73    o modify code for biogeo packages
74      - in model/src and pkg/ptracers
75    
76    checkpoint51
77    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
78      - autodiff, ctrl, exf, grdchk, seaice
79      kept separate packages
80      - cost, ecco, obcs
81    o updating verification/internal_wave, verification/lab_sea
82      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
83    
84    checkpoint50i_post
85    o Preparing next differentiable checkpoint and sync
86      of MAIN vs. ecco-branch
87      - 1st step: this one is differentiable
88      - 2nd step: next(! not this) checkpoint will have updated packages
89                  from ecco-branch)
90    
91    checkpoint50h_post
92    o new package "land": provide surface BC for AIM.
93    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
94    o AIM: use true log-P extrapolation for near surface temp (= as in
95        F.Molteni paper) ; update aim.5l_cs output.
96    o New variable in PARM03 for more flexible pickups
97    o somewhat cleaned package initialisation sequence for
98      ctrl/ cost/ ecco/ in packages_... routines
99    
100    checkpoint50g_post
101    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
102      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
103      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
104        made the default because of faster convergence than ADI
105    
106    checkpoint50f_post
107    o exf totally restructured
108      - replaced all exf_set_ routines by one generic exf_set_gen.F
109        and made sure it's still differentiable
110      - split exf_getffields.F into new exf_bulkformulae.F
111      - exf_inscal_/exf_outscal_ suffixes consistent with field names

121     o new fn in pkg/monitor to stop model if solution grows too big
122     o removed lots of single quotes from comments
123    
124    checkpoint50e_post
125    o make KPP work with PTRACERS
126     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
127       nearly a copy of kpp_transport_s
128     - there is no analogue to SurfaceTendencyS, so I have to use
129       gPtr(of the surface layer) instead
130    o add a new platform SunFire+mpi (SunFire 15000) to genmake
131    checkpoint50e_pre
132    
133    checkpoint50d_post
134    o change kpp output from multiple-record state files to single-record state
135      files analogous to write_state.F
136    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
137      analogous to the cg2d-related output.
138    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
139      so that writing to internal file fn (with length 512) fails.
140    checkpoint50d_pre
141    
142    checkpoint50c_post
143    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
144    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
145    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
146    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
147    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
148    
149    checkpoint50c_pre
150    Merging from release1_p13:
151    o bug fix for pkg/seaice dynamic solver
152    o Added SEAICE_initialHEFF to pkg/seaice
153    
154    checkpoint50b_post
155    o store u*,v* in gU,V instead of in guNm1,gvNm1
156    o in order to put the momForcing out of the Adams-Bashforth:
157      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
158      to timestep.F
159    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
160    o re-generate output for highly sensitive test-exp:
161       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
162    
163    checkpoint50b_pre
164    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
165    o corrected CPP option mismatch in exf_Bulk... functions for case
166      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
167    
168    checkpoint50a_post
169    o Bug fix for merging between c50 and KPP.
170      ikey was passed from thermodynamics to kpp_calc via
171      common block rather than being recomputed in kpp_calc,
172      in contradiction with new key itdkey.
173      New key ikppkey created, and tamc.h headers updated.
174    
175    checkpoint50
176    - 2nd step of merge with ecco-branch:
177      merge changes in ecco-branch back into main trunk
178    - bug fix in find_alpha
179    - more storing in gmredi_calc_tensor.F, kpp_routines.F
180    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
181    - merged some sliced AD support routines
182    
183    checkpoint49
184    merged from ecco-branch:
185    o exf:
186      - Enable initialisation of forcing fields to constant
187        (runtime) values.
188      - in exf_getffields.F
189        Reduce i-/j-loop to interior domain, discarding overlaps.
190        That also fixes wrong TAF-key computations for key_1, key_2
191        with bulf formulae.
192      - exf_init.F modify #ifdef for exf_init_evap
193      - exf_getffieldrec.F, ctrl_getrec.F
194        The following INT-usages are not safe:
195          fldsecs  = int(fldsecs/fldperiod)*fldperiod
196          fldcount = int(fldsecs/fldperiod) + 1
197        and were modified.
198    o autodiff: checkpoint_lev...
199      - updated storing for bulk formulae (some arrays were missing)
200      - added state for seaice package
201      - synchronized with main branch
202    o DIVA:
203      Modif.s in
204      - the_main_loop.F
205      - the_model_main.F
206      and added cost_final_restore.F cost_final_store.F
207      o With these changes, it is possible to fully separate
208        the first forward run to compute the cost function (mdthe_main_loop)
209        and adjoint runs over individual DIVA intervals (adthe_main_loop)
210        into separate model executions.
211        This enables better tuning of DIVA to given queue sizes.
212      o Loss of cost function value in consecutive DIVA runs is
213        fixed by storing to 'costfinal' file.
