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.

Over the Arctic almost closed the ozone hole, which was formed a few months ago.
About the recovery of the ozone layer over the North pole said on Twitter, the monitoring Service of the atmosphere of the European program Copernicus.
In the early spring in the Arctic at a height of 18 miles, scientists recorded a drop in ozone content at 90 percent. Over the Northern continent there was a huge ozone hole.
Experts have considered it unusual, because the variables of temperature and rare education of mother of pearl clouds at the North pole, unlike the South, does not contribute to the active ozone depletion (in the southern ozone hole are seasonal and are produced annually).
Latest satellite data showed that the active chlorine that destroys stratospheric ozone over the Arctic has almost disappeared, and the ozone layer is recovering.
