Várzea Paulista's air quality reflects the Jundiaí metropolitan corridor of São Paulo state, with vehicle emissions from the SP-332 and surrounding industrial and residential character contributing elevated PM2.5 and NOₓ. The São Paulo metropolitan regional dispersal characteristics influence the entire Jundiaí corridor, while the Serra do Japi provides a forested backdrop with limited direct ventilation benefit for the densely settled valley below.

When is air pollution at its worst in Várzea Paulista?

You're most likely to notice worse air in Várzea Paulista when eucalyptus and native Atlantic Forest remnants pollen peaks, or due to vehicle emissions from the SP-332 and surrounding industrial and residential character; wind and rain both help clear the air fairly quickly here.

Are air quality levels in Várzea Paulista 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.
