99    o modify code for biogeo packages
100      - in model/src and pkg/ptracers
101    
102    checkpoint51
103    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
104      - autodiff, ctrl, exf, grdchk, seaice
105      kept separate packages
106      - cost, ecco, obcs
107    o updating verification/internal_wave, verification/lab_sea
108      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
109    
110    checkpoint50i_post
111    o Preparing next differentiable checkpoint and sync
112      of MAIN vs. ecco-branch
113      - 1st step: this one is differentiable
114      - 2nd step: next(! not this) checkpoint will have updated packages
115                  from ecco-branch)
116    
117    checkpoint50h_post
118    o new package "land": provide surface BC for AIM.
119    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
120    o AIM: use true log-P extrapolation for near surface temp (= as in
121        F.Molteni paper) ; update aim.5l_cs output.
122    o New variable in PARM03 for more flexible pickups
123    o somewhat cleaned package initialisation sequence for
124      ctrl/ cost/ ecco/ in packages_... routines
125    
126    checkpoint50g_post
127    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
128      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
129      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
130        made the default because of faster convergence than ADI
131    
132    checkpoint50f_post
133    o exf totally restructured
134      - replaced all exf_set_ routines by one generic exf_set_gen.F
135        and made sure it's still differentiable
136      - split exf_getffields.F into new exf_bulkformulae.F
137      - exf_inscal_/exf_outscal_ suffixes consistent with field names
138      - updated adjoint/makefile and relevant verif. accordingly
139    
140    checkpoint50f_pre
141     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
142          + change Evap over land. (update aim.5l_cs output)
143     o added missing .cvsignores and made uniform across expts
144     o changed configuration of tidal_basin_2d expt
145     o added pkg/debug functions for tracing code in fatal crashes

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

464        to F77 (SGI) differences reported in release1_p8
465    o tools/genmake
466      - added SGI options
467    o verification/testscript
468      - updated to that of checkpoint47a_post
469    o verification/global_ocean.90x40x15/input/eedata
