Rui'an's air quality benefits from the Zhejiang southern coastal Wenrui Plain position, with consistent East China Sea breezes providing maritime ventilation. Vehicle traffic on surrounding expressways and the automotive parts, plastics, and manufacturing corridor contribute local sources, while the coastal maritime exposure generally maintains Rui'an among Zhejiang's more moderately ventilated coastal industrial cities throughout most of the year.

When is air pollution at its worst in Rui’an?
Pollution in Rui’an typically rises when vehicle traffic together with light manufacturing combine, especially once 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 Rui’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.
