4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
8  o moved ptracer ctrl index 17 -> 32    (#ifdef ALLOW_SALT_PLUME)
9    o gather_2d/scatter_2d: removed halo regions
10    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
11      scheme and the corresponding test case (under front_relax dir). For now,
12      only available with Skew-flux form and not yet tested in realistic set-up.
13      adjoint: store directives updated, but gradient checks deteriorated,
14      so maybe GM/Redi adjoint is now broken.
15    o seaice adjoint
16      * add AREA, HEFF, HSNOW as control variable
17        (should not change lab_sea results)
18      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
19    o pkg/seaice:
20      * added computation of saltFlux in seaice_growth;
21        For time being, sea ice salinity is assumed constant
22        contribution of snow flooding to freshening of sea ice is neglected.
23        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
24        defaults to 0.0 in order to maintain backward compatibility.
25        Typical values for SEAICE_salinity are 4 to 10 g/kg.
26      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
27      * added SEAICE_availHeatFrac, which specifies fraction of surface level
28        heat content used to melt or grow ice
29      * commented out cap of HICE: it helps keep ice thinner
30      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
31      * applied OBCS T/S mask to HEFFM sea ice mask
32    
33    checkpoint59d
34    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
35     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
36     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
37    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
38     and change default value of parameter "GM_Small_Number";
39     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
40       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
41       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
42    o pkg/ecco: cost function when applying pkg/smooth to controls
43    o pkg/ctrl: add forcingPrecond run time parameter
44    o pkg/seaice:
45     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
46     - fix bug in metric terms of u-equation in LSR solver (implicit part),
47       changes verification/lab_sea
48     - rearrange implicit part of u-equation in LSR solver to make it easier to
49       read, understand, and debug. This causes changes at the truncation level.
50     - fix (serious) bug in the boundary conditions (sign error in the implicit
51       part) of the LSR solver. Changes all LSR results.
52     - fixed problem with HSNOW initialization to avoid thick snow when AREA
53       is initilized with small values - does not change lab_sea results.
54     - added HsnowFile initialization capability
55    o pkg/smooth: addition to model/src and pkg/ctrl so allow
56     initialization of pkg/smooth and application to control vector
57    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
58    o dependencies: pkg/profiles requires pkg/cal
59    o pkg/profiles:
60     - added option ALLOW_PROFILES_GENERICGRID
61         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
62         that interpolation information (grid points and coefficients) is provided
63         within the netcdf input files.
64         -> sample matlab scripts can be found in MITgcm_contrib/gael
65         that allow you to prepare netcdf input files.
66     - also modified: cleaner include statements, cleaner error print statements,
67       cleaner stops when error, and more tests of the netcdf input files consistency.
68    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
69    o pkg/seaice:
70     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
71       requires a new routine: seaice_diagnostics_fill.F
72     - make sure that seaice does not move if not forced (pressure replacement
73       method, Hibler and Ip, 1995), changes results
74     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
75     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
76       It is turned off by default (=-1.), because it changes the results.
77     - make it possible to read AREA from a file, too.
78    
79    checkpoint59c
80    o add S/R and diagnostics for oceanic mixed-layer depth
81    o move GMRedi call after all vertical mixing schemes (including KPP)
82    o pkg/thsice:
83     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
84      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
85    o pkg/obcs:
86     - bug fix for balance code
87    o pkg/seaice:
88      - allow values of SEAICE_elasticParm > 1
89      - add new parameter SEAICE_evpTauRelax as an alternative
90        to SEAICE_elasticParm
91      - make lsr boundary conditions free slip (by default), changes result
92      - add code for no slip boundary conditions for lsr
93      - set minimum of zeta to zero (and not 4e8) (changes results)
94      - add a cap on AREA after advecting AREA if seaice_growth is not called
95    o change calculation of Visbeck K:
96      - no longer depend on tapering scheme; instead, compute slope (limited
97        by GM_maxSlope). this is equivalent to what was comuted before with
98        clipping or linear tappering.
99      - fix vertical averaging (wrong by 1/2 level)
100      - leave the old version (but will not be maintained) within
101        #ifdef OLD_VISBECK_CALC / #endif
102      - update output of exp. ideal_2D_oce
103    o change error catch in calc_r_star to improve vectorization
104    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
105      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
106    o adjoint:
107      Re-organized adjoint checkpointing according to Matt Mazloff
108      (but with modifs/completions/cleanups)
109      Storing is now bundled into large arrays to optimized I/O
110      (and second step in cleanup of the_main_loop)
111    
112    checkpoint59b
113    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
114      - export/import (between ocean & coupler) fields needed for ocean DIC.
115    o pkg/seaice:
116      - get rid of three more exchanges seaice_calc_viscosities (required
117        different loop boundaries in seaice_lsr and seaice_ocean_stress)
118      - bug fix in seaice_ocean_stress (update of lab_sea required)
119      - reduce loop boundaries to necessary minimum also in seaice_evp
120      - go back to the old way of computing deltaC/Z as the adjoint likes that
121        better
122    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
123      passive tracer to an Age Tracer) + update output.txt
124    o pkg/exf:
125      - implement A-grid / C-grid selection for wind-stress input files.
