4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice
8     - fix diagnostics of principal stress components for EVP
9     - add optional diagnostics of non-linear convergence for LSOR solver
10    o model/src (3-d solver):
11      Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49),
12       which consisted in removing the Surf. Non-Hydrostatic pressure from the
13       whole column and adding it to Eta (inspired from Casualli, 1999):
14       Only affects 3-D solver initial guess and only if using ExactConserv,
15       but tests did show a degradation of solver convergence. For this reason,
16       decide to disable this piece of code.
17       to recover previous version, just set zeroPsNH = exactConserv (line 78).
18      Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW
19    o pkg/ggl90:
20     - fix previous modif (unfortunatly has not been documented here).
21    o pkg/seaice/autodiff:
22     - add CPP flag to include clipping of zeta in EVP code;
23       although clipping of zeta is not necessary for EVP and not recommended
24       it was done by default, now clipping is disabled by default
25     - modify computation and store zetaC/Z in seaice_evp for TAF
26     - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)
27     - change seaice_calc_viscosities/strainrates for better
28       vectorization after AD by TAF
29     - rearrange common blocks in SEAICE.h once again for easier dumps of
30       adjoint output, adjust adcommon.h and g_common.h
31     - change flux form of default advection scheme for better vectorization
32       of adjoint code
33     - modify lab_sea/input.lsr to test the flux form of default advection
34       scheme
35    o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level
36      transition in checkpoint61r)
37    
38    checkpoint61x
39    o adjoint: adding two new verification experiments
40      * tutorial_global_biogeo: an online dic sensitivity experiment
41        (work with G. Forget)
42      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
43        (an update of the Dutkiewicz et al., 2006 paper)
44      Both use the same CO2FLUX cost function, but different controls
45      Gradient checks look good, but some recomp. could still be traightened out
46      Should add xx_dic control variable to test at some point
47    o model/src:
48      add run-time parameters to check and/or mask initial Temp & Salt
49    o pkg/ptracers:
50      apply zonal filter (if used) to all passive tracers
51    
52    checkpoint61w
53    o adjoint:
54      * update and finish work on adjoint of dic package (G. Forget)
55      * start adjoint of offline package
56      * bug fix for cube-sphere TLM code (active_file_g.F)
57    o tutorial_global_oce_optim:
58      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
59      and add SIZE.h_mpi for MPI testing
60    o pkg autodiff
61     - fix bug in autodiff_restore
62     - make genmake2 remove comments and empty lines from ad_input_code.f in
63       order to reduce file size (new script file remove_comments_sed)
64    o allows to specify vertical profile of vertical viscosity (viscArNr)
65    o pkg autodiff
66      autodiff_ini_model_io: comment out writing of grid information to netcdf
67      files, because at this time the grid fields are a bunch of zeros
68      (this is analogous to ini_mnc_vars.F)
69    o pkg seaice/autodiff:
70     left-over from removing the 3-time-level fields:
71     - small rearrangement of common blocks (SEAICE.h)
72     - fix field declaration in order to get meaningful output in
73       adseaice.*.nc (adcommon.h)
74    o pkg obcs:
75     - go through NH code only if nonHydrostatic=T
76     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
77     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
78       => Update output of experiment seaice_obcs
79     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
80     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
81     - fix restart for useOBCSprescribe + useEXF
82    o pkg ctrl
83     - make obcs as control parameter work also with useSingleCPUio
84     - replace a few sny and snx by Ny and Nx to be consistent with
85       ctrl_set_globfld_x/yz.F
86    o pkg seaice
87     - re-introduce global field frWtrAtm for the case of
88       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
89     - catch the case of an empty filename in seaice_cost_init_fixed.F
90    o pkg ecco:
91     - small bug fixes in the_main_loop
92      . fix order of monitor arguments
93      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
94      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
95        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
96     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
97       imbalance diagnostics for wmean_h/sflux = 0
98     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
99     - catch the case of empty filenames in ecco_cost_init_fixed.F
100       and ecco_readparms.F
101     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
102       to make this statement meaningfull in ecco_cost_weights.F
103    o pkg zonal_filt:
104      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
105      - when using rStar, filter uVel*hFacW instead of uVel
106       (tested without topography: fix a Pb of growing instability with NLFS)
107    o pkg/aim/thsice:
108     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
109      (works as SST restoring)
110    o pkg/thsice:
111     -add specific parameter for salt restoring in slab mixed-layer
112       (by default equal to the temperature restoring)
113    
114    checkpoint61v
115    o pkg/kpp:
116     -add double diffusive contributions as a hack, turned off by default
117      for now, and the code can be excluded with a CPP-flag
118      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
119     -add a verification experiments to "vermix" to test this code
120    o pkg/mom_common:
121      Move computation of length scales to mom_init_fixed.F (avoid recomputation
122      at each time-steps*levels).
123    o pkg/layers:
124      Created a new package for computing volume fluxes in temperature or
125      [not yet implemented] density layers, e.g. for calculating residual
126      overturning circulations.
127    o pkg/diagnostics:
128      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
129    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
130    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
131      To avoid mixing type (RS/RL) of input/output array argument,
132      replace single mixed-type array with a pair from each type (RS/RL).
133    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
134      is now implemented for all pkgs (previously only done for the main pickup)
135    
136    checkpoint61u
137    o pkg/obcs:
138      - change OB?eta from _RS to _RL and put them into a separate commen block
139      - add code to read OB?eta from a file via obcs_prescribe_read: the code
140        compiles and does not destroy any other experiments, the data is read
141        properly, but the code is not tested in actual applications
142    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
143      create a meaningful unit attribute for the time coordinate variable
144    o pkg/ebm: add plenty of missing "_d 0" ;
145       update results of experiment global_ocean_ebm (fwd + adjoint tests)
146      Notes: several pieces of code only works for (very) specific set up
147       (domain size, lat range, etc ...); should be documented & stop if one
148       of those assumptions is not meet.
149    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
150       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
151          and offline_exf_seaice (seaicetd + adjoint).
152    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
153       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
154        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
155    o few changes to pass when compiling with strick checking of arguments
156       across S/R (allow to find few bugs in S/R calls).
157    o pkg/seaice:
158     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
159       2d-fields, for slightly better performance
160    
161    checkpoint61t
162    o pkg/seaice:
163     - remove unused variables in seaice_evp
164     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
165    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
166       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
167       each processor opens a different file (a fix from Matt).
168    o cg2d:
169       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
170       this reduces number of EXCH calls by 2 when using exch2.
171       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
172       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
173    o pkg/thsice:
174       add code for Near Infra-Red albedo (from Jeff)
175       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
176    o ini_model_io:
177       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
178       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
179       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
180    
181    checkpoint61s
182    o pkg/exch2 (exch2_rxN_cube*):
183       remove last BARRIER (no need to synchronise after getting data from shared
184       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
185    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
186      and generate new output (for the 2 tests) using default rotationPeriod.
187    o pkg/exch2:
188      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
189        (was already the case with AUTODIFF_EXCH2 defined)
190      - add bj in exch2 arrays and S/R.
191      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
192        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
193    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
194      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
195        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
196      - verification experiment natl_box.longstep
197    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
198      allow different versions of ifort (8 or 9) and different versions
199       of mpi (mpich or mpich2) to be used with the same optfile.
200      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
201       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
202    o pkg/seaice:
203      fix previous modif (3-level field removed) for old-pickup reading
204    
205    checkpoint61r
206    o pkg/seaice:
207     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
208      1. introduce fields for time step (N-1)
209      2. do not use levels 2 and 3 anymore (but keep them)
210      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
211         includes changes to pkg/thsice/thsice_get_velocity.F,
212         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
213         pkg/obcs/obcs_apply_uvice.F.
214     - completely remove code for leap-frog time stepping for second order
215       advection
216     - adjusted adjoint accordingly;
217       gradient checks have improved by an order of magnitude!
218    
219    checkpoint61q
220    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
221     - the boundary conditions along open boundaries are unclear, because the
222       associated masks are set to zero and are thus treated as closed when
223       applying the slip-boundary conditions.
224     - move initialisation of grid variables from seaice_init_varia to _fixed
225    o adding doc/diags_changes.txt
226    o model/src:
227      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
228       to avoid "_diags" naming if no relation to pkg/diagnostics.
229      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
230       file and only call PLOT_FIELD_XYZ if debugMode=T.
231      remove few PLOT_FIELD_XY calls outside initialisation.
232      remove few unnecessary BARRIER.
233    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
234      of salt_plume package in Southern Ocean
235    o pkg/thsice:
236     - fix hOceMxL in overlap (needed for sea-ice advection);
237       update output of experiment global_ocean.cs32x15.icedyn.
238    o pkg/seaice:
239     - make the (placeholder-)tracer IceAge a little more meaningful
240      by avoiding ridging of age due to convergent ice flow
241     - add diagnostics for surface temperature, atmospheric and oceanic
242       heat flux, and atmospheric and oceanic ice growth
243    
244    checkpoint61p
245    o eesupp (global_max & global_sum):
246     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
247     - remove starting & endding barrier (no longer needed)
248    o pkg/mdsio, writelocal:
249       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
250       (remove the STOP): uses shared buffer IO to store data from all threads
251       and then let master-thread write nThreads tiles.
252    o pkg/mdsio (read/write field):
253     - tiled IO done in 1 piece (all levels at a time);
254     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
255     - multi-threaded: allow to read/write local (non-shared) array
256       (was already working with singleCpuIO ; now works also without);
257       => no longer needs barrier call after reading a file (added inside
258       mds_read/write field).
259     - move barrier calls outside gather/scatter_2d to mds_read/write_field
260    o pkg/obcs/exf
261      - exf_getffieldrec.F: add a few ". _d 0" and
262                            add code to catch the case fldperiod = 0.  
263      - obcs_precribe_read.F: change if statements so that they match
264                              the variable type (_RL)
265      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
266        exf_iprec) as part of namelist EXF_NML_01
267    o pkg/mdsio:
268      - read/write tiled (local) files: read/write 1-level tile chunk at a time
269        (instead of segment of length sNx); expected to speed up tiled IO.
270    o pkg/exch2:
271      - take buffer copy from/to array out of S/R exch2_send/recv into new
272        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
273        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
274      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
275      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
276        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
277        including Topology header file (and common blocks).
278      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
279        remove 2nd exch call in exch2_s3d_rx (no longer needed).
280      - document S/R arg. list (+ update some comments)
281    o pkg/seaice:
282      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
283        temperature and humidity over sea ice based on climatological values.
284      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
285        of LSR (this change is expected to change the results slightly because now
286        it uses slightly difference moduli from the second last LSR solution, but
287        that is more consistent with the stress computations; this part of the code
288        is not tested in the verification experiments)
289      - fix diagnostics for flux of ice in case of B-grid
290      - turn strain rates eij and press into global fields within global
291        common block in SEAICE.h for more straighforward diagnostics
292      - fix diagnostics for principal stress components, press, zeta, eta
293        to give something meaning full
294    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
295      new output (all 4 tests) using default rotationPeriod.
296    o pkg KPP:
297      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
298      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
299        and normal grid from 1 to Nr)
300    o Fix computations of L4rdt in mom_calc_visc.F
301    o eesupp:
302      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
303      should be called before a "stop" if we know that all process are going
304      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
305    
306    checkpoint61o
307    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
308    o model/src/ini_curvilinear_grid.F:
309       compute angleSin/CosC when they are not read from a file
310    o pkg/seaice:
311       add pseudo time stepping for LSOR
312    o pkg/exch2:
313       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
314    o pkg/seaice:
315       Adding separate sea ice albedo, drag coefficients, and HO in Southern
316       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
317    o SingleCpuIO:
318       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
319    o pkg/seaice:
320       put exchanged variable in (local) common block for MPI+Multi-Threads
321       to work (necessary with exch1, and for now with exch2 too).
322    o verification: to get more experiments tested with mpi, mth and mpi+mth,
323      change tiling of:
324       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
325       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
326      update output of exp:
327       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
328       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
329      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
330                       (note: output.txt generated on faulks using only 1 tile)
331    o eesupp & mdsio (SingleCpuIO):
332     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
333       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
334       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
335     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
336     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
337       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
338    o pkg/exch2:
339     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
340       read parameter file "data.exch2" if it exists; otherwise try default regular
341       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
342     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
343       with new code (not to be used, just as a backup solution).
344     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
345       in utils/exch2/input.
346    
347    checkpoint61n
348    o eesupp & mdsio (SingleCpuIO):
349      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
350        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
351        receive real*4 array (instead of real*8) to read/write 32.bit files.
352        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
353         and remove new mapping S/R)
354    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
355      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
356        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
357        when using exch2. Add S/R to map global io-buffer to global model array.
358      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
359    
360    checkpoint61m
361    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
362      and add 3 other S/R for other types (R4,R8,RS).
363      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
364    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
365     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
366     - reduce number of macro definitions (keep only those which are used);
367       can always call directly the corrresponding S/R if needed.
368     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
369       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
370     Fixed wrong type of arg in:
371       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
372       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
373     To fix: global_sum of var in common block is wrong (multi-threaded) in:
374       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
375     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
376    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
377      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
378    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
379    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
380      edges are closed (zero depth); might happen with "blank tiles";
381      for now, disabled if using OBCS.
382    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
383      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
384    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
385      to reduce length of 1.D array print in STDOUT.
386    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
387      + use 48 tiles (16x8): this will allow to test "blank tiles".
388    o start to test MPI + multi-threaded (change testreport to skip tests
389      where number of tiles do not match).
390    o genmake2: add option "-omp" to turn on Open-MP ;
391      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
392    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
393      and keep the original tile numbering. Note: compatible with old
394      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
395    
396    checkpoint61l
397    o Overlaps had been forgotten in calculating ijk keys : fixed
398    o fix cyrus makedepend for gcc 4.4
399    o experiment fizhi-cs-aqualev20:
400      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
401      and generate new output. Note: new output is much closer to the old
402      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
403      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
404    o pkg/fizhi:
405     - change to avoid indices going deliberately over array-bounds
406     - remove unnecessary MPI stuff
407     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
408     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
409       does not go over array-bounds and therefore returns reliable output.
410     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
411       this S/R has 4 output arguments, which are used inside "get_alarm";
412       when it is called with the same variable "ndum" in place of several
413       output arguments, this produces weird side effect inside "get_alarm"
414      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
415       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
416       address) and produces error.
417    o tools/gemake2: (March 27-29 2009)
418      with option "-mpi": link *_mpi files from "MODS" dir (this is what
419      testreport does).
420    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
421    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
422       update lab_sea.lsr & lab_sea.salt_plume results
423    o pkg/seaice:
424      Major overhaul of the LSOR solver: change discretization from original
425      finite differences to finite volume. The old routine is still in the
426      file seaice_lsr.F and can be turned on with the CPP-flag
427      SEAICE_OLD_AND_BAD_DISCRETIZATION
428      Along with this change, the discretization of the strain rates is changed.
429      The same flag turns on the old discretization in seaice_calc_strainrates.F
430      All verification experiments with seaice are affected (except for
431      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
432      results by setting the above flag.
433      Further changes involve changes in defaults:
434      - ALLOW_FLOODING is defined and turned on by default
435      - SEAICEadvSnow = .true. is now the default
436      - SEAICEadvSalt = .true. is now the default
437      - SEAICEadvAge  = .true. is now the default
438      - SEAICE_clipVelocities  = .false. is now the default
439                                         (as per J. Zhang's recommendation)
440      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
441        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
442      - seaice_growth: replace computation of UG by a simple copy from wspeed
443    
444    checkpoint61k
445    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
446      seaice_lsr: fixed a few metric terms,
447                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
448                  add more debugging diagnostics
449      seaice_evp: removed superfluous many metric terms of FV discretization
450                  of stress divergence
451                  affects lab_sea, lab_sea.hb87
452      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
453                  of stress divergence for non-evp solver
454                  (this part is not tested anywhere)
455      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
456                  they were effectively only half slip
457                  affects lab_sea.hb87
458      updated all relevant verification experiments (except lab_sea//output_adm.txt
459        which was left over, but fails at level 7 & 6)
460    
461    checkpoint61j
462    o pkg/seaice: turn a few hard wired parameters into run time parameters
463    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
464      time in seconds as promised by the usints in seaice_monitor and exf_monitor
465    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
466      that are not cubed-sphere grids
467    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
468    o pkg/ctrl:
469      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
470    o non-hydrostatic (calc_gw.F):
471      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
472      update output of exp. global_ocean.cs32x15.viscA4
473    o remove backward compatibility for thetaMin,phiMin
474      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
475    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
476      interpolated wind field not only for curvilineargrid=.true., but also
477      for a rotated grid (rotateGrid=.true.)
478    o pkg/exf: add capability to bypass interpolation for runoff
479      by setting yet another CPP-flag
480    o eesupp/src, B-grid exchange:
481      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
482    o autodiff
483      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
484      allows to switch to single-prec common blocks;
485      corresponding switch occurs in tamc.h, integer isbyte
486      TAF store directivs "byte" and "kind" seem equivalent;
487      Most tamc.h have been updated correspondingly.
488    
489    checkpoint61i
490    o autodiff:
491      fix autodiff_sore/_restore indices for obcs
492      (spotted by I. Hoteit, M. Mazloff)
493    o pkg/autodiff, pkg/ctrl:
494      Add flag to reduce all tapelev I/O to single-prec.
495      In data.ctrl set
496        doSinglePrecTapelev = .TRUE.
497    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
498      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
499    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
500      real fresh water flux (not yet)
501    o pkg/mdsio & rw:
502     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
503     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
504    o pkg/flt:
505     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
506       init_fixed & ini_varia.
507     - clean-up & simplify linear interpolation S/R:
508       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
509     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
510     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
511     - add vert. coordinate & horiz. indices to output files.
512     - change vertical position in initial condition, from index to depth [m].
513     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
514       (easier to get to a curvilinear grid) ; delX,delY no longer used.
515    o pkg/ggl90: a few modifications:
516     - fix bottom boundary condition, and interpolation of KappaE
517       near top and bottom
518     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
519     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
520     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
521    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
522      (maintain temporary backward compatibility, until next checkpoint)
523    
524    checkpoint61h
525    o pkg/diagnostics with "periodic averaging diagnostics":
526      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
527    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
528    o pkg/obcs: fix loop ranges for balancing code
529    o pkg/flt:
530     - improve criteria for finding which tile owns a float.
531     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
532    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
533      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
534      with ocean biogeo)
535    o pkg/flt:
536     - do some cleaning and fix the restart ;
537     - add output.txt in flt_example/results to get this pkg tested.
538    o genmake2: add an EXTENDED_SRC option and flag.
539       for now, cannot be turned on on command line (only through genmake_local)
540    o pkg/mdsio: read/write vector:
541     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
542     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
543       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
544     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
545      (drop to 4 digits matching for grad). But this test does not look very
546      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
547    
548    checkpoint61g
549    o pkg/flt:
550      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
551       + make OPTIONS file more standard.
552      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
553      - fix _BYTESWAPIO CPP-Flag
554      - standard reading of file-parameter "data.flt"
555      - fix argument list of S/R FLT_RESTART
556      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
557    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
558    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
559      a still unfixed compiler/optimization bug
560    
561    checkpoint61f
562    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
563      update results of global_ocean.cs32x15.icedyn test.
564    o move getcon.F from model/src to pkg/fizhi.
565    o pkg/exf: add parameter for extrapolation of temp up to the surface
566       and option to prevent negative evap (in bulk_largeyeager04 only).
567    o Prather Advection scheme: fix tracer conservation for divergent flow
568      (e.g., when using NonLin Free-Surface).
569    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
570    o gmredi (Visbeck-variable-K):
571     - add more parameters to Visbeck-variable-K.
572     - use a 5 points average for dSigmaR in Visbeck-K calculation
573       (more "homogenous": same stencil and same weights as in dSigmaH)
574     - update output of ideal_2D_oce experiment.
575    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
576      (#undef REAL4_IS_SLOW)
577     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
578       coordinate variable
579     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
580       (surface forcing fields), removes some of the functionality
581     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
582     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
583       probably not all: copy _RS surface flux fields to RL field before
584       calling DIAGNOSTICS_FILL
585     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
586       real*4 (CALL EXCH_*_RS) versions.
587     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
588       (generate new output).
589    
590    checkpoint61e
591    o gmredi (Visbeck-variable-K):
592      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
593      - change computation of Visbeck-K where Slope > Smax :        
594        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
595        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
596    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
597      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
598    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
599    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
600      does not become too large (to avoid precision problems in implicit-diffusion
601      solver); update ideal_2D_oce output.
602    o pkg ggl90:
603      - in ggl90_cal.F: compute only one set of visc/diff, used to
604        step forward TKE/T/S/momentum
605      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
606        have Prandlt =1)
607    o gmredi (fm07):
608      - add lower limit on Transition layer thickness + lower limit on 1/lambda
609      - allow to set few more params from data.gmredi
610    o pkg ggl90:
611          - add missing sqrt(2) factor in computation of mixing length
612            scale in ggl90_calc.F
613            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
614    
615    checkpoint61d
616    o adjoint modifs
617      - adapt to new field rhoInSitu
618      - allow to revert from StoreDynVars2D, StoreDynVars3D
619        to individual fields
620        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
621    o store 3-D (in-situ) density in commom block (DYNVARS.h)
622     - save 1 rho computation.
623     - no longer modify T & S inland when using down_slope pkg.
624    o gad_som : allow to switch to SOM advection for T & S without corresponding
625      pickup files (using new S/R: MDS_CHECK4FILE).
626    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
627      (for useSingleCpuIO to work in multi-threaded)
628    o pkg/shelfice:
629     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
630       with SHELFICEtopoFile in data.shelfice
631     - move code for reading ice shelf topography and modifying hFacC into separate
632       subroutines of the shelfice package
633     - separate initialisation of "fixed" and "variable" variables
634     - kTopC is not (yet) replaced by kSurfC, although this is possible
635    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
636    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
637      and rename:
638      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
639      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
640    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
641    
642    checkpoint61c
643    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
644      to add mass source/sink of fluid in the interior (3-D generalisation
645      of oceanic real-fresh water flux).
646    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
647    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
648    o new pkg: down_slope
649      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
650      - presently, modify T & S inland (dwnslp_calc_rho.F).
651        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
652      - implementation for ocean in P-coords not tested.
653      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
654    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
655      (to facilitate conversion of oceanic pkg to p-coordinate).
656    o change FIND_RHO to FIND_RHO_2D :
657      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
658    o new pkg: cheapaml
659    
660    checkpoint61b
661    o exch2:
662      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
663      - no longer depend on the order sequence (N,S,E,W).
664      - 3rd exchange no longer needed (tested with 24 tiles).
665      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
666      - exch_UV_A-grid readily available (but not yet tested).
667      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
668      (both are no longer needed) in exch_uv: no effect in forward run; but
669       get truncation error differences with adjoint exch.
670    o exch2:
671     - change index-bounds storage (moved from target to local tile,
672       more intuitive this way) ; rename/remove some variables.
673     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
674    
675    checkpoint61a
676    o exch2/matlab-topology-generator:
677      fix bug in index bounds for N-S internal exchange (hard to tell if this
678      had any effect on the solution).
679    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
680      is exceeded
681    o testreport: modify syntax of awk, so that it works also with
682      awk, and not only with nawk and gawk
683    
684    checkpoint61
685    o autodiff
686      Change default for TAF usage by removing argument '-nonew_arg'
687      This changes TAF subroutine argument list (ordering of active var.)
688      Omission of this flag leads to incompatibility w.r.t. TAMC
689      To restore TAMC-compatibility, need following modifs:
690      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
691      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
692      Tested TAF version is 1.9.22
693      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
694    
695    checkpoint60
696    --->>> This is the last checkpoint for which generating the adjoint
697    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
698    --->>> by default.
699    --->>> Future checkpoints will ommit this flag by default.
700    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
701    o pkg/grdchk: Add gradient check to etan0 perturbations.
702    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
703    o pkg/autodiff: more flexibility in zeroadj.
704      model/src: modifying do_oceanic_phys.F accordingly.
705    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
706    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
707      special setup of gmredi for which the adjoint is stable
708      enough for parameter optimization.
709    o bridging the gap between eddy stress and GM.
710      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
711          along with a change in CPP option (now ALLOW_EDDYPSI).
712      -> when using GM w/ GM_AdvForm:
713          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
714          is applied either in the tracer Eq. or in momentum Eq.
715          depending on data.gmredi (intro. GM_InMomAsStress).
716      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
717      The key modifications are in model/src/taueddy_external_forcing.F
718      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
719    
720    checkpoint59r
721    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
722      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
723      fix option to read coriolis(@ cell-corner) from files with CS-grid.
724    o pkg/mnc: add some attributes to standard 1D-coordinate variables
725    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
726      mass points, when using mnc for output
727      - add runtime parameter (missing_value, missing_value_int) to override
728        default (which is the value of getcon('UNDEF'))
729    o pkg/mnc: prepare mnc for the actual use of missing values with the
730      diagnostics package: small fix in mnc_cw_readwrite.template and more
731      initialisation of never used fields
732      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
733      versions
734    o pkg/thsice/thsice_ini_vars.F added default initial values so that
735      thermodynamics sea ice solver does not blow up when some initial fields
736      are missing.
737    o move from external_forcing_surf.F to ini_forcing.F
738      the p-coord. hack consisting in using pLoad to set phi0surf ;
739      update output of tutorial_global_oce_in_p (affected @ truncation level).
740    o Freshen up a bit hs94.1x64x5, notably:
741      remove rotationPeriod and tRef=5*0. (adjoint only), and add
742      exactConserv=.TRUE.
743    o pkg/generic_advdiff:
744      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
745      applies to files where Temperature & Salinity 2nd Order moments are used.
746    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
747      this uses a dynamically allocated internal state data structure
748      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
749      and requires a fortran 90 compiler
750    
751    checkpoint59q
752    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
753       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
754    o Refresh tutorial_global_oce_biogeo, notably:
755      - change bathymetry (put back seamounts in ACC, use hFacs)
756      - change EOS (POLY3 --> JMD95Z)
757      - use Bryan-Lewis vertical diffusivity
758      - use multidimensional advection
759      - remove old virtual virtual in dic pkg, now done through ptracer pkg
760      - change a couple of parameters in dic pkg
761    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
762    o pkg/obcs: change default to OBCSfixTopo = .true.,
763      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
764      - replace "debugMode" with "debugLevel .GE. debLevB"
765    o implementation of TAF directives for gchem,cfc,dic
766    o remove "exp5" (replaced by tutorial_deep_convection).
767    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
768      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
769      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
770      --> changes results in exp4, seaice_obcs
771    o tutorial_deep_convection :
772      update the set-up and increase resolution and domain size ; start
773      from pseudo initial conditions = output at t=120mn in order to see
774      something happening when running testreport.
775    o pkg/seaice: add os7mp as an advection scheme
776                  add check for advection schemes
777                  add a flag for restoring T and S underneath sea ice
778    o pkg/my82: add netcdf-support and diagnostics
779    o thsice pkg:
780      - Now hsMax limits snow height by turning it into ice following
781        flooding scheme (and now conserving energy)
782      - Slight rewriting of the formula in thsice_calc_thick.F
783      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
784      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
785    
786    checkpoint59p
787    o gchem / dic / cfc :
788      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
789      - add new parameter files: "data.dic" & "data.cfc" ;
790      - various re-arrangement in initialisation & header file ;
791      - fix tutorial_global_oce_biogeo for multi-threaded test.
792    o pkg/dic: test for "pickup_dic" file when restarting ;
793      if no pickup-file, can restart with a re-initialised pH (same as it did
794      before) providing pickupStrictlyMatch is set to False.
795    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
796      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
797    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
798      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
799    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
800     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
801       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
802    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
803       scheme to use for vorticty-term ;
804     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
805       (with default selectVortScheme, return to original discretisation)
806     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
807    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
808    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
809      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
810      also fix diagnostics VISCAHW & VISCA4W.
811    
812    checkpoint59o
813    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
814    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
815      move a few statemens out the main loop into separate loops
816    o pkg/shelfice:
817      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
818        (kg/m^2/s), does not break tests, because in verification/isomip,
819        rhoConstFresh=rhoConst (by accident)
820      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
821      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
822        new file model/src/seawater.F, so that they are available for all pkgs.
823      - convert potential temperature into in-situ temperature. This changes the
824        isomip tests => update tests
825    o add a flag writePickupAtEnd (default=true) to be able to suppress
826      writing a pickup at the last timestep
827    o tools/mpack-1.6 :
828      - disable automake (not working) and autoconf (not needed).
829      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
830        also cleaner with much less compilation warnings.
831    o pkg/profiles:
832      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
833      (for "less than 32 characters name" compiler requirement)
834    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
835      conditions that have a different sampling frequency than S/T/U/V obcs
836    o pkg/diagnostics (stats-diags):
837      - fix global Min/Max in case 1 processor get only empty tiles
838    o genmake2: replace (4 times)
839         make genmake_tc_1.o >> genmake_warnings 2>&1
840      with
841         COMM="$CC $CFLAGS -c genmake_tc_1.c"
842         echo $COMM >> genmake_warnings
843         $COMM >> genmake_warnings 2>&1
844      to make genmake2 always see the value of CC as specified in the optfile.
845    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
846      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
847      - modify verification advect_cs test to test SOM-advection on CS-grid.
848    o pkg/ctrl:
849      - Rewrite of ctrl_map_ini_ecco.F,
850        introducing a generic routine (ctrl_map_ini_gen.F).
851      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
852    
853    checkpoint59n
854    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
855      number in dedicate array "hdiag":
856      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
857        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
858      - many small changes (integer format) for large number of diagnostics
859      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
860        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
861    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
862      usingSphericalGrid, this allows to define the rotated grid coordinates
863      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
864      geographical coordinates according to the inverse of the rotation defined
865      by the Euler angles, so that Coriolis parameter and online-interpolation by
866      exf works with the geographical coordinates on XC/YC/XG/YG.
867      Naturally, this feature does not work with all packages, so some
868      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
869      profiles), because there the coordinates are assumed to be regular
870      spherical grid coordinates.
871    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
872      - introduce isopycnal diffusion coefficient control.
873    o tools/adjoint_options:
874      - additional control vector components.
875    o pkg/mnc: have mnc create marginally meaning full coordinate variables
876      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
877    o pkg/mypackage:
878      - add example of read/write pickup for state-var ;
879      - add entry points to the main code for state-vars diags & write-pickup.
880    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
881      transitions for useExfYearlyFields
882      - add new subroutine that determines the file to read from for
883        use*YearlyFields = .TRUE. and .FALSE.
884      - add a verification experiment to global_with_exf that tests
885        useExfYearlyFields with USE_EXF_INTERPOLATION defined
886    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
887      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
888      subroutines (which could be generated from a template, because they are
889      almost identical), for now they are included in obcs_prescribe_read.F for
890      simplicity
891    o pkg/exf:
892      - add a little more diagnostic to exf_interp_read (in analogy to
893        mds_read_field, can be turned off with debugLevel < debugLevA=1)
894      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
895        ugly but fast by unrolling short inner loops, inserting a unroll=8
896        directive in routine lagran, and splitting a loop and making do while the
897        outermost loop (the latter requires the intoduction of index arrays)
898    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
899    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
900      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
901    o verification/seaice_obcs: updated for restart test and latest options
902    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
903      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
904      for now this is only available for the C-grid code and also within
905      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
906    
907    checkpoint59m
908    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
909      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
910    o gad_som : fix flux output (& diagnostics) to have same units as other  
911      advection scheme fluxes (was previously multiplied by deltaT).  
912    o added verification/seaice_obcs both to test seaice open boundaries
913      and to provide an example matlab scrpt for generating them
914    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
915    o pkg/salt_plume: clean up salt_plume_frac.F to
916      remove redundancy in PlumeMethod 1 and 4
917    o pkg/kpp: added saltplume diagnostics
918    o pkg/obcs and pkg/seaice:
919      - do not set uice and vice to zero when OB*icefile are unspecified
920      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
921      - moved seaice tracer obcs after call to seaice_growth
922    o pkg/salt_plume: added various options for salt plume depth
923      criterion and for vertical distribution of the salt
924    
925    checkpoint59l
926    o pkg/ptracers: new version of ptracers pickup:
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:
930      - add timescale for melting due to warm mixed layer as a means of
931        setting SEAICE_availHeatFrac more conveniently
932      - add a CPP-flag/runtime parameter check for flooding algorithm
933      - reformulated availHeat in seaice_growth.F to be independent of AREA
934    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
935      unit changes
936    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
937    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
938      SX vector computer.
939    o pkg/seaice:
940      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
941        seaice forcing fields can now be read only through pkg/exf
942      - removed some unused halos
943    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
944    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
945      or U/VICE from U/VWIND before computing U/VSTRESS
946    
947    checkpoint59k
948    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
949      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
950    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
951      all experiments pass when compile with un-initialised var. checking option.
952    o added pkg/salt_plume
953    o script to test restart (for now, in MITgcm_contrib/jmc_script)
954    o pkg/seaice: new read/write pickup version.
955      read meta file and write only fields which are needed to restart.
956      ( same logic as main pickup file ; also using pickupStrictlyMatch )
957    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
958    o lab_sea.hb87: modify the domain & update output.hb87.txt :
959      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
960      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
961      process. Fixed here by closing the domain at the Northern boundary.
962    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
963    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
964      a set of consecutive levels in/from a 3-D array.
965    o pkg/ptracers:
966      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
967      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
968    
969    checkpoint59j
970    o in pkgs: dic, obcs, offline, rbcs:
971      standard way to compute coeff. for time interpolation between 2 time reccords
972      which retains full precision (& make results less dependent on compiler).
973      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
974    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
975      packages instead of reading ice cover and wind speed separately
976    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
977     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
978      to allow to compile customized code before the update)
979    o cleaning-up:
980      - fix CPP instruction syntax in pkg/obcs
981      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
982        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
983      - fix some threads issue in IO parts.
984    o pkg/dic:
985      - add tons of "_d 0" (--> much better testreports !)
986       and then update outputs of tutorial_global_oce_biogeo
987    o pkg/mom_fluxform:
988      add a special version of momentum advection intended to conserve momentum
989      next to a bathymetry step or a coastline edge. (default = off = #undef)
990    o new read/write pickup version:
991      - for now, only implemented for main (mdsio) pickup file.
992      - write out only what is needed to restart; merge pickup_nh , pickup_ph
993        and main pickup together.
994      - read meta file; read only what is needed to restart; stop if a field
995        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
996        if it make sense (even if the restart is not perfect).
997      - if no meta file, assume that pickup to read corresponds exactly to
998        a pickup that would currently be written.
999      - read pickup written in the old format (until checkpoint59i) if it
1000        recognizes an old meta file (no field-list).
1001      - add a meta file in exp. which starts from a pickup: 2 cases:
1002        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
1003         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
1004        b) a meta file describing the content of the associated pickup file
1005         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
1006    o pkg/mdsio & pkg/rw:
1007      - new routine to read a meta file ; new set of routine to read
1008        Multiple-fields file (with meta file).
1009    o added open boundary conditions capability for seaice
1010        HSNOW, HSALT, UICE, and VICE
1011    
1012    checkpoint59i
1013    o adjoint:
1014      * fix multiDimAdvection adjoint
1015        (partial recomputation problem by TAF for fVerT(:,:,kDown)
1016        and comlev1 size definition (maxpass vs. max. number of tracers)
1017      * verification/global_ocean.90x45x15 adjoint now tests
1018        NLFS and multiDimAdvection using DST3 (=30)
1019      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
1020    o pkg/kpp: add "_d 0" to real constant (if missing);
1021      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
1022      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
1023    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
1024      for internal parameters related to restart process (formerly from PARAMS.h)
1025      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
1026    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
1027      as argument. (only atm2d & obcs write_pickup have not yet been updated)
1028    o pkg/monitor:
1029      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
1030      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
1031      - account for deep Atmosphere factor and density factor (anelastic)
1032    o added open boundary conditions capability for seaice HEFF and AREA
1033    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
1034      thermodynamics
1035      - requires a little reorganization, which affects the testreport results
1036        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
1037        so that now the conservative form is tested
1038      - add a few comments
1039    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
1040    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
1041    o add new diagnostics to seaice: advective, diffusive fluxes (only for
1042      multidim-advection, for scheme 2 they are not filled) and transports,
1043      thermodynamic growth rates
1044    o change units of EmPmR (inside the code, + within coupling interface)
1045      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
1046      Affects results @ truncation level (cg2d match) and update output of
1047       experiments: lab_sea(6), global_ocean.90x40x15(10),
1048      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
1049      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
1050      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
1051      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
1052    
1053    checkpoint59h
1054    o pkg/exf:
1055      - improve vectorization by moving if-statement out of loops in
1056        exf_mapfields, exf_radiation
1057      - exf_bulkformulae.F: introduce 2D fields and vectorize code
1058    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
1059    o testreport:
1060      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
1061        monitor & update offline_exf_seaice exp. output.
1062      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
1063    o pkg/seaice:
1064      - bug fix in the evp solver: boundary conditions were affected be
1065        masking of zMax/zMin (changes results)
1066      - minor bug fix in boundary conditions in seaice_calc_strainrates
1067        (changes results for no_slip)
1068      - seaice_lsr.F: make interpolation of eta dependent on boundaries
1069      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
1070      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
1071        stress formulation and no-slip boundary conditions
1072    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
1073      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
1074    o pkg/seaice: a first HSALT time stepping equation has been checked in
1075    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
1076      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
1077      without requiring DO-IF statements
1078    o pkg/thsice:
1079      use continuous power-law function for partition of energy between lateral
1080      melting/freezing and thinning/thickening ; old code using step function
1081      still available with #undef THSICE_FRACEN_POWERLAW
1082      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
1083    o testreport: change AD testing : check against results/output_adm.txt
1084      using same scripts as for forward test.
1085    
1086    checkpoint59g
1087    o adjoint testing: in preparation for changing testreport:
1088      - output format: cost and grad written on separated lines
1089      - ad output results in directory "results" (instead of "results_ad")
1090    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
1091    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
1092    o pkg/ecco: allow user defined cost function contributions
1093    o testreport:
1094      Allow to choose (per experiment) the list of tested output variables
1095       and the main variable (used to issue a pass/FAIL ) ;
1096      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
1097      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
1098      Also modify printing of summary:
1099       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
1100       b) echo the list of tested variables in the individual summary.txt of
1101          each experiment.
1102    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
1103      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
1104      (but still depend on the tile decompostion of the domain).
1105    o pkg/seaice: change a discretization detail to make the B-grid code
1106      "more symmetric". This change is likely to remove all "ridges/leads" that
1107      where quasi-aligned with the grid in B-grid solutions. It may also be
1108      the solution to the stress coupling issues with the B-grid.
1109    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
1110      remove .cvsignore from input dir. (since testreport no longer run here).
1111    o pkg/thsice:
1112     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
1113     - fix reshaping of sea-ice just after advection:
1114       melt all the ice only if ice-volume is too small.
1115     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
1116       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
1117     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
1118    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
1119      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
1120    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
1121      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
1122      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
1123      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
1124      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
1125      -> update output.txt
1126    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
1127     this affects truncation error: -> update output.txt of exp:
1128      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
1129      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
1130    
1131    checkpoint59f
1132    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
1133    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
1134      a bounded range (in forward mode)
1135    o pkg/ecco, ctrl, autodiff and mom_common:
1136     internal parameter controls, completements of implementations
1137    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
1138    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
1139      (not seem any difference in testing results).
1140    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
1141       at face corners.
1142    o pkg/generic_advdiff:
1143     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
1144      loop range indices for computing vertical advection tendency
1145      and do the calculation in the interior only (no overlap) ;
1146      for now, only implemented for SOM advection (to save CPU time).
1147     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
1148    o exch2 adjoint
1149      First set of changes:
1150      - add exch2 hand-written adjoint templates
1151      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
1152        This will require cleanup in pkg/autodiff/*.F
1153        (changed routines currently kept separate in verif. code/)
1154      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
1155        that used to hide exch2 or cubed-sphere specific code
1156        (commented via 'cph-exch2')
1157    o pkg/seaice
1158      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
1159    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
1160       output of global_ocean.cs32x15.thsice .
1161    
1162    checkpoint59e
1163    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
1164      for B-grid vector (not yet tested) and C-grid vector (<- only used
1165      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
1166    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
1167      (#ifdef ALLOW_SALT_PLUME)
1168    o gather_2d/scatter_2d: removed halo regions
1169    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
1170      scheme and the corresponding test case (under front_relax dir). For now,
1171      only available with Skew-flux form and not yet tested in realistic set-up.
1172      adjoint: store directives updated, but gradient checks deteriorated,
1173      so maybe GM/Redi adjoint is now broken.
1174    o seaice adjoint
1175      * add AREA, HEFF, HSNOW as control variable
1176        (should not change lab_sea results)
1177      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
1178    o pkg/seaice:
1179      * added computation of saltFlux in seaice_growth;
1180        For time being, sea ice salinity is assumed constant
1181        contribution of snow flooding to freshening of sea ice is neglected.
1182        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
1183        defaults to 0.0 in order to maintain backward compatibility.
1184        Typical values for SEAICE_salinity are 4 to 10 g/kg.
1185      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
1186      * added SEAICE_availHeatFrac, which specifies fraction of surface level
1187        heat content used to melt or grow ice
1188      * commented out cap of HICE: it helps keep ice thinner
1189      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
1190      * applied OBCS T/S mask to HEFFM sea ice mask
1191    
1192    checkpoint59d
1193    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
1194     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
1195     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
1196    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
1197     and change default value of parameter "GM_Small_Number";
1198     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
1199       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
1200       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
1201    o pkg/ecco: cost function when applying pkg/smooth to controls
1202    o pkg/ctrl: add forcingPrecond run time parameter
1203    o pkg/seaice:
1204     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
1205     - fix bug in metric terms of u-equation in LSR solver (implicit part),
1206       changes verification/lab_sea
1207     - rearrange implicit part of u-equation in LSR solver to make it easier to
1208       read, understand, and debug. This causes changes at the truncation level.
1209     - fix (serious) bug in the boundary conditions (sign error in the implicit
1210       part) of the LSR solver. Changes all LSR results.
1211     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1212       is initilized with small values - does not change lab_sea results.
1213     - added HsnowFile initialization capability
1214    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1215     initialization of pkg/smooth and application to control vector
1216    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
1217    o dependencies: pkg/profiles requires pkg/cal
1218    o pkg/profiles:
1219     - added option ALLOW_PROFILES_GENERICGRID
1220         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1221         that interpolation information (grid points and coefficients) is provided
1222         within the netcdf input files.
1223         -> sample matlab scripts can be found in MITgcm_contrib/gael
1224         that allow you to prepare netcdf input files.
1225     - also modified: cleaner include statements, cleaner error print statements,
1226       cleaner stops when error, and more tests of the netcdf input files consistency.
1227    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1228    o pkg/seaice:
1229     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1230       requires a new routine: seaice_diagnostics_fill.F
1231     - make sure that seaice does not move if not forced (pressure replacement
1232       method, Hibler and Ip, 1995), changes results
1233     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1234     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1235       It is turned off by default (=-1.), because it changes the results.
1236     - make it possible to read AREA from a file, too.
1237    
1238    checkpoint59c
1239    o add S/R and diagnostics for oceanic mixed-layer depth
1240    o move GMRedi call after all vertical mixing schemes (including KPP)
1241    o pkg/thsice:
1242     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1243      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1244    o pkg/obcs:
1245     - bug fix for balance code
1246    o pkg/seaice:
1247      - allow values of SEAICE_elasticParm > 1
1248      - add new parameter SEAICE_evpTauRelax as an alternative
1249        to SEAICE_elasticParm
1250      - make lsr boundary conditions free slip (by default), changes result
1251      - add code for no slip boundary conditions for lsr
1252      - set minimum of zeta to zero (and not 4e8) (changes results)
1253      - add a cap on AREA after advecting AREA if seaice_growth is not called
1254    o change calculation of Visbeck K:
1255      - no longer depend on tapering scheme; instead, compute slope (limited
1256        by GM_maxSlope). this is equivalent to what was comuted before with
1257        clipping or linear tappering.
1258      - fix vertical averaging (wrong by 1/2 level)
1259      - leave the old version (but will not be maintained) within
1260        #ifdef OLD_VISBECK_CALC / #endif
1261      - update output of exp. ideal_2D_oce
1262    o change error catch in calc_r_star to improve vectorization
1263    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1264      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1265    o adjoint:
1266      Re-organized adjoint checkpointing according to Matt Mazloff
1267      (but with modifs/completions/cleanups)
1268      Storing is now bundled into large arrays to optimized I/O
1269      (and second step in cleanup of the_main_loop)
1270    
1271    checkpoint59b
1272    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1273      - export/import (between ocean & coupler) fields needed for ocean DIC.
1274    o pkg/seaice:
1275      - get rid of three more exchanges seaice_calc_viscosities (required
1276        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1277      - bug fix in seaice_ocean_stress (update of lab_sea required)
1278      - reduce loop boundaries to necessary minimum also in seaice_evp
1279      - go back to the old way of computing deltaC/Z as the adjoint likes that
1280        better
1281    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1282      passive tracer to an Age Tracer) + update output.txt
1283    o pkg/exf:
1284      - implement A-grid / C-grid selection for wind-stress input files.
1285      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1286      for now, in exf_bulk_largeyeager04.F only :
1287      - change implementation for case where windspeed + 2. components wind-stress
1288        are read-in. AND use rhoConstFresh to convert evap.
1289    o pkg/seaice:
1290      - use correct EXCH_UV for wind-forcing (on A-grid).
1291      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1292        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1293    o pkg/exf:
1294      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1295      EXF_INTERPOLATION:
1296      - merge global_with_exf/code version of exf_interp_read.F
1297        to the main code ;
1298      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1299        reading the file ; Important: This options needs to be defined to recover
1300        previous code.
1301        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1302      - no longer loose real*8 precision along the way when using exf_iprec=64.
1303  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)  o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1304      - change discretisation of evp-solver in order to avoid another exchange
1305        (changes lab_sea) and clean up a little
1306      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1307        help the adjoint (this also changes the results slightly)
1308      - add a few "_d 0" where they had been missing in seaice_evp.F
1309      - cleaning up: remove unused seaice_calc_rhs.F
