Teófilo Otoni's air quality reflects its position in the Mucuri river valley in the Minas Gerais northeastern border region, with vehicle emissions from the BR-116 and the surrounding gemstone mining, ceramics, and agribusiness operations contributing local sources in this major gemstone trading hub. The valley's topographic enclosure between the Espinhaço range foothills creates modest concentration of emissions under calm conditions, while dry season burning from surrounding Minas Gerais and Bahia Caatinga agricultural land contributes seasonal PM2.5 variation throughout the year.

When is air pollution at its worst in Teófilo Otoni?
The most noticeable dips in Teófilo Otoni's air quality come when eucalyptus and the Mucuri River corridor vegetation pollen peaks, or because of vehicle emissions from the BR-116 and the surrounding gemstone mining, ceramics, and agribusiness operations; things typically settle down again once the weather pattern shifts.
Are air quality levels in Teófilo Otoni 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.
