Paulínia's air quality faces significant industrial challenges as the location of the Replan petroleum refinery, Brazil's largest oil refinery, generating elevated SO₂, benzene, and industrial PM2.5 alongside the surrounding Polo Industrial de Paulínia chemical complex. The Campinas basin's topographic setting affects dispersal, while the refinery's extraordinary scale makes Paulínia one of São Paulo state's most distinctively industrial-defined urban air quality environments.

When is air pollution at its worst in Paulínia?
People in Paulínia tend to notice reduced air quality when sugarcane vegetation and introduced urban trees pollen peaks, or because of the Campinas basin's topographic setting affects dispersal, while the refinery's extraordinary scale makes Paulínia; the picture usually improves again once the season turns.
Are air quality levels in Paulínia 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.
