4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o adding precip control xx_precip 32
8    o adding swflux control xx_swflux 33
9    o in natl_box_adjoint:
10      * updated exp 1 to 10
11    o enable useSingleCpuIO for mdsio vector routines
12      (applies in particular to tapelev I/O)
13    o removed inefficient K-loop in all active_file*control*.F
14    
15    checkpoint57m_post
16    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
17      and advect_cs (use EXCH-2 and standard cs-32 grid files).
18    o pkg/exch2: filling of face-corner halo regions is optional
19      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
20    
21    checkpoint57l_post
22     tag before updating tutorials (pre-release-2)
23    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
24       for output and interpolation of input fields onto model grid)
25    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
26       Affects results of exp. rotating_tank ; update output.txt.
27    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
28          and taking the square quantity and/or using a fraction-weight field.
29    o fix aim_diagnostics_init.F mate numbers.
30    o add mnc output capability to diagnostics/diagstat and update
31      our cvsignore files for the ACSII output generated
32    
33    checkpoint57k_post
34    o lab_sea now uses diagnostics package and provides a suite of
35      new EXF diagnostics output.
36    
37    checkpoint57j_post
38    o exf
39      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
40        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
41        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
42      * extended diagnostics output
43        - now includes all EXF variables
44        - hs, hl moved to common block
45        - separate S/R for diagnostics, called after ctrl vector is added
46        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
47        - EXFqnet contains true Qnet (i.e. includes qsw)
48      * updated verif. lab_sea, global_with_exf
49      * Rearranging hflux (exf_mapfields -> exf_getforcing)
50        to ensure that diagnostics sees a true EXFqnet
51    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
52    o diagnostics pkg: change pointers so that 1 diagnostic can be used
53      several times with different frequencies.
54    o mnc-ify the thsice package as requested by Daniel Enderton
55      - the monitor--MNC output needs work
56      - many attributes need to be added (most are currently blank)
57    o mnc-ify theaim_v23 package as requested by Daniel Enderton
58      - many attributes need to be added (most are currently blank)
59    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
60    o add Sadourny like discretization to the 4th.O vorticity advection scheme
61    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
62      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
63         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
64    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
65     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
66    
67    checkpoint57i_post
68    o Diagnostics package was changed: diagnostic allocation is now deactivated
69      by setting an empty file name in the namelist (used to be by setting 0 frequency)
70    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
71      add 1rst Order upwind vertical Shear.
72    o add a quick fix for A/B checkpointing in OFFLINE mode
73    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
74      end-run around the C/Fortran linking horror in eesup/src/timers.F
75    o added pkg/runclock: allows user to terminate run based on wall clock
76    o added non-hydrostatic scaling parameter: nh_am2
77    o pkg/my82: futile attempt to make results compiler-independent by adding
78      some "_d 0", etc. no effect.
79    o for mnc output, fill the 'T' coordinate var with myTime and create a
80      separate 'iter' variable for iteration count
81    o pkg/diagnostics:
82      add new capability: output of Global/Regional & per-level statistics ;
83      tested against monitor output (including land & thSIce) on various exp.
84    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
85    
86    checkpoint57h_done
87      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
88      data.diagnostics, data.gchem, data.ptracers) is done.
89    
90    o pkg/diagnostics: prepare for Global/Regional statistics.
91      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
92    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
93      and rename it: DIFFERENT_MULTIPLE
94    
95    checkpoint57h_post
96    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
97    o pkg/diagnostics: change output frequency, now in seconds (instead
98      of Nb of iterations). This requires to change data.diagnostics.
