It provides information on atmospheric water in all of its forms (with the exception of small ice particles, which are transparent at microwave frequencies). AMSU-A provides information even in cloudy conditions.
What is AMSU-A?
AMSU-A is a multi-channel microwave radiometer which measure scene radiances in 15 discreet frequency channels (23-90GHz).
At each channel frequency, the antenna beamwidth is a constant 3.3 degrees (at the half power point). AMSU-A is part of the ATOVS package, together with MHS and HIRS. AMSU-A scanning is synchronized with MHS and IASI scanning.

GOME-2 is used to get a detailed picture of the total atmospheric content and vertical profile of ozone.
Microwave Humidity Sounder (MHS)
The MHS is designed to collect information on various aspects of the Earth's atmosphere and surface.
