# Line 5  $Name$ Line 5  $Name$
5      ==============================      ==============================
6    
7  o model/src:  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:
669      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
670        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
671    o pkg/seaice:
672      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
673    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
674      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
675        and initial HSALT
676    
677    checkpoint62w (2011/04/26)
678    o pkg/mom_fluxform:
679      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
680      - use parameter "sideDragFactor" in no-slip BC side-drag part.
681      - update output of exp. global_ocean.90x40x15
682    o pkg/mom_vecinv:
683      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
684    o update seaice exp.:
685      use more consistent parameter values (remove "backward compatability only":
686       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
687      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
688       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
689    o update test-exp global_ocean.90x40x15:
690      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
691      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
692      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
693      o turn on zStar & viscA4 in standard set-up (dir input/)
694        and update output files: output.txt & output.dwnslp.txt
695    o new AD-test experiment: obcs_ctrl
696      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
697    o pkg/dic:
698      fix two bugs in handling water vapour pressure in carbonate chemistry
699      and air-sea fluxes. Found by Val Bennington and Galen McKinley
700      (add DIC Option = WATERVAP_BUG to recover old results)
701      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
702    o adding allowInteriorFreezing option to check for water below freezing point
703      at depth and bring the negative heat anomaly to the surface level
704    o pkgs _fields_load:
705      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
706      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
707        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
708        rbcs to get interpolation weights and time reccord number.
709      - fix multi-threading in aim_fields_load.F
710      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
711    o external_fields_load:
712      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
713       interpolation weights) to use in a periodic time-series ; do not divide by
714       time-step to convert to integer:
715       - this fixes case where externForcingPeriod is not multiple of time-step
716          (Thanks to Christopher L. Wolfe)
717       - this fixes case where externForcingPeriod is an odd multiple of time-step
718         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
719      store index of time-record which is currently loaded:
720       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
721       - needed for the adjoint but not yet used because of extensive recomputations;
722         (to be fixed soon)
723    
724    checkpoint62v (2011/04/02)
725    o verification/1D_ocean_ice_column added to test Ian Fenty's
726      pkg/seaice_growth.F modifications for improving sea ice code differentiability
727    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
728      (new velocity statistics after changing maskInW & maskInS definition)
729    o pkg/generic_advdiff with OBCS:
730      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
731      equivalent to assumption of no tracer gradient outside the OB region.
732      This will affect the results if using obcs+biharmonic diffusion.
733      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
734    o pkg/obcs:
735      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
736      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
737      in Interior region. No impact on solution but affects Velocity monitor stats.
738    o pkg/ptracers (adjoint)
739      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
740      tape file for each tracer
741    o model/inc/src and pkg/autodiff: add parameters that allow to turn
742      of parts of the adjoint code at run time. For now, there are only
743      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
744      parameters are set in data.pkg.
745      This is the lazy coward's version of doing this, but still useful for
746      debugging. In order to do it right, everything needs to be moved to
747      pkg/autodiff.
748    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
749      the end; this fixes the adjoint balancing code for open boundaries.
750    o pkg/ctrl:
751      - change behavior of xx_${varname}period to be analogous to exf-conventions:
752        xx_${varname}period =   0.,  means time-independent control part
753        xx_${varname}period = -12., means one-year-periodic monthly control part
754      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
755        clean up ctrl_init a little, remove unused variables
756      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
757      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
758    
759    checkpoint62u (2011/03/15)
760    o model/src:
761      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
762        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
763      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
764        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
765    o pkg/ctrl/obcs/ecco:
766      - remove obsolete, unused, and partially broken code:
767        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
768        ALLOW_CTRL_OBCS_BALANCE
769      - put a stop statement into ecco/cost_obcsvol.F, but also add
770        cost_obcsvol to ecco_ad_diff.list
771    o pkg/ecco: fix counting cost function contributions for obcs (code
772      by Matt M.) and diffkr for diagnostics
773    o pkg/ecco, pkg/ctrl, pkg/grdchk:
774      add cost penalty terms for initial uvel, vvel, eta controls
775      and I/O for prior error files
776    o pkg/mdsio:
777       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
778       (new argument) to check for tiled file in mdsioLocalDir : this fix the
779       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
780    o pkg/ctrl:
781     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
782       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
783       unused and superfluous variables
784     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
785    o pkg/ecco
786     - enable adjoint of Stevens OB
787    o pkg/ctrl/ecco/grdchk:
788      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
789        Fortunately, we do not have any tests for the numerous cpp-flagged
790        option of "obcs as control parameters" so we will never know
791        if this is an improvement (but at least now things compile).
