5    
6    checkpoint51f_pre
7    o Added on-the-fly spatial interpolation capability
8        "USE_EXF_INTERPOLATION" to pkg/exf.
9      - This is a temporary Cartesian-grid hack until
10        the super-duper ESMF coupler becomes available.
11      - See verification/global_with_exf/README for usage example.
12      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
13        flags and modified pkg/seaice accordingly.
14    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
15        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
16        non-local transport term.
17

44      - debLevA: standard
45      - debLevB: equivalent to current debugMode=.TRUE.
46    o introducing pathname variable mdsioLocalDir for mdsio
47      that can be specified at runtime

68    o modify code for biogeo packages
69      - in model/src and pkg/ptracers
70    
71    checkpoint51
72    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
73      - autodiff, ctrl, exf, grdchk, seaice
74      kept separate packages
75      - cost, ecco, obcs
76    o updating verification/internal_wave, verification/lab_sea
77      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
78    
79    checkpoint50i_post
80    o Preparing next differentiable checkpoint and sync
81      of MAIN vs. ecco-branch
82      - 1st step: this one is differentiable
83      - 2nd step: next(! not this) checkpoint will have updated packages
84                  from ecco-branch)
85    
86    checkpoint50h_post
87    o new package "land": provide surface BC for AIM.
88    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
89    o AIM: use true log-P extrapolation for near surface temp (= as in
90        F.Molteni paper) ; update aim.5l_cs output.
91    o New variable in PARM03 for more flexible pickups
92    o somewhat cleaned package initialisation sequence for
93      ctrl/ cost/ ecco/ in packages_... routines
94    
95    checkpoint50g_post
96    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
97      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
98      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
99        made the default because of faster convergence than ADI
100    
101    checkpoint50f_post
102    o exf totally restructured
103      - replaced all exf_set_ routines by one generic exf_set_gen.F
104        and made sure it's still differentiable
105      - split exf_getffields.F into new exf_bulkformulae.F
106      - exf_inscal_/exf_outscal_ suffixes consistent with field names
107      - updated adjoint/makefile and relevant verif. accordingly
108    
109    checkpoint50f_pre
110     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
111          + change Evap over land. (update aim.5l_cs output)
112     o added missing .cvsignores and made uniform across expts
113     o changed configuration of tidal_basin_2d expt
114     o added pkg/debug functions for tracing code in fatal crashes
115     o tidied pkg/monitor to use MONITOR_OPTIONS.h
116     o new fn in pkg/monitor to stop model if solution grows too big
117     o removed lots of single quotes from comments
118    
119    checkpoint50e_post
120    o make KPP work with PTRACERS
121     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
122       nearly a copy of kpp_transport_s
123     - there is no analogue to SurfaceTendencyS, so I have to use
124       gPtr(of the surface layer) instead
125    o add a new platform SunFire+mpi (SunFire 15000) to genmake
126    checkpoint50e_pre
127    
128    checkpoint50d_post
129    o change kpp output from multiple-record state files to single-record state
130      files analogous to write_state.F
131    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
132      analogous to the cg2d-related output.
133    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
134      so that writing to internal file fn (with length 512) fails.
135    checkpoint50d_pre
136    
137    checkpoint50c_post
138    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
139    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
140    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
141    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
142    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
143    
144    checkpoint50c_pre
145    Merging from release1_p13:
146    o bug fix for pkg/seaice dynamic solver
147    o Added SEAICE_initialHEFF to pkg/seaice
148    
149    checkpoint50b_post
150    o store u*,v* in gU,V instead of in guNm1,gvNm1
151    o in order to put the momForcing out of the Adams-Bashforth:
152      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
153      to timestep.F
154    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
155    o re-generate output for highly sensitive test-exp:
156       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
157    
158    checkpoint50b_pre
159    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
160    o corrected CPP option mismatch in exf_Bulk... functions for case
161      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
162    
163    checkpoint50a_post
164    o Bug fix for merging between c50 and KPP.
165      ikey was passed from thermodynamics to kpp_calc via
166      common block rather than being recomputed in kpp_calc,
167      in contradiction with new key itdkey.
168      New key ikppkey created, and tamc.h headers updated.
169    
170    checkpoint50
171    - 2nd step of merge with ecco-branch:
172      merge changes in ecco-branch back into main trunk
173    - bug fix in find_alpha
174    - more storing in gmredi_calc_tensor.F, kpp_routines.F
175    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
176    - merged some sliced AD support routines
177    
178    checkpoint49
179    merged from ecco-branch:
180    o exf:
181      - Enable initialisation of forcing fields to constant
182        (runtime) values.
