Pacatuba's air quality reflects the greater Fortaleza metropolitan area's southern suburban corridor in the Serra de Pacatuba hills, with vehicle emissions from the CE-060 and surrounding mixed residential and industrial character contributing local sources. Consistent Atlantic trade winds from the Ceará coast provide background ventilation, while the Pacatuba highland position at 255 metres provides marginally better dispersal than the flat coastal metropolitan plain and the growing metropolitan expansion drives increasing vehicle emissions.

When is air pollution at its worst in Pacatuba?
You're most likely to notice worse air in Pacatuba when native caatinga scrub and introduced urban trees pollen peaks, or due to vehicle emissions from the CE-060 and surrounding mixed residential and industrial character; a shift to wetter or windier weather typically brings noticeable relief.
Are air quality levels in Pacatuba 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.
