San Felipe del Progreso's air quality reflects the flat Estado de México Lerma River valley highland position at 2,580 metres in the Mazahua indigenous territory, with vehicle traffic on surrounding roads and the agricultural and services character contributing modest local sources. The elevated Toluca Basin highland position aids dispersal on most days, while winter inversions create seasonal challenges and the Mexico City-Toluca metropolitan regional background influences the area throughout most of the year.

When is air pollution at its worst in San Felipe del Progreso?
San Felipe del Progreso usually sees its poorest air quality when traffic on the surrounding roads together with farming and agricultural processing coincide with periods when calm, stagnant conditions settle in the surrounding valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. The effect is strongest during the colder months, when inversions set in most often.
Are air quality levels in San Felipe del Progreso 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.
