Yutan in Hunan reflects the Hunan central Zi River valley position, with vehicle traffic on surrounding roads and agricultural and light manufacturing contributing local sources. Winter coal heating under valley inversions generates elevated PM2.5, while the regional Hunan industrial background influences readings and the valley's topographic variation creates modest concentration under calm conditions throughout the year.

When is air pollution at its worst in Yutan?
Yutan usually sees its poorest air quality when road traffic, manufacturing and food processing, along with agricultural activity coincide with periods when the surrounding valley traps air close to the ground. The bowl-like terrain here limits how quickly pollutants can escape. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher.
Are air quality levels in Yutan 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.
