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