As an estuary industrial port town within Groningen, Delfzijl's air quality is shaped by its setting, as vehicles on the N33 and the town's own industry make up the bulk of local emissions. Thanks partly to the Eems estuary and Wadden Sea coast, dispersal stays reasonable, and the chemical-industry sea port keeps year-round conditions close to the Dutch national average.

Apart from these spells, Delfzijl usually sees conditions fairly typical for the country as a whole.
Are air quality levels in Delfzijl 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.
