4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o adjoint:
8      * update and finish work on adjoint of dic package (G. Forget)
9      * start adjoint of offline package
10      * bug fix for cube-sphere TLM code (active_file_g.F)
11    o tutorial_global_oce_optim:
12      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
13      and add SIZE.h_mpi for MPI testing
14    o pkg autodiff
15     - fix bug in autodiff_restore
16     - make genmake2 remove comments and empty lines from ad_input_code.f in
17       order to reduce file size (new script file remove_comments_sed)
18    o allows to specify vertical profile of vertical viscosity (viscArNr)
19    o pkg autodiff
20      autodiff_ini_model_io: comment out writing of grid information to netcdf
21      files, because at this time the grid fields are a bunch of zeros
22      (this is analogous to ini_mnc_vars.F)
23    o pkg seaice/autodiff:
24     left-over from removing the 3-time-level fields:
25     - small rearrangement of common blocks (SEAICE.h)
26     - fix field declaration in order to get meaningful output in
27       adseaice.*.nc (adcommon.h)
28    o pkg obcs:
29     - go through NH code only if nonHydrostatic=T
30     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
31     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
32       => Update output of experiment seaice_obcs
33     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
34     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
35     - fix restart for useOBCSprescribe + useEXF
36    o pkg ctrl
37     - make obcs as control parameter work also with useSingleCPUio
38     - replace a few sny and snx by Ny and Nx to be consistent with
39       ctrl_set_globfld_x/yz.F
40    o pkg seaice
41     - re-introduce global field frWtrAtm for the case of
42       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
43     - catch the case of an empty filename in seaice_cost_init_fixed.F
44    o pkg ecco:
45     - small bug fixes in the_main_loop
46      . fix order of monitor arguments
47      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
48      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
49        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
50     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
51       imbalance diagnostics for wmean_h/sflux = 0
52     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
53     - catch the case of empty filenames in ecco_cost_init_fixed.F
54       and ecco_readparms.F
55     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
56       to make this statement meaningfull in ecco_cost_weights.F
57    o pkg zonal_filt:
58      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
59      - when using rStar, filter uVel*hFacW instead of uVel
60       (tested without topography: fix a Pb of growing instability with NLFS)
61    o pkg/aim/thsice:
62     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
63      (works as SST restoring)
64    o pkg/thsice:
65     -add specific parameter for salt restoring in slab mixed-layer
66       (by default equal to the temperature restoring)
67    
68    checkpoint61v
69    o pkg/kpp:
70     -add double diffusive contributions as a hack, turned off by default
71      for now, and the code can be excluded with a CPP-flag
72      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
73     -add a verification experiments to "vermix" to test this code
74    o pkg/mom_common:
75      Move computation of length scales to mom_init_fixed.F (avoid recomputation
76      at each time-steps*levels).
77    o pkg/layers:
78      Created a new package for computing volume fluxes in temperature or
79      [not yet implemented] density layers, e.g. for calculating residual
80      overturning circulations.
81    o pkg/diagnostics:
82      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
83    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
84    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
85      To avoid mixing type (RS/RL) of input/output array argument,
86      replace single mixed-type array with a pair from each type (RS/RL).
87    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
88      is now implemented for all pkgs (previously only done for the main pickup)
89    
90    checkpoint61u
91    o pkg/obcs:
92      - change OB?eta from _RS to _RL and put them into a separate commen block
93      - add code to read OB?eta from a file via obcs_prescribe_read: the code
94        compiles and does not destroy any other experiments, the data is read
95        properly, but the code is not tested in actual applications
96    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
97      create a meaningful unit attribute for the time coordinate variable
98    o pkg/ebm: add plenty of missing "_d 0" ;
99       update results of experiment global_ocean_ebm (fwd + adjoint tests)
100      Notes: several pieces of code only works for (very) specific set up
101       (domain size, lat range, etc ...); should be documented & stop if one
102       of those assumptions is not meet.
103    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
104       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
105          and offline_exf_seaice (seaicetd + adjoint).
106    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
107       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
108        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
109    o few changes to pass when compiling with strick checking of arguments
110       across S/R (allow to find few bugs in S/R calls).
111    o pkg/seaice:
112     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
113       2d-fields, for slightly better performance
114    
115    checkpoint61t
116    o pkg/seaice:
117     - remove unused variables in seaice_evp
118     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
119    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
120       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
121       each processor opens a different file (a fix from Matt).
122    o cg2d:
123       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
124       this reduces number of EXCH calls by 2 when using exch2.
125       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
126       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
127    o pkg/thsice:
128       add code for Near Infra-Red albedo (from Jeff)
129       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
130    o ini_model_io:
131       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
132       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
133       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
134    
135    checkpoint61s
136    o pkg/exch2 (exch2_rxN_cube*):
137       remove last BARRIER (no need to synchronise after getting data from shared
138       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
139    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
140      and generate new output (for the 2 tests) using default rotationPeriod.
141    o pkg/exch2:
142      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
143        (was already the case with AUTODIFF_EXCH2 defined)
144      - add bj in exch2 arrays and S/R.
145      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
146        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
147    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
148      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
149        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
150      - verification experiment natl_box.longstep
151    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
152      allow different versions of ifort (8 or 9) and different versions
153       of mpi (mpich or mpich2) to be used with the same optfile.
154      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
155       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
156    o pkg/seaice:
157      fix previous modif (3-level field removed) for old-pickup reading
158    
159    checkpoint61r
160    o pkg/seaice:
161     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
162      1. introduce fields for time step (N-1)
163      2. do not use levels 2 and 3 anymore (but keep them)
164      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
165         includes changes to pkg/thsice/thsice_get_velocity.F,
166         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
167         pkg/obcs/obcs_apply_uvice.F.
