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

783    o Will need long integration testing.
784    checkpoint53b_pre
785    
786    o created pkg/mom_common in preparation for variable viscosity code
787    o renamed and split ini_mnc_io
788    o pkg/land: only liquid water can diffuse or run-off
789    o AIM using land: soil wetness availability account for snow
790    o added printMapIncludesZeros to EEPARMS namelist
791    
792    checkpoint53a_post
793    o restore TAMC compatiility for exf_constants.h
794      (no usage of _d in .h)
795    o Additional storing in KPP in an attempt to fix
796      TAMC problem with adjoint of KPP code.
797      (no success...)
798      Identical code works fine with TAF.
799    o Fixed verification/natl_box_adjoint experiments.
800      Initial conditions for Experiments 4 and 5 are now
801      set to "SEAICE_initialHEFF=0", which is more reasonable,
802      and hence gives results closer to that of Experiment 2.
803      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
804    
805    checkpoint53
806    o stable checkpoint with up to date adjoint
807      TLM tests only run for 1st grdchk at the moment. Its unclear if
808      this is a code problem or a problem with resetting code for g_
809      variables that is being autogenerated wrong.
810      Otherwise:
811       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
812       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
813         are both still in chaos following their security messes.
814    
815    checkpoint52n_post
816    o various build (mostly genmake2) changes including:
817      - ability to build/run more easily within Cygwin and MacOS X
818      - more complicated Makefiles with a stronger dependence on Gnu Make
819    o pkg/seaice modifications
820      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
821        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
822        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
823      - changed proxy for geostrophic velocity and updated
824        verification/lab_sea/results/* accordingly
825      - removed ADI dynamic solver from pkg/seaice
826      - replaced all occurrences of 1/CSTICE or 1/CSUICE
827        they caused a segmentation fault under certain circumstances
828      - removed unused field WATR
829    o bug fix in exf-package:
830      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
831         now reflect that.
832    o small fixes in the cal-package:
833      - set reference date to first of January for the 'model'-calendar
834      - failing of cal_CheckDate in cal_FullDate now actually results in a
835        warning
836    o small modifications in exf-package to increase flexibility:
837      - change climtempfreeze from a constant to a runtime parameter that
838        is specified in data.exf_clim (default = -1.9)
839      - introduce runtime parameter windstressmax (default = 2.0) that is
840        specified in data.exf
841    o fix in pkg/thsice:
842      - update Evap (Tsf changes) to be consistent with Latent heat flux
843      - maintain snow precipitation unchanged (even if Tsf >=0).
844     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
845    
846    checkpoint52m_post
847    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
848      this does not change any of the results, because myIter=0 in swfrac always
849      lead to jwtype=2 (the default anyway), but the call makes little sense
850      as a default
851    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
852    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
853      atmospheric model (AIM) to use it ; add a "slab ocean" component.
854    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
855    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
856    o extending useSingleCpuIO option to work with new exch2 I/O format
857      - old-style, missing-tile I/O is still accessible by defining CPP
858        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
859    o monitor package can write to NetCDF files and/or STDOUT
860    o fix re-definition bug in MNC_GRID_INIT_ALL()
861    o doc/api_reference added
862      - a framework for building an API Reference Manual using all
863        the "protex" comments embedded in the code
864      - see pkg/generic_advdiff, pkg/mnc for examples
865    o MNC:
866      - make myThid the last argument for all subroutines
867      - new default for the grid files: NO halos
868      - add useMNC and other run-time flags
869      - separate per-file-group handling of the unlimited dimension
870      - early initialization of MNC w/ flags read at the eeboot stage
871        and lookup tables set in initialize_fixed
872      - write all MNC output to a freshly-created directory
873    o thermodynamics sea-ice (thsice) is now tested with testreport.
874    o test exp. advect_cs: use the standard cs32 grid ; update output.
875    o Added functionality to grdchk:
876      pick global i,j,k position (or nearest wet) where to perform check.
877    
878    checkpoint52l_post
879    o new land formulation:
880      a) use ground enthalpy as prognostic variable to ensure exact
881         energy conservation.
882      b) account for water temperature and for latent heat of freezing
883         in all processes (rain, run-off, ground storage)
884      c) compute surface and ground temperature implicitly.
885    o aim_v23 modification for new land model:
886      a) Treat separately land / ocean / sea-ice surface fluxes
887         to allow implicit computation of land & sea-ice surface temp.
888      b) add snow precipitation.
889    checkpoint52l_pre
890    
891    o fix problem (when 1 tile is empty) in min/max monitor.
