4      ==============================      ==============================
5    
6    o changes to calc_gw.F
7     - bug fix for w^2 term near the bottom boundary
8     - (hopefully) improve the lateral slip boundary condtions for use with
9        partial/looped cells
10      - because the bug fix changes two verification experiments anyway (exp5
11        and plume on slope), change the lateral boundary condition from half slip
12        to the value of no_slip_sides
13    o ebm package wasnt quite up to the parallel task. Fixed that.
14    
15    checkpoint53b_post
16    o Commiting new energy balance model to repository
17      * package is pkg/ebm
18      * verif. is verification/global_ocean_ebm
19      * references are in ebm_driver.F
20    C      * X. Wang, P. Stone and J. Marotzke, 1999:
21    C        Global thermohaline circulation. Part I:
22    C        Sensitivity to atmospheric moisture transport.
23    C        J. Climate 12(1), 71-82
24    C      * X. Wang, P. Stone and J. Marotzke, 1999:
25    C        Global thermohaline circulation. Part II:
26    C        Sensitivity with interactive transport.
27    C        J. Climate 12(1), 83-91
28    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
29    C        Destabilization of the thermohaline circulation
30    C        by atmospheric eddy transports.
31    C        J. Climate 7(12), 1870-1882
32    o Will need long integration testing.
33    checkpoint53b_pre
34    
35    o created pkg/mom_common in preparation for variable viscosity code
36    o renamed and split ini_mnc_io
37    o pkg/land: only liquid water can diffuse or run-off
38    o AIM using land: soil wetness availability account for snow
39    o added printMapIncludesZeros to EEPARMS namelist
40    
41    checkpoint53a_post
42    o restore TAMC compatiility for exf_constants.h
43      (no usage of _d in .h)
44    o Additional storing in KPP in an attempt to fix
45      TAMC problem with adjoint of KPP code.
46      (no success...)
47      Identical code works fine with TAF.
48    o Fixed verification/natl_box_adjoint experiments.
49      Initial conditions for Experiments 4 and 5 are now
50      set to "SEAICE_initialHEFF=0", which is more reasonable,
51      and hence gives results closer to that of Experiment 2.
52      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
53    
54    checkpoint53
55    o stable checkpoint with up to date adjoint
56      TLM tests only run for 1st grdchk at the moment. Its unclear if
57      this is a code problem or a problem with resetting code for g_
58      variables that is being autogenerated wrong.
59      Otherwise:
60       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
61       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
62         are both still in chaos following their security messes.
63    
64    checkpoint52n_post
65    o various build (mostly genmake2) changes including:
66      - ability to build/run more easily within Cygwin and MacOS X
67      - more complicated Makefiles with a stronger dependence on Gnu Make
68    o pkg/seaice modifications
69      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
70        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
71        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
72      - changed proxy for geostrophic velocity and updated
73        verification/lab_sea/results/* accordingly
74      - removed ADI dynamic solver from pkg/seaice
75      - replaced all occurrences of 1/CSTICE or 1/CSUICE
76        they caused a segmentation fault under certain circumstances
77      - removed unused field WATR
78    o bug fix in exf-package:
79      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
80         now reflect that.
81    o small fixes in the cal-package:
82      - set reference date to first of January for the 'model'-calendar
83      - failing of cal_CheckDate in cal_FullDate now actually results in a
84        warning
85    o small modifications in exf-package to increase flexibility:
86      - change climtempfreeze from a constant to a runtime parameter that
87        is specified in data.exf_clim (default = -1.9)
88      - introduce runtime parameter windstressmax (default = 2.0) that is
89        specified in data.exf
90    o fix in pkg/thsice:
91      - update Evap (Tsf changes) to be consistent with Latent heat flux
92      - maintain snow precipitation unchanged (even if Tsf >=0).
93     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
94    
95    checkpoint52m_post
96    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
97      this does not change any of the results, because myIter=0 in swfrac always
98      lead to jwtype=2 (the default anyway), but the call makes little sense
99      as a default
100    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
101    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
102      atmospheric model (AIM) to use it ; add a "slab ocean" component.
103    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
104    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
105    o extending useSingleCpuIO option to work with new exch2 I/O format
106      - old-style, missing-tile I/O is still accessible by defining CPP
107        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
108    o monitor package can write to NetCDF files and/or STDOUT
109    o fix re-definition bug in MNC_GRID_INIT_ALL()
110    o doc/api_reference added
111      - a framework for building an API Reference Manual using all
112        the "protex" comments embedded in the code
113      - see pkg/generic_advdiff, pkg/mnc for examples
114    o MNC:
115      - make myThid the last argument for all subroutines
116      - new default for the grid files: NO halos
117      - add useMNC and other run-time flags
118      - separate per-file-group handling of the unlimited dimension
119      - early initialization of MNC w/ flags read at the eeboot stage
120        and lookup tables set in initialize_fixed
121      - write all MNC output to a freshly-created directory
122    o thermodynamics sea-ice (thsice) is now tested with testreport.
123    o test exp. advect_cs: use the standard cs32 grid ; update output.
