Base case model evaluation

The model evaluation for the base case model run was undertaken using USEPA1 statistical criteria. It was found that all the performance metrics were within the limits set by the EPA performance criteria. Further details of model evaluation and validation can be obtained from the model evaluation report by ENVIRON.16 The model does underpredict ozone concentrations at an observational site in the coastal region of Corpus Christi but on the days of highest ozone concentrations it performs relatively well as shown in Fig. 2. The model behaves satisfactorily in the inland areas of San Antonio and Austin, and it meets the EPA-prescribed performance metrics. The future case modeling simulations were accomplished after base case validation to test the impact of emission control strategies.
