Urban Dispersion for the 21st Century
The threat of terrorist attack using gaseous or biological agents has changed the focus of urban dispersion research programs. No longer are the studies being conducted solely in intensive programs to explore specific aspects identified by slowly evolving numerical simulations. Instead, there is an emerging parallel thrust to optimize the use of existing data and to provide forecasts based on heavily on data assimilation. In this context, there is a basic rule that appears to be emerging: to maximize the accuracy of predictions, minimize the reach beyond reliable observations. Within an urban canopy (i.e. in the street canyons) the complexity of transport through the air is such that an accurate prediction of concentrations at any specific place and time is unlikely, regardless of the proximity of accurate meteorological data. Some options are reviewed, as are currently being tested in Washington D.C. and New York City.
