4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o added pkg/runclock: allows user to terminate run based on wall clock
8    o added non-hydrostatic scaling parameter: nh_am2
9    o pkg/my82: futile attempt to make results compiler-independent by adding
10      some "_d 0", etc. no effect.
11    o for mnc output, fill the 'T' coordinate var with myTime and create a
12      separate 'iter' variable for iteration count
13    o pkg/diagnostics:
14      add new capability: output of Global/Regional & per-level statistics ;
15      tested against monitor output (including land & thSIce) on various exp.
16    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
17    
18    checkpoint57h_done
19      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
20      data.diagnostics, data.gchem, data.ptracers) is done.
21    
22    o pkg/diagnostics: prepare for Global/Regional statistics.
23      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
24    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
25      and rename it: DIFFERENT_MULTIPLE
26    
27    checkpoint57h_post
28    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
29    o pkg/diagnostics: change output frequency, now in seconds (instead
30      of Nb of iterations). This requires to change data.diagnostics.
31    checkpoint57h_pre
32    
33    o in mnc, let the user create the output dir if both mnc_outdir_date
34      and mnc_outdir_num are false
35    o add fflags() to pkg/diagnostics which allows one to specify, on a
36      per-file basis, the file precision [default behavior is unchanged]
37    o added diagnostics to pkg/kpp, including computation of mixed layer
38      depth based on a temperature/density criterion
39    o updated verification/natl_box to test the new pkg/kpp diagnostics
40    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
41    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
42    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
43      not mnc -- this mistake was found by JMC and is now corrected
44    
45    checkpoint57g_post
46    o add Adams-Bashforth 3rd Order time stepping:
47      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
48      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
49    checkpoint57g_pre
50    
51    o make lambda[Theta,Salt]ClimRelax spatially varying
52      (default remains spatially uniform constant based on tau)
53    o added new control variables
54      * init. uVel, vVel, etanN
55      * lambda[Theta,Salt]ClimRelax
56    o separate masks used for ctrl_pack/unpack 'from write_grid' output
57      (suggested by G. Forget)
58    
59    checkpoint57f_post
60    o add parameter "baseTime" = model base time = time at iteration zero
61      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
62      account for baseTime shift
63    o move Coriolis arrays from PARAMS.h to GRID.h
64    checkpoint57f_pre
65    
66    o mnc-ifying the seaice package
67    o introduced an alternative length scale calculation for use in the limiting
68      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
69    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
70    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
71      as well as grad(vort3).  Made it compatible with both approximate form
72      for the cubed sphere and full form of these gradients.  Added flag
73      useFullLeith to select between approximate and full form.  
74    o add "d0" in getcon.F to reduce differences between compilers/platforms
75      update output.txt of exp. fizhi-gridalt-hs
76    o change port_rand funtion to allow to set the seed.
77    o fix obscure MNC bug involving conversion between reals and integers
78      - it caused no problems with certain (eg. gcc, ifc) compilers but the
79        new version is now more standards-compliant
80    o adjoint-related modifications
81      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
82      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
83      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
84    
85    checkpoint57e_post
86    o Adding eddy stress controls a la Ferreira et al.
87    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
88    
89    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
90      update output.txt of exp. fizhi-gridalt-hs
91    o add more "Z" dimensions and associated coordinate vars to MNC
92    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
93    o parameter calendarDumps: when set, approximate months (30-31 days) and years
94      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
95      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
96      months and years.  Requires pkg/cal.
97    o diagnostics: add pickup functionality
98      - off by default for backwards compatibility
99      - current version only uses MDSIO -- MNC will be added
100    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
101    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
102    
103    checkpoint57d_post
104    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
105    o modify verification/ideal_2D_oce so that it tests the creation of mnc
106      output from the diagnostics package
107    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
108    o make genmake2 more portable by using ".$FS" instead of ".f" for more
109      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
110    o add coordinate variables to the MNC output from the diagnostics package
111    o change MNC-flags default value: true when useMNC=TRUE
112    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
113      the ability (off by default) to read the grid information using MNC
114    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
115    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
116    o do snap-shot diagnostics at the middle of the time-interval (instead of
117      at the end).
