Ozone pollution in India is damaging millions of tons of the country’s major crops, according to a new study by an international team of researchers. The pollution caused losses of more than $1 billion in a single year, destroying enough food to feed an estimated 94 million people.
Researchers at NCAR and partner organizations this summer are using aircraft, ground-based sensors, computer models, and other tools to track the origins of summertime ozone, a significant health threat.
California will likely experience more large fires in forested areas this century because of rising temperatures and changes in precipitation along with development patterns, new research finds. The blazes could increase some types of fire-generated air pollution by more than half.
Geophysical Research Letters, a leading journal in Earth science, is toasting its 40th anniversary this month with an editor-picked retrospective collection of 40 papers, including several with authors from NCAR.
A new study by an NCAR researcher shows that small- to moderate-size volcanoes have helped slow down warming over the last decade, while industrial emissions of Sun-blocking sulfur dioxide over Asia have contributed relatively little to the slowdown.
A team of researchers, including NCAR scientist Carl Schmitt, are climbing high in the Peruvian Andes to assess the extent to which the white ice is being darkened by ash and other particulates that are emitted by nearby industrial operations. The dark particles can accelerate glacial melting, eventually threatening runoff that supplies water for millions of South American residents.
Scientists are analyzing results from a project that pulled together chemists, radar experts, cloud physicists, forecasters, pilots, and other specialists to investigate the evolution of thunderstorms.
After an earthquake and tsunami damaged the Daiichi nuclear power plant in Fukushima, Japan, on March 11, 2011, an unknown quantity of radioactive material was released into the surrounding air and sea.
Atmospheric carbon dioxide has been increasing fairly steadily for decades, but methane has accumulated at a more erratic pace. The increase virtually stalled for much of the last decade before resuming after 2007.
Hazy skies and fiery sunsets were noted across much of the central United States after the huge Wallow Fire developed in Arizona. But there’s also a quantitative way to track fire’s impact on the surrounding air.
New research focusing on the Houston area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea.
The air in the vicinity of Earth’s biggest urban areas includes a wild variety of constituents emitted by cars, factories, trees, and much more. Tracking the fate of such air as it spreads outward is no simple task.
