3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o monitor package can write to NetCDF files and/or STDOUT
7    o fix re-definition bug in MNC_GRID_INIT_ALL()
8    o doc/api_reference added
9      - a framework for building an API Reference Manual using all
10        the "protex" comments embedded in the code
11      - see pkg/generic_advdiff, pkg/mnc for examples
12    o MNC:
13      - make myThid the last argument for all subroutines
14      - new default for the grid files: NO halos
15      - add useMNC and other run-time flags
16      - separate per-file-group handling of the unlimited dimension
17      - early initialization of MNC w/ flags read at the eeboot stage
18        and lookup tables set in initialize_fixed
19      - write all MNC output to a freshly-created directory
20    o thermodynamics sea-ice (thsice) is now tested with testreport.
21    o test exp. advect_cs: use the standard cs32 grid ; update output.
22    o Added functionality to grdchk:
23      pick global i,j,k position (or nearest wet) where to perform check.
24    
25    checkpoint52l_post
26    o new land formulation:
27      a) use ground enthalpy as prognostic variable to ensure exact
28         energy conservation.
29      b) account for water temperature and for latent heat of freezing
30         in all processes (rain, run-off, ground storage)
31      c) compute surface and ground temperature implicitly.
32    o aim_v23 modification for new land model:
33      a) Treat separately land / ocean / sea-ice surface fluxes
34         to allow implicit computation of land & sea-ice surface temp.
35      b) add snow precipitation.
36    checkpoint52l_pre
37    
38    o fix problem (when 1 tile is empty) in min/max monitor.
39    o fix bug in timeAve (u,vZetatave in common block)
40    o no restoring terms under ice for pkg/seaice
41    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
42    o bug fix for pkg/seaice pickups
43    o change MNC call locations and add coordinate attributes
44    o mask vorticity at the corner ; affects global_ocean.cs output
45    o fix ini_curvilinear_grid ; test CS experiments with mpi
46    o aim.5l_cs: modify sea-ice fraction input file ; update output
47    o exf: Adding simple range check routine for exf fields after read
48    
49    checkpoint52k_post
50    o removed top-level directory "diags"
51      - we migrated these functions to pkg/timeave a long time ago
52    o fixed bug introduced in pkg/monitor
53    o accuracy ctrlprec = 32 insuffient for gradient checks using
54      averaged fields (I/O via cost_averages)
55      -> use ctrl.h in active_file*.F to control I/O precision.
56    o paramter list of CALL ADTHE_MAIN_LOOP
57    o added initial do_the_model_io to ecco
58    o set all ...Freq to zero after cost_final
59      taveFreq, dumpFreq, pChkptFreq
60    o MAIN and ECCO differentiability restored
61    
62    checkpoint52j_post
63    o fix nchklev in tamc.h for global_ocean...
64    o Bringing flow and store directives up-to-date
65    o Really weird thing!
66      call do_the_model_io from the_main_loop with parameters
67      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
68      TAF places a faulty re-call of initialise_varia
69      after cost_final call which should not be there!
70    checkpoint52j_pre
71    
72    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
73      error messages
74    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
75    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
76      debug output

78    o update AIM Cubed-Sphere exp (aim.5l_cs):
79      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
80    o update AIM Equatorial Channel exp:
81      use standard aim_v23 pkg and change the SST fields to be more realistic.
82    o globalFile now works with exch2
83    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
84      mon_vort3.F to make exch2 friendly with >1 tile per cube face
85    o limit timeave output for hi-res integrations
86    
87    checkpoint52i_post

89    o updated the tiling for global_ocean_pressure
90    checkpoint52i_pre
91    
92    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of

94    
95    checkpoint52h_pre
96    o shortened offending lines in exch2_send_rx?.template
97    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
98    o genmake2: add build & execute test for NetCDF code
99    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
100      old grid files, moved CPP_EEMACROS.h to pkg/exch2
101    o added useSingleCPUIO flag to monitor.F and mon_out.F
102    o added temporary hack for sea-ice dynamics on the cube:
103      metric terms are ignored and it is assumed that
104      there is no sea-ice on cube faces 1, 2, 4, and 5.
105    
106    checkpoint52f_post
107    o added exch2 cube routines to pkg/exch2
108    o modified hs94.cs-32x32x5 to use it

