The ISIMIP Groundwater sector is new to the ISIMIP family. In this splinter meeting, we will discuss the progress of the Groundwater sector and upcoming model outputs we anticipate for this sector. This meeting is open for current sector participants and we encourage other groundwater modelers working at large-scale to join us too.

This splinter meeting aims to bring together scientists who use stable isotopes to study the critical zone. The meeting will allow ample time for networking, to meet other researchers in the field and to catch up with colleagues. It will also provide an update on the activities of the WATSON Cost Action (https://watson-cost.eu/). The splinter meeting is open to all critical zone scientists and anyone who wants to learn more about the WATSON Cost Action.

The International Commission on Human-Water Feedbacks of the International Association of Hydrological Sciences (IAHS) was founded in 2023 to capitalise on the momentum of the scientific decade Panta Rhei – Change in Hydrology and Society (2013–2023).
We focus on the feedbacks between humans and water over decadal and centennial time scales. We therefore mainly consider changes that involve a two-way coupling between human actions and water quantity and quality, i.e. how the water environment and humans coevolve. We are inclusive and interdisciplinary and invite all interested people, regardless of their field, be it social sciences, economics, engineering, hydrology, etc., from all career levels and regardless of memberships in commissions or IAHS.
Come to our splinter meeting when interested in collaborating and discussing on Human-Water Feedbacks, e.g. sharing knowledge, information, papers and organise joint studies and activities.

The meeting will bring together international scientists and practitioners working with models of human-water interactions with the goal of simulating scenarios or transformational and robust adaptation to water scarcity and climate change under deep uncertainty.

During the 2024 EGU General Assembly, the first in-person meeting of the Joint Working Group “Tailored Parameterization Strategies for Climate Applications of Satellite Gravimetry” of the Inter-Commission Committee Geodesy for Climate Research (ICCC) of the International Association of Geodesy (IAG) will take place.
This working group focuses on identifying and implementing spatiotemporally tailored parameterization strategies for satellite gravimetry observations designed for different climate applications. Building up from the simulation environments implemented in previous working groups, parameter models can be evaluated concerning their capabilities to represent climate-related mass transport signals and their feasibility in real data applications. To envision the possibilities that will arise with upcoming satellite gravity missions, improvements expected from MAGIC and future mission concepts shall be investigated next to current single-pair satellite GRACE-type missions. The parameter models shall be defined in close interaction with the respective applications to identify the main criteria to allow new science to emerge from the advanced parameterization strategies.
In the meeting, the newly launched JWG will discuss planned activities, possible collaboration, and future research activities.

Some years ago a group of interested geoscientists aimed to establish an international research network related to the topic "mountain glaciations". Two application for a COST action to create such a network have been prepared and submitted, unfortunately without success but with partly encouraging feedback. After pausing all related activies during the Covid 19 pandemic, the former coordinators of these applications want to utilise the opportunity that many previously involved or potentially interested colleagues will gather at the EGU General Assembly to discuss possibilities of a future revival of such activities in whatever format. This splinter meeting will be related to a proposed scientific session at EGU and should make former and potential future directions of this initiative public.

The splinter meeting will inform about the joint forces of the Horizon Europe project group of AVENGERS, EYE-CLIMA, and PARIS and offers a discussion platform for project activities.
The shared objective is to improve emissions data to support the implementation of the Paris Agreement. The projects provide GHG and aerosol emissions estimates using observation-based methods to improve estimates of national emissions and national greenhouse gas inventories (NGHGIs). They collaborate with NGHGI stakeholders, government entities, NGOs, and policy makers.

Allin-Wayra is the new IGAC Activity on small sensors. Do you use low-cost sensors or small small sensors in your atmospheric science research? Would you like to connect with others in the community? Then come to our splinter meeting and learn more about Allin Wayra, what we offer and how you can be involved. Our mission is to construct a diverse, inclusive, global community of practice around small sensors. Allin Wayra aims to advance knowledge and responsible use of small sensors in air quality and atmospheric science, with a particular focus on regions lacking air quality measurements. In the context of the activity, we will also address urgent issues related to small sensors in atmospheric science, foster capacity, and champion accessibility through collaborative initiatives. Learn more, provide input on directions for the activity and exchange with colleagues.

EXCITE is a Horizon Europe project, aiming to integrate X-ray and electron microscopy techniques applied to earth materials and to make those accessible for new and existing users.

The World Heat Flow Database Project aims to develop a new research data infrastructure for the IHFC Global Heat Flow Database that offers a one-stop shop for comprehensive information on heat-flow related data, publications, projects, and researchers. Supported by the International Heat Flow Commission (IHFC), this new user-oriented web service will offer to the geoscientific community quality-proofed, up-to-date, well-documented, extended, enriched, and restructured heat-flow data. The project supports the Global Heat Flow Data Assessment Project, led by IHFC and Task Force VIII of the International Lithosphere Program (ILP).

The splinter meeting will be an intermediate step in the global stakeholder process on the platform development.

We will report on the status of AdriaArray – a seismic experiment to cover the Adriatic Plate and its actively deforming margins by a dense broad-band seismic network. We will discuss the time schedule, participating institutions, mobile station pools, maps of temporary station distribution, station coverage, data transmission and access. We will also report on the work of Collaborative Research Groups. Invited scientific contributions will be presented during the splinter meeting too. We will share the outcomes of the AdriaArray meeting in Sofia, Bulgaria, 12. - 15. March 2024.

The Deep-time Model Intercomparison Project (DeepMIP-Eocene; https://www.deepmip.org/), is a large, international effort aimed at improving our understanding of climate during the early Eocene and PETM. In this splinter session, we will bring together the paleoclimate data and modelling communities to evaluate lessons learned from phase one of DeepMIP-Eocene (2016-2022) and explore future directions for phase two (2023-onwards).

This is the mid-term project meeting for the European metrology project isoMET funded by EURAMET.

One of the easiest ways that scientists can start engaging with policymaking is through the established, institutionalised mechanisms hosted by the European Commission that aim to collect expert input and feedback on their legislative proposals. This Short Course will provide participants with all the information that they need to start engaging with these formal engagement processes. The convening team and invited experts will provide an overview of a range of Commission-driven mechanisms including the EU Transparency Register, EU Consultations, and EU Expert Groups.

Make sure you bring your laptop so that you can join the walkthrough of the European Commission website and access these mechanisms.

As the amount of information needed to make an informed decision that adequately considers policy options increases, so too does the need for scientific evidence and those who are able to communicate it accurately and concisely. This role, between science and policy, is becoming increasingly recognised as a necessary profession with the number of knowledge brokers and those working on the interface expanding.

But what does a career in between science and policy look like? What types of positions exist and what skills do professionals who work on the science-policy interface need? Join us in this session to meet those working across the science-policy spectrum, learn about how they developed the necessary skills, and find out what their tips are for those who want to take the next step in their own career!

The European Union’s proposed Nature Restoration Law aims to provide essential guidance and support to restore ecosystems, habitats, and species across the EU’s land and sea areas. Expertise from researchers has played a vital role in creating and supporting this legislation that not only aims to restore degraded ecosystems but also improve soil health and water management, support the mitigation of climate change, and increase Europe’s resilience to droughts, floods, and other extreme weather events.

