4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/obcs:
8      - change OB?eta from _RS to _RL and put them into a separate commen block
9      - add code to read OB?eta from a file via obcs_prescribe_read: the code
10        compiles and does not destroy any other experiments, the data is read
11        properly, but the code is not tested in actual applications
12    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
13      create a meaningful unit attribute for the time coordinate variable
14    o pkg/ebm: add plenty of missing "_d 0" ;
15       update results of experiment global_ocean_ebm (fwd + adjoint tests)
16      Notes: several pieces of code only works for (very) specific set up
17       (domain size, lat range, etc ...); should be documented & stop if one
18       of those assumptions is not meet.
19    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
20       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
21          and offline_exf_seaice (seaicetd + adjoint).
22    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
23       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
24        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
25    o few changes to pass when compiling with strick checking of arguments
26       across S/R (allow to find few bugs in S/R calls).
27    o pkg/seaice:
28     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
29       2d-fields, for slightly better performance
30    
31    checkpoint61t
32    o pkg/seaice:
33     - remove unused variables in seaice_evp
34     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
35    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
36       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
37       each processor opens a different file (a fix from Matt).
38    o cg2d:
39       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
40       this reduces number of EXCH calls by 2 when using exch2.
41       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
42       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
43    o pkg/thsice:
44       add code for Near Infra-Red albedo (from Jeff)
45       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
46    o ini_model_io:
47       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
48       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
49       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
50    
51    checkpoint61s
52    o pkg/exch2 (exch2_rxN_cube*):
53       remove last BARRIER (no need to synchronise after getting data from shared
54       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
55    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
56      and generate new output (for the 2 tests) using default rotationPeriod.
57    o pkg/exch2:
58      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
59        (was already the case with AUTODIFF_EXCH2 defined)
60      - add bj in exch2 arrays and S/R.
61      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
62        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
63    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
64      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
65        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
66      - verification experiment natl_box.longstep
67    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
68      allow different versions of ifort (8 or 9) and different versions
69       of mpi (mpich or mpich2) to be used with the same optfile.
70      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
71       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
72    o pkg/seaice:
73      fix previous modif (3-level field removed) for old-pickup reading
74    
75    checkpoint61r
76    o pkg/seaice:
77     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
78      1. introduce fields for time step (N-1)
79      2. do not use levels 2 and 3 anymore (but keep them)
80      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
81         includes changes to pkg/thsice/thsice_get_velocity.F,
82         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
83         pkg/obcs/obcs_apply_uvice.F.
84     - completely remove code for leap-frog time stepping for second order
85       advection
86     - adjusted adjoint accordingly;
87       gradient checks have improved by an order of magnitude!
88    
89    checkpoint61q
90    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
91     - the boundary conditions along open boundaries are unclear, because the
92       associated masks are set to zero and are thus treated as closed when
93       applying the slip-boundary conditions.
94     - move initialisation of grid variables from seaice_init_varia to _fixed
95    o adding doc/diags_changes.txt
96    o model/src:
97      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
98       to avoid "_diags" naming if no relation to pkg/diagnostics.
99      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
100       file and only call PLOT_FIELD_XYZ if debugMode=T.
101      remove few PLOT_FIELD_XY calls outside initialisation.
102      remove few unnecessary BARRIER.
103    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
104      of salt_plume package in Southern Ocean
105    o pkg/thsice:
106     - fix hOceMxL in overlap (needed for sea-ice advection);
107       update output of experiment global_ocean.cs32x15.icedyn.
108    o pkg/seaice:
109     - make the (placeholder-)tracer IceAge a little more meaningful
110      by avoiding ridging of age due to convergent ice flow
111     - add diagnostics for surface temperature, atmospheric and oceanic
112       heat flux, and atmospheric and oceanic ice growth
113    
114    checkpoint61p
115    o eesupp (global_max & global_sum):
116     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
117     - remove starting & endding barrier (no longer needed)
118    o pkg/mdsio, writelocal:
119       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
120       (remove the STOP): uses shared buffer IO to store data from all threads
121       and then let master-thread write nThreads tiles.
122    o pkg/mdsio (read/write field):
123     - tiled IO done in 1 piece (all levels at a time);
124     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
125     - multi-threaded: allow to read/write local (non-shared) array
126       (was already working with singleCpuIO ; now works also without);
127       => no longer needs barrier call after reading a file (added inside
128       mds_read/write field).
129     - move barrier calls outside gather/scatter_2d to mds_read/write_field
130    o pkg/obcs/exf
131      - exf_getffieldrec.F: add a few ". _d 0" and
132                            add code to catch the case fldperiod = 0.  
133      - obcs_precribe_read.F: change if statements so that they match
134                              the variable type (_RL)
135      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
136        exf_iprec) as part of namelist EXF_NML_01
137    o pkg/mdsio:
138      - read/write tiled (local) files: read/write 1-level tile chunk at a time
139        (instead of segment of length sNx); expected to speed up tiled IO.
140    o pkg/exch2:
141      - take buffer copy from/to array out of S/R exch2_send/recv into new
142        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
143        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
144      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
145      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
146        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
147        including Topology header file (and common blocks).
148      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
149        remove 2nd exch call in exch2_s3d_rx (no longer needed).
150      - document S/R arg. list (+ update some comments)
151    o pkg/seaice:
152      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
153        temperature and humidity over sea ice based on climatological values.
154      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
155        of LSR (this change is expected to change the results slightly because now
156        it uses slightly difference moduli from the second last LSR solution, but
157        that is more consistent with the stress computations; this part of the code
158        is not tested in the verification experiments)
159      - fix diagnostics for flux of ice in case of B-grid
160      - turn strain rates eij and press into global fields within global
161        common block in SEAICE.h for more straighforward diagnostics
162      - fix diagnostics for principal stress components, press, zeta, eta
163        to give something meaning full
164    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
165      new output (all 4 tests) using default rotationPeriod.
