Jacobina's air quality reflects the Bahia semi-arid Sertão at 390 metres in the Chapada Diamantina foothills, with vehicle emissions from the BR-324 and surrounding gold mining operations and agricultural activity contributing local sources. Mining dust from the Jacobina gold mine operations represents the most distinctive local PM10 source, while Caatinga burning contributes seasonal variation and the elevated position aids background dispersal compared to the semi-arid lowlands below.

Is air quality bad in Jacobina right now?
On 30 August 2026, overall air quality in Jacobina is very poor. AQI is the main air quality indicator at 100/100. Pollution peaks around 2:00 AM (PM2.5: 100/100).
Will air quality be worse tomorrow in Jacobina?
On 31 August 2026, air quality conditions in Jacobina will be similar to today, with AQI forecast at very poor at 100/100. Pollution peaks around 1:00 PM (PM2.5: 100/100).
When is air pollution at its worst in Jacobina?
Residents in Jacobina are most likely to notice reduced air quality when native caatinga scrub and eucalyptus pollen peaks, or due to vehicle emissions from the BR-324 and surrounding gold mining operations and agricultural activity; background levels usually settle back down once the season changes.
Are air quality levels in Jacobina 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.
