4      ==============================      ==============================
5    
6    o GCHEM:
7      - move call to GCHEM_FORCING_SEP, so that it is now called before
8        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
9      - introduced a useGCHEM runtime flag and applied it everywhere.
10    o small cleaning of exch2: remove files that are also in eesupp/src
11    
12    checkpoint56
13    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
14    o mnc: cleanup "full" files--fixes out-of-memory problem
15    o ECCO-GODAE
16      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
17      * fully merged and updated from SIO code
18        windstress sign change affects
19        - exf_inscal_[u/v]stress
20        - sign of xx_tau[u/v] adjustments
21        - signs in cost_scat
22      * ctrl_get_gen: avoid update of tau[u/v] for first few days
23      * natl_box_adjoint updated and compressed
24      * 2-level checkpoint switch added
25        (tested in EXP. 1 of natl_box_adjoint)
26      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
27    o SVD
28      * first complete, non-hacked version for SVD calculations
29      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
30        performed via direct access files admtlm_vector.it????
31        (via ctrl_[un]pack)
32      * optimcycle is used for ARPACK iteration counter
33        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
34      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
35        and add linear transforms where necessary
36      * controls are initial/final SST, SSS (can be extended; need to check
37        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
38    o mdsio: filename info to both stderr, stdout
39    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
40      from sign change
41    
42    checkpoint55j_post
43    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
44      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
45    o add consistent build directories and .cvsignore files to verification
46    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
47    o make all subroutines 30 or less characters in length for certain older
48      compilers to work (a thorough search only turns up two routines in
49      pkg/ptracers)
50    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
51      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
52    
53    checkpoint55i_post
54    o change arrays for total vertical diffusivity (2.D if explicit,
55      3.D if implicit) ; each ptracer uses its own background value.
56    o added mnc/NetCDF output capability to ocn_compon_interf
57      - added bits to verification/cpl_aim+ocn so that it can run on
58        ITRDA and other clusters without the mpirun "-wd" option
59    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
60      configuration
61    o give MNC the ability to create additional files rather than
62      exceeding a specified file size limit "MNC_MAX_FILESIZE"
63      - the default is just less than 2GB which is a practical limit
64        on many systems
65    o Compute the non-local term using either KPP vertical diffusivity (=default)
66       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
67    
68    checkpoint55h_post
69    o add verification test "vermix"
70    o remove all the *_ioinc flags and replace with the single global
71      outputTypesInclusive flag
72    o allow to set a vertical profile of vertical diffusivity for T & S
73    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
74    o useMNC moved from data.mnc to data.pkg
75    
76    checkpoint55g_post
77    o Renaming carbon AD experiments to comply with testreport conventions
78    o Updating adjoint of Held-Suarez hs94.1x64x5
79    o Fixing directives for non-ECCO forward_step, after ECCO directives
80      have been fixed to avoid recomp. of do_oceanic_phys
81      Works well for global_ocean.90x40x15,
82      but recomp. issue remains for carbon
83    o Updating adjoint output for natl_box_adjoint after
84      pkg/ecco has been modified (see taga c55d_post)
85    
86    checkpoint55f_post
87    o rename to timeave_init_fixed
88    
89    checkpoint55e_post
90    o some delicate re-shuffle of store directives to avoid one
91      extra call of do_oceanic_physics
92      affects ecco_the_main_loop.F, do_oceanic_physics.F
93      checkpoint_lev1_directives.h
94    o NB: this may break global_ocean adjoint temporarily,
95      but it is clear how to fix it. Will do later, need this now.
96    
97    checkpoint55d_post
98    o ECCO specific cost function terms (up-to-date with 1x1 runs)
99    o ecco_cost_weights is modified to 1x1 runs
100    o modifs to allow observations to be read in as
101      single file or yearly files
102    o enable to read exf forcing fields as either
103      single file or yearly files (flag useExfYearlyFields)
104    checkpoint55d_pre
105    
106    o switch between 2-level and 3-level checkpointing
107    o add ability of MNC to write local and "partial" (eg. 2D slices where
108      the full 3D field is never actually stored) arrays to NetCDF files
109      with the correct (that is, the complete multi-dimensional) set of
110      array indicies
111      - used in mom_vecinv() to write the diagFreq output
112      - tested (demonstrated) in verification/aim.5l_cs
113    o further mnc-ification
114      - add verification/lab_sea to the list with mnc setups
115      - fix undefined mnc v-names in cd_code
116      - add kpp to mnc output (both snapshot and timeave)
117    o non-hydrostatic code
118      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
119        in calc_gw.F
120      - defaults to viscAh
121      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
122        friction or Leith) in non-hydrostatic mode, as long as there is
123        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
124    o pkg/cost
125      extend simple cost functions to treat time mean quantities
126      (T,U,V) via cost_accumulate_state from cost_tile
127    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
128        be 2 times larger than the minimum size the advection scheme requires.
129        now get a perfect conservation of salt in advect_cs test-exp (updated)
130    o GGL90 (Gaspar's TKE mixed layer)
131      - add horizontal diffusion of TKE, requires exchanges in
132        do_fields_blocking_exchanges, horizontal diffusivity is zero by
133        default. In OPA there is no horizontal diffusion of TKE but the
134        mixing coefficients are computed from a horizontal average of TKE of
135        6 points or so. I think that diffusion has a little more physical
136        justification.
137      - clean up ggl90_calc in the hope of reducing memory usage (this hope
138        was in vain)
139      - mask tke-variable in ggl90_init
140    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
141    o fix biharmonic diffusion on CS-grid.
142    o more obcs stuff
143      - added obcs_external_fields_load as an alternative to the EXF-pkg option
144        for reading boundary values. This routine is called from
145        obcs_prescribe_read
146      - updated obcs_check
147      - changed sponge layer relaxation parameter units for days to seconds
148      - turned off sponge layer by default
149      - changed argument list of OBCS_CALC to myTime+deltaTclock
150      - fixed about 35 bugs in obcs_external_fields_load
151    
152    checkpoint55c_post
153    o obcs stuff
154      - new runtime flags useOBCSprescribe, useOBCSbalance
155      - re-arranged obcs_calc
156      - moved exf_getobcs to obcs_prescibe_read
157        obcs_prescibe_read is called after ORLANSKI stuff
158        and independent of it (executable can contain all).
159      - updated obcs_check
160      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
161        These may be necessary only if tangential velocities are
162        prescribed at OB, not sure, needs testing.
163    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
164      which simplifies the calls and passes the ifc check-bounds test
165    
166    checkpoint55b_post
167    o add a 2D scalar, Z location, exchange_2 routine.
168    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
169      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
170      affects advect_cs results (for the wrong reason): update output.txt
171    o use a more standard discretization for biharmonic viscosity ;
172     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
173      affects results of dome set-up: update output.txt
174    o fix gad_advection.F (CubedSphere part), back to version 1.23
175    o fix bug in mom_vi_del2uv.F (CubedSphere part).
176    
177    checkpoint55a_post
178    o merged code to
179      * prescribe/read time-dependent open boundaries
180        (works in conjunction with exf, cal)
181      * sponge layer code for open boundaries
182      * each boundary N/S/E/W now has its own CPP option
183        (healthy for the adjoint)
184    
185    checkpoint55
186    o up-to-date adjoint of previous breaks
187      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
188      - global_ocean_ebm: adjoint still needs fix (TLM ok)
189      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
190      - carbon: * remove tr1-related adjoint verification
191                * add ptracer as control variable
192    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
193      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
194    
195    checkpoint54f_post
196    o in verification/carbin/ remove experiment related to
197      ALLOW_PASSIVE_TRACER (array tr1 etc)
198      code_ad/ input_ad/ results_ad
199    
200    o add two new packages
201      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
202        + subject to optimization (memory)
203      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
204        + subject to reordering (many GOTOs in the original code)
205        + so far opps is called for every (i,j) point, and then operates in
206          the vertical; one may want to reorder the scheme in order operate in
207          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
208          fields)
209    o overhaul of IO so that we now have flags for MDSIO and/or MNC
210      - all verification tests compile and run with linux_ia32_g77
211      - defaults are compatible with current input files--nothing
212        should change if you were not previously using MNC
213      - MNC output has been added in numerous places (eg. timeave)
214        but there are still a few writes not yet do-able with MNC
215        (this is in progress)
216      - flags now allow for either/or/both use of MDSIO and MNC and
217        documentation will soon follow
218      - numerous small formatting cleanups for ProTeX
219    o add version info (via BUILD_INFO.h) to MNC and stdout
220    
221    checkpoint54e_post
222    o add two new packages
223      - pp81 (Packanowski and Philander, 1981), Richardson number and
224        stratification dependent mixing
225      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
226      - these scheme operate in a similar manner as KPP (without ghat, of
227        course), however there is only one diffusivity that is used for both
228        temperature and salinity (and passive tracers)ç
229    o add offline package
230    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
231      provided by Stephanie Dutkiewicz
232    o genmake2: add ability to search for C compilers and cleanup test output
233      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
234    
235    checkpoint54d_post
236    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
237    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
238      leading to additional shift by 5 days each year of integration
239       (i.e. leading to considerable offset over the years)
240    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
241    o start with no AB and no initial filtering (staggerTimeStep):
242      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
243    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
244      (external loading & cpl import/export stay in forward_step.F)
245    o update coupling interface to work with new staggerTimeStep
246    o change MDSIO ptracers_pickup.
247    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
248    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
249    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
250    
251    checkpoint54c_post
252    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
253      this affects (truncation error) output.txt of test-exp:
254       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
255    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
256    o change Qnet to always be the net heat flux, (+upward).
257      affects (truncation error) output of natl_box exp.: updated
258    o define the max number of passive tracers in PTRACERS_SIZE.h
259    o start to test mnc routinely in exp0
260    o add sea-ice loading (sIceLoad) as a new forcing field.
261    
262    checkpoint54b_post
263    o add testreport "-j JOBS" option for parallel builds (tested and pretty
264       impressive on Altix and Opteron systems)
265    o diagnostics can now write NetCDF files through the mnc package
266    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
267    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
268    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
269      affects (truncation error) output of lab_sea & natl_box exp.: updated
270    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
271    
272    checkpoint54a_post
273    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
274    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
275    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
276    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
277      + internal_wave (shift in writing cg2d_ini_res)
278    checkpoint54a_pre
279    
280    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
281      - modified verification/lab_sea and natl_box_adjoint accordingly
282    
283    checkpoint54
284    checkpoint53g_post
285    o prepare splitting of thermodynamics: store convect.counter in common block
286    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
287      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
288    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
289    o new parameter "nShapS": allow to treat differently S from T (nShapT)
290    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
291    o restore adjointability
292    
293    checkpoint53f_post
294    o modifications that affect AIM experiment results (update output.txt):
295      - no advection of S at top interface Nr (pkg/generic_advdiff)
296      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
297    o AIM pkg:
298      - include stability function into surf.Flux derivative relative to Tsurf
299      - calculate clear-sky radiation & surface temp. change (for diagnostics)
300    
301    checkpoint53e_post
302    o merged cylindrical coord configuration
303    o added rotating_tank experiment
304    checkpoint53e_pre
305    
306    checkpoint53d_post
307    o faulks upgraded: re-generate output.txt that have changed:
308       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
309    o Added Bryan and Lewis, 1979, vertical diffusivity profile
310    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
311    o added Sadourny discretization of Coriolis
312      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
313      - re-enabled use of omega3 (useAbsVorticity)
314    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
315      vector-invariant equations
316      - note: does *NOT* yet use same variable visc. for no-slip BC's.
317    o recoded the lateral boundary conditions for non-hydrostatic w, this time
318      hopefully without new bugs
319      - still to do: biharmonic friction for non-hydrostatic w
320    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
321    o regenerated output for global_ocean_ebm (using -ieee)
322    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
323      of mom_common/
324      - simple re-arrangement of instructions within computing loop
325    checkpoint53d_pre
326    
327    checkpoint53c_post
328    o new version of coupler for AIM+thSIce and Ocean models
329     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
330     - land: change Evaporation of snow
331     - aim with thSIce: fix bug in snow-precip.
332    o changes to calc_gw.F
333     - bug fix for w^2 term near the bottom boundary
334     - (hopefully) improve the lateral slip boundary condtions for use with
335        partial/looped cells
336      - because the bug fix changes two verification experiments anyway (exp5
337        and plume on slope), change the lateral boundary condition from half slip
338        to the value of no_slip_sides
339    o ebm package wasnt quite up to the parallel task. Fixed that.
340    o Adjoint of EBM package + verification
341      * TLM OK
342      * ADM not sufficient accuracy yet (needs further testing)
343    
344    checkpoint53b_post
345    o Commiting new energy balance model to repository
346      * package is pkg/ebm
347      * verif. is verification/global_ocean_ebm
348      * references are in ebm_driver.F
349    C      * X. Wang, P. Stone and J. Marotzke, 1999:
350    C        Global thermohaline circulation. Part I:
351    C        Sensitivity to atmospheric moisture transport.
352    C        J. Climate 12(1), 71-82
353    C      * X. Wang, P. Stone and J. Marotzke, 1999:
354    C        Global thermohaline circulation. Part II:
355    C        Sensitivity with interactive transport.
356    C        J. Climate 12(1), 83-91
357    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
358    C        Destabilization of the thermohaline circulation
359    C        by atmospheric eddy transports.
360    C        J. Climate 7(12), 1870-1882
361    o Will need long integration testing.
362    checkpoint53b_pre
363    
364    o created pkg/mom_common in preparation for variable viscosity code
365    o renamed and split ini_mnc_io
366    o pkg/land: only liquid water can diffuse or run-off
367    o AIM using land: soil wetness availability account for snow
368    o added printMapIncludesZeros to EEPARMS namelist
369    
370    checkpoint53a_post
371    o restore TAMC compatiility for exf_constants.h
372      (no usage of _d in .h)
373    o Additional storing in KPP in an attempt to fix
374      TAMC problem with adjoint of KPP code.
375      (no success...)
376      Identical code works fine with TAF.
377    o Fixed verification/natl_box_adjoint experiments.
378      Initial conditions for Experiments 4 and 5 are now
379      set to "SEAICE_initialHEFF=0", which is more reasonable,
380      and hence gives results closer to that of Experiment 2.
381      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
382    
383    checkpoint53
384    o stable checkpoint with up to date adjoint
385      TLM tests only run for 1st grdchk at the moment. Its unclear if
386      this is a code problem or a problem with resetting code for g_
387      variables that is being autogenerated wrong.
388      Otherwise:
389       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
390       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
391         are both still in chaos following their security messes.
392    
393    checkpoint52n_post
394    o various build (mostly genmake2) changes including:
395      - ability to build/run more easily within Cygwin and MacOS X
396      - more complicated Makefiles with a stronger dependence on Gnu Make
397    o pkg/seaice modifications
398      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
399        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
400        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
401      - changed proxy for geostrophic velocity and updated
402        verification/lab_sea/results/* accordingly
403      - removed ADI dynamic solver from pkg/seaice
404      - replaced all occurrences of 1/CSTICE or 1/CSUICE
405        they caused a segmentation fault under certain circumstances
406      - removed unused field WATR
407    o bug fix in exf-package:
408      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
409         now reflect that.
410    o small fixes in the cal-package:
411      - set reference date to first of January for the 'model'-calendar
412      - failing of cal_CheckDate in cal_FullDate now actually results in a
413        warning
414    o small modifications in exf-package to increase flexibility:
415      - change climtempfreeze from a constant to a runtime parameter that
416        is specified in data.exf_clim (default = -1.9)
417      - introduce runtime parameter windstressmax (default = 2.0) that is
418        specified in data.exf
419    o fix in pkg/thsice:
420      - update Evap (Tsf changes) to be consistent with Latent heat flux
421      - maintain snow precipitation unchanged (even if Tsf >=0).
422     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
423    
424    checkpoint52m_post
425    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
426      this does not change any of the results, because myIter=0 in swfrac always
427      lead to jwtype=2 (the default anyway), but the call makes little sense
428      as a default
429    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
430    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
431      atmospheric model (AIM) to use it ; add a "slab ocean" component.
432    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
433    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
434    o extending useSingleCpuIO option to work with new exch2 I/O format
435      - old-style, missing-tile I/O is still accessible by defining CPP
436        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
437    o monitor package can write to NetCDF files and/or STDOUT
438    o fix re-definition bug in MNC_GRID_INIT_ALL()
439    o doc/api_reference added
440      - a framework for building an API Reference Manual using all
441        the "protex" comments embedded in the code
442      - see pkg/generic_advdiff, pkg/mnc for examples
443    o MNC:
444      - make myThid the last argument for all subroutines
445      - new default for the grid files: NO halos
446      - add useMNC and other run-time flags
447      - separate per-file-group handling of the unlimited dimension
448      - early initialization of MNC w/ flags read at the eeboot stage
449        and lookup tables set in initialize_fixed
450      - write all MNC output to a freshly-created directory
451    o thermodynamics sea-ice (thsice) is now tested with testreport.
452    o test exp. advect_cs: use the standard cs32 grid ; update output.
453    o Added functionality to grdchk:
454      pick global i,j,k position (or nearest wet) where to perform check.
455    
456    checkpoint52l_post
457    o new land formulation:
458      a) use ground enthalpy as prognostic variable to ensure exact
459         energy conservation.
460      b) account for water temperature and for latent heat of freezing
461         in all processes (rain, run-off, ground storage)
462      c) compute surface and ground temperature implicitly.
463    o aim_v23 modification for new land model:
464      a) Treat separately land / ocean / sea-ice surface fluxes
465         to allow implicit computation of land & sea-ice surface temp.
466      b) add snow precipitation.
467    checkpoint52l_pre
468    
469    o fix problem (when 1 tile is empty) in min/max monitor.
470    o fix bug in timeAve (u,vZetatave in common block)
471    o no restoring terms under ice for pkg/seaice
472    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
473    o bug fix for pkg/seaice pickups
474    o change MNC call locations and add coordinate attributes
475    o mask vorticity at the corner ; affects global_ocean.cs output
476    o fix ini_curvilinear_grid ; test CS experiments with mpi
477    o aim.5l_cs: modify sea-ice fraction input file ; update output
478    o exf: Adding simple range check routine for exf fields after read
479    
480    checkpoint52k_post
481    o removed top-level directory "diags"
482      - we migrated these functions to pkg/timeave a long time ago
483    o fixed bug introduced in pkg/monitor
484    o accuracy ctrlprec = 32 insuffient for gradient checks using
485      averaged fields (I/O via cost_averages)
486      -> use ctrl.h in active_file*.F to control I/O precision.
487    o paramter list of CALL ADTHE_MAIN_LOOP
488    o added initial do_the_model_io to ecco
489    o set all ...Freq to zero after cost_final
490      taveFreq, dumpFreq, pChkptFreq
491    o MAIN and ECCO differentiability restored
492    
493    checkpoint52j_post
494    o fix nchklev in tamc.h for global_ocean...
495    o Bringing flow and store directives up-to-date
496    o Really weird thing!
497      call do_the_model_io from the_main_loop with parameters
498      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
499      TAF places a faulty re-call of initialise_varia
500      after cost_final call which should not be there!
501    checkpoint52j_pre
502    
503    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
504      error messages
505    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
506    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
507      debug output
508    o modfied mdsio_writefield.F to handle non-global files under exch2
509    o update AIM Cubed-Sphere exp (aim.5l_cs):
510      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
511    o update AIM Equatorial Channel exp:
512      use standard aim_v23 pkg and change the SST fields to be more realistic.
513    o globalFile now works with exch2
514    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
515      mon_vort3.F to make exch2 friendly with >1 tile per cube face
516    o limit timeave output for hi-res integrations
517    
518    checkpoint52i_post
519    o removed CPP_EEOPTIONS.h from verification/*/code
520    o updated the tiling for global_ocean_pressure
521    checkpoint52i_pre
522    
523    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
524      the old pkg/aim).
525    
526    checkpoint52h_pre
527    o shortened offending lines in exch2_send_rx?.template
528    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
529    o genmake2: add build & execute test for NetCDF code
530    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
531      old grid files, moved CPP_EEMACROS.h to pkg/exch2
532    o added useSingleCPUIO flag to monitor.F and mon_out.F
533    o added temporary hack for sea-ice dynamics on the cube:
534      metric terms are ignored and it is assumed that
535      there is no sea-ice on cube faces 1, 2, 4, and 5.
536    
537    checkpoint52f_post
538    o added exch2 cube routines to pkg/exch2
539    o modified hs94.cs-32x32x5 to use it
540    o added new grid files to hs94.cs-32x32x5
541    checkpoint52f_pre
542    
543    checkpoint52e_post
544    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
545      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
546    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
547      to work with implicit vertical advection and AB ;
548    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
549    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
550     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
551    checkpoint52e_pre
552    
553    o fix bug in impldiff when Nr=1 or Nr=2.
554    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
555    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
556    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
557      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
558    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
559    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
560    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
561    
562    checkpoint52d_post
563    o re-tiled many expts to allow comparison in multi-processor mode
564      - updated output accordingly
565      - changed hs94.128x64x5 to use intial T from file rather than use the
566        random number generator
567    o add infrastructure in model routines for fizhi and gridalt packages
568    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
569    o changes to permit hi-res, cubed-sphere, configuration
570      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
571      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
572      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
573        of surface winds for the cube
574      (A verification experiment, based on global_ocean.cs32x15, but with
575       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
576       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
577       complete with example surface forcing files and matlab scripts to look
578       at the output and compare it with that of global_ocean.cs32x15.)
579    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
580       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
581       to conform to the common rule.
582    o check-in the first version of the coupler + interfaces for multi-components
583       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
584       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
585       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
586       - ocean and atmos. share the same horizontal grid (no interpolation).
587       - exchanges between component and coupler is done in forward_step
588    o new verification experiment, cpl_aim+ocn:
589       coupled ocean - AIM atmosphere on cs32 grid.
590    
591    checkpoint52d_pre
592    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
593    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
594    
595    checkpoint52c_post
596    o Fixing OPTIONS files for use of exf:
597      - ALLOW_ECCO not needed
598      - ECCO_CPPOPTIONS.h should not be included from
599        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
600        as has been the case in the past
601      - All cal/exf related options are currently set in
602        single header file. Should remain so until we
603        agree on a consistent new policy.
604    o Removed all CPP options for cal package.
605      cal has no more CPP options.
606    o modified STOREs in GAD_ADVECTION
607    o corrected key comp. for passkey
608    
609    checkpoint52b_post
610    o new version: "thsice" of thermodynamic sea-ice pkg:
611     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
612     - modify fluxes but do not change theta directly;
613     - light cleaning of bulk_force pkg (still needed with thsice).
614     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
615       + output_thsice.txt to test thsice & bulk_force pkgs.
616    o put back grid & coriolis monitor output.
617    checkpoint52b_pre
618    
619    o call "do_the_model_io" at the beginning (=> dump initial state)
620    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
621    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
622      (need info on NUMBER_OF_PTRACERS)
623    o missing PTRACERS headers in some routines
624    o default tamc.h in pkg/autodiff supposed to crash
625      to ensure proper customization
626    
627    checkpoint52a_post
628    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
629      - moved surfaceTendencyTice from pkg/seaice to main code
630      - subroutine FREEZE_SURFACE now limits only surface temperature
631        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
632        => new output.txt for global_ocean.cs32x15 & global_with_exf
633      - keep the old version of FREEZE for backward compatibility;
634        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
635      - corresponding modifs for TAF directives
636    o added surface flux output variables to TIMEAVE_STATVARS
637    o time-averaged output for pkg/ptracers
638    o fix problem with ECCO-related divided adjoint
639      snapshot file was missing some ad-variables,
640      but no warning issued by TAF
641    
642    checkpoint52a_pre
643    o some bug fixes for #undef REAL4_IS_SLOW
644    
645    checkpoint52 = ecco_c52_e35
646    o after testing adjoints of checkpoint51u_post
647    
648    checkpoint51u_post
649    o this is the post-merge tag of the ecco-branch
650      (needs another clean checkout and re-testing)
651    o various natl_box_adjoint configs and results
652      but no input fields
653    o obcs adjoint not yet merged!
654    o adding ECCO global 1x1 and 2x2 degree configs
655    o updated/extended some store directives for seaice
656    o pkg/ecco now containes ecco-specific part of cost function
657    o top level routines the_main_loop, forward_step
658      supersede those in model/src/
659      previous input data.cost now in data.ecco
660      (new namelist ecco_cost_nml)
661    o in ctrl/ cleaned some cross-dependencies and updated CPP options
662    
663    checkpoint51t_post
664    o this is the pre-merge tag of the ecco-branch
665    
666    checkpoint51s_post
667    o cleanup: removed various obsolete #define-s
668    o pkg/grdchk
669      - renamed 'ph-grd 3' to 'grad-res'
670      - merged from ecco-branch
671        (remaining bug fixes for obcs gradient checks)
672      - additional high-precision output for testreport
673        (grep for 'precision_grdchk_result')
674    
675    checkpoint51r_post
676    o cleaned up or removed CPP_OPTIONS.h files
677    o updated results for some of the tests to reflect the new
678      optfiles (-ieee: -O0 instead of -O3)
679    
680    checkpoint51q_post
681    o cd_code:
682      - moved cd_scheme.F -> cd_code_scheme.F
683      - separate read_checkpoint from cd_code_ini_vars.F
684      - separated cd_code part from write_checkpoint
685      - updated AD_SOURCE, generated .flow
686      - added CD_CODE_VARS.h to the_main_loop
687      - Moving cd_code specific store dir.s to pkg/cd_code
688    o ctrl package totally restructured
689      - pack/unpack now optional and decoupled from
690        xx_/adxx_ I/O
691      - ctrl_pack/unpack cleaned
692        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
693      - confined inclusion of AD_CONFIG.h to where necessary.
694    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
695    
696    checkpoint51p_post
697    o create initial cd_code package
698      - WARNING: the initialization of fields within packages
699        is broken because INI_FIELDS (where READ_CHECKPOINT is
700        called) is called *before* PACKAGES_INIT_VARIABLES.
701        This seems to be backwards since
702        1) its important to initially zero the entire field including
703           the "halo" region
704        2) zeroing needs to be done *before* reading pickup info
705           and the pickup call might or might not happen in any
706           particular run
707      - this needs an overhaul for R2
708    o cleanup verification/*/code/GMREDI_OPTIONS.h
709    o cleanup testreport
710    
711    checkpoint51o_post
712    o bringing AD-related verif's up to date with genmake2
713      - carbon/
714      - global_ocean.90x40x15/

