Files contributed by JM for computation of barotropic streamfunction on cs510.

1 dimitri 1.1 bathymetry file ETOPO2_510x6x510_ver5_filled.bin
2     for cs510 integrations was generated using mk_bathy3.m
3     followed by mk_bathy5.m
4    
5     Levitus initial T and S and monthly SSS files for
6     cs510 integrations were generated using mk_input.m
7    
8     These routines are hard-coded for running in
9     nireas:/home/dimitri/mitgcm/setups/cube/510
10     Contact menemenlis@jpl.nasa.gov for questions, etc.

15     Files contributed by Jean-Michel on 3/27/2007 and used for computation of
16     barotropic streamfunction:
17    
18     psiLine_N2S_cs510.mat
19     mk_psiLine_CS.m
20     use_psiLine.m
21     v_integrate.m

26     Hi Michael,
27    
28     I put the *.m files that I was using in:
29     http://mitgcm.org/~jmc/
30     (Dimitris: might put them on CVS server later on,
31     may be in MITgcm_contrib/high_res/matlab/something ?)
32    
33     "mk_psiLine_CS.m" is not really different from
34     MITgcm/utils/matlab/cs_grid/bk_line (except kgr=0)
35    
36     I added the psiLine_N2S_cs510.mat file (from matlab 7,
37     don't think it will work with matlab 6).
38    
39     v_intergrate.m (was part of use_psiLine.m) read 12
40     monthly mean + integrate vertical to get the
41     annual mean, vertically integrated transport.
42    
43     and use_psiLine.m is just computing the stream-function
44     + making a plot.
45    
46     I've just checked-in grph_CSz.m so that it works also for
47     CS-510 grid.
