. "SDN:P07::CF12N635" . "The phrase \"tendency_of_X\" means derivative of X with respect to time. \"Content\" indicates a quantity per unit area. The \"atmosphere content\" of a quantity refers to the vertical integral from the surface to the top of the atmosphere. For the content between specified levels in the atmosphere, standard names including content_of_atmosphere_layer are used. The specification of a physical process by the phrase \"due_to_\" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. \"Emission\" means emission from a primary source located anywhere within the atmosphere, including at the lower boundary (i.e. earth's surface). \"Emission\" is a process entirely distinct from \"re-emission\" which is used in some standard names. The chemical formula for HCFC142b is CH3CClF2. The IUPAC name for HCFC142b is 1-chloro-1,1-difluoroethane."@en . . "SDN:P07::CF12N635" . . . "false" . "2018-12-17 17:17:12.0" . "2" . "2" .
