5      ==============================      ==============================
6    
7    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
8    o lab_sea.hb87: modify the domain & update output.hb87.txt :
9      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
10      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
11      process. Fixed here by closing the domain at the Northern boundary.
12    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
13    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
14      a set of consecutive levels in/from a 3-D array.
15    o pkg/ptracers:
16      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
17      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
18    
19    checkpoint59j
20    o in pkgs: dic, obcs, offline, rbcs:
21      standard way to compute coeff. for time interpolation between 2 time reccords
22      which retains full precision (& make results less dependent on compiler).
23      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
24    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
25      packages instead of reading ice cover and wind speed separately
26    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
27     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
28      to allow to compile customized code before the update)
29    o cleaning-up:
30      - fix CPP instruction syntax in pkg/obcs
31      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
32        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
33      - fix some threads issue in IO parts.
34    o pkg/dic:
35      - add tons of "_d 0" (--> much better testreports !)
36       and then update outputs of tutorial_global_oce_biogeo
37    o pkg/mom_fluxform:
38      add a special version of momentum advection intended to conserve momentum
39      next to a bathymetry step or a coastline edge. (default = off = #undef)
40    o new read/write pickup version:
41      - for now, only implemented for main (mdsio) pickup file.
42      - write out only what is needed to restart; merge pickup_nh , pickup_ph
43        and main pickup together.
44      - read meta file; read only what is needed to restart; stop if a field
45        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
46        if it make sense (even if the restart is not perfect).
47      - if no meta file, assume that pickup to read corresponds exactly to
48        a pickup that would currently be written.
49      - read pickup written in the old format (until checkpoint59i) if it
50        recognizes an old meta file (no field-list).
51      - add a meta file in exp. which starts from a pickup: 2 cases:
52        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
53         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
54        b) a meta file describing the content of the associated pickup file
55         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
56    o pkg/mdsio & pkg/rw:
57      - new routine to read a meta file ; new set of routine to read
58        Multiple-fields file (with meta file).
59    o added open boundary conditions capability for seaice
60        HSNOW, HSALT, UICE, and VICE
61    
62    checkpoint59i
63    o adjoint:
64      * fix multiDimAdvection adjoint
65        (partial recomputation problem by TAF for fVerT(:,:,kDown)
66        and comlev1 size definition (maxpass vs. max. number of tracers)
67      * verification/global_ocean.90x45x15 adjoint now tests
68        NLFS and multiDimAdvection using DST3 (=30)
69      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
70    o pkg/kpp: add "_d 0" to real constant (if missing);
71      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
72      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
73    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
74      for internal parameters related to restart process (formerly from PARAMS.h)
75      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
76    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
77      as argument. (only atm2d & obcs write_pickup have not yet been updated)
78    o pkg/monitor:
79      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
80      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
81      - account for deep Atmosphere factor and density factor (anelastic)
82    o added open boundary conditions capability for seaice HEFF and AREA
83    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
84      thermodynamics
85      - requires a little reorganization, which affects the testreport results
86        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
87        so that now the conservative form is tested
88      - add a few comments
89    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
90    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
91    o add new diagnostics to seaice: advective, diffusive fluxes (only for
92      multidim-advection, for scheme 2 they are not filled) and transports,
93      thermodynamic growth rates
94    o change units of EmPmR (inside the code, + within coupling interface)
95      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
96      Affects results @ truncation level (cg2d match) and update output of
97       experiments: lab_sea(6), global_ocean.90x40x15(10),
98      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
99      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
100      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
101      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
102    
103    checkpoint59h
104    o pkg/exf:
105      - improve vectorization by moving if-statement out of loops in
106        exf_mapfields, exf_radiation
107      - exf_bulkformulae.F: introduce 2D fields and vectorize code
108    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
109    o testreport:
110      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
111        monitor & update offline_exf_seaice exp. output.
112      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
113    o pkg/seaice:
114      - bug fix in the evp solver: boundary conditions were affected be
115        masking of zMax/zMin (changes results)
116      - minor bug fix in boundary conditions in seaice_calc_strainrates
117        (changes results for no_slip)
118      - seaice_lsr.F: make interpolation of eta dependent on boundaries
119      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
120      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
121        stress formulation and no-slip boundary conditions
122    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
123      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
124    o pkg/seaice: a first HSALT time stepping equation has been checked in
125    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
126      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
127      without requiring DO-IF statements
128    o pkg/thsice:
129      use continuous power-law function for partition of energy between lateral
130      melting/freezing and thinning/thickening ; old code using step function
131      still available with #undef THSICE_FRACEN_POWERLAW
132      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
133    o testreport: change AD testing : check against results/output_adm.txt
134      using same scripts as for forward test.
135    
136    checkpoint59g
137    o adjoint testing: in preparation for changing testreport:
138      - output format: cost and grad written on separated lines
139      - ad output results in directory "results" (instead of "results_ad")
140    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
141    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
142    o pkg/ecco: allow user defined cost function contributions
143    o testreport:
144      Allow to choose (per experiment) the list of tested output variables
145       and the main variable (used to issue a pass/FAIL ) ;
146      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
147      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
148      Also modify printing of summary:
149       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
150       b) echo the list of tested variables in the individual summary.txt of
151          each experiment.
152    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
153      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
154      (but still depend on the tile decompostion of the domain).
155    o pkg/seaice: change a discretization detail to make the B-grid code
156      "more symmetric". This change is likely to remove all "ridges/leads" that
157      where quasi-aligned with the grid in B-grid solutions. It may also be
158      the solution to the stress coupling issues with the B-grid.
159    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
160      remove .cvsignore from input dir. (since testreport no longer run here).
161    o pkg/thsice:
162     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
163     - fix reshaping of sea-ice just after advection:
164       melt all the ice only if ice-volume is too small.
165     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
166       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
167     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
168    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
169      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
170    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
171      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
172      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
173      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
174      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
175      -> update output.txt
176    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
177     this affects truncation error: -> update output.txt of exp:
178      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
179      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
180    
181    checkpoint59f
182    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
183    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
184      a bounded range (in forward mode)
185    o pkg/ecco, ctrl, autodiff and mom_common:
186     internal parameter controls, completements of implementations
187    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
188    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
189      (not seem any difference in testing results).
190    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
191       at face corners.
192    o pkg/generic_advdiff:
193     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
194      loop range indices for computing vertical advection tendency
195      and do the calculation in the interior only (no overlap) ;
196      for now, only implemented for SOM advection (to save CPU time).
197     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
198    o exch2 adjoint
199      First set of changes:
200      - add exch2 hand-written adjoint templates
201      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
202        This will require cleanup in pkg/autodiff/*.F
203        (changed routines currently kept separate in verif. code/)
204      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
205        that used to hide exch2 or cubed-sphere specific code
206        (commented via 'cph-exch2')
207    o pkg/seaice
208      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
209    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
210       output of global_ocean.cs32x15.thsice .
211    
212    checkpoint59e
213    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
214      for B-grid vector (not yet tested) and C-grid vector (<- only used
215      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
216    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
217      (#ifdef ALLOW_SALT_PLUME)
218    o gather_2d/scatter_2d: removed halo regions
219    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
220      scheme and the corresponding test case (under front_relax dir). For now,
221      only available with Skew-flux form and not yet tested in realistic set-up.
222      adjoint: store directives updated, but gradient checks deteriorated,
223      so maybe GM/Redi adjoint is now broken.
224    o seaice adjoint
225      * add AREA, HEFF, HSNOW as control variable
226        (should not change lab_sea results)
227      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
228    o pkg/seaice:
229      * added computation of saltFlux in seaice_growth;
230        For time being, sea ice salinity is assumed constant
231        contribution of snow flooding to freshening of sea ice is neglected.
232        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
233        defaults to 0.0 in order to maintain backward compatibility.
234        Typical values for SEAICE_salinity are 4 to 10 g/kg.
235      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
236      * added SEAICE_availHeatFrac, which specifies fraction of surface level
237        heat content used to melt or grow ice
238      * commented out cap of HICE: it helps keep ice thinner
239      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
240      * applied OBCS T/S mask to HEFFM sea ice mask
241    
242    checkpoint59d
243    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
244     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
245     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
246    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
247     and change default value of parameter "GM_Small_Number";
248     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
249       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
250       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
251    o pkg/ecco: cost function when applying pkg/smooth to controls
252    o pkg/ctrl: add forcingPrecond run time parameter
253    o pkg/seaice:
254     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
255     - fix bug in metric terms of u-equation in LSR solver (implicit part),
256       changes verification/lab_sea
257     - rearrange implicit part of u-equation in LSR solver to make it easier to
258       read, understand, and debug. This causes changes at the truncation level.
259     - fix (serious) bug in the boundary conditions (sign error in the implicit
260       part) of the LSR solver. Changes all LSR results.
261     - fixed problem with HSNOW initialization to avoid thick snow when AREA
262       is initilized with small values - does not change lab_sea results.
263     - added HsnowFile initialization capability
264    o pkg/smooth: addition to model/src and pkg/ctrl so allow
265     initialization of pkg/smooth and application to control vector
266    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
267    o dependencies: pkg/profiles requires pkg/cal
268    o pkg/profiles:
269     - added option ALLOW_PROFILES_GENERICGRID
270         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
271         that interpolation information (grid points and coefficients) is provided
272         within the netcdf input files.