126      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
127      for now, in exf_bulk_largeyeager04.F only :
128      - change implementation for case where windspeed + 2. components wind-stress
129        are read-in. AND use rhoConstFresh to convert evap.
130    o pkg/seaice:
131      - use correct EXCH_UV for wind-forcing (on A-grid).
132      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
133        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
134    o pkg/exf:
135      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
136      EXF_INTERPOLATION:
137      - merge global_with_exf/code version of exf_interp_read.F
138        to the main code ;
139      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
140        reading the file ; Important: This options needs to be defined to recover
141        previous code.
142        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
143      - no longer loose real*8 precision along the way when using exf_iprec=64.
144    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
145      - change discretisation of evp-solver in order to avoid another exchange
146        (changes lab_sea) and clean up a little
147      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
148        help the adjoint (this also changes the results slightly)
149      - add a few "_d 0" where they had been missing in seaice_evp.F
150      - cleaning up: remove unused seaice_calc_rhs.F
151    o pkg/exf: some cleaning-up:
152      - change various "constants" into runtime parameters
153      - cleaned-up Large&Yeager04 routine which should eventually
154        replace exf_bulkformulae.F (changed names of S/R and CPP)
155        and merged various ALLOW_ATM_WIND options
156     only used with thsice pkg (in thsice_get_exf.F):
157      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
158        which are used when useStabilityFct_overIce=TRUE (= the default)
159      - change default values of ice & snow emissivity and scale downward LW
160        by ice & snow emissivity.
161    o pkg/thsice:
162     fix few little problems, in thsice_calc_thickn.F:
163      - growth vertically (and not laterally) if iceFrac == iceMaskMax
164      - melt only laterally if hIce < hThinIce (as the comments say)
165      and in thsice_extend.F:
166      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
167      - start to form ice as soon as the minimum ice-volume is reachable.
168     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
169      and cpl_aim+ocn
170    o pkg/kpp
171     - move computation of surface related input fields to KPP into a new
172       subroutine kpp_forcing_surf.F
173     - remove wrong (within bi,bj loops) EXCH calls.
174     - little cleaning (add argument myThid in last position, cvs header ...)
175     - for now, fix conservation problem by exchanging KPPviscAz (may not
176       be the best fix)
177    o pkg/seaice
178     - check for inconsistent evp parameter/cpp-flag combination
179     - remove leftover errIO flat for obsolete name list error handling
180    o OpenAD
181     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
182    
183    checkpoint59a
184    o pkg/seaice: some parameter clarifications and a little bit of clean up
185    o pkg/thsice: rename run-time parameters:
186       himin       -> hIceMin
187       himin0      -> hThinIce
188       hihig       -> hThickIce
189       i0          -> i0swFrac
190       transCoef   -> bMeltCoef
191       frac_energy -> fracMelting
192      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
193       with default values (for now) that do not change the results.
194      remove old version of thsice vars advection in pkg/seaice.
195    o in FFIELDS.h:
196      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
197      - make pLoad & sIceLoad always available (but still only used if
198         ATMOSPHERIC_LOADING is #define).
199    o pkg/kpp: replaced _KPP_RL with _RL
200    o bug fixes for vertical diffusivity computations when both KPP and
201        3D diffusivity arrays are used.
202    o pkg/seaice: fix bug in evp solver, while doing that
203      - change (improve?) discretization of stress computations for both
204        cgrid-lsr and evp solver
205      - add a new routine to compute strain rates
206      - the above changes lab_sea results
207      - add no slip conditions for evp solver (off by default), lsr-version
208        may follow
209      - fix exchange for shear at Z-points (does not change lab_sea)
210      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
211        (to force the user to pick a time step since there is not "safe" way
212        of choosing it)
213      - add principal stress diagnostics
214      - rearrange fields for evp a little to avoid having to call a: too many
215        exchanges and b: exchanges for stress trensor components which we do
216        not have.
217      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
218        of evp, complete rewrite for lsr case (latter is does not yet work
219        in all cases)
220    o pkg/kpp: add code to have mixing in shelf ice caverns
221      - add myThid to all kpp routines (long overdue)
222    
223    checkpoint59
224    o pkg/exf:
225      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
226        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
227      - move exf header files from lower_case.h to UPPER_CASE.h ;
228        add missing cvs Header & Name
229      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
230      - add namelist param. selectStressGridPosition, exf_monFreq
231      - retire many _CLIM routines, and remove data.exf_clim
232        + params moved to data.exf
233        + climsst, climsss now handled by exf_set_gen, i.e.
234          climss?period=0 refers to constant field,
235          climss?period=-12 to monthly forcing
236      - split up namelists in data.exf
237    o pkg/seaice:
238      - remove seaice_exch and seaice_exch_uv
239      - remove superfluous exchange of theta
240      - add myThid to seaice_budget_ocean/ice
241      - add new interface for atmospheric wind forcing (C-grid only)
242        + new routine
243        + two new field (taux, tauy for stress over ice)
244        + removed one global field (DAIRN) for C-grid case only
245    o pkg/thsise
246      - 2nd set of modifs for thsice adjoint in conjunction with exf
247    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
248    
249    checkpoint58y_post
250    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
251      vertical diffusivity, similar to that in MOM4; turned on using
252      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
253      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
254    o Added capability for 3D specification of background vertical diffusion
255      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
256      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
257      "data" file that contains the 3D vertical diffusivity coefficients.
