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.

Frequently Asked Questions
Is air quality bad in Nanchong right now?

Will air quality be worse tomorrow in Nanchong?
On 11 August 2026, air quality conditions in Nanchong will be better than today, with PM1 forecast at fair at 34.1/100. Pollution peaks around 12:00 AM (NO2: 53.2/100).
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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
