On the Leading Edge of Atmospheric Predictions   [open pdf - 1MB]

"In 2004, the Homeland Security Council named NARAC [National Atmospheric Release Advisory Center] as the interim provider of capabilities for the new Interagency Modeling and Atmospheric Assessment Center (IMAAC), which is led by the Department of Homeland Security (DHS). Under the U.S. National Response Plan, IMAAC coordinates dispersion modeling and disseminates hazard predictions for actual or potential incidents that require federal coordination. NARAC receives real-time observations and weather forecast data feeds from the National Weather Service's National Centers for Environmental Prediction, the U.S. Navy and Air Force, and many other sources around the world. The center collects more than one million meteorological observations per day. By combining this information with the center's databases of maps, terrain, land use, population, material properties, and release mechanisms, the operations staff can use NARAC computer models to generate predictions that focus on almost any area, whether the scale is urban, regional, or global. To provide integrated emergency response support, NARAC collaborates with more than 300 federal, state, and local agencies and emergency operations centers. The center's operational system responds to about 7,000 requests per year and has over 1,800 online users. An easy-to-use geographic information system (GIS) displays plume predictions and can export results to other GIS tools. Predictions can be requested and distributed with user-friendly Internetand Web-based software, and access is available via dial-up, satellite, Ethernet, and wireless networks."
