7    o modifications to gradient check package (Martin Losch)
8      - enable centered differences
9      - modified format of standard output
10    o bug fix for nwettile contents
11      so far assumed global sum  in first entry (1,1,k),
12      needed for global control vector
13      -> introduced new variable nwet[c/w/s]global(nr)
14    o shifts of calls to cal/exf package to be accessible
15      in MITgcm stand-alone
16    o shifted packages_init_variables before convective_adjustment_ini
17      (corresponding update of TAF tape initialisation).

19      (caused numerical differences for GMRedi cases)
20    o updated obcs control part (G. Gebbie)
21    o removed some f90 comments ("!")
22    o Bug fixes and updates in cost package
23     * cost_final: correct multiplier mult_tauv, mult_sflux

30    ecco_c44_e23
31    merged patches between release1_p1 and release1_p2:
32    o fixed array boundary problem for adjoint
33      (related to partial recomputation within subroutine
34      related to dynamics -> calc_viscosity -> mom_...

40    
41    ecco_c44_e22
42    o Finally, the merges with the Scripps cost function terms:
43      Various additions, modifications, quality checks.
44    o Plus: Included switch ALLOW_AUTODIFF_MONITOR to handle
45      monitoring of adjoint state.
46    o Plus: removed comm_stats, ini_communication_patterns from diff. list
47      (no more need to "keep" MPI headers for adjoint generation)
48    o Plus: exf changes:
49      o added run-off routine
50      o additional storing needed for ustress,vstess
51        because of state-dependent quality check
52      o added missing initialisations
53    o Plus: genmake with MAKEDEPEND variable was still missing in ecco-branch
54    NB: - verification/natl_box_adjoint/ 240 steps run
55          * looks ok under Linux (twain.lcs.mit.edu)
56          * looks ok on MIT SUN's (fjord.mit.edu)
57          * NaN in reverse mode on Scripps SUN's at iter=214

128    o last changes:
129      * assuming path for TAF and TAMC are known (e.g. in $path)
130      * genmake:
131        - added tools/xmakedepend to circumvene shortcoming of
132          SUN's makedepend (size too small)

161      This set of changes is relevant for ECCO only.
162      The next set/tag of changes (ecco-branch-mod4)
163      should be merged into the main trunk.
164      - update some options

235      mdsio_writetile - same as mdsio_writefield except works from inside
236                        bi,bj loop
237      mdsio_writelocal - same as mdsio_writetile except works for local
238                         arrays
239      write_local_r? - higher-level wrapper for mdsio_writelocal
240      Controlled by diagFreq. Defaults to zero (ie. no dumps)
241      Example given at end of mom_vecinv.F that dumps some local arrays.
242    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to

244      Switch is runtime flag vectorInvariantMomentum (defaults to false)
245      or genmake -DISABLE ...
246    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
247      (additional storing is now needed for case vecinv;
248      currently nothing implemented to switch this storing off
249      in case fluxform is used since no CPP flag available).
250

263    o Added diffkr, kapgm to control variables
264    o bug fix in gmredi_slope_limit for ldd97
265    
266    checkpoint40pre5
267    o proper initialization of Adams-Bashforth time stepping
268      + uses forward step for very first step of model (iter=0)
269    o re-generated *all* output since almost all output is modified by this
270      change (sorry but we've been putting this one off for about 2 years)
271      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
272        *not* regenerated since they are already out of date and I don't
273        want to create the impression that they are suddenly working.
274    o removed KAP stuff for DEC's
275    o modified/added many .cvsignore files in */code and */input
276    o added new expt "solid-body.cs-32x32x1"
277      + this uses an alternative form of ini_curvilinear_grid.F which
278        is not necessarily any better than the current one...
279    
280    checkpoint40pre4
281    o added re-initialisations of utrans,vtrans,rtrans in
282      calc_common_factors which are crucial for TAF.

