[MITgcm-support] RE: kalpana

[Chris Hill]

Hi All,

The grid files ( call tileNNN.mitgrid ) already contain the XC and YC for an
overlap of one.
They a multirecord files with XC and YC as the first two records, the record
size should be 511x511.
Example code that reads them is in ini_curvilinear_grid.F
