[MITgcm-support] Convert C32 to C64

[Nikole Lewis]

Everyone-
      I'd like to take the output parameters from a 32x32 tile
cubed-sphere run (say from a pick-up file) and use that as the initial
conditions for a higher resolution run (64x64 tiles).   Any ideas on
the right way to do this?

Thanks,
Nikole Lewis
