4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o adding doc/diags_changes.txt
8  o moved ptracer ctrl index 17 -> 32  o model/src:
9      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
10       to avoid "_diags" naming if no relation to pkg/diagnostics.
11      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
12       file and only call PLOT_FIELD_XYZ if debugMode=T.
13      remove few PLOT_FIELD_XY calls outside initialisation.
14      remove few unnecessary BARRIER.
15    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
16      of salt_plume package in Southern Ocean
17    o pkg/thsice:
18     - fix hOceMxL in overlap (needed for sea-ice advection);
19       update output of experiment global_ocean.cs32x15.icedyn.
20    o pkg/seaice:
21     - make the (placeholder-)tracer IceAge a little more meaningful
22      by avoiding ridging of age due to convergent ice flow
23     - add diagnostics for surface temperature, atmospheric and oceanic
24       heat flux, and atmospheric and oceanic ice growth
25    
26    checkpoint61p
27    o eesupp (global_max & global_sum):
28     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
29     - remove starting & endding barrier (no longer needed)
30    o pkg/mdsio, writelocal:
31       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
32       (remove the STOP): uses shared buffer IO to store data from all threads
33       and then let master-thread write nThreads tiles.
34    o pkg/mdsio (read/write field):
35     - tiled IO done in 1 piece (all levels at a time);
36     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
37     - multi-threaded: allow to read/write local (non-shared) array
38       (was already working with singleCpuIO ; now works also without);
39       => no longer needs barrier call after reading a file (added inside
40       mds_read/write field).
41     - move barrier calls outside gather/scatter_2d to mds_read/write_field
42    o pkg/obcs/exf
43      - exf_getffieldrec.F: add a few ". _d 0" and
44                            add code to catch the case fldperiod = 0.  
45      - obcs_precribe_read.F: change if statements so that they match
46                              the variable type (_RL)
47      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
48        exf_iprec) as part of namelist EXF_NML_01
49    o pkg/mdsio:
50      - read/write tiled (local) files: read/write 1-level tile chunk at a time
51        (instead of segment of length sNx); expected to speed up tiled IO.
52    o pkg/exch2:
53      - take buffer copy from/to array out of S/R exch2_send/recv into new
54        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
55        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
56      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
57      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
58        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
59        including Topology header file (and common blocks).
60      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
61        remove 2nd exch call in exch2_s3d_rx (no longer needed).
62      - document S/R arg. list (+ update some comments)
63    o pkg/seaice:
64      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
65        temperature and humidity over sea ice based on climatological values.
66      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
67        of LSR (this change is expected to change the results slightly because now
68        it uses slightly difference moduli from the second last LSR solution, but
69        that is more consistent with the stress computations; this part of the code
70        is not tested in the verification experiments)
71      - fix diagnostics for flux of ice in case of B-grid
72      - turn strain rates eij and press into global fields within global
73        common block in SEAICE.h for more straighforward diagnostics
74      - fix diagnostics for principal stress components, press, zeta, eta
75        to give something meaning full
76    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
77      new output (all 4 tests) using default rotationPeriod.
78    o pkg KPP:
79      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
80      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
81        and normal grid from 1 to Nr)
82    o Fix computations of L4rdt in mom_calc_visc.F
83    o eesupp:
84      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
85      should be called before a "stop" if we know that all process are going
86      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
87    
88    checkpoint61o
89    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
90    o model/src/ini_curvilinear_grid.F:
91       compute angleSin/CosC when they are not read from a file
92    o pkg/seaice:
93       add pseudo time stepping for LSOR
94    o pkg/exch2:
95       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
96    o pkg/seaice:
97       Adding separate sea ice albedo, drag coefficients, and HO in Southern
98       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
99    o SingleCpuIO:
100       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
101    o pkg/seaice:
102       put exchanged variable in (local) common block for MPI+Multi-Threads
103       to work (necessary with exch1, and for now with exch2 too).
104    o verification: to get more experiments tested with mpi, mth and mpi+mth,
105      change tiling of:
106       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
107       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
108      update output of exp:
109       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
110       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
111      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
112                       (note: output.txt generated on faulks using only 1 tile)
113    o eesupp & mdsio (SingleCpuIO):
114     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
115       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
116       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
117     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
118     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
119       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
120    o pkg/exch2:
121     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
122       read parameter file "data.exch2" if it exists; otherwise try default regular
123       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
124     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
125       with new code (not to be used, just as a backup solution).
126     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
127       in utils/exch2/input.
128    
129    checkpoint61n
130    o eesupp & mdsio (SingleCpuIO):
131      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
132        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
133        receive real*4 array (instead of real*8) to read/write 32.bit files.
134        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
135         and remove new mapping S/R)
136    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
137      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
138        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
139        when using exch2. Add S/R to map global io-buffer to global model array.
140      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
141    
142    checkpoint61m
143    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
144      and add 3 other S/R for other types (R4,R8,RS).
145      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
146    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
147     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
148     - reduce number of macro definitions (keep only those which are used);
149       can always call directly the corrresponding S/R if needed.
150     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
151       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
152     Fixed wrong type of arg in:
153       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
154       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
155     To fix: global_sum of var in common block is wrong (multi-threaded) in:
156       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
157     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
158    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
159      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
160    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
161    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
162      edges are closed (zero depth); might happen with "blank tiles";
163      for now, disabled if using OBCS.
164    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
165      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
166    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
167      to reduce length of 1.D array print in STDOUT.
168    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
169      + use 48 tiles (16x8): this will allow to test "blank tiles".
170    o start to test MPI + multi-threaded (change testreport to skip tests
171      where number of tiles do not match).
172    o genmake2: add option "-omp" to turn on Open-MP ;
173      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
174    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
175      and keep the original tile numbering. Note: compatible with old
176      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
177    
178    checkpoint61l
179    o Overlaps had been forgotten in calculating ijk keys : fixed
180    o fix cyrus makedepend for gcc 4.4
181    o experiment fizhi-cs-aqualev20:
182      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
183      and generate new output. Note: new output is much closer to the old
184      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
185      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
186    o pkg/fizhi:
187     - change to avoid indices going deliberately over array-bounds
188     - remove unnecessary MPI stuff
189     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
190     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
191       does not go over array-bounds and therefore returns reliable output.
192     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
193       this S/R has 4 output arguments, which are used inside "get_alarm";
194       when it is called with the same variable "ndum" in place of several
195       output arguments, this produces weird side effect inside "get_alarm"
196      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
197       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
198       address) and produces error.
199    o tools/gemake2: (March 27-29 2009)
200      with option "-mpi": link *_mpi files from "MODS" dir (this is what
201      testreport does).
202    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
203    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
204       update lab_sea.lsr & lab_sea.salt_plume results
205    o pkg/seaice:
206      Major overhaul of the LSOR solver: change discretization from original
207      finite differences to finite volume. The old routine is still in the
208      file seaice_lsr.F and can be turned on with the CPP-flag
209      SEAICE_OLD_AND_BAD_DISCRETIZATION
210      Along with this change, the discretization of the strain rates is changed.
211      The same flag turns on the old discretization in seaice_calc_strainrates.F
212      All verification experiments with seaice are affected (except for
213      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
214      results by setting the above flag.
215      Further changes involve changes in defaults:
216      - ALLOW_FLOODING is defined and turned on by default
217      - SEAICEadvSnow = .true. is now the default
218      - SEAICEadvSalt = .true. is now the default
219      - SEAICEadvAge  = .true. is now the default
220      - SEAICE_clipVelocities  = .false. is now the default
221                                         (as per J. Zhang's recommendation)
222      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
223        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
224      - seaice_growth: replace computation of UG by a simple copy from wspeed
225    
226    checkpoint61k
227    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
228      seaice_lsr: fixed a few metric terms,
229                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
230                  add more debugging diagnostics
231      seaice_evp: removed superfluous many metric terms of FV discretization
232                  of stress divergence
233                  affects lab_sea, lab_sea.hb87
234      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
235                  of stress divergence for non-evp solver
236                  (this part is not tested anywhere)
237      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
238                  they were effectively only half slip
239                  affects lab_sea.hb87
240      updated all relevant verification experiments (except lab_sea//output_adm.txt
241        which was left over, but fails at level 7 & 6)
242    
243    checkpoint61j
244    o pkg/seaice: turn a few hard wired parameters into run time parameters
245    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
246      time in seconds as promised by the usints in seaice_monitor and exf_monitor
247    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
248      that are not cubed-sphere grids
249    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
250    o pkg/ctrl:
251      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
252    o non-hydrostatic (calc_gw.F):
253      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
254      update output of exp. global_ocean.cs32x15.viscA4
255    o remove backward compatibility for thetaMin,phiMin
256      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
257    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
258      interpolated wind field not only for curvilineargrid=.true., but also
259      for a rotated grid (rotateGrid=.true.)
260    o pkg/exf: add capability to bypass interpolation for runoff
261      by setting yet another CPP-flag
262    o eesupp/src, B-grid exchange:
263      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
264    o autodiff
265      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
266      allows to switch to single-prec common blocks;
267      corresponding switch occurs in tamc.h, integer isbyte
268      TAF store directivs "byte" and "kind" seem equivalent;
269      Most tamc.h have been updated correspondingly.
270    
271    checkpoint61i
272    o autodiff:
273      fix autodiff_sore/_restore indices for obcs
274      (spotted by I. Hoteit, M. Mazloff)
275    o pkg/autodiff, pkg/ctrl:
276      Add flag to reduce all tapelev I/O to single-prec.
277      In data.ctrl set
278        doSinglePrecTapelev = .TRUE.