During this interactive session, experts involved in the creation of the EU Nature Restoration Law will share insights on the legislation process, the decisions that were taken, how scientific information was used to support the process, and what the next steps will be. Members of the EGU Biodiversity Task Force will also share their experiences engaging with this policy and the lessons that they learned along the way.

This session will not only provide participants with information on the Nature Restoration Law but also on how scientists can engage with the European Parliament in other legislative areas.

Understanding the aspects of your research and expertise that are relevant and of interest to policymakers is a key component of engaging in the policymaking process. This session will give you the opportunity to present the key aspects of your research to a panel of policymakers and those working on the science-policy interface! The panel will then give their feedback and provide insights on areas that you can improve on when discussing your research with policymakers in the future. This will not only allow you to develop your science-policy presentation and communication skills but also highlight areas that you can consider including to ensure that your research resonates with the policy community moving forward! The panel will also provide feedback on the policy areas in which they believe your research could be relevant, including current and upcoming policies.

The panel will assess up to eight scientists during this session. Timeslots will be allocated on a first-come, first-serve basis. You can submit your topic for consideration here: https://www.egu.eu/forms/Pitching4Policy/

This interactive Short Course will provide practical examples from EGU’s Policy Programme - including the Science-Policy Pairing Scheme, Science for Policy Working Group, and Biodiversity Task Force - and explain how these initiatives can be replicated.

During the first half of this session, leaders from these initiatives will be invited to present their experiences and give practical insights from the lessons that they learned. Session participants will then be invited to share their own experiences and brainstorm potential methods of creating science-policy spaces and dialogues within their own scientific organisations and research institutes.

Please bring questions and some of the challenges that you or your organisation is experiencing so that these can be discussed!

Policy briefs are concise, accessible documents that aim to communicate the practical implications of research to a particular policy audience and provide them with solutions to a specific issue. Although policy briefs are just one method to communicate information to a policy audience, they can be a valuable communication tool when effectively written and disseminated.

This Splinter Meeting will be run in the form of an interactive workshop. Participants will be provided with tips and tools to create their own policy brief as well as interactive exercises to work on with other attendees and the session’s leaders.

Participants are requested to bring along one of their (single-authored or collaborative) publications to use during the workshop. If attendees do not yet have any publications, they may bring along an article authored by someone else that they are familiar with.

The objective of Task Force VIII of the International Lithosphere Program (ILP) is to coordinate the "Global Heat Flow Data Assessment Project" in support of the International Heat Flow Commission (IHFC). The splinter meeting of the ILP Task Force will be used to present our activities, the current status, on-going work, and the next steps of the ILP Task Force. It opens space for networking and creating connections to other activities.

EOV's are essential ocean variables, that reflect physical, chemical, or biological processes in the oceanic system. EOV's are defined by the Ocean Observations Physics and Climate Panel (OOPC) of the Global Ocean Observing System (GOOS), which in turn is led by the Intergovernmental Oceanographic Commission (IOC) of UNESCO.
In a collaborative joint development (IHFC of IUGG, TF8 of ILP), the definition of a new EOV is prepared that reflects the heat flow at the interface between lithosphere and oceanic hydrosphere. Heat-flow and oceanic experts will discuss and develop the foundation for such a new EOV definition. During the open splinter meeting, the process will be introduced to interested EGU attendees. This open meeting is followed by a two-day writing workshop.

Welcome to our splinter meeting on the science-policy-interface! We would love to exchange ideas, network, share experiences and insights with scientists, science managers, science communicators, and policymakers alike. Whether you're deeply involved in policy discussions or eager to learn more about how science informs policy-making, you are warmly welcome to join us for snacks and drinks!

We also invite you to continue the dialogue at our session on Thursday, "EOS4.1 Science Policy Interface: Shaping Debates" (https://meetingorganizer.copernicus.org/EGU24/session/49288). This session will identify the most effective formats for science-policy engagement and highlighting success stories and lessons learned from scientists and communicators who have engaged in policy and made critical societal impacts – either on a European, national, or local level.

This splinter meeting aims to have a short report on the UPFLOW project and start brainstorming with the European community on future European OBS initiatives and on how to improve OBS experiments. From early-stage planning, pre- and post-processing, to publishing data reports and sharing final outputs. So far exchange between different institutes and projects has been limited. We want to encourage the exchange of knowledge in the European OBS community, improve current practices and develop new strategies which could ease challenges for future OBS projects.

The Drought in the Anthropocene research network connects scientists that aim to gain a better understanding of the feedbacks between drought and human society at different scales.
As the IAHS HELPING scientific decade has just started, the Drought in the Anthropocene research network is collecting new collaborative ideas.
We will hold discussions around our 3 new research questions, together with the 3 questions of the Panta Rhei decade, and see how we can proceed working on solving these.

The Working Group (WG) "Co-Creating Water Knowledge" of the HELPING Initiative of IAHS (https://iahs.info/Initiatives/Topic-for-the-Next-IAHS-decade/helping-working-groups/) is active as a community of practice of researchers on different topics, working in understanding how the concept of co-creation can be used to integrate local and indigenous knowledge in hydrological sciences, and how hydrological knowledge can be integrated into them. This Splinter Meeting is an in-person opportunity to meet the WG and follow up on its activities.

The IAHS Drought in Mountain Regions Working Group is working within the IAHS HELPING decade. It is a global initiative including scientists and practitioners working on droughts in mountain regions. We aim at organizing an on-site meeting at EGU to meet all participants to this WG who are also at EGU.

The Floods Working Group (FWG) of the Past Global Changes project (PAGES) aims to bring together all the scientific communities reconstructing past floods (historians, geologists, geographers, biologists, etc.) and those studying current and future floods (hydrologists, modellers, statisticians, etc.) to coordinate, synthesize and promote data and results on the natural variability of floods. The splinter meeting at the EGU 2024 is the 2024 annual meeting of the FWG and the kick-off meeting of the third phase 2024-2026 of the working group. During the meeting, the steering committee will propose and discuss the scientific activities planned for the next three years: pilot projects, special issues, topic sessions and workshops and a new call for the Open-access flood metadata base. The splinter meeting is open to FWG Group members, early-career researchers and anyone interested.

IRISCC is a new European Research Infrastructure project providing services for research on Climate Change Risks. The splinter meeting will facilitate the start up phase of the IRISCC project and interaction with its target groups.

Adaptation to climate change requires in-depth understanding of climate change driven risks, including their determinants (hazards, exposure and vulnerabilities) and impacts to human, production and natural systems. Integrated Research Infrastructure Services for Climate Change Risks (IRISCC) is a consortium of diverse and complementary leading research infrastructures (RIs) covering disciplines from natural sciences to social sciences, across different domains and sectors. IRISCC provides scientific and knowledge services to foster cutting-edge research and evidence-based policymaking to improve Europe's resilience to climate change. IRISCC ensures a “one-stop-shop” for various user communities on climate change risk related RI services by setting up a dedicated Catalogue of services and related access management system both for granting transnational (onsite and remote) and offering virtual access. The Catalogue of services will be built through three consecutive releases, each
delivering increasingly integrated services to its user communities. The IRISCC service integration will include Service Design Labs employing co-design and transdisciplinary action, and Service Demonstrators benchmarking the integrated cross-RI services. In addition to services aimed towards the scientific community, IRISCC will offer knowledge services aimed towards policymakers and other stakeholders. This is done together with risk management platforms. The research enabled by IRISCC contributes to future reports on climate change effects (IPCC, IPBES) as well as policy- and decision-making to meet the targets of climate adaptation strategies. IRISCC contributes to training a new generation of scientists to efficiently use RI services and for data stewardship. Data from IRISCC will be open and made available in compliance with FAIR principles and linked to European initiatives such as EOSC. Strong links will be created between IRISCC and current and future efforts under Horizon.