124    o Added functionality to grdchk:
125      pick global i,j,k position (or nearest wet) where to perform check.
126    
127    checkpoint52l_post
128    o new land formulation:
129      a) use ground enthalpy as prognostic variable to ensure exact
130         energy conservation.
131      b) account for water temperature and for latent heat of freezing
132         in all processes (rain, run-off, ground storage)
133      c) compute surface and ground temperature implicitly.
134    o aim_v23 modification for new land model:
135      a) Treat separately land / ocean / sea-ice surface fluxes
136         to allow implicit computation of land & sea-ice surface temp.
137      b) add snow precipitation.
138    checkpoint52l_pre
139    
140    o fix problem (when 1 tile is empty) in min/max monitor.
141    o fix bug in timeAve (u,vZetatave in common block)
142    o no restoring terms under ice for pkg/seaice
143    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
144    o bug fix for pkg/seaice pickups
145    o change MNC call locations and add coordinate attributes
146    o mask vorticity at the corner ; affects global_ocean.cs output
147    o fix ini_curvilinear_grid ; test CS experiments with mpi
148    o aim.5l_cs: modify sea-ice fraction input file ; update output
149    o exf: Adding simple range check routine for exf fields after read
150    
151    checkpoint52k_post
152    o removed top-level directory "diags"
153      - we migrated these functions to pkg/timeave a long time ago
154    o fixed bug introduced in pkg/monitor
155    o accuracy ctrlprec = 32 insuffient for gradient checks using
156      averaged fields (I/O via cost_averages)
157      -> use ctrl.h in active_file*.F to control I/O precision.
158    o paramter list of CALL ADTHE_MAIN_LOOP
159    o added initial do_the_model_io to ecco
160    o set all ...Freq to zero after cost_final
161      taveFreq, dumpFreq, pChkptFreq
162    o MAIN and ECCO differentiability restored
163    
164    checkpoint52j_post
165    o fix nchklev in tamc.h for global_ocean...
166    o Bringing flow and store directives up-to-date
167    o Really weird thing!
168      call do_the_model_io from the_main_loop with parameters
169      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
170      TAF places a faulty re-call of initialise_varia
171      after cost_final call which should not be there!
172    checkpoint52j_pre
173    
174    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
175      error messages
176    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
177    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
178      debug output
179    o modfied mdsio_writefield.F to handle non-global files under exch2
180    o update AIM Cubed-Sphere exp (aim.5l_cs):
181      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
182    o update AIM Equatorial Channel exp:
183      use standard aim_v23 pkg and change the SST fields to be more realistic.
184    o globalFile now works with exch2
185    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
186      mon_vort3.F to make exch2 friendly with >1 tile per cube face
187    o limit timeave output for hi-res integrations
188    
189    checkpoint52i_post
190    o removed CPP_EEOPTIONS.h from verification/*/code
191    o updated the tiling for global_ocean_pressure
192    checkpoint52i_pre
193    
194    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
195      the old pkg/aim).
196    
197    checkpoint52h_pre
198    o shortened offending lines in exch2_send_rx?.template
199    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
200    o genmake2: add build & execute test for NetCDF code
201    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
202      old grid files, moved CPP_EEMACROS.h to pkg/exch2
203    o added useSingleCPUIO flag to monitor.F and mon_out.F
204    o added temporary hack for sea-ice dynamics on the cube:
205      metric terms are ignored and it is assumed that
206      there is no sea-ice on cube faces 1, 2, 4, and 5.
207    
208    checkpoint52f_post
209    o added exch2 cube routines to pkg/exch2
210    o modified hs94.cs-32x32x5 to use it
211    o added new grid files to hs94.cs-32x32x5
212    checkpoint52f_pre
213    
214    checkpoint52e_post
215    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
216      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
217    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
218      to work with implicit vertical advection and AB ;
219    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
220    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
221     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
222    checkpoint52e_pre
223    
224    o fix bug in impldiff when Nr=1 or Nr=2.
225    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
226    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
227    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
228      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
229    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
230    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
231    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
232    
233    checkpoint52d_post
234    o re-tiled many expts to allow comparison in multi-processor mode
235      - updated output accordingly
236      - changed hs94.128x64x5 to use intial T from file rather than use the
237        random number generator
238    o add infrastructure in model routines for fizhi and gridalt packages
239    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
240    o changes to permit hi-res, cubed-sphere, configuration
241      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
242      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
243      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
244        of surface winds for the cube
245      (A verification experiment, based on global_ocean.cs32x15, but with
246       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
247       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
248       complete with example surface forcing files and matlab scripts to look
249       at the output and compare it with that of global_ocean.cs32x15.)
250    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
251       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
252       to conform to the common rule.
253    o check-in the first version of the coupler + interfaces for multi-components
254       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
255       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
256       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
257       - ocean and atmos. share the same horizontal grid (no interpolation).
258       - exchanges between component and coupler is done in forward_step
259    o new verification experiment, cpl_aim+ocn:
260       coupled ocean - AIM atmosphere on cs32 grid.
