Interim report on the determination of atmospheric temperature profiles from satellite radiance measurements

摘要

A Maximum A Posteriori (MAP) estimator is used for the purpose of retrieving atmospheric temperature profiles from Selective Chopper Radiometer (SCR) satellite measurements of emission from the 15µm carbon dioxide absorption band of the Earth's atmosphere. Diagnostic methods are derived so that confidence regions, vertical resolution and information content of all observations may be determined. The theoretical aspects of the retrieval problem are illustrated by application to a realistic temperature profile.
