5      ==============================      ==============================
6    
7  untagged  o pkg/ptracers:
8      use use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
9      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
10    
11    checkpoint59j
12    o in pkgs: dic, obcs, offline, rbcs:
13      standard way to compute coeff. for time interpolation between 2 time reccords
14      which retains full precision (& make results less dependent on compiler).
15      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
16    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
17      packages instead of reading ice cover and wind speed separately
18    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
19     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
20      to allow to compile customized code before the update)
21    o cleaning-up:
22      - fix CPP instruction syntax in pkg/obcs
23      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
24        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
25      - fix some threads issue in IO parts.
26    o pkg/dic:
27      - add tons of "_d 0" (--> much better testreports !)
28       and then update outputs of tutorial_global_oce_biogeo
29    o pkg/mom_fluxform:
30      add a special version of momentum advection intended to conserve momentum
31      next to a bathymetry step or a coastline edge. (default = off = #undef)
32    o new read/write pickup version:
33      - for now, only implemented for main (mdsio) pickup file.
34      - write out only what is needed to restart; merge pickup_nh , pickup_ph
35        and main pickup together.
36      - read meta file; read only what is needed to restart; stop if a field
37        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
38        if it make sense (even if the restart is not perfect).
39      - if no meta file, assume that pickup to read corresponds exactly to
40        a pickup that would currently be written.
41      - read pickup written in the old format (until checkpoint59i) if it
42        recognizes an old meta file (no field-list).
43      - add a meta file in exp. which starts from a pickup: 2 cases:
44        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
45         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
46        b) a meta file describing the content of the associated pickup file
47         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
48    o pkg/mdsio & pkg/rw:
49      - new routine to read a meta file ; new set of routine to read
50        Multiple-fields file (with meta file).
51    o added open boundary conditions capability for seaice
52        HSNOW, HSALT, UICE, and VICE
53    
54    checkpoint59i
55    o adjoint:
56      * fix multiDimAdvection adjoint
57        (partial recomputation problem by TAF for fVerT(:,:,kDown)
58        and comlev1 size definition (maxpass vs. max. number of tracers)
59      * verification/global_ocean.90x45x15 adjoint now tests
60        NLFS and multiDimAdvection using DST3 (=30)
61      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
62    o pkg/kpp: add "_d 0" to real constant (if missing);
63      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
64      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
65    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
66      for internal parameters related to restart process (formerly from PARAMS.h)
67      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
68    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
69      as argument. (only atm2d & obcs write_pickup have not yet been updated)
70    o pkg/monitor:
71      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
72      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
73      - account for deep Atmosphere factor and density factor (anelastic)
74    o added open boundary conditions capability for seaice HEFF and AREA
75    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
76      thermodynamics
77      - requires a little reorganization, which affects the testreport results
78        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
79        so that now the conservative form is tested
80      - add a few comments
81    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
82    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
83    o add new diagnostics to seaice: advective, diffusive fluxes (only for
84      multidim-advection, for scheme 2 they are not filled) and transports,
85      thermodynamic growth rates
86    o change units of EmPmR (inside the code, + within coupling interface)
87      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
88      Affects results @ truncation level (cg2d match) and update output of
89       experiments: lab_sea(6), global_ocean.90x40x15(10),
90      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
91      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
92      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
93      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
94    
95    checkpoint59h
96    o pkg/exf:
97      - improve vectorization by moving if-statement out of loops in
98        exf_mapfields, exf_radiation
99      - exf_bulkformulae.F: introduce 2D fields and vectorize code
100    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
101    o testreport:
102      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
103        monitor & update offline_exf_seaice exp. output.
104      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
105    o pkg/seaice:
106      - bug fix in the evp solver: boundary conditions were affected be
107        masking of zMax/zMin (changes results)
108      - minor bug fix in boundary conditions in seaice_calc_strainrates
109        (changes results for no_slip)
110      - seaice_lsr.F: make interpolation of eta dependent on boundaries
111      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
112      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
113        stress formulation and no-slip boundary conditions
114    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
115      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
116    o pkg/seaice: a first HSALT time stepping equation has been checked in
117    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
118      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
119      without requiring DO-IF statements
120    o pkg/thsice:
121      use continuous power-law function for partition of energy between lateral
122      melting/freezing and thinning/thickening ; old code using step function
123      still available with #undef THSICE_FRACEN_POWERLAW
124      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
125    o testreport: change AD testing : check against results/output_adm.txt
126      using same scripts as for forward test.
127    
128    checkpoint59g
129    o adjoint testing: in preparation for changing testreport:
130      - output format: cost and grad written on separated lines
131      - ad output results in directory "results" (instead of "results_ad")
132    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
133    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
134    o pkg/ecco: allow user defined cost function contributions
135    o testreport:
136      Allow to choose (per experiment) the list of tested output variables
137       and the main variable (used to issue a pass/FAIL ) ;
138      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
139      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
140      Also modify printing of summary:
141       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
142       b) echo the list of tested variables in the individual summary.txt of
143          each experiment.
144    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
145      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
146      (but still depend on the tile decompostion of the domain).
147    o pkg/seaice: change a discretization detail to make the B-grid code
148      "more symmetric". This change is likely to remove all "ridges/leads" that
149      where quasi-aligned with the grid in B-grid solutions. It may also be
150      the solution to the stress coupling issues with the B-grid.
151    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
152      remove .cvsignore from input dir. (since testreport no longer run here).
153    o pkg/thsice:
154     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
155     - fix reshaping of sea-ice just after advection:
156       melt all the ice only if ice-volume is too small.
157     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
158       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
159     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
160    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
161      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
162    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
163      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
164      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
165      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
166      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
167      -> update output.txt
168    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
169     this affects truncation error: -> update output.txt of exp:
170      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
171      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
172    
173    checkpoint59f
174    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
175    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
176      a bounded range (in forward mode)
177    o pkg/ecco, ctrl, autodiff and mom_common:
178     internal parameter controls, completements of implementations
179    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
180    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
181      (not seem any difference in testing results).
182    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
183       at face corners.
184    o pkg/generic_advdiff:
185     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
186      loop range indices for computing vertical advection tendency
187      and do the calculation in the interior only (no overlap) ;
188      for now, only implemented for SOM advection (to save CPU time).
189     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
190    o exch2 adjoint
191      First set of changes:
192      - add exch2 hand-written adjoint templates
193      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
194        This will require cleanup in pkg/autodiff/*.F
195        (changed routines currently kept separate in verif. code/)
196      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
197        that used to hide exch2 or cubed-sphere specific code
198        (commented via 'cph-exch2')
199    o pkg/seaice
200      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
201    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
202       output of global_ocean.cs32x15.thsice .
203    
204    checkpoint59e
205    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
206      for B-grid vector (not yet tested) and C-grid vector (<- only used
207      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
208    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
209      (#ifdef ALLOW_SALT_PLUME)
210    o gather_2d/scatter_2d: removed halo regions
211    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
212      scheme and the corresponding test case (under front_relax dir). For now,
213      only available with Skew-flux form and not yet tested in realistic set-up.
214      adjoint: store directives updated, but gradient checks deteriorated,
215      so maybe GM/Redi adjoint is now broken.
216    o seaice adjoint
217      * add AREA, HEFF, HSNOW as control variable
218        (should not change lab_sea results)
219      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
220    o pkg/seaice:
221      * added computation of saltFlux in seaice_growth;
222        For time being, sea ice salinity is assumed constant
223        contribution of snow flooding to freshening of sea ice is neglected.
224        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
225        defaults to 0.0 in order to maintain backward compatibility.
226        Typical values for SEAICE_salinity are 4 to 10 g/kg.
227      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
228      * added SEAICE_availHeatFrac, which specifies fraction of surface level
229        heat content used to melt or grow ice
230      * commented out cap of HICE: it helps keep ice thinner
231      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
232      * applied OBCS T/S mask to HEFFM sea ice mask
233    
234    checkpoint59d
235    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
236     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
237     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
238    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
239     and change default value of parameter "GM_Small_Number";
240     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
241       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
242       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
243    o pkg/ecco: cost function when applying pkg/smooth to controls
244    o pkg/ctrl: add forcingPrecond run time parameter
245    o pkg/seaice:
246     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
247     - fix bug in metric terms of u-equation in LSR solver (implicit part),
248       changes verification/lab_sea
249     - rearrange implicit part of u-equation in LSR solver to make it easier to
250       read, understand, and debug. This causes changes at the truncation level.
251     - fix (serious) bug in the boundary conditions (sign error in the implicit
252       part) of the LSR solver. Changes all LSR results.
253     - fixed problem with HSNOW initialization to avoid thick snow when AREA
254       is initilized with small values - does not change lab_sea results.
255     - added HsnowFile initialization capability
256    o pkg/smooth: addition to model/src and pkg/ctrl so allow
257     initialization of pkg/smooth and application to control vector
258    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
259    o dependencies: pkg/profiles requires pkg/cal
260    o pkg/profiles:
261     - added option ALLOW_PROFILES_GENERICGRID
262         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
263         that interpolation information (grid points and coefficients) is provided
264         within the netcdf input files.
265         -> sample matlab scripts can be found in MITgcm_contrib/gael
266         that allow you to prepare netcdf input files.
267     - also modified: cleaner include statements, cleaner error print statements,
268       cleaner stops when error, and more tests of the netcdf input files consistency.
269    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
270    o pkg/seaice:
271     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
272       requires a new routine: seaice_diagnostics_fill.F
273     - make sure that seaice does not move if not forced (pressure replacement
274       method, Hibler and Ip, 1995), changes results
275     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
276     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
277       It is turned off by default (=-1.), because it changes the results.
278     - make it possible to read AREA from a file, too.
279    
280    checkpoint59c
281    o add S/R and diagnostics for oceanic mixed-layer depth
282    o move GMRedi call after all vertical mixing schemes (including KPP)
283    o pkg/thsice:
284     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
285      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
286    o pkg/obcs:
287     - bug fix for balance code
288    o pkg/seaice:
289      - allow values of SEAICE_elasticParm > 1
290      - add new parameter SEAICE_evpTauRelax as an alternative
291        to SEAICE_elasticParm
292      - make lsr boundary conditions free slip (by default), changes result
293      - add code for no slip boundary conditions for lsr
294      - set minimum of zeta to zero (and not 4e8) (changes results)
295      - add a cap on AREA after advecting AREA if seaice_growth is not called
296    o change calculation of Visbeck K:
297      - no longer depend on tapering scheme; instead, compute slope (limited
298        by GM_maxSlope). this is equivalent to what was comuted before with
299        clipping or linear tappering.
300      - fix vertical averaging (wrong by 1/2 level)
301      - leave the old version (but will not be maintained) within
302        #ifdef OLD_VISBECK_CALC / #endif
303      - update output of exp. ideal_2D_oce
304    o change error catch in calc_r_star to improve vectorization
305    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
306      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
307    o adjoint:
308      Re-organized adjoint checkpointing according to Matt Mazloff
309      (but with modifs/completions/cleanups)
310      Storing is now bundled into large arrays to optimized I/O
311      (and second step in cleanup of the_main_loop)
312    
313    checkpoint59b
314    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
315      - export/import (between ocean & coupler) fields needed for ocean DIC.
