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.

chloride, toluene, diisocyanate, sodium
hydroxide, hexane, and phenol.

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
13Workshop Goal
Improve agency coordination in the development
and operational use of dispersion models.
14Workshop 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
15Session 1
Tuesday morning
- User Requirements for Dispersion Modeling
- Agencies current requirements
- How current requirements are being met
- New/unmet requirements
16Session 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
17Session 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
18Session 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
19Session 5
Thursday morning
- Summary and Wrap-Up
- Panel and breakout chairs report results and
recommendations - Next steps/follow-on actions
- Closing remarks
