Observational Constraints Reveal Biases in OVOC-Driven Radical Chemistry. Schematic illustration of how limited OVOC constraints bias simulations of radical (ROₓ) chemistry and ozone formation. When ...

Ozone is a chemical compound consisting of three Oxygen atoms (O 3). The Oxygen we breathe is made of two atoms (O 2). Ozone is primarily found in the Ozone Layer in the stratosphere, however, it can ...

There are two different kinds of ozone that we need to understand first. There is stratospheric ozone and tropospheric ozone. Stratospheric ozone is probably the kind that pops into your head when we ...

NASA and NOAA scientists ranked the 2025 Antarctic ozone hole as the fifth smallest since 1992, a finding that reflects decades of global chemical regulation but does not mean the threat has passed.

The 2015 Antarctic ozone hole area was larger and formed later than in recent years, said scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). On Oct. 2, 2015, the ...

Treating methane as an afterthought in air quality policy is no longer a technical oversight but a political choice, with measurable consequences for citizens’ health, farmers’ livelihoods and ...

Expect moderate levels of ground-level ozone, an urban pollutant that can affect those with sensitive respiratory systems, to be in the skies over the Houston metro area on Friday, according to Texas ...