316    o pkg/seaice:
317      - get rid of three more exchanges seaice_calc_viscosities (required
318        different loop boundaries in seaice_lsr and seaice_ocean_stress)
319      - bug fix in seaice_ocean_stress (update of lab_sea required)
320      - reduce loop boundaries to necessary minimum also in seaice_evp
321      - go back to the old way of computing deltaC/Z as the adjoint likes that
322        better
323    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
324      passive tracer to an Age Tracer) + update output.txt
325    o pkg/exf:
326      - implement A-grid / C-grid selection for wind-stress input files.
327      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
328      for now, in exf_bulk_largeyeager04.F only :
329      - change implementation for case where windspeed + 2. components wind-stress
330        are read-in. AND use rhoConstFresh to convert evap.
331    o pkg/seaice:
332      - use correct EXCH_UV for wind-forcing (on A-grid).
333      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
334        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
335    o pkg/exf:
336      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
337      EXF_INTERPOLATION:
338      - merge global_with_exf/code version of exf_interp_read.F
339        to the main code ;
340      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
341        reading the file ; Important: This options needs to be defined to recover
342        previous code.
343        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
344      - no longer loose real*8 precision along the way when using exf_iprec=64.
345    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
346      - change discretisation of evp-solver in order to avoid another exchange
347        (changes lab_sea) and clean up a little
348      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
349        help the adjoint (this also changes the results slightly)
350      - add a few "_d 0" where they had been missing in seaice_evp.F
351      - cleaning up: remove unused seaice_calc_rhs.F
352    o pkg/exf: some cleaning-up:
353      - change various "constants" into runtime parameters
354      - cleaned-up Large&Yeager04 routine which should eventually
355        replace exf_bulkformulae.F (changed names of S/R and CPP)
356        and merged various ALLOW_ATM_WIND options
357     only used with thsice pkg (in thsice_get_exf.F):
358      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
359        which are used when useStabilityFct_overIce=TRUE (= the default)
360      - change default values of ice & snow emissivity and scale downward LW
361        by ice & snow emissivity.
362    o pkg/thsice:
363     fix few little problems, in thsice_calc_thickn.F:
364      - growth vertically (and not laterally) if iceFrac == iceMaskMax
365      - melt only laterally if hIce < hThinIce (as the comments say)
366      and in thsice_extend.F:
367      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
368      - start to form ice as soon as the minimum ice-volume is reachable.
369     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
370      and cpl_aim+ocn
371    o pkg/kpp
372     - move computation of surface related input fields to KPP into a new
373       subroutine kpp_forcing_surf.F
374     - remove wrong (within bi,bj loops) EXCH calls.
375     - little cleaning (add argument myThid in last position, cvs header ...)
376     - for now, fix conservation problem by exchanging KPPviscAz (may not
377       be the best fix)
378    o pkg/seaice
379     - check for inconsistent evp parameter/cpp-flag combination
380     - remove leftover errIO flat for obsolete name list error handling
381    o OpenAD
382     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
383    
384    checkpoint59a
385    o pkg/seaice: some parameter clarifications and a little bit of clean up
386    o pkg/thsice: rename run-time parameters:
387       himin       -> hIceMin
388       himin0      -> hThinIce
389       hihig       -> hThickIce
390       i0          -> i0swFrac
391       transCoef   -> bMeltCoef
392       frac_energy -> fracMelting
393      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
394       with default values (for now) that do not change the results.
395      remove old version of thsice vars advection in pkg/seaice.
396    o in FFIELDS.h:
397      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
398      - make pLoad & sIceLoad always available (but still only used if
399         ATMOSPHERIC_LOADING is #define).
400    o pkg/kpp: replaced _KPP_RL with _RL
401    o bug fixes for vertical diffusivity computations when both KPP and
402        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
403        are no longer updating the vertical diffusivity array
404        (passed as argument) but are (re-) setting those arrays.
405    o pkg/seaice: fix bug in evp solver, while doing that
406      - change (improve?) discretization of stress computations for both
407        cgrid-lsr and evp solver
408      - add a new routine to compute strain rates
409      - the above changes lab_sea results
410      - add no slip conditions for evp solver (off by default), lsr-version
411        may follow
412      - fix exchange for shear at Z-points (does not change lab_sea)
413      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
414        (to force the user to pick a time step since there is not "safe" way
415        of choosing it)
416      - add principal stress diagnostics
417      - rearrange fields for evp a little to avoid having to call a: too many
418        exchanges and b: exchanges for stress trensor components which we do
419        not have.
420      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
421        of evp, complete rewrite for lsr case (latter is does not yet work
422        in all cases)
423    o pkg/kpp: add code to have mixing in shelf ice caverns
424      - add myThid to all kpp routines (long overdue)
425    
426    checkpoint59
427    o pkg/exf:
428      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
429        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
430      - move exf header files from lower_case.h to UPPER_CASE.h ;
431        add missing cvs Header & Name
432      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
433      - add namelist param. selectStressGridPosition, exf_monFreq
434      - retire many _CLIM routines, and remove data.exf_clim
435        + params moved to data.exf
436        + climsst, climsss now handled by exf_set_gen, i.e.
437          climss?period=0 refers to constant field,
438          climss?period=-12 to monthly forcing
439      - split up namelists in data.exf
440    o pkg/seaice:
441      - remove seaice_exch and seaice_exch_uv
442      - remove superfluous exchange of theta
443      - add myThid to seaice_budget_ocean/ice
444      - add new interface for atmospheric wind forcing (C-grid only)
445        + new routine
446        + two new field (taux, tauy for stress over ice)
447        + removed one global field (DAIRN) for C-grid case only
448    o pkg/thsise
449      - 2nd set of modifs for thsice adjoint in conjunction with exf
450    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
451    
452    checkpoint58y_post
453    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
454      vertical diffusivity, similar to that in MOM4; turned on using
455      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
456      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
457    o Added capability for 3D specification of background vertical diffusion
458      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
459      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
460      "data" file that contains the 3D vertical diffusivity coefficients.
461    o ice dynamics (pkg/seaice) with thsice thermodynamics:
462      - add code within pkg thsice to advect & diffuse sea-ice fields
463      similar to (and will replace) what has been added in  seaice_advdiff.F,
464      but: - conserving Mass, Heat & Salt.
465           - better when using non-linear advection scheme (not yet fully tested)
466           - can also be used in atmospheric set-up (for now, only the diffusion).
467    
468    checkpoint58x_post
469    o IO option for global-file compact format:
470      - add options when generating topology (utils/exch2/matlab-topology-generator)
471      - add I/O capability (pkg/mdsio).
472      - adapt utils/matlab/rdmds.m to read this format.
473      for now long-line format not yet supported by pkg/mdsio (& exch2).
474    o shelfice: add a few diagnostics
475    
476    checkpoint58w_post
477    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
478      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
479      (and replace horiVertRatio in NH code).
480      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
481                         and tutorial_plume_on_slope (sensitive to truncation)
482    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
483      directly to drive seaice model (C-grid only)
484    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
485     - reintroduce computation of wind from stress,
486     - compute tau (in exf_bulkformulae.F) from windstress averaged to
487       mass points to avoid tau = 0
488     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
489    o rdmnc.m: make it work with "global" files created with gluemnc
490    o rdmnc.m : some improvements in dealing with singleton dimension
491      (tested on all testreport mnc output files).
492    o genmake2: disable pkg/profiles if netcdf test fails.
493    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
494    o move call to cal_readparms up to make calendar parameters/variable available
495      to all packages
496    
497    checkpoint58v_post
498    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
499      useDynP_inEos_Zc tested.
500    o pkg/exf: changes to properly interpolate/mask/scale initial fields
501    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
502      and portions thereof.  See read_cs.txt for description and examples.
503    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
504      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
505      following the great-circle arc between those 2 points.
506    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
507      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
508    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
509     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
510     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
511     - still needs work (not working with some options ; efficiency to improve)
512       and serious testing.
513     - use this scheme for temperature & salinity in 2 advection test exp.:
514       advect_xy & advect_xz, respectively.
515    
516    checkpoint58u_post
517    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
518    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
519    o testreport: add option "-skipdir" to skip some test.
520    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
521      momentum calculation.
522    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
523    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
524      remove checkpoint.F and the_correction_step.F (no longer used);
525      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
526    o add option (linFSConserveTr) to correct for tracer source/sink due to
527      Linear Free surface
528    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
529    o pkg/thsice: fix reading mnc-pickups
530    
531    checkpoint58t_post
532    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
533    o pkg/mdsio:
534     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
535       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
536       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
537     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
538     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
539       either MDS_READ_FIELD or MDS_WRITE_FIELD )
540     - new S/R (to replace MDSWRITEMETA), which allows to write more
541       informations (variable names, time ...) to meta files.
542     - modify rdmds.m to give back the meta file content.
543    o pkg/diagnostics: change vertical interpolation to be safer, and more
544       flexible (define p-levels to interpolate to in data.diagnostics);
545      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
546       diagnostic pointer.
547    o pkg/seaice: more cleaning up of seaice_growth, added many comments
548    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
549    o fix multi-category seaice:
550     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
551       SEAICE_MULTICATEGORY
552     - fix short wave heat flux
553    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
554       and allow to use EVP solver. Change forward lab_sea: test both EVP
555       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
556    o Initial check-in of lab_sea adjoint
557      (very similar to natl_box_adjoint/code_seaice)
558      * used C-grid and EVP solver
559      * used KPP, GM/Redi
560      * uses inAdExact=.TRUE.
561      * gradient checks fail for both ADM and TLM
562        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
563        f.d. gradients actually seem more problematic than ADM, TLM gradients;
564        issue is related to forward mismatch between g77 an ifort
565    o pkg/seaice: overhaul of thermodynamics
566     - growth.F and groatb.F are replaced by new routine seaice_growth.F
567     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
568     - move a few global fields out of SEAICE.h into seaice_growth.F and
569       make them 2D (FICE/QNETO/ ...)
570     - remove FO (it is the same as QNETO)
571     - introduce a few local fields to avoid modifying external fields such
572       as atemp, etc.
573    
574    checkpoint58s_post
575    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
576      changed exf_set_gen.F so that
577        genperiod=0 means input file is one time-constant field and
578        genperiod=-12 means input file contains 12 monthly means
579    o CG2D: use pre-computed solver main-diagonal (stored in common block);
580      this affects truncation error ; generate new output file for exp. which
581      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
582        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
583        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
584        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
585        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
586        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
587    o start implementation of deep-atmosphere and anelastic formulation
588    o verification: remove 2nd copy of input files and use script "prepare_run"
589      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
590    o mom_common/vecinv/fluxform: fix a few initialisation isssues
591    o profiles: fix for multithreaded case
592    
593    o diagnostics: rename few diags:
594      s/'PRESSURE'/'RCENTER '/g
595      s/'TICE    '/'oceFreez'/g
596      s/'TAUX    '/'oceTAUX '/g
597      s/'TAUY    '/'oceTAUY '/g
598      s/'SWFLUX  '/'oceQsw  '/g
599      s/DIFx/DFxE/g
600      s/DIFy/DFyE/g
601      and add few ocean-forcing diagnostics:
602      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
603    o modifications to pkg/seaice/growth.F and budget.F, which change results of
604      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
605      as actual snow thickness.  It now refers everywhere to effective snow
606      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
607    
608    checkpoint58r_post
609    o modifications to pkg/seaice/growth.F, which change results of
610      lab_sea experiment: fixes pertain to melting snow over open water, to
611      masking EVAP under sea ice, and to using the correct AREA variable for
612      computations of EVAP, PRECIP, HSNOW, and GHEFF
613    o add ability to read bathy, salt, and theta using MNC (off by def)
614    o add flooding algorithm and advection of HSNOW for pkg/seaice;
615      both are turned off by default and do no change any results
616    o seaice advection with pkg/thsice: a step toward the use of non-linear
617      advection scheme, but #ifdef or commented out for now (requires more EXCH).
