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.

Will air quality be worse tomorrow in Yutan?
On 11 August 2026, air quality conditions in Yutan will be similar to today, with AQI forecast at fair at 25.9/100. Pollution peaks around 3:00 AM (O3: 25.9/100).
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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
