4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o adjoint verifications
8      - changed 5 experiments to multi-threaded
9        * global_ocean.90x40x15
10        * obcs_ctrl
11        * offline_exf_seaice
12        * tutorial_dic_adjoffline
13        * tutorial_tracer_adjsens
14        changed reference output for those that crossed tile boundaries
15        (changed choices of gradient check positions)
16      - temporary bug fix in grdchk_loc.F for obcs
17    
18    o genmake2 & testreport
19      - add target "obj" (just for OBJFILES files) to Makefile;
20      - add option to specify FEXTRAFLAGS on command line.
21    o pkg/mypackage:
22      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
23    
24    checkpoint63a (2011/08/02)
25    o pkg/diagnostics (velocity potential):
26      - fix velocity-potential calculation when using OBCS: balance net inflow
27        at each level (new S/R OBCS_DIAG_BALANCE).
28      - fix some of the problems with OBCS in stream-function calculation.
29    o pkg/exf/exf_readparms.F
30      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
31        EXF_NML_OBCS) more consistent, so that you need not have these lists
32        in data.exf when they are not used.
33    o optim/optim_readdata.F:
34      - add some output about obcs variables that might help debugging
35      - add a check about nvarlength
36    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
37    o pkg/diagnostics (velocity potential):
38      - fix mask for OBCS (still problems in stream-function with OBCS);
39      - add specific parameter (default = main code CG2D params) for solver;
40      - in case of poor convergence, use solution corresponding to lowest residual.
41    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
42      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
43      and should be avoided where possible.
44    o model/src (rStar):
45      - include r* effect on reference-state (PhiRef) in totPhiHyd
46        (so that it's really the potential anomaly at the cell center);
47        affect solution only if z* with full pressure in EOS.
48      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
49        update output (because of z* in totPhiHyd and viscA4 changes);
50      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
51        @ constant r) until interpolation at constant r is implemented.
52    o pkg/diagnostics
53      - fix RCENTER diagnostics in case cell center is not at interface middle
54    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
55      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
56      that THETA and SALT are "conservative temperature" and "absolute
57      salinity"
58    o pkg/ctrl
59      - fix computation of endrec in s/r ctrl_init_rec
60      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
61    o pkg/seaice/seaice_growth.F
62      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
63        remove then obsolete STORE directives
64      - fix STORE directives for tice and tices, so that only the
65        appropriate part of the fields are stored (and not the entire
66        field); update global_ocean.cs32x15.seaice AD output.
67      - cosmetic changes: adjust CPP flags and indentation for better
68        legibilty
69    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
70      Chris Wilson)
71    o pkg/gmredi:
72       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
73       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
74    
75    checkpoint63  (2011/07/11)
76    o pkg/exch2:
77     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
78     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
79       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
80       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
81    o pkg/diagnostics:
82     - deal with pairs of post-processed diags which are computed together; in
83       particular, re-order list of diags within 1 file to save 2nd computation.
84     - add S/R to compute velocity stream-function (called after velocity-potential
85       calculation) from divergence free transport -> new diagnostics "PsiVEL".
86     - add parameter to select grid-point location where PsiVEL == 0.
87    o eesupp/src:
88       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
89       (specific S/R needed with exch2 topology - for now, just print an error msg)
90    o pkg/shelfice
91     - Implement friction velocity-dependent transfer coefficients following
92       Holland and Jenkins, JPO, 1999
93       Original code by M. Losch with small modifs.
94       Enable with CPP option SHI_ALLOW_GAMMAFRICT
95       and runtime flag SHELFICEuseGammaFrict
96    o verification lab_sea & global_ocean.cs32x15:
97     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
98       does not miss some dependencies (but is slower) and also works with many files
99       (default makedepend limitation for AD built).
100     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
101    o pkg/diagnostics:
102     - add run-time parameter "useMissingValue" (def=False) to fill land-point
103        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
104       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
105     - Extend the use of "missing_value" setting from data.diagnostics for the case
106       of counter-diagnostics (where fraction-weight is zero). This applies both to
107       MNC and MDS output files.
108    o pkg/seaice/seaice_growth.F:
109      - add 'a priori' cap of latent heat flux based on actual mass considerations
110        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
111        non-legacy seaice_solve4temp.
112      - add diagnostic of the residual sublimation freshwater flux (the freshwater
113        flux taken from the ocean if the total actual latent heat fluxes exceed
114        the maximum)
115      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
116       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
117      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
118       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
119      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
120      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
121    o verification 1D_ocean_ice_column:
122       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
123       update results
124    o pkg/diagnostics:
125     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
126       which are not filled-up but computed from other diags ; In this case, the mate
127       diag points to the primary (filled-up) diag to used for post processing.
128     - Update Velocity-potential computation using post-processed diag framework.
