Karl, thank you for the prompt reply.

exactly that is why I proposed the name.
I constructed it similar to already existing standard names, for example:
"surface_snow_thickness_where_sea_ice
The surface called "surface" means the lower boundary of the atmosphere;
over sea areas this is taken to be mean sea level. Unless indicated, a
quantity is assumed to apply to the whole area of each horizontal grid
box. The qualifier where_type specifies instead that the quantity applies
only to the part of the grid box of the named type."
Regards,
Burkhardt
