The hot and dry Santa Ana winds are associated with many of Southern California’s destructive wildfires, and even take the blame for tense, ugly moods. Now, NOAA researchers have found that on occasion the winds have an accomplice in contributing to California’s wildfires: atmospheric events known as stratospheric intrusions, which bring extremely dry air from the upper atmosphere down to the surface.
A perspective from NOAA and NASA scientists published online on January 29, 2014 in Nature Climate Change addresses a key question surrounding proposals to engineer the Earth’s climate to increase the planet’s reflection of sunlight to counteract climate warming: Could we measure manmade increases in reflectivity?
Scientists at the NOAA Cooperative Institute for Research in the Atmosphere at Colorado State University caught a rare image Friday -- a meteor exploding over Russia.
Scientists today unveiled unprecedented snapshots of Earth at night. Global composite images, constructed from cloud-free nighttime images from the new NOAA-NASA Suomi NPP satellite, were showcased at the American Geophysical Union’s annual meeting in San Francisco.
Warmer air temperatures high above the Antarctic led to the second smallest seasonal ozone hole in 20 years, according to NOAA and NASA satellite measurements
NOAA researchers will be using several innovative tools, techniques, and research results during the 2012 hurricane season to continue to improve hurricane forecasting. Read our 2012 hurricane research news briefs to learn more.
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.
