Local and regional weather forecasts are an important component of the Department of Energy's (DOE) Savannah River Site (SRS) response capabilities in the event of hazardous accidental releases to the atmosphere. The fate of radiological or chemical releases can be determined by providing winds and turbulence input to atmospheric transport models. The Weather Information and Display (WIND) system consists of a network of computers and instruments that collect meteorological data from towers situated throughout the 800 square kilometer site, display updated results every 15 minutes, and supplies real-time data to a suite of personal computer (PC) based Gaussian dispersion models for assessing downwind hazards. It has been the primary consequence assessment tool for emergency response for many years. Several years ago, the SRS began using an advanced three-dimensional numerical model, the Regional Atmospheric Modeling System (RAMS) as a source of local forecast data for the basic WIND system models. The information RAMS provides to these dispersion models is spatially homogeneous. However, recently a more complete utilization of the spatially inhomogeneous RAMS forecasts has been realized by using a three-dimensional stochastic Lagrangian particle dispersion model (LPDM) to advect and disperse particles representing pollutant mass in the atmosphere. The purpose of this paper is to discuss the design and implementation of LPDM for use on a PC for real-time emergency response applications at the SRS.
