6    
7    checkpoint57n_post
8    o adding precip control xx_precip 32
9    o adding swflux control xx_swflux 33
10    o Replacing 10 forcing penalty cost routines by 1 generic.
11    o Implementing partitioning in time-mean and variable adjustment
12      for atmos. state.
13    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
14    o in natl_box_adjoint:
15      * updated exp 1 to 10
16        (but does not have time-mean vs. variable split results yet)
17    o updated global1x1/*_seaice_adj/
18      to incorporate latest changes
19    o enable useSingleCpuIO for mdsio vector routines
20      (applies in particular to tapelev I/O)
21    o removed inefficient K-loop in all active_file*control*.F
22    
23    checkpoint57m_post
24    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
25      and advect_cs (use EXCH-2 and standard cs-32 grid files).
26    o pkg/exch2: filling of face-corner halo regions is optional
27      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
28    
29    checkpoint57l_post
30     tag before updating tutorials (pre-release-2)
31    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
32       for output and interpolation of input fields onto model grid)
33    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
34       Affects results of exp. rotating_tank ; update output.txt.
35    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
36          and taking the square quantity and/or using a fraction-weight field.
37    o fix aim_diagnostics_init.F mate numbers.
38    o add mnc output capability to diagnostics/diagstat and update
39      our cvsignore files for the ACSII output generated
40    
41    checkpoint57k_post
42    o lab_sea now uses diagnostics package and provides a suite of
43      new EXF diagnostics output.
44    
45    checkpoint57j_post
46    o exf
47      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
48        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
49        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
50      * extended diagnostics output
51        - now includes all EXF variables
52        - hs, hl moved to common block
53        - separate S/R for diagnostics, called after ctrl vector is added
54        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
55        - EXFqnet contains true Qnet (i.e. includes qsw)
56      * updated verif. lab_sea, global_with_exf
57      * Rearranging hflux (exf_mapfields -> exf_getforcing)
58        to ensure that diagnostics sees a true EXFqnet
59    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
60    o diagnostics pkg: change pointers so that 1 diagnostic can be used
61      several times with different frequencies.
62    o mnc-ify the thsice package as requested by Daniel Enderton
63      - the monitor--MNC output needs work
64      - many attributes need to be added (most are currently blank)
65    o mnc-ify theaim_v23 package as requested by Daniel Enderton
66      - many attributes need to be added (most are currently blank)
67    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
68    o add Sadourny like discretization to the 4th.O vorticity advection scheme
69    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
70      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
71         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
72    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
73     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
74    
75    checkpoint57i_post
76    o Diagnostics package was changed: diagnostic allocation is now deactivated
77      by setting an empty file name in the namelist (used to be by setting 0 frequency)
78    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
79      add 1rst Order upwind vertical Shear.
80    o add a quick fix for A/B checkpointing in OFFLINE mode
81    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
82      end-run around the C/Fortran linking horror in eesup/src/timers.F
83    o added pkg/runclock: allows user to terminate run based on wall clock
84    o added non-hydrostatic scaling parameter: nh_am2
85    o pkg/my82: futile attempt to make results compiler-independent by adding
86      some "_d 0", etc. no effect.
87    o for mnc output, fill the 'T' coordinate var with myTime and create a
88      separate 'iter' variable for iteration count
89    o pkg/diagnostics:
90      add new capability: output of Global/Regional & per-level statistics ;
91      tested against monitor output (including land & thSIce) on various exp.
92    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
93    
94    checkpoint57h_done
95      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
96      data.diagnostics, data.gchem, data.ptracers) is done.
97    
98    o pkg/diagnostics: prepare for Global/Regional statistics.
99      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
100    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
101      and rename it: DIFFERENT_MULTIPLE
102    
103    checkpoint57h_post
104    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
105    o pkg/diagnostics: change output frequency, now in seconds (instead
106      of Nb of iterations). This requires to change data.diagnostics.
107    checkpoint57h_pre
108    
109    o in mnc, let the user create the output dir if both mnc_outdir_date
110      and mnc_outdir_num are false
111    o add fflags() to pkg/diagnostics which allows one to specify, on a
112      per-file basis, the file precision [default behavior is unchanged]
113    o added diagnostics to pkg/kpp, including computation of mixed layer
114      depth based on a temperature/density criterion
115    o updated verification/natl_box to test the new pkg/kpp diagnostics
116    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
117    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
118    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
119      not mnc -- this mistake was found by JMC and is now corrected
120    
121    checkpoint57g_post
122    o add Adams-Bashforth 3rd Order time stepping:
123      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
124      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
125    checkpoint57g_pre
126    
127    o make lambda[Theta,Salt]ClimRelax spatially varying
128      (default remains spatially uniform constant based on tau)
129    o added new control variables
130      * init. uVel, vVel, etanN
131      * lambda[Theta,Salt]ClimRelax
132    o separate masks used for ctrl_pack/unpack 'from write_grid' output
133      (suggested by G. Forget)
134    
135    checkpoint57f_post
136    o add parameter "baseTime" = model base time = time at iteration zero
137      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
138      account for baseTime shift
139    o move Coriolis arrays from PARAMS.h to GRID.h
140    checkpoint57f_pre
141    
142    o mnc-ifying the seaice package
143    o introduced an alternative length scale calculation for use in the limiting
144      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
145    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
146    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
147      as well as grad(vort3).  Made it compatible with both approximate form
148      for the cubed sphere and full form of these gradients.  Added flag
149      useFullLeith to select between approximate and full form.  
150    o add "d0" in getcon.F to reduce differences between compilers/platforms
151      update output.txt of exp. fizhi-gridalt-hs
152    o change port_rand funtion to allow to set the seed.
153    o fix obscure MNC bug involving conversion between reals and integers
154      - it caused no problems with certain (eg. gcc, ifc) compilers but the
155        new version is now more standards-compliant
156    o adjoint-related modifications
157      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
158      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
159      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
160    
161    checkpoint57e_post
162    o Adding eddy stress controls a la Ferreira et al.
163    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
164    
165    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
166      update output.txt of exp. fizhi-gridalt-hs
167    o add more "Z" dimensions and associated coordinate vars to MNC
168    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
169    o parameter calendarDumps: when set, approximate months (30-31 days) and years
170      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
171      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
172      months and years.  Requires pkg/cal.
173    o diagnostics: add pickup functionality
174      - off by default for backwards compatibility
175      - current version only uses MDSIO -- MNC will be added
176    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
177    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
178    
179    checkpoint57d_post
180    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
181    o modify verification/ideal_2D_oce so that it tests the creation of mnc
182      output from the diagnostics package
183    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
184    o make genmake2 more portable by using ".$FS" instead of ".f" for more
185      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
186    o add coordinate variables to the MNC output from the diagnostics package
187    o change MNC-flags default value: true when useMNC=TRUE
188    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
189      the ability (off by default) to read the grid information using MNC
190    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
191    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
192    o do snap-shot diagnostics at the middle of the time-interval (instead of
193      at the end).
194    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
195      new test for AIM with thSIce + slab-ocean
196    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
197    o move state variable diagnostics to the beginning of the time step ;
198      (note: still needs some work specially for snap-shot diagnostics)
199      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
200    
201    checkpoint57c_post
202    o Change testing option (-ieee) to get closer agreement between g77 & ifort
203    o generate new output.txt files on faulks with g77 & the new -ieee option
204    checkpoint57c_pre
205    
206    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
207      update output.txt of exp. global_ocean.90x40x15
208    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
209      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
210    o add saltFlux(+File) forcing capability with periodicExternalForcing
211    o allow to use pkg diagnostics for GM-Redi & ThSIce output
212    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
213    o improvements for the MNC output from DIAGNOSTICS:
214      - correct handling of the unlimitied dimension
215      - all dims now have associated coordinate variables
216      - variables located at U, V, and Corner ("Z") points are now written
217        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
218        *all* data points are output
219    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
220    o added pkg/seaice/seaice_monitor.F
221    o mdsio_readfield.F can now read files visible only to master MPI process.
222    o pkg/seaice: some test code for ice-modified ocean stress
223    o exf_getffields interpolation defaults to bilinear for all scalar forcing
224      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
225      spurious negative numbers for precipitation and humidity.  Will cause
226      some small numerical differences for integrations using pkg/exf/exf_interp.F.
227    o pkg/ctrl/
228      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
229        May be enabled via doPackDiag
230      *  introduce z-scaling of
231         + gradient (doZscalePack) and
232         + control (doZscaleUnpack)
233    o pkg/mdsio/
234      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
235      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
236    
237    checkpoint57b_post
238    o simplify options in diagnostics_fill arguments (remove weird combinations)
239    o fix MNC coordinate variables so that they now contain per-face index
240      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
241      general, EXCH2 grids are only aligned to a "local" coordinate system
242    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
243    o Implement instantaneous output within pkg diagnostics:
244      setting a negative frequency in data.diagnostics produces
245     "snap-shot" output (as opposed to time-average if freq > 0)
246    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
247      NOTE: change ptracer diagnostics name: use 2 characters to work with
248            more than 9 tracers. Add also diagnostics of advect & diffus flux.
249    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
250      becomes the coordinate variable for the 'T' dimension
251    o add CF-style coordinate variables to MNC
252      - just a first cut:  numbers are meaningless on the cubesphere and
253        missing along the T axis but otherwise it works!
