4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o allows to specify vertical profile of vertical viscosity (viscArNr)
8    o pkg autodiff
9      autodiff_ini_model_io: comment out writing of grid information to netcdf
10      files, because at this time the grid fields are a bunch of zeros
11      (this is analogous to ini_mnc_vars.F)
12    o pkg seaice/autodiff:
13     left-over from removing the 3-time-level fields:
14     - small rearrangement of common blocks (SEAICE.h)
15     - fix field declaration in order to get meaningful output in
16       adseaice.*.nc (adcommon.h)
17    o pkg obcs:
18     - go through NH code only if nonHydrostatic=T
19     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
20     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obcields
21       => Update output of experiment seaice_obcs
22     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
23     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
24     - fix restart for useOBCSprescribe + useEXF
25    o pkg ctrl
26     - make obcs as control parameter work also with useSingleCPUio
27     - replace a few sny and snx by Ny and Nx to be consistent with
28       ctrl_set_globfld_x/yz.F
29    o pkg seaice
30     - re-introduce global field frWtrAtm for the case of
31       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
32     - catch the case of an empty filename in seaice_cost_init_fixed.F
33    o pkg ecco:
34     - small bug fixes in the_main_loop
35      . fix order of monitor arguments
36      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
37      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
38        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
39     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
40       imbalance diagnostics for wmean_h/sflux = 0
41     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
42     - catch the case of empty filenames in ecco_cost_init_fixed.F
43       and ecco_readparms.F
44     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
45       to make this statement meaningfull in ecco_cost_weights.F
46    o pkg zonal_filt:
47      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
48      - when using rStar, filter uVel*hFacW instead of uVel
49       (tested without topography: fix a Pb of growing instability with NLFS)
50    o pkg/aim/thsice:
51     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
52      (works as SST restoring)
53    o pkg/thsice:
54     -add specific parameter for salt restoring in slab mixed-layer
55       (by default equal to the temperature restoring)
56    
57    checkpoint61v
58    o pkg/kpp:
59     -add double diffusive contributions as a hack, turned off by default
60      for now, and the code can be excluded with a CPP-flag
61      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
62     -add a verification experiments to "vermix" to test this code
63    o pkg/mom_common:
64      Move computation of length scales to mom_init_fixed.F (avoid recomputation
65      at each time-steps*levels).
66    o pkg/layers:
67      Created a new package for computing volume fluxes in temperature or
68      [not yet implemented] density layers, e.g. for calculating residual
69      overturning circulations.
70    o pkg/diagnostics:
71      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
72    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
73    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
74      To avoid mixing type (RS/RL) of input/output array argument,
75      replace single mixed-type array with a pair from each type (RS/RL).
76    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
77      is now implemented for all pkgs (previously only done for the main pickup)
78    
79    checkpoint61u
80    o pkg/obcs:
81      - change OB?eta from _RS to _RL and put them into a separate commen block
82      - add code to read OB?eta from a file via obcs_prescribe_read: the code
83        compiles and does not destroy any other experiments, the data is read
84        properly, but the code is not tested in actual applications
85    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
86      create a meaningful unit attribute for the time coordinate variable
87    o pkg/ebm: add plenty of missing "_d 0" ;
88       update results of experiment global_ocean_ebm (fwd + adjoint tests)
89      Notes: several pieces of code only works for (very) specific set up
90       (domain size, lat range, etc ...); should be documented & stop if one
91       of those assumptions is not meet.
92    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
93       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
94          and offline_exf_seaice (seaicetd + adjoint).
95    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
96       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
97        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
98    o few changes to pass when compiling with strick checking of arguments
99       across S/R (allow to find few bugs in S/R calls).
100    o pkg/seaice:
101     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
102       2d-fields, for slightly better performance
103    
104    checkpoint61t
105    o pkg/seaice:
106     - remove unused variables in seaice_evp
107     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
108    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
109       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
110       each processor opens a different file (a fix from Matt).
111    o cg2d:
112       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
113       this reduces number of EXCH calls by 2 when using exch2.
114       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
115       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
116    o pkg/thsice:
117       add code for Near Infra-Red albedo (from Jeff)
118       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
119    o ini_model_io:
120       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
121       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
122       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
123    
124    checkpoint61s
125    o pkg/exch2 (exch2_rxN_cube*):
126       remove last BARRIER (no need to synchronise after getting data from shared
127       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
128    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
129      and generate new output (for the 2 tests) using default rotationPeriod.
130    o pkg/exch2:
131      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
132        (was already the case with AUTODIFF_EXCH2 defined)
133      - add bj in exch2 arrays and S/R.
134      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
135        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
136    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
137      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
138        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
139      - verification experiment natl_box.longstep
140    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
141      allow different versions of ifort (8 or 9) and different versions
142       of mpi (mpich or mpich2) to be used with the same optfile.
143      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
144       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
145    o pkg/seaice:
146      fix previous modif (3-level field removed) for old-pickup reading
147    
148    checkpoint61r
149    o pkg/seaice:
150     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
151      1. introduce fields for time step (N-1)
152      2. do not use levels 2 and 3 anymore (but keep them)
153      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
154         includes changes to pkg/thsice/thsice_get_velocity.F,
155         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
156         pkg/obcs/obcs_apply_uvice.F.
157     - completely remove code for leap-frog time stepping for second order
158       advection
159     - adjusted adjoint accordingly;
160       gradient checks have improved by an order of magnitude!
161    
162    checkpoint61q
163    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
164     - the boundary conditions along open boundaries are unclear, because the
165       associated masks are set to zero and are thus treated as closed when
166       applying the slip-boundary conditions.
167     - move initialisation of grid variables from seaice_init_varia to _fixed
168    o adding doc/diags_changes.txt
169    o model/src:
170      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
171       to avoid "_diags" naming if no relation to pkg/diagnostics.
172      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
173       file and only call PLOT_FIELD_XYZ if debugMode=T.
174      remove few PLOT_FIELD_XY calls outside initialisation.
175      remove few unnecessary BARRIER.
176    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
177      of salt_plume package in Southern Ocean
178    o pkg/thsice:
179     - fix hOceMxL in overlap (needed for sea-ice advection);
180       update output of experiment global_ocean.cs32x15.icedyn.
181    o pkg/seaice:
182     - make the (placeholder-)tracer IceAge a little more meaningful
183      by avoiding ridging of age due to convergent ice flow
184     - add diagnostics for surface temperature, atmospheric and oceanic
185       heat flux, and atmospheric and oceanic ice growth
186    
187    checkpoint61p
188    o eesupp (global_max & global_sum):
189     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
190     - remove starting & endding barrier (no longer needed)
191    o pkg/mdsio, writelocal:
192       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
193       (remove the STOP): uses shared buffer IO to store data from all threads
194       and then let master-thread write nThreads tiles.
195    o pkg/mdsio (read/write field):
196     - tiled IO done in 1 piece (all levels at a time);
197     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
198     - multi-threaded: allow to read/write local (non-shared) array
199       (was already working with singleCpuIO ; now works also without);
200       => no longer needs barrier call after reading a file (added inside
201       mds_read/write field).
202     - move barrier calls outside gather/scatter_2d to mds_read/write_field
203    o pkg/obcs/exf
204      - exf_getffieldrec.F: add a few ". _d 0" and
205                            add code to catch the case fldperiod = 0.  
206      - obcs_precribe_read.F: change if statements so that they match
207                              the variable type (_RL)
208      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
209        exf_iprec) as part of namelist EXF_NML_01
210    o pkg/mdsio:
211      - read/write tiled (local) files: read/write 1-level tile chunk at a time
212        (instead of segment of length sNx); expected to speed up tiled IO.
