5      ==============================      ==============================
6    
7    checkpoint57g_pre
8    
9    o make lambda[Theta,Salt]ClimRelax spatially varying
10      (default remains spatially uniform constant based on tau)
11    o added new control variables
12      * init. uVel, vVel, etanN
13      * lambda[Theta,Salt]ClimRelax
14    o separate masks used for ctrl_pack/unpack 'from write_grid' output
15      (suggested by G. Forget)
16    
17    checkpoint57f_post
18    o add parameter "baseTime" = model base time = time at iteration zero
19      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
20      account for baseTime shift
21    o move Coriolis arrays from PARAMS.h to GRID.h
22    checkpoint57f_pre
23    
24    o mnc-ifying the seaice package
25    o introduced an alternative length scale calculation for use in the limiting
26      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
27    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
28    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
29      as well as grad(vort3).  Made it compatible with both approximate form
30      for the cubed sphere and full form of these gradients.  Added flag
31      useFullLeith to select between approximate and full form.  
32    o add "d0" in getcon.F to reduce differences between compilers/platforms
33      update output.txt of exp. fizhi-gridalt-hs
34    o change port_rand funtion to allow to set the seed.
35    o fix obscure MNC bug involving conversion between reals and integers
36      - it caused no problems with certain (eg. gcc, ifc) compilers but the
37        new version is now more standards-compliant
38    o adjoint-related modifications
39      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
40      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
41      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
42    
43    checkpoint57e_post
44    o Adding eddy stress controls a la Ferreira et al.
45    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
46    
47    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
48      update output.txt of exp. fizhi-gridalt-hs
49    o add more "Z" dimensions and associated coordinate vars to MNC
50    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
51    o parameter calendarDumps: when set, approximate months (30-31 days) and years
52      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
53      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
54      months and years.  Requires pkg/cal.
55    o diagnostics: add pickup functionality
56      - off by default for backwards compatibility
57      - current version only uses MDSIO -- MNC will be added
58    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
59    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
60    
61    checkpoint57d_post
62    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
63    o modify verification/ideal_2D_oce so that it tests the creation of mnc
64      output from the diagnostics package
65    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
66    o make genmake2 more portable by using ".$FS" instead of ".f" for more
67      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
68    o add coordinate variables to the MNC output from the diagnostics package
69    o change MNC-flags default value: true when useMNC=TRUE
70    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
71      the ability (off by default) to read the grid information using MNC
72    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
73    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
74    o do snap-shot diagnostics at the middle of the time-interval (instead of
75      at the end).
76    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
77      new test for AIM with thSIce + slab-ocean
78    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
79    o move state variable diagnostics to the beginning of the time step ;
80      (note: still needs some work specially for snap-shot diagnostics)
81      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
82    
83    checkpoint57c_post
84    o Change testing option (-ieee) to get closer agreement between g77 & ifort
85    o generate new output.txt files on faulks with g77 & the new -ieee option
86    checkpoint57c_pre
87    
88    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
89      update output.txt of exp. global_ocean.90x40x15
90    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
91      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
92    o add saltFlux(+File) forcing capability with periodicExternalForcing
93    o allow to use pkg diagnostics for GM-Redi & ThSIce output
94    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
95    o improvements for the MNC output from DIAGNOSTICS:
96      - correct handling of the unlimitied dimension
97      - all dims now have associated coordinate variables
98      - variables located at U, V, and Corner ("Z") points are now written
99        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
100        *all* data points are output
101    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
102    o added pkg/seaice/seaice_monitor.F
103    o mdsio_readfield.F can now read files visible only to master MPI process.
104    o pkg/seaice: some test code for ice-modified ocean stress
105    o exf_getffields interpolation defaults to bilinear for all scalar forcing
106      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
107      spurious negative numbers for precipitation and humidity.  Will cause
108      some small numerical differences for integrations using pkg/exf/exf_interp.F.
