[MITgcm-support] bathy file with Spherical Polar Grid

[Martin Losch]

Hi,

the bathymetry file needs to have value < 0 to be recognized as ocean depth. 
You need to specify the grid spacing in both cartesian (in meters) and spherical grid (in deg), please send your file "data".

Nothing else has been done. The MITgcm just runs normally, no err. But I find the values in  “Depth.***.***.data”are all set to 0. Then I set the ‘usingCartesianGrid’to .TRUE. ( usingSphericalPolarGrid=.FALSE. ) and then restart the model. This time the values in “Depth.***.***.data”files are right.
