Abstract

Thermal infrared data from the Thematic Mapper has been analyzed and methods of calibration developed that can reduce residual error to 0.9K (1 standard deviation). The instrument and its ground calibration and the methods of verifying radiometric performance on orbit are discussed. The substantial data uncertainty caused by the atmosphere is illustrated. The Enhanced TM is being built with an additional window to reduce condensation. Other instruments in preliminary design will have more and narrower spectral bands to expand the applications of radiometric thermal imagery on land and at sea. A detailed procedure for accurate reduction of raw data from the Landsat-5 thermal band is presented.
