3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint57b_post
7    o simplify options in diagnostics_fill arguments (remove weird combinations)
8    o fix MNC coordinate variables so that they now contain per-face index
9      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
10      general, EXCH2 grids are only aligned to a "local" coordinate system
11    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
12    o Implement instantaneous output within pkg diagnostics:
13      setting a negative frequency in data.diagnostics produces
14     "snap-shot" output (as opposed to time-average if freq > 0)
15    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
16      NOTE: change ptracer diagnostics name: use 2 characters to work with
17            more than 9 tracers. Add also diagnostics of advect & diffus flux.
18    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
19      becomes the coordinate variable for the 'T' dimension
20    o add CF-style coordinate variables to MNC
21      - just a first cut:  numbers are meaningless on the cubesphere and
22        missing along the T axis but otherwise it works!
23    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
24    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
25    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
26      this is based directly on what the model compute, so that the content of
27      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
28    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
29    o clean up build options files for SunOS, in particular
30      - remove -traditional from xmakedepend
31      - change -xarch=v9 to -xarch=native for f77
32      - restore use of make (not gmake)
33      - add CC=gcc if using g77
34    o changes per discussion of AM, JMC, & EH3 today:
35      - move redundant "grid" variables out of "state" -- in preparation of
36        creating proper CF-style coordinate variables and in recognition
37        that any/all grid variables can be easily copied (eg. w/NCO) from
38        the grid files into any of the other NetCDF files
39      - *always* output grid variables with MDSIO (this will eventually be
40        changed)
41      - output MNC grid file if useMNC is true
42    o every instance of _END_MASTER() has been found and replaced with
43      _END_MASTER( myThid ) in order to satisfy certain picky Sun
44      preprocessors
45    o re-arrange diagnostics pkg initialisation:
46     - allow each package to extend the available diagnostics list
47     - add some checking and fix small problems (multi-threaded, ...)
48     - new S/R diagnostics_fill (replace fill_diagnostics):
49       look through the short list of active diag. (instead of the long list)
50       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
51    
52    checkpoint57a_post
53    o this set of changes restores TAMC compatibility
54      tested for global_ocean.90x40x15 adjoint on trough
55      (what a pain)
56    
57    checkpoint57a_pre
58    o some modifs in tools/build_options for sunos
59    o call ctrl_pack for ctrl at end for optimcycle=0
60    
61    checkpoint57
62    o add horizontal bi-harmonic viscosity for vertical velocity
63      - new parameter viscA4W (defaults to viscA4)
64      - affects only non-hydrostatic code
65      - to be done: no-slip lateral boundary conditions
66    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
67    o implement Implicit Vertical advection for pTracers
68    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
69      (implemented also for implicit vertical diffusion & advection)
70    o OBCS: extend application of tracer open boundary conditions
71      to a strip beyond the boundary of width Olx/Oly
72    o add call monitor to TAF set of required calls (flow directives)
73      and include in natl_box_adjoint
74    o untangle a few ifdefs related to cost, ctrl, autodiff
75      untangel a few ALLOW_ECCO_OPTIMIZATION
76    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
77      (theta2, salt2 in ecco_cost_weights)
78    
79    checkpoint56c_post
80    o OBCS as control variables
81      - update ctrl_ad_diff.list, obcs_ad_diff.list
82      - remove balance of obcs controls from default
83      - fix index bug nobcs in ctrl_init
84      - fix dummy fields filen in ctrl_pack
85      - add dummy weights for obcs
86    o lsopt: comment out fort.94 output
87    o optim:
88      - remove unnecessary header files
89      - adjusted namelists
90      - add xerbla.F to Makefile
91    o exf:
92      - multiple modifications of exf_check_range
93      - unit change in exf_init_runoff from [m/year] to [m/s]
94    o mdsio:
95      - i/o-vector change debugLevel from debLevA to debLevB
96    
97    checkpoint56b_post
98    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
99      is called from DO_THE_MODEL_IO
100      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
101      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
102      - clean up PTRACERS_WRITE_TIMEAVE a little
103    o add another verification experiment that tests both the cfc-pkg and
104      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
105      reactive tendencies treated inline with regular timestepping
106    o testreport previously did a lousy job of comparing small numbers, so
107      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
108      implemented in the little c-progam tmp_cmpnum.c which is embedded in
109      testreport.