716      - (front_relax/ )
717    o (more) consistent directory structure for AD-related verif.'s
718    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
719    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
720    o bug fix in find_alpha.F for MDJWF:
721      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
722        change rho -> rho-rhoConst
723      - replace call find_rho to find_rhonum
724    o initialisation of rFlx extended to full array (required by TAF)
725      and shifted to thermodynamics
726    o removed PTRACERS.h in ptracers routine
727    o added surfacetendencyPtr to S/R parameter list pracers_forcing
728    o Correcting initialisations for fVerU, fVerV.

735    o added the [#include "AD_CONFIG.h"] statement to all files that need
736       it for adjoint/tl #defines
737     o re-worked the build logic in genmake2 to support AD_CONFIG.h
738     o removed tools/genmake since it no longer works
739    
740    checkpoint51n_post
741    o modifications to make FREEZE flux visible to pkg/kpp
742      - moved surfaceTendencyTice from pkg/seaice to main code
743      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
744      - subroutine FREEZE now limits only surface temperature
745        (this means new output.txt for global_ocean.90x40x15,
746         global_ocean.cs32x15, and global_with_exf)
747    o added surface flux output variables to TIMEAVE_STATVARS
748    
749    checkpoint51n_pre
750    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
751    o added [#include "AD_CONFIG.h"] to all files that use the following
752      defines:
753      - ALLOW_ADJOINT_RUN
754      - ALLOW_TANGENTLINEAR_RUN
755      - ALLOW_ECCO_OPTIMIZATION
756    
757    checkpoint51m_post
758    o incorporating changes to get TAMC/TAF working in genmake2
759      - added new TAMC/TAF targets to the Makefile
760      - various cleanups related to package handling
761      - these changes should have no impact on the forward model
762    
763    checkpoint51l_post
764    o changes to pkg/cal and pkg/exf that allow and speed-up long integrations
765     - faster algorithm for cal_addtime.F

