5      ==============================      ==============================
6    
7    o verification: to get more experiments tested with mpi, mth and mpi+mth,
8      change tiling of:
9       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
10       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
11      update output of exp:
12       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
13       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
14      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
15                       (note: output.txt generated on faulks using only 1 tile)
16    o eesupp & mdsio (SingleCpuIO):
17     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
18       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
19       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
20     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
21     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
22       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
23    o pkg/exch2:
24     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
25       read parameter file "data.exch2" if it exists; otherwise try default regular
26       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
27     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
28       with new code (not to be used, just as a backup solution).
29     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
30       in utils/exch2/input.
31    
32    checkpoint61n
33    o eesupp & mdsio (SingleCpuIO):
34      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
35        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
36        receive real*4 array (instead of real*8) to read/write 32.bit files.
37        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
38         and remove new mapping S/R)
39    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
40      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
41        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
42        when using exch2. Add S/R to map global io-buffer to global model array.
43      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
44    
45    checkpoint61m
46    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
47      and add 3 other S/R for other types (R4,R8,RS).
48      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
49    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
50     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
51     - reduce number of macro definitions (keep only those which are used);
52       can always call directly the corrresponding S/R if needed.
53     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
54       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
55     Fixed wrong type of arg in:
56       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
57       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
58     To fix: global_sum of var in common block is wrong (multi-threaded) in:
59       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
60     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
61    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
62      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
63    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
64    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
65      edges are closed (zero depth); might happen with "blank tiles";
66      for now, disabled if using OBCS.
67    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
68      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
69    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
70      to reduce length of 1.D array print in STDOUT.
71    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
72      + use 48 tiles (16x8): this will allow to test "blank tiles".
73    o start to test MPI + multi-threaded (change testreport to skip tests
74      where number of tiles do not match).
75    o genmake2: add option "-omp" to turn on Open-MP ;
76      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
77    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
78      and keep the original tile numbering. Note: compatible with old
79      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
80    
81    checkpoint61l
82    o Overlaps had been forgotten in calculating ijk keys : fixed
83    o fix cyrus makedepend for gcc 4.4
84    o experiment fizhi-cs-aqualev20:
85      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
86      and generate new output. Note: new output is much closer to the old
87      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
88      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
89    o pkg/fizhi:
90     - change to avoid indices going deliberately over array-bounds
91     - remove unnecessary MPI stuff
92     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
93     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
94       does not go over array-bounds and therefore returns reliable output.
95     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
96       this S/R has 4 output arguments, which are used inside "get_alarm";
97       when it is called with the same variable "ndum" in place of several
98       output arguments, this produces weird side effect inside "get_alarm"
99      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
100       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
101       address) and produces error.
102    o tools/gemake2: (March 27-29 2009)
103      with option "-mpi": link *_mpi files from "MODS" dir (this is what
104      testreport does).
105    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
106    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
107       update lab_sea.lsr & lab_sea.salt_plume results
108    o pkg/seaice:
109      Major overhaul of the LSOR solver: change discretization from original
110      finite differences to finite volume. The old routine is still in the
111      file seaice_lsr.F and can be turned on with the CPP-flag
112      SEAICE_OLD_AND_BAD_DISCRETIZATION
113      Along with this change, the discretization of the strain rates is changed.
114      The same flag turns on the old discretization in seaice_calc_strainrates.F
115      All verification experiments with seaice are affected (except for
116      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
117      results by setting the above flag.
118      Further changes involve changes in defaults:
119      - ALLOW_FLOODING is defined and turned on by default
120      - SEAICEadvSnow = .true. is now the default
121      - SEAICEadvSalt = .true. is now the default
122      - SEAICEadvAge  = .true. is now the default
123      - SEAICE_clipVelocities  = .false. is now the default
124                                         (as per J. Zhang's recommendation)
125      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
126        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
127      - seaice_growth: replace computation of UG by a simple copy from wspeed
128    
129    checkpoint61k
130    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
131      seaice_lsr: fixed a few metric terms,
132                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
133                  add more debugging diagnostics
134      seaice_evp: removed superfluous many metric terms of FV discretization
135                  of stress divergence
136                  affects lab_sea, lab_sea.hb87
137      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
138                  of stress divergence for non-evp solver
139                  (this part is not tested anywhere)
140      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
141                  they were effectively only half slip
142                  affects lab_sea.hb87
143      updated all relevant verification experiments (except lab_sea//output_adm.txt
144        which was left over, but fails at level 7 & 6)
145    
146    checkpoint61j
147    o pkg/seaice: turn a few hard wired parameters into run time parameters
148    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
149      time in seconds as promised by the usints in seaice_monitor and exf_monitor
150    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
151      that are not cubed-sphere grids
152    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
153    o pkg/ctrl:
154      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
155    o non-hydrostatic (calc_gw.F):
156      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
157      update output of exp. global_ocean.cs32x15.viscA4
158    o remove backward compatibility for thetaMin,phiMin
159      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
160    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
161      interpolated wind field not only for curvilineargrid=.true., but also
162      for a rotated grid (rotateGrid=.true.)
