[PEM13-16] Delineating the tidal influence on the F-region using ICON during 2021
Keywords:atmospheric tides, F-region ionosphere, model and observation
The Ionospheric Connection explorer (ICON) is designed to study the coupling between the lower atmosphere and space by observing among others low latitude neutral winds, temperature, ion drift and plasma characteristics. The numerical model TIEGCM supports the interpretation of the observations. In this study we want to isolate and quantify the tidal influence on the ion drift and plasma distribution in the F-region by conducting numerical experiments with and without tidal forcing. We will focus on some prevalent tides to characterize their change with the background atmosphere and tidal interactions especially during periods of moderate geomagnetic activity. We will set the simulation result in perspective to the ICON observations to evaluate the tidal influence on the F-region.
