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

797    o Will need long integration testing.
798    checkpoint53b_pre
799    
800    o created pkg/mom_common in preparation for variable viscosity code
801    o renamed and split ini_mnc_io
802    o pkg/land: only liquid water can diffuse or run-off
803    o AIM using land: soil wetness availability account for snow
804    o added printMapIncludesZeros to EEPARMS namelist
805    
806    checkpoint53a_post
807    o restore TAMC compatiility for exf_constants.h
808      (no usage of _d in .h)
809    o Additional storing in KPP in an attempt to fix
810      TAMC problem with adjoint of KPP code.
811      (no success...)
812      Identical code works fine with TAF.
813    o Fixed verification/natl_box_adjoint experiments.
814      Initial conditions for Experiments 4 and 5 are now
815      set to "SEAICE_initialHEFF=0", which is more reasonable,
816      and hence gives results closer to that of Experiment 2.
817      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
818    
819    checkpoint53
820    o stable checkpoint with up to date adjoint
821      TLM tests only run for 1st grdchk at the moment. Its unclear if
822      this is a code problem or a problem with resetting code for g_
823      variables that is being autogenerated wrong.
824      Otherwise:
825       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
826       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
827         are both still in chaos following their security messes.
828    
829    checkpoint52n_post
830    o various build (mostly genmake2) changes including:
831      - ability to build/run more easily within Cygwin and MacOS X
832      - more complicated Makefiles with a stronger dependence on Gnu Make
833    o pkg/seaice modifications
834      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
835        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
836        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
837      - changed proxy for geostrophic velocity and updated
838        verification/lab_sea/results/* accordingly
839      - removed ADI dynamic solver from pkg/seaice
840      - replaced all occurrences of 1/CSTICE or 1/CSUICE
841        they caused a segmentation fault under certain circumstances
842      - removed unused field WATR
843    o bug fix in exf-package:
844      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
845         now reflect that.
846    o small fixes in the cal-package:
847      - set reference date to first of January for the 'model'-calendar
848      - failing of cal_CheckDate in cal_FullDate now actually results in a
849        warning
850    o small modifications in exf-package to increase flexibility:
851      - change climtempfreeze from a constant to a runtime parameter that
852        is specified in data.exf_clim (default = -1.9)
853      - introduce runtime parameter windstressmax (default = 2.0) that is
854        specified in data.exf
855    o fix in pkg/thsice:
856      - update Evap (Tsf changes) to be consistent with Latent heat flux
857      - maintain snow precipitation unchanged (even if Tsf >=0).
858     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
859    
860    checkpoint52m_post
861    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
862      this does not change any of the results, because myIter=0 in swfrac always
863      lead to jwtype=2 (the default anyway), but the call makes little sense
864      as a default
865    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
866    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
867      atmospheric model (AIM) to use it ; add a "slab ocean" component.
868    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
869    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
870    o extending useSingleCpuIO option to work with new exch2 I/O format
871      - old-style, missing-tile I/O is still accessible by defining CPP
872        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
873    o monitor package can write to NetCDF files and/or STDOUT
874    o fix re-definition bug in MNC_GRID_INIT_ALL()
875    o doc/api_reference added
876      - a framework for building an API Reference Manual using all
877        the "protex" comments embedded in the code
878      - see pkg/generic_advdiff, pkg/mnc for examples
879    o MNC:
880      - make myThid the last argument for all subroutines
881      - new default for the grid files: NO halos
882      - add useMNC and other run-time flags
883      - separate per-file-group handling of the unlimited dimension
884      - early initialization of MNC w/ flags read at the eeboot stage
885        and lookup tables set in initialize_fixed
886      - write all MNC output to a freshly-created directory
887    o thermodynamics sea-ice (thsice) is now tested with testreport.
888    o test exp. advect_cs: use the standard cs32 grid ; update output.
889    o Added functionality to grdchk:
890      pick global i,j,k position (or nearest wet) where to perform check.
