|Abstract:||The method for modelling surface UV radiation basically consists in using a standard radiative transfer code (UVspec) and in exploiting various sources of information to assign values to the parameters influencing the surface UV radiation. GOME, TOMS or TOVS data are used for the total column ozone. The tropospheric aerosols are taken into account by using observations at ground meteorological stations and the surface altitude by means of a digital elevation model. METEOSAT or MSG is used to derive cloud optical thickness and surface UV albedo. In this way, a climatological data set of erythemal daily doses over Europe, starting in January 1984 has been generated. The possibility of providing the UV information in principle anywhere and anytime has been and is exploited in impact studies. For example, the modelled UV data have supported a study on the influence of UV on the codfish population strength in the northern Atlantic (UVAC project). At JRC, the method is used in a human UV exposure model to estimate doses received by an individual, according to his/her activities and behaviour. Data were delivered to external partners to support other impact studies such as UV effects on crop yield, exposure of schoolchildren or vitamin D deficiency assessments. Results were also compared with ground measurements at a number of stations and included in studies of local UV conditions. With direct MSG data acquisition, a version of the processor was developed to generate near-real time UV index maps over Europe.|
