11 heimbach 1.52
12     checkpoint42
13     Fixed AD-related problems:
14     o Store directives up-to-date with re-arranged Adams-Bashforth
15     (mainly thermodynamics.F)
16     o New store directives for multi-dim. advection schemes
17     * new CPP flag ALLOW_MULTI_DIM_ADVECTION

19     (mainly gad_advection.F)
20     o Modified store directives for split of dynamics/thermodynamics
21     for the case ALLOW_KPP
22     o Cleaned argument list for timestep_tracer.F
23 adcroft 1.51
24     checkpoint41
25     o re-formatted/added comments in prologues of key subroutines
26     to work with protex
27 heimbach 1.47
28 adcroft 1.50 checkpoint40
29     o moved calc_gs, calc_gt and calc_tr1 back to model/src
30     o added FLT (floats) package from Arne along with demo. experiment
31     o re-arranged Adams-Bashforth scheme for tracers to allow easier
32     implementation of forward-in-time forcing terms
33     o more mods for non-linear free-surface including new variable
34     o modified multi-dim method to work on cube
35     o bug fix in KPP (from DM)
36    
37 adcroft 1.49 checkpoint40pre9
38     o added DST advection schemes
39     o fix MPI bug on SGI's
40     o modifications for non-linear free-surface
41     o fixed conditionals for fixed flow/passive tracer only mode
42     o added tension/strain form of stress tensor
43     o changes to commenting of arguments for TAF/TAMC
44     o added/updated many matlab scripts
45 adcroft 1.50 o added multi-dimensional advection method for tracers
46 adcroft 1.49
47 adcroft 1.48 checkpoint40pre8
48 heimbach 1.47 o new package rw/
49     Added method for dumping intermediate local arrays:
50     mdsio_writetile - same as mdsio_writefield except works from inside
51     bi,bj loop
52     mdsio_writelocal - same as mdsio_writetile except works for local
53     arrays
54     write_local_r? - higher-level wrapper for mdsio_writelocal
55     Controlled by diagFreq. Defaults to zero (ie. no dumps)
56     Example given at end of mom_vecinv.F that dumps some local arrays.
57     o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
58     control flux-form versus vector invariant code.
59     Switch is runtime flag vectorInvariantMomentum (defaults to false)
60     or genmake -DISABLE ...
61     o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
62     (additional storing is now needed for case vecinv;
63     currently nothing implemented to switch this storing off
64     in case fluxform is used since no CPP flag available).
65 heimbach 1.46
66     checkpoint40pre7
67     o bug fix in dynamics.F
68     calc_viscosity called before k=1,Nr loop.
69     o added some #ifdef's ALLOW_PASSIVE_TRACER
70     o cleaned initialisations in ctrl_map_ini
71     related to TAF
72 heimbach 1.45
73     checkpoint40pre6
74     o split dynamics into thermodynamics & dynamics
75     o corresponding split of calc_diffusivity into
76     calc_diffusivity, calc_viscosity
77     (kpp_calc_diff, kpp_calc_visc).
78     o Added diffkr, kapgm to control variables
79     o bug fix in gmredi_slope_limit for ldd97
80 adcroft 1.44
81     checkpoint40pre5
82     o proper initialization of Adams-Bashforth time stepping
83     + uses forward step for very first step of model (iter=0)
84     o re-generated *all* output since almost all output is modified by this
85     change (sorry but we've been putting this one off for about 2 years)
86     + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
87     *not* regenerated since they are already out of date and I don't
88     want to create the impression that they are suddenly working.
89     o removed KAP stuff for DEC's
90     o modified/added many .cvsignore files in */code and */input
91     o added new expt "solid-body.cs-32x32x1"
92     + this uses an alternative form of ini_curvilinear_grid.F which
93     is not necessarily any better than the current one...
94 heimbach 1.43
95     checkpoint40pre4
96     o added re-initialisations of utrans,vtrans,rtrans in
97     calc_common_factors which are crucial for TAF.
98     o extended iMin,jMin range for calc_common_factors,
99     calc_diffusivity
100     o added option ALLOW_PASSIVE_TRACER
101     o a few minor updates and fixes

