Fog and smog: it is already autumn in the skies of the Po Valley, as shown by the image acquired on 5 October by the Sentinel-3 satellite of the Copernicus Earth observation program, of the European Space Agency (ESA) and the European Commission.
"The current high atmospheric pressure causes stagnation of the air masses, the accumulation of humidity and smog in the lower layers of the atmosphere and consequently a deterioration of the local air quality", explain the experts on the Copernicus site.
Complementing the Copernicus satellite data, the Copernicus Atmosphere Monitoring Service (CAMS) detects and predicts air quality on a global scale by assessing and predicting the concentration of air pollutants, as well as their transport and dispersion.
