7    checkpoint59g
8    o adjoint testing: in preparation for changing testreport:
9      - output format: cost and grad written on separated lines
10      - ad output results in directory "results" (instead of "results_ad")
11    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
12    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
13    o pkg/ecco: allow user defined cost function contributions
14    o testreport:
15      Allow to choose (per experiment) the list of tested output variables
16       and the main variable (used to issue a pass/FAIL ) ;
17      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
18      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
19      Also modify printing of summary:
20       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
21       b) echo the list of tested variables in the individual summary.txt of
22          each experiment.
23    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
24      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
25      (but still depend on the tile decompostion of the domain).
26    o pkg/seaice: change a discretization detail to make the B-grid code
27      "more symmetric". This change is likely to remove all "ridges/leads" that
28      where quasi-aligned with the grid in B-grid solutions. It may also be
29      the solution to the stress coupling issues with the B-grid.
30    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
31      remove .cvsignore from input dir. (since testreport no longer run here).
32    o pkg/thsice:
33     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
34     - fix reshaping of sea-ice just after advection:
35       melt all the ice only if ice-volume is too small.
36     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
37       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
38     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
39    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
40      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
41    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
42      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
43      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
44      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
45      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
46      -> update output.txt
47    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
48     this affects truncation error: -> update output.txt of exp:
49      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
50      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
51    
52    checkpoint59f
53    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
54    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
55      a bounded range (in forward mode)
56    o pkg/ecco, ctrl, autodiff and mom_common:
57     internal parameter controls, completements of implementations
58    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
59    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
60      (not seem any difference in testing results).
61    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
62       at face corners.
63    o pkg/generic_advdiff:
64     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
65      loop range indices for computing vertical advection tendency
66      and do the calculation in the interior only (no overlap) ;
67      for now, only implemented for SOM advection (to save CPU time).
68     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
69    o exch2 adjoint
70      First set of changes:
71      - add exch2 hand-written adjoint templates
72      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
73        This will require cleanup in pkg/autodiff/*.F
74        (changed routines currently kept separate in verif. code/)
75      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
76        that used to hide exch2 or cubed-sphere specific code
77        (commented via 'cph-exch2')
78    o pkg/seaice
79      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
80    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
81       output of global_ocean.cs32x15.thsice .
82    
83    checkpoint59e
84    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
85      for B-grid vector (not yet tested) and C-grid vector (<- only used
86      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
87    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
88      (#ifdef ALLOW_SALT_PLUME)
89    o gather_2d/scatter_2d: removed halo regions
90    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
91      scheme and the corresponding test case (under front_relax dir). For now,
92      only available with Skew-flux form and not yet tested in realistic set-up.
93      adjoint: store directives updated, but gradient checks deteriorated,
94      so maybe GM/Redi adjoint is now broken.
95    o seaice adjoint
96      * add AREA, HEFF, HSNOW as control variable
97        (should not change lab_sea results)
98      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
99    o pkg/seaice:
100      * added computation of saltFlux in seaice_growth;
101        For time being, sea ice salinity is assumed constant
102        contribution of snow flooding to freshening of sea ice is neglected.
103        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
104        defaults to 0.0 in order to maintain backward compatibility.
105        Typical values for SEAICE_salinity are 4 to 10 g/kg.
106      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
107      * added SEAICE_availHeatFrac, which specifies fraction of surface level
108        heat content used to melt or grow ice
109      * commented out cap of HICE: it helps keep ice thinner
110      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
111      * applied OBCS T/S mask to HEFFM sea ice mask
112    
113    checkpoint59d
114    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
115     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
116     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
117    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
118     and change default value of parameter "GM_Small_Number";
119     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
120       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
121       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
122    o pkg/ecco: cost function when applying pkg/smooth to controls
123    o pkg/ctrl: add forcingPrecond run time parameter
124    o pkg/seaice:
125     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
126     - fix bug in metric terms of u-equation in LSR solver (implicit part),
127       changes verification/lab_sea
128     - rearrange implicit part of u-equation in LSR solver to make it easier to
129       read, understand, and debug. This causes changes at the truncation level.
130     - fix (serious) bug in the boundary conditions (sign error in the implicit
131       part) of the LSR solver. Changes all LSR results.
132     - fixed problem with HSNOW initialization to avoid thick snow when AREA
133       is initilized with small values - does not change lab_sea results.
134     - added HsnowFile initialization capability
135    o pkg/smooth: addition to model/src and pkg/ctrl so allow
136     initialization of pkg/smooth and application to control vector
137    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
138    o dependencies: pkg/profiles requires pkg/cal
139    o pkg/profiles:
140     - added option ALLOW_PROFILES_GENERICGRID
141         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
142         that interpolation information (grid points and coefficients) is provided
143         within the netcdf input files.
144         -> sample matlab scripts can be found in MITgcm_contrib/gael
145         that allow you to prepare netcdf input files.
146     - also modified: cleaner include statements, cleaner error print statements,
147       cleaner stops when error, and more tests of the netcdf input files consistency.
148    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
149    o pkg/seaice:
150     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
151       requires a new routine: seaice_diagnostics_fill.F
152     - make sure that seaice does not move if not forced (pressure replacement
153       method, Hibler and Ip, 1995), changes results
154     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
155     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
156       It is turned off by default (=-1.), because it changes the results.
157     - make it possible to read AREA from a file, too.
158    
159    checkpoint59c
160    o add S/R and diagnostics for oceanic mixed-layer depth
161    o move GMRedi call after all vertical mixing schemes (including KPP)
162    o pkg/thsice:
163     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
164      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
165    o pkg/obcs:
166     - bug fix for balance code
167    o pkg/seaice:
168      - allow values of SEAICE_elasticParm > 1
169      - add new parameter SEAICE_evpTauRelax as an alternative
170        to SEAICE_elasticParm
171      - make lsr boundary conditions free slip (by default), changes result
172      - add code for no slip boundary conditions for lsr
173      - set minimum of zeta to zero (and not 4e8) (changes results)
174      - add a cap on AREA after advecting AREA if seaice_growth is not called
175    o change calculation of Visbeck K:
176      - no longer depend on tapering scheme; instead, compute slope (limited
177        by GM_maxSlope). this is equivalent to what was comuted before with
178        clipping or linear tappering.
179      - fix vertical averaging (wrong by 1/2 level)
180      - leave the old version (but will not be maintained) within
181        #ifdef OLD_VISBECK_CALC / #endif
182      - update output of exp. ideal_2D_oce
183    o change error catch in calc_r_star to improve vectorization
184    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
185      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
186    o adjoint:
187      Re-organized adjoint checkpointing according to Matt Mazloff
188      (but with modifs/completions/cleanups)
189      Storing is now bundled into large arrays to optimized I/O
190      (and second step in cleanup of the_main_loop)
191    
192    checkpoint59b
193    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
194      - export/import (between ocean & coupler) fields needed for ocean DIC.
195    o pkg/seaice:
196      - get rid of three more exchanges seaice_calc_viscosities (required
197        different loop boundaries in seaice_lsr and seaice_ocean_stress)
198      - bug fix in seaice_ocean_stress (update of lab_sea required)
199      - reduce loop boundaries to necessary minimum also in seaice_evp
200      - go back to the old way of computing deltaC/Z as the adjoint likes that
201        better
202    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
203      passive tracer to an Age Tracer) + update output.txt
204    o pkg/exf:
205      - implement A-grid / C-grid selection for wind-stress input files.
206      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
207      for now, in exf_bulk_largeyeager04.F only :
208      - change implementation for case where windspeed + 2. components wind-stress
209        are read-in. AND use rhoConstFresh to convert evap.
210    o pkg/seaice:
211      - use correct EXCH_UV for wind-forcing (on A-grid).
212      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
213        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
214    o pkg/exf:
215      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
216      EXF_INTERPOLATION:
217      - merge global_with_exf/code version of exf_interp_read.F
218        to the main code ;
219      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
220        reading the file ; Important: This options needs to be defined to recover
221        previous code.
222        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
223      - no longer loose real*8 precision along the way when using exf_iprec=64.
224    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
225      - change discretisation of evp-solver in order to avoid another exchange
226        (changes lab_sea) and clean up a little
227      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
228        help the adjoint (this also changes the results slightly)
229      - add a few "_d 0" where they had been missing in seaice_evp.F
230      - cleaning up: remove unused seaice_calc_rhs.F
231    o pkg/exf: some cleaning-up:
232      - change various "constants" into runtime parameters
233      - cleaned-up Large&Yeager04 routine which should eventually
234        replace exf_bulkformulae.F (changed names of S/R and CPP)
235        and merged various ALLOW_ATM_WIND options
236     only used with thsice pkg (in thsice_get_exf.F):
237      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
238        which are used when useStabilityFct_overIce=TRUE (= the default)
239      - change default values of ice & snow emissivity and scale downward LW
240        by ice & snow emissivity.
241    o pkg/thsice:
242     fix few little problems, in thsice_calc_thickn.F:
243      - growth vertically (and not laterally) if iceFrac == iceMaskMax
244      - melt only laterally if hIce < hThinIce (as the comments say)
245      and in thsice_extend.F:
246      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
247      - start to form ice as soon as the minimum ice-volume is reachable.
248     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
249      and cpl_aim+ocn
250    o pkg/kpp
251     - move computation of surface related input fields to KPP into a new
252       subroutine kpp_forcing_surf.F
253     - remove wrong (within bi,bj loops) EXCH calls.
254     - little cleaning (add argument myThid in last position, cvs header ...)
255     - for now, fix conservation problem by exchanging KPPviscAz (may not
256       be the best fix)
257    o pkg/seaice
258     - check for inconsistent evp parameter/cpp-flag combination
259     - remove leftover errIO flat for obsolete name list error handling
260    o OpenAD
261     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
262    
263    checkpoint59a
264    o pkg/seaice: some parameter clarifications and a little bit of clean up
265    o pkg/thsice: rename run-time parameters:
266       himin       -> hIceMin
267       himin0      -> hThinIce
268       hihig       -> hThickIce
269       i0          -> i0swFrac
270       transCoef   -> bMeltCoef
271       frac_energy -> fracMelting
272      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
273       with default values (for now) that do not change the results.
274      remove old version of thsice vars advection in pkg/seaice.
275    o in FFIELDS.h:
276      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
277      - make pLoad & sIceLoad always available (but still only used if
278         ATMOSPHERIC_LOADING is #define).
279    o pkg/kpp: replaced _KPP_RL with _RL
280    o bug fixes for vertical diffusivity computations when both KPP and
281        3D diffusivity arrays are used.
282    o pkg/seaice: fix bug in evp solver, while doing that
283      - change (improve?) discretization of stress computations for both
284        cgrid-lsr and evp solver
285      - add a new routine to compute strain rates
286      - the above changes lab_sea results
287      - add no slip conditions for evp solver (off by default), lsr-version
288        may follow
289      - fix exchange for shear at Z-points (does not change lab_sea)
290      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
291        (to force the user to pick a time step since there is not "safe" way
292        of choosing it)
293      - add principal stress diagnostics
294      - rearrange fields for evp a little to avoid having to call a: too many
295        exchanges and b: exchanges for stress trensor components which we do
296        not have.
