Quixadá's air quality reflects the Ceará Sertão interior at 206 metres near the iconic granite monolith inselbergs, with vehicle emissions from the CE-060 and surrounding cattle, cotton, and renewable energy operations contributing local sources. Drought conditions and Caatinga burning contribute seasonal PM10 elevation, while the semi-arid terrain generally allows reasonable dispersal and the inland position reduces the beneficial Atlantic trade wind coastal ventilation throughout the year.

When is air pollution at its worst in Quixadá?
Reduced air quality in Quixadá is most likely when native caatinga scrub and sparse drought-adapted trees pollen peaks, alongside periods of vehicle emissions from the CE-060 and surrounding cattle, cotton, and renewable energy operations; background levels usually settle back down once the season changes.
Are air quality levels in Quixadá 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.
