Xiashi in China reflects the flat Zhejiang coastal plain position adjacent to Haining, with vehicle traffic and light manufacturing and textile corridor contributing local sources. East China Sea breezes provide maritime ventilation, while winter anticyclonic inversions concentrate emissions and the area generally maintains moderate Zhejiang coastal corridor readings throughout most of the year.

When is air pollution at its worst in Xiashi?
The biggest local contributors to pollution in Xiashi are traffic on the surrounding roads as well as textile and manufacturing operations, particularly once the sea breeze weakens. Sea breezes typically keep conditions in check, except during still weather. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Xiashi 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.