168     - completely remove code for leap-frog time stepping for second order
169       advection
170     - adjusted adjoint accordingly;
171       gradient checks have improved by an order of magnitude!
172    
173    checkpoint61q
174    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
175     - the boundary conditions along open boundaries are unclear, because the
176       associated masks are set to zero and are thus treated as closed when
177       applying the slip-boundary conditions.
178     - move initialisation of grid variables from seaice_init_varia to _fixed
179    o adding doc/diags_changes.txt
180    o model/src:
181      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
182       to avoid "_diags" naming if no relation to pkg/diagnostics.
183      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
184       file and only call PLOT_FIELD_XYZ if debugMode=T.
185      remove few PLOT_FIELD_XY calls outside initialisation.
186      remove few unnecessary BARRIER.
187    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
188      of salt_plume package in Southern Ocean
189    o pkg/thsice:
190     - fix hOceMxL in overlap (needed for sea-ice advection);
191       update output of experiment global_ocean.cs32x15.icedyn.
192    o pkg/seaice:
193     - make the (placeholder-)tracer IceAge a little more meaningful
194      by avoiding ridging of age due to convergent ice flow
195     - add diagnostics for surface temperature, atmospheric and oceanic
196       heat flux, and atmospheric and oceanic ice growth
197    
198    checkpoint61p
199    o eesupp (global_max & global_sum):
200     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
201     - remove starting & endding barrier (no longer needed)
202    o pkg/mdsio, writelocal:
203       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
204       (remove the STOP): uses shared buffer IO to store data from all threads
205       and then let master-thread write nThreads tiles.
206    o pkg/mdsio (read/write field):
207     - tiled IO done in 1 piece (all levels at a time);
208     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
209     - multi-threaded: allow to read/write local (non-shared) array
210       (was already working with singleCpuIO ; now works also without);
211       => no longer needs barrier call after reading a file (added inside
212       mds_read/write field).
213     - move barrier calls outside gather/scatter_2d to mds_read/write_field
214    o pkg/obcs/exf
215      - exf_getffieldrec.F: add a few ". _d 0" and
216                            add code to catch the case fldperiod = 0.  
217      - obcs_precribe_read.F: change if statements so that they match
218                              the variable type (_RL)
219      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
220        exf_iprec) as part of namelist EXF_NML_01
221    o pkg/mdsio:
222      - read/write tiled (local) files: read/write 1-level tile chunk at a time
223        (instead of segment of length sNx); expected to speed up tiled IO.
224    o pkg/exch2:
225      - take buffer copy from/to array out of S/R exch2_send/recv into new
226        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
227        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
228      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
229      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
230        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
231        including Topology header file (and common blocks).
232      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
233        remove 2nd exch call in exch2_s3d_rx (no longer needed).
234      - document S/R arg. list (+ update some comments)
235    o pkg/seaice:
236      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
237        temperature and humidity over sea ice based on climatological values.
238      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
239        of LSR (this change is expected to change the results slightly because now
240        it uses slightly difference moduli from the second last LSR solution, but
241        that is more consistent with the stress computations; this part of the code
242        is not tested in the verification experiments)
243      - fix diagnostics for flux of ice in case of B-grid
244      - turn strain rates eij and press into global fields within global
245        common block in SEAICE.h for more straighforward diagnostics
246      - fix diagnostics for principal stress components, press, zeta, eta
247        to give something meaning full
248    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
249      new output (all 4 tests) using default rotationPeriod.
250    o pkg KPP:
251      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
252      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
253        and normal grid from 1 to Nr)
254    o Fix computations of L4rdt in mom_calc_visc.F
255    o eesupp:
256      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
257      should be called before a "stop" if we know that all process are going
258      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
259    
260    checkpoint61o
261    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
262    o model/src/ini_curvilinear_grid.F:
263       compute angleSin/CosC when they are not read from a file
264    o pkg/seaice:
265       add pseudo time stepping for LSOR
266    o pkg/exch2:
267       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
268    o pkg/seaice:
269       Adding separate sea ice albedo, drag coefficients, and HO in Southern
270       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
271    o SingleCpuIO:
272       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
273    o pkg/seaice:
274       put exchanged variable in (local) common block for MPI+Multi-Threads
275       to work (necessary with exch1, and for now with exch2 too).
276    o verification: to get more experiments tested with mpi, mth and mpi+mth,
277      change tiling of:
278       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
279       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
280      update output of exp:
281       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
282       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
283      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
284                       (note: output.txt generated on faulks using only 1 tile)
285    o eesupp & mdsio (SingleCpuIO):
286     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
287       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
288       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
289     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
290     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
291       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
292    o pkg/exch2:
293     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
294       read parameter file "data.exch2" if it exists; otherwise try default regular
295       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
296     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
297       with new code (not to be used, just as a backup solution).
298     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
299       in utils/exch2/input.
300    
301    checkpoint61n
302    o eesupp & mdsio (SingleCpuIO):
303      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
304        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
305        receive real*4 array (instead of real*8) to read/write 32.bit files.
306        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
307         and remove new mapping S/R)
308    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
309      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
310        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
311        when using exch2. Add S/R to map global io-buffer to global model array.
312      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
313    
314    checkpoint61m
315    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
316      and add 3 other S/R for other types (R4,R8,RS).
317      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
318    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
319     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
320     - reduce number of macro definitions (keep only those which are used);
321       can always call directly the corrresponding S/R if needed.
322     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
323       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
324     Fixed wrong type of arg in:
325       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
326       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
327     To fix: global_sum of var in common block is wrong (multi-threaded) in:
328       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
329     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
330    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
331      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
332    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
333    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
334      edges are closed (zero depth); might happen with "blank tiles";
335      for now, disabled if using OBCS.