166    o pkg KPP:
167      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
168      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
169        and normal grid from 1 to Nr)
170    o Fix computations of L4rdt in mom_calc_visc.F
171    o eesupp:
172      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
173      should be called before a "stop" if we know that all process are going
174      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
175    
176    checkpoint61o
177    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
178    o model/src/ini_curvilinear_grid.F:
179       compute angleSin/CosC when they are not read from a file
180    o pkg/seaice:
181       add pseudo time stepping for LSOR
182    o pkg/exch2:
183       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
184    o pkg/seaice:
185       Adding separate sea ice albedo, drag coefficients, and HO in Southern
186       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
187    o SingleCpuIO:
188       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
189    o pkg/seaice:
190       put exchanged variable in (local) common block for MPI+Multi-Threads
191       to work (necessary with exch1, and for now with exch2 too).
192    o verification: to get more experiments tested with mpi, mth and mpi+mth,
193      change tiling of:
194       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
195       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
196      update output of exp:
197       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
198       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
199      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
200                       (note: output.txt generated on faulks using only 1 tile)
201    o eesupp & mdsio (SingleCpuIO):
202     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
203       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
204       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
205     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
206     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
207       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
208    o pkg/exch2:
209     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
210       read parameter file "data.exch2" if it exists; otherwise try default regular
211       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
212     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
213       with new code (not to be used, just as a backup solution).
214     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
215       in utils/exch2/input.
216    
217    checkpoint61n
218    o eesupp & mdsio (SingleCpuIO):
219      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
220        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
221        receive real*4 array (instead of real*8) to read/write 32.bit files.
222        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
223         and remove new mapping S/R)
224    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
225      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
226        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
227        when using exch2. Add S/R to map global io-buffer to global model array.
228      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
229    
230    checkpoint61m
231    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
232      and add 3 other S/R for other types (R4,R8,RS).
233      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
234    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
235     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
236     - reduce number of macro definitions (keep only those which are used);
237       can always call directly the corrresponding S/R if needed.
238     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
239       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
240     Fixed wrong type of arg in:
241       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
242       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
243     To fix: global_sum of var in common block is wrong (multi-threaded) in:
244       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
245     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
246    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
247      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
248    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
249    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
250      edges are closed (zero depth); might happen with "blank tiles";
251      for now, disabled if using OBCS.
252    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
253      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
254    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
255      to reduce length of 1.D array print in STDOUT.
256    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
257      + use 48 tiles (16x8): this will allow to test "blank tiles".
258    o start to test MPI + multi-threaded (change testreport to skip tests
259      where number of tiles do not match).
260    o genmake2: add option "-omp" to turn on Open-MP ;
261      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
262    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
263      and keep the original tile numbering. Note: compatible with old
264      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
265    
266    checkpoint61l
267    o Overlaps had been forgotten in calculating ijk keys : fixed
268    o fix cyrus makedepend for gcc 4.4
269    o experiment fizhi-cs-aqualev20:
270      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
271      and generate new output. Note: new output is much closer to the old
272      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
273      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
274    o pkg/fizhi:
275     - change to avoid indices going deliberately over array-bounds
276     - remove unnecessary MPI stuff
277     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
278     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
279       does not go over array-bounds and therefore returns reliable output.
280     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
281       this S/R has 4 output arguments, which are used inside "get_alarm";
282       when it is called with the same variable "ndum" in place of several
283       output arguments, this produces weird side effect inside "get_alarm"
284      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
285       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
286       address) and produces error.
287    o tools/gemake2: (March 27-29 2009)
288      with option "-mpi": link *_mpi files from "MODS" dir (this is what
289      testreport does).
290    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
291    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
292       update lab_sea.lsr & lab_sea.salt_plume results
293    o pkg/seaice:
294      Major overhaul of the LSOR solver: change discretization from original
295      finite differences to finite volume. The old routine is still in the
296      file seaice_lsr.F and can be turned on with the CPP-flag
297      SEAICE_OLD_AND_BAD_DISCRETIZATION
298      Along with this change, the discretization of the strain rates is changed.
299      The same flag turns on the old discretization in seaice_calc_strainrates.F
300      All verification experiments with seaice are affected (except for
301      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
302      results by setting the above flag.
303      Further changes involve changes in defaults:
304      - ALLOW_FLOODING is defined and turned on by default
305      - SEAICEadvSnow = .true. is now the default
306      - SEAICEadvSalt = .true. is now the default
307      - SEAICEadvAge  = .true. is now the default
308      - SEAICE_clipVelocities  = .false. is now the default
309                                         (as per J. Zhang's recommendation)
310      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
311        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
312      - seaice_growth: replace computation of UG by a simple copy from wspeed
313    
314    checkpoint61k
315    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
316      seaice_lsr: fixed a few metric terms,
317                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
318                  add more debugging diagnostics
319      seaice_evp: removed superfluous many metric terms of FV discretization
320                  of stress divergence
321                  affects lab_sea, lab_sea.hb87
322      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
323                  of stress divergence for non-evp solver
324                  (this part is not tested anywhere)
325      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
326                  they were effectively only half slip
327                  affects lab_sea.hb87
328      updated all relevant verification experiments (except lab_sea//output_adm.txt
329        which was left over, but fails at level 7 & 6)
330    
331    checkpoint61j
332    o pkg/seaice: turn a few hard wired parameters into run time parameters
333    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
334      time in seconds as promised by the usints in seaice_monitor and exf_monitor
335    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
336      that are not cubed-sphere grids
337    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
338    o pkg/ctrl:
339      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
340    o non-hydrostatic (calc_gw.F):
341      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
342      update output of exp. global_ocean.cs32x15.viscA4
343    o remove backward compatibility for thetaMin,phiMin
344      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
345    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
346      interpolated wind field not only for curvilineargrid=.true., but also
347      for a rotated grid (rotateGrid=.true.)
