Juazeiro do Norte's air quality benefits from its elevated position on the Chapada do Araripe plateau at 430 metres in the Ceará semi-arid interior, with generally good background dispersal characteristics. Vehicle emissions from the BR-116 and the growing pilgrimage city's road network are the primary sources, while drought conditions and dry season burning from surrounding semi-arid Caatinga landscape contribute seasonal PM10 episodes across the broader Crajubar metropolitan area.

Is air quality bad in Juazeiro do Norte right now?
On 9 August 2026, overall air quality in Juazeiro do Norte is fair. AQI is the main air quality indicator at 23.8/100. Pollution peaks around 6:00 PM (PM2.5: 23.8/100).

When is air pollution at its worst in Juazeiro do Norte?
Air quality dips in Juazeiro do Norte mostly track fruit orchards and the elevated Chapada vegetation above pollen peaks and periods of vehicle emissions from the BR-116 and the growing pilgrimage city's road network; beyond that, the area's natural ventilation keeps air quality consistently favourable through the rest of the year.
Are air quality levels in Juazeiro do Norte 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.