892    o fix bug in timeAve (u,vZetatave in common block)
893    o no restoring terms under ice for pkg/seaice
894    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
895    o bug fix for pkg/seaice pickups
896    o change MNC call locations and add coordinate attributes
897    o mask vorticity at the corner ; affects global_ocean.cs output
898    o fix ini_curvilinear_grid ; test CS experiments with mpi
899    o aim.5l_cs: modify sea-ice fraction input file ; update output
900    o exf: Adding simple range check routine for exf fields after read
901    
902    checkpoint52k_post
903    o removed top-level directory "diags"
904      - we migrated these functions to pkg/timeave a long time ago
905    o fixed bug introduced in pkg/monitor
906    o accuracy ctrlprec = 32 insuffient for gradient checks using
907      averaged fields (I/O via cost_averages)
908      -> use ctrl.h in active_file*.F to control I/O precision.
909    o paramter list of CALL ADTHE_MAIN_LOOP
910    o added initial do_the_model_io to ecco
911    o set all ...Freq to zero after cost_final
912      taveFreq, dumpFreq, pChkptFreq
913    o MAIN and ECCO differentiability restored
914    
915    checkpoint52j_post
916    o fix nchklev in tamc.h for global_ocean...
917    o Bringing flow and store directives up-to-date
918    o Really weird thing!
919      call do_the_model_io from the_main_loop with parameters
920      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
921      TAF places a faulty re-call of initialise_varia
922      after cost_final call which should not be there!
923    checkpoint52j_pre
924    
925    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
926      error messages
927    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
928    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
929      debug output
930    o modfied mdsio_writefield.F to handle non-global files under exch2
931    o update AIM Cubed-Sphere exp (aim.5l_cs):
932      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
933    o update AIM Equatorial Channel exp:
934      use standard aim_v23 pkg and change the SST fields to be more realistic.
935    o globalFile now works with exch2
936    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
937      mon_vort3.F to make exch2 friendly with >1 tile per cube face
938    o limit timeave output for hi-res integrations
939    
940    checkpoint52i_post
941    o removed CPP_EEOPTIONS.h from verification/*/code
942    o updated the tiling for global_ocean_pressure
943    checkpoint52i_pre
944    
945    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
946      the old pkg/aim).
947    
948    checkpoint52h_pre
949    o shortened offending lines in exch2_send_rx?.template
950    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
951    o genmake2: add build & execute test for NetCDF code
952    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
953      old grid files, moved CPP_EEMACROS.h to pkg/exch2
954    o added useSingleCPUIO flag to monitor.F and mon_out.F
955    o added temporary hack for sea-ice dynamics on the cube:
956      metric terms are ignored and it is assumed that
957      there is no sea-ice on cube faces 1, 2, 4, and 5.
958    
959    checkpoint52f_post
960    o added exch2 cube routines to pkg/exch2
961    o modified hs94.cs-32x32x5 to use it
962    o added new grid files to hs94.cs-32x32x5
963    checkpoint52f_pre
964    
965    checkpoint52e_post
966    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
967      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
968    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
969      to work with implicit vertical advection and AB ;
970    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
971    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
972     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
973    checkpoint52e_pre
974    
975    o fix bug in impldiff when Nr=1 or Nr=2.
976    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
977    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
978    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
979      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
980    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
981    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
982    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
983    
984    checkpoint52d_post
985    o re-tiled many expts to allow comparison in multi-processor mode
986      - updated output accordingly
987      - changed hs94.128x64x5 to use intial T from file rather than use the
988        random number generator
989    o add infrastructure in model routines for fizhi and gridalt packages
990    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
991    o changes to permit hi-res, cubed-sphere, configuration
992      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
993      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
994      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
995        of surface winds for the cube
996      (A verification experiment, based on global_ocean.cs32x15, but with
997       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
998       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
999       complete with example surface forcing files and matlab scripts to look
1000       at the output and compare it with that of global_ocean.cs32x15.)
1001    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1002       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1003       to conform to the common rule.
1004    o check-in the first version of the coupler + interfaces for multi-components
1005       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1006       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1007       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1008       - ocean and atmos. share the same horizontal grid (no interpolation).
1009       - exchanges between component and coupler is done in forward_step
1010    o new verification experiment, cpl_aim+ocn:
1011       coupled ocean - AIM atmosphere on cs32 grid.
1012    
1013    checkpoint52d_pre
1014    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1015    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1016    
1017    checkpoint52c_post
1018    o Fixing OPTIONS files for use of exf:
1019      - ALLOW_ECCO not needed
1020      - ECCO_CPPOPTIONS.h should not be included from
1021        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1022        as has been the case in the past
1023      - All cal/exf related options are currently set in
1024        single header file. Should remain so until we
1025        agree on a consistent new policy.
1026    o Removed all CPP options for cal package.
1027      cal has no more CPP options.
