CEOS Instrument: Thermal Infrared Sensor




Instrument:TIRS
Agencies: NASA [Primary]
 USGS
Mission: LDCM
Status:Being developed
Type:Narrow-band channel IR radiometer
Description:Measures surface radiance and emittance, lands cover state and change (eg vegetation type). Used as multipurpose imagery for land applications
Spatial Resolution: 100m
Swath Width: 185 km
Wavebands: TIR 10.5um and 12um
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.
