Land surface temperature

Land Surface Temperature (LST), also referred to as skin temperature of the land surface, is a key variable in the determination of land surface-atmosphere processes from local to global scales. It has been identified as one of the most important environmental data records and is widely used in meteorological, climatological, hydrological, ecological, biophysical, and biochemical research . LST, usually measured by the ground-based, airborne and space-borne remote sensing instruments, is the aggregated radiometric temperature of all surface components including soil, vegetation and other land surface components within the field of view of the sensor. My research focuses on improving the measurements of LST from different platforms.
