HY-2B Calibration Microwave Radiometer
Calibration microwave radiometer flown on HY-2B.
HY-2B Calibration Microwave Radiometer (CMR) is a passive microwave radiometer flown with the HY-2B ocean altimetry mission for radar-altimeter water-vapour correction.[1][2] CMR uses three frequencies: 18.7, 23.8, and 37 GHz.[2][3] Within its retrieval role, 23.8 GHz supports atmospheric water-vapour retrieval, 37 GHz supports cloud liquid water retrieval, and 18.7 GHz captures sea-surface wind and roughness contributions.[3] The instrument is capable of passive microwave radiometry for altimeter path-delay correction.[2] HY-2B also carries a separate five-frequency Scanning Microwave Radiometer; CMR is the three-frequency altimeter-correction instrument, not that SMR payload.[1][2]
