The ozone hole is now larger than Antarctica – Earth and the poles

This year the ozone hole has reached a greater extension than Antarctica, which is one of the largest and deepest in recent years: this is shown by the observations of the Sentinel 5B satellite, one of the Earth Sentinels of the Copernicus program administered by the Commission. European and European Space Agency (ESA). Data were collected as part of the European Center’s Copernicus Atmospheric Monitoring Service (CAMS) for medium-sized weather forecasts. This figure coincides with the International Day for the Protection of the Ozone Layer, which is being celebrated today.

The hole in the ozone layer forms in the spring between August and October each year and peaks in mid-September to mid-October. This year, after a very normal initial level, it increased dramatically last week, now 75% larger than measurements taken at the same time as 1979.

Vincent-Henry Peugeot, director of the Copernicus Atmospheric Monitoring Service, noted: “This year the ozone hole has become one of the longest ever recorded.” “Ozone hole monitoring at the South Pole should be explained with caution because the size, duration and concentration are affected by local winds. However, we expect it to close by 2050,” Antje Innas of the European Center for Moderate Weather Forecasts said.

At the end of the Southern Hemisphere spring, when temperatures begin to rise in the upper stratosphere, ozone depletion decreases, the polar vortex weakens and eventually breaks down, bringing ozone levels back to normal by December.
