7  o pkg/seaice:  o pkg/diagnostics:
8     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
9       which are not filled-up but computed from other diags ; In this case, the mate
10       diag points to the primary (filled-up) diag to used for post processing.
11     - Update Velocity-potential computation using post-processed diag framework.
12     Change the ordering of fields and time-periods in MDS output file
13       when using periodic averaging: now writes one time record with the full set
14       of fields for this time period, then the next time reccord (it used to be
15       one field with the full set of time records then the next field).
16       Note: this is now similar to NetCDF (MNC) output file.

19    o adjoint monitor:
20     - Add adjoint monitor output for packages exf, seaice
21       and update relevant testreport output
22    o pkg/seaice:
23     - re-order diags inits so that they appear in order in available_diagnostics.log
24     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
25       area/heff/hsnow preceeding thermodynamic growth/melt.
26     - modified diag: SIdA; output actual effect, as the description states.
27     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
28     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
29       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
30        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
31     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
32     - added diagnostics for seaice generic tracers (SItr*).
33     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
34     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
35     I. Fenty: 18-Jun-2011:
36     Minor changes to seaice package:
37     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
38        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
39       - Differentiated "regularization variables" from "floor variables"
40        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
41        * hiceMin became SEAICE_hice_reg (old hiceMin)
42          (with _reg meaning regularization variable)
43       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
44        so as to ensure energy conservation when going between phases
45      - A22 was not used anywhere
46     2) Changed regularization procedure for heffActual and hsnowActual to ensure
47        well-boundedness and smooth adjoint in seaice_growth.F
48     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
49        because the old regularization always set heffActual >= 0.05 cm
50     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
51        on AREA when HEFF > 0.
52      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
53        requiring that DISABLE_AREA_FLOOR *not* be defined
54     Affected verifications:
55      - 1D_ocean_ice_column (output.txt output_adm.txt)
56      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
57    o pkg/diagnostics:
58      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
59      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
60        (was _RL, now integer) with option = 0 to retrieve all levels.
61      - add pieces of code to compute velocity potential at each level (new diagnostics
62        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
63        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
64      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
65        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
66        and in diagnostics_fract_fill.F (do not need a valid pointer for the
67        diagnostics counter-mate); check that definition of counter-diagnostic
68        includes a valid counter-mate (in diagnostics_set_levels.F).
69    o model/src (rStar):
70      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
71        affect solution only if z* with full pressure in EOS;
72        update output of test-exp global_ocean.90x40x15.
