Hi all! I’m trying to find variables for the salt advection fluxes in MOM6. In MOM5, these seem to be salt_xflux_adv and salt_yflux_adv. In MOM6, I have found S_adx, S_adx_2d, S_ady, and S_ady_2d, which seem right, but I have also found S_advection_xy (tendency?). Does anyone who is more familiar with this have any insight into which terms I should use? For context, I am hoping to do a depth-integrated salt budget. Thanks!

S_adx and S_ady should work, they are equivalent to salt_xflux_adv and salt_yflux_adv in MOM5, tho they are salinity transports (psu m3 s-1). S_adx_2d and S_ady_2d are the vertical sum of the two first ones. S_advection_xy is the horizontal salt convergence tendency ( useful for salt budget, kg of salt m-2 s-1) . I.e, if you save the first 2 ones, you probably dont need the 2ds. If you need vertical salt “advection“ you might want to save SH_TENDENCY_VERT_REMAP too.
Edit: Notice that S_adx and S_ady are salinity transports instead of salt ones. So, if you dont care if the signal is zonal or meridional, then S_advection_xy should be best for a salt budget?