1028    o modified STOREs in GAD_ADVECTION
1029    o corrected key comp. for passkey
1030    
1031    checkpoint52b_post
1032    o new version: "thsice" of thermodynamic sea-ice pkg:
1033     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1034     - modify fluxes but do not change theta directly;
1035     - light cleaning of bulk_force pkg (still needed with thsice).
1036     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1037       + output_thsice.txt to test thsice & bulk_force pkgs.
1038    o put back grid & coriolis monitor output.
1039    checkpoint52b_pre
1040    
1041    o call "do_the_model_io" at the beginning (=> dump initial state)
1042    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1043    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1044      (need info on NUMBER_OF_PTRACERS)
1045    o missing PTRACERS headers in some routines
1046    o default tamc.h in pkg/autodiff supposed to crash
1047      to ensure proper customization
1048    
1049    checkpoint52a_post
1050    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1051      - moved surfaceTendencyTice from pkg/seaice to main code
1052      - subroutine FREEZE_SURFACE now limits only surface temperature
1053        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1054        => new output.txt for global_ocean.cs32x15 & global_with_exf
1055      - keep the old version of FREEZE for backward compatibility;
1056        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1057      - corresponding modifs for TAF directives
1058    o added surface flux output variables to TIMEAVE_STATVARS
1059    o time-averaged output for pkg/ptracers
1060    o fix problem with ECCO-related divided adjoint
1061      snapshot file was missing some ad-variables,
1062      but no warning issued by TAF
1063    
1064    checkpoint52a_pre
1065    o some bug fixes for #undef REAL4_IS_SLOW
1066    
1067    checkpoint52 = ecco_c52_e35
1068    o after testing adjoints of checkpoint51u_post
1069    
1070    checkpoint51u_post
1071    o this is the post-merge tag of the ecco-branch
1072      (needs another clean checkout and re-testing)
1073    o various natl_box_adjoint configs and results
1074      but no input fields
1075    o obcs adjoint not yet merged!
1076    o adding ECCO global 1x1 and 2x2 degree configs
1077    o updated/extended some store directives for seaice
1078    o pkg/ecco now containes ecco-specific part of cost function
1079    o top level routines the_main_loop, forward_step
1080      supersede those in model/src/
1081      previous input data.cost now in data.ecco
1082      (new namelist ecco_cost_nml)
1083    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1084    
1085    checkpoint51t_post
1086    o this is the pre-merge tag of the ecco-branch
1087    
1088    checkpoint51s_post
1089    o cleanup: removed various obsolete #define-s
1090    o pkg/grdchk
1091      - renamed 'ph-grd 3' to 'grad-res'
1092      - merged from ecco-branch
1093        (remaining bug fixes for obcs gradient checks)
1094      - additional high-precision output for testreport
1095        (grep for 'precision_grdchk_result')
1096    
1097    checkpoint51r_post
1098    o cleaned up or removed CPP_OPTIONS.h files
1099    o updated results for some of the tests to reflect the new
1100      optfiles (-ieee: -O0 instead of -O3)
1101    
1102    checkpoint51q_post
1103    o cd_code:
1104      - moved cd_scheme.F -> cd_code_scheme.F
1105      - separate read_checkpoint from cd_code_ini_vars.F
1106      - separated cd_code part from write_checkpoint
1107      - updated AD_SOURCE, generated .flow
1108      - added CD_CODE_VARS.h to the_main_loop
1109      - Moving cd_code specific store dir.s to pkg/cd_code
1110    o ctrl package totally restructured
1111      - pack/unpack now optional and decoupled from
1112        xx_/adxx_ I/O
1113      - ctrl_pack/unpack cleaned
1114        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1115      - confined inclusion of AD_CONFIG.h to where necessary.
1116    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1117    
1118    checkpoint51p_post
1119    o create initial cd_code package
1120      - WARNING: the initialization of fields within packages
1121        is broken because INI_FIELDS (where READ_CHECKPOINT is
1122        called) is called *before* PACKAGES_INIT_VARIABLES.
1123        This seems to be backwards since
1124        1) its important to initially zero the entire field including
1125           the "halo" region
1126        2) zeroing needs to be done *before* reading pickup info
1127           and the pickup call might or might not happen in any
1128           particular run
1129      - this needs an overhaul for R2
1130    o cleanup verification/*/code/GMREDI_OPTIONS.h
1131    o cleanup testreport
1132    
1133    checkpoint51o_post
1134    o bringing AD-related verif's up to date with genmake2
1135      - carbon/
1136      - global_ocean.90x40x15/
1137      - hs.94.1x64x5/
1138      - (front_relax/ )
1139    o (more) consistent directory structure for AD-related verif.'s
1140    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
1141    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1142    o bug fix in find_alpha.F for MDJWF:
1143      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1144        change rho -> rho-rhoConst
1145      - replace call find_rho to find_rhonum
1146    o initialisation of rFlx extended to full array (required by TAF)

1296      - debLevB: equivalent to current debugMode=.TRUE.
