3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint57f_post
7    o add parameter "baseTime" = model base time = time at iteration zero
8      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
9      account for baseTime shift
10    o move Coriolis arrays from PARAMS.h to GRID.h
11    checkpoint57f_pre
12    
13    o mnc-ifying the seaice package
14    o introduced an alternative length scale calculation for use in the limiting
15      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
16    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
17    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
18      as well as grad(vort3).  Made it compatible with both approximate form
19      for the cubed sphere and full form of these gradients.  Added flag
20      useFullLeith to select between approximate and full form.  
21    o add "d0" in getcon.F to reduce differences between compilers/platforms
22      update output.txt of exp. fizhi-gridalt-hs
23    o change port_rand funtion to allow to set the seed.
24    o fix obscure MNC bug involving conversion between reals and integers
25      - it caused no problems with certain (eg. gcc, ifc) compilers but the
26        new version is now more standards-compliant
27    o adjoint-related modifications
28      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
29      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
30      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
31    
32    checkpoint57e_post
33    o Adding eddy stress controls a la Ferreira et al.
34    checkpoint57e_pre
35    
36    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
37      update output.txt of exp. fizhi-gridalt-hs
38    o add more "Z" dimensions and associated coordinate vars to MNC
39    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
40    o parameter calendarDumps: when set, approximate months (30-31 days) and years
41      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
42      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
43      months and years.  Requires pkg/cal.
44    o diagnostics: add pickup functionality
45      - off by default for backwards compatibility
46      - current version only uses MDSIO -- MNC will be added
47    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
48    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
49    
50    checkpoint57d_post
51    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
52    o modify verification/ideal_2D_oce so that it tests the creation of mnc
53      output from the diagnostics package
54    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
55    o make genmake2 more portable by using ".$FS" instead of ".f" for more
56      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
57    o add coordinate variables to the MNC output from the diagnostics package
58    o change MNC-flags default value: true when useMNC=TRUE
59    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
60      the ability (off by default) to read the grid information using MNC
61    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
62    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
63    o do snap-shot diagnostics at the middle of the time-interval (instead of
64      at the end).
65    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
66      new test for AIM with thSIce + slab-ocean
67    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
68    o move state variable diagnostics to the beginning of the time step ;
69      (note: still needs some work specially for snap-shot diagnostics)
70      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
71    
72    checkpoint57c_post
73    o Change testing option (-ieee) to get closer agreement between g77 & ifort
74    o generate new output.txt files on faulks with g77 & the new -ieee option
75    checkpoint57c_pre
76    
77    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
78      update output.txt of exp. global_ocean.90x40x15
79    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
80      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
81    o add saltFlux(+File) forcing capability with periodicExternalForcing
82    o allow to use pkg diagnostics for GM-Redi & ThSIce output
83    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
84    o improvements for the MNC output from DIAGNOSTICS:
85      - correct handling of the unlimitied dimension
86      - all dims now have associated coordinate variables
87      - variables located at U, V, and Corner ("Z") points are now written
88        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
89        *all* data points are output
90    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
91    o added pkg/seaice/seaice_monitor.F
92    o mdsio_readfield.F can now read files visible only to master MPI process.
93    o pkg/seaice: some test code for ice-modified ocean stress
94    o exf_getffields interpolation defaults to bilinear for all scalar forcing
95      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
96      spurious negative numbers for precipitation and humidity.  Will cause
97      some small numerical differences for integrations using pkg/exf/exf_interp.F.
98    o pkg/ctrl/
99      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
100        May be enabled via doPackDiag
101      *  introduce z-scaling of
102         + gradient (doZscalePack) and
103         + control (doZscaleUnpack)
104    o pkg/mdsio/
105      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
106      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
107    
108    checkpoint57b_post
109    o simplify options in diagnostics_fill arguments (remove weird combinations)
110    o fix MNC coordinate variables so that they now contain per-face index
111      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
112      general, EXCH2 grids are only aligned to a "local" coordinate system
113    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
114    o Implement instantaneous output within pkg diagnostics:
115      setting a negative frequency in data.diagnostics produces
116     "snap-shot" output (as opposed to time-average if freq > 0)
117    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
118      NOTE: change ptracer diagnostics name: use 2 characters to work with
119            more than 9 tracers. Add also diagnostics of advect & diffus flux.
120    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
121      becomes the coordinate variable for the 'T' dimension
122    o add CF-style coordinate variables to MNC
123      - just a first cut:  numbers are meaningless on the cubesphere and
124        missing along the T axis but otherwise it works!
125    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
126    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
127    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
128      this is based directly on what the model compute, so that the content of
129      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
130    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
131    o clean up build options files for SunOS, in particular
132      - remove -traditional from xmakedepend
133      - change -xarch=v9 to -xarch=native for f77
134      - restore use of make (not gmake)
135      - add CC=gcc if using g77
136    o changes per discussion of AM, JMC, & EH3 today:
137      - move redundant "grid" variables out of "state" -- in preparation of
138        creating proper CF-style coordinate variables and in recognition
139        that any/all grid variables can be easily copied (eg. w/NCO) from
140        the grid files into any of the other NetCDF files
141      - *always* output grid variables with MDSIO (this will eventually be
142        changed)
143      - output MNC grid file if useMNC is true
144    o every instance of _END_MASTER() has been found and replaced with
145      _END_MASTER( myThid ) in order to satisfy certain picky Sun
146      preprocessors
147    o re-arrange diagnostics pkg initialisation:
148     - allow each package to extend the available diagnostics list
149     - add some checking and fix small problems (multi-threaded, ...)
150     - new S/R diagnostics_fill (replace fill_diagnostics):
151       look through the short list of active diag. (instead of the long list)
152       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
153    
154    checkpoint57a_post
155    o this set of changes restores TAMC compatibility
156      tested for global_ocean.90x40x15 adjoint on trough
157      (what a pain)
158    
159    checkpoint57a_pre
160    o some modifs in tools/build_options for sunos
161    o call ctrl_pack for ctrl at end for optimcycle=0
162    
163    checkpoint57
164    o add horizontal bi-harmonic viscosity for vertical velocity
165      - new parameter viscA4W (defaults to viscA4)
166      - affects only non-hydrostatic code
167      - to be done: no-slip lateral boundary conditions
168    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
169    o implement Implicit Vertical advection for pTracers
170    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
171      (implemented also for implicit vertical diffusion & advection)
172    o OBCS: extend application of tracer open boundary conditions
173      to a strip beyond the boundary of width Olx/Oly
174    o add call monitor to TAF set of required calls (flow directives)
175      and include in natl_box_adjoint
176    o untangle a few ifdefs related to cost, ctrl, autodiff
177      untangel a few ALLOW_ECCO_OPTIMIZATION
178    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
179      (theta2, salt2 in ecco_cost_weights)
180    
181    checkpoint56c_post
182    o OBCS as control variables
183      - update ctrl_ad_diff.list, obcs_ad_diff.list
184      - remove balance of obcs controls from default
185      - fix index bug nobcs in ctrl_init
186      - fix dummy fields filen in ctrl_pack
187      - add dummy weights for obcs
188    o lsopt: comment out fort.94 output
189    o optim:
190      - remove unnecessary header files
191      - adjusted namelists
192      - add xerbla.F to Makefile
193    o exf:
194      - multiple modifications of exf_check_range
195      - unit change in exf_init_runoff from [m/year] to [m/s]
196    o mdsio:
197      - i/o-vector change debugLevel from debLevA to debLevB
198    
199    checkpoint56b_post
200    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
201      is called from DO_THE_MODEL_IO
202      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
203      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
204      - clean up PTRACERS_WRITE_TIMEAVE a little
205    o add another verification experiment that tests both the cfc-pkg and
206      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
207      reactive tendencies treated inline with regular timestepping
208    o testreport previously did a lousy job of comparing small numbers, so
209      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
210      implemented in the little c-progam tmp_cmpnum.c which is embedded in
211      testreport.
212    o ptracers_monitor: bug fix for MPI
213    
214    checkpoint56a_post
215    o GCHEM: finish reorganizating the package
216      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
217        (introduces another 3D-array for each passive tracer, but only if
218        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
219        gchemTendency is not needed because the timestep is done separately)
220      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
221      - GCHEM is now---more or less cleanly---separate from PTRACERS
222      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
223        so clear to me how that should be done in a general way.
