4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level
8      transition in checkpoint61r)
9    
10    checkpoint61x
11    o adjoint: adding two new verification experiments
12      * tutorial_global_biogeo: an online dic sensitivity experiment
13        (work with G. Forget)
14      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
15        (an update of the Dutkiewicz et al., 2006 paper)
16      Both use the same CO2FLUX cost function, but different controls
17      Gradient checks look good, but some recomp. could still be traightened out
18      Should add xx_dic control variable to test at some point
19    o model/src:
20      add run-time parameters to check and/or mask initial Temp & Salt
21    o pkg/ptracers:
22      apply zonal filter (if used) to all passive tracers
23    
24    checkpoint61w
25    o adjoint:
26      * update and finish work on adjoint of dic package (G. Forget)
27      * start adjoint of offline package
28      * bug fix for cube-sphere TLM code (active_file_g.F)
29    o tutorial_global_oce_optim:
30      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
31      and add SIZE.h_mpi for MPI testing
32    o pkg autodiff
33     - fix bug in autodiff_restore
34     - make genmake2 remove comments and empty lines from ad_input_code.f in
35       order to reduce file size (new script file remove_comments_sed)
36    o allows to specify vertical profile of vertical viscosity (viscArNr)
37    o pkg autodiff
38      autodiff_ini_model_io: comment out writing of grid information to netcdf
39      files, because at this time the grid fields are a bunch of zeros
40      (this is analogous to ini_mnc_vars.F)
41    o pkg seaice/autodiff:
42     left-over from removing the 3-time-level fields:
43     - small rearrangement of common blocks (SEAICE.h)
44     - fix field declaration in order to get meaningful output in
45       adseaice.*.nc (adcommon.h)
46    o pkg obcs:
47     - go through NH code only if nonHydrostatic=T
48     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
49     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
50       => Update output of experiment seaice_obcs
51     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
52     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
53     - fix restart for useOBCSprescribe + useEXF
54    o pkg ctrl
55     - make obcs as control parameter work also with useSingleCPUio
56     - replace a few sny and snx by Ny and Nx to be consistent with
57       ctrl_set_globfld_x/yz.F
58    o pkg seaice
59     - re-introduce global field frWtrAtm for the case of
60       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
61     - catch the case of an empty filename in seaice_cost_init_fixed.F
62    o pkg ecco:
63     - small bug fixes in the_main_loop
64      . fix order of monitor arguments
65      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
66      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
67        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
68     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
69       imbalance diagnostics for wmean_h/sflux = 0
70     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
71     - catch the case of empty filenames in ecco_cost_init_fixed.F
72       and ecco_readparms.F
73     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
74       to make this statement meaningfull in ecco_cost_weights.F
75    o pkg zonal_filt:
76      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
77      - when using rStar, filter uVel*hFacW instead of uVel
78       (tested without topography: fix a Pb of growing instability with NLFS)
79    o pkg/aim/thsice:
80     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
81      (works as SST restoring)
82    o pkg/thsice:
83     -add specific parameter for salt restoring in slab mixed-layer
84       (by default equal to the temperature restoring)
85    
86    checkpoint61v
87    o pkg/kpp:
88     -add double diffusive contributions as a hack, turned off by default
89      for now, and the code can be excluded with a CPP-flag
90      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
91     -add a verification experiments to "vermix" to test this code
92    o pkg/mom_common:
93      Move computation of length scales to mom_init_fixed.F (avoid recomputation
94      at each time-steps*levels).
95    o pkg/layers:
96      Created a new package for computing volume fluxes in temperature or
97      [not yet implemented] density layers, e.g. for calculating residual
98      overturning circulations.
99    o pkg/diagnostics:
100      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
101    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
102    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
103      To avoid mixing type (RS/RL) of input/output array argument,
104      replace single mixed-type array with a pair from each type (RS/RL).
105    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
106      is now implemented for all pkgs (previously only done for the main pickup)
107    
108    checkpoint61u
109    o pkg/obcs:
110      - change OB?eta from _RS to _RL and put them into a separate commen block
111      - add code to read OB?eta from a file via obcs_prescribe_read: the code
112        compiles and does not destroy any other experiments, the data is read
113        properly, but the code is not tested in actual applications
114    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
115      create a meaningful unit attribute for the time coordinate variable
116    o pkg/ebm: add plenty of missing "_d 0" ;
117       update results of experiment global_ocean_ebm (fwd + adjoint tests)
118      Notes: several pieces of code only works for (very) specific set up
119       (domain size, lat range, etc ...); should be documented & stop if one
120       of those assumptions is not meet.
121    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
122       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
123          and offline_exf_seaice (seaicetd + adjoint).
124    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
125       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
126        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
127    o few changes to pass when compiling with strick checking of arguments
128       across S/R (allow to find few bugs in S/R calls).
129    o pkg/seaice:
130     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
131       2d-fields, for slightly better performance
132    
133    checkpoint61t
134    o pkg/seaice:
135     - remove unused variables in seaice_evp
136     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
137    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
138       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
139       each processor opens a different file (a fix from Matt).
140    o cg2d:
141       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
142       this reduces number of EXCH calls by 2 when using exch2.
143       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
144       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
145    o pkg/thsice:
146       add code for Near Infra-Red albedo (from Jeff)
147       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
148    o ini_model_io:
149       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
150       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
151       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
152    
153    checkpoint61s
154    o pkg/exch2 (exch2_rxN_cube*):
155       remove last BARRIER (no need to synchronise after getting data from shared
156       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
157    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
158      and generate new output (for the 2 tests) using default rotationPeriod.
159    o pkg/exch2:
160      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
161        (was already the case with AUTODIFF_EXCH2 defined)
162      - add bj in exch2 arrays and S/R.
163      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
164        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
165    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
166      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
167        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
168      - verification experiment natl_box.longstep
169    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
170      allow different versions of ifort (8 or 9) and different versions
171       of mpi (mpich or mpich2) to be used with the same optfile.
172      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
173       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
174    o pkg/seaice:
175      fix previous modif (3-level field removed) for old-pickup reading
176    
177    checkpoint61r
178    o pkg/seaice:
179     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
180      1. introduce fields for time step (N-1)
181      2. do not use levels 2 and 3 anymore (but keep them)
182      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
183         includes changes to pkg/thsice/thsice_get_velocity.F,
184         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
185         pkg/obcs/obcs_apply_uvice.F.
186     - completely remove code for leap-frog time stepping for second order
187       advection
188     - adjusted adjoint accordingly;
189       gradient checks have improved by an order of magnitude!
190    
191    checkpoint61q
192    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
193     - the boundary conditions along open boundaries are unclear, because the
194       associated masks are set to zero and are thus treated as closed when
195       applying the slip-boundary conditions.
196     - move initialisation of grid variables from seaice_init_varia to _fixed
197    o adding doc/diags_changes.txt
198    o model/src:
199      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
200       to avoid "_diags" naming if no relation to pkg/diagnostics.
201      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
202       file and only call PLOT_FIELD_XYZ if debugMode=T.
203      remove few PLOT_FIELD_XY calls outside initialisation.
204      remove few unnecessary BARRIER.
