Abstract:

In a chemicalbiological attack or accident, installation commanders, Emergency Operations Centers, and first responders need immediate knowledge of local wind and other meteorological conditions at the fine scales appropriate to the emergency. Therefore, the U.S. Army Research Laboratory ARL, Battlefield Environment Division has proposed developing a Local-Rapid Evaluation of Atmospheric Conditions L-REAC System. The objective networking design for the L-REAC system will use real-time networked meteorological sensors placed at optimum locations. These data will be input in near real-time to the fastest running version available of the ARL Three Dimensional Wind Field 3DWF model or similar urban wind field model. Continuous running updates on a server will produce a detailed picture of wind flow over the local installation available 247 to all forms of browser-based access such as mobile blackberry browser. In 2006, the ARL presented data at an International Test and Evaluation Association conference which verified millimeter-scaled airflow patterns observed in the 1994 Snyder and Lawson National Oceanic and Atmospheric Administration NOAAEnvironmental Protection Agency EPA Wind Tunnel study with tens-of-meter-scaled measurements sampled around a full-sized building. In 2007, this ARL urban airflow research pursued an even greater spatially and temporarily detailed investigation of the urban environment around individual buildings. From this 2007 field study, the L-REAC concept was generated. This paper will present the L-REAC system and an overview of the experimental test and evaluation of features for the model to simulate urban wind flow.
