5      ==============================      ==============================
6    
7    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
8      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
9    o pkg/seaice: a first HSALT time stepping equation has been checked in
10    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
11      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
12      without requiring DO-IF statements
13    o pkg/thsice:
14      use continuous power-law function for partition of energy between lateral
15      melting/freezing and thinning/thickening ; old code using step function
16      still available with #undef THSICE_FRACEN_POWERLAW
17      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
18    o testreport: change AD testing : check against results/output_adm.txt
19      using same scripts as for forward test.
20    
21    checkpoint59g
22    o adjoint testing: in preparation for changing testreport:
23      - output format: cost and grad written on separated lines
24      - ad output results in directory "results" (instead of "results_ad")
25    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
26    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
27    o pkg/ecco: allow user defined cost function contributions
28    o testreport:
29      Allow to choose (per experiment) the list of tested output variables
30       and the main variable (used to issue a pass/FAIL ) ;
31      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
32      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
33      Also modify printing of summary:
34       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
35       b) echo the list of tested variables in the individual summary.txt of
36          each experiment.
37    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
38      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
39      (but still depend on the tile decompostion of the domain).
40    o pkg/seaice: change a discretization detail to make the B-grid code
41      "more symmetric". This change is likely to remove all "ridges/leads" that
42      where quasi-aligned with the grid in B-grid solutions. It may also be
43      the solution to the stress coupling issues with the B-grid.
44    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
45      remove .cvsignore from input dir. (since testreport no longer run here).
46    o pkg/thsice:
47     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
48     - fix reshaping of sea-ice just after advection:
49       melt all the ice only if ice-volume is too small.
50     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
51       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
52     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
53    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
54      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
55    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
56      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
57      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
58      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
59      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
60      -> update output.txt
61    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
62     this affects truncation error: -> update output.txt of exp:
63      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
64      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
65    
66    checkpoint59f
67    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
68    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
69      a bounded range (in forward mode)
70    o pkg/ecco, ctrl, autodiff and mom_common:
71     internal parameter controls, completements of implementations
72    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
73    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
74      (not seem any difference in testing results).
75    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
76       at face corners.
77    o pkg/generic_advdiff:
78     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
79      loop range indices for computing vertical advection tendency
80      and do the calculation in the interior only (no overlap) ;
81      for now, only implemented for SOM advection (to save CPU time).
82     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
83    o exch2 adjoint
84      First set of changes:
85      - add exch2 hand-written adjoint templates
86      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
87        This will require cleanup in pkg/autodiff/*.F
88        (changed routines currently kept separate in verif. code/)
89      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
90        that used to hide exch2 or cubed-sphere specific code
91        (commented via 'cph-exch2')
92    o pkg/seaice
93      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
94    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
95       output of global_ocean.cs32x15.thsice .
96    
97    checkpoint59e
98    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
99      for B-grid vector (not yet tested) and C-grid vector (<- only used
100      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
101    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
102      (#ifdef ALLOW_SALT_PLUME)
103    o gather_2d/scatter_2d: removed halo regions
104    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
105      scheme and the corresponding test case (under front_relax dir). For now,
106      only available with Skew-flux form and not yet tested in realistic set-up.
107      adjoint: store directives updated, but gradient checks deteriorated,
108      so maybe GM/Redi adjoint is now broken.
109    o seaice adjoint
110      * add AREA, HEFF, HSNOW as control variable
111        (should not change lab_sea results)
112      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
113    o pkg/seaice:
114      * added computation of saltFlux in seaice_growth;
115        For time being, sea ice salinity is assumed constant
116        contribution of snow flooding to freshening of sea ice is neglected.
117        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
118        defaults to 0.0 in order to maintain backward compatibility.
119        Typical values for SEAICE_salinity are 4 to 10 g/kg.
120      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
121      * added SEAICE_availHeatFrac, which specifies fraction of surface level
122        heat content used to melt or grow ice
123      * commented out cap of HICE: it helps keep ice thinner
124      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
125      * applied OBCS T/S mask to HEFFM sea ice mask
126    
127    checkpoint59d
128    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
129     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
130     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
131    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
132     and change default value of parameter "GM_Small_Number";
133     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
134       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
135       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
136    o pkg/ecco: cost function when applying pkg/smooth to controls
137    o pkg/ctrl: add forcingPrecond run time parameter
138    o pkg/seaice:
139     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
140     - fix bug in metric terms of u-equation in LSR solver (implicit part),
141       changes verification/lab_sea
142     - rearrange implicit part of u-equation in LSR solver to make it easier to
143       read, understand, and debug. This causes changes at the truncation level.
144     - fix (serious) bug in the boundary conditions (sign error in the implicit
145       part) of the LSR solver. Changes all LSR results.
146     - fixed problem with HSNOW initialization to avoid thick snow when AREA
147       is initilized with small values - does not change lab_sea results.
148     - added HsnowFile initialization capability
149    o pkg/smooth: addition to model/src and pkg/ctrl so allow
150     initialization of pkg/smooth and application to control vector
151    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
152    o dependencies: pkg/profiles requires pkg/cal
153    o pkg/profiles:
154     - added option ALLOW_PROFILES_GENERICGRID
155         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
156         that interpolation information (grid points and coefficients) is provided
157         within the netcdf input files.
158         -> sample matlab scripts can be found in MITgcm_contrib/gael
159         that allow you to prepare netcdf input files.
160     - also modified: cleaner include statements, cleaner error print statements,
161       cleaner stops when error, and more tests of the netcdf input files consistency.
162    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
163    o pkg/seaice:
164     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
165       requires a new routine: seaice_diagnostics_fill.F
166     - make sure that seaice does not move if not forced (pressure replacement
167       method, Hibler and Ip, 1995), changes results
168     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
169     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
170       It is turned off by default (=-1.), because it changes the results.
171     - make it possible to read AREA from a file, too.
172    
173    checkpoint59c
174    o add S/R and diagnostics for oceanic mixed-layer depth
175    o move GMRedi call after all vertical mixing schemes (including KPP)
176    o pkg/thsice:
177     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
178      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
179    o pkg/obcs:
180     - bug fix for balance code
181    o pkg/seaice:
182      - allow values of SEAICE_elasticParm > 1
183      - add new parameter SEAICE_evpTauRelax as an alternative
184        to SEAICE_elasticParm
185      - make lsr boundary conditions free slip (by default), changes result
186      - add code for no slip boundary conditions for lsr
187      - set minimum of zeta to zero (and not 4e8) (changes results)
188      - add a cap on AREA after advecting AREA if seaice_growth is not called
189    o change calculation of Visbeck K:
190      - no longer depend on tapering scheme; instead, compute slope (limited
191        by GM_maxSlope). this is equivalent to what was comuted before with
192        clipping or linear tappering.
193      - fix vertical averaging (wrong by 1/2 level)
194      - leave the old version (but will not be maintained) within
195        #ifdef OLD_VISBECK_CALC / #endif
196      - update output of exp. ideal_2D_oce
197    o change error catch in calc_r_star to improve vectorization
198    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
199      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
200    o adjoint:
201      Re-organized adjoint checkpointing according to Matt Mazloff
202      (but with modifs/completions/cleanups)
203      Storing is now bundled into large arrays to optimized I/O
204      (and second step in cleanup of the_main_loop)
205    
206    checkpoint59b
207    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
208      - export/import (between ocean & coupler) fields needed for ocean DIC.
