San Miniato Basso owes much of its air quality variation to vehicle traffic and light industry across the plain, compounded by its position on the Arno river plain near Pisa. The surrounding Toscana terrain can either help disperse or trap these emissions depending on the weather, with active, breezy conditions generally bringing the clearest air.

When is air pollution at its worst in San Miniato Basso?
San Miniato Basso residents most often flag air quality concerns during olive and cypress pollen season and spells of vehicle traffic and light industry across the plain; the remaining months across Toscana tend to be considerably calmer and clearer.
Are air quality levels in San Miniato Basso 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.
