4      ==============================      ==============================
5    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
6    
7    checkpoint47i_post
8    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
9    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
10      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
11    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
12    o gmredi: fix few bugs.
13    
14    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
15    This will be a good checkpoint to plug into the ecco-branch.
16    o few modif.'s to get latest version adjointed
17      (mainly kick out code in ini_linear_phisurf)
18    o modif's to run adjoint with exactConserv
19    o case GM_BOLUS_ADVEC should be cleaned
20      S/R gmredi_slope_psi should be cleaned
21    o verification/carbon now has exactConserv=.TRUE.
22    
23    checkpoint47g_post
24    o time-average AIM output: becomes independent from statvars time-average
25      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
26    o After TAF bug fix:
27      Tested adjoint of gmredi package.
28      Tests were done with checkpoint47 rather than with latest
29      checkpoint47f_post since the latter is broken for the adjoint
30      verification/carbon/ contains both ADM and TLM gradient checks.
31    Here they are, before they get changed/lost/stolen.
32    Mostly modif.'s to fix numerical sensitivities.
33    Gradient checks OK for
34    - GM_taper_scheme:
35      * clipping
36      * ac02
37      * linear
38      * glw91
39      * dm95
40      * ldd97
41    - GMREDI_OPTIONS:
42      * GM_VISBECK_VARIABLE_K
43      * GM_NON_UNITY_DIAGONAL
44      * GM_EXTRA_DIAGONAL
45      * GM_BOLUS_ADVEC
46    in conjunction with data.gmredi parameters to be checked in
47    in a few minutes under verification/carbon/code/
48    
49    checkpoint47f_post
50    Merging from release1_p10:
51    o modifications for using pkg/exf with pkg/seaice
52      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
53        and SEAICE_EXTERNAL_FLUXES
54      - pkg/exf CPP options EXF_READ_EVAP and
55        EXF_NO_BULK_COMPUTATIONS
56      - usage examples are Experiments 8 and 9 in
57        verification/lab_sea/README
58      - verification/lab_sea default experiment now uses
59        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
60    
61    checkpoint47e_post
62    o created a tag prior to creating a branch
63    
64    checkpoint47d_post
65    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
66      at the bottom boundary had an erroneous half slip boundary condition
67    o added bottom drag and no slip boundary condition capabilities to
68      oceanic pressure coordinates code
69    o added new verification experiment global_ocean_pressure, this experiment is
70      also described in the tutorial section of the manual
71    checkpoint47d_pre
72    
73    checkpoint47c_post
74    o Added a verification experiment for a global cubed-sphere ocean run
75      -  verification/global_ocean.cubed32x32x30
76      -  uses pkg/therm_seaice and pkg/bulk_forcing
77    
78    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
79    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
80      when using P-coordinate; only implemented for atmospheric config.
81    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
82      NOTES: requires option NONLIN_FRSURF to be "#define".
83    o update advect_xz/results/output.txt (left from checkpoint44g_post)
84    
85    checkpoint47b_post
86    Merging from release1_p9:
87    o pkg/seaice
88      - removed GOTO's and added taf directives
89      - double precision constants to reduce the g77 (Linux)
90        to F77 (SGI) differences reported in release1_p8
91    o tools/genmake
92      - added SGI options
93    o verification/testscript
94      - updated to that of checkpoint47a_post
95    o verification/global_ocean.90x40x15/input/eedata
96      - modified for SGI f77 compatibility
97    o verification/lab_sea
98      - added description of sea-ice model
99      - added missing matlab routines
100      - added test of thermodynamics parallelization
101    
102    checkpoint47a_post
103    o new pkg: aim_v23
104     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
105       for now, keep the same surface forcing as before.
106     - Part-Cell implemented into AIM; check that Heat & Water are conserved
107     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
108     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
109    o add diagnostic of surface correction term in monitor output
110    
111    o bulk_force and therm_seaice
112    - Two packages:  bulk_force (Bulk forcing)
113      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
114    - Earlier integration from Stephaine Dutkiewicz
115      and Patrick Heimbach.
116    - Two ifdef statements for compile time,
117       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