209    o pkg/seaice:
210      - get rid of three more exchanges seaice_calc_viscosities (required
211        different loop boundaries in seaice_lsr and seaice_ocean_stress)
212      - bug fix in seaice_ocean_stress (update of lab_sea required)
213      - reduce loop boundaries to necessary minimum also in seaice_evp
214      - go back to the old way of computing deltaC/Z as the adjoint likes that
215        better
216    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
217      passive tracer to an Age Tracer) + update output.txt
218    o pkg/exf:
219      - implement A-grid / C-grid selection for wind-stress input files.
220      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
221      for now, in exf_bulk_largeyeager04.F only :
222      - change implementation for case where windspeed + 2. components wind-stress
223        are read-in. AND use rhoConstFresh to convert evap.
224    o pkg/seaice:
225      - use correct EXCH_UV for wind-forcing (on A-grid).
226      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
227        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
228    o pkg/exf:
229      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
230      EXF_INTERPOLATION:
231      - merge global_with_exf/code version of exf_interp_read.F
232        to the main code ;
233      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
234        reading the file ; Important: This options needs to be defined to recover
235        previous code.
236        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
237      - no longer loose real*8 precision along the way when using exf_iprec=64.
238    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
239      - change discretisation of evp-solver in order to avoid another exchange
240        (changes lab_sea) and clean up a little
241      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
242        help the adjoint (this also changes the results slightly)
243      - add a few "_d 0" where they had been missing in seaice_evp.F
244      - cleaning up: remove unused seaice_calc_rhs.F
245    o pkg/exf: some cleaning-up:
246      - change various "constants" into runtime parameters
247      - cleaned-up Large&Yeager04 routine which should eventually
248        replace exf_bulkformulae.F (changed names of S/R and CPP)
249        and merged various ALLOW_ATM_WIND options
250     only used with thsice pkg (in thsice_get_exf.F):
251      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
252        which are used when useStabilityFct_overIce=TRUE (= the default)
253      - change default values of ice & snow emissivity and scale downward LW
254        by ice & snow emissivity.
255    o pkg/thsice:
256     fix few little problems, in thsice_calc_thickn.F:
257      - growth vertically (and not laterally) if iceFrac == iceMaskMax
258      - melt only laterally if hIce < hThinIce (as the comments say)
259      and in thsice_extend.F:
260      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
261      - start to form ice as soon as the minimum ice-volume is reachable.
262     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
263      and cpl_aim+ocn
264    o pkg/kpp
265     - move computation of surface related input fields to KPP into a new
266       subroutine kpp_forcing_surf.F
267     - remove wrong (within bi,bj loops) EXCH calls.
268     - little cleaning (add argument myThid in last position, cvs header ...)
269     - for now, fix conservation problem by exchanging KPPviscAz (may not
270       be the best fix)
271    o pkg/seaice
272     - check for inconsistent evp parameter/cpp-flag combination
273     - remove leftover errIO flat for obsolete name list error handling
274    o OpenAD
275     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
276    
277    checkpoint59a
278    o pkg/seaice: some parameter clarifications and a little bit of clean up
279    o pkg/thsice: rename run-time parameters:
280       himin       -> hIceMin
281       himin0      -> hThinIce
282       hihig       -> hThickIce
283       i0          -> i0swFrac
284       transCoef   -> bMeltCoef
285       frac_energy -> fracMelting
286      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
287       with default values (for now) that do not change the results.
288      remove old version of thsice vars advection in pkg/seaice.
289    o in FFIELDS.h:
290      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
291      - make pLoad & sIceLoad always available (but still only used if
292         ATMOSPHERIC_LOADING is #define).
293    o pkg/kpp: replaced _KPP_RL with _RL
294    o bug fixes for vertical diffusivity computations when both KPP and
295        3D diffusivity arrays are used.
296    o pkg/seaice: fix bug in evp solver, while doing that
297      - change (improve?) discretization of stress computations for both
298        cgrid-lsr and evp solver
299      - add a new routine to compute strain rates
300      - the above changes lab_sea results
301      - add no slip conditions for evp solver (off by default), lsr-version
302        may follow
303      - fix exchange for shear at Z-points (does not change lab_sea)
304      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
305        (to force the user to pick a time step since there is not "safe" way
306        of choosing it)
307      - add principal stress diagnostics
308      - rearrange fields for evp a little to avoid having to call a: too many
309        exchanges and b: exchanges for stress trensor components which we do
310        not have.
311      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
312        of evp, complete rewrite for lsr case (latter is does not yet work
313        in all cases)
314    o pkg/kpp: add code to have mixing in shelf ice caverns
315      - add myThid to all kpp routines (long overdue)
316    
317    checkpoint59
318    o pkg/exf:
319      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
320        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
321      - move exf header files from lower_case.h to UPPER_CASE.h ;
322        add missing cvs Header & Name
323      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
324      - add namelist param. selectStressGridPosition, exf_monFreq
325      - retire many _CLIM routines, and remove data.exf_clim
326        + params moved to data.exf
327        + climsst, climsss now handled by exf_set_gen, i.e.
328          climss?period=0 refers to constant field,
329          climss?period=-12 to monthly forcing
330      - split up namelists in data.exf
331    o pkg/seaice:
332      - remove seaice_exch and seaice_exch_uv
333      - remove superfluous exchange of theta
334      - add myThid to seaice_budget_ocean/ice
335      - add new interface for atmospheric wind forcing (C-grid only)
336        + new routine
337        + two new field (taux, tauy for stress over ice)
338        + removed one global field (DAIRN) for C-grid case only
339    o pkg/thsise
340      - 2nd set of modifs for thsice adjoint in conjunction with exf
341    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
342    
343    checkpoint58y_post
344    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
345      vertical diffusivity, similar to that in MOM4; turned on using
346      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
347      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
348    o Added capability for 3D specification of background vertical diffusion
349      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
350      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
351      "data" file that contains the 3D vertical diffusivity coefficients.
352    o ice dynamics (pkg/seaice) with thsice thermodynamics:
353      - add code within pkg thsice to advect & diffuse sea-ice fields
354      similar to (and will replace) what has been added in  seaice_advdiff.F,
355      but: - conserving Mass, Heat & Salt.
356           - better when using non-linear advection scheme (not yet fully tested)
357           - can also be used in atmospheric set-up (for now, only the diffusion).

359    checkpoint58x_post
360    o IO option for global-file compact format:
361      - add options when generating topology (utils/exch2/matlab-topology-generator)
362      - add I/O capability (pkg/mdsio).
363      - adapt utils/matlab/rdmds.m to read this format.
364      for now long-line format not yet supported by pkg/mdsio (& exch2).
365    o shelfice: add a few diagnostics
366    
367    checkpoint58w_post
368    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
369      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
370      (and replace horiVertRatio in NH code).
371      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
372                         and tutorial_plume_on_slope (sensitive to truncation)
373    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
374      directly to drive seaice model (C-grid only)
375    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
376     - reintroduce computation of wind from stress,
377     - compute tau (in exf_bulkformulae.F) from windstress averaged to
378       mass points to avoid tau = 0
379     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
380    o rdmnc.m: make it work with "global" files created with gluemnc
381    o rdmnc.m : some improvements in dealing with singleton dimension
382      (tested on all testreport mnc output files).