279    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
280      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
281    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
282      real fresh water flux (not yet)
283    o pkg/mdsio & rw:
284     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
285     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
286    o pkg/flt:
287     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
288       init_fixed & ini_varia.
289     - clean-up & simplify linear interpolation S/R:
290       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
291     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
292     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
293     - add vert. coordinate & horiz. indices to output files.
294     - change vertical position in initial condition, from index to depth [m].
295     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
296       (easier to get to a curvilinear grid) ; delX,delY no longer used.
297    o pkg/ggl90: a few modifications:
298     - fix bottom boundary condition, and interpolation of KappaE
299       near top and bottom
300     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
301     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
302     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
303    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
304      (maintain temporary backward compatibility, until next checkpoint)
305    
306    checkpoint61h
307    o pkg/diagnostics with "periodic averaging diagnostics":
308      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
309    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
310    o pkg/obcs: fix loop ranges for balancing code
311    o pkg/flt:
312     - improve criteria for finding which tile owns a float.
313     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
314    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
315      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
316      with ocean biogeo)
317    o pkg/flt:
318     - do some cleaning and fix the restart ;
319     - add output.txt in flt_example/results to get this pkg tested.
320    o genmake2: add an EXTENDED_SRC option and flag.
321       for now, cannot be turned on on command line (only through genmake_local)
322    o pkg/mdsio: read/write vector:
323     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
324     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
325       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
326     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
327      (drop to 4 digits matching for grad). But this test does not look very
328      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
329    
330    checkpoint61g
331    o pkg/flt:
332      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
333       + make OPTIONS file more standard.
334      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
335      - fix _BYTESWAPIO CPP-Flag
336      - standard reading of file-parameter "data.flt"
337      - fix argument list of S/R FLT_RESTART
338      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
339    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
340    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
341      a still unfixed compiler/optimization bug
342    
343    checkpoint61f
344    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
345      update results of global_ocean.cs32x15.icedyn test.
346    o move getcon.F from model/src to pkg/fizhi.
347    o pkg/exf: add parameter for extrapolation of temp up to the surface
348       and option to prevent negative evap (in bulk_largeyeager04 only).
349    o Prather Advection scheme: fix tracer conservation for divergent flow
350      (e.g., when using NonLin Free-Surface).
351    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
352    o gmredi (Visbeck-variable-K):
353     - add more parameters to Visbeck-variable-K.
354     - use a 5 points average for dSigmaR in Visbeck-K calculation
355       (more "homogenous": same stencil and same weights as in dSigmaH)
356     - update output of ideal_2D_oce experiment.
357    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
358      (#undef REAL4_IS_SLOW)
359     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
360       coordinate variable
361     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
362       (surface forcing fields), removes some of the functionality
363     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
364     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
365       probably not all: copy _RS surface flux fields to RL field before
366       calling DIAGNOSTICS_FILL
367     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
368       real*4 (CALL EXCH_*_RS) versions.
369     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
370       (generate new output).
371    
372    checkpoint61e
373    o gmredi (Visbeck-variable-K):
374      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
375      - change computation of Visbeck-K where Slope > Smax :        
376        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
377        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
378    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
379      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
380    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
381    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
382      does not become too large (to avoid precision problems in implicit-diffusion
383      solver); update ideal_2D_oce output.
384    o pkg ggl90:
385      - in ggl90_cal.F: compute only one set of visc/diff, used to
386        step forward TKE/T/S/momentum
387      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
388        have Prandlt =1)
389    o gmredi (fm07):
390      - add lower limit on Transition layer thickness + lower limit on 1/lambda
391      - allow to set few more params from data.gmredi
392    o pkg ggl90:
393          - add missing sqrt(2) factor in computation of mixing length
394            scale in ggl90_calc.F
395            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
396    
397    checkpoint61d
398    o adjoint modifs
399      - adapt to new field rhoInSitu
400      - allow to revert from StoreDynVars2D, StoreDynVars3D
401        to individual fields
402        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
403    o store 3-D (in-situ) density in commom block (DYNVARS.h)
404     - save 1 rho computation.
405     - no longer modify T & S inland when using down_slope pkg.
406    o gad_som : allow to switch to SOM advection for T & S without corresponding
407      pickup files (using new S/R: MDS_CHECK4FILE).
408    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
409      (for useSingleCpuIO to work in multi-threaded)
410    o pkg/shelfice:
411     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
412       with SHELFICEtopoFile in data.shelfice
413     - move code for reading ice shelf topography and modifying hFacC into separate
414       subroutines of the shelfice package
415     - separate initialisation of "fixed" and "variable" variables
416     - kTopC is not (yet) replaced by kSurfC, although this is possible
417    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
418    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
419      and rename:
420      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
421      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
422    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
423    
424    checkpoint61c
425    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
426      to add mass source/sink of fluid in the interior (3-D generalisation
427      of oceanic real-fresh water flux).
428    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
429    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
430    o new pkg: down_slope
431      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
432      - presently, modify T & S inland (dwnslp_calc_rho.F).
433        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
434      - implementation for ocean in P-coords not tested.
435      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
436    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
437      (to facilitate conversion of oceanic pkg to p-coordinate).
438    o change FIND_RHO to FIND_RHO_2D :
439      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
440    o new pkg: cheapaml
441    
442    checkpoint61b
443    o exch2:
444      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
445      - no longer depend on the order sequence (N,S,E,W).
446      - 3rd exchange no longer needed (tested with 24 tiles).
447      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
448      - exch_UV_A-grid readily available (but not yet tested).
449      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
450      (both are no longer needed) in exch_uv: no effect in forward run; but
451       get truncation error differences with adjoint exch.
452    o exch2:
453     - change index-bounds storage (moved from target to local tile,
454       more intuitive this way) ; rename/remove some variables.
455     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
456    
457    checkpoint61a
458    o exch2/matlab-topology-generator:
459      fix bug in index bounds for N-S internal exchange (hard to tell if this
460      had any effect on the solution).
461    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
462      is exceeded
463    o testreport: modify syntax of awk, so that it works also with
464      awk, and not only with nawk and gawk
465    
466    checkpoint61
467    o autodiff
468      Change default for TAF usage by removing argument '-nonew_arg'
469      This changes TAF subroutine argument list (ordering of active var.)
470      Omission of this flag leads to incompatibility w.r.t. TAMC
471      To restore TAMC-compatibility, need following modifs:
472      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
473      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
474      Tested TAF version is 1.9.22
475      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
476    
477    checkpoint60
478    --->>> This is the last checkpoint for which generating the adjoint
479    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
480    --->>> by default.
481    --->>> Future checkpoints will ommit this flag by default.
482    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
483    o pkg/grdchk: Add gradient check to etan0 perturbations.
484    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
485    o pkg/autodiff: more flexibility in zeroadj.
486      model/src: modifying do_oceanic_phys.F accordingly.
487    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
488    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
489      special setup of gmredi for which the adjoint is stable
490      enough for parameter optimization.
491    o bridging the gap between eddy stress and GM.
492      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
493          along with a change in CPP option (now ALLOW_EDDYPSI).
494      -> when using GM w/ GM_AdvForm:
495          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
496          is applied either in the tracer Eq. or in momentum Eq.
497          depending on data.gmredi (intro. GM_InMomAsStress).
498      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
499      The key modifications are in model/src/taueddy_external_forcing.F
500      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
501    
502    checkpoint59r
503    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
504      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
505      fix option to read coriolis(@ cell-corner) from files with CS-grid.
506    o pkg/mnc: add some attributes to standard 1D-coordinate variables
507    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
508      mass points, when using mnc for output
509      - add runtime parameter (missing_value, missing_value_int) to override
510        default (which is the value of getcon('UNDEF'))
511    o pkg/mnc: prepare mnc for the actual use of missing values with the
512      diagnostics package: small fix in mnc_cw_readwrite.template and more
513      initialisation of never used fields
514      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
515      versions
516    o pkg/thsice/thsice_ini_vars.F added default initial values so that
517      thermodynamics sea ice solver does not blow up when some initial fields
518      are missing.
519    o move from external_forcing_surf.F to ini_forcing.F
520      the p-coord. hack consisting in using pLoad to set phi0surf ;
521      update output of tutorial_global_oce_in_p (affected @ truncation level).
522    o Freshen up a bit hs94.1x64x5, notably:
523      remove rotationPeriod and tRef=5*0. (adjoint only), and add
524      exactConserv=.TRUE.
525    o pkg/generic_advdiff:
526      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
527      applies to files where Temperature & Salinity 2nd Order moments are used.
528    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
529      this uses a dynamically allocated internal state data structure
530      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
531      and requires a fortran 90 compiler
532    
533    checkpoint59q
534    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
535       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
536    o Refresh tutorial_global_oce_biogeo, notably:
537      - change bathymetry (put back seamounts in ACC, use hFacs)
538      - change EOS (POLY3 --> JMD95Z)
539      - use Bryan-Lewis vertical diffusivity
540      - use multidimensional advection
541      - remove old virtual virtual in dic pkg, now done through ptracer pkg
542      - change a couple of parameters in dic pkg
543    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
544    o pkg/obcs: change default to OBCSfixTopo = .true.,
545      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
546      - replace "debugMode" with "debugLevel .GE. debLevB"
547    o implementation of TAF directives for gchem,cfc,dic
548    o remove "exp5" (replaced by tutorial_deep_convection).
