4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/gmredi:
8       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
9       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
10    
11    checkpoint63 (2011/07/11)
12    o pkg/exch2:
13     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
14     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
15       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
16       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
17    o pkg/diagnostics:
18     - deal with pairs of post-processed diags which are computed together; in
19       particular, re-order list of diags within 1 file to save 2nd computation.
20     - add S/R to compute velocity stream-function (called after velocity-potential
21       calculation) from divergence free transport -> new diagnostics "PsiVEL".
22     - add parameter to select grid-point location where PsiVEL == 0.
23    o eesupp/src:
24       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
25       (specific S/R needed with exch2 topology - for now, just print an error msg)
26    o pkg/shelfice
27     - Implement friction velocity-dependent transfer coefficients following
28       Holland and Jenkins, JPO, 1999
29       Original code by M. Losch with small modifs.
30       Enable with CPP option SHI_ALLOW_GAMMAFRICT
31       and runtime flag SHELFICEuseGammaFrict
32    o verification lab_sea & global_ocean.cs32x15:
33     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
34       does not miss some dependencies (but is slower) and also works with many files
35       (default makedepend limitation for AD built).
36     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
37    o pkg/diagnostics:
38     - add run-time parameter "useMissingValue" (def=False) to fill land-point
39        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
40       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
41     - Extend the use of "missing_value" setting from data.diagnostics for the case
42       of counter-diagnostics (where fraction-weight is zero). This applies both to
43       MNC and MDS output files.
44    o pkg/seaice/seaice_growth.F:
45      - add 'a priori' cap of latent heat flux based on actual mass considerations
46        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
47        non-legacy seaice_solve4temp.
48      - add diagnostic of the residual sublimation freshwater flux (the freshwater
49        flux taken from the ocean if the total actual latent heat fluxes exceed
50        the maximum)
51      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
52       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
53      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
54       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
55      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
56      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
57    o verification 1D_ocean_ice_column:
58       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
59       update results
60    o pkg/diagnostics:
61     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
62       which are not filled-up but computed from other diags ; In this case, the mate
63       diag points to the primary (filled-up) diag to used for post processing.
64     - Update Velocity-potential computation using post-processed diag framework.
65     ==> Change the ordering of fields and time-periods in MDS output file
66       when using periodic averaging: now writes one time record with the full set
67       of fields for this time period, then the next time reccord (it used to be
68       one field with the full set of time records then the next field).
69         Note: this is now similar to NetCDF (MNC) output file. <==
70    
71    checkpoint62z (2011/06/21)
72    o adjoint monitor:
73     - Add adjoint monitor output for packages exf, seaice
74       and update relevant testreport output
75    o pkg/seaice:
76     - re-order diags inits so that they appear in order in available_diagnostics.log
77     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
78       area/heff/hsnow preceeding thermodynamic growth/melt.
79     - modified diag: SIdA; output actual effect, as the description states.
80     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
81     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
82       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
83        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
84     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
85     - added diagnostics for seaice generic tracers (SItr*).
86     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
87     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
88     I. Fenty: 18-Jun-2011:
89     Minor changes to seaice package:
90     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
91        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
92       - Differentiated "regularization variables" from "floor variables"
93        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
94        * hiceMin became SEAICE_hice_reg (old hiceMin)
95          (with _reg meaning regularization variable)
96       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
97        so as to ensure energy conservation when going between phases
98      - A22 was not used anywhere
99     2) Changed regularization procedure for heffActual and hsnowActual to ensure
100        well-boundedness and smooth adjoint in seaice_growth.F
101     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
102        because the old regularization always set heffActual >= 0.05 cm
103     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
104        on AREA when HEFF > 0.
105      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
106        requiring that DISABLE_AREA_FLOOR *not* be defined
107     Affected verifications:
108      - 1D_ocean_ice_column (output.txt output_adm.txt)
109      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
110    o pkg/diagnostics:
111      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
112      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
113        (was _RL, now integer) with option = 0 to retrieve all levels.
114      - add pieces of code to compute velocity potential at each level (new diagnostics
115        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
116        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
117      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
118        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
119        and in diagnostics_fract_fill.F (do not need a valid pointer for the
120        diagnostics counter-mate); check that definition of counter-diagnostic
121        includes a valid counter-mate (in diagnostics_set_levels.F).
122    o model/src (rStar):
123      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
124        affect solution only if z* with full pressure in EOS;
125        update output of test-exp global_ocean.90x40x15.
126    o pkg/seaice:
127      - introduce siEps=1e-5 parameter
128      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
129      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
130      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
131        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
132        as well as ice cover age and ridging index (attached to AREA).
133        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
134        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
135        Up to SItrMaxNum=3 tracers can be used simultaneously.
136    o pkg/salt_plume:
137      -introduce SPsalFRAC run time parameter that sets the fraction of the
138       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
139       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
140    o model debug options:
141      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
142        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
143      - Refine debug-msg printing selection (3 new levels):
144        debugMode  : controls printing of debug messages (sequence of S/R calls).
145        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
146         debLevZero =  0 ; /* level of disabled aux. msg printing */
147         debLevA =  1 ; /* level of minimum  aux. msg printing */
148         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
149         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
150         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
151         debLevE =  5 ; /* level of extensive debug printing */
152        New debugLevel default: with default debugMode value (=F),
153          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
154          and if debugMode=T, default debugLevel = 4 (debLevD).