792      - remove an obsolete initialization from ecco_cost_init_barfiles.F
793      - fix some problems within never used ifdefs to make the code compile
794    o pkg/obcs:
795     - Refine Interior mask definition to work with more complex OB (e.g.
796       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
797       read in Interior mask from file. Check if Interior mask is consistent
798       with OB list of indices.
799    o pkg/seaice
800     - beginning code for a seaice tracer package,
801       but currently only used for seaice age: SEAICE_AGE
802       SEAICE_num = 4
803       iTracer = 1: area-weighted ice age
804               = 2: volume-weighted ice age
805               = 3, 4: template for one-year vs. multi-year ice
806       data.seaice has new namelist SEAICE_PARM03 for arrays related to
807       SEAICE_num
808    
809    checkpoint62t (2011/03/05)
810    o pkg/obcs:
811     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
812       then normal component. This ensures that the normal component is set
813       correctly even when it conficts with tangential setting from an other OB.
814       Affects results of test-experiment seaice_obcs: update the output.txt
815    o pkg/obcs:
816     - add code to monitor statistics of dynamical fields at OB.
817     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
818       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
819       - change default: balance the Net inflow through all OB (instead of balancing
820         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
821     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
822       to match Nortern OB inflow (OBCS_balanceFacN=0).
823    o pkg/seaice:
824     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
825    o pkg/seaice (seaice_growth v 1.113):
826     - reverting seaice_growth to v 1.111 in order to have code with exact bit
827       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
828       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
829       runtime flag SEAICEareaFormula is kept but is inactive
830    o model/src:
831     - add new param to scale curvilinear grid distance and area when using
832       a different sphere radius from the grid-files.
833     - test/check multi-threads EXCH applied to local variable (cg2d_x)
834    o adjoint:
835     - enable adjoint of Stevens OB
836     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
837       (a bit delicate because of potentially modified adj. common block structure;
838       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
839    
840    checkpoint62s (2011/02/15)
841    o pkg/seaice (seaice_growth v 1.112):
842     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
843       computing the ice cover tendency from effective thickness tendencies. Include
844       Ian Fenty's formula.
845     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
846       SEAICEareaFormula.
847     - simplify notations for the various d_HEFF/d_AREA terms.
848    o pkg/gmredi:
849     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
850       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
851       add a verification test-run (front_relax.bvp) to test GM_useBVP.
852    o pkg/seaice (seaice_growth v 1.111):
853     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
854     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
855       also melt ice.
856    o pkg/seaice:
857     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
858     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
859    o pkg/cheapaml:
860     - from Nico Wienders: New version of this package.
861    o pkg/flt:
862     - add CPP options to prevent floats to re-enter the opposite side of
863       a periodic domain (default: keep periodicity)
864    o pkg/gmredi:
865     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
866       (needed for multi-dim advection).
867     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
868    o model/src:
869     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
870    o tutorial_tracer_adjsens
871     - extend to NLFS and replace maskC by hFacC
872       (change reference output accordingly)
873    
874    checkpoint62r (2011/01/24)
875    o testreport:
876     - add option -deloutp (-do) to remove output file after successful run
877     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
878       extract exact list of procs from this file ; adjust COMMAND by
879       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
880    o pkg/ecco: replace old ineffective way of penalizing deviations from
881      first guess (of obcs) with code by Matt Mazloff
882    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
883      exf/cal
884      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
885        and handle case of obcs?period == 0
886        Not affected by these changes: There is still an inconsistency in
887        the computation of start/endrec for the obcs variables for ALLOW_CAL
888        defined (see comment by Menemenlis, 7-Mar-2003)
889      - make S/R ctrl_get_gen_rec return something meaningful even if
890        ALLOW_CAL is not defined
891      - ctrl_getobcs?: simplify code so that it does not need to use
892                       S/R exf_swapfields
893    o testreport:
894       allow to test MPI with different number of processors for each experiment:
895       create file "SIZE.h.mpi" in each build dir.
