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