This document presents a review (ca. April 1977) of available air quality simulation models that are appropriate to long-range transport (e.g., 100-1000 km) of atmospheric pollutants. This review has been prepared as part of an effort to select, modify and apply long-range atmospheric transport and diffusion models suitable to the simulation of air quality impact associated with emissions from new energy resource development (power generation, coal gasification, oil shale processing) in the Four Corners Area of the Western United States. In this effort, primary emphasis has been placed upon the review of models that are already operational, and that are, in principle, currently available for use and adaptation outside the originating organization. A number of additional constraints were used to select models for review. These included the relative ease and costs of modification for use in the Four Corners Area, the computer implementation restrictions, the computational, and data and technical resources required for program utilization, the flexibility for multiple-scenario exercise to address both short-term and long-term ambient air quality issues. To facilitate the description and intercomparison of the various models, a 'model characteristics' outline form of presentation has been used.
