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 ...

Data taken in aircraft transects of emissions plumes from rural U.S. coal-fired power plants were used to confirm and quantify the nonlinear dependence of tropospheric ozone formation on plume NOx (NO ...

The study of ozone dynamics and isotope effects encompasses the intricate chemical pathways involved in ozone formation, destruction and its isotopic composition. Research in this field has elucidated ...

WASHINGTON - When it comes to air pollution, what goes on at night can be just as important as what happens during the day, say National Oceanic and Atmospheric Administration (NOAA) scientists and ...

Warmer temperatures might be causing plants to emit more chemicals into the atmosphere, adding to one of Phoenix's worst air pollution problems.

David Fahey of the National Oceanic and Atmospheric Administration's (NOAA) Aeronomy Laboratory in Boulder, Colo., explains. The severe depletion of stratospheric ozone during the winter in Antarctica ...

Wildfires release vast amounts of visible pollutants into the atmosphere that darken skies and push people indoors to avoid unhealthy air. But a near-invisible threat to public health associated with ...

Standard methods of predicting air pollution don’t take atmospheric chlorine into account, but the chemical could be responsible for 10 percent or more of daily ozone production in local air, research ...

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 ...

The Texas Commission on Environmental Quality (TCEQ) has issued ozone pollution alerts for four of the state's largest metro areas as environmental officials warn that Thursday's weather conditions ...
