3 Notes on tags used in MITgcmUV
4 ==============================
5
6 o vertical grid option: allow to put the Interface at the middle between
7 2 cell-centers ; replace delZ in pkg/kpp by drF.
8 o GM Advective form: Tracers are advected using the residual transport (=
9 Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
10
11 checkpoint44g_post
12 o fix surface correction term in multiDimAdvection (affects plume_on_slope
13 results) ; ifdef missing in thermodynamics.F
14
15 checkpoint44f_pre,checkpoint44f_post
16 o added PTRACERS package
17 This allows an arbitrary number of passive tracers to be integrated
18 forward simultaneously with the dynamicaly model.
19 + Implemented so far:
20 - basic forward algorithm (time-stepping, advection, diffusion, convection)
21 - I/O and checkpointing
22 - GM/Redi *but* using the GM/Redi coefficient of Salt
23 + Not implemented so far:
24 - KPP
25 - OBCS
26 + No specific example supplied (yet) but global_ocean.90x40x15 has the
27 necessary data.ptracer file. Simply use -enable=ptracers and uncomment
28 line in data.pkg.
29 + This package is disabled by default since it increases storage.
30
31
32 o testscript: added -cleanup option
33 o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
34 b) enable to filter 2D fields.
35
36 checkpoint44e_pre,post
37 o re-wrote convective adjustment to use pre-calculated weights
38 Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
39 Adds: model/src/convective_weights.F, convectively_mixtracer.F
40 Original calls to convect() still in place.
41
42 chkpt44d_pre,post
43 o added missing EXCLUDE_MONITOR flags
44 o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
45 (incompatible typ in MIN/MAX expressions caused problems
46 on IBM SP3)
47 o in genmake added variable MAKEDEPEND
48 plus resetting for case SunOS
49 o added timer_stats.c routine for IBM SP3
50 o removed variables in dynamics
51 !!! I forgot to create tag chkpt44d_pre !!!

127 Added method for dumping intermediate local arrays:
128 mdsio_writetile - same as mdsio_writefield except works from inside
129 bi,bj loop
130 mdsio_writelocal - same as mdsio_writetile except works for local
131 arrays
132 write_local_r? - higher-level wrapper for mdsio_writelocal
133 Controlled by diagFreq. Defaults to zero (ie. no dumps)
134 Example given at end of mom_vecinv.F that dumps some local arrays.
135 o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
136 control flux-form versus vector invariant code.
137 Switch is runtime flag vectorInvariantMomentum (defaults to false)
138 or genmake -DISABLE ...
139 o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
140 (additional storing is now needed for case vecinv;
141 currently nothing implemented to switch this storing off
142 in case fluxform is used since no CPP flag available).
143
144 checkpoint40pre7
145 o bug fix in dynamics.F
146 calc_viscosity called before k=1,Nr loop.
147 o added some #ifdef's ALLOW_PASSIVE_TRACER

149 related to TAF
150
151 checkpoint40pre6

162 o re-generated *all* output since almost all output is modified by this
163 change (sorry but we've been putting this one off for about 2 years)
164 + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
165 *not* regenerated since they are already out of date and I don't
166 want to create the impression that they are suddenly working.
167 o removed KAP stuff for DEC's
168 o modified/added many .cvsignore files in */code and */input
169 o added new expt "solid-body.cs-32x32x1"
170 + this uses an alternative form of ini_curvilinear_grid.F which
171 is not necessarily any better than the current one...
172
173 checkpoint40pre4
174 o added re-initialisations of utrans,vtrans,rtrans in
175 calc_common_factors which are crucial for TAF.

196 in addummy_in_stepping
197 o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
198 o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
199 o Included following packages:
200 cal: calendar
201 exf: external forcing
202 ecco: essential routines to control use of cal, exf
203 (NB: this is not the full ECCO environment)
204 o disabled some packages by default in genmake
205
206 checkpoint38
207 o see notes_c37_adj.txt
208 o corrected wrong layer index in external_forcing_t
209 o replaced the_main_loop/forward_step by the_main_loop

211 (replaced criteria for initial/final state)
212 o added runtime flag for pre-C35 pickups: usePickupBeforeC35
213
214 checkpoint37
215 o mdsio.F routine split and packaged in pkg/mdsio
216 (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
217 used unless genmake -disable=mdsio)
218 o allow a more precise surface-geopotential gradient for the atmosphere
219 taking into account the change in space of Alpha (=1/rho) at the surface.
220 o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
221 (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
222 o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
223 Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
224 [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
225 o Time-Average diagnostics defined as a pseudo package "timeave".
226 o pickup files : old pickup (before c35) did not work with new code (c35
227 and after) unless activating 2 commented lines in initialise-varia.
228 o Non-Hydrostatic pickup file Pb fixed.
229 o bug with Rigid-lid version (since c35) fixed.
230
231 checkpoint36
232 o implement Crank-Nickelson barotropic time-stepping
233 o recover Time-Average diagnostics
234 o fix Pb in checkpoint (PR#19)
235 o AIM become a standard package ; clean unused CPP_kees
236

