The Multistate Atmospheric Power Production Pollution Study (MAP3S), begun in the mid-1970's under Department of Energy sponsorship and continued with support from the Environmental Protection Agency, was designed to investigate the long-range transport and deposition of sulfur pollutants from utility coal combustion, but the scope has been broadened to acidic depositions from all sources. The bulk of the numerical model research has been conducted by groups at three of the national laboratories; Argonne (ANL), Brookhaven (BNL), and Battelle Pacific Northwest (PNL). This report addresses an intercomparison with data of the Atmospheric Impact of Residual Sulfur OXide (AIRSOX) model of BNL, the Regional Air Pollutant Transport (RAPT) model of PNL, and the Advanced Statistical Trajectory Regional Air Pollution (ASTRAP) model of ANL. AIRSOX and RAPT model individual trajectories, while ASTRAP models trajectory ensembles. Parameterizations are summarized. The models are structured so that they apply to any pollution in which chemical transformation can be approximated as linear first-order; in the intercomparison, however, only sulfur oxides were examined.
