Daytime thermospheric temperatures, wind velocities and emission intensities derived from ground based observations of the OIλ630 nm airglow line profile

Dual Fabry-Perot spectrometer measurements of daytime thermospheric temperature and wind velocity: data analysis procedures

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.