99    checkpoint57h_pre
100    
101    o in mnc, let the user create the output dir if both mnc_outdir_date
102      and mnc_outdir_num are false
103    o add fflags() to pkg/diagnostics which allows one to specify, on a
104      per-file basis, the file precision [default behavior is unchanged]
105    o added diagnostics to pkg/kpp, including computation of mixed layer
106      depth based on a temperature/density criterion
107    o updated verification/natl_box to test the new pkg/kpp diagnostics
108    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
109    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
110    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
111      not mnc -- this mistake was found by JMC and is now corrected
112    
113    checkpoint57g_post
114    o add Adams-Bashforth 3rd Order time stepping:
115      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
116      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
117    checkpoint57g_pre
118    
119    o make lambda[Theta,Salt]ClimRelax spatially varying
120      (default remains spatially uniform constant based on tau)
121    o added new control variables
122      * init. uVel, vVel, etanN
123      * lambda[Theta,Salt]ClimRelax
124    o separate masks used for ctrl_pack/unpack 'from write_grid' output
125      (suggested by G. Forget)
126    
127    checkpoint57f_post
128    o add parameter "baseTime" = model base time = time at iteration zero
129      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
130      account for baseTime shift
131    o move Coriolis arrays from PARAMS.h to GRID.h
132    checkpoint57f_pre
133    
134    o mnc-ifying the seaice package
135    o introduced an alternative length scale calculation for use in the limiting
136      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
137    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
138    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
139      as well as grad(vort3).  Made it compatible with both approximate form
140      for the cubed sphere and full form of these gradients.  Added flag
141      useFullLeith to select between approximate and full form.  
142    o add "d0" in getcon.F to reduce differences between compilers/platforms
143      update output.txt of exp. fizhi-gridalt-hs
144    o change port_rand funtion to allow to set the seed.
145    o fix obscure MNC bug involving conversion between reals and integers
146      - it caused no problems with certain (eg. gcc, ifc) compilers but the
147        new version is now more standards-compliant
148    o adjoint-related modifications
149      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
150      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
151      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
152    
153    checkpoint57e_post
154    o Adding eddy stress controls a la Ferreira et al.
155    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
156    
157    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
158      update output.txt of exp. fizhi-gridalt-hs
159    o add more "Z" dimensions and associated coordinate vars to MNC
160    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
161    o parameter calendarDumps: when set, approximate months (30-31 days) and years
162      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
163      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
164      months and years.  Requires pkg/cal.
165    o diagnostics: add pickup functionality
166      - off by default for backwards compatibility
167      - current version only uses MDSIO -- MNC will be added
168    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
169    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
170    
171    checkpoint57d_post
172    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
173    o modify verification/ideal_2D_oce so that it tests the creation of mnc
174      output from the diagnostics package
175    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
176    o make genmake2 more portable by using ".$FS" instead of ".f" for more
177      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
178    o add coordinate variables to the MNC output from the diagnostics package
179    o change MNC-flags default value: true when useMNC=TRUE
180    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
181      the ability (off by default) to read the grid information using MNC
182    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
183    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
184    o do snap-shot diagnostics at the middle of the time-interval (instead of
185      at the end).
186    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
187      new test for AIM with thSIce + slab-ocean
188    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
189    o move state variable diagnostics to the beginning of the time step ;
190      (note: still needs some work specially for snap-shot diagnostics)
191      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
192    
193    checkpoint57c_post
194    o Change testing option (-ieee) to get closer agreement between g77 & ifort
195    o generate new output.txt files on faulks with g77 & the new -ieee option
196    checkpoint57c_pre
197    
198    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
199      update output.txt of exp. global_ocean.90x40x15
200    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
201      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
202    o add saltFlux(+File) forcing capability with periodicExternalForcing
203    o allow to use pkg diagnostics for GM-Redi & ThSIce output
204    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
205    o improvements for the MNC output from DIAGNOSTICS:
206      - correct handling of the unlimitied dimension
207      - all dims now have associated coordinate variables
208      - variables located at U, V, and Corner ("Z") points are now written
209        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
210        *all* data points are output
211    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
212    o added pkg/seaice/seaice_monitor.F
213    o mdsio_readfield.F can now read files visible only to master MPI process.
214    o pkg/seaice: some test code for ice-modified ocean stress
215    o exf_getffields interpolation defaults to bilinear for all scalar forcing
216      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
217      spurious negative numbers for precipitation and humidity.  Will cause
218      some small numerical differences for integrations using pkg/exf/exf_interp.F.
219    o pkg/ctrl/
220      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
221        May be enabled via doPackDiag
222      *  introduce z-scaling of
223         + gradient (doZscalePack) and
224         + control (doZscaleUnpack)
225    o pkg/mdsio/
226      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
227      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
228    
229    checkpoint57b_post
230    o simplify options in diagnostics_fill arguments (remove weird combinations)
231    o fix MNC coordinate variables so that they now contain per-face index
232      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
233      general, EXCH2 grids are only aligned to a "local" coordinate system
234    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
235    o Implement instantaneous output within pkg diagnostics:
236      setting a negative frequency in data.diagnostics produces
237     "snap-shot" output (as opposed to time-average if freq > 0)
238    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
239      NOTE: change ptracer diagnostics name: use 2 characters to work with
240            more than 9 tracers. Add also diagnostics of advect & diffus flux.
