Reduction, analysis, and interpretation of infrared sky background data taken from ICECAP rockets and aircraft, planning and coordination of experiments, characterization of auroral conditions, and other program support functions are reported. A digital computer program for compiling synthetic spectra of atmospheric emissions and absorption in the region just above 2.7 micrometers was developed, and applied to analyzing aurora - associated increases in radiance measured from jet transport altitude as vibrational excitation of NO molecules. The profile of approx. 5.4 micrometers radiation in the quiet E- and F-region is interpreted in terms of previously proposed mechanisms for exciting ambient NO. ICECAP 75 aircraft measurements of SWIR aurora and airglow are described, and support data on the flight missions are tabulated. A coordinated experiment on high-latitude hydroxyl airglow processes is detailed, and plans for supporting rocket experiments with the DNA617 radar and spectroradiometers that measure upper atmosphere temperatures are developed.