768       model integration time
769    
770    checkpoint51l_pre
771    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
772    o enable to apply restoring on S & T only in a latitude band.
773    o update output (external_forcing_surf modif. change truncation errors)
774       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
775    
776    checkpoint51k_post
777    o change default to: useNHMTerms=.FALSE.
778     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
779       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5
780     - new output.txt for idealized oceanic exp (NHMTerms are now turned off):
781        exp1, ideal_2D_oce

836    o Added on-the-fly spatial interpolation capability
837        "USE_EXF_INTERPOLATION" to pkg/exf.
838      - This is a temporary Cartesian-grid hack until
839        the super-duper ESMF coupler becomes available.
840      - See verification/global_with_exf/README for usage example.
841      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
842        flags and modified pkg/seaice accordingly.

866      (merged from ecco-branch)
867      - new active_file_loc... and mdsio_..._loc routines
868      - affected packages: autodiff, ctrl, grdchk, mdsio
869    
870    checkpoint51c_post
871    o introducing integer flag debugLevel
872      - debLevZero: suppress all output
873      - debLevA: standard
874      - debLevB: equivalent to current debugMode=.TRUE.
875    o introducing pathname variable mdsioLocalDir for mdsio
876      that can be specified at runtime
877      (relevant for cluster I/O to local disk)
878    `
879    >>>checkpoint51b_post
880    adjoint of ptracers
881    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
882    o extended state in checkpoint_lev?, etc.