183      - in exf_getffields.F
184        Reduce i-/j-loop to interior domain, discarding overlaps.
185        That also fixes wrong TAF-key computations for key_1, key_2
186        with bulf formulae.
187      - exf_init.F modify #ifdef for exf_init_evap
188      - exf_getffieldrec.F, ctrl_getrec.F
189        The following INT-usages are not safe:
190          fldsecs  = int(fldsecs/fldperiod)*fldperiod
191          fldcount = int(fldsecs/fldperiod) + 1
192        and were modified.
193    o autodiff: checkpoint_lev...
194      - updated storing for bulk formulae (some arrays were missing)
195      - added state for seaice package
196      - synchronized with main branch
197    o DIVA:
198      Modif.s in
199      - the_main_loop.F
200      - the_model_main.F
201      and added cost_final_restore.F cost_final_store.F
202      o With these changes, it is possible to fully separate
203        the first forward run to compute the cost function (mdthe_main_loop)
204        and adjoint runs over individual DIVA intervals (adthe_main_loop)
205        into separate model executions.
206        This enables better tuning of DIVA to given queue sizes.
207      o Loss of cost function value in consecutive DIVA runs is
208        fixed by storing to 'costfinal' file.
209      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
210        beginning/end of adjoint integration is accounted for.
211      The current changes apply to TAF-1.4.26.
212      TAF has one remaining bug, requiring one manual change
213      (see MITgcm manual).
214    o cal: synchronized between MAIN and ecco-branch
215    
216    checkpoint48i_post
217    o Changes to restore differentiability of code w.r.t. previous tag
218      (mostly adding new routines to make list and replacing
219      pressure by totPhiHyd).
220    o Updated and merged grdchk package
221      - has both ADM and TLM checks
222      - works for single- and multi-proc.
223      - output cleaned
224      - worked successfully for parallel DIVA
225    o genmake:
226      - Adding -platform=SP4
227      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
228    o Modif. for DIVA:
229      ctrl_unpack should not be called in intermediate DIVA interval.
230      (similar thing would apply for active files such as
231      tbar, sbar, psbar, which should not be reinitialised;
232      only relevant for ecco-branch)
233    
234    checkpoint48h_post
235    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
236    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
237    o Added SEAICE_initialHEFF to pkg/seaice
238    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
239    
240    checkpoint48g_post
241    --- EOS:
242    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
243      store total Potential in totPhyHyd for diagnostics & EOS.
244    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
245    --- Pressure/geopotential gradient:
246    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
247    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
248      ( changes results of global_ocean_pressure )
249    o NLFS + z-coord.: add eta*Rho' contribution.
250    o accurate phiHyd when using interface-W at the middle between 2 centers
251     ( changes results of ideal_2D_oce )
252    o includes r* 2nd term in potential gradient.
253    
254    checkpoint48f_post
255    Merging from release1_p12:
256    o Modifications for using pkg/exf with pkg/seaice
257      - improved description of the various forcing configurations
258      - added basic radiation bulk formulae to pkg/exf
259      - units/sign fix for evap computation in exf_getffields.F
260      - updated verification/global_with_exf/results/output.txt
261    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
262      (SBO) core products, including oceanic mass, center-of-mass,
263      angular, and bottom pressure (see pkg/sbo/README.sbo).
264    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
265      to avoid negative values in shallow regions.
266      - updated verification/natl_box/results/output.txt
267      - updated verification/lab_sea/results/output.txt
268    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
269    o Added useSingleCpuIO option (see PARAMS.h).
270    o Updated useSingleCpuIO option in mdsio_writefield.F to
271      work with multi-field files, e.g., for single-file pickup.
272    o pkg/seaice:
273      - bug fix in growth.F: QNET for no shortwave case
274      - added HeffFile for specifying initial sea-ice thickness
275      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
276    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
277      kpp_transport_t.F, forward_step.F, and the_main_loop.F
278    o pkg/seaice:
279      - adjoint-friendly modifications
280      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
281    
282    checkpoint48e_post
283    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
284    o dynamics: change definition of computational domain & adapt mom_fluxform
285      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
286    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
287        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
288        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
289        global_ocean.90x40x15 global_with_exf global_ocean_pressure
290        inverted_barometer solid-body.cs-32x32x1
291      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
292    
293    checkpoint48d_post
294    o in preparation for r*:
295     a) use pre-computed gradient of hydrostatic potential:
296        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
297     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
298        => affects results of glob_oce_pressure (different truncation error)  
299      update output.txt of ideal_2D_oce & global_ocean_pressure
300    
301    checkpoint48d_pre
302    o in preparation for r*:
303      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
304      pass the 2 comp. of the grad. as arguments to momentum S/R.
305      but for the moment, only used if it does not change the results.
306    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
307    
308    checkpoint48c_post
309    Modifications in treatment of initial flux forcing controls
310    to avoid extra storing of flux fields.
311    
312    checkpoint48c_pre
313    o Added tidal_basin_2d experiment (currently 1D!)
314    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
315    
316    checkpoint48b_post
317    o r* coordinate added in #ifdef NONLIN_FRSURF block.
318     (modification to pressure gradient not yet implemented)
319    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
320      (for U & V) that are used for vertical advection of momentum.
321    
322    checkpoint48a_post
323    o In preparation for r*, use temp. array to compute vertical transport
324       in flux-form momentum pkg. => change results of few test-exp.
325      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
326                        lab_sea, natl_box & plume_on_slope
327    
328    checkpoint48
329    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
330    
331    checkpoint47j_post
332    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
333    o moved adexch from forward_step to addummy_in_stepping
334    o added exch in ctrl_map_...
335    o aveFreq.=0. at end of cost_final to avoid overwrite in
336      reverse checkpointing loop
337    o Yet more changes in gmredi:
338      * adgmredi_calc_tensor
339        avoiding all recomputation of gmredi_slope_limit
340      * adgmredi_x/y/rtransport
341        added flag for excessive storing to avoid recomp. of
342        u/v/rtans, dTdx/y/z
343        -> this is not really necessary and very memory-consuming
344      * adgmredi_slope_psi:
345        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
346      * gmredi_slope_limit
347        re-activated full calculation of taperfct for case 'ac02'
348    o updating verification/ adjoints of carbon, global_ocean.90x40x15
349    
350    checkpoint47i_post
351    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
352    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
353      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
354    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
355    o gmredi: fix few bugs.
356    
357    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
358    This will be a good checkpoint to plug into the ecco-branch.
359    o few modif.'s to get latest version adjointed
360      (mainly kick out code in ini_linear_phisurf)
361    o modif's to run adjoint with exactConserv
362    o case GM_BOLUS_ADVEC should be cleaned
363      S/R gmredi_slope_psi should be cleaned
364    o verification/carbon now has exactConserv=.TRUE.
365    
366    checkpoint47g_post
367    o time-average AIM output: becomes independent from statvars time-average
368      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
369    o After TAF bug fix:
370      Tested adjoint of gmredi package.
371      Tests were done with checkpoint47 rather than with latest
372      checkpoint47f_post since the latter is broken for the adjoint
373      verification/carbon/ contains both ADM and TLM gradient checks.
374    Here they are, before they get changed/lost/stolen.
375    Mostly modif.'s to fix numerical sensitivities.
376    Gradient checks OK for
377    - GM_taper_scheme:
378      * clipping
379      * ac02
380      * linear
381      * glw91
382      * dm95
383      * ldd97
384    - GMREDI_OPTIONS:
385      * GM_VISBECK_VARIABLE_K
386      * GM_NON_UNITY_DIAGONAL
387      * GM_EXTRA_DIAGONAL
388      * GM_BOLUS_ADVEC
389    in conjunction with data.gmredi parameters to be checked in
390    in a few minutes under verification/carbon/code/
391    
392    checkpoint47f_post
393    Merging from release1_p10:
394    o modifications for using pkg/exf with pkg/seaice
395      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
396        and SEAICE_EXTERNAL_FLUXES
397      - pkg/exf CPP options EXF_READ_EVAP and
398        EXF_NO_BULK_COMPUTATIONS
399      - usage examples are Experiments 8 and 9 in
400        verification/lab_sea/README
401      - verification/lab_sea default experiment now uses
402        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
403    
404    checkpoint47e_post
405    o created a tag prior to creating a branch
406    
407    checkpoint47d_post
408    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
409      at the bottom boundary had an erroneous half slip boundary condition
410    o added bottom drag and no slip boundary condition capabilities to
411      oceanic pressure coordinates code
412    o added new verification experiment global_ocean_pressure, this experiment is
413      also described in the tutorial section of the manual
414    checkpoint47d_pre
415    
416    checkpoint47c_post
417    o Added a verification experiment for a global cubed-sphere ocean run
418      -  verification/global_ocean.cubed32x32x30
419      -  uses pkg/therm_seaice and pkg/bulk_forcing
420    
421    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
422    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
423      when using P-coordinate; only implemented for atmospheric config.
424    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
425      NOTES: requires option NONLIN_FRSURF to be "#define".
426    o update advect_xz/results/output.txt (left from checkpoint44g_post)

430    o pkg/seaice
431      - removed GOTO's and added taf directives
432      - double precision constants to reduce the g77 (Linux)
433        to F77 (SGI) differences reported in release1_p8
434    o tools/genmake
435      - added SGI options
436    o verification/testscript
437      - updated to that of checkpoint47a_post
