To provide a full assessment, simulations with the global chemical transport model GEOS-CHEM driven by the NASA Goddard Institute for Space Studies general circulation model (NASA/GISS GCM) are conducted. To isolate the effects from changes in climate and anthropogenic emissions four types of simulations are performed: (1) present-day climate and emissions (2) future climate following the IPCC Special Report on Emission Scenarios (SRES) A1B scenario and present-day anthropogenic emissions of ozone precursors (3) present-day climate and future emissions and (4) future climate and future emissions. Results indicate that climate change impact on its own leads to an increase of less than 3 ppb in western and central Europe whereas decreases are evident for the rest of the areas with the highest (about 2.5 ppb) in southeastern Europe (Italy, Greece). Increases are attributed to the increases of isoprene biogenic emissions due to increasing temperatures whereas decreases are associated with the increase of water vapor over sea which tends to decrease the lifetime of ozone as well as the increased wind speeds in the 2050 climate. When future emissions are implemented in the future climate simulations, the greatest increases are seen in the southwest and southeast Mediterranean (about 16 ppb) due to the increased isoprene biogenic emissions under higher levels of NOx in the model. Decreases up to 2 ppb of ozone are shown for France, Switzerland, Northern Italy and northern Europe. 13 pp. LOMv1.0 creator LOMv1.0 publisher LOMv1.0 Scientific Coordinator LOMv1.0 Project Executing Organisation 2013-05-25 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text Climate change Ozone Europe Future emissions 5304855 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/3030/3/3030_1.45_%ce%94%ce%97%ce%9c_25_5_13.pdf URI http://hdl.handle.net/10795/3030 LOMv1.0creator 2016-05-05T12:06:17Z LOMv1.0validator 2016-05-05T12:06:17Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
