15 heimbach 1.52
16     checkpoint42
17     Fixed AD-related problems:
18     o Store directives up-to-date with re-arranged Adams-Bashforth
19     (mainly thermodynamics.F)
20     o New store directives for multi-dim. advection schemes

24     o Modified store directives for split of dynamics/thermodynamics
25     for the case ALLOW_KPP
26     o Cleaned argument list for timestep_tracer.F
27 adcroft 1.51
28     checkpoint41
29     o re-formatted/added comments in prologues of key subroutines
30     to work with protex
31 heimbach 1.47
32 adcroft 1.50 checkpoint40
33     o moved calc_gs, calc_gt and calc_tr1 back to model/src
34     o added FLT (floats) package from Arne along with demo. experiment
35     o re-arranged Adams-Bashforth scheme for tracers to allow easier
36     implementation of forward-in-time forcing terms
37     o more mods for non-linear free-surface including new variable
38     o modified multi-dim method to work on cube
39     o bug fix in KPP (from DM)
40    
41 adcroft 1.49 checkpoint40pre9

50 adcroft 1.49
51 adcroft 1.48 checkpoint40pre8
52 heimbach 1.47 o new package rw/
53     Added method for dumping intermediate local arrays:
54     mdsio_writetile - same as mdsio_writefield except works from inside
55     bi,bj loop
56     mdsio_writelocal - same as mdsio_writetile except works for local
57     arrays
58     write_local_r? - higher-level wrapper for mdsio_writelocal
59     Controlled by diagFreq. Defaults to zero (ie. no dumps)
60     Example given at end of mom_vecinv.F that dumps some local arrays.
61     o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
62     control flux-form versus vector invariant code.
63     Switch is runtime flag vectorInvariantMomentum (defaults to false)
64     or genmake -DISABLE ...
65     o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
66     (additional storing is now needed for case vecinv;
67     currently nothing implemented to switch this storing off
68     in case fluxform is used since no CPP flag available).
69 heimbach 1.46
70     checkpoint40pre7
71     o bug fix in dynamics.F
72     calc_viscosity called before k=1,Nr loop.
73     o added some #ifdef's ALLOW_PASSIVE_TRACER
74     o cleaned initialisations in ctrl_map_ini
75     related to TAF
76 heimbach 1.45
77     checkpoint40pre6
78     o split dynamics into thermodynamics & dynamics
79     o corresponding split of calc_diffusivity into
80     calc_diffusivity, calc_viscosity
81     (kpp_calc_diff, kpp_calc_visc).
82     o Added diffkr, kapgm to control variables
83     o bug fix in gmredi_slope_limit for ldd97
84 adcroft 1.44
85     checkpoint40pre5
86     o proper initialization of Adams-Bashforth time stepping
87     + uses forward step for very first step of model (iter=0)
88     o re-generated *all* output since almost all output is modified by this
89     change (sorry but we've been putting this one off for about 2 years)
90     + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
91     *not* regenerated since they are already out of date and I don't
92     want to create the impression that they are suddenly working.
93     o removed KAP stuff for DEC's
94     o modified/added many .cvsignore files in */code and */input
95     o added new expt "solid-body.cs-32x32x1"
96     + this uses an alternative form of ini_curvilinear_grid.F which
97     is not necessarily any better than the current one...
98 heimbach 1.43
99     checkpoint40pre4
100     o added re-initialisations of utrans,vtrans,rtrans in
101     calc_common_factors which are crucial for TAF.
102     o extended iMin,jMin range for calc_common_factors,
103     calc_diffusivity

116     o Added carbon sequestration sensitivity experiment
117    
118 heimbach 1.39 checkpoint39
119     o Modifications and fixes to support TAMC

121     o Corrected common blocks when fooling TAMC to produce adjoint I/O
122     in addummy_in_stepping
123     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
124     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
125     o Included following packages:
126     cal: calendar
127     exf: external forcing
128     ecco: essential routines to control use of cal, exf
129     (NB: this is not the full ECCO environment)
130 heimbach 1.40 o disabled some packages by default in genmake
131 heimbach 1.39
132 heimbach 1.38 checkpoint38
133     o see notes_c37_adj.txt

