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 pkg/ctrl/
24      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
25        May be enabled via doPackDiag
26      *  introduce z-scaling of
27         + gradient (doZscalePack) and
28         + control (doZscaleUnpack)
29    o pkg/mdsio/
30      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
31      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
32    
33    checkpoint57b_post
34    o simplify options in diagnostics_fill arguments (remove weird combinations)
35    o fix MNC coordinate variables so that they now contain per-face index
36      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
37      general, EXCH2 grids are only aligned to a "local" coordinate system
38    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
39    o Implement instantaneous output within pkg diagnostics:
40      setting a negative frequency in data.diagnostics produces
41     "snap-shot" output (as opposed to time-average if freq > 0)
42    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
43      NOTE: change ptracer diagnostics name: use 2 characters to work with
44            more than 9 tracers. Add also diagnostics of advect & diffus flux.
45    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
46      becomes the coordinate variable for the 'T' dimension
47    o add CF-style coordinate variables to MNC
48      - just a first cut:  numbers are meaningless on the cubesphere and
49        missing along the T axis but otherwise it works!
50    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
51    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
52    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
53      this is based directly on what the model compute, so that the content of
54      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
55    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
56    o clean up build options files for SunOS, in particular
57      - remove -traditional from xmakedepend
58      - change -xarch=v9 to -xarch=native for f77
59      - restore use of make (not gmake)
60      - add CC=gcc if using g77
61    o changes per discussion of AM, JMC, & EH3 today:
62      - move redundant "grid" variables out of "state" -- in preparation of
63        creating proper CF-style coordinate variables and in recognition
64        that any/all grid variables can be easily copied (eg. w/NCO) from
65        the grid files into any of the other NetCDF files
66      - *always* output grid variables with MDSIO (this will eventually be
67        changed)
68      - output MNC grid file if useMNC is true
69    o every instance of _END_MASTER() has been found and replaced with
70      _END_MASTER( myThid ) in order to satisfy certain picky Sun
71      preprocessors
72    o re-arrange diagnostics pkg initialisation:
73     - allow each package to extend the available diagnostics list
74     - add some checking and fix small problems (multi-threaded, ...)
75     - new S/R diagnostics_fill (replace fill_diagnostics):
76       look through the short list of active diag. (instead of the long list)
77       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
78    
79    checkpoint57a_post
80    o this set of changes restores TAMC compatibility
81      tested for global_ocean.90x40x15 adjoint on trough
82      (what a pain)
83    
84    checkpoint57a_pre
85    o some modifs in tools/build_options for sunos
86    o call ctrl_pack for ctrl at end for optimcycle=0
87    
88    checkpoint57
89    o add horizontal bi-harmonic viscosity for vertical velocity
90      - new parameter viscA4W (defaults to viscA4)
91      - affects only non-hydrostatic code
92      - to be done: no-slip lateral boundary conditions
93    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
94    o implement Implicit Vertical advection for pTracers
95    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
96      (implemented also for implicit vertical diffusion & advection)
97    o OBCS: extend application of tracer open boundary conditions
98      to a strip beyond the boundary of width Olx/Oly
99    o add call monitor to TAF set of required calls (flow directives)
100      and include in natl_box_adjoint
101    o untangle a few ifdefs related to cost, ctrl, autodiff
102      untangel a few ALLOW_ECCO_OPTIMIZATION
103    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
104      (theta2, salt2 in ecco_cost_weights)
105    
106    checkpoint56c_post
107    o OBCS as control variables
108      - update ctrl_ad_diff.list, obcs_ad_diff.list
109      - remove balance of obcs controls from default
110      - fix index bug nobcs in ctrl_init
111      - fix dummy fields filen in ctrl_pack
112      - add dummy weights for obcs
113    o lsopt: comment out fort.94 output
114    o optim:
115      - remove unnecessary header files
116      - adjusted namelists
117      - add xerbla.F to Makefile
118    o exf:
119      - multiple modifications of exf_check_range
120      - unit change in exf_init_runoff from [m/year] to [m/s]
121    o mdsio:
122      - i/o-vector change debugLevel from debLevA to debLevB
123    
124    checkpoint56b_post
125    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
126      is called from DO_THE_MODEL_IO
127      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
128      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
129      - clean up PTRACERS_WRITE_TIMEAVE a little
130    o add another verification experiment that tests both the cfc-pkg and
131      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
132      reactive tendencies treated inline with regular timestepping
133    o testreport previously did a lousy job of comparing small numbers, so
134      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
135      implemented in the little c-progam tmp_cmpnum.c which is embedded in
136      testreport.
