TIRS (Landsat 8 Thermal Infrared Sensor)
Thermal Infrared Sensor on Landsat 8, built at NASA Goddard, measuring land surface temperature in two thermal infrared bands from 10.6-12.51 um at 100 m native resolution, resampled to 30 m in Landsat products.
TIRS is the Thermal Infrared Sensor on Landsat 8, built by NASA Goddard Space Flight Center to measure land surface temperature in two thermal infrared bands [1][2]. Its Band 10 range is 10.6 to 11.19 um and Band 11 range is 11.50 to 12.51 um, covering 10.6 to 12.51 um across the two thermal bands [3]. TIRS data are acquired at 100 m native thermal resolution and resampled to 30 m in Landsat products [1][3]. The instrument is used in Landsat Collection 2 Surface Temperature products for land-surface-temperature and emissivity work [4]. Landsat 8 calibration notices record the TIRS stray-light correction and advise against Band 11 split-window use for quantitative retrievals, so quantitative surface-temperature workflows should account for that Band 11 limitation [5]. Landsat 9 TIRS-2 is a distinct later instrument and should not be conflated with Landsat 8 TIRS [2].

Landsat Collection 2 Surface Temperature is derived from Landsat thermal infrared observations; Landsat 8 TIRS supplies Bands 10 and 11 at 100 m native resolution.
