| Definition | "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". The phrase "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" means the result of all chemical reactions within the medium (here, atmosphere) that produce a certain amount of the particular species. In chemistry, a "radical" is a highly reactive, and therefore short lived, species. The chemical formula for the hydroxyl radical is OH. The chemical formula for atomic_singlet_oxygen is O1D. The chemical formula for water vapor is H2O. Here, the production of hydroxyl radical is equal to 2k[O1D][H2O], i.e., 2 hydroxyl radicals are formed from the reaction of O1D with H2O. For models that do not have O1D as a species, the production of hydroxyl radical may be represented differently but the chemical production should take account of the hydroxyl yield. | ||
