Zhenjiang's air quality reflects the flat Yangtze River valley's Jiangsu southern bank position, with vehicle traffic on surrounding expressways and the chemical, paper, and logistics corridor contributing local sources. The Yangtze River provides limited waterway ventilation, while winter anticyclonic inversions concentrate industrial and heating emissions and Zhenjiang generally maintains moderate Jiangsu Yangtze corridor provincial readings throughout most of the year.

When is air pollution at its worst in Zhenjiang?
Pollution in Zhenjiang typically rises when traffic emissions along with heavy industrial and chemical processing combine, especially once the surrounding valley traps air close to the ground. The bowl-like terrain here limits how quickly pollutants can escape. Dust carried on these winds adds substantially to particulate levels.
Are air quality levels in Zhenjiang 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.
