4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice/autodiff:
8     - modify computation and store zetaC/Z in seaice_evp for TAF
9     - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)
10     - change seaice_calc_viscosities/strainraties for better
11       vectorization after AD by TAF
12     - rearrange common blocks in SEAICE.h once again for easier dumps of
13       adjoint output, adjust adcommon.h and g_common.h
14     - change flux form of default advection scheme for better vectorization
15       of adjoint code
16     - modify lab_sea/input.lsr to test the flux form of default advection
17       scheme
18    o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level
19      transition in checkpoint61r)
20    
21    checkpoint61x
22    o adjoint: adding two new verification experiments
23      * tutorial_global_biogeo: an online dic sensitivity experiment
24        (work with G. Forget)
25      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
26        (an update of the Dutkiewicz et al., 2006 paper)
27      Both use the same CO2FLUX cost function, but different controls
28      Gradient checks look good, but some recomp. could still be traightened out
29      Should add xx_dic control variable to test at some point
30    o model/src:
31      add run-time parameters to check and/or mask initial Temp & Salt
32    o pkg/ptracers:
33      apply zonal filter (if used) to all passive tracers
34    
35    checkpoint61w
36    o adjoint:
37      * update and finish work on adjoint of dic package (G. Forget)
38      * start adjoint of offline package
39      * bug fix for cube-sphere TLM code (active_file_g.F)
40    o tutorial_global_oce_optim:
41      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
42      and add SIZE.h_mpi for MPI testing
43    o pkg autodiff
44     - fix bug in autodiff_restore
45     - make genmake2 remove comments and empty lines from ad_input_code.f in
46       order to reduce file size (new script file remove_comments_sed)
47    o allows to specify vertical profile of vertical viscosity (viscArNr)
48    o pkg autodiff
49      autodiff_ini_model_io: comment out writing of grid information to netcdf
50      files, because at this time the grid fields are a bunch of zeros
51      (this is analogous to ini_mnc_vars.F)
52    o pkg seaice/autodiff:
53     left-over from removing the 3-time-level fields:
54     - small rearrangement of common blocks (SEAICE.h)
55     - fix field declaration in order to get meaningful output in
56       adseaice.*.nc (adcommon.h)
57    o pkg obcs:
58     - go through NH code only if nonHydrostatic=T
59     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
60     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
61       => Update output of experiment seaice_obcs
62     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
63     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
64     - fix restart for useOBCSprescribe + useEXF
65    o pkg ctrl
66     - make obcs as control parameter work also with useSingleCPUio
67     - replace a few sny and snx by Ny and Nx to be consistent with
68       ctrl_set_globfld_x/yz.F
69    o pkg seaice
70     - re-introduce global field frWtrAtm for the case of
71       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
72     - catch the case of an empty filename in seaice_cost_init_fixed.F
73    o pkg ecco:
74     - small bug fixes in the_main_loop
75      . fix order of monitor arguments
76      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
77      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
78        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
79     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
80       imbalance diagnostics for wmean_h/sflux = 0
81     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
82     - catch the case of empty filenames in ecco_cost_init_fixed.F
83       and ecco_readparms.F
84     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
85       to make this statement meaningfull in ecco_cost_weights.F
86    o pkg zonal_filt:
87      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
88      - when using rStar, filter uVel*hFacW instead of uVel
89       (tested without topography: fix a Pb of growing instability with NLFS)
90    o pkg/aim/thsice:
91     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
92      (works as SST restoring)
93    o pkg/thsice:
94     -add specific parameter for salt restoring in slab mixed-layer
95       (by default equal to the temperature restoring)
96    
97    checkpoint61v
98    o pkg/kpp:
99     -add double diffusive contributions as a hack, turned off by default
100      for now, and the code can be excluded with a CPP-flag
101      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
102     -add a verification experiments to "vermix" to test this code
103    o pkg/mom_common:
104      Move computation of length scales to mom_init_fixed.F (avoid recomputation
105      at each time-steps*levels).
106    o pkg/layers:
107      Created a new package for computing volume fluxes in temperature or
108      [not yet implemented] density layers, e.g. for calculating residual
109      overturning circulations.
110    o pkg/diagnostics:
111      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
112    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
113    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
114      To avoid mixing type (RS/RL) of input/output array argument,
115      replace single mixed-type array with a pair from each type (RS/RL).
116    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
117      is now implemented for all pkgs (previously only done for the main pickup)
118    
119    checkpoint61u
120    o pkg/obcs:
121      - change OB?eta from _RS to _RL and put them into a separate commen block
122      - add code to read OB?eta from a file via obcs_prescribe_read: the code
123        compiles and does not destroy any other experiments, the data is read
124        properly, but the code is not tested in actual applications
125    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
126      create a meaningful unit attribute for the time coordinate variable
127    o pkg/ebm: add plenty of missing "_d 0" ;
128       update results of experiment global_ocean_ebm (fwd + adjoint tests)
129      Notes: several pieces of code only works for (very) specific set up
130       (domain size, lat range, etc ...); should be documented & stop if one
131       of those assumptions is not meet.
132    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
133       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
134          and offline_exf_seaice (seaicetd + adjoint).
135    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
136       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
137        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
138    o few changes to pass when compiling with strick checking of arguments
139       across S/R (allow to find few bugs in S/R calls).
140    o pkg/seaice:
141     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
142       2d-fields, for slightly better performance
143    
144    checkpoint61t
145    o pkg/seaice:
146     - remove unused variables in seaice_evp
147     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
148    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
149       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
150       each processor opens a different file (a fix from Matt).
151    o cg2d:
152       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
153       this reduces number of EXCH calls by 2 when using exch2.
154       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
155       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
156    o pkg/thsice:
157       add code for Near Infra-Red albedo (from Jeff)
158       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
159    o ini_model_io:
160       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
161       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
162       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
163    
164    checkpoint61s
165    o pkg/exch2 (exch2_rxN_cube*):
166       remove last BARRIER (no need to synchronise after getting data from shared
167       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
168    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
169      and generate new output (for the 2 tests) using default rotationPeriod.
