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