Abstract

The basic physical principles underlying three common techniques for the vicarious calibration of the post-launch performance of meteorological satellite sensor are briefly reviewed. The techniques considered are: (a) using 'radiometrically stable' desert calibration targets which yield relative degradation rates; (b) congruent path aircraft/satellite radiance measurements which yield absolute calibrations; and radiative transfer model simulation methods which yield absolute calibrations. The applications of the three techniques will be illustrated, using the visible and near-IR channels of the Advanced Very High Resolution Radiometer flown on the NOAA polar-orbiting operational environmental satellites as an example. The establishment of inter-satellite calibration linkages, and cross-satellite sensor calibration will be briefly mentioned.
