@iangrooms Just a quick note, I added hfibthermds to the native history file, which I assume is what you meant by hfidthermds.

[alperaltuntas]

@iangrooms, I added BS_coeff_h and switched to using cmor names for those fields you listed (via the already existing visc_flds list).

@iangrooms & @gustavo-marques, while at it, should I also switch to the CMOR equivalent names of the following fields listed in diag_table.yaml?:

Field in diag_table.yaml	CMOR equivalent	Used in list(s)
sst_global	tosga	surface_flds_monthly
sss_global	sosga	surface_flds_monthly
C_P	cpocean	static_flds
Rho_0	rhozero	static_flds
FrictWorkIntz	dispkexyfo	cmip7_native
diabatic_heat_tendency	opottempdiff	cmip7_z
diabatic_salt_tendency	osaltdiff	cmip7_z
Th_tendency	opottemptend	cmip7_z
Sh_tendency	osalttend	cmip7_z

@alperaltuntas yes, I think it would be good to switch the fields you mentioned to CMOR now, rather than having to rename them after the fact.

[gustavo-marques]

I agree, thank you for pointing out these fields.

[alperaltuntas]

@iangrooms @gustavo-marques I made the all the changes, I think. This PR is ready for the next round of reviews.

[iangrooms]

Looks good to me. Thanks!
