Observed and Modeled Dynamics of the Thermosphere-Ionosphere System

Session ID#: 75513

Session Description:
Exciting new developments in the study of Earth’s thermosphere and ionosphere have been enabled by ground- and space-based observations (such as GOLD, ICON, COSMIC-2, TIMED, etc.) which are augmented by modeling experiments. These investigations include, but are not exclusive to, O and N2 and their relationship to the ionosphere, forcing of the thermosphere and ionosphere from above and below, the thermal structure of the thermosphere, the role of minor species in the thermosphere, disturbances by geomagnetic storms, and the influence of composition changes on the ionospheric F2 peak and the topside ionosphere.  Papers in this session will address issues related to the dynamics of the thermosphere and ionosphere using observations, data analysis and models.