549    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
550      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
551      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
552      --> changes results in exp4, seaice_obcs
553    o tutorial_deep_convection :
554      update the set-up and increase resolution and domain size ; start
555      from pseudo initial conditions = output at t=120mn in order to see
556      something happening when running testreport.
557    o pkg/seaice: add os7mp as an advection scheme
558                  add check for advection schemes
559                  add a flag for restoring T and S underneath sea ice
560    o pkg/my82: add netcdf-support and diagnostics
561    o thsice pkg:
562      - Now hsMax limits snow height by turning it into ice following
563        flooding scheme (and now conserving energy)
564      - Slight rewriting of the formula in thsice_calc_thick.F
565      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
566      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
567    
568    checkpoint59p
569    o gchem / dic / cfc :
570      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
571      - add new parameter files: "data.dic" & "data.cfc" ;
572      - various re-arrangement in initialisation & header file ;
573      - fix tutorial_global_oce_biogeo for multi-threaded test.
574    o pkg/dic: test for "pickup_dic" file when restarting ;
575      if no pickup-file, can restart with a re-initialised pH (same as it did
576      before) providing pickupStrictlyMatch is set to False.
577    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
578      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
579    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
580      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
581    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
582     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
583       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
584    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
585       scheme to use for vorticty-term ;
586     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
587       (with default selectVortScheme, return to original discretisation)
588     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
589    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
590    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
591      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
592      also fix diagnostics VISCAHW & VISCA4W.
593    
594    checkpoint59o
595    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
596    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
597      move a few statemens out the main loop into separate loops
598    o pkg/shelfice:
599      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
600        (kg/m^2/s), does not break tests, because in verification/isomip,
601        rhoConstFresh=rhoConst (by accident)
602      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
603      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
604        new file model/src/seawater.F, so that they are available for all pkgs.
605      - convert potential temperature into in-situ temperature. This changes the
606        isomip tests => update tests
607    o add a flag writePickupAtEnd (default=true) to be able to suppress
608      writing a pickup at the last timestep
609    o tools/mpack-1.6 :
610      - disable automake (not working) and autoconf (not needed).
611      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
612        also cleaner with much less compilation warnings.
613    o pkg/profiles:
614      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
615      (for "less than 32 characters name" compiler requirement)
616    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
617      conditions that have a different sampling frequency than S/T/U/V obcs
618    o pkg/diagnostics (stats-diags):
619      - fix global Min/Max in case 1 processor get only empty tiles
620    o genmake2: replace (4 times)
621         make genmake_tc_1.o >> genmake_warnings 2>&1
622      with
623         COMM="$CC $CFLAGS -c genmake_tc_1.c"
624         echo $COMM >> genmake_warnings
625         $COMM >> genmake_warnings 2>&1
626      to make genmake2 always see the value of CC as specified in the optfile.
627    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
628      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
629      - modify verification advect_cs test to test SOM-advection on CS-grid.
630    o pkg/ctrl:
631      - Rewrite of ctrl_map_ini_ecco.F,
632        introducing a generic routine (ctrl_map_ini_gen.F).
633      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
634    
635    checkpoint59n
636    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
637      number in dedicate array "hdiag":
638      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
639        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
640      - many small changes (integer format) for large number of diagnostics
641      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
642        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
643    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
644      usingSphericalGrid, this allows to define the rotated grid coordinates
645      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
646      geographical coordinates according to the inverse of the rotation defined
647      by the Euler angles, so that Coriolis parameter and online-interpolation by
648      exf works with the geographical coordinates on XC/YC/XG/YG.
649      Naturally, this feature does not work with all packages, so some
650      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
651      profiles), because there the coordinates are assumed to be regular
652      spherical grid coordinates.
653    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
654      - introduce isopycnal diffusion coefficient control.
655    o tools/adjoint_options:
656      - additional control vector components.
657    o pkg/mnc: have mnc create marginally meaning full coordinate variables
658      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
659    o pkg/mypackage:
660      - add example of read/write pickup for state-var ;
661      - add entry points to the main code for state-vars diags & write-pickup.
662    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
663      transitions for useExfYearlyFields
664      - add new subroutine that determines the file to read from for
665        use*YearlyFields = .TRUE. and .FALSE.
666      - add a verification experiment to global_with_exf that tests
667        useExfYearlyFields with USE_EXF_INTERPOLATION defined
668    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
669      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
670      subroutines (which could be generated from a template, because they are
671      almost identical), for now they are included in obcs_prescribe_read.F for
672      simplicity
673    o pkg/exf:
674      - add a little more diagnostic to exf_interp_read (in analogy to
675        mds_read_field, can be turned off with debugLevel < debugLevA=1)
676      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
677        ugly but fast by unrolling short inner loops, inserting a unroll=8
678        directive in routine lagran, and splitting a loop and making do while the
679        outermost loop (the latter requires the intoduction of index arrays)
680    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
681    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
682      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
683    o verification/seaice_obcs: updated for restart test and latest options
684    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
685      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
686      for now this is only available for the C-grid code and also within
687      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
688    
689    checkpoint59m
690    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
691      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
692    o gad_som : fix flux output (& diagnostics) to have same units as other  
693      advection scheme fluxes (was previously multiplied by deltaT).  
694    o added verification/seaice_obcs both to test seaice open boundaries
695      and to provide an example matlab scrpt for generating them
696    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
697    o pkg/salt_plume: clean up salt_plume_frac.F to
698      remove redundancy in PlumeMethod 1 and 4
699    o pkg/kpp: added saltplume diagnostics
700    o pkg/obcs and pkg/seaice:
701      - do not set uice and vice to zero when OB*icefile are unspecified
702      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
703      - moved seaice tracer obcs after call to seaice_growth
704    o pkg/salt_plume: added various options for salt plume depth
705      criterion and for vertical distribution of the salt
706    
707    checkpoint59l
708    o pkg/ptracers: new version of ptracers pickup:
709      read meta file and write only fields which are needed to restart.
710      ( same logic as main pickup file ; also using pickupStrictlyMatch )
711    o pkg/seaice:
712      - add timescale for melting due to warm mixed layer as a means of
713        setting SEAICE_availHeatFrac more conveniently
714      - add a CPP-flag/runtime parameter check for flooding algorithm
715      - reformulated availHeat in seaice_growth.F to be independent of AREA
716    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
717      unit changes
718    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
719    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
720      SX vector computer.
721    o pkg/seaice:
722      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
723        seaice forcing fields can now be read only through pkg/exf
724      - removed some unused halos
725    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
726    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
727      or U/VICE from U/VWIND before computing U/VSTRESS
728    
729    checkpoint59k
730    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
731      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
732    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
733      all experiments pass when compile with un-initialised var. checking option.
734    o added pkg/salt_plume
735    o script to test restart (for now, in MITgcm_contrib/jmc_script)
736    o pkg/seaice: new read/write pickup version.
737      read meta file and write only fields which are needed to restart.
738      ( same logic as main pickup file ; also using pickupStrictlyMatch )
739    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
740    o lab_sea.hb87: modify the domain & update output.hb87.txt :
741      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
742      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
743      process. Fixed here by closing the domain at the Northern boundary.
744    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
745    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
746      a set of consecutive levels in/from a 3-D array.
747    o pkg/ptracers:
748      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
749      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
750    
751    checkpoint59j
752    o in pkgs: dic, obcs, offline, rbcs:
753      standard way to compute coeff. for time interpolation between 2 time reccords
754      which retains full precision (& make results less dependent on compiler).
755      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
756    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
757      packages instead of reading ice cover and wind speed separately
758    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
759     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
760      to allow to compile customized code before the update)
761    o cleaning-up:
762      - fix CPP instruction syntax in pkg/obcs
763      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
764        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
765      - fix some threads issue in IO parts.
766    o pkg/dic:
767      - add tons of "_d 0" (--> much better testreports !)
768       and then update outputs of tutorial_global_oce_biogeo
769    o pkg/mom_fluxform:
770      add a special version of momentum advection intended to conserve momentum
771      next to a bathymetry step or a coastline edge. (default = off = #undef)
772    o new read/write pickup version:
773      - for now, only implemented for main (mdsio) pickup file.
774      - write out only what is needed to restart; merge pickup_nh , pickup_ph
775        and main pickup together.
776      - read meta file; read only what is needed to restart; stop if a field
777        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
778        if it make sense (even if the restart is not perfect).
779      - if no meta file, assume that pickup to read corresponds exactly to
780        a pickup that would currently be written.
781      - read pickup written in the old format (until checkpoint59i) if it
782        recognizes an old meta file (no field-list).
783      - add a meta file in exp. which starts from a pickup: 2 cases:
784        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
785         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
786        b) a meta file describing the content of the associated pickup file
787         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
788    o pkg/mdsio & pkg/rw:
789      - new routine to read a meta file ; new set of routine to read
790        Multiple-fields file (with meta file).
791    o added open boundary conditions capability for seaice
792        HSNOW, HSALT, UICE, and VICE
793    
794    checkpoint59i
795    o adjoint:
796      * fix multiDimAdvection adjoint
797        (partial recomputation problem by TAF for fVerT(:,:,kDown)
798        and comlev1 size definition (maxpass vs. max. number of tracers)
799      * verification/global_ocean.90x45x15 adjoint now tests
800        NLFS and multiDimAdvection using DST3 (=30)
801      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
802    o pkg/kpp: add "_d 0" to real constant (if missing);
803      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
804      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
805    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
806      for internal parameters related to restart process (formerly from PARAMS.h)
807      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
808    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
809      as argument. (only atm2d & obcs write_pickup have not yet been updated)
810    o pkg/monitor:
811      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
812      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
813      - account for deep Atmosphere factor and density factor (anelastic)
814    o added open boundary conditions capability for seaice HEFF and AREA
815    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
816      thermodynamics
817      - requires a little reorganization, which affects the testreport results
818        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
819        so that now the conservative form is tested
820      - add a few comments
821    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
822    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
823    o add new diagnostics to seaice: advective, diffusive fluxes (only for
824      multidim-advection, for scheme 2 they are not filled) and transports,
825      thermodynamic growth rates
826    o change units of EmPmR (inside the code, + within coupling interface)
827      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
828      Affects results @ truncation level (cg2d match) and update output of
829       experiments: lab_sea(6), global_ocean.90x40x15(10),
830      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
831      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
832      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
833      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
834    
835    checkpoint59h
836    o pkg/exf:
837      - improve vectorization by moving if-statement out of loops in
838        exf_mapfields, exf_radiation
839      - exf_bulkformulae.F: introduce 2D fields and vectorize code
840    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
841    o testreport:
842      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
843        monitor & update offline_exf_seaice exp. output.
844      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
845    o pkg/seaice:
846      - bug fix in the evp solver: boundary conditions were affected be
847        masking of zMax/zMin (changes results)
848      - minor bug fix in boundary conditions in seaice_calc_strainrates
849        (changes results for no_slip)
850      - seaice_lsr.F: make interpolation of eta dependent on boundaries
851      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
852      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
853        stress formulation and no-slip boundary conditions
854    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
855      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
856    o pkg/seaice: a first HSALT time stepping equation has been checked in
857    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
858      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
859      without requiring DO-IF statements
860    o pkg/thsice:
861      use continuous power-law function for partition of energy between lateral
862      melting/freezing and thinning/thickening ; old code using step function
863      still available with #undef THSICE_FRACEN_POWERLAW
864      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
865    o testreport: change AD testing : check against results/output_adm.txt
866      using same scripts as for forward test.
867    
868    checkpoint59g
869    o adjoint testing: in preparation for changing testreport:
870      - output format: cost and grad written on separated lines
871      - ad output results in directory "results" (instead of "results_ad")
872    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
873    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
874    o pkg/ecco: allow user defined cost function contributions
875    o testreport:
876      Allow to choose (per experiment) the list of tested output variables
877       and the main variable (used to issue a pass/FAIL ) ;
878      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
879      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
880      Also modify printing of summary:
881       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
882       b) echo the list of tested variables in the individual summary.txt of
883          each experiment.
884    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
885      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
886      (but still depend on the tile decompostion of the domain).
887    o pkg/seaice: change a discretization detail to make the B-grid code
888      "more symmetric". This change is likely to remove all "ridges/leads" that
889      where quasi-aligned with the grid in B-grid solutions. It may also be
890      the solution to the stress coupling issues with the B-grid.
891    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
892      remove .cvsignore from input dir. (since testreport no longer run here).
893    o pkg/thsice:
894     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
895     - fix reshaping of sea-ice just after advection:
896       melt all the ice only if ice-volume is too small.
897     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
898       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
899     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
900    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
901      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
902    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
903      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
904      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
905      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
906      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
907      -> update output.txt
908    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
909     this affects truncation error: -> update output.txt of exp:
910      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
911      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
912    
913    checkpoint59f
914    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
915    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
916      a bounded range (in forward mode)
917    o pkg/ecco, ctrl, autodiff and mom_common:
918     internal parameter controls, completements of implementations
919    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
920    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
921      (not seem any difference in testing results).
922    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
923       at face corners.
924    o pkg/generic_advdiff:
925     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
926      loop range indices for computing vertical advection tendency
927      and do the calculation in the interior only (no overlap) ;
928      for now, only implemented for SOM advection (to save CPU time).
929     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
930    o exch2 adjoint
931      First set of changes:
932      - add exch2 hand-written adjoint templates
933      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
934        This will require cleanup in pkg/autodiff/*.F
935        (changed routines currently kept separate in verif. code/)
936      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
937        that used to hide exch2 or cubed-sphere specific code
938        (commented via 'cph-exch2')
939    o pkg/seaice
940      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
941    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
942       output of global_ocean.cs32x15.thsice .
943    
944    checkpoint59e
945    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
946      for B-grid vector (not yet tested) and C-grid vector (<- only used
947      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
948    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
949      (#ifdef ALLOW_SALT_PLUME)
950    o gather_2d/scatter_2d: removed halo regions
951    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
952      scheme and the corresponding test case (under front_relax dir). For now,
953      only available with Skew-flux form and not yet tested in realistic set-up.
954      adjoint: store directives updated, but gradient checks deteriorated,
955      so maybe GM/Redi adjoint is now broken.
956    o seaice adjoint
957      * add AREA, HEFF, HSNOW as control variable
958        (should not change lab_sea results)
959      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
960    o pkg/seaice:
961      * added computation of saltFlux in seaice_growth;
962        For time being, sea ice salinity is assumed constant
963        contribution of snow flooding to freshening of sea ice is neglected.
964        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
965        defaults to 0.0 in order to maintain backward compatibility.
966        Typical values for SEAICE_salinity are 4 to 10 g/kg.
967      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
968      * added SEAICE_availHeatFrac, which specifies fraction of surface level
969        heat content used to melt or grow ice
970      * commented out cap of HICE: it helps keep ice thinner
971      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
972      * applied OBCS T/S mask to HEFFM sea ice mask
973    
974    checkpoint59d
975    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
976     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
977     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
978    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
979     and change default value of parameter "GM_Small_Number";
980     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
981       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
982       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
983    o pkg/ecco: cost function when applying pkg/smooth to controls
984    o pkg/ctrl: add forcingPrecond run time parameter
985    o pkg/seaice:
986     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
987     - fix bug in metric terms of u-equation in LSR solver (implicit part),
988       changes verification/lab_sea
989     - rearrange implicit part of u-equation in LSR solver to make it easier to
990       read, understand, and debug. This causes changes at the truncation level.
991     - fix (serious) bug in the boundary conditions (sign error in the implicit
992       part) of the LSR solver. Changes all LSR results.
993     - fixed problem with HSNOW initialization to avoid thick snow when AREA
994       is initilized with small values - does not change lab_sea results.
995     - added HsnowFile initialization capability
996    o pkg/smooth: addition to model/src and pkg/ctrl so allow
997     initialization of pkg/smooth and application to control vector
998    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
999    o dependencies: pkg/profiles requires pkg/cal
1000    o pkg/profiles:
1001     - added option ALLOW_PROFILES_GENERICGRID
1002         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1003         that interpolation information (grid points and coefficients) is provided
1004         within the netcdf input files.
1005         -> sample matlab scripts can be found in MITgcm_contrib/gael
1006         that allow you to prepare netcdf input files.
1007     - also modified: cleaner include statements, cleaner error print statements,
1008       cleaner stops when error, and more tests of the netcdf input files consistency.
1009    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1010    o pkg/seaice:
1011     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1012       requires a new routine: seaice_diagnostics_fill.F
1013     - make sure that seaice does not move if not forced (pressure replacement
1014       method, Hibler and Ip, 1995), changes results
1015     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1016     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1017       It is turned off by default (=-1.), because it changes the results.
1018     - make it possible to read AREA from a file, too.
1019    
1020    checkpoint59c
1021    o add S/R and diagnostics for oceanic mixed-layer depth
1022    o move GMRedi call after all vertical mixing schemes (including KPP)
1023    o pkg/thsice:
1024     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1025      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1026    o pkg/obcs:
1027     - bug fix for balance code
1028    o pkg/seaice:
1029      - allow values of SEAICE_elasticParm > 1
1030      - add new parameter SEAICE_evpTauRelax as an alternative
1031        to SEAICE_elasticParm
1032      - make lsr boundary conditions free slip (by default), changes result
1033      - add code for no slip boundary conditions for lsr
1034      - set minimum of zeta to zero (and not 4e8) (changes results)
1035      - add a cap on AREA after advecting AREA if seaice_growth is not called
1036    o change calculation of Visbeck K:
1037      - no longer depend on tapering scheme; instead, compute slope (limited
1038        by GM_maxSlope). this is equivalent to what was comuted before with
1039        clipping or linear tappering.
1040      - fix vertical averaging (wrong by 1/2 level)
1041      - leave the old version (but will not be maintained) within
1042        #ifdef OLD_VISBECK_CALC / #endif
1043      - update output of exp. ideal_2D_oce
1044    o change error catch in calc_r_star to improve vectorization
1045    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1046      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1047    o adjoint:
1048      Re-organized adjoint checkpointing according to Matt Mazloff
1049      (but with modifs/completions/cleanups)
1050      Storing is now bundled into large arrays to optimized I/O
1051      (and second step in cleanup of the_main_loop)
1052    
1053    checkpoint59b
1054    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1055      - export/import (between ocean & coupler) fields needed for ocean DIC.
1056    o pkg/seaice:
1057      - get rid of three more exchanges seaice_calc_viscosities (required
1058        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1059      - bug fix in seaice_ocean_stress (update of lab_sea required)
1060      - reduce loop boundaries to necessary minimum also in seaice_evp
1061      - go back to the old way of computing deltaC/Z as the adjoint likes that
1062        better
1063    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1064      passive tracer to an Age Tracer) + update output.txt
1065    o pkg/exf:
1066      - implement A-grid / C-grid selection for wind-stress input files.
1067      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1068      for now, in exf_bulk_largeyeager04.F only :
1069      - change implementation for case where windspeed + 2. components wind-stress
1070        are read-in. AND use rhoConstFresh to convert evap.
1071    o pkg/seaice:
1072      - use correct EXCH_UV for wind-forcing (on A-grid).
1073      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1074        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1075    o pkg/exf:
1076      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1077      EXF_INTERPOLATION:
1078      - merge global_with_exf/code version of exf_interp_read.F
1079        to the main code ;
1080      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1081        reading the file ; Important: This options needs to be defined to recover
1082        previous code.
1083        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1084      - no longer loose real*8 precision along the way when using exf_iprec=64.
1085    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1086      - change discretisation of evp-solver in order to avoid another exchange
1087        (changes lab_sea) and clean up a little
1088      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1089        help the adjoint (this also changes the results slightly)
1090      - add a few "_d 0" where they had been missing in seaice_evp.F
1091      - cleaning up: remove unused seaice_calc_rhs.F
1092    o pkg/exf: some cleaning-up:
1093      - change various "constants" into runtime parameters
1094      - cleaned-up Large&Yeager04 routine which should eventually
1095        replace exf_bulkformulae.F (changed names of S/R and CPP)
1096        and merged various ALLOW_ATM_WIND options
1097     only used with thsice pkg (in thsice_get_exf.F):
1098      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1099        which are used when useStabilityFct_overIce=TRUE (= the default)
1100      - change default values of ice & snow emissivity and scale downward LW
1101        by ice & snow emissivity.
1102    o pkg/thsice:
1103     fix few little problems, in thsice_calc_thickn.F:
1104      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1105      - melt only laterally if hIce < hThinIce (as the comments say)
1106      and in thsice_extend.F:
1107      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1108      - start to form ice as soon as the minimum ice-volume is reachable.
1109     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1110      and cpl_aim+ocn
1111    o pkg/kpp
1112     - move computation of surface related input fields to KPP into a new
1113       subroutine kpp_forcing_surf.F
1114     - remove wrong (within bi,bj loops) EXCH calls.
1115     - little cleaning (add argument myThid in last position, cvs header ...)
1116     - for now, fix conservation problem by exchanging KPPviscAz (may not
1117       be the best fix)
1118    o pkg/seaice
1119     - check for inconsistent evp parameter/cpp-flag combination
1120     - remove leftover errIO flat for obsolete name list error handling
1121    o OpenAD
1122     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1123    
1124    checkpoint59a
1125    o pkg/seaice: some parameter clarifications and a little bit of clean up
1126    o pkg/thsice: rename run-time parameters:
1127       himin       -> hIceMin
1128       himin0      -> hThinIce
1129       hihig       -> hThickIce
1130       i0          -> i0swFrac
1131       transCoef   -> bMeltCoef
1132       frac_energy -> fracMelting
1133      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1134       with default values (for now) that do not change the results.
1135      remove old version of thsice vars advection in pkg/seaice.
1136    o in FFIELDS.h:
1137      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1138      - make pLoad & sIceLoad always available (but still only used if
1139         ATMOSPHERIC_LOADING is #define).
1140    o pkg/kpp: replaced _KPP_RL with _RL
1141    o bug fixes for vertical diffusivity computations when both KPP and
1142        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1143        are no longer updating the vertical diffusivity array
1144        (passed as argument) but are (re-) setting those arrays.
1145    o pkg/seaice: fix bug in evp solver, while doing that
1146      - change (improve?) discretization of stress computations for both
1147        cgrid-lsr and evp solver
1148      - add a new routine to compute strain rates
1149      - the above changes lab_sea results
1150      - add no slip conditions for evp solver (off by default), lsr-version
1151        may follow
1152      - fix exchange for shear at Z-points (does not change lab_sea)
1153      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1154        (to force the user to pick a time step since there is not "safe" way
1155        of choosing it)
1156      - add principal stress diagnostics
1157      - rearrange fields for evp a little to avoid having to call a: too many
1158        exchanges and b: exchanges for stress trensor components which we do
1159        not have.
1160      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1161        of evp, complete rewrite for lsr case (latter is does not yet work
1162        in all cases)
1163    o pkg/kpp: add code to have mixing in shelf ice caverns
1164      - add myThid to all kpp routines (long overdue)
1165    
1166    checkpoint59
1167    o pkg/exf:
1168      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1169        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1170      - move exf header files from lower_case.h to UPPER_CASE.h ;
1171        add missing cvs Header & Name
1172      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1173      - add namelist param. selectStressGridPosition, exf_monFreq
1174      - retire many _CLIM routines, and remove data.exf_clim
1175        + params moved to data.exf
1176        + climsst, climsss now handled by exf_set_gen, i.e.
1177          climss?period=0 refers to constant field,
1178          climss?period=-12 to monthly forcing
1179      - split up namelists in data.exf
1180    o pkg/seaice:
1181      - remove seaice_exch and seaice_exch_uv
1182      - remove superfluous exchange of theta
1183      - add myThid to seaice_budget_ocean/ice
1184      - add new interface for atmospheric wind forcing (C-grid only)
1185        + new routine
1186        + two new field (taux, tauy for stress over ice)
1187        + removed one global field (DAIRN) for C-grid case only
1188    o pkg/thsise
1189      - 2nd set of modifs for thsice adjoint in conjunction with exf
1190    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1191    
1192    checkpoint58y_post
1193    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1194      vertical diffusivity, similar to that in MOM4; turned on using
1195      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1196      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1197    o Added capability for 3D specification of background vertical diffusion
1198      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1199      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1200      "data" file that contains the 3D vertical diffusivity coefficients.
1201    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1202      - add code within pkg thsice to advect & diffuse sea-ice fields
1203      similar to (and will replace) what has been added in  seaice_advdiff.F,
1204      but: - conserving Mass, Heat & Salt.
1205           - better when using non-linear advection scheme (not yet fully tested)
1206           - can also be used in atmospheric set-up (for now, only the diffusion).
1207    
1208    checkpoint58x_post
1209    o IO option for global-file compact format:
1210      - add options when generating topology (utils/exch2/matlab-topology-generator)
1211      - add I/O capability (pkg/mdsio).
1212      - adapt utils/matlab/rdmds.m to read this format.
1213      for now long-line format not yet supported by pkg/mdsio (& exch2).
1214    o shelfice: add a few diagnostics
1215    
1216    checkpoint58w_post
1217    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1218      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1219      (and replace horiVertRatio in NH code).
1220      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1221                         and tutorial_plume_on_slope (sensitive to truncation)
1222    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1223      directly to drive seaice model (C-grid only)
1224    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1225     - reintroduce computation of wind from stress,
1226     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1227       mass points to avoid tau = 0
1228     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1229    o rdmnc.m: make it work with "global" files created with gluemnc
1230    o rdmnc.m : some improvements in dealing with singleton dimension
1231      (tested on all testreport mnc output files).
1232    o genmake2: disable pkg/profiles if netcdf test fails.
1233    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1234    o move call to cal_readparms up to make calendar parameters/variable available
1235      to all packages
1236    
1237    checkpoint58v_post
1238    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1239      useDynP_inEos_Zc tested.
1240    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1241    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1242      and portions thereof.  See read_cs.txt for description and examples.
1243    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1244      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1245      following the great-circle arc between those 2 points.
1246    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1247      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1248    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1249     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1250     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1251     - still needs work (not working with some options ; efficiency to improve)
1252       and serious testing.
1253     - use this scheme for temperature & salinity in 2 advection test exp.:
1254       advect_xy & advect_xz, respectively.
1255    
1256    checkpoint58u_post
1257    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1258    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1259    o testreport: add option "-skipdir" to skip some test.
1260    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1261      momentum calculation.
1262    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1263    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1264      remove checkpoint.F and the_correction_step.F (no longer used);
1265      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1266    o add option (linFSConserveTr) to correct for tracer source/sink due to
1267      Linear Free surface
1268    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1269    o pkg/thsice: fix reading mnc-pickups
1270    
1271    checkpoint58t_post
1272    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1273    o pkg/mdsio:
1274     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1275       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1276       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1277     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1278     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1279       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1280     - new S/R (to replace MDSWRITEMETA), which allows to write more
1281       informations (variable names, time ...) to meta files.
1282     - modify rdmds.m to give back the meta file content.
1283    o pkg/diagnostics: change vertical interpolation to be safer, and more
1284       flexible (define p-levels to interpolate to in data.diagnostics);
1285      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1286       diagnostic pointer.