109    o pkg/ctrl/
110      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
111        May be enabled via doPackDiag
112      *  introduce z-scaling of
113         + gradient (doZscalePack) and
114         + control (doZscaleUnpack)
115    o pkg/mdsio/
116      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
117      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
118    
119    checkpoint57b_post
120    o simplify options in diagnostics_fill arguments (remove weird combinations)
121    o fix MNC coordinate variables so that they now contain per-face index
122      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
123      general, EXCH2 grids are only aligned to a "local" coordinate system
124    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
125    o Implement instantaneous output within pkg diagnostics:
126      setting a negative frequency in data.diagnostics produces
127     "snap-shot" output (as opposed to time-average if freq > 0)
128    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
129      NOTE: change ptracer diagnostics name: use 2 characters to work with
130            more than 9 tracers. Add also diagnostics of advect & diffus flux.
131    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
132      becomes the coordinate variable for the 'T' dimension
133    o add CF-style coordinate variables to MNC
134      - just a first cut:  numbers are meaningless on the cubesphere and
135        missing along the T axis but otherwise it works!
136    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
137    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
138    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
139      this is based directly on what the model compute, so that the content of
140      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
141    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
142    o clean up build options files for SunOS, in particular
143      - remove -traditional from xmakedepend
144      - change -xarch=v9 to -xarch=native for f77
145      - restore use of make (not gmake)
146      - add CC=gcc if using g77
147    o changes per discussion of AM, JMC, & EH3 today:
148      - move redundant "grid" variables out of "state" -- in preparation of
149        creating proper CF-style coordinate variables and in recognition
150        that any/all grid variables can be easily copied (eg. w/NCO) from
151        the grid files into any of the other NetCDF files
152      - *always* output grid variables with MDSIO (this will eventually be
153        changed)
154      - output MNC grid file if useMNC is true
155    o every instance of _END_MASTER() has been found and replaced with
156      _END_MASTER( myThid ) in order to satisfy certain picky Sun
157      preprocessors
158    o re-arrange diagnostics pkg initialisation:
159     - allow each package to extend the available diagnostics list
160     - add some checking and fix small problems (multi-threaded, ...)
161     - new S/R diagnostics_fill (replace fill_diagnostics):
162       look through the short list of active diag. (instead of the long list)
163       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
164    
165    checkpoint57a_post
166    o this set of changes restores TAMC compatibility
167      tested for global_ocean.90x40x15 adjoint on trough
168      (what a pain)
169    
170    checkpoint57a_pre
171    o some modifs in tools/build_options for sunos
172    o call ctrl_pack for ctrl at end for optimcycle=0
173    
174    checkpoint57
175    o add horizontal bi-harmonic viscosity for vertical velocity
176      - new parameter viscA4W (defaults to viscA4)
177      - affects only non-hydrostatic code
178      - to be done: no-slip lateral boundary conditions
179    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
180    o implement Implicit Vertical advection for pTracers
181    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
182      (implemented also for implicit vertical diffusion & advection)
183    o OBCS: extend application of tracer open boundary conditions
184      to a strip beyond the boundary of width Olx/Oly
185    o add call monitor to TAF set of required calls (flow directives)
186      and include in natl_box_adjoint
187    o untangle a few ifdefs related to cost, ctrl, autodiff
188      untangel a few ALLOW_ECCO_OPTIMIZATION
189    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
190      (theta2, salt2 in ecco_cost_weights)
191    
192    checkpoint56c_post
193    o OBCS as control variables
194      - update ctrl_ad_diff.list, obcs_ad_diff.list
195      - remove balance of obcs controls from default
196      - fix index bug nobcs in ctrl_init
197      - fix dummy fields filen in ctrl_pack
198      - add dummy weights for obcs
199    o lsopt: comment out fort.94 output
200    o optim:
201      - remove unnecessary header files
202      - adjusted namelists
203      - add xerbla.F to Makefile
204    o exf:
205      - multiple modifications of exf_check_range
206      - unit change in exf_init_runoff from [m/year] to [m/s]
207    o mdsio:
208      - i/o-vector change debugLevel from debLevA to debLevB
209    
210    checkpoint56b_post
211    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
212      is called from DO_THE_MODEL_IO
213      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
214      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
215      - clean up PTRACERS_WRITE_TIMEAVE a little
216    o add another verification experiment that tests both the cfc-pkg and
217      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
218      reactive tendencies treated inline with regular timestepping
219    o testreport previously did a lousy job of comparing small numbers, so
220      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
221      implemented in the little c-progam tmp_cmpnum.c which is embedded in
222      testreport.
