4      ==============================      ==============================
5    
6    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
7      (not yet implemented for implicit vertical diffusion & advection)
8    o OBCS: extend application of tracer open boundary conditions
9      to a strip beyond the boundary of width Olx/Oly
10    
11    checkpoint56c_post
12    o OBCS as control variables
13      - update ctrl_ad_diff.list, obcs_ad_diff.list
14      - remove balance of obcs controls from default
15      - fix index bug nobcs in ctrl_init
16      - fix dummy fields filen in ctrl_pack
17      - add dummy weights for obcs
18    o lsopt: comment out fort.94 output
19    o optim:
20      - remove unnecessary header files
21      - adjusted namelists
22      - add xerbla.F to Makefile
23    o exf:
24      - multiple modifications of exf_check_range
25      - unit change in exf_init_runoff from [m/year] to [m/s]
26    o mdsio:
27      - i/o-vector change debugLevel from debLevA to debLevB
28    
29    checkpoint56b_post
30    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
31      is called from DO_THE_MODEL_IO
32      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
33      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
34      - clean up PTRACERS_WRITE_TIMEAVE a little
35    o add another verification experiment that tests both the cfc-pkg and
36      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
37      reactive tendencies treated inline with regular timestepping
38    o testreport previously did a lousy job of comparing small numbers, so
39      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
40      implemented in the little c-progam tmp_cmpnum.c which is embedded in
41      testreport.
42    o ptracers_monitor: bug fix for MPI
43    
44    checkpoint56a_post
45    o GCHEM: finish reorganizating the package
46      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
47        (introduces another 3D-array for each passive tracer, but only if
48        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
49        gchemTendency is not needed because the timestep is done separately)
50      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
51      - GCHEM is now---more or less cleanly---separate from PTRACERS
52      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
53        so clear to me how that should be done in a general way.
54    o CFC: improve formatting of output in CFC_ATMOS
55    o PTRACERS:
56      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
57        that ALL experiments with ptracers enable can be checked. This makes
58        GCHEM_MONITOR obsolete.
59      - include a runtime parameter PTRACERS_monitorFreq that defaults to
60        monitorFreq
61      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
62    o add PTRACERS (PTR0[1-5]) to testreport output
63    o exf_check_range:
64      * default changed to .TRUE.
65      * will check values for niter0 if debLevA, every timestep if debLevB
66      * STOP in exf_check_range if 'out of range'
67      * range chosen generous to allow for potential extema
68      TBD: a version with stricter range
69           permitted range would be runtime parameters
70    o GMredi:
71      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
72      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
73      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
74    o GCHEM:
75      - move call to GCHEM_FORCING_SEP, so that it is now called before
76        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
77      - introduced a useGCHEM runtime flag and applied it everywhere.
78      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
79        this flag is now only visible within GCHEM-pkg routines.
80      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
81        be replaced by a 3D array that is computed before thermodynamics; for
82        this, the tracer ID iTracer had to be included into the parameter list
83        of ptracers_forcing
84      - set up forward_step to call gchem_forcing, that will replace
85        gchem_forcing_int in ptracers_forcing
86      - cleaning up
87    o small cleaning of exch2: remove files that are also in eesupp/src
88    
89    checkpoint56
90    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
91    o mnc: cleanup "full" files--fixes out-of-memory problem
92    o ECCO-GODAE
93      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
94      * fully merged and updated from SIO code
95        windstress sign change affects
96        - exf_inscal_[u/v]stress
97        - sign of xx_tau[u/v] adjustments
98        - signs in cost_scat
99      * ctrl_get_gen: avoid update of tau[u/v] for first few days
100      * natl_box_adjoint updated and compressed
101      * 2-level checkpoint switch added
102        (tested in EXP. 1 of natl_box_adjoint)
103      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
104    o SVD
105      * first complete, non-hacked version for SVD calculations
106      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
107        performed via direct access files admtlm_vector.it????
108        (via ctrl_[un]pack)
109      * optimcycle is used for ARPACK iteration counter
110        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
111      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
112        and add linear transforms where necessary
113      * controls are initial/final SST, SSS (can be extended; need to check
114        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
115    o mdsio: filename info to both stderr, stdout
116    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
117      from sign change
118    
119    checkpoint55j_post
120    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
121      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
122    o add consistent build directories and .cvsignore files to verification
123    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
124    o make all subroutines 30 or less characters in length for certain older
125      compilers to work (a thorough search only turns up two routines in
126      pkg/ptracers)
127    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
128      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
129    
130    checkpoint55i_post
131    o change arrays for total vertical diffusivity (2.D if explicit,
132      3.D if implicit) ; each ptracer uses its own background value.
133    o added mnc/NetCDF output capability to ocn_compon_interf
134      - added bits to verification/cpl_aim+ocn so that it can run on
135        ITRDA and other clusters without the mpirun "-wd" option
136    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
137      configuration
138    o give MNC the ability to create additional files rather than
139      exceeding a specified file size limit "MNC_MAX_FILESIZE"
140      - the default is just less than 2GB which is a practical limit
141        on many systems
142    o Compute the non-local term using either KPP vertical diffusivity (=default)
143       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
144    
145    checkpoint55h_post
146    o add verification test "vermix"
147    o remove all the *_ioinc flags and replace with the single global
148      outputTypesInclusive flag
149    o allow to set a vertical profile of vertical diffusivity for T & S
150    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
151    o useMNC moved from data.mnc to data.pkg
152    
153    checkpoint55g_post
154    o Renaming carbon AD experiments to comply with testreport conventions
155    o Updating adjoint of Held-Suarez hs94.1x64x5
156    o Fixing directives for non-ECCO forward_step, after ECCO directives
157      have been fixed to avoid recomp. of do_oceanic_phys
158      Works well for global_ocean.90x40x15,
159      but recomp. issue remains for carbon
160    o Updating adjoint output for natl_box_adjoint after
161      pkg/ecco has been modified (see taga c55d_post)
162    
163    checkpoint55f_post
164    o rename to timeave_init_fixed
165    
166    checkpoint55e_post
167    o some delicate re-shuffle of store directives to avoid one
168      extra call of do_oceanic_physics
169      affects ecco_the_main_loop.F, do_oceanic_physics.F
170      checkpoint_lev1_directives.h
171    o NB: this may break global_ocean adjoint temporarily,
172      but it is clear how to fix it. Will do later, need this now.