618    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
619      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
620      in natl_box (affects results @ truncation level: update output.txt)
621    o multi-threading and IO:
622      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
623      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
624        (needed to work with SingleCpuIO): tested in all verif. exp.
625    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
626      affects the results (but none of the verification test uses this scheme).
627    o Adding some pkg/diagnostics capability to pkg/seaice
628      (will certainly be subject to changes)
629    o ctrl: adding new control variables:
630      lwflux, lwdown, evap, snowprecip, apressure, runoff
631    
632    checkpoint58q_post
633    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
634      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
635      high_res_cube configuration by 4% on Columbia.
636    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
637      add (in global_with_exf/code) a version of EXF_INTERP_READ without
638      dynamical allocation (seems to work in multi-threaded).
639    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
640      single CPU io) so that TAF does not have to see EESUPPORT.h
641    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
642    
643    checkpoint58p_post
644    o obcs: stop if obcs is used with useCDscheme = .true.
645    o shelfice:
646     - fix a sign error so that no slip at shelfice interface works
647     - remove stop for combination non-hydrostatic code and shelfice. That does
648       not mean, that the results are correct, but at least they are numerically
649       stable
650    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
651    o added adjoint exch routined for all exch*3d* routines
652      and updated flow directives
653    
654    checkpoint58o_post
655    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
656      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
657    o change controling S/R for writing pickup file (new S/R do_write_pickup)
658      and clean-up reading/writing of pickup files.
659    o fix local version of read/write pickup (NH part) in rotating_tank/code
660    o simplify EXCH interface:
661     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
662     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
663    o added the regrid package
664    o shelfice:
665     - add a simple boundary layer scheme to reduce noise
666     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
667    
668    checkpoint58n_post
669    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
670       local variable (not in common block).
671    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
672      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
673      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
674        to work with SingleCpuIO.
675    o add "_d 0" to real constant of pkg/cfc subroutines ;
676       update exp. cfc_exemple & tutorial_cfc_offline output files.
677    o multi-threading and IO:
678      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
679        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
680      - barrier before and after reading.
681      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
682      - avoid using MDS_WRITELOCAL for LAND pkg output.
683      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
684        common-block variables ; Allows multi-threading with master-thread IO.
685    o change default MAX_NO_THREADS from 32 to 4 ;
686      and stop cleanly when MAX_NO_THREADS is too small.
687    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
688    
689    checkpoint58m_post
690    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
691       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
692    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
693       keep global_ocean.90x40x15 (for AD testing) with former secondary test
694       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
695    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
696        add MITgcm_tutorials (= code + all the tutorials)
697    o ecco, option to compute cost for total ssh (mean+anom)
698    o consistent with addition of ptracer and ssh in pkg/profiles
699    o profiles: adding ptracer and ssh
700    o testreport: change multi-test output-file name
701      (from output.txt.{name} to output.{name}.txt)
702    o profiles: now ok for mutli-tiles case
703    o seaice: add 4 parameters for different advection schemes for area,
704      (effective) seaice thickness, enthalphy, and snow height. Their default
705      is the standard parameter SEAICEadvScheme
706    o calc_gw:
707     - add cosFacU in zonal viscous flux (harmonic.visc.).
708     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
709       of tutorial_plume_on_slope.
710    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
711    o calc_gw: true flux-form, account for horizontal grid spacing.
712      update rotating_tank results, but not plume_on_slope (affected at
713      truncation level, 11 digits).
714    
715    checkpoint58l_post
716    o calc_gw:
717     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
718     - remove side-drag for now (need to fix it); update plume_on_slope results.
719     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
720    o commit code to make SST/SSS weights spatially variable
721      (based on either variable in-situ or variable initial T/S weights)
722    o pkg/ecco:
723      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
724        now based on horizontally varying weights wthetaLev, wsaltLev
725      * cost_averagesflags now returns year indices in addition to day, month
726      * sflux balance is performed on annual basis
727        (sflxumm, sfluxmm2, bal_sfluxmm)
728      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
729        including separate counting and multipliers
730    o pkg/rbcs
731      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
732    
733    checkpoint58k_post
734    o testreport:
735     - always build in dir. "build" (if not there, mkdir build instead of building
736       & running in input)
737     - run in dir run (if it exists), in build otherwise.
738     - call prepare_run (if input/prepare_run exists)
739     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
740    o pkg/exf modifications to interpolation and rotation routines for more
741       reasonable treatment of North Pole singularity: for tracers North Pole
742       value is set to northernmost zonal-mean value, for zonal velocity it is
743       set to zero, and for meridional velocity it is set to northernmost value.
744    o pkg/exf/exf_check_range.F
745     - add tile index to diagnostics and move stop statement to the very
746       end of the routine.
747    o pkg/diagnostics: (diagnostics_main_init.F)
748      define title of isomorphic variables according to the current config.
749    o pkg/thsice with pkg/seaice dynamics:
750    - fix domain of computation (interior only, required for exf) and do exchanges
751    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
752    o towards a standard way of dealing with multi-threading in MONITOR
753      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
754    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
755       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
756    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
757    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
758    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
759       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
760    o tracer advection:
761     - clean-up and simplify calc_common_factors.F
762     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
763       advection subroutine (but still not used within DST advection S/R)
764    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
765    
766    checkpoint58j_post
767    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
768      from file (collects calls previously in FORWARD_STEP)
769    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
770    o adjoint store dir. adjusted accordingly
771    o genmake2
772      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
773    
774    checkpoint58i_post
775    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
776      on wind stress (SEAICEstressFactor defaults to 1.)
777    o Total number of Timers is finite (<=40): comment out 2 non-essential one
778      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
779    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
780      on CS-grid: no longer loosing mass.
781    o exf & curvilinear-grid: no longer modify longitude xC & xG.
782    o pkg/ggl90: fix sloppy output and fix a bug
783    o pkg/seaice: added SEAICEuseEVPpickup parameter
784      - Set to false in order to start EVP solver with
785        non-EVP pickup files when using SEAICEuseEVP
786      - fix sign error in diffusion in seaice_calc_rhs
787    
788    checkpoint58h_post
789    * Modifications for bottom topography control
790      o replace hFacC by _hFacC at various places
791      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
792      o add non-self-adjoint cg2d_nsa
793      o update autodiff support routines
794      o re-initialise hfac after ctrl_depth_ini
795      o works for 5x5 box, doesnt work for global_ocean.90x40x15
796    * Adding verification for 5x5 box (4-layer) bottom topography control
797    
798    checkpoint58g_post
799    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
800       used for mean seasonal cycle, mean diurnal cycle); add an example
801       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
802    o pkg/ggl90:
803      - add parameter (minimum surface kinetic energy)
804      - fix bug (avoiding division by zero)
805    o couple pkg/thsice to pkg/seaice:
806      - modify advection in seaice to accomodate new scalar fields to be advected
807      - only muliDimAdection scheme work with seaice/thsice
808      - mapping of thsice-variables to seaice-variables, back and forth
809      - does not break the verification experiments, but does not give the
810        desired results either
811    o pkg/seaice
812      - make (default) second order advection a bit less confusing?
813    
814    checkpoint58f_post
815    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
816      to pkg/seaice):
817      - new routines thsice_map_exf and thsice_get_exf provide the interface
818      - add an additional formal parameter to thsice_solve4temp
819    o pkg/exf:
820      - add new fields wspeed, snowprecip (to be able to couple to thsice)
821      - correct Stefan-Boltzmann constant
822      - new parameter for longwave surface emittance
823      - separate some stuff from exf_bulkformulae into new routines  
824        exf_radiation, exf_wind
825      - add new parameters and constants: longwave emissivity for ocean, ice
826        and snow, evaporation parameters over ice
827      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
828        either wind from stress or stress from wind
829    o pkg/thSIce:
830    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
831    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
832       and THSICE_CALC_THICKN
833    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
834    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
835      to make debugging easier.
836    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
837    o pkg/bulk_force:
838      - clean-up comments and parameters ;
839      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
840    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
841      generate new output for test-experiment: aim.5l_cs.thSI
842    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
843      testreport accordingly
844    
845    checkpoint58e_post
846    o SEAICE_CGRID adjoint done
847    o R_STAR adjoint implemented.
848      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
849      * need to sort out init. of h0facc, etc.
850    o Make pkg/profile fully independent of ecco,cost, etc. stuff
851      to be able to use it in pure forward.
852    
853    checkpoint58d_post
854    o upgrade simple test-experiment to tutorial example:
855     step.1: duplicate the experiment and (step.2) will remove the old copy.
856      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
857      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
858      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
859      tutorial_global_oce_biogeo    <- copy of dic_example
860      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
861      tutorial_plume_on_slope       <- copy of plume_on_slope
862      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
863      tutorial_global_oce_optim     <- empty for now (David ?)
864      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
865     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
866    o correct a sign problem in cost_scat.F
867    o obcs and ptracers: fix boundary conditions for advections schemes
868      with larger stencil
869    o thsice adjoint: start
870    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
871      completeness
872    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
873      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
874    o ptracers adjoint:
875      * avoid extensive recomputatations
876      * fix missing re-init. of gptr (missed by TAF)
877    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
878      me to turn off the excessive output to STDOUT that this package produces
879    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
880      and add those terms in Vector-Invariant formulation.
881    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
882      if the control period (xx_hfluxperiod etc) is 0
883    o in profiles pkg, clean routines and fix details
884    o in ecco pkg, reading ssh data:
885      fix problem in case the model does not start at iter0=0
886    o fix mnc-pickup/restart for ptracers
887    o new package prifiles:
888      code to compute profile-based cost by Gael Forget
889      (modifs in ecco, ctrl, autodiff)
890    o Benign bug fix in initialization (spotted by M. Mazloff) of
891      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
892    
893    checkpoint58c_post
894    o adjoint: finish NLFS adjoint and provide reference output in
895      verification/global_ocean.90x40x15/results_ad_nlfs
896    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
897      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
898      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
899      with SEAICE_CGRID defined.
900    o move calendarDumps from "data" to "data.cal" and clean-up the code
901      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
902    o add useEXF & useCAL flags (for now, set in hard-coded way)
903    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
904      (were missing in NH mode, and wrong in quasihydrostatic mode).
905      waiting for Chris updated version of calc_gw to add those CALLs.
