113    `
114    >>>checkpoint51b_post
115    adjoint of ptracers

132    o modify code for biogeo packages
133      - in model/src and pkg/ptracers
134    
135    checkpoint51
136    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
137      - autodiff, ctrl, exf, grdchk, seaice
138      kept separate packages
139      - cost, ecco, obcs
140    o updating verification/internal_wave, verification/lab_sea
141      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
142    
143    checkpoint50i_post
144    o Preparing next differentiable checkpoint and sync
145      of MAIN vs. ecco-branch
146      - 1st step: this one is differentiable
147      - 2nd step: next(! not this) checkpoint will have updated packages
148                  from ecco-branch)
149    
150    checkpoint50h_post
151    o new package "land": provide surface BC for AIM.
152    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
153    o AIM: use true log-P extrapolation for near surface temp (= as in
154        F.Molteni paper) ; update aim.5l_cs output.
155    o New variable in PARM03 for more flexible pickups
156    o somewhat cleaned package initialisation sequence for
157      ctrl/ cost/ ecco/ in packages_... routines
158    
159    checkpoint50g_post
160    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
161      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
162      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
163        made the default because of faster convergence than ADI
164    
165    checkpoint50f_post
166    o exf totally restructured
167      - replaced all exf_set_ routines by one generic exf_set_gen.F
168        and made sure it's still differentiable
169      - split exf_getffields.F into new exf_bulkformulae.F
170      - exf_inscal_/exf_outscal_ suffixes consistent with field names

