4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src:
8      - move bi,bj loops inside INTEGR_CONTINUITY ;
9      - call INTEGR_CONTINUITY directly from forward_step.F
10        (previously called from momentum_correction_step.F)
11      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
12        forward_step.F and pkg/ecco/the_main_loop.F
13    o model/src/do_oceanic_phys.F:
14      - reset addMass to zero only if useICEFRONT ;
15      - separated k-loop for rhoInSitu calculation ;
16      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
17        and at constant T,S (= WdRHOdP);
18      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
19        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
20        transport of locally-referenced potential density);
21        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
22    o gluemnc:
23      - replace ncrcat with ncks when adding variables to *.glob.nc
24      - change the way variables without record dimensions are handled so that
25        files that have variables with and without record variables can be glued:
26        add a record dimension with a new unique name to be able to differentiate
27        between variable with and without a-prior record dimensions. Remove
28        this record dimension before adding the variable to the *.glob.nc file.
29        This procedure automatically works also for grid.*.nc files that do not
30        have any record dimension.
31    o verification/cpl_aim+ocn:
32      - generate new reference output on baudelaire (gfortran, mpich2) (previously
33        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
34    o pkg/obcs/obcs_calc_stevens.F:
35      - add code for northern and southern boundaries.
36      - reorder some loops to save some operations and so that drFBar can be scalar
37    o model/src:
38      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
39        truncation) and add diagnostics for Adams-Bashforth tendency increment.
40      - update test-exp. AD output:
41        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
42      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
43        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
44        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
45        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
46        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
47        tutorial_plume_on_slope.
48    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
49      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
50      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
51      does not even come with an F77 compiler anymore, this should not be
52      a limitation
53    
54    checkpoint63e (2011/11/06)
55    o pkg/seaice adjoint of LSR:
56      - substantially rework STORE dirs.
57      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
58        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
59        and only perform SOLV_MAX_FIXED adjoint iters.
60        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
61        always goes to same record, meaning that the last forward field will be
62        the one used in the adjoint - an approximation.
63      - now produces non-zero LSR-related gradients, and acceptable gradients for
64        An's zonal (x-z) test case (to be checked in)
65      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
66        (but these are screwed up by the thermodynamics in the first place);
67        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
68        output_adm.txt also reflects changes to seaice_lsr
69      - global_ocean.cs32x15:
70        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
71          (output_adm.seaice.txt was updated)
72        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
73          (output_adm.seaice_dynmix.txt)
74    o test-exp. exp4+stevens:
75      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
76    o pkg/seaice (lsr solver):
77      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
78        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
79      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
80      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
81        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
82      - compute (with new S/R) and print initial (+ free-driff sol. if available)
83        and final residual of linearised system.
84    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
85      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
86    o pkg/obcs: Stevens BCs (still only for east and west)
87      - fix Stevens BCs by using intermediate velocities of previous
88        time step as "baroclinic" contribution rather velocity of one grid cell
89        inside the boundaries; more consistent but makes the entire treatment
90        more complicated, requires new pickup files and two new S/Rs:
91        obcs_copy_uv_n and obcs_save_uv_n
92        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
93        (undefined by default)
94      - silently move computation of some grid factors into separate loops to
95        save some recomputations
96      - add a hack for non-linear free surface
97      - add a verification experiment to exp4 that tests this code
98    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
99    
100    checkpoint63d (2011/10/25)
101    o pkg/obcs + seaice-dynamics:
102      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
103        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
104        values (consistent with an implicit method).
105      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
106        return to older implementation (same results as before); note that none of
107        the "experimental" OBCS_SEAICE options are implemented in the new version.
108      - switch test exp. seaice_obcs to use new version (update output).
109    o pkg/seaice:
110      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
111      - add parenthesis in Water-Ice drag calculations (evp & lsr);
112      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
113        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
114      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
115        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
116    o pkg/layers:
117      - Include potential density as new coordinate (Thanks to David Munday)
118    o pkg/dic:
119      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
120        carbonate computation/output to CALC_PCO2_APPROX
121    o pkg/generic_advdiff
122      - make TAF generate code that vectorizes:
123        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
124    o model/src:
125      - improve vectorization also for adjoint code of
126        solve_tridiagonal and solve_pentadiagonal. As this requires up to
127        5 new 3D-fields, this code is only turned on for the combination of
128        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
129        for singular matrix check (only for TARGET_NEC_SX).
