8.10 Long-Term One-Atmosphere CMAQ Modeling in Central California: Model Performance Evaluation

摘要

Techniques for evaluating model performance for long-term (i.e., annual) air quality simulations are needed for use in regulatory modeling applications. This study applies numerous evaluation techniques to results of a 14-month simulation in California. Traditional evaluation approaches are shown to be useful for defining model performance criteria and providing an overview of model performance. Spectral decomposition methods and evaluations of spatial correlations can isolate temporal and spatial scales with characteristic model performance. Mechanistic and chemical-ratio evaluations indicate needs for model process development. Future work will focus on combining the various evaluation techniques into a single cohesive model evaluation framework.
