Air quality in Comiso is shaped mainly by agricultural activity and vehicle traffic across the plain, against a backdrop of the Sicilia landscape on inland Sicily's agricultural plain. Ventilation varies with the terrain, and conditions are typically at their best when weather systems move through more actively, while extended dry, calm periods tend to coincide with the town's least favourable air quality readings.

When is air pollution at its worst in Comiso?
Comiso residents most often flag air quality concerns during oak and plane pollen season and spells of agricultural activity and vehicle traffic across the plain; the remaining months across Sicilia tend to be considerably calmer and clearer.
Are air quality levels in Comiso 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.
