5      ==============================      ==============================
6    
7    o adjoint monitor:
8     - Add adjoint monitor output for packages exf, seaice
9       and update relevant testreport output
10  o pkg/seaice:  o pkg/seaice:
11   - seaice_growth.F : in EVOLUTION branch, always include   - re-order diags inits so that they appear in order in available_diagnostics.log
12     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
13       area/heff/hsnow preceeding thermodynamic growth/melt.
14     - modified diag: SIdA; output actual effect, as the description states.
15     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
16     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
17       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
18        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
19     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
20     - added diagnostics for seaice genereic tracers (SItr*).
21     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
22     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
23    o pkg/diagnostics:
24      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
25      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
26        (was _RL, now integer) with option = 0 to retrieve all levels.
27      - add pieces of code to compute velocity potential at each level (new diagnostics
28        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
29        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
30    o model/src (rStar):
31      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
32        affect solution only if z* with full pressure in EOS;
33        update output of test-exp global_ocean.90x40x15.
34    o pkg/seaice:
35      - introduce siEps=1e-5 parameter
36      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
37      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
38      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
39        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
40        as well as ice cover age and ridging index (attached to AREA).
41        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
42        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
43        Up to SItrMaxNum=3 tracers can be used simultaneously.
44    o pkg/salt_plume:
45      -introduce SPsalFRAC run time parameter that sets the fraction of the
46       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
47       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
48    o model debug options:
49      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
50        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
51      - Refine debug-msg printing selection (3 new levels):
52        debugMode  : controls printing of debug messages (sequence of S/R calls).
53        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
54         debLevZero =  0 ; /* level of disabled aux. msg printing */
55         debLevA =  1 ; /* level of minimum  aux. msg printing */
56         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
57         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
58         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
59         debLevE =  5 ; /* level of extensive debug printing */
60        New debugLevel default: with default debugMode value (=F),
61          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
62          and if debugMode=T, default debugLevel = 4 (debLevD).
63        Relation with previous settings:
64         debLevB (=2) corresponds to former debLevA (=1)
65         debLevD (=4) corresponds to former debLevB (=2)
66        Note:
67         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
68         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
69            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
70      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
71        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
72    o pkg/obcs:
73      - change OBCSfixTopo default from True to False (should not change the results);
74        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
75    o pkg/thsice:
76      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
77        2nd layer seaice sublimation (unlikely to happen)
78      - use Interior mask for OBCS in thsice_advection.F (similar to what is
79        done in gad_advection & seaice_advection).
80    o adjoint:
81      bug fix spotted by Gael Forget:
82      seaice_advection and thsice_advection still had
83      legacy CPP options to avoid CS corner updates for adjoint
84    o pkg/seaice:
85      => Change some of the defaults (2011/05/29):
86         - change SEAICEuseFluxForm default (from False to True)
87         - change DIFF1 default (from 0.004 m/s to 0. m/s)
88         And print warnings if DIFF1 is not set in data.seaice and centered
89          avection scheme is used without any diffusion.
90      also:
91      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
92      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
93      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
94        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
95        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
96      update results of test exp.:
97         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
98             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
99             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
100         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
101         seaice_obcs: output (SEAICEuseFluxForm=T)
102      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
103          for standard fwd & AD lab_sea tests (to keep the same output).
104    o pkg/seaice/seaice_growth.F:
105      - use Ian Fenty's capping formulas for actual ice
106      thickness thoughout EVOLUTION branch.
107      - put treatment pathological case #2) in CPP brackets
108      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
109      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
110    o pkg/seaice:
111      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
112      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
113      also pass fac as a param, which can be 1. (to update the tendency
114      field) or the time step (to update the field itself).
115      - seaice_advdiff.F: for multidim, call seaice_diffusion with
116      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
117      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
118      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
119      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
120    o pkg/seaice:
121      diffusion with centered advection scheme (diffus.F & advect.F):
122      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
123        to just compute the laplacian of input-field.
124      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
125      - fix flux-form version in diffus.F to conserve tracer.
126      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
127       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
128    
129    checkpoint62y (2011/05/26)
130    o pkg/seaice:
131     - seaice_growth.F : in EVOLUTION branch, always include
132     a_QSWbyATM_cover in qnet (as it should be).     a_QSWbyATM_cover in qnet (as it should be).
133   - verification/global_ocean.cs32x15 : update results accordingly   - verification/global_ocean.cs32x15 : update results accordingly
134     (output.seaice.txt output_adm.seaice.txt).     (output.seaice.txt output_adm.seaice.txt).
135  o pkg/seaice + obcs:  o pkg/seaice + obcs:
136   - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:   - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
137     equivalent of assuming no tracer gradient outside the OB region.     equivalent of assuming no tracer gradient outside the OB region.