155        Relation with previous settings:
156         debLevB (=2) corresponds to former debLevA (=1)
157         debLevD (=4) corresponds to former debLevB (=2)
158        Note:
159         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
160         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
161            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
162      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
163        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
164    o pkg/obcs:
165      - change OBCSfixTopo default from True to False (should not change the results);
166        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
167    o pkg/thsice:
168      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
169        2nd layer seaice sublimation (unlikely to happen)
170      - use Interior mask for OBCS in thsice_advection.F (similar to what is
171        done in gad_advection & seaice_advection).
172    o adjoint:
173      bug fix spotted by Gael Forget:
174      seaice_advection and thsice_advection still had
175      legacy CPP options to avoid CS corner updates for adjoint
176    o pkg/seaice:
177      => Change some of the defaults (2011/05/29):
178         - change SEAICEuseFluxForm default (from False to True)
179         - change DIFF1 default (from 0.004 m/s to 0. m/s)
180         And print warnings if DIFF1 is not set in data.seaice and centered
181          avection scheme is used without any diffusion.
182      also:
183      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
184      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
185      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
186        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
187        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
188      update results of test exp.:
189         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
190             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
191             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
192         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
193         seaice_obcs: output (SEAICEuseFluxForm=T)
194      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
195          for standard fwd & AD lab_sea tests (to keep the same output).
196    o pkg/seaice/seaice_growth.F:
197      - use Ian Fenty's capping formulas for actual ice
198      thickness thoughout EVOLUTION branch.
199      - put treatment pathological case #2) in CPP brackets
200      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
201      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
202    o pkg/seaice:
203      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
204      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
205      also pass fac as a param, which can be 1. (to update the tendency
206      field) or the time step (to update the field itself).
207      - seaice_advdiff.F: for multidim, call seaice_diffusion with
208      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
209      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
210      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
211      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
212    o pkg/seaice:
213      diffusion with centered advection scheme (diffus.F & advect.F):
214      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
215        to just compute the laplacian of input-field.
216      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
217      - fix flux-form version in diffus.F to conserve tracer.
218      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
219       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
220    
221    checkpoint62y (2011/05/26)
222    o pkg/seaice:
223     - seaice_growth.F : in EVOLUTION branch, always include
224       a_QSWbyATM_cover in qnet (as it should be).
225     - verification/global_ocean.cs32x15 : update results accordingly
226       (output.seaice.txt output_adm.seaice.txt).
227    o pkg/seaice + obcs:
228     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
229       equivalent of assuming no tracer gradient outside the OB region.
230       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
231     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
232       after changes above);
233     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
234       only at OB location (instead of over a band of OLx width).
235    o pkg/seaice:
236     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
237       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
238    o pkg/obcs:
239      - split header file "OBCS.h" into 4 separated files:
240        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
241       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
242         (contain no conditional statement which depends on OBCS options).
243      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
244        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
245    o ctrl, cost, grdchk & autodiff pkgs:
246      - make options file more standard (like other {PKG}_OPTIONS.h file but
247        with AD_CONFIG.h); clean-up some of the included header files.
248    o pkg/obcs:
249      - do not mask tracer when applying OB (tracer == 0 could generate problems)
250      - apply tracer OB values to tracer field only at OB location (instead of
251        over a band of OLx width)
252      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
253      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
254        obcs_apply_tloc.F & obcs_apply_sloc.F
255    o obcs in model/src:
256      - call OBCS_APPLY_W only if NonHydrostatic.
257      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
258      - reset dEtaHdt and wVel to zero outside OB interior region ;
259      - leave tracer unchanged outside OB interior region: This has no effect
260        on the solution but just to prevent unrealistic tracer value outside OB.
261      - zero out velocity outside OB interior region: This has no effect on
262        the solution but just to prevent unrealistic velocity outside OB.
263    o obcs and non-lin free-surf:
264       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
265       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
266       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
267       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
268       update results of test-exp. exp4(nlfs).
269    o exp4 (nlfs) test-exp:
270       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
271       with NonLin-FreeSurf); update output.nlfs.txt
272    o obcs and 2d/3d solver norm:
273       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
274       and outside OB interior region (will allow to place OB further inside the
275       domain). Depending on the domain, can affects cg2d-Norm (previous
276       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
277       and cg3d-Norm (previous Norm was computed before canceling OB terms),
278       e.g. in tutorial_plume_on_slope.
279      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
280    o pkg rbcs:
281      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
282      - add capability to apply relaxation to horizontal velocity uVel & vVel.
283    o pkg/grdchk: add gradient check for control variable xx_shifwflx
284    o pkg/shelfice/shelfice_init_fixed.F
285      fix CPP-flag combinations
286    o pkg/seaice: Merge iceage code of Pierre Rampal
287      * update/change/correct ice age calculations
288      * add age updates for pathological cases
289      Probably needs more testing...
290    
291    checkpoint62x (2011/05/13)
292    o pkg/mom_vecinv:
293       high-order vorticity scheme: use interior masks (maskInW & S)
294       to zero-out (outside OB) gradient of vorticity.
295    o verification exp.:
296       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
297       hs94.128x64x5 and seaice_obcs ; update results.
298    o pkg/obcs:
299      fix bug in OBeta for YZ sections in obcs_exf_load.F
300    o pkg/ctrl, pkg/shelfice, and optim:
301      - add new control variable xx_shifwflx (fresh water flux underneath ice
302        shelves). This is almost as tedious as obcs-ctrl, because the
303        variables needs its own mask.
