135    o Added on-the-fly spatial interpolation capability
136        "USE_EXF_INTERPOLATION" to pkg/exf.
137      - This is a temporary Cartesian-grid hack until
138        the super-duper ESMF coupler becomes available.
139      - See verification/global_with_exf/README for usage example.
140      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid

198    
199    checkpoint51
200    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
201      - autodiff, ctrl, exf, grdchk, seaice
202      kept separate packages
203      - cost, ecco, obcs
204    o updating verification/internal_wave, verification/lab_sea
205      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
206    
207    checkpoint50i_post
208    o Preparing next differentiable checkpoint and sync
209      of MAIN vs. ecco-branch
210      - 1st step: this one is differentiable
211      - 2nd step: next(! not this) checkpoint will have updated packages
212                  from ecco-branch)
213    
214    checkpoint50h_post
215    o new package "land": provide surface BC for AIM.
216    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
217    o AIM: use true log-P extrapolation for near surface temp (= as in
218        F.Molteni paper) ; update aim.5l_cs output.
219    o New variable in PARM03 for more flexible pickups
220    o somewhat cleaned package initialisation sequence for
221      ctrl/ cost/ ecco/ in packages_... routines
222    
223    checkpoint50g_post
224    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
225      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
226      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
227        made the default because of faster convergence than ADI
228    
229    checkpoint50f_post
230    o exf totally restructured
231      - replaced all exf_set_ routines by one generic exf_set_gen.F
232        and made sure it's still differentiable

245     o removed lots of single quotes from comments
246    
247    checkpoint50e_post
248    o make KPP work with PTRACERS
249     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
250       nearly a copy of kpp_transport_s
251     - there is no analogue to SurfaceTendencyS, so I have to use
252       gPtr(of the surface layer) instead
253    o add a new platform SunFire+mpi (SunFire 15000) to genmake
254    checkpoint50e_pre
255    
256    checkpoint50d_post
257    o change kpp output from multiple-record state files to single-record state
258      files analogous to write_state.F
259    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
260      analogous to the cg2d-related output.
261    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
262      so that writing to internal file fn (with length 512) fails.
263    checkpoint50d_pre
264    
265    checkpoint50c_post
266    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)

268    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
269    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
270    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
271    
272    checkpoint50c_pre
273    Merging from release1_p13:
274    o bug fix for pkg/seaice dynamic solver
275    o Added SEAICE_initialHEFF to pkg/seaice
276    
277    checkpoint50b_post
278    o store u*,v* in gU,V instead of in guNm1,gvNm1
279    o in order to put the momForcing out of the Adams-Bashforth:
280      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
281      to timestep.F
282    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
283    o re-generate output for highly sensitive test-exp:

288    o corrected CPP option mismatch in exf_Bulk... functions for case
289      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
290    
291    checkpoint50a_post
292    o Bug fix for merging between c50 and KPP.
293      ikey was passed from thermodynamics to kpp_calc via
294      common block rather than being recomputed in kpp_calc,
295      in contradiction with new key itdkey.
296      New key ikppkey created, and tamc.h headers updated.
297    
298    checkpoint50
299    - 2nd step of merge with ecco-branch:
300      merge changes in ecco-branch back into main trunk
301    - bug fix in find_alpha
302    - more storing in gmredi_calc_tensor.F, kpp_routines.F
303    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
304    - merged some sliced AD support routines
305    
306    checkpoint49
307    merged from ecco-branch:
308    o exf:
309      - Enable initialisation of forcing fields to constant
310        (runtime) values.
311      - in exf_getffields.F
312        Reduce i-/j-loop to interior domain, discarding overlaps.
313        That also fixes wrong TAF-key computations for key_1, key_2
314        with bulf formulae.
315      - exf_init.F modify #ifdef for exf_init_evap
316      - exf_getffieldrec.F, ctrl_getrec.F
317        The following INT-usages are not safe:
318          fldsecs  = int(fldsecs/fldperiod)*fldperiod
319          fldcount = int(fldsecs/fldperiod) + 1
320        and were modified.
321    o autodiff: checkpoint_lev...
322      - updated storing for bulk formulae (some arrays were missing)
323      - added state for seaice package
324      - synchronized with main branch
325    o DIVA:
326      Modif.s in
327      - the_main_loop.F
328      - the_model_main.F
329      and added cost_final_restore.F cost_final_store.F
330      o With these changes, it is possible to fully separate
331        the first forward run to compute the cost function (mdthe_main_loop)
332        and adjoint runs over individual DIVA intervals (adthe_main_loop)
333        into separate model executions.
334        This enables better tuning of DIVA to given queue sizes.
335      o Loss of cost function value in consecutive DIVA runs is
336        fixed by storing to 'costfinal' file.
337      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
338        beginning/end of adjoint integration is accounted for.
339      The current changes apply to TAF-1.4.26.
340      TAF has one remaining bug, requiring one manual change
341      (see MITgcm manual).
342    o cal: synchronized between MAIN and ecco-branch
343    
344    checkpoint48i_post
345    o Changes to restore differentiability of code w.r.t. previous tag
346      (mostly adding new routines to make list and replacing
347      pressure by totPhiHyd).
348    o Updated and merged grdchk package
349      - has both ADM and TLM checks
350      - works for single- and multi-proc.
351      - output cleaned
352      - worked successfully for parallel DIVA
353    o genmake:
354      - Adding -platform=SP4
355      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
356    o Modif. for DIVA:
357      ctrl_unpack should not be called in intermediate DIVA interval.
358      (similar thing would apply for active files such as
359      tbar, sbar, psbar, which should not be reinitialised;
360      only relevant for ecco-branch)
361    
362    checkpoint48h_post
363    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
364    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
365    o Added SEAICE_initialHEFF to pkg/seaice
366    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
367    
368    checkpoint48g_post
369    --- EOS:
370    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
371      store total Potential in totPhyHyd for diagnostics & EOS.
372    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
373    --- Pressure/geopotential gradient:
374    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
375    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
376      ( changes results of global_ocean_pressure )
377    o NLFS + z-coord.: add eta*Rho' contribution.
378    o accurate phiHyd when using interface-W at the middle between 2 centers
379     ( changes results of ideal_2D_oce )
380    o includes r* 2nd term in potential gradient.
381    
382    checkpoint48f_post
383    Merging from release1_p12:
384    o Modifications for using pkg/exf with pkg/seaice
385      - improved description of the various forcing configurations

390      (SBO) core products, including oceanic mass, center-of-mass,
391      angular, and bottom pressure (see pkg/sbo/README.sbo).
392    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
393      to avoid negative values in shallow regions.
394      - updated verification/natl_box/results/output.txt
395      - updated verification/lab_sea/results/output.txt
396    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
397    o Added useSingleCpuIO option (see PARAMS.h).
398    o Updated useSingleCpuIO option in mdsio_writefield.F to
399      work with multi-field files, e.g., for single-file pickup.
400    o pkg/seaice:
401      - bug fix in growth.F: QNET for no shortwave case
402      - added HeffFile for specifying initial sea-ice thickness
403      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
404    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
405      kpp_transport_t.F, forward_step.F, and the_main_loop.F
406    o pkg/seaice:
407      - adjoint-friendly modifications
408      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F

412    o dynamics: change definition of computational domain & adapt mom_fluxform
413      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
414    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
415        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
416        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
417        global_ocean.90x40x15 global_with_exf global_ocean_pressure

422    o in preparation for r*:
423     a) use pre-computed gradient of hydrostatic potential:
424        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
425     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
426        => affects results of glob_oce_pressure (different truncation error)  
427      update output.txt of ideal_2D_oce & global_ocean_pressure

430    o in preparation for r*:
431      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
432      pass the 2 comp. of the grad. as arguments to momentum S/R.
433      but for the moment, only used if it does not change the results.
434    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
