Ciudad Guzmán's air quality reflects the Jalisco Colima Valley's enclosed basin at 1,520 metres at the base of the Nevado de Colima, with vehicle traffic on surrounding roads and the agricultural, services, and government corridor contributing local sources. The surrounding Sierra Madre Occidental and the Colima volcanic complex create significant topographic enclosure, while winter inversions in the enclosed highland valley and the proximity to the active Volcán de Colima's occasional SO₂ emissions maintain moderate to elevated Mexican western highland valley readings throughout most of the year.

When is air pollution at its worst in Ciudad Guzmán?
The biggest local contributors to pollution in Ciudad Guzmán are vehicle traffic along with farming and agricultural processing, particularly once temperature inversions set in over the valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. The effect is strongest during the colder months, when inversions set in most often.
Are air quality levels in Ciudad Guzmán 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.
