A NOAA study published in the journal Nature demonstrates a profound effect of the Montreal Protocol: as levels of ozone-depleting chemicals controlled by the intenational treaty declined, a poleward shift of summertime circulation patterns in the Southern Hemisphere halted.
Picture a calm, sunny day at a tropical beach. You look out at the ocean and in the distance a flotilla of small white clouds sails close to the waves. It’s ideal weather and typical of many days in the tropical Atlantic. However, scientists don’t fully understand how these ubiquitous clouds (a type of “shallow convective cloud”) form and impact the ocean, and it represents one of the largest uncertainties in predicting climate change.
An expedition to the central Arctic will give scientists the first opportunity to study the dramatic changes sweeping across the top of the world for an entire year.
A sooty cloud generated by a 2017 firestorm provided an ideal opportunity for researchers to test a climate model that simulated the lifetime of that soot in the stratosphere.
Findings could help improve air quality in cities across the U.S. West.
For scientists at NOAA, Earth Day — and every other day of the year — is about getting to the bottom of some of the most pressing questions about the planet we call home: how it works, how it’s changing, and how humans are affecting it.
New research on wind behavior in complex terrain, led by NOAA and the U.S. Department of Energy, will improve forecasts for wind energy firms by 15-25 percent, and improve wind forecasts for the entire country.
The University of Colorado has been awarded funding for development of an improved global map of smoke, dust and other aerosol particles.
