Dadukou's air quality reflects the Sichuan Basin's Chongqing western Jialing River valley position, with vehicle traffic on surrounding roads and the steel and manufacturing corridor contributing elevated industrial PM2.5. The Sichuan Basin's topographic enclosure creates concentration under winter inversions, while the broader Chongqing metropolitan industrial background influences the corridor and the area generally maintains moderate to elevated Chongqing metropolitan western corridor readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Dadukou right now?
On 10 August 2026, overall air quality in Dadukou is poor. AQI is the main air quality indicator at 78.8/100. Pollution peaks around 11:00 PM (NO2: 78.8/100).
Will air quality be worse tomorrow in Dadukou?
On 11 August 2026, air quality conditions in Dadukou will be worse than today, with AQI forecast at very poor at 84.3/100. Pollution peaks around 2:00 AM (NO2: 84.3/100).
When is air pollution at its worst in Dadukou?
Pollution in Dadukou typically rises when traffic emissions, heavy industrial and chemical processing, together with manufacturing and food processing combine, especially once the surrounding valley traps air close to the ground. Topographic enclosure in the valley lets pollution accumulate rather than clear out. Dust carried on these winds adds substantially to particulate levels.
Are air quality levels in Dadukou 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.
