The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone (O 3 ) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.

6 天之前 · 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.

2025年1月17日 · ozone layer, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules (O 3).

2023年3月13日 · The stratosphere includes the zone commonly called the ‘ozone layer’. It plays a crucial role in keeping the planet habitable by absorbing potentially dangerous ultraviolet (UV-B) radiation from the sun. Before its depletion, the ozone layer typically absorbed 97 to 99% of incoming UV-B radiation.

2024年9月17日 · Learn about the ozone layer and how human activities deplete it. This page provides information on the chemical processes that lead to ozone layer depletion, and scientists' efforts to understand them.

2023年1月10日 · What is the ozone layer, and why does it matter? Human activity has damaged this protective layer of the stratosphere, but scientists say the ozone layer is on track for recovery.

2023年10月19日 · The ozone layer is one layer of the stratosphere, the second layer of Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet. The stratosphere gets its name because it is stratified, or layered: as elevation increases, the stratosphere gets warmer.

2024年11月18日 · Why is the ozone layer important? What is ozone depletion, and how does it occur? What is the ozone hole? What is the connection between ozone depletion and climate change? How do we know that natural sources are not responsible for ozone depletion? What is being done about ozone depletion?

2015年7月12日 · The ozone layer is a layer in the Earth's atmosphere containing high concentrations of ozone. It is typically said to exist between about 20 and 30km above the Earth's surface, but it does not have definite edges. You can see this on the ozone map.

2024年12月20日 · Most of the ozone present in the atmosphere is concentrated in the stratospheric “ozone layer,” about 9 to 22 miles (15 – 35 km) above the surface (around twice the altitude at which commercial airplanes fly).