906    o fix bug in quasihydrostatic S/R ;
907      add a test for this option: global_ocean.90x40x15.qshyd
908    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
909      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
910    o add on/off flag useOffLine for package OFFLINE
911    o seaice:
912      - modify advection so that it works also on the C-grid
913      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
914        problem in multi-tile runs with C-grid
915      - add flags for clipping ice velocities and/or masking solver forcing
916      - fix drag (ocean on ice) formulation and a bug that caused noise in the
917        C-grid solver
918      - added a few comments to seaice_diffusion.F
919      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
920        are now exclusive)
921      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
922        required re-ordering the code a little:
923       + make DAIRN global variable (defined in SEAICE)
924       + move computation of the viscosities eta and zeta into a new separate
925         routine (because I need to recompute them in seaice_ocean_stress.F)
926    
927    checkpoint58b_post
928    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
929      update output.txt of exp. aim.5l_cs.thSI
930    o various mnc cleanups and improvements:
931      + shrink lookup tables by factor of ~4
932      + better error reporting when running out of lookup space
933      + able to handle longer path/file names (up to 500 chars)
934    o adjoint:
935      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
936      - TBD: "hidden" mom_vecinv recomp. in dynamics
937    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
938     (allow to differentiate between forcing components using new integer flags:
939      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
940     and add new flag to put Dissipation tendency out of Adams-Bashforth.
941    o ecco
942      - enable trend removal from SSH anomaly obs.
943    o adjoint
944      - a fix for PmEpR when #undef EXACT_CONSERV
945      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
946      - try to fix "hidden" recomp. in forward_step for NLFS
947        (NLFS seems broken sometimes after I checked it in)
948    o seaice:
949     - add c-grid version of the dynamic solver:
950       + three new routines that are the c-grid substitute lsr, dynsolver
951         and ostres
952       + put a few fields that were local to dynsolver into global common
953         blocks, so that I can move the computation of stresses etc into
954         seaice_lsr (saves coding but may break the adjoint).
955     - replace more hardwired parameters by runtime parameters
956     - add ice masks that mask the rhs of the implicit solvers where there
957       is no ice (commented out in seaice_dynsolver, because i am not sure
958       if this works properly), eventually this should replace the clipping
959       of ice velocities in seaice_dynsolver to +/-40cm/s.
960    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
961      include it only where its needed
962    o move balancing of fluxes before the call of external_forcing_surf
963    o seaice:
964      - correct units of turning angles (now they are really in degrees)
965      - move computation of GWATX/Y out of main routine into dynsolver
966      - initialize GWATX/Y in seaice_init
967    o Apply mask on Fresh-Water flux (needed for SSH forcing).
968      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
969    o seaice: add runtime flags for turning angles (default to zero)
970    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
971      and trend from exf forcing and ctrl control adjustments
972    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
973      (since checkpoint57x_post)
974    o change the default rotation period to 86164.s = the Earth rotation
975    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
976      and based on a reference stratification. Tested within hs94.cs-32x32x5.
977    o seaice advection: add code for choosing between the default (2nd order
978      central differences) and multiDim advection schemes provided by
979      pkg/generic_advdiff
980    o seaice:
981      - removed all references to SEAICE_GRID.h fields from
982        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
983        (cubed-sphere configuration will change a little)
984      - grid computations in seaice_init are obsolete now.
985      - cleaned up code a little so that is easier to read (hopefully).
986      - added new (better?) discretizations of default advection and diffusion
987        (turn on with SEAICEuseFluxForm)
988      - replace 1 in 3d global fields by kSurface in growth.F
989      
990    checkpoint58a_post
991    o seaice:
992      - bug fix in advect.F
993    o shelfice:
994      - separate shelfice load anomaly from pload (breaks with time
995        dependent forcing), => introduce constant field shelficeLoadAnomaly.
996        Its default is 0., but it may be computed more cleverly from (unknown)
997        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
998        done offline. A good approximation of the pressure load anomaly is
999        necessary to avoid large initial adjustment processes underneath
1000        deep-reaching shelfice.
1001      - small fix in ISOMIP shelfice_thermodynamics
1002      - add more sophisticated thermodynamics of Hellmer (1989), this is
1003        now the default
1004      - give a few constants more intuitive names
1005    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1006      if bulk formulae are used in long integration (especially EmPmR). Turn
1007      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1008      if balancePrintMean, the imbalance that is substracted is printed to
1009      STDOUT.
1010    o fix bug (typo) in obcs_apply_eta.F
1011    o add a new package shelfice which enables us to model the circulation
1012      underneath shelf-ice with draughts of hundreds of meters.
1013     - works
1014     - to do: + include improved thermodynamics
1015              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1016                instead of new field kTopC
1017              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1018                instead of new field R_shelfIce and new code in ini_depth.F
1019                and ini_mask_etc.F?
1020              + adjust vertical mixing schemes?
1021    o seaice pkg:
1022     - add a cpp-flag to include a simple formula for a salinity dependent
1023       freezing point of sea water at the surface
1024     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1025       meridional stresses are now different (and hopefully correct)
1026    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1027       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1028       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1029    o pkg/diagnostics: add options and parameters for regional-statistics
1030       diagnostics ; define regions by reading a region-mask from a file
1031       (might add other options later)
1032    o pkg/bulk_force:
1033     - add option and parameters to use AIM surface-flux formulae.
1034     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1035       others forcing fields (defined in PARM05, parameter file "data") are loaded
1036       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1037     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1038     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1039     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1040       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1041     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1042    
1043    checkpoint58
1044    o add "--embed-source" option to genmake2 which, when the supporting
1045      tools can be compiled (as determined by genmake2) will turn on the
1046      embed_files package which then embeds the entire MITgcm source code
1047      (*.[fFhc] + Makefile) used for the build within the executable
1048      - requested by CNH but off by default
1049      - adds a paltry <9MB to the mitgcmuv executable in most cases
1050      - only writes the output when useEMBEDSRC in eedata is true
1051    o clean up 3-dim. relaxation codes:
1052      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1053      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1054      * Thanks to Tom Haine for testing!
1055    
1056    checkpoint57z_post
1057    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1058      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1059    o fix the pickup behavior for obcs in combination with ptracers
1060    o fix a bug in ptracers_external_fields_load
1061    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1062      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1063    o transfered surface NH pressure to eta field (if exactConserv).
1064    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1065         and update lab_sea output.txt file.
1066    o completing 3-dim. relaxation code: additional term
1067         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1068      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1069      * At compile time, in "EXF_OPTIONS.h" set
1070          #define  ALLOW_CLIMTEMP_RELAXATION
1071          #define  ALLOW_CLIMSALT_RELAXATION
1072      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1073          tauThetaClimRelax3Dim = 15552000.0,
1074          tauSaltClimRelax3Dim  = 15552000.0,
1075      * 3 cases:
1076          1) Use a constant-in-time 3-dim. field
1077          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1078          3) Real-time relax. to time-evolving prescribed field
1079    o Adding Laplacian-type smoothness constraint on
1080      initial and boundary (forcing) controls (ic, bc)
1081      * enable at compile-time via
1082        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1083      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1084      * Absolute scale somewhat unclear so far
1085      * no area weighting was included since no other cost term does so far
1086    
1087    checkpoint57y_post
1088    First step for a NLFS adjoint
1089    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1090    o new init. routines for calc_r_star, calc_surf_dr
1091    o still need to deal with ini_masks_etc
1092    o testreport seemed happy
1093    checkpoint57y_pre
1094    
1095    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1096    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1097    o add new offset feature to offline pkg (plus minor cleanup)
1098    o cfc fixes for final year of integration
1099    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1100      be in GCHEM_OPTIONS).
1101    
1102    checkpoint57x_post
1103    o fix testreport Pb in multiple test experiment.
1104    o cleanup our namelist syntax in verification:
1105      - make it more F95 standards compliant (some work still needed)
1106      - allows the vast majority of our tests to work with gfortran
1107    o Non-Hydrostatic:
1108     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1109     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1110    o Allow to apply AB on T,S rather than on AB(gT,gS):
1111     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1112     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1113       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1114     - need a "clever" read_pickup to restart from the other AB formulation
1115    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1116    o remove some unused variables (reduces number of compiler warnings)
1117    o adjoint
1118      * Disable useVariableViscosity for adjoint for time being
1119        (there are a number of extensive recomputations)
1120      * Initialize certain variables needed for adjoint
1121    
1122    checkpoint57w_post
1123    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1124                 fix the singleCpuIO RS version of MDSWRITEFIELD
1125       and add a WARNING if using globalFiles=T with multi-processors.
1126    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1127      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1128    o tracer advection scheme:
1129      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1130       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1131       was not very convenient).
1132      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1133       (further tests needed for the implicit DST & Flux-Limiter schemes).
1134    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1135      and sRef for convenience, handy, when you want to initialize
1136      ptracers in a large domain with a constant non-zero value. Also,
1137      untangle ptracers_init.F a little.
1138    
1139    checkpoint57v_post
1140    o change dome exp. to use variable viscosity in side-drag terms.
1141    o remove all the files from the cfc_offline test since they are now
1142      incorporated into tutorial_cfc_offline which has been producing
1143      identical results for a few days of testing
1144    o add new parameter: sideDragFactor to enable half-slip-side BC
1145      and change side-drag S/R to use viscosity from mom_calc_visc
1146      (can switch back by setting sideDragFactor=0.); affects results at
1147      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1148       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1149    o vorticity & strain are now computed without masking, to account for
1150      no-slip-side BC in variable viscosity calculation ; mask is applied
1151      anyway later on, before computing advection/coriolis terms.
1152    o modify exp4 to test new obcs support for reading from external files
1153      and for passive tracers
1154    o fix behavior of ptracers_monitor when monitor output is written to a
1155      netcdf-file; still not independent of monitor.F (writes in the same
1156      file).
1157    o change default value of tRef (put a uniform, meaningful value for ocean
1158      & atmos) and initialize sRef (was missing, as Martin mentioned).
1159    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1160      to be proportional to enstrophy dissipation length.  Thus,
1161       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1162      This is now consistent with Smagorinsky and with the manual.
1163    
1164    checkpoint57u_post
1165    o OBCS and PTRACERS: add open boundary support for passive tracers
1166      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1167        OB-values from file; this is not different from the way theta and salinity
1168        are treated
1169      - however, Orlanski-radiation conditions are not supported, and the model
1170        will stop if you use pTracers and Orlanski at the same time.
1171      - beefed up the rountine obcs_external_fields_load: now only those open
1172        boundary values are overwritten with values from files for which there
1173        are really files, otherwise the OB-fields remain untouched. This makes
1174        it possible to use different OBs at different ends of the domain (as
1175        with EXF)
1176    o reduce number of exch calls in shap_filt (s2).
1177    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1178      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1179    
1180    checkpoint57t_post
1181    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1182    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1183      same truncation, independent of the face number: affects affects several
1184      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1185    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1186      note that biharmonic viscosity + no-slip was not tested in any experiment.
1187    o fix bug in non-linear free-surf side-drag ; generate new output for
1188      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1189    o make mnc honor the writeBinaryPrec flag for most kinds of output
1190    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1191    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1192      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1193    o add brackets in multi-terms sum to get same truncation, independent of
1194      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1195      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1196    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1197      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1198      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1199      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1200      Suggested values of viscosity parameters found in mom_calc_visc.
1201      Many new viscosity diagnostics available.
1202    
1203    checkpoint57s_post
1204    o Add clearing-house for viscosity calculations, mom_calc_visc and
1205      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1206      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1207      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1208      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1209      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1210      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1211      ViscAhStrain and viscAhTension are now retired.