181     o removed lots of single quotes from comments
182    
183    checkpoint50e_post
184    o make KPP work with PTRACERS
185     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
186       nearly a copy of kpp_transport_s
187     - there is no analogue to SurfaceTendencyS, so I have to use
188       gPtr(of the surface layer) instead
189    o add a new platform SunFire+mpi (SunFire 15000) to genmake
190    checkpoint50e_pre
191    
192    checkpoint50d_post
193    o change kpp output from multiple-record state files to single-record state
194      files analogous to write_state.F
195    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
196      analogous to the cg2d-related output.
197    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
198      so that writing to internal file fn (with length 512) fails.
199    checkpoint50d_pre
200    
201    checkpoint50c_post
202    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
203    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
204    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
205    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
206    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
207    
208    checkpoint50c_pre
209    Merging from release1_p13:
210    o bug fix for pkg/seaice dynamic solver
211    o Added SEAICE_initialHEFF to pkg/seaice
212    
213    checkpoint50b_post
214    o store u*,v* in gU,V instead of in guNm1,gvNm1
215    o in order to put the momForcing out of the Adams-Bashforth:
216      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
217      to timestep.F
218    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
219    o re-generate output for highly sensitive test-exp:
220       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
221    
222    checkpoint50b_pre
223    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
224    o corrected CPP option mismatch in exf_Bulk... functions for case
225      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
226    
227    checkpoint50a_post
228    o Bug fix for merging between c50 and KPP.
229      ikey was passed from thermodynamics to kpp_calc via
230      common block rather than being recomputed in kpp_calc,
231      in contradiction with new key itdkey.
232      New key ikppkey created, and tamc.h headers updated.
233    
234    checkpoint50
235    - 2nd step of merge with ecco-branch:
236      merge changes in ecco-branch back into main trunk
237    - bug fix in find_alpha
238    - more storing in gmredi_calc_tensor.F, kpp_routines.F
239    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
240    - merged some sliced AD support routines
241    
242    checkpoint49
243    merged from ecco-branch:
244    o exf:
245      - Enable initialisation of forcing fields to constant
246        (runtime) values.
247      - in exf_getffields.F
248        Reduce i-/j-loop to interior domain, discarding overlaps.
249        That also fixes wrong TAF-key computations for key_1, key_2
250        with bulf formulae.
251      - exf_init.F modify #ifdef for exf_init_evap
252      - exf_getffieldrec.F, ctrl_getrec.F
253        The following INT-usages are not safe:
254          fldsecs  = int(fldsecs/fldperiod)*fldperiod
255          fldcount = int(fldsecs/fldperiod) + 1
256        and were modified.
257    o autodiff: checkpoint_lev...
258      - updated storing for bulk formulae (some arrays were missing)
259      - added state for seaice package
260      - synchronized with main branch
261    o DIVA:
262      Modif.s in
263      - the_main_loop.F
264      - the_model_main.F
265      and added cost_final_restore.F cost_final_store.F
266      o With these changes, it is possible to fully separate
267        the first forward run to compute the cost function (mdthe_main_loop)
268        and adjoint runs over individual DIVA intervals (adthe_main_loop)
269        into separate model executions.
270        This enables better tuning of DIVA to given queue sizes.
271      o Loss of cost function value in consecutive DIVA runs is
272        fixed by storing to 'costfinal' file.
273      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
274        beginning/end of adjoint integration is accounted for.
275      The current changes apply to TAF-1.4.26.
276      TAF has one remaining bug, requiring one manual change
277      (see MITgcm manual).
278    o cal: synchronized between MAIN and ecco-branch
279    
280    checkpoint48i_post
281    o Changes to restore differentiability of code w.r.t. previous tag
282      (mostly adding new routines to make list and replacing
283      pressure by totPhiHyd).
284    o Updated and merged grdchk package
285      - has both ADM and TLM checks
286      - works for single- and multi-proc.
287      - output cleaned
288      - worked successfully for parallel DIVA
289    o genmake:
290      - Adding -platform=SP4
291      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
292    o Modif. for DIVA:
293      ctrl_unpack should not be called in intermediate DIVA interval.
294      (similar thing would apply for active files such as
295      tbar, sbar, psbar, which should not be reinitialised;
296      only relevant for ecco-branch)
297    
298    checkpoint48h_post
299    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
300    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
301    o Added SEAICE_initialHEFF to pkg/seaice
302    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
303    
304    checkpoint48g_post
305    --- EOS:
306    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
307      store total Potential in totPhyHyd for diagnostics & EOS.
308    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
309    --- Pressure/geopotential gradient:
310    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
311    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
312      ( changes results of global_ocean_pressure )
313    o NLFS + z-coord.: add eta*Rho' contribution.
314    o accurate phiHyd when using interface-W at the middle between 2 centers
315     ( changes results of ideal_2D_oce )
316    o includes r* 2nd term in potential gradient.
317    
318    checkpoint48f_post
319    Merging from release1_p12:
320    o Modifications for using pkg/exf with pkg/seaice
321      - improved description of the various forcing configurations
322      - added basic radiation bulk formulae to pkg/exf
323      - units/sign fix for evap computation in exf_getffields.F
324      - updated verification/global_with_exf/results/output.txt
325    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
326      (SBO) core products, including oceanic mass, center-of-mass,
327      angular, and bottom pressure (see pkg/sbo/README.sbo).
328    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
329      to avoid negative values in shallow regions.
330      - updated verification/natl_box/results/output.txt
331      - updated verification/lab_sea/results/output.txt
332    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
333    o Added useSingleCpuIO option (see PARAMS.h).
334    o Updated useSingleCpuIO option in mdsio_writefield.F to
335      work with multi-field files, e.g., for single-file pickup.
336    o pkg/seaice:
337      - bug fix in growth.F: QNET for no shortwave case
338      - added HeffFile for specifying initial sea-ice thickness
339      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
340    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
341      kpp_transport_t.F, forward_step.F, and the_main_loop.F
342    o pkg/seaice:
343      - adjoint-friendly modifications
344      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
345    
346    checkpoint48e_post
347    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
348    o dynamics: change definition of computational domain & adapt mom_fluxform
349      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
350    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
351        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
352        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
353        global_ocean.90x40x15 global_with_exf global_ocean_pressure
354        inverted_barometer solid-body.cs-32x32x1
355      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
356    
357    checkpoint48d_post
358    o in preparation for r*:
359     a) use pre-computed gradient of hydrostatic potential:
360        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
361     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
362        => affects results of glob_oce_pressure (different truncation error)  
363      update output.txt of ideal_2D_oce & global_ocean_pressure
364    
365    checkpoint48d_pre
366    o in preparation for r*:
367      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
368      pass the 2 comp. of the grad. as arguments to momentum S/R.
369      but for the moment, only used if it does not change the results.
370    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
371    
372    checkpoint48c_post
373    Modifications in treatment of initial flux forcing controls
374    to avoid extra storing of flux fields.
375    
376    checkpoint48c_pre
377    o Added tidal_basin_2d experiment (currently 1D!)
378    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
379    
380    checkpoint48b_post
381    o r* coordinate added in #ifdef NONLIN_FRSURF block.
382     (modification to pressure gradient not yet implemented)
