3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
6      configuration
7    o give MNC the ability to create additional files rather than
8      exceeding a specified file size limit "MNC_MAX_FILESIZE"
9      - the default is just less than 2GB which is a practical limit
10        on many systems
11    o Compute the non-local term using either KPP vertical diffusivity (=default)
12       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
13    
14    checkpoint55h_post
15    o add verification test "vermix"
16    o remove all the *_ioinc flags and replace with the single global
17      outputTypesInclusive flag
18    o allow to set a vertical profile of vertical diffusivity for T & S
19    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
20    o useMNC moved from data.mnc to data.pkg
21    
22    checkpoint55g_post
23    o Renaming carbon AD experiments to comply with testreport conventions
24    o Updating adjoint of Held-Suarez hs94.1x64x5
25    o Fixing directives for non-ECCO forward_step, after ECCO directives
26      have been fixed to avoid recomp. of do_oceanic_phys
27      Works well for global_ocean.90x40x15,
28      but recomp. issue remains for carbon
29    o Updating adjoint output for natl_box_adjoint after
30      pkg/ecco has been modified (see taga c55d_post)
31    
32    checkpoint55f_post
33    o rename to timeave_init_fixed
34    
35    checkpoint55e_post
36    o some delicate re-shuffle of store directives to avoid one
37      extra call of do_oceanic_physics
38      affects ecco_the_main_loop.F, do_oceanic_physics.F
39      checkpoint_lev1_directives.h
40    o NB: this may break global_ocean adjoint temporarily,
41      but it is clear how to fix it. Will do later, need this now.
42    
43    checkpoint55d_post
44    o ECCO specific cost function terms (up-to-date with 1x1 runs)
45    o ecco_cost_weights is modified to 1x1 runs
46    o modifs to allow observations to be read in as
47      single file or yearly files
48    o enable to read exf forcing fields as either
49      single file or yearly files (flag useExfYearlyFields)
50    checkpoint55d_pre
51    
52    o switch between 2-level and 3-level checkpointing
53    o add ability of MNC to write local and "partial" (eg. 2D slices where
54      the full 3D field is never actually stored) arrays to NetCDF files
55      with the correct (that is, the complete multi-dimensional) set of
56      array indicies
57      - used in mom_vecinv() to write the diagFreq output
58      - tested (demonstrated) in verification/aim.5l_cs
59    o further mnc-ification
60      - add verification/lab_sea to the list with mnc setups
61      - fix undefined mnc v-names in cd_code
62      - add kpp to mnc output (both snapshot and timeave)
63    o non-hydrostatic code
64      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
65        in calc_gw.F
66      - defaults to viscAh
67      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
68        friction or Leith) in non-hydrostatic mode, as long as there is
69        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
70    o pkg/cost
71      extend simple cost functions to treat time mean quantities
72      (T,U,V) via cost_accumulate_state from cost_tile
73    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
74        be 2 times larger than the minimum size the advection scheme requires.
75        now get a perfect conservation of salt in advect_cs test-exp (updated)
76    o GGL90 (Gaspar's TKE mixed layer)
77      - add horizontal diffusion of TKE, requires exchanges in
78        do_fields_blocking_exchanges, horizontal diffusivity is zero by
79        default. In OPA there is no horizontal diffusion of TKE but the
80        mixing coefficients are computed from a horizontal average of TKE of
81        6 points or so. I think that diffusion has a little more physical
82        justification.
83      - clean up ggl90_calc in the hope of reducing memory usage (this hope
84        was in vain)
85      - mask tke-variable in ggl90_init
86    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
87    o fix biharmonic diffusion on CS-grid.
88    o more obcs stuff
89      - added obcs_external_fields_load as an alternative to the EXF-pkg option
90        for reading boundary values. This routine is called from
91        obcs_prescribe_read
92      - updated obcs_check
93      - changed sponge layer relaxation parameter units for days to seconds
94      - turned off sponge layer by default
95      - changed argument list of OBCS_CALC to myTime+deltaTclock
96      - fixed about 35 bugs in obcs_external_fields_load
97    
98    checkpoint55c_post
99    o obcs stuff
100      - new runtime flags useOBCSprescribe, useOBCSbalance
101      - re-arranged obcs_calc
102      - moved exf_getobcs to obcs_prescibe_read
103        obcs_prescibe_read is called after ORLANSKI stuff
104        and independent of it (executable can contain all).
105      - updated obcs_check
106      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
107        These may be necessary only if tangential velocities are
108        prescribed at OB, not sure, needs testing.
109    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
110      which simplifies the calls and passes the ifc check-bounds test
111    
112    checkpoint55b_post
113    o add a 2D scalar, Z location, exchange_2 routine.
114    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
115      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
116      affects advect_cs results (for the wrong reason): update output.txt
117    o use a more standard discretization for biharmonic viscosity ;
118     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
119      affects results of dome set-up: update output.txt
120    o fix gad_advection.F (CubedSphere part), back to version 1.23
121    o fix bug in mom_vi_del2uv.F (CubedSphere part).
122    
123    checkpoint55a_post
124    o merged code to
125      * prescribe/read time-dependent open boundaries
126        (works in conjunction with exf, cal)
127      * sponge layer code for open boundaries
128      * each boundary N/S/E/W now has its own CPP option
129        (healthy for the adjoint)
130    
131    checkpoint55
132    o up-to-date adjoint of previous breaks
133      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
134      - global_ocean_ebm: adjoint still needs fix (TLM ok)
135      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
136      - carbon: * remove tr1-related adjoint verification
