4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
8      To avoid mixing type (RS/RL) of input/output array argument,
9      replace single mixed-type array with a pair from each type (RS/RL).
10    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
11      is now implemented for all pkgs (previously only done for the main pickup)
12    
13    checkpoint61u
14    o pkg/obcs:
15      - change OB?eta from _RS to _RL and put them into a separate commen block
16      - add code to read OB?eta from a file via obcs_prescribe_read: the code
17        compiles and does not destroy any other experiments, the data is read
18        properly, but the code is not tested in actual applications
19    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
20      create a meaningful unit attribute for the time coordinate variable
21    o pkg/ebm: add plenty of missing "_d 0" ;
22       update results of experiment global_ocean_ebm (fwd + adjoint tests)
23      Notes: several pieces of code only works for (very) specific set up
24       (domain size, lat range, etc ...); should be documented & stop if one
25       of those assumptions is not meet.
26    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
27       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
28          and offline_exf_seaice (seaicetd + adjoint).
29    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
30       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
31        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
32    o few changes to pass when compiling with strick checking of arguments
33       across S/R (allow to find few bugs in S/R calls).
34    o pkg/seaice:
35     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
36       2d-fields, for slightly better performance
37    
38    checkpoint61t
39    o pkg/seaice:
40     - remove unused variables in seaice_evp
41     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
42    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
43       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
44       each processor opens a different file (a fix from Matt).
45    o cg2d:
46       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
47       this reduces number of EXCH calls by 2 when using exch2.
48       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
49       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
50    o pkg/thsice:
51       add code for Near Infra-Red albedo (from Jeff)
52       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
53    o ini_model_io:
54       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
55       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
56       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
57    
58    checkpoint61s
59    o pkg/exch2 (exch2_rxN_cube*):
60       remove last BARRIER (no need to synchronise after getting data from shared
61       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
62    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
63      and generate new output (for the 2 tests) using default rotationPeriod.
64    o pkg/exch2:
65      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
66        (was already the case with AUTODIFF_EXCH2 defined)
67      - add bj in exch2 arrays and S/R.
68      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
69        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
70    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
71      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
72        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
73      - verification experiment natl_box.longstep
74    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
75      allow different versions of ifort (8 or 9) and different versions
76       of mpi (mpich or mpich2) to be used with the same optfile.
77      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
78       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
79    o pkg/seaice:
80      fix previous modif (3-level field removed) for old-pickup reading
81    
82    checkpoint61r
83    o pkg/seaice:
84     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
85      1. introduce fields for time step (N-1)
86      2. do not use levels 2 and 3 anymore (but keep them)
87      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
88         includes changes to pkg/thsice/thsice_get_velocity.F,
89         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
90         pkg/obcs/obcs_apply_uvice.F.
91     - completely remove code for leap-frog time stepping for second order
92       advection
93     - adjusted adjoint accordingly;
94       gradient checks have improved by an order of magnitude!
95    
96    checkpoint61q
97    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
98     - the boundary conditions along open boundaries are unclear, because the
99       associated masks are set to zero and are thus treated as closed when
100       applying the slip-boundary conditions.
101     - move initialisation of grid variables from seaice_init_varia to _fixed
102    o adding doc/diags_changes.txt
103    o model/src:
104      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
105       to avoid "_diags" naming if no relation to pkg/diagnostics.
106      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
107       file and only call PLOT_FIELD_XYZ if debugMode=T.
108      remove few PLOT_FIELD_XY calls outside initialisation.
109      remove few unnecessary BARRIER.
110    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
111      of salt_plume package in Southern Ocean
112    o pkg/thsice:
113     - fix hOceMxL in overlap (needed for sea-ice advection);
114       update output of experiment global_ocean.cs32x15.icedyn.
115    o pkg/seaice:
116     - make the (placeholder-)tracer IceAge a little more meaningful
117      by avoiding ridging of age due to convergent ice flow
118     - add diagnostics for surface temperature, atmospheric and oceanic
119       heat flux, and atmospheric and oceanic ice growth
120    
121    checkpoint61p
122    o eesupp (global_max & global_sum):
123     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
124     - remove starting & endding barrier (no longer needed)
125    o pkg/mdsio, writelocal:
126       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
127       (remove the STOP): uses shared buffer IO to store data from all threads
128       and then let master-thread write nThreads tiles.
