Abstract
An algorithm for reconstructing the Earth’s surface reflection coefficients from the data of MODIS satellite measurements is considered. For six channels of the MODIS device in the visible and near-IR ranges, the influence of a 10% error in the assignment of the aerosol and molecular extinction on the accuracy of reconstructing of the Earth’s surface reflection coefficients is estimated. A comparison of this error with the error of reconstructing the reflection coefficient for a surface area in the Tomsk Region by the suggested algorithm and the algorithm MOD09 is performed. Results of comparison show that the error in assignment of the input optical parameters can be the main source of the error of the correction algorithms for wavelengths 0.4–0.85 μm. For the channel centered at 1.25 μm the error of the algorithms is much greater than the error caused by a 10 % error of assignment of the optical parameters.
