Dynamics of the Thermosphere and Ionosphere System at Low and Middle Latitudes due to the External and Internal Forcing

Session ID#: 162875

Session Description:
The GOLD, COSMIC-2 and ICON missions, along with existing ground-based and space-based observations as well as advances in numerical modeling capabilities, provide an exciting opportunity to study the variability in the thermosphere and ionosphere system due to various forcing from above and below. Topics of interest include, but are not limited to, the changes of the winds, composition, and thermal structure in the thermosphere, as well as electric field and electron density in the ionosphere due to geomagnetic activity, waves arising from the lower atmosphere and sudden stratospheric warmings, etc. We solicit presentations that address scientific issues with respect to variability in the thermosphere and ionosphere using observations, numerical simulations, and general circulation models.