223    o ptracers_monitor: bug fix for MPI
224    
225    checkpoint56a_post
226    o GCHEM: finish reorganizating the package
227      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
228        (introduces another 3D-array for each passive tracer, but only if
229        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
230        gchemTendency is not needed because the timestep is done separately)
231      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
232      - GCHEM is now---more or less cleanly---separate from PTRACERS
233      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
234        so clear to me how that should be done in a general way.
235    o CFC: improve formatting of output in CFC_ATMOS
236    o PTRACERS:
237      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
238        that ALL experiments with ptracers enable can be checked. This makes
239        GCHEM_MONITOR obsolete.
240      - include a runtime parameter PTRACERS_monitorFreq that defaults to
241        monitorFreq
242      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
243    o add PTRACERS (PTR0[1-5]) to testreport output
244    o exf_check_range:
245      * default changed to .TRUE.
246      * will check values for niter0 if debLevA, every timestep if debLevB
247      * STOP in exf_check_range if 'out of range'
248      * range chosen generous to allow for potential extema
249      TBD: a version with stricter range
250           permitted range would be runtime parameters
251    o GMredi:
252      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
253      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
254      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
255    o GCHEM:
256      - move call to GCHEM_FORCING_SEP, so that it is now called before
257        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
258      - introduced a useGCHEM runtime flag and applied it everywhere.
259      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
260        this flag is now only visible within GCHEM-pkg routines.
261      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
262        be replaced by a 3D array that is computed before thermodynamics; for
263        this, the tracer ID iTracer had to be included into the parameter list
264        of ptracers_forcing
265      - set up forward_step to call gchem_forcing, that will replace
266        gchem_forcing_int in ptracers_forcing
267      - cleaning up
268    o small cleaning of exch2: remove files that are also in eesupp/src
269    
270    checkpoint56
271    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
272    o mnc: cleanup "full" files--fixes out-of-memory problem
273    o ECCO-GODAE
274      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
275      * fully merged and updated from SIO code
276        windstress sign change affects
277        - exf_inscal_[u/v]stress
278        - sign of xx_tau[u/v] adjustments
279        - signs in cost_scat
280      * ctrl_get_gen: avoid update of tau[u/v] for first few days
281      * natl_box_adjoint updated and compressed
282      * 2-level checkpoint switch added
283        (tested in EXP. 1 of natl_box_adjoint)
284      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
285    o SVD
286      * first complete, non-hacked version for SVD calculations
287      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
288        performed via direct access files admtlm_vector.it????
289        (via ctrl_[un]pack)
290      * optimcycle is used for ARPACK iteration counter
291        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
292      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
293        and add linear transforms where necessary
294      * controls are initial/final SST, SSS (can be extended; need to check
295        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
296    o mdsio: filename info to both stderr, stdout
297    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
298      from sign change
299    
300    checkpoint55j_post
301    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
302      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
303    o add consistent build directories and .cvsignore files to verification
304    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
305    o make all subroutines 30 or less characters in length for certain older
306      compilers to work (a thorough search only turns up two routines in
307      pkg/ptracers)
308    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
309      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
310    
311    checkpoint55i_post
312    o change arrays for total vertical diffusivity (2.D if explicit,
313      3.D if implicit) ; each ptracer uses its own background value.
314    o added mnc/NetCDF output capability to ocn_compon_interf
315      - added bits to verification/cpl_aim+ocn so that it can run on
316        ITRDA and other clusters without the mpirun "-wd" option
317    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
318      configuration
319    o give MNC the ability to create additional files rather than
320      exceeding a specified file size limit "MNC_MAX_FILESIZE"
321      - the default is just less than 2GB which is a practical limit
322        on many systems
323    o Compute the non-local term using either KPP vertical diffusivity (=default)
324       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
325    
326    checkpoint55h_post
327    o add verification test "vermix"
328    o remove all the *_ioinc flags and replace with the single global
329      outputTypesInclusive flag
330    o allow to set a vertical profile of vertical diffusivity for T & S
331    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
332    o useMNC moved from data.mnc to data.pkg
333    
334    checkpoint55g_post
335    o Renaming carbon AD experiments to comply with testreport conventions
336    o Updating adjoint of Held-Suarez hs94.1x64x5
337    o Fixing directives for non-ECCO forward_step, after ECCO directives
338      have been fixed to avoid recomp. of do_oceanic_phys
339      Works well for global_ocean.90x40x15,
340      but recomp. issue remains for carbon
341    o Updating adjoint output for natl_box_adjoint after
342      pkg/ecco has been modified (see taga c55d_post)
343    
344    checkpoint55f_post
345    o rename to timeave_init_fixed
346    
347    checkpoint55e_post
348    o some delicate re-shuffle of store directives to avoid one
349      extra call of do_oceanic_physics
350      affects ecco_the_main_loop.F, do_oceanic_physics.F
351      checkpoint_lev1_directives.h
352    o NB: this may break global_ocean adjoint temporarily,
353      but it is clear how to fix it. Will do later, need this now.
