Cascavel's air quality in Ceará reflects the northeastern Ceará semi-arid interior, with vehicle emissions from the CE-085 and surrounding agricultural and light industrial operations contributing local sources. Atlantic trade winds from the Fortaleza metropolitan coast provide reasonable regional ventilation, while drought conditions and Caatinga burning contribute seasonal PM10 elevation and the inland position reduces the direct coastal trade wind benefit compared to oceanside Ceará municipalities throughout the dry season.

When is air pollution at its worst in Cascavel, Ceara?

Residents in Cascavel are most likely to notice reduced air quality when native caatinga scrub and restinga coastal dune vegetation pollen peaks, or due to vehicle emissions from the CE-085 and surrounding agricultural and light industrial operations; the rest of the calendar year is generally more forgiving for air quality.

Are air quality levels in Cascavel, Ceara 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.
