As a Wadden Sea port town within Fryslân, Harlingen's air quality is shaped by its setting, with local industry and A31 traffic together accounting for most urban emissions here. The proximity of the Wadden Sea coast aids ventilation, while the historic ferry port to the Wadden Islands means air quality stays close to typical Dutch averages for most of the year.

When is air pollution at its worst in Harlingen?

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