4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
8      end-run around the C/Fortran linking horror in eesup/src/timers.F
9    o added pkg/runclock: allows user to terminate run based on wall clock
10    o added non-hydrostatic scaling parameter: nh_am2
11    o pkg/my82: futile attempt to make results compiler-independent by adding
12      some "_d 0", etc. no effect.
13    o for mnc output, fill the 'T' coordinate var with myTime and create a
14      separate 'iter' variable for iteration count
15    o pkg/diagnostics:
16      add new capability: output of Global/Regional & per-level statistics ;
17      tested against monitor output (including land & thSIce) on various exp.
18    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
19    
20    checkpoint57h_done
21      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
22      data.diagnostics, data.gchem, data.ptracers) is done.
23    
24    o pkg/diagnostics: prepare for Global/Regional statistics.
25      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
26    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
27      and rename it: DIFFERENT_MULTIPLE
28    
29    checkpoint57h_post
30    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
31    o pkg/diagnostics: change output frequency, now in seconds (instead
32      of Nb of iterations). This requires to change data.diagnostics.
33    checkpoint57h_pre
34    
35    o in mnc, let the user create the output dir if both mnc_outdir_date
36      and mnc_outdir_num are false
37    o add fflags() to pkg/diagnostics which allows one to specify, on a
38      per-file basis, the file precision [default behavior is unchanged]
39    o added diagnostics to pkg/kpp, including computation of mixed layer
40      depth based on a temperature/density criterion
41    o updated verification/natl_box to test the new pkg/kpp diagnostics
42    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
43    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
44    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
45      not mnc -- this mistake was found by JMC and is now corrected
46    
47    checkpoint57g_post
48    o add Adams-Bashforth 3rd Order time stepping:
49      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
50      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
51    checkpoint57g_pre
52    
53    o make lambda[Theta,Salt]ClimRelax spatially varying
54      (default remains spatially uniform constant based on tau)
55    o added new control variables
56      * init. uVel, vVel, etanN
57      * lambda[Theta,Salt]ClimRelax
58    o separate masks used for ctrl_pack/unpack 'from write_grid' output
59      (suggested by G. Forget)
60    
61    checkpoint57f_post
62    o add parameter "baseTime" = model base time = time at iteration zero
63      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
64      account for baseTime shift
65    o move Coriolis arrays from PARAMS.h to GRID.h
66    checkpoint57f_pre
67    
68    o mnc-ifying the seaice package
69    o introduced an alternative length scale calculation for use in the limiting
70      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
71    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
72    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
73      as well as grad(vort3).  Made it compatible with both approximate form
74      for the cubed sphere and full form of these gradients.  Added flag
75      useFullLeith to select between approximate and full form.  
76    o add "d0" in getcon.F to reduce differences between compilers/platforms
77      update output.txt of exp. fizhi-gridalt-hs
78    o change port_rand funtion to allow to set the seed.
79    o fix obscure MNC bug involving conversion between reals and integers
80      - it caused no problems with certain (eg. gcc, ifc) compilers but the
81        new version is now more standards-compliant
82    o adjoint-related modifications
83      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
84      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
85      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
86    
87    checkpoint57e_post
88    o Adding eddy stress controls a la Ferreira et al.
89    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
90    
91    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
92      update output.txt of exp. fizhi-gridalt-hs
93    o add more "Z" dimensions and associated coordinate vars to MNC
94    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
95    o parameter calendarDumps: when set, approximate months (30-31 days) and years
96      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
97      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
98      months and years.  Requires pkg/cal.
99    o diagnostics: add pickup functionality
100      - off by default for backwards compatibility
101      - current version only uses MDSIO -- MNC will be added
102    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
103    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
104    
105    checkpoint57d_post
106    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
107    o modify verification/ideal_2D_oce so that it tests the creation of mnc
108      output from the diagnostics package
109    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
110    o make genmake2 more portable by using ".$FS" instead of ".f" for more
111      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
112    o add coordinate variables to the MNC output from the diagnostics package
113    o change MNC-flags default value: true when useMNC=TRUE
114    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
115      the ability (off by default) to read the grid information using MNC
116    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
117    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
118    o do snap-shot diagnostics at the middle of the time-interval (instead of
119      at the end).
120    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
121      new test for AIM with thSIce + slab-ocean
122    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
123    o move state variable diagnostics to the beginning of the time step ;
124      (note: still needs some work specially for snap-shot diagnostics)
125      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
126    
127    checkpoint57c_post
128    o Change testing option (-ieee) to get closer agreement between g77 & ifort
129    o generate new output.txt files on faulks with g77 & the new -ieee option
130    checkpoint57c_pre
131    
132    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
133      update output.txt of exp. global_ocean.90x40x15
134    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
135      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
136    o add saltFlux(+File) forcing capability with periodicExternalForcing
137    o allow to use pkg diagnostics for GM-Redi & ThSIce output
138    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
139    o improvements for the MNC output from DIAGNOSTICS:
140      - correct handling of the unlimitied dimension
141      - all dims now have associated coordinate variables
142      - variables located at U, V, and Corner ("Z") points are now written
143        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
144        *all* data points are output
145    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
146    o added pkg/seaice/seaice_monitor.F
147    o mdsio_readfield.F can now read files visible only to master MPI process.
148    o pkg/seaice: some test code for ice-modified ocean stress
149    o exf_getffields interpolation defaults to bilinear for all scalar forcing
150      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
151      spurious negative numbers for precipitation and humidity.  Will cause
152      some small numerical differences for integrations using pkg/exf/exf_interp.F.
153    o pkg/ctrl/
154      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
155        May be enabled via doPackDiag
156      *  introduce z-scaling of
157         + gradient (doZscalePack) and
158         + control (doZscaleUnpack)
159    o pkg/mdsio/
160      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
161      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
162    
163    checkpoint57b_post
164    o simplify options in diagnostics_fill arguments (remove weird combinations)
165    o fix MNC coordinate variables so that they now contain per-face index
166      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
167      general, EXCH2 grids are only aligned to a "local" coordinate system
168    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
169    o Implement instantaneous output within pkg diagnostics:
170      setting a negative frequency in data.diagnostics produces
171     "snap-shot" output (as opposed to time-average if freq > 0)
172    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
173      NOTE: change ptracer diagnostics name: use 2 characters to work with
174            more than 9 tracers. Add also diagnostics of advect & diffus flux.
175    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
176      becomes the coordinate variable for the 'T' dimension
177    o add CF-style coordinate variables to MNC
178      - just a first cut:  numbers are meaningless on the cubesphere and
179        missing along the T axis but otherwise it works!
180    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
181    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
182    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
183      this is based directly on what the model compute, so that the content of
184      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
185    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
186    o clean up build options files for SunOS, in particular
187      - remove -traditional from xmakedepend
188      - change -xarch=v9 to -xarch=native for f77
189      - restore use of make (not gmake)
190      - add CC=gcc if using g77
191    o changes per discussion of AM, JMC, & EH3 today:
192      - move redundant "grid" variables out of "state" -- in preparation of
193        creating proper CF-style coordinate variables and in recognition
194        that any/all grid variables can be easily copied (eg. w/NCO) from
195        the grid files into any of the other NetCDF files
196      - *always* output grid variables with MDSIO (this will eventually be
197        changed)
198      - output MNC grid file if useMNC is true
199    o every instance of _END_MASTER() has been found and replaced with
200      _END_MASTER( myThid ) in order to satisfy certain picky Sun
201      preprocessors
202    o re-arrange diagnostics pkg initialisation:
203     - allow each package to extend the available diagnostics list
204     - add some checking and fix small problems (multi-threaded, ...)
205     - new S/R diagnostics_fill (replace fill_diagnostics):
206       look through the short list of active diag. (instead of the long list)
207       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
208    
209    checkpoint57a_post
210    o this set of changes restores TAMC compatibility
211      tested for global_ocean.90x40x15 adjoint on trough
212      (what a pain)
213    
214    checkpoint57a_pre
215    o some modifs in tools/build_options for sunos
216    o call ctrl_pack for ctrl at end for optimcycle=0
217    
218    checkpoint57
219    o add horizontal bi-harmonic viscosity for vertical velocity
220      - new parameter viscA4W (defaults to viscA4)
221      - affects only non-hydrostatic code
222      - to be done: no-slip lateral boundary conditions
223    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
224    o implement Implicit Vertical advection for pTracers
225    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
226      (implemented also for implicit vertical diffusion & advection)
227    o OBCS: extend application of tracer open boundary conditions
228      to a strip beyond the boundary of width Olx/Oly
229    o add call monitor to TAF set of required calls (flow directives)
230      and include in natl_box_adjoint
231    o untangle a few ifdefs related to cost, ctrl, autodiff
232      untangel a few ALLOW_ECCO_OPTIMIZATION
233    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
234      (theta2, salt2 in ecco_cost_weights)
235    
236    checkpoint56c_post
237    o OBCS as control variables
238      - update ctrl_ad_diff.list, obcs_ad_diff.list
239      - remove balance of obcs controls from default
240      - fix index bug nobcs in ctrl_init
241      - fix dummy fields filen in ctrl_pack
242      - add dummy weights for obcs
243    o lsopt: comment out fort.94 output
244    o optim:
245      - remove unnecessary header files
246      - adjusted namelists
247      - add xerbla.F to Makefile
248    o exf:
249      - multiple modifications of exf_check_range
250      - unit change in exf_init_runoff from [m/year] to [m/s]
251    o mdsio:
252      - i/o-vector change debugLevel from debLevA to debLevB
253    
254    checkpoint56b_post
255    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
