Abstract |
VISTTA (Visibility Impairment due to Sulfur Transport and Transformation in the Atmosphere) is a program sponsored by the U.S. Environmental Protection Agency to study the effect of anthropogenic emissions on atmospheric visibility. During the winter and summer of 1981, plume measurement programs were conducted in the vicinity of the Kincaid power plant near Springfield, Illinois; the Labadie power plant near St. Louis, Missouri; the La Cygne power plant near Kansas City, Missouri; the Magma copper smelter near San Manuel, Arizona; the Phelps-Dodge copper smelter near Douglas, Arizona. This report presents a data base collected during the 1981 VISTTA field program that can be used for plume visibility model evaluation. Specific data from nine sight paths through the Kincaid power plant plume on 20, 24, and 25 February 1981, the Labadie power plant plume on 24 and 29 August 1981, and the San Manuel smelter on 8 September 1981. |
