Ribeira do Pombal's air quality reflects the Bahia semi-arid interior in the Itapicuru river basin, with vehicle emissions from the BR-116 and surrounding sisal, cattle, and agricultural operations contributing local sources. The elevated Bahia plateau position aids background dispersal, while dry season burning from surrounding Caatinga agricultural land contributes seasonal PM2.5 variation and the sisal processing operations add distinctive fibre and dust PM10 as the most locally distinctive air quality contribution throughout the year.

When is air pollution at its worst in Ribeira do Pombal?
Reduced air quality in Ribeira do Pombal is most likely when native caatinga scrub and mandacaru cactus pollen peaks, alongside periods of vehicle emissions from the BR-116 and surrounding sisal, cattle, and agricultural operations; a shift to wetter or windier weather typically brings noticeable relief.
Are air quality levels in Ribeira do Pombal 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.
