108    `
109    >>>checkpoint51b_post
110    adjoint of ptracers

127    o modify code for biogeo packages
128      - in model/src and pkg/ptracers
129    
130    checkpoint51
131    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
132      - autodiff, ctrl, exf, grdchk, seaice
133      kept separate packages
134      - cost, ecco, obcs
135    o updating verification/internal_wave, verification/lab_sea
136      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
137    
138    checkpoint50i_post
139    o Preparing next differentiable checkpoint and sync
140      of MAIN vs. ecco-branch
141      - 1st step: this one is differentiable
142      - 2nd step: next(! not this) checkpoint will have updated packages
143                  from ecco-branch)
144    
145    checkpoint50h_post
146    o new package "land": provide surface BC for AIM.
147    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
148    o AIM: use true log-P extrapolation for near surface temp (= as in
149        F.Molteni paper) ; update aim.5l_cs output.
150    o New variable in PARM03 for more flexible pickups
151    o somewhat cleaned package initialisation sequence for
152      ctrl/ cost/ ecco/ in packages_... routines
153    
154    checkpoint50g_post
155    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
156      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
157      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
158        made the default because of faster convergence than ADI
159    
160    checkpoint50f_post
161    o exf totally restructured
162      - replaced all exf_set_ routines by one generic exf_set_gen.F
163        and made sure it's still differentiable
164      - split exf_getffields.F into new exf_bulkformulae.F
165      - exf_inscal_/exf_outscal_ suffixes consistent with field names

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