"tendency_of_atmosphere_mass_content_of_terpenes_due_to_emission_from_forest_fires"@en . "\"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 mass is the total mass of the molecules. 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. Terpenes are hydrocarbons, that is, they contain only hydrogen and carbon combined in the general proportions (C5H8)n where n is an integer greater than on equal to one. The term \"terpenes\" is used in standard names to describe the group of chemical species having this common structure that are represented within a given model. The list of individual species that are included in a quantity having 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. Standard names exist for some individual terpene species, e.g., isoprene and limonene. The \"forest fires\" sector comprises the burning (natural and human-induced) of living or dead vegetation in forests. \"Forest fires\" is the term used in standard names to describe a collection of emission sources. A variable which has this value for the standard_name attribute should be accompanied by a comment attribute which lists the source categories and provides a reference to the categorization scheme, for example, \"IPCC (Intergovernmental Panel on Climate Change) source category 5 as defined in the 2006 IPCC guidelines for national greenhouse gas inventories\"."@en .