130      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
131        ALLOW_AUTODIFF. This flag now needs to be set outside of
132        solve_tri/pentadiagonal.F
133    o pkg/exf:
134      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
135        optional namelist EXF_NML_OBCS).
136      - add many debug-print (to trace down where pkg/cal error msg comes from)
137    o pkg/mom_vecinv/mom_vi_hdissip.F
138      - rearrange loops so that vectorization is improved and in particular
139        the adjoint routine vectorizes. The code is a little longer now, but I
140        think easier to read.
141        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
142    o pkg/seaice:
143      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
144    o pkg/exch2:
145      - alternative code (without tile x tile matrix) for cumulated (global) sum;
146        used as default; keep using matrix version in adjustment.cs-32x32x1.
147    o tools/build_options:
148      - after merging some MPI and/or multi-threads specific optfiles so that
149        the modified default optfile support both built (using genmake2 -mpi
150        for the MPI built, using genmake2 -omp for OpenMP built),
151        move now obsolete optfiles to tools/build_options/unsupported/
152       (add copy of email sent to support list in doc/optfiles_changes.txt)
153    
154    checkpoint63c (2011/09/28)
155    o pkg/ebm:
156      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
157        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
158    o pkg/seaice (SItracer pickup)
159    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
160      To be done:
161      - thorough testing of missing fields in S/R seaice_read_pickup
162      - thorough matching between generic tracers and specific fields used
163        (e.g. volume-weighted age, area-weighted age, salinity, ...)
164    o pkg/grdchk:
165      - all procs calculate and print finite-difference gradient (for testreport)
166      - change description output used by testreport;
167      - AD testing: also compare and report Finite-difference gradient;
168        => update all output_adm*.txt
169    o test exp. global_ocean_ebm:
170      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
171        and turn on exactConserve; update (fwd) output.
172    o pkg/seaice (LSR):
173      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
174      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
175        * identical results with non-CS topology (but save up to half of EXCH calls)
176        * no much changes in cs-32 verification tests since no ice at face edges
177         (differences due to convergence criteria, since nb of iterations changed)
178        * expect some differences on lat-lon-cap grid.
179        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
180    o pkg/exch2:
181      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
182        many tiles); until alternative coding is added, just add a stop.
183    o pkg/kpp:
184      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
185        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
186    o optfiles:
187      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
188        into corresponding standard one, which now support different build:
189        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
190      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
191    o pkg/obcs (seaice):
192      - add missing EXCH for uIce,vIce after applying OBCS;
193      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
194        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
195        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
196      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
197      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
198        and eedata.mth for MPI and mutlti-threaded testing.
199    o pkg/flt:
200      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
201      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
202      - fix pickup and trajectories + profiles output with multi-threads;
203      - add parameter to select group of fields to write along trajectory and
204        profile (default unchanged);
205      - only call PORT_RAND* function when flt_noise <> 0;
206      - add multi-threaded test for verification exp. flt_example.
207    o eesupp/src:
208      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
209      - USE_OMP_THREADING: check that number of threads (from eedata) matches
210        actual number (from env.var. setting).
211    o pkg/ebm:
212      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
213      - add multi-threaded test for verification exp. global_ocean_ebm
214    
215    checkpoint63b (2011/08/29)
216    o pkg/ebm:
217      - fix sign of runoff;
218      - update directly forcing fields (Qnet,EmPmR) to use standard
219        external_forcing_surf.F (remove ebm_forcing_surf.F);
220      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
221      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
222        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
223      - update global_ocean_ebm parameters file data and update output (fwd+ad).
