4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
8      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
9    o pkg/seaice: a first HSALT time stepping equation has been checked in
10    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
11      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
12      without requiring DO-IF statements
13    o pkg/thsice:
14      use continuous power-law function for partition of energy between lateral
15      melting/freezing and thinning/thickening ; old code using step function
16      still available with #undef THSICE_FRACEN_POWERLAW
17      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
18    o testreport: change AD testing : check against results/output_adm.txt
19      using same scripts as for forward test.
20    
21    checkpoint59g
22    o adjoint testing: in preparation for changing testreport:
23      - output format: cost and grad written on separated lines
24      - ad output results in directory "results" (instead of "results_ad")
25    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
26    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
27    o pkg/ecco: allow user defined cost function contributions
28    o testreport:
29      Allow to choose (per experiment) the list of tested output variables
30       and the main variable (used to issue a pass/FAIL ) ;
31      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
32      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
33      Also modify printing of summary:
34       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
35       b) echo the list of tested variables in the individual summary.txt of
36          each experiment.
37    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
38      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
39      (but still depend on the tile decompostion of the domain).
40    o pkg/seaice: change a discretization detail to make the B-grid code
41      "more symmetric". This change is likely to remove all "ridges/leads" that
42      where quasi-aligned with the grid in B-grid solutions. It may also be
43      the solution to the stress coupling issues with the B-grid.
44    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
45      remove .cvsignore from input dir. (since testreport no longer run here).
46    o pkg/thsice:
47     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
48     - fix reshaping of sea-ice just after advection:
49       melt all the ice only if ice-volume is too small.
50     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
51       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
52     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
53    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
54      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
55    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
56      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
57      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
58      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
59      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
60      -> update output.txt
61    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
62     this affects truncation error: -> update output.txt of exp:
63      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
64      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.

67  o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)  o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
68  o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in  o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