118    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
119      new test for AIM with thSIce + slab-ocean
120    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
121    o move state variable diagnostics to the beginning of the time step ;
122      (note: still needs some work specially for snap-shot diagnostics)
123      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
124    
125    checkpoint57c_post
126    o Change testing option (-ieee) to get closer agreement between g77 & ifort
127    o generate new output.txt files on faulks with g77 & the new -ieee option
128    checkpoint57c_pre
129    
130    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
131      update output.txt of exp. global_ocean.90x40x15
132    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
133      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
134    o add saltFlux(+File) forcing capability with periodicExternalForcing
135    o allow to use pkg diagnostics for GM-Redi & ThSIce output
136    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
137    o improvements for the MNC output from DIAGNOSTICS:
138      - correct handling of the unlimitied dimension
139      - all dims now have associated coordinate variables
140      - variables located at U, V, and Corner ("Z") points are now written
141        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
142        *all* data points are output
143    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
144    o added pkg/seaice/seaice_monitor.F
145    o mdsio_readfield.F can now read files visible only to master MPI process.
146    o pkg/seaice: some test code for ice-modified ocean stress
147    o exf_getffields interpolation defaults to bilinear for all scalar forcing
148      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
149      spurious negative numbers for precipitation and humidity.  Will cause
150      some small numerical differences for integrations using pkg/exf/exf_interp.F.
151    o pkg/ctrl/
152      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
153        May be enabled via doPackDiag
154      *  introduce z-scaling of
155         + gradient (doZscalePack) and
156         + control (doZscaleUnpack)
157    o pkg/mdsio/
158      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
159      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
160    
161    checkpoint57b_post
162    o simplify options in diagnostics_fill arguments (remove weird combinations)
163    o fix MNC coordinate variables so that they now contain per-face index
164      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
165      general, EXCH2 grids are only aligned to a "local" coordinate system
166    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
167    o Implement instantaneous output within pkg diagnostics:
168      setting a negative frequency in data.diagnostics produces
169     "snap-shot" output (as opposed to time-average if freq > 0)
170    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
171      NOTE: change ptracer diagnostics name: use 2 characters to work with
172            more than 9 tracers. Add also diagnostics of advect & diffus flux.
173    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
174      becomes the coordinate variable for the 'T' dimension
175    o add CF-style coordinate variables to MNC
176      - just a first cut:  numbers are meaningless on the cubesphere and
177        missing along the T axis but otherwise it works!
178    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
179    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
180    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
181      this is based directly on what the model compute, so that the content of
182      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
183    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
184    o clean up build options files for SunOS, in particular
185      - remove -traditional from xmakedepend
186      - change -xarch=v9 to -xarch=native for f77
187      - restore use of make (not gmake)
188      - add CC=gcc if using g77
189    o changes per discussion of AM, JMC, & EH3 today:
190      - move redundant "grid" variables out of "state" -- in preparation of
191        creating proper CF-style coordinate variables and in recognition
192        that any/all grid variables can be easily copied (eg. w/NCO) from
193        the grid files into any of the other NetCDF files
194      - *always* output grid variables with MDSIO (this will eventually be
195        changed)
196      - output MNC grid file if useMNC is true
197    o every instance of _END_MASTER() has been found and replaced with
198      _END_MASTER( myThid ) in order to satisfy certain picky Sun
199      preprocessors
200    o re-arrange diagnostics pkg initialisation:
201     - allow each package to extend the available diagnostics list
202     - add some checking and fix small problems (multi-threaded, ...)
