Yichun in Jiangxi reflects the Jiangxi western Yuan River valley's partial enclosure between the Jiugong and Wugong mountain ranges, with vehicle traffic on surrounding expressways and the forestry, lithium mining, and manufacturing corridor contributing local sources. The surrounding mountain ranges create topographic variation, while the lithium battery materials mining represents the most distinctive local industrial emission source and valley inversions create seasonal concentration throughout the year.

Will air quality be worse tomorrow in Yichun?
On 17 July 2026, air quality conditions in Yichun will be similar to today, with O3 forecast at fair at 39.1/100. Pollution peaks around 11:00 PM (NO2: 49.1/100).
When is air pollution at its worst in Yichun?
The biggest local contributors to pollution in Yichun are road traffic, mining operations, along with light manufacturing, particularly once temperature inversions set in over the valley. The bowl-like terrain here limits how quickly pollutants can escape. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher.
Are air quality levels in Yichun 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.
