4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o adding precip control xx_precip
8    o moved ptracer ctrl index 17 -> 32
9    o in natl_box_adjoint:
10      * updated: results_bulk/
11      * not yet updated: results/, results_seaice/
12    
13    checkpoint57m_post
14    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
15      and advect_cs (use EXCH-2 and standard cs-32 grid files).
16    o pkg/exch2: filling of face-corner halo regions is optional
17      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
18    
19    checkpoint57l_post
20     tag before updating tutorials (pre-release-2)
21    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
22       for output and interpolation of input fields onto model grid)
23    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
24       Affects results of exp. rotating_tank ; update output.txt.
25    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
26          and taking the square quantity and/or using a fraction-weight field.
27    o fix aim_diagnostics_init.F mate numbers.
28    o add mnc output capability to diagnostics/diagstat and update
29      our cvsignore files for the ACSII output generated
30    
31    checkpoint57k_post
32    o lab_sea now uses diagnostics package and provides a suite of
33      new EXF diagnostics output.
34    
35    checkpoint57j_post
36    o exf
37      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
38        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
39        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
40      * extended diagnostics output
41        - now includes all EXF variables
42        - hs, hl moved to common block
43        - separate S/R for diagnostics, called after ctrl vector is added
44        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
45        - EXFqnet contains true Qnet (i.e. includes qsw)
46      * updated verif. lab_sea, global_with_exf
47      * Rearranging hflux (exf_mapfields -> exf_getforcing)
48        to ensure that diagnostics sees a true EXFqnet
49    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
50    o diagnostics pkg: change pointers so that 1 diagnostic can be used
51      several times with different frequencies.
52    o mnc-ify the thsice package as requested by Daniel Enderton
53      - the monitor--MNC output needs work
54      - many attributes need to be added (most are currently blank)
55    o mnc-ify theaim_v23 package as requested by Daniel Enderton
56      - many attributes need to be added (most are currently blank)
57    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
58    o add Sadourny like discretization to the 4th.O vorticity advection scheme
59    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
60      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
61         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
62    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
63     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
64    
65    checkpoint57i_post
66    o Diagnostics package was changed: diagnostic allocation is now deactivated
67      by setting an empty file name in the namelist (used to be by setting 0 frequency)
68    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
69      add 1rst Order upwind vertical Shear.
70    o add a quick fix for A/B checkpointing in OFFLINE mode
71    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
72      end-run around the C/Fortran linking horror in eesup/src/timers.F
73    o added pkg/runclock: allows user to terminate run based on wall clock
74    o added non-hydrostatic scaling parameter: nh_am2
75    o pkg/my82: futile attempt to make results compiler-independent by adding
76      some "_d 0", etc. no effect.
77    o for mnc output, fill the 'T' coordinate var with myTime and create a
78      separate 'iter' variable for iteration count
79    o pkg/diagnostics:
80      add new capability: output of Global/Regional & per-level statistics ;
81      tested against monitor output (including land & thSIce) on various exp.
82    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
83    
84    checkpoint57h_done
85      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
86      data.diagnostics, data.gchem, data.ptracers) is done.
87    
88    o pkg/diagnostics: prepare for Global/Regional statistics.
89      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
90    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
91      and rename it: DIFFERENT_MULTIPLE
92    
93    checkpoint57h_post
94    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
95    o pkg/diagnostics: change output frequency, now in seconds (instead
96      of Nb of iterations). This requires to change data.diagnostics.
