4 Some tools (matlab scripts for now) specific to the Cubed-Sphere grid :
5
6 split_C_cub.m :: split a 2d,3d global CS-field into 6 faces ;
7 apply to cell-centered CS-field ; extend the face array by
8 adding 1 row & 1 column (like the exchanges)
9 split_Z_cub.m :: split a 2d,3d global CS-field into 6 faces ;
10 apply to cell-corner CS-field ; extend the face array by
11 adding 1 row & 1 column (like the exchanges)
12 split_UV_cub.m :: split the 2 C-grid components of a vector
13 (2d,3d global CS-field) into 6 faces ; extend the face array
14 by adding 1 row or 1 column (like the exchanges)
15
16 cubeZ2latlon.m :: interpolate a CS-field to regular Lat-lon grid ;
17 similar to cube2latlon.m but apply to a field that is
18 located at the corner point of the C-grid cell.
19 (deal with the 2 "missing corners")
20
21 calc_vort_cs.m :: compute vorticity (vertical component) on CS-grid
22 from MITgcm output velocity fields u,c (on C-grid);
23 Use the model discretization of vorticity.
24
25 the following scripts are reading a file that contains the orientation
26 of the local direction of the CS-grid relative to E-W,N-S direction.
27 file= proj_cs[]_2uEvN.bin :: cos & sin of rotation angle,
28 format:: real*8, big-endian, size=32x6x32 x2(cos+sin)
29 for standard cs32 grid, the corresponding file is:
30 verification/global_ocean.cs32x15/input/proj_cs32_2uEvN.bin
31
32 rotate_csAg_EN.m :: Rotate cell centered (A-grid) U,V vector components
33 of CS-grid to East,North directions. works for 2D or 3D vector.
34
35 rotate_csCg_EN.m :: Rotate MITgcm C-grid U,V vector components of CS-grid
36 to East,North directions. done in 2 steps: 1rst compute the average
37 at the cell-center and then rotate the vector.
38
39 uvLatLon2cube.m :: interpolate a 2 components vector field U,V (on A-grid)
40 to the MITgcm CS-grid (C-grid).
41
42 More in dir bk_line:
43 Scripts that generate "broken-lines" (used to compute Meridional Transport
44 stream-function and vertically integrated horizontal stream-function)
45 + a README file + an example for each one.
