5      ==============================      ==============================
6    
7    o adding precip control xx_precip
8    o moved ptracer ctrl index 17 -> 32
9    o in natl_box_adjoint:
10      * updated: results_bulk/
11      * not yet updated: results/, results_seaice/
12    o enable useSingleCpuIO for mdsio vector routines
13      (applies in particular to tapelev I/O)
14    o removed inefficient K-loop in all active_file*control*.F
15    
16    checkpoint57m_post
17    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
18      and advect_cs (use EXCH-2 and standard cs-32 grid files).
19    o pkg/exch2: filling of face-corner halo regions is optional
20      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
21    
22    checkpoint57l_post
23     tag before updating tutorials (pre-release-2)
24    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
25       for output and interpolation of input fields onto model grid)
26    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
27       Affects results of exp. rotating_tank ; update output.txt.
28    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
29          and taking the square quantity and/or using a fraction-weight field.
30    o fix aim_diagnostics_init.F mate numbers.
31    o add mnc output capability to diagnostics/diagstat and update
32      our cvsignore files for the ACSII output generated
33    
34    checkpoint57k_post
35    o lab_sea now uses diagnostics package and provides a suite of
36      new EXF diagnostics output.
37    
38    checkpoint57j_post
39    o exf
40      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
41        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
42        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
43      * extended diagnostics output
44        - now includes all EXF variables
45        - hs, hl moved to common block
46        - separate S/R for diagnostics, called after ctrl vector is added
47        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
48        - EXFqnet contains true Qnet (i.e. includes qsw)
49      * updated verif. lab_sea, global_with_exf
50      * Rearranging hflux (exf_mapfields -> exf_getforcing)
51        to ensure that diagnostics sees a true EXFqnet
52    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
53    o diagnostics pkg: change pointers so that 1 diagnostic can be used
54      several times with different frequencies.
55    o mnc-ify the thsice package as requested by Daniel Enderton
56      - the monitor--MNC output needs work
57      - many attributes need to be added (most are currently blank)
58    o mnc-ify theaim_v23 package as requested by Daniel Enderton
59      - many attributes need to be added (most are currently blank)
60    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
61    o add Sadourny like discretization to the 4th.O vorticity advection scheme
62    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
63      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
64         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
65    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
66     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
67    
68    checkpoint57i_post
69    o Diagnostics package was changed: diagnostic allocation is now deactivated
70      by setting an empty file name in the namelist (used to be by setting 0 frequency)
71    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
72      add 1rst Order upwind vertical Shear.
73    o add a quick fix for A/B checkpointing in OFFLINE mode
74    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
75      end-run around the C/Fortran linking horror in eesup/src/timers.F
76    o added pkg/runclock: allows user to terminate run based on wall clock
77    o added non-hydrostatic scaling parameter: nh_am2
78    o pkg/my82: futile attempt to make results compiler-independent by adding
79      some "_d 0", etc. no effect.
80    o for mnc output, fill the 'T' coordinate var with myTime and create a
81      separate 'iter' variable for iteration count
82    o pkg/diagnostics:
83      add new capability: output of Global/Regional & per-level statistics ;
84      tested against monitor output (including land & thSIce) on various exp.
85    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
86    
87    checkpoint57h_done
88      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
89      data.diagnostics, data.gchem, data.ptracers) is done.
90    
91    o pkg/diagnostics: prepare for Global/Regional statistics.
92      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
93    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
94      and rename it: DIFFERENT_MULTIPLE
95    
96    checkpoint57h_post
97    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
98    o pkg/diagnostics: change output frequency, now in seconds (instead
99      of Nb of iterations). This requires to change data.diagnostics.