97    checkpoint57h_pre
98    
99    o in mnc, let the user create the output dir if both mnc_outdir_date
100      and mnc_outdir_num are false
101    o add fflags() to pkg/diagnostics which allows one to specify, on a
102      per-file basis, the file precision [default behavior is unchanged]
103    o added diagnostics to pkg/kpp, including computation of mixed layer
104      depth based on a temperature/density criterion
105    o updated verification/natl_box to test the new pkg/kpp diagnostics
106    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
107    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
108    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
109      not mnc -- this mistake was found by JMC and is now corrected
110    
111    checkpoint57g_post
112    o add Adams-Bashforth 3rd Order time stepping:
113      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
114      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
115    checkpoint57g_pre
116    
117    o make lambda[Theta,Salt]ClimRelax spatially varying
118      (default remains spatially uniform constant based on tau)
119    o added new control variables
120      * init. uVel, vVel, etanN
121      * lambda[Theta,Salt]ClimRelax
122    o separate masks used for ctrl_pack/unpack 'from write_grid' output
123      (suggested by G. Forget)
124    
125    checkpoint57f_post
126    o add parameter "baseTime" = model base time = time at iteration zero
127      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
128      account for baseTime shift
129    o move Coriolis arrays from PARAMS.h to GRID.h
130    checkpoint57f_pre
131    
132    o mnc-ifying the seaice package
133    o introduced an alternative length scale calculation for use in the limiting
134      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
135    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
136    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
137      as well as grad(vort3).  Made it compatible with both approximate form
138      for the cubed sphere and full form of these gradients.  Added flag
139      useFullLeith to select between approximate and full form.  
140    o add "d0" in getcon.F to reduce differences between compilers/platforms
141      update output.txt of exp. fizhi-gridalt-hs
142    o change port_rand funtion to allow to set the seed.
143    o fix obscure MNC bug involving conversion between reals and integers
144      - it caused no problems with certain (eg. gcc, ifc) compilers but the
145        new version is now more standards-compliant
146    o adjoint-related modifications
147      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
148      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
149      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
150    
151    checkpoint57e_post
152    o Adding eddy stress controls a la Ferreira et al.
153    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
154    
155    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
156      update output.txt of exp. fizhi-gridalt-hs
157    o add more "Z" dimensions and associated coordinate vars to MNC
158    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
159    o parameter calendarDumps: when set, approximate months (30-31 days) and years
160      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
161      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
162      months and years.  Requires pkg/cal.
163    o diagnostics: add pickup functionality
164      - off by default for backwards compatibility
165      - current version only uses MDSIO -- MNC will be added
166    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
167    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
168    
169    checkpoint57d_post
170    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
171    o modify verification/ideal_2D_oce so that it tests the creation of mnc
172      output from the diagnostics package
173    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
174    o make genmake2 more portable by using ".$FS" instead of ".f" for more
175      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
176    o add coordinate variables to the MNC output from the diagnostics package
177    o change MNC-flags default value: true when useMNC=TRUE
178    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
179      the ability (off by default) to read the grid information using MNC
180    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
181    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
182    o do snap-shot diagnostics at the middle of the time-interval (instead of
183      at the end).
184    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
185      new test for AIM with thSIce + slab-ocean
186    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
187    o move state variable diagnostics to the beginning of the time step ;
188      (note: still needs some work specially for snap-shot diagnostics)
189      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
190    
191    checkpoint57c_post
192    o Change testing option (-ieee) to get closer agreement between g77 & ifort
193    o generate new output.txt files on faulks with g77 & the new -ieee option
194    checkpoint57c_pre
195    
196    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
197      update output.txt of exp. global_ocean.90x40x15
198    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
199      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
200    o add saltFlux(+File) forcing capability with periodicExternalForcing
201    o allow to use pkg diagnostics for GM-Redi & ThSIce output
202    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
203    o improvements for the MNC output from DIAGNOSTICS:
204      - correct handling of the unlimitied dimension
205      - all dims now have associated coordinate variables
206      - variables located at U, V, and Corner ("Z") points are now written
207        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
208        *all* data points are output
209    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
210    o added pkg/seaice/seaice_monitor.F
211    o mdsio_readfield.F can now read files visible only to master MPI process.
212    o pkg/seaice: some test code for ice-modified ocean stress
213    o exf_getffields interpolation defaults to bilinear for all scalar forcing
214      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
215      spurious negative numbers for precipitation and humidity.  Will cause
216      some small numerical differences for integrations using pkg/exf/exf_interp.F.