118    
119    checkpoint47
120    differentiable version of checkpoint46n_post
121    o bug fix in quasihydrostaticterms
122    o * "clean" adjoint code (in terms of extensive recomputations)
123        can now be obtained for all GMREDI options (i.e. for
124        - GM_VISBECK_VARIABLE_K
125        - GM_NON_UNITY_DIAGONAL
126        - GM_EXTRA_DIAGONAL
127        - GM_BOLUS_ADVEC )
128      * However, wrong gradient check problem remains unsolved.
129      * New CPP options have been introduced for different
130        tapering schemes
131    o external_fields_load now part of differentiation list
132    o pressure needs multiple storing;
133      would be nice to have store_pressure at beginning or
134      end of forward_step, e.g. by having phiHyd global (5-dim.)
135      (NB: pressure is needed for certain cases in find_rho,
136      which is also invoked through convective_adjustment).
137    o recomputations in find_rho for cases
138     'JMD95'/'UNESCO' or 'MDJWF' are OK.
139    o #define ATMOSPHERIC_LOADING should be differentiable
140    o ini_forcing shifted to begining of initialise_varia
141    o Incorporating QNVS line search routines into MITgcm
142      (this is separate code, and therefore not under pkg)
143      lsopt/, optim/
144    o Updated verification/carbon/
145      - #define GM_VISBECK_VARIABLE_K
146      - GM_taper_scheme    = 'ldd97'    
147    
148    checkpoint46n_post
149    Merging from release1_p8:
150    o verification/natl_box:
151      updating new external_fields_load routine
152    o New package: pkg/seaice
153      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
154      The sea-ice code is based on Hibler (1979-1980).
155      Two sea-ice dynamic solvers, ADI and LSR, are included.
156      In addition to computing prognostic sea-ice variables and diagnosing
157      the forcing/external data fields that drive the ocean model,
158      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
159      The implied surface heat flux is then stored in variable
160      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
161      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
162      non-local transport term.  Because this call precedes model
163      thermodynamics, temperature under sea-ice may not be "exactly" at
164      the freezing point by the time theta is dumped or time-averaged.
165      N.B.: fairly large differences in accuracy occur across
166            different platforms/compilers; comparison between
167            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
168            generated output gives:
169       T           S           U           V
170      C D M    c        m  s        m  s        m  s        m  s
171      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
172      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
173      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
174    
175      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
176    o GAD:
177      - generated new common blocks to account for call of
178        same gad routines with differing traceridentities
179        (needed to modify tracerIdentity indices in GAD.h)
180      - generated separate common blocks for case useCubedSphereExchange
181        (Department of Futurology)
182      - parameter lists to gmredi_?transport: added tracerIdentity
183      - added new key indices to tamc.h
184    o external_fields_load:
185      - added this routine to TAF list
186      - needed to make some common blocks global and additional storing
187        along the same lines as exf package (checkpoint_lev?_directives.h)
188    o exf:
189      updated external forcing package
190      - bug fixes carried over from ecco-branch
191        (missing OBCS_OPTIONS.h in two routines)
192      - enable easy to use "no forcing".
193      - added exf I/O for atmospheric loading
194      - added exf I/O for runoff data
195      - transfered scaling between exf <-> MITgcm to exf namelist
196    o Adding new verification experiment global_with_exf.
197      This verification experiment is almost identical to the
198      global_ocean.90x40x15 experiment, except that it uses
199      the exf (and cal) package instead of the
200      external_fields_load routine (cf README file).
201    
202    checkpoint46m_post
203    o modified testscript to return -- when there are no lines of "%MON" output
204    o added new flag "quasiHydrostatic" for QH mode
205      and new routine quasihydrostaticterms()
206    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
207      New routine: mom_u_coriolis_nh()
208    o fixed sign of non-hydrostatic metric terms in u and v equations.
209      Depend on correct sign of gravitySign.
210    o added work.pc* to .cvsignore in aim directories using ifc
211    o introduced flag for controllin non-hydrostatic metric terms
212    o removed gravitySign from PARM04
