3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6  untagged  
7    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
8      vector-invarianet equations
9      - note: does *NOT* yet use same variable visc. for no-slip BC's.
10    o recoded the lateral boundary conditions for non-hydrostatic w, this time
11      hopefully without new bugs
12      - still to do: biharmonic friction for non-hydrostatic w
13    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
14    o regenerated output for global_ocean_ebm (using -ieee)
15    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
16      of mom_common/
17      - simple re-arrangement of instructions within computing loop
18    checkpoint53d_pre
19    
20    checkpoint53c_post
21    o new version of coupler for AIM+thSIce and Ocean models
22     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
23     - land: change Evaporation of snow
24     - aim with thSIce: fix bug in snow-precip.
25    o changes to calc_gw.F
26     - bug fix for w^2 term near the bottom boundary
27     - (hopefully) improve the lateral slip boundary condtions for use with
28        partial/looped cells
29      - because the bug fix changes two verification experiments anyway (exp5
30        and plume on slope), change the lateral boundary condition from half slip
31        to the value of no_slip_sides
32    o ebm package wasnt quite up to the parallel task. Fixed that.
33    o Adjoint of EBM package + verification
34      * TLM OK
35      * ADM not sufficient accuracy yet (needs further testing)
36    
37    checkpoint53b_post
38    o Commiting new energy balance model to repository
39      * package is pkg/ebm
40      * verif. is verification/global_ocean_ebm
41      * references are in ebm_driver.F
42    C      * X. Wang, P. Stone and J. Marotzke, 1999:
43    C        Global thermohaline circulation. Part I:
44    C        Sensitivity to atmospheric moisture transport.
45    C        J. Climate 12(1), 71-82
46    C      * X. Wang, P. Stone and J. Marotzke, 1999:
47    C        Global thermohaline circulation. Part II:
48    C        Sensitivity with interactive transport.
49    C        J. Climate 12(1), 83-91
50    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
51    C        Destabilization of the thermohaline circulation
52    C        by atmospheric eddy transports.
53    C        J. Climate 7(12), 1870-1882
54    o Will need long integration testing.
55    checkpoint53b_pre
56    
57    o created pkg/mom_common in preparation for variable viscosity code
58    o renamed and split ini_mnc_io
59    o pkg/land: only liquid water can diffuse or run-off
60    o AIM using land: soil wetness availability account for snow
61    o added printMapIncludesZeros to EEPARMS namelist
62    
63    checkpoint53a_post
64    o restore TAMC compatiility for exf_constants.h
65      (no usage of _d in .h)
66    o Additional storing in KPP in an attempt to fix
67      TAMC problem with adjoint of KPP code.
68      (no success...)
69      Identical code works fine with TAF.
70    o Fixed verification/natl_box_adjoint experiments.
71      Initial conditions for Experiments 4 and 5 are now
72      set to "SEAICE_initialHEFF=0", which is more reasonable,
73      and hence gives results closer to that of Experiment 2.
74      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
75    
76    checkpoint53
77    o stable checkpoint with up to date adjoint
78      TLM tests only run for 1st grdchk at the moment. Its unclear if
79      this is a code problem or a problem with resetting code for g_
80      variables that is being autogenerated wrong.
81      Otherwise:
82       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
83       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
84         are both still in chaos following their security messes.
85    
86    checkpoint52n_post
87    o various build (mostly genmake2) changes including:
88      - ability to build/run more easily within Cygwin and MacOS X
89      - more complicated Makefiles with a stronger dependence on Gnu Make
90    o pkg/seaice modifications
91      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
92        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
93        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
94      - changed proxy for geostrophic velocity and updated
95        verification/lab_sea/results/* accordingly
96      - removed ADI dynamic solver from pkg/seaice
97      - replaced all occurrences of 1/CSTICE or 1/CSUICE
98        they caused a segmentation fault under certain circumstances
99      - removed unused field WATR
100    o bug fix in exf-package:
101      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
102         now reflect that.
103    o small fixes in the cal-package:
104      - set reference date to first of January for the 'model'-calendar
105      - failing of cal_CheckDate in cal_FullDate now actually results in a
106        warning
107    o small modifications in exf-package to increase flexibility:
108      - change climtempfreeze from a constant to a runtime parameter that
109        is specified in data.exf_clim (default = -1.9)
110      - introduce runtime parameter windstressmax (default = 2.0) that is
111        specified in data.exf
112    o fix in pkg/thsice:
113      - update Evap (Tsf changes) to be consistent with Latent heat flux
114      - maintain snow precipitation unchanged (even if Tsf >=0).
