3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o prepare splitting of thermodynamics: store convect.counter in common block
7    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
8      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
9    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
10    o new parameter "nShapS": allow to treat differently S from T (nShapT)
11    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
12    
13    checkpoint53f_post
14    o modifications that affect AIM experiment results (update output.txt):
15      - no advection of S at top interface Nr (pkg/generic_advdiff)
16      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
17    o AIM pkg:
18      - include stability function into surf.Flux derivative relative to Tsurf
19      - calculate clear-sky radiation & surface temp. change (for diagnostics)
20    
21    checkpoint53e_post
22    o merged cylindrical coord configuration
23    o added rotating_tank experiment
24    checkpoint53e_pre
25    
26    checkpoint53d_post
27    o faulks upgraded: re-generate output.txt that have changed:
28       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
29    o Added Bryan and Lewis, 1979, vertical diffusivity profile
30    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
31    o added Sadourny discretization of Coriolis
32      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
33      - re-enabled use of omega3 (useAbsVorticity)
34    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
35      vector-invariant equations
36      - note: does *NOT* yet use same variable visc. for no-slip BC's.
37    o recoded the lateral boundary conditions for non-hydrostatic w, this time
38      hopefully without new bugs
39      - still to do: biharmonic friction for non-hydrostatic w
40    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
41    o regenerated output for global_ocean_ebm (using -ieee)
42    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
43      of mom_common/
44      - simple re-arrangement of instructions within computing loop
45    checkpoint53d_pre
46    
47    checkpoint53c_post
48    o new version of coupler for AIM+thSIce and Ocean models
49     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
50     - land: change Evaporation of snow
51     - aim with thSIce: fix bug in snow-precip.
52    o changes to calc_gw.F
53     - bug fix for w^2 term near the bottom boundary
54     - (hopefully) improve the lateral slip boundary condtions for use with
55        partial/looped cells
56      - because the bug fix changes two verification experiments anyway (exp5
57        and plume on slope), change the lateral boundary condition from half slip
58        to the value of no_slip_sides
59    o ebm package wasnt quite up to the parallel task. Fixed that.
60    o Adjoint of EBM package + verification
61      * TLM OK
62      * ADM not sufficient accuracy yet (needs further testing)
63    
64    checkpoint53b_post
65    o Commiting new energy balance model to repository
66      * package is pkg/ebm
67      * verif. is verification/global_ocean_ebm
68      * references are in ebm_driver.F
69    C      * X. Wang, P. Stone and J. Marotzke, 1999:
70    C        Global thermohaline circulation. Part I:
71    C        Sensitivity to atmospheric moisture transport.
72    C        J. Climate 12(1), 71-82
73    C      * X. Wang, P. Stone and J. Marotzke, 1999:
74    C        Global thermohaline circulation. Part II:
75    C        Sensitivity with interactive transport.
76    C        J. Climate 12(1), 83-91
77    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
78    C        Destabilization of the thermohaline circulation
79    C        by atmospheric eddy transports.
80    C        J. Climate 7(12), 1870-1882
81    o Will need long integration testing.
82    checkpoint53b_pre
83    
84    o created pkg/mom_common in preparation for variable viscosity code
85    o renamed and split ini_mnc_io
86    o pkg/land: only liquid water can diffuse or run-off
87    o AIM using land: soil wetness availability account for snow
88    o added printMapIncludesZeros to EEPARMS namelist
89    
90    checkpoint53a_post
91    o restore TAMC compatiility for exf_constants.h
92      (no usage of _d in .h)
93    o Additional storing in KPP in an attempt to fix
94      TAMC problem with adjoint of KPP code.
95      (no success...)
96      Identical code works fine with TAF.
97    o Fixed verification/natl_box_adjoint experiments.
98      Initial conditions for Experiments 4 and 5 are now
99      set to "SEAICE_initialHEFF=0", which is more reasonable,
100      and hence gives results closer to that of Experiment 2.
101      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
102    
103    checkpoint53
104    o stable checkpoint with up to date adjoint
105      TLM tests only run for 1st grdchk at the moment. Its unclear if
106      this is a code problem or a problem with resetting code for g_
107      variables that is being autogenerated wrong.
