ozone, definition of
Ozone is a colorless, odorless reactive gas comprised of three oxygen atoms. It is found naturally in the earth’s stratosphere, where it absorbs the ultraviolet component of incoming solar radiation that could be harmful to life on earth. Ozone is also found near the earth’s surface, where pollutants emitted from society’s activities react in the presence of sunlight to form ozone.

- This year's ozone hole could be the smallest it has been in 30 years
For decades, scientists have closely observed the ozone layer, which protects Earth from the sun's harmful ultraviolet (UV) radiation. This year, just in time for World Ozone Day, the European Union's Copernicus Atmosphere Monitoring Service (CAMS) announced...
- New paper connects upper stratospheric ozone changes to the solar cycle
The authors write in this plain language summary: Changes in the output of the Sun are thought to influence surface weather and climate through a set of processes initiated by the enhancement of upper stratosphere (32‐48 km) ozone...
- China’s war on particulate air pollution is causing more severe ozone pollution
From Eurekalert! Public Release: 2-Jan-2019 PM 2.5 pollution is falling but ground-level ozone pollution is on the rise Harvard John A. Paulson School of Engineering and Applied Sciences In early 2013, the Chinese government declared a war on air pollution...
- The ozone is finally healing and could be completely repaired by 2060
Finally, some good news about the environment. Earlier this week, the United Nations announced in a report that the ozone layer is on the mend. If the current recovery rate continues, parts of the ozone could be fully repaired by the 2030s. The entire...
- Despite growing larger this year, NASA says the Antarctic ozone hole is healing
This year, the South Pole region of Antarctica was slightly colder than the previous few years, so the ozone hole grew larger. However, scientists from NASA have developed models to predict what the ozone layer would have looked like without the Montreal...

From the University of Bristol The compound, carbon tetrachloride, contributes to the destruction of the Earth’s ozone layer, which protects us from harmful ultraviolet radiation...
- Levels of ozone-destroying CFCs are mysteriously rising
Globally banned by the Montreal protocol in 1987 for their ozone-destroying properties, chlorofluorocarbon (CFC) chemicals are experiencing a comeback. In recent years, levels of CFCs have increased suddenly and mysteriously. Now, scientists are racing...
- Ooops. Despite Montreal Protocol, ozone-destroying CFC’s on the rise
NOAA finds rising emissions of ozone-destroying chemical banned by Montreal Protocol Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production...

What is ozone?
- Ozone Depleting Substance
A family of man-made compounds that includes, but are not limited to, chlorofluorocarbons (CFCs), bromofluorocarbons (halons), methyl chloroform, carbon tetrachloride, methyl bromide, and hydrochlorofluorocarbons (HCFCs). These compounds have been shown to deplete stratospheric ozone, and therefore are typically referred to as ODSs.

- Ozone Precursors
Chemical compounds, such as carbon monoxide, methane, non-methane hydrocarbons, and nitrogen oxides, which in the presence of solar radiation react with other chemical compounds to form ozone, mainly in the troposphere.
