Abstract
Thermospheric temperature, composition, and winds at F region heights over the southern hemisphere polar cap have been measured by the Dynamics Explorer 2 (DE 2) satellite during October-November 1981. Perigee of the DE 2 satellite during this period was over the southern hemisphere polar cap, and measurements made along 0900-2100 local time polar passes are used to determine the average universal time dependence of thermospheric properties for this local time slice. The F region wind vector is derived from the meridional wind component measured by the Fabry-Perot interferometer (FPI) and the zonal wind component measured by the wind and temperature spectrometer (WATS) instruments on board DE 2. The neutral gas temperature is derived from FPI and WATS measurements, and the compositional structure is determined from the neutral atmosphere composition spectrometer instrument.