336    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
337      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
338    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
339      to reduce length of 1.D array print in STDOUT.
340    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
341      + use 48 tiles (16x8): this will allow to test "blank tiles".
342    o start to test MPI + multi-threaded (change testreport to skip tests
343      where number of tiles do not match).
344    o genmake2: add option "-omp" to turn on Open-MP ;
345      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
346    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
347      and keep the original tile numbering. Note: compatible with old
348      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
349    
350    checkpoint61l
351    o Overlaps had been forgotten in calculating ijk keys : fixed
352    o fix cyrus makedepend for gcc 4.4
353    o experiment fizhi-cs-aqualev20:
354      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
355      and generate new output. Note: new output is much closer to the old
356      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
357      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
358    o pkg/fizhi:
359     - change to avoid indices going deliberately over array-bounds
360     - remove unnecessary MPI stuff
361     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
362     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
363       does not go over array-bounds and therefore returns reliable output.
364     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
365       this S/R has 4 output arguments, which are used inside "get_alarm";
366       when it is called with the same variable "ndum" in place of several
367       output arguments, this produces weird side effect inside "get_alarm"
368      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
369       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
370       address) and produces error.
371    o tools/gemake2: (March 27-29 2009)
372      with option "-mpi": link *_mpi files from "MODS" dir (this is what
373      testreport does).
374    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
375    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
376       update lab_sea.lsr & lab_sea.salt_plume results
377    o pkg/seaice:
378      Major overhaul of the LSOR solver: change discretization from original
379      finite differences to finite volume. The old routine is still in the
380      file seaice_lsr.F and can be turned on with the CPP-flag
381      SEAICE_OLD_AND_BAD_DISCRETIZATION
382      Along with this change, the discretization of the strain rates is changed.
383      The same flag turns on the old discretization in seaice_calc_strainrates.F
384      All verification experiments with seaice are affected (except for
385      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
386      results by setting the above flag.
387      Further changes involve changes in defaults:
388      - ALLOW_FLOODING is defined and turned on by default
389      - SEAICEadvSnow = .true. is now the default
390      - SEAICEadvSalt = .true. is now the default
391      - SEAICEadvAge  = .true. is now the default
392      - SEAICE_clipVelocities  = .false. is now the default
393                                         (as per J. Zhang's recommendation)
394      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
395        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
396      - seaice_growth: replace computation of UG by a simple copy from wspeed
397    
398    checkpoint61k
399    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
400      seaice_lsr: fixed a few metric terms,
401                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
402                  add more debugging diagnostics
403      seaice_evp: removed superfluous many metric terms of FV discretization
404                  of stress divergence
405                  affects lab_sea, lab_sea.hb87
406      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
407                  of stress divergence for non-evp solver
408                  (this part is not tested anywhere)
409      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
410                  they were effectively only half slip
411                  affects lab_sea.hb87
412      updated all relevant verification experiments (except lab_sea//output_adm.txt
413        which was left over, but fails at level 7 & 6)
414    
415    checkpoint61j
416    o pkg/seaice: turn a few hard wired parameters into run time parameters
417    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
418      time in seconds as promised by the usints in seaice_monitor and exf_monitor
419    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
420      that are not cubed-sphere grids
421    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
422    o pkg/ctrl:
423      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
424    o non-hydrostatic (calc_gw.F):
425      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
426      update output of exp. global_ocean.cs32x15.viscA4
427    o remove backward compatibility for thetaMin,phiMin
428      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
429    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
430      interpolated wind field not only for curvilineargrid=.true., but also
431      for a rotated grid (rotateGrid=.true.)
432    o pkg/exf: add capability to bypass interpolation for runoff
433      by setting yet another CPP-flag
434    o eesupp/src, B-grid exchange:
435      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
436    o autodiff
437      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
438      allows to switch to single-prec common blocks;
439      corresponding switch occurs in tamc.h, integer isbyte
440      TAF store directivs "byte" and "kind" seem equivalent;
441      Most tamc.h have been updated correspondingly.
442    
443    checkpoint61i
444    o autodiff:
445      fix autodiff_sore/_restore indices for obcs
446      (spotted by I. Hoteit, M. Mazloff)
447    o pkg/autodiff, pkg/ctrl:
448      Add flag to reduce all tapelev I/O to single-prec.
449      In data.ctrl set
450        doSinglePrecTapelev = .TRUE.
451    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
452      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
453    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
454      real fresh water flux (not yet)
455    o pkg/mdsio & rw:
456     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
457     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
458    o pkg/flt:
459     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
460       init_fixed & ini_varia.
461     - clean-up & simplify linear interpolation S/R:
462       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
463     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
464     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
465     - add vert. coordinate & horiz. indices to output files.
466     - change vertical position in initial condition, from index to depth [m].
467     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
468       (easier to get to a curvilinear grid) ; delX,delY no longer used.
469    o pkg/ggl90: a few modifications:
470     - fix bottom boundary condition, and interpolation of KappaE
471       near top and bottom
472     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
473     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
474     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
475    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
476      (maintain temporary backward compatibility, until next checkpoint)
477    
478    checkpoint61h
479    o pkg/diagnostics with "periodic averaging diagnostics":
480      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
481    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
482    o pkg/obcs: fix loop ranges for balancing code
483    o pkg/flt:
484     - improve criteria for finding which tile owns a float.
485     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
486    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
487      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
488      with ocean biogeo)
489    o pkg/flt:
490     - do some cleaning and fix the restart ;
491     - add output.txt in flt_example/results to get this pkg tested.
492    o genmake2: add an EXTENDED_SRC option and flag.