137                * add ptracer as control variable
138    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
139      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
140    
141    checkpoint54f_post
142    o in verification/carbin/ remove experiment related to
143      ALLOW_PASSIVE_TRACER (array tr1 etc)
144      code_ad/ input_ad/ results_ad
145    
146    o add two new packages
147      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
148        + subject to optimization (memory)
149      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
150        + subject to reordering (many GOTOs in the original code)
151        + so far opps is called for every (i,j) point, and then operates in
152          the vertical; one may want to reorder the scheme in order operate in
153          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
154          fields)
155    o overhaul of IO so that we now have flags for MDSIO and/or MNC
156      - all verification tests compile and run with linux_ia32_g77
157      - defaults are compatible with current input files--nothing
158        should change if you were not previously using MNC
159      - MNC output has been added in numerous places (eg. timeave)
160        but there are still a few writes not yet do-able with MNC
161        (this is in progress)
162      - flags now allow for either/or/both use of MDSIO and MNC and
163        documentation will soon follow
164      - numerous small formatting cleanups for ProTeX
165    o add version info (via BUILD_INFO.h) to MNC and stdout
166    
167    checkpoint54e_post
168    o add two new packages
169      - pp81 (Packanowski and Philander, 1981), Richardson number and
170        stratification dependent mixing
171      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
172      - these scheme operate in a similar manner as KPP (without ghat, of
173        course), however there is only one diffusivity that is used for both
174        temperature and salinity (and passive tracers)ç
175    o add offline package
176    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
177      provided by Stephanie Dutkiewicz
178    o genmake2: add ability to search for C compilers and cleanup test output
179      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
180    
181    checkpoint54d_post
182    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
183    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
184      leading to additional shift by 5 days each year of integration
185       (i.e. leading to considerable offset over the years)
186    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
187    o start with no AB and no initial filtering (staggerTimeStep):
188      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
189    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
190      (external loading & cpl import/export stay in forward_step.F)
191    o update coupling interface to work with new staggerTimeStep
192    o change MDSIO ptracers_pickup.
193    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
194    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
195    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
196    
197    checkpoint54c_post
198    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
199      this affects (truncation error) output.txt of test-exp:
200       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
201    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
202    o change Qnet to always be the net heat flux, (+upward).
203      affects (truncation error) output of natl_box exp.: updated
204    o define the max number of passive tracers in PTRACERS_SIZE.h
205    o start to test mnc routinely in exp0
206    o add sea-ice loading (sIceLoad) as a new forcing field.
207    
208    checkpoint54b_post
209    o add testreport "-j JOBS" option for parallel builds (tested and pretty
210       impressive on Altix and Opteron systems)
211    o diagnostics can now write NetCDF files through the mnc package
212    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
213    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
214    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
215      affects (truncation error) output of lab_sea & natl_box exp.: updated
216    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
217    
218    checkpoint54a_post
219    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
220    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
221    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
222    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
223      + internal_wave (shift in writing cg2d_ini_res)
224    checkpoint54a_pre
225    
226    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
227      - modified verification/lab_sea and natl_box_adjoint accordingly
228    
229    checkpoint54
230    checkpoint53g_post
231    o prepare splitting of thermodynamics: store convect.counter in common block
232    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
233      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
234    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
235    o new parameter "nShapS": allow to treat differently S from T (nShapT)
236    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
237    o restore adjointability
238    
239    checkpoint53f_post
240    o modifications that affect AIM experiment results (update output.txt):
241      - no advection of S at top interface Nr (pkg/generic_advdiff)
242      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
243    o AIM pkg:
244      - include stability function into surf.Flux derivative relative to Tsurf
245      - calculate clear-sky radiation & surface temp. change (for diagnostics)
246    
247    checkpoint53e_post
248    o merged cylindrical coord configuration
249    o added rotating_tank experiment
250    checkpoint53e_pre
251    
252    checkpoint53d_post
253    o faulks upgraded: re-generate output.txt that have changed:
254       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
255    o Added Bryan and Lewis, 1979, vertical diffusivity profile
256    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
257    o added Sadourny discretization of Coriolis
258      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
259      - re-enabled use of omega3 (useAbsVorticity)
260    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
261      vector-invariant equations
262      - note: does *NOT* yet use same variable visc. for no-slip BC's.
