding of these events. Past extreme wave events may be reconstructed based on sedimentary and geomorphological evidence from low and high energy environments, from low and high latitude regions and from coastal and offshore areas. The development of novel approaches to identifying, characterising and dating evidence for these events supplements a range of established methods. Nevertheless, the differentiation between evidence for tsunamis and storms still remains a significant question for the community. Numerical and experimental modelling studies complement and enhance field observations and are crucial to improving deterministic and probabilistic approaches to hazard assessment. This session welcomes contributions on all aspects of paleo-tsunami and paleo-storm surge research, including studies that use established methods or recent interdisciplinary advances to reconstruct records of past events, or forecast the probability of future events.
Mountain belts are characterized by the fastest rates of physical erosion and chemical weathering around the world, making them one of the best places to observe sediment production (e.g. erosion, weathering) and transport processes. In these settings, varied processes such as rockfall, debris flow, hillslope failure, glacial and periglacial erosion, fluvial erosion, transport and deposition, and chemical weathering operate, often simultaneously, over a wide range of temporal and spatial scales.
As a result, tracking the interactions between denudation, climatic forcing, tectonic activity, vegetation and land use is complex. However, these feedbacks affect both long- and short-term natural surface processes, landscape development, and human interactions with the environment. Many of these processes also pose serious threats to the biosphere, mountain settlements and infrastructure. Therefore, understanding and quantifying rates of erosion, weathering, and deposition within mountain landscapes is a challenging, but crucial research topic in Earth surface processes.
We welcome contributions that (1) investigate the processes of production, mobilisation, transport, and deposition of sediment in mountain landscapes, (2) explore feedbacks between erosion and weathering due to natural and anthropogenic forcings, and (3) consider how these processes contribute to natural hazards specific to mountain landscapes. We invite presentations that employ observational, analytical or modeling approaches in mountain environments across a variety of temporal and spatial scales. We particularly encourage early career scientists to apply for this session.

Mountain glaciations have a long research heritage since they provide an invaluable record for past and present climate change. However, complex glaciological conditions, geomorphological processes and topography can make regional and intra-hemispheric correlations challenging. This problem is further enhanced by ongoing specialisation within the scientific community, whereby working groups often focus on individual aspects or selected mountain regions, thus frequently remain disconnected.
The main incentive for this session is to evaluate the potential of mountain glaciation records and stimulate further discussion to work towards bridging between specialised research communities. Contributions on all relevant aspects are welcomed, including (but not limited to): (a) glacial landforms and glacier reconstructions, (b) dating techniques and glacier chronologies, (c) glaciology and palaeoclimatic interpretations, (d) impacts on ecosystems and human society.
A special regional focus within the session will be dedicated to the Andean Cordillera and topics such as glaciers and palaeoclimatic records from the Andean Cordillera or model-data comparisons that aim to improve projections of future climate and ice-mass behaviour in the Andes and beyond.
Submissions involving interdisciplinary studies, complex interactions or highlighting the specific conditions of mountain glaciations, from continental to maritime regions at any latitude, are encouraged. The potential of related studies should be highlighted alongside strategies to tackle existing challenges as this will enable the session to fully address the diversity of the topic.
In past years, precursors of this session have steadily become a popular platform for everyone interested in the emerging collaborative research network, “The Legacy of Mountain Glaciations”. This network continues to grow, and we hope the 2022 session will provide an opportunity to meet and exchange new ideas and expertise.
Glaciers and volcanoes interact in a number of ways, including instances where volcanic/geothermal activity alters glacier dynamics or mass balance, via subglacial eruptions or the deposition of supraglacial tephra. Glaciers can also impact volcanism, for example by directly influencing mechanisms of individual eruptions resulting in the construction of distinct edifices. Glaciers may also influence patterns of eruptive activity when mass balance changes adjust the load on volcanic systems, the water resources and hydrothermal systems. However, because of the remoteness of many glacio-volcanic environments, these interactions remain poorly understood.
In these complex settings, hazards associated with glacier-volcano interaction can vary from lava flows to volcanic ash, lahars, landslides, pyroclastic flows or glacial outburst floods. These can happen consecutively or simultaneously and affect not only the earth, but also glaciers, rivers and the atmosphere. As accumulating, melting, ripping or drifting glaciers generate signals as well as degassing, inflating/ deflating or erupting volcanoes, the challenge is to study, understand and ultimately discriminate these potentially coexisting signals. We wish to fully include geophysical observations of current and recent events with geological observations and interpretations of deposits of past events. Glaciovolcanoes also often preserve a unique record of the glacial or non-glacial eruptive environment that is capable of significantly advancing our knowledge of how Earth's climate system evolves.
We invite contributions that deal with the mitigation of the hazards associated with ice-covered volcanoes in the Arctic, Antarctic or globally, that improve the understanding of signals generated by ice-covered volcanoes, or studies focused on volcanic impacts on glaciers and vice versa. Research on recent activity is especially welcomed. This includes geological observations e.g. of deposits in the field or remote-sensing data, together with experimental and modelling approaches. We also invite contributions from any part of the world on past activity, glaciovolcanic deposits and studies that address climate and environmental change through glaciovolcanic studies. We aim to bring together scientists from volcanology, glaciology, seismology, geodesy, hydrology, geomorphology and atmospheric science in order to enable a broad discussion and interaction.

Hydrometeorological and geomorphological hazards account for 45% of the fatalities and 79% of global economic losses. Exacerbated by high seismic activity and rugged terrain, the Himalayan landscape is particularly susceptible to generating these events, which often transform into cascading hazards—an initial event causes a downstream hazard chain, e.g. glacial lake outburst floods to debris flows. These hazards interfere with increasing population pressure and expansion of settlements along rivers and new infrastructure developments such as roads and hydropower projects. Rising temperatures and changes in weather patterns in the wake of global warming likely elevate risks from hazards such as landslides, glacial lake outburst floods, riverine and flash floods. The complexity of these hazards and their underlying processes demand scientific efforts and approaches from multiple disciplines.
Multidisciplinary approaches and methodologies are important to holistically estimate and predict hazard events and interactions of multiple hazards, and to understand how vulnerable societies cope and respond to these hazards in the Himalayan region.
This session aims to bring together expertise on approaches, methods, and data to advance the understanding of the impacts and changes in the extremely high mountain landscapes, with a particular focus on the trends of hydro-geomorphological disasters on the Himalayas and their societal impacts.
We welcome contributions from research topics (but not restricted to):
-hydro-geophysical modeling (landslides, glacial lake outburst floods, riverine and flash floods)
-extreme event modeling
-remote-sensing-based observations
-risk/vulnerability assessment
-theories and models of reducing vulnerabilities and adaptation to natural hazards
-innovative data approaches to integrate natural and social science perspective
-recovery to natural hazards, in particular, usage of longitudinal data methods
The session is closely linked to the NHESS special issue “Estimating and Predicting Natural Hazards and Vulnerabilities in the Himalayan Region”. We encourage all session contributors to support this issue.

The geological records of glaciations provide information on the Earth’s past climate and on the efficiency of glaciers in modifying landscapes. Traces of glacial activity are manifested in characteristic depositional and erosional landforms. The focus of this session is to stimulate discussions about the challenges and advances in understanding glaciations and glacial records with a special emphasis on the Quaternary period: How do landscapes and erosion rates evolve under the repeated impact of glaciations? What is the impact of early vs. late glaciations during an ice age? What are the (chrono-)stratigraphic challenges for better constraining glacial periods, especially during earlier periods of the Quaternary? How do climatic conditions affect glaciations and vice versa? How do Quaternary sediments compare to deposits of ice ages earlier in Earth’s history?
Repeated glaciation of an area tends to overprint older landforms and creates fragmented sedimentary successions. For the last glacial cycle, for instance, timing, extent, and driving mechanisms are increasingly well understood, whereas landscape evolution and trends in topographic preconditioning remain poorly constrained for previous glacial cycles. This complexity tends to accentuate when pre-Quaternary glaciations are considered.
We are therefore particularly interested in contributions that demonstrate how some of the limitations imposed by the geological records’ fragmentation can be overcome. For instance, by the following approaches:
1. Uncovering and characterizing glacial deposits, for example preserved in subglacially formed basins (overdeepened basins, tunnel valleys, and fjords), extend the accessible sedimentary record.
2. Modern and ancient analogues help to understand erosion and deposition mechanisms in glacial environments.
3. Relative and absolute chronostratigraphy allows the development of a temporal framework of landscape evolution and environmental conditions.
Contributions may include investigations based on field observations, scientific drilling, geophysical measurements, and/or modelling of present-day, Quaternary, and pre-Quaternary glacial settings. Possible topics cover: (a) glacial and interglacial stratigraphic successions, (b) subglacial erosion and deposition, (c) glaciation chronology, and (d) landscape evolution.

Arid to sub-humid regions are home for >40% of the world’s population, and many prehistoric and historic cultures developed in these regions. Due to the high sensitivity of drylands to small-scale environmental changes and anthropogenic activities, ongoing geomorphological processes but also the Late Quaternary geomorphological and palaeoenvironmental evolution as recorded in sediment archives are becoming increasingly relevant for geological, geomorphological, palaeoenvironmental, palaeoclimatic and geoarchaeological research. Dryland research is constantly boosted by technological methodological advances, and especially by emerging linkages with other climatic and geomorphic systems that allow using dryland areas as indicator-regions of global environmental changes.
This session aims to pool contributions that deal with current and former geomorphological processes and environmental changes, as well as with all types of sediment archives in dryland areas (dunes, loess, slope deposits, fluvial sediments, alluvial fans, lake and playa sediments, desert pavements, soils, palaeosols etc.) at different spatial and temporal scales. Besides case studies from individual regions and archives and review studies, methodical and conceptual contributions are especially welcome in this session, e.g. dealing with the special role of aeolian, fluvial, gravitational and biological processes in dryland environments, sediment preservation, methods to obtain chronological frameworks and process rates, emerging geo-technologies and the role of such processes for current and former societies.

The interactions between aerosols, climate, and weather are among the large uncertainties of current atmospheric research. Mineral dust is an important natural source of aerosol with significant implications on radiation, cloud microphysics, atmospheric chemistry and the carbon cycle via the fertilization of marine and terrestrial ecosystems. In addition, properties of dust deposited in sediments and ice cores are important (paleo-)climate indicators.
This interdivisional session --building bridges between the EGU divisions CL, AS, SSP, BG and GM-- had its first edition in 2004 and it is open to contributions dealing with:
(1) measurements of all aspects of the dust cycle (emission, transport, deposition, size distribution, particle characteristics) with in situ and remote sensing techniques,
(2) numerical simulations of dust on global, regional, and local scales,
(3) meteorological conditions for dust storms, dust transport and deposition,
(4) interactions of dust with clouds and radiation,
(5) influence of dust on atmospheric chemistry,
(6) fertilization of ecosystems through dust deposition,
(7) any study using dust as a (paleo-)climate indicator, including sediment archives in loess, ice cores, lake sediments, ocean sediments and dunes.
We especially encourage the submission of papers that integrate different disciplines and/or address the modelling of past, present and future climates.

Badlands are unique landscapes with intense past or present geomorphological dynamics and high erosion rates, being among the most outstanding and impressive erosion landforms on earth.
Given the problems that follow from the rapidity of geomorphological processes and the high magnitude of erosion of badland areas, there are important associated environmental and management implications (i.e. high sediment transport and water turbidity, loss of biodiversity). Many methods with different degrees of complexity can be used to measure these processes. However, there is not standard protocol for measuring erosion dynamics, and the selection of method mainly depends on several factors as the characteristics of the research group (e.g. number of members, training capacity), financial support (e.g. instrument availability), objectives, and size of the study area. These methods can be mainly considered dynamic or volumetric: (i) dynamic methods aim to measure fluxes from plots (e.g. rainfall simulation, Gerlach troughs), micro-catchments (e.g. collectors), or experimental catchments (e.g. turbidity sensors); while (ii) volumetric methods aim to measure sediment erosion rates through the analysis of topographic changes by sparse observations (e.g. erosion pins, microprofile methods) or by the use of high-resolution topographic survey methods (e.g. Structure from Motion photogrammetry, terrestrial laser scanning). Also, methods should include determining weathering rates of various lithologies in different climate conditions (including both field measurements and simulations in laboratory conditions).
In this session, we would like to gather studies focusing on badland dynamics, especially facing new challenges in measuring geomorphological dynamics and erosion rates: mapping badland evolution and geomorphological dynamics, measuring erosion rates using different methods, discussing new challenges in measuring erosion rates in badlands (including piping erosion), definition of mapping protocol and erosion estimation procedures.
It is now well known that the coupling between tectonics, climate and surface processes governs the dynamics of mountain belts and basin. However, the amplitude of these couplings and their exact impact on mountain building are less understood. First order quantitative constraints on this coupling are therefore needed. They can be provided by geomorphic and sedimentary records including longitudinal river profiles, fluvial terraces, downstream fining trends, growth strata, sediment provenance, sequence stratigraphy, and changing depositional environments. Moreover, the increasing integration of geochronological methods for quantifying erosion rates and source-to-sink sediment transfer with landscape evolution, stratigraphic, climatic, and tectonic models allows to advance our understanding of the interactions between surface processes, climate and tectonic deformation.
We invite contributions that use geomorphic and/or sedimentary records to understand tectonic deformation, climate histories, and surface processes, and welcome studies that address their interactions and couplings at a range of spatial and temporal scales. In particular, we encourage coupled catchment-basin studies that take advantage of numerical/physical modelling, geochemical tools for quantifying rates of surface processes (cosmogenic nuclides, low-temperature thermochronology, luminescence dating) and high resolution digital topographic and subsurface data. We invite contributions that address the role of surface processes in modulating rates of deformation and tectonic style, or of tectonics modulating the response of landscapes to climate change.

Geomorphic and geologic observations at the Earth's surface reflect the combined effects of mantle, lithospheric, and surface processes. Hence surface observations provide important constraints on mantle convection patterns and plume-plate interactions both at plate boundaries and in intraplate settings through space and time. These observations complement geophysical data and are important constraints for theoretical models and numerical simulations. For instance, at plate boundaries, surface observations can provide key constraints on the rheology and kinematics of lithospheric and mantle processes. In both plate boundary and intraplate settings, mantle plumes can trigger continental rifting and break-up, subduction initiation, orogeny, microcontinent formation, and/or the development of dynamic topography. However, using surface observations to constrain mantle processes is complicated by (1) our as yet incomplete understanding of how mantle dynamics manifest at the surface, and (2) spatio-temporal variations in tectonic processes, climate, isostatic adjustment, lithology, biota, and human alteration of landscapes. In this session, we aim to bring together researchers interested in mantle-surface and plume-plate interactions. We welcome studies that cover a range of techniques from data-driven approaches to numerical modelling or laboratory experiments.
We hope this session will provide opportunities for presenters from a range of disciplines, demographics, and stages of their scientific career to engage in this exciting and emerging problem in Earth Science.
Continental rifting is a complex process spanning from the inception of extension to continental rupture or the formation of a failed rift. This session aims at combining new data, concepts and techniques elucidating the structure and dynamics of rifts and rifted margins. We invite submissions highlighting the time-dependent evolution of processes such as: initiation and growth of faults and ductile shear zones, tectonic and sedimentary history, magma migration, storage and volcanism, lithospheric necking and rift strength loss, influence of the pre-rift lithospheric structure, rift kinematics and plate motion, mantle flow and dynamic topography, as well as break-up and the transition to sea-floor spreading. We encourage contributions using multi-disciplinary and innovative methods from field geology, geochronology, geochemistry, petrology, seismology, geodesy, marine geophysics, plate reconstruction, or numerical or analogue modelling. Special emphasis will be given to presentations that provide an integrated picture by combining results from active rifts, passive margins, failed rift arms or by bridging the temporal and spatial scales associated with rifting.

Transform faults are one of the three types of plate boundaries required for Earth-like plate tectonics to operate. In these locations, plates move laterally in relation to each other without significant creation or destruction of plate material. Transform plate boundaries played a fundamental role in the development of the theory of plate tectonics. The concept of transform fault was introduced by Tuzo Wilson as the final piece of a puzzle that allowed connecting ridges to convergent zones and close the circumference of lithospheric plates. Wilson recognized that transform faults were different from the already known continental transcurrent faults (or nonlithospheric strike-slip faults). The term transform plate boundary is since then been used to define a lithospheric strike-slip fault zone that constitutes a plate boundary. The term is also used more loosely to define strike-slip boundaries of diffuse tectonic blocks or microplates. At smaller orders, strike-slip faults exist in all kinds of environments and at all scales, accommodating the lateral movement of tectonic blocks and linking other kinds of faults. Transform plate boundaries can exist in both continental or oceanic lithosphere, leading to markedly different strain distribution patterns and seismic activity. This is particularly true for the case of oceanic transform faults, which result from the own growth of the plates. Due to their remote locations, the rheological structure and behavior of oceanic transform faults are still largely unknown. The fact that they exist in oceanic environments suggests that they are prone to constant fluid circulation and alteration, potentiated by the chemical reactions between rocks and circulating fluids. Transform faults have also traditionally been perceived as places of low to moderate magnitude seismicity, but recent events have shown that these structures can generate very high magnitude hazardous events. Examples include the 2010 Haiti earthquake and the 1941 M 8.4 earthquake along the Gloria Fault. In this session, we aim to discuss the evolution of oceanic and continental transform and strike-slip faults. We welcome studies on structural geology, marine geology, geochemistry, petrology, remote sensing, tectonics, seismology and hazards, as well as modelling studies, using both analogue and numerical approaches. Associated processes such as shear localization, serpentinisation, biogenic activity, fluid migration and extrusion are also very welcome.

Geologic processes are generally too slow, too rare, or too deep to be observed in-situ and to be monitored with a resolution high enough to understand their dynamics. Analogue experiments and numerical simulation have thus become an integral part of the Earth explorer's toolbox to select, formulate, and test hypotheses on the origin and evolution of geological phenomena.
To foster synergy between the rather independently evolving experimentalists and modellers we provide a multi-disciplinary platform to discuss research on tectonics, structural geology, rock mechanics, geodynamics, volcanology, geomorphology, and sedimentology.
We therefore invite contributions demonstrating the state-of-the-art in analogue and numerical / analytical modelling on a variety of spatial and temporal scales, varying from earthquakes, landslides and volcanic eruptions to sedimentary processes, plate tectonics and landscape evolution. We especially welcome those presentations that discuss model strengths and weaknesses, challenge the existing limits, or compare/combine the different modelling techniques to realistically simulate and better understand the Earth's behaviour.

The rates and dates of processes occurring at tectonic-plate scale can be quantified using evidence derived from actively deforming settings, including geomorphic markers (e.g., topography and rivers, fluvial deposits, marine terraces) and sedimentary archives (e.g., syntectonic sedimentation, stratigraphic evidence).
When used as key natural laboratories at adequate time spans, such evidence provides essential clues to understand large-scale tectonics. These focused studies may contribute to unravel the motion, deformation, and evolution of tectonic plates, as well as changes in their potential geodynamics and boundary conditions.
We invite contributions focusing on understanding the dynamics and evolution of deforming plate interiors and active plate boundaries through interdisciplinary, geomorphic, or sedimentary data-based approaches. We welcome all types of studies that aim to quantify the rates of active plate deformation and the dates of tectonic events, regardless of their spatio-temporal scale or methodology.

The evolution of extensional tectonic settings is often envisioned as an in-plane process. Yet in nature extensional settings are often characterised by processes occurring in 3D and over protracted timescales. Their complex deformation histories can be attributed to superimposed events that involve pre-existing heterogeneities with different orientations, temporal changes in plate motion or, very often, a combination of the above. These factors result in multi-phase rifting, rotational or oblique rift kinematics, complex fault growth and interaction, lateral variations in structural style and rift propagation, as well as intricate strain partitioning patterns, among others. These complexities are commonly observed in both ancient and currently active extensional settings, but deciphering the temporal evolution of inherently 3D tectonic systems from limited (and often 2D) datasets can pose a significant challenge.
The aim of this session is to bring together new research from disciplines focussing on the 3D evolution of extensional tectonic settings at various spatio-temporal scales, with important implications for basin development, magmatism and surface processes. We encourage contributions from a wide range of fields, including geophysics, paleomagnetism, geodesy, geochronology, tectonics, structural geology, and analogue and numerical modelling in order to promote cross-disciplinary discussions that lead to new insights on the topic.

Integrating sedimentology, geomorphology, and structural geology to better understand the weathering, erosion, transfer, and storage of sediment from source to sink is an inherently interdisciplinary field. Disentangling signals and their landscape response has a breadth of implications within managing present-day resources, reconstructing paleoenvironments, and fostering understanding of the evolution of our planet. More recently, anthropogenic actions add further complexity within signal interpretations and alter landscape dynamics.
Within the source to sink approach, sediments are generally produced in mountainous areas through weathering and transported via sediment routing systems (SRS) to a zone of final deposition. Terrestrially derived sediments in sedimentary archives are regularly used to reconstruct past climatic or tectonic conditions. Environmental reconstructions are based on the assumption that perturbations in climatic or tectonic conditions generate signals within the transported sediment. However, experimental and numerical studies have shown that not all signals are faithfully transmitted, but can be modified, buffered or even lost during transport along the SRS. Therefore, quantifying the spatial and temporal constraints of signal transfer and storage (eg: transience vs steady-state conditions and basin response times) are just as critical to sedimentary interpretation as the understanding the magnitude and duration of the source signal (eg: periodicity of the environmental forcing).
We would like to encourage discussion and build an international community between researchers within academic circles and industry who are applying a comprehensive source to sink systems approach. We are especially interested in sedimentary proxy generation during environmental changes (eg: surface and regolith biogeochemical weathering or physical grain size signals), transport (eg: modern autogenic dynamics, palaeohydraulics, and signal tracing), and archiving (eg: reservoir prediction) controls on the SRS. Contributions across diverse approaches (eg. modeling to field-based studies), environments (continental to marine), and time scales (human to geologic) are encouraged.
It becomes increasingly accepted that many regions all over the world are experiencing an increase in the frequency of extreme rainfall events and potentially in their properties. For predicting the impact of future climate change on the landscape, it is therefore vital to understand the dynamics of surface processes under extreme events. Furthermore, focusing on the conditions necessary for extreme events to occur can provide key insights into past changes in climate at different time scales. Extreme storms cause a multitude of hydrogeomorphic and natural hazards responses, including floods and respective fluvial responses, hillslope erosion and failures, and debris flows from slopes into fluvial systems. Measuring, evaluating, and predicting the impacts of extreme rainstorms, however, remains challenging due to the difficult-to-predict and complex nature of storms and rainfall-surface interactions.
This interdisciplinary session focuses on the causative chain which links the deterministic and mostly stochastic nature of the synoptic to meso/regional and watershed scales of extreme storms, to their respective transformation into watershed, slope, and stream hydrology, and to their geomorphic impact. We welcome studies from all the parts of this chain, from all climates, and at all temporal scales, that are focusing on the hydrological responses to extreme events and on their imprints on the landscape through erosion and sediment movement. We favor studies with emphasis on the final noticeable impact of extreme events on the landscape and/or on the integrated long-term consequences of extreme storm regime on landscape evolution. Especially, we encourage studies presenting new physical/stochastic modeling approaches that explicitly investigated the impact of extreme events on the landscape.

Present-day glacial and periglacial processes in cold regions, i.e. arctic and alpine environments, provide modern analogues to processes and climatic changes that took place during the Pleistocene, including gradual retreat or collapse of ice sheets and mountain glaciers, and thawing and shrinking of low-land permafrost. Current geomorphological and glaciological changes in mid-latitude mountain ranges could also serve as a proxy for future changes in high-latitude regions within a context of climate change. Examples are speed-up or disintegration of creeping permafrost features or the relictification of rock glaciers.
For our session we invite contributions that either:
1. investigate present-day glacial and/or periglacial landforms, sediments and processes to describe the current state, to reconstruct past environmental conditions and to predict future scenarios in cold regions; or
2. have a Quaternary focus and aim at enhancing our understanding of past glacial, periglacial and paraglacial processes, also through the application of dating techniques.
Case studies that use a multi-disciplinary approach (e.g. field, laboratory and modelling techniques) and/or that highlight the interaction between the glacial, periglacial and paraglacial cryospheric components in cold regions are particularly welcome.

Glacial Isostatic Adjustment (GIA) describes the dynamic response of the solid Earth to ice sheet glaciation/deglaciation, which affects the spatial and temporal sea level changes, and induces surface deformation, gravitational field variation and stress changes in the subsurface. The process is influenced by the ice sheet characteristics (e.g., extent, volume, grounding line) and solid Earth structure. With more observational data (e.g., relative sea-level data, GPS data, tide gauges, terrestrial and satellite gravimetry, glacially induced faults) are available/standardized, we can better investigate the interactions between the ice sheets, solid Earth and sea levels, and reveal the ice sheet and sea-level evolution histories and rheological properties of the Earth.
This session invites contributions discussing observations, analysis, and modelling of ice sheet dynamics, solid Earth response, and the resulting global, regional and local sea-level changes and land deformation, including paleo ice sheet and paleo sea-level investigations, geodetic measurements of crustal motion and gravitational change, GIA modelling with complex Earth models (e.g., 3D viscosity, non-linear rheologies) and coupled ice-sheet/Earth modelling, investigations on glacially triggered faulting as well as the Earth’s elastic response to present-day ice mass changes. We also welcome abstracts that address the future ice sheets/shelves evolution and sea-level projection as well as GIA effects on oil migration and nuclear waste repositories. Contributions related to both polar regions and previously glaciated regions are welcomed. This session is co-sponsored by the SCAR sub-committee INSTANT-EIS, Earth - Ice - Sea level, in view of instabilities and thresholds in Antarctica https://www.scar.org/science/instant/home/.
The increase of climate-related hazards has been driven by climate change, increasing human activities and infrastructure development, particularly in vulnerable areas. More efforts should be directed towards effective disaster risk management to reduce damages and losses, focusing on hazard, vulnerability, and risk mapping. Remote Sensing (RS) and Geographic Information Systems (GIS) are powerful tools in mapping change and rate of change concerning natural hazards, particularly in data-scarce environments, thanks to the great advantage of sensing extended areas at low cost and with regular revisit capability. Furthermore, satellite RS offers the opportunity to gain fresh insights into biophysical environments through satellite systems' spatial, temporal, spectral, and radiometric resolutions. The advantages of RS are further supported by the analytical and geospatial data integration capabilities of GIS.
On the other hand, proximal RS offers a unique opportunity to observe processes characterized by fast dynamics and complex geometries and provides data at ultra-high temporal and spatial resolution. The number of proximal RS solutions currently adopted to study and monitor natural hazards has progressively increased in the last decades. Nowadays, UAV, terrestrial radar interferometry, and digital photogrammetry are among the most diffuse proximal systems adopted to identify precursor elements for detailed hazard assessment and support decision-makers during emergencies. In particular, the use of these systems helps create high-resolution 3D models of the study area and monitor natural hazards. The adoption of multi-scale and multi-sensor approaches can be beneficial for studying the same phenomenon from different points of view and can support a detailed description of the studied process and the most critical parameters that can be adopted for its characterization. The availability of many technical solutions represents an additional value, but the lack of defined methodologies can limit these systems' standardized use, particularly during emergencies. This session aims to explore the use of satellite and proximal RS techniques and GIS analysis in different scenarios related to natural hazards and impact analysis and mitigation, including the preliminary characterization of potential dangerous processes, the evaluation of the elements at risk, the management of the emergency phase and the support of recovery and post-emergency reconstruction.
The Planetary Geomorphology session aims to bring together geomorphologists who study the Earth with those who work on other bodies such as Mars, Venus, Mercury, the Moon, icy satellites of the outer solar system, comets, and/or asteroids. Studies applicable to landscapes on any scale on any solid body are welcome. We particularly encourage those who use Earth analogues or laboratory/numerical simulation to submit their work. Considered processes could include aeolian, volcanic, tectonic, fluvial, glacial, periglacial, or "undetermined" ones. We especially welcome contributions from early-career scientists and geomorphologists who are new to planetary science.

Aeolian processes are active on various planetary surfaces throughout the Solar System and yield similar landforms across a wide range of spatial scales despite differences in atmospheric and surface properties. They are typically associated with the movement of sediments driven by an atmospheric flow but can also be controlled by other modes of matter transport such as ice sublimation. The combination of terrestrial and extra-terrestrial experiments and observations provides the opportunities as well as challenges for improving our fundamental theories and numerical models for better understanding of these aeolian environments. Innovations in instrumentation and experimental techniques continue to yield novel insights on Earth, while space missions and remote probes constantly deliver new and surprising evidence from aeolian environments on other planetary bodies. This session welcomes research on all aspects of aeolian processes and landforms, contemporary and ancient, on planetary surfaces across the Solar System.

Documenting the diversity of human responses and adaptations to climate, landscapes, ecosystems, natural disasters and the changing natural resources availability in different regions of our planet, cross-disciplinary studies in Geoarchaeology provide valuable opportunities to learn from the past. Furthermore, human activity became a major player of global climatic and environmental change in the course of the late Quaternary, during the Anthropocene. Consequently, we must better understand the archaeological records and landscapes in context of human culture and the hydroclimate-environment nexus at different spatial and temporal scales. This session seeks related interdisciplinary papers and specific geoarchaeological case-studies that deploy various approaches and tools to address the reconstruction of former human-environmental interactions from the Palaeolithic period through the modern. Topics related to records of the Anthropocene from Earth and archaeological science perspectives are welcome. Furthermore, contributions may include (but are not limited to) insights about how people have coped with environmental disasters or abrupt changes in the past; defining sustainability thresholds for farming or resource exploitation; distinguishing the baseline natural and human contributions to environmental changes. Ultimately, we would like to understand how strategies of human resilience and innovation can inform our modern strategies for addressing the challenges of the emerging Anthropocene, a time frame dominated by human modulation of surface geomorphological processes and hydroclimate.

Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

Urban areas are at risk from multiple hazards, including urban flooding, droughts and water shortages, sea level rise, disease spread and issues with food security. Consequently, many urban areas are adapting their approach to hazard management and are applying Green Infrastructure (GI) solutions as part of wider integrated schemes.
This session aims to provide researchers with a platform to present and discuss the application, knowledge gaps and future research directions of urban GI and how sustainable green solutions can contribute towards an integrated and sustainable urban hazard management approach. We welcome original research contributions across a series of disciplines with a hydrological, climatic, soil sciences, ecological and geomorphological focus, and encourage the submission of abstracts which demonstrate the use of GI at a wide range of scales and geographical distributions. We invite contributions focusing on (but not restricted to):
· Monitored case studies of GI, Sustainable Drainage Systems (SuDS) or Nature Based Solutions (NBS), which provide an evidence base for integration within a wider hazard management system;
· GIS and hazard mapping analyses to determine benefits, shortcomings and best management practices of urban GI implementation;
· Laboratory-, field- or GIS-based studies which examine the effectiveness or cost/benefit ratio of GI solutions in relation to their wider ecosystem potential;
· Methods for enhancing, optimising and maximising GI system potential;
· Innovative and integrated approaches or systems for issues including (but not limited to): bioretention/stormwater management; pollution control; carbon capture and storage; slope stability; urban heat exchange, and; urban food supply;
· Catchment-based approaches or city-scale studies demonstrating the opportunities of GI at multiple spatial scales;
· Rethinking urban design and sustainable and resilient recovery following crisis onset;
· Engagement and science communication of GI systems to enhance community resilience.

The session gathers geoscientific aspects such as dynamics, reactions, and environmental/health consequences of radioactive materials that are massively released accidentally (e.g., Chernobyl and Fukushima nuclear power plant accidents, wide fires, etc.) and by other human activities (e.g., nuclear tests).
The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Thus, the radioactive contamination problem is multi-disciplinary. In fact, this topic involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic and ecosystem, and its relations with human and non-human biota. The topic also involves hazard prediction and nowcast technology.
By combining 35 years (> halftime of Cesium 137) monitoring data after the Chernobyl Accident in 1986, 10 years dense measurement data by the most advanced instrumentation after the Fukushima Accident in 2011, and other events, we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents.
The following specific topics have traditionally been discussed:
(a) Atmospheric Science (emissions, transport, deposition, pollution);
(b) Hydrology (transport in surface and ground water system, soil-water interactions);
(c) Oceanology (transport, bio-system interaction);
(d) Soil System (transport, chemical interaction, transfer to organic system);
(e) Forestry;
(f) Natural Hazards (warning systems, health risk assessments, geophysical variability);
(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).
The session consists of updated observations, new theoretical developments including simulations, and improved methods or tools which could improve observation and prediction capabilities during eventual future nuclear emergencies. New evaluations of existing tools, past nuclear contamination events and other data sets also welcome.

Karst environments are characterized by distinctive landforms and unique hydrological behaviors. Karst systems are extremely complex, heterogeneous and very difficult to manage, because their formation and evolution are controlled by a wide range of geological, hydrological, geochemical and biological processes, and are extremely variable in time and space. Furthermore, karst systems are highly vulnerable to a variety of hazards, due to the direct connection between the surface and subsurface through the complex networks of conduits and caves.
In karst, any interference is likely to have irreversible impacts and disturb the natural balance of the elements and processes. The great variability and unique connectivity may result in serious engineering problems: on one hand, karst groundwater resources are easily contaminated by pollution because of the rapidity of transmission through conduit flow, and remediation action, when possible, could be very expensive and require a long time; on the other hand, the presence of karst conduits that weakens the strength of the rock mass may lead to serious natural and human-induced hazards. The design and development of engineering projects in karst environments thus should necessarily require: 1) an enhanced understanding of the natural processes governing the initiation and evolution of karst systems through both field and modelling approaches, and 2) specific interdisciplinary approaches aimed at mitigating the detrimental effects of hazardous processes and environmental problems.
This session calls for abstracts on research from karst areas worldwide related to geomorphology, hydrogeology, engineering geology, hazard mitigation in karst environments in the context of climate change and increasing human disturbance.

Meet editors of internationally renowned journals in geo- and biogeoscience and gain exclusive insights into the publishing process. After a short introduction into some basics, we will start exploring various facets of academic publishing with short talks given by the editors on
- What are the duties and roles of editors, authors and reviewers?
- How to choose a suitable journal for your manuscript and what is important for early career authors?
- How can early career scientists get involved in successful peer-reviewing?
- What is important for appropriate peer-reviewing?
- What are ethical aspects and responsibilities of publishing?
Together with the audience and the editors, we will have an open discussion of the key steps and factors shaping the publication process of a manuscript. This short course aims to provide early career scientists across several EGU divisions (e.g. AS, BG, CL, GM, NH, SSP and SSS) the opportunity of using first hand answers of experienced editors of international journals to successfully publish their manuscripts and get aware of the potentials and pitfalls in academic publishing.

Publishing your research in a peer reviewed journal is essential for a career in research. All EGU-affiliated journals are fully open access which is great, but the unique open discussion and transparent peer review process can be daunting for first time submitters and early career scientists. This short course will cover all you need to know about the publication process from start to end for EGU journals, and give you a chance to ask the editors some questions. This includes: what the editor looks for in your submitted paper, how to deal with corrections or rejections, and how best to communicate with your reviewers and editors for a smooth transition from submission to publication. Ample time will be reserved for open discussion for the audience to ask questions to the editors, and for the editors to suggest ‘top tips’ for successful publication. This course is aimed at early-career researchers who are about to step into the publication process, and those who are yet to publish in EGU journals. Similarly, this course will be of interest to those looking to get involved in the peer-review process through reviewing and editing. This short course is part of the “Meet the EGU Journal Editors” webinar series that was held prior to the EGU General Assembly 2022.

We are excited to welcome our panelists for this session, who will be representing their respective journals:
This 105-minute short course aims to introduce non-geologists to structural and petrological geological principles, which are used by geologists to understand system earth.
The data available to geologists is often minimal, incomplete and representative for only part of the geological history. Besides learning field techniques to acquire and measure data, geologists need to develop a logical way of thinking to close gaps in the data to understand the system. There is a difference in the reality observed from field observation and the final geological model that tells the story.
In this course we briefly introduce the following subjects:
1) Grounding rocks: Introduction to the principles of geology.
2) Collecting rocks: The how, what, and pitfalls of field data acquisition.
3) Failing rocks: From structural field data to (paleo-)stress analysis.
4) Dating rocks: Absolute and relative dating of rocks using petrology and geochronology methods.
5) Shaping rocks: The morphology of landscapes as tectonic constraints
6) Crossing rocks over: How geology benefits from seismology, geodynamic and geodesy research, and vice-versa.
7) Q&A!
Our aim is not to make you the next specialist in geology, but we would rather try and make you aware of the challenges a geologist faces when they go out into the field. Additionally, the quality of data and the methods used nowadays are addressed to give other earth scientists a feel for the capabilities and limits of geological research. This course is given by Early Career Scientist geologists and geoscientists and forms a quartet with the short courses on ‘Geodynamics 101 (A&B)’, ‘Seismology 101’, and ‘Geodesy 101’. For this reason, we will also explain what kind of information we expect from the fields of seismology, geodynamics and geodesy, and we hope to receive some feedback in what kind of information you could use from our side.

The work of scientists does not end with publishing their results in peer-reviewed journals and presenting them at specialized conferences. In fact, one could argue that the work of a scientist only starts at this point: outreach. What does outreach mean? Very simply, it means to engage with the wider (non-scientific) public about science. There are many ways to do outreach, including blogging and vlogging, using social media, writing for a science dissemination journal, participating as a speaker at local science festivals, organising open days in the laboratory, and so on.
With this short course, we aim to give practical examples of different outreach activities, how to start an outreach project and tips and suggestions from personal and peers’ experiences. Specific attention will be paid to science communication issues, including the proper ‘translation’ of the jargon of science into language the public understands, the selection of the content being conveyed, and the best format in which it is presented according to the different targets (policymakers, the general public, school-age children, etc.).
In the last part of the course, you will work singularly to come up with an outreach idea based on your research. You may use it on your next proposal; you never know!

Rationale
The proper and deep education on ethical issues in geosciences has been evolving in recent times, although not as quickly and deeply as necessary. Many of the professionals dedicated to Earth Sciences have been not in touch with such new concepts and tendencies. Geoethics is the research and reflection on the values that underpin appropriate behaviors and practices, wherever human activities interact with the Earth system. It provides a framework to define ethical professional behaviors in Earth sciences and engineering and to determine how these should be put into practice for the benefit of environment and society. The Short Course is directed towards introducing and training Earth scientists in those new concepts and ideas as well as exposing the perspectives of this field. Social-ecological Systems and the anthropic impact on land, ocean, and atmosphere are at the cores issues to be discussed under the umbrella of geoethics, as a tool to cope with Climate Changes and other earth-society related challenges.
Completing this course, participants
1. Will know the basic principles of ethics and how these lead to geoethics
2. Will be aware of the dilemmas involved in making geoethical decisions
3. Will have gained some experience in taking a geoethical approach to real world cases
Course Content: (provisional):
1. From Ethics to geoethics: definition, values, tools
2. Responsible conduct of research and professionalism

Globally, geoscience and research analytical laboratories collect ever increasing volumes of data: an acute challenge now is how to collate, store and make these data accessible in a standardised, interoperable and machine-accessible form that is FAIR. Many solutions today are bespoke and inefficient, lacking, for example, unique identification of samples, instruments, and data sets needed to trace the analytical history of the data; and there are few community agreed standards to facilitate sharing and interoperability between systems.
The push for a solution is being driven by publishers and journals who increasingly require researchers to provide access to the supporting data from a trusted repository prior to publication of manuscripts or finalisation of grants. We urgently need community development of systems to facilitate easy and efficient management of geoanalytical laboratory data. We need to address the lack of global standards, best practices and protocols for analytical data management and exchange, in order for scientists to better share their data in a global network of distributed databases. Buy-in from users and laboratory managers/technicians is essential in order to develop efficient and supported mechanisms.
This session seeks a diversity of papers from any initiative around the world that organises and structures sample/field metadata and research laboratory data at any scale to facilitate sharing and processing of geoanalytical data. We welcome papers on data and metadata standardisation efforts and papers on data management and systems that transfer data/metadata from instruments to shared data systems and relevant persistent repositories. Efforts on how to collate, curate, share and publicise sample/data collections as well as papers on the social dynamics of building sharing systems/frameworks are also welcome.

Remote sensing measurements, acquired using different platforms - ground, UAV, aircraft and satellite - have increasingly become rapidly developing technologies to study and monitor Earth surface, to perform comprehensive analysis and modeling, with the final goal of supporting decision systems for ecosystem management. The spectral, spatial and temporal resolutions of remote sensors have been continuously improving, making environmental remote sensing more accurate and comprehensive than ever before. Such progress enables understanding of multiscale aspects of high-risk natural phenomena and development of multi-platform and inter-disciplinary surveillance monitoring tools. The session welcomes contributions focusing on present and future perspectives in environmental remote sensing, from multispectral/hyperspectral optical and thermal sensors. Applications are encouraged to cover, but not limited to, the monitoring and characterization of environmental changes and natural hazards from volcanic and seismic processes, landslides, and soil science. Specifically, we are looking for novel solutions and approaches including the topics as follows: (i) state-of-the-art techniques focusing on novel quantitative methods; (ii) new applications for state-of-the-art sensors, including UAVs and other close-range systems; (iii) techniques for multiplatform data fusion.
This session is open to all contributions in biogeochemistry and ecology where stable isotope techniques are used as analytical tools, with foci both on stable isotopes of light elements (CHONS …) and new systems (clumped and metal isotopes). We welcome studies from both terrestrial and aquatic (including marine) environments as well as methodological, experimental and theoretical studies that introduce new approaches or techniques (including natural abundance work, labelling studies, multi-isotope approaches).

Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

Recent advances in image collection, e.g. using unoccupied aerial vehicles (UAVs), and topographic measurements, e.g. using terrestrial or airborne LiDAR, are providing an unprecedented insight into landscape and process characterization in geosciences. In parallel, historical data including terrestrial, aerial, and satellite photos as well as historical digital elevation models (DEMs), can extend high-resolution time series and offer exciting potential to distinguish anthropogenic from natural causes of environmental change and to reconstruct the long-term evolution of the surface from local to regional scale.
For both historic and contemporary scenarios, the rise of techniques with ‘structure from motion’ (SfM) processing has democratized data processing and offers a new measurement paradigm to geoscientists. Photogrammetric and remote sensing data are now available on spatial scales from millimetres to kilometres and over durations of single events to lasting time series (e.g. from sub-second to decadal-duration time-lapse), allowing the evaluation of event magnitude and frequency interrelationships.
The session welcomes contributions from a broad range of geoscience disciplines such as geomorphology, cryosphere, volcanology, hydrology, bio-geosciences, and geology, addressing methodological and applied studies. Our goal is to create a diversified and interdisciplinary session to explore the potential, limitations, and challenges of topographic and orthoimage datasets for the reconstruction and interpretation of past and present 2D and 3D changes in different environments and processes. We further encourage contributions describing workflows that optimize data acquisition and processing to guarantee acceptable accuracies and to automate data application (e.g. geomorphic feature detection and tracking), and field-based experimental studies using novel multi-instrument and multi-scale methodologies. This session invites contributions on the state of the art and the latest developments in i) modern photogrammetric and topographic measurements, ii) remote sensing techniques as well as applications, iii) time-series processing and analysis, and iv) modelling and data processing tools, for instance, using machine learning approaches.
The nature of Earth’s lithospheric mantle is largely constrained from the petrological and geochemical studies of xenoliths. They are complemented by studies of orogenic peridotites and ophiolites, which show the space relationships among various mantle rock types, missing in xenoliths. Mantle xenoliths from cratonic regions are distinctly different from those occurring in younger non-cratonic areas. Percolation of melts and fluids through the lithospheric mantle significantly modifies its petrological and geochemical features, which is recorded in mantle xenoliths brought to the surface by oceanic and continental volcanism. Basalts and other mantle-derived magmas provide us another opportunity to study the chemical and physical properties the mantle. These various kinds of information, when assembled together and coupled with experiments and geophysical data, enable the understanding of upper mantle dynamics.
This session’s research focus lies on mineralogical, petrological and geochemical studies of mantle xenoliths, orogenic and ophiolitic peridotites and other mantle derived rocks. We strongly encourage the contributions on petrology and geochemistry of mantle xenoliths and other mantle rocks, experimental studies, the examples and models of mantle processes and its evolution in space and time.

Subduction is one of the primary mechanisms of fluid and element cycling between
the surface and mantle in the Earth. During subduction, metamorphism in the
downgoing plate and the consequent expulsion of fluids and generation of melts
drives mineralogical, geochemical, and rheological changes affecting the mechanical
behaviour of the subducting zone system. These fluids and melts play a key role in
the long-term geochemical evolution of the Earth by preferentially fractionating
elements from the slab and introducing them to the mantle wedge, volcanic arc, and
forearc. This process is particularly relevant for volatiles, such as carbon, which can have a profound influence on the habitability of the Earth's surface. This session aims to bring together the petrology, geochemistry, geodynamics, tectonics, and geochronology community by linking subduction zone inputs, outputs and mechanisms over a range of length and timescales. We especially encourage studies that constrain the conditions, durations, and geochemical evolution of metamorphic, metasomatic, and magmatic processes leading to the transfer of material from the slab into the mantle wedge, forearc, arc, and deep mantle. We encourage participation from scientists from all backgrounds and levels of experience.

Subduction drives plate tectonics, generating the major proportion of subaerial volcanism, releasing >90% seismic moment magnitude, forming continents, and recycling lithosphere. Numerical and laboratory modeling studies have successfully built our understanding of many aspects of the geodynamics of subduction zones. Detailed geochemical studies, investigating compositional variation within and between volcanic arcs, provide further insights into systematic chemical processes at the slab surface and within the mantle wedge, providing constraints on thermal structures and material transport within subduction zones. However, with different technical and methodological approaches, model set-ups, inputs, and material properties, and in some cases conflicting conclusions between chemical and physical models, a consistent picture of the controlling parameters of subduction-zone processes has so far not emerged.
This session aims to follow subducting lithosphere on its journey from the surface down into the Earth's mantle and to understand the driving processes for deformation and magmatism in the over-riding plate. We aim to address topics such as: subduction initiation and dynamics; changes in mineral breakdown processes at the slab surface; the formation and migration of fluids and melts at the slab surface; primary melt generation in the wedge; subduction-related magmatism; controls on the position and width of the volcanic arc; subduction-induced seismicity; mantle wedge processes; the fate of subducted crust, sediments and volatiles; the importance of subducting seamounts, LIPs, and ridges; links between near-surface processes and slab dynamics and with regional tectonic evolution; slab delamination and break-off; the effect of subduction on mantle flow; and imaging subduction zone processes.
With this session, we aim to form an integrated picture of the subduction process, and invite contributions from a wide range of disciplines, such as geodynamics, modeling, geochemistry, petrology, volcanology, and seismology, to discuss subduction zone dynamics at all scales from the surface to the lower mantle, or in applications to natural laboratories.

The origin and evolution of the continental lithosphere is closely linked to changes in mantle dynamics through time, from its formation through melt depletion to multistage reworking and reorganisation related to interaction with melts formed both beneath and within it. Understanding this history is critical to constraining terrestrial dynamics, element cycles and metallogeny. We welcome contributions dealing with: (1) Reconstructions of the structure and composition of the lithospheric mantle, and the influence of plumes and subduction zones on root construction; (2) Interactions of plume- and subduction-derived melts and fluids with the continental lithosphere, and the nature and development of metasomatic agents; (3) Source rocks, formation conditions (P-T-fO2) and evolution of mantle melts originating below or in the mantle lithosphere; (4) Deep source regions, melting processes and phase transformation in mantle plumes and their fluids; (5) Modes of melt migration and ascent, as constrained from numerical modelling and microstructures of natural mantle samples; (6) Role of mantle melts and fluids in the generation of hybrid and acid magmas.These topics can be illuminated using the geochemistry and fabric of mantle xenoliths and orogenic peridotites, mantle-derived melts and experimental simulations.

Processes responsible for formation and development of the early Earth (> 2500Ma) are not well understood and strongly debated, reflecting in part the poorly preserved, altered, and incomplete nature of the geological record from this time.
In this session we encourage the presentation of new approaches and models for the development of Earth's early crust and mantle and their methods of interaction. We encourage contributions from the study of the preserved rock archive as well as geodynamic models of crustal and mantle dynamics so as to better understand the genesis and evolution of continental crust and the stabilization of cratons.
We invite abstracts from a large range of disciplines including geodynamics, geology, geochemistry, and petrology but also studies of early atmosphere, biosphere and early life relevant to this period of Earth history.

Cratons form the ancient, stable cores of most of the Earth’s continents. Knowledge about the present-day architecture of cratons is the key to understand the evolution of continental plates. In addition to that, cratons concentrate many economically relevant mineral deposits, which are indispensable for a modern society. For many cratonic regions however, little is still known about the present-day lithospheric structure and how it evolved since the Archean, mainly due to their remoteness and harsh local environmental conditions. Ongoing data acquisition, as well as the usage and optimization of
remote and passive techniques have shed new light on the lithospheric architecture of cratonic regions. Recent advancements across several disciplines show that cratons are more varied and fragmented than previously assumed, which has strong implications for geodynamic interactions with the convective mantle and long-term stability.
In this session, we welcome contributions across different scales that describe the cratonic lithosphere and its evolution with time, up to the dawn of plate tectonics. We aim to address topics like: characterization and evolution of cratonic crust and lithosphere; coupling between cratonic crust and mantle; mechanisms to form, maintain and destroy cratonic roots; craton-plume interaction; the role of cratons in supercontinent configurations; connection of cratons to mineral deposits.
We would like to raise discussions within a multidisciplinary session and therefore welcome contributions across a wide range of disciplines, including, but not limited to geodynamics, geology, tectonics, seismology, gravity, geochemistry, petrology, as well as joint approaches.

The present state of Earth and other rocky planets are an expression of dynamical and chemical processes occurring throughout their history. In particular, giant impacts, core formation and magma-ocean crystallisation and other processes occurring in the early solar system set the stage for the long-term evolution of terrestrial planets. These early processes can happen simultaneously or in recurring stages, and are ultimately followed by progressive crustal growth, long-term mantle mixing/differentiation, core-mantle interaction, as well as inner-core crystallization. The rock-record, through geochemistry and magnetism, is used to interrogate changes in the tectono-thermal regime of Earth’s interior through time, while seismic imaging and gravity data, for instance, provide a snapshot of processes occurring in the contemporary mantle, crust and core. These classes of observations may be linked through geodynamic models, whose accuracy is underpinned by the physical properties (e.g., viscosity and density) of its constituent phases (minerals, melts and fluids). Information on the fundamental thermodynamic and physical behaviour of phases is subject to constant advance via experimental and ab-initio techniques.
This session aims to provide a holistic view of the formation, dynamics, structure and composition of Earth and the evolution of terrestrial bodies by bringing together studies from geophysics, geodynamics, mineral physics, geochemistry, and petrology. This session welcomes contributions focused on data analysis, modeling and experimental work that address the formation and evolution of terrestrial planets and moons in the Solar System, and around other stars.

Processes controlling the global cycles of volatiles (e.g., C, H, O, S) across reservoirs regulate planetary climate and habitability. Their cycling pathways and efficiency are dependent on numerous factors including the presence of liquid water and the tectonic mode; and involves the atmosphere, hydrosphere, crust, mantle and even the core.
On Earth, major volatile cycles are balanced to first order through ingassing and outgassing, mainly occurring at subduction zones, and major sites of volcanism (i.e., mid-ocean ridges and hotspots), respectively. In planetary interiors, volatiles are partitioned into the existing minerals, or stabilize minor phases such as diamond or various hydrous phases in the mantle and crust, something that directly influences the spatial distribution of melt formation as well as rock properties. Conversely, melt transport induces volatile exchanges between planetary reservoirs and favours outgassing. Outgassing, in turn, will regulate planetary climates, hence influencing the habitability.
The aim of this session is to bring together numerical, experimental and observational expertise from Earth and Planetary Sciences to advance the understanding of interior-atmosphere coupling and volatile exchange and evolution on Earth and terrestrial (exo)planets, as well as the role of those volatiles on the interior composition and dynamics. This session features contributions on topics including volatile cycling, melt and volatile transport, mineral-melt phase relations, geophysical detections, tectonic regimes, outgassing, atmospheric composition and planetary habitability.
Mineralogy is the cornerstone of many disciplines and is used to solve a wide range of questions in geoscience. This broad session offers the opportunity to explore the diversity of methods and approaches used to study minerals and how minerals behave and evolve in their many contexts. We welcome contributions on all aspects of mineralogy, including environmental, soil science, metamorphic, plutonic, deep Earth, planetary, applied mineralogy, and so on. All approaches are welcome: analytical, experimental and theoretical.
Mineral deposits represent principal sources of metallic and non-metallic raw materials for our society. The implementation of new climate policies and the rise of green energy production and use will trigger an unprecedented demand increase for such resources. Formation of economic commodities requires component sequestration from source region, transport and focusing to structural or chemical barriers. These enrichment processes typically involve magmatic, hydrothermal, weathering or metamorphic events, which operate in diverse geodynamic settings and over various time scales. The scope of this session is to collect insights from diverse areas of mineral exploration, field, analytical or experimental studies of mineral deposits as well as resource characterization and extraction. We invite contributions from fields of economic geology, mineralogy and geochemistry in order to advance our understanding of ore-forming systems.

Lithosphere evolution, reflected in the lithosphere structure, controls the deposition of mineral resources, many of which occur in specific geodynamic settings. We invite contributions from various geophysical, geodynamic, geological, and geochemical studies, as well as from numerical modeling, which address the questions how various plate tectonics and mantle dynamics processes modify the lithosphere structure, control ore deposits, and how these processes changed during the Earth's evolution. We particularly invite contributions with focus on regional geophysical studies of the crust and upper mantle.
This session is a part of the International Lithosphere Program Task Force 1. We invite contributions from everyone interested in the topic and invite them to join the ILP TF1.

Minerals are formed in great diversity under Earth surface conditions, as skeletons, microbialites, speleothems, or authigenic cements, and they preserve a wealth of geochemical, biological, mineralogical, and isotopic information, providing valuable archives of past environmental conditions. Interpreting these archives requires fundamental understanding of mineral formation processes, but also insights from the geological record.
In this session we welcome oral and poster presentations from a wide range of research of topics, including process-oriented studies in modern systems, the ancient rock record, experiments, computer simulations, and high-resolution microscopy and spectroscopy techniques. We intend to reach a wide community of researchers sharing the common goal of improving our understanding of the fundamental processes underlying mineral formation, which is essential to read our Earth’s geological archive.

The demand for raw materials and critical raw materials, to supply the needs of both society and industry, is continuously growing, imposing environmental, societal, and technological challenges.
These activities are inevitably accompanied by the production of large volumes of residues, through both exploitation and processing.
In the past, mining activity and extractive waste management were approached, mainly considering the environmental hazards and landscape degradation, but, nowadays, the development of innovative and technological processes, that allow us to reduce, reuse and recycle such industrial residues, as well as more sustainable exploitation practices, give us the opportunities to exploit the huge volumes of past mineral waste as an important source of raw materials.
Residues, such as waste rock, tailings, slags and fly ashes, often hold impressive residual mineral values, and have the potential to be converted to secondary raw materials and mineral resources, for these reasons further challenges are the geochemical, petrographic and mineralogical characterization and the modelization of waste deposits to realistically assess the prospects for sustainable exploitation. It must become the norm to maximize resource use, reduce the volume for final disposal, and also mitigate the risk of environmental damage, associated with the increasing global demand for raw materials and minerals resources.
The main topics to be discussed in this session address, but are not limited to:
- Characterization of geomaterials, their environmental interactions, and decay
- Characterization of industrial residue resources and their environmental assessment
- Secondary raw materials exploitation and valorisation

Reactions between fluids and rocks have a fundamental impact on many of the natural and geo-engineering processes in crustal settings. Examples of such natural processes are localization of deformation, earthquake nucleation caused by high pressure fluid pulses, as well as metamorphic reactions and rheological weakening triggered by fluid flow, metasomatism and fluid-mediated mass transport. Moreover, the efficiency of many geo-engineering processes is partly dependent on fluid-rock interactions, such as hydraulic fracturing, geothermal energy recovery, CO2 storage and wastewater injection. All our observations in the rock record are the end-product of all metamorphic, metasomatic and deformation changes that occurred during the interaction with fluid. Therefore, to investigate and understand these complex and interconnected processes, it is required to merge knowledge and techniques deriving from several disciplines of the geosciences.
We invite multidisciplinary contributions that investigate fluid-rock interactions throughout the entire breadth of the topic, using fieldwork, microstructural and petrographic analyses, geochemistry, experimental rock mechanics, thermodynamic modeling and numerical modeling.

Hydrothermal systems exert crucial influence on volcanic hazards. For example, hydrothermal alteration can reduce the strength of edifice- and dome-forming rocks, increasing the likelihood of volcano spreading and flank collapse, and high pore pressures that develop within hydrothermal systems can promote phreatic/phreatomagmatic explosions and further increase volcano instability. On the other hand, hydrothermal systems also offer the opportunity to exploit minerals of economic interest, and their heat can be harnessed to produce energy. A detailed understanding of hydrothermal systems and their resulting alteration, using multidisciplinary studies, is required to better anticipate the hazards posed, to exploit the economic opportunities they provide, and to execute engineering design. We invite diverse contributions dedicated to the characterisation, imaging, monitoring, and hazard/economic assessment of volcanic hydrothermal systems. Contributions can be based on fieldwork, laboratory work, modelling, or a combination of these approaches. Because understanding hydrothermal systems requires multidisciplinary, collaborative teamwork, we welcome contributions based on any subdiscipline (e.g., geology, geophysics, geochemistry, engineering) and using any technique or method (e.g., geological mapping, magnetic, gravity, and spectroscopic methods, laboratory experiments, gas monitoring, numerical modelling). It goes without saying that we hope to have a diverse session in terms of both speakers and audience.

Fluid flow in the Earth’s crust is driven by pressure gradients and temperature changes induced by internal heat. The expression of crustal fluid flow is associated with a range of structural and geochemical processes taking place in the basement but also in sedimentary covers forming the upper crust. Groundwater, hydrothermal brines and gases circulating in the subsurface interact with local structures across different tectonic and geological settings. Under near-lithostatic conditions fluids and rocks are expelled vertically to the near-surface featuring a variety of surficial geological phenomena ranging from hydrothermal systems to sedimentary and hybrid volcanism and cold seeps both on land and along continental margins. These vertical fluid flow expressions and piercement structures are characterized by complex sedimentary deformation and geochemical reactions where life can adapt to thrive in extremely harsh environments making them ideal windows to the deep biosphere. Several studies have shown that CO2- and CH4-dominaterd (or hybrid) vents played a key role in the evolution of our planet and the cycles of life during several geological eras. Furthermore, the elevated pore pressures often encountered in reservoirs at depth make piercements ideal natural laboratories to capture precursors of seismic events and dynamically triggered geological processes. Yet, the geochemical and geophysical processes associated with the evolution of these vertical fluid flow features and piercements remain poorly understood.
This session welcomes contributions from the community working at the interface between magmatic and sedimentary environments using geophysical, geochemical, microbial, geological, numerical and laboratory studies to promote a better understanding of modern and paleo fluid-driven systems in the upper crust. In particular we call for contributions from: 1) investigations of tectonic discontinuities pre-existing geological structures; 2) the geochemical reactions occurring at depth and at the surface including microbiological studies; 3) geophysical imaging and monitoring of fluid flow systems associated with vertical fluid expulsion at the upper crust; 4) experimental and numerical studies about fluid flow evolution; 5) studies of piercement dynamics related to climatic and environmental implications.
Fluid-mediated rock transformation, also called mineralogical replacement, are ubiquitous instances of fluid-rock interaction in the crust. With recent developments in measurement techniques, the characterization and understanding of replacement has potential to unravel fluid dynamics and migration pathways, the volume of reactive fluids involved, the deformation associated to the reaction, along with the thermodynamical properties of the reaction. The ambition of the proposed session is to draw a picture of the current state of knowledge about the driving processes of fluid-mediated transformation in the diagenetic domain and in the low metamorphic conditions, with or without associated deformation. We welcome any contribution focusing on methodological, experimental, analytical or nature-related studies of mineralogical replacements and associated phenomenon.

Dissolution, precipitation, and chemical reactions between infiltrating fluid and rock matrix alter the composition and structure of the rock, either creating or destroying flow paths. Strong, nonlinear couplings between the chemical reactions at mineral surfaces and fluid motion in the pores often leads to the formation of intricate patterns: networks of caves and sinkholes in karst area, wormholes induced by the acidization of petroleum wells, porous channels created during the ascent of magma through peridotite rocks. Dissolution and precipitation processes are also relevant in many industrial applications: dissolution of carbonate rocks by CO2-saturated water can reduce the efficiency of CO2 sequestration, mineral scaling reduces the effectiveness of heat extraction from thermal reservoirs, acid rain degrades carbonate-stone monuments and building materials.
With the advent of modern experimental techniques, these processes can now be studied at the microscale, with direct visualization of the evolving pore geometry. On the other hand, the increase of computational power and algorithmic improvements now make it possible to simulate laboratory-scale flows while still resolving the flow and transport processes at the pore-scale.
We invite contributions that seek a deeper understanding of reactive flow processes through interdisciplinary work combining experiments or field observations with theoretical or computational modeling. We seek submissions covering a wide range of spatial and temporal scales: from table-top experiments and pore-scale numerical models to the hydrological and geomorphological modelling at the field scale. We also invite contributions from related fields, including the processes involving coupling of the flow with phase transitions (evaporation, sublimation, melting and solidification).

Garnet is probably the most useful mineral to understand the evolution of basement areas on Earth particularly those characterized by high-temperature metamorphism. This mineral allows us to decipher the metamorphic evolution of different rock types by the thermobarometric information stored in the variable chemical composition of zoned garnet. In addition, garnet (1) preserves mineral assemblages formed during prograde metamorphism, (2) can be used to date specific metamorphic events, and (3) forms by partial melting of a rock leading to dense restites. According to recent progress in a better understanding of the characteristics of garnet and their application and modelling to natural rocks, we invite a broad spectrum of geoscientists, including petrologists, geochemists, and structural geologists to present their studies involving garnet to this interdisciplinary symposium. These studies should include experimental aspects as well as case-studies of rocks with emphasis on garnet.
Metamorphic minerals provide unique records of the tectonic processes that have shaped Earth through the ages. Innovative new approaches in metamorphic petrology, chemical and isotope micro-analysis, and geochronology provide exciting new avenues to let these minerals tell their story of deformation, reaction and fluid flow. The insights from such research provide key means of testing long-standing concepts in petrology and tectonics, and shifting paradigms in these fields.
This session will highlight integrated metamorphic petrology, with application to tectonics and development of collisional orogens, cratons and subduction zones. We welcome contributions, from petrology, (petro-)chronology, to trace-element and isotope geochemistry. Through these diverse insights, the session will provide an exciting overview of current research on metamorphic and metasomatic processes, as well as the avenues for future innovation.
The goal of this session is to reconcile short-time/small-scale and long-time/large-scale observations, including geodynamic processes such as subduction, collision, rifting, or mantle lithosphere interactions. Despite the remarkable advances in experimental rock mechanics, the implications of rock-mechanics data for large temporal and spatial scale tectonic processes are still not straightforward, since the latter are strongly controlled by local lithological stratification of the lithosphere, its thermal structure, fluid content, tectonic heritage, metamorphic reactions, and deformation rates.
Mineral reactions have mechanical effects that may result in the development of pressure variations and thus are critical for interpreting microstructural and mineral composition observations. Such effects may fundamentally influence element transport properties and rheological behavior.
Here, we encourage presentations focused on the interplay between metamorphic processes and deformation on all scales, on the rheological behavior of crustal and mantle rocks, and time scales of metamorphic reactions in order to discuss
(1) how and when up to GPa-level differential stress and pressure variations can be built and maintained at geological timescales and modeling of such systems,
(2) deviations from lithostatic pressure during metamorphism: fact or fiction?
(3) the impact of deviations from lithostatic pressure on geodynamic reconstructions.
(4) the effect of porous fluid and partial melting on the long-term strength.
We, therefore, invite the researchers from different domains (rock mechanics, petrographic observations, geodynamic and thermo-mechanical modeling) to share their views on the way forward for improving our knowledge of the long-term rheology and chemo-thermo-mechanical behavior of the lithosphere and mantle.
The timescale of magma formation, storage and ascent beneath active volcanoes is crucial to constrain the magma chamber dynamics and provide the basis for volcanic hazard assessment. The interpretation of rock textures is the key step of the back-analysis studies targeted at the reconstruction of the magma chamber dynamics and depends on our understandings of the crystallization kinetic processes in silicate melts. Beside crystal formation, dissolution and reaction of pre-existing crystals, are processes that commonly affect the kinetics of magma crystallization and that, however, are broadly constrained from the theoretical and the experimental point of view.
Experimental studies can shed a light on subterranean processes generating eruptions, constraining pre- and syn-eruptive physical and chemical key magmatic variables such as pressure, temperature, volatile and crystal content, melt composition and viscosity. A major goal of modern experimental studies is to constrain the physical and chemical parameters of deep magmatic reservoirs, such as those located at Moho-lower crust boundary.
This session invites contributions dealing with the nucleation and growth of minerals, the “fate of pre-existing crystals”, the effects of crystallization kinetics on mineral chemistry as well as the partitioning of trace elements between crystals and melts during high-pressure differentiation and storage of magmas. We particularly encourage submissions on experimental petrology, thermodynamic and geochemical modelling, as well as on field studies.

Volcanic settings host a variety of complex and interconnected processes that can significantly control their eruptive behaviour. Magmas can reside at a certain depth in the crust for a relatively long time and erupt almost instantaneously. During the time spent at depth, magmas can evolve via fractional crystallization, mingle and mix with new magmas of deeper origin and interact with the wall rocks, whereas during ascent, decompression typically triggers degassing and crystallization. Both magma chamber and conduit processes play a pivotal role in controlling the geochemical and physical properties of magmas that strongly affect the frequency and style of eruption. As investigation of such processes cannot be performed via direct observations, we analyse the texture and composition of the erupted products to acquire information about magma evolutionary processes and conduit dynamics using a variety of techniques. In addition, we can design experimental setups and numerical simulations aimed at reproducing the natural conditions of magma storage and ascent. In this session we welcome contributions that provide insights into volcanic and igneous plumbing systems (VIPS) dynamics using petrology, volcanology, thermodynamics and modelling tools. We particularly welcome studies that integrate different approaches to unravel magmatic processes and timescales that lead to eruption.

The Fagradalsfjall eruption on the Reykjanes Peninsula of Iceland started on 19 March 2021. It provides a unique opportunity to study all aspects of a low-intensity effusive basaltic eruption in great detail using multidisciplinary approaches. The Fagradalsfjall eruption followed a several-week long period of intense seismicity and deformation associated with formation of the feeding dike. The eruption terminated on September 18, 2021, after producing a lava field covering about 4.5 km2. The eruption progressed through several phases, each characterized by different emission sources, eruptive style, intensities, and associated hazards. The eruption may be representative of the formation of a shield volcano, a process that the scientific community has had limited chances to observe in real time.
We welcome submissions on sustained low-intensity basaltic eruptions including (but not limited to) the 2021 Fagradalsfjall eruption; their plumbling systems, eruptive products, and impacts. We particularly encourage comparative studies across different regions that may help us to better understand the volcanic processes that are active in the Fagradalsfjall eruption.
Topics may include, for example: physical volcanology of eruptive products and eruptive behavior; lava flow modeling; acoustic studies; petrology; geochemistry and interaction with groundwater; studies of volcanic gases; crustal deformation; seismology; volcano monitoring; social effects; health effects; hazard mitigation; tectonic implications; volcano-tectonic interactions; atmosphere-climate interactions, etc.

This session is devoted to the most recent eruption of the Cumbre Vieja volcano, which started on Sept. 19, 2021, on the island of La Palma after 50 years of repose. Volcanic unrest was recorded in Oct. 2017, when a seismic swarm was located at more than 20 km depths. Nine additional swarms followed, the last one was recorded in June 2021. Geochemical anomalies followed this increased seismicity indicating a magmatic recharge at depth. On Sept. 11, 2021, a new seismic swarm was observed at shallower depths (10-12 km), indicating a possible magmatic intrusion. This was confirmed when geodetic monitoring networks on the island started showing clear signs of inflation. The seismicity increased in frequency and intensity with many felt earthquakes. Seismic activity accelerated in the morning of Sept. 19 when a strong shallow earthquake was widely felt on the western part of the island. This was the precursor of the eruption, which started at about 14:10 UTC on the same day. A series of vents opened along a fissure close to Los Llanos on the western flank of Cumbre Vieja volcano. The eruption displayed vigorous lava fountaining and powerful Strombolian explosions while lava effusion produced a compound Aa flow field. The eruption has destroyed hundreds of buildings, plantations as well as cutting vital transport routes.
This session is open to contributions aimed at geological, geophysical, geochemical and volcanological studies of the eruption and its precursors and, more in general, to studies that can help better understanding the eruptive dynamics. We also welcome contributions focused on the management of scientific communication during this crisis and the management of the volcanic emergency.

Glaciers and volcanoes interact in a number of ways, including instances where volcanic/geothermal activity alters glacier dynamics or mass balance, via subglacial eruptions or the deposition of supraglacial tephra. Glaciers can also impact volcanism, for example by directly influencing mechanisms of individual eruptions resulting in the construction of distinct edifices. Glaciers may also influence patterns of eruptive activity when mass balance changes adjust the load on volcanic systems, the water resources and hydrothermal systems. However, because of the remoteness of many glacio-volcanic environments, these interactions remain poorly understood.
In these complex settings, hazards associated with glacier-volcano interaction can vary from lava flows to volcanic ash, lahars, landslides, pyroclastic flows or glacial outburst floods. These can happen consecutively or simultaneously and affect not only the earth, but also glaciers, rivers and the atmosphere. As accumulating, melting, ripping or drifting glaciers generate signals as well as degassing, inflating/ deflating or erupting volcanoes, the challenge is to study, understand and ultimately discriminate these potentially coexisting signals. We wish to fully include geophysical observations of current and recent events with geological observations and interpretations of deposits of past events. Glaciovolcanoes also often preserve a unique record of the glacial or non-glacial eruptive environment that is capable of significantly advancing our knowledge of how Earth's climate system evolves.
We invite contributions that deal with the mitigation of the hazards associated with ice-covered volcanoes in the Arctic, Antarctic or globally, that improve the understanding of signals generated by ice-covered volcanoes, or studies focused on volcanic impacts on glaciers and vice versa. Research on recent activity is especially welcomed. This includes geological observations e.g. of deposits in the field or remote-sensing data, together with experimental and modelling approaches. We also invite contributions from any part of the world on past activity, glaciovolcanic deposits and studies that address climate and environmental change through glaciovolcanic studies. We aim to bring together scientists from volcanology, glaciology, seismology, geodesy, hydrology, geomorphology and atmospheric science in order to enable a broad discussion and interaction.

The session deals with the documentation and modelling of the tectonic, deformation and geodetic features of any type of volcanic area, on Earth and in the Solar System. The focus is on advancing our understanding on any type of deformation of active and non-active volcanoes, on the associated behaviours, and the implications for hazards. We welcome contributions based on results from fieldwork, remote-sensing studies, geodetic and geophysical measurements, analytical, analogue and numerical simulations, and laboratory studies of volcanic rocks.
Studies may be focused at the regional scale, investigating the tectonic setting responsible for and controlling volcanic activity, both along divergent and convergent plate boundaries, as well in intraplate settings. At a more local scale, all types of surface deformation in volcanic areas are of interest, such as elastic inflation and deflation, or anelastic processes, including caldera and flank collapses. Deeper, sub-volcanic deformation studies, concerning the emplacement of intrusions, as sills, dikes and laccoliths, are most welcome.
We also particularly welcome geophysical data aimed at understanding magmatic processes during volcano unrest. These include geodetic studies obtained mainly through GPS and InSAR, as well as at their modelling to imagine sources.
The session includes, but is not restricted to, the following topics:
volcanism and regional tectonics;
formation of magma chambers, laccoliths, and other intrusions;
dyke and sill propagation, emplacement, and arrest;
earthquakes and eruptions;
caldera collapse, resurgence, and unrest;
flank collapse;
volcano deformation monitoring;
volcano deformation and hazard mitigation;
volcano unrest;
mechanical properties of rocks in volcanic areas.
Over the past few years, major technological advances significantly increased both the spatial coverage and frequency bandwidth of multi-disciplinary observations at active volcanoes. Networks of instruments, both ground- and satellite-based, now allow for the quantitative measurement of geophysical responses, geological features and geochemical emissions, permitting an unprecedented, multi-parameter vision of the surface manifestations of mass transport beneath volcanoes. Furthermore, new models and processing techniques have led to innovative paradigms for inverting observational data to image the structures and interpret the dynamics of volcanoes. In particular, machine learning, a type of AI in which computers learn from data, is gaining importance in volcanology, not only for monitoring purposes (i.e., in real-time) but also for later hazards analysis (e.g. modelling tools).
Within this context, this session aims to bring together a multidisciplinary audience to discuss the most recent innovations in volcano imaging and monitoring, and to present observations, methods and models that increase our understanding of volcanic processes.
We welcome contributions (1) related to methodological and instrumental advances in geophysical, geological and geochemical imaging of volcanoes, (2) to explore new knowledge provided by these studies on the internal structure and physical processes of volcanic systems, and (3) to investigate the potential of machine learning techniques to process multispectral satellite data for developing a better understanding of volcanic hazards.
We invite contributors from all geophysical, geological and geochemical disciplines: seismology, electromagnetics, geoelectrics, gravimetry, magnetics, muon tomography, volatile measurements and analysis. The session will include in-situ monitoring and high- resolution remote sensing studies that resolve volcanic systems ranging from near-surface hydrothermal activity to deep magma migration.

The impact of magma-sediment interactions in the top wet sediments of active sedimentary basins is poorly quantified. Yet this accelerator of diagenetic processes, impacts important fields of geology ranging from potential ocean-climate disorder due to petroleum mobilization and emission, to catabolic power supply for deep microbial activity. With one end-member killing life and the other fueling it, can we derive the implications at the scale of the plate cycle? This session calls for contributions that help to understand the magma-sediment interaction processes in the first 500 m of active sedimentary basins and how it may play a major role the Earth CPL-Cycles (Carbon-, Plate-, Life-Cycles).
Volcanoes are inherently complex and dynamic geological system, acting as the source of diverse sediment types and as a control on varied sediment transport processes within surrounding environments, both during and after their life. This can manifest as an accumulation of thick primary volcaniclastic sequences from pyroclastic (e.g. pyroclastic density currents, tephra falls), laharic and flank instability processes, secondary volcaniclastic sequences from the reworking/redeposition (or both) of primary deposits and their interaction with non-volcanic sedimentary processes, or deposits from the weathering of lava flows. The diversity of processes that may be involved in the generation of volcaniclastic sequences makes often difficult to describe and interpret them. As the comprehension of the generation, transportation and accumulation mechanisms of volcaniclastic sequences is of extreme importance for natural hazard and economic perspectives, to reduce uncertainties and move forward in the identification of volcano-sedimentary processes and potential effects, modern and ancient volcaniclastic sequences must be studied and interpreted hand in hand. Thus, the proposed session aims to bring together studies that explore the volcaniclastic record of modern and ancient environments. Contributions are welcomed in areas including, but not limited to, the identification of volcanic features in ancient sedimentary records, multidisciplinary (e.g., stratigraphic, petrographic, geophysical) approaches to the study of modern subaerial and submarine volcaniclastic sequences as analogue sites, and examples of the modification of sedimentary systems across syn- and inter-eruptive periods.

Volcanoes play an essential role in society through their impacts on human
life, infrastructure, and the environment. Those in marine settings pose
hazards, such as the awakening of submarine volcanoes, underwater
explosions, and sudden release of harmful gases from the volcano or
overlying water column, and tsunami inundation of neighboring coastlines
due to caldera collapse, submarine landslides, or entry of pyroclastic
flows into the sea. Specifically, volcanic degassing plays a dominant role
in forcing the timing and nature of volcanic unrest and eruptions in such
settings. On the other hand, quiescent passive degassing and
smaller-magnitude eruptions can impact the regional climate system. For
those reasons understanding the exsolution processes of gas species
dissolved in magma and measuring their emissions is crucial to
characterize the eruptive mechanism and evaluate the subsequent impacts on
the atmospheric composition, the environment, and the biosphere.
The session will be focused on multidisciplinary monitoring volcanic
environments, including in the vicinity of cities and highly touristic areas. Since
gas emissions are measured and monitored via in-situ and remote sensing
techniques, we invite contributions to studies that gain insights into the
subterranean-surface processes and quantify their impacts. In addition, we
encourage studies that focus on modelling the subsurface and
atmospheric/climatic processes and laboratory experiments that are
fundamental to the interpretation of field-based and satellite
observations. Finally, we will undoubtedly discuss the ability to
recognize the hazards and their impact on people, emergency management by
civil protection authorities, community education, case studies and risk
mitigation to reduce the effects of volcanism and its societal impact.

Developing physical-mathematical models able to describe the evolution of eruptive phenomena is a key point in volcanology. In the case of high-risk phenomena, such as lava flows or ash dispersal, predicting their spatial and temporal evolution and determining the potentially affected areas is fundamental in supporting every action directed at mitigating the risk as well as for environmental planning.
This session aims to address unresolved challenging questions related to complex geophysical flow modeling and simulation, gathering physical-mathematical models, numerical methods and field and satellite data analysis in order to: (i) expand knowledge of complex volcanic processes and their space-time dynamics; (ii) monitor and model volcanic phenomena; (iii) evaluate model robustness through validation against real case studies, analytical solutions and laboratory experiments; (iv) quantify the uncertainty propagation through both forward (sensitivity analyses) and inverse (optimization/calibration) modelling in all components of volcanic hazard modelling in response to eruptive crises.
Volcanic islands are simultaneously some of the tallest and fastest-forming geological features on Earth and constitute the site of significant geohazards ranging from volcanic eruptions, earthquakes, landslides, and tsunamis. Ocean island volcanoes are also some of the most enigmatic features in our planet, as their genesis is still not satisfactorily explained by conventional plate tectonics. The scientific community faces several challenges in studying volcanic islands, particularly in what regards processes taking place at depth. There is still a need to densify seismic networks in volcanic islands, using both land- and seafloor-based stations, to record the signals associated with volcanic and tectonic processes and automatically or manually detect and classify those signals. 3D images from the shallow crust to the deep mantle are crucial to unravel the geodynamic processes behind the generation of volcanism. More accurate quantification of temporal changes in the volcanic systems will help in the forecasting of potential eruptions and the monitoring of existing ones. On top of that, the presence of geothermal systems and induced seismicity from industrial exploration are also critical challenges in volcanic islands due to the system's complexity.
Considering the enormous diversity of interactions in volcanic islands, we welcome contributions from a wide range of studies including: seismo-volcanic monitoring and tracking of magma movements; characterization and location of volcanic tremor; 3D and 4D seismic imaging, including attenuation tomography; seismic ambient noise monitoring; machine learning to detect and classify volcanic earthquakes; active source studies to characterize volcanic flanks and landslides; induced and triggered seismicity in geothermal systems; and seismic sources.

The Phanerozoic has been punctuated by five mass extinctions and several major environmental perturbations, which were contemporaneous with massive volcanism and meteorite impacts. The session aims to gather researchers from geological, geophysical, and biological disciplines to highlight the recent advances of the causes and consequences of these environmental events. Therefore, contributions dealing with all aspects of the end-Ordovician, end-Devonian, end-Permian, end-Triassic, end-Cretaceous) and other related paleoenvironmental crises (e.g. the Paleocene-Eocene Thermal Maximum (PETM) and Oceanic Anoxic Events (OEAs) in the Mesozoic are welcome.

The 2021-2022 Hunga Tonga-Hunga Ha'apai eruption in Tonga was among the largest of recent decades. The event was notable for its high intensity, generating a convective column that rapidly ascended well into the stratosphere; for the atmospheric pressure wave generated by the explosion, which was detected globally; and for generating a tsunami that was observable across Pacific Ocean shorelines. Following a series of preceding seismic and explosive events since December 2021, the sustained phase of the eruption on 15th January was relatively short lived, but the associated pressure wave and tsunami impacts were the most far-reaching since the eruption of Krakatau volcano in 1883. Tsunamis were recorded both locally and in the far-field, but their mechanism(s) remains uncertain; in the near field being from either (or both of) the collapsing eruption column or a phreatomagmatic explosion as the erupting mass mixed with sea water. In the far-field the tsunamis are possibly best explained by the massive atmospheric pressure wave, that is the first instrumentally recorded eruption-generated event of its type, which affected the entire global atmosphere and ionosphere, causing the observed infrasound waves and unusual long-period seismic resonances.
This interdisciplinary late-breaking session welcomes contributions from all disciplines involved in local and global observations of this eruption and its effects, including remote sensing observations and modeling as well as hazard assessment and estimation of damage and long-term consequences.
The North-Atlantic-Arctic realm hosts vast extended continental shelves bordering old land masses, two Large Igneous Provinces (LIPs), one of which is the largest known sub-marine LIP (Alpha-Mendeleev Ridge) and a complex ocean spreading systems, including the slowest mid-ocean spreading ridge (Gakkel Ridge) and several extinct ocean basins.
Over recent decades, increasing scientific interest has led to the acquisition of vast quantities of geological and geophysical data across the North Atlantic-Arctic realm, yet our understanding of the region has become, if anything, even more controversial than it was before. The geodynamic and geomorphological processes acting here (and globally) are key to the understanding of the structure, geodynamic and paleolandscape evolution, hazards and resources in the region.
This session provides a forum for discussions and reviews of a variety of problems linked to the North Atlanitc-Arctic geodynamics such as plate tectonic, geodynamic, compositional, thermal, structural and landscape models, configuration of sedimentary basin and to propose additional experiments that can test these models. We welcome contributions from all relevant disciplines, including, but not limited to, plate tectonics, geophysics, geodynamic modelling, igneous, metamorphic and structural geology, palaeomagnetism, sedimentology, geomorphology, geochronology, thermochronology, geochemistry and petrology.

The Tethyan orogenic belt is one of the largest and most prominent collisional zones on Earth. The belt ranges from the Mediterranean in the west to Papua New Guinea in the east. It results from the subduction and closure of multiple basins of the Tethys Ocean and the subsequent collision of the African, Arabian and Indian continental plates with Eurasia. Its long-lasting geological record of the opening and closure of oceanic basins, the accretion of arcs and microcontinents, the complex interactions of major and smaller plates, and the presence of subduction zones at different evolutionary stages, has progressively grown as a comprehensive test site to investigate fundamental plate tectonics and geodynamic processes with multiple disciplines. Advances in a variety of fields provide a rich and growing set of constraints on the crust-lithosphere and mantle structure and their physical and chemical characteristics, as well as the tectonics and geodynamic evolution of the Tethyan orogenic belt.
We welcome contributions presenting new insights and observations derived from different perspectives, including geology (tectonics, stratigraphy, petrology, geochronology, geochemistry, and geomorphology), geophysics (seismicity, seismic imaging, seismic anisotropy, gravity), geodesy (GPS, InSAR), modelling (numerical and analogue), natural hazards (earthquakes, volcanism). In particular, we encourage the submission of trans-disciplinary studies, which integrate observations across a range of spatial and temporal scales to further our understanding of plate tectonics as a planetary process of fundamental importance.
The Arabian Plate recorded several plate reorganizations from the Neoproterozoic to present, including the Cadomian and Angudan orogenies, Late Paleozoic rifting and Alpine Orogeny. Active tectonics are framing the Arabian Plate and produce a variety of structures, including extensional structures related to rifting of the Red Sea and Gulf and Aden, strike-slip structures at the Dead Sea and Owen transform faults and compressive structures related to the Zagros-Makran convergence zone. The Arabian Peninsula contains the planet’s largest hydrocarbon reservoirs, owing to its geological history as Gondwana’s passive margin during the Permo-Mesozoic. Moreover, the Semail Ophiolite as the largest exposed ophiolite on Earth offers a unique example of large-scale obduction and overridden sedimentary basins. This and the spectacular outcrop conditions make the Arabian Peninsula an important and versatile study area. Ongoing research and new methods shed new light on, e.g., mountain building processes and its geomorphological expression as well as hydrocarbon development/migration.
We invite contributions that utilize structural, geophysical, tectonic, geochronological, geomorphological, sedimentary, geochemical/mineralogical, and field geological studies from the Arabian Peninsula and surrounding mountain belts and basins. These studies may include topics dealing with structures/basin analyses of any scale and from all tectonic settings ranging from the Neoproterozoic until today.
We invite contributions that address the present and past structure and dynamics of the Alpine orogens of the Mediterranean area. Since 2015, the international AlpArray mission and related projects have generated a plethora of new data to test the hypothesis that mantle circulation driving plates’ re-organization during collision has both immediate and long-lasting effects on the structure, motion, earthquake distribution and landscape evolution in mountain belts. Links between Earth’s surface and mantle have been forged by integrating 3D geophysical imaging of the entire crust-mantle system, with geologic observations and modelling to provide a look both backwards and forwards in time, the 4th dimension. This integrated 4D approach, initially focused on the Alps, has been expanded to the Pannonian-Carpathian and Adriatic areas, and now includes the Apennines and Dinarides. A new initiative, AdriaArray, is underway to shed light on plate-scale deformation and orogenic processes in this dynamic part of the Alpine-Mediterranean chain. The forthcoming Drilling the Ivrea-Verbano zonE (DIVE) project bridges new observations across scales and investigates the evolution of the continental lower crust. This session provides an interdisciplinary platform for highlighting the newest results and open questions of the aforementioned projects, regions and themes.

Scientific drilling through the International Ocean Discovery Program (IODP) and the International Continental Scientific Drilling Program (ICDP) continues to provide unique opportunities to investigate the workings of the interior of our planet, Earth’s cycles, natural hazards and the distribution of subsurface microbial life. The past and current scientific drilling programs have brought major advances in many multidisciplinary fields of socio-economic relevance, such as climate and ecosystem evolution, palaeoceanography, the deep biosphere, deep crustal and tectonic processes, geodynamics and geohazards. This session invites contributions that present and/or review recent scientific results from deep Earth sampling and monitoring through ocean and continental drilling projects. Furthermore, we encourage contributions that outline perspectives and visions for future drilling projects, in particular projects using a multi-platform approach.

Metallurgical slags are generated as a by-product of smelting during ironmaking, steelmaking, and the production of ferroalloys and non-ferrous metals. The formation conditions result in complex (geo)chemical and mineralogical characteristics unique to slags alone. Historically slags have been discarded as a waste product and, through release of potentially toxic trace elements, represent a hazard to the environment and human health. However, increasingly we are realizing the resource potential of what was previously thought of as waste, thus reducing the environmental impact and taking a step closer to a circular economy.
The aim of this short course is to is to give an overview on the environmental geochemistry and resource potential of metallurgical slags by summarizing processes for the generation of slags, describing their chemical and mineralogical characteristics, outlining the fundamental geochemistry that propels slag weathering, and illustrating the utilization of slags and resource recovery of valuable metals from slags. This short course is a follow up of a book entitled “Metallurgical Slags: Environmental geochemistry and Resource Potential” published in 2021 by the Royal Society of Chemistry and gives an overview useful for the environmental geochemists, geologists, mining and civil engineers, waste and resource managers, and all those interested and inspired by a circular economy and minimizing our environmental footprint on planet Earth.
List of presentations:
1. Presentation of the book: Metallurgical Slags: Environmental Geochemistry and Resource Potential (Vojtěch Ettler and Nadine Piatak)
2. Metallurgical overview and production of slags (Elias Matinde, MINTEK, South Africa)
3. Geochemistry and mineralogy of slags (Nadine Piatak, USGS, USA)
4. Weathering of slags (Jakub Kierczak, University of Wroclaw, Poland)
5. Leaching properties and environmental fate of slags (Vojtech Ettler, Charles University, Czech Republic)
6. Environmental applications of slag (Helena Gomes, University of Nottingham, UK)
7. Metal recovery from slags (Anna Potysz, University of Wroclaw, Poland)
8. Discussion and course closure
After the PhD, a new challenge begins: finding a position where you can continue your research or a
job outside academia where you can apply your advanced skills. This task is not
always easy, and frequently a general overview of the available positions is missing. Furthermore,
in some divisions, up to 70% of PhD graduates will go into work outside of academia. There are many
different careers which require or benefit from a research background. But often, students and
early career scientists struggle to make the transition due to reduced support and networking.
In this panel discussion, scientists with a range of backgrounds give their advice on where to find
jobs, how to transition between academia and industry and what are the pros and cons of a career
inside and outside of academia.
In the final section of the short course, a Q+A will provide the audience with a chance to ask
their questions to the panel. This panel discussion is aimed at early career scientists but anyone
with an interest in a change of career will find it useful. An extension of this short course will
run in the networking and early career scientist lounge, for further in-depth or
one-on-one questions with panel members.

The science-policy interface is not just as a way to increase the impact of our science, but it is also a scientific subject in itself. It presents several challenges to both scientists and policy-makers. They include understanding the different steps in the policy cycle: from setting the agenda to formulating, adopting, implementing, monitoring and evaluating polices. It is also crucial to know which facts and evidences are most needed at each step, so scientists can provide the best information at the right time and in the best way.
This session provides the opportunity for discussing with policy makers and addressing the necessary skills to facilitate the uptake of hydrological sciences in policy formulation and implementation.
This session will host invited-talks only and an interactive online/onsite panel discussion with the audience.

Liaising with stakeholders, policy-makers and society is becoming increasingly important for academic research to turn research into impactful action, but also to improve research by allowing society to take part within research processes in terms of co-producing knowledge and policy. In hydrological sciences, this is needed when implementing innovative solutions in areas such as river basin management, water allocation, impact-based hydrological forecasting, flood protection, drought risk management, climate change mitigation, ecohydrology and sustainable environmental solutions, among others.
Contributions focus on:
1. Science-policy interface in hydrology. How science influences policy and policies impact science? How scientists can provide easily digestible pieces of evidence to policy-makers? What are the key gaps in joining science to feasible policy solutions in the water sector? How can we use knowledge to improve policy, and vice-versa? How do we deal with uncertainty, adaptation, path dependencies but also with aspects of power, inequality and vested interests in the co-production of knowledge and policy?
2. Interdisciplinary collaborations. How do we create the interdisciplinary knowledge needed to address the questions faced by decision-makers and societal stakeholders? How have new, interdisciplinary, science questions been generated in response to existing and emerging research problems? How can individual disciplinary perspectives come together in interdisciplinary studies and experiments?
3. Hydrology as practiced within society. Who are the users of our knowledge, how useful is our knowledge for those societal users, how useful are our tools, models and methods? What approaches are available to support a fruitful collaboration between hydrological science and practitioners? And, since scientists are not removed from the things they study, how has hydrological science been shaped by the historical interplay of cultural, political and economic factors? What are the opportunities and challenges that this science/society nexus creates for producing scientific knowledge?
4. Understanding of complex human-water systems and their management: what are the feedback mechanisms of emergent phenomena in human-water systems? What are the benefits and shortcomings based on empirical, conceptual or model-based research and disciplinary perspective? How can we enable stakeholders to avoid unintended consequences of water management decisions?
This session welcomes abstracts that consider how to observe, model and analyse interactions of people and water, and the effects of social and environmental changes on hydrological systems. It is organised as part of the IAHS Panta Rhei hydrological decade 2013-2022; and focuses on gains in our understanding of dynamic human-water systems.
Examples of relevant areas include:
- Observations of human impacts on, and responses to, hydrological change.
- Interactions of communities with local water resources.
- Hydrological models that include anthropogenic effects.
- Creation of databases describing hydrology in human-impacted systems.
- Data analysis and comparisons of human-water systems around the globe and especially in developing and emerging countries.
- Human interactions with hydrological extremes, i.e. floods and droughts, and water scarcity.
- The role of gender, age, and cultural background in the impacts of hydrological extremes (floods and droughts), risk perception, and during/after crises and emergencies.
- innovative modelling for exploring the interplay, feedback, and interactions between hydrological extremes and public and private adaptation actions;
- integration of models and observations for advancing knowledge on the human-water systems;
- new frameworks to support risk-based decision-making in case of multi-hazards;

Groundwater, the hidden component of the water cycle, traditionally receives less attention than surface water from both the scientific community and policy makers, due to it being "out of sight, out of mind". However, this precious resource is inextricably linked to the maintenance of natural ecosystems and human well-being. Groundwater has always been part of the lives of worldwide communities: irrigated agriculture is primarily sustained by groundwater resources, particularly in arid and semi-arid regions; holy wells and sacred springs are part of our global cultural heritage, while disagreement over groundwater resources have previously resulted in turmoil and national/transboundary conflicts. These obvious interconnections, however, are neglected in favour of the development of sectorial approaches to groundwater resource assessment.
Socio-hydrogeology has recently been proposed as an effective approach to addressing complex groundwater-related issues in an increasingly holistic and integrated manner. By focusing on the reciprocity between humans and groundwater, it aims to explore and understand their dynamic interactions and feedbacks with a final goal of developing transdisciplinary solutions for transdisciplinary problems. Due to the more "personal" (i.e., individual household/community supplies) and local nature of groundwater in many instances, socio-hydrogeology seeks to understand individuals and communities as a primary source, pathway and receptor for potable groundwater supplies, including the role of local knowledge, beliefs, risk perception, tradition/history, and consumption. In essence, the “socio” in socio-hydrogeology embodies sociology, including social, cognitive, behavioural and socio-epidemiological science.
For this session we encourage contributions from diverse fields, including:
• Examples of socio-hydrogeological assessments (e.g., participatory monitoring, stakeholder engagement, public participation, citizen science)
• Integration of “non-expert” knowledge and experience within quantitative and qualitative hydrogeological studies
• Challenges and opportunities arising from the integration of hydrogeology and social sciences
• Social and political approaches to water resources research
• Groundwater geoethics and national/transboundary conflicts
• Attempts to integrate behavioural, experiential or knowledge-based data with hydrogeological/health risk assessment models
• Educational goals for future socio-hydrogeologists

Water is our planet’s most vital resource, and the primary agent in some of the biggest hazards facing society and nature. Recent extreme heat and flood events are clear demonstrations of how our planet’s climate is changing, underlining the significance of water both as a threat and as an increasingly volatile resource.
The accurate and timely measurement of streamflow is therefore more critical than ever to enable the management of water for ecology, for people and industry, for flood risk management and for understanding changes to the hydrological regime. Despite this, effective monitoring networks remain scarce, under-resourced, and often under threat on a global scale. Even where they exist, observational networks are increasingly inadequate when faced with extreme conditions, and lack the precision and spatial coverage to fully represent crucial aspects of the hydrological cycle.
This session aims to tackle this problem by inviting presentations that demonstrate new and improved methods and approaches to streamflow monitoring, including:
1) Innovative methodologies for measuring/modelling/estimating river stream flows;
2) Real-time acquisition of hydrological variables;
3) Remote sensing and earth observation techniques for hydrological & morphological monitoring;
4) Measurement in extreme conditions associated with the changing climate;
5) Measurement of sudden-onset extreme flows associated with catastrophic events;
6) Strategies to quantify and describe hydro-morphological evolution of rivers;
7) New methods to cope with data-scarce environments;
8) Inter-comparison of innovative & classical models and approaches;
9) Evolution and refinement of existing methods;
10) Guidelines and standards for hydro-morphological streamflow monitoring;
11) Quantification of uncertainties;
12) Development of expert networks to advance methods.
Contributions are welcome with an emphasis on innovation, efficiency, operator safety, and meeting the growing challenges associated with the changing climate, and with natural and anthropogenically driven disasters such as dam failures and flash floods.
Additionally, presentations will be welcomed which explore options for greater collaboration in advancing riverflow methods and which link innovative research to operational monitoring.

Many papers have advised on carefully considering the methods we choose for our modelling studies as they potentially affect our modelling results and conclusions. However, there is no common and consistently updated rulebook on what good modelling practice is and how it has evolved since e.g. Klemes (1986), Refsgaard & Henriksen (2004) or Jakeman et al. (2006). In recent years several papers have proposed useful practices such as benchmarking (e.g. Seibert et al., 2018), controlled model comparison (e.g. Clark et al., 2011), careful selection of calibration periods (e.g. Motavita et al., 2019) and methods (e.g. Fowler et al., 2018 ), or testing the impact of subjective modelling decisions along the modelling chain (Melsen et al., 2019). However, none of the proposed methods have become quite as common and indispensable as the split sample test (KlemeŠ, 1986), despite their very justified existence.
This session hopes to provide a platform for a visible and ongoing discussion on what ought to be the current standard for an appropriate modelling protocol to acquire robust and reliable results considering uncertainty in all its facets. We aim to bring together, highlight and foster work that applies, develops, or evaluates procedures for a robust modelling workflow or that investigates good modelling practices. We invite research that aims to improve the scientific basis of the entire modelling chain and puts good modelling practice in focus again. This might include (but is not limited to) contributions on:
(1) Benchmarking model results
(2) Developing robust calibration and evaluation frameworks
(3) Going beyond common metrics in assessing model performance and realism
(4) Conducting controlled model comparison studies
(5) Developing modelling protocols
(6) Investigating subjectivity along the modelling chain
(7) Uncertainty propagation along the modelling chain
(8) Communicating model results and their uncertainty to end users of model results
(9) Evaluating implications of model limitations and identifying priorities for future model development and data acquisition planning

Eric Wood passed away November 3, 2021. His career spanned five decades. It included early work in systems analysis applications to hydrology dating to his dissertation research at MIT in the 1970s, scaling in the 1980s and 1990s, hydrologic remote sensing beginning with planning for NASA’s Earth Observing System in the 1980s and 1990s, continental hydrology beginning in the 1990s, and hyper-resolution land surface modeling in the mid-2000s, with a "call upon the international hydrologic community and the hydrological science support infrastructure to endorse the effort" and face this "grand challenge" [1]. A hallmark of Eric's career was strong international collaborations, especially with European scientists, notably with his most recent contribution to the development of the End-to-end Demonstrator for improved decision-making in the water sector in Europe (EDgE) for the Copernicus Climate Change Service [2]. Eric Wood attended almost all previous EGU meetings (most recently, the GA in 2019), and was awarded the 2007 John Dalton Medal of the Hydrological Sciences division, and the Union's 2014 Alfred Wegener Medal & Honorary Membership. This session will review Eric's main contributions to hydrology, from data to models, highlighting the experience of former students, postdocs, and colleagues that his life touched.

