In the late days of March, scientists at the Copernicus Atmospheric Monitoring Service saw a large space over the Arctic region. So far, they had not had such a large cleft in the atmosphere.
Soon it turned into a big hole. They had not yet been confronted with such a large hole in the northern hemisphere. Its size was equal to Greenland and spread the surface of the polar icecap.
On April 23, good news came. In a tweet, CAMS reported that the unprecedented hole in the Ozone layer in the Northern Hemisphere in March of 2020 this year has been closed.
Why is Ozone so important?
In fact, the ozone layer provides the Earth with the necessary protection from the sun’s harmful rays. Most of the earth’s ozone is present in the upper level of its atmosphere( stratosphere).
The ozone layer at an altitude of 10-40 km from the ground is very helpful in protecting the Earth from ultraviolet radiation.