258    o ice dynamics (pkg/seaice) with thsice thermodynamics:
259      - add code within pkg thsice to advect & diffuse sea-ice fields
260      similar to (and will replace) what has been added in  seaice_advdiff.F,
261      but: - conserving Mass, Heat & Salt.
262           - better when using non-linear advection scheme (not yet fully tested)
263           - can also be used in atmospheric set-up (for now, only the diffusion).
264    
265    checkpoint58x_post
266    o IO option for global-file compact format:
267      - add options when generating topology (utils/exch2/matlab-topology-generator)
268      - add I/O capability (pkg/mdsio).
269      - adapt utils/matlab/rdmds.m to read this format.
270      for now long-line format not yet supported by pkg/mdsio (& exch2).
271    o shelfice: add a few diagnostics
272    
273    checkpoint58w_post
274    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
275      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
276      (and replace horiVertRatio in NH code).
277      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
278                         and tutorial_plume_on_slope (sensitive to truncation)
279    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
280      directly to drive seaice model (C-grid only)
281    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
282     - reintroduce computation of wind from stress,
283     - compute tau (in exf_bulkformulae.F) from windstress averaged to
284       mass points to avoid tau = 0
285     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
286    o rdmnc.m: make it work with "global" files created with gluemnc
287    o rdmnc.m : some improvements in dealing with singleton dimension
288      (tested on all testreport mnc output files).
289    o genmake2: disable pkg/profiles if netcdf test fails.
290    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
291    o move call to cal_readparms up to make calendar parameters/variable available
292      to all packages
293    
294    checkpoint58v_post
295    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
296      useDynP_inEos_Zc tested.
297    o pkg/exf: changes to properly interpolate/mask/scale initial fields
298    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
299      and portions thereof.  See read_cs.txt for description and examples.
300    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
301      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
302      following the great-circle arc between those 2 points.
303    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
304      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
305    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
306     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
307     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
308     - still needs work (not working with some options ; efficiency to improve)
309       and serious testing.
310     - use this scheme for temperature & salinity in 2 advection test exp.:
311       advect_xy & advect_xz, respectively.
312    
313    checkpoint58u_post
314    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
315    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
316    o testreport: add option "-skipdir" to skip some test.
317    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
318      momentum calculation.
319    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
320    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
321      remove checkpoint.F and the_correction_step.F (no longer used);
322      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
323    o add option (linFSConserveTr) to correct for tracer source/sink due to
324      Linear Free surface
325    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
326    o pkg/thsice: fix reading mnc-pickups
327    
328    checkpoint58t_post
329    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
330    o pkg/mdsio:
331     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
332       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
333       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
334     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
335     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
336       either MDS_READ_FIELD or MDS_WRITE_FIELD )
337     - new S/R (to replace MDSWRITEMETA), which allows to write more
338       informations (variable names, time ...) to meta files.
339     - modify rdmds.m to give back the meta file content.
340    o pkg/diagnostics: change vertical interpolation to be safer, and more
341       flexible (define p-levels to interpolate to in data.diagnostics);
342      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
343       diagnostic pointer.
344    o pkg/seaice: more cleaning up of seaice_growth, added many comments
345    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
346    o fix multi-category seaice:
347     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
348       SEAICE_MULTICATEGORY
349     - fix short wave heat flux
350    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
351       and allow to use EVP solver. Change forward lab_sea: test both EVP
352       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
353    o Initial check-in of lab_sea adjoint
354      (very similar to natl_box_adjoint/code_seaice)
355      * used C-grid and EVP solver
356      * used KPP, GM/Redi
357      * uses inAdExact=.TRUE.
358      * gradient checks fail for both ADM and TLM
359        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
360        f.d. gradients actually seem more problematic than ADM, TLM gradients;
361        issue is related to forward mismatch between g77 an ifort
362    o pkg/seaice: overhaul of thermodynamics
363     - growth.F and groatb.F are replaced by new routine seaice_growth.F
364     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
365     - move a few global fields out of SEAICE.h into seaice_growth.F and
366       make them 2D (FICE/QNETO/ ...)
367     - remove FO (it is the same as QNETO)
368     - introduce a few local fields to avoid modifying external fields such
369       as atemp, etc.