304      - add a cost function term that penalizes the deviation of xx_shifwflx
305        from the first guess (zero) in analogy to other control variables
306    o pkg/shelfice:
307      - start basic adjoint
308    o pkg/ctrl:
309      - remove extra 2D field "for good measure" when initializing in
310        ctrl_set_globfld_[xy/xz/yz].F
311      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
312      - improve error messages in ctrl_set_unpack_*
313    o OBC implementation in momentum:
314       use interior masks (maskInC,W & S) in momentum S/R:
315       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
316       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
317       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
318       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
319       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
320        (and also with Leith/Smagorinsky harmonic-viscosity).
321       Update output of experiment dome and exp4 (+nlfs).
322    o exp4 test-exp:
323      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
324        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
325        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
326        time-varying OB at Western-side for wVel (NonHyd); update output.
327      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
328        and biharmonic-viscosity ; also use prescribed time varying OB.
329    o pkg/obcs:
330      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
331    o model/src:
332      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
333      - initialise startTime & nIter0 with unlikely values: allows to set one
334        from the other without ambiguity.
335    o seaice_obcs test-exp.:
336      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
337    o pkg/obcs:
338      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
339        no longer needed with maskInC,W,S in pkg/generic_advdiff.
340    o pkg/seaice:
341      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
342        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
343      - fixed bug in the initialization of sea ice salinity variable HSALT
344        in seaice_init_varia.F  (removed dependence on ICE2WATR)
345    o fizhi-cs test exp.:
346       switch reference output convention for these 2 non-standard test-exp,
347        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
348          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
349       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
350    o model/inc:
351      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
352        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
353    o pkg/seaice:
354      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
355    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
356      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
357        and initial HSALT
358    
359    checkpoint62w (2011/04/26)
360    o pkg/mom_fluxform:
361      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
362      - use parameter "sideDragFactor" in no-slip BC side-drag part.
363      - update output of exp. global_ocean.90x40x15
364    o pkg/mom_vecinv:
365      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
366    o update seaice exp.:
367      use more consistent parameter values (remove "backward compatability only":
368       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
369      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
370       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
371    o update test-exp global_ocean.90x40x15:
372      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
373      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
374      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
375      o turn on zStar & viscA4 in standard set-up (dir input/)
376        and update output files: output.txt & output.dwnslp.txt
377    o new AD-test experiment: obcs_ctrl
378      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
379    o pkg/dic:
380      fix two bugs in handling water vapour pressure in carbonate chemistry
381      and air-sea fluxes. Found by Val Bennington and Galen McKinley
382      (add DIC Option = WATERVAP_BUG to recover old results)
383      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
384    o adding allowInteriorFreezing option to check for water below freezing point
385      at depth and bring the negative heat anomaly to the surface level
386    o pkgs _fields_load:
387      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
388      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
389        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
390        rbcs to get interpolation weights and time reccord number.
391      - fix multi-threading in aim_fields_load.F
392      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
393    o external_fields_load:
394      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
395       interpolation weights) to use in a periodic time-series ; do not divide by
396       time-step to convert to integer:
397       - this fixes case where externForcingPeriod is not multiple of time-step
398          (Thanks to Christopher L. Wolfe)
399       - this fixes case where externForcingPeriod is an odd multiple of time-step
400         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
401      store index of time-record which is currently loaded:
402       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
403       - needed for the adjoint but not yet used because of extensive recomputations;
404         (to be fixed soon)
405    
406    checkpoint62v (2011/04/02)
407    o verification/1D_ocean_ice_column added to test Ian Fenty's
408      pkg/seaice_growth.F modifications for improving sea ice code differentiability
409    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
410      (new velocity statistics after changing maskInW & maskInS definition)
411    o pkg/generic_advdiff with OBCS:
412      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
413      equivalent to assumption of no tracer gradient outside the OB region.
414      This will affect the results if using obcs+biharmonic diffusion.
415      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
416    o pkg/obcs:
417      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
418      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
419      in Interior region. No impact on solution but affects Velocity monitor stats.
420    o pkg/ptracers (adjoint)
421      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
422      tape file for each tracer
423    o model/inc/src and pkg/autodiff: add parameters that allow to turn
424      of parts of the adjoint code at run time. For now, there are only
425      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
426      parameters are set in data.pkg.
427      This is the lazy coward's version of doing this, but still useful for
428      debugging. In order to do it right, everything needs to be moved to
429      pkg/autodiff.
430    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
431      the end; this fixes the adjoint balancing code for open boundaries.
432    o pkg/ctrl:
433      - change behavior of xx_${varname}period to be analogous to exf-conventions:
434        xx_${varname}period =   0.,  means time-independent control part
435        xx_${varname}period = -12., means one-year-periodic monthly control part
436      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
437        clean up ctrl_init a little, remove unused variables
438      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
439      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
440    
441    checkpoint62u (2011/03/15)
442    o model/src:
443      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
444        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
445      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
446        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
447    o pkg/ctrl/obcs/ecco:
448      - remove obsolete, unused, and partially broken code:
449        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
450        ALLOW_CTRL_OBCS_BALANCE
451      - put a stop statement into ecco/cost_obcsvol.F, but also add
452        cost_obcsvol to ecco_ad_diff.list
453    o pkg/ecco: fix counting cost function contributions for obcs (code
454      by Matt M.) and diffkr for diagnostics
455    o pkg/ecco, pkg/ctrl, pkg/grdchk:
456      add cost penalty terms for initial uvel, vvel, eta controls
457      and I/O for prior error files
458    o pkg/mdsio:
459       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
460       (new argument) to check for tiled file in mdsioLocalDir : this fix the
461       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
462    o pkg/ctrl:
463     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
464       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
465       unused and superfluous variables
466     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
467    o pkg/ecco
468     - enable adjoint of Stevens OB
469    o pkg/ctrl/ecco/grdchk:
470      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
471        Fortunately, we do not have any tests for the numerous cpp-flagged
472        option of "obcs as control parameters" so we will never know
473        if this is an improvement (but at least now things compile).
