The radiometric calibration of the sensors on the Landsat se- ries of satellites is a contributing factor to the success of the Landsat data set. The calibration of these sensors has relied on the preflight laboratory work as well as on inflight tech- niques using on-board calibrators and vicarious techniques. Descriptions of these methods and systems are presented. Results of the on-board calibrators and reflectance-based, ground reference calibrations of Landsat 5 Thematic Mapper are presented that indicate the absolute radiometric calibra- tion of bands 1 to 4 should have an uncertainty of less than 5.0 percent. Bands 5 and 7 have slightly higher uncertainties, but should be less than 10 percent. The results also show that the on-board calibrators are of higher precision than the vicarious calibration but that the vicarious calibration results should have higher accuracy. Introduction The Landsat series of satellites provides the longest running continuous data set of high spatial-resolution imagery dating back to the launch of Landsat 1 in 1972. Part of the success of the Landsat program has been the ability to understand the radiometric properties of the sensors. This understanding has been due to the combination of prelaunch and post- launch efforts using laboratory, on-board, and vicarious cali- bration methods. The radiometric calibration of these systems helps characterize the operation of the sensors, but more importantly, the calibration allows the full Landsat dat...