100    checkpoint57h_pre
101    
102    o in mnc, let the user create the output dir if both mnc_outdir_date
103      and mnc_outdir_num are false
104    o add fflags() to pkg/diagnostics which allows one to specify, on a
105      per-file basis, the file precision [default behavior is unchanged]
106    o added diagnostics to pkg/kpp, including computation of mixed layer
107      depth based on a temperature/density criterion
108    o updated verification/natl_box to test the new pkg/kpp diagnostics
109    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
110    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
111    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
112      not mnc -- this mistake was found by JMC and is now corrected
113    
114    checkpoint57g_post
115    o add Adams-Bashforth 3rd Order time stepping:
116      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
117      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
118    checkpoint57g_pre
119    
120    o make lambda[Theta,Salt]ClimRelax spatially varying
121      (default remains spatially uniform constant based on tau)
122    o added new control variables
123      * init. uVel, vVel, etanN
124      * lambda[Theta,Salt]ClimRelax
125    o separate masks used for ctrl_pack/unpack 'from write_grid' output
126      (suggested by G. Forget)
127    
128    checkpoint57f_post
129    o add parameter "baseTime" = model base time = time at iteration zero
130      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
131      account for baseTime shift
132    o move Coriolis arrays from PARAMS.h to GRID.h
133    checkpoint57f_pre
134    
135    o mnc-ifying the seaice package
136    o introduced an alternative length scale calculation for use in the limiting
137      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
138    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
139    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
140      as well as grad(vort3).  Made it compatible with both approximate form
141      for the cubed sphere and full form of these gradients.  Added flag
142      useFullLeith to select between approximate and full form.  
143    o add "d0" in getcon.F to reduce differences between compilers/platforms
144      update output.txt of exp. fizhi-gridalt-hs
145    o change port_rand funtion to allow to set the seed.
146    o fix obscure MNC bug involving conversion between reals and integers
147      - it caused no problems with certain (eg. gcc, ifc) compilers but the
148        new version is now more standards-compliant
149    o adjoint-related modifications
150      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
151      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
152      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
153    
154    checkpoint57e_post
155    o Adding eddy stress controls a la Ferreira et al.
156    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
157    
158    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
159      update output.txt of exp. fizhi-gridalt-hs
160    o add more "Z" dimensions and associated coordinate vars to MNC
161    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
162    o parameter calendarDumps: when set, approximate months (30-31 days) and years
163      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
164      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
165      months and years.  Requires pkg/cal.
166    o diagnostics: add pickup functionality
167      - off by default for backwards compatibility
168      - current version only uses MDSIO -- MNC will be added
169    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
170    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
171    
172    checkpoint57d_post
173    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
174    o modify verification/ideal_2D_oce so that it tests the creation of mnc
175      output from the diagnostics package
176    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
177    o make genmake2 more portable by using ".$FS" instead of ".f" for more
178      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
179    o add coordinate variables to the MNC output from the diagnostics package
180    o change MNC-flags default value: true when useMNC=TRUE
181    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
182      the ability (off by default) to read the grid information using MNC
183    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
184    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
185    o do snap-shot diagnostics at the middle of the time-interval (instead of
186      at the end).
187    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
188      new test for AIM with thSIce + slab-ocean
189    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
190    o move state variable diagnostics to the beginning of the time step ;
191      (note: still needs some work specially for snap-shot diagnostics)
192      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
193    
194    checkpoint57c_post
195    o Change testing option (-ieee) to get closer agreement between g77 & ifort
196    o generate new output.txt files on faulks with g77 & the new -ieee option
197    checkpoint57c_pre
198    
199    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
200      update output.txt of exp. global_ocean.90x40x15
201    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
202      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
203    o add saltFlux(+File) forcing capability with periodicExternalForcing
204    o allow to use pkg diagnostics for GM-Redi & ThSIce output
205    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
206    o improvements for the MNC output from DIAGNOSTICS:
207      - correct handling of the unlimitied dimension
208      - all dims now have associated coordinate variables
209      - variables located at U, V, and Corner ("Z") points are now written
210        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
211        *all* data points are output
212    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
213    o added pkg/seaice/seaice_monitor.F
214    o mdsio_readfield.F can now read files visible only to master MPI process.