348    o pkg/exf: add capability to bypass interpolation for runoff
349      by setting yet another CPP-flag
350    o eesupp/src, B-grid exchange:
351      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
352    o autodiff
353      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
354      allows to switch to single-prec common blocks;
355      corresponding switch occurs in tamc.h, integer isbyte
356      TAF store directivs "byte" and "kind" seem equivalent;
357      Most tamc.h have been updated correspondingly.
358    
359    checkpoint61i
360    o autodiff:
361      fix autodiff_sore/_restore indices for obcs
362      (spotted by I. Hoteit, M. Mazloff)
363    o pkg/autodiff, pkg/ctrl:
364      Add flag to reduce all tapelev I/O to single-prec.
365      In data.ctrl set
366        doSinglePrecTapelev = .TRUE.
367    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
368      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
369    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
370      real fresh water flux (not yet)
371    o pkg/mdsio & rw:
372     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
373     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
374    o pkg/flt:
375     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
376       init_fixed & ini_varia.
377     - clean-up & simplify linear interpolation S/R:
378       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
379     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
380     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
381     - add vert. coordinate & horiz. indices to output files.
382     - change vertical position in initial condition, from index to depth [m].
383     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
384       (easier to get to a curvilinear grid) ; delX,delY no longer used.
385    o pkg/ggl90: a few modifications:
386     - fix bottom boundary condition, and interpolation of KappaE
387       near top and bottom
388     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
389     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
390     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
391    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
392      (maintain temporary backward compatibility, until next checkpoint)
393    
394    checkpoint61h
395    o pkg/diagnostics with "periodic averaging diagnostics":
396      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
397    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
398    o pkg/obcs: fix loop ranges for balancing code
399    o pkg/flt:
400     - improve criteria for finding which tile owns a float.
401     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
402    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
403      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
404      with ocean biogeo)
405    o pkg/flt:
406     - do some cleaning and fix the restart ;
407     - add output.txt in flt_example/results to get this pkg tested.
408    o genmake2: add an EXTENDED_SRC option and flag.
409       for now, cannot be turned on on command line (only through genmake_local)
410    o pkg/mdsio: read/write vector:
411     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
412     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
413       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
414     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
415      (drop to 4 digits matching for grad). But this test does not look very
416      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
417    
418    checkpoint61g
419    o pkg/flt:
420      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
421       + make OPTIONS file more standard.
422      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
423      - fix _BYTESWAPIO CPP-Flag
424      - standard reading of file-parameter "data.flt"
425      - fix argument list of S/R FLT_RESTART
426      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
427    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
428    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
429      a still unfixed compiler/optimization bug
430    
431    checkpoint61f
432    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
433      update results of global_ocean.cs32x15.icedyn test.
434    o move getcon.F from model/src to pkg/fizhi.
435    o pkg/exf: add parameter for extrapolation of temp up to the surface
436       and option to prevent negative evap (in bulk_largeyeager04 only).
437    o Prather Advection scheme: fix tracer conservation for divergent flow
438      (e.g., when using NonLin Free-Surface).
439    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
440    o gmredi (Visbeck-variable-K):
441     - add more parameters to Visbeck-variable-K.
442     - use a 5 points average for dSigmaR in Visbeck-K calculation
443       (more "homogenous": same stencil and same weights as in dSigmaH)
444     - update output of ideal_2D_oce experiment.
445    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
446      (#undef REAL4_IS_SLOW)
447     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
448       coordinate variable
449     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
450       (surface forcing fields), removes some of the functionality
451     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
452     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
453       probably not all: copy _RS surface flux fields to RL field before
454       calling DIAGNOSTICS_FILL
455     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
456       real*4 (CALL EXCH_*_RS) versions.
457     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
458       (generate new output).
459    
460    checkpoint61e
461    o gmredi (Visbeck-variable-K):
462      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
463      - change computation of Visbeck-K where Slope > Smax :        
464        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
465        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
466    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
467      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
468    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
469    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
470      does not become too large (to avoid precision problems in implicit-diffusion
471      solver); update ideal_2D_oce output.
472    o pkg ggl90:
473      - in ggl90_cal.F: compute only one set of visc/diff, used to
474        step forward TKE/T/S/momentum
475      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
476        have Prandlt =1)
477    o gmredi (fm07):
478      - add lower limit on Transition layer thickness + lower limit on 1/lambda
479      - allow to set few more params from data.gmredi
480    o pkg ggl90:
481          - add missing sqrt(2) factor in computation of mixing length
482            scale in ggl90_calc.F
483            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
484    
485    checkpoint61d
486    o adjoint modifs
487      - adapt to new field rhoInSitu
488      - allow to revert from StoreDynVars2D, StoreDynVars3D
489        to individual fields
490        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
491    o store 3-D (in-situ) density in commom block (DYNVARS.h)
492     - save 1 rho computation.
493     - no longer modify T & S inland when using down_slope pkg.
494    o gad_som : allow to switch to SOM advection for T & S without corresponding
495      pickup files (using new S/R: MDS_CHECK4FILE).
496    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
497      (for useSingleCpuIO to work in multi-threaded)
498    o pkg/shelfice:
499     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
500       with SHELFICEtopoFile in data.shelfice
501     - move code for reading ice shelf topography and modifying hFacC into separate
502       subroutines of the shelfice package
503     - separate initialisation of "fixed" and "variable" variables
504     - kTopC is not (yet) replaced by kSurfC, although this is possible
505    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
506    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
507      and rename:
508      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
509      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
510    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
511    
512    checkpoint61c
513    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
514      to add mass source/sink of fluid in the interior (3-D generalisation
515      of oceanic real-fresh water flux).
516    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
517    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
518    o new pkg: down_slope
519      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
520      - presently, modify T & S inland (dwnslp_calc_rho.F).
521        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
522      - implementation for ocean in P-coords not tested.
523      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
524    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
525      (to facilitate conversion of oceanic pkg to p-coordinate).
526    o change FIND_RHO to FIND_RHO_2D :
527      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
528    o new pkg: cheapaml
529    
530    checkpoint61b
531    o exch2:
532      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
533      - no longer depend on the order sequence (N,S,E,W).