273         -> sample matlab scripts can be found in MITgcm_contrib/gael
274         that allow you to prepare netcdf input files.
275     - also modified: cleaner include statements, cleaner error print statements,
276       cleaner stops when error, and more tests of the netcdf input files consistency.
277    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
278    o pkg/seaice:
279     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
280       requires a new routine: seaice_diagnostics_fill.F
281     - make sure that seaice does not move if not forced (pressure replacement
282       method, Hibler and Ip, 1995), changes results
283     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
284     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
285       It is turned off by default (=-1.), because it changes the results.
286     - make it possible to read AREA from a file, too.
287    
288    checkpoint59c
289    o add S/R and diagnostics for oceanic mixed-layer depth
290    o move GMRedi call after all vertical mixing schemes (including KPP)
291    o pkg/thsice:
292     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
293      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
294    o pkg/obcs:
295     - bug fix for balance code
296    o pkg/seaice:
297      - allow values of SEAICE_elasticParm > 1
298      - add new parameter SEAICE_evpTauRelax as an alternative
299        to SEAICE_elasticParm
300      - make lsr boundary conditions free slip (by default), changes result
301      - add code for no slip boundary conditions for lsr
302      - set minimum of zeta to zero (and not 4e8) (changes results)
303      - add a cap on AREA after advecting AREA if seaice_growth is not called
304    o change calculation of Visbeck K:
305      - no longer depend on tapering scheme; instead, compute slope (limited
306        by GM_maxSlope). this is equivalent to what was comuted before with
307        clipping or linear tappering.
308      - fix vertical averaging (wrong by 1/2 level)
309      - leave the old version (but will not be maintained) within
310        #ifdef OLD_VISBECK_CALC / #endif
311      - update output of exp. ideal_2D_oce
312    o change error catch in calc_r_star to improve vectorization
313    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
314      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
315    o adjoint:
316      Re-organized adjoint checkpointing according to Matt Mazloff
317      (but with modifs/completions/cleanups)
318      Storing is now bundled into large arrays to optimized I/O
319      (and second step in cleanup of the_main_loop)
320    
321    checkpoint59b
322    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
323      - export/import (between ocean & coupler) fields needed for ocean DIC.
324    o pkg/seaice:
325      - get rid of three more exchanges seaice_calc_viscosities (required
326        different loop boundaries in seaice_lsr and seaice_ocean_stress)
327      - bug fix in seaice_ocean_stress (update of lab_sea required)
328      - reduce loop boundaries to necessary minimum also in seaice_evp
329      - go back to the old way of computing deltaC/Z as the adjoint likes that
330        better
331    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
332      passive tracer to an Age Tracer) + update output.txt
333    o pkg/exf:
334      - implement A-grid / C-grid selection for wind-stress input files.
335      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
336      for now, in exf_bulk_largeyeager04.F only :
337      - change implementation for case where windspeed + 2. components wind-stress
338        are read-in. AND use rhoConstFresh to convert evap.
339    o pkg/seaice:
340      - use correct EXCH_UV for wind-forcing (on A-grid).
341      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
342        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
343    o pkg/exf:
344      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
345      EXF_INTERPOLATION:
346      - merge global_with_exf/code version of exf_interp_read.F
347        to the main code ;
348      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
349        reading the file ; Important: This options needs to be defined to recover
350        previous code.
351        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
352      - no longer loose real*8 precision along the way when using exf_iprec=64.
353    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
354      - change discretisation of evp-solver in order to avoid another exchange
355        (changes lab_sea) and clean up a little
356      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
357        help the adjoint (this also changes the results slightly)
358      - add a few "_d 0" where they had been missing in seaice_evp.F
359      - cleaning up: remove unused seaice_calc_rhs.F
360    o pkg/exf: some cleaning-up:
361      - change various "constants" into runtime parameters
362      - cleaned-up Large&Yeager04 routine which should eventually
363        replace exf_bulkformulae.F (changed names of S/R and CPP)
364        and merged various ALLOW_ATM_WIND options
365     only used with thsice pkg (in thsice_get_exf.F):
366      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
367        which are used when useStabilityFct_overIce=TRUE (= the default)
368      - change default values of ice & snow emissivity and scale downward LW
369        by ice & snow emissivity.
370    o pkg/thsice:
371     fix few little problems, in thsice_calc_thickn.F:
372      - growth vertically (and not laterally) if iceFrac == iceMaskMax
373      - melt only laterally if hIce < hThinIce (as the comments say)
374      and in thsice_extend.F:
375      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
376      - start to form ice as soon as the minimum ice-volume is reachable.
377     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
378      and cpl_aim+ocn
379    o pkg/kpp
380     - move computation of surface related input fields to KPP into a new
381       subroutine kpp_forcing_surf.F
382     - remove wrong (within bi,bj loops) EXCH calls.
383     - little cleaning (add argument myThid in last position, cvs header ...)
384     - for now, fix conservation problem by exchanging KPPviscAz (may not
385       be the best fix)
386    o pkg/seaice
387     - check for inconsistent evp parameter/cpp-flag combination
388     - remove leftover errIO flat for obsolete name list error handling
389    o OpenAD
390     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
391    
392    checkpoint59a
393    o pkg/seaice: some parameter clarifications and a little bit of clean up
394    o pkg/thsice: rename run-time parameters:
395       himin       -> hIceMin
396       himin0      -> hThinIce
397       hihig       -> hThickIce
398       i0          -> i0swFrac
399       transCoef   -> bMeltCoef
400       frac_energy -> fracMelting
401      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
402       with default values (for now) that do not change the results.
403      remove old version of thsice vars advection in pkg/seaice.
404    o in FFIELDS.h:
405      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
406      - make pLoad & sIceLoad always available (but still only used if
407         ATMOSPHERIC_LOADING is #define).
408    o pkg/kpp: replaced _KPP_RL with _RL
409    o bug fixes for vertical diffusivity computations when both KPP and
410        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
411        are no longer updating the vertical diffusivity array
412        (passed as argument) but are (re-) setting those arrays.
413    o pkg/seaice: fix bug in evp solver, while doing that
414      - change (improve?) discretization of stress computations for both
415        cgrid-lsr and evp solver
416      - add a new routine to compute strain rates
417      - the above changes lab_sea results
418      - add no slip conditions for evp solver (off by default), lsr-version
419        may follow
420      - fix exchange for shear at Z-points (does not change lab_sea)
421      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
422        (to force the user to pick a time step since there is not "safe" way
423        of choosing it)
424      - add principal stress diagnostics
425      - rearrange fields for evp a little to avoid having to call a: too many
426        exchanges and b: exchanges for stress trensor components which we do
427        not have.
428      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
429        of evp, complete rewrite for lsr case (latter is does not yet work
430        in all cases)
431    o pkg/kpp: add code to have mixing in shelf ice caverns
432      - add myThid to all kpp routines (long overdue)
433    
434    checkpoint59
435    o pkg/exf:
436      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
437        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
438      - move exf header files from lower_case.h to UPPER_CASE.h ;
439        add missing cvs Header & Name
440      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
441      - add namelist param. selectStressGridPosition, exf_monFreq
442      - retire many _CLIM routines, and remove data.exf_clim
443        + params moved to data.exf
444        + climsst, climsss now handled by exf_set_gen, i.e.
445          climss?period=0 refers to constant field,
446          climss?period=-12 to monthly forcing
447      - split up namelists in data.exf
448    o pkg/seaice:
449      - remove seaice_exch and seaice_exch_uv
450      - remove superfluous exchange of theta
451      - add myThid to seaice_budget_ocean/ice
452      - add new interface for atmospheric wind forcing (C-grid only)
453        + new routine
454        + two new field (taux, tauy for stress over ice)
455        + removed one global field (DAIRN) for C-grid case only
456    o pkg/thsise
457      - 2nd set of modifs for thsice adjoint in conjunction with exf
458    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
459    
460    checkpoint58y_post
461    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
462      vertical diffusivity, similar to that in MOM4; turned on using
463      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
464      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
465    o Added capability for 3D specification of background vertical diffusion
466      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
467      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
468      "data" file that contains the 3D vertical diffusivity coefficients.
469    o ice dynamics (pkg/seaice) with thsice thermodynamics:
470      - add code within pkg thsice to advect & diffuse sea-ice fields
471      similar to (and will replace) what has been added in  seaice_advdiff.F,
472      but: - conserving Mass, Heat & Salt.
473           - better when using non-linear advection scheme (not yet fully tested)
474           - can also be used in atmospheric set-up (for now, only the diffusion).
475    
476    checkpoint58x_post
477    o IO option for global-file compact format:
478      - add options when generating topology (utils/exch2/matlab-topology-generator)
479      - add I/O capability (pkg/mdsio).
480      - adapt utils/matlab/rdmds.m to read this format.
481      for now long-line format not yet supported by pkg/mdsio (& exch2).
482    o shelfice: add a few diagnostics
483    
484    checkpoint58w_post
485    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
486      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
487      (and replace horiVertRatio in NH code).
