Ozone layer - Wikipedia
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.
NASA Ozone Watch: Latest status of ozone
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. Click any map image to bring up a new page with a high-resolution image.
Ozone layer | Description, Importance, & Facts | Britannica
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.
NASA Knows: The Ozone Hole - NASA Science
The ozone layer shields Earth from ultraviolet (UV) radiation from the Sun that can harm plants, animals, and humans. The ozone layer forms in the stratosphere 7-31 miles (11–50 km) above the Earth's surface.

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.
What Is Earth’s Ozone Layer and Why Is It Important?
This silent protector is Earth’s ozone layer—a thin band of gas that forms a shield around our planet, defending us from the Sun’s most dangerous rays. Without it, Earth as we know it would be a scorched and uninhabitable world.
Ozone - Wikipedia
Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Earth's atmosphere. It is present in very low concentrations throughout the atmosphere, with its highest concentration high in the ozone layer of the stratosphere, which absorbs most of the Sun 's ultraviolet (UV) radiation.
