Tonalá's air quality reflects the greater Guadalajara metropolitan area's southeastern corridor adjacent to Tlaquepaque, with vehicle traffic on surrounding roads and the artisan furniture, ceramics, and manufacturing corridor contributing elevated wood dust and lacquer VOC emissions alongside primary vehicle sources. The Atemajac Valley's topographic enclosure concentrates emissions under inversions, while the artisan manufacturing character creates a distinctive local emission profile and Tonalá shares the broader Guadalajara metropolitan challenges.

When is air pollution at its worst in Tonalá?
The biggest local contributors to pollution in Tonalá are road traffic and manufacturing and food processing, particularly once temperature inversions set in over the valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. These wind events can carry dust in from the surrounding arid landscape.
Are air quality levels in Tonalá 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.