297      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
298        of evp, complete rewrite for lsr case (latter is does not yet work
299        in all cases)
300    o pkg/kpp: add code to have mixing in shelf ice caverns
301      - add myThid to all kpp routines (long overdue)
302    
303    checkpoint59
304    o pkg/exf:
305      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
306        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
307      - move exf header files from lower_case.h to UPPER_CASE.h ;
308        add missing cvs Header & Name
309      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
310      - add namelist param. selectStressGridPosition, exf_monFreq
311      - retire many _CLIM routines, and remove data.exf_clim
312        + params moved to data.exf
313        + climsst, climsss now handled by exf_set_gen, i.e.
314          climss?period=0 refers to constant field,
315          climss?period=-12 to monthly forcing
316      - split up namelists in data.exf
317    o pkg/seaice:
318      - remove seaice_exch and seaice_exch_uv
319      - remove superfluous exchange of theta
320      - add myThid to seaice_budget_ocean/ice
321      - add new interface for atmospheric wind forcing (C-grid only)
322        + new routine
323        + two new field (taux, tauy for stress over ice)
324        + removed one global field (DAIRN) for C-grid case only
325    o pkg/thsise
326      - 2nd set of modifs for thsice adjoint in conjunction with exf
327    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
328    
329    checkpoint58y_post
330    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
331      vertical diffusivity, similar to that in MOM4; turned on using
332      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
333      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
334    o Added capability for 3D specification of background vertical diffusion
335      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
336      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
337      "data" file that contains the 3D vertical diffusivity coefficients.
338    o ice dynamics (pkg/seaice) with thsice thermodynamics:
339      - add code within pkg thsice to advect & diffuse sea-ice fields
340      similar to (and will replace) what has been added in  seaice_advdiff.F,
341      but: - conserving Mass, Heat & Salt.
342           - better when using non-linear advection scheme (not yet fully tested)
343           - can also be used in atmospheric set-up (for now, only the diffusion).
344    
345    checkpoint58x_post
346    o IO option for global-file compact format:
347      - add options when generating topology (utils/exch2/matlab-topology-generator)
348      - add I/O capability (pkg/mdsio).
349      - adapt utils/matlab/rdmds.m to read this format.
350      for now long-line format not yet supported by pkg/mdsio (& exch2).
351    o shelfice: add a few diagnostics
352    
353    checkpoint58w_post
354    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
355      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
356      (and replace horiVertRatio in NH code).
357      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
358                         and tutorial_plume_on_slope (sensitive to truncation)
359    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
360      directly to drive seaice model (C-grid only)
361    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
362     - reintroduce computation of wind from stress,
363     - compute tau (in exf_bulkformulae.F) from windstress averaged to
364       mass points to avoid tau = 0
365     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
366    o rdmnc.m: make it work with "global" files created with gluemnc
367    o rdmnc.m : some improvements in dealing with singleton dimension
368      (tested on all testreport mnc output files).
369    o genmake2: disable pkg/profiles if netcdf test fails.
370    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
371    o move call to cal_readparms up to make calendar parameters/variable available
372      to all packages
373    
374    checkpoint58v_post
375    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
376      useDynP_inEos_Zc tested.
377    o pkg/exf: changes to properly interpolate/mask/scale initial fields
378    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
379      and portions thereof.  See read_cs.txt for description and examples.
380    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
381      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
382      following the great-circle arc between those 2 points.
383    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
384      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
385    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
386     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
387     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
388     - still needs work (not working with some options ; efficiency to improve)
389       and serious testing.
390     - use this scheme for temperature & salinity in 2 advection test exp.:
391       advect_xy & advect_xz, respectively.
392    
393    checkpoint58u_post
394    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
395    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
396    o testreport: add option "-skipdir" to skip some test.
397    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
398      momentum calculation.
399    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
400    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
401      remove checkpoint.F and the_correction_step.F (no longer used);
402      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
403    o add option (linFSConserveTr) to correct for tracer source/sink due to
404      Linear Free surface
405    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
406    o pkg/thsice: fix reading mnc-pickups
407    
408    checkpoint58t_post
409    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
410    o pkg/mdsio:
411     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
412       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
413       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
414     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
415     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
416       either MDS_READ_FIELD or MDS_WRITE_FIELD )
417     - new S/R (to replace MDSWRITEMETA), which allows to write more
418       informations (variable names, time ...) to meta files.
419     - modify rdmds.m to give back the meta file content.
420    o pkg/diagnostics: change vertical interpolation to be safer, and more
421       flexible (define p-levels to interpolate to in data.diagnostics);
422      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
423       diagnostic pointer.
424    o pkg/seaice: more cleaning up of seaice_growth, added many comments
425    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
426    o fix multi-category seaice:
427     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
428       SEAICE_MULTICATEGORY
429     - fix short wave heat flux
430    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
431       and allow to use EVP solver. Change forward lab_sea: test both EVP
432       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
433    o Initial check-in of lab_sea adjoint
434      (very similar to natl_box_adjoint/code_seaice)
435      * used C-grid and EVP solver
436      * used KPP, GM/Redi
437      * uses inAdExact=.TRUE.
438      * gradient checks fail for both ADM and TLM
439        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
440        f.d. gradients actually seem more problematic than ADM, TLM gradients;
441        issue is related to forward mismatch between g77 an ifort
442    o pkg/seaice: overhaul of thermodynamics
443     - growth.F and groatb.F are replaced by new routine seaice_growth.F
444     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
445     - move a few global fields out of SEAICE.h into seaice_growth.F and
446       make them 2D (FICE/QNETO/ ...)
447     - remove FO (it is the same as QNETO)
448     - introduce a few local fields to avoid modifying external fields such
449       as atemp, etc.
450    
451    checkpoint58s_post
452    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
453      changed exf_set_gen.F so that
454        genperiod=0 means input file is one time-constant field and
455        genperiod=-12 means input file contains 12 monthly means
456    o CG2D: use pre-computed solver main-diagonal (stored in common block);
457      this affects truncation error ; generate new output file for exp. which
458      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
459        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
460        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
461        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
462        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
463        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
464    o start implementation of deep-atmosphere and anelastic formulation
465    o verification: remove 2nd copy of input files and use script "prepare_run"
466      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
467    o mom_common/vecinv/fluxform: fix a few initialisation isssues
468    o profiles: fix for multithreaded case
469    
470    o diagnostics: rename few diags:
471      s/'PRESSURE'/'RCENTER '/g
472      s/'TICE    '/'oceFreez'/g
473      s/'TAUX    '/'oceTAUX '/g
474      s/'TAUY    '/'oceTAUY '/g
475      s/'SWFLUX  '/'oceQsw  '/g
476      s/DIFx/DFxE/g
477      s/DIFy/DFyE/g
478      and add few ocean-forcing diagnostics:
479      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
480    o modifications to pkg/seaice/growth.F and budget.F, which change results of
481      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
482      as actual snow thickness.  It now refers everywhere to effective snow
483      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
484    
485    checkpoint58r_post
486    o modifications to pkg/seaice/growth.F, which change results of
487      lab_sea experiment: fixes pertain to melting snow over open water, to
488      masking EVAP under sea ice, and to using the correct AREA variable for
489      computations of EVAP, PRECIP, HSNOW, and GHEFF
490    o add ability to read bathy, salt, and theta using MNC (off by def)
491    o add flooding algorithm and advection of HSNOW for pkg/seaice;
492      both are turned off by default and do no change any results
493    o seaice advection with pkg/thsice: a step toward the use of non-linear
494      advection scheme, but #ifdef or commented out for now (requires more EXCH).
495    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
496      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
497      in natl_box (affects results @ truncation level: update output.txt)
498    o multi-threading and IO:
499      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
500      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
501        (needed to work with SingleCpuIO): tested in all verif. exp.
502    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
503      affects the results (but none of the verification test uses this scheme).
504    o Adding some pkg/diagnostics capability to pkg/seaice
505      (will certainly be subject to changes)
506    o ctrl: adding new control variables:
507      lwflux, lwdown, evap, snowprecip, apressure, runoff
508    
509    checkpoint58q_post
510    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
511      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
512      high_res_cube configuration by 4% on Columbia.
513    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
514      add (in global_with_exf/code) a version of EXF_INTERP_READ without
515      dynamical allocation (seems to work in multi-threaded).
516    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
517      single CPU io) so that TAF does not have to see EESUPPORT.h
518    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
519    
520    checkpoint58p_post
521    o obcs: stop if obcs is used with useCDscheme = .true.
522    o shelfice:
523     - fix a sign error so that no slip at shelfice interface works
524     - remove stop for combination non-hydrostatic code and shelfice. That does
525       not mean, that the results are correct, but at least they are numerically
526       stable
527    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
528    o added adjoint exch routined for all exch*3d* routines
529      and updated flow directives
530    
531    checkpoint58o_post
532    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
533      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
534    o change controling S/R for writing pickup file (new S/R do_write_pickup)
535      and clean-up reading/writing of pickup files.
536    o fix local version of read/write pickup (NH part) in rotating_tank/code
537    o simplify EXCH interface:
538     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
539     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
540    o added the regrid package
541    o shelfice:
542     - add a simple boundary layer scheme to reduce noise
543     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
544    
545    checkpoint58n_post
546    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
547       local variable (not in common block).
548    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
549      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
550      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
551        to work with SingleCpuIO.
552    o add "_d 0" to real constant of pkg/cfc subroutines ;
553       update exp. cfc_exemple & tutorial_cfc_offline output files.
554    o multi-threading and IO:
555      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
556        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
557      - barrier before and after reading.
558      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
559      - avoid using MDS_WRITELOCAL for LAND pkg output.
560      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
561        common-block variables ; Allows multi-threading with master-thread IO.
562    o change default MAX_NO_THREADS from 32 to 4 ;
563      and stop cleanly when MAX_NO_THREADS is too small.
564    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
565    
566    checkpoint58m_post
567    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
568       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
569    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
570       keep global_ocean.90x40x15 (for AD testing) with former secondary test
571       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
572    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
573        add MITgcm_tutorials (= code + all the tutorials)
574    o ecco, option to compute cost for total ssh (mean+anom)
575    o consistent with addition of ptracer and ssh in pkg/profiles
576    o profiles: adding ptracer and ssh
577    o testreport: change multi-test output-file name
578      (from output.txt.{name} to output.{name}.txt)
579    o profiles: now ok for mutli-tiles case
580    o seaice: add 4 parameters for different advection schemes for area,
581      (effective) seaice thickness, enthalphy, and snow height. Their default
582      is the standard parameter SEAICEadvScheme
583    o calc_gw:
584     - add cosFacU in zonal viscous flux (harmonic.visc.).
585     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
586       of tutorial_plume_on_slope.
587    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
588    o calc_gw: true flux-form, account for horizontal grid spacing.
589      update rotating_tank results, but not plume_on_slope (affected at
590      truncation level, 11 digits).
591    
592    checkpoint58l_post
593    o calc_gw:
594     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
595     - remove side-drag for now (need to fix it); update plume_on_slope results.
