Air quality in Ypenburg estimated
South Holland, The Netherlands. No ground monitor we can use is in this city, so these numbers are model estimates, not measurements.
≈ 10 µg/m³
Moderate
Estimated PM2.5, 7-day average to 2026-09-30, about 0.6× the WHO 24-hour guideline. 30-day average ≈ 8 µg/m³.
Model estimate from the Copernicus Atmosphere Monitoring Service (CAMS), scaled by 0.82 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.