896       Note: update of "-command" argument not yet implemented.
897    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
898      alleviate the need for additional 3D tapes when using
899      the non-inear free surface in the adjoint. This is done
900      by adding an 'update' of hfacc etc. to their current
901      value at the beginning of forward_step.F.
902    o pkg/seaice
903      seaice_lsr: move stress-divergence computations out of outer pseudo-
904      timestepping loop
905    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
906      up, so that the calls of the ctrl_* subroutines are really at the end
907      of the routine.
908    o pkg/gmredi:
909      allow to specify a 2-D horizontal map and a 1-D vertical profil
910      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
911    o pkg/seaice:
912      move lsr iterations from seaice_dynsolver to seaice_lsr.
913    o pkg/seaice:
914      reduce memory footprint of seaice mutldim advection tapes,
915      by using a 2D tape independent of the generic_advdiff ones,
916      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
917    
918    checkpoint62q (2010/12/29)
919    o model/src:
920      - check horizontal grid-spacing for unset or zero/negative values.
921      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
922    o pkg/flt:
923      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
924      - precision of input and output files set according to readBinaryPrec
925        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
926      - initial float position from tiled file was not converted to index space
927        (looks like a bug): fixed to make it similar to initial pos. global file.
928    o global_ocean.cs32x15:
929       change SIZE.h of AD set-up to get same tiling as with MPI.
930       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
931    o model/src:
932       add flag to control printing of domain fields (bathymetry, hFac ...) in
933       ini_mask_etc (call to plot_fieds_xy*).
934    o pkg/thsice:
935       if useEXF, some forcing fields are not valid in overlap: fixed by computing
936       over the interior only + apply EXCH at the end (like with SEAICE advection).
937    o pkg/mdsio:
938      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
939        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
940      - change barrier call for safe multi-threads access to 3-D shared buffer.
941      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
942      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
943        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
944    o pkg/flt:
945      - add fourth-order Runge-Kutta integration
946      - add basic exch2 support (only 1 facet supported so far!)
947    o pkg/mdsio+rw:
948      new S/R to read local (or tile independent) vector (read counterpart of
949       mds_writevec_loc, and front-end write_glvec_rl/rs).
950    o global_ocean.cs32x15: additional input_ad.seaice experiment
951        that uses pkg/seaice rather than pkg/thsice.
952        (using multidim advection for seaice)
953    o towards more F95 syntax for array specification in namelist:
954      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
955        of all verification experiments.
956           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
957          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
958      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
959    o global_ocean.cs32x15: additional input.seaice experiment
960        that uses pkg/seaice rather than pkg/thsice.
961    
962    checkpoint62p (2010/12/17)
963    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
964        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
965    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
966        allow for use of multim. advection in seaice adjoint.
967    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
968      - first attempt to close budgets by taking into account the freshwater
969        flux implied by the sublimation of snow and ice. So far only the
970        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
971        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
972    o eesupp/src:
973      new S/R with new option (NML_EXTENDED_F77) to change array specification
974      from F95 standard to commonly accepted extended F77 form.
975      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
976      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
977      for less tolerant f77 compiler (e.g., pgf77, g77).
978    o globalFiles:
979      commented out in parameter file "data" since it's not safe with MPI
980      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
981      in this case); no longer commented out in restart test (tst_2+2).
982    o add adTapeDir to specify a special directory where adjoint tapes are
983      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
984      and cannot be used together with mdsioLocalDir.
985    o nesting pkgs:
986      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
987      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
988      - add parameter files + utils dir + output from short run on beagle.