370    
371    checkpoint58s_post
372    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
373      changed exf_set_gen.F so that
374        genperiod=0 means input file is one time-constant field and
375        genperiod=-12 means input file contains 12 monthly means
376    o CG2D: use pre-computed solver main-diagonal (stored in common block);
377      this affects truncation error ; generate new output file for exp. which
378      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
379        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
380        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
381        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
382        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
383        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
384    o start implementation of deep-atmosphere and anelastic formulation
385    o verification: remove 2nd copy of input files and use script "prepare_run"
386      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
387    o mom_common/vecinv/fluxform: fix a few initialisation isssues
388    o profiles: fix for multithreaded case
389    
390    o diagnostics: rename few diags:
391      s/'PRESSURE'/'RCENTER '/g
392      s/'TICE    '/'oceFreez'/g
393      s/'TAUX    '/'oceTAUX '/g
394      s/'TAUY    '/'oceTAUY '/g
395      s/'SWFLUX  '/'oceQsw  '/g
396      s/DIFx/DFxE/g
397      s/DIFy/DFyE/g
398      and add few ocean-forcing diagnostics:
399      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
400    o modifications to pkg/seaice/growth.F and budget.F, which change results of
401      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
402      as actual snow thickness.  It now refers everywhere to effective snow
403      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
404    
405    checkpoint58r_post
406    o modifications to pkg/seaice/growth.F, which change results of
407      lab_sea experiment: fixes pertain to melting snow over open water, to
408      masking EVAP under sea ice, and to using the correct AREA variable for
409      computations of EVAP, PRECIP, HSNOW, and GHEFF
410    o add ability to read bathy, salt, and theta using MNC (off by def)
411    o add flooding algorithm and advection of HSNOW for pkg/seaice;
412      both are turned off by default and do no change any results
413    o seaice advection with pkg/thsice: a step toward the use of non-linear
414      advection scheme, but #ifdef or commented out for now (requires more EXCH).
415    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
416      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
417      in natl_box (affects results @ truncation level: update output.txt)
418    o multi-threading and IO:
419      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
420      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
421        (needed to work with SingleCpuIO): tested in all verif. exp.
422    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
423      affects the results (but none of the verification test uses this scheme).
424    o Adding some pkg/diagnostics capability to pkg/seaice
425      (will certainly be subject to changes)
426    o ctrl: adding new control variables:
427      lwflux, lwdown, evap, snowprecip, apressure, runoff
428    
429    checkpoint58q_post
430    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
431      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
432      high_res_cube configuration by 4% on Columbia.
433    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
434      add (in global_with_exf/code) a version of EXF_INTERP_READ without
435      dynamical allocation (seems to work in multi-threaded).
436    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
437      single CPU io) so that TAF does not have to see EESUPPORT.h
438    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
439    
440    checkpoint58p_post
441    o obcs: stop if obcs is used with useCDscheme = .true.
442    o shelfice:
443     - fix a sign error so that no slip at shelfice interface works
444     - remove stop for combination non-hydrostatic code and shelfice. That does
445       not mean, that the results are correct, but at least they are numerically
446       stable
447    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
448    o added adjoint exch routined for all exch*3d* routines
449      and updated flow directives
450    
451    checkpoint58o_post
452    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
453      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
454    o change controling S/R for writing pickup file (new S/R do_write_pickup)
455      and clean-up reading/writing of pickup files.
456    o fix local version of read/write pickup (NH part) in rotating_tank/code
457    o simplify EXCH interface:
458     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
459     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
460    o added the regrid package
461    o shelfice:
462     - add a simple boundary layer scheme to reduce noise
463     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
464    
465    checkpoint58n_post
466    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
467       local variable (not in common block).
468    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
469      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
470      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
471        to work with SingleCpuIO.
472    o add "_d 0" to real constant of pkg/cfc subroutines ;
473       update exp. cfc_exemple & tutorial_cfc_offline output files.
474    o multi-threading and IO:
475      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
476        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
477      - barrier before and after reading.
478      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
479      - avoid using MDS_WRITELOCAL for LAND pkg output.
480      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
481        common-block variables ; Allows multi-threading with master-thread IO.
482    o change default MAX_NO_THREADS from 32 to 4 ;
483      and stop cleanly when MAX_NO_THREADS is too small.
484    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
485    
486    checkpoint58m_post
487    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
488       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
489    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
490       keep global_ocean.90x40x15 (for AD testing) with former secondary test
491       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
492    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
493        add MITgcm_tutorials (= code + all the tutorials)
494    o ecco, option to compute cost for total ssh (mean+anom)
495    o consistent with addition of ptracer and ssh in pkg/profiles
496    o profiles: adding ptracer and ssh
497    o testreport: change multi-test output-file name
498      (from output.txt.{name} to output.{name}.txt)
499    o profiles: now ok for mutli-tiles case
500    o seaice: add 4 parameters for different advection schemes for area,
501      (effective) seaice thickness, enthalphy, and snow height. Their default
502      is the standard parameter SEAICEadvScheme
503    o calc_gw:
504     - add cosFacU in zonal viscous flux (harmonic.visc.).
505     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
506       of tutorial_plume_on_slope.
507    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
508    o calc_gw: true flux-form, account for horizontal grid spacing.
509      update rotating_tank results, but not plume_on_slope (affected at
510      truncation level, 11 digits).
511    
512    checkpoint58l_post
513    o calc_gw:
514     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
515     - remove side-drag for now (need to fix it); update plume_on_slope results.
516     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
517    o commit code to make SST/SSS weights spatially variable
518      (based on either variable in-situ or variable initial T/S weights)
519    o pkg/ecco:
520      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
521        now based on horizontally varying weights wthetaLev, wsaltLev
522      * cost_averagesflags now returns year indices in addition to day, month
523      * sflux balance is performed on annual basis
524        (sflxumm, sfluxmm2, bal_sfluxmm)
525      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
526        including separate counting and multipliers
527    o pkg/rbcs
528      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
529    
530    checkpoint58k_post
531    o testreport:
532     - always build in dir. "build" (if not there, mkdir build instead of building
533       & running in input)
534     - run in dir run (if it exists), in build otherwise.