205    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
206      of salt_plume package in Southern Ocean
207    o pkg/thsice:
208     - fix hOceMxL in overlap (needed for sea-ice advection);
209       update output of experiment global_ocean.cs32x15.icedyn.
210    o pkg/seaice:
211     - make the (placeholder-)tracer IceAge a little more meaningful
212      by avoiding ridging of age due to convergent ice flow
213     - add diagnostics for surface temperature, atmospheric and oceanic
214       heat flux, and atmospheric and oceanic ice growth
215    
216    checkpoint61p
217    o eesupp (global_max & global_sum):
218     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
219     - remove starting & endding barrier (no longer needed)
220    o pkg/mdsio, writelocal:
221       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
222       (remove the STOP): uses shared buffer IO to store data from all threads
223       and then let master-thread write nThreads tiles.
224    o pkg/mdsio (read/write field):
225     - tiled IO done in 1 piece (all levels at a time);
226     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
227     - multi-threaded: allow to read/write local (non-shared) array
228       (was already working with singleCpuIO ; now works also without);
229       => no longer needs barrier call after reading a file (added inside
230       mds_read/write field).
231     - move barrier calls outside gather/scatter_2d to mds_read/write_field
232    o pkg/obcs/exf
233      - exf_getffieldrec.F: add a few ". _d 0" and
234                            add code to catch the case fldperiod = 0.  
235      - obcs_precribe_read.F: change if statements so that they match
236                              the variable type (_RL)
237      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
238        exf_iprec) as part of namelist EXF_NML_01
239    o pkg/mdsio:
240      - read/write tiled (local) files: read/write 1-level tile chunk at a time
241        (instead of segment of length sNx); expected to speed up tiled IO.
242    o pkg/exch2:
243      - take buffer copy from/to array out of S/R exch2_send/recv into new
244        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
245        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
246      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
247      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
248        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
249        including Topology header file (and common blocks).
250      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
251        remove 2nd exch call in exch2_s3d_rx (no longer needed).
252      - document S/R arg. list (+ update some comments)
253    o pkg/seaice:
254      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
255        temperature and humidity over sea ice based on climatological values.
256      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
257        of LSR (this change is expected to change the results slightly because now
258        it uses slightly difference moduli from the second last LSR solution, but
259        that is more consistent with the stress computations; this part of the code
260        is not tested in the verification experiments)
261      - fix diagnostics for flux of ice in case of B-grid
262      - turn strain rates eij and press into global fields within global
263        common block in SEAICE.h for more straighforward diagnostics
264      - fix diagnostics for principal stress components, press, zeta, eta
265        to give something meaning full
266    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
267      new output (all 4 tests) using default rotationPeriod.
268    o pkg KPP:
269      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
270      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
271        and normal grid from 1 to Nr)
272    o Fix computations of L4rdt in mom_calc_visc.F
273    o eesupp:
274      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
275      should be called before a "stop" if we know that all process are going
276      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
277    
278    checkpoint61o
279    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
280    o model/src/ini_curvilinear_grid.F:
281       compute angleSin/CosC when they are not read from a file
282    o pkg/seaice:
283       add pseudo time stepping for LSOR
284    o pkg/exch2:
285       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
286    o pkg/seaice:
287       Adding separate sea ice albedo, drag coefficients, and HO in Southern
288       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
289    o SingleCpuIO:
290       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
291    o pkg/seaice:
292       put exchanged variable in (local) common block for MPI+Multi-Threads
293       to work (necessary with exch1, and for now with exch2 too).
294    o verification: to get more experiments tested with mpi, mth and mpi+mth,
295      change tiling of:
296       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
297       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
298      update output of exp:
299       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
300       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
301      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
302                       (note: output.txt generated on faulks using only 1 tile)
303    o eesupp & mdsio (SingleCpuIO):
304     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
305       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
306       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
307     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
308     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
309       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
310    o pkg/exch2:
311     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
312       read parameter file "data.exch2" if it exists; otherwise try default regular
313       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
314     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
315       with new code (not to be used, just as a backup solution).
316     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
317       in utils/exch2/input.
318    
319    checkpoint61n
320    o eesupp & mdsio (SingleCpuIO):
321      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
322        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
323        receive real*4 array (instead of real*8) to read/write 32.bit files.
324        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
325         and remove new mapping S/R)
326    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
327      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
328        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
329        when using exch2. Add S/R to map global io-buffer to global model array.
330      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
331    
332    checkpoint61m
333    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
334      and add 3 other S/R for other types (R4,R8,RS).
335      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
336    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
337     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
338     - reduce number of macro definitions (keep only those which are used);
339       can always call directly the corrresponding S/R if needed.
340     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
341       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
342     Fixed wrong type of arg in:
343       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
344       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
345     To fix: global_sum of var in common block is wrong (multi-threaded) in:
346       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
347     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
348    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
349      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
350    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
351    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
352      edges are closed (zero depth); might happen with "blank tiles";
353      for now, disabled if using OBCS.
354    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
355      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
356    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
357      to reduce length of 1.D array print in STDOUT.
358    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
359      + use 48 tiles (16x8): this will allow to test "blank tiles".
360    o start to test MPI + multi-threaded (change testreport to skip tests
361      where number of tiles do not match).
362    o genmake2: add option "-omp" to turn on Open-MP ;
363      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
364    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
365      and keep the original tile numbering. Note: compatible with old
366      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
367    
368    checkpoint61l
369    o Overlaps had been forgotten in calculating ijk keys : fixed
370    o fix cyrus makedepend for gcc 4.4
371    o experiment fizhi-cs-aqualev20:
372      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
373      and generate new output. Note: new output is much closer to the old
374      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
375      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
376    o pkg/fizhi:
377     - change to avoid indices going deliberately over array-bounds
378     - remove unnecessary MPI stuff
379     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
380     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
381       does not go over array-bounds and therefore returns reliable output.
382     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
383       this S/R has 4 output arguments, which are used inside "get_alarm";
384       when it is called with the same variable "ndum" in place of several
385       output arguments, this produces weird side effect inside "get_alarm"
386      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
387       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
388       address) and produces error.
389    o tools/gemake2: (March 27-29 2009)
390      with option "-mpi": link *_mpi files from "MODS" dir (this is what
391      testreport does).
392    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
393    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
394       update lab_sea.lsr & lab_sea.salt_plume results
395    o pkg/seaice:
396      Major overhaul of the LSOR solver: change discretization from original
397      finite differences to finite volume. The old routine is still in the
398      file seaice_lsr.F and can be turned on with the CPP-flag
399      SEAICE_OLD_AND_BAD_DISCRETIZATION
400      Along with this change, the discretization of the strain rates is changed.
401      The same flag turns on the old discretization in seaice_calc_strainrates.F
402      All verification experiments with seaice are affected (except for
403      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
404      results by setting the above flag.
