Changchun's air quality reflects the flat Jilin Yitong River plain's Northeast China position, with vehicle traffic on surrounding expressways and the FAW automotive manufacturing, chemical, and agricultural corridor generating elevated industrial and vehicle emissions. Winter residential coal heating extensively compounds automotive industrial emissions under frequent anticyclonic inversions, while summer conditions are considerably better and Changchun generally maintains moderate to elevated Northeast China automotive industrial provincial capital readings throughout the winter months.

When is air pollution at its worst in Changchun?
The biggest local contributors to pollution in Changchun are road traffic, steel, cement, and chemical production, along with textile and manufacturing operations, particularly once dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. Fuel burned for winter heating adds an extra layer of particulates on top of other sources.
Are air quality levels in Changchun 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.