1297    o introducing pathname variable mdsioLocalDir for mdsio
1298      that can be specified at runtime
1299      (relevant for cluster I/O to local disk)
1300    `
1301    >>>checkpoint51b_post

1308    o made ptracers_forcing same as external_forcing_s
1309    o added verification for adjoint with ptracers
1310      - adm. grdchk fail so far
1311      - tlm. grdchk OK
1312      - checked tapelev/comlev recomputations: OK
1313    <<<checkpoint51b_pre

1321    
1322    checkpoint51
1323    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1324      - autodiff, ctrl, exf, grdchk, seaice
1325      kept separate packages
1326      - cost, ecco, obcs
1327    o updating verification/internal_wave, verification/lab_sea
1328      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1329    
1330    checkpoint50i_post
1331    o Preparing next differentiable checkpoint and sync
1332      of MAIN vs. ecco-branch
1333      - 1st step: this one is differentiable
1334      - 2nd step: next(! not this) checkpoint will have updated packages
1335                  from ecco-branch)
1336    
1337    checkpoint50h_post
1338    o new package "land": provide surface BC for AIM.
1339    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1340    o AIM: use true log-P extrapolation for near surface temp (= as in

1342    o New variable in PARM03 for more flexible pickups
1343    o somewhat cleaned package initialisation sequence for
1344      ctrl/ cost/ ecco/ in packages_... routines
1345    
1346    checkpoint50g_post
1347    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1348      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1349      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1350        made the default because of faster convergence than ADI
1351    
1352    checkpoint50f_post
1353    o exf totally restructured
1354      - replaced all exf_set_ routines by one generic exf_set_gen.F
1355        and made sure it's still differentiable
1356      - split exf_getffields.F into new exf_bulkformulae.F
1357      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1358      - updated adjoint/makefile and relevant verif. accordingly
1359

1369    
1370    checkpoint50e_post
1371    o make KPP work with PTRACERS
1372     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1373       nearly a copy of kpp_transport_s
1374     - there is no analogue to SurfaceTendencyS, so I have to use
1375       gPtr(of the surface layer) instead
1376    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1377    checkpoint50e_pre
1378    
1379    checkpoint50d_post
1380    o change kpp output from multiple-record state files to single-record state
1381      files analogous to write_state.F
1382    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1383      analogous to the cg2d-related output.
1384    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1385      so that writing to internal file fn (with length 512) fails.
1386    checkpoint50d_pre
1387    
1388    checkpoint50c_post
1389    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1390    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1391    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1392    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1393    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1394    
1395    checkpoint50c_pre
1396    Merging from release1_p13:
1397    o bug fix for pkg/seaice dynamic solver
1398    o Added SEAICE_initialHEFF to pkg/seaice
1399    
1400    checkpoint50b_post
1401    o store u*,v* in gU,V instead of in guNm1,gvNm1
1402    o in order to put the momForcing out of the Adams-Bashforth:
1403      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1404      to timestep.F
1405    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1406    o re-generate output for highly sensitive test-exp:
1407       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1408    
1409    checkpoint50b_pre
1410    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1411    o corrected CPP option mismatch in exf_Bulk... functions for case
1412      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1413    
1414    checkpoint50a_post
1415    o Bug fix for merging between c50 and KPP.
1416      ikey was passed from thermodynamics to kpp_calc via
1417      common block rather than being recomputed in kpp_calc,
1418      in contradiction with new key itdkey.
1419      New key ikppkey created, and tamc.h headers updated.
1420    
1421    checkpoint50
1422    - 2nd step of merge with ecco-branch:
1423      merge changes in ecco-branch back into main trunk
1424    - bug fix in find_alpha
1425    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1426    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1427    - merged some sliced AD support routines
1428    
1429    checkpoint49
1430    merged from ecco-branch:
1431    o exf:
1432      - Enable initialisation of forcing fields to constant
1433        (runtime) values.
1434      - in exf_getffields.F
1435        Reduce i-/j-loop to interior domain, discarding overlaps.
1436        That also fixes wrong TAF-key computations for key_1, key_2
1437        with bulf formulae.
1438      - exf_init.F modify #ifdef for exf_init_evap
1439      - exf_getffieldrec.F, ctrl_getrec.F
1440        The following INT-usages are not safe:
1441          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1442          fldcount = int(fldsecs/fldperiod) + 1
1443        and were modified.
1444    o autodiff: checkpoint_lev...
