Esmeraldas' air quality in Brazil reflects the greater Belo Horizonte metropolitan area's northwestern ring, with vehicle emissions from the MG-010 and surrounding mixed industrial and residential character contributing elevated PM2.5. The enclosed Belo Horizonte basin's poor dispersal characteristics affect the entire northern and western metropolitan corridors, particularly during the dry winter months when Minas Gerais highland inversions concentrate emissions throughout the year.

Is air quality bad in Esmeraldas right now?
On 9 August 2026, overall air quality in Esmeraldas is fair. PM10 is the main pollutant at 25.7/100. Pollution peaks around 4:00 PM (PM2.5: 43.6/100).

When is air pollution at its worst in Esmeraldas?
In Esmeraldas, reduced air quality is most noticeable when eucalyptus and introduced urban trees pollen peaks, and on days affected by vehicle emissions from the MG-010 and surrounding mixed industrial and residential character; the clearest air tends to follow a change in wind direction or rainfall here.
Are air quality levels in Esmeraldas 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.
