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);
1567      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1568      dynamical allocation (seems to work in multi-threaded).
1569    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1570      single CPU io) so that TAF does not have to see EESUPPORT.h
1571    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1572    
1573    checkpoint58p_post
1574    o obcs: stop if obcs is used with useCDscheme = .true.
1575    o shelfice:
1576     - fix a sign error so that no slip at shelfice interface works
1577     - remove stop for combination non-hydrostatic code and shelfice. That does
1578       not mean, that the results are correct, but at least they are numerically
1579       stable
1580    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1581    o added adjoint exch routined for all exch*3d* routines
1582      and updated flow directives
1583    
1584    checkpoint58o_post
1585    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1586      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1587    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1588      and clean-up reading/writing of pickup files.
1589    o fix local version of read/write pickup (NH part) in rotating_tank/code
1590    o simplify EXCH interface:
1591     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1592     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1593    o added the regrid package
1594    o shelfice:
1595     - add a simple boundary layer scheme to reduce noise
1596     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1597    
1598    checkpoint58n_post
1599    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1600       local variable (not in common block).
1601    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1602      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1603      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1604        to work with SingleCpuIO.
1605    o add "_d 0" to real constant of pkg/cfc subroutines ;
1606       update exp. cfc_exemple & tutorial_cfc_offline output files.
1607    o multi-threading and IO:
1608      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1609        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1610      - barrier before and after reading.
1611      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1612      - avoid using MDS_WRITELOCAL for LAND pkg output.
1613      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1614        common-block variables ; Allows multi-threading with master-thread IO.
1615    o change default MAX_NO_THREADS from 32 to 4 ;
1616      and stop cleanly when MAX_NO_THREADS is too small.
1617    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1618    
1619    checkpoint58m_post
1620    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1621       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1622    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1623       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1624       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1625    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1626        add MITgcm_tutorials (= code + all the tutorials)
1627    o ecco, option to compute cost for total ssh (mean+anom)
1628    o consistent with addition of ptracer and ssh in pkg/profiles
1629    o profiles: adding ptracer and ssh
1630    o testreport: change multi-test output-file name
1631      (from output.txt.{name} to output.{name}.txt)
1632    o profiles: now ok for mutli-tiles case
1633    o seaice: add 4 parameters for different advection schemes for area,
1634      (effective) seaice thickness, enthalphy, and snow height. Their default
1635      is the standard parameter SEAICEadvScheme
1636    o calc_gw:
1637     - add cosFacU in zonal viscous flux (harmonic.visc.).
1638     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1639       of tutorial_plume_on_slope.
1640    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1641    o calc_gw: true flux-form, account for horizontal grid spacing.
1642      update rotating_tank results, but not plume_on_slope (affected at
1643      truncation level, 11 digits).
1644    
1645    checkpoint58l_post
1646    o calc_gw:
1647     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1648     - remove side-drag for now (need to fix it); update plume_on_slope results.
1649     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1650    o commit code to make SST/SSS weights spatially variable
1651      (based on either variable in-situ or variable initial T/S weights)
1652    o pkg/ecco:
1653      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1654        now based on horizontally varying weights wthetaLev, wsaltLev
1655      * cost_averagesflags now returns year indices in addition to day, month
1656      * sflux balance is performed on annual basis
1657        (sflxumm, sfluxmm2, bal_sfluxmm)
1658      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1659        including separate counting and multipliers
1660    o pkg/rbcs
1661      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1662    
1663    checkpoint58k_post
1664    o testreport:
1665     - always build in dir. "build" (if not there, mkdir build instead of building
1666       & running in input)
1667     - run in dir run (if it exists), in build otherwise.
1668     - call prepare_run (if input/prepare_run exists)
1669     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1670    o pkg/exf modifications to interpolation and rotation routines for more
1671       reasonable treatment of North Pole singularity: for tracers North Pole
1672       value is set to northernmost zonal-mean value, for zonal velocity it is
1673       set to zero, and for meridional velocity it is set to northernmost value.
1674    o pkg/exf/exf_check_range.F
1675     - add tile index to diagnostics and move stop statement to the very
1676       end of the routine.
1677    o pkg/diagnostics: (diagnostics_main_init.F)
1678      define title of isomorphic variables according to the current config.
1679    o pkg/thsice with pkg/seaice dynamics:
1680    - fix domain of computation (interior only, required for exf) and do exchanges
1681    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1682    o towards a standard way of dealing with multi-threading in MONITOR
1683      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1684    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1685       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1686    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1687    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1688    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1689       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1690    o tracer advection:
1691     - clean-up and simplify calc_common_factors.F
1692     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1693       advection subroutine (but still not used within DST advection S/R)
1694    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1695    
1696    checkpoint58j_post
1697    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1698      from file (collects calls previously in FORWARD_STEP)
1699    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1700    o adjoint store dir. adjusted accordingly
1701    o genmake2
1702      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1703    
1704    checkpoint58i_post
1705    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1706      on wind stress (SEAICEstressFactor defaults to 1.)
1707    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1708      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1709    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1710      on CS-grid: no longer loosing mass.
