3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
7      - modified verification/lab_sea and natl_box_adjoint accordingly
8    
9    checkpoint54
10    checkpoint53g_post
11    o prepare splitting of thermodynamics: store convect.counter in common block
12    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
13      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
14    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
15    o new parameter "nShapS": allow to treat differently S from T (nShapT)
16    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
17    o restore adjointability
18    
19    checkpoint53f_post
20    o modifications that affect AIM experiment results (update output.txt):
21      - no advection of S at top interface Nr (pkg/generic_advdiff)
22      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
23    o AIM pkg:
24      - include stability function into surf.Flux derivative relative to Tsurf
25      - calculate clear-sky radiation & surface temp. change (for diagnostics)
26    
27    checkpoint53e_post
28    o merged cylindrical coord configuration
29    o added rotating_tank experiment
30    checkpoint53e_pre
31    
32    checkpoint53d_post
33    o faulks upgraded: re-generate output.txt that have changed:
34       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
35    o Added Bryan and Lewis, 1979, vertical diffusivity profile
36    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
37    o added Sadourny discretization of Coriolis
38      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
39      - re-enabled use of omega3 (useAbsVorticity)
40    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
41      vector-invariant equations
42      - note: does *NOT* yet use same variable visc. for no-slip BC's.
43    o recoded the lateral boundary conditions for non-hydrostatic w, this time
44      hopefully without new bugs
45      - still to do: biharmonic friction for non-hydrostatic w
46    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
47    o regenerated output for global_ocean_ebm (using -ieee)
48    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
49      of mom_common/
50      - simple re-arrangement of instructions within computing loop
51    checkpoint53d_pre
52    
53    checkpoint53c_post
54    o new version of coupler for AIM+thSIce and Ocean models
55     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
56     - land: change Evaporation of snow
57     - aim with thSIce: fix bug in snow-precip.
58    o changes to calc_gw.F
59     - bug fix for w^2 term near the bottom boundary
60     - (hopefully) improve the lateral slip boundary condtions for use with
61        partial/looped cells
62      - because the bug fix changes two verification experiments anyway (exp5
63        and plume on slope), change the lateral boundary condition from half slip
64        to the value of no_slip_sides
65    o ebm package wasnt quite up to the parallel task. Fixed that.
66    o Adjoint of EBM package + verification
67      * TLM OK
68      * ADM not sufficient accuracy yet (needs further testing)
69    
70    checkpoint53b_post
71    o Commiting new energy balance model to repository
72      * package is pkg/ebm
73      * verif. is verification/global_ocean_ebm
74      * references are in ebm_driver.F
75    C      * X. Wang, P. Stone and J. Marotzke, 1999:
76    C        Global thermohaline circulation. Part I:
77    C        Sensitivity to atmospheric moisture transport.
78    C        J. Climate 12(1), 71-82
79    C      * X. Wang, P. Stone and J. Marotzke, 1999:
80    C        Global thermohaline circulation. Part II:
81    C        Sensitivity with interactive transport.
82    C        J. Climate 12(1), 83-91
83    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
84    C        Destabilization of the thermohaline circulation
85    C        by atmospheric eddy transports.
86    C        J. Climate 7(12), 1870-1882
87    o Will need long integration testing.
88    checkpoint53b_pre
89    
90    o created pkg/mom_common in preparation for variable viscosity code
91    o renamed and split ini_mnc_io
92    o pkg/land: only liquid water can diffuse or run-off
93    o AIM using land: soil wetness availability account for snow
94    o added printMapIncludesZeros to EEPARMS namelist
95    
96    checkpoint53a_post
97    o restore TAMC compatiility for exf_constants.h
98      (no usage of _d in .h)
99    o Additional storing in KPP in an attempt to fix
100      TAMC problem with adjoint of KPP code.
101      (no success...)
102      Identical code works fine with TAF.
103    o Fixed verification/natl_box_adjoint experiments.
104      Initial conditions for Experiments 4 and 5 are now
105      set to "SEAICE_initialHEFF=0", which is more reasonable,
106      and hence gives results closer to that of Experiment 2.
107      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
108    
109    checkpoint53
110    o stable checkpoint with up to date adjoint
111      TLM tests only run for 1st grdchk at the moment. Its unclear if
112      this is a code problem or a problem with resetting code for g_
113      variables that is being autogenerated wrong.
114      Otherwise:
115       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
116       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
117         are both still in chaos following their security messes.
