116    o modify code for biogeo packages
117      - in model/src and pkg/ptracers
118    
119    checkpoint51
120    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
121      - autodiff, ctrl, exf, grdchk, seaice
122      kept separate packages
123      - cost, ecco, obcs
124    o updating verification/internal_wave, verification/lab_sea
125      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
126    
127    checkpoint50i_post
128    o Preparing next differentiable checkpoint and sync
129      of MAIN vs. ecco-branch
130      - 1st step: this one is differentiable
131      - 2nd step: next(! not this) checkpoint will have updated packages
132                  from ecco-branch)
133    
134    checkpoint50h_post
135    o new package "land": provide surface BC for AIM.
136    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
137    o AIM: use true log-P extrapolation for near surface temp (= as in
138        F.Molteni paper) ; update aim.5l_cs output.
139    o New variable in PARM03 for more flexible pickups
140    o somewhat cleaned package initialisation sequence for
141      ctrl/ cost/ ecco/ in packages_... routines
142    
143    checkpoint50g_post
144    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
145      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
146      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
147        made the default because of faster convergence than ADI
148    
149    checkpoint50f_post
150    o exf totally restructured
151      - replaced all exf_set_ routines by one generic exf_set_gen.F
152        and made sure it's still differentiable
153      - split exf_getffields.F into new exf_bulkformulae.F
154      - exf_inscal_/exf_outscal_ suffixes consistent with field names
155      - updated adjoint/makefile and relevant verif. accordingly
156    
157    checkpoint50f_pre

164     o new fn in pkg/monitor to stop model if solution grows too big
165     o removed lots of single quotes from comments
166    
167    checkpoint50e_post
168    o make KPP work with PTRACERS
169     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
170       nearly a copy of kpp_transport_s
171     - there is no analogue to SurfaceTendencyS, so I have to use
172       gPtr(of the surface layer) instead
173    o add a new platform SunFire+mpi (SunFire 15000) to genmake
174    checkpoint50e_pre
175    
176    checkpoint50d_post
177    o change kpp output from multiple-record state files to single-record state
178      files analogous to write_state.F
179    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
180      analogous to the cg2d-related output.
181    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
182      so that writing to internal file fn (with length 512) fails.
183    checkpoint50d_pre
184    
185    checkpoint50c_post
186    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
187    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
188    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
189    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
190    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
191    
192    checkpoint50c_pre
193    Merging from release1_p13:
194    o bug fix for pkg/seaice dynamic solver
195    o Added SEAICE_initialHEFF to pkg/seaice
196    
197    checkpoint50b_post
198    o store u*,v* in gU,V instead of in guNm1,gvNm1
199    o in order to put the momForcing out of the Adams-Bashforth:
200      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
201      to timestep.F
202    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
203    o re-generate output for highly sensitive test-exp:
204       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
205    
206    checkpoint50b_pre
207    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
208    o corrected CPP option mismatch in exf_Bulk... functions for case
209      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
210    
211    checkpoint50a_post
212    o Bug fix for merging between c50 and KPP.
213      ikey was passed from thermodynamics to kpp_calc via
214      common block rather than being recomputed in kpp_calc,
215      in contradiction with new key itdkey.
216      New key ikppkey created, and tamc.h headers updated.
217    
218    checkpoint50
219    - 2nd step of merge with ecco-branch:
220      merge changes in ecco-branch back into main trunk
221    - bug fix in find_alpha
222    - more storing in gmredi_calc_tensor.F, kpp_routines.F
223    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
224    - merged some sliced AD support routines
225    
226    checkpoint49
227    merged from ecco-branch:
228    o exf:
229      - Enable initialisation of forcing fields to constant
230        (runtime) values.
231      - in exf_getffields.F
232        Reduce i-/j-loop to interior domain, discarding overlaps.
233        That also fixes wrong TAF-key computations for key_1, key_2
234        with bulf formulae.
235      - exf_init.F modify #ifdef for exf_init_evap
236      - exf_getffieldrec.F, ctrl_getrec.F
237        The following INT-usages are not safe:
238          fldsecs  = int(fldsecs/fldperiod)*fldperiod
239          fldcount = int(fldsecs/fldperiod) + 1
240        and were modified.
241    o autodiff: checkpoint_lev...