239 o allows staggered time-stepping
240 o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
241 o added bottom drag (linear + quadratic)
242
243 checkpoint34
244 o Modified exchange routines for correct reverse simulation.
245 o Added verification output to comply with bug fix in impldiff.F
246 as of c33 (exp2, natl_box).
247 o Corrected store directives in dynamics.F
248 o Corrected array boundaries in impldiff.F
249 o Corrected array dimensions in gmredi.
250 Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
251 o Added routine GLOBAL_SUM_INT to global_sum.F
252 o Added mdsio_gl.F for ECCO purposes.
253
254 checkpoint33
255 o Fixed bug in lower BC in impldiff.F
256 o Fixed confusion about units of forcing arrays in FFIELDS.h
257 namely Fu,Fv,Qnet,Qsw,EmPmR:
258 - Removed verification/natl_box/code/external_fields_scale.F
259 (did not differ from that in model/src)
260 - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
261 (see FFIELDS.h for description)
262 - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
263 kpp_calc.F and kpp_transport_t.F
264 - Removed model/src/external_fields_scale.F and calls to it
265 - verification/natl_box uses flux data with "atmospheric" sign so
266 a special version of external_fields_load.F is used to
267 change the data as it's read in. This way, the arrays
268 have the right units and signs at all times tha a user could
269 possibly use them.
270 o Corrected genmake to delete a temporary file during configuration
271
272 checkpoint32
273 o Scaling of forcing fields moved from external_forcing.F to
274 external_fields_scale.F, called directly after loading fields.
275 o Surface relaxation terms added to surface tendency fields in
276 extra subroutine.
277 o impldiff.F changed to avoid storing by TAMC of huge intermediate
278 fields.
279 o Changes in GMRedi to comply with packaging structure.
280 o Modifications and bug fixes in KPP package.
281 o Verification experiment for KPP added (verification/nat_box/)
282
283 checkpoint31
284 o Packages interface brought in line with defined standard
285 -> new routines packages_...F
286 -> changes in initialise_fixed.F, initialise_varia.F
287 -> enables initialisation interface for ECCO package
288 o Rescaling of external forcing fields immediately after read
289 (removed from external_forcing.F)
290 -> new: surface_fields_scale.F
291 -> affects ini_foorcing.F, external_fields_load.F
292 o Computation of surface tendencies before tendency updates.
293 -> new: external_forcing_surf.F
294 o Change of variable names useGMRedi, useKPP, useECCO

311
312 checkpoint28

318 included some initialisations required for TAMC.
319 o routine calc_isoslopes: modified sqrt computation to make it
320 differentiable for zero argument.
321 o routines dynamics, impldiff:
322 included store directives and tape key computations required for TAMC.
323 o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
324
325 checkpoint27
326 o fixed calc_isoslopes() to so that cancellation of terms in tensor
327 formulation works properly with variable resolution.
328 o restructured the calling tree between the_model_main() and dynamics()
329 o split initialise() into initialise_fixed() and initialise_varia()
330 o introduced initialization file pSurfInitFile for free surface (cg2d_x)
331 in new routine ini_psurf()
332
333 checkpoint26
334 o moved some #ifdef in optional routines to encompass everything
335 except the argument declarations. This was using up some memory.

349 o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
350 (this is was partly for OBCs and NH but also in anticipation of
351 an explicit free-surface option)
352 o initial state input files for U and V
353
354 checkpoint24

396 configuration "exp0".
397
398 checkpoint16
399 o Minor changes to exchange routines to support
400 accumulation in reverse mode. Adjoint of an
401 assignment is an addition.
402 o Changes to support compilation by TAMC (LR(1)
403 syntax) and by g77 under Linux ( 72 character
404 limit ).
405

420 Release which corrects global_max problem and a couple
421 of KGM time-averaging diagnostic errors. Also contains
422 a double-gyre experiment setup as well as the baseline

424 organised to allow it to be applied automatically to
425 the baseline configuration.
426
427 branch-point-rdot
428 A few tidy-ups have been made bt the real point of this
429 check-point (excuse the pun) is to allow a branch to be
430 made for the purposes of adding the rDot alterations.
431 I don't want to commit the rDot to the main-trunk until
432 we've actually tested it...
433