254    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
255    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
256    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
257      this is based directly on what the model compute, so that the content of
258      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
259    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
260    o clean up build options files for SunOS, in particular
261      - remove -traditional from xmakedepend
262      - change -xarch=v9 to -xarch=native for f77
263      - restore use of make (not gmake)
264      - add CC=gcc if using g77
265    o changes per discussion of AM, JMC, & EH3 today:
266      - move redundant "grid" variables out of "state" -- in preparation of
267        creating proper CF-style coordinate variables and in recognition
268        that any/all grid variables can be easily copied (eg. w/NCO) from
269        the grid files into any of the other NetCDF files
270      - *always* output grid variables with MDSIO (this will eventually be
271        changed)
272      - output MNC grid file if useMNC is true
273    o every instance of _END_MASTER() has been found and replaced with
274      _END_MASTER( myThid ) in order to satisfy certain picky Sun
275      preprocessors
276    o re-arrange diagnostics pkg initialisation:
277     - allow each package to extend the available diagnostics list
278     - add some checking and fix small problems (multi-threaded, ...)
279     - new S/R diagnostics_fill (replace fill_diagnostics):
280       look through the short list of active diag. (instead of the long list)
281       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
282    
283    checkpoint57a_post
284    o this set of changes restores TAMC compatibility
285      tested for global_ocean.90x40x15 adjoint on trough
286      (what a pain)
287    
288    checkpoint57a_pre
289    o some modifs in tools/build_options for sunos
290    o call ctrl_pack for ctrl at end for optimcycle=0
291    
292    checkpoint57
293    o add horizontal bi-harmonic viscosity for vertical velocity
294      - new parameter viscA4W (defaults to viscA4)
295      - affects only non-hydrostatic code
296      - to be done: no-slip lateral boundary conditions
297    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
298    o implement Implicit Vertical advection for pTracers
299    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
300      (implemented also for implicit vertical diffusion & advection)
301    o OBCS: extend application of tracer open boundary conditions
302      to a strip beyond the boundary of width Olx/Oly
303    o add call monitor to TAF set of required calls (flow directives)
304      and include in natl_box_adjoint
305    o untangle a few ifdefs related to cost, ctrl, autodiff
306      untangel a few ALLOW_ECCO_OPTIMIZATION
307    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
308      (theta2, salt2 in ecco_cost_weights)
309    
310    checkpoint56c_post
311    o OBCS as control variables
312      - update ctrl_ad_diff.list, obcs_ad_diff.list
313      - remove balance of obcs controls from default
314      - fix index bug nobcs in ctrl_init
315      - fix dummy fields filen in ctrl_pack
316      - add dummy weights for obcs
317    o lsopt: comment out fort.94 output
318    o optim:
319      - remove unnecessary header files
320      - adjusted namelists
321      - add xerbla.F to Makefile
322    o exf:
323      - multiple modifications of exf_check_range
324      - unit change in exf_init_runoff from [m/year] to [m/s]
325    o mdsio:
326      - i/o-vector change debugLevel from debLevA to debLevB
327    
328    checkpoint56b_post
329    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
330      is called from DO_THE_MODEL_IO
331      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
332      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
333      - clean up PTRACERS_WRITE_TIMEAVE a little
334    o add another verification experiment that tests both the cfc-pkg and
335      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
336      reactive tendencies treated inline with regular timestepping
337    o testreport previously did a lousy job of comparing small numbers, so
338      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
339      implemented in the little c-progam tmp_cmpnum.c which is embedded in
340      testreport.
341    o ptracers_monitor: bug fix for MPI
342    
343    checkpoint56a_post
344    o GCHEM: finish reorganizating the package
345      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
346        (introduces another 3D-array for each passive tracer, but only if
347        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
348        gchemTendency is not needed because the timestep is done separately)
349      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
350      - GCHEM is now---more or less cleanly---separate from PTRACERS
351      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
352        so clear to me how that should be done in a general way.
353    o CFC: improve formatting of output in CFC_ATMOS
354    o PTRACERS:
355      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
356        that ALL experiments with ptracers enable can be checked. This makes
357        GCHEM_MONITOR obsolete.
358      - include a runtime parameter PTRACERS_monitorFreq that defaults to
359        monitorFreq
360      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
361    o add PTRACERS (PTR0[1-5]) to testreport output
362    o exf_check_range:
363      * default changed to .TRUE.
364      * will check values for niter0 if debLevA, every timestep if debLevB
365      * STOP in exf_check_range if 'out of range'
366      * range chosen generous to allow for potential extema
367      TBD: a version with stricter range
368           permitted range would be runtime parameters
369    o GMredi:
370      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
371      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
372      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
373    o GCHEM:
374      - move call to GCHEM_FORCING_SEP, so that it is now called before
375        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
376      - introduced a useGCHEM runtime flag and applied it everywhere.
377      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
378        this flag is now only visible within GCHEM-pkg routines.
379      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
380        be replaced by a 3D array that is computed before thermodynamics; for
381        this, the tracer ID iTracer had to be included into the parameter list
382        of ptracers_forcing
383      - set up forward_step to call gchem_forcing, that will replace
384        gchem_forcing_int in ptracers_forcing
385      - cleaning up
386    o small cleaning of exch2: remove files that are also in eesupp/src
387    
388    checkpoint56
389    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
390    o mnc: cleanup "full" files--fixes out-of-memory problem
391    o ECCO-GODAE
392      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
393      * fully merged and updated from SIO code
394        windstress sign change affects
395        - exf_inscal_[u/v]stress
396        - sign of xx_tau[u/v] adjustments
397        - signs in cost_scat
398      * ctrl_get_gen: avoid update of tau[u/v] for first few days
399      * natl_box_adjoint updated and compressed
400      * 2-level checkpoint switch added
401        (tested in EXP. 1 of natl_box_adjoint)
402      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
403    o SVD
404      * first complete, non-hacked version for SVD calculations
405      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
406        performed via direct access files admtlm_vector.it????
407        (via ctrl_[un]pack)
408      * optimcycle is used for ARPACK iteration counter
409        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
410      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
411        and add linear transforms where necessary
412      * controls are initial/final SST, SSS (can be extended; need to check
413        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
414    o mdsio: filename info to both stderr, stdout
415    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
416      from sign change
417    
418    checkpoint55j_post
419    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
420      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
421    o add consistent build directories and .cvsignore files to verification
422    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
423    o make all subroutines 30 or less characters in length for certain older
424      compilers to work (a thorough search only turns up two routines in
425      pkg/ptracers)
426    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
427      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
428    
429    checkpoint55i_post
430    o change arrays for total vertical diffusivity (2.D if explicit,
431      3.D if implicit) ; each ptracer uses its own background value.
432    o added mnc/NetCDF output capability to ocn_compon_interf
433      - added bits to verification/cpl_aim+ocn so that it can run on
434        ITRDA and other clusters without the mpirun "-wd" option
435    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
436      configuration
437    o give MNC the ability to create additional files rather than
438      exceeding a specified file size limit "MNC_MAX_FILESIZE"
439      - the default is just less than 2GB which is a practical limit
440        on many systems
441    o Compute the non-local term using either KPP vertical diffusivity (=default)
442       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
443    
444    checkpoint55h_post
445    o add verification test "vermix"
446    o remove all the *_ioinc flags and replace with the single global
447      outputTypesInclusive flag
448    o allow to set a vertical profile of vertical diffusivity for T & S
449    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
450    o useMNC moved from data.mnc to data.pkg
451    
452    checkpoint55g_post
453    o Renaming carbon AD experiments to comply with testreport conventions
454    o Updating adjoint of Held-Suarez hs94.1x64x5
455    o Fixing directives for non-ECCO forward_step, after ECCO directives
456      have been fixed to avoid recomp. of do_oceanic_phys
457      Works well for global_ocean.90x40x15,
458      but recomp. issue remains for carbon
459    o Updating adjoint output for natl_box_adjoint after
460      pkg/ecco has been modified (see taga c55d_post)
461    
462    checkpoint55f_post
463    o rename to timeave_init_fixed
464    
465    checkpoint55e_post
466    o some delicate re-shuffle of store directives to avoid one
467      extra call of do_oceanic_physics
468      affects ecco_the_main_loop.F, do_oceanic_physics.F
469      checkpoint_lev1_directives.h
470    o NB: this may break global_ocean adjoint temporarily,
471      but it is clear how to fix it. Will do later, need this now.
472    
473    checkpoint55d_post
474    o ECCO specific cost function terms (up-to-date with 1x1 runs)
475    o ecco_cost_weights is modified to 1x1 runs
476    o modifs to allow observations to be read in as
477      single file or yearly files
478    o enable to read exf forcing fields as either
479      single file or yearly files (flag useExfYearlyFields)
480    checkpoint55d_pre
481    
482    o switch between 2-level and 3-level checkpointing
483    o add ability of MNC to write local and "partial" (eg. 2D slices where
484      the full 3D field is never actually stored) arrays to NetCDF files
485      with the correct (that is, the complete multi-dimensional) set of
486      array indicies
487      - used in mom_vecinv() to write the diagFreq output
488      - tested (demonstrated) in verification/aim.5l_cs
489    o further mnc-ification
490      - add verification/lab_sea to the list with mnc setups
491      - fix undefined mnc v-names in cd_code
492      - add kpp to mnc output (both snapshot and timeave)
493    o non-hydrostatic code
494      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
495        in calc_gw.F
496      - defaults to viscAh
497      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
498        friction or Leith) in non-hydrostatic mode, as long as there is
499        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
500    o pkg/cost
501      extend simple cost functions to treat time mean quantities
502      (T,U,V) via cost_accumulate_state from cost_tile
503    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
504        be 2 times larger than the minimum size the advection scheme requires.