241    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
242      becomes the coordinate variable for the 'T' dimension
243    o add CF-style coordinate variables to MNC
244      - just a first cut:  numbers are meaningless on the cubesphere and
245        missing along the T axis but otherwise it works!
246    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
247    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
248    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
249      this is based directly on what the model compute, so that the content of
250      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
251    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
252    o clean up build options files for SunOS, in particular
253      - remove -traditional from xmakedepend
254      - change -xarch=v9 to -xarch=native for f77
255      - restore use of make (not gmake)
256      - add CC=gcc if using g77
257    o changes per discussion of AM, JMC, & EH3 today:
258      - move redundant "grid" variables out of "state" -- in preparation of
259        creating proper CF-style coordinate variables and in recognition
260        that any/all grid variables can be easily copied (eg. w/NCO) from
261        the grid files into any of the other NetCDF files
262      - *always* output grid variables with MDSIO (this will eventually be
263        changed)
264      - output MNC grid file if useMNC is true
265    o every instance of _END_MASTER() has been found and replaced with
266      _END_MASTER( myThid ) in order to satisfy certain picky Sun
267      preprocessors
268    o re-arrange diagnostics pkg initialisation:
269     - allow each package to extend the available diagnostics list
270     - add some checking and fix small problems (multi-threaded, ...)
271     - new S/R diagnostics_fill (replace fill_diagnostics):
272       look through the short list of active diag. (instead of the long list)
273       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
274    
275    checkpoint57a_post
276    o this set of changes restores TAMC compatibility
277      tested for global_ocean.90x40x15 adjoint on trough
278      (what a pain)
279    
280    checkpoint57a_pre
281    o some modifs in tools/build_options for sunos
282    o call ctrl_pack for ctrl at end for optimcycle=0
283    
284    checkpoint57
285    o add horizontal bi-harmonic viscosity for vertical velocity
286      - new parameter viscA4W (defaults to viscA4)
287      - affects only non-hydrostatic code
288      - to be done: no-slip lateral boundary conditions
289    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
290    o implement Implicit Vertical advection for pTracers
291    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
292      (implemented also for implicit vertical diffusion & advection)
293    o OBCS: extend application of tracer open boundary conditions
294      to a strip beyond the boundary of width Olx/Oly
295    o add call monitor to TAF set of required calls (flow directives)
296      and include in natl_box_adjoint
297    o untangle a few ifdefs related to cost, ctrl, autodiff
298      untangel a few ALLOW_ECCO_OPTIMIZATION
299    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
300      (theta2, salt2 in ecco_cost_weights)
301    
302    checkpoint56c_post
303    o OBCS as control variables
304      - update ctrl_ad_diff.list, obcs_ad_diff.list
305      - remove balance of obcs controls from default
306      - fix index bug nobcs in ctrl_init
307      - fix dummy fields filen in ctrl_pack
308      - add dummy weights for obcs
309    o lsopt: comment out fort.94 output
310    o optim:
311      - remove unnecessary header files
312      - adjusted namelists
313      - add xerbla.F to Makefile
314    o exf:
315      - multiple modifications of exf_check_range
316      - unit change in exf_init_runoff from [m/year] to [m/s]
317    o mdsio:
318      - i/o-vector change debugLevel from debLevA to debLevB
319    
320    checkpoint56b_post
321    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
322      is called from DO_THE_MODEL_IO
323      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
324      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
325      - clean up PTRACERS_WRITE_TIMEAVE a little
326    o add another verification experiment that tests both the cfc-pkg and
327      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
328      reactive tendencies treated inline with regular timestepping
329    o testreport previously did a lousy job of comparing small numbers, so
330      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
331      implemented in the little c-progam tmp_cmpnum.c which is embedded in
332      testreport.
333    o ptracers_monitor: bug fix for MPI
334    
335    checkpoint56a_post
336    o GCHEM: finish reorganizating the package
337      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
338        (introduces another 3D-array for each passive tracer, but only if
339        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
340        gchemTendency is not needed because the timestep is done separately)
341      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
342      - GCHEM is now---more or less cleanly---separate from PTRACERS
343      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
344        so clear to me how that should be done in a general way.
