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

422    o accuracy ctrlprec = 32 insuffient for gradient checks using
423      averaged fields (I/O via cost_averages)
424      -> use ctrl.h in active_file*.F to control I/O precision.
425    o paramter list of CALL ADTHE_MAIN_LOOP
426    o added initial do_the_model_io to ecco
427    o set all ...Freq to zero after cost_final

431    checkpoint52j_post
432    o fix nchklev in tamc.h for global_ocean...
433    o Bringing flow and store directives up-to-date
434    o Really weird thing!
435      call do_the_model_io from the_main_loop with parameters
436      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
437      TAF places a faulty re-call of initialise_varia
438      after cost_final call which should not be there!
439    checkpoint52j_pre
440

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

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

550     - modify fluxes but do not change theta directly;
551     - light cleaning of bulk_force pkg (still needed with thsice).
552     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
553       + output_thsice.txt to test thsice & bulk_force pkgs.
554    o put back grid & coriolis monitor output.
555    checkpoint52b_pre
556    
557    o call "do_the_model_io" at the beginning (=> dump initial state)
558    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
559    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
560      (need info on NUMBER_OF_PTRACERS)
561    o missing PTRACERS headers in some routines
562    o default tamc.h in pkg/autodiff supposed to crash
563      to ensure proper customization
564    
565    checkpoint52a_post
566    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
567      - moved surfaceTendencyTice from pkg/seaice to main code
568      - subroutine FREEZE_SURFACE now limits only surface temperature
569        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
570        => new output.txt for global_ocean.cs32x15 & global_with_exf
571      - keep the old version of FREEZE for backward compatibility;
572        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

581    o some bug fixes for #undef REAL4_IS_SLOW
582    
583    checkpoint52 = ecco_c52_e35
584    o after testing adjoints of checkpoint51u_post
585    
586    checkpoint51u_post
587    o this is the post-merge tag of the ecco-branch
588      (needs another clean checkout and re-testing)
589    o various natl_box_adjoint configs and results
590      but no input fields
591    o obcs adjoint not yet merged!
592    o adding ECCO global 1x1 and 2x2 degree configs
593    o updated/extended some store directives for seaice
594    o pkg/ecco now containes ecco-specific part of cost function

596      supersede those in model/src/
597      previous input data.cost now in data.ecco
598      (new namelist ecco_cost_nml)
599    o in ctrl/ cleaned some cross-dependencies and updated CPP options
600    
601    checkpoint51t_post
602    o this is the pre-merge tag of the ecco-branch
603    
604    checkpoint51s_post
605    o cleanup: removed various obsolete #define-s
606    o pkg/grdchk
607      - renamed 'ph-grd 3' to 'grad-res'
608      - merged from ecco-branch
609        (remaining bug fixes for obcs gradient checks)
610      - additional high-precision output for testreport
611        (grep for 'precision_grdchk_result')
612    
613    checkpoint51r_post
614    o cleaned up or removed CPP_OPTIONS.h files
615    o updated results for some of the tests to reflect the new
616      optfiles (-ieee: -O0 instead of -O3)
617    
618    checkpoint51q_post
619    o cd_code:
620      - moved cd_scheme.F -> cd_code_scheme.F
621      - separate read_checkpoint from cd_code_ini_vars.F
622      - separated cd_code part from write_checkpoint
623      - updated AD_SOURCE, generated .flow

631      - confined inclusion of AD_CONFIG.h to where necessary.
632    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
633    
634    checkpoint51p_post
635    o create initial cd_code package
636      - WARNING: the initialization of fields within packages
637        is broken because INI_FIELDS (where READ_CHECKPOINT is
638        called) is called *before* PACKAGES_INIT_VARIABLES.
639        This seems to be backwards since
640        1) its important to initially zero the entire field including
641           the "halo" region
642        2) zeroing needs to be done *before* reading pickup info
643           and the pickup call might or might not happen in any
644           particular run
645      - this needs an overhaul for R2
646    o cleanup verification/*/code/GMREDI_OPTIONS.h
647    o cleanup testreport
648    
649    checkpoint51o_post
650    o bringing AD-related verif's up to date with genmake2

660        change rho -> rho-rhoConst
661      - replace call find_rho to find_rhonum
662    o initialisation of rFlx extended to full array (required by TAF)
663      and shifted to thermodynamics
664    o removed PTRACERS.h in ptracers routine

684         global_ocean.cs32x15, and global_with_exf)
685    o added surface flux output variables to TIMEAVE_STATVARS
686    
687    checkpoint51n_pre
688    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

712       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
713    
714    checkpoint51k_post
715    o change default to: useNHMTerms=.FALSE.

