4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src/do_oceanic_phys.F:
8      - reset addMass to zero only if useICEFRONT ;
9      - separated k-loop for rhoInSitu calculation ;
10      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
11        and at constant T,S (= WdRHOdP);
12      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
13        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
14        transport of locally-referenced potential density);
15        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
16    o gluemnc:
17      - replace ncrcat with ncks when adding variables to *.glob.nc
18      - change the way variables without record dimensions are handled so that
19        files that have variables with and without record variables can be glued:
20        add a record dimension with a new unique name to be able to differentiate
21        between variable with and without a-prior record dimensions. Remove
22        this record dimension before adding the variable to the *.glob.nc file.
23        This procedure automatically works also for grid.*.nc files that do not
24        have any record dimension.
25    o verification/cpl_aim+ocn:
26      - generate new reference output on baudelaire (gfortran, mpich2) (previously
27        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
28    o pkg/obcs/obcs_calc_stevens.F:
29      - add code for northern and southern boundaries.
30      - reorder some loops to save some operations and so that drFBar can be scalar
31    o model/src:
32      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
33        truncation) and add diagnostics for Adams-Bashforth tendency increment.
34      - update test-exp. AD output:
35        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
36      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
37        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
38        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
39        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
40        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
41        tutorial_plume_on_slope.
42    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
43      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
44      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
45      does not even come with an F77 compiler anymore, this should not be
46      a limitation
47    
48    checkpoint63e (2011/11/06)
49    o pkg/seaice adjoint of LSR:
50      - substantially rework STORE dirs.
51      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
52        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
53        and only perform SOLV_MAX_FIXED adjoint iters.
54        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
55        always goes to same record, meaning that the last forward field will be
56        the one used in the adjoint - an approximation.
57      - now produces non-zero LSR-related gradients, and acceptable gradients for
58        An's zonal (x-z) test case (to be checked in)
59      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
60        (but these are screwed up by the thermodynamics in the first place);
61        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
62        output_adm.txt also reflects changes to seaice_lsr
63      - global_ocean.cs32x15:
64        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
65          (output_adm.seaice.txt was updated)
66        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
67          (output_adm.seaice_dynmix.txt)
68    o test-exp. exp4+stevens:
69      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
70    o pkg/seaice (lsr solver):
71      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
72        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
73      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
74      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
75        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
76      - compute (with new S/R) and print initial (+ free-driff sol. if available)
77        and final residual of linearised system.
78    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
79      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
80    o pkg/obcs: Stevens BCs (still only for east and west)
81      - fix Stevens BCs by using intermediate velocities of previous
82        time step as "baroclinic" contribution rather velocity of one grid cell
83        inside the boundaries; more consistent but makes the entire treatment
84        more complicated, requires new pickup files and two new S/Rs:
85        obcs_copy_uv_n and obcs_save_uv_n
86        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
87        (undefined by default)
88      - silently move computation of some grid factors into separate loops to
89        save some recomputations
90      - add a hack for non-linear free surface
91      - add a verification experiment to exp4 that tests this code
92    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
93    
94    checkpoint63d (2011/10/25)
95    o pkg/obcs + seaice-dynamics:
96      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
97        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
98        values (consistent with an implicit method).
99      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
100        return to older implementation (same results as before); note that none of
101        the "experimental" OBCS_SEAICE options are implemented in the new version.
102      - switch test exp. seaice_obcs to use new version (update output).
103    o pkg/seaice:
104      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
105      - add parenthesis in Water-Ice drag calculations (evp & lsr);
106      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
107        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
108      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
109        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
110    o pkg/layers:
111      - Include potential density as new coordinate (Thanks to David Munday)
112    o pkg/dic:
113      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
114        carbonate computation/output to CALC_PCO2_APPROX
115    o pkg/generic_advdiff
116      - make TAF generate code that vectorizes:
117        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
118    o model/src:
119      - improve vectorization also for adjoint code of
120        solve_tridiagonal and solve_pentadiagonal. As this requires up to
121        5 new 3D-fields, this code is only turned on for the combination of
122        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
123        for singular matrix check (only for TARGET_NEC_SX).
124      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
125        ALLOW_AUTODIFF. This flag now needs to be set outside of
126        solve_tri/pentadiagonal.F
127    o pkg/exf:
128      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
129        optional namelist EXF_NML_OBCS).
130      - add many debug-print (to trace down where pkg/cal error msg comes from)
131    o pkg/mom_vecinv/mom_vi_hdissip.F
132      - rearrange loops so that vectorization is improved and in particular
133        the adjoint routine vectorizes. The code is a little longer now, but I
134        think easier to read.
135        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
136    o pkg/seaice:
137      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
138    o pkg/exch2:
139      - alternative code (without tile x tile matrix) for cumulated (global) sum;
140        used as default; keep using matrix version in adjustment.cs-32x32x1.
141    o tools/build_options:
142      - after merging some MPI and/or multi-threads specific optfiles so that
143        the modified default optfile support both built (using genmake2 -mpi
144        for the MPI built, using genmake2 -omp for OpenMP built),
145        move now obsolete optfiles to tools/build_options/unsupported/
146       (add copy of email sent to support list in doc/optfiles_changes.txt)
147    
148    checkpoint63c (2011/09/28)
149    o pkg/ebm:
150      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
151        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
152    o pkg/seaice (SItracer pickup)
153    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
154      To be done:
155      - thorough testing of missing fields in S/R seaice_read_pickup
156      - thorough matching between generic tracers and specific fields used
157        (e.g. volume-weighted age, area-weighted age, salinity, ...)
158    o pkg/grdchk:
159      - all procs calculate and print finite-difference gradient (for testreport)
160      - change description output used by testreport;
161      - AD testing: also compare and report Finite-difference gradient;
162        => update all output_adm*.txt
163    o test exp. global_ocean_ebm:
164      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
165        and turn on exactConserve; update (fwd) output.
166    o pkg/seaice (LSR):
167      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
168      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
169        * identical results with non-CS topology (but save up to half of EXCH calls)
170        * no much changes in cs-32 verification tests since no ice at face edges
171         (differences due to convergence criteria, since nb of iterations changed)
172        * expect some differences on lat-lon-cap grid.
