Abstract | |||||||||||
| This report describes the development of atmospheric infrared (IR) radiance models to describe atmospheric NLTE radiation and structure in the IR spectral region for arbitrary diurnal conditions, Several of the models have been included into the suite of standard Air Force atmospheric radiation computer models. These models calculate the radiation from quiescent, auroral, and structured atmospheres in the 2-40 microns spectral region for arbitrary paths above 30 km under nighttime, terminator, and daytime conditions. In addition, a radiance model based on SHARC and MODTRAN has been developed which allows arbitrary viewing geometries from the ground to 300 km. In conjunction with the research into atmospheric radiance models, an atmospheric generator which uses empirical models to generate atmospheric profiles for the solar terminator and other systematic atmospheric variations has been developed. If further support of the atmospheric radiance model program, a detailed chemical kinetic model has been developed to describe O3 emission in the mesophere resulting from high-lying vibrational states. The predicted O3 spectral radiances are in good agreement with the SPIRIT-1 and CIRRIS-1A data sets. | |||||||||||
