5.  Estimation of the UV Index climatology - examples

Operational forecasting of the UV Index gives information about its short-term changes in given the forecast region. However, the temporal and geographical variation of the UV-Index are important for people moving or travelling to different climatic conditions where their home experiences with UV radiation cannot be used. This concerns tourism in subtropical and equatorial regions in particular.

Figures 3 6 give a general overview of how the UV Index varies on clear days during the year and during the day at different geographical latitudes. The figures have been produced from the model developed at the University of Veterinary Medicine in Vienna using ozone observations from satellites (NASA/EPTOMS, 1996-1999).
