Abstract

Quality assurance means all those planned and systematic actions necessary to provide adequate confidence that a product or service will satisfy given requirements for quality, Information is given about new developments concerning model quality assurance of atmospheric dispersion models, in particular about model evaluation, the overall system of procedures designed to measure the model performance, and model validation, the analysis of model performance based on the comparison of model outputs with experimental data. Some quality indicators currently used in model validation exercises are described. Problems related to uncertainty analysis are highlighted.
