5      ==============================      ==============================
6    
7    o In response to JMC's bug report, genmake2 now ignores any soft-links
8      that it finds in the *current* directory when searching for files.
9      Soft-links found in any other source directories will still work as
10      they did before.
11    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
12      a C routine to unlimit the stack size
13    o mnc-ify pkg/aim snapshot vars
14    o mnc-ify pkg/land as requested by Daniel
15    o various changes to mnc including:
16      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
17      - output can now be grouped so that all files within a group
18          change the ITER portion of their names in lock-step together
19      - can now read ("global") PER-FACE (in addition to PER-TILE) files
20          and works with both EXCH1 and EXCH2 (but needs more testing)
21      - writing works for all verification test cases w/ g77 on Linux
22    
23    checkpoint57r_post
24    o make MNC variable initialization happen earlier
25    o add diagnostics for (almost) each term of the momentum Eq.
26    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
27    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
28    o remove MINIMAL_TAVE_OUTPUT option ;
29      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
30    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
31      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
32    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
33    o add time-dependent SST, SSS control
34    o cost terms in ecco/ modularized (new cost_generic.F)
35    o cost_averages routines are modularized (new cost_averagesgeneric.F)
36    o new infrastructure for seaice model vs. obs misfits in seaice/
37      * driver from the_main_loop.F is seaice_cost_driver.F
38      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
39      * gradient check in Exp. 6a of natl_box_adjoint/
40    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
41      (see README file)
42    
43    checkpoint57q_post
44    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
45    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
46      - bug was reported by Jean-Michel and Ian Fenty
47    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
48      update exp. cpl_aim+ocn output.
49    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
50      Needed for high-res. runs with large global files
51      to be able to limit tapelev size
52    o Changed some tests for adjoint:
53      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
54      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
55      * global_ocean.90x40x15/ back to default 3-level checkpointing
56    o Modifications to enable scripted COMMON to MODULE conversion
57      * verification/OpenAD/code/ has necessary scripts and description;
58      * converts, compiles and runs successfully;
59    
60    checkpoint57p_post
61    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
62    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
63      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
64    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
65    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
66      (was already the case for dissipation with mom_vecinv,
67       and also the case for grad.PhiHyd when staggered-timeStep)
68      This will allow to put dissipation out-off the AB time-stepping.
69     Unfortunately, affects truncation error. Update output of exp. that "fails"
70      (cg2d matching number) and leave the others for later: front_relax(10),
71      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
72      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
73    
74    checkpoint57o_post
75    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
76      (2) its ready to be documented during the 20050801 DocFest
77    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
78      for ideal_2D_oce and lab_sea on linux_ia32_g77
79    o set to #undef CTRL_SET_OLD_MAXCVARS_30
80      in global1x1_tot/code_seaice_adj to access indices 32, 33
81      (worth another tag)
82    
83    checkpoint57n_post
84    o adding precip control xx_precip 32
85    o adding swflux control xx_swflux 33
86    o Replacing 10 forcing penalty cost routines by 1 generic.
87    o Implementing partitioning in time-mean and variable adjustment
88      for atmos. state.
89    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
90    o in natl_box_adjoint:
91      * updated exp 1 to 10
92        (but does not have time-mean vs. variable split results yet)
93    o updated global1x1/*_seaice_adj/
94      to incorporate latest changes
95    o enable useSingleCpuIO for mdsio vector routines
96      (applies in particular to tapelev I/O)
97    o removed inefficient K-loop in all active_file*control*.F
98    
99    checkpoint57m_post
100    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
101      and advect_cs (use EXCH-2 and standard cs-32 grid files).
102    o pkg/exch2: filling of face-corner halo regions is optional
103      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
104    
105    checkpoint57l_post
106     tag before updating tutorials (pre-release-2)
107    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
108       for output and interpolation of input fields onto model grid)
109    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
110       Affects results of exp. rotating_tank ; update output.txt.
111    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
112          and taking the square quantity and/or using a fraction-weight field.
113    o fix aim_diagnostics_init.F mate numbers.
