Abstract:

This study aims to investigate the day by day relationship between mesoscale circulation and air quality over the Metropolitan Athens for a period of thirteen years spatially and seasonally. Eleven distinct mesoscale patterns are remarkable based in a formulated methodology based on surface and upper air wind measurements. The air quality conditions were attributed into seven distinct classes for five main pollutants namely, O3, NO2, SO2, CO and Black Smoke (BS). It was found that the severe and bad air quality conditions over the Metropolitan Athens area are mainly associated with weak southerly flows. The most serious pollution problem in AMA is attributed to O3 in the warm period when is favoured even by intense northerly flow. Due to the complex topography and the distribution of industrial and anthropogenetic activities in the examined area, the relationship between the air pollutant’s concentration and mesoscale air circulation presents important spatial characteristics that are further investigated.
