TIRS
Thermal Infrared Sensor
Operational
Measures longwave thermal infrared surface emittance, land cover state, and change. Used as multipurpose imagery for land applications.n/a
TIRS-2
Thermal Infrared Sensor 2
Operational
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).n/a
CWFMS
Canadian Wildland Fire Monitoring Sensor
Being developed
Measurements are: Fire Radiative Power (FRP), hotspot locations, rate of spread, burned area mapping. Data products generated: 1) Fire maps, showing location, extent, and timing of forest fire events; 2) Fire characteristics, such as fire line intensity, rate of spread and fuel consumption; 3) Plume dynamics through smoke transport maps and plume heights; 4) Mass of carbon released into atmosphere.Multi-purpose imaging Vis/IR radiometer
