Welcome to the AATSR/SLSTR Land Surface Temperature Portal

Land Surface Temperature (LST) is the radiative skin temperature of the land derived from solar radiation. It is a basic determinant of the terrestrial thermal behaviour, as it controls the effective radiating temperature of the Earth’s surface.

This site focuses primarily on LST derived from the Advanced Along-Track Scanning Radiometer (AATSR) instrument which is onboard of the European Space Agency's (ESA) Envisat satellite, and the upcoming Sea and Land Surface Temperature Radiometer (SLSTR), which is schedule for launch on the Sentinel-3 satellite in 2014.