224    o CFC: improve formatting of output in CFC_ATMOS
225    o PTRACERS:
226      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
227        that ALL experiments with ptracers enable can be checked. This makes
228        GCHEM_MONITOR obsolete.
229      - include a runtime parameter PTRACERS_monitorFreq that defaults to
230        monitorFreq
231      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
232    o add PTRACERS (PTR0[1-5]) to testreport output
233    o exf_check_range:
234      * default changed to .TRUE.
235      * will check values for niter0 if debLevA, every timestep if debLevB
236      * STOP in exf_check_range if 'out of range'
237      * range chosen generous to allow for potential extema
238      TBD: a version with stricter range
239           permitted range would be runtime parameters
240    o GMredi:
241      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
242      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
243      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
244    o GCHEM:
245      - move call to GCHEM_FORCING_SEP, so that it is now called before
246        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
247      - introduced a useGCHEM runtime flag and applied it everywhere.
248      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
249        this flag is now only visible within GCHEM-pkg routines.
250      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
251        be replaced by a 3D array that is computed before thermodynamics; for
252        this, the tracer ID iTracer had to be included into the parameter list
253        of ptracers_forcing
254      - set up forward_step to call gchem_forcing, that will replace
255        gchem_forcing_int in ptracers_forcing
256      - cleaning up
257    o small cleaning of exch2: remove files that are also in eesupp/src
258    
259    checkpoint56
260    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
261    o mnc: cleanup "full" files--fixes out-of-memory problem
262    o ECCO-GODAE
263      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
264      * fully merged and updated from SIO code
265        windstress sign change affects
266        - exf_inscal_[u/v]stress
267        - sign of xx_tau[u/v] adjustments
268        - signs in cost_scat
269      * ctrl_get_gen: avoid update of tau[u/v] for first few days
270      * natl_box_adjoint updated and compressed
271      * 2-level checkpoint switch added
272        (tested in EXP. 1 of natl_box_adjoint)
273      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
274    o SVD
275      * first complete, non-hacked version for SVD calculations
276      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
277        performed via direct access files admtlm_vector.it????
278        (via ctrl_[un]pack)
279      * optimcycle is used for ARPACK iteration counter
280        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
281      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
282        and add linear transforms where necessary
283      * controls are initial/final SST, SSS (can be extended; need to check
284        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
285    o mdsio: filename info to both stderr, stdout
286    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
287      from sign change
288    
289    checkpoint55j_post
290    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
291      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
292    o add consistent build directories and .cvsignore files to verification
293    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
294    o make all subroutines 30 or less characters in length for certain older
295      compilers to work (a thorough search only turns up two routines in
296      pkg/ptracers)
297    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
298      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
299    
300    checkpoint55i_post
301    o change arrays for total vertical diffusivity (2.D if explicit,
302      3.D if implicit) ; each ptracer uses its own background value.
303    o added mnc/NetCDF output capability to ocn_compon_interf
304      - added bits to verification/cpl_aim+ocn so that it can run on
305        ITRDA and other clusters without the mpirun "-wd" option
306    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
307      configuration
308    o give MNC the ability to create additional files rather than
309      exceeding a specified file size limit "MNC_MAX_FILESIZE"
310      - the default is just less than 2GB which is a practical limit
311        on many systems
312    o Compute the non-local term using either KPP vertical diffusivity (=default)
313       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
314    
315    checkpoint55h_post
316    o add verification test "vermix"
317    o remove all the *_ioinc flags and replace with the single global
318      outputTypesInclusive flag
319    o allow to set a vertical profile of vertical diffusivity for T & S
320    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
321    o useMNC moved from data.mnc to data.pkg
322    
323    checkpoint55g_post
324    o Renaming carbon AD experiments to comply with testreport conventions
325    o Updating adjoint of Held-Suarez hs94.1x64x5
326    o Fixing directives for non-ECCO forward_step, after ECCO directives
327      have been fixed to avoid recomp. of do_oceanic_phys
328      Works well for global_ocean.90x40x15,
329      but recomp. issue remains for carbon
330    o Updating adjoint output for natl_box_adjoint after
331      pkg/ecco has been modified (see taga c55d_post)
332    
333    checkpoint55f_post
334    o rename to timeave_init_fixed
335    
336    checkpoint55e_post
337    o some delicate re-shuffle of store directives to avoid one
338      extra call of do_oceanic_physics
339      affects ecco_the_main_loop.F, do_oceanic_physics.F
340      checkpoint_lev1_directives.h
341    o NB: this may break global_ocean adjoint temporarily,
342      but it is clear how to fix it. Will do later, need this now.
343    
344    checkpoint55d_post
345    o ECCO specific cost function terms (up-to-date with 1x1 runs)
346    o ecco_cost_weights is modified to 1x1 runs
347    o modifs to allow observations to be read in as
348      single file or yearly files
349    o enable to read exf forcing fields as either
350      single file or yearly files (flag useExfYearlyFields)
351    checkpoint55d_pre
352    
353    o switch between 2-level and 3-level checkpointing
354    o add ability of MNC to write local and "partial" (eg. 2D slices where
355      the full 3D field is never actually stored) arrays to NetCDF files
356      with the correct (that is, the complete multi-dimensional) set of
357      array indicies
358      - used in mom_vecinv() to write the diagFreq output
359      - tested (demonstrated) in verification/aim.5l_cs
360    o further mnc-ification
361      - add verification/lab_sea to the list with mnc setups
362      - fix undefined mnc v-names in cd_code
363      - add kpp to mnc output (both snapshot and timeave)
364    o non-hydrostatic code
365      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
366        in calc_gw.F
367      - defaults to viscAh
368      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
369        friction or Leith) in non-hydrostatic mode, as long as there is
370        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
371    o pkg/cost
372      extend simple cost functions to treat time mean quantities
373      (T,U,V) via cost_accumulate_state from cost_tile
374    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
375        be 2 times larger than the minimum size the advection scheme requires.
376        now get a perfect conservation of salt in advect_cs test-exp (updated)
377    o GGL90 (Gaspar's TKE mixed layer)
378      - add horizontal diffusion of TKE, requires exchanges in
379        do_fields_blocking_exchanges, horizontal diffusivity is zero by
380        default. In OPA there is no horizontal diffusion of TKE but the
381        mixing coefficients are computed from a horizontal average of TKE of
382        6 points or so. I think that diffusion has a little more physical
383        justification.
384      - clean up ggl90_calc in the hope of reducing memory usage (this hope
385        was in vain)
386      - mask tke-variable in ggl90_init
387    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
388    o fix biharmonic diffusion on CS-grid.
389    o more obcs stuff
390      - added obcs_external_fields_load as an alternative to the EXF-pkg option
391        for reading boundary values. This routine is called from
392        obcs_prescribe_read
393      - updated obcs_check
394      - changed sponge layer relaxation parameter units for days to seconds
395      - turned off sponge layer by default
396      - changed argument list of OBCS_CALC to myTime+deltaTclock
397      - fixed about 35 bugs in obcs_external_fields_load
398    
399    checkpoint55c_post
400    o obcs stuff
401      - new runtime flags useOBCSprescribe, useOBCSbalance
402      - re-arranged obcs_calc
403      - moved exf_getobcs to obcs_prescibe_read
404        obcs_prescibe_read is called after ORLANSKI stuff
405        and independent of it (executable can contain all).
406      - updated obcs_check
407      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
408        These may be necessary only if tangential velocities are
409        prescribed at OB, not sure, needs testing.
410    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
411      which simplifies the calls and passes the ifc check-bounds test
412    
413    checkpoint55b_post
414    o add a 2D scalar, Z location, exchange_2 routine.
415    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
416      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
417      affects advect_cs results (for the wrong reason): update output.txt
418    o use a more standard discretization for biharmonic viscosity ;
419     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
420      affects results of dome set-up: update output.txt
421    o fix gad_advection.F (CubedSphere part), back to version 1.23
422    o fix bug in mom_vi_del2uv.F (CubedSphere part).
