Rolim de Moura's air quality faces severe seasonal challenges as a Rondônia agricultural frontier city, with dry season burning from surrounding deforestation generating intense PM2.5 episodes between June and October. Vehicle emissions from the BR-421 contribute year-round, while the flat western Rondônia plateau's calm dry season conditions allow agricultural and deforestation smoke to accumulate extensively and the frontier agricultural character makes burning the dominant seasonal air quality influence throughout the region.

When is air pollution at its worst in Rolim de Moura?
Reduced air quality in Rolim de Moura is most likely when pasture grasses and secondary vegetation pollen peaks, alongside periods of dry season burning from surrounding deforestation; things typically settle down again once the weather pattern shifts.
Are air quality levels in Rolim de Moura 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.
