 abstract = {[1] An integrated global model of climate,
tropospheric gas phase chemistry, and aerosols has been used to
investigate the sensitivity of global ozone and fine particulate
matter concentrations to climate change. Two simulations
corresponding to present (1990s) and future ( 2050s) climates have
been performed and compared. A future climate has been imposed
using ocean boundary conditions corresponding to the
Intergovernmental Panel on Climate Change SRES A2 scenario for the
2050s decade, resulting in an increase in the global annual average
values of the surface air temperature by 1.7 degrees C, the lower
tropospheric specific humidity by 0.9 g H2O/kg air, and the
precipitation by 0.15 mm d(-1). Present-day anthropogenic emissions
have been used in both simulations while climate-sensitive natural
emissions were allowed to vary with the simulated climate. The
tropospheric ozone burden in the future climate run decreased by
5%, and its lifetime decreased from 27.8 to 25.3 days. The
tropospheric ozone change is driven primarily by increased ozone
loss rates through ozone photolysis in the presence of water vapor,
which on a global scale, more than compensate for the increased
ozone chemical production associated with increased temperatures.
At the model surface layer, over remote regions, ozone mixing
ratios decreased by 1-3 ppbv, while polluted regions showed a
relatively smaller decrease of 0-1 ppbv and increased by 1-5 ppbv
in some cases. The global burdens and lifetimes of fine particulate
matter species in the future climate run decreased by 2 to 18%
because of increased wet deposition loss rates associated with
increased precipitation. At the model surface layer, there are
regions of decreases and increases in the concentrations of fine
particulate matter species. The increased surface layer
concentrations of some fine particulate matter species is primarily
driven by lower regional-scale precipitation and increased
secondary production, where applicable. The robustness of the
predicted regional-scale changes for fine particulate matter
species is strongly dependent upon the predicted regional-scale
precipitation changes.