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

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

883     o new fn in pkg/monitor to stop model if solution grows too big
884     o removed lots of single quotes from comments
885    
886    checkpoint50e_post
887    o make KPP work with PTRACERS
888     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
889       nearly a copy of kpp_transport_s
890     - there is no analogue to SurfaceTendencyS, so I have to use
891       gPtr(of the surface layer) instead
892    o add a new platform SunFire+mpi (SunFire 15000) to genmake
893    checkpoint50e_pre
894    
895    checkpoint50d_post
896    o change kpp output from multiple-record state files to single-record state
897      files analogous to write_state.F
898    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
899      analogous to the cg2d-related output.
900    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
901      so that writing to internal file fn (with length 512) fails.
902    checkpoint50d_pre
903    
904    checkpoint50c_post
905    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
906    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
907    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
908    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
909    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
910    
911    checkpoint50c_pre
912    Merging from release1_p13:
913    o bug fix for pkg/seaice dynamic solver
914    o Added SEAICE_initialHEFF to pkg/seaice
915    
916    checkpoint50b_post
917    o store u*,v* in gU,V instead of in guNm1,gvNm1
918    o in order to put the momForcing out of the Adams-Bashforth:
919      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
920      to timestep.F
921    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
922    o re-generate output for highly sensitive test-exp:
923       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
924    
925    checkpoint50b_pre
926    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
927    o corrected CPP option mismatch in exf_Bulk... functions for case
928      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
929    
930    checkpoint50a_post
931    o Bug fix for merging between c50 and KPP.
932      ikey was passed from thermodynamics to kpp_calc via
933      common block rather than being recomputed in kpp_calc,
934      in contradiction with new key itdkey.
935      New key ikppkey created, and tamc.h headers updated.
936    
937    checkpoint50
938    - 2nd step of merge with ecco-branch:
939      merge changes in ecco-branch back into main trunk
940    - bug fix in find_alpha
941    - more storing in gmredi_calc_tensor.F, kpp_routines.F
942    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
943    - merged some sliced AD support routines
944    
945    checkpoint49
946    merged from ecco-branch:
947    o exf:
948      - Enable initialisation of forcing fields to constant
949        (runtime) values.
950      - in exf_getffields.F
951        Reduce i-/j-loop to interior domain, discarding overlaps.
952        That also fixes wrong TAF-key computations for key_1, key_2
953        with bulf formulae.
954      - exf_init.F modify #ifdef for exf_init_evap
955      - exf_getffieldrec.F, ctrl_getrec.F
956        The following INT-usages are not safe:
957          fldsecs  = int(fldsecs/fldperiod)*fldperiod
958          fldcount = int(fldsecs/fldperiod) + 1
959        and were modified.
960    o autodiff: checkpoint_lev...
961      - updated storing for bulk formulae (some arrays were missing)
962      - added state for seaice package
963      - synchronized with main branch
964    o DIVA:
965      Modif.s in
966      - the_main_loop.F
967      - the_model_main.F
968      and added cost_final_restore.F cost_final_store.F
969      o With these changes, it is possible to fully separate
970        the first forward run to compute the cost function (mdthe_main_loop)
971        and adjoint runs over individual DIVA intervals (adthe_main_loop)
972        into separate model executions.
973        This enables better tuning of DIVA to given queue sizes.
974      o Loss of cost function value in consecutive DIVA runs is
975        fixed by storing to 'costfinal' file.
976      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
977        beginning/end of adjoint integration is accounted for.
978      The current changes apply to TAF-1.4.26.
979      TAF has one remaining bug, requiring one manual change
980      (see MITgcm manual).
981    o cal: synchronized between MAIN and ecco-branch
982    
983    checkpoint48i_post
984    o Changes to restore differentiability of code w.r.t. previous tag
985      (mostly adding new routines to make list and replacing
986      pressure by totPhiHyd).
987    o Updated and merged grdchk package
988      - has both ADM and TLM checks
989      - works for single- and multi-proc.
990      - output cleaned
991      - worked successfully for parallel DIVA
992    o genmake:
993      - Adding -platform=SP4
994      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
995    o Modif. for DIVA:
996      ctrl_unpack should not be called in intermediate DIVA interval.
997      (similar thing would apply for active files such as
998      tbar, sbar, psbar, which should not be reinitialised;
999      only relevant for ecco-branch)
1000    
1001    checkpoint48h_post
1002    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1003    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1004    o Added SEAICE_initialHEFF to pkg/seaice
1005    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1006    
1007    checkpoint48g_post
1008    --- EOS:
1009    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1010      store total Potential in totPhyHyd for diagnostics & EOS.
1011    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1012    --- Pressure/geopotential gradient:
1013    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1014    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1015      ( changes results of global_ocean_pressure )
1016    o NLFS + z-coord.: add eta*Rho' contribution.
1017    o accurate phiHyd when using interface-W at the middle between 2 centers
1018     ( changes results of ideal_2D_oce )
1019    o includes r* 2nd term in potential gradient.
1020    
1021    checkpoint48f_post
1022    Merging from release1_p12:
1023    o Modifications for using pkg/exf with pkg/seaice
1024      - improved description of the various forcing configurations