256      is called from DO_THE_MODEL_IO
257      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
258      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
259      - clean up PTRACERS_WRITE_TIMEAVE a little
260    o add another verification experiment that tests both the cfc-pkg and
261      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
262      reactive tendencies treated inline with regular timestepping
263    o testreport previously did a lousy job of comparing small numbers, so
264      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
265      implemented in the little c-progam tmp_cmpnum.c which is embedded in
266      testreport.
267    o ptracers_monitor: bug fix for MPI
268    
269    checkpoint56a_post
270    o GCHEM: finish reorganizating the package
271      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
272        (introduces another 3D-array for each passive tracer, but only if
273        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
274        gchemTendency is not needed because the timestep is done separately)
275      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
276      - GCHEM is now---more or less cleanly---separate from PTRACERS
277      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
278        so clear to me how that should be done in a general way.
279    o CFC: improve formatting of output in CFC_ATMOS
280    o PTRACERS:
281      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
282        that ALL experiments with ptracers enable can be checked. This makes
283        GCHEM_MONITOR obsolete.
284      - include a runtime parameter PTRACERS_monitorFreq that defaults to
285        monitorFreq
286      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
287    o add PTRACERS (PTR0[1-5]) to testreport output
288    o exf_check_range:
289      * default changed to .TRUE.
290      * will check values for niter0 if debLevA, every timestep if debLevB
291      * STOP in exf_check_range if 'out of range'
292      * range chosen generous to allow for potential extema
293      TBD: a version with stricter range
294           permitted range would be runtime parameters
295    o GMredi:
296      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
297      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
298      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
299    o GCHEM:
300      - move call to GCHEM_FORCING_SEP, so that it is now called before
301        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
302      - introduced a useGCHEM runtime flag and applied it everywhere.
303      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
304        this flag is now only visible within GCHEM-pkg routines.
305      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
306        be replaced by a 3D array that is computed before thermodynamics; for
307        this, the tracer ID iTracer had to be included into the parameter list
308        of ptracers_forcing
309      - set up forward_step to call gchem_forcing, that will replace
310        gchem_forcing_int in ptracers_forcing
311      - cleaning up
312    o small cleaning of exch2: remove files that are also in eesupp/src
313    
314    checkpoint56
315    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
316    o mnc: cleanup "full" files--fixes out-of-memory problem
317    o ECCO-GODAE
318      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
319      * fully merged and updated from SIO code
320        windstress sign change affects
321        - exf_inscal_[u/v]stress
322        - sign of xx_tau[u/v] adjustments
323        - signs in cost_scat
324      * ctrl_get_gen: avoid update of tau[u/v] for first few days
325      * natl_box_adjoint updated and compressed
326      * 2-level checkpoint switch added
327        (tested in EXP. 1 of natl_box_adjoint)
328      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
329    o SVD
330      * first complete, non-hacked version for SVD calculations
331      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
332        performed via direct access files admtlm_vector.it????
333        (via ctrl_[un]pack)
334      * optimcycle is used for ARPACK iteration counter
335        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
336      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
337        and add linear transforms where necessary
338      * controls are initial/final SST, SSS (can be extended; need to check
339        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
340    o mdsio: filename info to both stderr, stdout
341    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
342      from sign change
343    
344    checkpoint55j_post
345    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
346      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
347    o add consistent build directories and .cvsignore files to verification
348    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
349    o make all subroutines 30 or less characters in length for certain older
350      compilers to work (a thorough search only turns up two routines in
351      pkg/ptracers)
352    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
353      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
354    
355    checkpoint55i_post
356    o change arrays for total vertical diffusivity (2.D if explicit,
357      3.D if implicit) ; each ptracer uses its own background value.
358    o added mnc/NetCDF output capability to ocn_compon_interf
359      - added bits to verification/cpl_aim+ocn so that it can run on
360        ITRDA and other clusters without the mpirun "-wd" option
361    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
362      configuration
363    o give MNC the ability to create additional files rather than
364      exceeding a specified file size limit "MNC_MAX_FILESIZE"
365      - the default is just less than 2GB which is a practical limit
366        on many systems
367    o Compute the non-local term using either KPP vertical diffusivity (=default)
368       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
369    
370    checkpoint55h_post
371    o add verification test "vermix"
372    o remove all the *_ioinc flags and replace with the single global
373      outputTypesInclusive flag
374    o allow to set a vertical profile of vertical diffusivity for T & S
375    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
376    o useMNC moved from data.mnc to data.pkg
377    
378    checkpoint55g_post
379    o Renaming carbon AD experiments to comply with testreport conventions
380    o Updating adjoint of Held-Suarez hs94.1x64x5
381    o Fixing directives for non-ECCO forward_step, after ECCO directives
382      have been fixed to avoid recomp. of do_oceanic_phys
383      Works well for global_ocean.90x40x15,
384      but recomp. issue remains for carbon
385    o Updating adjoint output for natl_box_adjoint after
386      pkg/ecco has been modified (see taga c55d_post)
387    
388    checkpoint55f_post
389    o rename to timeave_init_fixed
390    
391    checkpoint55e_post
392    o some delicate re-shuffle of store directives to avoid one
393      extra call of do_oceanic_physics
394      affects ecco_the_main_loop.F, do_oceanic_physics.F
395      checkpoint_lev1_directives.h
396    o NB: this may break global_ocean adjoint temporarily,
397      but it is clear how to fix it. Will do later, need this now.
398    
399    checkpoint55d_post
400    o ECCO specific cost function terms (up-to-date with 1x1 runs)
401    o ecco_cost_weights is modified to 1x1 runs
402    o modifs to allow observations to be read in as
403      single file or yearly files
404    o enable to read exf forcing fields as either
405      single file or yearly files (flag useExfYearlyFields)
406    checkpoint55d_pre
407    
408    o switch between 2-level and 3-level checkpointing
409    o add ability of MNC to write local and "partial" (eg. 2D slices where
410      the full 3D field is never actually stored) arrays to NetCDF files
411      with the correct (that is, the complete multi-dimensional) set of
412      array indicies
413      - used in mom_vecinv() to write the diagFreq output
414      - tested (demonstrated) in verification/aim.5l_cs
415    o further mnc-ification
416      - add verification/lab_sea to the list with mnc setups
417      - fix undefined mnc v-names in cd_code
418      - add kpp to mnc output (both snapshot and timeave)
419    o non-hydrostatic code
420      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
421        in calc_gw.F
422      - defaults to viscAh
423      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
424        friction or Leith) in non-hydrostatic mode, as long as there is
425        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
426    o pkg/cost
427      extend simple cost functions to treat time mean quantities
428      (T,U,V) via cost_accumulate_state from cost_tile
429    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
430        be 2 times larger than the minimum size the advection scheme requires.
431        now get a perfect conservation of salt in advect_cs test-exp (updated)
432    o GGL90 (Gaspar's TKE mixed layer)
433      - add horizontal diffusion of TKE, requires exchanges in
434        do_fields_blocking_exchanges, horizontal diffusivity is zero by
435        default. In OPA there is no horizontal diffusion of TKE but the
436        mixing coefficients are computed from a horizontal average of TKE of
437        6 points or so. I think that diffusion has a little more physical
438        justification.
439      - clean up ggl90_calc in the hope of reducing memory usage (this hope
440        was in vain)
441      - mask tke-variable in ggl90_init
442    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
443    o fix biharmonic diffusion on CS-grid.
444    o more obcs stuff
445      - added obcs_external_fields_load as an alternative to the EXF-pkg option
446        for reading boundary values. This routine is called from
447        obcs_prescribe_read
448      - updated obcs_check
449      - changed sponge layer relaxation parameter units for days to seconds
450      - turned off sponge layer by default
451      - changed argument list of OBCS_CALC to myTime+deltaTclock
452      - fixed about 35 bugs in obcs_external_fields_load
453    
454    checkpoint55c_post
455    o obcs stuff
456      - new runtime flags useOBCSprescribe, useOBCSbalance
457      - re-arranged obcs_calc
458      - moved exf_getobcs to obcs_prescibe_read
459        obcs_prescibe_read is called after ORLANSKI stuff
460        and independent of it (executable can contain all).
461      - updated obcs_check
462      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
463        These may be necessary only if tangential velocities are
464        prescribed at OB, not sure, needs testing.
465    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
466      which simplifies the calls and passes the ifc check-bounds test
467    
468    checkpoint55b_post
469    o add a 2D scalar, Z location, exchange_2 routine.
470    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
471      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
472      affects advect_cs results (for the wrong reason): update output.txt
473    o use a more standard discretization for biharmonic viscosity ;
474     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
475      affects results of dome set-up: update output.txt
476    o fix gad_advection.F (CubedSphere part), back to version 1.23
477    o fix bug in mom_vi_del2uv.F (CubedSphere part).
478    
479    checkpoint55a_post
480    o merged code to
481      * prescribe/read time-dependent open boundaries
482        (works in conjunction with exf, cal)
483      * sponge layer code for open boundaries
484      * each boundary N/S/E/W now has its own CPP option
485        (healthy for the adjoint)
486    
487    checkpoint55
488    o up-to-date adjoint of previous breaks
489      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
490      - global_ocean_ebm: adjoint still needs fix (TLM ok)
491      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
492      - carbon: * remove tr1-related adjoint verification
493                * add ptracer as control variable
494    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
495      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
496    
497    checkpoint54f_post
498    o in verification/carbin/ remove experiment related to
499      ALLOW_PASSIVE_TRACER (array tr1 etc)
500      code_ad/ input_ad/ results_ad
501    
502    o add two new packages
503      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
504        + subject to optimization (memory)
505      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
506        + subject to reordering (many GOTOs in the original code)
507        + so far opps is called for every (i,j) point, and then operates in
508          the vertical; one may want to reorder the scheme in order operate in
509          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
510          fields)
511    o overhaul of IO so that we now have flags for MDSIO and/or MNC