1711    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1712    o pkg/ggl90: fix sloppy output and fix a bug
1713    o pkg/seaice: added SEAICEuseEVPpickup parameter
1714      - Set to false in order to start EVP solver with
1715        non-EVP pickup files when using SEAICEuseEVP
1716      - fix sign error in diffusion in seaice_calc_rhs
1717    
1718    checkpoint58h_post
1719    * Modifications for bottom topography control
1720      o replace hFacC by _hFacC at various places
1721      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1722      o add non-self-adjoint cg2d_nsa
1723      o update autodiff support routines
1724      o re-initialise hfac after ctrl_depth_ini
1725      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1726    * Adding verification for 5x5 box (4-layer) bottom topography control
1727    
1728    checkpoint58g_post
1729    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1730       used for mean seasonal cycle, mean diurnal cycle); add an example
1731       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1732    o pkg/ggl90:
1733      - add parameter (minimum surface kinetic energy)
1734      - fix bug (avoiding division by zero)
1735    o couple pkg/thsice to pkg/seaice:
1736      - modify advection in seaice to accomodate new scalar fields to be advected
1737      - only muliDimAdection scheme work with seaice/thsice
1738      - mapping of thsice-variables to seaice-variables, back and forth
1739      - does not break the verification experiments, but does not give the
1740        desired results either
1741    o pkg/seaice
1742      - make (default) second order advection a bit less confusing?
1743    
1744    checkpoint58f_post
1745    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1746      to pkg/seaice):
1747      - new routines thsice_map_exf and thsice_get_exf provide the interface
1748      - add an additional formal parameter to thsice_solve4temp
1749    o pkg/exf:
1750      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1751      - correct Stefan-Boltzmann constant
1752      - new parameter for longwave surface emittance
1753      - separate some stuff from exf_bulkformulae into new routines  
1754        exf_radiation, exf_wind
1755      - add new parameters and constants: longwave emissivity for ocean, ice
1756        and snow, evaporation parameters over ice
1757      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1758        either wind from stress or stress from wind
1759    o pkg/thSIce:
1760    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1761    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1762       and THSICE_CALC_THICKN
1763    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1764    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1765      to make debugging easier.
1766    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1767    o pkg/bulk_force:
1768      - clean-up comments and parameters ;
1769      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1770    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1771      generate new output for test-experiment: aim.5l_cs.thSI
1772    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1773      testreport accordingly
1774    
1775    checkpoint58e_post
1776    o SEAICE_CGRID adjoint done
1777    o R_STAR adjoint implemented.
1778      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1779      * need to sort out init. of h0facc, etc.
1780    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1781      to be able to use it in pure forward.
1782    
1783    checkpoint58d_post
1784    o upgrade simple test-experiment to tutorial example:
1785     step.1: duplicate the experiment and (step.2) will remove the old copy.
1786      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1787      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1788      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1789      tutorial_global_oce_biogeo    <- copy of dic_example
1790      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1791      tutorial_plume_on_slope       <- copy of plume_on_slope
1792      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1793      tutorial_global_oce_optim     <- empty for now (David ?)
1794      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1795     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1796    o correct a sign problem in cost_scat.F
1797    o obcs and ptracers: fix boundary conditions for advections schemes
1798      with larger stencil
1799    o thsice adjoint: start
1800    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1801      completeness
1802    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1803      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1804    o ptracers adjoint:
1805      * avoid extensive recomputatations
1806      * fix missing re-init. of gptr (missed by TAF)
1807    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1808      me to turn off the excessive output to STDOUT that this package produces
1809    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1810      and add those terms in Vector-Invariant formulation.
1811    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1812      if the control period (xx_hfluxperiod etc) is 0
1813    o in profiles pkg, clean routines and fix details
1814    o in ecco pkg, reading ssh data:
1815      fix problem in case the model does not start at iter0=0
1816    o fix mnc-pickup/restart for ptracers
1817    o new package prifiles:
1818      code to compute profile-based cost by Gael Forget
1819      (modifs in ecco, ctrl, autodiff)
1820    o Benign bug fix in initialization (spotted by M. Mazloff) of
1821      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1822    
1823    checkpoint58c_post
1824    o adjoint: finish NLFS adjoint and provide reference output in
1825      verification/global_ocean.90x40x15/results_ad_nlfs
1826    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1827      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1828      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1829      with SEAICE_CGRID defined.
1830    o move calendarDumps from "data" to "data.cal" and clean-up the code
1831      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1832    o add useEXF & useCAL flags (for now, set in hard-coded way)
1833    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1834      (were missing in NH mode, and wrong in quasihydrostatic mode).
1835      waiting for Chris updated version of calc_gw to add those CALLs.
1836    o fix bug in quasihydrostatic S/R ;
1837      add a test for this option: global_ocean.90x40x15.qshyd
1838    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1839      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1840    o add on/off flag useOffLine for package OFFLINE
1841    o seaice:
1842      - modify advection so that it works also on the C-grid
1843      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1844        problem in multi-tile runs with C-grid
1845      - add flags for clipping ice velocities and/or masking solver forcing
1846      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1847        C-grid solver
1848      - added a few comments to seaice_diffusion.F
1849      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1850        are now exclusive)
1851      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1852        required re-ordering the code a little:
1853       + make DAIRN global variable (defined in SEAICE)
1854       + move computation of the viscosities eta and zeta into a new separate
1855         routine (because I need to recompute them in seaice_ocean_stress.F)
1856    
1857    checkpoint58b_post
1858    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1859      update output.txt of exp. aim.5l_cs.thSI
1860    o various mnc cleanups and improvements:
1861      + shrink lookup tables by factor of ~4
1862      + better error reporting when running out of lookup space
1863      + able to handle longer path/file names (up to 500 chars)
1864    o adjoint:
1865      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1866      - TBD: "hidden" mom_vecinv recomp. in dynamics
1867    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1868     (allow to differentiate between forcing components using new integer flags:
1869      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1870     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1871    o ecco
1872      - enable trend removal from SSH anomaly obs.