345    o CFC: improve formatting of output in CFC_ATMOS
346    o PTRACERS:
347      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
348        that ALL experiments with ptracers enable can be checked. This makes
349        GCHEM_MONITOR obsolete.
350      - include a runtime parameter PTRACERS_monitorFreq that defaults to
351        monitorFreq
352      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
353    o add PTRACERS (PTR0[1-5]) to testreport output
354    o exf_check_range:
355      * default changed to .TRUE.
356      * will check values for niter0 if debLevA, every timestep if debLevB
357      * STOP in exf_check_range if 'out of range'
358      * range chosen generous to allow for potential extema
359      TBD: a version with stricter range
360           permitted range would be runtime parameters
361    o GMredi:
362      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
363      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
364      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
365    o GCHEM:
366      - move call to GCHEM_FORCING_SEP, so that it is now called before
367        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
368      - introduced a useGCHEM runtime flag and applied it everywhere.
369      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
370        this flag is now only visible within GCHEM-pkg routines.
371      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
372        be replaced by a 3D array that is computed before thermodynamics; for
373        this, the tracer ID iTracer had to be included into the parameter list
374        of ptracers_forcing
375      - set up forward_step to call gchem_forcing, that will replace
376        gchem_forcing_int in ptracers_forcing
377      - cleaning up
378    o small cleaning of exch2: remove files that are also in eesupp/src
379    
380    checkpoint56
381    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
382    o mnc: cleanup "full" files--fixes out-of-memory problem
383    o ECCO-GODAE
384      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
385      * fully merged and updated from SIO code
386        windstress sign change affects
387        - exf_inscal_[u/v]stress
388        - sign of xx_tau[u/v] adjustments
389        - signs in cost_scat
390      * ctrl_get_gen: avoid update of tau[u/v] for first few days
391      * natl_box_adjoint updated and compressed
392      * 2-level checkpoint switch added
393        (tested in EXP. 1 of natl_box_adjoint)
394      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
395    o SVD
396      * first complete, non-hacked version for SVD calculations
397      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
398        performed via direct access files admtlm_vector.it????
399        (via ctrl_[un]pack)
400      * optimcycle is used for ARPACK iteration counter
401        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
402      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
403        and add linear transforms where necessary
404      * controls are initial/final SST, SSS (can be extended; need to check
405        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
406    o mdsio: filename info to both stderr, stdout
407    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
408      from sign change
409    
410    checkpoint55j_post
411    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
412      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
413    o add consistent build directories and .cvsignore files to verification
414    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
415    o make all subroutines 30 or less characters in length for certain older
416      compilers to work (a thorough search only turns up two routines in
417      pkg/ptracers)
418    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
419      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
420    
421    checkpoint55i_post
422    o change arrays for total vertical diffusivity (2.D if explicit,
423      3.D if implicit) ; each ptracer uses its own background value.
424    o added mnc/NetCDF output capability to ocn_compon_interf
425      - added bits to verification/cpl_aim+ocn so that it can run on
426        ITRDA and other clusters without the mpirun "-wd" option
427    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
428      configuration
429    o give MNC the ability to create additional files rather than
430      exceeding a specified file size limit "MNC_MAX_FILESIZE"
431      - the default is just less than 2GB which is a practical limit
432        on many systems
433    o Compute the non-local term using either KPP vertical diffusivity (=default)
434       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
435    
436    checkpoint55h_post
437    o add verification test "vermix"
438    o remove all the *_ioinc flags and replace with the single global
439      outputTypesInclusive flag
440    o allow to set a vertical profile of vertical diffusivity for T & S
441    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
442    o useMNC moved from data.mnc to data.pkg
443    
444    checkpoint55g_post
445    o Renaming carbon AD experiments to comply with testreport conventions
446    o Updating adjoint of Held-Suarez hs94.1x64x5
447    o Fixing directives for non-ECCO forward_step, after ECCO directives
448      have been fixed to avoid recomp. of do_oceanic_phys
449      Works well for global_ocean.90x40x15,
450      but recomp. issue remains for carbon
451    o Updating adjoint output for natl_box_adjoint after
452      pkg/ecco has been modified (see taga c55d_post)
453    
454    checkpoint55f_post
455    o rename to timeave_init_fixed
456    
457    checkpoint55e_post
458    o some delicate re-shuffle of store directives to avoid one
459      extra call of do_oceanic_physics
460      affects ecco_the_main_loop.F, do_oceanic_physics.F
461      checkpoint_lev1_directives.h
462    o NB: this may break global_ocean adjoint temporarily,
463      but it is clear how to fix it. Will do later, need this now.
