Effect of climate change on the future chemical composition of the atmosphere
The scope of this thesis is to investigate the potential impact of future
climate change on ozone and secondary inorganic particulate matter
concentrations in Europe. To this aim a statistical model to examine the
potential impact of increasing future temperatures due to climate change on
ozone exceedances is developed. The statistical model is based on the fact that
the total derivative of ozone with temperature reflects the sum of the partial
derivatives of ozone with temperature-dependent physical and chemical
processes. The historical ozone-temperature relationship is examined and then
combined with future temperature projections from 3 state-of-the-art regional
climate models to provide estimates of future ozone exceedance days under the
assumption that this relationship will retain its main characteristics. In
addition simulations with the global chemical transport model GEOS-CHEM driven
by the NASA Goddard Institute for Space Studies general circulation model
(NASA/GISS GCM) are conducted to examine the effects from changes in climate
and emissions on future ozone and secondary inorganic particulate matter
concentrations. Finally, the results of the statistical approach are examined
against those simulated by the GISS/GEOS-CHEM dynamical modelling system.
