Antarctic ozone hole slightly smaller in 2022

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.

A lucky guess? Learn the science of ozone depletion with NOAA and NASA!

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.

Antarctic ozone hole is 13th largest on record and expected to persist into November

The 2021 Antarctic ozone hole reached its maximum area on October 7 and ranks 13th largest since 1979, scientists from NOAA and NASA reported today.

Women’s History Month: A conversation with NOAA Corps Officer LTJG Marisa about her 13 months “on the ice”

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.

Large, deep Antarctic ozone hole to persist into November

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.

2019 ozone hole smallest on record

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.

Ozone hole modest despite conditions ripe for depletion

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.

Photo feature: A ‘welcoming’ sun returns to the South Pole

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 ozone-destroying chemical controlled by Montreal Protocol rising again, NOAA data shows

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.

Warm air helped make 2017 ozone hole smallest since 1988

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.

South Pole sees first sunrise in 6 months with arrival of spring

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.

Possible new threat to Earth’s ozone layer

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.
