Solar Ultraviolet spectrophotometric measurements are used to provide estimates of the total columnar sulphur dioxide concentrations over urban, semirural and industrial areas of Thessaloniki in Northern Greece. The systematic observations of the SO 2 column represent an estimate of the impact of anthropogenic sulphur dioxide on the solar radiation received at the surface of the earth. The measurements span over a period of more than ten years, giving the longest presently available record of the total columnar SO 2 in Europe. Total columnar and ground-level SO 2 measurements display an annual variation with maximum concentrations to occur in the winter period of the year. Finally, by combining the simultaneous columnar and surface SO 2 measurements, we obtain estimates of the height of the polluted layer and mean residence time for sulphur dioxide over Thessaloniki basin.