505        now get a perfect conservation of salt in advect_cs test-exp (updated)
506    o GGL90 (Gaspar's TKE mixed layer)
507      - add horizontal diffusion of TKE, requires exchanges in
508        do_fields_blocking_exchanges, horizontal diffusivity is zero by
509        default. In OPA there is no horizontal diffusion of TKE but the
510        mixing coefficients are computed from a horizontal average of TKE of
511        6 points or so. I think that diffusion has a little more physical
512        justification.
513      - clean up ggl90_calc in the hope of reducing memory usage (this hope
514        was in vain)
515      - mask tke-variable in ggl90_init
516    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
517    o fix biharmonic diffusion on CS-grid.
518    o more obcs stuff
519      - added obcs_external_fields_load as an alternative to the EXF-pkg option
520        for reading boundary values. This routine is called from
521        obcs_prescribe_read
522      - updated obcs_check
523      - changed sponge layer relaxation parameter units for days to seconds
524      - turned off sponge layer by default
525      - changed argument list of OBCS_CALC to myTime+deltaTclock
526      - fixed about 35 bugs in obcs_external_fields_load
527    
528    checkpoint55c_post
529    o obcs stuff
530      - new runtime flags useOBCSprescribe, useOBCSbalance
531      - re-arranged obcs_calc
532      - moved exf_getobcs to obcs_prescibe_read
533        obcs_prescibe_read is called after ORLANSKI stuff
534        and independent of it (executable can contain all).
535      - updated obcs_check
536      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
537        These may be necessary only if tangential velocities are
538        prescribed at OB, not sure, needs testing.
539    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
540      which simplifies the calls and passes the ifc check-bounds test
541    
542    checkpoint55b_post
543    o add a 2D scalar, Z location, exchange_2 routine.
544    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
545      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
546      affects advect_cs results (for the wrong reason): update output.txt
547    o use a more standard discretization for biharmonic viscosity ;
548     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
549      affects results of dome set-up: update output.txt
550    o fix gad_advection.F (CubedSphere part), back to version 1.23
551    o fix bug in mom_vi_del2uv.F (CubedSphere part).
552    
553    checkpoint55a_post
554    o merged code to
555      * prescribe/read time-dependent open boundaries
556        (works in conjunction with exf, cal)
557      * sponge layer code for open boundaries
558      * each boundary N/S/E/W now has its own CPP option
559        (healthy for the adjoint)
560    
561    checkpoint55
562    o up-to-date adjoint of previous breaks
563      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
564      - global_ocean_ebm: adjoint still needs fix (TLM ok)
565      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
566      - carbon: * remove tr1-related adjoint verification
567                * add ptracer as control variable
568    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
569      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
570    
571    checkpoint54f_post
572    o in verification/carbin/ remove experiment related to
573      ALLOW_PASSIVE_TRACER (array tr1 etc)
574      code_ad/ input_ad/ results_ad
575    
576    o add two new packages
577      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
578        + subject to optimization (memory)
579      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
580        + subject to reordering (many GOTOs in the original code)
581        + so far opps is called for every (i,j) point, and then operates in
582          the vertical; one may want to reorder the scheme in order operate in
583          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
584          fields)
585    o overhaul of IO so that we now have flags for MDSIO and/or MNC
586      - all verification tests compile and run with linux_ia32_g77
587      - defaults are compatible with current input files--nothing
588        should change if you were not previously using MNC
589      - MNC output has been added in numerous places (eg. timeave)
590        but there are still a few writes not yet do-able with MNC
591        (this is in progress)
592      - flags now allow for either/or/both use of MDSIO and MNC and
593        documentation will soon follow
594      - numerous small formatting cleanups for ProTeX
595    o add version info (via BUILD_INFO.h) to MNC and stdout
596    
597    checkpoint54e_post
598    o add two new packages
599      - pp81 (Packanowski and Philander, 1981), Richardson number and
600        stratification dependent mixing
601      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
602      - these scheme operate in a similar manner as KPP (without ghat, of
603        course), however there is only one diffusivity that is used for both
604        temperature and salinity (and passive tracers)ç
605    o add offline package
606    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
607      provided by Stephanie Dutkiewicz
608    o genmake2: add ability to search for C compilers and cleanup test output
609      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
610    
611    checkpoint54d_post
612    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
613    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
614      leading to additional shift by 5 days each year of integration
615       (i.e. leading to considerable offset over the years)
616    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
617    o start with no AB and no initial filtering (staggerTimeStep):
618      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
619    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
620      (external loading & cpl import/export stay in forward_step.F)
621    o update coupling interface to work with new staggerTimeStep
622    o change MDSIO ptracers_pickup.
623    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
624    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
625    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
626    
627    checkpoint54c_post
628    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
629      this affects (truncation error) output.txt of test-exp:
630       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
631    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
632    o change Qnet to always be the net heat flux, (+upward).
633      affects (truncation error) output of natl_box exp.: updated
634    o define the max number of passive tracers in PTRACERS_SIZE.h
635    o start to test mnc routinely in exp0
636    o add sea-ice loading (sIceLoad) as a new forcing field.
637    
638    checkpoint54b_post
639    o add testreport "-j JOBS" option for parallel builds (tested and pretty
640       impressive on Altix and Opteron systems)
641    o diagnostics can now write NetCDF files through the mnc package
642    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
643    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
644    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
645      affects (truncation error) output of lab_sea & natl_box exp.: updated
646    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
647    
648    checkpoint54a_post
649    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
650    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
651    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
652    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
653      + internal_wave (shift in writing cg2d_ini_res)
654    checkpoint54a_pre
655    
656    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
657      - modified verification/lab_sea and natl_box_adjoint accordingly
658    
659    checkpoint54
660    checkpoint53g_post
661    o prepare splitting of thermodynamics: store convect.counter in common block
662    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
663      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
664    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
665    o new parameter "nShapS": allow to treat differently S from T (nShapT)
666    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
667    o restore adjointability
668    
669    checkpoint53f_post
670    o modifications that affect AIM experiment results (update output.txt):
671      - no advection of S at top interface Nr (pkg/generic_advdiff)
672      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
673    o AIM pkg:
674      - include stability function into surf.Flux derivative relative to Tsurf
675      - calculate clear-sky radiation & surface temp. change (for diagnostics)
676    
677    checkpoint53e_post
678    o merged cylindrical coord configuration
679    o added rotating_tank experiment
680    checkpoint53e_pre
681    
682    checkpoint53d_post
683    o faulks upgraded: re-generate output.txt that have changed:
684       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
685    o Added Bryan and Lewis, 1979, vertical diffusivity profile
686    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
687    o added Sadourny discretization of Coriolis
688      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
689      - re-enabled use of omega3 (useAbsVorticity)
690    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
691      vector-invariant equations
692      - note: does *NOT* yet use same variable visc. for no-slip BC's.
693    o recoded the lateral boundary conditions for non-hydrostatic w, this time
694      hopefully without new bugs
695      - still to do: biharmonic friction for non-hydrostatic w
696    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
697    o regenerated output for global_ocean_ebm (using -ieee)
698    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
699      of mom_common/
700      - simple re-arrangement of instructions within computing loop
701    checkpoint53d_pre
702    
703    checkpoint53c_post
704    o new version of coupler for AIM+thSIce and Ocean models
705     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
706     - land: change Evaporation of snow
707     - aim with thSIce: fix bug in snow-precip.
708    o changes to calc_gw.F
709     - bug fix for w^2 term near the bottom boundary
710     - (hopefully) improve the lateral slip boundary condtions for use with
711        partial/looped cells
712      - because the bug fix changes two verification experiments anyway (exp5
713        and plume on slope), change the lateral boundary condition from half slip
714        to the value of no_slip_sides
715    o ebm package wasnt quite up to the parallel task. Fixed that.
716    o Adjoint of EBM package + verification
717      * TLM OK
718      * ADM not sufficient accuracy yet (needs further testing)
719    
720    checkpoint53b_post
721    o Commiting new energy balance model to repository
722      * package is pkg/ebm
723      * verif. is verification/global_ocean_ebm
724      * references are in ebm_driver.F
725    C      * X. Wang, P. Stone and J. Marotzke, 1999:
726    C        Global thermohaline circulation. Part I:
727    C        Sensitivity to atmospheric moisture transport.
728    C        J. Climate 12(1), 71-82
729    C      * X. Wang, P. Stone and J. Marotzke, 1999:
730    C        Global thermohaline circulation. Part II:
731    C        Sensitivity with interactive transport.
732    C        J. Climate 12(1), 83-91
733    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
734    C        Destabilization of the thermohaline circulation
735    C        by atmospheric eddy transports.
736    C        J. Climate 7(12), 1870-1882
737    o Will need long integration testing.
738    checkpoint53b_pre
739    
740    o created pkg/mom_common in preparation for variable viscosity code
741    o renamed and split ini_mnc_io
742    o pkg/land: only liquid water can diffuse or run-off
743    o AIM using land: soil wetness availability account for snow
744    o added printMapIncludesZeros to EEPARMS namelist
745    
746    checkpoint53a_post
747    o restore TAMC compatiility for exf_constants.h
748      (no usage of _d in .h)
749    o Additional storing in KPP in an attempt to fix
750      TAMC problem with adjoint of KPP code.
751      (no success...)
