8.  creation summary:
   1. Created monthly PHC2 T & S fields on tx0.1v2 grid using
    /fis/cgd/oce/bates/POP_grids/tx0.1v2/lev2grid.csh
    
    The vertical grid file 
   /fis/cgd/cseg/csm/collections/ccsm4_0_rel05/models/ocn/pop2/input_templates/tx0.1v2_vert_grid
    had only 2 columns with the first column being layer thickness and the second a dummy column of
    ones. Previous versions of $GRID_vert_grid have 3 columns. Keith Lindsay's regrid.F90 program
    assumes the grid file has three columns. I created a new vertical grid file with a third column 
    of ones. The file is called tx0.1v2_vert_grid_3col and the program to write it rewrite_vert_grid.f90.
    Both are found in /fis/cgd/oce/bates/POP_grids/tx0.1v2. This new vert_grid file is used in lev2grid.csh.
    
    Additionally, the regrid_extendz tool (by Keith Lindsay) was used rather than the default regrid 
    tool (regrid_normal). The model levels extend to deeper depths than the observations. The regrid_extendz 
    will copy the deepest depth from observations to use for any deeper model depths. The default regrid tool
    will ignore these levels and output a file with fewer levels in z.

   2. Created shf_20100318.ieeer8 using
    /fis01/cgd/oce/bates/POP_grids/tx0.1v2/forcing/remap_T62_to_tx0.1v2_shf.run
 
    This used the T62 to tx0.1v2 bilinear mapping file found at
    /fis/cgd/cseg/csm/inputdata/cpl/cpl6/map_T62_to_tx0.1v2_bilin_da_090220.nc
    
    AND
    
    the monthly atmospheric netcdf fields referenced below.
    
    NOTE: Previous output from this script yielded a file with 5 variables; however, according to 
    Steve Yeager, only the first is used by the model. Because this grid has such high resolution, 
    this program was not able to write the data (it would crash), so I changed line 77 in the code 
    from 'iv=1,5' to 'iv=1,1' so that it only writes out the first variable (which is SST from Levitus).
    Thus, the resulting file (shf_20100318.ieeer8) contains only SST.
    
    
9.  derived from:

    PHC2_TEMP_tx0.1v2.nc
    PHC2_SALT_tx0.1v2.nc

    (The above are regridded versions (using lev2grid.csh) of 
    	/HECHT/POLES/PHC2_TEMP.nc
    	/HECHT/POLES/PHC2_SALT.nc)

    AND

    monthly t62 85-88 atmospheric netcdf fields stored at
    /KAUFF/csm/data/ocn_force/data_orig.tar
    (see /gpfs/proj2/fis/cgd/cseg/csm/inputdata/ocn/pop/gx1v3/forcing/shf_mm_all_85-88_20010308.readme)
