Garanhuns's air quality reflects its elevated position on the Pernambuco Agreste Meridional plateau at 896 metres, one of northeastern Brazil's highest urban centres, providing generally excellent background dispersal characteristics for a Brazilian city of its size. Vehicle emissions from the PE-145 and the surrounding dairy farming, coffee, and technology hub operations contribute modest local sources, while the elevated plateau position and consistent Atlantic trade wind influence at altitude generally maintain some of northeastern Brazil's best urban air quality readings.

When is air pollution at its worst in Garanhuns?
You're most likely to notice worse air in Garanhuns when eucalyptus and coffee plantation vegetation pollen peaks, or due to vehicle emissions from the PE-145 and the surrounding dairy farming, coffee, and technology hub operations; for the rest of the year, natural airflow keeps background levels low.
Are air quality levels in Garanhuns 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.
