However, little is known about their atmospheric abundance and ice nucleation efficiency, and their role in clouds and the climate system is poorly constrained 6. One biological particle type ...

"We show that volcanic ash particles can trigger ice cloud formation by acting as sites for ice nucleation." Clouds reflect sunlight and trap heat, and because they cover about 70% of Earth's ...

Something almost magical happens when you put a tray full of sloshing, liquid water into a freezer and it comes out later as a rigid, solid crystal of ice. Chemists at the University of Utah have ...

Volcanic ash from eruptions can reshape cirrus clouds, forming giant ice crystals and altering how Earth traps heat in the ...

Learn how ash from volcanic eruptions can alter ice content in clouds, influencing how Earth handles radiation.

Clouds form when water vapor—an invisible ... fragments’ surfaces to determine their molecular structure, since ice nucleation could depend on the microplastics’ surface chemistry.

By adjusting the models to match observed ice-to-liquid ratios, the researchers closed much of the gap between simulated and observed warming. The finding suggests that fine-scale cloud microphysics – ...

According to Molinero, the models atmospheric scientists use to predict cloud behavior don’t yet account for the nuances of ice nucleation. And it’s still unclear which particles are actually the most ...

liquid water can condense into nanosize crystals of water ice, which then gather on smoke particles in the Venusian atmosphere in a process called nucleation. From these cloud seeds, fully formed ...
