The column operates on the principle that the diffusion of water vapour in air is quicker than heat allowing a region in the center of the CCN column to be supersaturated when a vertical temperature gradient in is maintained.","keywords":"","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/3439/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/3440/?format=json"],"instrumentType":"instrument","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/23259/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/23258/?format=json"]}
