Air pollution during lockdown in India, lowest level in 20 years

India has been facing the worst air pollution challenge for many years and especially in the capital of india New Delhi, air pollution reached its worst level in history last winter.

However, according to a report by the US space agency NASA, the nationwide lockdown due to the coronavirus in India has brought the pollution to its lowest level in 20 years.

NASA has released a list of maps with images from March 31 to April 1, 2016, as well as 2020 images from the same period.


"We expected to see a change in the atmosphere during the lockdown, but I have never seen such a reduction in pollution this part of the year," said Pawan Gupta, a scientist at the University Space Research Association.

This report examines air pollution through aerosol optical depth, in which air pollution is measured by the degree to which light is being emitted from these air particles.

In northern India, the rate was extremely low in early April and has reached a 20-year low, the report said.

Ground-level surveillance agencies in India also say that air pollution has been significantly reduced during the lockdown.

It should be noted that the lockdown has been going on in India for five weeks in view of the global threat of Coronavirus.

Since India announced a nationwide lockdown on March 25, all industries and transport, including construction activities, have been shut down across the country.

 

Not only in India, but thanks to the lockdown, the atmosphere around the world has clearly improved.
