摘要：

Physical algorithms for retrieving temperature profiles explicitly employ the physics of radiative transfer. Consequently, it is necessary to do the forward problem accurately before attempting the retrieval problem. This paper discusses the various problems that arise, and their solutions, in doing forward calculations over oceans. These problems include that of determining: When the measurements are cloud contaminated, the amount of liquid water in the fields of view, the surface emissivity under both clear and cloudy conditions, corrections for liquid water contamination of the measurements, adjustments for deficiencies in the radiative transfer model, and compensation for measurement discrepancies by using shrinkage estimation. These procedures are developed for SSM/T data and their validity is checked by comparing the forward calculations with the corresponding satellite measurements. Application of the procedures to an independent data set confirms their veracity.