263    o recoded the lateral boundary conditions for non-hydrostatic w, this time
264      hopefully without new bugs
265      - still to do: biharmonic friction for non-hydrostatic w
266    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
267    o regenerated output for global_ocean_ebm (using -ieee)
268    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
269      of mom_common/
270      - simple re-arrangement of instructions within computing loop
271    checkpoint53d_pre
272    
273    checkpoint53c_post
274    o new version of coupler for AIM+thSIce and Ocean models
275     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
276     - land: change Evaporation of snow
277     - aim with thSIce: fix bug in snow-precip.
278    o changes to calc_gw.F
279     - bug fix for w^2 term near the bottom boundary
280     - (hopefully) improve the lateral slip boundary condtions for use with
281        partial/looped cells
282      - because the bug fix changes two verification experiments anyway (exp5
283        and plume on slope), change the lateral boundary condition from half slip
284        to the value of no_slip_sides
285    o ebm package wasnt quite up to the parallel task. Fixed that.
286    o Adjoint of EBM package + verification
287      * TLM OK
288      * ADM not sufficient accuracy yet (needs further testing)
289    
290    checkpoint53b_post
291    o Commiting new energy balance model to repository
292      * package is pkg/ebm
293      * verif. is verification/global_ocean_ebm
294      * references are in ebm_driver.F
295    C      * X. Wang, P. Stone and J. Marotzke, 1999:
296    C        Global thermohaline circulation. Part I:
297    C        Sensitivity to atmospheric moisture transport.
298    C        J. Climate 12(1), 71-82
299    C      * X. Wang, P. Stone and J. Marotzke, 1999:
300    C        Global thermohaline circulation. Part II:
301    C        Sensitivity with interactive transport.
302    C        J. Climate 12(1), 83-91
303    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
304    C        Destabilization of the thermohaline circulation
305    C        by atmospheric eddy transports.
306    C        J. Climate 7(12), 1870-1882
307    o Will need long integration testing.
308    checkpoint53b_pre
309    
310    o created pkg/mom_common in preparation for variable viscosity code
311    o renamed and split ini_mnc_io
312    o pkg/land: only liquid water can diffuse or run-off
313    o AIM using land: soil wetness availability account for snow
314    o added printMapIncludesZeros to EEPARMS namelist
315    
316    checkpoint53a_post
317    o restore TAMC compatiility for exf_constants.h
318      (no usage of _d in .h)
319    o Additional storing in KPP in an attempt to fix
320      TAMC problem with adjoint of KPP code.
321      (no success...)
322      Identical code works fine with TAF.
323    o Fixed verification/natl_box_adjoint experiments.
324      Initial conditions for Experiments 4 and 5 are now
325      set to "SEAICE_initialHEFF=0", which is more reasonable,
326      and hence gives results closer to that of Experiment 2.
327      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
328    
329    checkpoint53
330    o stable checkpoint with up to date adjoint
331      TLM tests only run for 1st grdchk at the moment. Its unclear if
332      this is a code problem or a problem with resetting code for g_
333      variables that is being autogenerated wrong.
334      Otherwise:
335       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
336       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
337         are both still in chaos following their security messes.
338    
339    checkpoint52n_post
340    o various build (mostly genmake2) changes including:
341      - ability to build/run more easily within Cygwin and MacOS X
342      - more complicated Makefiles with a stronger dependence on Gnu Make
343    o pkg/seaice modifications
344      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
345        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
346        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
347      - changed proxy for geostrophic velocity and updated
348        verification/lab_sea/results/* accordingly
349      - removed ADI dynamic solver from pkg/seaice
350      - replaced all occurrences of 1/CSTICE or 1/CSUICE
351        they caused a segmentation fault under certain circumstances
352      - removed unused field WATR
353    o bug fix in exf-package:
354      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
355         now reflect that.
356    o small fixes in the cal-package:
357      - set reference date to first of January for the 'model'-calendar
358      - failing of cal_CheckDate in cal_FullDate now actually results in a
359        warning
360    o small modifications in exf-package to increase flexibility:
361      - change climtempfreeze from a constant to a runtime parameter that
362        is specified in data.exf_clim (default = -1.9)
363      - introduce runtime parameter windstressmax (default = 2.0) that is
364        specified in data.exf
365    o fix in pkg/thsice:
366      - update Evap (Tsf changes) to be consistent with Latent heat flux
367      - maintain snow precipitation unchanged (even if Tsf >=0).
368     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
369    
370    checkpoint52m_post
371    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
372      this does not change any of the results, because myIter=0 in swfrac always
373      lead to jwtype=2 (the default anyway), but the call makes little sense
374      as a default
375    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
376    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
377      atmospheric model (AIM) to use it ; add a "slab ocean" component.
378    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
379    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
380    o extending useSingleCpuIO option to work with new exch2 I/O format
381      - old-style, missing-tile I/O is still accessible by defining CPP
382        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
383    o monitor package can write to NetCDF files and/or STDOUT
384    o fix re-definition bug in MNC_GRID_INIT_ALL()
385    o doc/api_reference added
386      - a framework for building an API Reference Manual using all
387        the "protex" comments embedded in the code
388      - see pkg/generic_advdiff, pkg/mnc for examples
389    o MNC:

429    o fixed bug introduced in pkg/monitor
430    o accuracy ctrlprec = 32 insuffient for gradient checks using
431      averaged fields (I/O via cost_averages)
432      -> use ctrl.h in active_file*.F to control I/O precision.
433    o paramter list of CALL ADTHE_MAIN_LOOP
434    o added initial do_the_model_io to ecco
435    o set all ...Freq to zero after cost_final

438    
439    checkpoint52j_post
440    o fix nchklev in tamc.h for global_ocean...
441    o Bringing flow and store directives up-to-date
442    o Really weird thing!
443      call do_the_model_io from the_main_loop with parameters
444      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
445      TAF places a faulty re-call of initialise_varia
446      after cost_final call which should not be there!
447    checkpoint52j_pre
448    
449    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
450      error messages

478    o added useSingleCPUIO flag to monitor.F and mon_out.F
479    o added temporary hack for sea-ice dynamics on the cube:
480      metric terms are ignored and it is assumed that
481      there is no sea-ice on cube faces 1, 2, 4, and 5.
482    
483    checkpoint52f_post
484    o added exch2 cube routines to pkg/exch2

488    
489    checkpoint52e_post
490    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
491      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
492    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
493      to work with implicit vertical advection and AB ;
494    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
495    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
496     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
497    checkpoint52e_pre
498    
499    o fix bug in impldiff when Nr=1 or Nr=2.
500    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
501    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
502    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2

509    o re-tiled many expts to allow comparison in multi-processor mode
510      - updated output accordingly
511      - changed hs94.128x64x5 to use intial T from file rather than use the
512        random number generator
513    o add infrastructure in model routines for fizhi and gridalt packages
514    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
515    o changes to permit hi-res, cubed-sphere, configuration
516      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
517      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
518      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
519        of surface winds for the cube
520      (A verification experiment, based on global_ocean.cs32x15, but with
521       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
522       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
523       complete with example surface forcing files and matlab scripts to look
524       at the output and compare it with that of global_ocean.cs32x15.)
525    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
526       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
527       to conform to the common rule.
528    o check-in the first version of the coupler + interfaces for multi-components
529       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
530       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
531       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
532       - ocean and atmos. share the same horizontal grid (no interpolation).
533       - exchanges between component and coupler is done in forward_step
534    o new verification experiment, cpl_aim+ocn:
535       coupled ocean - AIM atmosphere on cs32 grid.
536    
537    checkpoint52d_pre
538    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
539    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
540    
541    checkpoint52c_post
542    o Fixing OPTIONS files for use of exf:
543      - ALLOW_ECCO not needed
544      - ECCO_CPPOPTIONS.h should not be included from
545        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
546        as has been the case in the past
547      - All cal/exf related options are currently set in
548        single header file. Should remain so until we
549        agree on a consistent new policy.
550    o Removed all CPP options for cal package.
551      cal has no more CPP options.
552    o modified STOREs in GAD_ADVECTION
553    o corrected key comp. for passkey
554    
555    checkpoint52b_post

558     - modify fluxes but do not change theta directly;
559     - light cleaning of bulk_force pkg (still needed with thsice).
560     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
561       + output_thsice.txt to test thsice & bulk_force pkgs.
562    o put back grid & coriolis monitor output.
563    checkpoint52b_pre
564    
565    o call "do_the_model_io" at the beginning (=> dump initial state)
566    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
567    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
568      (need info on NUMBER_OF_PTRACERS)
569    o missing PTRACERS headers in some routines
570    o default tamc.h in pkg/autodiff supposed to crash
571      to ensure proper customization
572    
573    checkpoint52a_post
574    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
575      - moved surfaceTendencyTice from pkg/seaice to main code
576      - subroutine FREEZE_SURFACE now limits only surface temperature
577        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
578        => new output.txt for global_ocean.cs32x15 & global_with_exf
579      - keep the old version of FREEZE for backward compatibility;
580        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
581      - corresponding modifs for TAF directives
582    o added surface flux output variables to TIMEAVE_STATVARS