423    
424    checkpoint55a_post
425    o merged code to
426      * prescribe/read time-dependent open boundaries
427        (works in conjunction with exf, cal)
428      * sponge layer code for open boundaries
429      * each boundary N/S/E/W now has its own CPP option
430        (healthy for the adjoint)
431    
432    checkpoint55
433    o up-to-date adjoint of previous breaks
434      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
435      - global_ocean_ebm: adjoint still needs fix (TLM ok)
436      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
437      - carbon: * remove tr1-related adjoint verification
438                * add ptracer as control variable
439    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
440      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
441    
442    checkpoint54f_post
443    o in verification/carbin/ remove experiment related to
444      ALLOW_PASSIVE_TRACER (array tr1 etc)
445      code_ad/ input_ad/ results_ad
446    
447    o add two new packages
448      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
449        + subject to optimization (memory)
450      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
451        + subject to reordering (many GOTOs in the original code)
452        + so far opps is called for every (i,j) point, and then operates in
453          the vertical; one may want to reorder the scheme in order operate in
454          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
455          fields)
456    o overhaul of IO so that we now have flags for MDSIO and/or MNC
457      - all verification tests compile and run with linux_ia32_g77
458      - defaults are compatible with current input files--nothing
459        should change if you were not previously using MNC
460      - MNC output has been added in numerous places (eg. timeave)
461        but there are still a few writes not yet do-able with MNC
462        (this is in progress)
463      - flags now allow for either/or/both use of MDSIO and MNC and
464        documentation will soon follow
465      - numerous small formatting cleanups for ProTeX
466    o add version info (via BUILD_INFO.h) to MNC and stdout
467    
468    checkpoint54e_post
469    o add two new packages
470      - pp81 (Packanowski and Philander, 1981), Richardson number and
471        stratification dependent mixing
472      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
473      - these scheme operate in a similar manner as KPP (without ghat, of
474        course), however there is only one diffusivity that is used for both
475        temperature and salinity (and passive tracers)ç
476    o add offline package
477    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
478      provided by Stephanie Dutkiewicz
479    o genmake2: add ability to search for C compilers and cleanup test output
480      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
481    
482    checkpoint54d_post
483    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
484    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
485      leading to additional shift by 5 days each year of integration
486       (i.e. leading to considerable offset over the years)
487    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
488    o start with no AB and no initial filtering (staggerTimeStep):
489      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
490    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
491      (external loading & cpl import/export stay in forward_step.F)
492    o update coupling interface to work with new staggerTimeStep
493    o change MDSIO ptracers_pickup.
494    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
495    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
496    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
497    
498    checkpoint54c_post
499    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
500      this affects (truncation error) output.txt of test-exp:
501       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
502    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
503    o change Qnet to always be the net heat flux, (+upward).
504      affects (truncation error) output of natl_box exp.: updated
505    o define the max number of passive tracers in PTRACERS_SIZE.h
506    o start to test mnc routinely in exp0
507    o add sea-ice loading (sIceLoad) as a new forcing field.
508    
509    checkpoint54b_post
510    o add testreport "-j JOBS" option for parallel builds (tested and pretty
511       impressive on Altix and Opteron systems)
512    o diagnostics can now write NetCDF files through the mnc package
513    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
514    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
515    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
516      affects (truncation error) output of lab_sea & natl_box exp.: updated
517    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
518    
519    checkpoint54a_post
520    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
521    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
522    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
523    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
524      + internal_wave (shift in writing cg2d_ini_res)
525    checkpoint54a_pre
526    
527    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
528      - modified verification/lab_sea and natl_box_adjoint accordingly
529    
530    checkpoint54
531    checkpoint53g_post
532    o prepare splitting of thermodynamics: store convect.counter in common block
533    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
534      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
535    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
536    o new parameter "nShapS": allow to treat differently S from T (nShapT)
537    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
538    o restore adjointability
539    
540    checkpoint53f_post
541    o modifications that affect AIM experiment results (update output.txt):
542      - no advection of S at top interface Nr (pkg/generic_advdiff)
543      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
544    o AIM pkg:
545      - include stability function into surf.Flux derivative relative to Tsurf
546      - calculate clear-sky radiation & surface temp. change (for diagnostics)
547    
548    checkpoint53e_post
549    o merged cylindrical coord configuration
550    o added rotating_tank experiment
551    checkpoint53e_pre
552    
553    checkpoint53d_post
554    o faulks upgraded: re-generate output.txt that have changed:
555       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
556    o Added Bryan and Lewis, 1979, vertical diffusivity profile
557    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
558    o added Sadourny discretization of Coriolis
559      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
560      - re-enabled use of omega3 (useAbsVorticity)
561    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
562      vector-invariant equations
563      - note: does *NOT* yet use same variable visc. for no-slip BC's.
564    o recoded the lateral boundary conditions for non-hydrostatic w, this time
565      hopefully without new bugs
566      - still to do: biharmonic friction for non-hydrostatic w
567    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
568    o regenerated output for global_ocean_ebm (using -ieee)
569    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
570      of mom_common/
571      - simple re-arrangement of instructions within computing loop
572    checkpoint53d_pre
573    
574    checkpoint53c_post
575    o new version of coupler for AIM+thSIce and Ocean models
576     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
577     - land: change Evaporation of snow
578     - aim with thSIce: fix bug in snow-precip.
579    o changes to calc_gw.F
580     - bug fix for w^2 term near the bottom boundary
581     - (hopefully) improve the lateral slip boundary condtions for use with
582        partial/looped cells
583      - because the bug fix changes two verification experiments anyway (exp5
584        and plume on slope), change the lateral boundary condition from half slip
585        to the value of no_slip_sides
586    o ebm package wasnt quite up to the parallel task. Fixed that.
587    o Adjoint of EBM package + verification
588      * TLM OK
589      * ADM not sufficient accuracy yet (needs further testing)
590    
591    checkpoint53b_post
592    o Commiting new energy balance model to repository
593      * package is pkg/ebm
594      * verif. is verification/global_ocean_ebm
595      * references are in ebm_driver.F
596    C      * X. Wang, P. Stone and J. Marotzke, 1999:
597    C        Global thermohaline circulation. Part I:
598    C        Sensitivity to atmospheric moisture transport.
599    C        J. Climate 12(1), 71-82
600    C      * X. Wang, P. Stone and J. Marotzke, 1999:
601    C        Global thermohaline circulation. Part II:
602    C        Sensitivity with interactive transport.
603    C        J. Climate 12(1), 83-91
604    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
605    C        Destabilization of the thermohaline circulation
606    C        by atmospheric eddy transports.
607    C        J. Climate 7(12), 1870-1882
608    o Will need long integration testing.
609    checkpoint53b_pre
610    
611    o created pkg/mom_common in preparation for variable viscosity code
612    o renamed and split ini_mnc_io
613    o pkg/land: only liquid water can diffuse or run-off
614    o AIM using land: soil wetness availability account for snow
615    o added printMapIncludesZeros to EEPARMS namelist
616    
617    checkpoint53a_post
618    o restore TAMC compatiility for exf_constants.h
619      (no usage of _d in .h)
620    o Additional storing in KPP in an attempt to fix
621      TAMC problem with adjoint of KPP code.
622      (no success...)
623      Identical code works fine with TAF.
624    o Fixed verification/natl_box_adjoint experiments.
625      Initial conditions for Experiments 4 and 5 are now
626      set to "SEAICE_initialHEFF=0", which is more reasonable,
627      and hence gives results closer to that of Experiment 2.
628      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
629    
630    checkpoint53
631    o stable checkpoint with up to date adjoint
632      TLM tests only run for 1st grdchk at the moment. Its unclear if
633      this is a code problem or a problem with resetting code for g_
634      variables that is being autogenerated wrong.
635      Otherwise:
636       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
637       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
638         are both still in chaos following their security messes.
639    
640    checkpoint52n_post
641    o various build (mostly genmake2) changes including:
642      - ability to build/run more easily within Cygwin and MacOS X
643      - more complicated Makefiles with a stronger dependence on Gnu Make
644    o pkg/seaice modifications
645      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
646        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
647        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
648      - changed proxy for geostrophic velocity and updated
649        verification/lab_sea/results/* accordingly
650      - removed ADI dynamic solver from pkg/seaice
651      - replaced all occurrences of 1/CSTICE or 1/CSUICE
652        they caused a segmentation fault under certain circumstances
653      - removed unused field WATR
654    o bug fix in exf-package:
655      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
656         now reflect that.
