Iguala de la Independencia's air quality reflects the Guerrero Balsas River valley's enclosed basin at 733 metres surrounded by the Sierra Madre del Sur, with vehicle traffic on surrounding roads and the government, services, and agricultural corridor contributing local sources. The valley's topographic enclosure creates concentration under winter inversions, while the surrounding mountain ranges create significant topographic enclosure and Iguala generally maintains moderate to elevated Mexican southern highland valley readings throughout most of the year.

When is air pollution at its worst in Iguala de la Independencia?
Air quality in Iguala de la Independencia tends to be worse when road traffic along with crop farming build up and the surrounding valley traps air close to the ground. Topographic enclosure in the valley lets pollution accumulate rather than clear out. This tends to happen most in winter, when inversions are most common.
Are air quality levels in Iguala de la Independencia 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.
