Thematic Mapper thermal infrared calibration
Abstract
TM band 6 data from Landsat-4 and Landsat-5 are analyzed by correcting the observed radiance for the spectral characteristics of the sensor, along with atmospheric propagation parameters derived from LOWTRAN models. The resultant surface radiance values or surface temperatures are compared to surface temperatures derived from underflight and ground truth data. Correlation of these data indicate that significant systematic error is evident in the satellite-derived surface temperatures. Evaluation of the expected error introduced by the LOWTRAN modeling technique results in compensation of some of this systematic error. The remaining error indicates that the satellite internal calibration, specifically the sensor gain, corrections are not completely compensating for gain shifts.
