stratosphere ozone layer

With a weakening of this shield, we would be more susceptible to … Life as we know it wouldn’t be possible without this layer of protection. View the latest status of the ozone layer over the Antarctic, with a focus on the ozone hole. Ozone occurs both in the Earth's upper atmosphere and at ground level. It extends anywhere from 4 to 12 miles (6 to 20 km) above Earth's surface up to 31 miles (50 km). What helped correct ozone layer thinning? Click any map image to bring up a new page with a high-resolution image. The ozone layer, the one that protects us from radiation that comes from the Sun and outer space, is found in the stratosphere. Stratospheric ozone (the ozone layer) is beneficial because it absorbs dangerous high-energy ultraviolet light. Ozone is mainly found in two regions of the Earth's atmosphere. Find out what caused the ozone hole, and how the 1989 Montreal Protocol sought to put an end to ozone depletion. Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun's harmful ultraviolet rays. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. The stratospheric ozone layer protects life on Earth by absorbing ultraviolet light, which damages DNA in plants and animals (including humans) and leads to sunburns and skin cancer. Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone. Ozone can be good or bad, depending on where it is found. Prior to 1979, scientists had not observed atmospheric ozone concentrations below 220 Dobson Units. Ozone is also found much nearer the ground, in the troposphere, the lowest level of Earth’s atmosphere. The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation from the sun. Most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the Earth's surface and extends up to about 30 miles (50 kilometers). The stratosphere is the next layer of the atmosphere. The ozone layer helps to protect life from harmful ultraviolet radiation. The emission of ozone depleting substances has been damaging the ozone layer. In 1987, the United Nations established the Montreal Protocol to regulate the quantities of these gases in the atmosphere. Visit other layers in Earth's atmosphere. This is the layer where most commercial airliners fly and weather balloons travel to. The Stratosphere: Ozone's Home . The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. The stratospheric ozone layer, roughly 7 to 25 miles above Earth’s surface, is a natural sunscreen, absorbing harmful ultraviolet radiation that can damage plants and animals and affect people by causing cataracts, skin cancer and suppressed immune systems. But through domestic and international action, the ozone layer is … Fixing the ozone hole is a matter of ensuring that no ozone-depleting gases reach the stratosphere. Most ozone resides in the stratosphere (a layer of the atmosphere between 10 and 40 km above us), where it acts as a shield to protect Earth's surface from the sun's harmful ultraviolet radiation. The stratosphere is where you’ll find the very important ozone layer. Ozone is a highly reactive molecule comprised of three oxygen atoms that occurs naturally in small amounts.
