4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  checkpoint61q
8  o moved ptracer ctrl index 17 -> 32  o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
9     - the boundary conditions along open boundaries are unclear, because the
10       associated masks are set to zero and are thus treated as closed when
11       applying the slip-boundary conditions.
12     - move initialisation of grid variables from seaice_init_varia to _fixed
13    o adding doc/diags_changes.txt
14    o model/src:
15      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
16       to avoid "_diags" naming if no relation to pkg/diagnostics.
17      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
18       file and only call PLOT_FIELD_XYZ if debugMode=T.
19      remove few PLOT_FIELD_XY calls outside initialisation.
20      remove few unnecessary BARRIER.
21    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
22      of salt_plume package in Southern Ocean
23    o pkg/thsice:
24     - fix hOceMxL in overlap (needed for sea-ice advection);
25       update output of experiment global_ocean.cs32x15.icedyn.
26    o pkg/seaice:
27     - make the (placeholder-)tracer IceAge a little more meaningful
28      by avoiding ridging of age due to convergent ice flow
29     - add diagnostics for surface temperature, atmospheric and oceanic
30       heat flux, and atmospheric and oceanic ice growth
31    
32    checkpoint61p
33    o eesupp (global_max & global_sum):
34     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
35     - remove starting & endding barrier (no longer needed)
36    o pkg/mdsio, writelocal:
37       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
38       (remove the STOP): uses shared buffer IO to store data from all threads
39       and then let master-thread write nThreads tiles.
40    o pkg/mdsio (read/write field):
41     - tiled IO done in 1 piece (all levels at a time);
42     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
43     - multi-threaded: allow to read/write local (non-shared) array
44       (was already working with singleCpuIO ; now works also without);
45       => no longer needs barrier call after reading a file (added inside
46       mds_read/write field).
47     - move barrier calls outside gather/scatter_2d to mds_read/write_field
48    o pkg/obcs/exf
49      - exf_getffieldrec.F: add a few ". _d 0" and
50                            add code to catch the case fldperiod = 0.  
51      - obcs_precribe_read.F: change if statements so that they match
52                              the variable type (_RL)
53      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
54        exf_iprec) as part of namelist EXF_NML_01
55    o pkg/mdsio:
56      - read/write tiled (local) files: read/write 1-level tile chunk at a time
57        (instead of segment of length sNx); expected to speed up tiled IO.
58    o pkg/exch2:
59      - take buffer copy from/to array out of S/R exch2_send/recv into new
60        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
61        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
62      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
63      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
64        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
65        including Topology header file (and common blocks).
66      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
67        remove 2nd exch call in exch2_s3d_rx (no longer needed).
68      - document S/R arg. list (+ update some comments)
69    o pkg/seaice:
70      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
71        temperature and humidity over sea ice based on climatological values.
72      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
73        of LSR (this change is expected to change the results slightly because now
74        it uses slightly difference moduli from the second last LSR solution, but
75        that is more consistent with the stress computations; this part of the code
76        is not tested in the verification experiments)
77      - fix diagnostics for flux of ice in case of B-grid
78      - turn strain rates eij and press into global fields within global
79        common block in SEAICE.h for more straighforward diagnostics
80      - fix diagnostics for principal stress components, press, zeta, eta
81        to give something meaning full
82    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
83      new output (all 4 tests) using default rotationPeriod.
84    o pkg KPP:
85      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
86      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
87        and normal grid from 1 to Nr)
88    o Fix computations of L4rdt in mom_calc_visc.F
89    o eesupp:
90      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
91      should be called before a "stop" if we know that all process are going
92      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
93    
94    checkpoint61o
95    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
96    o model/src/ini_curvilinear_grid.F:
97       compute angleSin/CosC when they are not read from a file
98    o pkg/seaice:
99       add pseudo time stepping for LSOR
100    o pkg/exch2:
101       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
102    o pkg/seaice:
103       Adding separate sea ice albedo, drag coefficients, and HO in Southern
104       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
105    o SingleCpuIO:
106       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
107    o pkg/seaice:
108       put exchanged variable in (local) common block for MPI+Multi-Threads
109       to work (necessary with exch1, and for now with exch2 too).
110    o verification: to get more experiments tested with mpi, mth and mpi+mth,
111      change tiling of:
112       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
113       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
114      update output of exp:
115       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
116       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
117      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
118                       (note: output.txt generated on faulks using only 1 tile)
119    o eesupp & mdsio (SingleCpuIO):
120     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
121       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
122       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
123     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
124     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
125       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
126    o pkg/exch2:
127     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
128       read parameter file "data.exch2" if it exists; otherwise try default regular
129       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
130     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
131       with new code (not to be used, just as a backup solution).
132     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
133       in utils/exch2/input.
134    
135    checkpoint61n
136    o eesupp & mdsio (SingleCpuIO):
137      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
138        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
139        receive real*4 array (instead of real*8) to read/write 32.bit files.
140        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
141         and remove new mapping S/R)
142    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
143      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
144        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
145        when using exch2. Add S/R to map global io-buffer to global model array.
146      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
147    
148    checkpoint61m
149    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
150      and add 3 other S/R for other types (R4,R8,RS).
151      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
152    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
153     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
154     - reduce number of macro definitions (keep only those which are used);
155       can always call directly the corrresponding S/R if needed.
156     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
157       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
158     Fixed wrong type of arg in:
159       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
160       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
161     To fix: global_sum of var in common block is wrong (multi-threaded) in:
162       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
163     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
164    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
165      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
166    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
167    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
168      edges are closed (zero depth); might happen with "blank tiles";
169      for now, disabled if using OBCS.
170    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
171      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
172    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
173      to reduce length of 1.D array print in STDOUT.
174    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
175      + use 48 tiles (16x8): this will allow to test "blank tiles".
176    o start to test MPI + multi-threaded (change testreport to skip tests
177      where number of tiles do not match).
178    o genmake2: add option "-omp" to turn on Open-MP ;
179      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
180    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
181      and keep the original tile numbering. Note: compatible with old
182      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
183    
184    checkpoint61l
185    o Overlaps had been forgotten in calculating ijk keys : fixed
186    o fix cyrus makedepend for gcc 4.4
187    o experiment fizhi-cs-aqualev20:
188      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
189      and generate new output. Note: new output is much closer to the old
190      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
191      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
192    o pkg/fizhi:
193     - change to avoid indices going deliberately over array-bounds
194     - remove unnecessary MPI stuff
195     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
196     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
197       does not go over array-bounds and therefore returns reliable output.
198     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
199       this S/R has 4 output arguments, which are used inside "get_alarm";
200       when it is called with the same variable "ndum" in place of several
201       output arguments, this produces weird side effect inside "get_alarm"
202      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
203       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
204       address) and produces error.
205    o tools/gemake2: (March 27-29 2009)
206      with option "-mpi": link *_mpi files from "MODS" dir (this is what
207      testreport does).
208    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
209    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
210       update lab_sea.lsr & lab_sea.salt_plume results
211    o pkg/seaice:
212      Major overhaul of the LSOR solver: change discretization from original
213      finite differences to finite volume. The old routine is still in the
214      file seaice_lsr.F and can be turned on with the CPP-flag
215      SEAICE_OLD_AND_BAD_DISCRETIZATION
216      Along with this change, the discretization of the strain rates is changed.
217      The same flag turns on the old discretization in seaice_calc_strainrates.F
218      All verification experiments with seaice are affected (except for
219      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
220      results by setting the above flag.
221      Further changes involve changes in defaults:
222      - ALLOW_FLOODING is defined and turned on by default
223      - SEAICEadvSnow = .true. is now the default
224      - SEAICEadvSalt = .true. is now the default
225      - SEAICEadvAge  = .true. is now the default
226      - SEAICE_clipVelocities  = .false. is now the default
227                                         (as per J. Zhang's recommendation)
228      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
229        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
230      - seaice_growth: replace computation of UG by a simple copy from wspeed
231    
232    checkpoint61k
233    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
234      seaice_lsr: fixed a few metric terms,
235                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
236                  add more debugging diagnostics
237      seaice_evp: removed superfluous many metric terms of FV discretization
238                  of stress divergence
239                  affects lab_sea, lab_sea.hb87
240      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
241                  of stress divergence for non-evp solver
242                  (this part is not tested anywhere)
243      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
244                  they were effectively only half slip
245                  affects lab_sea.hb87
246      updated all relevant verification experiments (except lab_sea//output_adm.txt
247        which was left over, but fails at level 7 & 6)
248    
249    checkpoint61j
250    o pkg/seaice: turn a few hard wired parameters into run time parameters
251    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
252      time in seconds as promised by the usints in seaice_monitor and exf_monitor
253    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
254      that are not cubed-sphere grids
255    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
256    o pkg/ctrl:
257      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
258    o non-hydrostatic (calc_gw.F):
259      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
260      update output of exp. global_ocean.cs32x15.viscA4
261    o remove backward compatibility for thetaMin,phiMin
262      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
263    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
264      interpolated wind field not only for curvilineargrid=.true., but also
265      for a rotated grid (rotateGrid=.true.)