242      - updated storing for bulk formulae (some arrays were missing)
243      - added state for seaice package
244      - synchronized with main branch
245    o DIVA:
246      Modif.s in
247      - the_main_loop.F
248      - the_model_main.F
249      and added cost_final_restore.F cost_final_store.F
250      o With these changes, it is possible to fully separate
251        the first forward run to compute the cost function (mdthe_main_loop)
252        and adjoint runs over individual DIVA intervals (adthe_main_loop)
253        into separate model executions.
254        This enables better tuning of DIVA to given queue sizes.
255      o Loss of cost function value in consecutive DIVA runs is
256        fixed by storing to 'costfinal' file.
257      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
258        beginning/end of adjoint integration is accounted for.
259      The current changes apply to TAF-1.4.26.
260      TAF has one remaining bug, requiring one manual change
261      (see MITgcm manual).
262    o cal: synchronized between MAIN and ecco-branch
263    
264    checkpoint48i_post
265    o Changes to restore differentiability of code w.r.t. previous tag
266      (mostly adding new routines to make list and replacing
267      pressure by totPhiHyd).
268    o Updated and merged grdchk package
269      - has both ADM and TLM checks
270      - works for single- and multi-proc.
271      - output cleaned
272      - worked successfully for parallel DIVA
273    o genmake:
274      - Adding -platform=SP4
275      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
276    o Modif. for DIVA:
277      ctrl_unpack should not be called in intermediate DIVA interval.
278      (similar thing would apply for active files such as
279      tbar, sbar, psbar, which should not be reinitialised;
280      only relevant for ecco-branch)
281    
282    checkpoint48h_post
283    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
284    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
285    o Added SEAICE_initialHEFF to pkg/seaice
286    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
287    
288    checkpoint48g_post
289    --- EOS:
290    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
291      store total Potential in totPhyHyd for diagnostics & EOS.
292    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
293    --- Pressure/geopotential gradient:
294    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
295    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
296      ( changes results of global_ocean_pressure )
297    o NLFS + z-coord.: add eta*Rho' contribution.
298    o accurate phiHyd when using interface-W at the middle between 2 centers
299     ( changes results of ideal_2D_oce )
300    o includes r* 2nd term in potential gradient.
301    
302    checkpoint48f_post
303    Merging from release1_p12:
304    o Modifications for using pkg/exf with pkg/seaice
305      - improved description of the various forcing configurations
306      - added basic radiation bulk formulae to pkg/exf
307      - units/sign fix for evap computation in exf_getffields.F
308      - updated verification/global_with_exf/results/output.txt
309    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
310      (SBO) core products, including oceanic mass, center-of-mass,
311      angular, and bottom pressure (see pkg/sbo/README.sbo).
312    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
313      to avoid negative values in shallow regions.
314      - updated verification/natl_box/results/output.txt
315      - updated verification/lab_sea/results/output.txt
316    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
317    o Added useSingleCpuIO option (see PARAMS.h).
318    o Updated useSingleCpuIO option in mdsio_writefield.F to
319      work with multi-field files, e.g., for single-file pickup.
320    o pkg/seaice:
321      - bug fix in growth.F: QNET for no shortwave case
322      - added HeffFile for specifying initial sea-ice thickness
323      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
324    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
325      kpp_transport_t.F, forward_step.F, and the_main_loop.F
326    o pkg/seaice:
327      - adjoint-friendly modifications
328      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
329    
330    checkpoint48e_post
331    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
332    o dynamics: change definition of computational domain & adapt mom_fluxform
333      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
334    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
335        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
336        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
337        global_ocean.90x40x15 global_with_exf global_ocean_pressure
338        inverted_barometer solid-body.cs-32x32x1
339      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
340    
341    checkpoint48d_post
342    o in preparation for r*:
343     a) use pre-computed gradient of hydrostatic potential:
344        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
345     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
346        => affects results of glob_oce_pressure (different truncation error)  
347      update output.txt of ideal_2D_oce & global_ocean_pressure
348    
349    checkpoint48d_pre
350    o in preparation for r*:
351      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
352      pass the 2 comp. of the grad. as arguments to momentum S/R.
353      but for the moment, only used if it does not change the results.
354    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
355    
356    checkpoint48c_post
357    Modifications in treatment of initial flux forcing controls
358    to avoid extra storing of flux fields.
