Santa Cruz de la Sierra's air quality reflects the flat Bolivian lowland Gran Chaco plain at 416 metres, with vehicle traffic on surrounding roads and the agribusiness, vehicle density, and industrial corridor generating elevated PM2.5. Consistent Chaco and Amazonian breezes provide reasonable dispersal, while dry season agricultural burning from surrounding Bolivian and Brazilian deforestation generates severe PM2.5 episodes and Santa Cruz generally maintains moderate to elevated Bolivian lowland capital readings during burning season.

When is air pollution at its worst in Santa Cruz de la Sierra?
The biggest local contributors to pollution in Santa Cruz de la Sierra are traffic on the surrounding roads together with agricultural burning, particularly once dry spells bring strong winds. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. These episodes tend to cluster in spring and autumn.
Are air quality levels in Santa Cruz de la Sierra 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.
