Organization of Course INTRODUCTION 1. Course overview 2. Air Toxics overview 3. HYSPLIT overview Overall Project Issues & Examples 9. Emissions Inventories 10. Source-Receptor Post. Processing 11. Source-Attribution for Deposition HYSPLIT Theory and Practice 12. Model Evaluation 4. Meteorology 13. Model Intercomparison 5. Back Trajectories 14. Collaboration Possibilities 6. Concentrations / Deposition 7. HYSPLIT-SV for semivolatiles (e. g, PCDD/F) 8. HYSPLIT-HG for mercury

There are Many Opportunities for Collaboration q HYSPLIT can be used for fate/transport and trajectory modeling q Sharing of Data o Emissions Inventories o Meteorological Data o Monitoring Data for Model Evaluation q There is strong interest at NOAA and elsewhere in the Gulf of Mexico …an area of joint concern q The NOAA Air Resources Lab has a mercury measurement site on the Northern Gulf of Mexico Coast… to interpret measurements there and to evaluate our models against these measurements, we are interested in atmospheric mercury emissions, fate, and transport in Mexico
