"\"Content\" indicates a quantity per unit area. The \"content_of_X_in_atmosphere_layer\" refers to the vertical integral between two specified levels in the atmosphere. \"Layer\" means any layer with upper and lower boundaries that have constant values in some vertical coordinate. There must be a vertical coordinate variable indicating the extent of the layer(s). If the layers are model layers, the vertical coordinate can be model_level_number, but it is recommended to specify a physical coordinate (in a scalar or auxiliary coordinate variable) as well. For the mole content integrated from the surface to the top of the atmosphere, standard names including \"atmosphere_mole_content_of_X\" are used. The chemical formula for methane is CH4. Methane is a member of the group of hydrocarbons known as alkanes. There are standard names for the alkane group as well as for some of the individual species."@en . . "SDN:P07::AW3W63S6" . . .