1873    o adjoint
1874      - a fix for PmEpR when #undef EXACT_CONSERV
1875      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1876      - try to fix "hidden" recomp. in forward_step for NLFS
1877        (NLFS seems broken sometimes after I checked it in)
1878    o seaice:
1879     - add c-grid version of the dynamic solver:
1880       + three new routines that are the c-grid substitute lsr, dynsolver
1881         and ostres
1882       + put a few fields that were local to dynsolver into global common
1883         blocks, so that I can move the computation of stresses etc into
1884         seaice_lsr (saves coding but may break the adjoint).
1885     - replace more hardwired parameters by runtime parameters
1886     - add ice masks that mask the rhs of the implicit solvers where there
1887       is no ice (commented out in seaice_dynsolver, because i am not sure
1888       if this works properly), eventually this should replace the clipping
1889       of ice velocities in seaice_dynsolver to +/-40cm/s.
1890    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1891      include it only where its needed
1892    o move balancing of fluxes before the call of external_forcing_surf
1893    o seaice:
1894      - correct units of turning angles (now they are really in degrees)
1895      - move computation of GWATX/Y out of main routine into dynsolver
1896      - initialize GWATX/Y in seaice_init
1897    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1898      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1899    o seaice: add runtime flags for turning angles (default to zero)
1900    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1901      and trend from exf forcing and ctrl control adjustments
1902    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1903      (since checkpoint57x_post)
1904    o change the default rotation period to 86164.s = the Earth rotation
1905    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1906      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1907    o seaice advection: add code for choosing between the default (2nd order
1908      central differences) and multiDim advection schemes provided by
1909      pkg/generic_advdiff
1910    o seaice:
1911      - removed all references to SEAICE_GRID.h fields from
1912        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1913        (cubed-sphere configuration will change a little)
1914      - grid computations in seaice_init are obsolete now.
1915      - cleaned up code a little so that is easier to read (hopefully).
1916      - added new (better?) discretizations of default advection and diffusion
1917        (turn on with SEAICEuseFluxForm)
1918      - replace 1 in 3d global fields by kSurface in growth.F
1919      
1920    checkpoint58a_post
1921    o seaice:
1922      - bug fix in advect.F
1923    o shelfice:
1924      - separate shelfice load anomaly from pload (breaks with time
1925        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1926        Its default is 0., but it may be computed more cleverly from (unknown)
1927        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1928        done offline. A good approximation of the pressure load anomaly is
1929        necessary to avoid large initial adjustment processes underneath
1930        deep-reaching shelfice.
1931      - small fix in ISOMIP shelfice_thermodynamics
1932      - add more sophisticated thermodynamics of Hellmer (1989), this is
1933        now the default
1934      - give a few constants more intuitive names
1935    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1936      if bulk formulae are used in long integration (especially EmPmR). Turn
1937      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1938      if balancePrintMean, the imbalance that is substracted is printed to
1939      STDOUT.
1940    o fix bug (typo) in obcs_apply_eta.F
1941    o add a new package shelfice which enables us to model the circulation
1942      underneath shelf-ice with draughts of hundreds of meters.
1943     - works
1944     - to do: + include improved thermodynamics
1945              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1946                instead of new field kTopC
1947              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1948                instead of new field R_shelfIce and new code in ini_depth.F
1949                and ini_mask_etc.F?
1950              + adjust vertical mixing schemes?
1951    o seaice pkg:
1952     - add a cpp-flag to include a simple formula for a salinity dependent
1953       freezing point of sea water at the surface
1954     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1955       meridional stresses are now different (and hopefully correct)
1956    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1957       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1958       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1959    o pkg/diagnostics: add options and parameters for regional-statistics
1960       diagnostics ; define regions by reading a region-mask from a file
1961       (might add other options later)
1962    o pkg/bulk_force:
1963     - add option and parameters to use AIM surface-flux formulae.
1964     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1965       others forcing fields (defined in PARM05, parameter file "data") are loaded
1966       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1967     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1968     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1969     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1970       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1971     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1972    
1973    checkpoint58
1974    o add "--embed-source" option to genmake2 which, when the supporting
1975      tools can be compiled (as determined by genmake2) will turn on the
1976      embed_files package which then embeds the entire MITgcm source code
1977      (*.[fFhc] + Makefile) used for the build within the executable
1978      - requested by CNH but off by default
1979      - adds a paltry <9MB to the mitgcmuv executable in most cases
1980      - only writes the output when useEMBEDSRC in eedata is true
1981    o clean up 3-dim. relaxation codes:
1982      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1983      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1984      * Thanks to Tom Haine for testing!
1985    
1986    checkpoint57z_post
1987    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1988      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1989    o fix the pickup behavior for obcs in combination with ptracers
1990    o fix a bug in ptracers_external_fields_load
1991    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1992      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1993    o transfered surface NH pressure to eta field (if exactConserv).
1994    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1995         and update lab_sea output.txt file.
1996    o completing 3-dim. relaxation code: additional term
1997         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1998      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1999      * At compile time, in "EXF_OPTIONS.h" set
2000          #define  ALLOW_CLIMTEMP_RELAXATION
2001          #define  ALLOW_CLIMSALT_RELAXATION
2002      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
2003          tauThetaClimRelax3Dim = 15552000.0,
2004          tauSaltClimRelax3Dim  = 15552000.0,
2005      * 3 cases:
2006          1) Use a constant-in-time 3-dim. field
2007          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
2008          3) Real-time relax. to time-evolving prescribed field
2009    o Adding Laplacian-type smoothness constraint on
2010      initial and boundary (forcing) controls (ic, bc)
2011      * enable at compile-time via
2012        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
2013      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
2014      * Absolute scale somewhat unclear so far
2015      * no area weighting was included since no other cost term does so far
2016    
2017    checkpoint57y_post
2018    First step for a NLFS adjoint
2019    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
2020    o new init. routines for calc_r_star, calc_surf_dr
2021    o still need to deal with ini_masks_etc
2022    o testreport seemed happy
2023    checkpoint57y_pre
2024    
2025    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
2026    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
2027    o add new offset feature to offline pkg (plus minor cleanup)
2028    o cfc fixes for final year of integration
2029    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
2030      be in GCHEM_OPTIONS).
