76      
77    checkpoint40pre8
78    o new package rw/
79      Added method for dumping intermediate local arrays:
80      mdsio_writetile - same as mdsio_writefield except works from inside
81                        bi,bj loop
82      mdsio_writelocal - same as mdsio_writetile except works for local
83                         arrays
84      write_local_r? - higher-level wrapper for mdsio_writelocal
85      Controlled by diagFreq. Defaults to zero (ie. no dumps)
86      Example given at end of mom_vecinv.F that dumps some local arrays.
87    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
88      control flux-form versus vector invariant code.
89      Switch is runtime flag vectorInvariantMomentum (defaults to false)
90      or genmake -DISABLE ...
91    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
92      (additional storing is now needed for case vecinv;
93      currently nothing implemented to switch this storing off
94      in case fluxform is used since no CPP flag available).
95    
96    checkpoint40pre7
97    o bug fix in dynamics.F
98      calc_viscosity called before k=1,Nr loop.
99    o added some #ifdef's ALLOW_PASSIVE_TRACER

104    o split dynamics into thermodynamics & dynamics
105    o corresponding split of calc_diffusivity into
106      calc_diffusivity, calc_viscosity
107      (kpp_calc_diff, kpp_calc_visc).
108    o Added diffkr, kapgm to control variables
109    o bug fix in gmredi_slope_limit for ldd97
110    
111    checkpoint40pre5
112    o proper initialization of Adams-Bashforth time stepping
113      + uses forward step for very first step of model (iter=0)
114    o re-generated *all* output since almost all output is modified by this
115      change (sorry but we've been putting this one off for about 2 years)
116      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
117        *not* regenerated since they are already out of date and I don't
118        want to create the impression that they are suddenly working.
119    o removed KAP stuff for DEC's
120    o modified/added many .cvsignore files in */code and */input
121    o added new expt "solid-body.cs-32x32x1"
122      + this uses an alternative form of ini_curvilinear_grid.F which
123        is not necessarily any better than the current one...
124    
125    checkpoint40pre4
126    o added re-initialisations of utrans,vtrans,rtrans in
127      calc_common_factors which are crucial for TAF.
128    o extended iMin,jMin range for calc_common_factors,
129      calc_diffusivity
130    o added option ALLOW_PASSIVE_TRACER

142    o Added carbon sequestration sensitivity experiment
143    
144    checkpoint39
145     o Modifications and fixes to support TAMC

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

237       -> new routines packages_...F
238       -> changes in initialise_fixed.F, initialise_varia.F
239       -> enables initialisation interface for ECCO package
240     o Rescaling of external forcing fields immediately after read
241       (removed from external_forcing.F)
242       -> new: surface_fields_scale.F
243       -> affects ini_foorcing.F, external_fields_load.F
244     o Computation of surface tendencies before tendency updates.
245       -> new: external_forcing_surf.F
246     o Change of variable names useGMRedi, useKPP, useECCO
247     o Further changes in dynamics.F, impldiff.F for TAMC
248     o Tested for experiments 0, 2, 4.
249       - not yet tested for GMRedi.
250       - not yet tested for KPP.
251    
252    checkpoint30
253     o Updates for OBCs
254     o New experiment for test OBCs (internal_wave)

257       kpp_dumpFreq and kpp_taveFreq
258     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
259       and entry for T90 in genmake
260    
261    checkpoint29

263    
264    checkpoint28

266     o Modified calculation of partial cell thickness to more robust algorithm
267     o config_summary.F: replaced write_1D_... by write_0D_...
268       read_write.F: added subroutines write_0D_...
269     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
270       included some initialisations required for TAMC.
271     o routine calc_isoslopes: modified sqrt computation to make it
272       differentiable for zero argument.
273     o routines dynamics, impldiff:
274       included store directives and tape key computations required for TAMC.
275     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
276    
277    checkpoint27
278     o fixed calc_isoslopes() to so that cancellation of terms in tensor
279       formulation works properly with variable resolution.
280     o restructured the calling tree between the_model_main() and dynamics()
281     o split initialise() into initialise_fixed() and initialise_varia()

284    
285    checkpoint26
286     o moved some #ifdef in optional routines to encompass everything
287       except the argument declarations. This was using up some memory.
288     o fixed macros like _ADT to work with both versions of Linux cpp
289     o cleaned up some unused and uninitialized variables
290       (helps when debugging with strict compile options)
291     o split up CPP_EEOPTIONS.h into options and macros
292       (macros are now in eesupp/inc/CPP_EEMACROS.h)
293     o patch for 2 processor JAM mode
294    
295    checkpoint25
296     o updates for OBCs and NH
297     o dramatically reduced memory usage
298     o added "JAM" routines for use on Artic network
299     o parameterization of convection by implicit vertical diffusion
300     o added a diagnostic of convective index
301     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
302       (this is was partly for OBCs and NH but also in anticipation of
303        an explicit free-surface option)

355       syntax) and by g77 under Linux ( 72 character
356       limit ).
357    
358    checkpoint15
359     Rewrote exchange routines to allow
360     o General tile <-> tile connectivity.

362     o Variable width overlap and exchange region widths.
363     o Hooks for sharing data via DMA, Arctic, Memory Channel,
364       shmput/shmget, VIA, SYSV shmem and every other cool
365       communication method.
366    
367    checkpoint14
368     Consistent isomorphism chages made. These allow dynamical core
369     to support both pressure and meters as a vertical coordinate.
370    
371    checkpoint13
372     Release which corrects global_max problem and a couple
373     of KGM time-averaging diagnostic errors. Also contains
374     a double-gyre experiment setup as well as the baseline
375     4 degree global template. The double gyre template is
376     organised to allow it to be applied automatically to
377     the baseline configuration.
378    
379    branch-point-rdot
380     A few tidy-ups have been made bt the real point of this
381     check-point (excuse the pun) is to allow a branch to be
382     made for the purposes of adding the rDot alterations.
383     I don't want to commit the rDot to the main-trunk until
384     we've actually tested it...
385
