Dear Roy,
I think it's because of the fact that in the upper layer (10m or so) we may
have all four of them :
1) surface_eastward_sea_water_velocity and
surface_northward_sea_water_velocity for water AND ice
This is already a standard name with the definition that >"Water" means water
in
Dear Ute,
There is a precedent in CF for not giving separate Standard Names to a single
geophysical variable solely on the basis of its spatial distribution, the
classic example being air temperature where the meteorological standard
measurement '2m air temperature' has not been given its own
