MOM_input of a global MOM6-SIS2 simulation using ICs from other z-coordinate model results

[egiarolla]

I've been trying to run a global MOM6-SIS2 experiment but, instead of beginning from that GOLD_SIS_IC.nc file, I've used the fields of a Mercator product run, remapped to my grid. The model runs without problems, but the results are not quite good. I see some areas with higher currents speed and lower SSTs than usual.

I wonder whether I've been doing everything right while setting the parameters in MOM_input, to correctly read the IC file in Z coordinates and define all layers and thicknesses.

Has anyone already done something similar? If so, could you please share information about the MOM_input variables settings?

I'll show examples of my concerns here.

For instance, If I define
INIT_LAYERS_FROM_Z_FILE = True
TEMP_SALT_Z_INIT_FILE = "some_file.nc" ! default = "temp_salt_z.nc"

are those setting above overriding that following one?:
TS_CONFIG = "file" ! A string that determines how the initial tempertures and salinities are
! specified for a new run:
