Colima's air quality reflects the Colima Valley's enclosed position at 491 metres adjacent to the extraordinarily active Volcán de Colima — one of the world's most active volcanoes — with vehicle traffic on surrounding roads and the volcanic SO₂, ash, and particulate emissions adding a major and distinctive geological dimension to vehicle and local industrial sources. The volcanic eruption frequency and the valley's topographic enclosure make Colima Mexico's most distinctively volcanically-influenced major city air quality environment throughout the year.

When is air pollution at its worst in Colima?
Pollution in Colima typically rises when traffic on the surrounding roads, especially once dry spells bring strong winds. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. This is most noticeable during spring and autumn wind events.
Are air quality levels in Colima 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.
