What is the Ozone Hole? The ozone hole is not technically a “hole” where no ozone is present, but is actually a region of exceptionally depleted ozone in the stratosphere over the Antarctic that happens at the beginning of Southern Hemisphere spring (August–October).
Ozone is mostly found in the stratosphere, a layer of the atmosphere between six and 30 miles (10-50 km) above the Earth's surface. This ozone layer forms an invisible protective shield...
Hace 5 días · View the latest status of the ozone layer over the Antarctic, with a focus on the ozone hole. Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone.
