The H2020 I-CHANGE (https://ichange-project.eu/, 2021-2025) project is based on the idea that citizens and the civil society have a central role in the definition of environmental protection and climate action and that their direct involvement is essential to drive a true shift and promotion of behavioural changes towards more sustainable patterns. Therefore, I-CHANGE aims to raise awareness on the impacts of climate change and related natural hazards to enable behavioural change. This is intended to be reached by:
- Climate change awareness: knowledge of science and the understanding of physical, socio-economic and cultural processes;
- Active participation of citizens in data collection in eight Living Labs through citizen tools and sensors;
- Improvement of data usability and interoperability of the data which is collected by the citizens.

This meeting represents the final scientific event of the project with the presentation of the project final results and some invited keynote speakers.

The Digital Water Globe (DWG) of the International Association of Hydrological Sciences (IAHS) provides a new tool for scientists to share their research through a more interdisciplinary and transformative society. DWG is spatially contextualised within the framework of the Sustainable Development Goals (SDGs), the Unsolved Problems in Hydrology (UPHs), and the Scientific Decades of the IAHS: PUB (Prediction in Ungauged Basins), Panta Rhei and the current HELPING (Hydrologists Engaging Local People IN one Global world). For early-career scientists, the DWG is a great opportunity to increase the visibility of their research and forge new connections. Also, DWG’s users can create profiles free of charge and then log their articles, datasets and case studies. This meeting provides an introduction to the DWG for new users, as well as a presentation of showcase profiles and data entries. The meeting presentation will highlight the DWG’s purpose and key features. We will showcase existing profiles and data entries that demonstrate best practices and diverse applications of the DWG. In addition, there will be an attendees feedback session to gather insights into user experience, discuss specific aspects and needs of the tool, and further refine the tool.
Thus, this Session will also provide an overview of ongoing IAHS’s hydrological research activities as well as scientific achievements which can be highlighted through the DWG. Furthermore, we welcome novel insights, experiences and learnings to accelerate scientific collaboration through the DWG, thereby gathering similar topics or similar areas, and to facilitate engagement with stakeholders, partner organisations, and citizens.

The working group “Outreach, Communication and Promoting the Digital Water Globe” is part of the new Scientific Decade of IAHS: Hydrologists Engaging Local People IN one Global world (https://iahs.info/Initiatives/Scientific-Decades/HELPING/). This meeting is a check-in for the progress made on our working group strategy, including contributions to the communication guidelines and templates provided by HELPING, and the ongoing community paper on science communication. It will be an opportunity for working group members to provide feedback on the organisational framework and, if necessary, to finalise the article draft for publication in Hydrological Sciences Journal. Furthermore, it will be an opportunity for working group members to connect offline, rather than relying on online meetings. Finally, we offer the opportunity for new working group members to join the effort and catch them up to speed on our current activities.

The Working Group (WG) "Co-Creating Water Knowledge" of the HELPING Initiative of IAHS (https://iahs.info/Initiatives/Scientific-Decades/helping-working-groups/co-creating-water-knowledge/) 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 International Commission on Human-Water Feedbacks of the International Association of Hydrological Sciences (IAHS) focuses 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 SAPHEA project supports the integration of geothermal energy into multivalent District Heating and Cooling (DHC) networks by creating a single Digital Market Uptake Hub for GeoDHC.

At the heart of the Hub is the SAPHEA Tool, a GIS-based platform that integrates 10 pan-European datasets and calculation modules to estimate the estimated generation profile and levelized cost of heat from both deep geothermal and shallow. This tool builds on previous research outcomes, from the Geophires project and the Cost Action GeoDHC.

The Hub also offers a Knowledge Base & Literature Repository, Strategies & Guidelines, Data & Tools, and a Gamebook guiding users across these resources aimed to support early-stage investment decisions and strategic planning.

In this hands-on workshop, we will introduce the SAPHEA project, offer a live tour of the Digital Market Uptake Hub, and show a walk-through and practical application to local heating and cooling planning of the SAPHEA Tool. Attendees will see firsthand how these resources and tools can empower market actors (local authorities, community services, energy suppliers, and research and academia) to design and implement low-carbon geothermal development scenarios, ensuring lasting impact beyond the project's lifecycle.

When proposing new legislation, policymakers often open a public call for evidence! This allows individuals and institutions to provide information that is relevant to the topic so that it can be considered!

Open calls for evidence can take many forms - from informal discussions to formal online feedback forms. They are an excellent way for researchers to start engaging with policymaking as it enables them to understand the policy issues and questions!