989    o pkg/seaice:
990        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
991    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
992      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
993    
994    checkpoint62o (2010/11/25)
995    o pkg/exf:
996      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
997    o pkg/seaice:
998      - seaice_ocean_stress: split a loop for better vectorization of the
999        adjoint code
1000      - seaice_growth.F: fix bug in conservation of freshwater connected to
1001        capping of heff, put contribution into d_HEFFbyNEG
1002      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
1003        by something more sensible (parameters that are what their name implies)
1004      - change some defaults, so that by default exf-parameters are used for
1005        things like rhoAir, cpAir,latent/sensible heat parameters, in order
1006        to reproduce the old results, many data.seaice now contain funny values
1007        for cpAir and latent heat of sublimation
1008    o packages_readparms.F: move exf_readparms up in line so that
1009        exf-parameters are visible for other packages (e.g. seaice)
1010    o debugMode & debugLevel=2:
1011      - differentiate between debugMode & debugLevel=2:
1012        debugMode: controls printing of debug messages (sequence of S/R calls).
1013        debugLevel: controls printing of algorithm intermediate results and stats.
1014      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
1015        => allows to print debug-stats without all sequence of call messages.
1016      - switch control of debug print from debugLevel to debugMode in many S/R.
1017    o pkg/obcs (obcs-sponge):
1018        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
1019        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
1020    o pkg/generic_advdiff:
1021      - record overlap minimum size for each advection scheme;
1022      - refine criteria on overlap minimum size;
1023      - check and stop (in gad_check) if overlap size is too small.
1024    o pkg/obcs:
1025      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
1026        once, in ptracers_implicit.F)
1027      - with seaice: remove test on empty file name in obcs_apply_seaice (always
1028        apply OB values when tile has OB)
1029    o model/src, coriolis setting:
1030      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
1031        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
1032        files (selectCoriMap=3) with any grid.
1033      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
1034    o pkg/seaice/seaice_growth.F:
1035        a few cosmetic changes that reduce the number of lines of code
1036    o pkg/obcs: add boundary conditions following Stevens (1990)
1037      - the code follows old MOM/NAOSIM code
1038      - so far it is only implemented for the eastern and western boundaries
1039        and NOT for pTracers
1040    o pkg/rbcs:
1041      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
1042        beginning of the first rbcs forcing period.
1043      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
1044        offline package, i.e., one file per time, labeled by iteration number;
1045        deltaTrbcs sets the timestep with which the data was generated;
1046        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
1047      - rbcsForcingCycle=0 makes forcing non-cyclic.
1048      - make arithmetic safe for negative times and odd forcing periods.
1049    
1050    checkpoint62n (2010/11/09)
1051    o pkg/seaice:
1052        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
1053    o pkg/obcs:
1054       New S/R to copy tracer value from the OB location to narrow band region
1055        (width = same as overlap) beyond the OB: preserve OB value (needed for
1056        high-order scheme) which were overwritten by EXCH call if in overlap
1057        region. Applied to theta, salt, ptracer and advected seaice variables.
1058       With seaice: use maskInC in similar way as in gad_advection.F,
1059        in seaice_advection.F and advect.F.
1060       Update output of experiment seaice_obcs and change exp4 to test OBCS with
1061        4th order Adv.Scheme. for pasive salt and ptracer.
1062    o tools/genmake2:
1063      - when looking for an optfile (not specified), only search for Fortran compiler
1064        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
1065      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
1066        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
1067      - set default for CPP to "cpp -traditional -P" (was the case without specifying
1068        an optfile, but otherwise default was just "cpp".
1069      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
1070      - when "CC" is not set in the optfile, look for possible C compiler
1071        (instead of just setting CC=cc)
1072      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
1073        => add a ".F" to ".o" rule for source files with no "#include" (such as
1074           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
1075      - move gfortran before g77 in list of possible Fortran compiler (consistent
1076        with reference compiler switch from g77 to gfortran)
1077    o pkg/seaice:
1078      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
1079        seaice_check that stops the model, when the CPP flag is used.
