3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o change MNC-flags default value: true when useMNC=TRUE
7    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
8      the ability (off by default) to read the grid information using MNC
9    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
10    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
11    o do snap-shot diagnostics at the middle of the time-interval (instead of
12      at the end).
13    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
14      new test for AIM with thSIce + slab-ocean
15    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
16    o move state variable diagnostics to the beginning of the time step ;
17      (note: still needs some work specially for snap-shot diagnostics)
18      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
19    
20    checkpoint57c_post
21    o Change testing option (-ieee) to get closer agreement between g77 & ifort
22    o generate new output.txt files on faulks with g77 & the new -ieee option
23    checkpoint57c_pre
24    
25    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
26      update output.txt of exp. global_ocean.90x40x15
27    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
28      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
29    o add saltFlux(+File) forcing capability with periodicExternalForcing
30    o allow to use pkg diagnostics for GM-Redi & ThSIce output
31    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
32    o improvements for the MNC output from DIAGNOSTICS:
33      - correct handling of the unlimitied dimension
34      - all dims now have associated coordinate variables
35      - variables located at U, V, and Corner ("Z") points are now written
36        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
37        *all* data points are output
38    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
39    o added pkg/seaice/seaice_monitor.F
40    o mdsio_readfield.F can now read files visible only to master MPI process.
41    o pkg/seaice: some test code for ice-modified ocean stress
42    o exf_getffields interpolation defaults to bilinear for all scalar forcing
43      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
44      spurious negative numbers for precipitation and humidity.  Will cause
45      some small numerical differences for integrations using pkg/exf/exf_interp.F.
46    o pkg/ctrl/
47      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
48        May be enabled via doPackDiag
49      *  introduce z-scaling of
50         + gradient (doZscalePack) and
51         + control (doZscaleUnpack)
52    o pkg/mdsio/
53      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
54      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
55    
56    checkpoint57b_post
57    o simplify options in diagnostics_fill arguments (remove weird combinations)
58    o fix MNC coordinate variables so that they now contain per-face index
59      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
60      general, EXCH2 grids are only aligned to a "local" coordinate system
61    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
62    o Implement instantaneous output within pkg diagnostics:
63      setting a negative frequency in data.diagnostics produces
64     "snap-shot" output (as opposed to time-average if freq > 0)
65    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
66      NOTE: change ptracer diagnostics name: use 2 characters to work with
67            more than 9 tracers. Add also diagnostics of advect & diffus flux.
68    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
69      becomes the coordinate variable for the 'T' dimension
70    o add CF-style coordinate variables to MNC
71      - just a first cut:  numbers are meaningless on the cubesphere and
72        missing along the T axis but otherwise it works!
73    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
74    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
75    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
76      this is based directly on what the model compute, so that the content of
77      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
78    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
79    o clean up build options files for SunOS, in particular
80      - remove -traditional from xmakedepend
81      - change -xarch=v9 to -xarch=native for f77
82      - restore use of make (not gmake)
83      - add CC=gcc if using g77
84    o changes per discussion of AM, JMC, & EH3 today:
85      - move redundant "grid" variables out of "state" -- in preparation of
86        creating proper CF-style coordinate variables and in recognition
87        that any/all grid variables can be easily copied (eg. w/NCO) from
88        the grid files into any of the other NetCDF files
89      - *always* output grid variables with MDSIO (this will eventually be
90        changed)
91      - output MNC grid file if useMNC is true
92    o every instance of _END_MASTER() has been found and replaced with
93      _END_MASTER( myThid ) in order to satisfy certain picky Sun
94      preprocessors
95    o re-arrange diagnostics pkg initialisation:
96     - allow each package to extend the available diagnostics list
97     - add some checking and fix small problems (multi-threaded, ...)