173        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
174    o pkg/exch2:
175      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
176        many tiles); until alternative coding is added, just add a stop.
177    o pkg/kpp:
178      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
179        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
180    o optfiles:
181      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
182        into corresponding standard one, which now support different build:
183        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
184      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
185    o pkg/obcs (seaice):
186      - add missing EXCH for uIce,vIce after applying OBCS;
187      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
188        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
189        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
190      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
191      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
192        and eedata.mth for MPI and mutlti-threaded testing.
193    o pkg/flt:
194      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
195      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
196      - fix pickup and trajectories + profiles output with multi-threads;
197      - add parameter to select group of fields to write along trajectory and
198        profile (default unchanged);
199      - only call PORT_RAND* function when flt_noise <> 0;
200      - add multi-threaded test for verification exp. flt_example.
201    o eesupp/src:
202      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
203      - USE_OMP_THREADING: check that number of threads (from eedata) matches
204        actual number (from env.var. setting).
205    o pkg/ebm:
206      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
207      - add multi-threaded test for verification exp. global_ocean_ebm
208    
209    checkpoint63b (2011/08/29)
210    o pkg/ebm:
211      - fix sign of runoff;
212      - update directly forcing fields (Qnet,EmPmR) to use standard
213        external_forcing_surf.F (remove ebm_forcing_surf.F);
214      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
215      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
216        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
217      - update global_ocean_ebm parameters file data and update output (fwd+ad).
218    o verification/matrix_example:
219      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
220        MPI and mutlti-threaded testing.
221    o pkg/matrix:
222      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
223      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
224      - fix for multi-threaded (remove DATA statement);
225      - use standard DIFFERENT_MULTIPLE function;
226      - add MATRIX_OPTIONS.h
227    o verification/matrix_example:
228       To allow to split the domain in several tiles, change the domain size
229        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
230        Western side) of land points.
231    o (*_)write_pickup:
232      - fix few bugs in mypackage_read/write_pickup.F
233      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
234        array of length 1 (was caught by compiler syntax-check).
235    o pkg/diagnostics (velocity potential solver):
236      - fix initialisation of main diagonal matrix (for overlap values)
237    o tools/build_options:
238      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
239        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
240      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
241        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
242        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
243        and use "-devel" testreport option for standard testing on baudelaire.
244    o pkg/grdchk:
245      - Assume that all gradient-check position are within the same tile
246        corresponding to global indices (iGloTile,jGloTile) and that
247        positions (i,j indices or nbeg) are local to this tile;
248      - set tile local-indices and proc. number according to tile global-indices;
249      - remove grdchkwhichproc from namelist (retired param);
250      - send adjoint gradient to all procs so that all procs print it to STDOUT;
251      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
252    o adding package bbl (Bottom Boundary Layer)
253      description in MITgcm/pkg/bbl/bbl_description.tex
254      example/test experiment in MITgcm_contrib/bbl
255    o adjoint verifications
256      - changed 5 experiments to multi-tiles
257        * global_ocean.90x40x15
258        * obcs_ctrl
259        * offline_exf_seaice
260        * tutorial_dic_adjoffline
261        * tutorial_tracer_adjsens
262        changed reference output for those that crossed tile boundaries
263        (changed choices of gradient check positions)
264      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
265      - temporary bug fix in grdchk_loc.F for obcs
266    o genmake2 & testreport
267      - add target "obj" (just for OBJFILES files) to Makefile;
268      - add option to specify FEXTRAFLAGS on command line.
269    o pkg/mypackage:
270      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
271    
272    checkpoint63a (2011/08/02)
273    o pkg/diagnostics (velocity potential):
274      - fix velocity-potential calculation when using OBCS: balance net inflow
275        at each level (new S/R OBCS_DIAG_BALANCE).
276      - fix some of the problems with OBCS in stream-function calculation.
277    o pkg/exf/exf_readparms.F
278      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
279        EXF_NML_OBCS) more consistent, so that you need not have these lists
280        in data.exf when they are not used.
281    o optim/optim_readdata.F:
282      - add some output about obcs variables that might help debugging
283      - add a check about nvarlength
284    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
285    o pkg/diagnostics (velocity potential):
286      - fix mask for OBCS (still problems in stream-function with OBCS);
287      - add specific parameter (default = main code CG2D params) for solver;
288      - in case of poor convergence, use solution corresponding to lowest residual.
289    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
290      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
291      and should be avoided where possible.
292    o model/src (rStar):
293      - include r* effect on reference-state (PhiRef) in totPhiHyd
294        (so that it's really the potential anomaly at the cell center);
295        affect solution only if z* with full pressure in EOS.
296      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
297        update output (because of z* in totPhiHyd and viscA4 changes);
298      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
299        @ constant r) until interpolation at constant r is implemented.
300    o pkg/diagnostics
301      - fix RCENTER diagnostics in case cell center is not at interface middle
302    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
303      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
304      that THETA and SALT are "conservative temperature" and "absolute
305      salinity"
306    o pkg/ctrl
307      - fix computation of endrec in s/r ctrl_init_rec
308      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
309    o pkg/seaice/seaice_growth.F
310      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
311        remove then obsolete STORE directives
312      - fix STORE directives for tice and tices, so that only the
313        appropriate part of the fields are stored (and not the entire
314        field); update global_ocean.cs32x15.seaice AD output.
315      - cosmetic changes: adjust CPP flags and indentation for better
316        legibilty
317    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
318      Chris Wilson)
319    o pkg/gmredi:
320       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
321       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
322    
323    checkpoint63  (2011/07/11)
324    o pkg/exch2:
325     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
326     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
327       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
328       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
329    o pkg/diagnostics:
330     - deal with pairs of post-processed diags which are computed together; in
331       particular, re-order list of diags within 1 file to save 2nd computation.
332     - add S/R to compute velocity stream-function (called after velocity-potential
333       calculation) from divergence free transport -> new diagnostics "PsiVEL".
334     - add parameter to select grid-point location where PsiVEL == 0.
