Dali in Yunnan reflects the Yunnan plateau's Erhai Lake basin at 1,975 metres with the Cang Mountain backdrop, with vehicle traffic and Bai ethnic heritage tourism and agricultural corridor contributing local sources. Consistent plateau winds and lake breezes provide reliable ventilation and Dali generally maintains good to moderate conditions for a Chinese highland UNESCO heritage lake city throughout most of the year.

When is air pollution at its worst in Dali?
Air quality in Dali tends to be worse when vehicle traffic, crop farming, along with seasonal tourism traffic build up and still air allows pollutants to build up. Local weather patterns add further variation on top of these sources. Conditions can otherwise vary considerably with the weather.
Are air quality levels in Dali 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.
