Atmospheric dispersion modeling and meteorological monitoring in support of emergency planning and response for the US Army's Chemical Stockpile Disposal Program

Abstract

This technical memorandum examines the role of atmospheric dispersion modeling and meteorological monitoring in support of emergency planning and response for the US Army's Chemical Stockpile Disposal Program (CSDP). Air dispersion modeling and meteorological monitoring are expected to form key components in integrated accident assessment and warning systems at each of the eight CSDP installations. This report assesses the capabilities of operating state-of-the-art systems in order to establish a baseline for developing the requirements of the CSDP systems. A general tutorial on the types of atmospheric dispersion models currently available is provided, and the criteria for selection of emergency response models are developed. The requirements for meteorological monitoring are also described. In addition, the basic limitations of modeling and monitoring are discussed, and the importance of model verification is emphasized. Staffing requirements to operate an integrated modeling and monitoring system are characterized. The current state of modeling, monitoring, and staffing levels in support of emergency response at the eight US Army chemical stockpile depots involved in the CSDP is examined. Specific requirements appropriate to emergency planning and response at each of the eight sites are described. Recommendations are made for both the integrated system and the individual components of air dispersion modeling and meteorological monitoring. Finally, future work required to prepare for emergency response is discussed. 22 refs., 4 figs., 3 tabs.