335    o eesupp/src:
336       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
337       (specific S/R needed with exch2 topology - for now, just print an error msg)
338    o pkg/shelfice
339     - Implement friction velocity-dependent transfer coefficients following
340       Holland and Jenkins, JPO, 1999
341       Original code by M. Losch with small modifs.
342       Enable with CPP option SHI_ALLOW_GAMMAFRICT
343       and runtime flag SHELFICEuseGammaFrict
344    o verification lab_sea & global_ocean.cs32x15:
345     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
346       does not miss some dependencies (but is slower) and also works with many files
347       (default makedepend limitation for AD built).
348     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
349    o pkg/diagnostics:
350     - add run-time parameter "useMissingValue" (def=False) to fill land-point
351        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
352       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
353     - Extend the use of "missing_value" setting from data.diagnostics for the case
354       of counter-diagnostics (where fraction-weight is zero). This applies both to
355       MNC and MDS output files.
356    o pkg/seaice/seaice_growth.F:
357      - add 'a priori' cap of latent heat flux based on actual mass considerations
358        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
359        non-legacy seaice_solve4temp.
360      - add diagnostic of the residual sublimation freshwater flux (the freshwater
361        flux taken from the ocean if the total actual latent heat fluxes exceed
362        the maximum)
363      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
364       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
365      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
366       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
367      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
368      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
369    o verification 1D_ocean_ice_column:
370       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
371       update results
372    o pkg/diagnostics:
373     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
374       which are not filled-up but computed from other diags ; In this case, the mate
375       diag points to the primary (filled-up) diag to used for post processing.
376     - Update Velocity-potential computation using post-processed diag framework.
377     ==> Change the ordering of fields and time-periods in MDS output file
378       when using periodic averaging: now writes one time record with the full set
379       of fields for this time period, then the next time reccord (it used to be
380       one field with the full set of time records then the next field).
381         Note: this is now similar to NetCDF (MNC) output file. <==
382    
383    checkpoint62z (2011/06/21)
384    o adjoint monitor:
385     - Add adjoint monitor output for packages exf, seaice
386       and update relevant testreport output
387    o pkg/seaice:
388     - re-order diags inits so that they appear in order in available_diagnostics.log
389     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
390       area/heff/hsnow preceeding thermodynamic growth/melt.
391     - modified diag: SIdA; output actual effect, as the description states.
392     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
393     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
394       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
395        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
396     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
397     - added diagnostics for seaice generic tracers (SItr*).
398     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
399     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
400     I. Fenty: 18-Jun-2011:
401     Minor changes to seaice package:
402     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
403        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
404       - Differentiated "regularization variables" from "floor variables"
405        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
406        * hiceMin became SEAICE_hice_reg (old hiceMin)
407          (with _reg meaning regularization variable)
408       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
409        so as to ensure energy conservation when going between phases
410      - A22 was not used anywhere
411     2) Changed regularization procedure for heffActual and hsnowActual to ensure
412        well-boundedness and smooth adjoint in seaice_growth.F
413     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
414        because the old regularization always set heffActual >= 0.05 cm
415     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
416        on AREA when HEFF > 0.
417      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
418        requiring that DISABLE_AREA_FLOOR *not* be defined
419     Affected verifications:
420      - 1D_ocean_ice_column (output.txt output_adm.txt)
421      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
422    o pkg/diagnostics:
423      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
424      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
425        (was _RL, now integer) with option = 0 to retrieve all levels.
426      - add pieces of code to compute velocity potential at each level (new diagnostics
427        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
428        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
429      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
430        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
431        and in diagnostics_fract_fill.F (do not need a valid pointer for the
432        diagnostics counter-mate); check that definition of counter-diagnostic
433        includes a valid counter-mate (in diagnostics_set_levels.F).
434    o model/src (rStar):
435      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
436        affect solution only if z* with full pressure in EOS;
437        update output of test-exp global_ocean.90x40x15.
438    o pkg/seaice:
439      - introduce siEps=1e-5 parameter
440      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
441      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
442      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
443        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
444        as well as ice cover age and ridging index (attached to AREA).
445        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
446        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
447        Up to SItrMaxNum=3 tracers can be used simultaneously.
448    o pkg/salt_plume:
449      -introduce SPsalFRAC run time parameter that sets the fraction of the
450       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
451       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
452    o model debug options:
453      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
454        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
455      - Refine debug-msg printing selection (3 new levels):
456        debugMode  : controls printing of debug messages (sequence of S/R calls).
457        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
458         debLevZero =  0 ; /* level of disabled aux. msg printing */
459         debLevA =  1 ; /* level of minimum  aux. msg printing */
460         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
461         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
462         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
463         debLevE =  5 ; /* level of extensive debug printing */
464        New debugLevel default: with default debugMode value (=F),
465          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
466          and if debugMode=T, default debugLevel = 4 (debLevD).
467        Relation with previous settings:
468         debLevB (=2) corresponds to former debLevA (=1)
469         debLevD (=4) corresponds to former debLevB (=2)
470        Note:
471         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
472         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
473            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
474      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
475        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
476    o pkg/obcs:
477      - change OBCSfixTopo default from True to False (should not change the results);
478        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
479    o pkg/thsice:
480      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
481        2nd layer seaice sublimation (unlikely to happen)
482      - use Interior mask for OBCS in thsice_advection.F (similar to what is
483        done in gad_advection & seaice_advection).
484    o adjoint:
485      bug fix spotted by Gael Forget:
486      seaice_advection and thsice_advection still had
487      legacy CPP options to avoid CS corner updates for adjoint
488    o pkg/seaice:
489      => Change some of the defaults (2011/05/29):
490         - change SEAICEuseFluxForm default (from False to True)
491         - change DIFF1 default (from 0.004 m/s to 0. m/s)
492         And print warnings if DIFF1 is not set in data.seaice and centered
493          avection scheme is used without any diffusion.
494      also:
495      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
496      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
497      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
498        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
499        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
500      update results of test exp.:
501         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
502             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
503             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
504         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
505         seaice_obcs: output (SEAICEuseFluxForm=T)
506      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
507          for standard fwd & AD lab_sea tests (to keep the same output).
508    o pkg/seaice/seaice_growth.F:
509      - use Ian Fenty's capping formulas for actual ice
510      thickness thoughout EVOLUTION branch.
