Reggio Emilia's air quality faces the Po Valley's notorious flat basin topography, with the surrounding Alpine and Apennine ranges creating near-complete topographic enclosure that traps vehicle and agri-food industry emissions under winter anticyclones. Vehicle traffic on the A1 motorway and the surrounding Emilian agri-food manufacturing corridor — including the Parmigiano-Reggiano cheese production operations — generate elevated NOₓ and organic aerosols, while the flat Po plain's persistent winter fog inversions trap all emission sources for extended periods.

When is air pollution at its worst in Reggio Emilia?
In Reggio Emilia, reduced air quality is most noticeable when oak and poplar pollen peaks, and on days affected by the nearby Alpine and Apennine ranges; conditions generally improve once the season shifts and rainfall or stronger winds return.
Are air quality levels in Reggio Emilia 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.