1212    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1213    o In response to JMC's bug report, genmake2 now ignores any soft-links
1214      that it finds in the *current* directory when searching for files.
1215      Soft-links found in any other source directories will still work as
1216      they did before.
1217    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1218      a C routine to unlimit the stack size
1219    o mnc-ify pkg/aim snapshot vars
1220    o mnc-ify pkg/land as requested by Daniel
1221    o various changes to mnc including:
1222      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1223      - output can now be grouped so that all files within a group
1224          change the ITER portion of their names in lock-step together
1225      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1226          and works with both EXCH1 and EXCH2 (but needs more testing)
1227      - writing works for all verification test cases w/ g77 on Linux
1228    
1229    checkpoint57r_post
1230    o make MNC variable initialization happen earlier
1231    o add diagnostics for (almost) each term of the momentum Eq.
1232    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1233    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1234    o remove MINIMAL_TAVE_OUTPUT option ;
1235      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1236    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1237      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1238    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1239    o add time-dependent SST, SSS control
1240    o cost terms in ecco/ modularized (new cost_generic.F)
1241    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1242    o new infrastructure for seaice model vs. obs misfits in seaice/
1243      * driver from the_main_loop.F is seaice_cost_driver.F
1244      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1245      * gradient check in Exp. 6a of natl_box_adjoint/
1246    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1247      (see README file)
1248    
1249    checkpoint57q_post
1250    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1251    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1252      - bug was reported by Jean-Michel and Ian Fenty
1253    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1254      update exp. cpl_aim+ocn output.
1255    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1256      Needed for high-res. runs with large global files
1257      to be able to limit tapelev size
1258    o Changed some tests for adjoint:
1259      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1260      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1261      * global_ocean.90x40x15/ back to default 3-level checkpointing
1262    o Modifications to enable scripted COMMON to MODULE conversion
1263      * verification/OpenAD/code/ has necessary scripts and description;
1264      * converts, compiles and runs successfully;
1265    
1266    checkpoint57p_post
1267    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1268    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1269      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1270    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1271    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1272      (was already the case for dissipation with mom_vecinv,
1273       and also the case for grad.PhiHyd when staggered-timeStep)
1274      This will allow to put dissipation out-off the AB time-stepping.
1275     Unfortunately, affects truncation error. Update output of exp. that "fails"
1276      (cg2d matching number) and leave the others for later: front_relax(10),
1277      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1278      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1279    
1280    checkpoint57o_post
1281    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1282      (2) its ready to be documented during the 20050801 DocFest
1283    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1284      for ideal_2D_oce and lab_sea on linux_ia32_g77
1285    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1286      in global1x1_tot/code_seaice_adj to access indices 32, 33
1287      (worth another tag)
1288    
1289    checkpoint57n_post
1290    o adding precip control xx_precip 32
1291    o adding swflux control xx_swflux 33
1292    o Replacing 10 forcing penalty cost routines by 1 generic.
1293    o Implementing partitioning in time-mean and variable adjustment
1294      for atmos. state.
1295    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1296    o in natl_box_adjoint:
1297      * updated exp 1 to 10
1298        (but does not have time-mean vs. variable split results yet)
1299    o updated global1x1/*_seaice_adj/
1300      to incorporate latest changes
1301    o enable useSingleCpuIO for mdsio vector routines
1302      (applies in particular to tapelev I/O)
1303    o removed inefficient K-loop in all active_file*control*.F
1304    
1305    checkpoint57m_post
1306    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1307      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1308    o pkg/exch2: filling of face-corner halo regions is optional
1309      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1310    
1311    checkpoint57l_post
1312     tag before updating tutorials (pre-release-2)
1313    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1314       for output and interpolation of input fields onto model grid)
1315    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1316       Affects results of exp. rotating_tank ; update output.txt.
1317    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1318          and taking the square quantity and/or using a fraction-weight field.
1319    o fix aim_diagnostics_init.F mate numbers.
1320    o add mnc output capability to diagnostics/diagstat and update
1321      our cvsignore files for the ACSII output generated
1322    
1323    checkpoint57k_post
1324    o lab_sea now uses diagnostics package and provides a suite of
1325      new EXF diagnostics output.
1326    
1327    checkpoint57j_post
1328    o exf
1329      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1330        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1331        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1332      * extended diagnostics output
1333        - now includes all EXF variables
1334        - hs, hl moved to common block
1335        - separate S/R for diagnostics, called after ctrl vector is added
1336        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1337        - EXFqnet contains true Qnet (i.e. includes qsw)
1338      * updated verif. lab_sea, global_with_exf
1339      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1340        to ensure that diagnostics sees a true EXFqnet
1341    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1342    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1343      several times with different frequencies.
1344    o mnc-ify the thsice package as requested by Daniel Enderton
1345      - the monitor--MNC output needs work
1346      - many attributes need to be added (most are currently blank)
1347    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1348      - many attributes need to be added (most are currently blank)
1349    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1350    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1351    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1352      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1353         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1354    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1355     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1356    
1357    checkpoint57i_post
1358    o Diagnostics package was changed: diagnostic allocation is now deactivated
1359      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1360    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1361      add 1rst Order upwind vertical Shear.
1362    o add a quick fix for A/B checkpointing in OFFLINE mode
1363    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1364      end-run around the C/Fortran linking horror in eesup/src/timers.F
1365    o added pkg/runclock: allows user to terminate run based on wall clock
1366    o added non-hydrostatic scaling parameter: nh_am2
1367    o pkg/my82: futile attempt to make results compiler-independent by adding
1368      some "_d 0", etc. no effect.
1369    o for mnc output, fill the 'T' coordinate var with myTime and create a
1370      separate 'iter' variable for iteration count
1371    o pkg/diagnostics:
1372      add new capability: output of Global/Regional & per-level statistics ;
1373      tested against monitor output (including land & thSIce) on various exp.
1374    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1375    
1376    checkpoint57h_done
1377      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1378      data.diagnostics, data.gchem, data.ptracers) is done.
1379    
1380    o pkg/diagnostics: prepare for Global/Regional statistics.
1381      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1382    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1383      and rename it: DIFFERENT_MULTIPLE
1384    
1385    checkpoint57h_post
1386    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1387    o pkg/diagnostics: change output frequency, now in seconds (instead
1388      of Nb of iterations). This requires to change data.diagnostics.
1389    checkpoint57h_pre
1390    
1391    o in mnc, let the user create the output dir if both mnc_outdir_date
1392      and mnc_outdir_num are false
1393    o add fflags() to pkg/diagnostics which allows one to specify, on a
1394      per-file basis, the file precision [default behavior is unchanged]
1395    o added diagnostics to pkg/kpp, including computation of mixed layer
1396      depth based on a temperature/density criterion
1397    o updated verification/natl_box to test the new pkg/kpp diagnostics
1398    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1399    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1400    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1401      not mnc -- this mistake was found by JMC and is now corrected
1402    
1403    checkpoint57g_post
1404    o add Adams-Bashforth 3rd Order time stepping:
1405      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1406      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1407    checkpoint57g_pre
1408    
1409    o make lambda[Theta,Salt]ClimRelax spatially varying
1410      (default remains spatially uniform constant based on tau)
1411    o added new control variables
1412      * init. uVel, vVel, etanN
1413      * lambda[Theta,Salt]ClimRelax
1414    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1415      (suggested by G. Forget)
1416    
1417    checkpoint57f_post
1418    o add parameter "baseTime" = model base time = time at iteration zero
1419      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1420      account for baseTime shift
1421    o move Coriolis arrays from PARAMS.h to GRID.h
1422    checkpoint57f_pre
1423    
1424    o mnc-ifying the seaice package
1425    o introduced an alternative length scale calculation for use in the limiting
1426      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1427    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1428    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1429      as well as grad(vort3).  Made it compatible with both approximate form
1430      for the cubed sphere and full form of these gradients.  Added flag
1431      useFullLeith to select between approximate and full form.  
1432    o add "d0" in getcon.F to reduce differences between compilers/platforms
1433      update output.txt of exp. fizhi-gridalt-hs
1434    o change port_rand funtion to allow to set the seed.
1435    o fix obscure MNC bug involving conversion between reals and integers
1436      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1437        new version is now more standards-compliant
1438    o adjoint-related modifications
1439      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1440      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1441      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1442    
1443    checkpoint57e_post
1444    o Adding eddy stress controls a la Ferreira et al.
1445    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1446    
1447    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1448      update output.txt of exp. fizhi-gridalt-hs
1449    o add more "Z" dimensions and associated coordinate vars to MNC
1450    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1451    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1452      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1453      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1454      months and years.  Requires pkg/cal.
1455    o diagnostics: add pickup functionality
1456      - off by default for backwards compatibility
1457      - current version only uses MDSIO -- MNC will be added
1458    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1459    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1460    
1461    checkpoint57d_post
1462    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1463    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1464      output from the diagnostics package
1465    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1466    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1467      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1468    o add coordinate variables to the MNC output from the diagnostics package
1469    o change MNC-flags default value: true when useMNC=TRUE
1470    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1471      the ability (off by default) to read the grid information using MNC
1472    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1473    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1474    o do snap-shot diagnostics at the middle of the time-interval (instead of
1475      at the end).
1476    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1477      new test for AIM with thSIce + slab-ocean
1478    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1479    o move state variable diagnostics to the beginning of the time step ;
1480      (note: still needs some work specially for snap-shot diagnostics)
1481      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1482    
1483    checkpoint57c_post
1484    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1485    o generate new output.txt files on faulks with g77 & the new -ieee option
1486    checkpoint57c_pre
1487    
1488    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1489      update output.txt of exp. global_ocean.90x40x15
1490    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1491      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1492    o add saltFlux(+File) forcing capability with periodicExternalForcing
1493    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1494    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1495    o improvements for the MNC output from DIAGNOSTICS:
1496      - correct handling of the unlimitied dimension
1497      - all dims now have associated coordinate variables
1498      - variables located at U, V, and Corner ("Z") points are now written
1499        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1500        *all* data points are output
1501    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1502    o added pkg/seaice/seaice_monitor.F
1503    o mdsio_readfield.F can now read files visible only to master MPI process.
1504    o pkg/seaice: some test code for ice-modified ocean stress
1505    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1506      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1507      spurious negative numbers for precipitation and humidity.  Will cause
1508      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1509    o pkg/ctrl/
1510      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1511        May be enabled via doPackDiag
1512      *  introduce z-scaling of
1513         + gradient (doZscalePack) and
1514         + control (doZscaleUnpack)
1515    o pkg/mdsio/
1516      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1517      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1518    
1519    checkpoint57b_post
1520    o simplify options in diagnostics_fill arguments (remove weird combinations)
1521    o fix MNC coordinate variables so that they now contain per-face index
1522      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1523      general, EXCH2 grids are only aligned to a "local" coordinate system
1524    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1525    o Implement instantaneous output within pkg diagnostics:
1526      setting a negative frequency in data.diagnostics produces
1527     "snap-shot" output (as opposed to time-average if freq > 0)
1528    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1529      NOTE: change ptracer diagnostics name: use 2 characters to work with
1530            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1531    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1532      becomes the coordinate variable for the 'T' dimension
1533    o add CF-style coordinate variables to MNC
1534      - just a first cut:  numbers are meaningless on the cubesphere and
1535        missing along the T axis but otherwise it works!
