Langner et al. (2012a) found that climate change lead to
small decreases
of [O3] in northern Europe
and small increases in southern Europe.
When running
the future
period
with air pollutant emissions from the
RCP4.5 scenario valid for year 2050, a large decrease of [O3] is observed
throughout Europe.
Although both the climate and emission scenarios
are uncertain, this demonstrates the much larger effect of plausible
emission changes than calculated climate change over the coming decades.
The modelled future evolution of daily maximum [O3] continues
in line with the observed historical decrease of maximum [O3] during
summer daytime, see Tables 2 and 3. Uncertainties in CTM responses
to climate change and changes in emissions are, for example, discussed
in Langner et al. (2012b) andWatson et al. (2016); both studies provide
multi-model assessments of future ozone.