213    o switched to g77/ifc from pgf77 in aim experiments
214    
215    checkpoint46l_post
216    o made convective adjustment work with pressure coordinates:
217     - changed the direction of k-loop in convective_adjustment.F for the
218       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
219     - adjusted the reference pressure k-index in convective_adjustment.F
220     - adjusted the convection condition in convect.F (in analogy to
221       calc_ivdc.F)
222     - convective_adjustment no longer computes anything on the halos
223     - removed the warnings about negative salinity from find_rho.F and
224       find_alpha.F; instead the new routine look_for_neg_salinity, called
225       at the beginning of find_rho, find_alpha, and find_beta, does a
226       check of the entire slice, if CPP-option
227       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
228    checkpoint46l_pre
229    
230    checkpoint46k_post
231    o fixed the verification/global_ocean.90x40x15 experiment:
232     - new bathymetry (the world according to A., JMC, and M.)
233     - new initial fields and forcing fields (*.bin files)
234     - new POLY3.COEFFS (for the next release one should switch to a full
235       equation of state: JMD95P or MDJWF)
236     - fixed several errors and redundancies in the data file
237     - experiment uses looped cells
238     - added matlab directory with diagnostic scripts for plotting of output
239    
240    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
241     - read AIM physics parameters from a file (data.aimphys)
242     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
243    
244    checkpoint46j_post
245    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
246    o move wVel computation at the end of the time step, in S/R integr_continuity
247    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
248    o update timeave pkg for wVel diagnostic.
249    checkpoint46j_pre
250    
251    checkpoint46i_post
252    o Clean up AIM package (and keep the results unchanged):
253      include CPP_OPTION and use IMPLICT NONE in all routines ;
254      declare all the variables _RL ; use _d 0 for all numerical constants.
255      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
256    
257    checkpoint46h_post
258    o cleaned up the use of rhoNil and rhoConst.
259      - rhoNil should only appear in the LINEAR equation of state, everywhere
260        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
261        and the dynamical equations are all divided by rhoConst
262    o introduced new parameter rhoConstFresh, a reference density of fresh
263      water, to remove the fresh water flux's dependence on rhoNil. The default
264      value is 999.8 kg/m^3
265    o cleanup up external_forcing.F and external_forcing_surf.F
266      - can now be used by both OCEANIC and OCEANICP
267    checkpoint46h_pre
268    
269     Added code to convert surface volume flux (fresh water) into
270     a mass flux when using P coordinates in the ocean (OCEANICP).
271     Note: It assumes you have set rho0=rhoConst=density of fresh water.
272    
273    checkpoint46g_post
274    o Include a new diagnostic variable phiHydLow for the ocean model
275      - in z-coordinates, it is the bottom pressure anomaly
276      - in p-coordinates, it is the sea surface elevation
277      - in both cases, these variable have global drift, reflecting the mass
278        drift in z-coordinates and the volume drift in p-coordinates
279      - included time averaging for phiHydLow, be aware of the drift!
280    o depth-dependent computation of Bo_surf for pressure coordinates
281      in the ocean (buoyancyRelation='OCEANICP')
282      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
283        Theta, Salinity, and Pressure in the parameter list. This routine is
284        presently contained in find_rho.F. This routine does not give the
285        correct density for 'POLY3', which would be a z-dependent reference
286        density.
287    o cleaned up find_rho
288      - removed obsolete 'eqn' from the parameter list.
289    o added two new verification experiments: gop and goz
290      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
291    checkpoint46g_pre
292    
293    checkpoint46f_post
294    o Enable tangent linear (forward mode) gradient checks:
295      - extended active file handling to g_... files
296      - added TANGENT_SIMULATION to theSimulationMode
297      - extended grdchk package accordingly
298    o added tangent linear setup in verification/carbon/code_ftl
299    o added adjoint setup in verification/front_relax/code_ad
300    
301    checkpoint46e_post
302    o Added new equation of state -> MDJWF
303      - EOS of McDougall et al., 2002, JAOT, submitted
304      - caveat: the equation of state is only valid for a smaller (more
305        realistic?) range of values than JMD95P/Z and UNESCO
