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 ...

The link between clouds and penguin poop is not an obvious one but it has important implications for climate change. New ...

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 ...

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 ...

Penguin poop provides ammonia for cloud formation in coastal Antarctica, potentially helping to mitigate the impacts of climate change in the region.

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 ...

To produce one of these hole punch clouds, something has to introduce the necessary cloud condensation nuclei for the supercooled water to form into ice crystals. The second these particles are ...