170    o pkg/exch2:
171      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
172        (was already the case with AUTODIFF_EXCH2 defined)
173      - add bj in exch2 arrays and S/R.
174      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
175        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
176    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
177      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
178        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
179      - verification experiment natl_box.longstep
180    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
181      allow different versions of ifort (8 or 9) and different versions
182       of mpi (mpich or mpich2) to be used with the same optfile.
183      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
184       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
185    o pkg/seaice:
186      fix previous modif (3-level field removed) for old-pickup reading
187    
188    checkpoint61r
189    o pkg/seaice:
190     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
191      1. introduce fields for time step (N-1)
192      2. do not use levels 2 and 3 anymore (but keep them)
193      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
194         includes changes to pkg/thsice/thsice_get_velocity.F,
195         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
196         pkg/obcs/obcs_apply_uvice.F.
197     - completely remove code for leap-frog time stepping for second order
198       advection
199     - adjusted adjoint accordingly;
200       gradient checks have improved by an order of magnitude!
201    
202    checkpoint61q
203    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
204     - the boundary conditions along open boundaries are unclear, because the
205       associated masks are set to zero and are thus treated as closed when
206       applying the slip-boundary conditions.
207     - move initialisation of grid variables from seaice_init_varia to _fixed
208    o adding doc/diags_changes.txt
209    o model/src:
210      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
211       to avoid "_diags" naming if no relation to pkg/diagnostics.
212      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
213       file and only call PLOT_FIELD_XYZ if debugMode=T.
214      remove few PLOT_FIELD_XY calls outside initialisation.
215      remove few unnecessary BARRIER.
216    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
217      of salt_plume package in Southern Ocean
218    o pkg/thsice:
219     - fix hOceMxL in overlap (needed for sea-ice advection);
220       update output of experiment global_ocean.cs32x15.icedyn.
221    o pkg/seaice:
222     - make the (placeholder-)tracer IceAge a little more meaningful
223      by avoiding ridging of age due to convergent ice flow
224     - add diagnostics for surface temperature, atmospheric and oceanic
225       heat flux, and atmospheric and oceanic ice growth
226    
227    checkpoint61p
228    o eesupp (global_max & global_sum):
229     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
230     - remove starting & endding barrier (no longer needed)
231    o pkg/mdsio, writelocal:
232       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
233       (remove the STOP): uses shared buffer IO to store data from all threads
234       and then let master-thread write nThreads tiles.
235    o pkg/mdsio (read/write field):
236     - tiled IO done in 1 piece (all levels at a time);
237     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
238     - multi-threaded: allow to read/write local (non-shared) array
239       (was already working with singleCpuIO ; now works also without);
240       => no longer needs barrier call after reading a file (added inside
241       mds_read/write field).
242     - move barrier calls outside gather/scatter_2d to mds_read/write_field
243    o pkg/obcs/exf
244      - exf_getffieldrec.F: add a few ". _d 0" and
245                            add code to catch the case fldperiod = 0.  
246      - obcs_precribe_read.F: change if statements so that they match
247                              the variable type (_RL)
248      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
249        exf_iprec) as part of namelist EXF_NML_01
250    o pkg/mdsio:
251      - read/write tiled (local) files: read/write 1-level tile chunk at a time
252        (instead of segment of length sNx); expected to speed up tiled IO.
253    o pkg/exch2:
254      - take buffer copy from/to array out of S/R exch2_send/recv into new
255        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
256        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
257      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
258      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
259        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
260        including Topology header file (and common blocks).
261      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
262        remove 2nd exch call in exch2_s3d_rx (no longer needed).
263      - document S/R arg. list (+ update some comments)
264    o pkg/seaice:
265      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
266        temperature and humidity over sea ice based on climatological values.
267      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
268        of LSR (this change is expected to change the results slightly because now
269        it uses slightly difference moduli from the second last LSR solution, but
270        that is more consistent with the stress computations; this part of the code
271        is not tested in the verification experiments)
272      - fix diagnostics for flux of ice in case of B-grid
273      - turn strain rates eij and press into global fields within global
274        common block in SEAICE.h for more straighforward diagnostics
275      - fix diagnostics for principal stress components, press, zeta, eta
276        to give something meaning full
277    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
278      new output (all 4 tests) using default rotationPeriod.
279    o pkg KPP:
280      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
281      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
282        and normal grid from 1 to Nr)
283    o Fix computations of L4rdt in mom_calc_visc.F
284    o eesupp:
285      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
286      should be called before a "stop" if we know that all process are going
287      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
288    
289    checkpoint61o
290    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
291    o model/src/ini_curvilinear_grid.F:
292       compute angleSin/CosC when they are not read from a file
293    o pkg/seaice:
294       add pseudo time stepping for LSOR
295    o pkg/exch2:
296       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
297    o pkg/seaice:
298       Adding separate sea ice albedo, drag coefficients, and HO in Southern
299       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
300    o SingleCpuIO:
301       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
302    o pkg/seaice:
303       put exchanged variable in (local) common block for MPI+Multi-Threads
304       to work (necessary with exch1, and for now with exch2 too).
305    o verification: to get more experiments tested with mpi, mth and mpi+mth,
306      change tiling of:
307       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
308       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
309      update output of exp:
310       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
311       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
312      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
313                       (note: output.txt generated on faulks using only 1 tile)
314    o eesupp & mdsio (SingleCpuIO):
315     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
316       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
317       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
318     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
319     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
320       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
321    o pkg/exch2:
322     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
323       read parameter file "data.exch2" if it exists; otherwise try default regular
324       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
325     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
326       with new code (not to be used, just as a backup solution).
327     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
328       in utils/exch2/input.
