Meishan in China — noting this location appears twice in the database — reflects the Sichuan Basin's Minjiang River valley south of Chengdu, with vehicle traffic on surrounding roads and the pharmaceutical, paper, and agricultural corridor contributing local sources. The Sichuan Basin's topographic enclosure creates concentration under winter inversions, while the broader Chengdu metropolitan industrial background influences the corridor and the area generally maintains moderate Sichuan Basin provincial readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Meishan right now?
On 10 August 2026, overall air quality in Meishan is poor. AQI is the main air quality indicator at 75.3/100. Pollution peaks around 1:00 PM (O3: 75.3/100).
Will air quality be worse tomorrow in Meishan?
On 11 August 2026, air quality conditions in Meishan will be better than today, with AQI forecast at fair at 25.2/100. Pollution peaks around 12:00 AM (O3: 25.2/100).
When is air pollution at its worst in Meishan?
Pollution in Meishan typically rises when road traffic along with agricultural activity combine, especially once calm, stagnant conditions settle in the surrounding valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher.
Are air quality levels in Meishan 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.
