Predicting Direction of Toxic Releases

Protecting the nation from deliberate acts of terrorism (such as anthrax) or from a toxic release caused by a natural disaster or an industrial or transportation accident.
Challenge: 

Protecting the nation from deliberate acts of terrorism (such as anthrax) or from a toxic release caused by a natural disaster or an industrial or transportation accident. 

Solution: 

Homeland Security Technologies – NCAR has joined with other federal agencies to develop new technologies that make our communities less vulnerable to biological and chemical attack. Our Source-Term Estimation method research applies a variety of algorithms to the latest weather prediction and transport-and-diffusion models to help emergency managers reconstruct a release, and to develop a better situational awareness of how a population was exposed.

Benefits: 

This technology was successfully integrated into the US Department of Defense (DoD) emergency response modeling systems—HPAC (Hazard Prediction and Assessment Capability) and JEM (Joint Effects Model) in 2012.
