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

819    o aim.5l_cs: modify sea-ice fraction input file ; update output
820    o exf: Adding simple range check routine for exf fields after read
821    
822    checkpoint52k_post
823    o removed top-level directory "diags"
824      - we migrated these functions to pkg/timeave a long time ago
825    o fixed bug introduced in pkg/monitor
826    o accuracy ctrlprec = 32 insuffient for gradient checks using
827      averaged fields (I/O via cost_averages)
828      -> use ctrl.h in active_file*.F to control I/O precision.
829    o paramter list of CALL ADTHE_MAIN_LOOP
830    o added initial do_the_model_io to ecco
831    o set all ...Freq to zero after cost_final
832      taveFreq, dumpFreq, pChkptFreq
833    o MAIN and ECCO differentiability restored
834    
835    checkpoint52j_post
836    o fix nchklev in tamc.h for global_ocean...
837    o Bringing flow and store directives up-to-date
838    o Really weird thing!
839      call do_the_model_io from the_main_loop with parameters
840      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
841      TAF places a faulty re-call of initialise_varia
842      after cost_final call which should not be there!
843    checkpoint52j_pre
844    
845    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
846      error messages
847    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
848    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
849      debug output
850    o modfied mdsio_writefield.F to handle non-global files under exch2
851    o update AIM Cubed-Sphere exp (aim.5l_cs):
852      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
853    o update AIM Equatorial Channel exp:
854      use standard aim_v23 pkg and change the SST fields to be more realistic.
855    o globalFile now works with exch2
856    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
857      mon_vort3.F to make exch2 friendly with >1 tile per cube face
858    o limit timeave output for hi-res integrations
859    
860    checkpoint52i_post
861    o removed CPP_EEOPTIONS.h from verification/*/code
862    o updated the tiling for global_ocean_pressure
863    checkpoint52i_pre
864    
865    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
866      the old pkg/aim).
867    
868    checkpoint52h_pre
869    o shortened offending lines in exch2_send_rx?.template
870    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
871    o genmake2: add build & execute test for NetCDF code
872    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
873      old grid files, moved CPP_EEMACROS.h to pkg/exch2
874    o added useSingleCPUIO flag to monitor.F and mon_out.F
875    o added temporary hack for sea-ice dynamics on the cube:
876      metric terms are ignored and it is assumed that
877      there is no sea-ice on cube faces 1, 2, 4, and 5.
878    
879    checkpoint52f_post
880    o added exch2 cube routines to pkg/exch2
881    o modified hs94.cs-32x32x5 to use it
882    o added new grid files to hs94.cs-32x32x5
883    checkpoint52f_pre
884    
885    checkpoint52e_post
886    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
887      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
888    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
889      to work with implicit vertical advection and AB ;
890    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
891    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
892     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
893    checkpoint52e_pre
894    
895    o fix bug in impldiff when Nr=1 or Nr=2.
896    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
897    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
898    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
899      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
900    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
901    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
902    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
903    
904    checkpoint52d_post
905    o re-tiled many expts to allow comparison in multi-processor mode
906      - updated output accordingly
907      - changed hs94.128x64x5 to use intial T from file rather than use the
908        random number generator
909    o add infrastructure in model routines for fizhi and gridalt packages
910    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
911    o changes to permit hi-res, cubed-sphere, configuration
912      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
913      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
914      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
915        of surface winds for the cube
916      (A verification experiment, based on global_ocean.cs32x15, but with
917       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
918       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
919       complete with example surface forcing files and matlab scripts to look
920       at the output and compare it with that of global_ocean.cs32x15.)
921    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
922       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
923       to conform to the common rule.
924    o check-in the first version of the coupler + interfaces for multi-components
925       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
926       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
927       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
928       - ocean and atmos. share the same horizontal grid (no interpolation).
929       - exchanges between component and coupler is done in forward_step
930    o new verification experiment, cpl_aim+ocn:
931       coupled ocean - AIM atmosphere on cs32 grid.
932    
933    checkpoint52d_pre
934    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
935    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
936    
937    checkpoint52c_post
938    o Fixing OPTIONS files for use of exf:
939      - ALLOW_ECCO not needed
940      - ECCO_CPPOPTIONS.h should not be included from
941        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
942        as has been the case in the past
943      - All cal/exf related options are currently set in
944        single header file. Should remain so until we
945        agree on a consistent new policy.
946    o Removed all CPP options for cal package.
947      cal has no more CPP options.
948    o modified STOREs in GAD_ADVECTION
949    o corrected key comp. for passkey
950    
951    checkpoint52b_post
952    o new version: "thsice" of thermodynamic sea-ice pkg:
953     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
954     - modify fluxes but do not change theta directly;
955     - light cleaning of bulk_force pkg (still needed with thsice).