118    
119    checkpoint52n_post
120    o various build (mostly genmake2) changes including:
121      - ability to build/run more easily within Cygwin and MacOS X
122      - more complicated Makefiles with a stronger dependence on Gnu Make
123    o pkg/seaice modifications
124      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
125        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
126        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
127      - changed proxy for geostrophic velocity and updated
128        verification/lab_sea/results/* accordingly
129      - removed ADI dynamic solver from pkg/seaice
130      - replaced all occurrences of 1/CSTICE or 1/CSUICE
131        they caused a segmentation fault under certain circumstances
132      - removed unused field WATR
133    o bug fix in exf-package:
134      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
135         now reflect that.
136    o small fixes in the cal-package:
137      - set reference date to first of January for the 'model'-calendar
138      - failing of cal_CheckDate in cal_FullDate now actually results in a
139        warning
140    o small modifications in exf-package to increase flexibility:
141      - change climtempfreeze from a constant to a runtime parameter that
142        is specified in data.exf_clim (default = -1.9)
143      - introduce runtime parameter windstressmax (default = 2.0) that is
144        specified in data.exf
145    o fix in pkg/thsice:
146      - update Evap (Tsf changes) to be consistent with Latent heat flux
147      - maintain snow precipitation unchanged (even if Tsf >=0).
148     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
149    
150    checkpoint52m_post
151    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
152      this does not change any of the results, because myIter=0 in swfrac always
153      lead to jwtype=2 (the default anyway), but the call makes little sense
154      as a default
155    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
156    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
157      atmospheric model (AIM) to use it ; add a "slab ocean" component.
158    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
159    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
160    o extending useSingleCpuIO option to work with new exch2 I/O format
161      - old-style, missing-tile I/O is still accessible by defining CPP
162        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
163    o monitor package can write to NetCDF files and/or STDOUT
164    o fix re-definition bug in MNC_GRID_INIT_ALL()
165    o doc/api_reference added
166      - a framework for building an API Reference Manual using all
167        the "protex" comments embedded in the code
168      - see pkg/generic_advdiff, pkg/mnc for examples
169    o MNC:
170      - make myThid the last argument for all subroutines
171      - new default for the grid files: NO halos
172      - add useMNC and other run-time flags
173      - separate per-file-group handling of the unlimited dimension
174      - early initialization of MNC w/ flags read at the eeboot stage
175        and lookup tables set in initialize_fixed
176      - write all MNC output to a freshly-created directory
177    o thermodynamics sea-ice (thsice) is now tested with testreport.
178    o test exp. advect_cs: use the standard cs32 grid ; update output.
179    o Added functionality to grdchk:
180      pick global i,j,k position (or nearest wet) where to perform check.
181    
182    checkpoint52l_post
183    o new land formulation:
184      a) use ground enthalpy as prognostic variable to ensure exact
185         energy conservation.
186      b) account for water temperature and for latent heat of freezing
187         in all processes (rain, run-off, ground storage)
188      c) compute surface and ground temperature implicitly.
189    o aim_v23 modification for new land model:
190      a) Treat separately land / ocean / sea-ice surface fluxes
191         to allow implicit computation of land & sea-ice surface temp.
192      b) add snow precipitation.
193    checkpoint52l_pre
194    
195    o fix problem (when 1 tile is empty) in min/max monitor.
196    o fix bug in timeAve (u,vZetatave in common block)
197    o no restoring terms under ice for pkg/seaice
198    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
199    o bug fix for pkg/seaice pickups
200    o change MNC call locations and add coordinate attributes
201    o mask vorticity at the corner ; affects global_ocean.cs output
202    o fix ini_curvilinear_grid ; test CS experiments with mpi
203    o aim.5l_cs: modify sea-ice fraction input file ; update output
204    o exf: Adding simple range check routine for exf fields after read
205    
206    checkpoint52k_post
207    o removed top-level directory "diags"
208      - we migrated these functions to pkg/timeave a long time ago
209    o fixed bug introduced in pkg/monitor
210    o accuracy ctrlprec = 32 insuffient for gradient checks using
211      averaged fields (I/O via cost_averages)
212      -> use ctrl.h in active_file*.F to control I/O precision.
213    o paramter list of CALL ADTHE_MAIN_LOOP
214    o added initial do_the_model_io to ecco
215    o set all ...Freq to zero after cost_final
216      taveFreq, dumpFreq, pChkptFreq
217    o MAIN and ECCO differentiability restored
218    
219    checkpoint52j_post
220    o fix nchklev in tamc.h for global_ocean...
221    o Bringing flow and store directives up-to-date
222    o Really weird thing!