596     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
597    o commit code to make SST/SSS weights spatially variable
598      (based on either variable in-situ or variable initial T/S weights)
599    o pkg/ecco:
600      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
601        now based on horizontally varying weights wthetaLev, wsaltLev
602      * cost_averagesflags now returns year indices in addition to day, month
603      * sflux balance is performed on annual basis
604        (sflxumm, sfluxmm2, bal_sfluxmm)
605      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
606        including separate counting and multipliers
607    o pkg/rbcs
608      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
609    
610    checkpoint58k_post
611    o testreport:
612     - always build in dir. "build" (if not there, mkdir build instead of building
613       & running in input)
614     - run in dir run (if it exists), in build otherwise.
615     - call prepare_run (if input/prepare_run exists)
616     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
617    o pkg/exf modifications to interpolation and rotation routines for more
618       reasonable treatment of North Pole singularity: for tracers North Pole
619       value is set to northernmost zonal-mean value, for zonal velocity it is
620       set to zero, and for meridional velocity it is set to northernmost value.
621    o pkg/exf/exf_check_range.F
622     - add tile index to diagnostics and move stop statement to the very
623       end of the routine.
624    o pkg/diagnostics: (diagnostics_main_init.F)
625      define title of isomorphic variables according to the current config.
626    o pkg/thsice with pkg/seaice dynamics:
627    - fix domain of computation (interior only, required for exf) and do exchanges
628    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
629    o towards a standard way of dealing with multi-threading in MONITOR
630      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
631    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
632       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
633    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
634    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
635    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
636       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
637    o tracer advection:
638     - clean-up and simplify calc_common_factors.F
639     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
640       advection subroutine (but still not used within DST advection S/R)
641    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
642    
643    checkpoint58j_post
644    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
645      from file (collects calls previously in FORWARD_STEP)
646    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
647    o adjoint store dir. adjusted accordingly
648    o genmake2
649      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
650    
651    checkpoint58i_post
652    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
653      on wind stress (SEAICEstressFactor defaults to 1.)
654    o Total number of Timers is finite (<=40): comment out 2 non-essential one
655      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
656    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
657      on CS-grid: no longer loosing mass.
658    o exf & curvilinear-grid: no longer modify longitude xC & xG.
659    o pkg/ggl90: fix sloppy output and fix a bug
660    o pkg/seaice: added SEAICEuseEVPpickup parameter
661      - Set to false in order to start EVP solver with
662        non-EVP pickup files when using SEAICEuseEVP
663      - fix sign error in diffusion in seaice_calc_rhs
664    
665    checkpoint58h_post
666    * Modifications for bottom topography control
667      o replace hFacC by _hFacC at various places
668      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
669      o add non-self-adjoint cg2d_nsa
670      o update autodiff support routines
671      o re-initialise hfac after ctrl_depth_ini
672      o works for 5x5 box, doesnt work for global_ocean.90x40x15
673    * Adding verification for 5x5 box (4-layer) bottom topography control
674    
675    checkpoint58g_post
676    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
677       used for mean seasonal cycle, mean diurnal cycle); add an example
678       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
679    o pkg/ggl90:
680      - add parameter (minimum surface kinetic energy)
681      - fix bug (avoiding division by zero)
682    o couple pkg/thsice to pkg/seaice:
683      - modify advection in seaice to accomodate new scalar fields to be advected
684      - only muliDimAdection scheme work with seaice/thsice
685      - mapping of thsice-variables to seaice-variables, back and forth
686      - does not break the verification experiments, but does not give the
687        desired results either
688    o pkg/seaice
689      - make (default) second order advection a bit less confusing?
690    
691    checkpoint58f_post
692    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
693      to pkg/seaice):
694      - new routines thsice_map_exf and thsice_get_exf provide the interface
695      - add an additional formal parameter to thsice_solve4temp
696    o pkg/exf:
697      - add new fields wspeed, snowprecip (to be able to couple to thsice)
698      - correct Stefan-Boltzmann constant
699      - new parameter for longwave surface emittance
700      - separate some stuff from exf_bulkformulae into new routines  
701        exf_radiation, exf_wind
702      - add new parameters and constants: longwave emissivity for ocean, ice
703        and snow, evaporation parameters over ice
704      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
705        either wind from stress or stress from wind
706    o pkg/thSIce:
707    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
708    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
709       and THSICE_CALC_THICKN
710    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
711    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
712      to make debugging easier.
713    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
714    o pkg/bulk_force:
715      - clean-up comments and parameters ;
716      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
717    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
718      generate new output for test-experiment: aim.5l_cs.thSI
719    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
720      testreport accordingly
721    
722    checkpoint58e_post
723    o SEAICE_CGRID adjoint done
724    o R_STAR adjoint implemented.
725      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
726      * need to sort out init. of h0facc, etc.
727    o Make pkg/profile fully independent of ecco,cost, etc. stuff
728      to be able to use it in pure forward.
729    
730    checkpoint58d_post
731    o upgrade simple test-experiment to tutorial example:
732     step.1: duplicate the experiment and (step.2) will remove the old copy.
733      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
734      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
735      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
736      tutorial_global_oce_biogeo    <- copy of dic_example
737      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
738      tutorial_plume_on_slope       <- copy of plume_on_slope
739      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
740      tutorial_global_oce_optim     <- empty for now (David ?)
741      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
742     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
743    o correct a sign problem in cost_scat.F
744    o obcs and ptracers: fix boundary conditions for advections schemes
745      with larger stencil
746    o thsice adjoint: start
747    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
748      completeness
749    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
750      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
751    o ptracers adjoint:
752      * avoid extensive recomputatations
753      * fix missing re-init. of gptr (missed by TAF)
754    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
755      me to turn off the excessive output to STDOUT that this package produces
756    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
757      and add those terms in Vector-Invariant formulation.
758    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
759      if the control period (xx_hfluxperiod etc) is 0
760    o in profiles pkg, clean routines and fix details
761    o in ecco pkg, reading ssh data:
762      fix problem in case the model does not start at iter0=0
763    o fix mnc-pickup/restart for ptracers
764    o new package prifiles:
765      code to compute profile-based cost by Gael Forget
766      (modifs in ecco, ctrl, autodiff)
767    o Benign bug fix in initialization (spotted by M. Mazloff) of
768      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
769    
770    checkpoint58c_post
771    o adjoint: finish NLFS adjoint and provide reference output in
772      verification/global_ocean.90x40x15/results_ad_nlfs
773    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
774      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
775      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
776      with SEAICE_CGRID defined.
777    o move calendarDumps from "data" to "data.cal" and clean-up the code
778      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
779    o add useEXF & useCAL flags (for now, set in hard-coded way)
780    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
781      (were missing in NH mode, and wrong in quasihydrostatic mode).
782      waiting for Chris updated version of calc_gw to add those CALLs.
783    o fix bug in quasihydrostatic S/R ;
784      add a test for this option: global_ocean.90x40x15.qshyd
785    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
786      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
787    o add on/off flag useOffLine for package OFFLINE
788    o seaice:
789      - modify advection so that it works also on the C-grid
790      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
791        problem in multi-tile runs with C-grid
792      - add flags for clipping ice velocities and/or masking solver forcing
793      - fix drag (ocean on ice) formulation and a bug that caused noise in the
794        C-grid solver
795      - added a few comments to seaice_diffusion.F
796      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
797        are now exclusive)
798      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
799        required re-ordering the code a little:
800       + make DAIRN global variable (defined in SEAICE)
801       + move computation of the viscosities eta and zeta into a new separate
802         routine (because I need to recompute them in seaice_ocean_stress.F)
803    
804    checkpoint58b_post
805    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
806      update output.txt of exp. aim.5l_cs.thSI
807    o various mnc cleanups and improvements:
808      + shrink lookup tables by factor of ~4
809      + better error reporting when running out of lookup space
810      + able to handle longer path/file names (up to 500 chars)
811    o adjoint:
812      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
813      - TBD: "hidden" mom_vecinv recomp. in dynamics
814    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
815     (allow to differentiate between forcing components using new integer flags:
816      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
817     and add new flag to put Dissipation tendency out of Adams-Bashforth.
818    o ecco
819      - enable trend removal from SSH anomaly obs.
820    o adjoint
821      - a fix for PmEpR when #undef EXACT_CONSERV
822      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
823      - try to fix "hidden" recomp. in forward_step for NLFS
824        (NLFS seems broken sometimes after I checked it in)
825    o seaice:
826     - add c-grid version of the dynamic solver:
827       + three new routines that are the c-grid substitute lsr, dynsolver
828         and ostres
829       + put a few fields that were local to dynsolver into global common
830         blocks, so that I can move the computation of stresses etc into
831         seaice_lsr (saves coding but may break the adjoint).
832     - replace more hardwired parameters by runtime parameters
833     - add ice masks that mask the rhs of the implicit solvers where there
834       is no ice (commented out in seaice_dynsolver, because i am not sure
835       if this works properly), eventually this should replace the clipping
836       of ice velocities in seaice_dynsolver to +/-40cm/s.
837    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
838      include it only where its needed
839    o move balancing of fluxes before the call of external_forcing_surf
840    o seaice:
841      - correct units of turning angles (now they are really in degrees)
842      - move computation of GWATX/Y out of main routine into dynsolver
843      - initialize GWATX/Y in seaice_init
844    o Apply mask on Fresh-Water flux (needed for SSH forcing).
845      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
846    o seaice: add runtime flags for turning angles (default to zero)
847    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
848      and trend from exf forcing and ctrl control adjustments
849    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
850      (since checkpoint57x_post)
851    o change the default rotation period to 86164.s = the Earth rotation
852    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
853      and based on a reference stratification. Tested within hs94.cs-32x32x5.
854    o seaice advection: add code for choosing between the default (2nd order
855      central differences) and multiDim advection schemes provided by
856      pkg/generic_advdiff
857    o seaice:
858      - removed all references to SEAICE_GRID.h fields from
859        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
860        (cubed-sphere configuration will change a little)
861      - grid computations in seaice_init are obsolete now.
862      - cleaned up code a little so that is easier to read (hopefully).
863      - added new (better?) discretizations of default advection and diffusion
864        (turn on with SEAICEuseFluxForm)
865      - replace 1 in 3d global fields by kSurface in growth.F
866      
867    checkpoint58a_post
868    o seaice:
869      - bug fix in advect.F
870    o shelfice:
871      - separate shelfice load anomaly from pload (breaks with time
872        dependent forcing), => introduce constant field shelficeLoadAnomaly.
873        Its default is 0., but it may be computed more cleverly from (unknown)
874        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
875        done offline. A good approximation of the pressure load anomaly is
876        necessary to avoid large initial adjustment processes underneath
877        deep-reaching shelfice.
878      - small fix in ISOMIP shelfice_thermodynamics
879      - add more sophisticated thermodynamics of Hellmer (1989), this is
880        now the default
881      - give a few constants more intuitive names
882    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
883      if bulk formulae are used in long integration (especially EmPmR). Turn
884      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
885      if balancePrintMean, the imbalance that is substracted is printed to
886      STDOUT.
887    o fix bug (typo) in obcs_apply_eta.F
888    o add a new package shelfice which enables us to model the circulation
889      underneath shelf-ice with draughts of hundreds of meters.
890     - works
891     - to do: + include improved thermodynamics
892              + check whether kSurfC (from model/inc/SURFACE.h) can be used
893                instead of new field kTopC
894              + can we use topoFile, Ro_surf and existing code in ini_depth.F
895                instead of new field R_shelfIce and new code in ini_depth.F
896                and ini_mask_etc.F?