512      - all verification tests compile and run with linux_ia32_g77
513      - defaults are compatible with current input files--nothing
514        should change if you were not previously using MNC
515      - MNC output has been added in numerous places (eg. timeave)
516        but there are still a few writes not yet do-able with MNC
517        (this is in progress)
518      - flags now allow for either/or/both use of MDSIO and MNC and
519        documentation will soon follow
520      - numerous small formatting cleanups for ProTeX
521    o add version info (via BUILD_INFO.h) to MNC and stdout
522    
523    checkpoint54e_post
524    o add two new packages
525      - pp81 (Packanowski and Philander, 1981), Richardson number and
526        stratification dependent mixing
527      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
528      - these scheme operate in a similar manner as KPP (without ghat, of
529        course), however there is only one diffusivity that is used for both
530        temperature and salinity (and passive tracers)ç
531    o add offline package
532    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
533      provided by Stephanie Dutkiewicz
534    o genmake2: add ability to search for C compilers and cleanup test output
535      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
536    
537    checkpoint54d_post
538    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
539    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
540      leading to additional shift by 5 days each year of integration
541       (i.e. leading to considerable offset over the years)
542    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
543    o start with no AB and no initial filtering (staggerTimeStep):
544      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
545    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
546      (external loading & cpl import/export stay in forward_step.F)
547    o update coupling interface to work with new staggerTimeStep
548    o change MDSIO ptracers_pickup.
549    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
550    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
551    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
552    
553    checkpoint54c_post
554    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
555      this affects (truncation error) output.txt of test-exp:
556       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
557    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
558    o change Qnet to always be the net heat flux, (+upward).
559      affects (truncation error) output of natl_box exp.: updated
560    o define the max number of passive tracers in PTRACERS_SIZE.h
561    o start to test mnc routinely in exp0
562    o add sea-ice loading (sIceLoad) as a new forcing field.
563    
564    checkpoint54b_post
565    o add testreport "-j JOBS" option for parallel builds (tested and pretty
566       impressive on Altix and Opteron systems)
567    o diagnostics can now write NetCDF files through the mnc package
568    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
569    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
570    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
571      affects (truncation error) output of lab_sea & natl_box exp.: updated
572    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
573    
574    checkpoint54a_post
575    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
576    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
577    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
578    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
579      + internal_wave (shift in writing cg2d_ini_res)
580    checkpoint54a_pre
581    
582    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
583      - modified verification/lab_sea and natl_box_adjoint accordingly
584    
585    checkpoint54
586    checkpoint53g_post
587    o prepare splitting of thermodynamics: store convect.counter in common block
588    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
589      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
590    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
591    o new parameter "nShapS": allow to treat differently S from T (nShapT)
592    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
593    o restore adjointability
594    
595    checkpoint53f_post
596    o modifications that affect AIM experiment results (update output.txt):
597      - no advection of S at top interface Nr (pkg/generic_advdiff)
598      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
599    o AIM pkg:
600      - include stability function into surf.Flux derivative relative to Tsurf
601      - calculate clear-sky radiation & surface temp. change (for diagnostics)
602    
603    checkpoint53e_post
604    o merged cylindrical coord configuration
605    o added rotating_tank experiment
606    checkpoint53e_pre
607    
608    checkpoint53d_post
609    o faulks upgraded: re-generate output.txt that have changed:
610       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
611    o Added Bryan and Lewis, 1979, vertical diffusivity profile
612    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
613    o added Sadourny discretization of Coriolis
614      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
615      - re-enabled use of omega3 (useAbsVorticity)
616    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
617      vector-invariant equations
618      - note: does *NOT* yet use same variable visc. for no-slip BC's.
619    o recoded the lateral boundary conditions for non-hydrostatic w, this time
620      hopefully without new bugs
621      - still to do: biharmonic friction for non-hydrostatic w
622    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
623    o regenerated output for global_ocean_ebm (using -ieee)
624    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
625      of mom_common/
626      - simple re-arrangement of instructions within computing loop
627    checkpoint53d_pre
628    
629    checkpoint53c_post
630    o new version of coupler for AIM+thSIce and Ocean models
631     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
632     - land: change Evaporation of snow
633     - aim with thSIce: fix bug in snow-precip.
634    o changes to calc_gw.F
635     - bug fix for w^2 term near the bottom boundary
636     - (hopefully) improve the lateral slip boundary condtions for use with
637        partial/looped cells
638      - because the bug fix changes two verification experiments anyway (exp5
639        and plume on slope), change the lateral boundary condition from half slip
640        to the value of no_slip_sides
641    o ebm package wasnt quite up to the parallel task. Fixed that.
642    o Adjoint of EBM package + verification
643      * TLM OK
644      * ADM not sufficient accuracy yet (needs further testing)
645    
646    checkpoint53b_post
647    o Commiting new energy balance model to repository
648      * package is pkg/ebm
649      * verif. is verification/global_ocean_ebm
650      * references are in ebm_driver.F
651    C      * X. Wang, P. Stone and J. Marotzke, 1999:
652    C        Global thermohaline circulation. Part I:
653    C        Sensitivity to atmospheric moisture transport.
654    C        J. Climate 12(1), 71-82
655    C      * X. Wang, P. Stone and J. Marotzke, 1999:
656    C        Global thermohaline circulation. Part II:
657    C        Sensitivity with interactive transport.
658    C        J. Climate 12(1), 83-91
659    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
660    C        Destabilization of the thermohaline circulation
661    C        by atmospheric eddy transports.
662    C        J. Climate 7(12), 1870-1882
663    o Will need long integration testing.
664    checkpoint53b_pre
665    
666    o created pkg/mom_common in preparation for variable viscosity code
667    o renamed and split ini_mnc_io
668    o pkg/land: only liquid water can diffuse or run-off
669    o AIM using land: soil wetness availability account for snow
670    o added printMapIncludesZeros to EEPARMS namelist
671    
672    checkpoint53a_post
673    o restore TAMC compatiility for exf_constants.h
674      (no usage of _d in .h)
675    o Additional storing in KPP in an attempt to fix
676      TAMC problem with adjoint of KPP code.
677      (no success...)
678      Identical code works fine with TAF.
679    o Fixed verification/natl_box_adjoint experiments.
680      Initial conditions for Experiments 4 and 5 are now
681      set to "SEAICE_initialHEFF=0", which is more reasonable,
682      and hence gives results closer to that of Experiment 2.
683      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
684    
685    checkpoint53
686    o stable checkpoint with up to date adjoint
687      TLM tests only run for 1st grdchk at the moment. Its unclear if
688      this is a code problem or a problem with resetting code for g_
689      variables that is being autogenerated wrong.
690      Otherwise:
691       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
692       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
693         are both still in chaos following their security messes.
694    
695    checkpoint52n_post
696    o various build (mostly genmake2) changes including:
697      - ability to build/run more easily within Cygwin and MacOS X
698      - more complicated Makefiles with a stronger dependence on Gnu Make
699    o pkg/seaice modifications
700      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
701        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
702        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
703      - changed proxy for geostrophic velocity and updated
704        verification/lab_sea/results/* accordingly
705      - removed ADI dynamic solver from pkg/seaice
706      - replaced all occurrences of 1/CSTICE or 1/CSUICE
707        they caused a segmentation fault under certain circumstances
708      - removed unused field WATR
709    o bug fix in exf-package:
710      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
711         now reflect that.
712    o small fixes in the cal-package:
713      - set reference date to first of January for the 'model'-calendar
714      - failing of cal_CheckDate in cal_FullDate now actually results in a
715        warning
716    o small modifications in exf-package to increase flexibility:
717      - change climtempfreeze from a constant to a runtime parameter that
718        is specified in data.exf_clim (default = -1.9)
719      - introduce runtime parameter windstressmax (default = 2.0) that is
720        specified in data.exf
721    o fix in pkg/thsice:
722      - update Evap (Tsf changes) to be consistent with Latent heat flux
723      - maintain snow precipitation unchanged (even if Tsf >=0).
724     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
725    
726    checkpoint52m_post
727    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
728      this does not change any of the results, because myIter=0 in swfrac always
729      lead to jwtype=2 (the default anyway), but the call makes little sense
730      as a default
731    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
732    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
733      atmospheric model (AIM) to use it ; add a "slab ocean" component.
734    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
735    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
736    o extending useSingleCpuIO option to work with new exch2 I/O format
737      - old-style, missing-tile I/O is still accessible by defining CPP
738        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
739    o monitor package can write to NetCDF files and/or STDOUT
740    o fix re-definition bug in MNC_GRID_INIT_ALL()
741    o doc/api_reference added
742      - a framework for building an API Reference Manual using all
743        the "protex" comments embedded in the code
744      - see pkg/generic_advdiff, pkg/mnc for examples
745    o MNC:
746      - make myThid the last argument for all subroutines
747      - new default for the grid files: NO halos
748      - add useMNC and other run-time flags
749      - separate per-file-group handling of the unlimited dimension
750      - early initialization of MNC w/ flags read at the eeboot stage
751        and lookup tables set in initialize_fixed
752      - write all MNC output to a freshly-created directory
753    o thermodynamics sea-ice (thsice) is now tested with testreport.
754    o test exp. advect_cs: use the standard cs32 grid ; update output.
755    o Added functionality to grdchk:
756      pick global i,j,k position (or nearest wet) where to perform check.
757    
758    checkpoint52l_post
759    o new land formulation:
760      a) use ground enthalpy as prognostic variable to ensure exact
761         energy conservation.
762      b) account for water temperature and for latent heat of freezing
763         in all processes (rain, run-off, ground storage)
764      c) compute surface and ground temperature implicitly.
765    o aim_v23 modification for new land model:
766      a) Treat separately land / ocean / sea-ice surface fluxes

785    o fixed bug introduced in pkg/monitor
786    o accuracy ctrlprec = 32 insuffient for gradient checks using
787      averaged fields (I/O via cost_averages)
788      -> use ctrl.h in active_file*.F to control I/O precision.
789    o paramter list of CALL ADTHE_MAIN_LOOP

796    o fix nchklev in tamc.h for global_ocean...
797    o Bringing flow and store directives up-to-date
798    o Really weird thing!
799      call do_the_model_io from the_main_loop with parameters
800      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
801      TAF places a faulty re-call of initialise_varia
802      after cost_final call which should not be there!
803    checkpoint52j_pre
804    
805    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
806      error messages

834    o added useSingleCPUIO flag to monitor.F and mon_out.F
835    o added temporary hack for sea-ice dynamics on the cube:
836      metric terms are ignored and it is assumed that
837      there is no sea-ice on cube faces 1, 2, 4, and 5.
838    
839    checkpoint52f_post
840    o added exch2 cube routines to pkg/exch2

844    
845    checkpoint52e_post
846    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
847      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
848    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
849      to work with implicit vertical advection and AB ;
850    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
851    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
852     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
853    checkpoint52e_pre
854    
855    o fix bug in impldiff when Nr=1 or Nr=2.
856    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
857    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
858    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2

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

914     - modify fluxes but do not change theta directly;
915     - light cleaning of bulk_force pkg (still needed with thsice).
916     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
917       + output_thsice.txt to test thsice & bulk_force pkgs.
918    o put back grid & coriolis monitor output.
919    checkpoint52b_pre
920    
921    o call "do_the_model_io" at the beginning (=> dump initial state)
922    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
923    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
924      (need info on NUMBER_OF_PTRACERS)
925    o missing PTRACERS headers in some routines
926    o default tamc.h in pkg/autodiff supposed to crash
927      to ensure proper customization
928    
929    checkpoint52a_post
930    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
931      - moved surfaceTendencyTice from pkg/seaice to main code
932      - subroutine FREEZE_SURFACE now limits only surface temperature
933        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
934        => new output.txt for global_ocean.cs32x15 & global_with_exf
935      - keep the old version of FREEZE for backward compatibility;
936        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

945    o some bug fixes for #undef REAL4_IS_SLOW
946    
947    checkpoint52 = ecco_c52_e35
948    o after testing adjoints of checkpoint51u_post
949    
950    checkpoint51u_post
951    o this is the post-merge tag of the ecco-branch
952      (needs another clean checkout and re-testing)
953    o various natl_box_adjoint configs and results
954      but no input fields
955    o obcs adjoint not yet merged!
956    o adding ECCO global 1x1 and 2x2 degree configs
957    o updated/extended some store directives for seaice
958    o pkg/ecco now containes ecco-specific part of cost function

962      (new namelist ecco_cost_nml)
963    o in ctrl/ cleaned some cross-dependencies and updated CPP options
964    
965    checkpoint51t_post
966    o this is the pre-merge tag of the ecco-branch
967

970    o pkg/grdchk
971      - renamed 'ph-grd 3' to 'grad-res'
972      - merged from ecco-branch
973        (remaining bug fixes for obcs gradient checks)
974      - additional high-precision output for testreport
975        (grep for 'precision_grdchk_result')
976    
977    checkpoint51r_post
978    o cleaned up or removed CPP_OPTIONS.h files
979    o updated results for some of the tests to reflect the new
980      optfiles (-ieee: -O0 instead of -O3)
981    
982    checkpoint51q_post
983    o cd_code:
984      - moved cd_scheme.F -> cd_code_scheme.F

996    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
997    
998    checkpoint51p_post
999    o create initial cd_code package
1000      - WARNING: the initialization of fields within packages
1001        is broken because INI_FIELDS (where READ_CHECKPOINT is
1002        called) is called *before* PACKAGES_INIT_VARIABLES.
1003        This seems to be backwards since
1004        1) its important to initially zero the entire field including
1005           the "halo" region
1006        2) zeroing needs to be done *before* reading pickup info
1007           and the pickup call might or might not happen in any
1008           particular run
1009      - this needs an overhaul for R2
1010    o cleanup verification/*/code/GMREDI_OPTIONS.h

1021    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
1022    o bug fix in find_alpha.F for MDJWF:
1023      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
1024        change rho -> rho-rhoConst
1025      - replace call find_rho to find_rhonum

1044      - moved surfaceTendencyTice from pkg/seaice to main code
1045      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1046      - subroutine FREEZE now limits only surface temperature
1047        (this means new output.txt for global_ocean.90x40x15,
1048         global_ocean.cs32x15, and global_with_exf)
1049    o added surface flux output variables to TIMEAVE_STATVARS

1077    
1078    checkpoint51k_post
1079    o change default to: useNHMTerms=.FALSE.

1171    
1172    checkpoint51c_post
1173    o introducing integer flag debugLevel
1174      - debLevZero: suppress all output
1175      - debLevA: standard
1176      - debLevB: equivalent to current debugMode=.TRUE.
1177    o introducing pathname variable mdsioLocalDir for mdsio
1178      that can be specified at runtime
1179      (relevant for cluster I/O to local disk)
1180    `
1181    >>>checkpoint51b_post
1182    adjoint of ptracers
1183    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1184    o extended state in checkpoint_lev?, etc.
1185    o alternative ctrl/cost with tr1 or ptracer
1186    o new comlev1_bibj_ptracers
1187    o new ptracers.flow
1188    o made ptracers_forcing same as external_forcing_s
1189    o added verification for adjoint with ptracers
1190      - adm. grdchk fail so far
1191      - tlm. grdchk OK
1192      - checked tapelev/comlev recomputations: OK
1193    <<<checkpoint51b_pre
1194    
1195    checkpoint51a_post
1196    o added code for biogeochemistry package
1197      - new pkgs: dic, gchem
1198      - new subroutine in ptracers
1199    o modify code for biogeo packages
1200      - in model/src and pkg/ptracers
1201    
1202    checkpoint51
1203    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1204      - autodiff, ctrl, exf, grdchk, seaice
1205      kept separate packages
1206      - cost, ecco, obcs
1207    o updating verification/internal_wave, verification/lab_sea
1208      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1209    
1210    checkpoint50i_post
1211    o Preparing next differentiable checkpoint and sync
1212      of MAIN vs. ecco-branch
1213      - 1st step: this one is differentiable
1214      - 2nd step: next(! not this) checkpoint will have updated packages
1215                  from ecco-branch)
1216    
1217    checkpoint50h_post
1218    o new package "land": provide surface BC for AIM.
1219    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1220    o AIM: use true log-P extrapolation for near surface temp (= as in
1221        F.Molteni paper) ; update aim.5l_cs output.
1222    o New variable in PARM03 for more flexible pickups
1223    o somewhat cleaned package initialisation sequence for
1224      ctrl/ cost/ ecco/ in packages_... routines
1225    
1226    checkpoint50g_post
1227    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1228      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1229      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1230        made the default because of faster convergence than ADI
1231    
1232    checkpoint50f_post
1233    o exf totally restructured
1234      - replaced all exf_set_ routines by one generic exf_set_gen.F
1235        and made sure it's still differentiable
1236      - split exf_getffields.F into new exf_bulkformulae.F
1237      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1238      - updated adjoint/makefile and relevant verif. accordingly
1239    
1240    checkpoint50f_pre