657    o small fixes in the cal-package:
658      - set reference date to first of January for the 'model'-calendar
659      - failing of cal_CheckDate in cal_FullDate now actually results in a
660        warning
661    o small modifications in exf-package to increase flexibility:
662      - change climtempfreeze from a constant to a runtime parameter that
663        is specified in data.exf_clim (default = -1.9)
664      - introduce runtime parameter windstressmax (default = 2.0) that is
665        specified in data.exf
666    o fix in pkg/thsice:
667      - update Evap (Tsf changes) to be consistent with Latent heat flux
668      - maintain snow precipitation unchanged (even if Tsf >=0).
669     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
670    
671    checkpoint52m_post
672    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
673      this does not change any of the results, because myIter=0 in swfrac always
674      lead to jwtype=2 (the default anyway), but the call makes little sense
675      as a default
676    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
677    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
678      atmospheric model (AIM) to use it ; add a "slab ocean" component.
679    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
680    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
681    o extending useSingleCpuIO option to work with new exch2 I/O format
682      - old-style, missing-tile I/O is still accessible by defining CPP
683        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
684    o monitor package can write to NetCDF files and/or STDOUT
685    o fix re-definition bug in MNC_GRID_INIT_ALL()
686    o doc/api_reference added
687      - a framework for building an API Reference Manual using all
688        the "protex" comments embedded in the code
689      - see pkg/generic_advdiff, pkg/mnc for examples
690    o MNC:
691      - make myThid the last argument for all subroutines
692      - new default for the grid files: NO halos
693      - add useMNC and other run-time flags
694      - separate per-file-group handling of the unlimited dimension
695      - early initialization of MNC w/ flags read at the eeboot stage
696        and lookup tables set in initialize_fixed
697      - write all MNC output to a freshly-created directory
698    o thermodynamics sea-ice (thsice) is now tested with testreport.
699    o test exp. advect_cs: use the standard cs32 grid ; update output.
700    o Added functionality to grdchk:
701      pick global i,j,k position (or nearest wet) where to perform check.
702    
703    checkpoint52l_post
704    o new land formulation:
705      a) use ground enthalpy as prognostic variable to ensure exact
706         energy conservation.
707      b) account for water temperature and for latent heat of freezing
708         in all processes (rain, run-off, ground storage)
709      c) compute surface and ground temperature implicitly.
710    o aim_v23 modification for new land model:
711      a) Treat separately land / ocean / sea-ice surface fluxes
712         to allow implicit computation of land & sea-ice surface temp.
713      b) add snow precipitation.
714    checkpoint52l_pre
715    
716    o fix problem (when 1 tile is empty) in min/max monitor.
717    o fix bug in timeAve (u,vZetatave in common block)
718    o no restoring terms under ice for pkg/seaice
719    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
720    o bug fix for pkg/seaice pickups
721    o change MNC call locations and add coordinate attributes
722    o mask vorticity at the corner ; affects global_ocean.cs output
723    o fix ini_curvilinear_grid ; test CS experiments with mpi
724    o aim.5l_cs: modify sea-ice fraction input file ; update output
725    o exf: Adding simple range check routine for exf fields after read
726    
727    checkpoint52k_post
728    o removed top-level directory "diags"
729      - we migrated these functions to pkg/timeave a long time ago
730    o fixed bug introduced in pkg/monitor
731    o accuracy ctrlprec = 32 insuffient for gradient checks using
732      averaged fields (I/O via cost_averages)
733      -> use ctrl.h in active_file*.F to control I/O precision.
734    o paramter list of CALL ADTHE_MAIN_LOOP
735    o added initial do_the_model_io to ecco
736    o set all ...Freq to zero after cost_final
737      taveFreq, dumpFreq, pChkptFreq
738    o MAIN and ECCO differentiability restored
739    
740    checkpoint52j_post
741    o fix nchklev in tamc.h for global_ocean...
742    o Bringing flow and store directives up-to-date
743    o Really weird thing!
744      call do_the_model_io from the_main_loop with parameters
745      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
746      TAF places a faulty re-call of initialise_varia
747      after cost_final call which should not be there!
748    checkpoint52j_pre
749    
750    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
751      error messages
752    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
753    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
754      debug output
755    o modfied mdsio_writefield.F to handle non-global files under exch2
756    o update AIM Cubed-Sphere exp (aim.5l_cs):
757      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
758    o update AIM Equatorial Channel exp:
759      use standard aim_v23 pkg and change the SST fields to be more realistic.
760    o globalFile now works with exch2
761    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
762      mon_vort3.F to make exch2 friendly with >1 tile per cube face
763    o limit timeave output for hi-res integrations
764    
765    checkpoint52i_post
766    o removed CPP_EEOPTIONS.h from verification/*/code
767    o updated the tiling for global_ocean_pressure
768    checkpoint52i_pre
769    
770    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
771      the old pkg/aim).
772

780    o added temporary hack for sea-ice dynamics on the cube:
781      metric terms are ignored and it is assumed that
782      there is no sea-ice on cube faces 1, 2, 4, and 5.
783    
784    checkpoint52f_post
785    o added exch2 cube routines to pkg/exch2

792      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
793    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
794      to work with implicit vertical advection and AB ;
795    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
796    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
797     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
798    checkpoint52e_pre
799    
800    o fix bug in impldiff when Nr=1 or Nr=2.
801    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
802    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
803    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2

810    o re-tiled many expts to allow comparison in multi-processor mode
811      - updated output accordingly
812      - changed hs94.128x64x5 to use intial T from file rather than use the
813        random number generator
814    o add infrastructure in model routines for fizhi and gridalt packages
815    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
816    o changes to permit hi-res, cubed-sphere, configuration
817      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
818      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
819      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
820        of surface winds for the cube
821      (A verification experiment, based on global_ocean.cs32x15, but with
822       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
823       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
824       complete with example surface forcing files and matlab scripts to look
825       at the output and compare it with that of global_ocean.cs32x15.)
826    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
827       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
828       to conform to the common rule.
829    o check-in the first version of the coupler + interfaces for multi-components
830       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
831       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
832       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
833       - ocean and atmos. share the same horizontal grid (no interpolation).
834       - exchanges between component and coupler is done in forward_step
835    o new verification experiment, cpl_aim+ocn:
836       coupled ocean - AIM atmosphere on cs32 grid.
837    
838    checkpoint52d_pre
839    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
840    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
841    
842    checkpoint52c_post
843    o Fixing OPTIONS files for use of exf:
844      - ALLOW_ECCO not needed
845      - ECCO_CPPOPTIONS.h should not be included from
846        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
847        as has been the case in the past
848      - All cal/exf related options are currently set in
849        single header file. Should remain so until we
850        agree on a consistent new policy.
851    o Removed all CPP options for cal package.
852      cal has no more CPP options.
853    o modified STOREs in GAD_ADVECTION
854    o corrected key comp. for passkey
855    
856    checkpoint52b_post
857    o new version: "thsice" of thermodynamic sea-ice pkg:
858     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
859     - modify fluxes but do not change theta directly;
860     - light cleaning of bulk_force pkg (still needed with thsice).
861     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
862       + output_thsice.txt to test thsice & bulk_force pkgs.
863    o put back grid & coriolis monitor output.
864    checkpoint52b_pre
865    
866    o call "do_the_model_io" at the beginning (=> dump initial state)
867    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
868    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
869      (need info on NUMBER_OF_PTRACERS)
870    o missing PTRACERS headers in some routines
871    o default tamc.h in pkg/autodiff supposed to crash
872      to ensure proper customization
873    
874    checkpoint52a_post
875    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
876      - moved surfaceTendencyTice from pkg/seaice to main code
877      - subroutine FREEZE_SURFACE now limits only surface temperature
878        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
879        => new output.txt for global_ocean.cs32x15 & global_with_exf
880      - keep the old version of FREEZE for backward compatibility;
881        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

890    o some bug fixes for #undef REAL4_IS_SLOW
891    
892    checkpoint52 = ecco_c52_e35
893    o after testing adjoints of checkpoint51u_post
894    
895    checkpoint51u_post
896    o this is the post-merge tag of the ecco-branch
897      (needs another clean checkout and re-testing)
898    o various natl_box_adjoint configs and results
899      but no input fields
900    o obcs adjoint not yet merged!
