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

771    
772    checkpoint52k_post
773    o removed top-level directory "diags"
774      - we migrated these functions to pkg/timeave a long time ago
775    o fixed bug introduced in pkg/monitor
776    o accuracy ctrlprec = 32 insuffient for gradient checks using
777      averaged fields (I/O via cost_averages)
778      -> use ctrl.h in active_file*.F to control I/O precision.
779    o paramter list of CALL ADTHE_MAIN_LOOP
780    o added initial do_the_model_io to ecco
781    o set all ...Freq to zero after cost_final
782      taveFreq, dumpFreq, pChkptFreq
783    o MAIN and ECCO differentiability restored
784    
785    checkpoint52j_post
786    o fix nchklev in tamc.h for global_ocean...
787    o Bringing flow and store directives up-to-date
788    o Really weird thing!
789      call do_the_model_io from the_main_loop with parameters
790      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
791      TAF places a faulty re-call of initialise_varia
792      after cost_final call which should not be there!
793    checkpoint52j_pre
794    
795    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
796      error messages
797    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src

812    o updated the tiling for global_ocean_pressure
813    checkpoint52i_pre
814    
815    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of

817    
818    checkpoint52h_pre
819    o shortened offending lines in exch2_send_rx?.template
820    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator

823      old grid files, moved CPP_EEMACROS.h to pkg/exch2
824    o added useSingleCPUIO flag to monitor.F and mon_out.F
825    o added temporary hack for sea-ice dynamics on the cube:
826      metric terms are ignored and it is assumed that
827      there is no sea-ice on cube faces 1, 2, 4, and 5.
828    
829    checkpoint52f_post
830    o added exch2 cube routines to pkg/exch2

832    o added new grid files to hs94.cs-32x32x5
833    checkpoint52f_pre
834    
835    checkpoint52e_post
836    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
837      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
838    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
839      to work with implicit vertical advection and AB ;
840    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
841    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
842     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
843    checkpoint52e_pre
844    
845    o fix bug in impldiff when Nr=1 or Nr=2.
846    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
847    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
848    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
849      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
850    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
851    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
852    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
853    
854    checkpoint52d_post
855    o re-tiled many expts to allow comparison in multi-processor mode
856      - updated output accordingly
857      - changed hs94.128x64x5 to use intial T from file rather than use the
858        random number generator
859    o add infrastructure in model routines for fizhi and gridalt packages
860    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
861    o changes to permit hi-res, cubed-sphere, configuration
862      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
863      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
864      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
865        of surface winds for the cube
866      (A verification experiment, based on global_ocean.cs32x15, but with
867       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
868       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
869       complete with example surface forcing files and matlab scripts to look
870       at the output and compare it with that of global_ocean.cs32x15.)
871    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
872       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
873       to conform to the common rule.
874    o check-in the first version of the coupler + interfaces for multi-components
875       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
876       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
877       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
878       - ocean and atmos. share the same horizontal grid (no interpolation).
879       - exchanges between component and coupler is done in forward_step
880    o new verification experiment, cpl_aim+ocn:
881       coupled ocean - AIM atmosphere on cs32 grid.
882    
883    checkpoint52d_pre
884    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
885    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
886    
887    checkpoint52c_post
888    o Fixing OPTIONS files for use of exf:
889      - ALLOW_ECCO not needed
890      - ECCO_CPPOPTIONS.h should not be included from
891        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
892        as has been the case in the past
893      - All cal/exf related options are currently set in
894        single header file. Should remain so until we
895        agree on a consistent new policy.
896    o Removed all CPP options for cal package.
897      cal has no more CPP options.
898    o modified STOREs in GAD_ADVECTION
899    o corrected key comp. for passkey
900    
901    checkpoint52b_post
902    o new version: "thsice" of thermodynamic sea-ice pkg:
903     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
904     - modify fluxes but do not change theta directly;
905     - light cleaning of bulk_force pkg (still needed with thsice).
906     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
907       + output_thsice.txt to test thsice & bulk_force pkgs.
908    o put back grid & coriolis monitor output.
909    checkpoint52b_pre
910    
911    o call "do_the_model_io" at the beginning (=> dump initial state)
912    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
913    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
914      (need info on NUMBER_OF_PTRACERS)
915    o missing PTRACERS headers in some routines
916    o default tamc.h in pkg/autodiff supposed to crash
917      to ensure proper customization
918    
919    checkpoint52a_post
920    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
921      - moved surfaceTendencyTice from pkg/seaice to main code
922      - subroutine FREEZE_SURFACE now limits only surface temperature
923        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
924        => new output.txt for global_ocean.cs32x15 & global_with_exf
925      - keep the old version of FREEZE for backward compatibility;
926        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
927      - corresponding modifs for TAF directives
928    o added surface flux output variables to TIMEAVE_STATVARS

