5      ==============================      ==============================
6    
7    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
8      a C routine to unlimit the stack size
9    o mnc-ify pkg/aim snapshot vars
10    o mnc-ify pkg/land as requested by Daniel
11    o various changes to mnc including:
12      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
13      - output can now be grouped so that all files within a group
14          change the ITER portion of their names in lock-step together
15      - can now read ("global") PER-FACE (in addition to PER-TILE) files
16          and works with both EXCH1 and EXCH2 (but needs more testing)
17      - writing works for all verification test cases w/ g77 on Linux
18    
19    checkpoint57r_post
20    o make MNC variable initialization happen earlier
21    o add diagnostics for (almost) each term of the momentum Eq.
22    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
23    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
24    o remove MINIMAL_TAVE_OUTPUT option ;
25      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
26    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
27      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
28    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
29    o add time-dependent SST, SSS control
30    o cost terms in ecco/ modularized (new cost_generic.F)
31    o cost_averages routines are modularized (new cost_averagesgeneric.F)
32    o new infrastructure for seaice model vs. obs misfits in seaice/
33      * driver from the_main_loop.F is seaice_cost_driver.F
34      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
35      * gradient check in Exp. 6a of natl_box_adjoint/
36    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
37      (see README file)
38    
39    checkpoint57q_post
40    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
41    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
42      - bug was reported by Jean-Michel and Ian Fenty
43    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
44      update exp. cpl_aim+ocn output.
45    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
46      Needed for high-res. runs with large global files
47      to be able to limit tapelev size
48    o Changed some tests for adjoint:
49      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
50      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
51      * global_ocean.90x40x15/ back to default 3-level checkpointing
52    o Modifications to enable scripted COMMON to MODULE conversion
53      * verification/OpenAD/code/ has necessary scripts and description;
54      * converts, compiles and runs successfully;
55    
56    checkpoint57p_post
57    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
58    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
59      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
60    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
61    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
62      (was already the case for dissipation with mom_vecinv,
63       and also the case for grad.PhiHyd when staggered-timeStep)
64      This will allow to put dissipation out-off the AB time-stepping.
65     Unfortunately, affects truncation error. Update output of exp. that "fails"
66      (cg2d matching number) and leave the others for later: front_relax(10),
67      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
68      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
69    
70    checkpoint57o_post
71    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
72      (2) its ready to be documented during the 20050801 DocFest
73    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
74      for ideal_2D_oce and lab_sea on linux_ia32_g77
75    o set to #undef CTRL_SET_OLD_MAXCVARS_30
76      in global1x1_tot/code_seaice_adj to access indices 32, 33
77      (worth another tag)
78    
79    checkpoint57n_post
80    o adding precip control xx_precip 32
81    o adding swflux control xx_swflux 33
82    o Replacing 10 forcing penalty cost routines by 1 generic.
83    o Implementing partitioning in time-mean and variable adjustment
84      for atmos. state.
85    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
86    o in natl_box_adjoint:
87      * updated exp 1 to 10
88        (but does not have time-mean vs. variable split results yet)
89    o updated global1x1/*_seaice_adj/
90      to incorporate latest changes
91    o enable useSingleCpuIO for mdsio vector routines
92      (applies in particular to tapelev I/O)
93    o removed inefficient K-loop in all active_file*control*.F
94    
95    checkpoint57m_post
96    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
97      and advect_cs (use EXCH-2 and standard cs-32 grid files).
98    o pkg/exch2: filling of face-corner halo regions is optional
99      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
100    
101    checkpoint57l_post
102     tag before updating tutorials (pre-release-2)
103    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
104       for output and interpolation of input fields onto model grid)
105    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
106       Affects results of exp. rotating_tank ; update output.txt.
107    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
108          and taking the square quantity and/or using a fraction-weight field.
109    o fix aim_diagnostics_init.F mate numbers.
110    o add mnc output capability to diagnostics/diagstat and update
111      our cvsignore files for the ACSII output generated
112    
113    checkpoint57k_post
114    o lab_sea now uses diagnostics package and provides a suite of
115      new EXF diagnostics output.
116    
117    checkpoint57j_post
118    o exf
119      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
120        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
121        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
122      * extended diagnostics output
123        - now includes all EXF variables
124        - hs, hl moved to common block
125        - separate S/R for diagnostics, called after ctrl vector is added
126        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
127        - EXFqnet contains true Qnet (i.e. includes qsw)
128      * updated verif. lab_sea, global_with_exf
129      * Rearranging hflux (exf_mapfields -> exf_getforcing)
130        to ensure that diagnostics sees a true EXFqnet
131    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
132    o diagnostics pkg: change pointers so that 1 diagnostic can be used
133      several times with different frequencies.
134    o mnc-ify the thsice package as requested by Daniel Enderton
135      - the monitor--MNC output needs work
136      - many attributes need to be added (most are currently blank)
137    o mnc-ify theaim_v23 package as requested by Daniel Enderton
138      - many attributes need to be added (most are currently blank)
139    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
140    o add Sadourny like discretization to the 4th.O vorticity advection scheme
141    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
142      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
143         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
144    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
145     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
146    
147    checkpoint57i_post
148    o Diagnostics package was changed: diagnostic allocation is now deactivated
149      by setting an empty file name in the namelist (used to be by setting 0 frequency)
150    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
151      add 1rst Order upwind vertical Shear.
152    o add a quick fix for A/B checkpointing in OFFLINE mode
153    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
154      end-run around the C/Fortran linking horror in eesup/src/timers.F
155    o added pkg/runclock: allows user to terminate run based on wall clock
156    o added non-hydrostatic scaling parameter: nh_am2
157    o pkg/my82: futile attempt to make results compiler-independent by adding
158      some "_d 0", etc. no effect.
