Resumen
- We examine the ability of a modelling system to forecast the formation and transport of ozoneover Catalonia, at the NE of the Iberian Peninsula. To this end, the Community MultiscaleAir Quality (CMAQ) modelling system developed by the United States Environmental ProtectionAgency (US EPA) and the PSU/NCAR mesoscale modelling system MM5 are coupled to a newemission model, the Numerical Emission Model for Air Quality (MNEQA). The outputs of themodelling system for the period from May to October 2008 are compared with ozone measure-ments at selected air-monitoring stations belonging to the Catalan Government. Results indicatea good behaviour of the model in reproducing diurnal ozone concentrations, as statistical valuesfall within the EPA and EU regulatory frameworks.
