Construction of Hg Emissions Inventory Using Bottoms-Up and Observed Hg/SO2 Ratios

Summary

• Aerosol outflow is complex, characterizing it requires 4-dimensional measurements.

• Impacts on chemistry and radiation appear to be important.

• Closer integration of emissions, models and measurements is necessary to better quantify our understanding of Asian aerosols.
