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      - changed sponge layer relaxation parameter units for days to seconds
24      - turned off sponge layer by default
25    
26    checkpoint55c_post
27    o obcs stuff
28      - new runtime flags useOBCSprescribe, useOBCSbalance
29      - re-arranged obcs_calc
30      - moved exf_getobcs to obcs_prescibe_read
31        obcs_prescibe_read is called after ORLANSKI stuff
32        and independent of it (executable can contain all).
33      - updated obcs_check
34      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
35        These may be necessary only if tangential velocities are
36        prescribed at OB, not sure, needs testing.
37    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
38      which simplifies the calls and passes the ifc check-bounds test
39    
40    checkpoint55b_post
41    o add a 2D scalar, Z location, exchange_2 routine.
42    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
43      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
44      affects advect_cs results (for the wrong reason): update output.txt
45    o use a more standard discretization for biharmonic viscosity ;
46     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
47      affects results of dome set-up: update output.txt
48    o fix gad_advection.F (CubedSphere part), back to version 1.23
49    o fix bug in mom_vi_del2uv.F (CubedSphere part).
50    
51    checkpoint55a_post
52    o merged code to
53      * prescribe/read time-dependent open boundaries
54        (works in conjunction with exf, cal)
55      * sponge layer code for open boundaries
56      * each boundary N/S/E/W now has its own CPP option
57        (healthy for the adjoint)
58    
59    checkpoint55
60    o up-to-date adjoint of previous breaks
61      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
62      - global_ocean_ebm: adjoint still needs fix (TLM ok)
63      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
64      - carbon: * remove tr1-related adjoint verification
65                * add ptracer as control variable
66    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
67      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
68    
69  checkpoint54f_post  checkpoint54f_post
70  o in verification/carbin/ remove experiment related to  o in verification/carbin/ remove experiment related to
71    ALLOW_PASSIVE_TRACER (array tr1 etc)    ALLOW_PASSIVE_TRACER (array tr1 etc)