935    o some bug fixes for #undef REAL4_IS_SLOW
936    
937    checkpoint52 = ecco_c52_e35
938    o after testing adjoints of checkpoint51u_post
939    
940    checkpoint51u_post
941    o this is the post-merge tag of the ecco-branch
942      (needs another clean checkout and re-testing)
943    o various natl_box_adjoint configs and results
944      but no input fields
945    o obcs adjoint not yet merged!
946    o adding ECCO global 1x1 and 2x2 degree configs
947    o updated/extended some store directives for seaice
948    o pkg/ecco now containes ecco-specific part of cost function
949    o top level routines the_main_loop, forward_step
950      supersede those in model/src/
951      previous input data.cost now in data.ecco
952      (new namelist ecco_cost_nml)
953    o in ctrl/ cleaned some cross-dependencies and updated CPP options
954    
955    checkpoint51t_post
956    o this is the pre-merge tag of the ecco-branch
957    
958    checkpoint51s_post
959    o cleanup: removed various obsolete #define-s
960    o pkg/grdchk
961      - renamed 'ph-grd 3' to 'grad-res'
962      - merged from ecco-branch
963        (remaining bug fixes for obcs gradient checks)
964      - additional high-precision output for testreport
965        (grep for 'precision_grdchk_result')
966    
967    checkpoint51r_post
968    o cleaned up or removed CPP_OPTIONS.h files
969    o updated results for some of the tests to reflect the new
970      optfiles (-ieee: -O0 instead of -O3)
971    
972    checkpoint51q_post
973    o cd_code:
974      - moved cd_scheme.F -> cd_code_scheme.F

979      - Moving cd_code specific store dir.s to pkg/cd_code
980    o ctrl package totally restructured
981      - pack/unpack now optional and decoupled from
982        xx_/adxx_ I/O
983      - ctrl_pack/unpack cleaned
984        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
985      - confined inclusion of AD_CONFIG.h to where necessary.
986    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
987    
988    checkpoint51p_post
989    o create initial cd_code package
990      - WARNING: the initialization of fields within packages
991        is broken because INI_FIELDS (where READ_CHECKPOINT is
992        called) is called *before* PACKAGES_INIT_VARIABLES.
993        This seems to be backwards since
994        1) its important to initially zero the entire field including
995           the "halo" region
996        2) zeroing needs to be done *before* reading pickup info
997           and the pickup call might or might not happen in any
998           particular run
999      - this needs an overhaul for R2
1000    o cleanup verification/*/code/GMREDI_OPTIONS.h
1001    o cleanup testreport
1002    
1003    checkpoint51o_post

1011    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1012    o bug fix in find_alpha.F for MDJWF:
1013      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1014        change rho -> rho-rhoConst
1015      - replace call find_rho to find_rhonum

1034      - moved surfaceTendencyTice from pkg/seaice to main code
1035      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1036      - subroutine FREEZE now limits only surface temperature
1037        (this means new output.txt for global_ocean.90x40x15,
1038         global_ocean.cs32x15, and global_with_exf)
1039    o added surface flux output variables to TIMEAVE_STATVARS

1174    o extended state in checkpoint_lev?, etc.
1175    o alternative ctrl/cost with tr1 or ptracer
1176    o new comlev1_bibj_ptracers
1177    o new ptracers.flow
1178    o made ptracers_forcing same as external_forcing_s
1179    o added verification for adjoint with ptracers
1180      - adm. grdchk fail so far
1181      - tlm. grdchk OK
1182      - checked tapelev/comlev recomputations: OK
1183    <<<checkpoint51b_pre
1184    
1185    checkpoint51a_post
1186    o added code for biogeochemistry package
1187      - new pkgs: dic, gchem