163    o pkg/exf: add capability to bypass interpolation for runoff
164      by setting yet another CPP-flag
165    o eesupp/src, B-grid exchange:
166      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
167    o autodiff
168      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
169      allows to switch to single-prec common blocks;
170      corresponding switch occurs in tamc.h, integer isbyte
171      TAF store directivs "byte" and "kind" seem equivalent;
172      Most tamc.h have been updated correspondingly.
173    
174    checkpoint61i
175    o autodiff:
176      fix autodiff_sore/_restore indices for obcs
177      (spotted by I. Hoteit, M. Mazloff)
178    o pkg/autodiff, pkg/ctrl:
179      Add flag to reduce all tapelev I/O to single-prec.
180      In data.ctrl set
181        doSinglePrecTapelev = .TRUE.
182    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
183      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
184    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
185      real fresh water flux (not yet)
186    o pkg/mdsio & rw:
187     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
188     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
189    o pkg/flt:
190     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
191       init_fixed & ini_varia.
192     - clean-up & simplify linear interpolation S/R:
193       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
194     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
195     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
196     - add vert. coordinate & horiz. indices to output files.
197     - change vertical position in initial condition, from index to depth [m].
198     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
199       (easier to get to a curvilinear grid) ; delX,delY no longer used.
200    o pkg/ggl90: a few modifications:
201     - fix bottom boundary condition, and interpolation of KappaE
202       near top and bottom
203     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
204     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
205     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
206    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
207      (maintain temporary backward compatibility, until next checkpoint)
208    
209    checkpoint61h
210    o pkg/diagnostics with "periodic averaging diagnostics":
211      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
212    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
213    o pkg/obcs: fix loop ranges for balancing code
214    o pkg/flt:
215     - improve criteria for finding which tile owns a float.
216     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
217    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
218      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
219      with ocean biogeo)
220    o pkg/flt:
221     - do some cleaning and fix the restart ;
222     - add output.txt in flt_example/results to get this pkg tested.
223    o genmake2: add an EXTENDED_SRC option and flag.
224       for now, cannot be turned on on command line (only through genmake_local)
225    o pkg/mdsio: read/write vector:
226     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
227     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
228       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
229     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
230      (drop to 4 digits matching for grad). But this test does not look very
231      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
232    
233    checkpoint61g
234    o pkg/flt:
235      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
236       + make OPTIONS file more standard.
237      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
238      - fix _BYTESWAPIO CPP-Flag
239      - standard reading of file-parameter "data.flt"
240      - fix argument list of S/R FLT_RESTART
241      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
242    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
243    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
244      a still unfixed compiler/optimization bug
245    
246    checkpoint61f
247    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
248      update results of global_ocean.cs32x15.icedyn test.
249    o move getcon.F from model/src to pkg/fizhi.
250    o pkg/exf: add parameter for extrapolation of temp up to the surface
251       and option to prevent negative evap (in bulk_largeyeager04 only).
252    o Prather Advection scheme: fix tracer conservation for divergent flow
253      (e.g., when using NonLin Free-Surface).
254    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
255    o gmredi (Visbeck-variable-K):
256     - add more parameters to Visbeck-variable-K.
257     - use a 5 points average for dSigmaR in Visbeck-K calculation
258       (more "homogenous": same stencil and same weights as in dSigmaH)
259     - update output of ideal_2D_oce experiment.
260    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
261      (#undef REAL4_IS_SLOW)
262     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
263       coordinate variable
264     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
265       (surface forcing fields), removes some of the functionality
266     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
267     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
268       probably not all: copy _RS surface flux fields to RL field before
269       calling DIAGNOSTICS_FILL
270     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
271       real*4 (CALL EXCH_*_RS) versions.
272     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
273       (generate new output).
274    
275    checkpoint61e
276    o gmredi (Visbeck-variable-K):
277      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
278      - change computation of Visbeck-K where Slope > Smax :        
279        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
280        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
281    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
282      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
283    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
284    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
285      does not become too large (to avoid precision problems in implicit-diffusion
286      solver); update ideal_2D_oce output.
287    o pkg ggl90:
288      - in ggl90_cal.F: compute only one set of visc/diff, used to
289        step forward TKE/T/S/momentum
290      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
291        have Prandlt =1)
292    o gmredi (fm07):
293      - add lower limit on Transition layer thickness + lower limit on 1/lambda
294      - allow to set few more params from data.gmredi
295    o pkg ggl90:
296          - add missing sqrt(2) factor in computation of mixing length
297            scale in ggl90_calc.F
298            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
299    
300    checkpoint61d
301    o adjoint modifs
302      - adapt to new field rhoInSitu
303      - allow to revert from StoreDynVars2D, StoreDynVars3D
304        to individual fields
305        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
306    o store 3-D (in-situ) density in commom block (DYNVARS.h)
307     - save 1 rho computation.
308     - no longer modify T & S inland when using down_slope pkg.
309    o gad_som : allow to switch to SOM advection for T & S without corresponding
310      pickup files (using new S/R: MDS_CHECK4FILE).
311    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
312      (for useSingleCpuIO to work in multi-threaded)
313    o pkg/shelfice:
314     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
315       with SHELFICEtopoFile in data.shelfice
316     - move code for reading ice shelf topography and modifying hFacC into separate
317       subroutines of the shelfice package
318     - separate initialisation of "fixed" and "variable" variables
319     - kTopC is not (yet) replaced by kSurfC, although this is possible
320    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
321    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
322      and rename:
323      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
324      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
325    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
326    
327    checkpoint61c
328    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
329      to add mass source/sink of fluid in the interior (3-D generalisation
330      of oceanic real-fresh water flux).