217    o pkg/ctrl/
218      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
219        May be enabled via doPackDiag
220      *  introduce z-scaling of
221         + gradient (doZscalePack) and
222         + control (doZscaleUnpack)
223    o pkg/mdsio/
224      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
225      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
226    
227    checkpoint57b_post
228    o simplify options in diagnostics_fill arguments (remove weird combinations)
229    o fix MNC coordinate variables so that they now contain per-face index
230      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
231      general, EXCH2 grids are only aligned to a "local" coordinate system
232    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
233    o Implement instantaneous output within pkg diagnostics:
234      setting a negative frequency in data.diagnostics produces
235     "snap-shot" output (as opposed to time-average if freq > 0)
236    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
237      NOTE: change ptracer diagnostics name: use 2 characters to work with
238            more than 9 tracers. Add also diagnostics of advect & diffus flux.
239    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
240      becomes the coordinate variable for the 'T' dimension
241    o add CF-style coordinate variables to MNC
242      - just a first cut:  numbers are meaningless on the cubesphere and
243        missing along the T axis but otherwise it works!
244    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
245    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
246    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
247      this is based directly on what the model compute, so that the content of
248      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
249    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
250    o clean up build options files for SunOS, in particular
251      - remove -traditional from xmakedepend
252      - change -xarch=v9 to -xarch=native for f77
253      - restore use of make (not gmake)
254      - add CC=gcc if using g77
255    o changes per discussion of AM, JMC, & EH3 today:
256      - move redundant "grid" variables out of "state" -- in preparation of
257        creating proper CF-style coordinate variables and in recognition
258        that any/all grid variables can be easily copied (eg. w/NCO) from
259        the grid files into any of the other NetCDF files
260      - *always* output grid variables with MDSIO (this will eventually be
261        changed)
262      - output MNC grid file if useMNC is true
263    o every instance of _END_MASTER() has been found and replaced with
264      _END_MASTER( myThid ) in order to satisfy certain picky Sun
265      preprocessors
266    o re-arrange diagnostics pkg initialisation:
267     - allow each package to extend the available diagnostics list
268     - add some checking and fix small problems (multi-threaded, ...)
269     - new S/R diagnostics_fill (replace fill_diagnostics):
270       look through the short list of active diag. (instead of the long list)
271       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
272    
273    checkpoint57a_post
274    o this set of changes restores TAMC compatibility
275      tested for global_ocean.90x40x15 adjoint on trough
276      (what a pain)
277    
278    checkpoint57a_pre
279    o some modifs in tools/build_options for sunos
280    o call ctrl_pack for ctrl at end for optimcycle=0
281    
282    checkpoint57
283    o add horizontal bi-harmonic viscosity for vertical velocity
284      - new parameter viscA4W (defaults to viscA4)
285      - affects only non-hydrostatic code
286      - to be done: no-slip lateral boundary conditions
287    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
288    o implement Implicit Vertical advection for pTracers
289    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
290      (implemented also for implicit vertical diffusion & advection)
291    o OBCS: extend application of tracer open boundary conditions
292      to a strip beyond the boundary of width Olx/Oly
293    o add call monitor to TAF set of required calls (flow directives)
294      and include in natl_box_adjoint
295    o untangle a few ifdefs related to cost, ctrl, autodiff
296      untangel a few ALLOW_ECCO_OPTIMIZATION
297    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
298      (theta2, salt2 in ecco_cost_weights)
299    
300    checkpoint56c_post
301    o OBCS as control variables
302      - update ctrl_ad_diff.list, obcs_ad_diff.list
303      - remove balance of obcs controls from default
304      - fix index bug nobcs in ctrl_init
305      - fix dummy fields filen in ctrl_pack
306      - add dummy weights for obcs
307    o lsopt: comment out fort.94 output
308    o optim:
309      - remove unnecessary header files
310      - adjusted namelists
311      - add xerbla.F to Makefile
312    o exf:
313      - multiple modifications of exf_check_range
314      - unit change in exf_init_runoff from [m/year] to [m/s]
315    o mdsio:
316      - i/o-vector change debugLevel from debLevA to debLevB
317    
318    checkpoint56b_post
319    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
320      is called from DO_THE_MODEL_IO
321      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
322      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
323      - clean up PTRACERS_WRITE_TIMEAVE a little
324    o add another verification experiment that tests both the cfc-pkg and
325      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
326      reactive tendencies treated inline with regular timestepping
327    o testreport previously did a lousy job of comparing small numbers, so
328      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
329      implemented in the little c-progam tmp_cmpnum.c which is embedded in
330      testreport.
331    o ptracers_monitor: bug fix for MPI
332    
333    checkpoint56a_post
334    o GCHEM: finish reorganizating the package
335      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
336        (introduces another 3D-array for each passive tracer, but only if
337        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
338        gchemTendency is not needed because the timestep is done separately)
339      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
340      - GCHEM is now---more or less cleanly---separate from PTRACERS
341      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
342        so clear to me how that should be done in a general way.
343    o CFC: improve formatting of output in CFC_ATMOS
344    o PTRACERS:
345      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
346        that ALL experiments with ptracers enable can be checked. This makes
347        GCHEM_MONITOR obsolete.
348      - include a runtime parameter PTRACERS_monitorFreq that defaults to
349        monitorFreq
350      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
351    o add PTRACERS (PTR0[1-5]) to testreport output
352    o exf_check_range:
353      * default changed to .TRUE.
354      * will check values for niter0 if debLevA, every timestep if debLevB
355      * STOP in exf_check_range if 'out of range'
356      * range chosen generous to allow for potential extema
357      TBD: a version with stricter range
358           permitted range would be runtime parameters
359    o GMredi:
360      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
361      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
362      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
363    o GCHEM:
364      - move call to GCHEM_FORCING_SEP, so that it is now called before
365        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
366      - introduced a useGCHEM runtime flag and applied it everywhere.
367      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
368        this flag is now only visible within GCHEM-pkg routines.
369      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
370        be replaced by a 3D array that is computed before thermodynamics; for
371        this, the tracer ID iTracer had to be included into the parameter list
372        of ptracers_forcing
373      - set up forward_step to call gchem_forcing, that will replace
374        gchem_forcing_int in ptracers_forcing
375      - cleaning up
376    o small cleaning of exch2: remove files that are also in eesupp/src
377    
378    checkpoint56
379    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
380    o mnc: cleanup "full" files--fixes out-of-memory problem
381    o ECCO-GODAE
382      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
383      * fully merged and updated from SIO code
384        windstress sign change affects
385        - exf_inscal_[u/v]stress
386        - sign of xx_tau[u/v] adjustments
387        - signs in cost_scat
388      * ctrl_get_gen: avoid update of tau[u/v] for first few days
389      * natl_box_adjoint updated and compressed
390      * 2-level checkpoint switch added
391        (tested in EXP. 1 of natl_box_adjoint)
392      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
393    o SVD
394      * first complete, non-hacked version for SVD calculations
395      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
396        performed via direct access files admtlm_vector.it????
397        (via ctrl_[un]pack)
398      * optimcycle is used for ARPACK iteration counter
399        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
400      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
401        and add linear transforms where necessary
402      * controls are initial/final SST, SSS (can be extended; need to check
403        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
404    o mdsio: filename info to both stderr, stdout
405    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
406      from sign change
407    
408    checkpoint55j_post
409    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
410      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
411    o add consistent build directories and .cvsignore files to verification
412    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
413    o make all subroutines 30 or less characters in length for certain older
414      compilers to work (a thorough search only turns up two routines in
415      pkg/ptracers)
416    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
417      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
418    
419    checkpoint55i_post
420    o change arrays for total vertical diffusivity (2.D if explicit,
421      3.D if implicit) ; each ptracer uses its own background value.
422    o added mnc/NetCDF output capability to ocn_compon_interf
423      - added bits to verification/cpl_aim+ocn so that it can run on
424        ITRDA and other clusters without the mpirun "-wd" option
425    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
426      configuration
427    o give MNC the ability to create additional files rather than
428      exceeding a specified file size limit "MNC_MAX_FILESIZE"
429      - the default is just less than 2GB which is a practical limit
430        on many systems
431  o Compute the non-local term using either KPP vertical diffusivity (=default)  o Compute the non-local term using either KPP vertical diffusivity (=default)
432     or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)     or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