493       for now, cannot be turned on on command line (only through genmake_local)
494    o pkg/mdsio: read/write vector:
495     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
496     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
497       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
498     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
499      (drop to 4 digits matching for grad). But this test does not look very
500      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
501    
502    checkpoint61g
503    o pkg/flt:
504      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
505       + make OPTIONS file more standard.
506      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
507      - fix _BYTESWAPIO CPP-Flag
508      - standard reading of file-parameter "data.flt"
509      - fix argument list of S/R FLT_RESTART
510      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
511    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
512    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
513      a still unfixed compiler/optimization bug
514    
515    checkpoint61f
516    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
517      update results of global_ocean.cs32x15.icedyn test.
518    o move getcon.F from model/src to pkg/fizhi.
519    o pkg/exf: add parameter for extrapolation of temp up to the surface
520       and option to prevent negative evap (in bulk_largeyeager04 only).
521    o Prather Advection scheme: fix tracer conservation for divergent flow
522      (e.g., when using NonLin Free-Surface).
523    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
524    o gmredi (Visbeck-variable-K):
525     - add more parameters to Visbeck-variable-K.
526     - use a 5 points average for dSigmaR in Visbeck-K calculation
527       (more "homogenous": same stencil and same weights as in dSigmaH)
528     - update output of ideal_2D_oce experiment.
529    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
530      (#undef REAL4_IS_SLOW)
531     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
532       coordinate variable
533     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
534       (surface forcing fields), removes some of the functionality
535     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
536     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
537       probably not all: copy _RS surface flux fields to RL field before
538       calling DIAGNOSTICS_FILL
539     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
540       real*4 (CALL EXCH_*_RS) versions.
541     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
542       (generate new output).
543    
544    checkpoint61e
545    o gmredi (Visbeck-variable-K):
546      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
547      - change computation of Visbeck-K where Slope > Smax :        
548        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
549        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
550    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
551      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
552    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
553    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
554      does not become too large (to avoid precision problems in implicit-diffusion
555      solver); update ideal_2D_oce output.
556    o pkg ggl90:
557      - in ggl90_cal.F: compute only one set of visc/diff, used to
558        step forward TKE/T/S/momentum
559      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
560        have Prandlt =1)
561    o gmredi (fm07):
562      - add lower limit on Transition layer thickness + lower limit on 1/lambda
563      - allow to set few more params from data.gmredi
564    o pkg ggl90:
565          - add missing sqrt(2) factor in computation of mixing length
566            scale in ggl90_calc.F
567            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
568    
569    checkpoint61d
570    o adjoint modifs
571      - adapt to new field rhoInSitu
572      - allow to revert from StoreDynVars2D, StoreDynVars3D
573        to individual fields
574        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
575    o store 3-D (in-situ) density in commom block (DYNVARS.h)
576     - save 1 rho computation.
577     - no longer modify T & S inland when using down_slope pkg.
578    o gad_som : allow to switch to SOM advection for T & S without corresponding
579      pickup files (using new S/R: MDS_CHECK4FILE).
580    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
581      (for useSingleCpuIO to work in multi-threaded)
582    o pkg/shelfice:
583     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
584       with SHELFICEtopoFile in data.shelfice
585     - move code for reading ice shelf topography and modifying hFacC into separate
586       subroutines of the shelfice package
587     - separate initialisation of "fixed" and "variable" variables
588     - kTopC is not (yet) replaced by kSurfC, although this is possible
589    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
590    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
591      and rename:
592      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
593      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
594    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
595    
596    checkpoint61c
597    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
598      to add mass source/sink of fluid in the interior (3-D generalisation
599      of oceanic real-fresh water flux).
600    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
601    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
602    o new pkg: down_slope
603      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
604      - presently, modify T & S inland (dwnslp_calc_rho.F).
605        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
606      - implementation for ocean in P-coords not tested.
607      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
608    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
609      (to facilitate conversion of oceanic pkg to p-coordinate).
610    o change FIND_RHO to FIND_RHO_2D :
611      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
612    o new pkg: cheapaml
613    
614    checkpoint61b
615    o exch2:
616      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
617      - no longer depend on the order sequence (N,S,E,W).
618      - 3rd exchange no longer needed (tested with 24 tiles).
619      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
620      - exch_UV_A-grid readily available (but not yet tested).
621      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
622      (both are no longer needed) in exch_uv: no effect in forward run; but
623       get truncation error differences with adjoint exch.
624    o exch2:
625     - change index-bounds storage (moved from target to local tile,
626       more intuitive this way) ; rename/remove some variables.
627     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
628    
629    checkpoint61a
630    o exch2/matlab-topology-generator:
631      fix bug in index bounds for N-S internal exchange (hard to tell if this
632      had any effect on the solution).
633    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
634      is exceeded
635    o testreport: modify syntax of awk, so that it works also with
636      awk, and not only with nawk and gawk
637    
638    checkpoint61
639    o autodiff
640      Change default for TAF usage by removing argument '-nonew_arg'
641      This changes TAF subroutine argument list (ordering of active var.)
642      Omission of this flag leads to incompatibility w.r.t. TAMC
643      To restore TAMC-compatibility, need following modifs:
644      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
645      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
646      Tested TAF version is 1.9.22
647      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
648    
649    checkpoint60
650    --->>> This is the last checkpoint for which generating the adjoint
651    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
652    --->>> by default.
653    --->>> Future checkpoints will ommit this flag by default.
654    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
655    o pkg/grdchk: Add gradient check to etan0 perturbations.
656    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
657    o pkg/autodiff: more flexibility in zeroadj.
658      model/src: modifying do_oceanic_phys.F accordingly.
659    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
660    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
661      special setup of gmredi for which the adjoint is stable
662      enough for parameter optimization.
663    o bridging the gap between eddy stress and GM.
664      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
665          along with a change in CPP option (now ALLOW_EDDYPSI).
