The Thermal InfraRed Sensor (TIRS) is one of the instruments on the Landsat Data Continuity Mission (LDCM) satellite. It will continue the archive of thermal imaging and support emerging applications such as evapotranspiration rate measurements for water management. TIRS is being built by NASA GSFC and has a three-year design life. In February 2012, TIRS was shipped from GSFC to Orbital Sciences Corporation in Gilbert, Arizona to be integrated with the LDCM spacecraft. TIRS operates in a pushbroom mode to create images in two IR bands, centered at 10.8 and 12.0 microns, over a 185 km swath with a 100 m spatial resolution. The TIRS design includes cryogenically-cooled QWIP detector arrays and a steerable mirror to choose among 3 views: nadir for Earth observations, on-board warm blackbody for calibration, and deep space for calibration. The TIRS data will be registered to the OLI data to create radiometrically, geometrically, and terrain-corrected 12-bit LDCM data products.
