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 ...

Tropospheric ozone, a secondary pollutant formed by sunlight-driven reactions of nitrogen oxides and volatile organic compounds, plays a dual role as a harmful air pollutant and a short-lived climate ...

Tropospheric ozone is generated from precursor pollutants, but can be blown far afield. Satellite observations show rising ozone levels over China — and almost stable levels over western North America ...

Ground level ozone (O3) also tropospheric ozone, is a trace gas of the troposphere, with an average concentration of 20–30 parts per billion by volume (ppbv), with close to 100 ppbv in polluted areas.

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 ...

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 ...

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 ...

Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms (O3) and its production occurs in two layers of the atmosphere, i.e. troposphere and stratosphere. It is blue in ...

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 ...

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 ...

A new study shows that during drought, it's not how hot or how dry it is that determines gas emissions from plants—but how quickly conditions change. This discovery reshapes our understanding of the ...
