Yancheng's air quality reflects the flat Jiangsu Yellow Sea coastal plain position, with vehicle traffic on surrounding expressways and the automotive, chemical, and agricultural processing corridor contributing local sources. Yellow Sea breezes provide coastal ventilation, while winter anticyclonic inversions concentrate industrial and heating emissions and Yancheng generally maintains moderate Jiangsu coastal provincial readings, with the coastal position providing marginally better ventilation than inland Jiangsu cities.

When is air pollution at its worst in Yancheng?
In Yancheng, traffic on the surrounding roads, petrochemical and refining operations, as well as agricultural burning are the main local sources, with conditions worsening when windblown dust events occur. These wind events can carry dust in from the surrounding arid landscape. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Yancheng 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.