383    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
384      (for U & V) that are used for vertical advection of momentum.
385    
386    checkpoint48a_post
387    o In preparation for r*, use temp. array to compute vertical transport
388       in flux-form momentum pkg. => change results of few test-exp.
389      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
390                        lab_sea, natl_box & plume_on_slope
391    
392    checkpoint48
393    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
394    
395    checkpoint47j_post
396    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
397    o moved adexch from forward_step to addummy_in_stepping
398    o added exch in ctrl_map_...
399    o aveFreq.=0. at end of cost_final to avoid overwrite in
400      reverse checkpointing loop
401    o Yet more changes in gmredi:
402      * adgmredi_calc_tensor
403        avoiding all recomputation of gmredi_slope_limit
404      * adgmredi_x/y/rtransport
405        added flag for excessive storing to avoid recomp. of
406        u/v/rtans, dTdx/y/z
407        -> this is not really necessary and very memory-consuming
408      * adgmredi_slope_psi:
409        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
410      * gmredi_slope_limit
411        re-activated full calculation of taperfct for case 'ac02'
412    o updating verification/ adjoints of carbon, global_ocean.90x40x15
413    
414    checkpoint47i_post
415    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
416    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
417      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
418    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
419    o gmredi: fix few bugs.
420    
421    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
422    This will be a good checkpoint to plug into the ecco-branch.
423    o few modif.'s to get latest version adjointed
424      (mainly kick out code in ini_linear_phisurf)
425    o modif's to run adjoint with exactConserv
426    o case GM_BOLUS_ADVEC should be cleaned
427      S/R gmredi_slope_psi should be cleaned
428    o verification/carbon now has exactConserv=.TRUE.
429    
430    checkpoint47g_post
431    o time-average AIM output: becomes independent from statvars time-average
432      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
433    o After TAF bug fix:
434      Tested adjoint of gmredi package.
435      Tests were done with checkpoint47 rather than with latest
436      checkpoint47f_post since the latter is broken for the adjoint
437      verification/carbon/ contains both ADM and TLM gradient checks.
438    Here they are, before they get changed/lost/stolen.
439    Mostly modif.'s to fix numerical sensitivities.
440    Gradient checks OK for
441    - GM_taper_scheme:
442      * clipping
443      * ac02
444      * linear
445      * glw91
446      * dm95
447      * ldd97
448    - GMREDI_OPTIONS:
449      * GM_VISBECK_VARIABLE_K
450      * GM_NON_UNITY_DIAGONAL
451      * GM_EXTRA_DIAGONAL
452      * GM_BOLUS_ADVEC
453    in conjunction with data.gmredi parameters to be checked in
454    in a few minutes under verification/carbon/code/
455    
456    checkpoint47f_post
457    Merging from release1_p10:
458    o modifications for using pkg/exf with pkg/seaice
459      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
460        and SEAICE_EXTERNAL_FLUXES
461      - pkg/exf CPP options EXF_READ_EVAP and
462        EXF_NO_BULK_COMPUTATIONS
463      - usage examples are Experiments 8 and 9 in
464        verification/lab_sea/README
465      - verification/lab_sea default experiment now uses
466        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
467    
468    checkpoint47e_post
469    o created a tag prior to creating a branch
470    
471    checkpoint47d_post
472    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
473      at the bottom boundary had an erroneous half slip boundary condition
474    o added bottom drag and no slip boundary condition capabilities to
475      oceanic pressure coordinates code
476    o added new verification experiment global_ocean_pressure, this experiment is
477      also described in the tutorial section of the manual
478    checkpoint47d_pre
479    
480    checkpoint47c_post
481    o Added a verification experiment for a global cubed-sphere ocean run
482      -  verification/global_ocean.cubed32x32x30
483      -  uses pkg/therm_seaice and pkg/bulk_forcing
484    
485    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
486    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
487      when using P-coordinate; only implemented for atmospheric config.
488    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
489      NOTES: requires option NONLIN_FRSURF to be "#define".
490    o update advect_xz/results/output.txt (left from checkpoint44g_post)
491    
492    checkpoint47b_post
493    Merging from release1_p9:
494    o pkg/seaice
495      - removed GOTO's and added taf directives
496      - double precision constants to reduce the g77 (Linux)
497        to F77 (SGI) differences reported in release1_p8
498    o tools/genmake
499      - added SGI options
500    o verification/testscript
501      - updated to that of checkpoint47a_post
502    o verification/global_ocean.90x40x15/input/eedata
503      - modified for SGI f77 compatibility
504    o verification/lab_sea
505      - added description of sea-ice model
506      - added missing matlab routines
507      - added test of thermodynamics parallelization
508    
509    checkpoint47a_post
510    o new pkg: aim_v23
511     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
512       for now, keep the same surface forcing as before.
513     - Part-Cell implemented into AIM; check that Heat & Water are conserved
514     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
515     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
516    o add diagnostic of surface correction term in monitor output
517    
518    o bulk_force and therm_seaice
519    - Two packages:  bulk_force (Bulk forcing)
520      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
521    - Earlier integration from Stephaine Dutkiewicz
522      and Patrick Heimbach.
523    - Two ifdef statements for compile time,
524       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
525    
526    checkpoint47
527    differentiable version of checkpoint46n_post
528    o bug fix in quasihydrostaticterms
529    o * "clean" adjoint code (in terms of extensive recomputations)
530        can now be obtained for all GMREDI options (i.e. for
531        - GM_VISBECK_VARIABLE_K
532        - GM_NON_UNITY_DIAGONAL
533        - GM_EXTRA_DIAGONAL
534        - GM_BOLUS_ADVEC )
535      * However, wrong gradient check problem remains unsolved.
536      * New CPP options have been introduced for different
537        tapering schemes
538    o external_fields_load now part of differentiation list
539    o pressure needs multiple storing;
540      would be nice to have store_pressure at beginning or
541      end of forward_step, e.g. by having phiHyd global (5-dim.)
542      (NB: pressure is needed for certain cases in find_rho,
543      which is also invoked through convective_adjustment).
544    o recomputations in find_rho for cases
545     'JMD95'/'UNESCO' or 'MDJWF' are OK.
546    o #define ATMOSPHERIC_LOADING should be differentiable
547    o ini_forcing shifted to begining of initialise_varia
548    o Incorporating QNVS line search routines into MITgcm
549      (this is separate code, and therefore not under pkg)
550      lsopt/, optim/
551    o Updated verification/carbon/
552      - #define GM_VISBECK_VARIABLE_K
553      - GM_taper_scheme    = 'ldd97'    
554    
555    checkpoint46n_post
556    Merging from release1_p8:
557    o verification/natl_box:
558      updating new external_fields_load routine
559    o New package: pkg/seaice
560      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
561      The sea-ice code is based on Hibler (1979-1980).
562      Two sea-ice dynamic solvers, ADI and LSR, are included.
563      In addition to computing prognostic sea-ice variables and diagnosing
564      the forcing/external data fields that drive the ocean model,
565      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
566      The implied surface heat flux is then stored in variable
567      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
568      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
569      non-local transport term.  Because this call precedes model
570      thermodynamics, temperature under sea-ice may not be "exactly" at
571      the freezing point by the time theta is dumped or time-averaged.
572      N.B.: fairly large differences in accuracy occur across
573            different platforms/compilers; comparison between
574            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
575            generated output gives:
576       T           S           U           V
577      C D M    c        m  s        m  s        m  s        m  s
578      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
579      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
580      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
581    
582      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
583    o GAD:
584      - generated new common blocks to account for call of
585        same gad routines with differing traceridentities
