Abstract
Models-3, a framework for air quality modeling, is scheduled for public release in June 1998. The framework will support statistical analysis and presently uses four SAS(R) modules (base, graph, AF and FSP) in the emissions processing. Statistics such as mean median, and percentiles can be plotted from Models-3 with IBM's Visualization Data Explorer. The statistical tool described in this paper is for policy planning for air quality issues related to annual or multi-year measures, rather than the most extreme events.
