7    checkpoint57t_post
8    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
9    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
10      same truncation, independent of the face number: affects affects several
11      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
12    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
13      note that biharmonic viscosity + no-slip was not tested in any experiment.
14    o fix bug in non-linear free-surf side-drag ; generate new output for
15      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
16    o make mnc honor the writeBinaryPrec flag for most kinds of output
17    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
18    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
19      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
20    o add brackets in multi-terms sum to get same truncation, independent of
21      the face number (manage to get exactly same value of gU,gV at the cs-edge)
22      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
23    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
24      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
25      a maximum grid-scale Reynolds number.  Also, changes all length calculations
26      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
27      Suggested values of viscosity parameters found in mom_calc_visc.
28      Many new viscosity diagnostics available.
29    
30    checkpoint57s_post
31    o Add clearing-house for viscosity calculations, mom_calc_visc and
32      correct numerous bugs in LeithD and Smagorinsky discretizations.  
33      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
34      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
35      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
36      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
37      The Strain-Tension form is now called with useStrainTensonVisc=.true.
38      ViscAhStrain and viscAhTension are now retired.
39    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
40    o In response to JMC's bug report, genmake2 now ignores any soft-links
41      that it finds in the *current* directory when searching for files.
42      Soft-links found in any other source directories will still work as
43      they did before.
44    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
45      a C routine to unlimit the stack size
46    o mnc-ify pkg/aim snapshot vars
47    o mnc-ify pkg/land as requested by Daniel
48    o various changes to mnc including:
49      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
50      - output can now be grouped so that all files within a group
51          change the ITER portion of their names in lock-step together
52      - can now read ("global") PER-FACE (in addition to PER-TILE) files
53          and works with both EXCH1 and EXCH2 (but needs more testing)
54      - writing works for all verification test cases w/ g77 on Linux
55    
56    checkpoint57r_post
57    o make MNC variable initialization happen earlier
58    o add diagnostics for (almost) each term of the momentum Eq.
59    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
60    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
61    o remove MINIMAL_TAVE_OUTPUT option ;
62      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
63    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
64      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
65    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
66    o add time-dependent SST, SSS control
67    o cost terms in ecco/ modularized (new cost_generic.F)
68    o cost_averages routines are modularized (new cost_averagesgeneric.F)
69    o new infrastructure for seaice model vs. obs misfits in seaice/
70      * driver from the_main_loop.F is seaice_cost_driver.F
71      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
72      * gradient check in Exp. 6a of natl_box_adjoint/
73    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
74      (see README file)
75    
76    checkpoint57q_post
77    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
78    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
79      - bug was reported by Jean-Michel and Ian Fenty
80    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
81      update exp. cpl_aim+ocn output.
82    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
83      Needed for high-res. runs with large global files
84      to be able to limit tapelev size
85    o Changed some tests for adjoint:
86      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
87      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
88      * global_ocean.90x40x15/ back to default 3-level checkpointing
89    o Modifications to enable scripted COMMON to MODULE conversion
90      * verification/OpenAD/code/ has necessary scripts and description;
91      * converts, compiles and runs successfully;
92    
93    checkpoint57p_post
94    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
95    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
96      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
97    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
98    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
99      (was already the case for dissipation with mom_vecinv,
100       and also the case for grad.PhiHyd when staggered-timeStep)
101      This will allow to put dissipation out-off the AB time-stepping.
102     Unfortunately, affects truncation error. Update output of exp. that "fails"
103      (cg2d matching number) and leave the others for later: front_relax(10),
104      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
105      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
106    
107    checkpoint57o_post
108    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
109      (2) its ready to be documented during the 20050801 DocFest
110    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
111      for ideal_2D_oce and lab_sea on linux_ia32_g77
112    o set to #undef CTRL_SET_OLD_MAXCVARS_30
113      in global1x1_tot/code_seaice_adj to access indices 32, 33
114      (worth another tag)
115    
116    checkpoint57n_post
117    o adding precip control xx_precip 32
118    o adding swflux control xx_swflux 33
119    o Replacing 10 forcing penalty cost routines by 1 generic.
120    o Implementing partitioning in time-mean and variable adjustment
121      for atmos. state.
122    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
123    o in natl_box_adjoint:
124      * updated exp 1 to 10
125        (but does not have time-mean vs. variable split results yet)
126    o updated global1x1/*_seaice_adj/
127      to incorporate latest changes
128    o enable useSingleCpuIO for mdsio vector routines
129      (applies in particular to tapelev I/O)
130    o removed inefficient K-loop in all active_file*control*.F
131    
132    checkpoint57m_post
133    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
134      and advect_cs (use EXCH-2 and standard cs-32 grid files).
135    o pkg/exch2: filling of face-corner halo regions is optional
136      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
137    
138    checkpoint57l_post
139     tag before updating tutorials (pre-release-2)
140    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
141       for output and interpolation of input fields onto model grid)
142    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
143       Affects results of exp. rotating_tank ; update output.txt.
144    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
145          and taking the square quantity and/or using a fraction-weight field.
146    o fix aim_diagnostics_init.F mate numbers.
147    o add mnc output capability to diagnostics/diagstat and update
148      our cvsignore files for the ACSII output generated
149    
150    checkpoint57k_post
151    o lab_sea now uses diagnostics package and provides a suite of
152      new EXF diagnostics output.
153    
154    checkpoint57j_post
155    o exf
156      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
157        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
158        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
159      * extended diagnostics output
160        - now includes all EXF variables
161        - hs, hl moved to common block
162        - separate S/R for diagnostics, called after ctrl vector is added
163        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
164        - EXFqnet contains true Qnet (i.e. includes qsw)
165      * updated verif. lab_sea, global_with_exf
166      * Rearranging hflux (exf_mapfields -> exf_getforcing)
167        to ensure that diagnostics sees a true EXFqnet
168    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
169    o diagnostics pkg: change pointers so that 1 diagnostic can be used
170      several times with different frequencies.
171    o mnc-ify the thsice package as requested by Daniel Enderton
172      - the monitor--MNC output needs work
173      - many attributes need to be added (most are currently blank)
174    o mnc-ify theaim_v23 package as requested by Daniel Enderton
175      - many attributes need to be added (most are currently blank)
176    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
177    o add Sadourny like discretization to the 4th.O vorticity advection scheme
178    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
179      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
180         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
181    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
182     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
183    
184    checkpoint57i_post
185    o Diagnostics package was changed: diagnostic allocation is now deactivated
186      by setting an empty file name in the namelist (used to be by setting 0 frequency)
187    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
188      add 1rst Order upwind vertical Shear.
189    o add a quick fix for A/B checkpointing in OFFLINE mode
190    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
191      end-run around the C/Fortran linking horror in eesup/src/timers.F
192    o added pkg/runclock: allows user to terminate run based on wall clock
193    o added non-hydrostatic scaling parameter: nh_am2
194    o pkg/my82: futile attempt to make results compiler-independent by adding
195      some "_d 0", etc. no effect.
196    o for mnc output, fill the 'T' coordinate var with myTime and create a
197      separate 'iter' variable for iteration count
198    o pkg/diagnostics:
199      add new capability: output of Global/Regional & per-level statistics ;
200      tested against monitor output (including land & thSIce) on various exp.
201    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
202    
203    checkpoint57h_done
204      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
205      data.diagnostics, data.gchem, data.ptracers) is done.
206    
207    o pkg/diagnostics: prepare for Global/Regional statistics.
208      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
209    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
210      and rename it: DIFFERENT_MULTIPLE
211    
212    checkpoint57h_post
213    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
214    o pkg/diagnostics: change output frequency, now in seconds (instead
215      of Nb of iterations). This requires to change data.diagnostics.
216    checkpoint57h_pre
217    
218    o in mnc, let the user create the output dir if both mnc_outdir_date
219      and mnc_outdir_num are false
220    o add fflags() to pkg/diagnostics which allows one to specify, on a
221      per-file basis, the file precision [default behavior is unchanged]
222    o added diagnostics to pkg/kpp, including computation of mixed layer
223      depth based on a temperature/density criterion
224    o updated verification/natl_box to test the new pkg/kpp diagnostics
225    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
226    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
227    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
228      not mnc -- this mistake was found by JMC and is now corrected
229    
230    checkpoint57g_post
231    o add Adams-Bashforth 3rd Order time stepping:
232      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
233      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
234    checkpoint57g_pre
235    
236    o make lambda[Theta,Salt]ClimRelax spatially varying
237      (default remains spatially uniform constant based on tau)
238    o added new control variables
239      * init. uVel, vVel, etanN
240      * lambda[Theta,Salt]ClimRelax
241    o separate masks used for ctrl_pack/unpack 'from write_grid' output
242      (suggested by G. Forget)
243    
244    checkpoint57f_post
245    o add parameter "baseTime" = model base time = time at iteration zero
246      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
247      account for baseTime shift
248    o move Coriolis arrays from PARAMS.h to GRID.h
249    checkpoint57f_pre
250    
251    o mnc-ifying the seaice package
252    o introduced an alternative length scale calculation for use in the limiting
253      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
254    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
255    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
256      as well as grad(vort3).  Made it compatible with both approximate form
257      for the cubed sphere and full form of these gradients.  Added flag
258      useFullLeith to select between approximate and full form.  
259    o add "d0" in getcon.F to reduce differences between compilers/platforms
260      update output.txt of exp. fizhi-gridalt-hs
261    o change port_rand funtion to allow to set the seed.
262    o fix obscure MNC bug involving conversion between reals and integers
263      - it caused no problems with certain (eg. gcc, ifc) compilers but the
264        new version is now more standards-compliant
265    o adjoint-related modifications
266      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
267      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
268      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
269    
270    checkpoint57e_post
271    o Adding eddy stress controls a la Ferreira et al.
272    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
273    
274    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
275      update output.txt of exp. fizhi-gridalt-hs
276    o add more "Z" dimensions and associated coordinate vars to MNC
277    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
278    o parameter calendarDumps: when set, approximate months (30-31 days) and years
279      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
280      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
281      months and years.  Requires pkg/cal.
282    o diagnostics: add pickup functionality
283      - off by default for backwards compatibility
284      - current version only uses MDSIO -- MNC will be added
285    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
286    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
287    
288    checkpoint57d_post
289    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
290    o modify verification/ideal_2D_oce so that it tests the creation of mnc
291      output from the diagnostics package
292    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
293    o make genmake2 more portable by using ".$FS" instead of ".f" for more
294      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
295    o add coordinate variables to the MNC output from the diagnostics package
296    o change MNC-flags default value: true when useMNC=TRUE
297    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
298      the ability (off by default) to read the grid information using MNC
299    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
300    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
301    o do snap-shot diagnostics at the middle of the time-interval (instead of
302      at the end).
303    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
304      new test for AIM with thSIce + slab-ocean
305    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
306    o move state variable diagnostics to the beginning of the time step ;
307      (note: still needs some work specially for snap-shot diagnostics)
308      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
309    
310    checkpoint57c_post
311    o Change testing option (-ieee) to get closer agreement between g77 & ifort
312    o generate new output.txt files on faulks with g77 & the new -ieee option
313    checkpoint57c_pre
314    
315    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
316      update output.txt of exp. global_ocean.90x40x15
317    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
318      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
319    o add saltFlux(+File) forcing capability with periodicExternalForcing
320    o allow to use pkg diagnostics for GM-Redi & ThSIce output
321    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
322    o improvements for the MNC output from DIAGNOSTICS:
323      - correct handling of the unlimitied dimension
324      - all dims now have associated coordinate variables
325      - variables located at U, V, and Corner ("Z") points are now written
326        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
327        *all* data points are output
328    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
329    o added pkg/seaice/seaice_monitor.F
330    o mdsio_readfield.F can now read files visible only to master MPI process.
331    o pkg/seaice: some test code for ice-modified ocean stress
332    o exf_getffields interpolation defaults to bilinear for all scalar forcing
333      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
334      spurious negative numbers for precipitation and humidity.  Will cause
335      some small numerical differences for integrations using pkg/exf/exf_interp.F.
336    o pkg/ctrl/
337      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
338        May be enabled via doPackDiag
339      *  introduce z-scaling of
340         + gradient (doZscalePack) and
341         + control (doZscaleUnpack)
342    o pkg/mdsio/
343      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
344      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
345    
346    checkpoint57b_post
347    o simplify options in diagnostics_fill arguments (remove weird combinations)
348    o fix MNC coordinate variables so that they now contain per-face index
349      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
350      general, EXCH2 grids are only aligned to a "local" coordinate system
351    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
352    o Implement instantaneous output within pkg diagnostics:
353      setting a negative frequency in data.diagnostics produces
354     "snap-shot" output (as opposed to time-average if freq > 0)
355    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
356      NOTE: change ptracer diagnostics name: use 2 characters to work with
357            more than 9 tracers. Add also diagnostics of advect & diffus flux.
358    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
359      becomes the coordinate variable for the 'T' dimension
360    o add CF-style coordinate variables to MNC
361      - just a first cut:  numbers are meaningless on the cubesphere and
362        missing along the T axis but otherwise it works!
363    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
364    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
365    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
366      this is based directly on what the model compute, so that the content of
367      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
368    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
369    o clean up build options files for SunOS, in particular
370      - remove -traditional from xmakedepend
371      - change -xarch=v9 to -xarch=native for f77
372      - restore use of make (not gmake)
373      - add CC=gcc if using g77
374    o changes per discussion of AM, JMC, & EH3 today:
375      - move redundant "grid" variables out of "state" -- in preparation of
376        creating proper CF-style coordinate variables and in recognition
377        that any/all grid variables can be easily copied (eg. w/NCO) from
378        the grid files into any of the other NetCDF files
379      - *always* output grid variables with MDSIO (this will eventually be
380        changed)
381      - output MNC grid file if useMNC is true
382    o every instance of _END_MASTER() has been found and replaced with
383      _END_MASTER( myThid ) in order to satisfy certain picky Sun
384      preprocessors
385    o re-arrange diagnostics pkg initialisation:
386     - allow each package to extend the available diagnostics list
387     - add some checking and fix small problems (multi-threaded, ...)
388     - new S/R diagnostics_fill (replace fill_diagnostics):
389       look through the short list of active diag. (instead of the long list)
390       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
391    
392    checkpoint57a_post
393    o this set of changes restores TAMC compatibility
394      tested for global_ocean.90x40x15 adjoint on trough
395      (what a pain)
396    
397    checkpoint57a_pre
398    o some modifs in tools/build_options for sunos
399    o call ctrl_pack for ctrl at end for optimcycle=0
400    
401    checkpoint57
402    o add horizontal bi-harmonic viscosity for vertical velocity
403      - new parameter viscA4W (defaults to viscA4)
404      - affects only non-hydrostatic code
405      - to be done: no-slip lateral boundary conditions
406    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
407    o implement Implicit Vertical advection for pTracers
408    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
409      (implemented also for implicit vertical diffusion & advection)
410    o OBCS: extend application of tracer open boundary conditions
411      to a strip beyond the boundary of width Olx/Oly
412    o add call monitor to TAF set of required calls (flow directives)
413      and include in natl_box_adjoint
414    o untangle a few ifdefs related to cost, ctrl, autodiff
415      untangel a few ALLOW_ECCO_OPTIMIZATION
416    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
417      (theta2, salt2 in ecco_cost_weights)
418    
419    checkpoint56c_post
420    o OBCS as control variables
421      - update ctrl_ad_diff.list, obcs_ad_diff.list
422      - remove balance of obcs controls from default
423      - fix index bug nobcs in ctrl_init
424      - fix dummy fields filen in ctrl_pack
425      - add dummy weights for obcs
426    o lsopt: comment out fort.94 output
427    o optim:
428      - remove unnecessary header files
429      - adjusted namelists
430      - add xerbla.F to Makefile
431    o exf:
432      - multiple modifications of exf_check_range
433      - unit change in exf_init_runoff from [m/year] to [m/s]
434    o mdsio:
435      - i/o-vector change debugLevel from debLevA to debLevB
436    
437    checkpoint56b_post
438    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
439      is called from DO_THE_MODEL_IO
440      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
441      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
442      - clean up PTRACERS_WRITE_TIMEAVE a little
443    o add another verification experiment that tests both the cfc-pkg and
444      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
445      reactive tendencies treated inline with regular timestepping
446    o testreport previously did a lousy job of comparing small numbers, so
447      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
448      implemented in the little c-progam tmp_cmpnum.c which is embedded in
449      testreport.
450    o ptracers_monitor: bug fix for MPI
451    
452    checkpoint56a_post
453    o GCHEM: finish reorganizating the package
454      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
455        (introduces another 3D-array for each passive tracer, but only if
456        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
457        gchemTendency is not needed because the timestep is done separately)
458      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
459      - GCHEM is now---more or less cleanly---separate from PTRACERS
460      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
461        so clear to me how that should be done in a general way.
462    o CFC: improve formatting of output in CFC_ATMOS
463    o PTRACERS:
464      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
465        that ALL experiments with ptracers enable can be checked. This makes
466        GCHEM_MONITOR obsolete.
467      - include a runtime parameter PTRACERS_monitorFreq that defaults to
468        monitorFreq
469      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
470    o add PTRACERS (PTR0[1-5]) to testreport output
471    o exf_check_range:
472      * default changed to .TRUE.
473      * will check values for niter0 if debLevA, every timestep if debLevB
474      * STOP in exf_check_range if 'out of range'
475      * range chosen generous to allow for potential extema
476      TBD: a version with stricter range
477           permitted range would be runtime parameters
478    o GMredi:
479      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
480      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
481      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
482    o GCHEM:
483      - move call to GCHEM_FORCING_SEP, so that it is now called before
484        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
485      - introduced a useGCHEM runtime flag and applied it everywhere.
486      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
487        this flag is now only visible within GCHEM-pkg routines.
488      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
489        be replaced by a 3D array that is computed before thermodynamics; for
490        this, the tracer ID iTracer had to be included into the parameter list
491        of ptracers_forcing
492      - set up forward_step to call gchem_forcing, that will replace
493        gchem_forcing_int in ptracers_forcing
494      - cleaning up
495    o small cleaning of exch2: remove files that are also in eesupp/src
496    
497    checkpoint56
498    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
499    o mnc: cleanup "full" files--fixes out-of-memory problem
500    o ECCO-GODAE
501      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
502      * fully merged and updated from SIO code
503        windstress sign change affects
504        - exf_inscal_[u/v]stress
505        - sign of xx_tau[u/v] adjustments
506        - signs in cost_scat
507      * ctrl_get_gen: avoid update of tau[u/v] for first few days
508      * natl_box_adjoint updated and compressed
509      * 2-level checkpoint switch added
510        (tested in EXP. 1 of natl_box_adjoint)
511      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
512    o SVD
513      * first complete, non-hacked version for SVD calculations
514      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
515        performed via direct access files admtlm_vector.it????
516        (via ctrl_[un]pack)
517      * optimcycle is used for ARPACK iteration counter
518        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
519      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
520        and add linear transforms where necessary
521      * controls are initial/final SST, SSS (can be extended; need to check
522        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
523    o mdsio: filename info to both stderr, stdout
524    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
525      from sign change
526    
527    checkpoint55j_post
528    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
529      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
530    o add consistent build directories and .cvsignore files to verification
531    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
532    o make all subroutines 30 or less characters in length for certain older
533      compilers to work (a thorough search only turns up two routines in
534      pkg/ptracers)
535    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
536      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
537    
538    checkpoint55i_post
539    o change arrays for total vertical diffusivity (2.D if explicit,
540      3.D if implicit) ; each ptracer uses its own background value.
541    o added mnc/NetCDF output capability to ocn_compon_interf
542      - added bits to verification/cpl_aim+ocn so that it can run on
543        ITRDA and other clusters without the mpirun "-wd" option
544    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
545      configuration
546    o give MNC the ability to create additional files rather than
547      exceeding a specified file size limit "MNC_MAX_FILESIZE"
548      - the default is just less than 2GB which is a practical limit
549        on many systems
550    o Compute the non-local term using either KPP vertical diffusivity (=default)
551       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
552    
553    checkpoint55h_post
554    o add verification test "vermix"
555    o remove all the *_ioinc flags and replace with the single global
556      outputTypesInclusive flag
557    o allow to set a vertical profile of vertical diffusivity for T & S
558    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
559    o useMNC moved from data.mnc to data.pkg
560    
561    checkpoint55g_post
562    o Renaming carbon AD experiments to comply with testreport conventions
563    o Updating adjoint of Held-Suarez hs94.1x64x5
564    o Fixing directives for non-ECCO forward_step, after ECCO directives
565      have been fixed to avoid recomp. of do_oceanic_phys
566      Works well for global_ocean.90x40x15,
567      but recomp. issue remains for carbon
568    o Updating adjoint output for natl_box_adjoint after
569      pkg/ecco has been modified (see taga c55d_post)
570    
571    checkpoint55f_post
572    o rename to timeave_init_fixed
573    
574    checkpoint55e_post
575    o some delicate re-shuffle of store directives to avoid one
576      extra call of do_oceanic_physics
577      affects ecco_the_main_loop.F, do_oceanic_physics.F
578      checkpoint_lev1_directives.h
579    o NB: this may break global_ocean adjoint temporarily,
580      but it is clear how to fix it. Will do later, need this now.
581    
582    checkpoint55d_post
583    o ECCO specific cost function terms (up-to-date with 1x1 runs)
584    o ecco_cost_weights is modified to 1x1 runs
585    o modifs to allow observations to be read in as
586      single file or yearly files
587    o enable to read exf forcing fields as either
588      single file or yearly files (flag useExfYearlyFields)
589    checkpoint55d_pre
590    
591    o switch between 2-level and 3-level checkpointing
592    o add ability of MNC to write local and "partial" (eg. 2D slices where
593      the full 3D field is never actually stored) arrays to NetCDF files
594      with the correct (that is, the complete multi-dimensional) set of
595      array indicies
596      - used in mom_vecinv() to write the diagFreq output
597      - tested (demonstrated) in verification/aim.5l_cs
598    o further mnc-ification
599      - add verification/lab_sea to the list with mnc setups
600      - fix undefined mnc v-names in cd_code
601      - add kpp to mnc output (both snapshot and timeave)
602    o non-hydrostatic code
603      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
604        in calc_gw.F
605      - defaults to viscAh
606      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
607        friction or Leith) in non-hydrostatic mode, as long as there is
608        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
609    o pkg/cost
610      extend simple cost functions to treat time mean quantities
611      (T,U,V) via cost_accumulate_state from cost_tile
612    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
613        be 2 times larger than the minimum size the advection scheme requires.
614        now get a perfect conservation of salt in advect_cs test-exp (updated)
615    o GGL90 (Gaspar's TKE mixed layer)
616      - add horizontal diffusion of TKE, requires exchanges in
617        do_fields_blocking_exchanges, horizontal diffusivity is zero by
618        default. In OPA there is no horizontal diffusion of TKE but the
619        mixing coefficients are computed from a horizontal average of TKE of
620        6 points or so. I think that diffusion has a little more physical
621        justification.
622      - clean up ggl90_calc in the hope of reducing memory usage (this hope
623        was in vain)
624      - mask tke-variable in ggl90_init
625    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
626    o fix biharmonic diffusion on CS-grid.
627    o more obcs stuff
628      - added obcs_external_fields_load as an alternative to the EXF-pkg option
629        for reading boundary values. This routine is called from
630        obcs_prescribe_read
631      - updated obcs_check
632      - changed sponge layer relaxation parameter units for days to seconds
633      - turned off sponge layer by default
634      - changed argument list of OBCS_CALC to myTime+deltaTclock
635      - fixed about 35 bugs in obcs_external_fields_load
636    
637    checkpoint55c_post
638    o obcs stuff
639      - new runtime flags useOBCSprescribe, useOBCSbalance
640      - re-arranged obcs_calc
641      - moved exf_getobcs to obcs_prescibe_read
642        obcs_prescibe_read is called after ORLANSKI stuff
643        and independent of it (executable can contain all).
644      - updated obcs_check
645      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
646        These may be necessary only if tangential velocities are
647        prescribed at OB, not sure, needs testing.
648    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
649      which simplifies the calls and passes the ifc check-bounds test
650    
651    checkpoint55b_post
652    o add a 2D scalar, Z location, exchange_2 routine.
