Regional air quality production systems

The CAMS regional services are provided using a multi-model ensemble approach. Currently seven individual state-of-the-art systems are used in the operational ensemble. Using such an approach, it is possible to derive products that are more robust and are of overall better quality than the individual systems. The main products delivered are daily analyses and four-day forecasts, as well as reanalyses of previous years' surface air quality observations.