215    o pkg/seaice: some test code for ice-modified ocean stress
216    o exf_getffields interpolation defaults to bilinear for all scalar forcing
217      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
218      spurious negative numbers for precipitation and humidity.  Will cause
219      some small numerical differences for integrations using pkg/exf/exf_interp.F.
220    o pkg/ctrl/
221      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
222        May be enabled via doPackDiag
223      *  introduce z-scaling of
224         + gradient (doZscalePack) and
225         + control (doZscaleUnpack)
226    o pkg/mdsio/
227      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
228      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
229    
230    checkpoint57b_post
231    o simplify options in diagnostics_fill arguments (remove weird combinations)
232    o fix MNC coordinate variables so that they now contain per-face index
233      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
234      general, EXCH2 grids are only aligned to a "local" coordinate system
235    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
236    o Implement instantaneous output within pkg diagnostics:
237      setting a negative frequency in data.diagnostics produces
238     "snap-shot" output (as opposed to time-average if freq > 0)
239    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
240      NOTE: change ptracer diagnostics name: use 2 characters to work with
241            more than 9 tracers. Add also diagnostics of advect & diffus flux.
242    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
243      becomes the coordinate variable for the 'T' dimension
244    o add CF-style coordinate variables to MNC
245      - just a first cut:  numbers are meaningless on the cubesphere and
246        missing along the T axis but otherwise it works!
247    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
248    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
249    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
250      this is based directly on what the model compute, so that the content of
251      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
252    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
253    o clean up build options files for SunOS, in particular
254      - remove -traditional from xmakedepend
255      - change -xarch=v9 to -xarch=native for f77
256      - restore use of make (not gmake)
257      - add CC=gcc if using g77
258    o changes per discussion of AM, JMC, & EH3 today:
259      - move redundant "grid" variables out of "state" -- in preparation of
260        creating proper CF-style coordinate variables and in recognition
261        that any/all grid variables can be easily copied (eg. w/NCO) from
262        the grid files into any of the other NetCDF files
263      - *always* output grid variables with MDSIO (this will eventually be
264        changed)
265      - output MNC grid file if useMNC is true
266    o every instance of _END_MASTER() has been found and replaced with
267      _END_MASTER( myThid ) in order to satisfy certain picky Sun
268      preprocessors
269    o re-arrange diagnostics pkg initialisation:
270     - allow each package to extend the available diagnostics list
271     - add some checking and fix small problems (multi-threaded, ...)
272     - new S/R diagnostics_fill (replace fill_diagnostics):
273       look through the short list of active diag. (instead of the long list)
274       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
275    
276    checkpoint57a_post
277    o this set of changes restores TAMC compatibility
278      tested for global_ocean.90x40x15 adjoint on trough
279      (what a pain)
280    
281    checkpoint57a_pre
282    o some modifs in tools/build_options for sunos
283    o call ctrl_pack for ctrl at end for optimcycle=0
284    
285    checkpoint57
286    o add horizontal bi-harmonic viscosity for vertical velocity
287      - new parameter viscA4W (defaults to viscA4)
288      - affects only non-hydrostatic code
289      - to be done: no-slip lateral boundary conditions
290    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
291    o implement Implicit Vertical advection for pTracers
292    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
293      (implemented also for implicit vertical diffusion & advection)
294    o OBCS: extend application of tracer open boundary conditions
295      to a strip beyond the boundary of width Olx/Oly
296    o add call monitor to TAF set of required calls (flow directives)
297      and include in natl_box_adjoint
298    o untangle a few ifdefs related to cost, ctrl, autodiff
299      untangel a few ALLOW_ECCO_OPTIMIZATION
300    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
301      (theta2, salt2 in ecco_cost_weights)
302    
303    checkpoint56c_post
304    o OBCS as control variables
305      - update ctrl_ad_diff.list, obcs_ad_diff.list
306      - remove balance of obcs controls from default
307      - fix index bug nobcs in ctrl_init
308      - fix dummy fields filen in ctrl_pack
309      - add dummy weights for obcs
310    o lsopt: comment out fort.94 output
311    o optim:
312      - remove unnecessary header files
313      - adjusted namelists
314      - add xerbla.F to Makefile
315    o exf:
316      - multiple modifications of exf_check_range
317      - unit change in exf_init_runoff from [m/year] to [m/s]
318    o mdsio:
319      - i/o-vector change debugLevel from debLevA to debLevB
320    
321    checkpoint56b_post
322    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
323      is called from DO_THE_MODEL_IO
324      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
325      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
326      - clean up PTRACERS_WRITE_TIMEAVE a little
327    o add another verification experiment that tests both the cfc-pkg and
328      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
329      reactive tendencies treated inline with regular timestepping
330    o testreport previously did a lousy job of comparing small numbers, so
331      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
332      implemented in the little c-progam tmp_cmpnum.c which is embedded in
333      testreport.
