Qianxi in Guizhou reflects the Guizhou Plateau's karst highland position at 860 metres, with vehicle traffic on surrounding roads and the coal mining and light manufacturing corridor contributing local sources. The elevated karst plateau position aids dispersal on most days, while coal mining dust and residential coal burning generate elevated PM2.5 under basin inversions and the surrounding Guizhou karst topography creates variation throughout most of the year.

Frequently Asked Questions
Is air quality bad in Qianxi right now?
On 10 August 2026, overall air quality in Qianxi is fair. NO2 is the main pollutant at 37.9/100. Pollution peaks around 5:00 PM (O3: 58.7/100).
Will air quality be worse tomorrow in Qianxi?
On 11 August 2026, air quality conditions in Qianxi will be worse than today, with AQI forecast at poor at 62.6/100. Pollution peaks around 11:00 AM (O3: 62.6/100).
When is air pollution at its worst in Qianxi?
The biggest local contributors to pollution in Qianxi are road traffic, mining and quarrying operations, along with textile and manufacturing operations, particularly once the surrounding valley traps air close to the ground. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. These wind events can carry dust in from the surrounding arid landscape.
Are air quality levels in Qianxi 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.
