Chiapa de Corzo's air quality reflects the Chiapas Central Depression's enclosed Grijalva River valley basin adjacent to Tuxtla Gutiérrez at 440 metres, with vehicle traffic on surrounding roads and the tourism, lacquerware crafts, and agricultural corridor contributing local sources. The valley's topographic enclosure creates concentration under inversions, while the tropical climate's seasonal rain provides periodic cleansing and Chiapa de Corzo generally maintains moderate Mexican southern highland valley readings throughout most of the year.

When is air pollution at its worst in Chiapa de Corzo?

Pollution in Chiapa de Corzo typically rises when road traffic, farming and agricultural processing, along with tourism-related traffic combine, especially once the surrounding valley traps air close to the ground. Topographic enclosure in the valley lets pollution accumulate rather than clear out. This tends to happen most in winter, when inversions are most common.

Are air quality levels in Chiapa de Corzo 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.