1189    o modify code for biogeo packages
1190      - in model/src and pkg/ptracers
1191    
1192    checkpoint51
1193    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1194      - autodiff, ctrl, exf, grdchk, seaice
1195      kept separate packages
1196      - cost, ecco, obcs
1197    o updating verification/internal_wave, verification/lab_sea
1198      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1199    
1200    checkpoint50i_post
1201    o Preparing next differentiable checkpoint and sync
1202      of MAIN vs. ecco-branch
1203      - 1st step: this one is differentiable
1204      - 2nd step: next(! not this) checkpoint will have updated packages
1205                  from ecco-branch)
1206    
1207    checkpoint50h_post
1208    o new package "land": provide surface BC for AIM.
1209    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1210    o AIM: use true log-P extrapolation for near surface temp (= as in
1211        F.Molteni paper) ; update aim.5l_cs output.
1212    o New variable in PARM03 for more flexible pickups
1213    o somewhat cleaned package initialisation sequence for
1214      ctrl/ cost/ ecco/ in packages_... routines
1215    
1216    checkpoint50g_post
1217    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1218      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1219      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1220        made the default because of faster convergence than ADI
1221    
1222    checkpoint50f_post
1223    o exf totally restructured
1224      - replaced all exf_set_ routines by one generic exf_set_gen.F
1225        and made sure it's still differentiable
1226      - split exf_getffields.F into new exf_bulkformulae.F
1227      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1228      - updated adjoint/makefile and relevant verif. accordingly
1229    
1230    checkpoint50f_pre