752      Identical code works fine with TAF.
753    o Fixed verification/natl_box_adjoint experiments.
754      Initial conditions for Experiments 4 and 5 are now
755      set to "SEAICE_initialHEFF=0", which is more reasonable,
756      and hence gives results closer to that of Experiment 2.
757      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
758    
759    checkpoint53
760    o stable checkpoint with up to date adjoint
761      TLM tests only run for 1st grdchk at the moment. Its unclear if
762      this is a code problem or a problem with resetting code for g_
763      variables that is being autogenerated wrong.
764      Otherwise:
765       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
766       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
767         are both still in chaos following their security messes.
768    
769    checkpoint52n_post
770    o various build (mostly genmake2) changes including:
771      - ability to build/run more easily within Cygwin and MacOS X
772      - more complicated Makefiles with a stronger dependence on Gnu Make
773    o pkg/seaice modifications
774      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
775        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
776        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
777      - changed proxy for geostrophic velocity and updated
778        verification/lab_sea/results/* accordingly
779      - removed ADI dynamic solver from pkg/seaice
780      - replaced all occurrences of 1/CSTICE or 1/CSUICE
781        they caused a segmentation fault under certain circumstances
782      - removed unused field WATR
783    o bug fix in exf-package:
784      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
785         now reflect that.
786    o small fixes in the cal-package:
787      - set reference date to first of January for the 'model'-calendar
788      - failing of cal_CheckDate in cal_FullDate now actually results in a
789        warning
790    o small modifications in exf-package to increase flexibility:
791      - change climtempfreeze from a constant to a runtime parameter that
792        is specified in data.exf_clim (default = -1.9)
793      - introduce runtime parameter windstressmax (default = 2.0) that is
794        specified in data.exf
795    o fix in pkg/thsice:
796      - update Evap (Tsf changes) to be consistent with Latent heat flux
797      - maintain snow precipitation unchanged (even if Tsf >=0).
798     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
799    
800    checkpoint52m_post
801    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
802      this does not change any of the results, because myIter=0 in swfrac always
803      lead to jwtype=2 (the default anyway), but the call makes little sense
804      as a default
805    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
806    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
807      atmospheric model (AIM) to use it ; add a "slab ocean" component.
808    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
809    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
810    o extending useSingleCpuIO option to work with new exch2 I/O format
811      - old-style, missing-tile I/O is still accessible by defining CPP
812        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
813    o monitor package can write to NetCDF files and/or STDOUT
814    o fix re-definition bug in MNC_GRID_INIT_ALL()
815    o doc/api_reference added
816      - a framework for building an API Reference Manual using all
817        the "protex" comments embedded in the code
818      - see pkg/generic_advdiff, pkg/mnc for examples
819    o MNC:
820      - make myThid the last argument for all subroutines
821      - new default for the grid files: NO halos
822      - add useMNC and other run-time flags
823      - separate per-file-group handling of the unlimited dimension
824      - early initialization of MNC w/ flags read at the eeboot stage
825        and lookup tables set in initialize_fixed
826      - write all MNC output to a freshly-created directory
827    o thermodynamics sea-ice (thsice) is now tested with testreport.
828    o test exp. advect_cs: use the standard cs32 grid ; update output.
829    o Added functionality to grdchk:
830      pick global i,j,k position (or nearest wet) where to perform check.
831    
832    checkpoint52l_post
833    o new land formulation:
834      a) use ground enthalpy as prognostic variable to ensure exact
835         energy conservation.
836      b) account for water temperature and for latent heat of freezing
837         in all processes (rain, run-off, ground storage)
838      c) compute surface and ground temperature implicitly.
839    o aim_v23 modification for new land model:
840      a) Treat separately land / ocean / sea-ice surface fluxes
841         to allow implicit computation of land & sea-ice surface temp.
842      b) add snow precipitation.
843    checkpoint52l_pre
844    
845    o fix problem (when 1 tile is empty) in min/max monitor.
846    o fix bug in timeAve (u,vZetatave in common block)
847    o no restoring terms under ice for pkg/seaice
848    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
849    o bug fix for pkg/seaice pickups
850    o change MNC call locations and add coordinate attributes
851    o mask vorticity at the corner ; affects global_ocean.cs output
852    o fix ini_curvilinear_grid ; test CS experiments with mpi
853    o aim.5l_cs: modify sea-ice fraction input file ; update output
854    o exf: Adding simple range check routine for exf fields after read
855    
856    checkpoint52k_post
857    o removed top-level directory "diags"
858      - we migrated these functions to pkg/timeave a long time ago
859    o fixed bug introduced in pkg/monitor
860    o accuracy ctrlprec = 32 insuffient for gradient checks using
861      averaged fields (I/O via cost_averages)
862      -> use ctrl.h in active_file*.F to control I/O precision.
863    o paramter list of CALL ADTHE_MAIN_LOOP
864    o added initial do_the_model_io to ecco
865    o set all ...Freq to zero after cost_final
866      taveFreq, dumpFreq, pChkptFreq
867    o MAIN and ECCO differentiability restored
868    
869    checkpoint52j_post
870    o fix nchklev in tamc.h for global_ocean...
871    o Bringing flow and store directives up-to-date
872    o Really weird thing!
873      call do_the_model_io from the_main_loop with parameters
874      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
875      TAF places a faulty re-call of initialise_varia
876      after cost_final call which should not be there!
877    checkpoint52j_pre
878    
879    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
880      error messages
881    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
882    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
883      debug output
884    o modfied mdsio_writefield.F to handle non-global files under exch2
885    o update AIM Cubed-Sphere exp (aim.5l_cs):
886      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
887    o update AIM Equatorial Channel exp:
888      use standard aim_v23 pkg and change the SST fields to be more realistic.
889    o globalFile now works with exch2
890    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
891      mon_vort3.F to make exch2 friendly with >1 tile per cube face
892    o limit timeave output for hi-res integrations
893    
894    checkpoint52i_post
895    o removed CPP_EEOPTIONS.h from verification/*/code
896    o updated the tiling for global_ocean_pressure
897    checkpoint52i_pre
898    
899    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
900      the old pkg/aim).
901    
902    checkpoint52h_pre
903    o shortened offending lines in exch2_send_rx?.template
904    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
905    o genmake2: add build & execute test for NetCDF code
906    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
907      old grid files, moved CPP_EEMACROS.h to pkg/exch2
908    o added useSingleCPUIO flag to monitor.F and mon_out.F
909    o added temporary hack for sea-ice dynamics on the cube:
910      metric terms are ignored and it is assumed that
911      there is no sea-ice on cube faces 1, 2, 4, and 5.
912    
913    checkpoint52f_post
914    o added exch2 cube routines to pkg/exch2
915    o modified hs94.cs-32x32x5 to use it
916    o added new grid files to hs94.cs-32x32x5
917    checkpoint52f_pre
918    
919    checkpoint52e_post
920    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
921      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
922    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
923      to work with implicit vertical advection and AB ;
924    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
925    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
926     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
927    checkpoint52e_pre
928    
929    o fix bug in impldiff when Nr=1 or Nr=2.
930    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
931    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
932    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
933      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
934    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
935    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
936    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
937    
938    checkpoint52d_post
939    o re-tiled many expts to allow comparison in multi-processor mode
940      - updated output accordingly
941      - changed hs94.128x64x5 to use intial T from file rather than use the
942        random number generator
943    o add infrastructure in model routines for fizhi and gridalt packages
944    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
945    o changes to permit hi-res, cubed-sphere, configuration
946      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
947      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
948      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
949        of surface winds for the cube
950      (A verification experiment, based on global_ocean.cs32x15, but with
951       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
952       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
953       complete with example surface forcing files and matlab scripts to look
954       at the output and compare it with that of global_ocean.cs32x15.)
955    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
956       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
957       to conform to the common rule.
958    o check-in the first version of the coupler + interfaces for multi-components
959       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
960       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
961       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
962       - ocean and atmos. share the same horizontal grid (no interpolation).
963       - exchanges between component and coupler is done in forward_step
964    o new verification experiment, cpl_aim+ocn:
965       coupled ocean - AIM atmosphere on cs32 grid.
966    
967    checkpoint52d_pre
968    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
969    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
970    
971    checkpoint52c_post
972    o Fixing OPTIONS files for use of exf:
973      - ALLOW_ECCO not needed
974      - ECCO_CPPOPTIONS.h should not be included from
975        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
976        as has been the case in the past
977      - All cal/exf related options are currently set in
978        single header file. Should remain so until we
979        agree on a consistent new policy.
980    o Removed all CPP options for cal package.
981      cal has no more CPP options.
982    o modified STOREs in GAD_ADVECTION
983    o corrected key comp. for passkey
984    
985    checkpoint52b_post
986    o new version: "thsice" of thermodynamic sea-ice pkg:
987     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
988     - modify fluxes but do not change theta directly;
989     - light cleaning of bulk_force pkg (still needed with thsice).
990     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
991       + output_thsice.txt to test thsice & bulk_force pkgs.
992    o put back grid & coriolis monitor output.