1536    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1537    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1538    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1539      this is based directly on what the model compute, so that the content of
1540      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1541    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1542    o clean up build options files for SunOS, in particular
1543      - remove -traditional from xmakedepend
1544      - change -xarch=v9 to -xarch=native for f77
1545      - restore use of make (not gmake)
1546      - add CC=gcc if using g77
1547    o changes per discussion of AM, JMC, & EH3 today:
1548      - move redundant "grid" variables out of "state" -- in preparation of
1549        creating proper CF-style coordinate variables and in recognition
1550        that any/all grid variables can be easily copied (eg. w/NCO) from
1551        the grid files into any of the other NetCDF files
1552      - *always* output grid variables with MDSIO (this will eventually be
1553        changed)
1554      - output MNC grid file if useMNC is true
1555    o every instance of _END_MASTER() has been found and replaced with
1556      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1557      preprocessors
1558    o re-arrange diagnostics pkg initialisation:
1559     - allow each package to extend the available diagnostics list
1560     - add some checking and fix small problems (multi-threaded, ...)
1561     - new S/R diagnostics_fill (replace fill_diagnostics):
1562       look through the short list of active diag. (instead of the long list)
1563       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1564    
1565    checkpoint57a_post
1566    o this set of changes restores TAMC compatibility
1567      tested for global_ocean.90x40x15 adjoint on trough
1568      (what a pain)
1569    
1570    checkpoint57a_pre
1571    o some modifs in tools/build_options for sunos
1572    o call ctrl_pack for ctrl at end for optimcycle=0
1573    
1574    checkpoint57
1575    o add horizontal bi-harmonic viscosity for vertical velocity
1576      - new parameter viscA4W (defaults to viscA4)
1577      - affects only non-hydrostatic code
1578      - to be done: no-slip lateral boundary conditions
1579    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1580    o implement Implicit Vertical advection for pTracers
1581    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1582      (implemented also for implicit vertical diffusion & advection)
1583    o OBCS: extend application of tracer open boundary conditions
1584      to a strip beyond the boundary of width Olx/Oly
1585    o add call monitor to TAF set of required calls (flow directives)
1586      and include in natl_box_adjoint
1587    o untangle a few ifdefs related to cost, ctrl, autodiff
1588      untangel a few ALLOW_ECCO_OPTIMIZATION
1589    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1590      (theta2, salt2 in ecco_cost_weights)
1591    
1592    checkpoint56c_post
1593    o OBCS as control variables
1594      - update ctrl_ad_diff.list, obcs_ad_diff.list
1595      - remove balance of obcs controls from default
1596      - fix index bug nobcs in ctrl_init
1597      - fix dummy fields filen in ctrl_pack
1598      - add dummy weights for obcs
1599    o lsopt: comment out fort.94 output
1600    o optim:
1601      - remove unnecessary header files
1602      - adjusted namelists
1603      - add xerbla.F to Makefile
1604    o exf:
1605      - multiple modifications of exf_check_range
1606      - unit change in exf_init_runoff from [m/year] to [m/s]
1607    o mdsio:
1608      - i/o-vector change debugLevel from debLevA to debLevB
1609    
1610    checkpoint56b_post
1611    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1612      is called from DO_THE_MODEL_IO
1613      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1614      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1615      - clean up PTRACERS_WRITE_TIMEAVE a little
1616    o add another verification experiment that tests both the cfc-pkg and
1617      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1618      reactive tendencies treated inline with regular timestepping
1619    o testreport previously did a lousy job of comparing small numbers, so
1620      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1621      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1622      testreport.
1623    o ptracers_monitor: bug fix for MPI
1624    
1625    checkpoint56a_post
1626    o GCHEM: finish reorganizating the package
1627      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1628        (introduces another 3D-array for each passive tracer, but only if
1629        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1630        gchemTendency is not needed because the timestep is done separately)
1631      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1632      - GCHEM is now---more or less cleanly---separate from PTRACERS
1633      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1634        so clear to me how that should be done in a general way.
1635    o CFC: improve formatting of output in CFC_ATMOS
1636    o PTRACERS:
1637      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1638        that ALL experiments with ptracers enable can be checked. This makes
1639        GCHEM_MONITOR obsolete.
1640      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1641        monitorFreq
1642      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1643    o add PTRACERS (PTR0[1-5]) to testreport output
1644    o exf_check_range:
1645      * default changed to .TRUE.
1646      * will check values for niter0 if debLevA, every timestep if debLevB
1647      * STOP in exf_check_range if 'out of range'
1648      * range chosen generous to allow for potential extema
1649      TBD: a version with stricter range
1650           permitted range would be runtime parameters
1651    o GMredi:
1652      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1653      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1654      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1655    o GCHEM:
1656      - move call to GCHEM_FORCING_SEP, so that it is now called before
1657        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1658      - introduced a useGCHEM runtime flag and applied it everywhere.
1659      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1660        this flag is now only visible within GCHEM-pkg routines.
1661      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1662        be replaced by a 3D array that is computed before thermodynamics; for
1663        this, the tracer ID iTracer had to be included into the parameter list
1664        of ptracers_forcing
1665      - set up forward_step to call gchem_forcing, that will replace
1666        gchem_forcing_int in ptracers_forcing
1667      - cleaning up
1668    o small cleaning of exch2: remove files that are also in eesupp/src
1669    
1670    checkpoint56
1671    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1672    o mnc: cleanup "full" files--fixes out-of-memory problem
1673    o ECCO-GODAE
1674      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1675      * fully merged and updated from SIO code
1676        windstress sign change affects
1677        - exf_inscal_[u/v]stress
1678        - sign of xx_tau[u/v] adjustments
1679        - signs in cost_scat
1680      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1681      * natl_box_adjoint updated and compressed
1682      * 2-level checkpoint switch added
1683        (tested in EXP. 1 of natl_box_adjoint)
1684      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1685    o SVD
1686      * first complete, non-hacked version for SVD calculations
1687      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1688        performed via direct access files admtlm_vector.it????
1689        (via ctrl_[un]pack)
1690      * optimcycle is used for ARPACK iteration counter
1691        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1692      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1693        and add linear transforms where necessary
1694      * controls are initial/final SST, SSS (can be extended; need to check
1695        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1696    o mdsio: filename info to both stderr, stdout
1697    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1698      from sign change
1699    
1700    checkpoint55j_post
1701    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1702      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1703    o add consistent build directories and .cvsignore files to verification
1704    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1705    o make all subroutines 30 or less characters in length for certain older
1706      compilers to work (a thorough search only turns up two routines in
1707      pkg/ptracers)
1708    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1709      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1710    
1711    checkpoint55i_post
1712    o change arrays for total vertical diffusivity (2.D if explicit,
1713      3.D if implicit) ; each ptracer uses its own background value.
1714    o added mnc/NetCDF output capability to ocn_compon_interf
1715      - added bits to verification/cpl_aim+ocn so that it can run on
1716        ITRDA and other clusters without the mpirun "-wd" option
1717    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1718      configuration
1719    o give MNC the ability to create additional files rather than
1720      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1721      - the default is just less than 2GB which is a practical limit
1722        on many systems
1723    o Compute the non-local term using either KPP vertical diffusivity (=default)
1724       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1725    
1726    checkpoint55h_post
1727    o add verification test "vermix"
1728    o remove all the *_ioinc flags and replace with the single global
1729      outputTypesInclusive flag
1730    o allow to set a vertical profile of vertical diffusivity for T & S
1731    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1732    o useMNC moved from data.mnc to data.pkg
1733    
1734    checkpoint55g_post
1735    o Renaming carbon AD experiments to comply with testreport conventions
1736    o Updating adjoint of Held-Suarez hs94.1x64x5
1737    o Fixing directives for non-ECCO forward_step, after ECCO directives
1738      have been fixed to avoid recomp. of do_oceanic_phys
1739      Works well for global_ocean.90x40x15,
1740      but recomp. issue remains for carbon
1741    o Updating adjoint output for natl_box_adjoint after
1742      pkg/ecco has been modified (see taga c55d_post)
1743    
1744    checkpoint55f_post
1745    o rename to timeave_init_fixed
1746    
1747    checkpoint55e_post
1748    o some delicate re-shuffle of store directives to avoid one
1749      extra call of do_oceanic_physics
1750      affects ecco_the_main_loop.F, do_oceanic_physics.F
1751      checkpoint_lev1_directives.h
1752    o NB: this may break global_ocean adjoint temporarily,
1753      but it is clear how to fix it. Will do later, need this now.
1754    
1755    checkpoint55d_post
1756    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1757    o ecco_cost_weights is modified to 1x1 runs
1758    o modifs to allow observations to be read in as
1759      single file or yearly files
1760    o enable to read exf forcing fields as either
1761      single file or yearly files (flag useExfYearlyFields)
1762    checkpoint55d_pre
1763    
1764    o switch between 2-level and 3-level checkpointing
1765    o add ability of MNC to write local and "partial" (eg. 2D slices where
1766      the full 3D field is never actually stored) arrays to NetCDF files
1767      with the correct (that is, the complete multi-dimensional) set of
1768      array indicies
1769      - used in mom_vecinv() to write the diagFreq output
1770      - tested (demonstrated) in verification/aim.5l_cs
1771    o further mnc-ification
1772      - add verification/lab_sea to the list with mnc setups
1773      - fix undefined mnc v-names in cd_code
1774      - add kpp to mnc output (both snapshot and timeave)
1775    o non-hydrostatic code
1776      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1777        in calc_gw.F
1778      - defaults to viscAh
1779      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1780        friction or Leith) in non-hydrostatic mode, as long as there is
1781        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1782    o pkg/cost
1783      extend simple cost functions to treat time mean quantities
1784      (T,U,V) via cost_accumulate_state from cost_tile
1785    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1786        be 2 times larger than the minimum size the advection scheme requires.
1787        now get a perfect conservation of salt in advect_cs test-exp (updated)
1788    o GGL90 (Gaspar's TKE mixed layer)
1789      - add horizontal diffusion of TKE, requires exchanges in
1790        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1791        default. In OPA there is no horizontal diffusion of TKE but the
1792        mixing coefficients are computed from a horizontal average of TKE of
1793        6 points or so. I think that diffusion has a little more physical
1794        justification.
1795      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1796        was in vain)
1797      - mask tke-variable in ggl90_init
1798    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1799    o fix biharmonic diffusion on CS-grid.
1800    o more obcs stuff
1801      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1802        for reading boundary values. This routine is called from
1803        obcs_prescribe_read
1804      - updated obcs_check
1805      - changed sponge layer relaxation parameter units for days to seconds
1806      - turned off sponge layer by default
1807      - changed argument list of OBCS_CALC to myTime+deltaTclock
1808      - fixed about 35 bugs in obcs_external_fields_load
1809    
1810    checkpoint55c_post
1811    o obcs stuff
1812      - new runtime flags useOBCSprescribe, useOBCSbalance
1813      - re-arranged obcs_calc
1814      - moved exf_getobcs to obcs_prescibe_read
1815        obcs_prescibe_read is called after ORLANSKI stuff
1816        and independent of it (executable can contain all).
