THE COUPLED CHEMISTRY-METEOROLOGY MODEL BOLCHEM: AN APPLICATION TO THE AIR POLLUTANTS LEVEL IN THE PO VALLEY (ITALY) HOT SPOT

We present the model performance of the online Coupled Chemistry-Meteorological Model BOLCHEM on seasonal period in an air pollution hot spot. The simulation domain is the Northern Italy where a large amount of agricultural, livestock, industrial activities are present, together with big city, as Milan, Turin and Bologna. Simulated surface concentration of Particulate Matter (PM 10 and PM 2.5 ) have been compared with measured concentrations at Airbase Stations for a winter period, while for the summer period also Ozone (O 3 ) has been considered. Results show that the model well reproduces observed concentrations, with similar correlation coefficient for particulate and ozone.
