Paper Abstract

The method combines the use of a standard radiative transfer code (UVspec) and various sources of information on the influencing parameters to map surface UV radiation. GOME, TOMS or TOVS data are used for the total column ozone. The cloud optical thickness is estimated using METEOSAT/MVIRI data. Other influencing factors taken into account include tropospheric aerosols, snow cover and surface elevation. The resulting products are maps of surface dose rates and daily doses, covering Europe with a spatial resolution of 0.05 deg. Because the method is using METEOSAT the cloud optical thickness can be estimated every half-hour. This allows quantifying how well doses can be reconstructed from one or a few cloud images per day. The method is now being used to reconstruct the surface UV conditions during the last 10 to 15 years, in particular to support a study on the effects of UV radiation on marine biology in the Northeast Atlantic. Initial results for the month of March, from 1990 to 1999 are presented. Their validity is discussed with respect to the consistency of the input data during this period. A scheme to deal with drifts in METEOSAT sensitivity is presented.
