4      ==============================      ==============================
5    
6    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
7    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
8      atmospheric model (AIM) to use it ; add a "slab ocean" component.
9    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
10    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
11    o extending useSingleCpuIO option to work with new exch2 I/O format
12      - old-style, missing-tile I/O is still accessible by defining CPP
13        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
14    o monitor package can write to NetCDF files and/or STDOUT
15    o fix re-definition bug in MNC_GRID_INIT_ALL()
16    o doc/api_reference added
17      - a framework for building an API Reference Manual using all
18        the "protex" comments embedded in the code
19      - see pkg/generic_advdiff, pkg/mnc for examples
20    o MNC:
21      - make myThid the last argument for all subroutines
22      - new default for the grid files: NO halos
23      - add useMNC and other run-time flags
24      - separate per-file-group handling of the unlimited dimension
25      - early initialization of MNC w/ flags read at the eeboot stage
26        and lookup tables set in initialize_fixed
27      - write all MNC output to a freshly-created directory
28    o thermodynamics sea-ice (thsice) is now tested with testreport.
29    o test exp. advect_cs: use the standard cs32 grid ; update output.
30    o Added functionality to grdchk:
31      pick global i,j,k position (or nearest wet) where to perform check.
32    
33    checkpoint52l_post
34    o new land formulation:
35      a) use ground enthalpy as prognostic variable to ensure exact
36         energy conservation.
37      b) account for water temperature and for latent heat of freezing
38         in all processes (rain, run-off, ground storage)
39      c) compute surface and ground temperature implicitly.
40    o aim_v23 modification for new land model:
41      a) Treat separately land / ocean / sea-ice surface fluxes
42         to allow implicit computation of land & sea-ice surface temp.
43      b) add snow precipitation.
44    checkpoint52l_pre
45    
46    o fix problem (when 1 tile is empty) in min/max monitor.

48    o no restoring terms under ice for pkg/seaice
49    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
50    o bug fix for pkg/seaice pickups
51    o change MNC call locations and add coordinate attributes
52    o mask vorticity at the corner ; affects global_ocean.cs output
53    o fix ini_curvilinear_grid ; test CS experiments with mpi
54    o aim.5l_cs: modify sea-ice fraction input file ; update output
55    o exf: Adding simple range check routine for exf fields after read
56    
57    checkpoint52k_post
58    o removed top-level directory "diags"
59      - we migrated these functions to pkg/timeave a long time ago
60    o fixed bug introduced in pkg/monitor
61    o accuracy ctrlprec = 32 insuffient for gradient checks using
62      averaged fields (I/O via cost_averages)
63      -> use ctrl.h in active_file*.F to control I/O precision.
64    o paramter list of CALL ADTHE_MAIN_LOOP
65    o added initial do_the_model_io to ecco
66    o set all ...Freq to zero after cost_final
67      taveFreq, dumpFreq, pChkptFreq
68    o MAIN and ECCO differentiability restored
69    
70    checkpoint52j_post
71    o fix nchklev in tamc.h for global_ocean...
72    o Bringing flow and store directives up-to-date
73    o Really weird thing!
74      call do_the_model_io from the_main_loop with parameters
75      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
76      TAF places a faulty re-call of initialise_varia
77      after cost_final call which should not be there!
78    checkpoint52j_pre
79    
80    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
81      error messages
82    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
83    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
84      debug output
85    o modfied mdsio_writefield.F to handle non-global files under exch2
86    o update AIM Cubed-Sphere exp (aim.5l_cs):
87      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
88    o update AIM Equatorial Channel exp:
89      use standard aim_v23 pkg and change the SST fields to be more realistic.
90    o globalFile now works with exch2
91    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
92      mon_vort3.F to make exch2 friendly with >1 tile per cube face
93    o limit timeave output for hi-res integrations
94    
95    checkpoint52i_post
96    o removed CPP_EEOPTIONS.h from verification/*/code
97    o updated the tiling for global_ocean_pressure
98    checkpoint52i_pre
99    
100    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
101      the old pkg/aim).
102    
103    checkpoint52h_pre
104    o shortened offending lines in exch2_send_rx?.template
105    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
106    o genmake2: add build & execute test for NetCDF code
107    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
108      old grid files, moved CPP_EEMACROS.h to pkg/exch2
109    o added useSingleCPUIO flag to monitor.F and mon_out.F
110    o added temporary hack for sea-ice dynamics on the cube:
111      metric terms are ignored and it is assumed that
112      there is no sea-ice on cube faces 1, 2, 4, and 5.
113    
114    checkpoint52f_post
115    o added exch2 cube routines to pkg/exch2
116    o modified hs94.cs-32x32x5 to use it
117    o added new grid files to hs94.cs-32x32x5
118    checkpoint52f_pre
119    
120    checkpoint52e_post
121    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
122      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
123    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
124      to work with implicit vertical advection and AB ;
125    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
126    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
127     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
128    checkpoint52e_pre
129    
130    o fix bug in impldiff when Nr=1 or Nr=2.