1026      - units/sign fix for evap computation in exf_getffields.F
1027      - updated verification/global_with_exf/results/output.txt
1028    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1029      (SBO) core products, including oceanic mass, center-of-mass,
1030      angular, and bottom pressure (see pkg/sbo/README.sbo).
1031    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1032      to avoid negative values in shallow regions.
1033      - updated verification/natl_box/results/output.txt
1034      - updated verification/lab_sea/results/output.txt
1035    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1036    o Added useSingleCpuIO option (see PARAMS.h).
1037    o Updated useSingleCpuIO option in mdsio_writefield.F to
1038      work with multi-field files, e.g., for single-file pickup.
1039    o pkg/seaice:
1040      - bug fix in growth.F: QNET for no shortwave case
1041      - added HeffFile for specifying initial sea-ice thickness
1042      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1043    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1044      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1045    o pkg/seaice:
1046      - adjoint-friendly modifications
1047      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1048    
1049    checkpoint48e_post
1050    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1051    o dynamics: change definition of computational domain & adapt mom_fluxform
1052      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1053    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1054        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1055        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1056        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1057        inverted_barometer solid-body.cs-32x32x1
1058      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1059    
1060    checkpoint48d_post
1061    o in preparation for r*:
1062     a) use pre-computed gradient of hydrostatic potential:
1063        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1064     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1065        => affects results of glob_oce_pressure (different truncation error)  
1066      update output.txt of ideal_2D_oce & global_ocean_pressure
1067    
1068    checkpoint48d_pre
1069    o in preparation for r*:
1070      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1071      pass the 2 comp. of the grad. as arguments to momentum S/R.
1072      but for the moment, only used if it does not change the results.
1073    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1074    
1075    checkpoint48c_post
1076    Modifications in treatment of initial flux forcing controls
1077    to avoid extra storing of flux fields.
1078    
1079    checkpoint48c_pre
1080    o Added tidal_basin_2d experiment (currently 1D!)
1081    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1082    
1083    checkpoint48b_post
1084    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1085     (modification to pressure gradient not yet implemented)
1086    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1087      (for U & V) that are used for vertical advection of momentum.
1088    
1089    checkpoint48a_post
1090    o In preparation for r*, use temp. array to compute vertical transport
1091       in flux-form momentum pkg. => change results of few test-exp.
1092      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1093                        lab_sea, natl_box & plume_on_slope
1094    
1095    checkpoint48
1096    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1097    
1098    checkpoint47j_post
1099    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1100    o moved adexch from forward_step to addummy_in_stepping
1101    o added exch in ctrl_map_...
1102    o aveFreq.=0. at end of cost_final to avoid overwrite in
1103      reverse checkpointing loop
1104    o Yet more changes in gmredi:
1105      * adgmredi_calc_tensor
1106        avoiding all recomputation of gmredi_slope_limit
1107      * adgmredi_x/y/rtransport
1108        added flag for excessive storing to avoid recomp. of
1109        u/v/rtans, dTdx/y/z
1110        -> this is not really necessary and very memory-consuming
1111      * adgmredi_slope_psi:
1112        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1113      * gmredi_slope_limit
1114        re-activated full calculation of taperfct for case 'ac02'
1115    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1116    
1117    checkpoint47i_post
1118    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1119    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1120      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1121    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1122    o gmredi: fix few bugs.
1123    
1124    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1125    This will be a good checkpoint to plug into the ecco-branch.
1126    o few modif.'s to get latest version adjointed
1127      (mainly kick out code in ini_linear_phisurf)
1128    o modif's to run adjoint with exactConserv
1129    o case GM_BOLUS_ADVEC should be cleaned
1130      S/R gmredi_slope_psi should be cleaned
1131    o verification/carbon now has exactConserv=.TRUE.
1132    
1133    checkpoint47g_post
1134    o time-average AIM output: becomes independent from statvars time-average
1135      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1136    o After TAF bug fix:
1137      Tested adjoint of gmredi package.
1138      Tests were done with checkpoint47 rather than with latest
1139      checkpoint47f_post since the latter is broken for the adjoint
1140      verification/carbon/ contains both ADM and TLM gradient checks.
1141    Here they are, before they get changed/lost/stolen.
1142    Mostly modif.'s to fix numerical sensitivities.
1143    Gradient checks OK for
1144    - GM_taper_scheme:
1145      * clipping
1146      * ac02
1147      * linear
1148      * glw91
1149      * dm95
1150      * ldd97
1151    - GMREDI_OPTIONS:
1152      * GM_VISBECK_VARIABLE_K
1153      * GM_NON_UNITY_DIAGONAL
