Sanming's air quality reflects the Fujian western Sha River valley's partial enclosure between the Wuyi Mountains foothills, with vehicle traffic on surrounding expressways and the steel, chemical, and paper corridor contributing elevated industrial PM2.5. The surrounding mountain ranges create topographic variation, while the industrial corridor's steel and chemical character represents Sanming's most distinctive local air quality contribution and winter valley inversions create seasonal concentration throughout the year.

When is air pollution at its worst in Sanming?
Air quality in Sanming tends to be worse when vehicle traffic along with heavy industrial and chemical processing build up and temperature inversions set in over the valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher.
Are air quality levels in Sanming 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.