131    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
132    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
133    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
134      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
135    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
136    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
137    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
138    
139    checkpoint52d_post
140    o re-tiled many expts to allow comparison in multi-processor mode
141      - updated output accordingly
142      - changed hs94.128x64x5 to use intial T from file rather than use the
143        random number generator
144    o add infrastructure in model routines for fizhi and gridalt packages
145    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
146    o changes to permit hi-res, cubed-sphere, configuration
147      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
148      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
149      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
150        of surface winds for the cube
151      (A verification experiment, based on global_ocean.cs32x15, but with
152       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
153       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
154       complete with example surface forcing files and matlab scripts to look
155       at the output and compare it with that of global_ocean.cs32x15.)
156    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
157       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
158       to conform to the common rule.
159    o check-in the first version of the coupler + interfaces for multi-components
160       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
161       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
162       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
163       - ocean and atmos. share the same horizontal grid (no interpolation).
164       - exchanges between component and coupler is done in forward_step
165    o new verification experiment, cpl_aim+ocn:
166       coupled ocean - AIM atmosphere on cs32 grid.
167    
168    checkpoint52d_pre
169    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
170    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
171    
172    checkpoint52c_post
173    o Fixing OPTIONS files for use of exf:
174      - ALLOW_ECCO not needed
175      - ECCO_CPPOPTIONS.h should not be included from
176        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
177        as has been the case in the past
178      - All cal/exf related options are currently set in
179        single header file. Should remain so until we
180        agree on a consistent new policy.
181    o Removed all CPP options for cal package.
182      cal has no more CPP options.
183    o modified STOREs in GAD_ADVECTION
184    o corrected key comp. for passkey
185    
186    checkpoint52b_post
187    o new version: "thsice" of thermodynamic sea-ice pkg:
188     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
189     - modify fluxes but do not change theta directly;
190     - light cleaning of bulk_force pkg (still needed with thsice).
191     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
192       + output_thsice.txt to test thsice & bulk_force pkgs.
193    o put back grid & coriolis monitor output.
194    checkpoint52b_pre
195    
196    o call "do_the_model_io" at the beginning (=> dump initial state)
197    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
198    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
199      (need info on NUMBER_OF_PTRACERS)
200    o missing PTRACERS headers in some routines
201    o default tamc.h in pkg/autodiff supposed to crash
202      to ensure proper customization
203    
204    checkpoint52a_post
205    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
206      - moved surfaceTendencyTice from pkg/seaice to main code
207      - subroutine FREEZE_SURFACE now limits only surface temperature
208        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
209        => new output.txt for global_ocean.cs32x15 & global_with_exf
210      - keep the old version of FREEZE for backward compatibility;
211        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
212      - corresponding modifs for TAF directives
213    o added surface flux output variables to TIMEAVE_STATVARS
214    o time-averaged output for pkg/ptracers
215    o fix problem with ECCO-related divided adjoint

217      but no warning issued by TAF
218    
219    checkpoint52a_pre
220    o some bug fixes for #undef REAL4_IS_SLOW
221    
222    checkpoint52 = ecco_c52_e35
223    o after testing adjoints of checkpoint51u_post
224    
225    checkpoint51u_post
226    o this is the post-merge tag of the ecco-branch
227      (needs another clean checkout and re-testing)
228    o various natl_box_adjoint configs and results
229      but no input fields
230    o obcs adjoint not yet merged!
231    o adding ECCO global 1x1 and 2x2 degree configs
232    o updated/extended some store directives for seaice
233    o pkg/ecco now containes ecco-specific part of cost function
234    o top level routines the_main_loop, forward_step
235      supersede those in model/src/
236      previous input data.cost now in data.ecco
237      (new namelist ecco_cost_nml)
238    o in ctrl/ cleaned some cross-dependencies and updated CPP options
239    
240    checkpoint51t_post
241    o this is the pre-merge tag of the ecco-branch
242    
243    checkpoint51s_post
244    o cleanup: removed various obsolete #define-s
245    o pkg/grdchk
246      - renamed 'ph-grd 3' to 'grad-res'
247      - merged from ecco-branch
248        (remaining bug fixes for obcs gradient checks)
249      - additional high-precision output for testreport
250        (grep for 'precision_grdchk_result')
251    
252    checkpoint51r_post
253    o cleaned up or removed CPP_OPTIONS.h files
254    o updated results for some of the tests to reflect the new
255      optfiles (-ieee: -O0 instead of -O3)
256    
257    checkpoint51q_post
258    o cd_code:
259      - moved cd_scheme.F -> cd_code_scheme.F
260      - separate read_checkpoint from cd_code_ini_vars.F
261      - separated cd_code part from write_checkpoint
262      - updated AD_SOURCE, generated .flow
263      - added CD_CODE_VARS.h to the_main_loop
264      - Moving cd_code specific store dir.s to pkg/cd_code
265    o ctrl package totally restructured
266      - pack/unpack now optional and decoupled from
267        xx_/adxx_ I/O
268      - ctrl_pack/unpack cleaned
269        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
270      - confined inclusion of AD_CONFIG.h to where necessary.