535     - call prepare_run (if input/prepare_run exists)
536     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
537    o pkg/exf modifications to interpolation and rotation routines for more
538       reasonable treatment of North Pole singularity: for tracers North Pole
539       value is set to northernmost zonal-mean value, for zonal velocity it is
540       set to zero, and for meridional velocity it is set to northernmost value.
541    o pkg/exf/exf_check_range.F
542     - add tile index to diagnostics and move stop statement to the very
543       end of the routine.
544    o pkg/diagnostics: (diagnostics_main_init.F)
545      define title of isomorphic variables according to the current config.
546    o pkg/thsice with pkg/seaice dynamics:
547    - fix domain of computation (interior only, required for exf) and do exchanges
548    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
549    o towards a standard way of dealing with multi-threading in MONITOR
550      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
551    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
552       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
553    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
554    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
555    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
556       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
557    o tracer advection:
558     - clean-up and simplify calc_common_factors.F
559     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
560       advection subroutine (but still not used within DST advection S/R)
561    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
562    
563    checkpoint58j_post
564    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
565      from file (collects calls previously in FORWARD_STEP)
566    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
567    o adjoint store dir. adjusted accordingly
568    o genmake2
569      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
570    
571    checkpoint58i_post
572    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
573      on wind stress (SEAICEstressFactor defaults to 1.)
574    o Total number of Timers is finite (<=40): comment out 2 non-essential one
575      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
576    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
577      on CS-grid: no longer loosing mass.
578    o exf & curvilinear-grid: no longer modify longitude xC & xG.
579    o pkg/ggl90: fix sloppy output and fix a bug
580    o pkg/seaice: added SEAICEuseEVPpickup parameter
581      - Set to false in order to start EVP solver with
582        non-EVP pickup files when using SEAICEuseEVP
583      - fix sign error in diffusion in seaice_calc_rhs
584    
585    checkpoint58h_post
586    * Modifications for bottom topography control
587      o replace hFacC by _hFacC at various places
588      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
589      o add non-self-adjoint cg2d_nsa
590      o update autodiff support routines
591      o re-initialise hfac after ctrl_depth_ini
592      o works for 5x5 box, doesnt work for global_ocean.90x40x15
593    * Adding verification for 5x5 box (4-layer) bottom topography control
594    
595    checkpoint58g_post
596    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
597       used for mean seasonal cycle, mean diurnal cycle); add an example
598       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
599    o pkg/ggl90:
600      - add parameter (minimum surface kinetic energy)
601      - fix bug (avoiding division by zero)
602    o couple pkg/thsice to pkg/seaice:
603      - modify advection in seaice to accomodate new scalar fields to be advected
604      - only muliDimAdection scheme work with seaice/thsice
605      - mapping of thsice-variables to seaice-variables, back and forth
606      - does not break the verification experiments, but does not give the
607        desired results either
608    o pkg/seaice
609      - make (default) second order advection a bit less confusing?
610    
611    checkpoint58f_post
612    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
613      to pkg/seaice):
614      - new routines thsice_map_exf and thsice_get_exf provide the interface
615      - add an additional formal parameter to thsice_solve4temp
616    o pkg/exf:
617      - add new fields wspeed, snowprecip (to be able to couple to thsice)
618      - correct Stefan-Boltzmann constant
619      - new parameter for longwave surface emittance
620      - separate some stuff from exf_bulkformulae into new routines  
621        exf_radiation, exf_wind
622      - add new parameters and constants: longwave emissivity for ocean, ice
623        and snow, evaporation parameters over ice
624      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
625        either wind from stress or stress from wind
626    o pkg/thSIce:
627    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
628    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
629       and THSICE_CALC_THICKN
630    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
631    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
632      to make debugging easier.
633    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
634    o pkg/bulk_force:
635      - clean-up comments and parameters ;
636      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
637    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
638      generate new output for test-experiment: aim.5l_cs.thSI
639    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
640      testreport accordingly
641    
642    checkpoint58e_post
643    o SEAICE_CGRID adjoint done
644    o R_STAR adjoint implemented.
645      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
646      * need to sort out init. of h0facc, etc.
647    o Make pkg/profile fully independent of ecco,cost, etc. stuff
648      to be able to use it in pure forward.
649    
650    checkpoint58d_post
651    o upgrade simple test-experiment to tutorial example:
652     step.1: duplicate the experiment and (step.2) will remove the old copy.
653      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
654      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
655      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
656      tutorial_global_oce_biogeo    <- copy of dic_example
657      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
658      tutorial_plume_on_slope       <- copy of plume_on_slope
659      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
660      tutorial_global_oce_optim     <- empty for now (David ?)
661      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
662     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
663    o correct a sign problem in cost_scat.F
664    o obcs and ptracers: fix boundary conditions for advections schemes
665      with larger stencil
666    o thsice adjoint: start
667    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
668      completeness
669    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
670      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
671    o ptracers adjoint:
672      * avoid extensive recomputatations
673      * fix missing re-init. of gptr (missed by TAF)
674    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
675      me to turn off the excessive output to STDOUT that this package produces
676    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
677      and add those terms in Vector-Invariant formulation.