266    o pkg/exf: add capability to bypass interpolation for runoff
267      by setting yet another CPP-flag
268    o eesupp/src, B-grid exchange:
269      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
270    o autodiff
271      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
272      allows to switch to single-prec common blocks;
273      corresponding switch occurs in tamc.h, integer isbyte
274      TAF store directivs "byte" and "kind" seem equivalent;
275      Most tamc.h have been updated correspondingly.
276    
277    checkpoint61i
278    o autodiff:
279      fix autodiff_sore/_restore indices for obcs
280      (spotted by I. Hoteit, M. Mazloff)
281    o pkg/autodiff, pkg/ctrl:
282      Add flag to reduce all tapelev I/O to single-prec.
283      In data.ctrl set
284        doSinglePrecTapelev = .TRUE.
285    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
286      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
287    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
288      real fresh water flux (not yet)
289    o pkg/mdsio & rw:
290     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
291     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
292    o pkg/flt:
293     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
294       init_fixed & ini_varia.
295     - clean-up & simplify linear interpolation S/R:
296       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
297     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
298     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
299     - add vert. coordinate & horiz. indices to output files.
300     - change vertical position in initial condition, from index to depth [m].
301     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
302       (easier to get to a curvilinear grid) ; delX,delY no longer used.
303    o pkg/ggl90: a few modifications:
304     - fix bottom boundary condition, and interpolation of KappaE
305       near top and bottom
306     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
307     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
308     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
309    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
310      (maintain temporary backward compatibility, until next checkpoint)
311    
312    checkpoint61h
313    o pkg/diagnostics with "periodic averaging diagnostics":
314      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
315    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
316    o pkg/obcs: fix loop ranges for balancing code
317    o pkg/flt:
318     - improve criteria for finding which tile owns a float.
319     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
320    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
321      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
322      with ocean biogeo)
323    o pkg/flt:
324     - do some cleaning and fix the restart ;
325     - add output.txt in flt_example/results to get this pkg tested.
326    o genmake2: add an EXTENDED_SRC option and flag.
327       for now, cannot be turned on on command line (only through genmake_local)
328    o pkg/mdsio: read/write vector:
329     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
330     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
331       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
332     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
333      (drop to 4 digits matching for grad). But this test does not look very
334      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
335    
336    checkpoint61g
337    o pkg/flt:
338      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
339       + make OPTIONS file more standard.
340      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
341      - fix _BYTESWAPIO CPP-Flag
342      - standard reading of file-parameter "data.flt"
343      - fix argument list of S/R FLT_RESTART
344      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
345    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
346    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
347      a still unfixed compiler/optimization bug
348    
349    checkpoint61f
350    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
351      update results of global_ocean.cs32x15.icedyn test.
352    o move getcon.F from model/src to pkg/fizhi.
353    o pkg/exf: add parameter for extrapolation of temp up to the surface
354       and option to prevent negative evap (in bulk_largeyeager04 only).
355    o Prather Advection scheme: fix tracer conservation for divergent flow
356      (e.g., when using NonLin Free-Surface).
357    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
358    o gmredi (Visbeck-variable-K):
359     - add more parameters to Visbeck-variable-K.
360     - use a 5 points average for dSigmaR in Visbeck-K calculation
361       (more "homogenous": same stencil and same weights as in dSigmaH)
362     - update output of ideal_2D_oce experiment.
363    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
364      (#undef REAL4_IS_SLOW)
365     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
366       coordinate variable
367     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
368       (surface forcing fields), removes some of the functionality
369     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
370     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
371       probably not all: copy _RS surface flux fields to RL field before
372       calling DIAGNOSTICS_FILL
373     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
374       real*4 (CALL EXCH_*_RS) versions.
375     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
376       (generate new output).
377    
378    checkpoint61e
379    o gmredi (Visbeck-variable-K):
380      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
381      - change computation of Visbeck-K where Slope > Smax :        
382        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
383        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
384    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
385      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
386    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
387    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
388      does not become too large (to avoid precision problems in implicit-diffusion
389      solver); update ideal_2D_oce output.
390    o pkg ggl90:
391      - in ggl90_cal.F: compute only one set of visc/diff, used to
392        step forward TKE/T/S/momentum
393      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
394        have Prandlt =1)
395    o gmredi (fm07):
396      - add lower limit on Transition layer thickness + lower limit on 1/lambda
397      - allow to set few more params from data.gmredi
398    o pkg ggl90:
399          - add missing sqrt(2) factor in computation of mixing length
400            scale in ggl90_calc.F
401            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
402    
403    checkpoint61d
404    o adjoint modifs
405      - adapt to new field rhoInSitu
406      - allow to revert from StoreDynVars2D, StoreDynVars3D
407        to individual fields
408        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
409    o store 3-D (in-situ) density in commom block (DYNVARS.h)
410     - save 1 rho computation.
411     - no longer modify T & S inland when using down_slope pkg.
412    o gad_som : allow to switch to SOM advection for T & S without corresponding
413      pickup files (using new S/R: MDS_CHECK4FILE).
414    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
415      (for useSingleCpuIO to work in multi-threaded)
416    o pkg/shelfice:
417     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
418       with SHELFICEtopoFile in data.shelfice
419     - move code for reading ice shelf topography and modifying hFacC into separate
420       subroutines of the shelfice package
421     - separate initialisation of "fixed" and "variable" variables
422     - kTopC is not (yet) replaced by kSurfC, although this is possible
423    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
424    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
425      and rename:
426      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
427      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
428    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
429    
430    checkpoint61c
431    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
432      to add mass source/sink of fluid in the interior (3-D generalisation
433      of oceanic real-fresh water flux).
434    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
435    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
436    o new pkg: down_slope
437      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
438      - presently, modify T & S inland (dwnslp_calc_rho.F).
439        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
440      - implementation for ocean in P-coords not tested.
441      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
442    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
443      (to facilitate conversion of oceanic pkg to p-coordinate).
444    o change FIND_RHO to FIND_RHO_2D :
445      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
446    o new pkg: cheapaml
447    
448    checkpoint61b
449    o exch2:
450      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
451      - no longer depend on the order sequence (N,S,E,W).
452      - 3rd exchange no longer needed (tested with 24 tiles).
453      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
454      - exch_UV_A-grid readily available (but not yet tested).
455      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
456      (both are no longer needed) in exch_uv: no effect in forward run; but
457       get truncation error differences with adjoint exch.
458    o exch2:
459     - change index-bounds storage (moved from target to local tile,
460       more intuitive this way) ; rename/remove some variables.
461     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
462    
463    checkpoint61a
464    o exch2/matlab-topology-generator:
465      fix bug in index bounds for N-S internal exchange (hard to tell if this
466      had any effect on the solution).
467    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
468      is exceeded
469    o testreport: modify syntax of awk, so that it works also with
470      awk, and not only with nawk and gawk
471    
472    checkpoint61
473    o autodiff
474      Change default for TAF usage by removing argument '-nonew_arg'
475      This changes TAF subroutine argument list (ordering of active var.)
476      Omission of this flag leads to incompatibility w.r.t. TAMC
477      To restore TAMC-compatibility, need following modifs:
478      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
479      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
480      Tested TAF version is 1.9.22
481      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
482    
483    checkpoint60
484    --->>> This is the last checkpoint for which generating the adjoint
485    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
486    --->>> by default.
487    --->>> Future checkpoints will ommit this flag by default.
488    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
489    o pkg/grdchk: Add gradient check to etan0 perturbations.
490    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
491    o pkg/autodiff: more flexibility in zeroadj.
492      model/src: modifying do_oceanic_phys.F accordingly.
493    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
494    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
495      special setup of gmredi for which the adjoint is stable
496      enough for parameter optimization.
497    o bridging the gap between eddy stress and GM.
498      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
499          along with a change in CPP option (now ALLOW_EDDYPSI).
500      -> when using GM w/ GM_AdvForm:
501          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
502          is applied either in the tracer Eq. or in momentum Eq.
503          depending on data.gmredi (intro. GM_InMomAsStress).
504      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
505      The key modifications are in model/src/taueddy_external_forcing.F
506      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
507    
508    checkpoint59r
509    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
510      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
511      fix option to read coriolis(@ cell-corner) from files with CS-grid.
512    o pkg/mnc: add some attributes to standard 1D-coordinate variables
513    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
514      mass points, when using mnc for output
515      - add runtime parameter (missing_value, missing_value_int) to override
516        default (which is the value of getcon('UNDEF'))
517    o pkg/mnc: prepare mnc for the actual use of missing values with the
518      diagnostics package: small fix in mnc_cw_readwrite.template and more
519      initialisation of never used fields
520      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
521      versions
522    o pkg/thsice/thsice_ini_vars.F added default initial values so that
523      thermodynamics sea ice solver does not blow up when some initial fields
524      are missing.
525    o move from external_forcing_surf.F to ini_forcing.F
526      the p-coord. hack consisting in using pLoad to set phi0surf ;
527      update output of tutorial_global_oce_in_p (affected @ truncation level).
528    o Freshen up a bit hs94.1x64x5, notably:
529      remove rotationPeriod and tRef=5*0. (adjoint only), and add
530      exactConserv=.TRUE.
531    o pkg/generic_advdiff:
532      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
533      applies to files where Temperature & Salinity 2nd Order moments are used.
