5      ==============================      ==============================
6    
7    o reduce number of exch calls in shap_filt (s2).
8    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
9      truncation level) 4/5 MLAdjust test results (11&12 digits match).
10    
11    checkpoint57t_post
12    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
13    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
14      same truncation, independent of the face number: affects affects several
15      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
16    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
17      note that biharmonic viscosity + no-slip was not tested in any experiment.
18    o fix bug in non-linear free-surf side-drag ; generate new output for
19      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
20    o make mnc honor the writeBinaryPrec flag for most kinds of output
21    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
22    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
23      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
24    o add brackets in multi-terms sum to get same truncation, independent of
25      the face number (manage to get exactly same value of gU,gV at the cs-edge)
26      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
27    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
28      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
29      a maximum grid-scale Reynolds number.  Also, changes all length calculations
30      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
31      Suggested values of viscosity parameters found in mom_calc_visc.
32      Many new viscosity diagnostics available.
33    
34    checkpoint57s_post
35    o Add clearing-house for viscosity calculations, mom_calc_visc and
36      correct numerous bugs in LeithD and Smagorinsky discretizations.  
37      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
38      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
39      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
40      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
41      The Strain-Tension form is now called with useStrainTensonVisc=.true.
42      ViscAhStrain and viscAhTension are now retired.
43    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
44    o In response to JMC's bug report, genmake2 now ignores any soft-links
45      that it finds in the *current* directory when searching for files.
46      Soft-links found in any other source directories will still work as
47      they did before.
48    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
49      a C routine to unlimit the stack size
50    o mnc-ify pkg/aim snapshot vars
51    o mnc-ify pkg/land as requested by Daniel
52    o various changes to mnc including:
53      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
54      - output can now be grouped so that all files within a group
55          change the ITER portion of their names in lock-step together
56      - can now read ("global") PER-FACE (in addition to PER-TILE) files
57          and works with both EXCH1 and EXCH2 (but needs more testing)
58      - writing works for all verification test cases w/ g77 on Linux
59    
60    checkpoint57r_post
61    o make MNC variable initialization happen earlier
62    o add diagnostics for (almost) each term of the momentum Eq.
63    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
64    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
65    o remove MINIMAL_TAVE_OUTPUT option ;
66      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
67    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
68      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
69    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
70    o add time-dependent SST, SSS control
71    o cost terms in ecco/ modularized (new cost_generic.F)
72    o cost_averages routines are modularized (new cost_averagesgeneric.F)
73    o new infrastructure for seaice model vs. obs misfits in seaice/
74      * driver from the_main_loop.F is seaice_cost_driver.F
75      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
76      * gradient check in Exp. 6a of natl_box_adjoint/
77    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
78      (see README file)
79    
80    checkpoint57q_post
81    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
82    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
83      - bug was reported by Jean-Michel and Ian Fenty
84    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
85      update exp. cpl_aim+ocn output.
86    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
87      Needed for high-res. runs with large global files
88      to be able to limit tapelev size
89    o Changed some tests for adjoint:
90      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
91      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
92      * global_ocean.90x40x15/ back to default 3-level checkpointing
93    o Modifications to enable scripted COMMON to MODULE conversion
94      * verification/OpenAD/code/ has necessary scripts and description;
95      * converts, compiles and runs successfully;
96    
97    checkpoint57p_post
98    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
99    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
100      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
101    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
102    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
103      (was already the case for dissipation with mom_vecinv,
104       and also the case for grad.PhiHyd when staggered-timeStep)
105      This will allow to put dissipation out-off the AB time-stepping.
106     Unfortunately, affects truncation error. Update output of exp. that "fails"
107      (cg2d matching number) and leave the others for later: front_relax(10),
108      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
109      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
110    
111    checkpoint57o_post
112    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
113      (2) its ready to be documented during the 20050801 DocFest
114    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
115      for ideal_2D_oce and lab_sea on linux_ia32_g77
116    o set to #undef CTRL_SET_OLD_MAXCVARS_30
117      in global1x1_tot/code_seaice_adj to access indices 32, 33
118      (worth another tag)
119    
120    checkpoint57n_post
121    o adding precip control xx_precip 32
122    o adding swflux control xx_swflux 33
123    o Replacing 10 forcing penalty cost routines by 1 generic.
