In fact anticyclonic conditions in Northern Italy easily lead to temperature inversions of about (300400) m and give rise to

In this perspective, the CALGRID-CALMET modelling system has been applied to the Milano metropolitan area and its suburbs, a very industrialised and populated region in the Po Valley. A simulation domain of 100 x 100 km² has been considered and a summer period, characterised by high photochemical activity, has been selected. Hourly emissions have been derived by spatially and temporally disaggregated national inventories data, while standard upper-air and ground based meteorological data have been used as inputs to the CALMET pre-processor. The modelling system has been applied for the evaluation and comparison of different emission control strategies. Since the main source of pollutants in the area is actually traffic, the impact of cleaner fuels and cleaner cars has been investigated.

To improve air pollution modeling, 3D dust fields, produced by means of the DREAM dust forecasts, were integrated as boundary conditions into the mesoscale 3D deterministic Transport Chemical Aerosol Model (TCAM). A case study of the TCAM and DREAM integration was implemented over Northern Italy for the period May 15-June 30, 2007. First, the Saharan dust impact on PM10 concentration was analyzed for eleven remote PM10 sites with the lowest level of air pollution. These remote sites are the most sensitive to Saharan dust intrusions into Northern Italy, because of the absence of intensive industrial pollution. At these remote sites, the observed maxima in PM10 concentration during dust events is evidence of dust aerosol near the surface in Northern Italy. Comparisons between modeled PM10 concentrations and measurements at 230 PM10 s...

Consequently, in order to assess the comprehensive effects of photochemical pollution, not only ozone peak concentrations need to be examined, but also ozone exposures on "seasonal" scale need to be quantified.

The problem can be formalized as a multi-objective mathematical program, integrating local pollutant-precursor models and the estimate of emission reduction costs. Both aspects present several complex elements. In particular the source-receptor models, describing transport phenomena and chemical non linear dynamics, require deterministic complex modelling systems with ...
