Abstract:

The results of the UV-B radiation monitoring carried out with UVB-1 pyranometer and Brewer spectrophotometer (MKIV No. 049) at the TOR station of IAO SB RAS (Tomsk) in 2003-2007 are presented. It is shown that main contribution into the annual income of UV-B radiation falls on the warm season with maximum in June. There is a spring increase of daily income in the annual-average behavior of UV-B radiation in April with a subsequent attenuation to the beginning of May, as well as fluctuations (10-15-day period) in daily income with typical peaks during summertime. Maximal variability in spectral behavior was observed in a 295-310 nm range, (Haggis band), which varies from year to year.