534    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
535      this uses a dynamically allocated internal state data structure
536      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
537      and requires a fortran 90 compiler
538    
539    checkpoint59q
540    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
541       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
542    o Refresh tutorial_global_oce_biogeo, notably:
543      - change bathymetry (put back seamounts in ACC, use hFacs)
544      - change EOS (POLY3 --> JMD95Z)
545      - use Bryan-Lewis vertical diffusivity
546      - use multidimensional advection
547      - remove old virtual virtual in dic pkg, now done through ptracer pkg
548      - change a couple of parameters in dic pkg
549    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
550    o pkg/obcs: change default to OBCSfixTopo = .true.,
551      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
552      - replace "debugMode" with "debugLevel .GE. debLevB"
553    o implementation of TAF directives for gchem,cfc,dic
554    o remove "exp5" (replaced by tutorial_deep_convection).
555    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
556      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
557      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
558      --> changes results in exp4, seaice_obcs
559    o tutorial_deep_convection :
560      update the set-up and increase resolution and domain size ; start
561      from pseudo initial conditions = output at t=120mn in order to see
562      something happening when running testreport.
563    o pkg/seaice: add os7mp as an advection scheme
564                  add check for advection schemes
565                  add a flag for restoring T and S underneath sea ice
566    o pkg/my82: add netcdf-support and diagnostics
567    o thsice pkg:
568      - Now hsMax limits snow height by turning it into ice following
569        flooding scheme (and now conserving energy)
570      - Slight rewriting of the formula in thsice_calc_thick.F
571      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
572      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
573    
574    checkpoint59p
575    o gchem / dic / cfc :
576      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
577      - add new parameter files: "data.dic" & "data.cfc" ;
578      - various re-arrangement in initialisation & header file ;
579      - fix tutorial_global_oce_biogeo for multi-threaded test.
580    o pkg/dic: test for "pickup_dic" file when restarting ;
581      if no pickup-file, can restart with a re-initialised pH (same as it did
582      before) providing pickupStrictlyMatch is set to False.
583    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
584      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
585    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
586      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
587    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
588     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
589       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
590    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
591       scheme to use for vorticty-term ;
592     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
593       (with default selectVortScheme, return to original discretisation)
594     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
595    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
596    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
597      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
598      also fix diagnostics VISCAHW & VISCA4W.
599    
600    checkpoint59o
601    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
602    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
603      move a few statemens out the main loop into separate loops
604    o pkg/shelfice:
605      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
606        (kg/m^2/s), does not break tests, because in verification/isomip,
607        rhoConstFresh=rhoConst (by accident)
608      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
609      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
610        new file model/src/seawater.F, so that they are available for all pkgs.
611      - convert potential temperature into in-situ temperature. This changes the
612        isomip tests => update tests
613    o add a flag writePickupAtEnd (default=true) to be able to suppress
614      writing a pickup at the last timestep
615    o tools/mpack-1.6 :
616      - disable automake (not working) and autoconf (not needed).
617      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
618        also cleaner with much less compilation warnings.
619    o pkg/profiles:
620      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
621      (for "less than 32 characters name" compiler requirement)
622    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
623      conditions that have a different sampling frequency than S/T/U/V obcs
624    o pkg/diagnostics (stats-diags):
625      - fix global Min/Max in case 1 processor get only empty tiles
626    o genmake2: replace (4 times)
627         make genmake_tc_1.o >> genmake_warnings 2>&1
628      with
629         COMM="$CC $CFLAGS -c genmake_tc_1.c"
630         echo $COMM >> genmake_warnings
631         $COMM >> genmake_warnings 2>&1
632      to make genmake2 always see the value of CC as specified in the optfile.
633    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
634      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
635      - modify verification advect_cs test to test SOM-advection on CS-grid.
636    o pkg/ctrl:
637      - Rewrite of ctrl_map_ini_ecco.F,
638        introducing a generic routine (ctrl_map_ini_gen.F).
639      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
640    
641    checkpoint59n
642    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
643      number in dedicate array "hdiag":
644      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
645        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
646      - many small changes (integer format) for large number of diagnostics
647      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
648        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
649    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
650      usingSphericalGrid, this allows to define the rotated grid coordinates
651      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
652      geographical coordinates according to the inverse of the rotation defined
653      by the Euler angles, so that Coriolis parameter and online-interpolation by
654      exf works with the geographical coordinates on XC/YC/XG/YG.
655      Naturally, this feature does not work with all packages, so some
656      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
657      profiles), because there the coordinates are assumed to be regular
658      spherical grid coordinates.
659    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
660      - introduce isopycnal diffusion coefficient control.
661    o tools/adjoint_options:
662      - additional control vector components.
663    o pkg/mnc: have mnc create marginally meaning full coordinate variables
664      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
665    o pkg/mypackage:
666      - add example of read/write pickup for state-var ;
667      - add entry points to the main code for state-vars diags & write-pickup.
668    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
669      transitions for useExfYearlyFields
670      - add new subroutine that determines the file to read from for
671        use*YearlyFields = .TRUE. and .FALSE.
672      - add a verification experiment to global_with_exf that tests
673        useExfYearlyFields with USE_EXF_INTERPOLATION defined
674    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
675      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
676      subroutines (which could be generated from a template, because they are
677      almost identical), for now they are included in obcs_prescribe_read.F for
678      simplicity
679    o pkg/exf:
680      - add a little more diagnostic to exf_interp_read (in analogy to
681        mds_read_field, can be turned off with debugLevel < debugLevA=1)
682      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
683        ugly but fast by unrolling short inner loops, inserting a unroll=8
684        directive in routine lagran, and splitting a loop and making do while the
685        outermost loop (the latter requires the intoduction of index arrays)
686    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
687    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
688      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
689    o verification/seaice_obcs: updated for restart test and latest options
690    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
691      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
692      for now this is only available for the C-grid code and also within
693      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
694    
695    checkpoint59m
696    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
697      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
698    o gad_som : fix flux output (& diagnostics) to have same units as other  
699      advection scheme fluxes (was previously multiplied by deltaT).  
700    o added verification/seaice_obcs both to test seaice open boundaries
701      and to provide an example matlab scrpt for generating them
702    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
703    o pkg/salt_plume: clean up salt_plume_frac.F to
704      remove redundancy in PlumeMethod 1 and 4
705    o pkg/kpp: added saltplume diagnostics
706    o pkg/obcs and pkg/seaice:
707      - do not set uice and vice to zero when OB*icefile are unspecified
708      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
709      - moved seaice tracer obcs after call to seaice_growth
710    o pkg/salt_plume: added various options for salt plume depth
711      criterion and for vertical distribution of the salt
712    
713    checkpoint59l
714    o pkg/ptracers: new version of ptracers pickup:
715      read meta file and write only fields which are needed to restart.
716      ( same logic as main pickup file ; also using pickupStrictlyMatch )
717    o pkg/seaice:
718      - add timescale for melting due to warm mixed layer as a means of
719        setting SEAICE_availHeatFrac more conveniently
720      - add a CPP-flag/runtime parameter check for flooding algorithm
721      - reformulated availHeat in seaice_growth.F to be independent of AREA
722    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
723      unit changes
724    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
725    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
726      SX vector computer.
727    o pkg/seaice:
728      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
729        seaice forcing fields can now be read only through pkg/exf
730      - removed some unused halos
731    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
732    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
733      or U/VICE from U/VWIND before computing U/VSTRESS
734    
735    checkpoint59k
736    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
737      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
738    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
739      all experiments pass when compile with un-initialised var. checking option.
740    o added pkg/salt_plume
741    o script to test restart (for now, in MITgcm_contrib/jmc_script)
742    o pkg/seaice: new read/write pickup version.
743      read meta file and write only fields which are needed to restart.
744      ( same logic as main pickup file ; also using pickupStrictlyMatch )
745    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
746    o lab_sea.hb87: modify the domain & update output.hb87.txt :
747      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
748      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
749      process. Fixed here by closing the domain at the Northern boundary.
750    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
751    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
752      a set of consecutive levels in/from a 3-D array.
753    o pkg/ptracers:
754      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
755      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
756    
757    checkpoint59j
758    o in pkgs: dic, obcs, offline, rbcs:
759      standard way to compute coeff. for time interpolation between 2 time reccords
760      which retains full precision (& make results less dependent on compiler).
761      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
762    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
763      packages instead of reading ice cover and wind speed separately
764    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
765     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
766      to allow to compile customized code before the update)
767    o cleaning-up:
768      - fix CPP instruction syntax in pkg/obcs
769      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
770        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
771      - fix some threads issue in IO parts.
772    o pkg/dic:
773      - add tons of "_d 0" (--> much better testreports !)
774       and then update outputs of tutorial_global_oce_biogeo
775    o pkg/mom_fluxform:
776      add a special version of momentum advection intended to conserve momentum
777      next to a bathymetry step or a coastline edge. (default = off = #undef)
778    o new read/write pickup version:
779      - for now, only implemented for main (mdsio) pickup file.
780      - write out only what is needed to restart; merge pickup_nh , pickup_ph
781        and main pickup together.
782      - read meta file; read only what is needed to restart; stop if a field
783        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
784        if it make sense (even if the restart is not perfect).
785      - if no meta file, assume that pickup to read corresponds exactly to
786        a pickup that would currently be written.
787      - read pickup written in the old format (until checkpoint59i) if it
788        recognizes an old meta file (no field-list).
