4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
8    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
9    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
10      not mnc -- this mistake was found by JMC and is now corrected
11    
12    checkpoint57g_post
13    o add Adams-Bashforth 3rd Order time stepping:
14      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
15      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
16    checkpoint57g_pre
17    
18    o make lambda[Theta,Salt]ClimRelax spatially varying
19      (default remains spatially uniform constant based on tau)
20    o added new control variables
21      * init. uVel, vVel, etanN
22      * lambda[Theta,Salt]ClimRelax
23    o separate masks used for ctrl_pack/unpack 'from write_grid' output
24      (suggested by G. Forget)
25    
26    checkpoint57f_post
27    o add parameter "baseTime" = model base time = time at iteration zero
28      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
29      account for baseTime shift
30    o move Coriolis arrays from PARAMS.h to GRID.h
31    checkpoint57f_pre
32    
33    o mnc-ifying the seaice package
34    o introduced an alternative length scale calculation for use in the limiting
35      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
36    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
37    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
38      as well as grad(vort3).  Made it compatible with both approximate form
39      for the cubed sphere and full form of these gradients.  Added flag
40      useFullLeith to select between approximate and full form.  
41    o add "d0" in getcon.F to reduce differences between compilers/platforms
42      update output.txt of exp. fizhi-gridalt-hs
43    o change port_rand funtion to allow to set the seed.
44    o fix obscure MNC bug involving conversion between reals and integers
45      - it caused no problems with certain (eg. gcc, ifc) compilers but the
46        new version is now more standards-compliant
47    o adjoint-related modifications
48      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
49      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
50      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
51    
52    checkpoint57e_post
53    o Adding eddy stress controls a la Ferreira et al.
54    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
55    
56    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
57      update output.txt of exp. fizhi-gridalt-hs
58    o add more "Z" dimensions and associated coordinate vars to MNC
59    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
60    o parameter calendarDumps: when set, approximate months (30-31 days) and years
61      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
62      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
63      months and years.  Requires pkg/cal.
64    o diagnostics: add pickup functionality
65      - off by default for backwards compatibility
66      - current version only uses MDSIO -- MNC will be added
67    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
68    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
69    
70    checkpoint57d_post
71    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
72    o modify verification/ideal_2D_oce so that it tests the creation of mnc
73      output from the diagnostics package
74    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
75    o make genmake2 more portable by using ".$FS" instead of ".f" for more
76      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
77    o add coordinate variables to the MNC output from the diagnostics package
78    o change MNC-flags default value: true when useMNC=TRUE
79    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
80      the ability (off by default) to read the grid information using MNC
81    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
82    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
83    o do snap-shot diagnostics at the middle of the time-interval (instead of
84      at the end).
85    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
86      new test for AIM with thSIce + slab-ocean
87    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
88    o move state variable diagnostics to the beginning of the time step ;
89      (note: still needs some work specially for snap-shot diagnostics)
90      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
91    
92    checkpoint57c_post
93    o Change testing option (-ieee) to get closer agreement between g77 & ifort
94    o generate new output.txt files on faulks with g77 & the new -ieee option
95    checkpoint57c_pre
96    
97    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
98      update output.txt of exp. global_ocean.90x40x15
99    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
100      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
101    o add saltFlux(+File) forcing capability with periodicExternalForcing
102    o allow to use pkg diagnostics for GM-Redi & ThSIce output
103    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
104    o improvements for the MNC output from DIAGNOSTICS:
105      - correct handling of the unlimitied dimension
106      - all dims now have associated coordinate variables
107      - variables located at U, V, and Corner ("Z") points are now written
108        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
109        *all* data points are output
110    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
111    o added pkg/seaice/seaice_monitor.F
112    o mdsio_readfield.F can now read files visible only to master MPI process.
113    o pkg/seaice: some test code for ice-modified ocean stress
114    o exf_getffields interpolation defaults to bilinear for all scalar forcing
115      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
116      spurious negative numbers for precipitation and humidity.  Will cause
117      some small numerical differences for integrations using pkg/exf/exf_interp.F.
118    o pkg/ctrl/
119      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
120        May be enabled via doPackDiag
121      *  introduce z-scaling of
122         + gradient (doZscalePack) and
123         + control (doZscaleUnpack)
124    o pkg/mdsio/
125      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
126      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
127    
128    checkpoint57b_post
129    o simplify options in diagnostics_fill arguments (remove weird combinations)
130    o fix MNC coordinate variables so that they now contain per-face index
131      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
132      general, EXCH2 grids are only aligned to a "local" coordinate system
133    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
134    o Implement instantaneous output within pkg diagnostics:
135      setting a negative frequency in data.diagnostics produces
136     "snap-shot" output (as opposed to time-average if freq > 0)
137    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
138      NOTE: change ptracer diagnostics name: use 2 characters to work with
139            more than 9 tracers. Add also diagnostics of advect & diffus flux.
