5      ==============================      ==============================
6    
7    o mnc-ify aim_v23 as requested by Daniel Enderton
8    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
9    o add Sadourny like discretization to the 4th.O vorticity advection scheme
10    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
11      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
12         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
13    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
14     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
15    
16    checkpoint57i_post
17    o Diagnostics package was changed: diagnostic allocation is now deactivated
18      by setting an empty file name in the namelist (used to be by setting 0 frequency)
19    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
20      add 1rst Order upwind vertical Shear.
21    o add a quick fix for A/B checkpointing in OFFLINE mode
22    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
23      end-run around the C/Fortran linking horror in eesup/src/timers.F
24    o added pkg/runclock: allows user to terminate run based on wall clock
25    o added non-hydrostatic scaling parameter: nh_am2
26    o pkg/my82: futile attempt to make results compiler-independent by adding
27      some "_d 0", etc. no effect.
28    o for mnc output, fill the 'T' coordinate var with myTime and create a
29      separate 'iter' variable for iteration count
30    o pkg/diagnostics:
31      add new capability: output of Global/Regional & per-level statistics ;
32      tested against monitor output (including land & thSIce) on various exp.
33    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
34    
35    checkpoint57h_done
36      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
37      data.diagnostics, data.gchem, data.ptracers) is done.
38    
39    o pkg/diagnostics: prepare for Global/Regional statistics.
40      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
41    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
42      and rename it: DIFFERENT_MULTIPLE
43    
44    checkpoint57h_post
45    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
46    o pkg/diagnostics: change output frequency, now in seconds (instead
47      of Nb of iterations). This requires to change data.diagnostics.
48    checkpoint57h_pre
49    
50    o in mnc, let the user create the output dir if both mnc_outdir_date
51      and mnc_outdir_num are false
52    o add fflags() to pkg/diagnostics which allows one to specify, on a
53      per-file basis, the file precision [default behavior is unchanged]
54    o added diagnostics to pkg/kpp, including computation of mixed layer
55      depth based on a temperature/density criterion
56    o updated verification/natl_box to test the new pkg/kpp diagnostics
57    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
58    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
59    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
60      not mnc -- this mistake was found by JMC and is now corrected
61    
62    checkpoint57g_post
63    o add Adams-Bashforth 3rd Order time stepping:
64      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
65      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
66    checkpoint57g_pre
67    
68    o make lambda[Theta,Salt]ClimRelax spatially varying
69      (default remains spatially uniform constant based on tau)
70    o added new control variables
71      * init. uVel, vVel, etanN
72      * lambda[Theta,Salt]ClimRelax
73    o separate masks used for ctrl_pack/unpack 'from write_grid' output
74      (suggested by G. Forget)
75    
76    checkpoint57f_post
77    o add parameter "baseTime" = model base time = time at iteration zero
78      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
79      account for baseTime shift
80    o move Coriolis arrays from PARAMS.h to GRID.h
81    checkpoint57f_pre
82    
83    o mnc-ifying the seaice package
84    o introduced an alternative length scale calculation for use in the limiting
85      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
86    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
87    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
88      as well as grad(vort3).  Made it compatible with both approximate form
89      for the cubed sphere and full form of these gradients.  Added flag
90      useFullLeith to select between approximate and full form.  
91    o add "d0" in getcon.F to reduce differences between compilers/platforms
92      update output.txt of exp. fizhi-gridalt-hs
93    o change port_rand funtion to allow to set the seed.
94    o fix obscure MNC bug involving conversion between reals and integers
95      - it caused no problems with certain (eg. gcc, ifc) compilers but the
96        new version is now more standards-compliant
97    o adjoint-related modifications
98      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
99      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
100      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
101    
102    checkpoint57e_post
103    o Adding eddy stress controls a la Ferreira et al.
104    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
105    
106    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
107      update output.txt of exp. fizhi-gridalt-hs
108    o add more "Z" dimensions and associated coordinate vars to MNC
109    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
110    o parameter calendarDumps: when set, approximate months (30-31 days) and years
111      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
112      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
113      months and years.  Requires pkg/cal.
114    o diagnostics: add pickup functionality
115      - off by default for backwards compatibility
116      - current version only uses MDSIO -- MNC will be added
117    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
118    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
119    
120    checkpoint57d_post
121    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
122    o modify verification/ideal_2D_oce so that it tests the creation of mnc
123      output from the diagnostics package
124    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
125    o make genmake2 more portable by using ".$FS" instead of ".f" for more
126      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
127    o add coordinate variables to the MNC output from the diagnostics package
128    o change MNC-flags default value: true when useMNC=TRUE
129    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
130      the ability (off by default) to read the grid information using MNC
131    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
132    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
133    o do snap-shot diagnostics at the middle of the time-interval (instead of
134      at the end).
135    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
136      new test for AIM with thSIce + slab-ocean
137    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
138    o move state variable diagnostics to the beginning of the time step ;
139      (note: still needs some work specially for snap-shot diagnostics)
140      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
141    
142    checkpoint57c_post
143    o Change testing option (-ieee) to get closer agreement between g77 & ifort
144    o generate new output.txt files on faulks with g77 & the new -ieee option
145    checkpoint57c_pre
146    
147    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
148      update output.txt of exp. global_ocean.90x40x15
149    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
150      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
151    o add saltFlux(+File) forcing capability with periodicExternalForcing
152    o allow to use pkg diagnostics for GM-Redi & ThSIce output
153    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
154    o improvements for the MNC output from DIAGNOSTICS:
155      - correct handling of the unlimitied dimension
156      - all dims now have associated coordinate variables
157      - variables located at U, V, and Corner ("Z") points are now written
158        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
159        *all* data points are output
160    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
161    o added pkg/seaice/seaice_monitor.F
162    o mdsio_readfield.F can now read files visible only to master MPI process.
163    o pkg/seaice: some test code for ice-modified ocean stress
164    o exf_getffields interpolation defaults to bilinear for all scalar forcing
165      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
166      spurious negative numbers for precipitation and humidity.  Will cause
167      some small numerical differences for integrations using pkg/exf/exf_interp.F.
168    o pkg/ctrl/
169      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
170        May be enabled via doPackDiag
171      *  introduce z-scaling of
172         + gradient (doZscalePack) and
173         + control (doZscaleUnpack)
174    o pkg/mdsio/
175      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
176      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
177    
178    checkpoint57b_post
179    o simplify options in diagnostics_fill arguments (remove weird combinations)
180    o fix MNC coordinate variables so that they now contain per-face index
181      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
182      general, EXCH2 grids are only aligned to a "local" coordinate system
183    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
184    o Implement instantaneous output within pkg diagnostics:
185      setting a negative frequency in data.diagnostics produces
186     "snap-shot" output (as opposed to time-average if freq > 0)
187    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
188      NOTE: change ptracer diagnostics name: use 2 characters to work with
189            more than 9 tracers. Add also diagnostics of advect & diffus flux.
190    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
191      becomes the coordinate variable for the 'T' dimension
192    o add CF-style coordinate variables to MNC
193      - just a first cut:  numbers are meaningless on the cubesphere and
194        missing along the T axis but otherwise it works!
195    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
196    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
197    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
198      this is based directly on what the model compute, so that the content of
199      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
200    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
201    o clean up build options files for SunOS, in particular
202      - remove -traditional from xmakedepend
203      - change -xarch=v9 to -xarch=native for f77
204      - restore use of make (not gmake)
205      - add CC=gcc if using g77
206    o changes per discussion of AM, JMC, & EH3 today:
207      - move redundant "grid" variables out of "state" -- in preparation of
208        creating proper CF-style coordinate variables and in recognition
209        that any/all grid variables can be easily copied (eg. w/NCO) from
210        the grid files into any of the other NetCDF files
211      - *always* output grid variables with MDSIO (this will eventually be
212        changed)
213      - output MNC grid file if useMNC is true
214    o every instance of _END_MASTER() has been found and replaced with
215      _END_MASTER( myThid ) in order to satisfy certain picky Sun
216      preprocessors
217    o re-arrange diagnostics pkg initialisation:
218     - allow each package to extend the available diagnostics list
219     - add some checking and fix small problems (multi-threaded, ...)
220     - new S/R diagnostics_fill (replace fill_diagnostics):
221       look through the short list of active diag. (instead of the long list)
222       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
223    
224    checkpoint57a_post
225    o this set of changes restores TAMC compatibility
226      tested for global_ocean.90x40x15 adjoint on trough
227      (what a pain)
228    
229    checkpoint57a_pre
230    o some modifs in tools/build_options for sunos
231    o call ctrl_pack for ctrl at end for optimcycle=0
232    
233    checkpoint57
234    o add horizontal bi-harmonic viscosity for vertical velocity
235      - new parameter viscA4W (defaults to viscA4)
236      - affects only non-hydrostatic code
237      - to be done: no-slip lateral boundary conditions
238    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
239    o implement Implicit Vertical advection for pTracers
240    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
241      (implemented also for implicit vertical diffusion & advection)
242    o OBCS: extend application of tracer open boundary conditions
243      to a strip beyond the boundary of width Olx/Oly
244    o add call monitor to TAF set of required calls (flow directives)
245      and include in natl_box_adjoint
