2023-04-04 Longitudinal Structures of Zonal Wind in the Thermosphere by the ICON/MIGHTI and the Main Wave Sources doi:10.57760/sciencedb.space.00617 en In this study, the neutral wind observations from the Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) instrument onboard Ionospheric CONnections (ICON) are used to investigate the longitudinal structure of zonal wind between 100 and 300 km during daytime. The longitudinal wavenumber 1-4 patterns (WN1-WN4) are extracted, and the altitude-month distributions of WN1-WN4 and their contributions to the longitudinal structure are compared. And the main wave sources of WN1-WN4 are further investigated in the 100-106 km and 210-300 km altitude regions.