214      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
215        beginning/end of adjoint integration is accounted for.
216      The current changes apply to TAF-1.4.26.
217      TAF has one remaining bug, requiring one manual change
218      (see MITgcm manual).
219    o cal: synchronized between MAIN and ecco-branch
220    
221    checkpoint48i_post
222    o Changes to restore differentiability of code w.r.t. previous tag
223      (mostly adding new routines to make list and replacing
224      pressure by totPhiHyd).
225    o Updated and merged grdchk package
226      - has both ADM and TLM checks
227      - works for single- and multi-proc.
228      - output cleaned
229      - worked successfully for parallel DIVA
230    o genmake:
231      - Adding -platform=SP4
232      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
233    o Modif. for DIVA:
234      ctrl_unpack should not be called in intermediate DIVA interval.
235      (similar thing would apply for active files such as
236      tbar, sbar, psbar, which should not be reinitialised;
237      only relevant for ecco-branch)
238    
239    checkpoint48h_post
240    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
241    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
242    o Added SEAICE_initialHEFF to pkg/seaice
243    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
244    
245    checkpoint48g_post
246    --- EOS:
247    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
248      store total Potential in totPhyHyd for diagnostics & EOS.
249    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
250    --- Pressure/geopotential gradient:
251    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
252    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
253      ( changes results of global_ocean_pressure )
254    o NLFS + z-coord.: add eta*Rho' contribution.
255    o accurate phiHyd when using interface-W at the middle between 2 centers
256     ( changes results of ideal_2D_oce )
257    o includes r* 2nd term in potential gradient.
258    
259    checkpoint48f_post
260    Merging from release1_p12:
261    o Modifications for using pkg/exf with pkg/seaice
262      - improved description of the various forcing configurations
263      - added basic radiation bulk formulae to pkg/exf
264      - units/sign fix for evap computation in exf_getffields.F
265      - updated verification/global_with_exf/results/output.txt
266    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
267      (SBO) core products, including oceanic mass, center-of-mass,
268      angular, and bottom pressure (see pkg/sbo/README.sbo).
269    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
270      to avoid negative values in shallow regions.
271      - updated verification/natl_box/results/output.txt
272      - updated verification/lab_sea/results/output.txt
273    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
274    o Added useSingleCpuIO option (see PARAMS.h).
275    o Updated useSingleCpuIO option in mdsio_writefield.F to
276      work with multi-field files, e.g., for single-file pickup.
277    o pkg/seaice:
278      - bug fix in growth.F: QNET for no shortwave case
279      - added HeffFile for specifying initial sea-ice thickness
280      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
281    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
282      kpp_transport_t.F, forward_step.F, and the_main_loop.F
283    o pkg/seaice:
284      - adjoint-friendly modifications
285      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
286    
287    checkpoint48e_post
288    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
289    o dynamics: change definition of computational domain & adapt mom_fluxform
290      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
291    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
292        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
293        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
294        global_ocean.90x40x15 global_with_exf global_ocean_pressure
295        inverted_barometer solid-body.cs-32x32x1
296      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
297    
298    checkpoint48d_post
299    o in preparation for r*:
300     a) use pre-computed gradient of hydrostatic potential:
301        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
302     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
303        => affects results of glob_oce_pressure (different truncation error)  
304      update output.txt of ideal_2D_oce & global_ocean_pressure
305    
306    checkpoint48d_pre
307    o in preparation for r*:
308      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
309      pass the 2 comp. of the grad. as arguments to momentum S/R.
310      but for the moment, only used if it does not change the results.
311    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
312    
313    checkpoint48c_post
314    Modifications in treatment of initial flux forcing controls
315    to avoid extra storing of flux fields.
316    
317    checkpoint48c_pre
318    o Added tidal_basin_2d experiment (currently 1D!)
319    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
320    
321    checkpoint48b_post
322    o r* coordinate added in #ifdef NONLIN_FRSURF block.
323     (modification to pressure gradient not yet implemented)
324    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
325      (for U & V) that are used for vertical advection of momentum.
326    
327    checkpoint48a_post
328    o In preparation for r*, use temp. array to compute vertical transport
329       in flux-form momentum pkg. => change results of few test-exp.
330      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
331                        lab_sea, natl_box & plume_on_slope
332    
333    checkpoint48
334    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
335    
336    checkpoint47j_post
337    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
338    o moved adexch from forward_step to addummy_in_stepping
339    o added exch in ctrl_map_...
