A user's guide has been assembled to describe the purpose, design, and operation of the COMPLEX/PFM air quality modeling system. The system combines the features of the Potential Flow Model (PFM) with those of the EPA COMPLEX I and Complex II models to produce a potential flow complex terrain model for routine application. Potential flow dispersion calculations may be selected as an option within COMPLEX/PFM. When this option is selected, the model requires hourly wind speed and temperature profiles in order to calculate hourly mixing heights, hourly plume rise (using a layered plume rise equation), and hourly values of the critical dividing streamline height. A preprocessor is provided to interpolate hourly profile data from morning and evening radiosonde data.
