  1. Regional-Scale Modeling and Emissions Analyses in Support of Ace-Asia CFORS Team: Kyushu/Argonne/Iowa G. Carmichael, I. Uno, D. Streets, Y. Tang, J. Woo, S. Guttikunda, N. Thongboonchoo, S. Sataka, G. Kurata, J. Yienger, M. Uematsu, N. Sugimoto, B. Huebert, T. Clarke, T. Bates, T. Quinn, R. Weber, H. Friedli, T. Chen, B. Blomquist

  2. BC at surface BC C-130 #11 April 19th

  3. Asian Outflow: Complex Mixture of Dust, Bio, and Fossil Components April 12 April 9 Data: Sugimoto, et al. Poster: A11A0060 Sataka et al.

  4. PDF main parts CFORS Forecasts Sometimes Under-predicted Elevated Dust Layers Tokyo ??? TUMM Lidar profile for April 10, 2001 TOMS AI April 10 CFORS Dust Elevated dust layer Poster: Mon. A12B-0151 Uno et al. Beijing Lidar experience = 0.1 / km -> 178mg/m3

  5. Log10(Dust) Ron Brownobserved high AOD in Japan Sea Takla makan Lidar Ext. Of Ron Brown = 0.2/km Gobi This may be Miyakejima sulfate AOD Observed Al and model dust Plate 2 Poster: Mon. A11A-0049 Bates et al.

  6. BC SO4

  7. Characterization of Emissions usingBack Trajectory Analysis -- ACE-Asia Color code indicates plume age in days from that city No. of Points 1457 out of 2994

  8. What Does This Analysis Tell Us About BC Emissions? CO vs. BC Obs. Poster: Mon. A11A-0062 N. Thong.

  9. But Magnitude Is Still an Issue: Are Domestic Sector Emissions Underestimated ??

  10. How is Photochemistry Impacted By These Aerosols? 1) Photolysis Impacts

  11. How is Photochemistry Impacted By These Aerosols? 2) Heterogeneous Rxns:Direct Ozone Loss? W/O Het. Rxn

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

  13. 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.
