Monte Carlo simulation of specific features of radiation regime in water layer caused by clouds and roughness of the water surface

The paper presents the results of Monte Carlo simulation of the radiation regime in the system “atmosphere - water layer”. The radiation reflection and refraction at the sea surface is simulated with the help of the Fresnel formulas. The facet model is used to describe the sea surface roughness. The vertical stratification of the actinic flux, radiance and angular distributions of the solar radiation are investigated.
