MHS is a cross-track passive microwave humidity sounder flown on operational meteorological satellites.

Sensor

MHS (Microwave Humidity Sounder) is a cross-track passive microwave radiometer designed for atmospheric humidity profiling. It operates five channels at 89 GHz, 157 GHz, 183.311+/-1 GHz, 183.311+/-3 GHz, and 190.311 GHz.[1] The second channel at 157 GHz is a window channel distinct from the 150 GHz channel carried by its predecessor AMSU-B.[1] MHS provides tropospheric water-vapour profiles and is used operationally in numerical weather prediction.[2]

MHS was built by Astrium Ltd under contract to EUMETSAT.[3] It succeeded AMSU-B starting with NOAA-18, and flew on NOAA-18, NOAA-19, MetOp-A, MetOp-B, and MetOp-C.[1][4] On MetOp platforms it operates alongside AMSU-A, providing complementary humidity profiling to AMSU-A temperature soundings.[3]
