GCPEX CoSMIR Dataset Published

GHRC has published the GPM Ground Validation Compact Scanning Millimeter-wave Imaging Radiometer (CoSMIR) GCPEx dataset. The CoSMIR plays the role as an airborne high-frequency simulator for the GPM Microwave Imager (GMI), which will launch in 2014.  The CoSMIR was modified with a new scan mode to acquire both conical and cross-track scan data simultaneously in a given flight satisfying the requirements of the Precipitation Measurement Mission (PMM) algorithm development team.  This CoSMIR dataset provides well-calibrated radiometric data from 9 channels between 50-183GHz with the  accuracy on the order of +-1K.  All channels besides the 89 and 165.5 GHz are horizontally polarized.
