Short Range Dispersion Experiments in an Urban Area
We present results from a series of nine tracer experiments studying urban dispersion at distances under 600 m from a ground level point source in Worcester, Massachusetts. Gaussian forms provide a good fit to the lateral concentration distributions. The measured parameters were compared with models based on stability classification and wind direction fluctuations and to other urban and rural experiments. The comparison showed general consistencies with urban models and data, with some evidence for short range enhancement of the plume. The growth of the cross wind dispersion coefficient (σy) and of the standard deviation of wind direction fluctuation (σθ) with sampling time were investigated and showed considerably slower growth than is commonly assumed. © 1983.
