Findings of a new study of aerosols in the remote atmosphere finds that the northern stratosphere is significantlly more polluted than the south. Analysis of the aerosols suggests aviation is to blame.
Two independent types of measurements show a strong warming trend during the 14-year period from 2005 to 2019.
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.