405      Further changes involve changes in defaults:
406      - ALLOW_FLOODING is defined and turned on by default
407      - SEAICEadvSnow = .true. is now the default
408      - SEAICEadvSalt = .true. is now the default
409      - SEAICEadvAge  = .true. is now the default
410      - SEAICE_clipVelocities  = .false. is now the default
411                                         (as per J. Zhang's recommendation)
412      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
413        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
414      - seaice_growth: replace computation of UG by a simple copy from wspeed
415    
416    checkpoint61k
417    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
418      seaice_lsr: fixed a few metric terms,
419                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
420                  add more debugging diagnostics
421      seaice_evp: removed superfluous many metric terms of FV discretization
422                  of stress divergence
423                  affects lab_sea, lab_sea.hb87
424      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
425                  of stress divergence for non-evp solver
426                  (this part is not tested anywhere)
427      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
428                  they were effectively only half slip
429                  affects lab_sea.hb87
430      updated all relevant verification experiments (except lab_sea//output_adm.txt
431        which was left over, but fails at level 7 & 6)
432    
433    checkpoint61j
434    o pkg/seaice: turn a few hard wired parameters into run time parameters
435    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
436      time in seconds as promised by the usints in seaice_monitor and exf_monitor
437    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
438      that are not cubed-sphere grids
439    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
440    o pkg/ctrl:
441      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
442    o non-hydrostatic (calc_gw.F):
443      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
444      update output of exp. global_ocean.cs32x15.viscA4
445    o remove backward compatibility for thetaMin,phiMin
446      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
447    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
448      interpolated wind field not only for curvilineargrid=.true., but also
449      for a rotated grid (rotateGrid=.true.)
450    o pkg/exf: add capability to bypass interpolation for runoff
451      by setting yet another CPP-flag
452    o eesupp/src, B-grid exchange:
453      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
454    o autodiff
455      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
456      allows to switch to single-prec common blocks;
457      corresponding switch occurs in tamc.h, integer isbyte
458      TAF store directivs "byte" and "kind" seem equivalent;
459      Most tamc.h have been updated correspondingly.
460    
461    checkpoint61i
462    o autodiff:
463      fix autodiff_sore/_restore indices for obcs
464      (spotted by I. Hoteit, M. Mazloff)
465    o pkg/autodiff, pkg/ctrl:
466      Add flag to reduce all tapelev I/O to single-prec.
467      In data.ctrl set
468        doSinglePrecTapelev = .TRUE.
469    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
470      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
471    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
472      real fresh water flux (not yet)
473    o pkg/mdsio & rw:
474     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
475     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
476    o pkg/flt:
477     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
478       init_fixed & ini_varia.
479     - clean-up & simplify linear interpolation S/R:
480       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
481     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
482     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
483     - add vert. coordinate & horiz. indices to output files.
484     - change vertical position in initial condition, from index to depth [m].
485     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
486       (easier to get to a curvilinear grid) ; delX,delY no longer used.
487    o pkg/ggl90: a few modifications:
488     - fix bottom boundary condition, and interpolation of KappaE
489       near top and bottom
490     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
491     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
492     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
493    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
494      (maintain temporary backward compatibility, until next checkpoint)
495    
496    checkpoint61h
497    o pkg/diagnostics with "periodic averaging diagnostics":
498      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
499    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
500    o pkg/obcs: fix loop ranges for balancing code
501    o pkg/flt:
502     - improve criteria for finding which tile owns a float.
503     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
504    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
505      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
506      with ocean biogeo)
507    o pkg/flt:
508     - do some cleaning and fix the restart ;
509     - add output.txt in flt_example/results to get this pkg tested.
510    o genmake2: add an EXTENDED_SRC option and flag.
511       for now, cannot be turned on on command line (only through genmake_local)
512    o pkg/mdsio: read/write vector:
513     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
514     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
515       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
516     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
517      (drop to 4 digits matching for grad). But this test does not look very
518      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
519    
520    checkpoint61g
521    o pkg/flt:
522      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
523       + make OPTIONS file more standard.
524      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
525      - fix _BYTESWAPIO CPP-Flag
526      - standard reading of file-parameter "data.flt"
527      - fix argument list of S/R FLT_RESTART
528      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
529    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
530    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
531      a still unfixed compiler/optimization bug
532    
533    checkpoint61f
534    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
535      update results of global_ocean.cs32x15.icedyn test.
536    o move getcon.F from model/src to pkg/fizhi.
537    o pkg/exf: add parameter for extrapolation of temp up to the surface
538       and option to prevent negative evap (in bulk_largeyeager04 only).
539    o Prather Advection scheme: fix tracer conservation for divergent flow
540      (e.g., when using NonLin Free-Surface).
541    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
542    o gmredi (Visbeck-variable-K):
543     - add more parameters to Visbeck-variable-K.
544     - use a 5 points average for dSigmaR in Visbeck-K calculation
545       (more "homogenous": same stencil and same weights as in dSigmaH)
546     - update output of ideal_2D_oce experiment.
547    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
548      (#undef REAL4_IS_SLOW)
549     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
550       coordinate variable
551     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
552       (surface forcing fields), removes some of the functionality
553     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
554     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
555       probably not all: copy _RS surface flux fields to RL field before
556       calling DIAGNOSTICS_FILL
557     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
558       real*4 (CALL EXCH_*_RS) versions.
559     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
560       (generate new output).
561    
562    checkpoint61e
563    o gmredi (Visbeck-variable-K):
564      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
565      - change computation of Visbeck-K where Slope > Smax :        
566        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
567        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
568    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
569      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
570    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
571    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
572      does not become too large (to avoid precision problems in implicit-diffusion
573      solver); update ideal_2D_oce output.
574    o pkg ggl90:
575      - in ggl90_cal.F: compute only one set of visc/diff, used to
576        step forward TKE/T/S/momentum
577      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
578        have Prandlt =1)
579    o gmredi (fm07):
580      - add lower limit on Transition layer thickness + lower limit on 1/lambda
581      - allow to set few more params from data.gmredi
582    o pkg ggl90:
583          - add missing sqrt(2) factor in computation of mixing length
584            scale in ggl90_calc.F
585            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
586    
587    checkpoint61d
588    o adjoint modifs
589      - adapt to new field rhoInSitu
590      - allow to revert from StoreDynVars2D, StoreDynVars3D
591        to individual fields
592        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
593    o store 3-D (in-situ) density in commom block (DYNVARS.h)
594     - save 1 rho computation.
595     - no longer modify T & S inland when using down_slope pkg.
596    o gad_som : allow to switch to SOM advection for T & S without corresponding
597      pickup files (using new S/R: MDS_CHECK4FILE).
598    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
599      (for useSingleCpuIO to work in multi-threaded)
600    o pkg/shelfice:
601     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
602       with SHELFICEtopoFile in data.shelfice
603     - move code for reading ice shelf topography and modifying hFacC into separate
604       subroutines of the shelfice package
605     - separate initialisation of "fixed" and "variable" variables
606     - kTopC is not (yet) replaced by kSurfC, although this is possible
607    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
608    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
609      and rename:
610      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
611      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
612    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
613    
614    checkpoint61c
615    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
616      to add mass source/sink of fluid in the interior (3-D generalisation
617      of oceanic real-fresh water flux).
618    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
619    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
620    o new pkg: down_slope
621      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
622      - presently, modify T & S inland (dwnslp_calc_rho.F).
623        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
624      - implementation for ocean in P-coords not tested.
625      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
626    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
627      (to facilitate conversion of oceanic pkg to p-coordinate).
