3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o replaced all occurrences of 1/CSTICE or 1/CSUICE
7      - they caused a segmentation fault under certain circumstances
8      - removed unused field WATR
9    o bug fix in exf-package:
10      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
11         now reflect that.
12    o small fixes in the cal-package:
13      - set reference date to first of January for the 'model'-calendar
14      - failing of cal_CheckDate in cal_FullDate now actually results in a
15        warning
16    o small modifications in exf-package to increase flexibility:
17      - change climtempfreeze from a constant to a runtime parameter that
18        is specified in data.exf_clim (default = -1.9)
19      - introduce runtime parameter windstressmax (default = 2.0) that is
20        specified in data.exf
21    o fix in pkg/thsice:
22      - update Evap (Tsf changes) to be consistent with Latent heat flux
23      - maintain snow precipitation unchanged (even if Tsf >=0).
24     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
25    
26    checkpoint52m_post
27    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
28      this does not change any of the results, because myIter=0 in swfrac always
29      lead to jwtype=2 (the default anyway), but the call makes little sense
30      as a default
31    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
32    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
33      atmospheric model (AIM) to use it ; add a "slab ocean" component.
34    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
35    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
36    o extending useSingleCpuIO option to work with new exch2 I/O format
37      - old-style, missing-tile I/O is still accessible by defining CPP
38        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
39    o monitor package can write to NetCDF files and/or STDOUT
40    o fix re-definition bug in MNC_GRID_INIT_ALL()
41    o doc/api_reference added
42      - a framework for building an API Reference Manual using all
43        the "protex" comments embedded in the code
44      - see pkg/generic_advdiff, pkg/mnc for examples
45    o MNC:
46      - make myThid the last argument for all subroutines
47      - new default for the grid files: NO halos
48      - add useMNC and other run-time flags
49      - separate per-file-group handling of the unlimited dimension
50      - early initialization of MNC w/ flags read at the eeboot stage
51        and lookup tables set in initialize_fixed
52      - write all MNC output to a freshly-created directory
53    o thermodynamics sea-ice (thsice) is now tested with testreport.
54    o test exp. advect_cs: use the standard cs32 grid ; update output.
55    o Added functionality to grdchk:
56      pick global i,j,k position (or nearest wet) where to perform check.
57    
58    checkpoint52l_post
59    o new land formulation:
60      a) use ground enthalpy as prognostic variable to ensure exact
61         energy conservation.
62      b) account for water temperature and for latent heat of freezing
63         in all processes (rain, run-off, ground storage)
64      c) compute surface and ground temperature implicitly.
65    o aim_v23 modification for new land model:
66      a) Treat separately land / ocean / sea-ice surface fluxes
67         to allow implicit computation of land & sea-ice surface temp.
68      b) add snow precipitation.
69    checkpoint52l_pre
70    
71    o fix problem (when 1 tile is empty) in min/max monitor.
72    o fix bug in timeAve (u,vZetatave in common block)
73    o no restoring terms under ice for pkg/seaice
74    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
75    o bug fix for pkg/seaice pickups
76    o change MNC call locations and add coordinate attributes
77    o mask vorticity at the corner ; affects global_ocean.cs output
78    o fix ini_curvilinear_grid ; test CS experiments with mpi
79    o aim.5l_cs: modify sea-ice fraction input file ; update output
80    o exf: Adding simple range check routine for exf fields after read
81    
82    checkpoint52k_post
83    o removed top-level directory "diags"
84      - we migrated these functions to pkg/timeave a long time ago
85    o fixed bug introduced in pkg/monitor
86    o accuracy ctrlprec = 32 insuffient for gradient checks using
87      averaged fields (I/O via cost_averages)
88      -> use ctrl.h in active_file*.F to control I/O precision.
89    o paramter list of CALL ADTHE_MAIN_LOOP
90    o added initial do_the_model_io to ecco
91    o set all ...Freq to zero after cost_final
92      taveFreq, dumpFreq, pChkptFreq
93    o MAIN and ECCO differentiability restored
94    
95    checkpoint52j_post
96    o fix nchklev in tamc.h for global_ocean...
97    o Bringing flow and store directives up-to-date
98    o Really weird thing!
99      call do_the_model_io from the_main_loop with parameters
100      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
101      TAF places a faulty re-call of initialise_varia
102      after cost_final call which should not be there!
103    checkpoint52j_pre
104    
105    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
106      error messages
107    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
108    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
109      debug output
110    o modfied mdsio_writefield.F to handle non-global files under exch2
111    o update AIM Cubed-Sphere exp (aim.5l_cs):
112      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
113    o update AIM Equatorial Channel exp:
114      use standard aim_v23 pkg and change the SST fields to be more realistic.
115    o globalFile now works with exch2
116    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
117      mon_vort3.F to make exch2 friendly with >1 tile per cube face
118    o limit timeave output for hi-res integrations
119    
120    checkpoint52i_post
121    o removed CPP_EEOPTIONS.h from verification/*/code
122    o updated the tiling for global_ocean_pressure
123    checkpoint52i_pre
124    
125    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
126      the old pkg/aim).
