Review of the requirements for models and model applications
Requirements for models and model applications are reviewed on basis of the Dobris Assessment report and the practice in EU legislation and international organisations, and from the responses of a questionnaire sent to 38 European countries. Model applications are frequently used for regulatory and general assessment purposes by various users (scientists, air quality managers, policy-makers). Forecast models may play an important role in informing the public about smog episodes. While requirements in terms of compounds and spatial and temporal scales can be provided, the requirements on accuracy and documentation of models are less well defined.
