Nantong's air quality reflects the flat Jiangsu Yangtze River mouth position on the northern Yangtze delta, with vehicle traffic on surrounding expressways and the chemical, textile, and manufacturing corridor contributing local sources. The Yangtze estuary and East China Sea provide coastal ventilation, while winter anticyclonic inversions concentrate industrial and heating emissions and Nantong generally maintains moderate Jiangsu coastal northern Yangtze delta readings throughout most of the year.

When is air pollution at its worst in Nantong?
Air quality in Nantong tends to be worse when traffic emissions, steel, cement, and chemical production, as well as manufacturing and food processing build up and windblown dust events occur. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Nantong 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.