124    o Implementing partitioning in time-mean and variable adjustment
125      for atmos. state.
126    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
127    o in natl_box_adjoint:
128      * updated exp 1 to 10
129        (but does not have time-mean vs. variable split results yet)
130    o updated global1x1/*_seaice_adj/
131      to incorporate latest changes
132    o enable useSingleCpuIO for mdsio vector routines
133      (applies in particular to tapelev I/O)
134    o removed inefficient K-loop in all active_file*control*.F
135    
136    checkpoint57m_post
137    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
138      and advect_cs (use EXCH-2 and standard cs-32 grid files).
139    o pkg/exch2: filling of face-corner halo regions is optional
140      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
141    
142    checkpoint57l_post
143     tag before updating tutorials (pre-release-2)
144    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
145       for output and interpolation of input fields onto model grid)
146    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
147       Affects results of exp. rotating_tank ; update output.txt.
148    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
149          and taking the square quantity and/or using a fraction-weight field.
150    o fix aim_diagnostics_init.F mate numbers.
151    o add mnc output capability to diagnostics/diagstat and update
152      our cvsignore files for the ACSII output generated
153    
154    checkpoint57k_post
155    o lab_sea now uses diagnostics package and provides a suite of
156      new EXF diagnostics output.
157    
158    checkpoint57j_post
159    o exf
160      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
161        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
162        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
163      * extended diagnostics output
164        - now includes all EXF variables
165        - hs, hl moved to common block
166        - separate S/R for diagnostics, called after ctrl vector is added
167        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
168        - EXFqnet contains true Qnet (i.e. includes qsw)
169      * updated verif. lab_sea, global_with_exf
170      * Rearranging hflux (exf_mapfields -> exf_getforcing)
171        to ensure that diagnostics sees a true EXFqnet
172    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
173    o diagnostics pkg: change pointers so that 1 diagnostic can be used
174      several times with different frequencies.
175    o mnc-ify the thsice package as requested by Daniel Enderton
176      - the monitor--MNC output needs work
177      - many attributes need to be added (most are currently blank)
178    o mnc-ify theaim_v23 package as requested by Daniel Enderton
179      - many attributes need to be added (most are currently blank)
180    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
181    o add Sadourny like discretization to the 4th.O vorticity advection scheme
182    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
183      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
184         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
185    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
186     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
187    
188    checkpoint57i_post
189    o Diagnostics package was changed: diagnostic allocation is now deactivated
190      by setting an empty file name in the namelist (used to be by setting 0 frequency)
191    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
192      add 1rst Order upwind vertical Shear.
193    o add a quick fix for A/B checkpointing in OFFLINE mode
194    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
195      end-run around the C/Fortran linking horror in eesup/src/timers.F
196    o added pkg/runclock: allows user to terminate run based on wall clock
197    o added non-hydrostatic scaling parameter: nh_am2
198    o pkg/my82: futile attempt to make results compiler-independent by adding
199      some "_d 0", etc. no effect.
200    o for mnc output, fill the 'T' coordinate var with myTime and create a
201      separate 'iter' variable for iteration count
202    o pkg/diagnostics:
203      add new capability: output of Global/Regional & per-level statistics ;
204      tested against monitor output (including land & thSIce) on various exp.
205    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
206    
207    checkpoint57h_done
208      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
209      data.diagnostics, data.gchem, data.ptracers) is done.
210    
211    o pkg/diagnostics: prepare for Global/Regional statistics.
212      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
213    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
214      and rename it: DIFFERENT_MULTIPLE
215    
216    checkpoint57h_post
217    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
218    o pkg/diagnostics: change output frequency, now in seconds (instead
219      of Nb of iterations). This requires to change data.diagnostics.