511      - put treatment pathological case #2) in CPP brackets
512      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
513      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
514    o pkg/seaice:
515      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
516      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
517      also pass fac as a param, which can be 1. (to update the tendency
518      field) or the time step (to update the field itself).
519      - seaice_advdiff.F: for multidim, call seaice_diffusion with
520      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
521      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
522      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
523      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
524    o pkg/seaice:
525      diffusion with centered advection scheme (diffus.F & advect.F):
526      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
527        to just compute the laplacian of input-field.
528      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
529      - fix flux-form version in diffus.F to conserve tracer.
530      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
531       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
532    
533    checkpoint62y (2011/05/26)
534    o pkg/seaice:
535     - seaice_growth.F : in EVOLUTION branch, always include
536       a_QSWbyATM_cover in qnet (as it should be).
537     - verification/global_ocean.cs32x15 : update results accordingly
538       (output.seaice.txt output_adm.seaice.txt).
539    o pkg/seaice + obcs:
540     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
541       equivalent of assuming no tracer gradient outside the OB region.
542       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
543     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
544       after changes above);
545     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
546       only at OB location (instead of over a band of OLx width).
547    o pkg/seaice:
548     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
549       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
550    o pkg/obcs:
551      - split header file "OBCS.h" into 4 separated files:
552        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
553       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
554         (contain no conditional statement which depends on OBCS options).
555      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
556        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
557    o ctrl, cost, grdchk & autodiff pkgs:
558      - make options file more standard (like other {PKG}_OPTIONS.h file but
559        with AD_CONFIG.h); clean-up some of the included header files.
560    o pkg/obcs:
561      - do not mask tracer when applying OB (tracer == 0 could generate problems)
562      - apply tracer OB values to tracer field only at OB location (instead of
563        over a band of OLx width)
564      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
565      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
566        obcs_apply_tloc.F & obcs_apply_sloc.F
567    o obcs in model/src:
568      - call OBCS_APPLY_W only if NonHydrostatic.
569      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
570      - reset dEtaHdt and wVel to zero outside OB interior region ;
571      - leave tracer unchanged outside OB interior region: This has no effect
572        on the solution but just to prevent unrealistic tracer value outside OB.
573      - zero out velocity outside OB interior region: This has no effect on
574        the solution but just to prevent unrealistic velocity outside OB.
575    o obcs and non-lin free-surf:
576       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
577       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
578       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
579       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
580       update results of test-exp. exp4(nlfs).
581    o exp4 (nlfs) test-exp:
582       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
583       with NonLin-FreeSurf); update output.nlfs.txt
584    o obcs and 2d/3d solver norm:
585       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
586       and outside OB interior region (will allow to place OB further inside the
587       domain). Depending on the domain, can affects cg2d-Norm (previous
588       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
589       and cg3d-Norm (previous Norm was computed before canceling OB terms),
590       e.g. in tutorial_plume_on_slope.
591      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
592    o pkg rbcs:
593      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
594      - add capability to apply relaxation to horizontal velocity uVel & vVel.
595    o pkg/grdchk: add gradient check for control variable xx_shifwflx
596    o pkg/shelfice/shelfice_init_fixed.F
597      fix CPP-flag combinations
598    o pkg/seaice: Merge iceage code of Pierre Rampal
599      * update/change/correct ice age calculations
600      * add age updates for pathological cases
601      Probably needs more testing...
602    
603    checkpoint62x (2011/05/13)
604    o pkg/mom_vecinv:
605       high-order vorticity scheme: use interior masks (maskInW & S)
606       to zero-out (outside OB) gradient of vorticity.
607    o verification exp.:
608       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
609       hs94.128x64x5 and seaice_obcs ; update results.
610    o pkg/obcs:
611      fix bug in OBeta for YZ sections in obcs_exf_load.F
612    o pkg/ctrl, pkg/shelfice, and optim:
613      - add new control variable xx_shifwflx (fresh water flux underneath ice
614        shelves). This is almost as tedious as obcs-ctrl, because the
615        variables needs its own mask.
616      - add a cost function term that penalizes the deviation of xx_shifwflx
617        from the first guess (zero) in analogy to other control variables
618    o pkg/shelfice:
619      - start basic adjoint
620    o pkg/ctrl:
621      - remove extra 2D field "for good measure" when initializing in
622        ctrl_set_globfld_[xy/xz/yz].F
623      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
624      - improve error messages in ctrl_set_unpack_*
625    o OBC implementation in momentum:
626       use interior masks (maskInC,W & S) in momentum S/R:
627       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
628       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
629       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
630       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
631       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
632        (and also with Leith/Smagorinsky harmonic-viscosity).
633       Update output of experiment dome and exp4 (+nlfs).
634    o exp4 test-exp:
635      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
636        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
637        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
638        time-varying OB at Western-side for wVel (NonHyd); update output.
639      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
640        and biharmonic-viscosity ; also use prescribed time varying OB.
641    o pkg/obcs:
642      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
643    o model/src:
644      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
645      - initialise startTime & nIter0 with unlikely values: allows to set one
646        from the other without ambiguity.
647    o seaice_obcs test-exp.:
648      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
649    o pkg/obcs:
650      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
651        no longer needed with maskInC,W,S in pkg/generic_advdiff.
652    o pkg/seaice:
653      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
654        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
655      - fixed bug in the initialization of sea ice salinity variable HSALT
656        in seaice_init_varia.F  (removed dependence on ICE2WATR)
657    o fizhi-cs test exp.:
658       switch reference output convention for these 2 non-standard test-exp,
659        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
660          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
661       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
662    o model/inc:
663      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
664        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
665    o pkg/seaice:
666      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
667    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
668      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
669        and initial HSALT
670    
671    checkpoint62w (2011/04/26)
672    o pkg/mom_fluxform:
673      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
674      - use parameter "sideDragFactor" in no-slip BC side-drag part.
