Abstract
A pilot study was performed in May 1993 concerning photooxidants in the Greater Athens Area, including both experimental and modelling work. The highest ozone and PAN concentrations (about 130 ppb and 6 ppb respectively) were observed at the northern suburbs of Athens. At the eastern part of Attica peninsula the low ozone (maximum observed about 70 ppb) and NO{sub x} levels indicated the absence of precursors in the area. According to the predictions of a three-dimensional mesoscale model, during a pollution episode day (22nd of May, 1993) the wind field over Attica was the combined result of a weak synoptic flow and three see breeze cells, developed over Saronikos Gulf, at Elefsis bay (west part of Attica peninsula) and at Mesogia plain (the east part of Attica peninsula) respectively. For the same day of the campaign the ozone, NO{sub x} and PAN concentrations predicted by the Urban Airshed Model are in rather promising agreement with the observations, although the emission inventory used was based on yearly totals of emissions only.
