Aguascalientes' air quality reflects the flat central Mexican plateau basin at 1,888 metres, with vehicle traffic on surrounding roads and the automotive manufacturing, textiles, and agri-food corridor generating elevated industrial and vehicle emissions. The elevated plateau position aids dispersal on most days, while the enclosed valley creates modest inversion episodes and the automotive manufacturing character makes Aguascalientes Mexico's most distinctively automotive industry-defined central plateau metropolitan environment throughout most of the year.

When is air pollution at its worst in Aguascalientes?

The biggest local contributors to pollution in Aguascalientes are road traffic together with manufacturing activity, particularly once the surrounding valley traps air close to the ground. The bowl-like terrain here limits how quickly pollutants can escape. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher.

Are air quality levels in Aguascalientes 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.