129     ==> Change the ordering of fields and time-periods in MDS output file
130       when using periodic averaging: now writes one time record with the full set
131       of fields for this time period, then the next time reccord (it used to be
132       one field with the full set of time records then the next field).
133         Note: this is now similar to NetCDF (MNC) output file. <==
134    
135    checkpoint62z (2011/06/21)
136    o adjoint monitor:
137     - Add adjoint monitor output for packages exf, seaice
138       and update relevant testreport output
139    o pkg/seaice:
140     - re-order diags inits so that they appear in order in available_diagnostics.log
141     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
142       area/heff/hsnow preceeding thermodynamic growth/melt.
143     - modified diag: SIdA; output actual effect, as the description states.
144     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
145     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
146       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
147        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
148     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
149     - added diagnostics for seaice generic tracers (SItr*).
150     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
151     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
152     I. Fenty: 18-Jun-2011:
153     Minor changes to seaice package:
154     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
155        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
156       - Differentiated "regularization variables" from "floor variables"
157        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
158        * hiceMin became SEAICE_hice_reg (old hiceMin)
159          (with _reg meaning regularization variable)
160       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
161        so as to ensure energy conservation when going between phases
162      - A22 was not used anywhere
163     2) Changed regularization procedure for heffActual and hsnowActual to ensure
164        well-boundedness and smooth adjoint in seaice_growth.F
165     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
166        because the old regularization always set heffActual >= 0.05 cm
167     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
168        on AREA when HEFF > 0.
169      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
170        requiring that DISABLE_AREA_FLOOR *not* be defined
171     Affected verifications:
172      - 1D_ocean_ice_column (output.txt output_adm.txt)
173      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
174    o pkg/diagnostics:
175      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
176      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
177        (was _RL, now integer) with option = 0 to retrieve all levels.
178      - add pieces of code to compute velocity potential at each level (new diagnostics
179        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
180        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
181      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
182        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
183        and in diagnostics_fract_fill.F (do not need a valid pointer for the
184        diagnostics counter-mate); check that definition of counter-diagnostic
185        includes a valid counter-mate (in diagnostics_set_levels.F).
186    o model/src (rStar):
187      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
188        affect solution only if z* with full pressure in EOS;
189        update output of test-exp global_ocean.90x40x15.
190    o pkg/seaice:
191      - introduce siEps=1e-5 parameter
192      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
193      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
194      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
195        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
196        as well as ice cover age and ridging index (attached to AREA).
197        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
198        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
199        Up to SItrMaxNum=3 tracers can be used simultaneously.
200    o pkg/salt_plume:
201      -introduce SPsalFRAC run time parameter that sets the fraction of the
202       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
203       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
204    o model debug options:
205      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
206        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
207      - Refine debug-msg printing selection (3 new levels):
208        debugMode  : controls printing of debug messages (sequence of S/R calls).
209        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
210         debLevZero =  0 ; /* level of disabled aux. msg printing */
211         debLevA =  1 ; /* level of minimum  aux. msg printing */
212         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
213         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
214         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
215         debLevE =  5 ; /* level of extensive debug printing */
216        New debugLevel default: with default debugMode value (=F),
217          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
218          and if debugMode=T, default debugLevel = 4 (debLevD).
219        Relation with previous settings:
220         debLevB (=2) corresponds to former debLevA (=1)
221         debLevD (=4) corresponds to former debLevB (=2)
222        Note:
223         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
224         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
225            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
226      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
227        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
228    o pkg/obcs:
229      - change OBCSfixTopo default from True to False (should not change the results);
230        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
231    o pkg/thsice:
232      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
233        2nd layer seaice sublimation (unlikely to happen)
234      - use Interior mask for OBCS in thsice_advection.F (similar to what is
235        done in gad_advection & seaice_advection).
236    o adjoint:
237      bug fix spotted by Gael Forget:
238      seaice_advection and thsice_advection still had
239      legacy CPP options to avoid CS corner updates for adjoint
240    o pkg/seaice:
241      => Change some of the defaults (2011/05/29):
242         - change SEAICEuseFluxForm default (from False to True)
243         - change DIFF1 default (from 0.004 m/s to 0. m/s)
244         And print warnings if DIFF1 is not set in data.seaice and centered
245          avection scheme is used without any diffusion.
246      also:
247      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
248      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
249      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
250        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
251        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
252      update results of test exp.:
253         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
254             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
255             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
256         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
257         seaice_obcs: output (SEAICEuseFluxForm=T)
258      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
259          for standard fwd & AD lab_sea tests (to keep the same output).
260    o pkg/seaice/seaice_growth.F:
261      - use Ian Fenty's capping formulas for actual ice
262      thickness thoughout EVOLUTION branch.
263      - put treatment pathological case #2) in CPP brackets
264      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
265      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
266    o pkg/seaice:
267      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
268      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
269      also pass fac as a param, which can be 1. (to update the tendency
270      field) or the time step (to update the field itself).
