Very good!
ESA's Claus Zehner, Sentinel-5P mission manager, said, 'The decline in nitrogen dioxide emissions over the Po Valley in northern Italy is particularly evident.
'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.'
Similar changes in pollution levels were noted by NASA researcher Santiago Gasso when studying other data from Copernicus.
He said: 'In one month, there is a clear decrease of NO2 levels (a pollution marker) in northern Italy according to the satellite sensor.'
