Atmospheric turbulence may promote cloud droplet formation

Clouds form when water vapor in moist packets of air condenses onto atmospheric aerosols, such as particles of dust. The transition from dry particle to liquid water droplet is known as activation. The threshold for activation ...

Air pollution levels depend on drizzle rates

Scientists from Lawrence Livermore National Laboratory (LLNL), Scripps Institution of Oceanography and international collaborators have shown that an improved representation of drizzle rates leads to more pollution in the ...

NOAA-NASA Suomi NPP captures fires and aerosols across America

On Sep. 07, 2020, NOAA/NASA's Suomi NPP satellite provided two different views of how fires are affecting the U.S. A true-color image of the United States shows a blanket of smoke obscuring the surface from California to ...
