Chaoyang in Liaoning reflects the Liaoning western Daling River valley position, with vehicle traffic on surrounding expressways and the cement, metallurgy, and agricultural corridor contributing local sources. Winter residential coal heating compounds industrial emissions under frequent anticyclonic inversions, while the surrounding Liaoning hills create topographic variation and Chaoyang generally maintains moderate Liaoning western provincial readings throughout most of the year.

When is air pollution at its worst in Chaoyang?
In Chaoyang, road traffic, petrochemical and refining operations, together with farming and agricultural processing are the main local sources, with conditions worsening when 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 Chaoyang 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.
