AbstractA consistent, continuous record of post-launch calibration and performance of the Advanced Very High Resolution Radiometer (AVHRR) onboard the polar orbiting NOAA-7, NOAA-9, and NOAA-11 satellites, spanning the period from 1981 to present, has been produced under the NOAA/NASA AVHRR Pathfinder project. The relative degradation rates for the AVHRR visible (channel 1; ≈0.63μm) and near-infrared (channel 2; ≈0.83μm) channels have been established using the southeastern part of the Libyan desert as a calibration target. The degradation rates are of the order of a few percent per year for both channels. Channel 2 is observed to degrade at a faster rate than channel 1 for the AVHRRs on NOAA-7 and NOAA-11; this trend is reversed for the AVHRR on NOAA-9. The degradation rates obtained in the present study are comparable to results obtained by other, independent methods of post-launch calibration.