1242          + change Evap over land. (update aim.5l_cs output)
1243     o added missing .cvsignores and made uniform across expts
1244     o changed configuration of tidal_basin_2d expt
1245     o added pkg/debug functions for tracing code in fatal crashes

1247     o new fn in pkg/monitor to stop model if solution grows too big
1248     o removed lots of single quotes from comments
1249    
1250    checkpoint50e_post
1251    o make KPP work with PTRACERS
1252     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1253       nearly a copy of kpp_transport_s
1254     - there is no analogue to SurfaceTendencyS, so I have to use
1255       gPtr(of the surface layer) instead
1256    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1257    checkpoint50e_pre
1258    
1259    checkpoint50d_post
1260    o change kpp output from multiple-record state files to single-record state
1261      files analogous to write_state.F
1262    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1263      analogous to the cg2d-related output.
1264    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1265      so that writing to internal file fn (with length 512) fails.
1266    checkpoint50d_pre
1267    
1268    checkpoint50c_post
1269    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1270    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1271    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1272    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1273    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1274    
1275    checkpoint50c_pre
1276    Merging from release1_p13:
1277    o bug fix for pkg/seaice dynamic solver
1278    o Added SEAICE_initialHEFF to pkg/seaice
1279    
1280    checkpoint50b_post
1281    o store u*,v* in gU,V instead of in guNm1,gvNm1
1282    o in order to put the momForcing out of the Adams-Bashforth:
1283      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1284      to timestep.F
1285    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1286    o re-generate output for highly sensitive test-exp:
1287       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1288    
1289    checkpoint50b_pre
1290    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1291    o corrected CPP option mismatch in exf_Bulk... functions for case
1292      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1293    
1294    checkpoint50a_post
1295    o Bug fix for merging between c50 and KPP.
1296      ikey was passed from thermodynamics to kpp_calc via
1297      common block rather than being recomputed in kpp_calc,
1298      in contradiction with new key itdkey.
1299      New key ikppkey created, and tamc.h headers updated.
1300    
1301    checkpoint50
1302    - 2nd step of merge with ecco-branch:
1303      merge changes in ecco-branch back into main trunk
1304    - bug fix in find_alpha
1305    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1306    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1307    - merged some sliced AD support routines
1308    
1309    checkpoint49
1310    merged from ecco-branch:
1311    o exf:
1312      - Enable initialisation of forcing fields to constant
1313        (runtime) values.
1314      - in exf_getffields.F
1315        Reduce i-/j-loop to interior domain, discarding overlaps.
1316        That also fixes wrong TAF-key computations for key_1, key_2
1317        with bulf formulae.
1318      - exf_init.F modify #ifdef for exf_init_evap
1319      - exf_getffieldrec.F, ctrl_getrec.F
1320        The following INT-usages are not safe:
1321          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1322          fldcount = int(fldsecs/fldperiod) + 1
1323        and were modified.
1324    o autodiff: checkpoint_lev...
1325      - updated storing for bulk formulae (some arrays were missing)
1326      - added state for seaice package
1327      - synchronized with main branch
1328    o DIVA:
1329      Modif.s in
1330      - the_main_loop.F
1331      - the_model_main.F
1332      and added cost_final_restore.F cost_final_store.F
1333      o With these changes, it is possible to fully separate
1334        the first forward run to compute the cost function (mdthe_main_loop)
1335        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1336        into separate model executions.
1337        This enables better tuning of DIVA to given queue sizes.
1338      o Loss of cost function value in consecutive DIVA runs is
1339        fixed by storing to 'costfinal' file.
1340      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1341        beginning/end of adjoint integration is accounted for.
1342      The current changes apply to TAF-1.4.26.
1343      TAF has one remaining bug, requiring one manual change
1344      (see MITgcm manual).
1345    o cal: synchronized between MAIN and ecco-branch
1346    
1347    checkpoint48i_post
1348    o Changes to restore differentiability of code w.r.t. previous tag
1349      (mostly adding new routines to make list and replacing
1350      pressure by totPhiHyd).
1351    o Updated and merged grdchk package
1352      - has both ADM and TLM checks
1353      - works for single- and multi-proc.
1354      - output cleaned
1355      - worked successfully for parallel DIVA
1356    o genmake:
1357      - Adding -platform=SP4
1358      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1359    o Modif. for DIVA:
1360      ctrl_unpack should not be called in intermediate DIVA interval.
1361      (similar thing would apply for active files such as
1362      tbar, sbar, psbar, which should not be reinitialised;
1363      only relevant for ecco-branch)
1364    
1365    checkpoint48h_post
1366    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1367    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1368    o Added SEAICE_initialHEFF to pkg/seaice
1369    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1370    
1371    checkpoint48g_post
1372    --- EOS:
1373    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1374      store total Potential in totPhyHyd for diagnostics & EOS.
1375    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1376    --- Pressure/geopotential gradient:
1377    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1378    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1379      ( changes results of global_ocean_pressure )
1380    o NLFS + z-coord.: add eta*Rho' contribution.
1381    o accurate phiHyd when using interface-W at the middle between 2 centers
1382     ( changes results of ideal_2D_oce )
1383    o includes r* 2nd term in potential gradient.
1384    
1385    checkpoint48f_post
1386    Merging from release1_p12:
1387    o Modifications for using pkg/exf with pkg/seaice
1388      - improved description of the various forcing configurations
1389      - added basic radiation bulk formulae to pkg/exf
1390      - units/sign fix for evap computation in exf_getffields.F
1391      - updated verification/global_with_exf/results/output.txt
1392    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1393      (SBO) core products, including oceanic mass, center-of-mass,
1394      angular, and bottom pressure (see pkg/sbo/README.sbo).
1395    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1396      to avoid negative values in shallow regions.
1397      - updated verification/natl_box/results/output.txt
1398      - updated verification/lab_sea/results/output.txt
1399    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1400    o Added useSingleCpuIO option (see PARAMS.h).
1401    o Updated useSingleCpuIO option in mdsio_writefield.F to
1402      work with multi-field files, e.g., for single-file pickup.
1403    o pkg/seaice:
1404      - bug fix in growth.F: QNET for no shortwave case
1405      - added HeffFile for specifying initial sea-ice thickness
1406      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1407    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1408      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1409    o pkg/seaice:
1410      - adjoint-friendly modifications
1411      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1412    
1413    checkpoint48e_post
1414    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1415    o dynamics: change definition of computational domain & adapt mom_fluxform
1416      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1417    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1418        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1419        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1420        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1421        inverted_barometer solid-body.cs-32x32x1
1422      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1423    
1424    checkpoint48d_post
1425    o in preparation for r*:
1426     a) use pre-computed gradient of hydrostatic potential:
1427        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1428     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1429        => affects results of glob_oce_pressure (different truncation error)  
1430      update output.txt of ideal_2D_oce & global_ocean_pressure
1431    
1432    checkpoint48d_pre
1433    o in preparation for r*:
1434      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1435      pass the 2 comp. of the grad. as arguments to momentum S/R.
1436      but for the moment, only used if it does not change the results.
1437    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1438    
1439    checkpoint48c_post
1440    Modifications in treatment of initial flux forcing controls
