A Real-Time Atmospheric Dispersion Modeling System

This paper describes a new 3-D multi-scale atmospheric dispersion modeling system and its ongoing
evaluation. This system is being developed for both real-time operational applications and detailed
assessments of events involving atmospheric releases of hazardous material. It is part of a new, modernized Department of Energy (DOE) National Atmospheric Release Advisory Center (NARAC) emergency response computer system at Lawrence Livermore
National Laboratory. This system contains coupled meteorological data assimilation and dispersion models,
initial versions of which were described by Sugiyama and Chan (1998) and Leone et al. (1997). Section 2
describes the current versions of these models, emphasizing new features.
