Ciudad López Mateos's air quality reflects Mexico City's northwestern metropolitan corridor at 2,255 metres in the Valley of Mexico, with vehicle traffic on surrounding roads and the manufacturing, residential, and commercial corridor generating elevated PM2.5 under persistent valley inversions. The enclosed Valley of Mexico's near-complete topographic trapping compounds emissions extensively, while the residential and industrial character maintains moderate to elevated Mexico City northwestern metropolitan corridor readings throughout most of the year.

When is air pollution at its worst in Ciudad López Mateos?
The biggest local contributors to pollution in Ciudad López Mateos are road traffic and manufacturing activity, particularly once calm, stagnant conditions settle in the surrounding valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher.
Are air quality levels in Ciudad López Mateos 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.