897              + adjust vertical mixing schemes?
898    o seaice pkg:
899     - add a cpp-flag to include a simple formula for a salinity dependent
900       freezing point of sea water at the surface
901     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
902       meridional stresses are now different (and hopefully correct)
903    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
904       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
905       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
906    o pkg/diagnostics: add options and parameters for regional-statistics
907       diagnostics ; define regions by reading a region-mask from a file
908       (might add other options later)
909    o pkg/bulk_force:
910     - add option and parameters to use AIM surface-flux formulae.
911     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
912       others forcing fields (defined in PARM05, parameter file "data") are loaded
913       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
914     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
915     - use the right EXCH call for uwind,vwind (to work on CS-grid).
916     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
917       and parameters (note: calcWindStress replaces .NOT.readwindstress).
918     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
919    
920    checkpoint58
921    o add "--embed-source" option to genmake2 which, when the supporting
922      tools can be compiled (as determined by genmake2) will turn on the
923      embed_files package which then embeds the entire MITgcm source code
924      (*.[fFhc] + Makefile) used for the build within the executable
925      - requested by CNH but off by default
926      - adds a paltry <9MB to the mitgcmuv executable in most cases
927      - only writes the output when useEMBEDSRC in eedata is true
928    o clean up 3-dim. relaxation codes:
929      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
930      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
931      * Thanks to Tom Haine for testing!
932    
933    checkpoint57z_post
934    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
935      affects output (@ truncation level) of exp. plume_on_slope ; updated.
936    o fix the pickup behavior for obcs in combination with ptracers
937    o fix a bug in ptracers_external_fields_load
938    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
939      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
940    o transfered surface NH pressure to eta field (if exactConserv).
941    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
942         and update lab_sea output.txt file.
943    o completing 3-dim. relaxation code: additional term
944         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
945      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
946      * At compile time, in "EXF_OPTIONS.h" set
947          #define  ALLOW_CLIMTEMP_RELAXATION
948          #define  ALLOW_CLIMSALT_RELAXATION
949      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
950          tauThetaClimRelax3Dim = 15552000.0,
951          tauSaltClimRelax3Dim  = 15552000.0,
952      * 3 cases:
953          1) Use a constant-in-time 3-dim. field
954          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
955          3) Real-time relax. to time-evolving prescribed field
956    o Adding Laplacian-type smoothness constraint on
957      initial and boundary (forcing) controls (ic, bc)
958      * enable at compile-time via
959        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
960      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
961      * Absolute scale somewhat unclear so far
962      * no area weighting was included since no other cost term does so far
963    
964    checkpoint57y_post
965    First step for a NLFS adjoint
966    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
967    o new init. routines for calc_r_star, calc_surf_dr
968    o still need to deal with ini_masks_etc
969    o testreport seemed happy
970    checkpoint57y_pre
971    
972    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
973    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
974    o add new offset feature to offline pkg (plus minor cleanup)
975    o cfc fixes for final year of integration
976    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
977      be in GCHEM_OPTIONS).
978    
979    checkpoint57x_post
980    o fix testreport Pb in multiple test experiment.
981    o cleanup our namelist syntax in verification:
982      - make it more F95 standards compliant (some work still needed)
983      - allows the vast majority of our tests to work with gfortran
984    o Non-Hydrostatic:
985     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
986     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
987    o Allow to apply AB on T,S rather than on AB(gT,gS):
988     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
989     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
990       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
991     - need a "clever" read_pickup to restart from the other AB formulation
992    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
993    o remove some unused variables (reduces number of compiler warnings)
994    o adjoint
995      * Disable useVariableViscosity for adjoint for time being
996        (there are a number of extensive recomputations)
997      * Initialize certain variables needed for adjoint
998    
999    checkpoint57w_post
1000    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1001                 fix the singleCpuIO RS version of MDSWRITEFIELD
1002       and add a WARNING if using globalFiles=T with multi-processors.
1003    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1004      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1005    o tracer advection scheme:
1006      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1007       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1008       was not very convenient).
1009      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1010       (further tests needed for the implicit DST & Flux-Limiter schemes).
1011    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1012      and sRef for convenience, handy, when you want to initialize
1013      ptracers in a large domain with a constant non-zero value. Also,
1014      untangle ptracers_init.F a little.
1015    
1016    checkpoint57v_post
1017    o change dome exp. to use variable viscosity in side-drag terms.
1018    o remove all the files from the cfc_offline test since they are now
1019      incorporated into tutorial_cfc_offline which has been producing
1020      identical results for a few days of testing
1021    o add new parameter: sideDragFactor to enable half-slip-side BC
1022      and change side-drag S/R to use viscosity from mom_calc_visc
1023      (can switch back by setting sideDragFactor=0.); affects results at
1024      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1025       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1026    o vorticity & strain are now computed without masking, to account for
1027      no-slip-side BC in variable viscosity calculation ; mask is applied
1028      anyway later on, before computing advection/coriolis terms.
1029    o modify exp4 to test new obcs support for reading from external files
1030      and for passive tracers
1031    o fix behavior of ptracers_monitor when monitor output is written to a
1032      netcdf-file; still not independent of monitor.F (writes in the same
1033      file).
1034    o change default value of tRef (put a uniform, meaningful value for ocean
1035      & atmos) and initialize sRef (was missing, as Martin mentioned).
1036    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1037      to be proportional to enstrophy dissipation length.  Thus,
1038       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1039      This is now consistent with Smagorinsky and with the manual.
1040    
1041    checkpoint57u_post
1042    o OBCS and PTRACERS: add open boundary support for passive tracers
1043      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1044        OB-values from file; this is not different from the way theta and salinity
1045        are treated
1046      - however, Orlanski-radiation conditions are not supported, and the model
1047        will stop if you use pTracers and Orlanski at the same time.
1048      - beefed up the rountine obcs_external_fields_load: now only those open
1049        boundary values are overwritten with values from files for which there
1050        are really files, otherwise the OB-fields remain untouched. This makes
1051        it possible to use different OBs at different ends of the domain (as
1052        with EXF)
1053    o reduce number of exch calls in shap_filt (s2).
1054    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1055      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1056    
1057    checkpoint57t_post
1058    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1059    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1060      same truncation, independent of the face number: affects affects several
1061      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1062    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1063      note that biharmonic viscosity + no-slip was not tested in any experiment.
1064    o fix bug in non-linear free-surf side-drag ; generate new output for
1065      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1066    o make mnc honor the writeBinaryPrec flag for most kinds of output
1067    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1068    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1069      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1070    o add brackets in multi-terms sum to get same truncation, independent of
1071      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1072      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1073    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1074      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1075      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1076      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1077      Suggested values of viscosity parameters found in mom_calc_visc.
1078      Many new viscosity diagnostics available.
1079    
1080    checkpoint57s_post
1081    o Add clearing-house for viscosity calculations, mom_calc_visc and
1082      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1083      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1084      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1085      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1086      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1087      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1088      ViscAhStrain and viscAhTension are now retired.
1089    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1090    o In response to JMC's bug report, genmake2 now ignores any soft-links
1091      that it finds in the *current* directory when searching for files.
1092      Soft-links found in any other source directories will still work as
1093      they did before.
1094    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1095      a C routine to unlimit the stack size
1096    o mnc-ify pkg/aim snapshot vars
1097    o mnc-ify pkg/land as requested by Daniel
1098    o various changes to mnc including:
1099      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1100      - output can now be grouped so that all files within a group
1101          change the ITER portion of their names in lock-step together
1102      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1103          and works with both EXCH1 and EXCH2 (but needs more testing)
1104      - writing works for all verification test cases w/ g77 on Linux
1105    
1106    checkpoint57r_post
1107    o make MNC variable initialization happen earlier
1108    o add diagnostics for (almost) each term of the momentum Eq.
1109    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1110    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1111    o remove MINIMAL_TAVE_OUTPUT option ;
1112      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1113    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1114      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1115    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1116    o add time-dependent SST, SSS control
1117    o cost terms in ecco/ modularized (new cost_generic.F)
1118    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1119    o new infrastructure for seaice model vs. obs misfits in seaice/
1120      * driver from the_main_loop.F is seaice_cost_driver.F
1121      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1122      * gradient check in Exp. 6a of natl_box_adjoint/
1123    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1124      (see README file)
1125    
1126    checkpoint57q_post
1127    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1128    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1129      - bug was reported by Jean-Michel and Ian Fenty
1130    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1131      update exp. cpl_aim+ocn output.
1132    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1133      Needed for high-res. runs with large global files
1134      to be able to limit tapelev size
1135    o Changed some tests for adjoint:
1136      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1137      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1138      * global_ocean.90x40x15/ back to default 3-level checkpointing
1139    o Modifications to enable scripted COMMON to MODULE conversion
1140      * verification/OpenAD/code/ has necessary scripts and description;
1141      * converts, compiles and runs successfully;
1142    
1143    checkpoint57p_post
1144    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1145    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1146      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1147    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1148    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1149      (was already the case for dissipation with mom_vecinv,
1150       and also the case for grad.PhiHyd when staggered-timeStep)
1151      This will allow to put dissipation out-off the AB time-stepping.
1152     Unfortunately, affects truncation error. Update output of exp. that "fails"
1153      (cg2d matching number) and leave the others for later: front_relax(10),
1154      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1155      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1156    
1157    checkpoint57o_post
1158    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1159      (2) its ready to be documented during the 20050801 DocFest
1160    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1161      for ideal_2D_oce and lab_sea on linux_ia32_g77
1162    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1163      in global1x1_tot/code_seaice_adj to access indices 32, 33
1164      (worth another tag)
1165    
1166    checkpoint57n_post
1167    o adding precip control xx_precip 32
1168    o adding swflux control xx_swflux 33
1169    o Replacing 10 forcing penalty cost routines by 1 generic.
1170    o Implementing partitioning in time-mean and variable adjustment
1171      for atmos. state.
1172    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1173    o in natl_box_adjoint:
1174      * updated exp 1 to 10
1175        (but does not have time-mean vs. variable split results yet)
1176    o updated global1x1/*_seaice_adj/
1177      to incorporate latest changes
1178    o enable useSingleCpuIO for mdsio vector routines
1179      (applies in particular to tapelev I/O)
1180    o removed inefficient K-loop in all active_file*control*.F
1181    
1182    checkpoint57m_post
1183    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1184      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1185    o pkg/exch2: filling of face-corner halo regions is optional
1186      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1187    
1188    checkpoint57l_post
1189     tag before updating tutorials (pre-release-2)
1190    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1191       for output and interpolation of input fields onto model grid)
1192    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1193       Affects results of exp. rotating_tank ; update output.txt.
1194    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1195          and taking the square quantity and/or using a fraction-weight field.
1196    o fix aim_diagnostics_init.F mate numbers.
1197    o add mnc output capability to diagnostics/diagstat and update
1198      our cvsignore files for the ACSII output generated
1199    
1200    checkpoint57k_post
1201    o lab_sea now uses diagnostics package and provides a suite of
1202      new EXF diagnostics output.
