3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o new package "land": provide surface BC for AIM.
7    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
8    o AIM: use true log-P extrapolation for near surface temp (= as in
9        F.Molteni paper) ; update aim.5l_cs output.
10    o New variable in PARM03 for more flexible pickups
11    
12    checkpoint50g_post
13    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
14      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
15      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
16        made the default because of faster convergence than ADI
17    
18    checkpoint50f_post
19    o exf totally restructured
20      - replaced all exf_set_ routines by one generic exf_set_gen.F
21        and made sure it's still differentiable
22      - split exf_getffields.F into new exf_bulkformulae.F
23      - exf_inscal_/exf_outscal_ suffixes consistent with field names
24      - updated adjoint/makefile and relevant verif. accordingly
25    
26    checkpoint50f_pre
27     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
28          + change Evap over land. (update aim.5l_cs output)
29     o added missing .cvsignores and made uniform across expts
30     o changed configuration of tidal_basin_2d expt
31     o added pkg/debug functions for tracing code in fatal crashes
32     o tidied pkg/monitor to use MONITOR_OPTIONS.h
33     o new fn in pkg/monitor to stop model if solution grows too big
34     o removed lots of single quotes from comments
35    
36    checkpoint50e_post
37    o make KPP work with PTRACERS
38     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
39       nearly a copy of kpp_transport_s
40     - there is no analogue to SurfaceTendencyS, so I have to use
41       gPtr(of the surface layer) instead
42    o add a new platform SunFire+mpi (SunFire 15000) to genmake
43    checkpoint50e_pre
44    
45    checkpoint50d_post
46    o change kpp output from multiple-record state files to single-record state
47      files analogous to write_state.F
48    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
49      analogous to the cg2d-related output.
50    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
51      so that writing to internal file fn (with length 512) fails.
52    checkpoint50d_pre
53    
54    checkpoint50c_post
55    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
56    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
57    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
58    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
59    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
60    
61    checkpoint50c_pre
62    Merging from release1_p13:
63    o bug fix for pkg/seaice dynamic solver
64    o Added SEAICE_initialHEFF to pkg/seaice
65    
66    checkpoint50b_post
67    o store u*,v* in gU,V instead of in guNm1,gvNm1
68    o in order to put the momForcing out of the Adams-Bashforth:
69      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
70      to timestep.F
71    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
72    o re-generate output for highly sensitive test-exp:
73       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
74    
75    checkpoint50b_pre
76    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
77    o corrected CPP option mismatch in exf_Bulk... functions for case
78      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
79    
80    checkpoint50a_post
81    o Bug fix for merging between c50 and KPP.
82      ikey was passed from thermodynamics to kpp_calc via
83      common block rather than being recomputed in kpp_calc,
84      in contradiction with new key itdkey.
85      New key ikppkey created, and tamc.h headers updated.
86    
87    checkpoint50
88    - 2nd step of merge with ecco-branch:
89      merge changes in ecco-branch back into main trunk
90    - bug fix in find_alpha
91    - more storing in gmredi_calc_tensor.F, kpp_routines.F
92    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
93    - merged some sliced AD support routines
94    
95    checkpoint49
96    merged from ecco-branch:
97    o exf:
98      - Enable initialisation of forcing fields to constant
99        (runtime) values.
100      - in exf_getffields.F
101        Reduce i-/j-loop to interior domain, discarding overlaps.
102        That also fixes wrong TAF-key computations for key_1, key_2
103        with bulf formulae.
104      - exf_init.F modify #ifdef for exf_init_evap
105      - exf_getffieldrec.F, ctrl_getrec.F
106        The following INT-usages are not safe:
107          fldsecs  = int(fldsecs/fldperiod)*fldperiod
108          fldcount = int(fldsecs/fldperiod) + 1
109        and were modified.
110    o autodiff: checkpoint_lev...
111      - updated storing for bulk formulae (some arrays were missing)
112      - added state for seaice package
113      - synchronized with main branch
114    o DIVA:
115      Modif.s in
116      - the_main_loop.F
117      - the_model_main.F
118      and added cost_final_restore.F cost_final_store.F
119      o With these changes, it is possible to fully separate
120        the first forward run to compute the cost function (mdthe_main_loop)
121        and adjoint runs over individual DIVA intervals (adthe_main_loop)
122        into separate model executions.
123        This enables better tuning of DIVA to given queue sizes.
124      o Loss of cost function value in consecutive DIVA runs is
125        fixed by storing to 'costfinal' file.
