5      ==============================      ==============================
6    
7    o pkg/kpp: replaced _KPP_RL with _RL
8    o bug fixes for vertical diffusivity computations when both KPP and
9        3D diffusivity arrays are used.
10    o pkg/seaice: fix bug in evp solver, while doing that
11      - change (improve?) discretization of stress computations for both
12        cgrid-lsr and evp solver
13      - add a new routine to compute strain rates
14      - the above changes lab_sea results
15      - add no slip conditions for evp solver (off by default), lsr-version
16        may follow
17      - fix exchange for shear at Z-points (does not change lab_sea)
18      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
19        (to force the user to pick a time step since there is not "safe" way
20        of choosing it)
21      - add principal stress diagnostics
22      - rearrange fields for evp a little to avoid having to call a: too many
23        exchanges and b: exchanges for stress trensor components which we do
24        not have.
25      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
26        of evp, complete rewrite for lsr case (latter is does not yet work
27        in all cases)
28    o pkg/kpp: add code to have mixing in shelf ice caverns
29    
30    checkpoint59
31    o pkg/exf:
32      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
33        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
34      - move exf header files from lower_case.h to UPPER_CASE.h ;
35        add missing cvs Header & Name
36      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
37      - add namelist param. selectStressGridPosition, exf_monFreq
38      - retire many _CLIM routines, and remove data.exf_clim
39        + params moved to data.exf
40        + climsst, climsss now handled by exf_set_gen, i.e.
41          climss?period=0 refers to constant field,
42          climss?period=-12 to monthly forcing
43      - split up namelists in data.exf
44    o pkg/seaice:
45      - remove seaice_exch and seaice_exch_uv
46      - remove superfluous exchange of theta
47      - add myThid to seaice_budget_ocean/ice
48      - add new interface for atmospheric wind forcing (C-grid only)
49        + new routine
50        + two new field (taux, tauy for stress over ice)
51        + removed one global field (DAIRN) for C-grid case only
52    o pkg/thsise
53      - 2nd set of modifs for thsice adjoint in conjunction with exf
54    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
55    
56    checkpoint58y_post
57    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
58      vertical diffusivity, similar to that in MOM4; turned on using
59      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
60      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
61    o Added capability for 3D specification of background vertical diffusion
62      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
63      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
64      "data" file that contains the 3D vertical diffusivity coefficients.
65    o ice dynamics (pkg/seaice) with thsice thermodynamics:
66      - add code within pkg thsice to advect & diffuse sea-ice fields
67      similar to (and will replace) what has been added in  seaice_advdiff.F,
68      but: - conserving Mass, Heat & Salt.
69           - better when using non-linear advection scheme (not yet fully tested)
70           - can also be used in atmospheric set-up (for now, only the diffusion).
71    
72    checkpoint58x_post
73    o IO option for global-file compact format:
74      - add options when generating topology (utils/exch2/matlab-topology-generator)
75      - add I/O capability (pkg/mdsio).
76      - adapt utils/matlab/rdmds.m to read this format.
77      for now long-line format not yet supported by pkg/mdsio (& exch2).
78    o shelfice: add a few diagnostics
79    
80    checkpoint58w_post
81    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
82      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
83      (and replace horiVertRatio in NH code).
84      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
85                         and tutorial_plume_on_slope (sensitive to truncation)
86    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
87      directly to drive seaice model (C-grid only)
88    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
89     - reintroduce computation of wind from stress,
90     - compute tau (in exf_bulkformulae.F) from windstress averaged to
91       mass points to avoid tau = 0
92     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
93    o rdmnc.m: make it work with "global" files created with gluemnc
94    o rdmnc.m : some improvements in dealing with singleton dimension
95      (tested on all testreport mnc output files).
96    o genmake2: disable pkg/profiles if netcdf test fails.
97    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
98    o move call to cal_readparms up to make calendar parameters/variable available
99      to all packages
100    
101    checkpoint58v_post
102    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
103      useDynP_inEos_Zc tested.
104    o pkg/exf: changes to properly interpolate/mask/scale initial fields
105    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
106      and portions thereof.  See read_cs.txt for description and examples.
107    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
108      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
109      following the great-circle arc between those 2 points.
110    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
111      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
112    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
113     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
114     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
115     - still needs work (not working with some options ; efficiency to improve)
116       and serious testing.
117     - use this scheme for temperature & salinity in 2 advection test exp.:
118       advect_xy & advect_xz, respectively.
119    
120    checkpoint58u_post
121    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
122    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
123    o testreport: add option "-skipdir" to skip some test.
124    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
125      momentum calculation.
126    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
127    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
128      remove checkpoint.F and the_correction_step.F (no longer used);
129      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
130    o add option (linFSConserveTr) to correct for tracer source/sink due to
131      Linear Free surface
132    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
133    o pkg/thsice: fix reading mnc-pickups
134    
135    checkpoint58t_post
136    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
137    o pkg/mdsio:
138     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
139       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
140       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
141     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
142     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
143       either MDS_READ_FIELD or MDS_WRITE_FIELD )
144     - new S/R (to replace MDSWRITEMETA), which allows to write more
145       informations (variable names, time ...) to meta files.
146     - modify rdmds.m to give back the meta file content.
147    o pkg/diagnostics: change vertical interpolation to be safer, and more
148       flexible (define p-levels to interpolate to in data.diagnostics);
149      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
150       diagnostic pointer.
151    o pkg/seaice: more cleaning up of seaice_growth, added many comments
152    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
153    o fix multi-category seaice:
154     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
155       SEAICE_MULTICATEGORY
156     - fix short wave heat flux
157    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
158       and allow to use EVP solver. Change forward lab_sea: test both EVP
159       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
160    o Initial check-in of lab_sea adjoint
161      (very similar to natl_box_adjoint/code_seaice)
162      * used C-grid and EVP solver
163      * used KPP, GM/Redi
164      * uses inAdExact=.TRUE.
165      * gradient checks fail for both ADM and TLM
166        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
167        f.d. gradients actually seem more problematic than ADM, TLM gradients;
168        issue is related to forward mismatch between g77 an ifort
169    o pkg/seaice: overhaul of thermodynamics
170     - growth.F and groatb.F are replaced by new routine seaice_growth.F
171     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
172     - move a few global fields out of SEAICE.h into seaice_growth.F and
173       make them 2D (FICE/QNETO/ ...)
174     - remove FO (it is the same as QNETO)
175     - introduce a few local fields to avoid modifying external fields such
176       as atemp, etc.
177    
178    checkpoint58s_post
179    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
180      changed exf_set_gen.F so that
181        genperiod=0 means input file is one time-constant field and
182        genperiod=-12 means input file contains 12 monthly means
183    o CG2D: use pre-computed solver main-diagonal (stored in common block);
184      this affects truncation error ; generate new output file for exp. which
185      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
186        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
187        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
188        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
189        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
190        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
191    o start implementation of deep-atmosphere and anelastic formulation
192    o verification: remove 2nd copy of input files and use script "prepare_run"
193      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
194    o mom_common/vecinv/fluxform: fix a few initialisation isssues
195    o profiles: fix for multithreaded case
196    
197    o diagnostics: rename few diags:
198      s/'PRESSURE'/'RCENTER '/g
199      s/'TICE    '/'oceFreez'/g
200      s/'TAUX    '/'oceTAUX '/g
201      s/'TAUY    '/'oceTAUY '/g
202      s/'SWFLUX  '/'oceQsw  '/g
203      s/DIFx/DFxE/g
204      s/DIFy/DFyE/g
205      and add few ocean-forcing diagnostics:
206      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
207    o modifications to pkg/seaice/growth.F and budget.F, which change results of
208      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
209      as actual snow thickness.  It now refers everywhere to effective snow
210      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
211    
212    checkpoint58r_post
213    o modifications to pkg/seaice/growth.F, which change results of
214      lab_sea experiment: fixes pertain to melting snow over open water, to
215      masking EVAP under sea ice, and to using the correct AREA variable for
216      computations of EVAP, PRECIP, HSNOW, and GHEFF
217    o add ability to read bathy, salt, and theta using MNC (off by def)
218    o add flooding algorithm and advection of HSNOW for pkg/seaice;
219      both are turned off by default and do no change any results
220    o seaice advection with pkg/thsice: a step toward the use of non-linear
221      advection scheme, but #ifdef or commented out for now (requires more EXCH).
222    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
223      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
224      in natl_box (affects results @ truncation level: update output.txt)
225    o multi-threading and IO:
226      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
227      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
228        (needed to work with SingleCpuIO): tested in all verif. exp.
229    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
230      affects the results (but none of the verification test uses this scheme).
231    o Adding some pkg/diagnostics capability to pkg/seaice
232      (will certainly be subject to changes)
233    o ctrl: adding new control variables:
234      lwflux, lwdown, evap, snowprecip, apressure, runoff
235    
236    checkpoint58q_post
237    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
238      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
239      high_res_cube configuration by 4% on Columbia.
240    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
241      add (in global_with_exf/code) a version of EXF_INTERP_READ without
242      dynamical allocation (seems to work in multi-threaded).
243    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
244      single CPU io) so that TAF does not have to see EESUPPORT.h
245    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
246    
247    checkpoint58p_post
248    o obcs: stop if obcs is used with useCDscheme = .true.
249    o shelfice:
250     - fix a sign error so that no slip at shelfice interface works
251     - remove stop for combination non-hydrostatic code and shelfice. That does
252       not mean, that the results are correct, but at least they are numerically
253       stable
254    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
255    o added adjoint exch routined for all exch*3d* routines
256      and updated flow directives
257    
258    checkpoint58o_post
259    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
260      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
261    o change controling S/R for writing pickup file (new S/R do_write_pickup)
262      and clean-up reading/writing of pickup files.
263    o fix local version of read/write pickup (NH part) in rotating_tank/code
264    o simplify EXCH interface:
265     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
266     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
267    o added the regrid package
268    o shelfice:
269     - add a simple boundary layer scheme to reduce noise
270     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
271    
272    checkpoint58n_post
273    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
274       local variable (not in common block).
275    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
276      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
277      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
278        to work with SingleCpuIO.
279    o add "_d 0" to real constant of pkg/cfc subroutines ;
280       update exp. cfc_exemple & tutorial_cfc_offline output files.
281    o multi-threading and IO:
282      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
283        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
284      - barrier before and after reading.
285      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
286      - avoid using MDS_WRITELOCAL for LAND pkg output.
287      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
288        common-block variables ; Allows multi-threading with master-thread IO.
289    o change default MAX_NO_THREADS from 32 to 4 ;
290      and stop cleanly when MAX_NO_THREADS is too small.
291    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
292    
293    checkpoint58m_post
294    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
295       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
296    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
297       keep global_ocean.90x40x15 (for AD testing) with former secondary test
298       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
299    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
300        add MITgcm_tutorials (= code + all the tutorials)
301    o ecco, option to compute cost for total ssh (mean+anom)
302    o consistent with addition of ptracer and ssh in pkg/profiles
303    o profiles: adding ptracer and ssh
304    o testreport: change multi-test output-file name
305      (from output.txt.{name} to output.{name}.txt)
306    o profiles: now ok for mutli-tiles case
307    o seaice: add 4 parameters for different advection schemes for area,
308      (effective) seaice thickness, enthalphy, and snow height. Their default
309      is the standard parameter SEAICEadvScheme
310    o calc_gw:
311     - add cosFacU in zonal viscous flux (harmonic.visc.).
312     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
313       of tutorial_plume_on_slope.
314    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
315    o calc_gw: true flux-form, account for horizontal grid spacing.
316      update rotating_tank results, but not plume_on_slope (affected at
317      truncation level, 11 digits).
318    
319    checkpoint58l_post
320    o calc_gw:
321     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
322     - remove side-drag for now (need to fix it); update plume_on_slope results.
323     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
324    o commit code to make SST/SSS weights spatially variable
325      (based on either variable in-situ or variable initial T/S weights)
326    o pkg/ecco:
327      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
328        now based on horizontally varying weights wthetaLev, wsaltLev
329      * cost_averagesflags now returns year indices in addition to day, month
330      * sflux balance is performed on annual basis
331        (sflxumm, sfluxmm2, bal_sfluxmm)
332      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
333        including separate counting and multipliers
334    o pkg/rbcs
335      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
336    
337    checkpoint58k_post
338    o testreport:
339     - always build in dir. "build" (if not there, mkdir build instead of building
340       & running in input)
341     - run in dir run (if it exists), in build otherwise.
342     - call prepare_run (if input/prepare_run exists)
343     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
344    o pkg/exf modifications to interpolation and rotation routines for more
345       reasonable treatment of North Pole singularity: for tracers North Pole
346       value is set to northernmost zonal-mean value, for zonal velocity it is
347       set to zero, and for meridional velocity it is set to northernmost value.
348    o pkg/exf/exf_check_range.F
349     - add tile index to diagnostics and move stop statement to the very
350       end of the routine.
351    o pkg/diagnostics: (diagnostics_main_init.F)
352      define title of isomorphic variables according to the current config.