885    o new ptracers.flow
886    o made ptracers_forcing same as external_forcing_s
887    o added verification for adjoint with ptracers
888      - adm. grdchk fail so far
889      - tlm. grdchk OK
890      - checked tapelev/comlev recomputations: OK
891    <<<checkpoint51b_pre
892

895      - new pkgs: dic, gchem
896      - new subroutine in ptracers
897    o modify code for biogeo packages
898      - in model/src and pkg/ptracers
899    
900    checkpoint51
901    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
902      - autodiff, ctrl, exf, grdchk, seaice
903      kept separate packages
904      - cost, ecco, obcs
905    o updating verification/internal_wave, verification/lab_sea
906      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
907    
908    checkpoint50i_post
909    o Preparing next differentiable checkpoint and sync
910      of MAIN vs. ecco-branch
911      - 1st step: this one is differentiable
912      - 2nd step: next(! not this) checkpoint will have updated packages
913                  from ecco-branch)
914    
915    checkpoint50h_post
916    o new package "land": provide surface BC for AIM.
917    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
918    o AIM: use true log-P extrapolation for near surface temp (= as in
919        F.Molteni paper) ; update aim.5l_cs output.
920    o New variable in PARM03 for more flexible pickups
921    o somewhat cleaned package initialisation sequence for
922      ctrl/ cost/ ecco/ in packages_... routines
923    
924    checkpoint50g_post
925    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
926      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
927      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
928        made the default because of faster convergence than ADI
929    
930    checkpoint50f_post
931    o exf totally restructured
932      - replaced all exf_set_ routines by one generic exf_set_gen.F
933        and made sure it's still differentiable
934      - split exf_getffields.F into new exf_bulkformulae.F
935      - exf_inscal_/exf_outscal_ suffixes consistent with field names

946     o removed lots of single quotes from comments
947    
948    checkpoint50e_post
949    o make KPP work with PTRACERS
950     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
951       nearly a copy of kpp_transport_s
952     - there is no analogue to SurfaceTendencyS, so I have to use
953       gPtr(of the surface layer) instead
954    o add a new platform SunFire+mpi (SunFire 15000) to genmake
955    checkpoint50e_pre
956    
957    checkpoint50d_post
958    o change kpp output from multiple-record state files to single-record state
959      files analogous to write_state.F
960    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
961      analogous to the cg2d-related output.
962    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
963      so that writing to internal file fn (with length 512) fails.
964    checkpoint50d_pre
965    
966    checkpoint50c_post
967    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
968    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
969    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
970    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
971    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
972    
973    checkpoint50c_pre
974    Merging from release1_p13:
975    o bug fix for pkg/seaice dynamic solver
976    o Added SEAICE_initialHEFF to pkg/seaice
977    
978    checkpoint50b_post
979    o store u*,v* in gU,V instead of in guNm1,gvNm1
980    o in order to put the momForcing out of the Adams-Bashforth:
981      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
982      to timestep.F
983    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
984    o re-generate output for highly sensitive test-exp:
985       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
986    
987    checkpoint50b_pre
988    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
989    o corrected CPP option mismatch in exf_Bulk... functions for case
990      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
991    
992    checkpoint50a_post
993    o Bug fix for merging between c50 and KPP.
994      ikey was passed from thermodynamics to kpp_calc via
995      common block rather than being recomputed in kpp_calc,
996      in contradiction with new key itdkey.
997      New key ikppkey created, and tamc.h headers updated.
998    
999    checkpoint50
1000    - 2nd step of merge with ecco-branch:
1001      merge changes in ecco-branch back into main trunk
1002    - bug fix in find_alpha
1003    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1004    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1005    - merged some sliced AD support routines
1006    
1007    checkpoint49
1008    merged from ecco-branch:
1009    o exf:
1010      - Enable initialisation of forcing fields to constant
1011        (runtime) values.
1012      - in exf_getffields.F
1013        Reduce i-/j-loop to interior domain, discarding overlaps.
1014        That also fixes wrong TAF-key computations for key_1, key_2
1015        with bulf formulae.
1016      - exf_init.F modify #ifdef for exf_init_evap
1017      - exf_getffieldrec.F, ctrl_getrec.F
1018        The following INT-usages are not safe:
1019          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1020          fldcount = int(fldsecs/fldperiod) + 1
1021        and were modified.
1022    o autodiff: checkpoint_lev...
1023      - updated storing for bulk formulae (some arrays were missing)
1024      - added state for seaice package
1025      - synchronized with main branch
1026    o DIVA:
1027      Modif.s in
1028      - the_main_loop.F
1029      - the_model_main.F
1030      and added cost_final_restore.F cost_final_store.F
1031      o With these changes, it is possible to fully separate
1032        the first forward run to compute the cost function (mdthe_main_loop)
1033        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1034        into separate model executions.
1035        This enables better tuning of DIVA to given queue sizes.
1036      o Loss of cost function value in consecutive DIVA runs is
1037        fixed by storing to 'costfinal' file.
1038      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1039        beginning/end of adjoint integration is accounted for.
1040      The current changes apply to TAF-1.4.26.
1041      TAF has one remaining bug, requiring one manual change
1042      (see MITgcm manual).
1043    o cal: synchronized between MAIN and ecco-branch
1044    
1045    checkpoint48i_post
1046    o Changes to restore differentiability of code w.r.t. previous tag
1047      (mostly adding new routines to make list and replacing
1048      pressure by totPhiHyd).
1049    o Updated and merged grdchk package
1050      - has both ADM and TLM checks
1051      - works for single- and multi-proc.
1052      - output cleaned
1053      - worked successfully for parallel DIVA
1054    o genmake:
1055      - Adding -platform=SP4
1056      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1057    o Modif. for DIVA:
1058      ctrl_unpack should not be called in intermediate DIVA interval.
1059      (similar thing would apply for active files such as
1060      tbar, sbar, psbar, which should not be reinitialised;
1061      only relevant for ecco-branch)
1062    
1063    checkpoint48h_post
1064    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1065    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1066    o Added SEAICE_initialHEFF to pkg/seaice
1067    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1068    
1069    checkpoint48g_post
1070    --- EOS:
1071    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1072      store total Potential in totPhyHyd for diagnostics & EOS.
1073    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1074    --- Pressure/geopotential gradient:
1075    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1076    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1077      ( changes results of global_ocean_pressure )
1078    o NLFS + z-coord.: add eta*Rho' contribution.
1079    o accurate phiHyd when using interface-W at the middle between 2 centers
1080     ( changes results of ideal_2D_oce )
1081    o includes r* 2nd term in potential gradient.
1082    
1083    checkpoint48f_post
1084    Merging from release1_p12:
1085    o Modifications for using pkg/exf with pkg/seaice
1086      - improved description of the various forcing configurations

