Construction of Hg Emissions Inventory Using Bottoms-Up and Observed Hg/SO2 Ratios “Observed” Hg(Kg)
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.
