The laboratory experiments on street canyon flow, the measurement apparatus and preliminary analysis of the measurements were discussed. The DOE-DTRA Joint URBAN 2003 field experiment was held in Oklahoma City in July 2003, with an aim to provide information useful for testing and evaluation of the next generation urban transport and dispersion models. On Park Avenue, within one block section of a street canyon, several wind sensors were placed at street level, on towers and at roof level. The results show 180 wind direction shifts on the OU 15M towers located at canyon midpoint, a vortex in the horizontal plane near street level at the eastern end of the street canyon and differences in turbulence levels between day and night.
