87    o added multi-dimensional advection method for tracers
88      
89    checkpoint40pre8
90    o new package rw/
91      Added method for dumping intermediate local arrays:
92      mdsio_writetile - same as mdsio_writefield except works from inside
93                        bi,bj loop
94      mdsio_writelocal - same as mdsio_writetile except works for local
95                         arrays
96      write_local_r? - higher-level wrapper for mdsio_writelocal
97      Controlled by diagFreq. Defaults to zero (ie. no dumps)
98      Example given at end of mom_vecinv.F that dumps some local arrays.
99    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
100      control flux-form versus vector invariant code.
101      Switch is runtime flag vectorInvariantMomentum (defaults to false)
102      or genmake -DISABLE ...
103    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
104      (additional storing is now needed for case vecinv;
105      currently nothing implemented to switch this storing off
106      in case fluxform is used since no CPP flag available).
107    
108    checkpoint40pre7
109    o bug fix in dynamics.F
110      calc_viscosity called before k=1,Nr loop.

116    o split dynamics into thermodynamics & dynamics
117    o corresponding split of calc_diffusivity into
118      calc_diffusivity, calc_viscosity
119      (kpp_calc_diff, kpp_calc_visc).
120    o Added diffkr, kapgm to control variables
121    o bug fix in gmredi_slope_limit for ldd97
122    
123    checkpoint40pre5
124    o proper initialization of Adams-Bashforth time stepping
125      + uses forward step for very first step of model (iter=0)
126    o re-generated *all* output since almost all output is modified by this
127      change (sorry but we've been putting this one off for about 2 years)
128      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
129        *not* regenerated since they are already out of date and I don't
130        want to create the impression that they are suddenly working.
131    o removed KAP stuff for DEC's
132    o modified/added many .cvsignore files in */code and */input
133    o added new expt "solid-body.cs-32x32x1"
134      + this uses an alternative form of ini_curvilinear_grid.F which
135        is not necessarily any better than the current one...
136    
137    checkpoint40pre4
138    o added re-initialisations of utrans,vtrans,rtrans in
139      calc_common_factors which are crucial for TAF.
140    o extended iMin,jMin range for calc_common_factors,
141      calc_diffusivity
142    o added option ALLOW_PASSIVE_TRACER
143    o a few minor updates and fixes
144    
145    checkpoint40pre3
146    o created calc_gtr1.F for gad package
147    o split the_main_loop and re-introduced forward_step

150    checkpoint40pre2
151    o Updated to latest branch of AJA, JMC
152    o Added gradient check package
153    o Added routines for passive tracer handling
154    o Added carbon sequestration sensitivity experiment
155    
156    checkpoint39
157     o Modifications and fixes to support TAMC
158       (mainly missing or wrong directives)
159     o Corrected common blocks when fooling TAMC to produce adjoint I/O
160       in addummy_in_stepping
161     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
162     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
163     o Included following packages:
164       cal: calendar
165       exf: external forcing
166       ecco: essential routines to control use of cal, exf
167             (NB: this is not the full ECCO environment)
168     o disabled some packages by default in genmake
169    
170    checkpoint38
171     o see notes_c37_adj.txt
172     o corrected wrong layer index in external_forcing_t
173     o replaced the_main_loop/forward_step by the_main_loop
174     o removed forceoutput from write_state
175       (replaced criteria for initial/final state)
176     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
177    
178    checkpoint37
179     o mdsio.F routine split and packaged in pkg/mdsio
180       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
181        used unless genmake -disable=mdsio)
182     o allow a more precise surface-geopotential gradient for the atmosphere
183       taking into account the change in space of Alpha (=1/rho) at the surface.
184     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
185       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
186     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
187       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
188       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
189     o Time-Average diagnostics defined as a pseudo package "timeave".
190     o pickup files : old pickup (before c35) did not work with new code (c35
191       and after) unless activating 2 commented lines in initialise-varia.
192     o Non-Hydrostatic pickup file Pb fixed.
193     o bug with Rigid-lid version (since c35) fixed.  
194    
195    checkpoint36
196     o implement Crank-Nickelson barotropic time-stepping
197     o recover Time-Average diagnostics
198     o fix Pb in checkpoint (PR#19)
199     o AIM become a standard package ; clean unused CPP_kees
200    
201    checkpoint35
202     o subtantial rewrite of dynamics.f
203     o allows staggered time-stepping
204     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
205     o added bottom drag (linear + quadratic)
206    
207    checkpoint34
208     o Modified exchange routines for correct reverse simulation.
209     o Added verification output to comply with bug fix in impldiff.F
210       as of c33 (exp2, natl_box).
211     o Corrected store directives in dynamics.F
212     o Corrected array boundaries in impldiff.F
213     o Corrected array dimensions in gmredi.
214       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
215     o Added routine GLOBAL_SUM_INT to global_sum.F
216     o Added mdsio_gl.F for ECCO purposes.
217    
218    checkpoint33
219     o Fixed bug in lower BC in impldiff.F
220     o Fixed confusion about units of forcing arrays in FFIELDS.h
221       namely Fu,Fv,Qnet,Qsw,EmPmR:
222       - Removed verification/natl_box/code/external_fields_scale.F
223         (did not differ from that in model/src)
224       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
225         (see FFIELDS.h for description)
226       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
227         kpp_calc.F and kpp_transport_t.F
228       - Removed model/src/external_fields_scale.F and calls to it
229       - verification/natl_box uses flux data with "atmospheric" sign so
230         a special version of external_fields_load.F is used to
231         change the data as it's read in. This way, the arrays
232         have the right units and signs at all times tha a user could
233         possibly use them.
234     o Corrected genmake to delete a temporary file during configuration
235    
236    checkpoint32
237     o Scaling of forcing fields moved from external_forcing.F to
238       external_fields_scale.F, called directly after loading fields.
239     o Surface relaxation terms added to surface tendency fields in
240       extra subroutine.
241     o impldiff.F changed to avoid storing by TAMC of huge intermediate
242       fields.
243     o Changes in GMRedi to comply with packaging structure.
244     o Modifications and bug fixes in KPP package.
245     o Verification experiment for KPP added (verification/nat_box/)
246    
247    checkpoint31
248     o Packages interface brought in line with defined standard
249       -> new routines packages_...F
250       -> changes in initialise_fixed.F, initialise_varia.F
251       -> enables initialisation interface for ECCO package
252     o Rescaling of external forcing fields immediately after read
253       (removed from external_forcing.F)
254       -> new: surface_fields_scale.F
255       -> affects ini_foorcing.F, external_fields_load.F
256     o Computation of surface tendencies before tendency updates.
257       -> new: external_forcing_surf.F
258     o Change of variable names useGMRedi, useKPP, useECCO
259     o Further changes in dynamics.F, impldiff.F for TAMC
260     o Tested for experiments 0, 2, 4.
261       - not yet tested for GMRedi.
262       - not yet tested for KPP.
263    
264    checkpoint30
265     o Updates for OBCs
266     o New experiment for test OBCs (internal_wave)

