Caruaru's air quality reflects its position on the Borborema Plateau in the Pernambuco semi-arid interior at 554 metres, with vehicle emissions from the BR-232 and the leather and textile manufacturing industry contributing local sources. The elevated semi-arid plateau position generally aids background dispersal, while drought conditions and dry season burning from the surrounding semi-arid Caatinga scrubland contribute elevated PM10 and PM2.5 episodes across the broader Agreste Pernambucano region.

When is air pollution at its worst in Caruaru?
The most noticeable dips in Caruaru's air quality come when native caatinga scrub and Atlantic Forest remnants pollen peaks, or because of vehicle emissions from the BR-232 and the leather and textile manufacturing industry; conditions generally improve once the season shifts and rainfall or stronger winds return.
Are air quality levels in Caruaru 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.
