  5. Why are we here? CNN/KATC-TV photo CNN/KATC-TV photo Eunice, LA. (Reuters) - Hazardous-chemical specialists plan to put out fires still burning in two tank cars of plastics Tuesday and then begin moving some of 30 freight cars that derailed Saturday in southwest Louisiana, forcing 2,500 people from their homes. Residents were ordered to flee from a 2-1/2-mile radius around the site within minutes.... Dense smoke poured from the scene for almost 24 hours, police said. ... dichloropropane, acrylic acid, methyl chloride, toluene, diisocyanate, sodium hydroxide, hexane, and phenol.

  10. Summary • Potential for ATD modeling to touch every aspect of our lives - effects demonstrated daily • Growing concerns over chemical and biological terrorism demand attention • This workshop will let us assess where we are and set a direction for the future

  11. Opening Remarks Workshop on Multiscale Atmospheric Dispersion Modeling within the Federal Community Dr. Darryl Randerson Chief, Special Operations and Research Division, Air Resources Laboratory, NOAA Chairman, Joint Action Group for Atmospheric Transport and Diffusion June 6, 2000

  12. Workshop Goal Improve agency coordination in the development and operational use of dispersion models.

  13. Workshop Objectives • State current modeling requirements and capabilities • Specify new requirements/unmet needs • Describe existing methods for validation, verification, and approval of current models and future needs • Describe a process for establishing model subsets for specific applications • Find solutions to agency-identified technical barriers • Identify opportunities for leveraging model development and model validation, verification, and approval

  14. Session 1 Tuesday morning • User Requirements for Dispersion Modeling • Agencies’ current requirements • How current requirements are being met • New/unmet requirements

  15. Session 2 Tuesday afternoon • Agency Dispersion Modeling Capabilities • What models are currently used for operations? • How does modeling capability meet agency requirements? • How are models evaluated? • Who are the users; what products are distributed; what are training requirements? • Research/development for unmet user needs

  16. Session 3 Wednesday morning • Technical Barriers to Dispersion Modeling • Turbulence and the stable boundary layer • Air-surface exchange • Probabilistic modeling • Mesoscale and surface layer transport • Neighborhood-scale processes

  17. Session 4 Wednesday afternoon • Model Validation, Verification, and Approval; Model Subsets • Develop a framework for the validation, verification, and approval of dispersion models • Identify “subsets” of scientifically and technically sound models suitable for different operational scenarios

  18. Session 5 Thursday morning • Summary and Wrap-Up • Panel and breakout chairs report results and recommendations • Next steps/follow-on actions • Closing remarks

  19. Let’s get started... Session 1: User Requirements for Dispersion Modeling Session Chair: Rickey Petty, DOE Rapporteur: Roger Stocker, DOD/USN
