5203 |a"The study describes the change in meteorological conditions and associated air quality both at ground level and aloft from just prior to sunrise, at which time a stable atmosphere and low ground level pollutant concentrations existed, to the early afternoon of the same day when solar heating resulted in the development of a classic inversion fumigation condition for a period of a few hours. Profiles of temperatures and winds were obtained using specifically designed battery operated radiosonde receivers with slow rise balloons. The spatial distribution of sulphur dioxide concentrations was obtained utilising two automobiles and a helicopter each instrumented with a continuous rapid response analyser. The plume was measured to rise to a level at which an intensification of an inversion was noted. Average ground level concentrations as high as 0.90 ppm were measured at a distance of 6 km from the source during the inversion fumigation. The measured concentrations compared well with predictions using established formulae"--Abstract, p. [1].
