New analyses of global air measurements show that five years after an unexpected spike in emissions of the banned ozone-depleting chemical chlorofluorocarbon CFC-11, they dropped sharply between 2018 and 2019.
Understanding the biologic contribution of CO2 to megacities' overall carbon emissions will be important for designing and evaluating mitigation strategies.
A miniaturized aerosol spectrometer developed by scientists in NOAA’s Chemical Sciences Labotatory will be one of several insttuments making sure air in the living spaces of the International Space Station stays safe.
A NOAA study published in Nature Geosciences takes a new look at faint, old smoke and finds that it is just as important an influence on the climate as the thick plumes produced by active fires.
It's not every day you get a message from space.
Weather conditions were ripe for a big ozone hole this year. But declining levels of ozone-depleting chemicals kept it to near-average size.
Nearly 200 scientists and managers from government, academia, and private industry gathered Sept. 10-12 at the NOAA Center for Weather and Climate Prediction in College Park, Maryland from September 10-12, 2018. This inaugural event brought the NOAA modeling community together to share ideas on how to advance modeling and network with other professionals.
New research finds the temperature of a wildfire is a better predictor of what’s in the smoke than the type of fuel being burned - a surprising result that will advance a wildfire smoke-modeling tool currently under development.
Understanding how wildfires impact air pollution and the composition of Earth’s atmosphere is critical for communities near and far because smoke from wildfires can travel long distances and have adverse health impacts on citizens.
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.