488      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
489                         and tutorial_plume_on_slope (sensitive to truncation)
490    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
491      directly to drive seaice model (C-grid only)
492    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
493     - reintroduce computation of wind from stress,
494     - compute tau (in exf_bulkformulae.F) from windstress averaged to
495       mass points to avoid tau = 0
496     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
497    o rdmnc.m: make it work with "global" files created with gluemnc
498    o rdmnc.m : some improvements in dealing with singleton dimension
499      (tested on all testreport mnc output files).
500    o genmake2: disable pkg/profiles if netcdf test fails.
501    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
502    o move call to cal_readparms up to make calendar parameters/variable available
503      to all packages
504    
505    checkpoint58v_post
506    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
507      useDynP_inEos_Zc tested.
508    o pkg/exf: changes to properly interpolate/mask/scale initial fields
509    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
510      and portions thereof.  See read_cs.txt for description and examples.
511    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
512      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
513      following the great-circle arc between those 2 points.
514    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
515      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
516    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
517     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
518     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
519     - still needs work (not working with some options ; efficiency to improve)
520       and serious testing.
521     - use this scheme for temperature & salinity in 2 advection test exp.:
522       advect_xy & advect_xz, respectively.
523    
524    checkpoint58u_post
525    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
526    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
527    o testreport: add option "-skipdir" to skip some test.
528    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
529      momentum calculation.
530    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
531    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
532      remove checkpoint.F and the_correction_step.F (no longer used);
533      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
534    o add option (linFSConserveTr) to correct for tracer source/sink due to
535      Linear Free surface
536    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
537    o pkg/thsice: fix reading mnc-pickups
538    
539    checkpoint58t_post
540    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
541    o pkg/mdsio:
542     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
543       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
544       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
545     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
546     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
547       either MDS_READ_FIELD or MDS_WRITE_FIELD )
548     - new S/R (to replace MDSWRITEMETA), which allows to write more
549       informations (variable names, time ...) to meta files.
550     - modify rdmds.m to give back the meta file content.
551    o pkg/diagnostics: change vertical interpolation to be safer, and more
552       flexible (define p-levels to interpolate to in data.diagnostics);
553      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
554       diagnostic pointer.
555    o pkg/seaice: more cleaning up of seaice_growth, added many comments
556    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
557    o fix multi-category seaice:
558     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
559       SEAICE_MULTICATEGORY
560     - fix short wave heat flux
561    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
562       and allow to use EVP solver. Change forward lab_sea: test both EVP
563       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
564    o Initial check-in of lab_sea adjoint
565      (very similar to natl_box_adjoint/code_seaice)
566      * used C-grid and EVP solver
567      * used KPP, GM/Redi
568      * uses inAdExact=.TRUE.
569      * gradient checks fail for both ADM and TLM
570        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
571        f.d. gradients actually seem more problematic than ADM, TLM gradients;
572        issue is related to forward mismatch between g77 an ifort
573    o pkg/seaice: overhaul of thermodynamics
574     - growth.F and groatb.F are replaced by new routine seaice_growth.F
575     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
576     - move a few global fields out of SEAICE.h into seaice_growth.F and
577       make them 2D (FICE/QNETO/ ...)
578     - remove FO (it is the same as QNETO)
579     - introduce a few local fields to avoid modifying external fields such
580       as atemp, etc.
581    
582    checkpoint58s_post
583    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
584      changed exf_set_gen.F so that
585        genperiod=0 means input file is one time-constant field and
586        genperiod=-12 means input file contains 12 monthly means
587    o CG2D: use pre-computed solver main-diagonal (stored in common block);
588      this affects truncation error ; generate new output file for exp. which
589      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
590        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
591        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
592        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
593        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
594        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
595    o start implementation of deep-atmosphere and anelastic formulation
596    o verification: remove 2nd copy of input files and use script "prepare_run"
597      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
598    o mom_common/vecinv/fluxform: fix a few initialisation isssues
599    o profiles: fix for multithreaded case
600    
601    o diagnostics: rename few diags:
602      s/'PRESSURE'/'RCENTER '/g
603      s/'TICE    '/'oceFreez'/g
604      s/'TAUX    '/'oceTAUX '/g
605      s/'TAUY    '/'oceTAUY '/g
606      s/'SWFLUX  '/'oceQsw  '/g
607      s/DIFx/DFxE/g
608      s/DIFy/DFyE/g
609      and add few ocean-forcing diagnostics:
610      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
611    o modifications to pkg/seaice/growth.F and budget.F, which change results of
612      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
613      as actual snow thickness.  It now refers everywhere to effective snow
614      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
615    
616    checkpoint58r_post
617    o modifications to pkg/seaice/growth.F, which change results of
618      lab_sea experiment: fixes pertain to melting snow over open water, to
619      masking EVAP under sea ice, and to using the correct AREA variable for
620      computations of EVAP, PRECIP, HSNOW, and GHEFF
621    o add ability to read bathy, salt, and theta using MNC (off by def)
622    o add flooding algorithm and advection of HSNOW for pkg/seaice;
623      both are turned off by default and do no change any results
624    o seaice advection with pkg/thsice: a step toward the use of non-linear
625      advection scheme, but #ifdef or commented out for now (requires more EXCH).
626    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
627      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
628      in natl_box (affects results @ truncation level: update output.txt)
629    o multi-threading and IO:
630      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
631      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
632        (needed to work with SingleCpuIO): tested in all verif. exp.
633    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
634      affects the results (but none of the verification test uses this scheme).
635    o Adding some pkg/diagnostics capability to pkg/seaice
636      (will certainly be subject to changes)
637    o ctrl: adding new control variables:
638      lwflux, lwdown, evap, snowprecip, apressure, runoff
639    
640    checkpoint58q_post
641    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
642      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
643      high_res_cube configuration by 4% on Columbia.
644    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
645      add (in global_with_exf/code) a version of EXF_INTERP_READ without
646      dynamical allocation (seems to work in multi-threaded).
647    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
648      single CPU io) so that TAF does not have to see EESUPPORT.h
649    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
650    
651    checkpoint58p_post
652    o obcs: stop if obcs is used with useCDscheme = .true.
653    o shelfice:
654     - fix a sign error so that no slip at shelfice interface works
655     - remove stop for combination non-hydrostatic code and shelfice. That does
656       not mean, that the results are correct, but at least they are numerically
657       stable
658    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
659    o added adjoint exch routined for all exch*3d* routines
660      and updated flow directives
661    
662    checkpoint58o_post
663    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
664      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
665    o change controling S/R for writing pickup file (new S/R do_write_pickup)
666      and clean-up reading/writing of pickup files.
667    o fix local version of read/write pickup (NH part) in rotating_tank/code
668    o simplify EXCH interface:
669     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
670     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
671    o added the regrid package
672    o shelfice:
673     - add a simple boundary layer scheme to reduce noise
674     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
675    
676    checkpoint58n_post
677    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
678       local variable (not in common block).
679    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
680      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
681      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
682        to work with SingleCpuIO.
683    o add "_d 0" to real constant of pkg/cfc subroutines ;
684       update exp. cfc_exemple & tutorial_cfc_offline output files.
685    o multi-threading and IO:
686      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
687        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
688      - barrier before and after reading.
689      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
690      - avoid using MDS_WRITELOCAL for LAND pkg output.
691      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
692        common-block variables ; Allows multi-threading with master-thread IO.
693    o change default MAX_NO_THREADS from 32 to 4 ;
694      and stop cleanly when MAX_NO_THREADS is too small.
695    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
696    
697    checkpoint58m_post
698    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
699       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
700    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
701       keep global_ocean.90x40x15 (for AD testing) with former secondary test
702       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
703    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
704        add MITgcm_tutorials (= code + all the tutorials)
705    o ecco, option to compute cost for total ssh (mean+anom)
706    o consistent with addition of ptracer and ssh in pkg/profiles
707    o profiles: adding ptracer and ssh
708    o testreport: change multi-test output-file name
709      (from output.txt.{name} to output.{name}.txt)
710    o profiles: now ok for mutli-tiles case
711    o seaice: add 4 parameters for different advection schemes for area,
712      (effective) seaice thickness, enthalphy, and snow height. Their default
713      is the standard parameter SEAICEadvScheme
714    o calc_gw:
715     - add cosFacU in zonal viscous flux (harmonic.visc.).
716     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
717       of tutorial_plume_on_slope.
718    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
719    o calc_gw: true flux-form, account for horizontal grid spacing.
720      update rotating_tank results, but not plume_on_slope (affected at
721      truncation level, 11 digits).
722    
723    checkpoint58l_post
724    o calc_gw:
725     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
726     - remove side-drag for now (need to fix it); update plume_on_slope results.
727     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
728    o commit code to make SST/SSS weights spatially variable
729      (based on either variable in-situ or variable initial T/S weights)
730    o pkg/ecco:
731      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
732        now based on horizontally varying weights wthetaLev, wsaltLev
733      * cost_averagesflags now returns year indices in addition to day, month
734      * sflux balance is performed on annual basis
735        (sflxumm, sfluxmm2, bal_sfluxmm)
736      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
737        including separate counting and multipliers
738    o pkg/rbcs
739      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
740    
741    checkpoint58k_post
742    o testreport:
743     - always build in dir. "build" (if not there, mkdir build instead of building
744       & running in input)
745     - run in dir run (if it exists), in build otherwise.