203     - new S/R diagnostics_fill (replace fill_diagnostics):
204       look through the short list of active diag. (instead of the long list)
205       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
206    
207    checkpoint57a_post
208    o this set of changes restores TAMC compatibility
209      tested for global_ocean.90x40x15 adjoint on trough
210      (what a pain)
211    
212    checkpoint57a_pre
213    o some modifs in tools/build_options for sunos
214    o call ctrl_pack for ctrl at end for optimcycle=0
215    
216    checkpoint57
217    o add horizontal bi-harmonic viscosity for vertical velocity
218      - new parameter viscA4W (defaults to viscA4)
219      - affects only non-hydrostatic code
220      - to be done: no-slip lateral boundary conditions
221    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
222    o implement Implicit Vertical advection for pTracers
223    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
224      (implemented also for implicit vertical diffusion & advection)
225    o OBCS: extend application of tracer open boundary conditions
226      to a strip beyond the boundary of width Olx/Oly
227    o add call monitor to TAF set of required calls (flow directives)
228      and include in natl_box_adjoint
229    o untangle a few ifdefs related to cost, ctrl, autodiff
230      untangel a few ALLOW_ECCO_OPTIMIZATION
231    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
232      (theta2, salt2 in ecco_cost_weights)
233    
234    checkpoint56c_post
235    o OBCS as control variables
236      - update ctrl_ad_diff.list, obcs_ad_diff.list
237      - remove balance of obcs controls from default
238      - fix index bug nobcs in ctrl_init
239      - fix dummy fields filen in ctrl_pack
240      - add dummy weights for obcs
241    o lsopt: comment out fort.94 output
242    o optim:
243      - remove unnecessary header files
244      - adjusted namelists
245      - add xerbla.F to Makefile
246    o exf:
247      - multiple modifications of exf_check_range
248      - unit change in exf_init_runoff from [m/year] to [m/s]
249    o mdsio:
250      - i/o-vector change debugLevel from debLevA to debLevB
251    
252    checkpoint56b_post
253    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
254      is called from DO_THE_MODEL_IO
255      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
256      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
257      - clean up PTRACERS_WRITE_TIMEAVE a little
258    o add another verification experiment that tests both the cfc-pkg and
259      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
260      reactive tendencies treated inline with regular timestepping
261    o testreport previously did a lousy job of comparing small numbers, so
262      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
263      implemented in the little c-progam tmp_cmpnum.c which is embedded in
264      testreport.
265    o ptracers_monitor: bug fix for MPI
266    
267    checkpoint56a_post
268    o GCHEM: finish reorganizating the package
269      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
270        (introduces another 3D-array for each passive tracer, but only if
271        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
272        gchemTendency is not needed because the timestep is done separately)
273      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
274      - GCHEM is now---more or less cleanly---separate from PTRACERS
275      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
276        so clear to me how that should be done in a general way.
277    o CFC: improve formatting of output in CFC_ATMOS
278    o PTRACERS:
279      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
280        that ALL experiments with ptracers enable can be checked. This makes
281        GCHEM_MONITOR obsolete.
282      - include a runtime parameter PTRACERS_monitorFreq that defaults to
283        monitorFreq
284      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
285    o add PTRACERS (PTR0[1-5]) to testreport output
286    o exf_check_range:
287      * default changed to .TRUE.
288      * will check values for niter0 if debLevA, every timestep if debLevB
289      * STOP in exf_check_range if 'out of range'
290      * range chosen generous to allow for potential extema
291      TBD: a version with stricter range
292           permitted range would be runtime parameters
293    o GMredi:
294      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
295      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
296      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
297    o GCHEM:
298      - move call to GCHEM_FORCING_SEP, so that it is now called before
299        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
300      - introduced a useGCHEM runtime flag and applied it everywhere.
301      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
302        this flag is now only visible within GCHEM-pkg routines.