956     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
957       + output_thsice.txt to test thsice & bulk_force pkgs.
958    o put back grid & coriolis monitor output.
959    checkpoint52b_pre
960    
961    o call "do_the_model_io" at the beginning (=> dump initial state)
962    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
963    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
964      (need info on NUMBER_OF_PTRACERS)
965    o missing PTRACERS headers in some routines
966    o default tamc.h in pkg/autodiff supposed to crash
967      to ensure proper customization
968    
969    checkpoint52a_post
970    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
971      - moved surfaceTendencyTice from pkg/seaice to main code
972      - subroutine FREEZE_SURFACE now limits only surface temperature
973        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
974        => new output.txt for global_ocean.cs32x15 & global_with_exf
975      - keep the old version of FREEZE for backward compatibility;
976        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
977      - corresponding modifs for TAF directives
978    o added surface flux output variables to TIMEAVE_STATVARS
979    o time-averaged output for pkg/ptracers
980    o fix problem with ECCO-related divided adjoint

983    
984    checkpoint52a_pre
985    o some bug fixes for #undef REAL4_IS_SLOW
986    
987    checkpoint52 = ecco_c52_e35
988    o after testing adjoints of checkpoint51u_post
989    
990    checkpoint51u_post
991    o this is the post-merge tag of the ecco-branch
992      (needs another clean checkout and re-testing)
993    o various natl_box_adjoint configs and results
994      but no input fields
995    o obcs adjoint not yet merged!
996    o adding ECCO global 1x1 and 2x2 degree configs
997    o updated/extended some store directives for seaice
998    o pkg/ecco now containes ecco-specific part of cost function
999    o top level routines the_main_loop, forward_step
1000      supersede those in model/src/
1001      previous input data.cost now in data.ecco
1002      (new namelist ecco_cost_nml)
1003    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1004    
1005    checkpoint51t_post
1006    o this is the pre-merge tag of the ecco-branch
1007    
1008    checkpoint51s_post
1009    o cleanup: removed various obsolete #define-s
1010    o pkg/grdchk
1011      - renamed 'ph-grd 3' to 'grad-res'
1012      - merged from ecco-branch
1013        (remaining bug fixes for obcs gradient checks)
1014      - additional high-precision output for testreport
1015        (grep for 'precision_grdchk_result')
1016    
1017    checkpoint51r_post
1018    o cleaned up or removed CPP_OPTIONS.h files
1019    o updated results for some of the tests to reflect the new
1020      optfiles (-ieee: -O0 instead of -O3)
1021    
1022    checkpoint51q_post
1023    o cd_code:
1024      - moved cd_scheme.F -> cd_code_scheme.F
1025      - separate read_checkpoint from cd_code_ini_vars.F
1026      - separated cd_code part from write_checkpoint
1027      - updated AD_SOURCE, generated .flow
1028      - added CD_CODE_VARS.h to the_main_loop
1029      - Moving cd_code specific store dir.s to pkg/cd_code
1030    o ctrl package totally restructured
1031      - pack/unpack now optional and decoupled from
1032        xx_/adxx_ I/O
1033      - ctrl_pack/unpack cleaned
1034        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1035      - confined inclusion of AD_CONFIG.h to where necessary.
1036    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1037    
1038    checkpoint51p_post
1039    o create initial cd_code package
1040      - WARNING: the initialization of fields within packages
1041        is broken because INI_FIELDS (where READ_CHECKPOINT is
1042        called) is called *before* PACKAGES_INIT_VARIABLES.
1043        This seems to be backwards since
1044        1) its important to initially zero the entire field including
1045           the "halo" region
1046        2) zeroing needs to be done *before* reading pickup info
1047           and the pickup call might or might not happen in any
1048           particular run
1049      - this needs an overhaul for R2
1050    o cleanup verification/*/code/GMREDI_OPTIONS.h
1051    o cleanup testreport
1052    
1053    checkpoint51o_post

1060    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1061    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1062    o bug fix in find_alpha.F for MDJWF:
1063      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1064        change rho -> rho-rhoConst
1065      - replace call find_rho to find_rhonum
1066    o initialisation of rFlx extended to full array (required by TAF)
1067      and shifted to thermodynamics
1068    o removed PTRACERS.h in ptracers routine
1069    o added surfacetendencyPtr to S/R parameter list pracers_forcing

1080     o removed tools/genmake since it no longer works
1081    
1082    checkpoint51n_post
1083    o modifications to make FREEZE flux visible to pkg/kpp
1084      - moved surfaceTendencyTice from pkg/seaice to main code
1085      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1086      - subroutine FREEZE now limits only surface temperature
1087        (this means new output.txt for global_ocean.90x40x15,
1088         global_ocean.cs32x15, and global_with_exf)
1089    o added surface flux output variables to TIMEAVE_STATVARS
1090    
1091    checkpoint51n_pre
1092    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

1112    checkpoint51l_pre
1113    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
1114    o enable to apply restoring on S & T only in a latitude band.