"The time for climate action is now. Science is critical in shaping the policies and actions to tackle the global climate change challenge,” said former IPCC Chair Hoesung Lee. Scientist Rebellion is an international movement of scientists and scholars who are extremely concerned about the climate and ecological crisis and believe the scientific community has the responsibility to step up and join the forefront of the environmental movement.
Unless those who are best placed to understand this crisis behave according to the emergency we live in, we cannot expect the public to do the same. The latest IPCC report notes “Any further delay in concerted action will miss a brief and rapidly closing window of opportunity to secure a livable and sustainable future for all.”
We believe that we must expose the reality and severity of the climate and ecological emergency through nonviolent direct actions, including civil disobedience. In this Splinter meeting we would like to share how we work and what we do. If you want to have a chat with some of us to see if this is a network you would like to join, feel free to stop by at this informative splinter meeting organized by EGU participants who are also member of Scientist Rebellion.

The process of transforming research outputs into policy and practice outcomes is described using various terms influenced by factors such as geography, time, domain, trends, and personal preferences. Research translation, knowledge translation, research utilization, knowledge transfer, and knowledge-to-action, among others, are some of these keywords. Regardless of the word choice, there is a growing global interest in this paradigm across diverse disciplines. The reason for this is the widespread acknowledgment that the conventional steps of knowledge creation (primary research), knowledge distillation (systematic reviews and guidelines), and knowledge dissemination (journal publications and presentations) fall short in ensuring that users beyond academia in industry, government and community can effectively leverage scientific knowledge for demonstrable real-world changes. This is especially important now as the world races to achieve just and timely decarbonisation and sustainabl e development.

Whilst knowledge translation practices focus primarily on the gap between research outputs and outcomes, gaps between evidence and decision-making exist at every stage of the research and development pipeline, spanning research infrastructure to long-term positive impacts for societies, environments and economies. In this meeting, we will share knowledge translation initiatives undertaken within research infrastructures AuScope (in the Australian context) and EPOS (in the European context), who support diverse users in academia, industry, government and community across those continents, respectively. We invite you, as a member of the global research and user community, to join us in exploring gaps in research innovation ecosystems around the world, and creative ways that we can work together to overcome them.

AntClimNow invites researchers, and especially ECRs, with an interest in near-term Antarctic climate variability to a 2-part workshop.
In Part 1, we will introduce AntClimNow’s Antarctic Climate Indicators project and invite participants to explore ways to characterise and visualise the state of all components of the Antarctic Climate System (atmosphere, ocean, ice).
Part 2 aims to provide an informal forum to network and exchange information on ongoing and planned work to apply machine learning techniques to help answer major science questions in Antarctic climate science.
Anyone interested in either aspect is encouraged to attend both sessions to join our discussions and look for future opportunities to collaborate.

Meeting for PAGES PlioMioVAR Working Group.

Discuss advances in tsunami modelling within the European tsunami community, related to ongoing progress in EU projects, as well as community building (Global Tsunami Model, EPOS).

PAGES welcomes all those interested in past global changes. You are much welcome to come and ask questions, whether it is about PAGES activities, how to organize one, how to attend one, or about the special events, such as the open science meeting(OSM in 2024 in Shanghai) or the topical science meeting . All the questions about PAGES will be welcome. We hope to make you more familiar with PAGES.

Cryospheric-specific climate interventions focused on sea level rise have been discussed for at least the past 40 years, but 2023 has had a significant increase in these discussions including several new research papers, two community workshops, and an AGU Town Hall event. The workshops took place in Chicago (Oct 2/3) and Stanford (Dec 9/10), and included ~60 glaciologists. Methods discussed focused mainly on ocean interventions (blocking warm water from reaching the ice sheet) and subglacial interventions (removing subglacial water or heat to slow down ice streams).
We seek broad community input on what a responsible intervention strategy would look like, how to think about the risks of intervening (or not intervening) to reduce rates of sea-level rise, and additional intervention approaches or other methods to reduce sea level rise rates beyond the necessary (but perhaps now insufficient) step of emission reduction.

A meeting for anyone interested in contributing and/or using ADMAP digital magnetic anomaly products in Antarctica and the Southern Ocean. We aim to summarize and identify newly available data sets, and discuss progress towards the next version of the group's compilation product.

Several initiatives are developing to facilitate co-ordinated analysis of legacy core material and associated assets from the IODP and its predecessors. As part of the PAGES-PlioMioVAR initiative we here seek presentation and discussion of potential Pliocene-focussed legacy projects, which could be focussed by region, time interval, proxy etc.
The meeting is open to anyone interested in developing a legacy project, but spaces are limited so please express your interest by emailing the convenors.

The SURFEIT project, managed by the British Antarctic Survey (PI Louise Sime), will be running a project meeting as many international project partners will be attending EGU.

The gravity field community has become familiar with the ICGEM service during the last 20 years. ICGEM is now planning to realise the need for scientific and technical expansion, modernisation, and upgrading of the existing database, as well as its calculation and visualisation components, in which the scientific community and society have a great interest. At this meeting, we would like to discuss about the future goals and plans of the ICGEM service with global gravity field model (GGM) developers, experts, geoscientists and users. We would like to address why it is important to know how to respond to the growing need and demand for improved and quality-assured, well-documented GGMs and related products with additional types of datasets and data representations that are enriched with metadata and provided in a sustainable and freely accessible research data infrastructure. Over the next 3 years, ICGEM will be rebuilt and integrated with other geodetic services with the aim of servi ng global users. Such a platform will make the quality-assured data and products exchangeable and supports education, science, and society. We should therefore discuss future steps and exchange ideas as the community of experts and users.

The communication gap that exists between scientists and journalists is well established, but the first step to closing it is to understand why it exists. This by-invitation only meeting will be recorded to provide educational material for scientists and journalists working on the science-media interface. It will offer room for open discussion on the expectations and challenges of each side and explore new ways that both can find to share science more accurately and effectively with the world.

Earthquake hazard analyses rely on the availability of seismogenic source models. The recently released European Fault-Source Model 2020 (EFSM20), which was one of the primary input datasets of the European Seismic Hazard Model 2020, was entirely based on reusable data from existing active fault regional compilations. As scientific research on identifying and characterizing active faults progresses, the systematization and distribution of such research outputs should keep pace with the most recent technical developments in data distribution and usage.
The aim of this meeting is to identify the future perspectives of seismogenic fault databases at various scales, analyze their user needs (e.g., earthquake hazard analysts), and discuss how to tackle the challenges ahead of us.

In the context of space-borne geodetic techniques, Differential Synthetic Aperture Radar Interferometry (DInSAR) has demonstrated its efficacy in measuring surface displacements in different conditions and deformation scenarios. In particular, the advanced DInSAR method referred to as Parallel Small BAseline Subset (P-SBAS), developed by IREA-CNR, has emerged as particularly suitable to effectively and efficiently investigate the temporal evolution of surface displacements both in natural and anthropogenic hazard contexts. We refer to volcanoes, earthquakes, landslides, or human-induced deformation like subsidence from fluid exploitation, mining activities, and the construction of large infrastructures.

