4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o seaice adjoint
8      * add AREA, HEFF, HSNOW as control variable
9        (should not change lab_sea results)
10      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
11    
12    checkpoint59d
13    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
14     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
15     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
16    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
17     and change default value of parameter "GM_Small_Number";
18     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
19       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
20       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
21    o pkg/ecco: cost function when applying pkg/smooth to controls
22    o pkg/ctrl: add forcingPrecond run time parameter
23    o pkg/seaice:
24     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
25     - fix bug in metric terms of u-equation in LSR solver (implicit part),
26       changes verification/lab_sea
27     - rearrange implicit part of u-equation in LSR solver to make it easier to
28       read, understand, and debug. This causes changes at the truncation level.
29     - fix (serious) bug in the boundary conditions (sign error in the implicit
30       part) of the LSR solver. Changes all LSR results.
31     - fixed problem with HSNOW initialization to avoid thick snow when AREA
32       is initilized with small values - does not change lab_sea results.
33     - added HsnowFile initialization capability
34    o pkg/smooth: addition to model/src and pkg/ctrl so allow
35     initialization of pkg/smooth and application to control vector
36    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
37    o dependencies: pkg/profiles requires pkg/cal
38    o pkg/profiles:
39     - added option ALLOW_PROFILES_GENERICGRID
40         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
41         that interpolation information (grid points and coefficients) is provided
42         within the netcdf input files.
43         -> sample matlab scripts can be found in MITgcm_contrib/gael
44         that allow you to prepare netcdf input files.
45     - also modified: cleaner include statements, cleaner error print statements,
46       cleaner stops when error, and more tests of the netcdf input files consistency.
47    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
48    o pkg/seaice:
49     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
50       requires a new routine: seaice_diagnostics_fill.F
51     - make sure that seaice does not move if not forced (pressure replacement
52       method, Hibler and Ip, 1995), changes results
53     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
54     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
55       It is turned off by default (=-1.), because it changes the results.
56     - make it possible to read AREA from a file, too.
57    
58    checkpoint59c
59    o add S/R and diagnostics for oceanic mixed-layer depth
60    o move GMRedi call after all vertical mixing schemes (including KPP)
61    o pkg/thsice:
62     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
63      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
64  o pkg/obcs:  o pkg/obcs:
65   - bug fix for balance code   - bug fix for balance code
66  o pkg/seaice:  o pkg/seaice:
67    - allow values of SEAICE_elaticParm > 1    - allow values of SEAICE_elasticParm > 1
68    - make lsr boundary conditions free slip (by default)    - add new parameter SEAICE_evpTauRelax as an alternative
69        to SEAICE_elasticParm
70      - make lsr boundary conditions free slip (by default), changes result
71    - add code for no slip boundary conditions for lsr    - add code for no slip boundary conditions for lsr
72    - set minimum of zeta to zero (and not 4e8) (changes results)    - set minimum of zeta to zero (and not 4e8) (changes results)
73      - add a cap on AREA after advecting AREA if seaice_growth is not called
74  o change calculation of Visbeck K:  o change calculation of Visbeck K:
75    - no longer depend on tapering scheme; instead, compute slope (limited    - no longer depend on tapering scheme; instead, compute slope (limited
76      by GM_maxSlope). this is equivalent to what was comuted before with      by GM_maxSlope). this is equivalent to what was comuted before with
77      clipping or linear tappering.      clipping or linear tappering.

80      #ifdef OLD_VISBECK_CALC / #endif      #ifdef OLD_VISBECK_CALC / #endif
81      - update output of exp. ideal_2D_oce

83  o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and  o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
84    add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).    add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
85    o adjoint:
86      Re-organized adjoint checkpointing according to Matt Mazloff
87      (but with modifs/completions/cleanups)
88      Storing is now bundled into large arrays to optimized I/O
89      (and second step in cleanup of the_main_loop)

142    - growth vertically (and not laterally) if iceFrac == iceMaskMax    - growth vertically (and not laterally) if iceFrac == iceMaskMax
