URBAN 2000 SF_6 ATMOSPHERIC TRACER RESULTS FROM THE SUBURBAN EXPERIMENT DOMAIN

摘要

The threat of a terrorist releasing a toxic gas in an urban environment has taken on a new focus in recent months. The effort to model the effects of such a prospect has also been enhanced. It is clear that model results must be interpreted in light of the model's ability to accurately predict the real world. Model accuracy is determined through the model validation process, which relies primarily on data acquired from field trials such as atmospheric tracer tests. URBAN 2000, an atmospheric tracer study, was conducted to establish a database that extends from the single-building scale, to the multi-building scale, to the urban scale, and ultimately to the suburban scale (6 km). The project has been described in detail by Allwine et al. (2002). The month-long field study was funded primarily by the by the U.S. Department of Energy's (DOE's) Chemical and Biological National Security Program. It involved researchers from several national laboratories, universities, and government agencies including the Field Research Division (FRD), making for a rather large experiment. Hence, this paper will focus on the results obtained from the six real-time mobile SF_6 analyzers that were used in six intensive observation periods (lOPs).
