The spatial resolution of 3-Dimensional numerical model has a very important influence on the model result. The land-use and orographic effect is also influenced by the spatial resolution of the model. A large errors in model performance are produced depending on the terrain complexity. In this study we performed Air Quality Forecast model (AQF) simulation and analyzed the change in the ozone concentration depending on spatial resolution at small and medium-sized mixed areas with urban and rural area types. As the result, improving the spatial resolution improved the simulation of the downward trend of ozone at night. This was mainly due to improvement of local concentration contaminants at fragmented grid. In the case of wind speed, the model with high-resolution shows better agreement with observation at night.
