- Responsibility for the design, implementation and interpretation of an evaluation of the Regional Acid Deposition Model and the Acid Deposition and Oxidant Model was given to the Model Evaluation Team. This paper presents lessons learned from the design and implementation of the Eulerian Model Evaluation Field Study (EMEFS) protocol for model evaluation, and the interpretation of evaluation results. These lessons can benefit future model evaluation efforts. The EMEFS model evaluation protocol required a blend of operational and diagnostic testing to meet the needs of the applications of the model(s). Multiple tests and tests over multiple chemical systems were needed to stress the model and gain diagnostic insight into model performance. The protocol provided a frame of reference but not rigid procedures for testing the models. Scatter plots comparing model output with observations that included a tendency line an confidence intervals were found most informative. Spatial commensurability between observations and simulations was much more difficult to achieve than temporal commensurability. We found that fundamental features of the design of the model give rise to inherent biases in comparisons to observations. Participation of model developers allowed for rapid modification of models in response to evaluation findings. The combination of operational and diagnostic evaluation and close involvement of model developers in the evaluation process made possible a complete cycle of evaluation, revision, and retesting before the model was applied.
