The basic question still exists as to what type of model to use and the validity of the predictions. Some of the data that affect the credibility of model predictions are dependent upon the type of model, type of pollutant, averaging time, emission inventory, method of calibration, and meteorological data. Any modeling approach is, of course, dependent on the accuracy and completeness of available input data. The degree of detail required for such data will vary depending on the model. Therefore, the selection of the model has three general steps: (1)Determination of the necessary spatial and temporal resolution; (2)listing of the models that will meet the requirements; and (3)determination of the available data. In determining the desired model resolution, one must define the goals or objectives of the modeling effort. Typically, the goals are to determine the ground-level concentrations resulting from the operation of a particular pollutant source and to compare that source's impact with applicable air-quality standards.