The P-SBAS algorithm has been released as an on-demand web-based tool by integrating it within the EarthConsole® platform and currently contributes to the on-demand remote sensing component of the EPOSAR service. In particular, EarthConsole® is a cloud-based platform supporting the scientific community with the development, testing, and hosting of their processing applications to enable Earth observation data exploitation and processing services. Nevertheless, the P-SBAS processing capability is still available through EPOSAR, the processing service developed by IREA-CNR, also accessible in the framework of the European Plate Observing System (EPOS) Satellite community, that provides systematic ground displacement products of several areas on Earth.

The herein presented on-demand P-SBAS tool enlarges the EPOSAR service portfolio and empowers users to seamlessly generate surface displacement maps and time series exploiting C-band satellite data. In particular the P-SBAS service allows the scientific users to process both Sentinel-1 and ENVISAT SAR images in fully autonomous manner, through a user-friendly web graphical interface which permits them to follow the progress of the processing tasks and avoids the need of data download on their own processing and archiving facilities.

The presented on-demand P-SBAS/EarthConsole® processing service will be accessible for the scientific community through the Network of Resources (NoR). In particular, the NoR is an ESA initiative that, among several missions, sponsors the scientific users to exploit commercial platform resources and services in the Earth Observation field, like EarthConsole®.

The training course has been designed to be a hands-on session structured in three main modules:

1. Overview on the Advanced DInSAR technique with a focus on the P-SBAS algorithm for obtaining displacement time series and corresponding mean deformation velocity maps;

2. Introduction to the EarthConsole® platform and its processing environment;

3. Presentation of the on-demand P-SBAS/EarthConsole® service for C-band satellite data interferometric processing focused on the Sentinel-1 platform, with also a brief overview on the ENVISAT one.

This meeting follows on from the meeting held at EGU 2023 with the intention of continuing discussions on common challenges and progressing opportunities for co-development to address specific issues.

Agenda will focus on next steps, tangible coordinated actions, and engaging with other relevant initiatives.

This splinter meeting is for members of the WCRP Regional Information for Society (RIfS) Scientific Steering Group, and the CORDEX Science Advisory Team who are present at EGU to share information, brainstorm, and consider opportunities to integrate activities with aligned purpose. RIfS is a relatively new project that is still being structured, and CORDEX is a well-established effort with a long history and the largest network under the RIfS umbrella. This will be an opportunity to co-produce some potential next steps and align on vision and ways of structuring collaborations across themes. In particular we wish to coordinate on themes that have broader reach than the individual CORDEX regions. We will briefly summarize some of the activities that are planned this year. We also will brainstorm ways to incorporate the experiences from across the CORDEX regions with other efforts to produce regional information for society. For example, we may discuss ways to piggyback additional elem ents on existing CORDEX activities, or develop activities that address common barriers and challenges across different regions. This is an open discussion for these committee members to bring up anything of interest, and also to get to know one-another better. Other WCRP project leads are welcome to attend.

The international initiatives CATCH, PACES, BEPSII, ASPeCt and QUiesCENT will hold a joint meeting bringing together scientists with an interest in atmosphere-ice-ocean research focussing on chemical, biogeochemical and physical processes in the Arctic and Antarctic and links to climate change. Cold regions which are seasonally or permanently covered by snow and ice, notably the Third Pole, are also of interest. The primary objective of this meeting is to strategize for the 5th International Polar Year 2032 planning workshop scheduled to take place in Aussois, Alps, France, in November 2024.

The Rock Glacier Inventories and Kinematics (RGIK) initiative invites all interested researchers to meet and discuss the current and future developments within the community. Potential discussion topics include amongst others rock glacier database, rock glacier velocity products, new research topics in the field of rock glaciers, etc.

PEOPLE-ER is a European Space Agency supported research project to develop open Earth observation tools for ecosystem restoration assessment and monitoring. The PEOPLE-ER final project meeting will include presentation and discussion of the open spectral recovery tool for forest restoration monitoring, with use cases in Finland, Romania, and Canada.

The OneGeochemistry initiative is an international collaboration between organisations that support geochemistry capability and data accessibility. The initiative focuses on coordinating and consolidating global efforts in geochemical data standardisation in order to create a sustainable data infrastructure that guarantees persistent, machine readable access to the global wealth of FAIR geochemical data. OneGeochemistry has formed a Working Group as part of the International Science Council’s Committee on Data (CODATA) and invites the wider community to engage in the creation and publication of standard geochemical data formats and data gathering-creation-storage workflows. This Splinter Meeting is intended to provide updates on OneGeochemistry activities and offer a forum for engagement and discussion.

During this Town Hall, the OneGeochemistry initiative will give an update on activities and progress and invite feedback and suggestions from all disciplines. We invite you to join a discussion on how the community can best help and participate in the creation of geochemical data standards. Our goal is to broaden community awareness of and participation in the initiative, and to further learn from successful initiatives in other disciplines.

The AGU and EGU Hydrology communities are embarking on a project to co-develop discipline-specific data management guidance. In this splinter we will provide an update on the progress and next steps.

We invite all hydrologists or researchers in any discipline interested in supporting this work.

European FRIEND (EURO-FRIEND) is one of the eight regional groups of the FRIEND programme.
FRIEND (Flow Regimes from International Experimental and Network Data) is an international research programme within the framework of IHP. Its objective is to study the spatial and temporal variability of hydrological regimes on a European scale and in other regions outside Europe. Originally initiated in Northern Europe, FRIEND has developed into a worldwide network of similarly structured projects. Today about 140 countries in different parts of the world participate in this programme.

EURO-FRIEND has evolved into a well-developed network of hydrologists, who are implementing an active research programme within five scientific project groups:

Project 1: European Water Archive
Project 2: Low Flow and Drought
Project 3: Large-scale Variations in Hydrological Characteristics

During this meeting, we will review the latest advances of the group, identify emerging challenges, and discuss potential funding sources (research grant, PhD, etc...).

This meeting is open to existing members of the EURO-FRIEND Project-3 and scientists from diverse disciplines wishing to join our discussion (and the group).

The correct measurement and availability of soil moisture data is crucial for the assessment of plant available water and the separation of energy and water fluxes on the land surface. Furthermore, in situ soil moisture data is used as “ground truth” to improve soil moisture model or satellite data products in many disciplines and communities, like climate and environmental sciences, hydrology, meteorology, agricultural engineering, decision making, disaster risk assessment and management. Although, in situ measurement error sources are well understood, there are still many unknowns concerning the uncertainties and their magnitudes that need to be considered when using in situ soil moisture data as a reference.

The collection, harmonization and quality control of freely available in situ soil moisture is the main mission of the International Soil Moisture Network (ISMN). In the last decade data from more than 77 networks (~3000 stations, ~12000 time series) covering the time period from 1952 until near real time were collected by the ISMN. This extensive database enables us to take the next important steps towards reliable model and satellite soil moisture product validation: identifying error sources of in situ soil moisture measurements, and calculating the uncertainty budgets of individual soil moisture sensors. For this purpose, ESA`s “Fiducial Reference Measurement for Soil Moisture” (FRM4SM) project and EURAMET`s “Soil Moisture Metrology” (SoMMet) Green Deal project were initiated in 2021 and 2022, respectively. All three initiatives—ISMN, FRM4SM, and SoMMet—are interdisciplinary collaborations that bring together a number of scientific communities to tackle data availabil ity and the deeper understanding of the soil moisture measurement, e.g., remote sensing, metrology, soil science, hydrology, and sensor production.

