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