OBJECTIVES The LMDz-INCA climate-chemistry model is used to estimate the effect of transport emissions on the chemical composition of the troposphere at global scale. Up-to-date emission inventories (2000) and predictions (2050) are used for the transport and other anthropogenic emissions • SIMULATIONS • Resolution : 3.75° x 2.5° , 19 hybrid -p levels (up to 3 hPa) • Nudged simulations for current climate and 2003 meteorology with: • 2000 anthropogenic emissions • 2050 anthropogenic emissions for A1 scenario • 2050 anthropogenic emissions for B1 scenario • Emission datasets • ● Anthropogenic emissions =QUANTIFY final datasets (1°x1°) • ● Biogenic emissions = IPSL “ORCHIDEE” model outputs (2°x2°) QUANTIFY AC3 Workshop, August 2008, Cambridge

MAIN RESULTS FROM LMDz-INCA MODEL • Present emissions (2000) • Road traffic has the highest impact on ozone concentrations (up to 85% of the total impact of transport ), followed by ship and aircraft. • All together, the transport modes contribute to 4 to 9% of the ozone column in the whole Northern Hemisphere throughout the year. • Future emissions (2050) • According to A1 (B1) scenario, aviation (ship traffic) would become the major transport source of tropospheric ozone perturbation at global scale. • The contribution of all transport modes to the ozone column would: • A1: increase every where, reaching up to 13% in some areas such as Asia. • B1: decrease by 1% (Asia) to 2% (N. Hemis.) compared to 2000 QUANTIFY AC3 Workshop, August 2008, Cambridge
CURRENT WORK • Further analysis of the outputs • New simulations with 2000 anthropogenic emissions but with MESSy biogenic emissions (instead of ORCHIDEE) • PERSPECTIVES • 10-years simulation runs, using consistent Greenhouses Gaz Concentrations and Sea Surface Temperatures for the present and future will be done to better assess the impact of the transport modes on the tropospheric chemistry, including the climate feed-back. • = D3.3.2.3 deliverable QUANTIFY AC3 Workshop, August 2008, Cambridge
