Since UV solar radiation plays an important role in many processes in the biosphere, including humans and may be very harmful if UV exposure exceeds �safe� limits, the knowledge of biologically effective UV radiation doses and their geographical distribution and climatology in Europe is crucial for Europe’s population, which is the main end user of the Action. The main objective of the Action is to advance the understanding of UV radiation distribution under various meteorological conditions in Europe in order to determine UV radiation climatology and assess UV changes over Europe.
