Abstract
During four seasonal periods in 1977, measurements of the rise and spread of the powerhouse plume of the Suncor plant in the tar sands area of Alberta, Canada were collected, using both ground-based photography and an instrumented aircraft. Supporting source and meteorological data were also monitored. In addition, some limited records of ground level SO2 concentrations during segments of the measurement period were obtained from low-level aircraft flights. Using this extensive data base, which encompasses a variety of atmospheric conditions, it has been possible to examine critically several facets of the usual approach to modelling plume rise and dispersion in the atmosphere. The aim of this paper is to present an overview of some of our results, without attempting to include all calculation details. For more detail, and for a complete description of the measurement program, the methods of data abstraction, and the models themselves, the reader is referred to Refs. 1, 2, and 3.
