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