261    
262    checkpoint52d_pre
263    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
264    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
265    
266    checkpoint52c_post
267    o Fixing OPTIONS files for use of exf:
268      - ALLOW_ECCO not needed
269      - ECCO_CPPOPTIONS.h should not be included from
270        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
271        as has been the case in the past
272      - All cal/exf related options are currently set in
273        single header file. Should remain so until we
274        agree on a consistent new policy.
275    o Removed all CPP options for cal package.
276      cal has no more CPP options.
277    o modified STOREs in GAD_ADVECTION
278    o corrected key comp. for passkey
279    
280    checkpoint52b_post
281    o new version: "thsice" of thermodynamic sea-ice pkg:
282     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
283     - modify fluxes but do not change theta directly;
284     - light cleaning of bulk_force pkg (still needed with thsice).
285     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
286       + output_thsice.txt to test thsice & bulk_force pkgs.
287    o put back grid & coriolis monitor output.
288    checkpoint52b_pre
289    
290    o call "do_the_model_io" at the beginning (=> dump initial state)
291    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
292    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
293      (need info on NUMBER_OF_PTRACERS)
294    o missing PTRACERS headers in some routines
295    o default tamc.h in pkg/autodiff supposed to crash
296      to ensure proper customization
297    
298    checkpoint52a_post
299    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
300      - moved surfaceTendencyTice from pkg/seaice to main code
301      - subroutine FREEZE_SURFACE now limits only surface temperature
302        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
303        => new output.txt for global_ocean.cs32x15 & global_with_exf
304      - keep the old version of FREEZE for backward compatibility;
305        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
306      - corresponding modifs for TAF directives
307    o added surface flux output variables to TIMEAVE_STATVARS
308    o time-averaged output for pkg/ptracers
309    o fix problem with ECCO-related divided adjoint
310      snapshot file was missing some ad-variables,
311      but no warning issued by TAF
312    
313    checkpoint52a_pre
314    o some bug fixes for #undef REAL4_IS_SLOW
315    
316    checkpoint52 = ecco_c52_e35
317    o after testing adjoints of checkpoint51u_post
318    
319    checkpoint51u_post
320    o this is the post-merge tag of the ecco-branch
321      (needs another clean checkout and re-testing)
322    o various natl_box_adjoint configs and results
323      but no input fields
324    o obcs adjoint not yet merged!
325    o adding ECCO global 1x1 and 2x2 degree configs
326    o updated/extended some store directives for seaice
327    o pkg/ecco now containes ecco-specific part of cost function
328    o top level routines the_main_loop, forward_step
329      supersede those in model/src/
330      previous input data.cost now in data.ecco
331      (new namelist ecco_cost_nml)
332    o in ctrl/ cleaned some cross-dependencies and updated CPP options
333    
334    checkpoint51t_post
335    o this is the pre-merge tag of the ecco-branch
336    
337    checkpoint51s_post
338    o cleanup: removed various obsolete #define-s
339    o pkg/grdchk
340      - renamed 'ph-grd 3' to 'grad-res'
341      - merged from ecco-branch
342        (remaining bug fixes for obcs gradient checks)
343      - additional high-precision output for testreport
344        (grep for 'precision_grdchk_result')
345    
346    checkpoint51r_post
347    o cleaned up or removed CPP_OPTIONS.h files
348    o updated results for some of the tests to reflect the new
349      optfiles (-ieee: -O0 instead of -O3)
350    
351    checkpoint51q_post
352    o cd_code:
353      - moved cd_scheme.F -> cd_code_scheme.F
354      - separate read_checkpoint from cd_code_ini_vars.F
355      - separated cd_code part from write_checkpoint
356      - updated AD_SOURCE, generated .flow
357      - added CD_CODE_VARS.h to the_main_loop
358      - Moving cd_code specific store dir.s to pkg/cd_code
359    o ctrl package totally restructured
360      - pack/unpack now optional and decoupled from
361        xx_/adxx_ I/O
362      - ctrl_pack/unpack cleaned
363        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
364      - confined inclusion of AD_CONFIG.h to where necessary.
365    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
366    
367    checkpoint51p_post
368    o create initial cd_code package
369      - WARNING: the initialization of fields within packages
370        is broken because INI_FIELDS (where READ_CHECKPOINT is
371        called) is called *before* PACKAGES_INIT_VARIABLES.
372        This seems to be backwards since
373        1) its important to initially zero the entire field including
374           the "halo" region
375        2) zeroing needs to be done *before* reading pickup info
376           and the pickup call might or might not happen in any
377           particular run
378      - this needs an overhaul for R2
379    o cleanup verification/*/code/GMREDI_OPTIONS.h
380    o cleanup testreport
381    
382    checkpoint51o_post
383    o bringing AD-related verif's up to date with genmake2
384      - carbon/
385      - global_ocean.90x40x15/
386      - hs.94.1x64x5/
387      - (front_relax/ )
388    o (more) consistent directory structure for AD-related verif.'s
389    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
390    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
391    o bug fix in find_alpha.F for MDJWF:
392      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
393        change rho -> rho-rhoConst
394      - replace call find_rho to find_rhonum
395    o initialisation of rFlx extended to full array (required by TAF)
396      and shifted to thermodynamics
397    o removed PTRACERS.h in ptracers routine
398    o added surfacetendencyPtr to S/R parameter list pracers_forcing
399    o Correcting initialisations for fVerU, fVerV.