Water is a strategic issue in the African and Mediterranean regions, mainly because of the scarcity of the available resources in quantity and/or quality. The Mediterranean and African climates and the surface hydrology are characterized by a strong variability in time and space and the importance of extreme events droughts and floods. During the last century, changes of all kinds and intensities, including in the agricultural sector have affected surface and underground reservoirs and water uses. Global and regional hydrological models have recently seen tremendous advances in improved representations of physical processes underpinning these impacts, resulting in better reproductions of observed variables such as streamflow and water extent. As a result, they are increasingly used for predicting socio-economic risks of floods, droughts and water stress in regions around the globe. However, the use of hydroclimatic models for disaster risk reductions in data-sparse regions, while gradually improving, is still limited in comparison.
This session intends to identify and analyse the changes in the Mediterranean and Africa hydrology, in terms of processes, climate and other water-related topics, including environmental and food security. It will gather specialists in observation and modelling of the various water fluxes and redistribution processes within the catchments. Case studies showcasing practical experiments and innovative solutions in decision making under large uncertainty are ncouraged. Contributions addressing the following topics are welcome:
• Spectacular case studies of rapid changes in water resources;
• Using various sources of information for comparing past and present conditions;
• Differentiating climatic and anthropogenic drivers (including GCM reanalysis);
• Modelling hydrological changes (in surface and/or ground water);
• Impacts of extreme events on water systems.

Forests are recognized as prime regulators of the hydrological cycle. Changes in their structure cause effects on the ecosystem services they provide via their water and biochemical cycles. The traditional idea that forest hydrology emphasizes the role of forests and forest management practices on runoff generation and water quality has been broadened in light of rapid global change. Some of the largest pristine forested areas are in the tropics and have suffered drastic land-use changes during recent decades. These tropical systems are still markedly underrepresented in hydrological studies, especially concerning long-term experimental setups and monitoring networks.
Anthropogenic intervention is exerting ever-increasing pressure on natural ecosystems, affecting water quantity and quality, and threatening socio-economic and human development as described by the UN Sustainable Development Goals. Yet, we lack a proper understanding of how catchments respond to changing environmental conditions and disturbances. Answering these open questions requires interdisciplinary approaches in combination with novel monitoring methods and modelling efforts. This session brings together studies that will enhance our understanding and stimulate discussions on the impact of global change on hydrological processes in forest systems at different scales.
We invite field experimentalists and modellers to submit contributions investigating hydrological processes in forests from boreal to tropical regions, including water quality, the carbon cycle, or ecohydrological aspects.
This session welcomes studies that:
1) Improve our understanding of hydrological processes in forested catchments and the resilience of forested catchments to environmental changes and disturbances;
2) Assess the hydrological-related impacts of land use/cover change on forested systems;
3) Present new methods (e.g. remote sensing techniques) or tools that unveil new perspectives or data sources in forest hydrology;
4) Include interdisciplinary research that holistically integrates data and models from soil–plant–atmosphere experimental or modelling schemes into hydrological studies.
Despite only representing about 25% of continental land, mountains are an essential part of the global ecosystem and are recognised to be the source of much of the world’s surfaces water supply apart from important sources of other commodities like energy, minerals, forest and agricultural products, and recreation areas. In addition, mountains represent a storehouse for biodiversity and ecosystem services. People residing within mountains or in their foothills represent approximately 26% of the world’s population, and this percentage increases to nearly 40% when considering those who live within watersheds of rivers originated in a mountain range. This makes mountains particularly sensitive to climate variability, but also unique areas for identifying and monitoring the effects of global change thanks to the rapid dynamics of their physical and biological systems.
This session aims to bring together the scientific community doing hydrology research on mountain ranges across the globe to share results and experiences. Therefore, this session invites contributions addressing past, present and future changes in mountain hydrology due to changes in either climate and/or land use, how these changes affect local and downstream territories, and adaptation strategies to ensure the long-term sustainability of mountain ecosystem services, with a special focus on water cycle regulation and water resources generation. Example topics of interest for this session are:
• Sources of information for evaluating past and present conditions (in either surface and/or ground water systems).
• Methods for differentiating climatic and anthropogenic drivers of hydrological change.
• Modelling approaches to assess hydrological change.
• Evolution, forecasting and impacts of extreme events.
• Case studies on adaptation to changing water resources availability.

Water stored in the snow pack and in glaciers represents an important component of the hydrological budget in many regions of the world, as well as a sustainment to life during dry seasons. Predicted impacts of climate change in catchments covered by snow or glaciers (including a shift from snow to rain, earlier snowmelt, and a decrease in peak snow accumulation) will reflect both on water resources availability and water uses at multiple scales, with potential implications for energy and food production.
The generation of runoff in catchments that are impacted by snow or ice, profoundly differs from rainfed catchments. And yet, our knowledge of snow/ice accumulation and melt patterns and their impact on runoff is highly uncertain, because of both limited availability and inherently large spatial variability of hydrological and weather data in such areas. This translates into limited process understanding, especially in a warming climate.
This session aims at bringing together those scientists that define themselves to some extent as cold region hydrologists, as large as this field can be. Contributions addressing the following topics are welcome:
- Experimental research on snow-melt & ice-melt runoff processes and potential implementation in hydrological models;
- Development of novel strategies for snowmelt runoff modelling in various (or changing) climatic and land-cover conditions;
- Evaluation of remote-sensing or in-situ snow products and application for snowmelt runoff calibration, data assimilation, streamflow forecasting or snow and ice physical properties quantification;
- Observational and modelling studies that shed new light on hydrological processes in glacier-covered catchments, e.g. impacts of glacier retreat on water resources and water storage dynamics or the application of techniques for tracing water flow paths;
- Studies on cryosphere-influenced mountain hydrology, such as landforms at high elevations and their relationship with streamflow, water balance of snow/ice-dominated mountain regions;
- Studies addressing the impact of climate change on the water cycle of snow and ice affected catchments.

Large data samples of diverse catchments can provide insights into relevant physiographic and hydroclimatic factors that shape hydrological processes. Further, large data sets increasingly cover a wide variety of hydrologic conditions, enabling the development of several research topics, such as extreme events, data and model uncertainty, hydrologic model evaluation and prediction in ungauged basins.
This session aims to showcase recent data and model-based efforts on large-sample hydrology, which advance the characterization, organization, understanding and modelling of hydrological diversity. We specifically welcome abstracts that seek to accelerate progress on the following topics:
1. Development and improvement of large-sample data sets:
How can we address current challenges on the unequal geographical representation of catchments, quantification of uncertainty, catchment heterogeneities and human interventions for fair comparisons among datasets?
2. Catchment similarity and regionalization:
Can currently available global datasets be used to define hydrologic similarity? How can information be transferred between catchments?
3. Modelling capabilities:
How can we improve hydrological modelling by using large samples of catchments?
4. Testing of hydrologic theories:
How can we use large samples of catchments to transfer hydrologic theories from well-monitored to data-scarce catchments?
5. Identification and characterization of dominant hydrological processes:
How can we use catchment descriptors available in large sample datasets to infer dominant controls for relevant hydrological processes?
6. Human impacts and non-stationarity
How can we use large samples of catchment data to infer hydrological response under changing environmental conditions?
A splinter meeting is planned to discuss and coordinate the production of large-sample data sets, entitled “Large sample hydrology: facilitating the production and exchange of data sets worldwide”. See the final programme for location and timing.
The session and the splinter meeting are organized as part of the Panta Rhei Working Group on large-sample hydrology.
Understanding and representing hydrological processes is the basis for developing and improving hydrological and Earth system models. Relevant hydrological data are becoming globally available at an unprecedented rate, opening new avenues for modelling (model parametrization, evaluation, and application) and process representation. As a result, a variety of models are developed and trained by new quantitative and qualitative data at various temporal and spatial scales.
In this session, we welcome contributions on novel frameworks for model development, evaluation and parametrization across spatio-temporal scales.
Potential contributions could (but are not limited to):
(1) introduce new global and regional data products into the modeling process;
(2) upscale experimental knowledge from smaller to larger scale for better usage in catchment models;
(3) advance seamless modeling of spatial patterns in hydrology and land models using distributed earth observations;
(4) improve model structure by representing often neglected processes in hydrological models such as human impacts, river regulations, irrigation, as well as vegetation dynamics;
(5) provide novel concepts for improving the characterization of internal and external model fluxes and their spatio-temporal dynamics;
(6) introduce new approaches for model calibration and evaluation, especially to improve process representation, and/or to improve model predictions under changing conditions;
(7) develop novel approaches and performance metrics for evaluating and constraining models in space and time

The application of multi-datasets and multi-objective functions has proven to improve the performance of hydrologic and water quality models by extracting complementary information from multiple data sources or multiple features of modelled variables. This is useful if more than one variable (runoff and snow cover, sediment, pollutant concentration, or stable isotope) or more than one characteristic of the same variable (e.g., flood peaks and recession curves) are of interest. Similarly, a multi-model approach can overcome shortcomings of individual models, while testing a model at multiple scales using a large sample of catchments helps to improve our understanding of the model functioning in relation to catchment processes. The use of multiple data sources in data-driven approaches can help engineering data-driven models with higher predictability skills. Finally, the quantification of multiple uncertainty sources enables the identification of their contributions and this is critical for uncertainty reduction and decision making under uncertainty.
This session welcomes contributions that apply one or more of the multi-aspects in hydrological, ecological and water quality studies. In particular, we seek studies covering the following issues:
• Frameworks using multi-objective or multi-variables to improve the identification (prediction) of hydrological, ecological or water quality models;
• Studies using multi-model or multiple-data-driven approaches;
• Use of multiple scales, sites or large-sample studies to improve understanding of catchment processes;
• Assimilation of remote sensed data or use of multi-datasets to improve model identification;
• Hypothesis testing with one of the multi-aspects
• Metaheuristics (e.g., Monte Carlo) or Bayesian approaches in combination with multi-aspects of model identification;
• Techniques to optimize model calibration or uncertainty quantification via multi-aspect analyses;
• Studies handling multiple uncertainty sources in a modelling framework.
• Application of machine learning and data mining approaches to learn from large, multiple or high-resolution data sets.

The importance of soil moisture for the hydrological systems dynamics is undebated. A great deal of observations and research have been invested in the last decades to improve the knowledge of soil water status as well its spatial and temporal variation within a given hydrological system. In that effort, several types of soil moisture data have become available, spanning from in-situ observations, radar data, cosmic ray studies to several satellite products.
Although spatial and temporal patterns of soil moisture are the result of processes that hydrological models typically capture, the application of the currently available soil moisture information for improving models is progressing only slowly. This is partly due to a gap between the information content provided by the available data and the information required to improve models. Furthermore, some essential parts of soil water storage at the larger scale, like that of the root zone, is typically assessed using combination of models and data, resulting in a lack of independent information for validation.
This session invites contributions dealing with closing these gaps. This could, for example, be achieved by progress in the descriptions of the processes causing the spatial and temporal variations in soil moisture or by more efficiently using information from available data to improve model predictions across scales. The session is explicitly open for research across all relevant hydrological scales: local, hillslope, catchment up to the continental scale, and deal with both the vertical and lateral flow processes.
Examples for suitable contributions are (but are not limited to):
- The role of soil moisture in the functioning of hydrological systems
- Methods and case studies on improving the predictive power of models using soil moisture data
- Deriving process knowledge from soil moisture data that can be used to improve hydrological models
- Evaluating the suitability of given soil moisture data types for representing hydrologic processes

Land use and climate change as well as legal requirements (e.g. the EU Water Framework Directive) pose challenges for the assessment and sustainable management of surface water quality at the catchment scale. Sources and pathways of nutrients and other pollutants as well as nutrient interactions have to be characterized to understand and manage the impacts in river systems. Additionally, water quality assessment needs to cover the chemical and ecological status to link the hydrological view to aquatic ecology.
Models can help to optimize monitoring schemes and provide assessments of future change and management options. However, insufficient temporal and/or spatial resolution, a short duration of observations and the widespread use of different analytical methods restrict the data base for model application. Moreover, model-based water quality calculations are affected by errors in input data, model errors, inappropriate model complexity and insufficient process knowledge or implementation. Additionally, models should be capable of representing changing land use and climate conditions, which is a prerequisite to meet the increasing needs for decision making. The strong need for advances in water quality models remains.
This session aims to bring scientist together who work on experimental as well as on modelling studies to improve the prediction and management of water quality constituents (nutrients, organic matter, algae, or sediment) at the catchment scale. Contributions are welcome that cover the following issues:
- Experimental and modelling studies on the identification of sources, hot spots, pathways and interactions of nutrients and other, related pollutants at the catchment scale
- New approaches to develop efficient water quality monitoring schemes
- Innovative monitoring strategies that support both process investigation and model performance
- Advanced modelling tools integrating catchment as well as in-stream processes
- Observational and modelling studies at catchment scale that relate and quantify water quality changes to changes in land use and climate
- Measurements and modelling of abiotic and biotic interaction and feedback involved in the transport and fate of nutrients and other pollutants at the catchment scale
- Catchment management: pollution reduction measures, stakeholder involvement, scenario analysis for catchment management

Water quantity and quality is typically assessed and managed at the scales of catchments and aquifers. However, flow and transport integrate a multitude of hydrological transport and biogeochemical reaction processes interacting at different temporal and spatial scales, and thus hampering the understanding of underlying cause-effect relationships.
Recent advances in high-frequency measurements, machine learning, and the use of age tracers and their modelling have enhanced process understanding of flow and transport in catchments and aquifers. Our session brings together studies approaching this challenge from different angles and with different tools:
- Data-driven interpretation of water quality time series observed at the catchment outlet
- Isotope- and model-driven evaluation of transit times and water ages in catchments including the groundwater compartment
- Linkages of water transit times, hydrochemical and ecohydrological response
Stable and radioactive isotopes as well as other natural and artificial tracers are useful tools to fingerprint the source of water and solutes in catchments, to trace their flow pathways or to quantify exchanges of water, solutes and particulates between hydrological compartments. Papers are invited that demonstrate the application and recent developments of isotope and other tracer techniques in field studies or modelling in the areas of surface / groundwater interactions, unsaturated and saturated zone, rainfall-runoff processes, nutrient or contaminant export, ecohydrology or other catchment processes.

The occurrence of pathogens and an exponentially increasing number of contaminants in freshwater and estuary environments pose a serious problem to public health. This problem is likely to increase in the future due to more frequent and intense storm events, the intensification of agriculture, population growth and urbanization. Pathogens (e.g., pathogenic bacteria and viruses) are introduced into surface water through the direct discharge of wastewater, or by the release from animal manure or animal waste via overland flow or groundwater, which subsequently presents potential risks of infection when used for drinking, recreation or irrigation. Contaminants of emerging concern are released as diffuse sources from anthropogenic activities or as discharges from wastewater treatment plants (e.g., trace organic contaminants). So far, the sources, pathways and transport mechanisms of fecal indicators, pathogens and emerging contaminants in water environments are poorly understood, and thus we lack a solid basis for quantitative risk assessment and selection of best mitigation measures. Innovative, interdisciplinary approaches are needed to advance this field of research. In particular, there is a need to better understand the dominant processes controlling fecal indicator, pathogen and contaminant fate and transport at larger scales. Consequently, we welcome contributions that aim to close these knowledge gaps and include both small and large-scale experimental and modelling studies with a focus on:
- The development and application of novel experimental and analytical methods to investigate fate and transport of fecal indicators, pathogens and emerging contaminants in rivers, groundwater and estuaries
- Hydrological, physically based modelling approaches
- Methods for identifying the dominant processes and for transferring fecal indicator, pathogen and contaminant transport parameters from the laboratory to the field or catchment scale
- Investigations of the implications of contamination of water resources for water safety management planning and risk assessment frameworks

A large number of pathogens, micropollutants and their transformation products (veterinary and human pharmaceuticals, personal care products, pesticides and biocides, chlorinated compounds, PFAS, heavy metals) pose a risk for soil, groundwater and surface water. The large diversity of compounds and of their sources makes the quantification of their occurrence in the terrestrial and aquatic environment across space and time a challenging task. Regulatory monitoring programmes cover a small selection out of the compound diversity and quantify these selected compounds only at coarse temporal and spatial resolution. Carefully designed monitoring however allows to detect and elucidate processes and to estimate parameters in the aquatic environment. Modelling is a complementary tool to generalize measured data and extrapolate in time and space, which is needed as a basis for scenario analysis and decision making. Mitigation measures can help reduce contamination of ground- and surface water and impacts on water quality and aquatic ecosystems.
This session invites contributions that improve our quantitative understanding of the sources and pathways, mass fluxes, the fate and transport and the mitigation of micropollutants and pathogens in the soil-groundwater-river continuum.
Topics cover:
- Novel sampling and monitoring concepts and devices
- New analytical methods, new detection methods for DNA, pathogens, micropollutants, non-target screening
- Experimental studies and modelling approaches to quantify diffuse and point source inputs
- Novel monitoring approaches such as non-target screening as tools for improving processes understanding and source identification such as industries
- Comparative fate studies on parent compounds and transformation products
- Diffuse sources and (re-)emerging chemicals
- Biogeochemical interactions and impact on micropollutant behaviour
- Setup of mitigation measures and evaluating their effectiveness.
Plastic pollution in freshwater systems is a widely recognized global problem with potential environmental risks to water and sediment quality. Furthermore, freshwater plastic pollution is also considered the dominant source of plastic input to the oceans. Despite this, research on plastic pollution has only recently expanded from the marine environment to freshwater systems. Therefore data and knowledge from field studies are still limited in regard to freshwater environments. Sources, quantities, distribution across environmental matrices and ecosystem compartments, and transport mechanisms remain mostly unknown at catchment scale. These knowledge gaps must be addressed to understand the dispersal and eventual fate of plastics in the environment, enabling a better assessment of potential risks as well as development of effective mitigation measures.
In this session, we explore the current state of knowledge and activities on macro-, micro- and nanoplastics in freshwater systems, including aspects such as:
• Plastics in rivers, lakes, urban water systems, floodplains, estuaries, freshwater biota;
• Monitoring and analysis techniques;
• Source to sink investigations, considering quantities and distribution across environmental matrices (water and sediment) and compartments (water surface layer, water column, ice, riverbed, and riverbanks);
• Transport processes of plastics at catchment and local scale;
• The role of river regulation structures, e.g. dams, navigation, flood control, etc., in plastic retention and transport
• Effects of hydrological extremes, e.g. accumulation of plastics during droughts, and short-term export during floods in the catchment;
• Degradation and fragmentation processes, e.g. from macro- to micro- and nanoplastics;
• Modelling approaches for local and/or global river output estimations;
• Legislative/regulatory efforts, such as monitoring programs and measures against plastic pollution in freshwater systems.
Bayesian approaches have become increasingly popular in water quality modelling, thanks to their ability to handle uncertainty comprehensively. This is particularly relevant in environmental decision making where Bayesian inference enables to consider the reliability of predictions of the consequences of decision alternatives, alongside uncertainties related to decision makers’ risk attitudes and preferences, uncertainty related to system understanding and random processes. Graphical Bayesian Belief Networks and related approaches (hierarchical models, ‘hybrid’ mechanistic/data-driven models) can be particularly powerful decision support tools that make it relatively easy for stakeholders to engage in the model building process and inform adaptive water quality management within an uncertainty framework. The aim of this session is to review the state-of-the-art in this field and compare software and procedural choices to consolidate and set new directions for the emerging community of Bayesian water quality modellers. Building on past three years’ success of this session, a specific new emphasize for this year’s session is to explore the utility of Bayesian water quality models in supporting decision making.
We seek contributions from water quality research that use Bayesian approaches to, for example but not exclusively:
• involve stakeholders in model development and maximise the use of expert knowledge
• integrate prior knowledge, especially problematizing the choice of Bayesian priors
• inform risk analysis and decision support using diverse data and evidence
• represent the preferences of the stakeholders in the form of value functions through elicitation, and account for the uncertainty in preferences
• produce accessible decision support tools
• model water quality in data sparse environments
• compare models with different levels of complexity and process representation
• quantify the uncertainty of model predictions (due to data, model structure and parameter uncertainty)
• address the problem of scaling (e.g. disparity of scales between processes, observations, model resolution and predictions) through hierarchical models
• quantify especially model structural error through, for example, Bayesian Model Averaging or structural error terms
• use statistical emulators to allow probabilistic predictions of complex modelled systems
• use machine-learning and data mining approaches to learn from large, possibly high-resolution data sets.

In the current context of global change, assessing the impact of climate variability and changes on hydrological systems and water resources is increasingly crucial for society to better-adapt to future shifts in water resources, as well as extreme conditions (floods and droughts). However, important sources of uncertainty have often been neglected in projecting climate impacts on hydrological systems, especially uncertainties associated with internal/natural climate variability, whose contribution to near-future changes could be as important as forced anthropogenic climate changes at the regional scales. Internal climate modes of variability (e.g. ENSO, NAO, AMO) and their impact on the continent are not always properly reproduced in the current global climate models, leading to large underestimations of decadal climate and hydro-climatic variability at the global scale. At the same time, hydrological response strongly depends on catchment properties, whose interactions with climate variability are little understood at the decadal timescales. These factors altogether significantly reduce our ability to understand long-term hydrological variability and to improve projections and reconstructions of future and past hydrological changes upon which improvement of adaption scenarios depends.
We welcome abstracts capturing recent insights for understanding past or future impacts of large-scale climate variability on hydrological systems and water resources as well as newly developed projection and reconstruction scenarios. Results from model intercomparison studies are encouraged.
This session focusses on hydrological response to changes in climatic forcing at multi-annual to multi-decadal timescales. Catchments are immensely complex and unique systems responding to external factors (e.g. changes in climate) on a variety of timescales due to complex interactions and feedbacks between their components. Recent evidence suggests a tendency for existing models and methods to downplay the impact of a given climatic change on streamflow with major implications for the reliability of such methods for future planning. The poor performance of models suggests they potentially misrepresent (or omit) important catchment processes, process timescales, or interactions between processes. The multitude of responses and feedbacks developing in the critical zone need to be disentangled and understood to improve our ability to make hydrological predictions under different and continuously changing climatic conditions.
We invite submissions on themes such as (but not limited to):
1. Better understanding of hydrological and/or biophysical processes related to long-timescale climate shifts potentially contributing to apparent shifts in hydrologic response;
2. Understanding and quantifying catchment multi-annual “memory”
3. Modelling studies aiming to evaluate and/or improve hydrologic simulations under historic climatic variability and change;
4. Efforts to improve the realism of runoff projections under future climate scenarios;
5. Studies that explore implications of long term-hydrologic change for water availability, risk, or environmental outcomes including interactions with human factors such as landuse changes, evolving water policy, and management intervention.
The space-time dynamics of floods are controlled by atmospheric, catchment, river system and anthropogenic processes and their interactions. The natural oscillatory behaviour of floods (between flood-rich and flood-poor periods) superimpose with anthropogenic climate change and human interventions in river morphology and land uses. In addition, flood risk is further shaped by continuous changes in exposure and vulnerability. Despite more frequent exploratory analyses of the changes in spatio-temporal dynamics of flood hazard and risk, it remains unclear how and why these changes are occurring. The scope of this session is to report when, where, how (detection) and why (attribution) changes in the space-time dynamics of floods occur. Of particular interest is what drivers are responsible for observed changes. Presentations on the impact of climate variability and change, land use changes and morphologic changes in streams, as well as on the role of pre-flood catchment conditions in shaping flood hazard and risk are welcome. Furthermore, contributions on the impact of structural measures and demographic and socio-economic factors on past and future risk changes are invited. This session is jointly organised by the Panta Rhei Working Groups “Understanding Flood Changes” and “Changes in Flood Risk”. The session will further stimulate scientific discussion on flood change detection and attribution. Specifically, the following topics are of interest for this session:
- Decadal oscillations in rainfall and floods
- Process-informed extreme value statistics
- Interactions between spatial rainfall and catchment conditions shaping flood patterns
- Detection and attribution of flood hazard changes: atmospheric drivers, land use controls and river training, among others
- Changes in flood risk: urbanisation of flood prone areas; implementation of multi-scale risk mitigation measures, such as natural water retention measures and private precautionary measures; changes of economic, societal and technological aspects driving flood vulnerability and damages, among others.
- Future flood risk scenarios and the role of adaptation and mitigation strategies

Hydrological extremes (floods and droughts) have major impacts on society and ecosystems and are posited to increase in frequency and severity with climate change. These events at the two ends of the hydrological spectrum are governed by different processes, which means that they operate on different spatial and temporal scales and that different approaches and indices are needed to characterise them. However, there are also many similarities and links between the two types of extremes that are increasingly being studied.
This session on hydrological extremes aims to bring together the flood and drought communities to learn from the similarities and differences between flood and drought research. We aim to increase the understanding of the governing processes of both types of hydrological extremes, find robust ways of modelling and analysing floods and droughts, assess the influence of global change on hydro-climatic extremes, and study the socio-economic and environmental impacts of both types of extremes.
We welcome submissions that present insightful flood and/or drought research, including case studies, large-sample studies, statistical hydrology, and analysis of flood or drought non-stationarity under the effects of climate-, land cover-, and other anthropogenic changes. These might include storyline and stress testing approaches to better understand hydrological responses under changed (extreme) conditions. Studies that investigate both types of extremes are of particular interest. Submissions from early-career researchers are especially encouraged.
Large-scale hydrological research is very important in many different contexts - examples include: increase understanding of the climate system and water cycle, assessment of water resources in a changing environment, hydrological forecasting, and transboundary water resource management.
We invite contributions from across hydrological, atmospheric, and earth surface processes communities. In particular, we welcome abstracts that address advances in:
(i) understanding and predicting the current and future state of our global and large scale water resources;
(ii) use of global earth observations and in-situ datasets for large scale hydrology and data assimilation techniques for large scale hydrological models;
(iii) understanding and modelling of extremes: like droughts and floods;
(iv) representing and evaluating different components of the terrestrial water cycle fluxes and storages (e.g. soil moisture, snow, groundwater, lakes, floodplains, evaporation, river discharge) and their impact on current and future water resources and atmospheric modelling;
(v) synthesis studies assembling knowledge gained from smaller scales (e.g. catchments or hillslope) to advance our knowledge on process understanding needed for the further development of large-scale models and to identify large-scale patterns and trends.

Since early work on the assessment of global, continental and regional-scale water balance components, many studies use different approaches including global models, as well as data-driven approaches that ingest in-situ or remotely sensed observations or combinations of these. They attempted to quantify water fluxes (e.g. evapotranspiration, streamflow, groundwater recharge) and water storage on the terrestrial part of the Earth, either as total estimates (e.g. from GRACE satellites) or in separate compartments (e.g. water bodies, snow, soil, groundwater). In addition, increasing attention is given to uncertainties that stem from forcing datasets, model structure, parameters and combinations of these. Current estimates in literature show that flux and storage estimates differ considerably due to the methodology and datasets used such that a robust assessment of global, continental and regional water balance components remains challenging.
This session is seeking for contributions focusing on:
i. past/future assessment of water balance components (fluxes and storages) such as precipitation, freshwater fluxes to the oceans (and/or inland sinks), evapotranspiration, groundwater recharge, water use, changes in terrestrial water storage or individual components at global, continental and regional scales,
ii. application of innovative explorative approaches undertaking such assessments – through better use of advanced data driven, statistical approaches and approaches to assimilate (or accommodate) remote sensing datasets for improved estimation of terrestrial water storages/fluxes,
iii. analysis of different sources of uncertainties in estimated water balance components,
iv. examination and attribution of systematic differences in storages/flux estimates between different methodologies, and/or
v. applications/consequences of those findings such as sea level rise and water scarcity.
We encourage submissions using different methodological approaches. Contributions could focus on any of the water balance components or in an integrative manner with focus on global, continental or regional scale applications. Assessments of uncertainty in past/future estimates of water balance components and their implications are highly welcome.
Groundwater provides about 40% of all human water abstractions and is an essential water source for freshwater biota in rivers, lakes, and wetlands. Aquifers may span political and natural boundaries, but our large-scale understanding of groundwater processes and their interconnection to surface water is still limited.
Increasingly global-scale groundwater models are being developed, and big-data assessments of groundwater wells have been conducted to push the boundaries of our large-scale understanding of groundwater processes. Similar to the catchment scale, knowledge of the exchange between surface and subsurface waters is essential for determining the hydrological water balance at larger scales. Furthermore, surface and subsurface waters exchanges, as well as inter-catchment groundwater flow, affect water, pollutant and nutrient fluxes, bio-organisms in streams, and the groundwater itself. Additionally, human activities (e.g., pumping/irrigation) could alter the natural conditions for the groundwater flow processes and exchange between surface and subsurface.
In this session, we want to highlight the increasing interest in the large-scale study of groundwater availability and processes while discussing current obstacles related to data availability and model design. Therefore, we seek contributions addressing issues including:
• Regional to global groundwater-related datasets and big-data assessments
• Transboundary and inter-catchment assessments of groundwater processes
• Surface-subsurface water exchange at the catchment to global scales from both observational and modeling aspects
• Effects of surface-subsurface water exchange on hydrological extremes (drought/flood), water availability, and solute and pollutant transport under climate change
• Implications of large-scale groundwater understanding on monitoring design and integrated water management beyond the catchment scale
• Variation of controls on groundwater processes across large domains

Hydroinformatics has emerged over the last decades to become a recognised and established field. It is concerned with the development and hydrological application of mathematical modelling, ICT, systems science and computational intelligence tools. We also have to face the challenges of Big Data: large data sets, both in size and complexity.
The aim of this session is to provide an active forum in which to demonstrate and discuss the integration and appropriate application of emergent computational technologies in a hydrological modelling context. Topics of interest are expected to cover a broad spectrum of theoretical and practical activities that would be of interest to hydro-scientists and water-engineers. The main topics will address the following classes of methods and technologies:
* Methods for the analysis of complex data sets, including remote sensing and crowdsourced data
* Clustering algorithms: hard vs fuzzy clustering, comparison of methods, alternative clustering methods (sequential, evolutionary, deep, ensemble, etc.)
* Predictive and analytical models based on the methods of statistics, computational intelligence, machine learning and data science: neural networks, deep learning techniques, fuzzy systems, genetic programming, chaos theory, etc.
* Specific concepts and methods of Big Data and Data Science
* Optimisation methods associated with heuristic search procedures: various types of genetic and evolutionary algorithms, randomised and adaptive search, etc.
* Applications of systems analysis and optimisation in water resources
* Hybrid modelling involving different types of models both process-based and data-driven, combination of models (multi-models), etc.
* Data assimilation and model reduction in integrated modelling
* Novel methods of analysing model uncertainty and sensitivity
* Demonstrating the benefit of the use of Citizen Observatories, crowdsourcing, and innovative sensing techniques for monitoring, modelling, and management of water resources
* Software architectures for integrating different types of models and data sources
Applications could belong to any area of hydrology or water resources: rainfall-runoff modelling, flow forecasting, sedimentation modelling, analysis of meteorological and hydrologic data sets, linkages between numerical weather prediction and hydrologic models, model calibration, model uncertainty, optimisation of water resources, etc.
Many environmental and hydrological problems are spatial or temporal, or both in nature. Spatio-temporal analysis allows identifying and explaining large-scale anomalies which are useful for understanding hydrological characteristics and subsequently predicting hydrological events. Temporal information is sometimes limited; spatial information, on the other hand has increased in recent years due technological advances including the availability of remote sensing data. This development has motivated new research efforts to include data in model representation and analysis.
Statistics are in wide use in hydrology for example to estimate design events, forecast the risk and hazard of flood events, detect spatial or temporal clusters, model non-stationarity and changes and many more. Statistics are useful in the case when only few data are available but information for very rare events (extremes) or long time periods are needed. They are also helpful to detect changes and inconsistencies in the data and give a reliable statement on the significance. Moreover, temporal and spatial changes often lead to the violation of stationarity, a key assumption of many standard statistical approaches. This makes hydrological statistics interesting and challenging for so many researchers.
Geostatistics is the discipline that investigates the statistics of spatially extended variables. Spatio-temporal analysis is at the forefront of geostatistical research these days, and its impact is expected to increase in the future. This trend will be driven by increasing needs to advance risk assessment and management strategies for extreme events such as floods and droughts, and to support both short and long-term water management planning. Current trends and variability of hydrological extremes call for spatio-temporal and/or geostatistical analysis to assess, predict, and manage water related and/or interlinked hazards.
The aim of this session is to provide a platform and an opportunity to demonstrate and discuss innovative applications and methodologies of spatio-temporal analysis in a hydrological (hydrometeorological) context. The session is targeted at both hydrologists and statisticians interested in the spatial and temporal analysis of hydrological events, extremes, and related hazards, and it aims to provide a forum for researchers from a variety of fields to effectively communicate their research.

Proper characterization of uncertainty remains a major research and operational challenge in Environmental Sciences, and is inherent to many aspects of modelling impacting model structure development; parameter estimation; an adequate representation of the data (inputs data and data used to evaluate the models); initial and boundary conditions; and hypothesis testing. To address this challenge, methods for a) uncertainty analysis (UA) that seek to identify, quantify and reduce the different sources of uncertainty, as well as propagating them through a system/model, and b) the closely-related methods for sensitivity analysis (SA) that evaluate the role and significance of uncertain factors (in the functioning of systems/models), have proved to be very helpful.
This session invites contributions that discuss advances, both in theory and/or application, in methods for SA/UA applicable to all Earth and Environmental Systems Models (EESMs), which embraces all areas of hydrology, such as classical hydrology, subsurface hydrology and soil science.
Topics of interest include (but are not limited to):
1) Novel methods for effective characterization of sensitivity and uncertainty
2) Analyses of over-parameterised models enabled by AI/ML techniques
3) Single- versus multi-criteria SA/UA
4) Novel approaches for parameter estimation, data inversion and data assimilation
5) Novel methods for spatial and temporal evaluation/analysis of models
6) The role of information and error on SA/UA (e.g., input/output data error, model structure error, parametric error, regionalization error in environments with no data etc.)
7) The role of SA in evaluating model consistency and reliability
8) Novel approaches and benchmarking efforts for parameter estimation
9) Improving the computational efficiency of SA/UA (efficient sampling, surrogate modelling, parallel computing, model pre-emption, model ensembles, etc.)
To provide support for resource management decision making, computational modeling workflows in hydrosystem simulation need to be efficient, reproducible, and robust with regard to the risk of unwanted outcomes. Unfortunately, each of these three attributes is difficult to achieve in practice; aspirations to simultaneously achieve all of them are truly lofty. Too often, modeling analyses are inefficient, the workflow is largely opaque and unknown, and the important simulated outcomes lack the context of uncertainty and/or risk.
This session calls for submissions that demonstrate rapid, reproducible and/or robust modeling through worked examples and software tools (a preference for open source). The worked examples should demonstrate how the researcher aspired to be rapid, reproducible, and robust; we are interested in the process and approach as much as the results. We aim to stimulate discussion based on lessons learned and results presented, for other researchers and practitioners to build on. We particularly welcome descriptions of trials and tribulations: What was difficult? What didn’t work? How were these issues overcome?
Software tools may include:
• techniques to automate modeling workflow elements or increase efficiency, reproducibility, robustness of decision-support modeling elements.
• frameworks to build models from original data in flexible ways that may enable hypothesis testing in the form of changing discretization, process representation, and other modeling decisions.
• multi-model frameworks such as Bayesian-model selection/combination, as well as frameworks to accommodate model structural error.
• Methods for uncertainty analysis, data assimilation, and management optimization under uncertainty in the decision-support context.
• machine-learning approaches for decision support analyses.

Flash floods triggered by heavy precipitation in small- to medium-sized catchments often cause catastrophic damages, which are largely explained by the very short response times and high specific peak discharge. Often, they are also associated with geomorphic processes such as erosion, sediment transport, debris flows and shallow landslides. The anticipation of such events is crucial for efficient crisis management. However, their predictability is still affected by large uncertainties, due to the fast evolution of triggering rainfall events, the lack of appropriate observations, the high variability and non-linearity in the physical processes, the high variability of societal exposure, and the complexity of societal vulnerability.
This session aims to illustrate current advances in monitoring, modeling, and short-range forecasting of flash floods and associated geomorphic processes, including their societal impacts.
Contributions related to the floods that occured in July 2021 in Germany and Western Europe, and in October 2020 in France and Italy (Alex storm) are particularly encouraged this year.
Contributions on the following scientific themes are specifically expected:
- Monitoring and nowcasting of heavy precipitation events based on radar and remote sensing (satellite, lightning, etc.) to complement rain gauge networks;
- Short-range (0-6h) heavy precipitation forecasting based on NWP models, with a focus on seamless forecasting strategies and ensemble strategies for the representation of uncertainties;
- Understanding and modeling of flash floods and associated geomorphic processes at appropriate space-time scales;
- Development of integrated hydro-meteorological forecasting chains and new modeling approaches for predicting flash floods and/or rainfall-induced geomorphic hazards in gauged and ungauged basins;
- New direct and indirect (proxy data) observation techniques and strategies for the observation or monitoring of hydrological reactions and geomorphic processes, and the validation of forecasting approaches;
- Development of impact-based modeling and forecasting approaches, including inundation mapping and/or specific impacts modeling approaches for the representation of societal vulnerability.
Drought and water scarcity are important issues in many regions of the Earth. While the projected increase in the severity and frequency of droughts can lead to water scarcity situations, particularly in regions that are already water-stressed, overexploitation of available water resources can exacerbate the consequences of droughts. In the worst case, this can lead to long-term environmental and socio-economic impacts. Drought Monitoring and Forecasting are recognized as one of three pillars of effective drought management, and it is, therefore, necessary to improve both monitoring and sub-seasonal to seasonal forecasting for droughts and water availability and to develop innovative indicators and methodologies that translate the information provided into effective drought early warning and risk management. This session addresses statistical, remote sensing and physically-based techniques, aimed at monitoring, modelling and forecasting hydro-meteorological variables relevant to drought and/or water scarcity. These include, but are not limited to, precipitation, snow cover, soil moisture, streamflow, groundwater levels, and extreme temperatures. The development and implementation of drought indicators meaningful to decision-making processes, and ways of presenting and integrating these with the needs and knowledge of water managers, policymakers and other stakeholders, are further issues that are addressed. The session aims to bring together scientists, practitioners and stakeholders in the fields of hydrology and meteorology, as well as in the field of water resources and/or drought risk management, also including drought and water scarcity interrelationship, hydrological impacts, and feedbacks with society. Particularly welcome are applications and real-world case studies in regions subject to significant water stress, where the importance of drought warning, supported through state-of-the-art monitoring and forecasting of water resources availability, is likely to become more important in the future.
This session brings together scientists, forecasters, practitioners and stakeholders interested in exploring the use of ensemble hydro-meteorological forecast techniques in hydrological applications: e.g., flood control and warning, reservoir operation for hydropower and water supply, transportation, and agricultural management. It will address the understanding of sources of predictability and quantification and reduction of predictive uncertainty of hydrological extremes in deterministic and ensemble hydrological forecasting. Uncertainty estimation in operational forecasting systems is becoming a more common practice. However, a significant research challenge and central interest of this session is to understand the sources of predictability and development of approaches, methods and techniques to enhance predictability (e.g. accuracy, reliability etc.) and quantify and reduce predictive uncertainty in general. Ensemble data assimilation, NWP preprocessing, multi-model approaches or hydrological postprocessing can provide important ways of improving the quality (e.g. accuracy, reliability) and increasing the value (e.g. impact, usability) of deterministic and ensemble hydrological forecasts. The models involved with the methods for predictive uncertainty, data assimilation, post-processing and decision-making may include machine learning models, ANNs, catchment models, runoff routing models, groundwater models, coupled meteorological-hydrological models as well as combinations (multimodel) of these. Demonstrations of the sources of predictability and subsequent quantification and reduction in predictive uncertainty at different scales through improved representation of model process (physics, parameterization, numerical solution, data support and calibration) and error, forcing and initial state are of special interest to the session.

This interactive session aims to bridge the gap between science and practice in operational forecasting for different climate and water-related natural hazards including their dynamics and interdependencies. Operational (early) warning systems are the result of progress and innovations in the science of forecasting. New opportunities have risen in physically based modelling, coupling meteorological and hydrological forecasts, ensemble forecasting, impact-based forecasting and real time control. Often, the sharing of knowledge and experience about developments are limited to the particular field (e.g. flood forecasting or landslide warnings) for which the operational system is used. Increasingly, humanitarian, disaster risk management and climate adaptation practitioners are using forecasts and warning information to enable anticipatory/ early action that saves lives and livelihoods. It is important to understand their needs, their decision-making process and facilitate their involvement in forecasting and warning design and implementation (co-development).
The focus of this session will be on bringing the expertise from different fields together as well as exploring differences, similarities, problems and solutions between forecasting systems for varying hazards including climate emergency. Real-world case studies of system implementations - configured at local, regional, national, continental and global scales - will be presented, including trans-boundary issues. An operational warning system can include, for example, monitoring of data, analysing data, making and visualizing forecasts, giving warning signals and suggesting early action and response measures.
Contributions are welcome from both scientists and practitioners who are involved in developing and using operational forecasting and/or management systems for climate and water-related hazards, such as flood, drought, tsunami, landslide, hurricane, hydropower, pollution etc. We also welcome contributions from early career practitioners and scientists.

The Sendai Framework for Disaster Risk Reduction (SFDRR) and its seventh global target recognizes that increased efforts are required to develop risk-informed and impact-based multi-hazard early warning systems. Despite significant advances in disaster forecasting and warning technology, it remains challenging to produce useful forecasts and warnings that are understood and used to trigger early actions. Overcoming these challenges requires understanding of the reliability of forecast tools and implementation barriers in combination with the development of new risk-informed processes. It also requires a commitment to create and share risk and impact data and to co-produce impact-based forecasting models and services. To deal with the problem of coming into action in response to imperfect forecasts, novel science-based concepts have recently emerged. As an example, Forecast-based Financing and Impact-based Multi-Hazard Early Warning Systems are currently being implemented operationally by both governmental and non-governmental organisations in several countries as a result of increasing international effort by several organizations such as the WMO, World Bank, IFRC and UNDRR to reduce disaster losses and ensuring reaching the objectives of SFDRR. This session aims to showcase lessons learnt and best practices on impact-based multi-hazards early warning system from the perspective of both the knowledge producers and users. It presents novel methods to translate forecast of various climate-related and geohazards into an impact-based forecast. The session addresses the role of humanitarian agencies, scientists and communities at risk in creating standard operating procedures for economically feasible actions and reflects on the influence of forecast uncertainty across different time scales in decision-making. Moreover, it provides an overview of state-of-the-art methods, such as using Artificial Intelligence, big data and space applications, and presents innovative ways of addressing the difficulties in implementing forecast-based actions. We invite submissions on the development and use of operational impact-based forecast systems for early action; developing cost-efficient portfolios of early actions for climate/geo-related impact preparedness such as cash-transfer for droughts, weather-based insurance for floods; assessments on the types and costs of possible forecast-based disaster risk management actions; practical applications of impact forecasts.

Many water sectors are already having to cope with extreme weather events, climate variability and change. In this context, predictions on sub-seasonal and seasonal to decadal timescales (i.e. horizons ranging from months to a decade) are an essential part of hydrological forecasting. By providing science-based and user-specific information on potential impacts of variations in water availability, operational hydro-meteorological and climate services are invaluable to a range of water sectors such as water resources management, drinking water supply, transport, energy production, agriculture, disaster risk reduction, forestry, health, insurance, tourism and infrastructure.
This session aims to cover the research and operational advances in climate and hydro-meteorological forecasting, and their implications on predicting water availability for servicing water sectors. It welcomes, without being restricted to, presentations on:
- Technical challenges in making use of climate data for hydrological modelling (e.g. downscaling, bias correction, temporal disaggregation, spatial interpolation),
- Lessons learnt from forecasting and managing present day extreme conditions,
- Improved representations of hydrological extremes in a future climate,
- Seamless forecasting, including downscaling and statistical post- and pre-processing,
- Propagation of uncertainty through the forecasting chain for impact assessment and decision-making,
- Operational hydro-meteorological forecasting systems, hydro-climate services, and tools,
- Effective methods to link stakeholder interests and scientific expertise (e.g. service co-generation).
The session will bring together research scientists and operational managers in the fields of hydrology, meteorology and climate, with the aim of sharing experiences and initiating discussions on this momentous topic. We encourage presentations that utilise the WWRP/WCRP subseasonal-to-seasonal (S2S) prediction project database, and all hydrological relevant applications.

The occurrences of extreme flood events have increased globally in the last two decades as noted by recent rare and catastrophic flooding events in Germany, Belgium, China, the USA and in the monsoon season of India. Advanced innovative methods and conceptual improvements in existing approaches are required to address the modelling and management of the spatial and temporal complexity of extreme floods. The observed increase in frequency and severity of events can be predicted by joint probabilistic analyses of precipitation and river flow extremes. Evidence from the rare extreme events indicates that assumptions of Holocene climate stationarity is not applicable anymore for hydrologic analysis and design. The observed significant changes in weather patterns and characteristics that lead to extreme precipitation in different parts of the world far exceeded the design capacities of local protection infrastructures and systems – resulting in massive flooding, casualties, and economic losses. The watershed response to the extreme precipitation is the worst when combined with saturated steep catchments combined with antecedent moisture conditions. Prediction of region-scale and localized extreme events well ahead of time is a real challenge. New design protocols have required that account for uncertainties in future meteorological events and provide flexibility in the design and operation of infrastructure to minimize the consequences of extreme events. Understanding the mechanisms of extreme precipitation and its hydro meteorological connection with flooding, especially under the circumstances of global climate change, is critical for flood prevention and mitigation. This session invites research papers that focus on scientific and technological developments in extreme precipitation estimation, flood monitoring, and flood modelling, with the end goal of improving flood prevention and mitigation. The research studies discussing advancements in situ measurement and remote sensing of extreme precipitation, rainfall-runoff modelling, statistical and hydrological analysis of extreme precipitation and flood, flood forecasting and warning, and impact assessment of climate change and land use/cover change on flood are also invited. Research works that emphasize and discuss case studies on modelling extreme events are also expected to gain and learn from insights gained from flood disaster modelling and management.
Water sustains societies, economies and ecosystem services globally. Increasing water demands from population growth, coupled with shifts in water availability due to climate and land use change, are increasing competition and conflict over access to and use of freshwater resources in many regions. To address these challenges, integrative approaches to water management and policy are required to balance and manage trade-offs between social, economic and environmental uses of water. This session will provide a forum for showcasing novel and emerging research at the intersection of agricultural production, energy security, economic development, and environmental conservation. In particular, we encourage contributions to the session that: (i) identify knowledge gaps and improvements to understanding about the critical interconnections, feedbacks, and risks between system components, (ii) highlight development of new methods or tools for evaluating and monitoring trade-offs and performance in water allocation and management between different users and sectors, (iii) evaluate alternative technical, policy, and/or governance solutions to address water-food-energy-environment system challenges in different locations and at various scales (local, regional, and/or global), and (iv) discuss examples of more and less successful initiatives within research and policy designed to facilitate integrative planning of water-food-energy-environment systems.
Hydropower is a mature and cost-competitive renewable energy source, which helps stabilize fluctuations between energy demand and supply. The structural and operational differences between hydropower systems and renewable energy farms may require changes in the way hydropower facilities operate to provide balancing, reserves or energy storage. Yet, non-power constraints on hydropower systems, such as water supply, flood control, conservation, recreation, navigation may affect the ability of hydropower to adjust and support the integration of renewables. Holistic approaches that may span a range of spatial and temporal scales are needed to evaluate hydropower opportunities and support a successful integration maintaining a resilient and reliable power grid. In particular, there is a need to better understand and predict spatio-temporal dynamics between climate, hydrology, and power systems.
This session solicits academics and practitioners contributions that explore the use of hydropower and storage technologies to support the transition to low-carbon electricity systems. We specifically encourage interdisciplinary teams of hydrologists, meteorologists, power system engineers, and economists to present on case studies and discuss collaboration with environmental and energy policymakers.
Questions of interest include:
- Prediction of water availability and storage capabilities for hydropower production
- Prediction and quantification of the space-time dependences and the positive/negative feedbacks between wind/solar energies, water cycle and hydropower
- Energy, land use and water supply interactions during transitions
- Policy requirements or climate strategies needed to manage and mitigate risks in the transition
- Energy production impacts on ecosystems such as hydropeaking effects on natural flow regimes.

While water plays a critical role in sustaining human health, food security, energy production and ecosystem services, factors such as population growth, climate and land use change increasingly threaten water quality and quantity. The complexity of water resources systems requires methods integrating technical, economic, environmental, legal, and social issues within frameworks that help design and test efficient and sustainable water management strategies to meet the water challenges of the 21st century. System-scale analyses adopt practical, problem-oriented approaches for addressing the most challenging water issues of our times. These include competing objectives for water, multi-stakeholder planning and negotiation processes, multi-sector linkages, and dynamic adaptation under uncertainty. The session will feature state-of-the-art contributions to system-scale water management solutions for an uncertain environment.
Highly varying hydro-climatological conditions, multi-party decision-making contexts, and the dynamic interconnection between water and other critical infrastructures create a wealth of challenges and opportunities for water resources planning and management. For example, reservoir operators must account for a number of time-varying drivers, such as the downstream users’ demands, short- and long-term water availability, electricity prices, and the share of power supplied by wind and solar technologies. In this context, adaptive and robust management solutions are paramount to the reliability and resilience of water resources systems. To this purpose, emerging work is focusing on the development of models and algorithms that adapt short-term decisions to newly available information, often issued in the form of weather or streamflow forecasts, or extracted from observational data collected via pervasive sensor networks, remote sensing, cyberinfrastructure, or crowdsourcing.
In this session, we solicit novel contributions related to improved multi-sectoral forecasts (e.g., water availability and demand, energy and crop prices), novel data analytics and machine learning tools for processing observational data, and real-time control solutions taking advantage of this new information. Examples include: 1) approaches for incorporating additional information within control problems; 2) methods for characterizing the effect of forecast uncertainty on the decision-making process; 3) integration of information with users’ preferences, behavioral uncertainty, and institutional setting; 4) studies on the scalability and robustness of optimal control algorithms. We welcome real-world examples on the successful application of these methods into decision-making practice.

The world's energy, water, and land systems are in transition and rapidly integrating, driven by forces such as socioeconomic, demographic, climatic, and technological changes as well as policies intended to meet Sustainable Development Goals (SDGs) and other societal priorities. These dynamics weave across spatial scales, connecting global markets and trends to regional and sub-regional economies. At the same time, resources are often locally managed under varying administrative jurisdictions closely tied to inherent characteristics of each commodity such as river basins for water, grid regions for electricity and land-use boundaries for agriculture. Local decisions, in turn, are critical in deciding the aggregate success and consequences of national and global policies. Thus, there is a growing need to better characterise the energy-water-land nexus to guide robust and consistent decision making across these scales under changing climate.
This session aims to address this challenge for the energy-water-land nexus in nascent infrastructure planning and sectoral transitions. Contributions can include work dealing with applications of existing nexus approaches in sustainability assessment and design of future developments at different scales (i.e. urban to regional planning), as well as new methods that address existing gaps related to incorporating processes at different scales, bridging data gaps, improving optimisation approaches, or dealing with transboundary issues.

Land use and land cover (LULC) changes are one of the main drivers of changes to hydrological processes, altering the ecosystem dynamics and impacting the production of water-related ecosystem services (e.g. water provision, flood regulation, …) with different levels of societal impact.
LULC changes can be determined by anthropic and/or natural drivers and can affect many hydrological processes, including rainfall interception, evapotranspiration, moisture recycling, runoff generation, erosion, groundwater recharge, pollution and alteration of surface and groundwater quality. Such effects may in turn affect water-related ecosystem services and have an impact on the possible water-land nexus scenarios which should be understood, to inform effective and equitable water resources management.
This session therefore welcomes studies exploring different aspects of the water-land nexus, including, but not limited to:
• Advances in the quantification of hydrological impacts of LULC changes through modelling and experimental data, including water quantity and quality
• Disentanglement of LULC change impacts on all water resources management (blue, green, atmospheric) and water-related ecosystem services
• Assessments on the impact and extent of multi-level policies that drive LULC changes, as well as studies at the science-policy interface on the water-land nexus
• Advances in (interdisciplinary) methodologies for identifying water-related ecosystem services (WES), as well as studies highlighting spatial assessments of WES

For the improvement of water quality both the restoration of wetlands but also the establishment of different filter solutions such as constructed wetlands, bioreactors, integrated bufferzones and saturated bufferzones as drainage mitigation measures are important strategies applied for combating sediment and nutrient losses to surface waters as part of Water Framework Directive, River Basin Management Plans. It is essential to know the processes and driving factors behind that control sediment and nutrient retention and their relative importance over time to ensure the best management. Moreover, there is also a great need to learn about possible side-effects to avoid inter alia nutrient swapping. Perfect knowledge of the processes, namely their large spatial and temporal variability may never be achieved. Still, it is essential that we communicate what is known to water authorities and landscape managers to foster environmentally sound decision making. Additionally, other aspects, such as economic and social issues may vary greatly, even on a local scale, consequently such measures must be implemented as one element within a holistic and systemic management plan.
This session deals with various nature based and filter-based solutions to reduce the losses of sediment and nutrients from agriculture. The session looks for new advancements in already established measures, such as restoration of riparian wetlands, larger lowlands areas including fens and swamps, re-establishment of shallow lakes, constructed wetlands (surface flow and subsurface flow), as well as drainage mitigation measures recently introduced in Europe and still under development such as integrated buffer zones, saturated buffer zones and controlled drainage.

Urban areas are at risk from multiple hazards, including urban flooding, droughts and water shortages, sea level rise, disease spread and issues with food security. Consequently, many urban areas are adapting their approach to hazard management and are applying Green Infrastructure (GI) solutions as part of wider integrated schemes.
This session aims to provide researchers with a platform to present and discuss the application, knowledge gaps and future research directions of urban GI and how sustainable green solutions can contribute towards an integrated and sustainable urban hazard management approach. We welcome original research contributions across a series of disciplines with a hydrological, climatic, soil sciences, ecological and geomorphological focus, and encourage the submission of abstracts which demonstrate the use of GI at a wide range of scales and geographical distributions. We invite contributions focusing on (but not restricted to):
· Monitored case studies of GI, Sustainable Drainage Systems (SuDS) or Nature Based Solutions (NBS), which provide an evidence base for integration within a wider hazard management system;
· GIS and hazard mapping analyses to determine benefits, shortcomings and best management practices of urban GI implementation;
· Laboratory-, field- or GIS-based studies which examine the effectiveness or cost/benefit ratio of GI solutions in relation to their wider ecosystem potential;
· Methods for enhancing, optimising and maximising GI system potential;
· Innovative and integrated approaches or systems for issues including (but not limited to): bioretention/stormwater management; pollution control; carbon capture and storage; slope stability; urban heat exchange, and; urban food supply;
· Catchment-based approaches or city-scale studies demonstrating the opportunities of GI at multiple spatial scales;
· Rethinking urban design and sustainable and resilient recovery following crisis onset;
· Engagement and science communication of GI systems to enhance community resilience.

Water utilities and municipalities must embrace technological innovation to address the exacerbating challenges and uncertainties posed by climate change, urbanization, and population growth. The progressive transformation of urban water infrastructure and the adoption of digital solutions for water resources are opening new opportunities for the design, planning, and management of more sustainable and resilient urban water networks and human-water systems across urban scales. The “digital water” revolution is strengthening at the same time the interconnection between urban water systems (e.g., drinking water, wastewater, urban drainage) and other critical infrastructures (e.g., energy grids, transportation networks). This interconnection motivates the development of novel approaches accounting for the intrinsic complexity of such coupled systems.
This session aims to provide an active forum to discuss and exchange knowledge on state-of-the-art and emerging tools, frameworks, and methodologies for planning and management of modern urban water infrastructure, with a particular focus on digitalization and/or interconnections with other systems. Topics and applications could belong to any area of urban water demand and supply network analysis, modelling and management, including intelligent sensors and advanced metering, digital twins, asset management, decision making, novel applications of IoT, and challenges to their implementation or risk of lock-in of rigid system designs. Additional topics may include big-data analytics and information retrieval, data-driven behavioural analysis, artificial intelligence for water applications, descriptive and predictive models of water demand, experimental approaches to demand management, water demand and supply optimization, or the identification of trends and anomalies in hydraulic sensor data (e.g., for leak detection). Interesting investigations on interconnected systems can include, for example, cyber-physical security of urban water systems (i.e., communication infrastructure), combined reliability and assessment studies on urban metabolism, or minimization of flood impacts on urban networks.

The need for improved, continuous, and sustainable provision of water supply and wastewater services has exerted mounting pressures on water and wastewater supply (WWS) systems, administered by the public, private, and public-private utilities. Many of the WWS systems are currently facing major challenges like aging infrastructure, network losses, and high energy consumption, which dramatically increase operational and maintenance (O&M) costs and threaten the uninterrupted provision of services. Climate change will create additional risks to WWS systems that will need to be addressed.
To overcome the operational challenges, WWS systems are introducing novel technical approaches to improve performance and also minimize environmental impacts to the linked water sources. There are also attempts to measure and improve the technical and financial capability of WWS utilities, so that O&M costs can be covered and the system’s performance, in the long run, can be safeguarded. This may lead to tariff increases, and hence the economic impacts faced by poor households and disadvantaged groups with respect to the payment of WWS services are also explored. Although the cost of water supply and sanitation services are relatively low as compared to average household incomes, concerns have arisen on the affordability for the poorest segments of the population.
In this session, we invite contributions to different technical and socio-economic approaches and indicators that can improve the sustainability challenges of urban water systems. We are interested in original and review studies, focusing on the inter-disciplinary conceptualization of WWS and sustainability challenges by including different dimensions such as hydrology, socioeconomics, management, finance, and environment.
We invite presentations concerning soil moisture estimation, including remote sensing, field experiments, land surface modelling and data assimilation. The technique of microwave remote sensing has made much progress toward its high potential to retrieve surface soil moisture at different scales. From local to landscape scales, several field or aircraft experiments (e.g. SMAPvex) have been organised to improve our understanding of active and passive microwave soil moisture sensing, including the effects of soil roughness, vegetation, spatial heterogeneities, and topography. At continental scales, a series of several passive and active microwave space sensors, including SMMR (1978-1987), AMSR (2002-), ERS/SCAT (1992-2000) provided information on surface soil moisture. Current investigations in L-band passive microwave with SMOS (2009-) and SMAP (2015-), and in active microwave with Metop/Ascat series (2006-) and Sentinel-1, enable accurate quantification of the soil moisture at regional and global scales. Future missions, such as the CIMR Copernicus High Priority Candidate Mission, the EPS-SG Metop-SG/SCA and continuity of the Sentinel programme, will further enhance soil moisture remote sensing accuracy and spatial resolution, and they will ensure continuity of multi-scale soil moisture measurements on climate scales.
We encourage submissions related to soil moisture remote sensing, including:
- Field experiment, theoretical advances in microwave modelling and calibration/validation activities.
- High spatial resolution soil moisture estimation based on e.g. Sentinel observations, GNSS reflections, or using novel downscaling methods.
- Preparation of future missions including CIMR, Metop-SG/SCA, SMOS-High Resolution, Terrestrial Water Resources Satellite, etc.
- Root zone soil moisture retrieval and soil moisture data assimilation in land surface models, hydrological models and in Numerical Weather Prediction models.
- Evaluation and trend analysis of soil moisture climate data records such as the ESA CCI soil moisture product as well as soil moisture from re-analysis (e.g. MERRA2, ERA5, ERA5-Land).
- Inter-comparison and inter-validation between land surface models, remote sensing approaches and in-situ validation networks.
- Application of satellite soil moisture products for improving hydrological applications such as flood prediction, drought monitoring, rainfall estimation.
The socio-economic impacts associated with floods are increasing. Floods represent the most frequent and most impacting, in terms of the number of people affected, among the weather-related disasters: nearly 0.8 billion people were affected by inundations in the last decade, while the overall economic damage is estimated to be more than $300 billion. Despite this evidence, our knowledge and accurate prediction of flood dynamics remain poor, mainly related to the lack of measurements and ancillary data at the global level.
In this context, remote sensing represents a value source of data and observations that may alleviate the decline in field surveys and gauging stations, especially in remote areas and developing countries. The implementation of remotely-sensed variables (such as digital elevation model, river width, flood extent, water level, land cover, etc.) in hydraulic modelling promises to considerably improve our process understanding and prediction. During the last decades, an increasing amount of research has been undertaken to better exploit the potential of current and future satellite observations, from both government-funded and commercial missions, as well as many datasets from airborne sensors carried on airplanes and drones. In particular, in recent years, the scientific community has shown how remotely sensed variables have the potential to play a key role in the calibration and validation of hydraulic models, as well as provide a breakthrough in real-time flood monitoring applications. With the proliferation of open data and more Earth observation data than ever before, this progress is expected to increase.
We encourage presentations related to flood monitoring and mapping through remotely sensed data including:
- Remote sensing data for flood hazard and risk mapping, including commercial satellite missions as well as airborne sensors (aircraft and drones);
- Remote sensing techniques to monitor flood dynamics;
- The use of remotely sensed data for the calibration, or validation, of hydrological or hydraulic models;
- Data assimilation of remotely sensed data into hydrological and hydraulic models;
- Improvement of river discretization and monitoring based on Earth observations;
- River flow estimation from remote sensing;
- River and flood dynamics estimation from satellite (especially time lag, flow velocity, etc.)
This session concerns measurements and estimations of water levels, water extent, water storage and water discharge of water bodies such as rivers, lakes, floodplains and wetlands, and groundwater, through combined use of remote sensing and in situ measurements. Contributions that also cover aspects of assimilation of remote sensing and in situ data within hydrodynamic models are welcome and encouraged.
The monitoring of river water levels, river discharges, water bodies extent, storage in lakes and reservoirs, and floodplain dynamics plays a key role in assessing water resources, understanding surface water dynamics, characterising and mitigating water related risks and enabling integrated management of water resources and aquatic ecosystems.
While in situ measurement networks play a central role in the monitoring effort, remote sensing techniques contribute by providing near real time measurements and long homogeneous time series to study the impact of climate change, over various scales from local to regional and global.
During the past thirty years a large number of satellites and sensors has been developed and launched allowing to quantify and monitor the extent of open water bodies (passive and active microwave, optical), the water levels (radar and laser altimetry), the global water storage and its changes (variable gravity). River discharge, a key variable of hydrological dynamics, can be estimated by combining space/in situ observations and modelling, although still challenging with available spaceborne techniques. Interferometric Synthetic Aperture Radar (InSAR) is also commonly used to understand wetland connectivity, floodplain dynamics and surface water level changes, with more complex stacking processes to study the relationship between ground deformation and changes in groundwater resources.
Traditional instruments contribute to long-term water level monitoring and provide baseline databases. Scientific applications of more complex technologies like the SAR altimetry on CryoSat-2, Sentinel-3A/B and Sentinel-6 missions are maturing, including the Fully-Focused SAR technique offering very-high resolution. The future SWOT mission will open up many new hydrology-related opportunities. Preparation studies results for Sentinel-3 Next Generation and CRISTAL are encouraged.
Snow constitutes a freshwater resource for over a billion of people world-wide. High percentage of this water resource mainly come from seasonal snow located in mid-latitude regions. The current warming situation alerts that these snow water storages are in high risk to be dramatically reduced, affecting not only to water supply but also ecosystem over these areas. Therefore, understanding seasonal snow dynamics, possible changes and implication have become crucial for water resources management. Remote sensing has proven to be the main technique used to monitor the snow properties across mid-large extensions and their hydrological implications, for decades now. Moreover, the recent advances, which are focused on the study of snow properties at higher spatio-temporal scales (e.g., small-scale snow-topography interactions, snow-vegetation interaction, diurnal variation of snow, rain over snow events), are helping to understand better snow acumulation, distribution and ablation dynamics.
This session is focused on studies linking the use of remote sensing of seasonal snow in hydrological applications: techniques and data from different technologies, such as time-lapse imagery, laser scanners, radar, optical photography, thermal and hyperspectral technologies, or other new applications, with the aim of quantifying and better understanding snow characteristics (i.e. snow grain size, snow depth, albedo, pollution load, snow specific area and snow density), snow related processes (snowfall, melting, evaporation and sublimation), snow dynamics, snow hydrological impacts and snow environmental effects.

Agriculture is the largest consumer of water worldwide and at the same time irrigation is one of the sectors where there is one of the hugest differences between modern technology and the largely diffused ancient traditional practices. Improving water use efficiency in agriculture is an immediate requirement of human society for sustaining the global food security, to preserve quality and quantity of water resources and to reduce causes of poverties, migrations and conflicts among states, which depend on trans-boundary river basins. Climate changes and increasing human pressure together with traditional wasteful irrigation practices are enhancing the conflictual problems in water use also in countries traditionally rich in water. Saving irrigation water improving irrigation efficiency on large areas with modern technics is one of the first urgent action to do. It is well known in fact that agriculture uses large volumes of water with low irrigation efficiency, accounting in Europe for around 24% of the total water use, with peak of 80% in the Southern Mediterranean part and may reach the same percentage in Mediterranean non-EU countries (EEA, 2009; Zucaro 2014). North Africa region has the lowest per-capita freshwater resource availability among all Regions of the world (FAO, 2018).
Several recent researches are done on the optimization of irrigation water management to achieve precision farming using remote sensing information and ground data combined with water balance modelling.
In this session, we will focus on: the use of remote sensing data to estimate irrigation volumes and timing; management of irrigation using hydrological modeling combined with satellite data; improving irrigation water use efficiency based on remote sensing vegetation indices, hydrological modeling, satellite soil moisture or land surface temperature data; precision farming with high resolution satellite data or drones; farm and irrigation district irrigation management; improving the performance of irrigation schemes; irrigation water needs estimates from ground and satellite data; ICT tools for real-time irrigation management with remote sensing and ground data coupled with hydrological modelling.

A thorough understanding and assessment of evapotranspiration (ET) is integral to short- and long-term management decisions in agricultural, riparian, urban greenery, and forest lands. Recent advancements in remote sensing (RS), accessibility to free satellite imagery (e.g. MODIS, Landsat, Sentinel), availability of advanced platforms like Google Earth Engine (GEE), and application of the latest techniques of Artificial Intelligence (AI) have contributed to a more accurate estimation of ET at different spatial scales in various climates and eco-geographical regions for a range of green landcovers. Increasing the accessibility and resolution of RS data enables upscaling, routine updating and consistent measurements of physical properties, which would be difficult or costly to obtain from the ground. However, there is still a lot to discuss and debate about advances in development, localizing, validation and calibration of available methods, and reducing sources and magnitudes of uncertainties and biases.
At the RS-ET session, we welcome studies that estimate ET using RS-based data streams. The scope of the session will include: (1) advances in remote sensing-based ET estimation, (2) time-series and upscaling applications for a range of landcovers and spatiotemporal scales, (3) localizing available methods and their challenges, (4) validation and calibration and (5) accuracy assessment and enhancement.
Remote sensing techniques are widely used to monitor the relationship between the water cycle and vegetation dynamics and its impact on the carbon and energy cycles. Measurements of vegetation water content, transpiration and water stress contribute to a better global understanding of the water movement in the soil-plant system. This is critical for the detection and monitoring of droughts and their impact on biomass, productivity and feedback on water, carbon and energy cycles. With the number of applications and (planned) missions increasing, this session aims to bring researchers together to discuss the current state and novel findings in the remote observation of the interactions between vegetation and hydrology. We aim to (1) discuss novel research and findings, (2) exchange views on what should be done to push the field forward, and (3) identify current major challenges.
We encourage authors to submit presentations on:
• Remote sensing data analyses,
• Modelling studies,
• New hypothesis,
• Enlightening opinions.

Remote sensing products have a high potential to contribute to monitoring and modelling of water resources. Nevertheless, their use by water managers is still limited due to lack of quality, resolution, thrust, accessibility, or experience.
In this session, we look for new developments that support the use of remote sensing data for water management applications from local to global scales. We are looking for research to increase the quality of remote sensing products, such as higher resolution mapping of land use and/or agricultural practices or improved assessments of river discharge, lake and reservoir volumes and groundwater resources. We are interested in quality assessment of remote sensing products through uncertainty analysis or evaluations using alternative sources of data. We also welcome contributions using a combination of different techniques (physically based models or artificial intelligence or techniques) or a combination of different sources of data (remote sensing and in situ). Finally, we wish to attract presentations on developments of user-friendly platforms providing smooth access to remote sensing data for water applications.
We are particularly interested in applications of remote sensing to estimate the human water interactions such as dam operations and/or irrigations.

The water cycle or hydrological cycle involves the continuous movement of water on, above, and below the surface of the Earth. In general, hydrological cycle components (e.g., precipitation, evaporation, water storage, and runoff) are characterized by large temporal and spatial variability. Accurate monitoring of various hydrological cycle components and developing hydrological models are important for improving our understanding of hydrological processes. With significant development of sensor technology and sharply growing platforms in past decades, remote sensing offers enhanced capability to monitor various hydrological cycle components at different temporal and spatial scales to complement conventional in situ measurements. Considerable efforts have been made to explore the potentials of remotely sensed data from a vast range of different platforms (e.g., satellite, airborne, drone, ground-based radar) and sensors (e.g., optical, infrared, microwave) in advancing hydrology research, particularly in poorly gauged and ungauged regions. The application of remote sensing in hydrology is expected to increase with enhanced recognition of its potentials and continuous development of advanced sensors (e.g., new satellite missions) and retrieval methods (e.g., innovative machine learning and data assimilation techniques).
The session aims to present and discuss recent advances in the remote sensing of hydrological cycle components as well as the application of remote sensing in hydrological modeling. We encourage studies to investigate the performance of remotely sensed data in multi-variable calibration and spatial evaluation of hydrological models. The added-value of spatially downscaling remotely sensed data in improving hydrological modelling is also particularly welcome.
The Tibetan Plateau and surrounding mountain regions, known as the Third Pole, cover an area of > 5 million km2 and are considered to be the water tower of Asia. The Pan Third Pole expands on both the north-south and the east-west directions, going across the Tibetan Plateau, Pamir, Hindu Kush, Iran Plateau, Caucasian and Carpathian, and covering an area of about 20 million km2. Like the Arctic and Antarctica, the Pan Third Pole’s environment is extremely sensitive to global climate change. In recent years, scientists from around the globe have increased observational, remote sensing and numerical modeling research related to the Pan Third Pole in an effort to quantify and predict past, current and future scenarios. Co-sponsored by TPE (www.tpe.ac.cn), this session is dedicated to studies of Pan Third Pole atmosphere, cryosphere, hydrosphere, and biosphere and their interactions with global change. Related contributions are welcomed.

Rainfall is a “collective” phenomenon emerging from numerous drops. Understanding the relation between the physics of individual drops and that of a population of drops remains an open challenge, both scientifically and at the level of practical implications. This remains true also for solid precipitation. Hence, it is much needed to better understand small scale spatio-temporal precipitation variability, which is a key driving force of the hydrological response, especially in highly heterogeneous areas (mountains, cities). This hydrological response at the catchment scale is the result of the interplay between the space-time variability of precipitation, the catchment geomorphological / pedological / ecological characteristics and antecedent hydrological conditions. Therefore, (1) accurate measurement and prediction of the spatial and temporal distribution of precipitation over a catchment and (2) the efficient and appropriate description of the catchment properties are important issues in hydrology.
This session will bring together scientists and practitioners who aim to measure and understand precipitation variability from drop scale to catchment scale as well as its hydrological consequences. Contributions addressing one or several of the following topics are especially targeted:
- Novel techniques for measuring liquid and solid precipitation variability at hydrologically relevant space and time scales (from drop to catchment scale), from in situ measurements to remote sensing techniques, and from ground-based devices to spaceborne platforms. Innovative comparison metrics are welcomed;
- Precipitation drop (or particle) size distribution and its small scale variability, including its consequences for precipitation rate retrieval algorithms for radars, commercial microwave links and other remote sensors;
- Novel modelling or characterization tools of precipitation variability from drop scale to catchment scale from various approaches (e.g. scaling, (multi-)fractal, statistic, deterministic, numerical modelling);
- Novel approaches to better identify, understand and simulate the dominant microphysical processes at work in liquid and solid precipitation.
- Applications of measured and/or modelled precipitation fields in catchment hydrological models for the purpose of process understanding or predicting hydrological response.

Water resources managers and scientists are facing several challenges when applying climate models for hydrological variables. Indeed, a gap exists between what is provided by climate scenarios and what is needed and useful for water resources managers. In order to reduce this gap and enhance the assessment of climate change impacts, we need to improve our understanding, knowledge and model representations of the interactions between climate drivers and hydrological processes at the regional scale. This is essential to outline forecasts and assess extreme events risk, where uncertainty, probabilistic approaches ad prediction scenarios should be properly defined.
This session particularly welcomes, but is not limited to, contributions on:
- Advanced techniques to simulate and predict hydrological processes and water resources, with emphasis on stochastic and hybrid methods.
- Advanced techniques to simulate and predict hydroclimatic extreme events including compound extreme events relevant to water resources management (e.g. heatwaves and droughts).
- Holistic approaches to generate future water resources scenarios integrating also anthropogenic and environmental perspectives.
- Hydroclimatic change attribution studies using probabilistic approaches and novel causality frameworks with uncertainty assessment.
- Evaluation of climate models performance at the regional scale using observational data
This session is sponsored by the International Association of Hydrological Sciences (IAHS) and the World Meteorological Organization – Commission for Hydrology (WMO CHy) and it is also related to the scientific decade 2013–2022 of IAHS, entitled “Panta Rhei - Everything Flows”.
Extreme hydro-meteorological events drive many hydrologic and geomorphic hazards, such as floods, landslides and debris flows, which pose a significant threat to modern societies on a global scale. The continuous increase of population and urban settlements in hazard-prone areas in combination with evidence of changes in extreme weather events lead to a continuous increase in the risk associated with weather-induced hazards. To improve resilience and to design more effective mitigation strategies, we need to better understand the aspects of vulnerability, risk, and triggers that are associated with these hazards.
This session aims at gathering contributions dealing with various hydro-meteorological hazards that address the aspects of vulnerability analysis, risk estimation, impact assessment, mitigation policies and communication strategies. Specifically, we aim to collect contributions from academia, the industry (e.g. insurance) and government agencies (e.g. civil protection) that will help identify the latest developments and ways forward for increasing the resilience of communities at local, regional and national scales, and proposals for improving the interaction between different entities and sciences.
Contributions focusing on, but not limited to, novel developments and findings on the following topics are particularly encouraged:
- Physical and social vulnerability analysis and impact assessment of hydro-meteorological hazards
- Advances in the estimation of socioeconomic risk from hydro-meteorological hazards
- Characteristics of weather and precipitation patterns leading to high-impact events
- Relationship between weather and precipitation patterns and socio-economic impacts
- Hazard mitigation procedures
- Strategies for increasing public awareness, preparedness, and self-protective response

Urban hydrological processes are characterized by high spatial variability and short response times resulting from a high degree of imperviousness. Therefore, urban catchments are especially sensitive to space-time variability of precipitation at small scales. High-resolution precipitation measurements in cities are crucial to properly describe and analyses urban hydrological responses. At the same time, urban landscapes pose specific challenges to obtaining representative precipitation and hydrological observations.
This session focuses on high-resolution precipitation and hydrological measurements in cities and on approaches to improve modeling of urban hydrological response, including:
- Novel techniques for high-resolution precipitation measurement in cities and for multi-sensor data merging to improve the representation of urban precipitation fields.
- Novel approaches to hydrological field measurements in cities, including data obtained from citizen observatories.
- Precipitation modeling for urban applications, including convective permitting models and stochastic rainfall generators.
- Novel approaches to modeling urban catchment properties and hydrological response, from physics-based, conceptual and data-driven models to stochastic and statistical conceptualization.
- Applications of measured precipitation fields to urban hydrological models to improve hydrological prediction at different time horizons to ultimately enable improved management of urban drainage systems (including catchment strategy development, flood forecasting and management, real-time control, and proactive protection strategies aimed at preventing flooding and pollution).
- Strategies to deal with upcoming challenges, including climate change and rapid urbanization.

Hydro-meteorological extremes such as floods, droughts, storms, or heatwaves often affect large regions therefore causing large damages and costs. Hazard and risk assessments, aiming at reducing the negative consequences of such extreme events, are often performed with a focus on one location despite the spatially compounding nature of extreme events. While spatial extremes receive a lot of attention by the media, little is known about their driving factors and it remains challenging to assess their risk by modelling approaches. Key challenges in advancing our understanding of spatial extremes and in developing new modeling approaches include the definition of multivariate events, the quantification of spatial dependence, the dealing with large dimensions, the introduction of flexible dependence structures, the estimation of their probability of occurrence, the identification of potential drivers for spatial dependence, and linking different spatial scales. This session invites contributions which help to better understand processes governing spatial extremes and/or propose new ways of describing and modeling spatially compounding events at different spatial scales.

Over the last decades, a significant body of empirical and theoretical work has revealed the departure of statistical properties of hydrometeorological processes from the classical statistical prototype, as well as the scaling behaviour of their variables in general, and extremes in particular, in either state, space and/or time. In the meantime, extremes and more generally the statistics of hydrometeorologic processes are the key input for hydrological applications. As a classic example the estimation of design rainfall should be mentioned. Beside the estimation of the absolute rainfall amount related to a certain return period, the intra-event rainfall distribution, its spatial extension and the rainfall intensities at neighbouring stations can be required, depending on the intended application and thus the analysed scale. But design rainfall is only one among numerous hydrologic applications, which shape the framework for this session.
The estimation of the hydrometeorological extremes and probability distribution, the identification and involvement of supporting information and the hydrologic application over wide range of scales are open challenges, especially under non-stationary conditions. On the other side, hydrometeorologists had never access to so much computer power and data to face these open challenges.
This session welcomes, but is not limited to submissions on:
- Coupling stochastic approaches with deterministic hydrometeorological predictions, in order to better represent predictive uncertainty
- Development of robust statistics under non-stationary conditions for dimensioning purposes
- Development of parsimonious representations of probability distributions of hydrometeorological extremes over a wide range of scales in risk analysis applications and hazard prediction
- Improvements for reliable estimation of extremes with high return periods under consideration of upper or lower limits due to physical constraints
- Linking underlying physics and stochastics of hydrometeorologic extremes
- Exploration of supporting data sets for additional stochastic information (e.g. unintended use of other measurements, citizen scientist data, soft data, …)
An overall aim of the session is to bridge the gap between the theoretical stochastic analysis of hydrometeorological processes and its practical hydrological application.

Traditionally, hydrologists focus on the partitioning of precipitation water on the surface, into evaporation and runoff, with these fluxes being the input to their hydrologic models. However, more than half of the evaporation globally comes back as precipitation on land, ignoring an important feedback of the water cycle if the previous focus applied. Land-use and water-use changes, as well as climate variability and change alter, not only, the partitioning of water but also the atmospheric input of water as precipitation, related with this feedback, at both remote and local scales.
This session aims to:
i. investigate the remote and local atmospheric feedbacks from human interventions such as greenhouse gasses, irrigation, deforestation, and reservoirs on the water cycle, precipitation and climate, based on observations and coupled modelling approaches,
ii. investigate the use of hydroclimatic frameworks such as the Budyko framework to understand the human and climate effects on both atmospheric water input and partitioning,
iii. explore the implications of atmospheric feedbacks on the hydrologic cycle for land and water management.
Typically, studies in this session are applied studies using fundamental characteristics of the atmospheric branch of the hydrologic cycle on different scales. These fundamentals include, but are not limited to, atmospheric circulation, humidity, hydroclimate frameworks, residence times, recycling ratios, sources and sinks of atmospheric moisture, energy balance and climatic extremes. Studies may also evaluate different sources of data for atmospheric hydrology and implications for inter-comparison and meta-analysis. For example, observations networks, isotopic studies, conceptual models, Budyko-based hydro climatological assessments, back-trajectories, reanalysis and fully coupled earth system model simulations.

Development and application of decision support systems to enhance sustainable feedbacks between anthropogenic activities and the natural functioning of aquifers and underground reservoirs requires reliable methods to infer key parameters controlling multiphase flow and contaminant fluxes of conservative or reactive chemicals in subsurface environments. These systems are complex and extremely heterogeneous exhibiting variations on a multiplicity of scales.
Addressing heterogeneity in all its manifestations is the focus of exciting and intense forefront scientific research and industrial activities.
This session:
- invites presentations on recent developments in understanding, measuring, and modelling subsurface flow and solute transport processes in both the saturated and unsaturated zones, as well as across boundaries between these;
- is aimed at providing an opportunity for specialists to exchange information and to introduce various existing and novel alternative deterministic and stochastic models of subsurface flow and transport to the general hydrological community, with critical and timely applications to environmentally and industrially relevant scenarios.
Focus is placed on recent key developments in novel theoretical aspects and associated computational tools, fate of new contaminants, and field/laboratory applications dealing with accurate and efficient prediction and quantification of uncertainty for flow, conservative and reactive transport processes in the subsurface, in the presence of multiple information at different scales, ranging from the pore level to the intermediate and basin scales.

Dissolution, precipitation, and chemical reactions between infiltrating fluid and rock matrix alter the composition and structure of the rock, either creating or destroying flow paths. Strong, nonlinear couplings between the chemical reactions at mineral surfaces and fluid motion in the pores often leads to the formation of intricate patterns: networks of caves and sinkholes in karst area, wormholes induced by the acidization of petroleum wells, porous channels created during the ascent of magma through peridotite rocks. Dissolution and precipitation processes are also relevant in many industrial applications: dissolution of carbonate rocks by CO2-saturated water can reduce the efficiency of CO2 sequestration, mineral scaling reduces the effectiveness of heat extraction from thermal reservoirs, acid rain degrades carbonate-stone monuments and building materials.
With the advent of modern experimental techniques, these processes can now be studied at the microscale, with direct visualization of the evolving pore geometry. On the other hand, the increase of computational power and algorithmic improvements now make it possible to simulate laboratory-scale flows while still resolving the flow and transport processes at the pore-scale.
We invite contributions that seek a deeper understanding of reactive flow processes through interdisciplinary work combining experiments or field observations with theoretical or computational modeling. We seek submissions covering a wide range of spatial and temporal scales: from table-top experiments and pore-scale numerical models to the hydrological and geomorphological modelling at the field scale. We also invite contributions from related fields, including the processes involving coupling of the flow with phase transitions (evaporation, sublimation, melting and solidification).

A number of physical (e.g. flow and transport), chemical (e.g. red-ox reactions) and biological (e.g. bio-mineralization) mechanisms critically control the fate of the underground environment where rocks, liquids, gases and microbes sit in close proximity and interaction. The common feature of these processes is their heterogeneity (spatial variability) and their temporal dynamics at which they impact the natural environment. A wide range of innovative methods have recently emerged that provide vision into the coupled processes at spatial and temporal scales unexplored before, including: 4D geophysical methods, near-real time biochemical and isotopic monitoring, smart sensors and observation systems, remote sensing, citizen science observations, microscopic imaging technics, pore to global scale numerical models, data-driven machine learning and hybrid modeling approaches.
The session seeks contributions that present (i) technological innovations in experimental and sensing methods for the observation of physical and biochemical processes occurring in the subsurface; (ii) advances in computational methods that help extracting knowledge from datasets integrating time, space and scientific disciplines; and, (iii) improvements of modeling technics for the description of coupled physical and biochemical processes from the micro to the kilometer scales. Reviews and general discussions on current technological and observation challenges are also highly encouraged.

Particles (inorganic particles, biocolloids, plastics) in environmental systems are of great concern because of their potential adverse effects on ecosystem functions, wildlife and human health. They may also alter the transport properties of dissolved contaminants and change the hydraulic properties of subsurface systems. On the other hand, engineered particles and biocolloids play an important role in site remediation and aquifer restoration. This interdisciplinary session fosters the exchange among scientists from hydrogeology, microbiology, ecotoxicology, engineering, and analytical chemistry in order to provide a general picture of the occurrence and fate of natural and engineered particles in aquatic and terrestrial systems.
We are expecting contributions in the following fields:
• occurrence, fate and transport of biocolloids, nanoparticles and other particles (microplastics, soot, ...) in aquatic and terrestrial systems
• methods to detect, characterize, and quantify particles in
aquatic and terrestrial systems
• advanced experimental methods to test the behaviour of particles in aquatic and terrestrial systems (mesocosms, non-invasive imaging, ...)
• interactions between biocolloids, particles and solid surfaces
• biocolloid biodegradation in the presence of solids
• toxicity of products generated from biological disruption of pollutants in the presence of biocolloids
• adverse effects of nanoparticles on microorganisms
• effects of climate change on biocolloid and nanoparticle migration
• public health risks associated with water and air polluted with biocolloids and nanoparticles.

This session deals with the use of geophysical methods for the characterization of subsurface properties, states, and processes in contexts such as hydrology, agriculture, contaminant transport, etc. Geophysical methods potentially provide subsurface data with an unprecedented high spatial and temporal resolution in a non-invasive manner. However, the interpretation of these measurements is far from straightforward in many contexts and various challenges remain. Among these are the need for improved quantitative use of geophysical measurements in model conceptualization and parameterization, and the need to move quantitative hydrogeophysical investigations beyond the laboratory and field scale towards the catchment scale. Therefore, we welcome submissions addressing advances in the acquisition, processing, analysis and interpretation of data obtained from geophysical and other minimally invasive methods applied to a (contaminant) hydrological context. In particular, we encourage contributions on innovations in experimental and numerical methods in support of model-data fusion, including new concepts for coupled and joint inversion, and improving our petrophysical understanding on the link between hydrological and geophysical properties.

Climate change is one of the most important challenges humankind faces today. Groundwater has been an important buffer against climate variability for millennia, providing a secure water supply globally. Despite the important potential role of groundwater storage in climate change adaptation strategies, this role and the actual impact of climate change on groundwater resources remain highly uncertain. The pathways through which changes in natural (e.g., evaporation, transpiration and rainfall) and human factors (e.g., groundwater abstractions, water management strategies) impact groundwater resources are only partially understood due to the complexity and the many (unknown) feedback mechanisms of the atmosphere-land-subsurface system, including humans as an agent. Therefore, this session focuses on: How are different groundwater-related processes affected by climate change, and how do they impact groundwater resources? How to implement climate change in our groundwater studies to predict its impact? How to design and assess potential (ground)water management strategies to increase resilience?
We are inviting presentations taking up these challenges and with a particular interest in process-based analysis and models. We especially encourage (but do not limit to) contributions on the following topics:
Impact of climate change:
- on groundwater recharge (e.g. through changes in rainfall, evaporation, transpiration, etc.).
- on salinity and water availability in coastal aquifers due to sea-level changes and dilution.
- on groundwater extremes (both droughts and high groundwater levels).
- on changes in dilution potential or leaching potential for contaminants, including pesticides and nutrients.
Human impacts on and management of groundwater resources under a changing climate:
- Impacts of groundwater abstractions, land-use changes, river regulation
- Groundwater-surface water management strategies
Feedback between groundwater and climate through coupled models:
- Methodologies showcasing how to implement climate change into subsurface models, including uncertainties of the projections.
- Comparative studies using different approaches/models to study climate change impacts.
This session is co-organized by the Commission on Groundwater and Climate Change (CGCC) of the IAH.
The proper management of blue and green water is vital for sustainable livelihoods in drylands (i.e. hyper—arid, arid, semi—arid and dry sub—humid lands), where any productive activity is structurally and deeply related to the understanding of soil hydrological behaviour. In these areas groundwater is usually the primary source for drinking water supply and irrigation so that water management is critical to the water-food-energy security nexus.
Irrigation, in particular, should be regarded as a fundamental element of any agroecosystem and an effective defence against desertification. This as a consequence of the fact that on one hand traditional irrigation is often a cultural heritage, which requires to be faced with an interdisciplinary approach, while on the other hand incorrect irrigation techniques may lead to soil and groundwater salinization, with dramatic fallout on agricultural productivity.
Also, due to local shifts in climate and in the hydrological cycle, or global changes such as population growth and changes in land use, drylands and regions with high water stress are expected to expand globally: for example, catchments in Central Europe with continental climate and decreasing precipitation in summer periods are likely to be new areas subjected to water stress.
This session welcomes contributions ranging from the understanding of the soil hydrological behaviour and of the mass fluxes through the soil in drylands and environments under stress conditions to the identification of the consequences of a changing environment for better future management, protection, and sustainable use of water resources in drylands.
This includes adapted modelling techniques coupling climate models with hydrological models or with soil water and groundwater models, or studies dealing with groundwater quantity and quality, the interaction between irrigation and soil hydrology, and the design of irrigation systems in arid districts and oases, also involving non—conventional waters (e.g. water harvesting). Particular attention will be given to traditional irrigation techniques as well as to precision irrigation techniques, also with local community involvement.
Due to a frequently associated data scarcity issue in dry regions, methodologies and strategies addressing uncertainty and limited data availability are of interest for this session. Interdisciplinary contributions and contributions from appropriate field observational studies are encouraged as well.

The session aims to bring together scientists studying various aspects related to groundwater flow systems, and their role in solving water management and environmental problems.
Understanding groundwater flow systems requires knowledge of the governing processes and conditions from the local to regional and basin-scales, including porous and fractured porous media. Moreover, problems connected to groundwater management underline the importance of sustainable development and protection of groundwater resources.
In this context of groundwater flow understanding, the session intends to analyze issues connected to groundwater management and its protection from degradation with respect to quantity and quality (e.g. due to over-exploitation, conflicts in use, climate change, resource development or contamination). Papers related to methods of characterizing groundwater flow systems, and preventing, controlling and mitigating harmful environmental impacts related to groundwater, including those in developing countries, are also welcome.

Karst environments are characterized by distinctive landforms and unique hydrological behaviors. Karst systems are extremely complex, heterogeneous and very difficult to manage, because their formation and evolution are controlled by a wide range of geological, hydrological, geochemical and biological processes, and are extremely variable in time and space. Furthermore, karst systems are highly vulnerable to a variety of hazards, due to the direct connection between the surface and subsurface through the complex networks of conduits and caves.
In karst, any interference is likely to have irreversible impacts and disturb the natural balance of the elements and processes. The great variability and unique connectivity may result in serious engineering problems: on one hand, karst groundwater resources are easily contaminated by pollution because of the rapidity of transmission through conduit flow, and remediation action, when possible, could be very expensive and require a long time; on the other hand, the presence of karst conduits that weakens the strength of the rock mass may lead to serious natural and human-induced hazards. The design and development of engineering projects in karst environments thus should necessarily require: 1) an enhanced understanding of the natural processes governing the initiation and evolution of karst systems through both field and modelling approaches, and 2) specific interdisciplinary approaches aimed at mitigating the detrimental effects of hazardous processes and environmental problems.
This session calls for abstracts on research from karst areas worldwide related to geomorphology, hydrogeology, engineering geology, hazard mitigation in karst environments in the context of climate change and increasing human disturbance.

This session combines presentations on recent developments in understanding, measuring, and modeling subsurface flow and transport. We aim to include processes in both the saturated and unsaturated zones, as well as across boundaries at different scales. At the same time, we address unsolved problems related groundwater contamination management as risk assessment and remediation.
The correct quantification of transport processes, which occur at different spatial and temporal scales, is challenging. It strongly influences predicted spreading, dilution and mixing rates. However, dispersion, mixing and chemical reactions are local phenomena that strongly depend on the interplay between large-scale system heterogeneity and smaller-scale processes. Much effort has been placed in the fundamental understanding of these processes since they are of practical relevance to identify the fate of contaminants in surface and subsurface water that can affect human health and the environment. Particularly newly emerging contaminants of such as PFASs, pharmaceuticals, pesticides, or nanoparticles are increasingly being detected at low levels in surface- and groundwater. Some of these anthropogenic chemicals are potentially harmful can produce long-term adverse health effects even at very low levels of exposure.
The aim of this session is to discuss the effect of flow heterogeneity on transport at different scales, from pore scale up to catchment scale - including theory, modeling, laboratory and field experiments as well as applications. Our contributions deal with the questions: Is macrodispersivity a meaningful parameter? Under which conditions does spatially variable flow enhance mixing and chemical reactions? What is the role played by diffusive processes in modeling transport in porous media? How to upscale dispersion and reactive transport from pore to field-scale? What is the relation between ADE models and dynamic structures of catchment hydrology like travel time distributions? What are appropriate methods to characterize the relevant aquifer properties? What are the recent improvements in transport measurement technologies? What is the best way to physically and chemically characterize sites contaminated by anthropogenic chemicals? What is their mobility and persistence in both the unsaturated and unsaturated zones? How can we improve remediation through laboratory and field research?

Pressure in water resources is increasing rapidly as a result of climate change and the growing population. In this context, urban groundwater plays an essential role as a strategic resource for the development of cities and must be preserved. However, a wide variety of human/urban related activities modify the physico-chemical conditions of urban aquifers, among others:
• The release of chemicals from sources such as wastewater (throught direct discharges or leaky sewers) and urban runoff
• The introduction of contaminants of emerging concern such as pharmaceuticals, personal care products, illicit drugs…
• The introduction of industrial compounds such as chlorinated solvents, perfluorinated compounds,…
• The interaction with underground constructions
• The alteration of baseflow and surface water quality
• The modification of transit times
• The use of shallow aquifers for geothermal energy
• The increase of urbanized areas and sealed surfaces
• The alteration of the fresh-salt water interface in coastal aquifers (i.e., saltwater intrusion)
Accordingly, it is of paramount importance to assess qualitatively and quantitatively the aspects that may alter the physico-chemical conditions of urban aquifers and develop methods for preserving them.
This session welcomes contributions (laboratory and pilot-scale experiments, case studies, numerical investigations, etc) focused on urban groundwater resources.
During the last decades we have seen an exponential increase in new anthropogenic chemicals such as pharmaceuticals, personal care and household products, industrial or agricultural chemicals etc. Some of these of chemicals are potentially harmful and persistent in the environment and they are increasingly being detected at low levels in surface- and groundwater. Many such emerging contaminants (e.g. PFASs, pharmaceuticals, pesticides, nanoparticles etc) may demonstrate low acute toxicity, but can still produce long-term adverse health effects even at very low levels of exposure. These chemicals have produced many additional challenges for groundwater management, risk assessment and remediation. Questions related to the mobility, persistence and potential transformation or degradation of emerging contaminants in both the saturated and unsaturated zones have to be addressed. Additional challenges may include interactions or competition between different chemicals and/or natural constituents such as colloids and organic matter, cocktail effects and the capability of existing models, developed for traditional contaminants, to make reliable predictions of ultra-low concentrations. The questions of how best to physically and chemically characterize sites contaminated by this class of contaminants also have to be visited. For traditional contaminants challenges may also remain to meet cleanup goals due to a multiplicity of factors that include geologic heterogeneity, unknown sources, and knowledge gaps in the understanding of complex reactive processes, specifically with chemical mixtures.
This session seeks papers on process understanding through laboratory and field research, modeling, and site characterization to address new challenges and solutions associated with groundwater contamination from emerging contaminants as well as unsolved challenges related to traditional contaminants.
Groundwater salinization in the Mediterranean is a phenomenon of increasing relevance and a focus area of subsurface water quality studies. Still, several recent reviews of the topic have identified that there still is a lack of studies addressing the temporal variations and spatial variations in groundwater and salinization in coastal aquifers in three dimensions. The session aims at exploring the dynamics of groundwater salinization. We invite contributions addressing temporal variations at all time scales and spatial or even combined spatial-temporal dynamics. Experimental data, projections, and reconstructions are needed showing variations of salinization at different time scales, from seasonal to historical and paleo-hydrological, e.g., by using residence time analysis combined with salinization indicators or modeling techniques. Hopefully, examples of receding salinization trends due to remediation or management actions can also be presented to show the dynamics of reverted salinization. We welcome high-resolution or long-time series of groundwater salinization related to tidal effects, pumping, or changing external driving forces that provide a better understanding of the dynamics of salinization. There is also an interest in spatial dynamics of the extent and development of transition zones between salt and fresh water. Contributions with various methodological approaches such as geophysics, geochemistry, environmental isotopes, remote sensing, multi-parameter monitoring, and combined approaches will be considered.
We aim at synthesizing and fostering a better understanding of common principles in the dynamics of the progression or recession of groundwater salinization.