110     o Added gradient check package
111     o Added routines for passive tracer handling
112     o Added carbon sequestration sensitivity experiment
113    
114 heimbach 1.39 checkpoint39
115     o Modifications and fixes to support TAMC
116     (mainly missing or wrong directives)
117     o Corrected common blocks when fooling TAMC to produce adjoint I/O
118     in addummy_in_stepping
119     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
120     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
121     o Included following packages:
122     cal: calendar
123     exf: external forcing
124     ecco: essential routines to control use of cal, exf
125     (NB: this is not the full ECCO environment)
126 heimbach 1.40 o disabled some packages by default in genmake
127 heimbach 1.39
128 heimbach 1.38 checkpoint38
129     o see notes_c37_adj.txt
130     o corrected wrong layer index in external_forcing_t
131     o replaced the_main_loop/forward_step by the_main_loop
132     o removed forceoutput from write_state
133     (replaced criteria for initial/final state)
134     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
135 jmc 1.36
136 jmc 1.37 checkpoint37
137     o mdsio.F routine split and packaged in pkg/mdsio
138     (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
139     used unless genmake -disable=mdsio)
140     o allow a more precise surface-geopotential gradient for the atmosphere
141     taking into account the change in space of Alpha (=1/rho) at the surface.
142     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
143     (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
144     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
145     Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
146     [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
147     o Time-Average diagnostics defined as a pseudo package "timeave".
148     o pickup files : old pickup (before c35) did not work with new code (c35
149     and after) unless activating 2 commented lines in initialise-varia.
150     o Non-Hydrostatic pickup file Pb fixed.
151     o bug with Rigid-lid version (since c35) fixed.
152    
153 jmc 1.36 checkpoint36
154 jmc 1.37 o implement Crank-Nickelson barotropic time-stepping
155 jmc 1.36 o recover Time-Average diagnostics
156     o fix Pb in checkpoint (PR#19)
157     o AIM become a standard package ; clean unused CPP_kees
158 jmc 1.35
159     checkpoint35
160     o subtantial rewrite of dynamics.f
161     o allows staggered time-stepping
162     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
163     o added bottom drag (linear + quadratic)
164 heimbach 1.33
165     checkpoint34
166     o Modified exchange routines for correct reverse simulation.
167     o Added verification output to comply with bug fix in impldiff.F
168     as of c33 (exp2, natl_box).
169     o Corrected store directives in dynamics.F
170     o Corrected array boundaries in impldiff.F
171     o Corrected array dimensions in gmredi.
172     Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
173 heimbach 1.34 o Added routine GLOBAL_SUM_INT to global_sum.F
174 heimbach 1.33 o Added mdsio_gl.F for ECCO purposes.
175 adcroft 1.32
176     checkpoint33
177     o Fixed bug in lower BC in impldiff.F
178     o Fixed confusion about units of forcing arrays in FFIELDS.h
179     namely Fu,Fv,Qnet,Qsw,EmPmR:
180     - Removed verification/natl_box/code/external_fields_scale.F
181     (did not differ from that in model/src)
182     - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
183     (see FFIELDS.h for description)
184     - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
185     kpp_calc.F and kpp_transport_t.F
186     - Removed model/src/external_fields_scale.F and calls to it
187     - verification/natl_box uses flux data with "atmospheric" sign so
188     a special version of external_fields_load.F is used to
189     change the data as it's read in. This way, the arrays
190     have the right units and signs at all times tha a user could
191     possibly use them.
192     o Corrected genmake to delete a temporary file during configuration
193 heimbach 1.31
194     checkpoint32
195     o Scaling of forcing fields moved from external_forcing.F to
196     external_fields_scale.F, called directly after loading fields.
197     o Surface relaxation terms added to surface tendency fields in
198     extra subroutine.

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

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

257     except the argument declarations. This was using up some memory.
258     o fixed macros like _ADT to work with both versions of Linux cpp
259     o cleaned up some unused and uninitialized variables
260     (helps when debugging with strict compile options)
261     o split up CPP_EEOPTIONS.h into options and macros
262     (macros are now in eesupp/inc/CPP_EEMACROS.h)
263     o patch for 2 processor JAM mode
264 adcroft 1.24
265     checkpoint25
266     o updates for OBCs and NH
267     o dramatically reduced memory usage
268     o added "JAM" routines for use on Artic network
269     o parameterization of convection by implicit vertical diffusion
270     o added a diagnostic of convective index
271     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
272     (this is was partly for OBCs and NH but also in anticipation of
273     an explicit free-surface option)

291     o Split-up mid-level I/O routines
292     o Updated input data for experiments 0,1,2,4 and 5
293     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
294 adcroft 1.18

296     o Tidied up open-boundaries some more
297     o Added non-hydrostatic code

322     accumulation in reverse mode. Adjoint of an
323     assignment is an addition.
324     o Changes to support compilation by TAMC (LR(1)
325     syntax) and by g77 under Linux ( 72 character
326     limit ).
327 cnh 1.14
328     checkpoint15
329     Rewrote exchange routines to allow

343     of KGM time-averaging diagnostic errors. Also contains
344     a double-gyre experiment setup as well as the baseline
345     4 degree global template. The double gyre template is
346     organised to allow it to be applied automatically to
347     the baseline configuration.
348 adcroft 1.11
349     branch-point-rdot
350     A few tidy-ups have been made bt the real point of this
351     check-point (excuse the pun) is to allow a branch to be
352     made for the purposes of adding the rDot alterations.
353     I don't want to commit the rDot to the main-trunk until
354     we've actually tested it...
355 cnh 1.10
