Ice nucleus information


Ice nucleation mechanisms describe four modes that are responsible for the formation of primary ice crystals in the atmosphere.[clarification needed]

An ice nucleus, also known as an ice nucleating particle (INP), is a particle which acts as the nucleus for the formation of an ice crystal in the atmosphere.
