bin directory has various scripts to generate climatologies for hycom - used for
sidewall nudging, surface nudging and initialization.

Procedure for generating relaxation assuming experiment number, 
blkdat.input and topography is already set.

1) Create horizontally interpolated fields (z_*.sh routines). Output is placed
   in phc or levitus directories ++
2) Create final climatology with relax.sh -  input is experiment (01.0) and 
   climatology to use (phc or levitus). Output is placed in directory 
   "experiment X 10"  for instance 010 if experiment is 01.0).
4) Create relaxation  - relax_rmu.sh (TODO:not finished)

And if you want
X) Try (!) to use plotting routines in plot and plot_save for illustration -
   this requires some manual labour. There is some info in the hycom user manual
   

Routines in bin directory:
------------- - ---------------------------------------------------------
z_levitus.sh  - interpolates levitus climatology horizontally,
                the fields are suitable for interpolation on 
                vertical model grid. input is KSIGMA (thref in
                blkdat.input). This routine depends on the grid
                but not on topography.
z_phc.sh      - Same routine, but uses phc climatology which is better
                in the Arctic.

relax.sh      - uses output from the two above. It reads blkdat.input 
                for an experiment to find levels to interpolate to in
                the vertical. It also depends on the topography of the 
                experiment (set in EXPT.src and looked up in the  
                topo/ directory). Input is experiment number (ex 01.0)

old_lev_nersc - Mainly for surface relaxation for "old" forcing option
                actually used by old nersc forcing functions. (TODO:needs cleanup)

relax_rmu.sh  - Sets up relaxation mask
blkdat.sh     - help routine used by relax_rmu.sh
