Abstract

Measured SO2 concentrations collected during the Regional Air Pollution Study (RAPS) in St. Louis have been used in various RAM evaluation studies (Turner and Irwin, 1983 and 1985). Turner and Irwin (1985) indicated that significant bias existed in the model when both measurements and model results were examined according to stability. The model predicted highest concentrations under stable conditions, whereas measurements revealed the highest concentrations occurred over a variety of conditions ranging from moderately unstable to moderately stable. Although proof was unobtainable, a primary conjecture was that the inclusion of all but the largest 196 point sources in the emission inventory as area sources contributed to the occurrence of the calculated maxima with stable conditions.