383    o genmake2: disable pkg/profiles if netcdf test fails.
384    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
385    o move call to cal_readparms up to make calendar parameters/variable available
386      to all packages
387    
388    checkpoint58v_post
389    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
390      useDynP_inEos_Zc tested.
391    o pkg/exf: changes to properly interpolate/mask/scale initial fields
392    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
393      and portions thereof.  See read_cs.txt for description and examples.
394    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
395      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
396      following the great-circle arc between those 2 points.
397    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
398      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
399    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
400     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
401     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
402     - still needs work (not working with some options ; efficiency to improve)
403       and serious testing.
404     - use this scheme for temperature & salinity in 2 advection test exp.:
405       advect_xy & advect_xz, respectively.
406    
407    checkpoint58u_post
408    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
409    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
410    o testreport: add option "-skipdir" to skip some test.
411    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
412      momentum calculation.
413    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
414    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
415      remove checkpoint.F and the_correction_step.F (no longer used);
416      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
417    o add option (linFSConserveTr) to correct for tracer source/sink due to
418      Linear Free surface
419    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
420    o pkg/thsice: fix reading mnc-pickups
421    
422    checkpoint58t_post
423    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
424    o pkg/mdsio:
425     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
426       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
427       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
428     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
429     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
430       either MDS_READ_FIELD or MDS_WRITE_FIELD )
431     - new S/R (to replace MDSWRITEMETA), which allows to write more
432       informations (variable names, time ...) to meta files.
433     - modify rdmds.m to give back the meta file content.
434    o pkg/diagnostics: change vertical interpolation to be safer, and more
435       flexible (define p-levels to interpolate to in data.diagnostics);
436      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
437       diagnostic pointer.
438    o pkg/seaice: more cleaning up of seaice_growth, added many comments
439    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
440    o fix multi-category seaice:
441     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
442       SEAICE_MULTICATEGORY
443     - fix short wave heat flux
444    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
445       and allow to use EVP solver. Change forward lab_sea: test both EVP
446       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
447    o Initial check-in of lab_sea adjoint
448      (very similar to natl_box_adjoint/code_seaice)
449      * used C-grid and EVP solver
450      * used KPP, GM/Redi
451      * uses inAdExact=.TRUE.
452      * gradient checks fail for both ADM and TLM
453        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
454        f.d. gradients actually seem more problematic than ADM, TLM gradients;
455        issue is related to forward mismatch between g77 an ifort
456    o pkg/seaice: overhaul of thermodynamics
457     - growth.F and groatb.F are replaced by new routine seaice_growth.F
458     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
459     - move a few global fields out of SEAICE.h into seaice_growth.F and
460       make them 2D (FICE/QNETO/ ...)
461     - remove FO (it is the same as QNETO)
462     - introduce a few local fields to avoid modifying external fields such
463       as atemp, etc.
464    
465    checkpoint58s_post
466    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
467      changed exf_set_gen.F so that
468        genperiod=0 means input file is one time-constant field and
469        genperiod=-12 means input file contains 12 monthly means
470    o CG2D: use pre-computed solver main-diagonal (stored in common block);
471      this affects truncation error ; generate new output file for exp. which
472      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
473        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
474        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
475        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
476        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
477        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
478    o start implementation of deep-atmosphere and anelastic formulation
479    o verification: remove 2nd copy of input files and use script "prepare_run"
480      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
481    o mom_common/vecinv/fluxform: fix a few initialisation isssues
482    o profiles: fix for multithreaded case
483    
484    o diagnostics: rename few diags:
485      s/'PRESSURE'/'RCENTER '/g
486      s/'TICE    '/'oceFreez'/g
487      s/'TAUX    '/'oceTAUX '/g
488      s/'TAUY    '/'oceTAUY '/g
489      s/'SWFLUX  '/'oceQsw  '/g
490      s/DIFx/DFxE/g
491      s/DIFy/DFyE/g
492      and add few ocean-forcing diagnostics:
493      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
494    o modifications to pkg/seaice/growth.F and budget.F, which change results of
495      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
496      as actual snow thickness.  It now refers everywhere to effective snow
497      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
498    
499    checkpoint58r_post
500    o modifications to pkg/seaice/growth.F, which change results of
501      lab_sea experiment: fixes pertain to melting snow over open water, to
502      masking EVAP under sea ice, and to using the correct AREA variable for
503      computations of EVAP, PRECIP, HSNOW, and GHEFF
504    o add ability to read bathy, salt, and theta using MNC (off by def)
505    o add flooding algorithm and advection of HSNOW for pkg/seaice;
506      both are turned off by default and do no change any results
507    o seaice advection with pkg/thsice: a step toward the use of non-linear
508      advection scheme, but #ifdef or commented out for now (requires more EXCH).
509    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
510      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
511      in natl_box (affects results @ truncation level: update output.txt)
512    o multi-threading and IO:
513      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
514      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
515        (needed to work with SingleCpuIO): tested in all verif. exp.
516    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
517      affects the results (but none of the verification test uses this scheme).
518    o Adding some pkg/diagnostics capability to pkg/seaice
519      (will certainly be subject to changes)
520    o ctrl: adding new control variables:
521      lwflux, lwdown, evap, snowprecip, apressure, runoff
522    
523    checkpoint58q_post
524    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
525      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
526      high_res_cube configuration by 4% on Columbia.
527    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
528      add (in global_with_exf/code) a version of EXF_INTERP_READ without
529      dynamical allocation (seems to work in multi-threaded).
530    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
531      single CPU io) so that TAF does not have to see EESUPPORT.h
532    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
533    
534    checkpoint58p_post
535    o obcs: stop if obcs is used with useCDscheme = .true.
536    o shelfice:
537     - fix a sign error so that no slip at shelfice interface works
538     - remove stop for combination non-hydrostatic code and shelfice. That does
539       not mean, that the results are correct, but at least they are numerically
540       stable
541    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
542    o added adjoint exch routined for all exch*3d* routines
543      and updated flow directives
544    
545    checkpoint58o_post
546    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
547      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
548    o change controling S/R for writing pickup file (new S/R do_write_pickup)
549      and clean-up reading/writing of pickup files.
550    o fix local version of read/write pickup (NH part) in rotating_tank/code
551    o simplify EXCH interface:
552     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
553     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
554    o added the regrid package
555    o shelfice:
556     - add a simple boundary layer scheme to reduce noise
557     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
558    
559    checkpoint58n_post
560    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
561       local variable (not in common block).
562    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
563      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
564      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
565        to work with SingleCpuIO.
566    o add "_d 0" to real constant of pkg/cfc subroutines ;
567       update exp. cfc_exemple & tutorial_cfc_offline output files.
568    o multi-threading and IO:
569      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
570        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
571      - barrier before and after reading.
572      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
573      - avoid using MDS_WRITELOCAL for LAND pkg output.
574      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
575        common-block variables ; Allows multi-threading with master-thread IO.
576    o change default MAX_NO_THREADS from 32 to 4 ;
577      and stop cleanly when MAX_NO_THREADS is too small.