993    checkpoint52b_pre
994    
995    o call "do_the_model_io" at the beginning (=> dump initial state)
996    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
997    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
998      (need info on NUMBER_OF_PTRACERS)
999    o missing PTRACERS headers in some routines
1000    o default tamc.h in pkg/autodiff supposed to crash
1001      to ensure proper customization
1002    
1003    checkpoint52a_post
1004    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1005      - moved surfaceTendencyTice from pkg/seaice to main code
1006      - subroutine FREEZE_SURFACE now limits only surface temperature
1007        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1008        => new output.txt for global_ocean.cs32x15 & global_with_exf
1009      - keep the old version of FREEZE for backward compatibility;
1010        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1011      - corresponding modifs for TAF directives
1012    o added surface flux output variables to TIMEAVE_STATVARS
1013    o time-averaged output for pkg/ptracers
1014    o fix problem with ECCO-related divided adjoint
1015      snapshot file was missing some ad-variables,
1016      but no warning issued by TAF
1017    
1018    checkpoint52a_pre
1019    o some bug fixes for #undef REAL4_IS_SLOW
1020    
1021    checkpoint52 = ecco_c52_e35
1022    o after testing adjoints of checkpoint51u_post
1023    
1024    checkpoint51u_post
1025    o this is the post-merge tag of the ecco-branch
1026      (needs another clean checkout and re-testing)
1027    o various natl_box_adjoint configs and results
1028      but no input fields
1029    o obcs adjoint not yet merged!
1030    o adding ECCO global 1x1 and 2x2 degree configs
1031    o updated/extended some store directives for seaice
1032    o pkg/ecco now containes ecco-specific part of cost function
1033    o top level routines the_main_loop, forward_step
1034      supersede those in model/src/
1035      previous input data.cost now in data.ecco
1036      (new namelist ecco_cost_nml)
1037    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1038    
1039    checkpoint51t_post
1040    o this is the pre-merge tag of the ecco-branch
1041    
1042    checkpoint51s_post
1043    o cleanup: removed various obsolete #define-s
1044    o pkg/grdchk
1045      - renamed 'ph-grd 3' to 'grad-res'
1046      - merged from ecco-branch
1047        (remaining bug fixes for obcs gradient checks)
1048      - additional high-precision output for testreport
1049        (grep for 'precision_grdchk_result')
1050    
1051    checkpoint51r_post
1052    o cleaned up or removed CPP_OPTIONS.h files
1053    o updated results for some of the tests to reflect the new
1054      optfiles (-ieee: -O0 instead of -O3)
1055    
1056    checkpoint51q_post
1057    o cd_code:
1058      - moved cd_scheme.F -> cd_code_scheme.F
1059      - separate read_checkpoint from cd_code_ini_vars.F
1060      - separated cd_code part from write_checkpoint
1061      - updated AD_SOURCE, generated .flow
1062      - added CD_CODE_VARS.h to the_main_loop
1063      - Moving cd_code specific store dir.s to pkg/cd_code
1064    o ctrl package totally restructured
1065      - pack/unpack now optional and decoupled from
1066        xx_/adxx_ I/O
1067      - ctrl_pack/unpack cleaned
1068        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1069      - confined inclusion of AD_CONFIG.h to where necessary.
1070    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1071    
1072    checkpoint51p_post
1073    o create initial cd_code package
1074      - WARNING: the initialization of fields within packages
1075        is broken because INI_FIELDS (where READ_CHECKPOINT is
1076        called) is called *before* PACKAGES_INIT_VARIABLES.
1077        This seems to be backwards since
1078        1) its important to initially zero the entire field including
1079           the "halo" region
1080        2) zeroing needs to be done *before* reading pickup info
1081           and the pickup call might or might not happen in any
1082           particular run
1083      - this needs an overhaul for R2
1084    o cleanup verification/*/code/GMREDI_OPTIONS.h
1085    o cleanup testreport
1086    
1087    checkpoint51o_post
1088    o bringing AD-related verif's up to date with genmake2

1090      - global_ocean.90x40x15/
1091      - hs.94.1x64x5/
1092      - (front_relax/ )
1093    o (more) consistent directory structure for AD-related verif.'s
1094    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1095    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1096    o bug fix in find_alpha.F for MDJWF:
1097      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1098        change rho -> rho-rhoConst
1099      - replace call find_rho to find_rhonum
1100    o initialisation of rFlx extended to full array (required by TAF)
1101      and shifted to thermodynamics
1102    o removed PTRACERS.h in ptracers routine
1103    o added surfacetendencyPtr to S/R parameter list pracers_forcing
1104    o Correcting initialisations for fVerU, fVerV.

1107    o Replacing delZ by delR in pkg/ctrl/
1108    checkpoint51o_pre
1109    
1110    o undid all of cp51 pending some cleanups and discussion
1111    o added the [#include "AD_CONFIG.h"] statement to all files that need
1112       it for adjoint/tl #defines
1113     o re-worked the build logic in genmake2 to support AD_CONFIG.h
1114     o removed tools/genmake since it no longer works
1115    
1116    checkpoint51n_post
1117    o modifications to make FREEZE flux visible to pkg/kpp
1118      - moved surfaceTendencyTice from pkg/seaice to main code
1119      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1120      - subroutine FREEZE now limits only surface temperature
1121        (this means new output.txt for global_ocean.90x40x15,
1122         global_ocean.cs32x15, and global_with_exf)
1123    o added surface flux output variables to TIMEAVE_STATVARS
1124    
1125    checkpoint51n_pre
1126    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
1127    o added [#include "AD_CONFIG.h"] to all files that use the following
1128      defines:

1131      - ALLOW_ECCO_OPTIMIZATION
1132    
1133    checkpoint51m_post
1134    o incorporating changes to get TAMC/TAF working in genmake2
1135      - added new TAMC/TAF targets to the Makefile
1136      - various cleanups related to package handling
1137      - these changes should have no impact on the forward model
1138    
1139    checkpoint51l_post
1140    o changes to pkg/cal and pkg/exf that allow and speed-up long integrations
1141     - faster algorithm for cal_addtime.F
1142     - higher precision arithmetic, where needed
1143     - pkg/exf *startdate variables changed from calendar date to
1144       model integration time
1145    
1146    checkpoint51l_pre
1147    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
1148    o enable to apply restoring on S & T only in a latitude band.
1149    o update output (external_forcing_surf modif. change truncation errors)
1150       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
1151    
1152    checkpoint51k_post
1153    o change default to: useNHMTerms=.FALSE.
1154     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
1155       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5
1156     - new output.txt for idealized oceanic exp (NHMTerms are now turned off):

1177           - pkg_ad_diff.list
1178           - pkg_ad_check_lev?_dir.h
1179    
1180    checkpoint51i_post
1181    o merge of the branch-genmake2

1212    o Added on-the-fly spatial interpolation capability
1213        "USE_EXF_INTERPOLATION" to pkg/exf.
1214      - This is a temporary Cartesian-grid hack until
1215        the super-duper ESMF coupler becomes available.
1216      - See verification/global_with_exf/README for usage example.
1217      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
1218        flags and modified pkg/seaice accordingly.
1219    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
1220        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
1221        non-local transport term.
1222    
1223    checkpoint51e_post
1224    o pkg/mom_vecinv:
1225      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)

1237    o modif's to restore TAMC compatibility
1238      - avoid "_d" constructs in PARAMETER declarations
1239      - avoid interrupting lines by comment lines
1240    o Use cluster local disks for purely local I/O

1242      (merged from ecco-branch)
1243      - new active_file_loc... and mdsio_..._loc routines
1244      - affected packages: autodiff, ctrl, grdchk, mdsio
1245    
1246    checkpoint51c_post
1247    o introducing integer flag debugLevel
1248      - debLevZero: suppress all output
1249      - debLevA: standard
1250      - debLevB: equivalent to current debugMode=.TRUE.
1251    o introducing pathname variable mdsioLocalDir for mdsio
1252      that can be specified at runtime
1253      (relevant for cluster I/O to local disk)
1254    `
1255    >>>checkpoint51b_post
1256    adjoint of ptracers
1257    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1258    o extended state in checkpoint_lev?, etc.
1259    o alternative ctrl/cost with tr1 or ptracer
1260    o new comlev1_bibj_ptracers
1261    o new ptracers.flow
1262    o made ptracers_forcing same as external_forcing_s
1263    o added verification for adjoint with ptracers
1264      - adm. grdchk fail so far
1265      - tlm. grdchk OK
1266      - checked tapelev/comlev recomputations: OK
1267    <<<checkpoint51b_pre
1268    
1269    checkpoint51a_post
1270    o added code for biogeochemistry package

1272      - new subroutine in ptracers
1273    o modify code for biogeo packages
1274      - in model/src and pkg/ptracers
1275    
1276    checkpoint51
1277    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1278      - autodiff, ctrl, exf, grdchk, seaice
1279      kept separate packages
1280      - cost, ecco, obcs
1281    o updating verification/internal_wave, verification/lab_sea
1282      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1283    
1284    checkpoint50i_post
1285    o Preparing next differentiable checkpoint and sync
1286      of MAIN vs. ecco-branch
1287      - 1st step: this one is differentiable
1288      - 2nd step: next(! not this) checkpoint will have updated packages
1289                  from ecco-branch)
1290    
1291    checkpoint50h_post
1292    o new package "land": provide surface BC for AIM.
