Software is critical to the success of science. Creating and using Free and Open Source Software (FOSS) fosters contributions from the scientific community, creates a peer-reviewed and consensus-oriented environment, and promotes sustainability of science infrastructures.
Providing open access to source code also permits reuse of data, reproducibility of science, and creates scientific transparency. Open science is only possible when access to data is open, and data is analysed using open source software. This requires taking responsibility for software development, and adopting stewardship practices for managing, processing and disseminating scientific data products and related services.
This session will also discuss the publication and citation of scientific free and open source software as part of the general record of science and as part of the track record of the scientists who create or apply FOSS tools in their research.
This session will look at the role of FOSS in the geosciences with a special emphasis on the interoperability among established and developing FOSS-tools within geoinformatics. The session will be a forum for the latest advances in FOSS-empowered research, for successful applications of existing FOSS tools for geoscientific tasks, as well as for new developments in geoscience-related to FOSS.

This session aims to highlight Earth Science research concerned with state of the art computational and data infrastructures such as Clouds (commercial, on premis, European EOSC ) and HPC (Supercomputer, Clusters, accelerator-based systems (GPGPU, FPGA)).

We will focus on data intensive workflows (scientific workflows) between Infrastructures e.g. European data and compute infrastructures down to complex analysis workflows on an HPC system e.g. in situ coupling frameworks.

The session presents an opportunity for everyone to present and learn from results achieved, success stories and experience gathered during the process of study, adaptation and exploitation of these systems.

Further contributions are welcome that showcase middleware and tools developed to support Earth Science applications on Cloud and HPC, e.g. to increase effectiveness, robustness or ease of use.

Topics of interest include:
- Data intensive Earth Science applications and how they have been adapted to different HPC infrastructures
- Data mining software stacks in use for large environmental datasets
- HPC simulation and High Performance Data Analytics e.g. code coupling, in-situ workflows
- Experience with Earth Science applications in Cloud environments e.g. solutions on Amazon Web Services, Google Earth Engine, Microsoft Azure, and Earth Science simulation codes in private and European Cloud infrastructures (Open Science Cloud)
- Tools and services for Earth Science data management, workflow execution, web services and portals to ease access to compute resources.
- Tools and middleware for Earth Science applications on Grid, Cloud and on High Performance Computing infrastructures.
- Earth Science Application using cloud native solutions
- Innovative Evaluation and Prediction Applications for Large Earth Science Datasets

The term RSE, originally coined by the UK RSE association (https://rse.ac.uk), says the following about RSEs: "A growing number of people in academia combine expertise in programming with an intricate understanding of research. Although this combination of skills is extremely valuable, these people lack a formal place in the academic system." Surveys among RSEs in Australia, New Zealand, the UK, and Germany found that majority of the respondents prioritised: (1) Increasing recognition of the RSE role, (2) Building appropriate position descriptions and KPIs for better career opportunities, and (3) Developing a stronger community.

This session is calling for examples and success stories from geoscience community members who contribute to research software but face the above challenges.

We welcome contributions from RSEs across the EGU family. Topics surrounding career growth can include but are not limited to sharing experiences of:
- Creating and/or maintaining an RSE group
- Effective RSE focused events [e.g. career fairs, workshops..]
- Factors that influence RSE career progression
- Effective teaching strategies at all stages of RSE life
- Building sustainable development communities
- The recognition, or lack, of RSEs in academic outputs
- Skills required for RSEs [HPC, FPGAs, cloud, containers, ML, …]
- Thoughts on where "we" need to make improvements in RSE life

The session will start with a short report on a survey initiated after last year’s EGU on RSEs in the geosciences. Your participation in the survey is still welcome: https://bit.ly/rse-survey-egu

Citizen science (the involvement of the public in scientific processes) is gaining momentum in one discipline after another, thereby more and more data on biodiversity, earthquakes, weather, climate, health issues among others are being collected at different scales that can extend the frontiers of knowledge. Successful citizen observatories can potentially be scaled up in order to contribute to larger environmental and policy strategies and actions (such as the European Earth Observation monitoring systems) and to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate in environmental decision making, can raise awareness about environmental issues and can help bridge the science-society gap. Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review to transparently publish and share scientific research - thus leveraging Citizen Science and Reproducible Research.

Both, open science in general and citizen science in particular, pose great challenges for researchers, and to support the goals of the various openness initiatives, this session looks at what is possible nowadays and what is ready for application in geosciences. Success stories, failures, best practices and solutions will be presented, in addition to various related networks. We aim to show how researchers, citizens, funding agencies, governments and other stakeholders can benefit from citizen science and open science, acknowledging the drawbacks and highlighting the opportunities available for geoscientists.

In this session, we are looking for successful approaches of working with citizen science and open science to bridge the gap between a multitude of stakeholders in research, policy, economy, practice and society at large by finding emerging environmental issues and empowering citizens. This session shall be an open space to exchange experiences and to present either successful examples or failed efforts. Learning from others and understanding what to adopt and what to change help the participants in their own undertakings and new initiatives, so that they become future success stories.

We want to ask and find answers to the following questions:
Which approaches can be used in Earth, Planetary and Space Sciences?
What are the biggest challenges and how to overcome them?
What kind of citizen scientist involvement and open science strategies exist?
How to ensure transparency in project results and analyses?
How to evaluate successful bridging of the science-society-gap?