534      - 3rd exchange no longer needed (tested with 24 tiles).
535      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
536      - exch_UV_A-grid readily available (but not yet tested).
537      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
538      (both are no longer needed) in exch_uv: no effect in forward run; but
539       get truncation error differences with adjoint exch.
540    o exch2:
541     - change index-bounds storage (moved from target to local tile,
542       more intuitive this way) ; rename/remove some variables.
543     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
544    
545    checkpoint61a
546    o exch2/matlab-topology-generator:
547      fix bug in index bounds for N-S internal exchange (hard to tell if this
548      had any effect on the solution).
549    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
550      is exceeded
551    o testreport: modify syntax of awk, so that it works also with
552      awk, and not only with nawk and gawk
553    
554    checkpoint61
555    o autodiff
556      Change default for TAF usage by removing argument '-nonew_arg'
557      This changes TAF subroutine argument list (ordering of active var.)
558      Omission of this flag leads to incompatibility w.r.t. TAMC
559      To restore TAMC-compatibility, need following modifs:
560      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
561      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
562      Tested TAF version is 1.9.22
563      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
564    
565    checkpoint60
566    --->>> This is the last checkpoint for which generating the adjoint
567    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
568    --->>> by default.
569    --->>> Future checkpoints will ommit this flag by default.
570    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
571    o pkg/grdchk: Add gradient check to etan0 perturbations.
572    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
573    o pkg/autodiff: more flexibility in zeroadj.
574      model/src: modifying do_oceanic_phys.F accordingly.
575    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
576    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
577      special setup of gmredi for which the adjoint is stable
578      enough for parameter optimization.
579    o bridging the gap between eddy stress and GM.
580      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
581          along with a change in CPP option (now ALLOW_EDDYPSI).
582      -> when using GM w/ GM_AdvForm:
583          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
584          is applied either in the tracer Eq. or in momentum Eq.
585          depending on data.gmredi (intro. GM_InMomAsStress).
586      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
587      The key modifications are in model/src/taueddy_external_forcing.F
588      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
589    
590    checkpoint59r
591    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
592      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
593      fix option to read coriolis(@ cell-corner) from files with CS-grid.
594    o pkg/mnc: add some attributes to standard 1D-coordinate variables
595    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
596      mass points, when using mnc for output
597      - add runtime parameter (missing_value, missing_value_int) to override
598        default (which is the value of getcon('UNDEF'))
599    o pkg/mnc: prepare mnc for the actual use of missing values with the
600      diagnostics package: small fix in mnc_cw_readwrite.template and more
601      initialisation of never used fields
602      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
603      versions
604    o pkg/thsice/thsice_ini_vars.F added default initial values so that
605      thermodynamics sea ice solver does not blow up when some initial fields
606      are missing.
607    o move from external_forcing_surf.F to ini_forcing.F
608      the p-coord. hack consisting in using pLoad to set phi0surf ;
609      update output of tutorial_global_oce_in_p (affected @ truncation level).
610    o Freshen up a bit hs94.1x64x5, notably:
611      remove rotationPeriod and tRef=5*0. (adjoint only), and add
612      exactConserv=.TRUE.
613    o pkg/generic_advdiff:
614      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
615      applies to files where Temperature & Salinity 2nd Order moments are used.
616    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
617      this uses a dynamically allocated internal state data structure
618      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
619      and requires a fortran 90 compiler
620    
621    checkpoint59q
622    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
623       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
624    o Refresh tutorial_global_oce_biogeo, notably:
625      - change bathymetry (put back seamounts in ACC, use hFacs)
626      - change EOS (POLY3 --> JMD95Z)
627      - use Bryan-Lewis vertical diffusivity
628      - use multidimensional advection
629      - remove old virtual virtual in dic pkg, now done through ptracer pkg
630      - change a couple of parameters in dic pkg
631    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
632    o pkg/obcs: change default to OBCSfixTopo = .true.,
633      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
634      - replace "debugMode" with "debugLevel .GE. debLevB"
635    o implementation of TAF directives for gchem,cfc,dic
636    o remove "exp5" (replaced by tutorial_deep_convection).
637    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
638      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
639      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
640      --> changes results in exp4, seaice_obcs
641    o tutorial_deep_convection :
642      update the set-up and increase resolution and domain size ; start
643      from pseudo initial conditions = output at t=120mn in order to see
644      something happening when running testreport.
645    o pkg/seaice: add os7mp as an advection scheme
646                  add check for advection schemes
647                  add a flag for restoring T and S underneath sea ice
648    o pkg/my82: add netcdf-support and diagnostics
649    o thsice pkg:
650      - Now hsMax limits snow height by turning it into ice following
651        flooding scheme (and now conserving energy)
652      - Slight rewriting of the formula in thsice_calc_thick.F
653      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
654      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
655    
656    checkpoint59p
657    o gchem / dic / cfc :
658      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
659      - add new parameter files: "data.dic" & "data.cfc" ;
660      - various re-arrangement in initialisation & header file ;
661      - fix tutorial_global_oce_biogeo for multi-threaded test.
662    o pkg/dic: test for "pickup_dic" file when restarting ;
663      if no pickup-file, can restart with a re-initialised pH (same as it did
664      before) providing pickupStrictlyMatch is set to False.
665    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
666      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
667    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
668      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
669    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
670     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
671       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
672    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
673       scheme to use for vorticty-term ;
674     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
675       (with default selectVortScheme, return to original discretisation)
676     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
677    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
678    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
679      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
680      also fix diagnostics VISCAHW & VISCA4W.
681    
682    checkpoint59o
683    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
684    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
685      move a few statemens out the main loop into separate loops
686    o pkg/shelfice:
687      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
688        (kg/m^2/s), does not break tests, because in verification/isomip,
689        rhoConstFresh=rhoConst (by accident)
690      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
691      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
692        new file model/src/seawater.F, so that they are available for all pkgs.