1154      * GM_EXTRA_DIAGONAL
1155      * GM_BOLUS_ADVEC
1156    in conjunction with data.gmredi parameters to be checked in
1157    in a few minutes under verification/carbon/code/
1158    
1159    checkpoint47f_post
1160    Merging from release1_p10:
1161    o modifications for using pkg/exf with pkg/seaice
1162      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1163        and SEAICE_EXTERNAL_FLUXES
1164      - pkg/exf CPP options EXF_READ_EVAP and
1165        EXF_NO_BULK_COMPUTATIONS
1166      - usage examples are Experiments 8 and 9 in
1167        verification/lab_sea/README
1168      - verification/lab_sea default experiment now uses
1169        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1170    
1171    checkpoint47e_post
1172    o created a tag prior to creating a branch
1173    
1174    checkpoint47d_post
1175    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1176      at the bottom boundary had an erroneous half slip boundary condition
1177    o added bottom drag and no slip boundary condition capabilities to
1178      oceanic pressure coordinates code
1179    o added new verification experiment global_ocean_pressure, this experiment is
1180      also described in the tutorial section of the manual
1181    checkpoint47d_pre
1182    
1183    checkpoint47c_post
1184    o Added a verification experiment for a global cubed-sphere ocean run
1185      -  verification/global_ocean.cubed32x32x30
1186      -  uses pkg/therm_seaice and pkg/bulk_forcing
1187    
1188    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1189    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1190      when using P-coordinate; only implemented for atmospheric config.
1191    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1192      NOTES: requires option NONLIN_FRSURF to be "#define".
1193    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1194    
1195    checkpoint47b_post
1196    Merging from release1_p9:
1197    o pkg/seaice
1198      - removed GOTO's and added taf directives
1199      - double precision constants to reduce the g77 (Linux)
1200        to F77 (SGI) differences reported in release1_p8
1201    o tools/genmake
1202      - added SGI options
1203    o verification/testscript
1204      - updated to that of checkpoint47a_post
1205    o verification/global_ocean.90x40x15/input/eedata
1206      - modified for SGI f77 compatibility
1207    o verification/lab_sea
1208      - added description of sea-ice model
1209      - added missing matlab routines
1210      - added test of thermodynamics parallelization
1211    
1212    checkpoint47a_post
1213    o new pkg: aim_v23
1214     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1215       for now, keep the same surface forcing as before.
1216     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1217     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1218     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1219    o add diagnostic of surface correction term in monitor output
1220    
1221    o bulk_force and therm_seaice
1222    - Two packages:  bulk_force (Bulk forcing)
1223      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1224    - Earlier integration from Stephaine Dutkiewicz
1225      and Patrick Heimbach.
1226    - Two ifdef statements for compile time,
1227       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1228    
1229    checkpoint47
1230    differentiable version of checkpoint46n_post
1231    o bug fix in quasihydrostaticterms
1232    o * "clean" adjoint code (in terms of extensive recomputations)
1233        can now be obtained for all GMREDI options (i.e. for
1234        - GM_VISBECK_VARIABLE_K
1235        - GM_NON_UNITY_DIAGONAL
1236        - GM_EXTRA_DIAGONAL
1237        - GM_BOLUS_ADVEC )
1238      * However, wrong gradient check problem remains unsolved.
1239      * New CPP options have been introduced for different
1240        tapering schemes
1241    o external_fields_load now part of differentiation list
1242    o pressure needs multiple storing;
1243      would be nice to have store_pressure at beginning or
1244      end of forward_step, e.g. by having phiHyd global (5-dim.)
1245      (NB: pressure is needed for certain cases in find_rho,
1246      which is also invoked through convective_adjustment).
1247    o recomputations in find_rho for cases
1248     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1249    o #define ATMOSPHERIC_LOADING should be differentiable
1250    o ini_forcing shifted to begining of initialise_varia
1251    o Incorporating QNVS line search routines into MITgcm
1252      (this is separate code, and therefore not under pkg)
1253      lsopt/, optim/
1254    o Updated verification/carbon/
1255      - #define GM_VISBECK_VARIABLE_K
1256      - GM_taper_scheme    = 'ldd97'    
1257    
1258    checkpoint46n_post
1259    Merging from release1_p8:
1260    o verification/natl_box:
1261      updating new external_fields_load routine
1262    o New package: pkg/seaice
1263      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1264      The sea-ice code is based on Hibler (1979-1980).
1265      Two sea-ice dynamic solvers, ADI and LSR, are included.
1266      In addition to computing prognostic sea-ice variables and diagnosing
1267      the forcing/external data fields that drive the ocean model,
1268      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1269      The implied surface heat flux is then stored in variable
1270      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1271      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1272      non-local transport term.  Because this call precedes model
1273      thermodynamics, temperature under sea-ice may not be "exactly" at
1274      the freezing point by the time theta is dumped or time-averaged.
1275      N.B.: fairly large differences in accuracy occur across
1276            different platforms/compilers; comparison between
1277            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1278            generated output gives:
1279       T           S           U           V
1280      C D M    c        m  s        m  s        m  s        m  s