303      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
304        be replaced by a 3D array that is computed before thermodynamics; for
305        this, the tracer ID iTracer had to be included into the parameter list
306        of ptracers_forcing
307      - set up forward_step to call gchem_forcing, that will replace
308        gchem_forcing_int in ptracers_forcing
309      - cleaning up
310    o small cleaning of exch2: remove files that are also in eesupp/src
311    
312    checkpoint56
313    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
314    o mnc: cleanup "full" files--fixes out-of-memory problem
315    o ECCO-GODAE
316      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
317      * fully merged and updated from SIO code
318        windstress sign change affects
319        - exf_inscal_[u/v]stress
320        - sign of xx_tau[u/v] adjustments
321        - signs in cost_scat
322      * ctrl_get_gen: avoid update of tau[u/v] for first few days
323      * natl_box_adjoint updated and compressed
324      * 2-level checkpoint switch added
325        (tested in EXP. 1 of natl_box_adjoint)
326      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
327    o SVD
328      * first complete, non-hacked version for SVD calculations
329      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
330        performed via direct access files admtlm_vector.it????
331        (via ctrl_[un]pack)
332      * optimcycle is used for ARPACK iteration counter
333        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
334      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
335        and add linear transforms where necessary
336      * controls are initial/final SST, SSS (can be extended; need to check
337        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
338    o mdsio: filename info to both stderr, stdout
339    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
340      from sign change
341    
342    checkpoint55j_post
343    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
344      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
345    o add consistent build directories and .cvsignore files to verification
346    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
347    o make all subroutines 30 or less characters in length for certain older
348      compilers to work (a thorough search only turns up two routines in
349      pkg/ptracers)
350    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
351      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
352    
353    checkpoint55i_post
354    o change arrays for total vertical diffusivity (2.D if explicit,
355      3.D if implicit) ; each ptracer uses its own background value.
356    o added mnc/NetCDF output capability to ocn_compon_interf
357      - added bits to verification/cpl_aim+ocn so that it can run on
358        ITRDA and other clusters without the mpirun "-wd" option
359    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
360      configuration
361    o give MNC the ability to create additional files rather than
362      exceeding a specified file size limit "MNC_MAX_FILESIZE"
363      - the default is just less than 2GB which is a practical limit
364        on many systems
365    o Compute the non-local term using either KPP vertical diffusivity (=default)
366       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
367    
368    checkpoint55h_post
369    o add verification test "vermix"
370    o remove all the *_ioinc flags and replace with the single global
371      outputTypesInclusive flag
372    o allow to set a vertical profile of vertical diffusivity for T & S
373    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
374    o useMNC moved from data.mnc to data.pkg
375    
376    checkpoint55g_post
377    o Renaming carbon AD experiments to comply with testreport conventions
378    o Updating adjoint of Held-Suarez hs94.1x64x5
379    o Fixing directives for non-ECCO forward_step, after ECCO directives
380      have been fixed to avoid recomp. of do_oceanic_phys
381      Works well for global_ocean.90x40x15,
382      but recomp. issue remains for carbon
383    o Updating adjoint output for natl_box_adjoint after
384      pkg/ecco has been modified (see taga c55d_post)
385    
386    checkpoint55f_post
387    o rename to timeave_init_fixed
388    
389    checkpoint55e_post
390    o some delicate re-shuffle of store directives to avoid one
391      extra call of do_oceanic_physics
392      affects ecco_the_main_loop.F, do_oceanic_physics.F
393      checkpoint_lev1_directives.h
394    o NB: this may break global_ocean adjoint temporarily,
395      but it is clear how to fix it. Will do later, need this now.