586        (needed to modify tracerIdentity indices in GAD.h)
587      - generated separate common blocks for case useCubedSphereExchange
588        (Department of Futurology)
589      - parameter lists to gmredi_?transport: added tracerIdentity
590      - added new key indices to tamc.h
591    o external_fields_load:
592      - added this routine to TAF list
593      - needed to make some common blocks global and additional storing
594        along the same lines as exf package (checkpoint_lev?_directives.h)
595    o exf:
596      updated external forcing package
597      - bug fixes carried over from ecco-branch
598        (missing OBCS_OPTIONS.h in two routines)
599      - enable easy to use "no forcing".
600      - added exf I/O for atmospheric loading
601      - added exf I/O for runoff data
602      - transfered scaling between exf <-> MITgcm to exf namelist
603    o Adding new verification experiment global_with_exf.
604      This verification experiment is almost identical to the
605      global_ocean.90x40x15 experiment, except that it uses
606      the exf (and cal) package instead of the
607      external_fields_load routine (cf README file).
608    
609    checkpoint46m_post
610    o modified testscript to return -- when there are no lines of "%MON" output
611    o added new flag "quasiHydrostatic" for QH mode
612      and new routine quasihydrostaticterms()
613    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
614      New routine: mom_u_coriolis_nh()
615    o fixed sign of non-hydrostatic metric terms in u and v equations.
616      Depend on correct sign of gravitySign.
617    o added work.pc* to .cvsignore in aim directories using ifc
618    o introduced flag for controllin non-hydrostatic metric terms
619    o removed gravitySign from PARM04
620    o switched to g77/ifc from pgf77 in aim experiments
621    
622    checkpoint46l_post
623    o made convective adjustment work with pressure coordinates:
624     - changed the direction of k-loop in convective_adjustment.F for the
625       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
626     - adjusted the reference pressure k-index in convective_adjustment.F
627     - adjusted the convection condition in convect.F (in analogy to
628       calc_ivdc.F)
629     - convective_adjustment no longer computes anything on the halos
630     - removed the warnings about negative salinity from find_rho.F and
631       find_alpha.F; instead the new routine look_for_neg_salinity, called
632       at the beginning of find_rho, find_alpha, and find_beta, does a
633       check of the entire slice, if CPP-option
634       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
635    checkpoint46l_pre
636    
637    checkpoint46k_post
638    o fixed the verification/global_ocean.90x40x15 experiment:
639     - new bathymetry (the world according to A., JMC, and M.)
640     - new initial fields and forcing fields (*.bin files)
641     - new POLY3.COEFFS (for the next release one should switch to a full
642       equation of state: JMD95P or MDJWF)
643     - fixed several errors and redundancies in the data file
644     - experiment uses looped cells
645     - added matlab directory with diagnostic scripts for plotting of output
646    
647    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
648     - read AIM physics parameters from a file (data.aimphys)
649     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
650    
651    checkpoint46j_post
652    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
653    o move wVel computation at the end of the time step, in S/R integr_continuity
654    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
655    o update timeave pkg for wVel diagnostic.
656    checkpoint46j_pre
657    
658    checkpoint46i_post
659    o Clean up AIM package (and keep the results unchanged):
660      include CPP_OPTION and use IMPLICT NONE in all routines ;
661      declare all the variables _RL ; use _d 0 for all numerical constants.
662      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
663    
664    checkpoint46h_post
665    o cleaned up the use of rhoNil and rhoConst.
666      - rhoNil should only appear in the LINEAR equation of state, everywhere
667        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
668        and the dynamical equations are all divided by rhoConst
669    o introduced new parameter rhoConstFresh, a reference density of fresh
670      water, to remove the fresh water flux's dependence on rhoNil. The default
671      value is 999.8 kg/m^3
672    o cleanup up external_forcing.F and external_forcing_surf.F
673      - can now be used by both OCEANIC and OCEANICP
674    checkpoint46h_pre
675    
676     Added code to convert surface volume flux (fresh water) into
677     a mass flux when using P coordinates in the ocean (OCEANICP).
678     Note: It assumes you have set rho0=rhoConst=density of fresh water.
679    
680    checkpoint46g_post
681    o Include a new diagnostic variable phiHydLow for the ocean model
682      - in z-coordinates, it is the bottom pressure anomaly
683      - in p-coordinates, it is the sea surface elevation
684      - in both cases, these variable have global drift, reflecting the mass
685        drift in z-coordinates and the volume drift in p-coordinates
686      - included time averaging for phiHydLow, be aware of the drift!
687    o depth-dependent computation of Bo_surf for pressure coordinates
688      in the ocean (buoyancyRelation='OCEANICP')
689      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
690        Theta, Salinity, and Pressure in the parameter list. This routine is
691        presently contained in find_rho.F. This routine does not give the
692        correct density for 'POLY3', which would be a z-dependent reference
693        density.
694    o cleaned up find_rho
695      - removed obsolete 'eqn' from the parameter list.
696    o added two new verification experiments: gop and goz
697      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
698    checkpoint46g_pre
699    
700    checkpoint46f_post
701    o Enable tangent linear (forward mode) gradient checks:
702      - extended active file handling to g_... files
703      - added TANGENT_SIMULATION to theSimulationMode
704      - extended grdchk package accordingly
705    o added tangent linear setup in verification/carbon/code_ftl
706    o added adjoint setup in verification/front_relax/code_ad
707    
708    checkpoint46e_post
709    o Added new equation of state -> MDJWF
710      - EOS of McDougall et al., 2002, JAOT, submitted
711      - caveat: the equation of state is only valid for a smaller (more
712        realistic?) range of values than JMD95P/Z and UNESCO
713      - added masks to the calculation of pressure in store_pressure
714      - added more check values for density in check_eos (ini_eos.F), some of
715        the old check values are out of the range of the MDJWF-eos, so don't
716        expect perfect matches for those
717    checkpoint46e_pre
718    
719    checkpoint46d_post
720    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
721      'OCEANICP', also initialised field pressure correctly in ini_eos in the
722      case of pressure coordinates. eosType='JMD95Z' in
723      combination with buoyancyRelation='OCEANICP' now causes an error.
724    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
725      in find_alpha/beta.
726    checkpoint46d_pre
727    
728    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
729      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
730    
731    checkpoint46c_post
732    o Changes necessary for ocean in p-coordinates
733     -  Added new buoyancy relation = 'OCEANICP'
734     -  Added new parameters = gravitySign (this used to be contained inside
735        the factor dRdZ which I added when we first switched to R coordinates).
736     X GM/Redi is not compatible (yet)
737     X bottom drag and no-slip need to be debugged.
738    checkpoint46c_pre
739    
740    checkpoint46b_post
741    o Added new equation of state -> JMD95Z and JMD95P
742      - EOS of Jackett and McDougall, 1995, JAOT
743      - moved all EOS parameters into EOS.h
744      - new routines ini_eos.F, store_pressure.F
745    o Added UNESCO EOS, but not recommended because it requires
746      in-situ temperature (see JMD95)
747    o Modified formatting for knudsen2.f in utils/knudsen2 and added
748      unesco.f to be used with POLY3
749    checkpoint46b_pre
750    
751    checkpoint46a_post
752    o Added (atmospheric) pressure loading
753      - new field in FFIELDS.h, etc...
754      - new cpp flag ATMOSPHERIC_LOADING
755    o Changed hFacC to _hFacC in calc_phi_hyd.F
756    o Added SHORTWAVE_HEATING to some files for consistency
757    checkpoint46a_pre
758    
759    checkpoint46
760    further merges from release1_p5
761    o new ctrl package
762      - adopted from ECCO environment to enable optimization
763      - added Eliassen Palm fluxes to controls
764    o added Eliassen Palm flux controls to gradient check package
765    o cost package
766      - Compatible with new ctrl package
767      - added Eliassen Palm cost hooks
768      - modif's of existing cost functions
769    o Adjoint-related bug fixes in kpp:
770      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
771      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
772    o autodiff package
773      - flow directives:
774        + new for S/R do_the_model_io