359    
360    checkpoint48c_pre
361    o Added tidal_basin_2d experiment (currently 1D!)
362    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
363    
364    checkpoint48b_post
365    o r* coordinate added in #ifdef NONLIN_FRSURF block.
366     (modification to pressure gradient not yet implemented)
367    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
368      (for U & V) that are used for vertical advection of momentum.
369    
370    checkpoint48a_post
371    o In preparation for r*, use temp. array to compute vertical transport
372       in flux-form momentum pkg. => change results of few test-exp.
373      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
374                        lab_sea, natl_box & plume_on_slope
375    
376    checkpoint48
377    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
378    
379    checkpoint47j_post
380    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
381    o moved adexch from forward_step to addummy_in_stepping
382    o added exch in ctrl_map_...
383    o aveFreq.=0. at end of cost_final to avoid overwrite in
384      reverse checkpointing loop
385    o Yet more changes in gmredi:
386      * adgmredi_calc_tensor
387        avoiding all recomputation of gmredi_slope_limit
388      * adgmredi_x/y/rtransport
389        added flag for excessive storing to avoid recomp. of
390        u/v/rtans, dTdx/y/z
391        -> this is not really necessary and very memory-consuming
392      * adgmredi_slope_psi:
393        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
394      * gmredi_slope_limit
395        re-activated full calculation of taperfct for case 'ac02'
396    o updating verification/ adjoints of carbon, global_ocean.90x40x15
397    
398    checkpoint47i_post
399    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
400    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
401      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
402    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
403    o gmredi: fix few bugs.
404    
405    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
406    This will be a good checkpoint to plug into the ecco-branch.
407    o few modif.'s to get latest version adjointed
408      (mainly kick out code in ini_linear_phisurf)
409    o modif's to run adjoint with exactConserv
410    o case GM_BOLUS_ADVEC should be cleaned
411      S/R gmredi_slope_psi should be cleaned
412    o verification/carbon now has exactConserv=.TRUE.
413    
414    checkpoint47g_post
415    o time-average AIM output: becomes independent from statvars time-average
416      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
417    o After TAF bug fix:
418      Tested adjoint of gmredi package.
419      Tests were done with checkpoint47 rather than with latest
420      checkpoint47f_post since the latter is broken for the adjoint
421      verification/carbon/ contains both ADM and TLM gradient checks.
422    Here they are, before they get changed/lost/stolen.
423    Mostly modif.'s to fix numerical sensitivities.
424    Gradient checks OK for
425    - GM_taper_scheme:
426      * clipping
427      * ac02
428      * linear
429      * glw91
430      * dm95
431      * ldd97
432    - GMREDI_OPTIONS:
433      * GM_VISBECK_VARIABLE_K
434      * GM_NON_UNITY_DIAGONAL
435      * GM_EXTRA_DIAGONAL
436      * GM_BOLUS_ADVEC
437    in conjunction with data.gmredi parameters to be checked in
438    in a few minutes under verification/carbon/code/
439    
440    checkpoint47f_post
441    Merging from release1_p10:
442    o modifications for using pkg/exf with pkg/seaice
443      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
444        and SEAICE_EXTERNAL_FLUXES
445      - pkg/exf CPP options EXF_READ_EVAP and
446        EXF_NO_BULK_COMPUTATIONS
447      - usage examples are Experiments 8 and 9 in
448        verification/lab_sea/README
449      - verification/lab_sea default experiment now uses
450        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
451    
452    checkpoint47e_post
453    o created a tag prior to creating a branch
454    
455    checkpoint47d_post
456    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
457      at the bottom boundary had an erroneous half slip boundary condition
458    o added bottom drag and no slip boundary condition capabilities to
459      oceanic pressure coordinates code
460    o added new verification experiment global_ocean_pressure, this experiment is
461      also described in the tutorial section of the manual
462    checkpoint47d_pre

464    checkpoint47c_post
465    o Added a verification experiment for a global cubed-sphere ocean run
466      -  verification/global_ocean.cubed32x32x30
467      -  uses pkg/therm_seaice and pkg/bulk_forcing
468    
469    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
470    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
471      when using P-coordinate; only implemented for atmospheric config.
472    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
473      NOTES: requires option NONLIN_FRSURF to be "#define".
474    o update advect_xz/results/output.txt (left from checkpoint44g_post)