224    o verification/matrix_example:
225      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
226        MPI and mutlti-threaded testing.
227    o pkg/matrix:
228      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
229      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
230      - fix for multi-threaded (remove DATA statement);
231      - use standard DIFFERENT_MULTIPLE function;
232      - add MATRIX_OPTIONS.h
233    o verification/matrix_example:
234       To allow to split the domain in several tiles, change the domain size
235        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
236        Western side) of land points.
237    o (*_)write_pickup:
238      - fix few bugs in mypackage_read/write_pickup.F
239      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
240        array of length 1 (was caught by compiler syntax-check).
241    o pkg/diagnostics (velocity potential solver):
242      - fix initialisation of main diagonal matrix (for overlap values)
243    o tools/build_options:
244      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
245        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
246      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
247        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
248        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
249        and use "-devel" testreport option for standard testing on baudelaire.
250    o pkg/grdchk:
251      - Assume that all gradient-check position are within the same tile
252        corresponding to global indices (iGloTile,jGloTile) and that
253        positions (i,j indices or nbeg) are local to this tile;
254      - set tile local-indices and proc. number according to tile global-indices;
255      - remove grdchkwhichproc from namelist (retired param);
256      - send adjoint gradient to all procs so that all procs print it to STDOUT;
257      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
258    o adding package bbl (Bottom Boundary Layer)
259      description in MITgcm/pkg/bbl/bbl_description.tex
260      example/test experiment in MITgcm_contrib/bbl
261    o adjoint verifications
262      - changed 5 experiments to multi-tiles
263        * global_ocean.90x40x15
264        * obcs_ctrl
265        * offline_exf_seaice
266        * tutorial_dic_adjoffline
267        * tutorial_tracer_adjsens
268        changed reference output for those that crossed tile boundaries
269        (changed choices of gradient check positions)
270      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
271      - temporary bug fix in grdchk_loc.F for obcs
272    o genmake2 & testreport
273      - add target "obj" (just for OBJFILES files) to Makefile;
274      - add option to specify FEXTRAFLAGS on command line.
275    o pkg/mypackage:
276      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
277    
278    checkpoint63a (2011/08/02)
279    o pkg/diagnostics (velocity potential):
280      - fix velocity-potential calculation when using OBCS: balance net inflow
281        at each level (new S/R OBCS_DIAG_BALANCE).
282      - fix some of the problems with OBCS in stream-function calculation.
283    o pkg/exf/exf_readparms.F
284      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
285        EXF_NML_OBCS) more consistent, so that you need not have these lists
286        in data.exf when they are not used.
287    o optim/optim_readdata.F:
288      - add some output about obcs variables that might help debugging
289      - add a check about nvarlength
290    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
291    o pkg/diagnostics (velocity potential):
292      - fix mask for OBCS (still problems in stream-function with OBCS);
293      - add specific parameter (default = main code CG2D params) for solver;
294      - in case of poor convergence, use solution corresponding to lowest residual.
295    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
296      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
297      and should be avoided where possible.
298    o model/src (rStar):
299      - include r* effect on reference-state (PhiRef) in totPhiHyd
300        (so that it's really the potential anomaly at the cell center);
301        affect solution only if z* with full pressure in EOS.
302      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
303        update output (because of z* in totPhiHyd and viscA4 changes);
304      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
305        @ constant r) until interpolation at constant r is implemented.
306    o pkg/diagnostics
307      - fix RCENTER diagnostics in case cell center is not at interface middle
308    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
309      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
310      that THETA and SALT are "conservative temperature" and "absolute
311      salinity"
312    o pkg/ctrl
313      - fix computation of endrec in s/r ctrl_init_rec
314      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
315    o pkg/seaice/seaice_growth.F
316      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
317        remove then obsolete STORE directives
318      - fix STORE directives for tice and tices, so that only the
319        appropriate part of the fields are stored (and not the entire
320        field); update global_ocean.cs32x15.seaice AD output.
321      - cosmetic changes: adjust CPP flags and indentation for better
322        legibilty
323    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
324      Chris Wilson)
325    o pkg/gmredi:
326       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
327       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
328    
329    checkpoint63  (2011/07/11)
330    o pkg/exch2:
331     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
332     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
333       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
334       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
335    o pkg/diagnostics:
336     - deal with pairs of post-processed diags which are computed together; in
337       particular, re-order list of diags within 1 file to save 2nd computation.