778        disable adcommon.h/g_common.h by default.
779      - fixed problem for adjoint of global_max
780    o modified verification/carbon/
781    o New setup for adjoint of global_ocean
782    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
783    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
784    o incorporated hooks for sponge layer code (external_forcing.F)
785    
786    checkpoint45d_post
787    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
788    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
789      (affects plume_on_slope "cg2d" output)
790    o add new parameter deltaTfreesurf for free-surface time stepping
791    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
792    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
793    o change phiMin in exp1 (to agree with documentation)
794    o add new flags:
795     - T,S forcing inside/outside Adams-Bashforth
796     - turn off temp,salt advection and/or forcing
797     - for each tracer, define internal flag for multiDimAdvection & A-B
798    o monitor: change definition of KE to check conservation of Energy
799    
800    checkpoint45c_post
801    o Removed f90 comments ("!")
802    o Modified initialisations to enable exf package for MITgcm
803      (without invoking ECCO_PACKAGE).
804    o modifications to gradient check package (Martin Losch)
805      - enable centered differences
806      - modified format of standard output
807    
808    checkpoint45b_post
809    o cleaned exchange calls in cg2d
810    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
811    o included CPP option SINGLE_LAYER_MODE in thermodynamics
812      to configure barotropic setup (Martin Losch)
813    o moved some initialisations within bi,bj loop in dynamics
814      (TAF flow dependency)
815    o in initialise_varia, moved call packages_init_variables
816      before convective_adjustment_init
817      (corresponding adjustment of TAF tape initialisation).
818    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
819    
820    checkpoint45a_post
821    o compute Rho over the whole domain (extend iMin,jMin indices)
822    o specific exchange for X-slice domain (case Ny=1)
823    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
824    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
825    
826    checkpoint44h_post = checkpoint45
827    o Fix to restore differentiability:
828      place at which packages_init_variables is called in
829      initialise_varia is crucial for reverse control flow.
830    o modifications in GMRedi to enable stable adjoint
831      (corresponding modif's in thermodynamics, dynamics)
832    o added missing hook for sponge layer code in external_forcing