789      - add a meta file in exp. which starts from a pickup: 2 cases:
790        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
791         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
792        b) a meta file describing the content of the associated pickup file
793         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
794    o pkg/mdsio & pkg/rw:
795      - new routine to read a meta file ; new set of routine to read
796        Multiple-fields file (with meta file).
797    o added open boundary conditions capability for seaice
798        HSNOW, HSALT, UICE, and VICE
799    
800    checkpoint59i
801    o adjoint:
802      * fix multiDimAdvection adjoint
803        (partial recomputation problem by TAF for fVerT(:,:,kDown)
804        and comlev1 size definition (maxpass vs. max. number of tracers)
805      * verification/global_ocean.90x45x15 adjoint now tests
806        NLFS and multiDimAdvection using DST3 (=30)
807      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
808    o pkg/kpp: add "_d 0" to real constant (if missing);
809      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
810      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
811    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
812      for internal parameters related to restart process (formerly from PARAMS.h)
813      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
814    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
815      as argument. (only atm2d & obcs write_pickup have not yet been updated)
816    o pkg/monitor:
817      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
818      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
819      - account for deep Atmosphere factor and density factor (anelastic)
820    o added open boundary conditions capability for seaice HEFF and AREA
821    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
822      thermodynamics
823      - requires a little reorganization, which affects the testreport results
824        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
825        so that now the conservative form is tested
826      - add a few comments
827    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
828    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
829    o add new diagnostics to seaice: advective, diffusive fluxes (only for
830      multidim-advection, for scheme 2 they are not filled) and transports,
831      thermodynamic growth rates
832    o change units of EmPmR (inside the code, + within coupling interface)
833      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
834      Affects results @ truncation level (cg2d match) and update output of
835       experiments: lab_sea(6), global_ocean.90x40x15(10),
836      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
837      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
838      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
839      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
840    
841    checkpoint59h
842    o pkg/exf:
843      - improve vectorization by moving if-statement out of loops in
844        exf_mapfields, exf_radiation
845      - exf_bulkformulae.F: introduce 2D fields and vectorize code
846    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
847    o testreport:
848      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
849        monitor & update offline_exf_seaice exp. output.
850      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
851    o pkg/seaice:
852      - bug fix in the evp solver: boundary conditions were affected be
853        masking of zMax/zMin (changes results)
854      - minor bug fix in boundary conditions in seaice_calc_strainrates
855        (changes results for no_slip)
856      - seaice_lsr.F: make interpolation of eta dependent on boundaries
857      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
858      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
859        stress formulation and no-slip boundary conditions
860    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
861      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
862    o pkg/seaice: a first HSALT time stepping equation has been checked in
863    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
864      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
865      without requiring DO-IF statements
866    o pkg/thsice:
867      use continuous power-law function for partition of energy between lateral
868      melting/freezing and thinning/thickening ; old code using step function
869      still available with #undef THSICE_FRACEN_POWERLAW
870      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
871    o testreport: change AD testing : check against results/output_adm.txt
872      using same scripts as for forward test.
873    
874    checkpoint59g
875    o adjoint testing: in preparation for changing testreport:
876      - output format: cost and grad written on separated lines
877      - ad output results in directory "results" (instead of "results_ad")
878    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
879    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
880    o pkg/ecco: allow user defined cost function contributions
881    o testreport:
882      Allow to choose (per experiment) the list of tested output variables
883       and the main variable (used to issue a pass/FAIL ) ;
884      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
885      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
886      Also modify printing of summary:
887       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
888       b) echo the list of tested variables in the individual summary.txt of
889          each experiment.
890    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
891      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
892      (but still depend on the tile decompostion of the domain).
893    o pkg/seaice: change a discretization detail to make the B-grid code
894      "more symmetric". This change is likely to remove all "ridges/leads" that
895      where quasi-aligned with the grid in B-grid solutions. It may also be
896      the solution to the stress coupling issues with the B-grid.
897    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
898      remove .cvsignore from input dir. (since testreport no longer run here).
899    o pkg/thsice:
900     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
901     - fix reshaping of sea-ice just after advection:
902       melt all the ice only if ice-volume is too small.
903     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
904       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
905     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
906    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
907      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
908    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
909      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
910      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
911      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
912      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
913      -> update output.txt
914    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
915     this affects truncation error: -> update output.txt of exp:
916      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
917      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
918    
919    checkpoint59f
920    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
921    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
922      a bounded range (in forward mode)
923    o pkg/ecco, ctrl, autodiff and mom_common:
924     internal parameter controls, completements of implementations
925    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
926    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
927      (not seem any difference in testing results).
928    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
929       at face corners.
930    o pkg/generic_advdiff:
931     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
932      loop range indices for computing vertical advection tendency
933      and do the calculation in the interior only (no overlap) ;
934      for now, only implemented for SOM advection (to save CPU time).
935     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
936    o exch2 adjoint
937      First set of changes:
938      - add exch2 hand-written adjoint templates
939      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
940        This will require cleanup in pkg/autodiff/*.F
941        (changed routines currently kept separate in verif. code/)
942      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
943        that used to hide exch2 or cubed-sphere specific code
944        (commented via 'cph-exch2')
945    o pkg/seaice
946      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
947    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
948       output of global_ocean.cs32x15.thsice .
949    
950    checkpoint59e
951    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
952      for B-grid vector (not yet tested) and C-grid vector (<- only used
953      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
954    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
955      (#ifdef ALLOW_SALT_PLUME)
956    o gather_2d/scatter_2d: removed halo regions
957    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
958      scheme and the corresponding test case (under front_relax dir). For now,
959      only available with Skew-flux form and not yet tested in realistic set-up.
960      adjoint: store directives updated, but gradient checks deteriorated,
961      so maybe GM/Redi adjoint is now broken.
962    o seaice adjoint
963      * add AREA, HEFF, HSNOW as control variable
964        (should not change lab_sea results)
965      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
966    o pkg/seaice:
967      * added computation of saltFlux in seaice_growth;
968        For time being, sea ice salinity is assumed constant
969        contribution of snow flooding to freshening of sea ice is neglected.
970        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
971        defaults to 0.0 in order to maintain backward compatibility.
972        Typical values for SEAICE_salinity are 4 to 10 g/kg.
973      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
974      * added SEAICE_availHeatFrac, which specifies fraction of surface level
975        heat content used to melt or grow ice
976      * commented out cap of HICE: it helps keep ice thinner
977      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
978      * applied OBCS T/S mask to HEFFM sea ice mask
979    
980    checkpoint59d
981    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
982     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
983     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
984    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
985     and change default value of parameter "GM_Small_Number";
986     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
987       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
988       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
989    o pkg/ecco: cost function when applying pkg/smooth to controls
990    o pkg/ctrl: add forcingPrecond run time parameter
991    o pkg/seaice:
992     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
993     - fix bug in metric terms of u-equation in LSR solver (implicit part),
994       changes verification/lab_sea
995     - rearrange implicit part of u-equation in LSR solver to make it easier to
996       read, understand, and debug. This causes changes at the truncation level.
997     - fix (serious) bug in the boundary conditions (sign error in the implicit
998       part) of the LSR solver. Changes all LSR results.
999     - fixed problem with HSNOW initialization to avoid thick snow when AREA
1000       is initilized with small values - does not change lab_sea results.
1001     - added HsnowFile initialization capability
1002    o pkg/smooth: addition to model/src and pkg/ctrl so allow
1003     initialization of pkg/smooth and application to control vector
1004    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
1005    o dependencies: pkg/profiles requires pkg/cal
1006    o pkg/profiles:
1007     - added option ALLOW_PROFILES_GENERICGRID
1008         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
1009         that interpolation information (grid points and coefficients) is provided
1010         within the netcdf input files.
1011         -> sample matlab scripts can be found in MITgcm_contrib/gael
1012         that allow you to prepare netcdf input files.
1013     - also modified: cleaner include statements, cleaner error print statements,
1014       cleaner stops when error, and more tests of the netcdf input files consistency.
1015    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
1016    o pkg/seaice:
1017     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
1018       requires a new routine: seaice_diagnostics_fill.F
1019     - make sure that seaice does not move if not forced (pressure replacement
1020       method, Hibler and Ip, 1995), changes results
1021     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1022     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1023       It is turned off by default (=-1.), because it changes the results.
1024     - make it possible to read AREA from a file, too.
1025    
1026    checkpoint59c
1027    o add S/R and diagnostics for oceanic mixed-layer depth
1028    o move GMRedi call after all vertical mixing schemes (including KPP)
1029    o pkg/thsice:
1030     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1031      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1032    o pkg/obcs:
1033     - bug fix for balance code
1034    o pkg/seaice:
1035      - allow values of SEAICE_elasticParm > 1
1036      - add new parameter SEAICE_evpTauRelax as an alternative
1037        to SEAICE_elasticParm
1038      - make lsr boundary conditions free slip (by default), changes result
1039      - add code for no slip boundary conditions for lsr
1040      - set minimum of zeta to zero (and not 4e8) (changes results)
1041      - add a cap on AREA after advecting AREA if seaice_growth is not called
1042    o change calculation of Visbeck K:
1043      - no longer depend on tapering scheme; instead, compute slope (limited
1044        by GM_maxSlope). this is equivalent to what was comuted before with
1045        clipping or linear tappering.