159    o for mnc output, fill the 'T' coordinate var with myTime and create a
160      separate 'iter' variable for iteration count
161    o pkg/diagnostics:
162      add new capability: output of Global/Regional & per-level statistics ;
163      tested against monitor output (including land & thSIce) on various exp.
164    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
165    
166    checkpoint57h_done
167      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
168      data.diagnostics, data.gchem, data.ptracers) is done.
169    
170    o pkg/diagnostics: prepare for Global/Regional statistics.
171      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
172    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
173      and rename it: DIFFERENT_MULTIPLE
174    
175    checkpoint57h_post
176    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
177    o pkg/diagnostics: change output frequency, now in seconds (instead
178      of Nb of iterations). This requires to change data.diagnostics.
179    checkpoint57h_pre
180    
181    o in mnc, let the user create the output dir if both mnc_outdir_date
182      and mnc_outdir_num are false
183    o add fflags() to pkg/diagnostics which allows one to specify, on a
184      per-file basis, the file precision [default behavior is unchanged]
185    o added diagnostics to pkg/kpp, including computation of mixed layer
186      depth based on a temperature/density criterion
187    o updated verification/natl_box to test the new pkg/kpp diagnostics
188    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
189    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
190    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
191      not mnc -- this mistake was found by JMC and is now corrected
192    
193    checkpoint57g_post
194    o add Adams-Bashforth 3rd Order time stepping:
195      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
196      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
197    checkpoint57g_pre
198    
199    o make lambda[Theta,Salt]ClimRelax spatially varying
200      (default remains spatially uniform constant based on tau)
201    o added new control variables
202      * init. uVel, vVel, etanN
203      * lambda[Theta,Salt]ClimRelax
204    o separate masks used for ctrl_pack/unpack 'from write_grid' output
205      (suggested by G. Forget)
206    
207    checkpoint57f_post
208    o add parameter "baseTime" = model base time = time at iteration zero
209      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
210      account for baseTime shift
211    o move Coriolis arrays from PARAMS.h to GRID.h
212    checkpoint57f_pre
213    
214    o mnc-ifying the seaice package
215    o introduced an alternative length scale calculation for use in the limiting
216      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
217    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
218    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
219      as well as grad(vort3).  Made it compatible with both approximate form
220      for the cubed sphere and full form of these gradients.  Added flag
221      useFullLeith to select between approximate and full form.  
222    o add "d0" in getcon.F to reduce differences between compilers/platforms
223      update output.txt of exp. fizhi-gridalt-hs
224    o change port_rand funtion to allow to set the seed.
225    o fix obscure MNC bug involving conversion between reals and integers
226      - it caused no problems with certain (eg. gcc, ifc) compilers but the
227        new version is now more standards-compliant
228    o adjoint-related modifications
229      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
230      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
231      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
232    
233    checkpoint57e_post
234    o Adding eddy stress controls a la Ferreira et al.
235    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
236    
237    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
238      update output.txt of exp. fizhi-gridalt-hs
239    o add more "Z" dimensions and associated coordinate vars to MNC
240    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
241    o parameter calendarDumps: when set, approximate months (30-31 days) and years
242      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
243      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
244      months and years.  Requires pkg/cal.
245    o diagnostics: add pickup functionality
246      - off by default for backwards compatibility
247      - current version only uses MDSIO -- MNC will be added
248    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
249    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
250    
251    checkpoint57d_post
252    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
253    o modify verification/ideal_2D_oce so that it tests the creation of mnc
254      output from the diagnostics package
255    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
256    o make genmake2 more portable by using ".$FS" instead of ".f" for more
257      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
258    o add coordinate variables to the MNC output from the diagnostics package
259    o change MNC-flags default value: true when useMNC=TRUE
260    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
261      the ability (off by default) to read the grid information using MNC
262    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
263    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
264    o do snap-shot diagnostics at the middle of the time-interval (instead of
265      at the end).
266    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
267      new test for AIM with thSIce + slab-ocean
268    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
269    o move state variable diagnostics to the beginning of the time step ;
270      (note: still needs some work specially for snap-shot diagnostics)
271      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
272    
273    checkpoint57c_post
274    o Change testing option (-ieee) to get closer agreement between g77 & ifort
275    o generate new output.txt files on faulks with g77 & the new -ieee option
276    checkpoint57c_pre
277    
278    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
279      update output.txt of exp. global_ocean.90x40x15
280    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
281      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
282    o add saltFlux(+File) forcing capability with periodicExternalForcing
283    o allow to use pkg diagnostics for GM-Redi & ThSIce output
284    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
285    o improvements for the MNC output from DIAGNOSTICS:
286      - correct handling of the unlimitied dimension
287      - all dims now have associated coordinate variables
288      - variables located at U, V, and Corner ("Z") points are now written
289        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
290        *all* data points are output
291    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
292    o added pkg/seaice/seaice_monitor.F
293    o mdsio_readfield.F can now read files visible only to master MPI process.
294    o pkg/seaice: some test code for ice-modified ocean stress
295    o exf_getffields interpolation defaults to bilinear for all scalar forcing
296      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
297      spurious negative numbers for precipitation and humidity.  Will cause
298      some small numerical differences for integrations using pkg/exf/exf_interp.F.
299    o pkg/ctrl/
300      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
301        May be enabled via doPackDiag
302      *  introduce z-scaling of
303         + gradient (doZscalePack) and
304         + control (doZscaleUnpack)
305    o pkg/mdsio/
306      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
307      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
308    
309    checkpoint57b_post
310    o simplify options in diagnostics_fill arguments (remove weird combinations)
311    o fix MNC coordinate variables so that they now contain per-face index
312      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
313      general, EXCH2 grids are only aligned to a "local" coordinate system
314    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
315    o Implement instantaneous output within pkg diagnostics:
316      setting a negative frequency in data.diagnostics produces
317     "snap-shot" output (as opposed to time-average if freq > 0)
318    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
319      NOTE: change ptracer diagnostics name: use 2 characters to work with
320            more than 9 tracers. Add also diagnostics of advect & diffus flux.
