Abstract

Abstract Here we report a preliminary investigation of temperature retrieval utilizing the Air Force Defense Meteorological Satellite Program (DMSP) Passive Microwave Temperature Sounder (SSM/T) data under clear, cloudy and precipitating atmosphere conditions. Within the limited case studies and in the context of a statistical temperature retrieval program, we find that the recovered temperatures close to the surface suffer increased degradation as the observed rainfall rate increases when the temperature profiles are compared with radiosonde data. Differences between retrieved and observed temperatures near the surface are found to be as large as 15 K. Nonprecipitating clouds appear to have little effect on the temperature retrieval program from microwave observations.
