What is AMSU-A?

AMSU-A is a multi-channel microwave radiometer which measure scene radiances in 15 discreet frequency channels (23-90 GHz).

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.