246    o untangle a few ifdefs related to cost, ctrl, autodiff
247      untangel a few ALLOW_ECCO_OPTIMIZATION
248    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
249      (theta2, salt2 in ecco_cost_weights)
250    
251    checkpoint56c_post
252    o OBCS as control variables
253      - update ctrl_ad_diff.list, obcs_ad_diff.list
254      - remove balance of obcs controls from default
255      - fix index bug nobcs in ctrl_init
256      - fix dummy fields filen in ctrl_pack
257      - add dummy weights for obcs
258    o lsopt: comment out fort.94 output
259    o optim:
260      - remove unnecessary header files
261      - adjusted namelists
262      - add xerbla.F to Makefile
263    o exf:
264      - multiple modifications of exf_check_range
265      - unit change in exf_init_runoff from [m/year] to [m/s]
266    o mdsio:
267      - i/o-vector change debugLevel from debLevA to debLevB
268    
269    checkpoint56b_post
270    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
271      is called from DO_THE_MODEL_IO
272      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
273      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
274      - clean up PTRACERS_WRITE_TIMEAVE a little
275    o add another verification experiment that tests both the cfc-pkg and
276      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
277      reactive tendencies treated inline with regular timestepping
278    o testreport previously did a lousy job of comparing small numbers, so
279      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
280      implemented in the little c-progam tmp_cmpnum.c which is embedded in
281      testreport.
282    o ptracers_monitor: bug fix for MPI
283    
284    checkpoint56a_post
285    o GCHEM: finish reorganizating the package
286      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
287        (introduces another 3D-array for each passive tracer, but only if
288        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
289        gchemTendency is not needed because the timestep is done separately)
290      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
291      - GCHEM is now---more or less cleanly---separate from PTRACERS
292      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
293        so clear to me how that should be done in a general way.
294    o CFC: improve formatting of output in CFC_ATMOS
295    o PTRACERS:
296      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
297        that ALL experiments with ptracers enable can be checked. This makes
298        GCHEM_MONITOR obsolete.
299      - include a runtime parameter PTRACERS_monitorFreq that defaults to
300        monitorFreq
301      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
302    o add PTRACERS (PTR0[1-5]) to testreport output
303    o exf_check_range:
304      * default changed to .TRUE.
305      * will check values for niter0 if debLevA, every timestep if debLevB
306      * STOP in exf_check_range if 'out of range'
307      * range chosen generous to allow for potential extema
308      TBD: a version with stricter range
309           permitted range would be runtime parameters
310    o GMredi:
311      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
312      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
313      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
314    o GCHEM:
315      - move call to GCHEM_FORCING_SEP, so that it is now called before
316        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
317      - introduced a useGCHEM runtime flag and applied it everywhere.
318      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
319        this flag is now only visible within GCHEM-pkg routines.
320      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
321        be replaced by a 3D array that is computed before thermodynamics; for
322        this, the tracer ID iTracer had to be included into the parameter list
323        of ptracers_forcing
324      - set up forward_step to call gchem_forcing, that will replace
325        gchem_forcing_int in ptracers_forcing
326      - cleaning up
327    o small cleaning of exch2: remove files that are also in eesupp/src
328    
329    checkpoint56
330    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
331    o mnc: cleanup "full" files--fixes out-of-memory problem
332    o ECCO-GODAE
333      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
334      * fully merged and updated from SIO code
335        windstress sign change affects
336        - exf_inscal_[u/v]stress
337        - sign of xx_tau[u/v] adjustments
338        - signs in cost_scat
339      * ctrl_get_gen: avoid update of tau[u/v] for first few days
340      * natl_box_adjoint updated and compressed
341      * 2-level checkpoint switch added
342        (tested in EXP. 1 of natl_box_adjoint)
343      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
344    o SVD
345      * first complete, non-hacked version for SVD calculations
346      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
347        performed via direct access files admtlm_vector.it????
348        (via ctrl_[un]pack)
349      * optimcycle is used for ARPACK iteration counter
350        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
351      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
352        and add linear transforms where necessary
353      * controls are initial/final SST, SSS (can be extended; need to check
354        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
355    o mdsio: filename info to both stderr, stdout
356    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
357      from sign change
358    
359    checkpoint55j_post
360    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
361      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
362    o add consistent build directories and .cvsignore files to verification
363    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
364    o make all subroutines 30 or less characters in length for certain older
365      compilers to work (a thorough search only turns up two routines in
366      pkg/ptracers)
367    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
368      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
369    
370    checkpoint55i_post
371    o change arrays for total vertical diffusivity (2.D if explicit,
372      3.D if implicit) ; each ptracer uses its own background value.
373    o added mnc/NetCDF output capability to ocn_compon_interf
374      - added bits to verification/cpl_aim+ocn so that it can run on
375        ITRDA and other clusters without the mpirun "-wd" option
376    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
377      configuration
378    o give MNC the ability to create additional files rather than
379      exceeding a specified file size limit "MNC_MAX_FILESIZE"
380      - the default is just less than 2GB which is a practical limit
381        on many systems
382    o Compute the non-local term using either KPP vertical diffusivity (=default)
383       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
384    
385    checkpoint55h_post
386    o add verification test "vermix"
387    o remove all the *_ioinc flags and replace with the single global
388      outputTypesInclusive flag
389    o allow to set a vertical profile of vertical diffusivity for T & S
390    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
391    o useMNC moved from data.mnc to data.pkg
392    
393    checkpoint55g_post
394    o Renaming carbon AD experiments to comply with testreport conventions
395    o Updating adjoint of Held-Suarez hs94.1x64x5
396    o Fixing directives for non-ECCO forward_step, after ECCO directives
397      have been fixed to avoid recomp. of do_oceanic_phys
398      Works well for global_ocean.90x40x15,
399      but recomp. issue remains for carbon
400    o Updating adjoint output for natl_box_adjoint after
401      pkg/ecco has been modified (see taga c55d_post)
402    
403    checkpoint55f_post
404    o rename to timeave_init_fixed
405    
406    checkpoint55e_post
407    o some delicate re-shuffle of store directives to avoid one
408      extra call of do_oceanic_physics
409      affects ecco_the_main_loop.F, do_oceanic_physics.F
410      checkpoint_lev1_directives.h
411    o NB: this may break global_ocean adjoint temporarily,
412      but it is clear how to fix it. Will do later, need this now.
413    
414    checkpoint55d_post
415    o ECCO specific cost function terms (up-to-date with 1x1 runs)
416    o ecco_cost_weights is modified to 1x1 runs
417    o modifs to allow observations to be read in as
418      single file or yearly files
419    o enable to read exf forcing fields as either
420      single file or yearly files (flag useExfYearlyFields)
421    checkpoint55d_pre
422    
423    o switch between 2-level and 3-level checkpointing
424    o add ability of MNC to write local and "partial" (eg. 2D slices where
425      the full 3D field is never actually stored) arrays to NetCDF files
426      with the correct (that is, the complete multi-dimensional) set of
427      array indicies
428      - used in mom_vecinv() to write the diagFreq output
429      - tested (demonstrated) in verification/aim.5l_cs
430    o further mnc-ification
431      - add verification/lab_sea to the list with mnc setups
432      - fix undefined mnc v-names in cd_code
433      - add kpp to mnc output (both snapshot and timeave)
434    o non-hydrostatic code
435      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
436        in calc_gw.F
437      - defaults to viscAh
438      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
439        friction or Leith) in non-hydrostatic mode, as long as there is
440        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
441    o pkg/cost
442      extend simple cost functions to treat time mean quantities
443      (T,U,V) via cost_accumulate_state from cost_tile
444    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
445        be 2 times larger than the minimum size the advection scheme requires.
446        now get a perfect conservation of salt in advect_cs test-exp (updated)
447    o GGL90 (Gaspar's TKE mixed layer)
448      - add horizontal diffusion of TKE, requires exchanges in
449        do_fields_blocking_exchanges, horizontal diffusivity is zero by
450        default. In OPA there is no horizontal diffusion of TKE but the
451        mixing coefficients are computed from a horizontal average of TKE of
452        6 points or so. I think that diffusion has a little more physical
453        justification.
454      - clean up ggl90_calc in the hope of reducing memory usage (this hope
455        was in vain)
456      - mask tke-variable in ggl90_init
457    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
458    o fix biharmonic diffusion on CS-grid.
459    o more obcs stuff
460      - added obcs_external_fields_load as an alternative to the EXF-pkg option
461        for reading boundary values. This routine is called from
462        obcs_prescribe_read
463      - updated obcs_check
464      - changed sponge layer relaxation parameter units for days to seconds
465      - turned off sponge layer by default
466      - changed argument list of OBCS_CALC to myTime+deltaTclock
467      - fixed about 35 bugs in obcs_external_fields_load
468    
469    checkpoint55c_post
470    o obcs stuff
471      - new runtime flags useOBCSprescribe, useOBCSbalance
472      - re-arranged obcs_calc
473      - moved exf_getobcs to obcs_prescibe_read
474        obcs_prescibe_read is called after ORLANSKI stuff
475        and independent of it (executable can contain all).
476      - updated obcs_check
477      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
478        These may be necessary only if tangential velocities are
479        prescribed at OB, not sure, needs testing.
480    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
481      which simplifies the calls and passes the ifc check-bounds test
482    
483    checkpoint55b_post
484    o add a 2D scalar, Z location, exchange_2 routine.
485    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
486      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
487      affects advect_cs results (for the wrong reason): update output.txt
488    o use a more standard discretization for biharmonic viscosity ;
489     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
490      affects results of dome set-up: update output.txt
491    o fix gad_advection.F (CubedSphere part), back to version 1.23
492    o fix bug in mom_vi_del2uv.F (CubedSphere part).
493    
494    checkpoint55a_post
495    o merged code to
496      * prescribe/read time-dependent open boundaries
497        (works in conjunction with exf, cal)
498      * sponge layer code for open boundaries
499      * each boundary N/S/E/W now has its own CPP option
500        (healthy for the adjoint)
501    
502    checkpoint55
503    o up-to-date adjoint of previous breaks
504      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
505      - global_ocean_ebm: adjoint still needs fix (TLM ok)
