Kaiyuan in China reflects the Liaoning Province's flat Liao River plain position, with vehicle traffic on surrounding roads and manufacturing and agricultural processing contributing local sources. Winter residential coal heating compounds emissions under frequent anticyclonic inversions, while the flat terrain allows reasonable summer dispersal and Kaiyuan generally maintains moderate to elevated Liaoning Province agricultural industrial corridor readings throughout the winter months.

When is air pollution at its worst in Kaiyuan?
Kaiyuan usually sees its poorest air quality when road traffic, manufacturing activity, and agricultural activity coincide with periods when dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Coal and wood used for winter heating add substantially to particulate levels.
Are air quality levels in Kaiyuan 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.