353    o pkg/thsice with pkg/seaice dynamics:
354    - fix domain of computation (interior only, required for exf) and do exchanges
355    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
356    o towards a standard way of dealing with multi-threading in MONITOR
357      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
358    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
359       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
360    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
361    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
362    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
363       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
364    o tracer advection:
365     - clean-up and simplify calc_common_factors.F
366     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
367       advection subroutine (but still not used within DST advection S/R)
368    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
369    
370    checkpoint58j_post
371    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
372      from file (collects calls previously in FORWARD_STEP)
373    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
374    o adjoint store dir. adjusted accordingly
375    o genmake2
376      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
377    
378    checkpoint58i_post
379    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
380      on wind stress (SEAICEstressFactor defaults to 1.)
381    o Total number of Timers is finite (<=40): comment out 2 non-essential one
382      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
383    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
384      on CS-grid: no longer loosing mass.
385    o exf & curvilinear-grid: no longer modify longitude xC & xG.
386    o pkg/ggl90: fix sloppy output and fix a bug
387    o pkg/seaice: added SEAICEuseEVPpickup parameter
388      - Set to false in order to start EVP solver with
389        non-EVP pickup files when using SEAICEuseEVP
390      - fix sign error in diffusion in seaice_calc_rhs
391    
392    checkpoint58h_post
393    * Modifications for bottom topography control
394      o replace hFacC by _hFacC at various places
395      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
396      o add non-self-adjoint cg2d_nsa
397      o update autodiff support routines
398      o re-initialise hfac after ctrl_depth_ini
399      o works for 5x5 box, doesnt work for global_ocean.90x40x15
400    * Adding verification for 5x5 box (4-layer) bottom topography control
401    
402    checkpoint58g_post
403    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
404       used for mean seasonal cycle, mean diurnal cycle); add an example
405       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
406    o pkg/ggl90:
407      - add parameter (minimum surface kinetic energy)
408      - fix bug (avoiding division by zero)
409    o couple pkg/thsice to pkg/seaice:
410      - modify advection in seaice to accomodate new scalar fields to be advected
411      - only muliDimAdection scheme work with seaice/thsice
412      - mapping of thsice-variables to seaice-variables, back and forth
413      - does not break the verification experiments, but does not give the
414        desired results either
415    o pkg/seaice
416      - make (default) second order advection a bit less confusing?
417    
418    checkpoint58f_post
419    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
420      to pkg/seaice):
421      - new routines thsice_map_exf and thsice_get_exf provide the interface
422      - add an additional formal parameter to thsice_solve4temp
423    o pkg/exf:
424      - add new fields wspeed, snowprecip (to be able to couple to thsice)
425      - correct Stefan-Boltzmann constant
426      - new parameter for longwave surface emittance
427      - separate some stuff from exf_bulkformulae into new routines  
428        exf_radiation, exf_wind
429      - add new parameters and constants: longwave emissivity for ocean, ice
430        and snow, evaporation parameters over ice
431      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
432        either wind from stress or stress from wind
433    o pkg/thSIce:
434    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
435    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
436       and THSICE_CALC_THICKN
437    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
438    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
439      to make debugging easier.
440    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
441    o pkg/bulk_force:
442      - clean-up comments and parameters ;
443      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
444    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
445      generate new output for test-experiment: aim.5l_cs.thSI
446    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
447      testreport accordingly
448    
449    checkpoint58e_post
450    o SEAICE_CGRID adjoint done
451    o R_STAR adjoint implemented.
452      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
453      * need to sort out init. of h0facc, etc.
454    o Make pkg/profile fully independent of ecco,cost, etc. stuff
455      to be able to use it in pure forward.
456    
457    checkpoint58d_post
458    o upgrade simple test-experiment to tutorial example:
459     step.1: duplicate the experiment and (step.2) will remove the old copy.
460      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
461      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
462      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
463      tutorial_global_oce_biogeo    <- copy of dic_example
464      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
465      tutorial_plume_on_slope       <- copy of plume_on_slope
466      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
467      tutorial_global_oce_optim     <- empty for now (David ?)
468      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
469     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
470    o correct a sign problem in cost_scat.F
471    o obcs and ptracers: fix boundary conditions for advections schemes
472      with larger stencil
473    o thsice adjoint: start
474    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
475      completeness
476    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
477      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
478    o ptracers adjoint:
479      * avoid extensive recomputatations
480      * fix missing re-init. of gptr (missed by TAF)
481    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
482      me to turn off the excessive output to STDOUT that this package produces
483    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
484      and add those terms in Vector-Invariant formulation.
485    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
486      if the control period (xx_hfluxperiod etc) is 0
487    o in profiles pkg, clean routines and fix details
488    o in ecco pkg, reading ssh data:
489      fix problem in case the model does not start at iter0=0
490    o fix mnc-pickup/restart for ptracers
491    o new package prifiles:
492      code to compute profile-based cost by Gael Forget
493      (modifs in ecco, ctrl, autodiff)
494    o Benign bug fix in initialization (spotted by M. Mazloff) of
495      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
496    
497    checkpoint58c_post
498    o adjoint: finish NLFS adjoint and provide reference output in
499      verification/global_ocean.90x40x15/results_ad_nlfs
500    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
501      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
502      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
503      with SEAICE_CGRID defined.
504    o move calendarDumps from "data" to "data.cal" and clean-up the code
505      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
506    o add useEXF & useCAL flags (for now, set in hard-coded way)
507    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
508      (were missing in NH mode, and wrong in quasihydrostatic mode).
509      waiting for Chris updated version of calc_gw to add those CALLs.
510    o fix bug in quasihydrostatic S/R ;
511      add a test for this option: global_ocean.90x40x15.qshyd
512    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
513      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
514    o add on/off flag useOffLine for package OFFLINE
515    o seaice:
516      - modify advection so that it works also on the C-grid
517      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
518        problem in multi-tile runs with C-grid
519      - add flags for clipping ice velocities and/or masking solver forcing
520      - fix drag (ocean on ice) formulation and a bug that caused noise in the
521        C-grid solver
522      - added a few comments to seaice_diffusion.F
523      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
524        are now exclusive)
525      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
526        required re-ordering the code a little:
527       + make DAIRN global variable (defined in SEAICE)
528       + move computation of the viscosities eta and zeta into a new separate
529         routine (because I need to recompute them in seaice_ocean_stress.F)
530    
531    checkpoint58b_post
532    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
533      update output.txt of exp. aim.5l_cs.thSI
534    o various mnc cleanups and improvements:
535      + shrink lookup tables by factor of ~4
536      + better error reporting when running out of lookup space
537      + able to handle longer path/file names (up to 500 chars)
538    o adjoint:
539      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
540      - TBD: "hidden" mom_vecinv recomp. in dynamics
541    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
542     (allow to differentiate between forcing components using new integer flags:
543      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
544     and add new flag to put Dissipation tendency out of Adams-Bashforth.
545    o ecco
546      - enable trend removal from SSH anomaly obs.
547    o adjoint
548      - a fix for PmEpR when #undef EXACT_CONSERV
549      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
550      - try to fix "hidden" recomp. in forward_step for NLFS
551        (NLFS seems broken sometimes after I checked it in)
552    o seaice:
553     - add c-grid version of the dynamic solver:
554       + three new routines that are the c-grid substitute lsr, dynsolver
555         and ostres
556       + put a few fields that were local to dynsolver into global common
557         blocks, so that I can move the computation of stresses etc into
558         seaice_lsr (saves coding but may break the adjoint).
559     - replace more hardwired parameters by runtime parameters
560     - add ice masks that mask the rhs of the implicit solvers where there
561       is no ice (commented out in seaice_dynsolver, because i am not sure
562       if this works properly), eventually this should replace the clipping
563       of ice velocities in seaice_dynsolver to +/-40cm/s.
564    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
565      include it only where its needed
566    o move balancing of fluxes before the call of external_forcing_surf
567    o seaice:
568      - correct units of turning angles (now they are really in degrees)
569      - move computation of GWATX/Y out of main routine into dynsolver
570      - initialize GWATX/Y in seaice_init
571    o Apply mask on Fresh-Water flux (needed for SSH forcing).
572      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
573    o seaice: add runtime flags for turning angles (default to zero)
574    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
575      and trend from exf forcing and ctrl control adjustments
576    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
577      (since checkpoint57x_post)
578    o change the default rotation period to 86164.s = the Earth rotation
579    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
580      and based on a reference stratification. Tested within hs94.cs-32x32x5.
581    o seaice advection: add code for choosing between the default (2nd order
582      central differences) and multiDim advection schemes provided by
583      pkg/generic_advdiff
584    o seaice:
585      - removed all references to SEAICE_GRID.h fields from
586        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
587        (cubed-sphere configuration will change a little)
588      - grid computations in seaice_init are obsolete now.
589      - cleaned up code a little so that is easier to read (hopefully).
590      - added new (better?) discretizations of default advection and diffusion
591        (turn on with SEAICEuseFluxForm)
592      - replace 1 in 3d global fields by kSurface in growth.F
593      
594    checkpoint58a_post
595    o seaice:
596      - bug fix in advect.F
597    o shelfice:
598      - separate shelfice load anomaly from pload (breaks with time
599        dependent forcing), => introduce constant field shelficeLoadAnomaly.
600        Its default is 0., but it may be computed more cleverly from (unknown)
601        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
602        done offline. A good approximation of the pressure load anomaly is
603        necessary to avoid large initial adjustment processes underneath
604        deep-reaching shelfice.
605      - small fix in ISOMIP shelfice_thermodynamics
606      - add more sophisticated thermodynamics of Hellmer (1989), this is
607        now the default
608      - give a few constants more intuitive names
609    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
610      if bulk formulae are used in long integration (especially EmPmR). Turn
611      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
612      if balancePrintMean, the imbalance that is substracted is printed to
613      STDOUT.
614    o fix bug (typo) in obcs_apply_eta.F
615    o add a new package shelfice which enables us to model the circulation
616      underneath shelf-ice with draughts of hundreds of meters.
617     - works
618     - to do: + include improved thermodynamics
619              + check whether kSurfC (from model/inc/SURFACE.h) can be used
620                instead of new field kTopC
621              + can we use topoFile, Ro_surf and existing code in ini_depth.F
622                instead of new field R_shelfIce and new code in ini_depth.F
623                and ini_mask_etc.F?
624              + adjust vertical mixing schemes?
625    o seaice pkg:
626     - add a cpp-flag to include a simple formula for a salinity dependent
627       freezing point of sea water at the surface
628     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
629       meridional stresses are now different (and hopefully correct)
630    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
631       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
632       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
633    o pkg/diagnostics: add options and parameters for regional-statistics
634       diagnostics ; define regions by reading a region-mask from a file
635       (might add other options later)
636    o pkg/bulk_force:
637     - add option and parameters to use AIM surface-flux formulae.
638     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
639       others forcing fields (defined in PARM05, parameter file "data") are loaded
640       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
641     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
642     - use the right EXCH call for uwind,vwind (to work on CS-grid).
643     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
644       and parameters (note: calcWindStress replaces .NOT.readwindstress).
645     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
646    
647    checkpoint58
648    o add "--embed-source" option to genmake2 which, when the supporting
649      tools can be compiled (as determined by genmake2) will turn on the
650      embed_files package which then embeds the entire MITgcm source code
651      (*.[fFhc] + Makefile) used for the build within the executable
652      - requested by CNH but off by default
653      - adds a paltry <9MB to the mitgcmuv executable in most cases
654      - only writes the output when useEMBEDSRC in eedata is true
655    o clean up 3-dim. relaxation codes:
656      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
657      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
658      * Thanks to Tom Haine for testing!
659    
660    checkpoint57z_post
661    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
662      affects output (@ truncation level) of exp. plume_on_slope ; updated.
663    o fix the pickup behavior for obcs in combination with ptracers
664    o fix a bug in ptracers_external_fields_load
665    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
666      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
667    o transfered surface NH pressure to eta field (if exactConserv).
668    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
669         and update lab_sea output.txt file.
670    o completing 3-dim. relaxation code: additional term
671         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
672      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
673      * At compile time, in "EXF_OPTIONS.h" set
674          #define  ALLOW_CLIMTEMP_RELAXATION
675          #define  ALLOW_CLIMSALT_RELAXATION
676      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
677          tauThetaClimRelax3Dim = 15552000.0,
678          tauSaltClimRelax3Dim  = 15552000.0,
679      * 3 cases:
680          1) Use a constant-in-time 3-dim. field
681          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
682          3) Real-time relax. to time-evolving prescribed field
683    o Adding Laplacian-type smoothness constraint on
684      initial and boundary (forcing) controls (ic, bc)
685      * enable at compile-time via
686        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
687      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
688      * Absolute scale somewhat unclear so far
689      * no area weighting was included since no other cost term does so far
690    
691    checkpoint57y_post
692    First step for a NLFS adjoint
693    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
694    o new init. routines for calc_r_star, calc_surf_dr
695    o still need to deal with ini_masks_etc
696    o testreport seemed happy
697    checkpoint57y_pre
698    
699    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
700    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
701    o add new offset feature to offline pkg (plus minor cleanup)
702    o cfc fixes for final year of integration
703    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
704      be in GCHEM_OPTIONS).
705    
706    checkpoint57x_post
707    o fix testreport Pb in multiple test experiment.
