G2B Ionosphere variability:
Summary of Key Recommendations
Ionospheric modeling has seen enormous progress.
The contribution of data assimilation and ML in ionospheric specification still needs to be better understood/evaluated also in coupling with physics-based approaches.
Advances in modeling capabilities
Ionospheric multi-day forecasts remain an open challenge, mainly related to the forecast of the models’ drivers.
To move beyond present forecast range (~12 hrs), the community needs reliable solar/solar wind predictions.
Due to the plethora of available models and the advanced needs, the systematic assessment of the ionospheric models’ performance is considered a high priority task.
In recognition of the open access policy benefits, it is increasingly supported by model developers and funding agencies. This support should be continued.
Maintenance and expansion of observational networks should be continued.
Need for space-based experiments (e.g., radio occultation, beacon transmitters) in middle and high/polar latitudes.
Exploitation of relevant experiments should be further explored (e.g., radio amateur data, LOFAR).
Partnership between scientific and commercial sectors in data sharing is still an open issue.
Scaling of the ionospheric activity level for operational applications is a strong requirement.
Advances in observational, monitoring and detection capabilities
Optimization of observational resources
Activities relevant to data quality control and validation need to be intensified/ coordinated.
Activities for harmonized/standardized access to near-Earth space data should be continued/intensified.
Take advantage of new/upgraded model simulations results.
Take advantage of new/upgraded observational capabilities.

G2B-05: Ionospheric models validation
Lead: Ioanna Tsagouri
Tuesday, AM1; Room: Trinidad
Wednesday, AM1; Room: Antigua
According to G2B recommendations included in the COSPAR Space Weather Roadmap (2022 - 2024), the assessment of ionospheric models' performance is considered a high-priority task for the ionospheric community. Addressing the needs includes: the establishment of wide/unified validation efforts, based on agreed metrics and standardized procedures; archived model and validation results to help more sophisticated data-model comparisons and keeping track of the progress; carefully designed validation tests, able to accommodate also operational models/needs. This session is organized in response to the aforementioned recommendations to discuss key requirements and new opportunities for the development of a validation framework that meets the community's needs, including the development of model assessment tools on CAMEL at CCMC.
G2B-05 Establishment of standardized model validation campaigns (3-D electron density distribution).
Including existing and new observational opportunities
Challenges in assessing modeling capabilities to capture the space weather impact
Monitoring, studying and modelling the polar atmosphere is very challenging!
It is possible only through collaborative efforts.
The G2B-12 Team wants to bring into the ISWAT community the AGATA Scientific Research Programme endorsed by SCAR.

G2B-12 Team: Antarctic Geospace and ATmosphere reseArch (AGATA) (New G2B Action Team)
AGATA aims to significantly advance the current knowledge of the polar atmosphere and geospace, also in the global and interhemispheric context.
RATIONALE
AGATA gathers communities that investigate the polar weather, atmosphere, and geospace to study the coupling between different atmospheric layers and the impact of solar-terrestrial interactions for the conditions in the atmosphere (both lower and upper atmosphere).
This opens for innovating science encompassing different atmospheric layers and near-Earth space.
AGATA:
AGATA offers a common research and collaborative
platform always open to new members
Timeframe: 8 years till next IPY (2032-2033)
Officiall kick-off meeting: March 26-28 (online)