173    
174    checkpoint55d_post
175    o ECCO specific cost function terms (up-to-date with 1x1 runs)
176    o ecco_cost_weights is modified to 1x1 runs
177    o modifs to allow observations to be read in as
178      single file or yearly files
179    o enable to read exf forcing fields as either
180      single file or yearly files (flag useExfYearlyFields)
181    checkpoint55d_pre
182    
183    o switch between 2-level and 3-level checkpointing
184    o add ability of MNC to write local and "partial" (eg. 2D slices where
185      the full 3D field is never actually stored) arrays to NetCDF files
186      with the correct (that is, the complete multi-dimensional) set of
187      array indicies
188      - used in mom_vecinv() to write the diagFreq output
189      - tested (demonstrated) in verification/aim.5l_cs
190    o further mnc-ification
191      - add verification/lab_sea to the list with mnc setups
192      - fix undefined mnc v-names in cd_code
193      - add kpp to mnc output (both snapshot and timeave)
194    o non-hydrostatic code
195      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
196        in calc_gw.F
197      - defaults to viscAh
198      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
199        friction or Leith) in non-hydrostatic mode, as long as there is
200        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
201    o pkg/cost
202      extend simple cost functions to treat time mean quantities
203      (T,U,V) via cost_accumulate_state from cost_tile
204    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
205        be 2 times larger than the minimum size the advection scheme requires.
206        now get a perfect conservation of salt in advect_cs test-exp (updated)
207    o GGL90 (Gaspar's TKE mixed layer)
208      - add horizontal diffusion of TKE, requires exchanges in
209        do_fields_blocking_exchanges, horizontal diffusivity is zero by
210        default. In OPA there is no horizontal diffusion of TKE but the
211        mixing coefficients are computed from a horizontal average of TKE of
212        6 points or so. I think that diffusion has a little more physical
213        justification.
214      - clean up ggl90_calc in the hope of reducing memory usage (this hope
215        was in vain)
216      - mask tke-variable in ggl90_init
217    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
218    o fix biharmonic diffusion on CS-grid.
219    o more obcs stuff
220      - added obcs_external_fields_load as an alternative to the EXF-pkg option
221        for reading boundary values. This routine is called from
222        obcs_prescribe_read
223      - updated obcs_check
224      - changed sponge layer relaxation parameter units for days to seconds
225      - turned off sponge layer by default
226      - changed argument list of OBCS_CALC to myTime+deltaTclock
227      - fixed about 35 bugs in obcs_external_fields_load
228    
229    checkpoint55c_post
230    o obcs stuff
231      - new runtime flags useOBCSprescribe, useOBCSbalance
232      - re-arranged obcs_calc
233      - moved exf_getobcs to obcs_prescibe_read
234        obcs_prescibe_read is called after ORLANSKI stuff
235        and independent of it (executable can contain all).
236      - updated obcs_check
237      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
238        These may be necessary only if tangential velocities are
239        prescribed at OB, not sure, needs testing.
240    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
241      which simplifies the calls and passes the ifc check-bounds test
242    
243    checkpoint55b_post
244    o add a 2D scalar, Z location, exchange_2 routine.
245    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
246      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
247      affects advect_cs results (for the wrong reason): update output.txt
248    o use a more standard discretization for biharmonic viscosity ;
249     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
250      affects results of dome set-up: update output.txt
251    o fix gad_advection.F (CubedSphere part), back to version 1.23
252    o fix bug in mom_vi_del2uv.F (CubedSphere part).
253    
254    checkpoint55a_post
255    o merged code to
256      * prescribe/read time-dependent open boundaries
257        (works in conjunction with exf, cal)
258      * sponge layer code for open boundaries
259      * each boundary N/S/E/W now has its own CPP option
260        (healthy for the adjoint)
261    
262    checkpoint55
263    o up-to-date adjoint of previous breaks
264      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
265      - global_ocean_ebm: adjoint still needs fix (TLM ok)
266      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
267      - carbon: * remove tr1-related adjoint verification
268                * add ptracer as control variable
269    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
270      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
271    
272    checkpoint54f_post
273    o in verification/carbin/ remove experiment related to
274      ALLOW_PASSIVE_TRACER (array tr1 etc)
275      code_ad/ input_ad/ results_ad
276    
277    o add two new packages
278      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
279        + subject to optimization (memory)
280      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
281        + subject to reordering (many GOTOs in the original code)
282        + so far opps is called for every (i,j) point, and then operates in
283          the vertical; one may want to reorder the scheme in order operate in
284          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
285          fields)
286    o overhaul of IO so that we now have flags for MDSIO and/or MNC
287      - all verification tests compile and run with linux_ia32_g77
288      - defaults are compatible with current input files--nothing
289        should change if you were not previously using MNC
290      - MNC output has been added in numerous places (eg. timeave)
291        but there are still a few writes not yet do-able with MNC
292        (this is in progress)
293      - flags now allow for either/or/both use of MDSIO and MNC and
294        documentation will soon follow
295      - numerous small formatting cleanups for ProTeX
296    o add version info (via BUILD_INFO.h) to MNC and stdout
297    
298    checkpoint54e_post
299    o add two new packages
300      - pp81 (Packanowski and Philander, 1981), Richardson number and
301        stratification dependent mixing
302      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
303      - these scheme operate in a similar manner as KPP (without ghat, of
304        course), however there is only one diffusivity that is used for both
305        temperature and salinity (and passive tracers)ç
306    o add offline package
307    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
308      provided by Stephanie Dutkiewicz
309    o genmake2: add ability to search for C compilers and cleanup test output
310      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
311    
312    checkpoint54d_post
313    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
314    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
315      leading to additional shift by 5 days each year of integration
316       (i.e. leading to considerable offset over the years)
317    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
318    o start with no AB and no initial filtering (staggerTimeStep):
319      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
320    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
321      (external loading & cpl import/export stay in forward_step.F)
322    o update coupling interface to work with new staggerTimeStep
323    o change MDSIO ptracers_pickup.
324    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
325    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
326    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
327    
328    checkpoint54c_post
329    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
330      this affects (truncation error) output.txt of test-exp:
331       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
332    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
333    o change Qnet to always be the net heat flux, (+upward).
334      affects (truncation error) output of natl_box exp.: updated
335    o define the max number of passive tracers in PTRACERS_SIZE.h
336    o start to test mnc routinely in exp0
337    o add sea-ice loading (sIceLoad) as a new forcing field.