Within this splinter meeting, we want to take the opportunity to facilitate a lively discussion between soil moisture enthusiasts, users, data providers, and sensor manufacturers that are interested in the assessment of in situ soil moisture and their uncertainties. Our goal is to get a better understanding of:

· data availability, usage, and quality control · influences and error sources that drive the in situ soil moisture component, · challenges currently faced (e.g., missing standards to derive reliable data, etc.) · what we are still missing (e.g., stations at certain locations, etc.) in order to answer the questions: (1) what are the error sources; and (2) how can we derive a traceable uncertainty budget.

If you are working with in situ soil moisture probes, calibration, installation, or data, you are very welcome to join this open discussion round, organized by the FRM4SM, SoMMet, and ISMN project teams.

Natural gas hydrates are ice-like solids that form at low temperatures under increased pressure and are widespread in permafrost regions. As they predominantly contain climate-active methane as gas molecules and their stability is endangered by the global warming, there is a risk of a self-reinforcing process: permafrost and gas hydrates decompose due to global warming, methane gas is released into the atmosphere, which in turn increases the greenhouse effect. As the local geological, geophysical, geochemical and biological boundary conditions have a considerable influence on the decomposition process of the gas hydrates, an interdisciplinary approach is required in order to understand the complex problem. The Splinter meeting will provide an opportunity for all interested scientists to discuss how these issues can be addressed as part of an international collaboration and to discuss possible initial concrete steps.

The ESA's Climate Change Initiative for Soil Moisture data record is reaching in Spring 2024 its 9th version, providing a wealth of satellite based observations spanning over 4 decades aimed at improving our Climate System understanding.

This workshop wants to bring together the product development team and its user base, with the goal of shaping new product specifications tailored to the needs of the climate community.

The workshop participants will have a chance to learn more about the ESA CCI SM products---including their latest development and applications---, to provide guided feedback during the interactive session, and to participate in the open community discussion.

Join us if you have experience with the initiative and would like to contribute, or if you wish to use or simply improve your understanding of the data!

Global climate change mitigation and adaptation efforts remain largely inadequate, leading to a significant increase in climate-related lawsuits. This open splinter meeting offers geoscientists interested in climate change litigation a chance to engage with peers and legal scholars. The goal is to facilitate discussions, exchange ideas, and enhance mutual understanding of how the collaboration between science and law can develop to serve society in the best possible way.

This splinter meeting invites all interested scientists to discuss how we can bring controlled/active source seismic data to the EPOS.
EPOS, the European Plate Observing System, is a multidisciplinary, distributed research infrastructure that facilitates the integrated use of data, data products, and facilities from the solid Earth science community in Europe. The EPOS Data Portal is a virtual platform where FAIR principles are put into practice, enabling access to data and products from more than 250 scientific data services across Europe. Data and data services provided by EPOS are defined in a bottom-up approach by the experts in the respective thematic communities. Organised as Thematic Core Services, these communities are also responsible for providing their data and data services to EPOS.

Seismic data are key to understanding the structure and composition of the lithosphere at different scales. However, seismic data are not available through EPOS, the only European research infrastructure for solid Earth sciences. Primarily, because EPOS is still lacking the support of a dedicated community. This splinter meeting is a community-building effort that reaches out to all colleagues who regard themselves as part of the wider controlled/active source seismics community, both data producers and data consumers. We want to inform about EPOS in general and propose options for the community to get involved.

The meeting is devoted to the evaluation the TCS services and the assessment of the participation to the EC Projects

This splinter meeting is the first working group meeting of the newly founded IAG Joint Working Group (IAG JWG) in January 2024 under the umbrella of the Inter-Commission Committee on Geodesy for Climate Research (ICCC). Our mission is aimed at researchers interested in using Global Navigation Satellite System (GNSS) sensors for mass-market (or low-cost) climate and environmental monitoring to redefine methods to enable reliable measurements. In addition to precise positioning, we are researching the determination of important variables such as the water equivalent of snow and the water vapour content of the atmosphere. Being a global initiative, our aim is to overcome technological boundaries and promote international co-operation to tackle the challenges of climate change. All researchers interested in the use of small-scale GNSS sensors for climate monitoring and research are cordially invited to join.

Within the framework of European Space Agency (ESA) Climate Change Initiative, the High Resolution (HR) Land Cover (LC) Essential Climate Variable (ECV) project presents their products generated at Phase 1. The HRLC team presents the project products and some examples for the historical and the static maps, the LC change maps and the additional quality layers. We are very interested in your feedbak for the improvements on phase 2. More info at https://climate.esa.int/en/projects/high-resolution-land-cover/

With this splinter meeting, which is open for everyone, we would like to have a discussion on how to conduct scientific expeditions in remote and inaccessible areas more effectively.

Since these regions are not easy to reach, it can be difficult to find the means and infrastructure to reach those areas. It is important that the scientific community collaborates together where possible and with this splinter meeting we hope to bring together scientists that have an interest in scientific expeditions in remote and inaccessible areas.

We would like to discuss:
- ongoing initiatives
- potential new collaborations
- type of infrastructure needed
- practical aspects of such expeditions.

The organisers are mainly involved with offshore Arctic and Antarctic regions, but the discussions during this session are not limited to these geographical regions.

There is still a gap in quantifying future water availability when considering (weather) forecasting on one hand side and climate projections on the other. Apart from (sub-s)seasonal predictions, near-term (annual to decadal) climate predictions might help to shed light on a period that is relevant for decision-making. This, however, also requires the involvement of local stakeholders to figure out what needs they have and how to best possibly communicate uncertainties involved in this kind of predictions.

This splinter meeting brings together people interested in the working group "Near-term (annual to decadal) forecasts of water availability" (which is part of Theme 2: Holistic Solutions for water in the framework of the IAHS HELPING initiative). The main idea of this session is to give any interested person the chance to get in touch with this working group just to get informed or to actively participate in its activities like plans on papers or project joined applications.

https://iahs.info/Initiatives/Topic-for-the-Next-IAHS-decade/helping-working-groups/near-term-annual-to-decadal-forecasts-of-water-availability/

The stable isotopic composition of seawater and the carbon isotopic composition of dissolved inorganic carbon are essential ocean tracers that have been widely measured since the 1960s. They are in particular used to investigate the hydrological cycle and the exchanges between the ocean with , sea ice, ice sheets, the atmosphere and continental runoffs, as well as the bio-geochemical cycles, the anthropogenic carbon penetration, and the associated acidification of the oceans. Moreover, they are used to validate proxy-tracers measured in natural archives for reconstructing past climate evolution. Modeling studies suggest that the isotopes are currently experiencing large changes linked to global warming and the associated changes in the hydrological and biogeochemical cycles. However, using and interpreting current data sets is often hampered by substantial issues in data collection/measurement, validation, analysis, and synthesis, as well as in their interpretation.

