Agua Prieta's air quality reflects the flat Sonoran Desert Arizona-Sonora border position adjacent to Douglas Arizona, with vehicle traffic on surrounding roads and the maquiladora manufacturing and border crossing corridor generating elevated vehicle and industrial emissions. Windblown Sonoran Desert dust contributes elevated PM10, while the flat desert terrain allows reasonable dispersal and Agua Prieta generally maintains moderate to good northwestern Mexican Sonoran Desert border city readings throughout most of the year.

When is air pollution at its worst in Agua Prieta?
Agua Prieta usually sees its poorest air quality when traffic on the surrounding roads together with textile and manufacturing operations coincide with periods when dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. Such events are most common in the drier shoulder seasons.
Are air quality levels in Agua Prieta 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.