474      - remove an obsolete initialization from ecco_cost_init_barfiles.F
475      - fix some problems within never used ifdefs to make the code compile
476    o pkg/obcs:
477     - Refine Interior mask definition to work with more complex OB (e.g.
478       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
479       read in Interior mask from file. Check if Interior mask is consistent
480       with OB list of indices.
481    o pkg/seaice
482     - beginning code for a seaice tracer package,
483       but currently only used for seaice age: SEAICE_AGE
484       SEAICE_num = 4
485       iTracer = 1: area-weighted ice age
486               = 2: volume-weighted ice age
487               = 3, 4: template for one-year vs. multi-year ice
488       data.seaice has new namelist SEAICE_PARM03 for arrays related to
489       SEAICE_num
490    
491    checkpoint62t (2011/03/05)
492    o pkg/obcs:
493     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
494       then normal component. This ensures that the normal component is set
495       correctly even when it conficts with tangential setting from an other OB.
496       Affects results of test-experiment seaice_obcs: update the output.txt
497    o pkg/obcs:
498     - add code to monitor statistics of dynamical fields at OB.
499     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
500       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
501       - change default: balance the Net inflow through all OB (instead of balancing
502         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
503     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
504       to match Nortern OB inflow (OBCS_balanceFacN=0).
505    o pkg/seaice:
506     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
507    o pkg/seaice (seaice_growth v 1.113):
508     - reverting seaice_growth to v 1.111 in order to have code with exact bit
509       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
510       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
511       runtime flag SEAICEareaFormula is kept but is inactive
512    o model/src:
513     - add new param to scale curvilinear grid distance and area when using
514       a different sphere radius from the grid-files.
515     - test/check multi-threads EXCH applied to local variable (cg2d_x)
516    o adjoint:
517     - enable adjoint of Stevens OB
518     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
519       (a bit delicate because of potentially modified adj. common block structure;
520       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
521    
522    checkpoint62s (2011/02/15)
523    o pkg/seaice (seaice_growth v 1.112):
524     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
525       computing the ice cover tendency from effective thickness tendencies. Include
526       Ian Fenty's formula.
527     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
528       SEAICEareaFormula.
529     - simplify notations for the various d_HEFF/d_AREA terms.
530    o pkg/gmredi:
531     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
532       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
533       add a verification test-run (front_relax.bvp) to test GM_useBVP.
534    o pkg/seaice (seaice_growth v 1.111):
535     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
536     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
537       also melt ice.
538    o pkg/seaice:
539     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
540     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
541    o pkg/cheapaml:
542     - from Nico Wienders: New version of this package.
543    o pkg/flt:
544     - add CPP options to prevent floats to re-enter the opposite side of
545       a periodic domain (default: keep periodicity)
546    o pkg/gmredi:
547     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
548       (needed for multi-dim advection).
549     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
550    o model/src:
551     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
552    o tutorial_tracer_adjsens
553     - extend to NLFS and replace maskC by hFacC
554       (change reference output accordingly)
555    
556    checkpoint62r (2011/01/24)
557    o testreport:
558     - add option -deloutp (-do) to remove output file after successful run
559     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
560       extract exact list of procs from this file ; adjust COMMAND by
561       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
562    o pkg/ecco: replace old ineffective way of penalizing deviations from
563      first guess (of obcs) with code by Matt Mazloff
564    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
565      exf/cal
566      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
567        and handle case of obcs?period == 0
568        Not affected by these changes: There is still an inconsistency in
569        the computation of start/endrec for the obcs variables for ALLOW_CAL
570        defined (see comment by Menemenlis, 7-Mar-2003)
571      - make S/R ctrl_get_gen_rec return something meaningful even if
572        ALLOW_CAL is not defined
573      - ctrl_getobcs?: simplify code so that it does not need to use
574                       S/R exf_swapfields
575    o testreport:
576       allow to test MPI with different number of processors for each experiment:
577       create file "SIZE.h.mpi" in each build dir.
578       Note: update of "-command" argument not yet implemented.
579    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
580      alleviate the need for additional 3D tapes when using
581      the non-inear free surface in the adjoint. This is done
582      by adding an 'update' of hfacc etc. to their current
583      value at the beginning of forward_step.F.
584    o pkg/seaice
585      seaice_lsr: move stress-divergence computations out of outer pseudo-
586      timestepping loop
587    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
588      up, so that the calls of the ctrl_* subroutines are really at the end
589      of the routine.
590    o pkg/gmredi:
591      allow to specify a 2-D horizontal map and a 1-D vertical profil
592      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
593    o pkg/seaice:
594      move lsr iterations from seaice_dynsolver to seaice_lsr.
