Aarhus's air quality is generally good, benefiting from consistent North Sea and Baltic westerlies providing reliable maritime ventilation across Denmark's second city. The Port of Aarhus container terminal contributes shipping emissions along the harbour corridor, while vehicle traffic on the surrounding motorway network is the primary urban source. The flat Danish coastal plain and consistent Atlantic airflows generally prevent significant pollution accumulation, keeping Aarhus readings among the better values for a major northern European port city.

Are air quality levels in Aarhus based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
