Air quality in Heerenveen, estimated
Friesland, The Netherlands. No ground monitor we can use is in this city, so these numbers are model estimates, not measurements.
Likely between 6 and 14 µg/m³ (33–60 US AQI): the model's 7-day average to 3 Oct 2026, about 0.6× the WHO 24-hour guideline.
30-day average, estimated: ≈ 7 µg/m³
Model estimate from the Copernicus Atmosphere Monitoring Service (CAMS), scaled by 0.76 to match 10 measured cities within 300 km over the last week. Adjusted this way, a single day lands within ×1.5 of what a monitor would read about two times in three: a guide, not a measurement. Not ranked on SmogRank's boards.
