As Coronavirus is spreading and causing thousands of innocent people to die, it is extremely hard to have a positive outlook on the future that we currently have no idea what it has in store for us. However, just like every bad situation, this one has a positive side too.
According to the European Space Agency (ESA) and other researchers, nitrogen dioxide pollution over Italy, especially the northern part, has fallen drastically after the lockdown.
“The decline in nitrogen dioxide emissions over the Po Valley in northern Italy is particularly evident,” Claus Zehner, ESA’s Copernicus Sentinel-5P mission manager reported. “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.”
“Copernicus Sentinel-5P Tropomi is the most accurate instrument today that measures air pollution from space. These measurements, globally available thanks to the free and open data policy, provide crucial information for citizens and decision-makers,” said Josef Aschbacher, ESA’s Director of Earth Observation Programmes.

The data presented by the European Space Agency (ESA) shows the same tendency.
Some Italians have also reported that the surrounding environment has changed too.
