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

407    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
408    
409    checkpoint51p_post
410    o create initial cd_code package
411      - WARNING: the initialization of fields within packages
412        is broken because INI_FIELDS (where READ_CHECKPOINT is
413        called) is called *before* PACKAGES_INIT_VARIABLES.
414        This seems to be backwards since
415        1) its important to initially zero the entire field including
416           the "halo" region
417        2) zeroing needs to be done *before* reading pickup info
418           and the pickup call might or might not happen in any
419           particular run
420      - this needs an overhaul for R2
421    o cleanup verification/*/code/GMREDI_OPTIONS.h
422    o cleanup testreport
