The NASA Global Hydrology Resource Center (GHRC) DAAC published the Conical Scanning Millimeter-wave Imaging Radiometer (CoSMIR) instrument micro article. The CoSMIR instrument is an airborne, 9-channel radiometer originally developed to calibrate and validate the Special Sensor Microwave Imager/Sounder (SSMIS) for the Defense Meteorological Satellite Project. It has been modified to serve as a high-frequency simulator for the Global Precipitation Measurement Microwave Imager (GMI). CoSMIR measures microwave brightness temperatures enabling its use in satellite validation, precipitation, convection, and cloud studies, as well as tropical cyclone research. This micro article provides an overview of CoSMIR and its applications to support current and future GHRC publications.
