4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o optim/optim_readdata.F:
8      - add some output about obcs variables that might help debugging
9      - add a check about nvarlength
10    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
11    o pkg/diagnostics (velocity potential):
12      - fix mask for OBCS (still problems in stream-function with OBCS);
13      - add specific parameter (default = main code CG2D params) for solver;
14      - in case of poor convergence, use solution corresponding to lowest residual.
15    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
16      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
17      and should be avoided where possible.
18    o model/src (rStar):
19      - include r* effect on reference-state (PhiRef) in totPhiHyd
20        (so that it's really the potential anomaly at the cell center);
21        affect solution only if z* with full pressure in EOS.
22      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
23        update output (because of z* in totPhiHyd and viscA4 changes);
24      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
25        @ constant r) until interpolation at constant r is implemented.
26    o pkg/diagnostics
27      - fix RCENTER diagnostics in case cell center is not at interface middle
28    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
29      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
30      that THETA and SALT are "conservative temperature" and "absolute
31      salinity"
32    o pkg/ctrl
33      - fix computation of endrec in s/r ctrl_init_rec
34      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
35    o pkg/seaice/seaice_growth.F
36      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
37        remove then obsolete STORE directives
38      - fix STORE directives for tice and tices, so that only the
39        appropriate part of the fields are stored (and not the entire
40        field); update global_ocean.cs32x15.seaice AD output.
41      - cosmetic changes: adjust CPP flags and indentation for better
42        legibilty
43    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
44      Chris Wilson)
45    o pkg/gmredi:
46       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
47       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
48    
49    checkpoint63 (2011/07/11)
50    o pkg/exch2:
51     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
52     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
53       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
54       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
55    o pkg/diagnostics:
56     - deal with pairs of post-processed diags which are computed together; in
57       particular, re-order list of diags within 1 file to save 2nd computation.
58     - add S/R to compute velocity stream-function (called after velocity-potential
59       calculation) from divergence free transport -> new diagnostics "PsiVEL".
60     - add parameter to select grid-point location where PsiVEL == 0.
61    o eesupp/src:
62       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
63       (specific S/R needed with exch2 topology - for now, just print an error msg)
64    o pkg/shelfice
65     - Implement friction velocity-dependent transfer coefficients following
66       Holland and Jenkins, JPO, 1999
67       Original code by M. Losch with small modifs.
68       Enable with CPP option SHI_ALLOW_GAMMAFRICT
69       and runtime flag SHELFICEuseGammaFrict
70    o verification lab_sea & global_ocean.cs32x15:
71     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
72       does not miss some dependencies (but is slower) and also works with many files
73       (default makedepend limitation for AD built).
74     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
75    o pkg/diagnostics:
76     - add run-time parameter "useMissingValue" (def=False) to fill land-point
77        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
78       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
79     - Extend the use of "missing_value" setting from data.diagnostics for the case
80       of counter-diagnostics (where fraction-weight is zero). This applies both to
81       MNC and MDS output files.
82    o pkg/seaice/seaice_growth.F:
83      - add 'a priori' cap of latent heat flux based on actual mass considerations
84        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
85        non-legacy seaice_solve4temp.
86      - add diagnostic of the residual sublimation freshwater flux (the freshwater
87        flux taken from the ocean if the total actual latent heat fluxes exceed
88        the maximum)
89      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
90       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
91      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
92       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
93      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
94      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
95    o verification 1D_ocean_ice_column:
96       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
97       update results
98    o pkg/diagnostics:
99     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
100       which are not filled-up but computed from other diags ; In this case, the mate
101       diag points to the primary (filled-up) diag to used for post processing.
102     - Update Velocity-potential computation using post-processed diag framework.
103     ==> Change the ordering of fields and time-periods in MDS output file
104       when using periodic averaging: now writes one time record with the full set
105       of fields for this time period, then the next time reccord (it used to be
106       one field with the full set of time records then the next field).
107         Note: this is now similar to NetCDF (MNC) output file. <==
108    
109    checkpoint62z (2011/06/21)
110    o adjoint monitor:
111     - Add adjoint monitor output for packages exf, seaice
112       and update relevant testreport output
113    o pkg/seaice:
114     - re-order diags inits so that they appear in order in available_diagnostics.log
115     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
116       area/heff/hsnow preceeding thermodynamic growth/melt.
117     - modified diag: SIdA; output actual effect, as the description states.
118     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
119     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
120       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
121        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
122     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
123     - added diagnostics for seaice generic tracers (SItr*).
124     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
125     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
126     I. Fenty: 18-Jun-2011:
127     Minor changes to seaice package:
128     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
129        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
130       - Differentiated "regularization variables" from "floor variables"
131        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
132        * hiceMin became SEAICE_hice_reg (old hiceMin)
133          (with _reg meaning regularization variable)
134       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
135        so as to ensure energy conservation when going between phases
136      - A22 was not used anywhere
137     2) Changed regularization procedure for heffActual and hsnowActual to ensure
138        well-boundedness and smooth adjoint in seaice_growth.F
139     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
140        because the old regularization always set heffActual >= 0.05 cm
141     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
142        on AREA when HEFF > 0.
