MODELING OF RADIATION CHARACTERISTICS IN OPTICALLY THICK LAYERS FOR REMOTE SENSING PROBLEMS

Boundary-value problem of radiation transfer in optically thick layers is considered while describing ocean, cloudiness, aerosol particle outbreaks, dust traces and other specific effects resulted from large fires (forest, peat-lands, in steppe regions, anthropogenic). Space and angular distribution...