108      Otherwise:
109       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
110       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
111         are both still in chaos following their security messes.
112    
113    checkpoint52n_post
114    o various build (mostly genmake2) changes including:
115      - ability to build/run more easily within Cygwin and MacOS X
116      - more complicated Makefiles with a stronger dependence on Gnu Make
117    o pkg/seaice modifications
118      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
119        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
120        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
121      - changed proxy for geostrophic velocity and updated
122        verification/lab_sea/results/* accordingly
123      - removed ADI dynamic solver from pkg/seaice
124      - replaced all occurrences of 1/CSTICE or 1/CSUICE
125        they caused a segmentation fault under certain circumstances
126      - removed unused field WATR
127    o bug fix in exf-package:
128      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
129         now reflect that.
130    o small fixes in the cal-package:
131      - set reference date to first of January for the 'model'-calendar
132      - failing of cal_CheckDate in cal_FullDate now actually results in a
133        warning
134    o small modifications in exf-package to increase flexibility:
135      - change climtempfreeze from a constant to a runtime parameter that
136        is specified in data.exf_clim (default = -1.9)
137      - introduce runtime parameter windstressmax (default = 2.0) that is
138        specified in data.exf
139    o fix in pkg/thsice:
140      - update Evap (Tsf changes) to be consistent with Latent heat flux
141      - maintain snow precipitation unchanged (even if Tsf >=0).
142     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
143    
144    checkpoint52m_post
145    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
146      this does not change any of the results, because myIter=0 in swfrac always
147      lead to jwtype=2 (the default anyway), but the call makes little sense
148      as a default
149    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
150    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
151      atmospheric model (AIM) to use it ; add a "slab ocean" component.
152    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
153    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
154    o extending useSingleCpuIO option to work with new exch2 I/O format
155      - old-style, missing-tile I/O is still accessible by defining CPP
156        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
157    o monitor package can write to NetCDF files and/or STDOUT
158    o fix re-definition bug in MNC_GRID_INIT_ALL()
159    o doc/api_reference added
160      - a framework for building an API Reference Manual using all
161        the "protex" comments embedded in the code
162      - see pkg/generic_advdiff, pkg/mnc for examples
163    o MNC:
164      - make myThid the last argument for all subroutines
165      - new default for the grid files: NO halos
166      - add useMNC and other run-time flags
167      - separate per-file-group handling of the unlimited dimension
168      - early initialization of MNC w/ flags read at the eeboot stage
169        and lookup tables set in initialize_fixed
170      - write all MNC output to a freshly-created directory
171    o thermodynamics sea-ice (thsice) is now tested with testreport.
172    o test exp. advect_cs: use the standard cs32 grid ; update output.
173    o Added functionality to grdchk:
174      pick global i,j,k position (or nearest wet) where to perform check.
175    
176    checkpoint52l_post
177    o new land formulation:
178      a) use ground enthalpy as prognostic variable to ensure exact
179         energy conservation.
180      b) account for water temperature and for latent heat of freezing
181         in all processes (rain, run-off, ground storage)
182      c) compute surface and ground temperature implicitly.
183    o aim_v23 modification for new land model:
184      a) Treat separately land / ocean / sea-ice surface fluxes
185         to allow implicit computation of land & sea-ice surface temp.
186      b) add snow precipitation.
187    checkpoint52l_pre
188    
189    o fix problem (when 1 tile is empty) in min/max monitor.
190    o fix bug in timeAve (u,vZetatave in common block)
191    o no restoring terms under ice for pkg/seaice
192    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
193    o bug fix for pkg/seaice pickups
194    o change MNC call locations and add coordinate attributes
195    o mask vorticity at the corner ; affects global_ocean.cs output
196    o fix ini_curvilinear_grid ; test CS experiments with mpi
197    o aim.5l_cs: modify sea-ice fraction input file ; update output
198    o exf: Adding simple range check routine for exf fields after read
199    
200    checkpoint52k_post
201    o removed top-level directory "diags"
202      - we migrated these functions to pkg/timeave a long time ago
203    o fixed bug introduced in pkg/monitor
204    o accuracy ctrlprec = 32 insuffient for gradient checks using
205      averaged fields (I/O via cost_averages)
206      -> use ctrl.h in active_file*.F to control I/O precision.
