[CF-metadata] Missing standard names related to ocean waves

[Fabrice Ardhuin]

Dear CF users,
I have been producing for a few years some "exotic" parameters that do 
not show up in the list of standard names. My data archive people would 
thus like to have some new standard names approved.

Here are the parameters and suggested standard names:

1. Directional spread (defined from the full spectrum, see Kuik et al. 
J. Phys. Oceanogr. 1988) :
_
_|_sea_surface_wave_directional_spread_from_first_moments 
<javascript:void(0)>_

|The wave directional spectrum can be written as a five dimensional 
function S(t,x,y,f,theta) where t is time, x and y are horizontal 
coordinates (such as longitude and latitude), f is frequency and theta 
is direction. S has the standard name 
sea_surface_wave_directional_variance_spectral_density. S can be 
multiplied by cos(theta) and integrated over direction to give a1= 
integral(S*cos(theta) dtheta), likewise b1=integral(S*sin(theta) 
dtheta). After defining m1=sqrt(a1^2+b1^2), the directional spread is 
then, in radians,  s1=sqrt(2*(1-m1)). This value is usually converted to 
degrees as s1=sqrt(2*(1-m1))*180/pi .

2 and 3: Surface Stokes drift vector:

|sea_surface_wave_Stokes_eastward_drift <javascript:void(0)>
|
|Drift induced by short surface gravity waves (wind waves and swell) in 
the east direction

||sea_surface_wave_Stokes_northward_drift <javascript:void(0)>
|
|Drift induced by short surface gravity waves (wind waves and swell) in 
the north direction

|
4 and 5: Wave-induced volume transport

|sea_surface_wave_Stokes_eastward_transport <javascript:void(0)>
|
|Volume transport induced by short surface gravity waves (wind waves and 
swell) in the east direction

||sea_surface_wave_Stokes_northward_transport <javascript:void(0)>
|
|Volume transport induced by short surface gravity waves (wind waves and 
swell) in the north direction
|

6 and 7: Surface slope moments

|sea_surface_wave_east_west_mean_square_slope <javascript:void(0)>

Mean square of the sea surface slopes in the east-west direction
|
|sea_surface_wave_north_south_mean_square_slope <javascript:void(0)>

Mean square of the sea surface slopes in the north-south direction


|
8. Wind to waves energy flux :

atmosphere_to_sea_surface_wave_energy_flux_per_unit_area

Flux of energy from the wind to waves per unit area of the sea surface.


9. waves to ocean energy flux :

sea_surface_wave_to_ocean_energy_flux_per_unit_area

Flux of energy from the the surface waves to the ocean turbulence per 
unit area of the sea surface.


10 and 11: Same thing for momentum components:

sea_surface_wave_to_ocean_eastward_momentum_flux_per_unit_area

Eastward momentum flux from the the surface waves to the ocean current 
per unit area of the sea surface.

sea_surface_wave_to_ocean_northward_momentum_flux_per_unit_area

Northward momentum flux from the the surface waves to the ocean current 
per unit area of the sea surface.




12 to 15: Sea bottom agitation parameters:

sea_surface_wave_root_mean_square_amplitude_of_bottom_velocity

Root mean square amplitude of bottom orbital velocity induced by surface 
gravity waves.


sea_surface_wave_bottom_velocity_mean_direction

Mean direction of bottom orbital velocity induced by surface gravity waves.


sea_surface_wave_root_mean_square_amplitude_of_bottom_displacement_magnitude

Magnitude of root mean square amplitude of bottom orbital displacements 
induced by surface gravity waves.


sea_surface_wave_bottom_displacement_mean_direction

Mean direction of bottom orbital displacement induced by surface gravity 
waves.



That's all for now.

Thanks,

Fabrice