331    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
332    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
333    o new pkg: down_slope
334      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
335      - presently, modify T & S inland (dwnslp_calc_rho.F).
336        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
337      - implementation for ocean in P-coords not tested.
338      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
339    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
340      (to facilitate conversion of oceanic pkg to p-coordinate).
341    o change FIND_RHO to FIND_RHO_2D :
342      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
343    o new pkg: cheapaml
344    
345    checkpoint61b
346    o exch2:
347      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
348      - no longer depend on the order sequence (N,S,E,W).
349      - 3rd exchange no longer needed (tested with 24 tiles).
350      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
351      - exch_UV_A-grid readily available (but not yet tested).
352      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
353      (both are no longer needed) in exch_uv: no effect in forward run; but
354       get truncation error differences with adjoint exch.
355    o exch2:
356     - change index-bounds storage (moved from target to local tile,
357       more intuitive this way) ; rename/remove some variables.
358     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
359    
360    checkpoint61a
361    o exch2/matlab-topology-generator:
362      fix bug in index bounds for N-S internal exchange (hard to tell if this
363      had any effect on the solution).
364    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
365      is exceeded
366    o testreport: modify syntax of awk, so that it works also with
367      awk, and not only with nawk and gawk
368    
369    checkpoint61
370    o autodiff
371      Change default for TAF usage by removing argument '-nonew_arg'
372      This changes TAF subroutine argument list (ordering of active var.)
373      Omission of this flag leads to incompatibility w.r.t. TAMC
374      To restore TAMC-compatibility, need following modifs:
375      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
376      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
377      Tested TAF version is 1.9.22
378      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
379    
380    checkpoint60
381    --->>> This is the last checkpoint for which generating the adjoint
382    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
383    --->>> by default.
384    --->>> Future checkpoints will ommit this flag by default.
385    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
386    o pkg/grdchk: Add gradient check to etan0 perturbations.
387    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
388    o pkg/autodiff: more flexibility in zeroadj.
389      model/src: modifying do_oceanic_phys.F accordingly.
390    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
391    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
392      special setup of gmredi for which the adjoint is stable
393      enough for parameter optimization.
394    o bridging the gap between eddy stress and GM.
395      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
396          along with a change in CPP option (now ALLOW_EDDYPSI).
397      -> when using GM w/ GM_AdvForm:
398          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
399          is applied either in the tracer Eq. or in momentum Eq.
400          depending on data.gmredi (intro. GM_InMomAsStress).
401      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
402      The key modifications are in model/src/taueddy_external_forcing.F
403      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
404    
405    checkpoint59r
406    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
407      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
408      fix option to read coriolis(@ cell-corner) from files with CS-grid.
409    o pkg/mnc: add some attributes to standard 1D-coordinate variables
410    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
411      mass points, when using mnc for output
412      - add runtime parameter (missing_value, missing_value_int) to override
413        default (which is the value of getcon('UNDEF'))
414    o pkg/mnc: prepare mnc for the actual use of missing values with the
415      diagnostics package: small fix in mnc_cw_readwrite.template and more
416      initialisation of never used fields
417      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
418      versions
419    o pkg/thsice/thsice_ini_vars.F added default initial values so that
420      thermodynamics sea ice solver does not blow up when some initial fields
421      are missing.
422    o move from external_forcing_surf.F to ini_forcing.F
423      the p-coord. hack consisting in using pLoad to set phi0surf ;
424      update output of tutorial_global_oce_in_p (affected @ truncation level).
425    o Freshen up a bit hs94.1x64x5, notably:
426      remove rotationPeriod and tRef=5*0. (adjoint only), and add
427      exactConserv=.TRUE.
428    o pkg/generic_advdiff:
429      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
430      applies to files where Temperature & Salinity 2nd Order moments are used.
431    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
432      this uses a dynamically allocated internal state data structure
433      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
434      and requires a fortran 90 compiler
435    
436    checkpoint59q
437    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
438       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
439    o Refresh tutorial_global_oce_biogeo, notably:
440      - change bathymetry (put back seamounts in ACC, use hFacs)
441      - change EOS (POLY3 --> JMD95Z)
442      - use Bryan-Lewis vertical diffusivity
443      - use multidimensional advection
444      - remove old virtual virtual in dic pkg, now done through ptracer pkg
445      - change a couple of parameters in dic pkg
446    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
447    o pkg/obcs: change default to OBCSfixTopo = .true.,
448      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
449      - replace "debugMode" with "debugLevel .GE. debLevB"
450    o implementation of TAF directives for gchem,cfc,dic
451    o remove "exp5" (replaced by tutorial_deep_convection).
452    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
453      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
454      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
455      --> changes results in exp4, seaice_obcs
456    o tutorial_deep_convection :
457      update the set-up and increase resolution and domain size ; start
458      from pseudo initial conditions = output at t=120mn in order to see
459      something happening when running testreport.
