Operational air pollution forecasts from European to local scale

Abstract

A new operational air pollution forecast system, THOR, has been developed at the National Environmental Research Institute, Denmark. The integrated system consists of a series of air pollution models, covering a wide range of scales (from European scale to street scale in cities) and applications. The system is designed to automatically produce 3 days air pollution forecasts of the most important air pollution species on different scales on a continuous basis. The various models, the coupling/integration and the configuration of the models, the visualizations and the real-time performance on fast workstations with parallel architecture will be described. Some examples of model results and validations on street level are presented.
