Bazhou in Sichuan reflects the Sichuan Basin's Tongjiang River valley north of Chengdu at Bazhong, with vehicle traffic on surrounding expressways and the agricultural, tourism, and light manufacturing corridor contributing local sources. The Sichuan Basin's topographic enclosure creates concentration under winter inversions, while the surrounding Qinling and Daba mountain backdrop provides scenic variation and Bazhong generally maintains moderate Sichuan Basin provincial readings throughout most of the year.

When is air pollution at its worst in Bazhou?
Air quality in Bazhou tends to be worse when traffic on the surrounding roads, light manufacturing, together with crop farming build up and temperature inversions set in over the valley. The bowl-like terrain here limits how quickly pollutants can escape. The effect is strongest during the colder months, when inversions set in most often.
Are air quality levels in Bazhou 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.
