This paper describes a finite-volume grid refinement technique and its application to the Dutch Smog Prediction Model. This technique is used to improve the numerical quality of the model calculations, especially in areas with large spatial gradients (for example in regions with strong emissions) and areas of interest (to be specified by the user). To illustrate the effect of the refinement strategy, results of model computations and comparisons with measurements are presented.