460    o pkg/seaice: add os7mp as an advection scheme
461                  add check for advection schemes
462                  add a flag for restoring T and S underneath sea ice
463    o pkg/my82: add netcdf-support and diagnostics
464    o thsice pkg:
465      - Now hsMax limits snow height by turning it into ice following
466        flooding scheme (and now conserving energy)
467      - Slight rewriting of the formula in thsice_calc_thick.F
468      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
469      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
470    
471    checkpoint59p
472    o gchem / dic / cfc :
473      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
474      - add new parameter files: "data.dic" & "data.cfc" ;
475      - various re-arrangement in initialisation & header file ;
476      - fix tutorial_global_oce_biogeo for multi-threaded test.
477    o pkg/dic: test for "pickup_dic" file when restarting ;
478      if no pickup-file, can restart with a re-initialised pH (same as it did
479      before) providing pickupStrictlyMatch is set to False.
480    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
481      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
482    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
483      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
484    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
485     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
486       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
487    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
488       scheme to use for vorticty-term ;
489     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
490       (with default selectVortScheme, return to original discretisation)
491     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
492    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
493    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
494      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
495      also fix diagnostics VISCAHW & VISCA4W.
496    
497    checkpoint59o
498    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
499    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
500      move a few statemens out the main loop into separate loops
501    o pkg/shelfice:
502      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
503        (kg/m^2/s), does not break tests, because in verification/isomip,
504        rhoConstFresh=rhoConst (by accident)
505      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
506      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
507        new file model/src/seawater.F, so that they are available for all pkgs.
508      - convert potential temperature into in-situ temperature. This changes the
509        isomip tests => update tests
510    o add a flag writePickupAtEnd (default=true) to be able to suppress
511      writing a pickup at the last timestep
512    o tools/mpack-1.6 :
513      - disable automake (not working) and autoconf (not needed).
514      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
515        also cleaner with much less compilation warnings.
516    o pkg/profiles:
517      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
518      (for "less than 32 characters name" compiler requirement)
519    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
520      conditions that have a different sampling frequency than S/T/U/V obcs
521    o pkg/diagnostics (stats-diags):
522      - fix global Min/Max in case 1 processor get only empty tiles
523    o genmake2: replace (4 times)
524         make genmake_tc_1.o >> genmake_warnings 2>&1
525      with
526         COMM="$CC $CFLAGS -c genmake_tc_1.c"
527         echo $COMM >> genmake_warnings
528         $COMM >> genmake_warnings 2>&1
529      to make genmake2 always see the value of CC as specified in the optfile.
530    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
531      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
532      - modify verification advect_cs test to test SOM-advection on CS-grid.
533    o pkg/ctrl:
534      - Rewrite of ctrl_map_ini_ecco.F,
535        introducing a generic routine (ctrl_map_ini_gen.F).
536      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
537    
538    checkpoint59n
539    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
540      number in dedicate array "hdiag":
541      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
542        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
543      - many small changes (integer format) for large number of diagnostics
544      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
545        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
546    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
547      usingSphericalGrid, this allows to define the rotated grid coordinates
548      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
549      geographical coordinates according to the inverse of the rotation defined
550      by the Euler angles, so that Coriolis parameter and online-interpolation by
551      exf works with the geographical coordinates on XC/YC/XG/YG.
552      Naturally, this feature does not work with all packages, so some
553      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
554      profiles), because there the coordinates are assumed to be regular
555      spherical grid coordinates.
556    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
557      - introduce isopycnal diffusion coefficient control.
558    o tools/adjoint_options:
559      - additional control vector components.
560    o pkg/mnc: have mnc create marginally meaning full coordinate variables
561      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
562    o pkg/mypackage:
563      - add example of read/write pickup for state-var ;
564      - add entry points to the main code for state-vars diags & write-pickup.
565    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
566      transitions for useExfYearlyFields
567      - add new subroutine that determines the file to read from for
568        use*YearlyFields = .TRUE. and .FALSE.
569      - add a verification experiment to global_with_exf that tests
570        useExfYearlyFields with USE_EXF_INTERPOLATION defined
571    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
572      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
573      subroutines (which could be generated from a template, because they are
574      almost identical), for now they are included in obcs_prescribe_read.F for
575      simplicity
576    o pkg/exf:
577      - add a little more diagnostic to exf_interp_read (in analogy to
578        mds_read_field, can be turned off with debugLevel < debugLevA=1)
579      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
580        ugly but fast by unrolling short inner loops, inserting a unroll=8
581        directive in routine lagran, and splitting a loop and making do while the
582        outermost loop (the latter requires the intoduction of index arrays)
583    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
584    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
585      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
586    o verification/seaice_obcs: updated for restart test and latest options
587    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
588      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
589      for now this is only available for the C-grid code and also within
590      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
591    
592    checkpoint59m
593    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
594      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
595    o gad_som : fix flux output (& diagnostics) to have same units as other  
596      advection scheme fluxes (was previously multiplied by deltaT).  
597    o added verification/seaice_obcs both to test seaice open boundaries
598      and to provide an example matlab scrpt for generating them
599    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
600    o pkg/salt_plume: clean up salt_plume_frac.F to
601      remove redundancy in PlumeMethod 1 and 4
602    o pkg/kpp: added saltplume diagnostics
603    o pkg/obcs and pkg/seaice:
604      - do not set uice and vice to zero when OB*icefile are unspecified
605      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
606      - moved seaice tracer obcs after call to seaice_growth
607    o pkg/salt_plume: added various options for salt plume depth
608      criterion and for vertical distribution of the salt
609    
610    checkpoint59l
611    o pkg/ptracers: new version of ptracers pickup:
612      read meta file and write only fields which are needed to restart.
