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