589    o some bug fixes for #undef REAL4_IS_SLOW
590    
591    checkpoint52 = ecco_c52_e35
592    o after testing adjoints of checkpoint51u_post
593    
594    checkpoint51u_post
595    o this is the post-merge tag of the ecco-branch
596      (needs another clean checkout and re-testing)
597    o various natl_box_adjoint configs and results
598      but no input fields
599    o obcs adjoint not yet merged!
600    o adding ECCO global 1x1 and 2x2 degree configs
601    o updated/extended some store directives for seaice
602    o pkg/ecco now containes ecco-specific part of cost function
603    o top level routines the_main_loop, forward_step
604      supersede those in model/src/
605      previous input data.cost now in data.ecco
606      (new namelist ecco_cost_nml)
607    o in ctrl/ cleaned some cross-dependencies and updated CPP options
608    
609    checkpoint51t_post
610    o this is the pre-merge tag of the ecco-branch
611    
612    checkpoint51s_post
613    o cleanup: removed various obsolete #define-s
614    o pkg/grdchk
615      - renamed 'ph-grd 3' to 'grad-res'
616      - merged from ecco-branch
617        (remaining bug fixes for obcs gradient checks)
618      - additional high-precision output for testreport
619        (grep for 'precision_grdchk_result')
620    
621    checkpoint51r_post
622    o cleaned up or removed CPP_OPTIONS.h files
623    o updated results for some of the tests to reflect the new
624      optfiles (-ieee: -O0 instead of -O3)
625    
626    checkpoint51q_post
627    o cd_code:
628      - moved cd_scheme.F -> cd_code_scheme.F
629      - separate read_checkpoint from cd_code_ini_vars.F
630      - separated cd_code part from write_checkpoint
631      - updated AD_SOURCE, generated .flow

633      - Moving cd_code specific store dir.s to pkg/cd_code
634    o ctrl package totally restructured
635      - pack/unpack now optional and decoupled from
636        xx_/adxx_ I/O
637      - ctrl_pack/unpack cleaned

639      - confined inclusion of AD_CONFIG.h to where necessary.
640    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
641    
642    checkpoint51p_post
643    o create initial cd_code package
644      - WARNING: the initialization of fields within packages
645        is broken because INI_FIELDS (where READ_CHECKPOINT is
646        called) is called *before* PACKAGES_INIT_VARIABLES.
647        This seems to be backwards since
648        1) its important to initially zero the entire field including
649           the "halo" region
650        2) zeroing needs to be done *before* reading pickup info
651           and the pickup call might or might not happen in any
652           particular run
653      - this needs an overhaul for R2
654    o cleanup verification/*/code/GMREDI_OPTIONS.h
655    o cleanup testreport
656    
657    checkpoint51o_post
658    o bringing AD-related verif's up to date with genmake2

667      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
668        change rho -> rho-rhoConst
669      - replace call find_rho to find_rhonum
670    o initialisation of rFlx extended to full array (required by TAF)
671      and shifted to thermodynamics
672    o removed PTRACERS.h in ptracers routine
673    o added surfacetendencyPtr to S/R parameter list pracers_forcing

691        (this means new output.txt for global_ocean.90x40x15,
692         global_ocean.cs32x15, and global_with_exf)
693    o added surface flux output variables to TIMEAVE_STATVARS
694    
695    checkpoint51n_pre
696    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

718    o enable to apply restoring on S & T only in a latitude band.
719    o update output (external_forcing_surf modif. change truncation errors)
720       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
721    
722    checkpoint51k_post
723    o change default to: useNHMTerms=.FALSE.
724     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):

