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.

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.

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.

Antarctic ozone hole about average in 2016
The hole in the Earth’s ozone layer that forms over Antarctica each September grew to about 8.9 million square miles in 2016 before starting to recover, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA) who monitor the annual phenomenon.

4 ways the ozone hole is linked to climate, and 1 way it isn’t
To mark the peak of ozone hole season, we’re highlighting four ways that climate and the ozone hole are related—and one important way they aren’t.

South Pole is last place on Earth to pass global warming milestone
The Earth passed another unfortunate milestone May 23 when carbon dioxide surpassed 400 parts per million (ppm) at the South Pole for the first time in 4 million years.

Last light: Sunset at the South Pole
In the Northern Hemisphere, the spring equinox promises warmer days and green plants. But for researchers at NOAA's South Pole Atmospheric Baseline Observatory, Sunday March 20 marks the start of the austral autumn, the last time they see the sun for six months.

2015 Sets a Record Low for Antarctic Ozone Hole in October
NOAA’s measurements of ozone at South Pole registered a record low for the month of October. This year, the average amount of ozone measured by a Dobson instrument at South Pole in the second half of October was 114 Dobson Units (DU), or 60 percent below the pre-ozone hole conditions.