126      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
127        beginning/end of adjoint integration is accounted for.
128      The current changes apply to TAF-1.4.26.
129      TAF has one remaining bug, requiring one manual change
130      (see MITgcm manual).
131    o cal: synchronized between MAIN and ecco-branch
132    
133    checkpoint48i_post
134    o Changes to restore differentiability of code w.r.t. previous tag
135      (mostly adding new routines to make list and replacing
136      pressure by totPhiHyd).
137    o Updated and merged grdchk package
138      - has both ADM and TLM checks
139      - works for single- and multi-proc.
140      - output cleaned
141      - worked successfully for parallel DIVA
142    o genmake:
143      - Adding -platform=SP4
144      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
145    o Modif. for DIVA:
146      ctrl_unpack should not be called in intermediate DIVA interval.
147      (similar thing would apply for active files such as
148      tbar, sbar, psbar, which should not be reinitialised;
149      only relevant for ecco-branch)
150    
151    checkpoint48h_post
152    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
153    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
154    o Added SEAICE_initialHEFF to pkg/seaice
155    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
156    
157    checkpoint48g_post
158    --- EOS:
159    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
160      store total Potential in totPhyHyd for diagnostics & EOS.
161    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
162    --- Pressure/geopotential gradient:
163    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
164    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
165      ( changes results of global_ocean_pressure )
166    o NLFS + z-coord.: add eta*Rho' contribution.
167    o accurate phiHyd when using interface-W at the middle between 2 centers
168     ( changes results of ideal_2D_oce )
169    o includes r* 2nd term in potential gradient.
170    
171    checkpoint48f_post
172    Merging from release1_p12:
173    o Modifications for using pkg/exf with pkg/seaice
174      - improved description of the various forcing configurations
175      - added basic radiation bulk formulae to pkg/exf
176      - units/sign fix for evap computation in exf_getffields.F
177      - updated verification/global_with_exf/results/output.txt
178    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
179      (SBO) core products, including oceanic mass, center-of-mass,
180      angular, and bottom pressure (see pkg/sbo/README.sbo).
181    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
182      to avoid negative values in shallow regions.
183      - updated verification/natl_box/results/output.txt
184      - updated verification/lab_sea/results/output.txt
185    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
186    o Added useSingleCpuIO option (see PARAMS.h).
187    o Updated useSingleCpuIO option in mdsio_writefield.F to
188      work with multi-field files, e.g., for single-file pickup.
189    o pkg/seaice:
190      - bug fix in growth.F: QNET for no shortwave case
191      - added HeffFile for specifying initial sea-ice thickness
192      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
193    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
194      kpp_transport_t.F, forward_step.F, and the_main_loop.F
195    o pkg/seaice:
196      - adjoint-friendly modifications
197      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
198    
199    checkpoint48e_post
200    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
201    o dynamics: change definition of computational domain & adapt mom_fluxform
202      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
203    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
204        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
205        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
206        global_ocean.90x40x15 global_with_exf global_ocean_pressure
207        inverted_barometer solid-body.cs-32x32x1
208      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
209    
210    checkpoint48d_post
211    o in preparation for r*:
212     a) use pre-computed gradient of hydrostatic potential:
213        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
214     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
215        => affects results of glob_oce_pressure (different truncation error)  
216      update output.txt of ideal_2D_oce & global_ocean_pressure
217    
218    checkpoint48d_pre
219    o in preparation for r*:
220      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
221      pass the 2 comp. of the grad. as arguments to momentum S/R.
222      but for the moment, only used if it does not change the results.
223    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
224    
225    checkpoint48c_post
226    Modifications in treatment of initial flux forcing controls
227    to avoid extra storing of flux fields.
228    
229    checkpoint48c_pre
230    o Added tidal_basin_2d experiment (currently 1D!)
231    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
232    
233    checkpoint48b_post
234    o r* coordinate added in #ifdef NONLIN_FRSURF block.
235     (modification to pressure gradient not yet implemented)
236    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
237      (for U & V) that are used for vertical advection of momentum.
238    
239    checkpoint48a_post
240    o In preparation for r*, use temp. array to compute vertical transport
241       in flux-form momentum pkg. => change results of few test-exp.
242      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
243                        lab_sea, natl_box & plume_on_slope
244    
245    checkpoint48
246    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
247    
248    checkpoint47j_post
249    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
250    o moved adexch from forward_step to addummy_in_stepping
251    o added exch in ctrl_map_...
