Longyan's air quality reflects the Fujian western mountainous Tingjiang River valley's partial enclosure between the Wuyi and Bopin mountains, with vehicle traffic on surrounding expressways and the copper mining and industrial and manufacturing corridor contributing local sources. The surrounding mountain ranges create significant topographic variation, while the copper mining operations add distinctive mineral dust PM10 and Longyan generally maintains moderate Fujian western mountain corridor readings throughout most of the year.

When is air pollution at its worst in Longyan?
The biggest local contributors to pollution in Longyan are traffic emissions, quarrying activity, as well as light manufacturing, particularly once windblown dust events occur. Dust carried on these winds adds substantially to particulate levels. These episodes tend to cluster in spring and autumn.
Are air quality levels in Longyan 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.