338     - add S/R to compute velocity stream-function (called after velocity-potential
339       calculation) from divergence free transport -> new diagnostics "PsiVEL".
340     - add parameter to select grid-point location where PsiVEL == 0.
341    o eesupp/src:
342       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
343       (specific S/R needed with exch2 topology - for now, just print an error msg)
344    o pkg/shelfice
345     - Implement friction velocity-dependent transfer coefficients following
346       Holland and Jenkins, JPO, 1999
347       Original code by M. Losch with small modifs.
348       Enable with CPP option SHI_ALLOW_GAMMAFRICT
349       and runtime flag SHELFICEuseGammaFrict
350    o verification lab_sea & global_ocean.cs32x15:
351     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
352       does not miss some dependencies (but is slower) and also works with many files
353       (default makedepend limitation for AD built).
354     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
355    o pkg/diagnostics:
356     - add run-time parameter "useMissingValue" (def=False) to fill land-point
357        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
358       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
359     - Extend the use of "missing_value" setting from data.diagnostics for the case
360       of counter-diagnostics (where fraction-weight is zero). This applies both to
361       MNC and MDS output files.
362    o pkg/seaice/seaice_growth.F:
363      - add 'a priori' cap of latent heat flux based on actual mass considerations
364        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
365        non-legacy seaice_solve4temp.
366      - add diagnostic of the residual sublimation freshwater flux (the freshwater
367        flux taken from the ocean if the total actual latent heat fluxes exceed
368        the maximum)
369      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
370       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
371      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
372       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
373      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
374      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
375    o verification 1D_ocean_ice_column:
376       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
377       update results
378    o pkg/diagnostics:
379     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
380       which are not filled-up but computed from other diags ; In this case, the mate
381       diag points to the primary (filled-up) diag to used for post processing.
382     - Update Velocity-potential computation using post-processed diag framework.
383     ==> Change the ordering of fields and time-periods in MDS output file
384       when using periodic averaging: now writes one time record with the full set
385       of fields for this time period, then the next time reccord (it used to be
386       one field with the full set of time records then the next field).
387         Note: this is now similar to NetCDF (MNC) output file. <==
388    
389    checkpoint62z (2011/06/21)
390    o adjoint monitor:
391     - Add adjoint monitor output for packages exf, seaice
392       and update relevant testreport output
393    o pkg/seaice:
394     - re-order diags inits so that they appear in order in available_diagnostics.log
395     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
396       area/heff/hsnow preceeding thermodynamic growth/melt.
397     - modified diag: SIdA; output actual effect, as the description states.
398     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
399     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
400       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
401        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
402     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
403     - added diagnostics for seaice generic tracers (SItr*).
404     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
405     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
406     I. Fenty: 18-Jun-2011:
407     Minor changes to seaice package:
408     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
409        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
410       - Differentiated "regularization variables" from "floor variables"
411        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
412        * hiceMin became SEAICE_hice_reg (old hiceMin)
413          (with _reg meaning regularization variable)
414       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
415        so as to ensure energy conservation when going between phases
416      - A22 was not used anywhere
417     2) Changed regularization procedure for heffActual and hsnowActual to ensure
418        well-boundedness and smooth adjoint in seaice_growth.F
419     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
420        because the old regularization always set heffActual >= 0.05 cm
421     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
422        on AREA when HEFF > 0.
423      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
424        requiring that DISABLE_AREA_FLOOR *not* be defined
425     Affected verifications:
426      - 1D_ocean_ice_column (output.txt output_adm.txt)
427      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
428    o pkg/diagnostics:
429      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
430      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
431        (was _RL, now integer) with option = 0 to retrieve all levels.
432      - add pieces of code to compute velocity potential at each level (new diagnostics
433        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
434        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
435      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
436        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
437        and in diagnostics_fract_fill.F (do not need a valid pointer for the
438        diagnostics counter-mate); check that definition of counter-diagnostic
439        includes a valid counter-mate (in diagnostics_set_levels.F).