1445      - updated storing for bulk formulae (some arrays were missing)
1446      - added state for seaice package
1447      - synchronized with main branch
1448    o DIVA:
1449      Modif.s in
1450      - the_main_loop.F
1451      - the_model_main.F
1452      and added cost_final_restore.F cost_final_store.F
1453      o With these changes, it is possible to fully separate
1454        the first forward run to compute the cost function (mdthe_main_loop)
1455        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1456        into separate model executions.
1457        This enables better tuning of DIVA to given queue sizes.
1458      o Loss of cost function value in consecutive DIVA runs is
1459        fixed by storing to 'costfinal' file.
1460      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1461        beginning/end of adjoint integration is accounted for.
1462      The current changes apply to TAF-1.4.26.
1463      TAF has one remaining bug, requiring one manual change
1464      (see MITgcm manual).
1465    o cal: synchronized between MAIN and ecco-branch
1466    
1467    checkpoint48i_post
1468    o Changes to restore differentiability of code w.r.t. previous tag
1469      (mostly adding new routines to make list and replacing
1470      pressure by totPhiHyd).
1471    o Updated and merged grdchk package
1472      - has both ADM and TLM checks
1473      - works for single- and multi-proc.
1474      - output cleaned
1475      - worked successfully for parallel DIVA
1476    o genmake:
1477      - Adding -platform=SP4
1478      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1479    o Modif. for DIVA:
1480      ctrl_unpack should not be called in intermediate DIVA interval.
1481      (similar thing would apply for active files such as
1482      tbar, sbar, psbar, which should not be reinitialised;
1483      only relevant for ecco-branch)
1484    
1485    checkpoint48h_post
1486    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1487    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1488    o Added SEAICE_initialHEFF to pkg/seaice
1489    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1490    
1491    checkpoint48g_post
1492    --- EOS:
1493    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1494      store total Potential in totPhyHyd for diagnostics & EOS.
1495    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1496    --- Pressure/geopotential gradient:
1497    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1498    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1499      ( changes results of global_ocean_pressure )
1500    o NLFS + z-coord.: add eta*Rho' contribution.
1501    o accurate phiHyd when using interface-W at the middle between 2 centers
1502     ( changes results of ideal_2D_oce )
1503    o includes r* 2nd term in potential gradient.
1504    
1505    checkpoint48f_post
1506    Merging from release1_p12:

1513      (SBO) core products, including oceanic mass, center-of-mass,
1514      angular, and bottom pressure (see pkg/sbo/README.sbo).
1515    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1516      to avoid negative values in shallow regions.
1517      - updated verification/natl_box/results/output.txt
1518      - updated verification/lab_sea/results/output.txt
1519    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1520    o Added useSingleCpuIO option (see PARAMS.h).
1521    o Updated useSingleCpuIO option in mdsio_writefield.F to
1522      work with multi-field files, e.g., for single-file pickup.
1523    o pkg/seaice:
1524      - bug fix in growth.F: QNET for no shortwave case

1535    o dynamics: change definition of computational domain & adapt mom_fluxform
1536      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1537    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1538        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1539        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1540        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1541        inverted_barometer solid-body.cs-32x32x1
1542      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1543    
1544    checkpoint48d_post
1545    o in preparation for r*:
1546     a) use pre-computed gradient of hydrostatic potential:
1547        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1548     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1549        => affects results of glob_oce_pressure (different truncation error)  
1550      update output.txt of ideal_2D_oce & global_ocean_pressure
1551    
1552    checkpoint48d_pre
1553    o in preparation for r*:
1554      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1555      pass the 2 comp. of the grad. as arguments to momentum S/R.
1556      but for the moment, only used if it does not change the results.
1557    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1558    
1559    checkpoint48c_post
1560    Modifications in treatment of initial flux forcing controls
1561    to avoid extra storing of flux fields.
1562    
1563    checkpoint48c_pre
1564    o Added tidal_basin_2d experiment (currently 1D!)
1565    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1566    
1567    checkpoint48b_post
1568    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1569     (modification to pressure gradient not yet implemented)
1570    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1571      (for U & V) that are used for vertical advection of momentum.
1572    
1573    checkpoint48a_post
1574    o In preparation for r*, use temp. array to compute vertical transport
1575       in flux-form momentum pkg. => change results of few test-exp.
1576      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1577                        lab_sea, natl_box & plume_on_slope
1578    
1579    checkpoint48
1580    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1581    
1582    checkpoint47j_post
1583    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1584    o moved adexch from forward_step to addummy_in_stepping
1585    o added exch in ctrl_map_...