708    o cleanup our namelist syntax in verification:
709      - make it more F95 standards compliant (some work still needed)
710      - allows the vast majority of our tests to work with gfortran
711    o Non-Hydrostatic:
712     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
713     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
714    o Allow to apply AB on T,S rather than on AB(gT,gS):
715     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
716     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
717       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
718     - need a "clever" read_pickup to restart from the other AB formulation
719    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
720    o remove some unused variables (reduces number of compiler warnings)
721    o adjoint
722      * Disable useVariableViscosity for adjoint for time being
723        (there are a number of extensive recomputations)
724      * Initialize certain variables needed for adjoint
725    
726    checkpoint57w_post
727    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
728                 fix the singleCpuIO RS version of MDSWRITEFIELD
729       and add a WARNING if using globalFiles=T with multi-processors.
730    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
731      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
732    o tracer advection scheme:
733      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
734       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
735       was not very convenient).
736      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
737       (further tests needed for the implicit DST & Flux-Limiter schemes).
738    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
739      and sRef for convenience, handy, when you want to initialize
740      ptracers in a large domain with a constant non-zero value. Also,
741      untangle ptracers_init.F a little.
742    
743    checkpoint57v_post
744    o change dome exp. to use variable viscosity in side-drag terms.
745    o remove all the files from the cfc_offline test since they are now
746      incorporated into tutorial_cfc_offline which has been producing
747      identical results for a few days of testing
748    o add new parameter: sideDragFactor to enable half-slip-side BC
749      and change side-drag S/R to use viscosity from mom_calc_visc
750      (can switch back by setting sideDragFactor=0.); affects results at
751      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
752       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
753    o vorticity & strain are now computed without masking, to account for
754      no-slip-side BC in variable viscosity calculation ; mask is applied
755      anyway later on, before computing advection/coriolis terms.
756    o modify exp4 to test new obcs support for reading from external files
757      and for passive tracers
758    o fix behavior of ptracers_monitor when monitor output is written to a
759      netcdf-file; still not independent of monitor.F (writes in the same
760      file).
761    o change default value of tRef (put a uniform, meaningful value for ocean
762      & atmos) and initialize sRef (was missing, as Martin mentioned).
763    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
764      to be proportional to enstrophy dissipation length.  Thus,
765       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
766      This is now consistent with Smagorinsky and with the manual.
767    
768    checkpoint57u_post
769    o OBCS and PTRACERS: add open boundary support for passive tracers
770      - either use homogenous (pseudo) v.Neumann conditions or prescribe
771        OB-values from file; this is not different from the way theta and salinity
772        are treated
773      - however, Orlanski-radiation conditions are not supported, and the model
774        will stop if you use pTracers and Orlanski at the same time.
775      - beefed up the rountine obcs_external_fields_load: now only those open
776        boundary values are overwritten with values from files for which there
777        are really files, otherwise the OB-fields remain untouched. This makes
778        it possible to use different OBs at different ends of the domain (as
779        with EXF)
780    o reduce number of exch calls in shap_filt (s2).
781    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
782      truncation level) 4/5 MLAdjust test results (11&12 digits match).
783    
784    checkpoint57t_post
785    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
786    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
787      same truncation, independent of the face number: affects affects several
788      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
789    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
790      note that biharmonic viscosity + no-slip was not tested in any experiment.
791    o fix bug in non-linear free-surf side-drag ; generate new output for
792      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
793    o make mnc honor the writeBinaryPrec flag for most kinds of output
794    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
795    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
796      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
797    o add brackets in multi-terms sum to get same truncation, independent of
798      the face number (manage to get exactly same value of gU,gV at the cs-edge)
799      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
800    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
801      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
802      a maximum grid-scale Reynolds number.  Also, changes all length calculations
803      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
804      Suggested values of viscosity parameters found in mom_calc_visc.
805      Many new viscosity diagnostics available.
806    
807    checkpoint57s_post
808    o Add clearing-house for viscosity calculations, mom_calc_visc and
809      correct numerous bugs in LeithD and Smagorinsky discretizations.  
810      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
811      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
812      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
813      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
814      The Strain-Tension form is now called with useStrainTensonVisc=.true.
815      ViscAhStrain and viscAhTension are now retired.
816    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
817    o In response to JMC's bug report, genmake2 now ignores any soft-links
818      that it finds in the *current* directory when searching for files.
819      Soft-links found in any other source directories will still work as
820      they did before.
821    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
822      a C routine to unlimit the stack size
823    o mnc-ify pkg/aim snapshot vars
824    o mnc-ify pkg/land as requested by Daniel
825    o various changes to mnc including:
826      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
827      - output can now be grouped so that all files within a group
828          change the ITER portion of their names in lock-step together
829      - can now read ("global") PER-FACE (in addition to PER-TILE) files
830          and works with both EXCH1 and EXCH2 (but needs more testing)
831      - writing works for all verification test cases w/ g77 on Linux
832    
833    checkpoint57r_post
834    o make MNC variable initialization happen earlier
835    o add diagnostics for (almost) each term of the momentum Eq.
836    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
837    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
838    o remove MINIMAL_TAVE_OUTPUT option ;
839      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
840    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
841      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
842    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
843    o add time-dependent SST, SSS control
844    o cost terms in ecco/ modularized (new cost_generic.F)
845    o cost_averages routines are modularized (new cost_averagesgeneric.F)
846    o new infrastructure for seaice model vs. obs misfits in seaice/
847      * driver from the_main_loop.F is seaice_cost_driver.F
848      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
849      * gradient check in Exp. 6a of natl_box_adjoint/
850    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
851      (see README file)
852    
853    checkpoint57q_post
854    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
855    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
856      - bug was reported by Jean-Michel and Ian Fenty
857    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
858      update exp. cpl_aim+ocn output.
859    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
860      Needed for high-res. runs with large global files
861      to be able to limit tapelev size
862    o Changed some tests for adjoint:
863      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
864      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
865      * global_ocean.90x40x15/ back to default 3-level checkpointing
866    o Modifications to enable scripted COMMON to MODULE conversion
867      * verification/OpenAD/code/ has necessary scripts and description;
868      * converts, compiles and runs successfully;
869    
870    checkpoint57p_post
871    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
872    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
873      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
874    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
875    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
876      (was already the case for dissipation with mom_vecinv,
877       and also the case for grad.PhiHyd when staggered-timeStep)
878      This will allow to put dissipation out-off the AB time-stepping.
879     Unfortunately, affects truncation error. Update output of exp. that "fails"
880      (cg2d matching number) and leave the others for later: front_relax(10),
881      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
882      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
883    
884    checkpoint57o_post
885    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
886      (2) its ready to be documented during the 20050801 DocFest
887    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
888      for ideal_2D_oce and lab_sea on linux_ia32_g77
889    o set to #undef CTRL_SET_OLD_MAXCVARS_30
890      in global1x1_tot/code_seaice_adj to access indices 32, 33
891      (worth another tag)
892    
893    checkpoint57n_post
894    o adding precip control xx_precip 32
895    o adding swflux control xx_swflux 33
896    o Replacing 10 forcing penalty cost routines by 1 generic.
897    o Implementing partitioning in time-mean and variable adjustment
898      for atmos. state.
899    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
900    o in natl_box_adjoint:
901      * updated exp 1 to 10
902        (but does not have time-mean vs. variable split results yet)
903    o updated global1x1/*_seaice_adj/
904      to incorporate latest changes
905    o enable useSingleCpuIO for mdsio vector routines
906      (applies in particular to tapelev I/O)
907    o removed inefficient K-loop in all active_file*control*.F
908    
909    checkpoint57m_post
910    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
911      and advect_cs (use EXCH-2 and standard cs-32 grid files).
912    o pkg/exch2: filling of face-corner halo regions is optional
913      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
914    
915    checkpoint57l_post
916     tag before updating tutorials (pre-release-2)
917    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
918       for output and interpolation of input fields onto model grid)
919    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
920       Affects results of exp. rotating_tank ; update output.txt.
921    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
922          and taking the square quantity and/or using a fraction-weight field.
923    o fix aim_diagnostics_init.F mate numbers.
924    o add mnc output capability to diagnostics/diagstat and update
925      our cvsignore files for the ACSII output generated
926    
927    checkpoint57k_post
928    o lab_sea now uses diagnostics package and provides a suite of
929      new EXF diagnostics output.
930    
931    checkpoint57j_post
932    o exf
933      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
934        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
935        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
936      * extended diagnostics output
937        - now includes all EXF variables
938        - hs, hl moved to common block
939        - separate S/R for diagnostics, called after ctrl vector is added
940        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
941        - EXFqnet contains true Qnet (i.e. includes qsw)
942      * updated verif. lab_sea, global_with_exf
943      * Rearranging hflux (exf_mapfields -> exf_getforcing)
944        to ensure that diagnostics sees a true EXFqnet
945    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
946    o diagnostics pkg: change pointers so that 1 diagnostic can be used
947      several times with different frequencies.
948    o mnc-ify the thsice package as requested by Daniel Enderton
949      - the monitor--MNC output needs work
950      - many attributes need to be added (most are currently blank)
951    o mnc-ify theaim_v23 package as requested by Daniel Enderton
952      - many attributes need to be added (most are currently blank)
953    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
954    o add Sadourny like discretization to the 4th.O vorticity advection scheme
955    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
956      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
957         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
958    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
959     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
960    
961    checkpoint57i_post
962    o Diagnostics package was changed: diagnostic allocation is now deactivated
963      by setting an empty file name in the namelist (used to be by setting 0 frequency)
964    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
965      add 1rst Order upwind vertical Shear.
966    o add a quick fix for A/B checkpointing in OFFLINE mode
967    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
968      end-run around the C/Fortran linking horror in eesup/src/timers.F
969    o added pkg/runclock: allows user to terminate run based on wall clock
970    o added non-hydrostatic scaling parameter: nh_am2
971    o pkg/my82: futile attempt to make results compiler-independent by adding
972      some "_d 0", etc. no effect.
973    o for mnc output, fill the 'T' coordinate var with myTime and create a
974      separate 'iter' variable for iteration count
975    o pkg/diagnostics:
976      add new capability: output of Global/Regional & per-level statistics ;
977      tested against monitor output (including land & thSIce) on various exp.
978    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
979    
980    checkpoint57h_done
981      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
982      data.diagnostics, data.gchem, data.ptracers) is done.
983    
984    o pkg/diagnostics: prepare for Global/Regional statistics.
985      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
986    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
987      and rename it: DIFFERENT_MULTIPLE
988    
989    checkpoint57h_post
990    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
991    o pkg/diagnostics: change output frequency, now in seconds (instead
992      of Nb of iterations). This requires to change data.diagnostics.
993    checkpoint57h_pre
994    
995    o in mnc, let the user create the output dir if both mnc_outdir_date
996      and mnc_outdir_num are false
997    o add fflags() to pkg/diagnostics which allows one to specify, on a
998      per-file basis, the file precision [default behavior is unchanged]
999    o added diagnostics to pkg/kpp, including computation of mixed layer
1000      depth based on a temperature/density criterion
1001    o updated verification/natl_box to test the new pkg/kpp diagnostics
1002    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1003    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1004    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1005      not mnc -- this mistake was found by JMC and is now corrected
1006    
1007    checkpoint57g_post
1008    o add Adams-Bashforth 3rd Order time stepping:
1009      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1010      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1011    checkpoint57g_pre
1012    
1013    o make lambda[Theta,Salt]ClimRelax spatially varying
1014      (default remains spatially uniform constant based on tau)
1015    o added new control variables
1016      * init. uVel, vVel, etanN
1017      * lambda[Theta,Salt]ClimRelax
1018    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1019      (suggested by G. Forget)
1020    
1021    checkpoint57f_post
1022    o add parameter "baseTime" = model base time = time at iteration zero
1023      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1024      account for baseTime shift
1025    o move Coriolis arrays from PARAMS.h to GRID.h
1026    checkpoint57f_pre
1027    
1028    o mnc-ifying the seaice package
1029    o introduced an alternative length scale calculation for use in the limiting
1030      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1031    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1032    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1033      as well as grad(vort3).  Made it compatible with both approximate form
1034      for the cubed sphere and full form of these gradients.  Added flag
1035      useFullLeith to select between approximate and full form.  
1036    o add "d0" in getcon.F to reduce differences between compilers/platforms
1037      update output.txt of exp. fizhi-gridalt-hs
1038    o change port_rand funtion to allow to set the seed.
1039    o fix obscure MNC bug involving conversion between reals and integers
1040      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1041        new version is now more standards-compliant
1042    o adjoint-related modifications
1043      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1044      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1045      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1046    
1047    checkpoint57e_post
1048    o Adding eddy stress controls a la Ferreira et al.
1049    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1050    
1051    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1052      update output.txt of exp. fizhi-gridalt-hs
1053    o add more "Z" dimensions and associated coordinate vars to MNC
1054    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1055    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1056      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1057      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1058      months and years.  Requires pkg/cal.
1059    o diagnostics: add pickup functionality
1060      - off by default for backwards compatibility
1061      - current version only uses MDSIO -- MNC will be added
1062    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1063    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1064    
1065    checkpoint57d_post
1066    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1067    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1068      output from the diagnostics package
1069    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1070    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1071      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1072    o add coordinate variables to the MNC output from the diagnostics package
1073    o change MNC-flags default value: true when useMNC=TRUE
1074    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1075      the ability (off by default) to read the grid information using MNC
1076    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1077    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1078    o do snap-shot diagnostics at the middle of the time-interval (instead of
1079      at the end).
