57      - in model/src and pkg/ptracers
58    
59    checkpoint51
60    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
61      - autodiff, ctrl, exf, grdchk, seaice
62      kept separate packages
63      - cost, ecco, obcs
64    o updating verification/internal_wave, verification/lab_sea
65      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
66    
67    checkpoint50i_post
68    o Preparing next differentiable checkpoint and sync
69      of MAIN vs. ecco-branch
70      - 1st step: this one is differentiable
71      - 2nd step: next(! not this) checkpoint will have updated packages
72                  from ecco-branch)
73    
74    checkpoint50h_post
75    o new package "land": provide surface BC for AIM.
76    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
77    o AIM: use true log-P extrapolation for near surface temp (= as in
78        F.Molteni paper) ; update aim.5l_cs output.
79    o New variable in PARM03 for more flexible pickups
80    o somewhat cleaned package initialisation sequence for
81      ctrl/ cost/ ecco/ in packages_... routines
82    
83    checkpoint50g_post
84    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
85      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
86      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
87        made the default because of faster convergence than ADI
88    
89    checkpoint50f_post
90    o exf totally restructured
91      - replaced all exf_set_ routines by one generic exf_set_gen.F
92        and made sure it's still differentiable
93      - split exf_getffields.F into new exf_bulkformulae.F
94      - exf_inscal_/exf_outscal_ suffixes consistent with field names
95      - updated adjoint/makefile and relevant verif. accordingly
96    
97    checkpoint50f_pre
98     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
99          + change Evap over land. (update aim.5l_cs output)
100     o added missing .cvsignores and made uniform across expts
101     o changed configuration of tidal_basin_2d expt
102     o added pkg/debug functions for tracing code in fatal crashes
103     o tidied pkg/monitor to use MONITOR_OPTIONS.h
104     o new fn in pkg/monitor to stop model if solution grows too big
105     o removed lots of single quotes from comments
106    
107    checkpoint50e_post
108    o make KPP work with PTRACERS
109     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
110       nearly a copy of kpp_transport_s
111     - there is no analogue to SurfaceTendencyS, so I have to use
112       gPtr(of the surface layer) instead
113    o add a new platform SunFire+mpi (SunFire 15000) to genmake
114    checkpoint50e_pre
115    
116    checkpoint50d_post
117    o change kpp output from multiple-record state files to single-record state
118      files analogous to write_state.F
119    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
120      analogous to the cg2d-related output.
121    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
122      so that writing to internal file fn (with length 512) fails.
123    checkpoint50d_pre
124    
125    checkpoint50c_post
126    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
127    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
128    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
129    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
130    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
131    
132    checkpoint50c_pre
133    Merging from release1_p13:
134    o bug fix for pkg/seaice dynamic solver
135    o Added SEAICE_initialHEFF to pkg/seaice
136    
137    checkpoint50b_post
138    o store u*,v* in gU,V instead of in guNm1,gvNm1
139    o in order to put the momForcing out of the Adams-Bashforth:
140      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
141      to timestep.F
142    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
143    o re-generate output for highly sensitive test-exp:
144       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
145    
146    checkpoint50b_pre
147    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
148    o corrected CPP option mismatch in exf_Bulk... functions for case
149      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
150    
151    checkpoint50a_post
152    o Bug fix for merging between c50 and KPP.
153      ikey was passed from thermodynamics to kpp_calc via
154      common block rather than being recomputed in kpp_calc,
155      in contradiction with new key itdkey.
156      New key ikppkey created, and tamc.h headers updated.
157    
158    checkpoint50
159    - 2nd step of merge with ecco-branch:
160      merge changes in ecco-branch back into main trunk
161    - bug fix in find_alpha
162    - more storing in gmredi_calc_tensor.F, kpp_routines.F
163    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
164    - merged some sliced AD support routines
165    
166    checkpoint49
167    merged from ecco-branch:
168    o exf:
169      - Enable initialisation of forcing fields to constant
170        (runtime) values.
171      - in exf_getffields.F
172        Reduce i-/j-loop to interior domain, discarding overlaps.
173        That also fixes wrong TAF-key computations for key_1, key_2
174        with bulf formulae.
175      - exf_init.F modify #ifdef for exf_init_evap
176      - exf_getffieldrec.F, ctrl_getrec.F
177        The following INT-usages are not safe:
178          fldsecs  = int(fldsecs/fldperiod)*fldperiod
179          fldcount = int(fldsecs/fldperiod) + 1
180        and were modified.
