4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/diagnostics:
8     - add run-time parameter "useMissingValue" (def=False) to fill land-point
9        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
10       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
11     - Extend the use of "missing_value" setting from data.diagnostics for the case
12       of counter-diagnostics (where fraction-weight is zero). This applies both to
13       MNC and MDS output files.
14    o pkg/seaice/seaice_growth.F:
15      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
16       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
17      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
18       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
19      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
20      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
21    o verification 1D_ocean_ice_column:
22       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
23       update results
24    o pkg/diagnostics:
25     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
26       which are not filled-up but computed from other diags ; In this case, the mate
27       diag points to the primary (filled-up) diag to used for post processing.
28     - Update Velocity-potential computation using post-processed diag framework.
29     ==> Change the ordering of fields and time-periods in MDS output file
30       when using periodic averaging: now writes one time record with the full set
31       of fields for this time period, then the next time reccord (it used to be
32       one field with the full set of time records then the next field).
33         Note: this is now similar to NetCDF (MNC) output file. <==
34    
35    checkpoint62z (2011/06/21)
36    o adjoint monitor:
37     - Add adjoint monitor output for packages exf, seaice
38       and update relevant testreport output
39    o pkg/seaice:
40     - re-order diags inits so that they appear in order in available_diagnostics.log
41     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
42       area/heff/hsnow preceeding thermodynamic growth/melt.
43     - modified diag: SIdA; output actual effect, as the description states.
44     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
45     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
46       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
47        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
48     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
49     - added diagnostics for seaice generic tracers (SItr*).
50     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
51     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
52     I. Fenty: 18-Jun-2011:
53     Minor changes to seaice package:
54     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
55        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
56       - Differentiated "regularization variables" from "floor variables"
57        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
58        * hiceMin became SEAICE_hice_reg (old hiceMin)
59          (with _reg meaning regularization variable)
60       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
61        so as to ensure energy conservation when going between phases
62      - A22 was not used anywhere
63     2) Changed regularization procedure for heffActual and hsnowActual to ensure
64        well-boundedness and smooth adjoint in seaice_growth.F
65     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
66        because the old regularization always set heffActual >= 0.05 cm
67     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
68        on AREA when HEFF > 0.
69      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
70        requiring that DISABLE_AREA_FLOOR *not* be defined
71     Affected verifications:
72      - 1D_ocean_ice_column (output.txt output_adm.txt)
73      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
74    o pkg/diagnostics:
75      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
76      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
77        (was _RL, now integer) with option = 0 to retrieve all levels.
78      - add pieces of code to compute velocity potential at each level (new diagnostics
79        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
80        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
81      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
82        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
83        and in diagnostics_fract_fill.F (do not need a valid pointer for the
84        diagnostics counter-mate); check that definition of counter-diagnostic
85        includes a valid counter-mate (in diagnostics_set_levels.F).
86    o model/src (rStar):
87      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
88        affect solution only if z* with full pressure in EOS;
89        update output of test-exp global_ocean.90x40x15.
90    o pkg/seaice:
91      - introduce siEps=1e-5 parameter
92      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
93      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
94      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
95        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
96        as well as ice cover age and ridging index (attached to AREA).
97        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
98        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
99        Up to SItrMaxNum=3 tracers can be used simultaneously.
100    o pkg/salt_plume:
101      -introduce SPsalFRAC run time parameter that sets the fraction of the
102       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
103       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
104    o model debug options:
105      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
106        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
107      - Refine debug-msg printing selection (3 new levels):
108        debugMode  : controls printing of debug messages (sequence of S/R calls).
109        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
110         debLevZero =  0 ; /* level of disabled aux. msg printing */
111         debLevA =  1 ; /* level of minimum  aux. msg printing */
112         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
113         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
114         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
115         debLevE =  5 ; /* level of extensive debug printing */
116        New debugLevel default: with default debugMode value (=F),
117          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
118          and if debugMode=T, default debugLevel = 4 (debLevD).
