Heerenveen, known locally as a meadow and forest-edge town, sees air quality conditions typical of Fryslân, where traffic along the A32 and nearby industry are the chief contributors to local pollution. the Friese meadows and Skoatterwald forest nearby helps with dispersal, and the town's exposure to the speed-skating heartland of Fryslân keeps conditions broadly in line with typical Dutch levels through most of the year.

When is air pollution at its worst in Heerenveen?
Heerenveen tends to see its biggest air quality dips during spring and the start of summer, when birch, oak, and alder pollen peaks, or on still, warm days when traffic on the A32 and industry emissions linger; wide-open Frisian grassland and lake breezes keep the air moving. Outside these windows, conditions in Heerenveen rarely stray far from the national average.
Are air quality levels in Heerenveen 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.