271    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
272    
273    checkpoint51p_post
274    o create initial cd_code package
275      - WARNING: the initialization of fields within packages
276        is broken because INI_FIELDS (where READ_CHECKPOINT is
277        called) is called *before* PACKAGES_INIT_VARIABLES.
278        This seems to be backwards since
279        1) its important to initially zero the entire field including
280           the "halo" region
281        2) zeroing needs to be done *before* reading pickup info
282           and the pickup call might or might not happen in any
283           particular run
284      - this needs an overhaul for R2
285    o cleanup verification/*/code/GMREDI_OPTIONS.h
286    o cleanup testreport
287    
288    checkpoint51o_post
289    o bringing AD-related verif's up to date with genmake2

293      - (front_relax/ )
294    o (more) consistent directory structure for AD-related verif.'s
295    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
296    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
297    o bug fix in find_alpha.F for MDJWF:
298      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
299        change rho -> rho-rhoConst
300      - replace call find_rho to find_rhonum
301    o initialisation of rFlx extended to full array (required by TAF)
302      and shifted to thermodynamics
303    o removed PTRACERS.h in ptracers routine

319      - moved surfaceTendencyTice from pkg/seaice to main code
320      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
321      - subroutine FREEZE now limits only surface temperature
322        (this means new output.txt for global_ocean.90x40x15,
323         global_ocean.cs32x15, and global_with_exf)
324    o added surface flux output variables to TIMEAVE_STATVARS
325    
326    checkpoint51n_pre
327    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

348    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
349    o enable to apply restoring on S & T only in a latitude band.
350    o update output (external_forcing_surf modif. change truncation errors)
351       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
352    
353    checkpoint51k_post
354    o change default to: useNHMTerms=.FALSE.

414        "USE_EXF_INTERPOLATION" to pkg/exf.
415      - This is a temporary Cartesian-grid hack until
416        the super-duper ESMF coupler becomes available.
417      - See verification/global_with_exf/README for usage example.
418      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
419        flags and modified pkg/seaice accordingly.
420    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
421        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
422        non-local transport term.
423    
424    checkpoint51e_post
425    o pkg/mom_vecinv:

432    o AIM : add stratospheric drag in the upper level
433    
434    checkpoint51d_post
435    o change function ILNBLNK (=> last non-blank char.) to return zero
436      (instead of the string length) when the string. char is empty
437    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
438    o modif's to restore TAMC compatibility
439      - avoid "_d" constructs in PARAMETER declarations
440      - avoid interrupting lines by comment lines
441    o Use cluster local disks for purely local I/O
442      vs. globally visible disks needed for ctrl stuff
443      (merged from ecco-branch)
444      - new active_file_loc... and mdsio_..._loc routines
445      - affected packages: autodiff, ctrl, grdchk, mdsio
446    
447    checkpoint51c_post
448    o introducing integer flag debugLevel
449      - debLevZero: suppress all output
450      - debLevA: standard
451      - debLevB: equivalent to current debugMode=.TRUE.
452    o introducing pathname variable mdsioLocalDir for mdsio
453      that can be specified at runtime
454      (relevant for cluster I/O to local disk)
455    `
456    >>>checkpoint51b_post
457    adjoint of ptracers
458    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
459    o extended state in checkpoint_lev?, etc.
460    o alternative ctrl/cost with tr1 or ptracer
461    o new comlev1_bibj_ptracers
462    o new ptracers.flow
463    o made ptracers_forcing same as external_forcing_s
464    o added verification for adjoint with ptracers
465      - adm. grdchk fail so far
466      - tlm. grdchk OK
467      - checked tapelev/comlev recomputations: OK
468    <<<checkpoint51b_pre
469    
470    checkpoint51a_post
471    o added code for biogeochemistry package
472      - new pkgs: dic, gchem
473      - new subroutine in ptracers
474    o modify code for biogeo packages
475      - in model/src and pkg/ptracers
476    
477    checkpoint51
478    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
479      - autodiff, ctrl, exf, grdchk, seaice
480      kept separate packages
481      - cost, ecco, obcs
482    o updating verification/internal_wave, verification/lab_sea
483      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
484    
485    checkpoint50i_post
486    o Preparing next differentiable checkpoint and sync
487      of MAIN vs. ecco-branch
488      - 1st step: this one is differentiable
489      - 2nd step: next(! not this) checkpoint will have updated packages
490                  from ecco-branch)
491    
492    checkpoint50h_post
493    o new package "land": provide surface BC for AIM.