110    checkpoint52f_pre
111    
112    checkpoint52e_post
113    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
114      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
115    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
116      to work with implicit vertical advection and AB ;
117    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
118    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
119     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
120    checkpoint52e_pre
121    
122    o fix bug in impldiff when Nr=1 or Nr=2.
123    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
124    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
125    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
126      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure

130    
131    checkpoint52d_post
132    o re-tiled many expts to allow comparison in multi-processor mode
133      - updated output accordingly
134      - changed hs94.128x64x5 to use intial T from file rather than use the
135        random number generator
136    o add infrastructure in model routines for fizhi and gridalt packages
137    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
138    o changes to permit hi-res, cubed-sphere, configuration
139      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
140      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
141      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
142        of surface winds for the cube
143      (A verification experiment, based on global_ocean.cs32x15, but with
144       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
145       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
146       complete with example surface forcing files and matlab scripts to look
147       at the output and compare it with that of global_ocean.cs32x15.)
148    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
149       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
150       to conform to the common rule.
151    o check-in the first version of the coupler + interfaces for multi-components
152       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
153       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
154       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
155       - ocean and atmos. share the same horizontal grid (no interpolation).
156       - exchanges between component and coupler is done in forward_step
157    o new verification experiment, cpl_aim+ocn:
158       coupled ocean - AIM atmosphere on cs32 grid.
159    
160    checkpoint52d_pre
161    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
162    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
163    
164    checkpoint52c_post
165    o Fixing OPTIONS files for use of exf:
166      - ALLOW_ECCO not needed
167      - ECCO_CPPOPTIONS.h should not be included from
168        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
169        as has been the case in the past
170      - All cal/exf related options are currently set in
171        single header file. Should remain so until we
172        agree on a consistent new policy.
173    o Removed all CPP options for cal package.
174      cal has no more CPP options.
175    o modified STOREs in GAD_ADVECTION
176    o corrected key comp. for passkey
177    
178    checkpoint52b_post
179    o new version: "thsice" of thermodynamic sea-ice pkg:
180     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
181     - modify fluxes but do not change theta directly;
182     - light cleaning of bulk_force pkg (still needed with thsice).
183     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
184       + output_thsice.txt to test thsice & bulk_force pkgs.
185    o put back grid & coriolis monitor output.
186    checkpoint52b_pre
187    
188    o call "do_the_model_io" at the beginning (=> dump initial state)
189    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
190    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
191      (need info on NUMBER_OF_PTRACERS)
192    o missing PTRACERS headers in some routines
193    o default tamc.h in pkg/autodiff supposed to crash
194      to ensure proper customization
195    
196    checkpoint52a_post
197    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
198      - moved surfaceTendencyTice from pkg/seaice to main code
199      - subroutine FREEZE_SURFACE now limits only surface temperature
200        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
201        => new output.txt for global_ocean.cs32x15 & global_with_exf
202      - keep the old version of FREEZE for backward compatibility;
203        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
204      - corresponding modifs for TAF directives
205    o added surface flux output variables to TIMEAVE_STATVARS
206    o time-averaged output for pkg/ptracers
207    o fix problem with ECCO-related divided adjoint

209      but no warning issued by TAF
210    
211    checkpoint52a_pre
212    o some bug fixes for #undef REAL4_IS_SLOW
213    
214    checkpoint52 = ecco_c52_e35
215    o after testing adjoints of checkpoint51u_post
216    
217    checkpoint51u_post
218    o this is the post-merge tag of the ecco-branch
219      (needs another clean checkout and re-testing)
220    o various natl_box_adjoint configs and results
221      but no input fields
222    o obcs adjoint not yet merged!
223    o adding ECCO global 1x1 and 2x2 degree configs
224    o updated/extended some store directives for seaice
225    o pkg/ecco now containes ecco-specific part of cost function
226    o top level routines the_main_loop, forward_step
227      supersede those in model/src/
228      previous input data.cost now in data.ecco
229      (new namelist ecco_cost_nml)
230    o in ctrl/ cleaned some cross-dependencies and updated CPP options
231    
232    checkpoint51t_post
233    o this is the pre-merge tag of the ecco-branch
234    
235    checkpoint51s_post

