Clear-sky UV index forecast

The clear-sky UV index is a measure for the effective UV irradiance (1 unit equals 25 mW/m2) reaching the Earth's surface. The clear-sky UV index is based on the CIE action spectrum for the susceptibility of the caucasian skin to sunburn (erythema) and it is valid for cloud-free conditions at local solar noon, i.e. when the sun is highest in the sky. Forecasts are provided for today and the next few days.
