The Landsat-5 (LS) satellite was launched on March 01, 1984 with thematic Mapper (TM) and has collected data for 23 years. Over this time, the detectors have aged, and its radiometric characteristics have changed little from the day it launched. The calibration procedures and parameters have also changed with time. Revised radiometric calibrations have improved the radiometric accuracy of recently processed data. A procedure has been developed to give users the ability to recalibrate their existing Level 1 (Ll) products without having to purchase and reprocess data from the U.S. Geological Survey (USGS). The accuracy of the recalibration is dependent on the knowledge of the prior calibration applied to the data. The "Work Order" file, included with standard National Land Archive Production System (NLAPS) data products, gives parameters that define the applied calibration. These are the Internal Calibrator (IC) calibration parameters or the default prelaunch calibration.
