5      ==============================      ==============================
6    
7    checkpoint61x
8    o adjoint: adding two new verification experiments
9      * tutorial_global_biogeo: an online dic sensitivity experiment
10        (work with G. Forget)
11      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
12        (an update of the Dutkiewicz et al., 2006 paper)
13      Both use the same CO2FLUX cost function, but different controls
14      Gradient checks look good, but some recomp. could still be traightened out
15      Should add xx_dic control variable to test at some point
16    o model/src:
17      add run-time parameters to check and/or mask initial Temp & Salt
18    o pkg/ptracers:
19      apply zonal filter (if used) to all passive tracers
20    
21    checkpoint61w
22    o adjoint:
23      * update and finish work on adjoint of dic package (G. Forget)
24      * start adjoint of offline package
25      * bug fix for cube-sphere TLM code (active_file_g.F)
26    o tutorial_global_oce_optim:
27      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
28      and add SIZE.h_mpi for MPI testing
29    o pkg autodiff
30     - fix bug in autodiff_restore
31     - make genmake2 remove comments and empty lines from ad_input_code.f in
32       order to reduce file size (new script file remove_comments_sed)
33    o allows to specify vertical profile of vertical viscosity (viscArNr)
34    o pkg autodiff
35      autodiff_ini_model_io: comment out writing of grid information to netcdf
36      files, because at this time the grid fields are a bunch of zeros
37      (this is analogous to ini_mnc_vars.F)
38    o pkg seaice/autodiff:
39     left-over from removing the 3-time-level fields:
40     - small rearrangement of common blocks (SEAICE.h)
41     - fix field declaration in order to get meaningful output in
42       adseaice.*.nc (adcommon.h)
43    o pkg obcs:
44     - go through NH code only if nonHydrostatic=T
45     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
46     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
47       => Update output of experiment seaice_obcs
48     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
49     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
50     - fix restart for useOBCSprescribe + useEXF
51    o pkg ctrl
52     - make obcs as control parameter work also with useSingleCPUio
53     - replace a few sny and snx by Ny and Nx to be consistent with
54       ctrl_set_globfld_x/yz.F
55    o pkg seaice
56     - re-introduce global field frWtrAtm for the case of
57       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
58     - catch the case of an empty filename in seaice_cost_init_fixed.F
59    o pkg ecco:
60     - small bug fixes in the_main_loop
61      . fix order of monitor arguments
62      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
63      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
64        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
65     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
66       imbalance diagnostics for wmean_h/sflux = 0
67     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
68     - catch the case of empty filenames in ecco_cost_init_fixed.F
69       and ecco_readparms.F
70     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
71       to make this statement meaningfull in ecco_cost_weights.F
72    o pkg zonal_filt:
73      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
74      - when using rStar, filter uVel*hFacW instead of uVel
75       (tested without topography: fix a Pb of growing instability with NLFS)
76    o pkg/aim/thsice:
77     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
78      (works as SST restoring)
79    o pkg/thsice:
80     -add specific parameter for salt restoring in slab mixed-layer
81       (by default equal to the temperature restoring)
82    
83    checkpoint61v
84    o pkg/kpp:
85     -add double diffusive contributions as a hack, turned off by default
86      for now, and the code can be excluded with a CPP-flag
87      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
88     -add a verification experiments to "vermix" to test this code
89    o pkg/mom_common:
90      Move computation of length scales to mom_init_fixed.F (avoid recomputation
91      at each time-steps*levels).
92    o pkg/layers:
93      Created a new package for computing volume fluxes in temperature or
94      [not yet implemented] density layers, e.g. for calculating residual
95      overturning circulations.
96    o pkg/diagnostics:
97      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
98    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
99    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
100      To avoid mixing type (RS/RL) of input/output array argument,
101      replace single mixed-type array with a pair from each type (RS/RL).
102    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
103      is now implemented for all pkgs (previously only done for the main pickup)
104    
105    checkpoint61u
106    o pkg/obcs:
107      - change OB?eta from _RS to _RL and put them into a separate commen block
108      - add code to read OB?eta from a file via obcs_prescribe_read: the code
109        compiles and does not destroy any other experiments, the data is read
110        properly, but the code is not tested in actual applications
111    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
112      create a meaningful unit attribute for the time coordinate variable
113    o pkg/ebm: add plenty of missing "_d 0" ;
114       update results of experiment global_ocean_ebm (fwd + adjoint tests)
115      Notes: several pieces of code only works for (very) specific set up
116       (domain size, lat range, etc ...); should be documented & stop if one
117       of those assumptions is not meet.