Led by policy experts, this Splinter Meeting will provide participants with all the information that they need to provide evidence through various forms of these established mechanisms! It will also provide you with tips about how to frame your evidence so that it is used by policymakers.

Join experts who are working within political institutions to hear about how science is used by policymakers and how legislation is made. Experts will provide insights on the type of work that they undertake, how political institutions function, the type of scientific evidence that is most useful, their career progression, and how you can start engaging more effectively in the policymaking process!

This session invites participants to give short (5 minute) presentations of their 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 those presenting can improve when discussing your research with policymakers in the future. This will not only allow those involved and those in the audience to gain a better understanding of how to effectively present to policymakers but also highlight specific aspects of the presentation that are likely to resonate with the policy community moving forward! The panel will also provide feedback on the policy areas in which they believe the research presented could be relevant, including current and upcoming policies.

The panel will assess up to six scientists during this session. Timeslots will be allocated on a first-come, first-serve basis. You can already submit your topic for consideration here: https://www.egu.eu/forms/Pitching2Policy/

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!

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.

Iliad has implemented a series of thematic and local twins in Europe, Africa and the Middle East. Through the use of existing global resources such as Copernicus, EmodNet and national resources such as Barentswatch, digitalt twins of the ocean have been developed to solve societal challenges related to aquaculture, fisheries, water quality, renewable energy and more.

In this meeting Iliad invites you to selected demonstrations of digital twins followed by a discussion of next generation research and innovation needs to further develop digital twins.

The freshwater fluxes in the Artic waters, Nordic Seas and North Atlantic Ocean critically influence ocean stratification and water mass transformation. Changes in upper ocean density caused by the advection of cold and fresh Arctic water and warm and salty Atlantic water have a profound effect on convection in the North Atlantic. In addition, upper ocean stratification in the northern polar regions affect the interactions between ocean, sea and atmosphere in the Arctic Ocean influencing marine ecosystems.
The importance of these processes makes it essential to increase present understanding, enhance present observational capabilities and plan for future observational needs.
In this splinter meeting, we invite scientists and stakeholders working with freshwater fluxes, sources of freshwater (Greenland ice sheet, glaciers and Arctic rivers) and climatic and societal impacts to come together to discuss how satellite observations, in-situ measurements and models may contribute and develop in order to investigate the key processes that drive freshwater dynamics.

The Green Cluster on Cultural Heritage (TRIQUETRA, THETIDA, RescueME, STECCI Horizon Europe projects funded under topic HORIZON-CL2-2022-HERITAGE-01-08) will unite with the European Research Executive Agency to discuss on synergies to address the urgent need to protect monuments, historic buildings, and sites against the diverse impacts of climatic risks, natural and anthropogenic hazards.

We particularly invite (graduate) students to join the networking event.

In the last decades, disaster risk reduction and climate change adaptation have gained prominence in research and policy as the impact from climate change has become unavoidable. With this rise in prominence, our understanding of natural hazards risks evolved to not only encompass physical factors but also incorporate the social and behavioural aspects of vulnerability, presenting a significant opportunity to advance research on multi-hazard vulnerability.
Current studies often lack a holistic approach, focusing on single sectors or scale, but there is increased demand for more integrated, cross-sectoral, and transdisciplinary research. Expanding vulnerability assessments can lead to more comprehensive, adaptable solutions. Such approaches can improve adaptation strategies, address the root causes of vulnerability, and align with global goals such as the SDGs, NUA, and the Paris Agreement.
In this context, we aim at fostering integration by convening a Splinter Meeting to discuss the potential avenues for effective inter and transdisciplinary research on multi-hazard vulnerability, providing a platform for researchers and practitioners to share their experiences, outline advances and gaps, and chart a collaborative research agenda. The meeting will be organized in a participatory format to encourage discussion on key topics, including sources of uncertainty in vulnerability assessments, mixed methods applications, data integration (including EO-based data), multi-sectoral approaches, the role of spatial and temporal scales, and interdisciplinary and transdisciplinary methods.
Expected outcomes include mapping existing contributions and locating the clusters and the blind spots of existing research. The results will be made publicly available to enable a more focused and informed approach to future research.

Effective stakeholder engagement is a cornerstone of successful risk communication. This splinter meeting will focus on innovative methods for involving stakeholders in disaster risk management, including interactive games, science-policy interfaces, and other (creative) participatory practices. Participants will explore various approaches for engaging diverse audiences, enhancing their understanding of risk information, and highlighting different co-creation and knowledge co-production processes. The meeting will provide a platform for sharing experiences and strategies for designing and implementing stakeholder engagement activities that promote mutual feedback and transdisciplinary collaboration. Contributing to the European Commission’s disaster resilience goal no. 2 on ‘Prepare - Increasing risk awareness and preparedness of the population’ and the preparEU programme, this session aims to foster creative solutions and strengthen stakeholder relationships in the context of disaster risk reduction. Attendees are encouraged to participate in the scientific session and short course, which together with this meeting form a unified path for a deeper exploration of risk communication and engagement strategies.