678    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
679      if the control period (xx_hfluxperiod etc) is 0
680    o in profiles pkg, clean routines and fix details

682      fix problem in case the model does not start at iter0=0
683    o fix mnc-pickup/restart for ptracers
684    o new package prifiles:
685      code to compute profile-based cost by Gael Forget
686      (modifs in ecco, ctrl, autodiff)
687    o Benign bug fix in initialization (spotted by M. Mazloff) of
688      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
689    
690    checkpoint58c_post
691    o adjoint: finish NLFS adjoint and provide reference output in
692      verification/global_ocean.90x40x15/results_ad_nlfs
693    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
694      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
695      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
696      with SEAICE_CGRID defined.
697    o move calendarDumps from "data" to "data.cal" and clean-up the code
698      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
699    o add useEXF & useCAL flags (for now, set in hard-coded way)
700    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
701      (were missing in NH mode, and wrong in quasihydrostatic mode).
702      waiting for Chris updated version of calc_gw to add those CALLs.
703    o fix bug in quasihydrostatic S/R ;
704      add a test for this option: global_ocean.90x40x15.qshyd
705    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
706      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
707    o add on/off flag useOffLine for package OFFLINE
708    o seaice:
709      - modify advection so that it works also on the C-grid
710      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
711        problem in multi-tile runs with C-grid
712      - add flags for clipping ice velocities and/or masking solver forcing
713      - fix drag (ocean on ice) formulation and a bug that caused noise in the
714        C-grid solver
715      - added a few comments to seaice_diffusion.F
716      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
717        are now exclusive)
718      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
719        required re-ordering the code a little:
720       + make DAIRN global variable (defined in SEAICE)
721       + move computation of the viscosities eta and zeta into a new separate
722         routine (because I need to recompute them in seaice_ocean_stress.F)
723    
724    checkpoint58b_post
725    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
726      update output.txt of exp. aim.5l_cs.thSI
727    o various mnc cleanups and improvements:
728      + shrink lookup tables by factor of ~4
729      + better error reporting when running out of lookup space
730      + able to handle longer path/file names (up to 500 chars)
731    o adjoint:
732      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
733      - TBD: "hidden" mom_vecinv recomp. in dynamics
734    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
735     (allow to differentiate between forcing components using new integer flags:
736      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
737     and add new flag to put Dissipation tendency out of Adams-Bashforth.
738    o ecco
739      - enable trend removal from SSH anomaly obs.
740    o adjoint
741      - a fix for PmEpR when #undef EXACT_CONSERV
742      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
743      - try to fix "hidden" recomp. in forward_step for NLFS
744        (NLFS seems broken sometimes after I checked it in)
745    o seaice:
746     - add c-grid version of the dynamic solver:
747       + three new routines that are the c-grid substitute lsr, dynsolver
748         and ostres
749       + put a few fields that were local to dynsolver into global common
750         blocks, so that I can move the computation of stresses etc into
751         seaice_lsr (saves coding but may break the adjoint).
752     - replace more hardwired parameters by runtime parameters
753     - add ice masks that mask the rhs of the implicit solvers where there
754       is no ice (commented out in seaice_dynsolver, because i am not sure
755       if this works properly), eventually this should replace the clipping
756       of ice velocities in seaice_dynsolver to +/-40cm/s.
757    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
758      include it only where its needed
759    o move balancing of fluxes before the call of external_forcing_surf
760    o seaice:
761      - correct units of turning angles (now they are really in degrees)
762      - move computation of GWATX/Y out of main routine into dynsolver
763      - initialize GWATX/Y in seaice_init
764    o Apply mask on Fresh-Water flux (needed for SSH forcing).
765      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
766    o seaice: add runtime flags for turning angles (default to zero)
767    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
768      and trend from exf forcing and ctrl control adjustments
769    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
770      (since checkpoint57x_post)
771    o change the default rotation period to 86164.s = the Earth rotation
772    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
773      and based on a reference stratification. Tested within hs94.cs-32x32x5.
774    o seaice advection: add code for choosing between the default (2nd order
775      central differences) and multiDim advection schemes provided by
776      pkg/generic_advdiff
777    o seaice:
778      - removed all references to SEAICE_GRID.h fields from
779        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
780        (cubed-sphere configuration will change a little)
781      - grid computations in seaice_init are obsolete now.
782      - cleaned up code a little so that is easier to read (hopefully).
783      - added new (better?) discretizations of default advection and diffusion
784        (turn on with SEAICEuseFluxForm)
785      - replace 1 in 3d global fields by kSurface in growth.F
786      
787    checkpoint58a_post
788    o seaice:
789      - bug fix in advect.F
790    o shelfice:
791      - separate shelfice load anomaly from pload (breaks with time
792        dependent forcing), => introduce constant field shelficeLoadAnomaly.
793        Its default is 0., but it may be computed more cleverly from (unknown)
794        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
795        done offline. A good approximation of the pressure load anomaly is
796        necessary to avoid large initial adjustment processes underneath
797        deep-reaching shelfice.
