A Microscale Dispersion Model For Carbon-Monoxide Emitted From Motor-Vehicles

The purpose of this study is to analyse the diurnal variability of CO concentration observations using different fitted statistical distributions. A simple microscale dispersion model was also used to predict the local effect of heavily-travelled roads on carbon monoxide concentrations measured at certain monitoring stations in the Thessaloniki basin. The model results were validated and compared with actual measurements. Comparisons are also presented among CO vertical concentration profiles observed in urban street canyons of Athens and estimates from semi-empirical models.
