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.
