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

1593    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
1594      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
1595        this flag is now only visible within GCHEM-pkg routines.
1596      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
1597        be replaced by a 3D array that is computed before thermodynamics; for
1598        this, the tracer ID iTracer had to be included into the parameter list
1599        of ptracers_forcing
1600      - set up forward_step to call gchem_forcing, that will replace
1601        gchem_forcing_int in ptracers_forcing
1602      - cleaning up
1603  o small cleaning of exch2: remove files that are also in eesupp/src  o small cleaning of exch2: remove files that are also in eesupp/src
