[MITgcm-support] ETA with making Boussinesq approximations

[连展]

OH!Im sorry.I have maked a mistake.I mean ETA in a model without Boussinesq approximations

  Hi,everyone,

      I am trying to study the change of ETA in a model with making Boussinesq approximations.I start from the example experiment "tutorial_global_oce_in_p". However,I find that the model output ETA in pressure coordinates in this experiment.Can I output the ETA in Z-coordinates diretly? 
      I translated the ETA from  pressure coordinates  to Z-coordinates by dividing rho（suferface layer）*g，and I found the result is very different from the result of experiment "tutorial_global_oce_latlon".Does "ETA" have the same meaning in this two experiment?How could I get the free-surface_r-anomaly(m) in a model with making Boussinesq approximations?

  Thanks!!

  lian
