Janaúba's air quality reflects the northern Minas Gerais semi-arid Sertão at 516 metres in the upper São Francisco valley, with vehicle emissions from the BR-251 and surrounding irrigated fruit farming, cattle, and light manufacturing contributing local sources. The São Francisco valley provides reasonable wind dispersal corridors, while drought conditions and Caatinga burning contribute seasonal PM10 elevation across the semi-arid northern Minas Gerais region throughout the dry season.

Is air quality bad in Janaúba right now?
On 9 August 2026, overall air quality in Janaúba is poor. AQI is the main air quality indicator at 65.8/100. Pollution peaks around 4:00 PM (PM2.5: 65.8/100).
Will air quality be worse tomorrow in Janaúba?
On 10 August 2026, air quality conditions in Janaúba will be similar to today, with AQI forecast at poor at 67.9/100. Pollution peaks around 4:00 AM (PM2.5: 67.9/100).
When is air pollution at its worst in Janaúba?
The most noticeable dips in Janaúba's air quality come when native caatinga scrub and sparse drought-adapted trees pollen peaks, or because of vehicle emissions from the BR-251 and surrounding irrigated fruit farming, cattle, and light manufacturing; wind and rain both help clear the air fairly quickly here.
Are air quality levels in Janaúba 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.
