Araguaína's air quality faces severe seasonal challenges as a major Tocantins slaughterhouse and agribusiness hub at the gateway to the Amazon-Cerrado transition zone, with dry season burning from surrounding deforestation and cattle ranching generating intense PM2.5 episodes. Vehicle emissions from the BR-153 Belém-Brasília highway contribute year-round, while the flat Tocantins river plain's calm dry season conditions allow agricultural smoke to accumulate across the entire northern Tocantins region between June and October.

When is air pollution at its worst in Araguaína?
The most noticeable dips in Araguaína's air quality come when babaçu palm and pasture grasses pollen peaks, or because of dry season burning from surrounding deforestation and cattle ranching; things typically settle down again once the weather pattern shifts.
Are air quality levels in Araguaína 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.
