8  0) Download the Circum-Antarctic Tide (CATS) Solution (Padman et al. 2002)  0) Download the Circum-Antarctic Tide (CATS) Solution (Padman et al. 2002)
9     from Earth and Space Research, http://www.esr.org.     from Earth and Space Research,   http://www.esr.org/~padman/cats2008b/
10     Modify CAT directory in test_tide_bc.m     Modify CATS directory in test_tide_bc.m  
11       Download the TMD2.03 software for extracting the tidal solution from
12       http://www.esr.org.
13       Modifications  are needed in the original /TMD2.03/tmd_extract_HC.m in order
14       to have the correct path of tidal solution as shown in the sample_tmd_extract_HC.m.
15    
16  1) use create_bc_grid.m (test_bc_grid.m) to generate bc grid files.  
17    1) use create_bc_grid.m (called by test_bc_grid.m) to generate bc grid files.
18     create_bc_grid.m will generate files with names like     create_bc_grid.m will generate files with names like
19     bdry_grid_[snwe].mat for south, north, west, and east boundary.       bdry_grid_[snwe].mat for south, north, west, and east boundary.  
20     This script needs a directory path for MITgcm domain related files,     This script needs a directory path for MITgcm domain related files,
21     especially YC.data, XC.data, hFacC.data, AngleCS.data, AngleSN.data.     specifically  YC.data, XC.data, hFacC.data, AngleCS.data, AngleSN.data.

24     create_tide_bc_4bdry.m     create_tide_bc_second.m
25     or dummy tidal bc files (zero amplitde and phase) for land boundary     or dummy tidal bc files (zero amplitude and phase, tide_bc_empty.m)
26     if there is such a need.     for land boundary if there is such a need.
27    
28     create_tide_bc_second.m will generate tidal bounday files with names     create_tide_bc_second.m will generate tidal boundary files with names
29     like OB[SNWE]{am ph}.seaice_obcs.       like OB[SNWE]{am ph}.seaice_obcs.  
30     The tidal current and phase will be used in  obcs_add_tides.F.         The tidal current and phase will be used in  obcs_add_tides.F.