118    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
119       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
120          and offline_exf_seaice (seaicetd + adjoint).
121    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
122       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
123        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
124    o few changes to pass when compiling with strick checking of arguments
125       across S/R (allow to find few bugs in S/R calls).
126    o pkg/seaice:
127     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
128       2d-fields, for slightly better performance
129    
130    checkpoint61t
131    o pkg/seaice:
132     - remove unused variables in seaice_evp
133     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
134    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
135       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
136       each processor opens a different file (a fix from Matt).
137    o cg2d:
138       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
139       this reduces number of EXCH calls by 2 when using exch2.
140       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
141       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
142    o pkg/thsice:
143       add code for Near Infra-Red albedo (from Jeff)
144       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
145    o ini_model_io:
146       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
147       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
148       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
149    
150    checkpoint61s
151    o pkg/exch2 (exch2_rxN_cube*):
152       remove last BARRIER (no need to synchronise after getting data from shared
153       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
154    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
155      and generate new output (for the 2 tests) using default rotationPeriod.
156    o pkg/exch2:
157      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
158        (was already the case with AUTODIFF_EXCH2 defined)
159      - add bj in exch2 arrays and S/R.
160      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
161        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
162    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
163      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
164        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
165      - verification experiment natl_box.longstep
166    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
167      allow different versions of ifort (8 or 9) and different versions
168       of mpi (mpich or mpich2) to be used with the same optfile.
169      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
170       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
171    o pkg/seaice:
172      fix previous modif (3-level field removed) for old-pickup reading
173    
174    checkpoint61r
175    o pkg/seaice:
176     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
177      1. introduce fields for time step (N-1)
178      2. do not use levels 2 and 3 anymore (but keep them)
179      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
180         includes changes to pkg/thsice/thsice_get_velocity.F,
181         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
182         pkg/obcs/obcs_apply_uvice.F.
183     - completely remove code for leap-frog time stepping for second order
184       advection
185     - adjusted adjoint accordingly;
186       gradient checks have improved by an order of magnitude!
187    
188    checkpoint61q
189    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
190     - the boundary conditions along open boundaries are unclear, because the
191       associated masks are set to zero and are thus treated as closed when
192       applying the slip-boundary conditions.
193     - move initialisation of grid variables from seaice_init_varia to _fixed
194    o adding doc/diags_changes.txt
195    o model/src:
196      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
197       to avoid "_diags" naming if no relation to pkg/diagnostics.
198      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
199       file and only call PLOT_FIELD_XYZ if debugMode=T.
200      remove few PLOT_FIELD_XY calls outside initialisation.
201      remove few unnecessary BARRIER.
202    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
203      of salt_plume package in Southern Ocean
204    o pkg/thsice:
205     - fix hOceMxL in overlap (needed for sea-ice advection);
206       update output of experiment global_ocean.cs32x15.icedyn.
207    o pkg/seaice:
208     - make the (placeholder-)tracer IceAge a little more meaningful
209      by avoiding ridging of age due to convergent ice flow
210     - add diagnostics for surface temperature, atmospheric and oceanic
211       heat flux, and atmospheric and oceanic ice growth
212    
213    checkpoint61p
214    o eesupp (global_max & global_sum):
215     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
216     - remove starting & endding barrier (no longer needed)
217    o pkg/mdsio, writelocal:
218       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
219       (remove the STOP): uses shared buffer IO to store data from all threads
220       and then let master-thread write nThreads tiles.
221    o pkg/mdsio (read/write field):
222     - tiled IO done in 1 piece (all levels at a time);
223     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
224     - multi-threaded: allow to read/write local (non-shared) array
225       (was already working with singleCpuIO ; now works also without);
226       => no longer needs barrier call after reading a file (added inside
227       mds_read/write field).
228     - move barrier calls outside gather/scatter_2d to mds_read/write_field
229    o pkg/obcs/exf
230      - exf_getffieldrec.F: add a few ". _d 0" and
231                            add code to catch the case fldperiod = 0.  
232      - obcs_precribe_read.F: change if statements so that they match
233                              the variable type (_RL)
234      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
235        exf_iprec) as part of namelist EXF_NML_01
236    o pkg/mdsio:
237      - read/write tiled (local) files: read/write 1-level tile chunk at a time
238        (instead of segment of length sNx); expected to speed up tiled IO.
239    o pkg/exch2:
240      - take buffer copy from/to array out of S/R exch2_send/recv into new
241        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
242        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
243      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
244      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
245        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
246        including Topology header file (and common blocks).
