5      ==============================      ==============================
6    
7  o pkg/ctrl:  o pkg/diagnostics:
8     - deal with pairs of post-processed diags which are computed together; in
9       particular, re-order list of diags within 1 file to save 2nd computation.
10     - add S/R to compute velocity stream-function (called after velocity-potential
11       calculation) from divergence free transport -> new diagnostics "PsiVEL".
12     - add parameter to select grid-point location where PsiVEL == 0.
13    o eesupp/src:
14       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
15       (specific S/R needed with exch2 topology - for now, just print an error msg)
16    o pkg/shelfice
17     - Implement friction velocity-dependent transfer coefficients following
18       Holland and Jenkins, JPO, 1999
19       Original code by M. Losch with small modifs.
20       Enable with CPP option SHI_ALLOW_GAMMAFRICT
21       and runtime flag SHELFICEuseGammaFrict
22    o verification lab_sea & global_ocean.cs32x15:
23     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
24       does not miss some dependencies (but is slower) and also works with many files
25       (default makedepend limitation for AD built).
26     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
27    o pkg/diagnostics:
28     - add run-time parameter "useMissingValue" (def=False) to fill land-point
29        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
30       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
31     - Extend the use of "missing_value" setting from data.diagnostics for the case
32       of counter-diagnostics (where fraction-weight is zero). This applies both to
33       MNC and MDS output files.
34    o pkg/seaice/seaice_growth.F:
35      - add 'a priori' cap of latent heat flux based on actual mass considerations
36        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
37        non-legacy seaice_solve4temp.
38      - add diagnostic of the residual sublimation freshwater flux (the freshwater
39        flux taken from the ocean if the total actual latent heat fluxes exceed
40        the maximum)
41      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
42       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
43      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
44       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
45      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
46      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
47    o verification 1D_ocean_ice_column:
48       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
49       update results
50    o pkg/diagnostics:
51     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
52       which are not filled-up but computed from other diags ; In this case, the mate
53       diag points to the primary (filled-up) diag to used for post processing.
54     - Update Velocity-potential computation using post-processed diag framework.
55     ==> Change the ordering of fields and time-periods in MDS output file
56       when using periodic averaging: now writes one time record with the full set
57       of fields for this time period, then the next time reccord (it used to be
58       one field with the full set of time records then the next field).
59         Note: this is now similar to NetCDF (MNC) output file. <==
60    
61    checkpoint62z (2011/06/21)
62    o adjoint monitor:
63     - Add adjoint monitor output for packages exf, seaice
64       and update relevant testreport output
65    o pkg/seaice:
66     - re-order diags inits so that they appear in order in available_diagnostics.log
67     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
68       area/heff/hsnow preceeding thermodynamic growth/melt.
69     - modified diag: SIdA; output actual effect, as the description states.
70     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
71     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
72       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
73        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
74     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
75     - added diagnostics for seaice generic tracers (SItr*).
76     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
77     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
78     I. Fenty: 18-Jun-2011:
79     Minor changes to seaice package:
80     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
81        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
82       - Differentiated "regularization variables" from "floor variables"
83        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
84        * hiceMin became SEAICE_hice_reg (old hiceMin)
85          (with _reg meaning regularization variable)
86       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
87        so as to ensure energy conservation when going between phases
88      - A22 was not used anywhere
89     2) Changed regularization procedure for heffActual and hsnowActual to ensure
90        well-boundedness and smooth adjoint in seaice_growth.F
91     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
92        because the old regularization always set heffActual >= 0.05 cm
93     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
94        on AREA when HEFF > 0.
95      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
96        requiring that DISABLE_AREA_FLOOR *not* be defined
97     Affected verifications:
98      - 1D_ocean_ice_column (output.txt output_adm.txt)
99      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
100    o pkg/diagnostics:
101      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
102      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
103        (was _RL, now integer) with option = 0 to retrieve all levels.
104      - add pieces of code to compute velocity potential at each level (new diagnostics
105        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
106        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
107      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
108        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
109        and in diagnostics_fract_fill.F (do not need a valid pointer for the
110        diagnostics counter-mate); check that definition of counter-diagnostic
111        includes a valid counter-mate (in diagnostics_set_levels.F).
112    o model/src (rStar):
113      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
114        affect solution only if z* with full pressure in EOS;
115        update output of test-exp global_ocean.90x40x15.
116    o pkg/seaice:
117      - introduce siEps=1e-5 parameter
118      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
119      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
120      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
121        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
122        as well as ice cover age and ridging index (attached to AREA).
123        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
124        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
125        Up to SItrMaxNum=3 tracers can be used simultaneously.
126    o pkg/salt_plume:
127      -introduce SPsalFRAC run time parameter that sets the fraction of the
128       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
129       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
130    o model debug options:
131      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
132        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
133      - Refine debug-msg printing selection (3 new levels):
134        debugMode  : controls printing of debug messages (sequence of S/R calls).
135        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
136         debLevZero =  0 ; /* level of disabled aux. msg printing */
137         debLevA =  1 ; /* level of minimum  aux. msg printing */
138         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
139         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
140         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
141         debLevE =  5 ; /* level of extensive debug printing */
142        New debugLevel default: with default debugMode value (=F),
143          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
144          and if debugMode=T, default debugLevel = 4 (debLevD).
145        Relation with previous settings:
146         debLevB (=2) corresponds to former debLevA (=1)
147         debLevD (=4) corresponds to former debLevB (=2)
148        Note:
149         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
150         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
151            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
152      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
153        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
154    o pkg/obcs:
155      - change OBCSfixTopo default from True to False (should not change the results);
156        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
157    o pkg/thsice:
158      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
159        2nd layer seaice sublimation (unlikely to happen)
160      - use Interior mask for OBCS in thsice_advection.F (similar to what is
161        done in gad_advection & seaice_advection).