595    o pkg/seaice:
596      reduce memory footprint of seaice mutldim advection tapes,
597      by using a 2D tape independent of the generic_advdiff ones,
598      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
599    
600    checkpoint62q (2010/12/29)
601    o model/src:
602      - check horizontal grid-spacing for unset or zero/negative values.
603      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
604    o pkg/flt:
605      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
606      - precision of input and output files set according to readBinaryPrec
607        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
608      - initial float position from tiled file was not converted to index space
609        (looks like a bug): fixed to make it similar to initial pos. global file.
610    o global_ocean.cs32x15:
611       change SIZE.h of AD set-up to get same tiling as with MPI.
612       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
613    o model/src:
614       add flag to control printing of domain fields (bathymetry, hFac ...) in
615       ini_mask_etc (call to plot_fieds_xy*).
616    o pkg/thsice:
617       if useEXF, some forcing fields are not valid in overlap: fixed by computing
618       over the interior only + apply EXCH at the end (like with SEAICE advection).
619    o pkg/mdsio:
620      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
621        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
622      - change barrier call for safe multi-threads access to 3-D shared buffer.
623      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
624      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
625        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
626    o pkg/flt:
627      - add fourth-order Runge-Kutta integration
628      - add basic exch2 support (only 1 facet supported so far!)
629    o pkg/mdsio+rw:
630      new S/R to read local (or tile independent) vector (read counterpart of
631       mds_writevec_loc, and front-end write_glvec_rl/rs).
632    o global_ocean.cs32x15: additional input_ad.seaice experiment
633        that uses pkg/seaice rather than pkg/thsice.
634        (using multidim advection for seaice)
635    o towards more F95 syntax for array specification in namelist:
636      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
637        of all verification experiments.
638           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
639          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
640      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
641    o global_ocean.cs32x15: additional input.seaice experiment
642        that uses pkg/seaice rather than pkg/thsice.
643    
644    checkpoint62p (2010/12/17)
645    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
646        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
647    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
648        allow for use of multim. advection in seaice adjoint.
649    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
650      - first attempt to close budgets by taking into account the freshwater
651        flux implied by the sublimation of snow and ice. So far only the
652        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
653        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
654    o eesupp/src:
655      new S/R with new option (NML_EXTENDED_F77) to change array specification
656      from F95 standard to commonly accepted extended F77 form.
657      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
658      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
659      for less tolerant f77 compiler (e.g., pgf77, g77).
660    o globalFiles:
661      commented out in parameter file "data" since it's not safe with MPI
662      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
663      in this case); no longer commented out in restart test (tst_2+2).
664    o add adTapeDir to specify a special directory where adjoint tapes are
665      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
666      and cannot be used together with mdsioLocalDir.
667    o nesting pkgs:
668      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
669      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
670      - add parameter files + utils dir + output from short run on beagle.
671    o pkg/seaice:
672        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
673    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
674      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
675    
676    checkpoint62o (2010/11/25)
677    o pkg/exf:
678      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
679    o pkg/seaice:
680      - seaice_ocean_stress: split a loop for better vectorization of the
681        adjoint code
682      - seaice_growth.F: fix bug in conservation of freshwater connected to
683        capping of heff, put contribution into d_HEFFbyNEG
684      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
685        by something more sensible (parameters that are what their name implies)
686      - change some defaults, so that by default exf-parameters are used for
687        things like rhoAir, cpAir,latent/sensible heat parameters, in order
688        to reproduce the old results, many data.seaice now contain funny values
689        for cpAir and latent heat of sublimation
690    o packages_readparms.F: move exf_readparms up in line so that
691        exf-parameters are visible for other packages (e.g. seaice)
692    o debugMode & debugLevel=2:
693      - differentiate between debugMode & debugLevel=2:
694        debugMode: controls printing of debug messages (sequence of S/R calls).
695        debugLevel: controls printing of algorithm intermediate results and stats.
696      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
697        => allows to print debug-stats without all sequence of call messages.
698      - switch control of debug print from debugLevel to debugMode in many S/R.
699    o pkg/obcs (obcs-sponge):
700        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
701        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
702    o pkg/generic_advdiff:
703      - record overlap minimum size for each advection scheme;
704      - refine criteria on overlap minimum size;
705      - check and stop (in gad_check) if overlap size is too small.
706    o pkg/obcs:
707      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
708        once, in ptracers_implicit.F)
709      - with seaice: remove test on empty file name in obcs_apply_seaice (always
710        apply OB values when tile has OB)
711    o model/src, coriolis setting:
712      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
713        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
714        files (selectCoriMap=3) with any grid.
715      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
716    o pkg/seaice/seaice_growth.F:
717        a few cosmetic changes that reduce the number of lines of code
718    o pkg/obcs: add boundary conditions following Stevens (1990)
719      - the code follows old MOM/NAOSIM code
720      - so far it is only implemented for the eastern and western boundaries
721        and NOT for pTracers
722    o pkg/rbcs:
723      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
724        beginning of the first rbcs forcing period.
725      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
726        offline package, i.e., one file per time, labeled by iteration number;
727        deltaTrbcs sets the timestep with which the data was generated;
728        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
729      - rbcsForcingCycle=0 makes forcing non-cyclic.
730      - make arithmetic safe for negative times and odd forcing periods.
