This post-Roadmap meeting aimed to review the G2B cluster activities in order to energize activities of the teams and discuss the potential establishment of new teams with new actions and collaborations following the updated recommendations.
Key discussion points/results
- Short review of G2B contribution to roadmap: ionosphere variability recommendations
- The G2B models’ validation teams plan to continue with post-event validation studies and probably, the development of an ionospheric scoreboard following the updated roadmap recommendations. Collaboration links with the relative Geospace scoreboard initiative have been established.
- TEC forecasting using ML techniques is growing interest but at the same time it is necessary to have scoreboards to make it benchmark. Ionospheric scintillation prediction requires coupled models from different remote sensing observations. Coupling data assimilation with ML could help in high-lead time in forecasting. G2B-10 team wants to collaborate and be in pace with ISWAR roadmap activities.
- Suggestions for potential improvements in the G2B Cluster network/work plan:
- D-layer plays an important role in controlling the HF absorption. The D-layer is strongly disturbed during solar flares and also strongly forced by particle precipitation from the radiation belts. Being too high for balloons and too low for spacecraft, the powerful to study and survey its time evolution is to use VLF measurements. Such measurements enable continuous survey in particular above oceans, where ground-based instruments cannot be located. Several network of VLF receivers exist, around the polar region the south and latin America and also north America and a new one in development around equatorial regions.
- Encourage observing system experiments (OSSEs/OSEs) that are of growing interest for space weather community.
