Abstract
The relationship between variations in the values of surface ultraviolet radiation in the wavelength range 280-320 nm and the state of the underlying surface is analyzed. For this purpose, a homogeneous series of UV-B radiation data obtained at the TOR-station of IAO SB RAS from 2004 to 2016, satellite data on TOC, AOT data from AERONET network, and the data on total cloud cover from the meteorological site of IMCES SB RAS were used. It is shown that the contribution of the underlying surface albedo to increase in the UV-B radiation is 4-8% on average for TOC = 300-400 DU and 9-13% for TOC = 400-500 DU subject to stable snow and the solar zenith angle from 52° to 68°.