This splinter session is aimed at sharing your experience with such data, whether you are data producers or data users, and discuss what could be done to improve the situation. You are welcome to come with a few slides on a USB key to provide material for discussion. We should in particular discuss the next steps, such as setting a working groups and meetings, maybe also a web site to further share our experience, reports, papers, venues... exchanging water samples or reference materials...

ESMValTool is an open-source software package that is developed internationally with many different institutions and researchers contributing. In this splinter meeting we would like to bring the ESMValTool user/developer community attending EGU together to discuss new developments and ideas.

The focus of this meeting will be on showcasing the innovative approaches and findings of the EIFFEL project in utilizing nature-based solutions (NbS) to address climate change challenges. This session aims to highlight the project's efforts in leveraging Earth Observation (EO) technologies, advanced analytics, and data integration tools to understand, monitor, and enhance the efficacy of nature-based interventions.

Participants will explore how the Pilot Applications & EIFFEL Horizontal Tools Suite supports the design, implementation, and evaluation of NbS by providing key insights into ecosystem services, biodiversity, and the socio-economic benefits of such solutions. The session will feature presentations on successful case studies, methodologies for assessing NbS impacts, and discussions on integrating these solutions into climate adaptation strategies.

The splinter meeting will serve as an opportunity for researchers, policymakers, practitioners, and stakeholders to engage in knowledge exchange, discuss challenges and opportunities, and foster collaborations for advancing the use of NbS in climate change adaptation. Through this session, the EIFFEL project aims to contribute to the broader discourse on sustainable, resilient, and inclusive approaches to climate adaptation, in line with global sustainability goals and the European Green Deal.

The Group on Earth Observations (GEO) is currently formulating its post-2025 Implementation Plan to serve its new Strategy. The paradigm of Earth Intelligence is prominent therein, among others calling for integration of earth, social sciences and new technologies (incl. Artificial Intelligence-AI, Machine Learning-ML etc), combining different scales and sectors and with special emphasis on user needs. Despite the fact that AI is expected to further thrust the design of services that provide Earth intelligence, there are also other ways to facilitate the use and experience of EO. The meeting aims at presenting what was implemented in this direction over the past 3 years by the H2020 EIFFEL project, how the different aspects of AI came into play and to discuss potential AI routes for the GEO community to pursue over the next years.

The first part of the session will comprise brief presentations on the EIFFEL pilots which utilized GEO infrastructure, such as GEOSS Platform (GEO DAB+ GEO Portal), GEOSS datasets and socio-economic data in unison with local authorities to build diverse climate change applications. These applications culminated in GEO Knowledge Hub entries, available to a much wider pool of potential users. One of the objectives is to identify how this process, i.e. an H2020 project contributing to the GKH, can be mainstreamed.

The second part revolves around the different aspects of AI touched upon during EIFFEL. A Large Language Model (LLM) was fine-tuned based on a compiled, expansive corpus, and utilised for the GEO Infrastructure search and metadata augmentation. The developments of the GEOSS Platform Plus (GPP) and EIFFEL projects based on this work will be presented. The training corpus was further utilised by the Knowledge Centre on Earth Observation (KCEO) to enhance semantic search in a variety of databases (including CORDIS and Copernicus). Further AI aspects include of course data processing but also explainable AI (XAI), a cornerstone in creating trustworthy information. The second, and major objective, will therefore be to map these AI elements against the GEO Strategy’s Earth Intelligence paradigm and respond to the growing needs coming from the GEO community.

Participants, including members from EIFFEL, GPP, GEO, EuroGEO and the KCEO will discuss how the above know-how can accommodate the rapidly evolving AI landscape to the benefit of GEO and Earth Intelligence.

Agenda:

-Introduction, scope (5mins)
-EIFFEL climate change Pilots, using the GEO infrastructure in unison with local stakeholders (8mins)
-GKH, paving the way for other Horizon projects (8mins)
-The EIFFEL Large Language model and the GPP (8mins)
-LLM co-benefits and other AI aspects (8mins)
-Open Discussion including (60mins):
• Mainstreaming GKH for Horizon projects.
• A generalised “GEO” LLM.
• Articulate a first response to the GEO AI foreseen activities.

This splinter meeting offers an opportunity to discuss and learn about the International Generic Sample Number IGSN and how it can help improve use and utility of physical samples and the data generated by their study. Using the IGSN to identify and cite a sample throughout its life from collection to laboratory to sample archive not only ensures that the sample and the data can be located and linked, but also that the people involved in the collection, analysis, and curation of a sample get the appropriate credit.

OpenAQ invites folks working with air quality data to an informal gathering. This is an opportunity to spend time with fellow air quality enthusiasts and share stories. OpenAQ is an NGO that aggregates open air quality data from across the globe onto an open-source data platform so that anyone concerned about air quality has unfettered access to the data they need to analyze, communicate and advocate for clean air.

Meeting between the EGU Pride group, APECS Germany, Rainbow Geosciences and GayGU to share ideas and future plans on how to better promote inclusion of LBTQIA+ people at all career stages in the geosciences.

This splinter meeting will host discussions on the latest results of the physical properties of the martian moons, their origin, and their comparison to other dark primitive populations of small bodies in the Solar System.
This meeting aims bringing together scientists from different backgrounds (spectroscopists, geologists, geophysicists, meteoritisists, dynamicists) and forge a network of collaborations in the era of space exploration for such primitive objects at different locations in our Solar System (Martian Moon eXplorations, Juice, UAE mission to main belt asteroids).

This splinter meeting intends to bring the outer solar system community together to showcase the current understanding of giant planets and their moons. This includes discussing the discoveries made by Juno, Cassini and ground-based studies and putting them in context of the forthcoming missions to Jupiter (Juice, Europa Clipper) and Uranus (Uranus Orbiter and Probe).

Here, we build on the momentum we achieved at the Town Hall Meeting (TM19) Common Grounds between the Global South and North. In this discussion, we ask: What cultural and professional perils and barriers exist that mitigate political discussions at conferences? How are colleagues from under-represented nations discouraged by some EDI initiatives? What are some examples of successful EDI? How can Global South scientists feel more invited at EGU?

Electron Backscatter Diffraction routinely yields large datasets for use in microstructural and microchemical investigations. Lattice distortions can be characterised and used to extract information on geometrically necessary dislocation densities and types. There are several approaches to this and one is the weighted Burgers vector approach. The splinter meeting will allow for discussion of the approach, with hands-on usage of code to show how it works and how it assists in microstructural investigations.

Earth Observation can contribute to disaster mitigation in many ways: from estimating risk through providing early warnings of events and timely information to responders to assessing damage and follow up activities. Sentinel data are particularly relevant in this context due to their high quality, regular acquisitions, and open data access model. This meeting will connect data users, service providers and scientists to discuss the use of Sentinel data infrastructures, processing algorithms and visualization tools relevant for disaster response and monitoring. Additionally, participants will have the opportunity to engage in hands-on tooling in Jupyterlab environment.
The Copernicus Data Space Ecosystem is a public service intended to highlight the capabilities of the Ecosystem for the processing of the Copernicus Sentinel data using the free and open, public interfaces and application programming interfaces. The Copernicus Data Space Ecosystem is placed as the primary access point for public space data. The integration of earth observation data from space in many environmental and earth system applications has great potential for the benefit of society and the use of public funded satellite programmes (through the European Union and European Space Agency).