578    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
579    
580    checkpoint58m_post
581    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
582       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
583    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
584       keep global_ocean.90x40x15 (for AD testing) with former secondary test
585       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
586    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
587        add MITgcm_tutorials (= code + all the tutorials)
588    o ecco, option to compute cost for total ssh (mean+anom)
589    o consistent with addition of ptracer and ssh in pkg/profiles
590    o profiles: adding ptracer and ssh
591    o testreport: change multi-test output-file name
592      (from output.txt.{name} to output.{name}.txt)
593    o profiles: now ok for mutli-tiles case
594    o seaice: add 4 parameters for different advection schemes for area,
595      (effective) seaice thickness, enthalphy, and snow height. Their default
596      is the standard parameter SEAICEadvScheme
597    o calc_gw:
598     - add cosFacU in zonal viscous flux (harmonic.visc.).
599     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
600       of tutorial_plume_on_slope.
601    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
602    o calc_gw: true flux-form, account for horizontal grid spacing.
603      update rotating_tank results, but not plume_on_slope (affected at
604      truncation level, 11 digits).
605    
606    checkpoint58l_post
607    o calc_gw:
608     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
609     - remove side-drag for now (need to fix it); update plume_on_slope results.
610     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
611    o commit code to make SST/SSS weights spatially variable
612      (based on either variable in-situ or variable initial T/S weights)
613    o pkg/ecco:
614      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
615        now based on horizontally varying weights wthetaLev, wsaltLev
616      * cost_averagesflags now returns year indices in addition to day, month
617      * sflux balance is performed on annual basis
618        (sflxumm, sfluxmm2, bal_sfluxmm)
619      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
620        including separate counting and multipliers
621    o pkg/rbcs
622      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
623    
624    checkpoint58k_post
625    o testreport:
626     - always build in dir. "build" (if not there, mkdir build instead of building
627       & running in input)
628     - run in dir run (if it exists), in build otherwise.
629     - call prepare_run (if input/prepare_run exists)
630     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
631    o pkg/exf modifications to interpolation and rotation routines for more
632       reasonable treatment of North Pole singularity: for tracers North Pole
633       value is set to northernmost zonal-mean value, for zonal velocity it is
634       set to zero, and for meridional velocity it is set to northernmost value.
635    o pkg/exf/exf_check_range.F
636     - add tile index to diagnostics and move stop statement to the very
637       end of the routine.
638    o pkg/diagnostics: (diagnostics_main_init.F)
639      define title of isomorphic variables according to the current config.
640    o pkg/thsice with pkg/seaice dynamics:
641    - fix domain of computation (interior only, required for exf) and do exchanges
642    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
643    o towards a standard way of dealing with multi-threading in MONITOR
644      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
645    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
646       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
647    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
648    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
649    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
650       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
651    o tracer advection:
652     - clean-up and simplify calc_common_factors.F
653     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
654       advection subroutine (but still not used within DST advection S/R)
655    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
656    
657    checkpoint58j_post
658    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
659      from file (collects calls previously in FORWARD_STEP)
660    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
661    o adjoint store dir. adjusted accordingly
662    o genmake2
663      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
664    
665    checkpoint58i_post
666    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
667      on wind stress (SEAICEstressFactor defaults to 1.)
668    o Total number of Timers is finite (<=40): comment out 2 non-essential one
669      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
670    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
671      on CS-grid: no longer loosing mass.
672    o exf & curvilinear-grid: no longer modify longitude xC & xG.
673    o pkg/ggl90: fix sloppy output and fix a bug
674    o pkg/seaice: added SEAICEuseEVPpickup parameter
675      - Set to false in order to start EVP solver with
676        non-EVP pickup files when using SEAICEuseEVP
677      - fix sign error in diffusion in seaice_calc_rhs
678    
679    checkpoint58h_post
680    * Modifications for bottom topography control
681      o replace hFacC by _hFacC at various places
682      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
683      o add non-self-adjoint cg2d_nsa
684      o update autodiff support routines
685      o re-initialise hfac after ctrl_depth_ini
686      o works for 5x5 box, doesnt work for global_ocean.90x40x15
687    * Adding verification for 5x5 box (4-layer) bottom topography control
688    
689    checkpoint58g_post
690    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
691       used for mean seasonal cycle, mean diurnal cycle); add an example
692       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
693    o pkg/ggl90:
694      - add parameter (minimum surface kinetic energy)
695      - fix bug (avoiding division by zero)
696    o couple pkg/thsice to pkg/seaice:
697      - modify advection in seaice to accomodate new scalar fields to be advected
698      - only muliDimAdection scheme work with seaice/thsice
699      - mapping of thsice-variables to seaice-variables, back and forth
700      - does not break the verification experiments, but does not give the
701        desired results either
702    o pkg/seaice
703      - make (default) second order advection a bit less confusing?
704    
705    checkpoint58f_post
706    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
707      to pkg/seaice):
708      - new routines thsice_map_exf and thsice_get_exf provide the interface
709      - add an additional formal parameter to thsice_solve4temp
710    o pkg/exf:
711      - add new fields wspeed, snowprecip (to be able to couple to thsice)
712      - correct Stefan-Boltzmann constant
713      - new parameter for longwave surface emittance
714      - separate some stuff from exf_bulkformulae into new routines  
715        exf_radiation, exf_wind
716      - add new parameters and constants: longwave emissivity for ocean, ice
717        and snow, evaporation parameters over ice
718      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
719        either wind from stress or stress from wind
720    o pkg/thSIce:
721    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
722    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
723       and THSICE_CALC_THICKN
724    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
725    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
726      to make debugging easier.
727    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
728    o pkg/bulk_force:
729      - clean-up comments and parameters ;
730      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
731    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
732      generate new output for test-experiment: aim.5l_cs.thSI
733    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
734      testreport accordingly
735    
736    checkpoint58e_post
737    o SEAICE_CGRID adjoint done
738    o R_STAR adjoint implemented.
739      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
740      * need to sort out init. of h0facc, etc.
741    o Make pkg/profile fully independent of ecco,cost, etc. stuff
742      to be able to use it in pure forward.
743    
744    checkpoint58d_post
745    o upgrade simple test-experiment to tutorial example:
746     step.1: duplicate the experiment and (step.2) will remove the old copy.
747      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
748      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
749      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
750      tutorial_global_oce_biogeo    <- copy of dic_example
751      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
752      tutorial_plume_on_slope       <- copy of plume_on_slope
753      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
754      tutorial_global_oce_optim     <- empty for now (David ?)
755      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
756     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
757    o correct a sign problem in cost_scat.F
758    o obcs and ptracers: fix boundary conditions for advections schemes
759      with larger stencil
760    o thsice adjoint: start
761    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
762      completeness
763    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
764      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
765    o ptracers adjoint:
766      * avoid extensive recomputatations
767      * fix missing re-init. of gptr (missed by TAF)
768    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
769      me to turn off the excessive output to STDOUT that this package produces
770    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
771      and add those terms in Vector-Invariant formulation.
772    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
773      if the control period (xx_hfluxperiod etc) is 0
774    o in profiles pkg, clean routines and fix details
775    o in ecco pkg, reading ssh data:
776      fix problem in case the model does not start at iter0=0
777    o fix mnc-pickup/restart for ptracers
778    o new package prifiles:
779      code to compute profile-based cost by Gael Forget
780      (modifs in ecco, ctrl, autodiff)
781    o Benign bug fix in initialization (spotted by M. Mazloff) of
782      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
783    
784    checkpoint58c_post
785    o adjoint: finish NLFS adjoint and provide reference output in
786      verification/global_ocean.90x40x15/results_ad_nlfs
787    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
788      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
789      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
790      with SEAICE_CGRID defined.
