Santa Cruz do Sul's air quality reflects its position in the Rio Grande do Sul tobacco farming plateau at 148 metres, with the British American Tobacco and Philip Morris international tobacco processing operations generating distinctive tobacco drying and curing emissions alongside vehicle traffic on the RS-287. The tobacco industry's seasonal curing operations between March and June represent the most distinctive local air quality contribution, while dry season burning from surrounding Rio Grande do Sul agricultural land adds seasonal PM2.5 variation throughout the year.

When is air pollution at its worst in Santa Cruz do Sul?
Santa Cruz do Sul residents notice reduced air quality mainly when eucalyptus and tobacco farmland pollen peaks, and during spells of the British American Tobacco and Philip Morris international tobacco processing operations; the rest of the year typically brings clearer, more consistent conditions.
Are air quality levels in Santa Cruz do Sul 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.
