G10: Ionosphere and Plasmasphere Density Profiles

Friday, August 22  08:00-09:20,  Room #14

This session will emphasize the importance of ionosphere and plasmasphere electron density profiles in characterizing the upper atmosphere from the bottomside through to the topside and plasmasphere. Measurements of ionospheric characteristics like hmF2 and NmF2 provide essential inputs for any model, but they are not sufficient to describe the global density distribution in the ionosphere up to the plasmasphere. Total Electron Content measurements from GNSS (Global Navigation Satellite System) satellites on the other hand only provide integral information up to the satellite altitude. This session will review the current state of profile modeling covering both the ionosphere and plasmasphere. Presentations are solicited that discuss current modeling approaches and their global reliability, as well as future mission and measurement plans. The session will consist of invited, contributed, and poster presentations.
