| Zusammenfassung |
| We present and discuss a new dataset of gridded emissions covering the
historical period (1850–2000) in decadal increments at a horizontal
resolution of 0.5° in latitude and longitude. The primary purpose of
this inventory is to provide consistent gridded emissions of reactive gases
and aerosols for use in chemistry model simulations needed by climate models
for the Climate Model Intercomparison Program #5 (CMIP5) in support of
the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment report
(AR5). Our best estimate for the year 2000 inventory represents a
combination of existing regional and global inventories to capture the best
information available at this point; 40 regions and 12 sectors are used to
combine the various sources. The historical reconstruction of each emitted
compound, for each region and sector, is then forced to agree with our 2000
estimate, ensuring continuity between past and 2000 emissions. Simulations
from two chemistry-climate models are used to test the ability of the
emission dataset described here to capture long-term changes in atmospheric
ozone, carbon monoxide and aerosol distributions. The simulated
long-term
change in the Northern mid-latitudes surface and mid-troposphere ozone is
not quite as rapid as observed. However, stations outside this latitude band
show much better agreement in both present-day and long-term trend. The
model simulations indicate that the concentration of carbon monoxide is
underestimated at the Mace Head station; however, the long-term trend over
the limited observational period seems to be reasonably well captured. The
simulated sulfate and black carbon deposition over Greenland is in very good
agreement with the ice-core observations spanning the simulation period.
Finally, aerosol optical depth and additional aerosol diagnostics are shown
to be in good agreement with previously published estimates and
observations. |
