New research from NOAA finds that fragrant personal care products - the stuff that makes you smell good - are now responsible for a significant amount of the ozone pollution known as smog that plagues major urban areas.
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.
The dynamics that lift smoke from large wildfires into the upper atmosphere could potentially be employed one day to help temporarily cool the planet, based on the findings of a modeling study led by NOAA scientists.
Massive high-altitude clouds of smoke warmed the Southern Hemisphere's stratospshere by about 1 degree Celsius for six months, and likely contributed to the large and persistent ozone hole that formed over Antarctica during the austral spring.
Researchers have mapped global ground-level ozone concentrations by year for the Global Burden of Disease study using a data fusion approach, the first time this method was applied to ozone observations.
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.
New research indicates that man-made clouds formed along shipping routes dissipate too quickly to provide insight into the cooling effect of naturally occuring marine clouds.
NIDIS, NOAA’s National Integrated Drought Information System, has launched a redesigned U.S. Drought Portal to better serve stakeholders, decisionmakers, the media, and the public.
A new, fine-scale modeling approach developed by NOAA and CIRES scientists now projects that there will still be enough high-elevation snow by the middle of the 21st Century to support - according to federal biologists - the denning habits of one iconic North American mountain-dweller, the wolverine.
Understanding the biologic contribution of CO2 to megacities' overall carbon emissions will be important for designing and evaluating mitigation strategies.