1284    
1285      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1286    o GAD:
1287      - generated new common blocks to account for call of
1288        same gad routines with differing traceridentities
1289        (needed to modify tracerIdentity indices in GAD.h)
1290      - generated separate common blocks for case useCubedSphereExchange
1291        (Department of Futurology)
1292      - parameter lists to gmredi_?transport: added tracerIdentity
1293      - added new key indices to tamc.h
1294    o external_fields_load:
1295      - added this routine to TAF list
1296      - needed to make some common blocks global and additional storing
1297        along the same lines as exf package (checkpoint_lev?_directives.h)
1298    o exf:
1299      updated external forcing package
1300      - bug fixes carried over from ecco-branch
1301        (missing OBCS_OPTIONS.h in two routines)
1302      - enable easy to use "no forcing".
1303      - added exf I/O for atmospheric loading
1304      - added exf I/O for runoff data
1305      - transfered scaling between exf <-> MITgcm to exf namelist
1306    o Adding new verification experiment global_with_exf.
1307      This verification experiment is almost identical to the
1308      global_ocean.90x40x15 experiment, except that it uses
1309      the exf (and cal) package instead of the
1310      external_fields_load routine (cf README file).
1311    
1312    checkpoint46m_post
1313    o modified testscript to return -- when there are no lines of "%MON" output
1314    o added new flag "quasiHydrostatic" for QH mode
1315      and new routine quasihydrostaticterms()
1316    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1317      New routine: mom_u_coriolis_nh()
1318    o fixed sign of non-hydrostatic metric terms in u and v equations.
1319      Depend on correct sign of gravitySign.
1320    o added work.pc* to .cvsignore in aim directories using ifc
1321    o introduced flag for controllin non-hydrostatic metric terms
1322    o removed gravitySign from PARM04
1323    o switched to g77/ifc from pgf77 in aim experiments
1324    
1325    checkpoint46l_post
1326    o made convective adjustment work with pressure coordinates:
1327     - changed the direction of k-loop in convective_adjustment.F for the
1328       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1329     - adjusted the reference pressure k-index in convective_adjustment.F
1330     - adjusted the convection condition in convect.F (in analogy to
1331       calc_ivdc.F)
1332     - convective_adjustment no longer computes anything on the halos
1333     - removed the warnings about negative salinity from find_rho.F and
1334       find_alpha.F; instead the new routine look_for_neg_salinity, called
1335       at the beginning of find_rho, find_alpha, and find_beta, does a
1336       check of the entire slice, if CPP-option
1337       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1338    checkpoint46l_pre
1339    
1340    checkpoint46k_post
1341    o fixed the verification/global_ocean.90x40x15 experiment:
1342     - new bathymetry (the world according to A., JMC, and M.)
1343     - new initial fields and forcing fields (*.bin files)
1344     - new POLY3.COEFFS (for the next release one should switch to a full
1345       equation of state: JMD95P or MDJWF)
1346     - fixed several errors and redundancies in the data file
1347     - experiment uses looped cells
1348     - added matlab directory with diagnostic scripts for plotting of output
1349    
1350    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1351     - read AIM physics parameters from a file (data.aimphys)
1352     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1353    
1354    checkpoint46j_post
1355    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1356    o move wVel computation at the end of the time step, in S/R integr_continuity
1357    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1358    o update timeave pkg for wVel diagnostic.
1359    checkpoint46j_pre
1360    
1361    checkpoint46i_post
1362    o Clean up AIM package (and keep the results unchanged):
1363      include CPP_OPTION and use IMPLICT NONE in all routines ;
1364      declare all the variables _RL ; use _d 0 for all numerical constants.
1365      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1366    
1367    checkpoint46h_post
1368    o cleaned up the use of rhoNil and rhoConst.
1369      - rhoNil should only appear in the LINEAR equation of state, everywhere
1370        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1371        and the dynamical equations are all divided by rhoConst
1372    o introduced new parameter rhoConstFresh, a reference density of fresh
1373      water, to remove the fresh water flux's dependence on rhoNil. The default
1374      value is 999.8 kg/m^3
1375    o cleanup up external_forcing.F and external_forcing_surf.F
1376      - can now be used by both OCEANIC and OCEANICP
1377    checkpoint46h_pre
1378    
1379     Added code to convert surface volume flux (fresh water) into
1380     a mass flux when using P coordinates in the ocean (OCEANICP).
1381     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1382    
1383    checkpoint46g_post
1384    o Include a new diagnostic variable phiHydLow for the ocean model
1385      - in z-coordinates, it is the bottom pressure anomaly
1386      - in p-coordinates, it is the sea surface elevation
1387      - in both cases, these variable have global drift, reflecting the mass
1388        drift in z-coordinates and the volume drift in p-coordinates
1389      - included time averaging for phiHydLow, be aware of the drift!
1390    o depth-dependent computation of Bo_surf for pressure coordinates
1391      in the ocean (buoyancyRelation='OCEANICP')
1392      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1393        Theta, Salinity, and Pressure in the parameter list. This routine is
1394        presently contained in find_rho.F. This routine does not give the
1395        correct density for 'POLY3', which would be a z-dependent reference
1396        density.
1397    o cleaned up find_rho
1398      - removed obsolete 'eqn' from the parameter list.
1399    o added two new verification experiments: gop and goz
1400      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1401    checkpoint46g_pre
1402    
1403    checkpoint46f_post
1404    o Enable tangent linear (forward mode) gradient checks:
1405      - extended active file handling to g_... files
1406      - added TANGENT_SIMULATION to theSimulationMode
1407      - extended grdchk package accordingly
1408    o added tangent linear setup in verification/carbon/code_ftl
1409    o added adjoint setup in verification/front_relax/code_ad
1410    
1411    checkpoint46e_post
1412    o Added new equation of state -> MDJWF
1413      - EOS of McDougall et al., 2002, JAOT, submitted
1414      - caveat: the equation of state is only valid for a smaller (more
1415        realistic?) range of values than JMD95P/Z and UNESCO
1416      - added masks to the calculation of pressure in store_pressure
1417      - added more check values for density in check_eos (ini_eos.F), some of
1418        the old check values are out of the range of the MDJWF-eos, so don't
1419        expect perfect matches for those
1420    checkpoint46e_pre
1421    
1422    checkpoint46d_post
1423    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1424      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1425      case of pressure coordinates. eosType='JMD95Z' in
1426      combination with buoyancyRelation='OCEANICP' now causes an error.
1427    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1428      in find_alpha/beta.
1429    checkpoint46d_pre