213    o pkg/exch2:
214      - take buffer copy from/to array out of S/R exch2_send/recv into new
215        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
216        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
217      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
218      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
219        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
220        including Topology header file (and common blocks).
221      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
222        remove 2nd exch call in exch2_s3d_rx (no longer needed).
223      - document S/R arg. list (+ update some comments)
224    o pkg/seaice:
225      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
226        temperature and humidity over sea ice based on climatological values.
227      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
228        of LSR (this change is expected to change the results slightly because now
229        it uses slightly difference moduli from the second last LSR solution, but
230        that is more consistent with the stress computations; this part of the code
231        is not tested in the verification experiments)
232      - fix diagnostics for flux of ice in case of B-grid
233      - turn strain rates eij and press into global fields within global
234        common block in SEAICE.h for more straighforward diagnostics
235      - fix diagnostics for principal stress components, press, zeta, eta
236        to give something meaning full
237    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
238      new output (all 4 tests) using default rotationPeriod.
239    o pkg KPP:
240      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
241      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
242        and normal grid from 1 to Nr)
243    o Fix computations of L4rdt in mom_calc_visc.F
244    o eesupp:
245      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
246      should be called before a "stop" if we know that all process are going
247      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
248    
249    checkpoint61o
250    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
251    o model/src/ini_curvilinear_grid.F:
252       compute angleSin/CosC when they are not read from a file
253    o pkg/seaice:
254       add pseudo time stepping for LSOR
255    o pkg/exch2:
256       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
257    o pkg/seaice:
258       Adding separate sea ice albedo, drag coefficients, and HO in Southern
259       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
260    o SingleCpuIO:
261       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
262    o pkg/seaice:
263       put exchanged variable in (local) common block for MPI+Multi-Threads
264       to work (necessary with exch1, and for now with exch2 too).
265    o verification: to get more experiments tested with mpi, mth and mpi+mth,
266      change tiling of:
267       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
268       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
269      update output of exp:
270       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
271       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
272      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
273                       (note: output.txt generated on faulks using only 1 tile)
274    o eesupp & mdsio (SingleCpuIO):
275     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
276       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
277       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
278     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
279     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
280       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
281    o pkg/exch2:
282     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
283       read parameter file "data.exch2" if it exists; otherwise try default regular
284       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
285     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
286       with new code (not to be used, just as a backup solution).
287     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
288       in utils/exch2/input.
289    
290    checkpoint61n
291    o eesupp & mdsio (SingleCpuIO):
292      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
293        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
294        receive real*4 array (instead of real*8) to read/write 32.bit files.
295        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
296         and remove new mapping S/R)
297    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
298      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
299        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
300        when using exch2. Add S/R to map global io-buffer to global model array.
301      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
302    
303    checkpoint61m
304    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
305      and add 3 other S/R for other types (R4,R8,RS).
306      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
307    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
308     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
309     - reduce number of macro definitions (keep only those which are used);
310       can always call directly the corrresponding S/R if needed.
311     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
312       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
313     Fixed wrong type of arg in:
314       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
315       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
316     To fix: global_sum of var in common block is wrong (multi-threaded) in:
317       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
318     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
319    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
320      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
321    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
322    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
323      edges are closed (zero depth); might happen with "blank tiles";
324      for now, disabled if using OBCS.
325    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
326      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
327    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
328      to reduce length of 1.D array print in STDOUT.
329    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
330      + use 48 tiles (16x8): this will allow to test "blank tiles".
331    o start to test MPI + multi-threaded (change testreport to skip tests
332      where number of tiles do not match).
333    o genmake2: add option "-omp" to turn on Open-MP ;
334      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
335    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
336      and keep the original tile numbering. Note: compatible with old
337      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
338    
339    checkpoint61l
340    o Overlaps had been forgotten in calculating ijk keys : fixed
341    o fix cyrus makedepend for gcc 4.4
342    o experiment fizhi-cs-aqualev20:
343      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
344      and generate new output. Note: new output is much closer to the old
345      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
346      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
347    o pkg/fizhi:
348     - change to avoid indices going deliberately over array-bounds
349     - remove unnecessary MPI stuff
350     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
351     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
352       does not go over array-bounds and therefore returns reliable output.
353     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
354       this S/R has 4 output arguments, which are used inside "get_alarm";
355       when it is called with the same variable "ndum" in place of several
356       output arguments, this produces weird side effect inside "get_alarm"
357      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
358       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
359       address) and produces error.
360    o tools/gemake2: (March 27-29 2009)
361      with option "-mpi": link *_mpi files from "MODS" dir (this is what
362      testreport does).
363    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
364    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
365       update lab_sea.lsr & lab_sea.salt_plume results
366    o pkg/seaice:
367      Major overhaul of the LSOR solver: change discretization from original
368      finite differences to finite volume. The old routine is still in the
369      file seaice_lsr.F and can be turned on with the CPP-flag
370      SEAICE_OLD_AND_BAD_DISCRETIZATION
371      Along with this change, the discretization of the strain rates is changed.
372      The same flag turns on the old discretization in seaice_calc_strainrates.F
373      All verification experiments with seaice are affected (except for
374      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
375      results by setting the above flag.
376      Further changes involve changes in defaults:
377      - ALLOW_FLOODING is defined and turned on by default
378      - SEAICEadvSnow = .true. is now the default
379      - SEAICEadvSalt = .true. is now the default
380      - SEAICEadvAge  = .true. is now the default
381      - SEAICE_clipVelocities  = .false. is now the default
382                                         (as per J. Zhang's recommendation)
383      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
384        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
385      - seaice_growth: replace computation of UG by a simple copy from wspeed
386    
387    checkpoint61k
388    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
389      seaice_lsr: fixed a few metric terms,
390                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
391                  add more debugging diagnostics
392      seaice_evp: removed superfluous many metric terms of FV discretization
393                  of stress divergence
394                  affects lab_sea, lab_sea.hb87
395      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
396                  of stress divergence for non-evp solver
397                  (this part is not tested anywhere)
398      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
399                  they were effectively only half slip
400                  affects lab_sea.hb87
401      updated all relevant verification experiments (except lab_sea//output_adm.txt
402        which was left over, but fails at level 7 & 6)
403    
404    checkpoint61j
405    o pkg/seaice: turn a few hard wired parameters into run time parameters
406    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
407      time in seconds as promised by the usints in seaice_monitor and exf_monitor
408    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
409      that are not cubed-sphere grids
410    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
411    o pkg/ctrl:
412      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
413    o non-hydrostatic (calc_gw.F):
414      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
415      update output of exp. global_ocean.cs32x15.viscA4
416    o remove backward compatibility for thetaMin,phiMin
417      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
418    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
419      interpolated wind field not only for curvilineargrid=.true., but also
420      for a rotated grid (rotateGrid=.true.)
421    o pkg/exf: add capability to bypass interpolation for runoff
422      by setting yet another CPP-flag
423    o eesupp/src, B-grid exchange:
424      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
425    o autodiff
426      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
427      allows to switch to single-prec common blocks;
428      corresponding switch occurs in tamc.h, integer isbyte
429      TAF store directivs "byte" and "kind" seem equivalent;
430      Most tamc.h have been updated correspondingly.
431    
432    checkpoint61i
433    o autodiff:
434      fix autodiff_sore/_restore indices for obcs
435      (spotted by I. Hoteit, M. Mazloff)
436    o pkg/autodiff, pkg/ctrl:
437      Add flag to reduce all tapelev I/O to single-prec.
438      In data.ctrl set
439        doSinglePrecTapelev = .TRUE.
440    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
441      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
442    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
443      real fresh water flux (not yet)
444    o pkg/mdsio & rw:
445     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
446     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
447    o pkg/flt:
448     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
449       init_fixed & ini_varia.
450     - clean-up & simplify linear interpolation S/R:
451       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
452     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
453     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
454     - add vert. coordinate & horiz. indices to output files.
455     - change vertical position in initial condition, from index to depth [m].
456     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
457       (easier to get to a curvilinear grid) ; delX,delY no longer used.
458    o pkg/ggl90: a few modifications:
459     - fix bottom boundary condition, and interpolation of KappaE
460       near top and bottom
461     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
462     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
463     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
464    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
465      (maintain temporary backward compatibility, until next checkpoint)
466    
467    checkpoint61h
468    o pkg/diagnostics with "periodic averaging diagnostics":
469      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
470    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
471    o pkg/obcs: fix loop ranges for balancing code
472    o pkg/flt:
473     - improve criteria for finding which tile owns a float.
474     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
475    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
476      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
477      with ocean biogeo)
478    o pkg/flt:
479     - do some cleaning and fix the restart ;
480     - add output.txt in flt_example/results to get this pkg tested.
481    o genmake2: add an EXTENDED_SRC option and flag.
482       for now, cannot be turned on on command line (only through genmake_local)
483    o pkg/mdsio: read/write vector:
484     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
485     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
486       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
487     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
488      (drop to 4 digits matching for grad). But this test does not look very
489      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
490    
491    checkpoint61g
492    o pkg/flt:
493      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
494       + make OPTIONS file more standard.
495      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
496      - fix _BYTESWAPIO CPP-Flag
497      - standard reading of file-parameter "data.flt"
498      - fix argument list of S/R FLT_RESTART
499      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
500    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
501    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
502      a still unfixed compiler/optimization bug
503    
504    checkpoint61f
505    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
506      update results of global_ocean.cs32x15.icedyn test.
507    o move getcon.F from model/src to pkg/fizhi.
508    o pkg/exf: add parameter for extrapolation of temp up to the surface
509       and option to prevent negative evap (in bulk_largeyeager04 only).
510    o Prather Advection scheme: fix tracer conservation for divergent flow
511      (e.g., when using NonLin Free-Surface).
512    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
513    o gmredi (Visbeck-variable-K):
514     - add more parameters to Visbeck-variable-K.
515     - use a 5 points average for dSigmaR in Visbeck-K calculation
516       (more "homogenous": same stencil and same weights as in dSigmaH)
517     - update output of ideal_2D_oce experiment.
518    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
519      (#undef REAL4_IS_SLOW)
520     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
521       coordinate variable
522     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
523       (surface forcing fields), removes some of the functionality
524     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
525     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
526       probably not all: copy _RS surface flux fields to RL field before
527       calling DIAGNOSTICS_FILL
528     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
529       real*4 (CALL EXCH_*_RS) versions.
530     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
531       (generate new output).
532    
533    checkpoint61e
534    o gmredi (Visbeck-variable-K):
535      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
536      - change computation of Visbeck-K where Slope > Smax :        
537        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
538        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
539    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
540      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
541    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
542    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
543      does not become too large (to avoid precision problems in implicit-diffusion
544      solver); update ideal_2D_oce output.
545    o pkg ggl90:
546      - in ggl90_cal.F: compute only one set of visc/diff, used to
547        step forward TKE/T/S/momentum
548      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
549        have Prandlt =1)
550    o gmredi (fm07):
551      - add lower limit on Transition layer thickness + lower limit on 1/lambda
552      - allow to set few more params from data.gmredi
553    o pkg ggl90:
554          - add missing sqrt(2) factor in computation of mixing length
555            scale in ggl90_calc.F
556            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
557    
558    checkpoint61d
559    o adjoint modifs
560      - adapt to new field rhoInSitu
561      - allow to revert from StoreDynVars2D, StoreDynVars3D
562        to individual fields
563        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
564    o store 3-D (in-situ) density in commom block (DYNVARS.h)
565     - save 1 rho computation.
566     - no longer modify T & S inland when using down_slope pkg.
567    o gad_som : allow to switch to SOM advection for T & S without corresponding
568      pickup files (using new S/R: MDS_CHECK4FILE).
569    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
570      (for useSingleCpuIO to work in multi-threaded)
571    o pkg/shelfice:
572     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
573       with SHELFICEtopoFile in data.shelfice
574     - move code for reading ice shelf topography and modifying hFacC into separate
575       subroutines of the shelfice package
576     - separate initialisation of "fixed" and "variable" variables
577     - kTopC is not (yet) replaced by kSurfC, although this is possible
578    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
579    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
580      and rename:
581      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
582      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
583    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
584    
585    checkpoint61c
586    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
587      to add mass source/sink of fluid in the interior (3-D generalisation
588      of oceanic real-fresh water flux).
589    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
590    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
591    o new pkg: down_slope
592      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
593      - presently, modify T & S inland (dwnslp_calc_rho.F).
594        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
595      - implementation for ocean in P-coords not tested.
596      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
597    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
598      (to facilitate conversion of oceanic pkg to p-coordinate).
599    o change FIND_RHO to FIND_RHO_2D :
600      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
601    o new pkg: cheapaml
602    
603    checkpoint61b
604    o exch2:
605      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
606      - no longer depend on the order sequence (N,S,E,W).
607      - 3rd exchange no longer needed (tested with 24 tiles).
608      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
609      - exch_UV_A-grid readily available (but not yet tested).
610      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
611      (both are no longer needed) in exch_uv: no effect in forward run; but
612       get truncation error differences with adjoint exch.
613    o exch2:
614     - change index-bounds storage (moved from target to local tile,
615       more intuitive this way) ; rename/remove some variables.
616     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
617    
618    checkpoint61a
619    o exch2/matlab-topology-generator:
620      fix bug in index bounds for N-S internal exchange (hard to tell if this
621      had any effect on the solution).
622    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
623      is exceeded
624    o testreport: modify syntax of awk, so that it works also with
625      awk, and not only with nawk and gawk
626    
627    checkpoint61
628    o autodiff
629      Change default for TAF usage by removing argument '-nonew_arg'
630      This changes TAF subroutine argument list (ordering of active var.)
631      Omission of this flag leads to incompatibility w.r.t. TAMC
632      To restore TAMC-compatibility, need following modifs:
633      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
634      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
635      Tested TAF version is 1.9.22
636      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
637    
638    checkpoint60
639    --->>> This is the last checkpoint for which generating the adjoint
640    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
641    --->>> by default.
642    --->>> Future checkpoints will ommit this flag by default.
643    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
644    o pkg/grdchk: Add gradient check to etan0 perturbations.
645    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
646    o pkg/autodiff: more flexibility in zeroadj.
647      model/src: modifying do_oceanic_phys.F accordingly.
648    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
649    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
650      special setup of gmredi for which the adjoint is stable
651      enough for parameter optimization.
652    o bridging the gap between eddy stress and GM.
653      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
654          along with a change in CPP option (now ALLOW_EDDYPSI).
655      -> when using GM w/ GM_AdvForm:
656          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
657          is applied either in the tracer Eq. or in momentum Eq.
658          depending on data.gmredi (intro. GM_InMomAsStress).
659      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
660      The key modifications are in model/src/taueddy_external_forcing.F
661      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
662    
663    checkpoint59r
664    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
665      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
666      fix option to read coriolis(@ cell-corner) from files with CS-grid.
667    o pkg/mnc: add some attributes to standard 1D-coordinate variables
668    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
669      mass points, when using mnc for output
670      - add runtime parameter (missing_value, missing_value_int) to override
671        default (which is the value of getcon('UNDEF'))
672    o pkg/mnc: prepare mnc for the actual use of missing values with the
673      diagnostics package: small fix in mnc_cw_readwrite.template and more
674      initialisation of never used fields
675      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
676      versions
677    o pkg/thsice/thsice_ini_vars.F added default initial values so that
678      thermodynamics sea ice solver does not blow up when some initial fields
679      are missing.
680    o move from external_forcing_surf.F to ini_forcing.F
681      the p-coord. hack consisting in using pLoad to set phi0surf ;
682      update output of tutorial_global_oce_in_p (affected @ truncation level).
683    o Freshen up a bit hs94.1x64x5, notably:
684      remove rotationPeriod and tRef=5*0. (adjoint only), and add
685      exactConserv=.TRUE.
686    o pkg/generic_advdiff:
687      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
688      applies to files where Temperature & Salinity 2nd Order moments are used.
689    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
690      this uses a dynamically allocated internal state data structure
691      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
692      and requires a fortran 90 compiler
693    
694    checkpoint59q
695    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
696       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
697    o Refresh tutorial_global_oce_biogeo, notably:
698      - change bathymetry (put back seamounts in ACC, use hFacs)
699      - change EOS (POLY3 --> JMD95Z)
700      - use Bryan-Lewis vertical diffusivity
701      - use multidimensional advection
702      - remove old virtual virtual in dic pkg, now done through ptracer pkg
703      - change a couple of parameters in dic pkg
704    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
705    o pkg/obcs: change default to OBCSfixTopo = .true.,
706      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
707      - replace "debugMode" with "debugLevel .GE. debLevB"
708    o implementation of TAF directives for gchem,cfc,dic
709    o remove "exp5" (replaced by tutorial_deep_convection).
710    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
711      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
712      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
713      --> changes results in exp4, seaice_obcs
714    o tutorial_deep_convection :
715      update the set-up and increase resolution and domain size ; start
716      from pseudo initial conditions = output at t=120mn in order to see
717      something happening when running testreport.
718    o pkg/seaice: add os7mp as an advection scheme
719                  add check for advection schemes
720                  add a flag for restoring T and S underneath sea ice
721    o pkg/my82: add netcdf-support and diagnostics
722    o thsice pkg:
723      - Now hsMax limits snow height by turning it into ice following
724        flooding scheme (and now conserving energy)
725      - Slight rewriting of the formula in thsice_calc_thick.F
726      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
727      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
728    
729    checkpoint59p
730    o gchem / dic / cfc :
731      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
732      - add new parameter files: "data.dic" & "data.cfc" ;
733      - various re-arrangement in initialisation & header file ;
734      - fix tutorial_global_oce_biogeo for multi-threaded test.
735    o pkg/dic: test for "pickup_dic" file when restarting ;
736      if no pickup-file, can restart with a re-initialised pH (same as it did
737      before) providing pickupStrictlyMatch is set to False.
738    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
739      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
740    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
741      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
742    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
743     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
744       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
745    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
746       scheme to use for vorticty-term ;
747     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
748       (with default selectVortScheme, return to original discretisation)
749     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
750    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
751    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
752      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
753      also fix diagnostics VISCAHW & VISCA4W.
754    
755    checkpoint59o
756    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
757    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
758      move a few statemens out the main loop into separate loops
759    o pkg/shelfice:
760      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
761        (kg/m^2/s), does not break tests, because in verification/isomip,
762        rhoConstFresh=rhoConst (by accident)
763      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
764      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
765        new file model/src/seawater.F, so that they are available for all pkgs.
766      - convert potential temperature into in-situ temperature. This changes the
767        isomip tests => update tests
768    o add a flag writePickupAtEnd (default=true) to be able to suppress
769      writing a pickup at the last timestep
770    o tools/mpack-1.6 :
771      - disable automake (not working) and autoconf (not needed).
772      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
773        also cleaner with much less compilation warnings.
774    o pkg/profiles:
775      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
776      (for "less than 32 characters name" compiler requirement)
777    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
778      conditions that have a different sampling frequency than S/T/U/V obcs
779    o pkg/diagnostics (stats-diags):
780      - fix global Min/Max in case 1 processor get only empty tiles
781    o genmake2: replace (4 times)
782         make genmake_tc_1.o >> genmake_warnings 2>&1
783      with
784         COMM="$CC $CFLAGS -c genmake_tc_1.c"
785         echo $COMM >> genmake_warnings
786         $COMM >> genmake_warnings 2>&1
787      to make genmake2 always see the value of CC as specified in the optfile.
788    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
789      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
790      - modify verification advect_cs test to test SOM-advection on CS-grid.
791    o pkg/ctrl:
792      - Rewrite of ctrl_map_ini_ecco.F,
793        introducing a generic routine (ctrl_map_ini_gen.F).
794      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
795    
796    checkpoint59n
797    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
798      number in dedicate array "hdiag":
799      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
800        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
801      - many small changes (integer format) for large number of diagnostics
802      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
803        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
804    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
805      usingSphericalGrid, this allows to define the rotated grid coordinates
806      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
807      geographical coordinates according to the inverse of the rotation defined
808      by the Euler angles, so that Coriolis parameter and online-interpolation by
809      exf works with the geographical coordinates on XC/YC/XG/YG.
810      Naturally, this feature does not work with all packages, so some
811      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
812      profiles), because there the coordinates are assumed to be regular
813      spherical grid coordinates.
814    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
815      - introduce isopycnal diffusion coefficient control.
816    o tools/adjoint_options:
817      - additional control vector components.
818    o pkg/mnc: have mnc create marginally meaning full coordinate variables
819      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
820    o pkg/mypackage:
821      - add example of read/write pickup for state-var ;
822      - add entry points to the main code for state-vars diags & write-pickup.
823    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
824      transitions for useExfYearlyFields
825      - add new subroutine that determines the file to read from for
826        use*YearlyFields = .TRUE. and .FALSE.
827      - add a verification experiment to global_with_exf that tests
828        useExfYearlyFields with USE_EXF_INTERPOLATION defined
829    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
830      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
831      subroutines (which could be generated from a template, because they are
832      almost identical), for now they are included in obcs_prescribe_read.F for
833      simplicity
834    o pkg/exf:
835      - add a little more diagnostic to exf_interp_read (in analogy to
836        mds_read_field, can be turned off with debugLevel < debugLevA=1)
837      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
838        ugly but fast by unrolling short inner loops, inserting a unroll=8
839        directive in routine lagran, and splitting a loop and making do while the
840        outermost loop (the latter requires the intoduction of index arrays)
841    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
842    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
843      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
844    o verification/seaice_obcs: updated for restart test and latest options
845    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
846      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
847      for now this is only available for the C-grid code and also within
848      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
849    
850    checkpoint59m
851    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
852      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
853    o gad_som : fix flux output (& diagnostics) to have same units as other  
854      advection scheme fluxes (was previously multiplied by deltaT).  
855    o added verification/seaice_obcs both to test seaice open boundaries
856      and to provide an example matlab scrpt for generating them
857    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
858    o pkg/salt_plume: clean up salt_plume_frac.F to
859      remove redundancy in PlumeMethod 1 and 4
860    o pkg/kpp: added saltplume diagnostics
861    o pkg/obcs and pkg/seaice:
862      - do not set uice and vice to zero when OB*icefile are unspecified
863      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
864      - moved seaice tracer obcs after call to seaice_growth
865    o pkg/salt_plume: added various options for salt plume depth
866      criterion and for vertical distribution of the salt
867    
868    checkpoint59l
869    o pkg/ptracers: new version of ptracers pickup:
870      read meta file and write only fields which are needed to restart.
871      ( same logic as main pickup file ; also using pickupStrictlyMatch )
872    o pkg/seaice:
873      - add timescale for melting due to warm mixed layer as a means of
874        setting SEAICE_availHeatFrac more conveniently
875      - add a CPP-flag/runtime parameter check for flooding algorithm
876      - reformulated availHeat in seaice_growth.F to be independent of AREA
877    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
878      unit changes
879    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
880    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
881      SX vector computer.
882    o pkg/seaice:
883      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
884        seaice forcing fields can now be read only through pkg/exf
885      - removed some unused halos
886    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
887    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
888      or U/VICE from U/VWIND before computing U/VSTRESS
889    
890    checkpoint59k
891    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
892      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
893    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
894      all experiments pass when compile with un-initialised var. checking option.
895    o added pkg/salt_plume
896    o script to test restart (for now, in MITgcm_contrib/jmc_script)
897    o pkg/seaice: new read/write pickup version.
898      read meta file and write only fields which are needed to restart.
899      ( same logic as main pickup file ; also using pickupStrictlyMatch )
900    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
901    o lab_sea.hb87: modify the domain & update output.hb87.txt :
902      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
903      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
904      process. Fixed here by closing the domain at the Northern boundary.
905    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
906    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
907      a set of consecutive levels in/from a 3-D array.
908    o pkg/ptracers:
909      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
910      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
911    
912    checkpoint59j
913    o in pkgs: dic, obcs, offline, rbcs:
914      standard way to compute coeff. for time interpolation between 2 time reccords
915      which retains full precision (& make results less dependent on compiler).
916      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
917    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
918      packages instead of reading ice cover and wind speed separately
919    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
920     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
921      to allow to compile customized code before the update)
922    o cleaning-up:
923      - fix CPP instruction syntax in pkg/obcs
924      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
925        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
926      - fix some threads issue in IO parts.
927    o pkg/dic:
928      - add tons of "_d 0" (--> much better testreports !)
929       and then update outputs of tutorial_global_oce_biogeo
930    o pkg/mom_fluxform:
931      add a special version of momentum advection intended to conserve momentum
932      next to a bathymetry step or a coastline edge. (default = off = #undef)
933    o new read/write pickup version:
934      - for now, only implemented for main (mdsio) pickup file.
935      - write out only what is needed to restart; merge pickup_nh , pickup_ph
936        and main pickup together.
937      - read meta file; read only what is needed to restart; stop if a field
938        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
939        if it make sense (even if the restart is not perfect).
940      - if no meta file, assume that pickup to read corresponds exactly to
941        a pickup that would currently be written.
942      - read pickup written in the old format (until checkpoint59i) if it
943        recognizes an old meta file (no field-list).
944      - add a meta file in exp. which starts from a pickup: 2 cases:
945        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
946         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
947        b) a meta file describing the content of the associated pickup file
948         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
949    o pkg/mdsio & pkg/rw:
950      - new routine to read a meta file ; new set of routine to read
951        Multiple-fields file (with meta file).
952    o added open boundary conditions capability for seaice
953        HSNOW, HSALT, UICE, and VICE
954    
955    checkpoint59i
956    o adjoint:
957      * fix multiDimAdvection adjoint
958        (partial recomputation problem by TAF for fVerT(:,:,kDown)
959        and comlev1 size definition (maxpass vs. max. number of tracers)
960      * verification/global_ocean.90x45x15 adjoint now tests
961        NLFS and multiDimAdvection using DST3 (=30)
962      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
963    o pkg/kpp: add "_d 0" to real constant (if missing);
964      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
965      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
966    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
967      for internal parameters related to restart process (formerly from PARAMS.h)
968      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
969    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
970      as argument. (only atm2d & obcs write_pickup have not yet been updated)
971    o pkg/monitor:
972      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
973      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
974      - account for deep Atmosphere factor and density factor (anelastic)
975    o added open boundary conditions capability for seaice HEFF and AREA
976    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
977      thermodynamics
978      - requires a little reorganization, which affects the testreport results
979        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
980        so that now the conservative form is tested
981      - add a few comments
982    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
983    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
984    o add new diagnostics to seaice: advective, diffusive fluxes (only for
985      multidim-advection, for scheme 2 they are not filled) and transports,
986      thermodynamic growth rates
987    o change units of EmPmR (inside the code, + within coupling interface)
988      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
989      Affects results @ truncation level (cg2d match) and update output of
990       experiments: lab_sea(6), global_ocean.90x40x15(10),
991      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
992      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
993      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
994      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
995    
996    checkpoint59h
997    o pkg/exf:
998      - improve vectorization by moving if-statement out of loops in
999        exf_mapfields, exf_radiation
1000      - exf_bulkformulae.F: introduce 2D fields and vectorize code
1001    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
1002    o testreport:
1003      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
1004        monitor & update offline_exf_seaice exp. output.
1005      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
1006    o pkg/seaice:
1007      - bug fix in the evp solver: boundary conditions were affected be
1008        masking of zMax/zMin (changes results)
1009      - minor bug fix in boundary conditions in seaice_calc_strainrates
1010        (changes results for no_slip)
1011      - seaice_lsr.F: make interpolation of eta dependent on boundaries
1012      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
1013      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
1014        stress formulation and no-slip boundary conditions
1015    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
1016      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
1017    o pkg/seaice: a first HSALT time stepping equation has been checked in
1018    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
1019      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
1020      without requiring DO-IF statements
1021    o pkg/thsice:
1022      use continuous power-law function for partition of energy between lateral
1023      melting/freezing and thinning/thickening ; old code using step function
1024      still available with #undef THSICE_FRACEN_POWERLAW
1025      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
1026    o testreport: change AD testing : check against results/output_adm.txt
1027      using same scripts as for forward test.
1028    
1029    checkpoint59g
1030    o adjoint testing: in preparation for changing testreport:
1031      - output format: cost and grad written on separated lines
1032      - ad output results in directory "results" (instead of "results_ad")
1033    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
1034    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
1035    o pkg/ecco: allow user defined cost function contributions
1036    o testreport:
1037      Allow to choose (per experiment) the list of tested output variables
1038       and the main variable (used to issue a pass/FAIL ) ;
1039      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
1040      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
1041      Also modify printing of summary:
1042       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
1043       b) echo the list of tested variables in the individual summary.txt of
1044          each experiment.
1045    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
1046      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
1047      (but still depend on the tile decompostion of the domain).
1048    o pkg/seaice: change a discretization detail to make the B-grid code
1049      "more symmetric". This change is likely to remove all "ridges/leads" that
1050      where quasi-aligned with the grid in B-grid solutions. It may also be
1051      the solution to the stress coupling issues with the B-grid.
1052    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
1053      remove .cvsignore from input dir. (since testreport no longer run here).
1054    o pkg/thsice:
1055     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
1056     - fix reshaping of sea-ice just after advection:
1057       melt all the ice only if ice-volume is too small.
1058     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
1059       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
1060     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
1061    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
1062      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
1063    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
1064      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
1065      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
1066      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
1067      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
1068      -> update output.txt
1069    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
1070     this affects truncation error: -> update output.txt of exp:
1071      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
1072      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
1073    
1074    checkpoint59f
1075    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
1076    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
1077      a bounded range (in forward mode)
1078    o pkg/ecco, ctrl, autodiff and mom_common:
1079     internal parameter controls, completements of implementations
1080    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
1081    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
1082      (not seem any difference in testing results).
1083    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
1084       at face corners.
1085    o pkg/generic_advdiff:
1086     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
1087      loop range indices for computing vertical advection tendency
1088      and do the calculation in the interior only (no overlap) ;
1089      for now, only implemented for SOM advection (to save CPU time).
1090     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
1091    o exch2 adjoint
1092      First set of changes:
1093      - add exch2 hand-written adjoint templates
1094      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
1095        This will require cleanup in pkg/autodiff/*.F
1096        (changed routines currently kept separate in verif. code/)
1097      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
1098        that used to hide exch2 or cubed-sphere specific code
1099        (commented via 'cph-exch2')
1100    o pkg/seaice
1101      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
1102    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
1103       output of global_ocean.cs32x15.thsice .
1104    
1105    checkpoint59e
1106    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
1107      for B-grid vector (not yet tested) and C-grid vector (<- only used
1108      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
1109    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
1110      (#ifdef ALLOW_SALT_PLUME)
1111    o gather_2d/scatter_2d: removed halo regions
1112    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
1113      scheme and the corresponding test case (under front_relax dir). For now,
1114      only available with Skew-flux form and not yet tested in realistic set-up.
1115      adjoint: store directives updated, but gradient checks deteriorated,
1116      so maybe GM/Redi adjoint is now broken.
1117    o seaice adjoint
1118      * add AREA, HEFF, HSNOW as control variable
1119        (should not change lab_sea results)
1120      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
1121    o pkg/seaice:
1122      * added computation of saltFlux in seaice_growth;
1123        For time being, sea ice salinity is assumed constant
1124        contribution of snow flooding to freshening of sea ice is neglected.
1125        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
1126        defaults to 0.0 in order to maintain backward compatibility.
1127        Typical values for SEAICE_salinity are 4 to 10 g/kg.
1128      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
1129      * added SEAICE_availHeatFrac, which specifies fraction of surface level
1130        heat content used to melt or grow ice
1131      * commented out cap of HICE: it helps keep ice thinner
1132      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
1133      * applied OBCS T/S mask to HEFFM sea ice mask
1134    
1135    checkpoint59d
1136    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
1137     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
1138     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
1139    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
1140     and change default value of parameter "GM_Small_Number";
1141     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
1142       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
1143       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
1144    o pkg/ecco: cost function when applying pkg/smooth to controls
1145    o pkg/ctrl: add forcingPrecond run time parameter
1146    o pkg/seaice:
1147     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
1148     - fix bug in metric terms of u-equation in LSR solver (implicit part),
1149       changes verification/lab_sea
1150     - rearrange implicit part of u-equation in LSR solver to make it easier to
1151       read, understand, and debug. This causes changes at the truncation level.
1152     - fix (serious) bug in the boundary conditions (sign error in the implicit
1153       part) of the LSR solver. Changes all LSR results.
1154     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1155       is initilized with small values - does not change lab_sea results.
1156     - added HsnowFile initialization capability
1157    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1158     initialization of pkg/smooth and application to control vector
1159    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
1160    o dependencies: pkg/profiles requires pkg/cal
1161    o pkg/profiles:
1162     - added option ALLOW_PROFILES_GENERICGRID
1163         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1164         that interpolation information (grid points and coefficients) is provided
1165         within the netcdf input files.
1166         -> sample matlab scripts can be found in MITgcm_contrib/gael
1167         that allow you to prepare netcdf input files.
1168     - also modified: cleaner include statements, cleaner error print statements,
1169       cleaner stops when error, and more tests of the netcdf input files consistency.
1170    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1171    o pkg/seaice:
1172     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1173       requires a new routine: seaice_diagnostics_fill.F
1174     - make sure that seaice does not move if not forced (pressure replacement
1175       method, Hibler and Ip, 1995), changes results
1176     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1177     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1178       It is turned off by default (=-1.), because it changes the results.
1179     - make it possible to read AREA from a file, too.
1180    
1181    checkpoint59c
1182    o add S/R and diagnostics for oceanic mixed-layer depth
1183    o move GMRedi call after all vertical mixing schemes (including KPP)
1184    o pkg/thsice:
1185     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1186      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1187    o pkg/obcs:
1188     - bug fix for balance code
1189    o pkg/seaice:
1190      - allow values of SEAICE_elasticParm > 1
1191      - add new parameter SEAICE_evpTauRelax as an alternative
1192        to SEAICE_elasticParm
1193      - make lsr boundary conditions free slip (by default), changes result
1194      - add code for no slip boundary conditions for lsr
1195      - set minimum of zeta to zero (and not 4e8) (changes results)
1196      - add a cap on AREA after advecting AREA if seaice_growth is not called
1197    o change calculation of Visbeck K:
1198      - no longer depend on tapering scheme; instead, compute slope (limited
1199        by GM_maxSlope). this is equivalent to what was comuted before with
1200        clipping or linear tappering.
1201      - fix vertical averaging (wrong by 1/2 level)
1202      - leave the old version (but will not be maintained) within
1203        #ifdef OLD_VISBECK_CALC / #endif
1204      - update output of exp. ideal_2D_oce
1205    o change error catch in calc_r_star to improve vectorization
1206    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1207      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1208    o adjoint:
1209      Re-organized adjoint checkpointing according to Matt Mazloff
1210      (but with modifs/completions/cleanups)
1211      Storing is now bundled into large arrays to optimized I/O
1212      (and second step in cleanup of the_main_loop)
1213    
1214    checkpoint59b
1215    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1216      - export/import (between ocean & coupler) fields needed for ocean DIC.
1217    o pkg/seaice:
1218      - get rid of three more exchanges seaice_calc_viscosities (required
1219        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1220      - bug fix in seaice_ocean_stress (update of lab_sea required)
1221      - reduce loop boundaries to necessary minimum also in seaice_evp
1222      - go back to the old way of computing deltaC/Z as the adjoint likes that
1223        better
1224    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1225      passive tracer to an Age Tracer) + update output.txt
1226    o pkg/exf:
1227      - implement A-grid / C-grid selection for wind-stress input files.
1228      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1229      for now, in exf_bulk_largeyeager04.F only :
1230      - change implementation for case where windspeed + 2. components wind-stress
1231        are read-in. AND use rhoConstFresh to convert evap.
1232    o pkg/seaice:
1233      - use correct EXCH_UV for wind-forcing (on A-grid).
1234      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1235        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1236    o pkg/exf:
1237      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1238      EXF_INTERPOLATION:
1239      - merge global_with_exf/code version of exf_interp_read.F
1240        to the main code ;
1241      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1242        reading the file ; Important: This options needs to be defined to recover
1243        previous code.
1244        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1245      - no longer loose real*8 precision along the way when using exf_iprec=64.
1246    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1247      - change discretisation of evp-solver in order to avoid another exchange
1248        (changes lab_sea) and clean up a little
1249      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1250        help the adjoint (this also changes the results slightly)
1251      - add a few "_d 0" where they had been missing in seaice_evp.F
1252      - cleaning up: remove unused seaice_calc_rhs.F
1253    o pkg/exf: some cleaning-up:
1254      - change various "constants" into runtime parameters
1255      - cleaned-up Large&Yeager04 routine which should eventually
1256        replace exf_bulkformulae.F (changed names of S/R and CPP)
1257        and merged various ALLOW_ATM_WIND options
1258     only used with thsice pkg (in thsice_get_exf.F):
1259      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1260        which are used when useStabilityFct_overIce=TRUE (= the default)
1261      - change default values of ice & snow emissivity and scale downward LW
1262        by ice & snow emissivity.
1263    o pkg/thsice:
1264     fix few little problems, in thsice_calc_thickn.F:
1265      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1266      - melt only laterally if hIce < hThinIce (as the comments say)
1267      and in thsice_extend.F:
1268      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1269      - start to form ice as soon as the minimum ice-volume is reachable.
