[MITgcm-support] interpolation

[Jane Jimeian]

we want to interpolate from a coarse grid to a finer grid and restart from
a  pickup file.  does anybody have a matlab script or a subroutine that does
this.  if not, can someone explain the structure of the pickup file?  we
think it is U,?,V,??,T,W,S,???,Eta,X,XX where ?, ??, ??? are 3-D fields that
we don't recognize and X, XX are 2-D field that apparently don't matter to
us.  help will be appreciated.