666      -> when using GM w/ GM_AdvForm:
667          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
668          is applied either in the tracer Eq. or in momentum Eq.
669          depending on data.gmredi (intro. GM_InMomAsStress).
670      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
671      The key modifications are in model/src/taueddy_external_forcing.F
672      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
673    
674    checkpoint59r
675    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
676      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
677      fix option to read coriolis(@ cell-corner) from files with CS-grid.
678    o pkg/mnc: add some attributes to standard 1D-coordinate variables
679    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
680      mass points, when using mnc for output
681      - add runtime parameter (missing_value, missing_value_int) to override
682        default (which is the value of getcon('UNDEF'))
683    o pkg/mnc: prepare mnc for the actual use of missing values with the
684      diagnostics package: small fix in mnc_cw_readwrite.template and more
685      initialisation of never used fields
686      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
687      versions
688    o pkg/thsice/thsice_ini_vars.F added default initial values so that
689      thermodynamics sea ice solver does not blow up when some initial fields
690      are missing.
691    o move from external_forcing_surf.F to ini_forcing.F
692      the p-coord. hack consisting in using pLoad to set phi0surf ;
693      update output of tutorial_global_oce_in_p (affected @ truncation level).
694    o Freshen up a bit hs94.1x64x5, notably:
695      remove rotationPeriod and tRef=5*0. (adjoint only), and add
696      exactConserv=.TRUE.
697    o pkg/generic_advdiff:
698      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
699      applies to files where Temperature & Salinity 2nd Order moments are used.
700    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
701      this uses a dynamically allocated internal state data structure
702      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
703      and requires a fortran 90 compiler
704    
705    checkpoint59q
706    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
707       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
708    o Refresh tutorial_global_oce_biogeo, notably:
709      - change bathymetry (put back seamounts in ACC, use hFacs)
710      - change EOS (POLY3 --> JMD95Z)
711      - use Bryan-Lewis vertical diffusivity
712      - use multidimensional advection
713      - remove old virtual virtual in dic pkg, now done through ptracer pkg
714      - change a couple of parameters in dic pkg
715    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
716    o pkg/obcs: change default to OBCSfixTopo = .true.,
717      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
718      - replace "debugMode" with "debugLevel .GE. debLevB"
719    o implementation of TAF directives for gchem,cfc,dic
720    o remove "exp5" (replaced by tutorial_deep_convection).
721    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
722      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
723      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
724      --> changes results in exp4, seaice_obcs
725    o tutorial_deep_convection :
726      update the set-up and increase resolution and domain size ; start
727      from pseudo initial conditions = output at t=120mn in order to see
728      something happening when running testreport.
729    o pkg/seaice: add os7mp as an advection scheme
730                  add check for advection schemes
731                  add a flag for restoring T and S underneath sea ice
732    o pkg/my82: add netcdf-support and diagnostics
733    o thsice pkg:
734      - Now hsMax limits snow height by turning it into ice following
735        flooding scheme (and now conserving energy)
736      - Slight rewriting of the formula in thsice_calc_thick.F
737      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
738      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
739    
740    checkpoint59p
741    o gchem / dic / cfc :
742      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
743      - add new parameter files: "data.dic" & "data.cfc" ;
744      - various re-arrangement in initialisation & header file ;
745      - fix tutorial_global_oce_biogeo for multi-threaded test.
746    o pkg/dic: test for "pickup_dic" file when restarting ;
747      if no pickup-file, can restart with a re-initialised pH (same as it did
748      before) providing pickupStrictlyMatch is set to False.
749    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
750      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
751    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
752      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
753    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
754     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
755       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
756    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
757       scheme to use for vorticty-term ;
758     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
759       (with default selectVortScheme, return to original discretisation)
760     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
761    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
762    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
763      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
764      also fix diagnostics VISCAHW & VISCA4W.
765    
766    checkpoint59o
767    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
768    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
769      move a few statemens out the main loop into separate loops
770    o pkg/shelfice:
771      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
772        (kg/m^2/s), does not break tests, because in verification/isomip,
773        rhoConstFresh=rhoConst (by accident)
774      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
775      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
776        new file model/src/seawater.F, so that they are available for all pkgs.
777      - convert potential temperature into in-situ temperature. This changes the
778        isomip tests => update tests
779    o add a flag writePickupAtEnd (default=true) to be able to suppress
780      writing a pickup at the last timestep
781    o tools/mpack-1.6 :
782      - disable automake (not working) and autoconf (not needed).
783      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
784        also cleaner with much less compilation warnings.
785    o pkg/profiles:
786      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
787      (for "less than 32 characters name" compiler requirement)
788    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
789      conditions that have a different sampling frequency than S/T/U/V obcs
790    o pkg/diagnostics (stats-diags):
791      - fix global Min/Max in case 1 processor get only empty tiles
792    o genmake2: replace (4 times)
793         make genmake_tc_1.o >> genmake_warnings 2>&1
794      with
795         COMM="$CC $CFLAGS -c genmake_tc_1.c"
796         echo $COMM >> genmake_warnings
797         $COMM >> genmake_warnings 2>&1
798      to make genmake2 always see the value of CC as specified in the optfile.
799    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
800      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
801      - modify verification advect_cs test to test SOM-advection on CS-grid.
802    o pkg/ctrl:
803      - Rewrite of ctrl_map_ini_ecco.F,
804        introducing a generic routine (ctrl_map_ini_gen.F).
805      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
806    
807    checkpoint59n
808    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
809      number in dedicate array "hdiag":
810      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
811        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
812      - many small changes (integer format) for large number of diagnostics
813      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
814        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
815    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
816      usingSphericalGrid, this allows to define the rotated grid coordinates
817      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
818      geographical coordinates according to the inverse of the rotation defined
819      by the Euler angles, so that Coriolis parameter and online-interpolation by
820      exf works with the geographical coordinates on XC/YC/XG/YG.
