THE CEOS DATABASE : Missions, Instruments and Measurements
Full Name Thermal Infrared Sensor - 2 Status Approved
Instrument Agencies NASA, USGS Maturity
Instrument Type Imaging multi-spectral radiometers (vis/IR) Geometry Push-broom scanning
Instrument Technology Narrow-band channel IR radiometer Sampling Imaging
Data Access Open Access Data Format GeoTIFF
Measurements and Applications Measures longwave thermal infrared surface emittance, land cover state and change. Used as multipurpose imagery for land applications. TIRS-2 will adhere to the Landsat 8 TIRS instrument performance specifications, but will be built to NASA Class-B instrument standards (including a 5-year design life).
