Hi,
Below are a few quantities that I'd like to define standard_name values for.
Both the
structure of the names, and the elements in the descriptions are taken from
existing
standard_name values. Point of contention may be the definition of water vapor
(not
all quantities in the list define what they mean with water vapor). A new
compound is
semiheavy water (HDO).
The canonical unit for all of these quantities is "mol m-2".
atmosphere_mole_content_of_carbon_monoxide
"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 construction
"atmosphere_mole_content_of_X" means the vertically integrated number of moles
of X
above a unit area. The chemical formula for carbon monoxide is CO.
atmosphere_mole_content_of_water_vapor
"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 construction
"atmosphere_mole_content_of_X" means the vertically integrated number of moles
of X
above a unit area. The atmosphere content only concerns water vapor as opposed
to
liquid water, i.e. water vapor that can be observed by optical spectroscopic
methods.
The chemical formula for water is H2O

Semiheavy water is water where one of the hydrogen atom has been replaced by
deuterium. The chemical formula for semiheavy water is HDO.
atmosphere_mole_content_of_methane
"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 construction
"atmosphere_mole_content_of_X" means the vertically integrated number of moles
of X
above a unit area. The chemical formula for methane is CH4.
In addition to the above:
mole_content_of_methane_in_atmosphere_layer
"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 ozone is CH4.
(compare to mole_content_of_ozone_in_atmosphere_layer. N.B. Dobson units is not a
common unit for other species ;-))
Similar:
mole_content_of_carbon_monoxide_in_atmosphere_layer
"Content" indicates a quantity per unit area. The

specified levels in the atmosphere. "Layer" means any layer with upper and lower
