Nuevo Casas Grandes's air quality reflects the flat Chihuahuan Desert Casas Grandes River valley at 1,469 metres near the famous Paquimé archaeological site, with vehicle traffic on surrounding roads and the agricultural, pottery, and services corridor contributing modest local sources. Windblown Chihuahuan Desert dust contributes elevated PM10, while the flat semi-arid terrain allows reasonable dispersal and Nuevo Casas Grandes generally maintains moderate to good northern Mexican Chihuahuan Desert valley readings throughout most of the year.

When is air pollution at its worst in Nuevo Casas Grandes?
The biggest local contributors to pollution in Nuevo Casas Grandes are road traffic together with agricultural activity, particularly once dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. This is most noticeable during spring and autumn wind events.
Are air quality levels in Nuevo Casas Grandes 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.
