4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: a first HSALT time stepping equation has been checked in
8    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
9      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
10      without requiring DO-IF statements
11    o pkg/thsice:
12      use continuous power-law function for partition of energy between lateral
13      melting/freezing and thinning/thickening ; old code using step function
14      still available with #undef THSICE_FRACEN_POWERLAW
15      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
16    o testreport: change AD testing : check against results/output_adm.txt
17      using same scripts as for forward test.
18    
19    checkpoint59g
20    o adjoint testing: in preparation for changing testreport:
21      - output format: cost and grad written on separated lines
22      - ad output results in directory "results" (instead of "results_ad")
23    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
24    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
25    o pkg/ecco: allow user defined cost function contributions
26    o testreport:
27      Allow to choose (per experiment) the list of tested output variables
28       and the main variable (used to issue a pass/FAIL ) ;
29      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
30      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
31      Also modify printing of summary:
32       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
33       b) echo the list of tested variables in the individual summary.txt of
34          each experiment.
35    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
36      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
37      (but still depend on the tile decompostion of the domain).
38    o pkg/seaice: change a discretization detail to make the B-grid code
39      "more symmetric". This change is likely to remove all "ridges/leads" that
40      where quasi-aligned with the grid in B-grid solutions. It may also be
41      the solution to the stress coupling issues with the B-grid.
42    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
43      remove .cvsignore from input dir. (since testreport no longer run here).
44    o pkg/thsice:
45     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
46     - fix reshaping of sea-ice just after advection:
47       melt all the ice only if ice-volume is too small.
48     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
49       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
50     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
51    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
52      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
53    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
54      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
55      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
56      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
57      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
58      -> update output.txt
59    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
60     this affects truncation error: -> update output.txt of exp:
61      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
62      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
63    
64    checkpoint59f
65    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
66    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
67      a bounded range (in forward mode)
68    o pkg/ecco, ctrl, autodiff and mom_common:
69     internal parameter controls, completements of implementations
70    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
71    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
72      (not seem any difference in testing results).
73    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
74       at face corners.
75    o pkg/generic_advdiff:
76     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
77      loop range indices for computing vertical advection tendency
78      and do the calculation in the interior only (no overlap) ;
79      for now, only implemented for SOM advection (to save CPU time).
80     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
81    o exch2 adjoint
82      First set of changes:
83      - add exch2 hand-written adjoint templates
84      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
85        This will require cleanup in pkg/autodiff/*.F
86        (changed routines currently kept separate in verif. code/)
87      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
88        that used to hide exch2 or cubed-sphere specific code
89        (commented via 'cph-exch2')
90    o pkg/seaice
91      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
92    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
93       output of global_ocean.cs32x15.thsice .
94    
95    checkpoint59e
96    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
97      for B-grid vector (not yet tested) and C-grid vector (<- only used
98      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
99    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
100      (#ifdef ALLOW_SALT_PLUME)
101    o gather_2d/scatter_2d: removed halo regions
102    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
103      scheme and the corresponding test case (under front_relax dir). For now,
104      only available with Skew-flux form and not yet tested in realistic set-up.
105      adjoint: store directives updated, but gradient checks deteriorated,
106      so maybe GM/Redi adjoint is now broken.
107    o seaice adjoint
108      * add AREA, HEFF, HSNOW as control variable
109        (should not change lab_sea results)
110      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
111    o pkg/seaice:
112      * added computation of saltFlux in seaice_growth;
113        For time being, sea ice salinity is assumed constant
114        contribution of snow flooding to freshening of sea ice is neglected.
115        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
116        defaults to 0.0 in order to maintain backward compatibility.
117        Typical values for SEAICE_salinity are 4 to 10 g/kg.
118      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
119      * added SEAICE_availHeatFrac, which specifies fraction of surface level
120        heat content used to melt or grow ice
121      * commented out cap of HICE: it helps keep ice thinner
122      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
123      * applied OBCS T/S mask to HEFFM sea ice mask
124    
125    checkpoint59d
126    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
127     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
128     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
129    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
130     and change default value of parameter "GM_Small_Number";
131     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
132       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
133       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
134    o pkg/ecco: cost function when applying pkg/smooth to controls
135    o pkg/ctrl: add forcingPrecond run time parameter
136  o pkg/seaice:  o pkg/seaice:
137   - 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
138   - 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),
