5      ==============================      ==============================
6    
7    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
8      Needed for high-res. runs with large global files
9      to be able to limit tapelev size
10    o Changed some tests for adjoint:
11      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
12      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
13      * global_ocean.90x40x15/ back to default 3-level checkpointing
14    
15    checkpoint57p_post
16    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
17    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
18      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
19    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
20    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
21      (was already the case for dissipation with mom_vecinv,
22       and also the case for grad.PhiHyd when staggered-timeStep)
23      This will allow to put dissipation out-off the AB time-stepping.
24     Unfortunately, affects truncation error. Update output of exp. that "fails"
25      (cg2d matching number) and leave the others for later: front_relax(10),
26      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
27      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
28    
29    checkpoint57o_post
30    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
31      (2) its ready to be documented during the 20050801 DocFest
32    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
33      for ideal_2D_oce and lab_sea on linux_ia32_g77
34    o set to #undef CTRL_SET_OLD_MAXCVARS_30
35      in global1x1_tot/code_seaice_adj to access indices 32, 33
36      (worth another tag)
37    
38    checkpoint57n_post
39    o adding precip control xx_precip 32
40    o adding swflux control xx_swflux 33
41    o Replacing 10 forcing penalty cost routines by 1 generic.
42    o Implementing partitioning in time-mean and variable adjustment
43      for atmos. state.
44    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
45    o in natl_box_adjoint:
46      * updated exp 1 to 10
47        (but does not have time-mean vs. variable split results yet)
48    o updated global1x1/*_seaice_adj/
49      to incorporate latest changes
50    o enable useSingleCpuIO for mdsio vector routines
51      (applies in particular to tapelev I/O)
52    o removed inefficient K-loop in all active_file*control*.F
53    
54    checkpoint57m_post
55    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
56      and advect_cs (use EXCH-2 and standard cs-32 grid files).
57    o pkg/exch2: filling of face-corner halo regions is optional
58      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
59    
60    checkpoint57l_post
61     tag before updating tutorials (pre-release-2)
62    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
63       for output and interpolation of input fields onto model grid)
64    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
65       Affects results of exp. rotating_tank ; update output.txt.
66    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
67          and taking the square quantity and/or using a fraction-weight field.
68    o fix aim_diagnostics_init.F mate numbers.
69    o add mnc output capability to diagnostics/diagstat and update
70      our cvsignore files for the ACSII output generated
71    
72    checkpoint57k_post
73    o lab_sea now uses diagnostics package and provides a suite of
74      new EXF diagnostics output.
75    
76    checkpoint57j_post
77    o exf
78      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
79        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
80        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
81      * extended diagnostics output
82        - now includes all EXF variables
83        - hs, hl moved to common block
84        - separate S/R for diagnostics, called after ctrl vector is added
85        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
86        - EXFqnet contains true Qnet (i.e. includes qsw)
87      * updated verif. lab_sea, global_with_exf
88      * Rearranging hflux (exf_mapfields -> exf_getforcing)
89        to ensure that diagnostics sees a true EXFqnet
90    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
91    o diagnostics pkg: change pointers so that 1 diagnostic can be used
92      several times with different frequencies.
93    o mnc-ify the thsice package as requested by Daniel Enderton
94      - the monitor--MNC output needs work
95      - many attributes need to be added (most are currently blank)
96    o mnc-ify theaim_v23 package as requested by Daniel Enderton
97      - many attributes need to be added (most are currently blank)
98    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
99    o add Sadourny like discretization to the 4th.O vorticity advection scheme
100    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
101      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
102         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
103    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
104     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
105    
106    checkpoint57i_post
107    o Diagnostics package was changed: diagnostic allocation is now deactivated
108      by setting an empty file name in the namelist (used to be by setting 0 frequency)
109    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
110      add 1rst Order upwind vertical Shear.
111    o add a quick fix for A/B checkpointing in OFFLINE mode
112    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
113      end-run around the C/Fortran linking horror in eesup/src/timers.F
114    o added pkg/runclock: allows user to terminate run based on wall clock
115    o added non-hydrostatic scaling parameter: nh_am2
116    o pkg/my82: futile attempt to make results compiler-independent by adding
117      some "_d 0", etc. no effect.
118    o for mnc output, fill the 'T' coordinate var with myTime and create a
119      separate 'iter' variable for iteration count
120    o pkg/diagnostics:
121      add new capability: output of Global/Regional & per-level statistics ;
122      tested against monitor output (including land & thSIce) on various exp.
