The Colorado River provides water for more than 30 million people. Increasing demand for that water combined with reduced flow and the looming threat of climate change have prompted concern about how to manage the basin’s water in coming decades. NOAA-funded researchers at the University of Washington and co-authors at eight institutions across the West aim to explain this wide range, and provide policymakers and the public with a framework for comparison.
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.
Do urban areas have an influence on incoming storm systems? NOAA's National Severe Storms Lab is trying to find out.
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.
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.
