Interannual variability in long-range transport of pollution

We are using the GEOS-Chem model to study the influence of long-range transport of pollution from the midlatitude northern hemisphere to the remote atmosphere. We are interested in characterizing the pathways for transport of this pollution into the southern hemisphere and the interannual variability of the transport pathways. A particular focus is in on quantifying the impact of Asian pollution on CO and O3 in the remote atmosphere, and understanding how changes in climate over the last 2-3 decades have influenced the export of Asian pollution to the global atmosphere.
