4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src:
8      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
9        update output of test experiment bottom_ctrl_5x5.
10    o pkg/generic_advdiff:
11      - implement vertical bi-harmonic diffusion (for now, only for T & S and
12        only explicitly).
13    o verification/bottom_ctrl_5x5/
14      update reference output (results changed quite some time ago,
15      not sure when; but new reference results look ok in terms of grdchk)
16    o verification/1D_ocean_ice_column/
17      For verification purposes, the exact adjoint rather than an approx.
18      should be used (e.g., to comare against F.D. or TLM).
19      removed autodiff_inadmode*_ad.F routines in code_ad/
20      Update results/ accordingly.
21    o pkg/cal:
22      - change cal_getdate.F so that output date is function of input time only
23        (less ambiguous, not mixed up with input iteration number).
24      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
25    o pkg/diagnostics:
26      - implement calendarDumps also for stats-diags
27      - implement calendarDumps also for snap-shot output (negative freq)
28      - for now, ignores calendarDumps if non-zero phase-lag.
29    
30    checkpoint63n (2012/06/04)
31    o model/src:
32      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
33        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
34      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
35        similar to calc_r_star.F); update results of experiment internal_wave and
36        tutorial_global_oce_in_p (affected @ truncation level).
37    o pkg/shelfice:
38      - add parameterisation of advective-diffusive flux into the ice shelf
39        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
40      - simply eps3/3a computation
41    o eesupp:
42     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
43       between tiles, just fill-in edges assuming locally periodic subdomain) and
44       add corresponding exchange subroutines (EXCH0);
45     - new CG-solver version (_EX0) for disconnected-tiles special case.
46    o model/src (CG-solvers):
47     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
48       (similar final residual output and max-Iter number as with standard version);
49     - allows to store and use lowest-residual solution (standard & _SR versions);
50     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
51     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
52    o eesup/src:
53     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
54       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
55    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
56    
57    checkpoint63m (2012/04/27)
58    o pkg/shelfice:
59     - account for partical cells in surface level below ice-shelf for hydrostatic
60       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
61    o ad test experiments:
62     - update and rename to "ad_optfile.local" local AD-optfile specific to a
63       particular adjoint verification experiment (in verification/*/code_ad/)
64    o pkg/seaice & pkg/exf:
65     - Part two of ECCO-CLIVAR code merges.
66       Completes merge of seaice area relax. code.
67       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
68       to be set in EXF_OPTIONS.h since this pkg controls its I/O
69       (and avoids second CPP option in SEAICE_OPTIONS.h)
70     - change default value of costIceStart & costIceEnd to a valid date.
71     - add snowPrecip to HSNOW in seaice_growth
72    o pkg/ptracers:
73     - move ptracers summary and setup check into separated S/R ; add a check for
74       valid PTRACERS_Iter0 value (error+stop or just warning).
75    o pkg/cal (+ pkg/ecco):
76     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
77       as input; and for AD, unless both are not differentiable (e.g., k index)).
78    o model/src:
79     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
80       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
81       temporary set to usingZCoords value (to be changed to F when using shelfice).
82     - hydrostatic pressure: implement partial cell near the surface also for
83       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
84       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
85    o pkg/ctrl/ctrl_init.F:
86     - add a formal parameter to s/r ctrl_init_rec to print
87       xx_$(ctrl_valiable)_file for easier debugging
88     - move call of cal_* routines into the if-block where they are really
89       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
90       to specify a startdate
91    o pkg/seaice:
92     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
93       global_ocean.cs32x15/code versions).
94     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
95       verification experiment global_ocean.cs32x15.seaice and update results.
96    o pkg/exf:
97     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
98       (according to useExfYearlyFields).
99  o pkg/cal:  o pkg/cal:
100   - move calendar setting & summary (previously in cal_readparams.F) into new   - move calendar setting & summary (previously in cal_readparams.F) into new

106     - add a stop in all basic pkg/cal subroutines if called before setting is done.
107     - modify cal_getdate.F: stop when nothing was returned;
108       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
109       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
