Smaller Ozone Hole This Year - Universe Today
The ozone hole that developed above Antarctica looks smaller this year than previous years, based on observations from NASA's Aura satellite. The largest hole was measured in 1998; almost triple the size of 1985's hole. The temperature of the atmosphere above Antarctica seems to be one of the biggest factors deciding the size of the ozone hole - the colder it gets, the more ozone that's destroyed.
