Sensor Summary Fact Sheet for Landsat 8 TIRS
Collection: Landsat
The Landsat program, originally known as the Earth Resources Technology Satellite (ERTS), was proposed in 1965 by the US Geological Survey(USGS) as a civilian satellite program. NASA started building the first satellite in 1970 and have launched 6 spacecraft successfully (Landsat 6 was lost at launch). In December 2009 all Landsat archive products were made available free to the public on the USGS website. | |

Satellite: Landsat 8
Landsat 8 carries the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS) data recorder. The OLI sensor includes two additional bands compared to previous Landsat missions: a coastal aerosol band and a cirrus cloud band. The TIRS sensor provides data in two bands with different wavelengths and is resampled to 30m from 100m acquisition resolution. All products are provided in the 16-bit data range and have improved radiometric and geometric performance. Landsat 8 is offset from the Landsat 7 orbit by 8 days giving a shorter revisit time between the two satellites. | |
