Calibration and validation activities of the Airborne Polarimetric Microwave Imaging Radiometer - APMIR

The Airborne Polarimetric Microwave Imaging Radiometer (APMIR) was designed and built by the Naval Research Laboratory as a tool for calibration and validation (cal/val) of the Coriolis WindSat and Defense Meteorological Satellite Program SSMIS satellite radiometer sensors. During March and April of 2004, APMIR underflew both WindSat and SSMIS a number of times as part of the respective cal/val campaigns. A subset of the results is presented here.