653    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
654      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
655      affects advect_cs results (for the wrong reason): update output.txt
656    o use a more standard discretization for biharmonic viscosity ;
657     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
658      affects results of dome set-up: update output.txt
659    o fix gad_advection.F (CubedSphere part), back to version 1.23
660    o fix bug in mom_vi_del2uv.F (CubedSphere part).
661    
662    checkpoint55a_post
663    o merged code to
664      * prescribe/read time-dependent open boundaries
665        (works in conjunction with exf, cal)
666      * sponge layer code for open boundaries
667      * each boundary N/S/E/W now has its own CPP option
668        (healthy for the adjoint)
669    
670    checkpoint55
671    o up-to-date adjoint of previous breaks
672      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
673      - global_ocean_ebm: adjoint still needs fix (TLM ok)
674      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
675      - carbon: * remove tr1-related adjoint verification
676                * add ptracer as control variable
677    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
678      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
679    
680    checkpoint54f_post
681    o in verification/carbin/ remove experiment related to
682      ALLOW_PASSIVE_TRACER (array tr1 etc)
683      code_ad/ input_ad/ results_ad
684    
685    o add two new packages
686      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
687        + subject to optimization (memory)
688      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
689        + subject to reordering (many GOTOs in the original code)
690        + so far opps is called for every (i,j) point, and then operates in
691          the vertical; one may want to reorder the scheme in order operate in
692          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
693          fields)
694    o overhaul of IO so that we now have flags for MDSIO and/or MNC
695      - all verification tests compile and run with linux_ia32_g77
696      - defaults are compatible with current input files--nothing
697        should change if you were not previously using MNC
698      - MNC output has been added in numerous places (eg. timeave)
699        but there are still a few writes not yet do-able with MNC
700        (this is in progress)
701      - flags now allow for either/or/both use of MDSIO and MNC and
702        documentation will soon follow
703      - numerous small formatting cleanups for ProTeX
704    o add version info (via BUILD_INFO.h) to MNC and stdout
705    
706    checkpoint54e_post
707    o add two new packages
708      - pp81 (Packanowski and Philander, 1981), Richardson number and
709        stratification dependent mixing
710      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
711      - these scheme operate in a similar manner as KPP (without ghat, of
712        course), however there is only one diffusivity that is used for both
713        temperature and salinity (and passive tracers)ç
714    o add offline package
715    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
716      provided by Stephanie Dutkiewicz
717    o genmake2: add ability to search for C compilers and cleanup test output
718      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
719    
720    checkpoint54d_post
721    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
722    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
723      leading to additional shift by 5 days each year of integration
724       (i.e. leading to considerable offset over the years)
725    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
726    o start with no AB and no initial filtering (staggerTimeStep):
727      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
728    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
729      (external loading & cpl import/export stay in forward_step.F)
730    o update coupling interface to work with new staggerTimeStep
731    o change MDSIO ptracers_pickup.
732    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
733    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
734    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
735    
736    checkpoint54c_post
737    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
738      this affects (truncation error) output.txt of test-exp:
739       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
740    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
741    o change Qnet to always be the net heat flux, (+upward).
742      affects (truncation error) output of natl_box exp.: updated
743    o define the max number of passive tracers in PTRACERS_SIZE.h
744    o start to test mnc routinely in exp0
745    o add sea-ice loading (sIceLoad) as a new forcing field.
746    
747    checkpoint54b_post
748    o add testreport "-j JOBS" option for parallel builds (tested and pretty
749       impressive on Altix and Opteron systems)
750    o diagnostics can now write NetCDF files through the mnc package
751    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
752    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
753    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
754      affects (truncation error) output of lab_sea & natl_box exp.: updated
755    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
756    
757    checkpoint54a_post
758    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
759    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
760    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
761    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
762      + internal_wave (shift in writing cg2d_ini_res)
763    checkpoint54a_pre
764    
765    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
766      - modified verification/lab_sea and natl_box_adjoint accordingly
767    
768    checkpoint54
769    checkpoint53g_post
770    o prepare splitting of thermodynamics: store convect.counter in common block
771    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
772      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
773    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
774    o new parameter "nShapS": allow to treat differently S from T (nShapT)
775    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
776    o restore adjointability
777    
778    checkpoint53f_post
779    o modifications that affect AIM experiment results (update output.txt):
780      - no advection of S at top interface Nr (pkg/generic_advdiff)
781      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
782    o AIM pkg:
783      - include stability function into surf.Flux derivative relative to Tsurf
784      - calculate clear-sky radiation & surface temp. change (for diagnostics)
785    
786    checkpoint53e_post
787    o merged cylindrical coord configuration
788    o added rotating_tank experiment
789    checkpoint53e_pre
790    
791    checkpoint53d_post
792    o faulks upgraded: re-generate output.txt that have changed:
793       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
794    o Added Bryan and Lewis, 1979, vertical diffusivity profile
795    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
796    o added Sadourny discretization of Coriolis
797      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
798      - re-enabled use of omega3 (useAbsVorticity)
799    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
800      vector-invariant equations
801      - note: does *NOT* yet use same variable visc. for no-slip BC's.