247      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
248        remove 2nd exch call in exch2_s3d_rx (no longer needed).
249      - document S/R arg. list (+ update some comments)
250    o pkg/seaice:
251      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
252        temperature and humidity over sea ice based on climatological values.
253      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
254        of LSR (this change is expected to change the results slightly because now
255        it uses slightly difference moduli from the second last LSR solution, but
256        that is more consistent with the stress computations; this part of the code
257        is not tested in the verification experiments)
258      - fix diagnostics for flux of ice in case of B-grid
259      - turn strain rates eij and press into global fields within global
260        common block in SEAICE.h for more straighforward diagnostics
261      - fix diagnostics for principal stress components, press, zeta, eta
262        to give something meaning full
263    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
264      new output (all 4 tests) using default rotationPeriod.
265    o pkg KPP:
266      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
267      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
268        and normal grid from 1 to Nr)
269    o Fix computations of L4rdt in mom_calc_visc.F
270    o eesupp:
271      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
272      should be called before a "stop" if we know that all process are going
273      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
274    
275    checkpoint61o
276    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
277    o model/src/ini_curvilinear_grid.F:
278       compute angleSin/CosC when they are not read from a file
279    o pkg/seaice:
280       add pseudo time stepping for LSOR
281    o pkg/exch2:
282       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
283    o pkg/seaice:
284       Adding separate sea ice albedo, drag coefficients, and HO in Southern
285       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
286    o SingleCpuIO:
287       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
288    o pkg/seaice:
289       put exchanged variable in (local) common block for MPI+Multi-Threads
290       to work (necessary with exch1, and for now with exch2 too).
291    o verification: to get more experiments tested with mpi, mth and mpi+mth,
292      change tiling of:
293       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
294       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
295      update output of exp:
296       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
297       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
298      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
299                       (note: output.txt generated on faulks using only 1 tile)
300    o eesupp & mdsio (SingleCpuIO):
301     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
302       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
303       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
304     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
305     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
306       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
307    o pkg/exch2:
308     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
309       read parameter file "data.exch2" if it exists; otherwise try default regular
310       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
311     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
312       with new code (not to be used, just as a backup solution).
313     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
314       in utils/exch2/input.
315    
316    checkpoint61n
317    o eesupp & mdsio (SingleCpuIO):
318      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
319        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
320        receive real*4 array (instead of real*8) to read/write 32.bit files.
321        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
322         and remove new mapping S/R)
323    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
324      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
325        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
326        when using exch2. Add S/R to map global io-buffer to global model array.
327      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
328    
329    checkpoint61m
330    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
331      and add 3 other S/R for other types (R4,R8,RS).
332      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
333    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
334     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
335     - reduce number of macro definitions (keep only those which are used);
336       can always call directly the corrresponding S/R if needed.
337     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
338       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
339     Fixed wrong type of arg in:
340       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
341       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
342     To fix: global_sum of var in common block is wrong (multi-threaded) in:
343       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
344     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
345    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
346      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
347    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
348    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
349      edges are closed (zero depth); might happen with "blank tiles";
350      for now, disabled if using OBCS.
351    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
352      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
353    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
354      to reduce length of 1.D array print in STDOUT.
355    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
356      + use 48 tiles (16x8): this will allow to test "blank tiles".
357    o start to test MPI + multi-threaded (change testreport to skip tests
358      where number of tiles do not match).
359    o genmake2: add option "-omp" to turn on Open-MP ;
360      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
361    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
362      and keep the original tile numbering. Note: compatible with old
363      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
364    
365    checkpoint61l
366    o Overlaps had been forgotten in calculating ijk keys : fixed
367    o fix cyrus makedepend for gcc 4.4
368    o experiment fizhi-cs-aqualev20:
369      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
370      and generate new output. Note: new output is much closer to the old
371      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
372      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
373    o pkg/fizhi:
374     - change to avoid indices going deliberately over array-bounds
375     - remove unnecessary MPI stuff
376     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
377     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
378       does not go over array-bounds and therefore returns reliable output.
379     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
380       this S/R has 4 output arguments, which are used inside "get_alarm";
381       when it is called with the same variable "ndum" in place of several
382       output arguments, this produces weird side effect inside "get_alarm"
383      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
384       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
385       address) and produces error.
386    o tools/gemake2: (March 27-29 2009)
387      with option "-mpi": link *_mpi files from "MODS" dir (this is what
388      testreport does).