613      ( same logic as main pickup file ; also using pickupStrictlyMatch )
614    o pkg/seaice:
615      - add timescale for melting due to warm mixed layer as a means of
616        setting SEAICE_availHeatFrac more conveniently
617      - add a CPP-flag/runtime parameter check for flooding algorithm
618      - reformulated availHeat in seaice_growth.F to be independent of AREA
619    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
620      unit changes
621    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
622    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
623      SX vector computer.
624    o pkg/seaice:
625      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
626        seaice forcing fields can now be read only through pkg/exf
627      - removed some unused halos
628    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
629    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
630      or U/VICE from U/VWIND before computing U/VSTRESS
631    
632    checkpoint59k
633    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
634      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
635    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
636      all experiments pass when compile with un-initialised var. checking option.
637    o added pkg/salt_plume
638    o script to test restart (for now, in MITgcm_contrib/jmc_script)
639    o pkg/seaice: new read/write pickup version.
640      read meta file and write only fields which are needed to restart.
641      ( same logic as main pickup file ; also using pickupStrictlyMatch )
642    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
643    o lab_sea.hb87: modify the domain & update output.hb87.txt :
644      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
645      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
646      process. Fixed here by closing the domain at the Northern boundary.
647    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
648    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
649      a set of consecutive levels in/from a 3-D array.
650    o pkg/ptracers:
651      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
652      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
653    
654    checkpoint59j
655    o in pkgs: dic, obcs, offline, rbcs:
656      standard way to compute coeff. for time interpolation between 2 time reccords
657      which retains full precision (& make results less dependent on compiler).
658      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
659    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
660      packages instead of reading ice cover and wind speed separately
661    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
662     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
663      to allow to compile customized code before the update)
664    o cleaning-up:
665      - fix CPP instruction syntax in pkg/obcs
666      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
667        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
668      - fix some threads issue in IO parts.
669    o pkg/dic:
670      - add tons of "_d 0" (--> much better testreports !)
671       and then update outputs of tutorial_global_oce_biogeo
672    o pkg/mom_fluxform:
673      add a special version of momentum advection intended to conserve momentum
674      next to a bathymetry step or a coastline edge. (default = off = #undef)
675    o new read/write pickup version:
676      - for now, only implemented for main (mdsio) pickup file.
677      - write out only what is needed to restart; merge pickup_nh , pickup_ph
678        and main pickup together.
679      - read meta file; read only what is needed to restart; stop if a field
680        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
681        if it make sense (even if the restart is not perfect).
682      - if no meta file, assume that pickup to read corresponds exactly to
683        a pickup that would currently be written.
684      - read pickup written in the old format (until checkpoint59i) if it
685        recognizes an old meta file (no field-list).
686      - add a meta file in exp. which starts from a pickup: 2 cases:
687        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
688         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
689        b) a meta file describing the content of the associated pickup file
690         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
691    o pkg/mdsio & pkg/rw:
692      - new routine to read a meta file ; new set of routine to read
693        Multiple-fields file (with meta file).
694    o added open boundary conditions capability for seaice
695        HSNOW, HSALT, UICE, and VICE
696    
697    checkpoint59i
698    o adjoint:
699      * fix multiDimAdvection adjoint
700        (partial recomputation problem by TAF for fVerT(:,:,kDown)
701        and comlev1 size definition (maxpass vs. max. number of tracers)
702      * verification/global_ocean.90x45x15 adjoint now tests
703        NLFS and multiDimAdvection using DST3 (=30)
704      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
705    o pkg/kpp: add "_d 0" to real constant (if missing);
706      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
707      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
708    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
709      for internal parameters related to restart process (formerly from PARAMS.h)
710      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
711    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
712      as argument. (only atm2d & obcs write_pickup have not yet been updated)
713    o pkg/monitor:
714      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
715      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
716      - account for deep Atmosphere factor and density factor (anelastic)
717    o added open boundary conditions capability for seaice HEFF and AREA
718    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
719      thermodynamics
720      - requires a little reorganization, which affects the testreport results
721        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
722        so that now the conservative form is tested
723      - add a few comments
724    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
725    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
726    o add new diagnostics to seaice: advective, diffusive fluxes (only for
727      multidim-advection, for scheme 2 they are not filled) and transports,
728      thermodynamic growth rates
729    o change units of EmPmR (inside the code, + within coupling interface)
730      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
731      Affects results @ truncation level (cg2d match) and update output of
732       experiments: lab_sea(6), global_ocean.90x40x15(10),
733      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
734      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
735      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
736      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
737    
738    checkpoint59h
739    o pkg/exf:
740      - improve vectorization by moving if-statement out of loops in
741        exf_mapfields, exf_radiation
742      - exf_bulkformulae.F: introduce 2D fields and vectorize code
743    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
744    o testreport:
745      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
746        monitor & update offline_exf_seaice exp. output.
