Terrorism, including the threatened use of weapons of mass destruction against innocent civilian populations, has been adopted as a key instrument of asymmetric conflict between groups or nations of disparate political and military standing in the world. Given the complex and often ambiguous purposes motivating these acts, the anticipation, preparedness, prevention, and response to terrorism is exceedingly difficult, requiring a dedicated refocusing of our national security efforts.

As is evident from the figure, a comprehensive model takes into account the nature of the material released, local topography, and meteorological and atmospheric data; and from this information is derived some form of risk parameters. Current available modeling systems range from the relatively simple to the highly complex (for example, a sophisticated model may contain its own meteorological prediction component and interactive atmospheric chemistry)

il Much can be done with existing resources to strengthen observational and modelng capabilities for tracking hazardous releases, such as better use of existing local observational networks and better exploitation of existing models. However, additional resources likely will be required by many communities for the development and implementation of improved observing systems and higher-resolution models.
