Highlight: The largest Ozone layer hole over the Arctic which was about 1 million square kilometers is covered now.
Scientists recently verified that the largest Ozone layer hole above the Arctic has been closed. The hole was about 1 million square kilometers has now self-healed, as per the reports.
In March 2020, scientists first identified the hole which was created due to periodic unusual changes in the atmosphere.
The news was verified by The Copernicus Climate Change Service (C3S) and Copernicus Atmosphere Monitoring Service (CAMS) by the European Centre For Medium-Range Weather Forecasts (ECWMF).
The European Satellite Monitoring Agency declared the recovery of the Ozone hole via tweet, stating that finally, the 2020 Northern Hemisphere Ozone hole has come to an end.
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 purpose of the closing of Ozone Hole:
The scientists report that the cause for the recovery of a 1 million square kilometer hole in the Ozone layer is the polar vortex. It is a high altitude current which is majorly responsible for blowing frigid air to the polar regions.
The report also stated that the closure of the largest hole in the Ozone layer is not due to the reduction of pollution amid Coronavirus lockdown.
The formation of the hole above the North Pole in the Ozone layer was observed in March. Hence it was anticipated due to the result of low temperature. Though it was forecast that the largest Ozone layer hole would have led to a serious cause and had been moved to the south.