1046      - fix vertical averaging (wrong by 1/2 level)
1047      - leave the old version (but will not be maintained) within
1048        #ifdef OLD_VISBECK_CALC / #endif
1049      - update output of exp. ideal_2D_oce
1050    o change error catch in calc_r_star to improve vectorization
1051    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1052      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1053    o adjoint:
1054      Re-organized adjoint checkpointing according to Matt Mazloff
1055      (but with modifs/completions/cleanups)
1056      Storing is now bundled into large arrays to optimized I/O
1057      (and second step in cleanup of the_main_loop)
1058    
1059    checkpoint59b
1060    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1061      - export/import (between ocean & coupler) fields needed for ocean DIC.
1062    o pkg/seaice:
1063      - get rid of three more exchanges seaice_calc_viscosities (required
1064        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1065      - bug fix in seaice_ocean_stress (update of lab_sea required)
1066      - reduce loop boundaries to necessary minimum also in seaice_evp
1067      - go back to the old way of computing deltaC/Z as the adjoint likes that
1068        better
1069    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1070      passive tracer to an Age Tracer) + update output.txt
1071    o pkg/exf:
1072      - implement A-grid / C-grid selection for wind-stress input files.
1073      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1074      for now, in exf_bulk_largeyeager04.F only :
1075      - change implementation for case where windspeed + 2. components wind-stress
1076        are read-in. AND use rhoConstFresh to convert evap.
1077    o pkg/seaice:
1078      - use correct EXCH_UV for wind-forcing (on A-grid).
1079      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1080        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1081    o pkg/exf:
1082      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1083      EXF_INTERPOLATION:
1084      - merge global_with_exf/code version of exf_interp_read.F
1085        to the main code ;
1086      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1087        reading the file ; Important: This options needs to be defined to recover
1088        previous code.
1089        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1090      - no longer loose real*8 precision along the way when using exf_iprec=64.
1091    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1092      - change discretisation of evp-solver in order to avoid another exchange
1093        (changes lab_sea) and clean up a little
1094      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1095        help the adjoint (this also changes the results slightly)
1096      - add a few "_d 0" where they had been missing in seaice_evp.F
1097      - cleaning up: remove unused seaice_calc_rhs.F
1098    o pkg/exf: some cleaning-up:
1099      - change various "constants" into runtime parameters
1100      - cleaned-up Large&Yeager04 routine which should eventually
1101        replace exf_bulkformulae.F (changed names of S/R and CPP)
1102        and merged various ALLOW_ATM_WIND options
1103     only used with thsice pkg (in thsice_get_exf.F):
1104      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1105        which are used when useStabilityFct_overIce=TRUE (= the default)
1106      - change default values of ice & snow emissivity and scale downward LW
1107        by ice & snow emissivity.
1108    o pkg/thsice:
1109     fix few little problems, in thsice_calc_thickn.F:
1110      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1111      - melt only laterally if hIce < hThinIce (as the comments say)
1112      and in thsice_extend.F:
1113      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1114      - start to form ice as soon as the minimum ice-volume is reachable.
1115     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1116      and cpl_aim+ocn
1117    o pkg/kpp
1118     - move computation of surface related input fields to KPP into a new
1119       subroutine kpp_forcing_surf.F
1120     - remove wrong (within bi,bj loops) EXCH calls.
1121     - little cleaning (add argument myThid in last position, cvs header ...)
1122     - for now, fix conservation problem by exchanging KPPviscAz (may not
1123       be the best fix)
1124    o pkg/seaice
1125     - check for inconsistent evp parameter/cpp-flag combination
1126     - remove leftover errIO flat for obsolete name list error handling
1127    o OpenAD
1128     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1129    
1130    checkpoint59a
1131    o pkg/seaice: some parameter clarifications and a little bit of clean up
1132    o pkg/thsice: rename run-time parameters:
1133       himin       -> hIceMin
1134       himin0      -> hThinIce
1135       hihig       -> hThickIce
1136       i0          -> i0swFrac
1137       transCoef   -> bMeltCoef
1138       frac_energy -> fracMelting
1139      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1140       with default values (for now) that do not change the results.
1141      remove old version of thsice vars advection in pkg/seaice.
1142    o in FFIELDS.h:
1143      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1144      - make pLoad & sIceLoad always available (but still only used if
1145         ATMOSPHERIC_LOADING is #define).
1146    o pkg/kpp: replaced _KPP_RL with _RL
1147    o bug fixes for vertical diffusivity computations when both KPP and
1148        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1149        are no longer updating the vertical diffusivity array
1150        (passed as argument) but are (re-) setting those arrays.
1151    o pkg/seaice: fix bug in evp solver, while doing that
1152      - change (improve?) discretization of stress computations for both
1153        cgrid-lsr and evp solver
1154      - add a new routine to compute strain rates
1155      - the above changes lab_sea results
1156      - add no slip conditions for evp solver (off by default), lsr-version
1157        may follow
1158      - fix exchange for shear at Z-points (does not change lab_sea)
1159      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1160        (to force the user to pick a time step since there is not "safe" way
1161        of choosing it)
1162      - add principal stress diagnostics
1163      - rearrange fields for evp a little to avoid having to call a: too many
1164        exchanges and b: exchanges for stress trensor components which we do
1165        not have.
1166      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1167        of evp, complete rewrite for lsr case (latter is does not yet work
1168        in all cases)
1169    o pkg/kpp: add code to have mixing in shelf ice caverns
1170      - add myThid to all kpp routines (long overdue)
1171    
1172    checkpoint59
1173    o pkg/exf:
1174      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1175        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1176      - move exf header files from lower_case.h to UPPER_CASE.h ;
1177        add missing cvs Header & Name
1178      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1179      - add namelist param. selectStressGridPosition, exf_monFreq
1180      - retire many _CLIM routines, and remove data.exf_clim
1181        + params moved to data.exf
1182        + climsst, climsss now handled by exf_set_gen, i.e.
1183          climss?period=0 refers to constant field,
1184          climss?period=-12 to monthly forcing
1185      - split up namelists in data.exf
1186    o pkg/seaice:
1187      - remove seaice_exch and seaice_exch_uv
1188      - remove superfluous exchange of theta
1189      - add myThid to seaice_budget_ocean/ice
1190      - add new interface for atmospheric wind forcing (C-grid only)
1191        + new routine
1192        + two new field (taux, tauy for stress over ice)
1193        + removed one global field (DAIRN) for C-grid case only
1194    o pkg/thsise
1195      - 2nd set of modifs for thsice adjoint in conjunction with exf
1196    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1197    
1198    checkpoint58y_post
1199    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1200      vertical diffusivity, similar to that in MOM4; turned on using
1201      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1202      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1203    o Added capability for 3D specification of background vertical diffusion
1204      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1205      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1206      "data" file that contains the 3D vertical diffusivity coefficients.
1207    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1208      - add code within pkg thsice to advect & diffuse sea-ice fields
1209      similar to (and will replace) what has been added in  seaice_advdiff.F,
1210      but: - conserving Mass, Heat & Salt.
1211           - better when using non-linear advection scheme (not yet fully tested)
1212           - can also be used in atmospheric set-up (for now, only the diffusion).
1213    
1214    checkpoint58x_post
1215    o IO option for global-file compact format:
1216      - add options when generating topology (utils/exch2/matlab-topology-generator)
1217      - add I/O capability (pkg/mdsio).
1218      - adapt utils/matlab/rdmds.m to read this format.
1219      for now long-line format not yet supported by pkg/mdsio (& exch2).
1220    o shelfice: add a few diagnostics
1221    
1222    checkpoint58w_post
1223    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1224      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1225      (and replace horiVertRatio in NH code).
1226      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1227                         and tutorial_plume_on_slope (sensitive to truncation)
1228    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1229      directly to drive seaice model (C-grid only)
1230    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1231     - reintroduce computation of wind from stress,
1232     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1233       mass points to avoid tau = 0
1234     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1235    o rdmnc.m: make it work with "global" files created with gluemnc
1236    o rdmnc.m : some improvements in dealing with singleton dimension
1237      (tested on all testreport mnc output files).
1238    o genmake2: disable pkg/profiles if netcdf test fails.
1239    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1240    o move call to cal_readparms up to make calendar parameters/variable available
1241      to all packages
1242    
1243    checkpoint58v_post
1244    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1245      useDynP_inEos_Zc tested.
1246    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1247    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1248      and portions thereof.  See read_cs.txt for description and examples.
1249    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1250      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1251      following the great-circle arc between those 2 points.
1252    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1253      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1254    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1255     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1256     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1257     - still needs work (not working with some options ; efficiency to improve)
1258       and serious testing.
1259     - use this scheme for temperature & salinity in 2 advection test exp.:
1260       advect_xy & advect_xz, respectively.
1261    
1262    checkpoint58u_post
1263    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1264    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1265    o testreport: add option "-skipdir" to skip some test.
1266    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1267      momentum calculation.
1268    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1269    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1270      remove checkpoint.F and the_correction_step.F (no longer used);
1271      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1272    o add option (linFSConserveTr) to correct for tracer source/sink due to
1273      Linear Free surface
1274    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1275    o pkg/thsice: fix reading mnc-pickups
1276    
1277    checkpoint58t_post
1278    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1279    o pkg/mdsio:
1280     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1281       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1282       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1283     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1284     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1285       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1286     - new S/R (to replace MDSWRITEMETA), which allows to write more
1287       informations (variable names, time ...) to meta files.
1288     - modify rdmds.m to give back the meta file content.
1289    o pkg/diagnostics: change vertical interpolation to be safer, and more
1290       flexible (define p-levels to interpolate to in data.diagnostics);
1291      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1292       diagnostic pointer.