271      - seaice_advdiff.F: for multidim, call seaice_diffusion with
272      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
273      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
274      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
275      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
276    o pkg/seaice:
277      diffusion with centered advection scheme (diffus.F & advect.F):
278      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
279        to just compute the laplacian of input-field.
280      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
281      - fix flux-form version in diffus.F to conserve tracer.
282      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
283       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
284    
285    checkpoint62y (2011/05/26)
286    o pkg/seaice:
287     - seaice_growth.F : in EVOLUTION branch, always include
288       a_QSWbyATM_cover in qnet (as it should be).
289     - verification/global_ocean.cs32x15 : update results accordingly
290       (output.seaice.txt output_adm.seaice.txt).
291    o pkg/seaice + obcs:
292     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
293       equivalent of assuming no tracer gradient outside the OB region.
294       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
295     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
296       after changes above);
297     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
298       only at OB location (instead of over a band of OLx width).
299    o pkg/seaice:
300     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
301       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
302    o pkg/obcs:
303      - split header file "OBCS.h" into 4 separated files:
304        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
305       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
306         (contain no conditional statement which depends on OBCS options).
307      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
308        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
309    o ctrl, cost, grdchk & autodiff pkgs:
310      - make options file more standard (like other {PKG}_OPTIONS.h file but
311        with AD_CONFIG.h); clean-up some of the included header files.
312    o pkg/obcs:
313      - do not mask tracer when applying OB (tracer == 0 could generate problems)
314      - apply tracer OB values to tracer field only at OB location (instead of
315        over a band of OLx width)
316      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
317      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
318        obcs_apply_tloc.F & obcs_apply_sloc.F
319    o obcs in model/src:
320      - call OBCS_APPLY_W only if NonHydrostatic.
321      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
322      - reset dEtaHdt and wVel to zero outside OB interior region ;
323      - leave tracer unchanged outside OB interior region: This has no effect
324        on the solution but just to prevent unrealistic tracer value outside OB.
325      - zero out velocity outside OB interior region: This has no effect on
326        the solution but just to prevent unrealistic velocity outside OB.
327    o obcs and non-lin free-surf:
328       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
329       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
330       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
331       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
332       update results of test-exp. exp4(nlfs).
333    o exp4 (nlfs) test-exp:
334       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
335       with NonLin-FreeSurf); update output.nlfs.txt
336    o obcs and 2d/3d solver norm:
337       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
338       and outside OB interior region (will allow to place OB further inside the
339       domain). Depending on the domain, can affects cg2d-Norm (previous
340       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
341       and cg3d-Norm (previous Norm was computed before canceling OB terms),
342       e.g. in tutorial_plume_on_slope.
343      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
344    o pkg rbcs:
345      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
346      - add capability to apply relaxation to horizontal velocity uVel & vVel.
347    o pkg/grdchk: add gradient check for control variable xx_shifwflx
348    o pkg/shelfice/shelfice_init_fixed.F
349      fix CPP-flag combinations
350    o pkg/seaice: Merge iceage code of Pierre Rampal
351      * update/change/correct ice age calculations
352      * add age updates for pathological cases
353      Probably needs more testing...
354    
355    checkpoint62x (2011/05/13)
356    o pkg/mom_vecinv:
357       high-order vorticity scheme: use interior masks (maskInW & S)
358       to zero-out (outside OB) gradient of vorticity.
359    o verification exp.:
360       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
361       hs94.128x64x5 and seaice_obcs ; update results.
362    o pkg/obcs:
363      fix bug in OBeta for YZ sections in obcs_exf_load.F
364    o pkg/ctrl, pkg/shelfice, and optim:
365      - add new control variable xx_shifwflx (fresh water flux underneath ice
366        shelves). This is almost as tedious as obcs-ctrl, because the
367        variables needs its own mask.
368      - add a cost function term that penalizes the deviation of xx_shifwflx
369        from the first guess (zero) in analogy to other control variables
370    o pkg/shelfice:
371      - start basic adjoint
372    o pkg/ctrl:
373      - remove extra 2D field "for good measure" when initializing in
374        ctrl_set_globfld_[xy/xz/yz].F
375      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
376      - improve error messages in ctrl_set_unpack_*
377    o OBC implementation in momentum:
378       use interior masks (maskInC,W & S) in momentum S/R:
379       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
380       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
381       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
382       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
383       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
384        (and also with Leith/Smagorinsky harmonic-viscosity).
385       Update output of experiment dome and exp4 (+nlfs).
386    o exp4 test-exp:
387      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
388        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
389        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
390        time-varying OB at Western-side for wVel (NonHyd); update output.
391      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
392        and biharmonic-viscosity ; also use prescribed time varying OB.