338    
339    checkpoint54b_post
340    o add testreport "-j JOBS" option for parallel builds (tested and pretty
341       impressive on Altix and Opteron systems)
342    o diagnostics can now write NetCDF files through the mnc package
343    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
344    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
345    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
346      affects (truncation error) output of lab_sea & natl_box exp.: updated
347    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
348    
349    checkpoint54a_post
350    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
351    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
352    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
353    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
354      + internal_wave (shift in writing cg2d_ini_res)
355    checkpoint54a_pre
356    
357    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
358      - modified verification/lab_sea and natl_box_adjoint accordingly
359    
360    checkpoint54
361    checkpoint53g_post
362    o prepare splitting of thermodynamics: store convect.counter in common block
363    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
364      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
365    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
366    o new parameter "nShapS": allow to treat differently S from T (nShapT)
367    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
368    o restore adjointability
369    
370    checkpoint53f_post
371    o modifications that affect AIM experiment results (update output.txt):
372      - no advection of S at top interface Nr (pkg/generic_advdiff)
373      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
374    o AIM pkg:
375      - include stability function into surf.Flux derivative relative to Tsurf
376      - calculate clear-sky radiation & surface temp. change (for diagnostics)
377    
378    checkpoint53e_post
379    o merged cylindrical coord configuration
380    o added rotating_tank experiment
381    checkpoint53e_pre
382    
383    checkpoint53d_post
384    o faulks upgraded: re-generate output.txt that have changed:
385       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
386    o Added Bryan and Lewis, 1979, vertical diffusivity profile
387    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
388    o added Sadourny discretization of Coriolis
389      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
390      - re-enabled use of omega3 (useAbsVorticity)
391    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
392      vector-invariant equations
393      - note: does *NOT* yet use same variable visc. for no-slip BC's.
394    o recoded the lateral boundary conditions for non-hydrostatic w, this time
395      hopefully without new bugs
396      - still to do: biharmonic friction for non-hydrostatic w
397    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
398    o regenerated output for global_ocean_ebm (using -ieee)
399    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
400      of mom_common/
401      - simple re-arrangement of instructions within computing loop
402    checkpoint53d_pre
403    
404    checkpoint53c_post
405    o new version of coupler for AIM+thSIce and Ocean models
406     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
407     - land: change Evaporation of snow
408     - aim with thSIce: fix bug in snow-precip.
409    o changes to calc_gw.F
410     - bug fix for w^2 term near the bottom boundary
411     - (hopefully) improve the lateral slip boundary condtions for use with
412        partial/looped cells
413      - because the bug fix changes two verification experiments anyway (exp5
414        and plume on slope), change the lateral boundary condition from half slip
415        to the value of no_slip_sides
416    o ebm package wasnt quite up to the parallel task. Fixed that.
417    o Adjoint of EBM package + verification
418      * TLM OK
419      * ADM not sufficient accuracy yet (needs further testing)
420    
421    checkpoint53b_post
422    o Commiting new energy balance model to repository
423      * package is pkg/ebm
424      * verif. is verification/global_ocean_ebm
425      * references are in ebm_driver.F
426    C      * X. Wang, P. Stone and J. Marotzke, 1999:
427    C        Global thermohaline circulation. Part I:
428    C        Sensitivity to atmospheric moisture transport.

434    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
435    C        Destabilization of the thermohaline circulation
436    C        by atmospheric eddy transports.
437    C        J. Climate 7(12), 1870-1882
438    o Will need long integration testing.
439    checkpoint53b_pre
440    
441    o created pkg/mom_common in preparation for variable viscosity code
442    o renamed and split ini_mnc_io
443    o pkg/land: only liquid water can diffuse or run-off
444    o AIM using land: soil wetness availability account for snow
445    o added printMapIncludesZeros to EEPARMS namelist
446    
447    checkpoint53a_post
448    o restore TAMC compatiility for exf_constants.h
449      (no usage of _d in .h)
450    o Additional storing in KPP in an attempt to fix
451      TAMC problem with adjoint of KPP code.
452      (no success...)
453      Identical code works fine with TAF.
454    o Fixed verification/natl_box_adjoint experiments.
455      Initial conditions for Experiments 4 and 5 are now
456      set to "SEAICE_initialHEFF=0", which is more reasonable,
457      and hence gives results closer to that of Experiment 2.
458      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
459    
460    checkpoint53
461    o stable checkpoint with up to date adjoint
462      TLM tests only run for 1st grdchk at the moment. Its unclear if
463      this is a code problem or a problem with resetting code for g_
464      variables that is being autogenerated wrong.
465      Otherwise:
466       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
467       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
468         are both still in chaos following their security messes.
469    
470    checkpoint52n_post
471    o various build (mostly genmake2) changes including:
472      - ability to build/run more easily within Cygwin and MacOS X
473      - more complicated Makefiles with a stronger dependence on Gnu Make
474    o pkg/seaice modifications
475      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
476        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
477        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
478      - changed proxy for geostrophic velocity and updated
479        verification/lab_sea/results/* accordingly
480      - removed ADI dynamic solver from pkg/seaice
481      - replaced all occurrences of 1/CSTICE or 1/CSUICE
482        they caused a segmentation fault under certain circumstances
483      - removed unused field WATR
484    o bug fix in exf-package:
485      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
486         now reflect that.
487    o small fixes in the cal-package:
488      - set reference date to first of January for the 'model'-calendar
489      - failing of cal_CheckDate in cal_FullDate now actually results in a
490        warning
491    o small modifications in exf-package to increase flexibility:
492      - change climtempfreeze from a constant to a runtime parameter that
493        is specified in data.exf_clim (default = -1.9)
494      - introduce runtime parameter windstressmax (default = 2.0) that is
495        specified in data.exf
496    o fix in pkg/thsice:
497      - update Evap (Tsf changes) to be consistent with Latent heat flux
498      - maintain snow precipitation unchanged (even if Tsf >=0).
499     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
500    
501    checkpoint52m_post
502    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
503      this does not change any of the results, because myIter=0 in swfrac always
504      lead to jwtype=2 (the default anyway), but the call makes little sense
505      as a default
506    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
507    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
508      atmospheric model (AIM) to use it ; add a "slab ocean" component.
509    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
510    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
511    o extending useSingleCpuIO option to work with new exch2 I/O format
512      - old-style, missing-tile I/O is still accessible by defining CPP
513        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
514    o monitor package can write to NetCDF files and/or STDOUT
515    o fix re-definition bug in MNC_GRID_INIT_ALL()
516    o doc/api_reference added
517      - a framework for building an API Reference Manual using all
518        the "protex" comments embedded in the code
519      - see pkg/generic_advdiff, pkg/mnc for examples
520    o MNC:
521      - make myThid the last argument for all subroutines
522      - new default for the grid files: NO halos
523      - add useMNC and other run-time flags
524      - separate per-file-group handling of the unlimited dimension
525      - early initialization of MNC w/ flags read at the eeboot stage
526        and lookup tables set in initialize_fixed
527      - write all MNC output to a freshly-created directory
528    o thermodynamics sea-ice (thsice) is now tested with testreport.
529    o test exp. advect_cs: use the standard cs32 grid ; update output.
530    o Added functionality to grdchk:
531      pick global i,j,k position (or nearest wet) where to perform check.
532    
533    checkpoint52l_post
534    o new land formulation:
535      a) use ground enthalpy as prognostic variable to ensure exact
536         energy conservation.
537      b) account for water temperature and for latent heat of freezing
538         in all processes (rain, run-off, ground storage)
539      c) compute surface and ground temperature implicitly.
540    o aim_v23 modification for new land model:
541      a) Treat separately land / ocean / sea-ice surface fluxes
542         to allow implicit computation of land & sea-ice surface temp.
543      b) add snow precipitation.
544    checkpoint52l_pre
545    
546    o fix problem (when 1 tile is empty) in min/max monitor.
547    o fix bug in timeAve (u,vZetatave in common block)
548    o no restoring terms under ice for pkg/seaice
549    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
550    o bug fix for pkg/seaice pickups
551    o change MNC call locations and add coordinate attributes
552    o mask vorticity at the corner ; affects global_ocean.cs output
553    o fix ini_curvilinear_grid ; test CS experiments with mpi
554    o aim.5l_cs: modify sea-ice fraction input file ; update output
555    o exf: Adding simple range check routine for exf fields after read
556    
557    checkpoint52k_post
558    o removed top-level directory "diags"
559      - we migrated these functions to pkg/timeave a long time ago
560    o fixed bug introduced in pkg/monitor
561    o accuracy ctrlprec = 32 insuffient for gradient checks using
562      averaged fields (I/O via cost_averages)
563      -> use ctrl.h in active_file*.F to control I/O precision.
564    o paramter list of CALL ADTHE_MAIN_LOOP
565    o added initial do_the_model_io to ecco
566    o set all ...Freq to zero after cost_final
567      taveFreq, dumpFreq, pChkptFreq
568    o MAIN and ECCO differentiability restored
569    
570    checkpoint52j_post
571    o fix nchklev in tamc.h for global_ocean...
572    o Bringing flow and store directives up-to-date
573    o Really weird thing!
574      call do_the_model_io from the_main_loop with parameters
575      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
576      TAF places a faulty re-call of initialise_varia
577      after cost_final call which should not be there!
578    checkpoint52j_pre
579    
580    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
581      error messages
582    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
583    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
584      debug output
585    o modfied mdsio_writefield.F to handle non-global files under exch2
586    o update AIM Cubed-Sphere exp (aim.5l_cs):
587      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
588    o update AIM Equatorial Channel exp:
589      use standard aim_v23 pkg and change the SST fields to be more realistic.
590    o globalFile now works with exch2
591    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
592      mon_vort3.F to make exch2 friendly with >1 tile per cube face
593    o limit timeave output for hi-res integrations
594    
595    checkpoint52i_post
596    o removed CPP_EEOPTIONS.h from verification/*/code
597    o updated the tiling for global_ocean_pressure
598    checkpoint52i_pre
599    
600    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
601      the old pkg/aim).
602    
603    checkpoint52h_pre
604    o shortened offending lines in exch2_send_rx?.template
605    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
606    o genmake2: add build & execute test for NetCDF code
607    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
608      old grid files, moved CPP_EEMACROS.h to pkg/exch2
609    o added useSingleCPUIO flag to monitor.F and mon_out.F
610    o added temporary hack for sea-ice dynamics on the cube:
611      metric terms are ignored and it is assumed that
612      there is no sea-ice on cube faces 1, 2, 4, and 5.
613    
614    checkpoint52f_post
615    o added exch2 cube routines to pkg/exch2
616    o modified hs94.cs-32x32x5 to use it
617    o added new grid files to hs94.cs-32x32x5
618    checkpoint52f_pre
619    
620    checkpoint52e_post
621    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
622      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
623    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
624      to work with implicit vertical advection and AB ;
625    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
626    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
627     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
628    checkpoint52e_pre
629    
630    o fix bug in impldiff when Nr=1 or Nr=2.
631    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
632    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
633    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
634      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
635    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
636    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
637    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
638    
639    checkpoint52d_post
640    o re-tiled many expts to allow comparison in multi-processor mode
641      - updated output accordingly
642      - changed hs94.128x64x5 to use intial T from file rather than use the
643        random number generator
644    o add infrastructure in model routines for fizhi and gridalt packages
645    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
646    o changes to permit hi-res, cubed-sphere, configuration
647      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
648      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
649      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
650        of surface winds for the cube
651      (A verification experiment, based on global_ocean.cs32x15, but with
652       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
653       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
654       complete with example surface forcing files and matlab scripts to look
655       at the output and compare it with that of global_ocean.cs32x15.)
656    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
657       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
658       to conform to the common rule.
659    o check-in the first version of the coupler + interfaces for multi-components
660       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
661       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
662       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
663       - ocean and atmos. share the same horizontal grid (no interpolation).
664       - exchanges between component and coupler is done in forward_step
665    o new verification experiment, cpl_aim+ocn:
666       coupled ocean - AIM atmosphere on cs32 grid.
667    
668    checkpoint52d_pre
669    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
670    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
671    
672    checkpoint52c_post
673    o Fixing OPTIONS files for use of exf:
674      - ALLOW_ECCO not needed
675      - ECCO_CPPOPTIONS.h should not be included from
676        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
677        as has been the case in the past
678      - All cal/exf related options are currently set in
679        single header file. Should remain so until we
680        agree on a consistent new policy.
681    o Removed all CPP options for cal package.
682      cal has no more CPP options.
683    o modified STOREs in GAD_ADVECTION
684    o corrected key comp. for passkey
685    
686    checkpoint52b_post
687    o new version: "thsice" of thermodynamic sea-ice pkg:
688     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
689     - modify fluxes but do not change theta directly;
690     - light cleaning of bulk_force pkg (still needed with thsice).
691     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
692       + output_thsice.txt to test thsice & bulk_force pkgs.
693    o put back grid & coriolis monitor output.
694    checkpoint52b_pre
695    
696    o call "do_the_model_io" at the beginning (=> dump initial state)
697    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
698    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
699      (need info on NUMBER_OF_PTRACERS)
700    o missing PTRACERS headers in some routines
701    o default tamc.h in pkg/autodiff supposed to crash
702      to ensure proper customization
703    
704    checkpoint52a_post
705    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
706      - moved surfaceTendencyTice from pkg/seaice to main code
707      - subroutine FREEZE_SURFACE now limits only surface temperature
708        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
709        => new output.txt for global_ocean.cs32x15 & global_with_exf
710      - keep the old version of FREEZE for backward compatibility;
711        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
712      - corresponding modifs for TAF directives
713    o added surface flux output variables to TIMEAVE_STATVARS
714    o time-averaged output for pkg/ptracers
715    o fix problem with ECCO-related divided adjoint
716      snapshot file was missing some ad-variables,
717      but no warning issued by TAF
718    
719    checkpoint52a_pre
720    o some bug fixes for #undef REAL4_IS_SLOW
721    
722    checkpoint52 = ecco_c52_e35
723    o after testing adjoints of checkpoint51u_post
724    
725    checkpoint51u_post
726    o this is the post-merge tag of the ecco-branch
727      (needs another clean checkout and re-testing)
728    o various natl_box_adjoint configs and results
729      but no input fields
730    o obcs adjoint not yet merged!