Data-driven models are increasingly used to solve groundwater problems. These types of models require less knowledge about the subsurface and depend more on the input and output data. The focus is typically on groundwater level time series, with the goal to obtain as much information as possible from these measurements. Models can, for example, be used to predict future groundwater levels, determine the effect of a pumping station, or analyze data to support more traditional groundwater modeling methods. In this session, we seek contributions on the development of new and improved data-driven methods to model groundwater level time series, as well as applications and comparative studies of existing methods to solve groundwater problems. Data-driven models include, but are not limited to, time series models, machine learning models, and conceptual 1D groundwater models. Contributions are also sought on typical challenges that arise when modeling groundwater time series, such as non-stationary time series, irregular time steps, and regionalization of model results to the scale of an aquifer.
Vadose zone hydrology studies the physical processes in the unsaturated zone. Modeling and observation of soil and vadose zone processes aims at characterizing soil properties and quantifying terrestrial water storage dynamics. The states of soil, air and water affect biogeochemical processes, vegetation water availability, nutrient and pollutant transport at local scale, catchment response functions and rainfall-runoff processes at intermediate scale, land-atmosphere interaction and land-climate feedbacks at the continental scale. Advanced measurement techniques, increased availability of high-frequency data, and the need for terrestrial system understanding challenges vadoze zone modeling concepts, budging model parameterizations from static to near dynamic. This session aims to bring together scientists advancing the current status in modelling soil and vadose zone processes from the pore to the catchment and continental scale. Contributions to this session address soil hydrological processes, characterization of soil properties and soil hydraulic properties, soil biogeochemical processes and their interactions with hydrology, transport of pollutants, and soil vegetation atmosphere modelling.

The characterization of unsaturated flow is important e.g. for understanding the impact of climate change on water availability and groundwater resources, or the effects of droughts on ecosystem functions and agricultural productivity. Moreover, an adequate description of water flow in the unsaturated zone is required for evaluating the fate of pollutants in the earth critical zone to minimize possible threats to groundwater resources. Water flow characterization is often challenging due to subsurface heterogeneity, strong non-linearity within and between processes and the contribution of preferential flow paths. The latter may result from macro-pore networks (such as fractures, plant root or earth worm channels), so that water and pollutants can bypass most of the matrix and thus enable a fast water flow and contaminant transport in unsaturated zone. This session aims at illustrating and discussing current research of flow processes within the unsaturated zone, including field studies and experiments as well as modeling approaches and simulation studies. More specifically, we encourage researchers to participate with contributions among the following topics:
-) Monitoring of flow and transport in the unsaturated zone, from field and lysimeter studies to pore scale observations
-) Measuring and modeling of environmental tracers, including stable water isotopes, for characterizing subsurface flow processes at different spatial and temporal scales
-) Geophysical investigations for determining structures and mechanisms that can induce preferential flow and transport in different dimensions
-) Identification and quantification of water and solute transport processes, especially in the context of changing climate conditions that alter bio-geochemical processes
-) Investigating the influence of plant growth on preferential flow and transport (e.g. investigation of root water uptake dynamics or evapotranspiration patterns)
-) Development of new modeling approaches for describing unsaturated flow and reactive transport, given a restricted availability of field measurements and observations; e.g. in the context of tools for decision support
-) Sensitivity and uncertainty analyses related to the characterization of subsurface flow and both conservative and reactive transport

The interactions between plants and the environment play a prominent role in terrestrial fluxes and biochemical cycles, but we still lack a general understanding of how these interactions impact plant growth and plant access to soil resources particularly under deficient conditions. The main challenge arises from the complexity of both soil and plants. To address such a knowledge gap, an improved understanding and predictability of plant-related transfer processes are urgently needed.
Emerging experimental techniques such as non-invasive imaging techniques and system modeling tools have deepened our insights into the functioning of water and solute transport processes in the soil-plant system. Quantitative approaches that integrate across disciplines and scales constitute stepping stones to foster our understanding of fundamental biophysical processes at the frontier of soil and plants.
This session targets researchers investigating plant-related resource transfer processes across different scales (from the rhizosphere to the global scale) and welcomes scientists from multiple disciplines ranging from soil to plant sciences. We are specifically inviting contributions of:
- Measuring and modeling of water and solute fluxes across soil-plant-atmosphere continuum at different scales.
- Novel experimental and modeling techniques assessing below-ground plant processes such as root growth, root water and nutrient uptake, root exudation, microbial interactions and soil aggregation
- Measuring and modeling of soil-plant hydraulics
- Bridging the knowledge gap between biologically and physically oriented research in soil and plant sciences
- Identification of plant strategies to better access and use resources from soil under abiotic stress
- Mechanistic understanding of drought impact on transpiration and photosynthesis and their predictions by earth system model
Obtaining quantitative information on the spatial pattern of soil redistribution during storms and on the spatial sources supplying sediment to rivers is required to improve our understanding of the processes controlling these transfers and to design effective control measures. It is also crucial to quantify the transfer or the residence times of material transiting rivers along the sediment cascade, and to reconstruct the potential changes in sources that may have occurred at various temporal scales. During the last few decades, several sediment tracing or fingerprinting techniques have contributed to provide this information, in association with other methods (including soil erosion modelling and sediment budgeting). However, their widespread application is limited by several challenges that the community should address as priorities.
We invite specific contributions to this session that address any aspects of the following:
• Developments of innovative field measurement and sediment sampling techniques;
• Soil and sediment tracing techniques for quantifying soil erosion and redistribution;
• Sediment source tracing or fingerprinting studies, using conventional (e.g. elemental/isotopic geochemistry, fallout radionuclides, organic matter) or alternative (e.g. colour, infrared, particle morphometry) approaches;
• Investigations of the current limitations associated with sediment tracing studies (e.g. tracer conservativeness, uncertainty analysis, particle size and organic matter corrections);
• Applications of radioisotope tracers to quantify sediment transit times over a broad range of timescales (from the flood to the century);
• The association of conventional techniques with remote sensing and emerging technologies (e.g. LiDAR);
• Integrated approaches to developing catchment sediment budgets: linking different measurement techniques and/or models to understand sediment delivery processes.
The transfer of sediments and associated contaminants play an important role in catchment ecosystems as they directly influence water quality, habitat conditions and biogeochemical cycles. Contaminants may include heavy metals, pesticides, nutrients, radionuclides, and various organic, as well as organometallic compounds. The environmental risk posed by sediment-bound contaminants is largely determined by the sources and rate at which sediments are delivered to surface water bodies, the residence time in catchments, lakes and river systems as well as biogeochemical transformation processes. However, the dynamics of sediment and contaminant redistribution is highly variable in space and time due to the complex non-linear processes involved. This session thus focuses on sources, transport pathways, storage and re-mobilization, and travel times of sediments and contaminants across temporal and spatial scales as well as their impact on catchment and freshwater ecosystems.
This session particularly addresses the following issues:
- Delivery rates of sediments and contaminants from various sources (i.e. agriculture, urban areas, mining, industry or natural areas);
- Transport, retention and remobilization of sediments and contaminants in catchments and river reaches;
- Modelling of sediment and contaminant transport on various temporal and spatial scales;
- Biogeochemical controls on contaminant transport and transformation;
- Studies on sedimentary processes and morphodynamics, particularly sediment budgets;
- Linkages between catchment systems and lakes, including reservoirs;
- Analysis of sediment archives to appraise landscape scale variations in sediment and contaminant yield over medium to long time-scales;
- Impacts of sediments and contaminants on floodplain, riparian, hyporheic and other in-stream ecosystems;
- Response of sediment and contaminant dynamics in catchments, lakes and rivers to changing boundary conditions and human actions.

Sedimentary processes in aquatic environments, including erosion, transport, and deposition of sediment by hydrodynamic mechanisms, are key features for various research disciplines, e.g., geomorphology and paleoclimatology or hydraulics, river engineering and water resources management and hydrology. Accurate quantification of erosion, transport, and deposition rates, conditioning river channel morphology, and bed composition, is fundamental for adequate development of conceptual sediment budget models and for the calibration and validation of the numerical tools.
The main goal of this session is to bring together the community of scientists, scholars, and engineers, investigating, teaching, and applying novel measurement techniques and monitoring concepts, which are crucial in determining sedimentary and hydro-morphological processes in rivers, lakes, and reservoirs, estuaries as well as in coastal and maritime environments. It focuses on the quantification of bedload and suspended load, bedforms migration, channel horizontal migration, bed armoring and colmation, but also the transport mode, flocculation, settling, and re-suspension of the sediment particles.
Contributions are welcome with a particular focus on single and combined measurement techniques, post-processing methods as well as on innovative and advanced monitoring concepts for field and laboratory applications. We welcome contributions containing recent results in a temporal and spatial scale on sediment budgets as well as on sedimentary and morphodynamic processes in open water environments.
Contributions may refer but are not restricted to:
• Measurements of suspended sediment and/or bedload transport in open water environments, e.g., with classical or novel methods;
• Determination of sediment characteristics, e.g., with mechanical bed material samplers or freeze core technique;
• Innovative measurement approach or techniques aimed for validation and calibration of numerical models;
• Measurements of critical bed shear stress of cohesive sediments, e.g., with benthic flumes or miscellaneous devices;
• Monitoring of morphological changes like lake and reservoir sedimentation, bank erosion or bed armoring, meandering
migration, river bends evolution;
• Measuring networks / multiple point datasets;
• Large- or small-scale monitoring concepts including case studies;
• In-situ or laboratory calibration of measurement data using classical or novel (e.g., machine learning) approaches;

Complex hydro-morphological processes, such as sediment erosion, transport, deposition, or fan development, affect open water environments, including rivers, estuaries as well as lakes and reservoirs. Consequently, many research tasks as well as practical applications rely on the correct prediction of these processes. During the last decades, numerical models have become a powerful tool in the research fields of hydraulic engineering and geosciences to simulate these hydro-morphological processes. With improved algorithms as well as an ever-growing computational power, it became feasible to simulate the interaction of water, sediments, and air with high resolution in space and time. In addition, with an increasing quantity and quality of validation data from laboratory experiments and field studies, numerical models are continuously enhanced so that many good examples of sediment transport modelling offer new insights in multiphase processes, e.g., dune development, river bed armouring or density-driven transport. Hence, new generations of numerical techniques open the possibility to explore numerous outstanding research questions related to hydro-morphologic processes. Artificial Intelligence procedures offer an additional alternative to hydro-morphological studies, e.g., determining particle size or floodplain vegetation cover.
The main goal of this session is to bring together scientists and engineers, who develop, improve, and apply numerical models of multiphase flows for sediment transport in open water environments. We invite contributions that deal with numerical modelling from small-scale, such as bed structure development, to large-scale interactions, such as long-term development of hydro-morphological processes in rivers, lakes, reservoirs, and estuaries.
Contributions may refer, but are not restricted, to:
• Entrainment processes of sediments (from cohesive sediments to armoured river beds)
• Bed load and suspended sediment transport processes (including flocculation processes)
• Simulation of sediment management including planning, operation and maintenance of hydro power plants
• Design and evaluation of restoration measures to revitalize rivers
• Navigation issues, such as sediment replenishment, dredging and erosion induced by ship generated waves
• Flood related issues of long term effects of morphological bed changes on flood security
• Eco-hydraulics such as flow – sediment – vegetation interaction
• Density driven transport

Ecohydrology, i.e., the study of the interactions between water and ecosystems, is expanding rapidly as a field of research, beyond traditional discipline boundaries in terms of questions and approaches. This session aims to draw examples from this wide field, portraying the current diversity and common features of research frontiers in ecohydrological studies, as well as the range of methods employed. We thus encourage contributions showing novel results or methods when tackling questions related to the coupling of ecological, biogeochemical and hydrological processes, at scales ranging from the single organ or organisms to whole ecosystem/catchment. Contributions relative to all terrestrial and aquatic systems are welcome, including those relative to managed ecosystems, showing how human intervention alters the interactions between water and ecosystems.

This session provides a platform for interdisciplinary science addressing the continuum from the river source to the sea. A systems approach is indispensable for science-based solutions to sustainably manage complex River-Sea social-ecological systems. Studies linking environmental and social sciences and crossing geographical borders are particularly invited: from the river source and its catchment through estuaries, deltas and marshlands across the freshwater-marine water transition into the coastal sea, including surface-groundwater interaction. Studies addressing the impacts of climate change and extreme events and the impact of human activities on water and sediment quality and quantity, hydromorphology, biodiversity, ecosystem functioning and services of River-Sea continua are of particular interest.
We need to understand how River-Sea Systems function and to address many open questions. How are River-Sea continua changing due to human pressures? What is the impact of processes in the catchment on coastal and marine systems function, and vice versa? How can we discern between human-induced changes or those driven by natural processes from climate-induced variability and extreme events? What will the tipping points of social-ecological system states be and what will they look like? How can we better characterise river-sea systems from the latest generation Earth observation to citizen science based observatories. How can we predict short and long-term changes in River-Sea-Systems to manage them sustainably? What is the limit to which it is possible to predict the natural and human-influenced evolution of River-Sea-Systems? The increasing demand to balance intensive human use and environmental protection in River-Sea Systems requires holistic and integrative research approaches with the ultimate goal of enhanced system understanding as the knowledge base for sustainable management solutions.

Evapotranspiration (ET) is the key water flux at the interface of soil, vegetation and atmosphere. Methods to quantify this flux (and its individual components) have been developed within different research disciplines encompassing plant physiology, soil science, meteorology, hydrology and more. However, each method refers to a specific measurement scale and contains its own uncertainties. Bridging these scales for comparisons between the different methods – as well as remote sensing products and model outputs – requires careful consideration of the associated uncertainties and scaling assumptions.
This session will mainly focus on the variety of ET estimates from different in-situ devices such as lysimeters, sap flow sensors, eddy covariance stations, scintillometers, approaches like the Bowen ratio method and others, including reporting and comparing the respective uncertainties of the methods. Additionally, we want to address the scale dependency of the various approaches and the scale gap between in-situ ET data, remote sensing products and catchment- or landscape-scale modelled ET. We welcome contributions that (1) assess and compare established and new in-situ ET measurements, (2) address uncertainty in the respective methods, (3) analyse trends as well as spatial and temporal patterns (including day- and nighttime processes) in in-situ measured ET data, (4) include cross-scale comparisons and scaling approaches and (5) incorporate in-situ measurements into modeling approaches.
Stable isotopes are powerful tools for tracing fluxes of water and associated nutrients in the soil-plant-atmosphere continuum. They are increasingly used by various disciplines to better understand the functioning of the soil-plant-atmosphere system. While new methods allow measurements at high spatial and temporal resolution, studies applying tracer methods are now tackling complex interactions between soil processes, plant physiology and ecology, and variable atmospheric drivers. As such, methodological developments and changes are happening quickly and have a strong bearing on process understanding and interpretation of findings. This session aims to address the current state of the art for methods, applications, and process interpretations using stable isotopes in the critical zone and to foster interdisciplinary exchange. We welcome experimental and modeling studies that present methodological developments and applications of isotope tracers to improve the actual knowledge of the water and nutrient exchanges at the soil-plant-atmosphere interfaces. Studies that seek to cross disciplinary boundaries and reveal new eco-hydrological process understanding are especially welcome.

Peatlands develop in specific hydrological settings and are thus sensitive to changes in climate and hydrological boundary conditions. The hydrology of peatlands is fundamental to their functions and development. Soil hydrological properties can change drastically after disturbances such as drainage, permafrost thaw, or mechanical compaction, causing challenges for both model parameterization and re-wetting measures. Pristine peatlands offer and regulate many ecosystem services such as biodiversity, carbon storage, and nutrient retention. Hydrology is a key control for a number of these services. Furthermore, the effects of peatlands (both pristine and disturbed) on flood retention, support of low flows and regional climate are much debated. As hydrological and biotic processes in peatlands are strongly coupled, estimating the eco-hydrological response of peatlands under climate change and linking it to vegetation development and greenhouse gas emissions is a demanding task for modelers. This session addresses peatlands in all latitudes, including especially permafrost and tropical peatlands for which field studies are scarce and the inclusion into Earth system models is largely pending.
This session focuses on:
(1) hydrological processes operating in all types of peatlands (pristine, disturbed, degraded, drained, managed, rehabilitated or re-wetted) in northern and tropical latitudes, and
(2) the first-order control of peatland hydrology on all kinds of peatland functions.
We aim to boost knowledge transfer across spatial/temporal scales and methods; from the pore to the global scale, including laboratory, field, remote sensing, and modeling studies on hydrological, hydrochemical, biogeochemical, ecohydrological or geophysical topics, as well as ecosystem service assessments.

Groundwater-surface water interfaces are integral components of aquifer-river and aquifer-lake continua. Groundwater-surface water interactions result in strong bidirectional interactions between surface waters, aquifers and connecting interfaces such as hyporheic zones, benthic zones, riparian corridors and lake sediments. Current research focuses on the effects of water exchange on the transport and transformation of nutrients, microplastics and pollutants. It also addresses the control of heat, oxygen and organic matter budgets available to microorganisms and macroinvertebrates in sediments. There is still a need to better understand the links between physical, biogeochemical, and ecological process dynamics at groundwater-surface water interfaces and their implications for fluvial ecology or limnology, respectively. It is important to consider the response of exchange fluxes to environmental and climate effects at different spatial and temporal scales (e.g. river channel, alluvial aquifer, regional groundwater flow). We see the biggest and most urgent challenges of this research in upscaling and downscaling of a general conceptual framework and an improved process understanding for groundwater-surface water interfaces. We also welcome contributions that address the development and application of novel experimental methods to study the physical, biogeochemical and ecological conditions at the groundwater-surface water interface in rivers, lakes, riparian zones and wetlands. We are also looking forward to investigating the role of hyporheic processes in the retention and natural attenuation of nutrients and pollutants, particularly with regard to their impact on surface and groundwater quality. In addition to experimental work, we are interested in hydrological, biogeochemical and ecological modelling approaches (e.g. transient storage models, coupled groundwater-surface water models, etc.). Finally, we welcome the presentation of research on the impact of groundwater-surface water interactions on management and risk assessment in view of the European Water Framework Directive.

Session dinner
We organise a session dinner for the gw-sw community every year. This time the dinner will take place the evening before our session: Tuesday 24.05.2022 at 7 pm. We have reserved tables: Summerstage, Rotenlöwengasse 19/14, 1090 Vienna, https://www.summerstage.at. We would be happy to meet you there. Unfortunately, the weather forecast is very bad with lots of rain and temperatures around 18 °C. The tables will be in a covered outdoor area. Considering Covid the choice of outdoor tables is probably better than a dinner inside the restaurant.
Held annually since 2005, the session has been enjoying continuously growing interest within the EGU programme HS10 “Ecohydrology, wetlands and estuaries” . The session is focused on research of lakes, enclosed or semi-enclosed seas (Baltic Sea, North Sea, Black Sea, Caspian Sea, Aral Sea, etc.), gulfs, and lagoons. The event is intended as interdisciplinary between hydrology, limnology and oceanography. Its scope encompasses physical, chemical, and biological aspects of lakes and inland seas, and offers a forum for both observational and modelling studies.
Session content:
As confined water bodies with limited exchanges, lakes and inland seas are particularly vulnerable to climatic and human impacts accumulated over broad catchment areas. Hence, they mirror both the global change effects and
anthropogenic pressures, perhaps, stronger than any other aquatic objects. Lakes and inland seas
also play an important role in ecosystem services such as fisheries, aquaculture, tourism, and others. These multifunctional roles require careful governance measures to avoid hydrological and environmental deterioration.
Research of lakes and inland seas admits many common approaches and techniques. Oceanographic methodology and instrumentation are often applicable to limnological studies. Reciprocally, insights obtained from lakes can also be instructive with respect to marine systems. This interdisciplinary session provides a joint forum for oceanographers, limnologists, and hydrologists interested in processes governing physical, chemical, and biological regimes of various lakes and inland seas of the world, as well as their responses to climate change and anthropogenic impacts.
The modern scientist has to operate in the Research-Services-Policy nexus to create real-world impact. The challenge is daunting and the opportunities are endless. What is truly the role of a scientist? What is your current position in this nexus? Where would you like to be in the future?
By sharing and discussing how our work is related to hydrological research, services and policy we can gain insight into how we, as a community, are positioned within this nexus. From there, we can identify opportunities and challenges associated with moving into new areas where we want to contribute, both personally and institutionally.
In this synergistic session, we will first use online interactive tools to explore where we, personally and as a group, fit within the Research-Services-Policy nexus. In the second part, we will have roundtable discussions on the visual outcomes of the first activity.
The objectives of this short course are to:
- create awareness of the several roles we can play as hydrologists,
connect over the challenges that come with balancing these different roles and sharing insights,
- identify topics / subjects / actors / issues and potential interlinks between hydrological research, services, and policy,
- and define a group perspective on the issues central in the proposed great debate “Hydrology and Earth System Science: research, services or policy?”
We embrace the “hybrid GA concept” by offering interactive activities using online platforms (survey, mind mapping and art tools) to promote engagement in the discussion regardless of participants’ locations and modes of attendance.
Anyone interested in the sciences, services and policy-making is encouraged to participate. A healthy mix and diversity of participants will greatly improve the experience for all involved.
This is a complementary event to the proposed Great Debate “Hydrology and Earth System Science: research, services or policy?”, and is organised in cooperation with the Young Hydrologic Society (http://younghs.com/).

On 9 August 2021, the Intergovernmental Panel on Climate Change (IPCC) released the first volume of its 6th Assessment Report (AR6). The Working Group I contribution to the Report (Climate Change 2021: The Physical Science Basis) synthesises over 14,000 publications and represents the most comprehensive and up-to-date assessment of the climate system and climate change. Crucially, the Report highlights the unprecedented and potentially irreversible influence of anthropogenic climate forcing, and for the first time, explicitly states that human influence on the climate system is unequivocal.
This short course will be a panel discussion where authors and contributors of Working Group I unpack how the IPCC 6th Assessment Report (AR6) is produced, provide personal behind-the-scenes insight on its development, and discuss its global impact, including how it is used to inform policy. Authors of the report will share their experiences of working on the report before and through the COVID pandemic. Panelists will also emphasise various ways in which scientists of all career stages can contribute to the IPCC process. Ample time will be allocated for open discussion for the audience to ask related questions to the panelists.
For more information about the AR6 please visit the IPCC website: https://www.ipcc.ch/.
One of the fundamental drivers of scientific progress is research integration and synthesis, which is essentially beneficial for developing research vision. Hence, literature reviews prove to be highly useful to many researchers at all academic stages. Analysing the literature and writing reviews for a thesis, article or project proposal can be sometimes challenging to fresh early career scientists. For a review paper even greater attention must be given to the methodological approach to conduct a reproducible and thorough review of the existing scientific literature.
In this short course participants will be given an overview of (literature) review types and learn about existing guidelines for conducting reviews. They will be introduced to available R packages for literature search and conducting systematic reviews. The course will also cover some insights from an editor’s perspective with helpful tips on how to write a review paper.
This session is organized in cooperation with the Young Hydrologic Society (http://younghs.com/).

R is an open-source, versatile programming language that is suitable for multi-scale analyses from just a few observations to big data and high-performance computing. It has a growing, enthusiastic user-base (including hydrologists) that is responsible for a continuous stream of ever more efficient and useful packages and workflows.
Running for its fifth year, this EGU short course, co-organised by the Young Hydrologic Society (younghs.com), will introduce and showcase a selection of both core and recently developed R packages that can be applied to data analyses in hydrology, as well as other scientific disciplines.
The course will be delivered by hydrologists with wide experience in subjects including: hydrological modelling (including flood and drought analysis), forecasting, statistics, and eco-hydrology.
Topics covered in this years’ course include:
• Topic tbd (Claudia Brauer)
• Identification of hydrologic events (Conrad Wasko + Danlu Guo)
• Flood forecast verification in R (Andrea Ficchi)
• The (mis)use of colours in scientific visualizations (Michael Stoelzle)
• Machine learning for spatio-temporal modelling (Razi Sheikholeslami)
This course contributes new topics to those delivered in previous years, building upon the openly accessible Github repository for hydrologists using R in their work (https://github.com/hydrosoc).

Detailed programme:
8.30-8.50 Identification of hydrologic events (Conrad Wasko + Danlu Guo)
8.50-9.10 Flood forecast verification in R (Andrea Ficchi)
9.10-9.30 Machine learning for spatio-temporal modelling (Razi Sheikholeslami)
9.30-9.50 The (mis)use of colours in scientific visualizations (Michael Stoelzle)
Visualisation of scientific data is an integral part of scientific understanding and communication. Scientists have to make decisions about the most effective way to communicate their results everyday. How do we best visualise the data to understand it ourselves? How do we best visualise our results to communicate with others? Common pitfalls can be overcrowding, overcomplicated plot types or inaccessible color schemes. Scientists may also get overwhelmed by the graphics requirements of different publishers, for presentations, posters etc. This short course is designed to help scientists improve their data visualization skills in a way that the research outputs would be more accessible within their own scientific community and reach a wider audience.
Topics discussed include:
- Choosing a plot type – keeping it simple
- Color schemes – which ones to use or not to use
- Creativity vs simplicity – finding the right balance
- Producing your figures – software and tools
- Figure files – publication ready resolutions
This course is organized by the Young Hydrologic Society (YHS), enabling networking and skill enhancement of early career researchers worldwide. Our goal is to help you make your figures more accessible by a wider audience, informative and beautiful. If you feel your graphs are complicated or not intuitive, we welcome you to join this short course.

We have developed an open source software package in python for ground-based GNSS reflections – gnssrefl (https://github.com/kristinemlarson/gnssrefl). This new software supports geoscientists wishing to measure in situ snow accumulation, permafrost melt, firn density, tides, and lake/river levels. We have developed videos (hosted on youtube) to help new users understand both the basic concepts of GNSS reflections and how to install and run the gnssrefl code. More than a dozen use cases are available online; Jupyter Notebooks have been developed as well. We envision the EGU tutorial session to be hands-on and interactive, with a focus on demonstrating the gnssrefl software and online tools (https://gnss-reflections.org), examining and discussing environmental results derived from GNSS data taken from public archives, and analyzing new datasets suggested by the students.
Public information:
We have developed an open source code in python (gnssrefl) that allows users to measure either water levels or snow accumulation using GNSS data. This session will be devoted to helping users understand how to run and install the code. Please see the github (https://github.com/kristinemlarson/gnssrefl) repository for some tips on how to install the gnssrefl package on your local machine. We currently support the python code on linux and macs, with docker images for these and PCs. We also have links to jupyter notebooks. There is a complementary web app at https://gnss-reflections.org.
Research, especially for early career scientists (ECS), starts with the spark of an idea and is then often challenged by empirical or methodological road bumps and seemingly dead ends. In Earth Science research, we face a diverse range of challenges, including (1) access difficulties, whether for field sites, equipment or data, (2) problems of temporal and spatial scaling and extrapolation and (3) a lack of methods, theory or knowledge or (4) every day live challenges as a scientist. As part of SC4 we want to address some of those 'problems'. In the discussion of these challenges we seek to find possible solutions, suggest new research approaches and methods, and encourage further networking amongst early career scientists at future international conferences.
We will start the session at this year's hybrid meeting with 2 minute ‘pop-up’ presentations outlining some challenges. These pop-ups are followed by chaired and structured outbreak group discussions. There will be the option to join these discussions both in-person and virtually. To wrap up the session, solutions and suggestions from each group are presented to the whole session in a final discussion. This short course lives by your input, so participants are expected to actively engage to crowd solve the presented challenges. To ensure that people are able to have a safe and open space to share their ideas, we ask you to join for the whole session. You can get an idea of past crowd-solving sessions, both in-person and online, from our 2019 (EGU blog) and 2021 (EGU blog) blog posts, see links below.
If you have a 'problem' you would like to discuss in the networking session with us, please send a short statement (3-4 sentences) of your idea or challenge and your motivation for solving it to us, by March 1st, 2022. We expect a non-hierarchic, respectful and constructive environment for the discussions, which will hopefully encourage the participants to identify and approach problems faced by early-career scientists.
What is the “Potsdam Gravity Potato”? What is a reference frame and why is it necessary to know in which reference frame GNSS velocities are provided? Geodetic data, like GNSS data or gravity data, are used in many geoscientific disciplines, such as hydrology, glaciology, geodynamics, oceanography and seismology. This course aims to give an introduction into geodetic datasets and presents what is necessary to consider when using such data. This 105-minute short course is part of the quartet of introductory 101 courses on Geodynamics 101, Geology 101 and Seismology 101.
The short course Geodesy 101 will introduce basic geodetic concepts within the areas of GNSS and gravity data analysis. In particular, we will talk about:
- GNSS data analysis
- Reference frames
- Gravity data analysis
We will also show short examples of data handling and processing using open-source software tools. Participants are not required to bring a laptop or have any previous knowledge of geodetic data analysis.
Our aim is to give you more background information on what geodetic data can tell us and what not. You won’t be a Geodesist by the end of the short course, but we hope that you are able to have gained more knowledge about the limitations as well as advantages of geodetic data. The course is run by early career scientists from the Geodesy division, and is aimed for all attendees (ECS and non-ECS) from all divisions who are using geodetic data frequently or are just interested to know what geodesists work on on a daily basis. We hope to have a lively discussion during the short course and we are also looking forward to feedback by non-geodesists on what they need to know when they use geodetic data.

Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

Through a wealth of geospatial data, growing computational power, and demonstrated success of application across many fields, artificial intelligence (in particular, machine learning) promises to advance our understanding of natural hazards and our ability to predict and respond to natural disasters. The ITU/WMO/UNEP Focus Group AI for Natural Disaster Management (FG-AI4NDM) is building a community of experts and stakeholders to identify best practices in the use of AI for data processing, improved modeling across spatiotemporal scales, and providing effective communication. This multidisciplinary FG-AI4NDM-session invites contributions addressing challenges related to floods, landslides, earthquakes, volcanic eruptions, tsunamis, among others, as well as multi-hazard. It also welcomes presentations on novel AI methods (including advances in automated annotation, explainability, etc.), which are hazard agnostic.
In a fast-changing environment, earth’s ecosystems are facing multiple stressors compromising the provision of essential services for mankind, and the resiliency of the natural environment itself.
Climate change, water pollution and scarcity affect biodiversity, socio-economic and climate related vulnerabilities and as a consequence, water and food security and human health.
The recent European Green Deal aims at Europe becoming the world’s first climate-neutral continent by 2050 and it does so by setting climate, energy, transport and taxation policies fit for reducing net greenhouse gas emissions by at least 55% by 2030. This program sets ambitious yet realistic targets for the next decades, auspicating the transformation of European Countries into a modern resource-efficient economy and society in line with the Sustainable Development Goals.
However, to address both the impacts as well as the causes of climate change, it is fundamental to create conditions where ecosystem services are optimized for both the local population and global objectives. Yet, the use of ecosystem services assessment in decision making might prove challenging when it comes to economic and social domains, as well as the perception and concept of natural environment may differ across disciplines. Such transdisciplinary approach plays a key role in Nature Based Solutions and opens up to the participation of multiple stakeholders in local governance, thus offering a multitude of co-benefits for the environment and for communities.
This session aims at opening a common ground between the natural, physical, social and economic sciences towards a resilient planet, by providing examples of challenges and opportunities and harmonizing best practices in this field.
We welcome transdisciplinary contributions on terrestrial, marine, and urban ecosystem services assessment that take into account the natural and the human dimension, advance in modelling complex spatio-temporal and social dynamics and transdisciplinary approaches towards nature inspired and supported solutions for social benefits and ecosystems’ resilience.

Land–atmosphere interactions often play a decisive role in shaping climate extremes. As climate change continues to exacerbate the occurrence of extreme events, a key challenge is to unravel how land states regulate the occurrence of droughts, heatwaves, intense precipitation and other extreme events. This session focuses on how natural and managed land surface conditions (e.g., soil moisture, soil temperature, vegetation state, surface albedo, snow or frozen soil) interact with other components of the climate system – via water, heat and carbon exchanges – and how these interactions affect the state and evolution of the atmospheric boundary layer. Moreover, emphasis is placed on the role of these interactions in alleviating or aggravating the occurrence and impacts of extreme events. We welcome studies using field measurements, remote sensing observations, theory and modelling to analyse this interplay under past, present and/or future climates and at scales ranging from local to global but with emphasis on larger scales.

An increasing number of single model large ensemble simulations from Global Climate Models (GCM), Earth System Models (ESM), or Regional Climate Models (RCM) have been generated over recent years, to investigate internal variability and forced changes of the climate system — and to aid the interpretation of the observational record by providing a range of historical climate trajectories that could have been. The increased availability of large ensembles also enables new and inter-disciplinary applications beyond large-scale climate dynamics.
This session invites studies using large GCM, ESM, or RCM ensembles looking at the following topics: 1) Reinterpretation of the observed record in light of internal variability; 2) forced changes in internal variability; 3) development of new approaches to attribute and study observed events or trends; 4) impacts of natural climate variability; 5) assessment of extreme and compound event occurrence; 6) combining single model large ensembles with CMIP archives for robust decision making; 7) large ensembles as testbeds for method development.
We welcome research across all components of the Earth system. Examples include topics ranging from climate dynamics, hydrology and biogeochemistry to research on the role of internal variability in impact studies, focused for example on agriculture, air pollution or energy generation and consumption. We particularly invite studies that apply novel methods or cross-disciplinary approaches to leverage the potential of large ensembles.

With recent extreme events reaching far beyond existing records, such as the Pacific Northwest heat wave and severe flooding in Western Europe, eastern US and across China, the discussion to what extent we are prepared for unprecedented extremes and whether existing methods and models are able to capture them has flared up. It is becoming increasingly essential to understand and quantify plausible rare, high-impact events for risk management and adaptation.
Methods to understand and evaluate low-likelihood extreme events have seen substantial advancements over the recent years. Event attribution studies are now providing rapid analyses of unprecedented extreme events; physical climate storylines are developed to evaluate plausible rather than likely events; causal inference is used to understand drivers of very rare events; near-miss events and potential analogues in space, historical and paleo archives are evaluated; spatial extreme value analysis and machine learning methods are applied, large ensembles representing various outcomes are generated, such as Single Model Initial-condition Large Ensembles (SMILEs); and weather prediction systems are increasingly being employed, such as the through the UNprecedented Simulated Extremes using ENsembles (UNSEEN) approach.
This session aims to bring together communities from weather prediction, climate projection, hydrology to impact and risk management, and to learn from the variety of methods to understand and quantify low-likelihood extreme events in the present and future climate. The session welcomes contributions at all temporal and spatial scales, and all types of extremes and invites novel methods – including downward counterfactuals and causal inference – as well as new results on unforeseen climate risks – including those from compound events and low-likelihood high-warming outcomes.

This interdisciplinary session brings together modellers and observationalists to present results and exchange knowledge and experience in the use of inverse methods, geostatistics and data assimilation - including machine learning - in cryospheric science.
In numerous research fields it is now possible not only to deduce static features of a physical system but also to retrieve information on transient processes between different states or even regime shifts. In the cryospheric sciences a large potential for future developments lies at the intersection of observations and models with the aim to yield prognostic capabilities in space and time. Compared to other geoscientific disciplines like meteorology or oceanography, where techniques such as data assimilation have been well established for decades, in cryospheric sciences only the foundation has been laid for the use of these techniques, one reason often being the sparsity of observations.
We invite contributions from a wide range of methodologies - from satellite observations to deep-looking geophysical methods and advancements in numerical techniques, and from topics including permafrost, sea ice and snow to glaciers and ice sheets, covering static system characterisations as well as transient processes.

The ecological stability, soil degradation, and hydrological extremes are the main driving elements and powerful tools associated with climate change on reducing or increasing the acceleration of climate change.
Climate change is a natural process, but the latest scientific research proves that it is significantly accelerated by human activity. Adequate steps can be taken by humans (for instance land use/land cover changes) in order to reduce the risks and consequences of the effects of climate change. Despite this knowledge, which is well known, progress is still slow, and the negative consequences prevail over the positive remedies.
The session should reflect, discuss, and share scientific knowledge on a local and regional scale with the aim to increase innovative knowledge thanks to multidisciplinary links at national, international, and global levels.
This session is open within a wide range of relevant scientific topics as follows:
• hydrological extremes as one of the main impacts of climate change;
• lack of precipitation or extreme precipitation - how to reduce and decrease these extremes by adequate measures;
• the connection between deteriorating ecological stability and climate change;
• new methods and procedures for reducing existing manifestations of climate change (such as soil degradation, carbon sequestration, changes in natural, agricultural, and forest ecosystems, reduction of overall ecological stability and character of the landscape);
• proposal of measures to prevent the occurrence of the above-mentioned impacts;
• the sustainability of management practices, the importance of appropriate land use management as the main tool for preventing degradation processes, floods, and droughts, improving the condition of forest ecosystems in order to increase the overall character of the landscape.

High-impact climate and weather events typically result from the interaction of multiple hazards across various spatial and temporal scales. These events, also known as Compound Events, often cause more severe socio-economic impacts than single-hazard events, rendering traditional univariate extreme event analyses and risk assessment techniques insufficient. It is therefore crucial to develop new methodologies that account for the possible interaction of multiple physical drivers when analysing high-impact events. Such an endeavour requires (i) a deeper understanding of the interplay of mechanisms causing Compound Events and (ii) an evaluation of the performance of climate/weather, statistical and impact models in representing Compound Events.
The European COST Action DAMOCLES coordinates these efforts by building a research network consisting of climate scientists, impact modellers, statisticians, and stakeholders. This session creates a platform for this network and acts as an introduction of the work related to DAMOCLES to the research community.
We invite papers studying all aspects of Compound Events, which might relate to (but are not limited to) the following topics:
Synthesis and Analysis: What are common features for different classes of Compound Events? Which climate variables need to be assessed jointly in order to address related impacts? How much is currently known about the dependence between these variables?
Stakeholders and science-user interface: Which events are most relevant for stakeholders? What are novel approaches to ensure continuous stakeholder engagement?
Impacts: What are the currently available sources of impact data? How can they be used to link observed impacts to climate and weather events?
Statistical approaches, model development and evaluation: What are possible novel statistical models that could be applied in the assessment of Compound Events?
Realistic model simulations of events: What are the physical mechanisms behind different types of Compound Events? What type of interactions result in the joint impact of the hazards that are involved in the event? How do these interactions influence risk assessment analyses?

Duration of the talks: 5 minutes + 2 minutes for questions and transition to the next speaker.

With global climate change affecting the frequency and severity of extreme meteorological and hydrological events, it is particularly necessary to develop models and methodologies for a better understanding and forecasting of present-day weather induced hazards. Future changes in the event characteristics as well as changes in vulnerability and exposure are among the further factors for determining risks for infrastructure and society, and for the development of suitable adaptation measures. This session considers extreme events that lead to disastrous hazards induced by severe weather and climate change. These can, e.g., be tropical or extratropical rain- and wind-storms, hail, tornadoes or lightning events, but also (toxic) floods, long-lasting periods of drought, periods of extremely high or of extremely low temperatures, etc. Papers are sought which contribute to the understanding of their occurrence (conditions and meteorological development), to assessment of their risk (economic losses, infrastructural damages, human fatalities, pollution), and their future changes, to the ability of models to reproduce them and methods to forecast them or produce early warnings, to proactive planning focusing on damage prevention and damage reduction. In order to understand fundamental processes, papers are also encouraged that look at complex extreme events produced by combinations or sequences of factors that are not extreme by themselves. The session serves as a forum for the interdisciplinary exchange of research approaches and results, involving meteorology, hydrology, environmental effects, hazard management and applications like insurance issues.
This session aims to share innovative approaches to developing multi-hazard risk assessments and their components (hazard, exposure, vulnerability and capacity), and to explore their applications to disaster risk reduction.
Effective disaster risk reduction practices and the planning of resilient communities requires the evaluation of multiple hazards and their interactions. This approach is endorsed by the UN Sendai Framework for Disaster Risk Reduction. Multi-hazard risk and multi-hazard impact assessments look at interaction mechanisms among different natural hazards, and how spatial and temporal overlap of hazards influences the exposure and vulnerability of elements at risk. Moreover, the uncertainty associated with multi-hazard risk scenarios needs to be considered, particularly in the context of climate change and slow-onset hazards, such as Covid-19 and pandemics in general, characterized by dynamic changes in exposure and vulnerability that are challenging to quantify.
This session, therefore, aims to profile a diverse range of multi-hazard risk and impact approaches, including hazard interactions, multi-vulnerability studies, and multi-hazard exposure characterization. In covering the whole risk assessment chain, we propose that it will be easier to identify potential research gaps, synergies and opportunities for future collaborations.
We encourage abstracts which present innovative research, case study examples and commentary throughout the whole disaster risk cycle on (i) multi-hazard risk methodologies which address multi-vulnerability and multi-impact aspects; (ii) methodologies and tools for multi-hazard risk management and inclusive risk-informed decision making and planning; (iii) methodologies and tools for multi-hazard disaster scenario definition and management for (near) real-time applications; (iv) cross-sectoral approaches to multi-hazard risk, incorporating the physical, social, economic, and/or environmental dimensions; (v) uncertainty in multi-hazard risk and multi-hazard impact assessment; (vi) evaluation of multi-hazard risk under future climate and slow-onset hazards, including pandemics; (vii) implementation of disaster risk reduction measures within a multi-hazard perspective.

The purpose of this session is to: (1) showcase the current state-of-the-art in global and continental scale natural hazard risk science, assessment, and application; (2) foster broader exchange of knowledge, datasets, methods, models, and good practice between scientists and practitioners working on different natural hazards and across disciplines globally; and (3) collaboratively identify future research avenues.
Reducing natural hazard risk is high on the global political agenda. For example, it is at the heart of the Sendai Framework for Disaster Risk Reduction and the Paris Agreement. In response, the last decade has seen an explosion in the number of scientific datasets, methods, and models for assessing risk at the global and continental scale. More and more, these datasets, methods and models are being applied together with stakeholders in the decision decision-making process.
We invite contributions related to all aspects of natural hazard risk assessment at the continental to global scale, including contributions focusing on single hazards, multiple hazards, or a combination or cascade of hazards. We also encourage contributions examining the use of scientific methods in practice, and the appropriate use of continental to global risk assessment data in efforts to reduce risks. Furthermore, we encourage contributions focusing on globally applicable methods, such as novel methods for using globally available datasets and models to force more local models or inform more local risk assessment.

Hydrometeorological and geomorphological hazards account for 45% of the fatalities and 79% of global economic losses. Exacerbated by high seismic activity and rugged terrain, the Himalayan landscape is particularly susceptible to generating these events, which often transform into cascading hazards—an initial event causes a downstream hazard chain, e.g. glacial lake outburst floods to debris flows. These hazards interfere with increasing population pressure and expansion of settlements along rivers and new infrastructure developments such as roads and hydropower projects. Rising temperatures and changes in weather patterns in the wake of global warming likely elevate risks from hazards such as landslides, glacial lake outburst floods, riverine and flash floods. The complexity of these hazards and their underlying processes demand scientific efforts and approaches from multiple disciplines.
Multidisciplinary approaches and methodologies are important to holistically estimate and predict hazard events and interactions of multiple hazards, and to understand how vulnerable societies cope and respond to these hazards in the Himalayan region.
This session aims to bring together expertise on approaches, methods, and data to advance the understanding of the impacts and changes in the extremely high mountain landscapes, with a particular focus on the trends of hydro-geomorphological disasters on the Himalayas and their societal impacts.
We welcome contributions from research topics (but not restricted to):
-hydro-geophysical modeling (landslides, glacial lake outburst floods, riverine and flash floods)
-extreme event modeling
-remote-sensing-based observations
-risk/vulnerability assessment
-theories and models of reducing vulnerabilities and adaptation to natural hazards
-innovative data approaches to integrate natural and social science perspective
-recovery to natural hazards, in particular, usage of longitudinal data methods
The session is closely linked to the NHESS special issue “Estimating and Predicting Natural Hazards and Vulnerabilities in the Himalayan Region”. We encourage all session contributors to support this issue.

Increasing effects of climate change, urbanization, and increased interconnectedness between ecological, physical, human, and technological systems pose major challenges to disaster risk management in a globalised world. Economic losses from natural hazards and climate change are still increasing, and the recent series of catastrophic events across the world together with the COVID-19 crisis has manifested the urgent need to shift from single-hazard-based approaches to new and innovative ways of assessing and managing risk based on a multi-hazard and systemic risk lens. This calls for novel scientific approaches and new types of data collections to integrate the study of multiple natural processes and human influences triggering hazards, including studies of ecological, physical, socioeconomic, political, and technical factors that shape exposure and vulnerability of humans, sectors and systems across borders and scales.
Tackling the above challenges, this session aims to gather the latest research, empirical studies, and observation data that are useful for understanding and assessing the interplay between multiple natural hazards and social vulnerability to: (i) identify persistent gaps, (ii) propose potential ways forward, and (iii) inform resilience building strategies in the context of global change.

Climate-induced geohazards are known to increase with climate change causing more intense rainfall and more frequent extreme weather events. Use of vegetation on potentially unstable slopes and along stream banks is an example of Nature-Based Solutions (NBS) that can mitigate climate induced geohazards due their role at the soil-atmosphere interface. Vegetating slopes or stream banks are also key for ecological restoration and rewilding, providing several additional co-benefits. However, researchers in different fields of science or practitioners do not easily communicate, even though they are addressing aspects of the same problem.
Interdisciplinary research and bilateral communication are needed to document the effects of vegetation in hazard-prone areas in a measurable and applicable manner. These NBS must have an ecological approach, where in the long-term perspective, a multiple approach for biodiversity and ecosystem services will give mutual synergies.
This session aims to stimulate interdisciplinary communication, knowledge exchange and dissemination on plant-soil-atmosphere interaction, with focus on vegetation mitigating climate-induced geohazards, particularly shallow landslides and erosion.
Contributions documenting how vegetation and roots can be beneficial also in land use planning, restoration ecology, climate change adaptation are welcome within the fields of geotechnical engineering, plant ecology, biodiversity, alpine timberline, hydrogeology and agronomy.
Interaction between research and industry, with involvement of NBS entrepreneurs, are particularly welcome.
Topics of interested are listed, including, but not limited to:
• Experimental, either laboratory or field, or numerical investigation of plant-soil-atmosphere interaction and its relation to slope or bank stability
• How to implement morpho-mechanical parameters of plants in engineering design?
• Measuring and quantifying the effects of vegetation as NBS to mitigate climate-induced geohazards
• Tools, approaches, and frameworks demonstrating how vegetation can be used to mitigate climate-induced geohazards, while providing additional co-benefits
• Investigation on upscaling potential from laboratory to slope and catchment scale
• Case studies of restoration or stabilisation works, especially on design principles and performance assessment
• Ensuring interdisciplinary interaction and mutual synergies for studies containing vegetation as NBS among different disciplines

Debris flows are among the most dangerous natural hazards that threaten people and infrastructures in both mountainous and volcanic areas. The study of the initiation and dynamics of debris flows, along with the characterization of the associated erosion/deposition processes, is of paramount importance for hazard assessment, land-use planning and design of mitigation measures, including early warning systems. In addition, the impacts of climate change on debris-flow activity must be considered and carefully analysed, as the number of mountain areas prone to these events may increase in future.
A growing number of scientists with diverse backgrounds are studying debris flows and lahars. The difficulties in measuring parameters related to their initiation and propagation have progressively prompted research into a wide variety of laboratory experiments and monitoring studies. However, there is a need of improving the quality of instrumental observations that would provide knowledge for more accurate hazards maps and modeling. Nowadays, the combination of distributed sensor networks and remote sensing techniques represents a unique opportunity to gather direct observations of debris flows to better constrain their physical properties.
Scientists working in the field of debris flows are invited to present their recent advancements. In addition, contributions from practitioners and decision makers are also welcome. Topics of the session include: field studies and documentation, mechanics of debris-flow initiation and propagation, laboratory experiments, modeling, monitoring, impacts of climate change on debris-flow activity, hazard and risk assessment and mapping, early warning, and alarm systems.
Worldwide, the frequency and magnitude of extreme floods are steadily increasing, causing large scale flooding, accompanied by great economic/human losses, in inundation-prone areas of the world. It hampers well-being and economic growth in many countries, so that flood forecasting and flood risk assessment & management have become of upmost importance. New and rapidly developing techniques are becoming widespread, such as UAV (unmanned aerial vehicle), ML(Machine Learning) or satellite-based systems (e.g., SAR, Altimeter, SCATSAT-1, etc.). Combined with fit-for-purpose hydrodynamic/hydrological models, these techniques pave the way for breakthroughs in flood assessment and flood risk management. This provides a unique platform for the scientific community to explore the driving mechanisms of flood risk and to build up efficient strategies for flood mitigation and enhancing flood resilience. Emerging advances in computing technologies, coupled with big-data mining, have boosted data-driven applications, among which ML technology bearing flexibility and scalability in pattern extraction has modernised not only scientific thinking but also predictive applications.
This session invites presentations on research based on high-resolution aerial, satellite and ML techniques for flood monitoring and modelling, including mapping of inundation extent, flow depths, velocity fields, flood-induced morphodynamics, and debris transport. It also invites the presentation of innovative modelling techniques of flood hydrodynamics, flood hazard, damage and risk assessment, as well as flood relief prioritization, dam and dike (levees) break floods, and flood mitigation strategies. Studies dealing with the modelling uncertainties and modern techniques for model calibration and validation are particularly welcome. Furthermore, real-time flood inundation mapping is a critical aspect for the evacuation of people from low-lying areas and to reduce casualties. Acquisition of real-time data gained through UAV-based flood inundation mapping, ML and modelling techniques, as well as assessment of uncertainties in real-time aerial surveying are welcome in this session.

Geophysical and in-situ measurements offer important baseline datasets, as well as validation for modelling and remote sensing products. They are used to advance our understanding of firn, ice-sheet and glacier dynamics, sea ice processes, changes in snow cover and snow properties, snow/ice-atmosphere-ocean interactions, permafrost degradation, geomorphic mechanisms and changes in englacial and subglacial condition.
In this session we welcome contributions related to a wide spectrum of methods, including, but not limited to, advances in radioglaciology, active and passive seismology, geoelectrics, acoustic sounding, fiber-optic sensing, GNSS reflectometry, signal attenuation and time delay techniques, cosmic ray neutron sensing, ROV and drone applications, and electromagnetic methods. Contributions could be related to field applications, new approaches in geophysical or in-situ survey techniques, or theoretical advances in data analysis processing or inversion. Case studies from all parts of the cryosphere such as snow and firn, alpine glaciers, ice sheets, glacial and periglacial environments, permafrost, or sea ice, are highly welcome.
The focus of the session is to compare experiences in the application, processing, analysis and interpretation of different geophysical and in-situ techniques in these highly complex environments. We have been running this session for nearly a decade and it always produces lively and informative discussion. This session is offered as a fully hybrid vPICO: an engaging presentation format in which all authors will present their research orally as a quick-fire 2-minute overview, and then further present and discuss their research.

Soils largely contribute to sustain agro-systems production and provide many ecosystem services that are essential for addressing sustainable land and water management. Management of both soil and water resources is a primary socio-economic concern that requires a detailed description of the physical and biological process that occur into the soil-plant-atmosphere continuum system. Nevertheless, measuring soil state variables and hydraulic parameters is often difficult due to the many complex nonlinear physical, chemical and biological interactions that simultaneously control the transfer of heat and mass.
Infiltration experiments have been proposed as a simple mean to estimate soil hydraulic properties but their effectiveness is hampered by the effects of spatio-temporal variability across scales. High-resolution measurements of soil state variables, both over space and time, are thus crucial to describe and analyze soil hydraulic properties adequately.
The session focuses on the principles, capabilities, and applications of different techniques for monitoring state variables of soil and estimating soil hydraulic properties from infiltration experiments. Specific topics include, but are not limited to:
- Multiple measurement techniques and modelling approaches for determining state variables of soil;
- Innovative soil-water measurements techniques for linking the interactions of soil with plant and atmosphere compartments;
- Field infiltration techniques from a wide variety of devices in combination with dielectric and geophysical methods (i.e., TDR, FDR, GPR, ERT, etc.);
- New or revisited numerical and analytical models to account for physical, chemical and biological interaction in the soil-water flow models (multiple-porosity, permeability, hydrophobicity, clogging, shrinking-swelling, or biofilm development);
- Use of pedotransfer functions based on limited available in-situ measurements to estimate parameters that describe soil hydro-physical and thermal characteristics;
- Multi-data source methodologies also in combination with modelling for assessing the soil physics dynamics at different temporal and spatial scales.
We welcome contributions from simulated and real data investigations in the laboratory or field-based experiments, successful and failed case studies, and the presentation of new and promising modeling approaches, scenarios, and techniques.
A well-designed experiment is a crucial methodology in Soil Science, Geomorphology and Hydrology.
Depending on the specific research topic, a great variety of tempo-spatial scales is addressed.
From raindrop impact and single particle detachment to the shaping of landscapes: experiments are designed and conducted to illustrate problems, clarify research questions, develop and test hypotheses, generate data and deepen process understanding.
Every step involved in design, construction, conduction, processing and interpretation of experiments and experimental data might be a challenge on itself, and discussions within the community can be a substantial and fruitful component for both, researchers and teachers.
This PICO session offers a forum for experimentalists, teachers, students and enthusiasts.
We invite you to present your work, your questions, your results and your method, to meet, to discuss, to exchange ideas and to consider old and new approaches.

Our ability to understand biogeochemical cycles of carbon, nitrogen and phosphorus in aquatic ecosystems has evolved enormously thanks to advancements in in situ and laboratory measurement techniques. We are now able to provide a detailed characterisation of aquatic organic matter with spectroscopic and chromatographic methods and collect data on nitrogen and phosphorus concentrations in relation to highly dynamic hydrological events thanks to automated in situ instruments. Therefore, the aim of this session is to demonstrate how this methodological advancement improves our understanding of coupled hydrological, biogeochemical and ecological processes in aquatic environments controlling the fate of organic matter, nutrients and other chemicals.
Specifically, our ability to characterise different fractions of natural organic matter and organic carbon has increased thanks to a range of analytical methods e.g. fluorescence and absorbance spectroscopy, mass spectrometry and chromatography combined with advanced data mining tools. Matching the water quality measurement interval with the timescales of hydrological responses (from minutes to hours) thanks to automated in situ wet-chemistry analysers, optical sensors and lab-on-a-chip instruments has led to discovery of new hydrochemical and biogeochemical patterns in aquatic environments e.g. concentration-discharge hysteresis and diurnal cycles. We need to understand further how hydrochemical and ecological processes control those patterns, how different biogeochemical cycles are linked in aquatic environments and how human activities disturb those biogeochemical cycles by emitting excess amounts of nutrients to aquatic systems. In particular, there is a growing need to better characterise the origins, delivery pathways, transformations and environmental fate of organic matter and nutrients in aquatic environments along with identification of robust numerical tools for advanced data processing and modelling.

The United Nations has designated the 2020s as the decade of ecosystem restoration; and restoration of streams, rivers and their catchments is particularly important to restore ecosystems and halt biodiversity loss, in addition to achieving several sustainable development goals. Within Europe, river restoration is used to meet the EU Water Framework Directive objectives, and EU LIFE projects provide millions of euro per year to physical restoration. Furthermore, restoration of rivers and their catchments will prove both more important in the coming decades in order to mitigate and adapt to the effects of climate change and more challenging when restoring a moving target with altered flow, sediment, and ice regimes and habitat conditions. Restoration and management of rivers and their catchments will require a holistic view of multiple facets of river systems and will need to be process-based, including geomorphic, hydrological and ecological processes, incorporating an understanding of how these evolve and interact following restoration interventions. In addition, large wood (LW) is a key component of fluvial ecosystems and affects both flow and sediment transport processes. LW jams (i.e., logjams) can be used as a tool for river restoration increasing flow and bed heterogeneity. However, the transportation of LW may significantly increase during floods and LW jams can form at river infrastructure, creating an additional flood risk, which needs to be accounted for in management strategies of rivers. An interdisciplinary effort is required to improve our understanding of the complex interactions of wood with flow and sediment in fluvial ecosystems.
In this session we wish to highlight a broad range of research on methods, success/failure, and follow-up of river and catchment restoration and management. We are particularly interested in studies related to restoration with a changing baseline of climate conditions as well as aspects associated with LW; however, there are also many basic questions on how to manage and restore rivers that also need to be addressed, including time-to-recovery, resilience, relationships between different river facets, the impact of different spatial scales of restoration, etc. We hope this session will spark discussion among an interdisciplinary group of researchers of how to take into account a changing climatic baseline in future river restoration and evaluation of restoration success.
It becomes increasingly accepted that many regions all over the world are experiencing an increase in the frequency of extreme rainfall events and potentially in their properties. For predicting the impact of future climate change on the landscape, it is therefore vital to understand the dynamics of surface processes under extreme events. Furthermore, focusing on the conditions necessary for extreme events to occur can provide key insights into past changes in climate at different time scales. Extreme storms cause a multitude of hydrogeomorphic and natural hazards responses, including floods and respective fluvial responses, hillslope erosion and failures, and debris flows from slopes into fluvial systems. Measuring, evaluating, and predicting the impacts of extreme rainstorms, however, remains challenging due to the difficult-to-predict and complex nature of storms and rainfall-surface interactions.
This interdisciplinary session focuses on the causative chain which links the deterministic and mostly stochastic nature of the synoptic to meso/regional and watershed scales of extreme storms, to their respective transformation into watershed, slope, and stream hydrology, and to their geomorphic impact. We welcome studies from all the parts of this chain, from all climates, and at all temporal scales, that are focusing on the hydrological responses to extreme events and on their imprints on the landscape through erosion and sediment movement. We favor studies with emphasis on the final noticeable impact of extreme events on the landscape and/or on the integrated long-term consequences of extreme storm regime on landscape evolution. Especially, we encourage studies presenting new physical/stochastic modeling approaches that explicitly investigated the impact of extreme events on the landscape.

Recent advances in image collection, e.g. using unoccupied aerial vehicles (UAVs), and topographic measurements, e.g. using terrestrial or airborne LiDAR, are providing an unprecedented insight into landscape and process characterization in geosciences. In parallel, historical data including terrestrial, aerial, and satellite photos as well as historical digital elevation models (DEMs), can extend high-resolution time series and offer exciting potential to distinguish anthropogenic from natural causes of environmental change and to reconstruct the long-term evolution of the surface from local to regional scale.
For both historic and contemporary scenarios, the rise of techniques with ‘structure from motion’ (SfM) processing has democratized data processing and offers a new measurement paradigm to geoscientists. Photogrammetric and remote sensing data are now available on spatial scales from millimetres to kilometres and over durations of single events to lasting time series (e.g. from sub-second to decadal-duration time-lapse), allowing the evaluation of event magnitude and frequency interrelationships.
The session welcomes contributions from a broad range of geoscience disciplines such as geomorphology, cryosphere, volcanology, hydrology, bio-geosciences, and geology, addressing methodological and applied studies. Our goal is to create a diversified and interdisciplinary session to explore the potential, limitations, and challenges of topographic and orthoimage datasets for the reconstruction and interpretation of past and present 2D and 3D changes in different environments and processes. We further encourage contributions describing workflows that optimize data acquisition and processing to guarantee acceptable accuracies and to automate data application (e.g. geomorphic feature detection and tracking), and field-based experimental studies using novel multi-instrument and multi-scale methodologies. This session invites contributions on the state of the art and the latest developments in i) modern photogrammetric and topographic measurements, ii) remote sensing techniques as well as applications, iii) time-series processing and analysis, and iv) modelling and data processing tools, for instance, using machine learning approaches.
Denudational hillslope and fluvial processes, associated source-to-sink fluxes and sedimentary budgets are controlled by a range of environmental drivers and anthropogenic activities, exacerbated by the consequences of climate change. A better understanding of the drivers, mechanisms and rates of contemporary denudational hillslope and fluvial processes as well as of the sediment and hydrological connectivity across a range of different spatio-temporal scales and climatic zones has significant societal implications for water quality, hydraulic infrastructures, aquatic ecosystems, public safety, and biogeochemical cycles.
The session aims to bring together interdisciplinary researchers working across field, experimental, numerical modelling, remote sensing, and dating approaches who are advancing methods and providing new insights into: (i) slope mass movements (e.g., landslides, rockfalls, and debris flows) and related hazard cascades in mountainous environments; (ii) water, sediment and solute source-to-sink processes in different climate zones (e.g., cold climate, temperate, arid and tropical regions) from small headwaters to large river systems at event, seasonal, and multi-decadal scales; and (iii) the anthropogenic impacts and societal implications of changing hillslope and fluvial processes and possible solutions for future sustainable management.
We encourage the participation of early-career researchers and PhD students working in the fields of geomorphology, hydrology, hazard, glaciers, permafrost, and aquatic ecosystems, as we aim to expand and integrate the network of researchers addressing this complex subject across scientific disciplines.
This session is organized by the International Association of Geomorphologists (IAG) Working Group on Denudation and Environmental Changes in Different Morphoclimatic Zones (DENUCHANGE).

Statistical post-processing techniques for weather, climate, and hydrological forecasts are powerful approaches to compensate for effects of errors in model structure or initial conditions, and to calibrate inaccurately dispersed ensembles. These techniques are now an integral part of many forecasting suites and are used in many end-user applications such as wind energy production or flood warning systems. Many of these techniques are flourishing in the statistical, meteorological, climatological, hydrological, and engineering communities. The methods range in complexity from simple bias correction up to very sophisticated distribution-adjusting techniques that take into account correlations among the prognostic variables.
At the same time, a lot of efforts are put in combining multiple forecasting sources in order to get reliable and seamless forecasts on time ranges from minutes to weeks. Such blending techniques are currently developed in many meteorological centers.
In this session, we invite presentations dealing with both theoretical developments in statistical post-processing and evaluation of their performances in different practical applications oriented toward environmental predictions, and new developments dealing with the problem of combining or blending different types of forecasts in order to improve reliability from very short to long time scales.

The 2021-2022 Hunga Tonga-Hunga Ha'apai eruption in Tonga was among the largest of recent decades. The event was notable for its high intensity, generating a convective column that rapidly ascended well into the stratosphere; for the atmospheric pressure wave generated by the explosion, which was detected globally; and for generating a tsunami that was observable across Pacific Ocean shorelines. Following a series of preceding seismic and explosive events since December 2021, the sustained phase of the eruption on 15th January was relatively short lived, but the associated pressure wave and tsunami impacts were the most far-reaching since the eruption of Krakatau volcano in 1883. Tsunamis were recorded both locally and in the far-field, but their mechanism(s) remains uncertain; in the near field being from either (or both of) the collapsing eruption column or a phreatomagmatic explosion as the erupting mass mixed with sea water. In the far-field the tsunamis are possibly best explained by the massive atmospheric pressure wave, that is the first instrumentally recorded eruption-generated event of its type, which affected the entire global atmosphere and ionosphere, causing the observed infrasound waves and unusual long-period seismic resonances.
This interdisciplinary late-breaking session welcomes contributions from all disciplines involved in local and global observations of this eruption and its effects, including remote sensing observations and modeling as well as hazard assessment and estimation of damage and long-term consequences.
Heat extremes are already one of the deadliest meteorological events and they are projected to increase in intensity and frequency due to rising CO2 emissions. The hazard these events pose to society may therefore increase dramatically, and society will need to adapt if the worst impacts are to be avoided. This session therefore welcomes a broad range of new research addressing the challenge of extreme heat. Suitable contributions may: (i) assess the drivers and underlying processes of extreme heat in observations and/or models; (ii) explore the diverse socio-economic impacts of extreme heat events (for example, on aspects relating to human health or economic productivity); (iii) address forecasting of extreme heat at seasonal to sub-seasonal time scales; (iv) focus on societal adaptation to extreme heat, including the implementation of Heat-Health Early Warning Systems for disaster risk reduction.

Worldwide, the frequency and magnitude of extreme floods are steadily increasing, causing large scale flooding, accompanied by great economic/human losses, in inundation-prone areas of the world. It hampers well-being and economic growth in many countries, so that flood forecasting and flood risk assessment & management have become of upmost importance. New and rapidly developing techniques are becoming widespread, such as UAV (unmanned aerial vehicle), ML(Machine Learning) or satellite-based systems (e.g., SAR, Altimeter, SCATSAT-1, etc.). Combined with fit-for-purpose hydrodynamic/hydrological models, these techniques pave the way for breakthroughs in flood assessment and flood risk management. This provides a unique platform for the scientific community to explore the driving mechanisms of flood risk and to build up efficient strategies for flood mitigation and enhancing flood resilience. Emerging advances in computing technologies, coupled with big-data mining, have boosted data-driven applications, among which ML technology bearing flexibility and scalability in pattern extraction has modernised not only scientific thinking but also predictive applications.
This session invites presentations on research based on high-resolution aerial, satellite and ML techniques for flood monitoring and modelling, including mapping of inundation extent, flow depths, velocity fields, flood-induced morphodynamics, and debris transport. It also invites the presentation of innovative modelling techniques of flood hydrodynamics, flood hazard, damage and risk assessment, as well as flood relief prioritization, dam and dike (levees) break floods, and flood mitigation strategies. Studies dealing with the modelling uncertainties and modern techniques for model calibration and validation are particularly welcome. Furthermore, real-time flood inundation mapping is a critical aspect for the evacuation of people from low-lying areas and to reduce casualties. Acquisition of real-time data gained through UAV-based flood inundation mapping, ML and modelling techniques, as well as assessment of uncertainties in real-time aerial surveying are welcome in this session.

With global climate change affecting the frequency and severity of extreme meteorological and hydrological events, it is particularly necessary to develop models and methodologies for a better understanding and forecasting of present-day weather induced hazards. Future changes in the event characteristics as well as changes in vulnerability and exposure are among the further factors for determining risks for infrastructure and society, and for the development of suitable adaptation measures. This session considers extreme events that lead to disastrous hazards induced by severe weather and climate change. These can, e.g., be tropical or extratropical rain- and wind-storms, hail, tornadoes or lightning events, but also (toxic) floods, long-lasting periods of drought, periods of extremely high or of extremely low temperatures, etc. Papers are sought which contribute to the understanding of their occurrence (conditions and meteorological development), to assessment of their risk (economic losses, infrastructural damages, human fatalities, pollution), and their future changes, to the ability of models to reproduce them and methods to forecast them or produce early warnings, to proactive planning focusing on damage prevention and damage reduction. In order to understand fundamental processes, papers are also encouraged that look at complex extreme events produced by combinations or sequences of factors that are not extreme by themselves. The session serves as a forum for the interdisciplinary exchange of research approaches and results, involving meteorology, hydrology, environmental effects, hazard management and applications like insurance issues.
Lightning is the energetic manifestation of electrical breakdown in the atmosphere, occurring as a result of charge separation processes operating on micro and macro-scales, leading to strong electric fields within thunderstorms. Lightning is associated with tropical storms and severe weather, torrential rains and flash floods. It has significant effects on various atmospheric layers and drives the fair-weather electric field. It is a strong indicator of convective processes on regional and global scales, potentially associated with climate change. Thunderstorms and lightning are also associated with the production of energetic radiation up to tens of MeV on time scales from sub-millisecond (Terrestrial Gamma-ray Flashes) to tens of seconds (gamma-ray glows).
This session seeks contributions from research in atmospheric electricity with emphasis on:
Atmospheric electricity in fair weather and the global electrical circuit
Effects of dust and volcanic ash on atmospheric electricity
Thunderstorm dynamics and microphysics
Middle atmospheric Transient Luminous Events
Energetic radiation from thunderstorms and lightning
Experimental investigations of lightning discharge physics processes
Remote sensing of lightning and related phenomena by space-based sensors
Thunderstorms, flash floods, tropical storms and severe weather
Modeling of thunderstorms and lightning
Now-casting and forecasting of thunderstorms using machine learning and AI
Regional and global lightning detection networks
Lightning Safety and its Societal Effects

Climate-induced geohazards are known to increase with climate change causing more intense rainfall and more frequent extreme weather events. Use of vegetation on potentially unstable slopes and along stream banks is an example of Nature-Based Solutions (NBS) that can mitigate climate induced geohazards due their role at the soil-atmosphere interface. Vegetating slopes or stream banks are also key for ecological restoration and rewilding, providing several additional co-benefits. However, researchers in different fields of science or practitioners do not easily communicate, even though they are addressing aspects of the same problem.
Interdisciplinary research and bilateral communication are needed to document the effects of vegetation in hazard-prone areas in a measurable and applicable manner. These NBS must have an ecological approach, where in the long-term perspective, a multiple approach for biodiversity and ecosystem services will give mutual synergies.
This session aims to stimulate interdisciplinary communication, knowledge exchange and dissemination on plant-soil-atmosphere interaction, with focus on vegetation mitigating climate-induced geohazards, particularly shallow landslides and erosion.
Contributions documenting how vegetation and roots can be beneficial also in land use planning, restoration ecology, climate change adaptation are welcome within the fields of geotechnical engineering, plant ecology, biodiversity, alpine timberline, hydrogeology and agronomy.
Interaction between research and industry, with involvement of NBS entrepreneurs, are particularly welcome.
Topics of interested are listed, including, but not limited to:
• Experimental, either laboratory or field, or numerical investigation of plant-soil-atmosphere interaction and its relation to slope or bank stability
• How to implement morpho-mechanical parameters of plants in engineering design?
• Measuring and quantifying the effects of vegetation as NBS to mitigate climate-induced geohazards
• Tools, approaches, and frameworks demonstrating how vegetation can be used to mitigate climate-induced geohazards, while providing additional co-benefits
• Investigation on upscaling potential from laboratory to slope and catchment scale
• Case studies of restoration or stabilisation works, especially on design principles and performance assessment
• Ensuring interdisciplinary interaction and mutual synergies for studies containing vegetation as NBS among different disciplines

In many parts of the world, weather represents one of the major uncertainties affecting performance and management of agricultural systems. Due to global climate changes the climatic variability and the occurrence of extreme weather events is likely to increase leading to substantial increase in agricultural risk and destabilisation of farm incomes. This issue is not only important for farm managers but also for policy makers, since income stabilisation in agriculture is frequently considered as a governmental task.
The aim of this session is to discuss the state of the art research in the area of analysis and management of weather-related risks in agriculture. Both structural and non-structural measures can be used to reduce the impact of climate variability including extreme weather on crop production. While the structural measures include strategies such as irrigation, water harvesting, windbreaks etc., the non-structural measures include the use of the medium-range weather forecast and crop insurance.
The topic is at the borderline of different disciplines, in particular agricultural and financial economics, meteorology, modelling and agronomy. Thus, the session offers a platform to exchange ideas and views on weather-related risks across these disciplines with the focus on quantifying the impact of extreme weather on agricultural production including impacts of climate change, analysis of financial instruments that allow reducing or sharing weather-related risks, evaluation of risk management strategies on the farm level, development of the theory of risk management and to exchange practical experiences with the different types of weather insurance.
This session has been promoted by:
• Natural hazard Early career scientists Team (NhET, https://blogs.egu.eu/divisions/nh/tag/early-career-scientists/)
• Research Center for the Management of Agriculutral and Environmental Risks (CEIGRAM, http://www.ceigram.upm.es/ingles/)
Flash floods triggered by heavy precipitation in small- to medium-sized catchments often cause catastrophic damages, which are largely explained by the very short response times and high specific peak discharge. Often, they are also associated with geomorphic processes such as erosion, sediment transport, debris flows and shallow landslides. The anticipation of such events is crucial for efficient crisis management. However, their predictability is still affected by large uncertainties, due to the fast evolution of triggering rainfall events, the lack of appropriate observations, the high variability and non-linearity in the physical processes, the high variability of societal exposure, and the complexity of societal vulnerability.
This session aims to illustrate current advances in monitoring, modeling, and short-range forecasting of flash floods and associated geomorphic processes, including their societal impacts.
Contributions related to the floods that occured in July 2021 in Germany and Western Europe, and in October 2020 in France and Italy (Alex storm) are particularly encouraged this year.
Contributions on the following scientific themes are specifically expected:
- Monitoring and nowcasting of heavy precipitation events based on radar and remote sensing (satellite, lightning, etc.) to complement rain gauge networks;
- Short-range (0-6h) heavy precipitation forecasting based on NWP models, with a focus on seamless forecasting strategies and ensemble strategies for the representation of uncertainties;
- Understanding and modeling of flash floods and associated geomorphic processes at appropriate space-time scales;
- Development of integrated hydro-meteorological forecasting chains and new modeling approaches for predicting flash floods and/or rainfall-induced geomorphic hazards in gauged and ungauged basins;
- New direct and indirect (proxy data) observation techniques and strategies for the observation or monitoring of hydrological reactions and geomorphic processes, and the validation of forecasting approaches;
- Development of impact-based modeling and forecasting approaches, including inundation mapping and/or specific impacts modeling approaches for the representation of societal vulnerability.
Urban hydrological processes are characterized by high spatial variability and short response times resulting from a high degree of imperviousness. Therefore, urban catchments are especially sensitive to space-time variability of precipitation at small scales. High-resolution precipitation measurements in cities are crucial to properly describe and analyses urban hydrological responses. At the same time, urban landscapes pose specific challenges to obtaining representative precipitation and hydrological observations.
This session focuses on high-resolution precipitation and hydrological measurements in cities and on approaches to improve modeling of urban hydrological response, including:
- Novel techniques for high-resolution precipitation measurement in cities and for multi-sensor data merging to improve the representation of urban precipitation fields.
- Novel approaches to hydrological field measurements in cities, including data obtained from citizen observatories.
- Precipitation modeling for urban applications, including convective permitting models and stochastic rainfall generators.
- Novel approaches to modeling urban catchment properties and hydrological response, from physics-based, conceptual and data-driven models to stochastic and statistical conceptualization.
- Applications of measured precipitation fields to urban hydrological models to improve hydrological prediction at different time horizons to ultimately enable improved management of urban drainage systems (including catchment strategy development, flood forecasting and management, real-time control, and proactive protection strategies aimed at preventing flooding and pollution).
- Strategies to deal with upcoming challenges, including climate change and rapid urbanization.

Extreme hydro-meteorological events drive many hydrologic and geomorphic hazards, such as floods, landslides and debris flows, which pose a significant threat to modern societies on a global scale. The continuous increase of population and urban settlements in hazard-prone areas in combination with evidence of changes in extreme weather events lead to a continuous increase in the risk associated with weather-induced hazards. To improve resilience and to design more effective mitigation strategies, we need to better understand the aspects of vulnerability, risk, and triggers that are associated with these hazards.
This session aims at gathering contributions dealing with various hydro-meteorological hazards that address the aspects of vulnerability analysis, risk estimation, impact assessment, mitigation policies and communication strategies. Specifically, we aim to collect contributions from academia, the industry (e.g. insurance) and government agencies (e.g. civil protection) that will help identify the latest developments and ways forward for increasing the resilience of communities at local, regional and national scales, and proposals for improving the interaction between different entities and sciences.
Contributions focusing on, but not limited to, novel developments and findings on the following topics are particularly encouraged:
- Physical and social vulnerability analysis and impact assessment of hydro-meteorological hazards
- Advances in the estimation of socioeconomic risk from hydro-meteorological hazards
- Characteristics of weather and precipitation patterns leading to high-impact events
- Relationship between weather and precipitation patterns and socio-economic impacts
- Hazard mitigation procedures
- Strategies for increasing public awareness, preparedness, and self-protective response
- Impact-based forecast, warning systems, and rapid damage assessment.
- Insurance and reinsurance applications

Hydro-meteorological extremes such as floods, droughts, storms, or heatwaves often affect large regions therefore causing large damages and costs. Hazard and risk assessments, aiming at reducing the negative consequences of such extreme events, are often performed with a focus on one location despite the spatially compounding nature of extreme events. While spatial extremes receive a lot of attention by the media, little is known about their driving factors and it remains challenging to assess their risk by modelling approaches. Key challenges in advancing our understanding of spatial extremes and in developing new modeling approaches include the definition of multivariate events, the quantification of spatial dependence, the dealing with large dimensions, the introduction of flexible dependence structures, the estimation of their probability of occurrence, the identification of potential drivers for spatial dependence, and linking different spatial scales. This session invites contributions which help to better understand processes governing spatial extremes and/or propose new ways of describing and modeling spatially compounding events at different spatial scales.

This session brings together scientists, forecasters, practitioners and stakeholders interested in exploring the use of ensemble hydro-meteorological forecast techniques in hydrological applications: e.g., flood control and warning, reservoir operation for hydropower and water supply, transportation, and agricultural management. It will address the understanding of sources of predictability and quantification and reduction of predictive uncertainty of hydrological extremes in deterministic and ensemble hydrological forecasting. Uncertainty estimation in operational forecasting systems is becoming a more common practice. However, a significant research challenge and central interest of this session is to understand the sources of predictability and development of approaches, methods and techniques to enhance predictability (e.g. accuracy, reliability etc.) and quantify and reduce predictive uncertainty in general. Ensemble data assimilation, NWP preprocessing, multi-model approaches or hydrological postprocessing can provide important ways of improving the quality (e.g. accuracy, reliability) and increasing the value (e.g. impact, usability) of deterministic and ensemble hydrological forecasts. The models involved with the methods for predictive uncertainty, data assimilation, post-processing and decision-making may include machine learning models, ANNs, catchment models, runoff routing models, groundwater models, coupled meteorological-hydrological models as well as combinations (multimodel) of these. Demonstrations of the sources of predictability and subsequent quantification and reduction in predictive uncertainty at different scales through improved representation of model process (physics, parameterization, numerical solution, data support and calibration) and error, forcing and initial state are of special interest to the session.

Drought and water scarcity are important issues in many regions of the Earth. While the projected increase in the severity and frequency of droughts can lead to water scarcity situations, particularly in regions that are already water-stressed, overexploitation of available water resources can exacerbate the consequences of droughts. In the worst case, this can lead to long-term environmental and socio-economic impacts. Drought Monitoring and Forecasting are recognized as one of three pillars of effective drought management, and it is, therefore, necessary to improve both monitoring and sub-seasonal to seasonal forecasting for droughts and water availability and to develop innovative indicators and methodologies that translate the information provided into effective drought early warning and risk management. This session addresses statistical, remote sensing and physically-based techniques, aimed at monitoring, modelling and forecasting hydro-meteorological variables relevant to drought and/or water scarcity. These include, but are not limited to, precipitation, snow cover, soil moisture, streamflow, groundwater levels, and extreme temperatures. The development and implementation of drought indicators meaningful to decision-making processes, and ways of presenting and integrating these with the needs and knowledge of water managers, policymakers and other stakeholders, are further issues that are addressed. The session aims to bring together scientists, practitioners and stakeholders in the fields of hydrology and meteorology, as well as in the field of water resources and/or drought risk management, also including drought and water scarcity interrelationship, hydrological impacts, and feedbacks with society. Particularly welcome are applications and real-world case studies in regions subject to significant water stress, where the importance of drought warning, supported through state-of-the-art monitoring and forecasting of water resources availability, is likely to become more important in the future.
With recent extreme events reaching far beyond existing records, such as the Pacific Northwest heat wave and severe flooding in Western Europe, eastern US and across China, the discussion to what extent we are prepared for unprecedented extremes and whether existing methods and models are able to capture them has flared up. It is becoming increasingly essential to understand and quantify plausible rare, high-impact events for risk management and adaptation.
Methods to understand and evaluate low-likelihood extreme events have seen substantial advancements over the recent years. Event attribution studies are now providing rapid analyses of unprecedented extreme events; physical climate storylines are developed to evaluate plausible rather than likely events; causal inference is used to understand drivers of very rare events; near-miss events and potential analogues in space, historical and paleo archives are evaluated; spatial extreme value analysis and machine learning methods are applied, large ensembles representing various outcomes are generated, such as Single Model Initial-condition Large Ensembles (SMILEs); and weather prediction systems are increasingly being employed, such as the through the UNprecedented Simulated Extremes using ENsembles (UNSEEN) approach.
This session aims to bring together communities from weather prediction, climate projection, hydrology to impact and risk management, and to learn from the variety of methods to understand and quantify low-likelihood extreme events in the present and future climate. The session welcomes contributions at all temporal and spatial scales, and all types of extremes and invites novel methods – including downward counterfactuals and causal inference – as well as new results on unforeseen climate risks – including those from compound events and low-likelihood high-warming outcomes.

This interactive session aims to bridge the gap between science and practice in operational forecasting for different climate and water-related natural hazards including their dynamics and interdependencies. Operational (early) warning systems are the result of progress and innovations in the science of forecasting. New opportunities have risen in physically based modelling, coupling meteorological and hydrological forecasts, ensemble forecasting, impact-based forecasting and real time control. Often, the sharing of knowledge and experience about developments are limited to the particular field (e.g. flood forecasting or landslide warnings) for which the operational system is used. Increasingly, humanitarian, disaster risk management and climate adaptation practitioners are using forecasts and warning information to enable anticipatory/ early action that saves lives and livelihoods. It is important to understand their needs, their decision-making process and facilitate their involvement in forecasting and warning design and implementation (co-development).
The focus of this session will be on bringing the expertise from different fields together as well as exploring differences, similarities, problems and solutions between forecasting systems for varying hazards including climate emergency. Real-world case studies of system implementations - configured at local, regional, national, continental and global scales - will be presented, including trans-boundary issues. An operational warning system can include, for example, monitoring of data, analysing data, making and visualizing forecasts, giving warning signals and suggesting early action and response measures.
Contributions are welcome from both scientists and practitioners who are involved in developing and using operational forecasting and/or management systems for climate and water-related hazards, such as flood, drought, tsunami, landslide, hurricane, hydropower, pollution etc. We also welcome contributions from early career practitioners and scientists.

It becomes increasingly accepted that many regions all over the world are experiencing an increase in the frequency of extreme rainfall events and potentially in their properties. For predicting the impact of future climate change on the landscape, it is therefore vital to understand the dynamics of surface processes under extreme events. Furthermore, focusing on the conditions necessary for extreme events to occur can provide key insights into past changes in climate at different time scales. Extreme storms cause a multitude of hydrogeomorphic and natural hazards responses, including floods and respective fluvial responses, hillslope erosion and failures, and debris flows from slopes into fluvial systems. Measuring, evaluating, and predicting the impacts of extreme rainstorms, however, remains challenging due to the difficult-to-predict and complex nature of storms and rainfall-surface interactions.
This interdisciplinary session focuses on the causative chain which links the deterministic and mostly stochastic nature of the synoptic to meso/regional and watershed scales of extreme storms, to their respective transformation into watershed, slope, and stream hydrology, and to their geomorphic impact. We welcome studies from all the parts of this chain, from all climates, and at all temporal scales, that are focusing on the hydrological responses to extreme events and on their imprints on the landscape through erosion and sediment movement. We favor studies with emphasis on the final noticeable impact of extreme events on the landscape and/or on the integrated long-term consequences of extreme storm regime on landscape evolution. Especially, we encourage studies presenting new physical/stochastic modeling approaches that explicitly investigated the impact of extreme events on the landscape.

Low-lying coastal areas can be an early casualty to sea-level rise, especially where enhanced by land subsidence. An ever increasing number of studies indicates that land subsidence due to natural and anthropogenic causes has induced damage to wetland ecosystems in many countries worldwide, and has increased flooding hazard and risk. Coastal subsidence causes include excessive groundwater extraction from aquifers, peat oxidation due to surface water drainage through land reclamation, urbanization and agricultural use, as well as sediment starvation due to construction of dams and artificial levees. Contrary to the global processes behind sea-level rise, natural and anthropogenic coastal subsidence is primarily a local phenomenon, and its causes and severity may vary substantially from place to place.
The combination of geological and historical measurements with remote sensing data is required to understand all drivers of coastal vertical land motion and the contributions to past, present, and future subsidence.
Understanding coastal subsidence requires multidisciplinary expertise, models, and remote and in-situ observations from geology, geodesy, natural hazards, oceanography, hydrogeology, and geomechanics. In this session, we aim to bring together all the involved disciplines. We invite contributions on all aspects of coastal subsidence research and applications, including recent advances on: i) measurement through ground-based, aerial and satellite remote sensing techniques, ii) numerical models and future projections, iii) their applicability to distinguish between the different drivers contributing to land subsidence, and iv) quantification of coastal hazards associated with relative sea-level rise. In particular, efforts towards characterizing human intervention on coastal vertical land motion are welcomed.

Transport of sediments in geophysical flows occurs in mountainous, fluvial, estuarine, coastal, aeolian and other natural or man-made environments on Earth, while also shapes the surface of planets such as Mars, Titan, and Venus. Understanding the motion of sediments is still one of the most fundamental problems in hydrological and geophysical sciences. Such processes can vary across a wide range of scales - from the particle to the landscape - which can directly impact both the form (geomorphology) and, on Earth, the function (ecology and biology) of natural systems and the built infrastructure surrounding them. In particular, feedback between flow and sediment transport as well as interparticle interactions including size sorting are a key processes in surface dynamics, finding a range of important applications, from hydraulic engineering and natural hazard mitigation to landscape evolution and river ecology.
Specific topics of interest include (but are not restricted to):
A) particle-scale interactions and transport processes:
-mechanics of entrainment and disentrainment (for fluvial and aeolian flows)
-momentum (turbulent impulses) and energy transfer between turbulent flows and particles
-upscaling and averaging techniques for stochastic transport processes

B) reach-scale sediment transport and geomorphic processes
-bedform generation, evolution and disintegration dynamics (e.g. for dunes and other formations)
-discrete element modelling of transport processes and upscaling into continuum frameworks
-derivation and solution of equations for multiphase flows (including fluvial and aeolian flows)
-shallow water hydro-sediment-morphodynamic processes
C) large-scale, highly unsteady and complex water-sediment flows:
-flash floods, debris flows and landslides due to extreme rainfall
-natural and build dam failures and compound disasters (due to landslides, debris flow intrusion and downstream flooding)

Sediment transport is a fundamental component of all geomorphic systems (including fluvial, aeolian, coastal, hillslopes and glacial), yet it is something that we still find surprisingly difficult both to monitor and to model. Robust data on where and how sediment transport occurs are needed to address outstanding research questions, including the spatial and temporal controls on critical shear stress, the influence of varying grain size distributions, and the impact of large magnitude events. Recent developments have provided a) new opportunities for measuring sediment transport in the field; and b) new ways to represent sediment transport in both physical laboratory models and in numerical models. These developments include (but are not limited to) the application of techniques such as seismic and acoustic monitoring, 3D imaging (e.g. CT and MRI scanning), deployment of sensors such as accelerometers, replication of field topography using 3D printing, use of luminescence as a sediment tracer, remote sensing of turbidity, discrete numerical modelling, and new statistical approaches.
In this session we welcome contributions from all areas of geomorphology that develop new methods for monitoring and modelling all types of sediment transport, or that showcase an application of such methods. Contributions from ECRs and underrepresented groups are particularly encouraged.

Volcanoes play an essential role in society through their impacts on human
life, infrastructure, and the environment. Those in marine settings pose
hazards, such as the awakening of submarine volcanoes, underwater
explosions, and sudden release of harmful gases from the volcano or
overlying water column, and tsunami inundation of neighboring coastlines
due to caldera collapse, submarine landslides, or entry of pyroclastic
flows into the sea. Specifically, volcanic degassing plays a dominant role
in forcing the timing and nature of volcanic unrest and eruptions in such
settings. On the other hand, quiescent passive degassing and
smaller-magnitude eruptions can impact the regional climate system. For
those reasons understanding the exsolution processes of gas species
dissolved in magma and measuring their emissions is crucial to
characterize the eruptive mechanism and evaluate the subsequent impacts on
the atmospheric composition, the environment, and the biosphere.
The session will be focused on multidisciplinary monitoring volcanic
environments, including in the vicinity of cities and highly touristic areas. Since
gas emissions are measured and monitored via in-situ and remote sensing
techniques, we invite contributions to studies that gain insights into the
subterranean-surface processes and quantify their impacts. In addition, we
encourage studies that focus on modelling the subsurface and
atmospheric/climatic processes and laboratory experiments that are
fundamental to the interpretation of field-based and satellite
observations. Finally, we will undoubtedly discuss the ability to
recognize the hazards and their impact on people, emergency management by
civil protection authorities, community education, case studies and risk
mitigation to reduce the effects of volcanism and its societal impact.

The session deals with the documentation and modelling of the tectonic, deformation and geodetic features of any type of volcanic area, on Earth and in the Solar System. The focus is on advancing our understanding on any type of deformation of active and non-active volcanoes, on the associated behaviours, and the implications for hazards. We welcome contributions based on results from fieldwork, remote-sensing studies, geodetic and geophysical measurements, analytical, analogue and numerical simulations, and laboratory studies of volcanic rocks.
Studies may be focused at the regional scale, investigating the tectonic setting responsible for and controlling volcanic activity, both along divergent and convergent plate boundaries, as well in intraplate settings. At a more local scale, all types of surface deformation in volcanic areas are of interest, such as elastic inflation and deflation, or anelastic processes, including caldera and flank collapses. Deeper, sub-volcanic deformation studies, concerning the emplacement of intrusions, as sills, dikes and laccoliths, are most welcome.
We also particularly welcome geophysical data aimed at understanding magmatic processes during volcano unrest. These include geodetic studies obtained mainly through GPS and InSAR, as well as at their modelling to imagine sources.
The session includes, but is not restricted to, the following topics:
volcanism and regional tectonics;
formation of magma chambers, laccoliths, and other intrusions;
dyke and sill propagation, emplacement, and arrest;
earthquakes and eruptions;
caldera collapse, resurgence, and unrest;
flank collapse;
volcano deformation monitoring;
volcano deformation and hazard mitigation;
volcano unrest;
mechanical properties of rocks in volcanic areas.
Developing physical-mathematical models able to describe the evolution of eruptive phenomena is a key point in volcanology. In the case of high-risk phenomena, such as lava flows or ash dispersal, predicting their spatial and temporal evolution and determining the potentially affected areas is fundamental in supporting every action directed at mitigating the risk as well as for environmental planning.
This session aims to address unresolved challenging questions related to complex geophysical flow modeling and simulation, gathering physical-mathematical models, numerical methods and field and satellite data analysis in order to: (i) expand knowledge of complex volcanic processes and their space-time dynamics; (ii) monitor and model volcanic phenomena; (iii) evaluate model robustness through validation against real case studies, analytical solutions and laboratory experiments; (iv) quantify the uncertainty propagation through both forward (sensitivity analyses) and inverse (optimization/calibration) modelling in all components of volcanic hazard modelling in response to eruptive crises.
Glaciers and volcanoes interact in a number of ways, including instances where volcanic/geothermal activity alters glacier dynamics or mass balance, via subglacial eruptions or the deposition of supraglacial tephra. Glaciers can also impact volcanism, for example by directly influencing mechanisms of individual eruptions resulting in the construction of distinct edifices. Glaciers may also influence patterns of eruptive activity when mass balance changes adjust the load on volcanic systems, the water resources and hydrothermal systems. However, because of the remoteness of many glacio-volcanic environments, these interactions remain poorly understood.
In these complex settings, hazards associated with glacier-volcano interaction can vary from lava flows to volcanic ash, lahars, landslides, pyroclastic flows or glacial outburst floods. These can happen consecutively or simultaneously and affect not only the earth, but also glaciers, rivers and the atmosphere. As accumulating, melting, ripping or drifting glaciers generate signals as well as degassing, inflating/ deflating or erupting volcanoes, the challenge is to study, understand and ultimately discriminate these potentially coexisting signals. We wish to fully include geophysical observations of current and recent events with geological observations and interpretations of deposits of past events. Glaciovolcanoes also often preserve a unique record of the glacial or non-glacial eruptive environment that is capable of significantly advancing our knowledge of how Earth's climate system evolves.
We invite contributions that deal with the mitigation of the hazards associated with ice-covered volcanoes in the Arctic, Antarctic or globally, that improve the understanding of signals generated by ice-covered volcanoes, or studies focused on volcanic impacts on glaciers and vice versa. Research on recent activity is especially welcomed. This includes geological observations e.g. of deposits in the field or remote-sensing data, together with experimental and modelling approaches. We also invite contributions from any part of the world on past activity, glaciovolcanic deposits and studies that address climate and environmental change through glaciovolcanic studies. We aim to bring together scientists from volcanology, glaciology, seismology, geodesy, hydrology, geomorphology and atmospheric science in order to enable a broad discussion and interaction.

The Fagradalsfjall eruption on the Reykjanes Peninsula of Iceland started on 19 March 2021. It provides a unique opportunity to study all aspects of a low-intensity effusive basaltic eruption in great detail using multidisciplinary approaches. The Fagradalsfjall eruption followed a several-week long period of intense seismicity and deformation associated with formation of the feeding dike. The eruption terminated on September 18, 2021, after producing a lava field covering about 4.5 km2. The eruption progressed through several phases, each characterized by different emission sources, eruptive style, intensities, and associated hazards. The eruption may be representative of the formation of a shield volcano, a process that the scientific community has had limited chances to observe in real time.
We welcome submissions on sustained low-intensity basaltic eruptions including (but not limited to) the 2021 Fagradalsfjall eruption; their plumbling systems, eruptive products, and impacts. We particularly encourage comparative studies across different regions that may help us to better understand the volcanic processes that are active in the Fagradalsfjall eruption.
Topics may include, for example: physical volcanology of eruptive products and eruptive behavior; lava flow modeling; acoustic studies; petrology; geochemistry and interaction with groundwater; studies of volcanic gases; crustal deformation; seismology; volcano monitoring; social effects; health effects; hazard mitigation; tectonic implications; volcano-tectonic interactions; atmosphere-climate interactions, etc.

Over the past few years, major technological advances significantly increased both the spatial coverage and frequency bandwidth of multi-disciplinary observations at active volcanoes. Networks of instruments, both ground- and satellite-based, now allow for the quantitative measurement of geophysical responses, geological features and geochemical emissions, permitting an unprecedented, multi-parameter vision of the surface manifestations of mass transport beneath volcanoes. Furthermore, new models and processing techniques have led to innovative paradigms for inverting observational data to image the structures and interpret the dynamics of volcanoes. In particular, machine learning, a type of AI in which computers learn from data, is gaining importance in volcanology, not only for monitoring purposes (i.e., in real-time) but also for later hazards analysis (e.g. modelling tools).
Within this context, this session aims to bring together a multidisciplinary audience to discuss the most recent innovations in volcano imaging and monitoring, and to present observations, methods and models that increase our understanding of volcanic processes.
We welcome contributions (1) related to methodological and instrumental advances in geophysical, geological and geochemical imaging of volcanoes, (2) to explore new knowledge provided by these studies on the internal structure and physical processes of volcanic systems, and (3) to investigate the potential of machine learning techniques to process multispectral satellite data for developing a better understanding of volcanic hazards.
We invite contributors from all geophysical, geological and geochemical disciplines: seismology, electromagnetics, geoelectrics, gravimetry, magnetics, muon tomography, volatile measurements and analysis. The session will include in-situ monitoring and high- resolution remote sensing studies that resolve volcanic systems ranging from near-surface hydrothermal activity to deep magma migration.

Volcanic islands are simultaneously some of the tallest and fastest-forming geological features on Earth and constitute the site of significant geohazards ranging from volcanic eruptions, earthquakes, landslides, and tsunamis. Ocean island volcanoes are also some of the most enigmatic features in our planet, as their genesis is still not satisfactorily explained by conventional plate tectonics. The scientific community faces several challenges in studying volcanic islands, particularly in what regards processes taking place at depth. There is still a need to densify seismic networks in volcanic islands, using both land- and seafloor-based stations, to record the signals associated with volcanic and tectonic processes and automatically or manually detect and classify those signals. 3D images from the shallow crust to the deep mantle are crucial to unravel the geodynamic processes behind the generation of volcanism. More accurate quantification of temporal changes in the volcanic systems will help in the forecasting of potential eruptions and the monitoring of existing ones. On top of that, the presence of geothermal systems and induced seismicity from industrial exploration are also critical challenges in volcanic islands due to the system's complexity.
Considering the enormous diversity of interactions in volcanic islands, we welcome contributions from a wide range of studies including: seismo-volcanic monitoring and tracking of magma movements; characterization and location of volcanic tremor; 3D and 4D seismic imaging, including attenuation tomography; seismic ambient noise monitoring; machine learning to detect and classify volcanic earthquakes; active source studies to characterize volcanic flanks and landslides; induced and triggered seismicity in geothermal systems; and seismic sources.

This session is devoted to the most recent eruption of the Cumbre Vieja volcano, which started on Sept. 19, 2021, on the island of La Palma after 50 years of repose. Volcanic unrest was recorded in Oct. 2017, when a seismic swarm was located at more than 20 km depths. Nine additional swarms followed, the last one was recorded in June 2021. Geochemical anomalies followed this increased seismicity indicating a magmatic recharge at depth. On Sept. 11, 2021, a new seismic swarm was observed at shallower depths (10-12 km), indicating a possible magmatic intrusion. This was confirmed when geodetic monitoring networks on the island started showing clear signs of inflation. The seismicity increased in frequency and intensity with many felt earthquakes. Seismic activity accelerated in the morning of Sept. 19 when a strong shallow earthquake was widely felt on the western part of the island. This was the precursor of the eruption, which started at about 14:10 UTC on the same day. A series of vents opened along a fissure close to Los Llanos on the western flank of Cumbre Vieja volcano. The eruption displayed vigorous lava fountaining and powerful Strombolian explosions while lava effusion produced a compound Aa flow field. The eruption has destroyed hundreds of buildings, plantations as well as cutting vital transport routes.
This session is open to contributions aimed at geological, geophysical, geochemical and volcanological studies of the eruption and its precursors and, more in general, to studies that can help better understanding the eruptive dynamics. We also welcome contributions focused on the management of scientific communication during this crisis and the management of the volcanic emergency.