321    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
322      becomes the coordinate variable for the 'T' dimension
323    o add CF-style coordinate variables to MNC
324      - just a first cut:  numbers are meaningless on the cubesphere and
325        missing along the T axis but otherwise it works!
326    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
327    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
328    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
329      this is based directly on what the model compute, so that the content of
330      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
331    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
332    o clean up build options files for SunOS, in particular
333      - remove -traditional from xmakedepend
334      - change -xarch=v9 to -xarch=native for f77
335      - restore use of make (not gmake)
336      - add CC=gcc if using g77
337    o changes per discussion of AM, JMC, & EH3 today:
338      - move redundant "grid" variables out of "state" -- in preparation of
339        creating proper CF-style coordinate variables and in recognition
340        that any/all grid variables can be easily copied (eg. w/NCO) from
341        the grid files into any of the other NetCDF files
342      - *always* output grid variables with MDSIO (this will eventually be
343        changed)
344      - output MNC grid file if useMNC is true
345    o every instance of _END_MASTER() has been found and replaced with
346      _END_MASTER( myThid ) in order to satisfy certain picky Sun
347      preprocessors
348    o re-arrange diagnostics pkg initialisation:
349     - allow each package to extend the available diagnostics list
350     - add some checking and fix small problems (multi-threaded, ...)
351     - new S/R diagnostics_fill (replace fill_diagnostics):
352       look through the short list of active diag. (instead of the long list)
353       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
354    
355    checkpoint57a_post
356    o this set of changes restores TAMC compatibility
357      tested for global_ocean.90x40x15 adjoint on trough
358      (what a pain)
359    
360    checkpoint57a_pre
361    o some modifs in tools/build_options for sunos
362    o call ctrl_pack for ctrl at end for optimcycle=0
363    
364    checkpoint57
365    o add horizontal bi-harmonic viscosity for vertical velocity
366      - new parameter viscA4W (defaults to viscA4)
367      - affects only non-hydrostatic code
368      - to be done: no-slip lateral boundary conditions
369    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
370    o implement Implicit Vertical advection for pTracers
371    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
372      (implemented also for implicit vertical diffusion & advection)
373    o OBCS: extend application of tracer open boundary conditions
374      to a strip beyond the boundary of width Olx/Oly
375    o add call monitor to TAF set of required calls (flow directives)
376      and include in natl_box_adjoint
377    o untangle a few ifdefs related to cost, ctrl, autodiff
378      untangel a few ALLOW_ECCO_OPTIMIZATION
379    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
380      (theta2, salt2 in ecco_cost_weights)
381    
382    checkpoint56c_post
383    o OBCS as control variables
384      - update ctrl_ad_diff.list, obcs_ad_diff.list
385      - remove balance of obcs controls from default
386      - fix index bug nobcs in ctrl_init
387      - fix dummy fields filen in ctrl_pack
388      - add dummy weights for obcs
389    o lsopt: comment out fort.94 output
390    o optim:
391      - remove unnecessary header files
392      - adjusted namelists
393      - add xerbla.F to Makefile
394    o exf:
395      - multiple modifications of exf_check_range
396      - unit change in exf_init_runoff from [m/year] to [m/s]
397    o mdsio:
398      - i/o-vector change debugLevel from debLevA to debLevB
399    
400    checkpoint56b_post
401    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
402      is called from DO_THE_MODEL_IO
403      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
404      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
405      - clean up PTRACERS_WRITE_TIMEAVE a little
406    o add another verification experiment that tests both the cfc-pkg and
407      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
408      reactive tendencies treated inline with regular timestepping
409    o testreport previously did a lousy job of comparing small numbers, so
410      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
411      implemented in the little c-progam tmp_cmpnum.c which is embedded in
412      testreport.
413    o ptracers_monitor: bug fix for MPI
414    
415    checkpoint56a_post
416    o GCHEM: finish reorganizating the package
417      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
418        (introduces another 3D-array for each passive tracer, but only if
419        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
420        gchemTendency is not needed because the timestep is done separately)
421      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
422      - GCHEM is now---more or less cleanly---separate from PTRACERS
423      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
424        so clear to me how that should be done in a general way.
425    o CFC: improve formatting of output in CFC_ATMOS
426    o PTRACERS:
427      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
428        that ALL experiments with ptracers enable can be checked. This makes
429        GCHEM_MONITOR obsolete.
430      - include a runtime parameter PTRACERS_monitorFreq that defaults to
431        monitorFreq
432      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
433    o add PTRACERS (PTR0[1-5]) to testreport output
434    o exf_check_range:
435      * default changed to .TRUE.
436      * will check values for niter0 if debLevA, every timestep if debLevB
437      * STOP in exf_check_range if 'out of range'
438      * range chosen generous to allow for potential extema
439      TBD: a version with stricter range
440           permitted range would be runtime parameters
441    o GMredi:
442      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
443      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
444      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
445    o GCHEM:
446      - move call to GCHEM_FORCING_SEP, so that it is now called before
447        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
448      - introduced a useGCHEM runtime flag and applied it everywhere.
449      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
450        this flag is now only visible within GCHEM-pkg routines.
