The European Green Deal, first announced in December 2019, sets ambitious targets, including reaching climate neutrality in Europe by 2050; addressing the drivers of biodiversity loss in Europe; restoring degraded ecosystems; and adopting a zero-pollution action plan for air, water and soils. Achieving these bold targets will require scientific expertise from many different geoscience areas.

This Union Symposium will provide participants with an introduction to the European Green Deal, highlighting aspects that require geoscience expertise and discussing how scientists can engage with, and effectively support, the Deal’s ambitious targets. The session will also discuss the different stages of development and implementation of the Green Deal’s targets, what’s coming next and where science can be integrated. As a European scientific union focusing on many aspects relating to the Green Deal, the EGU is well positioned to highlight these areas through this session and beyond.

The panel will include scientists working in areas related to the Green Deal and policymakers who either initially proposed the Green Deal roadmap or who are currently working on its implementation. The session will include presentations from these speakers as well as a moderated discussion on how geoscientists can best support the Green Deal’s targets and a Q&A with the audience. Despite being a European specific initiative, the Green Deal also outlines missions working with neighbouring countries to the EU and some countries in Africa. In addition, many countries outside of the EU have discussed similar strategies. This session will therefore be of interest to a broader international audience.

The Covid-19 pandemic has been a major trauma for humanity and naturally calls for multiple scientifically-based responses to mitigate the risks and build resilience to it and its potential successors. It should be stressed that the geosciences communities have already strived to respond to it, drawing on their expertise, even if they have also had to face various upheavals as a result of the pandemic.
The solicited talks of this Union Session will highlight these contributions but, more importantly, will seek to identify new developments. These include a better understanding of zoonotic spillovers, anomalous mechanisms and pathways of multi-scale transmission, the role of natural and man-made environmental complexity.
These developments are expected to greatly improve monitoring and governance of the epidemic at different scales and strengthen community engagement. Overall, they put geosciences into a post-Covid perspective.

In 2020, humanity faced up to an urgent and deadly challenge. The COVID-19 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spread rapidly and with shocking impacts, tragically claiming (at the time of writing) hundreds of thousands of lives.

Rapid and dramatic action was called for and – thankfully – was largely forthcoming, from governments, businesses and individuals.

Across the globe, drastic lifestyle changes were imposed, with freedoms curtailed and life for many stripped back to the necessities, and yet these changes were generally accepted. Welcomed even. They were to keep us safe. To protect us now and into the future.

The contrast with the Climate Emergency is fascinating. It too is an urgent and deadly existential challenge, and yet the consensus is that actions are too little, too slow, the urgency is lacking, the public buy-in largely absent.

Despite growing awareness over many decades, there is no effective, concerted programme to address this largest of all global problems.

It appears likely that any reduction in carbon emissions as a result of lifestyle changes to contain the spread of the Coronavirus will be only temporary. Furthermore, financial initiatives to help economies restart and other initiatives to prevent the spread of the disease, such as reduced use of public transport and a huge escalation in the use of single use plastics, are likely to bring increased environmental harm.

This Union session looks at the Climate and Ecological Emergency through the lens of the COVID-19 crisis, and asks, what lessons can we learn? How can some of that urgency be brought to this greatest existential challenge? Can lifestyle changes implemented during the crisis which bring positive outcomes for our future sustainability be maintained and enhanced? And can those which are increasing harm be turned around? In short, can this terrible global crisis serve as a wakeup call for action to protect all our futures?

This Union Symposium invites a broad range of thinkers and influencers, ranging from leading climate scientists to broadcasters, policymakers and influencers to provide their perspectives on how the COVID-19 crisis can help inform actions to address our generation’s greatest challenge.

As geoscientists, we watch over the health of our planet, we see the changes, we understand the impacts. We know the likely consequences of inaction. Our community has a vital role to play.

The terrestrial biosphere exerts disproportionate influence on Earth's climate, making improvements in its representation key to reducing climate uncertainty. After 50 years of development, land surface models contain detailed processes of energy fluxes, photosynthesis, hydrology, C-N-P cycles, and land-use within coarse non-interacting grid cells. Remaining discrepancies in fidelity to observed carbon and water cycles appear primarily related to deficiencies in the representation of forests and human activity. These include the omission of spatial processes of disturbance, migration, adaptation, and management. Also missing is the generative process of life, evolution, which gives rise to life history strategies, trophic-metabolic networks, leaf economics, local adaptation (i.e., optimality, acclimation), and plant behaviour. Despite improvements in representing vegetation demography by utilizing emergent properties of allometric scaling, canopy geometric realism remains low. This may bias carbon and water cycles per radiative transfer and coupled processes of photosynthesis, regeneration, evapotranspiration, heterotrophic respiration, and disturbance.

We believe that physics-based botanical models, forest landscape models, and terrestrial biosphere models may soon merge into new multi-scale models. While low-dimensional representations of forests are often used to improve computational efficiency and cope with a dearth of 4-D forest observatories, deep learning may be combined with new autonomous scanning systems - proximal and/or remote - such as our proposed global tower-based '5DNet' to infer evolvable 4-D physics-based models. This includes learning multi-generation tree models with 4-D traits from image and/or laser scanning time-series. To date, 4-D ontogeny has been inferred from individual scans of mature trees, multi-plant phenological events have been tracked in real-time, and the self-similar and -organizing nature of plants has been used to efficiently compress tree models down to their generating parameters. Achieving leaf-to-global scaling may require co-processor acceleration and fusing deep learning with 3-D radiative transfer modeling to infer global surface properties. An additional focus on evolution and human activity comes as 21st century land surface models mature into general simulations of life on Earth.

This Union Symposium presents exciting work toward achieving this moonshot in Earth observation and systems modeling.

Patience Cowie revolutionised our understanding of the growth and interaction of faults, and the impact these have on the topography of extensional settings. Through her tenacious focus on the science, infectious enthusiasm, wonderful sense of humour and commitment to women in science, she inspired a generation of young researchers, many of whom are presenting in this Union Symposium.
Patience’s early research began with the growth and interaction of faults and their length/displacement scaling. She studied faults at different scales, from small scale, linking damage zone to displacement, to whole fault systems, demonstrating how the development of complex fault networks impacts fault slip rate. She built numerical models of fault interactions that integrated the response of river systems to the changing topography. The predictions of these models challenged geomorphological and stratigraphic understanding of extensional settings, and resulted in a wealth of research on the extraction of tectonic signals from river profiles, and the sedimentological record of these processes.
This Union Symposium aims to sustain the momentum of Patience Cowie’s multidisciplinary approach to tackling fundamental questions concerning the interactions between the brittle upper crust and the surface processes that govern much of Earth’s topography. We are now addressing the physical mechanisms that can lead to the variety of slip styles and frictional behaviour on faults; this is critical to forecasting seismic hazard. As faults propagate, they determine the geometry of river networks, the distribution of erosion and the response time of river channels. These interactions govern sediment routing systems and the stratigraphic record of these processes. This symposium seeks to explore a future vision for the science underpinned by the fundamental processes linking faults and topography, balanced by an awareness of the societal challenges of risk management to natural hazards in these settings.

GDB – Great Debates

Programme group chairs: Peter van der Beek, Chloe Hill

GDB1

Different forms of systemic discrimination are experienced by underrepresented minorities throughout society, and the geoscience community is not immune to this often overlooked or unrecognised problem. Recent events and research have highlighted the systematic problem of racism in geoscience, but even beyond race-based discrimination many geoscientists experience some form of discrimination on a daily basis both within their professional and personal life.
EGU has made a commitment to highlighting these challenges, and are seeking to improve our efforts to make discrimination unacceptable, especially within the geoscience community. Through a series of actions including blogs, publications and public events, EGU will continue to work to raise awareness of discrimination in all its forms.
This Great Debate will build on EGU’s stated ambition to promote equality, inclusivity and diversity in geoscience at all levels, and draw influence from how discrimination in the geosciences is experienced by our members from a personal perspective. This panel discussion aims to raise awareness of these issues and try to understand what concrete actions EGU and other scientific societies can take to effect real change for everyone affected by some form of discrimination.

At the beginning of the General Assembly 2020 EGU has published a declaration on the significance of geoscience expertise to meet global societal challenges. At the same time, a global public health crisis was happening due to COVID-19. During any public crisis including this public health crisis or any emerging environmental crisis, authorities often seek advice from experts to take the best possible actions. In many countries systems are in place for several potential environmental disasters such as floods and storms. However, for less frequent or new issues there is no established protocol. As sometimes fast reaction is key to save lives, experts may find themselves in the situation that a statement has to be issued under strong time constraints and without peer-review. In this great debate we would like to discuss different aspects of the requirement for fast information and how to address it, especially how to deal with the related lack of quality assessments and uncertainties. We will also discuss how this COVID-19 public health crisis could draw on the experience gained during other disasters that happen more frequently and which lessons we can learn from that.

Conducting geoscientific research today is unthinkable without research software. However, there are different views on the importance of research software and its role in science.

