Atmospheric correction of LANDSAT TM thermal band using surface energy balance

Abstract
Thermal infrared (IR) data of Landsat Thematic Mapper (TM) have been hardly used during the last decade, probably due to the difficulties met when trying to correct them for atmospheric effects. A new method for correcting these data has been designed, based on surface energy balance estimation of known wet and dry targets included in the TM image to be corrected. This method, only using the image itself and local meteorological data, has been tested and validated on various surfaces: agricultural, forest and rangeland. The RMS error on corrected temperatures is of the order of 1°C.
