desymbol: Satellite Images Show How Pollution Has Decreased In Italy After The Coronavirus Quarantine Started

Most of us are likely feeling the effects of the Coronavirus outbreak that is sweeping across the world, be it nurses, doctors, civilians or entire governments. The areas of quarantine are increasing just as the number of infected rises and it is very hard to have a positive outlook on the future when no one has any answers in regards to it. Well, scientists finally are reporting a positive change, albeit it might not be what we might expect.

According to the European Space Agency (ESA), as well as a handful of independent researchers, the nitrogen dioxide emissions have significantly decreased over Italy following the lockdown caused by the spread of COVID-19. The Copernicus Sentinel-5P satellite detected a decline in NO2 emissions, signaling the decrease in air pollution, with the most significant change being observed in the northern part of the country.

“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.”

Santiago Gassó, a research associate at NASA, took to Twitter to report on the results of the satellite sensor. He also explained that while fluctuating NO2 emissions are completely normal considering that they differ under such factors as the day of the week, this observed change was definitely significant.
