Estância's air quality reflects the Sergipe southeastern coastal zone, with consistent Atlantic trade winds providing reliable maritime ventilation along this historic colonial and petroleum extraction city. Vehicle emissions from the BR-101 and the Petrobras petroleum operations in the surrounding Sergipe-Alagoas basin contribute local sources, while the coastal position and consistent trade winds generally maintain moderate readings for a northeastern Brazilian coastal city throughout most of the year.

When is air pollution at its worst in Estância?

In Estância, reduced air quality is most noticeable when native Atlantic Forest remnants and restinga coastal scrub pollen peaks, and on days affected by vehicle emissions from the BR-101 and the Petrobras petroleum operations in the surrounding Sergipe-Alagoas basin; the picture usually improves again once the season turns.

Are air quality levels in Estância 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.