Volcanoes are inherently complex and dynamic geological system, acting as the source of diverse sediment types and as a control on varied sediment transport processes within surrounding environments, both during and after their life. This can manifest as an accumulation of thick primary volcaniclastic sequences from pyroclastic (e.g. pyroclastic density currents, tephra falls), laharic and flank instability processes, secondary volcaniclastic sequences from the reworking/redeposition (or both) of primary deposits and their interaction with non-volcanic sedimentary processes, or deposits from the weathering of lava flows. The diversity of processes that may be involved in the generation of volcaniclastic sequences makes often difficult to describe and interpret them. As the comprehension of the generation, transportation and accumulation mechanisms of volcaniclastic sequences is of extreme importance for natural hazard and economic perspectives, to reduce uncertainties and move forward in the identification of volcano-sedimentary processes and potential effects, modern and ancient volcaniclastic sequences must be studied and interpreted hand in hand. Thus, the proposed session aims to bring together studies that explore the volcaniclastic record of modern and ancient environments. Contributions are welcomed in areas including, but not limited to, the identification of volcanic features in ancient sedimentary records, multidisciplinary (e.g., stratigraphic, petrographic, geophysical) approaches to the study of modern subaerial and submarine volcaniclastic sequences as analogue sites, and examples of the modification of sedimentary systems across syn- and inter-eruptive periods.

Debris flows are among the most dangerous natural hazards that threaten people and infrastructures in both mountainous and volcanic areas. The study of the initiation and dynamics of debris flows, along with the characterization of the associated erosion/deposition processes, is of paramount importance for hazard assessment, land-use planning and design of mitigation measures, including early warning systems. In addition, the impacts of climate change on debris-flow activity must be considered and carefully analysed, as the number of mountain areas prone to these events may increase in future.
A growing number of scientists with diverse backgrounds are studying debris flows and lahars. The difficulties in measuring parameters related to their initiation and propagation have progressively prompted research into a wide variety of laboratory experiments and monitoring studies. However, there is a need of improving the quality of instrumental observations that would provide knowledge for more accurate hazards maps and modeling. Nowadays, the combination of distributed sensor networks and remote sensing techniques represents a unique opportunity to gather direct observations of debris flows to better constrain their physical properties.
Scientists working in the field of debris flows are invited to present their recent advancements. In addition, contributions from practitioners and decision makers are also welcome. Topics of the session include: field studies and documentation, mechanics of debris-flow initiation and propagation, laboratory experiments, modeling, monitoring, impacts of climate change on debris-flow activity, hazard and risk assessment and mapping, early warning, and alarm systems.
Global warming is unequivocal: the frequency and intensity of heavy precipitation events increased since the mid-20th century in all regions in which observational data were sufficient for trend analysis. And heavy precipitations and related effects are projected to intensify and be more frequent in most regions.
In this framework, particular attention should be paid to all the ground events triggered by rainfall, among which landslides and soil erosion.
Changes in temperature also have been shown to affect the hydraulic and mechanical behavior of soils and rocks in multiple ways, suggesting the importance of monitoring and modelling thermal variables alongside the hydraulic ones.
The influence of climate variables on the triggering, frequency, and severity of slope failures and soil erosion can be different according to the area, the time horizon of interest, and the specific trends of weather variables. Similarly, land use/cover change can play a pivotal role in exacerbating or reducing such hazards.
Thus, the overall impacts depend on the region, spatial scale, time frame, and socio-economic context addressed. However, even the simple identification of the weather patterns regulating the occurrence of such phenomena represents a not trivial issue, also assuming steady conditions, due to the crucial role played by geomorphological details. To support hazards’ monitoring, predictions, and projections, last-generation and updated datasets with high spatio-temporal resolution and quality - as those from the Copernicus Services’ Portals - are useful to feed models, big-data analytics, and indicators’ frameworks enabling timely, robust, and efficient decision making.
The Session aims at presenting studies concerning ongoing to future analysis on the impact of climate change on landslide triggering and dynamics, and soil erosion hazard, across different geographical contexts and scales. Either investigations including analyses of historical records and related climate variables, or modeling approaches driven by future climate exploiting downscaled output of climate projections are welcome. Studies assessing variations in severity, frequency, and/or timing of events and consequent risks are valuable.
Moreover, a focus on all aspects of landslide thermo-hydro-mechanics, from experimental studies to field and remote-sensing monitoring, from microstructural analyses to geomechanical modelling at various spatial and temporal scales, is proposed.
Rockfalls, rockslides and rock avalanches are among the primary hazards and drivers of landscape evolution in steep terrain. The physics of rock slope degradation and dynamics of failure and transport mechanisms define the hazards and possible mitigation strategies and enable retrodictions and predictions of events and controls.
This session aims to bring together state-of-the-art methods for predicting, assessing, quantifying, and protecting against rock slope hazards across spatial and temporal scales. We seek innovative contributions from investigators dealing with all stages of rock slope hazards, from weathering and/or damage accumulation, through detachment, transport and deposition, and finally to the development of protection and mitigation measures. In particular, we seek studies presenting new theoretical, numerical or probabilistic modelling approaches, novel data sets derived from laboratory, in situ, or remote sensing applications, and state-of-the-art approaches to social, structural, or natural protection measures. We especially encourage contributions from geomechanics/rock physics, geodynamics, geomorphology and tectonics to better understand how rockfall, rockslides and rock avalanches act across scales.

Landslides are ubiquitous geomorphological phenomena with potentially catastrophic consequences. In several countries, landslide mortality can be higher than that of any other natural hazard. Predicting landslides is a difficult task that is of both scientific interest and societal relevance that may help save lives and protect individual properties and collective resources. The session focuses on innovative methods and techniques to predict landslide occurrence, including the location, time, size, destructiveness of individual and multiple slope failures. All landslide types are considered, from fast rockfalls to rapid debris flows, from slow slides to very rapid rock avalanches. All geographical scales are considered, from the local to the global scale. Of interest are contributions investigating theoretical aspects of natural hazard prediction, with emphasis on landslide forecasting, including conceptual, mathematical, physical, statistical, numerical and computational problems, and applied contributions demonstrating, with examples, the possibility or the lack of a possibility to predict individual or multiple landslides, or specific landslide characteristics. Of particular interest are contributions aimed at: the evaluation of the quality of landslide forecasts; the comparison of the performance of different forecasting models; the use of landslide forecasts in operational systems; and investigations of the potential for the exploitation of new or emerging technologies e.g., monitoring, computational, Earth observation technologies, in order to improve our ability to predict landslides. We anticipate that the most relevant contributions will be collected in the special issue of an international journal.
Among the many mitigation measures available for reducing the risk to life related to landslides, early warning systems certainly constitute a significant option available to the authorities in charge of risk management and governance. Landslide early warning systems (LEWS) are non-structural risk mitigation measures applicable at different scales of analysis: slope and regional.
Independently by the scale of analysis, the structure of LEWS can be schematized as an interrelation of four main modules: setting, modelling, warning, response. However, the definition of the elements of these modules and the aims of the warnings/alerts issued considerably vary as a function of the scale at which the system is employed.
The session focuses on landslide early warning systems (LEWSs) at both regional and local scales. The session wishes to highlight operational approaches, original achievements and developments useful to operate reliable (efficient and effective) local and territorial LEWS. Moreover, the different schemes describing the structure of a LEWS available in literature clearly highlight the importance of both social and technical aspects in the design and management of such systems.
For the above-mentioned reasons, contributions addressing the following topics are welcome:
• rainfall thresholds definition for warning purposes;
• monitoring systems for early warning purposes;
• warning models for warning levels issuing;
• performance analysis of landslide warning models;
• communication strategies;
• emergency phase management;

The global increase in damaging landslide events has attracted the attention of governments, practitioners, and scientists to develop functional, reliable and (when possible) low cost monitoring strategies. Numerous case studies have demonstrated how a well-planned monitoring system of landslides is of fundamental importance for long and short-term risk reduction.
Today, the temporal evolution of a landslide is addressed in several ways, encompassing classical and more complex in situ measurements or remotely sensed data acquired from satellite and aerial platforms. All these techniques are adopted for the same final scope: measure landslide motion over time, trying to forecast future evolution or minimally reconstruct its recent past. Real time, near-real time and deferred time strategies can be profitably used for landslide monitoring, depending on the type of phenomenon, the selected monitoring tool, and the acceptable level of risk.
This session follows the general objectives of the International Consortium on Landslides, namely: (i) promote landslide research for the benefit of society, (ii) integrate geosciences and technology within the cultural and social contexts to evaluate landslide risk, and (iii) combine and coordinate international expertise.
Considering these key conceptual drivers, this session aims to present successful monitoring experiences worldwide based on both in situ and/or remotely sensed data. The integration and synergic use of different techniques is welcomed, as well as newly developed tools or data analysis approaches, including big data management strategies. Specifically, a thematic focus will be on applications combining satellite, aerial or ground remote sensing with geophysical data such as electrical, seismic or electromagnetic surveys. The session is expected also to present case studies in which multi-temporal and multi-platform monitoring data are exploited for risk management and Civil Protection aims with positive effects in both social and economic terms.
Rock deformation at different stress levels in the brittle regime and across the brittle-ductile transition is controlled by damage processes occurring on different spatial scales, from grain scale to fractured rock masse. These lead to a progressive increase of micro- and meso-crack intensity in the rock matrix and to the growth of inherited macro-fractures at rock mass scale. Coalescence of these fractures forms large-scale structures such as brittle fault zones and deep-seated rock slide shear zones. Diffuse or localized rock damage have a primary influence on rock properties (strength, elastic moduli, hydraulic and electric properties) and their evolution across multiple temporal scales spanning from geological times to highly dynamic phenomena as earthquakes, volcanic eruptions and landslides. In subcritical stress conditions, damage accumulation results in brittle creep processes key to the long-term evolution of geophysical, geomorphological and geo-engineering systems.
Damage and progressive failure processes must be considered to understand the time-dependent hydro-mechanical behaviour of faults (e.g. stick-slip vs aseismic creep), volcanic systems and slopes (e.g. slow rock slope deformation vs catastrophic rock slides), as well as the response of rock masses to stress perturbations induced by artificial excavations (tunnels, mines) and static or dynamic loadings. At the same time, damage processes control the brittle behaviour of the upper crust and are strongly influenced by intrinsic rock properties (strength, fabric, porosity, anisotropy), geological structures and their inherited damage, as well as by the evolving pressure-temperature with increasing depth and by fluid pressure, transport properties and chemistry. However, many complex relationships between these factors and rock damage are yet to be understood.
In this session we will bring together researchers from different communities interested in a better understanding of rock damage processes and consequence. We welcome innovative contributions on experimental studies (both in the laboratory and in situ), continuum / micromechanical analytical and numerical modelling, and applications to fault zones, reservoirs, slope instability and landscape evolution, and engineering applications. Studies adopting novel approaches and combined methodologies are particularly welcome.
Denudational hillslope and fluvial processes, associated source-to-sink fluxes and sedimentary budgets are controlled by a range of environmental drivers and anthropogenic activities, exacerbated by the consequences of climate change. A better understanding of the drivers, mechanisms and rates of contemporary denudational hillslope and fluvial processes as well as of the sediment and hydrological connectivity across a range of different spatio-temporal scales and climatic zones has significant societal implications for water quality, hydraulic infrastructures, aquatic ecosystems, public safety, and biogeochemical cycles.
The session aims to bring together interdisciplinary researchers working across field, experimental, numerical modelling, remote sensing, and dating approaches who are advancing methods and providing new insights into: (i) slope mass movements (e.g., landslides, rockfalls, and debris flows) and related hazard cascades in mountainous environments; (ii) water, sediment and solute source-to-sink processes in different climate zones (e.g., cold climate, temperate, arid and tropical regions) from small headwaters to large river systems at event, seasonal, and multi-decadal scales; and (iii) the anthropogenic impacts and societal implications of changing hillslope and fluvial processes and possible solutions for future sustainable management.
We encourage the participation of early-career researchers and PhD students working in the fields of geomorphology, hydrology, hazard, glaciers, permafrost, and aquatic ecosystems, as we aim to expand and integrate the network of researchers addressing this complex subject across scientific disciplines.

From the real-time integration of multi-parametric observations is expected the major contribution to the development of operational t-DASH systems suitable for supporting decision makers with continuously updated seismic hazard scenarios. A very preliminary step in this direction is the identification of those parameters (seismological, chemical, physical, biological, etc.) whose space-time dynamics and/or anomalous variability can be, to some extent, associated with the complex process of preparation of major earthquakes.
This session wants then to encourage studies devoted to demonstrate the added value of the introduction of specific, observations and/or data analysis methods within the t-DASH and StEF perspectives. Therefore, studies based on long-term data analyses, including different conditions of seismic activity, are particularly encouraged. Similarly welcome will be the presentation of infrastructures devoted to maintain and further develop our present observational capabilities of earthquake related phenomena also contributing in this way to build a global multi-parametric Earthquakes Observing System (EQuOS) to complement the existing GEOSS initiative.
To this aim this session is not addressed just to seismology and natural hazards scientists but also to geologist, atmospheric sciences and electromagnetism researchers, whose collaboration is particular important for fully understand mechanisms of earthquake preparation and their possible relation with other measurable quantities. For this reason, all contributions devoted to the description of genetic models of earthquake’s precursory phenomena are equally welcome.

Earthquake disaster mitigation involves different elements, ranging from analysis of hazards (e.g. physical description of ground shaking) to its impact on built and natural environment, from vulnerability and exposure to hazards to capacity building and resilience, from long-term preparedness to post-event response. The scientific base of this process involves various seismic hazard/risk models, developed at different time scales and by different methods, as well as the use of heterogeneous observations and multi-disciplinary information. Accordingly, we welcome contributions about different types of seismic hazards research and assessments, both methodological and practical, and their applications to disaster risk reduction in terms of physical and social vulnerability, capacity and resilience.
This session aims to tackle theoretical and implementation issues, as well as aspects of communication and science policy, which are all essential elements towards effective disasters mitigation, and include:
⇒ development of physical/statistical models for the different earthquake risk components (hazard, exposure, vulnerability), including novel methods for data collection and processing (e.g. statistical machine learning analysis)
⇒ earthquake hazard and risk estimation at different time and space scales, including their performance verification against observations (including unconventional seismological observations);
⇒ time-dependent seismic hazard and risk assessments (including contribution of aftershocks), and post-event information (early warning, alerts) for emergency management;
⇒ earthquake-induced cascading effects (e.g. landslides, tsunamis, etc) and multi-risk assessment (e.g. earthquake plus flooding).
The interdisciplinary session will provide an opportunity to share best practices and experience gained with different methods, providing opportunities to advance our understanding of disaster risk in "all its dimensions of vulnerability, capacity, exposure of persons and assets, hazard characteristics and the environment", while simultaneously highlighting existing gaps and future research directions.
New models based on seismicity patterns, considering their physical meaning and their statistical significance, shed light on the preparation process of large earthquakes and on the evolution in time and space of clustered seismicity.
Opportunities for improved model testing are being opened by the increasing amount of earthquake data available on local to global scales, together with accurate assessments of the catalogues’ reliability in terms of location precision, magnitude of completeness and coherence in magnitude determination.
Moreover, it is possible to reliably integrate the models with additional information, like geodetic deformation, active fault data, source parameters of previously recorded seismicity, fluid contents, tomographic information, or laboratory and numerical experiments of rock fracture and friction. Such integration allows a detailed description of the system and hopefully an improved forecasting of the future distribution of seismicity in space, time and magnitude.
In this session, we invite researchers to submit their latest results and insights on the physical and statistical models and machine learning approaches for the space, time and magnitude evolution of earthquake sequences. Particular emphasis will be placed on:
• physical and statistical models of earthquake occurrence;
• analysis of earthquake clustering;
• spatial, temporal and magnitude properties of earthquake statistics;
• quantitative testing of earthquake occurrence models;
• reliability of earthquake catalogues;
• time-dependent hazard assessment;
• methods for earthquake forecasting;
• data analyses and requirements for model testing;
• pattern recognition in seismology;
• machine learning applied to seismic data; and
• methods for quantifying uncertainty in pattern recognition and machine learning.

The main concern of the occurrence of an earthquake is the ground shaking, although past events worldwide demonstrated that damage and death toll depends on both the strong ground motion and the ground effects. The variability of earthquake ground motion is caused by local geological conditions beneath a given site, due to the stratigraphic or topographic setting that can give rise to amplification and resonances. Earthquake-induced ground effects are mainly landslides, soil liquefaction, and ground subsidence. They can affect an area with damages related to the full collapse or loss in functionality of facilities, roads, pipelines, and other lifelines. The purpose of this session is to provide a forum for discussion among researchers and other professionals who study seismic amplification of the ground motion and the related hazards and to encourage multidisciplinary research in these fields.
Topics of interest include the following:
- Subsoil investigation and characterization for Seismic Microzonation mapping;
- Evaluation of seismic site response (1D-2D-3D)
- Case histories of earthquake-triggered landslides analyzed at either local or regional scale
- Slope stability analyses and runout modeling of seismically/volcanically-induced landslides;
- Studies on Soil liquefaction and earthquake-induced subsidence

Numerical modeling of earthquakes provides new approaches to apprehend the physics of earthquake rupture and the seismic cycle, seismic wave propagation, fault zone evolution and seismic hazard assessment.
Recent advances in numerical algorithms and increasing computational power enable unforeseen precision and multi-physics components in physics-based earthquake simulation but also pose challenges in terms of fully exploiting modern supercomputing infrastructure, realistic parameterization of simulation ingredients and the analysis of large synthetic datasets while advances in laboratory experiments link earthquake source processes to rock mechanics.
This session aims to bring together modelers and data analysts interested in the physics and computational aspects of earthquake phenomena and earthquake engineering. We welcome studies focusing on all aspects of seismic hazard assessment and the physics of earthquakes - from slow slip events, fault mechanics and rupture dynamics, to wave propagation and ground motion analysis, to the seismic cycle and inter seismic deformation - and studies which further the state-of-the art in the related computational and numerical aspects.
Earthquake swarms are characterized by a complex temporal evolution and a delayed occurrence of the largest magnitude event. In addition, seismicity often manifests with intense foreshock activity or develops in more complex sequences where doublets or triplets of large comparable magnitude earthquakes occur. The difference between earthquake swarms and these complex sequences is subtle and usually flagged as such only a posteriori. This complexity derives from aseismic transient forcing acting on top of the long-term tectonic loading: pressurization of crustal fluids, slow-slip and creeping events, and at volcanoes, magmatic processes (i.e. dike and sill intrusions or magma degassing). From an observational standpoint, these complex sequences in volcanic and tectonic regions share many similarities: seismicity rate fluctuations, earthquakes migration, and activation of large seismogenic volume despite the usual small seismic moment released. The underlying mechanisms are local increases of the pore-pressure, loading/stressing rate due to aseismic processes (creeping, slow slip events), magma-induced stress changes, earthquake-earthquake interaction via static stress transfer or a combination of those. Yet, the physics behind such processes and the ultimate reasons for the occurrence of swarm-like rather than mainshock-aftershocks sequences, is still far beyond a full understanding.
This session aims at putting together studies of swarms and complex seismic sequences driven by aseismic transients in order to enhance our insights on the physics of such processes. Contributions focusing on the characterization of these sequences in terms of spatial and temporal evolution, scaling properties, and insight on the triggering physical processes are welcome. Multidisciplinary studies using observation complementary to seismological data, such as fluid geochemistry, deformation, and geology are also welcome, as well as laboratory and numerical modeling simulating the mechanical condition yielding to swarm-like and complex seismic sequences.

Regions of slow deformation and low strain, often located in continental interiors or intraplate settings, can present substantial, under-recognised seismic hazards. The styles, rates, and spatial patterns of strain distribution and seismicity in these areas are often dissimilar to plate-boundary regions, where most of our current understanding of deformation drivers was derived. Challenges in studying slowly deforming regions include: 1) poor surface exposure and/or preservation of Quaternary-active structures, 2) long earthquake recurrence intervals, and 3) complex fault geometries, mechanics, and deformation histories, often including reactivation of inherited structures.
Interdisciplinary studies combining a diverse range of geoscientific disciplines have helped us develop a better understanding of drivers of low strain deformation. In this session, we want to explore the roles, behaviours, and associated seismic hazards of short-to-long-term active deformation and key inherited tectonic structures in these regions. We seek studies from around the globe that illuminate our understanding of these complex zones using field-based analyses, geophysics, seismology, active tectonics, geomorphology, remote sensing, numerical and analogue modelling, sedimentology, and geochronology. We particularly encourage interdisciplinary presentations, thought-provoking studies that challenge conventional wisdoms, and submissions from early career researchers.
Public information:
The last four decades of earthquake science have relied on a combination of geophysical, remote sensing, and field techniques to shed light on earthquake hazard near active plate boundaries, where the majority of earthquakes occur. However, we still lack data and explanatory models for earthquake hazard in regions located far away from plate boundary settings. These slowly deforming regions pose a significant hazard to the livelihood and security of nearby communities.
Our session seeks to bring together geoscientists from across disciplinary backgrounds to discuss challenges and recent advances in understanding earthquake processes in these regions, with an eye towards improving hazard assessment in the 21st century.
Since the beginning of the XXI Century, our society has witnessed a number of catastrophic offshore earthquakes with devastating consequences (e.g., Sumatra 2004, Japan 2010, Palu 2018 or Samos-Izmir 2020). Localizing the offshore active faults and understanding their earthquake history is key to improve modern probabilistic seismic hazard assessment (PSHA) and, thus, to be able to mitigate the consequences of future offshore events.
In the last few years, the development of new geological and geophysical instrumentation has made possible the acquisition of offshore data at various scales with unprecedented detail and resolution, as for example deep and shallow boreholes, wide-angle seismic profiles, tomography, 3D and 2D seismic reflection surveys, or ultra-high-resolution bathymetry. In addition, these instrumentation is also allowing to carry on long-term monitoring (i.e., seismology, seafloor geodesy or pore pressure) and repeat surveys (i.e., time-lapse bathymetry). These new data is leading to achieve major advances in the study of active faults in offshore areas and the characterization of their recent activity, seismogenic potential and related secondary effects (i.e., mass wasting).
The aim of this session is to compile studies that focus on the use of geological and geophysical data to identify offshore active structures, to quantify the deformation that they are producing in the seafloor, to evaluate their seismogenic and tsunamigenic potential, to characterize possibly related secondary effects such as submarine mass transport deposits, and to estimate the related hazards. Accordingly, we welcome studies and/or new perspectives and ideas in marine active tectonics, turbidite paleoseismology, offshore on-fault paleoseismology or tectonic geomorphology, and seismotectonics, from local to regional scale analysis. We also encourage the submission of studies that explore the application of new ideas to estimate coseismic seafloor deformation, to constrain earthquake timing, long-term offshore monitoring of active structures, as well as the application of fault geometrical and kinematic reconstruction to seismic and tsunami hazard analysis.

Imaging both fluid-filled fault networks and surrounding heterogeneous crust with geophysical methods is especially challenging. In these settings, fluids interact with deformation-induced seismic sources, influencing both nucleation and development of seismic sequences.
Imaging and characterizing both seismogenic structures and elastic and anelastic properties of the surrounding medium is key to understanding wider tectonic and small-scale deformation processes. Understanding the geometry and kinematics of crustal-scale faults from field observations is also critical for many green-energy applications (e.g., geothermal energy, CO2 storage, mining for minerals important for battery production). This session aims to provide an overview of techniques and applications aimed at characterizing both active and ancient seismogenic fault networks at local and regional scales.
In this session we aim to bring together passive and active-source seismologists to discuss new studies that image and characterize seismically active and ancient faults and fault networks. We welcome contributions from velocity tomography, attenuation tomography (coda, t* method, direct wave attenuation), source imaging and characterization (absolute and relative location techniques, focal mechanism and stress drop analysis, …), active-source seismic techniques (reflection, refraction, integrated drilling data, …), along with multidisciplinary studies. We particularly welcome contributions from early-career researchers and those using novel techniques (e.g., data mining and machine learning).
Transform faults are one of the three types of plate boundaries required for Earth-like plate tectonics to operate. In these locations, plates move laterally in relation to each other without significant creation or destruction of plate material. Transform plate boundaries played a fundamental role in the development of the theory of plate tectonics. The concept of transform fault was introduced by Tuzo Wilson as the final piece of a puzzle that allowed connecting ridges to convergent zones and close the circumference of lithospheric plates. Wilson recognized that transform faults were different from the already known continental transcurrent faults (or nonlithospheric strike-slip faults). The term transform plate boundary is since then been used to define a lithospheric strike-slip fault zone that constitutes a plate boundary. The term is also used more loosely to define strike-slip boundaries of diffuse tectonic blocks or microplates. At smaller orders, strike-slip faults exist in all kinds of environments and at all scales, accommodating the lateral movement of tectonic blocks and linking other kinds of faults. Transform plate boundaries can exist in both continental or oceanic lithosphere, leading to markedly different strain distribution patterns and seismic activity. This is particularly true for the case of oceanic transform faults, which result from the own growth of the plates. Due to their remote locations, the rheological structure and behavior of oceanic transform faults are still largely unknown. The fact that they exist in oceanic environments suggests that they are prone to constant fluid circulation and alteration, potentiated by the chemical reactions between rocks and circulating fluids. Transform faults have also traditionally been perceived as places of low to moderate magnitude seismicity, but recent events have shown that these structures can generate very high magnitude hazardous events. Examples include the 2010 Haiti earthquake and the 1941 M 8.4 earthquake along the Gloria Fault. In this session, we aim to discuss the evolution of oceanic and continental transform and strike-slip faults. We welcome studies on structural geology, marine geology, geochemistry, petrology, remote sensing, tectonics, seismology and hazards, as well as modelling studies, using both analogue and numerical approaches. Associated processes such as shear localization, serpentinisation, biogenic activity, fluid migration and extrusion are also very welcome.

Tsunamis can produce catastrophic damage on vulnerable coastlines, essentially following major earthquakes, landslides, extreme volcanic activity or atmospheric disturbances. After the disastrous tsunamis in 2004 and 2011, tsunami science has been continuously growing and expanding its scope to new fields of research in various domains, and also to regions where the tsunami hazard was previously underestimated.
The spectrum of topics addressed by tsunami science nowadays ranges from the “classical” themes, such as analytical and numerical modelling of different generation mechanisms (ranging from large subduction earthquakes to local earthquakes generated in tectonically complex environments, from subaerial/submarine landslides to volcanic eruptions and atmospheric disturbances), propagation and run-up, hazard-vulnerability-risk assessment, especially with probabilistic approaches able to quantify uncertainties, early warning and monitoring, to more “applied” themes such as the societal and economic impact of moderate-to-large events on coastal local and nation-wide communities, as well as the present and future challenges connected to the global climate change.
This session, co-organized with OS4, SM4, GMPV9, GM and AS, welcomes multidisciplinary as well as focused contributions covering any of the aspects mentioned above, encompassing field data, geophysical models, regional and local hazard-vulnerability-risk studies, observation databases, numerical and experimental modeling, real time networks, operational tools and procedures towards a most efficient warning, with the general scope of improving our understanding of the tsunami phenomenon, per se and in the context of the global change, and our capacity to build safer and more resilient communities.

The scope of this session includes different aspects of large-amplitude wave phenomena in the ocean such as freak or rogue waves, surface and internal waves, as well as waves trapped by currents and bathymetry. The session is focused on the understanding of the physical mechanisms which cause extreme events, the derivation of appropriate mathematical models for their description and advanced methods for their analysis. An essential part of such studies is the validation of new models and techniques versus laboratory and in-situ data. Special attention is paid to the description of wave breaking processes, and the interaction of large-amplitude waves with marine structures in offshore and coastal areas
Tsunamis and storm surges pose significant hazards to coastal communities around the world. Geological investigations, including both field studies and modelling approaches, significantly enhance our understanding of these events. Past extreme wave events may be reconstructed based on sedimentary and geomorphological evidence from low and high energy environments, from low and high latitude regions and from coastal and offshore areas. The development of novel approaches to identifying, characterising and dating evidence for these events supplements a range of established methods. Nevertheless, the differentiation between evidence for tsunamis and storms still remains a significant question for the community. Numerical and experimental modelling studies complement and enhance field observations and are crucial to improving deterministic and probabilistic approaches to hazard assessment. This session welcomes contributions on all aspects of paleo-tsunami and paleo-storm surge research, including studies that use established methods or recent interdisciplinary advances to reconstruct records of past events, or forecast the probability of future events.
Coastal areas are vulnerable to erosion, flooding and salinization driven by hydrodynamic hydro-sedimentary and biological processes and human interventions. This vulnerability is likely to be exacerbated in future with, for example, sea-level rise, changing intensity of tropical cyclones, increased subsidence due to groundwater extraction, tectonics, as well as increasing socio-economic development in the coastal zone. This calls for a better understanding of the underlying physical processes and their interaction with the coast. Numerical models therefore play a crucial role in characterizing coastal hazards and assigning risks to them. Drawing firm conclusions about current and future changes in this environment is challenging because uncertainties are often large, such as coastal impacts of likely and unlikely (also called high-end) sea-level changes for the 21st century. Furthermore, studies addressing coastal impacts beyond this century pose new questions regarding the timescale of impacts and adaptation activity. This session invites submissions focusing on assessments and case studies at global, regional and local scales of potential physical impacts of tsunamis, storm surge, sea-level rise, waves, and currents on coasts. We also welcome submissions on near-shore ocean dynamics and also on the socio-economic impact of these hazards along the coast.

We invite presentations on ocean surface waves, and wind-generated waves in particular, their dynamics, modelling and applications. This is a large topic of the physical oceanography in its own right, but it is also becoming clear that many large-scale geophysical processes are essentially coupled with the surface waves, and those include climate, weather, tropical cyclones, Marginal Ice Zone and other phenomena in the atmosphere and many issues of the upper-ocean mixing below the interface. This is a rapidly developing area of research and geophysical applications, and contributions on wave-coupled effects in the lower atmosphere and upper ocean are strongly encouraged.

Since its inception, data assimilation has proven to be enormously useful in the most varied fields throughout the Earth Sciences. It is certainly essential in meteorology, where the short-range forecasts would otherwise be almost impossible. In oceanography, its development has been slower, partly due to the smaller number of continuous and stable observations, and partly due to the fewer studies that show the importance of ocean forecasts for societal benefit. However, recently, these techniques are used more and more widely, both in operational oceanography and to produce climate reconstructions. Although the techniques are similar to those used in the atmospheric field, they have to deal with particularities due to the different environment, where the boundary conditions, open and closed, have greater importance, and the sparsity of observations poses unique challenges.
In this session, we welcome contributions describing data assimilation techniques, both methodological and case studies, in the oceanographic field. We welcome presentations of new techniques or new types of observations that cover every aspect of data assimilation, including varied applications of data assimilation, both in coastal seas and the open ocean.

Tides underlie many processes in the ocean, atmosphere and solid Earth, and influence ocean biogeochemistry and ecosystems. They drive ocean mixing, contribute to coastal erosion and sediment transport, and may provide a renewable energy source. Tides influence coastal infrastructure and safe port operations. The severity of storm surge events and coastal flooding is modulated by tides. The relationship between tides and sea ice is also important, not only for sea ice dynamics, but also for transport and mixing processes in the Arctic and Antarctic regions. Interannual variability in the tides may arise from variations in ice extent, changes in ocean stratification or regional climate processes.
Precise knowledge of tides is also necessary for earth observation where the tides are not the main target of study. They play a significant role in determining high-resolution temporal gravity fields from satellite gravimetry as well as sea-level rise estimations from satellite altimetry. Therefore, understanding the evolution of tides from both models and in-situ observations is necessary to understand the implications of tides in current and future climate estimations.
Observations and models of coastal and internal tides continue to develop, as well as their relationships to wind-driven processes and mixing processes. We welcome submissions on observations and models of surface or internal tides in the context of long-term changes in tides, tidal variability, tidal dynamics and the impacts of tides. Submissions are encouraged both from regional and global-scale studies on all aspects of tides.

Scientific drilling through the International Ocean Discovery Program (IODP) and the International Continental Scientific Drilling Program (ICDP) continues to provide unique opportunities to investigate the workings of the interior of our planet, Earth’s cycles, natural hazards and the distribution of subsurface microbial life. The past and current scientific drilling programs have brought major advances in many multidisciplinary fields of socio-economic relevance, such as climate and ecosystem evolution, palaeoceanography, the deep biosphere, deep crustal and tectonic processes, geodynamics and geohazards. This session invites contributions that present and/or review recent scientific results from deep Earth sampling and monitoring through ocean and continental drilling projects. Furthermore, we encourage contributions that outline perspectives and visions for future drilling projects, in particular projects using a multi-platform approach.

Remote sensing techniques, such as radar (e.g., synthetic aperture radar - SAR), optical, Lidar and hyperspectral imagery, together with hydroclimatic, geological, and geophysical data, as well as in-situ observations, have been widely employed for monitoring, and responding to natural and anthropogenic hazards and assessing environmental resources. Especially with the unprecedented spatio-temporal resolution and the rapid accumulation of remote sensing data collections from various spaceborne and airborne missions, we have much more opportunities to exploit hazard- and environmental- related signals, to classify the associated spatio-temporal surface changes such as deformations and landform alterations, and to interpret the primary and secondary driving mechanisms. Yet, when archiving, processing, and analyzing abundant remote sensing data, the ad hoc artificial intelligence (AI), like machine/deep learning and computer vision, is urgently required.
In this session, we welcome contributions that focus on new AI-based algorithms to retrieve remote sensing products related to environmental resources and hazards in an accurate, automated, and efficient framework. We particularly welcome contributions for applications in (1) mining, oil/gas production, fluid injection/extraction, civil infrastructure, sinkholes, land degradation, peatlands, glaciers, permafrost, and coastal subsidence; (2) emergency response based on remote sensing data to landslides, floods, winter storms, wildfires, pandemics, earthquakes, and volcanoes; and (3) mathematical and physical modeling of the remote sensing products for a better understanding on the surface and subsurface processes.

Remote sensing and Earth Observations (EO) are used increasingly in the different phases of the risk management and in development cooperation, due to the challenges posed by contemporary issues such as climate change, and increasingly complex social interactions. The advent of new, more powerful sensors and more finely tuned detection algorithms provide the opportunity to assess and quantify natural hazards, their consequences, and vulnerable regions, more comprehensively than ever before.
Several agencies have now inserted permanently into their program the applications of EO data to risk management. During the preparedness and prevention phase, EO revealed, fundamental for hazard, vulnerability, and risk mapping. EO data intervenes both in the emergency forecast and early emergency response, thanks to the potential of rapid mapping. EO data is also increasingly being used for mapping useful information for planning interventions in the recovery phase, and then providing the assessment and analysis of natural hazards, from small to large regions around the globe. In this framework, Committee on Earth Observation Satellites (CEOS) has been working from several years on disasters management related to natural hazards (e.g., volcanic, seismic, landslide and flooding ones), including pilots, demonstrators, recovery observatory concepts, Geohazard Supersites, and Natural Laboratory (GSNL) initiatives and multi-hazard management projects.
The session is dedicated to multidisciplinary contributions focused on the demonstration of the benefit of the use of EO for natural hazards and risk management.
The research presented might focus on:
- Addressed value of EO data in hazard/risk forecasting models
- Innovative applications of EO data for rapid hazard, vulnerability and risk mapping, the post-disaster recovery phase, and in support of disaster risk reduction strategies
- Development of tools for assessment and validation of hazard/risk models
The use of different types of remote sensing (e.g. thermal, visual, radar, laser, and/or the fusion of these) is highly recommended, with an evaluation of their respective pros and cons focusing also on future opportunities (e.g. new sensors, new algorithms).
Early-stage researchers are strongly encouraged to present their research. Moreover, contributions from international cooperation, such as CEOS and GEO initiatives, are welcome.

The increase of climate-related hazards has been driven by climate change, increasing human activities and infrastructure development, particularly in vulnerable areas. More efforts should be directed towards effective disaster risk management to reduce damages and losses, focusing on hazard, vulnerability, and risk mapping. Remote Sensing (RS) and Geographic Information Systems (GIS) are powerful tools in mapping change and rate of change concerning natural hazards, particularly in data-scarce environments, thanks to the great advantage of sensing extended areas at low cost and with regular revisit capability. Furthermore, satellite RS offers the opportunity to gain fresh insights into biophysical environments through satellite systems' spatial, temporal, spectral, and radiometric resolutions. The advantages of RS are further supported by the analytical and geospatial data integration capabilities of GIS.
On the other hand, proximal RS offers a unique opportunity to observe processes characterized by fast dynamics and complex geometries and provides data at ultra-high temporal and spatial resolution. The number of proximal RS solutions currently adopted to study and monitor natural hazards has progressively increased in the last decades. Nowadays, UAV, terrestrial radar interferometry, and digital photogrammetry are among the most diffuse proximal systems adopted to identify precursor elements for detailed hazard assessment and support decision-makers during emergencies. In particular, the use of these systems helps create high-resolution 3D models of the study area and monitor natural hazards. The adoption of multi-scale and multi-sensor approaches can be beneficial for studying the same phenomenon from different points of view and can support a detailed description of the studied process and the most critical parameters that can be adopted for its characterization. The availability of many technical solutions represents an additional value, but the lack of defined methodologies can limit these systems' standardized use, particularly during emergencies. This session aims to explore the use of satellite and proximal RS techniques and GIS analysis in different scenarios related to natural hazards and impact analysis and mitigation, including the preliminary characterization of potential dangerous processes, the evaluation of the elements at risk, the management of the emergency phase and the support of recovery and post-emergency reconstruction.
Synthetic aperture radar (SAR) remote sensing is an established tool for natural and anthropogenic hazards mapping and monitoring. The new generation of radar satellite constellations along with a consistent repository of historical observations is fostering comprehensive multi-sensor hazard analyses. New constellations’ capabilities rely on innovative techniques based on high-resolution/wide-swath and short-temporal Interferometric SAR (InSAR). While acknowledging the benefits brought by these recent developments, the scientific community is now defining a new paradigm of techniques capable of: extracting relevant information from SAR imagery, designing proper methodologies for specific hazards, managing large SAR datasets (e.g. National ground motion services, Copernicus EGMS), and integrating radar data with multispectral satellite observations.

The socio-economic impacts associated with floods are increasing. Floods represent the most frequent and most impacting, in terms of the number of people affected, among the weather-related disasters: nearly 0.8 billion people were affected by inundations in the last decade, while the overall economic damage is estimated to be more than $300 billion. Despite this evidence, our knowledge and accurate prediction of flood dynamics remain poor, mainly related to the lack of measurements and ancillary data at the global level.
In this context, remote sensing represents a value source of data and observations that may alleviate the decline in field surveys and gauging stations, especially in remote areas and developing countries. The implementation of remotely-sensed variables (such as digital elevation model, river width, flood extent, water level, land cover, etc.) in hydraulic modelling promises to considerably improve our process understanding and prediction. During the last decades, an increasing amount of research has been undertaken to better exploit the potential of current and future satellite observations, from both government-funded and commercial missions, as well as many datasets from airborne sensors carried on airplanes and drones. In particular, in recent years, the scientific community has shown how remotely sensed variables have the potential to play a key role in the calibration and validation of hydraulic models, as well as provide a breakthrough in real-time flood monitoring applications. With the proliferation of open data and more Earth observation data than ever before, this progress is expected to increase.
We encourage presentations related to flood monitoring and mapping through remotely sensed data including:
- Remote sensing data for flood hazard and risk mapping, including commercial satellite missions as well as airborne sensors (aircraft and drones);
- Remote sensing techniques to monitor flood dynamics;
- The use of remotely sensed data for the calibration, or validation, of hydrological or hydraulic models;
- Data assimilation of remotely sensed data into hydrological and hydraulic models;
- Improvement of river discretization and monitoring based on Earth observations;
- River flow estimation from remote sensing;
- River and flood dynamics estimation from satellite (especially time lag, flow velocity, etc.)
Remote sensing measurements, acquired using different platforms - ground, UAV, aircraft and satellite - have increasingly become rapidly developing technologies to study and monitor Earth surface, to perform comprehensive analysis and modeling, with the final goal of supporting decision systems for ecosystem management. The spectral, spatial and temporal resolutions of remote sensors have been continuously improving, making environmental remote sensing more accurate and comprehensive than ever before. Such progress enables understanding of multiscale aspects of high-risk natural phenomena and development of multi-platform and inter-disciplinary surveillance monitoring tools. The session welcomes contributions focusing on present and future perspectives in environmental remote sensing, from multispectral/hyperspectral optical and thermal sensors. Applications are encouraged to cover, but not limited to, the monitoring and characterization of environmental changes and natural hazards from volcanic and seismic processes, landslides, and soil science. Specifically, we are looking for novel solutions and approaches including the topics as follows: (i) state-of-the-art techniques focusing on novel quantitative methods; (ii) new applications for state-of-the-art sensors, including UAVs and other close-range systems; (iii) techniques for multiplatform data fusion.
The never-ending growth of the ground penetrating radar applications reserves continuously small and less small discoveries, and deserves a space for discussion and reciprocal listening also at the EGU conference.
The pandemic has meaningfully hindered many activities but to our knowledge not too much the interest in the GPR instrumentation and technique at an applicative level, even if exchanges of experiences at international conferences have been of course necessarily reduced. So, we hope that this session can meet the interest of many researchers, professionals, PhD students as well skilled GPR users as geologists, engineers, geophysicists and possibly archaeologists and architects.
Contributions are welcome with regard to all the aspects of the GPR technique, ranging from the hardware of the systems to the data processing and any theoretical aspect, including innovative applications or procedures as well as results of particular relevance, possibly achieved within an integrated measurement campaign including also different data.
Hope to see you in Vienna.
Continues monitoring of infrastructure systems are essential to ensure a reliable movement of people and goods, which involves in the economy growth and human interaction. The wide variety of instruments available allows diverse applications to increase data availability for a better understanding of geotechnical surroundings which are directly linked to the safe operation of infrastructures to prevent catastrophise such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding and even wildfires close to the highways. Understanding mentioned events are vital to provide a safe infrastructure in extreme climate conditions. This session focus on the application of geosciences and geophysical instrumentation including sensors on the infrastructures monitoring and data analysis from critical infrastructures (e.g., roadways, railway system, bridges, tunnels, water supply, underground utilities, electrical grids, and other embedded facilities in cities). The session aims to increase knowledge on geo-infrastructure management to overcome future challenges associated with the societal and human interaction, present advance knowledge research and novel approaches from various disciplines with a vibrant interaction to economy and human-interaction studies to provide an efficient infrastructure management system. The session is considered inter-and transdisciplinary (ITS) session. The applications and topics include but are not limited to: (1) Advance knowledge of the destructive and non-destructive geoscience and geophysical techniques including contactless and non-contactless techniques such as sensors. (2) Intelligent data analysis approaches to analyse accurate and precise interpretation of big data sets driven from various technologies (e.g., computer vision and image, and signal processing). (3) Influence of the surrounding areas on infrastructure management systems linked to natural events such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding, wildfires and extreme weather condition. (4) Continuous real-time monitoring to provide smart tools such as an integration of geosciences data with BIM models, Internet of Things, digital twins, robotic monitoring, artificial intelligence, automation systems based on machine learning and computational modelling for better decision-making for infrastructure owner/operators. (5) Human-interaction computer-based aided to generate reliable infrastructures.
Environmental systems often span spatial and temporal scales covering different orders of magnitude. The session is oriented toward collecting studies relevant to understand multiscale aspects of these systems and in proposing adequate multi-platform and inter-disciplinary surveillance networks monitoring tools systems. It is especially aimed to emphasize the interaction between environmental processes occurring at different scales. In particular, special attention is devoted to the studies focused on the development of new techniques and integrated instrumentation for multiscale monitoring of high natural risk areas, such as volcanic, seismic, energy exploitation, slope instability, floods, coastal instability, climate changes, and another environmental context.
We expect contributions derived from several disciplines, such as applied geophysics, geology, seismology, geodesy, geochemistry, remote and proximal sensing, volcanology, geotechnical, soil science, marine geology, oceanography, climatology, and meteorology. In this context, the contributions in analytical and numerical modeling of geological and environmental processes are also expected.
Finally, we stress that the inter-disciplinary studies that highlight the multiscale properties of natural processes analyzed and monitored by using several methodologies are welcome.

Geomorphometry and landform mapping are important tools used for understanding landscape processes and dynamics on Earth and other planetary bodies. The recent rapid advances in technology and data collection methods have made available vast quantities of geospatial data offering unprecedented spatio-temporal range, density, and resolution, but it also created new challenges in terms of data processing and analysis.
This inter-disciplinary session on geomorphometry and landform mapping aims to bridge the gap between process-focused research fields and the technical domain where geospatial products and analytical methods are developed. The increasing availability of a wide range of geospatial datasets requires the continued development of new tools and analytical approaches as well as landform/landscape classifications. However, a potential lack of communication across disciplines results in efforts to be mainly focused on problems within individual fields. We aim to foster collaboration and the sharing of ideas across subject-boundaries, between technique developers and users, enabling us as a community to fully exploit the wealth of geospatial data that is now available.
We welcome perspectives on geomorphometry and landform mapping from ANY discipline (e.g. geomorphology, planetary science, natural hazard assessment, computer science, remote sensing). This session aims to showcase both technical and applied studies, and we welcome contributions that present (a) new techniques for collecting or deriving geospatial data products, (b) novel tools for analysing geospatial data and extracting innovative geomorphometric variables, (c) mapping and/or morphometric analysis of specific landforms as well as whole landscapes, and (d) mapping and/or morphometric analysis of newly available geospatial datasets. Contributions that demonstrate multi-method or inter-disciplinary approaches are particularly encouraged. We also actively encourage contributors to present tools/methods that are “in development”.

We aim herein to focus and illustrate all UAS/drone classical and new techniques and processing in order to study all Geological & Geomorphological objects in terms of 3D geometry (description and localisation, characterisation, quantification, modelisation...) in order to better constrained Earth Sciences processes.
Consequently, dealing with the technical point of view, it takes into account not only classical photogrammetric data processing through aerial photographs but also new techniques such as UAS-Lidar acquisition, and/or new UAS-interferometric acquisitions.
Many resulting dataset should be provided and discussed as key examples such as Very High Resolution Digital Terrain Model and/or Digital Surface Model (VHR DTM/DSM) less than 10cm ground resolution pixels that lead to acquire much more precise geometries, to up-date geological and geomorphological mapping and up-date structural scheme of geological targets. Many case examples could be listed herein such as analogs of sandstones or limestones reservoirs, active sedimentological processes in shoreline areas, or Natural Hazards processes such as landslides, etc...
For instance, in the active tectonic areas the HR UAS DTM may be combined with classical geodetic measurements such as levelings, numerous GPS and RTK surveys... and/or spatial PSInSAR, Smallbase line interferometric analyses in order to decipher and precise the active faults and folds structures and evenmore participate to determine the seismic cycles of major active faults.
We aim in this session to share our UAS/drone experiences on the various geological and geomorphological objects outcropping wherever the place of the Earth.
Geomorphometry, a science of quantitative land surface analysis, gathers various mathematical, statistical and image processing techniques to quantify morphological, hydrological, ecological and other aspects of a land surface. The typical input to geomorphometric analysis is a square-grid representation of the land surface: a digital elevation model (DEM) or one of its derivatives. DEMs provide the backbone for many studies in Geo sciences, hydrology, land use planning and management, Earth observation and natural hazards.
One topic of active research concerns compromises between the use of global DEMs at 1-3 arc second, ~30-90 m grid spacing, and local LiDAR/structure from motion (SFM) elevation models at 1 m or finer grid spacing. Point clouds from LiDAR, either ground-based or from airborne vehicles, are a generally accepted reference tool to assess the accuracy of other DEMs. SFM data have a resolution comparable to LiDAR point clouds, but can cost significantly less to acquire for smaller areas. Globally available DEMS include the recently published Copernicus GLO-90 and GLO-30. This session provides an exciting forum to show the potential applications of this new DEM and its improvements over SRTM. We would like to investigate the tradeoff between the employment of the two kinds of data, and applications which can benefit from data at both (local and global) scales.
The improvements in the global DEMs, as well as the increasing availability of much finer resolution LiDAR and SFM DEMs, call for new analytical methods and advanced geo-computation techniques, necessary to cope with diverse application contexts. We aim at investigating new methods of analysis and advanced geo-computation techniques, including high-performance and parallel computing implementations of specific approaches.
Commercial applications of DEM data and of geomorphometric techniques can benefit important business sectors. Besides a proliferation of applications that can tolerate low accuracy geographical data and simple GIS applications, a large base of professionals use high-resolution, high-accuracy elevation data and high-performance GIS processing. We would like to survey and investigate professional, commercial and industrial applications, including software packages, from small enterprises to large companies, to ascertain how academic researchers and industry can work together.
Recent advances in image collection, e.g. using unoccupied aerial vehicles (UAVs), and topographic measurements, e.g. using terrestrial or airborne LiDAR, are providing an unprecedented insight into landscape and process characterization in geosciences. In parallel, historical data including terrestrial, aerial, and satellite photos as well as historical digital elevation models (DEMs), can extend high-resolution time series and offer exciting potential to distinguish anthropogenic from natural causes of environmental change and to reconstruct the long-term evolution of the surface from local to regional scale.
For both historic and contemporary scenarios, the rise of techniques with ‘structure from motion’ (SfM) processing has democratized data processing and offers a new measurement paradigm to geoscientists. Photogrammetric and remote sensing data are now available on spatial scales from millimetres to kilometres and over durations of single events to lasting time series (e.g. from sub-second to decadal-duration time-lapse), allowing the evaluation of event magnitude and frequency interrelationships.
The session welcomes contributions from a broad range of geoscience disciplines such as geomorphology, cryosphere, volcanology, hydrology, bio-geosciences, and geology, addressing methodological and applied studies. Our goal is to create a diversified and interdisciplinary session to explore the potential, limitations, and challenges of topographic and orthoimage datasets for the reconstruction and interpretation of past and present 2D and 3D changes in different environments and processes. We further encourage contributions describing workflows that optimize data acquisition and processing to guarantee acceptable accuracies and to automate data application (e.g. geomorphic feature detection and tracking), and field-based experimental studies using novel multi-instrument and multi-scale methodologies. This session invites contributions on the state of the art and the latest developments in i) modern photogrammetric and topographic measurements, ii) remote sensing techniques as well as applications, iii) time-series processing and analysis, and iv) modelling and data processing tools, for instance, using machine learning approaches.
Wildfires represent a hazardous and harmful phenomenon to people and the environment, especially in populated areas where the primary cause of ignition is related to human activities. This has motivated governments to develop spatio-temporal datasets and to produce risk and prognostic maps. A key tool in this respect is to investigate the spatial and temporal distribution of wildfires and to understand its relationships with the surrounding environmental, climatological and socio-economic factors.
Innovative algorithms and methodologies have been developed in recent years to analyze spatially distributed natural hazards and ongoing phenomena such as wildfires. Considering the fast growing availability of high quality digital geo-referenced databases, it is important to promote methods and new tools for their study, especially for large-scale analysis. A new exciting challenge is to convert available datasets into meaningful and valuable information.
This session will bring together wildfire hazard scientists and researchers of various geo-environmental disciplines, economists, managers and people responsible for territorial and urban defense and planning policies. The main goal is to improve the understanding of the fire regime and to discuss new strategies to mitigate the disastrous effects of wildfires. We will examine empirical studies, new and innovative technologies, theories, models and strategies for wildfire research, seeking especially to identify and characterize spatial and temporal variability patterns of wildfires.
Research topics include, but are not limited, to the following:
• development of methodologies based on expert knowledge or data driven approaches, for the recognition, modelling and prediction of structured patterns in wildfires;
• pre- and post-fire assessment: fire incidence mapping and variability, fire severity and damage, including fire-planning and risk management;
• long-term trend patterns: relation between wildfires and global changes such as climate and land use/land cover changes;
• fire impacts on the environment, in particular on the atmosphere, human health and natural/anthropogenic environment;
• fire spread models, ranging from case studies to long-term climatological assessments;
• post-fire vegetation recovery and vegetation phenology.
Public information:
This year our session will cover research topics that includes:

Fire is an essential feature of terrestrial ecosystems and an important component of the Earth system. Climate, vegetation, and human activity regulate fire occurrence and spread, but fires also feedback to them in multiple ways. This session welcomes contributions that explore the role of fire in the Earth system at any temporal and spatial scale using modeling, field and laboratory observations, proxy-records, and/or remote sensing. We encourage all abstracts that advance our understanding on interactions between fire and (1) weather, climate, as well as atmospheric chemistry and circulation, (2) biogeochemical, energy, and water cycles, (3) vegetation composition and structure, (4) pyrogenic carbon, including effects on soil functioning and soil organic matter dynamics, (5) cryosphere (e.g. permafrost, sea ice), and (6) humans (e.g., impact of fire on air and water quality, freshwater resources, human health, land use and land cover change, fire management). We also welcome contributions focusing on fire characterization, including (7) fire behavior and emissions (e.g. fire duration, emission factors, emission height, smoke transport), (8) spatial and temporal changes of fire regimes in the past, present, and future, (9) fire products and models, and their validation, error/bias assessment and correction, and (10) analytical tools designed to enhance situational awareness among fire practitioners and early warning systems.

Wildfires are a worldwide phenomenon with many environmental, social, and economic implications, which are expected to escalate as a consequence of climate change and land abandonment, management, and planning, further promoting land degradation and decreasing ecosystem services supply.
The current situation demands from the scientific community the study of wildfire effects on the ecosystems and the development of integrated tools for pre- and post-fire land management practices that reduce the vulnerability to wildfires and their impacts. However, this research urges the attention not only from researchers, but also from stakeholders and policy-makers all over the world, since basic resources such as raw materials, water, and soils as well as habitats are at stake.
This session aims at gathering researchers on the effects of wildfires on ecosystems, from wildfire prevention to post-fire mitigation. We kindly invite laboratory, field, and/or modelling studies involving the following topics:
i. prescribed and/or experimental fires;
ii. fire severity and burn severity;
iii. fire effects on vegetation, soil and water;
iv. post-fire hydrological and erosive response;
v. post-fire management and mitigation;
vi. socio-economic studies on pre- and post-fire land management;
vii. fire risk assessment and modelling.

Perhaps the most dramatic demonstration of the impact of global environmental change has been the rapid change in fire regimes, from the Amazon to suburban Athens. However, the observed disruption in global wildfire regimes has not yet been directly attributed to climate – but only to weather patterns that make wildfires more likely.
At the heart of this issue is a lack of understanding of the diverse socio-ecological feedbacks that are driving Anthropocene wildfires. For example, in response to damaging fire events, common policy responses such as increased suppression and fire use bans may ultimately exacerbate fire risk by leading to large build-ups of flammable and connected fuels. Meanwhile a combination of global-scale trade conflict, national-scale political change and regional drought have all contributed to a surge in wildfires in the Amazon basin. These examples highlight the urgent need for new transdisciplinary approaches to wildfire research that account for feedbacks between land use and wider environmental change.
In this session we welcome a broad range of contributions that explore the interactions between socio-economic and biophysical drivers of wildfires, encompassing disciplines including: anthropology, earth observation, ecology, economics, land surface and climate modelling, and political science. Example topics might include how agricultural intensification, land degradation and CO2 fertilisation effects combine to alter fire regimes in grassland ecosystems, through to how rural and urban populations’ contrasting perceptions of risk can influence land management policies.
We particularly encourage contributions that demonstrate how methods from different disciplines may inform each other. Holistic advances in our understanding can lead to better adaptation policies and strategies, and will be vital to improved wildfire modelling and attribution of fire regime changes to climate change.

Exposure to mineral dust is an important, global cause of respiratory diseases, mainly in occupational settings. Though the incidence of occupational lung disease has decreased in many countries, exposure to silica, asbestos, and other mineral dusts are responsible for 25% of all occupational lung diseases (WHO study, 2017). Re-emergence of lung diseases associated with unexpected sources, and non-conventional exposure scenarios require an up-to-date risk assessment, monitoring, and mitigation strategies. A new frontier of the research in mineral dust is to design an integrated occupational and environmental strategy (exposome) for health hazard control and for increased awareness of social and environmental impact.
To tackle these challenges, this session welcomes contributions and case studies on the following aspects:
- particle and fibre mineralogical definition, including regulatory aspects;
- particle and fibre risk assessment, migration, transport, and fate in natural environments including air, water, and soil/rock, and in occupational settings;
- physico-chemical assessment of particle and fibre characteristics relevant to interactions with biological milieu, and mechanisms of toxicity;
- development of novel approaches for the determination of inorganic particle and fibre occurrences, risk management, air sampling procedures for outdoor/indoor environments, protection strategies for workers, environment, and population at large;
- all other studies on environmental, occupational, and non-conventional exposures to inorganic dust, including asbestos, silica, silicates, volcanic ashes, celestial dusts, dusts from construction sites, and more in general composite dust.
This session’s contributions aim to invite an interdisciplinary audience, encompassing mineralogy, geology, environmental chemistry, epidemiology, and medicine.
The virus is still with us, with more potent variants. It remains the most immediate challenge for geosciences and health, including its impacts on geoscience development (data collection, training, dissemination) and the achievement of the UN Sustainable Development Goals, in particular that urban systems should increase well-being and health.
Long-term visions based on transdisciplinary scientific advances are therefore essential. As a consequence, this session, like the ITS1.1 session in 2021, calls for contributions based on data-driven and theory-based approaches to health in the context of global change. This includes :
- main lessons from lockdowns?
- how to get the best scientific results during a corona pandemic?
- how to manage field works, geophysical monitoring and planetary missions?
- qualitative improvements in epidemic modelling, with nonlinear, stochastic, and complex system science approaches;
- eventual interactions between weather and/or climate factors and epidemic/health problems
- new surveillance capabilities (including contact tracing), data access, assimilation and multidimensional analysis techniques;
- a fundamental revision of our urban systems, their greening and their need for mobility;
- a special focus on urban biodiversity, especially to better manage virus vectors;
- urban resilience must include resilience to epidemics, and therefore requires revisions of urban governance.

The session gathers geoscientific aspects such as dynamics, reactions, and environmental/health consequences of radioactive materials that are massively released accidentally (e.g., Chernobyl and Fukushima nuclear power plant accidents, wide fires, etc.) and by other human activities (e.g., nuclear tests).
The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Thus, the radioactive contamination problem is multi-disciplinary. In fact, this topic involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic and ecosystem, and its relations with human and non-human biota. The topic also involves hazard prediction and nowcast technology.
By combining 35 years (> halftime of Cesium 137) monitoring data after the Chernobyl Accident in 1986, 10 years dense measurement data by the most advanced instrumentation after the Fukushima Accident in 2011, and other events, we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents.
The following specific topics have traditionally been discussed:
(a) Atmospheric Science (emissions, transport, deposition, pollution);
(b) Hydrology (transport in surface and ground water system, soil-water interactions);
(c) Oceanology (transport, bio-system interaction);
(d) Soil System (transport, chemical interaction, transfer to organic system);
(e) Forestry;
(f) Natural Hazards (warning systems, health risk assessments, geophysical variability);
(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).
The session consists of updated observations, new theoretical developments including simulations, and improved methods or tools which could improve observation and prediction capabilities during eventual future nuclear emergencies. New evaluations of existing tools, past nuclear contamination events and other data sets also welcome.

Natural radioactivity is ubiquitous in the environment as a result of i) cosmic radiation from space and secondary radiation from the interaction of cosmic rays with the atmosphere, ii) terrestrial sources from soils and rocks and particularly Potassium, Uranium and Thorium and their decay products among which Radon gas stands out. Artificial radionuclides from nuclear and radiation accidents and incidents makes up an additional contribution to the environmental radioactivity.
Nuclear techniques enable the measurement of radioactivity in air, soils and water even at trace levels, making it a particularly appealing tool for tracing time-varying environmental phenomena. This session welcomes contributions addressing the measurement and exploitation of environmental radioactivity in all areas of geosciences, including, but not limited to:
- geological and geomorphological surveys;
- mineral exploration;
- groundwater contamination;
- coastal and marine monitoring;
- soil erosion processes;
- Naturally Occurring Radioactive Materials (NORMs);
- geostatistical methods for radioactivity mapping;
- airborne and drones surveys;
- novel methods and instrumentations;
- atmospheric tracing, mixing and transport processes;
- public health including the EU BSS directive and Euratom-Drinking Water Directive

Hydroclimatic conditions and availability of water resources in space and time constitute important factors for maintaining adequate food supply, the quality of the environment, and the welfare of citizens and inhabitants, in the context of a post-pandemic sustainable growth and economic development. This session is designed to explore the impacts of hydroclimatic variability, climate change, and temporal and spatial availability of water resources on different factors, such as food production, population health, environment quality, and local ecosystem welfare.
We particularly welcome submissions on the following topics:
• Complex inter-linkages between hydroclimatic conditions, food production, and population health, including: extreme weather events, surface and subsurface water resources, surface temperatures, and their impacts on food security, livelihoods, and water- and food-borne illnesses in urban and rural environments.
• Quantitative assessment of surface-water and groundwater resources, and their contribution to agricultural system and ecosystem statuses.
• Spatiotemporal modeling of the availability of water resources, flooding, droughts, and climate change, in the context of water quality and usage for food production, agricultural irrigation, and health impacts over a wide range of spatiotemporal scales.
• Smart infrastructure for water usage, reduction of water losses, irrigation, environmental and ecological health monitoring, such as development of advanced sensors, remote sensing, data collection, and associated modeling approaches.
• Modelling tools for organizing integrated solutions for water supply, precision agriculture, ecosystem health monitoring, and characterization of environmental conditions.
• Water re-allocation and treatment for agricultural, environmental, and health related purposes.
• Impact assessment of water-related natural disasters, and anthropogenic forcing (e.g. inappropriate agricultural practices, and land usage) on the natural environment (e.g. health impacts from water and air, fragmentation of habitats, etc.)

The demand for raw materials and critical raw materials, to supply the needs of both society and industry, is continuously growing, imposing environmental, societal, and technological challenges.
These activities are inevitably accompanied by the production of large volumes of residues, through both exploitation and processing.
In the past, mining activity and extractive waste management were approached, mainly considering the environmental hazards and landscape degradation, but, nowadays, the development of innovative and technological processes, that allow us to reduce, reuse and recycle such industrial residues, as well as more sustainable exploitation practices, give us the opportunities to exploit the huge volumes of past mineral waste as an important source of raw materials.
Residues, such as waste rock, tailings, slags and fly ashes, often hold impressive residual mineral values, and have the potential to be converted to secondary raw materials and mineral resources, for these reasons further challenges are the geochemical, petrographic and mineralogical characterization and the modelization of waste deposits to realistically assess the prospects for sustainable exploitation. It must become the norm to maximize resource use, reduce the volume for final disposal, and also mitigate the risk of environmental damage, associated with the increasing global demand for raw materials and minerals resources.
The main topics to be discussed in this session address, but are not limited to:
- Characterization of geomaterials, their environmental interactions, and decay
- Characterization of industrial residue resources and their environmental assessment
- Secondary raw materials exploitation and valorisation

The purpose of this session is to: (1) showcase the current state-of-the-art in global and continental scale natural hazard risk science, assessment, and application; (2) foster broader exchange of knowledge, datasets, methods, models, and good practice between scientists and practitioners working on different natural hazards and across disciplines globally; and (3) collaboratively identify future research avenues.
Reducing natural hazard risk is high on the global political agenda. For example, it is at the heart of the Sendai Framework for Disaster Risk Reduction and the Paris Agreement. In response, the last decade has seen an explosion in the number of scientific datasets, methods, and models for assessing risk at the global and continental scale. More and more, these datasets, methods and models are being applied together with stakeholders in the decision decision-making process.
We invite contributions related to all aspects of natural hazard risk assessment at the continental to global scale, including contributions focusing on single hazards, multiple hazards, or a combination or cascade of hazards. We also encourage contributions examining the use of scientific methods in practice, and the appropriate use of continental to global risk assessment data in efforts to reduce risks. Furthermore, we encourage contributions focusing on globally applicable methods, such as novel methods for using globally available datasets and models to force more local models or inform more local risk assessment.

Increasing effects of climate change, urbanization, and increased interconnectedness between ecological, physical, human, and technological systems pose major challenges to disaster risk management in a globalised world. Economic losses from natural hazards and climate change are still increasing, and the recent series of catastrophic events across the world together with the COVID-19 crisis has manifested the urgent need to shift from single-hazard-based approaches to new and innovative ways of assessing and managing risk based on a multi-hazard and systemic risk lens. This calls for novel scientific approaches and new types of data collections to integrate the study of multiple natural processes and human influences triggering hazards, including studies of ecological, physical, socioeconomic, political, and technical factors that shape exposure and vulnerability of humans, sectors and systems across borders and scales.
Tackling the above challenges, this session aims to gather the latest research, empirical studies, and observation data that are useful for understanding and assessing the interplay between multiple natural hazards and social vulnerability to: (i) identify persistent gaps, (ii) propose potential ways forward, and (iii) inform resilience building strategies in the context of global change.

Disasters caused by natural hazards often lead to significant and long-lasting disruptions of economic, social and ecological systems. To improve both ex-ante disaster risk reduction and ex-post recovery, increasing attention is placed on strengthening the “disaster resilience” of communities, cities, regions and countries. However, a lack of empirical data and evidence, a high diversity in assessment and measurement approaches as well as various definitions of disaster resilience make it difficult to establish a solid understanding of what contributes to disaster resilience and how it can be measured. This hinders targeted resilience strengthening investments and actions across all levels, that are increasingly demanded in the context of climate change adaptation and sustainable development.
This session aims to discuss concepts and frameworks that improve the understanding of economic, social and ecological resilience to various natural hazards (e.g. floods, droughts, wildfires) including compound events as well as to review current frameworks and tools that aim to measure disaster resilience. We invite submissions addressing process- and outcome-based approaches to assess or measure disaster resilience, as well as studies using remote sensing, climate information or other innovative approaches such as predictive models aiming to quantify disaster resilience. We especially welcome presentations looking at cross-learnings and links between natural hazard resilience and public health as a result of the ongoing Covid-19 pandemic. Studies could include operationalized and applied resilience assessment frameworks, case studies using new data sets to measure resilience as well new tools and approaches to engage with decision makers, practitioners and the general public. We also welcome submissions from governments at all levels, the development and humanitarian sector as well as practitioners that effectively work for the hazard affected communities both from the developed and developing world.

Assessing the costs of the overall economic impacts of natural hazards, costs of prevention and costs of responses to natural hazards supply crucial information for decision-making practices in the fields of disaster risk reduction, natural hazard and risk management and climate change adaptation planning. However, the lack of empirical impact data as well as the significant diversity in methods that are currently applied in costs assessments of different natural hazards and impacted sectors make it difficult to establish comprehensive, robust and reliable cost figures. This also hinders comparisons of associated costs across countries, hazards and impacted sectors. This session aims to review current methodological approaches for assessing individual cost types (such as direct damages to housing, indirect losses, as well as costs of risk reduction) and aims to show how these methods are used in the context of various natural hazards (e.g. floods, droughts, earthquakes).
We welcome submissions in the areas of assessing these various types of damage induced by any kind of natural hazard. Also, we are interested in contributions that focus on the cost-effectiveness or efficiency of risk reduction to natural hazards and adaptation to increasing weather risks that are due to climate change. Presentations are welcome for instance on model development, validation, uncertainty analysis, risk assessment frameworks as well as presentations about the application of damage models in case studies. Abstracts are sought from those involved in both the theoretical and practical aspects related to these topics.
Excellent submissions which are deemed important contributions to the session will be classified as “solicited talks”.
Critical infrastructures and other technological systems such as transportation systems, telecommunication networks, power lines, pipelines, and reservoirs are at risk of natural hazards (e.g., earthquakes, floods, landslides, wildfires) in many urban and rural areas worldwide. A key to safe and affordable operations of these types of infrastructure is an in-depth knowledge of their exposure and vulnerability to natural hazards and the impact of damage experienced either locally or across the network. Fundamental understanding of hazard and risk involves (a) systematic identification, monitoring, and mapping of potential infrastructure exposure; (b) integrated assessment of impact as result of damage, repair and/or mitigation; (c) indirect losses from infrastructure disruption and synergistic effects; (d) consideration of interactions between hazards and/or cascades of hazards. This session welcomes contributions with a focus on natural hazards risk assessment for critical infrastructures and technological systems, and compilation of databases to record impact and elements at risk. We also encourage abstracts addressing the development and application of tools for cost modeling. The session is dedicated to contributions with national, regional, and local perspective and intends to bring together experts from science and practice as well as young scientists. We encourage submissions for interactive presentations, which can be presented online in virtual discussion.

The adverse effects of droughts are felt all over the globe, especially in recent years. Droughts often lead to direct and indirect impacts on different sectors from local to global scales. The likelihood of such impacts, understood as drought risk, is caused by the combination of drought hazards, exposure and systems’ vulnerabilities. To support the identification and planning of drought risk reduction and adaptation options, information is needed on the root causes, patterns and dynamics of drought risk and its related impacts. Even though the effects of drought are widespread and well known, research focusing on the different drought risk dimensions lags behind other natural hazard research. Common standards for risk analysis and its components, as well as for impact assessment, are missing. Furthermore, there are no common criteria for assessing the impacts of past and potential future droughts. Whether this is due to the difficulty to grasp the hazard, the lack of standards for vulnerability, exposure and risk assessment, the myriad of different sectors involved, or the complex web of direct and indirect impacts remains unknown so far.
This session addresses drought research beyond the hazard. This includes techniques to collect drought impact information, methods to assess exposure, vulnerability and drought risk for different sectors (e.g. agriculture, forestry, energy production, public water supply, commercial shipping, tourism, wildfires, human health), at different spatial (local to global) and temporal (past trends, current patterns, future scenarios) scales. The session aims to gather examples from around the globe at different scales, discussing best practices, existing challenges and potential ways forward. We welcome the full variety of thematic foci (hazard, exposure, vulnerability, risk, and impact assessment) based on qualitative, quantitative and mixed-methods approaches. The session aims to bring together scientists and practitioners to evaluate the current state-of-the-art, foster drought risk research, establish a community of researchers and practitioners, and shape the future of drought vulnerability and risk research.
The session is closely linked to the NHESS special issue “Drought vulnerability, risk, and impact assessments: bridging the science-policy gap” https://nhess.copernicus.org/articles/special_issue1113.html of which we strongly encourage all session contributors to be part.
Hydrometeorological and geomorphological hazards account for 45% of the fatalities and 79% of global economic losses. Exacerbated by high seismic activity and rugged terrain, the Himalayan landscape is particularly susceptible to generating these events, which often transform into cascading hazards—an initial event causes a downstream hazard chain, e.g. glacial lake outburst floods to debris flows. These hazards interfere with increasing population pressure and expansion of settlements along rivers and new infrastructure developments such as roads and hydropower projects. Rising temperatures and changes in weather patterns in the wake of global warming likely elevate risks from hazards such as landslides, glacial lake outburst floods, riverine and flash floods. The complexity of these hazards and their underlying processes demand scientific efforts and approaches from multiple disciplines.
Multidisciplinary approaches and methodologies are important to holistically estimate and predict hazard events and interactions of multiple hazards, and to understand how vulnerable societies cope and respond to these hazards in the Himalayan region.
This session aims to bring together expertise on approaches, methods, and data to advance the understanding of the impacts and changes in the extremely high mountain landscapes, with a particular focus on the trends of hydro-geomorphological disasters on the Himalayas and their societal impacts.
We welcome contributions from research topics (but not restricted to):
-hydro-geophysical modeling (landslides, glacial lake outburst floods, riverine and flash floods)
-extreme event modeling
-remote-sensing-based observations
-risk/vulnerability assessment
-theories and models of reducing vulnerabilities and adaptation to natural hazards
-innovative data approaches to integrate natural and social science perspective
-recovery to natural hazards, in particular, usage of longitudinal data methods
The session is closely linked to the NHESS special issue “Estimating and Predicting Natural Hazards and Vulnerabilities in the Himalayan Region”. We encourage all session contributors to support this issue.

UN projects urban agglomeration to increase to 68% by 2050 from 55%. The majority of this positive trend is projected to happen in developing countries like those in the tropics (24S—24N). Especially in urban centres, the increasing population is motivated to consider alternative locations to settle. Hence, urban areas at the coast and mountainous terrains expand towards hillslopes and flood plains, increasing the exposure to natural hazards, especially landslides and floods. Heat extremes are increasing in frequency and severity in a warming climate, and the transformation of the land surface in urban centres (heat-absorbing materials, such as asphalt, steel, and brick) causes temperatures to rise further. Understanding the chance of heat extremes and their impacts is vital to allow society to adapt to future risks. Rapid agglomeration also fosters informal housing in those peri-urban areas. Those informal structures are not only structurally more vulnerable, but they also partly increase the impact of some natural hazards by, for instance, poorly regulated water management systems. The session is dedicated to contributions with national, regional, and local perspectives on urban interaction with natural hazards. The session aims to bring together experts from both science and practice to offer a platform to raise awareness and explore solutions. We seek to discuss the following topics, among others, during the session:
- Expected changes in exposure and vulnerability to natural hazards due to urbanization
- Whether informal housing alter natural hazard susceptibility
- Impacts of natural hazards as a result of increasing concentration of population in specific regions
- The role of climate change on natural hazards in urban spaces
- Impacts of heat extremes on human health and society

The current scientific consensus links climate change to devastating consequences for society including natural hazards, heatwaves, floods, droughts and hurricanes. Yet, potential solutions requiring collaboration between communities, local actors and scientists continue to face considerable structural, spatial, temporal and definitional challenges.
Structural challenges: Political and micro-political aspects and how they interact with structural inequalities are important to understand vulnerability and the disproportionate impacts of climate change induced extreme events.
Spatial challenges: At the local level, providing usable information for people is challenging particularly in the poorest regions of the world. While hazards can be explored with weather and climate data. overall risk can only be assessed by balancing location-specific information and data which is often inaccessible or under researched.
Temporal challenge: Often climate change impacts have not been monitored consistently or according to the best available science and data. Particularly in the global South and developing economies, these temporal challenges make effective adaptation challenging.
Definitional challenge: vulnerability across time-space is defined in diverse ways. Many approaches tend to use hazard, exposure and vulnerability interchangeably. Whereas the assessment of local vulnerability is only possible by combining natural and social sciences with stakeholder engagement, prevailing interventions miss one or the other resulting in limited possibility for project sustainability Furthermore, a universal conceptualization or approach to vulnerability is yet to be presented.
Local adaptation solutions to these challenges do exist and could be used as models to be transferred to other regions. For example, UNESCO-designated sites such as Biosphere Reserves and UNESCO Global Geoparks provide solutions for climate change mitigation and adaptation based on inclusive, transparent, and empowering governance processes, in line with sustainable development.
We welcome research on locally produced and scientifically robust solutions to these structural, spatial, temporal and definitional challenges. Particularly abstracts focusing on 1) the quantification of hazards, risks, and impacts that matter for the identified community, 2) conceptual frameworks and tools to assess vulnerability and exposure, 3) approaches to monitor impacts and 4) case studies that showcase local solutions.

Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

This session aims to share innovative approaches to developing multi-hazard risk assessments and their components (hazard, exposure, vulnerability and capacity), and to explore their applications to disaster risk reduction.
Effective disaster risk reduction practices and the planning of resilient communities requires the evaluation of multiple hazards and their interactions. This approach is endorsed by the UN Sendai Framework for Disaster Risk Reduction. Multi-hazard risk and multi-hazard impact assessments look at interaction mechanisms among different natural hazards, and how spatial and temporal overlap of hazards influences the exposure and vulnerability of elements at risk. Moreover, the uncertainty associated with multi-hazard risk scenarios needs to be considered, particularly in the context of climate change and slow-onset hazards, such as Covid-19 and pandemics in general, characterized by dynamic changes in exposure and vulnerability that are challenging to quantify.
This session, therefore, aims to profile a diverse range of multi-hazard risk and impact approaches, including hazard interactions, multi-vulnerability studies, and multi-hazard exposure characterization. In covering the whole risk assessment chain, we propose that it will be easier to identify potential research gaps, synergies and opportunities for future collaborations.
We encourage abstracts which present innovative research, case study examples and commentary throughout the whole disaster risk cycle on (i) multi-hazard risk methodologies which address multi-vulnerability and multi-impact aspects; (ii) methodologies and tools for multi-hazard risk management and inclusive risk-informed decision making and planning; (iii) methodologies and tools for multi-hazard disaster scenario definition and management for (near) real-time applications; (iv) cross-sectoral approaches to multi-hazard risk, incorporating the physical, social, economic, and/or environmental dimensions; (v) uncertainty in multi-hazard risk and multi-hazard impact assessment; (vi) evaluation of multi-hazard risk under future climate and slow-onset hazards, including pandemics; (vii) implementation of disaster risk reduction measures within a multi-hazard perspective.

High-impact climate and weather events typically result from the interaction of multiple hazards across various spatial and temporal scales. These events, also known as Compound Events, often cause more severe socio-economic impacts than single-hazard events, rendering traditional univariate extreme event analyses and risk assessment techniques insufficient. It is therefore crucial to develop new methodologies that account for the possible interaction of multiple physical drivers when analysing high-impact events. Such an endeavour requires (i) a deeper understanding of the interplay of mechanisms causing Compound Events and (ii) an evaluation of the performance of climate/weather, statistical and impact models in representing Compound Events.
The European COST Action DAMOCLES coordinates these efforts by building a research network consisting of climate scientists, impact modellers, statisticians, and stakeholders. This session creates a platform for this network and acts as an introduction of the work related to DAMOCLES to the research community.
We invite papers studying all aspects of Compound Events, which might relate to (but are not limited to) the following topics:
Synthesis and Analysis: What are common features for different classes of Compound Events? Which climate variables need to be assessed jointly in order to address related impacts? How much is currently known about the dependence between these variables?
Stakeholders and science-user interface: Which events are most relevant for stakeholders? What are novel approaches to ensure continuous stakeholder engagement?
Impacts: What are the currently available sources of impact data? How can they be used to link observed impacts to climate and weather events?
Statistical approaches, model development and evaluation: What are possible novel statistical models that could be applied in the assessment of Compound Events?
Realistic model simulations of events: What are the physical mechanisms behind different types of Compound Events? What type of interactions result in the joint impact of the hazards that are involved in the event? How do these interactions influence risk assessment analyses?

This session aims to share the latest developments in critical infrastructure risk modelling with a focus on multi-hazard, multi-risk, cascading events, and compound risks.
Critical infrastructure, such as the energy, water and waste systems, transportation networks, telecommunication systems, education, and health infrastructures - play an essential role in societies’ day-to-day functioning. At the same time, occurrences of natural hazards highlight the importance of improving our understanding on how these infrastructures respond under stress: a disruption of a single critical infrastructure service can quickly result in a cascading effect to households, companies, or other infrastructure systems, thereby causing wide-spread impacts to the economy and society.
Compound events and connected extremes put pressure on infrastructure systems beyond their design specifications, making it crucial to understand and incorporate such effects into infrastructure planning and risk assessments. In this session, we therefore encourage abstracts aimed at:
1) Improving our understanding of exposure and vulnerability of critical infrastructure systems to (multiple) natural hazards.
2) Collecting and analyzing empirical data of past events/disruptions to inform, validate and improve risk modelling.
3) Impact (modelling) that is sensitive to the specificities of different hazards / sub-hazards / concurring multi-hazards (e.g. TC sub-hazards- flash floods bring very different impacts than strong winds, occur at different geographies, etc.).
4) Impact modelling that captures network character and interdependencies of critical infrastructures, and modelling that doesn’t end at infrastructure asset damages: e.g. differentiated social impacts, business & supply chain disruptions.
5) Dealing with the inherent uncertainty within infrastructure risk modelling and the applicability of these risk models for decision making and adaptation planning. More specifically, we welcome studies applying DMDU (Decision-Making under Deep Uncertainty) approaches to infrastructure risk modelling.
6) Progressing the achievement of global goals (e.g. SDGs) in the context of resilient infrastructure and the advancement of accessible infrastructure to the global population.

Extreme climate and weather events, associated disasters and emergent risks are becoming increasingly critical in the context of global environmental change and interact with other stressors. They are a potential major threat to reaching the Sustainable Development Goals (SDGs) and one of the most pressing challenges for future human well-being.
This session explores the linkages between extreme climate and weather events, associated disasters, societal dynamics and resilience. Emphasis is laid on 1) Which impacts are caused by extreme climate events (including risks emerging from compound events) and cascades of impacts on various aspects of ecosystems and societies? 2) Which feedbacks across ecosystems, infrastructures and societies exist? 3) What are key obstacles towards societal resilience and reaching the SDGs, while facing climate extremes? 4) What can we learn from past experiences? 5) What local to global governance arrangements best support equitable and sustainable risk reduction?
We welcome empirical, theoretical and modelling studies from local to global scale from the fields of natural sciences, social sciences, humanities and related disciplines.

Through a wealth of geospatial data, growing computational power, and demonstrated success of application across many fields, artificial intelligence (in particular, machine learning) promises to advance our understanding of natural hazards and our ability to predict and respond to natural disasters. The ITU/WMO/UNEP Focus Group AI for Natural Disaster Management (FG-AI4NDM) is building a community of experts and stakeholders to identify best practices in the use of AI for data processing, improved modeling across spatiotemporal scales, and providing effective communication. This multidisciplinary FG-AI4NDM-session invites contributions addressing challenges related to floods, landslides, earthquakes, volcanic eruptions, tsunamis, among others, as well as multi-hazard. It also welcomes presentations on novel AI methods (including advances in automated annotation, explainability, etc.), which are hazard agnostic.
Abstracts are solicited related to the understanding and prediction of weather, climate and geophysical extremes, from both an applied sciences and theoretical viewpoint.
In this session we propose to group together the traditional geophysical sciences and more mathematical/statistical approaches to the study of extremes. We aim to highlight the complementary nature of these two viewpoints, with the aim of gaining a deeper understanding of extreme events.
Potential topics of interest include but are not limited to the following:
· How extremes have varied or are likely to vary under climate change;
· How well climate models capture extreme events;
· Attribution of extreme events;
· Emergent constraints on extremes;
· Linking dynamical systems extremes to geophysical extremes;
· Extremes in dynamical systems;
· Downscaling of weather and climate extremes.
· Linking the dynamics of climate extremes to their impacts

One of the big challenges in Earth system science consists in providing reliable climate predictions on sub-seasonal, seasonal, decadal and longer timescales. The resulting data have the potential to be translated into climate information leading to a better assessment of global and regional climate-related risks.
The latest developments and progress in climate forecasting on subseasonal-to-decadal and longer timescales will be discussed and evaluated. This will include presentations and discussions of predictions for the different time horizons from dynamical ensemble and statistical/empirical forecast systems, as well as the aspects required for their application: forecast quality assessment, multi-model combination, bias adjustment, downscaling, exploration of artificial-intelligence methods, etc.
Following the new WCRP strategic plan for 2019-2029, prediction enhancements are solicited from contributions embracing climate forecasting from an Earth system science perspective. This includes the study of coupled processes between atmosphere, land, ocean, and sea-ice components, as well as the impacts of coupling and feedbacks in physical, chemical, biological, and human dimensions. Contributions are also sought on initialization methods that optimally use observations from different Earth system components, on assessing and mitigating the impacts of model errors on skill, and on ensemble methods.
We also encourage contributions on the use of climate predictions for climate impact assessment, demonstrations of end-user value for climate risk applications and climate-change adaptation and the development of early warning systems.
A special focus will be put on the use of operational climate predictions (C3S, NMME, S2S), results from the CMIP5-CMIP6 decadal prediction experiments, and climate-prediction research and application projects.
An increasingly important aspect for climate forecast's applications is the use of most appropriate downscaling methods, based on dynamical or statistical approaches or their combination, that are needed to generate time series and fields with an appropriate spatial or temporal resolution. This is extensively considered in the session, which therefore brings together scientists from all geoscientific disciplines working on the prediction and application problems.

This session merges CL3.1.3 “Climate change and other drivers of environmental change: Developments, interlinkages and impacts in regional seas and coastal regions” focused on regional seas and coastal regions worldwide, and CL3.1.4 “Climate change in Mediterranean-type climate regions” focused on the Mediterranean-type climates, with a very similar scope: how climate change and other drivers affect these regions now and in the future.
Regional climate change interacts with many other man-made perturbations in both natural and anthropogenic coastal environments. Regional climate change is one of multiple drivers, which have a continuing impact on terrestrial, aquatic and socio-economic (resp. human) environments. These drivers interact with regional climate change in ways, which are not completely understood.
A Mediterranean-type climate is characterized by mild, wet winters and hot, dry summers as classified with the Koppen-Geiger approach that is well suited for identifying and analyzing the impacts of climate change on natural and anthropic ecosystems. Mediterranean climate regions (MCRs) are located in transitional midlatitude regions like the Mediterranean basin area, western coastal North America and small coastal areas of western South America, southern Africa and southern Australia. The transitional character with sharp spatial gradients makes them highly vulnerable to climate change. For all MCRs, the future holds high risks and uncertainty on issues like loss in biodiversity, increase in aridity, ecological change, requiring innovative approaches to climate adaptation and mitigation.
This session focuses on the connections and interrelations between climate change and other drivers of environmental change in MCRs, regional seas and coastal regions. It intends to strengthen the exchanges among the communities involved to better understand and share commonalities and differences and to provide an overview of the current state of knowledge of the complicated interplay of different factors affecting climate change. This exchange may help identify and prepare shared solutions and practices. Studies focused on physical (including extremes, teleconnections, hydrological cycle) and biogeochemical (including biodiversity) aspects of Mediterranean and other coastal climate regions, focusing on observed past changes, future climate projections, as well as related social aspects including indigenous knowledge in mitigating climate risks will be treated.
An increasing number of single model large ensemble simulations from Global Climate Models (GCM), Earth System Models (ESM), or Regional Climate Models (RCM) have been generated over recent years, to investigate internal variability and forced changes of the climate system — and to aid the interpretation of the observational record by providing a range of historical climate trajectories that could have been. The increased availability of large ensembles also enables new and inter-disciplinary applications beyond large-scale climate dynamics.
This session invites studies using large GCM, ESM, or RCM ensembles looking at the following topics: 1) Reinterpretation of the observed record in light of internal variability; 2) forced changes in internal variability; 3) development of new approaches to attribute and study observed events or trends; 4) impacts of natural climate variability; 5) assessment of extreme and compound event occurrence; 6) combining single model large ensembles with CMIP archives for robust decision making; 7) large ensembles as testbeds for method development.
We welcome research across all components of the Earth system. Examples include topics ranging from climate dynamics, hydrology and biogeochemistry to research on the role of internal variability in impact studies, focused for example on agriculture, air pollution or energy generation and consumption. We particularly invite studies that apply novel methods or cross-disciplinary approaches to leverage the potential of large ensembles.

Climate impact and adaptation research has made considerable progress in various fields in the recent years. However, the concrete implementation on the ground needs to be improved.
Local decision makers are facing several challenges with regard to climate adaptation. At the center of this process lies the coupling of climate, impact and risk (incl. vulnerability) models in order to identify future climate risk levels. Finding and correctly using the necessary data in climate impacts and risks assessments and planning for climate action is not without challenges for specialists from other fields.
While climate modelling and technical integration of diverse model data are crucial, social science as well as interdisciplinary perspectives are essential to assess local adaptation capacities, the costs and benefits of adaptive measures and to ensure the usability and transferability of the climate services. Similarly important is capacity building and trainings on properly using, interpreting and communicating climate and impact information.
This session touches upon innovative ways to address theses challenges. It also supports exchange on experiences in impact and adaptation studies, using all kinds of climate data. Former participants from the C3S ULS and IS-ENES3 training events are particularly encouraged to join.
This session discusses approaches and challenges towards the support of climate change adaptation and disaster risk reduction. Central to the discussion is the question how such services can be developed in a stringent co-design process that integrates different natural and social science disciplines as well as users and practitioners. We are therefore seeking for contributions that discuss:
• Actionable services for regional decision-making in regional climate adaptation and disaster risk reduction and challenges in the interaction between researchers and decision makers
• New scientific insights into regional climate and impact modelling (data interfaces and harmonization)
• Assessing local climate adaptation capacities and measures in an integrated way
• New insights into transdisciplinary processes in climate change adaptation
• Data availability for climate impact studies and methods for dealing with limited data availability as well as the opposite, a large number of seemingly similar datasets.
• Experiences with existing tools or newly developed tools for data processing
The International Monitoring System (IMS) of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) senses the solid Earth, the oceans and the atmosphere with a global network of seismic, infrasound, and hydroacoustic sensors as well as detectors for atmospheric radioactivity. The primary purpose of the IMS data is for nuclear explosion monitoring regarding all aspects of detecting, locating and characterizing nuclear explosions and their radioactivity releases. On-site verification technologies apply similar methods on smaller scales as well as geophysical methods such as ground penetrating radar and geomagnetic surveying with the goal of identifying evidence for a nuclear explosion close to ground zero. Papers in this session address advances in the sensor technologies, new and historic data, data collection, data processing and analysis methods and algorithms, uncertainty analysis, machine learning and data mining, experiments and simulations including atmospheric transport modelling. This session also welcomes papers on applications of the IMS and OSI instrumentation data. This covers the use of IMS data for disaster risk reduction such as tsunami early warning, earthquake hazard assessment, volcano ash plume warning, radiological emergencies and climate change related monitoring. The scientific applications of IMS data establish another large range of topics, including acoustic wave propagation in the Earth crust, stratospheric wind fields and gravity waves, global atmospheric circulation patterns, deep ocean temperature profiles and whale migration. The use of IMS data for such purposes returns a benefit with regard to calibration, data analysis methods and performance of the primary mission of monitoring for nuclear explosions.

Karst environments are characterized by distinctive landforms and unique hydrological behaviors. Karst systems are extremely complex, heterogeneous and very difficult to manage, because their formation and evolution are controlled by a wide range of geological, hydrological, geochemical and biological processes, and are extremely variable in time and space. Furthermore, karst systems are highly vulnerable to a variety of hazards, due to the direct connection between the surface and subsurface through the complex networks of conduits and caves.
In karst, any interference is likely to have irreversible impacts and disturb the natural balance of the elements and processes. The great variability and unique connectivity may result in serious engineering problems: on one hand, karst groundwater resources are easily contaminated by pollution because of the rapidity of transmission through conduit flow, and remediation action, when possible, could be very expensive and require a long time; on the other hand, the presence of karst conduits that weakens the strength of the rock mass may lead to serious natural and human-induced hazards. The design and development of engineering projects in karst environments thus should necessarily require: 1) an enhanced understanding of the natural processes governing the initiation and evolution of karst systems through both field and modelling approaches, and 2) specific interdisciplinary approaches aimed at mitigating the detrimental effects of hazardous processes and environmental problems.
This session calls for abstracts on research from karst areas worldwide related to geomorphology, hydrogeology, engineering geology, hazard mitigation in karst environments in the context of climate change and increasing human disturbance.

On 9 August 2021, the Intergovernmental Panel on Climate Change (IPCC) released the first volume of its 6th Assessment Report (AR6). The Working Group I contribution to the Report (Climate Change 2021: The Physical Science Basis) synthesises over 14,000 publications and represents the most comprehensive and up-to-date assessment of the climate system and climate change. Crucially, the Report highlights the unprecedented and potentially irreversible influence of anthropogenic climate forcing, and for the first time, explicitly states that human influence on the climate system is unequivocal.
This short course will be a panel discussion where authors and contributors of Working Group I unpack how the IPCC 6th Assessment Report (AR6) is produced, provide personal behind-the-scenes insight on its development, and discuss its global impact, including how it is used to inform policy. Authors of the report will share their experiences of working on the report before and through the COVID pandemic. Panelists will also emphasise various ways in which scientists of all career stages can contribute to the IPCC process. Ample time will be allocated for open discussion for the audience to ask related questions to the panelists.
For more information about the AR6 please visit the IPCC website: https://www.ipcc.ch/.
Meet editors of internationally renowned journals in geo- and biogeoscience and gain exclusive insights into the publishing process. After a short introduction into some basics, we will start exploring various facets of academic publishing with short talks given by the editors on
- What are the duties and roles of editors, authors and reviewers?
- How to choose a suitable journal for your manuscript and what is important for early career authors?
- How can early career scientists get involved in successful peer-reviewing?
- What is important for appropriate peer-reviewing?
- What are ethical aspects and responsibilities of publishing?
Together with the audience and the editors, we will have an open discussion of the key steps and factors shaping the publication process of a manuscript. This short course aims to provide early career scientists across several EGU divisions (e.g. AS, BG, CL, GM, NH, SSP and SSS) the opportunity of using first hand answers of experienced editors of international journals to successfully publish their manuscripts and get aware of the potentials and pitfalls in academic publishing.

Metallurgical slags are generated as a by-product of smelting during ironmaking, steelmaking, and the production of ferroalloys and non-ferrous metals. The formation conditions result in complex (geo)chemical and mineralogical characteristics unique to slags alone. Historically slags have been discarded as a waste product and, through release of potentially toxic trace elements, represent a hazard to the environment and human health. However, increasingly we are realizing the resource potential of what was previously thought of as waste, thus reducing the environmental impact and taking a step closer to a circular economy.
The aim of this short course is to is to give an overview on the environmental geochemistry and resource potential of metallurgical slags by summarizing processes for the generation of slags, describing their chemical and mineralogical characteristics, outlining the fundamental geochemistry that propels slag weathering, and illustrating the utilization of slags and resource recovery of valuable metals from slags. This short course is a follow up of a book entitled “Metallurgical Slags: Environmental geochemistry and Resource Potential” published in 2021 by the Royal Society of Chemistry and gives an overview useful for the environmental geochemists, geologists, mining and civil engineers, waste and resource managers, and all those interested and inspired by a circular economy and minimizing our environmental footprint on planet Earth.

1. Presentation of the book: Metallurgical Slags: Environmental Geochemistry and Resource Potential (Vojtěch Ettler and Nadine Piatak)
2. Metallurgical overview and production of slags (Elias Matinde, MINTEK, South Africa)
3. Geochemistry and mineralogy of slags (Nadine Piatak, USGS, USA)
4. Weathering of slags (Jakub Kierczak, University of Wroclaw, Poland)
5. Leaching properties and environmental fate of slags (Vojtech Ettler, Charles University, Czech Republic)

Changes in temperature in landslide bodies can be the result of external forcing (climatic or geothermal) as well as the consequence of frictional heat dissipation. Understanding and quantifying the mechanical response of geomaterials under thermal forcing can be crucial for predicting the initiation and fate of landslides, and the associated risk. Depending on the scale of interest, different modelling strategies have been developed, spanning from physically-based fully-coupled models accounting for micro-scale behaviours to large-scale geostatistical approaches. This short course aims to offer an overview of these modelling strategies with particular attention to state-of-the-art advances. The session is organized in cooperation with NhET (Natural hazard Early career scientists Team).

We will give an overview of selected methods to account for temperature in landslide modelling focusing on:
In his seminal work "Weather Prediction by Numerical Process" in 1922, Lewis Fry Richardson proposed his famous cascade picture qualitatively, for a turbulent flow where the energy is transferred from large scale structures to small scale ones, until reaching viscosity scales where it is converted to heat. This picture now has been widely adopted to describe different type of turbulent phenomena, for not only the classical hydrodynamic turbulence, but also, not limited to, the movement of atmosphere and oceans.
After 100 years of developments, the concept of cascades has been extended significantly. Now, it describes mainly the nonlinear interactions crossing a large range of scales where scale invariants might emerge spontaneously. More precisely, balances between the external forcing and the dissipation are expected for a turbulent system. However, due to the complexity of atmospheric or oceanic systems, such as earth rotation, stratification, large aspect ratio, mesoscale eddies, ocean current, tidal, waves, etc., the exact balance is still unknown. We still lack an efficient methodology to diagnose the scale-to-scale energy or other physical quantities fluxes to characterize the cascade quantitatively, e.g., strength, direction, etc.
With the increasing capability of remote sensing, computational fluid dynamics, field observation, etc., we have accumulated a large amount of field data. It is now a suitable time to celebrate the 100th Anniversary of Richardson's idea of cascades in the geosciences, and to understand it quantitatively.
This interdisciplinary session welcomes theoretical, methodological, laboratory, data analysis works that aim to characterize the cascade in atmosphere and oceans and other fields.