123    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
124    
125    checkpoint57h_done
126      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
127      data.diagnostics, data.gchem, data.ptracers) is done.
128    
129    o pkg/diagnostics: prepare for Global/Regional statistics.
130      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
131    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
132      and rename it: DIFFERENT_MULTIPLE
133    
134    checkpoint57h_post
135    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
136    o pkg/diagnostics: change output frequency, now in seconds (instead
137      of Nb of iterations). This requires to change data.diagnostics.
138    checkpoint57h_pre
139    
140    o in mnc, let the user create the output dir if both mnc_outdir_date
141      and mnc_outdir_num are false
142    o add fflags() to pkg/diagnostics which allows one to specify, on a
143      per-file basis, the file precision [default behavior is unchanged]
144    o added diagnostics to pkg/kpp, including computation of mixed layer
145      depth based on a temperature/density criterion
146    o updated verification/natl_box to test the new pkg/kpp diagnostics
147    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
148    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
149    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
150      not mnc -- this mistake was found by JMC and is now corrected
151    
152    checkpoint57g_post
153    o add Adams-Bashforth 3rd Order time stepping:
154      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
155      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
156    checkpoint57g_pre
157    
158    o make lambda[Theta,Salt]ClimRelax spatially varying
159      (default remains spatially uniform constant based on tau)
160    o added new control variables
161      * init. uVel, vVel, etanN
162      * lambda[Theta,Salt]ClimRelax
163    o separate masks used for ctrl_pack/unpack 'from write_grid' output
164      (suggested by G. Forget)
165    
166    checkpoint57f_post
167    o add parameter "baseTime" = model base time = time at iteration zero
168      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
169      account for baseTime shift
170    o move Coriolis arrays from PARAMS.h to GRID.h
171    checkpoint57f_pre
172    
173    o mnc-ifying the seaice package
174    o introduced an alternative length scale calculation for use in the limiting
175      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
176    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
177    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
178      as well as grad(vort3).  Made it compatible with both approximate form
179      for the cubed sphere and full form of these gradients.  Added flag
180      useFullLeith to select between approximate and full form.  
181    o add "d0" in getcon.F to reduce differences between compilers/platforms
182      update output.txt of exp. fizhi-gridalt-hs
183    o change port_rand funtion to allow to set the seed.
184    o fix obscure MNC bug involving conversion between reals and integers
185      - it caused no problems with certain (eg. gcc, ifc) compilers but the
186        new version is now more standards-compliant
187    o adjoint-related modifications
188      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
189      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
190      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
191    
192    checkpoint57e_post
193    o Adding eddy stress controls a la Ferreira et al.
194    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
195    
196    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
197      update output.txt of exp. fizhi-gridalt-hs
198    o add more "Z" dimensions and associated coordinate vars to MNC
199    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
200    o parameter calendarDumps: when set, approximate months (30-31 days) and years
201      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
202      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
203      months and years.  Requires pkg/cal.
204    o diagnostics: add pickup functionality
205      - off by default for backwards compatibility
206      - current version only uses MDSIO -- MNC will be added
207    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
208    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
209    
210    checkpoint57d_post
211    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
212    o modify verification/ideal_2D_oce so that it tests the creation of mnc
213      output from the diagnostics package
214    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
215    o make genmake2 more portable by using ".$FS" instead of ".f" for more
216      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
217    o add coordinate variables to the MNC output from the diagnostics package
218    o change MNC-flags default value: true when useMNC=TRUE
219    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
220      the ability (off by default) to read the grid information using MNC
221    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
222    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
223    o do snap-shot diagnostics at the middle of the time-interval (instead of
224      at the end).
225    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
226      new test for AIM with thSIce + slab-ocean
227    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
228    o move state variable diagnostics to the beginning of the time step ;
229      (note: still needs some work specially for snap-shot diagnostics)
230      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
231    
232    checkpoint57c_post
233    o Change testing option (-ieee) to get closer agreement between g77 & ifort
234    o generate new output.txt files on faulks with g77 & the new -ieee option
235    checkpoint57c_pre
236    
237    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
238      update output.txt of exp. global_ocean.90x40x15
239    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
240      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
241    o add saltFlux(+File) forcing capability with periodicExternalForcing
242    o allow to use pkg diagnostics for GM-Redi & ThSIce output
243    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
244    o improvements for the MNC output from DIAGNOSTICS:
245      - correct handling of the unlimitied dimension
246      - all dims now have associated coordinate variables
247      - variables located at U, V, and Corner ("Z") points are now written
248        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
249        *all* data points are output
250    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
251    o added pkg/seaice/seaice_monitor.F
252    o mdsio_readfield.F can now read files visible only to master MPI process.