114    o add mnc output capability to diagnostics/diagstat and update
115      our cvsignore files for the ACSII output generated
116    
117    checkpoint57k_post
118    o lab_sea now uses diagnostics package and provides a suite of
119      new EXF diagnostics output.
120    
121    checkpoint57j_post
122    o exf
123      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
124        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
125        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
126      * extended diagnostics output
127        - now includes all EXF variables
128        - hs, hl moved to common block
129        - separate S/R for diagnostics, called after ctrl vector is added
130        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
131        - EXFqnet contains true Qnet (i.e. includes qsw)
132      * updated verif. lab_sea, global_with_exf
133      * Rearranging hflux (exf_mapfields -> exf_getforcing)
134        to ensure that diagnostics sees a true EXFqnet
135    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
136    o diagnostics pkg: change pointers so that 1 diagnostic can be used
137      several times with different frequencies.
138    o mnc-ify the thsice package as requested by Daniel Enderton
139      - the monitor--MNC output needs work
140      - many attributes need to be added (most are currently blank)
141    o mnc-ify theaim_v23 package as requested by Daniel Enderton
142      - many attributes need to be added (most are currently blank)
143    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
144    o add Sadourny like discretization to the 4th.O vorticity advection scheme
145    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
146      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
147         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
148    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
149     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
150    
151    checkpoint57i_post
152    o Diagnostics package was changed: diagnostic allocation is now deactivated
153      by setting an empty file name in the namelist (used to be by setting 0 frequency)
154    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
155      add 1rst Order upwind vertical Shear.
156    o add a quick fix for A/B checkpointing in OFFLINE mode
157    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
158      end-run around the C/Fortran linking horror in eesup/src/timers.F
159    o added pkg/runclock: allows user to terminate run based on wall clock
160    o added non-hydrostatic scaling parameter: nh_am2
161    o pkg/my82: futile attempt to make results compiler-independent by adding
162      some "_d 0", etc. no effect.
163    o for mnc output, fill the 'T' coordinate var with myTime and create a
164      separate 'iter' variable for iteration count
165    o pkg/diagnostics:
166      add new capability: output of Global/Regional & per-level statistics ;
167      tested against monitor output (including land & thSIce) on various exp.
168    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
169    
170    checkpoint57h_done
171      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
172      data.diagnostics, data.gchem, data.ptracers) is done.
173    
174    o pkg/diagnostics: prepare for Global/Regional statistics.
175      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
176    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
177      and rename it: DIFFERENT_MULTIPLE
178    
179    checkpoint57h_post
180    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
181    o pkg/diagnostics: change output frequency, now in seconds (instead
182      of Nb of iterations). This requires to change data.diagnostics.
183    checkpoint57h_pre
184    
185    o in mnc, let the user create the output dir if both mnc_outdir_date
186      and mnc_outdir_num are false
187    o add fflags() to pkg/diagnostics which allows one to specify, on a
188      per-file basis, the file precision [default behavior is unchanged]
189    o added diagnostics to pkg/kpp, including computation of mixed layer
190      depth based on a temperature/density criterion
191    o updated verification/natl_box to test the new pkg/kpp diagnostics
192    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
193    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
194    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
195      not mnc -- this mistake was found by JMC and is now corrected
196    
197    checkpoint57g_post
198    o add Adams-Bashforth 3rd Order time stepping:
199      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
200      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
201    checkpoint57g_pre
202    
203    o make lambda[Theta,Salt]ClimRelax spatially varying
204      (default remains spatially uniform constant based on tau)
205    o added new control variables
206      * init. uVel, vVel, etanN
207      * lambda[Theta,Salt]ClimRelax
208    o separate masks used for ctrl_pack/unpack 'from write_grid' output
209      (suggested by G. Forget)
210    
211    checkpoint57f_post
212    o add parameter "baseTime" = model base time = time at iteration zero
213      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
214      account for baseTime shift
215    o move Coriolis arrays from PARAMS.h to GRID.h
216    checkpoint57f_pre
217    
218    o mnc-ifying the seaice package
219    o introduced an alternative length scale calculation for use in the limiting
220      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
221    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
222    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
223      as well as grad(vort3).  Made it compatible with both approximate form
224      for the cubed sphere and full form of these gradients.  Added flag
225      useFullLeith to select between approximate and full form.  