400    o helping TAF to recognize dependency on kUp for
401      fVerU, fVerV
402    o Replacing delZ by delR in pkg/ctrl/
403    checkpoint51o_pre

507    o Added on-the-fly spatial interpolation capability
508        "USE_EXF_INTERPOLATION" to pkg/exf.
509      - This is a temporary Cartesian-grid hack until
510        the super-duper ESMF coupler becomes available.
511      - See verification/global_with_exf/README for usage example.
512      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid

542    o introducing integer flag debugLevel
543      - debLevZero: suppress all output
544      - debLevA: standard
545      - debLevB: equivalent to current debugMode=.TRUE.
546    o introducing pathname variable mdsioLocalDir for mdsio
547      that can be specified at runtime
548      (relevant for cluster I/O to local disk)
549    `
550    >>>checkpoint51b_post
551    adjoint of ptracers

568    o modify code for biogeo packages
569      - in model/src and pkg/ptracers
570    
571    checkpoint51
572    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
573      - autodiff, ctrl, exf, grdchk, seaice
574      kept separate packages
575      - cost, ecco, obcs
576    o updating verification/internal_wave, verification/lab_sea
577      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
578    
579    checkpoint50i_post
580    o Preparing next differentiable checkpoint and sync
581      of MAIN vs. ecco-branch
582      - 1st step: this one is differentiable
583      - 2nd step: next(! not this) checkpoint will have updated packages
584                  from ecco-branch)
585    
586    checkpoint50h_post
587    o new package "land": provide surface BC for AIM.
588    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
589    o AIM: use true log-P extrapolation for near surface temp (= as in
590        F.Molteni paper) ; update aim.5l_cs output.
591    o New variable in PARM03 for more flexible pickups
592    o somewhat cleaned package initialisation sequence for
593      ctrl/ cost/ ecco/ in packages_... routines
594    
595    checkpoint50g_post
596    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
597      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
598      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
599        made the default because of faster convergence than ADI
600    
601    checkpoint50f_post
602    o exf totally restructured
603      - replaced all exf_set_ routines by one generic exf_set_gen.F
604        and made sure it's still differentiable
605      - split exf_getffields.F into new exf_bulkformulae.F

617     o removed lots of single quotes from comments
618    
619    checkpoint50e_post
620    o make KPP work with PTRACERS
621     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
622       nearly a copy of kpp_transport_s
623     - there is no analogue to SurfaceTendencyS, so I have to use
624       gPtr(of the surface layer) instead
625    o add a new platform SunFire+mpi (SunFire 15000) to genmake
626    checkpoint50e_pre
627    
628    checkpoint50d_post
629    o change kpp output from multiple-record state files to single-record state
630      files analogous to write_state.F
631    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
632      analogous to the cg2d-related output.
633    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
634      so that writing to internal file fn (with length 512) fails.
635    checkpoint50d_pre
636    
637    checkpoint50c_post
638    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)

640    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
641    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
642    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
643    
644    checkpoint50c_pre
645    Merging from release1_p13:
646    o bug fix for pkg/seaice dynamic solver
647    o Added SEAICE_initialHEFF to pkg/seaice
648    
649    checkpoint50b_post
650    o store u*,v* in gU,V instead of in guNm1,gvNm1
651    o in order to put the momForcing out of the Adams-Bashforth:
652      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
653      to timestep.F
654    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
655    o re-generate output for highly sensitive test-exp:
656       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
657    
658    checkpoint50b_pre
659    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
660    o corrected CPP option mismatch in exf_Bulk... functions for case
661      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
662    
663    checkpoint50a_post
664    o Bug fix for merging between c50 and KPP.
665      ikey was passed from thermodynamics to kpp_calc via
666      common block rather than being recomputed in kpp_calc,
667      in contradiction with new key itdkey.
668      New key ikppkey created, and tamc.h headers updated.
669    
670    checkpoint50
671    - 2nd step of merge with ecco-branch:
672      merge changes in ecco-branch back into main trunk
673    - bug fix in find_alpha
674    - more storing in gmredi_calc_tensor.F, kpp_routines.F
675    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
676    - merged some sliced AD support routines
677    
678    checkpoint49
679    merged from ecco-branch:
680    o exf:
681      - Enable initialisation of forcing fields to constant
682        (runtime) values.
683      - in exf_getffields.F
684        Reduce i-/j-loop to interior domain, discarding overlaps.
685        That also fixes wrong TAF-key computations for key_1, key_2
686        with bulf formulae.
687      - exf_init.F modify #ifdef for exf_init_evap
688      - exf_getffieldrec.F, ctrl_getrec.F
689        The following INT-usages are not safe:
690          fldsecs  = int(fldsecs/fldperiod)*fldperiod
691          fldcount = int(fldsecs/fldperiod) + 1
692        and were modified.
693    o autodiff: checkpoint_lev...
