2015 Workshop: Ionosphere and thermosphere variation
Larry J. Paxton
Significant disturbances in the ionosphere and thermosphere occur during geomagnetic storms due to intense energy input from the magnetosphere and solar wind. However, for a given solar wind and IMF condition, the response of the thermosphere (temperature, density, composition) and ionosphere (density, temperature, ion species) could be different, depending on preconditioning, solar cycle, season, hemisphere, tidal forcing, etc. We welcome all short presentations that briefly review: our current knowledge; new findings; and future plans (data analysis, modeling and measurement) to further advance our understanding of the globally coupled T-I system. The recent March 17, 2015 intense storm provides a good opportunity to test our understanding of the T-I system.

The proposed session aims to review recent progress and unsolved science questions (e.g. preconditioning) in the global I-T variations and coupling. It also provides a forum for the community (measurement and modeling)to work together on some events. It directly aligned with the CEDAR Strategic Thrusts #1 and #2.
