Crateús's air quality reflects the Ceará semi-arid Sertão interior in the Ibiapaba foothills, with vehicle emissions from the BR-020 and surrounding cattle, cotton, and agricultural operations contributing local sources. Drought conditions and Caatinga burning contribute seasonal PM10 and PM2.5 elevation, while the Ibiapaba highlands to the west create topographic variation and the semi-arid climate creates naturally dusty conditions during dry windy periods throughout the year.

When is air pollution at its worst in Crateús?
You're most likely to notice worse air in Crateús when native caatinga scrub and carnauba wax palm pollen peaks, or due to vehicle emissions from the BR-020 and surrounding cattle, cotton, and agricultural operations; a shift to wetter or windier weather typically brings noticeable relief.
Are air quality levels in Crateús 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.
