Two spectroscopic instruments, a {1/4} meter Ebert-Fastie spectrometer and a Michelson interferometer, were flown aboard the NCAR Electra during the ALOHA-90 campaign. These instruments were designed to carry out measurements of the brightnesses and rotational temperatures of the O{sub 2} Atmospheric (0-1) band and several OH Meinel bands simultaneously with sodium lidar observations. The spectrometer results taken during the nights of March 25 and March 31 are reported. Wave-like oscillations in both O{sub 2} and OH airglow brightnesses were clearly present during both flights and a strong positive correlation of OH band brightness with sodium column density was found. A slightly weaker correlation of O{sub 2} band brightness with sodium column density was also detected. The measured brightness ratio between the OH (7-4) and (7-3) bands is found to be 11.2{plus minus}0.3, which is in good agreement with the calculated ratios of 12.9 by Mies (1974) and 10.2 by Langhoff et al. (1986).
