While Italy is under lockdown, satellite images show drastic drop in pollution during the coronavirus quarantine.

According to the European Space Agency (ESA), nitrogen dioxide emission has reduced significantly after the lockdown.

The Copernicus Sentinel-5P satellite detected the decrease in air pollution. Claus Zehner, ESA’s Copernicus 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.

In these graphs below, you can see the gradual decerease in NO2 pollution starting from 14th February:

Naturally, the streets are also empty and clean since no one is stepping out. Even canals in Venice have become crystal clear, all thanks to reduced traffic.

In Italy, over 1,809 have lost their lives due to coronavirus and more than 24,747 positive cases have been reported, till now.