1293    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1294    o AIM: use true log-P extrapolation for near surface temp (= as in
1295        F.Molteni paper) ; update aim.5l_cs output.
1296    o New variable in PARM03 for more flexible pickups
1297    o somewhat cleaned package initialisation sequence for
1298      ctrl/ cost/ ecco/ in packages_... routines
1299    
1300    checkpoint50g_post
1301    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1302      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1303      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1304        made the default because of faster convergence than ADI
1305    
1306    checkpoint50f_post
1307    o exf totally restructured
1308      - replaced all exf_set_ routines by one generic exf_set_gen.F
1309        and made sure it's still differentiable
1310      - split exf_getffields.F into new exf_bulkformulae.F
1311      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1312      - updated adjoint/makefile and relevant verif. accordingly
1313    
1314    checkpoint50f_pre

1322     o removed lots of single quotes from comments
1323    
1324    checkpoint50e_post
1325    o make KPP work with PTRACERS
1326     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1327       nearly a copy of kpp_transport_s
1328     - there is no analogue to SurfaceTendencyS, so I have to use
1329       gPtr(of the surface layer) instead
1330    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1331    checkpoint50e_pre
1332    
1333    checkpoint50d_post
1334    o change kpp output from multiple-record state files to single-record state
1335      files analogous to write_state.F
1336    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1337      analogous to the cg2d-related output.
1338    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1339      so that writing to internal file fn (with length 512) fails.
1340    checkpoint50d_pre
1341    
1342    checkpoint50c_post
1343    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1344    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1345    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1346    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1347    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1348    
1349    checkpoint50c_pre
1350    Merging from release1_p13:
1351    o bug fix for pkg/seaice dynamic solver
1352    o Added SEAICE_initialHEFF to pkg/seaice
1353    
1354    checkpoint50b_post
1355    o store u*,v* in gU,V instead of in guNm1,gvNm1
1356    o in order to put the momForcing out of the Adams-Bashforth:
1357      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1358      to timestep.F
1359    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1360    o re-generate output for highly sensitive test-exp:
1361       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1362    
1363    checkpoint50b_pre
1364    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1365    o corrected CPP option mismatch in exf_Bulk... functions for case
1366      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1367    
1368    checkpoint50a_post
1369    o Bug fix for merging between c50 and KPP.
1370      ikey was passed from thermodynamics to kpp_calc via
1371      common block rather than being recomputed in kpp_calc,
1372      in contradiction with new key itdkey.
1373      New key ikppkey created, and tamc.h headers updated.
1374    
1375    checkpoint50
1376    - 2nd step of merge with ecco-branch:
1377      merge changes in ecco-branch back into main trunk
1378    - bug fix in find_alpha
1379    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1380    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1381    - merged some sliced AD support routines
1382    
1383    checkpoint49
1384    merged from ecco-branch:
1385    o exf:
1386      - Enable initialisation of forcing fields to constant
1387        (runtime) values.
1388      - in exf_getffields.F
1389        Reduce i-/j-loop to interior domain, discarding overlaps.
1390        That also fixes wrong TAF-key computations for key_1, key_2
1391        with bulf formulae.
1392      - exf_init.F modify #ifdef for exf_init_evap
1393      - exf_getffieldrec.F, ctrl_getrec.F
1394        The following INT-usages are not safe:
1395          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1396          fldcount = int(fldsecs/fldperiod) + 1
1397        and were modified.
1398    o autodiff: checkpoint_lev...
1399      - updated storing for bulk formulae (some arrays were missing)
1400      - added state for seaice package
1401      - synchronized with main branch
1402    o DIVA:
1403      Modif.s in
1404      - the_main_loop.F
1405      - the_model_main.F
1406      and added cost_final_restore.F cost_final_store.F
1407      o With these changes, it is possible to fully separate
1408        the first forward run to compute the cost function (mdthe_main_loop)
1409        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1410        into separate model executions.
1411        This enables better tuning of DIVA to given queue sizes.
1412      o Loss of cost function value in consecutive DIVA runs is
1413        fixed by storing to 'costfinal' file.
1414      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1415        beginning/end of adjoint integration is accounted for.
1416      The current changes apply to TAF-1.4.26.
1417      TAF has one remaining bug, requiring one manual change
1418      (see MITgcm manual).
1419    o cal: synchronized between MAIN and ecco-branch
1420    
1421    checkpoint48i_post
1422    o Changes to restore differentiability of code w.r.t. previous tag
1423      (mostly adding new routines to make list and replacing
1424      pressure by totPhiHyd).
1425    o Updated and merged grdchk package
1426      - has both ADM and TLM checks
1427      - works for single- and multi-proc.
1428      - output cleaned
1429      - worked successfully for parallel DIVA
1430    o genmake:
1431      - Adding -platform=SP4
1432      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1433    o Modif. for DIVA:
1434      ctrl_unpack should not be called in intermediate DIVA interval.
1435      (similar thing would apply for active files such as
1436      tbar, sbar, psbar, which should not be reinitialised;
1437      only relevant for ecco-branch)
1438    
1439    checkpoint48h_post
1440    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1441    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1442    o Added SEAICE_initialHEFF to pkg/seaice
1443    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1444    
1445    checkpoint48g_post
1446    --- EOS:
1447    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1448      store total Potential in totPhyHyd for diagnostics & EOS.
1449    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1450    --- Pressure/geopotential gradient:
1451    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1452    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1453      ( changes results of global_ocean_pressure )
1454    o NLFS + z-coord.: add eta*Rho' contribution.
1455    o accurate phiHyd when using interface-W at the middle between 2 centers
1456     ( changes results of ideal_2D_oce )
1457    o includes r* 2nd term in potential gradient.
1458    
1459    checkpoint48f_post
1460    Merging from release1_p12:
1461    o Modifications for using pkg/exf with pkg/seaice
1462      - improved description of the various forcing configurations

1466    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1467      (SBO) core products, including oceanic mass, center-of-mass,
1468      angular, and bottom pressure (see pkg/sbo/README.sbo).
1469    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1470      to avoid negative values in shallow regions.
1471      - updated verification/natl_box/results/output.txt
1472      - updated verification/lab_sea/results/output.txt
1473    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1474    o Added useSingleCpuIO option (see PARAMS.h).
1475    o Updated useSingleCpuIO option in mdsio_writefield.F to
1476      work with multi-field files, e.g., for single-file pickup.
1477    o pkg/seaice:
1478      - bug fix in growth.F: QNET for no shortwave case
1479      - added HeffFile for specifying initial sea-ice thickness
1480      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation

1482      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1483    o pkg/seaice:
1484      - adjoint-friendly modifications
1485      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1486    
1487    checkpoint48e_post
1488    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1489    o dynamics: change definition of computational domain & adapt mom_fluxform
1490      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1491    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1492        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1493        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1494        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1495        inverted_barometer solid-body.cs-32x32x1
1496      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1497    
1498    checkpoint48d_post
1499    o in preparation for r*:
1500     a) use pre-computed gradient of hydrostatic potential:
1501        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1502     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1503        => affects results of glob_oce_pressure (different truncation error)  
1504      update output.txt of ideal_2D_oce & global_ocean_pressure
1505    
1506    checkpoint48d_pre
1507    o in preparation for r*:
1508      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1509      pass the 2 comp. of the grad. as arguments to momentum S/R.
1510      but for the moment, only used if it does not change the results.
1511    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1512    
1513    checkpoint48c_post
1514    Modifications in treatment of initial flux forcing controls
1515    to avoid extra storing of flux fields.
1516    
1517    checkpoint48c_pre
1518    o Added tidal_basin_2d experiment (currently 1D!)
1519    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1520    
1521    checkpoint48b_post
1522    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1523     (modification to pressure gradient not yet implemented)
1524    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1525      (for U & V) that are used for vertical advection of momentum.
1526    
1527    checkpoint48a_post
1528    o In preparation for r*, use temp. array to compute vertical transport
1529       in flux-form momentum pkg. => change results of few test-exp.
1530      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1531                        lab_sea, natl_box & plume_on_slope
1532    
1533    checkpoint48
1534    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1535    
1536    checkpoint47j_post
1537    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1538    o moved adexch from forward_step to addummy_in_stepping
1539    o added exch in ctrl_map_...
1540    o aveFreq.=0. at end of cost_final to avoid overwrite in
1541      reverse checkpointing loop
1542    o Yet more changes in gmredi:
1543      * adgmredi_calc_tensor
1544        avoiding all recomputation of gmredi_slope_limit
1545      * adgmredi_x/y/rtransport
1546        added flag for excessive storing to avoid recomp. of
1547        u/v/rtans, dTdx/y/z
1548        -> this is not really necessary and very memory-consuming
1549      * adgmredi_slope_psi:
1550        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1551      * gmredi_slope_limit
1552        re-activated full calculation of taperfct for case 'ac02'
1553    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1554    
1555    checkpoint47i_post
1556    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1557    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1558      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1559    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1560    o gmredi: fix few bugs.
1561    
1562    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1563    This will be a good checkpoint to plug into the ecco-branch.
1564    o few modif.'s to get latest version adjointed
1565      (mainly kick out code in ini_linear_phisurf)
1566    o modif's to run adjoint with exactConserv
1567    o case GM_BOLUS_ADVEC should be cleaned
1568      S/R gmredi_slope_psi should be cleaned
1569    o verification/carbon now has exactConserv=.TRUE.