1586    o aveFreq.=0. at end of cost_final to avoid overwrite in
1587      reverse checkpointing loop
1588    o Yet more changes in gmredi:
1589      * adgmredi_calc_tensor
1590        avoiding all recomputation of gmredi_slope_limit
1591      * adgmredi_x/y/rtransport
1592        added flag for excessive storing to avoid recomp. of
1593        u/v/rtans, dTdx/y/z
1594        -> this is not really necessary and very memory-consuming
1595      * adgmredi_slope_psi:
1596        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1597      * gmredi_slope_limit
1598        re-activated full calculation of taperfct for case 'ac02'
1599    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1600    
1601    checkpoint47i_post
1602    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1603    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1604      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1605    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1606    o gmredi: fix few bugs.
1607    
1608    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1609    This will be a good checkpoint to plug into the ecco-branch.
1610    o few modif.'s to get latest version adjointed
1611      (mainly kick out code in ini_linear_phisurf)
1612    o modif's to run adjoint with exactConserv
1613    o case GM_BOLUS_ADVEC should be cleaned
1614      S/R gmredi_slope_psi should be cleaned
1615    o verification/carbon now has exactConserv=.TRUE.
1616    
1617    checkpoint47g_post
1618    o time-average AIM output: becomes independent from statvars time-average
1619      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1620    o After TAF bug fix:
1621      Tested adjoint of gmredi package.
1622      Tests were done with checkpoint47 rather than with latest
1623      checkpoint47f_post since the latter is broken for the adjoint
1624      verification/carbon/ contains both ADM and TLM gradient checks.
1625    Here they are, before they get changed/lost/stolen.
1626    Mostly modif.'s to fix numerical sensitivities.
1627    Gradient checks OK for
1628    - GM_taper_scheme:
1629      * clipping
1630      * ac02
1631      * linear
1632      * glw91
1633      * dm95
1634      * ldd97
1635    - GMREDI_OPTIONS:
1636      * GM_VISBECK_VARIABLE_K
1637      * GM_NON_UNITY_DIAGONAL
1638      * GM_EXTRA_DIAGONAL
1639      * GM_BOLUS_ADVEC
1640    in conjunction with data.gmredi parameters to be checked in
1641    in a few minutes under verification/carbon/code/
1642    
1643    checkpoint47f_post
1644    Merging from release1_p10:
1645    o modifications for using pkg/exf with pkg/seaice
1646      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1647        and SEAICE_EXTERNAL_FLUXES
1648      - pkg/exf CPP options EXF_READ_EVAP and
1649        EXF_NO_BULK_COMPUTATIONS
1650      - usage examples are Experiments 8 and 9 in
1651        verification/lab_sea/README
1652      - verification/lab_sea default experiment now uses
1653        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1654    
1655    checkpoint47e_post
1656    o created a tag prior to creating a branch
1657    
1658    checkpoint47d_post
1659    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1660      at the bottom boundary had an erroneous half slip boundary condition
1661    o added bottom drag and no slip boundary condition capabilities to
1662      oceanic pressure coordinates code
1663    o added new verification experiment global_ocean_pressure, this experiment is
1664      also described in the tutorial section of the manual
1665    checkpoint47d_pre
1666    
1667    checkpoint47c_post
1668    o Added a verification experiment for a global cubed-sphere ocean run
1669      -  verification/global_ocean.cubed32x32x30
1670      -  uses pkg/therm_seaice and pkg/bulk_forcing
1671    
1672    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1673    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1674      when using P-coordinate; only implemented for atmospheric config.
1675    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1676      NOTES: requires option NONLIN_FRSURF to be "#define".
1677    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1678    
1679    checkpoint47b_post
1680    Merging from release1_p9:
1681    o pkg/seaice
1682      - removed GOTO's and added taf directives
1683      - double precision constants to reduce the g77 (Linux)
1684        to F77 (SGI) differences reported in release1_p8
1685    o tools/genmake
1686      - added SGI options
1687    o verification/testscript
1688      - updated to that of checkpoint47a_post
1689    o verification/global_ocean.90x40x15/input/eedata
1690      - modified for SGI f77 compatibility
1691    o verification/lab_sea
1692      - added description of sea-ice model
1693      - added missing matlab routines
1694      - added test of thermodynamics parallelization
1695    
1696    checkpoint47a_post
1697    o new pkg: aim_v23
1698     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1699       for now, keep the same surface forcing as before.
1700     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1701     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1702     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1703    o add diagnostic of surface correction term in monitor output
1704    
1705    o bulk_force and therm_seaice
1706    - Two packages:  bulk_force (Bulk forcing)
1707      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1708    - Earlier integration from Stephaine Dutkiewicz
1709      and Patrick Heimbach.
1710    - Two ifdef statements for compile time,
1711       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1712    
1713    checkpoint47
1714    differentiable version of checkpoint46n_post
1715    o bug fix in quasihydrostaticterms
1716    o * "clean" adjoint code (in terms of extensive recomputations)
1717        can now be obtained for all GMREDI options (i.e. for
1718        - GM_VISBECK_VARIABLE_K
1719        - GM_NON_UNITY_DIAGONAL
1720        - GM_EXTRA_DIAGONAL
1721        - GM_BOLUS_ADVEC )
1722      * However, wrong gradient check problem remains unsolved.
