Five-frequency passive microwave radiometer imager flown on HY-2B for sea-surface temperature, wind and water-vapour observations.
HY-2B Microwave Radiometer Imager is a conical-scanning passive microwave radiometer for all-weather sea-surface temperature, wind, and total-column water vapour observation. It carries five frequencies and nine channels at 6.6, 10.7, 18.7, 23.8, and 37.0 GHz, with horizontal and vertical polarization except that 23.8 GHz is a V-polarized channel [1]. The scan geometry is conical at a 55 degree zenith angle with a 1600 km swath and daily global coverage [1]. The 1.2 m antenna drives band-dependent footprints from 80 x 120 km at 6.6 GHz to 15 x 22 km at 37 GHz [1]. The instrument performs passive microwave radiometry on HY-2B. Its utilization period runs from January 2019 to 2026 [1].