110    o ptracers_monitor: bug fix for MPI
111    
112    checkpoint56a_post
113    o GCHEM: finish reorganizating the package
114      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
115        (introduces another 3D-array for each passive tracer, but only if
116        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
117        gchemTendency is not needed because the timestep is done separately)
118      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
119      - GCHEM is now---more or less cleanly---separate from PTRACERS
120      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
121        so clear to me how that should be done in a general way.
122    o CFC: improve formatting of output in CFC_ATMOS
123    o PTRACERS:
124      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
125        that ALL experiments with ptracers enable can be checked. This makes
126        GCHEM_MONITOR obsolete.
127      - include a runtime parameter PTRACERS_monitorFreq that defaults to
128        monitorFreq
129      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
130    o add PTRACERS (PTR0[1-5]) to testreport output
131    o exf_check_range:
132      * default changed to .TRUE.
133      * will check values for niter0 if debLevA, every timestep if debLevB
134      * STOP in exf_check_range if 'out of range'
135      * range chosen generous to allow for potential extema
136      TBD: a version with stricter range
137           permitted range would be runtime parameters
138    o GMredi:
139      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
140      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
141      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
142    o GCHEM:
143      - move call to GCHEM_FORCING_SEP, so that it is now called before
144        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
145      - introduced a useGCHEM runtime flag and applied it everywhere.
146      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
147        this flag is now only visible within GCHEM-pkg routines.
148      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
149        be replaced by a 3D array that is computed before thermodynamics; for
150        this, the tracer ID iTracer had to be included into the parameter list
151        of ptracers_forcing
152      - set up forward_step to call gchem_forcing, that will replace
153        gchem_forcing_int in ptracers_forcing
154      - cleaning up
155    o small cleaning of exch2: remove files that are also in eesupp/src
156    
157    checkpoint56
158    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
159    o mnc: cleanup "full" files--fixes out-of-memory problem
160    o ECCO-GODAE
161      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
162      * fully merged and updated from SIO code
163        windstress sign change affects
164        - exf_inscal_[u/v]stress
165        - sign of xx_tau[u/v] adjustments
166        - signs in cost_scat
167      * ctrl_get_gen: avoid update of tau[u/v] for first few days
168      * natl_box_adjoint updated and compressed
169      * 2-level checkpoint switch added
170        (tested in EXP. 1 of natl_box_adjoint)
171      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
172    o SVD
173      * first complete, non-hacked version for SVD calculations
174      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
175        performed via direct access files admtlm_vector.it????
176        (via ctrl_[un]pack)
177      * optimcycle is used for ARPACK iteration counter
178        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
179      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
180        and add linear transforms where necessary
181      * controls are initial/final SST, SSS (can be extended; need to check
182        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
183    o mdsio: filename info to both stderr, stdout
184    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
185      from sign change
186    
187    checkpoint55j_post
188    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
189      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
190    o add consistent build directories and .cvsignore files to verification
191    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
192    o make all subroutines 30 or less characters in length for certain older
193      compilers to work (a thorough search only turns up two routines in
194      pkg/ptracers)
195    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
196      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
197    
198    checkpoint55i_post
199    o change arrays for total vertical diffusivity (2.D if explicit,
200      3.D if implicit) ; each ptracer uses its own background value.
201    o added mnc/NetCDF output capability to ocn_compon_interf
202      - added bits to verification/cpl_aim+ocn so that it can run on
203        ITRDA and other clusters without the mpirun "-wd" option
204    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
205      configuration
206    o give MNC the ability to create additional files rather than
207      exceeding a specified file size limit "MNC_MAX_FILESIZE"
208      - the default is just less than 2GB which is a practical limit
209        on many systems
210    o Compute the non-local term using either KPP vertical diffusivity (=default)
211       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
212    
213    checkpoint55h_post
214    o add verification test "vermix"
215    o remove all the *_ioinc flags and replace with the single global
216      outputTypesInclusive flag
217    o allow to set a vertical profile of vertical diffusivity for T & S
218    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
219    o useMNC moved from data.mnc to data.pkg
220    
221    checkpoint55g_post
222    o Renaming carbon AD experiments to comply with testreport conventions
223    o Updating adjoint of Held-Suarez hs94.1x64x5
224    o Fixing directives for non-ECCO forward_step, after ECCO directives
225      have been fixed to avoid recomp. of do_oceanic_phys
226      Works well for global_ocean.90x40x15,
227      but recomp. issue remains for carbon
228    o Updating adjoint output for natl_box_adjoint after
229      pkg/ecco has been modified (see taga c55d_post)
230    
231    checkpoint55f_post
232    o rename to timeave_init_fixed
233    
234    checkpoint55e_post
235    o some delicate re-shuffle of store directives to avoid one
236      extra call of do_oceanic_physics
237      affects ecco_the_main_loop.F, do_oceanic_physics.F
238      checkpoint_lev1_directives.h
239    o NB: this may break global_ocean adjoint temporarily,
240      but it is clear how to fix it. Will do later, need this now.
