tendency_of_atmosphere_moles_of_molecular_hydrogen_due_to_chemical_production mol m-3 s-1 [MM3S] Mole concentration means number of moles per unit volume, also called "molarity", and is used in the construction "mole_concentration_of_X_in_Y", where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". "tendency_of_X" means derivative of X with respect to time. 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. "Chemical Production" refers to all chemical reactions within the medium (here, atmosphere) that produce a certain amount of a particular species from the medium. The chemical formula for molecular hydrogen is H2.
