On Coupling Air Pollution Transport Models of Different Scales

  • Ulrich Damrath

The effect of coupling a coarse-grid and a fine-grid air pollution transport model (by one-way interaction) is investigated. For this, the application of ‘coarse’ boundary values (provided by a coarse-grid model) in the fine-grid model is discussed theoretically and demonstrated by test calculations. It turns out that one should always prefer applying coarse information about external (with respect to the fine-grid model) sources to ignoring them.