137    o ptracers_monitor: bug fix for MPI
138    
139    checkpoint56a_post
140    o GCHEM: finish reorganizating the package
141      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
142        (introduces another 3D-array for each passive tracer, but only if
143        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
144        gchemTendency is not needed because the timestep is done separately)
145      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
146      - GCHEM is now---more or less cleanly---separate from PTRACERS
147      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
148        so clear to me how that should be done in a general way.
149    o CFC: improve formatting of output in CFC_ATMOS
150    o PTRACERS:
151      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
152        that ALL experiments with ptracers enable can be checked. This makes
153        GCHEM_MONITOR obsolete.
154      - include a runtime parameter PTRACERS_monitorFreq that defaults to
155        monitorFreq
156      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
157    o add PTRACERS (PTR0[1-5]) to testreport output
158    o exf_check_range:
159      * default changed to .TRUE.
160      * will check values for niter0 if debLevA, every timestep if debLevB
161      * STOP in exf_check_range if 'out of range'
162      * range chosen generous to allow for potential extema
163      TBD: a version with stricter range
164           permitted range would be runtime parameters
165    o GMredi:
166      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
167      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
168      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
169    o GCHEM:
170      - move call to GCHEM_FORCING_SEP, so that it is now called before
171        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
172      - introduced a useGCHEM runtime flag and applied it everywhere.
173      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
174        this flag is now only visible within GCHEM-pkg routines.
175      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
176        be replaced by a 3D array that is computed before thermodynamics; for
177        this, the tracer ID iTracer had to be included into the parameter list
178        of ptracers_forcing
179      - set up forward_step to call gchem_forcing, that will replace
180        gchem_forcing_int in ptracers_forcing
181      - cleaning up
182    o small cleaning of exch2: remove files that are also in eesupp/src
183    
184    checkpoint56
185    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
186    o mnc: cleanup "full" files--fixes out-of-memory problem
187    o ECCO-GODAE
188      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
189      * fully merged and updated from SIO code
190        windstress sign change affects
191        - exf_inscal_[u/v]stress
192        - sign of xx_tau[u/v] adjustments
193        - signs in cost_scat
194      * ctrl_get_gen: avoid update of tau[u/v] for first few days
195      * natl_box_adjoint updated and compressed
196      * 2-level checkpoint switch added
197        (tested in EXP. 1 of natl_box_adjoint)
198      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
199    o SVD
200      * first complete, non-hacked version for SVD calculations
201      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
202        performed via direct access files admtlm_vector.it????
203        (via ctrl_[un]pack)
204      * optimcycle is used for ARPACK iteration counter
205        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
206      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
207        and add linear transforms where necessary
208      * controls are initial/final SST, SSS (can be extended; need to check
209        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
210    o mdsio: filename info to both stderr, stdout
211    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
212      from sign change
213    
214    checkpoint55j_post
215    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
216      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
217    o add consistent build directories and .cvsignore files to verification
218    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
219    o make all subroutines 30 or less characters in length for certain older
220      compilers to work (a thorough search only turns up two routines in
221      pkg/ptracers)
222    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
223      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
224    
225    checkpoint55i_post
226    o change arrays for total vertical diffusivity (2.D if explicit,
227      3.D if implicit) ; each ptracer uses its own background value.
