4      ==============================      ==============================
5    
6    o GGL90 (Gaspar's TKE mixed layer)
7      - add horizontal diffusion of TKE, requires exchanges in
8        do_fields_blocking_exchanges, horizontal diffusivity is zero by
9        default. In OPA there is no horizontal diffusion of TKE but the
10        mixing coefficients are computed from a horizontal average of TKE of
11        6 points or so. I think that diffusion has a little more physical
12        justification.
13      - clean up ggl90_calc in the hope of reducing memory usage (this hope
14        was in vain)
15      - mask tke-variable in ggl90_init
16    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
17    o fix biharmonic diffusion on CS-grid.
18    o more obcs stuff
19      - added obcs_external_fields_load as an alternative to the EXF-pkg option
20        for reading boundary values. This routine is called from
21        obcs_prescribe_read
22      - updated obcs_check
23    
24    checkpoint55c_post
25    o obcs stuff
26      - new runtime flags useOBCSprescribe, useOBCSbalance
27      - re-arranged obcs_calc
28      - moved exf_getobcs to obcs_prescibe_read
29        obcs_prescibe_read is called after ORLANSKI stuff
30        and independent of it (executable can contain all).
31      - updated obcs_check
32      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
33        These may be necessary only if tangential velocities are
34        prescribed at OB, not sure, needs testing.
35    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
36      which simplifies the calls and passes the ifc check-bounds test
37    
38    checkpoint55b_post
39    o add a 2D scalar, Z location, exchange_2 routine.
40    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
41      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
42      affects advect_cs results (for the wrong reason): update output.txt
43    o use a more standard discretization for biharmonic viscosity ;
44     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
45      affects results of dome set-up: update output.txt
46    o fix gad_advection.F (CubedSphere part), back to version 1.23
47    o fix bug in mom_vi_del2uv.F (CubedSphere part).
48    
49    checkpoint55a_post
50    o merged code to
51      * prescribe/read time-dependent open boundaries
52        (works in conjunction with exf, cal)
53      * sponge layer code for open boundaries
54      * each boundary N/S/E/W now has its own CPP option
55        (healthy for the adjoint)
56    
57    checkpoint55
58    o up-to-date adjoint of previous breaks
59      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
60      - global_ocean_ebm: adjoint still needs fix (TLM ok)
61      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
62      - carbon: * remove tr1-related adjoint verification
63                * add ptracer as control variable
64    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
65      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
66    
67  checkpoint54f_post  checkpoint54f_post
68  o in verification/carbin/ remove experiment related to  o in verification/carbin/ remove experiment related to
69    ALLOW_PASSIVE_TRACER (array tr1 etc)    ALLOW_PASSIVE_TRACER (array tr1 etc)