207    o paramter list of CALL ADTHE_MAIN_LOOP
208    o added initial do_the_model_io to ecco
209    o set all ...Freq to zero after cost_final
210      taveFreq, dumpFreq, pChkptFreq
211    o MAIN and ECCO differentiability restored
212    
213    checkpoint52j_post
214    o fix nchklev in tamc.h for global_ocean...
215    o Bringing flow and store directives up-to-date
216    o Really weird thing!
217      call do_the_model_io from the_main_loop with parameters
218      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
219      TAF places a faulty re-call of initialise_varia
220      after cost_final call which should not be there!
221    checkpoint52j_pre
222    
223    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
224      error messages
225    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
226    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
227      debug output
228    o modfied mdsio_writefield.F to handle non-global files under exch2
229    o update AIM Cubed-Sphere exp (aim.5l_cs):
230      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
231    o update AIM Equatorial Channel exp:
232      use standard aim_v23 pkg and change the SST fields to be more realistic.
233    o globalFile now works with exch2
234    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
235      mon_vort3.F to make exch2 friendly with >1 tile per cube face
236    o limit timeave output for hi-res integrations
237    
238    checkpoint52i_post
239    o removed CPP_EEOPTIONS.h from verification/*/code
240    o updated the tiling for global_ocean_pressure
241    checkpoint52i_pre
242    
243    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
244      the old pkg/aim).
245    
246    checkpoint52h_pre
247    o shortened offending lines in exch2_send_rx?.template
248    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
249    o genmake2: add build & execute test for NetCDF code
250    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
251      old grid files, moved CPP_EEMACROS.h to pkg/exch2
252    o added useSingleCPUIO flag to monitor.F and mon_out.F
253    o added temporary hack for sea-ice dynamics on the cube:
254      metric terms are ignored and it is assumed that
255      there is no sea-ice on cube faces 1, 2, 4, and 5.
256    
257    checkpoint52f_post
258    o added exch2 cube routines to pkg/exch2
259    o modified hs94.cs-32x32x5 to use it
260    o added new grid files to hs94.cs-32x32x5
261    checkpoint52f_pre
262    
263    checkpoint52e_post
264    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
265      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
266    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
267      to work with implicit vertical advection and AB ;
268    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
269    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
270     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
271    checkpoint52e_pre
272    
273    o fix bug in impldiff when Nr=1 or Nr=2.
274    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
275    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
276    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
277      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
278    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
279    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
280    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
281    
282    checkpoint52d_post
283    o re-tiled many expts to allow comparison in multi-processor mode
284      - updated output accordingly
285      - changed hs94.128x64x5 to use intial T from file rather than use the
286        random number generator
287    o add infrastructure in model routines for fizhi and gridalt packages
288    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
289    o changes to permit hi-res, cubed-sphere, configuration
290      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
291      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
292      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
293        of surface winds for the cube
294      (A verification experiment, based on global_ocean.cs32x15, but with
295       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
296       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
297       complete with example surface forcing files and matlab scripts to look
298       at the output and compare it with that of global_ocean.cs32x15.)
299    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
300       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
301       to conform to the common rule.
302    o check-in the first version of the coupler + interfaces for multi-components
303       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
304       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
305       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
306       - ocean and atmos. share the same horizontal grid (no interpolation).
307       - exchanges between component and coupler is done in forward_step
308    o new verification experiment, cpl_aim+ocn:
309       coupled ocean - AIM atmosphere on cs32 grid.
310    
311    checkpoint52d_pre
312    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
313    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
314    
315    checkpoint52c_post
316    o Fixing OPTIONS files for use of exf:
317      - ALLOW_ECCO not needed
318      - ECCO_CPPOPTIONS.h should not be included from
319        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
320        as has been the case in the past
321      - All cal/exf related options are currently set in
322        single header file. Should remain so until we
323        agree on a consistent new policy.