1287    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1288    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1289    o fix multi-category seaice:
1290     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1291       SEAICE_MULTICATEGORY
1292     - fix short wave heat flux
1293    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1294       and allow to use EVP solver. Change forward lab_sea: test both EVP
1295       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1296    o Initial check-in of lab_sea adjoint
1297      (very similar to natl_box_adjoint/code_seaice)
1298      * used C-grid and EVP solver
1299      * used KPP, GM/Redi
1300      * uses inAdExact=.TRUE.
1301      * gradient checks fail for both ADM and TLM
1302        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1303        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1304        issue is related to forward mismatch between g77 an ifort
1305    o pkg/seaice: overhaul of thermodynamics
1306     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1307     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1308     - move a few global fields out of SEAICE.h into seaice_growth.F and
1309       make them 2D (FICE/QNETO/ ...)
1310     - remove FO (it is the same as QNETO)
1311     - introduce a few local fields to avoid modifying external fields such
1312       as atemp, etc.
1313    
1314    checkpoint58s_post
1315    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1316      changed exf_set_gen.F so that
1317        genperiod=0 means input file is one time-constant field and
1318        genperiod=-12 means input file contains 12 monthly means
1319    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1320      this affects truncation error ; generate new output file for exp. which
1321      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1322        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1323        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1324        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1325        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1326        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1327    o start implementation of deep-atmosphere and anelastic formulation
1328    o verification: remove 2nd copy of input files and use script "prepare_run"
1329      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1330    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1331    o profiles: fix for multithreaded case
1332    
1333    o diagnostics: rename few diags:
1334      s/'PRESSURE'/'RCENTER '/g
1335      s/'TICE    '/'oceFreez'/g
1336      s/'TAUX    '/'oceTAUX '/g
1337      s/'TAUY    '/'oceTAUY '/g
1338      s/'SWFLUX  '/'oceQsw  '/g
1339      s/DIFx/DFxE/g
1340      s/DIFy/DFyE/g
1341      and add few ocean-forcing diagnostics:
1342      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1343    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1344      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1345      as actual snow thickness.  It now refers everywhere to effective snow
1346      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1347    
1348    checkpoint58r_post
1349    o modifications to pkg/seaice/growth.F, which change results of
1350      lab_sea experiment: fixes pertain to melting snow over open water, to
1351      masking EVAP under sea ice, and to using the correct AREA variable for
1352      computations of EVAP, PRECIP, HSNOW, and GHEFF
1353    o add ability to read bathy, salt, and theta using MNC (off by def)
1354    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1355      both are turned off by default and do no change any results
1356    o seaice advection with pkg/thsice: a step toward the use of non-linear
1357      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1358    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1359      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1360      in natl_box (affects results @ truncation level: update output.txt)
1361    o multi-threading and IO:
1362      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1363      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1364        (needed to work with SingleCpuIO): tested in all verif. exp.
1365    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1366      affects the results (but none of the verification test uses this scheme).
1367    o Adding some pkg/diagnostics capability to pkg/seaice
1368      (will certainly be subject to changes)
1369    o ctrl: adding new control variables:
1370      lwflux, lwdown, evap, snowprecip, apressure, runoff
1371    
1372    checkpoint58q_post
1373    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1374      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1375      high_res_cube configuration by 4% on Columbia.
1376    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1377      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1378      dynamical allocation (seems to work in multi-threaded).
1379    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1380      single CPU io) so that TAF does not have to see EESUPPORT.h
1381    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1382    
1383    checkpoint58p_post
1384    o obcs: stop if obcs is used with useCDscheme = .true.
1385    o shelfice:
1386     - fix a sign error so that no slip at shelfice interface works
1387     - remove stop for combination non-hydrostatic code and shelfice. That does
1388       not mean, that the results are correct, but at least they are numerically
1389       stable
1390    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1391    o added adjoint exch routined for all exch*3d* routines
1392      and updated flow directives
1393    
1394    checkpoint58o_post
1395    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1396      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1397    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1398      and clean-up reading/writing of pickup files.
1399    o fix local version of read/write pickup (NH part) in rotating_tank/code
1400    o simplify EXCH interface:
1401     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1402     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1403    o added the regrid package
1404    o shelfice:
1405     - add a simple boundary layer scheme to reduce noise
1406     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1407    
1408    checkpoint58n_post
1409    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1410       local variable (not in common block).
1411    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1412      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1413      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1414        to work with SingleCpuIO.
1415    o add "_d 0" to real constant of pkg/cfc subroutines ;
1416       update exp. cfc_exemple & tutorial_cfc_offline output files.
1417    o multi-threading and IO:
1418      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1419        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1420      - barrier before and after reading.
1421      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1422      - avoid using MDS_WRITELOCAL for LAND pkg output.
1423      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1424        common-block variables ; Allows multi-threading with master-thread IO.
1425    o change default MAX_NO_THREADS from 32 to 4 ;
1426      and stop cleanly when MAX_NO_THREADS is too small.
1427    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1428    
1429    checkpoint58m_post
1430    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1431       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1432    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1433       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1434       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1435    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1436        add MITgcm_tutorials (= code + all the tutorials)
1437    o ecco, option to compute cost for total ssh (mean+anom)
1438    o consistent with addition of ptracer and ssh in pkg/profiles
1439    o profiles: adding ptracer and ssh
1440    o testreport: change multi-test output-file name
1441      (from output.txt.{name} to output.{name}.txt)
1442    o profiles: now ok for mutli-tiles case
1443    o seaice: add 4 parameters for different advection schemes for area,
1444      (effective) seaice thickness, enthalphy, and snow height. Their default
1445      is the standard parameter SEAICEadvScheme
1446    o calc_gw:
1447     - add cosFacU in zonal viscous flux (harmonic.visc.).
1448     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1449       of tutorial_plume_on_slope.
1450    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1451    o calc_gw: true flux-form, account for horizontal grid spacing.
1452      update rotating_tank results, but not plume_on_slope (affected at
1453      truncation level, 11 digits).
1454    
1455    checkpoint58l_post
1456    o calc_gw:
1457     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1458     - remove side-drag for now (need to fix it); update plume_on_slope results.
1459     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1460    o commit code to make SST/SSS weights spatially variable
1461      (based on either variable in-situ or variable initial T/S weights)
1462    o pkg/ecco:
1463      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1464        now based on horizontally varying weights wthetaLev, wsaltLev
1465      * cost_averagesflags now returns year indices in addition to day, month
1466      * sflux balance is performed on annual basis
1467        (sflxumm, sfluxmm2, bal_sfluxmm)
1468      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1469        including separate counting and multipliers
1470    o pkg/rbcs
1471      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1472    
1473    checkpoint58k_post
1474    o testreport:
1475     - always build in dir. "build" (if not there, mkdir build instead of building
1476       & running in input)
1477     - run in dir run (if it exists), in build otherwise.
1478     - call prepare_run (if input/prepare_run exists)
1479     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1480    o pkg/exf modifications to interpolation and rotation routines for more
1481       reasonable treatment of North Pole singularity: for tracers North Pole
1482       value is set to northernmost zonal-mean value, for zonal velocity it is
1483       set to zero, and for meridional velocity it is set to northernmost value.
1484    o pkg/exf/exf_check_range.F
1485     - add tile index to diagnostics and move stop statement to the very
1486       end of the routine.
1487    o pkg/diagnostics: (diagnostics_main_init.F)
1488      define title of isomorphic variables according to the current config.
1489    o pkg/thsice with pkg/seaice dynamics:
1490    - fix domain of computation (interior only, required for exf) and do exchanges
1491    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1492    o towards a standard way of dealing with multi-threading in MONITOR
1493      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1494    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1495       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1496    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1497    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1498    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1499       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1500    o tracer advection:
1501     - clean-up and simplify calc_common_factors.F
1502     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1503       advection subroutine (but still not used within DST advection S/R)
1504    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1505    
1506    checkpoint58j_post
1507    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1508      from file (collects calls previously in FORWARD_STEP)
1509    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1510    o adjoint store dir. adjusted accordingly
1511    o genmake2
1512      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1513    
1514    checkpoint58i_post
1515    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1516      on wind stress (SEAICEstressFactor defaults to 1.)
1517    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1518      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1519    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1520      on CS-grid: no longer loosing mass.
1521    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1522    o pkg/ggl90: fix sloppy output and fix a bug
1523    o pkg/seaice: added SEAICEuseEVPpickup parameter
1524      - Set to false in order to start EVP solver with
1525        non-EVP pickup files when using SEAICEuseEVP
1526      - fix sign error in diffusion in seaice_calc_rhs
1527    
1528    checkpoint58h_post
1529    * Modifications for bottom topography control
1530      o replace hFacC by _hFacC at various places
1531      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1532      o add non-self-adjoint cg2d_nsa
1533      o update autodiff support routines
1534      o re-initialise hfac after ctrl_depth_ini
1535      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1536    * Adding verification for 5x5 box (4-layer) bottom topography control
1537    
1538    checkpoint58g_post
1539    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1540       used for mean seasonal cycle, mean diurnal cycle); add an example
1541       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1542    o pkg/ggl90:
1543      - add parameter (minimum surface kinetic energy)
1544      - fix bug (avoiding division by zero)
1545    o couple pkg/thsice to pkg/seaice:
1546      - modify advection in seaice to accomodate new scalar fields to be advected
1547      - only muliDimAdection scheme work with seaice/thsice
1548      - mapping of thsice-variables to seaice-variables, back and forth
1549      - does not break the verification experiments, but does not give the
1550        desired results either
1551    o pkg/seaice
1552      - make (default) second order advection a bit less confusing?
