Abstract

The U.S. Department of Homeland Security (DHS), with support from the Defense Threat Reduction Agency (DTRA), Environmental Protection Agency (EPA) and the Department of Energy is sponsoring a multi-year investigation to better understand how contaminants behave in complex inner city urban canyons. This effort will involve a broad team of collaborators from several U.S. National Laboratories, academic institutions and other government agencies. A series of tracer gas field studies in New York City will be conducted that will track meteorological conditions and measure the flow of tracer gases as a simulant for toxic contaminants. The data will then be used to evaluate and improve state-of-the-art mathematical models to predict atmospheric flow. These models will provide assistance to first responders and emergency management personnel to help in making difficult decisions to protect human health and safety in the event of an accidental or intentional (i.e., terrorist) toxic release.
城市分散规划:更好地理解城市峡谷环境中的污染物运输
在国防威胁减少局(DTRA)、环境保护署(EPA)和能源部的支持下,美国国土安全部(DHS)正在发起一项为期多年的调查,以更好地了解污染物在复杂的内城城市峡谷中的行为。这项工作将涉及来自几个美国国家实验室、学术机构和其他政府机构的广泛合作团队。将在纽约市进行一系列示踪气体实地研究,跟踪气象条件并测量作为有毒污染物模拟物的示踪气体的流量。这些数据将用于评估和改进最先进的数学模型,以预测大气流动。这些模型将为第一反应人员和应急管理人员提供援助,帮助他们在发生意外或故意(即恐怖分子)释放有毒物质的情况下作出艰难的决定,以保护人类健康和安全。