901    o adding ECCO global 1x1 and 2x2 degree configs
902    o updated/extended some store directives for seaice
903    o pkg/ecco now containes ecco-specific part of cost function

905      supersede those in model/src/
906      previous input data.cost now in data.ecco
907      (new namelist ecco_cost_nml)
908    o in ctrl/ cleaned some cross-dependencies and updated CPP options
909    
910    checkpoint51t_post
911    o this is the pre-merge tag of the ecco-branch
912    
913    checkpoint51s_post
914    o cleanup: removed various obsolete #define-s
915    o pkg/grdchk
916      - renamed 'ph-grd 3' to 'grad-res'
917      - merged from ecco-branch
918        (remaining bug fixes for obcs gradient checks)
919      - additional high-precision output for testreport
920        (grep for 'precision_grdchk_result')
921    
922    checkpoint51r_post
923    o cleaned up or removed CPP_OPTIONS.h files
924    o updated results for some of the tests to reflect the new
925      optfiles (-ieee: -O0 instead of -O3)
926    
927    checkpoint51q_post
928    o cd_code:
929      - moved cd_scheme.F -> cd_code_scheme.F

940      - confined inclusion of AD_CONFIG.h to where necessary.
941    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
942    
943    checkpoint51p_post
944    o create initial cd_code package
945      - WARNING: the initialization of fields within packages
946        is broken because INI_FIELDS (where READ_CHECKPOINT is
947        called) is called *before* PACKAGES_INIT_VARIABLES.
948        This seems to be backwards since
949        1) its important to initially zero the entire field including
950           the "halo" region
951        2) zeroing needs to be done *before* reading pickup info
952           and the pickup call might or might not happen in any
953           particular run
954      - this needs an overhaul for R2
955    o cleanup verification/*/code/GMREDI_OPTIONS.h
956    o cleanup testreport
957    
958    checkpoint51o_post

993         global_ocean.cs32x15, and global_with_exf)
994    o added surface flux output variables to TIMEAVE_STATVARS
995    
996    checkpoint51n_pre
997    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

1181      - split exf_getffields.F into new exf_bulkformulae.F
1182      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1183      - updated adjoint/makefile and relevant verif. accordingly
1184    
1185    checkpoint50f_pre
1186     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
1187          + change Evap over land. (update aim.5l_cs output)
1188     o added missing .cvsignores and made uniform across expts
1189     o changed configuration of tidal_basin_2d expt
1190     o added pkg/debug functions for tracing code in fatal crashes
1191     o tidied pkg/monitor to use MONITOR_OPTIONS.h
1192     o new fn in pkg/monitor to stop model if solution grows too big
1193     o removed lots of single quotes from comments
1194    
1195    checkpoint50e_post
1196    o make KPP work with PTRACERS
1197     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1198       nearly a copy of kpp_transport_s
1199     - there is no analogue to SurfaceTendencyS, so I have to use
1200       gPtr(of the surface layer) instead
1201    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1202    checkpoint50e_pre
1203    
1204    checkpoint50d_post
1205    o change kpp output from multiple-record state files to single-record state
1206      files analogous to write_state.F
1207    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1208      analogous to the cg2d-related output.
1209    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1210      so that writing to internal file fn (with length 512) fails.
1211    checkpoint50d_pre
1212    
1213    checkpoint50c_post
1214    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1215    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1216    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1217    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1218    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1219    
1220    checkpoint50c_pre
1221    Merging from release1_p13:
1222    o bug fix for pkg/seaice dynamic solver
1223    o Added SEAICE_initialHEFF to pkg/seaice
1224    
1225    checkpoint50b_post
1226    o store u*,v* in gU,V instead of in guNm1,gvNm1
1227    o in order to put the momForcing out of the Adams-Bashforth:
1228      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1229      to timestep.F
1230    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1231    o re-generate output for highly sensitive test-exp:
1232       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1233    
1234    checkpoint50b_pre
1235    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1236    o corrected CPP option mismatch in exf_Bulk... functions for case
1237      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1238    
1239    checkpoint50a_post
1240    o Bug fix for merging between c50 and KPP.
1241      ikey was passed from thermodynamics to kpp_calc via
1242      common block rather than being recomputed in kpp_calc,
1243      in contradiction with new key itdkey.
1244      New key ikppkey created, and tamc.h headers updated.
1245    
1246    checkpoint50
1247    - 2nd step of merge with ecco-branch:
1248      merge changes in ecco-branch back into main trunk
1249    - bug fix in find_alpha
1250    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1251    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1252    - merged some sliced AD support routines
1253    
1254    checkpoint49
1255    merged from ecco-branch:
1256    o exf:
1257      - Enable initialisation of forcing fields to constant
1258        (runtime) values.
1259      - in exf_getffields.F
1260        Reduce i-/j-loop to interior domain, discarding overlaps.
1261        That also fixes wrong TAF-key computations for key_1, key_2
1262        with bulf formulae.
1263      - exf_init.F modify #ifdef for exf_init_evap
1264      - exf_getffieldrec.F, ctrl_getrec.F
1265        The following INT-usages are not safe:
1266          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1267          fldcount = int(fldsecs/fldperiod) + 1
1268        and were modified.
1269    o autodiff: checkpoint_lev...
1270      - updated storing for bulk formulae (some arrays were missing)
1271      - added state for seaice package
1272      - synchronized with main branch
1273    o DIVA:
1274      Modif.s in
1275      - the_main_loop.F
1276      - the_model_main.F
1277      and added cost_final_restore.F cost_final_store.F
1278      o With these changes, it is possible to fully separate
1279        the first forward run to compute the cost function (mdthe_main_loop)
1280        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1281        into separate model executions.
1282        This enables better tuning of DIVA to given queue sizes.
1283      o Loss of cost function value in consecutive DIVA runs is
1284        fixed by storing to 'costfinal' file.
1285      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1286        beginning/end of adjoint integration is accounted for.
1287      The current changes apply to TAF-1.4.26.
1288      TAF has one remaining bug, requiring one manual change
1289      (see MITgcm manual).
1290    o cal: synchronized between MAIN and ecco-branch
1291    
1292    checkpoint48i_post
1293    o Changes to restore differentiability of code w.r.t. previous tag
1294      (mostly adding new routines to make list and replacing
1295      pressure by totPhiHyd).
1296    o Updated and merged grdchk package
1297      - has both ADM and TLM checks
1298      - works for single- and multi-proc.
1299      - output cleaned
1300      - worked successfully for parallel DIVA
1301    o genmake:
1302      - Adding -platform=SP4
1303      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1304    o Modif. for DIVA:
1305      ctrl_unpack should not be called in intermediate DIVA interval.
1306      (similar thing would apply for active files such as
1307      tbar, sbar, psbar, which should not be reinitialised;
1308      only relevant for ecco-branch)
1309    
1310    checkpoint48h_post
1311    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1312    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1313    o Added SEAICE_initialHEFF to pkg/seaice
1314    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1315    
1316    checkpoint48g_post
1317    --- EOS:
1318    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1319      store total Potential in totPhyHyd for diagnostics & EOS.
1320    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1321    --- Pressure/geopotential gradient:
1322    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1323    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1324      ( changes results of global_ocean_pressure )
1325    o NLFS + z-coord.: add eta*Rho' contribution.
1326    o accurate phiHyd when using interface-W at the middle between 2 centers
1327     ( changes results of ideal_2D_oce )
1328    o includes r* 2nd term in potential gradient.
1329    
1330    checkpoint48f_post
1331    Merging from release1_p12:
1332    o Modifications for using pkg/exf with pkg/seaice
1333      - improved description of the various forcing configurations
1334      - added basic radiation bulk formulae to pkg/exf
1335      - units/sign fix for evap computation in exf_getffields.F
1336      - updated verification/global_with_exf/results/output.txt
1337    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1338      (SBO) core products, including oceanic mass, center-of-mass,
1339      angular, and bottom pressure (see pkg/sbo/README.sbo).