The dynamics of the Earth system and its components is highly nonlinear. In particular, several subsystems have been suggested to react abruptly at critical levels of anthropogenic forcing. Well-known examples of such Tipping Elements include the Atlantic Meridional Overturning Circulation, the polar ice sheets and sea ice, tropical and boreal forests, as well as the Asian monsoon systems. Interactions between the different Tipping Elements may either have stabilizing or destabilizing effects on the other subsystems, potentially leading to cascades of abrupt transitions. The critical forcing levels at which abrupt transitions occur have recently been associated with Tipping Points.
It is paramount to determine the critical forcing levels (and the associated uncertainties) beyond which the systems in question will abruptly change their state, with potentially devastating climatic, ecological, and societal impacts. For this purpose, we need to substantially enhance our understanding of the dynamics of the Tipping Elements and their interactions, on the basis of paleoclimatic evidence, present-day observations, and models spanning the entire hierarchy of complexity. Moreover, to be able to mitigate - or prepare for - potential future transitions, early warning signals have to be identified and monitored in both observations and models.
This multidisciplinary session invites contributions that address Tipping Points in the Earth system from the different perspectives of all relevant disciplines, including
- the mathematical theory of abrupt transitions in (random) dynamical systems,
- paleoclimatic studies of past abrupt transitions,
- data-driven and process-based modelling of past and future transitions,
- early-warning signals
- the implications of abrupt transitions for Climate sensitivity and response,
- ecological and societal impacts, as well as
- decision theory in the presence of uncertain Tipping Point estimates

Theoretical and model studies show that the ocean is a chaotic system which spontaneously generates a strong, multi-scale intrinsic chaotic variability: uncertainties in ocean model initial states may grow and strongly affect the simulated variability up to multi-decadal and basin scales, with or without coupling to the atmosphere. In addition, ocean simulations require both the use of subgrid-scale parameterizations that crudely mimic unresolved processes, and the calibration of the parameters associated with these parameterizations. In this context of multiple uncertainties, oceanographers are increasingly adopting ensemble simulation strategies, probabilistic analysis methods, and developing stochastic parameterizations for modeling and understanding ocean variability.
Presentations are solicited about the conception and analysis of ocean ensemble simulations, the characterization of ocean model uncertainties, and the development of stochastic parameterizations for ocean models. The session will also cover the dynamics and structure of chaotic ocean variability, its relationship with atmospheric variability, and the use of dynamical system or information theories for the investigation of oceanic variability. We welcome as well studies about the propagation of chaotic ocean variability towards other components of the climate system, about its consequences regarding ocean predictability, operational forecasts, detection and attribution of climate signals, climate simulations and projections.

Analysis of the energy transfers between and within climate components has been at the core of many step changes in the understanding of the climate system. Large-scale atmospheric circulation, hydrological cycle and heat/moisture transports are tightly intertwined through radiative and heat energy absorption and transports that are sensitive to multiple forcings and feedbacks. Cross-equatorial energy exchanges by the ocean and atmosphere couple Hadley Circulation and Atlantic Overturning circulation, modulating the location and intensity of the ITCZ and the amount of precipitation in monsoon regions. In the extra-tropics, Rossby waves affect the distribution of precipitation and eddy activity, shaping the meridional heat transport from the low latitudes towards the Poles through intermittent events of persistent and co-located blockings and the occurrence of extreme heat waves or cold outbreaks. In the ocean, understanding of energy transfers from large-scale circulation to the internal wave field, through mesoscale and submesoscale eddies, is the basis for the development of new parameterizations and significant modelling advances.
We invite submissions addressing the interplay between Earth’s energy exchanges and the general circulation using modeling, theory, and observations. We encourage contributions on the forced response and natural variability of the general circulation, understanding present-day climate and past and future changes, and impacts of global features and change on regional climate.

This session focuses on advances in theoretical, methodological and applied studies in hydrologic and broader earth system dynamics, regimes, transitions and extremes, along with their physical understanding, predictability and uncertainty, across multiple spatiotemporal scales.
The session further encourages discussion on interdisciplinary physical and data-based approaches to system dynamics in hydrology and broader geosciences, ranging from novel advances in stochastic, computational, information-theoretic and dynamical system analysis, to cross-cutting emerging pathways in information physics.
Contributions are gathered from a diverse community in hydrology and the broader geosciences, working with diverse approaches ranging from dynamical modelling to data mining, machine learning and analysis with physical process understanding in mind.
The session further encompasses practical aspects of working with system analytics and information theoretic approaches for model evaluation and uncertainty analysis, causal inference and process networks, hydrological and geophysical automated learning and prediction.
The operational scope ranges from the discussion of mathematical foundations to development and deployment of practical applications to real-world spatially distributed problems.
The methodological scope encompasses both inverse (data-based) information-theoretic and machine learning discovery tools to first-principled (process-based) forward modelling perspectives and their interconnections across the interdisciplinary mathematics and physics of information in the geosciences.
Take part in a thrilling session exploring and discussing promising avenues in system dynamics and information discovery, quantification, modelling and interpretation, where methodological ingenuity and natural process understanding come together to shed light onto fundamental theoretical aspects to build innovative methodologies to tackle real-world challenges facing our planet.

The virus is still with us, with more potent variants. It remains the most immediate challenge for geosciences and health, including its impacts on geoscience development (data collection, training, dissemination) and the achievement of the UN Sustainable Development Goals, in particular that urban systems should increase well-being and health.
Long-term visions based on transdisciplinary scientific advances are therefore essential. As a consequence, this session, like the ITS1.1 session in 2021, calls for contributions based on data-driven and theory-based approaches to health in the context of global change. This includes :
- main lessons from lockdowns?
- how to get the best scientific results during a corona pandemic?
- how to manage field works, geophysical monitoring and planetary missions?
- qualitative improvements in epidemic modelling, with nonlinear, stochastic, and complex system science approaches;
- eventual interactions between weather and/or climate factors and epidemic/health problems
- new surveillance capabilities (including contact tracing), data access, assimilation and multidimensional analysis techniques;
- a fundamental revision of our urban systems, their greening and their need for mobility;
- a special focus on urban biodiversity, especially to better manage virus vectors;
- urban resilience must include resilience to epidemics, and therefore requires revisions of urban governance.

The Earth's climate is highly variable on all spatial and temporal scales, and this has direct consequences for society. For example, changes in variability (spatial or temporal) can impact the recurrence frequency of extreme events. Yet it is unclear if a warmer future is one with more or with less climate variability, and at which scales, as a multitude of feedbacks is involved and the instrumental record is short.
The session is multidisciplinary and brings together people working in the geosciences, atmospheric science, oceanography, glaciology, paleoclimatology and environmental physics, to examine the complementarity of ideas and approaches. Members of the PAGES working group on Climate Variability Across Scales (CVAS) and others are welcome.
This session also aims to nurture the development of fractals, multifractals and related nonlinear methodologies applicable to a wide range of geophysical systems and their multiscale interactions. Theories considering scalar and vector fields, applications ranging from urban geosciences (e.g., land use patterns, water management, ecosystems) to atmospheric and oceanic turbulence (e.g., wind energy, mesoscale scaling anisotropy) and climate (e.g., multiscale evolution of extremes), analysis of in-situ, remotely sensed and simulated data are of interest.
Our aim is to provide a forum to present work on:
1- the characterization of climate dynamics using a variety of techniques (e.g. scaling and multifractal techniques and models, recurrence plots, or variance analyses) to study its variability including periodicities, noise levels, or intermittency)
2- the relationship between changes in the mean state (e.g. glacial to interglacial or preindustrial to present to future), and higher-order moments of relevant climate variables, to changes in extreme-event occurrence and the predictability of climate
3- the role of ocean, atmosphere, cryosphere, and land-surface processes in fostering long-term climate variability through linear – or nonlinear – feedbacks and mechanisms
4- the attribution of climate variability to internal dynamics, or the response to natural (volcanic or solar) and anthropogenic forcing
5- the interaction of external forcing (e.g. orbital forcing) and internal variability such as mechanisms for synchronization and pacing of glacial cycles
6- the characterization of probabilities of extremes, including linkage between slow climate variability and extreme event recurrence
The goal of this session is to reconcile short-time/small-scale and long-time/large-scale observations, including geodynamic processes such as subduction, collision, rifting, or mantle lithosphere interactions. Despite the remarkable advances in experimental rock mechanics, the implications of rock-mechanics data for large temporal and spatial scale tectonic processes are still not straightforward, since the latter are strongly controlled by local lithological stratification of the lithosphere, its thermal structure, fluid content, tectonic heritage, metamorphic reactions, and deformation rates.
Mineral reactions have mechanical effects that may result in the development of pressure variations and thus are critical for interpreting microstructural and mineral composition observations. Such effects may fundamentally influence element transport properties and rheological behavior.
Here, we encourage presentations focused on the interplay between metamorphic processes and deformation on all scales, on the rheological behavior of crustal and mantle rocks, and time scales of metamorphic reactions in order to discuss
(1) how and when up to GPa-level differential stress and pressure variations can be built and maintained at geological timescales and modeling of such systems,
(2) deviations from lithostatic pressure during metamorphism: fact or fiction?
(3) the impact of deviations from lithostatic pressure on geodynamic reconstructions.
(4) the effect of porous fluid and partial melting on the long-term strength.
We, therefore, invite the researchers from different domains (rock mechanics, petrographic observations, geodynamic and thermo-mechanical modeling) to share their views on the way forward for improving our knowledge of the long-term rheology and chemo-thermo-mechanical behavior of the lithosphere and mantle.
Environmental systems often span spatial and temporal scales covering different orders of magnitude. The session is oriented toward collecting studies relevant to understand multiscale aspects of these systems and in proposing adequate multi-platform and inter-disciplinary surveillance networks monitoring tools systems. It is especially aimed to emphasize the interaction between environmental processes occurring at different scales. In particular, special attention is devoted to the studies focused on the development of new techniques and integrated instrumentation for multiscale monitoring of high natural risk areas, such as volcanic, seismic, energy exploitation, slope instability, floods, coastal instability, climate changes, and another environmental context.
We expect contributions derived from several disciplines, such as applied geophysics, geology, seismology, geodesy, geochemistry, remote and proximal sensing, volcanology, geotechnical, soil science, marine geology, oceanography, climatology, and meteorology. In this context, the contributions in analytical and numerical modeling of geological and environmental processes are also expected.
Finally, we stress that the inter-disciplinary studies that highlight the multiscale properties of natural processes analyzed and monitored by using several methodologies are welcome.

Downscaling aims to process and refine global climate model output to provide information at spatial and temporal scales suitable for impact studies. In response to the current challenges posed by climate change and variability, downscaling techniques continue to play an important role in the development of user-driven climate information and new climate services and products. In fact, the "user's dilemma" is no longer that there is a lack of downscaled data, but rather how to select amongst the available datasets and to assess their credibility. In this context, model evaluation and verification is growing in relevance and advances in the field will likely require close collaboration between various disciplines.
Furthermore, epistemologists have started to revisit current practices of climate model validation. This new thread of discussion encourages to clarify the issue of added value of downscaling, i.e. the value gained through adding another level of complexity to the uncertainty cascade. For example, the ‘adequacy-for-purpose view’ may offer a more holistic approach to the evaluation of downscaling models (and atmospheric models, in general) as it considers, for example, user perspectives next to a model’s representational accuracy.
In our session, we aim to bring together scientists from the various geoscientific disciplines interrelated through downscaling: atmospheric modeling, climate change impact modeling, machine learning and verification research. We also invite philosophers of climate science to enrich our discussion about novel challenges faced by the evaluation of increasingly complex simulation models.
Contributions to this session may address, but are not limited to:
- newly available downscaling products,
- applications relying on downscaled data,
- downscaling method development, including the potential for machine learning,
- bias correction and statistical postprocessing,
- challenges in the data management of kilometer-scale simulations,
- verification, uncertainty quantification and the added value of downscaling,
- downscaling approaches in light of computational epistemology.

Rainfall is a “collective” phenomenon emerging from numerous drops. Understanding the relation between the physics of individual drops and that of a population of drops remains an open challenge, both scientifically and at the level of practical implications. This remains true also for solid precipitation. Hence, it is much needed to better understand small scale spatio-temporal precipitation variability, which is a key driving force of the hydrological response, especially in highly heterogeneous areas (mountains, cities). This hydrological response at the catchment scale is the result of the interplay between the space-time variability of precipitation, the catchment geomorphological / pedological / ecological characteristics and antecedent hydrological conditions. Therefore, (1) accurate measurement and prediction of the spatial and temporal distribution of precipitation over a catchment and (2) the efficient and appropriate description of the catchment properties are important issues in hydrology.
This session will bring together scientists and practitioners who aim to measure and understand precipitation variability from drop scale to catchment scale as well as its hydrological consequences. Contributions addressing one or several of the following topics are especially targeted:
- Novel techniques for measuring liquid and solid precipitation variability at hydrologically relevant space and time scales (from drop to catchment scale), from in situ measurements to remote sensing techniques, and from ground-based devices to spaceborne platforms. Innovative comparison metrics are welcomed;
- Precipitation drop (or particle) size distribution and its small scale variability, including its consequences for precipitation rate retrieval algorithms for radars, commercial microwave links and other remote sensors;
- Novel modelling or characterization tools of precipitation variability from drop scale to catchment scale from various approaches (e.g. scaling, (multi-)fractal, statistic, deterministic, numerical modelling);
- Novel approaches to better identify, understand and simulate the dominant microphysical processes at work in liquid and solid precipitation.
- Applications of measured and/or modelled precipitation fields in catchment hydrological models for the purpose of process understanding or predicting hydrological response.

The assessment of precipitation variability and uncertainty is crucial in a variety of applications, such as flood risk forecasting, water resource assessments, evaluation of the hydrological impacts of climate change, determination of design floods, and hydrological modelling in general. This session aims to gather contributions on research, advanced applications, and future needs in the understanding and modelling of precipitation variability, and its sources of uncertainty.
Contributions focusing on one or more of the following issues are particularly welcome:
- Novel studies aimed at the assessment and representation of different sources of uncertainty versus natural variability of precipitation.
- Methods to account for accuracy in precipitation time series due to, e.g., change and improvement of observation networks.
- Uncertainty and variability in spatially and temporally heterogeneous multi-source precipitation products.
- Estimation of precipitation variability and uncertainty at ungauged sites.
- Precipitation data assimilation.
- Process conceptualization and approaches to modelling of precipitation at different spatial and temporal scales, including model parameter identification and calibration, and sensitivity analyses to parameterization and scales of process representation.
- Modelling approaches based on ensemble simulations and methods for synthetic representation of precipitation variability and uncertainty.
- Scaling and scale invariance properties of precipitation fields in space and/or in time.
- Physically and statistically based approaches to downscale information from meteorological and climate models to spatial and temporal scales useful for hydrological modelling and applications.

Space and astrophysical plasmas are typically in a turbulent state, exhibiting strong fluctuations of various quantities over a broad range of scales. These fluctuations are non-linearly coupled and this coupling may lead to a transfer of energy (and other quantities such as cross helicity, magnetic helicity) from large to small scales and to dissipation. Turbulent processes are relevant for the heating of the solar wind and the corona, acceleration of energetic particles. Many aspects of the turbulence are not well understood, in particular, the injection and onset of the cascade, the cascade itself, the dissipation mechanisms, as well as the role of specific phenomena such as the magnetic reconnections, shock waves, expansion, and plasma instabilities and their relationship with the turbulent cascade and dissipation.
This session will address these questions through discussion of observational, theoretical, numerical, and laboratory work to understand these processes. This session is relevant to many currently operating missions (e.g., Wind, Cluster, MMS, STEREO, THEMIS, Van Allen Probes, DSCOVR) and in particular for the Solar Orbiter and the Parker Solar Probe.

Big data analytics will have a primary role in addressing modern challenges such as climate change, disaster management, public health and safety, resources management, and logistics. Most of these phenomena are characterized by spatio-temporal patterns that have been traditionally investigated using linear statistical approaches, as in the case of physically-based models and geostatistical models. Additionally, the rising attention toward machine learning, the variety of modern technologies generating massive volumes of geospatial data at local and global scales, and the rapid growth of computational resources, open new horizons in understanding, modelling, and forecasting complex spatio-temporal systems using stochastics non-linear models.
This session aims at exploring the new challenges and opportunities opened by the spread of big geospatial datasets and data-driven statistical learning approaches in Earth and Soil Sciences. We invite cutting-edge contributions related to methods of spatio-temporal geostatistics or data mining on topics that include, but are not limited to:
- advances in spatio-temporal modeling using geostatistics and machine learning;
- software and infrastructure development for geospatial data;
- uncertainty quantification and representation;
- innovative techniques of knowledge extraction based on clustering, pattern recognition and, more generally, data mining.
The main applications will be closely related to the research in environmental sciences and quantitative geography. A non-complete list of possible applications includes:
- natural and anthropogenic hazards (e.g. floods; landslides; earthquakes; wildfires; soil, water, and air pollution);
- interaction between geosphere and anthroposphere (e.g. land degradation; urban sprawl);
- socio-economic sciences, characterized by the spatial and temporal dimension of the data (e.g. public health management, census data; transport; commuter traffic).
This session collects the abstract submitted to the session “Strategies and Applications of AI and ML in a Spatiotemporal Context” and “Spatio-temporal Data Science: Theoretical Advances and Applications in Computational Geosciences”.

Modelling past climate states, and the transient evolution of Earth’s climate remains challenging. Time periods such as the Paleocene, Eocene, Pliocene, the Last Interglacial, the Last Glacial Maximum or the mid-Holocene span across a vast range of climate conditions. At times, these lie far outside the bounds of the historical period that most models are designed and tuned to reproduce. However, our ability to predict future climate conditions and potential pathways to them is dependent on our models' abilities to reproduce just such phenomena. Thus, our climatic and environmental history is ideally suited to thoroughly test and evaluate models against data, so they may be better able to simulate the present and make future climate projections.
We invite papers on palaeoclimate-specific model development, model simulations and model-data comparison studies. Simulations may be targeted to address specific questions or follow specified protocols (as in the Paleoclimate Modelling Intercomparison Project – PMIP or the Deep Time Model Intercomparison Project – DeepMIP). They may include anything between time-slice equilibrium experiments to long transient climate simulations (e.g. transient simulations covering the entire glacial cycle as per the goal of the PalMod project) with timescales of processes ranging from synoptic scales to glacial cycles and beyond. Comparisons may include past, historical as well as future simulations and focus on comparisons of mean states, gradients, circulation or modes of variability using reconstructions of temperature, precipitation, vegetation or tracer species (e.g. δ18O, δD or Pa/Th).
Evaluations of results from the latest phase of PMIP4-CMIP6 are particularly encouraged. However, we also solicit comparisons of different models (comprehensive GCMs, isotope-enabled models, EMICs and/or conceptual models) between different periods, or between models and data, including an analysis of the underlying mechanisms as well as contributions introducing novel model or experimental setups.

Unsupervised, supervised, semi-supervised as well as reinforcement learning are now increasingly used to address Earth system related challenges.
Machine learning could help extract information from numerous Earth System data, such as in-situ and satellite observations, as well as improve model fidelity through novel parameterisations or speed-ups. This session invites submissions spanning modelling and observational approaches towards providing an overview of the state-of-the-art of application of these novel methods for predicting and monitoring our earth system. This includes (but it is not restricted to):
- the use of machine learning to improve forecast skill
- generate significant speedups
- design new parameterization schemes
- emulate numerical models.
Please consider submitting abstracts focussed on ML applied to observations and modelling of climate processes to the companion "ML for Climate Science" session.
Recent developments in machine learning (ML) are transforming Earth observation data analysis and modelling of the Earth system and its constituent processes. While statistical models have been used for a long time, state-of-the-art machine and deep learning algorithms allow encoding non-linear, spatio-temporal relationships robustly without sacrificing interpretability. These advances have the potential to accelerate climate science by improving our understanding of the underlying processes, reducing and better quantifying uncertainty, and even making predictions directly from observations across different spatio-temporal scales.
This session aims to provide a venue to present the latest progress in the use of ML applied to all aspects of climate science including, but not limited to:
- Causal discovery and inference
- Learning (causal) process and feature representations in observations
- Hybrid models (physically informed ML)
- Novel detection and attribution approaches
- Probabilistic modelling and uncertainty quantification
- Explainable AI applications to climate science
Please consider submitting abstracts focussed on ML for model improvement, particularly for near-term (including seasonal) forecasting to the companion “ML for Earth System modelling” session.
Statistical post-processing techniques for weather, climate, and hydrological forecasts are powerful approaches to compensate for effects of errors in model structure or initial conditions, and to calibrate inaccurately dispersed ensembles. These techniques are now an integral part of many forecasting suites and are used in many end-user applications such as wind energy production or flood warning systems. Many of these techniques are flourishing in the statistical, meteorological, climatological, hydrological, and engineering communities. The methods range in complexity from simple bias correction up to very sophisticated distribution-adjusting techniques that take into account correlations among the prognostic variables.
At the same time, a lot of efforts are put in combining multiple forecasting sources in order to get reliable and seamless forecasts on time ranges from minutes to weeks. Such blending techniques are currently developed in many meteorological centers.
In this session, we invite presentations dealing with both theoretical developments in statistical post-processing and evaluation of their performances in different practical applications oriented toward environmental predictions, and new developments dealing with the problem of combining or blending different types of forecasts in order to improve reliability from very short to long time scales.

Inverse Problems are encountered in many fields of geosciences. One class of inverse problems, in the context of predictability, is assimilation of observations in dynamical models of the system under study. Furthermore, objective quantification of the uncertainty during data assimilation, prediction and validation is the object of growing concern and interest.
This session will be devoted to the presentation and discussion of methods for inverse problems, data assimilation and associated uncertainty quantification, in ocean and atmosphere dynamics, atmospheric chemistry, hydrology, climate science, solid earth geophysics and, more generally, in all fields of geosciences.
We encourage presentations on advanced methods, and related mathematical developments, suitable for situations in which local linear and Gaussian hypotheses are not valid and/or for situations in which significant model or observation errors are present. Specific problems arise in situations where coupling is present between different components of the Earth system, which gives rise to the so called coupled data assimilation.
We also welcome contributions dealing with algorithmic aspects and numerical implementation of the solution of inverse problems and quantification of the associated uncertainty, as well as novel methodologies at the crossroad between data assimilation and purely data-driven, machine-learning-type algorithms.

One of the big challenges in Earth system science consists in providing reliable climate predictions on sub-seasonal, seasonal, decadal and longer timescales. The resulting data have the potential to be translated into climate information leading to a better assessment of global and regional climate-related risks.
The latest developments and progress in climate forecasting on subseasonal-to-decadal and longer timescales will be discussed and evaluated. This will include presentations and discussions of predictions for the different time horizons from dynamical ensemble and statistical/empirical forecast systems, as well as the aspects required for their application: forecast quality assessment, multi-model combination, bias adjustment, downscaling, exploration of artificial-intelligence methods, etc.
Following the new WCRP strategic plan for 2019-2029, prediction enhancements are solicited from contributions embracing climate forecasting from an Earth system science perspective. This includes the study of coupled processes between atmosphere, land, ocean, and sea-ice components, as well as the impacts of coupling and feedbacks in physical, chemical, biological, and human dimensions. Contributions are also sought on initialization methods that optimally use observations from different Earth system components, on assessing and mitigating the impacts of model errors on skill, and on ensemble methods.
We also encourage contributions on the use of climate predictions for climate impact assessment, demonstrations of end-user value for climate risk applications and climate-change adaptation and the development of early warning systems.
A special focus will be put on the use of operational climate predictions (C3S, NMME, S2S), results from the CMIP5-CMIP6 decadal prediction experiments, and climate-prediction research and application projects.
An increasingly important aspect for climate forecast's applications is the use of most appropriate downscaling methods, based on dynamical or statistical approaches or their combination, that are needed to generate time series and fields with an appropriate spatial or temporal resolution. This is extensively considered in the session, which therefore brings together scientists from all geoscientific disciplines working on the prediction and application problems.

Since its inception, data assimilation has proven to be enormously useful in the most varied fields throughout the Earth Sciences. It is certainly essential in meteorology, where the short-range forecasts would otherwise be almost impossible. In oceanography, its development has been slower, partly due to the smaller number of continuous and stable observations, and partly due to the fewer studies that show the importance of ocean forecasts for societal benefit. However, recently, these techniques are used more and more widely, both in operational oceanography and to produce climate reconstructions. Although the techniques are similar to those used in the atmospheric field, they have to deal with particularities due to the different environment, where the boundary conditions, open and closed, have greater importance, and the sparsity of observations poses unique challenges.
In this session, we welcome contributions describing data assimilation techniques, both methodological and case studies, in the oceanographic field. We welcome presentations of new techniques or new types of observations that cover every aspect of data assimilation, including varied applications of data assimilation, both in coastal seas and the open ocean.

The multitude of processes of various scales occurring simultaneously under strong winds in the air and sea boundary layers presents a true challenge for nonlinear science. We want to understand the physics of these processes, their specific role, their interactions and how they can be probed remotely, how these processes differ from their counterparts under moderate/weak winds. We welcome theoretical, experimental, and numerical works on all aspects of processes in turbulent boundary layers above and below the ocean surface. Although we are particularly interested in the processes and phenomena occurring under strong wind conditions, the works concerned with similar processes under weaker winds which might provide an insight for rough seas are also welcomed. We are also very interested in works on remote sensing of these processes.
The areas of interest include the processes at and in the vicinity of the interface (nonlinear dynamics of surface water, wave-turbulence interactions, wave breaking, generation and dynamics of spray and air bubbles, thermodynamics of the processes in the boundary layers, heat and gas exchange), all the processes above and below the air/water interface, as long as they are relevant for strong wind conditions (such as, e.g. inertial waves generated by changing winds). Relevant nonlinear biological phenomena are also welcomed.
The main aim of the session is to initiate discussion of the multitude of processes active under strong winds across the narrow specializations as a step towards creating an integrated picture. Theoretical, numerical, experimental and observational works are welcomed.

Planktonic organisms live in suspension in marine or fresh waters where they have adapted through the slow process of natural evolution (over hundred of thousands of generations) to the harsh turbulent currents of their environment. Therefore, contrary to what the meaning of their name “marine drifter” might let to speculate, their dynamics is potentially different from the one of material bodies passively transported by fluid flows. It is indeed known that these organisms developed many adaptive strategies involving shape and density regulation, swimming activity, aggregation and other mechanisms in order to be sheltered from or to take advantage of turbulent flow features.
Bloom inceptions, thin layers formation, motility, nutrient and light uptakes, specific Lagrangian dynamics, among others are topics involving phytoplankton and turbulence. Jumps, grazing, contact rates, and vertical migration are, among others, topics concerning zooplankton in turbulence. For all planktonic species, adaptive mechanisms in response not only to mechanical, but also chemical and electro-magnetic (such as luminous) cues are topics of great interest.
This interdisciplinary session will welcome works from marine ecologists, oceanographers, fluid-dynamicists, physicists and mathematical modellers. Contributions in the fields of observation, laboratory experimentations, numerical models (such as Computational Fluid Dynamics simulations of non-spherical or motile particles) are welcome. Both phytoplankton and zooplankton will be considered, as well as marine and freshwater studies.

This session focuses on the non-linear processes that take place in space, laboratory and astrophysical plasma. These processes are usually not separated from one another and often go "hand in hand". Just to mention a few examples, magnetic reconnection is an established ingredient of the turbulence cascade and it is also responsible for the production of turbulence in reconnection outflows; shocks may form in collisional and collisionless reconnection processes and can be responsible for turbulence formation, as for instance in the turbulent magnetosheath; magnetic and velocity-shear driven instabilities triggers plasma turbulence in their non-linear phase and can locally develop in turbulent plasmas. All these non-linear processes are responsible for particle acceleration and plasma heating in the environments where they take place.
We are now in a fortunate time for the investigation of these processes, where we can use a combined approach based on simulations and observations together. Simulations can deliver output in a temporal and spatial range of scales going from fluid to electron kinetic. On the observation side, high cadence measurements of particles and fields, high resolution 3D measurements of particle distribution functions and multipoint measurements make it easier to reconstruct the 3D space surrounding the spacecrafts. In this context, the Parker Solar Probe and the Solar Orbiter mission are opening new research scenarios in heliophysics, providing a consistent amount of new data to be analysed.
This session welcomes simulations, observational, and theoretical works relevant for the study of the above mentioned plasma processes. Particularly welcome this year, will be works focusing on how non-linear processes accelerate particles and produce heating in collisionless plasmas. We also encourage papers proposing new methods in simulation techniques and data analysis, as for example those rooted in Artificial Intelligence and Machine Learning.

This session welcomes contributions presenting advances in, and approaches to, the modelling, monitoring, and forecasting of internal waves in stratified estuaries, lakes and the coastal oсean.
Internal solitary waves (ISWs) and large-amplitude internal wave packets are a commonly observed event in oceans and lakes. In the oceans ISWs are mainly generated by the interaction of the barotropic tides with bottom topography. Large amplitude solitary waves are energetic events that generate strong currents. They can also trap fluid with larvae and sediments in the cores of waves and transport it a considerable distance. ISWs can cause hazards to marine engineering and submarine navigation, and significantly impact marine ecosystems and particle transport in the bottom layer of the ocean and stratified lakes. Contributions studying flows due to internal waves, their origin, propagation and influence on the surrounding environment are thus of broad scientific importance.
The scope of the session involves all aspects of ISWs generation, propagation, transformation and the interaction of internal waves with bottom topography and shelf zones, as well as an evaluation of the role of internal waves in sediment resuspension and transport. Breaking of internal-waves also drives turbulent mixing in the ocean interior that is important for climate ocean models. Discussion of parameterizations for internal-wave driven turbulent mixing in global ocean models is also invited.

Waves in the Earth’s crust are often generated by fractures in the process of their sliding or propagation. Conversely, the waves can trigger fracture sliding or even propagation. The presence of multiple fractures makes geomaterials non-linear. Therefore the analysis of wave propagation and interaction with pre-existing or emerging fractures is central to geophysics. Recently new observations and theoretical concepts were introduced that point out to the limitations of the traditional concept. These are:
• Multiscale nature of wave fields and fractures in geomaterials
• Rotational mechanisms of wave and fracture propagation
• Strong rock and rock mass non-linearity (such as bilinear stress-strain curve with high modulus in compression and low in tension) and its effect on wave propagation
• Apparent negative stiffness associated with either rotation of non-spherical constituents or fracture propagation and its effect on wave propagation
• Triggering effects and instability in geomaterials
• Active nature of geomaterials (e.g., seismic emission induced by stress and pressure wave propagation)
• Non-linear mechanics of hydraulic fracturing
• Synchronization in fracture processes including earhtquakes and volcanic activity
Complex waves are now a key problem of the physical oceanography and atmosphere physics. They are called rogue or freak waves. It may be expected that similar waves are also present in non-linear solids (e.g., granular materials), which suggests the existence of new types of seismic waves.
It is anticipated that studying these and related phenomena can lead to breakthroughs in understanding of the stress transfer and multiscale failure processes in the Earth's crust, ocean and atmosphere and facilitate developing better prediction and monitoring methods.
The session is designed as a forum for discussing these and relevant topics.
We invite presentations on ocean surface waves, and wind-generated waves in particular, their dynamics, modelling and applications. This is a large topic of the physical oceanography in its own right, but it is also becoming clear that many large-scale geophysical processes are essentially coupled with the surface waves, and those include climate, weather, tropical cyclones, Marginal Ice Zone and other phenomena in the atmosphere and many issues of the upper-ocean mixing below the interface. This is a rapidly developing area of research and geophysical applications, and contributions on wave-coupled effects in the lower atmosphere and upper ocean are strongly encouraged.

Internal gravity waves (IGWs) still pose major questions both to the atmospheric and ocean sciences, and to stellar physics. Important issues are IGW radiation from their various relevant sources, IGW reflection at boundaries, their propagation through and interaction with a larger-scale flow, wave-induced mean flow, wave-wave interactions in general, wave breaking and its implications for mixing, and the parameterization of these processes in models not explicitly resolving IGWs. The observational record, both on a global scale and with respect to local small-scale processes, is not yet sufficiently able to yield appropriate constraints. The session is intended to bring together experts from all fields of geophysical and astrophysical fluid dynamics working on related problems. Presentations on theoretical, modelling, experimental, and observational work with regard to all aspects of IGWs are most welcome, including those on major collaborative projects, such as DataWave.

In 2015, the UN Sustainable Development Goals and the Paris Agreement on climate recognized the deteriorating resilience of the Earth system, with planetary-scale human impacts constituting a new geological epoch: the Anthropocene. Earth system resilience critically depends on the nonlinear interplay of positive and negative feedbacks of biophysical and increasingly also socio-economic processes. These include dynamics and interactions between the carbon cycle, the atmosphere, oceans, large-scale ecosystems, and the cryosphere, as well as the dynamics and perturbations associated with human activities.
With rising anthropogenic pressures, there is an increasing risk we might be hitting the ceiling of some of the self-regulating feedbacks of the Earth System, and cross tipping points which could trigger large-scale and partly irreversible impacts on the environment, and impact the livelihood of millions of people. Potential domino effects or tipping cascades could arise due to the interactions between these tipping elements and lead to a further decline of Earth resilience. At the same time, there is growing evidence supporting the potential of positive (social) tipping points that could propel rapid decarbonization and transformative change towards global sustainability.
In this session we invite contributions on all topics relating to tipping points in the Earth system, positive (social) tipping, as well as their interaction and domino effects. We are particularly interested in various methodological approaches, from Earth system modelling to conceptual modelling and data analysis of nonlinearities, tipping points and abrupt shifts in the Earth system.

Non-destructive testing (NDT) methods are employed in a variety of engineering and geosciences applications and their stand-alone use has been greatly investigated to date. New theoretical developments, technological advances and the progress achieved in surveying, data processing and interpretation have in fact led to a tremendous growth of the equipment reliability, allowing outstanding data quality and accuracy.
Nevertheless, the requirements of comprehensive site and material investigations may be complex and time-consuming, involving multiple expertise and multiple equipment. The challenge is to step forward and provide an effective integration between data outputs with different physical quantities, scale domains and resolutions. In this regard, enormous development opportunities relating to data fusion, integration and correlation between different NDT methods and theories are to be further investigated.
This Session primarily aims at disseminating contributions from state-of-the-art NDT methods and new numerical developments, promoting the integration of existing equipment and the development of new algorithms, surveying techniques, methods and prototypes for effective monitoring and diagnostics. NDT techniques of interest are related–but not limited to–the application of acoustic emission (AE) testing, electromagnetic testing (ET), ground penetrating radar (GPR), geoelectric methods (GM), laser testing methods (LM), magnetic flux leakage (MFL), microwave testing, magnetic particle testing (MT), neutron radiographic testing (NR), radiographic testing (RT), thermal/infrared testing (IRT), ultrasonic testing (UT), seismic methods (SM), vibration analysis (VA), visual and optical testing (VT/OT).
The Session will focus on the application of different NDT methods and theories and will be related –but not limited to– the following investigation areas:
- advanced data fusion;
- advanced interpretation methods;
- design and development of new surveying equipment and prototypes;
- real-time and remote assessment and monitoring methods for material and site inspection (real-life and virtual reality);
- comprehensive and inclusive information data systems for the investigation of survey sites and materials;
- numerical simulation and modelling of data outputs with different physical quantities, scale domains and resolutions;
- advances in NDT methods, numerical developments and applications (stand-alone use of existing and state-of-the-art NDTs).
Glacial Isostatic Adjustment (GIA) describes the dynamic response of the solid Earth to ice sheet glaciation/deglaciation, which affects the spatial and temporal sea level changes, and induces surface deformation, gravitational field variation and stress changes in the subsurface. The process is influenced by the ice sheet characteristics (e.g., extent, volume, grounding line) and solid Earth structure. With more observational data (e.g., relative sea-level data, GPS data, tide gauges, terrestrial and satellite gravimetry, glacially induced faults) are available/standardized, we can better investigate the interactions between the ice sheets, solid Earth and sea levels, and reveal the ice sheet and sea-level evolution histories and rheological properties of the Earth.
This session invites contributions discussing observations, analysis, and modelling of ice sheet dynamics, solid Earth response, and the resulting global, regional and local sea-level changes and land deformation, including paleo ice sheet and paleo sea-level investigations, geodetic measurements of crustal motion and gravitational change, GIA modelling with complex Earth models (e.g., 3D viscosity, non-linear rheologies) and coupled ice-sheet/Earth modelling, investigations on glacially triggered faulting as well as the Earth’s elastic response to present-day ice mass changes. We also welcome abstracts that address the future ice sheets/shelves evolution and sea-level projection as well as GIA effects on oil migration and nuclear waste repositories. Contributions related to both polar regions and previously glaciated regions are welcomed. This session is co-sponsored by the SCAR sub-committee INSTANT-EIS, Earth - Ice - Sea level, in view of instabilities and thresholds in Antarctica https://www.scar.org/science/instant/home/.
Recently, there have been significant breakthroughs in the use of fiber-optic sensing techniques to interrogate cables at high precision both on land and at sea as well as in boreholes and at the surface. Laser reflectometry using both fit-to-purpose and commercial fiber-optic cables have successfully detected a variety of signals including microseism, local and teleseismic earthquakes, volcanic events, ocean dynamics, etc. Other laser-based techniques can be used to monitor distributed strain, temperature, and even chemicals at a scale and to an extent previously unattainable with conventional geophysical methods.
We welcome any contributions to recent development in the fields of applications, instrumentation, and theoretical advances for geophysics with fiber-optic sensing techniques. These may include - but are not limited to - application of fiber-optic cables or sensors in seismology, geodesy, geophysics, natural hazards, oceanography, urban environment, geothermal application, etc. with an emphasis on laboratory studies, large-scale field tests, and modeling. We also encourage contributions on data analysis techniques, machine learning, data management, instruments performances and comparisons as well as new experimental field studies.
Hydroclimatic conditions and availability of water resources in space and time constitute important factors for maintaining adequate food supply, the quality of the environment, and the welfare of citizens and inhabitants, in the context of a post-pandemic sustainable growth and economic development. This session is designed to explore the impacts of hydroclimatic variability, climate change, and temporal and spatial availability of water resources on different factors, such as food production, population health, environment quality, and local ecosystem welfare.
We particularly welcome submissions on the following topics:
• Complex inter-linkages between hydroclimatic conditions, food production, and population health, including: extreme weather events, surface and subsurface water resources, surface temperatures, and their impacts on food security, livelihoods, and water- and food-borne illnesses in urban and rural environments.
• Quantitative assessment of surface-water and groundwater resources, and their contribution to agricultural system and ecosystem statuses.
• Spatiotemporal modeling of the availability of water resources, flooding, droughts, and climate change, in the context of water quality and usage for food production, agricultural irrigation, and health impacts over a wide range of spatiotemporal scales.
• Smart infrastructure for water usage, reduction of water losses, irrigation, environmental and ecological health monitoring, such as development of advanced sensors, remote sensing, data collection, and associated modeling approaches.
• Modelling tools for organizing integrated solutions for water supply, precision agriculture, ecosystem health monitoring, and characterization of environmental conditions.
• Water re-allocation and treatment for agricultural, environmental, and health related purposes.
• Impact assessment of water-related natural disasters, and anthropogenic forcing (e.g. inappropriate agricultural practices, and land usage) on the natural environment (e.g. health impacts from water and air, fragmentation of habitats, etc.)

Extreme hydro-meteorological events drive many hydrologic and geomorphic hazards, such as floods, landslides and debris flows, which pose a significant threat to modern societies on a global scale. The continuous increase of population and urban settlements in hazard-prone areas in combination with evidence of changes in extreme weather events lead to a continuous increase in the risk associated with weather-induced hazards. To improve resilience and to design more effective mitigation strategies, we need to better understand the aspects of vulnerability, risk, and triggers that are associated with these hazards.
This session aims at gathering contributions dealing with various hydro-meteorological hazards that address the aspects of vulnerability analysis, risk estimation, impact assessment, mitigation policies and communication strategies. Specifically, we aim to collect contributions from academia, the industry (e.g. insurance) and government agencies (e.g. civil protection) that will help identify the latest developments and ways forward for increasing the resilience of communities at local, regional and national scales, and proposals for improving the interaction between different entities and sciences.
Contributions focusing on, but not limited to, novel developments and findings on the following topics are particularly encouraged:
- Physical and social vulnerability analysis and impact assessment of hydro-meteorological hazards
- Advances in the estimation of socioeconomic risk from hydro-meteorological hazards
- Characteristics of weather and precipitation patterns leading to high-impact events
- Relationship between weather and precipitation patterns and socio-economic impacts
- Hazard mitigation procedures
- Strategies for increasing public awareness, preparedness, and self-protective response
- Impact-based forecast, warning systems, and rapid damage assessment.
- Insurance and reinsurance applications

Proper characterization of uncertainty remains a major research and operational challenge in Environmental Sciences, and is inherent to many aspects of modelling impacting model structure development; parameter estimation; an adequate representation of the data (inputs data and data used to evaluate the models); initial and boundary conditions; and hypothesis testing. To address this challenge, methods for a) uncertainty analysis (UA) that seek to identify, quantify and reduce the different sources of uncertainty, as well as propagating them through a system/model, and b) the closely-related methods for sensitivity analysis (SA) that evaluate the role and significance of uncertain factors (in the functioning of systems/models), have proved to be very helpful.
This session invites contributions that discuss advances, both in theory and/or application, in methods for SA/UA applicable to all Earth and Environmental Systems Models (EESMs), which embraces all areas of hydrology, such as classical hydrology, subsurface hydrology and soil science.
Topics of interest include (but are not limited to):
1) Novel methods for effective characterization of sensitivity and uncertainty
2) Analyses of over-parameterised models enabled by AI/ML techniques
3) Single- versus multi-criteria SA/UA
4) Novel approaches for parameter estimation, data inversion and data assimilation
5) Novel methods for spatial and temporal evaluation/analysis of models
6) The role of information and error on SA/UA (e.g., input/output data error, model structure error, parametric error, regionalization error in environments with no data etc.)
7) The role of SA in evaluating model consistency and reliability
8) Novel approaches and benchmarking efforts for parameter estimation
9) Improving the computational efficiency of SA/UA (efficient sampling, surrogate modelling, parallel computing, model pre-emption, model ensembles, etc.)
Research and innovation in exploration and mining of raw materials is increasingly focused on the prospect of developing completely new methods and technologies to find and exploit new mineral deposits within Europe. Amongst these technologies, robotisation and miniaturisation of exploration/production platforms (robotic autonomous explorers & miners) allow to reconsider “non-economical” deposits (abandoned, small, ultra-depth), extract them in a socially and environmentally responsible way, and produce useful metallurgical products which can be used further-on for manufacturing.
Underground operation of an autonomous or semi-autonomous underground platform is an extremely challenging problem where solution have to come from the close collaboration of robotic engineers, mining engineers, mineralogists, geochemists, geophysicians and structuralists to solve challenges as diverse as locomotion in water or slurries, localization and mapping in relationship with an orebody, automated extraction planning, optimization of extraction tools, and real-time selective mineralogy.
Contributions from geologists, geophysicists, mining engineers, robotic engineers, software developers are welcome.
Publishing your research in a peer reviewed journal is essential for a career in research. All EGU-affiliated journals are fully open access which is great, but the unique open discussion and transparent peer review process can be daunting for first time submitters and early career scientists. This short course will cover all you need to know about the publication process from start to end for EGU journals, and give you a chance to ask the editors some questions. This includes: what the editor looks for in your submitted paper, how to deal with corrections or rejections, and how best to communicate with your reviewers and editors for a smooth transition from submission to publication. Ample time will be reserved for open discussion for the audience to ask questions to the editors, and for the editors to suggest ‘top tips’ for successful publication. This course is aimed at early-career researchers who are about to step into the publication process, and those who are yet to publish in EGU journals. Similarly, this course will be of interest to those looking to get involved in the peer-review process through reviewing and editing. This short course is part of the “Meet the EGU Journal Editors” webinar series that was held prior to the EGU General Assembly 2022.

Observations and measurements of geophysical systems and dynamical phenomena are obtained as time series or spatio-temporal data whose dynamics usually manifests a nonlinear multiscale (in terms of time and space) behavior. During the past decades, nonlinear approaches in geosciences have rapidly developed to gain novel insights on weather and climate dynamics, fluid dynamics, on turbulence and stochastic behaviors, on the development of chaos in dynamical systems, and on concepts of networks, nowadays frequently employed in geosciences.
In this short course, we will offer a broad overview of the development and application of nonlinear concepts across the geosciences in terms of recent successful applications from various fields, ranging from climate to near-Earth space physics. The focus will be on a comparison between different methods to investigate various aspects of both known and unknown physical processes, moving from past accomplishments to future challenges.

The climate system as a whole can be viewed as a highly complex thermal/heat engine, in which numerous processes continuously interact to transform heat into work and vice-versa. As any physical system, the climate system obeys the basic laws of thermodynamics, and we may therefore expect the tools of non-equilibrium thermodynamics to be particularly useful in describing and synthesising its properties. The main aim of this short course will be twofold. Part 1 will provide an advanced introduction to the fundamentals of equilibrium and non-equilibrium thermodynamics, irreversible processes and energetics of multicomponent stratified fluids. Part 2 will illustrate the usefulness of this viewpoint to summarize the main features of the climate system in terms of thermodynamic cycles, as well as a diagnostic tool to constrain the behavior of climate models. Although the aim is for this to be a self-contained module, some basic knowledge of the subject would be beneficial to the participants.
- The first part, chaired by Remi Tailleux, will provide an advanced introduction on the fundamentals of equilibrium and non-equilibrium thermodynamics, irreversible processes and energetics.
- The second part, chaired by Valerio Lembo and Gabriele Messori, will illustrate some applications of thermodynamics to the study of the climate system and its general circulation.

The short course will be structured as such: - Part 1 (45 mins): theoretical background, by Remi Tailleux;
- Short break (5 mins);
- Part 2 (15 mins): diagnosing thermodynamics in climate models, by Valerio Lembo;
- Part 3 (10 mins): dynamics and heat transports in the atmosphere, by Gabriele Messori;
The climate is highly variable over wide ranges of scale in both space and time so that the amplitude of changes systematically depends on the scale of observations. As a consequence, climate variations recorded in time series or spatial distributions, which are produced through modelling or empirical analyses are inextricably linked to their space-time scales and is a significant part of the uncertainties in the proxy approaches. Rather than treating the variability as a limitation to our knowledge, as a distraction from mechanistic explanations and theories, in this course the variability is treated as an important, fundamental aspect of the climate dynamics that must be understood and modelled in its own right. Long considered as no more than an uninteresting spectral “background”, modern data shows that in fact it contains most of the variance.
We review techniques that make it possible to systematically analyse and model the variability of instrumental and proxy data, the inferred climate variables and the outputs of GCM’s. These analyses enable us to cover wide ranges of scale in both space and in time - and jointly in space-time - without trivializing the links between the measurements, proxies and the state variables (temperature, precipitation etc.). They promise to systematically allow us to compare model outputs with data, to understand the climate processes from small to large and from fast to slow. Specific tools that will be covered include spectral analysis, scaling fluctuation analysis, wavelets, fractals, multifractals, and stochastic modeling; we discuss corresponding software. We also include new developments in the Fractional Energy Balance Equation approach that combines energy and scale symmetries.

Within this course, the attendees are taught how to identify possible cyclicities in paleoclimate data (e.g., sediments, speleothems) or any other geological record. We will start from the basics of which data can be analysed, go over power spectra, and discuss the application of filters and Wavelet Analysis. We will discuss the advantages and disadvantages of different methods, and give some examples from Earth Sciences to highlight common pitfalls. The aim of this course is to give a brief overview of the most common techniques and give participants the insight to prepare and analyse their data themselves. A variety of computational platforms are available for time-series analysis. In this course, we will introduce different tools and techniques by making use of the programming language R.

This session will focus on variability in the ocean and its role in the wider climate system using both observations and models. Areas to be considered will include both ocean heat uptake and circulation variability as well as exploring the use of sustained ocean observing efforts and models to make progress in understanding the ocean’s role in the climate system. More than 90% of the excess heat in the climate system has been stored in the ocean, which mitigates the rate of surface warming. Better understanding of ocean ventilation mechanisms, as well as the uptake, transport, and storage of oceanic heat are therefore essential for reducing the uncertainties on global warming projections. Circulation variability and connectivity, particularly from the South Atlantic to the North Atlantic and Arctic Ocean, are also of interest as well as how they are driven by local-, large- or global-scale processes or teleconnections. Sustained observations at sea are being made within a wide variety of programmes and are leading to significant advances in our ability to understand and model climate. Thus, this session will also explore ongoing and planned sustained ocean observing efforts and illuminate their roles in improving understanding of the ocean’s role in the climate system. For example, air-sea flux moorings are being maintained at select sites to assess models and air-sea flux fields. Deep temperature and salinity measurements are being made at time series moorings and will be made by deep Argo floats. Significant advances are also being made using Argo floats for biogeochemistry and carbon measurements. Such observations provide the means to develop linkages between sustained ocean observing and climate modelling. In conclusion, the session will consider key aspects of ocean variability and its climate relevance, as well as encouraging the use of observations and models to enhance understanding of these areas.

The ocean surface mixed layer mediates the transfer of heat, freshwater, momentum and trace gases between atmosphere, sea ice and ocean, thus playing a central role in the dynamics of our climate. This session will focus on the surface mixed layer globally, from the coastal ocean to the deep ocean. We will review recent progress in understanding the key dynamical and biogeochemical processes taking place in the mixed layer: surface waves, Langmuir circulations and turbulence, shear-induced mixing, internal waves, coherent structures, fronts, frontal instabilities, entrainment and detrainment at the mixed layer base, convection, restratification, dynamics of the euphotic layer, carbon and nutrient cycling, etc. The improvement of the representation of surface mixed layer processes in numerical models is a complex and pressing issue: this session will bring together new advances in the representation of mixed layer processes in high resolution numerical models, as well as evaluation of mixed layer properties in climate models using most recent observational datasets. The coupling of the ocean and atmospheric boundary layers as well as the special processes occurring under sea ice and in the marginal sea ice zone will be given special consideration. This session welcomes all contributions related to the study of the oceanic mixed layer independent of the time- and space scales considered. This includes small scale process studies, short-term forecasting of the mixed layer characteristics for operational needs, studies on the variability of the mixed layer from sub-seasonal to multi annual time scales and mixed layer response to external forcing. The use of multiple approaches (coupled numerical modeling, reanalyses, observations) is encouraged.

Ocean ventilation is a process by which water properties imprinted by the atmosphere onto the upper ocean, such as oxygen, carbon dioxide and trace gases, are transported into the ocean interior. In mediating the exchange between the atmosphere and the ocean, ventilation plays an important role in both climate variability and biogeochemical cycles. This is manifested, for example, through the supply of oxygen to the ocean interior, transport and sequestration of nutrients, and the uptake and storage of anthropogenic carbon and heat in the ocean interior. Increased stratification - caused by the warming on the upper ocean under climate change - could lead to a reduction of ocean ventilation over the coming decades. However, the mechanism by which the changes in ocean ventilation will emerge, and their consequences for climate feedback, biogeochemical processes, and ocean ecosystems are not well known.
Developing our understanding of ocean ventilation is inhibited by the wide range of spatial scales inherent in the process, from small-scale mixing to basin scale. Robust projection of future change requires deeper insight into the processes driving ventilation, the spatial and temporal variability of ventilation, and the consequences and impacts of ventilation changes.
We invite contributions that advance understanding on the broad topic of ocean ventilation, its potential to change in a warming climate, and the consequences therein. We seek contributions that investigate both the physical processes involved in ocean ventilation — from small-scale mixing, to mesoscale stirring, to basin scale subduction — as well as the consequences for biogeochemical cycles and marine ecosystems. We welcome contributions from process-oriented studies as well as those that assess and quantify variability and projected changes, and welcome studies making use of observations, theory and/or numerical model.
The session is expected to be in a hybrid format, partly taking place in Vienna in a traditional format, and partly online.
Theoretical and model studies show that the ocean is a chaotic system which spontaneously generates a strong, multi-scale intrinsic chaotic variability: uncertainties in ocean model initial states may grow and strongly affect the simulated variability up to multi-decadal and basin scales, with or without coupling to the atmosphere. In addition, ocean simulations require both the use of subgrid-scale parameterizations that crudely mimic unresolved processes, and the calibration of the parameters associated with these parameterizations. In this context of multiple uncertainties, oceanographers are increasingly adopting ensemble simulation strategies, probabilistic analysis methods, and developing stochastic parameterizations for modeling and understanding ocean variability.
Presentations are solicited about the conception and analysis of ocean ensemble simulations, the characterization of ocean model uncertainties, and the development of stochastic parameterizations for ocean models. The session will also cover the dynamics and structure of chaotic ocean variability, its relationship with atmospheric variability, and the use of dynamical system or information theories for the investigation of oceanic variability. We welcome as well studies about the propagation of chaotic ocean variability towards other components of the climate system, about its consequences regarding ocean predictability, operational forecasts, detection and attribution of climate signals, climate simulations and projections.

The rapid decline of the Arctic sea ice in the last decade is a dramatic indicator of climate change. The Arctic sea ice cover is now thinner, weaker and drifts faster. Freak heatwaves are common. On land, the permafrost is dramatically thawing, glaciers are disappearing, and forest fires are raging. The ocean is also changing: the volume of freshwater stored in the Arctic has increased as have the inputs of coastal runoff from Siberia and Greenland and the exchanges with the Atlantic and Pacific Oceans. As the global surface temperature rises, the Arctic Ocean is speculated to become seasonally ice-free by the mid 21st century, which prompts us to revisit our perceptions of the Arctic system as a whole. What could the Arctic Ocean look like in the future? How are the present changes in the Arctic going to affect and be affected by the lower latitudes? What aspects of the changing Arctic should observational, remote sensing and modelling programmes address in priority?
In this session, we invite contributions from a variety of studies on the recent past, present and future Arctic. We encourage submissions examining interactions between the ocean, atmosphere and sea ice, on emerging mechanisms and feedbacks in the Arctic and on how the Arctic influences the global ocean. Submissions taking a cross-disciplinary, system approach and focussing on emerging cryospheric, oceanic and biogeochemical processes and their links with land are particularly welcome.
The session supports the actions of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030) towards addressing challenges for sustainable development in the Arctic and its diverse regions. We aim to promote discussions on the future plans for Arctic Ocean modelling and measurement strategies, and encourages submissions on the results from IPCC CMIP and the recent observational programs, such as the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC). This session is cosponsored by the CLIVAR /CliC Northern Ocean Regional Panel (NORP) that aims to facilitate progress and identify scientific opportunities in (sub)Arctic ocean-sea-ice-atmosphere research.
Drs Karen Assmann and Wilken-Jon von Appen are the solicited speakers for the session. Karen Assmann will be presenting on physical and ecological implications of Arctic Atlantification. Wilken-Jon von Appen will be talking about eddies in the Arctic Ocean.

The North Atlantic exhibits a high level of natural variability from interannual to centennial time scales, making it difficult to extract trends from observational time series. Climate models, however, predict major changes in this region, which in turn will influence sea level and climate, especially in western Europe and North America. In the last years, several observational projects have been focused on the Atlantic circulation changes, for instance ACSIS, RACE, RAPID, OSNAP, and OVIDE. Another important issue is the interaction between the atmosphere and the ocean as well as the cryosphere with the ocean, and how this affects the climate.
We welcome contributions from observers and modelers on the following topics:
-- climate relevant processes in the North Atlantic region in the atmosphere, ocean, and cryosphere
-- response of the atmosphere to changes in the North Atlantic
-- atmosphere - ocean coupling in the North Atlantic realm on time scales from years to centuries (observations, theory and coupled GCMs)
-- interpretation of observed variability in the atmosphere and the ocean in the North Atlantic sector

Observations and model simulations illustrate significant ocean variability and associated air-sea interactions in the tropical Atlantic basin from daily-to-decadal time scales. This session is devoted to the understanding of ocean dynamics in the tropical and subtropical Atlantic Ocean, its interaction with the overlying atmosphere from the equator to the mid-latitudes and its climate impacts on adjacent to remote areas. Relevant processes in the ocean include upper and deep ocean circulation, eddies, tropical instability waves, warm pools, cold tongues and eastern boundary upwellings. We are interested in air-sea interactions related to both the seasonal cycle and the development of modes of variability from local to basin scale (e.g. the Meridional Mode, the Atlantic Niño, and the Benguela Niño). We welcome studies on wind variations related to the development of these modes, as well as studies on high-frequency events, such as marine heat waves, the Madden-Julian Oscillation, tropical cyclones and convective systems. Furthermore, we seek studies on climate change in the region, and also of the climatic impacts of change and variability on marine ecosystems. Finally, we are also interested in contributions examining the causes and impacts of systematic model errors in simulating the local to regional Atlantic climate. Studies based on direct observations, reanalysis, reconstructions as well as model simulations are welcome.

The Indian Ocean is unique among the other tropical ocean basins due to the seasonal reversal of monsoon winds and concurrent ocean currents, lack of steady easterlies that result in a relatively deep thermocline along the equator, low-latitude connection to the neighboring Pacific and a lack of northward heat export due to the Asian continent. These characteristics shape the Indian Ocean’s air-sea interactions, variability, as well as its impacts and predictability in tropical and extratropical regions on (intra)seasonal, interannual, and decadal timescales. They also make the basin particularly vulnerable to anthropogenic climate change, as well as related extreme weather and climate events, and their impacts for surrounding regions, which are home to a third of the global population. Advances have recently been made in our understanding of the Indian Ocean’s circulation, interactions with adjacent ocean basins, and its role in regional and global climate. Nonetheless, significant gaps remain in understanding, observing, modeling, and predicting Indian Ocean variability and change across a range of timescales.
This session invites contributions based on observations, modelling, theory, and palaeo proxy reconstructions in the Indian Ocean that focus on recent observed and projected changes in Indian Ocean physical and biogeochemical properties and their impacts on ecological processes, diversity in Indian Ocean modes of variability (e.g., Indian Ocean Dipole, Indian Ocean Basin Mode, Madden-Julian Oscillation) and their impact on predictions, interactions and exchanges between the Indian Ocean and other ocean basins, as well as links between Indian Ocean variability and monsoon systems across a range of timescales. In particular, we encourage submissions on weather and climate extremes in the Indian Ocean, including marine heatwaves and their ecological impacts. We also welcome contributions that address research on the Indian Ocean grand challenges highlighted in the recent IndOOS Decadal Review, and as formulated by the Climate and Ocean: Variability, Predictability, and Change (CLIVAR), the Sustained Indian Ocean Biogeochemistry and Ecosystem Research (SIBER), the International Indian Ocean Expedition 2 (IIOE-2), findings informed by the Coupled Model Intercomparison Project version 6 (CMIP6) on past, present and future variability and change in the Indian Ocean climate system, and contributions making use of novel methodologies such as machine learning.

The Southern Ocean around the latitudes of the Antarctic Circumpolar Current is vital to our understanding of the climate system. It is a key region for vertical and lateral exchanges of heat, carbon, and nutrients, with significant past and potential future global climate implications. The role of the Southern Ocean as a dominant player in heat and carbon exchanges in present and future climate conditions remains uncertain. Indeed, the lack of observations of this system and its inherent sensitivity to small-scale physical processes, not fully represented in current Earth system models, result in large climate projection uncertainties. To address these knowledge gaps, the Southern Ocean has been the subject of recent observational, theoretical, and numerical modelling investigations. These efforts are providing deeper insight into the three-dimensional patterns of Southern Ocean change on sub-annual, multi-decadal and millennial timescales. In this session, we will discuss the current state of knowledge and novel findings concerning the role of the Southern Ocean in past, present, and future climates. These include (but are not limited to) small-scale physics and mixing, water mass transformation, gyre-scale processes, nutrient and carbon cycling, ocean productivity, climate-carbon feedbacks, and ocean-ice-atmosphere interactions. We will also discuss how changes in Southern Ocean heat and carbon transport affect lower latitudes and global climate more generally.
The interaction between the ocean and the cryosphere in the Southern Ocean has become a major focus in climate research. Antarctic climate change has captured public attention, which has spawned a number of research questions, such as: Is Antarctic sea ice becoming more vulnerable in a changing climate? Where and when will melting of ice shelves by warm ocean waters yield a tipping point in Antarctic climate? What role do ice-related processes play in nutrient upwelling on the continental shelf and in triggering carbon export to deep waters? Recent advances in observational technology, data coverage, and modeling provide scientists with a better understanding of the mechanisms involving ice-ocean interactions in the far South. Processes on the Antarctic continental shelf have been identified as missing links between the cryosphere, the global atmosphere and the deep open ocean that need to be captured in large-scale and global model simulations.
This session calls for studies on physical and biogeochemical interactions between ice shelves, sea ice and the ocean. The ice-covered Southern Ocean and its role in the greater Antarctic climate system are of major interest. This includes work on all scales, from local to basin-scale to circumpolar. Studies based on in-situ observations and remote sensing as well as regional to global models are welcome. We particularly invite cross-disciplinary topics involving physical and biological oceanography, glaciology or biogeochemistry.

The Open Session on atmosphere, land and ocean monitoring aims at presenting highlights of recent results obtained through observations and modelling as well as relevant reviews in these fields.
We shall connect with Earth Observations programmes at ESA, EU and worldwide, using new satellites and oberving platforms, as well as new techniques for distributing, merging and analysing EO data using AI.
The session is intended as an open forum for interdisciplinary discussion between representatives of different fields. Thus, we welcome especially overarching presentations which may be interesting to a wider community.
Observations are one major link to get an overall picture of processes within the Earth environment during measurement campaigns. This includes application to derive atmospheric parameters, surface properties of vegetation, soil and minerals and dissolved or suspended matter in inland water and the ocean. Ground based systems and data sets from ships, aircraft and satellites are key information sources to complement the overall view. All of these systems have their pros and cons, but a comprehensive view of the observed system is generally best obtained by means of a combination of all of them.
The validation of operational satellite systems and applications is a topic that has come increasingly into focus with the European Copernicus program in recent years. The development of smaller state-of-the-art instruments, the combination of more and more complex sets of instruments simultaneously on one platform, with improved accuracy and high data acquisition speed together with high accuracy navigation and inertial measurements enables more complex campaign strategies even on smaller aircraft or unmanned aerial vehicles (UAV).
This session will bring together a multidisciplinary research community to present:
• Atmosphere-land-ocean (or inland water) system modelling and validation
• new instruments (Lidar, etc), platforms (UAV etc.), setups and use in multidisciplinary approaches
• Larger scale in-situ and remote sensing observation networks from various platforms (ground based, airborne, ship-borne, satellite)
• recent field campaigns and their outcomes
• (multi-) aircraft campaigns
• satellite calibration/validation campaigns
• sophisticated instrument setups and observations
• advanced instrument developments
• UAV applications

The largest single source of uncertainty in projections of future global sea level is associated with the mass balance of the Antarctic Ice Sheet (AIS). In the short-term, it cannot be stated with certainty whether the mass balance of the AIS is positive or negative; in the long-term, the possibility exists that melting of the coastal shelves around Antarctica will lead to an irreversible commitment to ongoing sea level rise. Observational and paleoclimate studies can help to reduce this uncertainty, constraining the parameterizations of physical processes within ice sheet models and allowing for improved projections of future global sea level rise. This session welcomes presentations covering all aspects of observation, paleoclimate reconstruction and modeling of the AIS. Presentations that focus on the mass balance of the AIS and its contribution towards changes in global sea level are particularly encouraged.
In recent decades, the climate in the polar regions has undergone dramatic changes. Quantifying the individual contributions of Earth system components (cryosphere, ocean, atmosphere, and land) to the observed changes is challenging due to feedback between the components. Examples include (but are not limited to) ice shelf-ocean interactions (through basal melting and cavity geometry evolution) and elevation feedbacks (through surface mass balance). Hence, studies based on individual components of the Earth System have limited capacity to represent all relevant processes. This session aims to provide a platform for sharing coupled modelling experiences incorporating the cryosphere in the polar regions.
Before obtaining scientific outcomes, design decisions must be made in the development of coupled models. Adopting existing coupling technologies or implementing new, concurrent or sequential parallelism, bringing component source codes together or maintaining independence, choosing the level of temporal synchronicity between components operating on different timescales, are all examples of choices to be made.
We solicit both technical and scientific contributions from modelling studies in which feedback and emergent properties between the cryosphere and other Earth System components in polar regions are investigated, better understood, and possibly even quantified. In addition to application of coupled modelling to real world domains, contributions are also invited from idealised studies and intercomparisons, such as the Marine Ice Sheet-Ocean Intercomparison Project (MISOMIP).
Machine learning, artificial intelligence and big data approaches have recently emerged as key tools in understanding the cryosphere. These approaches are being increasingly applied to answer long standing questions in cryospheric science, including those relating to remote sensing, forecasting, and improving process understanding across Antarctic, Arctic and Alpine regions. In doing so, data science and AI techniques are being used to gain insight into system complexity, analyse data on unprecedented temporal and spatial scales, and explore much wider parameter spaces than were previously possible.
In this session we invite submissions that utilise data science and/or AI techniques that address research questions relating to glaciology, sea ice, permafrost and/or polar climate science. Approaches used may include (but are not limited to) machine learning, artificial intelligence, big data processing/automation techniques, advanced statistics, and innovative software/computing solutions. These could be applied to any (or combinations) of data sources including remote sensing, numerical model output and field/lab observations. We particularly invite contributions that apply techniques and approaches that reveal new insights into cryospheric research problems that would not otherwise be achievable using traditional methods, and those that discuss how or if approaches can be applied or adapted to other areas of cryospheric science. Given the rapid development of this field by a diverse group of international researchers, we convene this session to help foster future collaboration amongst session contributors, attendees, and international stakeholders and help address the most challenging questions in cryospheric science.

Ice sheets play an active role in the climate system by amplifying, pacing, and potentially driving global climate change over a wide range of time scales. The impact of interactions between ice sheets and climate include changes in atmospheric and ocean temperatures and circulation, global biogeochemical cycles, the global hydrological cycle, vegetation, sea level, and land-surface albedo, which in turn cause additional feedbacks in the climate system. This session will present data and modelling results that examine ice sheet interactions with other components of the climate system over several time scales. Among other topics, issues to be addressed in this session include ice sheet-climate interactions from glacial-interglacial to millennial and centennial time scales, the role of ice sheets in Cenozoic global cooling and the mid-Pleistocene transition, reconstructions of past ice sheets and sea level, the current and future evolution of the ice sheets, and the role of ice sheets in abrupt climate change.
Ice shelves and tidewater glaciers are sensitive elements of the climate system. Sandwiched between atmosphere and ocean, they are vulnerable to changes in either. The recent disintegration of ice shelves such as Larsen B and Wilkins on the Antarctic Peninsula, current thinning of the ice shelves in the Amundsen Sea sector of West Antarctica, and the recent accelerations of many of Greenland's tidewater glaciers provide evidence of the rapidity with which those systems can respond. Changes in marine-terminating outlets appear to be intimately linked with acceleration and thinning of the ice sheets inland of the grounding line, with immediate consequences for global sea level. Studies of the dynamics and structure of the ice sheets' marine termini and their interactions with atmosphere and ocean are the key to improving our understanding of their response to climate forcing and of their buttressing role for ice streams. The main themes of this session are the dynamics of ice shelves and tidewater glaciers and their interaction with the ocean, atmosphere and the inland ice, including grounding line dynamics. The session includes studies on related processes such as calving, ice fracture, rifting and mass balance, as well as theoretical descriptions of mechanical and thermodynamic processes. We seek contributions both from numerical modelling of ice shelves and tidewater glaciers, including their oceanic and atmospheric environments, and from observational studies of those systems, including glaciological and oceanographic field measurements, as well as remote sensing and laboratory studies.

One of the big challenges in Earth system science consists in providing reliable climate predictions on sub-seasonal, seasonal, decadal and longer timescales. The resulting data have the potential to be translated into climate information leading to a better assessment of global and regional climate-related risks.
The latest developments and progress in climate forecasting on subseasonal-to-decadal and longer timescales will be discussed and evaluated. This will include presentations and discussions of predictions for the different time horizons from dynamical ensemble and statistical/empirical forecast systems, as well as the aspects required for their application: forecast quality assessment, multi-model combination, bias adjustment, downscaling, exploration of artificial-intelligence methods, etc.
Following the new WCRP strategic plan for 2019-2029, prediction enhancements are solicited from contributions embracing climate forecasting from an Earth system science perspective. This includes the study of coupled processes between atmosphere, land, ocean, and sea-ice components, as well as the impacts of coupling and feedbacks in physical, chemical, biological, and human dimensions. Contributions are also sought on initialization methods that optimally use observations from different Earth system components, on assessing and mitigating the impacts of model errors on skill, and on ensemble methods.
We also encourage contributions on the use of climate predictions for climate impact assessment, demonstrations of end-user value for climate risk applications and climate-change adaptation and the development of early warning systems.
A special focus will be put on the use of operational climate predictions (C3S, NMME, S2S), results from the CMIP5-CMIP6 decadal prediction experiments, and climate-prediction research and application projects.
An increasingly important aspect for climate forecast's applications is the use of most appropriate downscaling methods, based on dynamical or statistical approaches or their combination, that are needed to generate time series and fields with an appropriate spatial or temporal resolution. This is extensively considered in the session, which therefore brings together scientists from all geoscientific disciplines working on the prediction and application problems.

To address societal concerns over rising sea level and extreme events, understanding the contributions behind these changes is key to predict potential impacts of sea level change on coastal communities and global economy, and is recognized as one of the Grand Challenges of our time by the World Climate Research Programme (WCRP). To continue this discussion, we welcome contributions from the international sea level community that improve our knowledge of the past and present changes in global and regional sea level, extreme events, and flooding, and produce improved predictions of their future changes.
We welcome studies on various drivers of sea level change and linkages between variability in sea level, heat and freshwater content, ocean dynamics, land subsidence from natural versus anthropogenic influences, and mass exchange between the land and the ocean associated with ice sheet and glacier mass loss and changes in the terrestrial water storage. Studies focusing on future sea level changes are also encouraged, as well as those discussing potential short-, medium-, and long-term impacts on coastal and deltaic environments, as well as the global oceans.

ENSO and its interactions with other tropical basins are the dominant source of interannual climate variability in the tropics and across the globe. Understanding the dynamics, predictability, and impacts of ENSO and tropical basins interactions, and anticipating their future changes are thus of vital importance for society. This session invites contributions regarding all aspects of ENSO and tropical basins interactions, including: dynamics, multi-scale interactions; low frequency, decadal and paleo variability; theoretical approaches; ENSO diversity; global teleconnections; impacts on climate, society and ecosystems; seasonal forecasting and climate change projections of ENSO and its tropical basins interactions. Studies aimed at evaluating and improving model simulations of ENSO, the tropical mean state and the tropical basins interactions basin are especially welcomed.

This session aims to place recently observed climate change in a long-term perspective by highlighting the importance of paleoclimate research spanning the past 2000 years. We invite presentations that provide insights into past climate variability, over decadal to millennial timescales, from different paleoclimate archives (ice cores, marine sediments, terrestrial records, historical archives and more). In particular, we are focussing on quantitative temperature and hydroclimate reconstructions, and reconstructions of large-scale modes of climate variability from local to global scales. This session also encourages presentations on the attribution of past climate variability to external drivers or internal climate processes, data syntheses, model-data comparison exercises, proxy system modelling, and novel approaches to producing multi-proxy climate field reconstructions.

Predictions of climate from seasonal to decadal timescales and their applications are discussed in this session. With a time horizon from a few months up to thirty years, such predictions are of major importance to society, and improving them presents an interesting scientific challenge. This session aims to embrace advances in our understanding of the origins of seasonal to decadal predictability, as well as in improving the respective forecast skill and making the most of this information by developing and evaluating new applications and climate services.
The session covers dynamical as well as statistical predictions (including machine learning methods) and their combination. It investigates predictions of various climate phenomena, including extremes, from global to regional scales, and from seasonal to multi-decadal timescales ("seamless predictions"). Physical processes relevant to long-term predictability sources (e.g. ocean, cryosphere, or land) as well as predicting large-scale atmospheric circulation anomalies associated to teleconnections are discussed, as are observational and emergent constraints on climate variability and predictability. Also, the time-dependence of the predictive skill, or windows of opportunity (hindcast period), are investigated. Analysis of predictions in a multi-model framework, and ensemble forecast initialization and generation, including innovative ensemble approaches to minimize initialization shocks, are another focus of the session. The session pays particular attention to innovative methods of quality assessment and verification of climate predictions, including extreme-weather frequencies, post-processing of climate hindcasts and forecasts, and quantification and interpretation of model uncertainty. We particularly invite contributions presenting the use of seasonal-to-decadal predictions for risk assessment, adaptation and further applications.

In 2015, the UN Sustainable Development Goals and the Paris Agreement on climate recognized the deteriorating resilience of the Earth system, with planetary-scale human impacts constituting a new geological epoch: the Anthropocene. Earth system resilience critically depends on the nonlinear interplay of positive and negative feedbacks of biophysical and increasingly also socio-economic processes. These include dynamics and interactions between the carbon cycle, the atmosphere, oceans, large-scale ecosystems, and the cryosphere, as well as the dynamics and perturbations associated with human activities.
With rising anthropogenic pressures, there is an increasing risk we might be hitting the ceiling of some of the self-regulating feedbacks of the Earth System, and cross tipping points which could trigger large-scale and partly irreversible impacts on the environment, and impact the livelihood of millions of people. Potential domino effects or tipping cascades could arise due to the interactions between these tipping elements and lead to a further decline of Earth resilience. At the same time, there is growing evidence supporting the potential of positive (social) tipping points that could propel rapid decarbonization and transformative change towards global sustainability.
In this session we invite contributions on all topics relating to tipping points in the Earth system, positive (social) tipping, as well as their interaction and domino effects. We are particularly interested in various methodological approaches, from Earth system modelling to conceptual modelling and data analysis of nonlinearities, tipping points and abrupt shifts in the Earth system.

An increasing number of single model large ensemble simulations from Global Climate Models (GCM), Earth System Models (ESM), or Regional Climate Models (RCM) have been generated over recent years, to investigate internal variability and forced changes of the climate system — and to aid the interpretation of the observational record by providing a range of historical climate trajectories that could have been. The increased availability of large ensembles also enables new and inter-disciplinary applications beyond large-scale climate dynamics.
This session invites studies using large GCM, ESM, or RCM ensembles looking at the following topics: 1) Reinterpretation of the observed record in light of internal variability; 2) forced changes in internal variability; 3) development of new approaches to attribute and study observed events or trends; 4) impacts of natural climate variability; 5) assessment of extreme and compound event occurrence; 6) combining single model large ensembles with CMIP archives for robust decision making; 7) large ensembles as testbeds for method development.
We welcome research across all components of the Earth system. Examples include topics ranging from climate dynamics, hydrology and biogeochemistry to research on the role of internal variability in impact studies, focused for example on agriculture, air pollution or energy generation and consumption. We particularly invite studies that apply novel methods or cross-disciplinary approaches to leverage the potential of large ensembles.

Modelling past climate states, and the transient evolution of Earth’s climate remains challenging. Time periods such as the Paleocene, Eocene, Pliocene, the Last Interglacial, the Last Glacial Maximum or the mid-Holocene span across a vast range of climate conditions. At times, these lie far outside the bounds of the historical period that most models are designed and tuned to reproduce. However, our ability to predict future climate conditions and potential pathways to them is dependent on our models' abilities to reproduce just such phenomena. Thus, our climatic and environmental history is ideally suited to thoroughly test and evaluate models against data, so they may be better able to simulate the present and make future climate projections.
We invite papers on palaeoclimate-specific model development, model simulations and model-data comparison studies. Simulations may be targeted to address specific questions or follow specified protocols (as in the Paleoclimate Modelling Intercomparison Project – PMIP or the Deep Time Model Intercomparison Project – DeepMIP). They may include anything between time-slice equilibrium experiments to long transient climate simulations (e.g. transient simulations covering the entire glacial cycle as per the goal of the PalMod project) with timescales of processes ranging from synoptic scales to glacial cycles and beyond. Comparisons may include past, historical as well as future simulations and focus on comparisons of mean states, gradients, circulation or modes of variability using reconstructions of temperature, precipitation, vegetation or tracer species (e.g. δ18O, δD or Pa/Th).
Evaluations of results from the latest phase of PMIP4-CMIP6 are particularly encouraged. However, we also solicit comparisons of different models (comprehensive GCMs, isotope-enabled models, EMICs and/or conceptual models) between different periods, or between models and data, including an analysis of the underlying mechanisms as well as contributions introducing novel model or experimental setups.

The dynamics of the Earth system and its components is highly nonlinear. In particular, several subsystems have been suggested to react abruptly at critical levels of anthropogenic forcing. Well-known examples of such Tipping Elements include the Atlantic Meridional Overturning Circulation, the polar ice sheets and sea ice, tropical and boreal forests, as well as the Asian monsoon systems. Interactions between the different Tipping Elements may either have stabilizing or destabilizing effects on the other subsystems, potentially leading to cascades of abrupt transitions. The critical forcing levels at which abrupt transitions occur have recently been associated with Tipping Points.
It is paramount to determine the critical forcing levels (and the associated uncertainties) beyond which the systems in question will abruptly change their state, with potentially devastating climatic, ecological, and societal impacts. For this purpose, we need to substantially enhance our understanding of the dynamics of the Tipping Elements and their interactions, on the basis of paleoclimatic evidence, present-day observations, and models spanning the entire hierarchy of complexity. Moreover, to be able to mitigate - or prepare for - potential future transitions, early warning signals have to be identified and monitored in both observations and models.
This multidisciplinary session invites contributions that address Tipping Points in the Earth system from the different perspectives of all relevant disciplines, including
- the mathematical theory of abrupt transitions in (random) dynamical systems,
- paleoclimatic studies of past abrupt transitions,
- data-driven and process-based modelling of past and future transitions,
- early-warning signals
- the implications of abrupt transitions for Climate sensitivity and response,
- ecological and societal impacts, as well as
- decision theory in the presence of uncertain Tipping Point estimates

Analysis of the energy transfers between and within climate components has been at the core of many step changes in the understanding of the climate system. Large-scale atmospheric circulation, hydrological cycle and heat/moisture transports are tightly intertwined through radiative and heat energy absorption and transports that are sensitive to multiple forcings and feedbacks. Cross-equatorial energy exchanges by the ocean and atmosphere couple Hadley Circulation and Atlantic Overturning circulation, modulating the location and intensity of the ITCZ and the amount of precipitation in monsoon regions. In the extra-tropics, Rossby waves affect the distribution of precipitation and eddy activity, shaping the meridional heat transport from the low latitudes towards the Poles through intermittent events of persistent and co-located blockings and the occurrence of extreme heat waves or cold outbreaks. In the ocean, understanding of energy transfers from large-scale circulation to the internal wave field, through mesoscale and submesoscale eddies, is the basis for the development of new parameterizations and significant modelling advances.
We invite submissions addressing the interplay between Earth’s energy exchanges and the general circulation using modeling, theory, and observations. We encourage contributions on the forced response and natural variability of the general circulation, understanding present-day climate and past and future changes, and impacts of global features and change on regional climate.

Arctic sea ice and high latitude atmosphere and oceans have experienced significant changes over the modern observational era. The polar climate is crucial for the Earth’s energy and water budget, and its variability and change have direct socio-economic and ecological impacts. Thus, understanding high-latitude variability and improving predictions of high latitude climate is highly important for society. Long-term variability in ocean and sea ice are the largest sources for predictability in high latitudes. Dynamical model predictions are not yet in the position to provide us with highly accurate predictions of the polar climate. Main reasons for this are the lack of observations in high latitudes, insufficient initialization methods and shortcomings of climate models in representing some of the important climate processes in high latitudes.
This session aims for a better understanding and better representation of the mechanisms that control high latitude variability and predictability of climate in both hemispheres from sub-seasonal to multi-decadal time-scales in past, recent and future climates. Further, the session aims to discuss ongoing efforts to improve climate predictions at high latitudes at various time scales (e.g., usage of additional observations for initialization, improved initialization methods, impact of higher resolution, improved parameterizations, novel verification approaches) and potential teleconnections of high latitude climate with lower latitude climate. We also aim to link polar climate variability and predictions to potential ecological and socio-economic impacts and encourage submissions on this topic.
The session offers the possibility to present results from ongoing projects and research efforts on the topic of high-latitude climate variability and prediction, including, but not limited to, the WMO Year of Polar Prediction (YOPP), NordForsk-project ARCPATH, MOSAiC, and the H2020-projects APPLICATE, INTAROS, BlueAction, and KEPLER.
This session has greatly benefited by the expansion via added contributions from the CL4.11 session on "Arctic climate change: governing mechanisms and global implications" that specifically aims to identify, characterize and quantify the processes and feedbacks that govern amplified Arctic warming and sea ice retreat, and it also addresses the climate impacts on the lower latitudes associated with Arctic changes.

The Arctic Realm is changing rapidly and the fate of the cryosphere, including Arctic sea ice, glaciers and ice caps, is a source of concern. Whereas sea ice variations impact the radiative energy budget, thus playing a role in Arctic amplification, the Greenland Ice Sheet retreat contributes to global sea level rise. Moreover, through various processes linking the atmosphere, ice and ocean, the change in the Arctic realm may modify the atmospheric and ocean circulation at regional to global scales, the freshwater budget of the ocean and deep-water formation as well as the marine and terrestrial ecosystems, including productivity. The processes and feedbacks involved operate on all time scales and it require a range of types of information to understand the processes, drivers and feedbacks involved in Arctic changes, as well as the land-ocean-cryosphere interaction. In this session, we invite contributions from a range of disciplines and across time scales, including observational (satellite and instrumental) data, historical data, geological archives and proxy data, model simulations and forecasts, for the past, present and future climate. The common denominator of these studies will be their focus on a better understanding of mechanisms and feedbacks on short to long time scales that drive Arctic and subarctic changes and their impact on climate, ocean and environmental conditions, at regional to global scales, including possible links to weather and climate outside the Arctic.

Climate change (CC) and ocean degradation (OD) are among the greatest threats to humanity. Climate impacts the ocean in massive ways; the ocean is the climate’s most powerful regulator. Separately or combined, they impact every living being and ecological niche, with poorer communities suffering disproportionately. In turn, flora and fauna (incl humans) are suffering. CC and OD are affecting the cryosphere, biodiversity, and food and water security. Given that humans are the prime cause of this devastating change taking us beyond our planetary boundaries, geoethical issues come to the fore.
The 2020 EGU Declaration of the Significance of Geoscience highlights the need for massive and widespread action to help people around the world to become literate about the changes affecting their and their offsprings’ and communities’ lives. The more people are literate about these changes, the more they can make informed decisions, adapt and mitigate. Previous General Assemblies have addressed climate change literacy (CL). Ocean literacy (OL) has developed strongly in recent years, especially with impetus from the UN Ocean Decade. Ocean-climate literacy (OCL) is an imperative that needs to be addressed massively and urgently, both within and beyond the EGU.
We invite colleagues to submit contributions on any aspects of OCL; this can, of course, include CL (without the ocean) and OL (without the climate). We welcome papers related, eg, to learning processes/experiences, instructional materials, curricular innovation, learning games, citizen initiatives, Ocean Decade activities, evaluation, well-used methods, novel approaches and policies, eg, 1. make OCL an essential component in all subjects and at all levels of education; 2. require all people in positions of responsibility (eg, mayors, teachers, doctors, CEOs, ministers, et al) to pass exams on the basics of climate and/or ocean before taking office. Of particular interest are literacy actions that bring in geoethical dimensions. (If your paper is primarily on geoethics, then a better home is the EGU session on geoethics.) The broad aims of such OCL might include encouraging an intergenerational outlook, developing a sense of the geoethical dimensions of OCL, understanding complexities and implementing solutions.
This session is an opportunity for ECSs, scientists, educators, policy influencers, learning resource developers and other practitioners to share their experience, expertise and research on CL and OL.

The ocean floor hosts a tremendous variety of forms that reflect the action of a range of tectonic, sedimentary, oceanographic and biological processes at multiple spatio-temporal scales. Many such processes are hazards to coastal populations and offshore installations, and their understanding constitutes a key objective of national and international research programmes and IODP expeditions. High quality bathymetry, especially when combined with sub-seafloor and/or seabed measurements, provides an exciting opportunity to integrate the approaches of geomorphology and geophysics, and to extend quantitative geomorphology offshore. 3D seismic reflection data has also given birth to the discipline of seismic geomorphology, which has provided a 4D perspective to continental margin evolution.
This interdisciplinary session aims to examine the causes and consequences of geomorphic processes shaping underwater landscapes, including submarine erosion and depositional processes, submarine landslides and canyons, sediment transfer and deformation, volcanic activity, fluid migration and escape, faulting and folding, and other processes acting at the seafloor. The general goal of the session is to bring together researchers who characterise the shape of past and present seafloor features, seek to understand the sub-surface and surface processes at work and their impacts, or use bathymetry and/or 3D seismic data as a model input. Contributions to this session can include work from any depth or physiographic region, e.g. oceanic plateaus, abyssal hills, mid-ocean ridges, accretionary wedges, and continental margins (from continental shelves to abyss plains). Datasets of any scale, from satellite-predicted depth to ultra high-resolution swath bathymetry, sub-surface imaging and sampling, are anticipated.
This session is organised by the IAG Submarine Geomorphology Working Group.

Contributions are invited on innovative observational, theoretical and modelling studies concerning physical processes in coastal and shelf seas. Processes can include hydrodynamics (e.g., waves, tides, river plumes, currents and Stokes drift, upwelling, eddies, density structures), transport of material (e.g., sediments, contaminants, litter, nutrients), and morphodynamics and sea-bed structure (e.g., evolution of bed forms, banks, Holocene-Antropogene strata or basin shape). Study areas are envisaged between the base of the shelf break and the seaward limit of the surf zone, including tidal basins. However, contributions on processes outside these geographical limits will be considered where they significantly influence processes within these limits. Equally, contributions on climate dynamics, biogeochemistry, and man-made structures will be considered where they significantly influence, or are significantly influenced by, the processes aimed at in this session. Special attention will be given to interactions between physics, biology and biogeochemistry and to global to local scaling of processes, their relative importance, and the representation of these transitions in models.

Oceanographic processes at coastal scales present important differences about deep water oceanography, which result in higher prediction errors for the land-ocean border. In shallow water coastal domains, the bottom topography exerts a strong control on wave/current/turbulence fields and additional factors need to be accounted for. These factors include stratification, land boundary conditions and the interaction with coastal infrastructure. Moreover, the strong non-linear interactions (breaking waves, nearshore circulation), the choice of numerical strategy (nested meshes, finite-elements) or the modulations in restricted domains (suspended sediment clouds, vegetation filtering) may also play a critical role in the predictive quality. Coastal observations are therefore necessary to drive and calibrate numerical models, combining in-situ data and satellite images. The advent of new satellite capabilities (resolution and sensors like for instance those of the Sentinel constellation) and new modelling advances (new couplings, unstructured grids) together with enhanced Coastal Observatories are leading to a qualitative advance of coastal oceanography. The introduction of Artificial Intelligence, Machine Deep Learning and Big Data techniques can speed up these advances and facilitate applications.
These issues become more relevant in a framework of changing climate, since coastal/transitional areas are more strongly impacted by climate (changing domains due to sea-level rise, impulsive river discharges). Because of these reasons, it is timely to discuss recent advances in: a) coastal coupled hydro-morpho-eco modelling; b) aggregation of in-situ/satellite/numerical data from different sources; c) knowledge-based coastal applications; d) ethical constraints to face large uncertainties. Building upon these challenges, we invite presentations on coastal modelling and coupling, local and boundary condition assimilation or operational coastal predictions with/out infrastructure interactions. Contributions exploring the potential and currently open issues of Artificial Intelligence and Big Data techniques for coastal applications are also welcome. These and related coastal topics should conform a fruitful session for discussing applications of coastal science to conventional and nature-based interventions under climate change. Please state if you would be interested in submitting your presentation as a full paper to a peer reviewed special issue in a Q1 journal.
The Mediterranean and Black Seas have recently shown clear signs of climate change, including an increase in sea surface temperature for boths basins, salinization of the intermediate and deep waters and a rise in sea level over the last century for the Mediterranean seas and deoxygenation trends for the Black Sea. These trends stress the vulnerability of these environments given their particularities as semi enclosed densely populated basins.
Urgent social and economic drivers need targeted improvements in weather, climate, water, oceans, and relevant environmental information and services. Risks associated with climate variability and extreme environmental events may create social and economic stress which would require new meteorological, hydrological, oceanographic, and climate services in order to ensure the safety and security of populations and the development of adaptive economic strategies.
This session is devoted to scientific advances in multidisciplinary studies at several spatial and temporal scales in the Mediterranean and Black Seas. We seek for new approaches and methods in physical and biogeochemical observations and models as well as in developments in operational oceanography (e.g. the fusion of observations and modelling products as well as downstream product development).

This session welcomes contributions presenting advances in, and approaches to, the modelling, monitoring, and forecasting of internal waves in stratified estuaries, lakes and the coastal oсean.
Internal solitary waves (ISWs) and large-amplitude internal wave packets are a commonly observed event in oceans and lakes. In the oceans ISWs are mainly generated by the interaction of the barotropic tides with bottom topography. Large amplitude solitary waves are energetic events that generate strong currents. They can also trap fluid with larvae and sediments in the cores of waves and transport it a considerable distance. ISWs can cause hazards to marine engineering and submarine navigation, and significantly impact marine ecosystems and particle transport in the bottom layer of the ocean and stratified lakes. Contributions studying flows due to internal waves, their origin, propagation and influence on the surrounding environment are thus of broad scientific importance.
The scope of the session involves all aspects of ISWs generation, propagation, transformation and the interaction of internal waves with bottom topography and shelf zones, as well as an evaluation of the role of internal waves in sediment resuspension and transport. Breaking of internal-waves also drives turbulent mixing in the ocean interior that is important for climate ocean models. Discussion of parameterizations for internal-wave driven turbulent mixing in global ocean models is also invited.

This session provides a platform for interdisciplinary science addressing the continuum from the river source to the sea. A systems approach is indispensable for science-based solutions to sustainably manage complex River-Sea social-ecological systems. Studies linking environmental and social sciences and crossing geographical borders are particularly invited: from the river source and its catchment through estuaries, deltas and marshlands across the freshwater-marine water transition into the coastal sea, including surface-groundwater interaction. Studies addressing the impacts of climate change and extreme events and the impact of human activities on water and sediment quality and quantity, hydromorphology, biodiversity, ecosystem functioning and services of River-Sea continua are of particular interest.
We need to understand how River-Sea Systems function and to address many open questions. How are River-Sea continua changing due to human pressures? What is the impact of processes in the catchment on coastal and marine systems function, and vice versa? How can we discern between human-induced changes or those driven by natural processes from climate-induced variability and extreme events? What will the tipping points of social-ecological system states be and what will they look like? How can we better characterise river-sea systems from the latest generation Earth observation to citizen science based observatories. How can we predict short and long-term changes in River-Sea-Systems to manage them sustainably? What is the limit to which it is possible to predict the natural and human-influenced evolution of River-Sea-Systems? The increasing demand to balance intensive human use and environmental protection in River-Sea Systems requires holistic and integrative research approaches with the ultimate goal of enhanced system understanding as the knowledge base for sustainable management solutions.

The action of a fluid moving over a mobile surface often generates bedforms which in turn influence the flow and how particles are transported. On Earth, bedforms are found in many environments: deserts, rivers, estuaries, continental shelves, deep seas, volcanic regions and glacial environments. Bedforms have also been observed in extra-terrestrial environments, such as on Mars and Venus.
Understanding the links between flow, particle transport, and bedform morphodynamics and stratigraphy is of interest for a wide range of applied and fundamental research. For example, this knowledge is used to manage contemporary environments, such as rivers and coastal seas. Recently, the societal relevance of bedform research has been highlighted, as bedforms are shown to interact with offshore structures. Furthermore, bedform morphology and sedimentology can provide insights into fluid movement across modern and ancient, otherwise unknown, landscapes.
This session aims to highlight many aspects of the complex interaction between flow, sediment transport, stratigraphy and bedforms in terrestrial and planetary environments. The session welcomes contributions from theoretical, field, laboratory and numerical approaches related to bedforms found in aeolian, shallow and deep waters, glacial and planetary environments. The session intends to advance our knowledge of how to decipher information contained in terrestrial and extra-terrestrial bedforms and help foster fruitful discussions on understanding bedform morphodynamics and stratigraphy.

Detailed seabed maps portraying the distribution of geomorphic features, substrates, and habitats are used for a wide range of scientific, maritime industry, and government applications. These maps provide essential information for ocean industry sectors and are used to guide local and regional conservation action. Fundamental to seabed mapping are acoustic remote sensing technologies, including single beam and multibeam echosounders and sidescan, interferometric, and synthetic-aperture sonars. These are deployed on a variety of crewed and robotic surface and underwater platforms. In shallow clear waters, optical sensors including LiDAR, multispectral, and hyperspectral cameras are also increasingly employed from aircraft, drones, and satellites to create maps of the seabed. Innovative data processing, image analysis, and statistical approaches for classification are advancing the field of seabed mapping. These methods are yielding increasingly comprehensive and detailed maps. We welcome submissions that provide insights into the use of advanced technologies, novel processing and analytical approaches, and current and emerging applications in the field of seabed mapping and classification – from shallow coastal waters to the deep seafloor.

Climate induced alterations to key microbial processes, such as net primary production and nitrogen fixation, act alongside changes to the biogeochemical cycling of oxygen and nutrients to affect marine ecosystem structure and function, as well as the ocean carbon cycle. These climate changes operate over a variety of spatiotemporal scales. Today, stratification, warming and acidification are driving global changes in microbial biogeochemistry to affect ocean health. These large-scale, long-term changes are accompanied by the short-term emergence of extremes at the regional scale. And in the past, climate change over glacial-interglacial cycles and even recent multi-decadal variability offer clues to understand how sensitive ocean microbes and biogeochemical cycles are to changes in the climate.
This session seeks submissions, from both observations and modelling efforts, that address the impact of past, present (i.e. historical) and future climate change (including variability) on key microbially-mediated flows. Investigations focussing on net primary production, nitrogen fixation, anaerobic processes in low oxygen zones, and the local to global cycling of nutrients and oxygen are welcome. We also welcome studies that investigate the cascading effects for marine ecosystems to modulate biodiversity and ecosystem services.
Due to the growing pressures on marine resources and the ecosystem services demand, the interest of scientific and politic world is moving to ensure marine ecosystems conservation and environmental sustainable development providing policies to meet the UN 2030 Agenda Goal 14 in order to “Conserve and sustainably use the oceans, seas and marine resources for sustainable development”. To act against the decline of ocean health and to create a framework of stakeholders, the UN proposed the establishment of the “Decade of Ocean Science for Sustainable Development” able to bring regional knowledge and priorities together in an international action plan. Anthropogenic activities could have an impact on the marine environment and affect the ecosystem equilibrium. The marine environment is a dynamic, sensitive and fragile area in which it is advantageous to apply new methodologies and observing methods to increase the quantity and quality of the data. Since ocean dynamics affect the dispersion of pollutants such as chemicals, plastics, noise and invasive species, the ecosystems status should be analyzed through the study of abiotic variables distribution at a proper spatio-temporal scale. To analyze the ocean environmental quality, a large amount of data obtained by global observation systems (e.g. GOOS, EMODNET) is needed, which requires the development of cost-effective technologies for integrated observing systems and to support the study of, e.g., biological variables. The session focuses on marine ecosystems, technological developments for the study of abiotic and biotic factors, with a focus on anthropogenic impacts. Multidisciplinary approaches using data coming from multiple sources are encouraged. Integration of mathematical models, in-situ and remote observations is suggested with the aim to develop methods, technologies and best practices to maintain, restore and monitor biodiversity and to guarantee sustainable use of marine resources. The following topics will be discussed: effects of pollution on biota considering their natural and anthropogenic sources; global change effects on marine ecosystem; new technology development; advanced methods for collection, data processing, and information extraction; benthic and pelagic community dynamics; economic evaluation of natural capital.

Planktonic organisms live in suspension in marine or fresh waters where they have adapted through the slow process of natural evolution (over hundred of thousands of generations) to the harsh turbulent currents of their environment. Therefore, contrary to what the meaning of their name “marine drifter” might let to speculate, their dynamics is potentially different from the one of material bodies passively transported by fluid flows. It is indeed known that these organisms developed many adaptive strategies involving shape and density regulation, swimming activity, aggregation and other mechanisms in order to be sheltered from or to take advantage of turbulent flow features.
Bloom inceptions, thin layers formation, motility, nutrient and light uptakes, specific Lagrangian dynamics, among others are topics involving phytoplankton and turbulence. Jumps, grazing, contact rates, and vertical migration are, among others, topics concerning zooplankton in turbulence. For all planktonic species, adaptive mechanisms in response not only to mechanical, but also chemical and electro-magnetic (such as luminous) cues are topics of great interest.
This interdisciplinary session will welcome works from marine ecologists, oceanographers, fluid-dynamicists, physicists and mathematical modellers. Contributions in the fields of observation, laboratory experimentations, numerical models (such as Computational Fluid Dynamics simulations of non-spherical or motile particles) are welcome. Both phytoplankton and zooplankton will be considered, as well as marine and freshwater studies.

The coastal ocean has been increasingly recognized as a dynamic component of the global carbon budget. This session aims at fostering our understanding of the roles of coastal environments and of exchange processes, both natural or perturbed, along the terrestrial / coastal sea / open ocean continuum in global biogeochemical cycles. During the session recent advancements in the field of coastal and shelf biogeochemistry will be discussed. Contributions focusing on carbon and nutrient and all other element's cycles in coastal, shelf and shelf break environments, both pelagic and sedimentary, are invited.
This session is multidisciplinary and is open to observational, modelling and theoretical studies in order to promote the dialogue. The session will comprise subsections on coastal carbon storage, and on benthic biogeochemical processes.