694      - updated storing for bulk formulae (some arrays were missing)
695      - added state for seaice package
696      - synchronized with main branch
697    o DIVA:
698      Modif.s in
699      - the_main_loop.F
700      - the_model_main.F
701      and added cost_final_restore.F cost_final_store.F
702      o With these changes, it is possible to fully separate
703        the first forward run to compute the cost function (mdthe_main_loop)
704        and adjoint runs over individual DIVA intervals (adthe_main_loop)
705        into separate model executions.
706        This enables better tuning of DIVA to given queue sizes.
707      o Loss of cost function value in consecutive DIVA runs is
708        fixed by storing to 'costfinal' file.
709      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
710        beginning/end of adjoint integration is accounted for.
711      The current changes apply to TAF-1.4.26.
712      TAF has one remaining bug, requiring one manual change
713      (see MITgcm manual).
714    o cal: synchronized between MAIN and ecco-branch
715    
716    checkpoint48i_post
717    o Changes to restore differentiability of code w.r.t. previous tag
718      (mostly adding new routines to make list and replacing
719      pressure by totPhiHyd).
720    o Updated and merged grdchk package
721      - has both ADM and TLM checks
722      - works for single- and multi-proc.
723      - output cleaned
724      - worked successfully for parallel DIVA
725    o genmake:
726      - Adding -platform=SP4
727      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
728    o Modif. for DIVA:
729      ctrl_unpack should not be called in intermediate DIVA interval.
730      (similar thing would apply for active files such as
731      tbar, sbar, psbar, which should not be reinitialised;
732      only relevant for ecco-branch)
733    
734    checkpoint48h_post
735    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
736    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
737    o Added SEAICE_initialHEFF to pkg/seaice
738    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
739    
740    checkpoint48g_post
741    --- EOS:
742    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
743      store total Potential in totPhyHyd for diagnostics & EOS.
744    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
745    --- Pressure/geopotential gradient:
746    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
747    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
748      ( changes results of global_ocean_pressure )
749    o NLFS + z-coord.: add eta*Rho' contribution.
750    o accurate phiHyd when using interface-W at the middle between 2 centers
751     ( changes results of ideal_2D_oce )
752    o includes r* 2nd term in potential gradient.
753    
754    checkpoint48f_post
755    Merging from release1_p12:

762      (SBO) core products, including oceanic mass, center-of-mass,
763      angular, and bottom pressure (see pkg/sbo/README.sbo).
764    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
765      to avoid negative values in shallow regions.
766      - updated verification/natl_box/results/output.txt
767      - updated verification/lab_sea/results/output.txt
768    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
769    o Added useSingleCpuIO option (see PARAMS.h).
770    o Updated useSingleCpuIO option in mdsio_writefield.F to
771      work with multi-field files, e.g., for single-file pickup.
772    o pkg/seaice:
773      - bug fix in growth.F: QNET for no shortwave case
774      - added HeffFile for specifying initial sea-ice thickness
775      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
776    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,

784    o dynamics: change definition of computational domain & adapt mom_fluxform
785      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
786    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
787        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
788        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
789        global_ocean.90x40x15 global_with_exf global_ocean_pressure
790        inverted_barometer solid-body.cs-32x32x1
791      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
792    
793    checkpoint48d_post
794    o in preparation for r*:
795     a) use pre-computed gradient of hydrostatic potential:
796        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
797     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
798        => affects results of glob_oce_pressure (different truncation error)  
799      update output.txt of ideal_2D_oce & global_ocean_pressure
800    
801    checkpoint48d_pre
802    o in preparation for r*:
803      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
804      pass the 2 comp. of the grad. as arguments to momentum S/R.
805      but for the moment, only used if it does not change the results.
806    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
807    
808    checkpoint48c_post
809    Modifications in treatment of initial flux forcing controls

817    o r* coordinate added in #ifdef NONLIN_FRSURF block.
818     (modification to pressure gradient not yet implemented)
819    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
820      (for U & V) that are used for vertical advection of momentum.
821    
822    checkpoint48a_post
823    o In preparation for r*, use temp. array to compute vertical transport
824       in flux-form momentum pkg. => change results of few test-exp.
825      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
826                        lab_sea, natl_box & plume_on_slope
827    
828    checkpoint48
829    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
830    
831    checkpoint47j_post
832    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
833    o moved adexch from forward_step to addummy_in_stepping
834    o added exch in ctrl_map_...
835    o aveFreq.=0. at end of cost_final to avoid overwrite in
836      reverse checkpointing loop
837    o Yet more changes in gmredi:
838      * adgmredi_calc_tensor
839        avoiding all recomputation of gmredi_slope_limit
840      * adgmredi_x/y/rtransport
841        added flag for excessive storing to avoid recomp. of
842        u/v/rtans, dTdx/y/z
843        -> this is not really necessary and very memory-consuming
844      * adgmredi_slope_psi:
845        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
846      * gmredi_slope_limit
847        re-activated full calculation of taperfct for case 'ac02'
848    o updating verification/ adjoints of carbon, global_ocean.90x40x15
849    
850    checkpoint47i_post
851    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
852    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
853      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
854    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
855    o gmredi: fix few bugs.
