Compact Scanning Millimeter-wave Imaging Radiometer (CoSMIR)

Instrument Type
ICE-POP 2018
Global Precipitation Measurement (GPM) Mission

CoSMIR is nine channel total power radiometer, spanning 50 GHz to 183 GHz, originally designed for calibration and validation of the Special Sensor Microwave Imager/Sounder. Since its construction, it has been modified to conform to the GPM Microwave Imager (GMI) high frequency channels. CoSMIR has flown on NASA’s ER-2 and DC-8 aircraft. The two-axis gimbaled scan mechanism allows for a variety of scan strategies, including conical and across-track scans.