138     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
139 jmc 1.36
140 jmc 1.37 checkpoint37
141     o mdsio.F routine split and packaged in pkg/mdsio
142     (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
143     used unless genmake -disable=mdsio)
144     o allow a more precise surface-geopotential gradient for the atmosphere
145     taking into account the change in space of Alpha (=1/rho) at the surface.
146     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
147     (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
148     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
149     Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
150     [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
151     o Time-Average diagnostics defined as a pseudo package "timeave".
152     o pickup files : old pickup (before c35) did not work with new code (c35
153     and after) unless activating 2 commented lines in initialise-varia.
154     o Non-Hydrostatic pickup file Pb fixed.
155     o bug with Rigid-lid version (since c35) fixed.
156    
157 jmc 1.36 checkpoint36
158 jmc 1.37 o implement Crank-Nickelson barotropic time-stepping
159 jmc 1.36 o recover Time-Average diagnostics
160     o fix Pb in checkpoint (PR#19)
161     o AIM become a standard package ; clean unused CPP_kees
162 jmc 1.35
163     checkpoint35
164     o subtantial rewrite of dynamics.f
165     o allows staggered time-stepping
166     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
167     o added bottom drag (linear + quadratic)
168 heimbach 1.33
169     checkpoint34
170     o Modified exchange routines for correct reverse simulation.
171     o Added verification output to comply with bug fix in impldiff.F
172     as of c33 (exp2, natl_box).
173     o Corrected store directives in dynamics.F
174     o Corrected array boundaries in impldiff.F
175     o Corrected array dimensions in gmredi.
176     Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
177 heimbach 1.34 o Added routine GLOBAL_SUM_INT to global_sum.F
178 heimbach 1.33 o Added mdsio_gl.F for ECCO purposes.
179 adcroft 1.32
180     checkpoint33
181     o Fixed bug in lower BC in impldiff.F
182     o Fixed confusion about units of forcing arrays in FFIELDS.h
183     namely Fu,Fv,Qnet,Qsw,EmPmR:
184     - Removed verification/natl_box/code/external_fields_scale.F
185     (did not differ from that in model/src)
186     - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
187     (see FFIELDS.h for description)
188     - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
189     kpp_calc.F and kpp_transport_t.F
190     - Removed model/src/external_fields_scale.F and calls to it
191     - verification/natl_box uses flux data with "atmospheric" sign so
192     a special version of external_fields_load.F is used to
193     change the data as it's read in. This way, the arrays
194     have the right units and signs at all times tha a user could
195     possibly use them.
196     o Corrected genmake to delete a temporary file during configuration
197 heimbach 1.31
198     checkpoint32
199     o Scaling of forcing fields moved from external_forcing.F to
200     external_fields_scale.F, called directly after loading fields.

211     -> new routines packages_...F
212     -> changes in initialise_fixed.F, initialise_varia.F
213     -> enables initialisation interface for ECCO package
214     o Rescaling of external forcing fields immediately after read
215     (removed from external_forcing.F)
216     -> new: surface_fields_scale.F
217     -> affects ini_foorcing.F, external_fields_load.F
218     o Computation of surface tendencies before tendency updates.
219     -> new: external_forcing_surf.F
220     o Change of variable names useGMRedi, useKPP, useECCO
221     o Further changes in dynamics.F, impldiff.F for TAMC
222     o Tested for experiments 0, 2, 4.

239     o Corrected initialization of hFacMin for difference vertical coordinates
240     o Modified calculation of partial cell thickness to more robust algorithm
241     o config_summary.F: replaced write_1D_... by write_0D_...
242     read_write.F: added subroutines write_0D_...
243     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
244     included some initialisations required for TAMC.
245     o routine calc_isoslopes: modified sqrt computation to make it
246     differentiable for zero argument.
247     o routines dynamics, impldiff:
248     included store directives and tape key computations required for TAMC.
249     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
250 adcroft 1.26
251     checkpoint27
252     o fixed calc_isoslopes() to so that cancellation of terms in tensor
253     formulation works properly with variable resolution.
254     o restructured the calling tree between the_model_main() and dynamics()

261     except the argument declarations. This was using up some memory.
262     o fixed macros like _ADT to work with both versions of Linux cpp
263     o cleaned up some unused and uninitialized variables
264     (helps when debugging with strict compile options)
265     o split up CPP_EEOPTIONS.h into options and macros
266     (macros are now in eesupp/inc/CPP_EEMACROS.h)
267     o patch for 2 processor JAM mode
268 adcroft 1.24
269     checkpoint25
270     o updates for OBCs and NH

274     o added a diagnostic of convective index
275     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
276     (this is was partly for OBCs and NH but also in anticipation of
277     an explicit free-surface option)

326     accumulation in reverse mode. Adjoint of an
327     assignment is an addition.
328     o Changes to support compilation by TAMC (LR(1)
329     syntax) and by g77 under Linux ( 72 character
330     limit ).

348     a double-gyre experiment setup as well as the baseline
349     4 degree global template. The double gyre template is
350     organised to allow it to be applied automatically to
351     the baseline configuration.
352 adcroft 1.11
353     branch-point-rdot
354     A few tidy-ups have been made bt the real point of this
355     check-point (excuse the pun) is to allow a branch to be
356     made for the purposes of adding the rDot alterations.
357     I don't want to commit the rDot to the main-trunk until
358     we've actually tested it...