801    o AIM : add stratospheric drag in the upper level
802    
803    checkpoint51d_post
804    o change function ILNBLNK (=> last non-blank char.) to return zero
805      (instead of the string length) when the string. char is empty
806    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
807    o modif's to restore TAMC compatibility
808      - avoid "_d" constructs in PARAMETER declarations
809      - avoid interrupting lines by comment lines
810    o Use cluster local disks for purely local I/O
811      vs. globally visible disks needed for ctrl stuff
812      (merged from ecco-branch)
813      - new active_file_loc... and mdsio_..._loc routines
814      - affected packages: autodiff, ctrl, grdchk, mdsio
815    
816    checkpoint51c_post
817    o introducing integer flag debugLevel
818      - debLevZero: suppress all output
819      - debLevA: standard
820      - debLevB: equivalent to current debugMode=.TRUE.
821    o introducing pathname variable mdsioLocalDir for mdsio
822      that can be specified at runtime
823      (relevant for cluster I/O to local disk)
824    `
825    >>>checkpoint51b_post
826    adjoint of ptracers
827    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
828    o extended state in checkpoint_lev?, etc.
829    o alternative ctrl/cost with tr1 or ptracer
830    o new comlev1_bibj_ptracers
831    o new ptracers.flow
832    o made ptracers_forcing same as external_forcing_s
833    o added verification for adjoint with ptracers
834      - adm. grdchk fail so far
835      - tlm. grdchk OK
836      - checked tapelev/comlev recomputations: OK
837    <<<checkpoint51b_pre
838    
839    checkpoint51a_post
840    o added code for biogeochemistry package
841      - new pkgs: dic, gchem
842      - new subroutine in ptracers
843    o modify code for biogeo packages
844      - in model/src and pkg/ptracers
845    
846    checkpoint51
847    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
848      - autodiff, ctrl, exf, grdchk, seaice
849      kept separate packages
850      - cost, ecco, obcs
851    o updating verification/internal_wave, verification/lab_sea
852      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
853    
854    checkpoint50i_post
855    o Preparing next differentiable checkpoint and sync
856      of MAIN vs. ecco-branch
857      - 1st step: this one is differentiable
858      - 2nd step: next(! not this) checkpoint will have updated packages
859                  from ecco-branch)
860    
861    checkpoint50h_post
862    o new package "land": provide surface BC for AIM.
863    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
864    o AIM: use true log-P extrapolation for near surface temp (= as in
865        F.Molteni paper) ; update aim.5l_cs output.
866    o New variable in PARM03 for more flexible pickups
867    o somewhat cleaned package initialisation sequence for
868      ctrl/ cost/ ecco/ in packages_... routines
869    
870    checkpoint50g_post
871    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
872      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
873      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
874        made the default because of faster convergence than ADI
875    
876    checkpoint50f_post
877    o exf totally restructured
878      - replaced all exf_set_ routines by one generic exf_set_gen.F
879        and made sure it's still differentiable
880      - split exf_getffields.F into new exf_bulkformulae.F
881      - exf_inscal_/exf_outscal_ suffixes consistent with field names
882      - updated adjoint/makefile and relevant verif. accordingly
883    
884    checkpoint50f_pre