1115    o update output (external_forcing_surf modif. change truncation errors)
1116       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
1117    
1118    checkpoint51k_post
1119    o change default to: useNHMTerms=.FALSE.
1120     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):

1136    o heckpoint_lev?_directives.h now include
1137      pkg-specific directives, whenever those are enabled.
1138    o Moving pkg-specific flow directives to corresponding pkg
1139      Moving pkg-specific differentiation list to corresponding pkg
1140      Moving pkg-specific checkpoint-lev storing to corresponding pkg
1141      ---> conventions are
1142           - pkg_ad.flow
1143           - pkg_ad_diff.list
1144           - pkg_ad_check_lev?_dir.h
1145    
1146    checkpoint51i_post

1178    o Added on-the-fly spatial interpolation capability
1179        "USE_EXF_INTERPOLATION" to pkg/exf.
1180      - This is a temporary Cartesian-grid hack until
1181        the super-duper ESMF coupler becomes available.
1182      - See verification/global_with_exf/README for usage example.
1183      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
1184        flags and modified pkg/seaice accordingly.
1185    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
1186        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
1187        non-local transport term.
1188    
1189    checkpoint51e_post
1190    o pkg/mom_vecinv:
1191      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)

1197    o AIM : add stratospheric drag in the upper level
1198    
1199    checkpoint51d_post
1200    o change function ILNBLNK (=> last non-blank char.) to return zero
1201      (instead of the string length) when the string. char is empty
1202    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
1203    o modif's to restore TAMC compatibility
1204      - avoid "_d" constructs in PARAMETER declarations
1205      - avoid interrupting lines by comment lines
1206    o Use cluster local disks for purely local I/O
1207      vs. globally visible disks needed for ctrl stuff
1208      (merged from ecco-branch)
1209      - new active_file_loc... and mdsio_..._loc routines
1210      - affected packages: autodiff, ctrl, grdchk, mdsio
1211    
1212    checkpoint51c_post
1213    o introducing integer flag debugLevel
1214      - debLevZero: suppress all output
1215      - debLevA: standard
1216      - debLevB: equivalent to current debugMode=.TRUE.
1217    o introducing pathname variable mdsioLocalDir for mdsio
1218      that can be specified at runtime
1219      (relevant for cluster I/O to local disk)
1220    `
1221    >>>checkpoint51b_post
1222    adjoint of ptracers
1223    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1224    o extended state in checkpoint_lev?, etc.
1225    o alternative ctrl/cost with tr1 or ptracer
1226    o new comlev1_bibj_ptracers
1227    o new ptracers.flow
1228    o made ptracers_forcing same as external_forcing_s
1229    o added verification for adjoint with ptracers
1230      - adm. grdchk fail so far
1231      - tlm. grdchk OK
1232      - checked tapelev/comlev recomputations: OK
1233    <<<checkpoint51b_pre
1234    
1235    checkpoint51a_post
1236    o added code for biogeochemistry package
1237      - new pkgs: dic, gchem
1238      - new subroutine in ptracers
1239    o modify code for biogeo packages
1240      - in model/src and pkg/ptracers
1241    
1242    checkpoint51
1243    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1244      - autodiff, ctrl, exf, grdchk, seaice
1245      kept separate packages
1246      - cost, ecco, obcs
1247    o updating verification/internal_wave, verification/lab_sea
1248      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1249    
1250    checkpoint50i_post
1251    o Preparing next differentiable checkpoint and sync
1252      of MAIN vs. ecco-branch
1253      - 1st step: this one is differentiable
1254      - 2nd step: next(! not this) checkpoint will have updated packages
1255                  from ecco-branch)
1256    
1257    checkpoint50h_post
1258    o new package "land": provide surface BC for AIM.