1203    
1204    checkpoint57j_post
1205    o exf
1206      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1207        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1208        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1209      * extended diagnostics output
1210        - now includes all EXF variables
1211        - hs, hl moved to common block
1212        - separate S/R for diagnostics, called after ctrl vector is added
1213        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1214        - EXFqnet contains true Qnet (i.e. includes qsw)
1215      * updated verif. lab_sea, global_with_exf
1216      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1217        to ensure that diagnostics sees a true EXFqnet
1218    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1219    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1220      several times with different frequencies.
1221    o mnc-ify the thsice package as requested by Daniel Enderton
1222      - the monitor--MNC output needs work
1223      - many attributes need to be added (most are currently blank)
1224    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1225      - many attributes need to be added (most are currently blank)
1226    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1227    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1228    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1229      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1230         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1231    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1232     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1233    
1234    checkpoint57i_post
1235    o Diagnostics package was changed: diagnostic allocation is now deactivated
1236      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1237    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1238      add 1rst Order upwind vertical Shear.
1239    o add a quick fix for A/B checkpointing in OFFLINE mode
1240    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1241      end-run around the C/Fortran linking horror in eesup/src/timers.F
1242    o added pkg/runclock: allows user to terminate run based on wall clock
1243    o added non-hydrostatic scaling parameter: nh_am2
1244    o pkg/my82: futile attempt to make results compiler-independent by adding
1245      some "_d 0", etc. no effect.
1246    o for mnc output, fill the 'T' coordinate var with myTime and create a
1247      separate 'iter' variable for iteration count
1248    o pkg/diagnostics:
1249      add new capability: output of Global/Regional & per-level statistics ;
1250      tested against monitor output (including land & thSIce) on various exp.
1251    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1252    
1253    checkpoint57h_done
1254      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1255      data.diagnostics, data.gchem, data.ptracers) is done.
1256    
1257    o pkg/diagnostics: prepare for Global/Regional statistics.
1258      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1259    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1260      and rename it: DIFFERENT_MULTIPLE
1261    
1262    checkpoint57h_post
1263    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1264    o pkg/diagnostics: change output frequency, now in seconds (instead
1265      of Nb of iterations). This requires to change data.diagnostics.
1266    checkpoint57h_pre
1267    
1268    o in mnc, let the user create the output dir if both mnc_outdir_date
1269      and mnc_outdir_num are false
1270    o add fflags() to pkg/diagnostics which allows one to specify, on a
1271      per-file basis, the file precision [default behavior is unchanged]
1272    o added diagnostics to pkg/kpp, including computation of mixed layer
1273      depth based on a temperature/density criterion
1274    o updated verification/natl_box to test the new pkg/kpp diagnostics
1275    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1276    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1277    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1278      not mnc -- this mistake was found by JMC and is now corrected
1279    
1280    checkpoint57g_post
1281    o add Adams-Bashforth 3rd Order time stepping:
1282      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1283      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1284    checkpoint57g_pre
1285    
1286    o make lambda[Theta,Salt]ClimRelax spatially varying
1287      (default remains spatially uniform constant based on tau)
1288    o added new control variables
1289      * init. uVel, vVel, etanN
1290      * lambda[Theta,Salt]ClimRelax
1291    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1292      (suggested by G. Forget)
1293    
1294    checkpoint57f_post
1295    o add parameter "baseTime" = model base time = time at iteration zero
1296      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1297      account for baseTime shift
1298    o move Coriolis arrays from PARAMS.h to GRID.h
1299    checkpoint57f_pre
1300    
1301    o mnc-ifying the seaice package
1302    o introduced an alternative length scale calculation for use in the limiting
1303      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1304    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1305    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1306      as well as grad(vort3).  Made it compatible with both approximate form
1307      for the cubed sphere and full form of these gradients.  Added flag
1308      useFullLeith to select between approximate and full form.  
1309    o add "d0" in getcon.F to reduce differences between compilers/platforms
1310      update output.txt of exp. fizhi-gridalt-hs
1311    o change port_rand funtion to allow to set the seed.
1312    o fix obscure MNC bug involving conversion between reals and integers
1313      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1314        new version is now more standards-compliant
1315    o adjoint-related modifications
1316      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1317      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1318      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1319    
1320    checkpoint57e_post
1321    o Adding eddy stress controls a la Ferreira et al.
1322    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1323    
1324    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1325      update output.txt of exp. fizhi-gridalt-hs
1326    o add more "Z" dimensions and associated coordinate vars to MNC
1327    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1328    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1329      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1330      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1331      months and years.  Requires pkg/cal.
1332    o diagnostics: add pickup functionality
1333      - off by default for backwards compatibility
1334      - current version only uses MDSIO -- MNC will be added
1335    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1336    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1337    
1338    checkpoint57d_post
1339    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1340    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1341      output from the diagnostics package
1342    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1343    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1344      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1345    o add coordinate variables to the MNC output from the diagnostics package
1346    o change MNC-flags default value: true when useMNC=TRUE
1347    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1348      the ability (off by default) to read the grid information using MNC
1349    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1350    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1351    o do snap-shot diagnostics at the middle of the time-interval (instead of
1352      at the end).
1353    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1354      new test for AIM with thSIce + slab-ocean
1355    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1356    o move state variable diagnostics to the beginning of the time step ;
1357      (note: still needs some work specially for snap-shot diagnostics)
1358      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1359    
1360    checkpoint57c_post
1361    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1362    o generate new output.txt files on faulks with g77 & the new -ieee option
1363    checkpoint57c_pre
1364    
1365    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1366      update output.txt of exp. global_ocean.90x40x15
1367    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1368      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1369    o add saltFlux(+File) forcing capability with periodicExternalForcing
1370    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1371    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1372    o improvements for the MNC output from DIAGNOSTICS:
1373      - correct handling of the unlimitied dimension
1374      - all dims now have associated coordinate variables
1375      - variables located at U, V, and Corner ("Z") points are now written
1376        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1377        *all* data points are output
1378    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1379    o added pkg/seaice/seaice_monitor.F
1380    o mdsio_readfield.F can now read files visible only to master MPI process.
1381    o pkg/seaice: some test code for ice-modified ocean stress
1382    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1383      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1384      spurious negative numbers for precipitation and humidity.  Will cause
1385      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1386    o pkg/ctrl/
1387      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1388        May be enabled via doPackDiag
1389      *  introduce z-scaling of
1390         + gradient (doZscalePack) and
1391         + control (doZscaleUnpack)
1392    o pkg/mdsio/
1393      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1394      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1395    
1396    checkpoint57b_post
1397    o simplify options in diagnostics_fill arguments (remove weird combinations)
1398    o fix MNC coordinate variables so that they now contain per-face index
1399      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1400      general, EXCH2 grids are only aligned to a "local" coordinate system
1401    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1402    o Implement instantaneous output within pkg diagnostics:
1403      setting a negative frequency in data.diagnostics produces
1404     "snap-shot" output (as opposed to time-average if freq > 0)
1405    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1406      NOTE: change ptracer diagnostics name: use 2 characters to work with
1407            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1408    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1409      becomes the coordinate variable for the 'T' dimension
1410    o add CF-style coordinate variables to MNC
1411      - just a first cut:  numbers are meaningless on the cubesphere and
1412        missing along the T axis but otherwise it works!
1413    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1414    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1415    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1416      this is based directly on what the model compute, so that the content of
1417      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1418    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1419    o clean up build options files for SunOS, in particular
1420      - remove -traditional from xmakedepend
1421      - change -xarch=v9 to -xarch=native for f77
1422      - restore use of make (not gmake)
1423      - add CC=gcc if using g77
1424    o changes per discussion of AM, JMC, & EH3 today:
1425      - move redundant "grid" variables out of "state" -- in preparation of
1426        creating proper CF-style coordinate variables and in recognition
1427        that any/all grid variables can be easily copied (eg. w/NCO) from
1428        the grid files into any of the other NetCDF files
1429      - *always* output grid variables with MDSIO (this will eventually be
1430        changed)
1431      - output MNC grid file if useMNC is true
1432    o every instance of _END_MASTER() has been found and replaced with
1433      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1434      preprocessors
1435    o re-arrange diagnostics pkg initialisation:
1436     - allow each package to extend the available diagnostics list
1437     - add some checking and fix small problems (multi-threaded, ...)
1438     - new S/R diagnostics_fill (replace fill_diagnostics):
1439       look through the short list of active diag. (instead of the long list)
1440       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1441    
1442    checkpoint57a_post
1443    o this set of changes restores TAMC compatibility
1444      tested for global_ocean.90x40x15 adjoint on trough
1445      (what a pain)
1446    
1447    checkpoint57a_pre
1448    o some modifs in tools/build_options for sunos
1449    o call ctrl_pack for ctrl at end for optimcycle=0
1450    
1451    checkpoint57
1452    o add horizontal bi-harmonic viscosity for vertical velocity
1453      - new parameter viscA4W (defaults to viscA4)
1454      - affects only non-hydrostatic code
1455      - to be done: no-slip lateral boundary conditions
1456    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1457    o implement Implicit Vertical advection for pTracers
1458    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1459      (implemented also for implicit vertical diffusion & advection)
1460    o OBCS: extend application of tracer open boundary conditions
1461      to a strip beyond the boundary of width Olx/Oly
1462    o add call monitor to TAF set of required calls (flow directives)
1463      and include in natl_box_adjoint
1464    o untangle a few ifdefs related to cost, ctrl, autodiff
1465      untangel a few ALLOW_ECCO_OPTIMIZATION
1466    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1467      (theta2, salt2 in ecco_cost_weights)
1468    
1469    checkpoint56c_post
1470    o OBCS as control variables
1471      - update ctrl_ad_diff.list, obcs_ad_diff.list
1472      - remove balance of obcs controls from default
1473      - fix index bug nobcs in ctrl_init
1474      - fix dummy fields filen in ctrl_pack
1475      - add dummy weights for obcs
1476    o lsopt: comment out fort.94 output
1477    o optim:
1478      - remove unnecessary header files
1479      - adjusted namelists
1480      - add xerbla.F to Makefile
1481    o exf:
1482      - multiple modifications of exf_check_range
1483      - unit change in exf_init_runoff from [m/year] to [m/s]
1484    o mdsio:
1485      - i/o-vector change debugLevel from debLevA to debLevB
1486    
1487    checkpoint56b_post
1488    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1489      is called from DO_THE_MODEL_IO
1490      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1491      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1492      - clean up PTRACERS_WRITE_TIMEAVE a little
1493    o add another verification experiment that tests both the cfc-pkg and
1494      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1495      reactive tendencies treated inline with regular timestepping
1496    o testreport previously did a lousy job of comparing small numbers, so
1497      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1498      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1499      testreport.
1500    o ptracers_monitor: bug fix for MPI
1501    
1502    checkpoint56a_post
1503    o GCHEM: finish reorganizating the package
1504      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1505        (introduces another 3D-array for each passive tracer, but only if
1506        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1507        gchemTendency is not needed because the timestep is done separately)
1508      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1509      - GCHEM is now---more or less cleanly---separate from PTRACERS
1510      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1511        so clear to me how that should be done in a general way.
1512    o CFC: improve formatting of output in CFC_ATMOS
1513    o PTRACERS:
1514      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1515        that ALL experiments with ptracers enable can be checked. This makes
1516        GCHEM_MONITOR obsolete.
1517      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1518        monitorFreq
1519      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1520    o add PTRACERS (PTR0[1-5]) to testreport output
1521    o exf_check_range:
1522      * default changed to .TRUE.