129    o pkg/mdsio (read/write field):
130     - tiled IO done in 1 piece (all levels at a time);
131     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
132     - multi-threaded: allow to read/write local (non-shared) array
133       (was already working with singleCpuIO ; now works also without);
134       => no longer needs barrier call after reading a file (added inside
135       mds_read/write field).
136     - move barrier calls outside gather/scatter_2d to mds_read/write_field
137    o pkg/obcs/exf
138      - exf_getffieldrec.F: add a few ". _d 0" and
139                            add code to catch the case fldperiod = 0.  
140      - obcs_precribe_read.F: change if statements so that they match
141                              the variable type (_RL)
142      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
143        exf_iprec) as part of namelist EXF_NML_01
144    o pkg/mdsio:
145      - read/write tiled (local) files: read/write 1-level tile chunk at a time
146        (instead of segment of length sNx); expected to speed up tiled IO.
147    o pkg/exch2:
148      - take buffer copy from/to array out of S/R exch2_send/recv into new
149        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
150        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
151      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
152      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
153        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
154        including Topology header file (and common blocks).
155      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
156        remove 2nd exch call in exch2_s3d_rx (no longer needed).
157      - document S/R arg. list (+ update some comments)
158    o pkg/seaice:
159      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
160        temperature and humidity over sea ice based on climatological values.
161      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
162        of LSR (this change is expected to change the results slightly because now
163        it uses slightly difference moduli from the second last LSR solution, but
164        that is more consistent with the stress computations; this part of the code
165        is not tested in the verification experiments)
166      - fix diagnostics for flux of ice in case of B-grid
167      - turn strain rates eij and press into global fields within global
168        common block in SEAICE.h for more straighforward diagnostics
169      - fix diagnostics for principal stress components, press, zeta, eta
170        to give something meaning full
171    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
172      new output (all 4 tests) using default rotationPeriod.
173    o pkg KPP:
174      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
175      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
176        and normal grid from 1 to Nr)
177    o Fix computations of L4rdt in mom_calc_visc.F
178    o eesupp:
179      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
180      should be called before a "stop" if we know that all process are going
181      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
182    
183    checkpoint61o
184    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
185    o model/src/ini_curvilinear_grid.F:
186       compute angleSin/CosC when they are not read from a file
187    o pkg/seaice:
188       add pseudo time stepping for LSOR
189    o pkg/exch2:
190       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
191    o pkg/seaice:
192       Adding separate sea ice albedo, drag coefficients, and HO in Southern
193       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
194    o SingleCpuIO:
195       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
196    o pkg/seaice:
197       put exchanged variable in (local) common block for MPI+Multi-Threads
198       to work (necessary with exch1, and for now with exch2 too).
199    o verification: to get more experiments tested with mpi, mth and mpi+mth,
200      change tiling of:
201       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
202       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
203      update output of exp:
204       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
205       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
206      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
207                       (note: output.txt generated on faulks using only 1 tile)
208    o eesupp & mdsio (SingleCpuIO):
209     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
210       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
211       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
212     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
213     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
214       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
215    o pkg/exch2:
216     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
217       read parameter file "data.exch2" if it exists; otherwise try default regular
218       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
219     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
220       with new code (not to be used, just as a backup solution).
221     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
222       in utils/exch2/input.
223    
224    checkpoint61n
225    o eesupp & mdsio (SingleCpuIO):
226      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
227        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
228        receive real*4 array (instead of real*8) to read/write 32.bit files.
229        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
230         and remove new mapping S/R)
231    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
232      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
233        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
234        when using exch2. Add S/R to map global io-buffer to global model array.
235      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
236    
237    checkpoint61m
238    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
239      and add 3 other S/R for other types (R4,R8,RS).
240      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
241    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
242     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
243     - reduce number of macro definitions (keep only those which are used);
244       can always call directly the corrresponding S/R if needed.
245     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
246       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
247     Fixed wrong type of arg in:
248       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
249       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
250     To fix: global_sum of var in common block is wrong (multi-threaded) in:
251       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
252     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
253    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
254      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
255    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
256    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
257      edges are closed (zero depth); might happen with "blank tiles";
258      for now, disabled if using OBCS.
