Buíque's air quality reflects the Pernambuco semi-arid Sertão interior at 770 metres near the Vale do Catimbau National Park, with vehicle emissions from the PE-270 and surrounding cattle, sisal, and subsistence farming contributing local sources. The Borborema plateau creates topographic variation, while drought conditions and Caatinga burning contribute seasonal PM10 elevation throughout the dry season and the elevated plateau position aids dispersal compared to the lowland semi-arid regions throughout the year.

Is air quality bad in Buíque right now?
On 9 August 2026, overall air quality in Buíque is good. AQI is the main air quality indicator at 19.9/100. Pollution peaks around 12:00 AM (O3: 19.9/100).

When is air pollution at its worst in Buíque?
Air quality dips in Buíque mostly track native caatinga scrub and endemic Catimbau plateau vegetation pollen peaks and periods of vehicle emissions from the PE-270 and surrounding cattle, sisal, and subsistence farming; wind and rain both help clear the air fairly quickly here.
Are air quality levels in Buíque 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.
