Santo Amaro's air quality reflects its position in the greater Salvador metropolitan northern corridor in Bahia, with vehicle emissions from the BA-093 and surrounding mixed agricultural and residential character contributing local sources. Atlantic trade winds from the Bahia Recôncavo coast provide general background ventilation, while the Recôncavo's tobacco, sugarcane, and agricultural landscape contributes organic aerosols during the harvest season and the growing metropolitan expansion drives increasing vehicle emissions.

When is air pollution at its worst in Santo Amaro?
In Santo Amaro, reduced air quality is most noticeable when native Atlantic Forest remnants and eucalyptus pollen peaks, and on days affected by vehicle emissions from the BA-093 and surrounding mixed agricultural and residential character; the picture usually improves again once the season turns.
Are air quality levels in Santo Amaro 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.