The proposals to improve research software touch on all aspects of academia, such as funding, credit and reward systems, job descriptions and career paths, or evaluation schemes (of papers, people, projects). A growing community of researchers and software developers gather under the umbrella of Research Software Engineering (RSEng) and argue that research software is not merely a by-product of science, but effective and sustainable development of research software needs a skillset and resources beyond current academic education or management plans.

This great debate puts the questions, problems, challenges, and opportunities around research software in geosciences to the center of EGU, as it is a topic that concerns every researcher who uses computers. It features short opening statements by a panel representing the full breadth of stakeholders in science, and continues with a discussion on how to improve the situation for EGU members who work with and on research software:

- Does research software get the attention it deserves in Geosciences?
- How can we better support research software in Geosciences? How does it differ from other tools/equipment we use?
- Does a lack of support for research software lead to bad science in Geosciences?
- What failures can we learn from where research software played a critical role?
- How can (and should?) research software become a first class output across all Geosciences? How can credit be given to it’s authors and contributors?
- What skills and mindset set people who identify as research software engineers apart from “regular researchers”?
- How should the education of researchers include research software?
- What makes research software in Geosciences “good”, “FAIR”, useful, or user friendly? Who is responsible for that?
- What tasks can individual researchers or leaders in scientific communities undertake if they want to positively influence research software?
- Research software and open source - how do these meet? How can communities be built and can they mitigate issues around research software?

"Publish or perish" is the motto for Fast Science. All Early Career Scientists (ECS) are well aware that the scientific landscape has become a publication factory. Fast Science prefers quantity over quality, thereby creating a proliferation of articles that overwhelm readers and publishers and threaten the effectiveness of the peer-review system. The widespread three-year turnover of project grants causes a lack of longer-term, comprehensively monitored data-sets, contributing to incremental, not fundamental, discoveries. Researchers are challenged to publish at a high frequency, gain international experience, receive outstanding teaching evaluations and acquire multiple scholarships and grants, all of which has to be balanced with their private life. It is no surprise that the 2019 ECS debate addressed mental health problems. In contrast, the Slow Science Movement (http://slow-science.org/) believes that science should be a slow, steady, methodical process and that scientists should not be expected to provide "quick solutions" to society's problems. Slow Science supports curious scientific research and opposes performance targets.

During this Great Debate, we will discuss the alternatives to Fast Science. Is Slow Science a realistic movement? What can we learn from it and what are the disadvantages compared to Fast Science? Would it be possible to integrate this concept of Slow Science into the current scientific landscape and create more sustainable science? Should we aim to publish coherent stories instead of splitting them up, thereby focusing on the real knowledge gain and scientific advances?

The attendees will share their opinions in small groups discussing one of the following topics, each revolving around the themes raised above. After the group-internal discussion phase, the main points from each group will be shared among the groups to continue further discussion and debate.

Being bullied or harassed at your workspace has a tremendous impact on both the professional and the personal wellbeing of the person subjected to such treatment.
Which acts and behaviours classify as bullying and harassment? How can you recognize if you or a co-worker/friend are the target of bullying and harassment? How can you protect yourself and others from bullying and harassment? What can we all together do to stop harmful behaviours from individuals or overarching structures? What do institutions need to do in order to create a healthy and safe work environment?

These questions and more will be addressed during this ECS Great Debate, which shall raise awareness for the harmful effects of bullying and harassment in academia, provide clarity around this complex matter, and encourage people to speak up and take action against it. Through round-table discussions we will talk about what is needed to create a healthy, safe and inclusive work environment for everyone, where bullying, any form of harassment and intimidation have no place.

The European Geosciences Union is a the largest Geoscientific Union in Europe, largely run by volunteers. Perhaps you have been to the General Assembly before, maybe you have published in one of the EGU journals, or are you following EGU and/or several EGU divisions on social media.

Whatever your closest link with EGU, would you like to get involved?

This short course is aimed at Early Career Scientists and will provide an overview of all the activities of EGU, which are much more than just the General Assembly. We will give practical tips on how to get involved, who to contact and where to find specific information if you want to organise a event.

More than 50% of EGU's members consist of ECS, let's get active!

Recent publications show that many people working in academia experience mental health issues. Factors like job insecurity, limited amount of time and poor management 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 2019-2020, 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 invite panelists to share their experiences, how they dealt with it and what support they received. 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.

Public information:
We kindly invite you to participate to the Short Course in which our two speakers will present their talks about “Mental Health in Academia: Unmet Needs and Self-Assessment" by Jessica Carrasco and
“Being a more mindful scientist” by Maria Scheel

SC2 – Career development

Programme group scientific officers: Michael Dietze, Anouk Beniest

SC2.1

COVID-19 has affected our daily lives in an unprecedented range of ways. It is a human, economic and social crisis that has potentially changed the way we live, work and interact with each other forever. Researchers have not been spared from this, facing numerous challenges since the start of the outbreak, both personal and professional. This session will focus on a couple of these challenges in detail and discuss the lessons that we can learn to strengthen the scientific community and research in the future.

The first challenge that this session will address is the impact COVID-19 has had on research activities directly. Since the introduction of lockdowns in Europe, many researchers have had to reduce their research activities due to additional responsibilities at home while others have been locked out of laboratories and libraries, of all kinds, or been unable to undertake fieldwork to collect primary data. This has not only impacted the careers of many scientists but also led to project goals becoming unachievable, issues with funding and PhD candidates unable to complete their research. In this short course we will look at what can be done on an individual level to improve the current situation that many researchers find themselves in.

In addition to the financial, structural difficulties, many researchers are starting to view the way that they do science as more flexible than they might have considered possible before the coronavirus outbreak. This short course will also make space for discussions about how the practicalities of doing research (be it infrastructure, work patterns or styles of employment) could change in the light of what we have learned during this challenging time. We will also ask the question ‘how can large organisations and institutions attempt to better prepare in case another global crisis arises in the future?’

Drafting your first grant proposal can be daunting. Grant writing improves with experience, so how do early career scientists compete on equal footing with those who are more established? In this short course, a panel of scientists and funding agencies will share their experience on applying to different funding bodies and provide top tips to early career scientists. You can gain insight and (even better) inspiration by discussing with the panel the bits and pieces you may struggle with when writing a strong grant proposal. This session will be followed by a ‘pop-up’ session in the Networking and ECS lounge, for more specific questions to our panel.
NOTE - this course has a broader scope than the more specific ERC and Marie Curie short courses. This course gives broad tips and hints on how to write a successful proposal irrespective of the funding body.

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.

Diversity has many dimensions including, but not limited to, race/ethnicity, gender, disability status, nationality, language, religious affiliation, sexual orientation, and socioeconomic background. Diversity is key for scientific progress and society because different perspectives and life experiences give rise to diversity in scientific questions and approaches to address them, and stimulate collaboration between academics and local communities. Nevertheless, geosciences remain the least diverse of all STEM (science, technology, engineering and mathematics) fields.
In this short course, early career scientists will be presented with practical advice on how they can contribute to promoting diversity in both their present and future career stages and help to build a geoscience community that is welcoming and supporting to marginalized scientists.

The short course will consist of the following invited talks, followed by discussion with the speakers:

(1) Asmeret Asefaw Berhe: "Forms of diversity and how can early career scientists support it"

(2) Bala Chaudhary: "Building an anti-racist lab"

(3) Budiman Minasny: "The fair-play of scientific collaborations - beyond helicopter research"

Scientists of all career stages are welcome to participate and join the discussions!

Bullying and discrimination within academia are widespread and impact science at all levels. Early Career Scientists of underprivileged and underrepresented groups are those most affected by such work environments. Thus, discriminatory work environments further contribute to the continued lack of diversity within the geosciences, ultimately hampering scientific advancement. Systemic power dynamics within academia lead to the fear of retaliation and the impunity of professors, which is why culprits get away with abuse far too often. Despite increased discussions about this topic, institutions tend to provide little or ineffective support for those affected, nor clear steps forward. In this interactive short course, an expert panel will (i) provide practical recommendations on how to combat discriminatory work environments and (ii) explain strategies for bystander intervention. This will be followed by an open discussion between the expert panel and all participants about how to battle discriminatory work environments in the geosciences.
This Short Course is a joint effort of the Equality, Diversity and Inclusion Working Group of EGU, the Young Hydrologic Society and EGU.
With Prof. Dr. Aradhna E. Tripati, Prof. Dr. Erika Marin-Spiotta, Dr. Anjana Khatwa and Dr. Moses Milazzo we have a great panel consisting of a diverse group of experts and ambassadors for more diversity and equity within the geosciences.

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 Todd A. Ehlers, who is an all-round geologist, head of the Earth Surface Dynamics group at the University of Tuebingen, Germany. Todd’s work has been contributing to better understand how tectonic, climatic and biogenic forces interact and drive landscape evolution, using an ensemble of techniques such as thermochronology, cosmogenic nuclides, numerical modelling, near-surface geophysics. Besides his research expertise, we shall engage in conversations regarding the challenges that came his way, and the manner in which he overcame those, and how his research shaped his life and in turn, how his life is impacted by the research he 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 Todd shall be happy to answer.