1430    
1431    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1432      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1433    
1434    checkpoint46c_post
1435    o Changes necessary for ocean in p-coordinates
1436     -  Added new buoyancy relation = 'OCEANICP'
1437     -  Added new parameters = gravitySign (this used to be contained inside
1438        the factor dRdZ which I added when we first switched to R coordinates).
1439     X GM/Redi is not compatible (yet)
1440     X bottom drag and no-slip need to be debugged.
1441    checkpoint46c_pre
1442    
1443    checkpoint46b_post
1444    o Added new equation of state -> JMD95Z and JMD95P
1445      - EOS of Jackett and McDougall, 1995, JAOT
1446      - moved all EOS parameters into EOS.h
1447      - new routines ini_eos.F, store_pressure.F
1448    o Added UNESCO EOS, but not recommended because it requires
1449      in-situ temperature (see JMD95)
1450    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1451      unesco.f to be used with POLY3
1452    checkpoint46b_pre
1453    
1454    checkpoint46a_post
1455    o Added (atmospheric) pressure loading
1456      - new field in FFIELDS.h, etc...
1457      - new cpp flag ATMOSPHERIC_LOADING
1458    o Changed hFacC to _hFacC in calc_phi_hyd.F
1459    o Added SHORTWAVE_HEATING to some files for consistency
1460    checkpoint46a_pre
1461    
1462    checkpoint46
1463    further merges from release1_p5
1464    o new ctrl package
1465      - adopted from ECCO environment to enable optimization
1466      - added Eliassen Palm fluxes to controls
1467    o added Eliassen Palm flux controls to gradient check package
1468    o cost package
1469      - Compatible with new ctrl package
1470      - added Eliassen Palm cost hooks
1471      - modif's of existing cost functions
1472    o Adjoint-related bug fixes in kpp:
1473      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1474      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1475    o autodiff package
1476      - flow directives:
1477        + new for S/R do_the_model_io
1478        + enhanced for S/R checkpoint
1479        + new gmredi.flow
1480      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1481        disable adcommon.h/g_common.h by default.
1482      - fixed problem for adjoint of global_max
1483    o modified verification/carbon/
1484    o New setup for adjoint of global_ocean
1485    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1486    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1487    o incorporated hooks for sponge layer code (external_forcing.F)
1488    
1489    checkpoint45d_post
1490    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1491    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1492      (affects plume_on_slope "cg2d" output)
1493    o add new parameter deltaTfreesurf for free-surface time stepping
1494    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1495    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1496    o change phiMin in exp1 (to agree with documentation)
1497    o add new flags:
1498     - T,S forcing inside/outside Adams-Bashforth
1499     - turn off temp,salt advection and/or forcing
1500     - for each tracer, define internal flag for multiDimAdvection & A-B
1501    o monitor: change definition of KE to check conservation of Energy
1502    
1503    checkpoint45c_post
1504    o Removed f90 comments ("!")
1505    o Modified initialisations to enable exf package for MITgcm
1506      (without invoking ECCO_PACKAGE).
1507    o modifications to gradient check package (Martin Losch)
1508      - enable centered differences
1509      - modified format of standard output
1510    
1511    checkpoint45b_post
1512    o cleaned exchange calls in cg2d
1513    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1514    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1515      to configure barotropic setup (Martin Losch)
1516    o moved some initialisations within bi,bj loop in dynamics
1517      (TAF flow dependency)
1518    o in initialise_varia, moved call packages_init_variables
1519      before convective_adjustment_init
1520      (corresponding adjustment of TAF tape initialisation).
1521    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1522    
1523    checkpoint45a_post
1524    o compute Rho over the whole domain (extend iMin,jMin indices)
1525    o specific exchange for X-slice domain (case Ny=1)
1526    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1527    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1528    
1529    checkpoint44h_post = checkpoint45
1530    o Fix to restore differentiability:
1531      place at which packages_init_variables is called in
1532      initialise_varia is crucial for reverse control flow.
1533    o modifications in GMRedi to enable stable adjoint
1534      (corresponding modif's in thermodynamics, dynamics)
1535    o added missing hook for sponge layer code in external_forcing
1536    o modified test cost functions
1537    o storing in gad_advection (plus removal of write(0,*)!
1538    o missing headers TR1.h added in convective_adjustment routines
1539    o errorMessageUnit set non-equal zero in eeboot
1540      (conflict on some platforms, e.g. IBM SP3)
1541    o modified carbon verif.
1542    
1543    checkpoint44h_pre
1544    o vertical grid option: allow to put the Interface at the middle between
1545      2 cell-centers ; replace delZ in pkg/kpp by drF.
1546    o GM Advective form: Tracers are advected using the residual transport (=
1547      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1548    
1549    checkpoint44g_post
1550    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1551      results) ; ifdef missing in thermodynamics.F
1552    
1553    checkpoint44f_pre,checkpoint44f_post
1554    o added PTRACERS package
1555      This allows an arbitrary number of passive tracers to be integrated
1556      forward simultaneously with the dynamicaly model.
1557      + Implemented so far:
1558        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1559        - I/O and checkpointing
1560        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1561      + Not implemented so far:
1562        - KPP
1563        - OBCS
1564      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1565        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1566        line in data.pkg.
1567      + This package is disabled by default since it increases storage.
1568    
1569    
1570    o testscript: added -cleanup option
1571    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1572                 b) enable to filter 2D fields.
1573    
1574    checkpoint44e_pre,post
1575    o re-wrote convective adjustment to use pre-calculated weights
1576      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1577      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1578      Original calls to convect() still in place.
1579    
1580    chkpt44d_pre,post
1581    o added missing EXCLUDE_MONITOR flags
1582    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1583      (incompatible typ in MIN/MAX expressions caused problems
1584      on IBM SP3)
1585    o in genmake added variable MAKEDEPEND
1586      plus resetting for case SunOS
1587    o added timer_stats.c routine for IBM SP3
1588    o removed variables in dynamics
1589    !!! I forgot to create tag chkpt44d_pre !!!
1590    !!! But chkpt44d_pre = chkpt44c_post    !!!
1591    
1592    o real fresh water flux implemented with non-linear free-surface.
1593    
1594    chkpt44c_pre,post
1595    o few fix (mask in shap_s2, EmPmR in external_field_load,
1596      USE_NATURAL_BCS in solve_for_P);
1597    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P