220    checkpoint57h_pre
221    
222    o in mnc, let the user create the output dir if both mnc_outdir_date
223      and mnc_outdir_num are false
224    o add fflags() to pkg/diagnostics which allows one to specify, on a
225      per-file basis, the file precision [default behavior is unchanged]
226    o added diagnostics to pkg/kpp, including computation of mixed layer
227      depth based on a temperature/density criterion
228    o updated verification/natl_box to test the new pkg/kpp diagnostics
229    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
230    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
231    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
232      not mnc -- this mistake was found by JMC and is now corrected
233    
234    checkpoint57g_post
235    o add Adams-Bashforth 3rd Order time stepping:
236      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
237      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
238    checkpoint57g_pre
239    
240    o make lambda[Theta,Salt]ClimRelax spatially varying
241      (default remains spatially uniform constant based on tau)
242    o added new control variables
243      * init. uVel, vVel, etanN
244      * lambda[Theta,Salt]ClimRelax
245    o separate masks used for ctrl_pack/unpack 'from write_grid' output
246      (suggested by G. Forget)
247    
248    checkpoint57f_post
249    o add parameter "baseTime" = model base time = time at iteration zero
250      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
251      account for baseTime shift
252    o move Coriolis arrays from PARAMS.h to GRID.h
253    checkpoint57f_pre
254    
255    o mnc-ifying the seaice package
256    o introduced an alternative length scale calculation for use in the limiting
257      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
258    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
259    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
260      as well as grad(vort3).  Made it compatible with both approximate form
261      for the cubed sphere and full form of these gradients.  Added flag
262      useFullLeith to select between approximate and full form.  
263    o add "d0" in getcon.F to reduce differences between compilers/platforms
264      update output.txt of exp. fizhi-gridalt-hs
265    o change port_rand funtion to allow to set the seed.
266    o fix obscure MNC bug involving conversion between reals and integers
267      - it caused no problems with certain (eg. gcc, ifc) compilers but the
268        new version is now more standards-compliant
269    o adjoint-related modifications
270      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
271      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
272      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
273    
274    checkpoint57e_post
275    o Adding eddy stress controls a la Ferreira et al.
276    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
277    
278    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
279      update output.txt of exp. fizhi-gridalt-hs
280    o add more "Z" dimensions and associated coordinate vars to MNC
281    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
282    o parameter calendarDumps: when set, approximate months (30-31 days) and years
283      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
284      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
285      months and years.  Requires pkg/cal.
286    o diagnostics: add pickup functionality
287      - off by default for backwards compatibility
288      - current version only uses MDSIO -- MNC will be added
289    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
290    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
291    
292    checkpoint57d_post
293    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
294    o modify verification/ideal_2D_oce so that it tests the creation of mnc
295      output from the diagnostics package
296    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
297    o make genmake2 more portable by using ".$FS" instead of ".f" for more
298      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
299    o add coordinate variables to the MNC output from the diagnostics package
300    o change MNC-flags default value: true when useMNC=TRUE
301    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
302      the ability (off by default) to read the grid information using MNC
303    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
304    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
305    o do snap-shot diagnostics at the middle of the time-interval (instead of
306      at the end).
307    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
308      new test for AIM with thSIce + slab-ocean
309    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
310    o move state variable diagnostics to the beginning of the time step ;
311      (note: still needs some work specially for snap-shot diagnostics)
312      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
313    
314    checkpoint57c_post
315    o Change testing option (-ieee) to get closer agreement between g77 & ifort
316    o generate new output.txt files on faulks with g77 & the new -ieee option
317    checkpoint57c_pre
318    
319    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
320      update output.txt of exp. global_ocean.90x40x15
321    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
322      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
323    o add saltFlux(+File) forcing capability with periodicExternalForcing
324    o allow to use pkg diagnostics for GM-Redi & ThSIce output
325    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
326    o improvements for the MNC output from DIAGNOSTICS:
327      - correct handling of the unlimitied dimension
328      - all dims now have associated coordinate variables
329      - variables located at U, V, and Corner ("Z") points are now written
330        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
331        *all* data points are output
332    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
333    o added pkg/seaice/seaice_monitor.F
334    o mdsio_readfield.F can now read files visible only to master MPI process.
335    o pkg/seaice: some test code for ice-modified ocean stress
336    o exf_getffields interpolation defaults to bilinear for all scalar forcing
337      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
338      spurious negative numbers for precipitation and humidity.  Will cause
339      some small numerical differences for integrations using pkg/exf/exf_interp.F.
