Asunción's air quality reflects the Paraguay River valley's flat topography providing reasonable wind dispersal, with vehicle emissions from the dense central street network the primary local source. Dry season burning from surrounding Chaco agricultural land contributes seasonal PM2.5, while the open Pampas airflows generally prevent the most severe pollution accumulation seen in more topographically enclosed South American capitals.

When is air pollution at its worst in Asunción?
Air quality dips in Asunción mostly track introduced urban boulevard trees native forest remnants and introduced urban boulevard trees pollen peaks and periods of neighbouring Chaco agricultural land; a shift to wetter or windier weather typically brings noticeable relief.
Are air quality levels in Asunción 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.
