Rio Bonito's air quality reflects the Rio de Janeiro state Serrana interior at 64 metres, with vehicle emissions from the RJ-114 and surrounding agricultural and light manufacturing contributing local sources. The surrounding Serrana highlands and the Rio Bonito plateau create topographic variation, while Atlantic sea breezes from the Niterói coast provide periodic ventilation relief and the relatively rural character and distance from Rio de Janeiro's industrial core generally maintains moderate conditions throughout the year.

When is air pollution at its worst in Rio Bonito?
In Rio Bonito, reduced air quality is most noticeable when native Atlantic Forest remnants and eucalyptus pollen peaks, and on days affected by vehicle emissions from the RJ-114 and surrounding agricultural and light manufacturing; the clearest air tends to follow a change in wind direction or rainfall here.
Are air quality levels in Rio Bonito 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.
