Dear Jonathan,

I discussed this now with our modellers, and you are right, we are only interested in stokes drift induced by sea surface waves. So my proposal is then as follows:


sea_surface_wave_stokes_drift_x_velocity
sea_surface_wave_stokes_drift_y_velocity

units: m/s

description:
A velocity is a vector quantity. "x" indicates a vector component along the grid x-axis, positive with increasing x. The Stokes drift velocity is the average velocity when following a specific fluid parcel as it travels with the fluid flow. For instance, a particle floating at the free surface of water waves, experiences a net Stokes drift velocity in the direction of wave propagation.


Best wishes,

Heiko

I don't believe we have a standard name for that. I think it would be helpful
to add more specifics, such as sea_surface_wave (a phrase that appears in other
standard names), if that's applicable.

Best wishes

Jonathan

Subject: [CF-metadata] standard-name for stokes drift

Hi,

I'm looking for the standard-name for stokes drift for a wave-model:
http://en.wikipedia.org/wiki/Stokes_drift


It's defined by ECMWF as:
http://www.ecmwf.int/publications/manuals/d/gribapi/param/filter=grib1/order=paramId/order_type=asc/p=1/search=stokes/table=all/

I couldn't find any, and if this is really the case, I would propose
something like

stokes_drift_x_velocity
stokes_drift_y_velocity


units: m/s

Best regards,

Heiko