306      - added masks to the calculation of pressure in store_pressure
307      - added more check values for density in check_eos (ini_eos.F), some of
308        the old check values are out of the range of the MDJWF-eos, so don't
309        expect perfect matches for those
310    checkpoint46e_pre
311    
312    checkpoint46d_post
313    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
314      'OCEANICP', also initialised field pressure correctly in ini_eos in the
315      case of pressure coordinates. eosType='JMD95Z' in
316      combination with buoyancyRelation='OCEANICP' now causes an error.
317    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
318      in find_alpha/beta.
319    checkpoint46d_pre
320    
321    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
322      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
323    
324    checkpoint46c_post
325    o Changes necessary for ocean in p-coordinates
326     -  Added new buoyancy relation = 'OCEANICP'
327     -  Added new parameters = gravitySign (this used to be contained inside
328        the factor dRdZ which I added when we first switched to R coordinates).
329     X GM/Redi is not compatible (yet)
330     X bottom drag and no-slip need to be debugged.
331    checkpoint46c_pre
332    
333    checkpoint46b_post
334    o Added new equation of state -> JMD95Z and JMD95P
335      - EOS of Jackett and McDougall, 1995, JAOT
336      - moved all EOS parameters into EOS.h
337      - new routines ini_eos.F, store_pressure.F
338    o Added UNESCO EOS, but not recommended because it requires
339      in-situ temperature (see JMD95)
340    o Modified formatting for knudsen2.f in utils/knudsen2 and added
341      unesco.f to be used with POLY3
342    checkpoint46b_pre
343    
344    checkpoint46a_post
345    o Added (atmospheric) pressure loading
346      - new field in FFIELDS.h, etc...
347      - new cpp flag ATMOSPHERIC_LOADING
348    o Changed hFacC to _hFacC in calc_phi_hyd.F
349    o Added SHORTWAVE_HEATING to some files for consistency
350    checkpoint46a_pre
351    
352    checkpoint46
353    further merges from release1_p5
354    o new ctrl package
355      - adopted from ECCO environment to enable optimization
356      - added Eliassen Palm fluxes to controls
357    o added Eliassen Palm flux controls to gradient check package
358    o cost package
359      - Compatible with new ctrl package
360      - added Eliassen Palm cost hooks
361      - modif's of existing cost functions
362    o Adjoint-related bug fixes in kpp:
363      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
364      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
365    o autodiff package
366      - flow directives:
367        + new for S/R do_the_model_io
368        + enhanced for S/R checkpoint
369        + new gmredi.flow
370      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
371        disable adcommon.h/g_common.h by default.
372      - fixed problem for adjoint of global_max
373    o modified verification/carbon/
374    o New setup for adjoint of global_ocean
375    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
376    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
377    o incorporated hooks for sponge layer code (external_forcing.F)
378    
379    checkpoint45d_post
380    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
381    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
382      (affects plume_on_slope "cg2d" output)
383    o add new parameter deltaTfreesurf for free-surface time stepping
384    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
385    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
386    o change phiMin in exp1 (to agree with documentation)
387    o add new flags:
388     - T,S forcing inside/outside Adams-Bashforth
389     - turn off temp,salt advection and/or forcing
390     - for each tracer, define internal flag for multiDimAdvection & A-B
391    o monitor: change definition of KE to check conservation of Energy
392    
393    checkpoint45c_post
394    o Removed f90 comments ("!")
395    o Modified initialisations to enable exf package for MITgcm
396      (without invoking ECCO_PACKAGE).
397    o modifications to gradient check package (Martin Losch)
398      - enable centered differences
399      - modified format of standard output
400    
401    checkpoint45b_post
402    o cleaned exchange calls in cg2d
403    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
404    o included CPP option SINGLE_LAYER_MODE in thermodynamics
405      to configure barotropic setup (Martin Losch)
406    o moved some initialisations within bi,bj loop in dynamics
407      (TAF flow dependency)
408    o in initialise_varia, moved call packages_init_variables
409      before convective_adjustment_init
410      (corresponding adjustment of TAF tape initialisation).
411    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
412    
413    checkpoint45a_post

