3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o change port_rand funtion to allow to set the seed.
7    o fix obscure MNC bug involving conversion between reals and integers
8      - it caused no problems with certain (eg. gcc, ifc) compilers but the
9        new version is now more standards-compliant
10    
11    checkpoint57e_post
12    o Adding eddy stress controls a la Ferreira et al.
13    checkpoint57e_pre
14    
15    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
16      update output.txt of exp. fizhi-gridalt-hs
17    o add more "Z" dimensions and associated coordinate vars to MNC
18    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
19    o parameter calendarDumps: when set, approximate months (30-31 days) and years
20      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
21      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
22      months and years.  Requires pkg/cal.
23    o diagnostics: add pickup functionality
24      - off by default for backwards compatibility
25      - current version only uses MDSIO -- MNC will be added
26    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
27    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
28    
29    checkpoint57d_post
30    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
31    o modify verification/ideal_2D_oce so that it tests the creation of mnc
32      output from the diagnostics package
33    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
34    o make genmake2 more portable by using ".$FS" instead of ".f" for more
35      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
36    o add coordinate variables to the MNC output from the diagnostics package
37    o change MNC-flags default value: true when useMNC=TRUE
38    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
39      the ability (off by default) to read the grid information using MNC
40    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
41    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
42    o do snap-shot diagnostics at the middle of the time-interval (instead of
43      at the end).
44    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
45      new test for AIM with thSIce + slab-ocean
46    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
47    o move state variable diagnostics to the beginning of the time step ;
48      (note: still needs some work specially for snap-shot diagnostics)
49      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
50    
51    checkpoint57c_post
52    o Change testing option (-ieee) to get closer agreement between g77 & ifort
53    o generate new output.txt files on faulks with g77 & the new -ieee option
54    checkpoint57c_pre
55    
56    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
57      update output.txt of exp. global_ocean.90x40x15
58    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
59      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
60    o add saltFlux(+File) forcing capability with periodicExternalForcing
61    o allow to use pkg diagnostics for GM-Redi & ThSIce output
62    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
63    o improvements for the MNC output from DIAGNOSTICS:
64      - correct handling of the unlimitied dimension
65      - all dims now have associated coordinate variables
66      - variables located at U, V, and Corner ("Z") points are now written
67        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
68        *all* data points are output
69    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
70    o added pkg/seaice/seaice_monitor.F
71    o mdsio_readfield.F can now read files visible only to master MPI process.
72    o pkg/seaice: some test code for ice-modified ocean stress
73    o exf_getffields interpolation defaults to bilinear for all scalar forcing
74      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
75      spurious negative numbers for precipitation and humidity.  Will cause
76      some small numerical differences for integrations using pkg/exf/exf_interp.F.
77    o pkg/ctrl/
78      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
79        May be enabled via doPackDiag
80      *  introduce z-scaling of
81         + gradient (doZscalePack) and
82         + control (doZscaleUnpack)
83    o pkg/mdsio/
84      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
85      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
86    
87    checkpoint57b_post
88    o simplify options in diagnostics_fill arguments (remove weird combinations)
89    o fix MNC coordinate variables so that they now contain per-face index
90      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
91      general, EXCH2 grids are only aligned to a "local" coordinate system
92    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
93    o Implement instantaneous output within pkg diagnostics:
94      setting a negative frequency in data.diagnostics produces
95     "snap-shot" output (as opposed to time-average if freq > 0)
96    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
97      NOTE: change ptracer diagnostics name: use 2 characters to work with
98            more than 9 tracers. Add also diagnostics of advect & diffus flux.
99    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
100      becomes the coordinate variable for the 'T' dimension
101    o add CF-style coordinate variables to MNC
102      - just a first cut:  numbers are meaningless on the cubesphere and
103        missing along the T axis but otherwise it works!
104    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
105    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
106    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
107      this is based directly on what the model compute, so that the content of
108      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
109    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
110    o clean up build options files for SunOS, in particular
111      - remove -traditional from xmakedepend
112      - change -xarch=v9 to -xarch=native for f77
113      - restore use of make (not gmake)
114      - add CC=gcc if using g77
115    o changes per discussion of AM, JMC, & EH3 today:
116      - move redundant "grid" variables out of "state" -- in preparation of
117        creating proper CF-style coordinate variables and in recognition
118        that any/all grid variables can be easily copied (eg. w/NCO) from
119        the grid files into any of the other NetCDF files
120      - *always* output grid variables with MDSIO (this will eventually be
121        changed)
122      - output MNC grid file if useMNC is true
123    o every instance of _END_MASTER() has been found and replaced with
124      _END_MASTER( myThid ) in order to satisfy certain picky Sun
125      preprocessors
126    o re-arrange diagnostics pkg initialisation:
127     - allow each package to extend the available diagnostics list
128     - add some checking and fix small problems (multi-threaded, ...)
