3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o add saltFlux(+File) forcing capability with periodicExternalForcing
7    o allow to use pkg diagnostics for GM-Redi & ThSIce output
8    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
9    o improvements for the MNC output from DIAGNOSTICS:
10      - correct handling of the unlimitied dimension
11      - all dims now have associated coordinate variables
12      - variables located at U, V, and Corner ("Z") points are now written
13        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
14        *all* data points are output
15    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
16    o added pkg/seaice/seaice_monitor.F
17    o mdsio_readfield.F can now read files visible only to master MPI process.
18    o pkg/seaice: some test code for ice-modified ocean stress
19    o exf_getffields interpolation defaults to bilinear for all scalar forcing
20      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
21      spurious negative numbers for precipitation and humidity.  Will cause
22      some small numerical differences for integrations using pkg/exf/exf_interp.F.
23    o Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
24      May be enabled via doPackDiag
25    
26    checkpoint57b_post
27    o simplify options in diagnostics_fill arguments (remove weird combinations)
28    o fix MNC coordinate variables so that they now contain per-face index
29      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
30      general, EXCH2 grids are only aligned to a "local" coordinate system
31    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
32    o Implement instantaneous output within pkg diagnostics:
33      setting a negative frequency in data.diagnostics produces
34     "snap-shot" output (as opposed to time-average if freq > 0)
35    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
36      NOTE: change ptracer diagnostics name: use 2 characters to work with
37            more than 9 tracers. Add also diagnostics of advect & diffus flux.
38    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
39      becomes the coordinate variable for the 'T' dimension
40    o add CF-style coordinate variables to MNC
41      - just a first cut:  numbers are meaningless on the cubesphere and
42        missing along the T axis but otherwise it works!
43    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
44    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
45    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
46      this is based directly on what the model compute, so that the content of
47      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
48    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
49    o clean up build options files for SunOS, in particular
50      - remove -traditional from xmakedepend
51      - change -xarch=v9 to -xarch=native for f77
52      - restore use of make (not gmake)
53      - add CC=gcc if using g77
54    o changes per discussion of AM, JMC, & EH3 today:
55      - move redundant "grid" variables out of "state" -- in preparation of
56        creating proper CF-style coordinate variables and in recognition
57        that any/all grid variables can be easily copied (eg. w/NCO) from
58        the grid files into any of the other NetCDF files
59      - *always* output grid variables with MDSIO (this will eventually be
60        changed)
61      - output MNC grid file if useMNC is true
62    o every instance of _END_MASTER() has been found and replaced with
63      _END_MASTER( myThid ) in order to satisfy certain picky Sun
64      preprocessors
65    o re-arrange diagnostics pkg initialisation:
66     - allow each package to extend the available diagnostics list
67     - add some checking and fix small problems (multi-threaded, ...)
68     - new S/R diagnostics_fill (replace fill_diagnostics):
69       look through the short list of active diag. (instead of the long list)
70       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
71    
72    checkpoint57a_post
73    o this set of changes restores TAMC compatibility
74      tested for global_ocean.90x40x15 adjoint on trough
75      (what a pain)
76    
77    checkpoint57a_pre
78    o some modifs in tools/build_options for sunos
79    o call ctrl_pack for ctrl at end for optimcycle=0
80    
81    checkpoint57
82    o add horizontal bi-harmonic viscosity for vertical velocity
83      - new parameter viscA4W (defaults to viscA4)
84      - affects only non-hydrostatic code
85      - to be done: no-slip lateral boundary conditions
86    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
87    o implement Implicit Vertical advection for pTracers
88    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
89      (implemented also for implicit vertical diffusion & advection)
90    o OBCS: extend application of tracer open boundary conditions
91      to a strip beyond the boundary of width Olx/Oly
92    o add call monitor to TAF set of required calls (flow directives)
93      and include in natl_box_adjoint
94    o untangle a few ifdefs related to cost, ctrl, autodiff
95      untangel a few ALLOW_ECCO_OPTIMIZATION
96    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
97      (theta2, salt2 in ecco_cost_weights)
98    
99    checkpoint56c_post
100    o OBCS as control variables
101      - update ctrl_ad_diff.list, obcs_ad_diff.list
102      - remove balance of obcs controls from default
103      - fix index bug nobcs in ctrl_init
104      - fix dummy fields filen in ctrl_pack
105      - add dummy weights for obcs
106    o lsopt: comment out fort.94 output
107    o optim:
108      - remove unnecessary header files
109      - adjusted namelists
110      - add xerbla.F to Makefile
111    o exf:
112      - multiple modifications of exf_check_range
113      - unit change in exf_init_runoff from [m/year] to [m/s]
114    o mdsio:
115      - i/o-vector change debugLevel from debLevA to debLevB
116    
117    checkpoint56b_post
118    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
119      is called from DO_THE_MODEL_IO
120      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
121      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
122      - clean up PTRACERS_WRITE_TIMEAVE a little
123    o add another verification experiment that tests both the cfc-pkg and
124      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
125      reactive tendencies treated inline with regular timestepping
126    o testreport previously did a lousy job of comparing small numbers, so
127      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
128      implemented in the little c-progam tmp_cmpnum.c which is embedded in
129      testreport.