1340    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1341      to avoid negative values in shallow regions.
1342      - updated verification/natl_box/results/output.txt
1343      - updated verification/lab_sea/results/output.txt
1344    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1345    o Added useSingleCpuIO option (see PARAMS.h).
1346    o Updated useSingleCpuIO option in mdsio_writefield.F to
1347      work with multi-field files, e.g., for single-file pickup.
1348    o pkg/seaice:
1349      - bug fix in growth.F: QNET for no shortwave case
1350      - added HeffFile for specifying initial sea-ice thickness
1351      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1352    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1353      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1354    o pkg/seaice:
1355      - adjoint-friendly modifications
1356      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1357    
1358    checkpoint48e_post
1359    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1360    o dynamics: change definition of computational domain & adapt mom_fluxform
1361      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1362    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1363        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1364        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1365        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1366        inverted_barometer solid-body.cs-32x32x1
1367      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1368    
1369    checkpoint48d_post
1370    o in preparation for r*:
1371     a) use pre-computed gradient of hydrostatic potential:
1372        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1373     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1374        => affects results of glob_oce_pressure (different truncation error)  
1375      update output.txt of ideal_2D_oce & global_ocean_pressure
1376    
1377    checkpoint48d_pre
1378    o in preparation for r*:
1379      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1380      pass the 2 comp. of the grad. as arguments to momentum S/R.
1381      but for the moment, only used if it does not change the results.
1382    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1383    
1384    checkpoint48c_post
1385    Modifications in treatment of initial flux forcing controls
1386    to avoid extra storing of flux fields.
1387    
1388    checkpoint48c_pre
1389    o Added tidal_basin_2d experiment (currently 1D!)
1390    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1391    
1392    checkpoint48b_post
1393    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1394     (modification to pressure gradient not yet implemented)
1395    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1396      (for U & V) that are used for vertical advection of momentum.
1397    
1398    checkpoint48a_post
1399    o In preparation for r*, use temp. array to compute vertical transport
1400       in flux-form momentum pkg. => change results of few test-exp.
1401      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1402                        lab_sea, natl_box & plume_on_slope
1403    
1404    checkpoint48
1405    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1406    
1407    checkpoint47j_post
1408    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1409    o moved adexch from forward_step to addummy_in_stepping
1410    o added exch in ctrl_map_...
1411    o aveFreq.=0. at end of cost_final to avoid overwrite in
1412      reverse checkpointing loop
1413    o Yet more changes in gmredi:
1414      * adgmredi_calc_tensor
1415        avoiding all recomputation of gmredi_slope_limit
1416      * adgmredi_x/y/rtransport
1417        added flag for excessive storing to avoid recomp. of
1418        u/v/rtans, dTdx/y/z
1419        -> this is not really necessary and very memory-consuming
1420      * adgmredi_slope_psi:
1421        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1422      * gmredi_slope_limit
1423        re-activated full calculation of taperfct for case 'ac02'
1424    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1425    
1426    checkpoint47i_post
1427    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1428    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1429      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1430    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1431    o gmredi: fix few bugs.
1432    
1433    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1434    This will be a good checkpoint to plug into the ecco-branch.
1435    o few modif.'s to get latest version adjointed
1436      (mainly kick out code in ini_linear_phisurf)
1437    o modif's to run adjoint with exactConserv
1438    o case GM_BOLUS_ADVEC should be cleaned
1439      S/R gmredi_slope_psi should be cleaned
1440    o verification/carbon now has exactConserv=.TRUE.
1441    
1442    checkpoint47g_post
1443    o time-average AIM output: becomes independent from statvars time-average
1444      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1445    o After TAF bug fix:
1446      Tested adjoint of gmredi package.
1447      Tests were done with checkpoint47 rather than with latest
1448      checkpoint47f_post since the latter is broken for the adjoint
1449      verification/carbon/ contains both ADM and TLM gradient checks.
1450    Here they are, before they get changed/lost/stolen.
1451    Mostly modif.'s to fix numerical sensitivities.
1452    Gradient checks OK for
1453    - GM_taper_scheme:
1454      * clipping
1455      * ac02
1456      * linear
1457      * glw91
1458      * dm95
1459      * ldd97
1460    - GMREDI_OPTIONS:
1461      * GM_VISBECK_VARIABLE_K
1462      * GM_NON_UNITY_DIAGONAL
1463      * GM_EXTRA_DIAGONAL
1464      * GM_BOLUS_ADVEC
1465    in conjunction with data.gmredi parameters to be checked in
1466    in a few minutes under verification/carbon/code/
1467    
1468    checkpoint47f_post
1469    Merging from release1_p10:
1470    o modifications for using pkg/exf with pkg/seaice
1471      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1472        and SEAICE_EXTERNAL_FLUXES
1473      - pkg/exf CPP options EXF_READ_EVAP and
1474        EXF_NO_BULK_COMPUTATIONS
1475      - usage examples are Experiments 8 and 9 in
1476        verification/lab_sea/README
1477      - verification/lab_sea default experiment now uses
1478        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1479    
1480    checkpoint47e_post
1481    o created a tag prior to creating a branch
1482    
1483    checkpoint47d_post
1484    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1485      at the bottom boundary had an erroneous half slip boundary condition
1486    o added bottom drag and no slip boundary condition capabilities to
1487      oceanic pressure coordinates code
1488    o added new verification experiment global_ocean_pressure, this experiment is
1489      also described in the tutorial section of the manual
1490    checkpoint47d_pre
1491    
1492    checkpoint47c_post
1493    o Added a verification experiment for a global cubed-sphere ocean run
1494      -  verification/global_ocean.cubed32x32x30
1495      -  uses pkg/therm_seaice and pkg/bulk_forcing
1496    
1497    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1498    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1499      when using P-coordinate; only implemented for atmospheric config.
1500    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1501      NOTES: requires option NONLIN_FRSURF to be "#define".
1502    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1503    
1504    checkpoint47b_post
1505    Merging from release1_p9:
1506    o pkg/seaice
1507      - removed GOTO's and added taf directives
1508      - double precision constants to reduce the g77 (Linux)
1509        to F77 (SGI) differences reported in release1_p8
1510    o tools/genmake
1511      - added SGI options
1512    o verification/testscript
1513      - updated to that of checkpoint47a_post
1514    o verification/global_ocean.90x40x15/input/eedata
1515      - modified for SGI f77 compatibility
1516    o verification/lab_sea
1517      - added description of sea-ice model
1518      - added missing matlab routines
1519      - added test of thermodynamics parallelization
1520    
1521    checkpoint47a_post
1522    o new pkg: aim_v23
1523     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1524       for now, keep the same surface forcing as before.
1525     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1526     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1527     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1528    o add diagnostic of surface correction term in monitor output
1529    
1530    o bulk_force and therm_seaice
1531    - Two packages:  bulk_force (Bulk forcing)
1532      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1533    - Earlier integration from Stephaine Dutkiewicz
1534      and Patrick Heimbach.
1535    - Two ifdef statements for compile time,
1536       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1537    
1538    checkpoint47
1539    differentiable version of checkpoint46n_post
1540    o bug fix in quasihydrostaticterms
1541    o * "clean" adjoint code (in terms of extensive recomputations)
1542        can now be obtained for all GMREDI options (i.e. for
1543        - GM_VISBECK_VARIABLE_K
1544        - GM_NON_UNITY_DIAGONAL
1545        - GM_EXTRA_DIAGONAL
1546        - GM_BOLUS_ADVEC )
1547      * However, wrong gradient check problem remains unsolved.
1548      * New CPP options have been introduced for different
1549        tapering schemes
1550    o external_fields_load now part of differentiation list
1551    o pressure needs multiple storing;
1552      would be nice to have store_pressure at beginning or
1553      end of forward_step, e.g. by having phiHyd global (5-dim.)
1554      (NB: pressure is needed for certain cases in find_rho,
1555      which is also invoked through convective_adjustment).