838    o modified carbon verif.
839    
840    checkpoint44h_pre
841    o vertical grid option: allow to put the Interface at the middle between

843    o GM Advective form: Tracers are advected using the residual transport (=
844      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
845    
846    checkpoint44g_post
847    o fix surface correction term in multiDimAdvection (affects plume_on_slope
848      results) ; ifdef missing in thermodynamics.F
849    
850    checkpoint44f_pre,checkpoint44f_post
851    o added PTRACERS package
852      This allows an arbitrary number of passive tracers to be integrated
853      forward simultaneously with the dynamicaly model.
854      + Implemented so far:
855        - basic forward algorithm (time-stepping, advection, diffusion, convection)
856        - I/O and checkpointing
857        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
858      + Not implemented so far:
859        - KPP
860        - OBCS
861      + No specific example supplied (yet) but global_ocean.90x40x15 has the
862        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
863        line in data.pkg.
864      + This package is disabled by default since it increases storage.
865    
866    
867    o testscript: added -cleanup option
868    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter

870    
871    checkpoint44e_pre,post
872    o re-wrote convective adjustment to use pre-calculated weights
873      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
874      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
875      Original calls to convect() still in place.
876    
877    chkpt44d_pre,post
878    o added missing EXCLUDE_MONITOR flags
879    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi

882    o in genmake added variable MAKEDEPEND
883      plus resetting for case SunOS
884    o added timer_stats.c routine for IBM SP3
885    o removed variables in dynamics
886    !!! I forgot to create tag chkpt44d_pre !!!
887    !!! But chkpt44d_pre = chkpt44c_post    !!!
888    
889    o real fresh water flux implemented with non-linear free-surface.
890    
891    chkpt44c_pre,post
892    o few fix (mask in shap_s2, EmPmR in external_field_load,
893      USE_NATURAL_BCS in solve_for_P);
894    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
895    
896    checkpoint44b_pre/_post
897    o merge of relevant stuff from the ecco-branch:
898      - genmake: removed $S64 overwrite for case SunOS
899      - pkg/exf: update and corrections for field swapping and obcs
900      - pkg/ecco: parameter lists for the_model_main, the_main_loop

940    
941    checkpoint40
942    o moved calc_gs, calc_gt and calc_tr1 back to model/src
943    o added FLT (floats) package from Arne along with demo. experiment
944    o re-arranged Adams-Bashforth scheme for tracers to allow easier
945      implementation of forward-in-time forcing terms
946    o more mods for non-linear free-surface including new variable
947    o modified multi-dim method to work on cube
948    o bug fix in KPP (from DM)
949    
950    checkpoint40pre9

960    checkpoint40pre8
961    o new package rw/
962      Added method for dumping intermediate local arrays:
963      mdsio_writetile - same as mdsio_writefield except works from inside
964                        bi,bj loop
965      mdsio_writelocal - same as mdsio_writetile except works for local
966                         arrays
967      write_local_r? - higher-level wrapper for mdsio_writelocal
968      Controlled by diagFreq. Defaults to zero (ie. no dumps)
969      Example given at end of mom_vecinv.F that dumps some local arrays.
970    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
971      control flux-form versus vector invariant code.
972      Switch is runtime flag vectorInvariantMomentum (defaults to false)
973      or genmake -DISABLE ...
974    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
975      (additional storing is now needed for case vecinv;
976      currently nothing implemented to switch this storing off
977      in case fluxform is used since no CPP flag available).
978    
979    checkpoint40pre7
980    o bug fix in dynamics.F
981      calc_viscosity called before k=1,Nr loop.