1293    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1294    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1295    o fix multi-category seaice:
1296     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1297       SEAICE_MULTICATEGORY
1298     - fix short wave heat flux
1299    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1300       and allow to use EVP solver. Change forward lab_sea: test both EVP
1301       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1302    o Initial check-in of lab_sea adjoint
1303      (very similar to natl_box_adjoint/code_seaice)
1304      * used C-grid and EVP solver
1305      * used KPP, GM/Redi
1306      * uses inAdExact=.TRUE.
1307      * gradient checks fail for both ADM and TLM
1308        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1309        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1310        issue is related to forward mismatch between g77 an ifort
1311    o pkg/seaice: overhaul of thermodynamics
1312     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1313     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1314     - move a few global fields out of SEAICE.h into seaice_growth.F and
1315       make them 2D (FICE/QNETO/ ...)
1316     - remove FO (it is the same as QNETO)
1317     - introduce a few local fields to avoid modifying external fields such
1318       as atemp, etc.
1319    
1320    checkpoint58s_post
1321    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1322      changed exf_set_gen.F so that
1323        genperiod=0 means input file is one time-constant field and
1324        genperiod=-12 means input file contains 12 monthly means
1325    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1326      this affects truncation error ; generate new output file for exp. which
1327      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1328        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1329        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1330        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1331        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1332        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1333    o start implementation of deep-atmosphere and anelastic formulation
1334    o verification: remove 2nd copy of input files and use script "prepare_run"
1335      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1336    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1337    o profiles: fix for multithreaded case
1338    
1339    o diagnostics: rename few diags:
1340      s/'PRESSURE'/'RCENTER '/g
1341      s/'TICE    '/'oceFreez'/g
1342      s/'TAUX    '/'oceTAUX '/g
1343      s/'TAUY    '/'oceTAUY '/g
1344      s/'SWFLUX  '/'oceQsw  '/g
1345      s/DIFx/DFxE/g
1346      s/DIFy/DFyE/g
1347      and add few ocean-forcing diagnostics:
1348      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1349    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1350      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1351      as actual snow thickness.  It now refers everywhere to effective snow
1352      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1353    
1354    checkpoint58r_post
1355    o modifications to pkg/seaice/growth.F, which change results of
1356      lab_sea experiment: fixes pertain to melting snow over open water, to
1357      masking EVAP under sea ice, and to using the correct AREA variable for
1358      computations of EVAP, PRECIP, HSNOW, and GHEFF
1359    o add ability to read bathy, salt, and theta using MNC (off by def)
1360    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1361      both are turned off by default and do no change any results
1362    o seaice advection with pkg/thsice: a step toward the use of non-linear
1363      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1364    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1365      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1366      in natl_box (affects results @ truncation level: update output.txt)
1367    o multi-threading and IO:
1368      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1369      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1370        (needed to work with SingleCpuIO): tested in all verif. exp.
1371    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1372      affects the results (but none of the verification test uses this scheme).
1373    o Adding some pkg/diagnostics capability to pkg/seaice
1374      (will certainly be subject to changes)
1375    o ctrl: adding new control variables:
1376      lwflux, lwdown, evap, snowprecip, apressure, runoff
1377    
1378    checkpoint58q_post
1379    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1380      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1381      high_res_cube configuration by 4% on Columbia.
1382    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1383      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1384      dynamical allocation (seems to work in multi-threaded).
1385    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1386      single CPU io) so that TAF does not have to see EESUPPORT.h
1387    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1388    
1389    checkpoint58p_post
1390    o obcs: stop if obcs is used with useCDscheme = .true.
1391    o shelfice:
1392     - fix a sign error so that no slip at shelfice interface works
1393     - remove stop for combination non-hydrostatic code and shelfice. That does
1394       not mean, that the results are correct, but at least they are numerically
1395       stable
1396    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1397    o added adjoint exch routined for all exch*3d* routines
1398      and updated flow directives
1399    
1400    checkpoint58o_post
1401    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1402      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1403    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1404      and clean-up reading/writing of pickup files.
1405    o fix local version of read/write pickup (NH part) in rotating_tank/code
1406    o simplify EXCH interface:
1407     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1408     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1409    o added the regrid package
1410    o shelfice:
1411     - add a simple boundary layer scheme to reduce noise
1412     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1413    
1414    checkpoint58n_post
1415    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1416       local variable (not in common block).
1417    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1418      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1419      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1420        to work with SingleCpuIO.
1421    o add "_d 0" to real constant of pkg/cfc subroutines ;
1422       update exp. cfc_exemple & tutorial_cfc_offline output files.
1423    o multi-threading and IO:
1424      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1425        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1426      - barrier before and after reading.
1427      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1428      - avoid using MDS_WRITELOCAL for LAND pkg output.
1429      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1430        common-block variables ; Allows multi-threading with master-thread IO.
1431    o change default MAX_NO_THREADS from 32 to 4 ;
1432      and stop cleanly when MAX_NO_THREADS is too small.
1433    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1434    
1435    checkpoint58m_post
1436    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1437       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1438    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1439       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1440       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1441    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1442        add MITgcm_tutorials (= code + all the tutorials)
1443    o ecco, option to compute cost for total ssh (mean+anom)
1444    o consistent with addition of ptracer and ssh in pkg/profiles
1445    o profiles: adding ptracer and ssh
1446    o testreport: change multi-test output-file name
1447      (from output.txt.{name} to output.{name}.txt)
1448    o profiles: now ok for mutli-tiles case
1449    o seaice: add 4 parameters for different advection schemes for area,
1450      (effective) seaice thickness, enthalphy, and snow height. Their default
1451      is the standard parameter SEAICEadvScheme
1452    o calc_gw:
1453     - add cosFacU in zonal viscous flux (harmonic.visc.).
1454     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1455       of tutorial_plume_on_slope.
1456    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1457    o calc_gw: true flux-form, account for horizontal grid spacing.
1458      update rotating_tank results, but not plume_on_slope (affected at
1459      truncation level, 11 digits).
1460    
1461    checkpoint58l_post
1462    o calc_gw:
1463     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1464     - remove side-drag for now (need to fix it); update plume_on_slope results.
1465     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1466    o commit code to make SST/SSS weights spatially variable
1467      (based on either variable in-situ or variable initial T/S weights)
1468    o pkg/ecco:
1469      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1470        now based on horizontally varying weights wthetaLev, wsaltLev
1471      * cost_averagesflags now returns year indices in addition to day, month
1472      * sflux balance is performed on annual basis
1473        (sflxumm, sfluxmm2, bal_sfluxmm)
1474      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1475        including separate counting and multipliers
1476    o pkg/rbcs
1477      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1478    
1479    checkpoint58k_post
1480    o testreport:
1481     - always build in dir. "build" (if not there, mkdir build instead of building
1482       & running in input)
1483     - run in dir run (if it exists), in build otherwise.
1484     - call prepare_run (if input/prepare_run exists)
1485     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1486    o pkg/exf modifications to interpolation and rotation routines for more
1487       reasonable treatment of North Pole singularity: for tracers North Pole
1488       value is set to northernmost zonal-mean value, for zonal velocity it is
1489       set to zero, and for meridional velocity it is set to northernmost value.
1490    o pkg/exf/exf_check_range.F
1491     - add tile index to diagnostics and move stop statement to the very
1492       end of the routine.
1493    o pkg/diagnostics: (diagnostics_main_init.F)
1494      define title of isomorphic variables according to the current config.
1495    o pkg/thsice with pkg/seaice dynamics:
1496    - fix domain of computation (interior only, required for exf) and do exchanges
1497    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1498    o towards a standard way of dealing with multi-threading in MONITOR
1499      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1500    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1501       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1502    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1503    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1504    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1505       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1506    o tracer advection:
1507     - clean-up and simplify calc_common_factors.F
1508     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1509       advection subroutine (but still not used within DST advection S/R)
1510    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1511    
1512    checkpoint58j_post
1513    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1514      from file (collects calls previously in FORWARD_STEP)
1515    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1516    o adjoint store dir. adjusted accordingly
1517    o genmake2
1518      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1519    
1520    checkpoint58i_post
1521    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1522      on wind stress (SEAICEstressFactor defaults to 1.)
1523    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1524      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1525    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1526      on CS-grid: no longer loosing mass.
1527    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1528    o pkg/ggl90: fix sloppy output and fix a bug
1529    o pkg/seaice: added SEAICEuseEVPpickup parameter
1530      - Set to false in order to start EVP solver with
1531        non-EVP pickup files when using SEAICEuseEVP
1532      - fix sign error in diffusion in seaice_calc_rhs
1533    
1534    checkpoint58h_post
1535    * Modifications for bottom topography control
1536      o replace hFacC by _hFacC at various places
1537      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1538      o add non-self-adjoint cg2d_nsa
1539      o update autodiff support routines
1540      o re-initialise hfac after ctrl_depth_ini
1541      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1542    * Adding verification for 5x5 box (4-layer) bottom topography control
1543    
1544    checkpoint58g_post
1545    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1546       used for mean seasonal cycle, mean diurnal cycle); add an example
1547       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1548    o pkg/ggl90:
1549      - add parameter (minimum surface kinetic energy)
1550      - fix bug (avoiding division by zero)
1551    o couple pkg/thsice to pkg/seaice:
1552      - modify advection in seaice to accomodate new scalar fields to be advected
1553      - only muliDimAdection scheme work with seaice/thsice
1554      - mapping of thsice-variables to seaice-variables, back and forth
1555      - does not break the verification experiments, but does not give the
1556        desired results either
1557    o pkg/seaice
1558      - make (default) second order advection a bit less confusing?
