A simple method has been devised to produce daily doses of UV radiation from the solar total irradiation at ground level. The well-known HelioClim databases contain daily total irradiation for Europe since 1985. They are exploited to produce the EUROSUN database covering the period 1988-2007 for supporting analyses of effects on incidence of skin cancers through maps and exposure of individuals. Maps of 5-years average of monthly means of UV daily doses are made and compared to other maps of lower spatial resolution from the COST no726 project and from KNMI/ESA. The coincidences of features support the validity of the EUROSUN database in terms of spatial and temporal variability.