334    o ptracers_monitor: bug fix for MPI
335    
336    checkpoint56a_post
337    o GCHEM: finish reorganizating the package
338      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
339        (introduces another 3D-array for each passive tracer, but only if
340        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
341        gchemTendency is not needed because the timestep is done separately)
342      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
343      - GCHEM is now---more or less cleanly---separate from PTRACERS
344      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
345        so clear to me how that should be done in a general way.
346    o CFC: improve formatting of output in CFC_ATMOS
347    o PTRACERS:
348      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
349        that ALL experiments with ptracers enable can be checked. This makes
350        GCHEM_MONITOR obsolete.
351      - include a runtime parameter PTRACERS_monitorFreq that defaults to
352        monitorFreq
353      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
354    o add PTRACERS (PTR0[1-5]) to testreport output
355    o exf_check_range:
356      * default changed to .TRUE.
357      * will check values for niter0 if debLevA, every timestep if debLevB
358      * STOP in exf_check_range if 'out of range'
359      * range chosen generous to allow for potential extema
360      TBD: a version with stricter range
361           permitted range would be runtime parameters
362    o GMredi:
363      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
364      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
365      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
366    o GCHEM:
367      - move call to GCHEM_FORCING_SEP, so that it is now called before
368        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
369      - introduced a useGCHEM runtime flag and applied it everywhere.
370      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
371        this flag is now only visible within GCHEM-pkg routines.
372      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
373        be replaced by a 3D array that is computed before thermodynamics; for
374        this, the tracer ID iTracer had to be included into the parameter list
375        of ptracers_forcing
376      - set up forward_step to call gchem_forcing, that will replace
377        gchem_forcing_int in ptracers_forcing
378      - cleaning up
379    o small cleaning of exch2: remove files that are also in eesupp/src
380    
381    checkpoint56
382    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
383    o mnc: cleanup "full" files--fixes out-of-memory problem
384    o ECCO-GODAE
385      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
386      * fully merged and updated from SIO code
387        windstress sign change affects
388        - exf_inscal_[u/v]stress
389        - sign of xx_tau[u/v] adjustments
390        - signs in cost_scat
391      * ctrl_get_gen: avoid update of tau[u/v] for first few days
392      * natl_box_adjoint updated and compressed
393      * 2-level checkpoint switch added
394        (tested in EXP. 1 of natl_box_adjoint)
395      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
396    o SVD
397      * first complete, non-hacked version for SVD calculations
398      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
399        performed via direct access files admtlm_vector.it????
400        (via ctrl_[un]pack)
401      * optimcycle is used for ARPACK iteration counter
402        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
403      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
404        and add linear transforms where necessary
405      * controls are initial/final SST, SSS (can be extended; need to check
406        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
407    o mdsio: filename info to both stderr, stdout
408    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
409      from sign change
410    
411    checkpoint55j_post
412    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
413      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
414    o add consistent build directories and .cvsignore files to verification
415    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
416    o make all subroutines 30 or less characters in length for certain older
417      compilers to work (a thorough search only turns up two routines in
418      pkg/ptracers)
419    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
420      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
421    
422    checkpoint55i_post
423    o change arrays for total vertical diffusivity (2.D if explicit,
424      3.D if implicit) ; each ptracer uses its own background value.