747      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
748    o pkg/seaice:
749      - bug fix in the evp solver: boundary conditions were affected be
750        masking of zMax/zMin (changes results)
751      - minor bug fix in boundary conditions in seaice_calc_strainrates
752        (changes results for no_slip)
753      - seaice_lsr.F: make interpolation of eta dependent on boundaries
754      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
755      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
756        stress formulation and no-slip boundary conditions
757    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
758      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
759    o pkg/seaice: a first HSALT time stepping equation has been checked in
760    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
761      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
762      without requiring DO-IF statements
763    o pkg/thsice:
764      use continuous power-law function for partition of energy between lateral
765      melting/freezing and thinning/thickening ; old code using step function
766      still available with #undef THSICE_FRACEN_POWERLAW
767      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
768    o testreport: change AD testing : check against results/output_adm.txt
769      using same scripts as for forward test.
770    
771    checkpoint59g
772    o adjoint testing: in preparation for changing testreport:
773      - output format: cost and grad written on separated lines
774      - ad output results in directory "results" (instead of "results_ad")
775    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
776    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
777    o pkg/ecco: allow user defined cost function contributions
778    o testreport:
779      Allow to choose (per experiment) the list of tested output variables
780       and the main variable (used to issue a pass/FAIL ) ;
781      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
782      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
783      Also modify printing of summary:
784       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
785       b) echo the list of tested variables in the individual summary.txt of
786          each experiment.
787    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
788      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
789      (but still depend on the tile decompostion of the domain).
790    o pkg/seaice: change a discretization detail to make the B-grid code
791      "more symmetric". This change is likely to remove all "ridges/leads" that
792      where quasi-aligned with the grid in B-grid solutions. It may also be
793      the solution to the stress coupling issues with the B-grid.
794    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
795      remove .cvsignore from input dir. (since testreport no longer run here).
796    o pkg/thsice:
797     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
798     - fix reshaping of sea-ice just after advection:
799       melt all the ice only if ice-volume is too small.
800     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
801       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
802     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
803    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
804      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
805    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
806      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
807      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
808      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
809      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
810      -> update output.txt
811    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
812     this affects truncation error: -> update output.txt of exp:
813      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
814      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
815    
816    checkpoint59f
817    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
818    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
819      a bounded range (in forward mode)
820    o pkg/ecco, ctrl, autodiff and mom_common:
821     internal parameter controls, completements of implementations
822    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
823    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
824      (not seem any difference in testing results).
825    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
826       at face corners.
827    o pkg/generic_advdiff:
828     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
829      loop range indices for computing vertical advection tendency
830      and do the calculation in the interior only (no overlap) ;
831      for now, only implemented for SOM advection (to save CPU time).
832     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
833    o exch2 adjoint
834      First set of changes:
835      - add exch2 hand-written adjoint templates
836      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
837        This will require cleanup in pkg/autodiff/*.F
838        (changed routines currently kept separate in verif. code/)
839      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
840        that used to hide exch2 or cubed-sphere specific code
841        (commented via 'cph-exch2')
842    o pkg/seaice
843      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
844    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
845       output of global_ocean.cs32x15.thsice .
846    
847    checkpoint59e
848    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
849      for B-grid vector (not yet tested) and C-grid vector (<- only used
850      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
851    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
852      (#ifdef ALLOW_SALT_PLUME)
853    o gather_2d/scatter_2d: removed halo regions
854    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
855      scheme and the corresponding test case (under front_relax dir). For now,
856      only available with Skew-flux form and not yet tested in realistic set-up.
857      adjoint: store directives updated, but gradient checks deteriorated,
858      so maybe GM/Redi adjoint is now broken.
859    o seaice adjoint
860      * add AREA, HEFF, HSNOW as control variable
861        (should not change lab_sea results)
862      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
863    o pkg/seaice:
864      * added computation of saltFlux in seaice_growth;
865        For time being, sea ice salinity is assumed constant
866        contribution of snow flooding to freshening of sea ice is neglected.
867        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
868        defaults to 0.0 in order to maintain backward compatibility.
869        Typical values for SEAICE_salinity are 4 to 10 g/kg.
870      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
871      * added SEAICE_availHeatFrac, which specifies fraction of surface level
872        heat content used to melt or grow ice
873      * commented out cap of HICE: it helps keep ice thinner
874      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
875      * applied OBCS T/S mask to HEFFM sea ice mask
876    
877    checkpoint59d
878    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
879     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
880     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
881    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
882     and change default value of parameter "GM_Small_Number";
883     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
884       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
885       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
886    o pkg/ecco: cost function when applying pkg/smooth to controls
887    o pkg/ctrl: add forcingPrecond run time parameter
888    o pkg/seaice:
889     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
890     - fix bug in metric terms of u-equation in LSR solver (implicit part),
891       changes verification/lab_sea
892     - rearrange implicit part of u-equation in LSR solver to make it easier to
893       read, understand, and debug. This causes changes at the truncation level.
894     - fix (serious) bug in the boundary conditions (sign error in the implicit
895       part) of the LSR solver. Changes all LSR results.
896     - fixed problem with HSNOW initialization to avoid thick snow when AREA
897       is initilized with small values - does not change lab_sea results.