119        Relation with previous settings:
120         debLevB (=2) corresponds to former debLevA (=1)
121         debLevD (=4) corresponds to former debLevB (=2)
122        Note:
123         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
124         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
125            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
126      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
127        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
128    o pkg/obcs:
129      - change OBCSfixTopo default from True to False (should not change the results);
130        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
131    o pkg/thsice:
132      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
133        2nd layer seaice sublimation (unlikely to happen)
134      - use Interior mask for OBCS in thsice_advection.F (similar to what is
135        done in gad_advection & seaice_advection).
136    o adjoint:
137      bug fix spotted by Gael Forget:
138      seaice_advection and thsice_advection still had
139      legacy CPP options to avoid CS corner updates for adjoint
140    o pkg/seaice:
141      => Change some of the defaults (2011/05/29):
142         - change SEAICEuseFluxForm default (from False to True)
143         - change DIFF1 default (from 0.004 m/s to 0. m/s)
144         And print warnings if DIFF1 is not set in data.seaice and centered
145          avection scheme is used without any diffusion.
146      also:
147      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
148      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
149      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
150        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
151        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
152      update results of test exp.:
153         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
154             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
155             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
156         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
157         seaice_obcs: output (SEAICEuseFluxForm=T)
158      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
159          for standard fwd & AD lab_sea tests (to keep the same output).
160    o pkg/seaice/seaice_growth.F:
161      - use Ian Fenty's capping formulas for actual ice
162      thickness thoughout EVOLUTION branch.
163      - put treatment pathological case #2) in CPP brackets
164      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
165      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
166    o pkg/seaice:
167      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
168      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
169      also pass fac as a param, which can be 1. (to update the tendency
170      field) or the time step (to update the field itself).
171      - seaice_advdiff.F: for multidim, call seaice_diffusion with
172      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
173      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
174      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
175      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
176    o pkg/seaice:
177      diffusion with centered advection scheme (diffus.F & advect.F):
178      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
179        to just compute the laplacian of input-field.
180      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
181      - fix flux-form version in diffus.F to conserve tracer.
182      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
183       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
184    
185    checkpoint62y (2011/05/26)
186    o pkg/seaice:
187     - seaice_growth.F : in EVOLUTION branch, always include
188       a_QSWbyATM_cover in qnet (as it should be).
189     - verification/global_ocean.cs32x15 : update results accordingly
190       (output.seaice.txt output_adm.seaice.txt).
191    o pkg/seaice + obcs:
192     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
193       equivalent of assuming no tracer gradient outside the OB region.
194       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
195     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
196       after changes above);
197     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
198       only at OB location (instead of over a band of OLx width).
199    o pkg/seaice:
200     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
201       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
202    o pkg/obcs:
203      - split header file "OBCS.h" into 4 separated files:
204        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
205       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
206         (contain no conditional statement which depends on OBCS options).
207      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
208        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
209    o ctrl, cost, grdchk & autodiff pkgs:
210      - make options file more standard (like other {PKG}_OPTIONS.h file but
211        with AD_CONFIG.h); clean-up some of the included header files.
212    o pkg/obcs:
213      - do not mask tracer when applying OB (tracer == 0 could generate problems)
214      - apply tracer OB values to tracer field only at OB location (instead of
215        over a band of OLx width)
216      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
217      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
218        obcs_apply_tloc.F & obcs_apply_sloc.F
219    o obcs in model/src:
220      - call OBCS_APPLY_W only if NonHydrostatic.
221      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
222      - reset dEtaHdt and wVel to zero outside OB interior region ;
223      - leave tracer unchanged outside OB interior region: This has no effect
224        on the solution but just to prevent unrealistic tracer value outside OB.
225      - zero out velocity outside OB interior region: This has no effect on
226        the solution but just to prevent unrealistic velocity outside OB.
227    o obcs and non-lin free-surf:
228       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
229       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
230       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
231       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
232       update results of test-exp. exp4(nlfs).
233    o exp4 (nlfs) test-exp:
234       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
235       with NonLin-FreeSurf); update output.nlfs.txt
236    o obcs and 2d/3d solver norm:
237       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
238       and outside OB interior region (will allow to place OB further inside the
239       domain). Depending on the domain, can affects cg2d-Norm (previous
240       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
241       and cg3d-Norm (previous Norm was computed before canceling OB terms),
242       e.g. in tutorial_plume_on_slope.
243      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
244    o pkg rbcs:
245      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
246      - add capability to apply relaxation to horizontal velocity uVel & vVel.
