Abstract

During the 19701s, Air Force Geophysics Laboratory field measurement programs identified several aurorally enhanced infrared emitters in the upper atmosphere including chemiluminescentinescent NO emission at 2.8 μm and vibraluminescent CO2 emission at 4.3 μm. Models generally predict a much. smoother background at 4.3 μm due to CO2 radiation trapping. To test these models, AFGL is developing an earth limb sensing experiment (ELIAS) to measure auroral structure simultaneously in three colors: 3914A, 2.8 μm and 4.3 μm. The cryogenic sensor employs three scanning five detector arrays, telescoped to intercept an 8 by 8 km scene at the earth limb with spatial and temporal resolutions of 1.5 km and 0.1 sec, respectively. A near term auroral rocket probe experiment is planned for October 1981 followed by two space shuttle flights in the mid 1980's. The current knowledge of auroral earth limb backgrounds, details of the ELIAS sensor, and the proposed measurement technique are presented.
