Worst air pollution Governador Valadares, today and tomorrow

On 9 August 2026, overall air quality in Governador Valadares is good. AQI is the main air quality indicator at 19.6/100. Pollution peaks around 10:00 PM (O3: 19.6/100).

On 10 August 2026, air quality conditions in Governador Valadares will be similar to today, with AQI forecast at good at 19.5/100. Pollution peaks around 8:00 AM (O3: 19.5/100).

In Governador Valadares, reduced air quality is most noticeable when eucalyptus and the Doce River corridor vegetation pollen peaks, and on days affected by vehicle emissions from the BR-116 and the surrounding steel and mining activity in the Vale do; conditions usually ease once the wet season or windier weather returns.

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.

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.