1080    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1081      new test for AIM with thSIce + slab-ocean
1082    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1083    o move state variable diagnostics to the beginning of the time step ;
1084      (note: still needs some work specially for snap-shot diagnostics)
1085      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1086    
1087    checkpoint57c_post
1088    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1089    o generate new output.txt files on faulks with g77 & the new -ieee option
1090    checkpoint57c_pre
1091    
1092    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1093      update output.txt of exp. global_ocean.90x40x15
1094    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1095      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1096    o add saltFlux(+File) forcing capability with periodicExternalForcing
1097    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1098    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1099    o improvements for the MNC output from DIAGNOSTICS:
1100      - correct handling of the unlimitied dimension
1101      - all dims now have associated coordinate variables
1102      - variables located at U, V, and Corner ("Z") points are now written
1103        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1104        *all* data points are output
1105    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1106    o added pkg/seaice/seaice_monitor.F
1107    o mdsio_readfield.F can now read files visible only to master MPI process.
1108    o pkg/seaice: some test code for ice-modified ocean stress
1109    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1110      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1111      spurious negative numbers for precipitation and humidity.  Will cause
1112      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1113    o pkg/ctrl/
1114      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1115        May be enabled via doPackDiag
1116      *  introduce z-scaling of
1117         + gradient (doZscalePack) and
1118         + control (doZscaleUnpack)
1119    o pkg/mdsio/
1120      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1121      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1122    
1123    checkpoint57b_post
1124    o simplify options in diagnostics_fill arguments (remove weird combinations)
1125    o fix MNC coordinate variables so that they now contain per-face index
1126      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1127      general, EXCH2 grids are only aligned to a "local" coordinate system
1128    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1129    o Implement instantaneous output within pkg diagnostics:
1130      setting a negative frequency in data.diagnostics produces
1131     "snap-shot" output (as opposed to time-average if freq > 0)
1132    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1133      NOTE: change ptracer diagnostics name: use 2 characters to work with
1134            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1135    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1136      becomes the coordinate variable for the 'T' dimension
1137    o add CF-style coordinate variables to MNC
1138      - just a first cut:  numbers are meaningless on the cubesphere and
1139        missing along the T axis but otherwise it works!
1140    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1141    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1142    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1143      this is based directly on what the model compute, so that the content of
1144      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1145    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1146    o clean up build options files for SunOS, in particular
1147      - remove -traditional from xmakedepend
1148      - change -xarch=v9 to -xarch=native for f77
1149      - restore use of make (not gmake)
1150      - add CC=gcc if using g77
1151    o changes per discussion of AM, JMC, & EH3 today:
1152      - move redundant "grid" variables out of "state" -- in preparation of
1153        creating proper CF-style coordinate variables and in recognition
1154        that any/all grid variables can be easily copied (eg. w/NCO) from
1155        the grid files into any of the other NetCDF files
1156      - *always* output grid variables with MDSIO (this will eventually be
1157        changed)
1158      - output MNC grid file if useMNC is true
1159    o every instance of _END_MASTER() has been found and replaced with
1160      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1161      preprocessors
1162    o re-arrange diagnostics pkg initialisation:
1163     - allow each package to extend the available diagnostics list
1164     - add some checking and fix small problems (multi-threaded, ...)
1165     - new S/R diagnostics_fill (replace fill_diagnostics):
1166       look through the short list of active diag. (instead of the long list)
1167       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1168    
1169    checkpoint57a_post
1170    o this set of changes restores TAMC compatibility
1171      tested for global_ocean.90x40x15 adjoint on trough
1172      (what a pain)
1173    
1174    checkpoint57a_pre
1175    o some modifs in tools/build_options for sunos
1176    o call ctrl_pack for ctrl at end for optimcycle=0
1177    
1178    checkpoint57
1179    o add horizontal bi-harmonic viscosity for vertical velocity
1180      - new parameter viscA4W (defaults to viscA4)
1181      - affects only non-hydrostatic code
1182      - to be done: no-slip lateral boundary conditions
1183    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1184    o implement Implicit Vertical advection for pTracers
1185    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1186      (implemented also for implicit vertical diffusion & advection)
1187    o OBCS: extend application of tracer open boundary conditions
1188      to a strip beyond the boundary of width Olx/Oly
1189    o add call monitor to TAF set of required calls (flow directives)
1190      and include in natl_box_adjoint
1191    o untangle a few ifdefs related to cost, ctrl, autodiff
1192      untangel a few ALLOW_ECCO_OPTIMIZATION
1193    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1194      (theta2, salt2 in ecco_cost_weights)
1195    
1196    checkpoint56c_post
1197    o OBCS as control variables
1198      - update ctrl_ad_diff.list, obcs_ad_diff.list
1199      - remove balance of obcs controls from default
1200      - fix index bug nobcs in ctrl_init
1201      - fix dummy fields filen in ctrl_pack
1202      - add dummy weights for obcs
1203    o lsopt: comment out fort.94 output
1204    o optim:
1205      - remove unnecessary header files
1206      - adjusted namelists
1207      - add xerbla.F to Makefile
1208    o exf:
1209      - multiple modifications of exf_check_range
1210      - unit change in exf_init_runoff from [m/year] to [m/s]
1211    o mdsio:
1212      - i/o-vector change debugLevel from debLevA to debLevB
1213    
1214    checkpoint56b_post
1215    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1216      is called from DO_THE_MODEL_IO
1217      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1218      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1219      - clean up PTRACERS_WRITE_TIMEAVE a little
1220    o add another verification experiment that tests both the cfc-pkg and
1221      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1222      reactive tendencies treated inline with regular timestepping
1223    o testreport previously did a lousy job of comparing small numbers, so
1224      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1225      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1226      testreport.
1227    o ptracers_monitor: bug fix for MPI
1228    
1229    checkpoint56a_post
1230    o GCHEM: finish reorganizating the package
1231      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1232        (introduces another 3D-array for each passive tracer, but only if
1233        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1234        gchemTendency is not needed because the timestep is done separately)
1235      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1236      - GCHEM is now---more or less cleanly---separate from PTRACERS
1237      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1238        so clear to me how that should be done in a general way.
1239    o CFC: improve formatting of output in CFC_ATMOS
1240    o PTRACERS:
1241      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1242        that ALL experiments with ptracers enable can be checked. This makes
1243        GCHEM_MONITOR obsolete.
1244      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1245        monitorFreq
1246      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1247    o add PTRACERS (PTR0[1-5]) to testreport output
1248    o exf_check_range:
1249      * default changed to .TRUE.
1250      * will check values for niter0 if debLevA, every timestep if debLevB
1251      * STOP in exf_check_range if 'out of range'
1252      * range chosen generous to allow for potential extema
1253      TBD: a version with stricter range
1254           permitted range would be runtime parameters
1255    o GMredi:
1256      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1257      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1258      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1259    o GCHEM:
1260      - move call to GCHEM_FORCING_SEP, so that it is now called before
1261        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1262      - introduced a useGCHEM runtime flag and applied it everywhere.
1263      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1264        this flag is now only visible within GCHEM-pkg routines.
1265      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1266        be replaced by a 3D array that is computed before thermodynamics; for
1267        this, the tracer ID iTracer had to be included into the parameter list
1268        of ptracers_forcing
1269      - set up forward_step to call gchem_forcing, that will replace
1270        gchem_forcing_int in ptracers_forcing
1271      - cleaning up
1272    o small cleaning of exch2: remove files that are also in eesupp/src
1273    
1274    checkpoint56
1275    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1276    o mnc: cleanup "full" files--fixes out-of-memory problem
1277    o ECCO-GODAE
1278      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1279      * fully merged and updated from SIO code
1280        windstress sign change affects
1281        - exf_inscal_[u/v]stress
1282        - sign of xx_tau[u/v] adjustments
1283        - signs in cost_scat
1284      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1285      * natl_box_adjoint updated and compressed
1286      * 2-level checkpoint switch added
1287        (tested in EXP. 1 of natl_box_adjoint)
1288      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1289    o SVD
1290      * first complete, non-hacked version for SVD calculations
1291      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1292        performed via direct access files admtlm_vector.it????
1293        (via ctrl_[un]pack)
1294      * optimcycle is used for ARPACK iteration counter
1295        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1296      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1297        and add linear transforms where necessary
1298      * controls are initial/final SST, SSS (can be extended; need to check
1299        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1300    o mdsio: filename info to both stderr, stdout
1301    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1302      from sign change
1303    
1304    checkpoint55j_post
1305    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1306      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1307    o add consistent build directories and .cvsignore files to verification
1308    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1309    o make all subroutines 30 or less characters in length for certain older
1310      compilers to work (a thorough search only turns up two routines in
1311      pkg/ptracers)
1312    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1313      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1314    
1315    checkpoint55i_post
1316    o change arrays for total vertical diffusivity (2.D if explicit,
1317      3.D if implicit) ; each ptracer uses its own background value.
1318    o added mnc/NetCDF output capability to ocn_compon_interf
1319      - added bits to verification/cpl_aim+ocn so that it can run on
1320        ITRDA and other clusters without the mpirun "-wd" option
1321    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1322      configuration
1323    o give MNC the ability to create additional files rather than
1324      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1325      - the default is just less than 2GB which is a practical limit
1326        on many systems
1327    o Compute the non-local term using either KPP vertical diffusivity (=default)
1328       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1329    
1330    checkpoint55h_post
1331    o add verification test "vermix"
1332    o remove all the *_ioinc flags and replace with the single global
1333      outputTypesInclusive flag
1334    o allow to set a vertical profile of vertical diffusivity for T & S
1335    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1336    o useMNC moved from data.mnc to data.pkg
1337    
1338    checkpoint55g_post
1339    o Renaming carbon AD experiments to comply with testreport conventions
1340    o Updating adjoint of Held-Suarez hs94.1x64x5
1341    o Fixing directives for non-ECCO forward_step, after ECCO directives
1342      have been fixed to avoid recomp. of do_oceanic_phys
1343      Works well for global_ocean.90x40x15,
1344      but recomp. issue remains for carbon
1345    o Updating adjoint output for natl_box_adjoint after
1346      pkg/ecco has been modified (see taga c55d_post)
1347    
1348    checkpoint55f_post
1349    o rename to timeave_init_fixed
1350    
1351    checkpoint55e_post
1352    o some delicate re-shuffle of store directives to avoid one
1353      extra call of do_oceanic_physics
1354      affects ecco_the_main_loop.F, do_oceanic_physics.F
1355      checkpoint_lev1_directives.h
1356    o NB: this may break global_ocean adjoint temporarily,
1357      but it is clear how to fix it. Will do later, need this now.
1358    
1359    checkpoint55d_post
1360    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1361    o ecco_cost_weights is modified to 1x1 runs
1362    o modifs to allow observations to be read in as
1363      single file or yearly files
1364    o enable to read exf forcing fields as either
1365      single file or yearly files (flag useExfYearlyFields)
1366    checkpoint55d_pre
1367    
1368    o switch between 2-level and 3-level checkpointing
1369    o add ability of MNC to write local and "partial" (eg. 2D slices where
1370      the full 3D field is never actually stored) arrays to NetCDF files
1371      with the correct (that is, the complete multi-dimensional) set of
1372      array indicies
1373      - used in mom_vecinv() to write the diagFreq output
1374      - tested (demonstrated) in verification/aim.5l_cs
1375    o further mnc-ification
1376      - add verification/lab_sea to the list with mnc setups
1377      - fix undefined mnc v-names in cd_code
1378      - add kpp to mnc output (both snapshot and timeave)
1379    o non-hydrostatic code
1380      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1381        in calc_gw.F
1382      - defaults to viscAh
1383      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1384        friction or Leith) in non-hydrostatic mode, as long as there is
1385        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1386    o pkg/cost
1387      extend simple cost functions to treat time mean quantities
1388      (T,U,V) via cost_accumulate_state from cost_tile
1389    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1390        be 2 times larger than the minimum size the advection scheme requires.
1391        now get a perfect conservation of salt in advect_cs test-exp (updated)
1392    o GGL90 (Gaspar's TKE mixed layer)
1393      - add horizontal diffusion of TKE, requires exchanges in
1394        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1395        default. In OPA there is no horizontal diffusion of TKE but the
1396        mixing coefficients are computed from a horizontal average of TKE of
1397        6 points or so. I think that diffusion has a little more physical
1398        justification.
1399      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1400        was in vain)
1401      - mask tke-variable in ggl90_init
1402    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1403    o fix biharmonic diffusion on CS-grid.
1404    o more obcs stuff
1405      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1406        for reading boundary values. This routine is called from
1407        obcs_prescribe_read
1408      - updated obcs_check
1409      - changed sponge layer relaxation parameter units for days to seconds
1410      - turned off sponge layer by default
1411      - changed argument list of OBCS_CALC to myTime+deltaTclock
1412      - fixed about 35 bugs in obcs_external_fields_load
1413    
1414    checkpoint55c_post
1415    o obcs stuff
1416      - new runtime flags useOBCSprescribe, useOBCSbalance
1417      - re-arranged obcs_calc
1418      - moved exf_getobcs to obcs_prescibe_read
1419        obcs_prescibe_read is called after ORLANSKI stuff
1420        and independent of it (executable can contain all).
1421      - updated obcs_check
1422      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1423        These may be necessary only if tangential velocities are
1424        prescribed at OB, not sure, needs testing.