340    o pkg/ctrl/
341      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
342        May be enabled via doPackDiag
343      *  introduce z-scaling of
344         + gradient (doZscalePack) and
345         + control (doZscaleUnpack)
346    o pkg/mdsio/
347      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
348      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
349    
350    checkpoint57b_post
351    o simplify options in diagnostics_fill arguments (remove weird combinations)
352    o fix MNC coordinate variables so that they now contain per-face index
353      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
354      general, EXCH2 grids are only aligned to a "local" coordinate system
355    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
356    o Implement instantaneous output within pkg diagnostics:
357      setting a negative frequency in data.diagnostics produces
358     "snap-shot" output (as opposed to time-average if freq > 0)
359    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
360      NOTE: change ptracer diagnostics name: use 2 characters to work with
361            more than 9 tracers. Add also diagnostics of advect & diffus flux.
362    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
363      becomes the coordinate variable for the 'T' dimension
364    o add CF-style coordinate variables to MNC
365      - just a first cut:  numbers are meaningless on the cubesphere and
366        missing along the T axis but otherwise it works!
367    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
368    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
369    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
370      this is based directly on what the model compute, so that the content of
371      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
372    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
373    o clean up build options files for SunOS, in particular
374      - remove -traditional from xmakedepend
375      - change -xarch=v9 to -xarch=native for f77
376      - restore use of make (not gmake)
377      - add CC=gcc if using g77
378    o changes per discussion of AM, JMC, & EH3 today:
379      - move redundant "grid" variables out of "state" -- in preparation of
380        creating proper CF-style coordinate variables and in recognition
381        that any/all grid variables can be easily copied (eg. w/NCO) from
382        the grid files into any of the other NetCDF files
383      - *always* output grid variables with MDSIO (this will eventually be
384        changed)
385      - output MNC grid file if useMNC is true
386    o every instance of _END_MASTER() has been found and replaced with
387      _END_MASTER( myThid ) in order to satisfy certain picky Sun
388      preprocessors
389    o re-arrange diagnostics pkg initialisation:
390     - allow each package to extend the available diagnostics list
391     - add some checking and fix small problems (multi-threaded, ...)
392     - new S/R diagnostics_fill (replace fill_diagnostics):
393       look through the short list of active diag. (instead of the long list)
394       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
395    
396    checkpoint57a_post
397    o this set of changes restores TAMC compatibility
398      tested for global_ocean.90x40x15 adjoint on trough
399      (what a pain)
400    
401    checkpoint57a_pre
402    o some modifs in tools/build_options for sunos
403    o call ctrl_pack for ctrl at end for optimcycle=0
404    
405    checkpoint57
406    o add horizontal bi-harmonic viscosity for vertical velocity
407      - new parameter viscA4W (defaults to viscA4)
408      - affects only non-hydrostatic code
409      - to be done: no-slip lateral boundary conditions
410    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
411    o implement Implicit Vertical advection for pTracers
412    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
413      (implemented also for implicit vertical diffusion & advection)
414    o OBCS: extend application of tracer open boundary conditions
415      to a strip beyond the boundary of width Olx/Oly
416    o add call monitor to TAF set of required calls (flow directives)
417      and include in natl_box_adjoint
418    o untangle a few ifdefs related to cost, ctrl, autodiff
419      untangel a few ALLOW_ECCO_OPTIMIZATION
420    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
421      (theta2, salt2 in ecco_cost_weights)
422    
423    checkpoint56c_post
424    o OBCS as control variables
425      - update ctrl_ad_diff.list, obcs_ad_diff.list
426      - remove balance of obcs controls from default
427      - fix index bug nobcs in ctrl_init
428      - fix dummy fields filen in ctrl_pack
429      - add dummy weights for obcs
430    o lsopt: comment out fort.94 output
431    o optim:
432      - remove unnecessary header files
433      - adjusted namelists
434      - add xerbla.F to Makefile
435    o exf:
436      - multiple modifications of exf_check_range
437      - unit change in exf_init_runoff from [m/year] to [m/s]
438    o mdsio:
439      - i/o-vector change debugLevel from debLevA to debLevB
440    
441    checkpoint56b_post
442    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
443      is called from DO_THE_MODEL_IO
444      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
445      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
446      - clean up PTRACERS_WRITE_TIMEAVE a little
447    o add another verification experiment that tests both the cfc-pkg and
448      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
449      reactive tendencies treated inline with regular timestepping
450    o testreport previously did a lousy job of comparing small numbers, so
451      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
452      implemented in the little c-progam tmp_cmpnum.c which is embedded in
453      testreport.