393    o pkg/obcs:
394      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
395    o model/src:
396      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
397      - initialise startTime & nIter0 with unlikely values: allows to set one
398        from the other without ambiguity.
399    o seaice_obcs test-exp.:
400      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
401    o pkg/obcs:
402      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
403        no longer needed with maskInC,W,S in pkg/generic_advdiff.
404    o pkg/seaice:
405      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
406        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
407      - fixed bug in the initialization of sea ice salinity variable HSALT
408        in seaice_init_varia.F  (removed dependence on ICE2WATR)
409    o fizhi-cs test exp.:
410       switch reference output convention for these 2 non-standard test-exp,
411        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
412          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
413       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
414    o model/inc:
415      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
416        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
417    o pkg/seaice:
418      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
419    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
420      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
421        and initial HSALT
422    
423    checkpoint62w (2011/04/26)
424    o pkg/mom_fluxform:
425      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
426      - use parameter "sideDragFactor" in no-slip BC side-drag part.
427      - update output of exp. global_ocean.90x40x15
428    o pkg/mom_vecinv:
429      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
430    o update seaice exp.:
431      use more consistent parameter values (remove "backward compatability only":
432       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
433      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
434       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
435    o update test-exp global_ocean.90x40x15:
436      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
437      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
438      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
439      o turn on zStar & viscA4 in standard set-up (dir input/)
440        and update output files: output.txt & output.dwnslp.txt
441    o new AD-test experiment: obcs_ctrl
442      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
443    o pkg/dic:
444      fix two bugs in handling water vapour pressure in carbonate chemistry
445      and air-sea fluxes. Found by Val Bennington and Galen McKinley
446      (add DIC Option = WATERVAP_BUG to recover old results)
447      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
448    o adding allowInteriorFreezing option to check for water below freezing point
449      at depth and bring the negative heat anomaly to the surface level
450    o pkgs _fields_load:
451      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
452      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
453        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
454        rbcs to get interpolation weights and time reccord number.
455      - fix multi-threading in aim_fields_load.F
456      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
457    o external_fields_load:
458      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
459       interpolation weights) to use in a periodic time-series ; do not divide by
460       time-step to convert to integer:
461       - this fixes case where externForcingPeriod is not multiple of time-step
462          (Thanks to Christopher L. Wolfe)
463       - this fixes case where externForcingPeriod is an odd multiple of time-step
464         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
465      store index of time-record which is currently loaded:
466       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
467       - needed for the adjoint but not yet used because of extensive recomputations;
468         (to be fixed soon)
469    
470    checkpoint62v (2011/04/02)
471    o verification/1D_ocean_ice_column added to test Ian Fenty's
472      pkg/seaice_growth.F modifications for improving sea ice code differentiability
473    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
474      (new velocity statistics after changing maskInW & maskInS definition)
475    o pkg/generic_advdiff with OBCS:
476      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
477      equivalent to assumption of no tracer gradient outside the OB region.
478      This will affect the results if using obcs+biharmonic diffusion.
479      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
480    o pkg/obcs:
481      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
482      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
483      in Interior region. No impact on solution but affects Velocity monitor stats.
484    o pkg/ptracers (adjoint)
485      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
486      tape file for each tracer
487    o model/inc/src and pkg/autodiff: add parameters that allow to turn
488      of parts of the adjoint code at run time. For now, there are only
489      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
490      parameters are set in data.pkg.
491      This is the lazy coward's version of doing this, but still useful for
492      debugging. In order to do it right, everything needs to be moved to
493      pkg/autodiff.
494    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
495      the end; this fixes the adjoint balancing code for open boundaries.
496    o pkg/ctrl:
497      - change behavior of xx_${varname}period to be analogous to exf-conventions:
498        xx_${varname}period =   0.,  means time-independent control part
499        xx_${varname}period = -12., means one-year-periodic monthly control part
500      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
501        clean up ctrl_init a little, remove unused variables
502      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
503      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
504    
505    checkpoint62u (2011/03/15)
506    o model/src:
507      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
508        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
509      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
510        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
511    o pkg/ctrl/obcs/ecco:
512      - remove obsolete, unused, and partially broken code:
513        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
514        ALLOW_CTRL_OBCS_BALANCE
515      - put a stop statement into ecco/cost_obcsvol.F, but also add
516        cost_obcsvol to ecco_ad_diff.list
517    o pkg/ecco: fix counting cost function contributions for obcs (code
518      by Matt M.) and diffkr for diagnostics
519    o pkg/ecco, pkg/ctrl, pkg/grdchk:
520      add cost penalty terms for initial uvel, vvel, eta controls
521      and I/O for prior error files
522    o pkg/mdsio:
523       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
524       (new argument) to check for tiled file in mdsioLocalDir : this fix the
525       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
526    o pkg/ctrl:
527     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
528       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
529       unused and superfluous variables
530     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
531    o pkg/ecco
532     - enable adjoint of Stevens OB
533    o pkg/ctrl/ecco/grdchk:
534      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
535        Fortunately, we do not have any tests for the numerous cpp-flagged
536        option of "obcs as control parameters" so we will never know
537        if this is an improvement (but at least now things compile).