354    
355    checkpoint55d_post
356    o ECCO specific cost function terms (up-to-date with 1x1 runs)
357    o ecco_cost_weights is modified to 1x1 runs
358    o modifs to allow observations to be read in as
359      single file or yearly files
360    o enable to read exf forcing fields as either
361      single file or yearly files (flag useExfYearlyFields)
362    checkpoint55d_pre
363    
364    o switch between 2-level and 3-level checkpointing
365    o add ability of MNC to write local and "partial" (eg. 2D slices where
366      the full 3D field is never actually stored) arrays to NetCDF files
367      with the correct (that is, the complete multi-dimensional) set of
368      array indicies
369      - used in mom_vecinv() to write the diagFreq output
370      - tested (demonstrated) in verification/aim.5l_cs
371    o further mnc-ification
372      - add verification/lab_sea to the list with mnc setups
373      - fix undefined mnc v-names in cd_code
374      - add kpp to mnc output (both snapshot and timeave)
375    o non-hydrostatic code
376      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
377        in calc_gw.F
378      - defaults to viscAh
379      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
380        friction or Leith) in non-hydrostatic mode, as long as there is
381        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
382    o pkg/cost
383      extend simple cost functions to treat time mean quantities
384      (T,U,V) via cost_accumulate_state from cost_tile
385    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
386        be 2 times larger than the minimum size the advection scheme requires.
387        now get a perfect conservation of salt in advect_cs test-exp (updated)
388    o GGL90 (Gaspar's TKE mixed layer)
389      - add horizontal diffusion of TKE, requires exchanges in
390        do_fields_blocking_exchanges, horizontal diffusivity is zero by
391        default. In OPA there is no horizontal diffusion of TKE but the
392        mixing coefficients are computed from a horizontal average of TKE of
393        6 points or so. I think that diffusion has a little more physical
394        justification.
395      - clean up ggl90_calc in the hope of reducing memory usage (this hope
396        was in vain)
397      - mask tke-variable in ggl90_init
398    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
399    o fix biharmonic diffusion on CS-grid.
400    o more obcs stuff
401      - added obcs_external_fields_load as an alternative to the EXF-pkg option
402        for reading boundary values. This routine is called from
403        obcs_prescribe_read
404      - updated obcs_check
405      - changed sponge layer relaxation parameter units for days to seconds
406      - turned off sponge layer by default
407      - changed argument list of OBCS_CALC to myTime+deltaTclock
408      - fixed about 35 bugs in obcs_external_fields_load
409    
410    checkpoint55c_post
411    o obcs stuff
412      - new runtime flags useOBCSprescribe, useOBCSbalance
413      - re-arranged obcs_calc
414      - moved exf_getobcs to obcs_prescibe_read
415        obcs_prescibe_read is called after ORLANSKI stuff
416        and independent of it (executable can contain all).
417      - updated obcs_check
418      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
419        These may be necessary only if tangential velocities are
420        prescribed at OB, not sure, needs testing.
421    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
422      which simplifies the calls and passes the ifc check-bounds test
423    
424    checkpoint55b_post
425    o add a 2D scalar, Z location, exchange_2 routine.
426    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
427      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
428      affects advect_cs results (for the wrong reason): update output.txt
429    o use a more standard discretization for biharmonic viscosity ;
430     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
431      affects results of dome set-up: update output.txt
432    o fix gad_advection.F (CubedSphere part), back to version 1.23
433    o fix bug in mom_vi_del2uv.F (CubedSphere part).