1270     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1271      and cpl_aim+ocn
1272    o pkg/kpp
1273     - move computation of surface related input fields to KPP into a new
1274       subroutine kpp_forcing_surf.F
1275     - remove wrong (within bi,bj loops) EXCH calls.
1276     - little cleaning (add argument myThid in last position, cvs header ...)
1277     - for now, fix conservation problem by exchanging KPPviscAz (may not
1278       be the best fix)
1279    o pkg/seaice
1280     - check for inconsistent evp parameter/cpp-flag combination
1281     - remove leftover errIO flat for obsolete name list error handling
1282    o OpenAD
1283     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1284    
1285    checkpoint59a
1286    o pkg/seaice: some parameter clarifications and a little bit of clean up
1287    o pkg/thsice: rename run-time parameters:
1288       himin       -> hIceMin
1289       himin0      -> hThinIce
1290       hihig       -> hThickIce
1291       i0          -> i0swFrac
1292       transCoef   -> bMeltCoef
1293       frac_energy -> fracMelting
1294      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1295       with default values (for now) that do not change the results.
1296      remove old version of thsice vars advection in pkg/seaice.
1297    o in FFIELDS.h:
1298      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1299      - make pLoad & sIceLoad always available (but still only used if
1300         ATMOSPHERIC_LOADING is #define).
1301    o pkg/kpp: replaced _KPP_RL with _RL
1302    o bug fixes for vertical diffusivity computations when both KPP and
1303        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1304        are no longer updating the vertical diffusivity array
1305        (passed as argument) but are (re-) setting those arrays.
1306    o pkg/seaice: fix bug in evp solver, while doing that
1307      - change (improve?) discretization of stress computations for both
1308        cgrid-lsr and evp solver
1309      - add a new routine to compute strain rates
1310      - the above changes lab_sea results
1311      - add no slip conditions for evp solver (off by default), lsr-version
1312        may follow
1313      - fix exchange for shear at Z-points (does not change lab_sea)
1314      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1315        (to force the user to pick a time step since there is not "safe" way
1316        of choosing it)
1317      - add principal stress diagnostics
1318      - rearrange fields for evp a little to avoid having to call a: too many
1319        exchanges and b: exchanges for stress trensor components which we do
1320        not have.
1321      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1322        of evp, complete rewrite for lsr case (latter is does not yet work
1323        in all cases)
1324    o pkg/kpp: add code to have mixing in shelf ice caverns
1325      - add myThid to all kpp routines (long overdue)
1326    
1327    checkpoint59
1328    o pkg/exf:
1329      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1330        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1331      - move exf header files from lower_case.h to UPPER_CASE.h ;
1332        add missing cvs Header & Name
1333      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1334      - add namelist param. selectStressGridPosition, exf_monFreq
1335      - retire many _CLIM routines, and remove data.exf_clim
1336        + params moved to data.exf
1337        + climsst, climsss now handled by exf_set_gen, i.e.
1338          climss?period=0 refers to constant field,
1339          climss?period=-12 to monthly forcing
1340      - split up namelists in data.exf
1341    o pkg/seaice:
1342      - remove seaice_exch and seaice_exch_uv
1343      - remove superfluous exchange of theta
1344      - add myThid to seaice_budget_ocean/ice
1345      - add new interface for atmospheric wind forcing (C-grid only)
1346        + new routine
1347        + two new field (taux, tauy for stress over ice)
1348        + removed one global field (DAIRN) for C-grid case only
1349    o pkg/thsise
1350      - 2nd set of modifs for thsice adjoint in conjunction with exf
1351    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1352    
1353    checkpoint58y_post
1354    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1355      vertical diffusivity, similar to that in MOM4; turned on using
1356      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1357      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1358    o Added capability for 3D specification of background vertical diffusion
1359      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1360      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1361      "data" file that contains the 3D vertical diffusivity coefficients.
1362    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1363      - add code within pkg thsice to advect & diffuse sea-ice fields
1364      similar to (and will replace) what has been added in  seaice_advdiff.F,
1365      but: - conserving Mass, Heat & Salt.
1366           - better when using non-linear advection scheme (not yet fully tested)
1367           - can also be used in atmospheric set-up (for now, only the diffusion).
1368    
1369    checkpoint58x_post
1370    o IO option for global-file compact format:
1371      - add options when generating topology (utils/exch2/matlab-topology-generator)
1372      - add I/O capability (pkg/mdsio).
1373      - adapt utils/matlab/rdmds.m to read this format.
1374      for now long-line format not yet supported by pkg/mdsio (& exch2).
1375    o shelfice: add a few diagnostics
1376    
1377    checkpoint58w_post
1378    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1379      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1380      (and replace horiVertRatio in NH code).
1381      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1382                         and tutorial_plume_on_slope (sensitive to truncation)
1383    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1384      directly to drive seaice model (C-grid only)
1385    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1386     - reintroduce computation of wind from stress,
1387     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1388       mass points to avoid tau = 0
1389     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1390    o rdmnc.m: make it work with "global" files created with gluemnc
1391    o rdmnc.m : some improvements in dealing with singleton dimension
1392      (tested on all testreport mnc output files).
1393    o genmake2: disable pkg/profiles if netcdf test fails.
1394    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1395    o move call to cal_readparms up to make calendar parameters/variable available
1396      to all packages
1397    
1398    checkpoint58v_post
1399    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1400      useDynP_inEos_Zc tested.
1401    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1402    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1403      and portions thereof.  See read_cs.txt for description and examples.
1404    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1405      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1406      following the great-circle arc between those 2 points.
1407    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1408      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1409    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1410     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1411     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1412     - still needs work (not working with some options ; efficiency to improve)
1413       and serious testing.
1414     - use this scheme for temperature & salinity in 2 advection test exp.:
1415       advect_xy & advect_xz, respectively.
1416    
1417    checkpoint58u_post
1418    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1419    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1420    o testreport: add option "-skipdir" to skip some test.
1421    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1422      momentum calculation.
1423    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1424    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1425      remove checkpoint.F and the_correction_step.F (no longer used);
1426      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1427    o add option (linFSConserveTr) to correct for tracer source/sink due to
1428      Linear Free surface
1429    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1430    o pkg/thsice: fix reading mnc-pickups
1431    
1432    checkpoint58t_post
1433    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1434    o pkg/mdsio:
1435     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1436       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1437       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1438     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1439     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1440       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1441     - new S/R (to replace MDSWRITEMETA), which allows to write more
1442       informations (variable names, time ...) to meta files.
1443     - modify rdmds.m to give back the meta file content.
1444    o pkg/diagnostics: change vertical interpolation to be safer, and more
1445       flexible (define p-levels to interpolate to in data.diagnostics);
1446      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1447       diagnostic pointer.
1448    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1449    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1450    o fix multi-category seaice:
1451     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1452       SEAICE_MULTICATEGORY
1453     - fix short wave heat flux
1454    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1455       and allow to use EVP solver. Change forward lab_sea: test both EVP
1456       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1457    o Initial check-in of lab_sea adjoint
1458      (very similar to natl_box_adjoint/code_seaice)
1459      * used C-grid and EVP solver
1460      * used KPP, GM/Redi
1461      * uses inAdExact=.TRUE.
1462      * gradient checks fail for both ADM and TLM
1463        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1464        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1465        issue is related to forward mismatch between g77 an ifort
1466    o pkg/seaice: overhaul of thermodynamics
1467     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1468     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1469     - move a few global fields out of SEAICE.h into seaice_growth.F and
1470       make them 2D (FICE/QNETO/ ...)
1471     - remove FO (it is the same as QNETO)
1472     - introduce a few local fields to avoid modifying external fields such
1473       as atemp, etc.
