Initial measurements from GOME-2: No substantial recovery in the ozone hole

Every year in the southern hemisphere spring, a considerable chemical reduction in ozone is observed in the lower and middle stratosphere, which extends from 10 to 15 kilometres high. The term "ozone hole" was coined to describe this phenomenon. Its expansion shows strong annual progression. Its size has varied considerably over the years, but the ozone layer shows no signs of overall recovery. This was the discovery of scientists from the German Aerospace Center (DLR) when they analysed data from the EUMETSAT MetOp Earth monitoring satellite.
