Scientists have revealed that the hole observed in the ozone layer over the Arctic last month has been healed.
The Copernicus Atmosphere Monitoring Service (CAMS) tweeted about the development. The unprecedented #OzoneHole 2020 Northern Hemisphere has come to an end. The #PolarVortex division, which allows #ozone-rich air in the Arctic, closely coinciding with last week’s forecast from the #Copernicus Atmosphere Monitoring Service, “the publication reads.

The ozone layer protects the Earth from the harmful ultraviolet rays of the sun. It is found in Earth’s stratosphere, a layer of the atmosphere about 10–50 km above sea level.
Scientists attributed the hole formation in the ozone layer above the North Pole at unusually low temperatures in the atmosphere over the region. Researchers from the German Aerospace Center (DLR) discovered the hole using data from the Copernicus Sentinel-5P satellite.

“The ozone hole that we observed in the Arctic this year has a maximum extension of less than 1 million square kilometers. This is small compared to the Antarctic hole, which can reach a size of around 20 to 25 million square kilometers with a normal duration of around three to four months, “said Diego Loyola of the German Aerospace Center.
CAMS had said a similar depletion of the ozone layer over the Arctic was found in the spring of 2011.
