Abstract

In this work, the climatological data (surface and upper-air) collected in the Greater Athens Area (GAA) for the period 1974–1990 was analysed. Based on this data and the air quality data collected for the period 1983–1990, the air pollution episodes were analysed and classified. The synoptic conditions during the episodes were classified too. It was found that the worst pollution episodes in Athens occur during days with critical balance between synoptic and mesoscale circulations. During these days, stagnant atmospheric conditions occur in the area. For two representative cases, model simulations were performed with mesoscale and regional atmospheric models. Model results compare quite well with observations. With these simulations, some critical points which must be taken into account in air pollution studies in the area of Athens were pointed out. Dispersion calculations in the area are under way.