731    o adding ECCO global 1x1 and 2x2 degree configs
732    o updated/extended some store directives for seaice
733    o pkg/ecco now containes ecco-specific part of cost function
734    o top level routines the_main_loop, forward_step
735      supersede those in model/src/
736      previous input data.cost now in data.ecco
737      (new namelist ecco_cost_nml)
738    o in ctrl/ cleaned some cross-dependencies and updated CPP options
739    
740    checkpoint51t_post
741    o this is the pre-merge tag of the ecco-branch
742    
743    checkpoint51s_post
744    o cleanup: removed various obsolete #define-s
745    o pkg/grdchk
746      - renamed 'ph-grd 3' to 'grad-res'
747      - merged from ecco-branch
748        (remaining bug fixes for obcs gradient checks)
749      - additional high-precision output for testreport
750        (grep for 'precision_grdchk_result')
751    
752    checkpoint51r_post
753    o cleaned up or removed CPP_OPTIONS.h files
754    o updated results for some of the tests to reflect the new
755      optfiles (-ieee: -O0 instead of -O3)
756    
757    checkpoint51q_post
758    o cd_code:
759      - moved cd_scheme.F -> cd_code_scheme.F
760      - separate read_checkpoint from cd_code_ini_vars.F
761      - separated cd_code part from write_checkpoint
762      - updated AD_SOURCE, generated .flow
763      - added CD_CODE_VARS.h to the_main_loop
764      - Moving cd_code specific store dir.s to pkg/cd_code
765    o ctrl package totally restructured
766      - pack/unpack now optional and decoupled from
767        xx_/adxx_ I/O
768      - ctrl_pack/unpack cleaned
769        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
770      - confined inclusion of AD_CONFIG.h to where necessary.
771    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
772    
773    checkpoint51p_post
774    o create initial cd_code package
775      - WARNING: the initialization of fields within packages
776        is broken because INI_FIELDS (where READ_CHECKPOINT is
777        called) is called *before* PACKAGES_INIT_VARIABLES.
778        This seems to be backwards since
779        1) its important to initially zero the entire field including
780           the "halo" region
781        2) zeroing needs to be done *before* reading pickup info
782           and the pickup call might or might not happen in any
783           particular run
784      - this needs an overhaul for R2

913    o Added on-the-fly spatial interpolation capability
914        "USE_EXF_INTERPOLATION" to pkg/exf.
915      - This is a temporary Cartesian-grid hack until
916        the super-duper ESMF coupler becomes available.
917      - See verification/global_with_exf/README for usage example.
918      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid

951      - debLevB: equivalent to current debugMode=.TRUE.
952    o introducing pathname variable mdsioLocalDir for mdsio
953      that can be specified at runtime
954      (relevant for cluster I/O to local disk)
955    `
956    >>>checkpoint51b_post
957    adjoint of ptracers
958    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM

976    
977    checkpoint51
978    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
979      - autodiff, ctrl, exf, grdchk, seaice
980      kept separate packages
981      - cost, ecco, obcs
982    o updating verification/internal_wave, verification/lab_sea
983      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
984    
985    checkpoint50i_post
986    o Preparing next differentiable checkpoint and sync
987      of MAIN vs. ecco-branch
988      - 1st step: this one is differentiable
989      - 2nd step: next(! not this) checkpoint will have updated packages
990                  from ecco-branch)
991    
992    checkpoint50h_post
993    o new package "land": provide surface BC for AIM.
994    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
995    o AIM: use true log-P extrapolation for near surface temp (= as in
996        F.Molteni paper) ; update aim.5l_cs output.
997    o New variable in PARM03 for more flexible pickups
998    o somewhat cleaned package initialisation sequence for
999      ctrl/ cost/ ecco/ in packages_... routines
1000    
1001    checkpoint50g_post
1002    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1003      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1004      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1005        made the default because of faster convergence than ADI
1006    
1007    checkpoint50f_post
1008    o exf totally restructured
1009      - replaced all exf_set_ routines by one generic exf_set_gen.F
1010        and made sure it's still differentiable
1011      - split exf_getffields.F into new exf_bulkformulae.F
1012      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1013      - updated adjoint/makefile and relevant verif. accordingly
1014    
1015    checkpoint50f_pre

1023     o removed lots of single quotes from comments
1024    
1025    checkpoint50e_post
1026    o make KPP work with PTRACERS
1027     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1028       nearly a copy of kpp_transport_s
1029     - there is no analogue to SurfaceTendencyS, so I have to use
1030       gPtr(of the surface layer) instead
1031    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1032    checkpoint50e_pre
1033    
1034    checkpoint50d_post
1035    o change kpp output from multiple-record state files to single-record state
1036      files analogous to write_state.F
1037    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1038      analogous to the cg2d-related output.
1039    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1040      so that writing to internal file fn (with length 512) fails.
1041    checkpoint50d_pre
1042    
1043    checkpoint50c_post
1044    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1045    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1046    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1047    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1048    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1049    
1050    checkpoint50c_pre
1051    Merging from release1_p13:
1052    o bug fix for pkg/seaice dynamic solver
1053    o Added SEAICE_initialHEFF to pkg/seaice
1054    
1055    checkpoint50b_post
1056    o store u*,v* in gU,V instead of in guNm1,gvNm1
1057    o in order to put the momForcing out of the Adams-Bashforth:
1058      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1059      to timestep.F
1060    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1061    o re-generate output for highly sensitive test-exp:
1062       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1063    
1064    checkpoint50b_pre
1065    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1066    o corrected CPP option mismatch in exf_Bulk... functions for case
1067      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1068    
1069    checkpoint50a_post
1070    o Bug fix for merging between c50 and KPP.
1071      ikey was passed from thermodynamics to kpp_calc via
1072      common block rather than being recomputed in kpp_calc,
1073      in contradiction with new key itdkey.
1074      New key ikppkey created, and tamc.h headers updated.
1075    
1076    checkpoint50
1077    - 2nd step of merge with ecco-branch:
1078      merge changes in ecco-branch back into main trunk
1079    - bug fix in find_alpha
1080    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1081    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1082    - merged some sliced AD support routines
1083    
1084    checkpoint49
1085    merged from ecco-branch:
1086    o exf:
1087      - Enable initialisation of forcing fields to constant
1088        (runtime) values.
