National Italian integrated atmospheric model on air pollution: Sensitivity to emission inventory

Sensitivity of MINNI's Atmospheric Modeling System has been tested over year 2005 using two different emission datasets, the National Emission Inventory (top-down approach) and the GAINS-Italy emission estimates (bottom-up approach). Detailed analysis has been carried over the Po Valley region for NOx and PM10 concentrations, since their EU limit values are often exceeded. NOx and PM10 results have been compared to available measurements showing that emission input variation has a detectable influence on simulated concentrations. The variations in model performance in relation to the variation of emission inventory have been analyzed at background urban, suburban and rural monitoring stations.