1425    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1426      which simplifies the calls and passes the ifc check-bounds test
1427    
1428    checkpoint55b_post
1429    o add a 2D scalar, Z location, exchange_2 routine.
1430    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1431      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1432      affects advect_cs results (for the wrong reason): update output.txt
1433    o use a more standard discretization for biharmonic viscosity ;
1434     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1435      affects results of dome set-up: update output.txt
1436    o fix gad_advection.F (CubedSphere part), back to version 1.23
1437    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1438    
1439    checkpoint55a_post
1440    o merged code to
1441      * prescribe/read time-dependent open boundaries
1442        (works in conjunction with exf, cal)
1443      * sponge layer code for open boundaries
1444      * each boundary N/S/E/W now has its own CPP option
1445        (healthy for the adjoint)
1446    
1447    checkpoint55
1448    o up-to-date adjoint of previous breaks
1449      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1450      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1451      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1452      - carbon: * remove tr1-related adjoint verification
1453                * add ptracer as control variable
1454    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1455      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1456    
1457    checkpoint54f_post
1458    o in verification/carbin/ remove experiment related to
1459      ALLOW_PASSIVE_TRACER (array tr1 etc)
1460      code_ad/ input_ad/ results_ad
1461    
1462    o add two new packages
1463      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1464        + subject to optimization (memory)
1465      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1466        + subject to reordering (many GOTOs in the original code)
1467        + so far opps is called for every (i,j) point, and then operates in
1468          the vertical; one may want to reorder the scheme in order operate in
1469          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1470          fields)
1471    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1472      - all verification tests compile and run with linux_ia32_g77
1473      - defaults are compatible with current input files--nothing
1474        should change if you were not previously using MNC
1475      - MNC output has been added in numerous places (eg. timeave)
1476        but there are still a few writes not yet do-able with MNC
1477        (this is in progress)
1478      - flags now allow for either/or/both use of MDSIO and MNC and
1479        documentation will soon follow
1480      - numerous small formatting cleanups for ProTeX
1481    o add version info (via BUILD_INFO.h) to MNC and stdout
1482    
1483    checkpoint54e_post
1484    o add two new packages
1485      - pp81 (Packanowski and Philander, 1981), Richardson number and
1486        stratification dependent mixing
1487      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1488      - these scheme operate in a similar manner as KPP (without ghat, of
1489        course), however there is only one diffusivity that is used for both
1490        temperature and salinity (and passive tracers)ç
1491    o add offline package
1492    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1493      provided by Stephanie Dutkiewicz
1494    o genmake2: add ability to search for C compilers and cleanup test output
1495      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1496    
1497    checkpoint54d_post
1498    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1499    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1500      leading to additional shift by 5 days each year of integration
1501       (i.e. leading to considerable offset over the years)
1502    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1503    o start with no AB and no initial filtering (staggerTimeStep):
1504      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1505    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1506      (external loading & cpl import/export stay in forward_step.F)
1507    o update coupling interface to work with new staggerTimeStep
1508    o change MDSIO ptracers_pickup.
1509    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1510    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1511    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1512    
1513    checkpoint54c_post
1514    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1515      this affects (truncation error) output.txt of test-exp:
1516       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1517    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1518    o change Qnet to always be the net heat flux, (+upward).
1519      affects (truncation error) output of natl_box exp.: updated
1520    o define the max number of passive tracers in PTRACERS_SIZE.h
1521    o start to test mnc routinely in exp0
1522    o add sea-ice loading (sIceLoad) as a new forcing field.
1523    
1524    checkpoint54b_post
1525    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1526       impressive on Altix and Opteron systems)
1527    o diagnostics can now write NetCDF files through the mnc package
1528    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1529    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1530    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1531      affects (truncation error) output of lab_sea & natl_box exp.: updated
1532    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1533    
1534    checkpoint54a_post
1535    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1536    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1537    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1538    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1539      + internal_wave (shift in writing cg2d_ini_res)
1540    checkpoint54a_pre
1541    
1542    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1543      - modified verification/lab_sea and natl_box_adjoint accordingly
1544    
1545    checkpoint54
1546    checkpoint53g_post
1547    o prepare splitting of thermodynamics: store convect.counter in common block
1548    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1549      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1550    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1551    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1552    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1553    o restore adjointability
1554    
1555    checkpoint53f_post
1556    o modifications that affect AIM experiment results (update output.txt):
1557      - no advection of S at top interface Nr (pkg/generic_advdiff)
1558      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1559    o AIM pkg:
1560      - include stability function into surf.Flux derivative relative to Tsurf
1561      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1562    
1563    checkpoint53e_post
1564    o merged cylindrical coord configuration
1565    o added rotating_tank experiment
1566    checkpoint53e_pre
1567    
1568    checkpoint53d_post
1569    o faulks upgraded: re-generate output.txt that have changed:
1570       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1571    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1572    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1573    o added Sadourny discretization of Coriolis
1574      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1575      - re-enabled use of omega3 (useAbsVorticity)
1576    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1577      vector-invariant equations
1578      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1579    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1580      hopefully without new bugs
1581      - still to do: biharmonic friction for non-hydrostatic w
1582    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1583    o regenerated output for global_ocean_ebm (using -ieee)
1584    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1585      of mom_common/
1586      - simple re-arrangement of instructions within computing loop
1587    checkpoint53d_pre
1588    
1589    checkpoint53c_post
1590    o new version of coupler for AIM+thSIce and Ocean models
1591     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1592     - land: change Evaporation of snow
1593     - aim with thSIce: fix bug in snow-precip.
1594    o changes to calc_gw.F
1595     - bug fix for w^2 term near the bottom boundary
1596     - (hopefully) improve the lateral slip boundary condtions for use with
1597        partial/looped cells
1598      - because the bug fix changes two verification experiments anyway (exp5
1599        and plume on slope), change the lateral boundary condition from half slip
1600        to the value of no_slip_sides
1601    o ebm package wasnt quite up to the parallel task. Fixed that.
1602    o Adjoint of EBM package + verification
1603      * TLM OK
1604      * ADM not sufficient accuracy yet (needs further testing)
1605    
1606    checkpoint53b_post
1607    o Commiting new energy balance model to repository
1608      * package is pkg/ebm
1609      * verif. is verification/global_ocean_ebm
1610      * references are in ebm_driver.F
1611    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1612    C        Global thermohaline circulation. Part I:
1613    C        Sensitivity to atmospheric moisture transport.
1614    C        J. Climate 12(1), 71-82
1615    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1616    C        Global thermohaline circulation. Part II:
1617    C        Sensitivity with interactive transport.
1618    C        J. Climate 12(1), 83-91
1619    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1620    C        Destabilization of the thermohaline circulation
1621    C        by atmospheric eddy transports.
1622    C        J. Climate 7(12), 1870-1882
1623    o Will need long integration testing.
1624    checkpoint53b_pre
1625    
1626    o created pkg/mom_common in preparation for variable viscosity code
1627    o renamed and split ini_mnc_io
1628    o pkg/land: only liquid water can diffuse or run-off
1629    o AIM using land: soil wetness availability account for snow
1630    o added printMapIncludesZeros to EEPARMS namelist
1631    
1632    checkpoint53a_post
1633    o restore TAMC compatiility for exf_constants.h
1634      (no usage of _d in .h)
1635    o Additional storing in KPP in an attempt to fix
1636      TAMC problem with adjoint of KPP code.
1637      (no success...)
1638      Identical code works fine with TAF.
1639    o Fixed verification/natl_box_adjoint experiments.
1640      Initial conditions for Experiments 4 and 5 are now
1641      set to "SEAICE_initialHEFF=0", which is more reasonable,
1642      and hence gives results closer to that of Experiment 2.
1643      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1644    
1645    checkpoint53
1646    o stable checkpoint with up to date adjoint
1647      TLM tests only run for 1st grdchk at the moment. Its unclear if
1648      this is a code problem or a problem with resetting code for g_
1649      variables that is being autogenerated wrong.
1650      Otherwise:
1651       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1652       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1653         are both still in chaos following their security messes.
1654    
1655    checkpoint52n_post
1656    o various build (mostly genmake2) changes including:
1657      - ability to build/run more easily within Cygwin and MacOS X
1658      - more complicated Makefiles with a stronger dependence on Gnu Make
1659    o pkg/seaice modifications
1660      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1661        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1662        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1663      - changed proxy for geostrophic velocity and updated
1664        verification/lab_sea/results/* accordingly
1665      - removed ADI dynamic solver from pkg/seaice
1666      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1667        they caused a segmentation fault under certain circumstances
1668      - removed unused field WATR
1669    o bug fix in exf-package:
1670      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1671         now reflect that.
1672    o small fixes in the cal-package:
1673      - set reference date to first of January for the 'model'-calendar
1674      - failing of cal_CheckDate in cal_FullDate now actually results in a
1675        warning
1676    o small modifications in exf-package to increase flexibility:
1677      - change climtempfreeze from a constant to a runtime parameter that
1678        is specified in data.exf_clim (default = -1.9)
1679      - introduce runtime parameter windstressmax (default = 2.0) that is
1680        specified in data.exf
1681    o fix in pkg/thsice:
1682      - update Evap (Tsf changes) to be consistent with Latent heat flux
1683      - maintain snow precipitation unchanged (even if Tsf >=0).
1684     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1685    
1686    checkpoint52m_post
1687    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1688      this does not change any of the results, because myIter=0 in swfrac always
1689      lead to jwtype=2 (the default anyway), but the call makes little sense
1690      as a default
1691    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1692    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1693      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1694    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1695    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1696    o extending useSingleCpuIO option to work with new exch2 I/O format
1697      - old-style, missing-tile I/O is still accessible by defining CPP
1698        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1699    o monitor package can write to NetCDF files and/or STDOUT
1700    o fix re-definition bug in MNC_GRID_INIT_ALL()
1701    o doc/api_reference added
1702      - a framework for building an API Reference Manual using all
1703        the "protex" comments embedded in the code
1704      - see pkg/generic_advdiff, pkg/mnc for examples
1705    o MNC:
1706      - make myThid the last argument for all subroutines
1707      - new default for the grid files: NO halos
1708      - add useMNC and other run-time flags
1709      - separate per-file-group handling of the unlimited dimension
1710      - early initialization of MNC w/ flags read at the eeboot stage
1711        and lookup tables set in initialize_fixed
1712      - write all MNC output to a freshly-created directory
1713    o thermodynamics sea-ice (thsice) is now tested with testreport.
1714    o test exp. advect_cs: use the standard cs32 grid ; update output.
1715    o Added functionality to grdchk:
1716      pick global i,j,k position (or nearest wet) where to perform check.
1717    
1718    checkpoint52l_post
1719    o new land formulation:
1720      a) use ground enthalpy as prognostic variable to ensure exact
1721         energy conservation.
1722      b) account for water temperature and for latent heat of freezing
1723         in all processes (rain, run-off, ground storage)
1724      c) compute surface and ground temperature implicitly.
1725    o aim_v23 modification for new land model:
1726      a) Treat separately land / ocean / sea-ice surface fluxes
1727         to allow implicit computation of land & sea-ice surface temp.
1728      b) add snow precipitation.
1729    checkpoint52l_pre
1730    
1731    o fix problem (when 1 tile is empty) in min/max monitor.
1732    o fix bug in timeAve (u,vZetatave in common block)
1733    o no restoring terms under ice for pkg/seaice
1734    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
1735    o bug fix for pkg/seaice pickups
1736    o change MNC call locations and add coordinate attributes
1737    o mask vorticity at the corner ; affects global_ocean.cs output
1738    o fix ini_curvilinear_grid ; test CS experiments with mpi
1739    o aim.5l_cs: modify sea-ice fraction input file ; update output
1740    o exf: Adding simple range check routine for exf fields after read
1741    
1742    checkpoint52k_post
1743    o removed top-level directory "diags"
1744      - we migrated these functions to pkg/timeave a long time ago
1745    o fixed bug introduced in pkg/monitor
1746    o accuracy ctrlprec = 32 insuffient for gradient checks using
1747      averaged fields (I/O via cost_averages)
1748      -> use ctrl.h in active_file*.F to control I/O precision.
1749    o paramter list of CALL ADTHE_MAIN_LOOP
1750    o added initial do_the_model_io to ecco
1751    o set all ...Freq to zero after cost_final
1752      taveFreq, dumpFreq, pChkptFreq
1753    o MAIN and ECCO differentiability restored
1754    
1755    checkpoint52j_post
1756    o fix nchklev in tamc.h for global_ocean...
1757    o Bringing flow and store directives up-to-date
1758    o Really weird thing!
1759      call do_the_model_io from the_main_loop with parameters
1760      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1761      TAF places a faulty re-call of initialise_varia
1762      after cost_final call which should not be there!
1763    checkpoint52j_pre
1764    
1765    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1766      error messages
1767    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
1768    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
1769      debug output
1770    o modfied mdsio_writefield.F to handle non-global files under exch2
1771    o update AIM Cubed-Sphere exp (aim.5l_cs):
1772      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
1773    o update AIM Equatorial Channel exp:
1774      use standard aim_v23 pkg and change the SST fields to be more realistic.