1628    checkpoint42
1629      Fixed AD-related problems:
1630    o Store directives up-to-date with re-arranged Adams-Bashforth
1631      (mainly thermodynamics.F)
1632    o New store directives for multi-dim. advection schemes
1633      * new CPP flag ALLOW_MULTI_DIM_ADVECTION

1662      
1663    checkpoint40pre8
1664    o new package rw/
1665      Added method for dumping intermediate local arrays:
1666      mdsio_writetile - same as mdsio_writefield except works from inside
1667                        bi,bj loop
1668      mdsio_writelocal - same as mdsio_writetile except works for local
1669                         arrays
1670      write_local_r? - higher-level wrapper for mdsio_writelocal
1671      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1672      Example given at end of mom_vecinv.F that dumps some local arrays.
1673    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1674      control flux-form versus vector invariant code.
1675      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1676      or genmake -DISABLE ...
1677    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1678      (additional storing is now needed for case vecinv;
1679      currently nothing implemented to switch this storing off
1680      in case fluxform is used since no CPP flag available).
1681    
1682    checkpoint40pre7
1683    o bug fix in dynamics.F
1684      calc_viscosity called before k=1,Nr loop.

1694    o Added diffkr, kapgm to control variables
1695    o bug fix in gmredi_slope_limit for ldd97
1696    
1697    checkpoint40pre5
1698    o proper initialization of Adams-Bashforth time stepping
1699      + uses forward step for very first step of model (iter=0)
1700    o re-generated *all* output since almost all output is modified by this
1701      change (sorry but we've been putting this one off for about 2 years)
1702      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1703        *not* regenerated since they are already out of date and I don't
1704        want to create the impression that they are suddenly working.
1705    o removed KAP stuff for DEC's
1706    o modified/added many .cvsignore files in */code and */input
1707    o added new expt "solid-body.cs-32x32x1"
1708      + this uses an alternative form of ini_curvilinear_grid.F which
1709        is not necessarily any better than the current one...
1710    
1711    checkpoint40pre4
1712    o added re-initialisations of utrans,vtrans,rtrans in
1713      calc_common_factors which are crucial for TAF.

