It is very similar in design to the AMSU-B instrument, but some channel frequencies have been altered.
It is used to study profiles of atmospheric water vapor and provide improved input data to the cloud-clearing algorithms in the IR and MW sounder suites.
The follow on instrument to MHS is MWS on the Metop-SGA satellites.
[1] The Microwave Humidity Sounder was designed and developed by Astrium EU in Portsmouth, UK, under contract to EUMETSAT.
