Changzhou's air quality reflects the flat Yangtze delta plain's Jiangsu position, with vehicle traffic on surrounding expressways and the automotive, pharmaceutical, and manufacturing corridor contributing local sources. East China Sea breezes provide limited maritime ventilation, while winter anticyclonic inversions concentrate industrial and heating emissions and Changzhou generally maintains moderate to elevated Yangtze Delta Jiangsu corridor readings throughout most of the year.

When is air pollution at its worst in Changzhou?
In Changzhou, vehicle traffic and manufacturing and food processing are the main local sources, with conditions worsening when dry spells bring strong winds. These wind events can carry dust in from the surrounding arid landscape. Sea breezes typically keep conditions in check, except during still weather.
Are air quality levels in Changzhou 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.
