Ozone - Wikipedia
Levels of ozone at various altitudes and blocking of different bands of ultraviolet radiation. Essentially all UVC (100–280 nm) is blocked by dioxygen (at 100–200 nm) or by ozone (at 200–280 nm) in the atmosphere.
What is Ozone? - US EPA
Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The "ozone layer," approximately 6 through 30 miles above the Earth's surface, reduces the amount of harmful UV radiation reaching the Earth's surface.
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.
What is Ozone (O₃)? - Clean Air Initiative
Quick Answer: Ground-level ozone (O₃) is a colorless gas that forms when nitrogen oxides (NOₓ) and volatile organic compounds (VOCs) react in sunlight. Unlike protective ozone in the upper atmosphere, ground-level ozone is a harmful air pollutant that can damage your lungs and respiratory system.
Ozone - American Lung Association
Ozone (also called smog) is one of the most dangerous and widespread pollutants in the U.S. It may be hard to imagine that pollution could be invisible, but ozone begins that way. As ozone concentrates and mixes with other pollutants, we often call it by its older, more common name—smog.
Ozone | Definition, Properties, Air Pollution, Importance, Structure ...
Ozone is an irritating pale blue gas that is explosive and toxic, even at low concentrations. It occurs naturally in small amounts in Earth’s stratosphere, where it absorbs solar ultraviolet radiation, which otherwise could cause severe damage to living organisms on Earth’s surface.
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 (O 3).