506      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
507      - carbon: * remove tr1-related adjoint verification
508                * add ptracer as control variable
509    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
510      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
511    
512    checkpoint54f_post
513    o in verification/carbin/ remove experiment related to
514      ALLOW_PASSIVE_TRACER (array tr1 etc)
515      code_ad/ input_ad/ results_ad
516    
517    o add two new packages
518      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
519        + subject to optimization (memory)
520      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
521        + subject to reordering (many GOTOs in the original code)
522        + so far opps is called for every (i,j) point, and then operates in
523          the vertical; one may want to reorder the scheme in order operate in
524          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
525          fields)
526    o overhaul of IO so that we now have flags for MDSIO and/or MNC
527      - all verification tests compile and run with linux_ia32_g77
528      - defaults are compatible with current input files--nothing
529        should change if you were not previously using MNC
530      - MNC output has been added in numerous places (eg. timeave)
531        but there are still a few writes not yet do-able with MNC
532        (this is in progress)
533      - flags now allow for either/or/both use of MDSIO and MNC and
534        documentation will soon follow
535      - numerous small formatting cleanups for ProTeX
536    o add version info (via BUILD_INFO.h) to MNC and stdout
537    
538    checkpoint54e_post
539    o add two new packages
540      - pp81 (Packanowski and Philander, 1981), Richardson number and
541        stratification dependent mixing
542      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
543      - these scheme operate in a similar manner as KPP (without ghat, of
544        course), however there is only one diffusivity that is used for both
545        temperature and salinity (and passive tracers)ç
546    o add offline package
547    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
548      provided by Stephanie Dutkiewicz
549    o genmake2: add ability to search for C compilers and cleanup test output
550      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
551    
552    checkpoint54d_post
553    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
554    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
555      leading to additional shift by 5 days each year of integration
556       (i.e. leading to considerable offset over the years)
557    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
558    o start with no AB and no initial filtering (staggerTimeStep):
559      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
560    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
561      (external loading & cpl import/export stay in forward_step.F)
562    o update coupling interface to work with new staggerTimeStep
563    o change MDSIO ptracers_pickup.
564    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
565    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
566    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
567    
568    checkpoint54c_post
569    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
570      this affects (truncation error) output.txt of test-exp:
571       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
572    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
573    o change Qnet to always be the net heat flux, (+upward).
574      affects (truncation error) output of natl_box exp.: updated
575    o define the max number of passive tracers in PTRACERS_SIZE.h
576    o start to test mnc routinely in exp0
577    o add sea-ice loading (sIceLoad) as a new forcing field.
578    
579    checkpoint54b_post
580    o add testreport "-j JOBS" option for parallel builds (tested and pretty
581       impressive on Altix and Opteron systems)
582    o diagnostics can now write NetCDF files through the mnc package
583    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
584    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
585    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
586      affects (truncation error) output of lab_sea & natl_box exp.: updated
587    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
588    
589    checkpoint54a_post
590    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
591    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
592    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
593    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
594      + internal_wave (shift in writing cg2d_ini_res)
595    checkpoint54a_pre
596    
597    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
598      - modified verification/lab_sea and natl_box_adjoint accordingly
599    
600    checkpoint54
601    checkpoint53g_post
602    o prepare splitting of thermodynamics: store convect.counter in common block
603    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
604      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
605    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
606    o new parameter "nShapS": allow to treat differently S from T (nShapT)
607    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
608    o restore adjointability
609    
610    checkpoint53f_post
611    o modifications that affect AIM experiment results (update output.txt):
612      - no advection of S at top interface Nr (pkg/generic_advdiff)
613      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
614    o AIM pkg:
615      - include stability function into surf.Flux derivative relative to Tsurf
616      - calculate clear-sky radiation & surface temp. change (for diagnostics)
617    
618    checkpoint53e_post
619    o merged cylindrical coord configuration
620    o added rotating_tank experiment
621    checkpoint53e_pre
622    
623    checkpoint53d_post
624    o faulks upgraded: re-generate output.txt that have changed:
625       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
626    o Added Bryan and Lewis, 1979, vertical diffusivity profile
627    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
628    o added Sadourny discretization of Coriolis
629      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
630      - re-enabled use of omega3 (useAbsVorticity)
631    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
632      vector-invariant equations
633      - note: does *NOT* yet use same variable visc. for no-slip BC's.
634    o recoded the lateral boundary conditions for non-hydrostatic w, this time
635      hopefully without new bugs
636      - still to do: biharmonic friction for non-hydrostatic w
637    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
638    o regenerated output for global_ocean_ebm (using -ieee)
639    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
640      of mom_common/
641      - simple re-arrangement of instructions within computing loop
642    checkpoint53d_pre
643    
644    checkpoint53c_post
645    o new version of coupler for AIM+thSIce and Ocean models
646     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
647     - land: change Evaporation of snow
648     - aim with thSIce: fix bug in snow-precip.
649    o changes to calc_gw.F
650     - bug fix for w^2 term near the bottom boundary
651     - (hopefully) improve the lateral slip boundary condtions for use with
652        partial/looped cells
653      - because the bug fix changes two verification experiments anyway (exp5
654        and plume on slope), change the lateral boundary condition from half slip
655        to the value of no_slip_sides
656    o ebm package wasnt quite up to the parallel task. Fixed that.
657    o Adjoint of EBM package + verification
658      * TLM OK
659      * ADM not sufficient accuracy yet (needs further testing)
660    
661    checkpoint53b_post
662    o Commiting new energy balance model to repository
663      * package is pkg/ebm
664      * verif. is verification/global_ocean_ebm
665      * references are in ebm_driver.F
666    C      * X. Wang, P. Stone and J. Marotzke, 1999:
667    C        Global thermohaline circulation. Part I:
668    C        Sensitivity to atmospheric moisture transport.
669    C        J. Climate 12(1), 71-82
670    C      * X. Wang, P. Stone and J. Marotzke, 1999:
671    C        Global thermohaline circulation. Part II:
672    C        Sensitivity with interactive transport.
673    C        J. Climate 12(1), 83-91
674    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
675    C        Destabilization of the thermohaline circulation
676    C        by atmospheric eddy transports.
677    C        J. Climate 7(12), 1870-1882
678    o Will need long integration testing.
679    checkpoint53b_pre
680    
681    o created pkg/mom_common in preparation for variable viscosity code
682    o renamed and split ini_mnc_io
683    o pkg/land: only liquid water can diffuse or run-off
684    o AIM using land: soil wetness availability account for snow
685    o added printMapIncludesZeros to EEPARMS namelist
686    
687    checkpoint53a_post
688    o restore TAMC compatiility for exf_constants.h
689      (no usage of _d in .h)
690    o Additional storing in KPP in an attempt to fix
691      TAMC problem with adjoint of KPP code.
692      (no success...)
693      Identical code works fine with TAF.
694    o Fixed verification/natl_box_adjoint experiments.
695      Initial conditions for Experiments 4 and 5 are now
696      set to "SEAICE_initialHEFF=0", which is more reasonable,
697      and hence gives results closer to that of Experiment 2.
698      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
699    
700    checkpoint53
701    o stable checkpoint with up to date adjoint
702      TLM tests only run for 1st grdchk at the moment. Its unclear if
703      this is a code problem or a problem with resetting code for g_
704      variables that is being autogenerated wrong.
705      Otherwise:
706       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
707       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
708         are both still in chaos following their security messes.
709    
710    checkpoint52n_post
711    o various build (mostly genmake2) changes including:
712      - ability to build/run more easily within Cygwin and MacOS X
713      - more complicated Makefiles with a stronger dependence on Gnu Make
714    o pkg/seaice modifications
715      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
716        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
717        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
718      - changed proxy for geostrophic velocity and updated
719        verification/lab_sea/results/* accordingly
720      - removed ADI dynamic solver from pkg/seaice
721      - replaced all occurrences of 1/CSTICE or 1/CSUICE
722        they caused a segmentation fault under certain circumstances
723      - removed unused field WATR
724    o bug fix in exf-package:
725      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
726         now reflect that.
727    o small fixes in the cal-package:
728      - set reference date to first of January for the 'model'-calendar
729      - failing of cal_CheckDate in cal_FullDate now actually results in a
730        warning
731    o small modifications in exf-package to increase flexibility:
732      - change climtempfreeze from a constant to a runtime parameter that
733        is specified in data.exf_clim (default = -1.9)
734      - introduce runtime parameter windstressmax (default = 2.0) that is
735        specified in data.exf
736    o fix in pkg/thsice:
737      - update Evap (Tsf changes) to be consistent with Latent heat flux
738      - maintain snow precipitation unchanged (even if Tsf >=0).
739     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
740    
741    checkpoint52m_post
742    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
743      this does not change any of the results, because myIter=0 in swfrac always
744      lead to jwtype=2 (the default anyway), but the call makes little sense
745      as a default
746    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
747    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
748      atmospheric model (AIM) to use it ; add a "slab ocean" component.
749    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
750    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
751    o extending useSingleCpuIO option to work with new exch2 I/O format
752      - old-style, missing-tile I/O is still accessible by defining CPP
753        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
754    o monitor package can write to NetCDF files and/or STDOUT
755    o fix re-definition bug in MNC_GRID_INIT_ALL()
756    o doc/api_reference added
757      - a framework for building an API Reference Manual using all
758        the "protex" comments embedded in the code
759      - see pkg/generic_advdiff, pkg/mnc for examples
760    o MNC:

800    o fixed bug introduced in pkg/monitor
801    o accuracy ctrlprec = 32 insuffient for gradient checks using
802      averaged fields (I/O via cost_averages)
803      -> use ctrl.h in active_file*.F to control I/O precision.
804    o paramter list of CALL ADTHE_MAIN_LOOP
805    o added initial do_the_model_io to ecco
806    o set all ...Freq to zero after cost_final

811    o fix nchklev in tamc.h for global_ocean...
812    o Bringing flow and store directives up-to-date
813    o Really weird thing!
814      call do_the_model_io from the_main_loop with parameters
815      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
816      TAF places a faulty re-call of initialise_varia
817      after cost_final call which should not be there!
818    checkpoint52j_pre
819

850    o added temporary hack for sea-ice dynamics on the cube:
851      metric terms are ignored and it is assumed that
852      there is no sea-ice on cube faces 1, 2, 4, and 5.
853    
854    checkpoint52f_post
855    o added exch2 cube routines to pkg/exch2

860    checkpoint52e_post
861    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
862      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
863    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
864      to work with implicit vertical advection and AB ;
865    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
866    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
867     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
868    checkpoint52e_pre
869    
870    o fix bug in impldiff when Nr=1 or Nr=2.
871    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
872    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
873    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
874      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure

880    o re-tiled many expts to allow comparison in multi-processor mode
881      - updated output accordingly
882      - changed hs94.128x64x5 to use intial T from file rather than use the
883        random number generator
884    o add infrastructure in model routines for fizhi and gridalt packages
885    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
886    o changes to permit hi-res, cubed-sphere, configuration
887      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
888      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
889      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
890        of surface winds for the cube
891      (A verification experiment, based on global_ocean.cs32x15, but with
892       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
893       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
894       complete with example surface forcing files and matlab scripts to look
895       at the output and compare it with that of global_ocean.cs32x15.)
896    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
897       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
898       to conform to the common rule.
899    o check-in the first version of the coupler + interfaces for multi-components
900       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
901       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
902       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
903       - ocean and atmos. share the same horizontal grid (no interpolation).
904       - exchanges between component and coupler is done in forward_step
905    o new verification experiment, cpl_aim+ocn:
906       coupled ocean - AIM atmosphere on cs32 grid.
907    
908    checkpoint52d_pre
909    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
910    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
911    
912    checkpoint52c_post
913    o Fixing OPTIONS files for use of exf:
914      - ALLOW_ECCO not needed
915      - ECCO_CPPOPTIONS.h should not be included from
916        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
917        as has been the case in the past
918      - All cal/exf related options are currently set in
919        single header file. Should remain so until we
920        agree on a consistent new policy.
921    o Removed all CPP options for cal package.
922      cal has no more CPP options.
923    o modified STOREs in GAD_ADVECTION
924    o corrected key comp. for passkey
925    
926    checkpoint52b_post

928     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
929     - modify fluxes but do not change theta directly;
930     - light cleaning of bulk_force pkg (still needed with thsice).
931     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
932       + output_thsice.txt to test thsice & bulk_force pkgs.
933    o put back grid & coriolis monitor output.
934    checkpoint52b_pre
935    
936    o call "do_the_model_io" at the beginning (=> dump initial state)
937    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
938    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
939      (need info on NUMBER_OF_PTRACERS)
940    o missing PTRACERS headers in some routines
941    o default tamc.h in pkg/autodiff supposed to crash
942      to ensure proper customization
943    
944    checkpoint52a_post
945    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
946      - moved surfaceTendencyTice from pkg/seaice to main code
947      - subroutine FREEZE_SURFACE now limits only surface temperature
948        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
949        => new output.txt for global_ocean.cs32x15 & global_with_exf
950      - keep the old version of FREEZE for backward compatibility;
951        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

960    o some bug fixes for #undef REAL4_IS_SLOW
961    
962    checkpoint52 = ecco_c52_e35
963    o after testing adjoints of checkpoint51u_post
964    
965    checkpoint51u_post
966    o this is the post-merge tag of the ecco-branch
967      (needs another clean checkout and re-testing)
968    o various natl_box_adjoint configs and results
969      but no input fields
970    o obcs adjoint not yet merged!
971    o adding ECCO global 1x1 and 2x2 degree configs
972    o updated/extended some store directives for seaice
973    o pkg/ecco now containes ecco-specific part of cost function
974    o top level routines the_main_loop, forward_step