228    o added mnc/NetCDF output capability to ocn_compon_interf
229      - added bits to verification/cpl_aim+ocn so that it can run on
230        ITRDA and other clusters without the mpirun "-wd" option
231    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
232      configuration
233    o give MNC the ability to create additional files rather than
234      exceeding a specified file size limit "MNC_MAX_FILESIZE"
235      - the default is just less than 2GB which is a practical limit
236        on many systems
237    o Compute the non-local term using either KPP vertical diffusivity (=default)
238       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
239    
240    checkpoint55h_post
241    o add verification test "vermix"
242    o remove all the *_ioinc flags and replace with the single global
243      outputTypesInclusive flag
244    o allow to set a vertical profile of vertical diffusivity for T & S
245    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
246    o useMNC moved from data.mnc to data.pkg
247    
248    checkpoint55g_post
249    o Renaming carbon AD experiments to comply with testreport conventions
250    o Updating adjoint of Held-Suarez hs94.1x64x5
251    o Fixing directives for non-ECCO forward_step, after ECCO directives
252      have been fixed to avoid recomp. of do_oceanic_phys
253      Works well for global_ocean.90x40x15,
254      but recomp. issue remains for carbon
255    o Updating adjoint output for natl_box_adjoint after
256      pkg/ecco has been modified (see taga c55d_post)
257    
258    checkpoint55f_post
259    o rename to timeave_init_fixed
260    
261    checkpoint55e_post
262    o some delicate re-shuffle of store directives to avoid one
263      extra call of do_oceanic_physics
264      affects ecco_the_main_loop.F, do_oceanic_physics.F
265      checkpoint_lev1_directives.h
266    o NB: this may break global_ocean adjoint temporarily,
267      but it is clear how to fix it. Will do later, need this now.
268    
269    checkpoint55d_post
270    o ECCO specific cost function terms (up-to-date with 1x1 runs)
271    o ecco_cost_weights is modified to 1x1 runs
272    o modifs to allow observations to be read in as
273      single file or yearly files
274    o enable to read exf forcing fields as either
275      single file or yearly files (flag useExfYearlyFields)
276    checkpoint55d_pre
277    
278    o switch between 2-level and 3-level checkpointing
279    o add ability of MNC to write local and "partial" (eg. 2D slices where
280      the full 3D field is never actually stored) arrays to NetCDF files
281      with the correct (that is, the complete multi-dimensional) set of
282      array indicies
283      - used in mom_vecinv() to write the diagFreq output
284      - tested (demonstrated) in verification/aim.5l_cs
285    o further mnc-ification
286      - add verification/lab_sea to the list with mnc setups
287      - fix undefined mnc v-names in cd_code
288      - add kpp to mnc output (both snapshot and timeave)
289    o non-hydrostatic code
290      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
291        in calc_gw.F
292      - defaults to viscAh
293      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
294        friction or Leith) in non-hydrostatic mode, as long as there is
295        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
296    o pkg/cost
297      extend simple cost functions to treat time mean quantities
298      (T,U,V) via cost_accumulate_state from cost_tile
299    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
300        be 2 times larger than the minimum size the advection scheme requires.
301        now get a perfect conservation of salt in advect_cs test-exp (updated)
302    o GGL90 (Gaspar's TKE mixed layer)
303      - add horizontal diffusion of TKE, requires exchanges in
304        do_fields_blocking_exchanges, horizontal diffusivity is zero by
305        default. In OPA there is no horizontal diffusion of TKE but the
306        mixing coefficients are computed from a horizontal average of TKE of
307        6 points or so. I think that diffusion has a little more physical
308        justification.
309      - clean up ggl90_calc in the hope of reducing memory usage (this hope
310        was in vain)
311      - mask tke-variable in ggl90_init
312    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
313    o fix biharmonic diffusion on CS-grid.
314    o more obcs stuff
315      - added obcs_external_fields_load as an alternative to the EXF-pkg option
316        for reading boundary values. This routine is called from
317        obcs_prescribe_read
318      - updated obcs_check
319      - changed sponge layer relaxation parameter units for days to seconds
320      - turned off sponge layer by default
321      - changed argument list of OBCS_CALC to myTime+deltaTclock
322      - fixed about 35 bugs in obcs_external_fields_load
323    
324    checkpoint55c_post
325    o obcs stuff
326      - new runtime flags useOBCSprescribe, useOBCSbalance
327      - re-arranged obcs_calc
328      - moved exf_getobcs to obcs_prescibe_read
329        obcs_prescibe_read is called after ORLANSKI stuff
330        and independent of it (executable can contain all).
