In the final decades of the 20th century, stratospheric ozone depletion—often called, not quite accurately, the ozone hole—was a widespread concern. Halocarbons, including chlorofluorocarbons used as ...

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 ...

This study investigates the spatiotemporal variability of surface ozone across Southeastern Nigeria (2002–2023) using Continuous Wavelet Transform (CWT), a time–frequency method that detects localized ...

In a paper appearing in the journal “Environmental Science and Technology,” MIT scientists report that they detected a clear signal of human influence on upper tropospheric ozone trends in a 17-year ...

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 ...

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 ...

The troposphere comprises the lowest layer of Earth’s atmosphere, stretching from the planet’s surface to a little over eight miles into the sky. It also contains about 10% of the ozone in the ...

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.

NASA research suggests ozone levels in Earth's troposphere probably won't be affected much by projected stronger circulating winds that transport ozone in our atmosphere. New NASA research on natural ...

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 ...