791    o move calendarDumps from "data" to "data.cal" and clean-up the code
792      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
793    o add useEXF & useCAL flags (for now, set in hard-coded way)
794    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
795      (were missing in NH mode, and wrong in quasihydrostatic mode).
796      waiting for Chris updated version of calc_gw to add those CALLs.
797    o fix bug in quasihydrostatic S/R ;
798      add a test for this option: global_ocean.90x40x15.qshyd
799    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
800      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
801    o add on/off flag useOffLine for package OFFLINE
802    o seaice:
803      - modify advection so that it works also on the C-grid
804      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
805        problem in multi-tile runs with C-grid
806      - add flags for clipping ice velocities and/or masking solver forcing
807      - fix drag (ocean on ice) formulation and a bug that caused noise in the
808        C-grid solver
809      - added a few comments to seaice_diffusion.F
810      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
811        are now exclusive)
812      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
813        required re-ordering the code a little:
814       + make DAIRN global variable (defined in SEAICE)
815       + move computation of the viscosities eta and zeta into a new separate
816         routine (because I need to recompute them in seaice_ocean_stress.F)
817    
818    checkpoint58b_post
819    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
820      update output.txt of exp. aim.5l_cs.thSI
821    o various mnc cleanups and improvements:
822      + shrink lookup tables by factor of ~4
823      + better error reporting when running out of lookup space
824      + able to handle longer path/file names (up to 500 chars)
825    o adjoint:
826      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
827      - TBD: "hidden" mom_vecinv recomp. in dynamics
828    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
829     (allow to differentiate between forcing components using new integer flags:
830      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
831     and add new flag to put Dissipation tendency out of Adams-Bashforth.
832    o ecco
833      - enable trend removal from SSH anomaly obs.
834    o adjoint
835      - a fix for PmEpR when #undef EXACT_CONSERV
836      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
837      - try to fix "hidden" recomp. in forward_step for NLFS
838        (NLFS seems broken sometimes after I checked it in)
839    o seaice:
840     - add c-grid version of the dynamic solver:
841       + three new routines that are the c-grid substitute lsr, dynsolver
842         and ostres
843       + put a few fields that were local to dynsolver into global common
844         blocks, so that I can move the computation of stresses etc into
845         seaice_lsr (saves coding but may break the adjoint).
846     - replace more hardwired parameters by runtime parameters
847     - add ice masks that mask the rhs of the implicit solvers where there
848       is no ice (commented out in seaice_dynsolver, because i am not sure
849       if this works properly), eventually this should replace the clipping
850       of ice velocities in seaice_dynsolver to +/-40cm/s.
851    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
852      include it only where its needed
853    o move balancing of fluxes before the call of external_forcing_surf
854    o seaice:
855      - correct units of turning angles (now they are really in degrees)
856      - move computation of GWATX/Y out of main routine into dynsolver
857      - initialize GWATX/Y in seaice_init
858    o Apply mask on Fresh-Water flux (needed for SSH forcing).
859      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
860    o seaice: add runtime flags for turning angles (default to zero)
861    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
862      and trend from exf forcing and ctrl control adjustments
863    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
864      (since checkpoint57x_post)
865    o change the default rotation period to 86164.s = the Earth rotation
866    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
867      and based on a reference stratification. Tested within hs94.cs-32x32x5.
868    o seaice advection: add code for choosing between the default (2nd order
869      central differences) and multiDim advection schemes provided by
870      pkg/generic_advdiff
871    o seaice:
872      - removed all references to SEAICE_GRID.h fields from
873        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
874        (cubed-sphere configuration will change a little)
875      - grid computations in seaice_init are obsolete now.
876      - cleaned up code a little so that is easier to read (hopefully).
877      - added new (better?) discretizations of default advection and diffusion
878        (turn on with SEAICEuseFluxForm)
879      - replace 1 in 3d global fields by kSurface in growth.F
880      
881    checkpoint58a_post
882    o seaice:
883      - bug fix in advect.F
884    o shelfice:
885      - separate shelfice load anomaly from pload (breaks with time
886        dependent forcing), => introduce constant field shelficeLoadAnomaly.
887        Its default is 0., but it may be computed more cleverly from (unknown)
888        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
889        done offline. A good approximation of the pressure load anomaly is
890        necessary to avoid large initial adjustment processes underneath
891        deep-reaching shelfice.
892      - small fix in ISOMIP shelfice_thermodynamics
893      - add more sophisticated thermodynamics of Hellmer (1989), this is
894        now the default
895      - give a few constants more intuitive names
896    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
897      if bulk formulae are used in long integration (especially EmPmR). Turn
898      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
899      if balancePrintMean, the imbalance that is substracted is printed to
900      STDOUT.
901    o fix bug (typo) in obcs_apply_eta.F
902    o add a new package shelfice which enables us to model the circulation
903      underneath shelf-ice with draughts of hundreds of meters.
904     - works
905     - to do: + include improved thermodynamics
906              + check whether kSurfC (from model/inc/SURFACE.h) can be used
907                instead of new field kTopC
908              + can we use topoFile, Ro_surf and existing code in ini_depth.F
909                instead of new field R_shelfIce and new code in ini_depth.F
910                and ini_mask_etc.F?
911              + adjust vertical mixing schemes?
912    o seaice pkg:
913     - add a cpp-flag to include a simple formula for a salinity dependent
914       freezing point of sea water at the surface
915     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
916       meridional stresses are now different (and hopefully correct)
917    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
918       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
919       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
920    o pkg/diagnostics: add options and parameters for regional-statistics
921       diagnostics ; define regions by reading a region-mask from a file
922       (might add other options later)
923    o pkg/bulk_force:
924     - add option and parameters to use AIM surface-flux formulae.
925     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
926       others forcing fields (defined in PARM05, parameter file "data") are loaded
927       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
928     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
929     - use the right EXCH call for uwind,vwind (to work on CS-grid).
930     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
931       and parameters (note: calcWindStress replaces .NOT.readwindstress).
932     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
933    
934    checkpoint58
935    o add "--embed-source" option to genmake2 which, when the supporting
936      tools can be compiled (as determined by genmake2) will turn on the
937      embed_files package which then embeds the entire MITgcm source code
938      (*.[fFhc] + Makefile) used for the build within the executable
939      - requested by CNH but off by default
940      - adds a paltry <9MB to the mitgcmuv executable in most cases
941      - only writes the output when useEMBEDSRC in eedata is true
942    o clean up 3-dim. relaxation codes:
943      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
944      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
945      * Thanks to Tom Haine for testing!
946    
947    checkpoint57z_post
948    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
949      affects output (@ truncation level) of exp. plume_on_slope ; updated.
950    o fix the pickup behavior for obcs in combination with ptracers
951    o fix a bug in ptracers_external_fields_load
952    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
953      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
954    o transfered surface NH pressure to eta field (if exactConserv).
955    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
956         and update lab_sea output.txt file.