1259    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1260    o AIM: use true log-P extrapolation for near surface temp (= as in
1261        F.Molteni paper) ; update aim.5l_cs output.
1262    o New variable in PARM03 for more flexible pickups
1263    o somewhat cleaned package initialisation sequence for
1264      ctrl/ cost/ ecco/ in packages_... routines
1265    
1266    checkpoint50g_post
1267    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1268      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1269      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1270        made the default because of faster convergence than ADI
1271    
1272    checkpoint50f_post
1273    o exf totally restructured
1274      - replaced all exf_set_ routines by one generic exf_set_gen.F
1275        and made sure it's still differentiable
1276      - split exf_getffields.F into new exf_bulkformulae.F
1277      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1278      - updated adjoint/makefile and relevant verif. accordingly
1279    
1280    checkpoint50f_pre

1288     o removed lots of single quotes from comments
1289    
1290    checkpoint50e_post
1291    o make KPP work with PTRACERS
1292     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1293       nearly a copy of kpp_transport_s
1294     - there is no analogue to SurfaceTendencyS, so I have to use
1295       gPtr(of the surface layer) instead
1296    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1297    checkpoint50e_pre
1298    
1299    checkpoint50d_post
1300    o change kpp output from multiple-record state files to single-record state
1301      files analogous to write_state.F
1302    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1303      analogous to the cg2d-related output.
1304    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1305      so that writing to internal file fn (with length 512) fails.
1306    checkpoint50d_pre
1307    
1308    checkpoint50c_post
1309    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1310    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1311    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1312    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1313    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1314    
1315    checkpoint50c_pre
1316    Merging from release1_p13:
1317    o bug fix for pkg/seaice dynamic solver
1318    o Added SEAICE_initialHEFF to pkg/seaice
1319    
1320    checkpoint50b_post
1321    o store u*,v* in gU,V instead of in guNm1,gvNm1
1322    o in order to put the momForcing out of the Adams-Bashforth:
1323      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1324      to timestep.F
1325    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1326    o re-generate output for highly sensitive test-exp:
1327       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1328    
1329    checkpoint50b_pre
1330    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1331    o corrected CPP option mismatch in exf_Bulk... functions for case
1332      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1333    
1334    checkpoint50a_post
1335    o Bug fix for merging between c50 and KPP.
1336      ikey was passed from thermodynamics to kpp_calc via
1337      common block rather than being recomputed in kpp_calc,
1338      in contradiction with new key itdkey.
1339      New key ikppkey created, and tamc.h headers updated.
1340    
1341    checkpoint50
1342    - 2nd step of merge with ecco-branch:
1343      merge changes in ecco-branch back into main trunk
1344    - bug fix in find_alpha
1345    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1346    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1347    - merged some sliced AD support routines
1348    
1349    checkpoint49
1350    merged from ecco-branch:
1351    o exf:
1352      - Enable initialisation of forcing fields to constant
1353        (runtime) values.
1354      - in exf_getffields.F
1355        Reduce i-/j-loop to interior domain, discarding overlaps.
1356        That also fixes wrong TAF-key computations for key_1, key_2
1357        with bulf formulae.
1358      - exf_init.F modify #ifdef for exf_init_evap
1359      - exf_getffieldrec.F, ctrl_getrec.F
1360        The following INT-usages are not safe:
1361          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1362          fldcount = int(fldsecs/fldperiod) + 1
1363        and were modified.
1364    o autodiff: checkpoint_lev...
1365      - updated storing for bulk formulae (some arrays were missing)
1366      - added state for seaice package
1367      - synchronized with main branch
1368    o DIVA:
1369      Modif.s in
1370      - the_main_loop.F
1371      - the_model_main.F
1372      and added cost_final_restore.F cost_final_store.F
1373      o With these changes, it is possible to fully separate
1374        the first forward run to compute the cost function (mdthe_main_loop)
1375        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1376        into separate model executions.
1377        This enables better tuning of DIVA to given queue sizes.
1378      o Loss of cost function value in consecutive DIVA runs is
1379        fixed by storing to 'costfinal' file.
1380      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1381        beginning/end of adjoint integration is accounted for.
1382      The current changes apply to TAF-1.4.26.
1383      TAF has one remaining bug, requiring one manual change
1384      (see MITgcm manual).
1385    o cal: synchronized between MAIN and ecco-branch
1386    
1387    checkpoint48i_post
1388    o Changes to restore differentiability of code w.r.t. previous tag
1389      (mostly adding new routines to make list and replacing
1390      pressure by totPhiHyd).
1391    o Updated and merged grdchk package
1392      - has both ADM and TLM checks
1393      - works for single- and multi-proc.
1394      - output cleaned
1395      - worked successfully for parallel DIVA
1396    o genmake:
1397      - Adding -platform=SP4
1398      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1399    o Modif. for DIVA:
1400      ctrl_unpack should not be called in intermediate DIVA interval.
1401      (similar thing would apply for active files such as
1402      tbar, sbar, psbar, which should not be reinitialised;
1403      only relevant for ecco-branch)
1404    
1405    checkpoint48h_post
1406    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1407    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1408    o Added SEAICE_initialHEFF to pkg/seaice
1409    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1410    
1411    checkpoint48g_post
1412    --- EOS:
1413    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1414      store total Potential in totPhyHyd for diagnostics & EOS.
