Abstract Currently there are no standardized guidelines for evaluating the performance of air quality simulation models. In this report a conceptual framework for objectively evaluating model performance is developed. Five attributes of a well-behaving model are defined: accuracy of the peak prediction, absence of systematic bias, lack of gross error, temporal correlation, and spatial alignment. The relative importance of these attributes is shown to depend on the issue being addressed and the pollutant being considered. Acceptability of model behavior is determined by calculating several perofrmance measures and comparing their values with specific standards. Comprehensive background material is presented on the elements of the performance evaluation problem: the types of issues to be addressed; the classes of models to be used along with the applications for which they are suited; and the categories of performance measures available for consideration. Also, specific rationales are developed on which performance standards could be based. Guidance on the interpretation of performance measure values is provided by means of an example using a large, grid-based air quality model.
