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.
A new study, led by NOAA and its Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder, used a novel approach to trace methane in the Los Angeles basin back to its sources, and found that "extra" methane is likely coming from sources related to fossil fuels.
As our planet is warming, not only have Earth’s climate zones begun to shift – the pace of change is expected to accelerate, according to a new study led by the NOAA Cooperative Institute for Research in Environmental Sciences at the University of Colorado.
A new observational study that did not use temperature recordings from land stations has confirmed global land warming.
Clouds over the central Greenland Ice Sheet last July were “just right” for driving surface temperatures there above the melting point.
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.
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.