2031    
2032    checkpoint57x_post
2033    o fix testreport Pb in multiple test experiment.
2034    o cleanup our namelist syntax in verification:
2035      - make it more F95 standards compliant (some work still needed)
2036      - allows the vast majority of our tests to work with gfortran
2037    o Non-Hydrostatic:
2038     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
2039     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
2040    o Allow to apply AB on T,S rather than on AB(gT,gS):
2041     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
2042     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
2043       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
2044     - need a "clever" read_pickup to restart from the other AB formulation
2045    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
2046    o remove some unused variables (reduces number of compiler warnings)
2047    o adjoint
2048      * Disable useVariableViscosity for adjoint for time being
2049        (there are a number of extensive recomputations)
2050      * Initialize certain variables needed for adjoint
2051    
2052    checkpoint57w_post
2053    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
2054                 fix the singleCpuIO RS version of MDSWRITEFIELD
2055       and add a WARNING if using globalFiles=T with multi-processors.
2056    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
2057      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
2058    o tracer advection scheme:
2059      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
2060       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
2061       was not very convenient).
2062      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
2063       (further tests needed for the implicit DST & Flux-Limiter schemes).
2064    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
2065      and sRef for convenience, handy, when you want to initialize
2066      ptracers in a large domain with a constant non-zero value. Also,
2067      untangle ptracers_init.F a little.
2068    
2069    checkpoint57v_post
2070    o change dome exp. to use variable viscosity in side-drag terms.
2071    o remove all the files from the cfc_offline test since they are now
2072      incorporated into tutorial_cfc_offline which has been producing
2073      identical results for a few days of testing
2074    o add new parameter: sideDragFactor to enable half-slip-side BC
2075      and change side-drag S/R to use viscosity from mom_calc_visc
2076      (can switch back by setting sideDragFactor=0.); affects results at
2077      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
2078       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
2079    o vorticity & strain are now computed without masking, to account for
2080      no-slip-side BC in variable viscosity calculation ; mask is applied
2081      anyway later on, before computing advection/coriolis terms.
2082    o modify exp4 to test new obcs support for reading from external files
2083      and for passive tracers
2084    o fix behavior of ptracers_monitor when monitor output is written to a
2085      netcdf-file; still not independent of monitor.F (writes in the same
2086      file).
2087    o change default value of tRef (put a uniform, meaningful value for ocean
2088      & atmos) and initialize sRef (was missing, as Martin mentioned).
2089    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
2090      to be proportional to enstrophy dissipation length.  Thus,
2091       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
2092      This is now consistent with Smagorinsky and with the manual.
2093    
2094    checkpoint57u_post
2095    o OBCS and PTRACERS: add open boundary support for passive tracers
2096      - either use homogenous (pseudo) v.Neumann conditions or prescribe
2097        OB-values from file; this is not different from the way theta and salinity
2098        are treated
2099      - however, Orlanski-radiation conditions are not supported, and the model
2100        will stop if you use pTracers and Orlanski at the same time.
2101      - beefed up the rountine obcs_external_fields_load: now only those open
2102        boundary values are overwritten with values from files for which there
2103        are really files, otherwise the OB-fields remain untouched. This makes
2104        it possible to use different OBs at different ends of the domain (as
2105        with EXF)
2106    o reduce number of exch calls in shap_filt (s2).
2107    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
2108      truncation level) 4/5 MLAdjust test results (11&12 digits match).
2109    
2110    checkpoint57t_post
2111    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
2112    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
2113      same truncation, independent of the face number: affects affects several
2114      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
2115    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
2116      note that biharmonic viscosity + no-slip was not tested in any experiment.
2117    o fix bug in non-linear free-surf side-drag ; generate new output for
2118      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
2119    o make mnc honor the writeBinaryPrec flag for most kinds of output
2120    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
2121    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
2122      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
2123    o add brackets in multi-terms sum to get same truncation, independent of
2124      the face number (manage to get exactly same value of gU,gV at the cs-edge)
2125      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
2126    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
2127      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
2128      a maximum grid-scale Reynolds number.  Also, changes all length calculations
2129      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
2130      Suggested values of viscosity parameters found in mom_calc_visc.
2131      Many new viscosity diagnostics available.
2132    
2133    checkpoint57s_post
2134    o Add clearing-house for viscosity calculations, mom_calc_visc and
2135      correct numerous bugs in LeithD and Smagorinsky discretizations.  
2136      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
2137      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
2138      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
2139      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
2140      The Strain-Tension form is now called with useStrainTensonVisc=.true.
2141      ViscAhStrain and viscAhTension are now retired.
2142    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
2143    o In response to JMC's bug report, genmake2 now ignores any soft-links
2144      that it finds in the *current* directory when searching for files.
2145      Soft-links found in any other source directories will still work as
2146      they did before.
2147    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
2148      a C routine to unlimit the stack size
2149    o mnc-ify pkg/aim snapshot vars
2150    o mnc-ify pkg/land as requested by Daniel
2151    o various changes to mnc including:
2152      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
2153      - output can now be grouped so that all files within a group
2154          change the ITER portion of their names in lock-step together
2155      - can now read ("global") PER-FACE (in addition to PER-TILE) files
2156          and works with both EXCH1 and EXCH2 (but needs more testing)
2157      - writing works for all verification test cases w/ g77 on Linux
2158    
2159    checkpoint57r_post
2160    o make MNC variable initialization happen earlier
2161    o add diagnostics for (almost) each term of the momentum Eq.
2162    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
2163    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
2164    o remove MINIMAL_TAVE_OUTPUT option ;
2165      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
2166    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
2167      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
2168    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
2169    o add time-dependent SST, SSS control
2170    o cost terms in ecco/ modularized (new cost_generic.F)
2171    o cost_averages routines are modularized (new cost_averagesgeneric.F)
2172    o new infrastructure for seaice model vs. obs misfits in seaice/
2173      * driver from the_main_loop.F is seaice_cost_driver.F
2174      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
2175      * gradient check in Exp. 6a of natl_box_adjoint/
2176    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
2177      (see README file)
2178    
2179    checkpoint57q_post
2180    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
2181    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
2182      - bug was reported by Jean-Michel and Ian Fenty
2183    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
2184      update exp. cpl_aim+ocn output.
2185    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
2186      Needed for high-res. runs with large global files
2187      to be able to limit tapelev size
2188    o Changed some tests for adjoint:
2189      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
2190      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
2191      * global_ocean.90x40x15/ back to default 3-level checkpointing
2192    o Modifications to enable scripted COMMON to MODULE conversion
2193      * verification/OpenAD/code/ has necessary scripts and description;
2194      * converts, compiles and runs successfully;
2195    
2196    checkpoint57p_post
2197    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
2198    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
2199      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
2200    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
2201    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
2202      (was already the case for dissipation with mom_vecinv,
2203       and also the case for grad.PhiHyd when staggered-timeStep)
2204      This will allow to put dissipation out-off the AB time-stepping.
2205     Unfortunately, affects truncation error. Update output of exp. that "fails"
2206      (cg2d matching number) and leave the others for later: front_relax(10),
2207      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
2208      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
2209    
2210    checkpoint57o_post
2211    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
2212      (2) its ready to be documented during the 20050801 DocFest
2213    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
2214      for ideal_2D_oce and lab_sea on linux_ia32_g77
2215    o set to #undef CTRL_SET_OLD_MAXCVARS_30
2216      in global1x1_tot/code_seaice_adj to access indices 32, 33
2217      (worth another tag)
2218    
2219    checkpoint57n_post
2220    o adding precip control xx_precip 32
2221    o adding swflux control xx_swflux 33
2222    o Replacing 10 forcing penalty cost routines by 1 generic.
2223    o Implementing partitioning in time-mean and variable adjustment
2224      for atmos. state.
2225    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
2226    o in natl_box_adjoint:
2227      * updated exp 1 to 10
2228        (but does not have time-mean vs. variable split results yet)
2229    o updated global1x1/*_seaice_adj/
2230      to incorporate latest changes
2231    o enable useSingleCpuIO for mdsio vector routines
2232      (applies in particular to tapelev I/O)
2233    o removed inefficient K-loop in all active_file*control*.F
2234    
2235    checkpoint57m_post
2236    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
2237      and advect_cs (use EXCH-2 and standard cs-32 grid files).
2238    o pkg/exch2: filling of face-corner halo regions is optional
2239      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
2240    
2241    checkpoint57l_post
2242     tag before updating tutorials (pre-release-2)
2243    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
2244       for output and interpolation of input fields onto model grid)
2245    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
2246       Affects results of exp. rotating_tank ; update output.txt.
2247    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
2248          and taking the square quantity and/or using a fraction-weight field.
2249    o fix aim_diagnostics_init.F mate numbers.
2250    o add mnc output capability to diagnostics/diagstat and update
2251      our cvsignore files for the ACSII output generated
2252    
2253    checkpoint57k_post
2254    o lab_sea now uses diagnostics package and provides a suite of
2255      new EXF diagnostics output.
2256    
2257    checkpoint57j_post
2258    o exf
2259      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
2260        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
2261        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
2262      * extended diagnostics output
2263        - now includes all EXF variables
2264        - hs, hl moved to common block
2265        - separate S/R for diagnostics, called after ctrl vector is added
2266        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
2267        - EXFqnet contains true Qnet (i.e. includes qsw)
2268      * updated verif. lab_sea, global_with_exf
2269      * Rearranging hflux (exf_mapfields -> exf_getforcing)
2270        to ensure that diagnostics sees a true EXFqnet
2271    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
2272    o diagnostics pkg: change pointers so that 1 diagnostic can be used
2273      several times with different frequencies.
2274    o mnc-ify the thsice package as requested by Daniel Enderton
2275      - the monitor--MNC output needs work
2276      - many attributes need to be added (most are currently blank)
2277    o mnc-ify theaim_v23 package as requested by Daniel Enderton
2278      - many attributes need to be added (most are currently blank)
2279    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
2280    o add Sadourny like discretization to the 4th.O vorticity advection scheme
2281    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
2282      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
2283         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
2284    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
2285     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
2286    
2287    checkpoint57i_post
2288    o Diagnostics package was changed: diagnostic allocation is now deactivated
2289      by setting an empty file name in the namelist (used to be by setting 0 frequency)
2290    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
2291      add 1rst Order upwind vertical Shear.
2292    o add a quick fix for A/B checkpointing in OFFLINE mode
2293    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
2294      end-run around the C/Fortran linking horror in eesup/src/timers.F
2295    o added pkg/runclock: allows user to terminate run based on wall clock
2296    o added non-hydrostatic scaling parameter: nh_am2
2297    o pkg/my82: futile attempt to make results compiler-independent by adding
2298      some "_d 0", etc. no effect.
2299    o for mnc output, fill the 'T' coordinate var with myTime and create a
2300      separate 'iter' variable for iteration count
2301    o pkg/diagnostics:
2302      add new capability: output of Global/Regional & per-level statistics ;
2303      tested against monitor output (including land & thSIce) on various exp.
2304    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
2305    
2306    checkpoint57h_done
2307      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
2308      data.diagnostics, data.gchem, data.ptracers) is done.
2309    
2310    o pkg/diagnostics: prepare for Global/Regional statistics.
2311      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
2312    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
2313      and rename it: DIFFERENT_MULTIPLE
2314    
2315    checkpoint57h_post
2316    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
2317    o pkg/diagnostics: change output frequency, now in seconds (instead
2318      of Nb of iterations). This requires to change data.diagnostics.
2319    checkpoint57h_pre
2320    
2321    o in mnc, let the user create the output dir if both mnc_outdir_date
2322      and mnc_outdir_num are false
2323    o add fflags() to pkg/diagnostics which allows one to specify, on a
2324      per-file basis, the file precision [default behavior is unchanged]
2325    o added diagnostics to pkg/kpp, including computation of mixed layer
2326      depth based on a temperature/density criterion
2327    o updated verification/natl_box to test the new pkg/kpp diagnostics
2328    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
2329    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
2330    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
2331      not mnc -- this mistake was found by JMC and is now corrected
2332    
2333    checkpoint57g_post
2334    o add Adams-Bashforth 3rd Order time stepping:
2335      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
2336      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
2337    checkpoint57g_pre
2338    
2339    o make lambda[Theta,Salt]ClimRelax spatially varying
2340      (default remains spatially uniform constant based on tau)
2341    o added new control variables
2342      * init. uVel, vVel, etanN
2343      * lambda[Theta,Salt]ClimRelax
2344    o separate masks used for ctrl_pack/unpack 'from write_grid' output
2345      (suggested by G. Forget)
2346    
2347    checkpoint57f_post
2348    o add parameter "baseTime" = model base time = time at iteration zero
2349      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
2350      account for baseTime shift
2351    o move Coriolis arrays from PARAMS.h to GRID.h
2352    checkpoint57f_pre
2353    
2354    o mnc-ifying the seaice package
2355    o introduced an alternative length scale calculation for use in the limiting
2356      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
2357    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
2358    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
2359      as well as grad(vort3).  Made it compatible with both approximate form
2360      for the cubed sphere and full form of these gradients.  Added flag
2361      useFullLeith to select between approximate and full form.  
2362    o add "d0" in getcon.F to reduce differences between compilers/platforms
2363      update output.txt of exp. fizhi-gridalt-hs
2364    o change port_rand funtion to allow to set the seed.
2365    o fix obscure MNC bug involving conversion between reals and integers
2366      - it caused no problems with certain (eg. gcc, ifc) compilers but the
2367        new version is now more standards-compliant
2368    o adjoint-related modifications
2369      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
2370      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
2371      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
2372    
2373    checkpoint57e_post
2374    o Adding eddy stress controls a la Ferreira et al.
2375    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
2376    
2377    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
2378      update output.txt of exp. fizhi-gridalt-hs
2379    o add more "Z" dimensions and associated coordinate vars to MNC
2380    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
2381    o parameter calendarDumps: when set, approximate months (30-31 days) and years
2382      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
2383      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
2384      months and years.  Requires pkg/cal.
2385    o diagnostics: add pickup functionality
2386      - off by default for backwards compatibility
2387      - current version only uses MDSIO -- MNC will be added
2388    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
2389    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
2390    
2391    checkpoint57d_post
2392    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
2393    o modify verification/ideal_2D_oce so that it tests the creation of mnc
2394      output from the diagnostics package
2395    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
2396    o make genmake2 more portable by using ".$FS" instead of ".f" for more
2397      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
2398    o add coordinate variables to the MNC output from the diagnostics package
2399    o change MNC-flags default value: true when useMNC=TRUE
2400    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
2401      the ability (off by default) to read the grid information using MNC
2402    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
2403    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
2404    o do snap-shot diagnostics at the middle of the time-interval (instead of
2405      at the end).
2406    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
2407      new test for AIM with thSIce + slab-ocean
2408    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
2409    o move state variable diagnostics to the beginning of the time step ;
2410      (note: still needs some work specially for snap-shot diagnostics)
2411      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
2412    
2413    checkpoint57c_post
2414    o Change testing option (-ieee) to get closer agreement between g77 & ifort
2415    o generate new output.txt files on faulks with g77 & the new -ieee option
2416    checkpoint57c_pre
2417    
2418    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
2419      update output.txt of exp. global_ocean.90x40x15
2420    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
2421      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
2422    o add saltFlux(+File) forcing capability with periodicExternalForcing
2423    o allow to use pkg diagnostics for GM-Redi & ThSIce output
2424    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
2425    o improvements for the MNC output from DIAGNOSTICS:
2426      - correct handling of the unlimitied dimension
2427      - all dims now have associated coordinate variables
2428      - variables located at U, V, and Corner ("Z") points are now written
2429        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
2430        *all* data points are output
2431    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
2432    o added pkg/seaice/seaice_monitor.F
2433    o mdsio_readfield.F can now read files visible only to master MPI process.
2434    o pkg/seaice: some test code for ice-modified ocean stress
2435    o exf_getffields interpolation defaults to bilinear for all scalar forcing
2436      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
2437      spurious negative numbers for precipitation and humidity.  Will cause
2438      some small numerical differences for integrations using pkg/exf/exf_interp.F.
2439    o pkg/ctrl/
2440      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
2441        May be enabled via doPackDiag
2442      *  introduce z-scaling of
2443         + gradient (doZscalePack) and
2444         + control (doZscaleUnpack)
2445    o pkg/mdsio/
2446      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
2447      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
2448    
2449    checkpoint57b_post
2450    o simplify options in diagnostics_fill arguments (remove weird combinations)
2451    o fix MNC coordinate variables so that they now contain per-face index
2452      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
2453      general, EXCH2 grids are only aligned to a "local" coordinate system
2454    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
2455    o Implement instantaneous output within pkg diagnostics:
2456      setting a negative frequency in data.diagnostics produces
2457     "snap-shot" output (as opposed to time-average if freq > 0)
2458    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
2459      NOTE: change ptracer diagnostics name: use 2 characters to work with
2460            more than 9 tracers. Add also diagnostics of advect & diffus flux.
2461    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
2462      becomes the coordinate variable for the 'T' dimension
2463    o add CF-style coordinate variables to MNC
2464      - just a first cut:  numbers are meaningless on the cubesphere and
2465        missing along the T axis but otherwise it works!
2466    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
2467    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
2468    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
2469      this is based directly on what the model compute, so that the content of
2470      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
2471    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
2472    o clean up build options files for SunOS, in particular
2473      - remove -traditional from xmakedepend
2474      - change -xarch=v9 to -xarch=native for f77
2475      - restore use of make (not gmake)
2476      - add CC=gcc if using g77
2477    o changes per discussion of AM, JMC, & EH3 today:
2478      - move redundant "grid" variables out of "state" -- in preparation of
2479        creating proper CF-style coordinate variables and in recognition
2480        that any/all grid variables can be easily copied (eg. w/NCO) from
2481        the grid files into any of the other NetCDF files
2482      - *always* output grid variables with MDSIO (this will eventually be
2483        changed)
2484      - output MNC grid file if useMNC is true
2485    o every instance of _END_MASTER() has been found and replaced with
2486      _END_MASTER( myThid ) in order to satisfy certain picky Sun
2487      preprocessors
2488    o re-arrange diagnostics pkg initialisation:
2489     - allow each package to extend the available diagnostics list
2490     - add some checking and fix small problems (multi-threaded, ...)
2491     - new S/R diagnostics_fill (replace fill_diagnostics):
2492       look through the short list of active diag. (instead of the long list)
2493       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
2494    
2495    checkpoint57a_post
2496    o this set of changes restores TAMC compatibility
2497      tested for global_ocean.90x40x15 adjoint on trough
2498      (what a pain)
2499    
2500    checkpoint57a_pre
2501    o some modifs in tools/build_options for sunos
2502    o call ctrl_pack for ctrl at end for optimcycle=0
2503    
2504    checkpoint57
2505    o add horizontal bi-harmonic viscosity for vertical velocity
2506      - new parameter viscA4W (defaults to viscA4)
2507      - affects only non-hydrostatic code
2508      - to be done: no-slip lateral boundary conditions
2509    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
2510    o implement Implicit Vertical advection for pTracers
2511    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
2512      (implemented also for implicit vertical diffusion & advection)
2513    o OBCS: extend application of tracer open boundary conditions
2514      to a strip beyond the boundary of width Olx/Oly
2515    o add call monitor to TAF set of required calls (flow directives)
2516      and include in natl_box_adjoint
2517    o untangle a few ifdefs related to cost, ctrl, autodiff
2518      untangel a few ALLOW_ECCO_OPTIMIZATION
2519    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
2520      (theta2, salt2 in ecco_cost_weights)
2521    
2522    checkpoint56c_post
2523    o OBCS as control variables
2524      - update ctrl_ad_diff.list, obcs_ad_diff.list
2525      - remove balance of obcs controls from default
2526      - fix index bug nobcs in ctrl_init
2527      - fix dummy fields filen in ctrl_pack
2528      - add dummy weights for obcs
2529    o lsopt: comment out fort.94 output
2530    o optim:
2531      - remove unnecessary header files
2532      - adjusted namelists
2533      - add xerbla.F to Makefile
2534    o exf:
2535      - multiple modifications of exf_check_range
2536      - unit change in exf_init_runoff from [m/year] to [m/s]
2537    o mdsio:
2538      - i/o-vector change debugLevel from debLevA to debLevB
2539    
2540    checkpoint56b_post
2541    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
2542      is called from DO_THE_MODEL_IO
2543      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
2544      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
2545      - clean up PTRACERS_WRITE_TIMEAVE a little
2546    o add another verification experiment that tests both the cfc-pkg and
2547      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
2548      reactive tendencies treated inline with regular timestepping
2549    o testreport previously did a lousy job of comparing small numbers, so
2550      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
2551      implemented in the little c-progam tmp_cmpnum.c which is embedded in
2552      testreport.
2553    o ptracers_monitor: bug fix for MPI
2554    
2555    checkpoint56a_post
2556    o GCHEM: finish reorganizating the package
2557      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
2558        (introduces another 3D-array for each passive tracer, but only if
2559        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
2560        gchemTendency is not needed because the timestep is done separately)
2561      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
2562      - GCHEM is now---more or less cleanly---separate from PTRACERS
2563      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
2564        so clear to me how that should be done in a general way.
2565    o CFC: improve formatting of output in CFC_ATMOS
2566    o PTRACERS:
2567      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
2568        that ALL experiments with ptracers enable can be checked. This makes
2569        GCHEM_MONITOR obsolete.
2570      - include a runtime parameter PTRACERS_monitorFreq that defaults to
2571        monitorFreq
2572      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
2573    o add PTRACERS (PTR0[1-5]) to testreport output
2574    o exf_check_range:
2575      * default changed to .TRUE.
2576      * will check values for niter0 if debLevA, every timestep if debLevB
2577      * STOP in exf_check_range if 'out of range'
2578      * range chosen generous to allow for potential extema
2579      TBD: a version with stricter range
2580           permitted range would be runtime parameters
2581    o GMredi:
2582      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
2583      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
2584      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
2585    o GCHEM:
2586      - move call to GCHEM_FORCING_SEP, so that it is now called before
2587        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
2588      - introduced a useGCHEM runtime flag and applied it everywhere.
2589      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
2590        this flag is now only visible within GCHEM-pkg routines.
2591      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
2592        be replaced by a 3D array that is computed before thermodynamics; for
2593        this, the tracer ID iTracer had to be included into the parameter list
2594        of ptracers_forcing
2595      - set up forward_step to call gchem_forcing, that will replace
2596        gchem_forcing_int in ptracers_forcing
2597      - cleaning up
2598    o small cleaning of exch2: remove files that are also in eesupp/src
2599    
2600    checkpoint56
2601    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
2602    o mnc: cleanup "full" files--fixes out-of-memory problem
2603    o ECCO-GODAE
2604      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
2605      * fully merged and updated from SIO code
2606        windstress sign change affects
2607        - exf_inscal_[u/v]stress
2608        - sign of xx_tau[u/v] adjustments
2609        - signs in cost_scat
2610      * ctrl_get_gen: avoid update of tau[u/v] for first few days
2611      * natl_box_adjoint updated and compressed
2612      * 2-level checkpoint switch added
2613        (tested in EXP. 1 of natl_box_adjoint)
2614      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
2615    o SVD
2616      * first complete, non-hacked version for SVD calculations
2617      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
2618        performed via direct access files admtlm_vector.it????
2619        (via ctrl_[un]pack)
2620      * optimcycle is used for ARPACK iteration counter
2621        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
2622      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
2623        and add linear transforms where necessary
2624      * controls are initial/final SST, SSS (can be extended; need to check
2625        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
2626    o mdsio: filename info to both stderr, stdout
2627    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
2628      from sign change
2629    
2630    checkpoint55j_post
2631    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
2632      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
2633    o add consistent build directories and .cvsignore files to verification
2634    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
2635    o make all subroutines 30 or less characters in length for certain older
2636      compilers to work (a thorough search only turns up two routines in
2637      pkg/ptracers)
2638    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
2639      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
2640    
2641    checkpoint55i_post
2642    o change arrays for total vertical diffusivity (2.D if explicit,
2643      3.D if implicit) ; each ptracer uses its own background value.
2644    o added mnc/NetCDF output capability to ocn_compon_interf
2645      - added bits to verification/cpl_aim+ocn so that it can run on
2646        ITRDA and other clusters without the mpirun "-wd" option
2647    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
2648      configuration
2649    o give MNC the ability to create additional files rather than
2650      exceeding a specified file size limit "MNC_MAX_FILESIZE"
2651      - the default is just less than 2GB which is a practical limit
2652        on many systems
2653    o Compute the non-local term using either KPP vertical diffusivity (=default)
2654       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
2655    
2656    checkpoint55h_post
2657    o add verification test "vermix"
2658    o remove all the *_ioinc flags and replace with the single global
2659      outputTypesInclusive flag
2660    o allow to set a vertical profile of vertical diffusivity for T & S
2661    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
2662    o useMNC moved from data.mnc to data.pkg
2663    
2664    checkpoint55g_post
2665    o Renaming carbon AD experiments to comply with testreport conventions
2666    o Updating adjoint of Held-Suarez hs94.1x64x5
2667    o Fixing directives for non-ECCO forward_step, after ECCO directives
2668      have been fixed to avoid recomp. of do_oceanic_phys
2669      Works well for global_ocean.90x40x15,
2670      but recomp. issue remains for carbon
2671    o Updating adjoint output for natl_box_adjoint after
2672      pkg/ecco has been modified (see taga c55d_post)
2673    
2674    checkpoint55f_post
2675    o rename to timeave_init_fixed
2676    
2677    checkpoint55e_post
2678    o some delicate re-shuffle of store directives to avoid one
2679      extra call of do_oceanic_physics
2680      affects ecco_the_main_loop.F, do_oceanic_physics.F
2681      checkpoint_lev1_directives.h
2682    o NB: this may break global_ocean adjoint temporarily,
2683      but it is clear how to fix it. Will do later, need this now.
2684    
2685    checkpoint55d_post
2686    o ECCO specific cost function terms (up-to-date with 1x1 runs)
2687    o ecco_cost_weights is modified to 1x1 runs
2688    o modifs to allow observations to be read in as
2689      single file or yearly files
2690    o enable to read exf forcing fields as either
2691      single file or yearly files (flag useExfYearlyFields)
2692    checkpoint55d_pre
2693    
2694    o switch between 2-level and 3-level checkpointing
2695    o add ability of MNC to write local and "partial" (eg. 2D slices where
2696      the full 3D field is never actually stored) arrays to NetCDF files
2697      with the correct (that is, the complete multi-dimensional) set of
2698      array indicies
2699      - used in mom_vecinv() to write the diagFreq output
2700      - tested (demonstrated) in verification/aim.5l_cs
2701    o further mnc-ification
2702      - add verification/lab_sea to the list with mnc setups
2703      - fix undefined mnc v-names in cd_code
2704      - add kpp to mnc output (both snapshot and timeave)
2705    o non-hydrostatic code
2706      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
2707        in calc_gw.F
2708      - defaults to viscAh
2709      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
2710        friction or Leith) in non-hydrostatic mode, as long as there is
2711        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
2712    o pkg/cost
2713      extend simple cost functions to treat time mean quantities
2714      (T,U,V) via cost_accumulate_state from cost_tile
2715  o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to  o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
2716      be 2 times larger than the minimum size the advection scheme requires.      be 2 times larger than the minimum size the advection scheme requires.
