Raw microwave brightness for weather (METOP-B)
What it measures. Records how much microwave energy the surface and atmosphere give off at five frequencies, expressed as how 'warm' things look to the sensor. It's a basic, calibrated measurement rather than a finished weather product.
How it's made. Comes from the MHS microwave instrument on the METOP-B satellite, recalibrated to a common standard so it lines up with similar sensors on other satellites.
How & where you'd use it. A building-block input that feeds higher-level rain and humidity products; most people use it indirectly rather than on its own.

Official description
Version 07 is the current version of the data set. Older versions will no longer be available and have been superseded by Version 07. All 1C products have a common L1C data structure, simple and generic. Each L1C swath includes scan time, latitude and longitude, scan status, quality, incidence angle, Sun glint angle, and the intercalibrated brightness temperature (Tc). One or more swaths are included in a product. The radiometer data are recalibrated to a common basis so that precipitation products derived from them are consistent. 1CMHS contains common calibrated brightness temperature from the MHS passive microwave instrument flown on the NOAA and METOPS satellites. Swath S1 is the only swath and has 5 channels (89.0GHzV, 157.0GHzV, 183.3GHz+/-250MHzH, 183.3GHz+/- 500MHzH, and 190.3 GHzV). MHS is very similar to AMSU-B. The scan period is 2.667s.
