Marituba's air quality reflects its position in the greater Belém metropolitan area in the Pará Amazon estuary, with vehicle emissions from the BR-316 and the surrounding mixed urban growth of this rapidly expanding Belém satellite municipality contributing local sources. Atlantic equatorial airflows provide general background ventilation, while dry season burning from surrounding Pará Amazon deforestation generates intense regional PM2.5 episodes between July and November that dominate the metropolitan air quality across the entire greater Belém corridor during the burning season.

When is air pollution at its worst in Marituba?

The most noticeable dips in Marituba's air quality come when secondary vegetation and introduced urban trees pollen peaks, or because of vehicle emissions from the BR-316 and the surrounding mixed urban growth of this rapidly expanding Belém; the rest of the calendar year is generally more forgiving for air quality.

Are air quality levels in Marituba 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.
