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.

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. Ozone is a gas composed of three oxygen atoms. Many ...
