5      ==============================      ==============================
6    
7    o exch2 adjoint
8      First set of changes:
9      - add exch2 hand-written adjoint templates
10      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
11        This will require cleanup in pkg/autodiff/*.F
12        (changed routines currently kept separate in verif. code/)
13      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
14        that used to hide exch2 or cubed-sphere specific code
15        (commented via 'cph-exch2')
16    
17    checkpoint59e
18    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
19      for B-grid vector (not yet tested) and C-grid vector (<- only used
20      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
21    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
22      (#ifdef ALLOW_SALT_PLUME)
23    o gather_2d/scatter_2d: removed halo regions
24    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
25      scheme and the corresponding test case (under front_relax dir). For now,
26      only available with Skew-flux form and not yet tested in realistic set-up.
27      adjoint: store directives updated, but gradient checks deteriorated,
28      so maybe GM/Redi adjoint is now broken.
29    o seaice adjoint
30      * add AREA, HEFF, HSNOW as control variable
31        (should not change lab_sea results)
32      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
33    o pkg/seaice:
34      * added computation of saltFlux in seaice_growth;
35        For time being, sea ice salinity is assumed constant
36        contribution of snow flooding to freshening of sea ice is neglected.
37        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
38        defaults to 0.0 in order to maintain backward compatibility.
39        Typical values for SEAICE_salinity are 4 to 10 g/kg.
40      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
41      * added SEAICE_availHeatFrac, which specifies fraction of surface level
42        heat content used to melt or grow ice
43      * commented out cap of HICE: it helps keep ice thinner
44      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
45      * applied OBCS T/S mask to HEFFM sea ice mask
46    
47    checkpoint59d
48    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
49     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
50     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
51    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
52     and change default value of parameter "GM_Small_Number";
53     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
54       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
55       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
56    o pkg/ecco: cost function when applying pkg/smooth to controls
57    o pkg/ctrl: add forcingPrecond run time parameter
58    o pkg/seaice:
59     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
60     - fix bug in metric terms of u-equation in LSR solver (implicit part),
61       changes verification/lab_sea
62     - rearrange implicit part of u-equation in LSR solver to make it easier to
63       read, understand, and debug. This causes changes at the truncation level.
64     - fix (serious) bug in the boundary conditions (sign error in the implicit
65       part) of the LSR solver. Changes all LSR results.
66     - fixed problem with HSNOW initialization to avoid thick snow when AREA
67       is initilized with small values - does not change lab_sea results.
68     - added HsnowFile initialization capability
69    o pkg/smooth: addition to model/src and pkg/ctrl so allow
70     initialization of pkg/smooth and application to control vector
71    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
72    o dependencies: pkg/profiles requires pkg/cal
73    o pkg/profiles:
74     - added option ALLOW_PROFILES_GENERICGRID
75         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
76         that interpolation information (grid points and coefficients) is provided
77         within the netcdf input files.
78         -> sample matlab scripts can be found in MITgcm_contrib/gael
79         that allow you to prepare netcdf input files.
80     - also modified: cleaner include statements, cleaner error print statements,
81       cleaner stops when error, and more tests of the netcdf input files consistency.
82    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
83    o pkg/seaice:
84     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
85       requires a new routine: seaice_diagnostics_fill.F
86     - make sure that seaice does not move if not forced (pressure replacement
87       method, Hibler and Ip, 1995), changes results
88     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
89     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
90       It is turned off by default (=-1.), because it changes the results.
91     - make it possible to read AREA from a file, too.
92    
93    checkpoint59c
94    o add S/R and diagnostics for oceanic mixed-layer depth
95    o move GMRedi call after all vertical mixing schemes (including KPP)
96    o pkg/thsice:
97     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
98      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
99  o pkg/obcs:  o pkg/obcs:
100   - bug fix for balance code   - bug fix for balance code
101  o pkg/seaice:  o pkg/seaice:

104        to SEAICE_elasticParm
105      - make lsr boundary conditions free slip (by default), changes result
106    - add code for no slip boundary conditions for lsr    - add code for no slip boundary conditions for lsr
107    - set minimum of zeta to zero (and not 4e8) (changes results)    - set minimum of zeta to zero (and not 4e8) (changes results)

120    o adjoint:
121      Re-organized adjoint checkpointing according to Matt Mazloff
122      (but with modifs/completions/cleanups)
123      Storing is now bundled into large arrays to optimized I/O
124      (and second step in cleanup of the_main_loop)