1723    
1724    checkpoint40pre2
1725    o Updated to latest branch of AJA, JMC
1726    o Added gradient check package
1727    o Added routines for passive tracer handling
1728    o Added carbon sequestration sensitivity experiment
1729    
1730    checkpoint39
1731     o Modifications and fixes to support TAMC
1732       (mainly missing or wrong directives)
1733     o Corrected common blocks when fooling TAMC to produce adjoint I/O
1734       in addummy_in_stepping
1735     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1736     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1737     o Included following packages:
1738       cal: calendar
1739       exf: external forcing
1740       ecco: essential routines to control use of cal, exf
1741             (NB: this is not the full ECCO environment)
1742     o disabled some packages by default in genmake
1743    
1744    checkpoint38
1745     o see notes_c37_adj.txt
1746     o corrected wrong layer index in external_forcing_t
1747     o replaced the_main_loop/forward_step by the_main_loop
1748     o removed forceoutput from write_state
1749       (replaced criteria for initial/final state)
1750     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1751    
1752    checkpoint37
1753     o mdsio.F routine split and packaged in pkg/mdsio
1754       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1755        used unless genmake -disable=mdsio)
1756     o allow a more precise surface-geopotential gradient for the atmosphere
1757       taking into account the change in space of Alpha (=1/rho) at the surface.
1758     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1759       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1760     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1761       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1762       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1763     o Time-Average diagnostics defined as a pseudo package "timeave".
1764     o pickup files : old pickup (before c35) did not work with new code (c35
1765       and after) unless activating 2 commented lines in initialise-varia.
1766     o Non-Hydrostatic pickup file Pb fixed.
1767     o bug with Rigid-lid version (since c35) fixed.  
1768    
1769  checkpoint36  checkpoint36
1770   o implement Crank-Nirotropic time-stepping   o implement Crank-Nickelson barotropic time-stepping
1771   o recover Time-Average diagnostics   o recover Time-Average diagnostics
1772   o fix Pb in checkpoint (PR#19)   o fix Pb in checkpoint (PR#19)
