6    
7  o pkg/ctrl:  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    
13    checkpoint62z (2011/06/21)
14    o adjoint monitor:
15     - Add adjoint monitor output for packages exf, seaice
16       and update relevant testreport output
17    o pkg/seaice:
18     - re-order diags inits so that they appear in order in available_diagnostics.log
19     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
20       area/heff/hsnow preceeding thermodynamic growth/melt.
21     - modified diag: SIdA; output actual effect, as the description states.
22     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
23     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
24       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
25        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
26     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
27     - added diagnostics for seaice generic tracers (SItr*).
28     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
29     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
30     I. Fenty: 18-Jun-2011:
31     Minor changes to seaice package:
32     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
33        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
34       - Differentiated "regularization variables" from "floor variables"
35        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
36        * hiceMin became SEAICE_hice_reg (old hiceMin)
37          (with _reg meaning regularization variable)
38       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
39        so as to ensure energy conservation when going between phases
40      - A22 was not used anywhere
41     2) Changed regularization procedure for heffActual and hsnowActual to ensure
42        well-boundedness and smooth adjoint in seaice_growth.F
43     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
44        because the old regularization always set heffActual >= 0.05 cm
45     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
46        on AREA when HEFF > 0.
47      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
48        requiring that DISABLE_AREA_FLOOR *not* be defined
49     Affected verifications:
50      - 1D_ocean_ice_column (output.txt output_adm.txt)
51      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
52    o pkg/diagnostics:
53      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
54      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
55        (was _RL, now integer) with option = 0 to retrieve all levels.
56      - add pieces of code to compute velocity potential at each level (new diagnostics
57        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
58        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
59      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
60        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
61        and in diagnostics_fract_fill.F (do not need a valid pointer for the
62        diagnostics counter-mate); check that definition of counter-diagnostic
63        includes a valid counter-mate (in diagnostics_set_levels.F).
64    o model/src (rStar):
65      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
66        affect solution only if z* with full pressure in EOS;
67        update output of test-exp global_ocean.90x40x15.
68    o pkg/seaice:
69      - introduce siEps=1e-5 parameter
70      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
71      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
72      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
73        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
74        as well as ice cover age and ridging index (attached to AREA).
75        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
76        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
77        Up to SItrMaxNum=3 tracers can be used simultaneously.
78    o pkg/salt_plume:
79      -introduce SPsalFRAC run time parameter that sets the fraction of the
80       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
81       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
82    o model debug options:
83      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
84        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
85      - Refine debug-msg printing selection (3 new levels):
86        debugMode  : controls printing of debug messages (sequence of S/R calls).
87        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
88         debLevZero =  0 ; /* level of disabled aux. msg printing */
89         debLevA =  1 ; /* level of minimum  aux. msg printing */
90         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
91         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
92         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
93         debLevE =  5 ; /* level of extensive debug printing */
94        New debugLevel default: with default debugMode value (=F),
95          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
96          and if debugMode=T, default debugLevel = 4 (debLevD).
97        Relation with previous settings:
98         debLevB (=2) corresponds to former debLevA (=1)
99         debLevD (=4) corresponds to former debLevB (=2)
100        Note:
101         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
102         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
103            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
104      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
105        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
106    o pkg/obcs:
107      - change OBCSfixTopo default from True to False (should not change the results);
108        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
109    o pkg/thsice:
110      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
111        2nd layer seaice sublimation (unlikely to happen)
112      - use Interior mask for OBCS in thsice_advection.F (similar to what is
113        done in gad_advection & seaice_advection).
114    o adjoint:
115      bug fix spotted by Gael Forget:
116      seaice_advection and thsice_advection still had
117      legacy CPP options to avoid CS corner updates for adjoint
118    o pkg/seaice:
119      => Change some of the defaults (2011/05/29):
120         - change SEAICEuseFluxForm default (from False to True)
121         - change DIFF1 default (from 0.004 m/s to 0. m/s)
122         And print warnings if DIFF1 is not set in data.seaice and centered
123          avection scheme is used without any diffusion.
124      also:
125      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
126      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
127      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
128        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
129        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
130      update results of test exp.:
131         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
132             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
133             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
134         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
135         seaice_obcs: output (SEAICEuseFluxForm=T)
136      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
137          for standard fwd & AD lab_sea tests (to keep the same output).
138    o pkg/seaice/seaice_growth.F:
139      - use Ian Fenty's capping formulas for actual ice
140      thickness thoughout EVOLUTION branch.