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 gives 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. The audience is invited to propose specific topics and/or questions for discussion in advance to ecs-st@egu.eu.

How do you peer-review? Apparently you are just supposed to miraculously know. Many of us never receive formal training in peer review, yet our peer-reviews are the cornerstone of scientific legitimacy. Constructive, respectful, coherent reviews nurture dialogue and advance research. So, how can we review papers in an efficient way? In this course, we suggest a process to help ensure that we give the authors the most useful feedback? We will hear from peer-review experts about how they go about the process and have an open discussion with the audience.

Publishing your research in a peer reviewed journal is essential for a career in research. The EGU Journals are fully open access which is great, but the open discussion 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. An open discussion will be served to give you time for questions to the editors,and for them to suggest some ‘top tips’ for a 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.

The short course aims to present the current status of the training and education in raw materials in the world, the evolution of skills and competences in the raw materials sector and show to attendants the free online educational platform developed by the INTERMIN Team. Users will be guided through the diverse facilities of the portal such as a searchable wiki of training centres database interlinked with a geographic information system of the available raw materials training programmes at a global scale. This facility shall be organised by the user based on the interesting skill to be acquired with the different training programmes.
The platform is a tool to help career guidance and lifelong learning within the raw materials community. It encompasses details of the database of training programmes, its strengths, weaknesses, protagonists, languages, content in relation to other courses, number of participants, target audience, duration & workload, and nature of classes. The platform facilitates discussions to support career guidance with the aim of enhancing collaboration between students, career guidance services, employers, education and training institutions, and NGOs. The portal and its network are thus expected to pave the way for establishing common training programmes in the raw materials sectors.
The International Network of Raw Materials Training Centres (INTERMIN) involves a network that represents more than 550 000 geoscientists working in academic research, industry, governments, and NGOs in 5 continents. The network develops synergies and international cooperation with the relevant EU Member States and the leading counterparts in third countries, based on specific country expertise in the primary and secondary raw materials sectors. The network has mapped skills and knowledge in the EU and the third countries, identified key knowledge gaps and emerging needs, developed a roadmap for improving skills and knowledge, as well as established common training programmes in the raw materials sectors.


INTERMIN project has received funding from the EU Horizon2020 research and innovation programme under Grant Agreement No 776642

SC3 – Science communication

Programme group scientific officers: Michael Dietze, Anouk Beniest

SC3.1

Preparation and presentation of research findings at conferences are an important and time-consuming part of a scientist’s life. From a scientific perspective, the lack of time and orientation on how to create the poster one would like to present, can be very dissatisfying. Similar sensations are coming up while attending poster sessions at a conference: often, it’s just being overwhelmed by the amount of information presented in a non-reader-friendly way. Although a properly designed poster gains more attention, is easier to understand and can therefore improve visibility and the chances of having interesting discussions about one’s research, it is still difficult to achieve a well-designed poster. Why is this still the case in times where we can easily look up the Do’s and Don’ts of poster design online?
One reason is that there is more to professional graphic and information design than choosing the right font size or deciding upon the best color combination. Therefore, in this short course we will take a step back and have a look on how professional designers are planning their projects, starting their workflow and how this can help a scientist to design a poster for a conference effectively and properly. The design thinking process consists of a phase of emphasizing, defining the problem, ideating, creating a prototype, testing - and most important: improving again. Implementing this process helps to develop a detailed plan, which can give guidelines and structure when designing posters.
We will go through the design process theoretically and then discuss the different questions together addressing the scientific poster. 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. Furthermore, it will be useful to bring something to note your thoughts during the course to create your own cheat-sheet to which you can come back to when starting the work on your next poster.

The work of scientists does not end with publishing their results in peer-reviewed journals and presenting them at specialized conferences. One side of the work that is becoming more and more relevant and often is required by funding agencies to be specified in one’s project proposal is outreach. What does outreach mean? Very simply, it means to engage with the non-scientific public and a wider audience than you are commonly used to. There are many ways to do outreach, from blogging and vlogging, using social media, write for a science dissemination journal, participate as a speaker to local science festivals, organize open-days in the laboratory and so on.
With this short course, we aim at giving you some practical examples of different outreach activities and tips and suggestions from personal and peers experiences. In the last part of the course, you will work singularly to come up with an outreach idea based on your research activity. You may use it on your next proposal, you never know!

“Science isn't finished until it's communicated. The communication to wider audiences is part of the job of being a scientist, and so how you communicate is absolutely vital.” - Professor Sir Mark Walport, Chief Scientific Advisor to the UK government

Science is vital to society. It allows civilisations to advance, economies to prosper and provides solutions to societal problems. Unfortunately, the benefits of science aren’t automatically understood by the wider public – they must be communicated!

Communicating your science to a broader audience can also be hugely beneficial on a personal level – potentially boosting you profile as an expert, connecting you with new research and/or industry partners, and sparking ideas for new areas of research. Communicating your research to citizens is obviously important but how to communicate effectively to a non-scientific community isn’t always so straightforward. The first half of this session will outline some tips to communicate your research with the public, the challenges that scientists may face and how these can be overcome.

The second half of the session will feature speakers who are working to bridge the gap between research and society. They will outline some institutionalised routes that scientists can take to connect with citizens and provide examples of when it has had unexpected benefits.

Science and policy often feel like two different worlds, working on different timescales and using different languages. Despite this, almost every policy decision has a scientific component to it. And while science alone will never make policy, it can allow policymakers to more accurately assess the benefits and potential consequences of different policy pathways.

This session will highlight some of the key messages from the European Commission Joint Research Centre's recently published ‘Science for Policy Handbook’ (https://egu.eu/0HNFV9/). It will be hosted by two of the Handbooks key authors, Marta Sienkiewicz and Lene Topp.
Some of the key topics that will be outlined include:

- The importance of strategic planning for engaging relevant policymakers
- The different policy actors and their role in the policymaking process
- Examples of how you can speak the language that policymakers understand and pay attention to
- Finding windows of opportunity and building relationships

Attendees will also be given the opportunity to ask any questions they have about the Handbook or working at the science for policy interface more generally. This session is open to all EGU scientific divisions and scientists at all stages of their careers.

The Joint Research Centre’s Science for Policy Handbook is available free online and will give you a sneak peek into some of this session’s content! https://egu.eu/0HNFV9/

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. Researchers will learn about how parliaments use evidence in their policy-shaping processes and the mechanisms that feed science advice into Parliament. This session will be hosted by individuals who work at the interface of science and policy, drawing from real-life examples and providing plenty of opportunities for attendees to ask questions.

SC4 – Scientific approaches & concepts

Programme group scientific officers: Michael Dietze, Anouk Beniest

SC4.1

This 60-minute short course aims to introduce non-geologists to structural and petrological geological principles, which are used by geologist 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) Geology rocks: Introduction to the principles of geology and field data acquisition
2) Failing rocks: From structural field data to (paleo-)stress analysis
3) Dating rocks: Absolute and relative dating of rocks using petrology and geochronology methods
4) Crossover rocks: How geology benefits from seismology and geodynamic research and vice-versa

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 seismologists and geodynamicists a feel for the capabilities and limits of geological research. This course is given by Early Career Scientist geologists and geoscientists and forms a trilogy with the short course on ‘Geodynamics 101 (A&B)’ and ‘Seismology 101’. For this reason, we will also explain what kind of information we expect from the fields of seismology and geodynamics 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 a simple geodynamic problem. Emphasis is put on what numerical models are and how they work while taking into account the advantages and limitations of the different methods.

We go through the following topics:
(1) The basic equations used in geodynamic modelling studies, what they mean, and their assumptions
(2) A brief introduction to the various numerical methods
(3) The importance of benchmarking a code
(4) How to go from a geological problem to the model setup
(5) How to set initial and boundary conditions
(6) How to interpret the model results
We will use a simple example from the code ASPECT (https://aspect.geodynamics.org) to illustrate points 4-6 through an in-class demonstration. Participants are not required to bring a laptop or have any previous knowledge of geodynamic numerical modelling.

Armed with the knowledge of a typical numerical modelling workflow, participants will be better able to critically assess geodynamic numerical modelling papers and they will learn how to start with numerical modelling.

This short course is run by early career geodynamicists. It is dedicated to 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.

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 be complementary to 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 (A & B)’ and ‘Geology 101’ to better illustrate the link between these fields.

In ‘Seismology 101’, we will present an introduction to 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 -- in particular early-career scientists. An overview will be given on various methods and processing techniques, which are 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 for 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 rather like to make you aware of how seismology can help you in geoscience. The intention is to discuss each topic in a non-technical manner, emphasizing their strengths and potential shortcomings. This course will help non-seismologists to better understand seismic results and can 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.

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 as the concept of Geoethics. Geoethics is the research and reflection on the values which underpin appropriate behaviors and practices, wherever human activities interact with the Earth system. Geoethics provides a framework from which to define ethical professional behaviors in both geosciences and engineering, and to determine how these should be put into practice for the benefit of society and environment. The Short Course goes is directed towards introducing and training geoscientists in those new concept and ideas as well as exposing the perspectives of this field.

