20 October 2006On the use of quantitative diurnal cloud information for the calculation of daily UV dose maps over Europe
The KNMI/ESA Tropospheric EMission Internet Service (TEMIS) publishes daily forecasts of the clear-sky UV index
for today and 8-days ahead and analyses of the daily UV dose of yesterday and before. Near-real time ozone satellite
observations are used to account for the variations in UV radiation as a function of the overhead ozone column. The daily
UV dose depends critically on the assumptions that are made for the cloud correction factor. Cloud cover fraction is the
most uncertain parameter for day-to-day variations in the daily UV dose under non-overcast cloud conditions. The cloud
optical thickness is the most important parameter determining variations in daily UV dose for overcast situations. A good
cloud mask is essential to identify cloud-free scenes. Still further improvements in the daily UV dose can be made,
including the inclusion of the diurnal variation in cloud optical thickness as well as corrections for aerosols.