628    o change FIND_RHO to FIND_RHO_2D :
629      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
630    o new pkg: cheapaml
631    
632    checkpoint61b
633    o exch2:
634      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
635      - no longer depend on the order sequence (N,S,E,W).
636      - 3rd exchange no longer needed (tested with 24 tiles).
637      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
638      - exch_UV_A-grid readily available (but not yet tested).
639      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
640      (both are no longer needed) in exch_uv: no effect in forward run; but
641       get truncation error differences with adjoint exch.
642    o exch2:
643     - change index-bounds storage (moved from target to local tile,
644       more intuitive this way) ; rename/remove some variables.
645     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
646    
647    checkpoint61a
648    o exch2/matlab-topology-generator:
649      fix bug in index bounds for N-S internal exchange (hard to tell if this
650      had any effect on the solution).
651    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
652      is exceeded
653    o testreport: modify syntax of awk, so that it works also with
654      awk, and not only with nawk and gawk
655    
656    checkpoint61
657    o autodiff
658      Change default for TAF usage by removing argument '-nonew_arg'
659      This changes TAF subroutine argument list (ordering of active var.)
660      Omission of this flag leads to incompatibility w.r.t. TAMC
661      To restore TAMC-compatibility, need following modifs:
662      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
663      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
664      Tested TAF version is 1.9.22
665      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
666    
667    checkpoint60
668    --->>> This is the last checkpoint for which generating the adjoint
669    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
670    --->>> by default.
671    --->>> Future checkpoints will ommit this flag by default.
672    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
673    o pkg/grdchk: Add gradient check to etan0 perturbations.
674    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
675    o pkg/autodiff: more flexibility in zeroadj.
676      model/src: modifying do_oceanic_phys.F accordingly.
677    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
678    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
679      special setup of gmredi for which the adjoint is stable
680      enough for parameter optimization.
681    o bridging the gap between eddy stress and GM.
682      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
683          along with a change in CPP option (now ALLOW_EDDYPSI).
684      -> when using GM w/ GM_AdvForm:
685          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
686          is applied either in the tracer Eq. or in momentum Eq.
687          depending on data.gmredi (intro. GM_InMomAsStress).
688      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
689      The key modifications are in model/src/taueddy_external_forcing.F
690      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
691    
692    checkpoint59r
693    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
694      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
695      fix option to read coriolis(@ cell-corner) from files with CS-grid.
696    o pkg/mnc: add some attributes to standard 1D-coordinate variables
697    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
698      mass points, when using mnc for output
699      - add runtime parameter (missing_value, missing_value_int) to override
700        default (which is the value of getcon('UNDEF'))
701    o pkg/mnc: prepare mnc for the actual use of missing values with the
702      diagnostics package: small fix in mnc_cw_readwrite.template and more
703      initialisation of never used fields
704      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
705      versions
706    o pkg/thsice/thsice_ini_vars.F added default initial values so that
707      thermodynamics sea ice solver does not blow up when some initial fields
708      are missing.
709    o move from external_forcing_surf.F to ini_forcing.F
710      the p-coord. hack consisting in using pLoad to set phi0surf ;
711      update output of tutorial_global_oce_in_p (affected @ truncation level).
712    o Freshen up a bit hs94.1x64x5, notably:
713      remove rotationPeriod and tRef=5*0. (adjoint only), and add
714      exactConserv=.TRUE.
715    o pkg/generic_advdiff:
716      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
717      applies to files where Temperature & Salinity 2nd Order moments are used.
718    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
719      this uses a dynamically allocated internal state data structure
720      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
721      and requires a fortran 90 compiler
722    
723    checkpoint59q
724    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
725       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
726    o Refresh tutorial_global_oce_biogeo, notably:
727      - change bathymetry (put back seamounts in ACC, use hFacs)
728      - change EOS (POLY3 --> JMD95Z)
729      - use Bryan-Lewis vertical diffusivity
730      - use multidimensional advection
731      - remove old virtual virtual in dic pkg, now done through ptracer pkg
732      - change a couple of parameters in dic pkg
733    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
734    o pkg/obcs: change default to OBCSfixTopo = .true.,
735      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
736      - replace "debugMode" with "debugLevel .GE. debLevB"
737    o implementation of TAF directives for gchem,cfc,dic
738    o remove "exp5" (replaced by tutorial_deep_convection).
739    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
740      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
741      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
742      --> changes results in exp4, seaice_obcs
743    o tutorial_deep_convection :
744      update the set-up and increase resolution and domain size ; start
745      from pseudo initial conditions = output at t=120mn in order to see
746      something happening when running testreport.
747    o pkg/seaice: add os7mp as an advection scheme
748                  add check for advection schemes
749                  add a flag for restoring T and S underneath sea ice
750    o pkg/my82: add netcdf-support and diagnostics
751    o thsice pkg:
752      - Now hsMax limits snow height by turning it into ice following
753        flooding scheme (and now conserving energy)
754      - Slight rewriting of the formula in thsice_calc_thick.F
755      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
756      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
757    
758    checkpoint59p
759    o gchem / dic / cfc :
760      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
761      - add new parameter files: "data.dic" & "data.cfc" ;
762      - various re-arrangement in initialisation & header file ;
763      - fix tutorial_global_oce_biogeo for multi-threaded test.
764    o pkg/dic: test for "pickup_dic" file when restarting ;
765      if no pickup-file, can restart with a re-initialised pH (same as it did
766      before) providing pickupStrictlyMatch is set to False.
767    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
768      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
769    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
770      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
771    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
772     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
773       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
774    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
775       scheme to use for vorticty-term ;
776     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
777       (with default selectVortScheme, return to original discretisation)
778     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
779    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
780    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
781      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
782      also fix diagnostics VISCAHW & VISCA4W.
783    
784    checkpoint59o
785    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
786    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
787      move a few statemens out the main loop into separate loops
788    o pkg/shelfice:
789      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
790        (kg/m^2/s), does not break tests, because in verification/isomip,
791        rhoConstFresh=rhoConst (by accident)
792      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
793      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
794        new file model/src/seawater.F, so that they are available for all pkgs.
795      - convert potential temperature into in-situ temperature. This changes the
796        isomip tests => update tests
797    o add a flag writePickupAtEnd (default=true) to be able to suppress
798      writing a pickup at the last timestep
799    o tools/mpack-1.6 :
800      - disable automake (not working) and autoconf (not needed).
801      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
802        also cleaner with much less compilation warnings.
803    o pkg/profiles:
804      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
805      (for "less than 32 characters name" compiler requirement)
806    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
807      conditions that have a different sampling frequency than S/T/U/V obcs
808    o pkg/diagnostics (stats-diags):
809      - fix global Min/Max in case 1 processor get only empty tiles
810    o genmake2: replace (4 times)
811         make genmake_tc_1.o >> genmake_warnings 2>&1
812      with
813         COMM="$CC $CFLAGS -c genmake_tc_1.c"
814         echo $COMM >> genmake_warnings
815         $COMM >> genmake_warnings 2>&1
816      to make genmake2 always see the value of CC as specified in the optfile.
817    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
818      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
819      - modify verification advect_cs test to test SOM-advection on CS-grid.