Course Content: (generic until we know the lecturers attending EGU2021 then, adjusted):
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. Geoethics in geoscience communication
7. Recent developments in geoethical thinking
8. Perspectives of Geoethics
9. Geoethics’ case studies: Paleontology, Water Management, Ocean Governance, etc.

Learning objectives

Most often observations and measurements of geophysical systems and dynamical phenomena are obtained as time series whose dynamics usually manifests a nonlinear behavior. During the past decades, nonlinear approaches in geosciences have rapidly developed to gain novel insights on fluid dynamics, greatly improving weather forecasting, on turbulence and stochastic behaviors, on the development of chaos in dynamical systems, and on concepts of networks, nowadays frequently employed in climate research.

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 solar-terrestrial relations. 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.

Why to wait hours for computations to complete, when it could take only a few seconds? Tired of prototyping code in an interactive, high-level language like MATLAB, R or Python and rewriting it in a lower-level language such as C, C++ or Fortran to get high-performance code? Or simply curious about how GPUs and supercomputing are game changers in geosciences?

This short course covers trendy areas in modern geocomputing with broad geoscientific applications. The physical processes governing natural systems' evolution are often mathematically described as systems of differential equations. A performant numerical implementation of the solving algorithm leveraging modern hardware is key and permits to tackle problems that were technically not possible a decade ago.

The goal of this short course is to offer an interactive and tutorial-like hands-on to solve systems of differential equations in parallel on GPUs using the Julia language. Julia combines high-level language simplicity and low-level language performance. The resulting codes and applications are fast, short and readable. We will design and implement a numerical algorithm that predicts ice flow dynamics over mountainous topography using a high-performance computing approach.

The course format is online. You will work on (remote) notebooks to enable best participant experience. The course consists of 2 parts:
1. You will learn about the Julia language, parallel and distributed computing and iterative solvers.
2. You will implement a PDE solver to predict ice flow dynamics on real topography.

By the end of this short course, you will:
- Have a GPU PDE solver that predicts ice-flow;
- Have a Julia code that achieves similar performance than legacy codes (C, CUDA, MPI);
- Know how the Julia language solves the "two-language problem";
- Be able to leverage the computing power of modern GPU accelerated servers and supercomputers;
- Know about the rapidly growing and exciting Julia ecosystem and community.

We look forward to having you on board and will make sure to foster exchange of ideas and knowledge to provide an as inclusive as possible event.

Computer models are essential tools in the earth system sciences. They underpin our search for understanding the earth system functioning and support decision-making across spatial and temporal scales. Predictions of computer models though are conditional on a range of assumptions and input data that are often largely uncertain due to, among others, our limited understanding of earth systems processes and interactions, the simplified representation of spatial heterogeneity in our models, and errors and gaps in the data. To understand the implications of uncertainty and environmental variability on the identification and use of earth system models, we can rely on increasingly powerful Uncertainty and Sensitivity Analysis methods.
In this short course we will:

1) use a set of literature examples to demonstrate the benefits of using Uncertainty and Sensitivity Analysis to support the calibration, evaluation, and simplification of earth systems models and their use to inform decision-making
2) discuss some of the key methodological choices in the set-up of Uncertainty and Sensitivity Analysis and provide guidelines and best-practice examples on how to make such choices
The course will focus on Monte-Carlo methods for uncertainty propagation and Global Sensitivity Analysis (GSA) techniques, such as those discussed in (1) and (2). The course is intended for researchers and practitioners who already have experience of using these techniques as well as beginners.
For those who wants to get some hands-on understanding of GSA before and/or after the course, we have prepared some online tutorials in the form of interactive Jupyter Notebooks (these can be run from browser, no need to install any software):

Uncertainty Analysis - using fully- and extra-probabilistic approaches

Uncertainty analysis is an unavoidable task of risk assessments either for natural hazards like landslides, earthquakes, floods, volcanoes, etc., or for environmental issues like groundwater or soil contamination. When dealing with uncertainties, two categories should be considered as outlined by several authors:
1) “aleatoric uncertainty” (also named “randomness” or “intrinsic variability”) and arises from the natural variability owing to either heterogeneity or to the random character of natural processes (i.e. stochasticity). A common example of aleatoric uncertainty is the variability in weather.
2) “epistemic uncertainty” and arises when dealing with “partial ignorance” i.e. when facing “vague, incomplete or imprecise information” such as limited databases and observations or “imperfect” modelling.

Although the probabilistic setting has been used in a broad range of different applications, the use of probabilities as a tool to represent epistemic uncertainties has often been criticized in situations where the available data are imprecise, scarce, incomplete, vague, qualitative, etc. In such highly uncertain situations, the challenge is to formulate appropriate mathematical tools and models in a quantitative manner, on the one hand, accounting for all data and pieces of information, but, on the other hand, without introducing unwarranted assumptions. Therefore, to overcome the shortcomings of the pure probabilistic setting, several alternative representation methods have been developed: probability boxes, possibility distributions, Dempster-Shafer structures, etc.

The purpose of the short course is to describe how these new tools can be used to handle epistemic uncertainty for the different stages:
- Uncertainty representation;
- Propagation;
- Sensitivity analysis;
- Support for decision-making.

Comparisons with fully probabilistic approaches will also be performed. The short course will be supported by real cases taken from risk assessment studies for earthquakes (Rohmer & Baudrit, Nat. Haz., 2011), sea level rise (Le Cozannet et al., ERL, 2017), and groundwater contamination (Baudrit et al., J. Cont. Hydrology, 2007). These illustrations will be performed using R package “HYRISK” (https://cran.r-project.org/web/packages/HYRISK/index.html).

Numerical models used for weather and climate prediction have traditionally been formulated in a deterministic manner. In other words, given a particular state of the resolved scale variables, the most likely forcing from sub-grid scale motions and parametrised processes is estimated and used to predict the evolution of the large-scale flow. However, knowledge uncertainties, necessary simplifications in representing the physical processes in numerical models, and the lack of scale-separation in the Earth System mean that this approach is a large source of error in forecasts. Over recent years, an alternative paradigm has developed: the use of stochastic techniques to represent the effects of uncertain small-scale and parametrised processes. Instead of predicting the most likely forcing effect of these processes on the resolved scales, a Monte-Carlo approach is used. Integrations of the numerical model sample possible realisations of the forcing.

Stochastic parametrisations are now the norm in ensemble weather and seasonal forecasts worldwide. By accounting for uncertainty in the forecast due to the limitations of numerical models, stochastic parametrisations improve the reliability of ensemble forecasts. We are now seeing their adaptation for use in climate models, with stochastic parametrisations being developed to represent a wide range of processes in the Earth System, including processes in the atmosphere, oceans, and land surface.

This course will introduce the art and science of stochastic parametrisation, including

> Purpose: model uncertainty, ensemble forecasting, climate applications
> Foundations: stochastic processes
> Theory: how to design a stochastic scheme
> Realisation: the path from a well-designed scheme to an operational implementation in a numerical model

This course is aimed at PhD students, Early Career Scientists, and all those interested in an overview of key concepts in stochastic parametrisation. The course will be taught through a combination of presentations and interactive exercises using python notebooks. No prior knowledge of python is necessary.

Public information:
Due to the reduced length of time allocated to each short course this year, the short course will consist of presentations and Q&A, and will no longer include python exercises.

In order to be able to have predictive power on extreme events we need to rely on mathematical approaches that provide us with some degree of universality, so that we have rigorous ways to extrapolate information beyond what has been already recorded. In this short course we will introduce frameworks based on dynamical systems theory and statistical mechanics that allow for a rigorous and effective treatment and analysis of extreme events. We will show how extreme value theory and large deviation theory allows for a better understanding of high-impact weather and climate extremes as well as of the basic dynamical properties of the atmosphere. We will introduce the basic theory and show applications on a range of datasets, including outputs of numerical models of various levels of complexity as well as observational 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.

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. Registration is not needed, but indication of interest would be helpful for planning purposes.

Public information:
The course will be streamed online in a Zoom webinar format. It will consist of 45 mins talks + 15 mins Q&A session.
We agreed on having the SC live streamed on Zoom through the vEGU platform. As we can dispose of 45 mins plus 15 mins Q&A, we will split ourselves like this:
- The first part, chaired by Remi Tailleux (25 mins), 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 (10 mins) and Gabriele Messori (5 mins), will illustrate some applications of thermodynamics to the study of the climate system and its general circulation.

Lecture notes and commented slides will be uploaded on the webpage of the course, within the vEGU21 programme, containing an extended version of the topics that will be touched in the short course. They will be on display and available for comments same as the other presentations at vEGU21.

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, Sebastian Breitenbach from CL division and Rachel Smedley from the GM division, 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. For registration please send a request via this email address (ecs-cl@egu.eu) prior to 15th April.