693      - convert potential temperature into in-situ temperature. This changes the
694        isomip tests => update tests
695    o add a flag writePickupAtEnd (default=true) to be able to suppress
696      writing a pickup at the last timestep
697    o tools/mpack-1.6 :
698      - disable automake (not working) and autoconf (not needed).
699      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
700        also cleaner with much less compilation warnings.
701    o pkg/profiles:
702      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
703      (for "less than 32 characters name" compiler requirement)
704    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
705      conditions that have a different sampling frequency than S/T/U/V obcs
706    o pkg/diagnostics (stats-diags):
707      - fix global Min/Max in case 1 processor get only empty tiles
708    o genmake2: replace (4 times)
709         make genmake_tc_1.o >> genmake_warnings 2>&1
710      with
711         COMM="$CC $CFLAGS -c genmake_tc_1.c"
712         echo $COMM >> genmake_warnings
713         $COMM >> genmake_warnings 2>&1
714      to make genmake2 always see the value of CC as specified in the optfile.
715    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
716      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
717      - modify verification advect_cs test to test SOM-advection on CS-grid.
718    o pkg/ctrl:
719      - Rewrite of ctrl_map_ini_ecco.F,
720        introducing a generic routine (ctrl_map_ini_gen.F).
721      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
722    
723    checkpoint59n
724    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
725      number in dedicate array "hdiag":
726      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
727        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
728      - many small changes (integer format) for large number of diagnostics
729      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
730        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
731    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
732      usingSphericalGrid, this allows to define the rotated grid coordinates
733      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
734      geographical coordinates according to the inverse of the rotation defined
735      by the Euler angles, so that Coriolis parameter and online-interpolation by
736      exf works with the geographical coordinates on XC/YC/XG/YG.
737      Naturally, this feature does not work with all packages, so some
738      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
739      profiles), because there the coordinates are assumed to be regular
740      spherical grid coordinates.
741    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
742      - introduce isopycnal diffusion coefficient control.
743    o tools/adjoint_options:
744      - additional control vector components.
745    o pkg/mnc: have mnc create marginally meaning full coordinate variables
746      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
747    o pkg/mypackage:
748      - add example of read/write pickup for state-var ;
749      - add entry points to the main code for state-vars diags & write-pickup.
750    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
751      transitions for useExfYearlyFields
752      - add new subroutine that determines the file to read from for
753        use*YearlyFields = .TRUE. and .FALSE.
754      - add a verification experiment to global_with_exf that tests
755        useExfYearlyFields with USE_EXF_INTERPOLATION defined
756    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
757      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
758      subroutines (which could be generated from a template, because they are
759      almost identical), for now they are included in obcs_prescribe_read.F for
760      simplicity
761    o pkg/exf:
762      - add a little more diagnostic to exf_interp_read (in analogy to
763        mds_read_field, can be turned off with debugLevel < debugLevA=1)
764      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
765        ugly but fast by unrolling short inner loops, inserting a unroll=8
766        directive in routine lagran, and splitting a loop and making do while the
767        outermost loop (the latter requires the intoduction of index arrays)
768    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
769    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
770      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
771    o verification/seaice_obcs: updated for restart test and latest options
772    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
773      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
774      for now this is only available for the C-grid code and also within
775      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
776    
777    checkpoint59m
778    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
779      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
780    o gad_som : fix flux output (& diagnostics) to have same units as other  
781      advection scheme fluxes (was previously multiplied by deltaT).  
782    o added verification/seaice_obcs both to test seaice open boundaries
783      and to provide an example matlab scrpt for generating them
784    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
785    o pkg/salt_plume: clean up salt_plume_frac.F to
786      remove redundancy in PlumeMethod 1 and 4
787    o pkg/kpp: added saltplume diagnostics
788    o pkg/obcs and pkg/seaice:
789      - do not set uice and vice to zero when OB*icefile are unspecified
790      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
791      - moved seaice tracer obcs after call to seaice_growth
792    o pkg/salt_plume: added various options for salt plume depth
793      criterion and for vertical distribution of the salt
794    
795    checkpoint59l
796    o pkg/ptracers: new version of ptracers pickup:
797      read meta file and write only fields which are needed to restart.
798      ( same logic as main pickup file ; also using pickupStrictlyMatch )
799    o pkg/seaice:
800      - add timescale for melting due to warm mixed layer as a means of
801        setting SEAICE_availHeatFrac more conveniently
802      - add a CPP-flag/runtime parameter check for flooding algorithm
803      - reformulated availHeat in seaice_growth.F to be independent of AREA
804    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
805      unit changes
806    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
807    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
808      SX vector computer.
809    o pkg/seaice:
810      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
811        seaice forcing fields can now be read only through pkg/exf
812      - removed some unused halos
813    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
814    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
815      or U/VICE from U/VWIND before computing U/VSTRESS
816    
817    checkpoint59k
818    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
819      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
820    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
821      all experiments pass when compile with un-initialised var. checking option.
822    o added pkg/salt_plume
823    o script to test restart (for now, in MITgcm_contrib/jmc_script)
824    o pkg/seaice: new read/write pickup version.
825      read meta file and write only fields which are needed to restart.
826      ( same logic as main pickup file ; also using pickupStrictlyMatch )
827    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
828    o lab_sea.hb87: modify the domain & update output.hb87.txt :
829      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
830      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
831      process. Fixed here by closing the domain at the Northern boundary.
832    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
833    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
834      a set of consecutive levels in/from a 3-D array.
835    o pkg/ptracers:
836      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
837      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
838    
839    checkpoint59j
840    o in pkgs: dic, obcs, offline, rbcs:
841      standard way to compute coeff. for time interpolation between 2 time reccords
842      which retains full precision (& make results less dependent on compiler).
843      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
844    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
845      packages instead of reading ice cover and wind speed separately
846    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
847     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
848      to allow to compile customized code before the update)
849    o cleaning-up:
850      - fix CPP instruction syntax in pkg/obcs
851      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
852        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
853      - fix some threads issue in IO parts.
854    o pkg/dic:
855      - add tons of "_d 0" (--> much better testreports !)
