Apatzingan de la Constitucion's air quality reflects the Michoacán Tierra Caliente hot country's Tepalcatepec River valley at 300 metres, with vehicle traffic on surrounding roads and the lime, mango, and agricultural corridor contributing local sources. The surrounding Sierra Madre del Sur creates topographic variation, while the hot tropical climate's convective rain provides periodic atmospheric cleansing and Apatzingán generally maintains moderate to good Mexican hot country agricultural valley readings throughout most of the year.

When is air pollution at its worst in Apatzingan de la Constitucion?
In Apatzingan de la Constitucion, traffic on the surrounding roads and crop farming are the main local sources, with conditions worsening when winds are light and dispersion is poor. Day-to-day conditions here depend heavily on the weather. Background emissions and local weather both play a role in day-to-day changes.
Are air quality levels in Apatzingan de la Constitucion 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.