978    o in ctrl/ cleaned some cross-dependencies and updated CPP options
979    
980    checkpoint51t_post
981    o this is the pre-merge tag of the ecco-branch
982    
983    checkpoint51s_post

985    o pkg/grdchk
986      - renamed 'ph-grd 3' to 'grad-res'
987      - merged from ecco-branch
988        (remaining bug fixes for obcs gradient checks)
989      - additional high-precision output for testreport
990        (grep for 'precision_grdchk_result')
991    
992    checkpoint51r_post
993    o cleaned up or removed CPP_OPTIONS.h files
994    o updated results for some of the tests to reflect the new
995      optfiles (-ieee: -O0 instead of -O3)
996    
997    checkpoint51q_post
998    o cd_code:
999      - moved cd_scheme.F -> cd_code_scheme.F
1000      - separate read_checkpoint from cd_code_ini_vars.F

1008      - ctrl_pack/unpack cleaned
1009        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1010      - confined inclusion of AD_CONFIG.h to where necessary.
1011    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1012    
1013    checkpoint51p_post
1014    o create initial cd_code package
1015      - WARNING: the initialization of fields within packages
1016        is broken because INI_FIELDS (where READ_CHECKPOINT is
1017        called) is called *before* PACKAGES_INIT_VARIABLES.
1018        This seems to be backwards since
1019        1) its important to initially zero the entire field including
1020           the "halo" region
1021        2) zeroing needs to be done *before* reading pickup info
1022           and the pickup call might or might not happen in any
1023           particular run
1024      - this needs an overhaul for R2
1025    o cleanup verification/*/code/GMREDI_OPTIONS.h
1026    o cleanup testreport
1027    
1028    checkpoint51o_post

1036    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1037    o bug fix in find_alpha.F for MDJWF:
1038      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1039        change rho -> rho-rhoConst
1040      - replace call find_rho to find_rhonum

1060      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1061      - subroutine FREEZE now limits only surface temperature
1062        (this means new output.txt for global_ocean.90x40x15,
1063         global_ocean.cs32x15, and global_with_exf)
1064    o added surface flux output variables to TIMEAVE_STATVARS

1092    
1093    checkpoint51k_post
1094    o change default to: useNHMTerms=.FALSE.

1172    o AIM : add stratospheric drag in the upper level
1173    
1174    checkpoint51d_post
1175    o change function ILNBLNK (=> last non-blank char.) to return zero

1177    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
1178    o modif's to restore TAMC compatibility
1179      - avoid "_d" constructs in PARAMETER declarations
1180      - avoid interrupting lines by comment lines
1181    o Use cluster local disks for purely local I/O
1182      vs. globally visible disks needed for ctrl stuff
1183      (merged from ecco-branch)
1184      - new active_file_loc... and mdsio_..._loc routines
1185      - affected packages: autodiff, ctrl, grdchk, mdsio
1186    
1187    checkpoint51c_post
1188    o introducing integer flag debugLevel
1189      - debLevZero: suppress all output
1190      - debLevA: standard
1191      - debLevB: equivalent to current debugMode=.TRUE.
1192    o introducing pathname variable mdsioLocalDir for mdsio
1193      that can be specified at runtime
1194      (relevant for cluster I/O to local disk)
1195    `
1196    >>>checkpoint51b_post
1197    adjoint of ptracers
1198    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1199    o extended state in checkpoint_lev?, etc.
1200    o alternative ctrl/cost with tr1 or ptracer
1201    o new comlev1_bibj_ptracers
1202    o new ptracers.flow
1203    o made ptracers_forcing same as external_forcing_s
1204    o added verification for adjoint with ptracers
1205      - adm. grdchk fail so far
1206      - tlm. grdchk OK
1207      - checked tapelev/comlev recomputations: OK
1208    <<<checkpoint51b_pre
1209    
1210    checkpoint51a_post
1211    o added code for biogeochemistry package
1212      - new pkgs: dic, gchem
1213      - new subroutine in ptracers
1214    o modify code for biogeo packages
1215      - in model/src and pkg/ptracers
1216    
1217    checkpoint51
1218    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1219      - autodiff, ctrl, exf, grdchk, seaice
1220      kept separate packages
1221      - cost, ecco, obcs
1222    o updating verification/internal_wave, verification/lab_sea
1223      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1224    
1225    checkpoint50i_post
1226    o Preparing next differentiable checkpoint and sync
1227      of MAIN vs. ecco-branch
1228      - 1st step: this one is differentiable
1229      - 2nd step: next(! not this) checkpoint will have updated packages
1230                  from ecco-branch)
1231    
1232    checkpoint50h_post
1233    o new package "land": provide surface BC for AIM.
1234    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1235    o AIM: use true log-P extrapolation for near surface temp (= as in
1236        F.Molteni paper) ; update aim.5l_cs output.
1237    o New variable in PARM03 for more flexible pickups
1238    o somewhat cleaned package initialisation sequence for
1239      ctrl/ cost/ ecco/ in packages_... routines
1240    
1241    checkpoint50g_post
1242    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1243      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1244      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1245        made the default because of faster convergence than ADI
1246    
1247    checkpoint50f_post
1248    o exf totally restructured
1249      - replaced all exf_set_ routines by one generic exf_set_gen.F
1250        and made sure it's still differentiable
1251      - split exf_getffields.F into new exf_bulkformulae.F
1252      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1253      - updated adjoint/makefile and relevant verif. accordingly
1254    
1255    checkpoint50f_pre

