Viçosa do Ceará's air quality reflects the Ceará highland at 900 metres on the Ibiapaba plateau near the Piauí border, with vehicle emissions from the CE-187 and surrounding agricultural and ecotourism operations contributing modest local sources. The elevated plateau position provides naturally good background dispersal, while consistent Atlantic trade wind influence at altitude generally maintains cleaner conditions than the lowland semi-arid Sertão below and the surrounding Atlantic Forest-Cerrado ecotone provides a relatively clean environmental backdrop.

When is air pollution at its worst in Viçosa do Ceará?
The most noticeable dips in Viçosa do Ceará's air quality come when native cerrado trees and Atlantic Forest remnants on the serra slopes pollen peaks, or because of vehicle emissions from the CE-187 and surrounding agricultural and ecotourism operations; conditions usually ease once the wet season or windier weather returns.
Are air quality levels in Viçosa do Ceará 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.
