The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation.

Hello dear researcher,

Ozone (O3) which is formed in the ionosphere by the cleavage of O2 upon absorption of VUV radiation (100 - 200 nm) is trapped in a cold layer between 10 and 50 km above sea level, thus in the stratosphere. Ozone absorbs UV-C and UV-B radiation between 200 and 320 nm. Appended you will find a slide from my lecture "Incoherent light sources", while you can find the rest of the lecture uploaded to my homepage.

All the best for your research, Thomas

Atmospheric ozone has two effects on the temperature balance of the Earth. It absorbs solar ultraviolet radiation, which heats the stratosphere. It also absorbs infrared radiation emitted by the Earth's surface, effectively trapping heat in the troposphere. Ozone is extremely valuable since it absorbs a range of ultraviolet energy. When an ozone molecule absorbs even low-energy ultraviolet radiation, it splits into an ordinary oxygen molecule and a free oxygen atom. The ozone layer is the region of Earth's atmosphere responsible for absorbing sun UV rays.The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet's surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects. The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth's surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun. Ozone is a particularly effective absorber of UV radiation. As the ozone layer gets thinner, the protective filter activity of the atmosphere is progressively reduced. The ozone layer in the earth's atmosphere absorbs ultraviolet radiation coming from the sun and protects the living organisms on the earth. The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth's surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun. Most of Earth's ozone resides in the stratosphere, the layer of the atmosphere that is more than 10 kilometers (6 miles) above the surface. About 90% of atmospheric ozone is contained in the stratospheric “ozone layer”, which shields Earth's surface from harmful ultraviolet radiation emitted by the Sun. Ozone in the stratosphere protects us from ultraviolet radiation in sunlight. The ozone layer is sort of like sunscreen for planet Earth. It absorbs most of the incoming UV "light" before it reaches the ground. The ozone molecules which absorb UV radiation later re-radiate the energy as heat, warming the stratosphere.

The Earth's ozone layer is responsible for absorbing harmful ultraviolet (UV) radiation from the Sun, specifically UV-B and UV-C radiation. UV radiation is a type of electromagnetic radiation with shorter wavelengths than visible light, and prolonged exposure to UV radiation can have damaging effects on living organisms, including humans, such as sunburn, skin cancer, and damage to DNA.

Ozone (O3) is a molecule made up of three oxygen atoms bonded together, and it is concentrated in a region of the Earth's stratosphere known as the ozone layer. The ozone layer acts as a natural filter, absorbing the majority of incoming UV-B and UV-C radiation before it reaches the Earth's surface.

While ozone absorbs much of the Sun's UV radiation, some UV radiation still penetrates the atmosphere and reaches the Earth's surface. However, the majority of UV-C radiation is absorbed by molecular oxygen (O2) and ozone (O3) in the upper atmosphere, preventing it from reaching the Earth's surface.

Overall, the ozone layer plays a crucial role in protecting life on Earth by absorbing harmful UV radiation from the Sun and preventing it from reaching the Earth's surface in large quantities. This helps to maintain a hospitable environment for living organisms and contributes to the regulation of Earth's climate and ecosystems.

Earth's ozone layer is responsible for absorbing ultraviolet radiation from the sun. Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called 'good' ozone. This is in contrast to ozone in the troposphere, the lowest layer of the atmosphere, where it is an air pollutant and can be harmful to humans, animals and vegetation. The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet's surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun and sun lamps that has several harmful effects. The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world. Ozone is a particularly effective absorber of UV radiation. As the ozone layer gets thinner, the protective filter activity of the atmosphere is progressively reduced.Ozone in the stratosphere absorbs a large part of the Sun's biologically harmful ultraviolet radiation. Stratospheric ozone is considered “good” ozone because of this beneficial role. In contrast, ozone formed at Earth's surface in excess of natural amounts is humans, plants, and animals.