162    o adjoint:
163      bug fix spotted by Gael Forget:
164      seaice_advection and thsice_advection still had
165      legacy CPP options to avoid CS corner updates for adjoint
166    o pkg/seaice:
167      => Change some of the defaults (2011/05/29):
168         - change SEAICEuseFluxForm default (from False to True)
169         - change DIFF1 default (from 0.004 m/s to 0. m/s)
170         And print warnings if DIFF1 is not set in data.seaice and centered
171          avection scheme is used without any diffusion.
172      also:
173      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
174      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
175      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
176        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
177        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
178      update results of test exp.:
179         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
180             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
181             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
182         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
183         seaice_obcs: output (SEAICEuseFluxForm=T)
184      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
185          for standard fwd & AD lab_sea tests (to keep the same output).
186    o pkg/seaice/seaice_growth.F:
187      - use Ian Fenty's capping formulas for actual ice
188      thickness thoughout EVOLUTION branch.
189      - put treatment pathological case #2) in CPP brackets
190      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
191      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
192    o pkg/seaice:
193      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
194      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
195      also pass fac as a param, which can be 1. (to update the tendency
196      field) or the time step (to update the field itself).
197      - seaice_advdiff.F: for multidim, call seaice_diffusion with
198      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
199      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
200      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
201      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
202    o pkg/seaice:
203      diffusion with centered advection scheme (diffus.F & advect.F):
204      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
205        to just compute the laplacian of input-field.
206      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
207      - fix flux-form version in diffus.F to conserve tracer.
208      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
209       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
210    
211    checkpoint62y (2011/05/26)
212    o pkg/seaice:
213     - seaice_growth.F : in EVOLUTION branch, always include
214       a_QSWbyATM_cover in qnet (as it should be).
215     - verification/global_ocean.cs32x15 : update results accordingly
216       (output.seaice.txt output_adm.seaice.txt).
217    o pkg/seaice + obcs:
218     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
219       equivalent of assuming no tracer gradient outside the OB region.
220       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
221     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
222       after changes above);
223     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
224       only at OB location (instead of over a band of OLx width).
225    o pkg/seaice:
226     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
227       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
228    o pkg/obcs:
229      - split header file "OBCS.h" into 4 separated files:
230        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
231       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
232         (contain no conditional statement which depends on OBCS options).
233      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
234        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
235    o ctrl, cost, grdchk & autodiff pkgs:
236      - make options file more standard (like other {PKG}_OPTIONS.h file but
237        with AD_CONFIG.h); clean-up some of the included header files.
238    o pkg/obcs:
239      - do not mask tracer when applying OB (tracer == 0 could generate problems)
240      - apply tracer OB values to tracer field only at OB location (instead of
241        over a band of OLx width)
242      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
243      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
244        obcs_apply_tloc.F & obcs_apply_sloc.F
245    o obcs in model/src:
246      - call OBCS_APPLY_W only if NonHydrostatic.
247      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
248      - reset dEtaHdt and wVel to zero outside OB interior region ;
249      - leave tracer unchanged outside OB interior region: This has no effect
250        on the solution but just to prevent unrealistic tracer value outside OB.
251      - zero out velocity outside OB interior region: This has no effect on
252        the solution but just to prevent unrealistic velocity outside OB.
253    o obcs and non-lin free-surf:
254       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
255       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
256       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
257       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
258       update results of test-exp. exp4(nlfs).
259    o exp4 (nlfs) test-exp:
260       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
261       with NonLin-FreeSurf); update output.nlfs.txt
262    o obcs and 2d/3d solver norm:
263       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
264       and outside OB interior region (will allow to place OB further inside the
265       domain). Depending on the domain, can affects cg2d-Norm (previous
266       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
267       and cg3d-Norm (previous Norm was computed before canceling OB terms),
268       e.g. in tutorial_plume_on_slope.
269      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
270    o pkg rbcs:
271      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
272      - add capability to apply relaxation to horizontal velocity uVel & vVel.
273    o pkg/grdchk: add gradient check for control variable xx_shifwflx
274    o pkg/shelfice/shelfice_init_fixed.F
275      fix CPP-flag combinations
276    o pkg/seaice: Merge iceage code of Pierre Rampal
277      * update/change/correct ice age calculations
278      * add age updates for pathological cases
279      Probably needs more testing...
280    
281    checkpoint62x (2011/05/13)
282    o pkg/mom_vecinv:
283       high-order vorticity scheme: use interior masks (maskInW & S)
284       to zero-out (outside OB) gradient of vorticity.
285    o verification exp.:
286       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
287       hs94.128x64x5 and seaice_obcs ; update results.
288    o pkg/obcs:
289      fix bug in OBeta for YZ sections in obcs_exf_load.F
290    o pkg/ctrl, pkg/shelfice, and optim:
291      - add new control variable xx_shifwflx (fresh water flux underneath ice
292        shelves). This is almost as tedious as obcs-ctrl, because the
293        variables needs its own mask.
294      - add a cost function term that penalizes the deviation of xx_shifwflx
295        from the first guess (zero) in analogy to other control variables
296    o pkg/shelfice:
297      - start basic adjoint
298    o pkg/ctrl:
299      - remove extra 2D field "for good measure" when initializing in
300        ctrl_set_globfld_[xy/xz/yz].F
301    - 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
302    - improve error messages in ctrl_set_unpack_*    - improve error messages in ctrl_set_unpack_*
303  o OBC implementation in momentum:  o OBC implementation in momentum:
