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

794    o Will need long integration testing.
795    checkpoint53b_pre
796    
797    o created pkg/mom_common in preparation for variable viscosity code
798    o renamed and split ini_mnc_io
799    o pkg/land: only liquid water can diffuse or run-off
800    o AIM using land: soil wetness availability account for snow
801    o added printMapIncludesZeros to EEPARMS namelist
802    
803    checkpoint53a_post
804    o restore TAMC compatiility for exf_constants.h
805      (no usage of _d in .h)
806    o Additional storing in KPP in an attempt to fix
807      TAMC problem with adjoint of KPP code.
808      (no success...)
809      Identical code works fine with TAF.
810    o Fixed verification/natl_box_adjoint experiments.
811      Initial conditions for Experiments 4 and 5 are now
812      set to "SEAICE_initialHEFF=0", which is more reasonable,
813      and hence gives results closer to that of Experiment 2.
814      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
815    
816    checkpoint53
817    o stable checkpoint with up to date adjoint
818      TLM tests only run for 1st grdchk at the moment. Its unclear if
819      this is a code problem or a problem with resetting code for g_
820      variables that is being autogenerated wrong.
821      Otherwise:
822       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
823       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
824         are both still in chaos following their security messes.
825    
826    checkpoint52n_post
827    o various build (mostly genmake2) changes including:
828      - ability to build/run more easily within Cygwin and MacOS X
829      - more complicated Makefiles with a stronger dependence on Gnu Make
830    o pkg/seaice modifications
831      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
832        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
833        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
834      - changed proxy for geostrophic velocity and updated
835        verification/lab_sea/results/* accordingly
836      - removed ADI dynamic solver from pkg/seaice
837      - replaced all occurrences of 1/CSTICE or 1/CSUICE
838        they caused a segmentation fault under certain circumstances
839      - removed unused field WATR
840    o bug fix in exf-package:
841      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
842         now reflect that.
843    o small fixes in the cal-package:
844      - set reference date to first of January for the 'model'-calendar
845      - failing of cal_CheckDate in cal_FullDate now actually results in a
846        warning
847    o small modifications in exf-package to increase flexibility:
848      - change climtempfreeze from a constant to a runtime parameter that
849        is specified in data.exf_clim (default = -1.9)
850      - introduce runtime parameter windstressmax (default = 2.0) that is
851        specified in data.exf
852    o fix in pkg/thsice:
853      - update Evap (Tsf changes) to be consistent with Latent heat flux
854      - maintain snow precipitation unchanged (even if Tsf >=0).
855     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
856    
857    checkpoint52m_post
858    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
859      this does not change any of the results, because myIter=0 in swfrac always
860      lead to jwtype=2 (the default anyway), but the call makes little sense
861      as a default
862    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
863    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
864      atmospheric model (AIM) to use it ; add a "slab ocean" component.
865    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
866    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
867    o extending useSingleCpuIO option to work with new exch2 I/O format
868      - old-style, missing-tile I/O is still accessible by defining CPP
869        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
870    o monitor package can write to NetCDF files and/or STDOUT
871    o fix re-definition bug in MNC_GRID_INIT_ALL()
872    o doc/api_reference added
873      - a framework for building an API Reference Manual using all
874        the "protex" comments embedded in the code
875      - see pkg/generic_advdiff, pkg/mnc for examples
876    o MNC:
877      - make myThid the last argument for all subroutines
878      - new default for the grid files: NO halos
879      - add useMNC and other run-time flags
880      - separate per-file-group handling of the unlimited dimension
881      - early initialization of MNC w/ flags read at the eeboot stage
882        and lookup tables set in initialize_fixed
883      - write all MNC output to a freshly-created directory
884    o thermodynamics sea-ice (thsice) is now tested with testreport.
885    o test exp. advect_cs: use the standard cs32 grid ; update output.
886    o Added functionality to grdchk:
887      pick global i,j,k position (or nearest wet) where to perform check.
888    
889    checkpoint52l_post
890    o new land formulation:
891      a) use ground enthalpy as prognostic variable to ensure exact
892         energy conservation.
893      b) account for water temperature and for latent heat of freezing
894         in all processes (rain, run-off, ground storage)
895      c) compute surface and ground temperature implicitly.
896    o aim_v23 modification for new land model:
897      a) Treat separately land / ocean / sea-ice surface fluxes
898         to allow implicit computation of land & sea-ice surface temp.
899      b) add snow precipitation.
900    checkpoint52l_pre
901    
902    o fix problem (when 1 tile is empty) in min/max monitor.
903    o fix bug in timeAve (u,vZetatave in common block)
904    o no restoring terms under ice for pkg/seaice
905    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
906    o bug fix for pkg/seaice pickups
907    o change MNC call locations and add coordinate attributes
908    o mask vorticity at the corner ; affects global_ocean.cs output
909    o fix ini_curvilinear_grid ; test CS experiments with mpi
910    o aim.5l_cs: modify sea-ice fraction input file ; update output
911    o exf: Adding simple range check routine for exf fields after read
912    
913    checkpoint52k_post
914    o removed top-level directory "diags"
915      - we migrated these functions to pkg/timeave a long time ago
916    o fixed bug introduced in pkg/monitor
917    o accuracy ctrlprec = 32 insuffient for gradient checks using
918      averaged fields (I/O via cost_averages)
919      -> use ctrl.h in active_file*.F to control I/O precision.
920    o paramter list of CALL ADTHE_MAIN_LOOP
921    o added initial do_the_model_io to ecco
922    o set all ...Freq to zero after cost_final
923      taveFreq, dumpFreq, pChkptFreq
924    o MAIN and ECCO differentiability restored
925    
926    checkpoint52j_post
927    o fix nchklev in tamc.h for global_ocean...
928    o Bringing flow and store directives up-to-date
929    o Really weird thing!
930      call do_the_model_io from the_main_loop with parameters
931      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
932      TAF places a faulty re-call of initialise_varia
933      after cost_final call which should not be there!
934    checkpoint52j_pre
935    
936    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
937      error messages
938    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
939    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
940      debug output
941    o modfied mdsio_writefield.F to handle non-global files under exch2
942    o update AIM Cubed-Sphere exp (aim.5l_cs):
943      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
944    o update AIM Equatorial Channel exp:
945      use standard aim_v23 pkg and change the SST fields to be more realistic.
946    o globalFile now works with exch2
947    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
948      mon_vort3.F to make exch2 friendly with >1 tile per cube face
949    o limit timeave output for hi-res integrations
950    
951    checkpoint52i_post
952    o removed CPP_EEOPTIONS.h from verification/*/code
953    o updated the tiling for global_ocean_pressure
954    checkpoint52i_pre
955    
956    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
957      the old pkg/aim).
958    
959    checkpoint52h_pre
960    o shortened offending lines in exch2_send_rx?.template
961    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
962    o genmake2: add build & execute test for NetCDF code
963    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
964      old grid files, moved CPP_EEMACROS.h to pkg/exch2
965    o added useSingleCPUIO flag to monitor.F and mon_out.F
966    o added temporary hack for sea-ice dynamics on the cube:
967      metric terms are ignored and it is assumed that
968      there is no sea-ice on cube faces 1, 2, 4, and 5.
969    
970    checkpoint52f_post
971    o added exch2 cube routines to pkg/exch2
972    o modified hs94.cs-32x32x5 to use it
973    o added new grid files to hs94.cs-32x32x5
974    checkpoint52f_pre
975    
976    checkpoint52e_post
977    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
978      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
979    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
980      to work with implicit vertical advection and AB ;
981    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
982    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
983     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
984    checkpoint52e_pre
985    
986    o fix bug in impldiff when Nr=1 or Nr=2.
987    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
988    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
989    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
990      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
991    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
992    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
993    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
994    
995  checkpoint52d_post  checkpoint52d_post
996    o re-tiled many expts to allow comparison in multi-processor mode
997      - updated output accordingly
998      - changed hs94.128x64x5 to use intial T from file rather than use the
999        random number generator
1000    o add infrastructure in model routines for fizhi and gridalt packages
1001  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.
