Ozone is one of the highly reactive gases, which is photo chemically active. It is composed of three atoms of oxygen (O3) and its role depends on its location in the atmosphere. This gas plays a ...

Ozone (O3) is a key constituent of the troposphere. Photochemical and chemical reactions involving it drive many of the chemical processes that occur in the atmosphere by day and by night. At ...

Specific measures could already have a positive impact on climate protection and public health. These measures do not replace those related to carbon dioxide, and their full implementation could ...

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 ...

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 ...

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 ...

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 ...

The observed depletion of the ozone layer from the 1980s onwards is attributed to halogen source gases emitted by human activities. However, the precision of this attribution is complicated by year-to ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

Despite rapid progress in clean energy and electric vehicles, the world is still warming faster than ever. The good news is ...

A recent IITM-Pune study has revealed that human activities, such as burning fuel, have caused an increase in pollutant nitrogen oxide (NOx) emission that in turn has caused a surge in greenhouse gas ...