329    
330    checkpoint61n
331    o eesupp & mdsio (SingleCpuIO):
332      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
333        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
334        receive real*4 array (instead of real*8) to read/write 32.bit files.
335        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
336         and remove new mapping S/R)
337    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
338      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
339        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
340        when using exch2. Add S/R to map global io-buffer to global model array.
341      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
342    
343    checkpoint61m
344    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
345      and add 3 other S/R for other types (R4,R8,RS).
346      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
347    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
348     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
349     - reduce number of macro definitions (keep only those which are used);
350       can always call directly the corrresponding S/R if needed.
351     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
352       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
353     Fixed wrong type of arg in:

355       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
356     To fix: global_sum of var in common block is wrong (multi-threaded) in:
357       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
358     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
359    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
360      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
361    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
362    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
363      edges are closed (zero depth); might happen with "blank tiles";
364      for now, disabled if using OBCS.
365    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
366      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
367    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
368      to reduce length of 1.D array print in STDOUT.
369    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
370      + use 48 tiles (16x8): this will allow to test "blank tiles".
371    o start to test MPI + multi-threaded (change testreport to skip tests
372      where number of tiles do not match).
373    o genmake2: add option "-omp" to turn on Open-MP ;
374      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
375    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
376      and keep the original tile numbering. Note: compatible with old
377      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
378    
379    checkpoint61l
380    o Overlaps had been forgotten in calculating ijk keys : fixed
381    o fix cyrus makedepend for gcc 4.4
382    o experiment fizhi-cs-aqualev20:
383      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
384      and generate new output. Note: new output is much closer to the old
385      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
386      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
387    o pkg/fizhi:
388     - change to avoid indices going deliberately over array-bounds
389     - remove unnecessary MPI stuff
390     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
391     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
392       does not go over array-bounds and therefore returns reliable output.
393     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
394       this S/R has 4 output arguments, which are used inside "get_alarm";
395       when it is called with the same variable "ndum" in place of several
396       output arguments, this produces weird side effect inside "get_alarm"
397      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
398       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
399       address) and produces error.
400    o tools/gemake2: (March 27-29 2009)
401      with option "-mpi": link *_mpi files from "MODS" dir (this is what
402      testreport does).
403    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
404    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
405       update lab_sea.lsr & lab_sea.salt_plume results
406    o pkg/seaice:
407      Major overhaul of the LSOR solver: change discretization from original
408      finite differences to finite volume. The old routine is still in the
409      file seaice_lsr.F and can be turned on with the CPP-flag
410      SEAICE_OLD_AND_BAD_DISCRETIZATION
411      Along with this change, the discretization of the strain rates is changed.
412      The same flag turns on the old discretization in seaice_calc_strainrates.F
413      All verification experiments with seaice are affected (except for
414      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
415      results by setting the above flag.
416      Further changes involve changes in defaults:
417      - ALLOW_FLOODING is defined and turned on by default
418      - SEAICEadvSnow = .true. is now the default
419      - SEAICEadvSalt = .true. is now the default
420      - SEAICEadvAge  = .true. is now the default
421      - SEAICE_clipVelocities  = .false. is now the default
422                                         (as per J. Zhang's recommendation)
423      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
424        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
425      - seaice_growth: replace computation of UG by a simple copy from wspeed
426    
427    checkpoint61k
428    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
429      seaice_lsr: fixed a few metric terms,
430                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
431                  add more debugging diagnostics
432      seaice_evp: removed superfluous many metric terms of FV discretization
433                  of stress divergence
434                  affects lab_sea, lab_sea.hb87
435      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
436                  of stress divergence for non-evp solver
437                  (this part is not tested anywhere)
438      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
439                  they were effectively only half slip
440                  affects lab_sea.hb87
441      updated all relevant verification experiments (except lab_sea//output_adm.txt
442        which was left over, but fails at level 7 & 6)
443    
444    checkpoint61j
445    o pkg/seaice: turn a few hard wired parameters into run time parameters
446    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
447      time in seconds as promised by the usints in seaice_monitor and exf_monitor
448    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
449      that are not cubed-sphere grids
450    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
451    o pkg/ctrl:
452      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
453    o non-hydrostatic (calc_gw.F):
454      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
455      update output of exp. global_ocean.cs32x15.viscA4
456    o remove backward compatibility for thetaMin,phiMin
457      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
458    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
459      interpolated wind field not only for curvilineargrid=.true., but also
460      for a rotated grid (rotateGrid=.true.)
461    o pkg/exf: add capability to bypass interpolation for runoff
462      by setting yet another CPP-flag
463    o eesupp/src, B-grid exchange:
464      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
465    o autodiff
466      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
467      allows to switch to single-prec common blocks;
468      corresponding switch occurs in tamc.h, integer isbyte
469      TAF store directivs "byte" and "kind" seem equivalent;
470      Most tamc.h have been updated correspondingly.
471    
472    checkpoint61i
473    o autodiff:
474      fix autodiff_sore/_restore indices for obcs
475      (spotted by I. Hoteit, M. Mazloff)
476    o pkg/autodiff, pkg/ctrl:
477      Add flag to reduce all tapelev I/O to single-prec.
478      In data.ctrl set
479        doSinglePrecTapelev = .TRUE.
480    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
481      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
482    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
483      real fresh water flux (not yet)
484    o pkg/mdsio & rw:
485     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
486     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
487    o pkg/flt:
488     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
489       init_fixed & ini_varia.
490     - clean-up & simplify linear interpolation S/R:
491       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
492     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
493     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
494     - add vert. coordinate & horiz. indices to output files.
495     - change vertical position in initial condition, from index to depth [m].
496     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
497       (easier to get to a curvilinear grid) ; delX,delY no longer used.