1556    o recomputations in find_rho for cases
1557     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1558    o #define ATMOSPHERIC_LOADING should be differentiable
1559    o ini_forcing shifted to begining of initialise_varia
1560    o Incorporating QNVS line search routines into MITgcm
1561      (this is separate code, and therefore not under pkg)
1562      lsopt/, optim/
1563    o Updated verification/carbon/
1564      - #define GM_VISBECK_VARIABLE_K
1565      - GM_taper_scheme    = 'ldd97'    
1566    
1567    checkpoint46n_post
1568    Merging from release1_p8:
1569    o verification/natl_box:
1570      updating new external_fields_load routine
1571    o New package: pkg/seaice
1572      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1573      The sea-ice code is based on Hibler (1979-1980).
1574      Two sea-ice dynamic solvers, ADI and LSR, are included.
1575      In addition to computing prognostic sea-ice variables and diagnosing
1576      the forcing/external data fields that drive the ocean model,
1577      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1578      The implied surface heat flux is then stored in variable
1579      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1580      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1581      non-local transport term.  Because this call precedes model
1582      thermodynamics, temperature under sea-ice may not be "exactly" at
1583      the freezing point by the time theta is dumped or time-averaged.
1584      N.B.: fairly large differences in accuracy occur across
1585            different platforms/compilers; comparison between
1586            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1587            generated output gives:

1595    o GAD:
1596      - generated new common blocks to account for call of
1597        same gad routines with differing traceridentities
1598        (needed to modify tracerIdentity indices in GAD.h)
1599      - generated separate common blocks for case useCubedSphereExchange
1600        (Department of Futurology)
1601      - parameter lists to gmredi_?transport: added tracerIdentity
1602      - added new key indices to tamc.h
1603    o external_fields_load:
1604      - added this routine to TAF list
1605      - needed to make some common blocks global and additional storing
1606        along the same lines as exf package (checkpoint_lev?_directives.h)
1607    o exf:
1608      updated external forcing package
1609      - bug fixes carried over from ecco-branch
1610        (missing OBCS_OPTIONS.h in two routines)
1611      - enable easy to use "no forcing".
1612      - added exf I/O for atmospheric loading
1613      - added exf I/O for runoff data
1614      - transfered scaling between exf <-> MITgcm to exf namelist
1615    o Adding new verification experiment global_with_exf.
1616      This verification experiment is almost identical to the
1617      global_ocean.90x40x15 experiment, except that it uses
1618      the exf (and cal) package instead of the
1619      external_fields_load routine (cf README file).
1620    
1621    checkpoint46m_post
1622    o modified testscript to return -- when there are no lines of "%MON" output
1623    o added new flag "quasiHydrostatic" for QH mode
1624      and new routine quasihydrostaticterms()
1625    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1626      New routine: mom_u_coriolis_nh()
1627    o fixed sign of non-hydrostatic metric terms in u and v equations.
1628      Depend on correct sign of gravitySign.
1629    o added work.pc* to .cvsignore in aim directories using ifc
1630    o introduced flag for controllin non-hydrostatic metric terms
1631    o removed gravitySign from PARM04
1632    o switched to g77/ifc from pgf77 in aim experiments
1633    
1634    checkpoint46l_post
1635    o made convective adjustment work with pressure coordinates:
1636     - changed the direction of k-loop in convective_adjustment.F for the
1637       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1638     - adjusted the reference pressure k-index in convective_adjustment.F
1639     - adjusted the convection condition in convect.F (in analogy to
1640       calc_ivdc.F)
1641     - convective_adjustment no longer computes anything on the halos
1642     - removed the warnings about negative salinity from find_rho.F and
1643       find_alpha.F; instead the new routine look_for_neg_salinity, called
1644       at the beginning of find_rho, find_alpha, and find_beta, does a
1645       check of the entire slice, if CPP-option
1646       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1647    checkpoint46l_pre
1648    
1649    checkpoint46k_post
1650    o fixed the verification/global_ocean.90x40x15 experiment:
1651     - new bathymetry (the world according to A., JMC, and M.)
1652     - new initial fields and forcing fields (*.bin files)
1653     - new POLY3.COEFFS (for the next release one should switch to a full
1654       equation of state: JMD95P or MDJWF)
1655     - fixed several errors and redundancies in the data file
1656     - experiment uses looped cells
1657     - added matlab directory with diagnostic scripts for plotting of output
1658    
1659    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1660     - read AIM physics parameters from a file (data.aimphys)
1661     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1662    
1663    checkpoint46j_post
1664    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1665    o move wVel computation at the end of the time step, in S/R integr_continuity
1666    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1667    o update timeave pkg for wVel diagnostic.
1668    checkpoint46j_pre
1669    
1670    checkpoint46i_post
1671    o Clean up AIM package (and keep the results unchanged):
1672      include CPP_OPTION and use IMPLICT NONE in all routines ;
1673      declare all the variables _RL ; use _d 0 for all numerical constants.
1674      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1675    
1676    checkpoint46h_post
1677    o cleaned up the use of rhoNil and rhoConst.
1678      - rhoNil should only appear in the LINEAR equation of state, everywhere
1679        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1680        and the dynamical equations are all divided by rhoConst
1681    o introduced new parameter rhoConstFresh, a reference density of fresh
1682      water, to remove the fresh water flux's dependence on rhoNil. The default
1683      value is 999.8 kg/m^3
1684    o cleanup up external_forcing.F and external_forcing_surf.F
1685      - can now be used by both OCEANIC and OCEANICP
1686    checkpoint46h_pre
1687    
1688     Added code to convert surface volume flux (fresh water) into
1689     a mass flux when using P coordinates in the ocean (OCEANICP).
1690     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1691    
1692    checkpoint46g_post
1693    o Include a new diagnostic variable phiHydLow for the ocean model
1694      - in z-coordinates, it is the bottom pressure anomaly
1695      - in p-coordinates, it is the sea surface elevation
1696      - in both cases, these variable have global drift, reflecting the mass
1697        drift in z-coordinates and the volume drift in p-coordinates
1698      - included time averaging for phiHydLow, be aware of the drift!
1699    o depth-dependent computation of Bo_surf for pressure coordinates
1700      in the ocean (buoyancyRelation='OCEANICP')
1701      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1702        Theta, Salinity, and Pressure in the parameter list. This routine is
1703        presently contained in find_rho.F. This routine does not give the
1704        correct density for 'POLY3', which would be a z-dependent reference
1705        density.
1706    o cleaned up find_rho
1707      - removed obsolete 'eqn' from the parameter list.
1708    o added two new verification experiments: gop and goz
1709      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1710    checkpoint46g_pre
1711    
1712    checkpoint46f_post
1713    o Enable tangent linear (forward mode) gradient checks:
1714      - extended active file handling to g_... files
1715      - added TANGENT_SIMULATION to theSimulationMode
1716      - extended grdchk package accordingly
1717    o added tangent linear setup in verification/carbon/code_ftl
1718    o added adjoint setup in verification/front_relax/code_ad
1719    
1720    checkpoint46e_post
1721    o Added new equation of state -> MDJWF
1722      - EOS of McDougall et al., 2002, JAOT, submitted
1723      - caveat: the equation of state is only valid for a smaller (more
1724        realistic?) range of values than JMD95P/Z and UNESCO
1725      - added masks to the calculation of pressure in store_pressure
1726      - added more check values for density in check_eos (ini_eos.F), some of
1727        the old check values are out of the range of the MDJWF-eos, so don't
1728        expect perfect matches for those
1729    checkpoint46e_pre
1730    
1731    checkpoint46d_post
1732    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1733      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1734      case of pressure coordinates. eosType='JMD95Z' in
1735      combination with buoyancyRelation='OCEANICP' now causes an error.
1736    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1737      in find_alpha/beta.
1738    checkpoint46d_pre
1739    
1740    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1741      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1742    
1743    checkpoint46c_post
1744    o Changes necessary for ocean in p-coordinates
1745     -  Added new buoyancy relation = 'OCEANICP'
1746     -  Added new parameters = gravitySign (this used to be contained inside
1747        the factor dRdZ which I added when we first switched to R coordinates).
