Abstract:
This article presents information about the importance of biologically active ultraviolet radiation from the Sun (UV-B), which is the subject of long-term (2011- 2019) monitoring at the National Institute of Geophysics, Geodesy and Geography – Bulgarian Academy of Sciences. Information on the technique, the units of measurement and the summarized characteristics of the diurnal and seasonal course of UV-B are presented. On the basis of simple physical concepts of absorption of UV- radiation in the Earth’s atmosphere is proposed an empirical model for forecasting its integral value, depending on the daily weather and season. According to the recommendations of the World Health Organization, a method for real-time notification of the permissible stay in the sun has been developed. In conclusion, the information on UV-index, which is provided on the website of the National Institute of Geophysics, Geodesy and Geography – Bulgarian Academy of Sciences is described in detail.