98     - new S/R diagnostics_fill (replace fill_diagnostics):
99       look through the short list of active diag. (instead of the long list)
100       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
101    
102    checkpoint57a_post
103    o this set of changes restores TAMC compatibility
104      tested for global_ocean.90x40x15 adjoint on trough
105      (what a pain)
106    
107    checkpoint57a_pre
108    o some modifs in tools/build_options for sunos
109    o call ctrl_pack for ctrl at end for optimcycle=0
110    
111    checkpoint57
112    o add horizontal bi-harmonic viscosity for vertical velocity
113      - new parameter viscA4W (defaults to viscA4)
114      - affects only non-hydrostatic code
115      - to be done: no-slip lateral boundary conditions
116    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
117    o implement Implicit Vertical advection for pTracers
118    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
119      (implemented also for implicit vertical diffusion & advection)
120    o OBCS: extend application of tracer open boundary conditions
121      to a strip beyond the boundary of width Olx/Oly
122    o add call monitor to TAF set of required calls (flow directives)
123      and include in natl_box_adjoint
124    o untangle a few ifdefs related to cost, ctrl, autodiff
125      untangel a few ALLOW_ECCO_OPTIMIZATION
126    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
127      (theta2, salt2 in ecco_cost_weights)
128    
129    checkpoint56c_post
130    o OBCS as control variables
131      - update ctrl_ad_diff.list, obcs_ad_diff.list
132      - remove balance of obcs controls from default
133      - fix index bug nobcs in ctrl_init
134      - fix dummy fields filen in ctrl_pack
135      - add dummy weights for obcs
136    o lsopt: comment out fort.94 output
137    o optim:
138      - remove unnecessary header files
139      - adjusted namelists
140      - add xerbla.F to Makefile
141    o exf:
142      - multiple modifications of exf_check_range
143      - unit change in exf_init_runoff from [m/year] to [m/s]
144    o mdsio:
145      - i/o-vector change debugLevel from debLevA to debLevB
146    
147    checkpoint56b_post
148    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
149      is called from DO_THE_MODEL_IO
150      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
151      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
152      - clean up PTRACERS_WRITE_TIMEAVE a little
153    o add another verification experiment that tests both the cfc-pkg and
154      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
155      reactive tendencies treated inline with regular timestepping
156    o testreport previously did a lousy job of comparing small numbers, so
157      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
158      implemented in the little c-progam tmp_cmpnum.c which is embedded in
159      testreport.
160    o ptracers_monitor: bug fix for MPI
161    
162    checkpoint56a_post
163    o GCHEM: finish reorganizating the package
164      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
165        (introduces another 3D-array for each passive tracer, but only if
166        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
167        gchemTendency is not needed because the timestep is done separately)
168      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
169      - GCHEM is now---more or less cleanly---separate from PTRACERS
170      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
171        so clear to me how that should be done in a general way.
172    o CFC: improve formatting of output in CFC_ATMOS
173    o PTRACERS:
174      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
175        that ALL experiments with ptracers enable can be checked. This makes
176        GCHEM_MONITOR obsolete.
177      - include a runtime parameter PTRACERS_monitorFreq that defaults to
178        monitorFreq
179      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
180    o add PTRACERS (PTR0[1-5]) to testreport output
181    o exf_check_range:
182      * default changed to .TRUE.
183      * will check values for niter0 if debLevA, every timestep if debLevB
184      * STOP in exf_check_range if 'out of range'
185      * range chosen generous to allow for potential extema
186      TBD: a version with stricter range
187           permitted range would be runtime parameters
188    o GMredi:
189      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
190      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
191      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
192    o GCHEM:
193      - move call to GCHEM_FORCING_SEP, so that it is now called before
194        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
195      - introduced a useGCHEM runtime flag and applied it everywhere.
196      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
197        this flag is now only visible within GCHEM-pkg routines.
198      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
199        be replaced by a 3D array that is computed before thermodynamics; for
200        this, the tracer ID iTracer had to be included into the parameter list
201        of ptracers_forcing
202      - set up forward_step to call gchem_forcing, that will replace
203        gchem_forcing_int in ptracers_forcing
204      - cleaning up
205    o small cleaning of exch2: remove files that are also in eesupp/src
206    
207    checkpoint56
208    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
209    o mnc: cleanup "full" files--fixes out-of-memory problem
210    o ECCO-GODAE
211      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
212      * fully merged and updated from SIO code
213        windstress sign change affects
214        - exf_inscal_[u/v]stress
215        - sign of xx_tau[u/v] adjustments
216        - signs in cost_scat
217      * ctrl_get_gen: avoid update of tau[u/v] for first few days
218      * natl_box_adjoint updated and compressed
219      * 2-level checkpoint switch added
220        (tested in EXP. 1 of natl_box_adjoint)
221      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
222    o SVD
223      * first complete, non-hacked version for SVD calculations
224      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
225        performed via direct access files admtlm_vector.it????