434    
435    checkpoint55a_post
436    o merged code to
437      * prescribe/read time-dependent open boundaries
438        (works in conjunction with exf, cal)
439      * sponge layer code for open boundaries
440      * each boundary N/S/E/W now has its own CPP option
441        (healthy for the adjoint)
442    
443    checkpoint55
444    o up-to-date adjoint of previous breaks
445      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
446      - global_ocean_ebm: adjoint still needs fix (TLM ok)
447      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
448      - carbon: * remove tr1-related adjoint verification
449                * add ptracer as control variable
450    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
451      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
452    
453    checkpoint54f_post
454    o in verification/carbin/ remove experiment related to
455      ALLOW_PASSIVE_TRACER (array tr1 etc)
456      code_ad/ input_ad/ results_ad
457    
458    o add two new packages
459      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
460        + subject to optimization (memory)
461      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
462        + subject to reordering (many GOTOs in the original code)
463        + so far opps is called for every (i,j) point, and then operates in
464          the vertical; one may want to reorder the scheme in order operate in
465          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
466          fields)
467    o overhaul of IO so that we now have flags for MDSIO and/or MNC
468      - all verification tests compile and run with linux_ia32_g77
469      - defaults are compatible with current input files--nothing
470        should change if you were not previously using MNC
471      - MNC output has been added in numerous places (eg. timeave)
472        but there are still a few writes not yet do-able with MNC
473        (this is in progress)
474      - flags now allow for either/or/both use of MDSIO and MNC and
475        documentation will soon follow
476      - numerous small formatting cleanups for ProTeX
477    o add version info (via BUILD_INFO.h) to MNC and stdout
478    
479    checkpoint54e_post
480    o add two new packages
481      - pp81 (Packanowski and Philander, 1981), Richardson number and
482        stratification dependent mixing
483      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
484      - these scheme operate in a similar manner as KPP (without ghat, of
485        course), however there is only one diffusivity that is used for both
486        temperature and salinity (and passive tracers)ç
487    o add offline package
488    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
489      provided by Stephanie Dutkiewicz
490    o genmake2: add ability to search for C compilers and cleanup test output
491      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
492    
493    checkpoint54d_post
494    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
495    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
496      leading to additional shift by 5 days each year of integration
497       (i.e. leading to considerable offset over the years)
498    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
499    o start with no AB and no initial filtering (staggerTimeStep):
500      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
501    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
502      (external loading & cpl import/export stay in forward_step.F)
503    o update coupling interface to work with new staggerTimeStep
504    o change MDSIO ptracers_pickup.
505    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
506    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
507    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
508    
509    checkpoint54c_post
510    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
511      this affects (truncation error) output.txt of test-exp:
512       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
513    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
514    o change Qnet to always be the net heat flux, (+upward).
515      affects (truncation error) output of natl_box exp.: updated
516    o define the max number of passive tracers in PTRACERS_SIZE.h
517    o start to test mnc routinely in exp0
518    o add sea-ice loading (sIceLoad) as a new forcing field.
519    
520    checkpoint54b_post
521    o add testreport "-j JOBS" option for parallel builds (tested and pretty
522       impressive on Altix and Opteron systems)
523    o diagnostics can now write NetCDF files through the mnc package
524    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
525    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
526    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
527      affects (truncation error) output of lab_sea & natl_box exp.: updated
528    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
529    
530    checkpoint54a_post
531    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
532    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
533    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
534    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
535      + internal_wave (shift in writing cg2d_ini_res)
536    checkpoint54a_pre
537    
538    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
539      - modified verification/lab_sea and natl_box_adjoint accordingly
540    
541    checkpoint54
542    checkpoint53g_post
543    o prepare splitting of thermodynamics: store convect.counter in common block
544    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
545      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
546    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
547    o new parameter "nShapS": allow to treat differently S from T (nShapT)
548    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
549    o restore adjointability
550    
551    checkpoint53f_post
552    o modifications that affect AIM experiment results (update output.txt):
553      - no advection of S at top interface Nr (pkg/generic_advdiff)
554      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
555    o AIM pkg:
556      - include stability function into surf.Flux derivative relative to Tsurf
557      - calculate clear-sky radiation & surface temp. change (for diagnostics)
558    
559    checkpoint53e_post
560    o merged cylindrical coord configuration
561    o added rotating_tank experiment
562    checkpoint53e_pre
563    
564    checkpoint53d_post
565    o faulks upgraded: re-generate output.txt that have changed:
566       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
567    o Added Bryan and Lewis, 1979, vertical diffusivity profile
568    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
569    o added Sadourny discretization of Coriolis
570      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
571      - re-enabled use of omega3 (useAbsVorticity)
572    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
573      vector-invariant equations
574      - note: does *NOT* yet use same variable visc. for no-slip BC's.