Forecasting and Early Warning Systems (EWSs) help societies prepare for and respond to all types of disasters, including those due to hydro-meteorological hazards. In recent years, there has been a consensus on the need for an interdisciplinary approach to forecasting, and communicating warnings and their inherent uncertainties. The integration of methods and knowledge such as risk, probabilistic and risk-based forecast, impact-based assessments, Information and Communication Technology (ICT) fields, social science and local knowledge can (1) improve the quality of forecast, (2) improve decision making and (3) support better communication of warnings and response. However, one of the biggest challenges is the need to collaborate across relevant disciplines. Therefore new ways of thinking are required on the necessary skills to facilitate more collaborative work.

This short course aims to highlight the benefits and skills required for an interdisciplinary approach in EWS in the form of a role-playing game and discussion. Participants will have the opportunity to understand more about the role of diverse disciplines, their importance in EWS and most importantly, collaborate with people from different backgrounds to come up with a successful solution. The game will be based on a hypothetical emergency situation, in which participants will be required to make decisions based on their assigned role. After the game, an active discussion with all participants will be carried out to propose take away action points on how to improve interdisciplinarity in EWS and how Early Career Scientist (ECS) can contribute to promoting this approach.
At the end of the short course participants should have:
(1) increased awareness and understanding of the roles of EWS actors
(2) Understanding of the necessity to engage and collaborate with professionals from different backgrounds
(3) Newly acquired skills to improve interdisciplinary working and communication

We especially encourage, but not limit, the participation of Early Career Scientists (ECS) interested in the field of Natural Hazards Social, Hydrological and Atmospheric Sciences as well as those who are already working or have in interest working in interdisciplinary fields.

In 2018, hydrologists from all over the world outlined twenty-three questions that remain unresolved by the scientific community, named Unsolved Problems in Hydrology (UPH). The discussion around them highlighted the need for science driven by technological innovations that is outcome- and/or product-specific. The EGU GA represents a meaningful opportunity for researchers to meet up and share their ideas, although sometimes the scale of the event makes it difficult to actually talk about future projects and develop research proposals. In this Call for Calls session, participants will engage in a sprint-like, competitive event where they will come up with innovative ideas to contribute to the solution of at least one of the UPH.

The session will provide the right atmosphere where researchers can discuss and think about a specific problem, and brainstorm initial ideas to gather information to write an abstract. Attendees are expected to make as much progress as possible. After the session, the participants will be able to continue working if needed. The expected outcome is a project with introduction and plan of action, including outputs such as a paper or collaboration, which will be presented as a short abstract and delivered before 5 pm CEST on the final day of EGU.

Given that the UPH encompasses issues across the hydrological system and human interactions, this session is open to all researchers in water resources and water security. Early-career scientists are particularly encouraged to participate to apply and enhance their current expertise and expand their research network.

SC5 – Techniques & software for data analysis

Programme group scientific officers: Michael Dietze, Anouk Beniest

SC5.1

With increasing data complexity and growing data volumes, effective and efficient data visualization for data analysis is becoming more important. Different data sets and analysis tasks require different visualization strategies. Geoscience data, being typically multivariate, multidimensional, time-varying, large and sometimes also with uncertainty, demands special attention and care.

This short course aims at providing an overview of commonly available visualization tools that are especially well suited to analyze earth science data sets. We demonstrate the functionality of two selected tools, the general-purpose tool ParaView (www.paraview.org) and the meteorology-specific Met.3D visualization framework (met3d.wavestoweather.de). We show how to easily create meaningful visualizations (including interactive and 3D displays) of gridded atmospheric, oceanic and earth system model data with these tools with only a few steps.

In Hamburg's geoscience community (including the German Climate Computing Centre DKRZ and Universität Hamburg), we have many years of experience in the visualization of earth science data sets. The goal of this workshop is to pass some of our knowledge on to you. More information will be available before the workshop at https://www.dkrz.de/egu2021.

Remote sensing data from Earth orbiting satellites have become indispensable in modern geo-spatial sciences. The technologies underlying the capture of remote sensing data have evolved over the decades which have resulted in an improvement in the data quality, rate of availability and processing.
The workshop will cover tasks such as generating Land Surface Temperature (LST) product from satellite imagery from scratch, extraction of information from ready-made products and raster algebra. Participants will go through a workflow that will present itself as a solution to a real life problem. The main Python libraries or frameworks to be used are rasterio, earthpy, pandas, matplotlib and geopandas. The data to be used will be Landsat 8 satellite imagery.
The first part of the workflow focuses on the extraction of intermediate products that are useful for the calculation of LST from satellite imagery. These products are Normalized Difference Vegetation Index (NDVI), Land Surface Emissivity (LSE) and Fractional Vegetation Cover (FVC). These products are not only useful for calculation of LST but are applicable in other remote sensing applications such as vegetation health monitoring and land cover classification. This section will also equip participants with raster algebra skills using Python.
The second part will cover the pre-processing activity of correcting Landsat 8 thermal bands for the extraction of LST and ultimately generate the LST. The participants will learn how to perform other mathematical operations on raster data using Python.
Finally, LST values at certain desired locations will be extracted. This will equip participants with skills on how to extract information stored as raster files to point features using geospatial Python libraries. In all sections of the workshop, intermediate results will be visualized within the Jupyter Notebook to give participants a hands-on feel of visualization with Python.
It is expected that at the end of a successful completion of the workshop, participants will be able to generate LST from scratch using Landsat 8 imagery and by extension all Landsat imagery with thermal bands. Also, participants should be able to derive other useful products like NDVI from any remote sensing image using the appropriate data and finally acquire raster processing skills useful in other applications.

Satellite based climate data records play an increasing role in climate monitoring and help to answer climate related questions. Nowadays satellite based climate data records cover a time period of several decades. EUMETSAT and it’s Satellite Application Facilities (SAF) provide a number of high quality climate data records for various geophysical variables, such as solar radiation, land surface temperature, cloud fractional cover, soil moisture, and many more, derived from both, geostationary and polar orbiting satellites.

These climate data records are free and open to everyone. They continue to be reprocessed to account for improvements of the algorithm and to include recent time periods. In addition to the data, free software tools, such as the CM SAF R Toolbox, are developed and provided by the SAF’s for users to work with the data.

This short course is an opportunity to get an overview about the climate data records available from the EUMETSAT Satellite Application Facilities, learn how to access them and gain some first experiences in how to work with the software tools provided.

EUMETSAT offers over 35 years of meteorological satellite data. New data consistency with previous satellites is ensured by intercalibration and reprocessing. This is a valuable resource for the geoscience communities. EUMETSAT produces 26% of the Essential Climate Variable records identified by the Global Climate Observing System that can be observed from space.

With the new satellite programmes, the volume and complexity of the data products will increase significantly, making it unfeasible for traditional workflows, relying on accessing local data holdings, to exploit these observations. EUMETSAT’s new Data Services, the subject of this course, address this issue.

In this short course you will learn:
• what EUMETSAT offers the geoscience communities within Europe (Data Store, Data Tailor, and visualisation service)
• how to set up access and how to use the GUIs and APIs, Jupiter notebooks and documentation will be available to take away

The Data Store provides online access for directly downloading satellite data via a web-based user interface and APIs usable in processing chains. Users can download the data in its original format or customise it before download by invoking the Data Tailor Service.

Under the climate change threat, we need to quantify the spatio-temporal trend of temperature and rainfall patterns to understand and evaluate the potential impacts of climate change on ecosystems services, energy fluxes and biogeochemical processes. There are wide range of global or regional scale climate data freely available in a gridded format that can be used in spatio-temporal analysis studies. These data can be derived directly from satellite remote sensing data or based on reanalysis of time series of weather stations data. Additionally, some gridded data are also developed by the combination of time series of remote sensing data and weather stations data.

Different methodologies have combined spatial data sets and nonparametric statistical methods, such as the Mann-Kendall (MK) test, to infer about the temporal trends of climatic variables. The MK test analyzes if there is, or not, a monotonic trend in the series by calculating difference between earlier and later data points in the time series. Very high positive differences are an indicator of increasing trend whereas very low negative differences indicate decreasing trends. A statistical significance is also calculated for each trend using the normalized test statistic Z. In addition to the trend calculation, it is also possible to quantify the magnitude of the trends. The magnitudes can be estimated by using the nonparametric Sen statistic, more specifically, the Sen’s slope estimator, which is given by the median of the slopes of each pair of points. To calculate the Sen’s slope, the times series data is ordered accordingly to the time (as function of time) and a confidence interval is provided for each slope value.
The objective of this workshop is to give an overview of where to obtain gridded climate data, provide a simple workflow for data wrangling and perform trend analysis on gridded climate data. During the workshop, the participants will learn how to handle and apply different operation on raster data and vector data in R. Some of the operation are: i) crop multiple raster using vector data and save as new files; ii) raster values check (e.g. outliers and NA); iii) conversion of raster into vector polygon data; iv) conversion of spatial data in tabular data (data frames); v) modify and reorganize data frames; vi) create and apply functions; vii) use conditions statements; viii) join operations; ix) create bivariate map; and x) save the results.