396    
397    checkpoint55d_post
398    o ECCO specific cost function terms (up-to-date with 1x1 runs)
399    o ecco_cost_weights is modified to 1x1 runs
400    o modifs to allow observations to be read in as
401      single file or yearly files
402    o enable to read exf forcing fields as either
403      single file or yearly files (flag useExfYearlyFields)
404    checkpoint55d_pre
405    
406    o switch between 2-level and 3-level checkpointing
407    o add ability of MNC to write local and "partial" (eg. 2D slices where
408      the full 3D field is never actually stored) arrays to NetCDF files
409      with the correct (that is, the complete multi-dimensional) set of
410      array indicies
411      - used in mom_vecinv() to write the diagFreq output
412      - tested (demonstrated) in verification/aim.5l_cs
413    o further mnc-ification
414      - add verification/lab_sea to the list with mnc setups
415      - fix undefined mnc v-names in cd_code
416      - add kpp to mnc output (both snapshot and timeave)
417    o non-hydrostatic code
418      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
419        in calc_gw.F
420      - defaults to viscAh
421      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
422        friction or Leith) in non-hydrostatic mode, as long as there is
423        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
424    o pkg/cost
425      extend simple cost functions to treat time mean quantities
426      (T,U,V) via cost_accumulate_state from cost_tile
427    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
428        be 2 times larger than the minimum size the advection scheme requires.
429        now get a perfect conservation of salt in advect_cs test-exp (updated)
430    o GGL90 (Gaspar's TKE mixed layer)
431      - add horizontal diffusion of TKE, requires exchanges in
432        do_fields_blocking_exchanges, horizontal diffusivity is zero by
433        default. In OPA there is no horizontal diffusion of TKE but the
434        mixing coefficients are computed from a horizontal average of TKE of
435        6 points or so. I think that diffusion has a little more physical
436        justification.
437      - clean up ggl90_calc in the hope of reducing memory usage (this hope
438        was in vain)
439      - mask tke-variable in ggl90_init
440    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
441    o fix biharmonic diffusion on CS-grid.
442    o more obcs stuff
443      - added obcs_external_fields_load as an alternative to the EXF-pkg option
444        for reading boundary values. This routine is called from
445        obcs_prescribe_read
446      - updated obcs_check
447      - changed sponge layer relaxation parameter units for days to seconds
448      - turned off sponge layer by default
449      - changed argument list of OBCS_CALC to myTime+deltaTclock
450      - fixed about 35 bugs in obcs_external_fields_load
451    
452    checkpoint55c_post
453    o obcs stuff
454      - new runtime flags useOBCSprescribe, useOBCSbalance
455      - re-arranged obcs_calc
456      - moved exf_getobcs to obcs_prescibe_read
457        obcs_prescibe_read is called after ORLANSKI stuff
458        and independent of it (executable can contain all).
459      - updated obcs_check
460      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
461        These may be necessary only if tangential velocities are
462        prescribed at OB, not sure, needs testing.
463    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
464      which simplifies the calls and passes the ifc check-bounds test
465    
466    checkpoint55b_post
467    o add a 2D scalar, Z location, exchange_2 routine.
468    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
469      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
470      affects advect_cs results (for the wrong reason): update output.txt
471    o use a more standard discretization for biharmonic viscosity ;
472     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
473      affects results of dome set-up: update output.txt
474    o fix gad_advection.F (CubedSphere part), back to version 1.23
475    o fix bug in mom_vi_del2uv.F (CubedSphere part).