223      call do_the_model_io from the_main_loop with parameters
224      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
225      TAF places a faulty re-call of initialise_varia
226      after cost_final call which should not be there!
227    checkpoint52j_pre
228    
229    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
230      error messages
231    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
232    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
233      debug output
234    o modfied mdsio_writefield.F to handle non-global files under exch2
235    o update AIM Cubed-Sphere exp (aim.5l_cs):
236      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
237    o update AIM Equatorial Channel exp:
238      use standard aim_v23 pkg and change the SST fields to be more realistic.
239    o globalFile now works with exch2
240    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
241      mon_vort3.F to make exch2 friendly with >1 tile per cube face
242    o limit timeave output for hi-res integrations
243    
244    checkpoint52i_post
245    o removed CPP_EEOPTIONS.h from verification/*/code
246    o updated the tiling for global_ocean_pressure
247    checkpoint52i_pre
248    
249    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
250      the old pkg/aim).
251    
252    checkpoint52h_pre
253    o shortened offending lines in exch2_send_rx?.template
254    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
255    o genmake2: add build & execute test for NetCDF code
256    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
257      old grid files, moved CPP_EEMACROS.h to pkg/exch2
258    o added useSingleCPUIO flag to monitor.F and mon_out.F
259    o added temporary hack for sea-ice dynamics on the cube:
260      metric terms are ignored and it is assumed that
261      there is no sea-ice on cube faces 1, 2, 4, and 5.
262    
263    checkpoint52f_post
264    o added exch2 cube routines to pkg/exch2
265    o modified hs94.cs-32x32x5 to use it
266    o added new grid files to hs94.cs-32x32x5
267    checkpoint52f_pre
268    
269    checkpoint52e_post
270    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
271      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
272    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
273      to work with implicit vertical advection and AB ;
274    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
275    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
276     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
277    checkpoint52e_pre
278    
279    o fix bug in impldiff when Nr=1 or Nr=2.
280    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
281    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
282    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
283      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
284    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
285    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
286    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
287    
288    checkpoint52d_post
289    o re-tiled many expts to allow comparison in multi-processor mode
290      - updated output accordingly
291      - changed hs94.128x64x5 to use intial T from file rather than use the
292        random number generator
293    o add infrastructure in model routines for fizhi and gridalt packages
294    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
295    o changes to permit hi-res, cubed-sphere, configuration
296      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
297      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
298      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
299        of surface winds for the cube
300      (A verification experiment, based on global_ocean.cs32x15, but with
301       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
302       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
303       complete with example surface forcing files and matlab scripts to look
304       at the output and compare it with that of global_ocean.cs32x15.)
305    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
306       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
307       to conform to the common rule.
308    o check-in the first version of the coupler + interfaces for multi-components
309       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
310       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
311       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
312       - ocean and atmos. share the same horizontal grid (no interpolation).
313       - exchanges between component and coupler is done in forward_step
314    o new verification experiment, cpl_aim+ocn:
315       coupled ocean - AIM atmosphere on cs32 grid.
316    
317    checkpoint52d_pre
318    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
319    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
320    
321    checkpoint52c_post
322    o Fixing OPTIONS files for use of exf:
323      - ALLOW_ECCO not needed
324      - ECCO_CPPOPTIONS.h should not be included from
325        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
326        as has been the case in the past
327      - All cal/exf related options are currently set in
328        single header file. Should remain so until we
329        agree on a consistent new policy.
330    o Removed all CPP options for cal package.
331      cal has no more CPP options.
332    o modified STOREs in GAD_ADVECTION
333    o corrected key comp. for passkey
334    
335    checkpoint52b_post
336    o new version: "thsice" of thermodynamic sea-ice pkg:
337     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
338     - modify fluxes but do not change theta directly;
339     - light cleaning of bulk_force pkg (still needed with thsice).
340     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
341       + output_thsice.txt to test thsice & bulk_force pkgs.
342    o put back grid & coriolis monitor output.
