Tongren's air quality reflects the Guizhou eastern Jinjiang River valley's partial enclosure in the karst highland at 279 metres, with vehicle traffic on surrounding expressways and the manganese mining, mercury legacy, and agricultural corridor contributing elevated heavy metal PM2.5. The surrounding Wuling Mountains create topographic variation, while the historic mercury mining legacy represents Tongren's most distinctive industrial air quality heritage and the karst valley topography creates seasonal concentration throughout the year.

When is air pollution at its worst in Tongren?
Tongren usually sees its poorest air quality when traffic emissions, quarrying activity, and farming and agricultural processing coincide with periods when dry spells bring strong winds. These wind events can carry dust in from the surrounding arid landscape. This is most noticeable during spring and autumn wind events.
Are air quality levels in Tongren 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.