1748     X GM/Redi is not compatible (yet)
1749     X bottom drag and no-slip need to be debugged.
1750    checkpoint46c_pre
1751    
1752    checkpoint46b_post
1753    o Added new equation of state -> JMD95Z and JMD95P
1754      - EOS of Jackett and McDougall, 1995, JAOT
1755      - moved all EOS parameters into EOS.h
1756      - new routines ini_eos.F, store_pressure.F
1757    o Added UNESCO EOS, but not recommended because it requires
1758      in-situ temperature (see JMD95)
1759    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1760      unesco.f to be used with POLY3
1761    checkpoint46b_pre
1762    
1763    checkpoint46a_post
1764    o Added (atmospheric) pressure loading
1765      - new field in FFIELDS.h, etc...
1766      - new cpp flag ATMOSPHERIC_LOADING
1767    o Changed hFacC to _hFacC in calc_phi_hyd.F
1768    o Added SHORTWAVE_HEATING to some files for consistency
1769    checkpoint46a_pre
1770    
1771    checkpoint46
1772    further merges from release1_p5
1773    o new ctrl package
1774      - adopted from ECCO environment to enable optimization
1775      - added Eliassen Palm fluxes to controls
1776    o added Eliassen Palm flux controls to gradient check package
1777    o cost package
1778      - Compatible with new ctrl package
1779      - added Eliassen Palm cost hooks
1780      - modif's of existing cost functions
1781    o Adjoint-related bug fixes in kpp:
1782      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1783      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1784    o autodiff package
1785      - flow directives:
1786        + new for S/R do_the_model_io
1787        + enhanced for S/R checkpoint
1788        + new gmredi.flow
1789      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1790        disable adcommon.h/g_common.h by default.
1791      - fixed problem for adjoint of global_max
1792    o modified verification/carbon/

1796    o incorporated hooks for sponge layer code (external_forcing.F)
1797    
1798    checkpoint45d_post
1799    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1800    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1801      (affects plume_on_slope "cg2d" output)
1802    o add new parameter deltaTfreesurf for free-surface time stepping
1803    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1804    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1805    o change phiMin in exp1 (to agree with documentation)
1806    o add new flags:
1807     - T,S forcing inside/outside Adams-Bashforth
1808     - turn off temp,salt advection and/or forcing
1809     - for each tracer, define internal flag for multiDimAdvection & A-B
1810    o monitor: change definition of KE to check conservation of Energy
1811    
1812    checkpoint45c_post
1813    o Removed f90 comments ("!")
1814    o Modified initialisations to enable exf package for MITgcm
1815      (without invoking ECCO_PACKAGE).
1816    o modifications to gradient check package (Martin Losch)
1817      - enable centered differences
1818      - modified format of standard output
1819    
1820    checkpoint45b_post
1821    o cleaned exchange calls in cg2d
1822    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1823    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1824      to configure barotropic setup (Martin Losch)
1825    o moved some initialisations within bi,bj loop in dynamics
1826      (TAF flow dependency)
1827    o in initialise_varia, moved call packages_init_variables
1828      before convective_adjustment_init
1829      (corresponding adjustment of TAF tape initialisation).
1830    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1831    
1832    checkpoint45a_post
1833    o compute Rho over the whole domain (extend iMin,jMin indices)
1834    o specific exchange for X-slice domain (case Ny=1)
1835    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1836    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1837    
1838    checkpoint44h_post = checkpoint45
1839    o Fix to restore differentiability:
1840      place at which packages_init_variables is called in
1841      initialise_varia is crucial for reverse control flow.
1842    o modifications in GMRedi to enable stable adjoint
1843      (corresponding modif's in thermodynamics, dynamics)
1844    o added missing hook for sponge layer code in external_forcing

1850    o modified carbon verif.
1851    
1852    checkpoint44h_pre
1853    o vertical grid option: allow to put the Interface at the middle between
1854      2 cell-centers ; replace delZ in pkg/kpp by drF.
1855    o GM Advective form: Tracers are advected using the residual transport (=
1856      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1857    
1858    checkpoint44g_post
1859    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1860      results) ; ifdef missing in thermodynamics.F
1861    
1862    checkpoint44f_pre,checkpoint44f_post
1863    o added PTRACERS package
1864      This allows an arbitrary number of passive tracers to be integrated
1865      forward simultaneously with the dynamicaly model.
1866      + Implemented so far:
1867        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1868        - I/O and checkpointing
1869        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1870      + Not implemented so far:
1871        - KPP
1872        - OBCS
1873      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1874        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1875        line in data.pkg.
1876      + This package is disabled by default since it increases storage.
1877    
1878    
1879    o testscript: added -cleanup option
1880    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1881                 b) enable to filter 2D fields.

1883    checkpoint44e_pre,post
1884    o re-wrote convective adjustment to use pre-calculated weights
1885      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1886      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1887      Original calls to convect() still in place.
1888    
1889    chkpt44d_pre,post
1890    o added missing EXCLUDE_MONITOR flags
1891    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1892      (incompatible typ in MIN/MAX expressions caused problems
1893      on IBM SP3)
1894    o in genmake added variable MAKEDEPEND
1895      plus resetting for case SunOS
1896    o added timer_stats.c routine for IBM SP3
1897    o removed variables in dynamics

1917                   added directive for divided adjoint in the_main_loop
1918      - pkg/mdsio: added mdsio_gl_slice
1919

1966    o fixed conditionals for fixed flow/passive tracer only mode
1967    o added tension/strain form of stress tensor
1968    o changes to commenting of arguments for TAF/TAMC
1969    o added/updated many matlab scripts
1970    o added multi-dimensional advection method for tracers
1971      
1972    checkpoint40pre8
1973    o new package rw/
1974      Added method for dumping intermediate local arrays:
1975      mdsio_writetile - same as mdsio_writefield except works from inside
1976                        bi,bj loop
1977      mdsio_writelocal - same as mdsio_writetile except works for local
1978                         arrays
1979      write_local_r? - higher-level wrapper for mdsio_writelocal
1980      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1981      Example given at end of mom_vecinv.F that dumps some local arrays.
1982    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1983      control flux-form versus vector invariant code.
1984      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1985      or genmake -DISABLE ...
1986    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1987      (additional storing is now needed for case vecinv;
1988      currently nothing implemented to switch this storing off
1989      in case fluxform is used since no CPP flag available).
1990    
1991    checkpoint40pre7
1992    o bug fix in dynamics.F
1993      calc_viscosity called before k=1,Nr loop.
1994    o added some #ifdef's ALLOW_PASSIVE_TRACER
1995    o cleaned initialisations in ctrl_map_ini
1996      related to TAF
1997    
1998    checkpoint40pre6
1999    o split dynamics into thermodynamics & dynamics
2000    o corresponding split of calc_diffusivity into
2001      calc_diffusivity, calc_viscosity
2002      (kpp_calc_diff, kpp_calc_visc).
2003    o Added diffkr, kapgm to control variables
2004    o bug fix in gmredi_slope_limit for ldd97
2005    
2006    checkpoint40pre5
2007    o proper initialization of Adams-Bashforth time stepping
2008      + uses forward step for very first step of model (iter=0)
2009    o re-generated *all* output since almost all output is modified by this
2010      change (sorry but we've been putting this one off for about 2 years)
2011      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
2012        *not* regenerated since they are already out of date and I don't
2013        want to create the impression that they are suddenly working.
2014    o removed KAP stuff for DEC's
2015    o modified/added many .cvsignore files in */code and */input
2016    o added new expt "solid-body.cs-32x32x1"
2017      + this uses an alternative form of ini_curvilinear_grid.F which
2018        is not necessarily any better than the current one...
2019    
2020    checkpoint40pre4
2021    o added re-initialisations of utrans,vtrans,rtrans in
2022      calc_common_factors which are crucial for TAF.
2023    o extended iMin,jMin range for calc_common_factors,
2024      calc_diffusivity
2025    o added option ALLOW_PASSIVE_TRACER
2026    o a few minor updates and fixes
2027    
2028    checkpoint40pre3
2029    o created calc_gtr1.F for gad package
2030    o split the_main_loop and re-introduced forward_step
2031    o some recomputations of nIter0 for TAMC
2032    
2033  checkpoint40pre2  checkpoint40pre2
2034  o Updated to latest branch of AJA, JMC  o Updated to latest branch of AJA, JMC
2035  o Added gradient check package  o Added gradient check package