Misinformation poses a significant challenge to effective risk communication, often undermining public trust and response. This splinter meeting will address the complexities of managing misinformation in the context of disaster risk communication. Participants will discuss strategies for identifying, countering, and mitigating misinformation, as well as the impact of cognitive biases and media influence on public perception of risk. The meeting will offer insights into best practices for maintaining accurate and credible communication amidst a landscape of conflicting information. Reflecting on the European Commission’s disaster resilience goal no. 2 on ‘Prepare - Increasing risk awareness and preparedness of the population’ and the preparEU programme, this session aims to enhance participants' ability to navigate and address misinformation, ensuring more reliable and effective risk communication. Attendees are encouraged to engage in the scientific session and short course, which together with this meeting form a unified path for a thorough examination of risk communication challenges and solutions.

The session invites practitioners and (social) scientists working in Horizon Disaster Resilient Societies (DRS) projects to exchange experiences and lessons around risk communication.

The splinter meeting will provide a dynamic platform for sharing experiences, networking, and brainstorming within the realm of transdisciplinary research. This interactive forum is designed to facilitate meaningful exchanges among researchers, practitioners, and stakeholders involved in disaster risk reduction and multi-risk management. Drawing on the experiences of European projects such as The HuT (https://thehut-nexus.eu), PARATUS (https://www.paratus-project.eu), MYRIAD (https://www.myriadproject.eu), and DIRECTED (https://directedproject.eu), participants will explore effective strategies for fostering collaboration across diverse fields, identify emerging challenges, and develop innovative approaches to complex problems. The meeting aims to strengthen connections within the transdisciplinary research community and generate new ideas for advancing disaster resilience and risk management. Participants are encouraged to join the scientific session and short course, which together with this meeting form a unified path, allowing them to engage in the entire programme or select specific parts based on their interests.

We warmly invite all FRIEND-Water programme members and those interested in joining our vibrant network to attend, contribute ideas, and shape the future of this international collaboration.

This is a joint meeting of the ILP East Antarctica, and SCAR Expert Group AGE and the INSTANT Solid Earth - Ice Interactions Theme. We will present the current status of these initiatives and discuss cross-links between them.

This meeting aims to bring together researchers working on (multi-)hazard disaster risk recovery to foster collaboration and discussion. Currently, there is no dedicated space at EGU for researchers from different backgrounds to connect on this topic. Disaster risk studies often remain static, with limited focus on recovery dynamics over time.

This session provides an opportunity to share insights into state-of-the-art recovery research, discuss methodological challenges, and explore potential collaborations. Participants are invited to exchange ideas on advancing disaster risk recovery research in the coming years.

The meeting will discuss the initiation of a new Research Program under SCAR (Scientific Committee of Antarctic Research) on Earth's last frontier, Antarctica. Anarctica contains about 10% of the planet's most cryptic continental crust. Understanding this continent in depth is crucial for revealing interactions between the Solid Earth, Cryosphere, Ocean, Hydrology, Atmosphere, and Biosphere, and their global impacts. Recent SCAR groups have shown that Antarctica's continental lithosphere is much more complex than previously thought, with significant variabilities affecting geothermal heat flow and ice dynamics. AGE aims to advance our understanding of Antarctica’s geological features and heterogeneities and how these have shaped Antarctica over time. Three task groups will address and integrate innovative methods, data sets, and models to better reveal Antarctica’s Architecture, the Processes that led to its formation, and the Interactions it triggers. AGE aims specifically to collect and integrate critical new geological and geophysical data in key areas to fill knowledge gaps and promote new geoscience projects, also in preparation for the 5th International Polar Year 2032/33. Any interested geoscientist is invited to participate and to contribute to the planning of the research program.

