Leiyang's air quality reflects the Hunan southeastern Leiyang River valley's partial enclosure, with vehicle traffic on surrounding roads and the coal mining, tungsten, and agricultural corridor contributing local sources. The surrounding Hengshan and Qiyang hills create modest topographic variation, while winter coal heating under valley inversions generates elevated PM2.5 and the regional Hunan industrial background maintains moderate to elevated Hunan southeastern corridor readings throughout the year.

When is air pollution at its worst in Leiyang?
Leiyang usually sees its poorest air quality when road traffic, quarrying activity, and farming and agricultural processing coincide with periods when 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 Leiyang 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.
