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