129     - new S/R diagnostics_fill (replace fill_diagnostics):
130       look through the short list of active diag. (instead of the long list)
131       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
132    
133    checkpoint57a_post
134    o this set of changes restores TAMC compatibility
135      tested for global_ocean.90x40x15 adjoint on trough
136      (what a pain)
137    
138    checkpoint57a_pre
139    o some modifs in tools/build_options for sunos
140    o call ctrl_pack for ctrl at end for optimcycle=0
141    
142    checkpoint57
143    o add horizontal bi-harmonic viscosity for vertical velocity
144      - new parameter viscA4W (defaults to viscA4)
145      - affects only non-hydrostatic code
146      - to be done: no-slip lateral boundary conditions
147    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
148    o implement Implicit Vertical advection for pTracers
149    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
150      (implemented also for implicit vertical diffusion & advection)
151    o OBCS: extend application of tracer open boundary conditions
152      to a strip beyond the boundary of width Olx/Oly
153    o add call monitor to TAF set of required calls (flow directives)
154      and include in natl_box_adjoint
155    o untangle a few ifdefs related to cost, ctrl, autodiff
156      untangel a few ALLOW_ECCO_OPTIMIZATION
157    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
158      (theta2, salt2 in ecco_cost_weights)
159    
160    checkpoint56c_post
161    o OBCS as control variables
162      - update ctrl_ad_diff.list, obcs_ad_diff.list
163      - remove balance of obcs controls from default
164      - fix index bug nobcs in ctrl_init
165      - fix dummy fields filen in ctrl_pack
166      - add dummy weights for obcs
167    o lsopt: comment out fort.94 output
168    o optim:
169      - remove unnecessary header files
170      - adjusted namelists
171      - add xerbla.F to Makefile
172    o exf:
173      - multiple modifications of exf_check_range
174      - unit change in exf_init_runoff from [m/year] to [m/s]
175    o mdsio:
176      - i/o-vector change debugLevel from debLevA to debLevB
177    
178    checkpoint56b_post
179    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
180      is called from DO_THE_MODEL_IO
181      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
182      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
183      - clean up PTRACERS_WRITE_TIMEAVE a little
184    o add another verification experiment that tests both the cfc-pkg and
185      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
186      reactive tendencies treated inline with regular timestepping
187    o testreport previously did a lousy job of comparing small numbers, so
188      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
189      implemented in the little c-progam tmp_cmpnum.c which is embedded in
190      testreport.
191    o ptracers_monitor: bug fix for MPI
192    
193    checkpoint56a_post
194    o GCHEM: finish reorganizating the package
195      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
196        (introduces another 3D-array for each passive tracer, but only if
197        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
198        gchemTendency is not needed because the timestep is done separately)
199      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
200      - GCHEM is now---more or less cleanly---separate from PTRACERS
201      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
202        so clear to me how that should be done in a general way.
203    o CFC: improve formatting of output in CFC_ATMOS
204    o PTRACERS:
205      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
206        that ALL experiments with ptracers enable can be checked. This makes
207        GCHEM_MONITOR obsolete.
208      - include a runtime parameter PTRACERS_monitorFreq that defaults to
209        monitorFreq
210      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
211    o add PTRACERS (PTR0[1-5]) to testreport output
212    o exf_check_range:
213      * default changed to .TRUE.
214      * will check values for niter0 if debLevA, every timestep if debLevB
215      * STOP in exf_check_range if 'out of range'
216      * range chosen generous to allow for potential extema
217      TBD: a version with stricter range
218           permitted range would be runtime parameters
219    o GMredi:
220      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
221      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
222      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
223    o GCHEM:
224      - move call to GCHEM_FORCING_SEP, so that it is now called before
225        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
226      - introduced a useGCHEM runtime flag and applied it everywhere.
227      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
228        this flag is now only visible within GCHEM-pkg routines.
229      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
230        be replaced by a 3D array that is computed before thermodynamics; for
231        this, the tracer ID iTracer had to be included into the parameter list
232        of ptracers_forcing
233      - set up forward_step to call gchem_forcing, that will replace
234        gchem_forcing_int in ptracers_forcing
235      - cleaning up
236    o small cleaning of exch2: remove files that are also in eesupp/src
237    
238    checkpoint56
239    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
240    o mnc: cleanup "full" files--fixes out-of-memory problem
241    o ECCO-GODAE
242      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
243      * fully merged and updated from SIO code
244        windstress sign change affects
245        - exf_inscal_[u/v]stress
246        - sign of xx_tau[u/v] adjustments
247        - signs in cost_scat
248      * ctrl_get_gen: avoid update of tau[u/v] for first few days
249      * natl_box_adjoint updated and compressed
250      * 2-level checkpoint switch added
251        (tested in EXP. 1 of natl_box_adjoint)
252      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
253    o SVD
254      * first complete, non-hacked version for SVD calculations
255      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
256        performed via direct access files admtlm_vector.it????