675      - update output of exp. global_ocean.90x40x15
676    o pkg/mom_vecinv:
677      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
678    o update seaice exp.:
679      use more consistent parameter values (remove "backward compatability only":
680       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
681      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
682       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
683    o update test-exp global_ocean.90x40x15:
684      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
685      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
686      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
687      o turn on zStar & viscA4 in standard set-up (dir input/)
688        and update output files: output.txt & output.dwnslp.txt
689    o new AD-test experiment: obcs_ctrl
690      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
691    o pkg/dic:
692      fix two bugs in handling water vapour pressure in carbonate chemistry
693      and air-sea fluxes. Found by Val Bennington and Galen McKinley
694      (add DIC Option = WATERVAP_BUG to recover old results)
695      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
696    o adding allowInteriorFreezing option to check for water below freezing point
697      at depth and bring the negative heat anomaly to the surface level
698    o pkgs _fields_load:
699      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
700      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
701        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
702        rbcs to get interpolation weights and time reccord number.
703      - fix multi-threading in aim_fields_load.F
704      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
705    o external_fields_load:
706      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
707       interpolation weights) to use in a periodic time-series ; do not divide by
708       time-step to convert to integer:
709       - this fixes case where externForcingPeriod is not multiple of time-step
710          (Thanks to Christopher L. Wolfe)
711       - this fixes case where externForcingPeriod is an odd multiple of time-step
712         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
713      store index of time-record which is currently loaded:
714       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
715       - needed for the adjoint but not yet used because of extensive recomputations;
716         (to be fixed soon)
717    
718    checkpoint62v (2011/04/02)
719    o verification/1D_ocean_ice_column added to test Ian Fenty's
720      pkg/seaice_growth.F modifications for improving sea ice code differentiability
721    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
722      (new velocity statistics after changing maskInW & maskInS definition)
723    o pkg/generic_advdiff with OBCS:
724      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
725      equivalent to assumption of no tracer gradient outside the OB region.
726      This will affect the results if using obcs+biharmonic diffusion.
727      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
728    o pkg/obcs:
729      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
730      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
731      in Interior region. No impact on solution but affects Velocity monitor stats.
732    o pkg/ptracers (adjoint)
733      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
734      tape file for each tracer
735    o model/inc/src and pkg/autodiff: add parameters that allow to turn
736      of parts of the adjoint code at run time. For now, there are only
737      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
738      parameters are set in data.pkg.
739      This is the lazy coward's version of doing this, but still useful for
740      debugging. In order to do it right, everything needs to be moved to
741      pkg/autodiff.
742    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
743      the end; this fixes the adjoint balancing code for open boundaries.
744    o pkg/ctrl:
745      - change behavior of xx_${varname}period to be analogous to exf-conventions:
746        xx_${varname}period =   0.,  means time-independent control part
747        xx_${varname}period = -12., means one-year-periodic monthly control part
748      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
749        clean up ctrl_init a little, remove unused variables
750      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
751      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
752    
753    checkpoint62u (2011/03/15)
754    o model/src:
755      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
756        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
757      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
758        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
759    o pkg/ctrl/obcs/ecco:
760      - remove obsolete, unused, and partially broken code:
761        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
762        ALLOW_CTRL_OBCS_BALANCE
763      - put a stop statement into ecco/cost_obcsvol.F, but also add
764        cost_obcsvol to ecco_ad_diff.list
765    o pkg/ecco: fix counting cost function contributions for obcs (code
766      by Matt M.) and diffkr for diagnostics
767    o pkg/ecco, pkg/ctrl, pkg/grdchk:
768      add cost penalty terms for initial uvel, vvel, eta controls
769      and I/O for prior error files
770    o pkg/mdsio:
771       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
772       (new argument) to check for tiled file in mdsioLocalDir : this fix the
773       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
774    o pkg/ctrl:
775     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
776       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
777       unused and superfluous variables
778     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
779    o pkg/ecco
780     - enable adjoint of Stevens OB
781    o pkg/ctrl/ecco/grdchk:
782      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
783        Fortunately, we do not have any tests for the numerous cpp-flagged
784        option of "obcs as control parameters" so we will never know
785        if this is an improvement (but at least now things compile).
786      - remove an obsolete initialization from ecco_cost_init_barfiles.F
787      - fix some problems within never used ifdefs to make the code compile
788    o pkg/obcs:
789     - Refine Interior mask definition to work with more complex OB (e.g.
790       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
791       read in Interior mask from file. Check if Interior mask is consistent
792       with OB list of indices.
793    o pkg/seaice
794     - beginning code for a seaice tracer package,
795       but currently only used for seaice age: SEAICE_AGE
796       SEAICE_num = 4
797       iTracer = 1: area-weighted ice age
798               = 2: volume-weighted ice age
799               = 3, 4: template for one-year vs. multi-year ice
800       data.seaice has new namelist SEAICE_PARM03 for arrays related to
801       SEAICE_num
802    
803    checkpoint62t (2011/03/05)
804    o pkg/obcs:
805     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
806       then normal component. This ensures that the normal component is set
807       correctly even when it conficts with tangential setting from an other OB.
808       Affects results of test-experiment seaice_obcs: update the output.txt
809    o pkg/obcs:
810     - add code to monitor statistics of dynamical fields at OB.
811     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
812       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
813       - change default: balance the Net inflow through all OB (instead of balancing
814         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
815     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
816       to match Nortern OB inflow (OBCS_balanceFacN=0).
817    o pkg/seaice:
818     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
819    o pkg/seaice (seaice_growth v 1.113):
820     - reverting seaice_growth to v 1.111 in order to have code with exact bit
821       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
822       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
823       runtime flag SEAICEareaFormula is kept but is inactive
824    o model/src:
825     - add new param to scale curvilinear grid distance and area when using
826       a different sphere radius from the grid-files.
827     - test/check multi-threads EXCH applied to local variable (cg2d_x)
828    o adjoint:
829     - enable adjoint of Stevens OB
830     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
831       (a bit delicate because of potentially modified adj. common block structure;
832       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
833    
834    checkpoint62s (2011/02/15)
835    o pkg/seaice (seaice_growth v 1.112):
836     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
837       computing the ice cover tendency from effective thickness tendencies. Include
838       Ian Fenty's formula.
839     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
840       SEAICEareaFormula.
841     - simplify notations for the various d_HEFF/d_AREA terms.
842    o pkg/gmredi:
843     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
844       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
845       add a verification test-run (front_relax.bvp) to test GM_useBVP.