464    
465    checkpoint55d_post
466    o ECCO specific cost function terms (up-to-date with 1x1 runs)
467    o ecco_cost_weights is modified to 1x1 runs
468    o modifs to allow observations to be read in as
469      single file or yearly files
470    o enable to read exf forcing fields as either
471      single file or yearly files (flag useExfYearlyFields)
472    checkpoint55d_pre
473    
474    o switch between 2-level and 3-level checkpointing
475    o add ability of MNC to write local and "partial" (eg. 2D slices where
476      the full 3D field is never actually stored) arrays to NetCDF files
477      with the correct (that is, the complete multi-dimensional) set of
478      array indicies
479      - used in mom_vecinv() to write the diagFreq output
480      - tested (demonstrated) in verification/aim.5l_cs
481    o further mnc-ification
482      - add verification/lab_sea to the list with mnc setups
483      - fix undefined mnc v-names in cd_code
484      - add kpp to mnc output (both snapshot and timeave)
485    o non-hydrostatic code
486      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
487        in calc_gw.F
488      - defaults to viscAh
489      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
490        friction or Leith) in non-hydrostatic mode, as long as there is
491        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
492    o pkg/cost
493      extend simple cost functions to treat time mean quantities
494      (T,U,V) via cost_accumulate_state from cost_tile
495    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
496        be 2 times larger than the minimum size the advection scheme requires.
497        now get a perfect conservation of salt in advect_cs test-exp (updated)
498    o GGL90 (Gaspar's TKE mixed layer)
499      - add horizontal diffusion of TKE, requires exchanges in
500        do_fields_blocking_exchanges, horizontal diffusivity is zero by
501        default. In OPA there is no horizontal diffusion of TKE but the
502        mixing coefficients are computed from a horizontal average of TKE of
503        6 points or so. I think that diffusion has a little more physical
504        justification.
505      - clean up ggl90_calc in the hope of reducing memory usage (this hope
506        was in vain)
507      - mask tke-variable in ggl90_init
508    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
509    o fix biharmonic diffusion on CS-grid.
510    o more obcs stuff
511      - added obcs_external_fields_load as an alternative to the EXF-pkg option
512        for reading boundary values. This routine is called from
513        obcs_prescribe_read
514      - updated obcs_check
515      - changed sponge layer relaxation parameter units for days to seconds
516      - turned off sponge layer by default
517      - changed argument list of OBCS_CALC to myTime+deltaTclock
518      - fixed about 35 bugs in obcs_external_fields_load
519    
520    checkpoint55c_post
521    o obcs stuff
522      - new runtime flags useOBCSprescribe, useOBCSbalance
523      - re-arranged obcs_calc
524      - moved exf_getobcs to obcs_prescibe_read
525        obcs_prescibe_read is called after ORLANSKI stuff
526        and independent of it (executable can contain all).
527      - updated obcs_check
528      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
529        These may be necessary only if tangential velocities are
530        prescribed at OB, not sure, needs testing.
531    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
532      which simplifies the calls and passes the ifc check-bounds test
533    
534    checkpoint55b_post
535    o add a 2D scalar, Z location, exchange_2 routine.
536    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
537      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
538      affects advect_cs results (for the wrong reason): update output.txt
539    o use a more standard discretization for biharmonic viscosity ;
540     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
541      affects results of dome set-up: update output.txt
542    o fix gad_advection.F (CubedSphere part), back to version 1.23
543    o fix bug in mom_vi_del2uv.F (CubedSphere part).