Safety of Nuclear Waste Disposal (SaND) is a new online open access journal covering all aspects of nuclear waste disposal: natural science, engineering and humanities. As a public peer review journal, it guarantees full transparency in the publishing process – transparency is a key issue for building trust in nuclear waste disposal and in the authorities involved in the process.
Of course, as a new journal SaND does not yet have an impact factor. Consequently, we want to popularize the journal and have to show potential authors that it is worth publishing in SaND. The main merit of publishing in SaND is that it is the first journal dedicated specifically to issues surrounding nuclear waste management, including interim storage and final disposal. Another advantage is the individual and fast editorial handling of the manuscripts, the public peer review process and the open access character of the journal, i.e. the typical amenities of all Copernicus journals.
Therefore, we want to hold a splinter meeting at the upcoming EGU 2025 aiming at the participants of all those sessions dealing with nuclear waste disposal and also its related topics.
At the meeting we are going to present:
• The short history of SaND from the first two abstract volumes of the safeND conferences in 2021 and 2023 to the currently growing paper collection “Trust in models” and the upcoming social science paper collection “The power of the mundane in nuclear energy cultures” plus an envisaged volume on post closure safety.
• Our plan to develop SaND from abstract volumes via paper collections to a scientific journal with a good reputation within the multidisciplinary nuclear waste disposal community.
• The managing editorial board with members from different disciplines such as biosciences, geosciences and social sciences and their commitment to efficient publishing and careful paper handling.
• The advantages of publishing in a public peer review open access journal which is focused on one topic, but highlights all multidisciplinary facets of it.
The one-hour meeting will will consist of a half an hour presentation (featuring the bullet points from above) held by select members of the managing editorial Board of SaND, followed by another half an hour time for questions from the audience and discussions with all attendees.
We hope to find:
• new authors for a new paper collection with contributions from the nuclear waste disposal sessions at EGU 2025
• scientists willing to send in manuscripts irrespective of any topically-focused SaND volume.

The Global Ecosystem Research Infrastructure (GERI) is composed of six large environmental research infrastructures: SAEON/South Africa, TERN/Australia, CERN/China, NEON/USA, ICOS/Europe, eLTER/Europe). With funding from a U.S. National Science Foundation AccelNet award, we have assembled a global network of early career researchers (ECRs) from GERI and other networks to develop, distribute, analyze, and publish a global survey. This Splinter Meeting Session will focus on the methods, approach, and preliminary results from the ECR survey done by the U.S. NSF funded AccelNet team. We will also engage potential new survey participants, solicit feedback, and discuss next steps to grow the membership and utility of the ECR Group. Additionally, this Splinter Meeting Session will provide a venue for the ECR working group participants to network and collaborate in person for the first time. The ECR survey aims to better understand several key areas, which will be points of discussion during this splinter meeting:

Background Questions: Collects demographic and professional details to understand participants' academic and career contexts.
Research Infrastructure (RI) and Network Questions: Explores experiences with RIs like NEON and TERN or other networks, focusing on communication, participation barriers, and career impacts.
Training Questions: Reviews training adequacy, additional skills needed, mentoring roles, and skill importance in research.
Global Research Questions: Assesses the perceived value of global collaboration, identifying benefits and challenges.
Demographics: Gathers personal demographic data to profile survey participants' diversity.

Earth sciences like Hydrogeology and Hydrology deal with freshwater, the most significant share of the global water cycle for humanity. However, hydrology and groundwater education require a high degree of abstraction and a large variety of competencies, ranging from applied field and laboratory methods to quantitative analysis involving advanced mathematical and physical concepts. With a general tendency towards digitalization and media-enriched learning, hydrology and groundwater related education is rapidly evolving a large pool of innovative methods and didactics, such as interactive documents, videos, and electronic questions for various assessments. Combined with a philosophy of openness and accessibility, the quality and outreach of hydrology and groundwater education can be enhanced.
The meeting aims to transfer and provide applied knowledge about recent and innovative advances in hydrology and groundwater education. We will introduce methods and workflows in a practical way so that attendees can easily incorporate them into their own teaching. The methods and materials that the workshop will cover comprise, for example, (1) interactive documents based on Python, (2) electronic assessments with different platforms for classroom- and individual use, (3) instructional videos ranging from screencasts to laboratory and field demonstrations, (4) implementation of measured real-world field data for applied education, and more. The participants will gain experience by practicing and using the methods, tools, and materials with selected examples. Subsequently, attendees will be able to implement the available open-source materials in their own education activities.

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.

Several Arctic-focused projects are underway for better understanding the sources and impacts of short-lived climate forcers, such as aerosols, methane, and tropospheric ozone. These include the HTAP Fires multi-model project and the methane focused Reduc(h4)e project, among others, with deliverables planned between 2025 and 2027. The splinter meeting at EGU would allow modellers and other interested parties to meet to discuss the input datasets, modelling setup, progress, and challenges, and for participants to show some initial results and analysis. This meeting would facilitate collaboration and exchange of ideas for the success of these projects. This meeting may also result in more groups participating with their models.

