[abstract] The UVB erythemal irradiance measurements obtained at Thessaloniki, Greece (40oN) are analysed. The variability of the erythemal irradiance is compared with that of the total columns of ozone and SO2. It is shown that these two factors explain about 50% and 26% respectively of the total variability of the erythemal irradiance. The influence of the reduced total ozone levels observed during the last 4 years on the increase in the solar UV irradiance at 305 nm is also presented. Finally, a comparison between stations with different air pollution levels under clear skies shows that air pollution can significantly reduce the UVB dose levels received at the ground.
