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.

Evaporation and Transpiration
Read moreMuch of the water that soaks into the soil from irrigation or rain ultimately returns the the atmosphere as water vapor through direct evaporation from the surface or by transpiration through plant leaves as the plants use the water for growth and seed production. This loss cools the surface and plant canopy just like the evaporation of sweat cools our skin. A cool field in an arid area indicates water use by irrigation. Using the surface temperatures measured by satellites, and some additional information, water resource managers can determine the rate at which water is used in a farm field. ||