856       and then update outputs of tutorial_global_oce_biogeo
857    o pkg/mom_fluxform:
858      add a special version of momentum advection intended to conserve momentum
859      next to a bathymetry step or a coastline edge. (default = off = #undef)
860    o new read/write pickup version:
861      - for now, only implemented for main (mdsio) pickup file.
862      - write out only what is needed to restart; merge pickup_nh , pickup_ph
863        and main pickup together.
864      - read meta file; read only what is needed to restart; stop if a field
865        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
866        if it make sense (even if the restart is not perfect).
867      - if no meta file, assume that pickup to read corresponds exactly to
868        a pickup that would currently be written.
869      - read pickup written in the old format (until checkpoint59i) if it
870        recognizes an old meta file (no field-list).
871      - add a meta file in exp. which starts from a pickup: 2 cases:
872        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
873         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
874        b) a meta file describing the content of the associated pickup file
875         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
876    o pkg/mdsio & pkg/rw:
877      - new routine to read a meta file ; new set of routine to read
878        Multiple-fields file (with meta file).
879    o added open boundary conditions capability for seaice
880        HSNOW, HSALT, UICE, and VICE
881    
882    checkpoint59i
883    o adjoint:
884      * fix multiDimAdvection adjoint
885        (partial recomputation problem by TAF for fVerT(:,:,kDown)
886        and comlev1 size definition (maxpass vs. max. number of tracers)
887      * verification/global_ocean.90x45x15 adjoint now tests
888        NLFS and multiDimAdvection using DST3 (=30)
889      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
890    o pkg/kpp: add "_d 0" to real constant (if missing);
891      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
892      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
893    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
894      for internal parameters related to restart process (formerly from PARAMS.h)
895      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
896    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
897      as argument. (only atm2d & obcs write_pickup have not yet been updated)
898    o pkg/monitor:
899      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
900      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
901      - account for deep Atmosphere factor and density factor (anelastic)
902    o added open boundary conditions capability for seaice HEFF and AREA
903    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
904      thermodynamics
905      - requires a little reorganization, which affects the testreport results
906        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
907        so that now the conservative form is tested
908      - add a few comments
909    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
910    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
911    o add new diagnostics to seaice: advective, diffusive fluxes (only for
912      multidim-advection, for scheme 2 they are not filled) and transports,
913      thermodynamic growth rates
914    o change units of EmPmR (inside the code, + within coupling interface)
915      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
916      Affects results @ truncation level (cg2d match) and update output of
917       experiments: lab_sea(6), global_ocean.90x40x15(10),
918      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
919      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
920      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
921      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
922    
923    checkpoint59h
924    o pkg/exf:
925      - improve vectorization by moving if-statement out of loops in
926        exf_mapfields, exf_radiation
927      - exf_bulkformulae.F: introduce 2D fields and vectorize code
928    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
929    o testreport:
930      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
931        monitor & update offline_exf_seaice exp. output.
932      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
933    o pkg/seaice:
934      - bug fix in the evp solver: boundary conditions were affected be
935        masking of zMax/zMin (changes results)
936      - minor bug fix in boundary conditions in seaice_calc_strainrates
937        (changes results for no_slip)
938      - seaice_lsr.F: make interpolation of eta dependent on boundaries
939      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
940      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
941        stress formulation and no-slip boundary conditions
942    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
943      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
944    o pkg/seaice: a first HSALT time stepping equation has been checked in
945    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
946      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
947      without requiring DO-IF statements
948    o pkg/thsice:
949      use continuous power-law function for partition of energy between lateral
950      melting/freezing and thinning/thickening ; old code using step function
951      still available with #undef THSICE_FRACEN_POWERLAW
952      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
953    o testreport: change AD testing : check against results/output_adm.txt
954      using same scripts as for forward test.
955    
956    checkpoint59g
957    o adjoint testing: in preparation for changing testreport:
958      - output format: cost and grad written on separated lines
959      - ad output results in directory "results" (instead of "results_ad")
960    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
961    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
962    o pkg/ecco: allow user defined cost function contributions
963    o testreport:
964      Allow to choose (per experiment) the list of tested output variables
965       and the main variable (used to issue a pass/FAIL ) ;
966      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
967      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
968      Also modify printing of summary:
969       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
970       b) echo the list of tested variables in the individual summary.txt of
971          each experiment.
972    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
973      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
974      (but still depend on the tile decompostion of the domain).
975    o pkg/seaice: change a discretization detail to make the B-grid code
976      "more symmetric". This change is likely to remove all "ridges/leads" that
977      where quasi-aligned with the grid in B-grid solutions. It may also be
978      the solution to the stress coupling issues with the B-grid.
979    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
980      remove .cvsignore from input dir. (since testreport no longer run here).
981    o pkg/thsice:
982     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
983     - fix reshaping of sea-ice just after advection:
984       melt all the ice only if ice-volume is too small.
985     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
986       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
987     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
988    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
989      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
990    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
991      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
992      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
993      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
994      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
995      -> update output.txt
996    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
997     this affects truncation error: -> update output.txt of exp:
998      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
999      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
1000    
1001    checkpoint59f
1002    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
1003    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
1004      a bounded range (in forward mode)
1005    o pkg/ecco, ctrl, autodiff and mom_common:
1006     internal parameter controls, completements of implementations
1007    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
1008    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
1009      (not seem any difference in testing results).
1010    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
1011       at face corners.
1012    o pkg/generic_advdiff:
1013     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
1014      loop range indices for computing vertical advection tendency
1015      and do the calculation in the interior only (no overlap) ;
1016      for now, only implemented for SOM advection (to save CPU time).
1017     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
1018    o exch2 adjoint
1019      First set of changes:
1020      - add exch2 hand-written adjoint templates
1021      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
1022        This will require cleanup in pkg/autodiff/*.F
1023        (changed routines currently kept separate in verif. code/)
1024      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
1025        that used to hide exch2 or cubed-sphere specific code
1026        (commented via 'cph-exch2')
1027    o pkg/seaice
1028      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
1029    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
1030       output of global_ocean.cs32x15.thsice .
