Liaoyuan's air quality reflects the flat Jilin Province's Liaoyuan River valley coal mining position, with vehicle traffic on surrounding roads and the coal mining legacy, manufacturing, and residential heating corridor contributing elevated coal dust PM10. Winter residential coal heating compounds mining background under frequent anticyclonic inversions, while the flat terrain allows reasonable summer dispersal and Liaoyuan generally maintains moderate to elevated Jilin Province coal corridor city readings throughout the winter months.

Frequently Asked Questions

Is air quality bad in Liaoyuan right now?

On 10 August 2026, overall air quality in Liaoyuan is fair. AQI is the main air quality indicator at 31.9/100. Pollution peaks around 12:00 AM (NO2: 31.9/100).

Will air quality be worse tomorrow in Liaoyuan?

On 11 August 2026, air quality conditions in Liaoyuan will be similar to today, with O3 forecast at fair at 26.7/100. Pollution peaks around 10:00 PM (NO2: 41.9/100).

When is air pollution at its worst in Liaoyuan?

Air quality in Liaoyuan tends to be worse when traffic on the surrounding roads, mining and quarrying operations, as well as light manufacturing build up and 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 Liaoyuan 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.
