If 3D fields cannot be specified, then is it possible to provide a vector with the depth variation? I am interested in prescribing arbitrary fields, rather than a particular diffusivity parameterization scheme.

I don’t think so, you can only specify 3D fields of vertical diffusivies, afaik.

Don’t the normal diffusive flux diagnostics should contain this (DFxETr01, DFyETr01, DFrETr01, DFrITr01, etc.)?