247    o pkg/grdchk: add gradient check for control variable xx_shifwflx
248    o pkg/shelfice/shelfice_init_fixed.F
249      fix CPP-flag combinations
250    o pkg/seaice: Merge iceage code of Pierre Rampal
251      * update/change/correct ice age calculations
252      * add age updates for pathological cases
253      Probably needs more testing...
254    
255    checkpoint62x (2011/05/13)
256    o pkg/mom_vecinv:
257       high-order vorticity scheme: use interior masks (maskInW & S)
258       to zero-out (outside OB) gradient of vorticity.
259    o verification exp.:
260       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
261       hs94.128x64x5 and seaice_obcs ; update results.
262    o pkg/obcs:
263      fix bug in OBeta for YZ sections in obcs_exf_load.F
264    o pkg/ctrl, pkg/shelfice, and optim:
265      - add new control variable xx_shifwflx (fresh water flux underneath ice
266        shelves). This is almost as tedious as obcs-ctrl, because the
267        variables needs its own mask.
268      - add a cost function term that penalizes the deviation of xx_shifwflx
269        from the first guess (zero) in analogy to other control variables
270    o pkg/shelfice:
271      - start basic adjoint
272    o pkg/ctrl:
273      - remove extra 2D field "for good measure" when initializing in
274        ctrl_set_globfld_[xy/xz/yz].F
275      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
276      - improve error messages in ctrl_set_unpack_*
277    o OBC implementation in momentum:
278       use interior masks (maskInC,W & S) in momentum S/R:
279       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
280       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
281       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
282       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
283       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
284        (and also with Leith/Smagorinsky harmonic-viscosity).
285       Update output of experiment dome and exp4 (+nlfs).
286    o exp4 test-exp:
287      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
288        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
289        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
290        time-varying OB at Western-side for wVel (NonHyd); update output.
291      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
292        and biharmonic-viscosity ; also use prescribed time varying OB.
293    o pkg/obcs:
294      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
295    o model/src:
296      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
297      - initialise startTime & nIter0 with unlikely values: allows to set one
298        from the other without ambiguity.
299    o seaice_obcs test-exp.:
300      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
301    o pkg/obcs:
302      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
303        no longer needed with maskInC,W,S in pkg/generic_advdiff.
304    o pkg/seaice:
305      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
306        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
307      - fixed bug in the initialization of sea ice salinity variable HSALT
308        in seaice_init_varia.F  (removed dependence on ICE2WATR)
309    o fizhi-cs test exp.:
310       switch reference output convention for these 2 non-standard test-exp,
311        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
312          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
313       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
314    o model/inc:
315      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
316        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
317    o pkg/seaice:
318      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
319    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
320      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
321        and initial HSALT
322    
323    checkpoint62w (2011/04/26)
324    o pkg/mom_fluxform:
325      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
326      - use parameter "sideDragFactor" in no-slip BC side-drag part.
327      - update output of exp. global_ocean.90x40x15
328    o pkg/mom_vecinv:
329      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
330    o update seaice exp.:
331      use more consistent parameter values (remove "backward compatability only":
332       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
333      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
334       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
335    o update test-exp global_ocean.90x40x15:
336      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
337      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
338      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
339      o turn on zStar & viscA4 in standard set-up (dir input/)
340        and update output files: output.txt & output.dwnslp.txt
341    o new AD-test experiment: obcs_ctrl
342      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
343    o pkg/dic:
344      fix two bugs in handling water vapour pressure in carbonate chemistry
345      and air-sea fluxes. Found by Val Bennington and Galen McKinley
346      (add DIC Option = WATERVAP_BUG to recover old results)
347      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
348    o adding allowInteriorFreezing option to check for water below freezing point
349      at depth and bring the negative heat anomaly to the surface level
350    o pkgs _fields_load:
351      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
352      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
353        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
354        rbcs to get interpolation weights and time reccord number.
355      - fix multi-threading in aim_fields_load.F
356      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
357  o external_fields_load:  o external_fields_load:
358    new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear    new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
359     interpolation weights) to use in a periodic time-series ; do not divide by     interpolation weights) to use in a periodic time-series ; do not divide by