389    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
390    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
391       update lab_sea.lsr & lab_sea.salt_plume results
392    o pkg/seaice:
393      Major overhaul of the LSOR solver: change discretization from original
394      finite differences to finite volume. The old routine is still in the
395      file seaice_lsr.F and can be turned on with the CPP-flag
396      SEAICE_OLD_AND_BAD_DISCRETIZATION
397      Along with this change, the discretization of the strain rates is changed.
398      The same flag turns on the old discretization in seaice_calc_strainrates.F
399      All verification experiments with seaice are affected (except for
400      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
401      results by setting the above flag.
402      Further changes involve changes in defaults:
403      - ALLOW_FLOODING is defined and turned on by default
404      - SEAICEadvSnow = .true. is now the default
405      - SEAICEadvSalt = .true. is now the default
406      - SEAICEadvAge  = .true. is now the default
407      - SEAICE_clipVelocities  = .false. is now the default
408                                         (as per J. Zhang's recommendation)
409      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
410        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
411      - seaice_growth: replace computation of UG by a simple copy from wspeed
412    
413    checkpoint61k
414    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
415      seaice_lsr: fixed a few metric terms,
416                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
417                  add more debugging diagnostics
418      seaice_evp: removed superfluous many metric terms of FV discretization
419                  of stress divergence
420                  affects lab_sea, lab_sea.hb87
421      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
422                  of stress divergence for non-evp solver
423                  (this part is not tested anywhere)
424      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
425                  they were effectively only half slip
426                  affects lab_sea.hb87
427      updated all relevant verification experiments (except lab_sea//output_adm.txt
428        which was left over, but fails at level 7 & 6)
429    
430    checkpoint61j
431    o pkg/seaice: turn a few hard wired parameters into run time parameters
432    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
433      time in seconds as promised by the usints in seaice_monitor and exf_monitor
434    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
435      that are not cubed-sphere grids
436    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
437    o pkg/ctrl:
438      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
439    o non-hydrostatic (calc_gw.F):
440      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
441      update output of exp. global_ocean.cs32x15.viscA4
442    o remove backward compatibility for thetaMin,phiMin
443      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
444    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
445      interpolated wind field not only for curvilineargrid=.true., but also
446      for a rotated grid (rotateGrid=.true.)
447    o pkg/exf: add capability to bypass interpolation for runoff
448      by setting yet another CPP-flag
449    o eesupp/src, B-grid exchange:
450      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
451    o autodiff
452      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
453      allows to switch to single-prec common blocks;
454      corresponding switch occurs in tamc.h, integer isbyte
455      TAF store directivs "byte" and "kind" seem equivalent;
456      Most tamc.h have been updated correspondingly.
457    
458    checkpoint61i
459    o autodiff:
460      fix autodiff_sore/_restore indices for obcs
461      (spotted by I. Hoteit, M. Mazloff)
462    o pkg/autodiff, pkg/ctrl:
463      Add flag to reduce all tapelev I/O to single-prec.
464      In data.ctrl set
465        doSinglePrecTapelev = .TRUE.
466    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
467      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
468    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
469      real fresh water flux (not yet)
470    o pkg/mdsio & rw:
471     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
472     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
473    o pkg/flt:
474     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
475       init_fixed & ini_varia.
476     - clean-up & simplify linear interpolation S/R:
477       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
478     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
479     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
480     - add vert. coordinate & horiz. indices to output files.
481     - change vertical position in initial condition, from index to depth [m].
482     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
483       (easier to get to a curvilinear grid) ; delX,delY no longer used.
484    o pkg/ggl90: a few modifications:
485     - fix bottom boundary condition, and interpolation of KappaE
486       near top and bottom
487     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
488     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
489     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
490    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
491      (maintain temporary backward compatibility, until next checkpoint)
492    
493    checkpoint61h
494    o pkg/diagnostics with "periodic averaging diagnostics":
495      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
496    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
497    o pkg/obcs: fix loop ranges for balancing code
498    o pkg/flt:
499     - improve criteria for finding which tile owns a float.
500     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
501    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
502      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
503      with ocean biogeo)
504    o pkg/flt:
505     - do some cleaning and fix the restart ;
506     - add output.txt in flt_example/results to get this pkg tested.
507    o genmake2: add an EXTENDED_SRC option and flag.
508       for now, cannot be turned on on command line (only through genmake_local)
509    o pkg/mdsio: read/write vector:
510     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
511     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
512       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
513     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
514      (drop to 4 digits matching for grad). But this test does not look very
515      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
516    
517    checkpoint61g
518    o pkg/flt:
519      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
520       + make OPTIONS file more standard.