Ocean-atmosphere flux exchanges of biogeochemically active constituents have significant impacts on global biogeochemistry and climate. Increasing atmospheric deposition of anthropogenically-derived nutrients (e.g., nitrogen, phosphorus, iron) to the ocean influences marine productivity and has associated impacts on oceanic CO2 uptake, and emissions to the atmosphere of climate active species (e.g., nitrous-oxide (N2O), dimethyl-sulfide (DMS), marine organic compounds and halogenated species). Atmospheric inputs of toxic substances (e.g., lead, mercury, cadmium, copper, persistent organic pollutants) into the ocean are also of concern for their impact on ocean ecosystem health. In recent decades the intensive use of plastics has led to significant levels of persistent micro- and nano- plastics being transported into the marine atmosphere and to the ocean, with considerable uncertainty remaining on transport pathways and oceanic impacts. Other influential recent changes include emission reductions for air pollution abatement which have resulted in changes in cloud and aerosol chemical composition, affecting atmospheric acidity, associated chemical processing and impacts via atmospheric deposition on ocean biogeochemistry.
In turn, oceanic emissions of reactive species and greenhouse gases influence atmospheric chemistry and global climate, and induce potentially important chemistry-climate feedbacks. While advances have been made by laboratory, field, and modelling studies over the past decade, we still lack understanding of many of the physical and biogeochemical processes linking atmospheric deposition of chemicals, nutrient availability, marine biological productivity, trace-gas sources and sinks and the biogeochemical cycles governing air-sea fluxes of these climate active species, as well as on the atmosphere-ocean cycle of microplastics and its impact on the environment and climate.
This session will address the above issues on the atmospheric deposition of nutrients and toxic substances to the ocean, the impacts on ocean biogeochemistry, and also the ocean to atmosphere fluxes of climate active species and potential feedbacks to climate. We welcome new findings from measurement programmes (laboratory, in-situ and remote sensing) and atmospheric and oceanic numerical models.

Tides underlie many processes in the ocean, atmosphere and solid Earth, and influence ocean biogeochemistry and ecosystems. They drive ocean mixing, contribute to coastal erosion and sediment transport, and may provide a renewable energy source. Tides influence coastal infrastructure and safe port operations. The severity of storm surge events and coastal flooding is modulated by tides. The relationship between tides and sea ice is also important, not only for sea ice dynamics, but also for transport and mixing processes in the Arctic and Antarctic regions. Interannual variability in the tides may arise from variations in ice extent, changes in ocean stratification or regional climate processes.
Precise knowledge of tides is also necessary for earth observation where the tides are not the main target of study. They play a significant role in determining high-resolution temporal gravity fields from satellite gravimetry as well as sea-level rise estimations from satellite altimetry. Therefore, understanding the evolution of tides from both models and in-situ observations is necessary to understand the implications of tides in current and future climate estimations.
Observations and models of coastal and internal tides continue to develop, as well as their relationships to wind-driven processes and mixing processes. We welcome submissions on observations and models of surface or internal tides in the context of long-term changes in tides, tidal variability, tidal dynamics and the impacts of tides. Submissions are encouraged both from regional and global-scale studies on all aspects of tides.

We invite presentations on ocean surface waves, and wind-generated waves in particular, their dynamics, modelling and applications. This is a large topic of the physical oceanography in its own right, but it is also becoming clear that many large-scale geophysical processes are essentially coupled with the surface waves, and those include climate, weather, tropical cyclones, Marginal Ice Zone and other phenomena in the atmosphere and many issues of the upper-ocean mixing below the interface. This is a rapidly developing area of research and geophysical applications, and contributions on wave-coupled effects in the lower atmosphere and upper ocean are strongly encouraged.

This session welcomes submissions on new insights into the physical processes at the air-sea interface and their role in ocean-atmosphere exchange of heat, gas, momentum, freshwater, and aerosols.
Presentations based on field or satellite observations, numerical models, or theoretical contributions are welcome.
Examples of processes include solar radiation-induced diurnal warming, rain-induced cool and fresh lenses, and processes controlling the formation and properties of the surface microlayer.
Additional focus is on gustiness associated with convection in the atmospheric boundary layer and evaporative cold pools. Further focus is on air-sea interactions in polar regions, in particular related to cold air outbreaks, including the role of sea ice and the effect of leads. Air-sea interaction related to surface temperature and salinity fronts, as well as oceanic meso- and sub-mesoscale dynamics, are also of great interest. Studies considering the variability of biogeochemical properties related to air-sea processes will also be considered.

Oceanographic monitoring and modeling are both widely used to study the pathways and fate of marine pollutants such as hydrocarbons, marine litter (including plastics and microplastics), POPs, HNS, radionuclides, etc. This session focuses on monitoring frameworks, computational tools, experimental results and emerging technologies related to tracing pollutants and their impacts on local, regional and global scales. The coupling with met-oceanographic products from operational oceanography products such as Copernicus Marine Monitoring Environment Service will also be discussed. State-of-the-art observational techniques and protocols, ensemble and multi-model methods, risk assessment algorithms and decision support systems are solicited topics. Integration of modelling and observing systems for both data assimilation and model validation are also very welcome.
We welcome studies based on experimental, observational, and modeling work looking at physical and biogeochemical transformation of pollutants, and impacts on ocean biogeochemistry and ecosystems such as fragmentation, aggregation, biofouling, ingestion but also chemical impacts such as adsorption, transport and desorption of nutrients, metals and microbes. Studies that link effects to broader ecosystem stressors like environmental degradation and climate change are particularly welcome. Monitoring and modeling the oil spill transport under the ice conditions are also appreciated, which is related to the increase in shipping traffic and melting the Polar ice as a consequence of the climate changes.
Key questions of the session are identified as follows: Which factors affect the dispersion of the pollutants in the marine environment? What happens to the contaminants on the ocean’s surface, in the water column and sediments? How do marine pollutants interact with marine habitats? How do they influence marine and maritime resources? How should Integrated Coastal Zone Management (ICZM) protocols be optimized to minimize negative impact on the coastal zone?
Impacts of pollutants, including chemicals, microplastics, light, noise, and thermal pollution, on the marine ecosystems and resilience to pollution events are also important subjects for discussion: What is the behavior of oil, marine litter, heavy metals, and other pollutants in the water column, on various beach sediments, rocks and seabed? e.g., what is the biodegradation rate of oil droplets in the water column and what are the controlling factors? What is the rate of fragmentation, biofouling, and sedimentation of plastics? What are the mechanisms of beaching, seabed deposition, and resuspension of marine pollutants and what are the ways of entering the marine food chains (including human consumption)? What is the impact of light, noise, and thermal pollution on the marine environment and habitats?
Advanced remote sensing capabilities have provided unprecedented opportunities for monitoring and studying the ocean environment as well as improving ocean and climate predictions. Synthesis of remote sensing data with in situ measurements and ocean models have further enhanced the values of oceanic remote sensing measurements. This session provides a forum for interdisciplinary discussions of the latest advances in oceanographic remote sensing and the related applications and to promote collaborations.
We welcome contributions on all aspects of the oceanic remote sensing and the related applications. Topics for this session include but are not limited to: physical oceanography, marine biology and biogeochemistry, biophysical interaction, marine gravity and space geodesy, linkages of the ocean with the atmosphere, cryosphere, and hydrology, new instruments and techniques in ocean remote sensing, new mission concepts, development and evaluation of remote sensing products of the ocean, and improvements of models and forecasts using remote sensing data. Applications of multi-sensor observations to study ocean and climate processes and applications using international (virtual) constellations of satellites are particularly welcome.

NEMO (Nucleus for European Modelling of the Ocean) is a state-of-the-art modelling framework of the ocean that includes components for the ocean dynamics, the sea-ice and the biogeochemistry, so as a nesting package allowing to set up zooms and a versatile data assimilation interface (see https://www.nemo-ocean.eu/).
NEMO is used by a large community in Europe and world-wide (~200 projects, ~100 publications each year) covering a wide range of applications : oceanographic research, operational oceanography, seasonal forecast and climate projections.
NEMO is in particular used in 6 Earth System Models within CMIP6 and in Copernicus Marine Services (CMEMS) model-based products.
This session will provide a forum to properly address the new scientific advances in numerical modelling of the ocean and their implication for NEMO developments associated with:
• Ocean dynamics at large to coastal scales, up to 1km resolution ;
• Ocean biogeochemistry
• Sea-ice
• New numerical schemes associated to energy conservation constraints
• High performance computing challenges and techniques
The session will cover both research and operationnal activities contributing to new analysis, ideas and developments of ocean numerical models.
Presentations of results based on new NEMO functionalities and new NEMO model configurations are welcome.

Since its inception, data assimilation has proven to be enormously useful in the most varied fields throughout the Earth Sciences. It is certainly essential in meteorology, where the short-range forecasts would otherwise be almost impossible. In oceanography, its development has been slower, partly due to the smaller number of continuous and stable observations, and partly due to the fewer studies that show the importance of ocean forecasts for societal benefit. However, recently, these techniques are used more and more widely, both in operational oceanography and to produce climate reconstructions. Although the techniques are similar to those used in the atmospheric field, they have to deal with particularities due to the different environment, where the boundary conditions, open and closed, have greater importance, and the sparsity of observations poses unique challenges.
In this session, we welcome contributions describing data assimilation techniques, both methodological and case studies, in the oceanographic field. We welcome presentations of new techniques or new types of observations that cover every aspect of data assimilation, including varied applications of data assimilation, both in coastal seas and the open ocean.

The Copernicus Marine Service (CMEMS) provides regular and systematic reference information on the physical (including sea-ice and wind waves) and biogeochemical states of the global ocean and European regional seas. This capacity encompasses the description of the current ocean state (analysis and near-real time observations), the prediction of the ocean state a few days ahead (forecast), and the provision of consistent retrospective data records for recent decades (reanalyses and reprocessed observations). CMEMS provides a sustainable response to private and public user needs, for academic, operational and private-sector activities and to support policies. The Copernicus Marine Service has started a new 7-yr phase covering 2021-2027 (CMEMS2).
The session focuses on the main CMEMS activities on ocean modelling and coupling with other components of the climate system; data assimilation; processing of observations, impact and design of in-situ and satellite observing systems, data science; verification, validation and uncertainty estimates of CMEMS products; monitoring and long-term assessment of the ocean physical and biogeochemical states. Presentations dealing with the use and impact of CMEMS products for downstream applications, including support to policies and directives, are also welcome.
The session will also address research activities that are required to maintain a state-of-the-art and user responsive CMEMS and to prepare CMEMS long-term evolutions: pan-European coastal zone monitoring, coupling with coastal systems and rivers, marine biology including higher trophic level modelling, Arctic ocean monitoring and forecasting and uptake of future Sentinel missions, air/sea CO2 fluxes and carbon uptake, long-term regional ocean projections both for physics and biogeochemistry, digital oceans, big data and data science (AI, machine learning, etc).
Presentations are not limited to research teams directly involved in the Copernicus Marine Service and participation from external teams is strongly encouraged (e.g. from H2020 projects relevant to CMEMS and downstream applications).
The session gathers geoscientific aspects such as dynamics, reactions, and environmental/health consequences of radioactive materials that are massively released accidentally (e.g., Chernobyl and Fukushima nuclear power plant accidents, wide fires, etc.) and by other human activities (e.g., nuclear tests).
The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Thus, the radioactive contamination problem is multi-disciplinary. In fact, this topic involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic and ecosystem, and its relations with human and non-human biota. The topic also involves hazard prediction and nowcast technology.
By combining 35 years (> halftime of Cesium 137) monitoring data after the Chernobyl Accident in 1986, 10 years dense measurement data by the most advanced instrumentation after the Fukushima Accident in 2011, and other events, we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents.
The following specific topics have traditionally been discussed:
(a) Atmospheric Science (emissions, transport, deposition, pollution);
(b) Hydrology (transport in surface and ground water system, soil-water interactions);
(c) Oceanology (transport, bio-system interaction);
(d) Soil System (transport, chemical interaction, transfer to organic system);
(e) Forestry;
(f) Natural Hazards (warning systems, health risk assessments, geophysical variability);
(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).
The session consists of updated observations, new theoretical developments including simulations, and improved methods or tools which could improve observation and prediction capabilities during eventual future nuclear emergencies. New evaluations of existing tools, past nuclear contamination events and other data sets also welcome.

The multitude of processes of various scales occurring simultaneously under strong winds in the air and sea boundary layers presents a true challenge for nonlinear science. We want to understand the physics of these processes, their specific role, their interactions and how they can be probed remotely, how these processes differ from their counterparts under moderate/weak winds. We welcome theoretical, experimental, and numerical works on all aspects of processes in turbulent boundary layers above and below the ocean surface. Although we are particularly interested in the processes and phenomena occurring under strong wind conditions, the works concerned with similar processes under weaker winds which might provide an insight for rough seas are also welcomed. We are also very interested in works on remote sensing of these processes.
The areas of interest include the processes at and in the vicinity of the interface (nonlinear dynamics of surface water, wave-turbulence interactions, wave breaking, generation and dynamics of spray and air bubbles, thermodynamics of the processes in the boundary layers, heat and gas exchange), all the processes above and below the air/water interface, as long as they are relevant for strong wind conditions (such as, e.g. inertial waves generated by changing winds). Relevant nonlinear biological phenomena are also welcomed.
The main aim of the session is to initiate discussion of the multitude of processes active under strong winds across the narrow specializations as a step towards creating an integrated picture. Theoretical, numerical, experimental and observational works are welcomed.

In his seminal work "Weather Prediction by Numerical Process" in 1922, Lewis Fry Richardson proposed his famous cascade picture qualitatively, for a turbulent flow where the energy is transferred from large scale structures to small scale ones, until reaching viscosity scales where it is converted to heat. This picture now has been widely adopted to describe different type of turbulent phenomena, for not only the classical hydrodynamic turbulence, but also, not limited to, the movement of atmosphere and oceans.
After 100 years of developments, the concept of cascades has been extended significantly. Now, it describes mainly the nonlinear interactions crossing a large range of scales where scale invariants might emerge spontaneously. More precisely, balances between the external forcing and the dissipation are expected for a turbulent system. However, due to the complexity of atmospheric or oceanic systems, such as earth rotation, stratification, large aspect ratio, mesoscale eddies, ocean current, tidal, waves, etc., the exact balance is still unknown. We still lack an efficient methodology to diagnose the scale-to-scale energy or other physical quantities fluxes to characterize the cascade quantitatively, e.g., strength, direction, etc.
With the increasing capability of remote sensing, computational fluid dynamics, field observation, etc., we have accumulated a large amount of field data. It is now a suitable time to celebrate the 100th Anniversary of Richardson's idea of cascades in the geosciences, and to understand it quantitatively.
This interdisciplinary session welcomes theoretical, methodological, laboratory, data analysis works that aim to characterize the cascade in atmosphere and oceans and other fields.

This session invites innovative Earth system and climate studies based on geodetic measuring techniques. Modern geodetic observing systems document a wide range of changes in the Earth’s solid and fluid layers at very diverging spatial and temporal scales related to processes as, e.g., glacial isostatic adjustment, the terrestrial water cycle, ocean dynamics and ice-mass balance. Different time spans of observations need to be cross-compared and combined to resolve a wide spectrum of climate-related signals. Geodetic observables are also often compared with geophysical models, which helps to explain observations, evaluate simulations, and finally merge measurements and numerical models via data assimilation.
We appreciate contributions utilizing geodetic data from diverse geodetic satellites including altimetry, gravimetry (CHAMP, GRACE, GOCE and GRACE-FO), navigation satellite systems (GNSS and DORIS) or remote sensing techniques that are based on both passive (i.e., optical and hyperspectral) and active (i.e., SAR) instruments. We welcome studies that cover a wide variety of applications of geodetic measurements and their combination to observe and model Earth system signals in hydrological, ocean, atmospheric, climate and cryospheric sciences. Any new approaches helping to separate and interpret the variety of geophysical signals are equally appreciated. Contributions working towards any of the goals of the Inter-Commission Committee on "Geodesy for Climate Research" (ICCC) of the International Association of Geodesy (IAG) are also welcomed in this session.
With author consent, highlights from this session will be tweeted with a dedicated hashtag during the conference in order to increase the impact of the session.

Tsunamis can produce catastrophic damage on vulnerable coastlines, essentially following major earthquakes, landslides, extreme volcanic activity or atmospheric disturbances. After the disastrous tsunamis in 2004 and 2011, tsunami science has been continuously growing and expanding its scope to new fields of research in various domains, and also to regions where the tsunami hazard was previously underestimated.
The spectrum of topics addressed by tsunami science nowadays ranges from the “classical” themes, such as analytical and numerical modelling of different generation mechanisms (ranging from large subduction earthquakes to local earthquakes generated in tectonically complex environments, from subaerial/submarine landslides to volcanic eruptions and atmospheric disturbances), propagation and run-up, hazard-vulnerability-risk assessment, especially with probabilistic approaches able to quantify uncertainties, early warning and monitoring, to more “applied” themes such as the societal and economic impact of moderate-to-large events on coastal local and nation-wide communities, as well as the present and future challenges connected to the global climate change.
This session, co-organized with OS4, SM4, GMPV9, GM and AS, welcomes multidisciplinary as well as focused contributions covering any of the aspects mentioned above, encompassing field data, geophysical models, regional and local hazard-vulnerability-risk studies, observation databases, numerical and experimental modeling, real time networks, operational tools and procedures towards a most efficient warning, with the general scope of improving our understanding of the tsunami phenomenon, per se and in the context of the global change, and our capacity to build safer and more resilient communities.

Recently, there have been significant breakthroughs in the use of fiber-optic sensing techniques to interrogate cables at high precision both on land and at sea as well as in boreholes and at the surface. Laser reflectometry using both fit-to-purpose and commercial fiber-optic cables have successfully detected a variety of signals including microseism, local and teleseismic earthquakes, volcanic events, ocean dynamics, etc. Other laser-based techniques can be used to monitor distributed strain, temperature, and even chemicals at a scale and to an extent previously unattainable with conventional geophysical methods.
We welcome any contributions to recent development in the fields of applications, instrumentation, and theoretical advances for geophysics with fiber-optic sensing techniques. These may include - but are not limited to - application of fiber-optic cables or sensors in seismology, geodesy, geophysics, natural hazards, oceanography, urban environment, geothermal application, etc. with an emphasis on laboratory studies, large-scale field tests, and modeling. We also encourage contributions on data analysis techniques, machine learning, data management, instruments performances and comparisons as well as new experimental field studies.
Satellite altimetry provides the possibility to observe key parts of the hydrosphere, namely the ocean, ice, and continental surface water from space. Since the launch of Topex/Poseidon in 1992, the applications of altimetry have expanded from the open oceans to coastal zones, inland water, land, and sea ice. Today, seven missions are in orbit, providing dense and near-global observations of surface elevation and several other parameters. Satellite altimetry has become an integral part of the global observation of the Earth‘s system and changes therein.
In recent years, new satellite altimetry missions have been launched carrying new instruments; the CryoSat-2/Sentinel-3 missions equipped with a Delay/Doppler altimeter, the Saral AltiKa mission carrying the first Ka-band altimeter, and 2018 launched six beam photon-counting laser altimeter onboard NASAs ICESat-2. Further, new orbits with high inclination and long-repeat time are used for CryoSat-2 and ICESat-2.
Fully exploiting this unprecedented availability of observables will enable new applications and results but also require novel and adapted methods of data analysis.
Across the different applications for satellite altimetry, the data analysis and underlying methods are similar and a knowledge exchange between the disciplines has been proofed to be fruitful.
In this multidisciplinary altimetry session, we therefore invite contributions which discuss new methodology and applications for satellite altimetry in the fields of geodesy, hydrology, cryosphere, oceanography, and climatology.
Topics of such studies could for example be (but not limited to); creation of robust and consistent time series across sensors, validation experiments, combination of radar and laser altimetry for e.g. remote sensing of snow, classification of waveforms, application of data in a geodetic orbit, retracking, or combination with other remote sensing data sets.
The International Monitoring System (IMS) of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) senses the solid Earth, the oceans and the atmosphere with a global network of seismic, infrasound, and hydroacoustic sensors as well as detectors for atmospheric radioactivity. The primary purpose of the IMS data is for nuclear explosion monitoring regarding all aspects of detecting, locating and characterizing nuclear explosions and their radioactivity releases. On-site verification technologies apply similar methods on smaller scales as well as geophysical methods such as ground penetrating radar and geomagnetic surveying with the goal of identifying evidence for a nuclear explosion close to ground zero. Papers in this session address advances in the sensor technologies, new and historic data, data collection, data processing and analysis methods and algorithms, uncertainty analysis, machine learning and data mining, experiments and simulations including atmospheric transport modelling. This session also welcomes papers on applications of the IMS and OSI instrumentation data. This covers the use of IMS data for disaster risk reduction such as tsunami early warning, earthquake hazard assessment, volcano ash plume warning, radiological emergencies and climate change related monitoring. The scientific applications of IMS data establish another large range of topics, including acoustic wave propagation in the Earth crust, stratospheric wind fields and gravity waves, global atmospheric circulation patterns, deep ocean temperature profiles and whale migration. The use of IMS data for such purposes returns a benefit with regard to calibration, data analysis methods and performance of the primary mission of monitoring for nuclear explosions.

Through a wealth of geospatial data, growing computational power, and demonstrated success of application across many fields, artificial intelligence (in particular, machine learning) promises to advance our understanding of natural hazards and our ability to predict and respond to natural disasters. The ITU/WMO/UNEP Focus Group AI for Natural Disaster Management (FG-AI4NDM) is building a community of experts and stakeholders to identify best practices in the use of AI for data processing, improved modeling across spatiotemporal scales, and providing effective communication. This multidisciplinary FG-AI4NDM-session invites contributions addressing challenges related to floods, landslides, earthquakes, volcanic eruptions, tsunamis, among others, as well as multi-hazard. It also welcomes presentations on novel AI methods (including advances in automated annotation, explainability, etc.), which are hazard agnostic.
Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

This session invites submissions spanning modelling and observational approaches towards providing an overview of the state-of-the-art of application of these novel methods for predicting and monitoring our earth system. This includes (but it is not restricted to):
- the use of machine learning to improve forecast skill
- generate significant speedups
- design new parameterization schemes
- emulate numerical models.
Please consider submitting abstracts focussed on ML applied to observations and modelling of climate processes to the companion "ML for Climate Science" session.
The 2021-2022 Hunga Tonga-Hunga Ha'apai eruption in Tonga was among the largest of recent decades. The event was notable for its high intensity, generating a convective column that rapidly ascended well into the stratosphere; for the atmospheric pressure wave generated by the explosion, which was detected globally; and for generating a tsunami that was observable across Pacific Ocean shorelines. Following a series of preceding seismic and explosive events since December 2021, the sustained phase of the eruption on 15th January was relatively short lived, but the associated pressure wave and tsunami impacts were the most far-reaching since the eruption of Krakatau volcano in 1883. Tsunamis were recorded both locally and in the far-field, but their mechanism(s) remains uncertain; in the near field being from either (or both of) the collapsing eruption column or a phreatomagmatic explosion as the erupting mass mixed with sea water. In the far-field the tsunamis are possibly best explained by the massive atmospheric pressure wave, that is the first instrumentally recorded eruption-generated event of its type, which affected the entire global atmosphere and ionosphere, causing the observed infrasound waves and unusual long-period seismic resonances.
This interdisciplinary late-breaking session welcomes contributions from all disciplines involved in local and global observations of this eruption and its effects, including remote sensing observations and modeling as well as hazard assessment and estimation of damage and long-term consequences.

On 9 August 2021, the Intergovernmental Panel on Climate Change (IPCC) released the first volume of its 6th Assessment Report (AR6). The Working Group I contribution to the Report (Climate Change 2021: The Physical Science Basis) synthesises over 14,000 publications and represents the most comprehensive and up-to-date assessment of the climate system and climate change. Crucially, the Report highlights the unprecedented and potentially irreversible influence of anthropogenic climate forcing, and for the first time, explicitly states that human influence on the climate system is unequivocal.
This short course will be a panel discussion where authors and contributors of Working Group I unpack how the IPCC 6th Assessment Report (AR6) is produced, provide personal behind-the-scenes insight on its development, and discuss its global impact, including how it is used to inform policy. Authors of the report will share their experiences of working on the report before and through the COVID pandemic. Panelists will also emphasise various ways in which scientists of all career stages can contribute to the IPCC process. Ample time will be allocated for open discussion for the audience to ask related questions to the panelists.
For more information about the AR6 please visit the IPCC website: https://www.ipcc.ch/.
We have developed an open source software package in python for ground-based GNSS reflections – gnssrefl (https://github.com/kristinemlarson/gnssrefl). This new software supports geoscientists wishing to measure in situ snow accumulation, permafrost melt, firn density, tides, and lake/river levels. We have developed videos (hosted on youtube) to help new users understand both the basic concepts of GNSS reflections and how to install and run the gnssrefl code. More than a dozen use cases are available online; Jupyter Notebooks have been developed as well. We envision the EGU tutorial session to be hands-on and interactive, with a focus on demonstrating the gnssrefl software and online tools (https://gnss-reflections.org), examining and discussing environmental results derived from GNSS data taken from public archives, and analyzing new datasets suggested by the students.
Public information:
We have developed an open source code in python (gnssrefl) that allows users to measure either water levels or snow accumulation using GNSS data. This session will be devoted to helping users understand how to run and install the code. Please see the github (https://github.com/kristinemlarson/gnssrefl) repository for some tips on how to install the gnssrefl package on your local machine. We currently support the python code on linux and macs, with docker images for these and PCs. We also have links to jupyter notebooks. There is a complementary web app at https://gnss-reflections.org.

Importance of the OSPP competition. Presentation of the OSPP Certificate winner.
The increasing amount of data from an increasing number of spacecraft in our solar system shouts out for new data analysis strategies. There is a need for frameworks that can rapidly and intelligently extract information from these data sets in a manner useful for scientific analysis. The community is starting to respond to this need. Machine learning, with all of its different facets, provides a viable playground for tackling a wide range of research questions in planetary and heliospheric physics.
We encourage submissions dealing with machine learning approaches of all levels in planetary sciences and heliophysics. The aim of this session is to provide an overview of the current efforts to integrate machine learning technologies into data driven space research, to highlight state-of-the art developments and to generate a wider discussion on further possible applications of machine learning.

The ionospheres and (induced) magnetospheres of unmagnetized and weakly magnetized bodies with substantial atmospheres (e.g. Mars, Venus, Titan, Pluto and comets) are subject to disturbances due to solar activity, interplanetary conditions (e.g. solar flares, coronal mass ejections and solar energetic particles), or for moons, parent magnetospheric activity. These objects interact similarly as their magnetized counterparts but with scientifically important differences.
As an integral part of planetary atmospheres, ionospheres are tightly coupled with the neutral atmosphere, exosphere and surrounding plasma environment, possessing rich compositional, density, and temperature structures. The interaction among neutral and charged components affects atmospheric loss, neutral winds, photochemistry, and energy balance within ionospheres.
This session invites abstracts concerning remote and in-situ data analysis, modelling studies, comparative studies, instrumentation and mission concepts for unmagnetized and weakly magnetized solar system bodies.

Cosmic rays carry information about space and solar activity, and, once near the Earth, they produce isotopes, influence genetic information, and are extraordinarily sensitive to water. Given the vast spectrum of interactions of cosmic rays with matter in different parts of the Earth and other planets, cosmic-ray research ranges from studies of the solar system to the history of the Earth, and from health and security issues to hydrology and climate change.
Although research on cosmic-ray particles is connected to a variety of disciplines and applications, they all share similar questions and problems regarding the physics of detection, modeling, and the influence of environmental factors.
The session brings together scientists from all fields of research that are related to monitoring and modeling of cosmogenic radiation. It will allow sharing of expertise amongst international researchers as well as showcase recent advancements in their field. The session aims to stimulate discussions about how individual disciplines can share their knowledge and benefit from each other.
We solicit contributions related but not limited to:
- Health, security, and radiation protection: cosmic-ray dosimetry on Earth and its dependence on environmental and atmospheric factors
- Planetary space science: satellite and ground-based neutron and gamma-ray sensors to detect water and soil constituents
- Neutron and Muon monitors: detection of high-energy cosmic-ray variations and its dependence on local, atmospheric, and magnetospheric factors
- Hydrology and climate change: low-energy neutron sensing to measure water in reservoirs at and near the land surface, such as soils, snow pack, and vegetation
- Cosmogenic nuclides: as tracers of atmospheric circulation and mixing; as a tool in archaeology or glaciology for dating of ice and measuring ablation rates; and as a tool for surface exposure dating and measuring rates of surficial geological processes
- Detector design: technological advancements for the detection of cosmic rays
- Cosmic-ray modeling: advances in modeling of the cosmic-ray propagation through the magnetosphere and atmosphere, and their response to the Earth's surface
- Impact modeling: How can cosmic-ray monitoring support environmental models, weather and climate forecasting, irrigation management, and the assessment of natural hazards

The heliosphere is permeated with energetic particles of different compositions, energy spectra and origins. Two major populations of these particles are galactic cosmic rays (GCRs), which originate from outside of the heliosphere and are constantly detected at Earth, and solar energetic particles (SEPs) which are accelerated at/near the Sun during solar flares or by shock fronts associated with the transit of coronal mass ejections. Enhancements in energetic particle fluxes at Earth pose a hazard to humans and technology in space and at high altitudes. Within the magnetosphere, energetic particles are present in the radiation belts, and particle precipitation is responsible for the aurora and for hazards to satellites. Energetic particles have also been shown to cause changes is the chemistry of the middle and upper atmosphere, thermodynamic effects in the upper troposphere and lower stratosphere region, and can influence components of the global electric circuit. This session will aim to address the transport of energetic particles through the heliosphere, their detection at Earth and the effects they have on the terrestrial atmosphere when they arrive. It will bring together scientists from several fields of research in what is now very much an interdisciplinary area. The session will allow sharing of expertise amongst international researchers as well as showcase the recent advances being made in this field, which demonstrate the importance of the study of these energetic particle populations.

The Earth's inner magnetosphere contains different charged particle populations, such as the Van Allen radiation belts, ring current particles, and plasmaspheric particles. Their energy range varies from eV to several MeV, and the interplay among the charged particles provides feedback mechanisms that couple all those populations together. Ring current particles can generate various waves, for example, EMIC waves and chorus waves, which play important roles in the dynamic evolution of the radiation belts through wave-particle interactions. Ring current electrons can be accelerated to relativistic radiation belt electrons. The plasmaspheric medium can also affect these processes. In addition, precipitation of ring current and radiation belt particles will influence the ionosphere, while up-flows of ionospheric particles can affect dynamics in the inner magnetosphere. Understanding these coupling processes is crucial.
While the dynamics of outer planets’ magnetospheres are driven by a unique combination of internal coupling processes, these systems have several fascinating similarities which make comparative studies particularly interesting. We invite a broad range of theoretical, modeling, and observational studies focusing on the dynamics of the inner magnetosphere of the Earth and outer planets, including the coupling of the inner magnetosphere and ionosphere and coupling between the solar wind disturbances and various magnetospheric processes. Contributions from all relevant fields, including theoretical studies, numerical modeling, observations from satellite and ground-based missions are welcome. In particular, we encourage presentations using data from MMS, THEMIS, Van Allen Probes, Arase (ERG), Cluster, cube-sat missions, Juno, SuperDARN, magnetometer, optical imagers, IS-radars, and ground-based VLF measurements.
The present state of Earth and other rocky planets are an expression of dynamical and chemical processes occurring throughout their history. In particular, giant impacts, core formation and magma-ocean crystallisation and other processes occurring in the early solar system set the stage for the long-term evolution of terrestrial planets. These early processes can happen simultaneously or in recurring stages, and are ultimately followed by progressive crustal growth, long-term mantle mixing/differentiation, core-mantle interaction, as well as inner-core crystallization. The rock-record, through geochemistry and magnetism, is used to interrogate changes in the tectono-thermal regime of Earth’s interior through time, while seismic imaging and gravity data, for instance, provide a snapshot of processes occurring in the contemporary mantle, crust and core. These classes of observations may be linked through geodynamic models, whose accuracy is underpinned by the physical properties (e.g., viscosity and density) of its constituent phases (minerals, melts and fluids). Information on the fundamental thermodynamic and physical behaviour of phases is subject to constant advance via experimental and ab-initio techniques.
This session aims to provide a holistic view of the formation, dynamics, structure and composition of Earth and the evolution of terrestrial bodies by bringing together studies from geophysics, geodynamics, mineral physics, geochemistry, and petrology. This session welcomes contributions focused on data analysis, modeling and experimental work that address the formation and evolution of terrestrial planets and moons in the Solar System, and around other stars.

In June 2021, NASA and ESA selected a fleet of three international missions to planet Venus. 28 years since the Magellan orbital radar mapping mission, and 37 years since the last Venera/VeGa landing, Venus remains our enigmatic neighbour. Shrouded by its dense atmosphere, the surface is only studied from space at radar frequencies and in a limited number of near-infrared spectral windows. Many significant questions remain on the current state of Venus, suggesting major gaps in our understanding of how our nearest planet's evolutionary pathway diverged from Earth's. Did Venus ever have an ocean, how and when did greenhouse conditions develop, and to what degree do volcanic eruptions still affect the surface and atmosphere today? Comparing the interior, surface and atmosphere evolution of Earth and Venus is essential to understanding what processes have shaped our own planet. This is particularly relevant in a decade where we expect hundreds of Earth- & Venus-size exoplanets to be discovered. The session will also address how these new missions will better understand Venus’ early evolution and past and present habitability.

Understanding the structures and dynamics of the core of a planet is essential to construct a global geochemical and geodynamical model, it has implication on its thermal, compositional and orbital evolution.
Remote sensing of planets interior from space and ground-based observations is entering a new era with perspectives in constraining their core structures and dynamics. Meanwhile, increasingly accurate seismic and magnetic data provides unprecedented images of the Earth's deep interior. Unraveling planetary cores structures and dynamics requires a synergy between many fields of expertise, such as mineral physics, geochemistry, seismology, fluid mechanics or geomagnetism. In such a cross-disciplinary context, we identify the need to combine observations, e.g. from geo/paleo/rock magnetism, to generate field models and carefully compare their properties with numerical simulations of the dynamo process. This requires community-wide efforts to share data and models in standardized formats, which we aim to address.
This session welcomes contributions from all the disciplines mentioned following theoretical, numerical, observational or experimental approaches, with the aim to proceed towards an integrated, self-consistent picture of planetary core's structure, dynamics, magnetic field and their evolution.

Processes controlling the global cycles of volatiles (e.g., C, H, O, S) across reservoirs regulate planetary climate and habitability. Their cycling pathways and efficiency are dependent on numerous factors including the presence of liquid water and the tectonic mode; and involves the atmosphere, hydrosphere, crust, mantle and even the core.
On Earth, major volatile cycles are balanced to first order through ingassing and outgassing, mainly occurring at subduction zones, and major sites of volcanism (i.e., mid-ocean ridges and hotspots), respectively. In planetary interiors, volatiles are partitioned into the existing minerals, or stabilize minor phases such as diamond or various hydrous phases in the mantle and crust, something that directly influences the spatial distribution of melt formation as well as rock properties. Conversely, melt transport induces volatile exchanges between planetary reservoirs and favours outgassing. Outgassing, in turn, will regulate planetary climates, hence influencing the habitability.
The aim of this session is to bring together numerical, experimental and observational expertise from Earth and Planetary Sciences to advance the understanding of interior-atmosphere coupling and volatile exchange and evolution on Earth and terrestrial (exo)planets, as well as the role of those volatiles on the interior composition and dynamics. This session features contributions on topics including volatile cycling, melt and volatile transport, mineral-melt phase relations, geophysical detections, tectonic regimes, outgassing, atmospheric composition and planetary habitability.
Juno has transformed our view of Jupiter through major discoveries about its interior structure, origin, and evolution; atmospheric dynamics and composition; magnetic field and magnetosphere. Juno’s extended mission began in August 2021 and includes new objectives that reach beyond the planet itself to the Galilean satellites and Jupiter’s enigmatic ring system. This session invites observational and modeling results related to Juno’s results on Jupiter and the comparison to other giant planets, including exo-planetary systems. New results from Juno’s extended mission on Jupiter’s northern latitudes as well as the satellites and ring system are welcome.

The Gas and Ice Giant System Exploration session solicits abstracts on the scientific exploration of the Jovian, Kronian, Uranian and Neptunian systems with past and current missions (e.g. Juno, Cassini, remote observations), as well as presentations on future explorations missions and concepts (e.g. JUICE). This includes studies on their interiors, atmospheres, ionospheres, and magnetospheres, out to their ring systems and satellites, as well as the respective interactions between these regions.
We also explicitly welcome presentations on gas and ice giant exoplanet systems and encourage participation by colleagues more traditionally aligned with astronomy.
The session solicits contributions that report on nonthermal solar and planetary radio emissions. Coordinated multi-point observations from ground radio telescopes (e.g., LOFAR, LOIS, LWA1, URAN-2, UTR-2) and spacecraft plasma/wave experiments (e.g., Cassini, Cluster, Demeter, Galileo, Juno, Stereo, Ulysses and Wind) are especially encouraged. Presentations should focus on radiophysics techniques used and developed to investigate the remote magnetic field and the electron density in solar system regions, like the solar corona, the interplanetary medium and the magnetized auroral regions. Interest also extends to laboratory and experimental studies devoted to the comprehension of the generation mechanisms (e.g., cyclotron maser instability) and the acceleration processes (e.g., Alfven waves). Further preparations, evaluations, investigations, analyses of forthcoming space missions or nanosatellites (like BepiColombo, Juice, Solar Orbiter, Solar Probe, SunRISE, UVSQ-Sat, Inspire-Sat 7) are also welcome.

This session primarily focuses on the neutral atmospheres of terrestrial bodies other than the Earth. This includes not only Venus and Mars, but also exoplanets with comparable envelopes and satellites carrying dense atmospheres such as Titan or exospheres such as Ganymede. We welcome contributions dealing with processes affecting the atmospheres of these bodies, from the surface to the exosphere. We invite abstracts concerning observations, both from Earth or from space, modeling and theoretical studies, or laboratory work. Comparative planetology abstracts will be particularly appreciated.
The biosphere and geology of a planet are intrinsically interlinked. The geological habitat of Earth has driven the origin and evolution of life and biology has dramatically changed the planets surface and mineralogy over the last 4 billion years. In our Solar System, there are a broad range of planets and moons with potential habitable environments, and future missions will aim to determine if these ever had life or have life today. Planets orbiting other stars have different spectral types and metallicities and thus different starting bulk compositions which may impact the origin and evolution of life on those worlds. This session will examine the interplay of biology, and more broadly, habitability, from a planetary perspective.

Processes responsible for formation and development of the early Earth (> 2500Ma) are not well understood and strongly debated, reflecting in part the poorly preserved, altered, and incomplete nature of the geological record from this time.
In this session we encourage the presentation of new approaches and models for the development of Earth's early crust and mantle and their methods of interaction. We encourage contributions from the study of the preserved rock archive as well as geodynamic models of crustal and mantle dynamics so as to better understand the genesis and evolution of continental crust and the stabilization of cratons.
We invite abstracts from a large range of disciplines including geodynamics, geology, geochemistry, and petrology but also studies of early atmosphere, biosphere and early life relevant to this period of Earth history.

Analogue planetary research (APR) describes the development and testing
of space exploration strategies including scientific, technical,
operational, social and medical aspects in terrestrial environments
under simulated space or planetary conditions. As such, APR can be
performed in analogue planetary simulation, for example Lunar or Martian
analogue missions, where future crewed or robotic space exploration
missions are simulated and evaluated towards their performance.
With increasing popularity of analogue planetary simulations as
test-beds to develop and test technologies, techniques and operational
procedures for planetary missions in facilities such as HiSeas, MDRS,
LunAres, AATC, MMAARS or similar facilities, this session invites
contributions in the field of analogue planetary research including, but
not limited to:
- data analysis about sites for future exploration
- results and lessons-learned from Lunar / Martian analogue missions
- instruments development for analogue and space research
- field tests for space exploration hardware, software and techniques
- scientific contributions through analogue research
- geological field work during planetary simulations
- future analogue mission concepts
- transferring APR results into actual space exploration missions

Aeolian processes are active on various planetary surfaces throughout the Solar System and yield similar landforms across a wide range of spatial scales despite differences in atmospheric and surface properties. They are typically associated with the movement of sediments driven by an atmospheric flow but can also be controlled by other modes of matter transport such as ice sublimation. The combination of terrestrial and extra-terrestrial experiments and observations provides the opportunities as well as challenges for improving our fundamental theories and numerical models for better understanding of these aeolian environments. Innovations in instrumentation and experimental techniques continue to yield novel insights on Earth, while space missions and remote probes constantly deliver new and surprising evidence from aeolian environments on other planetary bodies. This session welcomes research on all aspects of aeolian processes and landforms, contemporary and ancient, on planetary surfaces across the Solar System.

Geomorphometry, a science of quantitative land surface analysis, gathers various mathematical, statistical and image processing techniques to quantify morphological, hydrological, ecological and other aspects of a land surface. The typical input to geomorphometric analysis is a square-grid representation of the land surface: a digital elevation model (DEM) or one of its derivatives. DEMs provide the backbone for many studies in Geo sciences, hydrology, land use planning and management, Earth observation and natural hazards.
One topic of active research concerns compromises between the use of global DEMs at 1-3 arc second, ~30-90 m grid spacing, and local LiDAR/structure from motion (SFM) elevation models at 1 m or finer grid spacing. Point clouds from LiDAR, either ground-based or from airborne vehicles, are a generally accepted reference tool to assess the accuracy of other DEMs. SFM data have a resolution comparable to LiDAR point clouds, but can cost significantly less to acquire for smaller areas. Globally available DEMS include the recently published Copernicus GLO-90 and GLO-30. This session provides an exciting forum to show the potential applications of this new DEM and its improvements over SRTM. We would like to investigate the tradeoff between the employment of the two kinds of data, and applications which can benefit from data at both (local and global) scales.
The improvements in the global DEMs, as well as the increasing availability of much finer resolution LiDAR and SFM DEMs, call for new analytical methods and advanced geo-computation techniques, necessary to cope with diverse application contexts. We aim at investigating new methods of analysis and advanced geo-computation techniques, including high-performance and parallel computing implementations of specific approaches.
Commercial applications of DEM data and of geomorphometric techniques can benefit important business sectors. Besides a proliferation of applications that can tolerate low accuracy geographical data and simple GIS applications, a large base of professionals use high-resolution, high-accuracy elevation data and high-performance GIS processing. We would like to survey and investigate professional, commercial and industrial applications, including software packages, from small enterprises to large companies, to ascertain how academic researchers and industry can work together.
Networking is crucial for scientists of all career stages for collaborations as well as for their personal growth and career pathways. Your scientific network can support you when struggling with everyday academic life, help with making career choices and give feedback on job applications/proposals/papers. Further, having a scientific network can provide new perspectives for your research while leading to interdisciplinary collaborations and new projects.
Building up an initial network can be challenging, especially outside of your research institution. As scientific conferences and social media platforms are evolving, the possibilities of academic networking are also changing. In this short course we will share tips and tricks on how to build, grow and maintain your scientific network. Additionally, panelist will talk about their own personal experiences. In a second part of the short course we will do a networking exercise. This short course is relevant to scientist who are starting to build/grow their network or want to learn more about networking in today’s scientific settings.

Finding funds can be challenging in academia, be it during PhD, or after that. A great proposal or just a great idea does not guarantee success, instead, it involves developing skills and exploring the paths which can lead to securing funds. It involves meticulous steps of evolving idea, proposal development, budget generation, and finally finding funding opportunities. In this course, early-career scientists, and faculty members with a wide range of backgrounds will provide guidance both in the research, and financial aspects of the proposal writing. The course is integrated with open Q&A which will provide participants to ask and seek advice from the experts. This course targets a wide range of audience ranging from graduate students to early-career scientists, but anyone with an interest in finding funds could participate

Visualisation of scientific data is an integral part of scientific understanding and communication. Scientists have to make decisions about the most effective way to communicate their results everyday. How do we best visualise the data to understand it ourselves? How do we best visualise our results to communicate with others? Common pitfalls can be overcrowding, overcomplicated plot types or inaccessible color schemes. Scientists may also get overwhelmed by the graphics requirements of different publishers, for presentations, posters etc. This short course is designed to help scientists improve their data visualization skills in a way that the research outputs would be more accessible within their own scientific community and reach a wider audience.
Topics discussed include:
- Choosing a plot type – keeping it simple
- Color schemes – which ones to use or not to use
- Creativity vs simplicity – finding the right balance
- Producing your figures – software and tools
- Figure files – publication ready resolutions
This course is organized by the Young Hydrologic Society (YHS), enabling networking and skill enhancement of early career researchers worldwide. Our goal is to help you make your figures more accessible by a wider audience, informative and beautiful. If you feel your graphs are complicated or not intuitive, we welcome you to join this short course.

The 2021-2022 Hunga Tonga-Hunga Ha'apai eruption in Tonga was among the largest of recent decades. The event was notable for its high intensity, generating a convective column that rapidly ascended well into the stratosphere; for the atmospheric pressure wave generated by the explosion, which was detected globally; and for generating a tsunami that was observable across Pacific Ocean shorelines. Following a series of preceding seismic and explosive events since December 2021, the sustained phase of the eruption on 15th January was relatively short lived, but the associated pressure wave and tsunami impacts were the most far-reaching since the eruption of Krakatau volcano in 1883. Tsunamis were recorded both locally and in the far-field, but their mechanism(s) remains uncertain; in the near field being from either (or both of) the collapsing eruption column or a phreatomagmatic explosion as the erupting mass mixed with sea water. In the far-field the tsunamis are possibly best explained by the massive atmospheric pressure wave, that is the first instrumentally recorded eruption-generated event of its type, which affected the entire global atmosphere and ionosphere, causing the observed infrasound waves and unusual long-period seismic resonances.
This interdisciplinary late-breaking session welcomes contributions from all disciplines involved in local and global observations of this eruption and its effects, including remote sensing observations and modeling as well as hazard assessment and estimation of damage and long-term consequences.
Glaciers and volcanoes interact in a number of ways, including instances where volcanic/geothermal activity alters glacier dynamics or mass balance, via subglacial eruptions or the deposition of supraglacial tephra. Glaciers can also impact volcanism, for example by directly influencing mechanisms of individual eruptions resulting in the construction of distinct edifices. Glaciers may also influence patterns of eruptive activity when mass balance changes adjust the load on volcanic systems, the water resources and hydrothermal systems. However, because of the remoteness of many glacio-volcanic environments, these interactions remain poorly understood.
In these complex settings, hazards associated with glacier-volcano interaction can vary from lava flows to volcanic ash, lahars, landslides, pyroclastic flows or glacial outburst floods. These can happen consecutively or simultaneously and affect not only the earth, but also glaciers, rivers and the atmosphere. As accumulating, melting, ripping or drifting glaciers generate signals as well as degassing, inflating/ deflating or erupting volcanoes, the challenge is to study, understand and ultimately discriminate these potentially coexisting signals. We wish to fully include geophysical observations of current and recent events with geological observations and interpretations of deposits of past events. Glaciovolcanoes also often preserve a unique record of the glacial or non-glacial eruptive environment that is capable of significantly advancing our knowledge of how Earth's climate system evolves.
We invite contributions that deal with the mitigation of the hazards associated with ice-covered volcanoes in the Arctic, Antarctic or globally, that improve the understanding of signals generated by ice-covered volcanoes, or studies focused on volcanic impacts on glaciers and vice versa. Research on recent activity is especially welcomed. This includes geological observations e.g. of deposits in the field or remote-sensing data, together with experimental and modelling approaches. We also invite contributions from any part of the world on past activity, glaciovolcanic deposits and studies that address climate and environmental change through glaciovolcanic studies. We aim to bring together scientists from volcanology, glaciology, seismology, geodesy, hydrology, geomorphology and atmospheric science in order to enable a broad discussion and interaction.

The Tethyan orogenic belt is one of the largest and most prominent collisional zones on Earth. The belt ranges from the Mediterranean in the west to Papua New Guinea in the east. It results from the subduction and closure of multiple basins of the Tethys Ocean and the subsequent collision of the African, Arabian and Indian continental plates with Eurasia. Its long-lasting geological record of the opening and closure of oceanic basins, the accretion of arcs and microcontinents, the complex interactions of major and smaller plates, and the presence of subduction zones at different evolutionary stages, has progressively grown as a comprehensive test site to investigate fundamental plate tectonics and geodynamic processes with multiple disciplines. Advances in a variety of fields provide a rich and growing set of constraints on the crust-lithosphere and mantle structure and their physical and chemical characteristics, as well as the tectonics and geodynamic evolution of the Tethyan orogenic belt.
We welcome contributions presenting new insights and observations derived from different perspectives, including geology (tectonics, stratigraphy, petrology, geochronology, geochemistry, and geomorphology), geophysics (seismicity, seismic imaging, seismic anisotropy, gravity), geodesy (GPS, InSAR), modelling (numerical and analogue), natural hazards (earthquakes, volcanism). In particular, we encourage the submission of trans-disciplinary studies, which integrate observations across a range of spatial and temporal scales to further our understanding of plate tectonics as a planetary process of fundamental importance.
The Arabian Plate recorded several plate reorganizations from the Neoproterozoic to present, including the Cadomian and Angudan orogenies, Late Paleozoic rifting and Alpine Orogeny. Active tectonics are framing the Arabian Plate and produce a variety of structures, including extensional structures related to rifting of the Red Sea and Gulf and Aden, strike-slip structures at the Dead Sea and Owen transform faults and compressive structures related to the Zagros-Makran convergence zone. The Arabian Peninsula contains the planet’s largest hydrocarbon reservoirs, owing to its geological history as Gondwana’s passive margin during the Permo-Mesozoic. Moreover, the Semail Ophiolite as the largest exposed ophiolite on Earth offers a unique example of large-scale obduction and overridden sedimentary basins. This and the spectacular outcrop conditions make the Arabian Peninsula an important and versatile study area. Ongoing research and new methods shed new light on, e.g., mountain building processes and its geomorphological expression as well as hydrocarbon development/migration.
We invite contributions that utilize structural, geophysical, tectonic, geochronological, geomorphological, sedimentary, geochemical/mineralogical, and field geological studies from the Arabian Peninsula and surrounding mountain belts and basins. These studies may include topics dealing with structures/basin analyses of any scale and from all tectonic settings ranging from the Neoproterozoic until today.
The Mediterranean region holds a plate boundary zone undergoing final closure between two major plates, Africa and Eurasia. The active tectonics and geodynamics of the Mediterranean region result from the interaction of subduction and collision processes, deformation of the slabs, mantle flow, and extrusion of crustal blocks. These geodynamic processes have a transient nature and their changes affect the regional tectonics.
This session focuses on two aspects of the Mediterranean recent active tectonics and geodynamics:
(1) how (active) geodynamic mechanisms define the current structure and recent evolution of Mediterranean Arc systems.
(2) how the surface deformation is accommodated, both on fault local scale (e.g. the seismic cycle and kinematics of active faults) and in the larger (e.g. regional kinematics and relation the surface deformation to the deeper processes).
We welcome contributions from a wide range of disciplines including, but not limited to seismology, tectonic geodesy, remote sensing, paleoseismology, tectonic geomorphology, active tectonics, structural geology, and geodynamic modeling.
We strongly encourage the contribution of early career researchers.
This session is formed by merging of TS sessions: "Active tectonics and geodynamics of the Eastern Mediterranean" & "Recent geodynamic evolution and active tectonics of Mediterranean Arcs"

We invite contributions that address the present and past structure and dynamics of the Alpine orogens of the Mediterranean area. Since 2015, the international AlpArray mission and related projects have generated a plethora of new data to test the hypothesis that mantle circulation driving plates’ re-organization during collision has both immediate and long-lasting effects on the structure, motion, earthquake distribution and landscape evolution in mountain belts. Links between Earth’s surface and mantle have been forged by integrating 3D geophysical imaging of the entire crust-mantle system, with geologic observations and modelling to provide a look both backwards and forwards in time, the 4th dimension. This integrated 4D approach, initially focused on the Alps, has been expanded to the Pannonian-Carpathian and Adriatic areas, and now includes the Apennines and Dinarides. A new initiative, AdriaArray, is underway to shed light on plate-scale deformation and orogenic processes in this dynamic part of the Alpine-Mediterranean chain. The forthcoming Drilling the Ivrea-Verbano zonE (DIVE) project bridges new observations across scales and investigates the evolution of the continental lower crust. This session provides an interdisciplinary platform for highlighting the newest results and open questions of the aforementioned projects, regions and themes.

Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

Recently, there have been significant breakthroughs in the use of fiber-optic sensing techniques to interrogate cables at high precision both on land and at sea as well as in boreholes and at the surface. Laser reflectometry using both fit-to-purpose and commercial fiber-optic cables have successfully detected a variety of signals including microseism, local and teleseismic earthquakes, volcanic events, ocean dynamics, etc. Other laser-based techniques can be used to monitor distributed strain, temperature, and even chemicals at a scale and to an extent previously unattainable with conventional geophysical methods.
We welcome any contributions to recent development in the fields of applications, instrumentation, and theoretical advances for geophysics with fiber-optic sensing techniques. These may include - but are not limited to - application of fiber-optic cables or sensors in seismology, geodesy, geophysics, natural hazards, oceanography, urban environment, geothermal application, etc. with an emphasis on laboratory studies, large-scale field tests, and modeling. We also encourage contributions on data analysis techniques, machine learning, data management, instruments performances and comparisons as well as new experimental field studies.
New developments in seismic instrumentation enable highly precise direct point observations of seismic ground motion and its spatial gradients not only in permanent but also in temporary seismic experiments. Considerable improvements in optical and atom interferometry enable new concepts for inertial rotation, translational displacement and acceleration sensing.
Applications of the resulting new type of data range from seismic source and wavefield characterization with single point observations in harsh environments to the correction of tilt effects, e.g. for high performance seismic isolation facilities.
We invite contributions on novel measurement techniques and experiment design, on theoretical advances to the seismic wavefield gradient analysis, as well as on all aspects of applications of ground motion gradient observations in seismology, geodesy, planetary exploration, gravitational wave detection and fundamental physics.

The number and quality of seismic stations and networks continually improves in Europe and worldwide. Current state-of-the-art permanent seismic monitoring means dense deployments of modern broadband velocity and acceleration sensors, often co-located, writing on 24- or 26-bit digitisers, with continuous real-time streaming to data centers. Technological improvements have been accompanied by community developments of standards, protocols, strategies and software to ease and homogenise data acquisition, archival, dissemination and processing. The integration of new data types like those generated by DAS systems, large-N low-cost instrumentation, OBS, GNSS, gravity, infrasound instruments, etc. poses challenges to the existing strategies for data management from acquisition to dissemination. Optimising performance, improving data and metadata quality, enhancing waveform services and products require continued efforts by seismic network operators and managers. In this session we welcome contributions from all aspects of seismic network deployment, operation and management. This includes site selection; equipment testing and installation; planning and telemetry; policies for redundancy in data acquisition; processing and archiving; data and metadata QC; data management and dissemination policies; technical and scientific products; integration of new datasets and communities.
This session is promoted by the EGU sub-division “Seismic Instrumentation & Infrastructure” and ORFEUS (http://orfeus-eu.org/). ORFEUS coordinates waveform seismology in Europe through the collection, archival and distribution (http://www.orfeus-eu.org/data/eida/; http://www.orfeus-eu.org/data/strong/) of seismic waveform data, metadata and closely-related derived products. This session facilitates seismological data discovery and promotes open and FAIR data policies.

Continues monitoring of infrastructure systems are essential to ensure a reliable movement of people and goods, which involves in the economy growth and human interaction. The wide variety of instruments available allows diverse applications to increase data availability for a better understanding of geotechnical surroundings which are directly linked to the safe operation of infrastructures to prevent catastrophise such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding and even wildfires close to the highways. Understanding mentioned events are vital to provide a safe infrastructure in extreme climate conditions. This session focus on the application of geosciences and geophysical instrumentation including sensors on the infrastructures monitoring and data analysis from critical infrastructures (e.g., roadways, railway system, bridges, tunnels, water supply, underground utilities, electrical grids, and other embedded facilities in cities). The session aims to increase knowledge on geo-infrastructure management to overcome future challenges associated with the societal and human interaction, present advance knowledge research and novel approaches from various disciplines with a vibrant interaction to economy and human-interaction studies to provide an efficient infrastructure management system. The session is considered inter-and transdisciplinary (ITS) session. The applications and topics include but are not limited to: (1) Advance knowledge of the destructive and non-destructive geoscience and geophysical techniques including contactless and non-contactless techniques such as sensors. (2) Intelligent data analysis approaches to analyse accurate and precise interpretation of big data sets driven from various technologies (e.g., computer vision and image, and signal processing). (3) Influence of the surrounding areas on infrastructure management systems linked to natural events such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding, wildfires and extreme weather condition. (4) Continuous real-time monitoring to provide smart tools such as an integration of geosciences data with BIM models, Internet of Things, digital twins, robotic monitoring, artificial intelligence, automation systems based on machine learning and computational modelling for better decision-making for infrastructure owner/operators. (5) Human-interaction computer-based aided to generate reliable infrastructures.
The International Monitoring System (IMS) of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) senses the solid Earth, the oceans and the atmosphere with a global network of seismic, infrasound, and hydroacoustic sensors as well as detectors for atmospheric radioactivity. The primary purpose of the IMS data is for nuclear explosion monitoring regarding all aspects of detecting, locating and characterizing nuclear explosions and their radioactivity releases. On-site verification technologies apply similar methods on smaller scales as well as geophysical methods such as ground penetrating radar and geomagnetic surveying with the goal of identifying evidence for a nuclear explosion close to ground zero. Papers in this session address advances in the sensor technologies, new and historic data, data collection, data processing and analysis methods and algorithms, uncertainty analysis, machine learning and data mining, experiments and simulations including atmospheric transport modelling. This session also welcomes papers on applications of the IMS and OSI instrumentation data. This covers the use of IMS data for disaster risk reduction such as tsunami early warning, earthquake hazard assessment, volcano ash plume warning, radiological emergencies and climate change related monitoring. The scientific applications of IMS data establish another large range of topics, including acoustic wave propagation in the Earth crust, stratospheric wind fields and gravity waves, global atmospheric circulation patterns, deep ocean temperature profiles and whale migration. The use of IMS data for such purposes returns a benefit with regard to calibration, data analysis methods and performance of the primary mission of monitoring for nuclear explosions.

Interferometric techniques turn seismic networks into continuous observation devices for (time-varying) Earth structure, volcanic and hydrologic processes, ocean - solid Earth interactions and many more phenomena. Increasingly, seismic interferometry is applied to signals beyond ocean microseismic noise, such as earthquake coda and anthropogenic seismic signals.
Great strides have been taken in obtaining high-resolution images of seismic velocity and other properties, in observing and quantifying the sources of various ambient noise wave types, and in interpreting seismic property variations. Current challenges include the interpretation of signals from less-than-ideally situated sources, e.g. in the context of traffic noise interferometry or ambient noise body waves from localized storms; the interpretation of ambient noise amplitudes for elastic effects and anelastic attenuation; and the spatial localization of seismic property changes.
This session offers a broad space for discussing recent advances in ambient noise seismology and seismic interferometry. We invite abstracts on theoretical and numerical developments as well as novel applications. Topics may include, but are not limited to, studies of ambient seismic sources; ocean wave quantification through ambient noise; urban seismic noise; interferometric imaging; monitoring subsurface properties and quantifying the response of seismic velocity to various stresses and strains; studies of the spatial sensitivity for imaging and monitoring under various source conditions; quantification of site effects, amplification and attenuation; improvements in processing and retrieval of high-quality interferometry observations, and interdisciplinary applications of seismic interferometry.

In the last two decades, the number of high quality seismic instruments being installed around the world has grown exponentially and probably will continue to grow in the coming decades. This led to a dramatic increase in the volume of available seismic data and pointed out the limits of the current standard routine seismic analysis, often performed manually by seismologists. Exploiting this massive amount of data is a challenge that can be overcome by using new generation, fully automated and noise-robust seismic processing techniques. In the last years, waveform-based detection, location, and source-parameter estimation methods have grown in popularity and their application have dramatically improved seismic monitoring capability. Moreover, machine learning and deep learning techniques, which are dedicated methods for data-intensive applications, are showing promising results in seismicity characterization applications opening new horizons for the development of innovative, fully automated and noise-robust seismic analysis methods. Such techniques are particularly useful when working with data sets characterized by large numbers of weak events with low signal-to-noise ratio, such as those collected in induced seismicity, seismic swarms and volcanic monitoring operations. This session aims on bringing to light new methods and tools and also optimizations of existing approaches that make use of High Performance Computing resources (CPU, GPU) and can be applied to large data sets, either retro-actively or in (near) real-time, to characterize seismicity (i.e. perform detection, location, magnitude and source-mechanism estimation) at different scales and in different environments. We thus encourage contributions that demonstrate how the proposed methods help improve our understanding of earthquake and/or volcanic processes.

From the real-time integration of multi-parametric observations is expected the major contribution to the development of operational t-DASH systems suitable for supporting decision makers with continuously updated seismic hazard scenarios. A very preliminary step in this direction is the identification of those parameters (seismological, chemical, physical, biological, etc.) whose space-time dynamics and/or anomalous variability can be, to some extent, associated with the complex process of preparation of major earthquakes.
This session wants then to encourage studies devoted to demonstrate the added value of the introduction of specific, observations and/or data analysis methods within the t-DASH and StEF perspectives. Therefore, studies based on long-term data analyses, including different conditions of seismic activity, are particularly encouraged. Similarly welcome will be the presentation of infrastructures devoted to maintain and further develop our present observational capabilities of earthquake related phenomena also contributing in this way to build a global multi-parametric Earthquakes Observing System (EQuOS) to complement the existing GEOSS initiative.
To this aim this session is not addressed just to seismology and natural hazards scientists but also to geologist, atmospheric sciences and electromagnetism researchers, whose collaboration is particular important for fully understand mechanisms of earthquake preparation and their possible relation with other measurable quantities. For this reason, all contributions devoted to the description of genetic models of earthquake’s precursory phenomena are equally welcome.

This session covers the broad field of earthquake source processes, and
includes the topics of imaging the rupture kinematics and simulating
earthquake dynamics using numerical methods, to develop a deeper
understanding of earthquake source physics. We also invite presentation
that link novel laboratory experiments to earthquake dynamics, and
studies on earthquake scaling properties.
Earthquake sources are imaged using seismic data and surface deformation
measurements (e.g.GPS and InSAR) to estimate rupture properties on
faults and fault systems. Each data set and each method has its strength
and limitations in the context of the source-inversion problem, but the
uncertainties are often not well quantified and the robustness of the
source models not well known.
The session invites contributions that address the source-inversion
problem and provide new methods, innovative applications, and
thought-provoking new ideas. Contributions are welcome that make use of modern
computing paradigms and infrastructure to tackle large-scale forward
simulation of earthquake process, but also inverse modeling to retrieve
the rupture process with proper uncertainty quantification.
Earthquake source imaging, numerical modeling of rupture dynamics, and
source-scaling relations help to understand earthquake source processes.
Furthermore, new numerical modeling approaches for multi-scale
earthquake physics, including earthquake-cycle simulations, may include
fault-zone evolution and even target seismic hazard assessment. The
question that these lines of research are targeting are profound and of
first-order socio-economic relevance:
Which first-order physical processes control, at a given space-time
scale, the macroscopic evolution of dynamic rupture and its seismic
radiation? Is the physics of fault rupture the same for large and small
earthquakes? How can modern earthquake hazard assessment profit from a
deeper understanding of rupture dynamics? Which source processes need to
be considered to better understand, and then model, tsunami generation,
triggering phenomena, induced seismicity and earthquake cycles?
Within this framework our session also provides a forum to discuss case
studies of kinematic or dynamic source modeling of recent significant
earthquakes.

Continental rifting is a complex process spanning from the inception of extension to continental rupture or the formation of a failed rift. This session aims at combining new data, concepts and techniques elucidating the structure and dynamics of rifts and rifted margins. We invite submissions highlighting the time-dependent evolution of processes such as: initiation and growth of faults and ductile shear zones, tectonic and sedimentary history, magma migration, storage and volcanism, lithospheric necking and rift strength loss, influence of the pre-rift lithospheric structure, rift kinematics and plate motion, mantle flow and dynamic topography, as well as break-up and the transition to sea-floor spreading. We encourage contributions using multi-disciplinary and innovative methods from field geology, geochronology, geochemistry, petrology, seismology, geodesy, marine geophysics, plate reconstruction, or numerical or analogue modelling. Special emphasis will be given to presentations that provide an integrated picture by combining results from active rifts, passive margins, failed rift arms or by bridging the temporal and spatial scales associated with rifting.

Subduction drives plate tectonics, generating the major proportion of subaerial volcanism, releasing >90% seismic moment magnitude, forming continents, and recycling lithosphere. Numerical and laboratory modeling studies have successfully built our understanding of many aspects of the geodynamics of subduction zones. Detailed geochemical studies, investigating compositional variation within and between volcanic arcs, provide further insights into systematic chemical processes at the slab surface and within the mantle wedge, providing constraints on thermal structures and material transport within subduction zones. However, with different technical and methodological approaches, model set-ups, inputs, and material properties, and in some cases conflicting conclusions between chemical and physical models, a consistent picture of the controlling parameters of subduction-zone processes has so far not emerged.
This session aims to follow subducting lithosphere on its journey from the surface down into the Earth's mantle and to understand the driving processes for deformation and magmatism in the over-riding plate. We aim to address topics such as: subduction initiation and dynamics; changes in mineral breakdown processes at the slab surface; the formation and migration of fluids and melts at the slab surface; primary melt generation in the wedge; subduction-related magmatism; controls on the position and width of the volcanic arc; subduction-induced seismicity; mantle wedge processes; the fate of subducted crust, sediments and volatiles; the importance of subducting seamounts, LIPs, and ridges; links between near-surface processes and slab dynamics and with regional tectonic evolution; slab delamination and break-off; the effect of subduction on mantle flow; and imaging subduction zone processes.
With this session, we aim to form an integrated picture of the subduction process, and invite contributions from a wide range of disciplines, such as geodynamics, modeling, geochemistry, petrology, volcanology, and seismology, to discuss subduction zone dynamics at all scales from the surface to the lower mantle, or in applications to natural laboratories.

Since approximately 90% of the seismic moment released by earthquakes worldwide occurs near subduction zones, it is crucial to improve our understanding of seismicity and the associated seismic hazard in these regions. Seismicity in subduction zones takes many forms, ranging from relatively shallow seismicity on outer-rise and splay faults and the megathrust to intermediate-depth (70-300 km) and deep events (>300 km). While most research on subduction earthquakes focuses on the megathrust, all these different seismic events contribute to the seismic hazard of a subduction zone.
This session aims to integrate our knowledge on different aspects of subduction zone seismicity to improve our understanding of the interplay between such events and their relationship to subduction dynamics. We particularly invite abstracts that use geophysical and geological observations, laboratory experiments and/or numerical models to address questions such as: (1) What are the mechanisms behind intraplate seismicity? (2) How do outer-rise and splay fault seismicity relate to the seismogenic behaviour of the megathrust? (3) How do slab dynamics influence both shallow and deep seismicity?

Tsunamis can produce catastrophic damage on vulnerable coastlines, essentially following major earthquakes, landslides, extreme volcanic activity or atmospheric disturbances. After the disastrous tsunamis in 2004 and 2011, tsunami science has been continuously growing and expanding its scope to new fields of research in various domains, and also to regions where the tsunami hazard was previously underestimated.
The spectrum of topics addressed by tsunami science nowadays ranges from the “classical” themes, such as analytical and numerical modelling of different generation mechanisms (ranging from large subduction earthquakes to local earthquakes generated in tectonically complex environments, from subaerial/submarine landslides to volcanic eruptions and atmospheric disturbances), propagation and run-up, hazard-vulnerability-risk assessment, especially with probabilistic approaches able to quantify uncertainties, early warning and monitoring, to more “applied” themes such as the societal and economic impact of moderate-to-large events on coastal local and nation-wide communities, as well as the present and future challenges connected to the global climate change.
This session, co-organized with OS4, SM4, GMPV9, GM and AS, welcomes multidisciplinary as well as focused contributions covering any of the aspects mentioned above, encompassing field data, geophysical models, regional and local hazard-vulnerability-risk studies, observation databases, numerical and experimental modeling, real time networks, operational tools and procedures towards a most efficient warning, with the general scope of improving our understanding of the tsunami phenomenon, per se and in the context of the global change, and our capacity to build safer and more resilient communities.

Tectonic faults accommodate plate motion through various styles of seismic and aseismic slip spanning a wide range of spatiotemporal scales. Understanding the mechanics and interplay between seismic rupture and aseismic slip is central to seismotectonics as it determines the seismic potential of faults. In particular, unraveling the underlying physics controlling these styles of deformation bears a great deal in earthquakes hazards mitigation especially in highly urbanized regions. We invite contributions from observational, experimental, geological and theoretical studies that explore the diversity and interplay among seismic and aseismic slip phenomena in various tectonic settings, including the following questions: (1) How does the nature of creeping faults change with the style of faulting, fluids, loading rate, and other factors? (2) Are different slip behaviors well separated in space, or can the same fault areas experience different failure modes? (3) Is there a systematic spatial or temporal relation between different types of slip?

One of the key challenges in earthquake geology is the characterization of the spatial distribution of fault-slip and its partitioning during the coseismic, interseismic, and post-seismic periods. We now have new approaches and techniques for validating the assumption that repeated seismic cycles accommodate the long-term tectonic strain and for disentangling such a complex strain partitioning in both time and space. In fact, the temporal and spatial slip accumulation for an active fault is essential to understand the hazard posed by the fault. As a matter of fact, destructive earthquakes are infrequent along any active fault and this is an inherent limitation to knowledge towards reconstructing the seismic cycle. For example, the occurrence of the 2021 Alaska earthquake Mw 8.2 within the rupture zone of the Mw 8.2 1938 Alaska earthquake, and 2021 Haiti earthquake Mw 7.2 within the same fault zone of the 2010 earthquake Mw 7.0 (which claimed 300,000 lives), reflects how much the characterization of the seismic cycle and earthquakes’ recurrence is critical for cities and regions which are under the constant seismic threat.
Modern techniques such as Remote Sensing, Geodesy, Geomorphology, Paleoseismology, and Geochronology play a vital role in constraining part of or full seismic cycles, with increased accuracy and temporal coverage of the long-term deformation. To fully understand these observations there is a need for a better understanding and integration of such techniques to be applied across different fault systems, globally.
The goal of this session is to bring together innovative approaches and techniques, to take a comprehensive look at the earthquake cycle for plate boundary fault systems to fault systems sitting far away from the plate boundary.
In recent years, the application of shear-wave seismic methods for shallow investigations (<500 m depth) has become more and more popular. Shear waves are utilized for, e.g., structural imaging, geotechnical investigation, and elastic parameter studies, and their evaluation comprises techniques, such as reflection imaging, attribute analysis, converted
wave- and VP/VS analysis, travel-time tomography, or full waveform inversion. For shallow studies particularly, shear-wave techniques have a great potential, since near-surface resolution benefits from low shear-wave velocities. Furthermore, the shear wave reflection signals can easily be extracted from the recorded wave-field at small offsets, which makes shear-wave reflection surveying more cost efficient, compared to P-waves.
Shear-wave surveys can further benefit from sealed ground conditions due to the suppression of Love waves, and, thus, are predesignated for the application in urban areas. Shallow shear-wave and multicomponent seismic methods undergo a continuous technical development of specialized sources and customized equipment, including innovative concepts for acquisition and data processing (e.g. interferometry, converted waves, horizontal-to-vertical-spectral-
ratio). Exciting as well as recording several directions of the ground motion simultaneously (we refer to multicomponent seismic) is also beneficial, since it allows separating vertically (SV) and horizontally (SH) polarized shear wave-fields, which is mandatory, e.g., for 3-D surveys. Wave conversion and scattering effects can be distinguished, and differently polarised shear waves simplify the detection of seismic anisotropy.
This session shall promote the exchange of experience using shear waves in shallow applications and trigger discussions about their potential in seismic imaging. Combined studies integrating P-waves are highly appreciated. With the focus on shear body waves, we invite, but do not restrict, contributions to technical development, data analysis, seismic
processing, and case studies. The latter may comprise, e.g., (a) geotechnical studies, such as examination of soil rigidity or dams, (b) exploration of structures, such as volcanic craters or groundwater resources, (c) analysis of potential geo-hazards like faults, quick clays, landslides, sinkholes, and subrosion features, and (d) more exotic applications, such as the exploration of glacier ice thickness, permafrost or other planets.
Geophysical imaging techniques are widely used to characterize structures and processes in the shallow subsurface. Methods include active imaging using seismic, (complex) electrical resistivity, electromagnetic, and ground-penetrating radar methods, as well as passive monitoring based on ambient noise or electrical self-potentials. Advances in experimental design, instrumentation, data acquisition, data processing, numerical modelling, and inversion constantly push the limits of spatial and temporal resolution. Despite these advances, the interpretation of geophysical images often remains ambiguous. Persistent challenges addressed in this session include optimal data acquisition strategies, (automated) data processing and error quantification, appropriate spatial and temporal regularization of model parameters, integration of non-geophysical measurements and geological realism into the imaging process, joint inversion, as well as the quantitative interpretation of tomograms through suitable petro-physical relations.
In light of these topics, we invite submissions concerning a broad spectrum of near-surface geophysical imaging methods and applications at different spatial and temporal scales. Novel developments in the combination of complementary measurement methods, machine learning, and process-monitoring applications are particularly welcome.

Imaging both fluid-filled fault networks and surrounding heterogeneous crust with geophysical methods is especially challenging. In these settings, fluids interact with deformation-induced seismic sources, influencing both nucleation and development of seismic sequences.
Imaging and characterizing both seismogenic structures and elastic and anelastic properties of the surrounding medium is key to understanding wider tectonic and small-scale deformation processes. Understanding the geometry and kinematics of crustal-scale faults from field observations is also critical for many green-energy applications (e.g., geothermal energy, CO2 storage, mining for minerals important for battery production). This session aims to provide an overview of techniques and applications aimed at characterizing both active and ancient seismogenic fault networks at local and regional scales.
In this session we aim to bring together passive and active-source seismologists to discuss new studies that image and characterize seismically active and ancient faults and fault networks. We welcome contributions from velocity tomography, attenuation tomography (coda, t* method, direct wave attenuation), source imaging and characterization (absolute and relative location techniques, focal mechanism and stress drop analysis, …), active-source seismic techniques (reflection, refraction, integrated drilling data, …), along with multidisciplinary studies. We particularly welcome contributions from early-career researchers and those using novel techniques (e.g., data mining and machine learning).
Active and passive seismological methods are largely employed for characterizing the crustal structure in tectonic or volcanic settings, from the near-surface down to several kilometers of depth and at a global scale.
Active seismic methods (mainly reflection and refraction seismic) have shown to be particularly effective in providing images of the crust, in terms of velocities, seismic tomography, reflection coefficient, and seismic attributes. Although they are commonly used for mineral prospecting purposes, these techniques also provide a fundamental tool for studying the structural and stratigraphic patterns in different geological settings. Nonetheless, active seismic methods show several issues and limitations, mainly due to the cost and availability of the instruments, the difficulties in exploring remote areas, and the loss in resolution with depth.
In this perspective, a fruitful synergy can arise from the combination of active and passive seismic methods, which use earthquakes or ambient noise as a source. For instance, passive seismic is fundamental to detect seismogenic crustal regions, and their attitude to release seismic energy with frequent low-energy earthquakes or few strong events, by studying the b-value of the Gutenberg & Richter Frequency-Magnitude Distribution. Such information could be compared to some extent with the seismo-stratigraphic and structural model inferred from the analysis of active seismic data, for a deeper understanding of the crustal structure.
As a final issue, other geophysical data (e.g. gravimetric, magnetic, or geo-electric) could also provide further useful information, to better constrain the interpretation of seismological data.
Contributions to the session may include challenging applications, where the joint inversion and interpretation of both active and passive seismic data, corroborated by the results deriving from other methodologies, are employed to shed light on not-straightforward complexities in different geological contexts.
Cratons form the ancient, stable cores of most of the Earth’s continents. Knowledge about the present-day architecture of cratons is the key to understand the evolution of continental plates. In addition to that, cratons concentrate many economically relevant mineral deposits, which are indispensable for a modern society. For many cratonic regions however, little is still known about the present-day lithospheric structure and how it evolved since the Archean, mainly due to their remoteness and harsh local environmental conditions. Ongoing data acquisition, as well as the usage and optimization of
remote and passive techniques have shed new light on the lithospheric architecture of cratonic regions. Recent advancements across several disciplines show that cratons are more varied and fragmented than previously assumed, which has strong implications for geodynamic interactions with the convective mantle and long-term stability.
In this session, we welcome contributions across different scales that describe the cratonic lithosphere and its evolution with time, up to the dawn of plate tectonics. We aim to address topics like: characterization and evolution of cratonic crust and lithosphere; coupling between cratonic crust and mantle; mechanisms to form, maintain and destroy cratonic roots; craton-plume interaction; the role of cratons in supercontinent configurations; connection of cratons to mineral deposits.
We would like to raise discussions within a multidisciplinary session and therefore welcome contributions across a wide range of disciplines, including, but not limited to geodynamics, geology, tectonics, seismology, gravity, geochemistry, petrology, as well as joint approaches.

The geological processes that we infer from observations of the Earth’s surface, together with the landscape features are direct consequences of the dynamic Earth, and in particular, of the interaction between tectonic plates. Seismological studies are key for unraveling the present structure and fabric of the lithosphere and the asthenosphere. However, interdisciplinary work is required to fully understand the underlying processes and how features such as anisotropies in the crust, lithospheric mantle or the asthenosphere evolved through time and how they are related. Here we want to gather those studies focusing on seismic anisotropy and deformation patterns that can successfully improve our knowledge of the processes, leading to the observed present geometries (of the crust and the upper mantle). The main goal of the session is to establish closer links between seismological observations and process-oriented modelling studies to demonstrate the potential of different methods, and to share ideas of how we can collaboratively study upper mantle structure, and how the present-day fabrics of the lithosphere relates to the contemporary deformation processes and ongoing dynamics within the asthenospheric mantle.
Contributions from studies employing seismic anisotropy observations, tomography and waveform modeling, geodetic data, numerical and analogue modelling are welcome.

Many regions of the Earth, from crust to core, exhibit anisotropic fabrics which can reveal much about geodynamic processes in the subsurface. These fabrics can exist at a variety of scales, from crystallographic orientations to regional structure alignments. In the past few decades, a tremendous body of multidisciplinary research has been dedicated to characterizing anisotropy in the solid Earth and understanding its geodynamical implications. This has included work in fields such as: (1) geophysics, to make in situ observations and construct models of anisotropic properties at a range of depths; (2) mineral physics, to explain the cause of some of these observations; and (3) numerical modelling, to relate the inferred fabrics to regional stress and flow regimes and, thus, geodynamic processes in the Earth. The study of anisotropy in the Solid Earth encompasses topics so diverse that it often appears fragmented according to regions of interest, e.g., the upper or lower crust, oceanic lithosphere, continental lithosphere, cratons, subduction zones, D'', or the inner core. The aim of this session is to bring together scientists working on different aspects of anisotropy to provide a comprehensive overview of the field. We encourage contributions from all disciplines of the earth sciences (including mineral physics, seismology, magnetotellurics, geodynamic modelling) focused on anisotropy at all scales and depths within the Earth.
Geophysical and in-situ measurements offer important baseline datasets, as well as validation for modelling and remote sensing products. They are used to advance our understanding of firn, ice-sheet and glacier dynamics, sea ice processes, changes in snow cover and snow properties, snow/ice-atmosphere-ocean interactions, permafrost degradation, geomorphic mechanisms and changes in englacial and subglacial condition.
In this session we welcome contributions related to a wide spectrum of methods, including, but not limited to, advances in radioglaciology, active and passive seismology, geoelectrics, acoustic sounding, fiber-optic sensing, GNSS reflectometry, signal attenuation and time delay techniques, cosmic ray neutron sensing, ROV and drone applications, and electromagnetic methods. Contributions could be related to field applications, new approaches in geophysical or in-situ survey techniques, or theoretical advances in data analysis processing or inversion. Case studies from all parts of the cryosphere such as snow and firn, alpine glaciers, ice sheets, glacial and periglacial environments, permafrost, or sea ice, are highly welcome.
The focus of the session is to compare experiences in the application, processing, analysis and interpretation of different geophysical and in-situ techniques in these highly complex environments. We have been running this session for nearly a decade and it always produces lively and informative discussion. This session is offered as a fully hybrid vPICO: an engaging presentation format in which all authors will present their research orally as a quick-fire 2-minute overview, and then further present and discuss their research.

We invite contributions from various geophysical, geodynamic, geological, and geochemical studies, as well as from numerical modeling, which address the questions how various plate tectonics and mantle dynamics processes modify the lithosphere structure, control ore deposits, and how these processes changed during the Earth's evolution.

Earthquake swarms are characterized by a complex temporal evolution and a delayed occurrence of the largest magnitude event. In addition, seismicity often manifests with intense foreshock activity or develops in more complex sequences where doublets or triplets of large comparable magnitude earthquakes occur. The difference between earthquake swarms and these complex sequences is subtle and usually flagged as such only a posteriori. This complexity derives from aseismic transient forcing acting on top of the long-term tectonic loading: pressurization of crustal fluids, slow-slip and creeping events, and at volcanoes, magmatic processes (i.e. dike and sill intrusions or magma degassing). From an observational standpoint, these complex sequences in volcanic and tectonic regions share many similarities: seismicity rate fluctuations, earthquakes migration, and activation of large seismogenic volume despite the usual small seismic moment released. The underlying mechanisms are local increases of the pore-pressure, loading/stressing rate due to aseismic processes (creeping, slow slip events), magma-induced stress changes, earthquake-earthquake interaction via static stress transfer or a combination of those. Yet, the physics behind such processes and the ultimate reasons for the occurrence of swarm-like rather than mainshock-aftershocks sequences, is still far beyond a full understanding.
This session aims at putting together studies of swarms and complex seismic sequences driven by aseismic transients in order to enhance our insights on the physics of such processes. Contributions focusing on the characterization of these sequences in terms of spatial and temporal evolution, scaling properties, and insight on the triggering physical processes are welcome. Multidisciplinary studies using observation complementary to seismological data, such as fluid geochemistry, deformation, and geology are also welcome, as well as laboratory and numerical modeling simulating the mechanical condition yielding to swarm-like and complex seismic sequences.

Numerous cases of induced/triggered seismicity associated with anthropogenic activity resulting either directly or indirectly from injection/extraction related to geo-resources exploration have been reported in the last decades. Induced earthquakes felt by the general public can often negatively affect public perception of geo-energies and may hinder future geo-energy development. Furthermore, large earthquakes may jeopardize wellbore stability and damage surface infrastructure. Thus, monitoring and modeling processes leading to fault slip, either seismic or aseismic, are critical to developing effective and reliable forecasting methodologies during deep underground exploitation. The complex interaction between injected fluids, subsurface geology, stress interactions, and resulting fault slip requires an interdisciplinary approach to understand the triggering mechanisms and may require taking coupled thermo-hydro-mechanical-chemical processes into account.
In this session, we invite contributions from research aimed at investigating the interaction of the above processes during exploitation of underground resources, including hydrocarbon extraction, wastewater disposal, geothermal energy exploitation, hydraulic fracturing, gas storage and production, mining, and reservoir impoundment for hydro-energy. We particularly encourage novel contributions based on laboratory and underground near-fault experiments, numerical modeling, the spatio-temporal relationship between seismic properties, injection/extraction parameters, and/or geology, and fieldwork. Contributions covering both theoretical and experimental aspects of induced and triggered seismicity at multiple spatial and temporal scales are welcome.

Volcanic islands are simultaneously some of the tallest and fastest-forming geological features on Earth and constitute the site of significant geohazards ranging from volcanic eruptions, earthquakes, landslides, and tsunamis. Ocean island volcanoes are also some of the most enigmatic features in our planet, as their genesis is still not satisfactorily explained by conventional plate tectonics. The scientific community faces several challenges in studying volcanic islands, particularly in what regards processes taking place at depth. There is still a need to densify seismic networks in volcanic islands, using both land- and seafloor-based stations, to record the signals associated with volcanic and tectonic processes and automatically or manually detect and classify those signals. 3D images from the shallow crust to the deep mantle are crucial to unravel the geodynamic processes behind the generation of volcanism. More accurate quantification of temporal changes in the volcanic systems will help in the forecasting of potential eruptions and the monitoring of existing ones. On top of that, the presence of geothermal systems and induced seismicity from industrial exploration are also critical challenges in volcanic islands due to the system's complexity.
Considering the enormous diversity of interactions in volcanic islands, we welcome contributions from a wide range of studies including: seismo-volcanic monitoring and tracking of magma movements; characterization and location of volcanic tremor; 3D and 4D seismic imaging, including attenuation tomography; seismic ambient noise monitoring; machine learning to detect and classify volcanic earthquakes; active source studies to characterize volcanic flanks and landslides; induced and triggered seismicity in geothermal systems; and seismic sources.

Over the past few years, major technological advances significantly increased both the spatial coverage and frequency bandwidth of multi-disciplinary observations at active volcanoes. Networks of instruments, both ground- and satellite-based, now allow for the quantitative measurement of geophysical responses, geological features and geochemical emissions, permitting an unprecedented, multi-parameter vision of the surface manifestations of mass transport beneath volcanoes. Furthermore, new models and processing techniques have led to innovative paradigms for inverting observational data to image the structures and interpret the dynamics of volcanoes. In particular, machine learning, a type of AI in which computers learn from data, is gaining importance in volcanology, not only for monitoring purposes (i.e., in real-time) but also for later hazards analysis (e.g. modelling tools).
Within this context, this session aims to bring together a multidisciplinary audience to discuss the most recent innovations in volcano imaging and monitoring, and to present observations, methods and models that increase our understanding of volcanic processes.
We welcome contributions (1) related to methodological and instrumental advances in geophysical, geological and geochemical imaging of volcanoes, (2) to explore new knowledge provided by these studies on the internal structure and physical processes of volcanic systems, and (3) to investigate the potential of machine learning techniques to process multispectral satellite data for developing a better understanding of volcanic hazards.
We invite contributors from all geophysical, geological and geochemical disciplines: seismology, electromagnetics, geoelectrics, gravimetry, magnetics, muon tomography, volatile measurements and analysis. The session will include in-situ monitoring and high- resolution remote sensing studies that resolve volcanic systems ranging from near-surface hydrothermal activity to deep magma migration.

The Fagradalsfjall eruption on the Reykjanes Peninsula of Iceland started on 19 March 2021. It provides a unique opportunity to study all aspects of a low-intensity effusive basaltic eruption in great detail using multidisciplinary approaches. The Fagradalsfjall eruption followed a several-week long period of intense seismicity and deformation associated with formation of the feeding dike. The eruption terminated on September 18, 2021, after producing a lava field covering about 4.5 km2. The eruption progressed through several phases, each characterized by different emission sources, eruptive style, intensities, and associated hazards. The eruption may be representative of the formation of a shield volcano, a process that the scientific community has had limited chances to observe in real time.
We welcome submissions on sustained low-intensity basaltic eruptions including (but not limited to) the 2021 Fagradalsfjall eruption; their plumbling systems, eruptive products, and impacts. We particularly encourage comparative studies across different regions that may help us to better understand the volcanic processes that are active in the Fagradalsfjall eruption.
Topics may include, for example: physical volcanology of eruptive products and eruptive behavior; lava flow modeling; acoustic studies; petrology; geochemistry and interaction with groundwater; studies of volcanic gases; crustal deformation; seismology; volcano monitoring; social effects; health effects; hazard mitigation; tectonic implications; volcano-tectonic interactions; atmosphere-climate interactions, etc.

Many processes occurring on the Earth’s surface, such as landslides and debris flows, are natural hazards and cause risks for societies. Despite great research efforts, including approaches such as physical modelling, numerical simulation, and on-site monitoring, there are many open questions on these processes. Recently, with the development of environmental seismology, ground shaking measured by seismometers has become a promising tool to obtain quantitative information about surface processes that are difficult to observe otherwise. Therefore, it is possible to use seismic signals recorded by seismometers and geophones to provide new insights into Earth surface processes.
This session focuses on the formation, development, expansion, and extinction of surface processes, as well as their driving mechanism and inner interaction using seismic methods. Using observational, experimental or theoretical approaches, the topics of the presentations include but are not limited to:
(a) Natural seismic sources triggered by external phenomena, including those developing in the cryosphere (ice-quakes) and the hydrosphere (river, sediment transport, ocean).
(b) Natural seismic vibrations induced by geological disasters such as landslides, debris flows, flash floods, and many other hazards.
(c) Seismic wave propagation in the solid Earth due to processes in relation with the external environment, including hydro-meteorological, thermal evolution, and erosion processes.

Increasing effects of climate change, urbanization, and increased interconnectedness between ecological, physical, human, and technological systems pose major challenges to disaster risk management in a globalised world. Economic losses from natural hazards and climate change are still increasing, and the recent series of catastrophic events across the world together with the COVID-19 crisis has manifested the urgent need to shift from single-hazard-based approaches to new and innovative ways of assessing and managing risk based on a multi-hazard and systemic risk lens. This calls for novel scientific approaches and new types of data collections to integrate the study of multiple natural processes and human influences triggering hazards, including studies of ecological, physical, socioeconomic, political, and technical factors that shape exposure and vulnerability of humans, sectors and systems across borders and scales.
Tackling the above challenges, this session aims to gather the latest research, empirical studies, and observation data that are useful for understanding and assessing the interplay between multiple natural hazards and social vulnerability to: (i) identify persistent gaps, (ii) propose potential ways forward, and (iii) inform resilience building strategies in the context of global change.

The purpose of this session is to: (1) showcase the current state-of-the-art in global and continental scale natural hazard risk science, assessment, and application; (2) foster broader exchange of knowledge, datasets, methods, models, and good practice between scientists and practitioners working on different natural hazards and across disciplines globally; and (3) collaboratively identify future research avenues.
Reducing natural hazard risk is high on the global political agenda. For example, it is at the heart of the Sendai Framework for Disaster Risk Reduction and the Paris Agreement. In response, the last decade has seen an explosion in the number of scientific datasets, methods, and models for assessing risk at the global and continental scale. More and more, these datasets, methods and models are being applied together with stakeholders in the decision decision-making process.
We invite contributions related to all aspects of natural hazard risk assessment at the continental to global scale, including contributions focusing on single hazards, multiple hazards, or a combination or cascade of hazards. We also encourage contributions examining the use of scientific methods in practice, and the appropriate use of continental to global risk assessment data in efforts to reduce risks. Furthermore, we encourage contributions focusing on globally applicable methods, such as novel methods for using globally available datasets and models to force more local models or inform more local risk assessment.

Earthquake disaster mitigation involves different elements, ranging from analysis of hazards (e.g. physical description of ground shaking) to its impact on built and natural environment, from vulnerability and exposure to hazards to capacity building and resilience, from long-term preparedness to post-event response. The scientific base of this process involves various seismic hazard/risk models, developed at different time scales and by different methods, as well as the use of heterogeneous observations and multi-disciplinary information. Accordingly, we welcome contributions about different types of seismic hazards research and assessments, both methodological and practical, and their applications to disaster risk reduction in terms of physical and social vulnerability, capacity and resilience.
This session aims to tackle theoretical and implementation issues, as well as aspects of communication and science policy, which are all essential elements towards effective disasters mitigation, and include:
⇒ development of physical/statistical models for the different earthquake risk components (hazard, exposure, vulnerability), including novel methods for data collection and processing (e.g. statistical machine learning analysis)
⇒ earthquake hazard and risk estimation at different time and space scales, including their performance verification against observations (including unconventional seismological observations);
⇒ time-dependent seismic hazard and risk assessments (including contribution of aftershocks), and post-event information (early warning, alerts) for emergency management;
⇒ earthquake-induced cascading effects (e.g. landslides, tsunamis, etc) and multi-risk assessment (e.g. earthquake plus flooding).
The interdisciplinary session will provide an opportunity to share best practices and experience gained with different methods, providing opportunities to advance our understanding of disaster risk in "all its dimensions of vulnerability, capacity, exposure of persons and assets, hazard characteristics and the environment", while simultaneously highlighting existing gaps and future research directions.
Numerical modeling of earthquakes provides new approaches to apprehend the physics of earthquake rupture and the seismic cycle, seismic wave propagation, fault zone evolution and seismic hazard assessment.
Recent advances in numerical algorithms and increasing computational power enable unforeseen precision and multi-physics components in physics-based earthquake simulation but also pose challenges in terms of fully exploiting modern supercomputing infrastructure, realistic parameterization of simulation ingredients and the analysis of large synthetic datasets while advances in laboratory experiments link earthquake source processes to rock mechanics.
This session aims to bring together modelers and data analysts interested in the physics and computational aspects of earthquake phenomena and earthquake engineering. We welcome studies focusing on all aspects of seismic hazard assessment and the physics of earthquakes - from slow slip events, fault mechanics and rupture dynamics, to wave propagation and ground motion analysis, to the seismic cycle and inter seismic deformation - and studies which further the state-of-the art in the related computational and numerical aspects.
New models based on seismicity patterns, considering their physical meaning and their statistical significance, shed light on the preparation process of large earthquakes and on the evolution in time and space of clustered seismicity.
Opportunities for improved model testing are being opened by the increasing amount of earthquake data available on local to global scales, together with accurate assessments of the catalogues’ reliability in terms of location precision, magnitude of completeness and coherence in magnitude determination.
Moreover, it is possible to reliably integrate the models with additional information, like geodetic deformation, active fault data, source parameters of previously recorded seismicity, fluid contents, tomographic information, or laboratory and numerical experiments of rock fracture and friction. Such integration allows a detailed description of the system and hopefully an improved forecasting of the future distribution of seismicity in space, time and magnitude.
In this session, we invite researchers to submit their latest results and insights on the physical and statistical models and machine learning approaches for the space, time and magnitude evolution of earthquake sequences. Particular emphasis will be placed on:
• physical and statistical models of earthquake occurrence;
• analysis of earthquake clustering;
• spatial, temporal and magnitude properties of earthquake statistics;
• quantitative testing of earthquake occurrence models;
• reliability of earthquake catalogues;
• time-dependent hazard assessment;
• methods for earthquake forecasting;
• data analyses and requirements for model testing;
• pattern recognition in seismology;
• machine learning applied to seismic data; and
• methods for quantifying uncertainty in pattern recognition and machine learning.

QuakeMigrate is a new, open-source software package for automatic earthquake detection and location (https://github.com/QuakeMigrate/QuakeMigrate). Our software provides a means for seismologists to extract highly complete catalogues of microseismicity from continuous seismic data, whether their network is installed at a volcano, plate-boundary fault zone, on an ice shelf, or even on another planet. Rather than traditional pick-based techniques, it uses a migration-based approach to combine the recordings from stations across a seismic network, promising increased robustness to noise, more accurate hypocentre locations, and improved detection capability. Cloud-hosted Jupyter Notebooks and tutorials (https://mybinder.org/v2/gh/QuakeMigrate/QuakeMigrate/master) provide an overview of the philosophy and capabilities of our algorithm, and in this session we intend to provide a more hands-on introduction, with a focus on providing a general understanding of the considerations when applying a waveform-based algorithm to detect and locate seismicity.
QuakeMigrate has been constructed with a modular architecture, to make it flexible to use in different settings. We will demonstrate its use in detecting and locating basal icequakes at the Rutford Ice Stream, Antarctica, volcano-tectonic seismicity during the 2014 Bárðarbunga-Holuhraun and 2021 Reykjanes/Fagradalsfjall dike intrusions, and aftershocks from a M5 tectonic earthquake in northern Borneo, which was recorded on a sparse regional seismic network. In each case we will discuss the reasoning behind parameter selections, and the key factors in maximising detection sensitivity while minimising computational cost. We will end the session by exploring sample datasets provided by attendees, with interactive involvement as we tune parameters and use the comprehensive array of automatically generated plots to take a preliminary look at unseen data.

How do seismologists detect earthquakes? How do we locate them? Is seismology only about earthquakes? Seismology has been integrated into a wide variety of geo-disciplines to complement many fields such as tectonics, geology, geodynamics, volcanology, hydrology, glaciology and planetology. This 90-minute course is part of the Solid Earth 101 short course series together with ‘Geodynamics 101’ and ‘Geology 101’ to better illustrate the link between these fields.
In ‘Seismology 101’, we will introduce the basic concepts and methods in seismology. In previous years, this course was given as “Seismology for non-seismologists”, and it is still aimed at those not familiar with seismology -- particularly early-career scientists. An overview will be given on various methods and processing techniques applicable to investigate surface processes, near-surface geological structures, and the Earth’s interior. The course will highlight the role that advanced seismological techniques can play in the co-interpretation of results from other fields. The topics will include:
- the basics of seismology, including the detection and location of earthquakes
- understanding and interpreting those enigmatic “beachballs”
- an introduction to free seismo-live.org tutorials and other useful tools
- how seismic methods are used to learn about the Earth, such as imaging the Earth’s interior (on all scales), deciphering tectonics, monitoring volcanoes, landslides and glaciers, etc...
We likely won’t turn you in the next Charles Richter in 90 minutes but would like to make you aware of how seismology can help you with your research. The intention is to discuss each topic in a non-technical manner, emphasizing their strengths and potential shortcomings. This course will help non-seismologists better understand seismic results and facilitate more enriched discussion between different scientific disciplines. The short course is organised by early-career scientist seismologists and geoscientists who will present examples from their own research experience and high-impact reference studies for illustration. Questions from the audience on the topics covered will be highly encouraged.

