In this study a methodology is developed that applies the ozone concentration change signal from a global climate-chemical modeling system with a coarse horizontal resolution to a finer resolution. 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.