1553    
1554    checkpoint58f_post
1555    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1556      to pkg/seaice):
1557      - new routines thsice_map_exf and thsice_get_exf provide the interface
1558      - add an additional formal parameter to thsice_solve4temp
1559    o pkg/exf:
1560      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1561      - correct Stefan-Boltzmann constant
1562      - new parameter for longwave surface emittance
1563      - separate some stuff from exf_bulkformulae into new routines  
1564        exf_radiation, exf_wind
1565      - add new parameters and constants: longwave emissivity for ocean, ice
1566        and snow, evaporation parameters over ice
1567      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1568        either wind from stress or stress from wind
1569    o pkg/thSIce:
1570    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1571    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1572       and THSICE_CALC_THICKN
1573    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1574    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1575      to make debugging easier.
1576    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1577    o pkg/bulk_force:
1578      - clean-up comments and parameters ;
1579      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1580    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1581      generate new output for test-experiment: aim.5l_cs.thSI
1582    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1583      testreport accordingly
1584    
1585    checkpoint58e_post
1586    o SEAICE_CGRID adjoint done
1587    o R_STAR adjoint implemented.
1588      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1589      * need to sort out init. of h0facc, etc.
1590    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1591      to be able to use it in pure forward.
1592    
1593    checkpoint58d_post
1594    o upgrade simple test-experiment to tutorial example:
1595     step.1: duplicate the experiment and (step.2) will remove the old copy.
1596      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1597      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1598      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1599      tutorial_global_oce_biogeo    <- copy of dic_example
1600      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1601      tutorial_plume_on_slope       <- copy of plume_on_slope
1602      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1603      tutorial_global_oce_optim     <- empty for now (David ?)
1604      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1605     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1606    o correct a sign problem in cost_scat.F
1607    o obcs and ptracers: fix boundary conditions for advections schemes
1608      with larger stencil
1609    o thsice adjoint: start
1610    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1611      completeness
1612    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1613      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1614    o ptracers adjoint:
1615      * avoid extensive recomputatations
1616      * fix missing re-init. of gptr (missed by TAF)

1618      me to turn off the excessive output to STDOUT that this package produces
1619    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1620      and add those terms in Vector-Invariant formulation.
1621    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1622      if the control period (xx_hfluxperiod etc) is 0
1623    o in profiles pkg, clean routines and fix details
1624    o in ecco pkg, reading ssh data:

1627    o new package prifiles:
1628      code to compute profile-based cost by Gael Forget
1629      (modifs in ecco, ctrl, autodiff)
1630    o Benign bug fix in initialization (spotted by M. Mazloff) of
1631      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1632    
1633    checkpoint58c_post
1634    o adjoint: finish NLFS adjoint and provide reference output in
1635      verification/global_ocean.90x40x15/results_ad_nlfs
1636    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1637      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1638      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1639      with SEAICE_CGRID defined.
1640    o move calendarDumps from "data" to "data.cal" and clean-up the code
1641      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1642    o add useEXF & useCAL flags (for now, set in hard-coded way)
1643    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1644      (were missing in NH mode, and wrong in quasihydrostatic mode).
1645      waiting for Chris updated version of calc_gw to add those CALLs.
1646    o fix bug in quasihydrostatic S/R ;
1647      add a test for this option: global_ocean.90x40x15.qshyd
1648    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1649      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1650    o add on/off flag useOffLine for package OFFLINE
1651    o seaice:
1652      - modify advection so that it works also on the C-grid
1653      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1654        problem in multi-tile runs with C-grid
1655      - add flags for clipping ice velocities and/or masking solver forcing
1656      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1657        C-grid solver
1658      - added a few comments to seaice_diffusion.F
1659      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1660        are now exclusive)
1661      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1662        required re-ordering the code a little:
1663       + make DAIRN global variable (defined in SEAICE)
1664       + move computation of the viscosities eta and zeta into a new separate
1665         routine (because I need to recompute them in seaice_ocean_stress.F)
1666    
1667    checkpoint58b_post
1668    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1669      update output.txt of exp. aim.5l_cs.thSI
1670    o various mnc cleanups and improvements:
1671      + shrink lookup tables by factor of ~4
1672      + better error reporting when running out of lookup space
1673      + able to handle longer path/file names (up to 500 chars)
1674    o adjoint:
1675      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1676      - TBD: "hidden" mom_vecinv recomp. in dynamics
1677    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1678     (allow to differentiate between forcing components using new integer flags:
1679      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1680     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1681    o ecco
1682      - enable trend removal from SSH anomaly obs.
1683    o adjoint
1684      - a fix for PmEpR when #undef EXACT_CONSERV
1685      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1686      - try to fix "hidden" recomp. in forward_step for NLFS
1687        (NLFS seems broken sometimes after I checked it in)
1688    o seaice:
1689     - add c-grid version of the dynamic solver:
1690       + three new routines that are the c-grid substitute lsr, dynsolver
1691         and ostres
1692       + put a few fields that were local to dynsolver into global common
1693         blocks, so that I can move the computation of stresses etc into
1694         seaice_lsr (saves coding but may break the adjoint).
1695     - replace more hardwired parameters by runtime parameters
1696     - add ice masks that mask the rhs of the implicit solvers where there
1697       is no ice (commented out in seaice_dynsolver, because i am not sure
1698       if this works properly), eventually this should replace the clipping
1699       of ice velocities in seaice_dynsolver to +/-40cm/s.
1700    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1701      include it only where its needed
1702    o move balancing of fluxes before the call of external_forcing_surf
1703    o seaice:
1704      - correct units of turning angles (now they are really in degrees)
1705      - move computation of GWATX/Y out of main routine into dynsolver
1706      - initialize GWATX/Y in seaice_init
1707    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1708      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1709    o seaice: add runtime flags for turning angles (default to zero)
1710    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1711      and trend from exf forcing and ctrl control adjustments
1712    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1713      (since checkpoint57x_post)
1714    o change the default rotation period to 86164.s = the Earth rotation
1715    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1716      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1717    o seaice advection: add code for choosing between the default (2nd order
1718      central differences) and multiDim advection schemes provided by
1719      pkg/generic_advdiff
1720    o seaice:
1721      - removed all references to SEAICE_GRID.h fields from
1722        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1723        (cubed-sphere configuration will change a little)
1724      - grid computations in seaice_init are obsolete now.
1725      - cleaned up code a little so that is easier to read (hopefully).
1726      - added new (better?) discretizations of default advection and diffusion
1727        (turn on with SEAICEuseFluxForm)
1728      - replace 1 in 3d global fields by kSurface in growth.F
1729      
1730    checkpoint58a_post
1731    o seaice:
1732      - bug fix in advect.F
1733    o shelfice:
1734      - separate shelfice load anomaly from pload (breaks with time
1735        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1736        Its default is 0., but it may be computed more cleverly from (unknown)
1737        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1738        done offline. A good approximation of the pressure load anomaly is
1739        necessary to avoid large initial adjustment processes underneath
1740        deep-reaching shelfice.
1741      - small fix in ISOMIP shelfice_thermodynamics
1742      - add more sophisticated thermodynamics of Hellmer (1989), this is
1743        now the default
1744      - give a few constants more intuitive names
1745    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1746      if bulk formulae are used in long integration (especially EmPmR). Turn
1747      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1748      if balancePrintMean, the imbalance that is substracted is printed to
1749      STDOUT.
1750    o fix bug (typo) in obcs_apply_eta.F
1751    o add a new package shelfice which enables us to model the circulation
1752      underneath shelf-ice with draughts of hundreds of meters.
1753     - works
1754     - to do: + include improved thermodynamics
1755              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1756                instead of new field kTopC
1757              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1758                instead of new field R_shelfIce and new code in ini_depth.F
1759                and ini_mask_etc.F?
1760              + adjust vertical mixing schemes?
1761    o seaice pkg:
1762     - add a cpp-flag to include a simple formula for a salinity dependent
1763       freezing point of sea water at the surface
1764     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1765       meridional stresses are now different (and hopefully correct)
1766    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1767       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1768       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1769    o pkg/diagnostics: add options and parameters for regional-statistics
1770       diagnostics ; define regions by reading a region-mask from a file
1771       (might add other options later)
1772    o pkg/bulk_force:
1773     - add option and parameters to use AIM surface-flux formulae.
1774     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1775       others forcing fields (defined in PARM05, parameter file "data") are loaded
1776       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1777     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1778     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1779     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1780       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1781     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1782    
1783    checkpoint58
1784    o add "--embed-source" option to genmake2 which, when the supporting
1785      tools can be compiled (as determined by genmake2) will turn on the
1786      embed_files package which then embeds the entire MITgcm source code
1787      (*.[fFhc] + Makefile) used for the build within the executable
1788      - requested by CNH but off by default
1789      - adds a paltry <9MB to the mitgcmuv executable in most cases
1790      - only writes the output when useEMBEDSRC in eedata is true
1791    o clean up 3-dim. relaxation codes:
1792      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1793      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1794      * Thanks to Tom Haine for testing!