143      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
144        requiring that DISABLE_AREA_FLOOR *not* be defined
145     Affected verifications:
146      - 1D_ocean_ice_column (output.txt output_adm.txt)
147      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
148    o pkg/diagnostics:
149      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
150      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
151        (was _RL, now integer) with option = 0 to retrieve all levels.
152      - add pieces of code to compute velocity potential at each level (new diagnostics
153        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
154        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
155      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
156        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
157        and in diagnostics_fract_fill.F (do not need a valid pointer for the
158        diagnostics counter-mate); check that definition of counter-diagnostic
159        includes a valid counter-mate (in diagnostics_set_levels.F).
160    o model/src (rStar):
161      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
162        affect solution only if z* with full pressure in EOS;
163        update output of test-exp global_ocean.90x40x15.
164    o pkg/seaice:
165      - introduce siEps=1e-5 parameter
166      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
167      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
168      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
169        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
170        as well as ice cover age and ridging index (attached to AREA).
171        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
172        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
173        Up to SItrMaxNum=3 tracers can be used simultaneously.
174    o pkg/salt_plume:
175      -introduce SPsalFRAC run time parameter that sets the fraction of the
176       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
177       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
178    o model debug options:
179      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
180        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
181      - Refine debug-msg printing selection (3 new levels):
182        debugMode  : controls printing of debug messages (sequence of S/R calls).
183        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
184         debLevZero =  0 ; /* level of disabled aux. msg printing */
185         debLevA =  1 ; /* level of minimum  aux. msg printing */
186         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
187         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
188         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
189         debLevE =  5 ; /* level of extensive debug printing */
190        New debugLevel default: with default debugMode value (=F),
191          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
192          and if debugMode=T, default debugLevel = 4 (debLevD).
193        Relation with previous settings:
194         debLevB (=2) corresponds to former debLevA (=1)
195         debLevD (=4) corresponds to former debLevB (=2)
196        Note:
197         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
198         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
199            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
200      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
201        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
202    o pkg/obcs:
203      - change OBCSfixTopo default from True to False (should not change the results);
204        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
205    o pkg/thsice:
206      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
207        2nd layer seaice sublimation (unlikely to happen)
208      - use Interior mask for OBCS in thsice_advection.F (similar to what is
209        done in gad_advection & seaice_advection).
210    o adjoint:
211      bug fix spotted by Gael Forget:
212      seaice_advection and thsice_advection still had
213      legacy CPP options to avoid CS corner updates for adjoint
214    o pkg/seaice:
215      => Change some of the defaults (2011/05/29):
216         - change SEAICEuseFluxForm default (from False to True)
217         - change DIFF1 default (from 0.004 m/s to 0. m/s)
218         And print warnings if DIFF1 is not set in data.seaice and centered
219          avection scheme is used without any diffusion.
220      also:
221      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
222      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
223      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
224        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
225        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
226      update results of test exp.:
227         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
228             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
229             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
230         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
231         seaice_obcs: output (SEAICEuseFluxForm=T)
232      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
233          for standard fwd & AD lab_sea tests (to keep the same output).
234    o pkg/seaice/seaice_growth.F:
235      - use Ian Fenty's capping formulas for actual ice
236      thickness thoughout EVOLUTION branch.
237      - put treatment pathological case #2) in CPP brackets
238      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
239      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
240    o pkg/seaice:
241      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
242      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
243      also pass fac as a param, which can be 1. (to update the tendency
244      field) or the time step (to update the field itself).
245      - seaice_advdiff.F: for multidim, call seaice_diffusion with
246      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
247      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
248      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
249      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
250    o pkg/seaice:
251      diffusion with centered advection scheme (diffus.F & advect.F):
252      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
253        to just compute the laplacian of input-field.
254      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
255      - fix flux-form version in diffus.F to conserve tracer.
256      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
257       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
258    
259    checkpoint62y (2011/05/26)
260    o pkg/seaice:
261     - seaice_growth.F : in EVOLUTION branch, always include
262       a_QSWbyATM_cover in qnet (as it should be).
263     - verification/global_ocean.cs32x15 : update results accordingly
264       (output.seaice.txt output_adm.seaice.txt).
265    o pkg/seaice + obcs:
266     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
267       equivalent of assuming no tracer gradient outside the OB region.
268       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
269     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
270       after changes above);
271     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
272       only at OB location (instead of over a band of OLx width).
273    o pkg/seaice:
274     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
275       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
276  o pkg/obcs:  o pkg/obcs:
277    - split header file "OBCS.h" into 4 separated files:    - split header file "OBCS.h" into 4 separated files:
278      OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h      OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
279     Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h     Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
280       (contain no conditional statement that depends on OBCS options).       (contain no conditional statement which depends on OBCS options).
281      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
282        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
283  o ctrl, cost, grdchk & autodiff pkgs:  o ctrl, cost, grdchk & autodiff pkgs:
284    - make options file more standard (like other {PKG}_OPTIONS.h file but    - make options file more standard (like other {PKG}_OPTIONS.h file but
285      with AD_CONFIG.h); clean-up some of the included header files.      with AD_CONFIG.h); clean-up some of the included header files.
