106    checkpoint40pre8
107    o new package rw/
108      Added method for dumping intermediate local arrays:
109      mdsio_writetile - same as mdsio_writefield except works from inside
110                        bi,bj loop
111      mdsio_writelocal - same as mdsio_writetile except works for local
112                         arrays
113      write_local_r? - higher-level wrapper for mdsio_writelocal
114      Controlled by diagFreq. Defaults to zero (ie. no dumps)
115      Example given at end of mom_vecinv.F that dumps some local arrays.
116    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to

119      or genmake -DISABLE ...
120    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
121      (additional storing is now needed for case vecinv;
122      currently nothing implemented to switch this storing off

124    
125    checkpoint40pre7
126    o bug fix in dynamics.F
127      calc_viscosity called before k=1,Nr loop.

134    o corresponding split of calc_diffusivity into
135      calc_diffusivity, calc_viscosity
136      (kpp_calc_diff, kpp_calc_visc).
137    o Added diffkr, kapgm to control variables
138    o bug fix in gmredi_slope_limit for ldd97
139    
140    checkpoint40pre5
141    o proper initialization of Adams-Bashforth time stepping
142      + uses forward step for very first step of model (iter=0)
143    o re-generated *all* output since almost all output is modified by this
144      change (sorry but we've been putting this one off for about 2 years)
145      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
146        *not* regenerated since they are already out of date and I don't
147        want to create the impression that they are suddenly working.
148    o removed KAP stuff for DEC's
149    o modified/added many .cvsignore files in */code and */input
150    o added new expt "solid-body.cs-32x32x1"
151      + this uses an alternative form of ini_curvilinear_grid.F which
152        is not necessarily any better than the current one...
153    
154    checkpoint40pre4
155    o added re-initialisations of utrans,vtrans,rtrans in
156      calc_common_factors which are crucial for TAF.

169    o Added gradient check package
170    o Added routines for passive tracer handling
171    o Added carbon sequestration sensitivity experiment
172    
173    checkpoint39
174     o Modifications and fixes to support TAMC
175       (mainly missing or wrong directives)

177       in addummy_in_stepping
178     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
179     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
180     o Included following packages:
181       cal: calendar
182       exf: external forcing
183       ecco: essential routines to control use of cal, exf
184             (NB: this is not the full ECCO environment)
185     o disabled some packages by default in genmake
186    
187    checkpoint38
188     o see notes_c37_adj.txt

193     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
194    
195    checkpoint37
196     o mdsio.F routine split and packaged in pkg/mdsio
197       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
198        used unless genmake -disable=mdsio)
199     o allow a more precise surface-geopotential gradient for the atmosphere
200       taking into account the change in space of Alpha (=1/rho) at the surface.
201     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
202       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
203     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
204       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
205       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
206     o Time-Average diagnostics defined as a pseudo package "timeave".
207     o pickup files : old pickup (before c35) did not work with new code (c35
208       and after) unless activating 2 commented lines in initialise-varia.
209     o Non-Hydrostatic pickup file Pb fixed.
210     o bug with Rigid-lid version (since c35) fixed.  
211    
212    checkpoint36
213     o implement Crank-Nickelson barotropic time-stepping
214     o recover Time-Average diagnostics
215     o fix Pb in checkpoint (PR#19)
216     o AIM become a standard package ; clean unused CPP_kees
217    
218    checkpoint35
219     o subtantial rewrite of dynamics.f
220     o allows staggered time-stepping
221     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
222     o added bottom drag (linear + quadratic)
223    
224    checkpoint34
225     o Modified exchange routines for correct reverse simulation.
226     o Added verification output to comply with bug fix in impldiff.F
227       as of c33 (exp2, natl_box).
228     o Corrected store directives in dynamics.F
229     o Corrected array boundaries in impldiff.F
230     o Corrected array dimensions in gmredi.
231       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
232     o Added routine GLOBAL_SUM_INT to global_sum.F
233     o Added mdsio_gl.F for ECCO purposes.
234    
235    checkpoint33
236     o Fixed bug in lower BC in impldiff.F
237     o Fixed confusion about units of forcing arrays in FFIELDS.h
238       namely Fu,Fv,Qnet,Qsw,EmPmR:
239       - Removed verification/natl_box/code/external_fields_scale.F
240         (did not differ from that in model/src)
241       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
242         (see FFIELDS.h for description)
243       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
244         kpp_calc.F and kpp_transport_t.F
245       - Removed model/src/external_fields_scale.F and calls to it
246       - verification/natl_box uses flux data with "atmospheric" sign so
247         a special version of external_fields_load.F is used to
248         change the data as it's read in. This way, the arrays
249         have the right units and signs at all times tha a user could
250         possibly use them.
251     o Corrected genmake to delete a temporary file during configuration
252    
253    checkpoint32
254     o Scaling of forcing fields moved from external_forcing.F to
255       external_fields_scale.F, called directly after loading fields.
256     o Surface relaxation terms added to surface tendency fields in
257       extra subroutine.
258     o impldiff.F changed to avoid storing by TAMC of huge intermediate
259       fields.
260     o Changes in GMRedi to comply with packaging structure.
261     o Modifications and bug fixes in KPP package.
262     o Verification experiment for KPP added (verification/nat_box/)
263    
264    checkpoint31
265     o Packages interface brought in line with defined standard
266       -> new routines packages_...F
267       -> changes in initialise_fixed.F, initialise_varia.F
268       -> enables initialisation interface for ECCO package
269     o Rescaling of external forcing fields immediately after read
270       (removed from external_forcing.F)
271       -> new: surface_fields_scale.F
272       -> affects ini_foorcing.F, external_fields_load.F
273     o Computation of surface tendencies before tendency updates.
274       -> new: external_forcing_surf.F
275     o Change of variable names useGMRedi, useKPP, useECCO
276     o Further changes in dynamics.F, impldiff.F for TAMC
277     o Tested for experiments 0, 2, 4.
278       - not yet tested for GMRedi.
279       - not yet tested for KPP.
280    
281    checkpoint30