1238     o removed lots of single quotes from comments
1239    
1240    checkpoint50e_post
1241    o make KPP work with PTRACERS
1242     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1243       nearly a copy of kpp_transport_s
1244     - there is no analogue to SurfaceTendencyS, so I have to use
1245       gPtr(of the surface layer) instead
1246    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1247    checkpoint50e_pre
1248    
1249    checkpoint50d_post
1250    o change kpp output from multiple-record state files to single-record state
1251      files analogous to write_state.F
1252    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1253      analogous to the cg2d-related output.
1254    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1255      so that writing to internal file fn (with length 512) fails.
1256    checkpoint50d_pre
1257    
1258    checkpoint50c_post
1259    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1260    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1261    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1262    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1263    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1264    
1265    checkpoint50c_pre
1266    Merging from release1_p13:
1267    o bug fix for pkg/seaice dynamic solver
1268    o Added SEAICE_initialHEFF to pkg/seaice
1269    
1270    checkpoint50b_post
1271    o store u*,v* in gU,V instead of in guNm1,gvNm1
1272    o in order to put the momForcing out of the Adams-Bashforth:
1273      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1274      to timestep.F
1275    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1276    o re-generate output for highly sensitive test-exp:
1277       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1278    
1279    checkpoint50b_pre
1280    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1281    o corrected CPP option mismatch in exf_Bulk... functions for case
1282      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1283    
1284    checkpoint50a_post
1285    o Bug fix for merging between c50 and KPP.
1286      ikey was passed from thermodynamics to kpp_calc via
1287      common block rather than being recomputed in kpp_calc,
1288      in contradiction with new key itdkey.
1289      New key ikppkey created, and tamc.h headers updated.
1290    
1291    checkpoint50
1292    - 2nd step of merge with ecco-branch:
1293      merge changes in ecco-branch back into main trunk
1294    - bug fix in find_alpha
1295    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1296    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1297    - merged some sliced AD support routines
1298    
1299    checkpoint49
1300    merged from ecco-branch:
1301    o exf:
1302      - Enable initialisation of forcing fields to constant
1303        (runtime) values.
1304      - in exf_getffields.F
1305        Reduce i-/j-loop to interior domain, discarding overlaps.
1306        That also fixes wrong TAF-key computations for key_1, key_2
1307        with bulf formulae.
1308      - exf_init.F modify #ifdef for exf_init_evap
1309      - exf_getffieldrec.F, ctrl_getrec.F
1310        The following INT-usages are not safe:
1311          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1312          fldcount = int(fldsecs/fldperiod) + 1
1313        and were modified.
1314    o autodiff: checkpoint_lev...
1315      - updated storing for bulk formulae (some arrays were missing)
1316      - added state for seaice package
1317      - synchronized with main branch
1318    o DIVA:
1319      Modif.s in
1320      - the_main_loop.F
1321      - the_model_main.F
1322      and added cost_final_restore.F cost_final_store.F
1323      o With these changes, it is possible to fully separate
1324        the first forward run to compute the cost function (mdthe_main_loop)
1325        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1326        into separate model executions.
1327        This enables better tuning of DIVA to given queue sizes.
1328      o Loss of cost function value in consecutive DIVA runs is
1329        fixed by storing to 'costfinal' file.
1330      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1331        beginning/end of adjoint integration is accounted for.
1332      The current changes apply to TAF-1.4.26.
1333      TAF has one remaining bug, requiring one manual change
1334      (see MITgcm manual).
1335    o cal: synchronized between MAIN and ecco-branch
1336    
1337    checkpoint48i_post
1338    o Changes to restore differentiability of code w.r.t. previous tag
1339      (mostly adding new routines to make list and replacing
1340      pressure by totPhiHyd).
1341    o Updated and merged grdchk package
1342      - has both ADM and TLM checks
1343      - works for single- and multi-proc.
1344      - output cleaned
1345      - worked successfully for parallel DIVA
1346    o genmake:
1347      - Adding -platform=SP4
1348      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1349    o Modif. for DIVA:
1350      ctrl_unpack should not be called in intermediate DIVA interval.
1351      (similar thing would apply for active files such as
1352      tbar, sbar, psbar, which should not be reinitialised;
1353      only relevant for ecco-branch)
1354    
1355    checkpoint48h_post
1356    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1357    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1358    o Added SEAICE_initialHEFF to pkg/seaice
1359    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1360    
1361    checkpoint48g_post
1362    --- EOS:
1363    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1364      store total Potential in totPhyHyd for diagnostics & EOS.
1365    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1366    --- Pressure/geopotential gradient:
1367    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1368    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1369      ( changes results of global_ocean_pressure )
1370    o NLFS + z-coord.: add eta*Rho' contribution.
1371    o accurate phiHyd when using interface-W at the middle between 2 centers
1372     ( changes results of ideal_2D_oce )
1373    o includes r* 2nd term in potential gradient.
1374    
1375    checkpoint48f_post
1376    Merging from release1_p12:
1377    o Modifications for using pkg/exf with pkg/seaice
1378      - improved description of the various forcing configurations
1379      - added basic radiation bulk formulae to pkg/exf
1380      - units/sign fix for evap computation in exf_getffields.F
1381      - updated verification/global_with_exf/results/output.txt
1382    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1383      (SBO) core products, including oceanic mass, center-of-mass,
1384      angular, and bottom pressure (see pkg/sbo/README.sbo).
1385    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1386      to avoid negative values in shallow regions.
1387      - updated verification/natl_box/results/output.txt
1388      - updated verification/lab_sea/results/output.txt
1389    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1390    o Added useSingleCpuIO option (see PARAMS.h).
1391    o Updated useSingleCpuIO option in mdsio_writefield.F to
1392      work with multi-field files, e.g., for single-file pickup.
1393    o pkg/seaice:
1394      - bug fix in growth.F: QNET for no shortwave case