494    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
495    o AIM: use true log-P extrapolation for near surface temp (= as in
496        F.Molteni paper) ; update aim.5l_cs output.
497    o New variable in PARM03 for more flexible pickups
498    o somewhat cleaned package initialisation sequence for
499      ctrl/ cost/ ecco/ in packages_... routines
500    
501    checkpoint50g_post
502    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
503      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
504      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
505        made the default because of faster convergence than ADI
506    
507    checkpoint50f_post
508    o exf totally restructured
509      - replaced all exf_set_ routines by one generic exf_set_gen.F
510        and made sure it's still differentiable
511      - split exf_getffields.F into new exf_bulkformulae.F
512      - exf_inscal_/exf_outscal_ suffixes consistent with field names

517          + change Evap over land. (update aim.5l_cs output)
518     o added missing .cvsignores and made uniform across expts
519     o changed configuration of tidal_basin_2d expt
520     o added pkg/debug functions for tracing code in fatal crashes
521     o tidied pkg/monitor to use MONITOR_OPTIONS.h
522     o new fn in pkg/monitor to stop model if solution grows too big
523     o removed lots of single quotes from comments
524    
525    checkpoint50e_post
526    o make KPP work with PTRACERS
527     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
528       nearly a copy of kpp_transport_s
529     - there is no analogue to SurfaceTendencyS, so I have to use
530       gPtr(of the surface layer) instead
531    o add a new platform SunFire+mpi (SunFire 15000) to genmake
532    checkpoint50e_pre
533    
534    checkpoint50d_post
535    o change kpp output from multiple-record state files to single-record state
536      files analogous to write_state.F
537    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
538      analogous to the cg2d-related output.
539    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
540      so that writing to internal file fn (with length 512) fails.
541    checkpoint50d_pre
542    
543    checkpoint50c_post
544    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
545    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
546    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
547    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
548    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
549    
550    checkpoint50c_pre
551    Merging from release1_p13:
552    o bug fix for pkg/seaice dynamic solver
553    o Added SEAICE_initialHEFF to pkg/seaice
554    
555    checkpoint50b_post
556    o store u*,v* in gU,V instead of in guNm1,gvNm1
557    o in order to put the momForcing out of the Adams-Bashforth:
558      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
559      to timestep.F
560    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
561    o re-generate output for highly sensitive test-exp:
562       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
563    
564    checkpoint50b_pre
565    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
566    o corrected CPP option mismatch in exf_Bulk... functions for case
567      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
568    
569    checkpoint50a_post
570    o Bug fix for merging between c50 and KPP.
571      ikey was passed from thermodynamics to kpp_calc via
572      common block rather than being recomputed in kpp_calc,
573      in contradiction with new key itdkey.
574      New key ikppkey created, and tamc.h headers updated.
575    
576    checkpoint50
577    - 2nd step of merge with ecco-branch:
578      merge changes in ecco-branch back into main trunk
579    - bug fix in find_alpha
580    - more storing in gmredi_calc_tensor.F, kpp_routines.F
581    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
582    - merged some sliced AD support routines
583    
584    checkpoint49
585    merged from ecco-branch:
586    o exf:
587      - Enable initialisation of forcing fields to constant
588        (runtime) values.
589      - in exf_getffields.F
590        Reduce i-/j-loop to interior domain, discarding overlaps.
591        That also fixes wrong TAF-key computations for key_1, key_2
592        with bulf formulae.
593      - exf_init.F modify #ifdef for exf_init_evap
594      - exf_getffieldrec.F, ctrl_getrec.F
595        The following INT-usages are not safe:
596          fldsecs  = int(fldsecs/fldperiod)*fldperiod
597          fldcount = int(fldsecs/fldperiod) + 1
598        and were modified.
599    o autodiff: checkpoint_lev...
600      - updated storing for bulk formulae (some arrays were missing)
601      - added state for seaice package
602      - synchronized with main branch
603    o DIVA:
604      Modif.s in
605      - the_main_loop.F
606      - the_model_main.F
607      and added cost_final_restore.F cost_final_store.F
608      o With these changes, it is possible to fully separate
609        the first forward run to compute the cost function (mdthe_main_loop)
610        and adjoint runs over individual DIVA intervals (adthe_main_loop)
611        into separate model executions.
612        This enables better tuning of DIVA to given queue sizes.
613      o Loss of cost function value in consecutive DIVA runs is
614        fixed by storing to 'costfinal' file.
615      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
616        beginning/end of adjoint integration is accounted for.
617      The current changes apply to TAF-1.4.26.
618      TAF has one remaining bug, requiring one manual change
619      (see MITgcm manual).
620    o cal: synchronized between MAIN and ecco-branch
621    
622    checkpoint48i_post
623    o Changes to restore differentiability of code w.r.t. previous tag
624      (mostly adding new routines to make list and replacing
625      pressure by totPhiHyd).
626    o Updated and merged grdchk package
627      - has both ADM and TLM checks
628      - works for single- and multi-proc.