340    o aveFreq.=0. at end of cost_final to avoid overwrite in
341      reverse checkpointing loop
342    o Yet more changes in gmredi:
343      * adgmredi_calc_tensor
344        avoiding all recomputation of gmredi_slope_limit
345      * adgmredi_x/y/rtransport
346        added flag for excessive storing to avoid recomp. of
347        u/v/rtans, dTdx/y/z
348        -> this is not really necessary and very memory-consuming
349      * adgmredi_slope_psi:
350        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
351      * gmredi_slope_limit
352        re-activated full calculation of taperfct for case 'ac02'
353    o updating verification/ adjoints of carbon, global_ocean.90x40x15
354    
355    checkpoint47i_post
356    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
357    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
358      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
359    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
360    o gmredi: fix few bugs.
361    
362    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
363    This will be a good checkpoint to plug into the ecco-branch.
364    o few modif.'s to get latest version adjointed
365      (mainly kick out code in ini_linear_phisurf)
366    o modif's to run adjoint with exactConserv
367    o case GM_BOLUS_ADVEC should be cleaned
368      S/R gmredi_slope_psi should be cleaned
369    o verification/carbon now has exactConserv=.TRUE.
370    
371    checkpoint47g_post
372    o time-average AIM output: becomes independent from statvars time-average
373      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
374    o After TAF bug fix:
375      Tested adjoint of gmredi package.
376      Tests were done with checkpoint47 rather than with latest
377      checkpoint47f_post since the latter is broken for the adjoint
378      verification/carbon/ contains both ADM and TLM gradient checks.
379    Here they are, before they get changed/lost/stolen.
380    Mostly modif.'s to fix numerical sensitivities.
381    Gradient checks OK for
382    - GM_taper_scheme:
383      * clipping
384      * ac02
385      * linear
386      * glw91
387      * dm95
388      * ldd97
389    - GMREDI_OPTIONS:
390      * GM_VISBECK_VARIABLE_K
391      * GM_NON_UNITY_DIAGONAL
392      * GM_EXTRA_DIAGONAL
393      * GM_BOLUS_ADVEC
394    in conjunction with data.gmredi parameters to be checked in
395    in a few minutes under verification/carbon/code/
396    
397    checkpoint47f_post
398    Merging from release1_p10:
399    o modifications for using pkg/exf with pkg/seaice
400      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
401        and SEAICE_EXTERNAL_FLUXES
402      - pkg/exf CPP options EXF_READ_EVAP and
403        EXF_NO_BULK_COMPUTATIONS
404      - usage examples are Experiments 8 and 9 in
405        verification/lab_sea/README
406      - verification/lab_sea default experiment now uses
407        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
408    
409    checkpoint47e_post
410    o created a tag prior to creating a branch
411    
412    checkpoint47d_post
413    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
414      at the bottom boundary had an erroneous half slip boundary condition
415    o added bottom drag and no slip boundary condition capabilities to
416      oceanic pressure coordinates code
417    o added new verification experiment global_ocean_pressure, this experiment is
418      also described in the tutorial section of the manual
419    checkpoint47d_pre
420    
421    checkpoint47c_post
422    o Added a verification experiment for a global cubed-sphere ocean run
423      -  verification/global_ocean.cubed32x32x30
424      -  uses pkg/therm_seaice and pkg/bulk_forcing
425    
426    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
427    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
428      when using P-coordinate; only implemented for atmospheric config.
429    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
430      NOTES: requires option NONLIN_FRSURF to be "#define".
431    o update advect_xz/results/output.txt (left from checkpoint44g_post)
432    
433    checkpoint47b_post
434    Merging from release1_p9:
435    o pkg/seaice
436      - removed GOTO's and added taf directives
437      - double precision constants to reduce the g77 (Linux)
438        to F77 (SGI) differences reported in release1_p8
439    o tools/genmake
440      - added SGI options
441    o verification/testscript
442      - updated to that of checkpoint47a_post
443    o verification/global_ocean.90x40x15/input/eedata
444      - modified for SGI f77 compatibility
445    o verification/lab_sea
446      - added description of sea-ice model
447      - added missing matlab routines
448      - added test of thermodynamics parallelization
449    
450    checkpoint47a_post
451    o new pkg: aim_v23
452     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
453       for now, keep the same surface forcing as before.
454     - Part-Cell implemented into AIM; check that Heat & Water are conserved
455     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
456     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
457    o add diagnostic of surface correction term in monitor output
458    
459    o bulk_force and therm_seaice
460    - Two packages:  bulk_force (Bulk forcing)
461      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
462    - Earlier integration from Stephaine Dutkiewicz
463      and Patrick Heimbach.
464    - Two ifdef statements for compile time,
465       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
466    
467    checkpoint47
468    differentiable version of checkpoint46n_post
469    o bug fix in quasihydrostaticterms
470    o * "clean" adjoint code (in terms of extensive recomputations)
471        can now be obtained for all GMREDI options (i.e. for
472        - GM_VISBECK_VARIABLE_K
473        - GM_NON_UNITY_DIAGONAL
474        - GM_EXTRA_DIAGONAL
475        - GM_BOLUS_ADVEC )
476      * However, wrong gradient check problem remains unsolved.
