Models-3 is an extensible environmental modeling system designed to meet the research and regulatory needs of the EPA and other users into the twenty-first century. As such, it must deal with a number of problems. These problems include (1) the scientific correctness, flexibility, and usability required, (2) automating much of the complexity of planning, scheduling, and management of the computations associated with environmental studies and the massive volumes of data these studies produce, and (3) the software engineering issues associated with developing a modular, scalable, extensive family of air quality models to be provided by the Models-3 system to its users. The paper is concerned with the last of these, the model engineering problem.