440    o model/src (rStar):
441      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
442        affect solution only if z* with full pressure in EOS;
443        update output of test-exp global_ocean.90x40x15.
444    o pkg/seaice:
445      - introduce siEps=1e-5 parameter
446      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
447      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
448      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
449        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
450        as well as ice cover age and ridging index (attached to AREA).
451        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
452        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
453        Up to SItrMaxNum=3 tracers can be used simultaneously.
454    o pkg/salt_plume:
455      -introduce SPsalFRAC run time parameter that sets the fraction of the
456       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
457       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
458    o model debug options:
459      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
460        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
461      - Refine debug-msg printing selection (3 new levels):
462        debugMode  : controls printing of debug messages (sequence of S/R calls).
463        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
464         debLevZero =  0 ; /* level of disabled aux. msg printing */
465         debLevA =  1 ; /* level of minimum  aux. msg printing */
466         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
467         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
468         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
469         debLevE =  5 ; /* level of extensive debug printing */
470        New debugLevel default: with default debugMode value (=F),
471          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
472          and if debugMode=T, default debugLevel = 4 (debLevD).
473        Relation with previous settings:
474         debLevB (=2) corresponds to former debLevA (=1)
475         debLevD (=4) corresponds to former debLevB (=2)
476        Note:
477         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
478         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
479            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
480      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
481        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
482    o pkg/obcs:
483      - change OBCSfixTopo default from True to False (should not change the results);
484        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
485    o pkg/thsice:
486      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
487        2nd layer seaice sublimation (unlikely to happen)
488      - use Interior mask for OBCS in thsice_advection.F (similar to what is
489        done in gad_advection & seaice_advection).
490    o adjoint:
491      bug fix spotted by Gael Forget:
492      seaice_advection and thsice_advection still had
493      legacy CPP options to avoid CS corner updates for adjoint
494    o pkg/seaice:
495      => Change some of the defaults (2011/05/29):
496         - change SEAICEuseFluxForm default (from False to True)
497         - change DIFF1 default (from 0.004 m/s to 0. m/s)
498         And print warnings if DIFF1 is not set in data.seaice and centered
499          avection scheme is used without any diffusion.
500      also:
501      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
502      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
503      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
504        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
505        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
506      update results of test exp.:
507         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
508             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
509             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
510         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
511         seaice_obcs: output (SEAICEuseFluxForm=T)
512      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
513          for standard fwd & AD lab_sea tests (to keep the same output).
514    o pkg/seaice/seaice_growth.F:
515      - use Ian Fenty's capping formulas for actual ice
516      thickness thoughout EVOLUTION branch.
517      - put treatment pathological case #2) in CPP brackets
518      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
519      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
520    o pkg/seaice:
521      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
522      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
523      also pass fac as a param, which can be 1. (to update the tendency
524      field) or the time step (to update the field itself).
525      - seaice_advdiff.F: for multidim, call seaice_diffusion with
526      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
527      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
528      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
529      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
530    o pkg/seaice:
531      diffusion with centered advection scheme (diffus.F & advect.F):
532      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
533        to just compute the laplacian of input-field.
534      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
535      - fix flux-form version in diffus.F to conserve tracer.
536      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
537       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
538    
539    checkpoint62y (2011/05/26)
540    o pkg/seaice:
541     - seaice_growth.F : in EVOLUTION branch, always include
542       a_QSWbyATM_cover in qnet (as it should be).
543     - verification/global_ocean.cs32x15 : update results accordingly
544       (output.seaice.txt output_adm.seaice.txt).
545    o pkg/seaice + obcs:
546     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
547       equivalent of assuming no tracer gradient outside the OB region.
548       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
549     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
550       after changes above);
551     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
552       only at OB location (instead of over a band of OLx width).
553    o pkg/seaice:
554     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
555       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
556    o pkg/obcs:
557      - split header file "OBCS.h" into 4 separated files:
558        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
559       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
560         (contain no conditional statement which depends on OBCS options).
561      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
562        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
563    o ctrl, cost, grdchk & autodiff pkgs:
564      - make options file more standard (like other {PKG}_OPTIONS.h file but
565        with AD_CONFIG.h); clean-up some of the included header files.
