29 to work with protex
30
31 checkpoint40
32 o moved calc_gs, calc_gt and calc_tr1 back to model/src
33 o added FLT (floats) package from Arne along with demo. experiment
34 o re-arranged Adams-Bashforth scheme for tracers to allow easier
35 implementation of forward-in-time forcing terms
36 o more mods for non-linear free-surface including new variable
37 o modified multi-dim method to work on cube
38 o bug fix in KPP (from DM)
39
40 checkpoint40pre9

49
50 checkpoint40pre8
51 o new package rw/
52 Added method for dumping intermediate local arrays:
53 mdsio_writetile - same as mdsio_writefield except works from inside
54 bi,bj loop
55 mdsio_writelocal - same as mdsio_writetile except works for local
56 arrays
57 write_local_r? - higher-level wrapper for mdsio_writelocal
58 Controlled by diagFreq. Defaults to zero (ie. no dumps)
59 Example given at end of mom_vecinv.F that dumps some local arrays.
60 o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
61 control flux-form versus vector invariant code.
62 Switch is runtime flag vectorInvariantMomentum (defaults to false)
63 or genmake -DISABLE ...
64 o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
65 (additional storing is now needed for case vecinv;
66 currently nothing implemented to switch this storing off
67 in case fluxform is used since no CPP flag available).
68
69 checkpoint40pre7
70 o bug fix in dynamics.F
71 calc_viscosity called before k=1,Nr loop.

74 related to TAF
75
76 checkpoint40pre6

82 o bug fix in gmredi_slope_limit for ldd97
83
84 checkpoint40pre5
85 o proper initialization of Adams-Bashforth time stepping
86 + uses forward step for very first step of model (iter=0)
87 o re-generated *all* output since almost all output is modified by this
88 change (sorry but we've been putting this one off for about 2 years)
89 + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
90 *not* regenerated since they are already out of date and I don't
91 want to create the impression that they are suddenly working.
92 o removed KAP stuff for DEC's
93 o modified/added many .cvsignore files in */code and */input
94 o added new expt "solid-body.cs-32x32x1"
95 + this uses an alternative form of ini_curvilinear_grid.F which
96 is not necessarily any better than the current one...
97
98 checkpoint40pre4
99 o added re-initialisations of utrans,vtrans,rtrans in

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

212 -> enables initialisation interface for ECCO package
213 o Rescaling of external forcing fields immediately after read
214 (removed from external_forcing.F)
215 -> new: surface_fields_scale.F
216 -> affects ini_foorcing.F, external_fields_load.F
217 o Computation of surface tendencies before tendency updates.
218 -> new: external_forcing_surf.F
219 o Change of variable names useGMRedi, useKPP, useECCO

245 differentiable for zero argument.
246 o routines dynamics, impldiff:
247 included store directives and tape key computations required for TAMC.
248 o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
249
250 checkpoint27
251 o fixed calc_isoslopes() to so that cancellation of terms in tensor
252 formulation works properly with variable resolution.
253 o restructured the calling tree between the_model_main() and dynamics()
254 o split initialise() into initialise_fixed() and initialise_varia()
255 o introduced initialization file pSurfInitFile for free surface (cg2d_x)
256 in new routine ini_psurf()
257
258 checkpoint26

321 configuration "exp0".
322
323 checkpoint16
324 o Minor changes to exchange routines to support
325 accumulation in reverse mode. Adjoint of an
326 assignment is an addition.
327 o Changes to support compilation by TAMC (LR(1)
328 syntax) and by g77 under Linux ( 72 character
329 limit ).

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