538      - remove an obsolete initialization from ecco_cost_init_barfiles.F
539      - fix some problems within never used ifdefs to make the code compile
540    o pkg/obcs:
541     - Refine Interior mask definition to work with more complex OB (e.g.
542       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
543       read in Interior mask from file. Check if Interior mask is consistent
544       with OB list of indices.
545    o pkg/seaice
546     - beginning code for a seaice tracer package,
547       but currently only used for seaice age: SEAICE_AGE
548       SEAICE_num = 4
549       iTracer = 1: area-weighted ice age
550               = 2: volume-weighted ice age
551               = 3, 4: template for one-year vs. multi-year ice
552       data.seaice has new namelist SEAICE_PARM03 for arrays related to
553       SEAICE_num
554    
555    checkpoint62t (2011/03/05)
556    o pkg/obcs:
557     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
558       then normal component. This ensures that the normal component is set
559       correctly even when it conficts with tangential setting from an other OB.
560       Affects results of test-experiment seaice_obcs: update the output.txt
561    o pkg/obcs:
562     - add code to monitor statistics of dynamical fields at OB.
563     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
564       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
565       - change default: balance the Net inflow through all OB (instead of balancing
566         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
567     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
568       to match Nortern OB inflow (OBCS_balanceFacN=0).
569    o pkg/seaice:
570     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
571    o pkg/seaice (seaice_growth v 1.113):
572     - reverting seaice_growth to v 1.111 in order to have code with exact bit
573       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
574       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
575       runtime flag SEAICEareaFormula is kept but is inactive
576    o model/src:
577     - add new param to scale curvilinear grid distance and area when using
578       a different sphere radius from the grid-files.
579     - test/check multi-threads EXCH applied to local variable (cg2d_x)
580    o adjoint:
581     - enable adjoint of Stevens OB
582     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
583       (a bit delicate because of potentially modified adj. common block structure;
584       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
585    
586    checkpoint62s (2011/02/15)
587    o pkg/seaice (seaice_growth v 1.112):
588     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
589       computing the ice cover tendency from effective thickness tendencies. Include
590       Ian Fenty's formula.
591     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
592       SEAICEareaFormula.
593     - simplify notations for the various d_HEFF/d_AREA terms.
594    o pkg/gmredi:
595     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
596       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
597       add a verification test-run (front_relax.bvp) to test GM_useBVP.
598    o pkg/seaice (seaice_growth v 1.111):
599     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
600     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
601       also melt ice.
602    o pkg/seaice:
603     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
604     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
605    o pkg/cheapaml:
606     - from Nico Wienders: New version of this package.
607    o pkg/flt:
608     - add CPP options to prevent floats to re-enter the opposite side of
609       a periodic domain (default: keep periodicity)
610    o pkg/gmredi:
611     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
612       (needed for multi-dim advection).
613     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
614    o model/src:
615     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
616    o tutorial_tracer_adjsens
617     - extend to NLFS and replace maskC by hFacC
618       (change reference output accordingly)
619    
620    checkpoint62r (2011/01/24)
621    o testreport:
622     - add option -deloutp (-do) to remove output file after successful run
623     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
624       extract exact list of procs from this file ; adjust COMMAND by
625       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
626    o pkg/ecco: replace old ineffective way of penalizing deviations from
627      first guess (of obcs) with code by Matt Mazloff
628    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
629      exf/cal
630      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
631        and handle case of obcs?period == 0
632        Not affected by these changes: There is still an inconsistency in
633        the computation of start/endrec for the obcs variables for ALLOW_CAL
634        defined (see comment by Menemenlis, 7-Mar-2003)
635      - make S/R ctrl_get_gen_rec return something meaningful even if
636        ALLOW_CAL is not defined
637      - ctrl_getobcs?: simplify code so that it does not need to use
638                       S/R exf_swapfields
639    o testreport:
640       allow to test MPI with different number of processors for each experiment:
641       create file "SIZE.h.mpi" in each build dir.
642       Note: update of "-command" argument not yet implemented.
643    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
644      alleviate the need for additional 3D tapes when using
645      the non-inear free surface in the adjoint. This is done
646      by adding an 'update' of hfacc etc. to their current
647      value at the beginning of forward_step.F.
648    o pkg/seaice
649      seaice_lsr: move stress-divergence computations out of outer pseudo-
650      timestepping loop
651    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
652      up, so that the calls of the ctrl_* subroutines are really at the end
653      of the routine.