566    o pkg/obcs:
567      - do not mask tracer when applying OB (tracer == 0 could generate problems)
568      - apply tracer OB values to tracer field only at OB location (instead of
569        over a band of OLx width)
570      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
571      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
572        obcs_apply_tloc.F & obcs_apply_sloc.F
573    o obcs in model/src:
574      - call OBCS_APPLY_W only if NonHydrostatic.
575      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
576      - reset dEtaHdt and wVel to zero outside OB interior region ;
577      - leave tracer unchanged outside OB interior region: This has no effect
578        on the solution but just to prevent unrealistic tracer value outside OB.
579      - zero out velocity outside OB interior region: This has no effect on
580        the solution but just to prevent unrealistic velocity outside OB.
581    o obcs and non-lin free-surf:
582       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
583       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
584       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
585       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
586       update results of test-exp. exp4(nlfs).
587    o exp4 (nlfs) test-exp:
588       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
589       with NonLin-FreeSurf); update output.nlfs.txt
590    o obcs and 2d/3d solver norm:
591       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
592       and outside OB interior region (will allow to place OB further inside the
593       domain). Depending on the domain, can affects cg2d-Norm (previous
594       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
595       and cg3d-Norm (previous Norm was computed before canceling OB terms),
596       e.g. in tutorial_plume_on_slope.
597      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
598    o pkg rbcs:
599      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
600      - add capability to apply relaxation to horizontal velocity uVel & vVel.
601    o pkg/grdchk: add gradient check for control variable xx_shifwflx
602    o pkg/shelfice/shelfice_init_fixed.F
603      fix CPP-flag combinations
604    o pkg/seaice: Merge iceage code of Pierre Rampal
605      * update/change/correct ice age calculations
606      * add age updates for pathological cases
607      Probably needs more testing...
608    
609    checkpoint62x (2011/05/13)
610    o pkg/mom_vecinv:
611       high-order vorticity scheme: use interior masks (maskInW & S)
612       to zero-out (outside OB) gradient of vorticity.
613    o verification exp.:
614       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
615       hs94.128x64x5 and seaice_obcs ; update results.
616    o pkg/obcs:
617      fix bug in OBeta for YZ sections in obcs_exf_load.F
618    o pkg/ctrl, pkg/shelfice, and optim:
619      - add new control variable xx_shifwflx (fresh water flux underneath ice
620        shelves). This is almost as tedious as obcs-ctrl, because the
621        variables needs its own mask.
622      - add a cost function term that penalizes the deviation of xx_shifwflx
623        from the first guess (zero) in analogy to other control variables
624    o pkg/shelfice:
625      - start basic adjoint
626    o pkg/ctrl:
627      - remove extra 2D field "for good measure" when initializing in
628        ctrl_set_globfld_[xy/xz/yz].F
629      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
630      - improve error messages in ctrl_set_unpack_*
631    o OBC implementation in momentum:
632       use interior masks (maskInC,W & S) in momentum S/R:
633       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
634       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
635       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
636       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
637       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
638        (and also with Leith/Smagorinsky harmonic-viscosity).
639       Update output of experiment dome and exp4 (+nlfs).
640    o exp4 test-exp:
641      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
642        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
643        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
644        time-varying OB at Western-side for wVel (NonHyd); update output.
645      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
646        and biharmonic-viscosity ; also use prescribed time varying OB.
647    o pkg/obcs:
648      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
649    o model/src:
650      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
651      - initialise startTime & nIter0 with unlikely values: allows to set one
652        from the other without ambiguity.
653    o seaice_obcs test-exp.:
654      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
655    o pkg/obcs:
656      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
657        no longer needed with maskInC,W,S in pkg/generic_advdiff.
658    o pkg/seaice:
659      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
660        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
661      - fixed bug in the initialization of sea ice salinity variable HSALT
662        in seaice_init_varia.F  (removed dependence on ICE2WATR)
663    o fizhi-cs test exp.:
664       switch reference output convention for these 2 non-standard test-exp,
665        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
666          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
667       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
668    o model/inc:
