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