1031    
1032    checkpoint59e
1033    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
1034      for B-grid vector (not yet tested) and C-grid vector (<- only used
1035      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
1036    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
1037      (#ifdef ALLOW_SALT_PLUME)
1038    o gather_2d/scatter_2d: removed halo regions
1039    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
1040      scheme and the corresponding test case (under front_relax dir). For now,
1041      only available with Skew-flux form and not yet tested in realistic set-up.
1042      adjoint: store directives updated, but gradient checks deteriorated,
1043      so maybe GM/Redi adjoint is now broken.
1044    o seaice adjoint
1045      * add AREA, HEFF, HSNOW as control variable
1046        (should not change lab_sea results)
1047      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
1048    o pkg/seaice:
1049      * added computation of saltFlux in seaice_growth;
1050        For time being, sea ice salinity is assumed constant
1051        contribution of snow flooding to freshening of sea ice is neglected.
1052        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
1053        defaults to 0.0 in order to maintain backward compatibility.
1054        Typical values for SEAICE_salinity are 4 to 10 g/kg.
1055      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
1056      * added SEAICE_availHeatFrac, which specifies fraction of surface level
1057        heat content used to melt or grow ice
1058      * commented out cap of HICE: it helps keep ice thinner
1059      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
1060      * applied OBCS T/S mask to HEFFM sea ice mask
1061    
1062    checkpoint59d
1063    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
1064     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
1065     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
1066    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
1067     and change default value of parameter "GM_Small_Number";
1068     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
1069       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
1070       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
1071    o pkg/ecco: cost function when applying pkg/smooth to controls
1072    o pkg/ctrl: add forcingPrecond run time parameter
1073    o pkg/seaice:
1074     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
1075     - fix bug in metric terms of u-equation in LSR solver (implicit part),
1076       changes verification/lab_sea
1077     - rearrange implicit part of u-equation in LSR solver to make it easier to
1078       read, understand, and debug. This causes changes at the truncation level.
1079     - fix (serious) bug in the boundary conditions (sign error in the implicit
1080       part) of the LSR solver. Changes all LSR results.
1081     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1082       is initilized with small values - does not change lab_sea results.
1083     - added HsnowFile initialization capability
1084    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1085     initialization of pkg/smooth and application to control vector
1086    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
1087    o dependencies: pkg/profiles requires pkg/cal
1088    o pkg/profiles:
1089     - added option ALLOW_PROFILES_GENERICGRID
1090         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1091         that interpolation information (grid points and coefficients) is provided
1092         within the netcdf input files.
1093         -> sample matlab scripts can be found in MITgcm_contrib/gael
1094         that allow you to prepare netcdf input files.
1095     - also modified: cleaner include statements, cleaner error print statements,
1096       cleaner stops when error, and more tests of the netcdf input files consistency.
1097    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1098    o pkg/seaice:
1099     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1100       requires a new routine: seaice_diagnostics_fill.F
1101     - make sure that seaice does not move if not forced (pressure replacement
1102       method, Hibler and Ip, 1995), changes results
1103     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1104     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1105       It is turned off by default (=-1.), because it changes the results.
1106     - make it possible to read AREA from a file, too.
1107    
1108    checkpoint59c
1109    o add S/R and diagnostics for oceanic mixed-layer depth
1110    o move GMRedi call after all vertical mixing schemes (including KPP)
1111    o pkg/thsice:
1112     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1113      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1114    o pkg/obcs:
1115     - bug fix for balance code
1116    o pkg/seaice:
1117      - allow values of SEAICE_elasticParm > 1
1118      - add new parameter SEAICE_evpTauRelax as an alternative
1119        to SEAICE_elasticParm
1120      - make lsr boundary conditions free slip (by default), changes result
1121      - add code for no slip boundary conditions for lsr
1122      - set minimum of zeta to zero (and not 4e8) (changes results)
1123      - add a cap on AREA after advecting AREA if seaice_growth is not called
1124    o change calculation of Visbeck K:
1125      - no longer depend on tapering scheme; instead, compute slope (limited
1126        by GM_maxSlope). this is equivalent to what was comuted before with
1127        clipping or linear tappering.
1128      - fix vertical averaging (wrong by 1/2 level)
1129      - leave the old version (but will not be maintained) within
1130        #ifdef OLD_VISBECK_CALC / #endif
1131      - update output of exp. ideal_2D_oce
1132    o change error catch in calc_r_star to improve vectorization
1133    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1134      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1135    o adjoint:
1136      Re-organized adjoint checkpointing according to Matt Mazloff
1137      (but with modifs/completions/cleanups)
1138      Storing is now bundled into large arrays to optimized I/O
1139      (and second step in cleanup of the_main_loop)
1140    
1141    checkpoint59b
1142    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1143      - export/import (between ocean & coupler) fields needed for ocean DIC.
1144    o pkg/seaice:
1145      - get rid of three more exchanges seaice_calc_viscosities (required
1146        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1147      - bug fix in seaice_ocean_stress (update of lab_sea required)
1148      - reduce loop boundaries to necessary minimum also in seaice_evp
1149      - go back to the old way of computing deltaC/Z as the adjoint likes that
1150        better
1151    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1152      passive tracer to an Age Tracer) + update output.txt
1153    o pkg/exf:
1154      - implement A-grid / C-grid selection for wind-stress input files.
1155      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1156      for now, in exf_bulk_largeyeager04.F only :
1157      - change implementation for case where windspeed + 2. components wind-stress
1158        are read-in. AND use rhoConstFresh to convert evap.
1159    o pkg/seaice:
1160      - use correct EXCH_UV for wind-forcing (on A-grid).
1161      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1162        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1163    o pkg/exf:
1164      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1165      EXF_INTERPOLATION:
1166      - merge global_with_exf/code version of exf_interp_read.F
1167        to the main code ;
1168      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1169        reading the file ; Important: This options needs to be defined to recover
1170        previous code.
