Photochemical pollution in the Windsor Quebec City Corridor (WQC) is a topic of concern as it is the region of Canada where ozone excursions above the maximum acceptable level occur with the highest frequency. It is also one a heavily populated area and a region important for Canadian agriculture. Long range transport has been estimated to account for as much as 60% of the high levels of ozone in southern Ontario. However the extent of the long range transport contribution within the WQC is still an open question that the authors wish to investigate. Their approach consists in studying the climatology of ozone given by a regional climate model for the north eastern part of the WQC. Thus tey are in the process of adapting the Canadian Regional Climate Model (CRCM) by adding a chemical module. The module consists of the photochemical mechanism of the Acid Deposition and Oxidant Model (ADOM), anthropogenic and natural emissions of hydrocarbons and nitrogen oxides and a dry deposition parameterization. The CRCM is a three dimensional model resulting from the coupling of the subgrid-scale parameterizations of the Canadian General Circulation Model (GCM-II,1) with MC2 (Mesoscale Community Compressible), a regional model using semi Langrangian and semi implicit transport schemes. The CRCM is driven by the GCM-II through a one way nesting procedure. As the application of the model will involve either long or numerous runs, it has been chosen to introduce the chemical module on line. The presentation will focus on a detailed description of the model. Available results will also be discussed.
