4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/exf: improve vectorization by moving if-statement out of loops
8    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
9    o testreport:
10      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
11        monitor & update offline_exf_seaice exp. output.
12      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
13    o pkg/seaice:
14      - bug fix in the evp solver: boundary conditions were affected be
15        masking of zMax/zMin (changes results)
16      - minor bug fix in boundary conditions in seaice_calc_strainrates
17        (changes results for no_slip)
18      - seaice_lsr.F: make interpolation of eta dependent on boundaries
19      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
20      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
21        stress formulation and no-slip boundary conditions
22    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
23      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
24    o pkg/seaice: a first HSALT time stepping equation has been checked in
25    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
26      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
27      without requiring DO-IF statements
28    o pkg/thsice:
29      use continuous power-law function for partition of energy between lateral
30      melting/freezing and thinning/thickening ; old code using step function
31      still available with #undef THSICE_FRACEN_POWERLAW
32      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
33    o testreport: change AD testing : check against results/output_adm.txt
34      using same scripts as for forward test.
35    
36    checkpoint59g
37    o adjoint testing: in preparation for changing testreport:
38      - output format: cost and grad written on separated lines
39      - ad output results in directory "results" (instead of "results_ad")
40    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
41    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
42    o pkg/ecco: allow user defined cost function contributions
43    o testreport:
44      Allow to choose (per experiment) the list of tested output variables
45       and the main variable (used to issue a pass/FAIL ) ;
46      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
47      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
48      Also modify printing of summary:
49       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
50       b) echo the list of tested variables in the individual summary.txt of
51          each experiment.
52    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
53      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
54      (but still depend on the tile decompostion of the domain).
55    o pkg/seaice: change a discretization detail to make the B-grid code
56      "more symmetric". This change is likely to remove all "ridges/leads" that
57      where quasi-aligned with the grid in B-grid solutions. It may also be
58      the solution to the stress coupling issues with the B-grid.
59    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
60      remove .cvsignore from input dir. (since testreport no longer run here).
61    o pkg/thsice:
62     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
63     - fix reshaping of sea-ice just after advection:
64       melt all the ice only if ice-volume is too small.
65     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
66       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
67     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
68    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
69      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
70    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
71      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
72      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
73      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
74      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
75      -> update output.txt
76    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
77     this affects truncation error: -> update output.txt of exp:
78      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
79      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
80    
81    checkpoint59f
82    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
83    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
84      a bounded range (in forward mode)
85    o pkg/ecco, ctrl, autodiff and mom_common:
86     internal parameter controls, completements of implementations
87    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
88    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
89      (not seem any difference in testing results).
90    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
91       at face corners.
92    o pkg/generic_advdiff:
93     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
94      loop range indices for computing vertical advection tendency
95      and do the calculation in the interior only (no overlap) ;
96      for now, only implemented for SOM advection (to save CPU time).
97     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
98    o exch2 adjoint
99      First set of changes:
100      - add exch2 hand-written adjoint templates
101      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
102        This will require cleanup in pkg/autodiff/*.F
103        (changed routines currently kept separate in verif. code/)
104      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
105        that used to hide exch2 or cubed-sphere specific code
106        (commented via 'cph-exch2')
107    o pkg/seaice
108      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
109    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
110       output of global_ocean.cs32x15.thsice .
111    
112    checkpoint59e
113    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
114      for B-grid vector (not yet tested) and C-grid vector (<- only used
115      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
116    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
117      (#ifdef ALLOW_SALT_PLUME)
118    o gather_2d/scatter_2d: removed halo regions
119  o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007  o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