Earth Observation plays a crucial role in mitigating disasters by providing risk estimates, early warnings, and essential information for responders. Moreover, beyond monitoring land-based situations, it's also a valuable tool for understanding atmospheric conditions. Sentinel data, known for high quality and an open data access model, are essential for these Earth Observation tasks. Similarly, the Streamlined Data Access API available in the ecosystem, including openEO, provides a suite of tools and services to support data processing and analysis.

Therefore, in this session, we aim to bring together data users, service providers, and scientists interested in analyzing these collections with this novel approach(openEO). By adopting openEO, developers, researchers, and data scientists gain access to a unified and interoperable platform, empowering them to harness distributed computing environments and leverage cloud-based resources for addressing complex geospatial challenges. Thus, we'll delve into utilizing the openEO API within the Copernicus Data Space Ecosystem for analyzing Sentinel data, with a specific focus on Disaster and Atmospheric Monitoring. Additionally, users will be guided in utilizing the freely available JupyterLab environment provided by the ecosystem.

Following the last years sprinter at EGU23, "Heliophysics in Europe" workshop at ESTEC last autumn, and PS3.1 session, we continue discussion how to build a common community covering the Solar Terrestrial and Solar Planetary plasma physics (corresponding to EGU ST division and PS division, respectively). We summarize what has beed proceeded and what to be done toward and during the next "Heliophysics in Europe" workshop at ESTEC in November.
The motivation of this activity following: Solar Terrestrial and Solar Planetary plasma physics have common fundamental physics with the same scientists working on both subjects, and hence called as Heliophysics in NASA/ESA terminology. However, no solid community nor even email list does not exist to cover this Heliophysic field i Europe, making communication between European heliophysics scientists even between nearby sub-field. This is large disadvantage in forming teams aimed for missions (e.g. ESA) and large projects (e.g., EU funding).

This networking event, organised by APECS, invites ECRs from across the polar community to come along and meet your fellow colleagues. A short presentation by the APECS ExCom will be followed by speed dating as a way to get to know one another.

Discussion on current state and next steps of coupling of ice sheet models to Earth System components, especially ocean and subglacial hydrology.

This can include technical aspects such as handling asynchonicity and approaches for initialising the coupled model system.

Discussion of the newly published Marine Ice Sheet - Ocean Model Intercomparson Project phase 2 (MISOMIP2) protocol.

The MOXXI Working Group has the task to “promote the advancement of novel observational techniques that lead to new sources of information to help better understand the hydrological cycle”. The meeting will be used to plan initiatives and activities of the IAHS Working Group.

Background

There are an increasing number of models for which large ensembles (LEs) have been generated. This is important for assessing the role of internal climate variability in a changing climate and is also key to understanding responses in extreme weather and climate events. The first part of the meeting will provide the opportunity for short presentations on key issues and/or opportunities, followed by a brainstorming discussion session based around the below questions and aims. This meeting is part of the European Climate Research Alliance (ECRA) Polar Collaborative Programme.

Questions

With a range of LE datasets to choose from, the question of which may be more reliable arises.
• In general different models produce different characteristics in internal variability. Which ones are more accurate? Given the relatively short observational record and large internal climate variability of the polar regions this is a challenging question to answer.
• Which models are most appropriate for assessing extreme weather/climate events? What are the best practices for downscaling?


Aims

The specific aims of this splinter meeting are to:
1. Identify the opportunities and challenges in using LEs to study polar climate change.
2. Identify best practice for evaluating LEs for use in polar studies.
3. Identify strategies for ensuring future LEs are designed, where feasible, to be appropriate for use in studies of polar climate change.

EGU provides a unique opportunity for these different projects to get together in person to align their project work and collaborate. Ensuring impacts beyond the duration of the different projects.

Project meeting of the EU PARATUS project (https://www.paratus-project.eu/) for

Ice is omnipresent in our Solar System; on Earth, on planetary bodies, and on moons in the outer Solar System. In the past, terrestrial and extraterrestrial cryosphere science mostly developed as independent research fields whereas synergies may shed light on both fields. This ISSI Team brings together scientists working on terrestrial and extra-terrestrial cryospheres.

The main goal is to make knowledge hidden in the vast amounts of existing data from different research groups accessible by consolidating it into a comprehensive meta-data enriched compilation of ice properties. This extends to relevant physical regimes on both Earth, and icy moons including data from field campaign measurements, laboratory experiments, and planetary missions.

Information on thermal, physical, and chemical ice properties will be used to derive parametrizations (interpolations to express the dependence of properties on e.g., temperature, pressure or depth, and chemical composition). These can be easily implemented as initial and boundary conditions or sub-scale material parameters in numerical models, thereby significantly enhancing the data’s simulation readiness. At the end of the project, the database, the accompanying parametrizations, and potential simulation results will be made publicly available. This approach will provide us with the unique opportunity to transfer and extrapolate the information from the Earth to the outer Solar System bodies.

Our ISSI Team is an important step forward to bring together the Earth cryosphere community and the icy moons community to explore cryo-environments at different scales. With the launch of the JUICE mission this year and Europa Clipper mission in 2024, this research is timely and will lay the foundation for joint analyses between terrestrial and extra-terrestrial cryosphere communities to address future mission data from the outer Solar System.

In-person meeting for the Joint Body on the Status of Mountain Snow Cover (JB-SMSC) for all the attendees at EGU24. This Joint-Body is a collaboration between International Association of Cryospheric Sciences (IACS), the Mountain Research Initiative (MRI), and the WMO Global Cryosphere Watch (GCW).
In this meeting, we shall discuss progress and future activities on various topics related to the JB: global mountain inventory of in-situ snow observations, remote sensing climatological analysis, and more.
Members of the JB are welcome to attend as well as any other who are interested in this endeavor.

The Green Cluster on Cultural Heritage will bring together the European Research Executive Agency and the 'Climate Effects teams' which is comprised of 4 Horizon Europe projects to discuss on synergies to address the urgent need to protect monuments, historic buildings, and sites from the diverse impacts of climatic risks, natural and anthropogenic hazards.

This meeting is a follow-up to the EGU session CR1.3 “East and West Antarctica’s responses to climate change, past present and future” and aims to discuss the scientific gaps in understanding the sensitivity of the Antarctic ice sheet to short- and long-term climate and ocean variability.
Given the large uncertainties in current projections, there is an urgent need for more regional observations from both the West and East Antarctic Ice Sheets on the physical mechanisms driving processes and environmental change.
For example, despite their importance for understanding the instability of the ice sheet, the processes occurring below and at the termination of marine ice sheet or in the sea-ice and ice shelf covered areas are largely unknown as they are difficult to access and require large investments in field work and multidisciplinary efforts.
The 5th International Polar Year 2030-32 and its preparatory phase provide an opportunity to collaboratively conduct multinational campaigns to achieve high-priority scientific goals through the sharing of data, knowledge and cross-border access to infrastructure. This splinter meeting will allow the Antarctic Ice Sheet community to discuss priorities, inform ongoing projects and future plans, and develop further collaborations.

This meeting is intended to create awareness in the geoscience community and beyond that there is a demand for a coordinated effort to consolidate the Cenozoic Geological Time Scale. We want to discuss potential avenues to set up an international consortium to form a synchronised and highly accurate time frame for Earth Sciences spanning the last 100 million years.

