Palmas' air quality faces severe seasonal challenges as the capital of Tocantins at the heart of the Central Brazilian Cerrado, with dry season burning from surrounding agricultural deforestation generating intense PM2.5 episodes between June and October that routinely produce some of Brazil's highest seasonal readings. Vehicle emissions from the planned city's road network contribute year-round, while the flat Tocantins river plain generally provides reasonable ventilation during the wet season.

When is air pollution at its worst in Palmas?
Residents in Palmas are most likely to notice reduced air quality when native cerrado trees and eucalyptus pollen peaks, or due to dry season burning from surrounding agricultural deforestation; things typically settle down again once the weather pattern shifts.
Are air quality levels in Palmas 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.
