Abstract
A comparison of calculation and measurement results of downward solar radiation fluxes at the Earth's surface, made in the cloudless atmosphere in summer of 2010–2012, in the background area of the boreal zone of Siberia (Tomsk) is presented. The comparison is made taking into account instrumental accuracy and errors in determining the atmospheric characteristics. To set the aerosol optical characteristics, ground-based photometric measurements data, obtained at the Tomsk site of AERONET network were used. It is shown that the relative differences in the simulated and experimental values of the fluxes of direct and total radiation is on average less than 1% and 3%, respectively.