846    o pkg/seaice (seaice_growth v 1.111):
847     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
848     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
849       also melt ice.
850    o pkg/seaice:
851     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
852     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
853    o pkg/cheapaml:
854     - from Nico Wienders: New version of this package.
855    o pkg/flt:
856     - add CPP options to prevent floats to re-enter the opposite side of
857       a periodic domain (default: keep periodicity)
858    o pkg/gmredi:
859     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
860       (needed for multi-dim advection).
861     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
862    o model/src:
863     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
864    o tutorial_tracer_adjsens
865     - extend to NLFS and replace maskC by hFacC
866       (change reference output accordingly)
867    
868    checkpoint62r (2011/01/24)
869    o testreport:
870     - add option -deloutp (-do) to remove output file after successful run
871     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
872       extract exact list of procs from this file ; adjust COMMAND by
873       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
874    o pkg/ecco: replace old ineffective way of penalizing deviations from
875      first guess (of obcs) with code by Matt Mazloff
876    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
877      exf/cal
878      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
879        and handle case of obcs?period == 0
880        Not affected by these changes: There is still an inconsistency in
881        the computation of start/endrec for the obcs variables for ALLOW_CAL
882        defined (see comment by Menemenlis, 7-Mar-2003)
883      - make S/R ctrl_get_gen_rec return something meaningful even if
884        ALLOW_CAL is not defined
885      - ctrl_getobcs?: simplify code so that it does not need to use
886                       S/R exf_swapfields
887    o testreport:
888       allow to test MPI with different number of processors for each experiment:
889       create file "SIZE.h.mpi" in each build dir.
890       Note: update of "-command" argument not yet implemented.
891    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
892      alleviate the need for additional 3D tapes when using
893      the non-inear free surface in the adjoint. This is done
894      by adding an 'update' of hfacc etc. to their current
895      value at the beginning of forward_step.F.
896    o pkg/seaice
897      seaice_lsr: move stress-divergence computations out of outer pseudo-
898      timestepping loop
899    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
900      up, so that the calls of the ctrl_* subroutines are really at the end
901      of the routine.
902    o pkg/gmredi:
903      allow to specify a 2-D horizontal map and a 1-D vertical profil
904      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
905    o pkg/seaice:
906      move lsr iterations from seaice_dynsolver to seaice_lsr.
907    o pkg/seaice:
908      reduce memory footprint of seaice mutldim advection tapes,
909      by using a 2D tape independent of the generic_advdiff ones,
910      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
911    
912    checkpoint62q (2010/12/29)
913    o model/src:
914      - check horizontal grid-spacing for unset or zero/negative values.
915      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
916    o pkg/flt:
917      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
918      - precision of input and output files set according to readBinaryPrec
919        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
920      - initial float position from tiled file was not converted to index space
921        (looks like a bug): fixed to make it similar to initial pos. global file.
922    o global_ocean.cs32x15:
923       change SIZE.h of AD set-up to get same tiling as with MPI.
924       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
925    o model/src:
926       add flag to control printing of domain fields (bathymetry, hFac ...) in
927       ini_mask_etc (call to plot_fieds_xy*).
928    o pkg/thsice:
929       if useEXF, some forcing fields are not valid in overlap: fixed by computing
930       over the interior only + apply EXCH at the end (like with SEAICE advection).
931    o pkg/mdsio:
932      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
933        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
934      - change barrier call for safe multi-threads access to 3-D shared buffer.
935      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
936      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
937        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
938    o pkg/flt:
939      - add fourth-order Runge-Kutta integration
940      - add basic exch2 support (only 1 facet supported so far!)
941    o pkg/mdsio+rw:
942      new S/R to read local (or tile independent) vector (read counterpart of
943       mds_writevec_loc, and front-end write_glvec_rl/rs).
944    o global_ocean.cs32x15: additional input_ad.seaice experiment
945        that uses pkg/seaice rather than pkg/thsice.
946        (using multidim advection for seaice)
947    o towards more F95 syntax for array specification in namelist:
948      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
949        of all verification experiments.
950           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
951          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
952      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
953    o global_ocean.cs32x15: additional input.seaice experiment
954        that uses pkg/seaice rather than pkg/thsice.
955    
956    checkpoint62p (2010/12/17)
957    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
958        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
959    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
960        allow for use of multim. advection in seaice adjoint.
961    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
962      - first attempt to close budgets by taking into account the freshwater
963        flux implied by the sublimation of snow and ice. So far only the
964        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
965        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
966    o eesupp/src:
967      new S/R with new option (NML_EXTENDED_F77) to change array specification
968      from F95 standard to commonly accepted extended F77 form.
969      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
970      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
971      for less tolerant f77 compiler (e.g., pgf77, g77).
972    o globalFiles:
973      commented out in parameter file "data" since it's not safe with MPI
974      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
975      in this case); no longer commented out in restart test (tst_2+2).
976    o add adTapeDir to specify a special directory where adjoint tapes are
977      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
978      and cannot be used together with mdsioLocalDir.
979    o nesting pkgs:
980      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
981      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
982      - add parameter files + utils dir + output from short run on beagle.
983    o pkg/seaice:
984        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
985    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
986      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
987    
988    checkpoint62o (2010/11/25)
989    o pkg/exf:
990      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
991    o pkg/seaice:
992      - seaice_ocean_stress: split a loop for better vectorization of the
993        adjoint code
994      - seaice_growth.F: fix bug in conservation of freshwater connected to
995        capping of heff, put contribution into d_HEFFbyNEG
996      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
997        by something more sensible (parameters that are what their name implies)
998      - change some defaults, so that by default exf-parameters are used for
999        things like rhoAir, cpAir,latent/sensible heat parameters, in order
1000        to reproduce the old results, many data.seaice now contain funny values
1001        for cpAir and latent heat of sublimation
1002    o packages_readparms.F: move exf_readparms up in line so that
1003        exf-parameters are visible for other packages (e.g. seaice)
1004    o debugMode & debugLevel=2:
1005      - differentiate between debugMode & debugLevel=2:
1006        debugMode: controls printing of debug messages (sequence of S/R calls).
1007        debugLevel: controls printing of algorithm intermediate results and stats.