820    o pkg/ctrl:
821      - Rewrite of ctrl_map_ini_ecco.F,
822        introducing a generic routine (ctrl_map_ini_gen.F).
823      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
824    
825    checkpoint59n
826    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
827      number in dedicate array "hdiag":
828      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
829        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
830      - many small changes (integer format) for large number of diagnostics
831      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
832        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
833    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
834      usingSphericalGrid, this allows to define the rotated grid coordinates
835      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
836      geographical coordinates according to the inverse of the rotation defined
837      by the Euler angles, so that Coriolis parameter and online-interpolation by
838      exf works with the geographical coordinates on XC/YC/XG/YG.
839      Naturally, this feature does not work with all packages, so some
840      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
841      profiles), because there the coordinates are assumed to be regular
842      spherical grid coordinates.
843    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
844      - introduce isopycnal diffusion coefficient control.
845    o tools/adjoint_options:
846      - additional control vector components.
847    o pkg/mnc: have mnc create marginally meaning full coordinate variables
848      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
849    o pkg/mypackage:
850      - add example of read/write pickup for state-var ;
851      - add entry points to the main code for state-vars diags & write-pickup.
852    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
853      transitions for useExfYearlyFields
854      - add new subroutine that determines the file to read from for
855        use*YearlyFields = .TRUE. and .FALSE.
856      - add a verification experiment to global_with_exf that tests
857        useExfYearlyFields with USE_EXF_INTERPOLATION defined
858    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
859      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
860      subroutines (which could be generated from a template, because they are
861      almost identical), for now they are included in obcs_prescribe_read.F for
862      simplicity
863    o pkg/exf:
864      - add a little more diagnostic to exf_interp_read (in analogy to
865        mds_read_field, can be turned off with debugLevel < debugLevA=1)
866      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
867        ugly but fast by unrolling short inner loops, inserting a unroll=8
868        directive in routine lagran, and splitting a loop and making do while the
869        outermost loop (the latter requires the intoduction of index arrays)
870    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
871    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
872      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
873    o verification/seaice_obcs: updated for restart test and latest options
874    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
875      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
876      for now this is only available for the C-grid code and also within
877      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
878    
879    checkpoint59m
880    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
881      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
882    o gad_som : fix flux output (& diagnostics) to have same units as other  
883      advection scheme fluxes (was previously multiplied by deltaT).  
884    o added verification/seaice_obcs both to test seaice open boundaries
885      and to provide an example matlab scrpt for generating them
886    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
887    o pkg/salt_plume: clean up salt_plume_frac.F to
888      remove redundancy in PlumeMethod 1 and 4
889    o pkg/kpp: added saltplume diagnostics
890    o pkg/obcs and pkg/seaice:
891      - do not set uice and vice to zero when OB*icefile are unspecified
892      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
893      - moved seaice tracer obcs after call to seaice_growth
894    o pkg/salt_plume: added various options for salt plume depth
895      criterion and for vertical distribution of the salt
896    
897    checkpoint59l
898    o pkg/ptracers: new version of ptracers pickup:
899      read meta file and write only fields which are needed to restart.
900      ( same logic as main pickup file ; also using pickupStrictlyMatch )
901    o pkg/seaice:
902      - add timescale for melting due to warm mixed layer as a means of
903        setting SEAICE_availHeatFrac more conveniently
904      - add a CPP-flag/runtime parameter check for flooding algorithm
905      - reformulated availHeat in seaice_growth.F to be independent of AREA
906    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
907      unit changes
908    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
909    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
910      SX vector computer.
911    o pkg/seaice:
912      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
913        seaice forcing fields can now be read only through pkg/exf
914      - removed some unused halos
915    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
916    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
917      or U/VICE from U/VWIND before computing U/VSTRESS
918    
919    checkpoint59k
920    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
921      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
922    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
923      all experiments pass when compile with un-initialised var. checking option.
924    o added pkg/salt_plume
925    o script to test restart (for now, in MITgcm_contrib/jmc_script)
926    o pkg/seaice: new read/write pickup version.
927      read meta file and write only fields which are needed to restart.
928      ( same logic as main pickup file ; also using pickupStrictlyMatch )
929    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
930    o lab_sea.hb87: modify the domain & update output.hb87.txt :
931      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
932      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
933      process. Fixed here by closing the domain at the Northern boundary.
934    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
935    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
936      a set of consecutive levels in/from a 3-D array.
937    o pkg/ptracers:
938      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
939      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
940    
941    checkpoint59j
942    o in pkgs: dic, obcs, offline, rbcs:
943      standard way to compute coeff. for time interpolation between 2 time reccords
944      which retains full precision (& make results less dependent on compiler).
945      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
946    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
947      packages instead of reading ice cover and wind speed separately
948    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
949     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
950      to allow to compile customized code before the update)
951    o cleaning-up:
952      - fix CPP instruction syntax in pkg/obcs
953      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
954        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
955      - fix some threads issue in IO parts.
956    o pkg/dic:
957      - add tons of "_d 0" (--> much better testreports !)
958       and then update outputs of tutorial_global_oce_biogeo
959    o pkg/mom_fluxform:
960      add a special version of momentum advection intended to conserve momentum
961      next to a bathymetry step or a coastline edge. (default = off = #undef)
962    o new read/write pickup version:
963      - for now, only implemented for main (mdsio) pickup file.
964      - write out only what is needed to restart; merge pickup_nh , pickup_ph
965        and main pickup together.
966      - read meta file; read only what is needed to restart; stop if a field
967        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
968        if it make sense (even if the restart is not perfect).
969      - if no meta file, assume that pickup to read corresponds exactly to
970        a pickup that would currently be written.
971      - read pickup written in the old format (until checkpoint59i) if it
972        recognizes an old meta file (no field-list).
973      - add a meta file in exp. which starts from a pickup: 2 cases:
974        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
975         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
976        b) a meta file describing the content of the associated pickup file
977         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
978    o pkg/mdsio & pkg/rw:
979      - new routine to read a meta file ; new set of routine to read
980        Multiple-fields file (with meta file).
981    o added open boundary conditions capability for seaice
982        HSNOW, HSALT, UICE, and VICE
983    
984    checkpoint59i
985    o adjoint:
986      * fix multiDimAdvection adjoint
987        (partial recomputation problem by TAF for fVerT(:,:,kDown)
988        and comlev1 size definition (maxpass vs. max. number of tracers)
989      * verification/global_ocean.90x45x15 adjoint now tests
990        NLFS and multiDimAdvection using DST3 (=30)
991      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
992    o pkg/kpp: add "_d 0" to real constant (if missing);
993      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
994      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
995    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
996      for internal parameters related to restart process (formerly from PARAMS.h)
997      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
998    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
999      as argument. (only atm2d & obcs write_pickup have not yet been updated)
1000    o pkg/monitor:
1001      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
1002      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
1003      - account for deep Atmosphere factor and density factor (anelastic)
1004    o added open boundary conditions capability for seaice HEFF and AREA
1005    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
1006      thermodynamics
1007      - requires a little reorganization, which affects the testreport results
1008        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
1009        so that now the conservative form is tested
1010      - add a few comments
1011    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
1012    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
1013    o add new diagnostics to seaice: advective, diffusive fluxes (only for
1014      multidim-advection, for scheme 2 they are not filled) and transports,
1015      thermodynamic growth rates
1016    o change units of EmPmR (inside the code, + within coupling interface)
1017      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
1018      Affects results @ truncation level (cg2d match) and update output of
1019       experiments: lab_sea(6), global_ocean.90x40x15(10),
1020      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
1021      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
1022      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
1023      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
1024    
1025    checkpoint59h
1026    o pkg/exf:
1027      - improve vectorization by moving if-statement out of loops in
1028        exf_mapfields, exf_radiation
1029      - exf_bulkformulae.F: introduce 2D fields and vectorize code
1030    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
1031    o testreport:
1032      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
1033        monitor & update offline_exf_seaice exp. output.