1474    
1475    checkpoint58s_post
1476    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1477      changed exf_set_gen.F so that
1478        genperiod=0 means input file is one time-constant field and
1479        genperiod=-12 means input file contains 12 monthly means
1480    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1481      this affects truncation error ; generate new output file for exp. which
1482      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1483        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1484        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1485        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1486        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1487        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1488    o start implementation of deep-atmosphere and anelastic formulation
1489    o verification: remove 2nd copy of input files and use script "prepare_run"
1490      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1491    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1492    o profiles: fix for multithreaded case
1493    
1494    o diagnostics: rename few diags:
1495      s/'PRESSURE'/'RCENTER '/g
1496      s/'TICE    '/'oceFreez'/g
1497      s/'TAUX    '/'oceTAUX '/g
1498      s/'TAUY    '/'oceTAUY '/g
1499      s/'SWFLUX  '/'oceQsw  '/g
1500      s/DIFx/DFxE/g
1501      s/DIFy/DFyE/g
1502      and add few ocean-forcing diagnostics:
1503      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1504    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1505      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1506      as actual snow thickness.  It now refers everywhere to effective snow
1507      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1508    
1509    checkpoint58r_post
1510    o modifications to pkg/seaice/growth.F, which change results of
1511      lab_sea experiment: fixes pertain to melting snow over open water, to
1512      masking EVAP under sea ice, and to using the correct AREA variable for
1513      computations of EVAP, PRECIP, HSNOW, and GHEFF
1514    o add ability to read bathy, salt, and theta using MNC (off by def)
1515    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1516      both are turned off by default and do no change any results
1517    o seaice advection with pkg/thsice: a step toward the use of non-linear
1518      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1519    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1520      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1521      in natl_box (affects results @ truncation level: update output.txt)
1522    o multi-threading and IO:
1523      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1524      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1525        (needed to work with SingleCpuIO): tested in all verif. exp.
1526    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1527      affects the results (but none of the verification test uses this scheme).
1528    o Adding some pkg/diagnostics capability to pkg/seaice
1529      (will certainly be subject to changes)
1530    o ctrl: adding new control variables:
1531      lwflux, lwdown, evap, snowprecip, apressure, runoff
1532    
1533    checkpoint58q_post
1534    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1535      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1536      high_res_cube configuration by 4% on Columbia.
1537    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1538      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1539      dynamical allocation (seems to work in multi-threaded).
1540    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1541      single CPU io) so that TAF does not have to see EESUPPORT.h
1542    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1543    
1544    checkpoint58p_post
1545    o obcs: stop if obcs is used with useCDscheme = .true.
1546    o shelfice:
1547     - fix a sign error so that no slip at shelfice interface works
1548     - remove stop for combination non-hydrostatic code and shelfice. That does
1549       not mean, that the results are correct, but at least they are numerically
1550       stable
1551    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1552    o added adjoint exch routined for all exch*3d* routines
1553      and updated flow directives
1554    
1555    checkpoint58o_post
1556    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1557      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1558    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1559      and clean-up reading/writing of pickup files.
1560    o fix local version of read/write pickup (NH part) in rotating_tank/code
1561    o simplify EXCH interface:
1562     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1563     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1564    o added the regrid package
1565    o shelfice:
1566     - add a simple boundary layer scheme to reduce noise
1567     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1568    
1569    checkpoint58n_post
1570    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1571       local variable (not in common block).
1572    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1573      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1574      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1575        to work with SingleCpuIO.
1576    o add "_d 0" to real constant of pkg/cfc subroutines ;
1577       update exp. cfc_exemple & tutorial_cfc_offline output files.
1578    o multi-threading and IO:
1579      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1580        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1581      - barrier before and after reading.
1582      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1583      - avoid using MDS_WRITELOCAL for LAND pkg output.
1584      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1585        common-block variables ; Allows multi-threading with master-thread IO.
1586    o change default MAX_NO_THREADS from 32 to 4 ;
1587      and stop cleanly when MAX_NO_THREADS is too small.
1588    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1589    
1590    checkpoint58m_post
1591    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1592       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1593    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1594       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1595       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1596    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1597        add MITgcm_tutorials (= code + all the tutorials)
1598    o ecco, option to compute cost for total ssh (mean+anom)
1599    o consistent with addition of ptracer and ssh in pkg/profiles
1600    o profiles: adding ptracer and ssh
1601    o testreport: change multi-test output-file name
1602      (from output.txt.{name} to output.{name}.txt)
1603    o profiles: now ok for mutli-tiles case
1604    o seaice: add 4 parameters for different advection schemes for area,
1605      (effective) seaice thickness, enthalphy, and snow height. Their default
1606      is the standard parameter SEAICEadvScheme
1607    o calc_gw:
1608     - add cosFacU in zonal viscous flux (harmonic.visc.).
1609     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1610       of tutorial_plume_on_slope.
1611    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1612    o calc_gw: true flux-form, account for horizontal grid spacing.
1613      update rotating_tank results, but not plume_on_slope (affected at
1614      truncation level, 11 digits).
1615    
1616    checkpoint58l_post
1617    o calc_gw:
1618     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1619     - remove side-drag for now (need to fix it); update plume_on_slope results.
1620     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1621    o commit code to make SST/SSS weights spatially variable
1622      (based on either variable in-situ or variable initial T/S weights)
1623    o pkg/ecco:
1624      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1625        now based on horizontally varying weights wthetaLev, wsaltLev
1626      * cost_averagesflags now returns year indices in addition to day, month
1627      * sflux balance is performed on annual basis
1628        (sflxumm, sfluxmm2, bal_sfluxmm)
1629      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1630        including separate counting and multipliers
1631    o pkg/rbcs
1632      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1633    
1634    checkpoint58k_post
1635    o testreport:
1636     - always build in dir. "build" (if not there, mkdir build instead of building
1637       & running in input)
1638     - run in dir run (if it exists), in build otherwise.
1639     - call prepare_run (if input/prepare_run exists)
1640     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1641    o pkg/exf modifications to interpolation and rotation routines for more
1642       reasonable treatment of North Pole singularity: for tracers North Pole
1643       value is set to northernmost zonal-mean value, for zonal velocity it is
1644       set to zero, and for meridional velocity it is set to northernmost value.
1645    o pkg/exf/exf_check_range.F
1646     - add tile index to diagnostics and move stop statement to the very
1647       end of the routine.
1648    o pkg/diagnostics: (diagnostics_main_init.F)
1649      define title of isomorphic variables according to the current config.
1650    o pkg/thsice with pkg/seaice dynamics:
1651    - fix domain of computation (interior only, required for exf) and do exchanges
1652    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1653    o towards a standard way of dealing with multi-threading in MONITOR
1654      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1655    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1656       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1657    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1658    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1659    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1660       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1661    o tracer advection:
1662     - clean-up and simplify calc_common_factors.F
1663     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1664       advection subroutine (but still not used within DST advection S/R)
1665    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1666    
1667    checkpoint58j_post
1668    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1669      from file (collects calls previously in FORWARD_STEP)
1670    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1671    o adjoint store dir. adjusted accordingly
1672    o genmake2
1673      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1674    
1675    checkpoint58i_post
1676    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1677      on wind stress (SEAICEstressFactor defaults to 1.)
1678    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1679      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1680    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1681      on CS-grid: no longer loosing mass.
1682    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1683    o pkg/ggl90: fix sloppy output and fix a bug
1684    o pkg/seaice: added SEAICEuseEVPpickup parameter
1685      - Set to false in order to start EVP solver with
1686        non-EVP pickup files when using SEAICEuseEVP
1687      - fix sign error in diffusion in seaice_calc_rhs

1700    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1701       used for mean seasonal cycle, mean diurnal cycle); add an example
1702       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