1570    
1571    checkpoint47g_post
1572    o time-average AIM output: becomes independent from statvars time-average
1573      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1574    o After TAF bug fix:
1575      Tested adjoint of gmredi package.
1576      Tests were done with checkpoint47 rather than with latest
1577      checkpoint47f_post since the latter is broken for the adjoint
1578      verification/carbon/ contains both ADM and TLM gradient checks.
1579    Here they are, before they get changed/lost/stolen.
1580    Mostly modif.'s to fix numerical sensitivities.
1581    Gradient checks OK for
1582    - GM_taper_scheme:
1583      * clipping
1584      * ac02
1585      * linear
1586      * glw91
1587      * dm95
1588      * ldd97
1589    - GMREDI_OPTIONS:
1590      * GM_VISBECK_VARIABLE_K
1591      * GM_NON_UNITY_DIAGONAL
1592      * GM_EXTRA_DIAGONAL
1593      * GM_BOLUS_ADVEC
1594    in conjunction with data.gmredi parameters to be checked in
1595    in a few minutes under verification/carbon/code/
1596    
1597    checkpoint47f_post
1598    Merging from release1_p10:
1599    o modifications for using pkg/exf with pkg/seaice
1600      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1601        and SEAICE_EXTERNAL_FLUXES
1602      - pkg/exf CPP options EXF_READ_EVAP and
1603        EXF_NO_BULK_COMPUTATIONS
1604      - usage examples are Experiments 8 and 9 in
1605        verification/lab_sea/README
1606      - verification/lab_sea default experiment now uses
1607        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1608    
1609    checkpoint47e_post
1610    o created a tag prior to creating a branch
1611    
1612    checkpoint47d_post
1613    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1614      at the bottom boundary had an erroneous half slip boundary condition
1615    o added bottom drag and no slip boundary condition capabilities to
1616      oceanic pressure coordinates code
1617    o added new verification experiment global_ocean_pressure, this experiment is
1618      also described in the tutorial section of the manual
1619    checkpoint47d_pre
1620    
1621    checkpoint47c_post
1622    o Added a verification experiment for a global cubed-sphere ocean run
1623      -  verification/global_ocean.cubed32x32x30
1624      -  uses pkg/therm_seaice and pkg/bulk_forcing
1625    
1626    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1627    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1628      when using P-coordinate; only implemented for atmospheric config.
1629    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1630      NOTES: requires option NONLIN_FRSURF to be "#define".
1631    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1632    
1633    checkpoint47b_post
1634    Merging from release1_p9:
1635    o pkg/seaice
1636      - removed GOTO's and added taf directives
1637      - double precision constants to reduce the g77 (Linux)
1638        to F77 (SGI) differences reported in release1_p8
1639    o tools/genmake
1640      - added SGI options
1641    o verification/testscript
1642      - updated to that of checkpoint47a_post
1643    o verification/global_ocean.90x40x15/input/eedata
1644      - modified for SGI f77 compatibility
1645    o verification/lab_sea
1646      - added description of sea-ice model
1647      - added missing matlab routines
1648      - added test of thermodynamics parallelization
1649    
1650    checkpoint47a_post
1651    o new pkg: aim_v23
1652     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1653       for now, keep the same surface forcing as before.
1654     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1655     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1656     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1657    o add diagnostic of surface correction term in monitor output
1658    
1659    o bulk_force and therm_seaice
1660    - Two packages:  bulk_force (Bulk forcing)
1661      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1662    - Earlier integration from Stephaine Dutkiewicz
1663      and Patrick Heimbach.
1664    - Two ifdef statements for compile time,
1665       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1666    
1667    checkpoint47
1668    differentiable version of checkpoint46n_post
1669    o bug fix in quasihydrostaticterms
1670    o * "clean" adjoint code (in terms of extensive recomputations)
1671        can now be obtained for all GMREDI options (i.e. for
1672        - GM_VISBECK_VARIABLE_K
1673        - GM_NON_UNITY_DIAGONAL
1674        - GM_EXTRA_DIAGONAL
1675        - GM_BOLUS_ADVEC )
1676      * However, wrong gradient check problem remains unsolved.
1677      * New CPP options have been introduced for different
1678        tapering schemes
1679    o external_fields_load now part of differentiation list
1680    o pressure needs multiple storing;
1681      would be nice to have store_pressure at beginning or
1682      end of forward_step, e.g. by having phiHyd global (5-dim.)
1683      (NB: pressure is needed for certain cases in find_rho,
1684      which is also invoked through convective_adjustment).
1685    o recomputations in find_rho for cases
1686     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1687    o #define ATMOSPHERIC_LOADING should be differentiable
1688    o ini_forcing shifted to begining of initialise_varia
1689    o Incorporating QNVS line search routines into MITgcm
1690      (this is separate code, and therefore not under pkg)
1691      lsopt/, optim/
1692    o Updated verification/carbon/
1693      - #define GM_VISBECK_VARIABLE_K
1694      - GM_taper_scheme    = 'ldd97'    
1695    
1696    checkpoint46n_post
1697    Merging from release1_p8:
1698    o verification/natl_box:
1699      updating new external_fields_load routine
1700    o New package: pkg/seaice
1701      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1702      The sea-ice code is based on Hibler (1979-1980).
1703      Two sea-ice dynamic solvers, ADI and LSR, are included.
1704      In addition to computing prognostic sea-ice variables and diagnosing
1705      the forcing/external data fields that drive the ocean model,
1706      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1707      The implied surface heat flux is then stored in variable
1708      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1709      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1710      non-local transport term.  Because this call precedes model
1711      thermodynamics, temperature under sea-ice may not be "exactly" at
1712      the freezing point by the time theta is dumped or time-averaged.
1713      N.B.: fairly large differences in accuracy occur across
1714            different platforms/compilers; comparison between
1715            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1716            generated output gives:
1717       T           S           U           V
1718      C D M    c        m  s        m  s        m  s        m  s
1719      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
1720      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
1721      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
1722    
1723      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1724    o GAD:
1725      - generated new common blocks to account for call of
1726        same gad routines with differing traceridentities
1727        (needed to modify tracerIdentity indices in GAD.h)
1728      - generated separate common blocks for case useCubedSphereExchange
1729        (Department of Futurology)
1730      - parameter lists to gmredi_?transport: added tracerIdentity
1731      - added new key indices to tamc.h
1732    o external_fields_load:
1733      - added this routine to TAF list
1734      - needed to make some common blocks global and additional storing
1735        along the same lines as exf package (checkpoint_lev?_directives.h)
1736    o exf:
1737      updated external forcing package
1738      - bug fixes carried over from ecco-branch
1739        (missing OBCS_OPTIONS.h in two routines)
1740      - enable easy to use "no forcing".
1741      - added exf I/O for atmospheric loading
1742      - added exf I/O for runoff data
1743      - transfered scaling between exf <-> MITgcm to exf namelist
1744    o Adding new verification experiment global_with_exf.
1745      This verification experiment is almost identical to the
1746      global_ocean.90x40x15 experiment, except that it uses
1747      the exf (and cal) package instead of the
1748      external_fields_load routine (cf README file).
1749    
1750    checkpoint46m_post
1751    o modified testscript to return -- when there are no lines of "%MON" output
1752    o added new flag "quasiHydrostatic" for QH mode
1753      and new routine quasihydrostaticterms()
1754    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1755      New routine: mom_u_coriolis_nh()
1756    o fixed sign of non-hydrostatic metric terms in u and v equations.
1757      Depend on correct sign of gravitySign.
1758    o added work.pc* to .cvsignore in aim directories using ifc
1759    o introduced flag for controllin non-hydrostatic metric terms
1760    o removed gravitySign from PARM04
1761    o switched to g77/ifc from pgf77 in aim experiments
1762    
1763    checkpoint46l_post
1764    o made convective adjustment work with pressure coordinates:
1765     - changed the direction of k-loop in convective_adjustment.F for the
1766       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1767     - adjusted the reference pressure k-index in convective_adjustment.F
1768     - adjusted the convection condition in convect.F (in analogy to
1769       calc_ivdc.F)
1770     - convective_adjustment no longer computes anything on the halos
1771     - removed the warnings about negative salinity from find_rho.F and
1772       find_alpha.F; instead the new routine look_for_neg_salinity, called
1773       at the beginning of find_rho, find_alpha, and find_beta, does a
1774       check of the entire slice, if CPP-option
1775       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1776    checkpoint46l_pre
1777    
1778    checkpoint46k_post
1779    o fixed the verification/global_ocean.90x40x15 experiment:
1780     - new bathymetry (the world according to A., JMC, and M.)
1781     - new initial fields and forcing fields (*.bin files)
1782     - new POLY3.COEFFS (for the next release one should switch to a full
1783       equation of state: JMD95P or MDJWF)
1784     - fixed several errors and redundancies in the data file
1785     - experiment uses looped cells
1786     - added matlab directory with diagnostic scripts for plotting of output
1787    
1788    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1789     - read AIM physics parameters from a file (data.aimphys)
1790     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1791    
1792    checkpoint46j_post
1793    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1794    o move wVel computation at the end of the time step, in S/R integr_continuity
1795    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1796    o update timeave pkg for wVel diagnostic.
1797    checkpoint46j_pre
1798    
1799    checkpoint46i_post
1800    o Clean up AIM package (and keep the results unchanged):
1801      include CPP_OPTION and use IMPLICT NONE in all routines ;
1802      declare all the variables _RL ; use _d 0 for all numerical constants.