575    o recoded the lateral boundary conditions for non-hydrostatic w, this time
576      hopefully without new bugs
577      - still to do: biharmonic friction for non-hydrostatic w
578    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
579    o regenerated output for global_ocean_ebm (using -ieee)
580    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
581      of mom_common/
582      - simple re-arrangement of instructions within computing loop
583    checkpoint53d_pre
584    
585    checkpoint53c_post
586    o new version of coupler for AIM+thSIce and Ocean models
587     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
588     - land: change Evaporation of snow
589     - aim with thSIce: fix bug in snow-precip.
590    o changes to calc_gw.F
591     - bug fix for w^2 term near the bottom boundary
592     - (hopefully) improve the lateral slip boundary condtions for use with
593        partial/looped cells
594      - because the bug fix changes two verification experiments anyway (exp5
595        and plume on slope), change the lateral boundary condition from half slip
596        to the value of no_slip_sides
597    o ebm package wasnt quite up to the parallel task. Fixed that.
598    o Adjoint of EBM package + verification
599      * TLM OK
600      * ADM not sufficient accuracy yet (needs further testing)
601    
602    checkpoint53b_post
603    o Commiting new energy balance model to repository
604      * package is pkg/ebm
605      * verif. is verification/global_ocean_ebm
606      * references are in ebm_driver.F
607    C      * X. Wang, P. Stone and J. Marotzke, 1999:
608    C        Global thermohaline circulation. Part I:
609    C        Sensitivity to atmospheric moisture transport.
610    C        J. Climate 12(1), 71-82
611    C      * X. Wang, P. Stone and J. Marotzke, 1999:
612    C        Global thermohaline circulation. Part II:
613    C        Sensitivity with interactive transport.
614    C        J. Climate 12(1), 83-91
615    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
616    C        Destabilization of the thermohaline circulation
617    C        by atmospheric eddy transports.
618    C        J. Climate 7(12), 1870-1882
619    o Will need long integration testing.
620    checkpoint53b_pre
621    
622    o created pkg/mom_common in preparation for variable viscosity code
623    o renamed and split ini_mnc_io
624    o pkg/land: only liquid water can diffuse or run-off
625    o AIM using land: soil wetness availability account for snow
626    o added printMapIncludesZeros to EEPARMS namelist
627    
628    checkpoint53a_post
629    o restore TAMC compatiility for exf_constants.h
630      (no usage of _d in .h)
631    o Additional storing in KPP in an attempt to fix
632      TAMC problem with adjoint of KPP code.
633      (no success...)
634      Identical code works fine with TAF.
635    o Fixed verification/natl_box_adjoint experiments.
636      Initial conditions for Experiments 4 and 5 are now
637      set to "SEAICE_initialHEFF=0", which is more reasonable,
638      and hence gives results closer to that of Experiment 2.
639      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
640    
641    checkpoint53
642    o stable checkpoint with up to date adjoint
643      TLM tests only run for 1st grdchk at the moment. Its unclear if
644      this is a code problem or a problem with resetting code for g_
645      variables that is being autogenerated wrong.
646      Otherwise:
647       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
648       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
649         are both still in chaos following their security messes.
650    
651    checkpoint52n_post
652    o various build (mostly genmake2) changes including:
653      - ability to build/run more easily within Cygwin and MacOS X
654      - more complicated Makefiles with a stronger dependence on Gnu Make
655    o pkg/seaice modifications
656      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
657        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
658        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
659      - changed proxy for geostrophic velocity and updated
660        verification/lab_sea/results/* accordingly
661      - removed ADI dynamic solver from pkg/seaice
662      - replaced all occurrences of 1/CSTICE or 1/CSUICE
663        they caused a segmentation fault under certain circumstances
664      - removed unused field WATR
665    o bug fix in exf-package:
666      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
667         now reflect that.
