"The surface called \"surface\" means the lower boundary of the atmosphere. \"Upward\" indicates a vector component which is positive when directed upward (negative downward). In accordance with common usage in geophysical disciplines, \"flux\" implies per unit area, called \"flux density\" in physics. The chemical formula for methane is CH4. 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. the surface of the earth). \"Emission\" is a process entirely distinct from \"re-emission\" which is used in some standard names. Termites belong to any of a group of cellulose-eating insects, the social system of which shows remarkable parallels with those of ants and bees, although it has evolved independently. The precise conditions under which termites produce and consume methane can vary between models."@en .