127    
128    checkpoint52h_pre
129    o shortened offending lines in exch2_send_rx?.template
130    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
131    o genmake2: add build & execute test for NetCDF code
132    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
133      old grid files, moved CPP_EEMACROS.h to pkg/exch2
134    o added useSingleCPUIO flag to monitor.F and mon_out.F
135    o added temporary hack for sea-ice dynamics on the cube:
136      metric terms are ignored and it is assumed that
137      there is no sea-ice on cube faces 1, 2, 4, and 5.
138    
139    checkpoint52f_post
140    o added exch2 cube routines to pkg/exch2
141    o modified hs94.cs-32x32x5 to use it
142    o added new grid files to hs94.cs-32x32x5
143    checkpoint52f_pre
144    
145    checkpoint52e_post
146    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
147      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
148    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
149      to work with implicit vertical advection and AB ;
150    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
151    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
152     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
153    checkpoint52e_pre
154    
155    o fix bug in impldiff when Nr=1 or Nr=2.
156    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
157    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
158    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
159      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
160    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
161    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
162    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
163    
164    checkpoint52d_post
165    o re-tiled many expts to allow comparison in multi-processor mode
166      - updated output accordingly
167      - changed hs94.128x64x5 to use intial T from file rather than use the
168        random number generator
169    o add infrastructure in model routines for fizhi and gridalt packages
170    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
171    o changes to permit hi-res, cubed-sphere, configuration
172      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
173      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
174      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
175        of surface winds for the cube
176      (A verification experiment, based on global_ocean.cs32x15, but with
177       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
178       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
179       complete with example surface forcing files and matlab scripts to look
180       at the output and compare it with that of global_ocean.cs32x15.)
181    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
182       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
183       to conform to the common rule.
184    o check-in the first version of the coupler + interfaces for multi-components
185       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
186       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
187       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
188       - ocean and atmos. share the same horizontal grid (no interpolation).
189       - exchanges between component and coupler is done in forward_step
190    o new verification experiment, cpl_aim+ocn:
191       coupled ocean - AIM atmosphere on cs32 grid.
192    
193    checkpoint52d_pre
194    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
195    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
196    
197    checkpoint52c_post
198    o Fixing OPTIONS files for use of exf:
199      - ALLOW_ECCO not needed
200      - ECCO_CPPOPTIONS.h should not be included from
201        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
202        as has been the case in the past
203      - All cal/exf related options are currently set in
204        single header file. Should remain so until we
205        agree on a consistent new policy.
206    o Removed all CPP options for cal package.
207      cal has no more CPP options.
208    o modified STOREs in GAD_ADVECTION
209    o corrected key comp. for passkey
210    
211    checkpoint52b_post
212    o new version: "thsice" of thermodynamic sea-ice pkg:
213     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
214     - modify fluxes but do not change theta directly;
215     - light cleaning of bulk_force pkg (still needed with thsice).
216     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
217       + output_thsice.txt to test thsice & bulk_force pkgs.
218    o put back grid & coriolis monitor output.
219    checkpoint52b_pre
220    
221    o call "do_the_model_io" at the beginning (=> dump initial state)
222    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
223    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
224      (need info on NUMBER_OF_PTRACERS)
225    o missing PTRACERS headers in some routines
226    o default tamc.h in pkg/autodiff supposed to crash
227      to ensure proper customization
228    
229    checkpoint52a_post
230    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
231      - moved surfaceTendencyTice from pkg/seaice to main code
232      - subroutine FREEZE_SURFACE now limits only surface temperature
233        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
234        => new output.txt for global_ocean.cs32x15 & global_with_exf
235      - keep the old version of FREEZE for backward compatibility;
236        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
237      - corresponding modifs for TAF directives
238    o added surface flux output variables to TIMEAVE_STATVARS
239    o time-averaged output for pkg/ptracers
240    o fix problem with ECCO-related divided adjoint
241      snapshot file was missing some ad-variables,
242      but no warning issued by TAF
243    
244    checkpoint52a_pre
245    o some bug fixes for #undef REAL4_IS_SLOW
246    
247    checkpoint52 = ecco_c52_e35
248    o after testing adjoints of checkpoint51u_post
249    
250    checkpoint51u_post
251    o this is the post-merge tag of the ecco-branch
252      (needs another clean checkout and re-testing)
253    o various natl_box_adjoint configs and results
254      but no input fields
255    o obcs adjoint not yet merged!
