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

194    
195    checkpoint51
196    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
197      - autodiff, ctrl, exf, grdchk, seaice
198      kept separate packages
199      - cost, ecco, obcs
200    o updating verification/internal_wave, verification/lab_sea
201      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
202    
203    checkpoint50i_post
204    o Preparing next differentiable checkpoint and sync
205      of MAIN vs. ecco-branch
206      - 1st step: this one is differentiable
207      - 2nd step: next(! not this) checkpoint will have updated packages
208                  from ecco-branch)
209    
210    checkpoint50h_post
211    o new package "land": provide surface BC for AIM.
212    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
213    o AIM: use true log-P extrapolation for near surface temp (= as in
214        F.Molteni paper) ; update aim.5l_cs output.
215    o New variable in PARM03 for more flexible pickups
216    o somewhat cleaned package initialisation sequence for
217      ctrl/ cost/ ecco/ in packages_... routines
218    
219    checkpoint50g_post
220    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
221      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
222      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
223        made the default because of faster convergence than ADI
224    
225    checkpoint50f_post
226    o exf totally restructured
227      - replaced all exf_set_ routines by one generic exf_set_gen.F
228        and made sure it's still differentiable
229      - split exf_getffields.F into new exf_bulkformulae.F

241     o removed lots of single quotes from comments
242    
243    checkpoint50e_post
244    o make KPP work with PTRACERS
245     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
246       nearly a copy of kpp_transport_s
247     - there is no analogue to SurfaceTendencyS, so I have to use
248       gPtr(of the surface layer) instead
249    o add a new platform SunFire+mpi (SunFire 15000) to genmake
250    checkpoint50e_pre
251    
252    checkpoint50d_post
253    o change kpp output from multiple-record state files to single-record state
254      files analogous to write_state.F
255    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
256      analogous to the cg2d-related output.
257    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
258      so that writing to internal file fn (with length 512) fails.
259    checkpoint50d_pre
260    
261    checkpoint50c_post
262    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)

264    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
265    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
266    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
267    
268    checkpoint50c_pre
269    Merging from release1_p13:
270    o bug fix for pkg/seaice dynamic solver
271    o Added SEAICE_initialHEFF to pkg/seaice
272    
273    checkpoint50b_post
274    o store u*,v* in gU,V instead of in guNm1,gvNm1
275    o in order to put the momForcing out of the Adams-Bashforth:
276      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
277      to timestep.F
278    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
279    o re-generate output for highly sensitive test-exp:
280       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
281    
282    checkpoint50b_pre
283    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
284    o corrected CPP option mismatch in exf_Bulk... functions for case
285      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
286    
287    checkpoint50a_post
288    o Bug fix for merging between c50 and KPP.
289      ikey was passed from thermodynamics to kpp_calc via
290      common block rather than being recomputed in kpp_calc,
291      in contradiction with new key itdkey.
292      New key ikppkey created, and tamc.h headers updated.
293    
294    checkpoint50
295    - 2nd step of merge with ecco-branch:
296      merge changes in ecco-branch back into main trunk
297    - bug fix in find_alpha
298    - more storing in gmredi_calc_tensor.F, kpp_routines.F
299    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
300    - merged some sliced AD support routines
301    
302    checkpoint49
303    merged from ecco-branch:
304    o exf:
305      - Enable initialisation of forcing fields to constant
306        (runtime) values.
307      - in exf_getffields.F
308        Reduce i-/j-loop to interior domain, discarding overlaps.
309        That also fixes wrong TAF-key computations for key_1, key_2
310        with bulf formulae.
311      - exf_init.F modify #ifdef for exf_init_evap
312      - exf_getffieldrec.F, ctrl_getrec.F
313        The following INT-usages are not safe:
314          fldsecs  = int(fldsecs/fldperiod)*fldperiod
315          fldcount = int(fldsecs/fldperiod) + 1
316        and were modified.
317    o autodiff: checkpoint_lev...
318      - updated storing for bulk formulae (some arrays were missing)
319      - added state for seaice package
320      - synchronized with main branch
321    o DIVA:
322      Modif.s in
323      - the_main_loop.F
324      - the_model_main.F
325      and added cost_final_restore.F cost_final_store.F
326      o With these changes, it is possible to fully separate
327        the first forward run to compute the cost function (mdthe_main_loop)
328        and adjoint runs over individual DIVA intervals (adthe_main_loop)
329        into separate model executions.
330        This enables better tuning of DIVA to given queue sizes.
331      o Loss of cost function value in consecutive DIVA runs is
332        fixed by storing to 'costfinal' file.
333      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
334        beginning/end of adjoint integration is accounted for.
335      The current changes apply to TAF-1.4.26.
336      TAF has one remaining bug, requiring one manual change
337      (see MITgcm manual).
338    o cal: synchronized between MAIN and ecco-branch
339    
340    checkpoint48i_post
341    o Changes to restore differentiability of code w.r.t. previous tag
342      (mostly adding new routines to make list and replacing
343      pressure by totPhiHyd).
344    o Updated and merged grdchk package
345      - has both ADM and TLM checks
346      - works for single- and multi-proc.
347      - output cleaned
348      - worked successfully for parallel DIVA
349    o genmake:
350      - Adding -platform=SP4
351      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
352    o Modif. for DIVA:
353      ctrl_unpack should not be called in intermediate DIVA interval.
354      (similar thing would apply for active files such as
355      tbar, sbar, psbar, which should not be reinitialised;
356      only relevant for ecco-branch)
357    
358    checkpoint48h_post
359    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
360    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
361    o Added SEAICE_initialHEFF to pkg/seaice
362    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
363    
364    checkpoint48g_post
365    --- EOS:
366    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
367      store total Potential in totPhyHyd for diagnostics & EOS.
368    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
369    --- Pressure/geopotential gradient:
370    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
371    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
372      ( changes results of global_ocean_pressure )
373    o NLFS + z-coord.: add eta*Rho' contribution.
374    o accurate phiHyd when using interface-W at the middle between 2 centers
375     ( changes results of ideal_2D_oce )
376    o includes r* 2nd term in potential gradient.
377    
378    checkpoint48f_post
379    Merging from release1_p12:
380    o Modifications for using pkg/exf with pkg/seaice

383      - units/sign fix for evap computation in exf_getffields.F
384      - updated verification/global_with_exf/results/output.txt
385    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
386      (SBO) core products, including oceanic mass, center-of-mass,
387      angular, and bottom pressure (see pkg/sbo/README.sbo).
388    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
389      to avoid negative values in shallow regions.
390      - updated verification/natl_box/results/output.txt
391      - updated verification/lab_sea/results/output.txt
392    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
393    o Added useSingleCpuIO option (see PARAMS.h).
394    o Updated useSingleCpuIO option in mdsio_writefield.F to
395      work with multi-field files, e.g., for single-file pickup.
396    o pkg/seaice:
397      - bug fix in growth.F: QNET for no shortwave case
398      - added HeffFile for specifying initial sea-ice thickness
399      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
400    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
401      kpp_transport_t.F, forward_step.F, and the_main_loop.F

407    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
408    o dynamics: change definition of computational domain & adapt mom_fluxform
409      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
410    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
411        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
412        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
413        global_ocean.90x40x15 global_with_exf global_ocean_pressure
414        inverted_barometer solid-body.cs-32x32x1
415      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
416    
417    checkpoint48d_post
418    o in preparation for r*:
419     a) use pre-computed gradient of hydrostatic potential:
420        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
421     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
422        => affects results of glob_oce_pressure (different truncation error)  
423      update output.txt of ideal_2D_oce & global_ocean_pressure

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