498    o pkg/ggl90: a few modifications:
499     - fix bottom boundary condition, and interpolation of KappaE
500       near top and bottom
501     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
502     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
503     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
504    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
505      (maintain temporary backward compatibility, until next checkpoint)
506    
507    checkpoint61h
508    o pkg/diagnostics with "periodic averaging diagnostics":
509      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
510    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
511    o pkg/obcs: fix loop ranges for balancing code
512    o pkg/flt:
513     - improve criteria for finding which tile owns a float.
514     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
515    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
516      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
517      with ocean biogeo)
518    o pkg/flt:
519     - do some cleaning and fix the restart ;
520     - add output.txt in flt_example/results to get this pkg tested.
521    o genmake2: add an EXTENDED_SRC option and flag.
522       for now, cannot be turned on on command line (only through genmake_local)
523    o pkg/mdsio: read/write vector:
524     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
525     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
526       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
527     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
528      (drop to 4 digits matching for grad). But this test does not look very
529      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
530    
531    checkpoint61g
532    o pkg/flt:
533      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
534       + make OPTIONS file more standard.
535      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
536      - fix _BYTESWAPIO CPP-Flag
537      - standard reading of file-parameter "data.flt"
538      - fix argument list of S/R FLT_RESTART
539      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
540    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
541    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
542      a still unfixed compiler/optimization bug
543    
544    checkpoint61f
545    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
546      update results of global_ocean.cs32x15.icedyn test.
547    o move getcon.F from model/src to pkg/fizhi.
548    o pkg/exf: add parameter for extrapolation of temp up to the surface
549       and option to prevent negative evap (in bulk_largeyeager04 only).
550    o Prather Advection scheme: fix tracer conservation for divergent flow
551      (e.g., when using NonLin Free-Surface).
552    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
553    o gmredi (Visbeck-variable-K):
554     - add more parameters to Visbeck-variable-K.
555     - use a 5 points average for dSigmaR in Visbeck-K calculation
556       (more "homogenous": same stencil and same weights as in dSigmaH)
557     - update output of ideal_2D_oce experiment.
558    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
559      (#undef REAL4_IS_SLOW)
560     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
561       coordinate variable
562     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
563       (surface forcing fields), removes some of the functionality
564     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
565     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
566       probably not all: copy _RS surface flux fields to RL field before
567       calling DIAGNOSTICS_FILL
568     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
569       real*4 (CALL EXCH_*_RS) versions.
570     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
571       (generate new output).
572    
573    checkpoint61e
574    o gmredi (Visbeck-variable-K):
575      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
576      - change computation of Visbeck-K where Slope > Smax :        
577        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
578        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
579    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
580      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
581    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
582    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
583      does not become too large (to avoid precision problems in implicit-diffusion
584      solver); update ideal_2D_oce output.
585    o pkg ggl90:
586      - in ggl90_cal.F: compute only one set of visc/diff, used to
587        step forward TKE/T/S/momentum
588      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
589        have Prandlt =1)
590    o gmredi (fm07):
591      - add lower limit on Transition layer thickness + lower limit on 1/lambda
592      - allow to set few more params from data.gmredi
593    o pkg ggl90:
594          - add missing sqrt(2) factor in computation of mixing length
595            scale in ggl90_calc.F
596            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
597    
598    checkpoint61d
599    o adjoint modifs
600      - adapt to new field rhoInSitu
601      - allow to revert from StoreDynVars2D, StoreDynVars3D
602        to individual fields
603        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
604    o store 3-D (in-situ) density in commom block (DYNVARS.h)
605     - save 1 rho computation.
606     - no longer modify T & S inland when using down_slope pkg.
607    o gad_som : allow to switch to SOM advection for T & S without corresponding
608      pickup files (using new S/R: MDS_CHECK4FILE).
609    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
610      (for useSingleCpuIO to work in multi-threaded)
611    o pkg/shelfice:
612     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
613       with SHELFICEtopoFile in data.shelfice
614     - move code for reading ice shelf topography and modifying hFacC into separate
615       subroutines of the shelfice package
616     - separate initialisation of "fixed" and "variable" variables
617     - kTopC is not (yet) replaced by kSurfC, although this is possible
618    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
619    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
620      and rename:
621      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
622      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
623    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
624    
625    checkpoint61c
626    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
627      to add mass source/sink of fluid in the interior (3-D generalisation
628      of oceanic real-fresh water flux).
629    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
630    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
631    o new pkg: down_slope
632      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
633      - presently, modify T & S inland (dwnslp_calc_rho.F).
634        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
635      - implementation for ocean in P-coords not tested.
636      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
637    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
638      (to facilitate conversion of oceanic pkg to p-coordinate).
639    o change FIND_RHO to FIND_RHO_2D :
640      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
641    o new pkg: cheapaml
642    
643    checkpoint61b
644    o exch2:
645      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
646      - no longer depend on the order sequence (N,S,E,W).
647      - 3rd exchange no longer needed (tested with 24 tiles).
648      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
649      - exch_UV_A-grid readily available (but not yet tested).
650      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
651      (both are no longer needed) in exch_uv: no effect in forward run; but
652       get truncation error differences with adjoint exch.
653    o exch2:
654     - change index-bounds storage (moved from target to local tile,
655       more intuitive this way) ; rename/remove some variables.
656     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
657    
658    checkpoint61a
659    o exch2/matlab-topology-generator:
660      fix bug in index bounds for N-S internal exchange (hard to tell if this
661      had any effect on the solution).
662    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
663      is exceeded
664    o testreport: modify syntax of awk, so that it works also with
665      awk, and not only with nawk and gawk
666    
667    checkpoint61
668    o autodiff
669      Change default for TAF usage by removing argument '-nonew_arg'
670      This changes TAF subroutine argument list (ordering of active var.)
671      Omission of this flag leads to incompatibility w.r.t. TAMC
672      To restore TAMC-compatibility, need following modifs:
673      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
674      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
675      Tested TAF version is 1.9.22
676      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
677    
678    checkpoint60
679    --->>> This is the last checkpoint for which generating the adjoint
680    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
681    --->>> by default.
682    --->>> Future checkpoints will ommit this flag by default.
683    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
684    o pkg/grdchk: Add gradient check to etan0 perturbations.
685    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
686    o pkg/autodiff: more flexibility in zeroadj.
687      model/src: modifying do_oceanic_phys.F accordingly.
688    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
689    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
690      special setup of gmredi for which the adjoint is stable
691      enough for parameter optimization.
692    o bridging the gap between eddy stress and GM.
693      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
694          along with a change in CPP option (now ALLOW_EDDYPSI).
695      -> when using GM w/ GM_AdvForm:
696          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
697          is applied either in the tracer Eq. or in momentum Eq.
698          depending on data.gmredi (intro. GM_InMomAsStress).
699      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
700      The key modifications are in model/src/taueddy_external_forcing.F
701      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F

704    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
705      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
706      fix option to read coriolis(@ cell-corner) from files with CS-grid.
707    o pkg/mnc: add some attributes to standard 1D-coordinate variables
708    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
709      mass points, when using mnc for output
710      - add runtime parameter (missing_value, missing_value_int) to override
711        default (which is the value of getcon('UNDEF'))
712    o pkg/mnc: prepare mnc for the actual use of missing values with the
713      diagnostics package: small fix in mnc_cw_readwrite.template and more
714      initialisation of never used fields
715      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
716      versions
717    o pkg/thsice/thsice_ini_vars.F added default initial values so that
718      thermodynamics sea ice solver does not blow up when some initial fields
719      are missing.
720    o move from external_forcing_surf.F to ini_forcing.F
721      the p-coord. hack consisting in using pLoad to set phi0surf ;
722      update output of tutorial_global_oce_in_p (affected @ truncation level).
723    o Freshen up a bit hs94.1x64x5, notably:
724      remove rotationPeriod and tRef=5*0. (adjoint only), and add
725      exactConserv=.TRUE.
726    o pkg/generic_advdiff:
727      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
728      applies to files where Temperature & Salinity 2nd Order moments are used.
729    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
730      this uses a dynamically allocated internal state data structure
731      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
732      and requires a fortran 90 compiler
733    
734    checkpoint59q
735    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
736       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
737    o Refresh tutorial_global_oce_biogeo, notably:
738      - change bathymetry (put back seamounts in ACC, use hFacs)
739      - change EOS (POLY3 --> JMD95Z)
740      - use Bryan-Lewis vertical diffusivity
741      - use multidimensional advection
742      - remove old virtual virtual in dic pkg, now done through ptracer pkg
743      - change a couple of parameters in dic pkg
744    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
745    o pkg/obcs: change default to OBCSfixTopo = .true.,
746      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
747      - replace "debugMode" with "debugLevel .GE. debLevB"
748    o implementation of TAF directives for gchem,cfc,dic
749    o remove "exp5" (replaced by tutorial_deep_convection).
750    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
751      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
752      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
753      --> changes results in exp4, seaice_obcs
754    o tutorial_deep_convection :
755      update the set-up and increase resolution and domain size ; start
756      from pseudo initial conditions = output at t=120mn in order to see
757      something happening when running testreport.
758    o pkg/seaice: add os7mp as an advection scheme
759                  add check for advection schemes
760                  add a flag for restoring T and S underneath sea ice
761    o pkg/my82: add netcdf-support and diagnostics
762    o thsice pkg:
763      - Now hsMax limits snow height by turning it into ice following
764        flooding scheme (and now conserving energy)
765      - Slight rewriting of the formula in thsice_calc_thick.F
766      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
767      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
768    
769    checkpoint59p
770    o gchem / dic / cfc :
771      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
772      - add new parameter files: "data.dic" & "data.cfc" ;
773      - various re-arrangement in initialisation & header file ;
774      - fix tutorial_global_oce_biogeo for multi-threaded test.
775    o pkg/dic: test for "pickup_dic" file when restarting ;
776      if no pickup-file, can restart with a re-initialised pH (same as it did
777      before) providing pickupStrictlyMatch is set to False.
778    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
779      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
780    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
781      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
782    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
783     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
784       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
785    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
786       scheme to use for vorticty-term ;
787     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
788       (with default selectVortScheme, return to original discretisation)
789     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
790    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
791    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
792      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
793      also fix diagnostics VISCAHW & VISCA4W.
794    
795    checkpoint59o
796    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
797    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
798      move a few statemens out the main loop into separate loops
799    o pkg/shelfice:
800      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
801        (kg/m^2/s), does not break tests, because in verification/isomip,
802        rhoConstFresh=rhoConst (by accident)
803      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
804      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
805        new file model/src/seawater.F, so that they are available for all pkgs.
806      - convert potential temperature into in-situ temperature. This changes the
807        isomip tests => update tests
808    o add a flag writePickupAtEnd (default=true) to be able to suppress
809      writing a pickup at the last timestep
810    o tools/mpack-1.6 :
811      - disable automake (not working) and autoconf (not needed).
812      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
813        also cleaner with much less compilation warnings.
814    o pkg/profiles:
815      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
816      (for "less than 32 characters name" compiler requirement)
817    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
818      conditions that have a different sampling frequency than S/T/U/V obcs
819    o pkg/diagnostics (stats-diags):
820      - fix global Min/Max in case 1 processor get only empty tiles
821    o genmake2: replace (4 times)
822         make genmake_tc_1.o >> genmake_warnings 2>&1
823      with
824         COMM="$CC $CFLAGS -c genmake_tc_1.c"
825         echo $COMM >> genmake_warnings
826         $COMM >> genmake_warnings 2>&1
827      to make genmake2 always see the value of CC as specified in the optfile.
828    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
829      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
830      - modify verification advect_cs test to test SOM-advection on CS-grid.
831    o pkg/ctrl:
832      - Rewrite of ctrl_map_ini_ecco.F,
833        introducing a generic routine (ctrl_map_ini_gen.F).