1008      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
1009        => allows to print debug-stats without all sequence of call messages.
1010      - switch control of debug print from debugLevel to debugMode in many S/R.
1011    o pkg/obcs (obcs-sponge):
1012        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
1013        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
1014    o pkg/generic_advdiff:
1015      - record overlap minimum size for each advection scheme;
1016      - refine criteria on overlap minimum size;
1017      - check and stop (in gad_check) if overlap size is too small.
1018    o pkg/obcs:
1019      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
1020        once, in ptracers_implicit.F)
1021      - with seaice: remove test on empty file name in obcs_apply_seaice (always
1022        apply OB values when tile has OB)
1023    o model/src, coriolis setting:
1024      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
1025        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
1026        files (selectCoriMap=3) with any grid.
1027      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
1028    o pkg/seaice/seaice_growth.F:
1029        a few cosmetic changes that reduce the number of lines of code
1030    o pkg/obcs: add boundary conditions following Stevens (1990)
1031      - the code follows old MOM/NAOSIM code
1032      - so far it is only implemented for the eastern and western boundaries
1033        and NOT for pTracers
1034    o pkg/rbcs:
1035      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
1036        beginning of the first rbcs forcing period.
1037      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
1038        offline package, i.e., one file per time, labeled by iteration number;
1039        deltaTrbcs sets the timestep with which the data was generated;
1040        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
1041      - rbcsForcingCycle=0 makes forcing non-cyclic.
1042      - make arithmetic safe for negative times and odd forcing periods.
1043    
1044    checkpoint62n (2010/11/09)
1045    o pkg/seaice:
1046        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
1047    o pkg/obcs:
1048       New S/R to copy tracer value from the OB location to narrow band region
1049        (width = same as overlap) beyond the OB: preserve OB value (needed for
1050        high-order scheme) which were overwritten by EXCH call if in overlap
1051        region. Applied to theta, salt, ptracer and advected seaice variables.
1052       With seaice: use maskInC in similar way as in gad_advection.F,
1053        in seaice_advection.F and advect.F.
1054       Update output of experiment seaice_obcs and change exp4 to test OBCS with
1055        4th order Adv.Scheme. for pasive salt and ptracer.
1056    o tools/genmake2:
1057      - when looking for an optfile (not specified), only search for Fortran compiler
1058        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
1059      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
1060        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
1061      - set default for CPP to "cpp -traditional -P" (was the case without specifying
1062        an optfile, but otherwise default was just "cpp".
1063      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
1064      - when "CC" is not set in the optfile, look for possible C compiler
1065        (instead of just setting CC=cc)
1066      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
1067        => add a ".F" to ".o" rule for source files with no "#include" (such as
1068           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
1069      - move gfortran before g77 in list of possible Fortran compiler (consistent
1070        with reference compiler switch from g77 to gfortran)
1071    o pkg/seaice:
1072      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
1073        seaice_check that stops the model, when the CPP flag is used.
1074      o seaice_growth.F: make capping of ice volume conserving by returning the
1075        capped ice as freshwater to EmPmR. This does not change the verification
1076        experiments but will change runs where the capping is acutally active
1077    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
1078      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
1079         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
1080         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
1081    o tools/genmake2:
1082      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
1083      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
1084      - clean previous genmake log files before anything else.
1085      - change Makefile to remove testreport log files (*.tr_log) and genmake log
1086        files only with "CLEAN" target (instead of "Clean");
1087    o pkg/generic_advdiff:
1088      Change OBCS in multiDim advection (gad_advection.F):
1089       Use maskInC to prevent intermediate update of tracer-field in OB regions,
1090       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
1091       which were applying future time-step OB values.
1092      This way, all explicit calculations use current-time-step OB values
1093       (simpler and more consistent).
1094      Affects results when set-up uses time-varying OBC and multi-dim advection;
1095       update output of experiment seaice_obcs.
1096    o pkg/seaice:
1097      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
1098       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
1099         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
1100      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
1101       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
1102       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
1103    o pkg aim (2010/10/26):
1104      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
1105        formulation with obliquity, eccentricity, ... as run-time parameters,
1106      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
1107        upward shortwave radition at the surface (all-sky and clear-sky).
1108    o pkg/obcs:
1109      - writing sections with globalFiles=T does not work: switch to tiled-files
1110        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
1111      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
1112      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
1113    
1114    checkpoint62m (2010/10/21)
1115    o pkg/seaice: vectorize seaice_solve4temp.F
1116      - move iterations loops outside of i/j-loops
1117      - requires 2D arrays for TB and effConduct
1118      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
1119        modified in this routine
1120      - a little bit of clean up, adjusting indentation, etc.
1121      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
1122        performance and '**TWO' by '**2' (because TWO is a float),
1123        replaced ONE, ZERO
1124    o eesupp/src:
1125       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
1126    o pkg/seaice/seaice_growth.F
1127      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
1128      merging process. The merged routine has two branches, and one activates the 'evolution'
1129      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
1130      In summary, here is what the '10/10 revision' did consist of
1131        part 1: seaice_growth.F revisions 1.71 to 1.75
1132          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
1133            The emphasis here was on improving readability (e.g. by trying to use meaningful
1134            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
1135        part 1.5:
1136          - revising the lab_sea experiment to make it a more useful (i.e. stable
1137            and representative of an actual model run). This was done by generating a
1138            (winter) pickup to start from, switching back the main experiment dynamic
1139            solver from evp to lsr, having one of the experiments use the free drift solution.
1140        part 2: seaice_growth.F revisions 1.76 to 1.85
1141          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
1142          - Sorting out the various fields units and sign (set early on and reset at the end)
1143            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
1144            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
1145          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
1146            and simplifying logical expressions to further improve readibility.
1147        part 3: seaice_growth.F revisions 1.86 to 1.89
1148          - Re-organize the blocks of code more logically.
1149          - Merging the '_if.F' pieces that add something new.
1150    o pkg/thsice:
1151      - vectorize thsice_solve4temp and thsice_get_exf.