731    
732    checkpoint62n (2010/11/09)
733    o pkg/seaice:
734        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
735    o pkg/obcs:
736       New S/R to copy tracer value from the OB location to narrow band region
737        (width = same as overlap) beyond the OB: preserve OB value (needed for
738        high-order scheme) which were overwritten by EXCH call if in overlap
739        region. Applied to theta, salt, ptracer and advected seaice variables.
740       With seaice: use maskInC in similar way as in gad_advection.F,
741        in seaice_advection.F and advect.F.
742       Update output of experiment seaice_obcs and change exp4 to test OBCS with
743        4th order Adv.Scheme. for pasive salt and ptracer.
744    o tools/genmake2:
745      - when looking for an optfile (not specified), only search for Fortran compiler
746        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
747      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
748        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
749      - set default for CPP to "cpp -traditional -P" (was the case without specifying
750        an optfile, but otherwise default was just "cpp".
751      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
752      - when "CC" is not set in the optfile, look for possible C compiler
753        (instead of just setting CC=cc)
754      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
755        => add a ".F" to ".o" rule for source files with no "#include" (such as
756           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
757      - move gfortran before g77 in list of possible Fortran compiler (consistent
758        with reference compiler switch from g77 to gfortran)
759    o pkg/seaice:
760      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
761        seaice_check that stops the model, when the CPP flag is used.
762      o seaice_growth.F: make capping of ice volume conserving by returning the
763        capped ice as freshwater to EmPmR. This does not change the verification
764        experiments but will change runs where the capping is acutally active
765    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
766      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
767         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
768         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
769    o tools/genmake2:
770      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
771      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
772      - clean previous genmake log files before anything else.
773      - change Makefile to remove testreport log files (*.tr_log) and genmake log
774        files only with "CLEAN" target (instead of "Clean");
775    o pkg/generic_advdiff:
776      Change OBCS in multiDim advection (gad_advection.F):
777       Use maskInC to prevent intermediate update of tracer-field in OB regions,
778       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
779       which were applying future time-step OB values.
780      This way, all explicit calculations use current-time-step OB values
781       (simpler and more consistent).
782      Affects results when set-up uses time-varying OBC and multi-dim advection;
783       update output of experiment seaice_obcs.
784    o pkg/seaice:
785      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
786       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
787         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
788      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
789       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
790       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
791    o pkg aim (2010/10/26):
792      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
793        formulation with obliquity, eccentricity, ... as run-time parameters,
794      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
795        upward shortwave radition at the surface (all-sky and clear-sky).
796    o pkg/obcs:
797      - writing sections with globalFiles=T does not work: switch to tiled-files
798        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
799      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
800      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
801    
802    checkpoint62m (2010/10/21)
803    o pkg/seaice: vectorize seaice_solve4temp.F
804      - move iterations loops outside of i/j-loops
805      - requires 2D arrays for TB and effConduct
806      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
807        modified in this routine
808      - a little bit of clean up, adjusting indentation, etc.
809      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
810        performance and '**TWO' by '**2' (because TWO is a float),
811        replaced ONE, ZERO
812    o eesupp/src:
813       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
814    o pkg/seaice/seaice_growth.F
815      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
816      merging process. The merged routine has two branches, and one activates the 'evolution'
817      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
818      In summary, here is what the '10/10 revision' did consist of
819        part 1: seaice_growth.F revisions 1.71 to 1.75
820          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
821            The emphasis here was on improving readability (e.g. by trying to use meaningful
822            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
823        part 1.5:
824          - revising the lab_sea experiment to make it a more useful (i.e. stable
825            and representative of an actual model run). This was done by generating a
826            (winter) pickup to start from, switching back the main experiment dynamic
827            solver from evp to lsr, having one of the experiments use the free drift solution.
828        part 2: seaice_growth.F revisions 1.76 to 1.85
829          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
830          - Sorting out the various fields units and sign (set early on and reset at the end)
831            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
832            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
833          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
834            and simplifying logical expressions to further improve readibility.
835        part 3: seaice_growth.F revisions 1.86 to 1.89
836          - Re-organize the blocks of code more logically.
837          - Merging the '_if.F' pieces that add something new.
838    o pkg/thsice:
839      - vectorize thsice_solve4temp and thsice_get_exf.
840        Problem: thsice_solve4temp has an unvectorizable statement that
841        might also be problematic for TAF
842      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
843        does not change the verifcation experiment, but will change all
844        experiments that have this flag undefined (not tested in verification);
845        a little reorganization to save a few 2D fields and recomputations
846      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
847      - 2nd step:  fix some store dirs
848        o seems to work somewhat, i.e. using ifort but not g77
849        o likely cause are incomplete init. or recomputation
850        o start verification/global_ocean.cs32x15/input_ad.thsice
851    o pkg/obcs: add support for exch2
852      - the position of the boundary and prescribed values are specified using
853        a global domain with exch2 facets stacked
854        - in x for N,S boundaries (like W2_mapIO=-1)
855        - in y for E,W boundaries (so E,W boundaries do not overlap)
856    o pkg/mdsio: add support for writing global sections with exch2
857        file layout is as for obcs described above:
858        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
859        - for y-z sections, facets are stacked in y
860    o pkg/thsice:
861       - change a few routines for better vectorization: thsice_albedo.F,
862         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
863         not affected, but in particular the latter routine has changed
864         dramatically (not necessarily easier to read now).
865       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
866       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
867    o verification/lab_sea:
868      - overhaul of the forward model experiments. The main motivation
869        for this revision is that lab_sea has proven quite fragile (when
870        changing the sea-ice code, and switching platforms) to a point
871        when failures were very hard to attribute to specific code problems.