654    o pkg/gmredi:
655      allow to specify a 2-D horizontal map and a 1-D vertical profil
656      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
657    o pkg/seaice:
658      move lsr iterations from seaice_dynsolver to seaice_lsr.
659    o pkg/seaice:
660      reduce memory footprint of seaice mutldim advection tapes,
661      by using a 2D tape independent of the generic_advdiff ones,
662      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
663    
664    checkpoint62q (2010/12/29)
665    o model/src:
666      - check horizontal grid-spacing for unset or zero/negative values.
667      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
668    o pkg/flt:
669      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
670      - precision of input and output files set according to readBinaryPrec
671        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
672      - initial float position from tiled file was not converted to index space
673        (looks like a bug): fixed to make it similar to initial pos. global file.
674    o global_ocean.cs32x15:
675       change SIZE.h of AD set-up to get same tiling as with MPI.
676       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
677    o model/src:
678       add flag to control printing of domain fields (bathymetry, hFac ...) in
679       ini_mask_etc (call to plot_fieds_xy*).
680    o pkg/thsice:
681       if useEXF, some forcing fields are not valid in overlap: fixed by computing
682       over the interior only + apply EXCH at the end (like with SEAICE advection).
683    o pkg/mdsio:
684      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
685        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
686      - change barrier call for safe multi-threads access to 3-D shared buffer.
687      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
688      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
689        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
690    o pkg/flt:
691      - add fourth-order Runge-Kutta integration
692      - add basic exch2 support (only 1 facet supported so far!)
693    o pkg/mdsio+rw:
694      new S/R to read local (or tile independent) vector (read counterpart of
695       mds_writevec_loc, and front-end write_glvec_rl/rs).
696    o global_ocean.cs32x15: additional input_ad.seaice experiment
697        that uses pkg/seaice rather than pkg/thsice.
698        (using multidim advection for seaice)
699    o towards more F95 syntax for array specification in namelist:
700      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
701        of all verification experiments.
702           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
703          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
704      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
705    o global_ocean.cs32x15: additional input.seaice experiment
706        that uses pkg/seaice rather than pkg/thsice.
707    
708    checkpoint62p (2010/12/17)
709    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
710        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
711    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
712        allow for use of multim. advection in seaice adjoint.
713    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
714      - first attempt to close budgets by taking into account the freshwater
715        flux implied by the sublimation of snow and ice. So far only the
716        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
717        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
718    o eesupp/src:
719      new S/R with new option (NML_EXTENDED_F77) to change array specification
720      from F95 standard to commonly accepted extended F77 form.
721      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
722      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
723      for less tolerant f77 compiler (e.g., pgf77, g77).
724    o globalFiles:
725      commented out in parameter file "data" since it's not safe with MPI
726      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
727      in this case); no longer commented out in restart test (tst_2+2).
728    o add adTapeDir to specify a special directory where adjoint tapes are
729      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
730      and cannot be used together with mdsioLocalDir.
731    o nesting pkgs:
732      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
733      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
734      - add parameter files + utils dir + output from short run on beagle.
735    o pkg/seaice:
736        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
737    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
738      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
739    
740    checkpoint62o (2010/11/25)
741    o pkg/exf:
742      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
743    o pkg/seaice:
744      - seaice_ocean_stress: split a loop for better vectorization of the
745        adjoint code
746      - seaice_growth.F: fix bug in conservation of freshwater connected to
747        capping of heff, put contribution into d_HEFFbyNEG
748      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
749        by something more sensible (parameters that are what their name implies)
750      - change some defaults, so that by default exf-parameters are used for
751        things like rhoAir, cpAir,latent/sensible heat parameters, in order
752        to reproduce the old results, many data.seaice now contain funny values
753        for cpAir and latent heat of sublimation
754    o packages_readparms.F: move exf_readparms up in line so that
755        exf-parameters are visible for other packages (e.g. seaice)
756    o debugMode & debugLevel=2:
757      - differentiate between debugMode & debugLevel=2:
758        debugMode: controls printing of debug messages (sequence of S/R calls).
759        debugLevel: controls printing of algorithm intermediate results and stats.
760      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
761        => allows to print debug-stats without all sequence of call messages.
762      - switch control of debug print from debugLevel to debugMode in many S/R.
763    o pkg/obcs (obcs-sponge):
764        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
765        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
766    o pkg/generic_advdiff:
767      - record overlap minimum size for each advection scheme;
768      - refine criteria on overlap minimum size;
769      - check and stop (in gad_check) if overlap size is too small.
770    o pkg/obcs:
771      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
772        once, in ptracers_implicit.F)
773      - with seaice: remove test on empty file name in obcs_apply_seaice (always
774        apply OB values when tile has OB)
775    o model/src, coriolis setting:
776      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
777        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
778        files (selectCoriMap=3) with any grid.