856    
857    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
858    This will be a good checkpoint to plug into the ecco-branch.
859    o few modif.'s to get latest version adjointed
860      (mainly kick out code in ini_linear_phisurf)
861    o modif's to run adjoint with exactConserv
862    o case GM_BOLUS_ADVEC should be cleaned
863      S/R gmredi_slope_psi should be cleaned
864    o verification/carbon now has exactConserv=.TRUE.
865    
866    checkpoint47g_post
867    o time-average AIM output: becomes independent from statvars time-average
868      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
869    o After TAF bug fix:
870      Tested adjoint of gmredi package.
871      Tests were done with checkpoint47 rather than with latest
872      checkpoint47f_post since the latter is broken for the adjoint
873      verification/carbon/ contains both ADM and TLM gradient checks.
874    Here they are, before they get changed/lost/stolen.
875    Mostly modif.'s to fix numerical sensitivities.
876    Gradient checks OK for
877    - GM_taper_scheme:
878      * clipping
879      * ac02
880      * linear
881      * glw91
882      * dm95
883      * ldd97
884    - GMREDI_OPTIONS:
885      * GM_VISBECK_VARIABLE_K
886      * GM_NON_UNITY_DIAGONAL
887      * GM_EXTRA_DIAGONAL
888      * GM_BOLUS_ADVEC
889    in conjunction with data.gmredi parameters to be checked in
890    in a few minutes under verification/carbon/code/
891    
892    checkpoint47f_post
893    Merging from release1_p10:
894    o modifications for using pkg/exf with pkg/seaice
895      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
896        and SEAICE_EXTERNAL_FLUXES
897      - pkg/exf CPP options EXF_READ_EVAP and
898        EXF_NO_BULK_COMPUTATIONS
899      - usage examples are Experiments 8 and 9 in
900        verification/lab_sea/README
901      - verification/lab_sea default experiment now uses
902        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
903    
904    checkpoint47e_post
905    o created a tag prior to creating a branch
906    
907    checkpoint47d_post
908    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
909      at the bottom boundary had an erroneous half slip boundary condition
910    o added bottom drag and no slip boundary condition capabilities to
911      oceanic pressure coordinates code
912    o added new verification experiment global_ocean_pressure, this experiment is
913      also described in the tutorial section of the manual
914    checkpoint47d_pre
915    
916    checkpoint47c_post
917    o Added a verification experiment for a global cubed-sphere ocean run
918      -  verification/global_ocean.cubed32x32x30
919      -  uses pkg/therm_seaice and pkg/bulk_forcing
920    
921    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
922    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
923      when using P-coordinate; only implemented for atmospheric config.
924    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
925      NOTES: requires option NONLIN_FRSURF to be "#define".
926    o update advect_xz/results/output.txt (left from checkpoint44g_post)
927    
928    checkpoint47b_post
929    Merging from release1_p9:
930    o pkg/seaice
931      - removed GOTO's and added taf directives
932      - double precision constants to reduce the g77 (Linux)
933        to F77 (SGI) differences reported in release1_p8
934    o tools/genmake
935      - added SGI options
936    o verification/testscript
937      - updated to that of checkpoint47a_post
938    o verification/global_ocean.90x40x15/input/eedata
939      - modified for SGI f77 compatibility
940    o verification/lab_sea
941      - added description of sea-ice model
942      - added missing matlab routines
943      - added test of thermodynamics parallelization
944    
945    checkpoint47a_post
946    o new pkg: aim_v23
947     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
948       for now, keep the same surface forcing as before.
949     - Part-Cell implemented into AIM; check that Heat & Water are conserved
950     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
951     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
952    o add diagnostic of surface correction term in monitor output
953    
954    o bulk_force and therm_seaice
955    - Two packages:  bulk_force (Bulk forcing)
956      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
957    - Earlier integration from Stephaine Dutkiewicz
958      and Patrick Heimbach.
959    - Two ifdef statements for compile time,
960       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
961    
962    checkpoint47
963    differentiable version of checkpoint46n_post
964    o bug fix in quasihydrostaticterms
965    o * "clean" adjoint code (in terms of extensive recomputations)
966        can now be obtained for all GMREDI options (i.e. for
967        - GM_VISBECK_VARIABLE_K
968        - GM_NON_UNITY_DIAGONAL
969        - GM_EXTRA_DIAGONAL
970        - GM_BOLUS_ADVEC )
971      * However, wrong gradient check problem remains unsolved.
972      * New CPP options have been introduced for different
973        tapering schemes
974    o external_fields_load now part of differentiation list
975    o pressure needs multiple storing;
976      would be nice to have store_pressure at beginning or
977      end of forward_step, e.g. by having phiHyd global (5-dim.)
978      (NB: pressure is needed for certain cases in find_rho,
979      which is also invoked through convective_adjustment).
980    o recomputations in find_rho for cases
981     'JMD95'/'UNESCO' or 'MDJWF' are OK.
