Emissions from oil and natural gas operations north of Denver are releasing gases into the air that could add to ozone pollution in the region.
Warmer air temperatures high above the Antarctic led to the second smallest seasonal ozone hole in 20 years, according to NOAA and NASA satellite measurements
A team of scientists from NOAA and the University of Colorado-CIRES will receive the governor’s Award for High-Impact Research for discoveries made during the Deepwater Horizon oil spill crisis.
A new study directly measures the heat-trapping effect of wildfires during an actual wildfire that burned near Boulder, Colo., in 2010.
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.
In California’s Los Angeles Basin, levels of some vehicle-related air pollutants have decreased by about 98 percent since the 1960s, even as area residents now burn three times as much gasoline and diesel fuel.
Arctic warming has thinned springtime sea ice across the Arctic Ocean. A new study shows that this alters the chemistry of the atmosphere near the Earth’s surface and may increase the amount of toxic mercury contaminating the region.
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.
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.