521      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
522      - fix _BYTESWAPIO CPP-Flag
523      - standard reading of file-parameter "data.flt"
524      - fix argument list of S/R FLT_RESTART
525      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
526    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
527    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
528      a still unfixed compiler/optimization bug
529    
530    checkpoint61f
531    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
532      update results of global_ocean.cs32x15.icedyn test.
533    o move getcon.F from model/src to pkg/fizhi.
534    o pkg/exf: add parameter for extrapolation of temp up to the surface
535       and option to prevent negative evap (in bulk_largeyeager04 only).
536    o Prather Advection scheme: fix tracer conservation for divergent flow
537      (e.g., when using NonLin Free-Surface).
538    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
539    o gmredi (Visbeck-variable-K):
540     - add more parameters to Visbeck-variable-K.
541     - use a 5 points average for dSigmaR in Visbeck-K calculation
542       (more "homogenous": same stencil and same weights as in dSigmaH)
543     - update output of ideal_2D_oce experiment.
544    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
545      (#undef REAL4_IS_SLOW)
546     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
547       coordinate variable
548     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
549       (surface forcing fields), removes some of the functionality
550     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
551     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
552       probably not all: copy _RS surface flux fields to RL field before
553       calling DIAGNOSTICS_FILL
554     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
555       real*4 (CALL EXCH_*_RS) versions.
556     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
557       (generate new output).
558    
559    checkpoint61e
560    o gmredi (Visbeck-variable-K):
561      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
562      - change computation of Visbeck-K where Slope > Smax :        
563        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
564        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
565    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
566      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
567    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
568    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
569      does not become too large (to avoid precision problems in implicit-diffusion
570      solver); update ideal_2D_oce output.
571    o pkg ggl90:
572      - in ggl90_cal.F: compute only one set of visc/diff, used to
573        step forward TKE/T/S/momentum
574      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
575        have Prandlt =1)
576    o gmredi (fm07):
577      - add lower limit on Transition layer thickness + lower limit on 1/lambda
578      - allow to set few more params from data.gmredi
579    o pkg ggl90:
580          - add missing sqrt(2) factor in computation of mixing length
581            scale in ggl90_calc.F
582            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
583    
584    checkpoint61d
585    o adjoint modifs
586      - adapt to new field rhoInSitu
587      - allow to revert from StoreDynVars2D, StoreDynVars3D
588        to individual fields
589        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
590    o store 3-D (in-situ) density in commom block (DYNVARS.h)
591     - save 1 rho computation.
592     - no longer modify T & S inland when using down_slope pkg.
593    o gad_som : allow to switch to SOM advection for T & S without corresponding
594      pickup files (using new S/R: MDS_CHECK4FILE).
595    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
596      (for useSingleCpuIO to work in multi-threaded)
597    o pkg/shelfice:
598     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
599       with SHELFICEtopoFile in data.shelfice
600     - move code for reading ice shelf topography and modifying hFacC into separate
601       subroutines of the shelfice package
602     - separate initialisation of "fixed" and "variable" variables
603     - kTopC is not (yet) replaced by kSurfC, although this is possible
604    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
605    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
606      and rename:
607      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
608      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
609    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
610    
611    checkpoint61c
612    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
613      to add mass source/sink of fluid in the interior (3-D generalisation
614      of oceanic real-fresh water flux).
615    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
616    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
617    o new pkg: down_slope
618      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
619      - presently, modify T & S inland (dwnslp_calc_rho.F).
620        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
621      - implementation for ocean in P-coords not tested.
622      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
623    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
624      (to facilitate conversion of oceanic pkg to p-coordinate).
625    o change FIND_RHO to FIND_RHO_2D :
626      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
627    o new pkg: cheapaml
628    
629    checkpoint61b
630    o exch2:
631      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
632      - no longer depend on the order sequence (N,S,E,W).
633      - 3rd exchange no longer needed (tested with 24 tiles).
634      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
635      - exch_UV_A-grid readily available (but not yet tested).
636      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
637      (both are no longer needed) in exch_uv: no effect in forward run; but
638       get truncation error differences with adjoint exch.
639    o exch2:
640     - change index-bounds storage (moved from target to local tile,
641       more intuitive this way) ; rename/remove some variables.
642     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
643    
644    checkpoint61a
645    o exch2/matlab-topology-generator:
646      fix bug in index bounds for N-S internal exchange (hard to tell if this
647      had any effect on the solution).
