Results of encounters with urban plumes during field studies in California, Missouri, and Tennessee are reviewed which indicate that no areas within a few hundred kilometers of large urban areas are not influenced by aerosols from the urban areas at least part of the time. Aircraft measurements of aerosol size distribution and growth in the St. Louis urban plume are analyzed. It is found that nuclei formation rates ranged up to several hundred per cu cm/hr and that nuclei and ozone formation rates correlated well with ground-level UV intensity. The analysis also indicates aerosol volume formation rates as high as 6.7 cu microns per cu cm/hr that appear to correlate well with the UV radiation. A simple aerosol growth model based on the experimental results shows that the total weight of secondary aerosol formed in the plume during one irradiation cycle was 1000 metric tons/day.