629      - output cleaned
630      - worked successfully for parallel DIVA
631    o genmake:
632      - Adding -platform=SP4
633      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
634    o Modif. for DIVA:
635      ctrl_unpack should not be called in intermediate DIVA interval.
636      (similar thing would apply for active files such as
637      tbar, sbar, psbar, which should not be reinitialised;
638      only relevant for ecco-branch)
639    
640    checkpoint48h_post
641    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
642    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
643    o Added SEAICE_initialHEFF to pkg/seaice
644    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
645    
646    checkpoint48g_post
647    --- EOS:
648    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
649      store total Potential in totPhyHyd for diagnostics & EOS.
650    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
651    --- Pressure/geopotential gradient:
652    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
653    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
654      ( changes results of global_ocean_pressure )
655    o NLFS + z-coord.: add eta*Rho' contribution.
656    o accurate phiHyd when using interface-W at the middle between 2 centers
657     ( changes results of ideal_2D_oce )
658    o includes r* 2nd term in potential gradient.
659    
660    checkpoint48f_post
661    Merging from release1_p12:
662    o Modifications for using pkg/exf with pkg/seaice
663      - improved description of the various forcing configurations

665      - units/sign fix for evap computation in exf_getffields.F
666      - updated verification/global_with_exf/results/output.txt
667    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
668      (SBO) core products, including oceanic mass, center-of-mass,
669      angular, and bottom pressure (see pkg/sbo/README.sbo).
670    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
671      to avoid negative values in shallow regions.
672      - updated verification/natl_box/results/output.txt
673      - updated verification/lab_sea/results/output.txt
674    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
675    o Added useSingleCpuIO option (see PARAMS.h).
676    o Updated useSingleCpuIO option in mdsio_writefield.F to
677      work with multi-field files, e.g., for single-file pickup.
678    o pkg/seaice:
679      - bug fix in growth.F: QNET for no shortwave case
680      - added HeffFile for specifying initial sea-ice thickness
681      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
682    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
683      kpp_transport_t.F, forward_step.F, and the_main_loop.F
684    o pkg/seaice:
685      - adjoint-friendly modifications
686      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
687    
688    checkpoint48e_post
689    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
690    o dynamics: change definition of computational domain & adapt mom_fluxform
691      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
692    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
693        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
694        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
695        global_ocean.90x40x15 global_with_exf global_ocean_pressure
696        inverted_barometer solid-body.cs-32x32x1
697      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
698    
699    checkpoint48d_post
700    o in preparation for r*:
701     a) use pre-computed gradient of hydrostatic potential:
702        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
703     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
704        => affects results of glob_oce_pressure (different truncation error)  
705      update output.txt of ideal_2D_oce & global_ocean_pressure
706    
707    checkpoint48d_pre
708    o in preparation for r*:
709      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
710      pass the 2 comp. of the grad. as arguments to momentum S/R.
711      but for the moment, only used if it does not change the results.
712    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
713    
714    checkpoint48c_post
715    Modifications in treatment of initial flux forcing controls
716    to avoid extra storing of flux fields.
717    
718    checkpoint48c_pre
719    o Added tidal_basin_2d experiment (currently 1D!)
720    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
721    
722    checkpoint48b_post
723    o r* coordinate added in #ifdef NONLIN_FRSURF block.
724     (modification to pressure gradient not yet implemented)
725    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
726      (for U & V) that are used for vertical advection of momentum.
727    
728    checkpoint48a_post
729    o In preparation for r*, use temp. array to compute vertical transport
730       in flux-form momentum pkg. => change results of few test-exp.
731      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
732                        lab_sea, natl_box & plume_on_slope
733    
734    checkpoint48
735    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
736    
737    checkpoint47j_post
738    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
739    o moved adexch from forward_step to addummy_in_stepping
740    o added exch in ctrl_map_...
741    o aveFreq.=0. at end of cost_final to avoid overwrite in
742      reverse checkpointing loop
743    o Yet more changes in gmredi:
744      * adgmredi_calc_tensor
745        avoiding all recomputation of gmredi_slope_limit
746      * adgmredi_x/y/rtransport
747        added flag for excessive storing to avoid recomp. of
748        u/v/rtans, dTdx/y/z
749        -> this is not really necessary and very memory-consuming
750      * adgmredi_slope_psi:
751        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
752      * gmredi_slope_limit
753        re-activated full calculation of taperfct for case 'ac02'
754    o updating verification/ adjoints of carbon, global_ocean.90x40x15
755    
756    checkpoint47i_post
757    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
758    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
759      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
760    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
761    o gmredi: fix few bugs.
762    
763    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
764    This will be a good checkpoint to plug into the ecco-branch.
765    o few modif.'s to get latest version adjointed
766      (mainly kick out code in ini_linear_phisurf)
767    o modif's to run adjoint with exactConserv
768    o case GM_BOLUS_ADVEC should be cleaned
769      S/R gmredi_slope_psi should be cleaned
770    o verification/carbon now has exactConserv=.TRUE.
