Zunyi's air quality reflects the Guizhou Plateau's Louzhan River valley at 844 metres, with vehicle traffic on surrounding expressways and the tobacco, aluminium, and manufacturing corridor contributing local sources. The elevated plateau position aids dispersal on most days, while winter coal heating under valley inversions generates elevated PM2.5 and the surrounding Guizhou karst topography creates distinctive local wind patterns throughout most of the year.

When is air pollution at its worst in Zunyi?
Pollution in Zunyi typically rises when traffic on the surrounding roads and textile and manufacturing operations combine, especially once the surrounding valley traps air close to the ground. The bowl-like terrain here limits how quickly pollutants can escape. Coal and wood used for winter heating add substantially to particulate levels.
Are air quality levels in Zunyi 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.