1775    o globalFile now works with exch2
1776    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
1777      mon_vort3.F to make exch2 friendly with >1 tile per cube face
1778    o limit timeave output for hi-res integrations
1779    
1780    checkpoint52i_post
1781    o removed CPP_EEOPTIONS.h from verification/*/code
1782    o updated the tiling for global_ocean_pressure
1783    checkpoint52i_pre
1784    
1785    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
1786      the old pkg/aim).
1787    
1788    checkpoint52h_pre
1789    o shortened offending lines in exch2_send_rx?.template
1790    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
1791    o genmake2: add build & execute test for NetCDF code
1792    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
1793      old grid files, moved CPP_EEMACROS.h to pkg/exch2
1794    o added useSingleCPUIO flag to monitor.F and mon_out.F
1795    o added temporary hack for sea-ice dynamics on the cube:
1796      metric terms are ignored and it is assumed that
1797      there is no sea-ice on cube faces 1, 2, 4, and 5.
1798    
1799    checkpoint52f_post
1800    o added exch2 cube routines to pkg/exch2
1801    o modified hs94.cs-32x32x5 to use it
1802    o added new grid files to hs94.cs-32x32x5
1803    checkpoint52f_pre
1804    
1805    checkpoint52e_post
1806    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
1807      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1808    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1809      to work with implicit vertical advection and AB ;
1810    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1811    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1812     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1813    checkpoint52e_pre
1814    
1815    o fix bug in impldiff when Nr=1 or Nr=2.
1816    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1817    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1818    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1819      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1820    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1821    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1822    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1823    
1824    checkpoint52d_post
1825    o re-tiled many expts to allow comparison in multi-processor mode
1826      - updated output accordingly
1827      - changed hs94.128x64x5 to use intial T from file rather than use the
1828        random number generator
1829    o add infrastructure in model routines for fizhi and gridalt packages
1830    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.

1833      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1834      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1835        of surface winds for the cube
1836      (A verification experiment, based on global_ocean.cs32x15, but with
1837       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1838       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1839       complete with example surface forcing files and matlab scripts to look
1840       at the output and compare it with that of global_ocean.cs32x15.)
1841    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1842       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1843       to conform to the common rule.
1844    o check-in the first version of the coupler + interfaces for multi-components
1845       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1846       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1847       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1848       - ocean and atmos. share the same horizontal grid (no interpolation).
1849       - exchanges between component and coupler is done in forward_step
1850    o new verification experiment, cpl_aim+ocn:
1851       coupled ocean - AIM atmosphere on cs32 grid.
1852    
1853    checkpoint52d_pre
1854    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1855    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1856    
1857    checkpoint52c_post
1858    o Fixing OPTIONS files for use of exf:
1859      - ALLOW_ECCO not needed
1860      - ECCO_CPPOPTIONS.h should not be included from
1861        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1862        as has been the case in the past
1863      - All cal/exf related options are currently set in
1864        single header file. Should remain so until we
1865        agree on a consistent new policy.
1866    o Removed all CPP options for cal package.
1867      cal has no more CPP options.
1868    o modified STOREs in GAD_ADVECTION
1869    o corrected key comp. for passkey
1870    
1871    checkpoint52b_post
1872    o new version: "thsice" of thermodynamic sea-ice pkg:
1873     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1874     - modify fluxes but do not change theta directly;
1875     - light cleaning of bulk_force pkg (still needed with thsice).
1876     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1877       + output_thsice.txt to test thsice & bulk_force pkgs.
1878    o put back grid & coriolis monitor output.
1879    checkpoint52b_pre
1880    
1881    o call "do_the_model_io" at the beginning (=> dump initial state)
1882    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1883    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1884      (need info on NUMBER_OF_PTRACERS)
1885    o missing PTRACERS headers in some routines
1886    o default tamc.h in pkg/autodiff supposed to crash
1887      to ensure proper customization
1888    
1889    checkpoint52a_post
1890    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1891      - moved surfaceTendencyTice from pkg/seaice to main code
1892      - subroutine FREEZE_SURFACE now limits only surface temperature
1893        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1894        => new output.txt for global_ocean.cs32x15 & global_with_exf
1895      - keep the old version of FREEZE for backward compatibility;
1896        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1897      - corresponding modifs for TAF directives
1898    o added surface flux output variables to TIMEAVE_STATVARS

1902      but no warning issued by TAF
1903    
1904    checkpoint52a_pre
1905    o some bug fixes for #undef REAL4_IS_SLOW
1906    
1907    checkpoint52 = ecco_c52_e35
1908    o after testing adjoints of checkpoint51u_post
1909    
1910    checkpoint51u_post
1911    o this is the post-merge tag of the ecco-branch
1912      (needs another clean checkout and re-testing)
1913    o various natl_box_adjoint configs and results
1914      but no input fields
1915    o obcs adjoint not yet merged!
1916    o adding ECCO global 1x1 and 2x2 degree configs
1917    o updated/extended some store directives for seaice
1918    o pkg/ecco now containes ecco-specific part of cost function
1919    o top level routines the_main_loop, forward_step
1920      supersede those in model/src/
1921      previous input data.cost now in data.ecco
1922      (new namelist ecco_cost_nml)
1923    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1924    
1925    checkpoint51t_post
1926    o this is the pre-merge tag of the ecco-branch
1927    
1928    checkpoint51s_post
1929    o cleanup: removed various obsolete #define-s
1930    o pkg/grdchk
1931      - renamed 'ph-grd 3' to 'grad-res'
1932      - merged from ecco-branch
1933        (remaining bug fixes for obcs gradient checks)
1934      - additional high-precision output for testreport
1935        (grep for 'precision_grdchk_result')
1936    
1937    checkpoint51r_post
1938    o cleaned up or removed CPP_OPTIONS.h files
1939    o updated results for some of the tests to reflect the new
1940      optfiles (-ieee: -O0 instead of -O3)
1941    
1942    checkpoint51q_post
1943    o cd_code:
1944      - moved cd_scheme.F -> cd_code_scheme.F
1945      - separate read_checkpoint from cd_code_ini_vars.F
1946      - separated cd_code part from write_checkpoint

1956    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1957    
1958    checkpoint51p_post
1959    o create initial cd_code package
1960      - WARNING: the initialization of fields within packages
1961        is broken because INI_FIELDS (where READ_CHECKPOINT is
1962        called) is called *before* PACKAGES_INIT_VARIABLES.
1963        This seems to be backwards since
1964        1) its important to initially zero the entire field including
1965           the "halo" region
1966        2) zeroing needs to be done *before* reading pickup info
1967           and the pickup call might or might not happen in any
1968           particular run
1969      - this needs an overhaul for R2
1970    o cleanup verification/*/code/GMREDI_OPTIONS.h

2005      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
2006      - subroutine FREEZE now limits only surface temperature
2007        (this means new output.txt for global_ocean.90x40x15,
2008         global_ocean.cs32x15, and global_with_exf)
2009    o added surface flux output variables to TIMEAVE_STATVARS

2179    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
2180    o AIM: use true log-P extrapolation for near surface temp (= as in
2181        F.Molteni paper) ; update aim.5l_cs output.
2182    o New variable in PARM03 for more flexible pickups
2183    o somewhat cleaned package initialisation sequence for
2184      ctrl/ cost/ ecco/ in packages_... routines

2212     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
2213       nearly a copy of kpp_transport_s
2214     - there is no analogue to SurfaceTendencyS, so I have to use
2215       gPtr(of the surface layer) instead
2216    o add a new platform SunFire+mpi (SunFire 15000) to genmake
2217    checkpoint50e_pre
2218    
2219    checkpoint50d_post
2220    o change kpp output from multiple-record state files to single-record state
2221      files analogous to write_state.F
2222    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
2223      analogous to the cg2d-related output.
2224    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
2225      so that writing to internal file fn (with length 512) fails.
2226    checkpoint50d_pre
2227    
2228    checkpoint50c_post
2229    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
2230    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
2231    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
2232    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
2233    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
2234    
2235    checkpoint50c_pre
2236    Merging from release1_p13:
2237    o bug fix for pkg/seaice dynamic solver
2238    o Added SEAICE_initialHEFF to pkg/seaice
2239    
2240    checkpoint50b_post
2241    o store u*,v* in gU,V instead of in guNm1,gvNm1
2242    o in order to put the momForcing out of the Adams-Bashforth:
2243      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
2244      to timestep.F
2245    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
2246    o re-generate output for highly sensitive test-exp:
2247       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
2248    
2249    checkpoint50b_pre
2250    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
2251    o corrected CPP option mismatch in exf_Bulk... functions for case
2252      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
2253    
2254    checkpoint50a_post
2255    o Bug fix for merging between c50 and KPP.
2256      ikey was passed from thermodynamics to kpp_calc via
2257      common block rather than being recomputed in kpp_calc,
2258      in contradiction with new key itdkey.
2259      New key ikppkey created, and tamc.h headers updated.
2260    
2261    checkpoint50
2262    - 2nd step of merge with ecco-branch:
2263      merge changes in ecco-branch back into main trunk
2264    - bug fix in find_alpha
2265    - more storing in gmredi_calc_tensor.F, kpp_routines.F
2266    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
2267    - merged some sliced AD support routines
2268    
2269    checkpoint49
2270    merged from ecco-branch:
2271    o exf:
2272      - Enable initialisation of forcing fields to constant
2273        (runtime) values.
2274      - in exf_getffields.F
2275        Reduce i-/j-loop to interior domain, discarding overlaps.
2276        That also fixes wrong TAF-key computations for key_1, key_2
2277        with bulf formulae.
2278      - exf_init.F modify #ifdef for exf_init_evap
2279      - exf_getffieldrec.F, ctrl_getrec.F
2280        The following INT-usages are not safe:
2281          fldsecs  = int(fldsecs/fldperiod)*fldperiod
2282          fldcount = int(fldsecs/fldperiod) + 1
2283        and were modified.
2284    o autodiff: checkpoint_lev...
2285      - updated storing for bulk formulae (some arrays were missing)
2286      - added state for seaice package
2287      - synchronized with main branch
2288    o DIVA:
2289      Modif.s in
2290      - the_main_loop.F
2291      - the_model_main.F
2292      and added cost_final_restore.F cost_final_store.F
2293      o With these changes, it is possible to fully separate
2294        the first forward run to compute the cost function (mdthe_main_loop)
2295        and adjoint runs over individual DIVA intervals (adthe_main_loop)
2296        into separate model executions.
2297        This enables better tuning of DIVA to given queue sizes.
2298      o Loss of cost function value in consecutive DIVA runs is
2299        fixed by storing to 'costfinal' file.
2300      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
2301        beginning/end of adjoint integration is accounted for.
2302      The current changes apply to TAF-1.4.26.
2303      TAF has one remaining bug, requiring one manual change
2304      (see MITgcm manual).
2305    o cal: synchronized between MAIN and ecco-branch
2306    
2307    checkpoint48i_post
2308    o Changes to restore differentiability of code w.r.t. previous tag
2309      (mostly adding new routines to make list and replacing
2310      pressure by totPhiHyd).
2311    o Updated and merged grdchk package
2312      - has both ADM and TLM checks
2313      - works for single- and multi-proc.
2314      - output cleaned
2315      - worked successfully for parallel DIVA
2316    o genmake:
2317      - Adding -platform=SP4
2318      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
2319    o Modif. for DIVA:
2320      ctrl_unpack should not be called in intermediate DIVA interval.
2321      (similar thing would apply for active files such as
2322      tbar, sbar, psbar, which should not be reinitialised;
2323      only relevant for ecco-branch)
2324    
2325    checkpoint48h_post
2326    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
2327    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
2328    o Added SEAICE_initialHEFF to pkg/seaice
2329    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
2330    
2331    checkpoint48g_post
2332    --- EOS:
2333    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
2334      store total Potential in totPhyHyd for diagnostics & EOS.
2335    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
2336    --- Pressure/geopotential gradient:
2337    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
2338    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
2339      ( changes results of global_ocean_pressure )
2340    o NLFS + z-coord.: add eta*Rho' contribution.
2341    o accurate phiHyd when using interface-W at the middle between 2 centers
2342     ( changes results of ideal_2D_oce )
2343    o includes r* 2nd term in potential gradient.
2344    
2345    checkpoint48f_post
2346    Merging from release1_p12:
2347    o Modifications for using pkg/exf with pkg/seaice
2348      - improved description of the various forcing configurations
2349      - added basic radiation bulk formulae to pkg/exf
2350      - units/sign fix for evap computation in exf_getffields.F
2351      - updated verification/global_with_exf/results/output.txt
2352    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
2353      (SBO) core products, including oceanic mass, center-of-mass,
2354      angular, and bottom pressure (see pkg/sbo/README.sbo).
2355    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
2356      to avoid negative values in shallow regions.
2357      - updated verification/natl_box/results/output.txt
2358      - updated verification/lab_sea/results/output.txt
2359    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
2360    o Added useSingleCpuIO option (see PARAMS.h).
2361    o Updated useSingleCpuIO option in mdsio_writefield.F to
2362      work with multi-field files, e.g., for single-file pickup.
