Cunduacán's air quality reflects the flat Tabasco tropical coastal plain's PEMEX oil production position, with vehicle traffic on surrounding roads and the oil extraction, cacao, and agricultural corridor contributing local sources. Gulf of Mexico trade winds and the tropical climate's frequent convective rain provide ventilation and atmospheric cleansing, while the oil production operations add distinctive hydrocarbon emissions and Cunduacán generally maintains moderate southern Mexican tropical oil corridor readings throughout most of the year.

When is air pollution at its worst in Cunduacán?
The biggest local contributors to pollution in Cunduacán are traffic on the surrounding roads, steel, cement, and chemical production, and agricultural activity, particularly once maritime winds die down. Sea breezes typically keep conditions in check, except during still weather. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Cunduacán 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.