1441    to avoid extra storing of flux fields.
1442    
1443    checkpoint48c_pre
1444    o Added tidal_basin_2d experiment (currently 1D!)
1445    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1446    
1447    checkpoint48b_post
1448    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1449     (modification to pressure gradient not yet implemented)
1450    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1451      (for U & V) that are used for vertical advection of momentum.
1452    
1453    checkpoint48a_post
1454    o In preparation for r*, use temp. array to compute vertical transport
1455       in flux-form momentum pkg. => change results of few test-exp.
1456      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1457                        lab_sea, natl_box & plume_on_slope
1458    
1459    checkpoint48
1460    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1461    
1462    checkpoint47j_post
1463    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1464    o moved adexch from forward_step to addummy_in_stepping
1465    o added exch in ctrl_map_...
1466    o aveFreq.=0. at end of cost_final to avoid overwrite in
1467      reverse checkpointing loop
1468    o Yet more changes in gmredi:
1469      * adgmredi_calc_tensor
1470        avoiding all recomputation of gmredi_slope_limit
1471      * adgmredi_x/y/rtransport
1472        added flag for excessive storing to avoid recomp. of
1473        u/v/rtans, dTdx/y/z
1474        -> this is not really necessary and very memory-consuming
1475      * adgmredi_slope_psi:
1476        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1477      * gmredi_slope_limit
1478        re-activated full calculation of taperfct for case 'ac02'
1479    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1480    
1481    checkpoint47i_post
1482    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1483    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1484      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1485    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1486    o gmredi: fix few bugs.
1487    
1488    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1489    This will be a good checkpoint to plug into the ecco-branch.
1490    o few modif.'s to get latest version adjointed
1491      (mainly kick out code in ini_linear_phisurf)
1492    o modif's to run adjoint with exactConserv
1493    o case GM_BOLUS_ADVEC should be cleaned
1494      S/R gmredi_slope_psi should be cleaned
1495    o verification/carbon now has exactConserv=.TRUE.
1496    
1497    checkpoint47g_post
1498    o time-average AIM output: becomes independent from statvars time-average
1499      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1500    o After TAF bug fix:
1501      Tested adjoint of gmredi package.
1502      Tests were done with checkpoint47 rather than with latest
1503      checkpoint47f_post since the latter is broken for the adjoint
1504      verification/carbon/ contains both ADM and TLM gradient checks.
1505    Here they are, before they get changed/lost/stolen.
1506    Mostly modif.'s to fix numerical sensitivities.
1507    Gradient checks OK for
1508    - GM_taper_scheme:
1509      * clipping
1510      * ac02
1511      * linear
1512      * glw91
1513      * dm95
1514      * ldd97
1515    - GMREDI_OPTIONS:
1516      * GM_VISBECK_VARIABLE_K
1517      * GM_NON_UNITY_DIAGONAL
1518      * GM_EXTRA_DIAGONAL
1519      * GM_BOLUS_ADVEC
1520    in conjunction with data.gmredi parameters to be checked in
1521    in a few minutes under verification/carbon/code/
1522    
1523    checkpoint47f_post
1524    Merging from release1_p10:
1525    o modifications for using pkg/exf with pkg/seaice
1526      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1527        and SEAICE_EXTERNAL_FLUXES
1528      - pkg/exf CPP options EXF_READ_EVAP and
1529        EXF_NO_BULK_COMPUTATIONS
1530      - usage examples are Experiments 8 and 9 in
1531        verification/lab_sea/README
1532      - verification/lab_sea default experiment now uses
1533        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1534    
1535    checkpoint47e_post
1536    o created a tag prior to creating a branch
1537    
1538    checkpoint47d_post
1539    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1540      at the bottom boundary had an erroneous half slip boundary condition
1541    o added bottom drag and no slip boundary condition capabilities to
1542      oceanic pressure coordinates code
1543    o added new verification experiment global_ocean_pressure, this experiment is
1544      also described in the tutorial section of the manual
1545    checkpoint47d_pre
1546    
1547    checkpoint47c_post
1548    o Added a verification experiment for a global cubed-sphere ocean run
1549      -  verification/global_ocean.cubed32x32x30
1550      -  uses pkg/therm_seaice and pkg/bulk_forcing
1551    
1552    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1553    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1554      when using P-coordinate; only implemented for atmospheric config.
1555    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1556      NOTES: requires option NONLIN_FRSURF to be "#define".
1557    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1558    
1559    checkpoint47b_post
1560    Merging from release1_p9:
1561    o pkg/seaice
1562      - removed GOTO's and added taf directives
1563      - double precision constants to reduce the g77 (Linux)
1564        to F77 (SGI) differences reported in release1_p8
1565    o tools/genmake
1566      - added SGI options
1567    o verification/testscript
1568      - updated to that of checkpoint47a_post
1569    o verification/global_ocean.90x40x15/input/eedata
1570      - modified for SGI f77 compatibility
1571    o verification/lab_sea
1572      - added description of sea-ice model
1573      - added missing matlab routines
1574      - added test of thermodynamics parallelization
1575    
1576    checkpoint47a_post
1577    o new pkg: aim_v23
1578     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1579       for now, keep the same surface forcing as before.
1580     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1581     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1582     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1583    o add diagnostic of surface correction term in monitor output
1584    
1585    o bulk_force and therm_seaice
1586    - Two packages:  bulk_force (Bulk forcing)
1587      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1588    - Earlier integration from Stephaine Dutkiewicz
1589      and Patrick Heimbach.
1590    - Two ifdef statements for compile time,
1591       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1592    
1593    checkpoint47
1594    differentiable version of checkpoint46n_post
1595    o bug fix in quasihydrostaticterms
1596    o * "clean" adjoint code (in terms of extensive recomputations)
1597        can now be obtained for all GMREDI options (i.e. for
1598        - GM_VISBECK_VARIABLE_K
1599        - GM_NON_UNITY_DIAGONAL
1600        - GM_EXTRA_DIAGONAL
1601        - GM_BOLUS_ADVEC )
1602      * However, wrong gradient check problem remains unsolved.
1603      * New CPP options have been introduced for different
1604        tapering schemes
1605    o external_fields_load now part of differentiation list
1606    o pressure needs multiple storing;
1607      would be nice to have store_pressure at beginning or
1608      end of forward_step, e.g. by having phiHyd global (5-dim.)
1609      (NB: pressure is needed for certain cases in find_rho,
1610      which is also invoked through convective_adjustment).
1611    o recomputations in find_rho for cases
1612     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1613    o #define ATMOSPHERIC_LOADING should be differentiable
1614    o ini_forcing shifted to begining of initialise_varia
1615    o Incorporating QNVS line search routines into MITgcm
1616      (this is separate code, and therefore not under pkg)
1617      lsopt/, optim/
1618    o Updated verification/carbon/
1619      - #define GM_VISBECK_VARIABLE_K
1620      - GM_taper_scheme    = 'ldd97'    
1621    
1622    checkpoint46n_post
1623    Merging from release1_p8:
1624    o verification/natl_box:
1625      updating new external_fields_load routine
1626    o New package: pkg/seaice
1627      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1628      The sea-ice code is based on Hibler (1979-1980).
1629      Two sea-ice dynamic solvers, ADI and LSR, are included.
1630      In addition to computing prognostic sea-ice variables and diagnosing
1631      the forcing/external data fields that drive the ocean model,
1632      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1633      The implied surface heat flux is then stored in variable
1634      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1635      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1636      non-local transport term.  Because this call precedes model
1637      thermodynamics, temperature under sea-ice may not be "exactly" at
1638      the freezing point by the time theta is dumped or time-averaged.
1639      N.B.: fairly large differences in accuracy occur across
1640            different platforms/compilers; comparison between
1641            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1642            generated output gives:
1643       T           S           U           V
1644      C D M    c        m  s        m  s        m  s        m  s