257        (via ctrl_[un]pack)
258      * optimcycle is used for ARPACK iteration counter
259        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
260      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
261        and add linear transforms where necessary
262      * controls are initial/final SST, SSS (can be extended; need to check
263        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
264    o mdsio: filename info to both stderr, stdout
265    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
266      from sign change
267    
268    checkpoint55j_post
269    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
270      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
271    o add consistent build directories and .cvsignore files to verification
272    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
273    o make all subroutines 30 or less characters in length for certain older
274      compilers to work (a thorough search only turns up two routines in
275      pkg/ptracers)
276    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
277      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
278    
279    checkpoint55i_post
280    o change arrays for total vertical diffusivity (2.D if explicit,
281      3.D if implicit) ; each ptracer uses its own background value.
282    o added mnc/NetCDF output capability to ocn_compon_interf
283      - added bits to verification/cpl_aim+ocn so that it can run on
284        ITRDA and other clusters without the mpirun "-wd" option
285    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
286      configuration
287    o give MNC the ability to create additional files rather than
288      exceeding a specified file size limit "MNC_MAX_FILESIZE"
289      - the default is just less than 2GB which is a practical limit
290        on many systems
291    o Compute the non-local term using either KPP vertical diffusivity (=default)
292       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
293    
294    checkpoint55h_post
295    o add verification test "vermix"
296    o remove all the *_ioinc flags and replace with the single global
297      outputTypesInclusive flag
298    o allow to set a vertical profile of vertical diffusivity for T & S
299    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
300    o useMNC moved from data.mnc to data.pkg
301    
302    checkpoint55g_post
303    o Renaming carbon AD experiments to comply with testreport conventions
304    o Updating adjoint of Held-Suarez hs94.1x64x5
305    o Fixing directives for non-ECCO forward_step, after ECCO directives
306      have been fixed to avoid recomp. of do_oceanic_phys
307      Works well for global_ocean.90x40x15,
308      but recomp. issue remains for carbon
309    o Updating adjoint output for natl_box_adjoint after
310      pkg/ecco has been modified (see taga c55d_post)
311    
312    checkpoint55f_post
313    o rename to timeave_init_fixed
314    
315    checkpoint55e_post
316    o some delicate re-shuffle of store directives to avoid one
317      extra call of do_oceanic_physics
318      affects ecco_the_main_loop.F, do_oceanic_physics.F
319      checkpoint_lev1_directives.h
320    o NB: this may break global_ocean adjoint temporarily,
321      but it is clear how to fix it. Will do later, need this now.
322    
323    checkpoint55d_post
324    o ECCO specific cost function terms (up-to-date with 1x1 runs)
325    o ecco_cost_weights is modified to 1x1 runs
326    o modifs to allow observations to be read in as
327      single file or yearly files
328    o enable to read exf forcing fields as either
329      single file or yearly files (flag useExfYearlyFields)
330    checkpoint55d_pre
331    
332    o switch between 2-level and 3-level checkpointing
333    o add ability of MNC to write local and "partial" (eg. 2D slices where
334      the full 3D field is never actually stored) arrays to NetCDF files
335      with the correct (that is, the complete multi-dimensional) set of
336      array indicies
337      - used in mom_vecinv() to write the diagFreq output
338      - tested (demonstrated) in verification/aim.5l_cs
339    o further mnc-ification
340      - add verification/lab_sea to the list with mnc setups
341      - fix undefined mnc v-names in cd_code
342      - add kpp to mnc output (both snapshot and timeave)
343    o non-hydrostatic code
344      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
345        in calc_gw.F
346      - defaults to viscAh
347      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
348        friction or Leith) in non-hydrostatic mode, as long as there is
349        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
350    o pkg/cost
351      extend simple cost functions to treat time mean quantities
352      (T,U,V) via cost_accumulate_state from cost_tile
353    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
354        be 2 times larger than the minimum size the advection scheme requires.
355        now get a perfect conservation of salt in advect_cs test-exp (updated)
356    o GGL90 (Gaspar's TKE mixed layer)
357      - add horizontal diffusion of TKE, requires exchanges in
358        do_fields_blocking_exchanges, horizontal diffusivity is zero by
359        default. In OPA there is no horizontal diffusion of TKE but the
360        mixing coefficients are computed from a horizontal average of TKE of
361        6 points or so. I think that diffusion has a little more physical
362        justification.
363      - clean up ggl90_calc in the hope of reducing memory usage (this hope
364        was in vain)
365      - mask tke-variable in ggl90_init
366    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
367    o fix biharmonic diffusion on CS-grid.
368    o more obcs stuff
369      - added obcs_external_fields_load as an alternative to the EXF-pkg option
370        for reading boundary values. This routine is called from
371        obcs_prescribe_read
372      - updated obcs_check
373      - changed sponge layer relaxation parameter units for days to seconds
374      - turned off sponge layer by default
375      - changed argument list of OBCS_CALC to myTime+deltaTclock
376      - fixed about 35 bugs in obcs_external_fields_load
377    
378    checkpoint55c_post
379    o obcs stuff
380      - new runtime flags useOBCSprescribe, useOBCSbalance
381      - re-arranged obcs_calc
382      - moved exf_getobcs to obcs_prescibe_read
383        obcs_prescibe_read is called after ORLANSKI stuff
