Description
Summary:Daytime thermospheric temperatures and wind velocities have been inferred from dual Fabry-Perot spectrometer observations of the atomic oxygen emission line at lambda630 nm, and this paper details the analysis procedures applied to the recorded spectra. Numerical simulation of the recorded spectra was used to examine the limitations imposed by analysis assumptions and by the influence of atmospheric molecular oxygen and water vapor absorption lines near lambda630 nm. The observational and analysis procedures provide a reliable ground-based means of monitoring the thermal and dynamical state of the neutral thermosphere during the daytime.