957    o completing 3-dim. relaxation code: additional term
958         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
959      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
960      * At compile time, in "EXF_OPTIONS.h" set
961          #define  ALLOW_CLIMTEMP_RELAXATION
962          #define  ALLOW_CLIMSALT_RELAXATION
963      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
964          tauThetaClimRelax3Dim = 15552000.0,
965          tauSaltClimRelax3Dim  = 15552000.0,
966      * 3 cases:
967          1) Use a constant-in-time 3-dim. field
968          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
969          3) Real-time relax. to time-evolving prescribed field
970    o Adding Laplacian-type smoothness constraint on
971      initial and boundary (forcing) controls (ic, bc)
972      * enable at compile-time via
973        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
974      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
975      * Absolute scale somewhat unclear so far
976      * no area weighting was included since no other cost term does so far
977    
978    checkpoint57y_post
979    First step for a NLFS adjoint
980    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
981    o new init. routines for calc_r_star, calc_surf_dr
982    o still need to deal with ini_masks_etc
983    o testreport seemed happy
984    checkpoint57y_pre
985    
986    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
987    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
988    o add new offset feature to offline pkg (plus minor cleanup)
989    o cfc fixes for final year of integration
990    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
991      be in GCHEM_OPTIONS).
992    
993    checkpoint57x_post
994    o fix testreport Pb in multiple test experiment.
995    o cleanup our namelist syntax in verification:
996      - make it more F95 standards compliant (some work still needed)
997      - allows the vast majority of our tests to work with gfortran
998    o Non-Hydrostatic:
999     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1000     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1001    o Allow to apply AB on T,S rather than on AB(gT,gS):
1002     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1003     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1004       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1005     - need a "clever" read_pickup to restart from the other AB formulation
1006    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1007    o remove some unused variables (reduces number of compiler warnings)
1008    o adjoint
1009      * Disable useVariableViscosity for adjoint for time being
1010        (there are a number of extensive recomputations)
1011      * Initialize certain variables needed for adjoint
1012    
1013    checkpoint57w_post
1014    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1015                 fix the singleCpuIO RS version of MDSWRITEFIELD
1016       and add a WARNING if using globalFiles=T with multi-processors.
1017    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1018      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1019    o tracer advection scheme:
1020      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1021       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1022       was not very convenient).
1023      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1024       (further tests needed for the implicit DST & Flux-Limiter schemes).
1025    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1026      and sRef for convenience, handy, when you want to initialize
1027      ptracers in a large domain with a constant non-zero value. Also,
1028      untangle ptracers_init.F a little.
1029    
1030    checkpoint57v_post
1031    o change dome exp. to use variable viscosity in side-drag terms.
1032    o remove all the files from the cfc_offline test since they are now
1033      incorporated into tutorial_cfc_offline which has been producing
1034      identical results for a few days of testing
1035    o add new parameter: sideDragFactor to enable half-slip-side BC
1036      and change side-drag S/R to use viscosity from mom_calc_visc
1037      (can switch back by setting sideDragFactor=0.); affects results at
1038      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1039       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1040    o vorticity & strain are now computed without masking, to account for
1041      no-slip-side BC in variable viscosity calculation ; mask is applied
1042      anyway later on, before computing advection/coriolis terms.
1043    o modify exp4 to test new obcs support for reading from external files
1044      and for passive tracers
1045    o fix behavior of ptracers_monitor when monitor output is written to a
1046      netcdf-file; still not independent of monitor.F (writes in the same
1047      file).
1048    o change default value of tRef (put a uniform, meaningful value for ocean
1049      & atmos) and initialize sRef (was missing, as Martin mentioned).
1050    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1051      to be proportional to enstrophy dissipation length.  Thus,
1052       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1053      This is now consistent with Smagorinsky and with the manual.
1054    
1055    checkpoint57u_post
1056    o OBCS and PTRACERS: add open boundary support for passive tracers
1057      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1058        OB-values from file; this is not different from the way theta and salinity
1059        are treated
1060      - however, Orlanski-radiation conditions are not supported, and the model
1061        will stop if you use pTracers and Orlanski at the same time.
1062      - beefed up the rountine obcs_external_fields_load: now only those open
1063        boundary values are overwritten with values from files for which there
1064        are really files, otherwise the OB-fields remain untouched. This makes
1065        it possible to use different OBs at different ends of the domain (as
1066        with EXF)
1067    o reduce number of exch calls in shap_filt (s2).
1068    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1069      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1070    
1071    checkpoint57t_post
1072    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1073    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1074      same truncation, independent of the face number: affects affects several
1075      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1076    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1077      note that biharmonic viscosity + no-slip was not tested in any experiment.
1078    o fix bug in non-linear free-surf side-drag ; generate new output for
1079      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1080    o make mnc honor the writeBinaryPrec flag for most kinds of output
1081    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1082    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1083      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1084    o add brackets in multi-terms sum to get same truncation, independent of
1085      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1086      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1087    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1088      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1089      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1090      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1091      Suggested values of viscosity parameters found in mom_calc_visc.
1092      Many new viscosity diagnostics available.
1093    
1094    checkpoint57s_post
1095    o Add clearing-house for viscosity calculations, mom_calc_visc and
1096      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1097      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1098      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1099      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1100      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1101      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1102      ViscAhStrain and viscAhTension are now retired.
1103    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1104    o In response to JMC's bug report, genmake2 now ignores any soft-links
1105      that it finds in the *current* directory when searching for files.
1106      Soft-links found in any other source directories will still work as
1107      they did before.
1108    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1109      a C routine to unlimit the stack size
1110    o mnc-ify pkg/aim snapshot vars
1111    o mnc-ify pkg/land as requested by Daniel
1112    o various changes to mnc including:
1113      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1114      - output can now be grouped so that all files within a group
1115          change the ITER portion of their names in lock-step together
1116      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1117          and works with both EXCH1 and EXCH2 (but needs more testing)
1118      - writing works for all verification test cases w/ g77 on Linux
1119    
1120    checkpoint57r_post
1121    o make MNC variable initialization happen earlier
1122    o add diagnostics for (almost) each term of the momentum Eq.
1123    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1124    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1125    o remove MINIMAL_TAVE_OUTPUT option ;
1126      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1127    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1128      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1129    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1130    o add time-dependent SST, SSS control
1131    o cost terms in ecco/ modularized (new cost_generic.F)
1132    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1133    o new infrastructure for seaice model vs. obs misfits in seaice/
1134      * driver from the_main_loop.F is seaice_cost_driver.F
1135      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1136      * gradient check in Exp. 6a of natl_box_adjoint/
1137    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1138      (see README file)
1139    
1140    checkpoint57q_post
1141    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1142    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1143      - bug was reported by Jean-Michel and Ian Fenty
1144    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1145      update exp. cpl_aim+ocn output.
