Rome's Trastevere records moderate to elevated air quality for central Rome, with the neighbourhood's popularity generating dense tourist and scooter traffic through its narrow medieval streets that limits pollutant dispersal. Evening traffic peaks can produce the highest local readings, while the Gianicolo hill above provides occasional cleaner air drainage.

When is air pollution at its worst in Trastevere?
Trastevere residents notice reduced air quality mainly when riverside pollen peaks, and during spells of the neighbourhood's popularity; wind and rain both help clear the air fairly quickly here.
Are air quality levels in Trastevere 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.
