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

1634    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
1635      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1636        this flag is now only visible within GCHEM-pkg routines.
1637      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1638        be replaced by a 3D array that is computed before thermodynamics; for
1639        this, the tracer ID iTracer had to be included into the parameter list
1640        of ptracers_forcing
1641      - set up forward_step to call gchem_forcing, that will replace
1642        gchem_forcing_int in ptracers_forcing
1643      - cleaning up
1644  o small cleaning of exch2: remove files that are also in eesupp/src  o small cleaning of exch2: remove files that are also in eesupp/src