779      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
780    o pkg/seaice/seaice_growth.F:
781        a few cosmetic changes that reduce the number of lines of code
782    o pkg/obcs: add boundary conditions following Stevens (1990)
783      - the code follows old MOM/NAOSIM code
784      - so far it is only implemented for the eastern and western boundaries
785        and NOT for pTracers
786    o pkg/rbcs:
787      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
788        beginning of the first rbcs forcing period.
789      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
790        offline package, i.e., one file per time, labeled by iteration number;
791        deltaTrbcs sets the timestep with which the data was generated;
792        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
793      - rbcsForcingCycle=0 makes forcing non-cyclic.
794      - make arithmetic safe for negative times and odd forcing periods.
795    
796    checkpoint62n (2010/11/09)
797    o pkg/seaice:
798        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
799    o pkg/obcs:
800       New S/R to copy tracer value from the OB location to narrow band region
801        (width = same as overlap) beyond the OB: preserve OB value (needed for
802        high-order scheme) which were overwritten by EXCH call if in overlap
803        region. Applied to theta, salt, ptracer and advected seaice variables.
804       With seaice: use maskInC in similar way as in gad_advection.F,
805        in seaice_advection.F and advect.F.
806       Update output of experiment seaice_obcs and change exp4 to test OBCS with
807        4th order Adv.Scheme. for pasive salt and ptracer.
808    o tools/genmake2:
809      - when looking for an optfile (not specified), only search for Fortran compiler
810        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
811      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
812        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
813      - set default for CPP to "cpp -traditional -P" (was the case without specifying
814        an optfile, but otherwise default was just "cpp".
815      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
816      - when "CC" is not set in the optfile, look for possible C compiler
817        (instead of just setting CC=cc)
818      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
819        => add a ".F" to ".o" rule for source files with no "#include" (such as
820           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
821      - move gfortran before g77 in list of possible Fortran compiler (consistent
822        with reference compiler switch from g77 to gfortran)
823    o pkg/seaice:
824      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
825        seaice_check that stops the model, when the CPP flag is used.
826      o seaice_growth.F: make capping of ice volume conserving by returning the
827        capped ice as freshwater to EmPmR. This does not change the verification
828        experiments but will change runs where the capping is acutally active
829    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
830      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
831         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
832         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
833    o tools/genmake2:
834      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
835      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
836      - clean previous genmake log files before anything else.
837      - change Makefile to remove testreport log files (*.tr_log) and genmake log
838        files only with "CLEAN" target (instead of "Clean");
839    o pkg/generic_advdiff:
840      Change OBCS in multiDim advection (gad_advection.F):
841       Use maskInC to prevent intermediate update of tracer-field in OB regions,
842       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
843       which were applying future time-step OB values.
844      This way, all explicit calculations use current-time-step OB values
845       (simpler and more consistent).
846      Affects results when set-up uses time-varying OBC and multi-dim advection;
847       update output of experiment seaice_obcs.
848    o pkg/seaice:
849      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
850       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
851         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
852      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
853       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
854       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
855    o pkg aim (2010/10/26):
856      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
857        formulation with obliquity, eccentricity, ... as run-time parameters,
858      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
859        upward shortwave radition at the surface (all-sky and clear-sky).
860    o pkg/obcs:
861      - writing sections with globalFiles=T does not work: switch to tiled-files
862        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
863      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
864      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
865    
866    checkpoint62m (2010/10/21)
867    o pkg/seaice: vectorize seaice_solve4temp.F
868      - move iterations loops outside of i/j-loops
869      - requires 2D arrays for TB and effConduct
870      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
871        modified in this routine
872      - a little bit of clean up, adjusting indentation, etc.
873      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
874        performance and '**TWO' by '**2' (because TWO is a float),
875        replaced ONE, ZERO
876    o eesupp/src:
877       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
878    o pkg/seaice/seaice_growth.F
879      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
880      merging process. The merged routine has two branches, and one activates the 'evolution'
881      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
882      In summary, here is what the '10/10 revision' did consist of
883        part 1: seaice_growth.F revisions 1.71 to 1.75
884          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
885            The emphasis here was on improving readability (e.g. by trying to use meaningful
886            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
887        part 1.5:
888          - revising the lab_sea experiment to make it a more useful (i.e. stable
889            and representative of an actual model run). This was done by generating a
890            (winter) pickup to start from, switching back the main experiment dynamic
891            solver from evp to lsr, having one of the experiments use the free drift solution.
892        part 2: seaice_growth.F revisions 1.76 to 1.85
893          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
894          - Sorting out the various fields units and sign (set early on and reset at the end)
895            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
896            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
897          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
898            and simplifying logical expressions to further improve readibility.
899        part 3: seaice_growth.F revisions 1.86 to 1.89
900          - Re-organize the blocks of code more logically.