Natural hazards pose significant threats to public safety, infrastructure integrity, natural resources, and economic development. In recent years, the frequency and impacts of extreme events have increased substantially in many parts of the world fostering a paradigm shift from traditional stationary statistical models towards models capable of capturing the changing properties of extremes, i.e., nonstationary statistical models. The nonstationarity in such models can be defined by a temporal or process-informed dependence of the observed extremes on an explanatory variable (i.e., a physical driver). Further, a solely statistical-based model might lead to results inconsistent with physics, e.g. unrealistic wave heights in shallow waters. This highlights the need of traditional statistical models including physical constraints in the inference process.

The proposed short course presents the Matlab toolbox ProNEVA which enables users to perform Bayesian statistical analysis under the assumption of nonstationarity, and its latest extension ProNEVAwave specific for analyzing extreme wave heights considering physical constraints in the inference process. The main features of ProNEVA are: parameters estimation of Generalized Extreme Value distribution (GEV), Generalized Pareto distribution (GP), and Log Pearson type III distribution based on Bayesian inference approach; analysis under temporal and process-informed nonstationarity; uncertainty quantification; estimation of return period-return level values for nonstationary analysis (i.e., effective return level and waiting time). The extension ProNEVAwave is developed for statistical analysis of wave heights with the following features: events selection; parameter estimation of stationary GP distribution based on Bayesian inference considering physical constraints via informative priors; uncertainty quantification; estimation of return period-return level curves.

This hands-on short course will provide attendees with some basic knowledge of extreme value analysis under stationary and nonstationary assumptions. Attendees will have hands-on experience on how to apply ProNEVA and ProNEVAwave through a number of applications (e.g., modeling extreme wave heights).

GEOframe is a system for doing hydrology by computer (https://abouthydrology.blogspot.com/2015/03/jgrass-newage-essentials.html).  It is based on the OMS3/CSIP infrastructure, developed by USDA- ARS/Colorado State University.  OMS3/CSIP allows to build models by components, which perform simple task that can be joined together to build “Modelling Solutions”, suited to particular case studies. Components developed so far cover: meteorological data interpolation (Bancheri et al., 2018), terrain analysis (Abera et al., 2014), calibration tools (Formetta et al., 2011; Formetta et al., 2014), rainfall-runoff models (Bancheri et al., 2020; Formetta et al., 2014), evaporation and transpiration models, snow models (Formetta et al., 2014), Richards’ equations solvers, runoff propagation.

The modelling solution components are executed in parallel by the OMS3/CSIP engine. Besides, a further parallelization is made thanks to the spatial discretisation of the catchments in hydrological response units. GEOframe has been applied to catchments from few thousands of square meters to two hundred thousand square kilometers, and it is also used for operational forecasting in the Basilicata region in Italy. 

The short course introduces the system using some case studies already prepared and show how to join components, set the parameters, run the calibration and obtain results. The course will be based on the material already prepared for various Winter Schools on the topic, which allows the participants to use independently the system.

Bayesian approach to probability theory and statistics has various applications in hydrological sciences, particularly to solve inversion problems and to characterize model uncertainty. From calibrating a hydrological model to quantifying catchment transit time distribution, Bayesian approaches incorporate prior system knowledge that helps us to improve our understanding of the natural system. Using a number of practical case studies, this short course aims at providing a state-of-the-science overview of the usage of Bayesian statistics in different facets of hydrological modeling.

We kindly invite early career researchers (MSc students, PhD candidates, post-doctoral researchers) to attend this short course designed to address the fundamentals of Bayesian statistics and its particular applications in hydrology.

This will be the sixth year that the Hydroinformatics for Hydrology short course takes place during the EGU conference. Information to this and former short course topics can be found online on the homepage of the cooperating Young Hydrologic Society (http://younghs.com).

Data assimilation combines observational data with a numerical model. It is commonly used in numerical weather prediction, but is also applied in oceanography, hydrology and other areas of Earth system science. By integrating observations with models in a quantitative way, data assimilation allows to estimate model states with reduced uncertainty, e.g. to initialize model forecasts. Also, it can estimate parameters that control processes in the model or fluxes. Hence, it can provide information about non-observable quantities if the model represents those. The combination of modeled and observed data requires error estimates for both sources of information. In ensemble data assimilation the error in the model state is estimated by an ensemble of model state realizations. This uncertainty estimate is then used by the assimilation method like the ensemble Kalman filter or a particle filter.

To simplify the implementation and use of ensemble data assimilation, the Parallel Data Assimilation Framework (PDAF) has been developed. PDAF is a freely available open-source software (http://pdaf.awi.de) that provides ensemble-based data assimilation methods like the ensemble Kalman filter, but also allows to perform pure ensemble simulations. PDAF can be used from small toy problems running on notebook computers up to high-dimensional Earth system models running on supercomputers.

The course will, after a short introduction to the ensemble data assimilation methodology, provide a hands-on and interactive example of building a data assimilation system based on a simple numerical model. This practical introduction will prepare the participants to build a data assimilation system for their numerical models with PDAF and hence provide a quick start for applying ensemble assimilation to their individual problems.

This course is both for the novices as well as for data-assimilation experts. It will be useful for novices who have a modelling application and observations and are interested in applying data assimilation, but haven't found a starting point yet. Data-assimilation experts who want to enhance the performance of their applications, or are keen to accelerate development of new data-assimilation methods and new applications will also benefit from the course.

For the interactive hands-on example we will provide source code for download at http://pdaf.awi.de/EGU2021 from April 19.

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. In the second part of this short course, hands-on for X-ray image analyses is offered.

You have observed timeseries or observed fields from hydroclimatic variables (e.g., rainfall, wind, etc.) or from other environmental variables. You wish to generate synthetic ones that reproduce precisely the observed statistical properties, but you do not how to do it. No worries! Join us and you will find out!

The short course will introduce you to a unified method of stochastic modelling and the CoSMoS R-package that makes generation of random fields and of univariate or multivariate time series piece of cake. The generated random fields or time series preserve any desired probability distribution and correlation structure including features like spatial and temporal intermittency. We will talk about the stochastic properties of hydroclimatic processes such as precipitation, streamflow, wind, temperature, etc., and highlight features such as stationarity, cyclostationarity, marginal distributions, spatiotemporal correlations structures, and intermittency. We will explain how AR and multivariate AR models work and describe step-by-step the parent-Gaussian framework that allows precise and easy simulation of random fields and time series. Real-world examples include rainfall simulation at different spatiotemporal scales as well as simulating variables such as temperature, relative humidity, etc.

Early Career Scientists (ECS) and student are more than welcome! As always, we organize this short course in cooperation with the Young Hydrologic Society (YHS; younghs.com)!

This short course introduces and gives practical examples on how to use the TRACMASS Lagrangian trajectory code version 7 to study the oceans and the atmosphere. Lagrangian trajectories are a powerful tool for studying connectivity, transport, dispersion etc. in geophysical flows. TRACMASS v7.0 includes a variety of new features and has also been extensively rewritten to make it more user-friendly and improve performance.

We will provide a brief introduction to the algorithm used to solve trajectory positions in TRACMASS as well as showcase examples of case studies on a variety of spatial and temporal scales in oceanography and meteorology. Case studies will include: tracing deep water from the Southern Ocean to the Atlantic, calculating trajectories using data from satellite altimetry, etc. We will also demonstrate a new tool to post process and analyse trajectory data from TRACMASS.

A large part of the short course will be devoted to a walkthrough on how to download, install and configure TRACMASS. This will be followed by running TRACMASS on some example data from the NEMO ocean model and atmospheric reanalysis (ERA-5) and then analyse the results. The analysis will cover e.g. calculating Lagrangian stream functions, connectivity and some Lagrangian statistics like dispersion etc.

Participants will be able to set up TRACMASS for their own application and understand the results which will be particularly useful for early-career scientists looking to add new tools to their scientific arsenal. Users should bring their own laptops.
The course is aimed for those with no previous experience with Lagrangian trajectories but more advanced participants will also have the opportunity to further develop their skills. Basic knowledge of Linux/UNIX commands is necessary. Knowledge in Fortran and Python is preferable, but not necessary.

Quantitative geomorphological and environmental analysis requires the adoption of well–defined spatial domains as basic mapping units. They provide local boundaries to aggregate environmental and morphometric variables and to perform calculations, thus they identify the spatial scale of the analysis. Grid cells, typically aligned with a digital elevation model, are the standard mapping unit choice. A wiser choice is represented by slope units, irregular terrain partitions delimited by drainage and divide lines that maximise geomorphological homogeneity within each unit and geomorphological heterogeneity between neighbouring units. Adoption of slope units has the advantage of enforcing a strong relation with the underlying topography, absent in grid cell–based analyses, but their objective delineation is a challenge. A given study area admits different slope unit maps differing in number and size of units. Here, we describe a parametric delineation for slope units, using the r.slopeunits software in GRASS GIS.

The r.slopeunits software implements an algorithm that defines a mosaic of SUs bounded by drainage and divide networks based on iterative extraction of the boundaries of hydrological “half-basins” from terrain information available from a DEM. To single out individual SUs from the half-basins, r.slopeunits assumes that homogeneity (heterogeneity) within (between) SUs is controlled by the variability of terrain aspect in each SU. The procedure begins with the delineation of a set of a few large half-basins characterised by a large upslope contributing area, which is iterated - for half-basins not meeting size and homogeneity criteria - with decreasing values of the contributing area, until the entire study area is covered by a mosaic of SUs, of different sizes and shapes.