241    
242    checkpoint55d_post
243    o ECCO specific cost function terms (up-to-date with 1x1 runs)
244    o ecco_cost_weights is modified to 1x1 runs
245    o modifs to allow observations to be read in as
246      single file or yearly files
247    o enable to read exf forcing fields as either
248      single file or yearly files (flag useExfYearlyFields)
249    checkpoint55d_pre
250    
251    o switch between 2-level and 3-level checkpointing
252    o add ability of MNC to write local and "partial" (eg. 2D slices where
253      the full 3D field is never actually stored) arrays to NetCDF files
254      with the correct (that is, the complete multi-dimensional) set of
255      array indicies
256      - used in mom_vecinv() to write the diagFreq output
257      - tested (demonstrated) in verification/aim.5l_cs
258    o further mnc-ification
259      - add verification/lab_sea to the list with mnc setups
260      - fix undefined mnc v-names in cd_code
261      - add kpp to mnc output (both snapshot and timeave)
262    o non-hydrostatic code
263      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
264        in calc_gw.F
265      - defaults to viscAh
266      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
267        friction or Leith) in non-hydrostatic mode, as long as there is
268        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
269    o pkg/cost
270      extend simple cost functions to treat time mean quantities
271      (T,U,V) via cost_accumulate_state from cost_tile
272    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
273        be 2 times larger than the minimum size the advection scheme requires.
274        now get a perfect conservation of salt in advect_cs test-exp (updated)
275    o GGL90 (Gaspar's TKE mixed layer)
276      - add horizontal diffusion of TKE, requires exchanges in
277        do_fields_blocking_exchanges, horizontal diffusivity is zero by
278        default. In OPA there is no horizontal diffusion of TKE but the
279        mixing coefficients are computed from a horizontal average of TKE of
280        6 points or so. I think that diffusion has a little more physical
281        justification.
282      - clean up ggl90_calc in the hope of reducing memory usage (this hope
283        was in vain)
284      - mask tke-variable in ggl90_init
285    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
286    o fix biharmonic diffusion on CS-grid.
287    o more obcs stuff
288      - added obcs_external_fields_load as an alternative to the EXF-pkg option
289        for reading boundary values. This routine is called from
290        obcs_prescribe_read
291      - updated obcs_check
292      - changed sponge layer relaxation parameter units for days to seconds
293      - turned off sponge layer by default
294      - changed argument list of OBCS_CALC to myTime+deltaTclock
295      - fixed about 35 bugs in obcs_external_fields_load
296    
297    checkpoint55c_post
298    o obcs stuff
299      - new runtime flags useOBCSprescribe, useOBCSbalance
300      - re-arranged obcs_calc
301      - moved exf_getobcs to obcs_prescibe_read
302        obcs_prescibe_read is called after ORLANSKI stuff
303        and independent of it (executable can contain all).
304      - updated obcs_check
305      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
306        These may be necessary only if tangential velocities are
307        prescribed at OB, not sure, needs testing.
308    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
309      which simplifies the calls and passes the ifc check-bounds test
310    
311    checkpoint55b_post
312    o add a 2D scalar, Z location, exchange_2 routine.
313    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
314      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
315      affects advect_cs results (for the wrong reason): update output.txt
316    o use a more standard discretization for biharmonic viscosity ;
317     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
318      affects results of dome set-up: update output.txt
319    o fix gad_advection.F (CubedSphere part), back to version 1.23
320    o fix bug in mom_vi_del2uv.F (CubedSphere part).