901          - Merging the '_if.F' pieces that add something new.
902    o pkg/thsice:
903      - vectorize thsice_solve4temp and thsice_get_exf.
904        Problem: thsice_solve4temp has an unvectorizable statement that
905        might also be problematic for TAF
906      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
907        does not change the verifcation experiment, but will change all
908        experiments that have this flag undefined (not tested in verification);
909        a little reorganization to save a few 2D fields and recomputations
910      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
911      - 2nd step:  fix some store dirs
912        o seems to work somewhat, i.e. using ifort but not g77
913        o likely cause are incomplete init. or recomputation
914        o start verification/global_ocean.cs32x15/input_ad.thsice
915    o pkg/obcs: add support for exch2
916      - the position of the boundary and prescribed values are specified using
917        a global domain with exch2 facets stacked
918        - in x for N,S boundaries (like W2_mapIO=-1)
919        - in y for E,W boundaries (so E,W boundaries do not overlap)
920    o pkg/mdsio: add support for writing global sections with exch2
921        file layout is as for obcs described above:
922        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
923        - for y-z sections, facets are stacked in y
924    o pkg/thsice:
925       - change a few routines for better vectorization: thsice_albedo.F,
926         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
927         not affected, but in particular the latter routine has changed
928         dramatically (not necessarily easier to read now).
929       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
930       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
931    o verification/lab_sea:
932      - overhaul of the forward model experiments. The main motivation
933        for this revision is that lab_sea has proven quite fragile (when
934        changing the sea-ice code, and switching platforms) to a point
935        when failures were very hard to attribute to specific code problems.
936      - the suspected reason for this fragility is noise amplification by evp so,
937        to start with, we decided to replace evp with lsr in the main experiment.
938      - the input.lsr experiment thus became obsolete and was removed.
939      - it was replaced with the input.fd experiment that uses an
940        analytical "free drift" solution as the ice velocity field.
941      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
942        will hopefully allow us to discriminate problems due to dynamic solvers
943        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
944        us to test additional options, along with the salt plume package.
945      - Finally a pickup was generated (at the end of a one year run) to
946        make the tests more representative of an actual model run. Previously
947        the tests starting point was a 1m thickness of ice everywhere.
948    o pkg/seaice:
949      - introducing S\R seaice_freedrift.F that compute the
950        analytical solution to an approximate ice momentum
951        equation (i.e. the simple stress/coriolis balance).
952      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
953        of the free drift velocity field, and enable its use.
954        To actually use the free drift solution as the model ice
955        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
956    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
957    
958    checkpoint62l (2010/10/04)
959    o pkg/seaice:
960      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
961      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
962       version (with USE_ORIGINAL_SBI undef);
963    o add hooks for new packages OASIS, the package will follow
964      (hooks exclude the seaice pkg for now)
965    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
966      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
967      rather than mdsio_readvector.F/mdsio_writevector.F, within
968      adread_adwrite.F to read/write adjoint-related tapes to disk.
969    o eesupp and pkg/mdsio: ALLOW_WHIO
970      Option to write/read 2D fields to files including tiles halos.
971      The main purpose is for adjoint related "tape I/O".
972      The secondary purpose is for debugging phases.
973      A word on those rather specifically intended purposes.
974      The code was meant to be stripped down to the bare minimum.
975      Typically, there is a unique and basic mapping to the global
976      buffer (tile by tile, then proc by proc, then level by level), and
977      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
978      meant to generate user friendly outputs of various shapes and forms.
979      Rather it is intended, for the knowledgeabale developers,
980      to be largely independent of the many mdsio options, to allow
981      outputs of tiles+halos in debugging phases and in adjoint runs,
982      and to allow some flexibility in tuning (adoint) I/O depending on each
983      file system behavior. With regard to tuning, most of the potential knobs
984      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
985      to specify directories, to specify the typical size of I/O calls, etc.)
986      are not yet included, and will be added if they prove useful.
987    o pkg/seaice:
988       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
989    o pkg/seaice:
990       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
991       code (seaice_budget_ice_if.F) which enable to recover old standard
992       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
993       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
994    o model/src (rStar):
995       use simple average (not area weighted) of rStarFac at U,V point when using
996       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
997       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
998    
999    checkpoint62k (2010/09/17)
1000    o adjoint
1001       * changed verification/global_ocean.cs32x15 ; adjoint now tests
1002         Adams-Bashforth 3 + NLFS + RSTAR
1003       * some more modifs required for ECCO-GODAE v4
1004    o pkg/seaice
1005       add SEAICE_AGE_VOL option to use volume instead of area for
1006       integrating SEAICE_AGE
1007  o model/src:  o model/src:
1008     first check-in of sigma & hybrid-sigma coordinate code ; also includes     first check-in of sigma & hybrid-sigma coordinate code ; also includes