872      - the suspected reason for this fragility is noise amplification by evp so,
873        to start with, we decided to replace evp with lsr in the main experiment.
874      - the input.lsr experiment thus became obsolete and was removed.
875      - it was replaced with the input.fd experiment that uses an
876        analytical "free drift" solution as the ice velocity field.
877      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
878        will hopefully allow us to discriminate problems due to dynamic solvers
879        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
880        us to test additional options, along with the salt plume package.
881      - Finally a pickup was generated (at the end of a one year run) to
882        make the tests more representative of an actual model run. Previously
883        the tests starting point was a 1m thickness of ice everywhere.
884    o pkg/seaice:
885      - introducing S\R seaice_freedrift.F that compute the
886        analytical solution to an approximate ice momentum
887        equation (i.e. the simple stress/coriolis balance).
888      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
889        of the free drift velocity field, and enable its use.
890        To actually use the free drift solution as the model ice
891        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
892    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
893    
894    checkpoint62l (2010/10/04)
895    o pkg/seaice:
896      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
897      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
898       version (with USE_ORIGINAL_SBI undef);
899    o add hooks for new packages OASIS, the package will follow
900      (hooks exclude the seaice pkg for now)
901    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
902      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
903      rather than mdsio_readvector.F/mdsio_writevector.F, within
904      adread_adwrite.F to read/write adjoint-related tapes to disk.
905    o eesupp and pkg/mdsio: ALLOW_WHIO
906      Option to write/read 2D fields to files including tiles halos.
907      The main purpose is for adjoint related "tape I/O".
908      The secondary purpose is for debugging phases.
909      A word on those rather specifically intended purposes.
910      The code was meant to be stripped down to the bare minimum.
911      Typically, there is a unique and basic mapping to the global
912      buffer (tile by tile, then proc by proc, then level by level), and
913      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
914      meant to generate user friendly outputs of various shapes and forms.
915      Rather it is intended, for the knowledgeabale developers,
916      to be largely independent of the many mdsio options, to allow
917      outputs of tiles+halos in debugging phases and in adjoint runs,
918      and to allow some flexibility in tuning (adoint) I/O depending on each
919      file system behavior. With regard to tuning, most of the potential knobs
920      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
921      to specify directories, to specify the typical size of I/O calls, etc.)
922      are not yet included, and will be added if they prove useful.
923    o pkg/seaice:
924       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
925    o pkg/seaice:
926       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
927       code (seaice_budget_ice_if.F) which enable to recover old standard
928       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
929       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
930    o model/src (rStar):
931       use simple average (not area weighted) of rStarFac at U,V point when using
932       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
933       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
934    
935    checkpoint62k (2010/09/17)
936    o adjoint
937       * changed verification/global_ocean.cs32x15 ; adjoint now tests
938         Adams-Bashforth 3 + NLFS + RSTAR
939       * some more modifs required for ECCO-GODAE v4
940    o pkg/seaice
941       add SEAICE_AGE_VOL option to use volume instead of area for
942       integrating SEAICE_AGE
943    o model/src:
944       first check-in of sigma & hybrid-sigma coordinate code ; also includes
945       non-linear free-surface parts ; but pressure-gradient not yet coded.
946    o pkg/ptracers:
947       option for ptracer to convert Salt Relax into additional EmP.
948        tested in exp. global_ocean.90x40x15.dwnslp (update output)
949    
950    checkpoint62j (2010/08/25)
951    o pkg/ggl90:
952       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
953    o pkg/dic: car_flux.F, phos_flux.F
954      - reduce number of exp-calls in order to improve performance
955      - clean up a little (replace fields by their macros, etc., fix
956        typo in CPP-flag)
957    o pkg/ggl90: minor changes
958      - GGL90diffKrS was removed --> always use GGL90diffKr
959      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
960      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
961        (commented out for now)
962      - change in max/min operations to ensure that smoothing is ok
963      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
964      - always use diffKrNrT as background profile (i.e. never use diffKr field)
965    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
966    o pkg/dic:
967      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
968        vectorization
969      - small bug fix in insol for the unlikely case of a cartesian grid
970      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
971        + now vectorize, which also removes adjoint recomputations;
972        + replace integer maksp1 by _RL maskp1
973        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
974    
975    checkpoint62i (2010/07/21)
976    o pkg/flt:
977      - with OBCS: stop floats which enter the OB region
978    o model/src:
979      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
980        for implicit vertical advection.
981    o pkg/seaice:
982     - account for melting in seaice age evolution.
983     - remove double counting of seaice ridging effect on seaice age.
984    
985    checkpoint62h (2010/06/18)
986    o pkg/exch2:
987     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
988    o tools/genmake2
989      - remove "-pdefault" option: redundant with the use of "packages.conf";
990      - remove file pkg/pkg_default : set the default as a pkg group
991        ("default_pkg_list") defined in pkg/pkg_groups;
992      - fix for case pkg/pkg_depend is missing (was hanging before);
993      - add option "-pgroups" to specify a different pkg_groups than the default.
994    o verification/adjustment.cs-32x32x1:
995       add a "minimal" set-up test (code_min & input_min) which only compiles
996       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
997    o tools/genmake2
998      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
999      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
1000    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
1001      files are nearly the same anyway.
