124      + Not implemented so far:
125        - KPP
126        - OBCS
127      + No specific example supplied (yet) but global_ocean.90x40x15 has the
128        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
129        line in data.pkg.
130      + This package is disabled by default since it increases storage.
131    
132    
133    o testscript: added -cleanup option

148    o in genmake added variable MAKEDEPEND
149      plus resetting for case SunOS
150    o added timer_stats.c routine for IBM SP3
151    o removed variables in dynamics

154    
155    o real fresh water flux implemented with non-linear free-surface.
156    
157    chkpt44c_pre,post
158    o few fix (mask in shap_s2, EmPmR in external_field_load,
159      USE_NATURAL_BCS in solve_for_P);
160    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
161    
162    checkpoint44b_pre/_post

206    
207    checkpoint40
208    o moved calc_gs, calc_gt and calc_tr1 back to model/src
209    o added FLT (floats) package from Arne along with demo. experiment

225      
226    checkpoint40pre8
227    o new package rw/
228      Added method for dumping intermediate local arrays:
229      mdsio_writetile - same as mdsio_writefield except works from inside
230                        bi,bj loop
231      mdsio_writelocal - same as mdsio_writetile except works for local
232                         arrays
233      write_local_r? - higher-level wrapper for mdsio_writelocal
234      Controlled by diagFreq. Defaults to zero (ie. no dumps)
235      Example given at end of mom_vecinv.F that dumps some local arrays.
236    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
237      control flux-form versus vector invariant code.
238      Switch is runtime flag vectorInvariantMomentum (defaults to false)
239      or genmake -DISABLE ...
240    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
241      (additional storing is now needed for case vecinv;
242      currently nothing implemented to switch this storing off
243      in case fluxform is used since no CPP flag available).
244    
245    checkpoint40pre7
246    o bug fix in dynamics.F

255      calc_diffusivity, calc_viscosity
256      (kpp_calc_diff, kpp_calc_visc).
257    o Added diffkr, kapgm to control variables
258    o bug fix in gmredi_slope_limit for ldd97
259    
260    checkpoint40pre5
261    o proper initialization of Adams-Bashforth time stepping
262      + uses forward step for very first step of model (iter=0)
263    o re-generated *all* output since almost all output is modified by this
264      change (sorry but we've been putting this one off for about 2 years)
265      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
266        *not* regenerated since they are already out of date and I don't
267        want to create the impression that they are suddenly working.
268    o removed KAP stuff for DEC's
269    o modified/added many .cvsignore files in */code and */input
270    o added new expt "solid-body.cs-32x32x1"
271      + this uses an alternative form of ini_curvilinear_grid.F which
272        is not necessarily any better than the current one...
273    
274    checkpoint40pre4
275    o added re-initialisations of utrans,vtrans,rtrans in
276      calc_common_factors which are crucial for TAF.

301       cal: calendar
302       exf: external forcing
303       ecco: essential routines to control use of cal, exf
304             (NB: this is not the full ECCO environment)
305     o disabled some packages by default in genmake
306    
307    checkpoint38
308     o see notes_c37_adj.txt

312       (replaced criteria for initial/final state)
313     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
314    
315    checkpoint37
316     o mdsio.F routine split and packaged in pkg/mdsio
317       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
318        used unless genmake -disable=mdsio)
319     o allow a more precise surface-geopotential gradient for the atmosphere
320       taking into account the change in space of Alpha (=1/rho) at the surface.
321     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
322       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
323     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
324       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
325       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
326     o Time-Average diagnostics defined as a pseudo package "timeave".
327     o pickup files : old pickup (before c35) did not work with new code (c35
328       and after) unless activating 2 commented lines in initialise-varia.
329     o Non-Hydrostatic pickup file Pb fixed.
330     o bug with Rigid-lid version (since c35) fixed.  
331    
332    checkpoint36
333     o implement Crank-Nickelson barotropic time-stepping
334     o recover Time-Average diagnostics
335     o fix Pb in checkpoint (PR#19)
336     o AIM become a standard package ; clean unused CPP_kees
337    
338    checkpoint35
339     o subtantial rewrite of dynamics.f
340     o allows staggered time-stepping
341     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
342     o added bottom drag (linear + quadratic)
343    
344    checkpoint34
345     o Modified exchange routines for correct reverse simulation.
346     o Added verification output to comply with bug fix in impldiff.F
347       as of c33 (exp2, natl_box).
348     o Corrected store directives in dynamics.F
349     o Corrected array boundaries in impldiff.F
350     o Corrected array dimensions in gmredi.
351       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
352     o Added routine GLOBAL_SUM_INT to global_sum.F
353     o Added mdsio_gl.F for ECCO purposes.
354    
355    checkpoint33
356     o Fixed bug in lower BC in impldiff.F
357     o Fixed confusion about units of forcing arrays in FFIELDS.h
358       namely Fu,Fv,Qnet,Qsw,EmPmR:
359       - Removed verification/natl_box/code/external_fields_scale.F
360         (did not differ from that in model/src)
361       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
362         (see FFIELDS.h for description)
363       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
364         kpp_calc.F and kpp_transport_t.F
365       - Removed model/src/external_fields_scale.F and calls to it
366       - verification/natl_box uses flux data with "atmospheric" sign so
367         a special version of external_fields_load.F is used to
368         change the data as it's read in. This way, the arrays
369         have the right units and signs at all times tha a user could
370         possibly use them.
371     o Corrected genmake to delete a temporary file during configuration
372    
373    checkpoint32
374     o Scaling of forcing fields moved from external_forcing.F to
375       external_fields_scale.F, called directly after loading fields.
376     o Surface relaxation terms added to surface tendency fields in
377       extra subroutine.
378     o impldiff.F changed to avoid storing by TAMC of huge intermediate
379       fields.
380     o Changes in GMRedi to comply with packaging structure.
381     o Modifications and bug fixes in KPP package.
382     o Verification experiment for KPP added (verification/nat_box/)