802    o recoded the lateral boundary conditions for non-hydrostatic w, this time
803      hopefully without new bugs
804      - still to do: biharmonic friction for non-hydrostatic w
805    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
806    o regenerated output for global_ocean_ebm (using -ieee)
807    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
808      of mom_common/
809      - simple re-arrangement of instructions within computing loop
810    checkpoint53d_pre
811    
812    checkpoint53c_post
813    o new version of coupler for AIM+thSIce and Ocean models
814     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
815     - land: change Evaporation of snow
816     - aim with thSIce: fix bug in snow-precip.
817    o changes to calc_gw.F
818     - bug fix for w^2 term near the bottom boundary
819     - (hopefully) improve the lateral slip boundary condtions for use with
820        partial/looped cells
821      - because the bug fix changes two verification experiments anyway (exp5
822        and plume on slope), change the lateral boundary condition from half slip
823        to the value of no_slip_sides
824    o ebm package wasnt quite up to the parallel task. Fixed that.
825    o Adjoint of EBM package + verification
826      * TLM OK
827      * ADM not sufficient accuracy yet (needs further testing)
828    
829    checkpoint53b_post
830    o Commiting new energy balance model to repository
831      * package is pkg/ebm
832      * verif. is verification/global_ocean_ebm
833      * references are in ebm_driver.F
834    C      * X. Wang, P. Stone and J. Marotzke, 1999:
835    C        Global thermohaline circulation. Part I:
836    C        Sensitivity to atmospheric moisture transport.

838    C      * X. Wang, P. Stone and J. Marotzke, 1999:
839    C        Global thermohaline circulation. Part II:

842    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
843    C        Destabilization of the thermohaline circulation
844    C        by atmospheric eddy transports.
845    C        J. Climate 7(12), 1870-1882
846    o Will need long integration testing.
847    checkpoint53b_pre
848    
849    o created pkg/mom_common in preparation for variable viscosity code
850    o renamed and split ini_mnc_io
851    o pkg/land: only liquid water can diffuse or run-off
852    o AIM using land: soil wetness availability account for snow
853    o added printMapIncludesZeros to EEPARMS namelist
854    
855    checkpoint53a_post
856    o restore TAMC compatiility for exf_constants.h
857      (no usage of _d in .h)
858    o Additional storing in KPP in an attempt to fix
859      TAMC problem with adjoint of KPP code.
860      (no success...)
861      Identical code works fine with TAF.
862    o Fixed verification/natl_box_adjoint experiments.
863      Initial conditions for Experiments 4 and 5 are now
864      set to "SEAICE_initialHEFF=0", which is more reasonable,
865      and hence gives results closer to that of Experiment 2.
866      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
867    
868    checkpoint53
869    o stable checkpoint with up to date adjoint
870      TLM tests only run for 1st grdchk at the moment. Its unclear if
871      this is a code problem or a problem with resetting code for g_
872      variables that is being autogenerated wrong.
873      Otherwise:
874       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
875       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
876         are both still in chaos following their security messes.
877    
878    checkpoint52n_post
879    o various build (mostly genmake2) changes including:
880      - ability to build/run more easily within Cygwin and MacOS X
881      - more complicated Makefiles with a stronger dependence on Gnu Make
882    o pkg/seaice modifications
883      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
884        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
885        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
886      - changed proxy for geostrophic velocity and updated
887        verification/lab_sea/results/* accordingly
888      - removed ADI dynamic solver from pkg/seaice
889      - replaced all occurrences of 1/CSTICE or 1/CSUICE
890        they caused a segmentation fault under certain circumstances
891      - removed unused field WATR
892    o bug fix in exf-package:
893      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
894         now reflect that.
895    o small fixes in the cal-package:
896      - set reference date to first of January for the 'model'-calendar
897      - failing of cal_CheckDate in cal_FullDate now actually results in a
898        warning
899    o small modifications in exf-package to increase flexibility:
900      - change climtempfreeze from a constant to a runtime parameter that
901        is specified in data.exf_clim (default = -1.9)
902      - introduce runtime parameter windstressmax (default = 2.0) that is
903        specified in data.exf
904    o fix in pkg/thsice:
905      - update Evap (Tsf changes) to be consistent with Latent heat flux
906      - maintain snow precipitation unchanged (even if Tsf >=0).
907     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
908    
909    checkpoint52m_post
910    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
911      this does not change any of the results, because myIter=0 in swfrac always
912      lead to jwtype=2 (the default anyway), but the call makes little sense
913      as a default
914    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
915    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
916      atmospheric model (AIM) to use it ; add a "slab ocean" component.