324    o Removed all CPP options for cal package.
325      cal has no more CPP options.
326    o modified STOREs in GAD_ADVECTION
327    o corrected key comp. for passkey
328    
329    checkpoint52b_post
330    o new version: "thsice" of thermodynamic sea-ice pkg:
331     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
332     - modify fluxes but do not change theta directly;
333     - light cleaning of bulk_force pkg (still needed with thsice).
334     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
335       + output_thsice.txt to test thsice & bulk_force pkgs.
336    o put back grid & coriolis monitor output.
337    checkpoint52b_pre
338    
339    o call "do_the_model_io" at the beginning (=> dump initial state)
340    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
341    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
342      (need info on NUMBER_OF_PTRACERS)
343    o missing PTRACERS headers in some routines
344    o default tamc.h in pkg/autodiff supposed to crash
345      to ensure proper customization
346    
347    checkpoint52a_post
348    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
349      - moved surfaceTendencyTice from pkg/seaice to main code
350      - subroutine FREEZE_SURFACE now limits only surface temperature
351        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
352        => new output.txt for global_ocean.cs32x15 & global_with_exf
353      - keep the old version of FREEZE for backward compatibility;
354        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
355      - corresponding modifs for TAF directives
356    o added surface flux output variables to TIMEAVE_STATVARS
357    o time-averaged output for pkg/ptracers
358    o fix problem with ECCO-related divided adjoint
359      snapshot file was missing some ad-variables,
360      but no warning issued by TAF
361    
362    checkpoint52a_pre
363    o some bug fixes for #undef REAL4_IS_SLOW
364    
365    checkpoint52 = ecco_c52_e35
366    o after testing adjoints of checkpoint51u_post
367    
368    checkpoint51u_post
369    o this is the post-merge tag of the ecco-branch
370      (needs another clean checkout and re-testing)
371    o various natl_box_adjoint configs and results
372      but no input fields
373    o obcs adjoint not yet merged!
374    o adding ECCO global 1x1 and 2x2 degree configs
375    o updated/extended some store directives for seaice
376    o pkg/ecco now containes ecco-specific part of cost function
377    o top level routines the_main_loop, forward_step
378      supersede those in model/src/
379      previous input data.cost now in data.ecco
380      (new namelist ecco_cost_nml)
381    o in ctrl/ cleaned some cross-dependencies and updated CPP options
382    
383    checkpoint51t_post
384    o this is the pre-merge tag of the ecco-branch
385    
386    checkpoint51s_post
387    o cleanup: removed various obsolete #define-s
388    o pkg/grdchk
389      - renamed 'ph-grd 3' to 'grad-res'
390      - merged from ecco-branch
391        (remaining bug fixes for obcs gradient checks)
392      - additional high-precision output for testreport
393        (grep for 'precision_grdchk_result')
394    
395    checkpoint51r_post
396    o cleaned up or removed CPP_OPTIONS.h files
397    o updated results for some of the tests to reflect the new
398      optfiles (-ieee: -O0 instead of -O3)
399    
400    checkpoint51q_post
401    o cd_code:
402      - moved cd_scheme.F -> cd_code_scheme.F
403      - separate read_checkpoint from cd_code_ini_vars.F
404      - separated cd_code part from write_checkpoint

408    o ctrl package totally restructured
409      - pack/unpack now optional and decoupled from
410        xx_/adxx_ I/O
411      - ctrl_pack/unpack cleaned
412        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
413      - confined inclusion of AD_CONFIG.h to where necessary.
414    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
415    
416    checkpoint51p_post
417    o create initial cd_code package
418      - WARNING: the initialization of fields within packages
419        is broken because INI_FIELDS (where READ_CHECKPOINT is
420        called) is called *before* PACKAGES_INIT_VARIABLES.
421        This seems to be backwards since
422        1) its important to initially zero the entire field including
423           the "halo" region
424        2) zeroing needs to be done *before* reading pickup info
425           and the pickup call might or might not happen in any
426           particular run
427      - this needs an overhaul for R2
428    o cleanup verification/*/code/GMREDI_OPTIONS.h
