Building Heliophysics Community Portal for Great Storms

Space weather is a multi-disciplinary research area connecting scientists from across all Heliophysics domains requiring the whole global community to work together. The COSPAR International Space Weather Action Teams (ISWAT, https://iswat-cospar.org) is a global hub for open collaborations addressing challenges across the field of space weather. Groups or individuals working on a specific topic can register a new action team and open it for others to join. Action Teams are organised into ISWAT Clusters by Heliophysics domains: Sun, Heliosphere, and Coupled Geospace system. ISWAT is an effort multiplier maximising return on investments by national/regional programs. A new Sun2Geospace  (S2G) Cluster  is a home to action teams focused on flows of space weather processes from origins at the Sun to impacts on Geospace and connecting the various aspects of global space weather phenomena, such as Solar/Geospace storms.

In support of the multi-team-cross-domain-interdisciplinary S2G Cluster and the entire Heliophysics community the Community Coordinated Modeling Center (CCMC, https://ccmc.gsfc.nasa.gov) is building an online Portal to facilitate community-wide comparative studies of Great Solar/Geospace Storms. The Portal aims to serve as a hub for all information connecting the various aspects of the Great Storms from solar surface to impact at Earth. The Portal includes a living database continuously populated by the community. The database incorporates interactive listings of publications, presentations, links to simulation outputs and observation data. In support of the project the CCMC generated run series tailored for storm studies and collected simulation outputs, observational data and interpretations (heliostories) from a broad range of sources. CCMC tools for space weather analysis (including Integrated Space Weather Analysis – ISWA system and Database of Notifications, Knowledge Information – DONKI) have been upgraded to enable tailored layouts and listings for specific time periods. The presentation will highlight recent advances and present examples of comparative analysis focusing on Great Storms that occurred over the Heliophysics Big Year (October 2023-December 2024).
