  skos:definition """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
      VERTICAL SOUNDER).

      HIRS/2 channels:

                                      under partly cloudy skies
