Macaíba's air quality reflects the Rio Grande do Norte metropolitan area adjacent to Natal, with vehicle emissions from the BR-304 and surrounding industrial and residential growth contributing local sources in this major Natal satellite. Atlantic trade winds from the Rio Grande do Norte coast provide general background maritime ventilation, while the growing Natal metropolitan expansion and the industrial character of the Macaíba logistics corridor drive increasing local emissions throughout the year.

When is air pollution at its worst in Macaíba?
Residents in Macaíba are most likely to notice reduced air quality when native caatinga scrub and introduced urban trees pollen peaks, or due to vehicle emissions from the BR-304 and surrounding industrial and residential growth; a change of season or a spell of wind usually clears things up again.
Are air quality levels in Macaíba 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.
