55 to work with protex
56
57 checkpoint40
58 o moved calc_gs, calc_gt and calc_tr1 back to model/src
59 o added FLT (floats) package from Arne along with demo. experiment
60 o re-arranged Adams-Bashforth scheme for tracers to allow easier
61 implementation of forward-in-time forcing terms
62 o more mods for non-linear free-surface including new variable

75
76 checkpoint40pre8
77 o new package rw/
78 Added method for dumping intermediate local arrays:
79 mdsio_writetile - same as mdsio_writefield except works from inside
80 bi,bj loop
81 mdsio_writelocal - same as mdsio_writetile except works for local
82 arrays
83 write_local_r? - higher-level wrapper for mdsio_writelocal
84 Controlled by diagFreq. Defaults to zero (ie. no dumps)
85 Example given at end of mom_vecinv.F that dumps some local arrays.
86 o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
87 control flux-form versus vector invariant code.
88 Switch is runtime flag vectorInvariantMomentum (defaults to false)
89 or genmake -DISABLE ...
90 o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
91 (additional storing is now needed for case vecinv;
92 currently nothing implemented to switch this storing off
93 in case fluxform is used since no CPP flag available).
94
95 checkpoint40pre7
96 o bug fix in dynamics.F
97 calc_viscosity called before k=1,Nr loop.
98 o added some #ifdef's ALLOW_PASSIVE_TRACER
99 o cleaned initialisations in ctrl_map_ini
100 related to TAF
101
102 checkpoint40pre6
103 o split dynamics into thermodynamics & dynamics
104 o corresponding split of calc_diffusivity into

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116 *not* regenerated since they are already out of date and I don't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

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

262
263 checkpoint28

267 read_write.F: added subroutines write_0D_...
268 o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
269 included some initialisations required for TAMC.
270 o routine calc_isoslopes: modified sqrt computation to make it
271 differentiable for zero argument.
272 o routines dynamics, impldiff:
273 included store directives and tape key computations required for TAMC.
274 o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
275
276 checkpoint27
277 o fixed calc_isoslopes() to so that cancellation of terms in tensor
278 formulation works properly with variable resolution.
279 o restructured the calling tree between the_model_main() and dynamics()
280 o split initialise() into initialise_fixed() and initialise_varia()
281 o introduced initialization file pSurfInitFile for free surface (cg2d_x)
282 in new routine ini_psurf()
283
284 checkpoint26
285 o moved some #ifdef in optional routines to encompass everything
286 except the argument declarations. This was using up some memory.
287 o fixed macros like _ADT to work with both versions of Linux cpp
288 o cleaned up some unused and uninitialized variables

299 o added a diagnostic of convective index
300 o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
301 (this is was partly for OBCs and NH but also in anticipation of
302 an explicit free-surface option)
303 o initial state input files for U and V
304
305 checkpoint24

347 configuration "exp0".
348
349 checkpoint16
350 o Minor changes to exchange routines to support
351 accumulation in reverse mode. Adjoint of an
352 assignment is an addition.
353 o Changes to support compilation by TAMC (LR(1)
354 syntax) and by g77 under Linux ( 72 character
355 limit ).

375 organised to allow it to be applied automatically to
376 the baseline configuration.
377
378 branch-point-rdot
379 A few tidy-ups have been made bt the real point of this
380 check-point (excuse the pun) is to allow a branch to be
381 made for the purposes of adding the rDot alterations.
382 I don't want to commit the rDot to the main-trunk until
383 we've actually tested it...
