Hello all,
We are working with some NEMO ocean model output data and would like to request 
new standard names for a number of the NEMO variables.


The list of these variables is below, in the form:      

NEMO variable name :

proposed CF Standard name

proposed definition. proposed units.

#----------------------------------------------------------------


sobpheig:

bottom_pressure_equivalent_height

Difference between the sea level height and the ocean steric height. (units = m)


somixhgt:

ocean_turbocline_depth

The turbocline depth is similar to the mixed layer depth but is estimated in 
models as the depth at which the vertical eddy diffusivity coefficient 
(resulting from the vertical physics alone) fall below a given value defined 
locally. (units = m)


vostheig:

ocean_steric_height

The steric measures the height by which a column of water with standard 
temperature T=0°C and salinity S=35.0 expands if its temperature and salinity 
are changed to the observed values (units = m)


vosthsal:

ocean_steric_thickness_due_to_salinity

Contribution of the salinity of the water column to the Ocean steric height. 
(units = m)


vosthtem:

ocean_steric_thickness_due_to_temperature

Contribution of the temperature of the water column to the Ocean steric height. 
(units = m)


vottrdmp:

temperature_profile_anomaly_correction

Correction term estimated as the deviation the local sea water potential 
temperature from an ocean model wrt to an observation-based climatology (eg 
World Ocean Database) multiplied by an user-specified relaxation coefficient. 
The relaxation coefficient depends on the timescale on which the correction is 
applied. (units = K/s)


vostrdmp:

practical_salinity_profile_anomaly_correction

Correction term estimated as the deviation the local sea water salinity from an 
ocean model wrt to an observation-based climatology (eg World
Ocean Database) multiplied by an user-specified relaxation coefficient. The 
relaxation coefficient depends on the timescale on which the correction is 
applied. (units = s-1)


sosal[300,700]:  

integral_of_sea_water_practical_salinity_wrt_depth (units = m )

This quantity is calculated as the integral, of the sea water salinty wrt 
depth, over the specified layer of the ocean from the surface to the level 
indicated by the vertical coordinate or scalar coordinate variable. 
"integral_of_Y_wrt_X" 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. 
"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. Depth is the vertical distance below the surface. 

Practical Salinity, S_P, is a determination of the salinity of sea water, based 
on its electrical conductance. The measured conductance, corrected for 
temperature and pressure, is compared to the conductance of a standard 
potassium chloride solution, producing a value on the Practical Salinity Scale 
of 1978 (PSS-78). This name should not be used to describe salinity 
observations made before 1978, or ones not based on conductance measurements. 
Conversion of Practical Salinity to other precisely defined salinity measures 
should use the appropriate formulas specified by TEOS-10. Other standard names 
for precisely defined salinity quantities are sea_water_absolute_salinity 
(S_A); sea_water_preformed_salinity (S_*), sea_water_reference_salinity (S_R); 
sea_water_cox_salinity (S_C), used for salinity observations between 1967 and 
1977; and sea_water_knudsen_salinity (S_K), used for salinity observations 
between 1901 and 1966. Salinity quantities that do not match any of the precise 
definitions should be given the more general standard name of 
sea_water_salinity. Reference: www.teos-10.org; Lewis, 1980 
doi:10.1109/JOE.1980.1145448.

integral_of_sea_water_practical_salinity_wrt_total_depth 

This quantity is calculated as the integral, of the sea water salinty, over of 
the ocean from the sea surface to the sea bed. "integral_of_Y_wrt_X" 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. "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