476    
477    checkpoint55a_post
478    o merged code to
479      * prescribe/read time-dependent open boundaries
480        (works in conjunction with exf, cal)
481      * sponge layer code for open boundaries
482      * each boundary N/S/E/W now has its own CPP option
483        (healthy for the adjoint)
484    
485    checkpoint55
486    o up-to-date adjoint of previous breaks
487      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
488      - global_ocean_ebm: adjoint still needs fix (TLM ok)
489      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
490      - carbon: * remove tr1-related adjoint verification
491                * add ptracer as control variable
492    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
493      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
494    
495    checkpoint54f_post
496    o in verification/carbin/ remove experiment related to
497      ALLOW_PASSIVE_TRACER (array tr1 etc)
498      code_ad/ input_ad/ results_ad
499    
500    o add two new packages
501      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
502        + subject to optimization (memory)
503      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
504        + subject to reordering (many GOTOs in the original code)
505        + so far opps is called for every (i,j) point, and then operates in
506          the vertical; one may want to reorder the scheme in order operate in
507          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
508          fields)
509    o overhaul of IO so that we now have flags for MDSIO and/or MNC
510      - all verification tests compile and run with linux_ia32_g77
511      - defaults are compatible with current input files--nothing
512        should change if you were not previously using MNC
513      - MNC output has been added in numerous places (eg. timeave)
514        but there are still a few writes not yet do-able with MNC
515        (this is in progress)
516      - flags now allow for either/or/both use of MDSIO and MNC and
517        documentation will soon follow
518      - numerous small formatting cleanups for ProTeX
519    o add version info (via BUILD_INFO.h) to MNC and stdout
520    
521    checkpoint54e_post
522    o add two new packages
523      - pp81 (Packanowski and Philander, 1981), Richardson number and
524        stratification dependent mixing
525      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
526      - these scheme operate in a similar manner as KPP (without ghat, of
527        course), however there is only one diffusivity that is used for both
528        temperature and salinity (and passive tracers)ç
529    o add offline package
530    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
531      provided by Stephanie Dutkiewicz
532    o genmake2: add ability to search for C compilers and cleanup test output
533      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
534    
535    checkpoint54d_post
536    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
537    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
538      leading to additional shift by 5 days each year of integration
539       (i.e. leading to considerable offset over the years)
540    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
541    o start with no AB and no initial filtering (staggerTimeStep):
542      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
543    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
544      (external loading & cpl import/export stay in forward_step.F)
545    o update coupling interface to work with new staggerTimeStep
546    o change MDSIO ptracers_pickup.
547    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
548    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
549    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
550    
551    checkpoint54c_post
552    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
553      this affects (truncation error) output.txt of test-exp:
554       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
555    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
556    o change Qnet to always be the net heat flux, (+upward).
557      affects (truncation error) output of natl_box exp.: updated
558    o define the max number of passive tracers in PTRACERS_SIZE.h
559    o start to test mnc routinely in exp0
560    o add sea-ice loading (sIceLoad) as a new forcing field.
561    
562    checkpoint54b_post
563    o add testreport "-j JOBS" option for parallel builds (tested and pretty
564       impressive on Altix and Opteron systems)
565    o diagnostics can now write NetCDF files through the mnc package
566    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
567    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
568    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
569      affects (truncation error) output of lab_sea & natl_box exp.: updated
570    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
571    
572    checkpoint54a_post
573    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
574    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
575    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
576    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
577      + internal_wave (shift in writing cg2d_ini_res)
578    checkpoint54a_pre
579    
580    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
581      - modified verification/lab_sea and natl_box_adjoint accordingly
582    
583    checkpoint54
584    checkpoint53g_post
585    o prepare splitting of thermodynamics: store convect.counter in common block
586    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
587      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
588    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
589    o new parameter "nShapS": allow to treat differently S from T (nShapT)
590    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
591    o restore adjointability
592    
593    checkpoint53f_post
594    o modifications that affect AIM experiment results (update output.txt):
595      - no advection of S at top interface Nr (pkg/generic_advdiff)
596      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
597    o AIM pkg:
598      - include stability function into surf.Flux derivative relative to Tsurf
599      - calculate clear-sky radiation & surface temp. change (for diagnostics)
600    
601    checkpoint53e_post
602    o merged cylindrical coord configuration
603    o added rotating_tank experiment
604    checkpoint53e_pre
605    
606    checkpoint53d_post
607    o faulks upgraded: re-generate output.txt that have changed:
608       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
609    o Added Bryan and Lewis, 1979, vertical diffusivity profile
610    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
611    o added Sadourny discretization of Coriolis
612      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
613      - re-enabled use of omega3 (useAbsVorticity)
614    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
615      vector-invariant equations
616      - note: does *NOT* yet use same variable visc. for no-slip BC's.
