4      ==============================      ==============================
5    
6    o modify verification/ideal_2D_oce so that it tests the creation of mnc
7      output from the diagnostics package
8    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
9    o make genmake2 more portable by using ".$FS" instead of ".f" for more
10      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
11    o add coordinate variables to the MNC output from the diagnostics package
12    o change MNC-flags default value: true when useMNC=TRUE
13    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
14      the ability (off by default) to read the grid information using MNC
15    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
16    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
17    o do snap-shot diagnostics at the middle of the time-interval (instead of
18      at the end).
19    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
20      new test for AIM with thSIce + slab-ocean
21    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
22    o move state variable diagnostics to the beginning of the time step ;
23      (note: still needs some work specially for snap-shot diagnostics)
24      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
25    
26    checkpoint57c_post
27    o Change testing option (-ieee) to get closer agreement between g77 & ifort
28    o generate new output.txt files on faulks with g77 & the new -ieee option
29    checkpoint57c_pre
30    
31    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
32      update output.txt of exp. global_ocean.90x40x15
33    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
34      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
35    o add saltFlux(+File) forcing capability with periodicExternalForcing
36    o allow to use pkg diagnostics for GM-Redi & ThSIce output
37    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
38    o improvements for the MNC output from DIAGNOSTICS:
39      - correct handling of the unlimitied dimension
40      - all dims now have associated coordinate variables
41      - variables located at U, V, and Corner ("Z") points are now written
42        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
43        *all* data points are output
44    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
45    o added pkg/seaice/seaice_monitor.F
46    o mdsio_readfield.F can now read files visible only to master MPI process.
47    o pkg/seaice: some test code for ice-modified ocean stress
48    o exf_getffields interpolation defaults to bilinear for all scalar forcing
49      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
50      spurious negative numbers for precipitation and humidity.  Will cause
51      some small numerical differences for integrations using pkg/exf/exf_interp.F.
52    o pkg/ctrl/
53      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
54        May be enabled via doPackDiag
55      *  introduce z-scaling of
56         + gradient (doZscalePack) and
57         + control (doZscaleUnpack)
58    o pkg/mdsio/
59      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
60      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
61    
62    checkpoint57b_post
63    o simplify options in diagnostics_fill arguments (remove weird combinations)
64    o fix MNC coordinate variables so that they now contain per-face index
65      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
66      general, EXCH2 grids are only aligned to a "local" coordinate system
67    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
68    o Implement instantaneous output within pkg diagnostics:
69      setting a negative frequency in data.diagnostics produces
70     "snap-shot" output (as opposed to time-average if freq > 0)
71    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
72      NOTE: change ptracer diagnostics name: use 2 characters to work with
73            more than 9 tracers. Add also diagnostics of advect & diffus flux.
74    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
75      becomes the coordinate variable for the 'T' dimension
76    o add CF-style coordinate variables to MNC
77      - just a first cut:  numbers are meaningless on the cubesphere and
78        missing along the T axis but otherwise it works!
79    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
80    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
81    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
82      this is based directly on what the model compute, so that the content of
83      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
84    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
85    o clean up build options files for SunOS, in particular
86      - remove -traditional from xmakedepend
87      - change -xarch=v9 to -xarch=native for f77
88      - restore use of make (not gmake)
89      - add CC=gcc if using g77
90    o changes per discussion of AM, JMC, & EH3 today:
91      - move redundant "grid" variables out of "state" -- in preparation of
92        creating proper CF-style coordinate variables and in recognition
93        that any/all grid variables can be easily copied (eg. w/NCO) from
94        the grid files into any of the other NetCDF files
95      - *always* output grid variables with MDSIO (this will eventually be
96        changed)
97      - output MNC grid file if useMNC is true
98    o every instance of _END_MASTER() has been found and replaced with
99      _END_MASTER( myThid ) in order to satisfy certain picky Sun
100      preprocessors
101    o re-arrange diagnostics pkg initialisation:
102     - allow each package to extend the available diagnostics list
103     - add some checking and fix small problems (multi-threaded, ...)