The aim of the short course is to enable the attendees to use r.slopeunits in their laptops. We will provide a Linux virtual machine (intended for VirtualBox, running on any operating system) containing the software and necessary libraries. Attendees will need basic understanding of GIS concepts, and they will be guided through the specifics of processing within GRASS GIS for execution of r.slopeunits. They will be guided through a complete example of slope unit delineation, starting from the import of the DTM into the GRASS GIS environment to the production of slope units in vector layer format.

The objective of this course is to teach geoscientists, engineers and researchers all the basics about 3D structural geological modeling using our open-source Python libraries: GemPy and GemGIS.

GemPy ([https://www.gempy.org/](https://www.gempy.org/)) is an implicit geological modeling library that in recent years have become a core component on the open source geoscientific ecosystem. Originally built to analyze uncertainty of structural models - by the use of Bayesian networks, GemPy is capable to represent complex geological geometries - e.g. folds, faults, unconformities - with a reduce number of parameters. In addition, GemPy provide an array of compatible addons and assets such as built-in visualization (powered by vtk), topology analysis, forward geophysics or volumetric kriging. GemGIS is compatible open-source geographic information processing library, capable of preprocessing spatial data such as vector data (shape files, geojson files, geopackages), raster data, data obtained from WMS services or XML/KML files.

The course will give an introduction to much of these functionality including step-by-step tutorials in Jupyter notebooks. Some of the topics will be

- Installation
- Your first model from scratch: conformable layers, unconformities, faults, geophysics, topology
- Modeling landscape: Short theoretical overview
- GemGIS: Importing data from QGIS to GemPy

The course is aimed at PhD students, early career scientist and programming enthusiasts. Jupyter notebooks will be provided and attendees are encourage to follow along programming. Simply just listening to familiarize with the software and its key features is also welcome.

The Magma Chamber Simulator (MCS) is a thermodynamically self-consistent computer code that simultaneously models complex magma mixing, crustal assimilation, and crystal fractionation processes in a user-constrained magmatic system. Using rigorous thermodynamics, MCS tracks its thermal, mass, and compositional (major/trace element, isotope, and phase equilibria) evolution.

MCS can be applied to a wide range of research subjects from the evolution and growth of the crust to origins of volcanic phenomena. More specifically, MCS can be used to model whole-rock, mineral, and melt inclusion major/trace element and isotopic data from natural systems. Among the many goals for such modeling are defining which processes dominate at a particular volcano/pluton, and documenting the temporal balance of mantle versus crust contributing to a magma system. MCS has broad appeal to interdisciplinary groups of petrologists, geochemists, and volcanologists, or anyone who is interested in how researchers try to replicate natural magmatic systems.

On this short course, we will provide an introduction on how MCS operates and what kind of input and output is related to it. To show this, we will run an example simulation accompanied with a visualization of the modeled system.

If they so wish, the attendees can run the example simulation on their personal computer or laptop. For those who want to do this, necessary information and instructions will be shared in the Session Materials.

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. In this networking session 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 virtual meeting with 2 minute ‘pop-up’ presentations outlining some challenges. These pop-ups are followed by chaired and structured outbreak group discussions. This short course lives by your input, so participants are engaged to actively crowd solve the presented challenges. To wrap up the session, solutions and suggestions from each topical group are presented to the whole session in a final discussion. 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 and if possible have your video turned on. You can get an idea of past crowd-solving sessions in summary blog posts from 2018 (EGU GM blog) and 2019 (EGU blog).

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 15, 2021. 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 last century, nonlinear sciences have greatly matured, moving from first ideas by Lewis Fry Richardson, passing through the evidence of the so-called deterministic chaos by Lorenz, up to the concept of fractals introduced by Mandelbrot. New paradigms have been introduced like scaling laws, scale invariance, self-organization, stochastic processes, predictability, tipping points, extreme events, and so on, involving both theoretical and methodological approaches, making nonlinear sciences a highly multidisciplinary field with an important role in fundamental geoscience.
During the last decades, methodologies, modelling and data analysis techniques have been significantly improved to provide a deeper understanding of nonlinear processes in geosciences, both testifying “classical” approaches and looking forward to future challenges and developments.
In this Townhall Meeting, some scientific officers of the Nonlinear Processes in Geosciences (NP) Division of EGU will provide their view on our understanding and challenges within our NP community. This is an excellent opportunity, especially for the young scientists, to meet with the experts and discuss the future of our community. We will be glad to follow a bottom-up approach in which the community, both established researchers and the Early Career Scientists, is invited to propose specific topics, themes, aspects, and questions for an open discussion with the NP officers about future opportunities, challenges, and directions in our field.

The representatives of the Early-Career Scientist (ECS) and outreach team of the Climate division welcome all ECS during this networking event. The event is based on Gathertown Game and the objective is to create an opportunity for new young scientists to meet leading scientists in climate, enhance their network and have some feedback about career life in climate science....

This networking event will be organized via the online platform gather.town (https://gather.town/i/wwsPoATP). It is a video-calling space that lets multiple people hold separate conversations in parallel, walking in and out of those conversations (just as in real life) with your own “avatar”. You do not need any prior experience with gather.town (but for those eager: it always helps to check out online resources and tips & tricks). The best tip we found: You can make your Avatar dance by pressing “Z” on your keyboard (use a Google Chrome or Firefox browser).

Join us and have fun.

Public information:
Following on from the How to influence policy through engaging with Parliaments Short Course, this networking session will give attendees the opportunity to practice pitching their research findings or policy ask to a policymaker. The interactive nature of this session will give attendees the opportunity to develop their skills in presenting their research to a policy audience. It will begin with a brief overview of principles of effective communication with policymakers, then attendees will have the opportunity to do a quick pitch of their research findings and policy ask, before receiving constructive feedback from session conveners and other attendees. It will also give attendees the chance to identify potential collaborations with other members of EGU with similar policy interests.

While it is recommended that attendees also attend the How to influence policy through engaging with Parliaments Short Course that will be hosted directly before this networking session, it is not necessary or a prerequisite to joining. The topics discussed during the session will be complementary to the Short Course but will also be useful as stand-alone tools. Attendees should come with an idea in their head of the ‘policy ask’ they want to pitch (e.g. a change in law, new legislation or regulation, change in government priority or something else). This may relate to their own research or that of others.

Moderator: Chloe Hill, EGU Policy Officer

Speakers:
- Sarah Foxen: Knowledge Exchange Lead at POST, UK Parliament
- Theodoros Karapiperis, Head of Scientific Foresight (STOA) Unit at European Parliament

TM – Townhall Meetings

Programme group chair: Peter van der Beek

TM1 EDI

Availability of research data, together with the availability of methods/software and open access to the resulting publications, has become an increasingly accepted set of pillars for reproducible science. While more and more journals have moved to openness regarding access of articles, the shift to demanding (or at least strongly encouraging) availability of the underlying data and even software has emerged just recently. For example, since August 2019, the AGU journals enforce major parts of the FAIR principles, which can impose some head scratching during and after submission. Likewise, when asking data repository staff, what data of a Structure-from-Motion study actually should be provided (pictures, calculated point clouds, point cloud derivatives, derivatives of derivatives?), one can get a rich variety of replies. Obviously, as with all freshly laid out directions, trails need time and people to become highways.

Thus, it is now time to ask scientists for their suggestions about how to form this trail into a highway. Which key information should be provided by journals and data repository platforms to simplify the submission process while likewise safeguarding the necessary meta data depth and low level accessibility constraints? What are adequate time lines and work flows for authors? Which type and aggregation stage of data should (or should not) be part of a repository? How can access restriction requirements for different groups be implemented? How can different data repository contents be organised to make real value of the rapidly expanding data source?

This townhall meeting invites researchers from all geoscience disciplines to share their experience with the process of providing data along with manuscripts. Our aim is, besides discussing the above questions, to develop mechanisms to lower learning curves, and to facilitate workflows, for authors, data curators and journal editors and reviewers. We want to fuse a group of active people that collect feedback and ideas, which will be used to ultimately create and share one page how-to’s on fruitful ways to create data repositories, utilise pre-print servers, and submit articles in agreement with open science policies.

We plan to provide mechanisms that safeguard a high degree of auditorium interaction and intend to assemble a panel of publishers, editors, data curators, and scientists.

Publishing is an essential and integral part of scientific life. During a scientist’s career, one may act as author, reviewer and editor. In each of these roles one may experience frustrating moments because of diverging expectations regarding one’s own and another person’s role in this agent triangle during the publication process. It is frustrating as author and editor to get ten lines of review text, or reviews that are merely copy-editing notes. It is frustrating as reviewer to be left with unclear definitions of quality thresholds, recommendation guidelines, and obviously bad manuscripts that should have never gone out for review.