226    o add "d0" in getcon.F to reduce differences between compilers/platforms
227      update output.txt of exp. fizhi-gridalt-hs
228    o change port_rand funtion to allow to set the seed.
229    o fix obscure MNC bug involving conversion between reals and integers
230      - it caused no problems with certain (eg. gcc, ifc) compilers but the
231        new version is now more standards-compliant
232    o adjoint-related modifications
233      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
234      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
235      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
236    
237    checkpoint57e_post
238    o Adding eddy stress controls a la Ferreira et al.
239    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
240    
241    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
242      update output.txt of exp. fizhi-gridalt-hs
243    o add more "Z" dimensions and associated coordinate vars to MNC
244    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
245    o parameter calendarDumps: when set, approximate months (30-31 days) and years
246      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
247      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
248      months and years.  Requires pkg/cal.
249    o diagnostics: add pickup functionality
250      - off by default for backwards compatibility
251      - current version only uses MDSIO -- MNC will be added
252    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
253    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
254    
255    checkpoint57d_post
256    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
257    o modify verification/ideal_2D_oce so that it tests the creation of mnc
258      output from the diagnostics package
259    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
260    o make genmake2 more portable by using ".$FS" instead of ".f" for more
261      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
262    o add coordinate variables to the MNC output from the diagnostics package
263    o change MNC-flags default value: true when useMNC=TRUE
264    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
265      the ability (off by default) to read the grid information using MNC
266    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
267    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
268    o do snap-shot diagnostics at the middle of the time-interval (instead of
269      at the end).
270    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
271      new test for AIM with thSIce + slab-ocean
272    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
273    o move state variable diagnostics to the beginning of the time step ;
274      (note: still needs some work specially for snap-shot diagnostics)
275      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
276    
277    checkpoint57c_post
278    o Change testing option (-ieee) to get closer agreement between g77 & ifort
279    o generate new output.txt files on faulks with g77 & the new -ieee option
280    checkpoint57c_pre
281    
282    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
283      update output.txt of exp. global_ocean.90x40x15
284    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
285      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
286    o add saltFlux(+File) forcing capability with periodicExternalForcing
287    o allow to use pkg diagnostics for GM-Redi & ThSIce output
288    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
289    o improvements for the MNC output from DIAGNOSTICS:
290      - correct handling of the unlimitied dimension
291      - all dims now have associated coordinate variables
292      - variables located at U, V, and Corner ("Z") points are now written
293        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
294        *all* data points are output
295    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
296    o added pkg/seaice/seaice_monitor.F
297    o mdsio_readfield.F can now read files visible only to master MPI process.
298    o pkg/seaice: some test code for ice-modified ocean stress
299    o exf_getffields interpolation defaults to bilinear for all scalar forcing
300      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
301      spurious negative numbers for precipitation and humidity.  Will cause
302      some small numerical differences for integrations using pkg/exf/exf_interp.F.
303    o pkg/ctrl/
304      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
305        May be enabled via doPackDiag
306      *  introduce z-scaling of
307         + gradient (doZscalePack) and
308         + control (doZscaleUnpack)
309    o pkg/mdsio/
310      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
311      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
312    
313    checkpoint57b_post
314    o simplify options in diagnostics_fill arguments (remove weird combinations)
315    o fix MNC coordinate variables so that they now contain per-face index
316      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
317      general, EXCH2 grids are only aligned to a "local" coordinate system
318    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
319    o Implement instantaneous output within pkg diagnostics:
320      setting a negative frequency in data.diagnostics produces
321     "snap-shot" output (as opposed to time-average if freq > 0)
322    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
323      NOTE: change ptracer diagnostics name: use 2 characters to work with
324            more than 9 tracers. Add also diagnostics of advect & diffus flux.
325    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
326      becomes the coordinate variable for the 'T' dimension
327    o add CF-style coordinate variables to MNC
328      - just a first cut:  numbers are meaningless on the cubesphere and
329        missing along the T axis but otherwise it works!
330    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
331    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
332    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
333      this is based directly on what the model compute, so that the content of
334      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
335    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
336    o clean up build options files for SunOS, in particular
337      - remove -traditional from xmakedepend
338      - change -xarch=v9 to -xarch=native for f77
339      - restore use of make (not gmake)
340      - add CC=gcc if using g77
341    o changes per discussion of AM, JMC, & EH3 today:
342      - move redundant "grid" variables out of "state" -- in preparation of
343        creating proper CF-style coordinate variables and in recognition
344        that any/all grid variables can be easily copied (eg. w/NCO) from
345        the grid files into any of the other NetCDF files
346      - *always* output grid variables with MDSIO (this will eventually be
347        changed)
348      - output MNC grid file if useMNC is true
349    o every instance of _END_MASTER() has been found and replaced with
350      _END_MASTER( myThid ) in order to satisfy certain picky Sun
351      preprocessors
352    o re-arrange diagnostics pkg initialisation:
353     - allow each package to extend the available diagnostics list
354     - add some checking and fix small problems (multi-threaded, ...)
355     - new S/R diagnostics_fill (replace fill_diagnostics):
356       look through the short list of active diag. (instead of the long list)
357       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
358    
359    checkpoint57a_post
360    o this set of changes restores TAMC compatibility
361      tested for global_ocean.90x40x15 adjoint on trough
362      (what a pain)
363    
364    checkpoint57a_pre
365    o some modifs in tools/build_options for sunos
366    o call ctrl_pack for ctrl at end for optimcycle=0
367    
368    checkpoint57
369    o add horizontal bi-harmonic viscosity for vertical velocity
370      - new parameter viscA4W (defaults to viscA4)
371      - affects only non-hydrostatic code
372      - to be done: no-slip lateral boundary conditions
373    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
374    o implement Implicit Vertical advection for pTracers
375    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
376      (implemented also for implicit vertical diffusion & advection)
377    o OBCS: extend application of tracer open boundary conditions
378      to a strip beyond the boundary of width Olx/Oly
379    o add call monitor to TAF set of required calls (flow directives)
380      and include in natl_box_adjoint
381    o untangle a few ifdefs related to cost, ctrl, autodiff
382      untangel a few ALLOW_ECCO_OPTIMIZATION
383    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
384      (theta2, salt2 in ecco_cost_weights)
385    
386    checkpoint56c_post
387    o OBCS as control variables
388      - update ctrl_ad_diff.list, obcs_ad_diff.list
389      - remove balance of obcs controls from default
390      - fix index bug nobcs in ctrl_init
391      - fix dummy fields filen in ctrl_pack
392      - add dummy weights for obcs
393    o lsopt: comment out fort.94 output
394    o optim:
395      - remove unnecessary header files
396      - adjusted namelists
397      - add xerbla.F to Makefile
398    o exf:
399      - multiple modifications of exf_check_range
400      - unit change in exf_init_runoff from [m/year] to [m/s]
401    o mdsio:
402      - i/o-vector change debugLevel from debLevA to debLevB
403    
404    checkpoint56b_post
405    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
406      is called from DO_THE_MODEL_IO
407      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
408      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
409      - clean up PTRACERS_WRITE_TIMEAVE a little
410    o add another verification experiment that tests both the cfc-pkg and
411      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
412      reactive tendencies treated inline with regular timestepping
413    o testreport previously did a lousy job of comparing small numbers, so
414      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
415      implemented in the little c-progam tmp_cmpnum.c which is embedded in
416      testreport.
417    o ptracers_monitor: bug fix for MPI
418    
419    checkpoint56a_post
420    o GCHEM: finish reorganizating the package
421      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
422        (introduces another 3D-array for each passive tracer, but only if
423        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
424        gchemTendency is not needed because the timestep is done separately)
425      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
426      - GCHEM is now---more or less cleanly---separate from PTRACERS
427      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
428        so clear to me how that should be done in a general way.