1817      - updated obcs_check
1818      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1819        These may be necessary only if tangential velocities are
1820        prescribed at OB, not sure, needs testing.
1821    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1822      which simplifies the calls and passes the ifc check-bounds test
1823    
1824    checkpoint55b_post
1825    o add a 2D scalar, Z location, exchange_2 routine.
1826    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1827      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1828      affects advect_cs results (for the wrong reason): update output.txt
1829    o use a more standard discretization for biharmonic viscosity ;
1830     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1831      affects results of dome set-up: update output.txt
1832    o fix gad_advection.F (CubedSphere part), back to version 1.23
1833    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1834    
1835    checkpoint55a_post
1836    o merged code to
1837      * prescribe/read time-dependent open boundaries
1838        (works in conjunction with exf, cal)
1839      * sponge layer code for open boundaries
1840      * each boundary N/S/E/W now has its own CPP option
1841        (healthy for the adjoint)
1842    
1843    checkpoint55
1844    o up-to-date adjoint of previous breaks
1845      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1846      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1847      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1848      - carbon: * remove tr1-related adjoint verification
1849                * add ptracer as control variable
1850    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1851      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1852    
1853    checkpoint54f_post
1854    o in verification/carbin/ remove experiment related to
1855      ALLOW_PASSIVE_TRACER (array tr1 etc)
1856      code_ad/ input_ad/ results_ad
1857    
1858    o add two new packages
1859      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1860        + subject to optimization (memory)
1861      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1862        + subject to reordering (many GOTOs in the original code)
1863        + so far opps is called for every (i,j) point, and then operates in
1864          the vertical; one may want to reorder the scheme in order operate in
1865          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1866          fields)
1867    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1868      - all verification tests compile and run with linux_ia32_g77
1869      - defaults are compatible with current input files--nothing
1870        should change if you were not previously using MNC
1871      - MNC output has been added in numerous places (eg. timeave)
1872        but there are still a few writes not yet do-able with MNC
1873        (this is in progress)
1874      - flags now allow for either/or/both use of MDSIO and MNC and
1875        documentation will soon follow
1876      - numerous small formatting cleanups for ProTeX
1877    o add version info (via BUILD_INFO.h) to MNC and stdout
1878    
1879    checkpoint54e_post
1880    o add two new packages
1881      - pp81 (Packanowski and Philander, 1981), Richardson number and
1882        stratification dependent mixing
1883      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1884      - these scheme operate in a similar manner as KPP (without ghat, of
1885        course), however there is only one diffusivity that is used for both
1886        temperature and salinity (and passive tracers)ç
1887    o add offline package
1888    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1889      provided by Stephanie Dutkiewicz
1890    o genmake2: add ability to search for C compilers and cleanup test output
1891      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1892    
1893    checkpoint54d_post
1894    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1895    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1896      leading to additional shift by 5 days each year of integration
1897       (i.e. leading to considerable offset over the years)
1898    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1899    o start with no AB and no initial filtering (staggerTimeStep):
1900      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1901    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1902      (external loading & cpl import/export stay in forward_step.F)
1903    o update coupling interface to work with new staggerTimeStep
1904    o change MDSIO ptracers_pickup.
1905    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1906    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1907    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1908    
1909    checkpoint54c_post
1910    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1911      this affects (truncation error) output.txt of test-exp:
1912       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1913    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1914    o change Qnet to always be the net heat flux, (+upward).
1915      affects (truncation error) output of natl_box exp.: updated
1916    o define the max number of passive tracers in PTRACERS_SIZE.h
1917    o start to test mnc routinely in exp0
1918    o add sea-ice loading (sIceLoad) as a new forcing field.
1919    
1920    checkpoint54b_post
1921    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1922       impressive on Altix and Opteron systems)
1923    o diagnostics can now write NetCDF files through the mnc package
1924    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1925    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1926    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1927      affects (truncation error) output of lab_sea & natl_box exp.: updated
1928    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1929    
1930    checkpoint54a_post
1931    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1932    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1933    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1934    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1935      + internal_wave (shift in writing cg2d_ini_res)
1936    checkpoint54a_pre
1937    
1938    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1939      - modified verification/lab_sea and natl_box_adjoint accordingly
1940    
1941    checkpoint54
1942    checkpoint53g_post
1943    o prepare splitting of thermodynamics: store convect.counter in common block
1944    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
1945      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
1946    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
1947    o new parameter "nShapS": allow to treat differently S from T (nShapT)
1948    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
1949    o restore adjointability
1950    
1951    checkpoint53f_post
1952    o modifications that affect AIM experiment results (update output.txt):
1953      - no advection of S at top interface Nr (pkg/generic_advdiff)
1954      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
1955    o AIM pkg:
1956      - include stability function into surf.Flux derivative relative to Tsurf
1957      - calculate clear-sky radiation & surface temp. change (for diagnostics)
1958    
1959    checkpoint53e_post
1960    o merged cylindrical coord configuration
1961    o added rotating_tank experiment
1962    checkpoint53e_pre
1963    
1964    checkpoint53d_post
1965    o faulks upgraded: re-generate output.txt that have changed:
1966       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
1967    o Added Bryan and Lewis, 1979, vertical diffusivity profile
1968    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
1969    o added Sadourny discretization of Coriolis
1970      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
1971      - re-enabled use of omega3 (useAbsVorticity)
1972    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
1973      vector-invariant equations
1974      - note: does *NOT* yet use same variable visc. for no-slip BC's.
1975    o recoded the lateral boundary conditions for non-hydrostatic w, this time
1976      hopefully without new bugs
1977      - still to do: biharmonic friction for non-hydrostatic w
1978    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
1979    o regenerated output for global_ocean_ebm (using -ieee)
1980    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
1981      of mom_common/
1982      - simple re-arrangement of instructions within computing loop
1983    checkpoint53d_pre
1984    
1985    checkpoint53c_post
1986    o new version of coupler for AIM+thSIce and Ocean models
1987     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1988     - land: change Evaporation of snow
1989     - aim with thSIce: fix bug in snow-precip.
1990    o changes to calc_gw.F
1991     - bug fix for w^2 term near the bottom boundary
1992     - (hopefully) improve the lateral slip boundary condtions for use with
1993        partial/looped cells
1994      - because the bug fix changes two verification experiments anyway (exp5
1995        and plume on slope), change the lateral boundary condition from half slip
1996        to the value of no_slip_sides
1997    o ebm package wasnt quite up to the parallel task. Fixed that.
1998    o Adjoint of EBM package + verification
1999      * TLM OK
2000      * ADM not sufficient accuracy yet (needs further testing)
2001    
2002    checkpoint53b_post
2003    o Commiting new energy balance model to repository
2004      * package is pkg/ebm
2005      * verif. is verification/global_ocean_ebm
2006      * references are in ebm_driver.F
2007    C      * X. Wang, P. Stone and J. Marotzke, 1999:
2008    C        Global thermohaline circulation. Part I:
2009    C        Sensitivity to atmospheric moisture transport.
2010    C        J. Climate 12(1), 71-82
2011    C      * X. Wang, P. Stone and J. Marotzke, 1999:
2012    C        Global thermohaline circulation. Part II:
2013    C        Sensitivity with interactive transport.
2014    C        J. Climate 12(1), 83-91
2015    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
2016    C        Destabilization of the thermohaline circulation
2017    C        by atmospheric eddy transports.
2018    C        J. Climate 7(12), 1870-1882
2019    o Will need long integration testing.
2020    checkpoint53b_pre
2021    
2022    o created pkg/mom_common in preparation for variable viscosity code
2023    o renamed and split ini_mnc_io
2024    o pkg/land: only liquid water can diffuse or run-off
2025    o AIM using land: soil wetness availability account for snow
2026    o added printMapIncludesZeros to EEPARMS namelist
2027    
2028    checkpoint53a_post
2029    o restore TAMC compatiility for exf_constants.h
2030      (no usage of _d in .h)
2031    o Additional storing in KPP in an attempt to fix
2032      TAMC problem with adjoint of KPP code.
2033      (no success...)
2034      Identical code works fine with TAF.
2035    o Fixed verification/natl_box_adjoint experiments.
2036      Initial conditions for Experiments 4 and 5 are now
2037      set to "SEAICE_initialHEFF=0", which is more reasonable,
2038      and hence gives results closer to that of Experiment 2.
2039      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
2040    
2041    checkpoint53
2042    o stable checkpoint with up to date adjoint
2043      TLM tests only run for 1st grdchk at the moment. Its unclear if
2044      this is a code problem or a problem with resetting code for g_
2045      variables that is being autogenerated wrong.
2046      Otherwise:
2047       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
2048       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
2049         are both still in chaos following their security messes.
2050    
2051    checkpoint52n_post
2052    o various build (mostly genmake2) changes including:
2053      - ability to build/run more easily within Cygwin and MacOS X
2054      - more complicated Makefiles with a stronger dependence on Gnu Make
2055    o pkg/seaice modifications
2056      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
2057        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
2058        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
2059      - changed proxy for geostrophic velocity and updated
2060        verification/lab_sea/results/* accordingly
2061      - removed ADI dynamic solver from pkg/seaice
2062      - replaced all occurrences of 1/CSTICE or 1/CSUICE
2063        they caused a segmentation fault under certain circumstances
2064      - removed unused field WATR
2065    o bug fix in exf-package:
2066      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
2067         now reflect that.
2068    o small fixes in the cal-package:
2069      - set reference date to first of January for the 'model'-calendar
2070      - failing of cal_CheckDate in cal_FullDate now actually results in a
2071        warning
2072    o small modifications in exf-package to increase flexibility:
2073      - change climtempfreeze from a constant to a runtime parameter that
2074        is specified in data.exf_clim (default = -1.9)
2075      - introduce runtime parameter windstressmax (default = 2.0) that is
2076        specified in data.exf
2077    o fix in pkg/thsice:
2078      - update Evap (Tsf changes) to be consistent with Latent heat flux
2079      - maintain snow precipitation unchanged (even if Tsf >=0).
2080     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
2081    
2082    checkpoint52m_post
2083    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
2084      this does not change any of the results, because myIter=0 in swfrac always
2085      lead to jwtype=2 (the default anyway), but the call makes little sense
2086      as a default
2087    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
2088    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
2089      atmospheric model (AIM) to use it ; add a "slab ocean" component.
2090    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
2091    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
2092    o extending useSingleCpuIO option to work with new exch2 I/O format
2093      - old-style, missing-tile I/O is still accessible by defining CPP
2094        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
2095    o monitor package can write to NetCDF files and/or STDOUT
2096    o fix re-definition bug in MNC_GRID_INIT_ALL()
2097    o doc/api_reference added
2098      - a framework for building an API Reference Manual using all
2099        the "protex" comments embedded in the code
2100      - see pkg/generic_advdiff, pkg/mnc for examples
2101    o MNC:
2102      - make myThid the last argument for all subroutines
2103      - new default for the grid files: NO halos
2104      - add useMNC and other run-time flags
2105      - separate per-file-group handling of the unlimited dimension
2106      - early initialization of MNC w/ flags read at the eeboot stage
2107        and lookup tables set in initialize_fixed
2108      - write all MNC output to a freshly-created directory
2109    o thermodynamics sea-ice (thsice) is now tested with testreport.
