Fig. 1From: Longitudinal structures of zonal wind in the thermosphere by the ICON/MIGHTI and the main wave sourcesThe altitude–longitude distribution of zonal wind during daytime in the altitude range of 100–300 km at three latitudes, \(15^\circ \, \text {N}\), \(25^\circ \, \text {N}\), and \(35^\circ \, \text {N}\). The local time is between 10:00 h and 14:00 h. Each subplot is divided into two panels, the top panel shows zonal wind from the 630.0 nm red line emission of atomic oxygen in the altitude range of 180–300 km, and the bottom panel shows zonal wind from the 557.7 nm green line emission of atomic oxygen in the altitude range of 100–210 km. a–r Represent the longitudinal structure of zonal wind in February, April, June, August, October and December at \(15^\circ \, \text {N}\), \(25^\circ \, \text {N}\) and \(35^\circ \, \text {N}\), respectivelyBack to article page
