Index The specified UV Index values serve as a benchmark for a typical atmospheric condition at each respective location. UV The UV Index does not drop below 11 at any point in the year, which means that there is a constant and extreme risk of harm. Because of modern westernized fashion and cultural habits, it is very common for people of all skin tones to dress in clothing that exposes larger portions of their skin to the sun in an attempt to achieve the perfect tan. Typical UV Index values for a range of cities worldwide are specified for the 21st of each month based on calculations with the radiation transfer model STAR.

The UV index is designed as an open-ended linear scale, directly proportional to the intensity of UV radiation, and adjusting for wavelength based on what causes human skin to sunburn. Slip on a shirt, slop on sunscreen and slap on hat! [5] This linear scale is unlike other common environmental scales such as decibels or the Richter scale, which are logarithmic (the severity multiplies for each step on the scale, growing exponentially). An index of 10 corresponds roughly to midday summer sunlight with a clear sky when the UV index was originally designed; now summertime index values in the tens are common for tropical latitudes, mountainous altitudes, areas with ice/water reflectivity and areas with above-average ozone layer depletion. - Please bookmark this page (add it to your favorites)- If you wish to link to this page, you can do so by referring to the URL address below.
