2025年2月1日 · View the latest status of the ozone layer over the Antarctic, with a focus on the ozone hole. Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone.

In 2019, abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion, leading to the smallest hole since 1982. Models predict that the Antarctic ozone layer will mostly recover by 2040.

2024年10月30日 · Does a smaller hole mean that Antarctic ozone is recovering? Not yet, say NASA scientists. A deeper look at the ozone hole shows that for now weather still has a bigger influence on the size of the ozone hole than policies that limited emissions of …

2024年10月30日 · The ozone hole over Antarctica averaged nearly 8 million square miles (20 million square kilometers) between Sept. 7 and Oct. 13, 2024, the 20th smallest extent in 45 years. Credit: NASA’s Goddard Space Flight Center/ Kathleen Gaeta

2024年10月30日 · Healing continues in the atmosphere over the Antarctic: A hole that opens annually in the ozone layer over Earth's southern pole was relatively small in 2024 compared to other years. NOAA and NASA scientists project the ozone layer could fully recover by 2066.

2025年1月28日 · While it’s taken several decades to see substantial improvement, the ozone hole started to heal in 2000. In 2021, the hole over Antarctica was the seventh smallest since recovery started in 1992. Ozone hole recovery projection, 1960-2100. Ozone levels stabilized in the 1990s following the Montreal Protocol, and have started to recover.

2023年11月1日 · The 2023 Antarctic ozone hole reached its maximum size on Sept. 21, according to annual satellite and balloon-based measurements made by NASA and NOAA. At 10 million square miles, or 26 million square kilometers, the hole ranked as the 12th largest single-day ozone hole since 1979.

2024年10月30日 · This year, the ozone hole over Antarctica reached its annual maximum extent on September 28th, 2024, with an area of 8.5 million square miles (22.4 square million kilometers.) The hole, which is actually a region of depleted ozone, was the 20th smallest since scientists began recording the ozone hole in 1979.

2023年11月1日 · The 2023 Antarctic ozone hole reached its maximum size at 10 million square miles (26 million square kilometers) on September 21, which ranks as the 12 th largest since 1979, according to annual satellite and balloon-based measurements made by NOAA and NASA.

2023年11月1日 · The 2023 Antarctic ozone hole reached its maximum size at 10 million square miles, or 26 million square kilometers, on Sept. 21, which ranks as the 16th largest since 1979, according to annual satellite and balloon-based measurements made by NASA and NOAA.
