| description | Mole fraction is used in the construction "mole_fraction_of_X_in_Y", where X is a material constituent of Y. A chemical species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". "Artificial tracer" means a passive atmospheric tracer that is used to study atmospheric transport and deposition. To specify the length of the tracer lifetime in the atmosphere, a scalar coordinate variable with the standard name of tracer_lifetime should be used. |