1559    
1560    checkpoint58f_post
1561    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1562      to pkg/seaice):
1563      - new routines thsice_map_exf and thsice_get_exf provide the interface
1564      - add an additional formal parameter to thsice_solve4temp
1565    o pkg/exf:
1566      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1567      - correct Stefan-Boltzmann constant
1568      - new parameter for longwave surface emittance
1569      - separate some stuff from exf_bulkformulae into new routines  
1570        exf_radiation, exf_wind
1571      - add new parameters and constants: longwave emissivity for ocean, ice
1572        and snow, evaporation parameters over ice
1573      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1574        either wind from stress or stress from wind
1575    o pkg/thSIce:
1576    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1577    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1578       and THSICE_CALC_THICKN
1579    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1580    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1581      to make debugging easier.
1582    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1583    o pkg/bulk_force:
1584      - clean-up comments and parameters ;
1585      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1586    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1587      generate new output for test-experiment: aim.5l_cs.thSI
1588    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1589      testreport accordingly
1590    
1591    checkpoint58e_post
1592    o SEAICE_CGRID adjoint done
1593    o R_STAR adjoint implemented.
1594      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1595      * need to sort out init. of h0facc, etc.
1596    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1597      to be able to use it in pure forward.
1598    
1599    checkpoint58d_post
1600    o upgrade simple test-experiment to tutorial example:
1601     step.1: duplicate the experiment and (step.2) will remove the old copy.
1602      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1603      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1604      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1605      tutorial_global_oce_biogeo    <- copy of dic_example
1606      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1607      tutorial_plume_on_slope       <- copy of plume_on_slope
1608      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1609      tutorial_global_oce_optim     <- empty for now (David ?)
1610      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1611     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1612    o correct a sign problem in cost_scat.F
1613    o obcs and ptracers: fix boundary conditions for advections schemes
1614      with larger stencil
1615    o thsice adjoint: start
1616    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1617      completeness
1618    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1619      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1620    o ptracers adjoint:
1621      * avoid extensive recomputatations
1622      * fix missing re-init. of gptr (missed by TAF)
1623    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1624      me to turn off the excessive output to STDOUT that this package produces
1625    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1626      and add those terms in Vector-Invariant formulation.
1627    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1628      if the control period (xx_hfluxperiod etc) is 0
1629    o in profiles pkg, clean routines and fix details
1630    o in ecco pkg, reading ssh data:
1631      fix problem in case the model does not start at iter0=0
1632    o fix mnc-pickup/restart for ptracers
1633    o new package prifiles:
1634      code to compute profile-based cost by Gael Forget
1635      (modifs in ecco, ctrl, autodiff)
1636    o Benign bug fix in initialization (spotted by M. Mazloff) of
1637      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1638    
1639    checkpoint58c_post
1640    o adjoint: finish NLFS adjoint and provide reference output in
1641      verification/global_ocean.90x40x15/results_ad_nlfs
1642    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1643      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1644      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1645      with SEAICE_CGRID defined.
1646    o move calendarDumps from "data" to "data.cal" and clean-up the code
1647      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1648    o add useEXF & useCAL flags (for now, set in hard-coded way)
1649    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1650      (were missing in NH mode, and wrong in quasihydrostatic mode).
1651      waiting for Chris updated version of calc_gw to add those CALLs.
1652    o fix bug in quasihydrostatic S/R ;
1653      add a test for this option: global_ocean.90x40x15.qshyd
1654    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1655      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1656    o add on/off flag useOffLine for package OFFLINE
1657    o seaice:
1658      - modify advection so that it works also on the C-grid
1659      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1660        problem in multi-tile runs with C-grid
1661      - add flags for clipping ice velocities and/or masking solver forcing
1662      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1663        C-grid solver
1664      - added a few comments to seaice_diffusion.F
1665      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1666        are now exclusive)
1667      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1668        required re-ordering the code a little:
1669       + make DAIRN global variable (defined in SEAICE)
1670       + move computation of the viscosities eta and zeta into a new separate
1671         routine (because I need to recompute them in seaice_ocean_stress.F)
1672    
1673    checkpoint58b_post
1674    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1675      update output.txt of exp. aim.5l_cs.thSI
1676    o various mnc cleanups and improvements:
1677      + shrink lookup tables by factor of ~4
1678      + better error reporting when running out of lookup space
1679      + able to handle longer path/file names (up to 500 chars)
1680    o adjoint:
1681      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1682      - TBD: "hidden" mom_vecinv recomp. in dynamics
1683    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1684     (allow to differentiate between forcing components using new integer flags:
1685      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1686     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1687    o ecco
1688      - enable trend removal from SSH anomaly obs.
1689    o adjoint
1690      - a fix for PmEpR when #undef EXACT_CONSERV
1691      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1692      - try to fix "hidden" recomp. in forward_step for NLFS
1693        (NLFS seems broken sometimes after I checked it in)
1694    o seaice:
1695     - add c-grid version of the dynamic solver:
1696       + three new routines that are the c-grid substitute lsr, dynsolver
1697         and ostres
1698       + put a few fields that were local to dynsolver into global common
1699         blocks, so that I can move the computation of stresses etc into
1700         seaice_lsr (saves coding but may break the adjoint).
1701     - replace more hardwired parameters by runtime parameters
1702     - add ice masks that mask the rhs of the implicit solvers where there
1703       is no ice (commented out in seaice_dynsolver, because i am not sure
1704       if this works properly), eventually this should replace the clipping
1705       of ice velocities in seaice_dynsolver to +/-40cm/s.
1706    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1707      include it only where its needed
1708    o move balancing of fluxes before the call of external_forcing_surf
1709    o seaice:
1710      - correct units of turning angles (now they are really in degrees)
1711      - move computation of GWATX/Y out of main routine into dynsolver
1712      - initialize GWATX/Y in seaice_init
1713    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1714      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1715    o seaice: add runtime flags for turning angles (default to zero)
1716    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1717      and trend from exf forcing and ctrl control adjustments
1718    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1719      (since checkpoint57x_post)
1720    o change the default rotation period to 86164.s = the Earth rotation
1721    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1722      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1723    o seaice advection: add code for choosing between the default (2nd order
1724      central differences) and multiDim advection schemes provided by
1725      pkg/generic_advdiff
1726    o seaice:
1727      - removed all references to SEAICE_GRID.h fields from
1728        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1729        (cubed-sphere configuration will change a little)
1730      - grid computations in seaice_init are obsolete now.
1731      - cleaned up code a little so that is easier to read (hopefully).
1732      - added new (better?) discretizations of default advection and diffusion
1733        (turn on with SEAICEuseFluxForm)
1734      - replace 1 in 3d global fields by kSurface in growth.F
1735      
1736    checkpoint58a_post
1737    o seaice:
1738      - bug fix in advect.F
1739    o shelfice:
1740      - separate shelfice load anomaly from pload (breaks with time
1741        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1742        Its default is 0., but it may be computed more cleverly from (unknown)
1743        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1744        done offline. A good approximation of the pressure load anomaly is
1745        necessary to avoid large initial adjustment processes underneath
1746        deep-reaching shelfice.
1747      - small fix in ISOMIP shelfice_thermodynamics
1748      - add more sophisticated thermodynamics of Hellmer (1989), this is
1749        now the default
1750      - give a few constants more intuitive names
1751    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1752      if bulk formulae are used in long integration (especially EmPmR). Turn
1753      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1754      if balancePrintMean, the imbalance that is substracted is printed to
1755      STDOUT.
1756    o fix bug (typo) in obcs_apply_eta.F
1757    o add a new package shelfice which enables us to model the circulation
1758      underneath shelf-ice with draughts of hundreds of meters.
1759     - works
1760     - to do: + include improved thermodynamics
1761              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1762                instead of new field kTopC
1763              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1764                instead of new field R_shelfIce and new code in ini_depth.F
1765                and ini_mask_etc.F?
1766              + adjust vertical mixing schemes?
1767    o seaice pkg:
1768     - add a cpp-flag to include a simple formula for a salinity dependent
1769       freezing point of sea water at the surface
1770     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1771       meridional stresses are now different (and hopefully correct)
1772    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1773       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1774       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1775    o pkg/diagnostics: add options and parameters for regional-statistics
1776       diagnostics ; define regions by reading a region-mask from a file
1777       (might add other options later)
1778    o pkg/bulk_force:
1779     - add option and parameters to use AIM surface-flux formulae.
1780     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1781       others forcing fields (defined in PARM05, parameter file "data") are loaded
1782       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1783     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1784     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1785     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1786       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1787     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1788    
1789    checkpoint58
1790    o add "--embed-source" option to genmake2 which, when the supporting
1791      tools can be compiled (as determined by genmake2) will turn on the
1792      embed_files package which then embeds the entire MITgcm source code
1793      (*.[fFhc] + Makefile) used for the build within the executable
1794      - requested by CNH but off by default
1795      - adds a paltry <9MB to the mitgcmuv executable in most cases
1796      - only writes the output when useEMBEDSRC in eedata is true
1797    o clean up 3-dim. relaxation codes:
1798      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1799      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1800      * Thanks to Tom Haine for testing!
