Paper Abstract

The method for modelling surface UV radiation consists in using a standard radiative transfer code (UVspec) and in exploiting various sources of information (satellite and ground) to assign values to the influencing parameters. In particular, 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. The modelled UV data have supported the UVAC project on the influence of UV on the codfish population strength in the northern Atlantic. 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. 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. 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.