1795    
1796    checkpoint57z_post
1797    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1798      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1799    o fix the pickup behavior for obcs in combination with ptracers
1800    o fix a bug in ptracers_external_fields_load
1801    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1802      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1803    o transfered surface NH pressure to eta field (if exactConserv).
1804    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1805         and update lab_sea output.txt file.
1806    o completing 3-dim. relaxation code: additional term
1807         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1808      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1809      * At compile time, in "EXF_OPTIONS.h" set
1810          #define  ALLOW_CLIMTEMP_RELAXATION
1811          #define  ALLOW_CLIMSALT_RELAXATION
1812      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1813          tauThetaClimRelax3Dim = 15552000.0,
1814          tauSaltClimRelax3Dim  = 15552000.0,
1815      * 3 cases:
1816          1) Use a constant-in-time 3-dim. field
1817          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1818          3) Real-time relax. to time-evolving prescribed field
1819    o Adding Laplacian-type smoothness constraint on
1820      initial and boundary (forcing) controls (ic, bc)
1821      * enable at compile-time via
1822        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1823      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1824      * Absolute scale somewhat unclear so far
1825      * no area weighting was included since no other cost term does so far
1826    
1827    checkpoint57y_post
1828    First step for a NLFS adjoint
1829    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1830    o new init. routines for calc_r_star, calc_surf_dr
1831    o still need to deal with ini_masks_etc
1832    o testreport seemed happy
1833    checkpoint57y_pre
1834    
1835    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1836    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1837    o add new offset feature to offline pkg (plus minor cleanup)
1838    o cfc fixes for final year of integration
1839    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1840      be in GCHEM_OPTIONS).
1841    
1842    checkpoint57x_post
1843    o fix testreport Pb in multiple test experiment.
1844    o cleanup our namelist syntax in verification:
1845      - make it more F95 standards compliant (some work still needed)
1846      - allows the vast majority of our tests to work with gfortran
1847    o Non-Hydrostatic:
1848     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1849     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1850    o Allow to apply AB on T,S rather than on AB(gT,gS):
1851     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1852     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1853       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1854     - need a "clever" read_pickup to restart from the other AB formulation
1855    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1856    o remove some unused variables (reduces number of compiler warnings)
1857    o adjoint
1858      * Disable useVariableViscosity for adjoint for time being
1859        (there are a number of extensive recomputations)
1860      * Initialize certain variables needed for adjoint
1861    
1862    checkpoint57w_post
1863    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1864                 fix the singleCpuIO RS version of MDSWRITEFIELD
1865       and add a WARNING if using globalFiles=T with multi-processors.
1866    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1867      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1868    o tracer advection scheme:
1869      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1870       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1871       was not very convenient).
1872      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1873       (further tests needed for the implicit DST & Flux-Limiter schemes).
1874    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1875      and sRef for convenience, handy, when you want to initialize
1876      ptracers in a large domain with a constant non-zero value. Also,
1877      untangle ptracers_init.F a little.
1878    
1879    checkpoint57v_post
1880    o change dome exp. to use variable viscosity in side-drag terms.
1881    o remove all the files from the cfc_offline test since they are now
1882      incorporated into tutorial_cfc_offline which has been producing
1883      identical results for a few days of testing
1884    o add new parameter: sideDragFactor to enable half-slip-side BC
1885      and change side-drag S/R to use viscosity from mom_calc_visc
1886      (can switch back by setting sideDragFactor=0.); affects results at
1887      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1888       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1889    o vorticity & strain are now computed without masking, to account for
1890      no-slip-side BC in variable viscosity calculation ; mask is applied
1891      anyway later on, before computing advection/coriolis terms.
1892    o modify exp4 to test new obcs support for reading from external files
1893      and for passive tracers
1894    o fix behavior of ptracers_monitor when monitor output is written to a
1895      netcdf-file; still not independent of monitor.F (writes in the same
1896      file).
1897    o change default value of tRef (put a uniform, meaningful value for ocean
1898      & atmos) and initialize sRef (was missing, as Martin mentioned).
1899    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1900      to be proportional to enstrophy dissipation length.  Thus,
1901       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1902      This is now consistent with Smagorinsky and with the manual.
1903    
1904    checkpoint57u_post
1905    o OBCS and PTRACERS: add open boundary support for passive tracers
1906      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1907        OB-values from file; this is not different from the way theta and salinity
1908        are treated
1909      - however, Orlanski-radiation conditions are not supported, and the model
1910        will stop if you use pTracers and Orlanski at the same time.
1911      - beefed up the rountine obcs_external_fields_load: now only those open
1912        boundary values are overwritten with values from files for which there
1913        are really files, otherwise the OB-fields remain untouched. This makes
1914        it possible to use different OBs at different ends of the domain (as
1915        with EXF)
1916    o reduce number of exch calls in shap_filt (s2).
1917    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1918      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1919    
1920    checkpoint57t_post
1921    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1922    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1923      same truncation, independent of the face number: affects affects several
1924      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1925    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1926      note that biharmonic viscosity + no-slip was not tested in any experiment.
1927    o fix bug in non-linear free-surf side-drag ; generate new output for
1928      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1929    o make mnc honor the writeBinaryPrec flag for most kinds of output
1930    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1931    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1932      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1933    o add brackets in multi-terms sum to get same truncation, independent of
1934      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1935      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1936    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1937      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1938      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1939      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1940      Suggested values of viscosity parameters found in mom_calc_visc.
1941      Many new viscosity diagnostics available.
1942    
1943    checkpoint57s_post
1944    o Add clearing-house for viscosity calculations, mom_calc_visc and
1945      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1946      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1947      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1948      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1949      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1950      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1951      ViscAhStrain and viscAhTension are now retired.
1952    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1953    o In response to JMC's bug report, genmake2 now ignores any soft-links
1954      that it finds in the *current* directory when searching for files.
1955      Soft-links found in any other source directories will still work as
1956      they did before.
1957    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1958      a C routine to unlimit the stack size
1959    o mnc-ify pkg/aim snapshot vars
1960    o mnc-ify pkg/land as requested by Daniel
1961    o various changes to mnc including:
1962      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1963      - output can now be grouped so that all files within a group
1964          change the ITER portion of their names in lock-step together
1965      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1966          and works with both EXCH1 and EXCH2 (but needs more testing)
1967      - writing works for all verification test cases w/ g77 on Linux
1968    
1969    checkpoint57r_post
1970    o make MNC variable initialization happen earlier
1971    o add diagnostics for (almost) each term of the momentum Eq.
1972    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1973    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1974    o remove MINIMAL_TAVE_OUTPUT option ;
1975      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1976    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1977      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1978    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1979    o add time-dependent SST, SSS control
1980    o cost terms in ecco/ modularized (new cost_generic.F)
1981    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1982    o new infrastructure for seaice model vs. obs misfits in seaice/
1983      * driver from the_main_loop.F is seaice_cost_driver.F
1984      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1985      * gradient check in Exp. 6a of natl_box_adjoint/
1986    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1987      (see README file)
1988    
1989    checkpoint57q_post
1990    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1991    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1992      - bug was reported by Jean-Michel and Ian Fenty
1993    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1994      update exp. cpl_aim+ocn output.
1995    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1996      Needed for high-res. runs with large global files
1997      to be able to limit tapelev size
1998    o Changed some tests for adjoint:
1999      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
2000      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
2001      * global_ocean.90x40x15/ back to default 3-level checkpointing
2002    o Modifications to enable scripted COMMON to MODULE conversion
2003      * verification/OpenAD/code/ has necessary scripts and description;
2004      * converts, compiles and runs successfully;
2005    
2006    checkpoint57p_post
2007    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
2008    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
2009      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
2010    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
2011    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
2012      (was already the case for dissipation with mom_vecinv,
2013       and also the case for grad.PhiHyd when staggered-timeStep)
2014      This will allow to put dissipation out-off the AB time-stepping.
2015     Unfortunately, affects truncation error. Update output of exp. that "fails"
2016      (cg2d matching number) and leave the others for later: front_relax(10),
2017      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
2018      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
2019    
2020    checkpoint57o_post
2021    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
2022      (2) its ready to be documented during the 20050801 DocFest
2023    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
2024      for ideal_2D_oce and lab_sea on linux_ia32_g77
2025    o set to #undef CTRL_SET_OLD_MAXCVARS_30
2026      in global1x1_tot/code_seaice_adj to access indices 32, 33
2027      (worth another tag)
2028    
2029    checkpoint57n_post
2030    o adding precip control xx_precip 32
2031    o adding swflux control xx_swflux 33
2032    o Replacing 10 forcing penalty cost routines by 1 generic.
2033    o Implementing partitioning in time-mean and variable adjustment
2034      for atmos. state.
2035    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
2036  o in natl_box_adjoint:  o in natl_box_adjoint:
2037    * updated: results_bulk/    * updated exp 1 to 10
2038    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
2039    o updated global1x1/*_seaice_adj/
2040      to incorporate latest changes
2041    o enable useSingleCpuIO for mdsio vector routines
2042      (applies in particular to tapelev I/O)
2043    o removed inefficient K-loop in all active_file*control*.F
2044    
2045  checkpoint57m_post  checkpoint57m_post
