Nanchong's air quality reflects the Sichuan Basin's Jialing River valley at 309 metres, with vehicle traffic on surrounding expressways and the natural gas, silk, and manufacturing corridor contributing local sources. The Sichuan Basin's topographic enclosure creates concentration under winter inversions, while summer monsoon ventilation provides seasonal relief and Nanchong generally maintains moderate Sichuan Basin provincial readings throughout the year.

When is air pollution at its worst in Nanchong?
Nanchong usually sees its poorest air quality when traffic on the surrounding roads and textile and manufacturing operations coincide with periods when temperature inversions set in over the valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. Rains during the wetter months typically wash pollutants out of the air.
Are air quality levels in Nanchong 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.
