| Zusammenfassung |
| The impact of climate change and changes in ozone precursor emission on
summer surface ozone in Europe was studied using a regional CTM over the
period 1990 to 2100. Two different climate simulations under the SRES A1B
scenario together with ozone precursor emission changes from the RCP4.5
scenario were used as model input. In southern Europe regional climate
change leads to increasing surface ozone concentrations during
April–September, but projected emission reductions in Europe have a stronger
effect, resulting in net reductions of surface ozone concentrations. In
northern Europe regional climate change decreases surface O3 and
reduced European emissions acts to further strengthen this trend also when
including increasing hemispheric background concentrations. The European
O3 precursor emission reductions in RCP4.5 are substantial and it
remains to be seen if these reductions can be achieved. There is substantial
decadal variability in the simulations forced by climate variability which
is important to consider when looking at changes in surface O3
concentrations, especially until the first half of the 21st century. In
order to account for changes in background O3 future regional model
studies should couple global (hemispheric) and regional CTMs forced by a
consistent set of meteorological and precursor emission data. |
