4.12 Model Evaluation of Regional Chemistry Transport Models

摘要

In Europe, over the last decade several model intercomparison and model evaluation studies have been carried out. Using several models in a model evaluation study has the clear advantage that the model results are not just compared to observations, but that the models are also tested against each other. Model evaluation studies have been performed first for ozone, but more recently also for PM, and the components of PM. In general, the studies have been focused on the overall model performance, without focussing on specific processes. The studies show that most CTM's are capable of simulation ozone concentrations, but that there are still major problems with modelling PM.
