La Peña in Mexico reflects the greater Mexico City metropolitan area's northwestern suburban corridor in the Valley of Mexico, with vehicle traffic on surrounding roads and the residential and light industrial character contributing local sources under the valley's persistent inversions. The enclosed Valley of Mexico's near-complete topographic trapping compounds emissions extensively and La Peña generally maintains moderate to elevated Mexico City metropolitan readings throughout most of the year.

When is air pollution at its worst in La Peña?
The biggest local contributor to pollution in La Peña is road traffic, 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 La Peña 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.
