The relationship of the daily UV-B radiation with factors influencing it (total ozone content, cloudiness, and aerosol optical depth) is analyzed. For this purpose, a homogeneous series of UV-B radiation data obtained at the TOR-station of the IAO SB RAS from 2003 to 2016, as well as 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. The regression equations of the daily UV-B radiation variations depending on the changes in total ozone content under different cloudiness and air transparency conditions have been derived.