1395      - added HeffFile for specifying initial sea-ice thickness
1396      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1397    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1398      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1399    o pkg/seaice:
1400      - adjoint-friendly modifications
1401      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1402    
1403    checkpoint48e_post
1404    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1405    o dynamics: change definition of computational domain & adapt mom_fluxform
1406      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1407    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1408        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1409        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1410        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1411        inverted_barometer solid-body.cs-32x32x1
1412      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1413    
1414    checkpoint48d_post
1415    o in preparation for r*:
1416     a) use pre-computed gradient of hydrostatic potential:
1417        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1418     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1419        => affects results of glob_oce_pressure (different truncation error)  
1420      update output.txt of ideal_2D_oce & global_ocean_pressure
1421    
1422    checkpoint48d_pre
1423    o in preparation for r*:
1424      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1425      pass the 2 comp. of the grad. as arguments to momentum S/R.
1426      but for the moment, only used if it does not change the results.
1427    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1428    
1429    checkpoint48c_post
1430    Modifications in treatment of initial flux forcing controls
1431    to avoid extra storing of flux fields.
1432    
1433    checkpoint48c_pre
1434    o Added tidal_basin_2d experiment (currently 1D!)
1435    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1436    
1437    checkpoint48b_post
1438    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1439     (modification to pressure gradient not yet implemented)
1440    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1441      (for U & V) that are used for vertical advection of momentum.
1442    
1443    checkpoint48a_post
1444    o In preparation for r*, use temp. array to compute vertical transport
1445       in flux-form momentum pkg. => change results of few test-exp.
1446      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1447                        lab_sea, natl_box & plume_on_slope
1448    
1449    checkpoint48
1450    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1451    
1452    checkpoint47j_post
1453    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1454    o moved adexch from forward_step to addummy_in_stepping
1455    o added exch in ctrl_map_...
1456    o aveFreq.=0. at end of cost_final to avoid overwrite in
1457      reverse checkpointing loop
1458    o Yet more changes in gmredi:
1459      * adgmredi_calc_tensor
1460        avoiding all recomputation of gmredi_slope_limit
1461      * adgmredi_x/y/rtransport
1462        added flag for excessive storing to avoid recomp. of
1463        u/v/rtans, dTdx/y/z
1464        -> this is not really necessary and very memory-consuming
1465      * adgmredi_slope_psi:
1466        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1467      * gmredi_slope_limit
1468        re-activated full calculation of taperfct for case 'ac02'
1469    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1470    
1471    checkpoint47i_post
1472    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1473    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1474      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1475    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1476    o gmredi: fix few bugs.
1477    
1478    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1479    This will be a good checkpoint to plug into the ecco-branch.
1480    o few modif.'s to get latest version adjointed
1481      (mainly kick out code in ini_linear_phisurf)
1482    o modif's to run adjoint with exactConserv
1483    o case GM_BOLUS_ADVEC should be cleaned
1484      S/R gmredi_slope_psi should be cleaned
1485    o verification/carbon now has exactConserv=.TRUE.
1486    
1487    checkpoint47g_post
1488    o time-average AIM output: becomes independent from statvars time-average
1489      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1490    o After TAF bug fix:
1491      Tested adjoint of gmredi package.
1492      Tests were done with checkpoint47 rather than with latest
1493      checkpoint47f_post since the latter is broken for the adjoint
1494      verification/carbon/ contains both ADM and TLM gradient checks.
1495    Here they are, before they get changed/lost/stolen.
1496    Mostly modif.'s to fix numerical sensitivities.
1497    Gradient checks OK for
1498    - GM_taper_scheme:
1499      * clipping
1500      * ac02
1501      * linear
1502      * glw91
1503      * dm95
1504      * ldd97
1505    - GMREDI_OPTIONS:
1506      * GM_VISBECK_VARIABLE_K
1507      * GM_NON_UNITY_DIAGONAL
1508      * GM_EXTRA_DIAGONAL
1509      * GM_BOLUS_ADVEC
1510    in conjunction with data.gmredi parameters to be checked in
1511    in a few minutes under verification/carbon/code/
1512    
1513    checkpoint47f_post
1514    Merging from release1_p10:
1515    o modifications for using pkg/exf with pkg/seaice
1516      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1517        and SEAICE_EXTERNAL_FLUXES
1518      - pkg/exf CPP options EXF_READ_EVAP and
1519        EXF_NO_BULK_COMPUTATIONS
1520      - usage examples are Experiments 8 and 9 in
1521        verification/lab_sea/README
1522      - verification/lab_sea default experiment now uses
1523        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1524    
1525    checkpoint47e_post
1526    o created a tag prior to creating a branch
1527    
1528    checkpoint47d_post
1529    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1530      at the bottom boundary had an erroneous half slip boundary condition
1531    o added bottom drag and no slip boundary condition capabilities to
1532      oceanic pressure coordinates code
1533    o added new verification experiment global_ocean_pressure, this experiment is
1534      also described in the tutorial section of the manual
1535    checkpoint47d_pre
1536    
1537    checkpoint47c_post
1538    o Added a verification experiment for a global cubed-sphere ocean run
1539      -  verification/global_ocean.cubed32x32x30
1540      -  uses pkg/therm_seaice and pkg/bulk_forcing
1541    
1542    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1543    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1544      when using P-coordinate; only implemented for atmospheric config.
1545    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1546      NOTES: requires option NONLIN_FRSURF to be "#define".
1547    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1548    
1549    checkpoint47b_post
1550    Merging from release1_p9:
1551    o pkg/seaice
1552      - removed GOTO's and added taf directives
1553      - double precision constants to reduce the g77 (Linux)
1554        to F77 (SGI) differences reported in release1_p8
1555    o tools/genmake
1556      - added SGI options
