Investigating the impact of geomagnetic storm over the ionosphere-thermosphere system of subauroral/midlatitude region using ISR observations and GOCE measurements.

We have investigated and validated thermospheric wind observations during geomagnetic disturbances using data from both ground-based and space-based instruments. Specifically, the thermospheric wind observations from mid-latitude ground-based Fabry-Perot Interferometers (FPIs) were compared with data measurements from the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite to examine and cross-compare results. We studied how thermospheric wind reacted to geomagnetic storms, particularly during the rising-maximum phases of the solar cycle 24. Understanding the behavior of wind parameters is critical to improving the understanding of the complex dynamics that occurs in the ionosphere-thermosphere system during storms in relation to geospace forecasts.
