Algorithm for Mathematical Modelling of the Solar Radiation Transport in the Atmosphere-Ocean System with Frenel's Surface

A solar radiation transport in the atmosphere-ocean system is simulated as the radiation transfer in two-media slab with air-water dividing interface, reflecting and refracting of radiation on Frenel's law. The contributions of the straight sun irradiance and the multiple scattering background solar radiation in atmosphere are separated. The influence of the reflecting underlying dividing border and of the ocean as the scattering medium is evaluated by influence functions method.