451      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
452        be replaced by a 3D array that is computed before thermodynamics; for
453        this, the tracer ID iTracer had to be included into the parameter list
454        of ptracers_forcing
455      - set up forward_step to call gchem_forcing, that will replace
456        gchem_forcing_int in ptracers_forcing
457      - cleaning up
458    o small cleaning of exch2: remove files that are also in eesupp/src
459    
460    checkpoint56
461    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
462    o mnc: cleanup "full" files--fixes out-of-memory problem
463    o ECCO-GODAE
464      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
465      * fully merged and updated from SIO code
466        windstress sign change affects
467        - exf_inscal_[u/v]stress
468        - sign of xx_tau[u/v] adjustments
469        - signs in cost_scat
470      * ctrl_get_gen: avoid update of tau[u/v] for first few days
471      * natl_box_adjoint updated and compressed
472      * 2-level checkpoint switch added
473        (tested in EXP. 1 of natl_box_adjoint)
474      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
475    o SVD
476      * first complete, non-hacked version for SVD calculations
477      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
478        performed via direct access files admtlm_vector.it????
479        (via ctrl_[un]pack)
480      * optimcycle is used for ARPACK iteration counter
481        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
482      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
483        and add linear transforms where necessary
484      * controls are initial/final SST, SSS (can be extended; need to check
485        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
486    o mdsio: filename info to both stderr, stdout
487    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
488      from sign change
489    
490    checkpoint55j_post
491    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
492      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
493    o add consistent build directories and .cvsignore files to verification
494    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
495    o make all subroutines 30 or less characters in length for certain older
496      compilers to work (a thorough search only turns up two routines in
497      pkg/ptracers)
498    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
499      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
500    
501    checkpoint55i_post
502    o change arrays for total vertical diffusivity (2.D if explicit,
503      3.D if implicit) ; each ptracer uses its own background value.
504    o added mnc/NetCDF output capability to ocn_compon_interf
505      - added bits to verification/cpl_aim+ocn so that it can run on
506        ITRDA and other clusters without the mpirun "-wd" option
507    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
508      configuration
509    o give MNC the ability to create additional files rather than
510      exceeding a specified file size limit "MNC_MAX_FILESIZE"
511      - the default is just less than 2GB which is a practical limit
512        on many systems
513    o Compute the non-local term using either KPP vertical diffusivity (=default)
514       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
515    
516    checkpoint55h_post
517    o add verification test "vermix"
518    o remove all the *_ioinc flags and replace with the single global
519      outputTypesInclusive flag
520    o allow to set a vertical profile of vertical diffusivity for T & S
521    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
522    o useMNC moved from data.mnc to data.pkg
523    
524    checkpoint55g_post
525    o Renaming carbon AD experiments to comply with testreport conventions
526    o Updating adjoint of Held-Suarez hs94.1x64x5
527    o Fixing directives for non-ECCO forward_step, after ECCO directives
528      have been fixed to avoid recomp. of do_oceanic_phys
529      Works well for global_ocean.90x40x15,
530      but recomp. issue remains for carbon
531    o Updating adjoint output for natl_box_adjoint after
532      pkg/ecco has been modified (see taga c55d_post)
533    
534    checkpoint55f_post
535    o rename to timeave_init_fixed
536    
537    checkpoint55e_post
538    o some delicate re-shuffle of store directives to avoid one
539      extra call of do_oceanic_physics
540      affects ecco_the_main_loop.F, do_oceanic_physics.F
541      checkpoint_lev1_directives.h
542    o NB: this may break global_ocean adjoint temporarily,
543      but it is clear how to fix it. Will do later, need this now.
544    
545    checkpoint55d_post
546    o ECCO specific cost function terms (up-to-date with 1x1 runs)
547    o ecco_cost_weights is modified to 1x1 runs
548    o modifs to allow observations to be read in as
549      single file or yearly files
550    o enable to read exf forcing fields as either
551      single file or yearly files (flag useExfYearlyFields)
552    checkpoint55d_pre
553    
554    o switch between 2-level and 3-level checkpointing
555    o add ability of MNC to write local and "partial" (eg. 2D slices where
556      the full 3D field is never actually stored) arrays to NetCDF files
557      with the correct (that is, the complete multi-dimensional) set of
558      array indicies
559      - used in mom_vecinv() to write the diagFreq output
560      - tested (demonstrated) in verification/aim.5l_cs
561    o further mnc-ification
562      - add verification/lab_sea to the list with mnc setups
563      - fix undefined mnc v-names in cd_code
564      - add kpp to mnc output (both snapshot and timeave)
565    o non-hydrostatic code
566      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
567        in calc_gw.F
568      - defaults to viscAh
569      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
570        friction or Leith) in non-hydrostatic mode, as long as there is
571        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
572    o pkg/cost
573      extend simple cost functions to treat time mean quantities
574      (T,U,V) via cost_accumulate_state from cost_tile
575    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
576        be 2 times larger than the minimum size the advection scheme requires.
577        now get a perfect conservation of salt in advect_cs test-exp (updated)
578    o GGL90 (Gaspar's TKE mixed layer)
579      - add horizontal diffusion of TKE, requires exchanges in
580        do_fields_blocking_exchanges, horizontal diffusivity is zero by
581        default. In OPA there is no horizontal diffusion of TKE but the
582        mixing coefficients are computed from a horizontal average of TKE of
583        6 points or so. I think that diffusion has a little more physical
584        justification.
585      - clean up ggl90_calc in the hope of reducing memory usage (this hope
586        was in vain)
587      - mask tke-variable in ggl90_init
588    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
589    o fix biharmonic diffusion on CS-grid.
590    o more obcs stuff
591      - added obcs_external_fields_load as an alternative to the EXF-pkg option
592        for reading boundary values. This routine is called from
593        obcs_prescribe_read
594      - updated obcs_check
595      - changed sponge layer relaxation parameter units for days to seconds
596      - turned off sponge layer by default
597      - changed argument list of OBCS_CALC to myTime+deltaTclock
598      - fixed about 35 bugs in obcs_external_fields_load
599    
600    checkpoint55c_post
601    o obcs stuff
602      - new runtime flags useOBCSprescribe, useOBCSbalance
603      - re-arranged obcs_calc
604      - moved exf_getobcs to obcs_prescibe_read
605        obcs_prescibe_read is called after ORLANSKI stuff
606        and independent of it (executable can contain all).
