Guangyuan's air quality reflects the Sichuan Basin's northern Jialing River valley entrance position between the Qinling foothills at 488 metres, with vehicle traffic on surrounding expressways and the agricultural, manufacturing, and reconstruction corridor contributing local sources. The Jialing valley's topographic enclosure creates concentration under inversions, while the northern corridor's lower industrial intensity compared to the Chengdu metropolitan core generally maintains moderate Sichuan northern gateway readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Guangyuan right now?
On 19 August 2026, overall air quality in Guangyuan is fair. PM1 is the main pollutant at 31.2/100. Pollution peaks around 2:00 PM (O3: 57.1/100).
Will air quality be worse tomorrow in Guangyuan?
On 20 August 2026, air quality conditions in Guangyuan will be similar to today, with PM1 forecast at fair at 27.3/100. Pollution peaks around 12:00 PM (O3: 60.0/100).
When is air pollution at its worst in Guangyuan?
Pollution in Guangyuan typically rises when traffic on the surrounding roads, manufacturing activity, together with ongoing construction work combine, especially once temperature inversions set in over the valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. Dust carried on these winds adds substantially to particulate levels.
Are air quality levels in Guangyuan 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.
