Yunfu's air quality reflects the Guangdong western Xun River valley's partial enclosure between the Yunwu Mountains, with vehicle traffic on surrounding expressways and the marble quarrying, nonferrous metals, and manufacturing corridor generating elevated mineral dust PM10. Consistent South China Sea trade winds provide seasonal ventilation, while the marble quarrying operations' distinctive stone dust represents Yunfu's most locally unique air quality contribution and valley inversions create seasonal concentration throughout the year.

When is air pollution at its worst in Yunfu?
In Yunfu, vehicle traffic, quarrying activity, along with light manufacturing are the main local sources, with conditions worsening when temperature inversions set in over the valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. Dust carried on these winds adds substantially to particulate levels.
Are air quality levels in Yunfu 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.