1034      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
1035    o pkg/seaice:
1036      - bug fix in the evp solver: boundary conditions were affected be
1037        masking of zMax/zMin (changes results)
1038      - minor bug fix in boundary conditions in seaice_calc_strainrates
1039        (changes results for no_slip)
1040      - seaice_lsr.F: make interpolation of eta dependent on boundaries
1041      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
1042      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
1043        stress formulation and no-slip boundary conditions
1044    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
1045      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
1046    o pkg/seaice: a first HSALT time stepping equation has been checked in
1047    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
1048      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
1049      without requiring DO-IF statements
1050    o pkg/thsice:
1051      use continuous power-law function for partition of energy between lateral
1052      melting/freezing and thinning/thickening ; old code using step function
1053      still available with #undef THSICE_FRACEN_POWERLAW
1054      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
1055    o testreport: change AD testing : check against results/output_adm.txt
1056      using same scripts as for forward test.
1057    
1058    checkpoint59g
1059    o adjoint testing: in preparation for changing testreport:
1060      - output format: cost and grad written on separated lines
1061      - ad output results in directory "results" (instead of "results_ad")
1062    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
1063    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
1064    o pkg/ecco: allow user defined cost function contributions
1065    o testreport:
1066      Allow to choose (per experiment) the list of tested output variables
1067       and the main variable (used to issue a pass/FAIL ) ;
1068      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
1069      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
1070      Also modify printing of summary:
1071       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
1072       b) echo the list of tested variables in the individual summary.txt of
1073          each experiment.
1074    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
1075      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
1076      (but still depend on the tile decompostion of the domain).
1077    o pkg/seaice: change a discretization detail to make the B-grid code
1078      "more symmetric". This change is likely to remove all "ridges/leads" that
1079      where quasi-aligned with the grid in B-grid solutions. It may also be
1080      the solution to the stress coupling issues with the B-grid.
1081    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
1082      remove .cvsignore from input dir. (since testreport no longer run here).
1083    o pkg/thsice:
1084     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
1085     - fix reshaping of sea-ice just after advection:
1086       melt all the ice only if ice-volume is too small.
1087     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
1088       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
1089     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
1090    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
1091      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
1092    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
1093      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
1094      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
1095      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
1096      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
1097      -> update output.txt
1098    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
1099     this affects truncation error: -> update output.txt of exp:
1100      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
1101      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
1102    
1103    checkpoint59f
1104    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
1105    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
1106      a bounded range (in forward mode)
1107    o pkg/ecco, ctrl, autodiff and mom_common:
1108     internal parameter controls, completements of implementations
1109    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
1110    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
1111      (not seem any difference in testing results).
1112    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
1113       at face corners.
1114    o pkg/generic_advdiff:
1115     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
1116      loop range indices for computing vertical advection tendency
1117      and do the calculation in the interior only (no overlap) ;
1118      for now, only implemented for SOM advection (to save CPU time).
1119     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
1120    o exch2 adjoint
1121      First set of changes:
1122      - add exch2 hand-written adjoint templates
1123      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
1124        This will require cleanup in pkg/autodiff/*.F
1125        (changed routines currently kept separate in verif. code/)
1126      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
1127        that used to hide exch2 or cubed-sphere specific code
1128        (commented via 'cph-exch2')
1129    o pkg/seaice
1130      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
1131    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
1132       output of global_ocean.cs32x15.thsice .
1133    
1134    checkpoint59e
1135    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
1136      for B-grid vector (not yet tested) and C-grid vector (<- only used
1137      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
1138    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
1139      (#ifdef ALLOW_SALT_PLUME)
1140    o gather_2d/scatter_2d: removed halo regions
1141    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
1142      scheme and the corresponding test case (under front_relax dir). For now,
1143      only available with Skew-flux form and not yet tested in realistic set-up.
1144      adjoint: store directives updated, but gradient checks deteriorated,
1145      so maybe GM/Redi adjoint is now broken.
1146    o seaice adjoint
1147      * add AREA, HEFF, HSNOW as control variable
1148        (should not change lab_sea results)
1149      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
1150    o pkg/seaice:
1151      * added computation of saltFlux in seaice_growth;
1152        For time being, sea ice salinity is assumed constant
1153        contribution of snow flooding to freshening of sea ice is neglected.
1154        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
1155        defaults to 0.0 in order to maintain backward compatibility.
1156        Typical values for SEAICE_salinity are 4 to 10 g/kg.
1157      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
1158      * added SEAICE_availHeatFrac, which specifies fraction of surface level
1159        heat content used to melt or grow ice
1160      * commented out cap of HICE: it helps keep ice thinner
1161      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
1162      * applied OBCS T/S mask to HEFFM sea ice mask
1163    
1164    checkpoint59d
1165    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
1166     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
1167     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
1168    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
1169     and change default value of parameter "GM_Small_Number";
1170     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
1171       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
1172       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
1173    o pkg/ecco: cost function when applying pkg/smooth to controls
1174    o pkg/ctrl: add forcingPrecond run time parameter
1175    o pkg/seaice:
1176     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
1177     - fix bug in metric terms of u-equation in LSR solver (implicit part),
1178       changes verification/lab_sea
1179     - rearrange implicit part of u-equation in LSR solver to make it easier to
1180       read, understand, and debug. This causes changes at the truncation level.
1181     - fix (serious) bug in the boundary conditions (sign error in the implicit
1182       part) of the LSR solver. Changes all LSR results.
1183     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1184       is initilized with small values - does not change lab_sea results.
1185     - added HsnowFile initialization capability
1186    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1187     initialization of pkg/smooth and application to control vector
1188    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
1189    o dependencies: pkg/profiles requires pkg/cal
1190    o pkg/profiles:
1191     - added option ALLOW_PROFILES_GENERICGRID
1192         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1193         that interpolation information (grid points and coefficients) is provided
1194         within the netcdf input files.
1195         -> sample matlab scripts can be found in MITgcm_contrib/gael
1196         that allow you to prepare netcdf input files.
1197     - also modified: cleaner include statements, cleaner error print statements,
1198       cleaner stops when error, and more tests of the netcdf input files consistency.
1199    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1200    o pkg/seaice:
1201     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1202       requires a new routine: seaice_diagnostics_fill.F
1203     - make sure that seaice does not move if not forced (pressure replacement
1204       method, Hibler and Ip, 1995), changes results
1205     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1206     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1207       It is turned off by default (=-1.), because it changes the results.
