The monitoring service of the Copernicus atmosphere (CAMS) reported on Twitter that the ozone hole that was discovered over the Arctic last month has dragged on.
The ozone layer protects the Earth from harmful ultraviolet rays of the Sun. It is in the stratosphere, at altitudes from 10 to 50 kilometers above sea level.
Scientists link the formation of a hole in the ozone layer over the North pole with unusually low temperatures of the atmosphere in this region. Found a hole the researchers from the German aerospace centre (DLR) using the Copernicus satellite Sentinel-5P.

The unprecedented 2020 northern hemisphere #OzoneHole has come to an end. The #PolarVortex split, allowing #ozone-rich air into the Arctic, closely matching last week's forecast from the #CopernicusAtmosphere Monitoring Service.

“The ozone hole, which we have observed over the Arctic this year, had an area of almost one million square kilometers. It is a bit when compared with a hole over Antarctica, which may have a surface area of from 20 to 25 million square kilometers for three to four months,” said Diego Loyola German aerospace center.
