Aurorally enhanced infrared emissions
Abstract
Significant IR emission enhancements in the 2.9 micron region are examined that were measured from aboard an aircraft with an optically filtered radiometer which viewed the zenith through a liquid nitrogen cooled chopper collimator system. All-sky camera photographs verified that the enhancements were directly related to auroral events and that they occur for a wide variety of auroral formations including broad arcs, narrow arcs, coronas, patches, and breakups. The sources of these emissions is postulated to come from overtone chemiluminescent emission from chemically produced NO.
