Most winter precipitation starts out as snow, since it’s usually cold enough at the top layer of the cloud to create ...

Airplanes form invisible ice clouds that trap heat. Study explains why contrails matter and how aviation warming has been ...

Clouds form when water vapor – an invisible gas in the atmosphere – sticks to tiny floating particles, such as dust, and turns into liquid water droplets or ice crystals. In a newly published study, ...

Jackson, R., J. R. French, D. C. Leon, D. M. Plummer, S. Lasher-Trapp, A. M. Blyth, and A. Korolev, 2018: Observations of the microphysical evolution of convective ...

A new satellite has launched into orbit with the mission to clear up our understanding of how clouds and aerosols influence Earth's changing climate. Climate models have already done quite well in ...

Atmospheric scientists have reported a new and potentially important mechanism by which chemical emissions from ocean phytoplankton may influence the formation of clouds that reflect sunlight away ...

Scientists have spotted microplastics, tiny pieces of plastic smaller than 5 millimeters, in some of the most pristine environments on Earth, from the depths of the Mariana Trench to the snow on Mt.

Much of what we know about detailed cloud properties such as cloud hydrometeor size, shape, phase, and concentration, are derived from in situ measurements made on board instrumented aircraft. However ...
