Advances in Understanding Dynamics and Energetics of the Thermosphere-Ionosphere System at Low and Middle Latitudes
Session ID#: 250986
Session Description:
The thermosphere-ionosphere (T-I) system is a nexus where dynamics and energetics are regulated by momentum and energy input from solar insolation, magnetospheric forcing, and atmospheric waves propagating from the lower and middle atmosphere. The past several years have offered far-reaching advances in understanding this highly dynamic and coupled system, thanks to recent satellite missions, existing ground-based observations, and advancements in numerical modeling capabilities. This session promotes a broad range of research topics, including, but not limited to, responses of thermospheric composition, thermal structure, neutral winds and ionospheric electric field and electron density to external forcing from solar and geomagnetic activity, and internal forcing due to atmospheric waves, polar vortex activity, etc. We solicit research papers that leverage observations and simulations to explore complex variability in the T-I system across various spatial and temporal scales.
