Abstract

A comprehensive modelling system taking into account emission, transport, dispersion, deposition and chemical transformation processes of gaseous pollutants has been used to simulate an ozone episode over the Piemonte Region in Northern Italy. A meteorological pre-processor (SURFPRO: SURrfaceatmosphere interFace PROcessor) has been developed and applied in order to estimate the parameters used to define the status of the lower part of the atmosphere commonly called the Planetary Boundary Layer (PBL). The vertical exchanges between surface and lower atmospheric layers are defined estimating momentum, heat and moisture turbulent fluxes and PBL depth. The capability of the atmosph