226        (via ctrl_[un]pack)
227      * optimcycle is used for ARPACK iteration counter
228        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
229      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
230        and add linear transforms where necessary
231      * controls are initial/final SST, SSS (can be extended; need to check
232        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
233    o mdsio: filename info to both stderr, stdout
234    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
235      from sign change
236    
237    checkpoint55j_post
238    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
239      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
240    o add consistent build directories and .cvsignore files to verification
241    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
242    o make all subroutines 30 or less characters in length for certain older
243      compilers to work (a thorough search only turns up two routines in
244      pkg/ptracers)
245    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
246      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
247    
248    checkpoint55i_post
249    o change arrays for total vertical diffusivity (2.D if explicit,
250      3.D if implicit) ; each ptracer uses its own background value.
251    o added mnc/NetCDF output capability to ocn_compon_interf
252      - added bits to verification/cpl_aim+ocn so that it can run on
253        ITRDA and other clusters without the mpirun "-wd" option
254    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
255      configuration
256    o give MNC the ability to create additional files rather than
257      exceeding a specified file size limit "MNC_MAX_FILESIZE"
258      - the default is just less than 2GB which is a practical limit
259        on many systems
260    o Compute the non-local term using either KPP vertical diffusivity (=default)
261       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
262    
263    checkpoint55h_post
264    o add verification test "vermix"
265    o remove all the *_ioinc flags and replace with the single global
266      outputTypesInclusive flag
267    o allow to set a vertical profile of vertical diffusivity for T & S
268    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
269    o useMNC moved from data.mnc to data.pkg
270    
271    checkpoint55g_post
272    o Renaming carbon AD experiments to comply with testreport conventions
273    o Updating adjoint of Held-Suarez hs94.1x64x5
274    o Fixing directives for non-ECCO forward_step, after ECCO directives
275      have been fixed to avoid recomp. of do_oceanic_phys
276      Works well for global_ocean.90x40x15,
277      but recomp. issue remains for carbon
278    o Updating adjoint output for natl_box_adjoint after
279      pkg/ecco has been modified (see taga c55d_post)
280    
281    checkpoint55f_post
282    o rename to timeave_init_fixed
283    
284    checkpoint55e_post
285    o some delicate re-shuffle of store directives to avoid one
286      extra call of do_oceanic_physics
287      affects ecco_the_main_loop.F, do_oceanic_physics.F
288      checkpoint_lev1_directives.h
289    o NB: this may break global_ocean adjoint temporarily,
290      but it is clear how to fix it. Will do later, need this now.
291    
292    checkpoint55d_post
293    o ECCO specific cost function terms (up-to-date with 1x1 runs)
294    o ecco_cost_weights is modified to 1x1 runs
295    o modifs to allow observations to be read in as
296      single file or yearly files
297    o enable to read exf forcing fields as either
298      single file or yearly files (flag useExfYearlyFields)
299    checkpoint55d_pre
300    
301    o switch between 2-level and 3-level checkpointing
302    o add ability of MNC to write local and "partial" (eg. 2D slices where
303      the full 3D field is never actually stored) arrays to NetCDF files
304      with the correct (that is, the complete multi-dimensional) set of
305      array indicies
306      - used in mom_vecinv() to write the diagFreq output
307      - tested (demonstrated) in verification/aim.5l_cs
308    o further mnc-ification
309      - add verification/lab_sea to the list with mnc setups
310      - fix undefined mnc v-names in cd_code
311      - add kpp to mnc output (both snapshot and timeave)
312    o non-hydrostatic code
313      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
314        in calc_gw.F
315      - defaults to viscAh
316      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
317        friction or Leith) in non-hydrostatic mode, as long as there is
318        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
319    o pkg/cost
320      extend simple cost functions to treat time mean quantities
321      (T,U,V) via cost_accumulate_state from cost_tile
322    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
323        be 2 times larger than the minimum size the advection scheme requires.
324        now get a perfect conservation of salt in advect_cs test-exp (updated)
325    o GGL90 (Gaspar's TKE mixed layer)
326      - add horizontal diffusion of TKE, requires exchanges in
327        do_fields_blocking_exchanges, horizontal diffusivity is zero by
328        default. In OPA there is no horizontal diffusion of TKE but the
329        mixing coefficients are computed from a horizontal average of TKE of
330        6 points or so. I think that diffusion has a little more physical
331        justification.
