HIRS is a scanning radiometer. It scans the Earth in 56 Earth views per scan line. At each view, it stops to rapidly scan 20 channels by rotating a filter wheel, through which the radiation falls on any of three detectors. The channel suite consists of twelve longwave channels using a HgCdTe detector (6.52—14.95 μm), seven shortwave channels with a InSb detector (3.76—4.57 μm), and one visible channel. An overview of the channels is given later.

HIRS pre-Beta is aveilable via CEDA more details to follow.
