Fabry-Perot Interferometer and Skymapping Photometer Determinations of Midlatitude F-Region Neutral Winds and Temperatures and Airglow Enhancement/Depletions.

A 100 mm aperture, field-widened Fabry-Perot interferometer and a sky-mapping filter photometer were used in support of the IMS F-region chemical release program at Wallops Island, VA. On the night of the successful SF6 release near local midnight (8/9 November 1983) the neutral wind components vz (meridional) and va (zonal), as well as the neutral temperature Tn of the thermosphere were determined from 02 h UT to 06 h UT. Divergence in the zonal flow was noted. No 630.0 nm airflow enhancement/depletion was detected.