332      - clean up ggl90_calc in the hope of reducing memory usage (this hope
333        was in vain)
334      - mask tke-variable in ggl90_init
335    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
336    o fix biharmonic diffusion on CS-grid.
337    o more obcs stuff
338      - added obcs_external_fields_load as an alternative to the EXF-pkg option
339        for reading boundary values. This routine is called from
340        obcs_prescribe_read
341      - updated obcs_check
342      - changed sponge layer relaxation parameter units for days to seconds
343      - turned off sponge layer by default
344      - changed argument list of OBCS_CALC to myTime+deltaTclock
345      - fixed about 35 bugs in obcs_external_fields_load
346    
347    checkpoint55c_post
348    o obcs stuff
349      - new runtime flags useOBCSprescribe, useOBCSbalance
350      - re-arranged obcs_calc
351      - moved exf_getobcs to obcs_prescibe_read
352        obcs_prescibe_read is called after ORLANSKI stuff
353        and independent of it (executable can contain all).
354      - updated obcs_check
355      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
356        These may be necessary only if tangential velocities are
357        prescribed at OB, not sure, needs testing.
358    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
359      which simplifies the calls and passes the ifc check-bounds test
360    
361    checkpoint55b_post
362    o add a 2D scalar, Z location, exchange_2 routine.
363    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
364      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
365      affects advect_cs results (for the wrong reason): update output.txt
366    o use a more standard discretization for biharmonic viscosity ;
367     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
368      affects results of dome set-up: update output.txt
369    o fix gad_advection.F (CubedSphere part), back to version 1.23
370    o fix bug in mom_vi_del2uv.F (CubedSphere part).
371    
372    checkpoint55a_post
373    o merged code to
374      * prescribe/read time-dependent open boundaries
375        (works in conjunction with exf, cal)
376      * sponge layer code for open boundaries
377      * each boundary N/S/E/W now has its own CPP option
378        (healthy for the adjoint)
379    
380    checkpoint55
381    o up-to-date adjoint of previous breaks
382      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
383      - global_ocean_ebm: adjoint still needs fix (TLM ok)
384      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
385      - carbon: * remove tr1-related adjoint verification
386                * add ptracer as control variable
387    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
388      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
389    
390    checkpoint54f_post
391    o in verification/carbin/ remove experiment related to
392      ALLOW_PASSIVE_TRACER (array tr1 etc)
393      code_ad/ input_ad/ results_ad
394    
395    o add two new packages
396      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
397        + subject to optimization (memory)
398      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
399        + subject to reordering (many GOTOs in the original code)
400        + so far opps is called for every (i,j) point, and then operates in
401          the vertical; one may want to reorder the scheme in order operate in
402          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
403          fields)
404    o overhaul of IO so that we now have flags for MDSIO and/or MNC
405      - all verification tests compile and run with linux_ia32_g77
406      - defaults are compatible with current input files--nothing
407        should change if you were not previously using MNC
408      - MNC output has been added in numerous places (eg. timeave)
409        but there are still a few writes not yet do-able with MNC
410        (this is in progress)
411      - flags now allow for either/or/both use of MDSIO and MNC and
412        documentation will soon follow
413      - numerous small formatting cleanups for ProTeX
414    o add version info (via BUILD_INFO.h) to MNC and stdout
415    
416    checkpoint54e_post
417    o add two new packages
418      - pp81 (Packanowski and Philander, 1981), Richardson number and
419        stratification dependent mixing
420      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
421      - these scheme operate in a similar manner as KPP (without ghat, of
422        course), however there is only one diffusivity that is used for both
423        temperature and salinity (and passive tracers)ç
424    o add offline package
425    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
426      provided by Stephanie Dutkiewicz
427    o genmake2: add ability to search for C compilers and cleanup test output
428      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
429    
430    checkpoint54d_post
431    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
432    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
433      leading to additional shift by 5 days each year of integration
434       (i.e. leading to considerable offset over the years)
435  o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep  o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
436  o start with no AB and no initial filtering (staggerTimeStep):  o start with no AB and no initial filtering (staggerTimeStep):
437    change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5    change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