746     - call prepare_run (if input/prepare_run exists)
747     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
748    o pkg/exf modifications to interpolation and rotation routines for more
749       reasonable treatment of North Pole singularity: for tracers North Pole
750       value is set to northernmost zonal-mean value, for zonal velocity it is
751       set to zero, and for meridional velocity it is set to northernmost value.
752    o pkg/exf/exf_check_range.F
753     - add tile index to diagnostics and move stop statement to the very
754       end of the routine.
755    o pkg/diagnostics: (diagnostics_main_init.F)
756      define title of isomorphic variables according to the current config.
757    o pkg/thsice with pkg/seaice dynamics:
758    - fix domain of computation (interior only, required for exf) and do exchanges
759    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
760    o towards a standard way of dealing with multi-threading in MONITOR
761      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
762    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
763       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
764    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
765    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
766    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
767       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
768    o tracer advection:
769     - clean-up and simplify calc_common_factors.F
770     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
771       advection subroutine (but still not used within DST advection S/R)
772    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
773    
774    checkpoint58j_post
775    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
776      from file (collects calls previously in FORWARD_STEP)
777    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
778    o adjoint store dir. adjusted accordingly
779    o genmake2
780      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
781    
782    checkpoint58i_post
783    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
784      on wind stress (SEAICEstressFactor defaults to 1.)
785    o Total number of Timers is finite (<=40): comment out 2 non-essential one
786      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
787    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
788      on CS-grid: no longer loosing mass.
789    o exf & curvilinear-grid: no longer modify longitude xC & xG.
790    o pkg/ggl90: fix sloppy output and fix a bug
791    o pkg/seaice: added SEAICEuseEVPpickup parameter
792      - Set to false in order to start EVP solver with
793        non-EVP pickup files when using SEAICEuseEVP
794      - fix sign error in diffusion in seaice_calc_rhs
795    
796    checkpoint58h_post
797    * Modifications for bottom topography control
798      o replace hFacC by _hFacC at various places
799      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
800      o add non-self-adjoint cg2d_nsa
801      o update autodiff support routines
802      o re-initialise hfac after ctrl_depth_ini
803      o works for 5x5 box, doesnt work for global_ocean.90x40x15
804    * Adding verification for 5x5 box (4-layer) bottom topography control
805    
806    checkpoint58g_post
807    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
808       used for mean seasonal cycle, mean diurnal cycle); add an example
809       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
810    o pkg/ggl90:
811      - add parameter (minimum surface kinetic energy)
812      - fix bug (avoiding division by zero)
813    o couple pkg/thsice to pkg/seaice:
814      - modify advection in seaice to accomodate new scalar fields to be advected
815      - only muliDimAdection scheme work with seaice/thsice
816      - mapping of thsice-variables to seaice-variables, back and forth
817      - does not break the verification experiments, but does not give the
818        desired results either
819    o pkg/seaice
820      - make (default) second order advection a bit less confusing?
821    
822    checkpoint58f_post
823    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
824      to pkg/seaice):
825      - new routines thsice_map_exf and thsice_get_exf provide the interface
826      - add an additional formal parameter to thsice_solve4temp
827    o pkg/exf:
828      - add new fields wspeed, snowprecip (to be able to couple to thsice)
829      - correct Stefan-Boltzmann constant
830      - new parameter for longwave surface emittance
831      - separate some stuff from exf_bulkformulae into new routines  
832        exf_radiation, exf_wind
833      - add new parameters and constants: longwave emissivity for ocean, ice
834        and snow, evaporation parameters over ice
835      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
836        either wind from stress or stress from wind
837    o pkg/thSIce:
838    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
839    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
840       and THSICE_CALC_THICKN
841    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
842    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
843      to make debugging easier.
844    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
845    o pkg/bulk_force:
846      - clean-up comments and parameters ;
847      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
848    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
849      generate new output for test-experiment: aim.5l_cs.thSI
850    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
851      testreport accordingly
852    
853    checkpoint58e_post
854    o SEAICE_CGRID adjoint done
855    o R_STAR adjoint implemented.
856      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
857      * need to sort out init. of h0facc, etc.
858    o Make pkg/profile fully independent of ecco,cost, etc. stuff
859      to be able to use it in pure forward.
860    
861    checkpoint58d_post
862    o upgrade simple test-experiment to tutorial example:
863     step.1: duplicate the experiment and (step.2) will remove the old copy.
864      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
865      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
866      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
867      tutorial_global_oce_biogeo    <- copy of dic_example
868      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
869      tutorial_plume_on_slope       <- copy of plume_on_slope
870      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
871      tutorial_global_oce_optim     <- empty for now (David ?)
872      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
873     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
874    o correct a sign problem in cost_scat.F
875    o obcs and ptracers: fix boundary conditions for advections schemes
876      with larger stencil
877    o thsice adjoint: start
878    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
879      completeness
880    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
881      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
882    o ptracers adjoint:
883      * avoid extensive recomputatations
884      * fix missing re-init. of gptr (missed by TAF)
885    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
886      me to turn off the excessive output to STDOUT that this package produces
887    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
888      and add those terms in Vector-Invariant formulation.
889    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
890      if the control period (xx_hfluxperiod etc) is 0
891    o in profiles pkg, clean routines and fix details
892    o in ecco pkg, reading ssh data:
893      fix problem in case the model does not start at iter0=0
894    o fix mnc-pickup/restart for ptracers
895    o new package prifiles:
896      code to compute profile-based cost by Gael Forget
897      (modifs in ecco, ctrl, autodiff)
898    o Benign bug fix in initialization (spotted by M. Mazloff) of
899      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
900    
901    checkpoint58c_post
902    o adjoint: finish NLFS adjoint and provide reference output in
903      verification/global_ocean.90x40x15/results_ad_nlfs
904    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
905      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
906      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
907      with SEAICE_CGRID defined.
908    o move calendarDumps from "data" to "data.cal" and clean-up the code
909      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
910    o add useEXF & useCAL flags (for now, set in hard-coded way)
911    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
912      (were missing in NH mode, and wrong in quasihydrostatic mode).
913      waiting for Chris updated version of calc_gw to add those CALLs.
914    o fix bug in quasihydrostatic S/R ;
915      add a test for this option: global_ocean.90x40x15.qshyd
916    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
917      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
918    o add on/off flag useOffLine for package OFFLINE
919    o seaice:
920      - modify advection so that it works also on the C-grid
921      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
922        problem in multi-tile runs with C-grid
923      - add flags for clipping ice velocities and/or masking solver forcing
924      - fix drag (ocean on ice) formulation and a bug that caused noise in the
925        C-grid solver
926      - added a few comments to seaice_diffusion.F
927      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
928        are now exclusive)
929      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
930        required re-ordering the code a little:
931       + make DAIRN global variable (defined in SEAICE)
932       + move computation of the viscosities eta and zeta into a new separate
933         routine (because I need to recompute them in seaice_ocean_stress.F)
934    
935    checkpoint58b_post
936    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
937      update output.txt of exp. aim.5l_cs.thSI
938    o various mnc cleanups and improvements:
939      + shrink lookup tables by factor of ~4
940      + better error reporting when running out of lookup space
941      + able to handle longer path/file names (up to 500 chars)
942    o adjoint:
943      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
944      - TBD: "hidden" mom_vecinv recomp. in dynamics
945    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
946     (allow to differentiate between forcing components using new integer flags:
947      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
948     and add new flag to put Dissipation tendency out of Adams-Bashforth.
949    o ecco
950      - enable trend removal from SSH anomaly obs.
951    o adjoint
952      - a fix for PmEpR when #undef EXACT_CONSERV
953      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
954      - try to fix "hidden" recomp. in forward_step for NLFS
955        (NLFS seems broken sometimes after I checked it in)
956    o seaice:
957     - add c-grid version of the dynamic solver:
958       + three new routines that are the c-grid substitute lsr, dynsolver
959         and ostres
960       + put a few fields that were local to dynsolver into global common
961         blocks, so that I can move the computation of stresses etc into
962         seaice_lsr (saves coding but may break the adjoint).
963     - replace more hardwired parameters by runtime parameters
964     - add ice masks that mask the rhs of the implicit solvers where there
965       is no ice (commented out in seaice_dynsolver, because i am not sure
966       if this works properly), eventually this should replace the clipping
967       of ice velocities in seaice_dynsolver to +/-40cm/s.
968    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
969      include it only where its needed
970    o move balancing of fluxes before the call of external_forcing_surf
971    o seaice:
972      - correct units of turning angles (now they are really in degrees)
973      - move computation of GWATX/Y out of main routine into dynsolver
974      - initialize GWATX/Y in seaice_init
975    o Apply mask on Fresh-Water flux (needed for SSH forcing).
976      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
977    o seaice: add runtime flags for turning angles (default to zero)
978    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
979      and trend from exf forcing and ctrl control adjustments
980    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
981      (since checkpoint57x_post)
982    o change the default rotation period to 86164.s = the Earth rotation
983    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
984      and based on a reference stratification. Tested within hs94.cs-32x32x5.
985    o seaice advection: add code for choosing between the default (2nd order
986      central differences) and multiDim advection schemes provided by
987      pkg/generic_advdiff
988    o seaice:
989      - removed all references to SEAICE_GRID.h fields from
990        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
991        (cubed-sphere configuration will change a little)
992      - grid computations in seaice_init are obsolete now.
993      - cleaned up code a little so that is easier to read (hopefully).