1080      o seaice_growth.F: make capping of ice volume conserving by returning the
1081        capped ice as freshwater to EmPmR. This does not change the verification
1082        experiments but will change runs where the capping is acutally active
1083    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
1084      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
1085         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
1086         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
1087    o tools/genmake2:
1088      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
1089      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
1090      - clean previous genmake log files before anything else.
1091      - change Makefile to remove testreport log files (*.tr_log) and genmake log
1092        files only with "CLEAN" target (instead of "Clean");
1093    o pkg/generic_advdiff:
1094      Change OBCS in multiDim advection (gad_advection.F):
1095       Use maskInC to prevent intermediate update of tracer-field in OB regions,
1096       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
1097       which were applying future time-step OB values.
1098      This way, all explicit calculations use current-time-step OB values
1099       (simpler and more consistent).
1100      Affects results when set-up uses time-varying OBC and multi-dim advection;
1101       update output of experiment seaice_obcs.
1102    o pkg/seaice:
1103      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
1104       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
1105         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
1106      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
1107       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
1108       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
1109    o pkg aim (2010/10/26):
1110      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
1111        formulation with obliquity, eccentricity, ... as run-time parameters,
1112      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
1113        upward shortwave radition at the surface (all-sky and clear-sky).
1114    o pkg/obcs:
1115      - writing sections with globalFiles=T does not work: switch to tiled-files
1116        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
1117      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
1118      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
1119    
1120    checkpoint62m (2010/10/21)
1121    o pkg/seaice: vectorize seaice_solve4temp.F
1122      - move iterations loops outside of i/j-loops
1123      - requires 2D arrays for TB and effConduct
1124      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
1125        modified in this routine
1126      - a little bit of clean up, adjusting indentation, etc.
1127      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
1128        performance and '**TWO' by '**2' (because TWO is a float),
1129        replaced ONE, ZERO
1130    o eesupp/src:
1131       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
1132    o pkg/seaice/seaice_growth.F
1133      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
1134      merging process. The merged routine has two branches, and one activates the 'evolution'
1135      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
1136      In summary, here is what the '10/10 revision' did consist of
1137        part 1: seaice_growth.F revisions 1.71 to 1.75
1138          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
1139            The emphasis here was on improving readability (e.g. by trying to use meaningful
1140            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
1141        part 1.5:
1142          - revising the lab_sea experiment to make it a more useful (i.e. stable
1143            and representative of an actual model run). This was done by generating a
1144            (winter) pickup to start from, switching back the main experiment dynamic
1145            solver from evp to lsr, having one of the experiments use the free drift solution.
1146        part 2: seaice_growth.F revisions 1.76 to 1.85
1147          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
1148          - Sorting out the various fields units and sign (set early on and reset at the end)
1149            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
1150            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
1151          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
1152            and simplifying logical expressions to further improve readibility.
1153        part 3: seaice_growth.F revisions 1.86 to 1.89
1154          - Re-organize the blocks of code more logically.
1155          - Merging the '_if.F' pieces that add something new.
1156    o pkg/thsice:
1157      - vectorize thsice_solve4temp and thsice_get_exf.
1158        Problem: thsice_solve4temp has an unvectorizable statement that
1159        might also be problematic for TAF
1160      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
1161        does not change the verifcation experiment, but will change all
1162        experiments that have this flag undefined (not tested in verification);
1163        a little reorganization to save a few 2D fields and recomputations
1164      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
1165      - 2nd step:  fix some store dirs
1166        o seems to work somewhat, i.e. using ifort but not g77
1167        o likely cause are incomplete init. or recomputation
1168        o start verification/global_ocean.cs32x15/input_ad.thsice
1169    o pkg/obcs: add support for exch2
1170      - the position of the boundary and prescribed values are specified using
1171        a global domain with exch2 facets stacked
1172        - in x for N,S boundaries (like W2_mapIO=-1)
1173        - in y for E,W boundaries (so E,W boundaries do not overlap)
1174    o pkg/mdsio: add support for writing global sections with exch2
1175        file layout is as for obcs described above:
1176        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
1177        - for y-z sections, facets are stacked in y
1178    o pkg/thsice:
1179       - change a few routines for better vectorization: thsice_albedo.F,
1180         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
1181         not affected, but in particular the latter routine has changed
1182         dramatically (not necessarily easier to read now).