1146    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1147      Needed for high-res. runs with large global files
1148      to be able to limit tapelev size
1149    o Changed some tests for adjoint:
1150      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1151      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1152      * global_ocean.90x40x15/ back to default 3-level checkpointing
1153    o Modifications to enable scripted COMMON to MODULE conversion
1154      * verification/OpenAD/code/ has necessary scripts and description;
1155      * converts, compiles and runs successfully;
1156    
1157    checkpoint57p_post
1158    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1159    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1160      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1161    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1162    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1163      (was already the case for dissipation with mom_vecinv,
1164       and also the case for grad.PhiHyd when staggered-timeStep)
1165      This will allow to put dissipation out-off the AB time-stepping.
1166     Unfortunately, affects truncation error. Update output of exp. that "fails"
1167      (cg2d matching number) and leave the others for later: front_relax(10),
1168      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1169      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1170    
1171    checkpoint57o_post
1172    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1173      (2) its ready to be documented during the 20050801 DocFest
1174    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1175      for ideal_2D_oce and lab_sea on linux_ia32_g77
1176    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1177      in global1x1_tot/code_seaice_adj to access indices 32, 33
1178      (worth another tag)
1179    
1180    checkpoint57n_post
1181    o adding precip control xx_precip 32
1182    o adding swflux control xx_swflux 33
1183    o Replacing 10 forcing penalty cost routines by 1 generic.
1184    o Implementing partitioning in time-mean and variable adjustment
1185      for atmos. state.
1186    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1187    o in natl_box_adjoint:
1188      * updated exp 1 to 10
1189        (but does not have time-mean vs. variable split results yet)
1190    o updated global1x1/*_seaice_adj/
1191      to incorporate latest changes
1192    o enable useSingleCpuIO for mdsio vector routines
1193      (applies in particular to tapelev I/O)
1194    o removed inefficient K-loop in all active_file*control*.F
1195    
1196    checkpoint57m_post
1197    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1198      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1199    o pkg/exch2: filling of face-corner halo regions is optional
1200      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1201    
1202    checkpoint57l_post
1203     tag before updating tutorials (pre-release-2)
1204    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1205       for output and interpolation of input fields onto model grid)
1206    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1207       Affects results of exp. rotating_tank ; update output.txt.
1208    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1209          and taking the square quantity and/or using a fraction-weight field.
1210    o fix aim_diagnostics_init.F mate numbers.
1211    o add mnc output capability to diagnostics/diagstat and update
1212      our cvsignore files for the ACSII output generated
1213    
1214    checkpoint57k_post
1215    o lab_sea now uses diagnostics package and provides a suite of
1216      new EXF diagnostics output.
1217    
1218    checkpoint57j_post
1219    o exf
1220      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1221        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1222        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1223      * extended diagnostics output
1224        - now includes all EXF variables
1225        - hs, hl moved to common block
1226        - separate S/R for diagnostics, called after ctrl vector is added
1227        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1228        - EXFqnet contains true Qnet (i.e. includes qsw)
1229      * updated verif. lab_sea, global_with_exf
1230      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1231        to ensure that diagnostics sees a true EXFqnet
1232    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1233    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1234      several times with different frequencies.
1235    o mnc-ify the thsice package as requested by Daniel Enderton
1236      - the monitor--MNC output needs work
1237      - many attributes need to be added (most are currently blank)
1238    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1239      - many attributes need to be added (most are currently blank)
1240    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1241    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1242    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1243      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1244         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1245    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1246     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1247    
1248    checkpoint57i_post
1249    o Diagnostics package was changed: diagnostic allocation is now deactivated
1250      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1251    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1252      add 1rst Order upwind vertical Shear.
1253    o add a quick fix for A/B checkpointing in OFFLINE mode
1254    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1255      end-run around the C/Fortran linking horror in eesup/src/timers.F
1256    o added pkg/runclock: allows user to terminate run based on wall clock
1257    o added non-hydrostatic scaling parameter: nh_am2
1258    o pkg/my82: futile attempt to make results compiler-independent by adding
1259      some "_d 0", etc. no effect.
1260    o for mnc output, fill the 'T' coordinate var with myTime and create a
1261      separate 'iter' variable for iteration count
1262    o pkg/diagnostics:
1263      add new capability: output of Global/Regional & per-level statistics ;
1264      tested against monitor output (including land & thSIce) on various exp.
1265    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1266    
1267    checkpoint57h_done
1268      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1269      data.diagnostics, data.gchem, data.ptracers) is done.
1270    
1271    o pkg/diagnostics: prepare for Global/Regional statistics.
1272      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1273    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1274      and rename it: DIFFERENT_MULTIPLE
1275    
1276    checkpoint57h_post
1277    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1278    o pkg/diagnostics: change output frequency, now in seconds (instead
1279      of Nb of iterations). This requires to change data.diagnostics.
1280    checkpoint57h_pre
1281    
1282    o in mnc, let the user create the output dir if both mnc_outdir_date
1283      and mnc_outdir_num are false
1284    o add fflags() to pkg/diagnostics which allows one to specify, on a
1285      per-file basis, the file precision [default behavior is unchanged]
1286    o added diagnostics to pkg/kpp, including computation of mixed layer
1287      depth based on a temperature/density criterion
1288    o updated verification/natl_box to test the new pkg/kpp diagnostics
1289    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1290    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1291    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1292      not mnc -- this mistake was found by JMC and is now corrected
1293    
1294    checkpoint57g_post
1295    o add Adams-Bashforth 3rd Order time stepping:
1296      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1297      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1298    checkpoint57g_pre
1299    
1300    o make lambda[Theta,Salt]ClimRelax spatially varying
1301      (default remains spatially uniform constant based on tau)
1302    o added new control variables
1303      * init. uVel, vVel, etanN
1304      * lambda[Theta,Salt]ClimRelax
1305    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1306      (suggested by G. Forget)
1307    
1308    checkpoint57f_post
1309    o add parameter "baseTime" = model base time = time at iteration zero
1310      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1311      account for baseTime shift
1312    o move Coriolis arrays from PARAMS.h to GRID.h
1313    checkpoint57f_pre
1314    
1315    o mnc-ifying the seaice package
1316    o introduced an alternative length scale calculation for use in the limiting
1317      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1318    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1319    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1320      as well as grad(vort3).  Made it compatible with both approximate form
1321      for the cubed sphere and full form of these gradients.  Added flag
1322      useFullLeith to select between approximate and full form.  
1323    o add "d0" in getcon.F to reduce differences between compilers/platforms
1324      update output.txt of exp. fizhi-gridalt-hs
1325    o change port_rand funtion to allow to set the seed.
1326    o fix obscure MNC bug involving conversion between reals and integers
1327      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1328        new version is now more standards-compliant
1329    o adjoint-related modifications
1330      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1331      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1332      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1333    
1334    checkpoint57e_post
1335    o Adding eddy stress controls a la Ferreira et al.
1336    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1337    
1338    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1339      update output.txt of exp. fizhi-gridalt-hs
1340    o add more "Z" dimensions and associated coordinate vars to MNC
1341    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1342    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1343      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1344      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1345      months and years.  Requires pkg/cal.
1346    o diagnostics: add pickup functionality
1347      - off by default for backwards compatibility
1348      - current version only uses MDSIO -- MNC will be added
1349    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1350    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1351    
1352    checkpoint57d_post
1353    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1354    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1355      output from the diagnostics package
1356    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1357    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1358      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1359    o add coordinate variables to the MNC output from the diagnostics package
1360    o change MNC-flags default value: true when useMNC=TRUE
1361    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1362      the ability (off by default) to read the grid information using MNC
1363    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1364    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1365    o do snap-shot diagnostics at the middle of the time-interval (instead of
1366      at the end).
