Chilpancingo's air quality reflects the Guerrero Sierra Madre del Sur's Huacapa River valley at 1,360 metres, with vehicle traffic on surrounding roads and the government, services, and agricultural corridor contributing local sources. The surrounding mountain ranges create topographic enclosure, while winter inversions in the enclosed mountain valley create seasonal challenges and Chilpancingo generally maintains moderate Mexican southern highland valley capital readings throughout most of the year.

When is air pollution at its worst in Chilpancingo?

Pollution in Chilpancingo typically rises when road traffic as well as agricultural burning combine, especially once the surrounding valley traps air close to the ground. The bowl-like terrain here limits how quickly pollutants can escape. This tends to happen most in winter, when inversions are most common.

Are air quality levels in Chilpancingo 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.
