To this aim simulations with two different configurations of the GEOS-CHEM chemical transport model are conducted a) driven from the GISS III general circulation model (4ox 5o) for a present (1999–2001) and a future (2049–2051) period and b) driven by assimilated meteorological data (GEOS, 0.5o x 0.667o) for the year 2005. Results indicate highest increases between the future and the reference period in the north west and the south west Europe for both the average mean (~ 5 ppb) and average daily maximum ozone concentrations (~ 10 ppb) whereas the highest decreases (~ 4-6 ppb) are shown in the south East Europe for the same statistical targets. Moreover, these results are of the same sign to the results of the global climate-chemical modelling system in the North-west and the South-east Europe. Nevertheless changes in the GISS/GEOS-CHEM between the future and the present climate are in the range of ± 2 ppb and ± 3 ppb for the average mean and the average daily maximum ozone concentrations respectively. 6 pp. LOMv1.0 creator LOMv1.0 Scientific Coordinator LOMv1.0 Project Executing Organisation 2014 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text Climate changes Ozone concentrations Europe Future emissions 754105 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/3031/2/3031_1.45_%ce%94%ce%97%ce%9c_30_1_14.pdf URI http://hdl.handle.net/10795/3031 LOMv1.0creator 2016-05-05T12:47:01Z LOMv1.0validator 2016-05-05T12:47:01Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
