Estância Velha's air quality reflects the greater Porto Alegre metropolitan area's northern Sinos river valley, with vehicle emissions from the RS-239 and the surrounding footwear and light manufacturing industry generating distinctive leather and chemical emissions alongside primary vehicle sources. The Sinos valley's topographic enclosure concentrates industrial emissions under calm conditions, while the leather industry's VOC profile represents the region's most distinctive air quality characteristic throughout the year.

When is air pollution at its worst in Estância Velha?
You're most likely to notice worse air in Estância Velha when native Atlantic Forest remnants and introduced urban trees pollen peaks, or due to vehicle emissions from the RS-239 and the surrounding footwear and light manufacturing industry; the clearest air tends to follow a change in wind direction or rainfall here.
Are air quality levels in Estância Velha 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.