771    
772    checkpoint47g_post
773    o time-average AIM output: becomes independent from statvars time-average
774      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
775    o After TAF bug fix:
776      Tested adjoint of gmredi package.
777      Tests were done with checkpoint47 rather than with latest
778      checkpoint47f_post since the latter is broken for the adjoint
779      verification/carbon/ contains both ADM and TLM gradient checks.
780    Here they are, before they get changed/lost/stolen.
781    Mostly modif.'s to fix numerical sensitivities.
782    Gradient checks OK for
783    - GM_taper_scheme:
784      * clipping
785      * ac02
786      * linear
787      * glw91
788      * dm95
789      * ldd97
790    - GMREDI_OPTIONS:
791      * GM_VISBECK_VARIABLE_K
792      * GM_NON_UNITY_DIAGONAL
793      * GM_EXTRA_DIAGONAL
794      * GM_BOLUS_ADVEC
795    in conjunction with data.gmredi parameters to be checked in
796    in a few minutes under verification/carbon/code/
797    
798    checkpoint47f_post
799    Merging from release1_p10:
800    o modifications for using pkg/exf with pkg/seaice
801      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
802        and SEAICE_EXTERNAL_FLUXES
803      - pkg/exf CPP options EXF_READ_EVAP and
804        EXF_NO_BULK_COMPUTATIONS
805      - usage examples are Experiments 8 and 9 in
806        verification/lab_sea/README
807      - verification/lab_sea default experiment now uses
808        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
809    
810    checkpoint47e_post
811    o created a tag prior to creating a branch
812    
813    checkpoint47d_post
814    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
815      at the bottom boundary had an erroneous half slip boundary condition
816    o added bottom drag and no slip boundary condition capabilities to
817      oceanic pressure coordinates code
818    o added new verification experiment global_ocean_pressure, this experiment is
819      also described in the tutorial section of the manual
820    checkpoint47d_pre
821    
822    checkpoint47c_post
823    o Added a verification experiment for a global cubed-sphere ocean run
824      -  verification/global_ocean.cubed32x32x30
825      -  uses pkg/therm_seaice and pkg/bulk_forcing
826    
827    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
828    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
829      when using P-coordinate; only implemented for atmospheric config.
830    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
831      NOTES: requires option NONLIN_FRSURF to be "#define".
832    o update advect_xz/results/output.txt (left from checkpoint44g_post)
833    
834    checkpoint47b_post
835    Merging from release1_p9:
836    o pkg/seaice
837      - removed GOTO's and added taf directives
838      - double precision constants to reduce the g77 (Linux)
839        to F77 (SGI) differences reported in release1_p8
840    o tools/genmake
841      - added SGI options
842    o verification/testscript
843      - updated to that of checkpoint47a_post
844    o verification/global_ocean.90x40x15/input/eedata
845      - modified for SGI f77 compatibility
846    o verification/lab_sea
847      - added description of sea-ice model
848      - added missing matlab routines
849      - added test of thermodynamics parallelization
850    
851    checkpoint47a_post
852    o new pkg: aim_v23
853     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
854       for now, keep the same surface forcing as before.
855     - Part-Cell implemented into AIM; check that Heat & Water are conserved
856     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
857     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
858    o add diagnostic of surface correction term in monitor output
859    
860    o bulk_force and therm_seaice
861    - Two packages:  bulk_force (Bulk forcing)
862      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
863    - Earlier integration from Stephaine Dutkiewicz
864      and Patrick Heimbach.
865    - Two ifdef statements for compile time,
866       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
867    
868    checkpoint47
869    differentiable version of checkpoint46n_post
870    o bug fix in quasihydrostaticterms
871    o * "clean" adjoint code (in terms of extensive recomputations)
872        can now be obtained for all GMREDI options (i.e. for
873        - GM_VISBECK_VARIABLE_K
874        - GM_NON_UNITY_DIAGONAL
875        - GM_EXTRA_DIAGONAL
876        - GM_BOLUS_ADVEC )
877      * However, wrong gradient check problem remains unsolved.
878      * New CPP options have been introduced for different
879        tapering schemes
880    o external_fields_load now part of differentiation list
881    o pressure needs multiple storing;
882      would be nice to have store_pressure at beginning or
883      end of forward_step, e.g. by having phiHyd global (5-dim.)
884      (NB: pressure is needed for certain cases in find_rho,
885      which is also invoked through convective_adjustment).
886    o recomputations in find_rho for cases
887     'JMD95'/'UNESCO' or 'MDJWF' are OK.
888    o #define ATMOSPHERIC_LOADING should be differentiable
889    o ini_forcing shifted to begining of initialise_varia
890    o Incorporating QNVS line search routines into MITgcm
891      (this is separate code, and therefore not under pkg)
892      lsopt/, optim/
893    o Updated verification/carbon/
894      - #define GM_VISBECK_VARIABLE_K
895      - GM_taper_scheme    = 'ldd97'    
896    
897    checkpoint46n_post
898    Merging from release1_p8:
899    o verification/natl_box:
900      updating new external_fields_load routine
901    o New package: pkg/seaice
902      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
903      The sea-ice code is based on Hibler (1979-1980).
904      Two sea-ice dynamic solvers, ADI and LSR, are included.
905      In addition to computing prognostic sea-ice variables and diagnosing
906      the forcing/external data fields that drive the ocean model,
907      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
908      The implied surface heat flux is then stored in variable
909      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
910      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
911      non-local transport term.  Because this call precedes model
912      thermodynamics, temperature under sea-ice may not be "exactly" at
913      the freezing point by the time theta is dumped or time-averaged.
914      N.B.: fairly large differences in accuracy occur across
915            different platforms/compilers; comparison between
916            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
917            generated output gives:
918       T           S           U           V
919      C D M    c        m  s        m  s        m  s        m  s
920      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
921      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
922      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
923    
924      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
925    o GAD:
926      - generated new common blocks to account for call of
927        same gad routines with differing traceridentities
928        (needed to modify tracerIdentity indices in GAD.h)
929      - generated separate common blocks for case useCubedSphereExchange
930        (Department of Futurology)
931      - parameter lists to gmredi_?transport: added tracerIdentity
932      - added new key indices to tamc.h
933    o external_fields_load:
934      - added this routine to TAF list
935      - needed to make some common blocks global and additional storing
936        along the same lines as exf package (checkpoint_lev?_directives.h)
937    o exf:
938      updated external forcing package
939      - bug fixes carried over from ecco-branch
940        (missing OBCS_OPTIONS.h in two routines)
941      - enable easy to use "no forcing".
942      - added exf I/O for atmospheric loading
943      - added exf I/O for runoff data
944      - transfered scaling between exf <-> MITgcm to exf namelist
945    o Adding new verification experiment global_with_exf.
946      This verification experiment is almost identical to the
947      global_ocean.90x40x15 experiment, except that it uses
948      the exf (and cal) package instead of the
949      external_fields_load routine (cf README file).
950    
951    checkpoint46m_post
952    o modified testscript to return -- when there are no lines of "%MON" output
953    o added new flag "quasiHydrostatic" for QH mode
954      and new routine quasihydrostaticterms()
955    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
956      New routine: mom_u_coriolis_nh()
957    o fixed sign of non-hydrostatic metric terms in u and v equations.
958      Depend on correct sign of gravitySign.
959    o added work.pc* to .cvsignore in aim directories using ifc
960    o introduced flag for controllin non-hydrostatic metric terms
961    o removed gravitySign from PARM04
962    o switched to g77/ifc from pgf77 in aim experiments
963    
964    checkpoint46l_post
965    o made convective adjustment work with pressure coordinates:
966     - changed the direction of k-loop in convective_adjustment.F for the
967       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
968     - adjusted the reference pressure k-index in convective_adjustment.F
969     - adjusted the convection condition in convect.F (in analogy to
970       calc_ivdc.F)
971     - convective_adjustment no longer computes anything on the halos
972     - removed the warnings about negative salinity from find_rho.F and
973       find_alpha.F; instead the new routine look_for_neg_salinity, called
974       at the beginning of find_rho, find_alpha, and find_beta, does a
975       check of the entire slice, if CPP-option
976       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
977    checkpoint46l_pre
978    
979    checkpoint46k_post
980    o fixed the verification/global_ocean.90x40x15 experiment:
981     - new bathymetry (the world according to A., JMC, and M.)
982     - new initial fields and forcing fields (*.bin files)
983     - new POLY3.COEFFS (for the next release one should switch to a full
984       equation of state: JMD95P or MDJWF)
985     - fixed several errors and redundancies in the data file
986     - experiment uses looped cells
987     - added matlab directory with diagnostic scripts for plotting of output
988    
989    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
990     - read AIM physics parameters from a file (data.aimphys)
991     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
992    
993    checkpoint46j_post
994    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
995    o move wVel computation at the end of the time step, in S/R integr_continuity
996    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
997    o update timeave pkg for wVel diagnostic.
998    checkpoint46j_pre
999    
1000    checkpoint46i_post
1001    o Clean up AIM package (and keep the results unchanged):
1002      include CPP_OPTION and use IMPLICT NONE in all routines ;
1003      declare all the variables _RL ; use _d 0 for all numerical constants.
1004      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1005    
1006    checkpoint46h_post
1007    o cleaned up the use of rhoNil and rhoConst.