1801    
1802    checkpoint57z_post
1803    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1804      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1805    o fix the pickup behavior for obcs in combination with ptracers
1806    o fix a bug in ptracers_external_fields_load
1807    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1808      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1809    o transfered surface NH pressure to eta field (if exactConserv).
1810    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1811         and update lab_sea output.txt file.
1812    o completing 3-dim. relaxation code: additional term
1813         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1814      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1815      * At compile time, in "EXF_OPTIONS.h" set
1816          #define  ALLOW_CLIMTEMP_RELAXATION
1817          #define  ALLOW_CLIMSALT_RELAXATION
1818      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1819          tauThetaClimRelax3Dim = 15552000.0,
1820          tauSaltClimRelax3Dim  = 15552000.0,
1821      * 3 cases:
1822          1) Use a constant-in-time 3-dim. field
1823          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1824          3) Real-time relax. to time-evolving prescribed field
1825    o Adding Laplacian-type smoothness constraint on
1826      initial and boundary (forcing) controls (ic, bc)
1827      * enable at compile-time via
1828        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1829      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1830      * Absolute scale somewhat unclear so far
1831      * no area weighting was included since no other cost term does so far
1832    
1833    checkpoint57y_post
1834    First step for a NLFS adjoint
1835    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1836    o new init. routines for calc_r_star, calc_surf_dr
1837    o still need to deal with ini_masks_etc
1838    o testreport seemed happy
1839    checkpoint57y_pre
1840    
1841    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1842    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1843    o add new offset feature to offline pkg (plus minor cleanup)
1844    o cfc fixes for final year of integration
1845    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1846      be in GCHEM_OPTIONS).
1847    
1848    checkpoint57x_post
1849    o fix testreport Pb in multiple test experiment.
1850    o cleanup our namelist syntax in verification:
1851      - make it more F95 standards compliant (some work still needed)
1852      - allows the vast majority of our tests to work with gfortran
1853    o Non-Hydrostatic:
1854     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1855     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1856    o Allow to apply AB on T,S rather than on AB(gT,gS):
1857     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1858     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1859       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1860     - need a "clever" read_pickup to restart from the other AB formulation
1861    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1862    o remove some unused variables (reduces number of compiler warnings)
1863    o adjoint
1864      * Disable useVariableViscosity for adjoint for time being
1865        (there are a number of extensive recomputations)
1866      * Initialize certain variables needed for adjoint
1867    
1868    checkpoint57w_post
1869    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1870                 fix the singleCpuIO RS version of MDSWRITEFIELD
1871       and add a WARNING if using globalFiles=T with multi-processors.
1872    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1873      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1874    o tracer advection scheme:
1875      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1876       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1877       was not very convenient).
1878      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1879       (further tests needed for the implicit DST & Flux-Limiter schemes).
1880    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1881      and sRef for convenience, handy, when you want to initialize
1882      ptracers in a large domain with a constant non-zero value. Also,
1883      untangle ptracers_init.F a little.
1884    
1885    checkpoint57v_post
1886    o change dome exp. to use variable viscosity in side-drag terms.
1887    o remove all the files from the cfc_offline test since they are now
1888      incorporated into tutorial_cfc_offline which has been producing
1889      identical results for a few days of testing
1890    o add new parameter: sideDragFactor to enable half-slip-side BC
1891      and change side-drag S/R to use viscosity from mom_calc_visc
1892      (can switch back by setting sideDragFactor=0.); affects results at
1893      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1894       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1895    o vorticity & strain are now computed without masking, to account for
1896      no-slip-side BC in variable viscosity calculation ; mask is applied
1897      anyway later on, before computing advection/coriolis terms.
1898    o modify exp4 to test new obcs support for reading from external files
1899      and for passive tracers
1900    o fix behavior of ptracers_monitor when monitor output is written to a
1901      netcdf-file; still not independent of monitor.F (writes in the same
1902      file).
1903    o change default value of tRef (put a uniform, meaningful value for ocean
1904      & atmos) and initialize sRef (was missing, as Martin mentioned).
1905    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1906      to be proportional to enstrophy dissipation length.  Thus,
1907       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1908      This is now consistent with Smagorinsky and with the manual.
1909    
1910    checkpoint57u_post
1911    o OBCS and PTRACERS: add open boundary support for passive tracers
1912      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1913        OB-values from file; this is not different from the way theta and salinity
1914        are treated
1915      - however, Orlanski-radiation conditions are not supported, and the model
1916        will stop if you use pTracers and Orlanski at the same time.
1917      - beefed up the rountine obcs_external_fields_load: now only those open
1918        boundary values are overwritten with values from files for which there
1919        are really files, otherwise the OB-fields remain untouched. This makes
1920        it possible to use different OBs at different ends of the domain (as
1921        with EXF)
1922    o reduce number of exch calls in shap_filt (s2).
1923    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1924      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1925    
1926    checkpoint57t_post
1927    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1928    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1929      same truncation, independent of the face number: affects affects several
1930      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1931    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1932      note that biharmonic viscosity + no-slip was not tested in any experiment.
1933    o fix bug in non-linear free-surf side-drag ; generate new output for
1934      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1935    o make mnc honor the writeBinaryPrec flag for most kinds of output
1936    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1937    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1938      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1939    o add brackets in multi-terms sum to get same truncation, independent of
1940      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1941      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1942    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1943      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1944      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1945      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1946      Suggested values of viscosity parameters found in mom_calc_visc.
1947      Many new viscosity diagnostics available.
1948    
1949    checkpoint57s_post
1950    o Add clearing-house for viscosity calculations, mom_calc_visc and
1951      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1952      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1953      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1954      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1955      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1956      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1957      ViscAhStrain and viscAhTension are now retired.
1958    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1959    o In response to JMC's bug report, genmake2 now ignores any soft-links
1960      that it finds in the *current* directory when searching for files.
1961      Soft-links found in any other source directories will still work as
1962      they did before.
1963    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1964      a C routine to unlimit the stack size
1965    o mnc-ify pkg/aim snapshot vars
1966    o mnc-ify pkg/land as requested by Daniel
1967    o various changes to mnc including:
1968      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1969      - output can now be grouped so that all files within a group
1970          change the ITER portion of their names in lock-step together
1971      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1972          and works with both EXCH1 and EXCH2 (but needs more testing)
1973      - writing works for all verification test cases w/ g77 on Linux
1974    
1975    checkpoint57r_post
1976    o make MNC variable initialization happen earlier
1977    o add diagnostics for (almost) each term of the momentum Eq.
1978    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1979    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1980    o remove MINIMAL_TAVE_OUTPUT option ;
1981      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1982    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1983      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1984    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1985    o add time-dependent SST, SSS control
1986    o cost terms in ecco/ modularized (new cost_generic.F)
1987    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1988    o new infrastructure for seaice model vs. obs misfits in seaice/
1989      * driver from the_main_loop.F is seaice_cost_driver.F
1990      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1991      * gradient check in Exp. 6a of natl_box_adjoint/
1992    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1993      (see README file)
1994    
1995    checkpoint57q_post
1996    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1997    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1998      - bug was reported by Jean-Michel and Ian Fenty
1999    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
2000      update exp. cpl_aim+ocn output.
2001    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
2002      Needed for high-res. runs with large global files
2003      to be able to limit tapelev size
2004    o Changed some tests for adjoint:
2005      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
2006      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
2007      * global_ocean.90x40x15/ back to default 3-level checkpointing
2008    o Modifications to enable scripted COMMON to MODULE conversion
2009      * verification/OpenAD/code/ has necessary scripts and description;
2010      * converts, compiles and runs successfully;
2011    
2012    checkpoint57p_post
2013    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
2014    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
2015      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
2016    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
2017    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
2018      (was already the case for dissipation with mom_vecinv,
2019       and also the case for grad.PhiHyd when staggered-timeStep)
2020      This will allow to put dissipation out-off the AB time-stepping.
2021     Unfortunately, affects truncation error. Update output of exp. that "fails"
2022      (cg2d matching number) and leave the others for later: front_relax(10),
2023      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
2024      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
2025    
2026    checkpoint57o_post
2027    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
2028      (2) its ready to be documented during the 20050801 DocFest
2029    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
2030      for ideal_2D_oce and lab_sea on linux_ia32_g77
2031    o set to #undef CTRL_SET_OLD_MAXCVARS_30
2032      in global1x1_tot/code_seaice_adj to access indices 32, 33
2033      (worth another tag)
2034    
2035    checkpoint57n_post
2036    o adding precip control xx_precip 32
2037    o adding swflux control xx_swflux 33
2038    o Replacing 10 forcing penalty cost routines by 1 generic.
2039    o Implementing partitioning in time-mean and variable adjustment
2040      for atmos. state.
2041    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
2042  o in natl_box_adjoint:  o in natl_box_adjoint:
2043    * updated: results_bulk/    * updated exp 1 to 10
2044    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
2045    o updated global1x1/*_seaice_adj/
2046      to incorporate latest changes
2047    o enable useSingleCpuIO for mdsio vector routines
2048      (applies in particular to tapelev I/O)
2049    o removed inefficient K-loop in all active_file*control*.F
2050    
2051  checkpoint57m_post  checkpoint57m_post
2052  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