917    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
918    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
919    o extending useSingleCpuIO option to work with new exch2 I/O format
920      - old-style, missing-tile I/O is still accessible by defining CPP
921        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
922    o monitor package can write to NetCDF files and/or STDOUT
923    o fix re-definition bug in MNC_GRID_INIT_ALL()
924    o doc/api_reference added
925      - a framework for building an API Reference Manual using all
926        the "protex" comments embedded in the code
927      - see pkg/generic_advdiff, pkg/mnc for examples
928    o MNC:
929      - make myThid the last argument for all subroutines
930      - new default for the grid files: NO halos
931      - add useMNC and other run-time flags
932      - separate per-file-group handling of the unlimited dimension
933      - early initialization of MNC w/ flags read at the eeboot stage
934        and lookup tables set in initialize_fixed
935      - write all MNC output to a freshly-created directory
936    o thermodynamics sea-ice (thsice) is now tested with testreport.
937    o test exp. advect_cs: use the standard cs32 grid ; update output.
938    o Added functionality to grdchk:
939      pick global i,j,k position (or nearest wet) where to perform check.
940    
941    checkpoint52l_post
942    o new land formulation:
943      a) use ground enthalpy as prognostic variable to ensure exact
944         energy conservation.
945      b) account for water temperature and for latent heat of freezing
946         in all processes (rain, run-off, ground storage)
947      c) compute surface and ground temperature implicitly.
948    o aim_v23 modification for new land model:
949      a) Treat separately land / ocean / sea-ice surface fluxes
950         to allow implicit computation of land & sea-ice surface temp.
951      b) add snow precipitation.
952    checkpoint52l_pre
953    
954    o fix problem (when 1 tile is empty) in min/max monitor.
955    o fix bug in timeAve (u,vZetatave in common block)
956    o no restoring terms under ice for pkg/seaice
957    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
958    o bug fix for pkg/seaice pickups
959    o change MNC call locations and add coordinate attributes
960    o mask vorticity at the corner ; affects global_ocean.cs output
961    o fix ini_curvilinear_grid ; test CS experiments with mpi
962    o aim.5l_cs: modify sea-ice fraction input file ; update output
963    o exf: Adding simple range check routine for exf fields after read
964    
965    checkpoint52k_post
966    o removed top-level directory "diags"
967      - we migrated these functions to pkg/timeave a long time ago
968    o fixed bug introduced in pkg/monitor
969    o accuracy ctrlprec = 32 insuffient for gradient checks using
970      averaged fields (I/O via cost_averages)
971      -> use ctrl.h in active_file*.F to control I/O precision.
972    o paramter list of CALL ADTHE_MAIN_LOOP
973    o added initial do_the_model_io to ecco
974    o set all ...Freq to zero after cost_final
975      taveFreq, dumpFreq, pChkptFreq
976    o MAIN and ECCO differentiability restored
977    
978    checkpoint52j_post
979    o fix nchklev in tamc.h for global_ocean...
980    o Bringing flow and store directives up-to-date
981    o Really weird thing!
982      call do_the_model_io from the_main_loop with parameters
983      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
984      TAF places a faulty re-call of initialise_varia
985      after cost_final call which should not be there!
986    checkpoint52j_pre
987    
988    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
989      error messages
990    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
991    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
992      debug output
993    o modfied mdsio_writefield.F to handle non-global files under exch2
994    o update AIM Cubed-Sphere exp (aim.5l_cs):
995      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
996    o update AIM Equatorial Channel exp:
997      use standard aim_v23 pkg and change the SST fields to be more realistic.
998    o globalFile now works with exch2
999    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1000      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1001    o limit timeave output for hi-res integrations
1002    
1003    checkpoint52i_post
1004    o removed CPP_EEOPTIONS.h from verification/*/code
1005    o updated the tiling for global_ocean_pressure
1006    checkpoint52i_pre
1007    
1008    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1009      the old pkg/aim).
1010    
1011    checkpoint52h_pre
1012    o shortened offending lines in exch2_send_rx?.template
1013    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1014    o genmake2: add build & execute test for NetCDF code
1015    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1016      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1017    o added useSingleCPUIO flag to monitor.F and mon_out.F
1018    o added temporary hack for sea-ice dynamics on the cube:
1019      metric terms are ignored and it is assumed that
1020      there is no sea-ice on cube faces 1, 2, 4, and 5.
1021    
1022    checkpoint52f_post
1023    o added exch2 cube routines to pkg/exch2
1024    o modified hs94.cs-32x32x5 to use it
1025    o added new grid files to hs94.cs-32x32x5
1026    checkpoint52f_pre
1027    
1028    checkpoint52e_post
1029    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1030      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1031    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1032      to work with implicit vertical advection and AB ;
1033    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1034    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1035     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1036    checkpoint52e_pre
1037    
1038    o fix bug in impldiff when Nr=1 or Nr=2.
1039    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1040    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1041    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1042      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1043    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1044    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1045    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1046    
1047    checkpoint52d_post
1048    o re-tiled many expts to allow comparison in multi-processor mode
1049      - updated output accordingly
1050      - changed hs94.128x64x5 to use intial T from file rather than use the
1051        random number generator
1052    o add infrastructure in model routines for fizhi and gridalt packages
1053  o change global_ocean.cs32x15 because of Pb with GM on CS-grid.  o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
