HIRS/1, flown on NIMBUS-6, was an improved version of the 7
channel ITPR (Infrared Temperature Profile Radiometer) on NIMBUS-
5. HIRS/2, an adaptation in turn of HIRS/1, measures radiation
in 20 channels - one visible and nineteen infrared, from short
wavelength (4.3 micron) to long (15 micron). The instrument is
intended to obtain vertical temperature profiles, surface
temperature, water vapor profiles and cloud coverage. HIRS/2 is
part of the TOVS package (see the sensor reference for TIROS OPER
