Abstract : This report focuses on two major subject areas. The first of these includes the analysis and interpretation of spectral earthlimb emission data obtained in the DNA sponsored SPIRE experiment, and the implications of this analysis for application to cases of interest to the AFGL/DNA community. These would include quantitative specification of ambient non-LTE mechanisms for high altitude infrared radiance, which would also become important infrared background effects in the nuclear case, as well as quantitative i dentification of deficiencies in the current AFGL High Altitude Infrared Radiance Model. The second subject area involves a supporting laboratory experiment to obtain data pertinent to understanding the nuclear effects of fluorescence of fireball light. The laboratory experiment also directly supports the analysis and interpretation of the SPIRE data and the interpretation and analysis of high resolution spectral earthlimb emission data that are expected to be obtained in forthcoming DNA sponsored high resolution spectral earthlimb emission experiments. Analysis and interpretation of spectral earthlimb emission data obtained in the SPIRE experiment was aimed at quantifying the role of CO 2 in the formation of the non-LTE earthlimb at wavelengths 15, 4.3 and 2.7 microns. Non-LTE mechanisms for CO 2 emission in these wavelength regions were verified and in some cases upgraded by comparison between predictions and the SPIRE data.
