Marino's air quality reflects its position in the Alban Hills southeast of Rome, with vehicle traffic on the Via Appia and Rome commuter routes contributing the main local sources through the year. Weather patterns typical of Lazio shape how quickly pollutants clear, with conditions generally improving whenever winds pick up or rain moves through, while calmer, high-pressure spells tend to let local emissions accumulate for longer than elsewhere in the region.

Are air quality levels in Marino 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.
