Wenzhou's air quality benefits from its Zhejiang southern coastal position on the Ou River delta, with consistent East China Sea and Taiwan Strait breezes providing reliable maritime ventilation. Vehicle traffic on surrounding expressways and the footwear, electrical components, and manufacturing corridor contribute local sources, while the coastal maritime exposure generally maintains Wenzhou among Zhejiang's more moderately ventilated coastal provincial cities throughout most of the year.

When is air pollution at its worst in Wenzhou?
Wenzhou usually sees its poorest air quality when road traffic and light manufacturing coincide with periods when onshore breezes fall calm. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Wenzhou 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.