798      - small fix in ISOMIP shelfice_thermodynamics
799      - add more sophisticated thermodynamics of Hellmer (1989), this is
800        now the default
801      - give a few constants more intuitive names
802    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
803      if bulk formulae are used in long integration (especially EmPmR). Turn
804      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
805      if balancePrintMean, the imbalance that is substracted is printed to
806      STDOUT.
807    o fix bug (typo) in obcs_apply_eta.F
808    o add a new package shelfice which enables us to model the circulation
809      underneath shelf-ice with draughts of hundreds of meters.
810     - works
811     - to do: + include improved thermodynamics
812              + check whether kSurfC (from model/inc/SURFACE.h) can be used
813                instead of new field kTopC
814              + can we use topoFile, Ro_surf and existing code in ini_depth.F
815                instead of new field R_shelfIce and new code in ini_depth.F
816                and ini_mask_etc.F?
817              + adjust vertical mixing schemes?
818    o seaice pkg:
819     - add a cpp-flag to include a simple formula for a salinity dependent
820       freezing point of sea water at the surface
821     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
822       meridional stresses are now different (and hopefully correct)
823    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
824       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
825       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
826    o pkg/diagnostics: add options and parameters for regional-statistics
827       diagnostics ; define regions by reading a region-mask from a file
828       (might add other options later)
829    o pkg/bulk_force:
830     - add option and parameters to use AIM surface-flux formulae.
831     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
832       others forcing fields (defined in PARM05, parameter file "data") are loaded
833       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
834     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
835     - use the right EXCH call for uwind,vwind (to work on CS-grid).
836     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
837       and parameters (note: calcWindStress replaces .NOT.readwindstress).
838     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
839    
840    checkpoint58
841    o add "--embed-source" option to genmake2 which, when the supporting
842      tools can be compiled (as determined by genmake2) will turn on the
843      embed_files package which then embeds the entire MITgcm source code
844      (*.[fFhc] + Makefile) used for the build within the executable
845      - requested by CNH but off by default
846      - adds a paltry <9MB to the mitgcmuv executable in most cases
847      - only writes the output when useEMBEDSRC in eedata is true
848    o clean up 3-dim. relaxation codes:
849      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
850      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
851      * Thanks to Tom Haine for testing!
852    
853    checkpoint57z_post
854    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
855      affects output (@ truncation level) of exp. plume_on_slope ; updated.
856    o fix the pickup behavior for obcs in combination with ptracers
857    o fix a bug in ptracers_external_fields_load
858    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
859      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
860    o transfered surface NH pressure to eta field (if exactConserv).
861    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
862         and update lab_sea output.txt file.
863    o completing 3-dim. relaxation code: additional term
864         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
865      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
866      * At compile time, in "EXF_OPTIONS.h" set
867          #define  ALLOW_CLIMTEMP_RELAXATION
868          #define  ALLOW_CLIMSALT_RELAXATION
869      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
870          tauThetaClimRelax3Dim = 15552000.0,
871          tauSaltClimRelax3Dim  = 15552000.0,
872      * 3 cases:
873          1) Use a constant-in-time 3-dim. field
874          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
875          3) Real-time relax. to time-evolving prescribed field
876    o Adding Laplacian-type smoothness constraint on
877      initial and boundary (forcing) controls (ic, bc)
878      * enable at compile-time via
879        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
880      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
881      * Absolute scale somewhat unclear so far
882      * no area weighting was included since no other cost term does so far
883    
884    checkpoint57y_post
885    First step for a NLFS adjoint
886    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
887    o new init. routines for calc_r_star, calc_surf_dr
888    o still need to deal with ini_masks_etc
889    o testreport seemed happy
890    checkpoint57y_pre
891    
892    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
893    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
894    o add new offset feature to offline pkg (plus minor cleanup)
895    o cfc fixes for final year of integration
896    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
897      be in GCHEM_OPTIONS).
898    
899    checkpoint57x_post
900    o fix testreport Pb in multiple test experiment.
901    o cleanup our namelist syntax in verification:
902      - make it more F95 standards compliant (some work still needed)
903      - allows the vast majority of our tests to work with gfortran
904    o Non-Hydrostatic:
905     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
906     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
907    o Allow to apply AB on T,S rather than on AB(gT,gS):
908     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
909     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
910       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
911     - need a "clever" read_pickup to restart from the other AB formulation
912    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
913    o remove some unused variables (reduces number of compiler warnings)
914    o adjoint
915      * Disable useVariableViscosity for adjoint for time being
916        (there are a number of extensive recomputations)
917      * Initialize certain variables needed for adjoint
918    
919    checkpoint57w_post
920    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
921                 fix the singleCpuIO RS version of MDSWRITEFIELD
922       and add a WARNING if using globalFiles=T with multi-processors.
923    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
924      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
925    o tracer advection scheme:
926      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
927       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
928       was not very convenient).
929      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
930       (further tests needed for the implicit DST & Flux-Limiter schemes).
931    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
932      and sRef for convenience, handy, when you want to initialize
933      ptracers in a large domain with a constant non-zero value. Also,
934      untangle ptracers_init.F a little.
935    
936    checkpoint57v_post
937    o change dome exp. to use variable viscosity in side-drag terms.
