Ozone layer measurement

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 (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosph… WebOct 23, 2024 · ozone layer is a concentration of ozone molecules in the stratosphere . About 90 percent of the planet's ozone is in the ozone layer. The layer of the Earth's atmosphere that surrounds us is called the troposphere . The stratosphere, the next higher layer, extends about 6 to 31 miles (or 10 to 50 kilometers) above the Earth's surface.
