Abstract

This paper concerns the measurement of brightness temperature using the TRMM Microwave Imager (TMI) satellite microwave radiometer. Specifically, the development of an algorithm for correcting the effects of a slightly emissive reflector antenna on the measured earth scene radiance is presented. This algorithm is based upon rigorous radiative transfer theory and on-orbit reflector emissivity measurements during a deep space calibration, whereby the antenna viewed a homogeneous and isotropic cosmic background source of microwave radiance. These results will be used in the generation of the legacy brightness temperature product 1B11 V8 to be released during fall 2017.