991    o Added diffkr, kapgm to control variables
992    o bug fix in gmredi_slope_limit for ldd97
993    
994    checkpoint40pre5
995    o proper initialization of Adams-Bashforth time stepping
996      + uses forward step for very first step of model (iter=0)
997    o re-generated *all* output since almost all output is modified by this
998      change (sorry but we've been putting this one off for about 2 years)
999      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1000        *not* regenerated since they are already out of date and I don't
1001        want to create the impression that they are suddenly working.
1002    o removed KAP stuff for DEC's
1003    o modified/added many .cvsignore files in */code and */input
1004    o added new expt "solid-body.cs-32x32x1"
1005      + this uses an alternative form of ini_curvilinear_grid.F which
1006        is not necessarily any better than the current one...
1007    
1008    checkpoint40pre4
1009    o added re-initialisations of utrans,vtrans,rtrans in
1010      calc_common_factors which are crucial for TAF.
1011    o extended iMin,jMin range for calc_common_factors,
1012      calc_diffusivity
1013    o added option ALLOW_PASSIVE_TRACER
1014    o a few minor updates and fixes
1015

1018    o split the_main_loop and re-introduced forward_step
1019    o some recomputations of nIter0 for TAMC
1020    
1021    checkpoint40pre2
1022    o Updated to latest branch of AJA, JMC
1023    o Added gradient check package
1024    o Added routines for passive tracer handling
1025    o Added carbon sequestration sensitivity experiment
1026    
1027    checkpoint39

1031       in addummy_in_stepping
1032     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1033     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1034     o Included following packages:
1035       cal: calendar
1036       exf: external forcing
1037       ecco: essential routines to control use of cal, exf
1038             (NB: this is not the full ECCO environment)
1039     o disabled some packages by default in genmake
1040    
1041    checkpoint38
1042     o see notes_c37_adj.txt
1043     o corrected wrong layer index in external_forcing_t
1044     o replaced the_main_loop/forward_step by the_main_loop
1045     o removed forceoutput from write_state
1046       (replaced criteria for initial/final state)
1047     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1048    
1049    checkpoint37
1050     o mdsio.F routine split and packaged in pkg/mdsio
1051       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1052        used unless genmake -disable=mdsio)
1053     o allow a more precise surface-geopotential gradient for the atmosphere
1054       taking into account the change in space of Alpha (=1/rho) at the surface.
1055     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1056       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1057     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1058       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1059       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1060     o Time-Average diagnostics defined as a pseudo package "timeave".
1061     o pickup files : old pickup (before c35) did not work with new code (c35
1062       and after) unless activating 2 commented lines in initialise-varia.
1063     o Non-Hydrostatic pickup file Pb fixed.
1064     o bug with Rigid-lid version (since c35) fixed.  
1065    
1066    checkpoint36
1067     o implement Crank-Nickelson barotropic time-stepping
1068     o recover Time-Average diagnostics
1069     o fix Pb in checkpoint (PR#19)
1070     o AIM become a standard package ; clean unused CPP_kees
1071    
1072    checkpoint35
1073     o subtantial rewrite of dynamics.f
1074     o allows staggered time-stepping
1075     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
1076     o added bottom drag (linear + quadratic)
1077    
1078    checkpoint34
1079     o Modified exchange routines for correct reverse simulation.
1080     o Added verification output to comply with bug fix in impldiff.F
1081       as of c33 (exp2, natl_box).
1082     o Corrected store directives in dynamics.F
1083     o Corrected array boundaries in impldiff.F
1084     o Corrected array dimensions in gmredi.

1087     o Added mdsio_gl.F for ECCO purposes.
1088    
1089    checkpoint33
1090     o Fixed bug in lower BC in impldiff.F
1091     o Fixed confusion about units of forcing arrays in FFIELDS.h
1092       namely Fu,Fv,Qnet,Qsw,EmPmR:
1093       - Removed verification/natl_box/code/external_fields_scale.F
1094         (did not differ from that in model/src)
1095       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
1096         (see FFIELDS.h for description)
1097       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
1098         kpp_calc.F and kpp_transport_t.F
1099       - Removed model/src/external_fields_scale.F and calls to it
1100       - verification/natl_box uses flux data with "atmospheric" sign so
1101         a special version of external_fields_load.F is used to
1102         change the data as it's read in. This way, the arrays
1103         have the right units and signs at all times tha a user could
1104         possibly use them.
1105     o Corrected genmake to delete a temporary file during configuration
1106    
1107    checkpoint32
1108     o Scaling of forcing fields moved from external_forcing.F to
1109       external_fields_scale.F, called directly after loading fields.
1110     o Surface relaxation terms added to surface tendency fields in
1111       extra subroutine.
1112     o impldiff.F changed to avoid storing by TAMC of huge intermediate
1113       fields.
1114     o Changes in GMRedi to comply with packaging structure.
1115     o Modifications and bug fixes in KPP package.
1116     o Verification experiment for KPP added (verification/nat_box/)
1117    
1118    checkpoint31
1119     o Packages interface brought in line with defined standard
1120       -> new routines packages_...F
1121       -> changes in initialise_fixed.F, initialise_varia.F
1122       -> enables initialisation interface for ECCO package
1123     o Rescaling of external forcing fields immediately after read
1124       (removed from external_forcing.F)
1125       -> new: surface_fields_scale.F
1126       -> affects ini_foorcing.F, external_fields_load.F
1127     o Computation of surface tendencies before tendency updates.
1128       -> new: external_forcing_surf.F
1129     o Change of variable names useGMRedi, useKPP, useECCO
1130     o Further changes in dynamics.F, impldiff.F for TAMC
1131     o Tested for experiments 0, 2, 4.
1132       - not yet tested for GMRedi.
1133       - not yet tested for KPP.
1134

