3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o mnc-ifying the seaice package
7    o introduced an alternative length scale calculation for use in the limiting
8      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
9    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
10    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
11      as well as grad(vort3).  Made it compatible with both approximate form
12      for the cubed sphere and full form of these gradients.  Added flag
13      useFullLeith to select between approximate and full form.  
14    o add "d0" in getcon.F to reduce differences between compilers/platforms
15      update output.txt of exp. fizhi-gridalt-hs
16    o change port_rand funtion to allow to set the seed.
17    o fix obscure MNC bug involving conversion between reals and integers
18      - it caused no problems with certain (eg. gcc, ifc) compilers but the
19        new version is now more standards-compliant
20    
21    checkpoint57e_post
22    o Adding eddy stress controls a la Ferreira et al.
23    checkpoint57e_pre
24    
25    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
26      update output.txt of exp. fizhi-gridalt-hs
27    o add more "Z" dimensions and associated coordinate vars to MNC
28    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
29    o parameter calendarDumps: when set, approximate months (30-31 days) and years
30      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
31      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
32      months and years.  Requires pkg/cal.
33    o diagnostics: add pickup functionality
34      - off by default for backwards compatibility
35      - current version only uses MDSIO -- MNC will be added
36    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
37    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
38    
39    checkpoint57d_post
40    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
41    o modify verification/ideal_2D_oce so that it tests the creation of mnc
42      output from the diagnostics package
43    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
44    o make genmake2 more portable by using ".$FS" instead of ".f" for more
45      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
46    o add coordinate variables to the MNC output from the diagnostics package
47    o change MNC-flags default value: true when useMNC=TRUE
48    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
49      the ability (off by default) to read the grid information using MNC
50    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
51    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
52    o do snap-shot diagnostics at the middle of the time-interval (instead of
53      at the end).
54    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
55      new test for AIM with thSIce + slab-ocean
56    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
57    o move state variable diagnostics to the beginning of the time step ;
58      (note: still needs some work specially for snap-shot diagnostics)
59      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
60    
61    checkpoint57c_post
62    o Change testing option (-ieee) to get closer agreement between g77 & ifort
63    o generate new output.txt files on faulks with g77 & the new -ieee option
64    checkpoint57c_pre
65    
66    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
67      update output.txt of exp. global_ocean.90x40x15
68    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
69      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
70    o add saltFlux(+File) forcing capability with periodicExternalForcing
71    o allow to use pkg diagnostics for GM-Redi & ThSIce output
72    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
73    o improvements for the MNC output from DIAGNOSTICS:
74      - correct handling of the unlimitied dimension
75      - all dims now have associated coordinate variables
76      - variables located at U, V, and Corner ("Z") points are now written
77        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
78        *all* data points are output
79    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
80    o added pkg/seaice/seaice_monitor.F
81    o mdsio_readfield.F can now read files visible only to master MPI process.
82    o pkg/seaice: some test code for ice-modified ocean stress
83    o exf_getffields interpolation defaults to bilinear for all scalar forcing
84      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
85      spurious negative numbers for precipitation and humidity.  Will cause
86      some small numerical differences for integrations using pkg/exf/exf_interp.F.
87    o pkg/ctrl/
88      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
89        May be enabled via doPackDiag
90      *  introduce z-scaling of
91         + gradient (doZscalePack) and
92         + control (doZscaleUnpack)
93    o pkg/mdsio/
94      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
95      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
96    
97    checkpoint57b_post
98    o simplify options in diagnostics_fill arguments (remove weird combinations)
99    o fix MNC coordinate variables so that they now contain per-face index
100      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
101      general, EXCH2 grids are only aligned to a "local" coordinate system
102    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
103    o Implement instantaneous output within pkg diagnostics:
104      setting a negative frequency in data.diagnostics produces
105     "snap-shot" output (as opposed to time-average if freq > 0)
106    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
107      NOTE: change ptracer diagnostics name: use 2 characters to work with
108            more than 9 tracers. Add also diagnostics of advect & diffus flux.
109    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
110      becomes the coordinate variable for the 'T' dimension
111    o add CF-style coordinate variables to MNC
112      - just a first cut:  numbers are meaningless on the cubesphere and
113        missing along the T axis but otherwise it works!