429    o CFC: improve formatting of output in CFC_ATMOS
430    o PTRACERS:
431      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
432        that ALL experiments with ptracers enable can be checked. This makes
433        GCHEM_MONITOR obsolete.
434      - include a runtime parameter PTRACERS_monitorFreq that defaults to
435        monitorFreq
436      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
437    o add PTRACERS (PTR0[1-5]) to testreport output
438    o exf_check_range:
439      * default changed to .TRUE.
440      * will check values for niter0 if debLevA, every timestep if debLevB
441      * STOP in exf_check_range if 'out of range'
442      * range chosen generous to allow for potential extema
443      TBD: a version with stricter range
444           permitted range would be runtime parameters
445    o GMredi:
446      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
447      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
448      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
449    o GCHEM:
450      - move call to GCHEM_FORCING_SEP, so that it is now called before
451        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
452      - introduced a useGCHEM runtime flag and applied it everywhere.
453      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
454        this flag is now only visible within GCHEM-pkg routines.
455      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
456        be replaced by a 3D array that is computed before thermodynamics; for
457        this, the tracer ID iTracer had to be included into the parameter list
458        of ptracers_forcing
459      - set up forward_step to call gchem_forcing, that will replace
460        gchem_forcing_int in ptracers_forcing
461      - cleaning up
462    o small cleaning of exch2: remove files that are also in eesupp/src
463    
464    checkpoint56
465    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
466    o mnc: cleanup "full" files--fixes out-of-memory problem
467    o ECCO-GODAE
468      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
469      * fully merged and updated from SIO code
470        windstress sign change affects
471        - exf_inscal_[u/v]stress
472        - sign of xx_tau[u/v] adjustments
473        - signs in cost_scat
474      * ctrl_get_gen: avoid update of tau[u/v] for first few days
475      * natl_box_adjoint updated and compressed
476      * 2-level checkpoint switch added
477        (tested in EXP. 1 of natl_box_adjoint)
478      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
479    o SVD
480      * first complete, non-hacked version for SVD calculations
481      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
482        performed via direct access files admtlm_vector.it????
483        (via ctrl_[un]pack)
484      * optimcycle is used for ARPACK iteration counter
485        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
486      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
487        and add linear transforms where necessary
488      * controls are initial/final SST, SSS (can be extended; need to check
489        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
490    o mdsio: filename info to both stderr, stdout
491    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
492      from sign change
493    
494    checkpoint55j_post
495    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
496      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
497    o add consistent build directories and .cvsignore files to verification
498    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
499    o make all subroutines 30 or less characters in length for certain older
500      compilers to work (a thorough search only turns up two routines in
501      pkg/ptracers)
502    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
503      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
504    
505    checkpoint55i_post
506    o change arrays for total vertical diffusivity (2.D if explicit,
507      3.D if implicit) ; each ptracer uses its own background value.
508    o added mnc/NetCDF output capability to ocn_compon_interf
509      - added bits to verification/cpl_aim+ocn so that it can run on
510        ITRDA and other clusters without the mpirun "-wd" option
511    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
512      configuration
513    o give MNC the ability to create additional files rather than
514      exceeding a specified file size limit "MNC_MAX_FILESIZE"
515      - the default is just less than 2GB which is a practical limit
516        on many systems
517    o Compute the non-local term using either KPP vertical diffusivity (=default)
518       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
519    
520    checkpoint55h_post
521    o add verification test "vermix"
522    o remove all the *_ioinc flags and replace with the single global
523      outputTypesInclusive flag
524    o allow to set a vertical profile of vertical diffusivity for T & S
525    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
526    o useMNC moved from data.mnc to data.pkg
527    
528    checkpoint55g_post
529    o Renaming carbon AD experiments to comply with testreport conventions
530    o Updating adjoint of Held-Suarez hs94.1x64x5
531    o Fixing directives for non-ECCO forward_step, after ECCO directives
532      have been fixed to avoid recomp. of do_oceanic_phys
533      Works well for global_ocean.90x40x15,
534      but recomp. issue remains for carbon
535    o Updating adjoint output for natl_box_adjoint after
536      pkg/ecco has been modified (see taga c55d_post)
537    
538    checkpoint55f_post
539    o rename to timeave_init_fixed
540    
541    checkpoint55e_post
542    o some delicate re-shuffle of store directives to avoid one
543      extra call of do_oceanic_physics
544      affects ecco_the_main_loop.F, do_oceanic_physics.F
545      checkpoint_lev1_directives.h
546    o NB: this may break global_ocean adjoint temporarily,
547      but it is clear how to fix it. Will do later, need this now.
