Abstract:

This contract was for a basic research program to investigate the effects of clouds, precipitation and surface emissivity on microwave satellite sensors and their influence on atmospheric retrievals using the Unified Retrieval UR technique. The work consisted of the following tasks development of databases of brightness temperatures from various satellite sensors development databases of conventional analysis to verify the presence and amount of clouds and precipitation and for verification of retrieval results the application of the UR techniques to the satellite sensor data and the assessment of the accuracy of UR techniques in the presence of clouds. There was no measurable decrease in the UR performance in non-precipitating cloud cases. In cases with precipitating clouds, the UR performance was degraded as measured by the residual, which increased with increasing rain rate within the FOV.