114    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
115    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
116    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
117      this is based directly on what the model compute, so that the content of
118      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
119    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
120    o clean up build options files for SunOS, in particular
121      - remove -traditional from xmakedepend
122      - change -xarch=v9 to -xarch=native for f77
123      - restore use of make (not gmake)
124      - add CC=gcc if using g77
125    o changes per discussion of AM, JMC, & EH3 today:
126      - move redundant "grid" variables out of "state" -- in preparation of
127        creating proper CF-style coordinate variables and in recognition
128        that any/all grid variables can be easily copied (eg. w/NCO) from
129        the grid files into any of the other NetCDF files
130      - *always* output grid variables with MDSIO (this will eventually be
131        changed)
132      - output MNC grid file if useMNC is true
133    o every instance of _END_MASTER() has been found and replaced with
134      _END_MASTER( myThid ) in order to satisfy certain picky Sun
135      preprocessors
136    o re-arrange diagnostics pkg initialisation:
137     - allow each package to extend the available diagnostics list
138     - add some checking and fix small problems (multi-threaded, ...)
139     - new S/R diagnostics_fill (replace fill_diagnostics):
140       look through the short list of active diag. (instead of the long list)
141       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
142    
143    checkpoint57a_post
144    o this set of changes restores TAMC compatibility
145      tested for global_ocean.90x40x15 adjoint on trough
146      (what a pain)
147    
148    checkpoint57a_pre
149    o some modifs in tools/build_options for sunos
150    o call ctrl_pack for ctrl at end for optimcycle=0
151    
152    checkpoint57
153    o add horizontal bi-harmonic viscosity for vertical velocity
154      - new parameter viscA4W (defaults to viscA4)
155      - affects only non-hydrostatic code
156      - to be done: no-slip lateral boundary conditions
157    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
158    o implement Implicit Vertical advection for pTracers
159    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
160      (implemented also for implicit vertical diffusion & advection)
161    o OBCS: extend application of tracer open boundary conditions
162      to a strip beyond the boundary of width Olx/Oly
163    o add call monitor to TAF set of required calls (flow directives)
164      and include in natl_box_adjoint
165    o untangle a few ifdefs related to cost, ctrl, autodiff
166      untangel a few ALLOW_ECCO_OPTIMIZATION
167    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
168      (theta2, salt2 in ecco_cost_weights)
169    
170    checkpoint56c_post
171    o OBCS as control variables
172      - update ctrl_ad_diff.list, obcs_ad_diff.list
173      - remove balance of obcs controls from default
174      - fix index bug nobcs in ctrl_init
175      - fix dummy fields filen in ctrl_pack
176      - add dummy weights for obcs
177    o lsopt: comment out fort.94 output
178    o optim:
179      - remove unnecessary header files
180      - adjusted namelists
181      - add xerbla.F to Makefile
182    o exf:
183      - multiple modifications of exf_check_range
184      - unit change in exf_init_runoff from [m/year] to [m/s]
185    o mdsio:
186      - i/o-vector change debugLevel from debLevA to debLevB
187    
188    checkpoint56b_post
189    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
190      is called from DO_THE_MODEL_IO
191      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
192      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
193      - clean up PTRACERS_WRITE_TIMEAVE a little
194    o add another verification experiment that tests both the cfc-pkg and
195      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
196      reactive tendencies treated inline with regular timestepping
197    o testreport previously did a lousy job of comparing small numbers, so
198      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
199      implemented in the little c-progam tmp_cmpnum.c which is embedded in
200      testreport.
201    o ptracers_monitor: bug fix for MPI
202    
203    checkpoint56a_post
204    o GCHEM: finish reorganizating the package
205      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
206        (introduces another 3D-array for each passive tracer, but only if
207        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
208        gchemTendency is not needed because the timestep is done separately)
209      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
210      - GCHEM is now---more or less cleanly---separate from PTRACERS
211      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
212        so clear to me how that should be done in a general way.
213    o CFC: improve formatting of output in CFC_ATMOS
214    o PTRACERS:
215      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
216        that ALL experiments with ptracers enable can be checked. This makes
217        GCHEM_MONITOR obsolete.
218      - include a runtime parameter PTRACERS_monitorFreq that defaults to
219        monitorFreq
220      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
221    o add PTRACERS (PTR0[1-5]) to testreport output
222    o exf_check_range:
223      * default changed to .TRUE.
224      * will check values for niter0 if debLevA, every timestep if debLevB
225      * STOP in exf_check_range if 'out of range'
226      * range chosen generous to allow for potential extema
227      TBD: a version with stricter range
228           permitted range would be runtime parameters
229    o GMredi:
230      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
231      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
232      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
233    o GCHEM:
234      - move call to GCHEM_FORCING_SEP, so that it is now called before
235        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
236      - introduced a useGCHEM runtime flag and applied it everywhere.
237      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
238        this flag is now only visible within GCHEM-pkg routines.