115     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
116    
117    checkpoint52m_post
118    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
119      this does not change any of the results, because myIter=0 in swfrac always
120      lead to jwtype=2 (the default anyway), but the call makes little sense
121      as a default
122    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
123    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
124      atmospheric model (AIM) to use it ; add a "slab ocean" component.
125    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
126    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
127    o extending useSingleCpuIO option to work with new exch2 I/O format
128      - old-style, missing-tile I/O is still accessible by defining CPP
129        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
130    o monitor package can write to NetCDF files and/or STDOUT
131    o fix re-definition bug in MNC_GRID_INIT_ALL()
132    o doc/api_reference added
133      - a framework for building an API Reference Manual using all
134        the "protex" comments embedded in the code
135      - see pkg/generic_advdiff, pkg/mnc for examples
136    o MNC:
137      - make myThid the last argument for all subroutines
138      - new default for the grid files: NO halos
139      - add useMNC and other run-time flags
140      - separate per-file-group handling of the unlimited dimension
141      - early initialization of MNC w/ flags read at the eeboot stage
142        and lookup tables set in initialize_fixed
143      - write all MNC output to a freshly-created directory
144    o thermodynamics sea-ice (thsice) is now tested with testreport.
145    o test exp. advect_cs: use the standard cs32 grid ; update output.
146    o Added functionality to grdchk:
147      pick global i,j,k position (or nearest wet) where to perform check.
148    
149    checkpoint52l_post
150    o new land formulation:
151      a) use ground enthalpy as prognostic variable to ensure exact
152         energy conservation.
153      b) account for water temperature and for latent heat of freezing
154         in all processes (rain, run-off, ground storage)
155      c) compute surface and ground temperature implicitly.
156    o aim_v23 modification for new land model:
157      a) Treat separately land / ocean / sea-ice surface fluxes
158         to allow implicit computation of land & sea-ice surface temp.
159      b) add snow precipitation.
160    checkpoint52l_pre
161    
162    o fix problem (when 1 tile is empty) in min/max monitor.
163    o fix bug in timeAve (u,vZetatave in common block)
164    o no restoring terms under ice for pkg/seaice
165    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
166    o bug fix for pkg/seaice pickups
167    o change MNC call locations and add coordinate attributes
168    o mask vorticity at the corner ; affects global_ocean.cs output
169    o fix ini_curvilinear_grid ; test CS experiments with mpi
170    o aim.5l_cs: modify sea-ice fraction input file ; update output
171    o exf: Adding simple range check routine for exf fields after read
172    
173    checkpoint52k_post
174    o removed top-level directory "diags"
175      - we migrated these functions to pkg/timeave a long time ago
176    o fixed bug introduced in pkg/monitor
177    o accuracy ctrlprec = 32 insuffient for gradient checks using
178      averaged fields (I/O via cost_averages)
179      -> use ctrl.h in active_file*.F to control I/O precision.
180    o paramter list of CALL ADTHE_MAIN_LOOP
181    o added initial do_the_model_io to ecco
182    o set all ...Freq to zero after cost_final
183      taveFreq, dumpFreq, pChkptFreq
184    o MAIN and ECCO differentiability restored
185    
186    checkpoint52j_post
187    o fix nchklev in tamc.h for global_ocean...
188    o Bringing flow and store directives up-to-date
189    o Really weird thing!
190      call do_the_model_io from the_main_loop with parameters
191      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
192      TAF places a faulty re-call of initialise_varia
193      after cost_final call which should not be there!
194    checkpoint52j_pre
195    
196    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
197      error messages
198    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
199    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
200      debug output
201    o modfied mdsio_writefield.F to handle non-global files under exch2
202    o update AIM Cubed-Sphere exp (aim.5l_cs):
203      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
204    o update AIM Equatorial Channel exp:
205      use standard aim_v23 pkg and change the SST fields to be more realistic.
206    o globalFile now works with exch2
207    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
208      mon_vort3.F to make exch2 friendly with >1 tile per cube face
209    o limit timeave output for hi-res integrations
210    
211    checkpoint52i_post
212    o removed CPP_EEOPTIONS.h from verification/*/code
213    o updated the tiling for global_ocean_pressure
214    checkpoint52i_pre
215    
216    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
217      the old pkg/aim).
