Los Reyes de Salgado's air quality reflects the Michoacán Tierra Caliente foothills at 1,237 metres, with vehicle traffic on surrounding roads and the avocado, berry, and agricultural corridor contributing local sources. The surrounding Sierra Madre del Sur creates topographic variation, while the tropical highland climate's frequent rain provides effective atmospheric cleansing and Los Reyes generally maintains moderate to good Mexican western Michoacán avocado highland readings throughout most of the year.

When is air pollution at its worst in Los Reyes de Salgado?
The biggest local contributors to pollution in Los Reyes de Salgado are vehicle traffic together with agricultural activity, particularly once weather conditions turn unfavourable. Background emissions and local weather both shape how conditions change from day to day. Local weather patterns add further day-to-day variation.
Are air quality levels in Los Reyes de Salgado 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.