425    o added mnc/NetCDF output capability to ocn_compon_interf
426      - added bits to verification/cpl_aim+ocn so that it can run on
427        ITRDA and other clusters without the mpirun "-wd" option
428    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
429      configuration
430    o give MNC the ability to create additional files rather than
431      exceeding a specified file size limit "MNC_MAX_FILESIZE"
432      - the default is just less than 2GB which is a practical limit
433        on many systems
434    o Compute the non-local term using either KPP vertical diffusivity (=default)
435       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
436    
437    checkpoint55h_post
438    o add verification test "vermix"
439    o remove all the *_ioinc flags and replace with the single global
440      outputTypesInclusive flag
441    o allow to set a vertical profile of vertical diffusivity for T & S
442    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
443    o useMNC moved from data.mnc to data.pkg
444    
445    checkpoint55g_post
446    o Renaming carbon AD experiments to comply with testreport conventions
447    o Updating adjoint of Held-Suarez hs94.1x64x5
448    o Fixing directives for non-ECCO forward_step, after ECCO directives
449      have been fixed to avoid recomp. of do_oceanic_phys
450      Works well for global_ocean.90x40x15,
451      but recomp. issue remains for carbon
452    o Updating adjoint output for natl_box_adjoint after
453      pkg/ecco has been modified (see taga c55d_post)
454    
455    checkpoint55f_post
456    o rename to timeave_init_fixed
457    
458    checkpoint55e_post
459    o some delicate re-shuffle of store directives to avoid one
460      extra call of do_oceanic_physics
461      affects ecco_the_main_loop.F, do_oceanic_physics.F
462      checkpoint_lev1_directives.h
463    o NB: this may break global_ocean adjoint temporarily,
464      but it is clear how to fix it. Will do later, need this now.
465    
466    checkpoint55d_post
467    o ECCO specific cost function terms (up-to-date with 1x1 runs)
468    o ecco_cost_weights is modified to 1x1 runs
469    o modifs to allow observations to be read in as
470      single file or yearly files
471    o enable to read exf forcing fields as either
472      single file or yearly files (flag useExfYearlyFields)
473    checkpoint55d_pre
474    
475    o switch between 2-level and 3-level checkpointing
476    o add ability of MNC to write local and "partial" (eg. 2D slices where
477      the full 3D field is never actually stored) arrays to NetCDF files
478      with the correct (that is, the complete multi-dimensional) set of
479      array indicies
480      - used in mom_vecinv() to write the diagFreq output
481      - tested (demonstrated) in verification/aim.5l_cs
482    o further mnc-ification
483      - add verification/lab_sea to the list with mnc setups
484      - fix undefined mnc v-names in cd_code
485      - add kpp to mnc output (both snapshot and timeave)
486    o non-hydrostatic code
487      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
488        in calc_gw.F
489      - defaults to viscAh
490      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
491        friction or Leith) in non-hydrostatic mode, as long as there is
492        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
493    o pkg/cost
494      extend simple cost functions to treat time mean quantities
495      (T,U,V) via cost_accumulate_state from cost_tile
496    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
497        be 2 times larger than the minimum size the advection scheme requires.
498        now get a perfect conservation of salt in advect_cs test-exp (updated)
499    o GGL90 (Gaspar's TKE mixed layer)
500      - add horizontal diffusion of TKE, requires exchanges in
501        do_fields_blocking_exchanges, horizontal diffusivity is zero by
502        default. In OPA there is no horizontal diffusion of TKE but the
503        mixing coefficients are computed from a horizontal average of TKE of
504        6 points or so. I think that diffusion has a little more physical
505        justification.
506      - clean up ggl90_calc in the hope of reducing memory usage (this hope
507        was in vain)
508      - mask tke-variable in ggl90_init
509    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
510    o fix biharmonic diffusion on CS-grid.
