The Polarimetric Scanning Radiometer (PSR) is an airborne passive microwave imaging radiometer developed by Georgia Tech and NOAA. It obtains polarimetric microwave emission imagery of Earth to characterize ocean and land surface features, precipitation, ice, and clouds. PSR operates across four microwave channels: 10.7 GHz, 18.7 GHz, 37 GHz, and 89 GHz. The PSR/A version of the sensor has an additional dual-polarimetric channel at 21.5 GHz. At an altitude of 22,000 feet above sea level, PSR has a spatial resolution of 0.3-2.2 km, depending on the frequency band and scan mode.
