Worst air pollution Via Appia Antica - Rome, today and tomorrow

On 9 August 2026, overall air quality in Via Appia Antica is medium. AQI is the main air quality indicator at 47.7/100. Pollution peaks around 2:00 PM (O3: 47.7/100).

On 10 August 2026, air quality conditions in Via Appia Antica will be worse than today, with PM1 forecast at fair at 20.4/100. Pollution peaks around 3:00 PM (O3: 55.3/100).

In Via Appia Antica, reduced air quality is most noticeable when local tree and grass pollen peaks, and on days affected by proximity to the Castelli Romani hills supports cleaner baseline conditions than most of Rome's; conditions generally improve once the season shifts and rainfall or stronger winds return.

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.

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.