1089      - in exf_getffields.F
1090        Reduce i-/j-loop to interior domain, discarding overlaps.
1091        That also fixes wrong TAF-key computations for key_1, key_2
1092        with bulf formulae.
1093      - exf_init.F modify #ifdef for exf_init_evap
1094      - exf_getffieldrec.F, ctrl_getrec.F
1095        The following INT-usages are not safe:
1096          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1097          fldcount = int(fldsecs/fldperiod) + 1
1098        and were modified.
1099    o autodiff: checkpoint_lev...
1100      - updated storing for bulk formulae (some arrays were missing)
1101      - added state for seaice package
1102      - synchronized with main branch
1103    o DIVA:
1104      Modif.s in
1105      - the_main_loop.F
1106      - the_model_main.F
1107      and added cost_final_restore.F cost_final_store.F
1108      o With these changes, it is possible to fully separate
1109        the first forward run to compute the cost function (mdthe_main_loop)
1110        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1111        into separate model executions.
1112        This enables better tuning of DIVA to given queue sizes.
1113      o Loss of cost function value in consecutive DIVA runs is
1114        fixed by storing to 'costfinal' file.
1115      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1116        beginning/end of adjoint integration is accounted for.
1117      The current changes apply to TAF-1.4.26.
1118      TAF has one remaining bug, requiring one manual change
1119      (see MITgcm manual).
1120    o cal: synchronized between MAIN and ecco-branch
1121    
1122    checkpoint48i_post
1123    o Changes to restore differentiability of code w.r.t. previous tag
1124      (mostly adding new routines to make list and replacing
1125      pressure by totPhiHyd).
1126    o Updated and merged grdchk package
1127      - has both ADM and TLM checks
1128      - works for single- and multi-proc.
1129      - output cleaned
1130      - worked successfully for parallel DIVA
1131    o genmake:
1132      - Adding -platform=SP4
1133      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1134    o Modif. for DIVA:
1135      ctrl_unpack should not be called in intermediate DIVA interval.
1136      (similar thing would apply for active files such as
1137      tbar, sbar, psbar, which should not be reinitialised;
1138      only relevant for ecco-branch)
1139    
1140    checkpoint48h_post
1141    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1142    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1143    o Added SEAICE_initialHEFF to pkg/seaice
1144    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1145    
1146    checkpoint48g_post
1147    --- EOS:
1148    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1149      store total Potential in totPhyHyd for diagnostics & EOS.
1150    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1151    --- Pressure/geopotential gradient:
1152    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1153    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1154      ( changes results of global_ocean_pressure )
1155    o NLFS + z-coord.: add eta*Rho' contribution.
1156    o accurate phiHyd when using interface-W at the middle between 2 centers
1157     ( changes results of ideal_2D_oce )
1158    o includes r* 2nd term in potential gradient.
1159    
1160    checkpoint48f_post
1161    Merging from release1_p12:

1168      (SBO) core products, including oceanic mass, center-of-mass,
1169      angular, and bottom pressure (see pkg/sbo/README.sbo).
1170    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1171      to avoid negative values in shallow regions.
1172      - updated verification/natl_box/results/output.txt
1173      - updated verification/lab_sea/results/output.txt
1174    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1175    o Added useSingleCpuIO option (see PARAMS.h).
1176    o Updated useSingleCpuIO option in mdsio_writefield.F to
1177      work with multi-field files, e.g., for single-file pickup.
1178    o pkg/seaice:
1179      - bug fix in growth.F: QNET for no shortwave case

1190    o dynamics: change definition of computational domain & adapt mom_fluxform
1191      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1192    o following exp works with Olx=Oly=2 (and pass through checkbounds option):

1198    
1199    checkpoint48d_post
1200    o in preparation for r*:
1201     a) use pre-computed gradient of hydrostatic potential:
1202        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1203     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1204        => affects results of glob_oce_pressure (different truncation error)  
1205      update output.txt of ideal_2D_oce & global_ocean_pressure
1206    
1207    checkpoint48d_pre
1208    o in preparation for r*:
1209      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1210      pass the 2 comp. of the grad. as arguments to momentum S/R.
1211      but for the moment, only used if it does not change the results.
1212    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1213    
1214    checkpoint48c_post
1215    Modifications in treatment of initial flux forcing controls
1216    to avoid extra storing of flux fields.
1217    
1218    checkpoint48c_pre
1219    o Added tidal_basin_2d experiment (currently 1D!)
1220    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1221    
1222    checkpoint48b_post
1223    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1224     (modification to pressure gradient not yet implemented)
1225    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1226      (for U & V) that are used for vertical advection of momentum.
1227    
1228    checkpoint48a_post
1229    o In preparation for r*, use temp. array to compute vertical transport
1230       in flux-form momentum pkg. => change results of few test-exp.
1231      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1232                        lab_sea, natl_box & plume_on_slope
1233    
1234    checkpoint48
1235    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1236    
1237    checkpoint47j_post
1238    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1239    o moved adexch from forward_step to addummy_in_stepping
1240    o added exch in ctrl_map_...
1241    o aveFreq.=0. at end of cost_final to avoid overwrite in
1242      reverse checkpointing loop
1243    o Yet more changes in gmredi:
1244      * adgmredi_calc_tensor
1245        avoiding all recomputation of gmredi_slope_limit
1246      * adgmredi_x/y/rtransport
1247        added flag for excessive storing to avoid recomp. of
1248        u/v/rtans, dTdx/y/z
1249        -> this is not really necessary and very memory-consuming
1250      * adgmredi_slope_psi:
1251        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1252      * gmredi_slope_limit
1253        re-activated full calculation of taperfct for case 'ac02'
1254    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1255    
1256    checkpoint47i_post
1257    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1258    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1259      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1260    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1261    o gmredi: fix few bugs.
1262    
1263    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1264    This will be a good checkpoint to plug into the ecco-branch.
1265    o few modif.'s to get latest version adjointed
1266      (mainly kick out code in ini_linear_phisurf)
1267    o modif's to run adjoint with exactConserv
1268    o case GM_BOLUS_ADVEC should be cleaned
1269      S/R gmredi_slope_psi should be cleaned
1270    o verification/carbon now has exactConserv=.TRUE.
1271    
1272    checkpoint47g_post
1273    o time-average AIM output: becomes independent from statvars time-average
1274      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1275    o After TAF bug fix:
1276      Tested adjoint of gmredi package.
1277      Tests were done with checkpoint47 rather than with latest
1278      checkpoint47f_post since the latter is broken for the adjoint
1279      verification/carbon/ contains both ADM and TLM gradient checks.