477      * New CPP options have been introduced for different
478        tapering schemes
479    o external_fields_load now part of differentiation list
480    o pressure needs multiple storing;
481      would be nice to have store_pressure at beginning or
482      end of forward_step, e.g. by having phiHyd global (5-dim.)
483      (NB: pressure is needed for certain cases in find_rho,
484      which is also invoked through convective_adjustment).
485    o recomputations in find_rho for cases
486     'JMD95'/'UNESCO' or 'MDJWF' are OK.
487    o #define ATMOSPHERIC_LOADING should be differentiable
488    o ini_forcing shifted to begining of initialise_varia
489    o Incorporating QNVS line search routines into MITgcm
490      (this is separate code, and therefore not under pkg)
491      lsopt/, optim/
492    o Updated verification/carbon/
493      - #define GM_VISBECK_VARIABLE_K
494      - GM_taper_scheme    = 'ldd97'    
495    
496    checkpoint46n_post
497    Merging from release1_p8:
498    o verification/natl_box:
499      updating new external_fields_load routine
500    o New package: pkg/seaice
501      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
502      The sea-ice code is based on Hibler (1979-1980).
503      Two sea-ice dynamic solvers, ADI and LSR, are included.
504      In addition to computing prognostic sea-ice variables and diagnosing
505      the forcing/external data fields that drive the ocean model,
506      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
507      The implied surface heat flux is then stored in variable
508      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
509      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
510      non-local transport term.  Because this call precedes model
511      thermodynamics, temperature under sea-ice may not be "exactly" at
512      the freezing point by the time theta is dumped or time-averaged.
513      N.B.: fairly large differences in accuracy occur across
514            different platforms/compilers; comparison between
515            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
516            generated output gives:
517       T           S           U           V
518      C D M    c        m  s        m  s        m  s        m  s
519      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
520      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d

522    
523      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
524    o GAD:
525      - generated new common blocks to account for call of
526        same gad routines with differing traceridentities
527        (needed to modify tracerIdentity indices in GAD.h)
528      - generated separate common blocks for case useCubedSphereExchange
529        (Department of Futurology)
530      - parameter lists to gmredi_?transport: added tracerIdentity
531      - added new key indices to tamc.h
532    o external_fields_load:
533      - added this routine to TAF list
534      - needed to make some common blocks global and additional storing
535        along the same lines as exf package (checkpoint_lev?_directives.h)
536    o exf:
537      updated external forcing package
538      - bug fixes carried over from ecco-branch
539        (missing OBCS_OPTIONS.h in two routines)
540      - enable easy to use "no forcing".
541      - added exf I/O for atmospheric loading
542      - added exf I/O for runoff data
543      - transfered scaling between exf <-> MITgcm to exf namelist
544    o Adding new verification experiment global_with_exf.
545      This verification experiment is almost identical to the
546      global_ocean.90x40x15 experiment, except that it uses
547      the exf (and cal) package instead of the
548      external_fields_load routine (cf README file).
549    
550    checkpoint46m_post
551    o modified testscript to return -- when there are no lines of "%MON" output
552    o added new flag "quasiHydrostatic" for QH mode
553      and new routine quasihydrostaticterms()
554    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
555      New routine: mom_u_coriolis_nh()
556    o fixed sign of non-hydrostatic metric terms in u and v equations.
557      Depend on correct sign of gravitySign.
558    o added work.pc* to .cvsignore in aim directories using ifc
559    o introduced flag for controllin non-hydrostatic metric terms
560    o removed gravitySign from PARM04
561    o switched to g77/ifc from pgf77 in aim experiments
562    
563    checkpoint46l_post
564    o made convective adjustment work with pressure coordinates:
565     - changed the direction of k-loop in convective_adjustment.F for the
566       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
567     - adjusted the reference pressure k-index in convective_adjustment.F
568     - adjusted the convection condition in convect.F (in analogy to
569       calc_ivdc.F)
570     - convective_adjustment no longer computes anything on the halos
571     - removed the warnings about negative salinity from find_rho.F and
572       find_alpha.F; instead the new routine look_for_neg_salinity, called
573       at the beginning of find_rho, find_alpha, and find_beta, does a
574       check of the entire slice, if CPP-option
575       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
576    checkpoint46l_pre
577    
578    checkpoint46k_post
579    o fixed the verification/global_ocean.90x40x15 experiment:
580     - new bathymetry (the world according to A., JMC, and M.)
