The three-dimensional distribution and transport of air pollutants has been studied. The export of ozone or its precursors from the Los Angeles and Denver metropolitan areas was documented. Analysis of the July 25, 1973 smog episode in the Los Angeles Air Basin indicated that ozone was being exported from the western, heavily urbanized, portion of the basin at rates exceeding 100 metric tons per hour during much of the afternoon. High ozone concentrations confined to the surface mixing layer in the relatively remote mountain and desert areas east and northeast of Los Angeles were documented and traced back to their probable source in the Los Angeles Air Basin. Standard diffusion estimates based on one episode indicated that, over flat terrain in the absence of scavenging mechanisms, an ozone source the size of the Los Angeles metropolitan area could cause ozone concentrations to exceed the Federal standard of 0.08 ppm at locations as far away as 260 km. From the data studied, it was concluded that urban sources can have a substantial effect on ozone concentrations in downwind areas, and that this effect can carry over more than one day.
