Abstract

The ELIAS (Earth Limb Infrared Atmospheric Structure) experiment was flown from the Poker Flat Research Range, Alaska in 1983 and successfully monitored visible and infrared emissions from an IBC III+ aurora. Measure- ments were performed in both staring and scanning modes over several hundred seconds. The data for short- and mid-wave infrared regions have been analyzed in terms of auroral excitation of NO, CO2 and NO+ vibrational bands, and auroral excitation efficiencies and kinetic implications will be presented.