1208     - make it possible to read AREA from a file, too.
1209    
1210    checkpoint59c
1211    o add S/R and diagnostics for oceanic mixed-layer depth
1212    o move GMRedi call after all vertical mixing schemes (including KPP)
1213    o pkg/thsice:
1214     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1215      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1216    o pkg/obcs:
1217     - bug fix for balance code
1218    o pkg/seaice:
1219      - allow values of SEAICE_elasticParm > 1
1220      - add new parameter SEAICE_evpTauRelax as an alternative
1221        to SEAICE_elasticParm
1222      - make lsr boundary conditions free slip (by default), changes result
1223      - add code for no slip boundary conditions for lsr
1224      - set minimum of zeta to zero (and not 4e8) (changes results)
1225      - add a cap on AREA after advecting AREA if seaice_growth is not called
1226    o change calculation of Visbeck K:
1227      - no longer depend on tapering scheme; instead, compute slope (limited
1228        by GM_maxSlope). this is equivalent to what was comuted before with
1229        clipping or linear tappering.
1230      - fix vertical averaging (wrong by 1/2 level)
1231      - leave the old version (but will not be maintained) within
1232        #ifdef OLD_VISBECK_CALC / #endif
1233      - update output of exp. ideal_2D_oce
1234    o change error catch in calc_r_star to improve vectorization
1235    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1236      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1237    o adjoint:
1238      Re-organized adjoint checkpointing according to Matt Mazloff
1239      (but with modifs/completions/cleanups)
1240      Storing is now bundled into large arrays to optimized I/O
1241      (and second step in cleanup of the_main_loop)
1242    
1243    checkpoint59b
1244    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1245      - export/import (between ocean & coupler) fields needed for ocean DIC.
1246    o pkg/seaice:
1247      - get rid of three more exchanges seaice_calc_viscosities (required
1248        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1249      - bug fix in seaice_ocean_stress (update of lab_sea required)
1250      - reduce loop boundaries to necessary minimum also in seaice_evp
1251      - go back to the old way of computing deltaC/Z as the adjoint likes that
1252        better
1253    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1254      passive tracer to an Age Tracer) + update output.txt
1255    o pkg/exf:
1256      - implement A-grid / C-grid selection for wind-stress input files.
1257      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1258      for now, in exf_bulk_largeyeager04.F only :
1259      - change implementation for case where windspeed + 2. components wind-stress
1260        are read-in. AND use rhoConstFresh to convert evap.
1261    o pkg/seaice:
1262      - use correct EXCH_UV for wind-forcing (on A-grid).
1263      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1264        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1265    o pkg/exf:
1266      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1267      EXF_INTERPOLATION:
1268      - merge global_with_exf/code version of exf_interp_read.F
1269        to the main code ;
1270      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1271        reading the file ; Important: This options needs to be defined to recover
1272        previous code.
1273        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1274      - no longer loose real*8 precision along the way when using exf_iprec=64.
1275    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1276      - change discretisation of evp-solver in order to avoid another exchange
1277        (changes lab_sea) and clean up a little
1278      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1279        help the adjoint (this also changes the results slightly)
1280      - add a few "_d 0" where they had been missing in seaice_evp.F
1281      - cleaning up: remove unused seaice_calc_rhs.F
1282    o pkg/exf: some cleaning-up:
1283      - change various "constants" into runtime parameters
1284      - cleaned-up Large&Yeager04 routine which should eventually
1285        replace exf_bulkformulae.F (changed names of S/R and CPP)
1286        and merged various ALLOW_ATM_WIND options
1287     only used with thsice pkg (in thsice_get_exf.F):
1288      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1289        which are used when useStabilityFct_overIce=TRUE (= the default)
1290      - change default values of ice & snow emissivity and scale downward LW
1291        by ice & snow emissivity.
1292    o pkg/thsice:
1293     fix few little problems, in thsice_calc_thickn.F:
1294      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1295      - melt only laterally if hIce < hThinIce (as the comments say)
1296      and in thsice_extend.F:
1297      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1298      - start to form ice as soon as the minimum ice-volume is reachable.
1299     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1300      and cpl_aim+ocn
1301    o pkg/kpp
1302     - move computation of surface related input fields to KPP into a new
1303       subroutine kpp_forcing_surf.F
1304     - remove wrong (within bi,bj loops) EXCH calls.
1305     - little cleaning (add argument myThid in last position, cvs header ...)
1306     - for now, fix conservation problem by exchanging KPPviscAz (may not
1307       be the best fix)
1308    o pkg/seaice
1309     - check for inconsistent evp parameter/cpp-flag combination
1310     - remove leftover errIO flat for obsolete name list error handling
1311    o OpenAD
1312     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1313    
1314    checkpoint59a
1315    o pkg/seaice: some parameter clarifications and a little bit of clean up
1316    o pkg/thsice: rename run-time parameters:
1317       himin       -> hIceMin
1318       himin0      -> hThinIce
1319       hihig       -> hThickIce
1320       i0          -> i0swFrac
1321       transCoef   -> bMeltCoef
1322       frac_energy -> fracMelting
1323      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1324       with default values (for now) that do not change the results.
1325      remove old version of thsice vars advection in pkg/seaice.
1326    o in FFIELDS.h:
1327      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1328      - make pLoad & sIceLoad always available (but still only used if
1329         ATMOSPHERIC_LOADING is #define).
1330    o pkg/kpp: replaced _KPP_RL with _RL
1331    o bug fixes for vertical diffusivity computations when both KPP and
1332        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1333        are no longer updating the vertical diffusivity array
1334        (passed as argument) but are (re-) setting those arrays.
1335    o pkg/seaice: fix bug in evp solver, while doing that
1336      - change (improve?) discretization of stress computations for both
1337        cgrid-lsr and evp solver
1338      - add a new routine to compute strain rates
1339      - the above changes lab_sea results
1340      - add no slip conditions for evp solver (off by default), lsr-version
1341        may follow
1342      - fix exchange for shear at Z-points (does not change lab_sea)
1343      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1344        (to force the user to pick a time step since there is not "safe" way
1345        of choosing it)
1346      - add principal stress diagnostics
1347      - rearrange fields for evp a little to avoid having to call a: too many
1348        exchanges and b: exchanges for stress trensor components which we do
1349        not have.
1350      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1351        of evp, complete rewrite for lsr case (latter is does not yet work
1352        in all cases)
1353    o pkg/kpp: add code to have mixing in shelf ice caverns
1354      - add myThid to all kpp routines (long overdue)
1355    
1356    checkpoint59
1357    o pkg/exf:
1358      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1359        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1360      - move exf header files from lower_case.h to UPPER_CASE.h ;
1361        add missing cvs Header & Name
1362      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1363      - add namelist param. selectStressGridPosition, exf_monFreq
1364      - retire many _CLIM routines, and remove data.exf_clim
1365        + params moved to data.exf
1366        + climsst, climsss now handled by exf_set_gen, i.e.
