Spectral/Frequency Information Wavelength Keyword: Infrared > Thermal Number Channels: 19 Spectral/Frequency Coverage/Range: 4 - 15 micrometers Related Data Sets View all records related to this instrument Description 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
