Qujing's air quality reflects the Yunnan Plateau's Nanpan River valley at 1,874 metres, with vehicle traffic on surrounding expressways and the coal mining, steel, and chemical corridor contributing local sources. The elevated plateau position aids dispersal on most days, while coal mining dust and industrial heating generate elevated emissions and the surrounding Yunnan highland topography creates variation, maintaining moderate Yunnan provincial industrial readings throughout the year.

Frequently Asked Questions
Is air quality bad in Qujing right now?
On 10 August 2026, overall air quality in Qujing is fair. AQI is the main air quality indicator at 39.2/100. Pollution peaks around 11:00 PM (NO2: 39.2/100).
Will air quality be worse tomorrow in Qujing?
On 11 August 2026, air quality conditions in Qujing will be similar to today, with O3 forecast at fair at 36.7/100. Pollution peaks around 11:00 PM (NO2: 45.4/100).
When is air pollution at its worst in Qujing?
Pollution in Qujing typically rises when vehicle traffic, heavy industrial and chemical processing, along with mining and quarrying operations combine, especially once dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. Residential heating through the colder months is a major seasonal source of particulates.
Are air quality levels in Qujing 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