253    o pkg/seaice: some test code for ice-modified ocean stress
254    o exf_getffields interpolation defaults to bilinear for all scalar forcing
255      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
256      spurious negative numbers for precipitation and humidity.  Will cause
257      some small numerical differences for integrations using pkg/exf/exf_interp.F.
258    o pkg/ctrl/
259      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
260        May be enabled via doPackDiag
261      *  introduce z-scaling of
262         + gradient (doZscalePack) and
263         + control (doZscaleUnpack)
264    o pkg/mdsio/
265      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
266      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
267    
268    checkpoint57b_post
269    o simplify options in diagnostics_fill arguments (remove weird combinations)
270    o fix MNC coordinate variables so that they now contain per-face index
271      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
272      general, EXCH2 grids are only aligned to a "local" coordinate system
273    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
274    o Implement instantaneous output within pkg diagnostics:
275      setting a negative frequency in data.diagnostics produces
276     "snap-shot" output (as opposed to time-average if freq > 0)
277    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
278      NOTE: change ptracer diagnostics name: use 2 characters to work with
279            more than 9 tracers. Add also diagnostics of advect & diffus flux.
280    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
281      becomes the coordinate variable for the 'T' dimension
282    o add CF-style coordinate variables to MNC
283      - just a first cut:  numbers are meaningless on the cubesphere and
284        missing along the T axis but otherwise it works!
285    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
286    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
287    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
288      this is based directly on what the model compute, so that the content of
289      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
290    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
291    o clean up build options files for SunOS, in particular
292      - remove -traditional from xmakedepend
293      - change -xarch=v9 to -xarch=native for f77
294      - restore use of make (not gmake)
295      - add CC=gcc if using g77
296    o changes per discussion of AM, JMC, & EH3 today:
297      - move redundant "grid" variables out of "state" -- in preparation of
298        creating proper CF-style coordinate variables and in recognition
299        that any/all grid variables can be easily copied (eg. w/NCO) from
300        the grid files into any of the other NetCDF files
301      - *always* output grid variables with MDSIO (this will eventually be
302        changed)
303      - output MNC grid file if useMNC is true
304    o every instance of _END_MASTER() has been found and replaced with
305      _END_MASTER( myThid ) in order to satisfy certain picky Sun
306      preprocessors
307    o re-arrange diagnostics pkg initialisation:
308     - allow each package to extend the available diagnostics list
309     - add some checking and fix small problems (multi-threaded, ...)
310     - new S/R diagnostics_fill (replace fill_diagnostics):
311       look through the short list of active diag. (instead of the long list)
312       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
313    
314    checkpoint57a_post
315    o this set of changes restores TAMC compatibility
316      tested for global_ocean.90x40x15 adjoint on trough
317      (what a pain)
318    
319    checkpoint57a_pre
320    o some modifs in tools/build_options for sunos
321    o call ctrl_pack for ctrl at end for optimcycle=0
322    
323    checkpoint57
324    o add horizontal bi-harmonic viscosity for vertical velocity
325      - new parameter viscA4W (defaults to viscA4)
326      - affects only non-hydrostatic code
327      - to be done: no-slip lateral boundary conditions
328    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
329    o implement Implicit Vertical advection for pTracers
330    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
331      (implemented also for implicit vertical diffusion & advection)
332    o OBCS: extend application of tracer open boundary conditions
333      to a strip beyond the boundary of width Olx/Oly
334    o add call monitor to TAF set of required calls (flow directives)
335      and include in natl_box_adjoint
336    o untangle a few ifdefs related to cost, ctrl, autodiff
337      untangel a few ALLOW_ECCO_OPTIMIZATION
338    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
339      (theta2, salt2 in ecco_cost_weights)
340    
341    checkpoint56c_post
342    o OBCS as control variables
343      - update ctrl_ad_diff.list, obcs_ad_diff.list
344      - remove balance of obcs controls from default
345      - fix index bug nobcs in ctrl_init
346      - fix dummy fields filen in ctrl_pack
347      - add dummy weights for obcs
348    o lsopt: comment out fort.94 output
349    o optim:
350      - remove unnecessary header files
351      - adjusted namelists
352      - add xerbla.F to Makefile
353    o exf:
354      - multiple modifications of exf_check_range
355      - unit change in exf_init_runoff from [m/year] to [m/s]
356    o mdsio:
357      - i/o-vector change debugLevel from debLevA to debLevB
358    
359    checkpoint56b_post
360    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
361      is called from DO_THE_MODEL_IO
362      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
363      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
364      - clean up PTRACERS_WRITE_TIMEAVE a little
365    o add another verification experiment that tests both the cfc-pkg and
366      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
367      reactive tendencies treated inline with regular timestepping
368    o testreport previously did a lousy job of comparing small numbers, so
369      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
370      implemented in the little c-progam tmp_cmpnum.c which is embedded in
371      testreport.