1145     o packaged KPP and GM/Redi
1146    
1147    checkpoint28
1148     o Corrected initialization of hFacMin for difference vertical coordinates
1149     o Modified calculation of partial cell thickness to more robust algorithm
1150     o config_summary.F: replaced write_1D_... by write_0D_...
1151       read_write.F: added subroutines write_0D_...
1152     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
1153       included some initialisations required for TAMC.
1154     o routine calc_isoslopes: modified sqrt computation to make it
1155       differentiable for zero argument.
1156     o routines dynamics, impldiff:
1157       included store directives and tape key computations required for TAMC.
1158     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
1159    
1160    checkpoint27
1161     o fixed calc_isoslopes() to so that cancellation of terms in tensor
1162       formulation works properly with variable resolution.
1163     o restructured the calling tree between the_model_main() and dynamics()
1164     o split initialise() into initialise_fixed() and initialise_varia()
1165     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
1166       in new routine ini_psurf()
1167    
1168    checkpoint26
1169     o moved some #ifdef in optional routines to encompass everything
1170       except the argument declarations. This was using up some memory.
1171     o fixed macros like _ADT to work with both versions of Linux cpp
1172     o cleaned up some unused and uninitialized variables
1173       (helps when debugging with strict compile options)
1174     o split up CPP_EEOPTIONS.h into options and macros
1175       (macros are now in eesupp/inc/CPP_EEMACROS.h)
1176     o patch for 2 processor JAM mode
1177    
1178    checkpoint25
1179     o updates for OBCs and NH
1180     o dramatically reduced memory usage

1183     o added a diagnostic of convective index
1184     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
1185       (this is was partly for OBCs and NH but also in anticipation of
1186        an explicit free-surface option)
1187     o initial state input files for U and V
1188    
1189    checkpoint24
1190     o Removed some spurious "REAL"s

1196     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
1197    
1198    checkpoint22
1199     o Made many small changes: implicit none, format(i5), etc...
1200     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
1201    
1202    checkpoint21
1203     o Introduced new I/O package that supports direct-access records (mdsio.F)
1204     o Split-up mid-level I/O routines
1205     o Updated input data for experiments 0,1,2,4 and 5

1234     o Minor changes to exchange routines to support
1235       accumulation in reverse mode. Adjoint of an
1236       assignment is an addition.
1237     o Changes to support compilation by TAMC (LR(1)
1238       syntax) and by g77 under Linux ( 72 character
1239       limit ).
1240    
1241    checkpoint15
1242     Rewrote exchange routines to allow
1243     o General tile <-> tile connectivity.
1244     o TAMC reverse mode flag ( is this really needed? )
1245     o Variable width overlap and exchange region widths.
1246     o Hooks for sharing data via DMA, Arctic, Memory Channel,
1247       shmput/shmget, VIA, SYSV shmem and every other cool
1248       communication method.
1249    
1250    checkpoint14
1251     Consistent isomorphism chages made. These allow dynamical core

1253    
1254    checkpoint13
1255     Release which corrects global_max problem and a couple
1256     of KGM time-averaging diagnostic errors. Also contains
1257     a double-gyre experiment setup as well as the baseline
1258     4 degree global template. The double gyre template is
1259     organised to allow it to be applied automatically to
1260     the baseline configuration.

1263     A few tidy-ups have been made bt the real point of this
1264     check-point (excuse the pun) is to allow a branch to be
1265     made for the purposes of adding the rDot alterations.
1266     I don't want to commit the rDot to the main-trunk until
1267     we've actually tested it...
1268    
1269    checkpoint12
1270     Tidy up and added generic genmake script (formerly
1271     configure script).
1272     Released to testers.
1273    
1274    checkpoint11
1275     Re-arranged initialise() and introduced ini_vertical_grid()
1276     and ini_masks_etc().
1277    
1278    checkpoint10
1279     Introduced the configure script.
1280     Separated out the diags package.
1281     Added template for writing time-averages of tile/intermediate quantities.
1282     Updated SIZE.h in exp2 and made the data big-endian.
1283    
1284    checkpoint9
1285     MPI fix. Filename changes (meta/data). salbin*y stuff.
1286     General tidy-up.
1287     SST.bin SSS.bin added to verification/exp2
1288

1290     Inludes time-dependant forcing and time-averaging.
1291     Works at 4x4 and 2.8125x2.8125 global
1292    
1293    checkpoint7-4degree-ref
1294     Branch from checkpoint7. Released for application to
1295     global modeling and general modeling - process studies, regional
1296     model etc..
1297     Configured for verification/exp2 - 4 degree global, two process.
