Abstract
The paper represents the results of the correlation analysis of observation series of total ozone and ultraviolet radiation in 300-315 nm wavelength band for temperate zone stations of Russia and Canada (Northern hemisphere, 50 N and higher) in the boreal forest zones. It is shown that the ozonosphere is the primary modulator of the biologically active UV-B radiation spectrum part in this climatic zone. Radiation amplification factors of solar UV-B spectral region are determined. It is demonstrated that 20% of total ozone depletion leads to the increase of the dose of the shortwave part of solar UV-B radiation more than twice relative to its climatic norm.