2110    o test exp. advect_cs: use the standard cs32 grid ; update output.
2111    o Added functionality to grdchk:
2112      pick global i,j,k position (or nearest wet) where to perform check.
2113    
2114    checkpoint52l_post
2115    o new land formulation:
2116      a) use ground enthalpy as prognostic variable to ensure exact
2117         energy conservation.
2118      b) account for water temperature and for latent heat of freezing
2119         in all processes (rain, run-off, ground storage)
2120      c) compute surface and ground temperature implicitly.
2121    o aim_v23 modification for new land model:
2122      a) Treat separately land / ocean / sea-ice surface fluxes
2123         to allow implicit computation of land & sea-ice surface temp.
2124      b) add snow precipitation.
2125    checkpoint52l_pre
2126    
2127    o fix problem (when 1 tile is empty) in min/max monitor.
2128    o fix bug in timeAve (u,vZetatave in common block)
2129    o no restoring terms under ice for pkg/seaice
2130    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
2131    o bug fix for pkg/seaice pickups
2132    o change MNC call locations and add coordinate attributes
2133    o mask vorticity at the corner ; affects global_ocean.cs output
2134    o fix ini_curvilinear_grid ; test CS experiments with mpi
2135    o aim.5l_cs: modify sea-ice fraction input file ; update output
2136    o exf: Adding simple range check routine for exf fields after read
2137    
2138    checkpoint52k_post
2139    o removed top-level directory "diags"
2140      - we migrated these functions to pkg/timeave a long time ago
2141    o fixed bug introduced in pkg/monitor
2142    o accuracy ctrlprec = 32 insuffient for gradient checks using
2143      averaged fields (I/O via cost_averages)
2144      -> use ctrl.h in active_file*.F to control I/O precision.
2145    o paramter list of CALL ADTHE_MAIN_LOOP
2146    o added initial do_the_model_io to ecco
2147    o set all ...Freq to zero after cost_final
2148      taveFreq, dumpFreq, pChkptFreq
2149    o MAIN and ECCO differentiability restored
2150    
2151    checkpoint52j_post
2152    o fix nchklev in tamc.h for global_ocean...
2153    o Bringing flow and store directives up-to-date
2154    o Really weird thing!
2155      call do_the_model_io from the_main_loop with parameters
2156      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
2157      TAF places a faulty re-call of initialise_varia
2158      after cost_final call which should not be there!
2159    checkpoint52j_pre
2160    
2161    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
2162      error messages
2163    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
2164    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
2165      debug output
2166    o modfied mdsio_writefield.F to handle non-global files under exch2
2167    o update AIM Cubed-Sphere exp (aim.5l_cs):
2168      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
2169    o update AIM Equatorial Channel exp:
2170      use standard aim_v23 pkg and change the SST fields to be more realistic.
2171    o globalFile now works with exch2
2172    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
2173      mon_vort3.F to make exch2 friendly with >1 tile per cube face
2174    o limit timeave output for hi-res integrations
2175    
2176    checkpoint52i_post

2179    checkpoint52i_pre
2180    
2181    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
2182      the old pkg/aim).
2183    
2184    checkpoint52h_pre
2185    o shortened offending lines in exch2_send_rx?.template
2186    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
2187    o genmake2: add build & execute test for NetCDF code

2189      old grid files, moved CPP_EEMACROS.h to pkg/exch2
2190    o added useSingleCPUIO flag to monitor.F and mon_out.F
2191    o added temporary hack for sea-ice dynamics on the cube:
2192      metric terms are ignored and it is assumed that
2193      there is no sea-ice on cube faces 1, 2, 4, and 5.
2194    
2195    checkpoint52f_post
2196    o added exch2 cube routines to pkg/exch2
2197    o modified hs94.cs-32x32x5 to use it
2198    o added new grid files to hs94.cs-32x32x5
2199    checkpoint52f_pre
2200    
2201    checkpoint52e_post
2202    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
2203      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
2204    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
2205      to work with implicit vertical advection and AB ;
2206    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
2207    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
2208     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
2209    checkpoint52e_pre
2210    
2211    o fix bug in impldiff when Nr=1 or Nr=2.
2212    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
2213    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
2214    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
2215      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
2216    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
2217    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
2218    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
2219    
2220    checkpoint52d_post
2221    o re-tiled many expts to allow comparison in multi-processor mode
2222      - updated output accordingly
2223      - changed hs94.128x64x5 to use intial T from file rather than use the
2224        random number generator
2225    o add infrastructure in model routines for fizhi and gridalt packages
2226    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
2227    o changes to permit hi-res, cubed-sphere, configuration
2228      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
2229      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
2230      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
2231        of surface winds for the cube
2232      (A verification experiment, based on global_ocean.cs32x15, but with
2233       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
2234       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
2235       complete with example surface forcing files and matlab scripts to look
2236       at the output and compare it with that of global_ocean.cs32x15.)
2237    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
2238       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
2239       to conform to the common rule.
2240    o check-in the first version of the coupler + interfaces for multi-components
2241       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
2242       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
2243       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
2244       - ocean and atmos. share the same horizontal grid (no interpolation).
2245       - exchanges between component and coupler is done in forward_step
2246    o new verification experiment, cpl_aim+ocn:
2247       coupled ocean - AIM atmosphere on cs32 grid.
2248    
2249    checkpoint52d_pre
2250    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
2251    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
2252    
2253    checkpoint52c_post
2254    o Fixing OPTIONS files for use of exf:
2255      - ALLOW_ECCO not needed
2256      - ECCO_CPPOPTIONS.h should not be included from
2257        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
2258        as has been the case in the past
2259      - All cal/exf related options are currently set in
2260        single header file. Should remain so until we
2261        agree on a consistent new policy.
2262    o Removed all CPP options for cal package.
2263      cal has no more CPP options.
2264    o modified STOREs in GAD_ADVECTION
2265    o corrected key comp. for passkey
2266    
2267    checkpoint52b_post
2268    o new version: "thsice" of thermodynamic sea-ice pkg:
2269     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
2270     - modify fluxes but do not change theta directly;
2271     - light cleaning of bulk_force pkg (still needed with thsice).
2272     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
2273       + output_thsice.txt to test thsice & bulk_force pkgs.
2274    o put back grid & coriolis monitor output.
2275    checkpoint52b_pre
2276    
2277    o call "do_the_model_io" at the beginning (=> dump initial state)
2278    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
2279    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
2280      (need info on NUMBER_OF_PTRACERS)
2281    o missing PTRACERS headers in some routines
2282    o default tamc.h in pkg/autodiff supposed to crash
2283      to ensure proper customization
2284    
2285    checkpoint52a_post
2286    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
2287      - moved surfaceTendencyTice from pkg/seaice to main code
2288      - subroutine FREEZE_SURFACE now limits only surface temperature
2289        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
2290        => new output.txt for global_ocean.cs32x15 & global_with_exf
2291      - keep the old version of FREEZE for backward compatibility;
2292        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
2293      - corresponding modifs for TAF directives
2294    o added surface flux output variables to TIMEAVE_STATVARS

2298      but no warning issued by TAF
2299    
2300    checkpoint52a_pre
2301    o some bug fixes for #undef REAL4_IS_SLOW
2302    
2303    checkpoint52 = ecco_c52_e35
2304    o after testing adjoints of checkpoint51u_post
2305    
2306    checkpoint51u_post
2307    o this is the post-merge tag of the ecco-branch
2308      (needs another clean checkout and re-testing)
2309    o various natl_box_adjoint configs and results
2310      but no input fields
2311    o obcs adjoint not yet merged!
2312    o adding ECCO global 1x1 and 2x2 degree configs
2313    o updated/extended some store directives for seaice
2314    o pkg/ecco now containes ecco-specific part of cost function
2315    o top level routines the_main_loop, forward_step
2316      supersede those in model/src/
2317      previous input data.cost now in data.ecco
2318      (new namelist ecco_cost_nml)
2319    o in ctrl/ cleaned some cross-dependencies and updated CPP options
2320    
2321    checkpoint51t_post
2322    o this is the pre-merge tag of the ecco-branch
2323    
2324    checkpoint51s_post
2325    o cleanup: removed various obsolete #define-s
2326    o pkg/grdchk
2327      - renamed 'ph-grd 3' to 'grad-res'
2328      - merged from ecco-branch
2329        (remaining bug fixes for obcs gradient checks)
2330      - additional high-precision output for testreport
2331        (grep for 'precision_grdchk_result')
2332    
2333    checkpoint51r_post
2334    o cleaned up or removed CPP_OPTIONS.h files
2335    o updated results for some of the tests to reflect the new
2336      optfiles (-ieee: -O0 instead of -O3)
2337    
2338    checkpoint51q_post
2339    o cd_code:
2340      - moved cd_scheme.F -> cd_code_scheme.F
2341      - separate read_checkpoint from cd_code_ini_vars.F
2342      - separated cd_code part from write_checkpoint
2343      - updated AD_SOURCE, generated .flow
2344      - added CD_CODE_VARS.h to the_main_loop
2345      - Moving cd_code specific store dir.s to pkg/cd_code
2346    o ctrl package totally restructured
2347      - pack/unpack now optional and decoupled from
2348        xx_/adxx_ I/O
2349      - ctrl_pack/unpack cleaned
2350        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
2351      - confined inclusion of AD_CONFIG.h to where necessary.
2352    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
2353    
2354    checkpoint51p_post
2355    o create initial cd_code package
2356      - WARNING: the initialization of fields within packages
2357        is broken because INI_FIELDS (where READ_CHECKPOINT is
2358        called) is called *before* PACKAGES_INIT_VARIABLES.
2359        This seems to be backwards since
2360        1) its important to initially zero the entire field including
2361           the "halo" region
2362        2) zeroing needs to be done *before* reading pickup info
2363           and the pickup call might or might not happen in any
2364           particular run
2365      - this needs an overhaul for R2
2366    o cleanup verification/*/code/GMREDI_OPTIONS.h
2367    o cleanup testreport
2368    
2369    checkpoint51o_post

2377    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
2378    o bug fix in find_alpha.F for MDJWF:
2379      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
2380        change rho -> rho-rhoConst
2381      - replace call find_rho to find_rhonum

2383      and shifted to thermodynamics
2384    o removed PTRACERS.h in ptracers routine
2385    o added surfacetendencyPtr to S/R parameter list pracers_forcing

2397    
2398    checkpoint51n_post
2399    o modifications to make FREEZE flux visible to pkg/kpp
2400      - moved surfaceTendencyTice from pkg/seaice to main code
2401      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
2402      - subroutine FREEZE now limits only surface temperature
2403        (this means new output.txt for global_ocean.90x40x15,
2404         global_ocean.cs32x15, and global_with_exf)
2405    o added surface flux output variables to TIMEAVE_STATVARS
2406    
2407    checkpoint51n_pre
2408    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

2429    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
2430    o enable to apply restoring on S & T only in a latitude band.
2431    o update output (external_forcing_surf modif. change truncation errors)
2432       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
2433    
2434    checkpoint51k_post
2435    o change default to: useNHMTerms=.FALSE.
2436     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