1523      * will check values for niter0 if debLevA, every timestep if debLevB
1524      * STOP in exf_check_range if 'out of range'
1525      * range chosen generous to allow for potential extema
1526      TBD: a version with stricter range
1527           permitted range would be runtime parameters
1528    o GMredi:
1529      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1530      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1531      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1532    o GCHEM:
1533      - move call to GCHEM_FORCING_SEP, so that it is now called before
1534        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1535      - introduced a useGCHEM runtime flag and applied it everywhere.
1536      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1537        this flag is now only visible within GCHEM-pkg routines.
1538      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1539        be replaced by a 3D array that is computed before thermodynamics; for
1540        this, the tracer ID iTracer had to be included into the parameter list
1541        of ptracers_forcing
1542      - set up forward_step to call gchem_forcing, that will replace
1543        gchem_forcing_int in ptracers_forcing
1544      - cleaning up
1545    o small cleaning of exch2: remove files that are also in eesupp/src
1546    
1547    checkpoint56
1548    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1549    o mnc: cleanup "full" files--fixes out-of-memory problem
1550    o ECCO-GODAE
1551      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1552      * fully merged and updated from SIO code
1553        windstress sign change affects
1554        - exf_inscal_[u/v]stress
1555        - sign of xx_tau[u/v] adjustments
1556        - signs in cost_scat
1557      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1558      * natl_box_adjoint updated and compressed
1559      * 2-level checkpoint switch added
1560        (tested in EXP. 1 of natl_box_adjoint)
1561      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1562    o SVD
1563      * first complete, non-hacked version for SVD calculations
1564      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1565        performed via direct access files admtlm_vector.it????
1566        (via ctrl_[un]pack)
1567      * optimcycle is used for ARPACK iteration counter
1568        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1569      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1570        and add linear transforms where necessary
1571      * controls are initial/final SST, SSS (can be extended; need to check
1572        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1573    o mdsio: filename info to both stderr, stdout
1574    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1575      from sign change
1576    
1577    checkpoint55j_post
1578    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1579      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1580    o add consistent build directories and .cvsignore files to verification
1581    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1582    o make all subroutines 30 or less characters in length for certain older
1583      compilers to work (a thorough search only turns up two routines in
1584      pkg/ptracers)
1585    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1586      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1587    
1588    checkpoint55i_post
1589    o change arrays for total vertical diffusivity (2.D if explicit,
1590      3.D if implicit) ; each ptracer uses its own background value.
1591    o added mnc/NetCDF output capability to ocn_compon_interf
1592      - added bits to verification/cpl_aim+ocn so that it can run on
1593        ITRDA and other clusters without the mpirun "-wd" option
1594    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1595      configuration
1596    o give MNC the ability to create additional files rather than
1597      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1598      - the default is just less than 2GB which is a practical limit
1599        on many systems
1600    o Compute the non-local term using either KPP vertical diffusivity (=default)
1601       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1602    
1603    checkpoint55h_post
1604    o add verification test "vermix"
1605    o remove all the *_ioinc flags and replace with the single global
1606      outputTypesInclusive flag
1607    o allow to set a vertical profile of vertical diffusivity for T & S
1608    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1609    o useMNC moved from data.mnc to data.pkg
1610    
1611    checkpoint55g_post
1612    o Renaming carbon AD experiments to comply with testreport conventions
1613    o Updating adjoint of Held-Suarez hs94.1x64x5
1614    o Fixing directives for non-ECCO forward_step, after ECCO directives
1615      have been fixed to avoid recomp. of do_oceanic_phys
1616      Works well for global_ocean.90x40x15,
1617      but recomp. issue remains for carbon
1618    o Updating adjoint output for natl_box_adjoint after
1619      pkg/ecco has been modified (see taga c55d_post)
1620    
1621    checkpoint55f_post
1622    o rename to timeave_init_fixed
1623    
1624    checkpoint55e_post
1625    o some delicate re-shuffle of store directives to avoid one
1626      extra call of do_oceanic_physics
1627      affects ecco_the_main_loop.F, do_oceanic_physics.F
1628      checkpoint_lev1_directives.h
1629    o NB: this may break global_ocean adjoint temporarily,
1630      but it is clear how to fix it. Will do later, need this now.
1631    
1632    checkpoint55d_post
1633    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1634    o ecco_cost_weights is modified to 1x1 runs
1635    o modifs to allow observations to be read in as
1636      single file or yearly files
1637    o enable to read exf forcing fields as either
1638      single file or yearly files (flag useExfYearlyFields)
1639    checkpoint55d_pre
1640    
1641    o switch between 2-level and 3-level checkpointing
1642    o add ability of MNC to write local and "partial" (eg. 2D slices where
1643      the full 3D field is never actually stored) arrays to NetCDF files
1644      with the correct (that is, the complete multi-dimensional) set of
1645      array indicies
1646      - used in mom_vecinv() to write the diagFreq output
1647      - tested (demonstrated) in verification/aim.5l_cs
1648    o further mnc-ification
1649      - add verification/lab_sea to the list with mnc setups
1650      - fix undefined mnc v-names in cd_code
1651      - add kpp to mnc output (both snapshot and timeave)
1652    o non-hydrostatic code
1653      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1654        in calc_gw.F
1655      - defaults to viscAh
1656      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1657        friction or Leith) in non-hydrostatic mode, as long as there is
1658        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1659    o pkg/cost
1660      extend simple cost functions to treat time mean quantities
1661      (T,U,V) via cost_accumulate_state from cost_tile
1662    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1663        be 2 times larger than the minimum size the advection scheme requires.
1664        now get a perfect conservation of salt in advect_cs test-exp (updated)
1665    o GGL90 (Gaspar's TKE mixed layer)
1666      - add horizontal diffusion of TKE, requires exchanges in
1667        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1668        default. In OPA there is no horizontal diffusion of TKE but the
1669        mixing coefficients are computed from a horizontal average of TKE of
1670        6 points or so. I think that diffusion has a little more physical
1671        justification.
1672      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1673        was in vain)
1674      - mask tke-variable in ggl90_init
1675    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1676    o fix biharmonic diffusion on CS-grid.
1677    o more obcs stuff
1678      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1679        for reading boundary values. This routine is called from
1680        obcs_prescribe_read
1681      - updated obcs_check
1682      - changed sponge layer relaxation parameter units for days to seconds
1683      - turned off sponge layer by default
1684      - changed argument list of OBCS_CALC to myTime+deltaTclock
1685      - fixed about 35 bugs in obcs_external_fields_load
1686    
1687    checkpoint55c_post
1688    o obcs stuff
1689      - new runtime flags useOBCSprescribe, useOBCSbalance
1690      - re-arranged obcs_calc
1691      - moved exf_getobcs to obcs_prescibe_read
1692        obcs_prescibe_read is called after ORLANSKI stuff
1693        and independent of it (executable can contain all).
1694      - updated obcs_check
1695      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1696        These may be necessary only if tangential velocities are
1697        prescribed at OB, not sure, needs testing.
1698    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1699      which simplifies the calls and passes the ifc check-bounds test
1700    
1701    checkpoint55b_post
1702    o add a 2D scalar, Z location, exchange_2 routine.
1703    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1704      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1705      affects advect_cs results (for the wrong reason): update output.txt
1706    o use a more standard discretization for biharmonic viscosity ;
1707     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1708      affects results of dome set-up: update output.txt
1709    o fix gad_advection.F (CubedSphere part), back to version 1.23
1710    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1711    
1712    checkpoint55a_post
1713    o merged code to
1714      * prescribe/read time-dependent open boundaries
1715        (works in conjunction with exf, cal)
1716      * sponge layer code for open boundaries
1717      * each boundary N/S/E/W now has its own CPP option
1718        (healthy for the adjoint)
1719    
1720    checkpoint55
1721    o up-to-date adjoint of previous breaks
1722      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1723      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1724      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1725      - carbon: * remove tr1-related adjoint verification
1726                * add ptracer as control variable
1727    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1728      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1729    
1730    checkpoint54f_post
1731    o in verification/carbin/ remove experiment related to
1732      ALLOW_PASSIVE_TRACER (array tr1 etc)
1733      code_ad/ input_ad/ results_ad
1734    
1735    o add two new packages
1736      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1737        + subject to optimization (memory)
1738      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1739        + subject to reordering (many GOTOs in the original code)
1740        + so far opps is called for every (i,j) point, and then operates in
1741          the vertical; one may want to reorder the scheme in order operate in
1742          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1743          fields)
1744    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1745      - all verification tests compile and run with linux_ia32_g77
1746      - defaults are compatible with current input files--nothing
1747        should change if you were not previously using MNC
1748      - MNC output has been added in numerous places (eg. timeave)
1749        but there are still a few writes not yet do-able with MNC
1750        (this is in progress)
1751      - flags now allow for either/or/both use of MDSIO and MNC and
1752        documentation will soon follow
1753      - numerous small formatting cleanups for ProTeX
1754    o add version info (via BUILD_INFO.h) to MNC and stdout
1755    
1756    checkpoint54e_post
1757    o add two new packages
1758      - pp81 (Packanowski and Philander, 1981), Richardson number and
1759        stratification dependent mixing
1760      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1761      - these scheme operate in a similar manner as KPP (without ghat, of
1762        course), however there is only one diffusivity that is used for both
1763        temperature and salinity (and passive tracers)ç
1764    o add offline package
1765    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1766      provided by Stephanie Dutkiewicz
1767    o genmake2: add ability to search for C compilers and cleanup test output
1768      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1769    
1770    checkpoint54d_post
1771    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1772    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1773      leading to additional shift by 5 days each year of integration
1774       (i.e. leading to considerable offset over the years)
1775    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1776    o start with no AB and no initial filtering (staggerTimeStep):
1777      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1778    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1779      (external loading & cpl import/export stay in forward_step.F)
1780    o update coupling interface to work with new staggerTimeStep
1781    o change MDSIO ptracers_pickup.
1782    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1783    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1784    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1785    
1786    checkpoint54c_post
1787    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1788      this affects (truncation error) output.txt of test-exp:
1789       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1790    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1791    o change Qnet to always be the net heat flux, (+upward).
1792      affects (truncation error) output of natl_box exp.: updated
1793    o define the max number of passive tracers in PTRACERS_SIZE.h
1794    o start to test mnc routinely in exp0
1795    o add sea-ice loading (sIceLoad) as a new forcing field.
