Petrolina's air quality reflects its position in the São Francisco River valley in the Pernambuco-Bahia semi-arid border region, with vehicle emissions from the BR-407 and the surrounding irrigated fruit farming and wine production corridor contributing local sources. Drought conditions and dry season burning from the Caatinga landscape contribute elevated PM10, while the São Francisco valley's channelling of northerly and southerly winds provides generally reasonable ventilation across this major semi-arid agricultural and energy hub.

When is air pollution at its worst in Petrolina?
People in Petrolina tend to notice reduced air quality when native caatinga scrub and irrigated fruit orchards pollen peaks, or because of vehicle emissions from the BR-407 and the surrounding irrigated fruit farming and wine production corridor; the rest of the calendar year is generally more forgiving for air quality.
Are air quality levels in Petrolina 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.
