About
Landsat 5 Surface Temperature comprises land surface temperature datasets derived from Landsat 5, the remote-sensing satellite that holds the Guinness World Record for the longest-running Earth observation mission. Over nearly 29 years of operation, ending in 2013, Landsat 5 orbited the planet more than 150,000 times and transmitted 2.5 million images of land surfaces worldwide. This product is derived from the thermal infrared channel (Band 6) of the Thematic Mapper (TM) sensor at 30-metre resolution. It is an important resource for monitoring urban heat islands, drought, vegetation stress and geothermal activity around the world.
