[MITgcm-support] C grid and pressure

[苗春葆]

Hi, Jody
   Thanks for providing the formula of calculating pressure anomaly.
    I have been confused by this problem for a while.
    Recently I found that  the meaning of PH found in the output file migh depend on the equation of state (EOS) used.
   If the linear EOS is used,  rhoConst*PH(i,j,k) is generally equal to the one obtained by integrating density anomaly, with the difference smaller than 10%.
   But if MDJWF is used, rhoConst*PH(i,j,k) is roughly 1000 times of the one obtained by integrating density anomaly.
   Is there anything wrong?  

Thanks.