130    o ptracers_monitor: bug fix for MPI
131    
132    checkpoint56a_post
133    o GCHEM: finish reorganizating the package
134      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
135        (introduces another 3D-array for each passive tracer, but only if
136        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
137        gchemTendency is not needed because the timestep is done separately)
138      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
139      - GCHEM is now---more or less cleanly---separate from PTRACERS
140      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
141        so clear to me how that should be done in a general way.
142    o CFC: improve formatting of output in CFC_ATMOS
143    o PTRACERS:
144      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
145        that ALL experiments with ptracers enable can be checked. This makes
146        GCHEM_MONITOR obsolete.
147      - include a runtime parameter PTRACERS_monitorFreq that defaults to
148        monitorFreq
149      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
150    o add PTRACERS (PTR0[1-5]) to testreport output
151    o exf_check_range:
152      * default changed to .TRUE.
153      * will check values for niter0 if debLevA, every timestep if debLevB
154      * STOP in exf_check_range if 'out of range'
155      * range chosen generous to allow for potential extema
156      TBD: a version with stricter range
157           permitted range would be runtime parameters
158    o GMredi:
159      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
160      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
161      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
162    o GCHEM:
163      - move call to GCHEM_FORCING_SEP, so that it is now called before
164        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
165      - introduced a useGCHEM runtime flag and applied it everywhere.
166      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
167        this flag is now only visible within GCHEM-pkg routines.
168      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
169        be replaced by a 3D array that is computed before thermodynamics; for
170        this, the tracer ID iTracer had to be included into the parameter list
171        of ptracers_forcing
172      - set up forward_step to call gchem_forcing, that will replace
173        gchem_forcing_int in ptracers_forcing
174      - cleaning up
175    o small cleaning of exch2: remove files that are also in eesupp/src
176    
177    checkpoint56
178    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
179    o mnc: cleanup "full" files--fixes out-of-memory problem
180    o ECCO-GODAE
181      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
182      * fully merged and updated from SIO code
183        windstress sign change affects
184        - exf_inscal_[u/v]stress
185        - sign of xx_tau[u/v] adjustments
186        - signs in cost_scat
187      * ctrl_get_gen: avoid update of tau[u/v] for first few days
188      * natl_box_adjoint updated and compressed
189      * 2-level checkpoint switch added
190        (tested in EXP. 1 of natl_box_adjoint)
191      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
192    o SVD
193      * first complete, non-hacked version for SVD calculations
194      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
195        performed via direct access files admtlm_vector.it????
196        (via ctrl_[un]pack)
197      * optimcycle is used for ARPACK iteration counter
198        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
199      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
200        and add linear transforms where necessary
201      * controls are initial/final SST, SSS (can be extended; need to check
202        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
203    o mdsio: filename info to both stderr, stdout
204    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
205      from sign change
206    
207    checkpoint55j_post
208    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
209      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
210    o add consistent build directories and .cvsignore files to verification
211    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
212    o make all subroutines 30 or less characters in length for certain older
213      compilers to work (a thorough search only turns up two routines in
214      pkg/ptracers)
215    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
216      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
217    
218    checkpoint55i_post
219    o change arrays for total vertical diffusivity (2.D if explicit,
220      3.D if implicit) ; each ptracer uses its own background value.