1183       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
1184       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
1185    o verification/lab_sea:
1186      - overhaul of the forward model experiments. The main motivation
1187        for this revision is that lab_sea has proven quite fragile (when
1188        changing the sea-ice code, and switching platforms) to a point
1189        when failures were very hard to attribute to specific code problems.
1190      - the suspected reason for this fragility is noise amplification by evp so,
1191        to start with, we decided to replace evp with lsr in the main experiment.
1192      - the input.lsr experiment thus became obsolete and was removed.
1193      - it was replaced with the input.fd experiment that uses an
1194        analytical "free drift" solution as the ice velocity field.
1195      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
1196        will hopefully allow us to discriminate problems due to dynamic solvers
1197        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
1198        us to test additional options, along with the salt plume package.
1199      - Finally a pickup was generated (at the end of a one year run) to
1200        make the tests more representative of an actual model run. Previously
1201        the tests starting point was a 1m thickness of ice everywhere.
1202    o pkg/seaice:
1203      - introducing S\R seaice_freedrift.F that compute the
1204        analytical solution to an approximate ice momentum
1205        equation (i.e. the simple stress/coriolis balance).
1206      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
1207        of the free drift velocity field, and enable its use.
1208        To actually use the free drift solution as the model ice
1209        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
1210    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
1211    
1212    checkpoint62l (2010/10/04)
1213    o pkg/seaice:
1214      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
1215      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
1216       version (with USE_ORIGINAL_SBI undef);
1217    o add hooks for new packages OASIS, the package will follow
1218      (hooks exclude the seaice pkg for now)
1219    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
1220      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
1221      rather than mdsio_readvector.F/mdsio_writevector.F, within
1222      adread_adwrite.F to read/write adjoint-related tapes to disk.
1223    o eesupp and pkg/mdsio: ALLOW_WHIO
1224      Option to write/read 2D fields to files including tiles halos.
1225      The main purpose is for adjoint related "tape I/O".
1226      The secondary purpose is for debugging phases.
1227      A word on those rather specifically intended purposes.
1228      The code was meant to be stripped down to the bare minimum.
1229      Typically, there is a unique and basic mapping to the global
1230      buffer (tile by tile, then proc by proc, then level by level), and
1231      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
1232      meant to generate user friendly outputs of various shapes and forms.
1233      Rather it is intended, for the knowledgeabale developers,
1234      to be largely independent of the many mdsio options, to allow
1235      outputs of tiles+halos in debugging phases and in adjoint runs,
1236      and to allow some flexibility in tuning (adoint) I/O depending on each
1237      file system behavior. With regard to tuning, most of the potential knobs
1238      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
1239      to specify directories, to specify the typical size of I/O calls, etc.)
1240      are not yet included, and will be added if they prove useful.
1241    o pkg/seaice:
1242       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
1243    o pkg/seaice:
1244       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
1245       code (seaice_budget_ice_if.F) which enable to recover old standard
1246       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
1247       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
1248    o model/src (rStar):
1249       use simple average (not area weighted) of rStarFac at U,V point when using
1250       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
1251       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
1252    
1253    checkpoint62k (2010/09/17)
1254    o adjoint
1255       * changed verification/global_ocean.cs32x15 ; adjoint now tests
1256         Adams-Bashforth 3 + NLFS + RSTAR
1257       * some more modifs required for ECCO-GODAE v4
1258    o pkg/seaice
1259       add SEAICE_AGE_VOL option to use volume instead of area for
1260       integrating SEAICE_AGE
1261    o model/src:
1262     first check-in of sigma & hybrid-sigma coordinate code ; also includes     first check-in of sigma & hybrid-sigma coordinate code ; also includes
1263     non-linear free-surface parts ; but pressure-gradient not yet coded.     non-linear free-surface parts ; but pressure-gradient not yet coded.