1090    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1091      (SBO) core products, including oceanic mass, center-of-mass,
1092      angular, and bottom pressure (see pkg/sbo/README.sbo).
1093    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1094      to avoid negative values in shallow regions.
1095      - updated verification/natl_box/results/output.txt
1096      - updated verification/lab_sea/results/output.txt
1097    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1098    o Added useSingleCpuIO option (see PARAMS.h).
1099    o Updated useSingleCpuIO option in mdsio_writefield.F to
1100      work with multi-field files, e.g., for single-file pickup.
1101    o pkg/seaice:
1102      - bug fix in growth.F: QNET for no shortwave case
1103      - added HeffFile for specifying initial sea-ice thickness
1104      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1105    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1106      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1107    o pkg/seaice:
1108      - adjoint-friendly modifications
1109      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1110    
1111    checkpoint48e_post
1112    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1113    o dynamics: change definition of computational domain & adapt mom_fluxform
1114      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1115    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1116        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1117        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1118        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1119        inverted_barometer solid-body.cs-32x32x1
1120      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1121    
1122    checkpoint48d_post
1123    o in preparation for r*:
1124     a) use pre-computed gradient of hydrostatic potential:
1125        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1126     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1127        => affects results of glob_oce_pressure (different truncation error)  
1128      update output.txt of ideal_2D_oce & global_ocean_pressure
1129    
1130    checkpoint48d_pre
1131    o in preparation for r*:
1132      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1133      pass the 2 comp. of the grad. as arguments to momentum S/R.
1134      but for the moment, only used if it does not change the results.
1135    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1136    
1137    checkpoint48c_post
1138    Modifications in treatment of initial flux forcing controls
1139    to avoid extra storing of flux fields.
1140    
1141    checkpoint48c_pre
1142    o Added tidal_basin_2d experiment (currently 1D!)
1143    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1144    
1145    checkpoint48b_post
1146    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1147     (modification to pressure gradient not yet implemented)
1148    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1149      (for U & V) that are used for vertical advection of momentum.
1150    
1151    checkpoint48a_post
1152    o In preparation for r*, use temp. array to compute vertical transport
1153       in flux-form momentum pkg. => change results of few test-exp.
1154      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1155                        lab_sea, natl_box & plume_on_slope
1156    
1157    checkpoint48
1158    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1159    
1160    checkpoint47j_post
1161    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1162    o moved adexch from forward_step to addummy_in_stepping
1163    o added exch in ctrl_map_...
1164    o aveFreq.=0. at end of cost_final to avoid overwrite in
1165      reverse checkpointing loop
1166    o Yet more changes in gmredi:
1167      * adgmredi_calc_tensor
1168        avoiding all recomputation of gmredi_slope_limit
1169      * adgmredi_x/y/rtransport
1170        added flag for excessive storing to avoid recomp. of
1171        u/v/rtans, dTdx/y/z
1172        -> this is not really necessary and very memory-consuming
1173      * adgmredi_slope_psi:
1174        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1175      * gmredi_slope_limit
1176        re-activated full calculation of taperfct for case 'ac02'
1177    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1178    
1179    checkpoint47i_post
1180    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1181    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1182      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1183    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1184    o gmredi: fix few bugs.
1185    
1186    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1187    This will be a good checkpoint to plug into the ecco-branch.
1188    o few modif.'s to get latest version adjointed
1189      (mainly kick out code in ini_linear_phisurf)
1190    o modif's to run adjoint with exactConserv
1191    o case GM_BOLUS_ADVEC should be cleaned
1192      S/R gmredi_slope_psi should be cleaned
1193    o verification/carbon now has exactConserv=.TRUE.
1194    
1195    checkpoint47g_post
1196    o time-average AIM output: becomes independent from statvars time-average
1197      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1198    o After TAF bug fix:
1199      Tested adjoint of gmredi package.
1200      Tests were done with checkpoint47 rather than with latest
1201      checkpoint47f_post since the latter is broken for the adjoint
1202      verification/carbon/ contains both ADM and TLM gradient checks.
1203    Here they are, before they get changed/lost/stolen.
1204    Mostly modif.'s to fix numerical sensitivities.
1205    Gradient checks OK for
1206    - GM_taper_scheme:
1207      * clipping
1208      * ac02
1209      * linear
1210      * glw91
1211      * dm95
1212      * ldd97
1213    - GMREDI_OPTIONS:
1214      * GM_VISBECK_VARIABLE_K
1215      * GM_NON_UNITY_DIAGONAL
1216      * GM_EXTRA_DIAGONAL
1217      * GM_BOLUS_ADVEC
1218    in conjunction with data.gmredi parameters to be checked in
1219    in a few minutes under verification/carbon/code/
1220    
1221    checkpoint47f_post
1222    Merging from release1_p10:
1223    o modifications for using pkg/exf with pkg/seaice
1224      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1225        and SEAICE_EXTERNAL_FLUXES
1226      - pkg/exf CPP options EXF_READ_EVAP and
1227        EXF_NO_BULK_COMPUTATIONS
1228      - usage examples are Experiments 8 and 9 in
1229        verification/lab_sea/README
1230      - verification/lab_sea default experiment now uses
1231        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1232    
1233    checkpoint47e_post
1234    o created a tag prior to creating a branch
1235    
1236    checkpoint47d_post
1237    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1238      at the bottom boundary had an erroneous half slip boundary condition
1239    o added bottom drag and no slip boundary condition capabilities to
1240      oceanic pressure coordinates code
1241    o added new verification experiment global_ocean_pressure, this experiment is
1242      also described in the tutorial section of the manual
1243    checkpoint47d_pre
1244    
1245    checkpoint47c_post
1246    o Added a verification experiment for a global cubed-sphere ocean run
1247      -  verification/global_ocean.cubed32x32x30
1248      -  uses pkg/therm_seaice and pkg/bulk_forcing
1249    
1250    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1251    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1252      when using P-coordinate; only implemented for atmospheric config.
1253    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1254      NOTES: requires option NONLIN_FRSURF to be "#define".
1255    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1256    
1257    checkpoint47b_post
1258    Merging from release1_p9:
1259    o pkg/seaice
1260      - removed GOTO's and added taf directives
1261      - double precision constants to reduce the g77 (Linux)
1262        to F77 (SGI) differences reported in release1_p8
1263    o tools/genmake
1264      - added SGI options
1265    o verification/testscript
1266      - updated to that of checkpoint47a_post
1267    o verification/global_ocean.90x40x15/input/eedata
1268      - modified for SGI f77 compatibility
1269    o verification/lab_sea
1270      - added description of sea-ice model
1271      - added missing matlab routines
1272      - added test of thermodynamics parallelization
1273    
1274    checkpoint47a_post
1275    o new pkg: aim_v23
1276     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1277       for now, keep the same surface forcing as before.
1278     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1279     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1280     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1281    o add diagnostic of surface correction term in monitor output
1282    
1283    o bulk_force and therm_seaice
1284    - Two packages:  bulk_force (Bulk forcing)
1285      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1286    - Earlier integration from Stephaine Dutkiewicz
1287      and Patrick Heimbach.
1288    - Two ifdef statements for compile time,
1289       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1290    
1291    checkpoint47
1292    differentiable version of checkpoint46n_post
1293    o bug fix in quasihydrostaticterms
1294    o * "clean" adjoint code (in terms of extensive recomputations)
1295        can now be obtained for all GMREDI options (i.e. for
1296        - GM_VISBECK_VARIABLE_K
1297        - GM_NON_UNITY_DIAGONAL
1298        - GM_EXTRA_DIAGONAL
1299        - GM_BOLUS_ADVEC )
1300      * However, wrong gradient check problem remains unsolved.
1301      * New CPP options have been introduced for different
1302        tapering schemes
1303    o external_fields_load now part of differentiation list
1304    o pressure needs multiple storing;
1305      would be nice to have store_pressure at beginning or
1306      end of forward_step, e.g. by having phiHyd global (5-dim.)
1307      (NB: pressure is needed for certain cases in find_rho,
1308      which is also invoked through convective_adjustment).
1309    o recomputations in find_rho for cases
1310     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1311    o #define ATMOSPHERIC_LOADING should be differentiable
1312    o ini_forcing shifted to begining of initialise_varia
1313    o Incorporating QNVS line search routines into MITgcm
1314      (this is separate code, and therefore not under pkg)
1315      lsopt/, optim/
1316    o Updated verification/carbon/
1317      - #define GM_VISBECK_VARIABLE_K
1318      - GM_taper_scheme    = 'ldd97'    
1319    
1320    checkpoint46n_post
1321    Merging from release1_p8:
1322    o verification/natl_box:
1323      updating new external_fields_load routine
1324    o New package: pkg/seaice
1325      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1326      The sea-ice code is based on Hibler (1979-1980).
1327      Two sea-ice dynamic solvers, ADI and LSR, are included.
1328      In addition to computing prognostic sea-ice variables and diagnosing
1329      the forcing/external data fields that drive the ocean model,
1330      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
1331      The implied surface heat flux is then stored in variable
1332      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
1333      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
1334      non-local transport term.  Because this call precedes model
1335      thermodynamics, temperature under sea-ice may not be "exactly" at
1336      the freezing point by the time theta is dumped or time-averaged.
1337      N.B.: fairly large differences in accuracy occur across
1338            different platforms/compilers; comparison between
1339            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
1340            generated output gives:
1341       T           S           U           V
1342      C D M    c        m  s        m  s        m  s        m  s
1343      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
1344      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d