Scientific drilling through the International Ocean Discovery Program (IODP) and the International Continental Scientific Drilling Program (ICDP) continues to provide unique opportunities to investigate the workings of the interior of our planet, Earth’s cycles, natural hazards and the distribution of subsurface microbial life. The past and current scientific drilling programs have brought major advances in many multidisciplinary fields of socio-economic relevance, such as climate and ecosystem evolution, palaeoceanography, the deep biosphere, deep crustal and tectonic processes, geodynamics and geohazards. This session invites contributions that present and/or review recent scientific results from deep Earth sampling and monitoring through ocean and continental drilling projects. Furthermore, we encourage contributions that outline perspectives and visions for future drilling projects, in particular projects using a multi-platform approach.

What role did climate dynamics play in human evolution, the dispersal of different Homo species within and beyond the African continent, and key cultural innovations? Were dry spells, stable humid conditions, or rapid climate fluctuations the main driver of human evolution and migration? In order to evaluate the impact that different timescales and magnitudes of climatic shifts might have had on the living conditions of prehistoric humans, we need reliable and continuous reconstructions of paleoenvironmental conditions and fluctuations from the vicinity of paleoanthropological and archaeological sites. The search for the environmental context of human evolution and mobility crucially depends on the interpretation of paleoclimate archives from outcrop geology, lacustrine and marine sediments. Linking archeological data to paleoenvironmental reconstructions and models becomes increasingly important.
As a contribution towards a better understanding of these human-climate interactions the conveners encourage submission of abstracts on their project’s research on (geo)archaeology, paleoecology, paleoclimate, stratigraphy, and paleoenvironmental reconstructions. We especially welcome contributions offering new methods for dealing with difficult archive conditions and dating challenges. We hope this session will appeal to a broad audience by highlighting the latest research on paleoenvironmental reconstructions in the vicinity of key sites of human evolution, showcasing a wide variety of analytical methods, and encouraging collaboration between different research groups. Conceptual models, modelling results and model-data comparisons are warmly welcomed, as collaborative and interdisciplinary research.

The Quaternary Period (last 2.6 million years) is characterized by frequent and abrupt climate swings that were accompanied by rapid environmental change. Studying these changes requires accurate and precise dating methods that can be effectively applied to environmental archives. A range of different methods or a combination of various dating techniques can be used, depending on the archive, time range, and research question. Varve counting and dendrochronology allow for the construction of high-resolution chronologies, whereas radiometric methods (radiocarbon, cosmogenic in-situ, U-Th) and luminescence dating provide independent anchors for chronologies that span over longer timescales. We particularly welcome contributions that aim to (1) reduce, quantify and express dating uncertainties in any dating method, including high-resolution radiocarbon approaches; (2) use established geochronological methods to answer new questions; (3) use new methods to address longstanding issues, or; (4) combine different chronometric techniques for improved results, including the analysis of chronological datasets with novel methods, e.g. Bayesian age-depth modeling. Applications may aim to understand long-term landscape evolution, quantify rates of geomorphological processes, or provide chronologies for records of climate change.

Continental rifting is a complex process spanning from the inception of extension to continental rupture or the formation of a failed rift. This session aims at combining new data, concepts and techniques elucidating the structure and dynamics of rifts and rifted margins. We invite submissions highlighting the time-dependent evolution of processes such as: initiation and growth of faults and ductile shear zones, tectonic and sedimentary history, magma migration, storage and volcanism, lithospheric necking and rift strength loss, influence of the pre-rift lithospheric structure, rift kinematics and plate motion, mantle flow and dynamic topography, as well as break-up and the transition to sea-floor spreading. We encourage contributions using multi-disciplinary and innovative methods from field geology, geochronology, geochemistry, petrology, seismology, geodesy, marine geophysics, plate reconstruction, or numerical or analogue modelling. Special emphasis will be given to presentations that provide an integrated picture by combining results from active rifts, passive margins, failed rift arms or by bridging the temporal and spatial scales associated with rifting.

Birth, evolution, and demise of sedimentary basins result from the interplay of several factors such as the geodynamic/tectonic regime, stress field, thickness and thermal state of the lithosphere, rheological properties of both basement and sedimentary fill, and faults architecture. Integrated studies, including the analyses of structural setting and thermal maturity of stratigraphic successions, have shown to be successful in unravelling the tectonic evolution of active basins as well as fossil ones that have been later incorporated into orogenic belts.
In this session, we welcome contributions from researchers in all fields of geosciences, applying different analytical methods to the study of worldwide active and fossil sedimentary basins. These methods can include, but are not limited to, structural analyses (both on outcropping and subsurface rocks), thermal maturity assessments, fault dating, geochronological and thermochronological dating, and isotopic analyses on carbonates. Multidisciplinary approaches are greatly welcomed. The aim is to foster discussion on which are the best procedures to better understand the geological processes that drive the tectonic and thermal history of sedimentary basins and their surrounding regions.

Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

It is now well known that the coupling between tectonics, climate and surface processes governs the dynamics of mountain belts and basin. However, the amplitude of these couplings and their exact impact on mountain building are less understood. First order quantitative constraints on this coupling are therefore needed. They can be provided by geomorphic and sedimentary records including longitudinal river profiles, fluvial terraces, downstream fining trends, growth strata, sediment provenance, sequence stratigraphy, and changing depositional environments. Moreover, the increasing integration of geochronological methods for quantifying erosion rates and source-to-sink sediment transfer with landscape evolution, stratigraphic, climatic, and tectonic models allows to advance our understanding of the interactions between surface processes, climate and tectonic deformation.
We invite contributions that use geomorphic and/or sedimentary records to understand tectonic deformation, climate histories, and surface processes, and welcome studies that address their interactions and couplings at a range of spatial and temporal scales. In particular, we encourage coupled catchment-basin studies that take advantage of numerical/physical modelling, geochemical tools for quantifying rates of surface processes (cosmogenic nuclides, low-temperature thermochronology, luminescence dating) and high resolution digital topographic and subsurface data. We invite contributions that address the role of surface processes in modulating rates of deformation and tectonic style, or of tectonics modulating the response of landscapes to climate change.

Carbonate (bio)minerals have played an essential role in the history of life on Earth and form one of the most important archives for past climate and environmental change. Geochemical investigations are crucial for understanding the evolution of microbial habitats and the paleobiology of carbonate biomineralizers and for assessing changes in the atmosphere-hydrosphere systems through time. With this session, we encourage contributions from sedimentology, geochemistry and biology that utilize carbonate (bio)minerals (e.g., microbialites, stromatolites, mollusk shells and foraminifera) with the aim to reconstruct paleo-environments, seasonality, seawater chemistry and paleobiology in a wide range of modern to deep time settings, including critical intervals of environmental and climate change. This includes sedimentological and biological reconstructions of palaeo-environments, theoretical or experimental studies of trace element partitioning and isotope fractionation in carbonate (bio)minerals, and studies targeting original skeletal carbonate preservation and diagenetic alteration.

The pacing of the global climate system by orbital variations is clearly demonstrated in the timing of e.g. glacial-interglacial cycles. The mechanisms that translate this forcing into geoarchives and climate changes continue to be debated. We invite submissions that explore the climate system response to orbital forcing, and that test the stability of these relationships under different climate regimes or across evolving climate states (e.g. mid Pleistocene transition, Pliocene-Pleistocene transition, Miocene vs Pliocene, and also older climate transitions). Submissions exploring proxy data and/or modelling work are welcomed, as this session aims to bring together proxy-based, theoretical and/or modelling studies focused on global and regional climate responses to astronomical forcing at different time scales in the Phanerozoic.

The geological record provides insight into how climate processes operate and evolve in response to different than modern boundary conditions and forcings. Understanding deep-time climate evolution is paramount to progressing on understanding fundamental questions of Earth System feedbacks and sensitivity to perturbations, such as the behaviour of the climate system under elevated atmospheric CO2 levels—relative to the Quaternary—, or the existence of climatic tipping points and thresholds. In recent years, geochemical techniques and Earth System Models complexity have been greatly improved and several international projects on deep-time climates (DeepMIP, MioMIP, PlioMIP) have been initiated, helping to bridge the gap between palaeoclimate modelling and data community. This session invites work on deep-time climate simulations and proxy-based reconstructions from the Cambrian to the Pliocene. We especially encourage submissions featuring palaeoenvironmental reconstructions, palaeoclimate modelling, and the integration of proxies and models of any complexity.
The rates and dates of processes occurring at tectonic-plate scale can be quantified using evidence derived from actively deforming settings, including geomorphic markers (e.g., topography and rivers, fluvial deposits, marine terraces) and sedimentary archives (e.g., syntectonic sedimentation, stratigraphic evidence).
When used as key natural laboratories at adequate time spans, such evidence provides essential clues to understand large-scale tectonics. These focused studies may contribute to unravel the motion, deformation, and evolution of tectonic plates, as well as changes in their potential geodynamics and boundary conditions.
We invite contributions focusing on understanding the dynamics and evolution of deforming plate interiors and active plate boundaries through interdisciplinary, geomorphic, or sedimentary data-based approaches. We welcome all types of studies that aim to quantify the rates of active plate deformation and the dates of tectonic events, regardless of their spatio-temporal scale or methodology.

Geomorphic and geologic observations at the Earth's surface reflect the combined effects of mantle, lithospheric, and surface processes. Hence surface observations provide important constraints on mantle convection patterns and plume-plate interactions both at plate boundaries and in intraplate settings through space and time. These observations complement geophysical data and are important constraints for theoretical models and numerical simulations. For instance, at plate boundaries, surface observations can provide key constraints on the rheology and kinematics of lithospheric and mantle processes. In both plate boundary and intraplate settings, mantle plumes can trigger continental rifting and break-up, subduction initiation, orogeny, microcontinent formation, and/or the development of dynamic topography. However, using surface observations to constrain mantle processes is complicated by (1) our as yet incomplete understanding of how mantle dynamics manifest at the surface, and (2) spatio-temporal variations in tectonic processes, climate, isostatic adjustment, lithology, biota, and human alteration of landscapes. In this session, we aim to bring together researchers interested in mantle-surface and plume-plate interactions. We welcome studies that cover a range of techniques from data-driven approaches to numerical modelling or laboratory experiments.
We hope this session will provide opportunities for presenters from a range of disciplines, demographics, and stages of their scientific career to engage in this exciting and emerging problem in Earth Science.
Volcanoes are inherently complex and dynamic geological system, acting as the source of diverse sediment types and as a control on varied sediment transport processes within surrounding environments, both during and after their life. This can manifest as an accumulation of thick primary volcaniclastic sequences from pyroclastic (e.g. pyroclastic density currents, tephra falls), laharic and flank instability processes, secondary volcaniclastic sequences from the reworking/redeposition (or both) of primary deposits and their interaction with non-volcanic sedimentary processes, or deposits from the weathering of lava flows. The diversity of processes that may be involved in the generation of volcaniclastic sequences makes often difficult to describe and interpret them. As the comprehension of the generation, transportation and accumulation mechanisms of volcaniclastic sequences is of extreme importance for natural hazard and economic perspectives, to reduce uncertainties and move forward in the identification of volcano-sedimentary processes and potential effects, modern and ancient volcaniclastic sequences must be studied and interpreted hand in hand. Thus, the proposed session aims to bring together studies that explore the volcaniclastic record of modern and ancient environments. Contributions are welcomed in areas including, but not limited to, the identification of volcanic features in ancient sedimentary records, multidisciplinary (e.g., stratigraphic, petrographic, geophysical) approaches to the study of modern subaerial and submarine volcaniclastic sequences as analogue sites, and examples of the modification of sedimentary systems across syn- and inter-eruptive periods.

During the past decades numerous sediment records have become available from lakes and paleolakes through shallow and (ICDP) deep drilling. These records have proven to be valuable archives of past climate and environmental change, human activities as well as tectonic and volcanic activity. We invite contributions emphasizing quantitative and spatial assessments of rates of change, causes and consequences of long- and short-term climate variability, impact, magnitude, and frequency of tectonic and volcanic activity as deduced from sedimentological, geochemical, biological, and chronological tools.

Carbonate sediments have formed in a wide range of marine and non-marine settings through the complex interplay of biological, chemical and physical processes. Precisely-constrained high-resolution stratigraphic records are important for determining past global change and understanding the complex interactions between climatic processes, oceanographic and environmental changes, the biosphere, stratigraphic architecture and subsequent diagenesis. The complementary study of Recent carbonate depositional systems is crucial to the interpretation of these systems. This session invites contributions from general and interdisciplinary topics within the diverse fields of Carbonate Sedimentology, Stratigraphy and Diagenesis, the session will explore a broad range of geochemical, biological and stratigraphic proxies and their applications to understanding Earth history.

Speleothems and other continental carbonates (e.g. travertines, pedogenic, lacustrine, subglacial and cryogenic carbonates) are important terrestrial archives, which can provide precisely dated, high-resolution records of past environmental and climate changes. The field of carbonate-based paleoclimatology has seen (1) continuously improving analytical capacity, supporting the compilation of detailed records of climate variability integrating established as well as novel and innovative techniques. (2) Long-term environmental monitoring campaigns facilitating the interpretation of high-resolution proxy time series from carbonate archives. (3) The continuous development of proxy-system models that can help understand the measured proxies, by describing processes such as water infiltration, carbonate dissolution, precipitation and diagenesis. (4) The development of proxy databases such as SISAL (Speleothem Isotope Synthesis and AnaLysis) which enable regional-to-global scale analysis of the relationship between the proxy and the environmental parameter using a variety of large data analysis and data-model comparison techniques.
Applied together, advancements in these cornerstones pave the way towards developing highly reliable and quantitative terrestrial climate reconstructions. This session aims to bring together integrated and interdisciplinary studies in order to better understand the precipitation environment of continental carbonates and the incorporation of climate-sensitive proxies at various time scales. We especially invite contributions that show progress in one of the four outlined domains, and welcome speleothem and carbonate-based modern and paleoenvironmental studies, including new records of past climatic changes. In addition, research contributing to current international co-ordinated activities, such as the PAGES working group on Speleothem Isotopes Synthesis and AnaLysis (SISAL) and others are welcome.

Minerals are formed in great diversity under Earth surface conditions, as skeletons, microbialites, speleothems, or authigenic cements, and they preserve a wealth of geochemical, biological, mineralogical, and isotopic information, providing valuable archives of past environmental conditions. Interpreting these archives requires fundamental understanding of mineral formation processes, but also insights from the geological record.
In this session we welcome oral and poster presentations from a wide range of research of topics, including process-oriented studies in modern systems, the ancient rock record, experiments, computer simulations, and high-resolution microscopy and spectroscopy techniques. We intend to reach a wide community of researchers sharing the common goal of improving our understanding of the fundamental processes underlying mineral formation, which is essential to read our Earth’s geological archive.

Tsunamis and storm surges pose significant hazards to coastal communities around the world. Geological investigations, including both field studies and modelling approaches, significantly enhance our understanding of these events. Past extreme wave events may be reconstructed based on sedimentary and geomorphological evidence from low and high energy environments, from low and high latitude regions and from coastal and offshore areas. The development of novel approaches to identifying, characterising and dating evidence for these events supplements a range of established methods. Nevertheless, the differentiation between evidence for tsunamis and storms still remains a significant question for the community. Numerical and experimental modelling studies complement and enhance field observations and are crucial to improving deterministic and probabilistic approaches to hazard assessment. This session welcomes contributions on all aspects of paleo-tsunami and paleo-storm surge research, including studies that use established methods or recent interdisciplinary advances to reconstruct records of past events, or forecast the probability of future events.
The action of a fluid moving over a mobile surface often generates bedforms which in turn influence the flow and how particles are transported. On Earth, bedforms are found in many environments: deserts, rivers, estuaries, continental shelves, deep seas, volcanic regions and glacial environments. Bedforms have also been observed in extra-terrestrial environments, such as on Mars and Venus.
Understanding the links between flow, particle transport, and bedform morphodynamics and stratigraphy is of interest for a wide range of applied and fundamental research. For example, this knowledge is used to manage contemporary environments, such as rivers and coastal seas. Recently, the societal relevance of bedform research has been highlighted, as bedforms are shown to interact with offshore structures. Furthermore, bedform morphology and sedimentology can provide insights into fluid movement across modern and ancient, otherwise unknown, landscapes.
This session aims to highlight many aspects of the complex interaction between flow, sediment transport, stratigraphy and bedforms in terrestrial and planetary environments. The session welcomes contributions from theoretical, field, laboratory and numerical approaches related to bedforms found in aeolian, shallow and deep waters, glacial and planetary environments. The session intends to advance our knowledge of how to decipher information contained in terrestrial and extra-terrestrial bedforms and help foster fruitful discussions on understanding bedform morphodynamics and stratigraphy.

The ocean floor hosts a tremendous variety of forms that reflect the action of a range of tectonic, sedimentary, oceanographic and biological processes at multiple spatio-temporal scales. Many such processes are hazards to coastal populations and offshore installations, and their understanding constitutes a key objective of national and international research programmes and IODP expeditions. High quality bathymetry, especially when combined with sub-seafloor and/or seabed measurements, provides an exciting opportunity to integrate the approaches of geomorphology and geophysics, and to extend quantitative geomorphology offshore. 3D seismic reflection data has also given birth to the discipline of seismic geomorphology, which has provided a 4D perspective to continental margin evolution.
This interdisciplinary session aims to examine the causes and consequences of geomorphic processes shaping underwater landscapes, including submarine erosion and depositional processes, submarine landslides and canyons, sediment transfer and deformation, volcanic activity, fluid migration and escape, faulting and folding, and other processes acting at the seafloor. The general goal of the session is to bring together researchers who characterise the shape of past and present seafloor features, seek to understand the sub-surface and surface processes at work and their impacts, or use bathymetry and/or 3D seismic data as a model input. Contributions to this session can include work from any depth or physiographic region, e.g. oceanic plateaus, abyssal hills, mid-ocean ridges, accretionary wedges, and continental margins (from continental shelves to abyss plains). Datasets of any scale, from satellite-predicted depth to ultra high-resolution swath bathymetry, sub-surface imaging and sampling, are anticipated.

Arid to sub-humid regions are home for >40% of the world’s population, and many prehistoric and historic cultures developed in these regions. Due to the high sensitivity of drylands to small-scale environmental changes and anthropogenic activities, ongoing geomorphological processes but also the Late Quaternary geomorphological and palaeoenvironmental evolution as recorded in sediment archives are becoming increasingly relevant for geological, geomorphological, palaeoenvironmental, palaeoclimatic and geoarchaeological research. Dryland research is constantly boosted by technological methodological advances, and especially by emerging linkages with other climatic and geomorphic systems that allow using dryland areas as indicator-regions of global environmental changes.
This session aims to pool contributions that deal with current and former geomorphological processes and environmental changes, as well as with all types of sediment archives in dryland areas (dunes, loess, slope deposits, fluvial sediments, alluvial fans, lake and playa sediments, desert pavements, soils, palaeosols etc.) at different spatial and temporal scales. Besides case studies from individual regions and archives and review studies, methodical and conceptual contributions are especially welcome in this session, e.g. dealing with the special role of aeolian, fluvial, gravitational and biological processes in dryland environments, sediment preservation, methods to obtain chronological frameworks and process rates, emerging geo-technologies and the role of such processes for current and former societies.

The geological records of glaciations provide information on the Earth’s past climate and on the efficiency of glaciers in modifying landscapes. Traces of glacial activity are manifested in characteristic depositional and erosional landforms. The focus of this session is to stimulate discussions about the challenges and advances in understanding glaciations and glacial records with a special emphasis on the Quaternary period: How do landscapes and erosion rates evolve under the repeated impact of glaciations? What is the impact of early vs. late glaciations during an ice age? What are the (chrono-)stratigraphic challenges for better constraining glacial periods, especially during earlier periods of the Quaternary? How do climatic conditions affect glaciations and vice versa? How do Quaternary sediments compare to deposits of ice ages earlier in Earth’s history?
Repeated glaciation of an area tends to overprint older landforms and creates fragmented sedimentary successions. For the last glacial cycle, for instance, timing, extent, and driving mechanisms are increasingly well understood, whereas landscape evolution and trends in topographic preconditioning remain poorly constrained for previous glacial cycles. This complexity tends to accentuate when pre-Quaternary glaciations are considered.
We are therefore particularly interested in contributions that demonstrate how some of the limitations imposed by the geological records’ fragmentation can be overcome. For instance, by the following approaches:
1. Uncovering and characterizing glacial deposits, for example preserved in subglacially formed basins (overdeepened basins, tunnel valleys, and fjords), extend the accessible sedimentary record.
2. Modern and ancient analogues help to understand erosion and deposition mechanisms in glacial environments.
3. Relative and absolute chronostratigraphy allows the development of a temporal framework of landscape evolution and environmental conditions.
Contributions may include investigations based on field observations, scientific drilling, geophysical measurements, and/or modelling of present-day, Quaternary, and pre-Quaternary glacial settings. Possible topics cover: (a) glacial and interglacial stratigraphic successions, (b) subglacial erosion and deposition, (c) glaciation chronology, and (d) landscape evolution.

Present-day glacial and periglacial processes in cold regions, i.e. arctic and alpine environments, provide modern analogues to processes and climatic changes that took place during the Pleistocene, including gradual retreat or collapse of ice sheets and mountain glaciers, and thawing and shrinking of low-land permafrost. Current geomorphological and glaciological changes in mid-latitude mountain ranges could also serve as a proxy for future changes in high-latitude regions within a context of climate change. Examples are speed-up or disintegration of creeping permafrost features or the relictification of rock glaciers.
For our session we invite contributions that either:
1. investigate present-day glacial and/or periglacial landforms, sediments and processes to describe the current state, to reconstruct past environmental conditions and to predict future scenarios in cold regions; or
2. have a Quaternary focus and aim at enhancing our understanding of past glacial, periglacial and paraglacial processes, also through the application of dating techniques.
Case studies that use a multi-disciplinary approach (e.g. field, laboratory and modelling techniques) and/or that highlight the interaction between the glacial, periglacial and paraglacial cryospheric components in cold regions are particularly welcome.

The interactions between aerosols, climate, and weather are among the large uncertainties of current atmospheric research. Mineral dust is an important natural source of aerosol with significant implications on radiation, cloud microphysics, atmospheric chemistry and the carbon cycle via the fertilization of marine and terrestrial ecosystems. In addition, properties of dust deposited in sediments and ice cores are important (paleo-)climate indicators.
This interdivisional session --building bridges between the EGU divisions CL, AS, SSP, BG and GM-- had its first edition in 2004 and it is open to contributions dealing with:
(1) measurements of all aspects of the dust cycle (emission, transport, deposition, size distribution, particle characteristics) with in situ and remote sensing techniques,
(2) numerical simulations of dust on global, regional, and local scales,
(3) meteorological conditions for dust storms, dust transport and deposition,
(4) interactions of dust with clouds and radiation,
(5) influence of dust on atmospheric chemistry,
(6) fertilization of ecosystems through dust deposition,
(7) any study using dust as a (paleo-)climate indicator, including sediment archives in loess, ice cores, lake sediments, ocean sediments and dunes.
We especially encourage the submission of papers that integrate different disciplines and/or address the modelling of past, present and future climates.

Aeolian processes are active on various planetary surfaces throughout the Solar System and yield similar landforms across a wide range of spatial scales despite differences in atmospheric and surface properties. They are typically associated with the movement of sediments driven by an atmospheric flow but can also be controlled by other modes of matter transport such as ice sublimation. The combination of terrestrial and extra-terrestrial experiments and observations provides the opportunities as well as challenges for improving our fundamental theories and numerical models for better understanding of these aeolian environments. Innovations in instrumentation and experimental techniques continue to yield novel insights on Earth, while space missions and remote probes constantly deliver new and surprising evidence from aeolian environments on other planetary bodies. This session welcomes research on all aspects of aeolian processes and landforms, contemporary and ancient, on planetary surfaces across the Solar System.

Integrating sedimentology, geomorphology, and structural geology to better understand the weathering, erosion, transfer, and storage of sediment from source to sink is an inherently interdisciplinary field. Disentangling signals and their landscape response has a breadth of implications within managing present-day resources, reconstructing paleoenvironments, and fostering understanding of the evolution of our planet. More recently, anthropogenic actions add further complexity within signal interpretations and alter landscape dynamics.
Within the source to sink approach, sediments are generally produced in mountainous areas through weathering and transported via sediment routing systems (SRS) to a zone of final deposition. Terrestrially derived sediments in sedimentary archives are regularly used to reconstruct past climatic or tectonic conditions. Environmental reconstructions are based on the assumption that perturbations in climatic or tectonic conditions generate signals within the transported sediment. However, experimental and numerical studies have shown that not all signals are faithfully transmitted, but can be modified, buffered or even lost during transport along the SRS. Therefore, quantifying the spatial and temporal constraints of signal transfer and storage (eg: transience vs steady-state conditions and basin response times) are just as critical to sedimentary interpretation as the understanding the magnitude and duration of the source signal (eg: periodicity of the environmental forcing).
We would like to encourage discussion and build an international community between researchers within academic circles and industry who are applying a comprehensive source to sink systems approach. We are especially interested in sedimentary proxy generation during environmental changes (eg: surface and regolith biogeochemical weathering or physical grain size signals), transport (eg: modern autogenic dynamics, palaeohydraulics, and signal tracing), and archiving (eg: reservoir prediction) controls on the SRS. Contributions across diverse approaches (eg. modeling to field-based studies), environments (continental to marine), and time scales (human to geologic) are encouraged.
The never-ending growth of the ground penetrating radar applications reserves continuously small and less small discoveries, and deserves a space for discussion and reciprocal listening also at the EGU conference.
The pandemic has meaningfully hindered many activities but to our knowledge not too much the interest in the GPR instrumentation and technique at an applicative level, even if exchanges of experiences at international conferences have been of course necessarily reduced. So, we hope that this session can meet the interest of many researchers, professionals, PhD students as well skilled GPR users as geologists, engineers, geophysicists and possibly archaeologists and architects.
Contributions are welcome with regard to all the aspects of the GPR technique, ranging from the hardware of the systems to the data processing and any theoretical aspect, including innovative applications or procedures as well as results of particular relevance, possibly achieved within an integrated measurement campaign including also different data.
Hope to see you in Vienna.
This 105-minute short course aims to introduce non-geologists to structural and petrological geological principles, which are used by geologists to understand system earth.
The data available to geologists is often minimal, incomplete and representative for only part of the geological history. Besides learning field techniques to acquire and measure data, geologists need to develop a logical way of thinking to close gaps in the data to understand the system. There is a difference in the reality observed from field observation and the final geological model that tells the story.
In this course we briefly introduce the following subjects:
1) Grounding rocks: Introduction to the principles of geology.
2) Collecting rocks: The how, what, and pitfalls of field data acquisition.
3) Failing rocks: From structural field data to (paleo-)stress analysis.
4) Dating rocks: Absolute and relative dating of rocks using petrology and geochronology methods.
5) Shaping rocks: The morphology of landscapes as tectonic constraints
6) Crossing rocks over: How geology benefits from seismology, geodynamic and geodesy research, and vice-versa.
7) Q&A!
Our aim is not to make you the next specialist in geology, but we would rather try and make you aware of the challenges a geologist faces when they go out into the field. Additionally, the quality of data and the methods used nowadays are addressed to give other earth scientists a feel for the capabilities and limits of geological research. This course is given by Early Career Scientist geologists and geoscientists and forms a quartet with the short courses on ‘Geodynamics 101 (A&B)’, ‘Seismology 101’, and ‘Geodesy 101’. For this reason, we will also explain what kind of information we expect from the fields of seismology, geodynamics and geodesy, and we hope to receive some feedback in what kind of information you could use from our side.

Within this course, the attendees are taught how to identify possible cyclicities in paleoclimate data (e.g., sediments, speleothems) or any other geological record. We will start from the basics of which data can be analysed, go over power spectra, and discuss the application of filters and Wavelet Analysis. We will discuss the advantages and disadvantages of different methods, and give some examples from Earth Sciences to highlight common pitfalls. The aim of this course is to give a brief overview of the most common techniques and give participants the insight to prepare and analyse their data themselves. A variety of computational platforms are available for time-series analysis. In this course, we will introduce different tools and techniques by making use of the programming language R.

Age models are applied in paleoclimatological, paleogeographic and geomorphologic studies to understand the timing of climatic and environmental change. Multiple independent geochronological dating methods are available to generate robust age models. For example, different kinds of radio isotopic dating, magneto-, bio-, cyclostratigraphy and sedimentological relationships along stratigraphic successions or in different landscape contexts. The integration of these different kinds of geochronological information often poses challenges.
Age-depth or chronological landscape models are the ultimate result of the integration of different geochronological techniques and range from linear interpolation to more complex Bayesian techniques. Invited speakers will share their experience in several modelling concepts and their application in a range of Quaternary paleoenvironmental and geomorphologic records. The Short Course will provide an overview of age models and the problems one encounters in climate science and geomorphology. Case studies and practical examples are given to present solutions for these challenges. It will prepare the participants from CL, GM and other divisions for independent application of suitable age-depth models to their climate or geomorphologic data.

MTEX (https://mtex-toolbox.github.io/) has become a standard tool for the quantification of crystallographic textures and microstructural-derived physical properties in geological materials. From the quantification of crystallographic preferred orientations (CPOs), intracrystalline deformation, grain sizes and shapes in geological materials, to determination of CPO-derived physical properties (e.g., elastic, piezoelectric), all is possible with MTEX.
In the first part of the short course, we will introduce basic concepts on how MTEX works. In the second part, we will run demonstrations of some application in geological materials.
The following topics will be covered:
1) Importing EBSD data, pre-processing;
2) Checking orientations, ODF quantification, plot of pole figures;
3) Grain segmentation, calculation of grain sizes and shapes;
4) Intracrystalline deformation analysis, subgrains, new grains;
5) Tensors and CPO-derived seismic properties
Demonstrations will be made using the MTEX toolbax in Matlab. Note, however, that familiarity with the toolbox is not required. - This is a short course, not a workshop.

Meet editors of internationally renowned journals in geo- and biogeoscience and gain exclusive insights into the publishing process. After a short introduction into some basics, we will start exploring various facets of academic publishing with short talks given by the editors on
- What are the duties and roles of editors, authors and reviewers?
- How to choose a suitable journal for your manuscript and what is important for early career authors?
- How can early career scientists get involved in successful peer-reviewing?
- What is important for appropriate peer-reviewing?
- What are ethical aspects and responsibilities of publishing?
Together with the audience and the editors, we will have an open discussion of the key steps and factors shaping the publication process of a manuscript. This short course aims to provide early career scientists across several EGU divisions (e.g. AS, BG, CL, GM, NH, SSP and SSS) the opportunity of using first hand answers of experienced editors of international journals to successfully publish their manuscripts and get aware of the potentials and pitfalls in academic publishing.

Publishing your research in a peer reviewed journal is essential for a career in research. All EGU-affiliated journals are fully open access which is great, but the unique open discussion and transparent peer review process can be daunting for first time submitters and early career scientists. This short course will cover all you need to know about the publication process from start to end for EGU journals, and give you a chance to ask the editors some questions. This includes: what the editor looks for in your submitted paper, how to deal with corrections or rejections, and how best to communicate with your reviewers and editors for a smooth transition from submission to publication. Ample time will be reserved for open discussion for the audience to ask questions to the editors, and for the editors to suggest ‘top tips’ for successful publication. This course is aimed at early-career researchers who are about to step into the publication process, and those who are yet to publish in EGU journals. Similarly, this course will be of interest to those looking to get involved in the peer-review process through reviewing and editing. This short course is part of the “Meet the EGU Journal Editors” webinar series that was held prior to the EGU General Assembly 2022.

We are excited to welcome our panelists for this session, who will be representing their respective journals:
The work of scientists does not end with publishing their results in peer-reviewed journals and presenting them at specialized conferences. In fact, one could argue that the work of a scientist only starts at this point: outreach. What does outreach mean? Very simply, it means to engage with the wider (non-scientific) public about science. There are many ways to do outreach, including blogging and vlogging, using social media, writing for a science dissemination journal, participating as a speaker at local science festivals, organising open days in the laboratory, and so on.
With this short course, we aim to give practical examples of different outreach activities, how to start an outreach project and tips and suggestions from personal and peers’ experiences. Specific attention will be paid to science communication issues, including the proper ‘translation’ of the jargon of science into language the public understands, the selection of the content being conveyed, and the best format in which it is presented according to the different targets (policymakers, the general public, school-age children, etc.).
In the last part of the course, you will work singularly to come up with an outreach idea based on your research. You may use it on your next proposal; you never know!

Rationale
The proper and deep education on ethical issues in geosciences has been evolving in recent times, although not as quickly and deeply as necessary. Many of the professionals dedicated to Earth Sciences have been not in touch with such new concepts and tendencies. Geoethics is the research and reflection on the values that underpin appropriate behaviors and practices, wherever human activities interact with the Earth system. It provides a framework to define ethical professional behaviors in Earth sciences and engineering and to determine how these should be put into practice for the benefit of environment and society. The Short Course is directed towards introducing and training Earth scientists in those new concepts and ideas as well as exposing the perspectives of this field. Social-ecological Systems and the anthropic impact on land, ocean, and atmosphere are at the cores issues to be discussed under the umbrella of geoethics, as a tool to cope with Climate Changes and other earth-society related challenges.
Completing this course, participants
1. Will know the basic principles of ethics and how these lead to geoethics
2. Will be aware of the dilemmas involved in making geoethical decisions
3. Will have gained some experience in taking a geoethical approach to real world cases
Course Content: (provisional):
1. From Ethics to geoethics: definition, values, tools
2. Responsible conduct of research and professionalism
3. Tools for confronting (geo)ethical dilemmas
4. Geoethics for society: sustainable development and responsible mining
5. Geoethics in natural hazards
6. Education challenges in geoethics
7. Geoethics in geoscience communication

Citizen science (the involvement of the public in scientific processes) is gaining momentum across multiple disciplines, increasing multi-scale data production on Earth Sciences that is extending the frontiers of knowledge. Successful participatory science enterprises and citizen observatories can potentially be scaled-up in order to contribute to larger policy strategies and actions (e.g. the European Earth Observation monitoring systems), for example to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate as citizen stewards in decision making, helping to bridge scientific disciplines and promote vibrant, liveable and sustainable environments for inhabitants across rural and urban localities.
Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Technology, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review. Before 2003, the term Open Access was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. Both open science and citizen science pose great challenges for researchers to facilitate effective participatory science, yet they are of critical importance to modern research and decision-makers.
We want to ask and find answers to the following questions:
Which approaches and tools can be used in Earth and planetary observation?
What are the biggest challenges in bridging between scientific disciplines and how to overcome them?
What kind of participatory citizen scientist involvement (e.g. how are citizen scientists involved in research, which kind of groups are involved) and open science strategies exist?
How to ensure transparency in project results and analyses?
What kind of critical perspectives on the limitations, challenges, and ethical considerations exist?
How can citizen science and open science approaches and initiatives be supported on different levels (e.g. institutional, organizational, national)?

Scientific understanding of all erosional physical processes controlling soil detachment, transportation, and deposition is vital when developing methods and conservation alternatives to minimize the impacts associated with soil degradation and support decision making.
This session will discuss the latest developments in soil erosion and closely associated land degradation processes in agriculture, forest and rangelands. Providing space for presenting and discussing:
• measurements - from rill to gully erosion, by means of field essays or laboratory experiments;
• monitoring - short to long-term assessments, by mean of local assessments or remote sensing techniques;
• modelling approaches – from plot to global scale, addressing current and future land and climate change demands;
• mitigation and restoration – to address on-site and off-site impacts on soils and water.
Our main objective is to scientifically discuss soil erosion processes and impacts but also to explore strategies that may help land stakeholders (farmers, land managers or policy makers), and support the ongoing initiatives aiming for land degradation neutrality by 2030 and the upcoming UN Decade on Ecosystem Restoration (2021-2030).
Soil has a tremendous potential to help mitigate climate change and contribute to most of the United Nations’ Sustainable Development Goals (SDGs), as expressed in the recent IPCC report on climate change and land. However, it is challenging to adapt and improve management practices for maximizing this potential, particularly when the main focus is to explore other services provided by soils, such as productivity. This is even more challenging considering the degradation status and/or risk of degradation of several soils worldwide, driven by anthropogenic activities (e.g. intensive agriculture and forestry, urbanization). The loss of organic matter and erosion are just a few examples of soil threats limiting climate change mitigation. Yet, increasing concerns have been devoted to restoring degraded land and soil in order to achieve Land Degradation Neutrality target, with impacts on increasing carbon storage. Over the last years, there has been an increasing interest on the potential of the soil to contribute to climate change mitigation and carbon neutrality. This has been noticed through several national and international initiatives, at civil (e.g. "4 per 1000" initiative) and political (e.g. Green Deal) level, and the establishment of partnerships (e.g. European Joint Programme SOIL).
This session aims to discuss the potential of soils to contribute to climate neutrality. We welcome recent research and advances on the topic, including experimental and modelling studies, and contributions addressing the following subjects:
• Short- and long-term changes on soil carbon stocks under different land uses, and their link with management and soil degradation processes;
• Impact of management practices and soil conservation techniques on soil carbon sequestration;
• Soil-water-plant-atmosphere interaction under different soil and weather conditions and climate variation;
• Impact of climate change on Land Degradation Neutrality, and interactions between Climate Neutrality and Land Degradation Neutrality;
• Integration of IoT into soil science to better support soil-related decision-making processes in achieving climate neutrality;
• Improving governance of soil sustainable management as a necessary condition for climate change mitigation and adaptation.
Global warming is unequivocal: the frequency and intensity of heavy precipitation events increased since the mid-20th century in all regions in which observational data were sufficient for trend analysis. And heavy precipitations and related effects are projected to intensify and be more frequent in most regions.
In this framework, particular attention should be paid to all the ground events triggered by rainfall, among which landslides and soil erosion.
Changes in temperature also have been shown to affect the hydraulic and mechanical behavior of soils and rocks in multiple ways, suggesting the importance of monitoring and modelling thermal variables alongside the hydraulic ones.
The influence of climate variables on the triggering, frequency, and severity of slope failures and soil erosion can be different according to the area, the time horizon of interest, and the specific trends of weather variables. Similarly, land use/cover change can play a pivotal role in exacerbating or reducing such hazards.
Thus, the overall impacts depend on the region, spatial scale, time frame, and socio-economic context addressed. However, even the simple identification of the weather patterns regulating the occurrence of such phenomena represents a not trivial issue, also assuming steady conditions, due to the crucial role played by geomorphological details. To support hazards’ monitoring, predictions, and projections, last-generation and updated datasets with high spatio-temporal resolution and quality - as those from the Copernicus Services’ Portals - are useful to feed models, big-data analytics, and indicators’ frameworks enabling timely, robust, and efficient decision making.
The Session aims at presenting studies concerning ongoing to future analysis on the impact of climate change on landslide triggering and dynamics, and soil erosion hazard, across different geographical contexts and scales. Either investigations including analyses of historical records and related climate variables, or modeling approaches driven by future climate exploiting downscaled output of climate projections are welcome. Studies assessing variations in severity, frequency, and/or timing of events and consequent risks are valuable.
Moreover, a focus on all aspects of landslide thermo-hydro-mechanics, from experimental studies to field and remote-sensing monitoring, from microstructural analyses to geomechanical modelling at various spatial and temporal scales, is proposed.
The Plateau-Mountain is widely distributed ecologically vulnerable area in the world. Due to the complication of its vertical zonality, the natural environment differentiated obviously, combined with the steep slope cultivations, leading to severe soil erosion and land degradation in these regions. To promote agricultural economic development, how to avoid the high rate of soil loss becomes the key environmental issue in the Plateau-Mountain areas. This session will discuss: 1) soil erosion processes and its environmental effect, 2) measures and techniques of soil conservation and vegetation restoration, 3) the key limiting factors of ecological restoration, and 4) balances between the fragile ecology protection and agricultural development in the Plateau-Mountain region.

Soils and palaeosols develop under the influence of various environmental factors that produce specific soil features, thus keeping a memory of both current and past environments. They are valuable archives of human activities that shaped environments and affected soil formation over the Holocene period. They can be studied to reconstruct environmental factors that were present during the time of their formation, and to disentangle the relative influences of different environmental conditions, both local and regional, on soil formation. Despite the increasing consideration of palaeosols in sedimentary successions, studies linking pedogenesis and sedimentary processes are still underrepresented. Anthropogenic soils in archaeological settings provide valuable archives for geoarchaeological studies, with their stratigraphy and properties reflecting settlement life cycles (occupation, abandonment, and reoccupation) and land-use history. Land-use legacy soils also have enormous potential for process-related research such as studying the long-term effects on the organic and inorganic carbon budget, physical compaction, aggregation, formation of anthropogenic pedofeatures and more.
This session is open for all contributions focused on the study of palaeosols, anthropogenic soils, and anthropogenically-affected soils, in particular on:
- The use of palaeosols and land-use legacy soils as records of present and former environments, both local and regional;
- Palaeosols and anthropogenically-affected soils and their relationships with sedimentary processes;
- Anthropogenic soils and palaeosols in archaeological contexts;
- The methodological progress in the study of soil records (for example, advances in biochemical, geochemical, and micromorphological (sub-)microscopic techniques in palaeopedology, in the interpretation of palaeoenvironmental data such as biomarker and isotope data, in remote sensing or modelling methods used to map and analyze spatial patterns of palaeosol and land use legacy soil distribution);
- Predictions of future soil changes as a result of changes in environmental conditions and/or land-use, based on observed past soil responses to environmental changes.

Documenting the diversity of human responses and adaptations to climate, landscapes, ecosystems, natural disasters and the changing natural resources availability in different regions of our planet, cross-disciplinary studies in Geoarchaeology provide valuable opportunities to learn from the past. Furthermore, human activity became a major player of global climatic and environmental change in the course of the late Quaternary, during the Anthropocene. Consequently, we must better understand the archaeological records and landscapes in context of human culture and the hydroclimate-environment nexus at different spatial and temporal scales. This session seeks related interdisciplinary papers and specific geoarchaeological case-studies that deploy various approaches and tools to address the reconstruction of former human-environmental interactions from the Palaeolithic period through the modern. Topics related to records of the Anthropocene from Earth and archaeological science perspectives are welcome. Furthermore, contributions may include (but are not limited to) insights about how people have coped with environmental disasters or abrupt changes in the past; defining sustainability thresholds for farming or resource exploitation; distinguishing the baseline natural and human contributions to environmental changes. Ultimately, we would like to understand how strategies of human resilience and innovation can inform our modern strategies for addressing the challenges of the emerging Anthropocene, a time frame dominated by human modulation of surface geomorphological processes and hydroclimate.

Soil structure is essential for soil biota and soil functioning. But its study remains difficult because of its heterogeneity in space and time. To understand the interactions between soil structure and soil biodiversity, a strong interdisciplinary approach merging soil physics, soil ecology and soil chemistry is needed. Soil structure defines the myriad of microhabitats that host the unparalleled biodiversity observed in soils. The micro-gradients in oxygen, moisture, nutrients and organic compounds act as ecological filters for soil biota and define soil functioning. The soil structure is also highly variable in time, being constantly re-modelled by numerous factors such as the alternation of wet and dry cycles, the activity of the soil biota, especially plant roots and ecosystem engineers (e.g. microbes, notably filamentous fungi stabilizing aggregates, soil macrofauna, etc.), and the input of fresh organic matter.
In this session, we invite interdisciplinary contributions on: (i) the formation and spatiotemporal variability of the soil structure, and on (ii) the role of the soil microhabitat in determining soil biodiversity. Field, experimental and modeling approaches are welcome. The ultimate aim is to understand how soil structure, from micro-architecture to macropores, emerges from interactions within soil, and how it determines the outcome of soil processes (e.g mineralization) that have an important outreach for plants (e.g through mycorrhizae for example).
Soil is the habitat for a myriad of organisms. These include soil fauna who are crucial in providing soil related ecosystem services, often through their interaction with microorganisms and plants. Soil fauna encompass a wide diversity of organisms including protozoa, nematodes, enchytraeids, microarthropods, as well as large invertebrates (e.g., earthworms, beetles). Variation in soil properties and climate result in a heterogeneous distribution of soil fauna across the globe. Soil fauna substantially affect litter decomposition and soil organic matter formation, and are key agents in soil structure formation. Their activity can result in the production of decomposition by-products which are still poorly chemically and physically characterized, despite the fact that they are a springboard for soil organic matter formation as well as a potential source of nutrients. Soil fauna therefore have a central role in soil biogeochemical cycling.
In this session, we welcome contributions on a wide range of topics related to the effect of soil fauna on biogeochemical cycling (e.g., organic carbon storage, nutrient availability, gas emissions) in interaction with soil properties (e.g., aggregation, bioturbation, biopores, weathering). We call for studies on the effect of soil fauna on litter decomposition and the analyses of the decomposition by-products, as well as studies that tackle the interactions between soil fauna, plants and microorganisms. We are especially interested in studies that provide mechanistic (rather than stochastic) links between faunal activity and ecosystem services. Studies can cover various scales (from microscale to landscape) and approaches using physical fractionation, molecular methods (e.g., amino sugars, lipids, PLFAs, DNA), and imaging (e.g., SEM, TEM, nanoSIMS, µCT), spectroscopic and/or isotopic techniques. We also encourage contributions investigating the changing role of soil fauna under climate change, land use changes and land cover change.

Soil organisms comprise a large fraction of global terrestrial diversity and are responsible for essential ecosystem functions and services, such as determining plant productivity, nutrient cycling, organic matter decomposition, pollutant degradation and pathogen control. However, soil biodiversity and its functional roles are determined by the abiotic surrounding. As such, anthropogenic influences including urbanization, land-use change, pollution, invasions etc., alter soil biodiversity and its functions. Here we aim to showcase recent advances on how anthropogenic drivers determine soil biodiversity and how that subsequently feeds-back to ecosystem functions and human health.
This session invites contributions that showcase examples of: 1) Mapping soil biodiversity under different anthropogenic influences; 2) Understanding the functional implication of anthropogenic changes of soil biodiversity; 3) Protecting and restoring biodiversity in anthropogenically altered soils; 4) Manipulating soil biodiversity to increase ecosystem functions and human health under anthropogenic factors.
Anthropogenic greenhouse-gas emissions are drastically shaping global climate, increasing temperatures and contributing to more frequent extreme weather events. Terrestrial ecosystem responses to climate change can induce a large feedback via the control of biogeochemical cycles, for instance by regulating carbon fluxes that are 10 times larger than human emissions. A large portion of carbon and nutrient cycling is controlled by soil processes, in which microorganisms play a central role. Soil microbial communities and their physiological traits are, in turn, influenced by both gradual climate changes and more extreme short-term weather events. Thus, understanding the impacts of climate on soil microbial communities and microbe-mediated processes is critical for improving predictions of the resistance and resilience of terrestrial ecosystems in the future.
This session aims to elucidate the impacts of different climate scenarios on soil microbial communities and biogeochemical cycling, and their feedback to climate change. We will focus on different aspects of climate change, ranging from gradual changes such as increasing atmospheric CO2 or temperature, to the effects of more extreme weather events such as heatwaves, drying-rewetting cycles or floods. We invite studies on the resilience and associated recovery dynamics of soil biota to the mentioned environmental disturbances, as well as on their resistance or adaptation mechanisms. Studies with a focus on links between microbial community composition and function, as well as interactions between soil microorganisms, plants and fauna, are particularly welcomed. We aim to connect researchers from different disciplines and to create a discussion platform to review the current state-of-the-art, identify knowledge gaps, share ideas, and tackle new challenges in the field.
Microbial hotspots in soils such as the rhizosphere, detritusphere, biopores, hyphasphere, aggregate surfaces, pore space and etc, are characterized by high activity and fast process rates resulting in accelerated turnover of soil organic matter and other microbial functions (e.g. nutrient mobilization, litter decomposition, respiration, organic matter stabilization, greenhouse gas emission, acidification, etc.). The intensity of microbial and SOM turnover as well as nutrient cycling in such hotspots is at least one order of magnitude higher than in the bulk soil.
This session invites contribution to: 1) Various aspects of microbial activity, interactions, communities composition and distribution in hotspots; 2) Factors influencing (micro)biological nutrient (re)cycling including biotic and abiotic controls (e.g. climatic extreme, warming, drought, etc) are strongly encouraged; 3) The session will also present and discuss new developments to assess the crucial microbial mechanisms that underpin biogeochemical processes in hotspots (e.g. approaches assessing the variability in soil activity within the soil matrix, notably focusing on microbial molecular analysis and imaging methods); 4) Combination of experimental and theoretical approaches to predict the fate and functions of microorganisms in hotspots are highly appreciated.

The rhizosphere is regarded as the soil compartment with the highest level of nutrient flux through a multitude of interactions between plants, soil, and (micro)biota. Roots and associated (micro)organisms interact with heterogeneous soil environments that provide habitats for biota on various scales. High metabolic activity and nutrient cycling can be observed from single root tips to whole root systems which makes the rhizosphere of central importance for ecosystem functioning.
The main knowledge-gaps in rhizosphere research are related to the difficulty in mechanistically linking the physical, chemical and biological processes, taking place at different scales (nm to cm) in the rhizosphere and to the challenge of upscaling these processes to the scale of the root system and the soil profile. The key for overcoming these knowledge gaps is to understand rates of matter flux, and to link the spatial arrangement of the different interconnected components of the rhizosphere with their temporal dynamics. This requires concerted efforts to combine methods from different disciplines like plant genomics, imaging, soil physics, chemistry and microbiology.
We welcome experimental and modelling studies on rhizosphere functioning that aim at revealing spatial gradients of e.g. functional biodiversity of microorganisms, uptake and release patterns by roots, soil structure modification by root growth (and vice versa) as well as feedbacks between those processes in order to improve our mechanistic understanding of emerging properties like water acquisition, nutrient cycling, plant health, soil structure development and feedbacks among them.

Soil organic matter (SOM) plays a vital role not only in soil fertility and quality (by providing a number of physical, chemical, and biological benefits), but also in carbon cycling. SOM contains a vast range of diverse organic structures, and also a living component (microorganisms) with various residence times that define the central role SOM plays in the soil. The decline of SOM represents one of the most serious threats facing many arable lands of the world. One of the efficient approaches to increase SOM content and decrease land degradation is the application of organic amendments, such as crop residues and animal manures. Nowadays, organic amendments originate from many kinds of organic wastes, which are being increasingly produced mainly by farms, agro-food industries, municipalities, and energy plants. Besides serving as a source of organic matter and plant nutrients, these materials may contribute to reduce soil contamination, erosion, and desertification, as well as mitigate climate change. At the same time, a safe and useful application of organic amendments requires an in-depth scientific knowledge of their nature and impacts on the SOM pools and factions, soil-plant system, as well as on the surrounding environment.
This session will combine the current research and recent advances on the use of organic amendments in modern agriculture as well as for the restoration of degraded soils. Field and laboratory studies focused on the effects of management practices, climate change, environmental conditions, soil properties are highly welcome.

Soil organic matter (SOM) is well known to exert a great influence on physical, chemical, and biological soil properties, thus playing a very important role in agronomic production and environmental quality. Globally SOM represents the largest terrestrial organic C stock, which can have significant impacts on atmospheric CO2 concentrations and thus on climate. The changes in soil organic C content are the result of the balance of inputs and losses, which strongly depends on the processes of organic C stabilization and protection from decomposition in the soil. This session will provide a forum for discussion of recent studies on the transformation, stabilization and sequestration mechanisms of organic C in soils, covering any physical, chemical, and biological aspects related to the selective preservation and formation of recalcitrant organic compounds, occlusion by macro and microaggregation, and chemical interaction with soil mineral particles and metal ions.

Soil organic matter (SOM) contains a vast range of diverse organic structures, and also a living component (microorganisms) with various residence times that define the central role SOM plays in fundamental physico-chemical and biological processes in the soil. With human activities severely affecting SOM dynamics (through inappropriate agricultural practices, erosion, forest fires, climate change), a better understanding of SOM transformation is urgently needed as this has further implications for carbon (C), nitrogen (N) and phosphorus (P) cycling and biogeochemical processes affecting global CO2 emissions. Detailed analyses of SOM composition can highlight the role of selective preservation mechanisms and sources of SOM, for example, and how these are modified and influenced by physical and chemical interactions.
To trace SOM sources and the composition of microbial communities a broad set of biomarkers is used: lignin compounds (C sources from plant communities), cutin and suberin (above- vs belowground plant biomass), non-cellulose sugars (plant vs microbial C), DNA (microbial community composition), phospholipid fatty acids (living microbial groups), ergosterol (fungal biomass), amino sugars (microbial necromass and its sources) are just a few examples. Coupling analysis of these biomarkers with 13C/14C/15N/33P/18O labeling allows tracing these elements through the microbial food web and the soil element cycles. It, thus, reveals turnover of organics and their stabilization in SOM, C, N and P recycling in microbial biomass, growth rates of bacteria and fungi, and microbial metabolic pathways.
We encourage the submission of studies (especially from early-career students) employing new methods or applications of identification and quantification of biomarkers to study: i) the fate and turnover of organic and inorganic inputs in soil (from uptake and utilization by microorganisms to stabilization in SOM), ii) the mechanisms and sources of SOM formation and its turnover, and iii) to link microbial recycling of different elements (C, N and, P) from fresh organic material or during reworking SOM. Field and laboratory studies focused on the effects of management practices, climate change, environmental conditions, soil properties are highly welcome. We also encourage contributors to present and discuss analytical challenges that remain due to environmental and analytical uncertainty.

Climate change has already started to affect dynamic feedbacks between plant, soil, and microbial communities and thus strongly influences terrestrial biogeochemical cycling. In this session we address the questions: What is the impact of changing environmental conditions on the plant-soil system, and the resulting effects on soil biogeochemistry? And how do we represent soils in (global) models and upscale experimental data using process-based understanding of the controls on biogeochemical cycles? In this session we seek contributions addressing how biogeochemical cycles in soils vary across gradients in climate, vegetation, and soil properties, and how they may respond to future changes.
We invite contributions from manipulative field experiments, observations in natural-climate gradients, and modelling studies that explore climate change impacts on plant-soil interactions, biogeochemical cycling of C, N, P, microbial diversity and decomposition processes, and deep -soil biogeochemistry. Researchers are encouraged to present their empirical and/or modeling studies addressing soil dynamics along geochemical and climatic gradients. Submissions that adopt novel approaches, e.g. molecular, isotopic, or synthesize outputs from large-scale, field experiments focusing on plant-soil-microbe feedbacks to warming, wetting, drying and thawing are very welcome.

Water, energy, and solute transport in the vadose zone occur in a variety of scales. How the processes occurring at the small scale control and constrain the large scale responses is a long-standing challenge in vadose zone hydrology. Description of several processes such as evaporation, infiltration, soil-root-water interactions as well as soil characteristics such as conductivity and mechanical impedance rely on small scale measurement which are used to model processes occurring at scales much larger than the measurement scales. The utilization of advanced experimental and modelling tools are required to close the hierarchical gap present in different scales. Within this context, the focus of this session is on measurement or modeling approaches to parametrize or conceptualize soil physical, thermal, hydraulic, and mechanical properties across different spatial and temporal scales and resolutions from the size of a pore to the sample or field scale. We invite contributions related to:
- Measuring soil physical and chemical properties in the lab, field, or watershed utilizing a variety of tools ranging from micro-scale imaging to local measurement by soil sensors, drowns, radars, remote sensing, etc.
- Analytical, empirical, statistical, or numerical modeling approaches that link soil processes across scales, upscaling and downscaling experiences to tackle heterogeneity challenges for the description of vadose zone processes such as evaporation, infiltration, land-atmosphere interactions, and subsurface mass and energy fluxes.
- Modeling or measurement campaigns concerning the spatiotemporal changes of vadose zone properties at different scales induced naturally or by human activities such as freezing-thawing circles, climate change, heavy agricultural machinery, and agricultural practices.

Soils largely contribute to sustain agro-systems production and provide many ecosystem services that are essential for addressing sustainable land and water management. Management of both soil and water resources is a primary socio-economic concern that requires a detailed description of the physical and biological process that occur into the soil-plant-atmosphere continuum system. Nevertheless, measuring soil state variables and hydraulic parameters is often difficult due to the many complex nonlinear physical, chemical and biological interactions that simultaneously control the transfer of heat and mass.
Infiltration experiments have been proposed as a simple mean to estimate soil hydraulic properties but their effectiveness is hampered by the effects of spatio-temporal variability across scales. High-resolution measurements of soil state variables, both over space and time, are thus crucial to describe and analyze soil hydraulic properties adequately.
The session focuses on the principles, capabilities, and applications of different techniques for monitoring state variables of soil and estimating soil hydraulic properties from infiltration experiments. Specific topics include, but are not limited to:
- Multiple measurement techniques and modelling approaches for determining state variables of soil;
- Innovative soil-water measurements techniques for linking the interactions of soil with plant and atmosphere compartments;
- Field infiltration techniques from a wide variety of devices in combination with dielectric and geophysical methods (i.e., TDR, FDR, GPR, ERT, etc.);
- New or revisited numerical and analytical models to account for physical, chemical and biological interaction in the soil-water flow models (multiple-porosity, permeability, hydrophobicity, clogging, shrinking-swelling, or biofilm development);
- Use of pedotransfer functions based on limited available in-situ measurements to estimate parameters that describe soil hydro-physical and thermal characteristics;
- Multi-data source methodologies also in combination with modelling for assessing the soil physics dynamics at different temporal and spatial scales.
We welcome contributions from simulated and real data investigations in the laboratory or field-based experiments, successful and failed case studies, and the presentation of new and promising modeling approaches, scenarios, and techniques.
Preferential and non-uniform flows are induced by biotic (e.g. earthworms and roots) and abiotic factors and processes (e.g. wet-dry and freeze-thaw cycles, lithology and structure) as well as anthropogenic activities (e.g. tillage and cultivation methods in agricultural land, man-made landforms from waste rock dumping and disposal strategies in mining). The understanding of preferential flow is of premium importance in relation to soil hydrology, as it can move a considerable amount of water and solutes in porous media. Preferential flows can occur spatially from the pore scale, to entire catchments, across large regions. Temporally, the preferential processes can change during hydrological events, from within hours to seasonal events, and across inter-annual variations of years.
This session welcomes studies on experimental and theoretical challenges to identify, quantify, and model the key physical factors and processes that are responsible for preferential flows in porous media across scales (from pore scale to catchment scale). Contributions are welcome to reflect on experimental studies, novel approaches and advances in solutions to:
• Understand the geometry and connectivity, formation and dynamics of fissure, fractures and macropores and its effect on preferential flow;
• Understand the effect of physical processes and geochemical processes on the dynamics of macropores and fracture networks;
• Unpacking the pore structure of soil using new methods and approaches, including the use of non-Newtonian fluids, for improved characterization of heterogeneous soils and the advancement of flow and transport modeling.
• Effects of preferential flows within the soil-plant-atmosphere continuum and their consequence for solute, nutrient, or contaminant transport in the saturated and unsaturated zone;
• Coupling the physical processes of preferential flows and geochemical processes for improving the understanding of solute sorption and desorption, mineral precipitation and dissolution;
• Modelling of the effect of preferential flow on mass transport across scales, from pore scale to pedon scale and entire catchments and landscapes.
Soil structure and its stability determine soil physical functions and chemical properties such as water retention, hydraulic conductivity, susceptibility to erosion, and redox potentials. These soil physical and chemical characteristics are fundamental for biological processes, among them root penetration and organic matter and nutrient dynamics. The soil pore network forms the habitat for soil biota, which in turn actively reshape it according to their needs. The soil biota, root growth, land management practices like tillage and abiotic drivers (e.g. wetting/drying cycles) lead to a constant evolution of the arrangement of pores, minerals and organic matter. With this, also the soil functions and properties are perpetually changing. The importance of the interaction between soil structure (and thus soil functions) on one side and soil biology, climate and soil management on the other, is highlighted by recent research outcomes, which are based on advanced imaging techniques, novel experimental setups and modelling approaches. Still, present studies have barely scratched the surface of what there is to discover.
In this session, we are inviting contributions on the formation and alteration of soil structure and its associated soil functions over time. Special focuses are on feedbacks between soil structure dynamics and soil biology as well as the impact of mechanical stress exerted by heavy vehicles deployed under land management operations. Further, we encourage submissions that are exploring new modelling concepts, integrating complementary measurement techniques or aim at bridging different scales.

The soil is a key system of the biosphere that supports the existence and development of human civilization. However, the growing anthropic activities are accompanied by an expansion of soil pollution. From a geochemical point of view, anthropic activities lead to the emergence of a new state of the biosphere - the noosphere, when anthropogenic chemical elements and their compounds are added to natural soil. This determines the current spatial heterogeneity of the chemical composition of the soil and vegetation cover. Such an alteration to soil composition/properties can cause negative biological impacts on both native and introduced species in local biocenosis, as well as the emergence of endemic diseases among plants animals, and humans. Human diseases can be aggravated by the fact that Homo sapiens evolving as a species under certain environmental/geochemical conditions inherited a corresponding need for certain dietary elements to maintain homeostatic regulation. As a result, people, like other organisms, need to ingest elements in the correct amounts, otherwise, they suffer from a deficiency or excess of these elements. A negative reaction may occur when the species’ natural metabolism fails to compensate for this imbalance in the life cycle. Therefore, complex studies on the identification, spatial distribution, migration, and concentration of the contaminants in soils, plants, and surface and groundwater in urban, mining, agricultural/forest, and natural areas, as well as its biological effects, is an essential issue and important task for 1)identification of zones of different natural and man-made ecological risks; 2)understanding contaminants’ pathways and impact, and 3)mitigation or elimination of negative biological effects, including the spread of non-communicable endemic diseases.
At this session, participants are invited to present their new data on soil pollution, as well as to show ideas and approaches to the solution of the problem of soil reclamation, to show results that contribute to modern knowledge on the ecological and geochemical assessment of various regions of the world exposed to anthropic geochemical impact, including industrial pollution, transport, mining and use of fertilizers and biocides. We also welcome presentations devoted to methodological problems on soil pollution assessment, the creation of ecological and geochemical databases, and compiling risk maps. We hope that live discussion will contribute to each study.

Soil pollution is a global threat which seriously affects biodiversity in (agro)ecosystems and compromises the quality of the food and water. Besides naturally elevated levels of potentially toxic elements and compounds (elevated mineralization of soils, accumulation of phenolics), most contaminants originate from human activities such as industrial processes and mining, poor waste management, unsustainable farming practices and accidents.One of the most important issues in pollution research is the assessment and evaluation of pollution including assessment and evaluation of the distribution of pollutants, mobility, chemical speciation as well as evaluation of the probability of soil-plant transfer and accumulation in plants.
This session aims to bring together contributions of all aspects of biogeochemical research related to soil pollution risk assessment including (but not limited to) assessment of pollution status, geochemical mapping, analysis of element cycling within soils and ecosystems as well as ecotoxicological considerations.
We welcome presentations of laboratory and field research results as well as theoretical studies. We intend to bring together scientists from multiple disciplines. Young researchers are especially encouraged to submit their contributions.
Soil pollution is a worldwide problem, which can result in a negative impact in (terrestrial) ecosystems, surface and groundwater, and the food chain. According to the European Commission, there are around 2.8 million soil pollution events contributing to soil pollution. Of these, 25 % have been identified and registered, but only 5% need mitigation strategies. In order to address soil pollution and develop preventive and mitigation strategies, it is necessary to invest in (i) the identification and characterization of these sites, from contaminant identification to ecosystem characterisation, and (ii) the identification of potential solutions. This requires linking new strategies (e.g. machine learning, artificial intelligence, digital data mapping) with natural solutions (e.g. soil-microorganisms-root-plant interaction). We welcome our colleagues to present their latest and ongoing findings and look forward to establishing new partnerships to create holist strategies that can help to prevent, assess and mitigate soil pollution consistently and swiftly.
This session will focus on the last achievements (lab-scale, field-scale, simulations) regarding the fate of Per- and PolyFluoroAlkyl Substances (PFAS) in soil and groundwater and the development of relevant remediation technologies. Recent researches have revealed that PFAS move faster and remain for longer periods inside soils than previously recorded, while their recalcitrance and very low concentration stimulate the investigation of advanced treatment technologies for the in situ/ex situ remediation. The presence of PFAS in soil and groundwater may be proved really dangerous for human health, and innovative tools are required for the detection, prediction and mitigation of PFAS in subsurface.
This session will showcase contributions covering research conducted in this area of research describing experimental, observational, and theoretical studies. Topics of interest are (although not limited to) causes and impacts of land degradation and remedial actions and strategies for restoration at local, regional or global scales.

The session gathers geoscientific aspects such as dynamics, reactions, and environmental/health consequences of radioactive materials that are massively released accidentally (e.g., Chernobyl and Fukushima nuclear power plant accidents, wide fires, etc.) and by other human activities (e.g., nuclear tests).
The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Thus, the radioactive contamination problem is multi-disciplinary. In fact, this topic involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic and ecosystem, and its relations with human and non-human biota. The topic also involves hazard prediction and nowcast technology.
By combining 35 years (> halftime of Cesium 137) monitoring data after the Chernobyl Accident in 1986, 10 years dense measurement data by the most advanced instrumentation after the Fukushima Accident in 2011, and other events, we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents.
The following specific topics have traditionally been discussed:
(a) Atmospheric Science (emissions, transport, deposition, pollution);
(b) Hydrology (transport in surface and ground water system, soil-water interactions);
(c) Oceanology (transport, bio-system interaction);
(d) Soil System (transport, chemical interaction, transfer to organic system);
(e) Forestry;
(f) Natural Hazards (warning systems, health risk assessments, geophysical variability);
(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).
The session consists of updated observations, new theoretical developments including simulations, and improved methods or tools which could improve observation and prediction capabilities during eventual future nuclear emergencies. New evaluations of existing tools, past nuclear contamination events and other data sets also welcome.

Soils sustain complex patterns of life and act as biogeochemical reactors producing and consuming a large amount of gas molecules. They play a fundamental role in the temporal evolution of the atmospheric gases concentration (greenhouse gases, biogenic volatile organic compounds, nitrous acid, isotopic composition…) and they modulate the soil pore gas concentrations affecting many soil functions, such as root and plant growth, microbial activity, and stabilization of soil organic carbon. Gases production, consumption and transport in the different soil types have then some important ecological implications for the earth system.
The factors affecting the soil gas processes range from physical soil structure (porosity, granulometry,…), type and amount of living material (microbiota, root systems), soil chemistry properties (carbon and nitrogen contents, pH,…) and soil meteorological conditions (temperature, water content,…). A large mixing of different scientific backgrounds are therefore required to improve the knowledge about their influence which is made even more difficult due to the very large spatial heterogeneity of these factors and the complexity of their interactions.
This session will be the place to present and exchange about the measurement techniques, data analyses and modelling approaches that can help to figure out the temporal and spatial variability of the production/consumption and transport of gases in soils. In addition to mechanisms related to carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), including the geochemical ones, the abstracts about volatile carbon compounds produced by plant and microbial or Helium and Radon geogenic emissions production are welcome
A special attention will be given to the researches including special water situations as edaphic drought or waterlogged soils

Soil is one of the most important substances on Earth. Information on our planet’s soil resources is indispensable to a number of practical applications related to both society and ecosystems. Globally, Earth’s soils resources monitoring has developed into very important and urgent research directions, especially in the face of climate change.
Geoinformation technologies, primarily of Earth Observation (EO), Geographical Information Systems (GIS), GPS/GNSS along with Big Data, Cloud Computing, the Internet of Things, Deep Learning and Artificial Intelligence can successfully support sustainable soil management. The rapid growth in the geoinformation sector combined with the continuous availability of new geospatial data provides important support to analyze soil characteristics and their three-dimensional patterns. As such, it allows exploiting interdisciplinary information and datasets to better understand soil functions and monitoring land changes towards more sustainable soils management and sustainability, although the capacity to predict the physical and morphological features of soils and to integrate this information in prediction of other relevant soil properties is still limited.
In this session, we welcome contributions covering inter and transdisciplinary research through theoretical and applied studies, on the application of all range of geoinformation technologies as an opportunity for innovation and competitiveness for example in agricultural soil management, precision agriculture and precision livestock farming.
Soils play an essential role in supplying numerous ecosystem services such as food regulation, nutrient regulation, erosion regulation, water purification, carbon sequestration, food and fibre provisioning. Therefore, they play an essential role in human wellbeing. The unsustainable use of soil is one of the significant causes of land degradation due to soil erosion, sealing, pollution, salinization and wildfires—this trigger two of the most critical challenges of our time, biodiversity loss and climate change. A global effort is needed to tackle this unprecedented degradation trend caused by human actions, to maintain healthy soil functions and the services provided, especially in a growing consumption and population that are exhausting the ecosystem resources and contributing to climate change. It is paramount to develop creative solutions to make soil management more sustainable and maintain soil health.
In this session, we welcome contributions covering inter and transdisciplinary research through observational, theoretical and applied studies on soil ecosystem services and soil function in the context of a changing global environment. Topics of interest are (although not limited to): 1) Impacts of soil degradation on soil function and ecosystem services and 2) Soil conservation and restoration actions for maintaining ecosystem services (including research, management, education and policy).

It is wildly accepted that the functions of soil are intimately linked to its structure and state of aggregation. Water retention characteristics, ventilation, fluids-flow, and transport of mobile material - from the solutes and colloids to suspended particles - depends intricately on the properties of the void network structure and the composition and properties of the solid-fluid interfaces therein. Extent and rates of organic matter storage, nutrient supply, contaminant retardation, but also microbial colonization, root penetration and hyphae exploration patterns are part of a complicated feedback loop that not only creates structure but results in its change in space and time. Processes and mechanisms that result in structure formation and dynamics in soil are intensively studied and vividly debated: In particular the role of aggregates and aggregation is discussed intensively. With the advent of sophisticated spectroscopic, microscopic, and tomographic techniques that enable to study structure, composition and interface properties at the submicron scale even down to the atomic scale, testing hypothesis on the co-evolution of structure, properties and emerging function on soils from the atom to the pedon scale is rapidly progressing. In particular if techniques exploring void-interface structure and properties are combined with field observational data and experimental pedogenesis in a joint fashion, testing of hypothesis can much better be directed towards generalizable theories on the mechanistic linkage of structure and function in soils and their evolution during pedogenesis. With this symposium we aim to discuss and debate the recent achievements, current obstacles, and future research directions to contribute to a synoptic understanding of the relationship between soil architecture and functions across scales. We specifically invite contribution from the different fields of soil research employing one or, in a joint fashion, more than one approach of the variety of experimental, observational, instrumental and computational methods.

Biogenic volatile organic compounds (bVOCs) are global chemical signatures of life. bVOCs comprise chemically diverse gaseous compounds of biological origin and are emitted from and consumed in terrestrial ecosystems. We consider biological sources and sinks being mainly plants and soil life, especially the microbiota. bVOCs are receiving an increasing scientific interest since breakthroughs in analytics of compounds but also of plants and microbiota facilitate an integrative understanding.
bVOCs have various environmental functions. Some impact on the oxidative capacity of the troposphere, stratospheric ozone destruction, and contribute to aerosol formation. Others are involved in chemical signaling between plants, animals and microbes in terrestrial ecosystems and hence, connect organisms’ activities and behaviors beyond the canonical trophic foodweb theory. In the era of the anthropocene, land use and associated human forces alter bVOC flux dynamics by changing ecosystems and their properties.
Understanding bVOCs fluxes in and from terrestrial ecosystems has two conceptual dimensions. (a) They are ecological interaction signals and thus, are affecting ecological interactions and ecosystem functioning - which includes plant production in agriculture - and (b) they are relevant for atmospheric chemistry and thus land-atmosphere interactions. Both dimensions are inherently intertwined and can be seen as two sides of the same coin.
We would like to merge both dimensions in one single session at the EGU Biogeosciences Division to trigger discussions on future research perspectives - e.g. how to quantitatively determine and/or predict bVOC fluxes by considering interactions of biological actors. Also novel insights in the topic, and methodological developments and new approaches are highly welcomed.
The session is addressed to experimentalists and modellers working on air-land interactions from local to regional scales. The programme is open to a wide range of new studies in micrometeorology and related atmospheric and remote sensing disciplines. The topics include the development of new devices, measurement techniques, experimental design, data analysis methods, as well as novel findings on surface layer theory and parametrization, including local and non-local processes. The theoretical parts encompass soil-vegetation-atmosphere transport, internal boundary-layer theories and flux footprint analyses. Of special interest are synergistic studies employing experimental data, parametrizations and models. This includes energy and trace gas fluxes (inert and reactive) as well as water, carbon dioxide and other GHG fluxes. Specific focus is given to outstanding problems in land surface boundary layer descriptions such as complex terrain, effects of horizontal heterogeneity on sub-meso-scale transport processes, energy balance closure, stable stratification and night time fluxes, dynamic interactions with atmosphere, plants (in canopy and above canopy) and soils.

Viticulture is one of the most important agricultural sectors of Europe with an average annual production of 168 million hectoliters (54% of global consumption). The concept of “Terroir” links the quality and typicity of wine to the territory, and, in particular, to specific environmental characteristics that affect the plant response (e.g. climate, geology, pedology). The environmental factors that drive the terroir effect vary in space and time, as well as soil and crop management.
Understanding the spatial variability of some environmental factors (e.g. soil) is very important to manage and preserve terroirs and face the current and future issue of climate change. In this sense, it is important to stress that in the last decade, the study of terroir has shifted from a largely descriptive regional science to a more applied, technical research field, including: sensors for mapping and monitoring environmental variables, remote sensing and drones for crop monitoring, forecast models, use of microelements and isotopes for wine traceability, metagenome approach to study the biogeochemical cycles of nutrients.
Moreover, public awareness for ecosystem functioning has led to more quantitative approaches in evidencing the relations between management and the ecosystem services of vineyard agroecosystems. Agroecology approaches in vineyard, like the use of cover crops, straw mulching, and organic amendments, are developing to improve biodiversity, organic matter, soil water and nutrient retention, preservation from soil erosion.
On those bases, the session will address the several aspects of viticultural terroirs:
1) quantifying and spatial modelling of terroir components that influence plant growth, fruit composition and quality, mostly examining climate-soil-water relationships; 2) terroir concept resilience to climate change; 3) wine traceability and zoning based on microelements and isotopes; 4) interaction between vineyard management practices and effects on soil and water quality as well as biodiversity and related ecosystem services.
Organic farming is based on the natural cycles of energy and nutrients, and relies on the use of crop rotations, crop residues, compost and green manure. The International Federation of Organic Agriculture Movements (IFOAM) agrees to define the “Organic agriculture as a production system that sustains the health of soils, ecosystems and people. It relies on ecological processes, biodiversity and cycles adapted to local conditions, rather than the use of inputs with adverse effects".
This Scientific Session invites you to contribute with your experience in organic farming in relation to soil changes (biota, water, mineral and organic matter, erosion), soil productivity, plant protection, healthy food, food quality or socio-economic aspects. Studies focused on optimal energy efficiency, carbon and water footprint (with an emphasis in green and grey water), greenhouse gasses (GHC) and soil nutrient balancing as indicators of sustainable agricultural practices, are also welcomed. Research conducted on different continents will be shown in order to know the sustainability of organic agriculture under different environmental, social and economic conditions. All these studies could provide robust scientific basis for governmental agricultural policies development and decision tools for stockholders.

The state of forests across the world is an issue of great concern - forests are essential for various ecosystem functions but remain under enormous pressure from human land use. Forests regulate climate, hydrology, sequester carbon and provide various foods, medicines, timber and non-timber products. Considering these as essential ecological and social functions, the state of forests needs continuous monitoring. An understanding of the various factors and processes at play is crucial to ensure forest persistence in the face of environmental change and socioeconomic transformations. Multiple demands on forest, especially competing land uses, often threaten their existence. This session thus invites papers that analyse the state and dynamics of forests, investigate and differentiate how forests respond to changing ecological conditions, as well as the management and governance processes to sustain forests. We are particularly interested in methodological innovations in forest landscape research that address these points from both disciplinary and transdisciplinary approaches.
Soil is the largest carbon (C) reservoir in terrestrial ecosystems with twice the amount of atmospheric C and three times the amount in terrestrial vegetation. Carbon related ecosystem services include retention of water and nutrients, promoting soil fertility and productivity and soil resistance to erosion. In addition, changes in the soil C can have strong implications for greenhouse gas emissions from soil with implications in environmental health.
Drivers controlling C pools and its dynamics are multiple (e.g. land use/vegetation cover, climate, texture and bedrock, topography, soil microbial community, soil erosion rates, soil and other environment management practices, etc. ) and mutually interacting at various time and spatial scales. At the one time, rate of soil C loss can be high due to both climatic constrains or unsuitable management. Thus, investigating C dynamics include the adaptation of the management factors to the actual climate, the climate change and climatic extreme events to provide a better understanding of carbon stabilization processes and thus support decision making in soil management and climate adaptation strategies.
The present session highlights the importance of soil C changes, and the interaction among the mechanisms affecting C concentration and stocks in soil, including soil management. Discussion about proxies of measurement and modelling organic and inorganic C flows, concentration and stocks, with special emphasis to cropping systems and natural/semi-natural areas, is encouraged. These proxies should be approached at varying the availability of soil and environment information, including, e.g., soil texture, rainfall, temperature, bulk density, land use and land management, or proximal and remote sensing properties. Studies presented in this session can aim to a wealth of aims, including soil fertility, provision of ecosystem services, and their changes, and the implication for economy, policy, and decision making.
Types of contribution appreciated include, but are not limited to, definitive and intermediate results; project outcomes; proposal of methods or sampling and modelling strategies, and the assessment of their effectiveness; projection of previous results at the light of climate change and climatic extremes; literature surveys, reviews, and meta-analysis. These works will be evaluated at the light of the organisation of a special issue in an impacted journal
Wildfires are a worldwide phenomenon with many environmental, social, and economic implications, which are expected to escalate as a consequence of climate change and land abandonment, management, and planning, further promoting land degradation and decreasing ecosystem services supply.
The current situation demands from the scientific community the study of wildfire effects on the ecosystems and the development of integrated tools for pre- and post-fire land management practices that reduce the vulnerability to wildfires and their impacts. However, this research urges the attention not only from researchers, but also from stakeholders and policy-makers all over the world, since basic resources such as raw materials, water, and soils as well as habitats are at stake.
This session aims at gathering researchers on the effects of wildfires on ecosystems, from wildfire prevention to post-fire mitigation. We kindly invite laboratory, field, and/or modelling studies involving the following topics:
i. prescribed and/or experimental fires;
ii. fire severity and burn severity;
iii. fire effects on vegetation, soil and water;
iv. post-fire hydrological and erosive response;
v. post-fire management and mitigation;
vi. socio-economic studies on pre- and post-fire land management;
vii. fire risk assessment and modelling.

Exchange of greenhouse gases (GHGs) such as methane (CH4) and nitrous oxide (N2O) in forest ecosystems has traditionally focused on gas flux measurements from soil or between biosphere and atmosphere in the surface layer only. However, it has become evident that trees may play an important role in the net exchange of these GHGs in forests. Trees can contribute to ecosystem exchange by uptake and transport of soil-produced CH4 and N2O to the atmosphere, in-situ production and consumption of both gases in plant tissues, and alternation of carbon- and nitrogen-turn-over in adjacent soil. However, the contribution of these individual processes to the net ecosystem GHGs exchange is still unclear and seems to depend on many aspects as tree species, forest ecosystem type, environmental parameters and seasonal dynamics. Interactions between soil, vegetation and the atmosphere exert a crucial role controlling the global budget of these gases.
This session seeks to bring together scientists working on the exchange of CH4 and N2O in forest ecosystems at any relevant scale, and from the full climatic and hydrological forest range. We therefore welcome contributions on (i) production and consumption processes in soils and plant tissues; (ii) gas transport processes in soil-tree-atmosphere continuum; (iii) gas flux measurements on the forest floor, cryptogams, tree stems or at leaf and canopy level; (iv) micrometeorological measurements using flux towers, satellite, or modelling approaches that seek to integrate our understanding of CH4 and N2O exchange in forest ecosystems.

Dear colleagues and friends,
We are going to have a session dinner together on Wednesday, May 25 2022, from 8 p.m.
at the Brandauers Bierbögen (https://www.bierig.at/bierbogen/; The tables are reserved on Martin Maier).
The session dinner will be together with our colleagues from the session
SSS8.3 "Soil gases : production, consumption and transport processes".
We are looking forward to meeting you all in Vienna or online next week.
The interactions between plants and the environment play a prominent role in terrestrial fluxes and biochemical cycles, but we still lack a general understanding of how these interactions impact plant growth and plant access to soil resources particularly under deficient conditions. The main challenge arises from the complexity of both soil and plants. To address such a knowledge gap, an improved understanding and predictability of plant-related transfer processes are urgently needed.
Emerging experimental techniques such as non-invasive imaging techniques and system modeling tools have deepened our insights into the functioning of water and solute transport processes in the soil-plant system. Quantitative approaches that integrate across disciplines and scales constitute stepping stones to foster our understanding of fundamental biophysical processes at the frontier of soil and plants.
This session targets researchers investigating plant-related resource transfer processes across different scales (from the rhizosphere to the global scale) and welcomes scientists from multiple disciplines ranging from soil to plant sciences. We are specifically inviting contributions of:
- Measuring and modeling of water and solute fluxes across soil-plant-atmosphere continuum at different scales.
- Novel experimental and modeling techniques assessing below-ground plant processes such as root growth, root water and nutrient uptake, root exudation, microbial interactions and soil aggregation
- Measuring and modeling of soil-plant hydraulics
- Bridging the knowledge gap between biologically and physically oriented research in soil and plant sciences
- Identification of plant strategies to better access and use resources from soil under abiotic stress
- Mechanistic understanding of drought impact on transpiration and photosynthesis and their predictions by earth system model
Complex interactions between climate, soils and biotic factors are involved in the development of landform-soil-vegetation feedbacks and play an important role in making ecosystems resilient to disturbances. In this context, the importance of soil quality and its functions such as nutrient cycling, carbon sequestration, water quality and biodiversity is more and more recognized for climate regulation and sustainable management of a number of vulnerable landscapes, including wetlands, forests, rangelands and agricultural systems, where the present accelerated changes in climate and land use imposes unprecedent pressures. In addition, large shifts in the distribution of soils and vegetation are associated with losses of ecosystem services, including carbon capture, frequently involving thresholds of landscape stability and nonlinear responses to both human and climatic pressures.
Due to the complex system behavior, it often remains unclear how new management strategies and environmental change influence at different scales the various soil functions and their interactions with coevolving landforms and vegetation. Both computational models and field observations can help to understand and predict the effects of changing environments on these interactions. There is a formidable scientific challenge, however, related to upscaling soil processes and their relevant landform and vegetation interactions for the study of ecosystem functions, from detailed interactions at the pore scale, to effective functions at the soil profile and complex landform-soil-vegetation feedbacks at the landscape scale.
We welcome theoretical, modelling and empirical studies as well as scaling approaches from the pore and soil profile to the landscape scale addressing soil structure and its functions, including carbon and nutrient cycling, the distribution of vegetation and coevolving soils and landforms, and also contributions with a wide appreciation of the soil erosion-vegetation relationships that rule the formation of broad, landscape-level spatial organization. We also welcome studies describing the implications of these spatial patterns for the resilience and stability of ecosystems under the pressure of climate change and/or human disturbances.
We are happy to announce that Bertrand Guenet (CNRS, France) will open the session with a solicited talk on the rationale behind model complexity increase for forecasting soil carbon dynamics in the present context of global changes.

Soil is a vital natural resource acting as a hydrological zone where biological, physical, mechanical and chemical interactions occur. Interactions exist amongst the mineral material of original and deformed rocks, soil life (micro-organisms, plants, animals), climate (water, air, temperature) and human impacts. These interactions occur at different spatial and temporal scales making soil a dynamic, heterogeneous and complex material. In addition, the inherent variability of measured physical, chemical and mechanical parameters shall be taken into account and quantified for geo-material characterization and related hazards. Thus, human activities within urban areas (such as designing of structures and infrastructures, civil protection actions against hazard) and cultivated lands (agricultural and forestry activities) need robust quantitative tools and strategies for soil management. Today, an unprecedented amount of data from various sources is available for geoscientists, engineers and Local Authorities and other parties. A current challenge is to use and interpret such data. Towards this, several informatics’ tools (computational methods; algorithm development; image analysis of 3D/4D imaged data; interactive visualization, mobile apps etc.) have been developed to capture, process, analyze, interpret and deliver soil data to stakeholders.
This session provides an occasion to discuss the best strategy for (1) quantifying and modelling soil complexity and variability and (2) managing soil hazards and resources by exploiting new technologies and informatics tools. In this respect, multidisciplinary contributions related to managing and visualizing large datasets, especially those coming from remote and proximal sensors are appreciated and welcome.

Spatial soil information is fundamental for environmental modelling and land use management. Spatial representation (maps) of separate soil attributes (both laterally and vertically) and of soil-landscape processes are needed at a scale appropriate for environmental management. The challenge is to develop explicit, quantitative, and spatially realistic models of the soil-landscape continuum to be used as input in environmental models, such as hydrological, climate or vegetation productivity (crop models) while addressing the uncertainty in the soil layers and its impact in the environmental modelling. This contemporary research would greatly benefit from synergies between pedometrics and spectroscopy/remote sensing scientists. There is the need to create models linking soil properties with ancillary environmental variables, such as proximal and remote sensing data. Modern advances in soil sensing, geospatial technologies, and spatial statistics are enabling exciting opportunities to efficiently create soil maps that are more consistent, detailed, and accurate than previous maps while providing information about the related uncertainty. The pillars of this paradigm are: a) the link between spectroscopy and wet soil laboratory analysis, seeking for the best strategy to evolve soil quality analysis; b) the link between proximal and remote sensing, with soil analysis; c) the link between proximal/remote sensing and pedometrics for extrapolating relationships established at point support to the spatial and temporal extent covered by proximal/remote sensing. Examples of implementation and use of digital soil maps in different disciplines such as agricultural (e.g. crops, food production) and environmental (e.g. element cycles, water, climate) modelling are welcomed. All presentations related to the tools of digital soil mapping, the philosophy and strategies of digital soil mapping at different scales and for different purposes are welcome.

A transition towards sustainable agriculture is needed to ensure that both present and future societies will be food secure. Current agricultural productivity is already challenged by several factors, such as climate change, availability and accessibility of water and other inputs, socio-economic conditions, and changing and increased demand for agricultural products. Agriculture is also expected to contribute to climate change mitigation, to minimize pollution of the environment, and to preserve biodiversity.
Assessing all these requires studying alternative land management at local to global scales and to assess agricultural production systems rather than individual products.
This session will focus on the modeling of any part of or entire agricultural systems under global change, addressing challenges in adaptation to and mitigation of climate change, sustainable intensification and environmental impacts of agricultural production. We welcome contributions on methods and data, assessments of climate impacts and adaptation options, environmental impacts, GHG mitigation and economic evaluations.

The importance of soil moisture for the hydrological systems dynamics is undebated. A great deal of observations and research have been invested in the last decades to improve the knowledge of soil water status as well its spatial and temporal variation within a given hydrological system. In that effort, several types of soil moisture data have become available, spanning from in-situ observations, radar data, cosmic ray studies to several satellite products.
Although spatial and temporal patterns of soil moisture are the result of processes that hydrological models typically capture, the application of the currently available soil moisture information for improving models is progressing only slowly. This is partly due to a gap between the information content provided by the available data and the information required to improve models. Furthermore, some essential parts of soil water storage at the larger scale, like that of the root zone, is typically assessed using combination of models and data, resulting in a lack of independent information for validation.
This session invites contributions dealing with closing these gaps. This could, for example, be achieved by progress in the descriptions of the processes causing the spatial and temporal variations in soil moisture or by more efficiently using information from available data to improve model predictions across scales. The session is explicitly open for research across all relevant hydrological scales: local, hillslope, catchment up to the continental scale, and deal with both the vertical and lateral flow processes.
Examples for suitable contributions are (but are not limited to):
- The role of soil moisture in the functioning of hydrological systems
- Methods and case studies on improving the predictive power of models using soil moisture data
- Deriving process knowledge from soil moisture data that can be used to improve hydrological models
- Evaluating the suitability of given soil moisture data types for representing hydrologic processes

Agriculture is the largest consumer of water worldwide and at the same time irrigation is one of the sectors where there is one of the hugest differences between modern technology and the largely diffused ancient traditional practices. Improving water use efficiency in agriculture is an immediate requirement of human society for sustaining the global food security, to preserve quality and quantity of water resources and to reduce causes of poverties, migrations and conflicts among states, which depend on trans-boundary river basins. Climate changes and increasing human pressure together with traditional wasteful irrigation practices are enhancing the conflictual problems in water use also in countries traditionally rich in water. Saving irrigation water improving irrigation efficiency on large areas with modern technics is one of the first urgent action to do. It is well known in fact that agriculture uses large volumes of water with low irrigation efficiency, accounting in Europe for around 24% of the total water use, with peak of 80% in the Southern Mediterranean part and may reach the same percentage in Mediterranean non-EU countries (EEA, 2009; Zucaro 2014). North Africa region has the lowest per-capita freshwater resource availability among all Regions of the world (FAO, 2018).
Several recent researches are done on the optimization of irrigation water management to achieve precision farming using remote sensing information and ground data combined with water balance modelling.
In this session, we will focus on: the use of remote sensing data to estimate irrigation volumes and timing; management of irrigation using hydrological modeling combined with satellite data; improving irrigation water use efficiency based on remote sensing vegetation indices, hydrological modeling, satellite soil moisture or land surface temperature data; precision farming with high resolution satellite data or drones; farm and irrigation district irrigation management; improving the performance of irrigation schemes; irrigation water needs estimates from ground and satellite data; ICT tools for real-time irrigation management with remote sensing and ground data coupled with hydrological modelling.

Radionuclide Tracing Technology is a method that uses natural or artificial radionuclides as tracers to reflect the dynamics of soil particle migration and deposition. This method is not restricted by the site, and the measurements of soil erosion is simple and fast. More importantly, it provides the average value of soil erosion rates in a certain period, which can better reflect soil erosion intensity in the study area, and is especially suitable for the areas without any monitoring data. Due to its fast, economical and reliable characteristics, it has been widely used in soil erosion and sediment research in the past few decades. At present, the three tracers of 137Cs, 210Pb and 7Be are most widely used and the application fields have also developed from the soil erosion rate estimation at the scales of site, slope and catchment to sediment deposition study of lakes and reservoirs, the discrimination of sediment source, and the slope erosion process. Accordingly, the applied nuclides for tracing also has evolved from single nuclide, dual ones to composite ones.

The management of soil and water resources for sustainable development is critical for human well-being. Over the recent decades, many studies have demonstrated the role of water and sediment connectivity processes in relation to watershed management. Habitat and species protection, improved flood resistance and resilience, and ecosystems management are all vital to maintaining the health of ecosystems. Especially when external factors influence watershed processes and characteristics to maintain optimal connectivity or disconnectivity in diverse ecological niches (hydrology, ecology, geomorphology) is the goal of watershed management. Given the high complexity of hydro-geomorphic systems and the different mechanisms that might influence the efficiency of water and sediment flowing through a watershed, understanding the hydrological and sediment connectivity is critical. Meanwhile, analyzing changes in connectivity over time helps to understand the effects of natural and man-made disturbances on water-sediment flux and related processes. However, we still have very little understanding about connectivity and link all the processes involved. Models are valid tools in this task, but they need to be improved. In this session, we welcome studies focused on connectivity with watershed management. Any contributions related to new methods, approaches to the understanding of connectivity are welcomed. Field monitoring, laboratory simulations, development and application of geomorphometric indices and models are included. This session emphasizes the importance of connectivity in appropriately managing sediment and water-related concerns, and aims at providing important information on when, where, and how to managers in order to control hydrological and geomorphic processes and ultimately achieve sustainable watershed management.
A well-designed experiment is a crucial methodology in Soil Science, Geomorphology and Hydrology.
Depending on the specific research topic, a great variety of tempo-spatial scales is addressed.
From raindrop impact and single particle detachment to the shaping of landscapes: experiments are designed and conducted to illustrate problems, clarify research questions, develop and test hypotheses, generate data and deepen process understanding.
Every step involved in design, construction, conduction, processing and interpretation of experiments and experimental data might be a challenge on itself, and discussions within the community can be a substantial and fruitful component for both, researchers and teachers.
This PICO session offers a forum for experimentalists, teachers, students and enthusiasts.
We invite you to present your work, your questions, your results and your method, to meet, to discuss, to exchange ideas and to consider old and new approaches.
Join the experimentalists!

Badlands are unique landscapes with intense past or present geomorphological dynamics and high erosion rates, being among the most outstanding and impressive erosion landforms on earth.
Given the problems that follow from the rapidity of geomorphological processes and the high magnitude of erosion of badland areas, there are important associated environmental and management implications (i.e. high sediment transport and water turbidity, loss of biodiversity). Many methods with different degrees of complexity can be used to measure these processes. However, there is not standard protocol for measuring erosion dynamics, and the selection of method mainly depends on several factors as the characteristics of the research group (e.g. number of members, training capacity), financial support (e.g. instrument availability), objectives, and size of the study area. These methods can be mainly considered dynamic or volumetric: (i) dynamic methods aim to measure fluxes from plots (e.g. rainfall simulation, Gerlach troughs), micro-catchments (e.g. collectors), or experimental catchments (e.g. turbidity sensors); while (ii) volumetric methods aim to measure sediment erosion rates through the analysis of topographic changes by sparse observations (e.g. erosion pins, microprofile methods) or by the use of high-resolution topographic survey methods (e.g. Structure from Motion photogrammetry, terrestrial laser scanning). Also, methods should include determining weathering rates of various lithologies in different climate conditions (including both field measurements and simulations in laboratory conditions).
In this session, we would like to gather studies focusing on badland dynamics, especially facing new challenges in measuring geomorphological dynamics and erosion rates: mapping badland evolution and geomorphological dynamics, measuring erosion rates using different methods, discussing new challenges in measuring erosion rates in badlands (including piping erosion), definition of mapping protocol and erosion estimation procedures.
Recent advances in image collection, e.g. using unoccupied aerial vehicles (UAVs), and topographic measurements, e.g. using terrestrial or airborne LiDAR, are providing an unprecedented insight into landscape and process characterization in geosciences. In parallel, historical data including terrestrial, aerial, and satellite photos as well as historical digital elevation models (DEMs), can extend high-resolution time series and offer exciting potential to distinguish anthropogenic from natural causes of environmental change and to reconstruct the long-term evolution of the surface from local to regional scale.
For both historic and contemporary scenarios, the rise of techniques with ‘structure from motion’ (SfM) processing has democratized data processing and offers a new measurement paradigm to geoscientists. Photogrammetric and remote sensing data are now available on spatial scales from millimetres to kilometres and over durations of single events to lasting time series (e.g. from sub-second to decadal-duration time-lapse), allowing the evaluation of event magnitude and frequency interrelationships.
The session welcomes contributions from a broad range of geoscience disciplines such as geomorphology, cryosphere, volcanology, hydrology, bio-geosciences, and geology, addressing methodological and applied studies. Our goal is to create a diversified and interdisciplinary session to explore the potential, limitations, and challenges of topographic and orthoimage datasets for the reconstruction and interpretation of past and present 2D and 3D changes in different environments and processes. We further encourage contributions describing workflows that optimize data acquisition and processing to guarantee acceptable accuracies and to automate data application (e.g. geomorphic feature detection and tracking), and field-based experimental studies using novel multi-instrument and multi-scale methodologies. This session invites contributions on the state of the art and the latest developments in i) modern photogrammetric and topographic measurements, ii) remote sensing techniques as well as applications, iii) time-series processing and analysis, and iv) modelling and data processing tools, for instance, using machine learning approaches.
In a fast-changing environment, earth’s ecosystems are facing multiple stressors compromising the provision of essential services for mankind, and the resiliency of the natural environment itself.
Climate change, water pollution and scarcity affect biodiversity, socio-economic and climate related vulnerabilities and as a consequence, water and food security and human health.
The recent European Green Deal aims at Europe becoming the world’s first climate-neutral continent by 2050 and it does so by setting climate, energy, transport and taxation policies fit for reducing net greenhouse gas emissions by at least 55% by 2030. This program sets ambitious yet realistic targets for the next decades, auspicating the transformation of European Countries into a modern resource-efficient economy and society in line with the Sustainable Development Goals.
However, to address both the impacts as well as the causes of climate change, it is fundamental to create conditions where ecosystem services are optimized for both the local population and global objectives. Yet, the use of ecosystem services assessment in decision making might prove challenging when it comes to economic and social domains, as well as the perception and concept of natural environment may differ across disciplines. Such transdisciplinary approach plays a key role in Nature Based Solutions and opens up to the participation of multiple stakeholders in local governance, thus offering a multitude of co-benefits for the environment and for communities.
This session aims at opening a common ground between the natural, physical, social and economic sciences towards a resilient planet, by providing examples of challenges and opportunities and harmonizing best practices in this field.
We welcome transdisciplinary contributions on terrestrial, marine, and urban ecosystem services assessment that take into account the natural and the human dimension, advance in modelling complex spatio-temporal and social dynamics and transdisciplinary approaches towards nature inspired and supported solutions for social benefits and ecosystems’ resilience.

