Atmospheric Tidal Study using ICON/MIGHTI Observations
Abstract
Atmospheric tides have important roles in driving atmospheric coupling process from the lower atmosphere to the mesosphere, thermosphere, and ionosphere. NASA's Ionospheric Connection Explorer (ICON) satellite was launched on 10 October 2019 and has been observing atmospheric temperatures and winds in the latitude range of 10S-40N. Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) is one of the instruments on ICON measuring temperature and winds. In this work, the first year of ICON/MIGHTI tidal observations will be presented for both migrating tides and non-migrating tides. In addition, results of Hough Mode Extension (HME) using ICON tides in the latitude range of 10S-40N will be presented here. Results are compared to SD-WACCM-X simulations and also SABER observations.