821      Naturally, this feature does not work with all packages, so some
822      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
823      profiles), because there the coordinates are assumed to be regular
824      spherical grid coordinates.
825    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
826      - introduce isopycnal diffusion coefficient control.
827    o tools/adjoint_options:
828      - additional control vector components.
829    o pkg/mnc: have mnc create marginally meaning full coordinate variables
830      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
831    o pkg/mypackage:
832      - add example of read/write pickup for state-var ;
833      - add entry points to the main code for state-vars diags & write-pickup.
834    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
835      transitions for useExfYearlyFields
836      - add new subroutine that determines the file to read from for
837        use*YearlyFields = .TRUE. and .FALSE.
838      - add a verification experiment to global_with_exf that tests
839        useExfYearlyFields with USE_EXF_INTERPOLATION defined
840    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
841      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
842      subroutines (which could be generated from a template, because they are
843      almost identical), for now they are included in obcs_prescribe_read.F for
844      simplicity
845    o pkg/exf:
846      - add a little more diagnostic to exf_interp_read (in analogy to
847        mds_read_field, can be turned off with debugLevel < debugLevA=1)
848      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
849        ugly but fast by unrolling short inner loops, inserting a unroll=8
850        directive in routine lagran, and splitting a loop and making do while the
851        outermost loop (the latter requires the intoduction of index arrays)
852    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
853    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
854      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
855    o verification/seaice_obcs: updated for restart test and latest options
856    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
857      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
858      for now this is only available for the C-grid code and also within
859      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
860    
861    checkpoint59m
862    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
863      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
864    o gad_som : fix flux output (& diagnostics) to have same units as other  
865      advection scheme fluxes (was previously multiplied by deltaT).  
866    o added verification/seaice_obcs both to test seaice open boundaries
867      and to provide an example matlab scrpt for generating them
868    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
869    o pkg/salt_plume: clean up salt_plume_frac.F to
870      remove redundancy in PlumeMethod 1 and 4
871    o pkg/kpp: added saltplume diagnostics
872    o pkg/obcs and pkg/seaice:
873      - do not set uice and vice to zero when OB*icefile are unspecified
874      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
875      - moved seaice tracer obcs after call to seaice_growth
876    o pkg/salt_plume: added various options for salt plume depth
877      criterion and for vertical distribution of the salt
878    
879    checkpoint59l
880    o pkg/ptracers: new version of ptracers pickup:
881      read meta file and write only fields which are needed to restart.
882      ( same logic as main pickup file ; also using pickupStrictlyMatch )
883    o pkg/seaice:
884      - add timescale for melting due to warm mixed layer as a means of
885        setting SEAICE_availHeatFrac more conveniently
886      - add a CPP-flag/runtime parameter check for flooding algorithm
887      - reformulated availHeat in seaice_growth.F to be independent of AREA
888    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
889      unit changes
890    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
891    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
892      SX vector computer.
893    o pkg/seaice:
894      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
895        seaice forcing fields can now be read only through pkg/exf
896      - removed some unused halos
897    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
898    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
899      or U/VICE from U/VWIND before computing U/VSTRESS
900    
901    checkpoint59k
902    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
903      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
904    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
905      all experiments pass when compile with un-initialised var. checking option.
906    o added pkg/salt_plume
907    o script to test restart (for now, in MITgcm_contrib/jmc_script)
908    o pkg/seaice: new read/write pickup version.
909      read meta file and write only fields which are needed to restart.
910      ( same logic as main pickup file ; also using pickupStrictlyMatch )
911    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
912    o lab_sea.hb87: modify the domain & update output.hb87.txt :
913      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
914      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
915      process. Fixed here by closing the domain at the Northern boundary.
916    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
917    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
918      a set of consecutive levels in/from a 3-D array.
919    o pkg/ptracers:
920      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
921      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
922    
923    checkpoint59j
924    o in pkgs: dic, obcs, offline, rbcs:
925      standard way to compute coeff. for time interpolation between 2 time reccords
926      which retains full precision (& make results less dependent on compiler).
927      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
928    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
929      packages instead of reading ice cover and wind speed separately
930    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
931     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
932      to allow to compile customized code before the update)
933    o cleaning-up:
934      - fix CPP instruction syntax in pkg/obcs
935      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
936        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
937      - fix some threads issue in IO parts.
938    o pkg/dic:
939      - add tons of "_d 0" (--> much better testreports !)
940       and then update outputs of tutorial_global_oce_biogeo
941    o pkg/mom_fluxform:
942      add a special version of momentum advection intended to conserve momentum
943      next to a bathymetry step or a coastline edge. (default = off = #undef)
944    o new read/write pickup version:
945      - for now, only implemented for main (mdsio) pickup file.
946      - write out only what is needed to restart; merge pickup_nh , pickup_ph
947        and main pickup together.
948      - read meta file; read only what is needed to restart; stop if a field
949        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
950        if it make sense (even if the restart is not perfect).
951      - if no meta file, assume that pickup to read corresponds exactly to
952        a pickup that would currently be written.
953      - read pickup written in the old format (until checkpoint59i) if it
954        recognizes an old meta file (no field-list).
