MA number of research groups have discovered an ozone hole over the Arctic for the first time. Atmospheric researchers observed this in full for the first time via satellite data, announced the German Aerospace Center (DLR) in Oberpfaffenhofen near Munich on Wednesday. The researchers speak of an ozone hole when the protective layer becomes so thin that it falls below the normal value by about a third. A strong ozone depletion had already been observed above the North Pole. This has been encouraged by the exceptionally long-lasting and strong polar winds in the past two months.
“At the moment it is a real ozone hole as we have never seen it above the Arctic, but as we know it from the Antarctic. This is a very special event, ”said climate researcher Martin Dameris from DLR. The ozone hole over the Arctic is expected to close in ten days.
Overall, according to the scientists, the ozone layer is increasing again worldwide. The ban on the production and use of chlorofluorocarbons (CFCs) and other ozone-depleting substances is taking effect.
Parallel to the researchers in Oberpfaffenhofen, scientists from the atmospheric physics department of the Alfred Wegener Institute in Bremerhaven reported the first ozone hole above the North Pole.
