Per NOAA, water molecules need something to attach to in order to condense — these objects are cloud condensation nuclei. Cloud condensation nuclei can be various things, from wildfire smoke to ...

Can penguin poop really slow down global warming? A new study says that the unassuming penguin guano can reduce the effects ...

Clouds are made up of water droplets or ice crystals bound to particles known as condensation or ice nuclei in the atmosphere. Cloud seeding puts artificial nuclei into the air using silver ...

The subsequent growth of these particles is thought to contribute approximately half of the global number of cloud condensation nuclei (CCN), substantially affecting cloud properties and Earth's ...

Atmospheric scientists like me call these tiny particles cloud condensation nuclei or CCN for short. These CCN are just dirt or dust particles that have been lifted by the wind and are floating ...

PROF. Barus has written more upon the subject of condensation nuclei than any other physicist. In the present memoir, as in those which have preceded it, he arrives at conclusions which are not in ...
