Chongzuo's air quality reflects the flat Guangxi Zuo River valley's border position with Vietnam, with vehicle traffic on surrounding expressways and the sugarcane processing, border trade, and manufacturing corridor contributing local sources. Consistent South China southerly winds provide seasonal ventilation, while the sugarcane processing's organic emissions add a characteristic signature and Chongzuo generally maintains moderate Guangxi southwestern corridor readings throughout most of the year.

When is air pollution at its worst in Chongzuo?
Pollution in Chongzuo typically rises when traffic on the surrounding roads along with light manufacturing combine, especially once weather conditions turn unfavourable. Background emissions and local weather both shape how conditions change from day to day. Conditions can otherwise vary considerably with the weather.
Are air quality levels in Chongzuo 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.