994      - added new (better?) discretizations of default advection and diffusion
995        (turn on with SEAICEuseFluxForm)
996      - replace 1 in 3d global fields by kSurface in growth.F
997      
998    checkpoint58a_post
999    o seaice:
1000      - bug fix in advect.F
1001    o shelfice:
1002      - separate shelfice load anomaly from pload (breaks with time
1003        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1004        Its default is 0., but it may be computed more cleverly from (unknown)
1005        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1006        done offline. A good approximation of the pressure load anomaly is
1007        necessary to avoid large initial adjustment processes underneath
1008        deep-reaching shelfice.
1009      - small fix in ISOMIP shelfice_thermodynamics
1010      - add more sophisticated thermodynamics of Hellmer (1989), this is
1011        now the default
1012      - give a few constants more intuitive names
1013    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1014      if bulk formulae are used in long integration (especially EmPmR). Turn
1015      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1016      if balancePrintMean, the imbalance that is substracted is printed to
1017      STDOUT.
1018    o fix bug (typo) in obcs_apply_eta.F
1019    o add a new package shelfice which enables us to model the circulation
1020      underneath shelf-ice with draughts of hundreds of meters.
1021     - works
1022     - to do: + include improved thermodynamics
1023              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1024                instead of new field kTopC
1025              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1026                instead of new field R_shelfIce and new code in ini_depth.F
1027                and ini_mask_etc.F?
1028              + adjust vertical mixing schemes?
1029    o seaice pkg:
1030     - add a cpp-flag to include a simple formula for a salinity dependent
1031       freezing point of sea water at the surface
1032     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1033       meridional stresses are now different (and hopefully correct)
1034    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1035       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1036       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1037    o pkg/diagnostics: add options and parameters for regional-statistics
1038       diagnostics ; define regions by reading a region-mask from a file
1039       (might add other options later)
1040    o pkg/bulk_force:
1041     - add option and parameters to use AIM surface-flux formulae.
1042     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1043       others forcing fields (defined in PARM05, parameter file "data") are loaded
1044       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1045     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1046     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1047     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1048       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1049     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1050    
1051    checkpoint58
1052    o add "--embed-source" option to genmake2 which, when the supporting
1053      tools can be compiled (as determined by genmake2) will turn on the
1054      embed_files package which then embeds the entire MITgcm source code
1055      (*.[fFhc] + Makefile) used for the build within the executable
1056      - requested by CNH but off by default
1057      - adds a paltry <9MB to the mitgcmuv executable in most cases
1058      - only writes the output when useEMBEDSRC in eedata is true
1059    o clean up 3-dim. relaxation codes:
1060      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1061      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1062      * Thanks to Tom Haine for testing!
1063    
1064    checkpoint57z_post
1065    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1066      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1067    o fix the pickup behavior for obcs in combination with ptracers
1068    o fix a bug in ptracers_external_fields_load
1069    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1070      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1071    o transfered surface NH pressure to eta field (if exactConserv).
1072    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1073         and update lab_sea output.txt file.
1074    o completing 3-dim. relaxation code: additional term
1075         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1076      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1077      * At compile time, in "EXF_OPTIONS.h" set
1078          #define  ALLOW_CLIMTEMP_RELAXATION
1079          #define  ALLOW_CLIMSALT_RELAXATION
1080      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1081          tauThetaClimRelax3Dim = 15552000.0,
1082          tauSaltClimRelax3Dim  = 15552000.0,
1083      * 3 cases:
1084          1) Use a constant-in-time 3-dim. field
1085          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1086          3) Real-time relax. to time-evolving prescribed field
1087    o Adding Laplacian-type smoothness constraint on
1088      initial and boundary (forcing) controls (ic, bc)
1089      * enable at compile-time via
1090        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1091      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1092      * Absolute scale somewhat unclear so far
1093      * no area weighting was included since no other cost term does so far
1094    
1095    checkpoint57y_post
1096    First step for a NLFS adjoint
1097    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1098    o new init. routines for calc_r_star, calc_surf_dr
1099    o still need to deal with ini_masks_etc
1100    o testreport seemed happy
1101    checkpoint57y_pre
1102    
1103    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1104    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1105    o add new offset feature to offline pkg (plus minor cleanup)
1106    o cfc fixes for final year of integration
1107    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1108      be in GCHEM_OPTIONS).
1109    
1110    checkpoint57x_post
1111    o fix testreport Pb in multiple test experiment.
1112    o cleanup our namelist syntax in verification:
1113      - make it more F95 standards compliant (some work still needed)
1114      - allows the vast majority of our tests to work with gfortran
1115    o Non-Hydrostatic:
1116     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1117     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1118    o Allow to apply AB on T,S rather than on AB(gT,gS):
1119     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1120     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1121       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1122     - need a "clever" read_pickup to restart from the other AB formulation
1123    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1124    o remove some unused variables (reduces number of compiler warnings)
1125    o adjoint
1126      * Disable useVariableViscosity for adjoint for time being
1127        (there are a number of extensive recomputations)
1128      * Initialize certain variables needed for adjoint
1129    
1130    checkpoint57w_post
1131    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1132                 fix the singleCpuIO RS version of MDSWRITEFIELD
1133       and add a WARNING if using globalFiles=T with multi-processors.
1134    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1135      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1136    o tracer advection scheme:
1137      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1138       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1139       was not very convenient).
1140      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1141       (further tests needed for the implicit DST & Flux-Limiter schemes).
1142    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1143      and sRef for convenience, handy, when you want to initialize
1144      ptracers in a large domain with a constant non-zero value. Also,
1145      untangle ptracers_init.F a little.
1146    
1147    checkpoint57v_post
1148    o change dome exp. to use variable viscosity in side-drag terms.
1149    o remove all the files from the cfc_offline test since they are now
1150      incorporated into tutorial_cfc_offline which has been producing
1151      identical results for a few days of testing
1152    o add new parameter: sideDragFactor to enable half-slip-side BC
1153      and change side-drag S/R to use viscosity from mom_calc_visc
1154      (can switch back by setting sideDragFactor=0.); affects results at
1155      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1156       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1157    o vorticity & strain are now computed without masking, to account for
1158      no-slip-side BC in variable viscosity calculation ; mask is applied
1159      anyway later on, before computing advection/coriolis terms.
1160    o modify exp4 to test new obcs support for reading from external files
1161      and for passive tracers
1162    o fix behavior of ptracers_monitor when monitor output is written to a
1163      netcdf-file; still not independent of monitor.F (writes in the same
1164      file).
1165    o change default value of tRef (put a uniform, meaningful value for ocean
1166      & atmos) and initialize sRef (was missing, as Martin mentioned).
1167    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1168      to be proportional to enstrophy dissipation length.  Thus,
1169       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1170      This is now consistent with Smagorinsky and with the manual.
1171    
1172    checkpoint57u_post
1173    o OBCS and PTRACERS: add open boundary support for passive tracers
1174      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1175        OB-values from file; this is not different from the way theta and salinity
1176        are treated
1177      - however, Orlanski-radiation conditions are not supported, and the model
1178        will stop if you use pTracers and Orlanski at the same time.
1179      - beefed up the rountine obcs_external_fields_load: now only those open
1180        boundary values are overwritten with values from files for which there
1181        are really files, otherwise the OB-fields remain untouched. This makes
1182        it possible to use different OBs at different ends of the domain (as
1183        with EXF)
1184    o reduce number of exch calls in shap_filt (s2).
1185    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1186      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1187    
1188    checkpoint57t_post
1189    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1190    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1191      same truncation, independent of the face number: affects affects several
1192      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1193    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1194      note that biharmonic viscosity + no-slip was not tested in any experiment.
1195    o fix bug in non-linear free-surf side-drag ; generate new output for
1196      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1197    o make mnc honor the writeBinaryPrec flag for most kinds of output
1198    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1199    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1200      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1201    o add brackets in multi-terms sum to get same truncation, independent of
1202      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1203      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1204    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1205      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1206      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1207      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1208      Suggested values of viscosity parameters found in mom_calc_visc.
1209      Many new viscosity diagnostics available.
1210    
1211    checkpoint57s_post
1212    o Add clearing-house for viscosity calculations, mom_calc_visc and
1213      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1214      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1215      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1216      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1217      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1218      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1219      ViscAhStrain and viscAhTension are now retired.
1220    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1221    o In response to JMC's bug report, genmake2 now ignores any soft-links
1222      that it finds in the *current* directory when searching for files.
1223      Soft-links found in any other source directories will still work as
1224      they did before.
1225    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1226      a C routine to unlimit the stack size
1227    o mnc-ify pkg/aim snapshot vars
1228    o mnc-ify pkg/land as requested by Daniel
1229    o various changes to mnc including:
1230      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1231      - output can now be grouped so that all files within a group
1232          change the ITER portion of their names in lock-step together
1233      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1234          and works with both EXCH1 and EXCH2 (but needs more testing)
1235      - writing works for all verification test cases w/ g77 on Linux
1236    
1237    checkpoint57r_post
1238    o make MNC variable initialization happen earlier
1239    o add diagnostics for (almost) each term of the momentum Eq.
