Variations in the thermospheirc compositions
Abstract
Satellite based far-ultraviolet (FUV) observations provide an important and unique way to determine the thermospheric compositions, such as O/N2 column density ratio and NO column density. We will use the data from TIMED/GUVI, DMSP/SSUSI and IMAGE/FUV and other measurements to discuss the composition variations caused by different drivers (solar EUV, magnetospheric energy input, wind and ion-neutral coupling). Applications of the thermospheric composition measurements for satellite drag estimation and ionospheric nowcast and forecast will be briefly discussed.