891    
892    checkpoint52l_post
893    o new land formulation:
894      a) use ground enthalpy as prognostic variable to ensure exact
895         energy conservation.
896      b) account for water temperature and for latent heat of freezing
897         in all processes (rain, run-off, ground storage)
898      c) compute surface and ground temperature implicitly.
899    o aim_v23 modification for new land model:
900      a) Treat separately land / ocean / sea-ice surface fluxes
901         to allow implicit computation of land & sea-ice surface temp.
902      b) add snow precipitation.
903    checkpoint52l_pre
904    
905    o fix problem (when 1 tile is empty) in min/max monitor.
906    o fix bug in timeAve (u,vZetatave in common block)
907    o no restoring terms under ice for pkg/seaice
908    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
909    o bug fix for pkg/seaice pickups
910    o change MNC call locations and add coordinate attributes
911    o mask vorticity at the corner ; affects global_ocean.cs output
912    o fix ini_curvilinear_grid ; test CS experiments with mpi
913    o aim.5l_cs: modify sea-ice fraction input file ; update output
914    o exf: Adding simple range check routine for exf fields after read
915    
916    checkpoint52k_post
917    o removed top-level directory "diags"
918      - we migrated these functions to pkg/timeave a long time ago
919    o fixed bug introduced in pkg/monitor
920    o accuracy ctrlprec = 32 insuffient for gradient checks using
921      averaged fields (I/O via cost_averages)
922      -> use ctrl.h in active_file*.F to control I/O precision.
923    o paramter list of CALL ADTHE_MAIN_LOOP
924    o added initial do_the_model_io to ecco
925    o set all ...Freq to zero after cost_final
926      taveFreq, dumpFreq, pChkptFreq
927    o MAIN and ECCO differentiability restored
928    
929    checkpoint52j_post
930    o fix nchklev in tamc.h for global_ocean...
931    o Bringing flow and store directives up-to-date
932    o Really weird thing!
933      call do_the_model_io from the_main_loop with parameters
934      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
935      TAF places a faulty re-call of initialise_varia
936      after cost_final call which should not be there!
937    checkpoint52j_pre
938    
939    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
940      error messages
941    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
942    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
943      debug output
944    o modfied mdsio_writefield.F to handle non-global files under exch2
945    o update AIM Cubed-Sphere exp (aim.5l_cs):
946      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
947    o update AIM Equatorial Channel exp:
948      use standard aim_v23 pkg and change the SST fields to be more realistic.
949    o globalFile now works with exch2
950    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
951      mon_vort3.F to make exch2 friendly with >1 tile per cube face
952    o limit timeave output for hi-res integrations
953    
954    checkpoint52i_post
955    o removed CPP_EEOPTIONS.h from verification/*/code
956    o updated the tiling for global_ocean_pressure
957    checkpoint52i_pre
958    
959    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
960      the old pkg/aim).
961    
962    checkpoint52h_pre
963    o shortened offending lines in exch2_send_rx?.template
964    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
965    o genmake2: add build & execute test for NetCDF code
966    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
967      old grid files, moved CPP_EEMACROS.h to pkg/exch2
968    o added useSingleCPUIO flag to monitor.F and mon_out.F
969    o added temporary hack for sea-ice dynamics on the cube:
970      metric terms are ignored and it is assumed that
971      there is no sea-ice on cube faces 1, 2, 4, and 5.
972    
973    checkpoint52f_post
974    o added exch2 cube routines to pkg/exch2
975    o modified hs94.cs-32x32x5 to use it
976    o added new grid files to hs94.cs-32x32x5
977    checkpoint52f_pre
978    
979    checkpoint52e_post
980    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
981      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
982    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
983      to work with implicit vertical advection and AB ;
984    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
985    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
986     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
987    checkpoint52e_pre
988    
989    o fix bug in impldiff when Nr=1 or Nr=2.
990  o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt  o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