104     - new S/R diagnostics_fill (replace fill_diagnostics):
105       look through the short list of active diag. (instead of the long list)
106       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
107    
108    checkpoint57a_post
109    o this set of changes restores TAMC compatibility
110      tested for global_ocean.90x40x15 adjoint on trough
111      (what a pain)
112    
113    checkpoint57a_pre
114    o some modifs in tools/build_options for sunos
115    o call ctrl_pack for ctrl at end for optimcycle=0
116    
117    checkpoint57
118    o add horizontal bi-harmonic viscosity for vertical velocity
119      - new parameter viscA4W (defaults to viscA4)
120      - affects only non-hydrostatic code
121      - to be done: no-slip lateral boundary conditions
122    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
123    o implement Implicit Vertical advection for pTracers
124    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
125      (implemented also for implicit vertical diffusion & advection)
126    o OBCS: extend application of tracer open boundary conditions
127      to a strip beyond the boundary of width Olx/Oly
128    o add call monitor to TAF set of required calls (flow directives)
129      and include in natl_box_adjoint
130    o untangle a few ifdefs related to cost, ctrl, autodiff
131      untangel a few ALLOW_ECCO_OPTIMIZATION
132    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
133      (theta2, salt2 in ecco_cost_weights)
134    
135    checkpoint56c_post
136    o OBCS as control variables
137      - update ctrl_ad_diff.list, obcs_ad_diff.list
138      - remove balance of obcs controls from default
139      - fix index bug nobcs in ctrl_init
140      - fix dummy fields filen in ctrl_pack
141      - add dummy weights for obcs
142    o lsopt: comment out fort.94 output
143    o optim:
144      - remove unnecessary header files
145      - adjusted namelists
146      - add xerbla.F to Makefile
147    o exf:
148      - multiple modifications of exf_check_range
149      - unit change in exf_init_runoff from [m/year] to [m/s]
150    o mdsio:
151      - i/o-vector change debugLevel from debLevA to debLevB
152    
153    checkpoint56b_post
154    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
155      is called from DO_THE_MODEL_IO
156      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
157      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
158      - clean up PTRACERS_WRITE_TIMEAVE a little
159    o add another verification experiment that tests both the cfc-pkg and
160      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
161      reactive tendencies treated inline with regular timestepping
162    o testreport previously did a lousy job of comparing small numbers, so
163      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
164      implemented in the little c-progam tmp_cmpnum.c which is embedded in
165      testreport.
166    o ptracers_monitor: bug fix for MPI
167    
168    checkpoint56a_post
169    o GCHEM: finish reorganizating the package
170      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
171        (introduces another 3D-array for each passive tracer, but only if
172        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
173        gchemTendency is not needed because the timestep is done separately)
174      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
175      - GCHEM is now---more or less cleanly---separate from PTRACERS
176      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
177        so clear to me how that should be done in a general way.
178    o CFC: improve formatting of output in CFC_ATMOS
179    o PTRACERS:
180      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
181        that ALL experiments with ptracers enable can be checked. This makes
182        GCHEM_MONITOR obsolete.
183      - include a runtime parameter PTRACERS_monitorFreq that defaults to
184        monitorFreq
185      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
186    o add PTRACERS (PTR0[1-5]) to testreport output
187    o exf_check_range:
188      * default changed to .TRUE.
189      * will check values for niter0 if debLevA, every timestep if debLevB
190      * STOP in exf_check_range if 'out of range'
191      * range chosen generous to allow for potential extema
192      TBD: a version with stricter range
193           permitted range would be runtime parameters
194    o GMredi:
195      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
196      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
197      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
198    o GCHEM:
199      - move call to GCHEM_FORCING_SEP, so that it is now called before
200        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
201      - introduced a useGCHEM runtime flag and applied it everywhere.
202      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
203        this flag is now only visible within GCHEM-pkg routines.
204      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
205        be replaced by a 3D array that is computed before thermodynamics; for
206        this, the tracer ID iTracer had to be included into the parameter list
207        of ptracers_forcing
208      - set up forward_step to call gchem_forcing, that will replace
209        gchem_forcing_int in ptracers_forcing
210      - cleaning up
211    o small cleaning of exch2: remove files that are also in eesupp/src
212    
213    checkpoint56
214    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
215    o mnc: cleanup "full" files--fixes out-of-memory problem
216    o ECCO-GODAE
217      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
218      * fully merged and updated from SIO code
219        windstress sign change affects
220        - exf_inscal_[u/v]stress
221        - sign of xx_tau[u/v] adjustments
222        - signs in cost_scat
223      * ctrl_get_gen: avoid update of tau[u/v] for first few days
224      * natl_box_adjoint updated and compressed
225      * 2-level checkpoint switch added
226        (tested in EXP. 1 of natl_box_adjoint)
227      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
228    o SVD
229      * first complete, non-hacked version for SVD calculations
230      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
231        performed via direct access files admtlm_vector.it????
232        (via ctrl_[un]pack)
233      * optimcycle is used for ARPACK iteration counter
234        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
235      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
236        and add linear transforms where necessary
237      * controls are initial/final SST, SSS (can be extended; need to check
238        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
239    o mdsio: filename info to both stderr, stdout
240    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
241      from sign change
242    
243    checkpoint55j_post
244    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
245      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
246    o add consistent build directories and .cvsignore files to verification
247    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
248    o make all subroutines 30 or less characters in length for certain older
249      compilers to work (a thorough search only turns up two routines in
250      pkg/ptracers)
251    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
252      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
253    
254    checkpoint55i_post
255    o change arrays for total vertical diffusivity (2.D if explicit,
256      3.D if implicit) ; each ptracer uses its own background value.
