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

435    C      * X. Wang, P. Stone and J. Marotzke, 1999:
436    C        Global thermohaline circulation. Part II:
437    C        Sensitivity with interactive transport.

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

918    o Added on-the-fly spatial interpolation capability
919        "USE_EXF_INTERPOLATION" to pkg/exf.
920      - This is a temporary Cartesian-grid hack until
921        the super-duper ESMF coupler becomes available.
922      - See verification/global_with_exf/README for usage example.
923      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
924        flags and modified pkg/seaice accordingly.
925    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
926        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer

956      - debLevB: equivalent to current debugMode=.TRUE.
957    o introducing pathname variable mdsioLocalDir for mdsio
958      that can be specified at runtime
959      (relevant for cluster I/O to local disk)
960    `
961    >>>checkpoint51b_post
962    adjoint of ptracers
963    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
964    o extended state in checkpoint_lev?, etc.

981    
982    checkpoint51
983    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
984      - autodiff, ctrl, exf, grdchk, seaice
985      kept separate packages
986      - cost, ecco, obcs
987    o updating verification/internal_wave, verification/lab_sea
988      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
989    
990    checkpoint50i_post
991    o Preparing next differentiable checkpoint and sync
992      of MAIN vs. ecco-branch
993      - 1st step: this one is differentiable
994      - 2nd step: next(! not this) checkpoint will have updated packages
995                  from ecco-branch)
996    
997    checkpoint50h_post
998    o new package "land": provide surface BC for AIM.
999    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1000    o AIM: use true log-P extrapolation for near surface temp (= as in
1001        F.Molteni paper) ; update aim.5l_cs output.
1002    o New variable in PARM03 for more flexible pickups
1003    o somewhat cleaned package initialisation sequence for
1004      ctrl/ cost/ ecco/ in packages_... routines
1005    
1006    checkpoint50g_post
1007    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1008      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1009      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1010        made the default because of faster convergence than ADI
1011    
1012    checkpoint50f_post
1013    o exf totally restructured
1014      - replaced all exf_set_ routines by one generic exf_set_gen.F
1015        and made sure it's still differentiable
1016      - split exf_getffields.F into new exf_bulkformulae.F
1017      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1018      - updated adjoint/makefile and relevant verif. accordingly
1019