648    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
649      is exceeded
650    o testreport: modify syntax of awk, so that it works also with
651      awk, and not only with nawk and gawk
652    
653    checkpoint61
654    o autodiff
655      Change default for TAF usage by removing argument '-nonew_arg'
656      This changes TAF subroutine argument list (ordering of active var.)
657      Omission of this flag leads to incompatibility w.r.t. TAMC
658      To restore TAMC-compatibility, need following modifs:
659      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
660      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
661      Tested TAF version is 1.9.22
662      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
663    
664    checkpoint60
665    --->>> This is the last checkpoint for which generating the adjoint
666    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
667    --->>> by default.
668    --->>> Future checkpoints will ommit this flag by default.
669    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
670    o pkg/grdchk: Add gradient check to etan0 perturbations.
671    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
672    o pkg/autodiff: more flexibility in zeroadj.
673      model/src: modifying do_oceanic_phys.F accordingly.
674    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
675    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
676      special setup of gmredi for which the adjoint is stable
677      enough for parameter optimization.
678    o bridging the gap between eddy stress and GM.
679      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
680          along with a change in CPP option (now ALLOW_EDDYPSI).
681      -> when using GM w/ GM_AdvForm:
682          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
683          is applied either in the tracer Eq. or in momentum Eq.
684          depending on data.gmredi (intro. GM_InMomAsStress).
685      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
686      The key modifications are in model/src/taueddy_external_forcing.F
687      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
688    
689    checkpoint59r
690    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
691      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
692      fix option to read coriolis(@ cell-corner) from files with CS-grid.
693    o pkg/mnc: add some attributes to standard 1D-coordinate variables
694    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
695      mass points, when using mnc for output
696      - add runtime parameter (missing_value, missing_value_int) to override
697        default (which is the value of getcon('UNDEF'))
698    o pkg/mnc: prepare mnc for the actual use of missing values with the
699      diagnostics package: small fix in mnc_cw_readwrite.template and more
700      initialisation of never used fields
701      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
702      versions
703    o pkg/thsice/thsice_ini_vars.F added default initial values so that
704      thermodynamics sea ice solver does not blow up when some initial fields
705      are missing.
706    o move from external_forcing_surf.F to ini_forcing.F
707      the p-coord. hack consisting in using pLoad to set phi0surf ;
708      update output of tutorial_global_oce_in_p (affected @ truncation level).
709    o Freshen up a bit hs94.1x64x5, notably:
710      remove rotationPeriod and tRef=5*0. (adjoint only), and add
711      exactConserv=.TRUE.
712    o pkg/generic_advdiff:
713      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
714      applies to files where Temperature & Salinity 2nd Order moments are used.
715    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
716      this uses a dynamically allocated internal state data structure
717      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
718      and requires a fortran 90 compiler
719    
720    checkpoint59q
721    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
722       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
723    o Refresh tutorial_global_oce_biogeo, notably:
724      - change bathymetry (put back seamounts in ACC, use hFacs)
725      - change EOS (POLY3 --> JMD95Z)
726      - use Bryan-Lewis vertical diffusivity
727      - use multidimensional advection
728      - remove old virtual virtual in dic pkg, now done through ptracer pkg
729      - change a couple of parameters in dic pkg
730    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
731    o pkg/obcs: change default to OBCSfixTopo = .true.,
732      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
733      - replace "debugMode" with "debugLevel .GE. debLevB"
734    o implementation of TAF directives for gchem,cfc,dic
735    o remove "exp5" (replaced by tutorial_deep_convection).
736    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
737      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
738      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
739      --> changes results in exp4, seaice_obcs
740    o tutorial_deep_convection :
741      update the set-up and increase resolution and domain size ; start
742      from pseudo initial conditions = output at t=120mn in order to see
743      something happening when running testreport.
744    o pkg/seaice: add os7mp as an advection scheme
745                  add check for advection schemes
746                  add a flag for restoring T and S underneath sea ice
747    o pkg/my82: add netcdf-support and diagnostics
748    o thsice pkg:
749      - Now hsMax limits snow height by turning it into ice following
750        flooding scheme (and now conserving energy)
751      - Slight rewriting of the formula in thsice_calc_thick.F
752      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
753      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
754    
755    checkpoint59p
756    o gchem / dic / cfc :
757      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
758      - add new parameter files: "data.dic" & "data.cfc" ;
759      - various re-arrangement in initialisation & header file ;
760      - fix tutorial_global_oce_biogeo for multi-threaded test.
