Zigong's air quality reflects the Sichuan Basin's Tuo River valley position, with vehicle traffic on surrounding expressways and the salt chemical — Zigong being China's salt capital — dinosaur tourism, and manufacturing corridor contributing distinctive salt chemical industrial emissions. The Sichuan Basin's topographic enclosure creates concentration under winter inversions, while the salt chemical operations add a uniquely characteristic industrial emission profile and Zigong generally maintains moderate Sichuan Basin provincial readings throughout most of the year.

When is air pollution at its worst in Zigong?
The biggest local contributors to pollution in Zigong are road traffic, heavy industry such as steel, cement, or petrochemical processing, as well as manufacturing and food processing, particularly once the surrounding valley traps air close to the ground. The bowl-like terrain here limits how quickly pollutants can escape. Dust carried on these winds adds substantially to particulate levels.
Are air quality levels in Zigong 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.
