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. Approximately 90 percent of the atmosphere’s ozone occurs from 10–18 km (6–11 miles) to about 50 km (about 30 miles) above Earth’s surface.

The Ozone Hole NASA Knows: The Ozone Hole This is the story of the hole in Earth's protective ozone layer: what it is, how it formed, and the decades-long effort to repair it.
What Is Earth’s Ozone Layer and Why Is It Important?
The ozone layer remains vital—not just as a shield against UV radiation, but as a symbol of what is possible when nations unite to solve a common threat. The Human Connection: Ozone and Health The consequences of a thinning ozone layer are not theoretical. They touch real lives, in real places.
Ozone - Wikipedia
2 (dioxygen). 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.
Ozone Layer - National Geographic Society
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.