1648    
1649      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1650    o GAD:
1651      - generated new common blocks to account for call of
1652        same gad routines with differing traceridentities
1653        (needed to modify tracerIdentity indices in GAD.h)
1654      - generated separate common blocks for case useCubedSphereExchange
1655        (Department of Futurology)
1656      - parameter lists to gmredi_?transport: added tracerIdentity
1657      - added new key indices to tamc.h
1658    o external_fields_load:
1659      - added this routine to TAF list
1660      - needed to make some common blocks global and additional storing
1661        along the same lines as exf package (checkpoint_lev?_directives.h)
1662    o exf:
1663      updated external forcing package
1664      - bug fixes carried over from ecco-branch
1665        (missing OBCS_OPTIONS.h in two routines)
1666      - enable easy to use "no forcing".
1667      - added exf I/O for atmospheric loading
1668      - added exf I/O for runoff data
1669      - transfered scaling between exf <-> MITgcm to exf namelist
1670    o Adding new verification experiment global_with_exf.
1671      This verification experiment is almost identical to the
1672      global_ocean.90x40x15 experiment, except that it uses
1673      the exf (and cal) package instead of the
1674      external_fields_load routine (cf README file).
1675    
1676    checkpoint46m_post
1677    o modified testscript to return -- when there are no lines of "%MON" output
1678    o added new flag "quasiHydrostatic" for QH mode
1679      and new routine quasihydrostaticterms()
1680    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1681      New routine: mom_u_coriolis_nh()
1682    o fixed sign of non-hydrostatic metric terms in u and v equations.
1683      Depend on correct sign of gravitySign.
1684    o added work.pc* to .cvsignore in aim directories using ifc
1685    o introduced flag for controllin non-hydrostatic metric terms
1686    o removed gravitySign from PARM04
1687    o switched to g77/ifc from pgf77 in aim experiments
1688    
1689    checkpoint46l_post
1690    o made convective adjustment work with pressure coordinates:
1691     - changed the direction of k-loop in convective_adjustment.F for the
1692       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1693     - adjusted the reference pressure k-index in convective_adjustment.F
1694     - adjusted the convection condition in convect.F (in analogy to
1695       calc_ivdc.F)
1696     - convective_adjustment no longer computes anything on the halos
1697     - removed the warnings about negative salinity from find_rho.F and
1698       find_alpha.F; instead the new routine look_for_neg_salinity, called
1699       at the beginning of find_rho, find_alpha, and find_beta, does a
1700       check of the entire slice, if CPP-option
1701       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1702    checkpoint46l_pre
1703    
1704    checkpoint46k_post
1705    o fixed the verification/global_ocean.90x40x15 experiment:
1706     - new bathymetry (the world according to A., JMC, and M.)
1707     - new initial fields and forcing fields (*.bin files)
1708     - new POLY3.COEFFS (for the next release one should switch to a full
1709       equation of state: JMD95P or MDJWF)
1710     - fixed several errors and redundancies in the data file
1711     - experiment uses looped cells
1712     - added matlab directory with diagnostic scripts for plotting of output
1713    
1714    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1715     - read AIM physics parameters from a file (data.aimphys)
1716     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1717    
1718    checkpoint46j_post
1719    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1720    o move wVel computation at the end of the time step, in S/R integr_continuity
1721    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1722    o update timeave pkg for wVel diagnostic.
1723    checkpoint46j_pre
1724    
1725    checkpoint46i_post
1726    o Clean up AIM package (and keep the results unchanged):
1727      include CPP_OPTION and use IMPLICT NONE in all routines ;
1728      declare all the variables _RL ; use _d 0 for all numerical constants.
1729      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1730    
1731    checkpoint46h_post
1732    o cleaned up the use of rhoNil and rhoConst.
1733      - rhoNil should only appear in the LINEAR equation of state, everywhere
1734        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1735        and the dynamical equations are all divided by rhoConst
1736    o introduced new parameter rhoConstFresh, a reference density of fresh
1737      water, to remove the fresh water flux's dependence on rhoNil. The default
1738      value is 999.8 kg/m^3
1739    o cleanup up external_forcing.F and external_forcing_surf.F
1740      - can now be used by both OCEANIC and OCEANICP
1741    checkpoint46h_pre
1742    
1743     Added code to convert surface volume flux (fresh water) into
1744     a mass flux when using P coordinates in the ocean (OCEANICP).
1745     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1746    
1747    checkpoint46g_post
1748    o Include a new diagnostic variable phiHydLow for the ocean model
1749      - in z-coordinates, it is the bottom pressure anomaly
1750      - in p-coordinates, it is the sea surface elevation
1751      - in both cases, these variable have global drift, reflecting the mass
1752        drift in z-coordinates and the volume drift in p-coordinates
1753      - included time averaging for phiHydLow, be aware of the drift!
1754    o depth-dependent computation of Bo_surf for pressure coordinates
1755      in the ocean (buoyancyRelation='OCEANICP')
1756      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1757        Theta, Salinity, and Pressure in the parameter list. This routine is
1758        presently contained in find_rho.F. This routine does not give the
1759        correct density for 'POLY3', which would be a z-dependent reference
1760        density.
1761    o cleaned up find_rho
1762      - removed obsolete 'eqn' from the parameter list.
1763    o added two new verification experiments: gop and goz
1764      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1765    checkpoint46g_pre
1766    
1767    checkpoint46f_post
1768    o Enable tangent linear (forward mode) gradient checks:
1769      - extended active file handling to g_... files
1770      - added TANGENT_SIMULATION to theSimulationMode
1771      - extended grdchk package accordingly
1772    o added tangent linear setup in verification/carbon/code_ftl
1773    o added adjoint setup in verification/front_relax/code_ad
1774    
1775    checkpoint46e_post
1776    o Added new equation of state -> MDJWF
1777      - EOS of McDougall et al., 2002, JAOT, submitted
1778      - caveat: the equation of state is only valid for a smaller (more
1779        realistic?) range of values than JMD95P/Z and UNESCO
1780      - added masks to the calculation of pressure in store_pressure
1781      - added more check values for density in check_eos (ini_eos.F), some of
1782        the old check values are out of the range of the MDJWF-eos, so don't
1783        expect perfect matches for those
1784    checkpoint46e_pre
1785    
1786    checkpoint46d_post
1787    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1788      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1789      case of pressure coordinates. eosType='JMD95Z' in
1790      combination with buoyancyRelation='OCEANICP' now causes an error.
1791    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1792      in find_alpha/beta.
1793    checkpoint46d_pre
1794    
1795    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1796      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1797    
1798    checkpoint46c_post
1799    o Changes necessary for ocean in p-coordinates
1800     -  Added new buoyancy relation = 'OCEANICP'
1801     -  Added new parameters = gravitySign (this used to be contained inside
1802        the factor dRdZ which I added when we first switched to R coordinates).
1803     X GM/Redi is not compatible (yet)
1804     X bottom drag and no-slip need to be debugged.
1805    checkpoint46c_pre
1806    
1807    checkpoint46b_post
1808    o Added new equation of state -> JMD95Z and JMD95P
1809      - EOS of Jackett and McDougall, 1995, JAOT
1810      - moved all EOS parameters into EOS.h
1811      - new routines ini_eos.F, store_pressure.F
1812    o Added UNESCO EOS, but not recommended because it requires
1813      in-situ temperature (see JMD95)
1814    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1815      unesco.f to be used with POLY3
1816    checkpoint46b_pre
1817    
1818    checkpoint46a_post
1819    o Added (atmospheric) pressure loading
1820      - new field in FFIELDS.h, etc...
1821      - new cpp flag ATMOSPHERIC_LOADING
1822    o Changed hFacC to _hFacC in calc_phi_hyd.F
1823    o Added SHORTWAVE_HEATING to some files for consistency
1824    checkpoint46a_pre
1825    
1826    checkpoint46
1827    further merges from release1_p5
1828    o new ctrl package
1829      - adopted from ECCO environment to enable optimization
1830      - added Eliassen Palm fluxes to controls
1831    o added Eliassen Palm flux controls to gradient check package
1832    o cost package
1833      - Compatible with new ctrl package
1834      - added Eliassen Palm cost hooks
1835      - modif's of existing cost functions
1836    o Adjoint-related bug fixes in kpp:
1837      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1838      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1839    o autodiff package
1840      - flow directives:
1841        + new for S/R do_the_model_io
1842        + enhanced for S/R checkpoint
1843        + new gmredi.flow
1844      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1845        disable adcommon.h/g_common.h by default.
1846      - fixed problem for adjoint of global_max
1847    o modified verification/carbon/
1848    o New setup for adjoint of global_ocean
1849    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1850    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1851    o incorporated hooks for sponge layer code (external_forcing.F)
1852    
1853    checkpoint45d_post
1854    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1855    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1856      (affects plume_on_slope "cg2d" output)
1857    o add new parameter deltaTfreesurf for free-surface time stepping
1858    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1859    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1860    o change phiMin in exp1 (to agree with documentation)
1861    o add new flags:
1862     - T,S forcing inside/outside Adams-Bashforth
1863     - turn off temp,salt advection and/or forcing
1864     - for each tracer, define internal flag for multiDimAdvection & A-B
1865    o monitor: change definition of KE to check conservation of Energy
1866    
1867    checkpoint45c_post
1868    o Removed f90 comments ("!")
1869    o Modified initialisations to enable exf package for MITgcm
1870      (without invoking ECCO_PACKAGE).
1871    o modifications to gradient check package (Martin Losch)
1872      - enable centered differences
1873      - modified format of standard output
1874    
1875    checkpoint45b_post
1876    o cleaned exchange calls in cg2d
1877    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1878    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1879      to configure barotropic setup (Martin Losch)
1880    o moved some initialisations within bi,bj loop in dynamics
1881      (TAF flow dependency)
1882    o in initialise_varia, moved call packages_init_variables
1883      before convective_adjustment_init
1884      (corresponding adjustment of TAF tape initialisation).
1885    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1886    
1887    checkpoint45a_post
1888    o compute Rho over the whole domain (extend iMin,jMin indices)
1889    o specific exchange for X-slice domain (case Ny=1)
1890    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1891    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1892    
1893    checkpoint44h_post = checkpoint45
1894    o Fix to restore differentiability:
1895      place at which packages_init_variables is called in
1896      initialise_varia is crucial for reverse control flow.
1897    o modifications in GMRedi to enable stable adjoint
1898      (corresponding modif's in thermodynamics, dynamics)
1899    o added missing hook for sponge layer code in external_forcing
1900    o modified test cost functions
1901    o storing in gad_advection (plus removal of write(0,*)!
1902    o missing headers TR1.h added in convective_adjustment routines
1903    o errorMessageUnit set non-equal zero in eeboot
1904      (conflict on some platforms, e.g. IBM SP3)
1905    o modified carbon verif.
1906    
1907    checkpoint44h_pre
1908    o vertical grid option: allow to put the Interface at the middle between
1909      2 cell-centers ; replace delZ in pkg/kpp by drF.
1910    o GM Advective form: Tracers are advected using the residual transport (=
1911      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1912    
1913    checkpoint44g_post
1914    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1915      results) ; ifdef missing in thermodynamics.F
1916    
1917    checkpoint44f_pre,checkpoint44f_post
1918    o added PTRACERS package
1919      This allows an arbitrary number of passive tracers to be integrated
1920      forward simultaneously with the dynamicaly model.
1921      + Implemented so far:
1922        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1923        - I/O and checkpointing
1924        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1925      + Not implemented so far:
1926        - KPP
1927        - OBCS
1928      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1929        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1930        line in data.pkg.
1931      + This package is disabled by default since it increases storage.
1932    
1933    
1934    o testscript: added -cleanup option
1935    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1936                 b) enable to filter 2D fields.
1937    
1938    checkpoint44e_pre,post
1939    o re-wrote convective adjustment to use pre-calculated weights
1940      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1941      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1942      Original calls to convect() still in place.
1943    
1944    chkpt44d_pre,post
1945    o added missing EXCLUDE_MONITOR flags
1946    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1947      (incompatible typ in MIN/MAX expressions caused problems
1948      on IBM SP3)
1949    o in genmake added variable MAKEDEPEND
1950      plus resetting for case SunOS
1951    o added timer_stats.c routine for IBM SP3
1952    o removed variables in dynamics
1953    !!! I forgot to create tag chkpt44d_pre !!!
1954    !!! But chkpt44d_pre = chkpt44c_post    !!!
1955    
1956    o real fresh water flux implemented with non-linear free-surface.
1957

