NASA: Ozone hole over Antarctica smallest in 30 years
November 8th, 2017
The ozone hole that forms over Antarctica every year in September was found to be the smallest this year since 1988. This was revealed by the NASA satellite measurements from 2017. According to NASA scientists, the hole in the ozone layer reached its peak extent on September 11, covering an area about two and a half times the size of the US – and then it declined through the remaining part of September. The ground- and balloon-based measurements from the National Oceanic and Atmospheric Administration (NOAA) also showed the least amount of ozone depletion above the continent during the peak of the ozone depletion cycle since 1988.
