4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
8      scheme and the corresponding test case (under front_relax dir). For now,
9      only available with Skew-flux form and not yet tested in realistic set-up.
10    o seaice adjoint
11      * add AREA, HEFF, HSNOW as control variable
12        (should not change lab_sea results)
13      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
14    
15    checkpoint59d
16    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
17     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
18     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
19    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
20     and change default value of parameter "GM_Small_Number";
21     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
22       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
23       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
24    o pkg/ecco: cost function when applying pkg/smooth to controls
25    o pkg/ctrl: add forcingPrecond run time parameter
26    o pkg/seaice:
27     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
28     - fix bug in metric terms of u-equation in LSR solver (implicit part),
29       changes verification/lab_sea
30     - rearrange implicit part of u-equation in LSR solver to make it easier to
31       read, understand, and debug. This causes changes at the truncation level.
32     - fix (serious) bug in the boundary conditions (sign error in the implicit
33       part) of the LSR solver. Changes all LSR results.
34     - fixed problem with HSNOW initialization to avoid thick snow when AREA
35       is initilized with small values - does not change lab_sea results.
36     - added HsnowFile initialization capability
37    o pkg/smooth: addition to model/src and pkg/ctrl so allow
38     initialization of pkg/smooth and application to control vector
39    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
40    o dependencies: pkg/profiles requires pkg/cal
41    o pkg/profiles:
42     - added option ALLOW_PROFILES_GENERICGRID
43         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
44         that interpolation information (grid points and coefficients) is provided
45         within the netcdf input files.
46         -> sample matlab scripts can be found in MITgcm_contrib/gael
47         that allow you to prepare netcdf input files.
48     - also modified: cleaner include statements, cleaner error print statements,
49       cleaner stops when error, and more tests of the netcdf input files consistency.
50    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
51    o pkg/seaice:
52     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
53       requires a new routine: seaice_diagnostics_fill.F
54     - make sure that seaice does not move if not forced (pressure replacement
55       method, Hibler and Ip, 1995), changes results
56     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
57     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
58       It is turned off by default (=-1.), because it changes the results.
59     - make it possible to read AREA from a file, too.
60    
61    checkpoint59c
62    o add S/R and diagnostics for oceanic mixed-layer depth
63    o move GMRedi call after all vertical mixing schemes (including KPP)
64    o pkg/thsice:
65     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
66      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
67    o pkg/obcs:
68     - bug fix for balance code
69    o pkg/seaice:
70      - allow values of SEAICE_elasticParm > 1
71      - add new parameter SEAICE_evpTauRelax as an alternative
72        to SEAICE_elasticParm
73      - make lsr boundary conditions free slip (by default), changes result
74      - add code for no slip boundary conditions for lsr
75      - set minimum of zeta to zero (and not 4e8) (changes results)
76      - add a cap on AREA after advecting AREA if seaice_growth is not called
77    o change calculation of Visbeck K:
78      - no longer depend on tapering scheme; instead, compute slope (limited
79        by GM_maxSlope). this is equivalent to what was comuted before with
80        clipping or linear tappering.
81      - fix vertical averaging (wrong by 1/2 level)
82      - leave the old version (but will not be maintained) within
83        #ifdef OLD_VISBECK_CALC / #endif
84      - update output of exp. ideal_2D_oce
85    o change error catch in calc_r_star to improve vectorization
86  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
87    add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).    add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
88    o adjoint:
89      Re-organized adjoint checkpointing according to Matt Mazloff
90      (but with modifs/completions/cleanups)
91      Storing is now bundled into large arrays to optimized I/O
92      (and second step in cleanup of the_main_loop)
93    
94  checkpoint59b  checkpoint59b
95  o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):  o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
# Line 59  o pkg/exf: some cleaning-up: Line 143  o pkg/exf: some cleaning-up:
143  o pkg/thsice:  o pkg/thsice:
144   fix few little problems, in thsice_calc_thickn.F:   fix few little problems, in thsice_calc_thickn.F:
145    - growth vertically (and not laterally) if iceFrac == iceMaskMax    - growth vertically (and not laterally) if iceFrac == iceMaskMax
146    - melt laterally only if hIce < hThinIce (as the comments say)    - melt only laterally if hIce < hThinIce (as the comments say)
147    and in thsice_extend.F:    and in thsice_extend.F:
148    - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)    - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
149    - start to form ice as soon as the minimum ice-volume is reachable.    - start to form ice as soon as the minimum ice-volume is reachable.