2363    o pkg/seaice:
2364      - bug fix in growth.F: QNET for no shortwave case
2365      - added HeffFile for specifying initial sea-ice thickness
2366      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
2367    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
2368      kpp_transport_t.F, forward_step.F, and the_main_loop.F
2369    o pkg/seaice:
2370      - adjoint-friendly modifications
2371      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
2372    
2373    checkpoint48e_post
2374    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
2375    o dynamics: change definition of computational domain & adapt mom_fluxform
2376      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
2377    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
2378        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
2379        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
2380        global_ocean.90x40x15 global_with_exf global_ocean_pressure
2381        inverted_barometer solid-body.cs-32x32x1
2382      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
2383    
2384    checkpoint48d_post
2385    o in preparation for r*:
2386     a) use pre-computed gradient of hydrostatic potential:
2387        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
2388     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
2389        => affects results of glob_oce_pressure (different truncation error)  
2390      update output.txt of ideal_2D_oce & global_ocean_pressure
2391    
2392    checkpoint48d_pre
2393    o in preparation for r*:
2394      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
2395      pass the 2 comp. of the grad. as arguments to momentum S/R.
2396      but for the moment, only used if it does not change the results.
2397    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
2398    
2399    checkpoint48c_post
2400    Modifications in treatment of initial flux forcing controls
2401    to avoid extra storing of flux fields.
2402    
2403    checkpoint48c_pre
2404    o Added tidal_basin_2d experiment (currently 1D!)
2405    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
2406    
2407    checkpoint48b_post
2408    o r* coordinate added in #ifdef NONLIN_FRSURF block.
2409     (modification to pressure gradient not yet implemented)
2410    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
2411      (for U & V) that are used for vertical advection of momentum.
2412    
2413    checkpoint48a_post
2414    o In preparation for r*, use temp. array to compute vertical transport
2415       in flux-form momentum pkg. => change results of few test-exp.
2416      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
2417                        lab_sea, natl_box & plume_on_slope
2418    
2419    checkpoint48
2420    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
2421    
2422    checkpoint47j_post
2423    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
2424    o moved adexch from forward_step to addummy_in_stepping
2425    o added exch in ctrl_map_...
2426    o aveFreq.=0. at end of cost_final to avoid overwrite in
2427      reverse checkpointing loop
2428    o Yet more changes in gmredi:
2429      * adgmredi_calc_tensor
2430        avoiding all recomputation of gmredi_slope_limit
2431      * adgmredi_x/y/rtransport
2432        added flag for excessive storing to avoid recomp. of
2433        u/v/rtans, dTdx/y/z
2434        -> this is not really necessary and very memory-consuming
2435      * adgmredi_slope_psi:
2436        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
2437      * gmredi_slope_limit
2438        re-activated full calculation of taperfct for case 'ac02'
2439    o updating verification/ adjoints of carbon, global_ocean.90x40x15
2440    
2441    checkpoint47i_post
2442    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
2443    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
2444      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
2445    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
2446    o gmredi: fix few bugs.
2447    
2448    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
2449    This will be a good checkpoint to plug into the ecco-branch.
2450    o few modif.'s to get latest version adjointed
2451      (mainly kick out code in ini_linear_phisurf)
2452    o modif's to run adjoint with exactConserv
2453    o case GM_BOLUS_ADVEC should be cleaned
2454      S/R gmredi_slope_psi should be cleaned
2455    o verification/carbon now has exactConserv=.TRUE.
2456    
2457    checkpoint47g_post
2458    o time-average AIM output: becomes independent from statvars time-average
2459      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
2460    o After TAF bug fix:
2461      Tested adjoint of gmredi package.
2462      Tests were done with checkpoint47 rather than with latest
2463      checkpoint47f_post since the latter is broken for the adjoint
2464      verification/carbon/ contains both ADM and TLM gradient checks.
2465    Here they are, before they get changed/lost/stolen.
2466    Mostly modif.'s to fix numerical sensitivities.
2467    Gradient checks OK for
2468    - GM_taper_scheme:
2469      * clipping
2470      * ac02
2471      * linear
2472      * glw91
2473      * dm95
2474      * ldd97
2475    - GMREDI_OPTIONS:
2476      * GM_VISBECK_VARIABLE_K
2477      * GM_NON_UNITY_DIAGONAL
2478      * GM_EXTRA_DIAGONAL
2479      * GM_BOLUS_ADVEC
2480    in conjunction with data.gmredi parameters to be checked in
2481    in a few minutes under verification/carbon/code/
2482    
2483    checkpoint47f_post
2484    Merging from release1_p10:
2485    o modifications for using pkg/exf with pkg/seaice
2486      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
2487        and SEAICE_EXTERNAL_FLUXES
2488      - pkg/exf CPP options EXF_READ_EVAP and
2489        EXF_NO_BULK_COMPUTATIONS
2490      - usage examples are Experiments 8 and 9 in
2491        verification/lab_sea/README
2492      - verification/lab_sea default experiment now uses
2493        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
2494    
2495    checkpoint47e_post
2496    o created a tag prior to creating a branch
2497    
2498    checkpoint47d_post
2499    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
2500      at the bottom boundary had an erroneous half slip boundary condition
2501    o added bottom drag and no slip boundary condition capabilities to
2502      oceanic pressure coordinates code
2503    o added new verification experiment global_ocean_pressure, this experiment is
2504      also described in the tutorial section of the manual
2505    checkpoint47d_pre
2506    
2507    checkpoint47c_post
2508    o Added a verification experiment for a global cubed-sphere ocean run
2509      -  verification/global_ocean.cubed32x32x30
2510      -  uses pkg/therm_seaice and pkg/bulk_forcing
2511    
2512    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
2513    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
2514      when using P-coordinate; only implemented for atmospheric config.
2515    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
2516      NOTES: requires option NONLIN_FRSURF to be "#define".
2517    o update advect_xz/results/output.txt (left from checkpoint44g_post)
2518    
2519    checkpoint47b_post
2520    Merging from release1_p9:
2521    o pkg/seaice
2522      - removed GOTO's and added taf directives
2523      - double precision constants to reduce the g77 (Linux)
2524        to F77 (SGI) differences reported in release1_p8
2525    o tools/genmake
2526      - added SGI options
2527    o verification/testscript
2528      - updated to that of checkpoint47a_post
2529    o verification/global_ocean.90x40x15/input/eedata
2530      - modified for SGI f77 compatibility
2531    o verification/lab_sea
2532      - added description of sea-ice model
2533      - added missing matlab routines
2534      - added test of thermodynamics parallelization
2535    
2536    checkpoint47a_post
2537    o new pkg: aim_v23
2538     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
2539       for now, keep the same surface forcing as before.
2540     - Part-Cell implemented into AIM; check that Heat & Water are conserved
2541     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
2542     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
2543    o add diagnostic of surface correction term in monitor output
2544    
2545    o bulk_force and therm_seaice
2546    - Two packages:  bulk_force (Bulk forcing)
2547      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
2548    - Earlier integration from Stephaine Dutkiewicz
2549      and Patrick Heimbach.
2550    - Two ifdef statements for compile time,
2551       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
2552    
2553    checkpoint47
2554    differentiable version of checkpoint46n_post
2555    o bug fix in quasihydrostaticterms
2556    o * "clean" adjoint code (in terms of extensive recomputations)
2557        can now be obtained for all GMREDI options (i.e. for
2558        - GM_VISBECK_VARIABLE_K
2559        - GM_NON_UNITY_DIAGONAL
2560        - GM_EXTRA_DIAGONAL
2561        - GM_BOLUS_ADVEC )
2562      * However, wrong gradient check problem remains unsolved.
2563      * New CPP options have been introduced for different
2564        tapering schemes
2565    o external_fields_load now part of differentiation list
2566    o pressure needs multiple storing;
2567      would be nice to have store_pressure at beginning or
2568      end of forward_step, e.g. by having phiHyd global (5-dim.)
2569      (NB: pressure is needed for certain cases in find_rho,
2570      which is also invoked through convective_adjustment).
2571    o recomputations in find_rho for cases
2572     'JMD95'/'UNESCO' or 'MDJWF' are OK.
2573    o #define ATMOSPHERIC_LOADING should be differentiable
2574    o ini_forcing shifted to begining of initialise_varia
2575    o Incorporating QNVS line search routines into MITgcm
2576      (this is separate code, and therefore not under pkg)
2577      lsopt/, optim/
2578    o Updated verification/carbon/
2579      - #define GM_VISBECK_VARIABLE_K
2580      - GM_taper_scheme    = 'ldd97'    
2581    
2582    checkpoint46n_post
2583    Merging from release1_p8:
2584    o verification/natl_box:
2585      updating new external_fields_load routine
2586    o New package: pkg/seaice
2587      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
2588      The sea-ice code is based on Hibler (1979-1980).
2589      Two sea-ice dynamic solvers, ADI and LSR, are included.
2590      In addition to computing prognostic sea-ice variables and diagnosing
2591      the forcing/external data fields that drive the ocean model,
2592      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
2593      The implied surface heat flux is then stored in variable
2594      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
2595      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
2596      non-local transport term.  Because this call precedes model
2597      thermodynamics, temperature under sea-ice may not be "exactly" at
2598      the freezing point by the time theta is dumped or time-averaged.
2599      N.B.: fairly large differences in accuracy occur across
2600            different platforms/compilers; comparison between
2601            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
2602            generated output gives:

2610    o GAD:
2611      - generated new common blocks to account for call of
2612        same gad routines with differing traceridentities
2613        (needed to modify tracerIdentity indices in GAD.h)
2614      - generated separate common blocks for case useCubedSphereExchange
2615        (Department of Futurology)
2616      - parameter lists to gmredi_?transport: added tracerIdentity
2617      - added new key indices to tamc.h
2618    o external_fields_load:
2619      - added this routine to TAF list
2620      - needed to make some common blocks global and additional storing
2621        along the same lines as exf package (checkpoint_lev?_directives.h)
2622    o exf:
2623      updated external forcing package
2624      - bug fixes carried over from ecco-branch
2625        (missing OBCS_OPTIONS.h in two routines)
2626      - enable easy to use "no forcing".
2627      - added exf I/O for atmospheric loading
2628      - added exf I/O for runoff data
2629      - transfered scaling between exf <-> MITgcm to exf namelist
2630    o Adding new verification experiment global_with_exf.
2631      This verification experiment is almost identical to the
2632      global_ocean.90x40x15 experiment, except that it uses
2633      the exf (and cal) package instead of the
2634      external_fields_load routine (cf README file).
2635    
2636    checkpoint46m_post
2637    o modified testscript to return -- when there are no lines of "%MON" output
2638    o added new flag "quasiHydrostatic" for QH mode
2639      and new routine quasihydrostaticterms()
2640    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
2641      New routine: mom_u_coriolis_nh()
2642    o fixed sign of non-hydrostatic metric terms in u and v equations.
2643      Depend on correct sign of gravitySign.
2644    o added work.pc* to .cvsignore in aim directories using ifc
2645    o introduced flag for controllin non-hydrostatic metric terms
2646    o removed gravitySign from PARM04
2647    o switched to g77/ifc from pgf77 in aim experiments
2648    
2649    checkpoint46l_post
2650    o made convective adjustment work with pressure coordinates:
2651     - changed the direction of k-loop in convective_adjustment.F for the
2652       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
2653     - adjusted the reference pressure k-index in convective_adjustment.F
2654     - adjusted the convection condition in convect.F (in analogy to
2655       calc_ivdc.F)
2656     - convective_adjustment no longer computes anything on the halos
2657     - removed the warnings about negative salinity from find_rho.F and
2658       find_alpha.F; instead the new routine look_for_neg_salinity, called
2659       at the beginning of find_rho, find_alpha, and find_beta, does a
2660       check of the entire slice, if CPP-option
2661       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
2662    checkpoint46l_pre
2663    
2664    checkpoint46k_post
2665    o fixed the verification/global_ocean.90x40x15 experiment:
2666     - new bathymetry (the world according to A., JMC, and M.)
2667     - new initial fields and forcing fields (*.bin files)
2668     - new POLY3.COEFFS (for the next release one should switch to a full
2669       equation of state: JMD95P or MDJWF)
2670     - fixed several errors and redundancies in the data file
2671     - experiment uses looped cells
2672     - added matlab directory with diagnostic scripts for plotting of output
2673    
2674    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
2675     - read AIM physics parameters from a file (data.aimphys)
2676     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
2677    
2678    checkpoint46j_post
2679    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
2680    o move wVel computation at the end of the time step, in S/R integr_continuity
2681    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
2682    o update timeave pkg for wVel diagnostic.
2683    checkpoint46j_pre
2684    
2685    checkpoint46i_post
2686    o Clean up AIM package (and keep the results unchanged):
2687      include CPP_OPTION and use IMPLICT NONE in all routines ;
2688      declare all the variables _RL ; use _d 0 for all numerical constants.
2689      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
2690    
2691    checkpoint46h_post
2692    o cleaned up the use of rhoNil and rhoConst.
2693      - rhoNil should only appear in the LINEAR equation of state, everywhere
2694        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
2695        and the dynamical equations are all divided by rhoConst
2696    o introduced new parameter rhoConstFresh, a reference density of fresh
2697      water, to remove the fresh water flux's dependence on rhoNil. The default
2698      value is 999.8 kg/m^3
2699    o cleanup up external_forcing.F and external_forcing_surf.F
2700      - can now be used by both OCEANIC and OCEANICP
2701    checkpoint46h_pre
2702    
2703     Added code to convert surface volume flux (fresh water) into
2704     a mass flux when using P coordinates in the ocean (OCEANICP).