343    checkpoint52b_pre
344    
345    o call "do_the_model_io" at the beginning (=> dump initial state)
346    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
347    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
348      (need info on NUMBER_OF_PTRACERS)
349    o missing PTRACERS headers in some routines
350    o default tamc.h in pkg/autodiff supposed to crash
351      to ensure proper customization
352    
353    checkpoint52a_post
354    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
355      - moved surfaceTendencyTice from pkg/seaice to main code
356      - subroutine FREEZE_SURFACE now limits only surface temperature
357        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
358        => new output.txt for global_ocean.cs32x15 & global_with_exf
359      - keep the old version of FREEZE for backward compatibility;
360        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
361      - corresponding modifs for TAF directives
362    o added surface flux output variables to TIMEAVE_STATVARS
363    o time-averaged output for pkg/ptracers
364    o fix problem with ECCO-related divided adjoint
365      snapshot file was missing some ad-variables,
366      but no warning issued by TAF
367    
368    checkpoint52a_pre
369    o some bug fixes for #undef REAL4_IS_SLOW
370    
371    checkpoint52 = ecco_c52_e35
372    o after testing adjoints of checkpoint51u_post
373    
374    checkpoint51u_post
375    o this is the post-merge tag of the ecco-branch
376      (needs another clean checkout and re-testing)
377    o various natl_box_adjoint configs and results
378      but no input fields
379    o obcs adjoint not yet merged!
380    o adding ECCO global 1x1 and 2x2 degree configs
381    o updated/extended some store directives for seaice
382    o pkg/ecco now containes ecco-specific part of cost function
383    o top level routines the_main_loop, forward_step
384      supersede those in model/src/
385      previous input data.cost now in data.ecco
386      (new namelist ecco_cost_nml)
387    o in ctrl/ cleaned some cross-dependencies and updated CPP options
388    
389    checkpoint51t_post
390    o this is the pre-merge tag of the ecco-branch
391    
392    checkpoint51s_post
393    o cleanup: removed various obsolete #define-s
394    o pkg/grdchk
395      - renamed 'ph-grd 3' to 'grad-res'
396      - merged from ecco-branch
397        (remaining bug fixes for obcs gradient checks)
398      - additional high-precision output for testreport
399        (grep for 'precision_grdchk_result')

401    checkpoint51r_post
402    o cleaned up or removed CPP_OPTIONS.h files
403    o updated results for some of the tests to reflect the new
404      optfiles (-ieee: -O0 instead of -O3)
405    
406    checkpoint51q_post
407    o cd_code:
408      - moved cd_scheme.F -> cd_code_scheme.F
409      - separate read_checkpoint from cd_code_ini_vars.F
410      - separated cd_code part from write_checkpoint
411      - updated AD_SOURCE, generated .flow
412      - added CD_CODE_VARS.h to the_main_loop
413      - Moving cd_code specific store dir.s to pkg/cd_code
414    o ctrl package totally restructured
415      - pack/unpack now optional and decoupled from
416        xx_/adxx_ I/O
417      - ctrl_pack/unpack cleaned
418        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
419      - confined inclusion of AD_CONFIG.h to where necessary.
420    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
421    
422    checkpoint51p_post
423    o create initial cd_code package
424      - WARNING: the initialization of fields within packages
425        is broken because INI_FIELDS (where READ_CHECKPOINT is
426        called) is called *before* PACKAGES_INIT_VARIABLES.
427        This seems to be backwards since
428        1) its important to initially zero the entire field including
429           the "halo" region
430        2) zeroing needs to be done *before* reading pickup info
431           and the pickup call might or might not happen in any
432           particular run
433      - this needs an overhaul for R2
434    o cleanup verification/*/code/GMREDI_OPTIONS.h
435    o cleanup testreport
436    
437    checkpoint51o_post
438    o bringing AD-related verif's up to date with genmake2
439      - carbon/
440      - global_ocean.90x40x15/
441      - hs.94.1x64x5/
442      - (front_relax/ )
443    o (more) consistent directory structure for AD-related verif.'s
444    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
445    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
446    o bug fix in find_alpha.F for MDJWF:
447      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
448        change rho -> rho-rhoConst
449      - replace call find_rho to find_rhonum
450    o initialisation of rFlx extended to full array (required by TAF)
451      and shifted to thermodynamics
452    o removed PTRACERS.h in ptracers routine
453    o added surfacetendencyPtr to S/R parameter list pracers_forcing
454    o Correcting initialisations for fVerU, fVerV.
455    o helping TAF to recognize dependency on kUp for
456      fVerU, fVerV
457    o Replacing delZ by delR in pkg/ctrl/
458    checkpoint51o_pre
459    
460    o undid all of cp51 pending some cleanups and discussion
461    o added the [#include "AD_CONFIG.h"] statement to all files that need
462       it for adjoint/tl #defines
463     o re-worked the build logic in genmake2 to support AD_CONFIG.h
464     o removed tools/genmake since it no longer works
465    
466  checkpoint51n_post  checkpoint51n_post
467  o modifications to make FREEZE flux visible to pkg/kpp  o modifications to make FREEZE flux visible to pkg/kpp