1367          climss?period=0 refers to constant field,
1368          climss?period=-12 to monthly forcing
1369      - split up namelists in data.exf
1370    o pkg/seaice:
1371      - remove seaice_exch and seaice_exch_uv
1372      - remove superfluous exchange of theta
1373      - add myThid to seaice_budget_ocean/ice
1374      - add new interface for atmospheric wind forcing (C-grid only)
1375        + new routine
1376        + two new field (taux, tauy for stress over ice)
1377        + removed one global field (DAIRN) for C-grid case only
1378    o pkg/thsise
1379      - 2nd set of modifs for thsice adjoint in conjunction with exf
1380    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1381    
1382    checkpoint58y_post
1383    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1384      vertical diffusivity, similar to that in MOM4; turned on using
1385      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1386      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1387    o Added capability for 3D specification of background vertical diffusion
1388      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1389      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1390      "data" file that contains the 3D vertical diffusivity coefficients.
1391    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1392      - add code within pkg thsice to advect & diffuse sea-ice fields
1393      similar to (and will replace) what has been added in  seaice_advdiff.F,
1394      but: - conserving Mass, Heat & Salt.
1395           - better when using non-linear advection scheme (not yet fully tested)
1396           - can also be used in atmospheric set-up (for now, only the diffusion).
1397    
1398    checkpoint58x_post
1399    o IO option for global-file compact format:
1400      - add options when generating topology (utils/exch2/matlab-topology-generator)
1401      - add I/O capability (pkg/mdsio).
1402      - adapt utils/matlab/rdmds.m to read this format.
1403      for now long-line format not yet supported by pkg/mdsio (& exch2).
1404    o shelfice: add a few diagnostics
1405    
1406    checkpoint58w_post
1407    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1408      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1409      (and replace horiVertRatio in NH code).
1410      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1411                         and tutorial_plume_on_slope (sensitive to truncation)
1412    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1413      directly to drive seaice model (C-grid only)
1414    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1415     - reintroduce computation of wind from stress,
1416     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1417       mass points to avoid tau = 0
1418     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1419    o rdmnc.m: make it work with "global" files created with gluemnc
1420    o rdmnc.m : some improvements in dealing with singleton dimension
1421      (tested on all testreport mnc output files).
1422    o genmake2: disable pkg/profiles if netcdf test fails.
1423    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1424    o move call to cal_readparms up to make calendar parameters/variable available
1425      to all packages
1426    
1427    checkpoint58v_post
1428    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1429      useDynP_inEos_Zc tested.
1430    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1431    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1432      and portions thereof.  See read_cs.txt for description and examples.
1433    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1434      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1435      following the great-circle arc between those 2 points.
1436    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1437      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1438    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1439     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1440     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1441     - still needs work (not working with some options ; efficiency to improve)
1442       and serious testing.
1443     - use this scheme for temperature & salinity in 2 advection test exp.:
1444       advect_xy & advect_xz, respectively.
1445    
1446    checkpoint58u_post
1447    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1448    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1449    o testreport: add option "-skipdir" to skip some test.
1450    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1451      momentum calculation.
1452    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1453    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1454      remove checkpoint.F and the_correction_step.F (no longer used);
1455      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1456    o add option (linFSConserveTr) to correct for tracer source/sink due to
1457      Linear Free surface
1458    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1459    o pkg/thsice: fix reading mnc-pickups
1460    
1461    checkpoint58t_post
1462    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1463    o pkg/mdsio:
1464     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1465       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1466       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1467     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1468     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1469       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1470     - new S/R (to replace MDSWRITEMETA), which allows to write more
1471       informations (variable names, time ...) to meta files.
1472     - modify rdmds.m to give back the meta file content.
1473    o pkg/diagnostics: change vertical interpolation to be safer, and more
1474       flexible (define p-levels to interpolate to in data.diagnostics);
1475      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1476       diagnostic pointer.
1477    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1478    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1479    o fix multi-category seaice:
1480     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1481       SEAICE_MULTICATEGORY
1482     - fix short wave heat flux
1483    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1484       and allow to use EVP solver. Change forward lab_sea: test both EVP
1485       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1486    o Initial check-in of lab_sea adjoint
1487      (very similar to natl_box_adjoint/code_seaice)
1488      * used C-grid and EVP solver
1489      * used KPP, GM/Redi
1490      * uses inAdExact=.TRUE.
1491      * gradient checks fail for both ADM and TLM
1492        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1493        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1494        issue is related to forward mismatch between g77 an ifort
1495    o pkg/seaice: overhaul of thermodynamics
1496     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1497     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1498     - move a few global fields out of SEAICE.h into seaice_growth.F and
1499       make them 2D (FICE/QNETO/ ...)
1500     - remove FO (it is the same as QNETO)
1501     - introduce a few local fields to avoid modifying external fields such
1502       as atemp, etc.
1503    
1504    checkpoint58s_post
1505    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1506      changed exf_set_gen.F so that
1507        genperiod=0 means input file is one time-constant field and
1508        genperiod=-12 means input file contains 12 monthly means
1509    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1510      this affects truncation error ; generate new output file for exp. which
1511      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1512        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1513        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1514        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1515        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1516        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1517    o start implementation of deep-atmosphere and anelastic formulation
1518    o verification: remove 2nd copy of input files and use script "prepare_run"
1519      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1520    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1521    o profiles: fix for multithreaded case
1522    
1523    o diagnostics: rename few diags:
1524      s/'PRESSURE'/'RCENTER '/g
1525      s/'TICE    '/'oceFreez'/g
1526      s/'TAUX    '/'oceTAUX '/g
1527      s/'TAUY    '/'oceTAUY '/g
1528      s/'SWFLUX  '/'oceQsw  '/g
1529      s/DIFx/DFxE/g
1530      s/DIFy/DFyE/g
1531      and add few ocean-forcing diagnostics:
1532      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1533    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1534      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1535      as actual snow thickness.  It now refers everywhere to effective snow
1536      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1537    
1538    checkpoint58r_post
1539    o modifications to pkg/seaice/growth.F, which change results of
1540      lab_sea experiment: fixes pertain to melting snow over open water, to
1541      masking EVAP under sea ice, and to using the correct AREA variable for
1542      computations of EVAP, PRECIP, HSNOW, and GHEFF
1543    o add ability to read bathy, salt, and theta using MNC (off by def)
1544    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1545      both are turned off by default and do no change any results
1546    o seaice advection with pkg/thsice: a step toward the use of non-linear
1547      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1548    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1549      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1550      in natl_box (affects results @ truncation level: update output.txt)
1551    o multi-threading and IO:
1552      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1553      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1554        (needed to work with SingleCpuIO): tested in all verif. exp.
1555    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1556      affects the results (but none of the verification test uses this scheme).
1557    o Adding some pkg/diagnostics capability to pkg/seaice
1558      (will certainly be subject to changes)
1559    o ctrl: adding new control variables:
1560      lwflux, lwdown, evap, snowprecip, apressure, runoff
1561    
1562    checkpoint58q_post
1563    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1564      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1565      high_res_cube configuration by 4% on Columbia.
1566  o clean-up multi-threaded problems (reported by debugger tcheck on ACES);  o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1567    add (in global_with_exf/code) a version of EXF_INTERP_READ without    add (in global_with_exf/code) a version of EXF_INTERP_READ without