1723      * New CPP options have been introduced for different
1724        tapering schemes
1725    o external_fields_load now part of differentiation list
1726    o pressure needs multiple storing;
1727      would be nice to have store_pressure at beginning or
1728      end of forward_step, e.g. by having phiHyd global (5-dim.)
1729      (NB: pressure is needed for certain cases in find_rho,
1730      which is also invoked through convective_adjustment).
1731    o recomputations in find_rho for cases
1732     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1733    o #define ATMOSPHERIC_LOADING should be differentiable
1734    o ini_forcing shifted to begining of initialise_varia
1735    o Incorporating QNVS line search routines into MITgcm
1736      (this is separate code, and therefore not under pkg)
1737      lsopt/, optim/
1738    o Updated verification/carbon/
1739      - #define GM_VISBECK_VARIABLE_K
1740      - GM_taper_scheme    = 'ldd97'    
1741    
1742    checkpoint46n_post
1743    Merging from release1_p8:
1744    o verification/natl_box:
1745      updating new external_fields_load routine
1746    o New package: pkg/seaice
1747      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1748      The sea-ice code is based on Hibler (1979-1980).
1749      Two sea-ice dynamic solvers, ADI and LSR, are included.
1750      In addition to computing prognostic sea-ice variables and diagnosing
1751      the forcing/external data fields that drive the ocean model,
1752      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1753      The implied surface heat flux is then stored in variable
1754      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1755      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1756      non-local transport term.  Because this call precedes model
1757      thermodynamics, temperature under sea-ice may not be "exactly" at
1758      the freezing point by the time theta is dumped or time-averaged.
1759      N.B.: fairly large differences in accuracy occur across
1760            different platforms/compilers; comparison between
1761            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1762            generated output gives:
1763       T           S           U           V
1764      C D M    c        m  s        m  s        m  s        m  s
1765      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
1766      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
1767      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
1768    
1769      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1770    o GAD:
1771      - generated new common blocks to account for call of
1772        same gad routines with differing traceridentities
1773        (needed to modify tracerIdentity indices in GAD.h)
1774      - generated separate common blocks for case useCubedSphereExchange
1775        (Department of Futurology)
1776      - parameter lists to gmredi_?transport: added tracerIdentity
1777      - added new key indices to tamc.h
1778    o external_fields_load:
1779      - added this routine to TAF list
1780      - needed to make some common blocks global and additional storing
1781        along the same lines as exf package (checkpoint_lev?_directives.h)
1782    o exf:
1783      updated external forcing package
1784      - bug fixes carried over from ecco-branch
1785        (missing OBCS_OPTIONS.h in two routines)
1786      - enable easy to use "no forcing".
1787      - added exf I/O for atmospheric loading
1788      - added exf I/O for runoff data
1789      - transfered scaling between exf <-> MITgcm to exf namelist
1790    o Adding new verification experiment global_with_exf.
1791      This verification experiment is almost identical to the
1792      global_ocean.90x40x15 experiment, except that it uses
1793      the exf (and cal) package instead of the
1794      external_fields_load routine (cf README file).
1795    
1796    checkpoint46m_post
1797    o modified testscript to return -- when there are no lines of "%MON" output
1798    o added new flag "quasiHydrostatic" for QH mode
1799      and new routine quasihydrostaticterms()
1800    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1801      New routine: mom_u_coriolis_nh()
1802    o fixed sign of non-hydrostatic metric terms in u and v equations.
1803      Depend on correct sign of gravitySign.
1804    o added work.pc* to .cvsignore in aim directories using ifc
1805    o introduced flag for controllin non-hydrostatic metric terms
1806    o removed gravitySign from PARM04
1807    o switched to g77/ifc from pgf77 in aim experiments
1808    
1809    checkpoint46l_post
1810    o made convective adjustment work with pressure coordinates:
1811     - changed the direction of k-loop in convective_adjustment.F for the
1812       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1813     - adjusted the reference pressure k-index in convective_adjustment.F
1814     - adjusted the convection condition in convect.F (in analogy to
1815       calc_ivdc.F)
1816     - convective_adjustment no longer computes anything on the halos
1817     - removed the warnings about negative salinity from find_rho.F and
1818       find_alpha.F; instead the new routine look_for_neg_salinity, called
1819       at the beginning of find_rho, find_alpha, and find_beta, does a
1820       check of the entire slice, if CPP-option
1821       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1822    checkpoint46l_pre
1823    
1824    checkpoint46k_post
1825    o fixed the verification/global_ocean.90x40x15 experiment:
1826     - new bathymetry (the world according to A., JMC, and M.)