955      - add a meta file in exp. which starts from a pickup: 2 cases:
956        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
957         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
958        b) a meta file describing the content of the associated pickup file
959         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
960    o pkg/mdsio & pkg/rw:
961      - new routine to read a meta file ; new set of routine to read
962        Multiple-fields file (with meta file).
963    o added open boundary conditions capability for seaice
964        HSNOW, HSALT, UICE, and VICE
965    
966    checkpoint59i
967    o adjoint:
968      * fix multiDimAdvection adjoint
969        (partial recomputation problem by TAF for fVerT(:,:,kDown)
970        and comlev1 size definition (maxpass vs. max. number of tracers)
971      * verification/global_ocean.90x45x15 adjoint now tests
972        NLFS and multiDimAdvection using DST3 (=30)
973      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
974    o pkg/kpp: add "_d 0" to real constant (if missing);
975      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
976      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
977    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
978      for internal parameters related to restart process (formerly from PARAMS.h)
979      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
980    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
981      as argument. (only atm2d & obcs write_pickup have not yet been updated)
982    o pkg/monitor:
983      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
984      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
985      - account for deep Atmosphere factor and density factor (anelastic)
986    o added open boundary conditions capability for seaice HEFF and AREA
987    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
988      thermodynamics
989      - requires a little reorganization, which affects the testreport results
990        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
991        so that now the conservative form is tested
992      - add a few comments
993    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
994    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
995    o add new diagnostics to seaice: advective, diffusive fluxes (only for
996      multidim-advection, for scheme 2 they are not filled) and transports,
997      thermodynamic growth rates
998    o change units of EmPmR (inside the code, + within coupling interface)
999      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
1000      Affects results @ truncation level (cg2d match) and update output of
1001       experiments: lab_sea(6), global_ocean.90x40x15(10),
1002      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
1003      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
1004      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
1005      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
1006    
1007    checkpoint59h
1008    o pkg/exf:
1009      - improve vectorization by moving if-statement out of loops in
1010        exf_mapfields, exf_radiation
1011      - exf_bulkformulae.F: introduce 2D fields and vectorize code
1012    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
1013    o testreport:
1014      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
1015        monitor & update offline_exf_seaice exp. output.
1016      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
1017    o pkg/seaice:
1018      - bug fix in the evp solver: boundary conditions were affected be
1019        masking of zMax/zMin (changes results)
1020      - minor bug fix in boundary conditions in seaice_calc_strainrates
1021        (changes results for no_slip)
1022      - seaice_lsr.F: make interpolation of eta dependent on boundaries
1023      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
1024      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
1025        stress formulation and no-slip boundary conditions
1026    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
1027      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
1028    o pkg/seaice: a first HSALT time stepping equation has been checked in
1029    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
1030      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
1031      without requiring DO-IF statements
1032    o pkg/thsice:
1033      use continuous power-law function for partition of energy between lateral
1034      melting/freezing and thinning/thickening ; old code using step function
1035      still available with #undef THSICE_FRACEN_POWERLAW
1036      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
1037    o testreport: change AD testing : check against results/output_adm.txt
1038      using same scripts as for forward test.
1039    
1040    checkpoint59g
1041    o adjoint testing: in preparation for changing testreport:
1042      - output format: cost and grad written on separated lines
1043      - ad output results in directory "results" (instead of "results_ad")
1044    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
1045    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
1046    o pkg/ecco: allow user defined cost function contributions
1047    o testreport:
1048      Allow to choose (per experiment) the list of tested output variables
1049       and the main variable (used to issue a pass/FAIL ) ;
1050      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
1051      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
1052      Also modify printing of summary:
1053       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
1054       b) echo the list of tested variables in the individual summary.txt of
1055          each experiment.
1056    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
1057      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
1058      (but still depend on the tile decompostion of the domain).
1059    o pkg/seaice: change a discretization detail to make the B-grid code
1060      "more symmetric". This change is likely to remove all "ridges/leads" that
1061      where quasi-aligned with the grid in B-grid solutions. It may also be
1062      the solution to the stress coupling issues with the B-grid.
1063    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
1064      remove .cvsignore from input dir. (since testreport no longer run here).
1065    o pkg/thsice:
1066     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
1067     - fix reshaping of sea-ice just after advection:
1068       melt all the ice only if ice-volume is too small.
1069     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
1070       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
1071     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
1072    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
1073      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
1074    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
1075      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
1076      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
1077      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
1078      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
1079      -> update output.txt
1080    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
1081     this affects truncation error: -> update output.txt of exp:
1082      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
1083      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
1084    
1085    checkpoint59f
1086    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
1087    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
1088      a bounded range (in forward mode)
1089    o pkg/ecco, ctrl, autodiff and mom_common:
1090     internal parameter controls, completements of implementations
1091    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
1092    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
1093      (not seem any difference in testing results).
1094    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
1095       at face corners.
1096    o pkg/generic_advdiff:
1097     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
1098      loop range indices for computing vertical advection tendency
1099      and do the calculation in the interior only (no overlap) ;
1100      for now, only implemented for SOM advection (to save CPU time).
1101     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
1102    o exch2 adjoint
1103      First set of changes:
1104      - add exch2 hand-written adjoint templates
1105      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
1106        This will require cleanup in pkg/autodiff/*.F
1107        (changed routines currently kept separate in verif. code/)
1108      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
1109        that used to hide exch2 or cubed-sphere specific code
1110        (commented via 'cph-exch2')
1111    o pkg/seaice
1112      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
1113    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
1114       output of global_ocean.cs32x15.thsice .
1115    
1116    checkpoint59e
1117    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
1118      for B-grid vector (not yet tested) and C-grid vector (<- only used
1119      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
1120    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
1121      (#ifdef ALLOW_SALT_PLUME)
1122    o gather_2d/scatter_2d: removed halo regions
1123    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
1124      scheme and the corresponding test case (under front_relax dir). For now,
1125      only available with Skew-flux form and not yet tested in realistic set-up.
1126      adjoint: store directives updated, but gradient checks deteriorated,
1127      so maybe GM/Redi adjoint is now broken.
