OI 630.0 nm Optical Measurements of Neutral Winds, Temperatures and Airglow Enhancements during the BIME Program.

Abstract : A 100 mm aperture, field-widened Fabry-Perot interferometer was used in support of the B.I.M.E. F-region chemical release program to measure 630.0 nm night-glow line profiles and from this to determine the pattern of F-region thermospheric dynamics (neutral velocity vector vn and neutral temperature Tn versus time) from 24 Auguest 1982 to 19 September 1982 at Natal Brazil. A 3-channel, sky-mapping filter photometer measured the temporal and spatial evolution of the 630.0 nm airglow enhancement produced by the first B.I.M.E. release (8 Sept. 1982). Clouds over our observing site obscured the second B.I.M.E. release (13 Sept. 1982). (Author)
