English Abstract This project focuses on the interactions of climate
change, acidification, eutrophication, tropospheric ozone, stratospheric
ozone and some other air pollutants (like soot). The following research
questions have been addressed: (i) Which interactions exist between
acidification, tropospheric ozone formation, climate change and
stratospheric ozone depletion? (ii) How can these interactions be analysed
either by means of existing models, or by combining parts of these models,
or by new model structures focusing on these interactions? (iii) Which data
is required at the appropriate spatial and temporal scales for these themes,
and how can these different scales be integrated? (iv) Which information is
already available in existing emissions inventories and existing models?
For a combined analysis of climate changes and transboundary air pollution,
it is proposed to first decouple climate change calculations from air
pollution calculations in an analysis at the global level, in order to
determine emission reduction targets for greenhouse gases for Europe. For
this purpose, calculations could first be performed with MERGE or ECHAM for
climate change in order to establish emission targets for Europe. Next, the
optimized emission levels (and of course also the calculated concentration
fields and changed meteorological conditions) should be used as one of the
restrictions in an optimisation analysis at the European level, using a
newly developed model, based on elements of the RAINS model and the more
detailed LOTOS system for transboundary air pollution. Subsequently with
this model optimisation runs should be performed to calculate optimal
emission reduction strategies for transboundary air pollution and emissions
of greenhouse gases, considering the interactions as identified in this
study.
