Pachuca's air quality reflects the Hidalgo plateau's enclosed Pachuca valley at 2,426 metres surrounded by the Sierra de las Navajas, with vehicle traffic on surrounding roads and the government, mining legacy, and services corridor contributing local sources. The valley's topographic enclosure and the extreme altitude amplify ozone formation, while winter inversions create seasonal challenges and Pachuca generally maintains moderate to elevated Mexican highland valley readings throughout most of the year.

When is air pollution at its worst in Pachuca?
The biggest local contributors to pollution in Pachuca are traffic on the surrounding roads as well as quarrying activity, particularly once temperature inversions set in over the valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. Heat and sunlight combine with emissions to form ozone at ground level.
Are air quality levels in Pachuca 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.