581     - new initial fields and forcing fields (*.bin files)
582     - new POLY3.COEFFS (for the next release one should switch to a full
583       equation of state: JMD95P or MDJWF)
584     - fixed several errors and redundancies in the data file
585     - experiment uses looped cells
586     - added matlab directory with diagnostic scripts for plotting of output
587    
588    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
589     - read AIM physics parameters from a file (data.aimphys)
590     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
591    
592    checkpoint46j_post
593    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
594    o move wVel computation at the end of the time step, in S/R integr_continuity
595    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
596    o update timeave pkg for wVel diagnostic.
597    checkpoint46j_pre
598    
599    checkpoint46i_post
600    o Clean up AIM package (and keep the results unchanged):
601      include CPP_OPTION and use IMPLICT NONE in all routines ;
602      declare all the variables _RL ; use _d 0 for all numerical constants.
603      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
604    
605    checkpoint46h_post
606    o cleaned up the use of rhoNil and rhoConst.
607      - rhoNil should only appear in the LINEAR equation of state, everywhere
608        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
609        and the dynamical equations are all divided by rhoConst
610    o introduced new parameter rhoConstFresh, a reference density of fresh
611      water, to remove the fresh water flux's dependence on rhoNil. The default
612      value is 999.8 kg/m^3
613    o cleanup up external_forcing.F and external_forcing_surf.F
614      - can now be used by both OCEANIC and OCEANICP
615    checkpoint46h_pre
616    
617     Added code to convert surface volume flux (fresh water) into
618     a mass flux when using P coordinates in the ocean (OCEANICP).
619     Note: It assumes you have set rho0=rhoConst=density of fresh water.
620    
621    checkpoint46g_post
622    o Include a new diagnostic variable phiHydLow for the ocean model
623      - in z-coordinates, it is the bottom pressure anomaly
624      - in p-coordinates, it is the sea surface elevation
625      - in both cases, these variable have global drift, reflecting the mass
626        drift in z-coordinates and the volume drift in p-coordinates
627      - included time averaging for phiHydLow, be aware of the drift!
628    o depth-dependent computation of Bo_surf for pressure coordinates
629      in the ocean (buoyancyRelation='OCEANICP')
630      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
631        Theta, Salinity, and Pressure in the parameter list. This routine is
632        presently contained in find_rho.F. This routine does not give the
633        correct density for 'POLY3', which would be a z-dependent reference
634        density.
635    o cleaned up find_rho
636      - removed obsolete 'eqn' from the parameter list.
637    o added two new verification experiments: gop and goz
638      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
639    checkpoint46g_pre
640    
641    checkpoint46f_post
642    o Enable tangent linear (forward mode) gradient checks:
643      - extended active file handling to g_... files
644      - added TANGENT_SIMULATION to theSimulationMode
645      - extended grdchk package accordingly
646    o added tangent linear setup in verification/carbon/code_ftl
647    o added adjoint setup in verification/front_relax/code_ad
648    
649    checkpoint46e_post
650    o Added new equation of state -> MDJWF
651      - EOS of McDougall et al., 2002, JAOT, submitted
652      - caveat: the equation of state is only valid for a smaller (more
653        realistic?) range of values than JMD95P/Z and UNESCO
654      - added masks to the calculation of pressure in store_pressure
655      - added more check values for density in check_eos (ini_eos.F), some of
656        the old check values are out of the range of the MDJWF-eos, so don't
657        expect perfect matches for those
658    checkpoint46e_pre
659    
660    checkpoint46d_post
661    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
662      'OCEANICP', also initialised field pressure correctly in ini_eos in the
663      case of pressure coordinates. eosType='JMD95Z' in
664      combination with buoyancyRelation='OCEANICP' now causes an error.
665    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
666      in find_alpha/beta.
667    checkpoint46d_pre
668    
669    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
670      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
671    
672    checkpoint46c_post
673    o Changes necessary for ocean in p-coordinates
674     -  Added new buoyancy relation = 'OCEANICP'
675     -  Added new parameters = gravitySign (this used to be contained inside
676        the factor dRdZ which I added when we first switched to R coordinates).
677     X GM/Redi is not compatible (yet)
678     X bottom drag and no-slip need to be debugged.
679    checkpoint46c_pre
680    
681    checkpoint46b_post
682    o Added new equation of state -> JMD95Z and JMD95P
683      - EOS of Jackett and McDougall, 1995, JAOT
684      - moved all EOS parameters into EOS.h
685      - new routines ini_eos.F, store_pressure.F
686    o Added UNESCO EOS, but not recommended because it requires
687      in-situ temperature (see JMD95)
688    o Modified formatting for knudsen2.f in utils/knudsen2 and added
689      unesco.f to be used with POLY3
690    checkpoint46b_pre
691    
692    checkpoint46a_post
693    o Added (atmospheric) pressure loading
694      - new field in FFIELDS.h, etc...
