• Construction of a worldwide fossil fuel BC and OC emissions inventory from 1950 to 1997, and projections : - mobile sources- stationnary sources- biomass burning ...

• Global modelling of the transport, wet and dry deposition, and of radiative impact with the TM3 model

Future work : zooming on Europe

UNECE-CLRTAP and EMEP Task Force on Integrated Assessment Modelling27th session, Oslo, 13-15 May 2002

• Spatially refined, and improved BC and OC inventories with fuel consumption data from the Convention.

• Include all relevant aerosols in the radiative transfer model, so as to give a complete picture of the radiative effect of particulate matter for Europe.

• Simulate different control options for PM and their impact on radiative forcings and visibility reduction.