218    
219    checkpoint52h_pre
220    o shortened offending lines in exch2_send_rx?.template
221    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
222    o genmake2: add build & execute test for NetCDF code
223    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
224      old grid files, moved CPP_EEMACROS.h to pkg/exch2
225    o added useSingleCPUIO flag to monitor.F and mon_out.F
226    o added temporary hack for sea-ice dynamics on the cube:
227      metric terms are ignored and it is assumed that
228      there is no sea-ice on cube faces 1, 2, 4, and 5.
229    
230    checkpoint52f_post
231    o added exch2 cube routines to pkg/exch2
232    o modified hs94.cs-32x32x5 to use it
233    o added new grid files to hs94.cs-32x32x5
234    checkpoint52f_pre
235    
236    checkpoint52e_post
237    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
238      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
239    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
240      to work with implicit vertical advection and AB ;
241    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
242    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
243     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
244    checkpoint52e_pre
245    
246    o fix bug in impldiff when Nr=1 or Nr=2.
247    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
248    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
249    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
250      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
251    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
252    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
253    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
254    
255    checkpoint52d_post
256    o re-tiled many expts to allow comparison in multi-processor mode
257      - updated output accordingly
258      - changed hs94.128x64x5 to use intial T from file rather than use the
259        random number generator
260    o add infrastructure in model routines for fizhi and gridalt packages
261    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
262    o changes to permit hi-res, cubed-sphere, configuration
263      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
264      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
265      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
266        of surface winds for the cube
267      (A verification experiment, based on global_ocean.cs32x15, but with
268       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
269       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
270       complete with example surface forcing files and matlab scripts to look
271       at the output and compare it with that of global_ocean.cs32x15.)
272    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
273       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
274       to conform to the common rule.
275    o check-in the first version of the coupler + interfaces for multi-components
276       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
277       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
278       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
279       - ocean and atmos. share the same horizontal grid (no interpolation).
280       - exchanges between component and coupler is done in forward_step
281    o new verification experiment, cpl_aim+ocn:
282       coupled ocean - AIM atmosphere on cs32 grid.
283    
284    checkpoint52d_pre
285    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
286    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
287    
288    checkpoint52c_post
289    o Fixing OPTIONS files for use of exf:
290      - ALLOW_ECCO not needed
291      - ECCO_CPPOPTIONS.h should not be included from
292        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
293        as has been the case in the past
294      - All cal/exf related options are currently set in
295        single header file. Should remain so until we
296        agree on a consistent new policy.
297    o Removed all CPP options for cal package.
298      cal has no more CPP options.
299    o modified STOREs in GAD_ADVECTION
300    o corrected key comp. for passkey
301    
302    checkpoint52b_post
303    o new version: "thsice" of thermodynamic sea-ice pkg:
304     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
305     - modify fluxes but do not change theta directly;
306     - light cleaning of bulk_force pkg (still needed with thsice).
307     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
308       + output_thsice.txt to test thsice & bulk_force pkgs.
309    o put back grid & coriolis monitor output.
310    checkpoint52b_pre
311    
312    o call "do_the_model_io" at the beginning (=> dump initial state)
313    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
314    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
315      (need info on NUMBER_OF_PTRACERS)
316    o missing PTRACERS headers in some routines
317    o default tamc.h in pkg/autodiff supposed to crash
318      to ensure proper customization
319    
320    checkpoint52a_post
321    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
322      - moved surfaceTendencyTice from pkg/seaice to main code
323      - subroutine FREEZE_SURFACE now limits only surface temperature
324        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
325        => new output.txt for global_ocean.cs32x15 & global_with_exf
326      - keep the old version of FREEZE for backward compatibility;
327        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
328      - corresponding modifs for TAF directives
329    o added surface flux output variables to TIMEAVE_STATVARS
330    o time-averaged output for pkg/ptracers
331    o fix problem with ECCO-related divided adjoint
332      snapshot file was missing some ad-variables,
333      but no warning issued by TAF
334    
335    checkpoint52a_pre
336    o some bug fixes for #undef REAL4_IS_SLOW
337    
338    checkpoint52 = ecco_c52_e35
339    o after testing adjoints of checkpoint51u_post
340    
341    checkpoint51u_post
342    o this is the post-merge tag of the ecco-branch
343      (needs another clean checkout and re-testing)
344    o various natl_box_adjoint configs and results
345      but no input fields
346    o obcs adjoint not yet merged!