237    o pkg/grdchk
238      - renamed 'ph-grd 3' to 'grad-res'
239      - merged from ecco-branch
240        (remaining bug fixes for obcs gradient checks)
241      - additional high-precision output for testreport
242        (grep for 'precision_grdchk_result')
243    
244    checkpoint51r_post
245    o cleaned up or removed CPP_OPTIONS.h files
246    o updated results for some of the tests to reflect the new
247      optfiles (-ieee: -O0 instead of -O3)
248    
249    checkpoint51q_post
250    o cd_code:
251      - moved cd_scheme.F -> cd_code_scheme.F
252      - separate read_checkpoint from cd_code_ini_vars.F
253      - separated cd_code part from write_checkpoint
254      - updated AD_SOURCE, generated .flow
255      - added CD_CODE_VARS.h to the_main_loop
256      - Moving cd_code specific store dir.s to pkg/cd_code
257    o ctrl package totally restructured
258      - pack/unpack now optional and decoupled from
259        xx_/adxx_ I/O
260      - ctrl_pack/unpack cleaned
261        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
262      - confined inclusion of AD_CONFIG.h to where necessary.
263    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
264    
265    checkpoint51p_post
266    o create initial cd_code package
267      - WARNING: the initialization of fields within packages
268        is broken because INI_FIELDS (where READ_CHECKPOINT is
269        called) is called *before* PACKAGES_INIT_VARIABLES.
270        This seems to be backwards since
271        1) its important to initially zero the entire field including
272           the "halo" region
273        2) zeroing needs to be done *before* reading pickup info
274           and the pickup call might or might not happen in any
275           particular run
276      - this needs an overhaul for R2
277    o cleanup verification/*/code/GMREDI_OPTIONS.h
278    o cleanup testreport
279    
280    checkpoint51o_post
281    o bringing AD-related verif's up to date with genmake2

283      - global_ocean.90x40x15/
284      - hs.94.1x64x5/
285      - (front_relax/ )
286    o (more) consistent directory structure for AD-related verif.'s
287    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
288    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
289    o bug fix in find_alpha.F for MDJWF:
290      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
291        change rho -> rho-rhoConst
292      - replace call find_rho to find_rhonum
293    o initialisation of rFlx extended to full array (required by TAF)
294      and shifted to thermodynamics
295    o removed PTRACERS.h in ptracers routine
296    o added surfacetendencyPtr to S/R parameter list pracers_forcing
297    o Correcting initialisations for fVerU, fVerV.
298    o helping TAF to recognize dependency on kUp for

304    o added the [#include "AD_CONFIG.h"] statement to all files that need
305       it for adjoint/tl #defines
306     o re-worked the build logic in genmake2 to support AD_CONFIG.h
307     o removed tools/genmake since it no longer works
308

310    o modifications to make FREEZE flux visible to pkg/kpp
311      - moved surfaceTendencyTice from pkg/seaice to main code
312      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
313      - subroutine FREEZE now limits only surface temperature
314        (this means new output.txt for global_ocean.90x40x15,
315         global_ocean.cs32x15, and global_with_exf)
316    o added surface flux output variables to TIMEAVE_STATVARS
317    
318    checkpoint51n_pre
319    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
320    o added [#include "AD_CONFIG.h"] to all files that use the following
321      defines:
322      - ALLOW_ADJOINT_RUN
323      - ALLOW_TANGENTLINEAR_RUN

339    checkpoint51l_pre
340    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
341    o enable to apply restoring on S & T only in a latitude band.
342    o update output (external_forcing_surf modif. change truncation errors)
343       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
344    
345    checkpoint51k_post
346    o change default to: useNHMTerms=.FALSE.
347     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
348       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5

371           - pkg_ad_check_lev?_dir.h
372    
373    checkpoint51i_post
374    o merge of the branch-genmake2
375      - knowingly breaks the older genmake
