Cuernavaca's air quality reflects the Morelos plateau basin at 1,511 metres surrounded by the Sierra Nevada and Tepozteco mountains, with vehicle traffic on surrounding roads and the tourism, services, and residential corridor contributing local sources. The basin's partial topographic enclosure creates concentration under inversions, while the elevated altitude worsens ozone formation and Cuernavaca generally maintains moderate Mexican highland valley resort city readings throughout most of the year.

When is air pollution at its worst in Cuernavaca?
In Cuernavaca, vehicle traffic and seasonal tourism traffic are the main local sources, with conditions worsening when calm, stagnant conditions settle in the surrounding valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. Heat and sunlight combine with emissions to form ozone at ground level.
Are air quality levels in Cuernavaca 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.