1796    
1797    checkpoint54b_post
1798    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1799       impressive on Altix and Opteron systems)
1800    o diagnostics can now write NetCDF files through the mnc package
1801    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1802    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1803    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1804      affects (truncation error) output of lab_sea & natl_box exp.: updated
1805    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1806    
1807    checkpoint54a_post
1808    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1809    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1810    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1811    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1812      + internal_wave (shift in writing cg2d_ini_res)
1813    checkpoint54a_pre
1814    
1815    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1816      - modified verification/lab_sea and natl_box_adjoint accordingly
1817    
1818    checkpoint54
1819    checkpoint53g_post
1820    o prepare splitting of thermodynamics: store convect.counter in common block
1821    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1822      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1823    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1824    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1825    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1826    o restore adjointability
1827    
1828    checkpoint53f_post
1829    o modifications that affect AIM experiment results (update output.txt):
1830      - no advection of S at top interface Nr (pkg/generic_advdiff)
1831      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1832    o AIM pkg:
1833      - include stability function into surf.Flux derivative relative to Tsurf
1834      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1835    
1836    checkpoint53e_post
1837    o merged cylindrical coord configuration
1838    o added rotating_tank experiment
1839    checkpoint53e_pre
1840    
1841    checkpoint53d_post
1842    o faulks upgraded: re-generate output.txt that have changed:
1843       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1844    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1845    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1846    o added Sadourny discretization of Coriolis
1847      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1848      - re-enabled use of omega3 (useAbsVorticity)
1849    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1850      vector-invariant equations
1851      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1852    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1853      hopefully without new bugs
1854      - still to do: biharmonic friction for non-hydrostatic w
1855    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1856    o regenerated output for global_ocean_ebm (using -ieee)
1857    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1858      of mom_common/
1859      - simple re-arrangement of instructions within computing loop
1860    checkpoint53d_pre
1861    
1862    checkpoint53c_post
1863    o new version of coupler for AIM+thSIce and Ocean models
1864     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1865     - land: change Evaporation of snow
1866     - aim with thSIce: fix bug in snow-precip.
1867    o changes to calc_gw.F
1868     - bug fix for w^2 term near the bottom boundary
1869     - (hopefully) improve the lateral slip boundary condtions for use with
1870        partial/looped cells
1871      - because the bug fix changes two verification experiments anyway (exp5
1872        and plume on slope), change the lateral boundary condition from half slip
1873        to the value of no_slip_sides
1874    o ebm package wasnt quite up to the parallel task. Fixed that.
1875    o Adjoint of EBM package + verification
1876      * TLM OK
1877      * ADM not sufficient accuracy yet (needs further testing)
1878    
1879    checkpoint53b_post
1880    o Commiting new energy balance model to repository
1881      * package is pkg/ebm
1882      * verif. is verification/global_ocean_ebm
1883      * references are in ebm_driver.F
1884    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1885    C        Global thermohaline circulation. Part I:
1886    C        Sensitivity to atmospheric moisture transport.
1887    C        J. Climate 12(1), 71-82
1888    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1889    C        Global thermohaline circulation. Part II:
1890    C        Sensitivity with interactive transport.
1891    C        J. Climate 12(1), 83-91
1892    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1893    C        Destabilization of the thermohaline circulation
1894    C        by atmospheric eddy transports.
1895    C        J. Climate 7(12), 1870-1882
1896    o Will need long integration testing.
1897    checkpoint53b_pre
1898    
1899    o created pkg/mom_common in preparation for variable viscosity code
1900    o renamed and split ini_mnc_io
1901    o pkg/land: only liquid water can diffuse or run-off
1902    o AIM using land: soil wetness availability account for snow
1903    o added printMapIncludesZeros to EEPARMS namelist
1904    
1905    checkpoint53a_post
1906    o restore TAMC compatiility for exf_constants.h
1907      (no usage of _d in .h)
1908    o Additional storing in KPP in an attempt to fix
1909      TAMC problem with adjoint of KPP code.
1910      (no success...)
1911      Identical code works fine with TAF.
1912    o Fixed verification/natl_box_adjoint experiments.
1913      Initial conditions for Experiments 4 and 5 are now
1914      set to "SEAICE_initialHEFF=0", which is more reasonable,
1915      and hence gives results closer to that of Experiment 2.
1916      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1917    
1918    checkpoint53
1919    o stable checkpoint with up to date adjoint
1920      TLM tests only run for 1st grdchk at the moment. Its unclear if
1921      this is a code problem or a problem with resetting code for g_
1922      variables that is being autogenerated wrong.
1923      Otherwise:
1924       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1925       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1926         are both still in chaos following their security messes.
1927    
1928    checkpoint52n_post
1929    o various build (mostly genmake2) changes including:
1930      - ability to build/run more easily within Cygwin and MacOS X
1931      - more complicated Makefiles with a stronger dependence on Gnu Make
1932    o pkg/seaice modifications
1933      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1934        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1935        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1936      - changed proxy for geostrophic velocity and updated
1937        verification/lab_sea/results/* accordingly
1938      - removed ADI dynamic solver from pkg/seaice
1939      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1940        they caused a segmentation fault under certain circumstances
1941      - removed unused field WATR
1942    o bug fix in exf-package:
1943      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1944         now reflect that.
1945    o small fixes in the cal-package:
1946      - set reference date to first of January for the 'model'-calendar
1947      - failing of cal_CheckDate in cal_FullDate now actually results in a
1948        warning
1949    o small modifications in exf-package to increase flexibility:
1950      - change climtempfreeze from a constant to a runtime parameter that
1951        is specified in data.exf_clim (default = -1.9)
1952      - introduce runtime parameter windstressmax (default = 2.0) that is
1953        specified in data.exf
1954    o fix in pkg/thsice:
1955      - update Evap (Tsf changes) to be consistent with Latent heat flux
1956      - maintain snow precipitation unchanged (even if Tsf >=0).
1957     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1958    
1959    checkpoint52m_post
1960    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1961      this does not change any of the results, because myIter=0 in swfrac always
1962      lead to jwtype=2 (the default anyway), but the call makes little sense
1963      as a default
1964    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1965    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1966      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1967    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1968    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1969    o extending useSingleCpuIO option to work with new exch2 I/O format
1970      - old-style, missing-tile I/O is still accessible by defining CPP
1971        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1972    o monitor package can write to NetCDF files and/or STDOUT
1973    o fix re-definition bug in MNC_GRID_INIT_ALL()
1974    o doc/api_reference added
1975      - a framework for building an API Reference Manual using all
1976        the "protex" comments embedded in the code
1977      - see pkg/generic_advdiff, pkg/mnc for examples
1978    o MNC:
1979      - make myThid the last argument for all subroutines
1980      - new default for the grid files: NO halos
1981      - add useMNC and other run-time flags
1982      - separate per-file-group handling of the unlimited dimension
1983      - early initialization of MNC w/ flags read at the eeboot stage
1984        and lookup tables set in initialize_fixed
1985      - write all MNC output to a freshly-created directory
1986    o thermodynamics sea-ice (thsice) is now tested with testreport.
1987    o test exp. advect_cs: use the standard cs32 grid ; update output.
1988    o Added functionality to grdchk:
1989      pick global i,j,k position (or nearest wet) where to perform check.
1990    
1991    checkpoint52l_post
1992    o new land formulation:
1993      a) use ground enthalpy as prognostic variable to ensure exact
1994         energy conservation.
1995      b) account for water temperature and for latent heat of freezing
1996         in all processes (rain, run-off, ground storage)
1997      c) compute surface and ground temperature implicitly.
1998    o aim_v23 modification for new land model:
1999      a) Treat separately land / ocean / sea-ice surface fluxes
2000         to allow implicit computation of land & sea-ice surface temp.
2001      b) add snow precipitation.
2002    checkpoint52l_pre
2003    
2004    o fix problem (when 1 tile is empty) in min/max monitor.
2005    o fix bug in timeAve (u,vZetatave in common block)
2006    o no restoring terms under ice for pkg/seaice
2007    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
2008    o bug fix for pkg/seaice pickups
2009    o change MNC call locations and add coordinate attributes
2010    o mask vorticity at the corner ; affects global_ocean.cs output
2011    o fix ini_curvilinear_grid ; test CS experiments with mpi
2012    o aim.5l_cs: modify sea-ice fraction input file ; update output
2013    o exf: Adding simple range check routine for exf fields after read
2014    
2015    checkpoint52k_post
2016    o removed top-level directory "diags"
2017      - we migrated these functions to pkg/timeave a long time ago
2018    o fixed bug introduced in pkg/monitor
2019    o accuracy ctrlprec = 32 insuffient for gradient checks using
2020      averaged fields (I/O via cost_averages)
2021      -> use ctrl.h in active_file*.F to control I/O precision.
2022    o paramter list of CALL ADTHE_MAIN_LOOP
2023    o added initial do_the_model_io to ecco
2024    o set all ...Freq to zero after cost_final
2025      taveFreq, dumpFreq, pChkptFreq
2026    o MAIN and ECCO differentiability restored
2027    
2028    checkpoint52j_post
2029    o fix nchklev in tamc.h for global_ocean...
2030    o Bringing flow and store directives up-to-date
2031    o Really weird thing!
2032      call do_the_model_io from the_main_loop with parameters
2033      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
2034      TAF places a faulty re-call of initialise_varia
2035      after cost_final call which should not be there!
2036    checkpoint52j_pre
2037    
2038    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
2039      error messages
2040    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
2041    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
2042      debug output
2043    o modfied mdsio_writefield.F to handle non-global files under exch2
2044    o update AIM Cubed-Sphere exp (aim.5l_cs):
2045      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
2046    o update AIM Equatorial Channel exp:
2047      use standard aim_v23 pkg and change the SST fields to be more realistic.
2048    o globalFile now works with exch2
2049    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
2050      mon_vort3.F to make exch2 friendly with >1 tile per cube face
2051    o limit timeave output for hi-res integrations
2052    
2053    checkpoint52i_post
2054    o removed CPP_EEOPTIONS.h from verification/*/code
2055    o updated the tiling for global_ocean_pressure
2056    checkpoint52i_pre
2057    
2058    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
2059      the old pkg/aim).
2060    
2061    checkpoint52h_pre
2062    o shortened offending lines in exch2_send_rx?.template
2063    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
2064    o genmake2: add build & execute test for NetCDF code
2065    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
2066      old grid files, moved CPP_EEMACROS.h to pkg/exch2
2067    o added useSingleCPUIO flag to monitor.F and mon_out.F
2068    o added temporary hack for sea-ice dynamics on the cube:
2069      metric terms are ignored and it is assumed that
2070      there is no sea-ice on cube faces 1, 2, 4, and 5.
2071    
2072    checkpoint52f_post
2073    o added exch2 cube routines to pkg/exch2
2074    o modified hs94.cs-32x32x5 to use it
2075    o added new grid files to hs94.cs-32x32x5
2076    checkpoint52f_pre
2077    
2078    checkpoint52e_post
2079    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
2080      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
2081    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
2082      to work with implicit vertical advection and AB ;
2083    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
2084    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
2085     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
2086    checkpoint52e_pre
2087    
2088    o fix bug in impldiff when Nr=1 or Nr=2.
2089    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
2090    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
2091    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
2092      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
2093    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
2094    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
2095    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
2096    
2097    checkpoint52d_post
2098    o re-tiled many expts to allow comparison in multi-processor mode
2099      - updated output accordingly
2100      - changed hs94.128x64x5 to use intial T from file rather than use the
2101        random number generator
2102    o add infrastructure in model routines for fizhi and gridalt packages
2103    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
2104    o changes to permit hi-res, cubed-sphere, configuration
2105      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
2106      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
2107      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
2108        of surface winds for the cube
2109      (A verification experiment, based on global_ocean.cs32x15, but with
2110       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
2111       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
2112       complete with example surface forcing files and matlab scripts to look
2113       at the output and compare it with that of global_ocean.cs32x15.)
2114    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
2115       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
2116       to conform to the common rule.
