Measurements of some air pollution species in a rural station located near Antalya (36.47N, 30.34E) on the eastern Mediterranean coasts revealed high concentrations during the years 1992 2000. Since the area is free of any source of pollution, it is believed that such high concentrations of various pollution species are transported from other regions, such as Eastern or southeastern Europe. Long range transport of European air pollution to the Eastern Mediterranean region has been investigated during the episodic period 26 29 August 1998. Meso-scale Meteorological Model, MM5 was applied to forecast the hourly general circulation conditions and hourly 3 and 2 dimensional meteorological variables. Air mass backward trajectory simulations were also predicted by MM5/RIP and HYSPLIT models. Consequently, three main sectors of air mass trajectory originated from Europe were found. MM5 model outputs were used in the three-dimensional Eulerian photochemical model CAMx to simulate the concentration deposition and the long range transport of the air pollution species PSO 4 2- and SO 2 . CAMx air quality model simulations have revealed a great agreement with the air mass trajectory simulations produced by HYSPLIT and RIP/MM5 models and have demonstrated that sulfate transport from central and southeastern Europe to the eastern Mediterranean has two distinguished paths. The modeling system which is used for the first time in Turkey exhibited a high performance. Keywords: Long range air pollution transport, backward trajectory, MM5, CAMx, HYSPLIT.