268     o Updates for KPP: calculation of viscosity corrected, new variables
269       kpp_dumpFreq and kpp_taveFreq
270     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
271       and entry for T90 in genmake
272    
273    checkpoint29

275    
276    checkpoint28
277     o Corrected initialization of hFacMin for difference vertical coordinates
278     o Modified calculation of partial cell thickness to more robust algorithm
279     o config_summary.F: replaced write_1D_... by write_0D_...
280       read_write.F: added subroutines write_0D_...
281     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
282       included some initialisations required for TAMC.
283     o routine calc_isoslopes: modified sqrt computation to make it
284       differentiable for zero argument.
285     o routines dynamics, impldiff:
286       included store directives and tape key computations required for TAMC.
287     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
288    
289    checkpoint27
290     o fixed calc_isoslopes() to so that cancellation of terms in tensor
291       formulation works properly with variable resolution.
292     o restructured the calling tree between the_model_main() and dynamics()
293     o split initialise() into initialise_fixed() and initialise_varia()

295       in new routine ini_psurf()
296    
297    checkpoint26
298     o moved some #ifdef in optional routines to encompass everything
299       except the argument declarations. This was using up some memory.
300     o fixed macros like _ADT to work with both versions of Linux cpp
301     o cleaned up some unused and uninitialized variables
302       (helps when debugging with strict compile options)
303     o split up CPP_EEOPTIONS.h into options and macros
304       (macros are now in eesupp/inc/CPP_EEMACROS.h)
305     o patch for 2 processor JAM mode
306    
307    checkpoint25
308     o updates for OBCs and NH
309     o dramatically reduced memory usage
310     o added "JAM" routines for use on Artic network
311     o parameterization of convection by implicit vertical diffusion
312     o added a diagnostic of convective index
313     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
314       (this is was partly for OBCs and NH but also in anticipation of
315        an explicit free-surface option)

364       accumulation in reverse mode. Adjoint of an
365       assignment is an addition.
366     o Changes to support compilation by TAMC (LR(1)
367       syntax) and by g77 under Linux ( 72 character
368       limit ).
369    
370    checkpoint15
371     Rewrote exchange routines to allow
372     o General tile <-> tile connectivity.
373     o TAMC reverse mode flag ( is this really needed? )
374     o Variable width overlap and exchange region widths.
375     o Hooks for sharing data via DMA, Arctic, Memory Channel,
376       shmput/shmget, VIA, SYSV shmem and every other cool
377       communication method.
378    
379    checkpoint14
380     Consistent isomorphism chages made. These allow dynamical core
381     to support both pressure and meters as a vertical coordinate.
382    
383    checkpoint13
384     Release which corrects global_max problem and a couple
385     of KGM time-averaging diagnostic errors. Also contains
386     a double-gyre experiment setup as well as the baseline
387     4 degree global template. The double gyre template is
388     organised to allow it to be applied automatically to
389     the baseline configuration.
390    
391    branch-point-rdot
392     A few tidy-ups have been made bt the real point of this
393     check-point (excuse the pun) is to allow a branch to be
394     made for the purposes of adding the rDot alterations.
395     I don't want to commit the rDot to the main-trunk until
396     we've actually tested it...
397    
398    checkpoint12
