4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
8      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
9      without requiring DO-IF statements
10    
11    checkpoint59g
12    o adjoint testing: in preparation for changing testreport:
13      - output format: cost and grad written on separated lines
14      - ad output results in directory "results" (instead of "results_ad")
15    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
16    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
17    o pkg/ecco: allow user defined cost function contributions
18    o testreport:
19      Allow to choose (per experiment) the list of tested output variables
20       and the main variable (used to issue a pass/FAIL ) ;
21      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
22      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
23      Also modify printing of summary:
24       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
25       b) echo the list of tested variables in the individual summary.txt of
26          each experiment.
27    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
28      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
29      (but still depend on the tile decompostion of the domain).
30    o pkg/seaice: change a discretization detail to make the B-grid code
31      "more symmetric". This change is likely to remove all "ridges/leads" that
32      where quasi-aligned with the grid in B-grid solutions. It may also be
33      the solution to the stress coupling issues with the B-grid.
34    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
35      remove .cvsignore from input dir. (since testreport no longer run here).
36    o pkg/thsice:
37     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
38     - fix reshaping of sea-ice just after advection:
39       melt all the ice only if ice-volume is too small.
40     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
41       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
42     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
43    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
44      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
45    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
46      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
47      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
48      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
49      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
50      -> update output.txt
51    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
52     this affects truncation error: -> update output.txt of exp:
53      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
54      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
55    
56    checkpoint59f
57    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
58    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
59      a bounded range (in forward mode)
60    o pkg/ecco, ctrl, autodiff and mom_common:
61     internal parameter controls, completements of implementations
62    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
63    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
64      (not seem any difference in testing results).
65    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
66       at face corners.
67    o pkg/generic_advdiff:
68     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
69      loop range indices for computing vertical advection tendency
70      and do the calculation in the interior only (no overlap) ;
71      for now, only implemented for SOM advection (to save CPU time).
72     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
73    o exch2 adjoint
74      First set of changes:
75      - add exch2 hand-written adjoint templates
76      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
77        This will require cleanup in pkg/autodiff/*.F
78        (changed routines currently kept separate in verif. code/)
79      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
80        that used to hide exch2 or cubed-sphere specific code
81        (commented via 'cph-exch2')
82    o pkg/seaice
83      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
84    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
85       output of global_ocean.cs32x15.thsice .
86    
87    checkpoint59e
88    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
89      for B-grid vector (not yet tested) and C-grid vector (<- only used
90      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
91    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
92      (#ifdef ALLOW_SALT_PLUME)
93    o gather_2d/scatter_2d: removed halo regions
94    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
95      scheme and the corresponding test case (under front_relax dir). For now,
96      only available with Skew-flux form and not yet tested in realistic set-up.
97      adjoint: store directives updated, but gradient checks deteriorated,
98      so maybe GM/Redi adjoint is now broken.
99    o seaice adjoint
100      * add AREA, HEFF, HSNOW as control variable
101        (should not change lab_sea results)
102      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
103    o pkg/seaice:
104      * added computation of saltFlux in seaice_growth;
105        For time being, sea ice salinity is assumed constant
106        contribution of snow flooding to freshening of sea ice is neglected.
107        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
108        defaults to 0.0 in order to maintain backward compatibility.
109        Typical values for SEAICE_salinity are 4 to 10 g/kg.
110      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
111      * added SEAICE_availHeatFrac, which specifies fraction of surface level
112        heat content used to melt or grow ice
113      * commented out cap of HICE: it helps keep ice thinner
114      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
115      * applied OBCS T/S mask to HEFFM sea ice mask
116    
117    checkpoint59d
118    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
119     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
120     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
121    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
122     and change default value of parameter "GM_Small_Number";
123     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
124       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
125       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
126    o pkg/ecco: cost function when applying pkg/smooth to controls
127    o pkg/ctrl: add forcingPrecond run time parameter
128  o pkg/seaice:  o pkg/seaice:
129   - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code   - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
130   - fix bug in metric terms of u-equation in LSR solver (implicit part),   - fix bug in metric terms of u-equation in LSR solver (implicit part),