1280    Here they are, before they get changed/lost/stolen.
1281    Mostly modif.'s to fix numerical sensitivities.
1282    Gradient checks OK for
1283    - GM_taper_scheme:
1284      * clipping
1285      * ac02
1286      * linear
1287      * glw91
1288      * dm95
1289      * ldd97
1290    - GMREDI_OPTIONS:
1291      * GM_VISBECK_VARIABLE_K
1292      * GM_NON_UNITY_DIAGONAL
1293      * GM_EXTRA_DIAGONAL
1294      * GM_BOLUS_ADVEC
1295    in conjunction with data.gmredi parameters to be checked in
1296    in a few minutes under verification/carbon/code/
1297    
1298    checkpoint47f_post
1299    Merging from release1_p10:
1300    o modifications for using pkg/exf with pkg/seaice
1301      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1302        and SEAICE_EXTERNAL_FLUXES
1303      - pkg/exf CPP options EXF_READ_EVAP and
1304        EXF_NO_BULK_COMPUTATIONS
1305      - usage examples are Experiments 8 and 9 in
1306        verification/lab_sea/README
1307      - verification/lab_sea default experiment now uses
1308        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1309    
1310    checkpoint47e_post
1311    o created a tag prior to creating a branch
1312    
1313    checkpoint47d_post
1314    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1315      at the bottom boundary had an erroneous half slip boundary condition
1316    o added bottom drag and no slip boundary condition capabilities to
1317      oceanic pressure coordinates code
1318    o added new verification experiment global_ocean_pressure, this experiment is
1319      also described in the tutorial section of the manual
1320    checkpoint47d_pre
1321    
1322    checkpoint47c_post
1323    o Added a verification experiment for a global cubed-sphere ocean run
1324      -  verification/global_ocean.cubed32x32x30
1325      -  uses pkg/therm_seaice and pkg/bulk_forcing
1326    
1327    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1328    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1329      when using P-coordinate; only implemented for atmospheric config.
1330    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1331      NOTES: requires option NONLIN_FRSURF to be "#define".
1332    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1333    
1334    checkpoint47b_post
1335    Merging from release1_p9:
1336    o pkg/seaice
1337      - removed GOTO's and added taf directives
1338      - double precision constants to reduce the g77 (Linux)
1339        to F77 (SGI) differences reported in release1_p8
1340    o tools/genmake
1341      - added SGI options
1342    o verification/testscript
1343      - updated to that of checkpoint47a_post
1344    o verification/global_ocean.90x40x15/input/eedata
1345      - modified for SGI f77 compatibility
1346    o verification/lab_sea
1347      - added description of sea-ice model
1348      - added missing matlab routines
1349      - added test of thermodynamics parallelization
1350    
1351    checkpoint47a_post
1352    o new pkg: aim_v23
1353     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1354       for now, keep the same surface forcing as before.
1355     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1356     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1357     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1358    o add diagnostic of surface correction term in monitor output
1359    
1360    o bulk_force and therm_seaice
1361    - Two packages:  bulk_force (Bulk forcing)
1362      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1363    - Earlier integration from Stephaine Dutkiewicz
1364      and Patrick Heimbach.
1365    - Two ifdef statements for compile time,
1366       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1367    
1368    checkpoint47
1369    differentiable version of checkpoint46n_post
1370    o bug fix in quasihydrostaticterms
1371    o * "clean" adjoint code (in terms of extensive recomputations)
1372        can now be obtained for all GMREDI options (i.e. for
1373        - GM_VISBECK_VARIABLE_K
1374        - GM_NON_UNITY_DIAGONAL
1375        - GM_EXTRA_DIAGONAL
1376        - GM_BOLUS_ADVEC )
1377      * However, wrong gradient check problem remains unsolved.
1378      * New CPP options have been introduced for different
1379        tapering schemes
1380    o external_fields_load now part of differentiation list
1381    o pressure needs multiple storing;
1382      would be nice to have store_pressure at beginning or
1383      end of forward_step, e.g. by having phiHyd global (5-dim.)
1384      (NB: pressure is needed for certain cases in find_rho,
1385      which is also invoked through convective_adjustment).
1386    o recomputations in find_rho for cases
1387     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1388    o #define ATMOSPHERIC_LOADING should be differentiable
1389    o ini_forcing shifted to begining of initialise_varia
1390    o Incorporating QNVS line search routines into MITgcm
1391      (this is separate code, and therefore not under pkg)
1392      lsopt/, optim/
1393    o Updated verification/carbon/
1394      - #define GM_VISBECK_VARIABLE_K
1395      - GM_taper_scheme    = 'ldd97'    
1396    
1397    checkpoint46n_post
1398    Merging from release1_p8:
1399    o verification/natl_box:
1400      updating new external_fields_load routine
1401    o New package: pkg/seaice
1402      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1403      The sea-ice code is based on Hibler (1979-1980).
1404      Two sea-ice dynamic solvers, ADI and LSR, are included.
1405      In addition to computing prognostic sea-ice variables and diagnosing
1406      the forcing/external data fields that drive the ocean model,
1407      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1408      The implied surface heat flux is then stored in variable
1409      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1410      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1411      non-local transport term.  Because this call precedes model
1412      thermodynamics, temperature under sea-ice may not be "exactly" at
1413      the freezing point by the time theta is dumped or time-averaged.
1414      N.B.: fairly large differences in accuracy occur across
1415            different platforms/compilers; comparison between
1416            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1417            generated output gives:
1418       T           S           U           V
1419      C D M    c        m  s        m  s        m  s        m  s
1420      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
1421      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
1422      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
1423    
1424      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1425    o GAD:
1426      - generated new common blocks to account for call of
1427        same gad routines with differing traceridentities
1428        (needed to modify tracerIdentity indices in GAD.h)
1429      - generated separate common blocks for case useCubedSphereExchange
1430        (Department of Futurology)
1431      - parameter lists to gmredi_?transport: added tracerIdentity
1432      - added new key indices to tamc.h
1433    o external_fields_load:
1434      - added this routine to TAF list
1435      - needed to make some common blocks global and additional storing
1436        along the same lines as exf package (checkpoint_lev?_directives.h)
1437    o exf:
1438      updated external forcing package
1439      - bug fixes carried over from ecco-branch
1440        (missing OBCS_OPTIONS.h in two routines)
1441      - enable easy to use "no forcing".
1442      - added exf I/O for atmospheric loading
1443      - added exf I/O for runoff data
1444      - transfered scaling between exf <-> MITgcm to exf namelist
1445    o Adding new verification experiment global_with_exf.
1446      This verification experiment is almost identical to the
1447      global_ocean.90x40x15 experiment, except that it uses
1448      the exf (and cal) package instead of the
1449      external_fields_load routine (cf README file).
1450    
1451    checkpoint46m_post
1452    o modified testscript to return -- when there are no lines of "%MON" output
1453    o added new flag "quasiHydrostatic" for QH mode
1454      and new routine quasihydrostaticterms()
1455    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1456      New routine: mom_u_coriolis_nh()
1457    o fixed sign of non-hydrostatic metric terms in u and v equations.
1458      Depend on correct sign of gravitySign.
1459    o added work.pc* to .cvsignore in aim directories using ifc
1460    o introduced flag for controllin non-hydrostatic metric terms
1461    o removed gravitySign from PARM04
1462    o switched to g77/ifc from pgf77 in aim experiments
1463    
1464    checkpoint46l_post
1465    o made convective adjustment work with pressure coordinates:
1466     - changed the direction of k-loop in convective_adjustment.F for the
1467       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1468     - adjusted the reference pressure k-index in convective_adjustment.F
1469     - adjusted the convection condition in convect.F (in analogy to
1470       calc_ivdc.F)
1471     - convective_adjustment no longer computes anything on the halos
1472     - removed the warnings about negative salinity from find_rho.F and
1473       find_alpha.F; instead the new routine look_for_neg_salinity, called
1474       at the beginning of find_rho, find_alpha, and find_beta, does a
1475       check of the entire slice, if CPP-option
1476       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1477    checkpoint46l_pre
1478    
1479    checkpoint46k_post
1480    o fixed the verification/global_ocean.90x40x15 experiment:
1481     - new bathymetry (the world according to A., JMC, and M.)
1482     - new initial fields and forcing fields (*.bin files)
1483     - new POLY3.COEFFS (for the next release one should switch to a full
1484       equation of state: JMD95P or MDJWF)
1485     - fixed several errors and redundancies in the data file
1486     - experiment uses looped cells
1487     - added matlab directory with diagnostic scripts for plotting of output
1488    
1489    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1490     - read AIM physics parameters from a file (data.aimphys)
1491     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1492    
1493    checkpoint46j_post
1494    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1495    o move wVel computation at the end of the time step, in S/R integr_continuity
1496    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1497    o update timeave pkg for wVel diagnostic.
1498    checkpoint46j_pre
1499    
1500    checkpoint46i_post
1501    o Clean up AIM package (and keep the results unchanged):
1502      include CPP_OPTION and use IMPLICT NONE in all routines ;
1503      declare all the variables _RL ; use _d 0 for all numerical constants.
1504      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1505    
1506    checkpoint46h_post
1507    o cleaned up the use of rhoNil and rhoConst.
1508      - rhoNil should only appear in the LINEAR equation of state, everywhere
1509        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1510        and the dynamical equations are all divided by rhoConst
1511    o introduced new parameter rhoConstFresh, a reference density of fresh
1512      water, to remove the fresh water flux's dependence on rhoNil. The default
1513      value is 999.8 kg/m^3
1514    o cleanup up external_forcing.F and external_forcing_surf.F
1515      - can now be used by both OCEANIC and OCEANICP
1516    checkpoint46h_pre
1517    
1518     Added code to convert surface volume flux (fresh water) into
1519     a mass flux when using P coordinates in the ocean (OCEANICP).
1520     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1521    
1522    checkpoint46g_post
1523    o Include a new diagnostic variable phiHydLow for the ocean model
1524      - in z-coordinates, it is the bottom pressure anomaly
1525      - in p-coordinates, it is the sea surface elevation
1526      - in both cases, these variable have global drift, reflecting the mass
1527        drift in z-coordinates and the volume drift in p-coordinates
1528      - included time averaging for phiHydLow, be aware of the drift!
1529    o depth-dependent computation of Bo_surf for pressure coordinates
1530      in the ocean (buoyancyRelation='OCEANICP')
1531      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1532        Theta, Salinity, and Pressure in the parameter list. This routine is
1533        presently contained in find_rho.F. This routine does not give the
1534        correct density for 'POLY3', which would be a z-dependent reference
1535        density.
1536    o cleaned up find_rho
1537      - removed obsolete 'eqn' from the parameter list.
1538    o added two new verification experiments: gop and goz
1539      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1540    checkpoint46g_pre
1541    
1542    checkpoint46f_post
1543    o Enable tangent linear (forward mode) gradient checks:
1544      - extended active file handling to g_... files
1545      - added TANGENT_SIMULATION to theSimulationMode
1546      - extended grdchk package accordingly
1547    o added tangent linear setup in verification/carbon/code_ftl
1548    o added adjoint setup in verification/front_relax/code_ad
1549    
1550    checkpoint46e_post
1551    o Added new equation of state -> MDJWF
1552      - EOS of McDougall et al., 2002, JAOT, submitted
1553      - caveat: the equation of state is only valid for a smaller (more
1554        realistic?) range of values than JMD95P/Z and UNESCO
1555      - added masks to the calculation of pressure in store_pressure
1556      - added more check values for density in check_eos (ini_eos.F), some of
1557        the old check values are out of the range of the MDJWF-eos, so don't
1558        expect perfect matches for those
1559    checkpoint46e_pre
1560    
1561    checkpoint46d_post
1562    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1563      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1564      case of pressure coordinates. eosType='JMD95Z' in
1565      combination with buoyancyRelation='OCEANICP' now causes an error.
1566    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1567      in find_alpha/beta.
1568    checkpoint46d_pre
1569    
1570    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1571      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1572    
1573    checkpoint46c_post
1574    o Changes necessary for ocean in p-coordinates
1575     -  Added new buoyancy relation = 'OCEANICP'
1576     -  Added new parameters = gravitySign (this used to be contained inside

1806                        bi,bj loop
1807      mdsio_writelocal - same as mdsio_writetile except works for local
1808                         arrays
1809      write_local_r? - higher-level wrapper for mdsio_writelocal
1810      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1811      Example given at end of mom_vecinv.F that dumps some local arrays.

1815      or genmake -DISABLE ...
1816    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1817      (additional storing is now needed for case vecinv;
1818      currently nothing implemented to switch this storing off

1837    o proper initialization of Adams-Bashforth time stepping
1838      + uses forward step for very first step of model (iter=0)
1839    o re-generated *all* output since almost all output is modified by this
1840      change (sorry but we've been putting this one off for about 2 years)
1841      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1842        *not* regenerated since they are already out of date and I don't
1843        want to create the impression that they are suddenly working.
1844    o removed KAP stuff for DEC's
1845    o modified/added many .cvsignore files in */code and */input
1846    o added new expt "solid-body.cs-32x32x1"