617    o recoded the lateral boundary conditions for non-hydrostatic w, this time
618      hopefully without new bugs
619      - still to do: biharmonic friction for non-hydrostatic w
620    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
621    o regenerated output for global_ocean_ebm (using -ieee)
622    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
623      of mom_common/
624      - simple re-arrangement of instructions within computing loop
625    checkpoint53d_pre
626    
627    checkpoint53c_post
628    o new version of coupler for AIM+thSIce and Ocean models
629     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
630     - land: change Evaporation of snow
631     - aim with thSIce: fix bug in snow-precip.
632    o changes to calc_gw.F
633     - bug fix for w^2 term near the bottom boundary
634     - (hopefully) improve the lateral slip boundary condtions for use with
635        partial/looped cells
636      - because the bug fix changes two verification experiments anyway (exp5
637        and plume on slope), change the lateral boundary condition from half slip
638        to the value of no_slip_sides
639    o ebm package wasnt quite up to the parallel task. Fixed that.
640    o Adjoint of EBM package + verification
641      * TLM OK
642      * ADM not sufficient accuracy yet (needs further testing)
643    
644    checkpoint53b_post
645    o Commiting new energy balance model to repository
646      * package is pkg/ebm
647      * verif. is verification/global_ocean_ebm
648      * references are in ebm_driver.F
649    C      * X. Wang, P. Stone and J. Marotzke, 1999:
650    C        Global thermohaline circulation. Part I:
651    C        Sensitivity to atmospheric moisture transport.
652    C        J. Climate 12(1), 71-82
653    C      * X. Wang, P. Stone and J. Marotzke, 1999:
654    C        Global thermohaline circulation. Part II:
655    C        Sensitivity with interactive transport.
656    C        J. Climate 12(1), 83-91
657    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
658    C        Destabilization of the thermohaline circulation
659    C        by atmospheric eddy transports.
660    C        J. Climate 7(12), 1870-1882
661    o Will need long integration testing.
662    checkpoint53b_pre
663    
664    o created pkg/mom_common in preparation for variable viscosity code
665    o renamed and split ini_mnc_io
666    o pkg/land: only liquid water can diffuse or run-off
667    o AIM using land: soil wetness availability account for snow
668    o added printMapIncludesZeros to EEPARMS namelist
669    
670    checkpoint53a_post
671    o restore TAMC compatiility for exf_constants.h
672      (no usage of _d in .h)
673    o Additional storing in KPP in an attempt to fix
674      TAMC problem with adjoint of KPP code.
675      (no success...)
676      Identical code works fine with TAF.
677    o Fixed verification/natl_box_adjoint experiments.
678      Initial conditions for Experiments 4 and 5 are now
679      set to "SEAICE_initialHEFF=0", which is more reasonable,
680      and hence gives results closer to that of Experiment 2.
681      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
682    
683    checkpoint53
684    o stable checkpoint with up to date adjoint
685      TLM tests only run for 1st grdchk at the moment. Its unclear if
686      this is a code problem or a problem with resetting code for g_
687      variables that is being autogenerated wrong.
688      Otherwise:
689       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
690       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
691         are both still in chaos following their security messes.
692    
693    checkpoint52n_post
694    o various build (mostly genmake2) changes including:
695      - ability to build/run more easily within Cygwin and MacOS X
696      - more complicated Makefiles with a stronger dependence on Gnu Make
697  o pkg/seaice modifications  o pkg/seaice modifications
698      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
699        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
700        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
701    - changed proxy for geostrophic velocity and updated    - changed proxy for geostrophic velocity and updated
702      verification/lab_sea/results/* accordingly      verification/lab_sea/results/* accordingly
703    - removed ADI dynamic solver from pkg/seaice    - removed ADI dynamic solver from pkg/seaice