1415    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1416    --- Pressure/geopotential gradient:
1417    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1418    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1419      ( changes results of global_ocean_pressure )
1420    o NLFS + z-coord.: add eta*Rho' contribution.
1421    o accurate phiHyd when using interface-W at the middle between 2 centers
1422     ( changes results of ideal_2D_oce )
1423    o includes r* 2nd term in potential gradient.
1424    
1425    checkpoint48f_post
1426    Merging from release1_p12:
1427    o Modifications for using pkg/exf with pkg/seaice
1428      - improved description of the various forcing configurations
1429      - added basic radiation bulk formulae to pkg/exf
1430      - units/sign fix for evap computation in exf_getffields.F
1431      - updated verification/global_with_exf/results/output.txt
1432    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1433      (SBO) core products, including oceanic mass, center-of-mass,
1434      angular, and bottom pressure (see pkg/sbo/README.sbo).
1435    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1436      to avoid negative values in shallow regions.
1437      - updated verification/natl_box/results/output.txt
1438      - updated verification/lab_sea/results/output.txt
1439    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1440    o Added useSingleCpuIO option (see PARAMS.h).
1441    o Updated useSingleCpuIO option in mdsio_writefield.F to
1442      work with multi-field files, e.g., for single-file pickup.
1443    o pkg/seaice:
1444      - bug fix in growth.F: QNET for no shortwave case
1445      - added HeffFile for specifying initial sea-ice thickness
1446      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1447    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1448      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1449    o pkg/seaice:
1450      - adjoint-friendly modifications
1451      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1452    
1453    checkpoint48e_post
1454    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1455    o dynamics: change definition of computational domain & adapt mom_fluxform
1456      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1457    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1458        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1459        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1460        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1461        inverted_barometer solid-body.cs-32x32x1
1462      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1463    
1464    checkpoint48d_post
1465    o in preparation for r*:
1466     a) use pre-computed gradient of hydrostatic potential:
1467        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1468     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1469        => affects results of glob_oce_pressure (different truncation error)  
1470      update output.txt of ideal_2D_oce & global_ocean_pressure
1471    
1472    checkpoint48d_pre
1473    o in preparation for r*:
1474      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1475      pass the 2 comp. of the grad. as arguments to momentum S/R.
1476      but for the moment, only used if it does not change the results.
1477    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1478    
1479    checkpoint48c_post
1480    Modifications in treatment of initial flux forcing controls
1481    to avoid extra storing of flux fields.
1482    
1483    checkpoint48c_pre
1484    o Added tidal_basin_2d experiment (currently 1D!)
1485    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1486    
1487    checkpoint48b_post
1488    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1489     (modification to pressure gradient not yet implemented)
1490    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1491      (for U & V) that are used for vertical advection of momentum.
1492    
1493    checkpoint48a_post
1494    o In preparation for r*, use temp. array to compute vertical transport
1495       in flux-form momentum pkg. => change results of few test-exp.
1496      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1497                        lab_sea, natl_box & plume_on_slope
1498    
1499    checkpoint48
1500    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1501    
1502    checkpoint47j_post
1503    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1504    o moved adexch from forward_step to addummy_in_stepping
1505    o added exch in ctrl_map_...
1506    o aveFreq.=0. at end of cost_final to avoid overwrite in
1507      reverse checkpointing loop
1508    o Yet more changes in gmredi:
1509      * adgmredi_calc_tensor
1510        avoiding all recomputation of gmredi_slope_limit
1511      * adgmredi_x/y/rtransport
1512        added flag for excessive storing to avoid recomp. of
1513        u/v/rtans, dTdx/y/z
1514        -> this is not really necessary and very memory-consuming
1515      * adgmredi_slope_psi:
1516        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1517      * gmredi_slope_limit
1518        re-activated full calculation of taperfct for case 'ac02'
1519    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1520    
1521    checkpoint47i_post
1522    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1523    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1524      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1525    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1526    o gmredi: fix few bugs.
1527    
1528    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1529    This will be a good checkpoint to plug into the ecco-branch.
1530    o few modif.'s to get latest version adjointed
1531      (mainly kick out code in ini_linear_phisurf)
1532    o modif's to run adjoint with exactConserv
1533    o case GM_BOLUS_ADVEC should be cleaned
1534      S/R gmredi_slope_psi should be cleaned
1535    o verification/carbon now has exactConserv=.TRUE.
1536    
1537    checkpoint47g_post
1538    o time-average AIM output: becomes independent from statvars time-average
1539      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1540    o After TAF bug fix:
1541      Tested adjoint of gmredi package.
1542      Tests were done with checkpoint47 rather than with latest
1543      checkpoint47f_post since the latter is broken for the adjoint
1544      verification/carbon/ contains both ADM and TLM gradient checks.
