GRIB:

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. "tendency_of_X" means derivative of X with respect to time. "specific" means per unit mass. Specific humidity is the mass fraction of water vapor in (moist) air.

The phrase "tendency_of_X" means derivative of X with respect to time. "Content" indicates a quantity per unit area. The "atmosphere content" of a quantity refers to the vertical integral from the surface to the top of the atmosphere. For the content between specified levels in the atmosphere, standard names including "content_of_atmosphere_layer" are used. The chemical formula for water is H2O. 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. A variable with standard nametendency_of_atmosphere_mass_content_of_water_vapor_due_to_stratiform_cloud_condensation_and_deposition should contain only the processes of condensation (vapor to liquid) and deposition (vapor to ice) associated with the formation of stratiform clouds. Evaporation (liquid to vapor) and sublimation (ice to vapor) should not be included. In an atmosphere model, stratiform cloud is that produced by large-scale convergence (not the convection schemes). Deposition is the opposite of sublimation, i.e. it is the conversion of vapor into solid. Deposition in clouds is distinct from the processes of dry deposition and wet deposition of atmospheric aerosol particles, which are referred to in some standard names.