1367    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1368      new test for AIM with thSIce + slab-ocean
1369    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1370    o move state variable diagnostics to the beginning of the time step ;
1371      (note: still needs some work specially for snap-shot diagnostics)
1372      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1373    
1374    checkpoint57c_post
1375    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1376    o generate new output.txt files on faulks with g77 & the new -ieee option
1377    checkpoint57c_pre
1378    
1379    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1380      update output.txt of exp. global_ocean.90x40x15
1381    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1382      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1383    o add saltFlux(+File) forcing capability with periodicExternalForcing
1384    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1385    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1386    o improvements for the MNC output from DIAGNOSTICS:
1387      - correct handling of the unlimitied dimension
1388      - all dims now have associated coordinate variables
1389      - variables located at U, V, and Corner ("Z") points are now written
1390        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1391        *all* data points are output
1392    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1393    o added pkg/seaice/seaice_monitor.F
1394    o mdsio_readfield.F can now read files visible only to master MPI process.
1395    o pkg/seaice: some test code for ice-modified ocean stress
1396    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1397      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1398      spurious negative numbers for precipitation and humidity.  Will cause
1399      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1400    o pkg/ctrl/
1401      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1402        May be enabled via doPackDiag
1403      *  introduce z-scaling of
1404         + gradient (doZscalePack) and
1405         + control (doZscaleUnpack)
1406    o pkg/mdsio/
1407      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1408      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1409    
1410    checkpoint57b_post
1411    o simplify options in diagnostics_fill arguments (remove weird combinations)
1412    o fix MNC coordinate variables so that they now contain per-face index
1413      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1414      general, EXCH2 grids are only aligned to a "local" coordinate system
1415    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1416    o Implement instantaneous output within pkg diagnostics:
1417      setting a negative frequency in data.diagnostics produces
1418     "snap-shot" output (as opposed to time-average if freq > 0)
1419    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1420      NOTE: change ptracer diagnostics name: use 2 characters to work with
1421            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1422    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1423      becomes the coordinate variable for the 'T' dimension
1424    o add CF-style coordinate variables to MNC
1425      - just a first cut:  numbers are meaningless on the cubesphere and
1426        missing along the T axis but otherwise it works!
1427    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1428    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1429    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1430      this is based directly on what the model compute, so that the content of
1431      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1432    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1433    o clean up build options files for SunOS, in particular
1434      - remove -traditional from xmakedepend
1435      - change -xarch=v9 to -xarch=native for f77
1436      - restore use of make (not gmake)
1437      - add CC=gcc if using g77
1438    o changes per discussion of AM, JMC, & EH3 today:
1439      - move redundant "grid" variables out of "state" -- in preparation of
1440        creating proper CF-style coordinate variables and in recognition
1441        that any/all grid variables can be easily copied (eg. w/NCO) from
1442        the grid files into any of the other NetCDF files
1443      - *always* output grid variables with MDSIO (this will eventually be
1444        changed)
1445      - output MNC grid file if useMNC is true
1446    o every instance of _END_MASTER() has been found and replaced with
1447      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1448      preprocessors
1449    o re-arrange diagnostics pkg initialisation:
1450     - allow each package to extend the available diagnostics list
1451     - add some checking and fix small problems (multi-threaded, ...)
1452     - new S/R diagnostics_fill (replace fill_diagnostics):
1453       look through the short list of active diag. (instead of the long list)
1454       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1455    
1456    checkpoint57a_post
1457    o this set of changes restores TAMC compatibility
1458      tested for global_ocean.90x40x15 adjoint on trough
1459      (what a pain)
1460    
1461    checkpoint57a_pre
1462    o some modifs in tools/build_options for sunos
1463    o call ctrl_pack for ctrl at end for optimcycle=0
1464    
1465    checkpoint57
1466    o add horizontal bi-harmonic viscosity for vertical velocity
1467      - new parameter viscA4W (defaults to viscA4)
1468      - affects only non-hydrostatic code
1469      - to be done: no-slip lateral boundary conditions
1470    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1471    o implement Implicit Vertical advection for pTracers
1472    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1473      (implemented also for implicit vertical diffusion & advection)
1474    o OBCS: extend application of tracer open boundary conditions
1475      to a strip beyond the boundary of width Olx/Oly
1476    o add call monitor to TAF set of required calls (flow directives)
1477      and include in natl_box_adjoint
1478    o untangle a few ifdefs related to cost, ctrl, autodiff
1479      untangel a few ALLOW_ECCO_OPTIMIZATION
1480    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1481      (theta2, salt2 in ecco_cost_weights)
1482    
1483    checkpoint56c_post
1484    o OBCS as control variables
1485      - update ctrl_ad_diff.list, obcs_ad_diff.list
1486      - remove balance of obcs controls from default
1487      - fix index bug nobcs in ctrl_init
1488      - fix dummy fields filen in ctrl_pack
1489      - add dummy weights for obcs
1490    o lsopt: comment out fort.94 output
1491    o optim:
1492      - remove unnecessary header files
1493      - adjusted namelists
1494      - add xerbla.F to Makefile
1495    o exf:
1496      - multiple modifications of exf_check_range
1497      - unit change in exf_init_runoff from [m/year] to [m/s]
1498    o mdsio:
1499      - i/o-vector change debugLevel from debLevA to debLevB
1500    
1501    checkpoint56b_post
1502    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1503      is called from DO_THE_MODEL_IO
1504      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1505      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1506      - clean up PTRACERS_WRITE_TIMEAVE a little
1507    o add another verification experiment that tests both the cfc-pkg and
1508      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1509      reactive tendencies treated inline with regular timestepping
1510    o testreport previously did a lousy job of comparing small numbers, so
1511      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1512      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1513      testreport.
1514    o ptracers_monitor: bug fix for MPI
1515    
1516    checkpoint56a_post
1517    o GCHEM: finish reorganizating the package
1518      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1519        (introduces another 3D-array for each passive tracer, but only if
1520        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1521        gchemTendency is not needed because the timestep is done separately)
1522      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1523      - GCHEM is now---more or less cleanly---separate from PTRACERS
1524      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1525        so clear to me how that should be done in a general way.
1526    o CFC: improve formatting of output in CFC_ATMOS
1527    o PTRACERS:
1528      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1529        that ALL experiments with ptracers enable can be checked. This makes
1530        GCHEM_MONITOR obsolete.
1531      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1532        monitorFreq
1533      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1534    o add PTRACERS (PTR0[1-5]) to testreport output
1535    o exf_check_range:
1536      * default changed to .TRUE.
1537      * will check values for niter0 if debLevA, every timestep if debLevB
1538      * STOP in exf_check_range if 'out of range'
1539      * range chosen generous to allow for potential extema
1540      TBD: a version with stricter range
1541           permitted range would be runtime parameters
1542  o GMredi:  o GMredi:
1543    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1544    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.

1550      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1551        this flag is now only visible within GCHEM-pkg routines.
1552      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1553        be replaced by a 3D array that is computed before thermodynamics; for
1554        this, the tracer ID iTracer had to be included into the parameter list
1555        of ptracers_forcing
1556      - set up forward_step to call gchem_forcing, that will replace
1557        gchem_forcing_int in ptracers_forcing
1558      - cleaning up
1559  o small cleaning of exch2: remove files that are also in eesupp/src  o small cleaning of exch2: remove files that are also in eesupp/src