141      - put treatment pathological case #2) in CPP brackets
142      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
143      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
144    o pkg/seaice:
145      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
146      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
147      also pass fac as a param, which can be 1. (to update the tendency
148      field) or the time step (to update the field itself).
149      - seaice_advdiff.F: for multidim, call seaice_diffusion with
150      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
151      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
152      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
153      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
154    o pkg/seaice:
155      diffusion with centered advection scheme (diffus.F & advect.F):
156      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
157        to just compute the laplacian of input-field.
158      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
159      - fix flux-form version in diffus.F to conserve tracer.
160      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
161       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
162    
163    checkpoint62y (2011/05/26)
164    o pkg/seaice:
165     - seaice_growth.F : in EVOLUTION branch, always include
166       a_QSWbyATM_cover in qnet (as it should be).
167     - verification/global_ocean.cs32x15 : update results accordingly
168       (output.seaice.txt output_adm.seaice.txt).
169    o pkg/seaice + obcs:
170     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
171       equivalent of assuming no tracer gradient outside the OB region.
172       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
173     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
174       after changes above);
175     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
176       only at OB location (instead of over a band of OLx width).
177    o pkg/seaice:
178     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
179       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
180    o pkg/obcs:
181      - split header file "OBCS.h" into 4 separated files:
182        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
183       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
184         (contain no conditional statement which depends on OBCS options).
185      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
186        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
187    o ctrl, cost, grdchk & autodiff pkgs:
188      - make options file more standard (like other {PKG}_OPTIONS.h file but
189        with AD_CONFIG.h); clean-up some of the included header files.
190    o pkg/obcs:
191      - do not mask tracer when applying OB (tracer == 0 could generate problems)
192      - apply tracer OB values to tracer field only at OB location (instead of
193        over a band of OLx width)
194      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
195      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
196        obcs_apply_tloc.F & obcs_apply_sloc.F
197    o obcs in model/src:
198      - call OBCS_APPLY_W only if NonHydrostatic.
199      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
200      - reset dEtaHdt and wVel to zero outside OB interior region ;
201      - leave tracer unchanged outside OB interior region: This has no effect
202        on the solution but just to prevent unrealistic tracer value outside OB.
203      - zero out velocity outside OB interior region: This has no effect on
204        the solution but just to prevent unrealistic velocity outside OB.
205    o obcs and non-lin free-surf:
206       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
207       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
208       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
209       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
210       update results of test-exp. exp4(nlfs).
211    o exp4 (nlfs) test-exp:
212       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
213       with NonLin-FreeSurf); update output.nlfs.txt
214    o obcs and 2d/3d solver norm:
215       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
216       and outside OB interior region (will allow to place OB further inside the
217       domain). Depending on the domain, can affects cg2d-Norm (previous
218       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
219       and cg3d-Norm (previous Norm was computed before canceling OB terms),
220       e.g. in tutorial_plume_on_slope.
221      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
222    o pkg rbcs:
223      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
224      - add capability to apply relaxation to horizontal velocity uVel & vVel.
225    o pkg/grdchk: add gradient check for control variable xx_shifwflx
226    o pkg/shelfice/shelfice_init_fixed.F
227      fix CPP-flag combinations
228    o pkg/seaice: Merge iceage code of Pierre Rampal
229      * update/change/correct ice age calculations
230      * add age updates for pathological cases
231      Probably needs more testing...
232    
233    checkpoint62x (2011/05/13)
234    o pkg/mom_vecinv:
235       high-order vorticity scheme: use interior masks (maskInW & S)
236       to zero-out (outside OB) gradient of vorticity.
237    o verification exp.:
238       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
239       hs94.128x64x5 and seaice_obcs ; update results.
240    o pkg/obcs:
241      fix bug in OBeta for YZ sections in obcs_exf_load.F
242    o pkg/ctrl, pkg/shelfice, and optim:
243      - add new control variable xx_shifwflx (fresh water flux underneath ice
244        shelves). This is almost as tedious as obcs-ctrl, because the
245        variables needs its own mask.
246      - add a cost function term that penalizes the deviation of xx_shifwflx
247        from the first guess (zero) in analogy to other control variables
248    o pkg/shelfice:
249      - start basic adjoint
250    o pkg/ctrl:
251    - remove extra 2D field "for good measure" when initializing in    - remove extra 2D field "for good measure" when initializing in
252      ctrl_set_globfld_[xy/xz/yz].F      ctrl_set_globfld_[xy/xz/yz].F
253    - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec    - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
