  1. The characterization of pollution sources in eastern Asia using observations from the TRACE-P aircraft mission Ting S. Chen, D.J. Jacob, et al. Harvard University Atmospheric Chemistry Modeling Group • Objectives: • Identify CO2-CO-C2Cl4-CH3Cl-HCN and CH4-C2H6-CO relationships in Asian plumes sampled during TRACE-P • Relate these relationships to specific source signatures • Use these source signatures to test TRACE-P 3-D model simulations

  2. Chinese (Shanghai and Beijing) and Japanese urban plumes DC8-13: Yokota Local 1, 2001 March 21 CO2vs.CO Red points: Japanese plume - high CO2/CO, C2Cl4/CO - low HCN, CH3Cl Yellow/Blue points: Chinese plume - high HCN, CH3Cl: biofuel? C2Cl4 vs.CO HCNvs.CO CH3Cl vs.CO

  3. P3-B : Hong Kong Local 1, 2001 March 7 Biomass burning plume from SE Asia (in green) CO2 vs. CO HCN vs. CO C2Cl4 vs. CO Plume’s source region: Southeast Asia

  4. Preliminary Conclusions: • Biomass burning, China, Japan plumes have distinct CO2/CO signatures