257    o added mnc/NetCDF output capability to ocn_compon_interf
258      - added bits to verification/cpl_aim+ocn so that it can run on
259        ITRDA and other clusters without the mpirun "-wd" option
260    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
261      configuration
262    o give MNC the ability to create additional files rather than
263      exceeding a specified file size limit "MNC_MAX_FILESIZE"
264      - the default is just less than 2GB which is a practical limit
265        on many systems
266    o Compute the non-local term using either KPP vertical diffusivity (=default)
267       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
268    
269    checkpoint55h_post
270    o add verification test "vermix"
271    o remove all the *_ioinc flags and replace with the single global
272      outputTypesInclusive flag
273    o allow to set a vertical profile of vertical diffusivity for T & S
274    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
275    o useMNC moved from data.mnc to data.pkg
276    
277    checkpoint55g_post
278    o Renaming carbon AD experiments to comply with testreport conventions
279    o Updating adjoint of Held-Suarez hs94.1x64x5
280    o Fixing directives for non-ECCO forward_step, after ECCO directives
281      have been fixed to avoid recomp. of do_oceanic_phys
282      Works well for global_ocean.90x40x15,
283      but recomp. issue remains for carbon
284    o Updating adjoint output for natl_box_adjoint after
285      pkg/ecco has been modified (see taga c55d_post)
286    
287    checkpoint55f_post
288    o rename to timeave_init_fixed
289    
290    checkpoint55e_post
291    o some delicate re-shuffle of store directives to avoid one
292      extra call of do_oceanic_physics
293      affects ecco_the_main_loop.F, do_oceanic_physics.F
294      checkpoint_lev1_directives.h
295    o NB: this may break global_ocean adjoint temporarily,
296      but it is clear how to fix it. Will do later, need this now.
297    
298    checkpoint55d_post
299    o ECCO specific cost function terms (up-to-date with 1x1 runs)
300    o ecco_cost_weights is modified to 1x1 runs
301    o modifs to allow observations to be read in as
302      single file or yearly files
303    o enable to read exf forcing fields as either
304      single file or yearly files (flag useExfYearlyFields)
305    checkpoint55d_pre
306    
307    o switch between 2-level and 3-level checkpointing
308    o add ability of MNC to write local and "partial" (eg. 2D slices where
309      the full 3D field is never actually stored) arrays to NetCDF files
310      with the correct (that is, the complete multi-dimensional) set of
311      array indicies
312      - used in mom_vecinv() to write the diagFreq output
313      - tested (demonstrated) in verification/aim.5l_cs
314    o further mnc-ification
315      - add verification/lab_sea to the list with mnc setups
316      - fix undefined mnc v-names in cd_code
317      - add kpp to mnc output (both snapshot and timeave)
318    o non-hydrostatic code
319      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
320        in calc_gw.F
321      - defaults to viscAh
322      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
323        friction or Leith) in non-hydrostatic mode, as long as there is
324        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
325    o pkg/cost
326      extend simple cost functions to treat time mean quantities
327      (T,U,V) via cost_accumulate_state from cost_tile
328    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
329        be 2 times larger than the minimum size the advection scheme requires.
330        now get a perfect conservation of salt in advect_cs test-exp (updated)
331    o GGL90 (Gaspar's TKE mixed layer)
332      - add horizontal diffusion of TKE, requires exchanges in
333        do_fields_blocking_exchanges, horizontal diffusivity is zero by
334        default. In OPA there is no horizontal diffusion of TKE but the
335        mixing coefficients are computed from a horizontal average of TKE of
336        6 points or so. I think that diffusion has a little more physical
337        justification.
338      - clean up ggl90_calc in the hope of reducing memory usage (this hope
339        was in vain)
340      - mask tke-variable in ggl90_init
341    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
342    o fix biharmonic diffusion on CS-grid.
343    o more obcs stuff
344      - added obcs_external_fields_load as an alternative to the EXF-pkg option
345        for reading boundary values. This routine is called from
346        obcs_prescribe_read
347      - updated obcs_check
348      - changed sponge layer relaxation parameter units for days to seconds
349      - turned off sponge layer by default
350      - changed argument list of OBCS_CALC to myTime+deltaTclock
351      - fixed about 35 bugs in obcs_external_fields_load
352    
353    checkpoint55c_post
354    o obcs stuff
355      - new runtime flags useOBCSprescribe, useOBCSbalance
356      - re-arranged obcs_calc
357      - moved exf_getobcs to obcs_prescibe_read
358        obcs_prescibe_read is called after ORLANSKI stuff
359        and independent of it (executable can contain all).
360      - updated obcs_check
361      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
362        These may be necessary only if tangential velocities are
363        prescribed at OB, not sure, needs testing.
364    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
365      which simplifies the calls and passes the ifc check-bounds test
366    
367    checkpoint55b_post
368    o add a 2D scalar, Z location, exchange_2 routine.
369    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
370      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
371      affects advect_cs results (for the wrong reason): update output.txt
372  o use a more standard discretization for biharmonic viscosity ;  o use a more standard discretization for biharmonic viscosity ;
373   (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )   (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
374    affects results of dome set-up: update output.txt    affects results of dome set-up: update output.txt