1545    Here they are, before they get changed/lost/stolen.
1546    Mostly modif.'s to fix numerical sensitivities.
1547    Gradient checks OK for
1548    - GM_taper_scheme:
1549      * clipping
1550      * ac02
1551      * linear
1552      * glw91
1553      * dm95
1554      * ldd97

1570      - usage examples are Experiments 8 and 9 in
1571        verification/lab_sea/README
1572      - verification/lab_sea default experiment now uses
1573        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1574    
1575    checkpoint47e_post
1576    o created a tag prior to creating a branch
1577    
1578    checkpoint47d_post
1579    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1580      at the bottom boundary had an erroneous half slip boundary condition
1581    o added bottom drag and no slip boundary condition capabilities to
1582      oceanic pressure coordinates code
1583    o added new verification experiment global_ocean_pressure, this experiment is
1584      also described in the tutorial section of the manual
1585    checkpoint47d_pre
1586    
1587    checkpoint47c_post
1588    o Added a verification experiment for a global cubed-sphere ocean run
1589      -  verification/global_ocean.cubed32x32x30
1590      -  uses pkg/therm_seaice and pkg/bulk_forcing
1591    
1592    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1593    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1594      when using P-coordinate; only implemented for atmospheric config.
1595    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1596      NOTES: requires option NONLIN_FRSURF to be "#define".
1597    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1598    
1599    checkpoint47b_post
1600    Merging from release1_p9:
1601    o pkg/seaice
1602      - removed GOTO's and added taf directives
1603      - double precision constants to reduce the g77 (Linux)
1604        to F77 (SGI) differences reported in release1_p8
1605    o tools/genmake
1606      - added SGI options
1607    o verification/testscript
1608      - updated to that of checkpoint47a_post
1609    o verification/global_ocean.90x40x15/input/eedata
1610      - modified for SGI f77 compatibility
1611    o verification/lab_sea
1612      - added description of sea-ice model
1613      - added missing matlab routines
1614      - added test of thermodynamics parallelization
1615    
1616    checkpoint47a_post
1617    o new pkg: aim_v23
1618     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1619       for now, keep the same surface forcing as before.
1620     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1621     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1622     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1623    o add diagnostic of surface correction term in monitor output
1624    
1625    o bulk_force and therm_seaice
1626    - Two packages:  bulk_force (Bulk forcing)
1627      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1628    - Earlier integration from Stephaine Dutkiewicz
1629      and Patrick Heimbach.
1630    - Two ifdef statements for compile time,
1631       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1632    
1633    checkpoint47
1634    differentiable version of checkpoint46n_post
1635    o bug fix in quasihydrostaticterms
1636    o * "clean" adjoint code (in terms of extensive recomputations)
1637        can now be obtained for all GMREDI options (i.e. for
1638        - GM_VISBECK_VARIABLE_K
1639        - GM_NON_UNITY_DIAGONAL
1640        - GM_EXTRA_DIAGONAL
1641        - GM_BOLUS_ADVEC )
1642      * However, wrong gradient check problem remains unsolved.
1643      * New CPP options have been introduced for different
1644        tapering schemes
1645    o external_fields_load now part of differentiation list
1646    o pressure needs multiple storing;
1647      would be nice to have store_pressure at beginning or
1648      end of forward_step, e.g. by having phiHyd global (5-dim.)
1649      (NB: pressure is needed for certain cases in find_rho,
1650      which is also invoked through convective_adjustment).
1651    o recomputations in find_rho for cases
1652     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1653    o #define ATMOSPHERIC_LOADING should be differentiable
1654    o ini_forcing shifted to begining of initialise_varia
1655    o Incorporating QNVS line search routines into MITgcm
1656      (this is separate code, and therefore not under pkg)
1657      lsopt/, optim/
1658    o Updated verification/carbon/
1659      - #define GM_VISBECK_VARIABLE_K
1660      - GM_taper_scheme    = 'ldd97'    
1661    
1662    checkpoint46n_post
1663    Merging from release1_p8:
1664    o verification/natl_box:
1665      updating new external_fields_load routine
1666    o New package: pkg/seaice
1667      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1668      The sea-ice code is based on Hibler (1979-1980).
1669      Two sea-ice dynamic solvers, ADI and LSR, are included.
1670      In addition to computing prognostic sea-ice variables and diagnosing
1671      the forcing/external data fields that drive the ocean model,
1672      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1673      The implied surface heat flux is then stored in variable
1674      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1675      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1676      non-local transport term.  Because this call precedes model
1677      thermodynamics, temperature under sea-ice may not be "exactly" at
1678      the freezing point by the time theta is dumped or time-averaged.
1679      N.B.: fairly large differences in accuracy occur across
1680            different platforms/compilers; comparison between
1681            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1682            generated output gives:
1683       T           S           U           V
1684      C D M    c        m  s        m  s        m  s        m  s

1688    
1689      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1690    o GAD:
1691      - generated new common blocks to account for call of
1692        same gad routines with differing traceridentities
1693        (needed to modify tracerIdentity indices in GAD.h)
1694      - generated separate common blocks for case useCubedSphereExchange
1695        (Department of Futurology)
1696      - parameter lists to gmredi_?transport: added tracerIdentity
1697      - added new key indices to tamc.h
1698    o external_fields_load:
1699      - added this routine to TAF list
1700      - needed to make some common blocks global and additional storing
1701        along the same lines as exf package (checkpoint_lev?_directives.h)
1702    o exf:
1703      updated external forcing package
1704      - bug fixes carried over from ecco-branch
1705        (missing OBCS_OPTIONS.h in two routines)
1706      - enable easy to use "no forcing".
1707      - added exf I/O for atmospheric loading
1708      - added exf I/O for runoff data
1709      - transfered scaling between exf <-> MITgcm to exf namelist
1710    o Adding new verification experiment global_with_exf.
1711      This verification experiment is almost identical to the
1712      global_ocean.90x40x15 experiment, except that it uses
1713      the exf (and cal) package instead of the
1714      external_fields_load routine (cf README file).
1715    
1716    checkpoint46m_post
1717    o modified testscript to return -- when there are no lines of "%MON" output
1718    o added new flag "quasiHydrostatic" for QH mode
1719      and new routine quasihydrostaticterms()
1720    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1721      New routine: mom_u_coriolis_nh()
1722    o fixed sign of non-hydrostatic metric terms in u and v equations.
1723      Depend on correct sign of gravitySign.
1724    o added work.pc* to .cvsignore in aim directories using ifc
1725    o introduced flag for controllin non-hydrostatic metric terms
1726    o removed gravitySign from PARM04
1727    o switched to g77/ifc from pgf77 in aim experiments
1728    
1729    checkpoint46l_post
1730    o made convective adjustment work with pressure coordinates:
1731     - changed the direction of k-loop in convective_adjustment.F for the
1732       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1733     - adjusted the reference pressure k-index in convective_adjustment.F
1734     - adjusted the convection condition in convect.F (in analogy to
1735       calc_ivdc.F)
1736     - convective_adjustment no longer computes anything on the halos
1737     - removed the warnings about negative salinity from find_rho.F and
1738       find_alpha.F; instead the new routine look_for_neg_salinity, called
1739       at the beginning of find_rho, find_alpha, and find_beta, does a
1740       check of the entire slice, if CPP-option
1741       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1742    checkpoint46l_pre
1743    
1744    checkpoint46k_post
1745    o fixed the verification/global_ocean.90x40x15 experiment:
1746     - new bathymetry (the world according to A., JMC, and M.)
1747     - new initial fields and forcing fields (*.bin files)
1748     - new POLY3.COEFFS (for the next release one should switch to a full
1749       equation of state: JMD95P or MDJWF)
1750     - fixed several errors and redundancies in the data file
1751     - experiment uses looped cells
1752     - added matlab directory with diagnostic scripts for plotting of output
1753    
1754    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1755     - read AIM physics parameters from a file (data.aimphys)
1756     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1757    
1758    checkpoint46j_post
1759    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1760    o move wVel computation at the end of the time step, in S/R integr_continuity
1761    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1762    o update timeave pkg for wVel diagnostic.
1763    checkpoint46j_pre
1764    
1765    checkpoint46i_post
1766    o Clean up AIM package (and keep the results unchanged):
1767      include CPP_OPTION and use IMPLICT NONE in all routines ;
1768      declare all the variables _RL ; use _d 0 for all numerical constants.
1769      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1770    
1771    checkpoint46h_post
1772    o cleaned up the use of rhoNil and rhoConst.
1773      - rhoNil should only appear in the LINEAR equation of state, everywhere
1774        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1775        and the dynamical equations are all divided by rhoConst
1776    o introduced new parameter rhoConstFresh, a reference density of fresh
1777      water, to remove the fresh water flux's dependence on rhoNil. The default
1778      value is 999.8 kg/m^3
1779    o cleanup up external_forcing.F and external_forcing_surf.F
1780      - can now be used by both OCEANIC and OCEANICP
1781    checkpoint46h_pre
1782    
1783     Added code to convert surface volume flux (fresh water) into
1784     a mass flux when using P coordinates in the ocean (OCEANICP).