668    o small fixes in the cal-package:
669      - set reference date to first of January for the 'model'-calendar
670      - failing of cal_CheckDate in cal_FullDate now actually results in a
671        warning
672    o small modifications in exf-package to increase flexibility:
673      - change climtempfreeze from a constant to a runtime parameter that
674        is specified in data.exf_clim (default = -1.9)
675      - introduce runtime parameter windstressmax (default = 2.0) that is
676        specified in data.exf
677    o fix in pkg/thsice:
678      - update Evap (Tsf changes) to be consistent with Latent heat flux
679      - maintain snow precipitation unchanged (even if Tsf >=0).
680     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
681    
682    checkpoint52m_post
683    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
684      this does not change any of the results, because myIter=0 in swfrac always
685      lead to jwtype=2 (the default anyway), but the call makes little sense
686      as a default
687    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
688    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
689      atmospheric model (AIM) to use it ; add a "slab ocean" component.
690    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
691    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
692    o extending useSingleCpuIO option to work with new exch2 I/O format
693      - old-style, missing-tile I/O is still accessible by defining CPP
694        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
695    o monitor package can write to NetCDF files and/or STDOUT
696    o fix re-definition bug in MNC_GRID_INIT_ALL()
697    o doc/api_reference added
698      - a framework for building an API Reference Manual using all
699        the "protex" comments embedded in the code
700      - see pkg/generic_advdiff, pkg/mnc for examples
701    o MNC:
702      - make myThid the last argument for all subroutines
703      - new default for the grid files: NO halos
704      - add useMNC and other run-time flags
705      - separate per-file-group handling of the unlimited dimension
706      - early initialization of MNC w/ flags read at the eeboot stage
707        and lookup tables set in initialize_fixed
708      - write all MNC output to a freshly-created directory
709    o thermodynamics sea-ice (thsice) is now tested with testreport.
710    o test exp. advect_cs: use the standard cs32 grid ; update output.
711    o Added functionality to grdchk:
712      pick global i,j,k position (or nearest wet) where to perform check.
713    
714    checkpoint52l_post
715    o new land formulation:
716      a) use ground enthalpy as prognostic variable to ensure exact
717         energy conservation.
718      b) account for water temperature and for latent heat of freezing
719         in all processes (rain, run-off, ground storage)
720      c) compute surface and ground temperature implicitly.
721    o aim_v23 modification for new land model:
722      a) Treat separately land / ocean / sea-ice surface fluxes
723         to allow implicit computation of land & sea-ice surface temp.
724      b) add snow precipitation.
725    checkpoint52l_pre
726    
727    o fix problem (when 1 tile is empty) in min/max monitor.
728    o fix bug in timeAve (u,vZetatave in common block)
729    o no restoring terms under ice for pkg/seaice
730    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
731    o bug fix for pkg/seaice pickups
732    o change MNC call locations and add coordinate attributes
733    o mask vorticity at the corner ; affects global_ocean.cs output
734    o fix ini_curvilinear_grid ; test CS experiments with mpi
735    o aim.5l_cs: modify sea-ice fraction input file ; update output
736    o exf: Adding simple range check routine for exf fields after read
737    
738    checkpoint52k_post
739    o removed top-level directory "diags"
740      - we migrated these functions to pkg/timeave a long time ago
741    o fixed bug introduced in pkg/monitor
742    o accuracy ctrlprec = 32 insuffient for gradient checks using
743      averaged fields (I/O via cost_averages)
744      -> use ctrl.h in active_file*.F to control I/O precision.
745    o paramter list of CALL ADTHE_MAIN_LOOP
746    o added initial do_the_model_io to ecco
747    o set all ...Freq to zero after cost_final
748      taveFreq, dumpFreq, pChkptFreq
749    o MAIN and ECCO differentiability restored
750    
751    checkpoint52j_post
752    o fix nchklev in tamc.h for global_ocean...
753    o Bringing flow and store directives up-to-date
754    o Really weird thing!
755      call do_the_model_io from the_main_loop with parameters
756      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
757      TAF places a faulty re-call of initialise_varia
758      after cost_final call which should not be there!
759    checkpoint52j_pre
760    
761    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
762      error messages
763    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
764    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
765      debug output
766    o modfied mdsio_writefield.F to handle non-global files under exch2
767    o update AIM Cubed-Sphere exp (aim.5l_cs):
768      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
769    o update AIM Equatorial Channel exp:
