Caserta's air quality faces the Campanian plain's enclosed volcanic basin position, with vehicle traffic on the A1 motorway and surrounding manufacturing and urban development generating elevated NOₓ and PM2.5. The surrounding Apennine hills and the Caserta plain's semi-enclosed geometry create topographic concentration under calm anticyclonic conditions, while the Royal Palace gardens provide a limited local green buffer within this major Campanian metropolitan city.

Is air quality bad in Caserta right now?
On 9 August 2026, overall air quality in Caserta is medium. AQI is the main air quality indicator at 45.1/100. Pollution peaks around 6:00 PM (O3: 45.1/100).

When is air pollution at its worst in Caserta?
Reduced air quality in Caserta is most likely when local tree and grass pollen peaks, alongside periods of vehicle traffic on the A1 motorway and neighbouring manufacturing and urban development; background levels usually settle back down once the season changes.
Are air quality levels in Caserta 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.
