Jiancheng in Sichuan reflects the Sichuan Basin's interior valley position, with vehicle traffic on surrounding roads and agricultural and light manufacturing operations contributing local sources. The Sichuan Basin's topographic enclosure creates concentration under winter inversions, while the regional Sichuan industrial background influences the corridor and the area generally maintains moderate Sichuan Basin provincial readings throughout most of the year.

When is air pollution at its worst in Jiancheng?
In Jiancheng, traffic emissions, manufacturing and food processing, together with agricultural activity are the main local sources, with conditions worsening when temperature inversions set in over the valley. 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 Jiancheng 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.
