The Annual Greenhouse Gas Index is a measure of the climate-warming influence of long-lived trace greenhouse gases in the atmosphere and how that influence has changed since the onset of the industrial revolution.
The goal of the study is to improve the accuracy of weather and river flow forecasts in watersheds critical to the southwestern U.S. water supply.
The Southern Ocean plays a central role in moderating the rate of climate change, absorbing an estimated 40% of the total amount of human-generated carbon dioxide emissions and 60-90% of the excess heat trapped by greenhouse gases in the atmosphere. A new study led by scientists from NOAA's Pacific Marine Environmental Laboratory quantifies for the first time how many billions of tons of carbon are removed from the atmosphere every year by biological activity.
NOAA scientist Andrew Rollins was unsatisfied with the current, research-grade instrument for measuring nitrogen oxides. So he built a better one.
A team led by NOAA researchers used a combination of observations and computer models to generate the first broad assessment of bottom marine heat waves in the productive continental shelf waters surrounding North America.
A new NOAA analysis shows U.S. emissions estimates of the super-potent greenhouse gas sulfur hexafluoride and shows they have declined between 2007-2018.
Flying out of Eielson Air Force Base in Fairbanks, Alaska, a NASA WB-57 research jet carrying a payload of sampling instruments into the stratosphere will gather measurements of trace gases and aerosols in an undersampled region of the atmosphere.
Smoke from wildfire-generated thunderstorms has greater impacts on the stratosphre, lasts longer and acts differently than scientists previously thought, a new research paper in the journal Science concludes.
A scientist with NOAA's Pacific Marine Environmental Laboratory led development of a guide to help marine resource managers use environmental DNA to collect detailed information about the biodiversity of their study areas.
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.