2031                        bi,bj loop
2032      mdsio_writelocal - same as mdsio_writetile except works for local
2033                         arrays
2034      write_local_r? - higher-level wrapper for mdsio_writelocal
2035      Controlled by diagFreq. Defaults to zero (ie. no dumps)
2036      Example given at end of mom_vecinv.F that dumps some local arrays.
2037    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
2038      control flux-form versus vector invariant code.
2039      Switch is runtime flag vectorInvariantMomentum (defaults to false)
2040      or genmake -DISABLE ...
2041    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
2042      (additional storing is now needed for case vecinv;
2043      currently nothing implemented to switch this storing off
2044      in case fluxform is used since no CPP flag available).
2045

2059    o bug fix in gmredi_slope_limit for ldd97
2060    
2061    checkpoint40pre5
2062    o proper initialization of Adams-Bashforth time stepping
2063      + uses forward step for very first step of model (iter=0)
2064    o re-generated *all* output since almost all output is modified by this
2065      change (sorry but we've been putting this one off for about 2 years)
2066      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
2067        *not* regenerated since they are already out of date and I don't
2068        want to create the impression that they are suddenly working.
2069    o removed KAP stuff for DEC's
2070    o modified/added many .cvsignore files in */code and */input
2071    o added new expt "solid-body.cs-32x32x1"
2072      + this uses an alternative form of ini_curvilinear_grid.F which
2073        is not necessarily any better than the current one...
2074    
2075    checkpoint40pre4
2076    o added re-initialisations of utrans,vtrans,rtrans in

2101     o Included following packages:
2102       cal: calendar
2103       exf: external forcing
2104       ecco: essential routines to control use of cal, exf

2106     o disabled some packages by default in genmake
2107    
2108    checkpoint38
2109     o see notes_c37_adj.txt

2114     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
2115    
2116    checkpoint37
2117     o mdsio.F routine split and packaged in pkg/mdsio
2118       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
2119        used unless genmake -disable=mdsio)
2120     o allow a more precise surface-geopotential gradient for the atmosphere
2121       taking into account the change in space of Alpha (=1/rho) at the surface.
2122     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
2123       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
2124     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
2125       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
2126       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
2127     o Time-Average diagnostics defined as a pseudo package "timeave".
2128     o pickup files : old pickup (before c35) did not work with new code (c35
2129       and after) unless activating 2 commented lines in initialise-varia.
2130     o Non-Hydrostatic pickup file Pb fixed.
2131     o bug with Rigid-lid version (since c35) fixed.  
2132    
2133    checkpoint36
2134     o implement Crank-Nickelson barotropic time-stepping
2135     o recover Time-Average diagnostics

2137     o AIM become a standard package ; clean unused CPP_kees
2138    
2139    checkpoint35
2140     o subtantial rewrite of dynamics.f
2141     o allows staggered time-stepping
2142     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
2143     o added bottom drag (linear + quadratic)
2144    
2145    checkpoint34
2146     o Modified exchange routines for correct reverse simulation.
2147     o Added verification output to comply with bug fix in impldiff.F
2148       as of c33 (exp2, natl_box).

2155    
2156    checkpoint33
2157     o Fixed bug in lower BC in impldiff.F
2158     o Fixed confusion about units of forcing arrays in FFIELDS.h
2159       namely Fu,Fv,Qnet,Qsw,EmPmR:
2160       - Removed verification/natl_box/code/external_fields_scale.F
2161         (did not differ from that in model/src)
2162       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
2163         (see FFIELDS.h for description)
2164       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
2165         kpp_calc.F and kpp_transport_t.F
2166       - Removed model/src/external_fields_scale.F and calls to it
2167       - verification/natl_box uses flux data with "atmospheric" sign so
2168         a special version of external_fields_load.F is used to
2169         change the data as it's read in. This way, the arrays
2170         have the right units and signs at all times tha a user could
2171         possibly use them.
2172     o Corrected genmake to delete a temporary file during configuration
2173    
2174    checkpoint32
2175     o Scaling of forcing fields moved from external_forcing.F to
2176       external_fields_scale.F, called directly after loading fields.
2177     o Surface relaxation terms added to surface tendency fields in
2178       extra subroutine.
2179     o impldiff.F changed to avoid storing by TAMC of huge intermediate
2180       fields.

2187       -> new routines packages_...F
2188       -> changes in initialise_fixed.F, initialise_varia.F
2189       -> enables initialisation interface for ECCO package
2190     o Rescaling of external forcing fields immediately after read
2191       (removed from external_forcing.F)
2192       -> new: surface_fields_scale.F
2193       -> affects ini_foorcing.F, external_fields_load.F
2194     o Computation of surface tendencies before tendency updates.
2195       -> new: external_forcing_surf.F
2196     o Change of variable names useGMRedi, useKPP, useECCO
2197     o Further changes in dynamics.F, impldiff.F for TAMC
2198     o Tested for experiments 0, 2, 4.
2199       - not yet tested for GMRedi.
2200       - not yet tested for KPP.
2201    
2202    checkpoint30

2206     o Updates for KPP: calculation of viscosity corrected, new variables
2207       kpp_dumpFreq and kpp_taveFreq
2208     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
2209       and entry for T90 in genmake
2210    
2211    checkpoint29
2212     o packaged KPP and GM/Redi
2213    
2214    checkpoint28
2215     o Corrected initialization of hFacMin for difference vertical coordinates
2216     o Modified calculation of partial cell thickness to more robust algorithm
2217     o config_summary.F: replaced write_1D_... by write_0D_...
2218       read_write.F: added subroutines write_0D_...
2219     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
2220       included some initialisations required for TAMC.
2221     o routine calc_isoslopes: modified sqrt computation to make it
2222       differentiable for zero argument.
2223     o routines dynamics, impldiff:
2224       included store directives and tape key computations required for TAMC.
2225     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
2226    
2227    checkpoint27
2228     o fixed calc_isoslopes() to so that cancellation of terms in tensor
2229       formulation works properly with variable resolution.
2230     o restructured the calling tree between the_model_main() and dynamics()
2231     o split initialise() into initialise_fixed() and initialise_varia()

2233       in new routine ini_psurf()
2234    
2235    checkpoint26
2236     o moved some #ifdef in optional routines to encompass everything
2237       except the argument declarations. This was using up some memory.
2238     o fixed macros like _ADT to work with both versions of Linux cpp
2239     o cleaned up some unused and uninitialized variables
2240       (helps when debugging with strict compile options)
2241     o split up CPP_EEOPTIONS.h into options and macros
2242       (macros are now in eesupp/inc/CPP_EEMACROS.h)
2243     o patch for 2 processor JAM mode
2244    
2245    checkpoint25
2246     o updates for OBCs and NH
2247     o dramatically reduced memory usage