982    o #define ATMOSPHERIC_LOADING should be differentiable
983    o ini_forcing shifted to begining of initialise_varia
984    o Incorporating QNVS line search routines into MITgcm
985      (this is separate code, and therefore not under pkg)
986      lsopt/, optim/
987    o Updated verification/carbon/
988      - #define GM_VISBECK_VARIABLE_K
989      - GM_taper_scheme    = 'ldd97'    
990    
991    checkpoint46n_post
992    Merging from release1_p8:
993    o verification/natl_box:
994      updating new external_fields_load routine
995    o New package: pkg/seaice
996      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
997      The sea-ice code is based on Hibler (1979-1980).
998      Two sea-ice dynamic solvers, ADI and LSR, are included.
999      In addition to computing prognostic sea-ice variables and diagnosing
1000      the forcing/external data fields that drive the ocean model,
1001      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1002      The implied surface heat flux is then stored in variable
1003      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1004      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1005      non-local transport term.  Because this call precedes model
1006      thermodynamics, temperature under sea-ice may not be "exactly" at
1007      the freezing point by the time theta is dumped or time-averaged.
1008      N.B.: fairly large differences in accuracy occur across
1009            different platforms/compilers; comparison between
1010            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1011            generated output gives:
1012       T           S           U           V
1013      C D M    c        m  s        m  s        m  s        m  s
1014      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
1015      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
1016      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
1017    
1018      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1019    o GAD:
1020      - generated new common blocks to account for call of
1021        same gad routines with differing traceridentities
1022        (needed to modify tracerIdentity indices in GAD.h)
1023      - generated separate common blocks for case useCubedSphereExchange
1024        (Department of Futurology)
1025      - parameter lists to gmredi_?transport: added tracerIdentity
1026      - added new key indices to tamc.h
1027    o external_fields_load:
1028      - added this routine to TAF list
1029      - needed to make some common blocks global and additional storing
1030        along the same lines as exf package (checkpoint_lev?_directives.h)
1031    o exf:
1032      updated external forcing package
1033      - bug fixes carried over from ecco-branch
1034        (missing OBCS_OPTIONS.h in two routines)
1035      - enable easy to use "no forcing".
1036      - added exf I/O for atmospheric loading
1037      - added exf I/O for runoff data
1038      - transfered scaling between exf <-> MITgcm to exf namelist
1039    o Adding new verification experiment global_with_exf.
1040      This verification experiment is almost identical to the
1041      global_ocean.90x40x15 experiment, except that it uses
1042      the exf (and cal) package instead of the
1043      external_fields_load routine (cf README file).
1044    
1045    checkpoint46m_post
1046    o modified testscript to return -- when there are no lines of "%MON" output
1047    o added new flag "quasiHydrostatic" for QH mode
1048      and new routine quasihydrostaticterms()
1049    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1050      New routine: mom_u_coriolis_nh()
1051    o fixed sign of non-hydrostatic metric terms in u and v equations.
1052      Depend on correct sign of gravitySign.
1053    o added work.pc* to .cvsignore in aim directories using ifc
1054    o introduced flag for controllin non-hydrostatic metric terms
1055    o removed gravitySign from PARM04
1056    o switched to g77/ifc from pgf77 in aim experiments
1057    
1058    checkpoint46l_post
1059    o made convective adjustment work with pressure coordinates:
1060     - changed the direction of k-loop in convective_adjustment.F for the
1061       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1062     - adjusted the reference pressure k-index in convective_adjustment.F
1063     - adjusted the convection condition in convect.F (in analogy to
1064       calc_ivdc.F)
1065     - convective_adjustment no longer computes anything on the halos
1066     - removed the warnings about negative salinity from find_rho.F and
1067       find_alpha.F; instead the new routine look_for_neg_salinity, called
1068       at the beginning of find_rho, find_alpha, and find_beta, does a
1069       check of the entire slice, if CPP-option
1070       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1071    checkpoint46l_pre
1072    
1073    checkpoint46k_post
1074    o fixed the verification/global_ocean.90x40x15 experiment:
1075     - new bathymetry (the world according to A., JMC, and M.)
1076     - new initial fields and forcing fields (*.bin files)
1077     - new POLY3.COEFFS (for the next release one should switch to a full
1078       equation of state: JMD95P or MDJWF)
1079     - fixed several errors and redundancies in the data file
1080     - experiment uses looped cells
1081     - added matlab directory with diagnostic scripts for plotting of output
1082    
1083    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1084     - read AIM physics parameters from a file (data.aimphys)
1085     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1086    
1087    checkpoint46j_post
1088    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1089    o move wVel computation at the end of the time step, in S/R integr_continuity
1090    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1091    o update timeave pkg for wVel diagnostic.
1092    checkpoint46j_pre
1093    
1094    checkpoint46i_post
1095    o Clean up AIM package (and keep the results unchanged):
1096      include CPP_OPTION and use IMPLICT NONE in all routines ;
1097      declare all the variables _RL ; use _d 0 for all numerical constants.
1098      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1099    
1100    checkpoint46h_post
1101    o cleaned up the use of rhoNil and rhoConst.