834      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
835    
836    checkpoint59n
837    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
838      number in dedicate array "hdiag":
839      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
840        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
841      - many small changes (integer format) for large number of diagnostics
842      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
843        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
844    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
845      usingSphericalGrid, this allows to define the rotated grid coordinates
846      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
847      geographical coordinates according to the inverse of the rotation defined
848      by the Euler angles, so that Coriolis parameter and online-interpolation by
849      exf works with the geographical coordinates on XC/YC/XG/YG.
850      Naturally, this feature does not work with all packages, so some
851      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
852      profiles), because there the coordinates are assumed to be regular
853      spherical grid coordinates.
854    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
855      - introduce isopycnal diffusion coefficient control.
856    o tools/adjoint_options:
857      - additional control vector components.
858    o pkg/mnc: have mnc create marginally meaning full coordinate variables
859      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
860    o pkg/mypackage:
861      - add example of read/write pickup for state-var ;
862      - add entry points to the main code for state-vars diags & write-pickup.
863    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
864      transitions for useExfYearlyFields
865      - add new subroutine that determines the file to read from for
866        use*YearlyFields = .TRUE. and .FALSE.
867      - add a verification experiment to global_with_exf that tests
868        useExfYearlyFields with USE_EXF_INTERPOLATION defined
869    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
870      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
871      subroutines (which could be generated from a template, because they are
872      almost identical), for now they are included in obcs_prescribe_read.F for
873      simplicity
874    o pkg/exf:
875      - add a little more diagnostic to exf_interp_read (in analogy to
876        mds_read_field, can be turned off with debugLevel < debugLevA=1)
877      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
878        ugly but fast by unrolling short inner loops, inserting a unroll=8
879        directive in routine lagran, and splitting a loop and making do while the
880        outermost loop (the latter requires the intoduction of index arrays)
881    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
882    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
883      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
884    o verification/seaice_obcs: updated for restart test and latest options
885    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
886      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
887      for now this is only available for the C-grid code and also within
888      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
889    
890    checkpoint59m
891    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
892      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
893    o gad_som : fix flux output (& diagnostics) to have same units as other  
894      advection scheme fluxes (was previously multiplied by deltaT).  
895    o added verification/seaice_obcs both to test seaice open boundaries
896      and to provide an example matlab scrpt for generating them
897    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
898    o pkg/salt_plume: clean up salt_plume_frac.F to
899      remove redundancy in PlumeMethod 1 and 4
900    o pkg/kpp: added saltplume diagnostics
901    o pkg/obcs and pkg/seaice:
902      - do not set uice and vice to zero when OB*icefile are unspecified
903      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
904      - moved seaice tracer obcs after call to seaice_growth
905    o pkg/salt_plume: added various options for salt plume depth
906      criterion and for vertical distribution of the salt
907    
908    checkpoint59l
909    o pkg/ptracers: new version of ptracers pickup:
910      read meta file and write only fields which are needed to restart.
911      ( same logic as main pickup file ; also using pickupStrictlyMatch )
912    o pkg/seaice:
913      - add timescale for melting due to warm mixed layer as a means of
914        setting SEAICE_availHeatFrac more conveniently
915      - add a CPP-flag/runtime parameter check for flooding algorithm
916      - reformulated availHeat in seaice_growth.F to be independent of AREA
917    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
918      unit changes
919    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
920    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
921      SX vector computer.
922    o pkg/seaice:
923      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
924        seaice forcing fields can now be read only through pkg/exf
925      - removed some unused halos
926    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
927    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
928      or U/VICE from U/VWIND before computing U/VSTRESS
929    
930    checkpoint59k
931    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
932      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
933    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
934      all experiments pass when compile with un-initialised var. checking option.
935    o added pkg/salt_plume
936    o script to test restart (for now, in MITgcm_contrib/jmc_script)
937    o pkg/seaice: new read/write pickup version.
938      read meta file and write only fields which are needed to restart.
939      ( same logic as main pickup file ; also using pickupStrictlyMatch )
940    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
941    o lab_sea.hb87: modify the domain & update output.hb87.txt :
942      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
943      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
944      process. Fixed here by closing the domain at the Northern boundary.
945    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
946    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
947      a set of consecutive levels in/from a 3-D array.
948    o pkg/ptracers:
949      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
950      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
951    
952    checkpoint59j
953    o in pkgs: dic, obcs, offline, rbcs:
954      standard way to compute coeff. for time interpolation between 2 time reccords
955      which retains full precision (& make results less dependent on compiler).
956      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
957    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
958      packages instead of reading ice cover and wind speed separately
959    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
960     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
961      to allow to compile customized code before the update)
962    o cleaning-up:
963      - fix CPP instruction syntax in pkg/obcs
964      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
965        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
966      - fix some threads issue in IO parts.
967    o pkg/dic:
968      - add tons of "_d 0" (--> much better testreports !)
969       and then update outputs of tutorial_global_oce_biogeo
970    o pkg/mom_fluxform:
971      add a special version of momentum advection intended to conserve momentum
972      next to a bathymetry step or a coastline edge. (default = off = #undef)
973    o new read/write pickup version:
974      - for now, only implemented for main (mdsio) pickup file.
975      - write out only what is needed to restart; merge pickup_nh , pickup_ph
976        and main pickup together.
977      - read meta file; read only what is needed to restart; stop if a field
978        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
979        if it make sense (even if the restart is not perfect).
980      - if no meta file, assume that pickup to read corresponds exactly to
981        a pickup that would currently be written.
982      - read pickup written in the old format (until checkpoint59i) if it
983        recognizes an old meta file (no field-list).