886          + change Evap over land. (update aim.5l_cs output)
887     o added missing .cvsignores and made uniform across expts
888     o changed configuration of tidal_basin_2d expt
889     o added pkg/debug functions for tracing code in fatal crashes
890     o tidied pkg/monitor to use MONITOR_OPTIONS.h
891     o new fn in pkg/monitor to stop model if solution grows too big
892     o removed lots of single quotes from comments
893    
894    checkpoint50e_post
895    o make KPP work with PTRACERS
896     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
897       nearly a copy of kpp_transport_s
898     - there is no analogue to SurfaceTendencyS, so I have to use
899       gPtr(of the surface layer) instead
900    o add a new platform SunFire+mpi (SunFire 15000) to genmake
901    checkpoint50e_pre
902    
903    checkpoint50d_post
904    o change kpp output from multiple-record state files to single-record state
905      files analogous to write_state.F
906    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
907      analogous to the cg2d-related output.
908    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
909      so that writing to internal file fn (with length 512) fails.
910    checkpoint50d_pre
911    
912    checkpoint50c_post
913    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
914    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
915    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
916    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
917    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
918    
919    checkpoint50c_pre
920    Merging from release1_p13:
921    o bug fix for pkg/seaice dynamic solver
922    o Added SEAICE_initialHEFF to pkg/seaice
923    
924    checkpoint50b_post
925    o store u*,v* in gU,V instead of in guNm1,gvNm1
926    o in order to put the momForcing out of the Adams-Bashforth:
927      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
928      to timestep.F
929    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
930    o re-generate output for highly sensitive test-exp:
931       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
932    
933    checkpoint50b_pre
934    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
935    o corrected CPP option mismatch in exf_Bulk... functions for case
936      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
937    
938    checkpoint50a_post
939    o Bug fix for merging between c50 and KPP.
940      ikey was passed from thermodynamics to kpp_calc via
941      common block rather than being recomputed in kpp_calc,
942      in contradiction with new key itdkey.
943      New key ikppkey created, and tamc.h headers updated.
944    
945    checkpoint50
946    - 2nd step of merge with ecco-branch:
947      merge changes in ecco-branch back into main trunk
948    - bug fix in find_alpha
949    - more storing in gmredi_calc_tensor.F, kpp_routines.F
950    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
951    - merged some sliced AD support routines
952    
953    checkpoint49
954    merged from ecco-branch:
955    o exf:
956      - Enable initialisation of forcing fields to constant
957        (runtime) values.
958      - in exf_getffields.F
959        Reduce i-/j-loop to interior domain, discarding overlaps.
960        That also fixes wrong TAF-key computations for key_1, key_2
961        with bulf formulae.
962      - exf_init.F modify #ifdef for exf_init_evap
963      - exf_getffieldrec.F, ctrl_getrec.F
964        The following INT-usages are not safe:
965          fldsecs  = int(fldsecs/fldperiod)*fldperiod
966          fldcount = int(fldsecs/fldperiod) + 1
967        and were modified.
968    o autodiff: checkpoint_lev...
969      - updated storing for bulk formulae (some arrays were missing)
970      - added state for seaice package
971      - synchronized with main branch
972    o DIVA:
973      Modif.s in
974      - the_main_loop.F
975      - the_model_main.F
976      and added cost_final_restore.F cost_final_store.F
977      o With these changes, it is possible to fully separate
978        the first forward run to compute the cost function (mdthe_main_loop)
979        and adjoint runs over individual DIVA intervals (adthe_main_loop)
980        into separate model executions.
981        This enables better tuning of DIVA to given queue sizes.
982      o Loss of cost function value in consecutive DIVA runs is
983        fixed by storing to 'costfinal' file.
984      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
985        beginning/end of adjoint integration is accounted for.
986      The current changes apply to TAF-1.4.26.
987      TAF has one remaining bug, requiring one manual change
988      (see MITgcm manual).
989    o cal: synchronized between MAIN and ecco-branch
990    
991    checkpoint48i_post
992    o Changes to restore differentiability of code w.r.t. previous tag
993      (mostly adding new routines to make list and replacing
994      pressure by totPhiHyd).
995    o Updated and merged grdchk package
996      - has both ADM and TLM checks
997      - works for single- and multi-proc.
998      - output cleaned
999      - worked successfully for parallel DIVA
1000    o genmake:
1001      - Adding -platform=SP4
1002      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1003    o Modif. for DIVA:
1004      ctrl_unpack should not be called in intermediate DIVA interval.
1005      (similar thing would apply for active files such as
1006      tbar, sbar, psbar, which should not be reinitialised;
1007      only relevant for ecco-branch)
1008    
1009    checkpoint48h_post
1010    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1011    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1012    o Added SEAICE_initialHEFF to pkg/seaice
1013    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1014    
1015    checkpoint48g_post
1016    --- EOS:
1017    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1018      store total Potential in totPhyHyd for diagnostics & EOS.
1019    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1020    --- Pressure/geopotential gradient:
1021    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1022    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1023      ( changes results of global_ocean_pressure )
1024    o NLFS + z-coord.: add eta*Rho' contribution.
1025    o accurate phiHyd when using interface-W at the middle between 2 centers
1026     ( changes results of ideal_2D_oce )
1027    o includes r* 2nd term in potential gradient.
1028    
1029    checkpoint48f_post
1030    Merging from release1_p12:
1031    o Modifications for using pkg/exf with pkg/seaice
1032      - improved description of the various forcing configurations