140    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
141      becomes the coordinate variable for the 'T' dimension
142    o add CF-style coordinate variables to MNC
143      - just a first cut:  numbers are meaningless on the cubesphere and
144        missing along the T axis but otherwise it works!
145    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
146    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
147    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
148      this is based directly on what the model compute, so that the content of
149      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
150    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
151    o clean up build options files for SunOS, in particular
152      - remove -traditional from xmakedepend
153      - change -xarch=v9 to -xarch=native for f77
154      - restore use of make (not gmake)
155      - add CC=gcc if using g77
156    o changes per discussion of AM, JMC, & EH3 today:
157      - move redundant "grid" variables out of "state" -- in preparation of
158        creating proper CF-style coordinate variables and in recognition
159        that any/all grid variables can be easily copied (eg. w/NCO) from
160        the grid files into any of the other NetCDF files
161      - *always* output grid variables with MDSIO (this will eventually be
162        changed)
163      - output MNC grid file if useMNC is true
164    o every instance of _END_MASTER() has been found and replaced with
165      _END_MASTER( myThid ) in order to satisfy certain picky Sun
166      preprocessors
167    o re-arrange diagnostics pkg initialisation:
168     - allow each package to extend the available diagnostics list
169     - add some checking and fix small problems (multi-threaded, ...)
170     - new S/R diagnostics_fill (replace fill_diagnostics):
171       look through the short list of active diag. (instead of the long list)
172       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
173    
174    checkpoint57a_post
175    o this set of changes restores TAMC compatibility
176      tested for global_ocean.90x40x15 adjoint on trough
177      (what a pain)
178    
179    checkpoint57a_pre
180    o some modifs in tools/build_options for sunos
181    o call ctrl_pack for ctrl at end for optimcycle=0
182    
183    checkpoint57
184    o add horizontal bi-harmonic viscosity for vertical velocity
185      - new parameter viscA4W (defaults to viscA4)
186      - affects only non-hydrostatic code
187      - to be done: no-slip lateral boundary conditions
188    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
189    o implement Implicit Vertical advection for pTracers
190    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
191      (implemented also for implicit vertical diffusion & advection)
192    o OBCS: extend application of tracer open boundary conditions
193      to a strip beyond the boundary of width Olx/Oly
194    o add call monitor to TAF set of required calls (flow directives)
195      and include in natl_box_adjoint
196    o untangle a few ifdefs related to cost, ctrl, autodiff
197      untangel a few ALLOW_ECCO_OPTIMIZATION
198    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
199      (theta2, salt2 in ecco_cost_weights)
200    
201    checkpoint56c_post
202    o OBCS as control variables
203      - update ctrl_ad_diff.list, obcs_ad_diff.list
204      - remove balance of obcs controls from default
205      - fix index bug nobcs in ctrl_init
206      - fix dummy fields filen in ctrl_pack
207      - add dummy weights for obcs
208    o lsopt: comment out fort.94 output
209    o optim:
210      - remove unnecessary header files
211      - adjusted namelists
212      - add xerbla.F to Makefile
213    o exf:
214      - multiple modifications of exf_check_range
215      - unit change in exf_init_runoff from [m/year] to [m/s]
216    o mdsio:
217      - i/o-vector change debugLevel from debLevA to debLevB
218    
219    checkpoint56b_post
220    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
221      is called from DO_THE_MODEL_IO
222      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
223      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
224      - clean up PTRACERS_WRITE_TIMEAVE a little
225    o add another verification experiment that tests both the cfc-pkg and
226      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
227      reactive tendencies treated inline with regular timestepping
228    o testreport previously did a lousy job of comparing small numbers, so
229      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
230      implemented in the little c-progam tmp_cmpnum.c which is embedded in
231      testreport.
232    o ptracers_monitor: bug fix for MPI
233    
234    checkpoint56a_post
235    o GCHEM: finish reorganizating the package
236      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
237        (introduces another 3D-array for each passive tracer, but only if
238        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
239        gchemTendency is not needed because the timestep is done separately)
240      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
241      - GCHEM is now---more or less cleanly---separate from PTRACERS
242      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
243        so clear to me how that should be done in a general way.
244    o CFC: improve formatting of output in CFC_ATMOS
245    o PTRACERS:
246      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
247        that ALL experiments with ptracers enable can be checked. This makes
248        GCHEM_MONITOR obsolete.
249      - include a runtime parameter PTRACERS_monitorFreq that defaults to
250        monitorFreq
251      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
252    o add PTRACERS (PTR0[1-5]) to testreport output
253    o exf_check_range:
254      * default changed to .TRUE.
255      * will check values for niter0 if debLevA, every timestep if debLevB
256      * STOP in exf_check_range if 'out of range'
257      * range chosen generous to allow for potential extema
258      TBD: a version with stricter range
259           permitted range would be runtime parameters
260    o GMredi:
261      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
262      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
263      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
264    o GCHEM:
265      - move call to GCHEM_FORCING_SEP, so that it is now called before
266        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
267      - introduced a useGCHEM runtime flag and applied it everywhere.
