AMSU-B is a cross-track passive microwave humidity sounder using water-vapour absorption bands.
AMSU-B (Advanced Microwave Sounding Unit-B) is a cross-track passive microwave radiometer designed for atmospheric humidity profiling using water-vapour absorption bands. It operates five channels at 89 GHz, 150 GHz, 183.31+/-1 GHz, 183.31+/-3 GHz, and 183.31+/-7 GHz.[1] The instrument scans cross-track, providing measurements sensitive to tropospheric water vapour at multiple altitudes.[2]
AMSU-B was built by Northrop Grumman and flew on NOAA-15 (from August 1998), NOAA-16, and NOAA-17.[1] It operated in conjunction with AMSU-A, which provided the paired temperature-profiling channels on those platforms. From NOAA-18 onward and on all three MetOp satellites, AMSU-B was succeeded by the Microwave Humidity Sounder (MHS).[1]
