Cava de' Tirreni's air quality reflects the Metelliano river valley in the Campanian Apennines at 195 metres above Salerno, with vehicle traffic on the A3 motorway and surrounding manufacturing and urban operations contributing local sources. The surrounding Lattari and Picentini mountain massifs create significant topographic enclosure, while the Tyrrhenian sea breezes provide ventilation on westerly days and the Campanian regional background influences the broader valley air quality under prolonged anticyclonic conditions throughout the year.

When is air pollution at its worst in Cava de’ Tirreni?
Air quality dips in Cava de’ Tirreni mostly track oak and linden pollen peaks and periods of vehicle traffic on the A3 motorway and local manufacturing and urban operations; background levels usually settle back down once the season changes.
Are air quality levels in Cava de’ Tirreni 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.