268      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
269        this flag is now only visible within GCHEM-pkg routines.
270      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
271        be replaced by a 3D array that is computed before thermodynamics; for
272        this, the tracer ID iTracer had to be included into the parameter list
273        of ptracers_forcing
274      - set up forward_step to call gchem_forcing, that will replace
275        gchem_forcing_int in ptracers_forcing
276      - cleaning up
277    o small cleaning of exch2: remove files that are also in eesupp/src
278    
279    checkpoint56
280    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
281    o mnc: cleanup "full" files--fixes out-of-memory problem
282    o ECCO-GODAE
283      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
284      * fully merged and updated from SIO code
285        windstress sign change affects
286        - exf_inscal_[u/v]stress
287        - sign of xx_tau[u/v] adjustments
288        - signs in cost_scat
289      * ctrl_get_gen: avoid update of tau[u/v] for first few days
290      * natl_box_adjoint updated and compressed
291      * 2-level checkpoint switch added
292        (tested in EXP. 1 of natl_box_adjoint)
293      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
294    o SVD
295      * first complete, non-hacked version for SVD calculations
296      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
297        performed via direct access files admtlm_vector.it????
298        (via ctrl_[un]pack)
299      * optimcycle is used for ARPACK iteration counter
300        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
301      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
302        and add linear transforms where necessary
303      * controls are initial/final SST, SSS (can be extended; need to check
304        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
305    o mdsio: filename info to both stderr, stdout
306    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
307      from sign change
308    
309    checkpoint55j_post
310    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
311      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
312    o add consistent build directories and .cvsignore files to verification
313    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
314    o make all subroutines 30 or less characters in length for certain older
315      compilers to work (a thorough search only turns up two routines in
316      pkg/ptracers)
317    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
318      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
319    
320    checkpoint55i_post
321    o change arrays for total vertical diffusivity (2.D if explicit,
322      3.D if implicit) ; each ptracer uses its own background value.
323    o added mnc/NetCDF output capability to ocn_compon_interf
324      - added bits to verification/cpl_aim+ocn so that it can run on
325        ITRDA and other clusters without the mpirun "-wd" option
326    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
327      configuration
328    o give MNC the ability to create additional files rather than
329      exceeding a specified file size limit "MNC_MAX_FILESIZE"
330      - the default is just less than 2GB which is a practical limit
331        on many systems
332    o Compute the non-local term using either KPP vertical diffusivity (=default)
333       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
334    
335    checkpoint55h_post
336    o add verification test "vermix"
337    o remove all the *_ioinc flags and replace with the single global
338      outputTypesInclusive flag
339    o allow to set a vertical profile of vertical diffusivity for T & S
340    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
341    o useMNC moved from data.mnc to data.pkg
342    
343    checkpoint55g_post
344    o Renaming carbon AD experiments to comply with testreport conventions
345    o Updating adjoint of Held-Suarez hs94.1x64x5
346    o Fixing directives for non-ECCO forward_step, after ECCO directives
347      have been fixed to avoid recomp. of do_oceanic_phys
348      Works well for global_ocean.90x40x15,
349      but recomp. issue remains for carbon
350    o Updating adjoint output for natl_box_adjoint after
351      pkg/ecco has been modified (see taga c55d_post)
352    
353    checkpoint55f_post
354    o rename to timeave_init_fixed
355    
356    checkpoint55e_post
357    o some delicate re-shuffle of store directives to avoid one
358      extra call of do_oceanic_physics
359      affects ecco_the_main_loop.F, do_oceanic_physics.F
360      checkpoint_lev1_directives.h
361    o NB: this may break global_ocean adjoint temporarily,
362      but it is clear how to fix it. Will do later, need this now.
363    
364    checkpoint55d_post
365    o ECCO specific cost function terms (up-to-date with 1x1 runs)
366    o ecco_cost_weights is modified to 1x1 runs
367    o modifs to allow observations to be read in as
368      single file or yearly files
369    o enable to read exf forcing fields as either
370      single file or yearly files (flag useExfYearlyFields)
371    checkpoint55d_pre
372    
373    o switch between 2-level and 3-level checkpointing
374    o add ability of MNC to write local and "partial" (eg. 2D slices where
375      the full 3D field is never actually stored) arrays to NetCDF files
376      with the correct (that is, the complete multi-dimensional) set of
377      array indicies
378      - used in mom_vecinv() to write the diagFreq output
379      - tested (demonstrated) in verification/aim.5l_cs
380    o further mnc-ification
381      - add verification/lab_sea to the list with mnc setups
382      - fix undefined mnc v-names in cd_code
383      - add kpp to mnc output (both snapshot and timeave)
384    o non-hydrostatic code
385      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
386        in calc_gw.F
387      - defaults to viscAh
388      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
389        friction or Leith) in non-hydrostatic mode, as long as there is
390        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
391    o pkg/cost
392      extend simple cost functions to treat time mean quantities