454    o ptracers_monitor: bug fix for MPI
455    
456    checkpoint56a_post
457    o GCHEM: finish reorganizating the package
458      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
459        (introduces another 3D-array for each passive tracer, but only if
460        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
461        gchemTendency is not needed because the timestep is done separately)
462      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
463      - GCHEM is now---more or less cleanly---separate from PTRACERS
464      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
465        so clear to me how that should be done in a general way.
466    o CFC: improve formatting of output in CFC_ATMOS
467    o PTRACERS:
468      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
469        that ALL experiments with ptracers enable can be checked. This makes
470        GCHEM_MONITOR obsolete.
471      - include a runtime parameter PTRACERS_monitorFreq that defaults to
472        monitorFreq
473      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
474    o add PTRACERS (PTR0[1-5]) to testreport output
475    o exf_check_range:
476      * default changed to .TRUE.
477      * will check values for niter0 if debLevA, every timestep if debLevB
478      * STOP in exf_check_range if 'out of range'
479      * range chosen generous to allow for potential extema
480      TBD: a version with stricter range
481           permitted range would be runtime parameters
482    o GMredi:
483      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
484      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
485      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
486    o GCHEM:
487      - move call to GCHEM_FORCING_SEP, so that it is now called before
488        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
489      - introduced a useGCHEM runtime flag and applied it everywhere.
490      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
491        this flag is now only visible within GCHEM-pkg routines.
492      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
493        be replaced by a 3D array that is computed before thermodynamics; for
494        this, the tracer ID iTracer had to be included into the parameter list
495        of ptracers_forcing
496      - set up forward_step to call gchem_forcing, that will replace
497        gchem_forcing_int in ptracers_forcing
498      - cleaning up
499    o small cleaning of exch2: remove files that are also in eesupp/src
500    
501    checkpoint56
502    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
503    o mnc: cleanup "full" files--fixes out-of-memory problem
504    o ECCO-GODAE
505      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
506      * fully merged and updated from SIO code
507        windstress sign change affects
508        - exf_inscal_[u/v]stress
509        - sign of xx_tau[u/v] adjustments
510        - signs in cost_scat
511      * ctrl_get_gen: avoid update of tau[u/v] for first few days
512      * natl_box_adjoint updated and compressed
513      * 2-level checkpoint switch added
514        (tested in EXP. 1 of natl_box_adjoint)
515      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
516    o SVD
517      * first complete, non-hacked version for SVD calculations
518      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
519        performed via direct access files admtlm_vector.it????
520        (via ctrl_[un]pack)
521      * optimcycle is used for ARPACK iteration counter
522        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
523      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
524        and add linear transforms where necessary
525      * controls are initial/final SST, SSS (can be extended; need to check
526        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
527    o mdsio: filename info to both stderr, stdout
528    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
529      from sign change
530    
531    checkpoint55j_post
532    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
533      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
534    o add consistent build directories and .cvsignore files to verification
535    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
536    o make all subroutines 30 or less characters in length for certain older
537      compilers to work (a thorough search only turns up two routines in
538      pkg/ptracers)
539    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
540      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
541    
542    checkpoint55i_post
543    o change arrays for total vertical diffusivity (2.D if explicit,
544      3.D if implicit) ; each ptracer uses its own background value.
545    o added mnc/NetCDF output capability to ocn_compon_interf
546      - added bits to verification/cpl_aim+ocn so that it can run on
547        ITRDA and other clusters without the mpirun "-wd" option
548    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
549      configuration
550    o give MNC the ability to create additional files rather than
551      exceeding a specified file size limit "MNC_MAX_FILESIZE"
552      - the default is just less than 2GB which is a practical limit
553        on many systems
554    o Compute the non-local term using either KPP vertical diffusivity (=default)
555       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
556    
557    checkpoint55h_post
558    o add verification test "vermix"
559    o remove all the *_ioinc flags and replace with the single global
560      outputTypesInclusive flag
561    o allow to set a vertical profile of vertical diffusivity for T & S
562    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
563    o useMNC moved from data.mnc to data.pkg
564    
565    checkpoint55g_post
566    o Renaming carbon AD experiments to comply with testreport conventions
567    o Updating adjoint of Held-Suarez hs94.1x64x5
568    o Fixing directives for non-ECCO forward_step, after ECCO directives
569      have been fixed to avoid recomp. of do_oceanic_phys
570      Works well for global_ocean.90x40x15,
571      but recomp. issue remains for carbon
572    o Updating adjoint output for natl_box_adjoint after
573      pkg/ecco has been modified (see taga c55d_post)
574    
575    checkpoint55f_post
576    o rename to timeave_init_fixed
577    
578    checkpoint55e_post
579    o some delicate re-shuffle of store directives to avoid one
580      extra call of do_oceanic_physics
581      affects ecco_the_main_loop.F, do_oceanic_physics.F
582      checkpoint_lev1_directives.h
583    o NB: this may break global_ocean adjoint temporarily,
584      but it is clear how to fix it. Will do later, need this now.
585    
586    checkpoint55d_post
587    o ECCO specific cost function terms (up-to-date with 1x1 runs)
588    o ecco_cost_weights is modified to 1x1 runs
589    o modifs to allow observations to be read in as
590      single file or yearly files
591    o enable to read exf forcing fields as either
592      single file or yearly files (flag useExfYearlyFields)
593    checkpoint55d_pre
594    
595    o switch between 2-level and 3-level checkpointing
596    o add ability of MNC to write local and "partial" (eg. 2D slices where
597      the full 3D field is never actually stored) arrays to NetCDF files
598      with the correct (that is, the complete multi-dimensional) set of
599      array indicies
600      - used in mom_vecinv() to write the diagFreq output
601      - tested (demonstrated) in verification/aim.5l_cs
602    o further mnc-ification
603      - add verification/lab_sea to the list with mnc setups
604      - fix undefined mnc v-names in cd_code
605      - add kpp to mnc output (both snapshot and timeave)
606    o non-hydrostatic code
607      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
608        in calc_gw.F
609      - defaults to viscAh
610      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
611        friction or Leith) in non-hydrostatic mode, as long as there is
612        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
613    o pkg/cost
614      extend simple cost functions to treat time mean quantities
615      (T,U,V) via cost_accumulate_state from cost_tile
616    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
617        be 2 times larger than the minimum size the advection scheme requires.
618        now get a perfect conservation of salt in advect_cs test-exp (updated)
619    o GGL90 (Gaspar's TKE mixed layer)
620      - add horizontal diffusion of TKE, requires exchanges in
621        do_fields_blocking_exchanges, horizontal diffusivity is zero by
622        default. In OPA there is no horizontal diffusion of TKE but the
623        mixing coefficients are computed from a horizontal average of TKE of
624        6 points or so. I think that diffusion has a little more physical
625        justification.
626      - clean up ggl90_calc in the hope of reducing memory usage (this hope
627        was in vain)
628      - mask tke-variable in ggl90_init
629    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
630    o fix biharmonic diffusion on CS-grid.
631    o more obcs stuff
632      - added obcs_external_fields_load as an alternative to the EXF-pkg option
633        for reading boundary values. This routine is called from
634        obcs_prescribe_read
635      - updated obcs_check
636      - changed sponge layer relaxation parameter units for days to seconds
637      - turned off sponge layer by default
638      - changed argument list of OBCS_CALC to myTime+deltaTclock
639      - fixed about 35 bugs in obcs_external_fields_load
640    
641    checkpoint55c_post
642    o obcs stuff
643      - new runtime flags useOBCSprescribe, useOBCSbalance
644      - re-arranged obcs_calc
645      - moved exf_getobcs to obcs_prescibe_read
646        obcs_prescibe_read is called after ORLANSKI stuff
647        and independent of it (executable can contain all).
648      - updated obcs_check
649      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
650        These may be necessary only if tangential velocities are
651        prescribed at OB, not sure, needs testing.
652    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
653      which simplifies the calls and passes the ifc check-bounds test
654    
655    checkpoint55b_post
656    o add a 2D scalar, Z location, exchange_2 routine.
