NASA, the Utah Division of Air Quality and several universities are teaming up to find out why the Salt Lake Valley has so ...

A newly published study notes that ozone pollution has risen over the past 20 years in the Northern Hemisphere. The research, published in Science Advances, notes the level of the greenhouse gas ...

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 ...

In a first-ever study using ozone data collected by commercial aircraft, researchers from the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder ...

In North America and Europe, emissions of ozone precursors such as nitrogen oxides (NO x) and volatile organic compounds (VOCs) declined by half between 2000 and 2018. However, the ozone content of ...

Nitrogen, volatile organic compounds and sunlight are the three ingredients that form the smog that regularly chokes people and plants, causing tens of thousands of respiratory-related deaths and ...

The U.S. Environmental Protection Agency (EPA) claims, based on climate change models, that there is a connection between climate change, ozone in outdoor air, and health effects, including asthma.

In a first-ever study using ozone data from commercial aircraft, researchers found that levels of the pollutant in the lowest part of Earth's atmosphere have increased across the Northern Hemisphere ...

The primary regulated emissions from gasoline-fueled automobiles and trucks—volatile organic compounds (VOCs), nitrogen oxides (NO x), and carbon monoxide (CO)—all contribute to the formation of ...