511    o more obcs stuff
512      - added obcs_external_fields_load as an alternative to the EXF-pkg option
513        for reading boundary values. This routine is called from
514        obcs_prescribe_read
515      - updated obcs_check
516      - changed sponge layer relaxation parameter units for days to seconds
517      - turned off sponge layer by default
518      - changed argument list of OBCS_CALC to myTime+deltaTclock
519      - fixed about 35 bugs in obcs_external_fields_load
520    
521    checkpoint55c_post
522    o obcs stuff
523      - new runtime flags useOBCSprescribe, useOBCSbalance
524      - re-arranged obcs_calc
525      - moved exf_getobcs to obcs_prescibe_read
526        obcs_prescibe_read is called after ORLANSKI stuff
527        and independent of it (executable can contain all).
528      - updated obcs_check
529      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
530        These may be necessary only if tangential velocities are
531        prescribed at OB, not sure, needs testing.
532    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
533      which simplifies the calls and passes the ifc check-bounds test
534    
535    checkpoint55b_post
536    o add a 2D scalar, Z location, exchange_2 routine.
537    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
538      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
539      affects advect_cs results (for the wrong reason): update output.txt
540    o use a more standard discretization for biharmonic viscosity ;
541     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
542      affects results of dome set-up: update output.txt
543    o fix gad_advection.F (CubedSphere part), back to version 1.23
544    o fix bug in mom_vi_del2uv.F (CubedSphere part).
545    
546    checkpoint55a_post
547    o merged code to
548      * prescribe/read time-dependent open boundaries
549        (works in conjunction with exf, cal)
550      * sponge layer code for open boundaries
551      * each boundary N/S/E/W now has its own CPP option
552        (healthy for the adjoint)
553    
554    checkpoint55
555    o up-to-date adjoint of previous breaks
556      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
557      - global_ocean_ebm: adjoint still needs fix (TLM ok)
558      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
559      - carbon: * remove tr1-related adjoint verification
560                * add ptracer as control variable
561    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
562      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
563    
564    checkpoint54f_post
565    o in verification/carbin/ remove experiment related to
566      ALLOW_PASSIVE_TRACER (array tr1 etc)
567      code_ad/ input_ad/ results_ad
568    
569    o add two new packages
570      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
571        + subject to optimization (memory)
572      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
573        + subject to reordering (many GOTOs in the original code)
574        + so far opps is called for every (i,j) point, and then operates in
575          the vertical; one may want to reorder the scheme in order operate in
576          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
577          fields)
578    o overhaul of IO so that we now have flags for MDSIO and/or MNC
579      - all verification tests compile and run with linux_ia32_g77
580      - defaults are compatible with current input files--nothing
581        should change if you were not previously using MNC
582      - MNC output has been added in numerous places (eg. timeave)
583        but there are still a few writes not yet do-able with MNC
584        (this is in progress)
585      - flags now allow for either/or/both use of MDSIO and MNC and
586        documentation will soon follow
587      - numerous small formatting cleanups for ProTeX
588    o add version info (via BUILD_INFO.h) to MNC and stdout
589    
590    checkpoint54e_post
591    o add two new packages
592      - pp81 (Packanowski and Philander, 1981), Richardson number and
593        stratification dependent mixing
594      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
595      - these scheme operate in a similar manner as KPP (without ghat, of
596        course), however there is only one diffusivity that is used for both
597        temperature and salinity (and passive tracers)ç
598    o add offline package
599    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
600      provided by Stephanie Dutkiewicz
601    o genmake2: add ability to search for C compilers and cleanup test output
602      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
603    
604    checkpoint54d_post
605    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
606    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
607      leading to additional shift by 5 days each year of integration
608       (i.e. leading to considerable offset over the years)
609    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
610    o start with no AB and no initial filtering (staggerTimeStep):
611      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
612    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
613      (external loading & cpl import/export stay in forward_step.F)
614    o update coupling interface to work with new staggerTimeStep
615    o change MDSIO ptracers_pickup.
