Sultangazin (Space Research Institute, Kazakhstan) ``Some Mathematical Problems of Atmospheric Correction on Remote Sensing Imagery'' ¡ãAbstarct¡ä The remote sensing from a satellite or an airborne platform of the land or the sea surface in the visible and near infrared is strongly affected by the presence of the atmosphere on the Sun-target-Sensor path. In the present research, we consider some numerical methods of inverse problems for the calculation of atmospheric effects in remote sensing of the ground and oceans reflectance. The proposed method is based on the spherical harmonic in the solution of the radiation transfer equation in atmosphere with the inhomogeneous land surface. The developed method also consists in restitution of the optical characteristics of atmosphere and land surface on the using of radiance measured by the sensor. The method is established for general case of a reflection on the Earth's surface for multiple scattering.