1029    
1030    checkpoint50e_post
1031    o make KPP work with PTRACERS
1032     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1033       nearly a copy of kpp_transport_s
1034     - there is no analogue to SurfaceTendencyS, so I have to use
1035       gPtr(of the surface layer) instead
1036    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1037    checkpoint50e_pre
1038    
1039    checkpoint50d_post
1040    o change kpp output from multiple-record state files to single-record state
1041      files analogous to write_state.F
1042    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1043      analogous to the cg2d-related output.
1044    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1045      so that writing to internal file fn (with length 512) fails.
1046    checkpoint50d_pre
1047    
1048    checkpoint50c_post
1049    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1050    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1051    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1052    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1053    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1054    
1055    checkpoint50c_pre
1056    Merging from release1_p13:
1057    o bug fix for pkg/seaice dynamic solver
1058    o Added SEAICE_initialHEFF to pkg/seaice
1059    
1060    checkpoint50b_post
1061    o store u*,v* in gU,V instead of in guNm1,gvNm1
1062    o in order to put the momForcing out of the Adams-Bashforth:
1063      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1064      to timestep.F
1065    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1066    o re-generate output for highly sensitive test-exp:
1067       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1068    
1069    checkpoint50b_pre
1070    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1071    o corrected CPP option mismatch in exf_Bulk... functions for case
1072      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1073    
1074    checkpoint50a_post
1075    o Bug fix for merging between c50 and KPP.
1076      ikey was passed from thermodynamics to kpp_calc via
1077      common block rather than being recomputed in kpp_calc,
1078      in contradiction with new key itdkey.
1079      New key ikppkey created, and tamc.h headers updated.
1080    
1081    checkpoint50
1082    - 2nd step of merge with ecco-branch:
1083      merge changes in ecco-branch back into main trunk
1084    - bug fix in find_alpha
1085    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1086    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1087    - merged some sliced AD support routines
1088    
1089    checkpoint49
1090    merged from ecco-branch:
1091    o exf:
1092      - Enable initialisation of forcing fields to constant
1093        (runtime) values.
1094      - in exf_getffields.F
1095        Reduce i-/j-loop to interior domain, discarding overlaps.
1096        That also fixes wrong TAF-key computations for key_1, key_2
1097        with bulf formulae.
1098      - exf_init.F modify #ifdef for exf_init_evap
1099      - exf_getffieldrec.F, ctrl_getrec.F
1100        The following INT-usages are not safe:
1101          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1102          fldcount = int(fldsecs/fldperiod) + 1
1103        and were modified.
1104    o autodiff: checkpoint_lev...
1105      - updated storing for bulk formulae (some arrays were missing)
1106      - added state for seaice package
1107      - synchronized with main branch
1108    o DIVA:
1109      Modif.s in
1110      - the_main_loop.F
1111      - the_model_main.F
1112      and added cost_final_restore.F cost_final_store.F
1113      o With these changes, it is possible to fully separate
1114        the first forward run to compute the cost function (mdthe_main_loop)
1115        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1116        into separate model executions.
1117        This enables better tuning of DIVA to given queue sizes.
1118      o Loss of cost function value in consecutive DIVA runs is
1119        fixed by storing to 'costfinal' file.
1120      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1121        beginning/end of adjoint integration is accounted for.
1122      The current changes apply to TAF-1.4.26.
1123      TAF has one remaining bug, requiring one manual change
1124      (see MITgcm manual).
1125    o cal: synchronized between MAIN and ecco-branch
1126    
1127    checkpoint48i_post
1128    o Changes to restore differentiability of code w.r.t. previous tag
1129      (mostly adding new routines to make list and replacing
1130      pressure by totPhiHyd).
1131    o Updated and merged grdchk package
1132      - has both ADM and TLM checks
1133      - works for single- and multi-proc.
1134      - output cleaned
1135      - worked successfully for parallel DIVA
1136    o genmake:
1137      - Adding -platform=SP4
1138      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1139    o Modif. for DIVA:
1140      ctrl_unpack should not be called in intermediate DIVA interval.
1141      (similar thing would apply for active files such as
1142      tbar, sbar, psbar, which should not be reinitialised;
1143      only relevant for ecco-branch)
1144    
1145    checkpoint48h_post
1146    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1147    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1148    o Added SEAICE_initialHEFF to pkg/seaice
1149    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1150    
1151    checkpoint48g_post
1152    --- EOS:
1153    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1154      store total Potential in totPhyHyd for diagnostics & EOS.
1155    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1156    --- Pressure/geopotential gradient:
1157    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1158    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1159      ( changes results of global_ocean_pressure )
1160    o NLFS + z-coord.: add eta*Rho' contribution.
1161    o accurate phiHyd when using interface-W at the middle between 2 centers
1162     ( changes results of ideal_2D_oce )
1163    o includes r* 2nd term in potential gradient.
1164    
1165    checkpoint48f_post
1166    Merging from release1_p12:

1173      (SBO) core products, including oceanic mass, center-of-mass,
1174      angular, and bottom pressure (see pkg/sbo/README.sbo).
1175    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1176      to avoid negative values in shallow regions.
1177      - updated verification/natl_box/results/output.txt
1178      - updated verification/lab_sea/results/output.txt
1179    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1180    o Added useSingleCpuIO option (see PARAMS.h).
1181    o Updated useSingleCpuIO option in mdsio_writefield.F to
1182      work with multi-field files, e.g., for single-file pickup.
1183    o pkg/seaice:
1184      - bug fix in growth.F: QNET for no shortwave case

