Forecast of the UV-INDEX worldwide: =================================== valid for 21.01.2021 midday The UV-Index gives the intensity of the solar biologically-effective ultraviolet radiation under consideration of the total ozone concentration, the absorption of the atmosphere, the sea level of the site and the time of the year. On basis of the UV-Index the sun burn time for clear sky is calculated for sensitive skin (photobiological skin type 1 or 2).
