85    o Added on-the-fly spatial interpolation capability
86        "USE_EXF_INTERPOLATION" to pkg/exf.
87      - This is a temporary Cartesian-grid hack until
88        the super-duper ESMF coupler becomes available.
89      - See verification/global_with_exf/README for usage example.
90      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid

123      - debLevB: equivalent to current debugMode=.TRUE.
124    o introducing pathname variable mdsioLocalDir for mdsio

126      (relevant for cluster I/O to local disk)
127    `
128    >>>checkpoint51b_post
129    adjoint of ptracers
130    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM

144      - new pkgs: dic, gchem
145      - new subroutine in ptracers
146    o modify code for biogeo packages
147      - in model/src and pkg/ptracers
148    
149    checkpoint51
150    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
151      - autodiff, ctrl, exf, grdchk, seaice
152      kept separate packages
153      - cost, ecco, obcs
154    o updating verification/internal_wave, verification/lab_sea
155      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
156    
157    checkpoint50i_post
158    o Preparing next differentiable checkpoint and sync
159      of MAIN vs. ecco-branch
160      - 1st step: this one is differentiable
161      - 2nd step: next(! not this) checkpoint will have updated packages
162                  from ecco-branch)
163    
164    checkpoint50h_post
165    o new package "land": provide surface BC for AIM.
166    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
167    o AIM: use true log-P extrapolation for near surface temp (= as in
168        F.Molteni paper) ; update aim.5l_cs output.
169    o New variable in PARM03 for more flexible pickups
170    o somewhat cleaned package initialisation sequence for
171      ctrl/ cost/ ecco/ in packages_... routines
172    
173    checkpoint50g_post
174    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
175      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
176      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
177        made the default because of faster convergence than ADI
178    
179    checkpoint50f_post
180    o exf totally restructured
181      - replaced all exf_set_ routines by one generic exf_set_gen.F
182        and made sure it's still differentiable
183      - split exf_getffields.F into new exf_bulkformulae.F

195     o removed lots of single quotes from comments
196    
197    checkpoint50e_post
198    o make KPP work with PTRACERS
199     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
200       nearly a copy of kpp_transport_s
201     - there is no analogue to SurfaceTendencyS, so I have to use
202       gPtr(of the surface layer) instead
203    o add a new platform SunFire+mpi (SunFire 15000) to genmake
204    checkpoint50e_pre
205    
206    checkpoint50d_post
207    o change kpp output from multiple-record state files to single-record state
208      files analogous to write_state.F
209    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
210      analogous to the cg2d-related output.
211    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
212      so that writing to internal file fn (with length 512) fails.
213    checkpoint50d_pre
214    
215    checkpoint50c_post
216    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
217    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
218    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
219    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
220    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
221    
222    checkpoint50c_pre
223    Merging from release1_p13:
224    o bug fix for pkg/seaice dynamic solver
225    o Added SEAICE_initialHEFF to pkg/seaice
226    
227    checkpoint50b_post
228    o store u*,v* in gU,V instead of in guNm1,gvNm1
229    o in order to put the momForcing out of the Adams-Bashforth:
230      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
231      to timestep.F
232    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
233    o re-generate output for highly sensitive test-exp:
234       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
235    
236    checkpoint50b_pre
237    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
238    o corrected CPP option mismatch in exf_Bulk... functions for case
239      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
240    
241    checkpoint50a_post
242    o Bug fix for merging between c50 and KPP.
243      ikey was passed from thermodynamics to kpp_calc via
244      common block rather than being recomputed in kpp_calc,
245      in contradiction with new key itdkey.
246      New key ikppkey created, and tamc.h headers updated.
247    
248    checkpoint50
249    - 2nd step of merge with ecco-branch:
250      merge changes in ecco-branch back into main trunk
251    - bug fix in find_alpha
252    - more storing in gmredi_calc_tensor.F, kpp_routines.F
253    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
254    - merged some sliced AD support routines
255    
256  checkpoint49  checkpoint49
257    merged from ecco-branch:
258    o exf:
259      - Enable initialisation of forcing fields to constant
260        (runtime) values.
261      - in exf_getffields.F
262        Reduce i-/j-loop to interior domain, discarding overlaps.
263        That also fixes wrong TAF-key computations for key_1, key_2
264        with bulf formulae.
265      - exf_init.F modify #ifdef for exf_init_evap
266      - exf_getffieldrec.F, ctrl_getrec.F
267        The following INT-usages are not safe:
268          fldsecs  = int(fldsecs/fldperiod)*fldperiod
269          fldcount = int(fldsecs/fldperiod) + 1
270        and were modified.
271    o autodiff: checkpoint_lev...
272      - updated storing for bulk formulae (some arrays were missing)
273      - added state for seaice package
274      - synchronized with main branch
275    o DIVA:
276      Modif.s in
277      - the_main_loop.F
278      - the_model_main.F
279      and added cost_final_restore.F cost_final_store.F
280      o With these changes, it is possible to fully separate
281        the first forward run to compute the cost function (mdthe_main_loop)
282        and adjoint runs over individual DIVA intervals (adthe_main_loop)
283        into separate model executions.
284        This enables better tuning of DIVA to given queue sizes.
285      o Loss of cost function value in consecutive DIVA runs is
286        fixed by storing to 'costfinal' file.
287      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
288        beginning/end of adjoint integration is accounted for.
289      The current changes apply to TAF-1.4.26.
290      TAF has one remaining bug, requiring one manual change
291      (see MITgcm manual).
292    o cal: synchronized between MAIN and ecco-branch
293    
294    checkpoint48i_post
295  o Changes to restore differentiability of code w.r.t. previous tag  o Changes to restore differentiability of code w.r.t. previous tag
296    (mostly adding new routines to make list and replacing    (mostly adding new routines to make list and replacing
297    pressure by totPhiHyd).    pressure by totPhiHyd).