372    o ptracers_monitor: bug fix for MPI
373    
374    checkpoint56a_post
375    o GCHEM: finish reorganizating the package
376      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
377        (introduces another 3D-array for each passive tracer, but only if
378        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
379        gchemTendency is not needed because the timestep is done separately)
380      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
381      - GCHEM is now---more or less cleanly---separate from PTRACERS
382      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
383        so clear to me how that should be done in a general way.
384    o CFC: improve formatting of output in CFC_ATMOS
385    o PTRACERS:
386      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
387        that ALL experiments with ptracers enable can be checked. This makes
388        GCHEM_MONITOR obsolete.
389      - include a runtime parameter PTRACERS_monitorFreq that defaults to
390        monitorFreq
391      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
392    o add PTRACERS (PTR0[1-5]) to testreport output
393    o exf_check_range:
394      * default changed to .TRUE.
395      * will check values for niter0 if debLevA, every timestep if debLevB
396      * STOP in exf_check_range if 'out of range'
397      * range chosen generous to allow for potential extema
398      TBD: a version with stricter range
399           permitted range would be runtime parameters
400    o GMredi:
401      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
402      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
403      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
404    o GCHEM:
405      - move call to GCHEM_FORCING_SEP, so that it is now called before
406        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
407      - introduced a useGCHEM runtime flag and applied it everywhere.
408      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
409        this flag is now only visible within GCHEM-pkg routines.
410      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
411        be replaced by a 3D array that is computed before thermodynamics; for
412        this, the tracer ID iTracer had to be included into the parameter list
413        of ptracers_forcing
414      - set up forward_step to call gchem_forcing, that will replace
415        gchem_forcing_int in ptracers_forcing
416      - cleaning up
417    o small cleaning of exch2: remove files that are also in eesupp/src
418    
419    checkpoint56
420    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
421    o mnc: cleanup "full" files--fixes out-of-memory problem
422    o ECCO-GODAE
423      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
424      * fully merged and updated from SIO code
425        windstress sign change affects
426        - exf_inscal_[u/v]stress
427        - sign of xx_tau[u/v] adjustments
428        - signs in cost_scat
429      * ctrl_get_gen: avoid update of tau[u/v] for first few days
430      * natl_box_adjoint updated and compressed
431      * 2-level checkpoint switch added
432        (tested in EXP. 1 of natl_box_adjoint)
433      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
434    o SVD
435      * first complete, non-hacked version for SVD calculations
436      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
437        performed via direct access files admtlm_vector.it????
438        (via ctrl_[un]pack)
439      * optimcycle is used for ARPACK iteration counter
440        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
441      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
442        and add linear transforms where necessary
443      * controls are initial/final SST, SSS (can be extended; need to check
444        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
445    o mdsio: filename info to both stderr, stdout
446    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
447      from sign change
448    
449    checkpoint55j_post
450    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
451      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
452    o add consistent build directories and .cvsignore files to verification
453    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
454    o make all subroutines 30 or less characters in length for certain older
455      compilers to work (a thorough search only turns up two routines in
456      pkg/ptracers)
457    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
458      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
459    
460    checkpoint55i_post
461    o change arrays for total vertical diffusivity (2.D if explicit,
462      3.D if implicit) ; each ptracer uses its own background value.
463    o added mnc/NetCDF output capability to ocn_compon_interf
464      - added bits to verification/cpl_aim+ocn so that it can run on
465        ITRDA and other clusters without the mpirun "-wd" option
466    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
467      configuration
468    o give MNC the ability to create additional files rather than
469      exceeding a specified file size limit "MNC_MAX_FILESIZE"
470      - the default is just less than 2GB which is a practical limit
471        on many systems
472    o Compute the non-local term using either KPP vertical diffusivity (=default)
473       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
474    
475    checkpoint55h_post
476    o add verification test "vermix"
477    o remove all the *_ioinc flags and replace with the single global
478      outputTypesInclusive flag
479    o allow to set a vertical profile of vertical diffusivity for T & S
480    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
481    o useMNC moved from data.mnc to data.pkg
482    
483    checkpoint55g_post
484    o Renaming carbon AD experiments to comply with testreport conventions
485    o Updating adjoint of Held-Suarez hs94.1x64x5
486    o Fixing directives for non-ECCO forward_step, after ECCO directives
487      have been fixed to avoid recomp. of do_oceanic_phys
488      Works well for global_ocean.90x40x15,
489      but recomp. issue remains for carbon
490    o Updating adjoint output for natl_box_adjoint after
491      pkg/ecco has been modified (see taga c55d_post)
492    
493    checkpoint55f_post
494    o rename to timeave_init_fixed
495    
496    checkpoint55e_post
497    o some delicate re-shuffle of store directives to avoid one
498      extra call of do_oceanic_physics
499      affects ecco_the_main_loop.F, do_oceanic_physics.F
500      checkpoint_lev1_directives.h
501    o NB: this may break global_ocean adjoint temporarily,
502      but it is clear how to fix it. Will do later, need this now.
503    
504    checkpoint55d_post
505    o ECCO specific cost function terms (up-to-date with 1x1 runs)
506    o ecco_cost_weights is modified to 1x1 runs
507    o modifs to allow observations to be read in as
508      single file or yearly files
509    o enable to read exf forcing fields as either
510      single file or yearly files (flag useExfYearlyFields)
511    checkpoint55d_pre
512    
513    o switch between 2-level and 3-level checkpointing
514    o add ability of MNC to write local and "partial" (eg. 2D slices where
515      the full 3D field is never actually stored) arrays to NetCDF files
516      with the correct (that is, the complete multi-dimensional) set of
517      array indicies
518      - used in mom_vecinv() to write the diagFreq output
519      - tested (demonstrated) in verification/aim.5l_cs
520    o further mnc-ification
521      - add verification/lab_sea to the list with mnc setups
522      - fix undefined mnc v-names in cd_code
523      - add kpp to mnc output (both snapshot and timeave)
524    o non-hydrostatic code
525      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
526        in calc_gw.F
527      - defaults to viscAh
528      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
529        friction or Leith) in non-hydrostatic mode, as long as there is
530        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
531    o pkg/cost
532      extend simple cost functions to treat time mean quantities
533      (T,U,V) via cost_accumulate_state from cost_tile
534    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
535        be 2 times larger than the minimum size the advection scheme requires.
536        now get a perfect conservation of salt in advect_cs test-exp (updated)
537    o GGL90 (Gaspar's TKE mixed layer)
538      - add horizontal diffusion of TKE, requires exchanges in
539        do_fields_blocking_exchanges, horizontal diffusivity is zero by
540        default. In OPA there is no horizontal diffusion of TKE but the
541        mixing coefficients are computed from a horizontal average of TKE of
542        6 points or so. I think that diffusion has a little more physical
543        justification.
544      - clean up ggl90_calc in the hope of reducing memory usage (this hope
545        was in vain)
546      - mask tke-variable in ggl90_init
547    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
548    o fix biharmonic diffusion on CS-grid.
549    o more obcs stuff
550      - added obcs_external_fields_load as an alternative to the EXF-pkg option
551        for reading boundary values. This routine is called from
552        obcs_prescribe_read
553      - updated obcs_check
554      - changed sponge layer relaxation parameter units for days to seconds
555      - turned off sponge layer by default
556      - changed argument list of OBCS_CALC to myTime+deltaTclock
557      - fixed about 35 bugs in obcs_external_fields_load
558    
559    checkpoint55c_post
560    o obcs stuff
561      - new runtime flags useOBCSprescribe, useOBCSbalance
562      - re-arranged obcs_calc
563      - moved exf_getobcs to obcs_prescibe_read
564        obcs_prescibe_read is called after ORLANSKI stuff
565        and independent of it (executable can contain all).
566      - updated obcs_check
567      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
568        These may be necessary only if tangential velocities are
569        prescribed at OB, not sure, needs testing.