1785     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1786    
1787    checkpoint46g_post
1788    o Include a new diagnostic variable phiHydLow for the ocean model
1789      - in z-coordinates, it is the bottom pressure anomaly
1790      - in p-coordinates, it is the sea surface elevation
1791      - in both cases, these variable have global drift, reflecting the mass
1792        drift in z-coordinates and the volume drift in p-coordinates
1793      - included time averaging for phiHydLow, be aware of the drift!
1794    o depth-dependent computation of Bo_surf for pressure coordinates
1795      in the ocean (buoyancyRelation='OCEANICP')
1796      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1797        Theta, Salinity, and Pressure in the parameter list. This routine is
1798        presently contained in find_rho.F. This routine does not give the
1799        correct density for 'POLY3', which would be a z-dependent reference
1800        density.
1801    o cleaned up find_rho
1802      - removed obsolete 'eqn' from the parameter list.
1803    o added two new verification experiments: gop and goz
1804      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1805    checkpoint46g_pre
1806    
1807    checkpoint46f_post
1808    o Enable tangent linear (forward mode) gradient checks:
1809      - extended active file handling to g_... files
1810      - added TANGENT_SIMULATION to theSimulationMode
1811      - extended grdchk package accordingly
1812    o added tangent linear setup in verification/carbon/code_ftl
1813    o added adjoint setup in verification/front_relax/code_ad
1814    
1815    checkpoint46e_post
1816    o Added new equation of state -> MDJWF
1817      - EOS of McDougall et al., 2002, JAOT, submitted
1818      - caveat: the equation of state is only valid for a smaller (more
1819        realistic?) range of values than JMD95P/Z and UNESCO
1820      - added masks to the calculation of pressure in store_pressure
1821      - added more check values for density in check_eos (ini_eos.F), some of
1822        the old check values are out of the range of the MDJWF-eos, so don't
1823        expect perfect matches for those
1824    checkpoint46e_pre
1825    
1826    checkpoint46d_post
1827    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1828      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1829      case of pressure coordinates. eosType='JMD95Z' in
1830      combination with buoyancyRelation='OCEANICP' now causes an error.
1831    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1832      in find_alpha/beta.
1833    checkpoint46d_pre
1834    
1835    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1836      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1837    
1838    checkpoint46c_post
1839    o Changes necessary for ocean in p-coordinates
1840     -  Added new buoyancy relation = 'OCEANICP'
1841     -  Added new parameters = gravitySign (this used to be contained inside
1842        the factor dRdZ which I added when we first switched to R coordinates).
1843     X GM/Redi is not compatible (yet)
1844     X bottom drag and no-slip need to be debugged.
1845    checkpoint46c_pre
1846    
1847    checkpoint46b_post
1848    o Added new equation of state -> JMD95Z and JMD95P
1849      - EOS of Jackett and McDougall, 1995, JAOT
1850      - moved all EOS parameters into EOS.h
1851      - new routines ini_eos.F, store_pressure.F
1852    o Added UNESCO EOS, but not recommended because it requires
1853      in-situ temperature (see JMD95)
1854    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1855      unesco.f to be used with POLY3
1856    checkpoint46b_pre
1857    
1858    checkpoint46a_post
1859    o Added (atmospheric) pressure loading
1860      - new field in FFIELDS.h, etc...
1861      - new cpp flag ATMOSPHERIC_LOADING
1862    o Changed hFacC to _hFacC in calc_phi_hyd.F
1863    o Added SHORTWAVE_HEATING to some files for consistency
1864    checkpoint46a_pre
1865    
1866    checkpoint46
1867    further merges from release1_p5
1868    o new ctrl package
1869      - adopted from ECCO environment to enable optimization
1870      - added Eliassen Palm fluxes to controls
1871    o added Eliassen Palm flux controls to gradient check package
1872    o cost package
1873      - Compatible with new ctrl package
1874      - added Eliassen Palm cost hooks
1875      - modif's of existing cost functions
1876    o Adjoint-related bug fixes in kpp:
1877      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1878      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1879    o autodiff package
1880      - flow directives:
1881        + new for S/R do_the_model_io
1882        + enhanced for S/R checkpoint
1883        + new gmredi.flow
1884      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1885        disable adcommon.h/g_common.h by default.
1886      - fixed problem for adjoint of global_max
1887    o modified verification/carbon/
1888    o New setup for adjoint of global_ocean
1889    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1890    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1891    o incorporated hooks for sponge layer code (external_forcing.F)
1892    
1893    checkpoint45d_post
1894    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1895    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1896      (affects plume_on_slope "cg2d" output)
1897    o add new parameter deltaTfreesurf for free-surface time stepping
1898    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1899  o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B  o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1900  o change phiMin in exp1 (to agree with documentation)  o change phiMin in exp1 (to agree with documentation)