1803      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1804    
1805    checkpoint46h_post
1806    o cleaned up the use of rhoNil and rhoConst.
1807      - rhoNil should only appear in the LINEAR equation of state, everywhere
1808        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1809        and the dynamical equations are all divided by rhoConst
1810    o introduced new parameter rhoConstFresh, a reference density of fresh
1811      water, to remove the fresh water flux's dependence on rhoNil. The default
1812      value is 999.8 kg/m^3
1813    o cleanup up external_forcing.F and external_forcing_surf.F
1814      - can now be used by both OCEANIC and OCEANICP
1815    checkpoint46h_pre
1816    
1817     Added code to convert surface volume flux (fresh water) into
1818     a mass flux when using P coordinates in the ocean (OCEANICP).
1819     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1820    
1821    checkpoint46g_post
1822    o Include a new diagnostic variable phiHydLow for the ocean model
1823      - in z-coordinates, it is the bottom pressure anomaly
1824      - in p-coordinates, it is the sea surface elevation
1825      - in both cases, these variable have global drift, reflecting the mass
1826        drift in z-coordinates and the volume drift in p-coordinates
1827      - included time averaging for phiHydLow, be aware of the drift!
1828    o depth-dependent computation of Bo_surf for pressure coordinates
1829      in the ocean (buoyancyRelation='OCEANICP')
1830      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1831        Theta, Salinity, and Pressure in the parameter list. This routine is
1832        presently contained in find_rho.F. This routine does not give the
1833        correct density for 'POLY3', which would be a z-dependent reference
1834        density.
1835    o cleaned up find_rho
1836      - removed obsolete 'eqn' from the parameter list.
1837    o added two new verification experiments: gop and goz
1838      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1839    checkpoint46g_pre
1840    
1841    checkpoint46f_post
1842    o Enable tangent linear (forward mode) gradient checks:
1843      - extended active file handling to g_... files
1844      - added TANGENT_SIMULATION to theSimulationMode
1845      - extended grdchk package accordingly
1846    o added tangent linear setup in verification/carbon/code_ftl
1847    o added adjoint setup in verification/front_relax/code_ad
1848    
1849    checkpoint46e_post
1850    o Added new equation of state -> MDJWF
1851      - EOS of McDougall et al., 2002, JAOT, submitted
1852      - caveat: the equation of state is only valid for a smaller (more
1853        realistic?) range of values than JMD95P/Z and UNESCO
1854      - added masks to the calculation of pressure in store_pressure
1855      - added more check values for density in check_eos (ini_eos.F), some of
1856        the old check values are out of the range of the MDJWF-eos, so don't
1857        expect perfect matches for those
1858    checkpoint46e_pre
1859    
1860    checkpoint46d_post
1861    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1862      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1863      case of pressure coordinates. eosType='JMD95Z' in
1864      combination with buoyancyRelation='OCEANICP' now causes an error.
1865    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1866      in find_alpha/beta.
1867    checkpoint46d_pre
1868    
1869    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1870      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1871    
1872    checkpoint46c_post
1873    o Changes necessary for ocean in p-coordinates
1874     -  Added new buoyancy relation = 'OCEANICP'
1875     -  Added new parameters = gravitySign (this used to be contained inside
1876        the factor dRdZ which I added when we first switched to R coordinates).
1877     X GM/Redi is not compatible (yet)
1878     X bottom drag and no-slip need to be debugged.
1879    checkpoint46c_pre
1880    
1881    checkpoint46b_post
1882    o Added new equation of state -> JMD95Z and JMD95P
1883      - EOS of Jackett and McDougall, 1995, JAOT
1884      - moved all EOS parameters into EOS.h
1885      - new routines ini_eos.F, store_pressure.F
1886    o Added UNESCO EOS, but not recommended because it requires
1887      in-situ temperature (see JMD95)
1888    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1889      unesco.f to be used with POLY3
1890    checkpoint46b_pre
1891    
1892    checkpoint46a_post
1893    o Added (atmospheric) pressure loading
1894      - new field in FFIELDS.h, etc...
1895      - new cpp flag ATMOSPHERIC_LOADING
1896    o Changed hFacC to _hFacC in calc_phi_hyd.F
1897    o Added SHORTWAVE_HEATING to some files for consistency
1898    checkpoint46a_pre
1899    
1900    checkpoint46
1901    further merges from release1_p5
1902    o new ctrl package
1903      - adopted from ECCO environment to enable optimization
1904      - added Eliassen Palm fluxes to controls
1905    o added Eliassen Palm flux controls to gradient check package
1906    o cost package
1907      - Compatible with new ctrl package
1908      - added Eliassen Palm cost hooks
1909      - modif's of existing cost functions
1910    o Adjoint-related bug fixes in kpp:
1911      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1912      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1913    o autodiff package
1914      - flow directives:
1915        + new for S/R do_the_model_io
1916        + enhanced for S/R checkpoint
1917        + new gmredi.flow
1918      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1919        disable adcommon.h/g_common.h by default.
1920      - fixed problem for adjoint of global_max
1921    o modified verification/carbon/
1922    o New setup for adjoint of global_ocean
1923    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1924    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1925    o incorporated hooks for sponge layer code (external_forcing.F)
1926    
1927    checkpoint45d_post
1928    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1929    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1930      (affects plume_on_slope "cg2d" output)
1931    o add new parameter deltaTfreesurf for free-surface time stepping
1932    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1933    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1934    o change phiMin in exp1 (to agree with documentation)
1935    o add new flags:
1936     - T,S forcing inside/outside Adams-Bashforth
1937     - turn off temp,salt advection and/or forcing
1938     - for each tracer, define internal flag for multiDimAdvection & A-B
1939    o monitor: change definition of KE to check conservation of Energy
1940    
1941    checkpoint45c_post
1942    o Removed f90 comments ("!")
1943    o Modified initialisations to enable exf package for MITgcm
1944      (without invoking ECCO_PACKAGE).

1955      (TAF flow dependency)
1956    o in initialise_varia, moved call packages_init_variables
1957      before convective_adjustment_init
1958      (corresponding adjustment of TAF tape initialisation).

1966    
1967    checkpoint44h_post = checkpoint45
1968    o Fix to restore differentiability:
1969      place at which packages_init_variables is called in
1970      initialise_varia is crucial for reverse control flow.
1971    o modifications in GMRedi to enable stable adjoint
1972      (corresponding modif's in thermodynamics, dynamics)
1973    o added missing hook for sponge layer code in external_forcing
1974    o modified test cost functions
1975    o storing in gad_advection (plus removal of write(0,*)!

1979    o modified carbon verif.
1980    
1981    checkpoint44h_pre
1982    o vertical grid option: allow to put the Interface at the middle between
1983      2 cell-centers ; replace delZ in pkg/kpp by drF.
1984    o GM Advective form: Tracers are advected using the residual transport (=
1985      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1986    
1987    checkpoint44g_post
1988    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1989      results) ; ifdef missing in thermodynamics.F
1990    
1991    checkpoint44f_pre,checkpoint44f_post
1992    o added PTRACERS package
1993      This allows an arbitrary number of passive tracers to be integrated
1994      forward simultaneously with the dynamicaly model.
1995      + Implemented so far:
1996        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1997        - I/O and checkpointing
1998        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1999      + Not implemented so far:
2000        - KPP
2001        - OBCS
2002      + No specific example supplied (yet) but global_ocean.90x40x15 has the
2003        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
2004        line in data.pkg.
2005      + This package is disabled by default since it increases storage.
2006    
2007    
2008    o testscript: added -cleanup option
2009    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
2010                 b) enable to filter 2D fields.
2011    
2012    checkpoint44e_pre,post
2013    o re-wrote convective adjustment to use pre-calculated weights
2014      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
2015      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
2016      Original calls to convect() still in place.
2017    
2018    chkpt44d_pre,post
2019    o added missing EXCLUDE_MONITOR flags
2020    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
2021      (incompatible typ in MIN/MAX expressions caused problems
2022      on IBM SP3)
2023    o in genmake added variable MAKEDEPEND
2024      plus resetting for case SunOS
2025    o added timer_stats.c routine for IBM SP3
2026    o removed variables in dynamics
2027    !!! I forgot to create tag chkpt44d_pre !!!
2028    !!! But chkpt44d_pre = chkpt44c_post    !!!
2029    
2030    o real fresh water flux implemented with non-linear free-surface.
2031    
2032    chkpt44c_pre,post
2033    o few fix (mask in shap_s2, EmPmR in external_field_load,
2034      USE_NATURAL_BCS in solve_for_P);
2035    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
2036    
2037    checkpoint44b_pre/_post
2038    o merge of relevant stuff from the ecco-branch:
2039      - genmake: removed $S64 overwrite for case SunOS
2040      - pkg/exf: update and corrections for field swapping and obcs
2041      - pkg/ecco: parameter lists for the_model_main, the_main_loop
2042                  harmonized between ECCO and MITgcm
2043      - pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
2044                      updated checkpointing_lev... lists for obcs
2045      - model/src: minor changes in forward_step, plot_field
2046                   added directive for divided adjoint in the_main_loop
2047      - pkg/mdsio: added mdsio_gl_slice
2048    
2049    o check parameters & config (chkpt44a_pre,post)