1240    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1241    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1242    o remove MINIMAL_TAVE_OUTPUT option ;
1243      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1244    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1245      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1246    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1247    o add time-dependent SST, SSS control
1248    o cost terms in ecco/ modularized (new cost_generic.F)
1249    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1250    o new infrastructure for seaice model vs. obs misfits in seaice/
1251      * driver from the_main_loop.F is seaice_cost_driver.F
1252      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1253      * gradient check in Exp. 6a of natl_box_adjoint/
1254    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1255      (see README file)
1256    
1257    checkpoint57q_post
1258    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1259    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1260      - bug was reported by Jean-Michel and Ian Fenty
1261    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1262      update exp. cpl_aim+ocn output.
1263    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1264      Needed for high-res. runs with large global files
1265      to be able to limit tapelev size
1266    o Changed some tests for adjoint:
1267      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1268      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1269      * global_ocean.90x40x15/ back to default 3-level checkpointing
1270    o Modifications to enable scripted COMMON to MODULE conversion
1271      * verification/OpenAD/code/ has necessary scripts and description;
1272      * converts, compiles and runs successfully;
1273    
1274    checkpoint57p_post
1275    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1276    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1277      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1278    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1279    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1280      (was already the case for dissipation with mom_vecinv,
1281       and also the case for grad.PhiHyd when staggered-timeStep)
1282      This will allow to put dissipation out-off the AB time-stepping.
1283     Unfortunately, affects truncation error. Update output of exp. that "fails"
1284      (cg2d matching number) and leave the others for later: front_relax(10),
1285      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1286      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1287    
1288    checkpoint57o_post
1289    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1290      (2) its ready to be documented during the 20050801 DocFest
1291    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1292      for ideal_2D_oce and lab_sea on linux_ia32_g77
1293    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1294      in global1x1_tot/code_seaice_adj to access indices 32, 33
1295      (worth another tag)
1296    
1297    checkpoint57n_post
1298    o adding precip control xx_precip 32
1299    o adding swflux control xx_swflux 33
1300    o Replacing 10 forcing penalty cost routines by 1 generic.
1301    o Implementing partitioning in time-mean and variable adjustment
1302      for atmos. state.
1303    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1304    o in natl_box_adjoint:
1305      * updated exp 1 to 10
1306        (but does not have time-mean vs. variable split results yet)
1307    o updated global1x1/*_seaice_adj/
1308      to incorporate latest changes
1309    o enable useSingleCpuIO for mdsio vector routines
1310      (applies in particular to tapelev I/O)
1311    o removed inefficient K-loop in all active_file*control*.F
1312    
1313    checkpoint57m_post
1314    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1315      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1316    o pkg/exch2: filling of face-corner halo regions is optional
1317      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1318    
1319    checkpoint57l_post
1320     tag before updating tutorials (pre-release-2)
1321    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1322       for output and interpolation of input fields onto model grid)
1323    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1324       Affects results of exp. rotating_tank ; update output.txt.
1325    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
1326          and taking the square quantity and/or using a fraction-weight field.
1327    o fix aim_diagnostics_init.F mate numbers.
1328    o add mnc output capability to diagnostics/diagstat and update
1329      our cvsignore files for the ACSII output generated
1330    
1331    checkpoint57k_post
1332    o lab_sea now uses diagnostics package and provides a suite of
1333      new EXF diagnostics output.
1334    
1335    checkpoint57j_post
1336    o exf
1337      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1338        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1339        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1340      * extended diagnostics output
1341        - now includes all EXF variables
1342        - hs, hl moved to common block
1343        - separate S/R for diagnostics, called after ctrl vector is added
1344        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1345        - EXFqnet contains true Qnet (i.e. includes qsw)
1346      * updated verif. lab_sea, global_with_exf
1347      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1348        to ensure that diagnostics sees a true EXFqnet
1349    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1350    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1351      several times with different frequencies.
1352    o mnc-ify the thsice package as requested by Daniel Enderton
1353      - the monitor--MNC output needs work
1354      - many attributes need to be added (most are currently blank)
1355    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1356      - many attributes need to be added (most are currently blank)
1357    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
1358    o add Sadourny like discretization to the 4th.O vorticity advection scheme
1359    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
1360      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
1361         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
1362    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1363     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1364    
1365    checkpoint57i_post
1366    o Diagnostics package was changed: diagnostic allocation is now deactivated
1367      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1368    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1369      add 1rst Order upwind vertical Shear.
1370    o add a quick fix for A/B checkpointing in OFFLINE mode
1371    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1372      end-run around the C/Fortran linking horror in eesup/src/timers.F
1373    o added pkg/runclock: allows user to terminate run based on wall clock
1374    o added non-hydrostatic scaling parameter: nh_am2
1375    o pkg/my82: futile attempt to make results compiler-independent by adding
1376      some "_d 0", etc. no effect.
1377    o for mnc output, fill the 'T' coordinate var with myTime and create a
1378      separate 'iter' variable for iteration count
1379    o pkg/diagnostics:
1380      add new capability: output of Global/Regional & per-level statistics ;
1381      tested against monitor output (including land & thSIce) on various exp.
1382    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1383    
1384    checkpoint57h_done
1385      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1386      data.diagnostics, data.gchem, data.ptracers) is done.
1387    
1388    o pkg/diagnostics: prepare for Global/Regional statistics.
1389      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1390    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1391      and rename it: DIFFERENT_MULTIPLE
1392    
1393    checkpoint57h_post
1394    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1395    o pkg/diagnostics: change output frequency, now in seconds (instead
1396      of Nb of iterations). This requires to change data.diagnostics.
1397    checkpoint57h_pre
1398    
1399    o in mnc, let the user create the output dir if both mnc_outdir_date
1400      and mnc_outdir_num are false
1401    o add fflags() to pkg/diagnostics which allows one to specify, on a
1402      per-file basis, the file precision [default behavior is unchanged]
1403    o added diagnostics to pkg/kpp, including computation of mixed layer
1404      depth based on a temperature/density criterion
1405    o updated verification/natl_box to test the new pkg/kpp diagnostics
1406    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1407    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1408    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1409      not mnc -- this mistake was found by JMC and is now corrected
1410    
1411    checkpoint57g_post
1412    o add Adams-Bashforth 3rd Order time stepping:
1413      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1414      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1415    checkpoint57g_pre
1416    
1417    o make lambda[Theta,Salt]ClimRelax spatially varying
1418      (default remains spatially uniform constant based on tau)
1419    o added new control variables
1420      * init. uVel, vVel, etanN
1421      * lambda[Theta,Salt]ClimRelax
1422    o separate masks used for ctrl_pack/unpack 'from write_grid' output
1423      (suggested by G. Forget)
1424    
1425    checkpoint57f_post
1426    o add parameter "baseTime" = model base time = time at iteration zero
1427      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
1428      account for baseTime shift
1429    o move Coriolis arrays from PARAMS.h to GRID.h
1430    checkpoint57f_pre
1431    
1432    o mnc-ifying the seaice package
1433    o introduced an alternative length scale calculation for use in the limiting
1434      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
1435    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
1436    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1437      as well as grad(vort3).  Made it compatible with both approximate form
1438      for the cubed sphere and full form of these gradients.  Added flag
1439      useFullLeith to select between approximate and full form.  
1440    o add "d0" in getcon.F to reduce differences between compilers/platforms
1441      update output.txt of exp. fizhi-gridalt-hs
1442    o change port_rand funtion to allow to set the seed.
1443    o fix obscure MNC bug involving conversion between reals and integers
1444      - it caused no problems with certain (eg. gcc, ifc) compilers but the
1445        new version is now more standards-compliant
1446    o adjoint-related modifications
1447      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
1448      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
1449      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
1450    
1451    checkpoint57e_post
1452    o Adding eddy stress controls a la Ferreira et al.
1453    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
1454    
1455    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
1456      update output.txt of exp. fizhi-gridalt-hs
1457    o add more "Z" dimensions and associated coordinate vars to MNC
1458    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
1459    o parameter calendarDumps: when set, approximate months (30-31 days) and years
1460      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
1461      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
1462      months and years.  Requires pkg/cal.
1463    o diagnostics: add pickup functionality
1464      - off by default for backwards compatibility
1465      - current version only uses MDSIO -- MNC will be added
1466    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
1467    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
1468    
1469    checkpoint57d_post
1470    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
1471    o modify verification/ideal_2D_oce so that it tests the creation of mnc
1472      output from the diagnostics package
1473    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
1474    o make genmake2 more portable by using ".$FS" instead of ".f" for more
1475      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
1476    o add coordinate variables to the MNC output from the diagnostics package
1477    o change MNC-flags default value: true when useMNC=TRUE
1478    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
1479      the ability (off by default) to read the grid information using MNC
1480    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
1481    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
1482    o do snap-shot diagnostics at the middle of the time-interval (instead of
1483      at the end).
1484    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
1485      new test for AIM with thSIce + slab-ocean
1486    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
1487    o move state variable diagnostics to the beginning of the time step ;
1488      (note: still needs some work specially for snap-shot diagnostics)
1489      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
1490    
1491    checkpoint57c_post
1492    o Change testing option (-ieee) to get closer agreement between g77 & ifort
1493    o generate new output.txt files on faulks with g77 & the new -ieee option
1494    checkpoint57c_pre
1495    
1496    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
1497      update output.txt of exp. global_ocean.90x40x15
1498    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
1499      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
1500    o add saltFlux(+File) forcing capability with periodicExternalForcing
1501    o allow to use pkg diagnostics for GM-Redi & ThSIce output
1502    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
1503    o improvements for the MNC output from DIAGNOSTICS:
1504      - correct handling of the unlimitied dimension
1505      - all dims now have associated coordinate variables
1506      - variables located at U, V, and Corner ("Z") points are now written
1507        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
1508        *all* data points are output
1509    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
1510    o added pkg/seaice/seaice_monitor.F
1511    o mdsio_readfield.F can now read files visible only to master MPI process.