761    o pkg/dic: test for "pickup_dic" file when restarting ;
762      if no pickup-file, can restart with a re-initialised pH (same as it did
763      before) providing pickupStrictlyMatch is set to False.
764    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
765      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
766    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
767      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
768    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
769     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
770       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
771    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
772       scheme to use for vorticty-term ;
773     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
774       (with default selectVortScheme, return to original discretisation)
775     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
776    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
777    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
778      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
779      also fix diagnostics VISCAHW & VISCA4W.
780    
781    checkpoint59o
782    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
783    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
784      move a few statemens out the main loop into separate loops
785    o pkg/shelfice:
786      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
787        (kg/m^2/s), does not break tests, because in verification/isomip,
788        rhoConstFresh=rhoConst (by accident)
789      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
790      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
791        new file model/src/seawater.F, so that they are available for all pkgs.
792      - convert potential temperature into in-situ temperature. This changes the
793        isomip tests => update tests
794    o add a flag writePickupAtEnd (default=true) to be able to suppress
795      writing a pickup at the last timestep
796    o tools/mpack-1.6 :
797      - disable automake (not working) and autoconf (not needed).
798      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
799        also cleaner with much less compilation warnings.
800    o pkg/profiles:
801      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
802      (for "less than 32 characters name" compiler requirement)
803    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
804      conditions that have a different sampling frequency than S/T/U/V obcs
805    o pkg/diagnostics (stats-diags):
806      - fix global Min/Max in case 1 processor get only empty tiles
807    o genmake2: replace (4 times)
808         make genmake_tc_1.o >> genmake_warnings 2>&1
809      with
810         COMM="$CC $CFLAGS -c genmake_tc_1.c"
811         echo $COMM >> genmake_warnings
812         $COMM >> genmake_warnings 2>&1
813      to make genmake2 always see the value of CC as specified in the optfile.
814    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
815      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
816      - modify verification advect_cs test to test SOM-advection on CS-grid.
817    o pkg/ctrl:
818      - Rewrite of ctrl_map_ini_ecco.F,
819        introducing a generic routine (ctrl_map_ini_gen.F).
820      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
821    
822    checkpoint59n
823    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
824      number in dedicate array "hdiag":
825      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
826        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
827      - many small changes (integer format) for large number of diagnostics
828      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
829        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
830    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
831      usingSphericalGrid, this allows to define the rotated grid coordinates
832      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
833      geographical coordinates according to the inverse of the rotation defined
834      by the Euler angles, so that Coriolis parameter and online-interpolation by
835      exf works with the geographical coordinates on XC/YC/XG/YG.
836      Naturally, this feature does not work with all packages, so some
837      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
838      profiles), because there the coordinates are assumed to be regular
839      spherical grid coordinates.
840    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
841      - introduce isopycnal diffusion coefficient control.
842    o tools/adjoint_options:
843      - additional control vector components.
844    o pkg/mnc: have mnc create marginally meaning full coordinate variables
845      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
846    o pkg/mypackage:
847      - add example of read/write pickup for state-var ;
848      - add entry points to the main code for state-vars diags & write-pickup.
849    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
850      transitions for useExfYearlyFields
851      - add new subroutine that determines the file to read from for
852        use*YearlyFields = .TRUE. and .FALSE.
853      - add a verification experiment to global_with_exf that tests
854        useExfYearlyFields with USE_EXF_INTERPOLATION defined
855    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
856      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
857      subroutines (which could be generated from a template, because they are
858      almost identical), for now they are included in obcs_prescribe_read.F for
859      simplicity
860    o pkg/exf:
861      - add a little more diagnostic to exf_interp_read (in analogy to
862        mds_read_field, can be turned off with debugLevel < debugLevA=1)
863      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
864        ugly but fast by unrolling short inner loops, inserting a unroll=8
865        directive in routine lagran, and splitting a loop and making do while the
866        outermost loop (the latter requires the intoduction of index arrays)
867    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
868    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
869      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
870    o verification/seaice_obcs: updated for restart test and latest options
871    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
872      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
873      for now this is only available for the C-grid code and also within
874      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
875    
876    checkpoint59m
877    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
878      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
879    o gad_som : fix flux output (& diagnostics) to have same units as other  
880      advection scheme fluxes (was previously multiplied by deltaT).  