252    o aveFreq.=0. at end of cost_final to avoid overwrite in
253      reverse checkpointing loop
254    o Yet more changes in gmredi:
255      * adgmredi_calc_tensor
256        avoiding all recomputation of gmredi_slope_limit
257      * adgmredi_x/y/rtransport
258        added flag for excessive storing to avoid recomp. of
259        u/v/rtans, dTdx/y/z
260        -> this is not really necessary and very memory-consuming
261      * adgmredi_slope_psi:
262        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
263      * gmredi_slope_limit
264        re-activated full calculation of taperfct for case 'ac02'
265    o updating verification/ adjoints of carbon, global_ocean.90x40x15
266    
267    checkpoint47i_post
268    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
269    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
270      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
271    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
272    o gmredi: fix few bugs.
273    
274    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
275    This will be a good checkpoint to plug into the ecco-branch.
276    o few modif.'s to get latest version adjointed
277      (mainly kick out code in ini_linear_phisurf)
278    o modif's to run adjoint with exactConserv
279    o case GM_BOLUS_ADVEC should be cleaned
280      S/R gmredi_slope_psi should be cleaned
281    o verification/carbon now has exactConserv=.TRUE.
282    
283    checkpoint47g_post
284    o time-average AIM output: becomes independent from statvars time-average
285      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
286    o After TAF bug fix:
287      Tested adjoint of gmredi package.
288      Tests were done with checkpoint47 rather than with latest
289      checkpoint47f_post since the latter is broken for the adjoint
290      verification/carbon/ contains both ADM and TLM gradient checks.
291    Here they are, before they get changed/lost/stolen.
292    Mostly modif.'s to fix numerical sensitivities.
293    Gradient checks OK for
294    - GM_taper_scheme:
295      * clipping
296      * ac02
297      * linear
298      * glw91
299      * dm95
300      * ldd97
301    - GMREDI_OPTIONS:
302      * GM_VISBECK_VARIABLE_K
303      * GM_NON_UNITY_DIAGONAL
304      * GM_EXTRA_DIAGONAL
305      * GM_BOLUS_ADVEC
306    in conjunction with data.gmredi parameters to be checked in
307    in a few minutes under verification/carbon/code/
308    
309    checkpoint47f_post
310    Merging from release1_p10:
311    o modifications for using pkg/exf with pkg/seaice
312      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
313        and SEAICE_EXTERNAL_FLUXES
314      - pkg/exf CPP options EXF_READ_EVAP and
315        EXF_NO_BULK_COMPUTATIONS
316      - usage examples are Experiments 8 and 9 in
317        verification/lab_sea/README
318      - verification/lab_sea default experiment now uses
319        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
320    
321    checkpoint47e_post
322    o created a tag prior to creating a branch
323    
324    checkpoint47d_post
325    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
326      at the bottom boundary had an erroneous half slip boundary condition
327    o added bottom drag and no slip boundary condition capabilities to
328      oceanic pressure coordinates code
329    o added new verification experiment global_ocean_pressure, this experiment is
330      also described in the tutorial section of the manual
331    checkpoint47d_pre
332    
333    checkpoint47c_post
334    o Added a verification experiment for a global cubed-sphere ocean run
335      -  verification/global_ocean.cubed32x32x30
336      -  uses pkg/therm_seaice and pkg/bulk_forcing
337    
338    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
339    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
340      when using P-coordinate; only implemented for atmospheric config.
341    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
342      NOTES: requires option NONLIN_FRSURF to be "#define".
343    o update advect_xz/results/output.txt (left from checkpoint44g_post)
344    
345    checkpoint47b_post
346    Merging from release1_p9:
347    o pkg/seaice
348      - removed GOTO's and added taf directives
349      - double precision constants to reduce the g77 (Linux)
350        to F77 (SGI) differences reported in release1_p8
351    o tools/genmake
352      - added SGI options
353    o verification/testscript
354      - updated to that of checkpoint47a_post
355    o verification/global_ocean.90x40x15/input/eedata
356      - modified for SGI f77 compatibility
357    o verification/lab_sea
358      - added description of sea-ice model
359      - added missing matlab routines
360      - added test of thermodynamics parallelization
361    
362    checkpoint47a_post
363    o new pkg: aim_v23
364     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
365       for now, keep the same surface forcing as before.