548    
549    checkpoint55d_post
550    o ECCO specific cost function terms (up-to-date with 1x1 runs)
551    o ecco_cost_weights is modified to 1x1 runs
552    o modifs to allow observations to be read in as
553      single file or yearly files
554    o enable to read exf forcing fields as either
555      single file or yearly files (flag useExfYearlyFields)
556    checkpoint55d_pre
557    
558    o switch between 2-level and 3-level checkpointing
559    o add ability of MNC to write local and "partial" (eg. 2D slices where
560      the full 3D field is never actually stored) arrays to NetCDF files
561      with the correct (that is, the complete multi-dimensional) set of
562      array indicies
563      - used in mom_vecinv() to write the diagFreq output
564      - tested (demonstrated) in verification/aim.5l_cs
565    o further mnc-ification
566      - add verification/lab_sea to the list with mnc setups
567      - fix undefined mnc v-names in cd_code
568      - add kpp to mnc output (both snapshot and timeave)
569    o non-hydrostatic code
570      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
571        in calc_gw.F
572      - defaults to viscAh
573      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
574        friction or Leith) in non-hydrostatic mode, as long as there is
575        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
576    o pkg/cost
577      extend simple cost functions to treat time mean quantities
578      (T,U,V) via cost_accumulate_state from cost_tile
579    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
580        be 2 times larger than the minimum size the advection scheme requires.
581        now get a perfect conservation of salt in advect_cs test-exp (updated)
582    o GGL90 (Gaspar's TKE mixed layer)
583      - add horizontal diffusion of TKE, requires exchanges in
584        do_fields_blocking_exchanges, horizontal diffusivity is zero by
585        default. In OPA there is no horizontal diffusion of TKE but the
586        mixing coefficients are computed from a horizontal average of TKE of
587        6 points or so. I think that diffusion has a little more physical
588        justification.
589      - clean up ggl90_calc in the hope of reducing memory usage (this hope
590        was in vain)
591      - mask tke-variable in ggl90_init
592    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
593    o fix biharmonic diffusion on CS-grid.
594    o more obcs stuff
595      - added obcs_external_fields_load as an alternative to the EXF-pkg option
596        for reading boundary values. This routine is called from
597        obcs_prescribe_read
598      - updated obcs_check
599      - changed sponge layer relaxation parameter units for days to seconds
600      - turned off sponge layer by default
601      - changed argument list of OBCS_CALC to myTime+deltaTclock
602      - fixed about 35 bugs in obcs_external_fields_load
603    
604    checkpoint55c_post
605    o obcs stuff
606      - new runtime flags useOBCSprescribe, useOBCSbalance
607      - re-arranged obcs_calc
608      - moved exf_getobcs to obcs_prescibe_read
609        obcs_prescibe_read is called after ORLANSKI stuff
610        and independent of it (executable can contain all).
611      - updated obcs_check
612      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
613        These may be necessary only if tangential velocities are
614        prescribed at OB, not sure, needs testing.
615    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
616      which simplifies the calls and passes the ifc check-bounds test
617    
618    checkpoint55b_post
619    o add a 2D scalar, Z location, exchange_2 routine.
620    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
621      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
622      affects advect_cs results (for the wrong reason): update output.txt
623    o use a more standard discretization for biharmonic viscosity ;
624     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
625      affects results of dome set-up: update output.txt
626    o fix gad_advection.F (CubedSphere part), back to version 1.23
627    o fix bug in mom_vi_del2uv.F (CubedSphere part).
