Dear All,
looking at the discussion in this thread in conjunction with that in the
ECHAM5-hammoz thread there are a number of main points arising:
1) In this discussion agreement has been reached to change all names
following the pattern of:
[tendency_of_]moles_of_X_in_atmosphere|troposphere|middle_atmosphere
to
[tendency_of_]atmosphere|troposphere|middle_atmosphere_moles_of_X
where X is the name of a chemical species. Therefore, the following
aliases will be created in the standard name table:
moles_of_carbon_monoxide_in_atmosphere becomes
atmosphere_moles_of_carbon_monoxide
moles_of_carbon_tetrachloride_in_atmosphere becomes
atmosphere_moles_of_carbon_tetrachloride

2) Agreement has been reached that new 'local media' of in_cloud_water,
in_cloud_liquid_water and in_cloud_ice will be useful for describing
dissolved chemical species. I will add these to the list of acceptable
values in the 'Medium' section of the standard name guidelines.
3) Position of large-scale and local medium within the standard name.
Following on from the discussion of large-scale and local media (e.g.
'atmosphere' versus 'in_air') and their respective positions within the
standard name, Christiane has suggested that large-scale medium should
always appear as a prefix and local medium as a postfix. This is
consistent with existing atmosphere/ocean and in_air/in_sea_water
standard names (including the moles_of_X names when the change in (1) is
implemented). I propose therefore to amend the standard name guidelines
as follows
a) In the 'Qualifications' section, change the pattern for constructing
standard names from
[surface] [component] standard_name [at surface] [in medium] [due to
process] [assuming condition]
to
[surface] [component] [large-scale medium] standard_name [at surface]
[in local medium] [due to process] [assuming condition]
b) Add a new section entitled 'Large-scale medium' following the
existing 'Component' section:
Large-scale medium
The medium throughout which a quantity applies: atmosphere, troposphere,
stratosphere, mesosphere, thermosphere, middle_atmosphere, ocean.
c) Alter the title of the existing 'Medium' section to 'Local Medium'
and alter the wording as follows:
Local medium
The local medium or layer within which an intensive quantity applies:
in_air, in_atmosphere_boundary_layer, in_sea_ice, in_sea_water, in_soil,
in_soil_water, in_cloud_water, in_cloud_liquid_water, in_cloud_ice.
I would welcome any comments on the proposed changes.
4) Deprecate the use of 'atmosphere_layer' in standard names in favour
of using simply 'atmosphere' with a vertical coordinate and bounds
variable to indicate the extent of the layer. This point was raised
under the ECHAM5/Hammoz discussion.
N.B. This would not affect existing soil_layer, snow_layer and
atmosphere_boundary_layer names, all of which are intended to indicate a
physically distinct layer in its entirety, rather than a sub-division of
a larger medium.
Both Jonathan and Christiane seem to be in favour of the proposal to
deprecate atmosphere_layer. It would affect 31 atmosphere names and, by
extension, 4 ocean_layer names. As it affects more than just
atmospheric chemistry names I think this proposal should be discussed
more widely before a final decision is taken.
5) There is another general point worth mentioning here that arose (in a
telephone conversation) from the discussion of the CMIP5 ocean names
proposed by Stephen Griffies. Stephen has questioned whether some of
the existing standard names that employ the term 'ocean' should in fact
use 'sea_water'. I promised to raise this again as a discussion on the
mailing list in April. It seems that there is a need to review whether
all names using the terms 'ocean', 'atmosphere', 'in_sea_water',
'in_air', 'atmosphere_layer' and 'ocean_layer' are doing so in a
consistent manner and whether the advice in the Guidelines regarding the
use of all these terms is clear. I will raise points (4) and (5) again
in a general discussion of 'medium', rather than continuing under this
atmosphere only thread.
Best wishes,
Alison