256    o adding ECCO global 1x1 and 2x2 degree configs
257    o updated/extended some store directives for seaice
258    o pkg/ecco now containes ecco-specific part of cost function
259    o top level routines the_main_loop, forward_step
260      supersede those in model/src/
261      previous input data.cost now in data.ecco
262      (new namelist ecco_cost_nml)
263    o in ctrl/ cleaned some cross-dependencies and updated CPP options
264    
265    checkpoint51t_post
266    o this is the pre-merge tag of the ecco-branch
267    
268    checkpoint51s_post
269    o cleanup: removed various obsolete #define-s
270    o pkg/grdchk
271      - renamed 'ph-grd 3' to 'grad-res'
272      - merged from ecco-branch
273        (remaining bug fixes for obcs gradient checks)
274      - additional high-precision output for testreport
275        (grep for 'precision_grdchk_result')
276    
277    checkpoint51r_post
278    o cleaned up or removed CPP_OPTIONS.h files
279    o updated results for some of the tests to reflect the new
280      optfiles (-ieee: -O0 instead of -O3)
281    
282    checkpoint51q_post
283    o cd_code:
284      - moved cd_scheme.F -> cd_code_scheme.F
285      - separate read_checkpoint from cd_code_ini_vars.F
286      - separated cd_code part from write_checkpoint
287      - updated AD_SOURCE, generated .flow
288      - added CD_CODE_VARS.h to the_main_loop
289      - Moving cd_code specific store dir.s to pkg/cd_code
290    o ctrl package totally restructured
291      - pack/unpack now optional and decoupled from
292        xx_/adxx_ I/O
293      - ctrl_pack/unpack cleaned
294        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
295      - confined inclusion of AD_CONFIG.h to where necessary.
296    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
297    
298    checkpoint51p_post
299    o create initial cd_code package
300      - WARNING: the initialization of fields within packages
301        is broken because INI_FIELDS (where READ_CHECKPOINT is
302        called) is called *before* PACKAGES_INIT_VARIABLES.
303        This seems to be backwards since
304        1) its important to initially zero the entire field including
305           the "halo" region
306        2) zeroing needs to be done *before* reading pickup info
307           and the pickup call might or might not happen in any
308           particular run
309      - this needs an overhaul for R2
310    o cleanup verification/*/code/GMREDI_OPTIONS.h
311    o cleanup testreport
312    
313    checkpoint51o_post
314    o bringing AD-related verif's up to date with genmake2
315      - carbon/
316      - global_ocean.90x40x15/
317      - hs.94.1x64x5/
318      - (front_relax/ )
319    o (more) consistent directory structure for AD-related verif.'s
320    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
321    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
322    o bug fix in find_alpha.F for MDJWF:
323      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
324        change rho -> rho-rhoConst
325      - replace call find_rho to find_rhonum
326    o initialisation of rFlx extended to full array (required by TAF)
327      and shifted to thermodynamics
328    o removed PTRACERS.h in ptracers routine
329    o added surfacetendencyPtr to S/R parameter list pracers_forcing
330    o Correcting initialisations for fVerU, fVerV.
331    o helping TAF to recognize dependency on kUp for
332      fVerU, fVerV
333    o Replacing delZ by delR in pkg/ctrl/
334    checkpoint51o_pre
335    
336    o undid all of cp51 pending some cleanups and discussion
337    o added the [#include "AD_CONFIG.h"] statement to all files that need
338       it for adjoint/tl #defines
339     o re-worked the build logic in genmake2 to support AD_CONFIG.h
340     o removed tools/genmake since it no longer works
341    
342    checkpoint51n_post
343    o modifications to make FREEZE flux visible to pkg/kpp
344      - moved surfaceTendencyTice from pkg/seaice to main code
345      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
346      - subroutine FREEZE now limits only surface temperature
347        (this means new output.txt for global_ocean.90x40x15,
348         global_ocean.cs32x15, and global_with_exf)
349    o added surface flux output variables to TIMEAVE_STATVARS
350    
351    checkpoint51n_pre
352    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
353    o added [#include "AD_CONFIG.h"] to all files that use the following
354      defines:
355      - ALLOW_ADJOINT_RUN
356      - ALLOW_TANGENTLINEAR_RUN
357      - ALLOW_ECCO_OPTIMIZATION
358    
359    checkpoint51m_post
360    o incorporating changes to get TAMC/TAF working in genmake2
361      - added new TAMC/TAF targets to the Makefile
362      - various cleanups related to package handling
363      - these changes should have no impact on the forward model
364    
365    checkpoint51l_post
366    o changes to pkg/cal and pkg/exf that allow and speed-up long integrations
367     - faster algorithm for cal_addtime.F

369     - pkg/exf *startdate variables changed from calendar date to
370       model integration time
371    
372    checkpoint51l_pre
373    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
374    o enable to apply restoring on S & T only in a latitude band.
375    o update output (external_forcing_surf modif. change truncation errors)
376       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
377    
378    checkpoint51k_post
379    o change default to: useNHMTerms=.FALSE.
380     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
381       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5
382     - new output.txt for idealized oceanic exp (NHMTerms are now turned off):

398    o Moving pkg-specific flow directives to corresponding pkg
399      Moving pkg-specific differentiation list to corresponding pkg
400      Moving pkg-specific checkpoint-lev storing to corresponding pkg
401      ---> conventions are
402           - pkg_ad.flow
403           - pkg_ad_diff.list
404           - pkg_ad_check_lev?_dir.h
