      abstract     = {In this study, we investigated the effect of numerous
                      regulations enforced since 1985 to improve air quality on
                      ozone in Europe with the focus on Switzerland, using the
                      Comprehensive Air Quality Model with Extensions (CAMx) for a
                      specific summer period. Several emission scenarios for the
                      year 2010 were also considered. The model results suggest
                      that the emission reductions of ozone precursors should have
                      been effective to reduce ozone production between 1985 and
                      2000 in northern Switzerland. However, observations do not
                      indicate any significant change in surface ozone levels
                      since early 1990s, except in the region of Zurich where
                      there is a small negative trend. On the other hand, the
                      model predictions match very well the spatial variability of
                      the trends but the calculated trends are around 0.5 ppb
                      year(-1) lower than those observed. This difference is
                      similar to the background ozone increase as suggested by the
                      long-term observations at the high Alpine station
                      Jungfraujoch. These results support the hypothesis that the
                      decrease in local ozone production due to emission
                      reductions might have been partly or completely compensated
                      by the simultaneous increase in the background ozone. In
                      2010, a strict application of the Gothenburg Protocol in
                      Europe would lead to a decrease in peak ozone concentrations
                      by about $5\%$ in Switzerland under the meteorological
                      conditions applied. our calculations also indicated that
                      emission controls only in Switzerland would not be very
                      effective to improve the air quality in the future. The
                      further development of the background ozone will in any case
                      be very important for the tropospheric ozone levels. (C)
