Apaseo el Grande's air quality reflects the flat Guanajuato Bajío plateau at 1,750 metres adjacent to Celaya, with vehicle traffic on surrounding roads and the automotive manufacturing — Apaseo hosting the Toyota Bajío plant — and agricultural corridor contributing elevated automotive industrial emissions. The elevated plateau position aids dispersal on most days, while winter inversions create modest seasonal challenges and the Toyota manufacturing operations represent the most distinctive local emission source throughout most of the year.

When is air pollution at its worst in Apaseo el Grande?
Pollution in Apaseo el Grande typically rises when traffic emissions, textile and manufacturing operations, as well as farming and agricultural processing combine, especially once windblown dust events occur. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. These episodes tend to cluster in spring and autumn.
Are air quality levels in Apaseo el Grande 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.