418    
419    checkpoint44h_post = checkpoint45
420    o Fix to restore differentiability:
421      place at which packages_init_variables is called in
422      initialise_varia is crucial for reverse control flow.

424      (corresponding modif's in thermodynamics, dynamics)
425    o added missing hook for sponge layer code in external_forcing

447      + Implemented so far:
448        - basic forward algorithm (time-stepping, advection, diffusion, convection)
449        - I/O and checkpointing
450        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
451      + Not implemented so far:
452        - KPP
453        - OBCS
454      + No specific example supplied (yet) but global_ocean.90x40x15 has the
455        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
456        line in data.pkg.
457      + This package is disabled by default since it increases storage.
458    
459    
460    o testscript: added -cleanup option
461    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter

463    
464    checkpoint44e_pre,post
465    o re-wrote convective adjustment to use pre-calculated weights
466      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
467      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
468      Original calls to convect() still in place.
469    
470    chkpt44d_pre,post
471    o added missing EXCLUDE_MONITOR flags
472    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
473      (incompatible typ in MIN/MAX expressions caused problems
474      on IBM SP3)
475    o in genmake added variable MAKEDEPEND
476      plus resetting for case SunOS
477    o added timer_stats.c routine for IBM SP3
478    o removed variables in dynamics
479    !!! I forgot to create tag chkpt44d_pre !!!
480    !!! But chkpt44d_pre = chkpt44c_post    !!!
481    
482    o real fresh water flux implemented with non-linear free-surface.
483    
484    chkpt44c_pre,post
485    o few fix (mask in shap_s2, EmPmR in external_field_load,
486      USE_NATURAL_BCS in solve_for_P);
487    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
488    
489    checkpoint44b_pre/_post

520    o Store directives up-to-date with re-arranged Adams-Bashforth
521      (mainly thermodynamics.F)
522    o New store directives for multi-dim. advection schemes
523      * new CPP flag ALLOW_MULTI_DIM_ADVECTION

527      for the case ALLOW_KPP
528    o Cleaned argument list for timestep_tracer.F
529    
530    checkpoint41
531    o re-formatted/added comments in prologues of key subroutines
532      to work with protex
533    
534    checkpoint40
535    o moved calc_gs, calc_gt and calc_tr1 back to model/src
536    o added FLT (floats) package from Arne along with demo. experiment
537    o re-arranged Adams-Bashforth scheme for tracers to allow easier

555      Added method for dumping intermediate local arrays:
556      mdsio_writetile - same as mdsio_writefield except works from inside
557                        bi,bj loop
558      mdsio_writelocal - same as mdsio_writetile except works for local
559                         arrays
560      write_local_r? - higher-level wrapper for mdsio_writelocal
561      Controlled by diagFreq. Defaults to zero (ie. no dumps)
562      Example given at end of mom_vecinv.F that dumps some local arrays.
563    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
564      control flux-form versus vector invariant code.
565      Switch is runtime flag vectorInvariantMomentum (defaults to false)
566      or genmake -DISABLE ...
567    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
568      (additional storing is now needed for case vecinv;
569      currently nothing implemented to switch this storing off
570      in case fluxform is used since no CPP flag available).
571    
572    checkpoint40pre7
573    o bug fix in dynamics.F

581    o corresponding split of calc_diffusivity into
582      calc_diffusivity, calc_viscosity
583      (kpp_calc_diff, kpp_calc_visc).
584    o Added diffkr, kapgm to control variables
585    o bug fix in gmredi_slope_limit for ldd97
586    
587    checkpoint40pre5
588    o proper initialization of Adams-Bashforth time stepping
589      + uses forward step for very first step of model (iter=0)
590    o re-generated *all* output since almost all output is modified by this
591      change (sorry but we've been putting this one off for about 2 years)
592      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
593        *not* regenerated since they are already out of date and I don't
594        want to create the impression that they are suddenly working.
595    o removed KAP stuff for DEC's
596    o modified/added many .cvsignore files in */code and */input
597    o added new expt "solid-body.cs-32x32x1"
598      + this uses an alternative form of ini_curvilinear_grid.F which
599        is not necessarily any better than the current one...
600    
601    checkpoint40pre4
602    o added re-initialisations of utrans,vtrans,rtrans in
603      calc_common_factors which are crucial for TAF.
604    o extended iMin,jMin range for calc_common_factors,
605      calc_diffusivity

