Bacabal's air quality reflects the Maranhão interior, with vehicle emissions from the BR-316 and surrounding babaçu palm, agricultural, and light manufacturing operations contributing local sources. Dry season burning from surrounding Maranhão Cerrado-Caatinga agricultural land contributes seasonal PM2.5 variation, while the flat Maranhão interior generally allows reasonable wind dispersal on most days throughout the burning season.

When is air pollution at its worst in Bacabal?
People in Bacabal tend to notice reduced air quality when babaçu palm and secondary vegetation pollen peaks, or because of vehicle emissions from the BR-316 and surrounding babaçu palm, agricultural, and light manufacturing operations; conditions generally improve once the season shifts and rainfall or stronger winds return.
Are air quality levels in Bacabal 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.