544    
545    checkpoint55a_post
546    o merged code to
547      * prescribe/read time-dependent open boundaries
548        (works in conjunction with exf, cal)
549      * sponge layer code for open boundaries
550      * each boundary N/S/E/W now has its own CPP option
551        (healthy for the adjoint)
552    
553    checkpoint55
554    o up-to-date adjoint of previous breaks
555      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
556      - global_ocean_ebm: adjoint still needs fix (TLM ok)
557      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
558      - carbon: * remove tr1-related adjoint verification
559                * add ptracer as control variable
560    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
561      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
562    
563    checkpoint54f_post
564    o in verification/carbin/ remove experiment related to
565      ALLOW_PASSIVE_TRACER (array tr1 etc)
566      code_ad/ input_ad/ results_ad
567    
568    o add two new packages
569      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
570        + subject to optimization (memory)
571      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
572        + subject to reordering (many GOTOs in the original code)
573        + so far opps is called for every (i,j) point, and then operates in
574          the vertical; one may want to reorder the scheme in order operate in
575          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
576          fields)
577    o overhaul of IO so that we now have flags for MDSIO and/or MNC
578      - all verification tests compile and run with linux_ia32_g77
579      - defaults are compatible with current input files--nothing
580        should change if you were not previously using MNC
581      - MNC output has been added in numerous places (eg. timeave)
582        but there are still a few writes not yet do-able with MNC
583        (this is in progress)
584      - flags now allow for either/or/both use of MDSIO and MNC and
585        documentation will soon follow
586      - numerous small formatting cleanups for ProTeX
587    o add version info (via BUILD_INFO.h) to MNC and stdout
588    
589    checkpoint54e_post
590    o add two new packages
591      - pp81 (Packanowski and Philander, 1981), Richardson number and
592        stratification dependent mixing
593      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
594      - these scheme operate in a similar manner as KPP (without ghat, of
595        course), however there is only one diffusivity that is used for both
596        temperature and salinity (and passive tracers)ç
597    o add offline package
598    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
599      provided by Stephanie Dutkiewicz
600    o genmake2: add ability to search for C compilers and cleanup test output
601      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
602    
603    checkpoint54d_post
604    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
605    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
606      leading to additional shift by 5 days each year of integration
607       (i.e. leading to considerable offset over the years)
608    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
609    o start with no AB and no initial filtering (staggerTimeStep):
610      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
611    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
612      (external loading & cpl import/export stay in forward_step.F)
613    o update coupling interface to work with new staggerTimeStep
614    o change MDSIO ptracers_pickup.
615    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
616    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
617    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
618    
619    checkpoint54c_post
620    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
621      this affects (truncation error) output.txt of test-exp:
622       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
623    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
624    o change Qnet to always be the net heat flux, (+upward).
625      affects (truncation error) output of natl_box exp.: updated
626    o define the max number of passive tracers in PTRACERS_SIZE.h
627    o start to test mnc routinely in exp0
628    o add sea-ice loading (sIceLoad) as a new forcing field.
629    
630    checkpoint54b_post
631    o add testreport "-j JOBS" option for parallel builds (tested and pretty
632       impressive on Altix and Opteron systems)
633    o diagnostics can now write NetCDF files through the mnc package
634    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
635    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
636    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
637      affects (truncation error) output of lab_sea & natl_box exp.: updated
638    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
639    
640    checkpoint54a_post
641    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
642    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
643    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
644    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
645      + internal_wave (shift in writing cg2d_ini_res)
646    checkpoint54a_pre
647    
648    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
649      - modified verification/lab_sea and natl_box_adjoint accordingly
650    
651    checkpoint54
652    checkpoint53g_post
653    o prepare splitting of thermodynamics: store convect.counter in common block
654    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
655      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
656    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
657    o new parameter "nShapS": allow to treat differently S from T (nShapT)
658    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
659    o restore adjointability
660    
661    checkpoint53f_post
662    o modifications that affect AIM experiment results (update output.txt):
663      - no advection of S at top interface Nr (pkg/generic_advdiff)
664      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
665    o AIM pkg:
666      - include stability function into surf.Flux derivative relative to Tsurf
667      - calculate clear-sky radiation & surface temp. change (for diagnostics)
668    
669    checkpoint53e_post
670    o merged cylindrical coord configuration
671    o added rotating_tank experiment
672    checkpoint53e_pre
673    
674    checkpoint53d_post
675    o faulks upgraded: re-generate output.txt that have changed:
676       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
677    o Added Bryan and Lewis, 1979, vertical diffusivity profile
678    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
679    o added Sadourny discretization of Coriolis
680      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
681      - re-enabled use of omega3 (useAbsVorticity)
682    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
683      vector-invariant equations
684      - note: does *NOT* yet use same variable visc. for no-slip BC's.