657    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
658      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
659      affects advect_cs results (for the wrong reason): update output.txt
660    o use a more standard discretization for biharmonic viscosity ;
661     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
662      affects results of dome set-up: update output.txt
663    o fix gad_advection.F (CubedSphere part), back to version 1.23
664    o fix bug in mom_vi_del2uv.F (CubedSphere part).
665    
666    checkpoint55a_post
667    o merged code to
668      * prescribe/read time-dependent open boundaries
669        (works in conjunction with exf, cal)
670      * sponge layer code for open boundaries
671      * each boundary N/S/E/W now has its own CPP option
672        (healthy for the adjoint)
673    
674    checkpoint55
675    o up-to-date adjoint of previous breaks
676      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
677      - global_ocean_ebm: adjoint still needs fix (TLM ok)
678      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
679      - carbon: * remove tr1-related adjoint verification
680                * add ptracer as control variable
681    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
682      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
683    
684    checkpoint54f_post
685    o in verification/carbin/ remove experiment related to
686      ALLOW_PASSIVE_TRACER (array tr1 etc)
687      code_ad/ input_ad/ results_ad
688    
689    o add two new packages
690      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
691        + subject to optimization (memory)
692      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
693        + subject to reordering (many GOTOs in the original code)
694        + so far opps is called for every (i,j) point, and then operates in
695          the vertical; one may want to reorder the scheme in order operate in
696          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
697          fields)
698    o overhaul of IO so that we now have flags for MDSIO and/or MNC
699      - all verification tests compile and run with linux_ia32_g77
700      - defaults are compatible with current input files--nothing
701        should change if you were not previously using MNC
702      - MNC output has been added in numerous places (eg. timeave)
703        but there are still a few writes not yet do-able with MNC
704        (this is in progress)
705      - flags now allow for either/or/both use of MDSIO and MNC and
706        documentation will soon follow
707      - numerous small formatting cleanups for ProTeX
708    o add version info (via BUILD_INFO.h) to MNC and stdout
709    
710    checkpoint54e_post
711    o add two new packages
712      - pp81 (Packanowski and Philander, 1981), Richardson number and
713        stratification dependent mixing
714      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
715      - these scheme operate in a similar manner as KPP (without ghat, of
716        course), however there is only one diffusivity that is used for both
717        temperature and salinity (and passive tracers)ç
718    o add offline package
719    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
720      provided by Stephanie Dutkiewicz
721    o genmake2: add ability to search for C compilers and cleanup test output
722      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
723    
724    checkpoint54d_post
725    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
726    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
727      leading to additional shift by 5 days each year of integration
728       (i.e. leading to considerable offset over the years)
729    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
730    o start with no AB and no initial filtering (staggerTimeStep):
731      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
732    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
733      (external loading & cpl import/export stay in forward_step.F)
734    o update coupling interface to work with new staggerTimeStep
735    o change MDSIO ptracers_pickup.
736    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
737    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
738    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
739    
740    checkpoint54c_post
741    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
742      this affects (truncation error) output.txt of test-exp:
743       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
744    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
745    o change Qnet to always be the net heat flux, (+upward).
746      affects (truncation error) output of natl_box exp.: updated
747    o define the max number of passive tracers in PTRACERS_SIZE.h
748    o start to test mnc routinely in exp0
749    o add sea-ice loading (sIceLoad) as a new forcing field.
750    
751    checkpoint54b_post
752    o add testreport "-j JOBS" option for parallel builds (tested and pretty
753       impressive on Altix and Opteron systems)
754    o diagnostics can now write NetCDF files through the mnc package
755    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
756    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
757    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
758      affects (truncation error) output of lab_sea & natl_box exp.: updated
759    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
760    
761    checkpoint54a_post
762    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
763    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
764    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
765    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
766      + internal_wave (shift in writing cg2d_ini_res)
767    checkpoint54a_pre
768    
769    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
770      - modified verification/lab_sea and natl_box_adjoint accordingly
771    
772    checkpoint54
773    checkpoint53g_post
774    o prepare splitting of thermodynamics: store convect.counter in common block
775    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
776      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
777    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
778    o new parameter "nShapS": allow to treat differently S from T (nShapT)
779    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
780    o restore adjointability
781    
782    checkpoint53f_post
783    o modifications that affect AIM experiment results (update output.txt):
784      - no advection of S at top interface Nr (pkg/generic_advdiff)
785      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
786    o AIM pkg:
787      - include stability function into surf.Flux derivative relative to Tsurf
788      - calculate clear-sky radiation & surface temp. change (for diagnostics)
789    
790    checkpoint53e_post
791    o merged cylindrical coord configuration
792    o added rotating_tank experiment
793    checkpoint53e_pre
794    
795    checkpoint53d_post
796    o faulks upgraded: re-generate output.txt that have changed:
797       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
798    o Added Bryan and Lewis, 1979, vertical diffusivity profile
799    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
800    o added Sadourny discretization of Coriolis
801      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
802      - re-enabled use of omega3 (useAbsVorticity)
803    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
804      vector-invariant equations
805      - note: does *NOT* yet use same variable visc. for no-slip BC's.