Nature-Based Solutions and Climate Engineering in Climate Governance
As reaching the Paris agreement goal of limiting the global mean surface warming even below 2ºC becomes increasingly difficult with only emission reduction, additional measures complementing greenhouse gas (GHG) emission reductions to limit global warming gain more attention: Nature-based Solutions and Climate Engineering.
Nature-based solutions (NbS) have gained popularity as a set of integrated approaches that contribute to climate change adaptation, slowing further global warming, supporting ecosystem services and biodiversity, while promoting sustainable development. To achieve the full potential of NbS to address climate change, there is an urgent need for multidisciplinary teams of scientists to articulate solutions that engage policy makers and enable NbS interventions to reduce carbon emissions while benefiting human well-being. This will require systemic change in the way we conduct research, promote collaboration between institutions and with policy makers.
Climate Engineering (CE) is much more controversial. Carbon Dioxide Removal (CDR) aims at removing CO2 from the atmosphere through techniques such as ocean fertilization, artificial upwelling or enhanced weathering. CE has been criticized for creating potentially dangerous side effects, distracting from the root cause of climate change (GHG emissions), and being difficult to govern. So what, if any, should be the future role of CDR and SRM in the climate governance toolbox and to what extent should CE research have high priority? which knowledge gaps must be addressed before a decision for or against these techniques can be taken?
This session aims to advance knowledge of innovative NbS approaches for more inclusive and resilient communities from inter-disciplinary perspectives.
Specific topics include, but are not limited to:
— Benefits: The potential of NbS and CE to help achieving climate goals
— Feasibility: Tools and best practices enabling successful implementation and upscaling of NbS; impact assessment of real-life NbS projects, especially for the Global South and developing countries; and technical feasibility and risks in implementing CE
— Viability: Cost-benefit analysis of NbS and CE to multiple Sustainable Development Goals
— Governance: New NBS governance models and co-creation approaches and tools; and regional and global challenges and solutions for fair and inclusive governance of CE.

Meet editors of internationally renowned journals in geo- and biogeoscience and gain exclusive insights into the publishing process. After a short introduction into some basics, we will start exploring various facets of academic publishing with short talks given by the editors on
- What are the duties and roles of editors, authors and reviewers?
- How to choose a suitable journal for your manuscript and what is important for early career authors?
- How can early career scientists get involved in successful peer-reviewing?
- What is important for appropriate peer-reviewing?
- What are ethical aspects and responsibilities of publishing?
Together with the audience and the editors, we will have an open discussion of the key steps and factors shaping the publication process of a manuscript. This short course aims to provide early career scientists across several EGU divisions (e.g. AS, BG, CL, GM, NH, SSP and SSS) the opportunity of using first hand answers of experienced editors of international journals to successfully publish their manuscripts and get aware of the potentials and pitfalls in academic publishing.

Sexual and racial harassment and other hostile behaviors, including bullying and other forms of discrimination and incivilities, have wide-ranging detrimental effects on mental and physical wellbeing, including anxiety, depression, and physiological responses akin to trauma, and can result in decreased motivation and work productivity. The tolerance of hostile behaviors can affect the community beyond the individual or individuals being targeted, and create negative work environments in entire research groups and departments. Traditional hierarchical structures within academia that create strong power imbalances allow for the potential for abuse in research and educational environments. Despite this, scientists often do not receive mentoring or training in how to address, respond to, and prevent these types of behaviors. Questions including “What behaviors are appropriate at work?”, “How do we create a work environment where people of different age, gender and sexual identity, culture, religion, ethnic origin and social class feel respected and included?” and “What can I do personally against bullying and sexual harassment at work?” are important topics that are not discussed enough in academia. Promoting conversations about these topics and identifying ways to prevent unwanted behavior are important steps towards building respectful and productive work environments.
This interactive short course explores academic practices and institutional structures that allow for harassment and other hostile behaviors to persist, discusses initiatives to address harassment as scientific misconduct, and provides training in personal intervention strategies to protect and support targets of harassment through real world scenarios. As a result of this session, participants will be able to identify:
(1) Different ways in which harassment can manifest in research environments;
(2) Strategies for bystander intervention, and
(3) Resources for cultural change in the office, laboratory, at conferences and in field settings.
This workshop was developed by ADVANCEGeo (serc.carleton.edu/advancegeo) with a U.S. National Science Foundation ADVANCE Partnership award in collaboration with the Earth Science Women's Network, the Association for Women Geoscientists and the American Geophysical Union. We welcome participants from a diverse background of Geosciences, career stages and countries.
Science is a key component of the policymaking process as it allows decision-makers to consider the evidence and potential consequences of any action or inaction. The growing complexity of societal challenges, and the policies needed to deal with them, also means that more frequent and consistent interactions between scientists and policymakers is needed.
While individual scientists can (and definitely should) engage in formal and informal policymaking processes, it’s often more effective and efficient for institutions to communicate scientific information and to be available for follow-up questions when needed. Furthermore, by engaging with the policymaking process, institutions are both supporting evidence-informed decision-making and promoting the research of their scientists and potentially increasing its impact.
Knowing exactly when or how to engage with policymaking as a scientific institution can, however, be extremely challenging. It can be daunting for a scientific organisation of any size to select a policy area to focus on, gather enough information to understand who the relevant stakeholders are, and know what information is most relevant and how to best communicate it!
This Short Course will feature the European Commission Joint Research Centre's recently launched Science for Policy Competence Framework for researchers. This Framework outlines the different competencies that research organisations need to effectively contribute to the science-policy interface. It unpacks the collective set of skills, knowledge, and attitudes desired at four different proficiency levels. It’s hoped that organisations can use this framework to see where their strengths and skill gaps are!
The “Theory and simulation of solar system plasmas” session is a long-standing element of the EGU programme, covering all aspects of theoretical modelling and computer simulation of plasmas in the heliosphere, interfacing with observations, relating to the Sun and its atmosphere, the solar wind, planetary magnetospheres and interplanetary space. This provides a forum to present advances in plasma theory relevant to current and future space missions, such as MMS, Parker Solar Probe and Solar Orbiter, as well as space exploration including space stations, the moon and Mars. Each year, a topic of special focus is chosen, and for 2022 this will be “Integration of fluid and kinetic models of solar system plasmas”. One of the major challenges facing modellers is the vast range of temporal and spatial scales that must be encompassed, from the smallest kinetic scales such as electron gyro-radii, to the largest global scales which can be treated by fluid models. Furthermore, the strong variation in parameters between different parts of the heliosphere must be accounted for in integrated models. Therefore, this year we particularly encourage presentations on approaches to tackle these challenges, including new codes and methodologies, and their application to heliospheric plasma processes such as waves, turbulence and magnetic reconnection - and interfaces with observations from current space missions, and planning of future missions.

Presentations will cover various approaches for tackling these challenges, including new codes and methodologies, and their application to heliospheric plasma processes such as waves, turbulence and magnetic reconnection - and interfaces with observations from current space missions, and planning of future missions.
This session focuses on the non-linear processes that take place in space, laboratory and astrophysical plasma. These processes are usually not separated from one another and often go "hand in hand". Just to mention a few examples, magnetic reconnection is an established ingredient of the turbulence cascade and it is also responsible for the production of turbulence in reconnection outflows; shocks may form in collisional and collisionless reconnection processes and can be responsible for turbulence formation, as for instance in the turbulent magnetosheath; magnetic and velocity-shear driven instabilities triggers plasma turbulence in their non-linear phase and can locally develop in turbulent plasmas. All these non-linear processes are responsible for particle acceleration and plasma heating in the environments where they take place.
We are now in a fortunate time for the investigation of these processes, where we can use a combined approach based on simulations and observations together. Simulations can deliver output in a temporal and spatial range of scales going from fluid to electron kinetic. On the observation side, high cadence measurements of particles and fields, high resolution 3D measurements of particle distribution functions and multipoint measurements make it easier to reconstruct the 3D space surrounding the spacecrafts. In this context, the Parker Solar Probe and the Solar Orbiter mission are opening new research scenarios in heliophysics, providing a consistent amount of new data to be analysed.
This session welcomes simulations, observational, and theoretical works relevant for the study of the above mentioned plasma processes. Particularly welcome this year, will be works focusing on how non-linear processes accelerate particles and produce heating in collisionless plasmas. We also encourage papers proposing new methods in simulation techniques and data analysis, as for example those rooted in Artificial Intelligence and Machine Learning.

Cosmic rays carry information about space and solar activity, and, once near the Earth, they produce isotopes, influence genetic information, and are extraordinarily sensitive to water. Given the vast spectrum of interactions of cosmic rays with matter in different parts of the Earth and other planets, cosmic-ray research ranges from studies of the solar system to the history of the Earth, and from health and security issues to hydrology and climate change.
Although research on cosmic-ray particles is connected to a variety of disciplines and applications, they all share similar questions and problems regarding the physics of detection, modeling, and the influence of environmental factors.
The session brings together scientists from all fields of research that are related to monitoring and modeling of cosmogenic radiation. It will allow sharing of expertise amongst international researchers as well as showcase recent advancements in their field. The session aims to stimulate discussions about how individual disciplines can share their knowledge and benefit from each other.
We solicit contributions related but not limited to:
- Health, security, and radiation protection: cosmic-ray dosimetry on Earth and its dependence on environmental and atmospheric factors
- Planetary space science: satellite and ground-based neutron and gamma-ray sensors to detect water and soil constituents
- Neutron and Muon monitors: detection of high-energy cosmic-ray variations and its dependence on local, atmospheric, and magnetospheric factors
- Hydrology and climate change: low-energy neutron sensing to measure water in reservoirs at and near the land surface, such as soils, snow pack, and vegetation
- Cosmogenic nuclides: as tracers of atmospheric circulation and mixing; as a tool in archaeology or glaciology for dating of ice and measuring ablation rates; and as a tool for surface exposure dating and measuring rates of surficial geological processes
- Detector design: technological advancements for the detection of cosmic rays
- Cosmic-ray modeling: advances in modeling of the cosmic-ray propagation through the magnetosphere and atmosphere, and their response to the Earth's surface
- Impact modeling: How can cosmic-ray monitoring support environmental models, weather and climate forecasting, irrigation management, and the assessment of natural hazards

The increasing amount of data from an increasing number of spacecraft in our solar system shouts out for new data analysis strategies. There is a need for frameworks that can rapidly and intelligently extract information from these data sets in a manner useful for scientific analysis. The community is starting to respond to this need. Machine learning, with all of its different facets, provides a viable playground for tackling a wide range of research questions in planetary and heliospheric physics.
We encourage submissions dealing with machine learning approaches of all levels in planetary sciences and heliophysics. The aim of this session is to provide an overview of the current efforts to integrate machine learning technologies into data driven space research, to highlight state-of-the art developments and to generate a wider discussion on further possible applications of machine learning.

The Sun’s corona is the birthplace of the solar wind, coronal mass ejections, associated shock waves, and solar energetic particles which all are fundamental drivers of space weather. The key physical processes at the origin of these phenomena, i.e., the heating and acceleration of the coronal plasma and energetic particles, are not completely understood to date. During EGU 2022, Parker Solar Probe (PSP) would have completed 11 of its 24 scheduled orbits around the Sun. During orbits 10 and 11, the spacecraft will go as close as 13.3 solar radii from the Sun’s center. PSP has already provided a treasure trove worth of in-situ and remote sensing data that have revealed phenomena never seen before in terms of generation of solar wind turbulence, fine-structures of coronal mass ejections, solar energetic particle flows, traces of dust particles and even in planetary physics on Venus. The formal commissioning phase of Solar Orbiter (SolO) ended in mid-June 2020 and valuable data has been provided during the cruise phase of the mission, primarily by the in-situ instruments. The nominal phase of the mission will start at the end of 2021. Combining the PSP and SolO observations with observations from other space-born missions and ground-based observatories (e.g., SDO, STEREO, Proba2, ACE, WIND, DSCOVR, and DKIST ), and with theoretical models is a challenging and exciting task. This session invites scientific contributions on all aspects of research addressed to the exploration of our near-Sun environment, with special focus on the new observations from PSP and SolO and other complementary observations and models.

Since the late 1950’s the neutron monitor (NM) network provides continuous measurements of the cosmic ray (CR) environment, shading light upon the physical mechanisms of solar relativistic ion acceleration, injection and propagation during Ground Level Enhancements (GLEs), as well as the effect of large scale structures (i.e. interplanetary coronal mass ejections – ICMEs and corotating interaction regions – CIRs) propagating in the solar wind resulting in short-term decreases of galactic cosmic rays (GCRs), termed as Forbush decreases (FDs) and the long-term behavior of CRs. Since 2008, the majority of NMs provide data through a single repository, the Neutron Monitor Database (NMDB), making it straightforward for the scientific community to retrieve such data. The NM network has paved the way for the understanding of the near-Earth and the inner heliosphere radiation environment and corroborates with the findings of spacecraft missions, specifically recent measurements of high energy particles from PAMELA, AMS onboard the International Space Station and EPHIN onboard SOHO. At the same time, the network of NMs is extensively used for the establishment of space-weather related services, such as alerts of GLEs and estimations of the radiation environment within the atmosphere, the magnetosphere and beyond. Also, new detectors and electronics expand the current NM network whereas algorithms for the treatment of the data are being investigated.
With a view to the future, the NM network faces challenges with respect to its sustainability, evolution, continuous and updated usage by the scientific community. Nonetheless, the future perspectives of the network are promising, with the NM data being used in a large variety of fields – even non-conventional ones. This session brings together scientists from research fields related to space, solar, neutron monitor, heliospheric and atmospheric sciences. The session solicits contributions related but not limited to:
• Modeling of GLEs, short term FDs and GCRs modulation;
• Long-term variability of the CR flux from ground based and spacecraft measurements;
• Evaluation and quantification of the radiation environment in the inner heliosphere and the Earth’s atmosphere;
• Space-weather services based on the NM network;
• Influence of solar activity and the effect of cosmic rays on the atmosphere;
• Instrumentation, algorithms and data access for ground-based CR detectors.
The Interstellar Boundary Explorer (IBEX) Mission, launched in 2008, in concert with in situ measurements by the Voyager spacecraft have initiated a remarkable scientific quest to discover the global heliosphere and its interaction with the local galactic environment through which our Sun and solar system move. The global boundaries that surround our solar system and the IBEX ribbon are created through a myriad of complex physical processes that mediate the interactions between the solar wind, the local interstellar flow, and the local interstellar magnetic field. At this point in time, more than a solar cycle of IBEX data has been accrued, revealing not only the global properties of our heliosphere, but also our first views of their variations in time. The rich science of the global heliosphere, our growing understanding of suprathermal particle populations that influence interstellar interactions, and expanded research into the properties of the local interstellar medium have helped to usher in the next steps of exploration to be taken by the upcoming Interstellar Mapping and Acceleration Probe (IMAP), due to launch in 2025. This session is devoted to the science that is advancing our quest to discover the complex physics of our global heliosphere and its interaction with the local interstellar medium.

Space and astrophysical plasmas are typically in a turbulent state, exhibiting strong fluctuations of various quantities over a broad range of scales. These fluctuations are non-linearly coupled and this coupling may lead to a transfer of energy (and other quantities such as cross helicity, magnetic helicity) from large to small scales and to dissipation. Turbulent processes are relevant for the heating of the solar wind and the corona, acceleration of energetic particles. Many aspects of the turbulence are not well understood, in particular, the injection and onset of the cascade, the cascade itself, the dissipation mechanisms, as well as the role of specific phenomena such as the magnetic reconnections, shock waves, expansion, and plasma instabilities and their relationship with the turbulent cascade and dissipation.
This session will address these questions through discussion of observational, theoretical, numerical, and laboratory work to understand these processes. This session is relevant to many currently operating missions (e.g., Wind, Cluster, MMS, STEREO, THEMIS, Van Allen Probes, DSCOVR) and in particular for the Solar Orbiter and the Parker Solar Probe.

Coronal mass ejections (CMEs), in addition to corotating density structures and solar energetic particles (SEPs), are known to be the driving force behind significant space weather disturbances at Earth and other planets. Understanding their physical behaviour and making accurate predictions about their arrival times and properties is a difficult and ongoing issue in heliophysics. Remote-sensing and in-situ measurements from multiple vantage points, combined with ground-based observations and modelling efforts, are employed to study the solar wind plasma and CMEs from their onset to their arrival at planets and spacecraft throughout the heliosphere.
Recently launched spacecraft including Parker Solar Probe, Solar Orbiter, BepiColombo, in addition to existing missions such as STEREO and future missions to L1 and L5 present an ideal opportunity to test, validate and refine current knowledge in this field. We therefore encourage submissions with the aim of exploiting the latest observational and modelling efforts regarding CME and solar wind evolution during their propagation throughout the heliosphere.

The heliosphere is permeated with energetic particles of different compositions, energy spectra and origins. Two major populations of these particles are galactic cosmic rays (GCRs), which originate from outside of the heliosphere and are constantly detected at Earth, and solar energetic particles (SEPs) which are accelerated at/near the Sun during solar flares or by shock fronts associated with the transit of coronal mass ejections. Enhancements in energetic particle fluxes at Earth pose a hazard to humans and technology in space and at high altitudes. Within the magnetosphere, energetic particles are present in the radiation belts, and particle precipitation is responsible for the aurora and for hazards to satellites. Energetic particles have also been shown to cause changes is the chemistry of the middle and upper atmosphere, thermodynamic effects in the upper troposphere and lower stratosphere region, and can influence components of the global electric circuit. This session will aim to address the transport of energetic particles through the heliosphere, their detection at Earth and the effects they have on the terrestrial atmosphere when they arrive. It will bring together scientists from several fields of research in what is now very much an interdisciplinary area. The session will allow sharing of expertise amongst international researchers as well as showcase the recent advances being made in this field, which demonstrate the importance of the study of these energetic particle populations.

Turbulence and magnetic reconnection are multiscale processes that convert energy from outer to inner scales. In the last decades, the improvement of observational and computational capabilities has suggested close links between turbulence and reconnection in Heliospheric and magnetospheric plasmas. Thanks to high-cadence and multi-spacecraft measurements, as well as large-scale computations, it has become possible to study the interplay between these fundamental processes across a broad range of scales, including electron-scales. This session welcomes contributions from observational, numerical and theoretical work, including new techniques and methods for characterising the links between reconnection and turbulence. Topics of interest include reconnection that occurs in turbulent systems, turbulence generated by reconnection events, the role of reconnection in the development of kinetic turbulence, and the influence of turbulence and reconnection on energy dissipation.

The session solicits contributions that report on nonthermal solar and planetary radio emissions. Coordinated multi-point observations from ground radio telescopes (e.g., LOFAR, LOIS, LWA1, URAN-2, UTR-2) and spacecraft plasma/wave experiments (e.g., Cassini, Cluster, Demeter, Galileo, Juno, Stereo, Ulysses and Wind) are especially encouraged. Presentations should focus on radiophysics techniques used and developed to investigate the remote magnetic field and the electron density in solar system regions, like the solar corona, the interplanetary medium and the magnetized auroral regions. Interest also extends to laboratory and experimental studies devoted to the comprehension of the generation mechanisms (e.g., cyclotron maser instability) and the acceleration processes (e.g., Alfven waves). Further preparations, evaluations, investigations, analyses of forthcoming space missions or nanosatellites (like BepiColombo, Juice, Solar Orbiter, Solar Probe, SunRISE, UVSQ-Sat, Inspire-Sat 7) are also welcome.

Observations and measurements of geophysical systems and dynamical phenomena are obtained as time series or spatio-temporal data whose dynamics usually manifests a nonlinear multiscale (in terms of time and space) behavior. During the past decades, nonlinear approaches in geosciences have rapidly developed to gain novel insights on weather and climate dynamics, fluid dynamics, on turbulence and stochastic behaviors, on the development of chaos in dynamical systems, and on concepts of networks, nowadays frequently employed in geosciences.
In this short course, we will offer a broad overview of the development and application of nonlinear concepts across the geosciences in terms of recent successful applications from various fields, ranging from climate to near-Earth space physics. The focus will be on a comparison between different methods to investigate various aspects of both known and unknown physical processes, moving from past accomplishments to future challenges.

The session covers contributions on dwarf planets and small solar system objects, including comets, asteroids, meteoroids, and dust. Topics include dynamics, evolution, physical properties, and interactions of dust and meteors in space as well as planetary atmospheres. Presenters are invited to highlight results obtained from recent space missions (SO, PSP, etc.), observations, laboratory studies, theoretical and numerical simulations, as well as the latest results on the physics of meteors and of dust in ionospheres, ionospheric phenomena, other atmospheric phenomena, and space weathering of surfaces.

This open session traditionally invites presentations on all aspects of the Earth’s magnetospheric physics, including the magnetosphere and its boundary layers, magnetosheath, bow shock and foreshock as well as solar wind-magnetosphere-ionosphere coupling. We welcome contributions on various aspects of magnetospheric observations, remote sensing of the magnetosphere’s processes, modelling and theoretical research. The presentations related to the current and planned space missions and to the value-added data services are also encouraged. This session is suitable for any contribution which does not fit more naturally into one of the specialised sessions and for contributions of wide community interest.

Wave-particle interactions represent a unique mechanism of an energy transfer in the nearly collisionless plasma environment of the Earth's inner magnetosphere, affecting ultimately distribution functions of energetic particles trapped in the Van Allen radiation belts. Their evaluation, along with the quantification of the resulting particle acceleration, transport, and loss, is thus crucial for understanding the dynamics of the radiation belts. Considering that these processes are mainly driven by the solar wind, the ability to accurately forecast the radiation belts is further dependent on understanding their coupling with external regions (e.g. solar wind, foreshock, magnetosheath), and the processes that dictate their global dynamics. Additionally, precipitating magnetospheric particles cause changes in the ionospheric conductivity and may affect the upper atmospheric chemistry. The aim of this session is to discuss the dynamics of energetic particle populations in the radiation belts, wave-particle interactions in the Earth's inner magnetosphere, as well as generation mechanisms and properties of involved electromagnetic emissions (EMIC, chorus, hiss, fast magnetosonic waves, etc.) in various frequency ranges (ULF, ELF, VLF). Theoretical and model contributions, as well as observational studies using data from older and recent satellite missions (Cluster, MMS, THEMIS, Van Allen Probes, ERG-Arase, etc.) and ground-based instruments are encouraged.
Positive solar wind pressure pulses are pockets of solar wind plasma that are faster and/or denser than the surrounding ambient plasma. When a pressure pulse impacts the terrestrial magnetosphere, it is rapidly compressed, and the effects propagate inwards resulting in a well observed enhancement in the magnetic field, as evidenced in the SYM-H index; this communication of a pressure pulse into the magnetosphere is known as a geomagnetic sudden commencement (SC). SCs can be further subdivided into sudden impulses (SIs) and sudden storm commencements (SSCs), where in the latter case, the pressure pulse triggers a geomagnetic storm. Even for small, short lived, pressure enhancements, the effects on the terrestrial magnetosphere can be dramatic, exciting and even reconfiguring the electrodynamics within. Among these effects, observations and modelling have shown: enhancements and restructuring of high latitude ionospheric currents and convection; auroral emission excited by particle precipitation; energisation of the plasmasphere; excitation of magnetospheric current systems; enhanced ULF wave activity.
In this session, we invite contributions based on both observations and modelling of the effect of solar wind pressure pulses on the coupled solar wind – magnetosphere – ionosphere system. We seek to facilitate crossover discussion between the observational and modelling communities on pressure pulse driving of phenomena including (but not limited to): ULF wave propagation; ionospheric convection; ionospheric and magnetospheric current systems; auroral emission; terrestrial radio emissions; plasmasphere effects.

Large-scale dynamic processes in different magnetospheric regions, e.g., at the magnetopause, in the dayside magnetosphere, magnetotail, ring current, plasmasphere, ionosphere, are generally interconnected therefore the magnetosphere should be considered as a global system. The state of the magnetosphere is controlled mainly by solar wind conditions. The interplanetary magnetic field (IMF) and solar wind plasma parameters regulate the energy input into the magnetosphere. Magnetic reconnection at the dayside magnetopause and in the tail current layer regulate energy transfer through the magnetosphere. Changes in the solar wind dynamic pressure and IMF move the magnetopause, causing global magnetospheric expansions and contractions. Variations in the solar wind velocity and IMF direction may also displace the magnetotail. Processes within the magnetotail inject thermal and energetic particles into the inner magnetosphere and downward along magnetic field lines into the ionosphere. On the other hand, the polar wind from the upper atmosphere may influence nightside reconnection rates. Global magnetospheric dynamics can be studied by means of numerical simulations (MHD or kinetic), using empirical and semi-empirical models, or with the help of multipoint in situ spacecraft observations. Arrays of ground-based observatories and individual well-situated space missions can image magnetospheric and ionospheric phenomena globally, providing crucial information concerning the positions and dynamics of the magnetospheric plasma boundaries and the global distribution of ionospheric currents, convective flows, and particle precipitation. Accurate modelling of global magnetospheric processes is an essential condition for successful space weather predictions. We welcome any work presenting results on the global dynamics of the Earth’s magnetosphere as well the magnetospheres of other planets and for instance modeling activities undertaken for the preparation of the future Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) mission.
The Earth's inner magnetosphere contains different charged particle populations, such as the Van Allen radiation belts, ring current particles, and plasmaspheric particles. Their energy range varies from eV to several MeV, and the interplay among the charged particles provides feedback mechanisms that couple all those populations together. Ring current particles can generate various waves, for example, EMIC waves and chorus waves, which play important roles in the dynamic evolution of the radiation belts through wave-particle interactions. Ring current electrons can be accelerated to relativistic radiation belt electrons. The plasmaspheric medium can also affect these processes. In addition, precipitation of ring current and radiation belt particles will influence the ionosphere, while up-flows of ionospheric particles can affect dynamics in the inner magnetosphere. Understanding these coupling processes is crucial.
While the dynamics of outer planets’ magnetospheres are driven by a unique combination of internal coupling processes, these systems have several fascinating similarities which make comparative studies particularly interesting. We invite a broad range of theoretical, modeling, and observational studies focusing on the dynamics of the inner magnetosphere of the Earth and outer planets, including the coupling of the inner magnetosphere and ionosphere and coupling between the solar wind disturbances and various magnetospheric processes. Contributions from all relevant fields, including theoretical studies, numerical modeling, observations from satellite and ground-based missions are welcome. In particular, we encourage presentations using data from MMS, THEMIS, Van Allen Probes, Arase (ERG), Cluster, cube-sat missions, Juno, SuperDARN, magnetometer, optical imagers, IS-radars, and ground-based VLF measurements.
Geomagnetically Induced Currents (GICs) can damage grounded infrastructure such as high voltage transformers, gas pipelines and rail networks. Understanding their impact is vital for protecting critical national infrastructure from harm and reducing any economic consequences. GICs are caused by geoelectric fields induced in the resistive subsurface during periods of rapid change of the magnetic field, typically in geomagnetic storms; however, an increasing body of evidence shows they occur in nominally quiet times too. We seek contributions from studies that measure (directly or indirectly) or model GICs in grounded infrastructure to assess the potential hazard and vulnerability of the infrastructure and to produce reliable models with which to forecast the potential effects of severe space weather events.

In his seminal work "Weather Prediction by Numerical Process" in 1922, Lewis Fry Richardson proposed his famous cascade picture qualitatively, for a turbulent flow where the energy is transferred from large scale structures to small scale ones, until reaching viscosity scales where it is converted to heat. This picture now has been widely adopted to describe different type of turbulent phenomena, for not only the classical hydrodynamic turbulence, but also, not limited to, the movement of atmosphere and oceans.
After 100 years of developments, the concept of cascades has been extended significantly. Now, it describes mainly the nonlinear interactions crossing a large range of scales where scale invariants might emerge spontaneously. More precisely, balances between the external forcing and the dissipation are expected for a turbulent system. However, due to the complexity of atmospheric or oceanic systems, such as earth rotation, stratification, large aspect ratio, mesoscale eddies, ocean current, tidal, waves, etc., the exact balance is still unknown. We still lack an efficient methodology to diagnose the scale-to-scale energy or other physical quantities fluxes to characterize the cascade quantitatively, e.g., strength, direction, etc.
With the increasing capability of remote sensing, computational fluid dynamics, field observation, etc., we have accumulated a large amount of field data. It is now a suitable time to celebrate the 100th Anniversary of Richardson's idea of cascades in the geosciences, and to understand it quantitatively.
This interdisciplinary session welcomes theoretical, methodological, laboratory, data analysis works that aim to characterize the cascade in atmosphere and oceans and other fields.

Plasma density irregularities can occur at all latitudes in the Earth’s ionosphere. However, the onset and evolution of these irregularities as well as their influence on the radio wave signals continue to be unsolved scientific questions. The various proposed generation mechanisms, including instability growth rates and seeding processes, are strongly coupled to the neutral atmosphere and magnetospheric dynamics, making the forecasting of ionospheric irregularities much more challenging. Recent observations from ground- and space-based measurements, as well as new innovative data analysis and modeling techniques, e.g., data assimilation and machine learning, have the potential to advance our understanding of the ionospheric irregularities. Studies that focus on the observation, modeling and prediction of plasma irregularities of different scales are welcome at this session. The mitigation of negative effects and recent developments to forecast scintillation effects on Global Navigation Satellite or other communication systems are also of high interest.
The Earth's ionosphere embedded in the thermosphere is a coupled system influenced by solar and magnetospheric processes from above, as well as by upward propagating disturbances from lower atmospheric layers. This open session is suitable for contributions on all aspects of ionospheric and thermospheric physics and ionospheric effects on HF propagation. The session invites theoretical studies, (multi)instrumental ground-based and satellite observations, simulations and modelling studies that address the dynamics of the ionosphere, concerning transient events, plasma waves and irregularities, as well as large-scale dynamics and long-term variations. Contributions dealing with magnetospheric forcing are sought in the areas of ionospheric disturbances caused by CME- and CIR/CH HSS-related magnetic storms and substorms. New results that focus on investigation of latitudinal, seasonal and hemispherical effects of the storms and substorms on ionosphere are especially appreciated. Also ionospheric effects from other sources, such as solar terminator, solar eclipse, seismic activity or human-made explosions, are welcome. As for lower atmosphere forcing, contributions are sought that focus on atmospheric waves, wave-wave and wave-mean flow interactions, atmospheric electricity and electrodynamical coupling processes.

Solar wind energy enters the Earth's high latitude region through magnetic reconnection. Due to the different response time of Region 1 and Region 2 field-aligned currents to changes in magnetospheric convection, the high latitude electric field can penetrate into middle and low latitudes. The Joule heating in the polar region enhances the neutral temperature which alters atmospheric circulation and causes temporal and spatial changes of the ionosphere and thermosphere density and composition at middle and low latitudes. Furthermore, the inner magnetospheric electric field is projected to the ionospheric subauroral region along the geomagnetic field, driving fast plasma flows and associated wind jets. This subauroral electric field can also penetrate down to the equatorial region, and the ion-neutral frictional heating in the subauroral region leads to large variations in neutral temperature and pressure gradients, which result in global neutral wind circulation and composition variations. All these processes can cause drastic changes in the ionosphere and thermosphere both at middle latitudes and in the equatorial region during geomagentically active periods. This session aims to solicit presentations of new research progresses in the dynamic, eletrodynamic and chemical coupling across different latitudes. Both simulation and observation works are welcome.

The upper and middle atmosphere is subject to a combination of dynamics,
e.g., fluid-dynamic, chemical, and electrodynamical processes. These
processes drive vertical interactions among different atmospheric regions on
a broad range of spatial and temporal scales through various mechanisms,
including atmospheric circulation and waves (e.g., planetary waves, tides,
gravity waves), recurring patterns (the El Niño–southern oscillation and the
quasi-biennial oscillation), transient phenomena (e.g., sudden stratospheric
warming), and long-term trends. The current session aims to emphasize the
recent contributions on vertical coupling within the atmosphere-ionosphere
system. We invite relevant papers on methodologies, theory, modeling,
experiment, and observations of different aspects.

The ionospheres and (induced) magnetospheres of unmagnetized and weakly magnetized bodies with substantial atmospheres (e.g. Mars, Venus, Titan, Pluto and comets) are subject to disturbances due to solar activity, interplanetary conditions (e.g. solar flares, coronal mass ejections and solar energetic particles), or for moons, parent magnetospheric activity. These objects interact similarly as their magnetized counterparts but with scientifically important differences.
As an integral part of planetary atmospheres, ionospheres are tightly coupled with the neutral atmosphere, exosphere and surrounding plasma environment, possessing rich compositional, density, and temperature structures. The interaction among neutral and charged components affects atmospheric loss, neutral winds, photochemistry, and energy balance within ionospheres.
This session invites abstracts concerning remote and in-situ data analysis, modelling studies, comparative studies, instrumentation and mission concepts for unmagnetized and weakly magnetized solar system bodies.

Coronal Mass Ejections and their interplanetary counterparts (ICMEs), the associated shocks, the high-speed streams of solar wind from corotating interaction regions (CIRs), and the solar energetic particles (SEPs) are the main drivers of the heliospheric variability. The corresponding geospace disturbances affect a wide range of technological systems in space and on ground, as well as human health. Therefore, the prediction of their arrival and impact is extremely important for the modern space-exploration and electronics-dependent society.
Significant efforts have been made in the past decade to develop and improve the prediction capabilities, through both state-of-the art observations and modelling. Although significant progress has been made, many new challenges have been revealed. We are limited in obtaining reliable observation-based input for the models, tracking solar wind transients throughout the heliosphere and reliably evaluating prediction models. These challenges can be tackled by exploiting and improving our existing capabilities, as well as using the out-of-the-box thinking and break from the traditional methods.
This session is devoted to provide the overview of the current state of the space weather prediction of the arrival time and impact of various solar wind transients and to introduce new and promising observational and modelling capabilities.
We solicit abstracts on observational and modelling efforts, as well as space weather prediction evaluation. With the overview of our current capabilities and possible future prospects we aim to highlight guidelines to the general direction of the future scientific efforts, as well as space-mission planning.

Space Weather (SW) and Space Climate (SC) are collective terms that describe the Sun-Earth system interactions on timescales varying between minutes and decades and include processes at the Sun, in the heliosphere, magnetosphere, ionosphere, thermosphere and at the lower atmosphere. Being able to predict (forecast and nowcast) the extreme events and develop the strategy for mitigation vital as the space assets and critical infrastructures, such as communication and navigation systems, power grids, and aviation, are all extremely sensitive to the external environment. Post-event analysis is crucially important for the development and maintenance of numerical models, which can predict extreme SW events to avoid failure of the critical infrastructures.
This session aims to address both the current state of the art of SW products and new ideas and developments that can enhance the understanding of SW and SC and their impact on critical infrastructure. We invite presentations on various SW and SC-related activities in the Sun-Earth system: forecast and nowcast products and services; satellite observations; model development, validation, and verification; data assimilation; development and production of geomagnetic and ionospheric indices. Talks on SW effects on applications (e.g. on airlines, pipelines and power grids, space flights, auroral tourism, etc.) in the Earth’s environment are also welcomed.
It is well known that solar activity influences the state of the circumterrestrial space and can affect technological systems in many different ways and with different degrees of damage severity.
Geomagnetic data, both from ground-based observatories and low Earth orbit satellites, represent a powerful tool to monitor space weather events, such as magnetic storms, substorms and geomagnetically induced currents.
Geomagnetic field monitoring makes it possible to improve internal geomagnetic field models and gain better knowledge on the dynamics of solar-terrestrial events and ionospheric and magnetospheric geomagnetic sources (both internal and external). Furthermore, geomagnetic field data provide proxies to nowcast and forecast different ground effects due to space weather events.
In this session we therefore encourage submissions focussing on the use of geomagnetic data (from ground observatories to satellites such as CHAMP, Swarm, CSES, ePOP and others) as a tool to gain insight both into the physics of the processes involving the Earth's magnetic field in response to space weather events and into their effects as the degradation of satellite signal, perturbation in radio communications, disruption of power system devices, just as some known examples.

This session invites multi-disciplinary, multi-scale contributions integrating seafloor mapping and sampling and regional geophysical studies that provide important constraints on the life cycle of oceanic lithosphere from formation at mid ocean ridges to destruction in subduction trenches, and all the processes modifying between its birth and death. By studying the seafloor and the underlying oceanic crust and lithosphere across diverse plate tectonic environments, we can gain a deeper appreciation of the role of ocean-plate tectonics for the large-scale structure, evolution and functioning of Earth.
It was the pioneering work of Marie Tharp, who’s physiographic maps of the seafloor revealed some of the largest, yet previously unknown bathymetric features on Earth: mid-ocean ridges, fracture zones, transform faults, seamounts and hotspot tracks, and trenches. Compiling bathymetric profiles along shiptracks, she carried out detailed, systematic mapping and produced a striking visualization of these features, the ‘physiographic diagrams’, that had a profound and lasting contribution to plate tectonics and marine geosciences. Today, initiatives such as the Nippon Foundation - GEBCO Seabed 2030 project and IODP 2050 open new avenues to address unresolved questions in oceanic plate tectonics, in addition to mapping and filling the gaps in the world ocean’s bathymetric maps.
Contributions to this session may address (but are not limited to) the following questions:
how does oceanic crust form at both fast and slow spreading mid-ocean ridges?
what controls seafloor morphology and how the different processes interact?
how does the asthenospheric mantle get structurally exhumed at ultraslow spreading ridges
how do subduction zones initiate?
how do marginal and full-scale ocean basins evolve?
how does oceanic crust accrete and vary along ~60,000 km of the mid-ocean ridges?
how is oceanic crust chemically, physically, and biologically altered as it matures; and what fraction may or may not be recycled into the mantle?
why is the oceanic crust so variable if the process forming it is the same in principle?
Geomechanics has been demonstrated over the past 30 years as having key importance for the safe and sustainable usage of underground environments. In particular, knowledge of geomechanics is critical for exploration and production of geothermal energy, groundwater, hydrocarbon, and mineral resources. Geomechanics play the central role in any underground storage (such as natural gas, CO2 and H2) and disposal of nuclear or toxic waste. The main goal of this session is therefore to bring together researchers from various engineering and geo-disciplines to share their knowledge in recent advancements in experimental, numerical, theoretical and field application of geomechanics. A particular focus is on the large uncertainties that are often associated with geomechanical measurements or models. In addition to abstracts that exclusively aim at uncertainty quantification and/or reduction at least a discussion of uncertainties is encouraged in every abstract.

Scientific drilling through the International Ocean Discovery Program (IODP) and the International Continental Scientific Drilling Program (ICDP) continues to provide unique opportunities to investigate the workings of the interior of our planet, Earth’s cycles, natural hazards and the distribution of subsurface microbial life. The past and current scientific drilling programs have brought major advances in many multidisciplinary fields of socio-economic relevance, such as climate and ecosystem evolution, palaeoceanography, the deep biosphere, deep crustal and tectonic processes, geodynamics and geohazards. This session invites contributions that present and/or review recent scientific results from deep Earth sampling and monitoring through ocean and continental drilling projects. Furthermore, we encourage contributions that outline perspectives and visions for future drilling projects, in particular projects using a multi-platform approach.

After the PhD, a new challenge begins: finding a position where you can continue your research or a
job outside academia where you can apply your advanced skills. This task is not
always easy, and frequently a general overview of the available positions is missing. Furthermore,
in some divisions, up to 70% of PhD graduates will go into work outside of academia. There are many
different careers which require or benefit from a research background. But often, students and
early career scientists struggle to make the transition due to reduced support and networking.
In this panel discussion, scientists with a range of backgrounds give their advice on where to find
jobs, how to transition between academia and industry and what are the pros and cons of a career
inside and outside of academia.
In the final section of the short course, a Q+A will provide the audience with a chance to ask
their questions to the panel. This panel discussion is aimed at early career scientists but anyone
with an interest in a change of career will find it useful. An extension of this short course will
run in the networking and early career scientist lounge, for further in-depth or
one-on-one questions with panel members.

The dynamics and evolution of Earth’s surface and interior are controlled by a spectrum of processes covering a wide range of length (i.e. from kilometers down to a few ångströms) and time scales (i.e. from billions of years down to picoseconds). Microstructures in planetary materials (e.g., fabrics, textures, grain sizes and distributions, shapes, cracks etc) can be used to infer, identify, and quantify metamorphic, magmatic or diagenetic processes. Coupling these microscale processes with larger scale, planetary phenomena (e.g. formation of plate boundaries or mantle convection) remains one of the key challenges in solid Earth geosciences. Fundamentally, processes such as grain size reduction, grain growth, phase changes, and the development of crystallographic preferred orientations modify the rheological properties of rocks and minerals, providing key information on the dynamics of small- to large-scale geodynamic processes. In this session, we invite contributions investigating microstructures and textures in field samples, laboratory experiments, and numerical modeling with the aim to constrain deformation processes of Earth’s surface and interior across multiple length scales.

Understanding the current and past state of stress is key to comprehend the rheological behavior of the crust, with numerous implications spanning from geodynamics to microstructure developments, and applications spanning from seismogenesis to resource distribution. The current state of stress is mainly assessed on seismic focal mechanisms, fault monitoring and slip inversion, borehole failure and imaging, and methods such as hydraulic fracturing to determine the magnitude of the applied stress. Paleopiezometry techniques rely on experimental and/or analytical approaches that link a finite deformation to an applied stress magnitude. Such technique allows to reconstruct past stress magnitude, orientation and regime on long time-scales. This session aims at picturing the state-of-the-art of the stress determination in the crust, whether it is the current stress or the past stress. We welcome any contribution that reconstructs regional state of stress in the crust by the mean of current measurement or paleopiezometry techniques, and that uses experimental or analytical/numerical approaches to predict stress distribution in rocks.

Faults and fracture zones are fundamental features of geological reservoirs that control the physical properties of the rock. As such, understanding their role in in-situ fluid behaviour and fluid-rock interactions can generate considerable advantages during exploration and management of reservoirs and repositories.
Physical properties such as frictional strength, cohesion and permeability of the rock impact deformation processes, rock failure and fault/fracture (re-)activation. Faults and fractures create fluid pathways for fluid flow and allow for increased fluid-rock interaction.
The presence of fluids circulating within a fault or fracture network can expose the host rocks to significant alterations of the mechanical and transport properties. This in turn can either increase or decrease the transmissibility of a fracture network, which has implications on the viability and suitability of subsurface energy and storage projects. Thus, it is important to understand how fluid-rock interactions within faults and fractures may alter the physical properties of the system during the operation of such projects. This is of particular interest in the case of faults as the injection/ remobilisation of fluids may affect fault/fracture stability, and therefore increase the risk of induced seismicity and leakage.
Fieldwork observations, monitoring and laboratory measurements foster fundamental understanding of relevant properties, parameters and processes, which provide important inputs to numerical models (see session “Faults and fractures in geoenergy applications 1: Numerical modelling and simulation”) in order to simulate processes or upscale to the reservoir scale. A predictive knowledge of fault zone structures and transmissibility can have an enormous impact on the viability of geothermal, carbon capture, energy and waste storage projects.
We encourage researchers on applied or interdisciplinary energy studies associated with low carbon technologies to come forward for this session. We look forward to interdisciplinary studies which use a combination of methods to analyse rock deformation processes and the role of faults and fractures in subsurface energy systems, including but not restricted to outcrop studies, monitoring studies, subsurface data analysis and laboratory measurements. We are also interested in research across several different scales and addressing the knowledge gap between laboratory scale measurements and reservoir scale processes.
The goal of this session is to reconcile short-time/small-scale and long-time/large-scale observations, including geodynamic processes such as subduction, collision, rifting, or mantle lithosphere interactions. Despite the remarkable advances in experimental rock mechanics, the implications of rock-mechanics data for large temporal and spatial scale tectonic processes are still not straightforward, since the latter are strongly controlled by local lithological stratification of the lithosphere, its thermal structure, fluid content, tectonic heritage, metamorphic reactions, and deformation rates.
Mineral reactions have mechanical effects that may result in the development of pressure variations and thus are critical for interpreting microstructural and mineral composition observations. Such effects may fundamentally influence element transport properties and rheological behavior.
Here, we encourage presentations focused on the interplay between metamorphic processes and deformation on all scales, on the rheological behavior of crustal and mantle rocks, and time scales of metamorphic reactions in order to discuss
(1) how and when up to GPa-level differential stress and pressure variations can be built and maintained at geological timescales and modeling of such systems,
(2) deviations from lithostatic pressure during metamorphism: fact or fiction?
(3) the impact of deviations from lithostatic pressure on geodynamic reconstructions.
(4) the effect of porous fluid and partial melting on the long-term strength.
We, therefore, invite the researchers from different domains (rock mechanics, petrographic observations, geodynamic and thermo-mechanical modeling) to share their views on the way forward for improving our knowledge of the long-term rheology and chemo-thermo-mechanical behavior of the lithosphere and mantle.
Reactions between fluids and rocks have a fundamental impact on many of the natural and geo-engineering processes in crustal settings. Examples of such natural processes are localization of deformation, earthquake nucleation caused by high pressure fluid pulses, as well as metamorphic reactions and rheological weakening triggered by fluid flow, metasomatism and fluid-mediated mass transport. Moreover, the efficiency of many geo-engineering processes is partly dependent on fluid-rock interactions, such as hydraulic fracturing, geothermal energy recovery, CO2 storage and wastewater injection. All our observations in the rock record are the end-product of all metamorphic, metasomatic and deformation changes that occurred during the interaction with fluid. Therefore, to investigate and understand these complex and interconnected processes, it is required to merge knowledge and techniques deriving from several disciplines of the geosciences.
We invite multidisciplinary contributions that investigate fluid-rock interactions throughout the entire breadth of the topic, using fieldwork, microstructural and petrographic analyses, geochemistry, experimental rock mechanics, thermodynamic modeling and numerical modeling.

This session aims to discuss recent advances in our understanding of the mechanical, structural, and seismic properties of the lower crust and upper mantle. Earth’s lithosphere is defined by its rheological and mechanical stability. Both shear localization and seismic instabilities are frequently observed through regional seismicity, laboratory experiments, numerical models,, and field observations, e.g., pseudotachylyte-bearing faults. In contrast to the shallow crust, dominated by brittle deformation, localized faulting, and frictional sliding, deformation observed in the mid- to lower- crust and upper mantle often displays localized faulting alongside more distributed flow and evidence for a variable mix of brittle and plastic deformation mechanisms. Because brittle and plastic deformation take place simultaneously over different time scales, the interplay between them is complex, and the resulting semi-brittle deformation style is still poorly understood. However, numerous enigmatic deformation phenomena, including slow-slip and lower crustal earthquakes, coincide with depths that either fall within, or mark the boundaries of, the semi-brittle field -- the brittle to ductile and the ductile to plastic transitions. We encourage geoscientists from across experimental geophysics, structural geology, seismology, and geodynamics with an interest in the interplay between different deformation mechanisms to contribute to this session.

Imaging both fluid-filled fault networks and surrounding heterogeneous crust with geophysical methods is especially challenging. In these settings, fluids interact with deformation-induced seismic sources, influencing both nucleation and development of seismic sequences.
Imaging and characterizing both seismogenic structures and elastic and anelastic properties of the surrounding medium is key to understanding wider tectonic and small-scale deformation processes. Understanding the geometry and kinematics of crustal-scale faults from field observations is also critical for many green-energy applications (e.g., geothermal energy, CO2 storage, mining for minerals important for battery production). This session aims to provide an overview of techniques and applications aimed at characterizing both active and ancient seismogenic fault networks at local and regional scales.
In this session we aim to bring together passive and active-source seismologists to discuss new studies that image and characterize seismically active and ancient faults and fault networks. We welcome contributions from velocity tomography, attenuation tomography (coda, t* method, direct wave attenuation), source imaging and characterization (absolute and relative location techniques, focal mechanism and stress drop analysis, …), active-source seismic techniques (reflection, refraction, integrated drilling data, …), along with multidisciplinary studies. We particularly welcome contributions from early-career researchers and those using novel techniques (e.g., data mining and machine learning).
Naturally fractured reservoirs are of great importance in various disciplines such as hydrogeology, hydrocarbon reservoir management, nuclear waste repositories, CO2 storage and geothermal reservoir engineering. This session addresses novel ideas as well as established concepts for the representation and numerical simulation of discontinuities and processes in fractured media.
The presence of fractures modifies the bulk physical properties of the original media by many orders of magnitudes and often introduces strongly nonlinear behaviour. Fractures also provide the main flow and transport pathways in the rock mass, dominating over the permeability of the rock matrix and creating anisotropic flow fields and transport.
Numerical modelling of such systems is especially challenging and often requires creative new ideas and solutions, for example the use of stochastic models. Understanding the hydraulic and mechanical properties of fractures and fracture networks thus is crucial for predicting the movement of any fluid such as water, air, hydrocarbons, or CO2.
The geologist toolboxes for modelling fractured rocks and simulating processes in fractured media experiences constant extension and improvement. Contributions are especially welcome from the following topics:
• Deterministic or stochastic approaches for structural construction of fractured media
• Continuous or discontinuous (DFN) modelling methods representing static hydraulic and/or mechanical characteristics of fractured media
• Simulation of dynamic processes, hydraulic and/or mechanical behaviour and THMC coupling in fractured media
• Deterministic and stochastic inversion methods for calibrating numerical models of fractured media
• Numerical modelling concepts of accounting for fractured properties specifically in groundwater, petroleum or geothermal management applications
We encourage researchers to elaborate on applied projects on the role of faults and fractures in subsurface energy systems in our session. We are interested in research across different scales and disciplines and welcome warmly ECS.
With field and laboratory studies from the same subjects please refer to our co-session ERE 5.2 “Faults and fractures in geoenergy applications – monitoring, laboratory and field work results".

Numerical modeling of earthquakes provides new approaches to apprehend the physics of earthquake rupture and the seismic cycle, seismic wave propagation, fault zone evolution and seismic hazard assessment.
Recent advances in numerical algorithms and increasing computational power enable unforeseen precision and multi-physics components in physics-based earthquake simulation but also pose challenges in terms of fully exploiting modern supercomputing infrastructure, realistic parameterization of simulation ingredients and the analysis of large synthetic datasets while advances in laboratory experiments link earthquake source processes to rock mechanics.
This session aims to bring together modelers and data analysts interested in the physics and computational aspects of earthquake phenomena and earthquake engineering. We welcome studies focusing on all aspects of seismic hazard assessment and the physics of earthquakes - from slow slip events, fault mechanics and rupture dynamics, to wave propagation and ground motion analysis, to the seismic cycle and inter seismic deformation - and studies which further the state-of-the art in the related computational and numerical aspects.
The Mediterranean region holds a plate boundary zone undergoing final closure between two major plates, Africa and Eurasia. The active tectonics and geodynamics of the Mediterranean region result from the interaction of subduction and collision processes, deformation of the slabs, mantle flow, and extrusion of crustal blocks. These geodynamic processes have a transient nature and their changes affect the regional tectonics.
This session focuses on two aspects of the Mediterranean recent active tectonics and geodynamics:
(1) how (active) geodynamic mechanisms define the current structure and recent evolution of Mediterranean Arc systems.
(2) how the surface deformation is accommodated, both on fault local scale (e.g. the seismic cycle and kinematics of active faults) and in the larger (e.g. regional kinematics and relation the surface deformation to the deeper processes).
We welcome contributions from a wide range of disciplines including, but not limited to seismology, tectonic geodesy, remote sensing, paleoseismology, tectonic geomorphology, active tectonics, structural geology, and geodynamic modeling.
We strongly encourage the contribution of early career researchers.
This session is formed by merging of TS sessions: "Active tectonics and geodynamics of the Eastern Mediterranean" & "Recent geodynamic evolution and active tectonics of Mediterranean Arcs"

Regions of slow deformation and low strain, often located in continental interiors or intraplate settings, can present substantial, under-recognised seismic hazards. The styles, rates, and spatial patterns of strain distribution and seismicity in these areas are often dissimilar to plate-boundary regions, where most of our current understanding of deformation drivers was derived. Challenges in studying slowly deforming regions include: 1) poor surface exposure and/or preservation of Quaternary-active structures, 2) long earthquake recurrence intervals, and 3) complex fault geometries, mechanics, and deformation histories, often including reactivation of inherited structures.
Interdisciplinary studies combining a diverse range of geoscientific disciplines have helped us develop a better understanding of drivers of low strain deformation. In this session, we want to explore the roles, behaviours, and associated seismic hazards of short-to-long-term active deformation and key inherited tectonic structures in these regions. We seek studies from around the globe that illuminate our understanding of these complex zones using field-based analyses, geophysics, seismology, active tectonics, geomorphology, remote sensing, numerical and analogue modelling, sedimentology, and geochronology. We particularly encourage interdisciplinary presentations, thought-provoking studies that challenge conventional wisdoms, and submissions from early career researchers.
Public information:
The last four decades of earthquake science have relied on a combination of geophysical, remote sensing, and field techniques to shed light on earthquake hazard near active plate boundaries, where the majority of earthquakes occur. However, we still lack data and explanatory models for earthquake hazard in regions located far away from plate boundary settings. These slowly deforming regions pose a significant hazard to the livelihood and security of nearby communities.
Our session seeks to bring together geoscientists from across disciplinary backgrounds to discuss challenges and recent advances in understanding earthquake processes in these regions, with an eye towards improving hazard assessment in the 21st century.
Since the beginning of the XXI Century, our society has witnessed a number of catastrophic offshore earthquakes with devastating consequences (e.g., Sumatra 2004, Japan 2010, Palu 2018 or Samos-Izmir 2020). Localizing the offshore active faults and understanding their earthquake history is key to improve modern probabilistic seismic hazard assessment (PSHA) and, thus, to be able to mitigate the consequences of future offshore events.
In the last few years, the development of new geological and geophysical instrumentation has made possible the acquisition of offshore data at various scales with unprecedented detail and resolution, as for example deep and shallow boreholes, wide-angle seismic profiles, tomography, 3D and 2D seismic reflection surveys, or ultra-high-resolution bathymetry. In addition, these instrumentation is also allowing to carry on long-term monitoring (i.e., seismology, seafloor geodesy or pore pressure) and repeat surveys (i.e., time-lapse bathymetry). These new data is leading to achieve major advances in the study of active faults in offshore areas and the characterization of their recent activity, seismogenic potential and related secondary effects (i.e., mass wasting).
The aim of this session is to compile studies that focus on the use of geological and geophysical data to identify offshore active structures, to quantify the deformation that they are producing in the seafloor, to evaluate their seismogenic and tsunamigenic potential, to characterize possibly related secondary effects such as submarine mass transport deposits, and to estimate the related hazards. Accordingly, we welcome studies and/or new perspectives and ideas in marine active tectonics, turbidite paleoseismology, offshore on-fault paleoseismology or tectonic geomorphology, and seismotectonics, from local to regional scale analysis. We also encourage the submission of studies that explore the application of new ideas to estimate coseismic seafloor deformation, to constrain earthquake timing, long-term offshore monitoring of active structures, as well as the application of fault geometrical and kinematic reconstruction to seismic and tsunami hazard analysis.

Regular talks will have 7 minutes each (5 presentation + 2 questions). Invited talk (Prof. Micheal Strasser) will have 10 minutes for the talk followed by a 12 minutes period for questions, discussion and closing of the session.

Tectonic faults accommodate plate motion through various styles of seismic and aseismic slip spanning a wide range of spatiotemporal scales. Understanding the mechanics and interplay between seismic rupture and aseismic slip is central to seismotectonics as it determines the seismic potential of faults. In particular, unraveling the underlying physics controlling these styles of deformation bears a great deal in earthquakes hazards mitigation especially in highly urbanized regions. We invite contributions from observational, experimental, geological and theoretical studies that explore the diversity and interplay among seismic and aseismic slip phenomena in various tectonic settings, including the following questions: (1) How does the nature of creeping faults change with the style of faulting, fluids, loading rate, and other factors? (2) Are different slip behaviors well separated in space, or can the same fault areas experience different failure modes? (3) Is there a systematic spatial or temporal relation between different types of slip?

Recently, there have been significant breakthroughs in the use of fiber-optic sensing techniques to interrogate cables at high precision both on land and at sea as well as in boreholes and at the surface. Laser reflectometry using both fit-to-purpose and commercial fiber-optic cables have successfully detected a variety of signals including microseism, local and teleseismic earthquakes, volcanic events, ocean dynamics, etc. Other laser-based techniques can be used to monitor distributed strain, temperature, and even chemicals at a scale and to an extent previously unattainable with conventional geophysical methods.
We welcome any contributions to recent development in the fields of applications, instrumentation, and theoretical advances for geophysics with fiber-optic sensing techniques. These may include - but are not limited to - application of fiber-optic cables or sensors in seismology, geodesy, geophysics, natural hazards, oceanography, urban environment, geothermal application, etc. with an emphasis on laboratory studies, large-scale field tests, and modeling. We also encourage contributions on data analysis techniques, machine learning, data management, instruments performances and comparisons as well as new experimental field studies.
One of the key challenges in earthquake geology is the characterization of the spatial distribution of fault-slip and its partitioning during the coseismic, interseismic, and post-seismic periods. We now have new approaches and techniques for validating the assumption that repeated seismic cycles accommodate the long-term tectonic strain and for disentangling such a complex strain partitioning in both time and space. In fact, the temporal and spatial slip accumulation for an active fault is essential to understand the hazard posed by the fault. As a matter of fact, destructive earthquakes are infrequent along any active fault and this is an inherent limitation to knowledge towards reconstructing the seismic cycle. For example, the occurrence of the 2021 Alaska earthquake Mw 8.2 within the rupture zone of the Mw 8.2 1938 Alaska earthquake, and 2021 Haiti earthquake Mw 7.2 within the same fault zone of the 2010 earthquake Mw 7.0 (which claimed 300,000 lives), reflects how much the characterization of the seismic cycle and earthquakes’ recurrence is critical for cities and regions which are under the constant seismic threat.
Modern techniques such as Remote Sensing, Geodesy, Geomorphology, Paleoseismology, and Geochronology play a vital role in constraining part of or full seismic cycles, with increased accuracy and temporal coverage of the long-term deformation. To fully understand these observations there is a need for a better understanding and integration of such techniques to be applied across different fault systems, globally.
The goal of this session is to bring together innovative approaches and techniques, to take a comprehensive look at the earthquake cycle for plate boundary fault systems to fault systems sitting far away from the plate boundary.
Earthquake swarms are characterized by a complex temporal evolution and a delayed occurrence of the largest magnitude event. In addition, seismicity often manifests with intense foreshock activity or develops in more complex sequences where doublets or triplets of large comparable magnitude earthquakes occur. The difference between earthquake swarms and these complex sequences is subtle and usually flagged as such only a posteriori. This complexity derives from aseismic transient forcing acting on top of the long-term tectonic loading: pressurization of crustal fluids, slow-slip and creeping events, and at volcanoes, magmatic processes (i.e. dike and sill intrusions or magma degassing). From an observational standpoint, these complex sequences in volcanic and tectonic regions share many similarities: seismicity rate fluctuations, earthquakes migration, and activation of large seismogenic volume despite the usual small seismic moment released. The underlying mechanisms are local increases of the pore-pressure, loading/stressing rate due to aseismic processes (creeping, slow slip events), magma-induced stress changes, earthquake-earthquake interaction via static stress transfer or a combination of those. Yet, the physics behind such processes and the ultimate reasons for the occurrence of swarm-like rather than mainshock-aftershocks sequences, is still far beyond a full understanding.
This session aims at putting together studies of swarms and complex seismic sequences driven by aseismic transients in order to enhance our insights on the physics of such processes. Contributions focusing on the characterization of these sequences in terms of spatial and temporal evolution, scaling properties, and insight on the triggering physical processes are welcome. Multidisciplinary studies using observation complementary to seismological data, such as fluid geochemistry, deformation, and geology are also welcome, as well as laboratory and numerical modeling simulating the mechanical condition yielding to swarm-like and complex seismic sequences.

Geomorphic and geologic observations at the Earth's surface reflect the combined effects of mantle, lithospheric, and surface processes. Hence surface observations provide important constraints on mantle convection patterns and plume-plate interactions both at plate boundaries and in intraplate settings through space and time. These observations complement geophysical data and are important constraints for theoretical models and numerical simulations. For instance, at plate boundaries, surface observations can provide key constraints on the rheology and kinematics of lithospheric and mantle processes. In both plate boundary and intraplate settings, mantle plumes can trigger continental rifting and break-up, subduction initiation, orogeny, microcontinent formation, and/or the development of dynamic topography. However, using surface observations to constrain mantle processes is complicated by (1) our as yet incomplete understanding of how mantle dynamics manifest at the surface, and (2) spatio-temporal variations in tectonic processes, climate, isostatic adjustment, lithology, biota, and human alteration of landscapes. In this session, we aim to bring together researchers interested in mantle-surface and plume-plate interactions. We welcome studies that cover a range of techniques from data-driven approaches to numerical modelling or laboratory experiments.
We hope this session will provide opportunities for presenters from a range of disciplines, demographics, and stages of their scientific career to engage in this exciting and emerging problem in Earth Science.
It is now well known that the coupling between tectonics, climate and surface processes governs the dynamics of mountain belts and basin. However, the amplitude of these couplings and their exact impact on mountain building are less understood. First order quantitative constraints on this coupling are therefore needed. They can be provided by geomorphic and sedimentary records including longitudinal river profiles, fluvial terraces, downstream fining trends, growth strata, sediment provenance, sequence stratigraphy, and changing depositional environments. Moreover, the increasing integration of geochronological methods for quantifying erosion rates and source-to-sink sediment transfer with landscape evolution, stratigraphic, climatic, and tectonic models allows to advance our understanding of the interactions between surface processes, climate and tectonic deformation.
We invite contributions that use geomorphic and/or sedimentary records to understand tectonic deformation, climate histories, and surface processes, and welcome studies that address their interactions and couplings at a range of spatial and temporal scales. In particular, we encourage coupled catchment-basin studies that take advantage of numerical/physical modelling, geochemical tools for quantifying rates of surface processes (cosmogenic nuclides, low-temperature thermochronology, luminescence dating) and high resolution digital topographic and subsurface data. We invite contributions that address the role of surface processes in modulating rates of deformation and tectonic style, or of tectonics modulating the response of landscapes to climate change.

Continental rifting is a complex process spanning from the inception of extension to continental rupture or the formation of a failed rift. This session aims at combining new data, concepts and techniques elucidating the structure and dynamics of rifts and rifted margins. We invite submissions highlighting the time-dependent evolution of processes such as: initiation and growth of faults and ductile shear zones, tectonic and sedimentary history, magma migration, storage and volcanism, lithospheric necking and rift strength loss, influence of the pre-rift lithospheric structure, rift kinematics and plate motion, mantle flow and dynamic topography, as well as break-up and the transition to sea-floor spreading. We encourage contributions using multi-disciplinary and innovative methods from field geology, geochronology, geochemistry, petrology, seismology, geodesy, marine geophysics, plate reconstruction, or numerical or analogue modelling. Special emphasis will be given to presentations that provide an integrated picture by combining results from active rifts, passive margins, failed rift arms or by bridging the temporal and spatial scales associated with rifting.

The evolution of extensional tectonic settings is often envisioned as an in-plane process. Yet in nature extensional settings are often characterised by processes occurring in 3D and over protracted timescales. Their complex deformation histories can be attributed to superimposed events that involve pre-existing heterogeneities with different orientations, temporal changes in plate motion or, very often, a combination of the above. These factors result in multi-phase rifting, rotational or oblique rift kinematics, complex fault growth and interaction, lateral variations in structural style and rift propagation, as well as intricate strain partitioning patterns, among others. These complexities are commonly observed in both ancient and currently active extensional settings, but deciphering the temporal evolution of inherently 3D tectonic systems from limited (and often 2D) datasets can pose a significant challenge.
The aim of this session is to bring together new research from disciplines focussing on the 3D evolution of extensional tectonic settings at various spatio-temporal scales, with important implications for basin development, magmatism and surface processes. We encourage contributions from a wide range of fields, including geophysics, paleomagnetism, geodesy, geochronology, tectonics, structural geology, and analogue and numerical modelling in order to promote cross-disciplinary discussions that lead to new insights on the topic.

During the past 20 years, extensive research at present-day rifted margins and at fossil remnants preserved at orogenic belts has demonstrated that rifting is a complex and dynamic process. Extension can be dominated by poly-phase rifting, in which case the structure of rifted margins results from a unique kinematic event but the succession of several rift phases, resulting in a progressive migration and localisation of deformation. Multi-stage extension, however, evolves through independent rift events, which develop with distinct kinematic frameworks, leading to different but overlapping rift systems. Crustal domains and overlying rift basins are genetically linked in poly-phase rift systems, which include in-sequence syn-rift units and bounding extensional structures. In multi-stage extension, however, rift systems are out of sequence, and each of the rift systems displays a particular crustal structure and different rift basins and bounding structures. Thermal, magmatic and structural inheritance condition the onset of rifting, while inherited rift templates guide successive rift events. Complex 3D rift templates ultimately control subsequent compressional reactivation processes, leading to passive margin inversion, subduction initiation and mountain building.
This session aims to attract work that focuses on the analysis of the architecture of worldwide rift systems and related spatial and temporal evolution of rifting processes using geophysical data, fieldwork observations and associated geochemical and thermochronological studies, numerical and analogue modelling techniques, and plate kinematic reconstructions. This will enable us to compare and discuss the architecture of rift templates and their role in the evolution of extension as well as the subsequent convergence.

The North-Atlantic-Arctic realm hosts vast extended continental shelves bordering old land masses, two Large Igneous Provinces (LIPs), one of which is the largest known sub-marine LIP (Alpha-Mendeleev Ridge) and a complex ocean spreading systems, including the slowest mid-ocean spreading ridge (Gakkel Ridge) and several extinct ocean basins.
Over recent decades, increasing scientific interest has led to the acquisition of vast quantities of geological and geophysical data across the North Atlantic-Arctic realm, yet our understanding of the region has become, if anything, even more controversial than it was before. The geodynamic and geomorphological processes acting here (and globally) are key to the understanding of the structure, geodynamic and paleolandscape evolution, hazards and resources in the region.
This session provides a forum for discussions and reviews of a variety of problems linked to the North Atlanitc-Arctic geodynamics such as plate tectonic, geodynamic, compositional, thermal, structural and landscape models, configuration of sedimentary basin and to propose additional experiments that can test these models. We welcome contributions from all relevant disciplines, including, but not limited to, plate tectonics, geophysics, geodynamic modelling, igneous, metamorphic and structural geology, palaeomagnetism, sedimentology, geomorphology, geochronology, thermochronology, geochemistry and petrology.

Since approximately 90% of the seismic moment released by earthquakes worldwide occurs near subduction zones, it is crucial to improve our understanding of seismicity and the associated seismic hazard in these regions. Seismicity in subduction zones takes many forms, ranging from relatively shallow seismicity on outer-rise and splay faults and the megathrust to intermediate-depth (70-300 km) and deep events (>300 km). While most research on subduction earthquakes focuses on the megathrust, all these different seismic events contribute to the seismic hazard of a subduction zone.
This session aims to integrate our knowledge on different aspects of subduction zone seismicity to improve our understanding of the interplay between such events and their relationship to subduction dynamics. We particularly invite abstracts that use geophysical and geological observations, laboratory experiments and/or numerical models to address questions such as: (1) What are the mechanisms behind intraplate seismicity? (2) How do outer-rise and splay fault seismicity relate to the seismogenic behaviour of the megathrust? (3) How do slab dynamics influence both shallow and deep seismicity?

Fold-and-thrust belts and accretionary prisms are some of the most recognizable large-scale geological features occurring all around the globe. They mostly develop along convergent plate boundaries. Fold-and-thrust belts may also form along passive margins or other super-critical slopes by a gravitationally driven stress field. Fold-and-thrust belts may involve the basement of continental lithospheres to build entire mountain ranges or just the uppermost sedimentary sequence detaching along stratigraphic décollements. Although these different types of fold-and-thrust belts vary in spatial extent, longevity of their formation, and rock types involved, their dynamics and structural evolution strongly depends on the same internal and external effects, such as rheological and rock mechanical properties, temperature and surface processes, allowing to compare them with each other and to develop common mechanical predictions.
Fold-and-thrust belts have been intensely investigated to decipher their short- and long-term evolution. However, there are important questions that yet have to be fully understood: i) What is the effect of inherited structures within the basement, the upper sequence and potential décollements, and how can those inheritances be detected? ii) How are transient and long-term rheological/mechanical characteristics comparable during the formation of a fold-and-thrust belt? iii) Do present day fold-and-thrust belts reflect local, transient conditions, and how are large-scale, long-term tectonic processes affecting their evolution?
The here proposed session tackles to answer these questions by an interdisciplinary approach. We look forward to receive abstracts focusing on the short- and long-term dynamics and structural evolution of fold-and-thrust and belts by means of structural fieldwork, seismics and seismology, analogue and numerical modelling, rock mechanics, geomorphology and thermochronology as well as quantification of uncertainties in order to improve our understanding of fold-and-thrust belts across spatial and temporal scales.

The Phanerozoic orogenic belts of the circum-Mediterranean region stand out for their variety of tectonic styles, metamorphic imprints, and orogenic evolution. The similar tectono-metamorphic history of the Variscan and Alpine orogenies, as well as the distinctive traits of different sectors of these belts, make them unique to investigate orogenic processes through time and space. Circum-Mediterranean belts are, indeed, the result of the opening and closure of separate oceanic basins, of the complex interaction between microplates, and of the lateral transition to different subduction/collision zones, which marked different stages of their evolution. Over the last decades, the study of these orogenic belts showed how paleomargin geometries, type and dip of subduction zones, coupling or decoupling between the crust and the mantle, heat flux, orogenic wedge processes, interplay between erosion and sedimentation, and mantle dynamics influence mountain building processes. All these variables combined control the mechanisms of deformation of the lithosphere steering the structural and topographic evolution of collision zones. The history and complexity of the circum-Mediterranean area represent an intriguing geological puzzle whose investigation permits to address fundamental questions on tectonic and geodynamic processes and to improve our understanding of the dynamics of the lithosphere.
This section is devoted to the investigation of these processes and mechanism in the circum- Mediterranean orogenic belts of the Variscan (Maures, Corsica and Sardinia block) and Alpine (Atlas, Alps, Apennines, Pyrenees, Dinarides; Hellenides) cycles. We welcome contributions on all aspects of mountain building that cover a multiscale range of observation from meso to microscopic scale (field working to microprobe) and offer different perspectives from geology (tectonics, stratigraphy, petrology, geochronology, geochemistry, and geomorphology), geophysics (seismicity, seismic imaging, seismic anisotropy, gravity), geodesy (GPS, InSAR), modelling (numerical and analogue), natural hazards (earthquakes, volcanism). We also encourage the submission of trans-disciplinary studies that integrate multiple methods to unfold the evolution of orogenic belts.

The Tethyan orogenic belt is one of the largest and most prominent collisional zones on Earth. The belt ranges from the Mediterranean in the west to Papua New Guinea in the east. It results from the subduction and closure of multiple basins of the Tethys Ocean and the subsequent collision of the African, Arabian and Indian continental plates with Eurasia. Its long-lasting geological record of the opening and closure of oceanic basins, the accretion of arcs and microcontinents, the complex interactions of major and smaller plates, and the presence of subduction zones at different evolutionary stages, has progressively grown as a comprehensive test site to investigate fundamental plate tectonics and geodynamic processes with multiple disciplines. Advances in a variety of fields provide a rich and growing set of constraints on the crust-lithosphere and mantle structure and their physical and chemical characteristics, as well as the tectonics and geodynamic evolution of the Tethyan orogenic belt.
We welcome contributions presenting new insights and observations derived from different perspectives, including geology (tectonics, stratigraphy, petrology, geochronology, geochemistry, and geomorphology), geophysics (seismicity, seismic imaging, seismic anisotropy, gravity), geodesy (GPS, InSAR), modelling (numerical and analogue), natural hazards (earthquakes, volcanism). In particular, we encourage the submission of trans-disciplinary studies, which integrate observations across a range of spatial and temporal scales to further our understanding of plate tectonics as a planetary process of fundamental importance.
The Arabian Plate recorded several plate reorganizations from the Neoproterozoic to present, including the Cadomian and Angudan orogenies, Late Paleozoic rifting and Alpine Orogeny. Active tectonics are framing the Arabian Plate and produce a variety of structures, including extensional structures related to rifting of the Red Sea and Gulf and Aden, strike-slip structures at the Dead Sea and Owen transform faults and compressive structures related to the Zagros-Makran convergence zone. The Arabian Peninsula contains the planet’s largest hydrocarbon reservoirs, owing to its geological history as Gondwana’s passive margin during the Permo-Mesozoic. Moreover, the Semail Ophiolite as the largest exposed ophiolite on Earth offers a unique example of large-scale obduction and overridden sedimentary basins. This and the spectacular outcrop conditions make the Arabian Peninsula an important and versatile study area. Ongoing research and new methods shed new light on, e.g., mountain building processes and its geomorphological expression as well as hydrocarbon development/migration.
We invite contributions that utilize structural, geophysical, tectonic, geochronological, geomorphological, sedimentary, geochemical/mineralogical, and field geological studies from the Arabian Peninsula and surrounding mountain belts and basins. These studies may include topics dealing with structures/basin analyses of any scale and from all tectonic settings ranging from the Neoproterozoic until today.
Dynamic topography is an important component of topography produced by mantle flow beneath the lithosphere. Like other components topography, dynamic topography sheds control on the eustacy, coastline evolution, source-to-sink systems, and long-wavelength variations in topography within continental interior far away from plate margins. In this aspect, dynamic topography has played a vital role in exploring the relationships between plate subduction, mantle flow, and Earth surface process. The circum-Pacific domain has been undergoing multiple re-orientations in subduction and given rise to basin-mountain systems in both eastern (western North America and South America) and western (East Asia) Pacific continental margins since late Mesozoic. Prominent diversity between the modern mantle structures of East Asia and the Americas strongly indicate different plate subduction history; this difference in evolution of the plate tectonics and mantle structure is recorded in dynamic topography. Fully unraveling the four-dimensional dynamic topography and its implications for tectonics has been one of the major challenges in both East Asia and the Americas. To help understand this complex relationship, we welcome your contributions addressing topics that concentrate on (1) the formation/origin and evolution of mantle architecture, (2) spatial-temporal evolution of Earth’s surface topography, especially dynamic topography, (3) evolution of basin-mountain systems and their indication of plate subduction, and (4) 4-D geodynamic models of eastern and western Pacific continental margins and the other regions since late Mesozoic.

Subduction drives plate tectonics, generating the major proportion of subaerial volcanism, releasing >90% seismic moment magnitude, forming continents, and recycling lithosphere. Numerical and laboratory modeling studies have successfully built our understanding of many aspects of the geodynamics of subduction zones. Detailed geochemical studies, investigating compositional variation within and between volcanic arcs, provide further insights into systematic chemical processes at the slab surface and within the mantle wedge, providing constraints on thermal structures and material transport within subduction zones. However, with different technical and methodological approaches, model set-ups, inputs, and material properties, and in some cases conflicting conclusions between chemical and physical models, a consistent picture of the controlling parameters of subduction-zone processes has so far not emerged.
This session aims to follow subducting lithosphere on its journey from the surface down into the Earth's mantle and to understand the driving processes for deformation and magmatism in the over-riding plate. We aim to address topics such as: subduction initiation and dynamics; changes in mineral breakdown processes at the slab surface; the formation and migration of fluids and melts at the slab surface; primary melt generation in the wedge; subduction-related magmatism; controls on the position and width of the volcanic arc; subduction-induced seismicity; mantle wedge processes; the fate of subducted crust, sediments and volatiles; the importance of subducting seamounts, LIPs, and ridges; links between near-surface processes and slab dynamics and with regional tectonic evolution; slab delamination and break-off; the effect of subduction on mantle flow; and imaging subduction zone processes.
With this session, we aim to form an integrated picture of the subduction process, and invite contributions from a wide range of disciplines, such as geodynamics, modeling, geochemistry, petrology, volcanology, and seismology, to discuss subduction zone dynamics at all scales from the surface to the lower mantle, or in applications to natural laboratories.

Since 2015, the international AlpArray mission and related projects have generated a plethora of new data to test the hypothesis that mantle circulation driving plates’ re-organization during collision has both immediate and long-lasting effects on the structure, motion, earthquake distribution and landscape evolution in mountain belts. Links between Earth’s surface and mantle have been forged by integrating 3D geophysical imaging of the entire crust-mantle system, with geologic observations and modelling to provide a look both backwards and forwards in time, the 4th dimension. This integrated 4D approach, initially focused on the Alps, has been expanded to the Pannonian-Carpathian and Adriatic areas, and now includes the Apennines and Dinarides. A new initiative, AdriaArray, is underway to shed light on plate-scale deformation and orogenic processes in this dynamic part of the Alpine-Mediterranean chain. The forthcoming Drilling the Ivrea-Verbano zonE (DIVE) project bridges new observations across scales and investigates the evolution of the continental lower crust. This session provides an interdisciplinary platform for highlighting the newest results and open questions of the aforementioned projects, regions and themes.

Subduction is one of the primary mechanisms of fluid and element cycling between
the surface and mantle in the Earth. During subduction, metamorphism in the
downgoing plate and the consequent expulsion of fluids and generation of melts
drives mineralogical, geochemical, and rheological changes affecting the mechanical
behaviour of the subducting zone system. These fluids and melts play a key role in
the long-term geochemical evolution of the Earth by preferentially fractionating
elements from the slab and introducing them to the mantle wedge, volcanic arc, and
forearc. This process is particularly relevant for volatiles, such as carbon, which can have a profound influence on the habitability of the Earth's surface. This session aims to bring together the petrology, geochemistry, geodynamics, tectonics, and geochronology community by linking subduction zone inputs, outputs and mechanisms over a range of length and timescales. We especially encourage studies that constrain the conditions, durations, and geochemical evolution of metamorphic, metasomatic, and magmatic processes leading to the transfer of material from the slab into the mantle wedge, forearc, arc, and deep mantle. We encourage participation from scientists from all backgrounds and levels of experience.

Transform faults are one of the three types of plate boundaries required for Earth-like plate tectonics to operate. In these locations, plates move laterally in relation to each other without significant creation or destruction of plate material. Transform plate boundaries played a fundamental role in the development of the theory of plate tectonics. The concept of transform fault was introduced by Tuzo Wilson as the final piece of a puzzle that allowed connecting ridges to convergent zones and close the circumference of lithospheric plates. Wilson recognized that transform faults were different from the already known continental transcurrent faults (or nonlithospheric strike-slip faults). The term transform plate boundary is since then been used to define a lithospheric strike-slip fault zone that constitutes a plate boundary. The term is also used more loosely to define strike-slip boundaries of diffuse tectonic blocks or microplates. At smaller orders, strike-slip faults exist in all kinds of environments and at all scales, accommodating the lateral movement of tectonic blocks and linking other kinds of faults. Transform plate boundaries can exist in both continental or oceanic lithosphere, leading to markedly different strain distribution patterns and seismic activity. This is particularly true for the case of oceanic transform faults, which result from the own growth of the plates. Due to their remote locations, the rheological structure and behavior of oceanic transform faults are still largely unknown. The fact that they exist in oceanic environments suggests that they are prone to constant fluid circulation and alteration, potentiated by the chemical reactions between rocks and circulating fluids. Transform faults have also traditionally been perceived as places of low to moderate magnitude seismicity, but recent events have shown that these structures can generate very high magnitude hazardous events. Examples include the 2010 Haiti earthquake and the 1941 M 8.4 earthquake along the Gloria Fault. In this session, we aim to discuss the evolution of oceanic and continental transform and strike-slip faults. We welcome studies on structural geology, marine geology, geochemistry, petrology, remote sensing, tectonics, seismology and hazards, as well as modelling studies, using both analogue and numerical approaches. Associated processes such as shear localization, serpentinisation, biogenic activity, fluid migration and extrusion are also very welcome.

Geologic processes are generally too slow, too rare, or too deep to be observed in-situ and to be monitored with a resolution high enough to understand their dynamics. Analogue experiments and numerical simulation have thus become an integral part of the Earth explorer's toolbox to select, formulate, and test hypotheses on the origin and evolution of geological phenomena.
To foster synergy between the rather independently evolving experimentalists and modellers we provide a multi-disciplinary platform to discuss research on tectonics, structural geology, rock mechanics, geodynamics, volcanology, geomorphology, and sedimentology.
We therefore invite contributions demonstrating the state-of-the-art in analogue and numerical / analytical modelling on a variety of spatial and temporal scales, varying from earthquakes, landslides and volcanic eruptions to sedimentary processes, plate tectonics and landscape evolution. We especially welcome those presentations that discuss model strengths and weaknesses, challenge the existing limits, or compare/combine the different modelling techniques to realistically simulate and better understand the Earth's behaviour.

Geological and geophysical data sets are in essence the result of physical processes governing the Earth’s evolution. Such data sets are widely varied and range from the internal structure of the Earth, plate kinematics, composition of geomaterials, estimation of physical conditions, dating of key geological events, thermal state of the Earth to more shallow processes such as natural and “engineered” reservoir dynamics and waste sequestration in the subsurface.
Combining such data with process-based numerical models is required for our understanding of the dynamical Earth. Process-based models are powerful tools to predict the evolution of complex natural systems resolving the feedback among various physical processes. Integrating high-quality data into numerical simulations leads to a constructive workflow to further constrain the key parameters within the models. Innovative inversion strategies, linking forward dynamic models with observables, is therefore an important research topic that will improve our knowledge of the governing physical parameters.
The complexity of geological systems arises from their multi-physics nature, as they combine hydrological, thermal, chemical and mechanical processes (e.g. thermo-mechanical convection). Multi-physics couplings are prone to nonlinear interactions ultimately leading to spontaneous localisation of flow and deformation. Understanding the couplings among those processes therefore requires the development of appropriate tools to capture spontaneous localisation and represents a challenging though essential research direction.
We invite contributions from the following two complementary themes:
1. Computational advances associated with
- alternative spatial and/or temporal discretisation for existing forward/inverse models
- scalable HPC implementations of new and existing methodologies (GPUs / multi-core)
- solver and preconditioner developments
- AI / Machine learning-based approaches
- code and methodology comparisons (“benchmarks”)
- open source implementations for the community
2. Physics advances associated with
- development of partial differential equations to describe geological processes
- inversion strategies and adjoint-based modelling
- numerical model validation through comparison with observables (data)
- scientific discovery enabled by 2D and 3D modelling
- utilisation of coupled models to explore nonlinear interactions

The rates and dates of processes occurring at tectonic-plate scale can be quantified using evidence derived from actively deforming settings, including geomorphic markers (e.g., topography and rivers, fluvial deposits, marine terraces) and sedimentary archives (e.g., syntectonic sedimentation, stratigraphic evidence).
When used as key natural laboratories at adequate time spans, such evidence provides essential clues to understand large-scale tectonics. These focused studies may contribute to unravel the motion, deformation, and evolution of tectonic plates, as well as changes in their potential geodynamics and boundary conditions.
We invite contributions focusing on understanding the dynamics and evolution of deforming plate interiors and active plate boundaries through interdisciplinary, geomorphic, or sedimentary data-based approaches. We welcome all types of studies that aim to quantify the rates of active plate deformation and the dates of tectonic events, regardless of their spatio-temporal scale or methodology.

Birth, evolution, and demise of sedimentary basins result from the interplay of several factors such as the geodynamic/tectonic regime, stress field, thickness and thermal state of the lithosphere, rheological properties of both basement and sedimentary fill, and faults architecture. Integrated studies, including the analyses of structural setting and thermal maturity of stratigraphic successions, have shown to be successful in unravelling the tectonic evolution of active basins as well as fossil ones that have been later incorporated into orogenic belts.
In this session, we welcome contributions from researchers in all fields of geosciences, applying different analytical methods to the study of worldwide active and fossil sedimentary basins. These methods can include, but are not limited to, structural analyses (both on outcropping and subsurface rocks), thermal maturity assessments, fault dating, geochronological and thermochronological dating, and isotopic analyses on carbonates. Multidisciplinary approaches are greatly welcomed. The aim is to foster discussion on which are the best procedures to better understand the geological processes that drive the tectonic and thermal history of sedimentary basins and their surrounding regions.

Metamorphic minerals provide unique records of the tectonic processes that have shaped Earth through the ages. Innovative new approaches in metamorphic petrology, chemical and isotope micro-analysis, and geochronology provide exciting new avenues to let these minerals tell their story of deformation, reaction and fluid flow. The insights from such research provide key means of testing long-standing concepts in petrology and tectonics, and shifting paradigms in these fields.
This session will highlight integrated metamorphic petrology, with application to tectonics and development of collisional orogens, cratons and subduction zones. We welcome contributions, from petrology, (petro-)chronology, to trace-element and isotope geochemistry. Through these diverse insights, the session will provide an exciting overview of current research on metamorphic and metasomatic processes, as well as the avenues for future innovation.
Fluid-mediated rock transformation, also called mineralogical replacement, are ubiquitous instances of fluid-rock interaction in the crust. With recent developments in measurement techniques, the characterization and understanding of replacement has potential to unravel fluid dynamics and migration pathways, the volume of reactive fluids involved, the deformation associated to the reaction, along with the thermodynamical properties of the reaction. The ambition of the proposed session is to draw a picture of the current state of knowledge about the driving processes of fluid-mediated transformation in the diagenetic domain and in the low metamorphic conditions, with or without associated deformation. We welcome any contribution focusing on methodological, experimental, analytical or nature-related studies of mineralogical replacements and associated phenomenon.

The origin and evolution of the continental lithosphere is closely linked to changes in mantle dynamics through time, from its formation through melt depletion to multistage reworking and reorganisation related to interaction with melts formed both beneath and within it. Understanding this history is critical to constraining terrestrial dynamics, element cycles and metallogeny. We welcome contributions dealing with: (1) Reconstructions of the structure and composition of the lithospheric mantle, and the influence of plumes and subduction zones on root construction; (2) Interactions of plume- and subduction-derived melts and fluids with the continental lithosphere, and the nature and development of metasomatic agents; (3) Source rocks, formation conditions (P-T-fO2) and evolution of mantle melts originating below or in the mantle lithosphere; (4) Deep source regions, melting processes and phase transformation in mantle plumes and their fluids; (5) Modes of melt migration and ascent, as constrained from numerical modelling and microstructures of natural mantle samples; (6) Role of mantle melts and fluids in the generation of hybrid and acid magmas.These topics can be illuminated using the geochemistry and fabric of mantle xenoliths and orogenic peridotites, mantle-derived melts and experimental simulations.

This session is open to all recent works on salt-related tectonics, in various tectonic settings (extensional, contractional, strike-slip or simply gravitational, i.e. passive margins), areas of study (onshore or offshore), and types of approaches (subsurface or outcrop interpretation, seismic imaging and processing, numerical or analogue modelling, and rock-mechanics analysis). Likewise, we welcome contributions at various scales from the relationships between crustal-scale tectonics, evaporite deposition and salt tectonics within sedimentary basins and mountains, to the interaction between salt bodies and their surrounding sediments, to intra-salt deformation. Contributions on shale tectonics are also welcome.
The session will start with the speech of Jean-Paul Callot "The role of salt in mountain building, from minibasin formation to orogen dynamic" (invited speaker).
The session deals with the documentation and modelling of the tectonic, deformation and geodetic features of any type of volcanic area, on Earth and in the Solar System. The focus is on advancing our understanding on any type of deformation of active and non-active volcanoes, on the associated behaviours, and the implications for hazards. We welcome contributions based on results from fieldwork, remote-sensing studies, geodetic and geophysical measurements, analytical, analogue and numerical simulations, and laboratory studies of volcanic rocks.
Studies may be focused at the regional scale, investigating the tectonic setting responsible for and controlling volcanic activity, both along divergent and convergent plate boundaries, as well in intraplate settings. At a more local scale, all types of surface deformation in volcanic areas are of interest, such as elastic inflation and deflation, or anelastic processes, including caldera and flank collapses. Deeper, sub-volcanic deformation studies, concerning the emplacement of intrusions, as sills, dikes and laccoliths, are most welcome.
We also particularly welcome geophysical data aimed at understanding magmatic processes during volcano unrest. These include geodetic studies obtained mainly through GPS and InSAR, as well as at their modelling to imagine sources.
The session includes, but is not restricted to, the following topics:
volcanism and regional tectonics;
formation of magma chambers, laccoliths, and other intrusions;
dyke and sill propagation, emplacement, and arrest;
earthquakes and eruptions;
caldera collapse, resurgence, and unrest;
flank collapse;
volcano deformation monitoring;
volcano deformation and hazard mitigation;
volcano unrest;
mechanical properties of rocks in volcanic areas.
The Fagradalsfjall eruption on the Reykjanes Peninsula of Iceland started on 19 March 2021. It provides a unique opportunity to study all aspects of a low-intensity effusive basaltic eruption in great detail using multidisciplinary approaches. The Fagradalsfjall eruption followed a several-week long period of intense seismicity and deformation associated with formation of the feeding dike. The eruption terminated on September 18, 2021, after producing a lava field covering about 4.5 km2. The eruption progressed through several phases, each characterized by different emission sources, eruptive style, intensities, and associated hazards. The eruption may be representative of the formation of a shield volcano, a process that the scientific community has had limited chances to observe in real time.
We welcome submissions on sustained low-intensity basaltic eruptions including (but not limited to) the 2021 Fagradalsfjall eruption; their plumbling systems, eruptive products, and impacts. We particularly encourage comparative studies across different regions that may help us to better understand the volcanic processes that are active in the Fagradalsfjall eruption.
Topics may include, for example: physical volcanology of eruptive products and eruptive behavior; lava flow modeling; acoustic studies; petrology; geochemistry and interaction with groundwater; studies of volcanic gases; crustal deformation; seismology; volcano monitoring; social effects; health effects; hazard mitigation; tectonic implications; volcano-tectonic interactions; atmosphere-climate interactions, etc.

Gravity and magnetic field data contribute to a wide range of geo-scientific research, from imaging the structure of the earth and geodynamic processes near surface investigations. The first part of this session is dedicated to contributions related to spatial and temporal variations of the Earth gravity and magnetic field at all scales. Contributions to modern potential field research are welcome, including instrumental issues, data processing techniques, machine learning, interpretation methods, innovative applications of the results and data collected by modern satellite missions, potential theory, as well as case histories.
The second part of this session will focus on the practical solution of various formulations of geodetic boundary-value problems to yield precise local and regional high-resolution (quasi)geoid models. Contributions describing recent developments in theory, processing methods, downward continuation of satellite and airborne data, treatment of altimetry and shipborne data, terrain modeling, software development and the combination of gravity data with other signals of the gravity field for a precise local and regional gravity field determination are welcome. Topics such as the comparison of methods and results, the interpretation of residuals as well as geoid applications to satellite altimetry, oceanography, vertical datums and local and regional geospatial height registration are of a special interest.
The last decades have seen unprecedented development of various datasets ranging from zircon provenance studies, igneous and metamorphic petrology, tectonics, geophysics, numerical modelling and paleogeographical reconstructions enabling a more realistic understanding of amalgamation processes related to formation of the most recent supercontinent Pangea. Active discussion is centered on the pre-orogenic evolution and paleogeographic position of large Precambrian crustal segments, as well as the age and number of intervening oceans and their role in building the Variscan Orogenic Belt in Europe, North America and Africa. While, in Central Asia, the Paleozoic formation and mutual interaction of the Kazakhstan, Mongolian and Tarim-North China collages that formed the giant Central Asian Orogenic Belt is discussed. The Variscan Orogeny operated in the heart of Pangea and was controlled by the amalgamation of large continental masses, and the penecontemporaneous Central Asian Orogenic Belt formed at its periphery by accretion of oceanic fragments and some Precambrian blocks. The two contrasting orogens contributed to the formation of a 20,000 km long Late Paleozoic Trans-Euroasian orogen – the largest collisional system on the Earth. It is our aim to bring together the Variscan and Central Asian Orogenic Belt communities to discuss the contrasting collisional and accretionary processes operating along-strike of the Trans-Euroasian orogen from all perspectives of geosciences.

Cratons form the ancient, stable cores of most of the Earth’s continents. Knowledge about the present-day architecture of cratons is the key to understand the evolution of continental plates. In addition to that, cratons concentrate many economically relevant mineral deposits, which are indispensable for a modern society. For many cratonic regions however, little is still known about the present-day lithospheric structure and how it evolved since the Archean, mainly due to their remoteness and harsh local environmental conditions. Ongoing data acquisition, as well as the usage and optimization of
remote and passive techniques have shed new light on the lithospheric architecture of cratonic regions. Recent advancements across several disciplines show that cratons are more varied and fragmented than previously assumed, which has strong implications for geodynamic interactions with the convective mantle and long-term stability.
In this session, we welcome contributions across different scales that describe the cratonic lithosphere and its evolution with time, up to the dawn of plate tectonics. We aim to address topics like: characterization and evolution of cratonic crust and lithosphere; coupling between cratonic crust and mantle; mechanisms to form, maintain and destroy cratonic roots; craton-plume interaction; the role of cratons in supercontinent configurations; connection of cratons to mineral deposits.
We would like to raise discussions within a multidisciplinary session and therefore welcome contributions across a wide range of disciplines, including, but not limited to geodynamics, geology, tectonics, seismology, gravity, geochemistry, petrology, as well as joint approaches.

Lithosphere evolution, reflected in the lithosphere structure, controls the deposition of mineral resources, many of which occur in specific geodynamic settings. We invite contributions from various geophysical, geodynamic, geological, and geochemical studies, as well as from numerical modeling, which address the questions how various plate tectonics and mantle dynamics processes modify the lithosphere structure, control ore deposits, and how these processes changed during the Earth's evolution. We particularly invite contributions with focus on regional geophysical studies of the crust and upper mantle.
This session is a part of the International Lithosphere Program Task Force 1. We invite contributions from everyone interested in the topic and invite them to join the ILP TF1.

This 105-minute short course aims to introduce non-geologists to structural and petrological geological principles, which are used by geologists to understand system earth.
The data available to geologists is often minimal, incomplete and representative for only part of the geological history. Besides learning field techniques to acquire and measure data, geologists need to develop a logical way of thinking to close gaps in the data to understand the system. There is a difference in the reality observed from field observation and the final geological model that tells the story.
In this course we briefly introduce the following subjects:
1) Grounding rocks: Introduction to the principles of geology.
2) Collecting rocks: The how, what, and pitfalls of field data acquisition.
3) Failing rocks: From structural field data to (paleo-)stress analysis.
4) Dating rocks: Absolute and relative dating of rocks using petrology and geochronology methods.
5) Shaping rocks: The morphology of landscapes as tectonic constraints
6) Crossing rocks over: How geology benefits from seismology, geodynamic and geodesy research, and vice-versa.
7) Q&A!
Our aim is not to make you the next specialist in geology, but we would rather try and make you aware of the challenges a geologist faces when they go out into the field. Additionally, the quality of data and the methods used nowadays are addressed to give other earth scientists a feel for the capabilities and limits of geological research. This course is given by Early Career Scientist geologists and geoscientists and forms a quartet with the short courses on ‘Geodynamics 101 (A&B)’, ‘Seismology 101’, and ‘Geodesy 101’. For this reason, we will also explain what kind of information we expect from the fields of seismology, geodynamics and geodesy, and we hope to receive some feedback in what kind of information you could use from our side.

The main goal of this short course is to provide an introduction into the basic concepts of numerical modelling of solid Earth processes in the Earth’s crust and mantle in a non-technical manner. We discuss the building blocks of a numerical code and how to set up a model to study geodynamic problems. Emphasis is put on best practices and their implementations including code verification, model validation, internal consistency checks, and software and data management.
The short course introduces the following topics:
(1) The physical model, including the conservation and constitutive equations
(2) The numerical model, including numerical methods, discretisation, and kinematical descriptions
(3) Code verification, including benchmarking
(4) Model design, including modelling philosophies
(5) Model validation and subsequent analysis
(6) Communication of modelling results and effective software, data, and resource management
Armed with the knowledge of a typical numerical modelling workflow, participants will be better able to critically assess geodynamic numerical modelling papers and know how to start with numerical modelling.
This short course is run by early career geodynamicists. It is aimed at everyone who is interested in, but not necessarily experienced with, geodynamic numerical models; in particular early career scientists (BSc, MSc, PhD students and postdocs) and people who are new to the field of geodynamic modelling.

What is the “Potsdam Gravity Potato”? What is a reference frame and why is it necessary to know in which reference frame GNSS velocities are provided? Geodetic data, like GNSS data or gravity data, are used in many geoscientific disciplines, such as hydrology, glaciology, geodynamics, oceanography and seismology. This course aims to give an introduction into geodetic datasets and presents what is necessary to consider when using such data. This 105-minute short course is part of the quartet of introductory 101 courses on Geodynamics 101, Geology 101 and Seismology 101.
The short course Geodesy 101 will introduce basic geodetic concepts within the areas of GNSS and gravity data analysis. In particular, we will talk about:
- GNSS data analysis
- Reference frames
- Gravity data analysis
We will also show short examples of data handling and processing using open-source software tools. Participants are not required to bring a laptop or have any previous knowledge of geodetic data analysis.
Our aim is to give you more background information on what geodetic data can tell us and what not. You won’t be a Geodesist by the end of the short course, but we hope that you are able to have gained more knowledge about the limitations as well as advantages of geodetic data. The course is run by early career scientists from the Geodesy division, and is aimed for all attendees (ECS and non-ECS) from all divisions who are using geodetic data frequently or are just interested to know what geodesists work on on a daily basis. We hope to have a lively discussion during the short course and we are also looking forward to feedback by non-geodesists on what they need to know when they use geodetic data.
