Abstract

Preliminary results of a sensitivity analysis of the post- launch calibration of the visible (channel 1; approximately equals 0.58 - 0.68 micrometer) and near-infrared (channel 2; approximately equals 0.72 - 1.1 micrometer) channels of the advanced very high resolution radiometer using the southeastern part of the Libyan desert (21 - 23 degrees N; 28 - 29 degrees E) as a radiometrically stable calibration target are presented. It is observed that small but finite changes in the Lambertian surface albedo, and in the contributions of gaseous and particulate scattering and absorption to the upward radiation at the top of the atmosphere lead to changes in the relative degradation rates of comparable magnitude.