1827     - new initial fields and forcing fields (*.bin files)
1828     - new POLY3.COEFFS (for the next release one should switch to a full
1829       equation of state: JMD95P or MDJWF)
1830     - fixed several errors and redundancies in the data file
1831     - experiment uses looped cells
1832     - added matlab directory with diagnostic scripts for plotting of output
1833    
1834    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1835     - read AIM physics parameters from a file (data.aimphys)
1836     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1837    
1838    checkpoint46j_post
1839    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1840    o move wVel computation at the end of the time step, in S/R integr_continuity
1841    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1842    o update timeave pkg for wVel diagnostic.
1843    checkpoint46j_pre
1844    
1845    checkpoint46i_post
1846    o Clean up AIM package (and keep the results unchanged):
1847      include CPP_OPTION and use IMPLICT NONE in all routines ;
1848      declare all the variables _RL ; use _d 0 for all numerical constants.
1849      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1850    
1851    checkpoint46h_post
1852    o cleaned up the use of rhoNil and rhoConst.
1853      - rhoNil should only appear in the LINEAR equation of state, everywhere
1854        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1855        and the dynamical equations are all divided by rhoConst
1856    o introduced new parameter rhoConstFresh, a reference density of fresh
1857      water, to remove the fresh water flux's dependence on rhoNil. The default
1858      value is 999.8 kg/m^3
1859    o cleanup up external_forcing.F and external_forcing_surf.F
1860      - can now be used by both OCEANIC and OCEANICP
1861    checkpoint46h_pre
1862    
1863     Added code to convert surface volume flux (fresh water) into
1864     a mass flux when using P coordinates in the ocean (OCEANICP).
1865     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1866    
1867    checkpoint46g_post
1868    o Include a new diagnostic variable phiHydLow for the ocean model
1869      - in z-coordinates, it is the bottom pressure anomaly
1870      - in p-coordinates, it is the sea surface elevation
1871      - in both cases, these variable have global drift, reflecting the mass
1872        drift in z-coordinates and the volume drift in p-coordinates
1873      - included time averaging for phiHydLow, be aware of the drift!
1874    o depth-dependent computation of Bo_surf for pressure coordinates
1875      in the ocean (buoyancyRelation='OCEANICP')
1876      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1877        Theta, Salinity, and Pressure in the parameter list. This routine is
1878        presently contained in find_rho.F. This routine does not give the
1879        correct density for 'POLY3', which would be a z-dependent reference
1880        density.
1881    o cleaned up find_rho
1882      - removed obsolete 'eqn' from the parameter list.
1883    o added two new verification experiments: gop and goz
1884      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1885    checkpoint46g_pre
1886    
1887    checkpoint46f_post
1888    o Enable tangent linear (forward mode) gradient checks:
1889      - extended active file handling to g_... files
1890      - added TANGENT_SIMULATION to theSimulationMode
1891      - extended grdchk package accordingly
1892    o added tangent linear setup in verification/carbon/code_ftl
1893    o added adjoint setup in verification/front_relax/code_ad
1894    
1895    checkpoint46e_post
1896    o Added new equation of state -> MDJWF
1897      - EOS of McDougall et al., 2002, JAOT, submitted
1898      - caveat: the equation of state is only valid for a smaller (more
1899        realistic?) range of values than JMD95P/Z and UNESCO
1900      - added masks to the calculation of pressure in store_pressure
1901      - added more check values for density in check_eos (ini_eos.F), some of
1902        the old check values are out of the range of the MDJWF-eos, so don't
1903        expect perfect matches for those
1904    checkpoint46e_pre
1905    
1906    checkpoint46d_post
1907    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1908      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1909      case of pressure coordinates. eosType='JMD95Z' in
1910      combination with buoyancyRelation='OCEANICP' now causes an error.
1911    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1912      in find_alpha/beta.
1913    checkpoint46d_pre
1914    
1915    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1916      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1917    
1918    checkpoint46c_post
1919    o Changes necessary for ocean in p-coordinates
1920     -  Added new buoyancy relation = 'OCEANICP'
1921     -  Added new parameters = gravitySign (this used to be contained inside
1922        the factor dRdZ which I added when we first switched to R coordinates).
1923     X GM/Redi is not compatible (yet)
1924     X bottom drag and no-slip need to be debugged.
1925    checkpoint46c_pre
1926    
1927    checkpoint46b_post
1928    o Added new equation of state -> JMD95Z and JMD95P
1929      - EOS of Jackett and McDougall, 1995, JAOT
1930      - moved all EOS parameters into EOS.h
1931      - new routines ini_eos.F, store_pressure.F
