The Southern Ocean that encircles Antarctica lends a considerable hand in keeping Earth's temperature hospitable by soaking up half of the human-made carbon in the atmosphere and a majority of the planet's excess heat. Yet, the inner workings — and global importance — of this ocean that accounts for 30 percent of the world's ocean area remains relatively unknown to scientists, as observations remain hindered by dangerous seas.
We sat down with Richard Artz, environmental scientist at NOAA’s Air Resources Laboratory, to learn more about the new global assessment of air pollutants that fall to the earth in precipitation and in dry form. The assessment is available online in the journal Atmospheric Environment.
Scientists this summer are taking one of the most detailed looks ever at the natural and manmade emissions that affect air quality in the Southeast, and their movement and chemical transformations within the atmosphere. The mission should help scientists determine the origin of the fine particles and how they contribute to the haziness in the region and affect regional air quality and temperature trends.
The cleanup of California’s tailpipe emissions over the last few decades has not only reduced ozone pollution in the Los Angeles area, it has also altered the pollution chemistry in the atmosphere, making the eye-stinging “organic nitrate” component of air pollution plummet, according to a new study.
Ethanol, now used commonly in U.S. transportation fuels, is turning up in urban air at more than six times the levels measured a decade ago, according to a new study by a team of NOAA researchers and colleagues.
The White House today named two NOAA scientists and a NOAA-funded scientist as recipients of the 2011 Presidential Early Career Award for Scientists and Engineers.
Today marks the beginning of a large-scale, comprehensive field project to measure how thunderstorms transport, produce and process chemicals that form ozone, a greenhouse gas that affects Earth's climate, air quality and weather patterns.
A smoke-related chemical, isocyanic acid, may be a significant air pollutant in some parts of the world, especially where forest fires and other forms of biomass burning are common.
Springtime air pollution from Asia, swept across the Pacific Ocean on winds, can contribute to episodes of high surface ozone pollution in the western United States.
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
