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\". \"Brox\" describes a family of chemical species consisting of inorganic bromine compounds with the exception of hydrogen bromide (HBr) and bromine nitrate (BrONO2). The phrase \"expressed_as\" is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A. \"Brox\" is the term used in standard names for all species belonging to the family that are represented within a given model. The list of individual species that are included in a quantity with a group chemical standard name can vary between models. Where possible, the data variable should be accompanied by a complete description of the species represented, for example, by using a comment attribute. \"Inorganic bromine\", sometimes referred to as Bry, describes a family of chemical species which result from the degradation of source gases containing bromine (halons, methyl bromide, VSLS) and natural inorganic bromine sources such as volcanoes, sea salt and other aerosols. Standard names that use the term \"inorganic_bromine\" are used for quantities that contain all inorganic bromine species including HCl and ClONO2."@en . . . . . . . . . .
