Introduction The transport and dispersion of pollutants over an urban area is an important problem due to the concentration of pollutant sources as well as population near cities. Most past tracer studies of dispersion near urban areas have released tracer material from within rather than outside the urban complex; many have used non-conservative fluorescent particles; and all have been conducted for a very limited period of time. The pollutants of interest, such as sulfur dioxide, normally originate at so many known and unknown sources that interpretation with regard to transport of individual plumes becomes virtually impossible. Furthermore, most tracer experiments were constrained to limited meteorological conditions because of a fixed orientation between release and sampling locations. Our proposed experiment overcomes all of the above shortcomings.
