5      ==============================      ==============================
6    
7  o pkg/seaice:  o pkg/exch2:
8     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
9     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
10       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
11       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
12    o pkg/diagnostics:
13     - deal with pairs of post-processed diags which are computed together; in
14       particular, re-order list of diags within 1 file to save 2nd computation.
15     - add S/R to compute velocity stream-function (called after velocity-potential
16       calculation) from divergence free transport -> new diagnostics "PsiVEL".
17     - add parameter to select grid-point location where PsiVEL == 0.
18    o eesupp/src:
19       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
20       (specific S/R needed with exch2 topology - for now, just print an error msg)
21    o pkg/shelfice
22     - Implement friction velocity-dependent transfer coefficients following
23       Holland and Jenkins, JPO, 1999
24       Original code by M. Losch with small modifs.
25       Enable with CPP option SHI_ALLOW_GAMMAFRICT
26       and runtime flag SHELFICEuseGammaFrict
27    o verification lab_sea & global_ocean.cs32x15:
28     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
29       does not miss some dependencies (but is slower) and also works with many files
30       (default makedepend limitation for AD built).
31     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
32    o pkg/diagnostics:
33     - add run-time parameter "useMissingValue" (def=False) to fill land-point
34        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
35       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
36     - Extend the use of "missing_value" setting from data.diagnostics for the case
37       of counter-diagnostics (where fraction-weight is zero). This applies both to
38       MNC and MDS output files.
39    o pkg/seaice/seaice_growth.F:
40      - add 'a priori' cap of latent heat flux based on actual mass considerations
41        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
42        non-legacy seaice_solve4temp.
43      - add diagnostic of the residual sublimation freshwater flux (the freshwater
44        flux taken from the ocean if the total actual latent heat fluxes exceed
45        the maximum)
46      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
47       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
48      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
49       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
50      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
51      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
52    o verification 1D_ocean_ice_column:
53       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
54       update results
55    o pkg/diagnostics:
56     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
57       which are not filled-up but computed from other diags ; In this case, the mate
58       diag points to the primary (filled-up) diag to used for post processing.
59     - Update Velocity-potential computation using post-processed diag framework.
60     ==> Change the ordering of fields and time-periods in MDS output file
61       when using periodic averaging: now writes one time record with the full set
62       of fields for this time period, then the next time reccord (it used to be
63       one field with the full set of time records then the next field).
64         Note: this is now similar to NetCDF (MNC) output file. <==
65    
66    checkpoint62z (2011/06/21)
67    o adjoint monitor:
68     - Add adjoint monitor output for packages exf, seaice
69       and update relevant testreport output
70    o pkg/seaice:
71     - re-order diags inits so that they appear in order in available_diagnostics.log
72     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
73       area/heff/hsnow preceeding thermodynamic growth/melt.
74     - modified diag: SIdA; output actual effect, as the description states.
75     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
76     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
77       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
78        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
79     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
80     - added diagnostics for seaice generic tracers (SItr*).
81     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
82     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
83     I. Fenty: 18-Jun-2011:
84     Minor changes to seaice package:
85     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
86        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
87       - Differentiated "regularization variables" from "floor variables"
88        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
89        * hiceMin became SEAICE_hice_reg (old hiceMin)
90          (with _reg meaning regularization variable)
91       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
92        so as to ensure energy conservation when going between phases
93      - A22 was not used anywhere
94     2) Changed regularization procedure for heffActual and hsnowActual to ensure
95        well-boundedness and smooth adjoint in seaice_growth.F
96     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
97        because the old regularization always set heffActual >= 0.05 cm
98     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
99        on AREA when HEFF > 0.
100      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
101        requiring that DISABLE_AREA_FLOOR *not* be defined
102     Affected verifications:
103      - 1D_ocean_ice_column (output.txt output_adm.txt)
104      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
105    o pkg/diagnostics:
106      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
107      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
108        (was _RL, now integer) with option = 0 to retrieve all levels.
109      - add pieces of code to compute velocity potential at each level (new diagnostics
110        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
111        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
112      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
113        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
114        and in diagnostics_fract_fill.F (do not need a valid pointer for the
115        diagnostics counter-mate); check that definition of counter-diagnostic
116        includes a valid counter-mate (in diagnostics_set_levels.F).
117    o model/src (rStar):
118      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
119        affect solution only if z* with full pressure in EOS;
120        update output of test-exp global_ocean.90x40x15.
121    o pkg/seaice:
