2 Outline Introduction Motivations Field of investigation Experiment n. : Relax Flux - RF Outcomes Outlook 8 March, Air Quality Conference, Garmisch P. (Germany)

3 Purposes of SuperSito project Motivations Field of investigation... for epidemiological studies The air concentration of PM mass is the parameter that has been most closely linked to health effects Both fine and coarse particles show a link to health effects, although on different time scale exposure... for policy makers Great potential exists for the application of air pollution mitigation strategies to contribute to climate policies Research Findings in support of the EU Air Quality Review, 8 March, Air Quality Conference, Garmisch P. (Germany)

4 Tasks we are focusing on Motivations Field of investigation First step of a comprehensive evaluation of -D air quality modeling system NINFA/AODEM over Northern Italy Prediction of particulate matter concentrations and aerosol optical properties are compared with both ground-based and satellite measurements Basic statistics are calculated for pointing out model s strength and weakness 8 March, Air Quality Conference, Garmisch P. (Germany)

5 Experiment n. : Relax Flux - RF The modeling system NINFA/AODEM NINFA is based on the chemical transport model CHIMERE (Bessagnet et al., 8) driven by COSMO-I, the meteorological Italian Limited Area Model, (Steppeler et al., ) boundary conditions are provided by Prev air data ( emission input data are based on regional (INEMAR), national (ISPRA) and european inventory (MACC) 8 March, Air Quality Conference, Garmisch P.
