Yibin's air quality reflects the Sichuan Basin's southern Jinsha River confluence at 340 metres, with vehicle traffic on surrounding expressways and the coal mining, liquor — Yibin being China's liquor capital with Wuliangye distillery — and manufacturing corridor contributing distinctive organic fermentation aerosols alongside primary vehicle sources. The Sichuan Basin's topographic enclosure creates concentration under winter inversions, while the liquor distilling operations add a uniquely characteristic local air quality signature throughout the year.

When is air pollution at its worst in Yibin?
The biggest local contributors to pollution in Yibin are traffic on the surrounding roads, mining operations, and manufacturing activity, particularly once the surrounding valley traps air close to the ground. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. Residential heating through the colder months is a major seasonal source of particulates.
Are air quality levels in Yibin 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.
