The Netherlands air quality today The AQI right now, city by city

Right now the 25 cities Airleaf measures in The Netherlands average AQI 81 (moderate). The worst air is in Zwolle, at AQI 112, and the cleanest in Maastricht, at AQI 41. At ground stations alone, which measure rather than estimate, the average is AQI 82 across 24 cities. 24% of the 25 measured cities are over AQI 100 today, where the air stops being fine for sensitive groups, and 4% have Good air.

Zwolle, at AQI 112 (Unhealthy for sensitive groups) on the US EPA index. Sensitive groups should limit long or intense outdoor activity.

Maastricht, at AQI 41 (Good). Both lists rank current readings, from ground stations wherever The Netherlands has at least three cities with one.

It depends on the city. 1 city is Good, 18 cities are Moderate, 6 cities are Unhealthy for sensitive groups. At the national average of AQI 81: Unusually sensitive people should consider limiting long outdoor exertion.

About 33,800 ha from 2001 to 2025, 6% of the forest it had in 2000, from the University of Maryland's yearly satellite maps of forest loss. 3,940 ha of it was cleared for good, for farms, mines or towns.

Amersfoort, with 35.6% tree cover within 2 km of its center, measured from Sentinel-2 satellite images.

Each city's reading is the US EPA air quality index, from ground monitoring stations where one has reported recently nearby, and from the CAMS atmospheric model elsewhere; each city's report says which. Tree cover is measured over the same 2 km radius in every city, so the cities compare like for like.