297    o Added carbon sequestration sensitivity experiment
298    
299    checkpoint39
300     o Modifications and fixes to support TAMC

307       cal: calendar
308       exf: external forcing
309       ecco: essential routines to control use of cal, exf
310             (NB: this is not the full ECCO environment)
311     o disabled some packages by default in genmake
312    
313    checkpoint38

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

392       -> new routines packages_...F
393       -> changes in initialise_fixed.F, initialise_varia.F
394       -> enables initialisation interface for ECCO package
395     o Rescaling of external forcing fields immediately after read
396       (removed from external_forcing.F)
397       -> new: surface_fields_scale.F
398       -> affects ini_foorcing.F, external_fields_load.F
399     o Computation of surface tendencies before tendency updates.
400       -> new: external_forcing_surf.F
401     o Change of variable names useGMRedi, useKPP, useECCO
402     o Further changes in dynamics.F, impldiff.F for TAMC
403     o Tested for experiments 0, 2, 4.
404       - not yet tested for GMRedi.
405       - not yet tested for KPP.
406    
407    checkpoint30
408     o Updates for OBCs
409     o New experiment for test OBCs (internal_wave)

422     o config_summary.F: replaced write_1D_... by write_0D_...
423       read_write.F: added subroutines write_0D_...
424     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
425       included some initialisations required for TAMC.
426     o routine calc_isoslopes: modified sqrt computation to make it
427       differentiable for zero argument.
428     o routines dynamics, impldiff:
429       included store directives and tape key computations required for TAMC.
430     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
431    
432    checkpoint27
433     o fixed calc_isoslopes() to so that cancellation of terms in tensor
434       formulation works properly with variable resolution.
435     o restructured the calling tree between the_model_main() and dynamics()
436     o split initialise() into initialise_fixed() and initialise_varia()
437     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
438       in new routine ini_psurf()

440    checkpoint26
441     o moved some #ifdef in optional routines to encompass everything
442       except the argument declarations. This was using up some memory.
443     o fixed macros like _ADT to work with both versions of Linux cpp
444     o cleaned up some unused and uninitialized variables
445       (helps when debugging with strict compile options)
446     o split up CPP_EEOPTIONS.h into options and macros
447       (macros are now in eesupp/inc/CPP_EEMACROS.h)
448     o patch for 2 processor JAM mode
449    
450    checkpoint25
451     o updates for OBCs and NH
452     o dramatically reduced memory usage
453     o added "JAM" routines for use on Artic network
454     o parameterization of convection by implicit vertical diffusion
455     o added a diagnostic of convective index
456     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
457       (this is was partly for OBCs and NH but also in anticipation of
458        an explicit free-surface option)
459     o initial state input files for U and V
460    
461    checkpoint24
462     o Removed some spurious "REAL"s
463     o Updated KPP to latest version from JPL
464     o Added a COS(latitude) in horizontal viscosity
465    
466    checkpoint23
467     o Added del^4 diffusion for salt and temperature
468     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
469    
470    checkpoint22
471     o Made many small changes: implicit none, format(i5), etc...
472     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
473    
474    checkpoint21
475     o Introduced new I/O package that supports direct-access records (mdsio.F)
476     o Split-up mid-level I/O routines
477     o Updated input data for experiments 0,1,2,4 and 5
478     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
479    
480    checkpoint20
481     o Tidied up open-boundaries some more
482     o Added non-hydrostatic code
483     o Fixed some input data
484     o Modified MPI start-up to work in "coupled" context.
485    
486    checkpoint19
487     o Tidied up directory structure for verification experiments.
488     o Added new code for open boundaries.
489     o Corrected advective terms near boundaries.
490     o Added CPP flag for "old UV" geometry and corrected spherical geometry.
491     o Implemented free-slip/no-slip BCs and del^4 dissipation.
492     o Split default parameters out of ini_parms.F into set_defaults.F.
493    
494    checkpoint18
495     o Further changes for optional code generation with
496       CPP - ugh!
497    
498    checkpoint17
499     o Beginning to incorporating modularity
500       for supporting atmos. and ocean configs.
501     o Small changes for TAMC complinace
502     o New ultra simple test case. Barotropic box
503       configuration "exp0".