347    o adding ECCO global 1x1 and 2x2 degree configs
348    o updated/extended some store directives for seaice
349    o pkg/ecco now containes ecco-specific part of cost function
350    o top level routines the_main_loop, forward_step
351      supersede those in model/src/
352      previous input data.cost now in data.ecco
353      (new namelist ecco_cost_nml)
354    o in ctrl/ cleaned some cross-dependencies and updated CPP options
355    
356    checkpoint51t_post
357    o this is the pre-merge tag of the ecco-branch
358    
359    checkpoint51s_post
360    o cleanup: removed various obsolete #define-s
361    o pkg/grdchk
362      - renamed 'ph-grd 3' to 'grad-res'
363      - merged from ecco-branch
364        (remaining bug fixes for obcs gradient checks)
365      - additional high-precision output for testreport
366        (grep for 'precision_grdchk_result')
367    
368    checkpoint51r_post
369    o cleaned up or removed CPP_OPTIONS.h files
370    o updated results for some of the tests to reflect the new
371      optfiles (-ieee: -O0 instead of -O3)
372    
373    checkpoint51q_post
374    o cd_code:
375      - moved cd_scheme.F -> cd_code_scheme.F
376      - separate read_checkpoint from cd_code_ini_vars.F
377      - separated cd_code part from write_checkpoint
378      - updated AD_SOURCE, generated .flow
379      - added CD_CODE_VARS.h to the_main_loop
380      - Moving cd_code specific store dir.s to pkg/cd_code
381    o ctrl package totally restructured
382      - pack/unpack now optional and decoupled from
383        xx_/adxx_ I/O
384      - ctrl_pack/unpack cleaned
385        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
386      - confined inclusion of AD_CONFIG.h to where necessary.
387    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
388    
389    checkpoint51p_post
390    o create initial cd_code package
391      - WARNING: the initialization of fields within packages
392        is broken because INI_FIELDS (where READ_CHECKPOINT is
393        called) is called *before* PACKAGES_INIT_VARIABLES.
394        This seems to be backwards since
395        1) its important to initially zero the entire field including
396           the "halo" region
397        2) zeroing needs to be done *before* reading pickup info
398           and the pickup call might or might not happen in any
399           particular run
400      - this needs an overhaul for R2
401    o cleanup verification/*/code/GMREDI_OPTIONS.h
402    o cleanup testreport
403    
404    checkpoint51o_post
405    o bringing AD-related verif's up to date with genmake2
406      - carbon/
407      - global_ocean.90x40x15/
408      - hs.94.1x64x5/
409      - (front_relax/ )
410    o (more) consistent directory structure for AD-related verif.'s
411    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
412    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
413    o bug fix in find_alpha.F for MDJWF:
414      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
415        change rho -> rho-rhoConst
416      - replace call find_rho to find_rhonum
417    o initialisation of rFlx extended to full array (required by TAF)
418      and shifted to thermodynamics
419    o removed PTRACERS.h in ptracers routine
420    o added surfacetendencyPtr to S/R parameter list pracers_forcing
421    o Correcting initialisations for fVerU, fVerV.
422    o helping TAF to recognize dependency on kUp for
423      fVerU, fVerV
424    o Replacing delZ by delR in pkg/ctrl/
425    checkpoint51o_pre
426    
427    o undid all of cp51 pending some cleanups and discussion
428    o added the [#include "AD_CONFIG.h"] statement to all files that need
429       it for adjoint/tl #defines
430     o re-worked the build logic in genmake2 to support AD_CONFIG.h
431     o removed tools/genmake since it no longer works
432    
433    checkpoint51n_post
434    o modifications to make FREEZE flux visible to pkg/kpp
435      - moved surfaceTendencyTice from pkg/seaice to main code
436      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
437      - subroutine FREEZE now limits only surface temperature
438        (this means new output.txt for global_ocean.90x40x15,
439         global_ocean.cs32x15, and global_with_exf)
440    o added surface flux output variables to TIMEAVE_STATVARS
441    
442    checkpoint51n_pre
443  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F  o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
444  o added [#include "AD_CONFIG.h"] to all files that use the following  o added [#include "AD_CONFIG.h"] to all files that use the following
