San Andrés Tuxtla's air quality reflects the Veracruz volcanic highland's Tuxtla massif position at 287 metres, with vehicle traffic on surrounding roads and the tobacco, citrus, and agricultural corridor contributing local sources. The surrounding Sierra de los Tuxtlas volcanic rises create topographic variation, while the tropical climate's frequent rain provides effective atmospheric cleansing and San Andrés generally maintains moderate southern Veracruz volcanic highland readings throughout most of the year.

When is air pollution at its worst in San Andrés Tuxtla?
Pollution in San Andrés Tuxtla typically rises when traffic on the surrounding roads together with farming and agricultural processing combine, especially once weather conditions turn unfavourable. Day-to-day conditions here depend heavily on the weather. Local weather patterns add further day-to-day variation.
Are air quality levels in San Andrés Tuxtla 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.