259    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
260      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
261    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
262      to reduce length of 1.D array print in STDOUT.
263    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
264      + use 48 tiles (16x8): this will allow to test "blank tiles".
265    o start to test MPI + multi-threaded (change testreport to skip tests
266      where number of tiles do not match).
267    o genmake2: add option "-omp" to turn on Open-MP ;
268      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
269    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
270      and keep the original tile numbering. Note: compatible with old
271      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
272    
273    checkpoint61l
274    o Overlaps had been forgotten in calculating ijk keys : fixed
275    o fix cyrus makedepend for gcc 4.4
276    o experiment fizhi-cs-aqualev20:
277      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
278      and generate new output. Note: new output is much closer to the old
279      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
280      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
281    o pkg/fizhi:
282     - change to avoid indices going deliberately over array-bounds
283     - remove unnecessary MPI stuff
284     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
285     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
286       does not go over array-bounds and therefore returns reliable output.
287     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
288       this S/R has 4 output arguments, which are used inside "get_alarm";
289       when it is called with the same variable "ndum" in place of several
290       output arguments, this produces weird side effect inside "get_alarm"
291      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
292       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
293       address) and produces error.
294    o tools/gemake2: (March 27-29 2009)
295      with option "-mpi": link *_mpi files from "MODS" dir (this is what
296      testreport does).
297    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
298    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
299       update lab_sea.lsr & lab_sea.salt_plume results
300    o pkg/seaice:
301      Major overhaul of the LSOR solver: change discretization from original
302      finite differences to finite volume. The old routine is still in the
303      file seaice_lsr.F and can be turned on with the CPP-flag
304      SEAICE_OLD_AND_BAD_DISCRETIZATION
305      Along with this change, the discretization of the strain rates is changed.
306      The same flag turns on the old discretization in seaice_calc_strainrates.F
307      All verification experiments with seaice are affected (except for
308      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
309      results by setting the above flag.
310      Further changes involve changes in defaults:
311      - ALLOW_FLOODING is defined and turned on by default
312      - SEAICEadvSnow = .true. is now the default
313      - SEAICEadvSalt = .true. is now the default
314      - SEAICEadvAge  = .true. is now the default
315      - SEAICE_clipVelocities  = .false. is now the default
316                                         (as per J. Zhang's recommendation)
317      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
318        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
319      - seaice_growth: replace computation of UG by a simple copy from wspeed
320    
321    checkpoint61k
322    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
323      seaice_lsr: fixed a few metric terms,
324                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
325                  add more debugging diagnostics
326      seaice_evp: removed superfluous many metric terms of FV discretization
327                  of stress divergence
328                  affects lab_sea, lab_sea.hb87
329      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
330                  of stress divergence for non-evp solver
331                  (this part is not tested anywhere)
332      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
333                  they were effectively only half slip
334                  affects lab_sea.hb87
335      updated all relevant verification experiments (except lab_sea//output_adm.txt
336        which was left over, but fails at level 7 & 6)

354      for a rotated grid (rotateGrid=.true.)
355    o pkg/exf: add capability to bypass interpolation for runoff
356      by setting yet another CPP-flag
357    o eesupp/src, B-grid exchange:
358      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
359    o autodiff
360      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
361      allows to switch to single-prec common blocks;
362      corresponding switch occurs in tamc.h, integer isbyte
363      TAF store directivs "byte" and "kind" seem equivalent;
364      Most tamc.h have been updated correspondingly.
365    
366    checkpoint61i
367    o autodiff:
368      fix autodiff_sore/_restore indices for obcs
369      (spotted by I. Hoteit, M. Mazloff)
370    o pkg/autodiff, pkg/ctrl:

380     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
381    o pkg/flt:
382     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
383       init_fixed & ini_varia.
384     - clean-up & simplify linear interpolation S/R:
385       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
386     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
387     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
388     - add vert. coordinate & horiz. indices to output files.
389     - change vertical position in initial condition, from index to depth [m].
390     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
391       (easier to get to a curvilinear grid) ; delX,delY no longer used.
392    o pkg/ggl90: a few modifications:
393     - fix bottom boundary condition, and interpolation of KappaE
394       near top and bottom
395     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
396     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
397     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
398    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
399      (maintain temporary backward compatibility, until next checkpoint)
400    
401    checkpoint61h
402    o pkg/diagnostics with "periodic averaging diagnostics":

411      with ocean biogeo)
412    o pkg/flt:
413     - do some cleaning and fix the restart ;
414     - add output.txt in flt_example/results to get this pkg tested.
415    o genmake2: add an EXTENDED_SRC option and flag.
416       for now, cannot be turned on on command line (only through genmake_local)
417    o pkg/mdsio: read/write vector:
418     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
419     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
420       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
421     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
422      (drop to 4 digits matching for grad). But this test does not look very
423      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
424    
425    checkpoint61g
426    o pkg/flt:
427      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
428       + make OPTIONS file more standard.
429      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
430      - fix _BYTESWAPIO CPP-Flag
431      - standard reading of file-parameter "data.flt"
432      - fix argument list of S/R FLT_RESTART
433      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
434    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
435    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
436      a still unfixed compiler/optimization bug
437    
438    checkpoint61f
439    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
440      update results of global_ocean.cs32x15.icedyn test.
441    o move getcon.F from model/src to pkg/fizhi.
442    o pkg/exf: add parameter for extrapolation of temp up to the surface
443       and option to prevent negative evap (in bulk_largeyeager04 only).
444    o Prather Advection scheme: fix tracer conservation for divergent flow
445      (e.g., when using NonLin Free-Surface).
446    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
447    o gmredi (Visbeck-variable-K):
448     - add more parameters to Visbeck-variable-K.
449     - use a 5 points average for dSigmaR in Visbeck-K calculation
450       (more "homogenous": same stencil and same weights as in dSigmaH)
451     - update output of ideal_2D_oce experiment.
452    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
453      (#undef REAL4_IS_SLOW)
454     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
455       coordinate variable
456     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
457       (surface forcing fields), removes some of the functionality
458     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
459     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
460       probably not all: copy _RS surface flux fields to RL field before
461       calling DIAGNOSTICS_FILL
462     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
463       real*4 (CALL EXCH_*_RS) versions.
464     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
465       (generate new output).
466    
467    checkpoint61e
468    o gmredi (Visbeck-variable-K):
469      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
470      - change computation of Visbeck-K where Slope > Smax :        
471        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
472        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
473    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
474      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
475    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
476    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
477      does not become too large (to avoid precision problems in implicit-diffusion
478      solver); update ideal_2D_oce output.
479    o pkg ggl90:
480      - in ggl90_cal.F: compute only one set of visc/diff, used to
481        step forward TKE/T/S/momentum
482      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
483        have Prandlt =1)
484    o gmredi (fm07):
485      - add lower limit on Transition layer thickness + lower limit on 1/lambda
486      - allow to set few more params from data.gmredi
487    o pkg ggl90:
488          - add missing sqrt(2) factor in computation of mixing length
489            scale in ggl90_calc.F
490            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
491    
492    checkpoint61d
493    o adjoint modifs
494      - adapt to new field rhoInSitu
495      - allow to revert from StoreDynVars2D, StoreDynVars3D
496        to individual fields
497        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
498    o store 3-D (in-situ) density in commom block (DYNVARS.h)
499     - save 1 rho computation.
500     - no longer modify T & S inland when using down_slope pkg.
501    o gad_som : allow to switch to SOM advection for T & S without corresponding
502      pickup files (using new S/R: MDS_CHECK4FILE).
503    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
504      (for useSingleCpuIO to work in multi-threaded)
505    o pkg/shelfice:
506     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
507       with SHELFICEtopoFile in data.shelfice
508     - move code for reading ice shelf topography and modifying hFacC into separate
509       subroutines of the shelfice package
510     - separate initialisation of "fixed" and "variable" variables
511     - kTopC is not (yet) replaced by kSurfC, although this is possible
512    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
513    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
514      and rename:
515      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
516      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
517    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
518    
519    checkpoint61c
520    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
521      to add mass source/sink of fluid in the interior (3-D generalisation
522      of oceanic real-fresh water flux).
523    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
524    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
525    o new pkg: down_slope
526      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
527      - presently, modify T & S inland (dwnslp_calc_rho.F).
528        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
529      - implementation for ocean in P-coords not tested.
530      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
531    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
532      (to facilitate conversion of oceanic pkg to p-coordinate).
533    o change FIND_RHO to FIND_RHO_2D :
534      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
535    o new pkg: cheapaml
536    
537    checkpoint61b
538    o exch2:
539      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
540      - no longer depend on the order sequence (N,S,E,W).
541      - 3rd exchange no longer needed (tested with 24 tiles).
542      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
543      - exch_UV_A-grid readily available (but not yet tested).
544      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
545      (both are no longer needed) in exch_uv: no effect in forward run; but
546       get truncation error differences with adjoint exch.
547    o exch2:
548     - change index-bounds storage (moved from target to local tile,
549       more intuitive this way) ; rename/remove some variables.
550     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
551    
552    checkpoint61a
553    o exch2/matlab-topology-generator:
554      fix bug in index bounds for N-S internal exchange (hard to tell if this
555      had any effect on the solution).
556    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
557      is exceeded
558    o testreport: modify syntax of awk, so that it works also with
559      awk, and not only with nawk and gawk
560    
561    checkpoint61
562    o autodiff
563      Change default for TAF usage by removing argument '-nonew_arg'
564      This changes TAF subroutine argument list (ordering of active var.)
565      Omission of this flag leads to incompatibility w.r.t. TAMC
566      To restore TAMC-compatibility, need following modifs:
567      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
568      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
569      Tested TAF version is 1.9.22
570      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
571    
572    checkpoint60
573    --->>> This is the last checkpoint for which generating the adjoint
574    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
575    --->>> by default.
576    --->>> Future checkpoints will ommit this flag by default.
577    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
578    o pkg/grdchk: Add gradient check to etan0 perturbations.
579    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
580    o pkg/autodiff: more flexibility in zeroadj.
581      model/src: modifying do_oceanic_phys.F accordingly.
582    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
583    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
584      special setup of gmredi for which the adjoint is stable
585      enough for parameter optimization.
586    o bridging the gap between eddy stress and GM.
587      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
588          along with a change in CPP option (now ALLOW_EDDYPSI).
589      -> when using GM w/ GM_AdvForm:
590          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
591          is applied either in the tracer Eq. or in momentum Eq.
592          depending on data.gmredi (intro. GM_InMomAsStress).
593      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
594      The key modifications are in model/src/taueddy_external_forcing.F
595      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
596    
597    checkpoint59r
598    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
599      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
600      fix option to read coriolis(@ cell-corner) from files with CS-grid.
601    o pkg/mnc: add some attributes to standard 1D-coordinate variables
602    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
603      mass points, when using mnc for output
604      - add runtime parameter (missing_value, missing_value_int) to override
605        default (which is the value of getcon('UNDEF'))
606    o pkg/mnc: prepare mnc for the actual use of missing values with the
607      diagnostics package: small fix in mnc_cw_readwrite.template and more
608      initialisation of never used fields
609      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
610      versions
611    o pkg/thsice/thsice_ini_vars.F added default initial values so that
612      thermodynamics sea ice solver does not blow up when some initial fields
613      are missing.
614    o move from external_forcing_surf.F to ini_forcing.F
615      the p-coord. hack consisting in using pLoad to set phi0surf ;
616      update output of tutorial_global_oce_in_p (affected @ truncation level).
617    o Freshen up a bit hs94.1x64x5, notably:
618      remove rotationPeriod and tRef=5*0. (adjoint only), and add
619      exactConserv=.TRUE.
620    o pkg/generic_advdiff:
621      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
622      applies to files where Temperature & Salinity 2nd Order moments are used.
623    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
624      this uses a dynamically allocated internal state data structure
625      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
626      and requires a fortran 90 compiler
627    
628    checkpoint59q
629    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
630       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
631    o Refresh tutorial_global_oce_biogeo, notably:
632      - change bathymetry (put back seamounts in ACC, use hFacs)
633      - change EOS (POLY3 --> JMD95Z)
634      - use Bryan-Lewis vertical diffusivity
635      - use multidimensional advection
636      - remove old virtual virtual in dic pkg, now done through ptracer pkg
637      - change a couple of parameters in dic pkg
638    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
639    o pkg/obcs: change default to OBCSfixTopo = .true.,
640      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
641      - replace "debugMode" with "debugLevel .GE. debLevB"
642    o implementation of TAF directives for gchem,cfc,dic