881    o added verification/seaice_obcs both to test seaice open boundaries
882      and to provide an example matlab scrpt for generating them
883    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
884    o pkg/salt_plume: clean up salt_plume_frac.F to
885      remove redundancy in PlumeMethod 1 and 4
886    o pkg/kpp: added saltplume diagnostics
887    o pkg/obcs and pkg/seaice:
888      - do not set uice and vice to zero when OB*icefile are unspecified
889      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
890      - moved seaice tracer obcs after call to seaice_growth
891    o pkg/salt_plume: added various options for salt plume depth
892      criterion and for vertical distribution of the salt
893    
894    checkpoint59l
895    o pkg/ptracers: new version of ptracers pickup:
896      read meta file and write only fields which are needed to restart.
897      ( same logic as main pickup file ; also using pickupStrictlyMatch )
898    o pkg/seaice:
899      - add timescale for melting due to warm mixed layer as a means of
900        setting SEAICE_availHeatFrac more conveniently
901      - add a CPP-flag/runtime parameter check for flooding algorithm
902      - reformulated availHeat in seaice_growth.F to be independent of AREA
903    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
904      unit changes
905    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
906    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
907      SX vector computer.
908    o pkg/seaice:
909      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
910        seaice forcing fields can now be read only through pkg/exf
911      - removed some unused halos
912    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
913    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
914      or U/VICE from U/VWIND before computing U/VSTRESS
915    
916    checkpoint59k
917    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
918      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
919    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
920      all experiments pass when compile with un-initialised var. checking option.
921    o added pkg/salt_plume
922    o script to test restart (for now, in MITgcm_contrib/jmc_script)
923    o pkg/seaice: new read/write pickup version.
924      read meta file and write only fields which are needed to restart.
925      ( same logic as main pickup file ; also using pickupStrictlyMatch )
926    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
927    o lab_sea.hb87: modify the domain & update output.hb87.txt :
928      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
929      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
930      process. Fixed here by closing the domain at the Northern boundary.
931    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
932    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
933      a set of consecutive levels in/from a 3-D array.
934    o pkg/ptracers:
935      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
936      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
937    
938    checkpoint59j
939    o in pkgs: dic, obcs, offline, rbcs:
940      standard way to compute coeff. for time interpolation between 2 time reccords
941      which retains full precision (& make results less dependent on compiler).
942      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
943    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
944      packages instead of reading ice cover and wind speed separately
945    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
946     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
947      to allow to compile customized code before the update)
948    o cleaning-up:
949      - fix CPP instruction syntax in pkg/obcs
950      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
951        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
952      - fix some threads issue in IO parts.
953    o pkg/dic:
954      - add tons of "_d 0" (--> much better testreports !)
955       and then update outputs of tutorial_global_oce_biogeo
956    o pkg/mom_fluxform:
957      add a special version of momentum advection intended to conserve momentum
958      next to a bathymetry step or a coastline edge. (default = off = #undef)
959    o new read/write pickup version:
960      - for now, only implemented for main (mdsio) pickup file.
961      - write out only what is needed to restart; merge pickup_nh , pickup_ph
962        and main pickup together.
963      - read meta file; read only what is needed to restart; stop if a field
964        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
965        if it make sense (even if the restart is not perfect).
966      - if no meta file, assume that pickup to read corresponds exactly to
967        a pickup that would currently be written.
968      - read pickup written in the old format (until checkpoint59i) if it
969        recognizes an old meta file (no field-list).
970      - add a meta file in exp. which starts from a pickup: 2 cases:
971        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
972         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
973        b) a meta file describing the content of the associated pickup file
974         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
975    o pkg/mdsio & pkg/rw:
976      - new routine to read a meta file ; new set of routine to read
977        Multiple-fields file (with meta file).
978    o added open boundary conditions capability for seaice
979        HSNOW, HSALT, UICE, and VICE
980    
981    checkpoint59i
982    o adjoint:
983      * fix multiDimAdvection adjoint
984        (partial recomputation problem by TAF for fVerT(:,:,kDown)
985        and comlev1 size definition (maxpass vs. max. number of tracers)
986      * verification/global_ocean.90x45x15 adjoint now tests
987        NLFS and multiDimAdvection using DST3 (=30)
988      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
989    o pkg/kpp: add "_d 0" to real constant (if missing);
990      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
991      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
992    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
993      for internal parameters related to restart process (formerly from PARAMS.h)
994      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
995    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
996      as argument. (only atm2d & obcs write_pickup have not yet been updated)
997    o pkg/monitor:
998      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
999      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
1000      - account for deep Atmosphere factor and density factor (anelastic)
1001    o added open boundary conditions capability for seaice HEFF and AREA
1002  o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)  o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