695      - new cpp flag ATMOSPHERIC_LOADING
696    o Changed hFacC to _hFacC in calc_phi_hyd.F
697    o Added SHORTWAVE_HEATING to some files for consistency
698    checkpoint46a_pre
699    
700    checkpoint46
701    further merges from release1_p5
702    o new ctrl package
703      - adopted from ECCO environment to enable optimization
704      - added Eliassen Palm fluxes to controls
705    o added Eliassen Palm flux controls to gradient check package
706    o cost package
707      - Compatible with new ctrl package
708      - added Eliassen Palm cost hooks
709      - modif's of existing cost functions
710    o Adjoint-related bug fixes in kpp:
711      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
712      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
713    o autodiff package
714      - flow directives:
715        + new for S/R do_the_model_io
716        + enhanced for S/R checkpoint
717        + new gmredi.flow
718      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
719        disable adcommon.h/g_common.h by default.
720      - fixed problem for adjoint of global_max
721    o modified verification/carbon/
722    o New setup for adjoint of global_ocean
723    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
724    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
725    o incorporated hooks for sponge layer code (external_forcing.F)
726    
727    checkpoint45d_post
728    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
729    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
730      (affects plume_on_slope "cg2d" output)
731    o add new parameter deltaTfreesurf for free-surface time stepping
732    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
733    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
734    o change phiMin in exp1 (to agree with documentation)
735    o add new flags:
736     - T,S forcing inside/outside Adams-Bashforth
737     - turn off temp,salt advection and/or forcing
738     - for each tracer, define internal flag for multiDimAdvection & A-B
739    o monitor: change definition of KE to check conservation of Energy
740    
741    checkpoint45c_post
742    o Removed f90 comments ("!")
743    o Modified initialisations to enable exf package for MITgcm
744      (without invoking ECCO_PACKAGE).
745    o modifications to gradient check package (Martin Losch)
746      - enable centered differences
747      - modified format of standard output
748    
749    checkpoint45b_post
750    o cleaned exchange calls in cg2d
751    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
752    o included CPP option SINGLE_LAYER_MODE in thermodynamics
753      to configure barotropic setup (Martin Losch)
754    o moved some initialisations within bi,bj loop in dynamics
755      (TAF flow dependency)
756    o in initialise_varia, moved call packages_init_variables
757      before convective_adjustment_init
758      (corresponding adjustment of TAF tape initialisation).
759    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
760    
761    checkpoint45a_post
762    o compute Rho over the whole domain (extend iMin,jMin indices)
763    o specific exchange for X-slice domain (case Ny=1)
764    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
765    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
766    
767    checkpoint44h_post = checkpoint45
768    o Fix to restore differentiability:
769      place at which packages_init_variables is called in
770      initialise_varia is crucial for reverse control flow.
771    o modifications in GMRedi to enable stable adjoint
772      (corresponding modif's in thermodynamics, dynamics)
773    o added missing hook for sponge layer code in external_forcing
774    o modified test cost functions
775    o storing in gad_advection (plus removal of write(0,*)!
776    o missing headers TR1.h added in convective_adjustment routines
777    o errorMessageUnit set non-equal zero in eeboot
778      (conflict on some platforms, e.g. IBM SP3)
779    o modified carbon verif.
780    
781    checkpoint44h_pre
782    o vertical grid option: allow to put the Interface at the middle between
783      2 cell-centers ; replace delZ in pkg/kpp by drF.
784    o GM Advective form: Tracers are advected using the residual transport (=
785      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
786    
787    checkpoint44g_post
788    o fix surface correction term in multiDimAdvection (affects plume_on_slope
789      results) ; ifdef missing in thermodynamics.F
790    
791    checkpoint44f_pre,checkpoint44f_post
792    o added PTRACERS package
793      This allows an arbitrary number of passive tracers to be integrated
794      forward simultaneously with the dynamicaly model.
795      + Implemented so far:
796        - basic forward algorithm (time-stepping, advection, diffusion, convection)
797        - I/O and checkpointing
798        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
799      + Not implemented so far:
800        - KPP
801        - OBCS
802      + No specific example supplied (yet) but global_ocean.90x40x15 has the
803        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
804        line in data.pkg.
805      + This package is disabled by default since it increases storage.
806    
807    
808    o testscript: added -cleanup option
809    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
810                 b) enable to filter 2D fields.
811    
812    checkpoint44e_pre,post
813    o re-wrote convective adjustment to use pre-calculated weights
814      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
815      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
816      Original calls to convect() still in place.
817    
818    chkpt44d_pre,post
819    o added missing EXCLUDE_MONITOR flags
820    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
821      (incompatible typ in MIN/MAX expressions caused problems
822      on IBM SP3)
823    o in genmake added variable MAKEDEPEND
824      plus resetting for case SunOS
825    o added timer_stats.c routine for IBM SP3
826    o removed variables in dynamics
827    !!! I forgot to create tag chkpt44d_pre !!!
