Dear all,
I realize now that my last request for addition to the reference table
is not quite right. I have mixed up the already existing name for heat
content and the new one that will be added as alias to the next release
with the change to have more homogeneous names for integral quantities.
So my request should be for the name
*integral_wrt_depth_of_sea_water_temperature_expressed_as_heat_content
*with no change on the definition (based on the definition of the
existing name
integral_wrt_depth_of_sea_water_potential_temperature_expressed_as_heat_content)
The phrase "integral_wrt_X_of_Y" means int Y dX. The data variable
should have an axis for X specifying the limits of the integral as
bounds. "wrt" means with respect to. "expressed_as_heat_content" means
that this quantity is calculated as the (assumed constant) specific heat
capacity times density of sea water multiplied by the integral, over the
specified layer of the ocean, of the sea water temperature wrt depth.
"Content" indicates a quantity per unit area. Depth is the vertical
distance below the surface. Sea water temperature is the in situ
temperature of the sea water.*/
/*Unit**J m-2*/
/*In a similar way, I would like to request the addition of the
following name:
(based on the definition of the name
tendency_of_sea_water_potential_temperature_expressed_as_heat_content)
*tendency_of_sea_water_temperature_expressed_as_heat_content
*Content indicates a quantity per unit area. The phrase "tendency_of_X"
means derivative of X with respect to time. This tendency encompasses
all processes that impact on the time changes for the heat content
within a grid cell. The phrase "expressed_as_heat_content" means that
this quantity is calculated as the specific heat capacity times density
of sea water multiplied by the temperature of the sea water in the grid
cell. Sea water temperature is the in situ temperature of the sea water.*
*Unit W m-2*
*
On another matter, is there a set date for the next table release? Any
chance that my proposal from July 11th on "sea_binary_mask" can be
included in it?

I think these names (35 in total) are all very close to agreement and if possible I'd like to add them at the next standard name table update. Please could you have a look through the details below (I'm afraid there are a lot of them!) and let me know what you think. In particular, please can you check that you are happy with the definitions - I still have one or two questions about these - and also my suggestion to add the word 'eddy' in names 3q - 3v in the list below.

Therefore, I think the name is fine as it is. The complete definition, including that of sea_water_salinity would then be:
>> 'The salinity at the sea floor is that adjacent to the ocean bottom, which would be the deepest grid cell in an ocean model. Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term 'salinity' is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966), sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 to the present day), sea_water_absolute_salinity, S_A, sea_water_preformed_salinity, S_*, and sea_water_reference_salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually
based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows S_P = (S_K - 0.03) * (1.80655 / 1.805) and S_P = S_C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_water_salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_water_practical_salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. Practical salinity units are dimensionless. The unit "parts per thousand" was used for sea_water_knudsen_salinity and sea_water_cox_salinity.'
