Abstract:

Six diagnostic atmospheric dispersion modeling groups NUATMOS CITPUFF, CALMETCALPUFF PGEMS, WOCSSMACHWINDAdaptive plume, and LINCOM RIMPUFFHEAVYPUFF are evaluated for use in specifying toxic hazard corridors for rocket propellent and oxidizer cold spills at Vandenberg AFB. Other models are also considered briefly. Physical assumptions, speed, cost, availability, ease of use, compatibility with existing risk assessment systems, validation, data requirements, and Vandenberg suitability are discussed. Underlying physical basis and modeling technique are emphasized. Dispersion models consist of separable windflow and dispersion sub-models. A MACHWINDLINCOM windflow tandem with ADPIC, RIMPUFF, or CALPUFF diffusion may provide the most robust diagnostic modeling suite. A costbenefit analysis of computer hardware and modeling accuracy is given....