1102      - rhoNil should only appear in the LINEAR equation of state, everywhere
1103        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1104        and the dynamical equations are all divided by rhoConst
1105    o introduced new parameter rhoConstFresh, a reference density of fresh
1106      water, to remove the fresh water flux's dependence on rhoNil. The default
1107      value is 999.8 kg/m^3
1108    o cleanup up external_forcing.F and external_forcing_surf.F
1109      - can now be used by both OCEANIC and OCEANICP
1110    checkpoint46h_pre
1111    
1112     Added code to convert surface volume flux (fresh water) into
1113     a mass flux when using P coordinates in the ocean (OCEANICP).
1114     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1115    
1116    checkpoint46g_post
1117    o Include a new diagnostic variable phiHydLow for the ocean model
1118      - in z-coordinates, it is the bottom pressure anomaly
1119      - in p-coordinates, it is the sea surface elevation
1120      - in both cases, these variable have global drift, reflecting the mass
1121        drift in z-coordinates and the volume drift in p-coordinates
1122      - included time averaging for phiHydLow, be aware of the drift!
1123    o depth-dependent computation of Bo_surf for pressure coordinates
1124      in the ocean (buoyancyRelation='OCEANICP')
1125      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1126        Theta, Salinity, and Pressure in the parameter list. This routine is
1127        presently contained in find_rho.F. This routine does not give the
1128        correct density for 'POLY3', which would be a z-dependent reference
1129        density.
1130    o cleaned up find_rho
1131      - removed obsolete 'eqn' from the parameter list.
1132    o added two new verification experiments: gop and goz
1133      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1134    checkpoint46g_pre
1135    
1136    checkpoint46f_post
1137    o Enable tangent linear (forward mode) gradient checks:
1138      - extended active file handling to g_... files
1139      - added TANGENT_SIMULATION to theSimulationMode
1140      - extended grdchk package accordingly
1141    o added tangent linear setup in verification/carbon/code_ftl
1142    o added adjoint setup in verification/front_relax/code_ad
1143    
1144    checkpoint46e_post
1145    o Added new equation of state -> MDJWF
1146      - EOS of McDougall et al., 2002, JAOT, submitted
1147      - caveat: the equation of state is only valid for a smaller (more
1148        realistic?) range of values than JMD95P/Z and UNESCO
1149      - added masks to the calculation of pressure in store_pressure
1150      - added more check values for density in check_eos (ini_eos.F), some of
1151        the old check values are out of the range of the MDJWF-eos, so don't
1152        expect perfect matches for those
1153    checkpoint46e_pre
1154    
1155    checkpoint46d_post
1156    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1157      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1158      case of pressure coordinates. eosType='JMD95Z' in
1159      combination with buoyancyRelation='OCEANICP' now causes an error.
1160    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1161      in find_alpha/beta.
1162    checkpoint46d_pre
1163    
1164    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1165      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1166    
1167    checkpoint46c_post
1168    o Changes necessary for ocean in p-coordinates
1169     -  Added new buoyancy relation = 'OCEANICP'
1170     -  Added new parameters = gravitySign (this used to be contained inside
1171        the factor dRdZ which I added when we first switched to R coordinates).
1172     X GM/Redi is not compatible (yet)
1173     X bottom drag and no-slip need to be debugged.
1174    checkpoint46c_pre
1175    
1176    checkpoint46b_post
1177    o Added new equation of state -> JMD95Z and JMD95P
1178      - EOS of Jackett and McDougall, 1995, JAOT
1179      - moved all EOS parameters into EOS.h
1180      - new routines ini_eos.F, store_pressure.F
1181    o Added UNESCO EOS, but not recommended because it requires
1182      in-situ temperature (see JMD95)
1183    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1184      unesco.f to be used with POLY3
1185    checkpoint46b_pre
1186    
1187    checkpoint46a_post
1188    o Added (atmospheric) pressure loading
1189      - new field in FFIELDS.h, etc...
1190      - new cpp flag ATMOSPHERIC_LOADING
1191    o Changed hFacC to _hFacC in calc_phi_hyd.F
1192    o Added SHORTWAVE_HEATING to some files for consistency
1193    checkpoint46a_pre
1194    
1195    checkpoint46
1196    further merges from release1_p5
1197    o new ctrl package
1198      - adopted from ECCO environment to enable optimization
1199      - added Eliassen Palm fluxes to controls
1200    o added Eliassen Palm flux controls to gradient check package
1201    o cost package
1202      - Compatible with new ctrl package
1203      - added Eliassen Palm cost hooks
1204      - modif's of existing cost functions
1205    o Adjoint-related bug fixes in kpp:
1206      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1207      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1208    o autodiff package
1209      - flow directives:
1210        + new for S/R do_the_model_io
1211        + enhanced for S/R checkpoint
1212        + new gmredi.flow
1213      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1214        disable adcommon.h/g_common.h by default.
1215      - fixed problem for adjoint of global_max
1216    o modified verification/carbon/
1217    o New setup for adjoint of global_ocean
1218    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1219    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1220    o incorporated hooks for sponge layer code (external_forcing.F)