618    o Added carbon sequestration sensitivity experiment
619    
620    checkpoint39
621     o Modifications and fixes to support TAMC

626     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
627     o Included following packages:
628       cal: calendar
629       exf: external forcing
630       ecco: essential routines to control use of cal, exf
631             (NB: this is not the full ECCO environment)
632     o disabled some packages by default in genmake
633    
634    checkpoint38
635     o see notes_c37_adj.txt

640     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
641    
642    checkpoint37
643     o mdsio.F routine split and packaged in pkg/mdsio
644       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
645        used unless genmake -disable=mdsio)
646     o allow a more precise surface-geopotential gradient for the atmosphere
647       taking into account the change in space of Alpha (=1/rho) at the surface.
648     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
649       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
650     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
651       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
652       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
653     o Time-Average diagnostics defined as a pseudo package "timeave".
654     o pickup files : old pickup (before c35) did not work with new code (c35
655       and after) unless activating 2 commented lines in initialise-varia.
656     o Non-Hydrostatic pickup file Pb fixed.
657     o bug with Rigid-lid version (since c35) fixed.  
658    
659    checkpoint36
660     o implement Crank-Nickelson barotropic time-stepping
661     o recover Time-Average diagnostics
662     o fix Pb in checkpoint (PR#19)
663     o AIM become a standard package ; clean unused CPP_kees
664    
665    checkpoint35
666     o subtantial rewrite of dynamics.f
667     o allows staggered time-stepping
668     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
669     o added bottom drag (linear + quadratic)
670    
671    checkpoint34
672     o Modified exchange routines for correct reverse simulation.
673     o Added verification output to comply with bug fix in impldiff.F
674       as of c33 (exp2, natl_box).
675     o Corrected store directives in dynamics.F
676     o Corrected array boundaries in impldiff.F
677     o Corrected array dimensions in gmredi.
678       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
679     o Added routine GLOBAL_SUM_INT to global_sum.F
680     o Added mdsio_gl.F for ECCO purposes.
681    
682    checkpoint33
683     o Fixed bug in lower BC in impldiff.F
684     o Fixed confusion about units of forcing arrays in FFIELDS.h
685       namely Fu,Fv,Qnet,Qsw,EmPmR:
686       - Removed verification/natl_box/code/external_fields_scale.F
687         (did not differ from that in model/src)
688       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
689         (see FFIELDS.h for description)
690       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
691         kpp_calc.F and kpp_transport_t.F
692       - Removed model/src/external_fields_scale.F and calls to it
693       - verification/natl_box uses flux data with "atmospheric" sign so
694         a special version of external_fields_load.F is used to
695         change the data as it's read in. This way, the arrays
696         have the right units and signs at all times tha a user could
697         possibly use them.
698     o Corrected genmake to delete a temporary file during configuration
699    
700    checkpoint32
701     o Scaling of forcing fields moved from external_forcing.F to
702       external_fields_scale.F, called directly after loading fields.
703     o Surface relaxation terms added to surface tendency fields in
704       extra subroutine.