898     - added HsnowFile initialization capability
899    o pkg/smooth: addition to model/src and pkg/ctrl so allow
900     initialization of pkg/smooth and application to control vector
901    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
902    o dependencies: pkg/profiles requires pkg/cal
903    o pkg/profiles:
904     - added option ALLOW_PROFILES_GENERICGRID
905         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
906         that interpolation information (grid points and coefficients) is provided
907         within the netcdf input files.
908         -> sample matlab scripts can be found in MITgcm_contrib/gael
909         that allow you to prepare netcdf input files.
910     - also modified: cleaner include statements, cleaner error print statements,
911       cleaner stops when error, and more tests of the netcdf input files consistency.
912    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
913    o pkg/seaice:
914     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
915       requires a new routine: seaice_diagnostics_fill.F
916     - make sure that seaice does not move if not forced (pressure replacement
917       method, Hibler and Ip, 1995), changes results
918     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
919     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
920       It is turned off by default (=-1.), because it changes the results.
921     - make it possible to read AREA from a file, too.
922    
923    checkpoint59c
924    o add S/R and diagnostics for oceanic mixed-layer depth
925    o move GMRedi call after all vertical mixing schemes (including KPP)
926    o pkg/thsice:
927     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
928      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
929    o pkg/obcs:
930     - bug fix for balance code
931    o pkg/seaice:
932      - allow values of SEAICE_elasticParm > 1
933      - add new parameter SEAICE_evpTauRelax as an alternative
934        to SEAICE_elasticParm
935      - make lsr boundary conditions free slip (by default), changes result
936      - add code for no slip boundary conditions for lsr
937      - set minimum of zeta to zero (and not 4e8) (changes results)
938      - add a cap on AREA after advecting AREA if seaice_growth is not called
939    o change calculation of Visbeck K:
940      - no longer depend on tapering scheme; instead, compute slope (limited
941        by GM_maxSlope). this is equivalent to what was comuted before with
942        clipping or linear tappering.
943      - fix vertical averaging (wrong by 1/2 level)
944      - leave the old version (but will not be maintained) within
945        #ifdef OLD_VISBECK_CALC / #endif
946      - update output of exp. ideal_2D_oce
947    o change error catch in calc_r_star to improve vectorization
948    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
949      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
950    o adjoint:
951      Re-organized adjoint checkpointing according to Matt Mazloff
952      (but with modifs/completions/cleanups)
953      Storing is now bundled into large arrays to optimized I/O
954      (and second step in cleanup of the_main_loop)
955    
956    checkpoint59b
957    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
958      - export/import (between ocean & coupler) fields needed for ocean DIC.
959    o pkg/seaice:
960      - get rid of three more exchanges seaice_calc_viscosities (required
961        different loop boundaries in seaice_lsr and seaice_ocean_stress)
962      - bug fix in seaice_ocean_stress (update of lab_sea required)
963      - reduce loop boundaries to necessary minimum also in seaice_evp
964      - go back to the old way of computing deltaC/Z as the adjoint likes that
965        better
966    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
967      passive tracer to an Age Tracer) + update output.txt
968    o pkg/exf:
969      - implement A-grid / C-grid selection for wind-stress input files.
970      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
971      for now, in exf_bulk_largeyeager04.F only :
972      - change implementation for case where windspeed + 2. components wind-stress
973        are read-in. AND use rhoConstFresh to convert evap.
974    o pkg/seaice:
975      - use correct EXCH_UV for wind-forcing (on A-grid).
976      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
977        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
978    o pkg/exf:
979      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
980      EXF_INTERPOLATION:
981      - merge global_with_exf/code version of exf_interp_read.F
982        to the main code ;
983      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
984        reading the file ; Important: This options needs to be defined to recover
985        previous code.
986        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
987      - no longer loose real*8 precision along the way when using exf_iprec=64.
988    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
989      - change discretisation of evp-solver in order to avoid another exchange
990        (changes lab_sea) and clean up a little
991      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
992        help the adjoint (this also changes the results slightly)
993      - add a few "_d 0" where they had been missing in seaice_evp.F
994      - cleaning up: remove unused seaice_calc_rhs.F
995    o pkg/exf: some cleaning-up:
996      - change various "constants" into runtime parameters
997      - cleaned-up Large&Yeager04 routine which should eventually
998        replace exf_bulkformulae.F (changed names of S/R and CPP)
999        and merged various ALLOW_ATM_WIND options
1000     only used with thsice pkg (in thsice_get_exf.F):
1001      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1002        which are used when useStabilityFct_overIce=TRUE (= the default)
1003      - change default values of ice & snow emissivity and scale downward LW
1004        by ice & snow emissivity.
1005    o pkg/thsice:
1006     fix few little problems, in thsice_calc_thickn.F:
1007      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1008      - melt only laterally if hIce < hThinIce (as the comments say)
1009      and in thsice_extend.F:
1010      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1011      - start to form ice as soon as the minimum ice-volume is reachable.
1012     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1013      and cpl_aim+ocn
1014    o pkg/kpp
1015     - move computation of surface related input fields to KPP into a new
1016       subroutine kpp_forcing_surf.F
1017     - remove wrong (within bi,bj loops) EXCH calls.
1018     - little cleaning (add argument myThid in last position, cvs header ...)