1002      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
1003       - redefinition of tau(i,i) (by a factor of ustar)
1004       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
1005       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
1006       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
1007       - replace
1008         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
1009         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
1010         by
1011         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
1012         (changes results)
1013       -> exf_bulkformulae v1.22,
1014          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
1015          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
1016                    output.txt 1.63
1017           offline_exf_seaice: output.seaicetd.txt 1.7
1018           seaice_obcs: output.txt 1.10)
1019      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
1020       -> exf_bulkformulae v1.23,
1021          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
1022          and global_ocean.cs32x15.icedyn (only 11 matching digits)
1023      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
1024    o adjoint of exch-1:
1025     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
1026       (note: was already like this when using EXCH-2) and remove flow dir
1027       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
1028     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
1029     - update pkg/exch2 diff list.
1030    
1031    checkpoint62g (2010/05/19)
1032    o eesupp/src (exch-1):
1033     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
1034       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
1035       (renamed to exch1_*rx_cube.F).
1036     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
1037       to call new exch1 S/R ; update Makefile and .cvsignore.
1038     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
1039       exch2_xy_rx later)
1040      Note: after updating your code, need to run "make clean" in eesupp/src
1041    o test experiment bottom_ctrl_5x5:
1042       new output_adm.txt with fewer grdchk & less monitor output.
1043    o model/src:
1044      remove the call to ini_cori in initialise_varia.F (just keep the usual one
1045       in initialise_fixed.F). More consistent with coriolis & horizontal grid
1046       beeing treated in the same way (ini_grid is not called a 2nd time).
1047    o pkg/exf:
1048      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
1049      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
1050      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
1051      - cosmetic changes to exf_bulkformulae.F to make it look more like
1052        exf_bulk_largeyeager04.F
1053    o eesupp/src (exch-1):
1054      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
1055      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
1056        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
1057        (even without using MPI).
1058      - Message mode: move RecvAck setting (indicator of buffer being ready)
1059        from send_put to recv_get S/R (was useless before, but not sure if
1060        it's much more useful now);
1061      - Switch the order of sync: MPI-proc 1rst and then threads;
1062      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
1063      - fix AD code for communication mode ='get' (but not used).
1064    o model/src:
1065      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
1066      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
1067    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
1068    o pkg/ctrl: require a specific set of control variables and exf-flags for
1069      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
1070    o model/src:
1071     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
1072       1rst forward sweep, to avoid over-writing output files during recomputations
1073       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
1074     b) 2nd version:
1075      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
1076      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
1077         writePickupAtEnd) + seaice & ptracers output;
1078      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
1079    o model/src:
1080      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
1081    o pkg/exch2:
1082      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
1083      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
1084    o pkg/autodiff & exch2:
1085      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
1086      (for now, only if ALLOW_EXCH2 is defined).
1087    o pkg/autodiff:
1088      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
1089        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
1090       + clean-up comments (_RS is not always real*4)
1091      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
1092      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
1093        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
1094    o testreport (AD-tests):
1095      no longer link files from dir "../input" (1rst link files from
1096      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
1097    
1098    checkpoint62f (2010/04/29)
1099    o model/src/the_main_loop.F:
1100      adjust store directives for seaice evp and multicategory according to
1101      pkg/ecco/the_main_loop.F
1102    o adjoint:
1103      global_sum_ad was incomplete (noted many times by many people ;)
1104      nice description by Jean U. as follows:
1105      * allreduce(var) in global_sum.F can be interpreted as
1106        reduce(sum) followed by broadcast of sum.
1107      * The adjoint of that is
1108        sum(adjoint) followed by broadcast(summed adjoint value)
1109        or in other words, allreduce(sum, adjoint vars)
1110      We were missing the sum(adjoint)!
1111      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
1112      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
1113      The fix should produce 16-digit accuracy between
1114      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
1115      multi-CPU single-tile (e.g. nSx=1, nPx-2)
1116      We'll probably change this yet again shortly
1117    o eesupp/src:
1118      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
1119    o pkg/icefront
1120      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
1121        specification of addmass array based on a 2D field, which is added
1122        at bottommost wet level at each horizontal location.
1123    o model/src:
1124     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
1125     layout; (not always compatible with delX,delY setting; commented out for now).
1126    o pkg/exch2:
1127     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
1128     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
1129    
1130    checkpoint62e (2010/04/15)
1131    o pkg/obcs:
1132      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
1133    o pkg/dic:
1134      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
1135        (note: not presently tested in any forward verification exp.)
1136       update tutorial_global_oce_biogeo AD output file.
1137    o pkg/exf:
1138      - account for the variation of albedo as a function of zenith angle
1139        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
1140    o build_options:
1141     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
1142    o pkg/dic:
1143      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
1144      - use binary pickup file for restart;
1145      - initialise atmos-CO2 box from dic_pCO2 parameter;
1146      - fix multi-threaded.
1147    o pkg/rbcs:
1148     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
1149       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
1150     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
1151       and update output.txt
1152    o pkg/kpp:
1153     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
1154     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
1155       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
1156       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
1157     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
1158       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
1159    o pkg/offline:
1160      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
1161      (bug was added in version 1.10 on 2007-08-23).
1162    o pkg/offline:
1163      - no need to specify periodicExternalForcing, etc ... to use offline pack
1164      - offline input files no longer just single prec --> parameter offlineLoadPrec
1165  o verification/lab_sea:  o verification/lab_sea:
1166    change to multi-tile setup.    change AD test to multi-tile setup and update all 4 AD output.