1152        Problem: thsice_solve4temp has an unvectorizable statement that
1153        might also be problematic for TAF
1154      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
1155        does not change the verifcation experiment, but will change all
1156        experiments that have this flag undefined (not tested in verification);
1157        a little reorganization to save a few 2D fields and recomputations
1158      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
1159      - 2nd step:  fix some store dirs
1160        o seems to work somewhat, i.e. using ifort but not g77
1161        o likely cause are incomplete init. or recomputation
1162        o start verification/global_ocean.cs32x15/input_ad.thsice
1163    o pkg/obcs: add support for exch2
1164      - the position of the boundary and prescribed values are specified using
1165        a global domain with exch2 facets stacked
1166        - in x for N,S boundaries (like W2_mapIO=-1)
1167        - in y for E,W boundaries (so E,W boundaries do not overlap)
1168    o pkg/mdsio: add support for writing global sections with exch2
1169        file layout is as for obcs described above:
1170        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
1171        - for y-z sections, facets are stacked in y
1172    o pkg/thsice:
1173       - change a few routines for better vectorization: thsice_albedo.F,
1174         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
1175         not affected, but in particular the latter routine has changed
1176         dramatically (not necessarily easier to read now).
1177       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
1178       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
1179    o verification/lab_sea:
1180      - overhaul of the forward model experiments. The main motivation
1181        for this revision is that lab_sea has proven quite fragile (when
1182        changing the sea-ice code, and switching platforms) to a point
1183        when failures were very hard to attribute to specific code problems.
1184      - the suspected reason for this fragility is noise amplification by evp so,
1185        to start with, we decided to replace evp with lsr in the main experiment.
1186      - the input.lsr experiment thus became obsolete and was removed.
1187      - it was replaced with the input.fd experiment that uses an
1188        analytical "free drift" solution as the ice velocity field.
1189      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
1190        will hopefully allow us to discriminate problems due to dynamic solvers
1191        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
1192        us to test additional options, along with the salt plume package.
1193      - Finally a pickup was generated (at the end of a one year run) to
1194        make the tests more representative of an actual model run. Previously
1195        the tests starting point was a 1m thickness of ice everywhere.
1196    o pkg/seaice:
1197      - introducing S\R seaice_freedrift.F that compute the
1198        analytical solution to an approximate ice momentum
1199        equation (i.e. the simple stress/coriolis balance).
1200      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
1201        of the free drift velocity field, and enable its use.
1202        To actually use the free drift solution as the model ice
1203        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
1204    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
1205    
1206    checkpoint62l (2010/10/04)
1207    o pkg/seaice:
1208      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
1209      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
1210       version (with USE_ORIGINAL_SBI undef);
1211    o add hooks for new packages OASIS, the package will follow
1212      (hooks exclude the seaice pkg for now)
1213    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
1214      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
1215      rather than mdsio_readvector.F/mdsio_writevector.F, within
1216      adread_adwrite.F to read/write adjoint-related tapes to disk.
1217    o eesupp and pkg/mdsio: ALLOW_WHIO
1218      Option to write/read 2D fields to files including tiles halos.
1219      The main purpose is for adjoint related "tape I/O".
1220      The secondary purpose is for debugging phases.
1221      A word on those rather specifically intended purposes.
1222      The code was meant to be stripped down to the bare minimum.
1223      Typically, there is a unique and basic mapping to the global
1224      buffer (tile by tile, then proc by proc, then level by level), and
1225      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
1226      meant to generate user friendly outputs of various shapes and forms.
1227      Rather it is intended, for the knowledgeabale developers,
1228      to be largely independent of the many mdsio options, to allow
1229      outputs of tiles+halos in debugging phases and in adjoint runs,
1230      and to allow some flexibility in tuning (adoint) I/O depending on each
1231      file system behavior. With regard to tuning, most of the potential knobs
1232      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
1233      to specify directories, to specify the typical size of I/O calls, etc.)
1234      are not yet included, and will be added if they prove useful.
1235    o pkg/seaice:
1236       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
1237    o pkg/seaice:
1238       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
1239       code (seaice_budget_ice_if.F) which enable to recover old standard
1240       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
1241       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
1242    o model/src (rStar):
1243       use simple average (not area weighted) of rStarFac at U,V point when using
1244       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
1245       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
1246    
1247    checkpoint62k (2010/09/17)
1248    o adjoint
1249       * changed verification/global_ocean.cs32x15 ; adjoint now tests
1250         Adams-Bashforth 3 + NLFS + RSTAR
1251       * some more modifs required for ECCO-GODAE v4
1252    o pkg/seaice
1253       add SEAICE_AGE_VOL option to use volume instead of area for
1254       integrating SEAICE_AGE
1255    o model/src:
1256       first check-in of sigma & hybrid-sigma coordinate code ; also includes
1257       non-linear free-surface parts ; but pressure-gradient not yet coded.
1258    o pkg/ptracers:
1259       option for ptracer to convert Salt Relax into additional EmP.
1260        tested in exp. global_ocean.90x40x15.dwnslp (update output)
1261    
1262    checkpoint62j (2010/08/25)
1263    o pkg/ggl90:
1264       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
1265    o pkg/dic: car_flux.F, phos_flux.F
1266      - reduce number of exp-calls in order to improve performance
1267      - clean up a little (replace fields by their macros, etc., fix
1268        typo in CPP-flag)
1269    o pkg/ggl90: minor changes
1270      - GGL90diffKrS was removed --> always use GGL90diffKr
1271      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
1272      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
1273        (commented out for now)
1274      - change in max/min operations to ensure that smoothing is ok
1275      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
1276      - always use diffKrNrT as background profile (i.e. never use diffKr field)
1277    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
1278    o pkg/dic:
1279      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
1280        vectorization
1281      - small bug fix in insol for the unlikely case of a cartesian grid
1282      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
1283        + now vectorize, which also removes adjoint recomputations;
1284        + replace integer maksp1 by _RL maskp1
1285        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
1286    
1287    checkpoint62i (2010/07/21)
1288    o pkg/flt:
1289      - with OBCS: stop floats which enter the OB region
1290    o model/src:
1291      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
1292        for implicit vertical advection.
1293    o pkg/seaice:
1294     - account for melting in seaice age evolution.
1295     - remove double counting of seaice ridging effect on seaice age.
