AB - A comprehensive evaluation was conducted on annual 2005 WRF/CMAQ simulations over the southeast of England to identify the cause of model deficiencies and to determine if the model is suitable for policy applications. The model performance was characterised through operational, dynamic and diagnostic evaluations. For operational evaluations, the model results, downscaled from a horizontal grid resolution of 81km to 3km, were compared against the observations from 120 air quality monitoring sites measuring NO<inf>2</inf> and O<inf>3</inf> concentrations across the southeast of England. The predicted surface and vertical profiles of temperature, relative humidity and wind components were also evaluated, as was the predicted atmospheric pressure at mean sea level, which was compared with the synoptic scale charts. Demonstration of a number of model diagnostics was made possible through the use of 'Openair' (http://www.openair-project.org/), AMET (http://www.cmascenter.org) and through development of R scripts. These included time series plots, scatter plots, diurnal error plots, Taylor diagrams and statistical measures. The performance of WRF/CMAQ for 2005 showed that the model was able to capture seasonal trends, the magnitude of the observed meteorology, NO<inf>2</inf> and O<inf>3</inf>, and the partitioning of oxidant (NO<inf>2</inf>+O<inf>3</inf>). The analysis presented indicates that overall CMAQ represents O<inf>3</inf> concentrations well, although WRF over predicts wind speeds during the night and this has an impact on NO<inf>2</inf> and O<inf>3</inf> concentrations during this time. The dynamic evaluation showed that the model responds to changes in emissions of NO<inf>X</inf> and HC's and that these agree well with other results in the literature. Further sensitivity analyses between 2005 (typical UK weather) and 2008 (wet year) showed that