607      - updated obcs_check
608      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
609        These may be necessary only if tangential velocities are
610        prescribed at OB, not sure, needs testing.
611    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
612      which simplifies the calls and passes the ifc check-bounds test
613    
614    checkpoint55b_post
615    o add a 2D scalar, Z location, exchange_2 routine.
616    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
617      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
618      affects advect_cs results (for the wrong reason): update output.txt
619    o use a more standard discretization for biharmonic viscosity ;
620     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
621      affects results of dome set-up: update output.txt
622    o fix gad_advection.F (CubedSphere part), back to version 1.23
623    o fix bug in mom_vi_del2uv.F (CubedSphere part).
624    
625    checkpoint55a_post
626    o merged code to
627      * prescribe/read time-dependent open boundaries
628        (works in conjunction with exf, cal)
629      * sponge layer code for open boundaries
630      * each boundary N/S/E/W now has its own CPP option
631        (healthy for the adjoint)
632    
633    checkpoint55
634    o up-to-date adjoint of previous breaks
635      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
636      - global_ocean_ebm: adjoint still needs fix (TLM ok)
637      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
638      - carbon: * remove tr1-related adjoint verification
639                * add ptracer as control variable
640    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
641      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
642    
643    checkpoint54f_post
644    o in verification/carbin/ remove experiment related to
645      ALLOW_PASSIVE_TRACER (array tr1 etc)
646      code_ad/ input_ad/ results_ad
647    
648    o add two new packages
649      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
650        + subject to optimization (memory)
651      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
652        + subject to reordering (many GOTOs in the original code)
653        + so far opps is called for every (i,j) point, and then operates in
654          the vertical; one may want to reorder the scheme in order operate in
655          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
656          fields)
657    o overhaul of IO so that we now have flags for MDSIO and/or MNC
658      - all verification tests compile and run with linux_ia32_g77
659      - defaults are compatible with current input files--nothing
660        should change if you were not previously using MNC
661      - MNC output has been added in numerous places (eg. timeave)
662        but there are still a few writes not yet do-able with MNC
663        (this is in progress)
664      - flags now allow for either/or/both use of MDSIO and MNC and
665        documentation will soon follow
666      - numerous small formatting cleanups for ProTeX
667    o add version info (via BUILD_INFO.h) to MNC and stdout
668    
669    checkpoint54e_post
670    o add two new packages
671      - pp81 (Packanowski and Philander, 1981), Richardson number and
672        stratification dependent mixing
673      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
674      - these scheme operate in a similar manner as KPP (without ghat, of
675        course), however there is only one diffusivity that is used for both
676        temperature and salinity (and passive tracers)ç
677    o add offline package
678    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
679      provided by Stephanie Dutkiewicz
680    o genmake2: add ability to search for C compilers and cleanup test output
681      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
682    
683    checkpoint54d_post
684    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
685    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
686      leading to additional shift by 5 days each year of integration
687       (i.e. leading to considerable offset over the years)
688    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
689    o start with no AB and no initial filtering (staggerTimeStep):
690      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
691    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
692      (external loading & cpl import/export stay in forward_step.F)
693    o update coupling interface to work with new staggerTimeStep
694    o change MDSIO ptracers_pickup.
695    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
696    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
697    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
698    
699    checkpoint54c_post
700    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
701      this affects (truncation error) output.txt of test-exp:
702       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
703    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
704    o change Qnet to always be the net heat flux, (+upward).
705      affects (truncation error) output of natl_box exp.: updated
706    o define the max number of passive tracers in PTRACERS_SIZE.h
707    o start to test mnc routinely in exp0
708    o add sea-ice loading (sIceLoad) as a new forcing field.
709    
710    checkpoint54b_post
711    o add testreport "-j JOBS" option for parallel builds (tested and pretty
712       impressive on Altix and Opteron systems)
713    o diagnostics can now write NetCDF files through the mnc package
714    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
715    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
716    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
717      affects (truncation error) output of lab_sea & natl_box exp.: updated
718    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
719    
720    checkpoint54a_post
721    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
722    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
723    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
724    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
725      + internal_wave (shift in writing cg2d_ini_res)
726    checkpoint54a_pre
727    
728    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
729      - modified verification/lab_sea and natl_box_adjoint accordingly
730    
731    checkpoint54
732    checkpoint53g_post
733    o prepare splitting of thermodynamics: store convect.counter in common block
734    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
735      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
736    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
737    o new parameter "nShapS": allow to treat differently S from T (nShapT)
738    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
739    o restore adjointability
740    
741    checkpoint53f_post
742    o modifications that affect AIM experiment results (update output.txt):
743      - no advection of S at top interface Nr (pkg/generic_advdiff)
744      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
745    o AIM pkg:
746      - include stability function into surf.Flux derivative relative to Tsurf
747      - calculate clear-sky radiation & surface temp. change (for diagnostics)
748    
749    checkpoint53e_post
750    o merged cylindrical coord configuration
751    o added rotating_tank experiment
752    checkpoint53e_pre
753    
754    checkpoint53d_post
755    o faulks upgraded: re-generate output.txt that have changed:
756       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
757    o Added Bryan and Lewis, 1979, vertical diffusivity profile
758    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
759    o added Sadourny discretization of Coriolis
760      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
761      - re-enabled use of omega3 (useAbsVorticity)
762    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
763      vector-invariant equations
764      - note: does *NOT* yet use same variable visc. for no-slip BC's.