984      - add a meta file in exp. which starts from a pickup: 2 cases:
985        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
986         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
987        b) a meta file describing the content of the associated pickup file
988         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
989    o pkg/mdsio & pkg/rw:
990      - new routine to read a meta file ; new set of routine to read
991        Multiple-fields file (with meta file).
992    o added open boundary conditions capability for seaice
993        HSNOW, HSALT, UICE, and VICE
994    
995    checkpoint59i
996    o adjoint:
997      * fix multiDimAdvection adjoint
998        (partial recomputation problem by TAF for fVerT(:,:,kDown)
999        and comlev1 size definition (maxpass vs. max. number of tracers)
1000      * verification/global_ocean.90x45x15 adjoint now tests
1001        NLFS and multiDimAdvection using DST3 (=30)
1002      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
1003    o pkg/kpp: add "_d 0" to real constant (if missing);
1004      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
1005      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
1006    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
1007      for internal parameters related to restart process (formerly from PARAMS.h)
1008      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
1009    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
1010      as argument. (only atm2d & obcs write_pickup have not yet been updated)
1011    o pkg/monitor:
1012      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
1013      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
1014      - account for deep Atmosphere factor and density factor (anelastic)
1015    o added open boundary conditions capability for seaice HEFF and AREA
1016    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
1017      thermodynamics
1018      - requires a little reorganization, which affects the testreport results
1019        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
1020        so that now the conservative form is tested
1021      - add a few comments
1022    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
1023    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
1024    o add new diagnostics to seaice: advective, diffusive fluxes (only for
1025      multidim-advection, for scheme 2 they are not filled) and transports,
1026      thermodynamic growth rates
1027    o change units of EmPmR (inside the code, + within coupling interface)
1028      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
1029      Affects results @ truncation level (cg2d match) and update output of
1030       experiments: lab_sea(6), global_ocean.90x40x15(10),
1031      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
1032      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
1033      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
1034      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
1035    
1036    checkpoint59h
1037    o pkg/exf:
1038      - improve vectorization by moving if-statement out of loops in
1039        exf_mapfields, exf_radiation
1040      - exf_bulkformulae.F: introduce 2D fields and vectorize code
1041    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
1042    o testreport:
1043      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
1044        monitor & update offline_exf_seaice exp. output.
1045      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
1046    o pkg/seaice:
1047      - bug fix in the evp solver: boundary conditions were affected be
1048        masking of zMax/zMin (changes results)
1049      - minor bug fix in boundary conditions in seaice_calc_strainrates
1050        (changes results for no_slip)
1051      - seaice_lsr.F: make interpolation of eta dependent on boundaries
1052      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
1053      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
1054        stress formulation and no-slip boundary conditions
1055    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
1056      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
1057    o pkg/seaice: a first HSALT time stepping equation has been checked in
1058    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
1059      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
1060      without requiring DO-IF statements
1061    o pkg/thsice:
1062      use continuous power-law function for partition of energy between lateral
1063      melting/freezing and thinning/thickening ; old code using step function
1064      still available with #undef THSICE_FRACEN_POWERLAW
1065      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
1066    o testreport: change AD testing : check against results/output_adm.txt
1067      using same scripts as for forward test.
1068    
1069    checkpoint59g
1070    o adjoint testing: in preparation for changing testreport:
1071      - output format: cost and grad written on separated lines
1072      - ad output results in directory "results" (instead of "results_ad")
1073    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
1074    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
1075    o pkg/ecco: allow user defined cost function contributions
1076    o testreport:
1077      Allow to choose (per experiment) the list of tested output variables
1078       and the main variable (used to issue a pass/FAIL ) ;
1079      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
1080      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
1081      Also modify printing of summary:
1082       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
1083       b) echo the list of tested variables in the individual summary.txt of
1084          each experiment.
1085    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
1086      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
1087      (but still depend on the tile decompostion of the domain).
1088    o pkg/seaice: change a discretization detail to make the B-grid code
1089      "more symmetric". This change is likely to remove all "ridges/leads" that
1090      where quasi-aligned with the grid in B-grid solutions. It may also be
1091      the solution to the stress coupling issues with the B-grid.
1092    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
1093      remove .cvsignore from input dir. (since testreport no longer run here).
1094    o pkg/thsice:
1095     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
1096     - fix reshaping of sea-ice just after advection:
1097       melt all the ice only if ice-volume is too small.
1098     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
1099       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
1100     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
1101    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
1102      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
1103    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
1104      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
1105      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
1106      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
1107      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
1108      -> update output.txt
1109    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
1110     this affects truncation error: -> update output.txt of exp:
1111      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
1112      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
1113    
1114    checkpoint59f
1115    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
1116    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
1117      a bounded range (in forward mode)
1118    o pkg/ecco, ctrl, autodiff and mom_common:
1119     internal parameter controls, completements of implementations
1120    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
1121    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
1122      (not seem any difference in testing results).
1123    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
1124       at face corners.
1125    o pkg/generic_advdiff:
1126     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
1127      loop range indices for computing vertical advection tendency
1128      and do the calculation in the interior only (no overlap) ;
1129      for now, only implemented for SOM advection (to save CPU time).
1130     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
1131    o exch2 adjoint
1132      First set of changes:
1133      - add exch2 hand-written adjoint templates
1134      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
1135        This will require cleanup in pkg/autodiff/*.F
1136        (changed routines currently kept separate in verif. code/)
1137      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
1138        that used to hide exch2 or cubed-sphere specific code
1139        (commented via 'cph-exch2')
1140    o pkg/seaice
1141      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
1142    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
1143       output of global_ocean.cs32x15.thsice .
1144    
1145    checkpoint59e
1146    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
1147      for B-grid vector (not yet tested) and C-grid vector (<- only used
1148      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
1149    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
1150      (#ifdef ALLOW_SALT_PLUME)
1151    o gather_2d/scatter_2d: removed halo regions
1152    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
1153      scheme and the corresponding test case (under front_relax dir). For now,
1154      only available with Skew-flux form and not yet tested in realistic set-up.