1263     o removed lots of single quotes from comments
1264    
1265    checkpoint50e_post
1266    o make KPP work with PTRACERS
1267     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1268       nearly a copy of kpp_transport_s
1269     - there is no analogue to SurfaceTendencyS, so I have to use
1270       gPtr(of the surface layer) instead
1271    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1272    checkpoint50e_pre
1273    
1274    checkpoint50d_post
1275    o change kpp output from multiple-record state files to single-record state
1276      files analogous to write_state.F
1277    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1278      analogous to the cg2d-related output.
1279    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1280      so that writing to internal file fn (with length 512) fails.
1281    checkpoint50d_pre
1282    
1283    checkpoint50c_post
1284    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1285    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1286    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1287    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1288    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1289    
1290    checkpoint50c_pre
1291    Merging from release1_p13:
1292    o bug fix for pkg/seaice dynamic solver
1293    o Added SEAICE_initialHEFF to pkg/seaice
1294    
1295    checkpoint50b_post
1296    o store u*,v* in gU,V instead of in guNm1,gvNm1
1297    o in order to put the momForcing out of the Adams-Bashforth:
1298      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1299      to timestep.F
1300    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1301    o re-generate output for highly sensitive test-exp:
1302       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1303    
1304    checkpoint50b_pre
1305    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1306    o corrected CPP option mismatch in exf_Bulk... functions for case
1307      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1308    
1309    checkpoint50a_post
1310    o Bug fix for merging between c50 and KPP.
1311      ikey was passed from thermodynamics to kpp_calc via
1312      common block rather than being recomputed in kpp_calc,
1313      in contradiction with new key itdkey.
1314      New key ikppkey created, and tamc.h headers updated.
1315    
1316    checkpoint50
1317    - 2nd step of merge with ecco-branch:
1318      merge changes in ecco-branch back into main trunk
1319    - bug fix in find_alpha
1320    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1321    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1322    - merged some sliced AD support routines
1323    
1324    checkpoint49
1325    merged from ecco-branch:
1326    o exf:
1327      - Enable initialisation of forcing fields to constant
1328        (runtime) values.
1329      - in exf_getffields.F
1330        Reduce i-/j-loop to interior domain, discarding overlaps.
1331        That also fixes wrong TAF-key computations for key_1, key_2
1332        with bulf formulae.
1333      - exf_init.F modify #ifdef for exf_init_evap
1334      - exf_getffieldrec.F, ctrl_getrec.F
1335        The following INT-usages are not safe:
1336          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1337          fldcount = int(fldsecs/fldperiod) + 1
1338        and were modified.
1339    o autodiff: checkpoint_lev...
1340      - updated storing for bulk formulae (some arrays were missing)
1341      - added state for seaice package
1342      - synchronized with main branch
1343    o DIVA:
1344      Modif.s in
1345      - the_main_loop.F
1346      - the_model_main.F
1347      and added cost_final_restore.F cost_final_store.F
1348      o With these changes, it is possible to fully separate
1349        the first forward run to compute the cost function (mdthe_main_loop)
1350        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1351        into separate model executions.
1352        This enables better tuning of DIVA to given queue sizes.
1353      o Loss of cost function value in consecutive DIVA runs is
1354        fixed by storing to 'costfinal' file.
1355      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1356        beginning/end of adjoint integration is accounted for.
1357      The current changes apply to TAF-1.4.26.
1358      TAF has one remaining bug, requiring one manual change
1359      (see MITgcm manual).
1360    o cal: synchronized between MAIN and ecco-branch
1361    
1362    checkpoint48i_post
1363    o Changes to restore differentiability of code w.r.t. previous tag
1364      (mostly adding new routines to make list and replacing
1365      pressure by totPhiHyd).
1366    o Updated and merged grdchk package
1367      - has both ADM and TLM checks
1368      - works for single- and multi-proc.
1369      - output cleaned
1370      - worked successfully for parallel DIVA
1371    o genmake:
1372      - Adding -platform=SP4
1373      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1374    o Modif. for DIVA:
1375      ctrl_unpack should not be called in intermediate DIVA interval.
1376      (similar thing would apply for active files such as
1377      tbar, sbar, psbar, which should not be reinitialised;
1378      only relevant for ecco-branch)
1379    
1380    checkpoint48h_post
1381    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1382    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1383    o Added SEAICE_initialHEFF to pkg/seaice
1384    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1385    
1386    checkpoint48g_post
1387    --- EOS:
1388    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1389      store total Potential in totPhyHyd for diagnostics & EOS.
1390    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1391    --- Pressure/geopotential gradient:
1392    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1393    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1394      ( changes results of global_ocean_pressure )
1395    o NLFS + z-coord.: add eta*Rho' contribution.
1396    o accurate phiHyd when using interface-W at the middle between 2 centers
1397     ( changes results of ideal_2D_oce )
1398    o includes r* 2nd term in potential gradient.
1399    
1400    checkpoint48f_post
1401    Merging from release1_p12:
1402    o Modifications for using pkg/exf with pkg/seaice
1403      - improved description of the various forcing configurations
1404      - added basic radiation bulk formulae to pkg/exf
1405      - units/sign fix for evap computation in exf_getffields.F
1406      - updated verification/global_with_exf/results/output.txt
1407    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1408      (SBO) core products, including oceanic mass, center-of-mass,
1409      angular, and bottom pressure (see pkg/sbo/README.sbo).
1410    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1411      to avoid negative values in shallow regions.
1412      - updated verification/natl_box/results/output.txt
1413      - updated verification/lab_sea/results/output.txt
1414    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1415    o Added useSingleCpuIO option (see PARAMS.h).
1416    o Updated useSingleCpuIO option in mdsio_writefield.F to
1417      work with multi-field files, e.g., for single-file pickup.
1418    o pkg/seaice:
1419      - bug fix in growth.F: QNET for no shortwave case
1420      - added HeffFile for specifying initial sea-ice thickness
1421      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1422    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1423      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1424    o pkg/seaice:
1425      - adjoint-friendly modifications
1426      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1427    
1428    checkpoint48e_post
1429    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1430    o dynamics: change definition of computational domain & adapt mom_fluxform
1431      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1432    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1433        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1434        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1435        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1436        inverted_barometer solid-body.cs-32x32x1
1437      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1438    
1439    checkpoint48d_post
1440    o in preparation for r*:
1441     a) use pre-computed gradient of hydrostatic potential:
1442        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1443     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1444        => affects results of glob_oce_pressure (different truncation error)  
1445      update output.txt of ideal_2D_oce & global_ocean_pressure
1446    
1447    checkpoint48d_pre
1448    o in preparation for r*:
1449      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1450      pass the 2 comp. of the grad. as arguments to momentum S/R.
1451      but for the moment, only used if it does not change the results.
1452    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1453    
1454    checkpoint48c_post
1455    Modifications in treatment of initial flux forcing controls
1456    to avoid extra storing of flux fields.
1457    
1458    checkpoint48c_pre
1459    o Added tidal_basin_2d experiment (currently 1D!)
1460    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1461    
1462    checkpoint48b_post
1463    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1464     (modification to pressure gradient not yet implemented)
1465    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1466      (for U & V) that are used for vertical advection of momentum.
1467    
1468    checkpoint48a_post
1469    o In preparation for r*, use temp. array to compute vertical transport
1470       in flux-form momentum pkg. => change results of few test-exp.
1471      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1472                        lab_sea, natl_box & plume_on_slope
1473    
1474    checkpoint48
1475    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1476    
1477    checkpoint47j_post
1478    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1479    o moved adexch from forward_step to addummy_in_stepping
1480    o added exch in ctrl_map_...
1481    o aveFreq.=0. at end of cost_final to avoid overwrite in
1482      reverse checkpointing loop
1483    o Yet more changes in gmredi:
1484      * adgmredi_calc_tensor
1485        avoiding all recomputation of gmredi_slope_limit
1486      * adgmredi_x/y/rtransport
1487        added flag for excessive storing to avoid recomp. of
1488        u/v/rtans, dTdx/y/z
1489        -> this is not really necessary and very memory-consuming
1490      * adgmredi_slope_psi:
1491        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1492      * gmredi_slope_limit
1493        re-activated full calculation of taperfct for case 'ac02'
1494    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1495    
1496    checkpoint47i_post
1497    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1498    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1499      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1500    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1501    o gmredi: fix few bugs.
1502    
1503    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1504    This will be a good checkpoint to plug into the ecco-branch.
1505    o few modif.'s to get latest version adjointed
1506      (mainly kick out code in ini_linear_phisurf)
1507    o modif's to run adjoint with exactConserv
1508    o case GM_BOLUS_ADVEC should be cleaned
1509      S/R gmredi_slope_psi should be cleaned
1510    o verification/carbon now has exactConserv=.TRUE.
1511    
1512    checkpoint47g_post
1513    o time-average AIM output: becomes independent from statvars time-average
1514      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1515    o After TAF bug fix:
1516      Tested adjoint of gmredi package.
1517      Tests were done with checkpoint47 rather than with latest
1518      checkpoint47f_post since the latter is broken for the adjoint
1519      verification/carbon/ contains both ADM and TLM gradient checks.
1520    Here they are, before they get changed/lost/stolen.
1521    Mostly modif.'s to fix numerical sensitivities.
1522    Gradient checks OK for
1523    - GM_taper_scheme:
1524      * clipping
1525      * ac02
1526      * linear
1527      * glw91
1528      * dm95
1529      * ldd97
1530    - GMREDI_OPTIONS:
1531      * GM_VISBECK_VARIABLE_K
1532      * GM_NON_UNITY_DIAGONAL
1533      * GM_EXTRA_DIAGONAL
1534      * GM_BOLUS_ADVEC
1535    in conjunction with data.gmredi parameters to be checked in
1536    in a few minutes under verification/carbon/code/
1537    
1538    checkpoint47f_post
1539    Merging from release1_p10:
1540    o modifications for using pkg/exf with pkg/seaice
1541      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1542        and SEAICE_EXTERNAL_FLUXES
1543      - pkg/exf CPP options EXF_READ_EVAP and
1544        EXF_NO_BULK_COMPUTATIONS
1545      - usage examples are Experiments 8 and 9 in
1546        verification/lab_sea/README
1547      - verification/lab_sea default experiment now uses
1548        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1549    
1550    checkpoint47e_post
1551    o created a tag prior to creating a branch
1552    
1553    checkpoint47d_post
1554    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1555      at the bottom boundary had an erroneous half slip boundary condition
1556    o added bottom drag and no slip boundary condition capabilities to
1557      oceanic pressure coordinates code
1558    o added new verification experiment global_ocean_pressure, this experiment is
1559      also described in the tutorial section of the manual
1560    checkpoint47d_pre
1561    
1562    checkpoint47c_post
1563    o Added a verification experiment for a global cubed-sphere ocean run
1564      -  verification/global_ocean.cubed32x32x30
1565      -  uses pkg/therm_seaice and pkg/bulk_forcing
1566    
1567    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1568    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1569      when using P-coordinate; only implemented for atmospheric config.
1570    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1571      NOTES: requires option NONLIN_FRSURF to be "#define".
1572    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1573    
1574    checkpoint47b_post
1575    Merging from release1_p9:
1576    o pkg/seaice
1577      - removed GOTO's and added taf directives
1578      - double precision constants to reduce the g77 (Linux)
1579        to F77 (SGI) differences reported in release1_p8
1580    o tools/genmake
1581      - added SGI options
1582    o verification/testscript
1583      - updated to that of checkpoint47a_post
1584    o verification/global_ocean.90x40x15/input/eedata
1585      - modified for SGI f77 compatibility
1586    o verification/lab_sea
1587      - added description of sea-ice model
1588      - added missing matlab routines
1589      - added test of thermodynamics parallelization
1590    
1591    checkpoint47a_post
1592    o new pkg: aim_v23
1593     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1594       for now, keep the same surface forcing as before.
1595     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1596     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1597     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1598    o add diagnostic of surface correction term in monitor output
1599    
1600    o bulk_force and therm_seaice
1601    - Two packages:  bulk_force (Bulk forcing)
1602      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1603    - Earlier integration from Stephaine Dutkiewicz
1604      and Patrick Heimbach.
1605    - Two ifdef statements for compile time,
1606       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1607    
1608    checkpoint47
1609    differentiable version of checkpoint46n_post
1610    o bug fix in quasihydrostaticterms
1611    o * "clean" adjoint code (in terms of extensive recomputations)
1612        can now be obtained for all GMREDI options (i.e. for
1613        - GM_VISBECK_VARIABLE_K
1614        - GM_NON_UNITY_DIAGONAL
1615        - GM_EXTRA_DIAGONAL
1616        - GM_BOLUS_ADVEC )
1617      * However, wrong gradient check problem remains unsolved.
1618      * New CPP options have been introduced for different
1619        tapering schemes
1620    o external_fields_load now part of differentiation list
1621    o pressure needs multiple storing;
1622      would be nice to have store_pressure at beginning or
1623      end of forward_step, e.g. by having phiHyd global (5-dim.)
1624      (NB: pressure is needed for certain cases in find_rho,
1625      which is also invoked through convective_adjustment).
1626    o recomputations in find_rho for cases
1627     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1628    o #define ATMOSPHERIC_LOADING should be differentiable
1629    o ini_forcing shifted to begining of initialise_varia
1630    o Incorporating QNVS line search routines into MITgcm
1631      (this is separate code, and therefore not under pkg)
1632      lsopt/, optim/
1633    o Updated verification/carbon/
1634      - #define GM_VISBECK_VARIABLE_K
1635      - GM_taper_scheme    = 'ldd97'    
1636    
1637    checkpoint46n_post
1638    Merging from release1_p8:
1639    o verification/natl_box:
1640      updating new external_fields_load routine
1641    o New package: pkg/seaice
1642      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1643      The sea-ice code is based on Hibler (1979-1980).
1644      Two sea-ice dynamic solvers, ADI and LSR, are included.
1645      In addition to computing prognostic sea-ice variables and diagnosing
1646      the forcing/external data fields that drive the ocean model,
1647      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1648      The implied surface heat flux is then stored in variable
1649      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1650      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1651      non-local transport term.  Because this call precedes model
1652      thermodynamics, temperature under sea-ice may not be "exactly" at
1653      the freezing point by the time theta is dumped or time-averaged.
1654      N.B.: fairly large differences in accuracy occur across
1655            different platforms/compilers; comparison between
1656            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1657            generated output gives:
1658       T           S           U           V
1659      C D M    c        m  s        m  s        m  s        m  s
1660      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
1661      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d