181    o autodiff: checkpoint_lev...
182      - updated storing for bulk formulae (some arrays were missing)
183      - added state for seaice package
184      - synchronized with main branch
185    o DIVA:
186      Modif.s in
187      - the_main_loop.F
188      - the_model_main.F
189      and added cost_final_restore.F cost_final_store.F
190      o With these changes, it is possible to fully separate
191        the first forward run to compute the cost function (mdthe_main_loop)
192        and adjoint runs over individual DIVA intervals (adthe_main_loop)
193        into separate model executions.
194        This enables better tuning of DIVA to given queue sizes.
195      o Loss of cost function value in consecutive DIVA runs is
196        fixed by storing to 'costfinal' file.
197      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
198        beginning/end of adjoint integration is accounted for.
199      The current changes apply to TAF-1.4.26.
200      TAF has one remaining bug, requiring one manual change
201      (see MITgcm manual).
202    o cal: synchronized between MAIN and ecco-branch
203    
204    checkpoint48i_post
205    o Changes to restore differentiability of code w.r.t. previous tag
206      (mostly adding new routines to make list and replacing
207      pressure by totPhiHyd).
208    o Updated and merged grdchk package
209      - has both ADM and TLM checks
210      - works for single- and multi-proc.
211      - output cleaned
212      - worked successfully for parallel DIVA
213    o genmake:
214      - Adding -platform=SP4
215      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
216    o Modif. for DIVA:
217      ctrl_unpack should not be called in intermediate DIVA interval.
218      (similar thing would apply for active files such as
219      tbar, sbar, psbar, which should not be reinitialised;
220      only relevant for ecco-branch)
221    
222    checkpoint48h_post
223    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
224    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
225    o Added SEAICE_initialHEFF to pkg/seaice
226    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
227    
228    checkpoint48g_post
229    --- EOS:
230    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
231      store total Potential in totPhyHyd for diagnostics & EOS.
232    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
233    --- Pressure/geopotential gradient:
234    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
235    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
236      ( changes results of global_ocean_pressure )
237    o NLFS + z-coord.: add eta*Rho' contribution.
238    o accurate phiHyd when using interface-W at the middle between 2 centers
239     ( changes results of ideal_2D_oce )
240    o includes r* 2nd term in potential gradient.
241    
242    checkpoint48f_post
243    Merging from release1_p12:
244    o Modifications for using pkg/exf with pkg/seaice
245      - improved description of the various forcing configurations
246      - added basic radiation bulk formulae to pkg/exf
247      - units/sign fix for evap computation in exf_getffields.F
248      - updated verification/global_with_exf/results/output.txt
249    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
250      (SBO) core products, including oceanic mass, center-of-mass,
251      angular, and bottom pressure (see pkg/sbo/README.sbo).
252    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
253      to avoid negative values in shallow regions.
254      - updated verification/natl_box/results/output.txt
255      - updated verification/lab_sea/results/output.txt
256    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
257    o Added useSingleCpuIO option (see PARAMS.h).
258    o Updated useSingleCpuIO option in mdsio_writefield.F to
259      work with multi-field files, e.g., for single-file pickup.
260    o pkg/seaice:
261      - bug fix in growth.F: QNET for no shortwave case
262      - added HeffFile for specifying initial sea-ice thickness
263      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
264    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
265      kpp_transport_t.F, forward_step.F, and the_main_loop.F
266    o pkg/seaice:
267      - adjoint-friendly modifications
268      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
269    
270    checkpoint48e_post
271    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
272    o dynamics: change definition of computational domain & adapt mom_fluxform
273      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
274    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
275        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
276        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
277        global_ocean.90x40x15 global_with_exf global_ocean_pressure
278        inverted_barometer solid-body.cs-32x32x1
279      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
280    
281    checkpoint48d_post
282    o in preparation for r*:
283     a) use pre-computed gradient of hydrostatic potential:
284        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
285     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
286        => affects results of glob_oce_pressure (different truncation error)  
287      update output.txt of ideal_2D_oce & global_ocean_pressure
288    
289    checkpoint48d_pre
290    o in preparation for r*:
291      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
292      pass the 2 comp. of the grad. as arguments to momentum S/R.
293      but for the moment, only used if it does not change the results.
294    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
295    
296    checkpoint48c_post
297    Modifications in treatment of initial flux forcing controls
298    to avoid extra storing of flux fields.