1128    o seaice adjoint
1129      * add AREA, HEFF, HSNOW as control variable
1130        (should not change lab_sea results)
1131      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
1132    o pkg/seaice:
1133      * added computation of saltFlux in seaice_growth;
1134        For time being, sea ice salinity is assumed constant
1135        contribution of snow flooding to freshening of sea ice is neglected.
1136        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
1137        defaults to 0.0 in order to maintain backward compatibility.
1138        Typical values for SEAICE_salinity are 4 to 10 g/kg.
1139      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
1140      * added SEAICE_availHeatFrac, which specifies fraction of surface level
1141        heat content used to melt or grow ice
1142      * commented out cap of HICE: it helps keep ice thinner
1143      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
1144      * applied OBCS T/S mask to HEFFM sea ice mask
1145    
1146    checkpoint59d
1147    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
1148     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
1149     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
1150    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
1151     and change default value of parameter "GM_Small_Number";
1152     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
1153       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
1154       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
1155    o pkg/ecco: cost function when applying pkg/smooth to controls
1156    o pkg/ctrl: add forcingPrecond run time parameter
1157    o pkg/seaice:
1158     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
1159     - fix bug in metric terms of u-equation in LSR solver (implicit part),
1160       changes verification/lab_sea
1161     - rearrange implicit part of u-equation in LSR solver to make it easier to
1162       read, understand, and debug. This causes changes at the truncation level.
1163     - fix (serious) bug in the boundary conditions (sign error in the implicit
1164       part) of the LSR solver. Changes all LSR results.
1165     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1166       is initilized with small values - does not change lab_sea results.
1167     - added HsnowFile initialization capability
1168    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1169     initialization of pkg/smooth and application to control vector
1170    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
1171    o dependencies: pkg/profiles requires pkg/cal
1172    o pkg/profiles:
1173     - added option ALLOW_PROFILES_GENERICGRID
1174         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1175         that interpolation information (grid points and coefficients) is provided
1176         within the netcdf input files.
1177         -> sample matlab scripts can be found in MITgcm_contrib/gael
1178         that allow you to prepare netcdf input files.
1179     - also modified: cleaner include statements, cleaner error print statements,
1180       cleaner stops when error, and more tests of the netcdf input files consistency.
1181    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1182    o pkg/seaice:
1183     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1184       requires a new routine: seaice_diagnostics_fill.F
1185     - make sure that seaice does not move if not forced (pressure replacement
1186       method, Hibler and Ip, 1995), changes results
1187     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1188     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1189       It is turned off by default (=-1.), because it changes the results.
1190     - make it possible to read AREA from a file, too.
1191    
1192    checkpoint59c
1193    o add S/R and diagnostics for oceanic mixed-layer depth
1194    o move GMRedi call after all vertical mixing schemes (including KPP)
1195    o pkg/thsice:
1196     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1197      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1198    o pkg/obcs:
1199     - bug fix for balance code
1200    o pkg/seaice:
1201      - allow values of SEAICE_elasticParm > 1
1202      - add new parameter SEAICE_evpTauRelax as an alternative
1203        to SEAICE_elasticParm
1204      - make lsr boundary conditions free slip (by default), changes result
1205      - add code for no slip boundary conditions for lsr
1206      - set minimum of zeta to zero (and not 4e8) (changes results)
1207      - add a cap on AREA after advecting AREA if seaice_growth is not called
1208    o change calculation of Visbeck K:
1209      - no longer depend on tapering scheme; instead, compute slope (limited
1210        by GM_maxSlope). this is equivalent to what was comuted before with
1211        clipping or linear tappering.
1212      - fix vertical averaging (wrong by 1/2 level)
1213      - leave the old version (but will not be maintained) within
1214        #ifdef OLD_VISBECK_CALC / #endif
1215      - update output of exp. ideal_2D_oce
1216    o change error catch in calc_r_star to improve vectorization
1217    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1218      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1219    o adjoint:
1220      Re-organized adjoint checkpointing according to Matt Mazloff
1221      (but with modifs/completions/cleanups)
1222      Storing is now bundled into large arrays to optimized I/O
1223      (and second step in cleanup of the_main_loop)
1224    
1225    checkpoint59b
1226    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1227      - export/import (between ocean & coupler) fields needed for ocean DIC.
1228    o pkg/seaice:
1229      - get rid of three more exchanges seaice_calc_viscosities (required
1230        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1231      - bug fix in seaice_ocean_stress (update of lab_sea required)
1232      - reduce loop boundaries to necessary minimum also in seaice_evp
1233      - go back to the old way of computing deltaC/Z as the adjoint likes that
1234        better
1235    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1236      passive tracer to an Age Tracer) + update output.txt
1237    o pkg/exf:
1238      - implement A-grid / C-grid selection for wind-stress input files.
1239      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1240      for now, in exf_bulk_largeyeager04.F only :
1241      - change implementation for case where windspeed + 2. components wind-stress
1242        are read-in. AND use rhoConstFresh to convert evap.
1243    o pkg/seaice:
1244      - use correct EXCH_UV for wind-forcing (on A-grid).
1245      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1246        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1247    o pkg/exf:
1248      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1249      EXF_INTERPOLATION:
1250      - merge global_with_exf/code version of exf_interp_read.F
1251        to the main code ;
1252      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1253        reading the file ; Important: This options needs to be defined to recover
1254        previous code.
1255        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1256      - no longer loose real*8 precision along the way when using exf_iprec=64.
1257  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1258      - change discretisation of evp-solver in order to avoid another exchange
1259        (changes lab_sea) and clean up a little
1260      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1261        help the adjoint (this also changes the results slightly)
1262      - add a few "_d 0" where they had been missing in seaice_evp.F
1263      - cleaning up: remove unused seaice_calc_rhs.F