Often, such frustrations arise from a lack of common agreements – across journals and across disciplines – on the expectations and limitations of the roles of all three publication agents (author, reviewer, editor, but all of them scientists by training and at heart). What may be an expected task in journal A could be a don’t-do for journal B, and quite often there is no way to infer that expectation from a journal’s website. Thus, in an environment of ever increasing publication numbers, pressure on all three roles is intense. A consensus regarding transparent, generic and helpful guidelines on the definitions, duties and expected deliverables of authors, reviewers and editors is needed and overdue.

The goal of this Townhall meeting is to shed light onto experiences of authors, reviewers and editors across geoscientific disciplines. We want to collect and share examples of good practice and debate a minimum set of guidelines for each of the three groups of publication agents. We invite researchers from all geoscience disciplines to share their experiences and ideas with the audience and the panel, and intend to share the outcomes of this community-driven discussion transparently and widely.

Scientific drilling has transformed the understanding of our planet by addressing some of the most fundamental questions about Earth´s dynamic history, processes, and structure, and by opening up new lines of inquiry. Understanding climate, sea-level and environmental changes, geohazards, natural resources, the structure and evolution of the Earth’s crust and the nature and extent of the deep biosphere all require having access to information recorded in subsurface layers.

Two major and complementary international programs undertake drilling for the scientific community: IODP (International Ocean Discovery Program) and ICDP (International Continental Scientific Drilling Program), in oceanic and continental environments respectively. This Townhall meeting will be the opportunity to share our views on exciting challenges to take up for a better understanding of the Earth system and its changing environment and to network with colleagues.

PTAL is a research project founded by the European Commission through the H2020 program, which is aimed to provide the scientific community with a novel library of terrestrial analogue materials that have been selected according to their similarity to well-known Martian geological contexts (https://ptal.eu/). Planned to be released to public on January 2022, the PTAL platform (http://erica.uva.es/PTAL/) will provide future users with free access to complementary spectroscopic and diffractometric data gathered from over 100 terrestrial analogues. Beside the use of commercial instruments, this database stands out for providing access to data collected by means of analytical spare models (FS) and representative prototypes of Raman (RLS and SuperCam simulators) VNIR (MicrOmega-FS) and LIBS (ChemCam-FS) systems onboard the Perseverance and Rosalind Franklin rovers soon landing on Mars. As the PTAL database is meant to facilitate the scientific exploitation of the data returned by Mars202
0 and ExoMars missions, this townhall meeting is meant to present the final version of the online PTAL platform and discuss with attendees about PTAL analytical data and spectroscopic tools.

The aim of this townhall meeting is to bring together soil-modeling researchers for developing new activities and future perspectives on modeling soil systems. Contributions are welcome with a short announcement ahead of the meeting to the conveners. Formed to consortium in 2016, we aim for integrating and advancing soil systems modeling, data collection, and observational capabilities. ISMC is a community-based effort that builds on voluntary contributions and scientists, stakeholders and institutions can sign up freely (https://soil-modeling.org/). ISMC is organized around three science panels that parallels a broad workflow from data collection (DO-LINK) to model development and testing (Soil-MIP) to engagement with different scientific communities (CROSS-CONNECT). Together, these panels jointly foster the development of soil modelling tools, support, expertise and knowledge transfer. We anticipate that the discussion will be facilitated through a report of the state-of-affairs an d the activities of the three science panels, followed by an open and engaging dialog with the attendees. The meeting is centred around an open and engaging dialog among the attendees and initiated by a report of the state-of-affairs and the activities of the three science panels, followed by an open and engaging dialog with the attendees.

In this Townhall meeting we will update you on the latest developments within the StraboSpot//EPOS collaboration and demonstrate recently developed tools for experimental rock physics and microscopy.

StraboSpot is an EarthCube sponsored US initiative that is developing mobile and desktop applications to facilitate the collection and curation of field geology, microstructures, and experimental rock deformation data.

EPOS (European Plate Observing System) is a pan-European e-infrastructure project with the goal of improving and facilitating the access, use, and re-use of solid Earth science data. The Multi-scale laboratories are a subdivision within EPOS and responsible for laboratory-generated data, including microscopy and experimental rock deformation.

The StraboSpot//EPOS collaboration aims at harmonizing both initiatives, to ensure both systems are able to communicate with each other and can thus be linked. StraboSpot provides the tools to collect the data, while EPOS provides a platform to make the data available.

In this multidisciplinary Townhall session, we will discuss the current challenges of the publication system, and explore some of the emerging opportunities which aim to render it more open and fair. This event follows a series of engaging articles published in the European Journal of Soil Science in late 2020, initiated by Professor Philippe Baveye from Saint Loup Research Institute in France, on the issues of bypass and hyperbole. A response authored by an international network of early career soil scientists also showcased the difficulties faced by reviewers, as well as the opportunities provided by open access publishing. These likely represent challenges faced across a broad array of geoscience disciplines. The goal of this Townhall is to bring together participants from all EGU divisions to share their perspectives on the limitations of the current publication system, and the emerging possibilities to make it more open and fair to all.

A diverse and international panel comprising both an early career and an established scientist, together with representatives from journal publishing platforms with varying open access options, will present their own perspectives on the challenges and new opportunities in publication practices, which will be followed by an open discussion by all interested conference participants.

Bringing the complementary expertise and perspectives of mountain scientists from across regions and disciplines together to discuss outstanding challenges is beginning to drive substantial progress in science, practice, and policy. This splinter meeting, convened by the Mountain Research Initiative (MRI) and GEO Mountains, intents to further strengthen these efforts by providing a forum in which to discuss – and hopefully collectively identify feasible and practical solutions to – a series of broad challenges that have been identified through work recently carried out under the auspices of the Mountain Research Initiative (MRI) and/or GEO Mountains (see references below for further details).

Briefly, the MRI is a scientific networking organization that seeks to drive and connect mountain research across disciplines and regions. The MRI’s Mountain Observatories and Elevation Dependent Climate Change Working Groups – in collaboration with GEO Mountains – are tasked, inter alia, with compiling a comprehensive inventory of mountain observatories and their associated datasets, including reliable information as to their availability for use. We also strive to improve the incompatibility of observations from mountain sites globally (e.g. by proposing common standards).

The following questions summarise some of the challenges that have been identified:

- How can we help improve the density of in situ monitoring instrumentation where this has been identified to be comparatively lacking (e.g. the mountains of Africa, South America, and Asia, and along transects across wide elevation gradients)?

- How can the ongoing shift from thematic to multi-disciplinary observations at mountain sites be accelerated?

- How can we collect and make available appropriate metadata on existing mountain networks and how should we best advocate for / incentivise the free and open sharing of existing datasets?

- How can greater emphasis be placed on obtaining useful socio-economic data in mountainous regions which, whilst critical, is currently often overlooked at the expense of biophysical data?

- How appropriate are global gridded environmental datasets (which can provide extensive spatial coverage) in mountainous applications, given that their spatial resolution may be limited and/or their reliability compromised in complex terrain?

- From a preliminary set of so-called Essential Mountain Climate Variables, how should we go about formalizing a pragmatic set of so-called Essential Mountain Climate Variables and their associated observation requirements?

The splinter meeting format will combine both plenary and break-out group discussions using an online virtual tool. All interested parties are warmly welcomed to attend and share their views on these important questions.

The outcomes of the discussion will represent important contributions from the community to the activities of the MRI’s Working Groups and GEO Mountains, and will accordingly be integrated into the work programmes and fully acknowledged. Conversely, we expect these discussions to inspire new collaborations and prospects for individual researchers – especially early career researchers - who wish to contribute to and be given recognition for participation in this collective effort.

For further information, please contact GEO Mountains Scientific Project Officer, Dr. James Thornton (james.thornton@unibe.ch).

Acquisition and analysis of geochemical data are pervasive in the Earth, environmental, and planetary sciences, but very little of it is FAIR (Findable, Accessible, Interoperable and Reusable). The need for global standards and best practices for geochemical data is increasingly urgent so that scientists can better share geochemical data in a global network of distributed databases. Standard protocols for exchanging geochemical data among distributed data systems, and for making software tools that support the management, publication, and preservation of geochemical data interoperable (see vEGU21 session ESSI3.9) still need to be defined and approved by a global community. Best practices need to be define for researchers and labs to consistently and comprehensively describe samples, data acquisition procedures, and data quality, and these need to be endorsed and promoted. Discovery in many fields will benefit from a global geochemical data network, from the study of global climate ch ange, to present and past biogeochemical cycles, to magmatic processes, to the origin and evolution of our solar system. This Splinter Meeting is intended to present and broaden participation in OneGeochemistry, an initiative to build a global geochemical network that develops and adopts geochemical data standards and approaches for their technical and organizational governance.

This meeting is to discuss and co-ordinate the production of large-sample hydrological datasets worldwide. We would like to bring together people creating and/or using large samples of catchments, to develop collaborations, brainstorm ideas, report on progress of current projects, and discuss concrete issues related to data format and technical procedures in order to facilitate data exchange. This meeting is organised as part of the Panta Rhei working group on Large Sample Hydrology.
