Xiamen's air quality benefits from its exceptional Fujian coastal island position on the Taiwan Strait, with consistent Taiwan Strait and South China Sea breezes providing reliable and often powerful maritime ventilation. Vehicle traffic on surrounding expressways and the electronics, logistics, and tourism corridor contribute local sources, while the outstanding island coastal exposure and the warm maritime climate generally maintain Xiamen among southeastern China's cleaner major coastal cities throughout most of the year.

Are air quality levels in Xiamen 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.