628    
629    checkpoint55a_post
630    o merged code to
631      * prescribe/read time-dependent open boundaries
632        (works in conjunction with exf, cal)
633      * sponge layer code for open boundaries
634      * each boundary N/S/E/W now has its own CPP option
635        (healthy for the adjoint)
636    
637    checkpoint55
638    o up-to-date adjoint of previous breaks
639      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
640      - global_ocean_ebm: adjoint still needs fix (TLM ok)
641      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
642      - carbon: * remove tr1-related adjoint verification
643                * add ptracer as control variable
644    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
645      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
646    
647    checkpoint54f_post
648    o in verification/carbin/ remove experiment related to
649      ALLOW_PASSIVE_TRACER (array tr1 etc)
650      code_ad/ input_ad/ results_ad
651    
652    o add two new packages
653      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
654        + subject to optimization (memory)
655      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
656        + subject to reordering (many GOTOs in the original code)
657        + so far opps is called for every (i,j) point, and then operates in
658          the vertical; one may want to reorder the scheme in order operate in
659          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
660          fields)
661    o overhaul of IO so that we now have flags for MDSIO and/or MNC
662      - all verification tests compile and run with linux_ia32_g77
663      - defaults are compatible with current input files--nothing
664        should change if you were not previously using MNC
665      - MNC output has been added in numerous places (eg. timeave)
666        but there are still a few writes not yet do-able with MNC
667        (this is in progress)
668      - flags now allow for either/or/both use of MDSIO and MNC and
669        documentation will soon follow
670      - numerous small formatting cleanups for ProTeX
671    o add version info (via BUILD_INFO.h) to MNC and stdout
672    
673    checkpoint54e_post
674    o add two new packages
675      - pp81 (Packanowski and Philander, 1981), Richardson number and
676        stratification dependent mixing
677      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
678      - these scheme operate in a similar manner as KPP (without ghat, of
679        course), however there is only one diffusivity that is used for both
680        temperature and salinity (and passive tracers)ç
681    o add offline package
682    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
683      provided by Stephanie Dutkiewicz
684    o genmake2: add ability to search for C compilers and cleanup test output
685      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
686    
687    checkpoint54d_post
688    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
689    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
690      leading to additional shift by 5 days each year of integration
691       (i.e. leading to considerable offset over the years)
692    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
693    o start with no AB and no initial filtering (staggerTimeStep):
694      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
695    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
696      (external loading & cpl import/export stay in forward_step.F)
697    o update coupling interface to work with new staggerTimeStep
698    o change MDSIO ptracers_pickup.
699    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
700    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
701    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
702    
703    checkpoint54c_post
704    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
705      this affects (truncation error) output.txt of test-exp:
706       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
707    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
708    o change Qnet to always be the net heat flux, (+upward).
709      affects (truncation error) output of natl_box exp.: updated
710    o define the max number of passive tracers in PTRACERS_SIZE.h
711    o start to test mnc routinely in exp0
712    o add sea-ice loading (sIceLoad) as a new forcing field.
713    
714    checkpoint54b_post
715    o add testreport "-j JOBS" option for parallel builds (tested and pretty
716       impressive on Altix and Opteron systems)
717    o diagnostics can now write NetCDF files through the mnc package
718    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
719    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
720    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
721      affects (truncation error) output of lab_sea & natl_box exp.: updated
722    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
723    
724    checkpoint54a_post
725    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
726    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
727    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
728    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
729      + internal_wave (shift in writing cg2d_ini_res)
730    checkpoint54a_pre
731    
732    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
733      - modified verification/lab_sea and natl_box_adjoint accordingly
734    
735    checkpoint54
736    checkpoint53g_post
737    o prepare splitting of thermodynamics: store convect.counter in common block
738    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
739      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
740    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
741    o new parameter "nShapS": allow to treat differently S from T (nShapT)
742    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
743    o restore adjointability
744    
745    checkpoint53f_post
746    o modifications that affect AIM experiment results (update output.txt):
747      - no advection of S at top interface Nr (pkg/generic_advdiff)
748      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
749    o AIM pkg:
750      - include stability function into surf.Flux derivative relative to Tsurf
751      - calculate clear-sky radiation & surface temp. change (for diagnostics)
752    
753    checkpoint53e_post
754    o merged cylindrical coord configuration
755    o added rotating_tank experiment
756    checkpoint53e_pre
757    
758    checkpoint53d_post
759    o faulks upgraded: re-generate output.txt that have changed:
760       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
761    o Added Bryan and Lewis, 1979, vertical diffusivity profile
762    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
763    o added Sadourny discretization of Coriolis
764      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
765      - re-enabled use of omega3 (useAbsVorticity)
766    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
767      vector-invariant equations
768      - note: does *NOT* yet use same variable visc. for no-slip BC's.
