Calculations of self-shading for an instrument measuring upward irradiance were conducted with a Monte-Carlo radiance transfer algorithm. The algorithm included Cox-Munk wave- slope probability function and simulation of diffusion on sea-bottom allowing incorporation of rough and/or shallow sea in the simulations. The effect of the self-shading phenomenon was calculated in the function of instrument radius, sea-water absorption, surface roughness (depending on assumed wind velocity up to 15 m/s) depth of the instrument, its height over bottom and bottom albedo (both diffusive and reflective one).