321    
322    checkpoint55a_post
323    o merged code to
324      * prescribe/read time-dependent open boundaries
325        (works in conjunction with exf, cal)
326      * sponge layer code for open boundaries
327      * each boundary N/S/E/W now has its own CPP option
328        (healthy for the adjoint)
329    
330    checkpoint55
331    o up-to-date adjoint of previous breaks
332      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
333      - global_ocean_ebm: adjoint still needs fix (TLM ok)
334      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
335      - carbon: * remove tr1-related adjoint verification
336                * add ptracer as control variable
337    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
338      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
339    
340    checkpoint54f_post
341    o in verification/carbin/ remove experiment related to
342      ALLOW_PASSIVE_TRACER (array tr1 etc)
343      code_ad/ input_ad/ results_ad
344    
345    o add two new packages
346      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
347        + subject to optimization (memory)
348      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
349        + subject to reordering (many GOTOs in the original code)
350        + so far opps is called for every (i,j) point, and then operates in
351          the vertical; one may want to reorder the scheme in order operate in
352          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
353          fields)
354    o overhaul of IO so that we now have flags for MDSIO and/or MNC
355      - all verification tests compile and run with linux_ia32_g77
356      - defaults are compatible with current input files--nothing
357        should change if you were not previously using MNC
358      - MNC output has been added in numerous places (eg. timeave)
359        but there are still a few writes not yet do-able with MNC
360        (this is in progress)
361      - flags now allow for either/or/both use of MDSIO and MNC and
362        documentation will soon follow
363      - numerous small formatting cleanups for ProTeX
364    o add version info (via BUILD_INFO.h) to MNC and stdout
365    
366    checkpoint54e_post
367    o add two new packages
368      - pp81 (Packanowski and Philander, 1981), Richardson number and
369        stratification dependent mixing
370      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
371      - these scheme operate in a similar manner as KPP (without ghat, of
372        course), however there is only one diffusivity that is used for both
373        temperature and salinity (and passive tracers)ç
374    o add offline package
375    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
376      provided by Stephanie Dutkiewicz
377    o genmake2: add ability to search for C compilers and cleanup test output
378      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
379    
380    checkpoint54d_post
381    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
382    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
383      leading to additional shift by 5 days each year of integration
384       (i.e. leading to considerable offset over the years)
385    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
386    o start with no AB and no initial filtering (staggerTimeStep):
387      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
388    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
389      (external loading & cpl import/export stay in forward_step.F)
390    o update coupling interface to work with new staggerTimeStep
391    o change MDSIO ptracers_pickup.
392    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
393    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
394    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
395    
396    checkpoint54c_post
397    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
398      this affects (truncation error) output.txt of test-exp:
399       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
400    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
401    o change Qnet to always be the net heat flux, (+upward).
402      affects (truncation error) output of natl_box exp.: updated
403    o define the max number of passive tracers in PTRACERS_SIZE.h
404    o start to test mnc routinely in exp0
405    o add sea-ice loading (sIceLoad) as a new forcing field.
406    
407    checkpoint54b_post
408    o add testreport "-j JOBS" option for parallel builds (tested and pretty
409       impressive on Altix and Opteron systems)
410    o diagnostics can now write NetCDF files through the mnc package
411    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
412    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
413    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
414      affects (truncation error) output of lab_sea & natl_box exp.: updated
415    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
416    
417    checkpoint54a_post
418    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
419    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
420    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
421    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
422      + internal_wave (shift in writing cg2d_ini_res)
423    checkpoint54a_pre
424    
425    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
426      - modified verification/lab_sea and natl_box_adjoint accordingly
427    
428    checkpoint54
429    checkpoint53g_post
430    o prepare splitting of thermodynamics: store convect.counter in common block
431    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
432      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
433    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
434    o new parameter "nShapS": allow to treat differently S from T (nShapT)
435    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
436    o restore adjointability
437    
438    checkpoint53f_post
439    o modifications that affect AIM experiment results (update output.txt):
440      - no advection of S at top interface Nr (pkg/generic_advdiff)
441      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
442  o AIM pkg:  o AIM pkg:
443    - include stability function into surf.Flux derivative relative to Tsurf    - include stability function into surf.Flux derivative relative to Tsurf
