Advanced Spectral Modeling Development

This report describes the results of a basic research program to develop advanced spectral modeling techniques to treat a variety of current topics in spectroscopy and radiative transfer relevant to the modeling of atmospheric transmission and radiance fields. These include optimizing multiple scattering, surface properties, line coupling, line shapes, interferometric instrument function, and model validation. The overall goal of this research was the improvement of transmittance/radiance simulation modeling physics through continual model validation of results. Results of this study will enhance the capability to model atmospheric transmission and emission. The report is divided into two sections based on model physics areas which were investigated in the course of the contract.