239      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
240        be replaced by a 3D array that is computed before thermodynamics; for
241        this, the tracer ID iTracer had to be included into the parameter list
242        of ptracers_forcing
243      - set up forward_step to call gchem_forcing, that will replace
244        gchem_forcing_int in ptracers_forcing
245      - cleaning up
246    o small cleaning of exch2: remove files that are also in eesupp/src
247    
248    checkpoint56
249    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
250    o mnc: cleanup "full" files--fixes out-of-memory problem
251    o ECCO-GODAE
252      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
253      * fully merged and updated from SIO code
254        windstress sign change affects
255        - exf_inscal_[u/v]stress
256        - sign of xx_tau[u/v] adjustments
257        - signs in cost_scat
258      * ctrl_get_gen: avoid update of tau[u/v] for first few days
259      * natl_box_adjoint updated and compressed
260      * 2-level checkpoint switch added
261        (tested in EXP. 1 of natl_box_adjoint)
262      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
263    o SVD
264      * first complete, non-hacked version for SVD calculations
265      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
266        performed via direct access files admtlm_vector.it????
267        (via ctrl_[un]pack)
268      * optimcycle is used for ARPACK iteration counter
269        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
270      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
271        and add linear transforms where necessary
272      * controls are initial/final SST, SSS (can be extended; need to check
273        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
274    o mdsio: filename info to both stderr, stdout
275    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
276      from sign change
277    
278    checkpoint55j_post
279    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
280      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
281    o add consistent build directories and .cvsignore files to verification
282    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
283    o make all subroutines 30 or less characters in length for certain older
284      compilers to work (a thorough search only turns up two routines in
285      pkg/ptracers)
286    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
287      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
288    
289    checkpoint55i_post
290    o change arrays for total vertical diffusivity (2.D if explicit,
291      3.D if implicit) ; each ptracer uses its own background value.
292    o added mnc/NetCDF output capability to ocn_compon_interf
293      - added bits to verification/cpl_aim+ocn so that it can run on
294        ITRDA and other clusters without the mpirun "-wd" option
295    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
296      configuration
297    o give MNC the ability to create additional files rather than
298      exceeding a specified file size limit "MNC_MAX_FILESIZE"
299      - the default is just less than 2GB which is a practical limit
300        on many systems
301    o Compute the non-local term using either KPP vertical diffusivity (=default)
302       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
303    
304    checkpoint55h_post
305    o add verification test "vermix"
306    o remove all the *_ioinc flags and replace with the single global
307      outputTypesInclusive flag
308    o allow to set a vertical profile of vertical diffusivity for T & S
309    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
310    o useMNC moved from data.mnc to data.pkg
311    
312    checkpoint55g_post
313    o Renaming carbon AD experiments to comply with testreport conventions
314    o Updating adjoint of Held-Suarez hs94.1x64x5
315    o Fixing directives for non-ECCO forward_step, after ECCO directives
316      have been fixed to avoid recomp. of do_oceanic_phys
317      Works well for global_ocean.90x40x15,
318      but recomp. issue remains for carbon
319    o Updating adjoint output for natl_box_adjoint after
320      pkg/ecco has been modified (see taga c55d_post)
321    
322    checkpoint55f_post
323    o rename to timeave_init_fixed
324    
325    checkpoint55e_post
326    o some delicate re-shuffle of store directives to avoid one
327      extra call of do_oceanic_physics
328      affects ecco_the_main_loop.F, do_oceanic_physics.F
329      checkpoint_lev1_directives.h
330    o NB: this may break global_ocean adjoint temporarily,
331      but it is clear how to fix it. Will do later, need this now.
332    
333    checkpoint55d_post
334    o ECCO specific cost function terms (up-to-date with 1x1 runs)
335    o ecco_cost_weights is modified to 1x1 runs
336    o modifs to allow observations to be read in as
337      single file or yearly files
338    o enable to read exf forcing fields as either
339      single file or yearly files (flag useExfYearlyFields)
340    checkpoint55d_pre
341    
342    o switch between 2-level and 3-level checkpointing
343    o add ability of MNC to write local and "partial" (eg. 2D slices where
344      the full 3D field is never actually stored) arrays to NetCDF files
345      with the correct (that is, the complete multi-dimensional) set of
346      array indicies
347      - used in mom_vecinv() to write the diagFreq output
348      - tested (demonstrated) in verification/aim.5l_cs
349  o further mnc-ification  o further mnc-ification
350    - add verification/lab_sea to the list with mnc setups    - add verification/lab_sea to the list with mnc setups
351    - fix undefined mnc v-names in cd_code    - fix undefined mnc v-names in cd_code