331      - updated obcs_check
332      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
333        These may be necessary only if tangential velocities are
334        prescribed at OB, not sure, needs testing.
335    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
336      which simplifies the calls and passes the ifc check-bounds test
337    
338    checkpoint55b_post
339    o add a 2D scalar, Z location, exchange_2 routine.
340    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
341      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
342      affects advect_cs results (for the wrong reason): update output.txt
343    o use a more standard discretization for biharmonic viscosity ;
344     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
345      affects results of dome set-up: update output.txt
346    o fix gad_advection.F (CubedSphere part), back to version 1.23
347    o fix bug in mom_vi_del2uv.F (CubedSphere part).
348    
349    checkpoint55a_post
350    o merged code to
351      * prescribe/read time-dependent open boundaries
352        (works in conjunction with exf, cal)
353      * sponge layer code for open boundaries
354      * each boundary N/S/E/W now has its own CPP option
355        (healthy for the adjoint)
356    
357    checkpoint55
358    o up-to-date adjoint of previous breaks
359      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
360      - global_ocean_ebm: adjoint still needs fix (TLM ok)
361      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
362      - carbon: * remove tr1-related adjoint verification
363                * add ptracer as control variable
364    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
365      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
366    
367    checkpoint54f_post
368    o in verification/carbin/ remove experiment related to
369      ALLOW_PASSIVE_TRACER (array tr1 etc)
370      code_ad/ input_ad/ results_ad
371    
372    o add two new packages
373      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
374        + subject to optimization (memory)
375      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
376        + subject to reordering (many GOTOs in the original code)
377        + so far opps is called for every (i,j) point, and then operates in
378          the vertical; one may want to reorder the scheme in order operate in
379          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
380          fields)
381    o overhaul of IO so that we now have flags for MDSIO and/or MNC
382      - all verification tests compile and run with linux_ia32_g77
383      - defaults are compatible with current input files--nothing
384        should change if you were not previously using MNC
385      - MNC output has been added in numerous places (eg. timeave)
386        but there are still a few writes not yet do-able with MNC
387        (this is in progress)
388      - flags now allow for either/or/both use of MDSIO and MNC and
389        documentation will soon follow
390      - numerous small formatting cleanups for ProTeX
391    o add version info (via BUILD_INFO.h) to MNC and stdout
392    
393    checkpoint54e_post
394    o add two new packages
395      - pp81 (Packanowski and Philander, 1981), Richardson number and
396        stratification dependent mixing
397      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
398      - these scheme operate in a similar manner as KPP (without ghat, of
399        course), however there is only one diffusivity that is used for both
400        temperature and salinity (and passive tracers)ç
401    o add offline package
402    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
403      provided by Stephanie Dutkiewicz
404    o genmake2: add ability to search for C compilers and cleanup test output
405      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
406    
407    checkpoint54d_post
408    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
409    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
410      leading to additional shift by 5 days each year of integration
411       (i.e. leading to considerable offset over the years)
412    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
413    o start with no AB and no initial filtering (staggerTimeStep):
414      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
415    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
416      (external loading & cpl import/export stay in forward_step.F)
417    o update coupling interface to work with new staggerTimeStep
418    o change MDSIO ptracers_pickup.
419    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
420    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
421    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
422    
423    checkpoint54c_post
424    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
425      this affects (truncation error) output.txt of test-exp:
426       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
427    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
428    o change Qnet to always be the net heat flux, (+upward).
429      affects (truncation error) output of natl_box exp.: updated
430    o define the max number of passive tracers in PTRACERS_SIZE.h
431    o start to test mnc routinely in exp0
432    o add sea-ice loading (sIceLoad) as a new forcing field.
433    
434    checkpoint54b_post
435    o add testreport "-j JOBS" option for parallel builds (tested and pretty
436       impressive on Altix and Opteron systems)
437    o diagnostics can now write NetCDF files through the mnc package
438    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
439    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
440    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
441      affects (truncation error) output of lab_sea & natl_box exp.: updated
442    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
443    
444  checkpoint54a_post  checkpoint54a_post
445  o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).  o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
446  o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)  o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