828    !!! But chkpt44d_pre = chkpt44c_post    !!!

881    
882    checkpoint40
883    o moved calc_gs, calc_gt and calc_tr1 back to model/src
884    o added FLT (floats) package from Arne along with demo. experiment
885    o re-arranged Adams-Bashforth scheme for tracers to allow easier

904      mdsio_writetile - same as mdsio_writefield except works from inside
905                        bi,bj loop
906      mdsio_writelocal - same as mdsio_writetile except works for local
907                         arrays
908      write_local_r? - higher-level wrapper for mdsio_writelocal
909      Controlled by diagFreq. Defaults to zero (ie. no dumps)
910      Example given at end of mom_vecinv.F that dumps some local arrays.
911    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
912      control flux-form versus vector invariant code.
913      Switch is runtime flag vectorInvariantMomentum (defaults to false)
914      or genmake -DISABLE ...
915    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
916      (additional storing is now needed for case vecinv;
917      currently nothing implemented to switch this storing off

932    o Added diffkr, kapgm to control variables
933    o bug fix in gmredi_slope_limit for ldd97
934    
935    checkpoint40pre5
936    o proper initialization of Adams-Bashforth time stepping
937      + uses forward step for very first step of model (iter=0)
938    o re-generated *all* output since almost all output is modified by this
939      change (sorry but we've been putting this one off for about 2 years)
940      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
941        *not* regenerated since they are already out of date and I don't
942        want to create the impression that they are suddenly working.
943    o removed KAP stuff for DEC's
944    o modified/added many .cvsignore files in */code and */input
945    o added new expt "solid-body.cs-32x32x1"
946      + this uses an alternative form of ini_curvilinear_grid.F which
947        is not necessarily any better than the current one...
948    
949    checkpoint40pre4
950    o added re-initialisations of utrans,vtrans,rtrans in
951      calc_common_factors which are crucial for TAF.

974     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
975     o Included following packages:
976       cal: calendar
977       exf: external forcing
978       ecco: essential routines to control use of cal, exf
979             (NB: this is not the full ECCO environment)
980     o disabled some packages by default in genmake
981    
982    checkpoint38
983     o see notes_c37_adj.txt

988     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
989    
990    checkpoint37
991     o mdsio.F routine split and packaged in pkg/mdsio
992       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
993        used unless genmake -disable=mdsio)
994     o allow a more precise surface-geopotential gradient for the atmosphere
995       taking into account the change in space of Alpha (=1/rho) at the surface.
996     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
997       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
998     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
999       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1000       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1001     o Time-Average diagnostics defined as a pseudo package "timeave".
1002     o pickup files : old pickup (before c35) did not work with new code (c35
1003       and after) unless activating 2 commented lines in initialise-varia.
1004     o Non-Hydrostatic pickup file Pb fixed.
1005     o bug with Rigid-lid version (since c35) fixed.  
1006    
1007    checkpoint36
1008     o implement Crank-Nickelson barotropic time-stepping
1009     o recover Time-Average diagnostics
1010     o fix Pb in checkpoint (PR#19)
1011     o AIM become a standard package ; clean unused CPP_kees
1012    
1013    checkpoint35
1014     o subtantial rewrite of dynamics.f
1015     o allows staggered time-stepping
1016     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
1017     o added bottom drag (linear + quadratic)
1018    
1019    checkpoint34
1020     o Modified exchange routines for correct reverse simulation.
1021     o Added verification output to comply with bug fix in impldiff.F
1022       as of c33 (exp2, natl_box).
1023     o Corrected store directives in dynamics.F
1024     o Corrected array boundaries in impldiff.F
1025     o Corrected array dimensions in gmredi.

1029    
1030    checkpoint33
1031     o Fixed bug in lower BC in impldiff.F
1032     o Fixed confusion about units of forcing arrays in FFIELDS.h
1033       namely Fu,Fv,Qnet,Qsw,EmPmR:
1034       - Removed verification/natl_box/code/external_fields_scale.F
1035         (did not differ from that in model/src)
1036       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
1037         (see FFIELDS.h for description)
1038       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
1039         kpp_calc.F and kpp_transport_t.F
1040       - Removed model/src/external_fields_scale.F and calls to it
1041       - verification/natl_box uses flux data with "atmospheric" sign so
1042         a special version of external_fields_load.F is used to
1043         change the data as it's read in. This way, the arrays
1044         have the right units and signs at all times tha a user could
1045         possibly use them.
1046     o Corrected genmake to delete a temporary file during configuration
1047    
1048    checkpoint32
1049     o Scaling of forcing fields moved from external_forcing.F to
1050       external_fields_scale.F, called directly after loading fields.
