Zhoushan's air quality benefits from its exceptional Zhejiang archipelago East China Sea island position, with consistent East China Sea and Taiwan Strait maritime breezes providing outstanding ventilation. Vehicle traffic and fishing port, port, and logistics operations contribute local sources, while the extraordinary island coastal exposure generally maintains Zhoushan among China's cleaner major coastal island environments throughout most of the year.

When is air pollution at its worst in Zhoushan?
In Zhoushan, vehicle traffic along with port and shipping activity are the main local sources, with conditions worsening when the sea breeze weakens. 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 Zhoushan 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.