806    o recoded the lateral boundary conditions for non-hydrostatic w, this time
807      hopefully without new bugs
808      - still to do: biharmonic friction for non-hydrostatic w
809    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
810    o regenerated output for global_ocean_ebm (using -ieee)
811    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
812      of mom_common/
813      - simple re-arrangement of instructions within computing loop
814    checkpoint53d_pre
815    
816    checkpoint53c_post
817    o new version of coupler for AIM+thSIce and Ocean models
818     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
819     - land: change Evaporation of snow
820     - aim with thSIce: fix bug in snow-precip.
821    o changes to calc_gw.F
822     - bug fix for w^2 term near the bottom boundary
823     - (hopefully) improve the lateral slip boundary condtions for use with
824        partial/looped cells
825      - because the bug fix changes two verification experiments anyway (exp5
826        and plume on slope), change the lateral boundary condition from half slip
827        to the value of no_slip_sides
828    o ebm package wasnt quite up to the parallel task. Fixed that.
829    o Adjoint of EBM package + verification
830      * TLM OK
831      * ADM not sufficient accuracy yet (needs further testing)
832    
833    checkpoint53b_post
834    o Commiting new energy balance model to repository
835      * package is pkg/ebm
836      * verif. is verification/global_ocean_ebm
837      * references are in ebm_driver.F
838    C      * X. Wang, P. Stone and J. Marotzke, 1999:
839    C        Global thermohaline circulation. Part I:
840    C        Sensitivity to atmospheric moisture transport.
841    C        J. Climate 12(1), 71-82
842    C      * X. Wang, P. Stone and J. Marotzke, 1999:
843    C        Global thermohaline circulation. Part II:
844    C        Sensitivity with interactive transport.
845    C        J. Climate 12(1), 83-91
846    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
847    C        Destabilization of the thermohaline circulation
848    C        by atmospheric eddy transports.
849    C        J. Climate 7(12), 1870-1882
850    o Will need long integration testing.
851    checkpoint53b_pre
852    
853    o created pkg/mom_common in preparation for variable viscosity code
854    o renamed and split ini_mnc_io
855    o pkg/land: only liquid water can diffuse or run-off
856    o AIM using land: soil wetness availability account for snow
857    o added printMapIncludesZeros to EEPARMS namelist
858    
859    checkpoint53a_post
860    o restore TAMC compatiility for exf_constants.h
861      (no usage of _d in .h)
862    o Additional storing in KPP in an attempt to fix
863      TAMC problem with adjoint of KPP code.
864      (no success...)
865      Identical code works fine with TAF.
866    o Fixed verification/natl_box_adjoint experiments.
867      Initial conditions for Experiments 4 and 5 are now
868      set to "SEAICE_initialHEFF=0", which is more reasonable,
869      and hence gives results closer to that of Experiment 2.
870      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
871    
872    checkpoint53
873    o stable checkpoint with up to date adjoint
874      TLM tests only run for 1st grdchk at the moment. Its unclear if
875      this is a code problem or a problem with resetting code for g_
876      variables that is being autogenerated wrong.
877      Otherwise:
878       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
879       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
880         are both still in chaos following their security messes.
881    
882    checkpoint52n_post
883    o various build (mostly genmake2) changes including:
884      - ability to build/run more easily within Cygwin and MacOS X
885      - more complicated Makefiles with a stronger dependence on Gnu Make
886  o pkg/seaice modifications  o pkg/seaice modifications
887    - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost    - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
888      of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer      of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
