Résumé
Air quality assesment for photochemical pollution makes use of air quality to predict future concentrations will prespond to emissions controls. Given the complexity of the combined physiochemical phenomenen leading to ozone and other polluants formation, air quality models represent the best theoretical approach currently available to understand the response of the atmosphere and especially of ozone leveles to different air pollution control measures. However, if their ability to reproduce and describe historical photochemical pollution episodes has been demonstrated , the robutness of the predicted air quality resulting from emission changes still has to be proven. It is known that to get an effective control of air quality, it is necessary to include the influence of all anthropogenic sources such as vehicle emissions in a street canyon, in addition to any present industrial sources. The objective of this study is to simulate the polluants transport and transformation in the city of Kozani during a summer week period, as well as to assess the influence of meteorology conditions, topography and the small scale physiocochemical effects of a street canyon, on the performance of local/meso scale model simulations by the aid of the mesoscale model TAPM .
