Book Description
This report documents research that has been carried out for the purpose of furthering the understanding of infrared emissions in the non-LTE regions of the Earth's atmosphere. Our effort has consisted of developing and exercising computer models of the quiescent and aurorally disturbed atmosphere, analyzing data from rocket and satellite experiments to validate and extend the models, and drawing upon our experience to help plan for the MSX mission. Specifically, we have used our models to simulate data from the SISSI and MAP/WINE campaigns and the CIRRIS mission, perform benchmark calculations to validate radiative transfer algorithms, and study the effects of gravity waves on non-LTE populations and atmospheric cooling in the mesopause region. We have performed spectral analysis on CIRRIS data, and used the models to identify processes contributing to the 4.3 um emissions seen in the data. We present a detailed description of how to use Atmospheric Radiance Code (ARC), the non-LTE code that we employ for these purposes. We also summarize our role in MSX experiment planning, and software development for automated analysis of MSX Spectrographic Imager data.
