A scientific flight over Fort Collins CO (40.6¿N, 105¿W) was conducted on the night of April 15--16, 1990, during the ALOHA-90 campaign. In this Colorado mission, a direct comparison between measured mesospheric O2 and OH rotational temperatures with the airglow instruments on board the Electra and simulataneously measured Na temperatures by a ground-based narrowband Na lidar has been made. This first comparison resulted in general agreement in measured temperatures between different instruments. ¿American Geophysical Union 1991
