Abstract

A radiative transfer model is developed for the calculation of ultraviolet (UV) fluxes in the atmosphere-ocean system. The radiative transfer equation for the atmosphere is solved by the modified discrete ordinate method. Obtained angular distribution of radiance at the ocean surface serves as a boundary condition for radiative transfer equation in the ocean. The latter is solved by the quasi-single approximation. The comprehensive models are used for the spectral dependencies of optical properties of the atmosphere and the ocean. Calculations of spectral irradiance within the 290 - 400 nm region have been carried out for different solar zenith angles and total amount of ozone inherent to high latitude regions. By convolution of irradiance spectra for the ocean with the phytoplankton action spectrum the UV dose rates have been obtained for different depths.
