Italian Agency for New Technologies Energy and the Environment Long Range Transboundary Air Pollution Convention TFIAM Meeting, Amiens, May, 10-12, 2004 The MINNI Project A 3 year project for the development of a National Integrated Modelling System Carried out under the leadership of ENEA in cooperation with ARIANET Project financed by ENEA and the Italian Ministry for the Environment (total investment 1,268 million Euros)

Ultimate Objectives : Italian Agency for New Technologies Energy and the Environment Long Range Transboundary Air Pollution Convention The MINNI Project - Development of emission Scenarios, for SO2, NOx, NH3, VOC, O3 e PM - Development of national/regional cost curves, analysis of the abatement costs, optimised cost allocation - Analysis of impact on environment and human health TFIAM Meeting, Amiens, May, 10-12, Analysis of pollutant transport, dispersion and multiphase chemical transformations - Development of deposition/concentration maps at national and regional level

Three different simulation models are integrated in a coherent framework: Italian Agency for New Technologies Energy and the Environment Long Range Transboundary Air Pollution Convention The MINNI Project Meteorological model (RAMS) Pollution transport and chemistry model (FARM) Integrated Assessment Model (RAINS-Italy) TFIAM Meeting, Amiens, May, 10-12, 2004

Transport and Chemistry Model FARM Italian Agency for New Technologies Energy and the Environment Long Range Transboundary Air Pollution Convention The MINNI Project TFIAM Meeting, Amiens, May, 10-12, 2004 Derived from STEM Model (Carmichael et al., 1998). Three-dimensional Eulerian model Acid pollutants are treated by means of the (Hov et al., 1988) chemical scheme Photochemical reactions are described by the SAPRC-90 chemical scheme Models-3/CMAQ Aero-3 module (Binkowski, 1999) used for PM Chemical boundary conditions are assigned by the EMEP Model
