| Zusammenfassung |
| The Task Force on Hemispheric Transport of Air Pollution (TF HTAP) has initiated a variety
of model inter-comparisons to assess the ability of global atmospheric chemistry transport
models to simulate the long range transport of air pollution. We report here on the initial
results of Experiment Set 3 which compares the contributing models against data collected
during the international ITOP/INTEX/ICARTT campaigns over the North Atlantic during the
summer of 2004.
The basis of these comparisons is a cluster analysis approach which aims to objectively
define the characteristic airmasses found over the North Atlantic during this period. From
previous analysis of the observations we have identified six characteristic cluster / airmasses
types - biomass burning, low level outflow, upper level outflow, moist lower troposphere,
marine and upper troposphere. First, we compare the composition of these observationally
derived clusters to those found from each of the models. We then investigate the
relationships between the species within each cluster using a principal components
approach. |