1008      - rhoNil should only appear in the LINEAR equation of state, everywhere
1009        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1010        and the dynamical equations are all divided by rhoConst
1011    o introduced new parameter rhoConstFresh, a reference density of fresh
1012      water, to remove the fresh water flux's dependence on rhoNil. The default
1013      value is 999.8 kg/m^3
1014    o cleanup up external_forcing.F and external_forcing_surf.F
1015      - can now be used by both OCEANIC and OCEANICP
1016    checkpoint46h_pre
1017    
1018     Added code to convert surface volume flux (fresh water) into
1019     a mass flux when using P coordinates in the ocean (OCEANICP).
1020     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1021    
1022    checkpoint46g_post
1023    o Include a new diagnostic variable phiHydLow for the ocean model
1024      - in z-coordinates, it is the bottom pressure anomaly
1025      - in p-coordinates, it is the sea surface elevation
1026      - in both cases, these variable have global drift, reflecting the mass
1027        drift in z-coordinates and the volume drift in p-coordinates
1028      - included time averaging for phiHydLow, be aware of the drift!
1029    o depth-dependent computation of Bo_surf for pressure coordinates
1030      in the ocean (buoyancyRelation='OCEANICP')
1031      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1032        Theta, Salinity, and Pressure in the parameter list. This routine is
1033        presently contained in find_rho.F. This routine does not give the
1034        correct density for 'POLY3', which would be a z-dependent reference
1035        density.
1036    o cleaned up find_rho
1037      - removed obsolete 'eqn' from the parameter list.
1038    o added two new verification experiments: gop and goz
1039      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1040    checkpoint46g_pre
1041    
1042    checkpoint46f_post
1043    o Enable tangent linear (forward mode) gradient checks:
1044      - extended active file handling to g_... files
1045      - added TANGENT_SIMULATION to theSimulationMode
1046      - extended grdchk package accordingly
1047    o added tangent linear setup in verification/carbon/code_ftl
1048    o added adjoint setup in verification/front_relax/code_ad
1049    
1050    checkpoint46e_post
1051    o Added new equation of state -> MDJWF
1052      - EOS of McDougall et al., 2002, JAOT, submitted
1053      - caveat: the equation of state is only valid for a smaller (more
1054        realistic?) range of values than JMD95P/Z and UNESCO
1055      - added masks to the calculation of pressure in store_pressure
1056      - added more check values for density in check_eos (ini_eos.F), some of
1057        the old check values are out of the range of the MDJWF-eos, so don't
1058        expect perfect matches for those
1059    checkpoint46e_pre
1060    
1061    checkpoint46d_post
1062    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1063      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1064      case of pressure coordinates. eosType='JMD95Z' in
1065      combination with buoyancyRelation='OCEANICP' now causes an error.
1066    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1067      in find_alpha/beta.
1068    checkpoint46d_pre
1069    
1070    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1071      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1072    
1073    checkpoint46c_post
1074    o Changes necessary for ocean in p-coordinates
1075     -  Added new buoyancy relation = 'OCEANICP'
1076     -  Added new parameters = gravitySign (this used to be contained inside
1077        the factor dRdZ which I added when we first switched to R coordinates).
1078     X GM/Redi is not compatible (yet)
1079     X bottom drag and no-slip need to be debugged.
1080    checkpoint46c_pre
1081    
1082    checkpoint46b_post
1083    o Added new equation of state -> JMD95Z and JMD95P
1084      - EOS of Jackett and McDougall, 1995, JAOT
1085      - moved all EOS parameters into EOS.h
1086      - new routines ini_eos.F, store_pressure.F
1087    o Added UNESCO EOS, but not recommended because it requires
1088      in-situ temperature (see JMD95)
1089    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1090      unesco.f to be used with POLY3
1091    checkpoint46b_pre
1092    
1093    checkpoint46a_post
1094    o Added (atmospheric) pressure loading
1095      - new field in FFIELDS.h, etc...
1096      - new cpp flag ATMOSPHERIC_LOADING
1097    o Changed hFacC to _hFacC in calc_phi_hyd.F
1098    o Added SHORTWAVE_HEATING to some files for consistency
1099    checkpoint46a_pre
1100    
1101    checkpoint46
1102    further merges from release1_p5
1103    o new ctrl package
1104      - adopted from ECCO environment to enable optimization
1105      - added Eliassen Palm fluxes to controls

1107    o cost package
1108      - Compatible with new ctrl package
1109      - added Eliassen Palm cost hooks
1110      - modif's of existing cost functions
1111    o Adjoint-related bug fixes in kpp:
1112      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1113      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1114    o autodiff package
1115      - flow directives:
1116        + new for S/R do_the_model_io
1117        + enhanced for S/R checkpoint
1118        + new gmredi.flow

1120        disable adcommon.h/g_common.h by default.
1121      - fixed problem for adjoint of global_max
1122    o modified verification/carbon/
1123    o New setup for adjoint of global_ocean
1124    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1125    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1126    o incorporated hooks for sponge layer code (external_forcing.F)
1127    
1128    checkpoint45d_post
1129    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1130  o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S  o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1131    (affects plume_on_slope "cg2d" output)    (affects plume_on_slope "cg2d" output)