1512    o pkg/seaice: some test code for ice-modified ocean stress
1513    o exf_getffields interpolation defaults to bilinear for all scalar forcing
1514      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
1515      spurious negative numbers for precipitation and humidity.  Will cause
1516      some small numerical differences for integrations using pkg/exf/exf_interp.F.
1517    o pkg/ctrl/
1518      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
1519        May be enabled via doPackDiag
1520      *  introduce z-scaling of
1521         + gradient (doZscalePack) and
1522         + control (doZscaleUnpack)
1523    o pkg/mdsio/
1524      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
1525      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
1526    
1527    checkpoint57b_post
1528    o simplify options in diagnostics_fill arguments (remove weird combinations)
1529    o fix MNC coordinate variables so that they now contain per-face index
1530      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
1531      general, EXCH2 grids are only aligned to a "local" coordinate system
1532    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
1533    o Implement instantaneous output within pkg diagnostics:
1534      setting a negative frequency in data.diagnostics produces
1535     "snap-shot" output (as opposed to time-average if freq > 0)
1536    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
1537      NOTE: change ptracer diagnostics name: use 2 characters to work with
1538            more than 9 tracers. Add also diagnostics of advect & diffus flux.
1539    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
1540      becomes the coordinate variable for the 'T' dimension
1541    o add CF-style coordinate variables to MNC
1542      - just a first cut:  numbers are meaningless on the cubesphere and
1543        missing along the T axis but otherwise it works!
1544    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
1545    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
1546    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
1547      this is based directly on what the model compute, so that the content of
1548      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
1549    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
1550    o clean up build options files for SunOS, in particular
1551      - remove -traditional from xmakedepend
1552      - change -xarch=v9 to -xarch=native for f77
1553      - restore use of make (not gmake)
1554      - add CC=gcc if using g77
1555    o changes per discussion of AM, JMC, & EH3 today:
1556      - move redundant "grid" variables out of "state" -- in preparation of
1557        creating proper CF-style coordinate variables and in recognition
1558        that any/all grid variables can be easily copied (eg. w/NCO) from
1559        the grid files into any of the other NetCDF files
1560      - *always* output grid variables with MDSIO (this will eventually be
1561        changed)
1562      - output MNC grid file if useMNC is true
1563    o every instance of _END_MASTER() has been found and replaced with
1564      _END_MASTER( myThid ) in order to satisfy certain picky Sun
1565      preprocessors
1566    o re-arrange diagnostics pkg initialisation:
1567     - allow each package to extend the available diagnostics list
1568     - add some checking and fix small problems (multi-threaded, ...)
1569     - new S/R diagnostics_fill (replace fill_diagnostics):
1570       look through the short list of active diag. (instead of the long list)
1571       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
1572    
1573    checkpoint57a_post
1574    o this set of changes restores TAMC compatibility
1575      tested for global_ocean.90x40x15 adjoint on trough
1576      (what a pain)
1577    
1578    checkpoint57a_pre
1579    o some modifs in tools/build_options for sunos
1580    o call ctrl_pack for ctrl at end for optimcycle=0
1581    
1582    checkpoint57
1583    o add horizontal bi-harmonic viscosity for vertical velocity
1584      - new parameter viscA4W (defaults to viscA4)
1585      - affects only non-hydrostatic code
1586      - to be done: no-slip lateral boundary conditions
1587    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
1588    o implement Implicit Vertical advection for pTracers
1589    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
1590      (implemented also for implicit vertical diffusion & advection)
1591    o OBCS: extend application of tracer open boundary conditions
1592      to a strip beyond the boundary of width Olx/Oly
1593    o add call monitor to TAF set of required calls (flow directives)
1594      and include in natl_box_adjoint
1595    o untangle a few ifdefs related to cost, ctrl, autodiff
1596      untangel a few ALLOW_ECCO_OPTIMIZATION
1597    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
1598      (theta2, salt2 in ecco_cost_weights)
1599    
1600    checkpoint56c_post
1601    o OBCS as control variables
1602      - update ctrl_ad_diff.list, obcs_ad_diff.list
1603      - remove balance of obcs controls from default
1604      - fix index bug nobcs in ctrl_init
1605      - fix dummy fields filen in ctrl_pack
1606      - add dummy weights for obcs
1607    o lsopt: comment out fort.94 output
1608    o optim:
1609      - remove unnecessary header files
1610      - adjusted namelists
1611      - add xerbla.F to Makefile
1612    o exf:
1613      - multiple modifications of exf_check_range
1614      - unit change in exf_init_runoff from [m/year] to [m/s]
1615    o mdsio:
1616      - i/o-vector change debugLevel from debLevA to debLevB
1617    
1618    checkpoint56b_post
1619    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
1620      is called from DO_THE_MODEL_IO
1621      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
1622      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
1623      - clean up PTRACERS_WRITE_TIMEAVE a little
1624    o add another verification experiment that tests both the cfc-pkg and
1625      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
1626      reactive tendencies treated inline with regular timestepping
1627    o testreport previously did a lousy job of comparing small numbers, so
1628      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
1629      implemented in the little c-progam tmp_cmpnum.c which is embedded in
1630      testreport.
1631    o ptracers_monitor: bug fix for MPI
1632    
1633    checkpoint56a_post
1634    o GCHEM: finish reorganizating the package
1635      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
1636        (introduces another 3D-array for each passive tracer, but only if
1637        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
1638        gchemTendency is not needed because the timestep is done separately)
1639      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
1640      - GCHEM is now---more or less cleanly---separate from PTRACERS
1641      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
1642        so clear to me how that should be done in a general way.
1643    o CFC: improve formatting of output in CFC_ATMOS
1644    o PTRACERS:
1645      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
1646        that ALL experiments with ptracers enable can be checked. This makes
1647        GCHEM_MONITOR obsolete.
1648      - include a runtime parameter PTRACERS_monitorFreq that defaults to
1649        monitorFreq
1650      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
1651    o add PTRACERS (PTR0[1-5]) to testreport output
1652    o exf_check_range:
1653      * default changed to .TRUE.
1654      * will check values for niter0 if debLevA, every timestep if debLevB
1655      * STOP in exf_check_range if 'out of range'
1656      * range chosen generous to allow for potential extema
1657      TBD: a version with stricter range
1658           permitted range would be runtime parameters
1659    o GMredi:
1660      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
1661      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
1662      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
1663    o GCHEM:
1664      - move call to GCHEM_FORCING_SEP, so that it is now called before
1665        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
1666      - introduced a useGCHEM runtime flag and applied it everywhere.
1667      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1668        this flag is now only visible within GCHEM-pkg routines.
1669      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1670        be replaced by a 3D array that is computed before thermodynamics; for
1671        this, the tracer ID iTracer had to be included into the parameter list
1672        of ptracers_forcing
1673      - set up forward_step to call gchem_forcing, that will replace
1674        gchem_forcing_int in ptracers_forcing
1675      - cleaning up
1676    o small cleaning of exch2: remove files that are also in eesupp/src
1677    
1678    checkpoint56
1679    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
1680    o mnc: cleanup "full" files--fixes out-of-memory problem
1681    o ECCO-GODAE
1682      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
1683      * fully merged and updated from SIO code
1684        windstress sign change affects
1685        - exf_inscal_[u/v]stress
1686        - sign of xx_tau[u/v] adjustments
1687        - signs in cost_scat
1688      * ctrl_get_gen: avoid update of tau[u/v] for first few days
1689      * natl_box_adjoint updated and compressed
1690      * 2-level checkpoint switch added
1691        (tested in EXP. 1 of natl_box_adjoint)
1692      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
1693    o SVD
1694      * first complete, non-hacked version for SVD calculations
1695      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
1696        performed via direct access files admtlm_vector.it????
1697        (via ctrl_[un]pack)
1698      * optimcycle is used for ARPACK iteration counter
1699        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
1700      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
1701        and add linear transforms where necessary
1702      * controls are initial/final SST, SSS (can be extended; need to check
1703        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
1704    o mdsio: filename info to both stderr, stdout
1705    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
1706      from sign change
1707    
1708    checkpoint55j_post
1709    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
1710      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1711    o add consistent build directories and .cvsignore files to verification
1712    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
1713    o make all subroutines 30 or less characters in length for certain older
1714      compilers to work (a thorough search only turns up two routines in
1715      pkg/ptracers)
1716    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
1717      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
1718    
1719    checkpoint55i_post
1720    o change arrays for total vertical diffusivity (2.D if explicit,
1721      3.D if implicit) ; each ptracer uses its own background value.
