4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o adjoint testing: in preparation for changing testreport:
8      - output format: cost and grad written on separated lines
9      - ad output results in directory "results" (instead of "results_ad")
10    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
11    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
12    o pkg/ecco: allow user defined cost function contributions
13    o testreport:
14      Allow to choose (per experiment) the list of tested output variables
15       and the main variable (used to issue a pass/FAIL ) ;
16      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
17      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
18      Also modify printing of summary:
19       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
20       b) echo the list of tested variables in the individual summary.txt of
21          each experiment.
22    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
23      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
24      (but still depend on the tile decompostion of the domain).
25    o pkg/seaice: change a discretization detail to make the B-grid code
26      "more symmetric". This change is likely to remove all "ridges/leads" that
27      where quasi-aligned with the grid in B-grid solutions. It may also be
28      the solution to the stress coupling issues with the B-grid.
29    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
30      remove .cvsignore from input dir. (since testreport no longer run here).
31    o pkg/thsice:
32     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
33     - fix reshaping of sea-ice just after advection:
34       melt all the ice only if ice-volume is too small.
35     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
36       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
37     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
38    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
39      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
40    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
41      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
42      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
43      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
44      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
45      -> update output.txt
46    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
47     this affects truncation error: -> update output.txt of exp:
48      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
49      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
50    
51    checkpoint59f
52    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
53    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
54      a bounded range (in forward mode)
55    o pkg/ecco, ctrl, autodiff and mom_common:
56     internal parameter controls, completements of implementations
57    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
58    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
59      (not seem any difference in testing results).
60    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
61       at face corners.
62    o pkg/generic_advdiff:
63     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
64      loop range indices for computing vertical advection tendency
65      and do the calculation in the interior only (no overlap) ;
66      for now, only implemented for SOM advection (to save CPU time).
67     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
68    o exch2 adjoint
69      First set of changes:
70      - add exch2 hand-written adjoint templates
71      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
72        This will require cleanup in pkg/autodiff/*.F
73        (changed routines currently kept separate in verif. code/)
74      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
75        that used to hide exch2 or cubed-sphere specific code
76        (commented via 'cph-exch2')
77    o pkg/seaice
78      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
79    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
80       output of global_ocean.cs32x15.thsice .
81    
82    checkpoint59e
83    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
84      for B-grid vector (not yet tested) and C-grid vector (<- only used
85      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
86    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
87      (#ifdef ALLOW_SALT_PLUME)
88    o gather_2d/scatter_2d: removed halo regions
89  o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007  o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
90    scheme and the corresponding test case (under front_relax dir). For now,    scheme and the corresponding test case (under front_relax dir). For now,
91    only available with Skew-flux form and not yet tested in realistic set-up.    only available with Skew-flux form and not yet tested in realistic set-up.