1034      - units/sign fix for evap computation in exf_getffields.F
1035      - updated verification/global_with_exf/results/output.txt
1036    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1037      (SBO) core products, including oceanic mass, center-of-mass,
1038      angular, and bottom pressure (see pkg/sbo/README.sbo).
1039    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1040      to avoid negative values in shallow regions.
1041      - updated verification/natl_box/results/output.txt
1042      - updated verification/lab_sea/results/output.txt
1043    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1044    o Added useSingleCpuIO option (see PARAMS.h).
1045    o Updated useSingleCpuIO option in mdsio_writefield.F to
1046      work with multi-field files, e.g., for single-file pickup.
1047    o pkg/seaice:
1048      - bug fix in growth.F: QNET for no shortwave case
1049      - added HeffFile for specifying initial sea-ice thickness
1050      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1051    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1052      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1053    o pkg/seaice:
1054      - adjoint-friendly modifications
1055      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1056    
1057    checkpoint48e_post
1058    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1059    o dynamics: change definition of computational domain & adapt mom_fluxform
1060      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1061    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1062        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1063        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1064        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1065        inverted_barometer solid-body.cs-32x32x1
1066      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1067    
1068    checkpoint48d_post
1069    o in preparation for r*:
1070     a) use pre-computed gradient of hydrostatic potential:
1071        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1072     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1073        => affects results of glob_oce_pressure (different truncation error)  
1074      update output.txt of ideal_2D_oce & global_ocean_pressure
1075    
1076    checkpoint48d_pre
1077    o in preparation for r*:
1078      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1079      pass the 2 comp. of the grad. as arguments to momentum S/R.
1080      but for the moment, only used if it does not change the results.
1081    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1082    
1083    checkpoint48c_post
1084    Modifications in treatment of initial flux forcing controls
1085    to avoid extra storing of flux fields.
1086    
1087    checkpoint48c_pre
1088    o Added tidal_basin_2d experiment (currently 1D!)
1089    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1090    
1091    checkpoint48b_post
1092    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1093     (modification to pressure gradient not yet implemented)
1094    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1095      (for U & V) that are used for vertical advection of momentum.
1096    
1097    checkpoint48a_post
1098    o In preparation for r*, use temp. array to compute vertical transport
1099       in flux-form momentum pkg. => change results of few test-exp.
1100      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1101                        lab_sea, natl_box & plume_on_slope
1102    
1103    checkpoint48
1104    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1105    
1106    checkpoint47j_post
1107    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1108    o moved adexch from forward_step to addummy_in_stepping
1109    o added exch in ctrl_map_...
1110    o aveFreq.=0. at end of cost_final to avoid overwrite in
1111      reverse checkpointing loop
1112    o Yet more changes in gmredi:
1113      * adgmredi_calc_tensor
1114        avoiding all recomputation of gmredi_slope_limit
1115      * adgmredi_x/y/rtransport
1116        added flag for excessive storing to avoid recomp. of
1117        u/v/rtans, dTdx/y/z
1118        -> this is not really necessary and very memory-consuming
1119      * adgmredi_slope_psi:
1120        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1121      * gmredi_slope_limit
1122        re-activated full calculation of taperfct for case 'ac02'
1123    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1124    
1125    checkpoint47i_post
1126    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1127    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1128      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1129    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1130    o gmredi: fix few bugs.
1131    
1132    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1133    This will be a good checkpoint to plug into the ecco-branch.
1134    o few modif.'s to get latest version adjointed
1135      (mainly kick out code in ini_linear_phisurf)
1136    o modif's to run adjoint with exactConserv
1137    o case GM_BOLUS_ADVEC should be cleaned
1138      S/R gmredi_slope_psi should be cleaned
1139    o verification/carbon now has exactConserv=.TRUE.
1140    
1141    checkpoint47g_post
1142    o time-average AIM output: becomes independent from statvars time-average
1143      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1144    o After TAF bug fix:
1145      Tested adjoint of gmredi package.
1146      Tests were done with checkpoint47 rather than with latest
1147      checkpoint47f_post since the latter is broken for the adjoint
1148      verification/carbon/ contains both ADM and TLM gradient checks.
1149    Here they are, before they get changed/lost/stolen.
1150    Mostly modif.'s to fix numerical sensitivities.
1151    Gradient checks OK for
1152    - GM_taper_scheme:
1153      * clipping
1154      * ac02
1155      * linear
1156      * glw91
1157      * dm95
1158      * ldd97
1159    - GMREDI_OPTIONS:
1160      * GM_VISBECK_VARIABLE_K
1161      * GM_NON_UNITY_DIAGONAL
1162      * GM_EXTRA_DIAGONAL
1163      * GM_BOLUS_ADVEC
1164    in conjunction with data.gmredi parameters to be checked in
1165    in a few minutes under verification/carbon/code/
1166    
1167    checkpoint47f_post
1168    Merging from release1_p10:
1169    o modifications for using pkg/exf with pkg/seaice
1170      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1171        and SEAICE_EXTERNAL_FLUXES
1172      - pkg/exf CPP options EXF_READ_EVAP and
1173        EXF_NO_BULK_COMPUTATIONS
1174      - usage examples are Experiments 8 and 9 in
1175        verification/lab_sea/README
1176      - verification/lab_sea default experiment now uses
1177        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1178    
1179    checkpoint47e_post
1180    o created a tag prior to creating a branch
1181    
1182    checkpoint47d_post
1183    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1184      at the bottom boundary had an erroneous half slip boundary condition
1185    o added bottom drag and no slip boundary condition capabilities to
1186      oceanic pressure coordinates code
1187    o added new verification experiment global_ocean_pressure, this experiment is
1188      also described in the tutorial section of the manual
1189    checkpoint47d_pre
1190    
1191    checkpoint47c_post
1192    o Added a verification experiment for a global cubed-sphere ocean run
1193      -  verification/global_ocean.cubed32x32x30
1194      -  uses pkg/therm_seaice and pkg/bulk_forcing
1195    
1196    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1197    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1198      when using P-coordinate; only implemented for atmospheric config.
1199    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1200      NOTES: requires option NONLIN_FRSURF to be "#define".
1201    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1202    
1203    checkpoint47b_post
1204    Merging from release1_p9:
1205    o pkg/seaice
