SA52A:
Advances in Equatorial Thermosphere and Ionosphere Studies I


Submit an Abstract to this Session


Session ID#: 61466

Session Description:
This session focuses on understanding the dynamic and coupling processes of the thermosphere and ionosphere at equatorial latitudes both during quiet and storm times, and addresses the current progress and understanding, as well as future challenges. This includes equatorial ionospheric response to geomagnetic storms, storm-time penetration and disturbance dynamo electric fields, equatorial spread F/plasma bubbles, scintillation and its effects on communication and navigation systems, equatorial electrojet, vertical coupling of the atmosphere and ionosphere, forcing from below (planetary waves, tides, gravity waves, etc.) and induced ionospheric disturbances such as TIDs, and longitudinal variations of thermospheric and ionospheric parameters. We welcome observational, theoretical, and modeling studies that advance our understanding and enable us to better forecast the low-latitude thermospheric and ionospheric behaviors, especially during geomagnetic storms. Presentations on new instrument and observational methods are also encouraged.
