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