221    o added mnc/NetCDF output capability to ocn_compon_interf
222      - added bits to verification/cpl_aim+ocn so that it can run on
223        ITRDA and other clusters without the mpirun "-wd" option
224    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
225      configuration
226    o give MNC the ability to create additional files rather than
227      exceeding a specified file size limit "MNC_MAX_FILESIZE"
228      - the default is just less than 2GB which is a practical limit
229        on many systems
230    o Compute the non-local term using either KPP vertical diffusivity (=default)
231       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
232    
233    checkpoint55h_post
234    o add verification test "vermix"
235    o remove all the *_ioinc flags and replace with the single global
236      outputTypesInclusive flag
237    o allow to set a vertical profile of vertical diffusivity for T & S
238    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
239    o useMNC moved from data.mnc to data.pkg
240    
241    checkpoint55g_post
242    o Renaming carbon AD experiments to comply with testreport conventions
243    o Updating adjoint of Held-Suarez hs94.1x64x5
244    o Fixing directives for non-ECCO forward_step, after ECCO directives
245      have been fixed to avoid recomp. of do_oceanic_phys
246      Works well for global_ocean.90x40x15,
247      but recomp. issue remains for carbon
248    o Updating adjoint output for natl_box_adjoint after
249      pkg/ecco has been modified (see taga c55d_post)
250    
251    checkpoint55f_post
252    o rename to timeave_init_fixed
253    
254    checkpoint55e_post
255    o some delicate re-shuffle of store directives to avoid one
256      extra call of do_oceanic_physics
257      affects ecco_the_main_loop.F, do_oceanic_physics.F
258      checkpoint_lev1_directives.h
259    o NB: this may break global_ocean adjoint temporarily,
260      but it is clear how to fix it. Will do later, need this now.
261    
262    checkpoint55d_post
263    o ECCO specific cost function terms (up-to-date with 1x1 runs)
264    o ecco_cost_weights is modified to 1x1 runs
265    o modifs to allow observations to be read in as
266      single file or yearly files
267    o enable to read exf forcing fields as either
268      single file or yearly files (flag useExfYearlyFields)
269    checkpoint55d_pre
270    
271    o switch between 2-level and 3-level checkpointing
272    o add ability of MNC to write local and "partial" (eg. 2D slices where
273      the full 3D field is never actually stored) arrays to NetCDF files
274      with the correct (that is, the complete multi-dimensional) set of
275      array indicies
276      - used in mom_vecinv() to write the diagFreq output
277      - tested (demonstrated) in verification/aim.5l_cs
278    o further mnc-ification
279      - add verification/lab_sea to the list with mnc setups
280      - fix undefined mnc v-names in cd_code
281      - add kpp to mnc output (both snapshot and timeave)
282    o non-hydrostatic code
283      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
284        in calc_gw.F
285      - defaults to viscAh
286      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
287        friction or Leith) in non-hydrostatic mode, as long as there is
288        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
289    o pkg/cost
290      extend simple cost functions to treat time mean quantities
291      (T,U,V) via cost_accumulate_state from cost_tile
292    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
293        be 2 times larger than the minimum size the advection scheme requires.
294        now get a perfect conservation of salt in advect_cs test-exp (updated)
295    o GGL90 (Gaspar's TKE mixed layer)
296      - add horizontal diffusion of TKE, requires exchanges in
297        do_fields_blocking_exchanges, horizontal diffusivity is zero by
298        default. In OPA there is no horizontal diffusion of TKE but the
299        mixing coefficients are computed from a horizontal average of TKE of
300        6 points or so. I think that diffusion has a little more physical
301        justification.
302      - clean up ggl90_calc in the hope of reducing memory usage (this hope
303        was in vain)
304      - mask tke-variable in ggl90_init
305    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
306    o fix biharmonic diffusion on CS-grid.
307    o more obcs stuff
308      - added obcs_external_fields_load as an alternative to the EXF-pkg option
309        for reading boundary values. This routine is called from
310        obcs_prescribe_read
311      - updated obcs_check
312      - changed sponge layer relaxation parameter units for days to seconds
313      - turned off sponge layer by default
314      - changed argument list of OBCS_CALC to myTime+deltaTclock
315      - fixed about 35 bugs in obcs_external_fields_load
316    
317    checkpoint55c_post
318    o obcs stuff
319      - new runtime flags useOBCSprescribe, useOBCSbalance
320      - re-arranged obcs_calc
321      - moved exf_getobcs to obcs_prescibe_read
322        obcs_prescibe_read is called after ORLANSKI stuff
323        and independent of it (executable can contain all).