The Tipping Point Modelling Intercomparison Project (www.tipmip.org) is an interdisciplinary model intercomparison project that aims to assess, among other things, the risk of crossing individual tipping points in the cryosphere, biosphere and core circulation systems at different levels of ongoing climate and land-use change. At this splinter meeting, we will provide updates to the community on the current status of TIPMIP, as well as to highlight the ways in which those interested in joining the project can get involved.

We would like to use the opportunity given by EGU to have a consortium meeting in person for the EJP Soil project ICONICA including all partners from Europe and New Zealand. ICONICA aims to identify optimal P fertilisation to underpin sustainable production and enhance nutrient efficiency for environmental sustainability giving farmers, land managers and society the necessary knowledge to manage their soils appropriately.

C9 is a Joint Working Group of the Inter-Commission Committee on Geodesy for Climate Research (ICCC) established to advance the use of geodetic observations for climate research. We propose to investigate the gain obtained by high-resolution (HR) altimetry 1-D and 2-D measurements, and to encourage innovative interdisciplinary research and applications in climate change studies.

I would like to invite all conveners, authors and members of the Hydrological Forecasting (HS4) sub-division to this meeting. This would be an excellent opportunity for early career scientists to network within the community. The meeting will be hybrid and information will be shared later. Please get in touch with the sub-division chair (Ilias Pechlivanidis) for more information. In this meeting, the chair of the sub-division will be passed to Louise Slater.

An IACS Working Group on the delineation of glaciers, ice sheets, and ice sheet basins has recently been created to help assess double- (or under-) counting of ice sheet and glacier mass loss due to different communities using non-aligned masks for their regions of interest.

This splinter meeting will be the first in-person meeting of this working group, where we will discuss initial steps and directions for the effort.

Content may well be king, but the value of presentation cannot be underestimated for ensuring that a scientific paper has an impact on its intended audience. This interactive session will provide tools for shaping a clear and coherent scientific narrative that conveys what motivated the research, how it was carried out, what was found, and why that is important. Once a paper is written, the next job is to get it published so that your findings reach an audience that is most likely to benefit from them. This is easier said than done given both the increasing volume of research and the ever-expanding landscape of scientific journals: it requires a strategic approach to publishing. The session will briefly discuss the choice of a journal and editorial expectations and processes. The workshop is suitable for researchers at all levels, but those early in their careers are especially welcome to attend. Feel free to bring along a paper that you are working on!

The meeting aims to gather scientists having interest on meteorological tsunamis or meteotsunamis, atmospherically-generated long-ocean waves in the tsunami frequency band, which is the topic of freshly started GLOMETS project (Global science of meteotsunamis: from planetary to mesoscale processes, https://stijena.krs.hr/~ivilibic/glomets/indexen.html). All researchers having interests in (1) meteotsunami and sea level observations at minute resolutions, (2) atmosphere-ocean modelling for meteotsunamis, (3) atmosphere-ocean interactions and ocean processes, (4) processes in the atmosphere generating meteotsunamis, (5) projecting meteotsunamis in future climates, (6) meteotsunamis forecasting and developing early warning system, (7) planetary meteotsunami waves generated by explosive volcanic eruptions, and other connected topics, are warmly welcomed to join the meeting.

This breakout session will introduce a new non-contact method for measuring streamflow using audible sound (see the reference at the bottom). The method addresses some of the issues with traditional stream gauging methods. The session will be divided into three parts:

(1) An introduction to acoustic sensing.

(2) During the interactive demonstration, participants will have the chance to listen to audio clips recorded in a real stream and measure the sound level using their smartphones with a sound level app, such as Decibel X. They will be able to create an acoustic rating curve (sound level vs. discharge) for the stream.

(3) The discussion section will cover potential collaboration opportunities, benefits for early adopters, research and applications in diverse field settings, and the potential for citizen science.

A collaborative project called GeoLUCA will be discussed in details by project partners and colleagues from the Alpine region and beyond.

The Ocean Virtual Laboratory (OVL) has been actively developed in the past 10 years and now offers a virtual platform to allow oceanographers to discover the existence and then to handle jointly, in a convenient, flexible and intuitive way, the various co-located EO and related model/in-situ datasets over dedicated regions of interest with a multifaceted point of view. Hands on tutorial, making use of the freely available online and standalone tools will be provided, going through a few typical case studies highlighting the potential of satellite earth observation for upper ocean dynamic analysis. The standalone tool tutorial will include the installation of SEAScope and the python bindings, to exploit the analysis capabilities using jupyter notebooks.

This meeting is to gather the InterRidge community at EGU, to discuss the activities of the InterRidge group worldwide and the reformation of it.

A meeting for anyone interested in Agrogeophysics to come and discuss the future of this discipline. After a very successful conference held in Zurich earlier this year, we want to take some time to let you know our future plans and get your impact. The main discussion point will be around the potential for a specal issue in Agrogeophysics.

The purpose of this brainstorming meeting is to discuss potential topics, ideas, and strategies for implementation and identify potential patterns for developing project (s) in response to Horizon Europe (HORIZON) 2024

HELPING, the new scientific decade of the International Association of Hydrological Sciences, aims to address the water crises communities across the world are facing, by combining process understanding at local and global scales, integrating new technologies, and co-creating knowledge. In all of this, communication is paramount, both within the scientific community (between hydrologists and scientists in other fields, working in different parts of the world, and at different scales) and outside of it (with stakeholders, decision-makers, and local communities). We aim to co-create a community paper to gain a broader understanding of communication and outreach strategies that can help achieve HELPING’s global goal, and engage different water-related stakeholders across the world. The paper also aims to reflect on strategies that have been leveraged by similar scientific initiatives, and lessons learned from previous scientific decades (Panta Rhei, PUB), as well as on the changes that science communication has undergone over the past few decades.

This is the first in-person/hybrid event to refine the vision for this paper (the "why"), and outline the questions (the "what") we want to address through the paper. We would also like to discuss the next conceptual and logistical steps towards the paper, and distribute responsibilities for the corresponding process (the "how"). The meeting agenda is tentatively an introduction to the overall idea, discussions within smaller groups on some seed questions about each objective, and a joint inter-group discussion to close out the session.

Come and say hola!

This splinter session aims at discussing some presently urgent issues identified for ground-based space weather observations, both for instrument networks and single instruments. Several common issues have been recognized in preceding discussions throughout the year 2023: in particular at the EGU n Vienna, during the Space Weather Coordination Summit in Geneve, and at the European Space Weather Week in Toulouse.

Such common issues include the need of coordinated and durable financial support for the maintenance and continued operation of such networks; their spatial densification and expansion, and a modernization to higher temporal resolution data, as required by the expressed future needs of space weather operations. The pending transition of such ground-based assets from best effort operations, traditionally serving mostly science needs, to 24/7 real time operations, serving future space weather needs, is another commonly raised item of concern.

Recently the question of available frequencies (and their protection) both for active radar-operations and passive observations of radio-emissions from the sun has been recognized as a high-priority discussion item. Ground based radar systems represent a highly valuable operational space weather entity , however, the security of their operational frequency ranges is not certain. At the same time, passive observations of solar emissions will require clean access to full “bands of frequencies”. In both cases, we start to see the case for increased frequency protection for the benefit of both SWx user- and science-communities alike.

The session will provide a brief overview of some of the above points for further discussion and will look to identify some common actions, including the formal entities to carry these actions forward.