1346    
1347      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
1348    o GAD:
1349      - generated new common blocks to account for call of
1350        same gad routines with differing traceridentities
1351        (needed to modify tracerIdentity indices in GAD.h)
1352      - generated separate common blocks for case useCubedSphereExchange
1353        (Department of Futurology)
1354      - parameter lists to gmredi_?transport: added tracerIdentity
1355      - added new key indices to tamc.h
1356    o external_fields_load:
1357      - added this routine to TAF list
1358      - needed to make some common blocks global and additional storing
1359        along the same lines as exf package (checkpoint_lev?_directives.h)
1360    o exf:
1361      updated external forcing package
1362      - bug fixes carried over from ecco-branch
1363        (missing OBCS_OPTIONS.h in two routines)
1364      - enable easy to use "no forcing".
1365      - added exf I/O for atmospheric loading
1366      - added exf I/O for runoff data
1367      - transfered scaling between exf <-> MITgcm to exf namelist
1368    o Adding new verification experiment global_with_exf.
1369      This verification experiment is almost identical to the
1370      global_ocean.90x40x15 experiment, except that it uses
1371      the exf (and cal) package instead of the
1372      external_fields_load routine (cf README file).
1373    
1374    checkpoint46m_post
1375    o modified testscript to return -- when there are no lines of "%MON" output
1376    o added new flag "quasiHydrostatic" for QH mode
1377      and new routine quasihydrostaticterms()
1378    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1379      New routine: mom_u_coriolis_nh()
1380    o fixed sign of non-hydrostatic metric terms in u and v equations.
1381      Depend on correct sign of gravitySign.
1382    o added work.pc* to .cvsignore in aim directories using ifc
1383    o introduced flag for controllin non-hydrostatic metric terms
1384    o removed gravitySign from PARM04
1385    o switched to g77/ifc from pgf77 in aim experiments
1386    
1387    checkpoint46l_post
1388    o made convective adjustment work with pressure coordinates:
1389     - changed the direction of k-loop in convective_adjustment.F for the
1390       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1391     - adjusted the reference pressure k-index in convective_adjustment.F
1392     - adjusted the convection condition in convect.F (in analogy to
1393       calc_ivdc.F)
1394     - convective_adjustment no longer computes anything on the halos
1395     - removed the warnings about negative salinity from find_rho.F and
1396       find_alpha.F; instead the new routine look_for_neg_salinity, called
1397       at the beginning of find_rho, find_alpha, and find_beta, does a
1398       check of the entire slice, if CPP-option
1399       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1400    checkpoint46l_pre
1401    
1402    checkpoint46k_post
1403    o fixed the verification/global_ocean.90x40x15 experiment:
1404     - new bathymetry (the world according to A., JMC, and M.)
1405     - new initial fields and forcing fields (*.bin files)
1406     - new POLY3.COEFFS (for the next release one should switch to a full
1407       equation of state: JMD95P or MDJWF)
1408     - fixed several errors and redundancies in the data file
1409     - experiment uses looped cells
1410     - added matlab directory with diagnostic scripts for plotting of output
1411    
1412    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1413     - read AIM physics parameters from a file (data.aimphys)
1414     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1415    
1416    checkpoint46j_post
1417    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1418    o move wVel computation at the end of the time step, in S/R integr_continuity
1419    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1420    o update timeave pkg for wVel diagnostic.
1421    checkpoint46j_pre
1422    
1423    checkpoint46i_post
1424    o Clean up AIM package (and keep the results unchanged):
1425      include CPP_OPTION and use IMPLICT NONE in all routines ;
1426      declare all the variables _RL ; use _d 0 for all numerical constants.
1427      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1428    
1429    checkpoint46h_post
1430    o cleaned up the use of rhoNil and rhoConst.
1431      - rhoNil should only appear in the LINEAR equation of state, everywhere
1432        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1433        and the dynamical equations are all divided by rhoConst
1434    o introduced new parameter rhoConstFresh, a reference density of fresh
1435      water, to remove the fresh water flux's dependence on rhoNil. The default
1436      value is 999.8 kg/m^3
1437    o cleanup up external_forcing.F and external_forcing_surf.F
1438      - can now be used by both OCEANIC and OCEANICP
1439    checkpoint46h_pre
1440    
1441     Added code to convert surface volume flux (fresh water) into
1442     a mass flux when using P coordinates in the ocean (OCEANICP).
1443     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1444    
1445    checkpoint46g_post
1446    o Include a new diagnostic variable phiHydLow for the ocean model
1447      - in z-coordinates, it is the bottom pressure anomaly
1448      - in p-coordinates, it is the sea surface elevation
1449      - in both cases, these variable have global drift, reflecting the mass
1450        drift in z-coordinates and the volume drift in p-coordinates
1451      - included time averaging for phiHydLow, be aware of the drift!
1452    o depth-dependent computation of Bo_surf for pressure coordinates
1453      in the ocean (buoyancyRelation='OCEANICP')
1454      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1455        Theta, Salinity, and Pressure in the parameter list. This routine is
1456        presently contained in find_rho.F. This routine does not give the
1457        correct density for 'POLY3', which would be a z-dependent reference
1458        density.
1459    o cleaned up find_rho
1460      - removed obsolete 'eqn' from the parameter list.
1461    o added two new verification experiments: gop and goz
1462      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1463    checkpoint46g_pre
1464    
1465    checkpoint46f_post
1466    o Enable tangent linear (forward mode) gradient checks:
1467      - extended active file handling to g_... files
1468      - added TANGENT_SIMULATION to theSimulationMode
1469      - extended grdchk package accordingly
1470    o added tangent linear setup in verification/carbon/code_ftl
1471    o added adjoint setup in verification/front_relax/code_ad
1472    
1473    checkpoint46e_post
1474    o Added new equation of state -> MDJWF
1475      - EOS of McDougall et al., 2002, JAOT, submitted
1476      - caveat: the equation of state is only valid for a smaller (more
1477        realistic?) range of values than JMD95P/Z and UNESCO
1478      - added masks to the calculation of pressure in store_pressure
1479      - added more check values for density in check_eos (ini_eos.F), some of
1480        the old check values are out of the range of the MDJWF-eos, so don't
1481        expect perfect matches for those
1482    checkpoint46e_pre
1483    
1484    checkpoint46d_post
1485    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1486      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1487      case of pressure coordinates. eosType='JMD95Z' in
1488      combination with buoyancyRelation='OCEANICP' now causes an error.
1489    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1490      in find_alpha/beta.
1491    checkpoint46d_pre
1492    
1493    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1494      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1495    
1496    checkpoint46c_post
1497    o Changes necessary for ocean in p-coordinates
1498     -  Added new buoyancy relation = 'OCEANICP'
1499     -  Added new parameters = gravitySign (this used to be contained inside
1500        the factor dRdZ which I added when we first switched to R coordinates).
1501     X GM/Redi is not compatible (yet)
1502     X bottom drag and no-slip need to be debugged.
1503    checkpoint46c_pre
1504    
1505    checkpoint46b_post
1506    o Added new equation of state -> JMD95Z and JMD95P
1507      - EOS of Jackett and McDougall, 1995, JAOT
1508      - moved all EOS parameters into EOS.h
1509      - new routines ini_eos.F, store_pressure.F
1510    o Added UNESCO EOS, but not recommended because it requires
1511      in-situ temperature (see JMD95)
1512    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1513      unesco.f to be used with POLY3
1514    checkpoint46b_pre
1515    
1516    checkpoint46a_post
1517    o Added (atmospheric) pressure loading
1518      - new field in FFIELDS.h, etc...
1519      - new cpp flag ATMOSPHERIC_LOADING
1520    o Changed hFacC to _hFacC in calc_phi_hyd.F
1521    o Added SHORTWAVE_HEATING to some files for consistency
1522    checkpoint46a_pre
1523    
1524    checkpoint46
1525    further merges from release1_p5
1526    o new ctrl package
1527      - adopted from ECCO environment to enable optimization
1528      - added Eliassen Palm fluxes to controls
1529    o added Eliassen Palm flux controls to gradient check package
1530    o cost package
1531      - Compatible with new ctrl package
1532      - added Eliassen Palm cost hooks
1533      - modif's of existing cost functions
1534    o Adjoint-related bug fixes in kpp:
1535      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1536      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1537    o autodiff package
1538      - flow directives:
1539        + new for S/R do_the_model_io
1540        + enhanced for S/R checkpoint
1541        + new gmredi.flow
1542      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1543        disable adcommon.h/g_common.h by default.
1544      - fixed problem for adjoint of global_max
1545    o modified verification/carbon/
1546    o New setup for adjoint of global_ocean
1547    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1548    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1549    o incorporated hooks for sponge layer code (external_forcing.F)
1550    
1551    checkpoint45d_post
1552    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1553    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1554      (affects plume_on_slope "cg2d" output)
1555    o add new parameter deltaTfreesurf for free-surface time stepping
1556    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1557    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1558    o change phiMin in exp1 (to agree with documentation)
1559    o add new flags:
1560     - T,S forcing inside/outside Adams-Bashforth
1561     - turn off temp,salt advection and/or forcing
1562     - for each tracer, define internal flag for multiDimAdvection & A-B
1563    o monitor: change definition of KE to check conservation of Energy
1564    
1565    checkpoint45c_post
1566    o Removed f90 comments ("!")
1567    o Modified initialisations to enable exf package for MITgcm
1568      (without invoking ECCO_PACKAGE).
1569    o modifications to gradient check package (Martin Losch)
1570      - enable centered differences
1571      - modified format of standard output
1572    
1573    checkpoint45b_post
1574    o cleaned exchange calls in cg2d
1575    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1576    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1577      to configure barotropic setup (Martin Losch)
1578    o moved some initialisations within bi,bj loop in dynamics
1579      (TAF flow dependency)
1580    o in initialise_varia, moved call packages_init_variables
1581      before convective_adjustment_init
1582      (corresponding adjustment of TAF tape initialisation).
1583    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1584    
1585    checkpoint45a_post
1586    o compute Rho over the whole domain (extend iMin,jMin indices)
1587    o specific exchange for X-slice domain (case Ny=1)
1588    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1589    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1590    
1591    checkpoint44h_post = checkpoint45
1592    o Fix to restore differentiability:
1593      place at which packages_init_variables is called in
1594      initialise_varia is crucial for reverse control flow.
1595    o modifications in GMRedi to enable stable adjoint
1596      (corresponding modif's in thermodynamics, dynamics)
1597    o added missing hook for sponge layer code in external_forcing
1598    o modified test cost functions
1599    o storing in gad_advection (plus removal of write(0,*)!
1600    o missing headers TR1.h added in convective_adjustment routines