324      - updated obcs_check
325      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
326        These may be necessary only if tangential velocities are
327        prescribed at OB, not sure, needs testing.
328    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
329      which simplifies the calls and passes the ifc check-bounds test
330    
331    checkpoint55b_post
332    o add a 2D scalar, Z location, exchange_2 routine.
333    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
334      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
335      affects advect_cs results (for the wrong reason): update output.txt
336    o use a more standard discretization for biharmonic viscosity ;
337     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
338      affects results of dome set-up: update output.txt
339    o fix gad_advection.F (CubedSphere part), back to version 1.23
340    o fix bug in mom_vi_del2uv.F (CubedSphere part).
341    
342    checkpoint55a_post
343    o merged code to
344      * prescribe/read time-dependent open boundaries
345        (works in conjunction with exf, cal)
346      * sponge layer code for open boundaries
347      * each boundary N/S/E/W now has its own CPP option
348        (healthy for the adjoint)
349    
350    checkpoint55
351    o up-to-date adjoint of previous breaks
352      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
353      - global_ocean_ebm: adjoint still needs fix (TLM ok)
354      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
355      - carbon: * remove tr1-related adjoint verification
356                * add ptracer as control variable
357    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
358      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
359    
360    checkpoint54f_post
361    o in verification/carbin/ remove experiment related to
362      ALLOW_PASSIVE_TRACER (array tr1 etc)
363      code_ad/ input_ad/ results_ad
364    
365    o add two new packages
366      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
367        + subject to optimization (memory)
368      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
369        + subject to reordering (many GOTOs in the original code)
370        + so far opps is called for every (i,j) point, and then operates in
371          the vertical; one may want to reorder the scheme in order operate in
372          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
373          fields)
374    o overhaul of IO so that we now have flags for MDSIO and/or MNC
375      - all verification tests compile and run with linux_ia32_g77
376      - defaults are compatible with current input files--nothing
377        should change if you were not previously using MNC
378      - MNC output has been added in numerous places (eg. timeave)
379        but there are still a few writes not yet do-able with MNC
380        (this is in progress)
381      - flags now allow for either/or/both use of MDSIO and MNC and
382        documentation will soon follow
383      - numerous small formatting cleanups for ProTeX
384    o add version info (via BUILD_INFO.h) to MNC and stdout
385    
386    checkpoint54e_post
387    o add two new packages
388      - pp81 (Packanowski and Philander, 1981), Richardson number and
389        stratification dependent mixing
390      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
391      - these scheme operate in a similar manner as KPP (without ghat, of
392        course), however there is only one diffusivity that is used for both
393        temperature and salinity (and passive tracers)ç
394    o add offline package
395    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
396      provided by Stephanie Dutkiewicz
397    o genmake2: add ability to search for C compilers and cleanup test output
398      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
399    
400    checkpoint54d_post
401    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
402    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
403      leading to additional shift by 5 days each year of integration
404       (i.e. leading to considerable offset over the years)
405    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
406    o start with no AB and no initial filtering (staggerTimeStep):
407      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
408    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
409      (external loading & cpl import/export stay in forward_step.F)
410    o update coupling interface to work with new staggerTimeStep
411    o change MDSIO ptracers_pickup.
412    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
413    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
414    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
415    
416    checkpoint54c_post
417    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
418      this affects (truncation error) output.txt of test-exp:
419       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
420    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
421    o change Qnet to always be the net heat flux, (+upward).
422      affects (truncation error) output of natl_box exp.: updated
423    o define the max number of passive tracers in PTRACERS_SIZE.h
424    o start to test mnc routinely in exp0
425    o add sea-ice loading (sIceLoad) as a new forcing field.
426    
427    checkpoint54b_post
428    o add testreport "-j JOBS" option for parallel builds (tested and pretty
429       impressive on Altix and Opteron systems)
430    o diagnostics can now write NetCDF files through the mnc package
431    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
432    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
433  o staggerTimeStep & NLFS: rescale T & S surface tendencies.  o staggerTimeStep & NLFS: rescale T & S surface tendencies.
434    affects (truncation error) output of lab_sea & natl_box exp.: updated    affects (truncation error) output of lab_sea & natl_box exp.: updated
435  o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)  o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