765    o recoded the lateral boundary conditions for non-hydrostatic w, this time
766      hopefully without new bugs
767      - still to do: biharmonic friction for non-hydrostatic w
768    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
769    o regenerated output for global_ocean_ebm (using -ieee)
770    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
771      of mom_common/
772      - simple re-arrangement of instructions within computing loop
773    checkpoint53d_pre
774    
775    checkpoint53c_post
776    o new version of coupler for AIM+thSIce and Ocean models
777     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
778     - land: change Evaporation of snow
779     - aim with thSIce: fix bug in snow-precip.
780    o changes to calc_gw.F
781     - bug fix for w^2 term near the bottom boundary
782     - (hopefully) improve the lateral slip boundary condtions for use with
783        partial/looped cells
784      - because the bug fix changes two verification experiments anyway (exp5
785        and plume on slope), change the lateral boundary condition from half slip
786        to the value of no_slip_sides
787    o ebm package wasnt quite up to the parallel task. Fixed that.
788    o Adjoint of EBM package + verification
789      * TLM OK
790      * ADM not sufficient accuracy yet (needs further testing)
791    
792    checkpoint53b_post
793    o Commiting new energy balance model to repository
794      * package is pkg/ebm
795      * verif. is verification/global_ocean_ebm
796      * references are in ebm_driver.F
797    C      * X. Wang, P. Stone and J. Marotzke, 1999:
798    C        Global thermohaline circulation. Part I:
799    C        Sensitivity to atmospheric moisture transport.
800    C        J. Climate 12(1), 71-82
801    C      * X. Wang, P. Stone and J. Marotzke, 1999:
802    C        Global thermohaline circulation. Part II:
803    C        Sensitivity with interactive transport.
804    C        J. Climate 12(1), 83-91
805    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
806    C        Destabilization of the thermohaline circulation
807    C        by atmospheric eddy transports.
808    C        J. Climate 7(12), 1870-1882
809    o Will need long integration testing.
810    checkpoint53b_pre
811    
812    o created pkg/mom_common in preparation for variable viscosity code
813    o renamed and split ini_mnc_io
814    o pkg/land: only liquid water can diffuse or run-off
815    o AIM using land: soil wetness availability account for snow
816    o added printMapIncludesZeros to EEPARMS namelist
817    
818    checkpoint53a_post
819    o restore TAMC compatiility for exf_constants.h
820      (no usage of _d in .h)
821    o Additional storing in KPP in an attempt to fix
822      TAMC problem with adjoint of KPP code.
823      (no success...)
824      Identical code works fine with TAF.
825    o Fixed verification/natl_box_adjoint experiments.
826      Initial conditions for Experiments 4 and 5 are now
827      set to "SEAICE_initialHEFF=0", which is more reasonable,
828      and hence gives results closer to that of Experiment 2.
829      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
830    
831    checkpoint53
832    o stable checkpoint with up to date adjoint
833      TLM tests only run for 1st grdchk at the moment. Its unclear if
834      this is a code problem or a problem with resetting code for g_
835      variables that is being autogenerated wrong.
836      Otherwise:
837       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
838       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
839         are both still in chaos following their security messes.
840    
841    checkpoint52n_post
842    o various build (mostly genmake2) changes including:
843      - ability to build/run more easily within Cygwin and MacOS X
844      - more complicated Makefiles with a stronger dependence on Gnu Make
845    o pkg/seaice modifications
846      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
847        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
848        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
849      - changed proxy for geostrophic velocity and updated
850        verification/lab_sea/results/* accordingly
851      - removed ADI dynamic solver from pkg/seaice
852      - replaced all occurrences of 1/CSTICE or 1/CSUICE
853        they caused a segmentation fault under certain circumstances
854      - removed unused field WATR
855    o bug fix in exf-package:
856      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
857         now reflect that.
858    o small fixes in the cal-package:
859      - set reference date to first of January for the 'model'-calendar
860      - failing of cal_CheckDate in cal_FullDate now actually results in a
861        warning
862    o small modifications in exf-package to increase flexibility:
863      - change climtempfreeze from a constant to a runtime parameter that
864        is specified in data.exf_clim (default = -1.9)
865      - introduce runtime parameter windstressmax (default = 2.0) that is
866        specified in data.exf
867    o fix in pkg/thsice:
868      - update Evap (Tsf changes) to be consistent with Latent heat flux
869      - maintain snow precipitation unchanged (even if Tsf >=0).
870     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
871    
872    checkpoint52m_post
873    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
874      this does not change any of the results, because myIter=0 in swfrac always
875      lead to jwtype=2 (the default anyway), but the call makes little sense
876      as a default
877    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
878    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
879      atmospheric model (AIM) to use it ; add a "slab ocean" component.
880    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
881    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
882    o extending useSingleCpuIO option to work with new exch2 I/O format
883      - old-style, missing-tile I/O is still accessible by defining CPP
884        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
885    o monitor package can write to NetCDF files and/or STDOUT
886    o fix re-definition bug in MNC_GRID_INIT_ALL()
887    o doc/api_reference added
888      - a framework for building an API Reference Manual using all
889        the "protex" comments embedded in the code
890      - see pkg/generic_advdiff, pkg/mnc for examples
891    o MNC:
892      - make myThid the last argument for all subroutines
893      - new default for the grid files: NO halos
894      - add useMNC and other run-time flags
895      - separate per-file-group handling of the unlimited dimension
896      - early initialization of MNC w/ flags read at the eeboot stage
897        and lookup tables set in initialize_fixed
898      - write all MNC output to a freshly-created directory
899    o thermodynamics sea-ice (thsice) is now tested with testreport.
900    o test exp. advect_cs: use the standard cs32 grid ; update output.
901    o Added functionality to grdchk:
902      pick global i,j,k position (or nearest wet) where to perform check.
903    
904    checkpoint52l_post
905    o new land formulation:
906      a) use ground enthalpy as prognostic variable to ensure exact
907         energy conservation.
908      b) account for water temperature and for latent heat of freezing
909         in all processes (rain, run-off, ground storage)
910      c) compute surface and ground temperature implicitly.