1604    
1605    checkpoint44h_pre
1606    o vertical grid option: allow to put the Interface at the middle between
1607      2 cell-centers ; replace delZ in pkg/kpp by drF.
1608    o GM Advective form: Tracers are advected using the residual transport (=
1609      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1610    
1611    checkpoint44g_post
1612    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1613      results) ; ifdef missing in thermodynamics.F
1614    
1615    checkpoint44f_pre,checkpoint44f_post
1616    o added PTRACERS package
1617      This allows an arbitrary number of passive tracers to be integrated
1618      forward simultaneously with the dynamicaly model.
1619      + Implemented so far:
1620        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1621        - I/O and checkpointing
1622        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1623      + Not implemented so far:
1624        - KPP
1625        - OBCS
1626      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1627        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1628        line in data.pkg.
1629      + This package is disabled by default since it increases storage.
1630    
1631    
1632    o testscript: added -cleanup option
1633    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1634                 b) enable to filter 2D fields.
1635    
1636    checkpoint44e_pre,post
1637    o re-wrote convective adjustment to use pre-calculated weights
1638      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1639      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1640      Original calls to convect() still in place.
1641    
1642    chkpt44d_pre,post
1643    o added missing EXCLUDE_MONITOR flags
1644    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi

1648      plus resetting for case SunOS
1649    o added timer_stats.c routine for IBM SP3
1650    o removed variables in dynamics
1651    !!! I forgot to create tag chkpt44d_pre !!!
1652    !!! But chkpt44d_pre = chkpt44c_post    !!!
1653    
1654    o real fresh water flux implemented with non-linear free-surface.
1655    
1656    chkpt44c_pre,post
1657    o few fix (mask in shap_s2, EmPmR in external_field_load,
1658      USE_NATURAL_BCS in solve_for_P);
1659    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1660    
1661    checkpoint44b_pre/_post
1662    o merge of relevant stuff from the ecco-branch:
1663      - genmake: removed $S64 overwrite for case SunOS
1664      - pkg/exf: update and corrections for field swapping and obcs
1665      - pkg/ecco: parameter lists for the_model_main, the_main_loop

1688    o some final mods for gradient check, adjoint,...
1689    
1690    checkpoint42
1691      Fixed AD-related problems:
1692    o Store directives up-to-date with re-arranged Adams-Bashforth
1693      (mainly thermodynamics.F)
1694    o New store directives for multi-dim. advection schemes
1695      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1696      * new common block and key passkey
1697      (mainly gad_advection.F)
1698    o Modified store directives for split of dynamics/thermodynamics
1699      for the case ALLOW_KPP
1700    o Cleaned argument list for timestep_tracer.F
1701    
1702    checkpoint41

1722    o added/updated many matlab scripts
1723    o added multi-dimensional advection method for tracers
1724      
1725    checkpoint40pre8
1726    o new package rw/
1727      Added method for dumping intermediate local arrays:
1728      mdsio_writetile - same as mdsio_writefield except works from inside
1729                        bi,bj loop
1730      mdsio_writelocal - same as mdsio_writetile except works for local
1731                         arrays
1732      write_local_r? - higher-level wrapper for mdsio_writelocal
1733      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1734      Example given at end of mom_vecinv.F that dumps some local arrays.
1735    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1736      control flux-form versus vector invariant code.
1737      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1738      or genmake -DISABLE ...
1739    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1740      (additional storing is now needed for case vecinv;
1741      currently nothing implemented to switch this storing off
1742      in case fluxform is used since no CPP flag available).
1743    
1744    checkpoint40pre7
1745    o bug fix in dynamics.F
1746      calc_viscosity called before k=1,Nr loop.

1757    o bug fix in gmredi_slope_limit for ldd97
1758    
1759    checkpoint40pre5
1760    o proper initialization of Adams-Bashforth time stepping
1761      + uses forward step for very first step of model (iter=0)
1762    o re-generated *all* output since almost all output is modified by this
1763      change (sorry but we've been putting this one off for about 2 years)
1764      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1765        *not* regenerated since they are already out of date and I don't
1766        want to create the impression that they are suddenly working.
1767    o removed KAP stuff for DEC's
1768    o modified/added many .cvsignore files in */code and */input
1769    o added new expt "solid-body.cs-32x32x1"
1770      + this uses an alternative form of ini_curvilinear_grid.F which
1771        is not necessarily any better than the current one...
1772    
1773    checkpoint40pre4
1774    o added re-initialisations of utrans,vtrans,rtrans in
1775      calc_common_factors which are crucial for TAF.