366     - Part-Cell implemented into AIM; check that Heat & Water are conserved
367     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
368     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
369    o add diagnostic of surface correction term in monitor output
370    
371    o bulk_force and therm_seaice
372    - Two packages:  bulk_force (Bulk forcing)
373      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
374    - Earlier integration from Stephaine Dutkiewicz
375      and Patrick Heimbach.
376    - Two ifdef statements for compile time,
377       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
378    
379    checkpoint47
380    differentiable version of checkpoint46n_post
381    o bug fix in quasihydrostaticterms
382    o * "clean" adjoint code (in terms of extensive recomputations)
383        can now be obtained for all GMREDI options (i.e. for
384        - GM_VISBECK_VARIABLE_K
385        - GM_NON_UNITY_DIAGONAL
386        - GM_EXTRA_DIAGONAL
387        - GM_BOLUS_ADVEC )
388      * However, wrong gradient check problem remains unsolved.
389      * New CPP options have been introduced for different
390        tapering schemes
391    o external_fields_load now part of differentiation list
392    o pressure needs multiple storing;
393      would be nice to have store_pressure at beginning or
394      end of forward_step, e.g. by having phiHyd global (5-dim.)
395      (NB: pressure is needed for certain cases in find_rho,
396      which is also invoked through convective_adjustment).
397    o recomputations in find_rho for cases
398     'JMD95'/'UNESCO' or 'MDJWF' are OK.
399    o #define ATMOSPHERIC_LOADING should be differentiable
400    o ini_forcing shifted to begining of initialise_varia
401    o Incorporating QNVS line search routines into MITgcm
402      (this is separate code, and therefore not under pkg)
403      lsopt/, optim/
404    o Updated verification/carbon/
405      - #define GM_VISBECK_VARIABLE_K
406      - GM_taper_scheme    = 'ldd97'    
407    
408    checkpoint46n_post
409    Merging from release1_p8:
410    o verification/natl_box:
411      updating new external_fields_load routine
412    o New package: pkg/seaice
413      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
414      The sea-ice code is based on Hibler (1979-1980).
415      Two sea-ice dynamic solvers, ADI and LSR, are included.
416      In addition to computing prognostic sea-ice variables and diagnosing
417      the forcing/external data fields that drive the ocean model,
418      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
419      The implied surface heat flux is then stored in variable
420      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
421      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
422      non-local transport term.  Because this call precedes model
423      thermodynamics, temperature under sea-ice may not be "exactly" at
424      the freezing point by the time theta is dumped or time-averaged.
425      N.B.: fairly large differences in accuracy occur across
426            different platforms/compilers; comparison between
427            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
428            generated output gives:

436    o GAD:
437      - generated new common blocks to account for call of
438        same gad routines with differing traceridentities
439        (needed to modify tracerIdentity indices in GAD.h)
440      - generated separate common blocks for case useCubedSphereExchange
441        (Department of Futurology)
442      - parameter lists to gmredi_?transport: added tracerIdentity
443      - added new key indices to tamc.h
444    o external_fields_load:
445      - added this routine to TAF list
446      - needed to make some common blocks global and additional storing
447        along the same lines as exf package (checkpoint_lev?_directives.h)
448    o exf:
449      updated external forcing package
450      - bug fixes carried over from ecco-branch
451        (missing OBCS_OPTIONS.h in two routines)
452      - enable easy to use "no forcing".
453      - added exf I/O for atmospheric loading
454      - added exf I/O for runoff data
455      - transfered scaling between exf <-> MITgcm to exf namelist
456    o Adding new verification experiment global_with_exf.
457      This verification experiment is almost identical to the
458      global_ocean.90x40x15 experiment, except that it uses
459      the exf (and cal) package instead of the
460      external_fields_load routine (cf README file).
461    
462    checkpoint46m_post
463    o modified testscript to return -- when there are no lines of "%MON" output
464    o added new flag "quasiHydrostatic" for QH mode
465      and new routine quasihydrostaticterms()
466    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
467      New routine: mom_u_coriolis_nh()
468    o fixed sign of non-hydrostatic metric terms in u and v equations.
469      Depend on correct sign of gravitySign.
470  o added work.pc* to .cvsignore in aim directories using ifc  o added work.pc* to .cvsignore in aim directories using ifc
471  o introduced flag for controllin non-hydrostatic metric terms  o introduced flag for controllin non-hydrostatic metric terms
472  o removed gravitySign from PARM04  o removed gravitySign from PARM04
