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.

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.
