4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice/seaice_growth.F
8      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
9        remove then obsolete STORE directives
10      - fix STORE directives for tice and tices, so that only the
11        appropriate part of the fields are stored (and not the entire
12        field)
13      - cosmetic changes: adjust CPP flags and indentation for better
14        legibilty
15    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
16      Chris Wilson)
17    o pkg/gmredi:
18       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
19       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
20    
21    checkpoint63 (2011/07/11)
22    o pkg/exch2:
23     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
24     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
25       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
26       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
27    o pkg/diagnostics:
28     - deal with pairs of post-processed diags which are computed together; in
29       particular, re-order list of diags within 1 file to save 2nd computation.
30     - add S/R to compute velocity stream-function (called after velocity-potential
31       calculation) from divergence free transport -> new diagnostics "PsiVEL".
32     - add parameter to select grid-point location where PsiVEL == 0.
33    o eesupp/src:
34       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
35       (specific S/R needed with exch2 topology - for now, just print an error msg)
36    o pkg/shelfice
37     - Implement friction velocity-dependent transfer coefficients following
38       Holland and Jenkins, JPO, 1999
39       Original code by M. Losch with small modifs.
40       Enable with CPP option SHI_ALLOW_GAMMAFRICT
41       and runtime flag SHELFICEuseGammaFrict
42    o verification lab_sea & global_ocean.cs32x15:
43     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
44       does not miss some dependencies (but is slower) and also works with many files
45       (default makedepend limitation for AD built).
46     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
47    o pkg/diagnostics:
48     - add run-time parameter "useMissingValue" (def=False) to fill land-point
49        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
50       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
51     - Extend the use of "missing_value" setting from data.diagnostics for the case
52       of counter-diagnostics (where fraction-weight is zero). This applies both to
53       MNC and MDS output files.
54    o pkg/seaice/seaice_growth.F:
55      - add 'a priori' cap of latent heat flux based on actual mass considerations
56        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
57        non-legacy seaice_solve4temp.
58      - add diagnostic of the residual sublimation freshwater flux (the freshwater
59        flux taken from the ocean if the total actual latent heat fluxes exceed
60        the maximum)
61      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
62       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
63      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
64       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
65      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
66      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
67    o verification 1D_ocean_ice_column:
68       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
69       update results
70    o pkg/diagnostics:
71     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
72       which are not filled-up but computed from other diags ; In this case, the mate
73       diag points to the primary (filled-up) diag to used for post processing.
74     - Update Velocity-potential computation using post-processed diag framework.
75     ==> Change the ordering of fields and time-periods in MDS output file
76       when using periodic averaging: now writes one time record with the full set
77       of fields for this time period, then the next time reccord (it used to be
78       one field with the full set of time records then the next field).
79         Note: this is now similar to NetCDF (MNC) output file. <==
80    
81    checkpoint62z (2011/06/21)
82    o adjoint monitor:
83     - Add adjoint monitor output for packages exf, seaice
84       and update relevant testreport output
85    o pkg/seaice:
86     - re-order diags inits so that they appear in order in available_diagnostics.log
87     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
88       area/heff/hsnow preceeding thermodynamic growth/melt.
89     - modified diag: SIdA; output actual effect, as the description states.
90     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
91     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
92       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
93        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
94     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
95     - added diagnostics for seaice generic tracers (SItr*).
96     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
97     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
98     I. Fenty: 18-Jun-2011:
99     Minor changes to seaice package:
100     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
101        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
102       - Differentiated "regularization variables" from "floor variables"
103        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
104        * hiceMin became SEAICE_hice_reg (old hiceMin)
105          (with _reg meaning regularization variable)
106       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
107        so as to ensure energy conservation when going between phases
108      - A22 was not used anywhere
109     2) Changed regularization procedure for heffActual and hsnowActual to ensure
110        well-boundedness and smooth adjoint in seaice_growth.F
111     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
112        because the old regularization always set heffActual >= 0.05 cm
113     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
114        on AREA when HEFF > 0.
115      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
116        requiring that DISABLE_AREA_FLOOR *not* be defined
117     Affected verifications:
118      - 1D_ocean_ice_column (output.txt output_adm.txt)
119      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
120  o pkg/diagnostics:  o pkg/diagnostics:
121    - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).    - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
122    - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument    - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
123      (was _RL, now integer) with option = 0 to retrieve all levels.      (was _RL, now integer) with option = 0 to retrieve all levels.
124      - add pieces of code to compute velocity potential at each level (new diagnostics
125        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
126        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
127      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
128        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
129        and in diagnostics_fract_fill.F (do not need a valid pointer for the
130        diagnostics counter-mate); check that definition of counter-diagnostic
131        includes a valid counter-mate (in diagnostics_set_levels.F).
132  o model/src (rStar):  o model/src (rStar):
133    - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);    - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
134      affect solution only if z* with full pressure in EOS;      affect solution only if z* with full pressure in EOS;