570    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
571      which simplifies the calls and passes the ifc check-bounds test
572    
573    checkpoint55b_post
574    o add a 2D scalar, Z location, exchange_2 routine.
575    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
576      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
577      affects advect_cs results (for the wrong reason): update output.txt
578    o use a more standard discretization for biharmonic viscosity ;
579     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
580      affects results of dome set-up: update output.txt
581    o fix gad_advection.F (CubedSphere part), back to version 1.23
582    o fix bug in mom_vi_del2uv.F (CubedSphere part).
583    
584    checkpoint55a_post
585    o merged code to
586      * prescribe/read time-dependent open boundaries
587        (works in conjunction with exf, cal)
588      * sponge layer code for open boundaries
589      * each boundary N/S/E/W now has its own CPP option
590        (healthy for the adjoint)
591    
592    checkpoint55
593    o up-to-date adjoint of previous breaks
594      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
595      - global_ocean_ebm: adjoint still needs fix (TLM ok)
596      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
597      - carbon: * remove tr1-related adjoint verification
598                * add ptracer as control variable
599    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
600      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
601    
602    checkpoint54f_post
603    o in verification/carbin/ remove experiment related to
604      ALLOW_PASSIVE_TRACER (array tr1 etc)
605      code_ad/ input_ad/ results_ad
606    
607    o add two new packages
608      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
609        + subject to optimization (memory)
610      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
611        + subject to reordering (many GOTOs in the original code)
612        + so far opps is called for every (i,j) point, and then operates in
613          the vertical; one may want to reorder the scheme in order operate in
614          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
615          fields)
616    o overhaul of IO so that we now have flags for MDSIO and/or MNC
617      - all verification tests compile and run with linux_ia32_g77
618      - defaults are compatible with current input files--nothing
619        should change if you were not previously using MNC
620      - MNC output has been added in numerous places (eg. timeave)
621        but there are still a few writes not yet do-able with MNC
622        (this is in progress)
623      - flags now allow for either/or/both use of MDSIO and MNC and
624        documentation will soon follow
625      - numerous small formatting cleanups for ProTeX
626    o add version info (via BUILD_INFO.h) to MNC and stdout
627    
628    checkpoint54e_post
629    o add two new packages
630      - pp81 (Packanowski and Philander, 1981), Richardson number and
631        stratification dependent mixing
632      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
633      - these scheme operate in a similar manner as KPP (without ghat, of
634        course), however there is only one diffusivity that is used for both
635        temperature and salinity (and passive tracers)ç
636    o add offline package
637    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
638      provided by Stephanie Dutkiewicz
639    o genmake2: add ability to search for C compilers and cleanup test output
640      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
641    
642    checkpoint54d_post
643    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
644    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
645      leading to additional shift by 5 days each year of integration
646       (i.e. leading to considerable offset over the years)
647    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
648    o start with no AB and no initial filtering (staggerTimeStep):
649      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
650    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
651      (external loading & cpl import/export stay in forward_step.F)
652    o update coupling interface to work with new staggerTimeStep
653    o change MDSIO ptracers_pickup.
654    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
655    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
656    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
657    
658    checkpoint54c_post
659    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
660      this affects (truncation error) output.txt of test-exp:
661       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
662    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
663    o change Qnet to always be the net heat flux, (+upward).
664      affects (truncation error) output of natl_box exp.: updated
665    o define the max number of passive tracers in PTRACERS_SIZE.h
666    o start to test mnc routinely in exp0
667    o add sea-ice loading (sIceLoad) as a new forcing field.
668    
669    checkpoint54b_post
670    o add testreport "-j JOBS" option for parallel builds (tested and pretty
671       impressive on Altix and Opteron systems)
672    o diagnostics can now write NetCDF files through the mnc package
673    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
674    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
675    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
676      affects (truncation error) output of lab_sea & natl_box exp.: updated
677    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
678    
679    checkpoint54a_post
680    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
681    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
682    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
683    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
684      + internal_wave (shift in writing cg2d_ini_res)
685    checkpoint54a_pre
686    
687    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
688      - modified verification/lab_sea and natl_box_adjoint accordingly
689    
690  checkpoint54  checkpoint54
691  checkpoint53g_post  checkpoint53g_post
692  o prepare splitting of thermodynamics: store convect.counter in common block  o prepare splitting of thermodynamics: store convect.counter in common block