299    
300    checkpoint48c_pre
301    o Added tidal_basin_2d experiment (currently 1D!)
302    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
303    
304    checkpoint48b_post
305    o r* coordinate added in #ifdef NONLIN_FRSURF block.
306     (modification to pressure gradient not yet implemented)
307    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
308      (for U & V) that are used for vertical advection of momentum.
309    
310    checkpoint48a_post
311    o In preparation for r*, use temp. array to compute vertical transport
312       in flux-form momentum pkg. => change results of few test-exp.
313      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
314                        lab_sea, natl_box & plume_on_slope
315    
316    checkpoint48
317    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
318    
319    checkpoint47j_post
320    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
321    o moved adexch from forward_step to addummy_in_stepping
322    o added exch in ctrl_map_...
323    o aveFreq.=0. at end of cost_final to avoid overwrite in
324      reverse checkpointing loop
325    o Yet more changes in gmredi:
326      * adgmredi_calc_tensor
327        avoiding all recomputation of gmredi_slope_limit
328      * adgmredi_x/y/rtransport
329        added flag for excessive storing to avoid recomp. of
330        u/v/rtans, dTdx/y/z
331        -> this is not really necessary and very memory-consuming
332      * adgmredi_slope_psi:
333        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
334      * gmredi_slope_limit
335        re-activated full calculation of taperfct for case 'ac02'
336    o updating verification/ adjoints of carbon, global_ocean.90x40x15
337    
338    checkpoint47i_post
339    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
340    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
341      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
342    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
343    o gmredi: fix few bugs.
344    
345    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
346    This will be a good checkpoint to plug into the ecco-branch.
347    o few modif.'s to get latest version adjointed
348      (mainly kick out code in ini_linear_phisurf)
349    o modif's to run adjoint with exactConserv
350    o case GM_BOLUS_ADVEC should be cleaned
351      S/R gmredi_slope_psi should be cleaned
352    o verification/carbon now has exactConserv=.TRUE.
353    
354    checkpoint47g_post
355    o time-average AIM output: becomes independent from statvars time-average
356      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
357    o After TAF bug fix:
358      Tested adjoint of gmredi package.
359      Tests were done with checkpoint47 rather than with latest
360      checkpoint47f_post since the latter is broken for the adjoint
361      verification/carbon/ contains both ADM and TLM gradient checks.
362    Here they are, before they get changed/lost/stolen.
363    Mostly modif.'s to fix numerical sensitivities.
364    Gradient checks OK for
365    - GM_taper_scheme:
366      * clipping
367      * ac02
368      * linear
369      * glw91
370      * dm95
371      * ldd97
372    - GMREDI_OPTIONS:
373      * GM_VISBECK_VARIABLE_K
374      * GM_NON_UNITY_DIAGONAL
375      * GM_EXTRA_DIAGONAL
376      * GM_BOLUS_ADVEC
377    in conjunction with data.gmredi parameters to be checked in
378    in a few minutes under verification/carbon/code/
379    
380    checkpoint47f_post
381    Merging from release1_p10:
382    o modifications for using pkg/exf with pkg/seaice
383      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
384        and SEAICE_EXTERNAL_FLUXES
385      - pkg/exf CPP options EXF_READ_EVAP and
386        EXF_NO_BULK_COMPUTATIONS
387      - usage examples are Experiments 8 and 9 in
388        verification/lab_sea/README
389      - verification/lab_sea default experiment now uses
390        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
391    
392    checkpoint47e_post
393    o created a tag prior to creating a branch
394    
395    checkpoint47d_post
396    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
397      at the bottom boundary had an erroneous half slip boundary condition
398    o added bottom drag and no slip boundary condition capabilities to
399      oceanic pressure coordinates code
400    o added new verification experiment global_ocean_pressure, this experiment is
401      also described in the tutorial section of the manual
402    checkpoint47d_pre
403    
404    checkpoint47c_post
405    o Added a verification experiment for a global cubed-sphere ocean run
406      -  verification/global_ocean.cubed32x32x30
407      -  uses pkg/therm_seaice and pkg/bulk_forcing
408    
409    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
410    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
411      when using P-coordinate; only implemented for atmospheric config.
412    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
413      NOTES: requires option NONLIN_FRSURF to be "#define".
414    o update advect_xz/results/output.txt (left from checkpoint44g_post)
415    
416    checkpoint47b_post
417    Merging from release1_p9:
