Baiyin's air quality reflects the Gansu Yellow River valley's partial enclosure with the White Silver Mountain copper and lead smelter legacy, with vehicle traffic on surrounding roads and the nonferrous metal smelting and chemical corridor generating elevated heavy metal PM2.5. The surrounding Loess Plateau and Yellow River valley create topographic variation, while the smelting operations' distinctive heavy metal particulate legacy represents Baiyin's most historically industrially unique air quality characteristic throughout most of the year.

When is air pollution at its worst in Baiyin?
Air quality in Baiyin tends to be worse when road traffic along with steel, cement, and chemical production build up and dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. These episodes tend to cluster in spring and autumn.
Are air quality levels in Baiyin 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.
