The UV Index ranks the amount of UV radiation on an 11-point scale. Seeking shaded areas and generously applying sunscreen are some of the best ways to protect your skin from UV rays.

The sun’s rays become stronger as you move south, and in the tropics, the index can rise to 14 or higher. However, excessive exposure to solar UV radiation can result in harmful effects to the skin and eyes. If you must be out in the sun, especially between 11am and 3pm when the UV index levels are highest, the following simple protective measures can help to minimise the effects. Use sunscreen (at least SPF 30) Use an umbrella and seek shade Državni hidrometeorološki zavod prognozu UV indeksa izrađuje na temelju rezultata globalnog modela ICON Njemačke službe za prognozu vremena - DWD (Deutscher Wetterdienst).Proračun uključuje rezultate prognoze ozona (KNMI) i prognoze optičke debljine sloja aerosola (ECMWF) koji se dostavljaju u sklopu Copernicus Atmosphere Monitoring Service (CAMS). 2020-08-18 Season: The UV Index is highest in spring and summer. It goes down in the fall and is the lowest in the winter.

The UV Index scale used in the United States conforms with international guidelines for UVI reporting established by the World Health Organization ExitLearn how to read the UV index Scale to help you avoid harmful exposure to UV radiation. The UV Index is accompanied by recommendations for sun protection and is a useful tool for planning sun-safe outdoor activities. Ozone depletion, as well as seasonal and weather variations, cause different amounts of UV radiation to reach the Earth at any given time.

The UV index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the earth's surface. It cannot be simply related to the irradiance (measured in W/m 2) because the UV of greatest concern occupies a spectrum of wavelength from 295 to 325 nm, and shorter wavelengths have already been absorbed a great deal when they arrive at the earth's surface.

The UV data is collected continuously by detectors that respond to UV in a manner similar to human skin and updated in this chart every minute. Use the chart above to find out what the UV index is at our measurement sites and what time the UV index will be at its highest.

The Indeks Ultraviolet (UV Index) Indeks UV adalah angka tanpa satuan untuk menjelaskan tingkat paparan radiasi sinar ultraviolet yang berkaitan dengan kesehatan manusia. Dengan mengetahui UV index kita bisa memantau tingkat sinar ultraviolet yang bermanfaat dan yang dapat memberikan bahaya. Setiap skala ada UV Indeks setara dengan 0.025 Wm 2 The ultraviolet (UV) index is a scale that represents the intensity of UV radiation produced by the sun. The index was originally created by Canadian scientists in the early 1990s and has since been adapted for use throughout the world. The UV Index also recommends “Actions to Take”—such as wearing sunscreen and a hat—to avoid getting UV-index. UV-index är ett mått på hur stark solen är och ger en signal om hur mycket skydd du behöver. Årstid och tid på dygnet styr förstås hur stark strålningen är och därmed indexet.

In countries close to the equator UV-index är ett värde som visar styrkan av den skadliga delen av solens UV-strålning när den är som starkast. Det är den vanligen mitt på dagen. UV-index varierar framför allt med årstiden och tiden på dygnet. UV Index worldwide. The UV-Index.

The UV index is defined as the effective irradiance on a horizontal surface obtained by integrating the spectral irradiance weighted by the Commission Internationale de l’Eclairage reference action spectrum for UV-induced erythema on the human skin up to and including 400 nm and normalized to 1.0 below 298 nm (see also Fig. 2).
