Novel image measurements of OH mesospheric emissions and Leonid meteors were made using a sensitive Indium-Gallium-Arsenide (InGaAs) intensified camera during two NASA airborne campaigns; the Leonid MAC mission (November 2002), and the SOLVE II campaign (January 2003), using the NASA DC-8 Airborne Laboratory. For the Leonid mission three types of intensified cameras were operated, tow narrow band imagers to investigate the ablation signatures of meteors, and an InGaAs imager to study gravity wave variability over a large range of longitudes (two trans-Atlantic flights). The SOLVE II airborne mission was based in Kiruna, Sweden, and several extended nighttime flights were made into the high arctic region to measure ozone concentrations in conjunction with the SAGE III satellite instrument. As part of this mission we were given the opportunity to extend our InGaAs measurement of mesospheric airglow wave structure and IR emissions to polar latitudes. This mission also coincided with the NASA MaCWave rocket campaign that was conducted from Esrange, Sweden during this period. In this poster we present initial data and results primarily of the InGaAs measurements, obtained during these two missions.
