Taxco de Alarcón's air quality reflects the Guerrero Sierra Madre del Sur's deeply enclosed Atepec River gorge at 1,660 metres surrounded by the dramatic colonial silver mining hillsides, with vehicle traffic on surrounding roads and the silver jewelry manufacturing, tourism, and services corridor contributing elevated silver processing emissions alongside primary vehicle sources. The gorge's near-complete topographic enclosure creates severe concentration under inversions, while the silver jewelry industry's distinctive metal aerosols represent Taxco's most locally unique air quality contribution.

When is air pollution at its worst in Taxco de Alarcón?
Air quality in Taxco de Alarcón tends to be worse when traffic on the surrounding roads, quarrying activity, and textile and manufacturing operations build up and dry spells bring strong winds. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. This is most noticeable during spring and autumn wind events.
Are air quality levels in Taxco de Alarcón 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