2117    o check-in the first version of the coupler + interfaces for multi-components
2118       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
2119       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
2120       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
2121       - ocean and atmos. share the same horizontal grid (no interpolation).
2122       - exchanges between component and coupler is done in forward_step
2123    o new verification experiment, cpl_aim+ocn:
2124       coupled ocean - AIM atmosphere on cs32 grid.
2125    
2126    checkpoint52d_pre
2127    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
2128    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
2129    
2130    checkpoint52c_post
2131    o Fixing OPTIONS files for use of exf:
2132      - ALLOW_ECCO not needed
2133      - ECCO_CPPOPTIONS.h should not be included from
2134        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
2135        as has been the case in the past
2136      - All cal/exf related options are currently set in
2137        single header file. Should remain so until we
2138        agree on a consistent new policy.
2139    o Removed all CPP options for cal package.
2140      cal has no more CPP options.
2141    o modified STOREs in GAD_ADVECTION
2142    o corrected key comp. for passkey
2143    
2144    checkpoint52b_post
2145    o new version: "thsice" of thermodynamic sea-ice pkg:
2146     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
2147     - modify fluxes but do not change theta directly;
2148     - light cleaning of bulk_force pkg (still needed with thsice).
2149     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
2150       + output_thsice.txt to test thsice & bulk_force pkgs.
2151    o put back grid & coriolis monitor output.
2152    checkpoint52b_pre
2153

2157      (need info on NUMBER_OF_PTRACERS)
2158    o missing PTRACERS headers in some routines
2159    o default tamc.h in pkg/autodiff supposed to crash
2160      to ensure proper customization
2161    
2162    checkpoint52a_post
2163    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
2164      - moved surfaceTendencyTice from pkg/seaice to main code
2165      - subroutine FREEZE_SURFACE now limits only surface temperature
2166        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
2167        => new output.txt for global_ocean.cs32x15 & global_with_exf
2168      - keep the old version of FREEZE for backward compatibility;
2169        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

2181    o after testing adjoints of checkpoint51u_post
2182    
2183    checkpoint51u_post
2184    o this is the post-merge tag of the ecco-branch
2185      (needs another clean checkout and re-testing)
2186    o various natl_box_adjoint configs and results
2187      but no input fields

2196    o in ctrl/ cleaned some cross-dependencies and updated CPP options
2197    
2198    checkpoint51t_post
2199    o this is the pre-merge tag of the ecco-branch
2200    
2201    checkpoint51s_post
2202    o cleanup: removed various obsolete #define-s
2203    o pkg/grdchk
2204      - renamed 'ph-grd 3' to 'grad-res'
2205      - merged from ecco-branch
2206        (remaining bug fixes for obcs gradient checks)
2207      - additional high-precision output for testreport
2208        (grep for 'precision_grdchk_result')
2209

2211    o cleaned up or removed CPP_OPTIONS.h files
2212    o updated results for some of the tests to reflect the new
2213      optfiles (-ieee: -O0 instead of -O3)
2214    
2215    checkpoint51q_post
2216    o cd_code:
2217      - moved cd_scheme.F -> cd_code_scheme.F

2229    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
2230    
2231    checkpoint51p_post
2232    o create initial cd_code package
2233      - WARNING: the initialization of fields within packages
2234        is broken because INI_FIELDS (where READ_CHECKPOINT is
2235        called) is called *before* PACKAGES_INIT_VARIABLES.
2236        This seems to be backwards since
2237        1) its important to initially zero the entire field including
2238           the "halo" region
2239        2) zeroing needs to be done *before* reading pickup info
2240           and the pickup call might or might not happen in any
2241           particular run
2242      - this needs an overhaul for R2
2243    o cleanup verification/*/code/GMREDI_OPTIONS.h

2278      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
2279      - subroutine FREEZE now limits only surface temperature
2280        (this means new output.txt for global_ocean.90x40x15,
2281         global_ocean.cs32x15, and global_with_exf)
2282    o added surface flux output variables to TIMEAVE_STATVARS

2375      - See verification/global_with_exf/README for usage example.
2376      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
2377        flags and modified pkg/seaice accordingly.
2378    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
2379        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
2380        non-local transport term.
2381    
2382    checkpoint51e_post

2456    o somewhat cleaned package initialisation sequence for
2457      ctrl/ cost/ ecco/ in packages_... routines
2458    
2459    checkpoint50g_post

2485     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
2486       nearly a copy of kpp_transport_s
2487     - there is no analogue to SurfaceTendencyS, so I have to use
2488       gPtr(of the surface layer) instead
2489    o add a new platform SunFire+mpi (SunFire 15000) to genmake
2490    checkpoint50e_pre

2496      analogous to the cg2d-related output.
2497    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
2498      so that writing to internal file fn (with length 512) fails.
2499    checkpoint50d_pre
2500    
2501    checkpoint50c_post
2502    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)

2513    checkpoint50b_post
2514    o store u*,v* in gU,V instead of in guNm1,gvNm1
2515    o in order to put the momForcing out of the Adams-Bashforth:
2516      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
2517      to timestep.F
2518    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays

2526    
2527    checkpoint50a_post
2528    o Bug fix for merging between c50 and KPP.
2529      ikey was passed from thermodynamics to kpp_calc via
2530      common block rather than being recomputed in kpp_calc,
2531      in contradiction with new key itdkey.
2532      New key ikppkey created, and tamc.h headers updated.
2533    
2534    checkpoint50
2535    - 2nd step of merge with ecco-branch:

2546        (runtime) values.
2547      - in exf_getffields.F
2548        Reduce i-/j-loop to interior domain, discarding overlaps.
2549        That also fixes wrong TAF-key computations for key_1, key_2
2550        with bulf formulae.
2551      - exf_init.F modify #ifdef for exf_init_evap
2552      - exf_getffieldrec.F, ctrl_getrec.F
2553        The following INT-usages are not safe:
2554          fldsecs  = int(fldsecs/fldperiod)*fldperiod
2555          fldcount = int(fldsecs/fldperiod) + 1
2556        and were modified.
2557    o autodiff: checkpoint_lev...
2558      - updated storing for bulk formulae (some arrays were missing)
2559      - added state for seaice package
2560      - synchronized with main branch
2561    o DIVA:
2562      Modif.s in
2563      - the_main_loop.F
2564      - the_model_main.F
2565      and added cost_final_restore.F cost_final_store.F
2566      o With these changes, it is possible to fully separate
2567        the first forward run to compute the cost function (mdthe_main_loop)
2568        and adjoint runs over individual DIVA intervals (adthe_main_loop)
2569        into separate model executions.
2570        This enables better tuning of DIVA to given queue sizes.
2571      o Loss of cost function value in consecutive DIVA runs is
2572        fixed by storing to 'costfinal' file.
2573      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
2574        beginning/end of adjoint integration is accounted for.
2575      The current changes apply to TAF-1.4.26.
2576      TAF has one remaining bug, requiring one manual change
2577      (see MITgcm manual).
2578    o cal: synchronized between MAIN and ecco-branch
2579    
2580    checkpoint48i_post
2581    o Changes to restore differentiability of code w.r.t. previous tag
2582      (mostly adding new routines to make list and replacing
2583      pressure by totPhiHyd).
2584    o Updated and merged grdchk package
2585      - has both ADM and TLM checks
2586      - works for single- and multi-proc.
2587      - output cleaned
2588      - worked successfully for parallel DIVA
2589    o genmake:
2590      - Adding -platform=SP4
2591      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
2592    o Modif. for DIVA:
2593      ctrl_unpack should not be called in intermediate DIVA interval.
2594      (similar thing would apply for active files such as
2595      tbar, sbar, psbar, which should not be reinitialised;
2596      only relevant for ecco-branch)
2597    
2598    checkpoint48h_post
2599    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
2600    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
2601    o Added SEAICE_initialHEFF to pkg/seaice
2602    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
2603    
2604    checkpoint48g_post
2605    --- EOS:
2606    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
2607      store total Potential in totPhyHyd for diagnostics & EOS.
2608    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
2609    --- Pressure/geopotential gradient:
2610    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
2611    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
2612      ( changes results of global_ocean_pressure )
2613    o NLFS + z-coord.: add eta*Rho' contribution.
2614    o accurate phiHyd when using interface-W at the middle between 2 centers
2615     ( changes results of ideal_2D_oce )
2616    o includes r* 2nd term in potential gradient.
2617    
2618    checkpoint48f_post
2619    Merging from release1_p12:
2620    o Modifications for using pkg/exf with pkg/seaice
2621      - improved description of the various forcing configurations
2622      - added basic radiation bulk formulae to pkg/exf
2623      - units/sign fix for evap computation in exf_getffields.F
2624      - updated verification/global_with_exf/results/output.txt
2625    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
2626      (SBO) core products, including oceanic mass, center-of-mass,
2627      angular, and bottom pressure (see pkg/sbo/README.sbo).
2628    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
2629      to avoid negative values in shallow regions.
2630      - updated verification/natl_box/results/output.txt
2631      - updated verification/lab_sea/results/output.txt
2632    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
2633    o Added useSingleCpuIO option (see PARAMS.h).
2634    o Updated useSingleCpuIO option in mdsio_writefield.F to
2635      work with multi-field files, e.g., for single-file pickup.
2636    o pkg/seaice:
2637      - bug fix in growth.F: QNET for no shortwave case
2638      - added HeffFile for specifying initial sea-ice thickness
2639      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
2640    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
2641      kpp_transport_t.F, forward_step.F, and the_main_loop.F
2642    o pkg/seaice:
2643      - adjoint-friendly modifications
2644      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
2645    
2646    checkpoint48e_post
2647    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
2648    o dynamics: change definition of computational domain & adapt mom_fluxform
2649      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
2650    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
2651        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
2652        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
2653        global_ocean.90x40x15 global_with_exf global_ocean_pressure
2654        inverted_barometer solid-body.cs-32x32x1
2655      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
2656    
2657    checkpoint48d_post
2658    o in preparation for r*:
2659     a) use pre-computed gradient of hydrostatic potential:
2660        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
2661     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
2662        => affects results of glob_oce_pressure (different truncation error)  
2663      update output.txt of ideal_2D_oce & global_ocean_pressure
2664    
2665    checkpoint48d_pre
2666    o in preparation for r*:
2667      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
2668      pass the 2 comp. of the grad. as arguments to momentum S/R.
2669      but for the moment, only used if it does not change the results.
2670    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
2671    
2672    checkpoint48c_post
2673    Modifications in treatment of initial flux forcing controls
2674    to avoid extra storing of flux fields.
2675    
2676    checkpoint48c_pre
2677    o Added tidal_basin_2d experiment (currently 1D!)
2678    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
2679    
2680    checkpoint48b_post
2681    o r* coordinate added in #ifdef NONLIN_FRSURF block.
2682     (modification to pressure gradient not yet implemented)
2683    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
2684      (for U & V) that are used for vertical advection of momentum.
2685    
2686    checkpoint48a_post
2687    o In preparation for r*, use temp. array to compute vertical transport
2688       in flux-form momentum pkg. => change results of few test-exp.
2689      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
2690                        lab_sea, natl_box & plume_on_slope
2691    
2692    checkpoint48
