[MITgcm-support] potential density

[Bruno Deremble]

Good morning,

In do_oceanic_phys, are sigmax and sigmay the gradients of potential density (as stated in the manual in the gmredi section)? I ask this because they are computed using 'rhoinsitu' which I presume is the in situ density and not the potential density.

in the diagnostic package WRHOMASS is associated to Vertical Transport of Potential Density whereas URHOMASS and VRHOMASS are the horizontal transport of density. Is it correct in both cases?

thank you