1663    
1664      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1665    o GAD:
1666      - generated new common blocks to account for call of
1667        same gad routines with differing traceridentities
1668        (needed to modify tracerIdentity indices in GAD.h)
1669      - generated separate common blocks for case useCubedSphereExchange
1670        (Department of Futurology)
1671      - parameter lists to gmredi_?transport: added tracerIdentity
1672      - added new key indices to tamc.h
1673    o external_fields_load:
1674      - added this routine to TAF list
1675      - needed to make some common blocks global and additional storing
1676        along the same lines as exf package (checkpoint_lev?_directives.h)
1677    o exf:
1678      updated external forcing package
1679      - bug fixes carried over from ecco-branch
1680        (missing OBCS_OPTIONS.h in two routines)
1681      - enable easy to use "no forcing".
1682      - added exf I/O for atmospheric loading
1683      - added exf I/O for runoff data
1684      - transfered scaling between exf <-> MITgcm to exf namelist
1685    o Adding new verification experiment global_with_exf.
1686      This verification experiment is almost identical to the
1687      global_ocean.90x40x15 experiment, except that it uses
1688      the exf (and cal) package instead of the
1689      external_fields_load routine (cf README file).
1690    
1691    checkpoint46m_post
1692    o modified testscript to return -- when there are no lines of "%MON" output
1693    o added new flag "quasiHydrostatic" for QH mode
1694      and new routine quasihydrostaticterms()
1695    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1696      New routine: mom_u_coriolis_nh()
1697    o fixed sign of non-hydrostatic metric terms in u and v equations.
1698      Depend on correct sign of gravitySign.
1699    o added work.pc* to .cvsignore in aim directories using ifc
1700    o introduced flag for controllin non-hydrostatic metric terms
1701    o removed gravitySign from PARM04
1702    o switched to g77/ifc from pgf77 in aim experiments
1703    
1704    checkpoint46l_post
1705    o made convective adjustment work with pressure coordinates:
1706     - changed the direction of k-loop in convective_adjustment.F for the
1707       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1708     - adjusted the reference pressure k-index in convective_adjustment.F
1709     - adjusted the convection condition in convect.F (in analogy to
1710       calc_ivdc.F)
1711     - convective_adjustment no longer computes anything on the halos
1712     - removed the warnings about negative salinity from find_rho.F and
1713       find_alpha.F; instead the new routine look_for_neg_salinity, called
1714       at the beginning of find_rho, find_alpha, and find_beta, does a
1715       check of the entire slice, if CPP-option
1716       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1717    checkpoint46l_pre
1718    
1719    checkpoint46k_post
1720    o fixed the verification/global_ocean.90x40x15 experiment:
1721     - new bathymetry (the world according to A., JMC, and M.)
1722     - new initial fields and forcing fields (*.bin files)
1723     - new POLY3.COEFFS (for the next release one should switch to a full
1724       equation of state: JMD95P or MDJWF)
1725     - fixed several errors and redundancies in the data file
1726     - experiment uses looped cells
1727     - added matlab directory with diagnostic scripts for plotting of output
1728    
1729    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1730     - read AIM physics parameters from a file (data.aimphys)
1731     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1732    
1733    checkpoint46j_post
1734    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1735    o move wVel computation at the end of the time step, in S/R integr_continuity
1736    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1737    o update timeave pkg for wVel diagnostic.
1738    checkpoint46j_pre
1739    
1740    checkpoint46i_post
1741    o Clean up AIM package (and keep the results unchanged):
1742      include CPP_OPTION and use IMPLICT NONE in all routines ;
1743      declare all the variables _RL ; use _d 0 for all numerical constants.
1744      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1745    
1746    checkpoint46h_post
1747    o cleaned up the use of rhoNil and rhoConst.
1748      - rhoNil should only appear in the LINEAR equation of state, everywhere
1749        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1750        and the dynamical equations are all divided by rhoConst
1751    o introduced new parameter rhoConstFresh, a reference density of fresh
1752      water, to remove the fresh water flux's dependence on rhoNil. The default
1753      value is 999.8 kg/m^3
1754    o cleanup up external_forcing.F and external_forcing_surf.F
1755      - can now be used by both OCEANIC and OCEANICP
1756    checkpoint46h_pre
1757    
1758     Added code to convert surface volume flux (fresh water) into
1759     a mass flux when using P coordinates in the ocean (OCEANICP).
1760     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1761    
1762    checkpoint46g_post
1763    o Include a new diagnostic variable phiHydLow for the ocean model
1764      - in z-coordinates, it is the bottom pressure anomaly
1765      - in p-coordinates, it is the sea surface elevation
1766      - in both cases, these variable have global drift, reflecting the mass
1767        drift in z-coordinates and the volume drift in p-coordinates
1768      - included time averaging for phiHydLow, be aware of the drift!
1769    o depth-dependent computation of Bo_surf for pressure coordinates
1770      in the ocean (buoyancyRelation='OCEANICP')
1771      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1772        Theta, Salinity, and Pressure in the parameter list. This routine is
1773        presently contained in find_rho.F. This routine does not give the
1774        correct density for 'POLY3', which would be a z-dependent reference
1775        density.
1776    o cleaned up find_rho
1777      - removed obsolete 'eqn' from the parameter list.
1778    o added two new verification experiments: gop and goz
1779      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1780    checkpoint46g_pre
1781    
1782    checkpoint46f_post
1783    o Enable tangent linear (forward mode) gradient checks:
1784      - extended active file handling to g_... files
1785      - added TANGENT_SIMULATION to theSimulationMode
1786      - extended grdchk package accordingly
1787    o added tangent linear setup in verification/carbon/code_ftl
1788    o added adjoint setup in verification/front_relax/code_ad
1789    
1790    checkpoint46e_post
1791    o Added new equation of state -> MDJWF
1792      - EOS of McDougall et al., 2002, JAOT, submitted
1793      - caveat: the equation of state is only valid for a smaller (more
1794        realistic?) range of values than JMD95P/Z and UNESCO
1795      - added masks to the calculation of pressure in store_pressure
1796      - added more check values for density in check_eos (ini_eos.F), some of
1797        the old check values are out of the range of the MDJWF-eos, so don't
1798        expect perfect matches for those
1799    checkpoint46e_pre
1800    
1801    checkpoint46d_post
1802    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1803      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1804      case of pressure coordinates. eosType='JMD95Z' in
1805      combination with buoyancyRelation='OCEANICP' now causes an error.
1806    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1807      in find_alpha/beta.
1808    checkpoint46d_pre
1809    
1810    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1811      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1812    
1813    checkpoint46c_post
1814    o Changes necessary for ocean in p-coordinates
1815     -  Added new buoyancy relation = 'OCEANICP'
1816     -  Added new parameters = gravitySign (this used to be contained inside
1817        the factor dRdZ which I added when we first switched to R coordinates).
1818     X GM/Redi is not compatible (yet)
1819     X bottom drag and no-slip need to be debugged.
1820    checkpoint46c_pre
1821    
1822    checkpoint46b_post
1823    o Added new equation of state -> JMD95Z and JMD95P
1824      - EOS of Jackett and McDougall, 1995, JAOT
1825      - moved all EOS parameters into EOS.h
1826      - new routines ini_eos.F, store_pressure.F
1827    o Added UNESCO EOS, but not recommended because it requires
1828      in-situ temperature (see JMD95)
1829    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1830      unesco.f to be used with POLY3
1831    checkpoint46b_pre
1832    
1833    checkpoint46a_post
1834    o Added (atmospheric) pressure loading
1835      - new field in FFIELDS.h, etc...
1836      - new cpp flag ATMOSPHERIC_LOADING
1837    o Changed hFacC to _hFacC in calc_phi_hyd.F
1838    o Added SHORTWAVE_HEATING to some files for consistency
1839    checkpoint46a_pre
1840    
1841    checkpoint46
1842    further merges from release1_p5
1843    o new ctrl package
1844      - adopted from ECCO environment to enable optimization
1845      - added Eliassen Palm fluxes to controls
1846    o added Eliassen Palm flux controls to gradient check package
1847    o cost package
1848      - Compatible with new ctrl package
1849      - added Eliassen Palm cost hooks
1850      - modif's of existing cost functions
1851    o Adjoint-related bug fixes in kpp:
1852      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1853      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1854    o autodiff package
1855      - flow directives:
1856        + new for S/R do_the_model_io
1857        + enhanced for S/R checkpoint
1858        + new gmredi.flow
1859      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1860        disable adcommon.h/g_common.h by default.
1861      - fixed problem for adjoint of global_max
1862    o modified verification/carbon/
1863    o New setup for adjoint of global_ocean
1864    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1865    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1866    o incorporated hooks for sponge layer code (external_forcing.F)
1867    
1868    checkpoint45d_post
1869    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1870    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1871      (affects plume_on_slope "cg2d" output)
1872    o add new parameter deltaTfreesurf for free-surface time stepping
1873    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1874    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1875    o change phiMin in exp1 (to agree with documentation)
1876    o add new flags:
1877     - T,S forcing inside/outside Adams-Bashforth
1878     - turn off temp,salt advection and/or forcing
1879     - for each tracer, define internal flag for multiDimAdvection & A-B
1880    o monitor: change definition of KE to check conservation of Energy
1881    
1882    checkpoint45c_post
1883    o Removed f90 comments ("!")
1884    o Modified initialisations to enable exf package for MITgcm
1885      (without invoking ECCO_PACKAGE).
1886    o modifications to gradient check package (Martin Losch)
1887      - enable centered differences
1888      - modified format of standard output
1889    
1890    checkpoint45b_post
1891    o cleaned exchange calls in cg2d
1892    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1893    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1894      to configure barotropic setup (Martin Losch)
1895    o moved some initialisations within bi,bj loop in dynamics
1896      (TAF flow dependency)
1897    o in initialise_varia, moved call packages_init_variables
1898      before convective_adjustment_init
1899      (corresponding adjustment of TAF tape initialisation).
1900    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1901    
1902    checkpoint45a_post
1903    o compute Rho over the whole domain (extend iMin,jMin indices)
1904    o specific exchange for X-slice domain (case Ny=1)
1905    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1906    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1907    
1908    checkpoint44h_post = checkpoint45
1909    o Fix to restore differentiability:
1910      place at which packages_init_variables is called in
1911      initialise_varia is crucial for reverse control flow.
1912    o modifications in GMRedi to enable stable adjoint
1913      (corresponding modif's in thermodynamics, dynamics)
1914    o added missing hook for sponge layer code in external_forcing
1915    o modified test cost functions
1916    o storing in gad_advection (plus removal of write(0,*)!
1917    o missing headers TR1.h added in convective_adjustment routines
1918    o errorMessageUnit set non-equal zero in eeboot
1919      (conflict on some platforms, e.g. IBM SP3)
1920    o modified carbon verif.
1921    
1922    checkpoint44h_pre
1923    o vertical grid option: allow to put the Interface at the middle between
1924      2 cell-centers ; replace delZ in pkg/kpp by drF.
1925    o GM Advective form: Tracers are advected using the residual transport (=
1926      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1927    
1928    checkpoint44g_post
1929    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1930      results) ; ifdef missing in thermodynamics.F
1931    
1932    checkpoint44f_pre,checkpoint44f_post
1933    o added PTRACERS package
1934      This allows an arbitrary number of passive tracers to be integrated
1935      forward simultaneously with the dynamicaly model.
1936      + Implemented so far:
1937        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1938        - I/O and checkpointing
1939        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1940      + Not implemented so far:
1941        - KPP
1942        - OBCS
1943      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1944        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1945        line in data.pkg.
1946      + This package is disabled by default since it increases storage.
1947    
1948    
1949    o testscript: added -cleanup option
1950    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1951                 b) enable to filter 2D fields.

