Mianyang's air quality reflects the Sichuan Basin's Fujiang River valley at 472 metres, with vehicle traffic on surrounding expressways and the electronics, military technology, and manufacturing corridor contributing local sources. The Sichuan Basin's topographic enclosure creates concentration under winter inversions, while the defence technology and electronics character creates a distinctive industrial emission profile and Mianyang generally maintains moderate Sichuan Basin provincial readings throughout the year.

When is air pollution at its worst in Mianyang?
In Mianyang, traffic on the surrounding roads, military aviation activity, and textile and manufacturing operations are the main local sources, with conditions worsening when 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 Mianyang 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.
