Study of regional background air pollution over Europe using numerical models

Abstract

The purpose of this thesis is to study the photochemical pollution over Europe using the air quality model CAMx coupled offline with the regional climate model RegCM3 focusing on ozone and the impact of chemical lateral boundary conditions and emissions on ozone levels and variability. Within this framework four simulations were carried out by CAMx using various chemical lateral boundary conditions and anthropogenic emission scenarios. The ability of the modeling system to reproduce the spatial and temporal variations of surface ozone concentrations for the period 1996-2000 was evaluated by comparing models results with observational data from the EMEP network. Furthermore, the impact of chemical boundary conditions on ozone levels and variability was evaluated by implementing constant and varying chemical boundary conditions. Significant improvement was found in areas near the north and northwest boundaries of the domain as a result of using varying chemical boundary conditions from t ...
