Abstract
Mesoscale meteorological modeling and air quality modeling are key tools to understand the changes in the urban environment when different changes in the urban morphology are performed. In this contribution we have used the WRF model (NCAR) which includes the Urban Canopy Model (UCM) to understand the changes in the urban local environment when different alternatives are implemented .In addition, CMAQ air quality model (EPA, US) is used to estimate the hourly concentrations in the urban area. Three alternatives have been run for the full 2008 and investigate the differences with the control base scenario. The results show high sensitivity to these changes in weather patterns such as temperature and turbulent fluxes like sensible and latent fluxes. Due to the high spatial resolution of the simulations, it is possible to have a detailed picture of the soil atmosphere exchange fluxes and understand the impact of different urban planning alternatives in the urban environment from a meteorological and air quality point of view.