911    o aim_v23 modification for new land model:
912      a) Treat separately land / ocean / sea-ice surface fluxes
913         to allow implicit computation of land & sea-ice surface temp.
914      b) add snow precipitation.
915    checkpoint52l_pre
916    
917    o fix problem (when 1 tile is empty) in min/max monitor.
918    o fix bug in timeAve (u,vZetatave in common block)
919    o no restoring terms under ice for pkg/seaice
920    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
921    o bug fix for pkg/seaice pickups
922    o change MNC call locations and add coordinate attributes
923    o mask vorticity at the corner ; affects global_ocean.cs output
924    o fix ini_curvilinear_grid ; test CS experiments with mpi
925    o aim.5l_cs: modify sea-ice fraction input file ; update output
926    o exf: Adding simple range check routine for exf fields after read
927    
928    checkpoint52k_post
929    o removed top-level directory "diags"
930      - we migrated these functions to pkg/timeave a long time ago
931    o fixed bug introduced in pkg/monitor
932    o accuracy ctrlprec = 32 insuffient for gradient checks using
933      averaged fields (I/O via cost_averages)
934      -> use ctrl.h in active_file*.F to control I/O precision.
935    o paramter list of CALL ADTHE_MAIN_LOOP
936    o added initial do_the_model_io to ecco
937    o set all ...Freq to zero after cost_final
938      taveFreq, dumpFreq, pChkptFreq
939    o MAIN and ECCO differentiability restored
940    
941    checkpoint52j_post
942    o fix nchklev in tamc.h for global_ocean...
943    o Bringing flow and store directives up-to-date
944    o Really weird thing!
945      call do_the_model_io from the_main_loop with parameters
946      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
947      TAF places a faulty re-call of initialise_varia
948      after cost_final call which should not be there!
949    checkpoint52j_pre
950    
951    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
952      error messages
953    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
954    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
955      debug output
956    o modfied mdsio_writefield.F to handle non-global files under exch2
957    o update AIM Cubed-Sphere exp (aim.5l_cs):
958      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
959    o update AIM Equatorial Channel exp:
960      use standard aim_v23 pkg and change the SST fields to be more realistic.
961    o globalFile now works with exch2
962    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
963      mon_vort3.F to make exch2 friendly with >1 tile per cube face
964    o limit timeave output for hi-res integrations
965    
966    checkpoint52i_post
967    o removed CPP_EEOPTIONS.h from verification/*/code
968    o updated the tiling for global_ocean_pressure
969    checkpoint52i_pre
970    
971    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
972      the old pkg/aim).
973    
974    checkpoint52h_pre
975    o shortened offending lines in exch2_send_rx?.template
976    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
977    o genmake2: add build & execute test for NetCDF code
978    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
979      old grid files, moved CPP_EEMACROS.h to pkg/exch2
980    o added useSingleCPUIO flag to monitor.F and mon_out.F
981    o added temporary hack for sea-ice dynamics on the cube:
982      metric terms are ignored and it is assumed that
983      there is no sea-ice on cube faces 1, 2, 4, and 5.
984    
985    checkpoint52f_post
986    o added exch2 cube routines to pkg/exch2
987    o modified hs94.cs-32x32x5 to use it
988    o added new grid files to hs94.cs-32x32x5
989    checkpoint52f_pre
990    
991    checkpoint52e_post
992    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
993      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
994    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
995      to work with implicit vertical advection and AB ;
996    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
997    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
998     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
999    checkpoint52e_pre
1000    
1001    o fix bug in impldiff when Nr=1 or Nr=2.
1002    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1003    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1004    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1005      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1006    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1007    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1008    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1009    
1010    checkpoint52d_post
1011    o re-tiled many expts to allow comparison in multi-processor mode
1012      - updated output accordingly
1013      - changed hs94.128x64x5 to use intial T from file rather than use the
1014        random number generator
1015    o add infrastructure in model routines for fizhi and gridalt packages
1016    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
1017    o changes to permit hi-res, cubed-sphere, configuration
1018      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
1019      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1020      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1021        of surface winds for the cube
1022      (A verification experiment, based on global_ocean.cs32x15, but with
1023       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1024       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1025       complete with example surface forcing files and matlab scripts to look
1026       at the output and compare it with that of global_ocean.cs32x15.)
1027    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1028       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1029       to conform to the common rule.
1030    o check-in the first version of the coupler + interfaces for multi-components
1031       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1032       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1033       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1034       - ocean and atmos. share the same horizontal grid (no interpolation).
1035       - exchanges between component and coupler is done in forward_step
1036    o new verification experiment, cpl_aim+ocn:
1037       coupled ocean - AIM atmosphere on cs32 grid.
1038    
1039    checkpoint52d_pre
1040    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1041    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1042    
1043    checkpoint52c_post
1044    o Fixing OPTIONS files for use of exf:
1045      - ALLOW_ECCO not needed
1046      - ECCO_CPPOPTIONS.h should not be included from
1047        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1048        as has been the case in the past
1049      - All cal/exf related options are currently set in
1050        single header file. Should remain so until we
1051        agree on a consistent new policy.
1052    o Removed all CPP options for cal package.
1053      cal has no more CPP options.
1054    o modified STOREs in GAD_ADVECTION
1055    o corrected key comp. for passkey
1056    
1057    checkpoint52b_post
1058    o new version: "thsice" of thermodynamic sea-ice pkg:
1059     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1060     - modify fluxes but do not change theta directly;
1061     - light cleaning of bulk_force pkg (still needed with thsice).
1062     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1063       + output_thsice.txt to test thsice & bulk_force pkgs.
1064    o put back grid & coriolis monitor output.