1019     - for now, fix conservation problem by exchanging KPPviscAz (may not
1020       be the best fix)
1021    o pkg/seaice
1022     - check for inconsistent evp parameter/cpp-flag combination
1023     - remove leftover errIO flat for obsolete name list error handling
1024    o OpenAD
1025     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1026    
1027    checkpoint59a
1028    o pkg/seaice: some parameter clarifications and a little bit of clean up
1029    o pkg/thsice: rename run-time parameters:
1030       himin       -> hIceMin
1031       himin0      -> hThinIce
1032       hihig       -> hThickIce
1033       i0          -> i0swFrac
1034       transCoef   -> bMeltCoef
1035       frac_energy -> fracMelting
1036      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1037       with default values (for now) that do not change the results.
1038      remove old version of thsice vars advection in pkg/seaice.
1039    o in FFIELDS.h:
1040      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1041      - make pLoad & sIceLoad always available (but still only used if
1042         ATMOSPHERIC_LOADING is #define).
1043    o pkg/kpp: replaced _KPP_RL with _RL
1044    o bug fixes for vertical diffusivity computations when both KPP and
1045        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1046        are no longer updating the vertical diffusivity array
1047        (passed as argument) but are (re-) setting those arrays.
1048    o pkg/seaice: fix bug in evp solver, while doing that
1049      - change (improve?) discretization of stress computations for both
1050        cgrid-lsr and evp solver
1051      - add a new routine to compute strain rates
1052      - the above changes lab_sea results
1053      - add no slip conditions for evp solver (off by default), lsr-version
1054        may follow
1055      - fix exchange for shear at Z-points (does not change lab_sea)
1056      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1057        (to force the user to pick a time step since there is not "safe" way
1058        of choosing it)
1059      - add principal stress diagnostics
1060      - rearrange fields for evp a little to avoid having to call a: too many
1061        exchanges and b: exchanges for stress trensor components which we do
1062        not have.
1063      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1064        of evp, complete rewrite for lsr case (latter is does not yet work
1065        in all cases)
1066    o pkg/kpp: add code to have mixing in shelf ice caverns
1067      - add myThid to all kpp routines (long overdue)
1068    
1069    checkpoint59
1070    o pkg/exf:
1071      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1072        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1073      - move exf header files from lower_case.h to UPPER_CASE.h ;
1074        add missing cvs Header & Name
1075      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1076      - add namelist param. selectStressGridPosition, exf_monFreq
1077      - retire many _CLIM routines, and remove data.exf_clim
1078        + params moved to data.exf
1079        + climsst, climsss now handled by exf_set_gen, i.e.
1080          climss?period=0 refers to constant field,
1081          climss?period=-12 to monthly forcing
1082      - split up namelists in data.exf
1083    o pkg/seaice:
1084      - remove seaice_exch and seaice_exch_uv
1085      - remove superfluous exchange of theta
1086      - add myThid to seaice_budget_ocean/ice
1087      - add new interface for atmospheric wind forcing (C-grid only)
1088        + new routine
1089        + two new field (taux, tauy for stress over ice)
1090        + removed one global field (DAIRN) for C-grid case only
1091    o pkg/thsise
1092      - 2nd set of modifs for thsice adjoint in conjunction with exf
1093    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1094    
1095    checkpoint58y_post
1096    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1097      vertical diffusivity, similar to that in MOM4; turned on using
1098      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1099      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1100    o Added capability for 3D specification of background vertical diffusion
1101      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1102      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1103      "data" file that contains the 3D vertical diffusivity coefficients.
1104    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1105      - add code within pkg thsice to advect & diffuse sea-ice fields
1106      similar to (and will replace) what has been added in  seaice_advdiff.F,
1107      but: - conserving Mass, Heat & Salt.
1108           - better when using non-linear advection scheme (not yet fully tested)
1109           - can also be used in atmospheric set-up (for now, only the diffusion).
1110    
1111    checkpoint58x_post
1112    o IO option for global-file compact format:
1113      - add options when generating topology (utils/exch2/matlab-topology-generator)
1114      - add I/O capability (pkg/mdsio).
1115      - adapt utils/matlab/rdmds.m to read this format.
1116      for now long-line format not yet supported by pkg/mdsio (& exch2).
1117    o shelfice: add a few diagnostics
1118    
1119    checkpoint58w_post
1120    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1121      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1122      (and replace horiVertRatio in NH code).
1123      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1124                         and tutorial_plume_on_slope (sensitive to truncation)
1125    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1126      directly to drive seaice model (C-grid only)
1127    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1128     - reintroduce computation of wind from stress,
1129     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1130       mass points to avoid tau = 0
1131     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1132    o rdmnc.m: make it work with "global" files created with gluemnc
1133    o rdmnc.m : some improvements in dealing with singleton dimension
1134      (tested on all testreport mnc output files).
1135    o genmake2: disable pkg/profiles if netcdf test fails.
1136    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1137    o move call to cal_readparms up to make calendar parameters/variable available
1138      to all packages
1139    
1140    checkpoint58v_post
1141    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1142      useDynP_inEos_Zc tested.
1143  o pkg/exf: changes to properly interpolate/mask/scale initial fields  o pkg/exf: changes to properly interpolate/mask/scale initial fields
1144  o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields  o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
