Marechal Cândido Rondon's air quality reflects the Paraná western plateau at 420 metres near the Argentine border, with vehicle emissions from the BR-467 and surrounding soybean, corn, and cattle agribusiness operations contributing local sources. The flat western Paraná plateau generally provides reasonable wind dispersal, while dry season burning from surrounding Paraná and Argentinian cross-border agricultural land contributes seasonal PM2.5 variation throughout the year.

When is air pollution at its worst in Marechal Cândido Rondon?
Reduced air quality in Marechal Cândido Rondon is most likely when native Atlantic Forest remnants and soybean farmland pollen peaks, alongside periods of vehicle emissions from the BR-467 and surrounding soybean, corn, and cattle agribusiness operations; wind and rain both help clear the air fairly quickly here.
Are air quality levels in Marechal Cândido Rondon 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.
