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

Right now the 639 cities Airleaf measures in China average AQI 112 (unhealthy for sensitive groups). The worst air is in Suihua, at AQI 294, and the cleanest in Baoshan, Yunnan, at AQI 17. At ground stations alone, which measure rather than estimate, the average is AQI 114 across 433 cities. 52% of the 639 measured cities are over AQI 100 today, where the air stops being fine for sensitive groups, and 4% have Good air.

Suihua, at AQI 294 (Very unhealthy) on the US EPA index. Health alert — everyone should avoid long outdoor exertion.

Baoshan, Yunnan, at AQI 17 (Good). Both lists rank current readings, from ground stations wherever China has at least three cities with one.

It depends on the city. 27 cities are Good, 282 cities are Moderate, 185 cities are Unhealthy for sensitive groups, 128 cities are Unhealthy, 12 cities are Very unhealthy, 5 cities are Hazardous. At the national average of AQI 112: Sensitive groups should limit long or intense outdoor activity.

About 13.5 million ha from 2001 to 2025, 8% of the forest it had in 2000, from the University of Maryland's yearly satellite maps of forest loss. 2.24 million ha of it was cleared for good, for farms, mines or towns.

Fenghuang, with 80.9% 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.