2042    checkpoint40pre8
2043    o new package rw/
2044      Added method for dumping intermediate local arrays:
2045      mdsio_writetile - same as mdsio_writefield except works from inside
2046                        bi,bj loop
2047      mdsio_writelocal - same as mdsio_writetile except works for local
2048                         arrays
2049      write_local_r? - higher-level wrapper for mdsio_writelocal
2050      Controlled by diagFreq. Defaults to zero (ie. no dumps)
2051      Example given at end of mom_vecinv.F that dumps some local arrays.

2055      or genmake -DISABLE ...
2056    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
2057      (additional storing is now needed for case vecinv;
2058      currently nothing implemented to switch this storing off
2059      in case fluxform is used since no CPP flag available).
2060    
2061    checkpoint40pre7

2078      + uses forward step for very first step of model (iter=0)
2079    o re-generated *all* output since almost all output is modified by this
2080      change (sorry but we've been putting this one off for about 2 years)
2081      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
2082        *not* regenerated since they are already out of date and I don't
2083        want to create the impression that they are suddenly working.
2084    o removed KAP stuff for DEC's
2085    o modified/added many .cvsignore files in */code and */input
2086    o added new expt "solid-body.cs-32x32x1"
2087      + this uses an alternative form of ini_curvilinear_grid.F which
2088        is not necessarily any better than the current one...
2089    
2090    checkpoint40pre4
