Hai'an's air quality reflects the flat Jiangsu northern Yangtze delta coastal plain position, with vehicle traffic and the mechanical manufacturing and agricultural corridor contributing local sources. East China Sea breezes provide limited maritime ventilation, while winter anticyclonic inversions concentrate emissions and Hai'an generally maintains moderate Jiangsu coastal northern corridor readings throughout most of the year.

When is air pollution at its worst in Hai’an?
Air quality in Hai’an tends to be worse when traffic on the surrounding roads, light manufacturing, together with crop farming build up and the sea breeze weakens. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Hai’an 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.
