The hole in the ozone layer over Antarctica in 2022 had an average area slightly smaller than the extent reached in 2021, and well below the average seen in 2006 when the hole size peaked.
As NOAA and NASA announced the 2021 Antarctic ozone hole condition on October 27, the 8th- and 9th-grade science classroom at Lafayette Junior/Senior High School also concluded their first science project on ozone hole prediction.
In honor of Women’s History Month, Global Monitoring Laboratory (GML) is highlighting some of the great work done by our scientists. Today’s story expands on a previous one introducing a day in the life at the South Pole for NOAA Corps Officer Lieutenant Junior Grade Marisa Gedney, who served as a Station Officer at the Amundsen-Scott South Pole Station in Antarctica.
Persistent cold temperatures and strong circumpolar winds supported the formation of a large and deep Antarctic ozone hole that will persist into November, NOAA and NASA scientists reported today.
Abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion in September and October, resulting in the smallest ozone hole observed since 1982.
The ozone hole that forms in the upper atmosphere over Antarctica each September was slightly above average size in 2018, NOAA and NASA scientists reported today.
The fall equinox means the end of summer for the Northern Hemisphere, but marks the beginning of spring — and the first glimpse of the sun since March — for scientists at NOAA’s South Pole Atmospheric Baseline Observatory located at the Amundsen-Scott South Pole Research Station.
Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new NOAA study shows.

As hints of spring appear across the United States, NOAA’s first all-women crew at the South Pole atmospheric observatory are half a world away, ready for Antarctica’s brutal, six-month polar night.
Measurements from satellites this year showed the hole in Earth’s ozone layer that forms over Antarctica each September was the smallest observed since 1988, scientists from NASA and NOAA announced today.
The fall equinox signals the coming of winter for the Northern Hemisphere, but heralds the arrival of spring — and the first sunrise since March — for researchers at NOAA’s South Pole Atmospheric Baseline Observatory.
The Montreal Protocol has been hailed for controlling chlorine-based chemicals that created a vast hole in the ozone layer over Antarctica. But new research by British and American scientists suggest a chemical not controlled by the international treaty poses a potential risk to the Earth’s protective ozone layer.
