Ponta Porã's air quality reflects the Mato Grosso do Sul southern plateau at the Brazil-Paraguay border, with vehicle emissions from the BR-463 and cross-border commercial traffic from Pedro Juan Caballero generating elevated vehicle NOₓ. The flat highland plateau generally allows reasonable wind dispersal, while dry season burning from surrounding Paraguayan and Brazilian Cerrado agricultural land contributes seasonal PM2.5 variation throughout the year.

When is air pollution at its worst in Ponta Porã?
The most noticeable dips in Ponta Porã's air quality come when native cerrado remnants and introduced urban trees pollen peaks, or because of vehicle emissions from the BR-463 and cross-border commercial traffic from Pedro Juan Caballero; background levels usually settle back down once the season changes.
Are air quality levels in Ponta Porã 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.