1155      adjoint: store directives updated, but gradient checks deteriorated,
1156      so maybe GM/Redi adjoint is now broken.
1157    o seaice adjoint
1158      * add AREA, HEFF, HSNOW as control variable
1159        (should not change lab_sea results)
1160      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
1161    o pkg/seaice:
1162      * added computation of saltFlux in seaice_growth;
1163        For time being, sea ice salinity is assumed constant
1164        contribution of snow flooding to freshening of sea ice is neglected.
1165        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
1166        defaults to 0.0 in order to maintain backward compatibility.
1167        Typical values for SEAICE_salinity are 4 to 10 g/kg.
1168      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
1169      * added SEAICE_availHeatFrac, which specifies fraction of surface level
1170        heat content used to melt or grow ice
1171      * commented out cap of HICE: it helps keep ice thinner
1172      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
1173      * applied OBCS T/S mask to HEFFM sea ice mask
1174    
1175    checkpoint59d
1176    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
1177     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
1178     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
1179    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
1180     and change default value of parameter "GM_Small_Number";
1181     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
1182       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
1183       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
1184    o pkg/ecco: cost function when applying pkg/smooth to controls
1185    o pkg/ctrl: add forcingPrecond run time parameter
1186    o pkg/seaice:
1187     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
1188     - fix bug in metric terms of u-equation in LSR solver (implicit part),
1189       changes verification/lab_sea
1190     - rearrange implicit part of u-equation in LSR solver to make it easier to
1191       read, understand, and debug. This causes changes at the truncation level.
1192     - fix (serious) bug in the boundary conditions (sign error in the implicit
1193       part) of the LSR solver. Changes all LSR results.
1194     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1195       is initilized with small values - does not change lab_sea results.
1196     - added HsnowFile initialization capability
1197    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1198     initialization of pkg/smooth and application to control vector
1199    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
1200    o dependencies: pkg/profiles requires pkg/cal
1201    o pkg/profiles:
1202     - added option ALLOW_PROFILES_GENERICGRID
1203         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1204         that interpolation information (grid points and coefficients) is provided
1205         within the netcdf input files.
1206         -> sample matlab scripts can be found in MITgcm_contrib/gael
1207         that allow you to prepare netcdf input files.
1208     - also modified: cleaner include statements, cleaner error print statements,
1209       cleaner stops when error, and more tests of the netcdf input files consistency.
1210    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1211    o pkg/seaice:
1212     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1213       requires a new routine: seaice_diagnostics_fill.F
1214     - make sure that seaice does not move if not forced (pressure replacement
1215       method, Hibler and Ip, 1995), changes results
1216     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1217     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1218       It is turned off by default (=-1.), because it changes the results.
1219     - make it possible to read AREA from a file, too.
1220    
1221    checkpoint59c
1222    o add S/R and diagnostics for oceanic mixed-layer depth
1223    o move GMRedi call after all vertical mixing schemes (including KPP)
1224    o pkg/thsice:
1225     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1226      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1227    o pkg/obcs:
1228     - bug fix for balance code
1229    o pkg/seaice:
1230      - allow values of SEAICE_elasticParm > 1
1231      - add new parameter SEAICE_evpTauRelax as an alternative
1232        to SEAICE_elasticParm
1233      - make lsr boundary conditions free slip (by default), changes result
1234      - add code for no slip boundary conditions for lsr
1235      - set minimum of zeta to zero (and not 4e8) (changes results)
1236      - add a cap on AREA after advecting AREA if seaice_growth is not called
1237    o change calculation of Visbeck K:
1238      - no longer depend on tapering scheme; instead, compute slope (limited
1239        by GM_maxSlope). this is equivalent to what was comuted before with
1240        clipping or linear tappering.
1241      - fix vertical averaging (wrong by 1/2 level)
1242      - leave the old version (but will not be maintained) within
1243        #ifdef OLD_VISBECK_CALC / #endif
1244      - update output of exp. ideal_2D_oce
1245    o change error catch in calc_r_star to improve vectorization
1246    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1247      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1248    o adjoint:
1249      Re-organized adjoint checkpointing according to Matt Mazloff
1250      (but with modifs/completions/cleanups)
1251      Storing is now bundled into large arrays to optimized I/O
1252      (and second step in cleanup of the_main_loop)
1253    
1254    checkpoint59b
1255    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1256      - export/import (between ocean & coupler) fields needed for ocean DIC.
1257    o pkg/seaice:
1258      - get rid of three more exchanges seaice_calc_viscosities (required
1259        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1260      - bug fix in seaice_ocean_stress (update of lab_sea required)
1261      - reduce loop boundaries to necessary minimum also in seaice_evp
1262      - go back to the old way of computing deltaC/Z as the adjoint likes that
1263        better
1264    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1265      passive tracer to an Age Tracer) + update output.txt
1266    o pkg/exf:
1267      - implement A-grid / C-grid selection for wind-stress input files.
1268      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1269      for now, in exf_bulk_largeyeager04.F only :
1270      - change implementation for case where windspeed + 2. components wind-stress
1271        are read-in. AND use rhoConstFresh to convert evap.
1272    o pkg/seaice:
1273      - use correct EXCH_UV for wind-forcing (on A-grid).
1274      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1275        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1276    o pkg/exf:
1277      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1278      EXF_INTERPOLATION:
1279      - merge global_with_exf/code version of exf_interp_read.F
1280        to the main code ;
1281      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1282        reading the file ; Important: This options needs to be defined to recover
1283        previous code.
1284        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1285      - no longer loose real*8 precision along the way when using exf_iprec=64.
1286  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1287      - change discretisation of evp-solver in order to avoid another exchange
1288        (changes lab_sea) and clean up a little
1289      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1290        help the adjoint (this also changes the results slightly)
1291      - add a few "_d 0" where they had been missing in seaice_evp.F
1292      - cleaning up: remove unused seaice_calc_rhs.F
