Ozone can be an agent of good or harm, depending on where you find it in the atmosphere. Way up in the stratosphere, the colorless gas shields the Earth from the sun’s harsh ultraviolet rays. But ...

A research team led by Prof. SI Fuqi from Anhui Institute of Optics and Fine Mechanics (AIOFM), Hefei Institutes of physical Science (HFIPS) of Chinese Academy of Sciences (CAS) developed a new method ...

The stratospheric ozone layer exists 10 to 25 miles above the Earth's surface and protects us from harmful ultraviolet radiation, but down here in the troposphere, ozone buildup can impact human ...

An NRC committee will evaluate the scientific and technical bases of approaches used by EPA for estimating ozone mortality risk reduction and associated benefits of health-based standards over time.

In the stratosphere, ozone acts as a protective layer. But in the troposphere, at ground level, this colorless gas is incredibly harmful to human health and the environment in ways scientists are ...

New research has identified a lesser-known form of ozone playing a big role in heating the Southern Ocean -- one of Earth's main cooling systems. New research has identified a lesser-known form of ...

Ozone may be weakening one of the Earth’s most important cooling mechanisms, making it a more significant greenhouse gas than previously thought, research has found. A new study has revealed that ...

Scientists confirmed that much of ozone's increase in the upper troposphere is likely due to humans. A team detected a clear signal of human influence on upper tropospheric ozone trends in a 17-year ...
