Fraction of total modeled deposition attributed to direct anthropogenic emissions from the USA and China.
Results are shown for Lake Erie and Lake Superior, to illustrate differences in the modeled source-attribution patterns for 2005. Each panel shows the results for a particular series of model configurations. The assumed oxidation scaling for each series (20%, 33%, or 10%) is shown, and within each series, the data are plotted as a function of the assumed amount of plume reduction of emitted Hg(II).