1051     o Surface relaxation terms added to surface tendency fields in
1052       extra subroutine.
1053     o impldiff.F changed to avoid storing by TAMC of huge intermediate
1054       fields.
1055     o Changes in GMRedi to comply with packaging structure.

1059    checkpoint31
1060     o Packages interface brought in line with defined standard
1061       -> new routines packages_...F
1062       -> changes in initialise_fixed.F, initialise_varia.F
1063       -> enables initialisation interface for ECCO package
1064     o Rescaling of external forcing fields immediately after read
1065       (removed from external_forcing.F)
1066       -> new: surface_fields_scale.F
1067       -> affects ini_foorcing.F, external_fields_load.F
1068     o Computation of surface tendencies before tendency updates.
1069       -> new: external_forcing_surf.F
1070     o Change of variable names useGMRedi, useKPP, useECCO
1071     o Further changes in dynamics.F, impldiff.F for TAMC
1072     o Tested for experiments 0, 2, 4.
1073       - not yet tested for GMRedi.
1074       - not yet tested for KPP.
1075    
1076    checkpoint30
1077     o Updates for OBCs
1078     o New experiment for test OBCs (internal_wave)
1079     o New output.txt in verification/exp4/results/
1080     o Updates for KPP: calculation of viscosity corrected, new variables
1081       kpp_dumpFreq and kpp_taveFreq
1082     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
1083       and entry for T90 in genmake
1084    
1085    checkpoint29
1086     o packaged KPP and GM/Redi
1087    
1088    checkpoint28
1089     o Corrected initialization of hFacMin for difference vertical coordinates
1090     o Modified calculation of partial cell thickness to more robust algorithm
1091     o config_summary.F: replaced write_1D_... by write_0D_...
1092       read_write.F: added subroutines write_0D_...
1093     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
1094       included some initialisations required for TAMC.
1095     o routine calc_isoslopes: modified sqrt computation to make it
1096       differentiable for zero argument.
1097     o routines dynamics, impldiff:
1098       included store directives and tape key computations required for TAMC.
1099     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
1100    
1101    checkpoint27
1102     o fixed calc_isoslopes() to so that cancellation of terms in tensor
1103       formulation works properly with variable resolution.
1104     o restructured the calling tree between the_model_main() and dynamics()
1105     o split initialise() into initialise_fixed() and initialise_varia()
1106     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
1107       in new routine ini_psurf()
1108    
1109    checkpoint26
1110     o moved some #ifdef in optional routines to encompass everything
1111       except the argument declarations. This was using up some memory.
1112     o fixed macros like _ADT to work with both versions of Linux cpp
1113     o cleaned up some unused and uninitialized variables
1114       (helps when debugging with strict compile options)
1115     o split up CPP_EEOPTIONS.h into options and macros
1116       (macros are now in eesupp/inc/CPP_EEMACROS.h)
1117     o patch for 2 processor JAM mode
1118    
1119    checkpoint25
1120     o updates for OBCs and NH
1121     o dramatically reduced memory usage

1124     o added a diagnostic of convective index
1125     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
1126       (this is was partly for OBCs and NH but also in anticipation of
1127        an explicit free-surface option)
1128     o initial state input files for U and V
1129    
1130    checkpoint24
1131     o Removed some spurious "REAL"s

1138    
1139    checkpoint22
1140     o Made many small changes: implicit none, format(i5), etc...
1141     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
1142    
1143    checkpoint21
1144     o Introduced new I/O package that supports direct-access records (mdsio.F)
1145     o Split-up mid-level I/O routines
1146     o Updated input data for experiments 0,1,2,4 and 5
1147     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
1148    
1149    checkpoint20
1150     o Tidied up open-boundaries some more
1151     o Added non-hydrostatic code
1152     o Fixed some input data

1176       accumulation in reverse mode. Adjoint of an
1177       assignment is an addition.
1178     o Changes to support compilation by TAMC (LR(1)
1179       syntax) and by g77 under Linux ( 72 character
1180       limit ).
1181    
1182    checkpoint15
1183     Rewrote exchange routines to allow
1184     o General tile <-> tile connectivity.

1194    
1195    checkpoint13
1196     Release which corrects global_max problem and a couple
1197     of KGM time-averaging diagnostic errors. Also contains
1198     a double-gyre experiment setup as well as the baseline
1199     4 degree global template. The double gyre template is
1200     organised to allow it to be applied automatically to
1201     the baseline configuration.
1202    
1203    branch-point-rdot
1204     A few tidy-ups have been made bt the real point of this
1205     check-point (excuse the pun) is to allow a branch to be
1206     made for the purposes of adding the rDot alterations.
1207     I don't want to commit the rDot to the main-trunk until
1208     we've actually tested it...
1209
