Serrinha's air quality reflects the Bahia semi-arid Sisal region, with vehicle emissions from the BR-116 and surrounding sisal, cattle, and food processing operations contributing local sources in this major sisal producing hub. The elevated Bahia plateau position aids background dispersal, while dry season burning from surrounding Bahia agricultural and Caatinga land contributes seasonal PM2.5 variation and the sisal processing operations add distinctive dust and fibre PM10 throughout the year.

When is air pollution at its worst in Serrinha?
In Serrinha, reduced air quality is most noticeable when native caatinga scrub and sisal plantation vegetation pollen peaks, and on days affected by vehicle emissions from the BR-116 and surrounding sisal, cattle, and food processing operations; background levels usually settle back down once the season changes.
Are air quality levels in Serrinha 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.