706       fields.
707     o Changes in GMRedi to comply with packaging structure.
708     o Modifications and bug fixes in KPP package.
709     o Verification experiment for KPP added (verification/nat_box/)

713       -> new routines packages_...F
714       -> changes in initialise_fixed.F, initialise_varia.F
715       -> enables initialisation interface for ECCO package
716     o Rescaling of external forcing fields immediately after read
717       (removed from external_forcing.F)
718       -> new: surface_fields_scale.F
719       -> affects ini_foorcing.F, external_fields_load.F
720     o Computation of surface tendencies before tendency updates.
721       -> new: external_forcing_surf.F
722     o Change of variable names useGMRedi, useKPP, useECCO
723     o Further changes in dynamics.F, impldiff.F for TAMC
724     o Tested for experiments 0, 2, 4.
725       - not yet tested for GMRedi.
726       - not yet tested for KPP.
727    
728    checkpoint30

742     o Modified calculation of partial cell thickness to more robust algorithm
743     o config_summary.F: replaced write_1D_... by write_0D_...
744       read_write.F: added subroutines write_0D_...
745     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
746       included some initialisations required for TAMC.
747     o routine calc_isoslopes: modified sqrt computation to make it
748       differentiable for zero argument.
749     o routines dynamics, impldiff:
750       included store directives and tape key computations required for TAMC.
751     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
752    
753    checkpoint27
754     o fixed calc_isoslopes() to so that cancellation of terms in tensor
755       formulation works properly with variable resolution.
756     o restructured the calling tree between the_model_main() and dynamics()
757     o split initialise() into initialise_fixed() and initialise_varia()

759       in new routine ini_psurf()
760    
761    checkpoint26
762     o moved some #ifdef in optional routines to encompass everything
763       except the argument declarations. This was using up some memory.
764     o fixed macros like _ADT to work with both versions of Linux cpp
765     o cleaned up some unused and uninitialized variables
766       (helps when debugging with strict compile options)
767     o split up CPP_EEOPTIONS.h into options and macros
768       (macros are now in eesupp/inc/CPP_EEMACROS.h)
769     o patch for 2 processor JAM mode
770    
771    checkpoint25
772     o updates for OBCs and NH
773     o dramatically reduced memory usage
774     o added "JAM" routines for use on Artic network
775     o parameterization of convection by implicit vertical diffusion
776     o added a diagnostic of convective index
777     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
778       (this is was partly for OBCs and NH but also in anticipation of
779        an explicit free-surface option)
780     o initial state input files for U and V
781    
782    checkpoint24
783     o Removed some spurious "REAL"s

790    
791    checkpoint22
792     o Made many small changes: implicit none, format(i5), etc...

794    
795    checkpoint21
796     o Introduced new I/O package that supports direct-access records (mdsio.F)
797     o Split-up mid-level I/O routines
798     o Updated input data for experiments 0,1,2,4 and 5

800    
801    checkpoint20
802     o Tidied up open-boundaries some more
803     o Added non-hydrostatic code

817       CPP - ugh!
818    
819    checkpoint17
820     o Beginning to incorporating modularity
821       for supporting atmos. and ocean configs.
822     o Small changes for TAMC complinace
823     o New ultra simple test case. Barotropic box
824       configuration "exp0".
825    
826    checkpoint16
827     o Minor changes to exchange routines to support
828       accumulation in reverse mode. Adjoint of an
829       assignment is an addition.
830     o Changes to support compilation by TAMC (LR(1)
831       syntax) and by g77 under Linux ( 72 character
832       limit ).
833    
834    checkpoint15
835     Rewrote exchange routines to allow
836     o General tile <-> tile connectivity.
837     o TAMC reverse mode flag ( is this really needed? )
838     o Variable width overlap and exchange region widths.
839     o Hooks for sharing data via DMA, Arctic, Memory Channel,
840       shmput/shmget, VIA, SYSV shmem and every other cool
841       communication method.
842    
843    checkpoint14
844     Consistent isomorphism chages made. These allow dynamical core
845     to support both pressure and meters as a vertical coordinate.
846    
847    checkpoint13
848     Release which corrects global_max problem and a couple
849     of KGM time-averaging diagnostic errors. Also contains
850     a double-gyre experiment setup as well as the baseline
851     4 degree global template. The double gyre template is
852     organised to allow it to be applied automatically to
853     the baseline configuration.
854    
855    branch-point-rdot
856     A few tidy-ups have been made bt the real point of this
857     check-point (excuse the pun) is to allow a branch to be
858     made for the purposes of adding the rDot alterations.
859     I don't want to commit the rDot to the main-trunk until
860     we've actually tested it...
