Thermospheric Winds and Temperatures Observed by OI 6300 Angstrom Emission at Sao Jose dos Campos, Brazil, during the Second Sundial Campaign

摘要

Thermospheric neutral wind and temperature observations measuring OI 6300 angstroms Doppler shift and broadening by means of a Fabry-Perot interferometer were carried out at Sao Jose dos Campos (23.2 deg S, 45.9 deg W), Brazil, during the period September 30 to October 6, 1986. This period of observations included the second SUNDIAL campaign. Here, results are presented and compared with the Thermospheric Global Circulation Model (TGCM) predictions for equinox conditions during solar minimum for this station.
