Nanchang's air quality reflects the flat Jiangxi Gan River delta's Poyang Lake plain position, with vehicle traffic on surrounding expressways and the automotive, aviation, and manufacturing corridor contributing local sources. The Poyang Lake provides limited waterway ventilation, while winter anticyclonic inversions concentrate industrial and heating emissions and Nanchang generally maintains moderate Jiangxi provincial capital readings throughout most of the year.

When is air pollution at its worst in Nanchang?
In Nanchang, traffic emissions, aviation activity from the nearby airport, as well as manufacturing and food processing are the main local sources, with conditions worsening 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 Nanchang 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.
