This directory contains several scripts to provide 2D boundary data
for a ROMS run with open boundaries. It needs a parent grid and data
(from an previous run with ROMS).

Before executing 'make_r2r' you should run 'make_h'. 'make_h' smooths
the child topography to satisfy r-factor criteria and matches child
topography with parent topography at the boundaries. 'make_r2r' produces
a netcdf files with boundary information. You'll have to edit the beginning
of 'make_r2r' and 'make_h' to suply the correct information for parent and child
grids and data.


Possible issues:

- It's not very good with recognizing 360 degree modulus in longitude. You'll
  have to make sure that parent and child grids overlap.

- It works well with the version of ROMS at UCLA. No garantees for other versions.
  (in particular, check that zlevs3.m produces the z-values that correspond to your
  model)


let me know if there are problems.