1722    o added mnc/NetCDF output capability to ocn_compon_interf
1723      - added bits to verification/cpl_aim+ocn so that it can run on
1724        ITRDA and other clusters without the mpirun "-wd" option
1725    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
1726      configuration
1727    o give MNC the ability to create additional files rather than
1728      exceeding a specified file size limit "MNC_MAX_FILESIZE"
1729      - the default is just less than 2GB which is a practical limit
1730        on many systems
1731    o Compute the non-local term using either KPP vertical diffusivity (=default)
1732       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
1733    
1734    checkpoint55h_post
1735    o add verification test "vermix"
1736    o remove all the *_ioinc flags and replace with the single global
1737      outputTypesInclusive flag
1738    o allow to set a vertical profile of vertical diffusivity for T & S
1739    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
1740    o useMNC moved from data.mnc to data.pkg
1741    
1742    checkpoint55g_post
1743    o Renaming carbon AD experiments to comply with testreport conventions
1744    o Updating adjoint of Held-Suarez hs94.1x64x5
1745    o Fixing directives for non-ECCO forward_step, after ECCO directives
1746      have been fixed to avoid recomp. of do_oceanic_phys
1747      Works well for global_ocean.90x40x15,
1748      but recomp. issue remains for carbon
1749    o Updating adjoint output for natl_box_adjoint after
1750      pkg/ecco has been modified (see taga c55d_post)
1751    
1752    checkpoint55f_post
1753    o rename to timeave_init_fixed
1754    
1755    checkpoint55e_post
1756    o some delicate re-shuffle of store directives to avoid one
1757      extra call of do_oceanic_physics
1758      affects ecco_the_main_loop.F, do_oceanic_physics.F
1759      checkpoint_lev1_directives.h
1760    o NB: this may break global_ocean adjoint temporarily,
1761      but it is clear how to fix it. Will do later, need this now.
1762    
1763    checkpoint55d_post
1764    o ECCO specific cost function terms (up-to-date with 1x1 runs)
1765    o ecco_cost_weights is modified to 1x1 runs
1766    o modifs to allow observations to be read in as
1767      single file or yearly files
1768    o enable to read exf forcing fields as either
1769      single file or yearly files (flag useExfYearlyFields)
1770    checkpoint55d_pre
1771    
1772    o switch between 2-level and 3-level checkpointing
1773    o add ability of MNC to write local and "partial" (eg. 2D slices where
1774      the full 3D field is never actually stored) arrays to NetCDF files
1775      with the correct (that is, the complete multi-dimensional) set of
1776      array indicies
1777      - used in mom_vecinv() to write the diagFreq output
1778      - tested (demonstrated) in verification/aim.5l_cs
1779    o further mnc-ification
1780      - add verification/lab_sea to the list with mnc setups
1781      - fix undefined mnc v-names in cd_code
1782      - add kpp to mnc output (both snapshot and timeave)
1783    o non-hydrostatic code
1784      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
1785        in calc_gw.F
1786      - defaults to viscAh
1787      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
1788        friction or Leith) in non-hydrostatic mode, as long as there is
1789        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
1790    o pkg/cost
1791      extend simple cost functions to treat time mean quantities
1792      (T,U,V) via cost_accumulate_state from cost_tile
1793    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
1794        be 2 times larger than the minimum size the advection scheme requires.
1795        now get a perfect conservation of salt in advect_cs test-exp (updated)
1796    o GGL90 (Gaspar's TKE mixed layer)
1797      - add horizontal diffusion of TKE, requires exchanges in
1798        do_fields_blocking_exchanges, horizontal diffusivity is zero by
1799        default. In OPA there is no horizontal diffusion of TKE but the
1800        mixing coefficients are computed from a horizontal average of TKE of
1801        6 points or so. I think that diffusion has a little more physical
1802        justification.
1803      - clean up ggl90_calc in the hope of reducing memory usage (this hope
1804        was in vain)
1805      - mask tke-variable in ggl90_init
1806    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
1807    o fix biharmonic diffusion on CS-grid.
1808    o more obcs stuff
1809      - added obcs_external_fields_load as an alternative to the EXF-pkg option
1810        for reading boundary values. This routine is called from
1811        obcs_prescribe_read
1812      - updated obcs_check
1813      - changed sponge layer relaxation parameter units for days to seconds
1814      - turned off sponge layer by default
1815      - changed argument list of OBCS_CALC to myTime+deltaTclock
1816      - fixed about 35 bugs in obcs_external_fields_load
1817    
1818    checkpoint55c_post
1819    o obcs stuff
1820      - new runtime flags useOBCSprescribe, useOBCSbalance
1821      - re-arranged obcs_calc
1822      - moved exf_getobcs to obcs_prescibe_read
1823        obcs_prescibe_read is called after ORLANSKI stuff
1824        and independent of it (executable can contain all).
1825      - updated obcs_check
1826      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
1827        These may be necessary only if tangential velocities are
1828        prescribed at OB, not sure, needs testing.
1829    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
1830      which simplifies the calls and passes the ifc check-bounds test
1831    
1832    checkpoint55b_post
1833    o add a 2D scalar, Z location, exchange_2 routine.
1834    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
1835      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
1836      affects advect_cs results (for the wrong reason): update output.txt
1837    o use a more standard discretization for biharmonic viscosity ;
1838     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
1839      affects results of dome set-up: update output.txt
1840    o fix gad_advection.F (CubedSphere part), back to version 1.23
1841    o fix bug in mom_vi_del2uv.F (CubedSphere part).
1842    
1843    checkpoint55a_post
1844    o merged code to
1845      * prescribe/read time-dependent open boundaries
1846        (works in conjunction with exf, cal)
1847      * sponge layer code for open boundaries
1848      * each boundary N/S/E/W now has its own CPP option
1849        (healthy for the adjoint)
1850    
1851    checkpoint55
1852    o up-to-date adjoint of previous breaks
1853      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
1854      - global_ocean_ebm: adjoint still needs fix (TLM ok)
1855      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
1856      - carbon: * remove tr1-related adjoint verification
1857                * add ptracer as control variable
1858    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
1859      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
1860    
1861    checkpoint54f_post
1862    o in verification/carbin/ remove experiment related to
1863      ALLOW_PASSIVE_TRACER (array tr1 etc)
1864      code_ad/ input_ad/ results_ad
1865    
1866    o add two new packages
1867      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
1868        + subject to optimization (memory)
1869      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
1870        + subject to reordering (many GOTOs in the original code)
1871        + so far opps is called for every (i,j) point, and then operates in
1872          the vertical; one may want to reorder the scheme in order operate in
1873          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
1874          fields)
1875    o overhaul of IO so that we now have flags for MDSIO and/or MNC
1876      - all verification tests compile and run with linux_ia32_g77
1877      - defaults are compatible with current input files--nothing
1878        should change if you were not previously using MNC
1879      - MNC output has been added in numerous places (eg. timeave)
1880        but there are still a few writes not yet do-able with MNC
1881        (this is in progress)
1882      - flags now allow for either/or/both use of MDSIO and MNC and
1883        documentation will soon follow
1884      - numerous small formatting cleanups for ProTeX
1885    o add version info (via BUILD_INFO.h) to MNC and stdout
1886    
1887    checkpoint54e_post
1888    o add two new packages
1889      - pp81 (Packanowski and Philander, 1981), Richardson number and
1890        stratification dependent mixing
1891      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
1892      - these scheme operate in a similar manner as KPP (without ghat, of
1893        course), however there is only one diffusivity that is used for both
1894        temperature and salinity (and passive tracers)ç
1895    o add offline package
1896    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
1897      provided by Stephanie Dutkiewicz
1898    o genmake2: add ability to search for C compilers and cleanup test output
1899      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
1900    
1901    checkpoint54d_post
1902    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
1903    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
1904      leading to additional shift by 5 days each year of integration
1905       (i.e. leading to considerable offset over the years)
1906    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
1907    o start with no AB and no initial filtering (staggerTimeStep):
1908      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
1909    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
1910      (external loading & cpl import/export stay in forward_step.F)
1911    o update coupling interface to work with new staggerTimeStep
1912    o change MDSIO ptracers_pickup.
1913    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
1914    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
1915    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
1916    
1917    checkpoint54c_post
1918    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
1919      this affects (truncation error) output.txt of test-exp:
1920       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
1921    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
1922    o change Qnet to always be the net heat flux, (+upward).
1923      affects (truncation error) output of natl_box exp.: updated
1924    o define the max number of passive tracers in PTRACERS_SIZE.h
1925    o start to test mnc routinely in exp0
1926    o add sea-ice loading (sIceLoad) as a new forcing field.
1927    
1928    checkpoint54b_post
1929    o add testreport "-j JOBS" option for parallel builds (tested and pretty
1930       impressive on Altix and Opteron systems)
1931    o diagnostics can now write NetCDF files through the mnc package
1932    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
1933    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
1934    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
1935      affects (truncation error) output of lab_sea & natl_box exp.: updated
1936    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
1937    
1938    checkpoint54a_post
1939    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
1940    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
1941    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
1942    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
1943      + internal_wave (shift in writing cg2d_ini_res)
1944    checkpoint54a_pre
1945    
1946    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
1947      - modified verification/lab_sea and natl_box_adjoint accordingly
1948    
1949  checkpoint54  checkpoint54
1950  checkpoint53g_post  checkpoint53g_post
1951  o prepare splitting of thermodynamics: store convect.counter in common block  o prepare splitting of thermodynamics: store convect.counter in common block