1195    o dynamics: change definition of computational domain & adapt mom_fluxform
1196      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1197    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1198        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1199        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1200        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1201        inverted_barometer solid-body.cs-32x32x1
1202      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1203    
1204    checkpoint48d_post
1205    o in preparation for r*:
1206     a) use pre-computed gradient of hydrostatic potential:
1207        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1208     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1209        => affects results of glob_oce_pressure (different truncation error)  
1210      update output.txt of ideal_2D_oce & global_ocean_pressure
1211    
1212    checkpoint48d_pre
1213    o in preparation for r*:
1214      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1215      pass the 2 comp. of the grad. as arguments to momentum S/R.
1216      but for the moment, only used if it does not change the results.
1217    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1218    
1219    checkpoint48c_post
1220    Modifications in treatment of initial flux forcing controls
1221    to avoid extra storing of flux fields.
1222    
1223    checkpoint48c_pre
1224    o Added tidal_basin_2d experiment (currently 1D!)
1225    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1226    
1227    checkpoint48b_post
1228    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1229     (modification to pressure gradient not yet implemented)
1230    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1231      (for U & V) that are used for vertical advection of momentum.
1232    
1233    checkpoint48a_post
1234    o In preparation for r*, use temp. array to compute vertical transport
1235       in flux-form momentum pkg. => change results of few test-exp.
1236      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1237                        lab_sea, natl_box & plume_on_slope
1238    
1239    checkpoint48
1240    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1241    
1242    checkpoint47j_post
1243    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1244    o moved adexch from forward_step to addummy_in_stepping
1245    o added exch in ctrl_map_...
1246    o aveFreq.=0. at end of cost_final to avoid overwrite in
1247      reverse checkpointing loop
1248    o Yet more changes in gmredi:
1249      * adgmredi_calc_tensor
1250        avoiding all recomputation of gmredi_slope_limit
1251      * adgmredi_x/y/rtransport
1252        added flag for excessive storing to avoid recomp. of
1253        u/v/rtans, dTdx/y/z
1254        -> this is not really necessary and very memory-consuming
1255      * adgmredi_slope_psi:
1256        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1257      * gmredi_slope_limit
1258        re-activated full calculation of taperfct for case 'ac02'
1259    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1260    
1261    checkpoint47i_post
1262    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1263    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1264      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1265    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1266    o gmredi: fix few bugs.
1267    
1268    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1269    This will be a good checkpoint to plug into the ecco-branch.
1270    o few modif.'s to get latest version adjointed
1271      (mainly kick out code in ini_linear_phisurf)
1272    o modif's to run adjoint with exactConserv
1273    o case GM_BOLUS_ADVEC should be cleaned
1274      S/R gmredi_slope_psi should be cleaned
1275    o verification/carbon now has exactConserv=.TRUE.
1276    
1277    checkpoint47g_post
1278    o time-average AIM output: becomes independent from statvars time-average
1279      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1280    o After TAF bug fix:
1281      Tested adjoint of gmredi package.
1282      Tests were done with checkpoint47 rather than with latest
1283      checkpoint47f_post since the latter is broken for the adjoint
1284      verification/carbon/ contains both ADM and TLM gradient checks.
1285    Here they are, before they get changed/lost/stolen.
1286    Mostly modif.'s to fix numerical sensitivities.
1287    Gradient checks OK for
1288    - GM_taper_scheme:
1289      * clipping
1290      * ac02
1291      * linear
1292      * glw91
1293      * dm95
1294      * ldd97
1295    - GMREDI_OPTIONS:
1296      * GM_VISBECK_VARIABLE_K
1297      * GM_NON_UNITY_DIAGONAL
1298      * GM_EXTRA_DIAGONAL
1299      * GM_BOLUS_ADVEC
1300    in conjunction with data.gmredi parameters to be checked in
1301    in a few minutes under verification/carbon/code/
1302    
1303    checkpoint47f_post
