[MITgcm-support] help to determine the global index

[Hong Zhang]

Hi, there
I have problem trying to determine the global index of (I,J)
from tile index (i,j,bi,bj).
My gridding configuration is as follows:
     &           sNx =  24,
     &           sNy =  28,
     &           OLx =   3,
     &           OLy =   3,
     &           nSx =   1,
     &           nSy =   1,
     &           nPx =   4,
     &           nPy =   4,
For example I want to locate the global point (50,76).
How can I find this point?
I checked XC and YC, unfortunately they are not consistent with
global I,J because I use a rotated coordinate system.

thanks
