Joint Urban 2003 street canyon experiment

As part of the DOE-DTRA Joint URBAN 2003 field experiment in Oklahoma City, a multi-group team instrumented a downtown street canyon with a high density of wind sensor instrumentation. The goal was to garner flow field information in order to better understand the transport and dispersion of tracers released in the street canyon. In this paper, we briefly review prior field and laboratory experiments on street canyon flow, describe our experimental set-up and measurement apparatus, present some preliminary analyses of the measurements, and discuss their significance in relation to current understanding. Eventually this data set will be used to evaluate the next generation of urban dispersion models (e.g., Cox et al., 2000; DeCroix, 2002; Hall et al., 2000; Williams et al., 2002).