616    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
617    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
618    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
619    
620    checkpoint54c_post
621    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
622      this affects (truncation error) output.txt of test-exp:
623       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
624    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
625    o change Qnet to always be the net heat flux, (+upward).
626      affects (truncation error) output of natl_box exp.: updated
627    o define the max number of passive tracers in PTRACERS_SIZE.h
628    o start to test mnc routinely in exp0
629    o add sea-ice loading (sIceLoad) as a new forcing field.
630    
631    checkpoint54b_post
632    o add testreport "-j JOBS" option for parallel builds (tested and pretty
633       impressive on Altix and Opteron systems)
634    o diagnostics can now write NetCDF files through the mnc package
635    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
636    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
637    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
638      affects (truncation error) output of lab_sea & natl_box exp.: updated
639    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
640    
641    checkpoint54a_post
642    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
643    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
644    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
645    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
646      + internal_wave (shift in writing cg2d_ini_res)
647    checkpoint54a_pre
648    
649    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
650      - modified verification/lab_sea and natl_box_adjoint accordingly
651    
652    checkpoint54
653    checkpoint53g_post
654    o prepare splitting of thermodynamics: store convect.counter in common block
655    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
656      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
657    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
658    o new parameter "nShapS": allow to treat differently S from T (nShapT)
659    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
660    o restore adjointability
661    
662    checkpoint53f_post
663    o modifications that affect AIM experiment results (update output.txt):
664      - no advection of S at top interface Nr (pkg/generic_advdiff)
665      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
666    o AIM pkg:
667      - include stability function into surf.Flux derivative relative to Tsurf
668      - calculate clear-sky radiation & surface temp. change (for diagnostics)
669    
670    checkpoint53e_post
671    o merged cylindrical coord configuration
672    o added rotating_tank experiment
673    checkpoint53e_pre
674    
675    checkpoint53d_post
676    o faulks upgraded: re-generate output.txt that have changed:
677       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
678    o Added Bryan and Lewis, 1979, vertical diffusivity profile
679    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
680    o added Sadourny discretization of Coriolis
681      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
682      - re-enabled use of omega3 (useAbsVorticity)
683    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
684      vector-invariant equations
685      - note: does *NOT* yet use same variable visc. for no-slip BC's.
686    o recoded the lateral boundary conditions for non-hydrostatic w, this time
687      hopefully without new bugs
688      - still to do: biharmonic friction for non-hydrostatic w
689    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
690    o regenerated output for global_ocean_ebm (using -ieee)
691    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
692      of mom_common/
693      - simple re-arrangement of instructions within computing loop
694    checkpoint53d_pre
695    
696    checkpoint53c_post
697    o new version of coupler for AIM+thSIce and Ocean models
698     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
699     - land: change Evaporation of snow
700     - aim with thSIce: fix bug in snow-precip.
701    o changes to calc_gw.F
702     - bug fix for w^2 term near the bottom boundary
703     - (hopefully) improve the lateral slip boundary condtions for use with
704        partial/looped cells
705      - because the bug fix changes two verification experiments anyway (exp5
706        and plume on slope), change the lateral boundary condition from half slip
707        to the value of no_slip_sides
708    o ebm package wasnt quite up to the parallel task. Fixed that.
709    o Adjoint of EBM package + verification
710      * TLM OK
711      * ADM not sufficient accuracy yet (needs further testing)
712    
713    checkpoint53b_post
714    o Commiting new energy balance model to repository
715      * package is pkg/ebm
716      * verif. is verification/global_ocean_ebm
717      * references are in ebm_driver.F
718    C      * X. Wang, P. Stone and J. Marotzke, 1999:

730    o Will need long integration testing.
731    checkpoint53b_pre
732    
733  o created pkg/mom_common in preparation for variable viscosity code  o created pkg/mom_common in preparation for variable viscosity code
734  o renamed and split ini_mnc_io  o renamed and split ini_mnc_io