Research often starts with the spark of an idea, but we spend most of our research time with the challenges that follow. In Earth Science research, these include
1) methodological dead-ends, a lack of theory or knowledge,
2) problems of temporal and spatial scaling and extrapolation,
3) restricted access to field sites or data, or
4) everyday hurdles of life as a scientist.

With this meeting, we address some of those 'problems'. In discussing challenges among our diverse disciplines and backgrounds, we seek to find possible solutions, suggest new research approaches and methods, and encourage further networking.

The session kicks off with brief "elevator pitch" presentations of three to four selected key issues. These challenges are then explored in depth during breakout group discussions, which will be guided by lead questions. Whether you bring expert knowledge or a fresh viewpoint from your background, your insight can help us all see problems from a new angle. We present the solutions and suggestions from each breakout group in a final discussion with all participants.

How can you take part?
If you have a problem you'd like to see addressed, send us a short description (3-4 sentences) by March 1st, 2025.
And otherwise, join the meeting! No need to come with a problem, simply join the discussion, engage with fellow scientists, expand your disciplinary horizon and help us solve some problems together.

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-) 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.

Vertical profile measurements in the Arctic are critical for understanding rapidly changing sources of trace gas and aerosol, their impacts on clouds and climate forcing, and constraining Arctic numerical weather prediction. However, there is a severe lack of regular vertical information on meteorological parameters and trace constituents in the Arctic atmosphere, particularly lacking information on seasonality and variability across different Arctic regions. I preparation for the next International Polar Year (IPY) 2032-3, the Arctic research community is aiming to build capacity for a new programme of regular trace gas and aerosol profile measurements from airborne and remote sensing platforms in the Arctic. This ambitious programme aims to deliver a transformative enhancement in the coverage of regular vertical sampling across the Arctic region. This splinter meeting will present and discuss ideas for measurements, platforms, and the motivation behind implementing this programme.

A group of European researchers has recently submitted a project proposal to the EU-COST networks, aiming to establish a long-lasting European network dedicated to advancing research and fostering exchanges on climate resilience.

Annual internal meeting of the CatchNet (Catchment transport and Cryo-hydrology Network) extended core group

OneGeochemistry is a CODATA Working Group established to advance geoscientific knowledge and discoveries by building and maintaining consensus-driven standards that make geochemistry research data globally Findable, Accessible, and truly Interoperable and Reusable (FAIR) for both humans and machines. OneGeochemistry aims to establish a global network of interoperable geochemical data resources to maximise the impact of investment into laboratory analysis samples for science and society. The requirements for this goal are twofold; firstly requiring creation and consensus of data standards appropriate to describe many geochemical data types and acquisition methods, and secondly the promotion and adoption of standards within global data systems and geochemical communities. Such data standards are urgently needed to address the fragmented geochemical data landscape and directly improve the use of geochemical data for scientific discovery and transdisciplinary applications. Adoption of existing standards and development of new standards requires engagement and participation by the geochemical community to create appropriate resources and facilitate meaningful change in international data transparency and availability. OneGeochemistry is seeking new members from the geochemical community, from backgrounds of research and analysis and/or data management, to join the OneGeochemistry project and contribute their expertise and experience to help advance open scientific reporting standards. This splinter meeting hosted by OneGeochemistry will provide an outline of the project structure, opportunities, and how to get involved, and give a forum for the community to discuss pressing geochemical data issues and how these may be addressed.

Software is pervasive in modern research, enabling the generation, analysis and/or presentation of research outputs. Research software is a key driver of innovation and the economy. It focuses on software that is developed to serve a research purpose, rather than the standard software that some researchers also use for research purposes.

While software has started to be recognised internationally as a key part of facilitating trusted, reproducible research outputs and open science, recognition of research software as a valuable research input and output has lagged behind that of research data. AI-driven research is also dependent on software, although it is not always adequately understood that data preparation and model training are performed by software, and that models are implemented in software.

Significant effort is still needed to influence culture change towards research software across a broad spectrum of stakeholders, including researchers, institutions, funders, and publishers, and to develop and promote standards for developing research software that meets the needs of reliable, reproducible, and reusable research.

An upcoming event within the RS community will soon be organized to better engage change-makers, leaders and decision-makers from a range of stakeholder groups within the research software community, with equal representation of policy makers, national/international RSE associations, infrastructure providers, funders, university consortia, thematic communities (e.g. training), publishers, researchers on research software, etc.

In this meeting attendees will give their input on what are the topics and challenges that are important to be discussed in the future event.
