Evaluating the Influence of Regional Gridded Emissions Distribution on Air Quality Simulation

The aim of this work is the assessment of changes in modelled regional air quality, by the comparison of the EMEP inventory vs. the application of a regional inventory based in a mixed top-down and bottom-up methodology over the NW of the Iberian Peninsula. Air quality simulations were carried out with the CHIMERE model for an ozone episode in 2008. Comparison against measurements using the Delta Tool show better scores for the regional inventory daily maxima 8 and 1 h ozone simulation results.