685    o recoded the lateral boundary conditions for non-hydrostatic w, this time
686      hopefully without new bugs
687      - still to do: biharmonic friction for non-hydrostatic w
688    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
689    o regenerated output for global_ocean_ebm (using -ieee)
690    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
691      of mom_common/
692      - simple re-arrangement of instructions within computing loop
693    checkpoint53d_pre
694    
695    checkpoint53c_post
696    o new version of coupler for AIM+thSIce and Ocean models
697     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
698     - land: change Evaporation of snow
699     - aim with thSIce: fix bug in snow-precip.
700    o changes to calc_gw.F
701     - bug fix for w^2 term near the bottom boundary
702     - (hopefully) improve the lateral slip boundary condtions for use with
703        partial/looped cells
704      - because the bug fix changes two verification experiments anyway (exp5
705        and plume on slope), change the lateral boundary condition from half slip
706        to the value of no_slip_sides
707    o ebm package wasnt quite up to the parallel task. Fixed that.
708    o Adjoint of EBM package + verification
709      * TLM OK
710      * ADM not sufficient accuracy yet (needs further testing)
711    
712    checkpoint53b_post
713    o Commiting new energy balance model to repository
714      * package is pkg/ebm
715      * verif. is verification/global_ocean_ebm
716      * references are in ebm_driver.F
717    C      * X. Wang, P. Stone and J. Marotzke, 1999:
718    C        Global thermohaline circulation. Part I:
719    C        Sensitivity to atmospheric moisture transport.
720    C        J. Climate 12(1), 71-82
721    C      * X. Wang, P. Stone and J. Marotzke, 1999:
722    C        Global thermohaline circulation. Part II:
723    C        Sensitivity with interactive transport.
724    C        J. Climate 12(1), 83-91
725    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
726    C        Destabilization of the thermohaline circulation
727    C        by atmospheric eddy transports.
728    C        J. Climate 7(12), 1870-1882
729    o Will need long integration testing.
730    checkpoint53b_pre
731    
732    o created pkg/mom_common in preparation for variable viscosity code
733    o renamed and split ini_mnc_io
734    o pkg/land: only liquid water can diffuse or run-off
735    o AIM using land: soil wetness availability account for snow
736    o added printMapIncludesZeros to EEPARMS namelist
737    
738    checkpoint53a_post
739    o restore TAMC compatiility for exf_constants.h
740      (no usage of _d in .h)
741    o Additional storing in KPP in an attempt to fix
742      TAMC problem with adjoint of KPP code.
743      (no success...)
744      Identical code works fine with TAF.
745    o Fixed verification/natl_box_adjoint experiments.
746      Initial conditions for Experiments 4 and 5 are now
747      set to "SEAICE_initialHEFF=0", which is more reasonable,
748      and hence gives results closer to that of Experiment 2.
749      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
750    
751    checkpoint53
752    o stable checkpoint with up to date adjoint
753      TLM tests only run for 1st grdchk at the moment. Its unclear if
754      this is a code problem or a problem with resetting code for g_
755      variables that is being autogenerated wrong.
756      Otherwise:
757       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
758       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
759         are both still in chaos following their security messes.
760    
761    checkpoint52n_post
762    o various build (mostly genmake2) changes including:
763      - ability to build/run more easily within Cygwin and MacOS X
764      - more complicated Makefiles with a stronger dependence on Gnu Make
765    o pkg/seaice modifications
766      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
767        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
768        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
769      - changed proxy for geostrophic velocity and updated
770        verification/lab_sea/results/* accordingly
771      - removed ADI dynamic solver from pkg/seaice
772      - replaced all occurrences of 1/CSTICE or 1/CSUICE
773        they caused a segmentation fault under certain circumstances
774      - removed unused field WATR
775    o bug fix in exf-package:
776      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
777         now reflect that.
778    o small fixes in the cal-package:
779      - set reference date to first of January for the 'model'-calendar
780      - failing of cal_CheckDate in cal_FullDate now actually results in a
781        warning
782    o small modifications in exf-package to increase flexibility:
783      - change climtempfreeze from a constant to a runtime parameter that
784        is specified in data.exf_clim (default = -1.9)
785      - introduce runtime parameter windstressmax (default = 2.0) that is
786        specified in data.exf
787  o fix in pkg/thsice:  o fix in pkg/thsice:
788    - update Evap (Tsf changes) to be consistent with Latent heat flux    - update Evap (Tsf changes) to be consistent with Latent heat flux
789    - maintain snow precipitation unchanged (even if Tsf >=0).    - maintain snow precipitation unchanged (even if Tsf >=0).