1065    checkpoint52b_pre
1066    
1067    o call "do_the_model_io" at the beginning (=> dump initial state)
1068    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1069    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1070      (need info on NUMBER_OF_PTRACERS)
1071    o missing PTRACERS headers in some routines
1072    o default tamc.h in pkg/autodiff supposed to crash
1073      to ensure proper customization
1074    
1075    checkpoint52a_post
1076    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1077      - moved surfaceTendencyTice from pkg/seaice to main code
1078      - subroutine FREEZE_SURFACE now limits only surface temperature
1079        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1080        => new output.txt for global_ocean.cs32x15 & global_with_exf
1081      - keep the old version of FREEZE for backward compatibility;
1082        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1083      - corresponding modifs for TAF directives
1084    o added surface flux output variables to TIMEAVE_STATVARS
1085    o time-averaged output for pkg/ptracers
1086    o fix problem with ECCO-related divided adjoint
1087      snapshot file was missing some ad-variables,
1088      but no warning issued by TAF
1089    
1090    checkpoint52a_pre
1091    o some bug fixes for #undef REAL4_IS_SLOW
1092    
1093    checkpoint52 = ecco_c52_e35
1094    o after testing adjoints of checkpoint51u_post
1095    
1096    checkpoint51u_post
1097    o this is the post-merge tag of the ecco-branch
1098      (needs another clean checkout and re-testing)
1099    o various natl_box_adjoint configs and results
1100      but no input fields
1101    o obcs adjoint not yet merged!
1102    o adding ECCO global 1x1 and 2x2 degree configs
1103    o updated/extended some store directives for seaice
1104    o pkg/ecco now containes ecco-specific part of cost function
1105    o top level routines the_main_loop, forward_step
1106      supersede those in model/src/
1107      previous input data.cost now in data.ecco
1108      (new namelist ecco_cost_nml)
1109    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1110    
1111    checkpoint51t_post
1112    o this is the pre-merge tag of the ecco-branch
1113    
1114    checkpoint51s_post
1115    o cleanup: removed various obsolete #define-s
1116    o pkg/grdchk
1117      - renamed 'ph-grd 3' to 'grad-res'
1118      - merged from ecco-branch
1119        (remaining bug fixes for obcs gradient checks)
1120      - additional high-precision output for testreport
1121        (grep for 'precision_grdchk_result')
1122    
1123    checkpoint51r_post
1124    o cleaned up or removed CPP_OPTIONS.h files
1125    o updated results for some of the tests to reflect the new
1126      optfiles (-ieee: -O0 instead of -O3)
1127    
1128    checkpoint51q_post
1129    o cd_code:
1130      - moved cd_scheme.F -> cd_code_scheme.F
1131      - separate read_checkpoint from cd_code_ini_vars.F
1132      - separated cd_code part from write_checkpoint
1133      - updated AD_SOURCE, generated .flow
1134      - added CD_CODE_VARS.h to the_main_loop
1135      - Moving cd_code specific store dir.s to pkg/cd_code
1136    o ctrl package totally restructured
1137      - pack/unpack now optional and decoupled from
1138        xx_/adxx_ I/O
1139      - ctrl_pack/unpack cleaned
1140        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1141      - confined inclusion of AD_CONFIG.h to where necessary.
1142    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1143

1145    o create initial cd_code package
1146      - WARNING: the initialization of fields within packages
1147        is broken because INI_FIELDS (where READ_CHECKPOINT is
1148        called) is called *before* PACKAGES_INIT_VARIABLES.
1149        This seems to be backwards since
1150        1) its important to initially zero the entire field including
1151           the "halo" region
1152        2) zeroing needs to be done *before* reading pickup info
1153           and the pickup call might or might not happen in any
1154           particular run
1155      - this needs an overhaul for R2
1156    o cleanup verification/*/code/GMREDI_OPTIONS.h
1157    o cleanup testreport
1158    
1159    checkpoint51o_post
1160    o bringing AD-related verif's up to date with genmake2
1161      - carbon/
1162      - global_ocean.90x40x15/
1163      - hs.94.1x64x5/
1164      - (front_relax/ )
1165    o (more) consistent directory structure for AD-related verif.'s
1166    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1167    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1168    o bug fix in find_alpha.F for MDJWF:
1169      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1170        change rho -> rho-rhoConst
1171      - replace call find_rho to find_rhonum
1172    o initialisation of rFlx extended to full array (required by TAF)
1173      and shifted to thermodynamics
1174    o removed PTRACERS.h in ptracers routine
1175    o added surfacetendencyPtr to S/R parameter list pracers_forcing
1176    o Correcting initialisations for fVerU, fVerV.
1177    o helping TAF to recognize dependency on kUp for
1178      fVerU, fVerV
1179    o Replacing delZ by delR in pkg/ctrl/
1180    checkpoint51o_pre
1181    
1182    o undid all of cp51 pending some cleanups and discussion
1183    o added the [#include "AD_CONFIG.h"] statement to all files that need
1184       it for adjoint/tl #defines
1185     o re-worked the build logic in genmake2 to support AD_CONFIG.h
1186     o removed tools/genmake since it no longer works
1187    
1188    checkpoint51n_post
1189    o modifications to make FREEZE flux visible to pkg/kpp
1190      - moved surfaceTendencyTice from pkg/seaice to main code
1191      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1192      - subroutine FREEZE now limits only surface temperature
1193        (this means new output.txt for global_ocean.90x40x15,
1194         global_ocean.cs32x15, and global_with_exf)
1195    o added surface flux output variables to TIMEAVE_STATVARS
1196    
1197    checkpoint51n_pre
1198    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
1199    o added [#include "AD_CONFIG.h"] to all files that use the following
1200      defines:
1201      - ALLOW_ADJOINT_RUN
1202      - ALLOW_TANGENTLINEAR_RUN
1203      - ALLOW_ECCO_OPTIMIZATION
