Term: ocean_turbocline_depth
Unit: m
Unit ref: ULAA
AMIP:
GRIB:
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.

AMIP:
GRIB:
The turbocline thickness is similar to the mixed layer thickness but is estimated in models as the thickness at which the vertical eddy diffusivity coefficient (resulting from the vertical physics alone) falls below a given value defined locally. A coordinate variable or scalar coordinate variable with standard name ocean_vertical_diffusivity should be specified to indicate the value of the coefficient that was used to calculate the turbocline thickness.

"Thickness" means the vertical extent of a layer. The turbocline thickness is similar to the mixed layer thickness but is estimated in models as the thickness at which the vertical eddy diffusivity coefficient (resulting from the vertical physics alone) falls below a given value defined locally. A coordinate variable or scalar coordinate variable with standard name ocean_vertical_diffusivity should be specified to indicate the value of the coefficient that was used to calculate the turbocline thickness.

GRIB:
"Thickness" means the vertical extent of a layer. The ocean mixed layer is the upper part of the ocean, regarded as being well-mixed. Diffusivity is also sometimes known as the coefficient of diffusion. Diffusion occurs as a result of a gradient in the spatial distribution of mass concentration, temperature or momentum. The diffusivity may be very different in the vertical and horizontal directions. The diffusivity threshold should be specified by associating a coordinate variable or scalar coordinate variable with the data variable and giving the coordinate variable a standard name of f a threshold is supplied, it should be specified by associating a coordinate variable or scalar coordinate variable with the data variable and giving the coordinate variable a standard name of ocean_vertical_diffusivity or, if appropriate, one of the standard names for vertical diffusivity relating to the specific model formulation.
