Annual Antarctic ozone hole larger and formed later in 2015

The 2015 Antarctic ozone hole area was larger and formed later than in recent years, according to scientists from NOAA and NASA.

On Oct. 2, 2015, the ozone hole expanded to its peak of 28.2 million square kilometers (10.9 million square miles), an area larger than the continent of North America. Throughout October, the hole remained large and set many area daily records.

Antarctic ozone hole similar to last year

Antarctic ozone hole similar to last year

The Antarctic ozone hole, which forms annually in the August to October period, reached its peak size on September 11, stretching to 9.3 million square miles (24.1 million square kilometers), roughly the same size as last year’s peak of 9.3 million square miles (24 million square kilometers) on September 16, 2013. This is an area similar in size to North America.

Encouraging information from this year’s observations of the Antarctic ozone hole

Encouraging information from this year’s observations of the Antarctic ozone hole

For nearly 50 years, scientists with NOAA have launched high-altitude balloons from the South Pole, to understand why a hole was forming in the protective ozone layer high in the atmosphere. Now, organizations around the world track the infamous ozone hole through these ballon-sondes, satellite measurements and ground instruments.
