Coronavirus: des images d’un satellite montrent la chute de la pollution en Italie du Nord Les quatre images ont été prises entre le 14 février et le 8 mars. The average concentrations of NO2 for the past four weeks have been at least 24% lower than four weeks earlier this year. Satellite images show drop in dangerous greenhouse gases following lockdownThe images are another striking example of how the pandemic has cut “Although there could be slight variations in the data due to cloud cover and changing weather, we are very confident that the reduction in emissions that we can see coincides with the lockdown in Italy causing less traffic and industrial activities,” said Claus Zehner, who manages the Copernicus Sentinel-5P, the satellite which took the photos over the Po Valley region.
