Instrument:HIRS/3
Agency: NOAA
Missions: NOAA-16
 NOAA-17
 NOAA-15
Status:Operational
Type:Narrow-band channel IR radiometer
Description:Atmospheric temperature profiles and data on cloud parameters, humidity soundings, water vapour, total ozone content, and surface temperatures
Spatial Resolution: 20.3 km
Swath Width: 2240 km
Wavebands: VIS - TIR: 0.69 - 14.95 ?m (20 channels)
Technology: Narrow-band channel IR radiometer
Description: Radiometer operating in MWIR and TIR with many channels of bandwidth around 1 % in absorption bands of CO2 and H2O to retrieve temperature and humidity profiles in cloud-free or partially cloudy areas. Cross-nadir scanning for vertical profiling. A few tens of channels. Spatial resolution typically 10-20 km horizontal, ~ 2 km vertical (referred to the retrieved profile). Applicable in LEO and GEO.
