Coatzacoalcos's air quality faces significant challenges from the flat Veracruz tropical coastal plain position, with the PEMEX petrochemical complex — Mexico's largest petrochemical industrial hub — generating elevated industrial SO₂, benzene, and VOCs alongside vehicle traffic on surrounding roads. Gulf of Mexico breezes provide warm-season ventilation, while the extraordinary petrochemical complex's scale makes Coatzacoalcos Mexico's most distinctively petrochemical-defined coastal urban air quality environment throughout the year.

When is air pollution at its worst in Coatzacoalcos?
Air quality in Coatzacoalcos tends to be worse when traffic on the surrounding roads along with heavy industry such as steel, cement, or petrochemical processing build up and windblown dust events occur. Dust carried on these winds adds substantially to particulate levels. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Coatzacoalcos 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.
