Impact of global changes on european pollution levels at the 2050 horizon

Abstract : The evolution of climate due to change in green house gas emissions and pointed by the IPCC community is liable to induce important impact on air quality. Both evolution of green house gas emissions due to policy and modification of meteorological parameters linked to climate change are likely to affect pollution levels, as well as the increase of global background ozone levels (Jacob et al., 1999). The aim of our work is to evaluate the impact of climate change (according to several scenari) as well as intra and extra European changes in emissions on European pollution levels in the mid term future (2050). Hence a long term simulation with the CHIMERE model is conducted, taking into account changes in emission levels according to RCP emission fields prepared in the IPCC framework. The climate is driven by CMIP3 global simulations from the IPSL climate model regionalised using the MM5 models. Investigations also focus on the identification of correlations between evolution of climate parameters and change in pollution levels.