2705     Note: It assumes you have set rho0=rhoConst=density of fresh water.
2706    
2707    checkpoint46g_post
2708    o Include a new diagnostic variable phiHydLow for the ocean model
2709      - in z-coordinates, it is the bottom pressure anomaly
2710      - in p-coordinates, it is the sea surface elevation
2711      - in both cases, these variable have global drift, reflecting the mass
2712        drift in z-coordinates and the volume drift in p-coordinates
2713      - included time averaging for phiHydLow, be aware of the drift!
2714    o depth-dependent computation of Bo_surf for pressure coordinates
2715      in the ocean (buoyancyRelation='OCEANICP')
2716      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
2717        Theta, Salinity, and Pressure in the parameter list. This routine is
2718        presently contained in find_rho.F. This routine does not give the
2719        correct density for 'POLY3', which would be a z-dependent reference
2720        density.
2721    o cleaned up find_rho
2722      - removed obsolete 'eqn' from the parameter list.
2723    o added two new verification experiments: gop and goz
2724      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
2725    checkpoint46g_pre
2726    
2727    checkpoint46f_post
2728    o Enable tangent linear (forward mode) gradient checks:
2729      - extended active file handling to g_... files
2730      - added TANGENT_SIMULATION to theSimulationMode
2731      - extended grdchk package accordingly
2732    o added tangent linear setup in verification/carbon/code_ftl
2733    o added adjoint setup in verification/front_relax/code_ad
2734    
2735    checkpoint46e_post
2736    o Added new equation of state -> MDJWF
2737      - EOS of McDougall et al., 2002, JAOT, submitted
2738      - caveat: the equation of state is only valid for a smaller (more
2739        realistic?) range of values than JMD95P/Z and UNESCO
2740      - added masks to the calculation of pressure in store_pressure
2741      - added more check values for density in check_eos (ini_eos.F), some of
2742        the old check values are out of the range of the MDJWF-eos, so don't
2743        expect perfect matches for those
2744    checkpoint46e_pre
2745    
2746    checkpoint46d_post
2747    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
2748      'OCEANICP', also initialised field pressure correctly in ini_eos in the
2749      case of pressure coordinates. eosType='JMD95Z' in
2750      combination with buoyancyRelation='OCEANICP' now causes an error.
2751    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2752      in find_alpha/beta.
2753    checkpoint46d_pre
2754    
2755    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
2756      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
2757    
2758    checkpoint46c_post
2759    o Changes necessary for ocean in p-coordinates
2760     -  Added new buoyancy relation = 'OCEANICP'
2761     -  Added new parameters = gravitySign (this used to be contained inside
2762        the factor dRdZ which I added when we first switched to R coordinates).
2763     X GM/Redi is not compatible (yet)
2764     X bottom drag and no-slip need to be debugged.
2765    checkpoint46c_pre
2766    
2767    checkpoint46b_post
2768    o Added new equation of state -> JMD95Z and JMD95P
2769      - EOS of Jackett and McDougall, 1995, JAOT
2770      - moved all EOS parameters into EOS.h
2771      - new routines ini_eos.F, store_pressure.F
2772    o Added UNESCO EOS, but not recommended because it requires
2773      in-situ temperature (see JMD95)
2774    o Modified formatting for knudsen2.f in utils/knudsen2 and added
2775      unesco.f to be used with POLY3
2776    checkpoint46b_pre
2777    
2778    checkpoint46a_post
2779    o Added (atmospheric) pressure loading
2780      - new field in FFIELDS.h, etc...
2781      - new cpp flag ATMOSPHERIC_LOADING
2782    o Changed hFacC to _hFacC in calc_phi_hyd.F
2783    o Added SHORTWAVE_HEATING to some files for consistency
2784    checkpoint46a_pre
2785    
2786    checkpoint46
2787    further merges from release1_p5
2788    o new ctrl package
2789      - adopted from ECCO environment to enable optimization
2790      - added Eliassen Palm fluxes to controls
2791    o added Eliassen Palm flux controls to gradient check package
2792    o cost package
2793      - Compatible with new ctrl package
2794      - added Eliassen Palm cost hooks
2795      - modif's of existing cost functions
2796    o Adjoint-related bug fixes in kpp:
2797      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
2798      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
2799    o autodiff package
2800      - flow directives:
2801        + new for S/R do_the_model_io
2802        + enhanced for S/R checkpoint
2803        + new gmredi.flow
2804      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
2805        disable adcommon.h/g_common.h by default.
2806      - fixed problem for adjoint of global_max
2807    o modified verification/carbon/
2808    o New setup for adjoint of global_ocean
2809    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
2810    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
2811    o incorporated hooks for sponge layer code (external_forcing.F)
2812    
2813    checkpoint45d_post
2814    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
2815    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
2816      (affects plume_on_slope "cg2d" output)
2817    o add new parameter deltaTfreesurf for free-surface time stepping
2818    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
2819    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
2820    o change phiMin in exp1 (to agree with documentation)
2821    o add new flags:
2822     - T,S forcing inside/outside Adams-Bashforth
2823     - turn off temp,salt advection and/or forcing
2824     - for each tracer, define internal flag for multiDimAdvection & A-B
2825    o monitor: change definition of KE to check conservation of Energy
2826    
2827    checkpoint45c_post
2828    o Removed f90 comments ("!")
2829    o Modified initialisations to enable exf package for MITgcm
2830      (without invoking ECCO_PACKAGE).
2831    o modifications to gradient check package (Martin Losch)
2832      - enable centered differences
2833      - modified format of standard output
2834    
2835    checkpoint45b_post
2836    o cleaned exchange calls in cg2d
2837    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
2838    o included CPP option SINGLE_LAYER_MODE in thermodynamics
2839      to configure barotropic setup (Martin Losch)
2840    o moved some initialisations within bi,bj loop in dynamics
2841      (TAF flow dependency)
2842    o in initialise_varia, moved call packages_init_variables
2843      before convective_adjustment_init
2844      (corresponding adjustment of TAF tape initialisation).
2845    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
2846    
2847    checkpoint45a_post
2848    o compute Rho over the whole domain (extend iMin,jMin indices)
2849    o specific exchange for X-slice domain (case Ny=1)
2850    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
2851    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
2852    
2853    checkpoint44h_post = checkpoint45
2854    o Fix to restore differentiability:
2855      place at which packages_init_variables is called in
2856      initialise_varia is crucial for reverse control flow.
2857    o modifications in GMRedi to enable stable adjoint
2858      (corresponding modif's in thermodynamics, dynamics)
2859    o added missing hook for sponge layer code in external_forcing
2860    o modified test cost functions
2861    o storing in gad_advection (plus removal of write(0,*)!
2862    o missing headers TR1.h added in convective_adjustment routines

2864      (conflict on some platforms, e.g. IBM SP3)
2865    o modified carbon verif.
2866    
2867    checkpoint44h_pre
2868    o vertical grid option: allow to put the Interface at the middle between
2869      2 cell-centers ; replace delZ in pkg/kpp by drF.
2870    o GM Advective form: Tracers are advected using the residual transport (=
2871      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
2872    
2873    checkpoint44g_post
2874    o fix surface correction term in multiDimAdvection (affects plume_on_slope
2875      results) ; ifdef missing in thermodynamics.F
2876    
2877    checkpoint44f_pre,checkpoint44f_post
2878    o added PTRACERS package
2879      This allows an arbitrary number of passive tracers to be integrated
2880      forward simultaneously with the dynamicaly model.
2881      + Implemented so far:
2882        - basic forward algorithm (time-stepping, advection, diffusion, convection)
2883        - I/O and checkpointing
2884        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
2885      + Not implemented so far:
2886        - KPP
2887        - OBCS
2888      + No specific example supplied (yet) but global_ocean.90x40x15 has the
2889        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
2890        line in data.pkg.
2891      + This package is disabled by default since it increases storage.
2892    
2893    
2894    o testscript: added -cleanup option
2895    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
2896                 b) enable to filter 2D fields.
2897    
2898    checkpoint44e_pre,post
2899    o re-wrote convective adjustment to use pre-calculated weights
2900      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
2901      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
2902      Original calls to convect() still in place.
2903    
2904    chkpt44d_pre,post
2905    o added missing EXCLUDE_MONITOR flags
2906    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
2907      (incompatible typ in MIN/MAX expressions caused problems
2908      on IBM SP3)
2909    o in genmake added variable MAKEDEPEND
2910      plus resetting for case SunOS
2911    o added timer_stats.c routine for IBM SP3
2912    o removed variables in dynamics
2913    !!! I forgot to create tag chkpt44d_pre !!!
2914    !!! But chkpt44d_pre = chkpt44c_post    !!!
2915    
2916    o real fresh water flux implemented with non-linear free-surface.
2917    
2918    chkpt44c_pre,post
2919    o few fix (mask in shap_s2, EmPmR in external_field_load,
2920      USE_NATURAL_BCS in solve_for_P);
2921    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
2922    
2923    checkpoint44b_pre/_post

2932                   added directive for divided adjoint in the_main_loop
2933      - pkg/mdsio: added mdsio_gl_slice
2934

2956    o New store directives for multi-dim. advection schemes
2957      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
2958      * new common block and key passkey

2960    o Modified store directives for split of dynamics/thermodynamics
2961      for the case ALLOW_KPP
2962    o Cleaned argument list for timestep_tracer.F
2963    
2964    checkpoint41
2965    o re-formatted/added comments in prologues of key subroutines
2966      to work with protex
2967    
2968    checkpoint40
2969    o moved calc_gs, calc_gt and calc_tr1 back to model/src
2970    o added FLT (floats) package from Arne along with demo. experiment
2971    o re-arranged Adams-Bashforth scheme for tracers to allow easier

2986      
2987    checkpoint40pre8
2988    o new package rw/
2989      Added method for dumping intermediate local arrays:
2990      mdsio_writetile - same as mdsio_writefield except works from inside
2991                        bi,bj loop
2992      mdsio_writelocal - same as mdsio_writetile except works for local
2993                         arrays
2994      write_local_r? - higher-level wrapper for mdsio_writelocal
2995      Controlled by diagFreq. Defaults to zero (ie. no dumps)
2996      Example given at end of mom_vecinv.F that dumps some local arrays.
2997    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
2998      control flux-form versus vector invariant code.
2999      Switch is runtime flag vectorInvariantMomentum (defaults to false)
3000      or genmake -DISABLE ...
3001    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
3002      (additional storing is now needed for case vecinv;
3003      currently nothing implemented to switch this storing off
3004      in case fluxform is used since no CPP flag available).
3005    
3006    checkpoint40pre7
3007    o bug fix in dynamics.F
3008      calc_viscosity called before k=1,Nr loop.
3009    o added some #ifdef's ALLOW_PASSIVE_TRACER
3010    o cleaned initialisations in ctrl_map_ini
3011      related to TAF
3012    
3013    checkpoint40pre6
3014    o split dynamics into thermodynamics & dynamics
3015    o corresponding split of calc_diffusivity into
3016      calc_diffusivity, calc_viscosity
3017      (kpp_calc_diff, kpp_calc_visc).
3018    o Added diffkr, kapgm to control variables
3019    o bug fix in gmredi_slope_limit for ldd97
3020    
3021    checkpoint40pre5
3022    o proper initialization of Adams-Bashforth time stepping
3023      + uses forward step for very first step of model (iter=0)
3024    o re-generated *all* output since almost all output is modified by this
3025      change (sorry but we've been putting this one off for about 2 years)
3026      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
3027        *not* regenerated since they are already out of date and I don't
3028        want to create the impression that they are suddenly working.
3029    o removed KAP stuff for DEC's
3030    o modified/added many .cvsignore files in */code and */input
3031    o added new expt "solid-body.cs-32x32x1"
3032      + this uses an alternative form of ini_curvilinear_grid.F which
3033        is not necessarily any better than the current one...
3034    
3035    checkpoint40pre4
3036    o added re-initialisations of utrans,vtrans,rtrans in
3037      calc_common_factors which are crucial for TAF.
3038    o extended iMin,jMin range for calc_common_factors,
3039      calc_diffusivity
3040    o added option ALLOW_PASSIVE_TRACER
3041    o a few minor updates and fixes
3042    
3043    checkpoint40pre3
3044    o created calc_gtr1.F for gad package
3045    o split the_main_loop and re-introduced forward_step
3046    o some recomputations of nIter0 for TAMC
3047    
3048    checkpoint40pre2
3049    o Updated to latest branch of AJA, JMC
3050    o Added gradient check package
3051    o Added routines for passive tracer handling
3052    o Added carbon sequestration sensitivity experiment
3053    
3054    checkpoint39
3055     o Modifications and fixes to support TAMC
3056       (mainly missing or wrong directives)
3057     o Corrected common blocks when fooling TAMC to produce adjoint I/O
3058       in addummy_in_stepping
3059     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
3060     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
3061     o Included following packages:
3062       cal: calendar
3063       exf: external forcing
3064       ecco: essential routines to control use of cal, exf
3065             (NB: this is not the full ECCO environment)
3066     o disabled some packages by default in genmake
3067    
3068  checkpoint38  checkpoint38
3069   o see notes_c37_adj.txt   o see notes_c37_adj.txt
3070   o corrected wrong layer index in external_forcing_t   o corrected wrong layer index in external_forcing_t