384    checkpoint31
385     o Packages interface brought in line with defined standard
386       -> new routines packages_...F
387       -> changes in initialise_fixed.F, initialise_varia.F
388       -> enables initialisation interface for ECCO package
389     o Rescaling of external forcing fields immediately after read
390       (removed from external_forcing.F)
391       -> new: surface_fields_scale.F
392       -> affects ini_foorcing.F, external_fields_load.F
393     o Computation of surface tendencies before tendency updates.
394       -> new: external_forcing_surf.F
395     o Change of variable names useGMRedi, useKPP, useECCO
396     o Further changes in dynamics.F, impldiff.F for TAMC
397     o Tested for experiments 0, 2, 4.
398       - not yet tested for GMRedi.
399       - not yet tested for KPP.

416     o config_summary.F: replaced write_1D_... by write_0D_...
417       read_write.F: added subroutines write_0D_...
418     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
419       included some initialisations required for TAMC.
420     o routine calc_isoslopes: modified sqrt computation to make it
421       differentiable for zero argument.
422     o routines dynamics, impldiff:
423       included store directives and tape key computations required for TAMC.
424     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
425    
426    checkpoint27
427     o fixed calc_isoslopes() to so that cancellation of terms in tensor
428       formulation works properly with variable resolution.
429     o restructured the calling tree between the_model_main() and dynamics()
430     o split initialise() into initialise_fixed() and initialise_varia()

433    
434    checkpoint26
435     o moved some #ifdef in optional routines to encompass everything
436       except the argument declarations. This was using up some memory.
437     o fixed macros like _ADT to work with both versions of Linux cpp
438     o cleaned up some unused and uninitialized variables
439       (helps when debugging with strict compile options)
440     o split up CPP_EEOPTIONS.h into options and macros
441       (macros are now in eesupp/inc/CPP_EEMACROS.h)
442     o patch for 2 processor JAM mode
443    
444    checkpoint25
445     o updates for OBCs and NH
446     o dramatically reduced memory usage
447     o added "JAM" routines for use on Artic network
448     o parameterization of convection by implicit vertical diffusion
449     o added a diagnostic of convective index
450     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
451       (this is was partly for OBCs and NH but also in anticipation of
452        an explicit free-surface option)
453     o initial state input files for U and V
454    
455    checkpoint24
456     o Removed some spurious "REAL"s
457     o Updated KPP to latest version from JPL
458     o Added a COS(latitude) in horizontal viscosity
459    
460    checkpoint23
461     o Added del^4 diffusion for salt and temperature
462     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
463    
464    checkpoint22
465     o Made many small changes: implicit none, format(i5), etc...
466     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
467    
468    checkpoint21
469     o Introduced new I/O package that supports direct-access records (mdsio.F)
470     o Split-up mid-level I/O routines
471     o Updated input data for experiments 0,1,2,4 and 5
472     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
473    
474    checkpoint20
475     o Tidied up open-boundaries some more
476     o Added non-hydrostatic code
477     o Fixed some input data
478     o Modified MPI start-up to work in "coupled" context.
479    
480    checkpoint19
481     o Tidied up directory structure for verification experiments.
482     o Added new code for open boundaries.
483     o Corrected advective terms near boundaries.
484     o Added CPP flag for "old UV" geometry and corrected spherical geometry.
485     o Implemented free-slip/no-slip BCs and del^4 dissipation.
486     o Split default parameters out of ini_parms.F into set_defaults.F.
487    
488    checkpoint18
489     o Further changes for optional code generation with
490       CPP - ugh!
491    
492  checkpoint17  checkpoint17
493   o Beginning to incorporating modularity   o Beginning to incorporating modularity
494     for supporting atmos. and ocean configs.     for supporting atmos. and ocean configs.
