Abstract:The post-launch degradation of the visible channel (≈0.67-0.71 m) of the High Resolution Infrared Radiation Sounder (HIRS) flown on the NOAA14 spacecraft has been determined, using a south-eastern Libyan desert site (21-23° N, 28-29° E) as a radiometrically stable calibration target. The annual degradation rate is observed to be 0.71 (±0.25)%. The relative degradation thus determined has been rendered absolute using the visible channel (channel 1; ≈0.58-0.68 m) of the Advanced Very High Resolution Radiometer (AVHRR) on the same spacecraft as a calibration reference.