295     o Modified calculation of partial cell thickness to more robust algorithm
296     o config_summary.F: replaced write_1D_... by write_0D_...
297       read_write.F: added subroutines write_0D_...
298     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
299       included some initialisations required for TAMC.
300     o routine calc_isoslopes: modified sqrt computation to make it
301       differentiable for zero argument.
302     o routines dynamics, impldiff:
303       included store directives and tape key computations required for TAMC.
304     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
305    
306    checkpoint27
307     o fixed calc_isoslopes() to so that cancellation of terms in tensor
308       formulation works properly with variable resolution.
309     o restructured the calling tree between the_model_main() and dynamics()
310     o split initialise() into initialise_fixed() and initialise_varia()

313    
314    checkpoint26

316       except the argument declarations. This was using up some memory.
317     o fixed macros like _ADT to work with both versions of Linux cpp
318     o cleaned up some unused and uninitialized variables
319       (helps when debugging with strict compile options)
320     o split up CPP_EEOPTIONS.h into options and macros
321       (macros are now in eesupp/inc/CPP_EEMACROS.h)
322     o patch for 2 processor JAM mode
323    
324    checkpoint25
325     o updates for OBCs and NH
326     o dramatically reduced memory usage
327     o added "JAM" routines for use on Artic network
328     o parameterization of convection by implicit vertical diffusion
329     o added a diagnostic of convective index
330     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
331       (this is was partly for OBCs and NH but also in anticipation of
332        an explicit free-surface option)

381       accumulation in reverse mode. Adjoint of an
382       assignment is an addition.
383     o Changes to support compilation by TAMC (LR(1)
384       syntax) and by g77 under Linux ( 72 character
385       limit ).
386    
387    checkpoint15
388     Rewrote exchange routines to allow
389     o General tile <-> tile connectivity.

391     o Variable width overlap and exchange region widths.
392     o Hooks for sharing data via DMA, Arctic, Memory Channel,
393       shmput/shmget, VIA, SYSV shmem and every other cool
394       communication method.
395    
396    checkpoint14
397     Consistent isomorphism chages made. These allow dynamical core
398     to support both pressure and meters as a vertical coordinate.
399    
400    checkpoint13
401     Release which corrects global_max problem and a couple
402     of KGM time-averaging diagnostic errors. Also contains
403     a double-gyre experiment setup as well as the baseline
404     4 degree global template. The double gyre template is
405     organised to allow it to be applied automatically to
406     the baseline configuration.
407    
408    branch-point-rdot
409     A few tidy-ups have been made bt the real point of this
410     check-point (excuse the pun) is to allow a branch to be
411     made for the purposes of adding the rDot alterations.
412     I don't want to commit the rDot to the main-trunk until
413     we've actually tested it...
414    
415  checkpoint12  checkpoint12
416   Tidy up and added generic genmake script (formerly   Tidy up and added generic genmake script (formerly
417   configure script).   configure script).
