Algorithm to Mathematical Modelling the Radiation Transfer in the Atmosphere-Ocean System with Frenel's Dividing Border

The sun radiative field in the atmosphere-ocean system with Frenel's dividing border is calculated by the influence functions method. The models of the calculations structure with a division of an influence of the straight sun irradiance and diffusional atmospherical background on ocean radiation and on radiative ex-change between ocean and atmosphere. The computation algorithm is described.
