The record-breaking ozone layer hole in the Arctic finally healed according to scientific reports. This great news was shared by Copernicus Atmosphere Monitoring Service (CAMS) through a twitter post last week.
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.

What is CAMS?
CAMS is an organization implemented by the European Centre for Medium-Range Weather Forecasts on behalf of the European Commission.
How big is the Ozone Layer hole?
The hole was formed late in March and this has a measure of 1 Million Square Kilometer.
Here’s the monitoring of the unusual ozone hole that was formed over the Arctic from CAMS.
What caused the ozone layer to deplete?
Science News explained in a blog post, “A powerful polar vortex has trapped especially frigid air in the atmosphere above the North Pole, allowing high-altitude clouds to form in the stratosphere, where the ozone layer also sits. Within those clouds, chlorofluorocarbons and hydrochlorofluorocarbons already high in the atmosphere — gases used as refrigerants — react with ultraviolet rays from the sun to release chlorine and bromine atoms, which in turn react with and deplete the ozone.”
The Reason Why the Ozone Layer Hole Closed
CAMS clarified in a tweet that the pandemic-related and lockdown measures throughout the globe have nothing to do with the healing of the hole. CAMS said that the closing of the large hole in the ozone layer was driven by an unusually strong and long-lived polar vortex.
This Arctic ozone hole actually has nothing to do with coronavirus-related lockdowns, but rather was caused by an unusually strong and long-lived polar vortex. This article explains what caused it in more detail: https://t.co/Nf6AfjaYRi
