Integration of Atmospheric Contaminant Plume Calculations Into ArcView Track: Homeland Security Author(s): Larry Koffman The Savannah River Technology Center (SRTC) plays a key role in emergency response scenarios in which there may be a release of atmospheric chemical or radiological contamination at the DOE's Savannah River Site. Meteorologists at SRTC use the Puff/Plume code, which is tied to real-time wind data, to predict the direction and spread of the atmospheric plume. An ArcView extension was written to integrate the results of this calculation into ArcView for overlay with other geographic data. The meteorologists use the more sophisticated Lagrangian Particle Dispersion Model (LPDM) to predict particle dispersion and deposition. nother ArcView extension was written to import the resulting matrix of point data and convert the data to a grid using the ArcView Spatial Analyst extension. Contours of interest are generated from the grid. Direct integration of such modeling results into ArcView improves the capability for decision making during an emergency.