769    o recoded the lateral boundary conditions for non-hydrostatic w, this time
770      hopefully without new bugs
771      - still to do: biharmonic friction for non-hydrostatic w
772    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
773    o regenerated output for global_ocean_ebm (using -ieee)
774    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
775      of mom_common/
776      - simple re-arrangement of instructions within computing loop
777    checkpoint53d_pre
778    
779    checkpoint53c_post
780    o new version of coupler for AIM+thSIce and Ocean models
781     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
782     - land: change Evaporation of snow
783     - aim with thSIce: fix bug in snow-precip.
784    o changes to calc_gw.F
785     - bug fix for w^2 term near the bottom boundary
786     - (hopefully) improve the lateral slip boundary condtions for use with
787        partial/looped cells
788      - because the bug fix changes two verification experiments anyway (exp5
789        and plume on slope), change the lateral boundary condition from half slip
790        to the value of no_slip_sides
791    o ebm package wasnt quite up to the parallel task. Fixed that.
792    o Adjoint of EBM package + verification
793      * TLM OK
794      * ADM not sufficient accuracy yet (needs further testing)
795    
796    checkpoint53b_post
797    o Commiting new energy balance model to repository
798      * package is pkg/ebm
799      * verif. is verification/global_ocean_ebm
800      * references are in ebm_driver.F
801    C      * X. Wang, P. Stone and J. Marotzke, 1999:
802    C        Global thermohaline circulation. Part I:
803    C        Sensitivity to atmospheric moisture transport.
804    C        J. Climate 12(1), 71-82
805    C      * X. Wang, P. Stone and J. Marotzke, 1999:
806    C        Global thermohaline circulation. Part II:
807    C        Sensitivity with interactive transport.
808    C        J. Climate 12(1), 83-91
809    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
810    C        Destabilization of the thermohaline circulation
811    C        by atmospheric eddy transports.
812    C        J. Climate 7(12), 1870-1882
813    o Will need long integration testing.
814    checkpoint53b_pre
815    
816    o created pkg/mom_common in preparation for variable viscosity code
817    o renamed and split ini_mnc_io
818    o pkg/land: only liquid water can diffuse or run-off
819    o AIM using land: soil wetness availability account for snow
820    o added printMapIncludesZeros to EEPARMS namelist
821    
822    checkpoint53a_post
823    o restore TAMC compatiility for exf_constants.h
824      (no usage of _d in .h)
825    o Additional storing in KPP in an attempt to fix
826      TAMC problem with adjoint of KPP code.
827      (no success...)
828      Identical code works fine with TAF.
829    o Fixed verification/natl_box_adjoint experiments.
830      Initial conditions for Experiments 4 and 5 are now
831      set to "SEAICE_initialHEFF=0", which is more reasonable,
832      and hence gives results closer to that of Experiment 2.
833      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
834    
835    checkpoint53
836    o stable checkpoint with up to date adjoint
837      TLM tests only run for 1st grdchk at the moment. Its unclear if
838      this is a code problem or a problem with resetting code for g_
839      variables that is being autogenerated wrong.
840      Otherwise:
841       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
842       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
843         are both still in chaos following their security messes.
844    
845    checkpoint52n_post
846    o various build (mostly genmake2) changes including:
847      - ability to build/run more easily within Cygwin and MacOS X
848      - more complicated Makefiles with a stronger dependence on Gnu Make
849  o pkg/seaice modifications  o pkg/seaice modifications
850    - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost    - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
851      of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer      of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
