Yanjiang's air quality reflects the Sichuan Basin's Yanjiang River valley position near Ziyang, with vehicle traffic on surrounding expressways and the chemical, glass, and manufacturing corridor contributing local sources. The Sichuan Basin's topographic enclosure creates concentration under winter inversions, while the broader Chengdu metropolitan industrial background influences the corridor and the area generally maintains moderate Sichuan Basin provincial readings throughout most of the year.

Will air quality be worse tomorrow in Yanjiang?
On 11 August 2026, air quality conditions in Yanjiang will be similar to today, with AQI forecast at very poor at 96.5/100. Pollution peaks around 6:00 AM (NO2: 96.5/100).
When is air pollution at its worst in Yanjiang?
Air quality in Yanjiang tends to be worse when road traffic, petrochemical and refining operations, and light manufacturing build up and temperature inversions set in over the valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. These wind events can carry dust in from the surrounding arid landscape.
Are air quality levels in Yanjiang 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.