1171        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1172      - no longer loose real*8 precision along the way when using exf_iprec=64.
1173    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1174      - change discretisation of evp-solver in order to avoid another exchange
1175        (changes lab_sea) and clean up a little
1176      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1177        help the adjoint (this also changes the results slightly)
1178      - add a few "_d 0" where they had been missing in seaice_evp.F
1179      - cleaning up: remove unused seaice_calc_rhs.F
1180    o pkg/exf: some cleaning-up:
1181      - change various "constants" into runtime parameters
1182      - cleaned-up Large&Yeager04 routine which should eventually
1183        replace exf_bulkformulae.F (changed names of S/R and CPP)
1184        and merged various ALLOW_ATM_WIND options
1185     only used with thsice pkg (in thsice_get_exf.F):
1186      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1187        which are used when useStabilityFct_overIce=TRUE (= the default)
1188      - change default values of ice & snow emissivity and scale downward LW
1189        by ice & snow emissivity.
1190    o pkg/thsice:
1191     fix few little problems, in thsice_calc_thickn.F:
1192      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1193      - melt only laterally if hIce < hThinIce (as the comments say)
1194      and in thsice_extend.F:
1195      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1196      - start to form ice as soon as the minimum ice-volume is reachable.
1197     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1198      and cpl_aim+ocn
1199    o pkg/kpp
1200     - move computation of surface related input fields to KPP into a new
1201       subroutine kpp_forcing_surf.F
1202     - remove wrong (within bi,bj loops) EXCH calls.
1203     - little cleaning (add argument myThid in last position, cvs header ...)
1204     - for now, fix conservation problem by exchanging KPPviscAz (may not
1205       be the best fix)
1206    o pkg/seaice
1207     - check for inconsistent evp parameter/cpp-flag combination
1208     - remove leftover errIO flat for obsolete name list error handling
1209    o OpenAD
1210     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1211    
1212    checkpoint59a
1213    o pkg/seaice: some parameter clarifications and a little bit of clean up
1214    o pkg/thsice: rename run-time parameters:
1215       himin       -> hIceMin
1216       himin0      -> hThinIce
1217       hihig       -> hThickIce
1218       i0          -> i0swFrac
1219       transCoef   -> bMeltCoef
1220       frac_energy -> fracMelting
1221      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1222       with default values (for now) that do not change the results.
1223      remove old version of thsice vars advection in pkg/seaice.
1224    o in FFIELDS.h:
1225      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1226      - make pLoad & sIceLoad always available (but still only used if
1227         ATMOSPHERIC_LOADING is #define).
1228    o pkg/kpp: replaced _KPP_RL with _RL
1229    o bug fixes for vertical diffusivity computations when both KPP and
1230        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1231        are no longer updating the vertical diffusivity array
1232        (passed as argument) but are (re-) setting those arrays.
1233    o pkg/seaice: fix bug in evp solver, while doing that
1234      - change (improve?) discretization of stress computations for both
1235        cgrid-lsr and evp solver
1236      - add a new routine to compute strain rates
1237      - the above changes lab_sea results
1238      - add no slip conditions for evp solver (off by default), lsr-version
1239        may follow
1240      - fix exchange for shear at Z-points (does not change lab_sea)
1241      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1242        (to force the user to pick a time step since there is not "safe" way
1243        of choosing it)
1244      - add principal stress diagnostics
1245      - rearrange fields for evp a little to avoid having to call a: too many
1246        exchanges and b: exchanges for stress trensor components which we do
1247        not have.
1248      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1249        of evp, complete rewrite for lsr case (latter is does not yet work
1250        in all cases)
1251    o pkg/kpp: add code to have mixing in shelf ice caverns
1252      - add myThid to all kpp routines (long overdue)
1253    
1254    checkpoint59
1255    o pkg/exf:
1256      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1257        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1258      - move exf header files from lower_case.h to UPPER_CASE.h ;
1259        add missing cvs Header & Name
1260      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1261      - add namelist param. selectStressGridPosition, exf_monFreq
1262      - retire many _CLIM routines, and remove data.exf_clim
1263        + params moved to data.exf
1264        + climsst, climsss now handled by exf_set_gen, i.e.
1265          climss?period=0 refers to constant field,
1266          climss?period=-12 to monthly forcing
1267      - split up namelists in data.exf
1268    o pkg/seaice:
1269      - remove seaice_exch and seaice_exch_uv
1270      - remove superfluous exchange of theta
1271      - add myThid to seaice_budget_ocean/ice
1272      - add new interface for atmospheric wind forcing (C-grid only)
1273        + new routine
1274        + two new field (taux, tauy for stress over ice)
1275        + removed one global field (DAIRN) for C-grid case only
1276    o pkg/thsise
1277      - 2nd set of modifs for thsice adjoint in conjunction with exf
1278    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1279    
1280    checkpoint58y_post
1281    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1282      vertical diffusivity, similar to that in MOM4; turned on using
1283      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1284      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1285    o Added capability for 3D specification of background vertical diffusion
1286      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1287      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1288      "data" file that contains the 3D vertical diffusivity coefficients.
1289    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1290      - add code within pkg thsice to advect & diffuse sea-ice fields
1291      similar to (and will replace) what has been added in  seaice_advdiff.F,
1292      but: - conserving Mass, Heat & Salt.
1293           - better when using non-linear advection scheme (not yet fully tested)
1294           - can also be used in atmospheric set-up (for now, only the diffusion).
1295    
1296    checkpoint58x_post
1297    o IO option for global-file compact format:
1298      - add options when generating topology (utils/exch2/matlab-topology-generator)
1299      - add I/O capability (pkg/mdsio).
1300      - adapt utils/matlab/rdmds.m to read this format.
1301      for now long-line format not yet supported by pkg/mdsio (& exch2).
1302    o shelfice: add a few diagnostics
1303    
1304    checkpoint58w_post
1305  o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:  o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1306    rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref    rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
