Conclusions

The UV insolation at Paramaribo is surprisingly constant over the year with typical maxima of UV Index of 13 or 14 on a cloudfree day. The UV Index as calculated with a regression method based on the ozone column and sza as applicable in mid-latitudes (AES, Ontario, Canada; Burrows et al., 1994) is systematically smaller than the observed UV Index. Different regression models are needed for the UV Index-Total ozone relationship for different latitude bands and/or sites.