938    o remove all the files from the cfc_offline test since they are now
939      incorporated into tutorial_cfc_offline which has been producing
940      identical results for a few days of testing
941    o add new parameter: sideDragFactor to enable half-slip-side BC
942      and change side-drag S/R to use viscosity from mom_calc_visc
943      (can switch back by setting sideDragFactor=0.); affects results at
944      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
945       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
946    o vorticity & strain are now computed without masking, to account for
947      no-slip-side BC in variable viscosity calculation ; mask is applied
948      anyway later on, before computing advection/coriolis terms.
949    o modify exp4 to test new obcs support for reading from external files
950      and for passive tracers
951    o fix behavior of ptracers_monitor when monitor output is written to a
952      netcdf-file; still not independent of monitor.F (writes in the same
953      file).
954    o change default value of tRef (put a uniform, meaningful value for ocean
955      & atmos) and initialize sRef (was missing, as Martin mentioned).
956    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
957      to be proportional to enstrophy dissipation length.  Thus,
958       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
959      This is now consistent with Smagorinsky and with the manual.
960    
961    checkpoint57u_post
962    o OBCS and PTRACERS: add open boundary support for passive tracers
963      - either use homogenous (pseudo) v.Neumann conditions or prescribe
964        OB-values from file; this is not different from the way theta and salinity
965        are treated
966      - however, Orlanski-radiation conditions are not supported, and the model
967        will stop if you use pTracers and Orlanski at the same time.
968      - beefed up the rountine obcs_external_fields_load: now only those open
969        boundary values are overwritten with values from files for which there
970        are really files, otherwise the OB-fields remain untouched. This makes
971        it possible to use different OBs at different ends of the domain (as
972        with EXF)
973    o reduce number of exch calls in shap_filt (s2).
974    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
975      truncation level) 4/5 MLAdjust test results (11&12 digits match).
976    
977    checkpoint57t_post
978    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
979    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
980      same truncation, independent of the face number: affects affects several
981      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
982    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
983      note that biharmonic viscosity + no-slip was not tested in any experiment.
984    o fix bug in non-linear free-surf side-drag ; generate new output for
985      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
986    o make mnc honor the writeBinaryPrec flag for most kinds of output
987    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
988    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
989      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
990    o add brackets in multi-terms sum to get same truncation, independent of
991      the face number (manage to get exactly same value of gU,gV at the cs-edge)
992      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
993    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
994      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
995      a maximum grid-scale Reynolds number.  Also, changes all length calculations
996      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
997      Suggested values of viscosity parameters found in mom_calc_visc.
998      Many new viscosity diagnostics available.
999    
1000    checkpoint57s_post
1001    o Add clearing-house for viscosity calculations, mom_calc_visc and
1002      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1003      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1004      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1005      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1006      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1007      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1008      ViscAhStrain and viscAhTension are now retired.
1009    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1010    o In response to JMC's bug report, genmake2 now ignores any soft-links
1011      that it finds in the *current* directory when searching for files.
1012      Soft-links found in any other source directories will still work as
1013      they did before.
1014    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1015      a C routine to unlimit the stack size
1016    o mnc-ify pkg/aim snapshot vars
1017    o mnc-ify pkg/land as requested by Daniel
1018    o various changes to mnc including:
1019      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1020      - output can now be grouped so that all files within a group
1021          change the ITER portion of their names in lock-step together
1022      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1023          and works with both EXCH1 and EXCH2 (but needs more testing)
1024      - writing works for all verification test cases w/ g77 on Linux
1025    
1026    checkpoint57r_post
1027    o make MNC variable initialization happen earlier
1028    o add diagnostics for (almost) each term of the momentum Eq.
1029    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1030    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1031    o remove MINIMAL_TAVE_OUTPUT option ;
1032      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1033    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1034      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1035    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1036    o add time-dependent SST, SSS control
1037    o cost terms in ecco/ modularized (new cost_generic.F)
1038    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1039    o new infrastructure for seaice model vs. obs misfits in seaice/
1040      * driver from the_main_loop.F is seaice_cost_driver.F
1041      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1042      * gradient check in Exp. 6a of natl_box_adjoint/
1043    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1044      (see README file)
1045    
1046    checkpoint57q_post
1047    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1048    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1049      - bug was reported by Jean-Michel and Ian Fenty
1050    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1051      update exp. cpl_aim+ocn output.
1052    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1053      Needed for high-res. runs with large global files
1054      to be able to limit tapelev size
1055    o Changed some tests for adjoint:
1056      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1057      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1058      * global_ocean.90x40x15/ back to default 3-level checkpointing
1059    o Modifications to enable scripted COMMON to MODULE conversion
1060      * verification/OpenAD/code/ has necessary scripts and description;
1061      * converts, compiles and runs successfully;
1062    
1063    checkpoint57p_post
1064    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1065    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1066      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1067    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1068    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1069      (was already the case for dissipation with mom_vecinv,
1070       and also the case for grad.PhiHyd when staggered-timeStep)
1071      This will allow to put dissipation out-off the AB time-stepping.
1072     Unfortunately, affects truncation error. Update output of exp. that "fails"
1073      (cg2d matching number) and leave the others for later: front_relax(10),
1074      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1075      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1076    
1077    checkpoint57o_post
1078    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1079      (2) its ready to be documented during the 20050801 DocFest
1080    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1081      for ideal_2D_oce and lab_sea on linux_ia32_g77
1082    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1083      in global1x1_tot/code_seaice_adj to access indices 32, 33
1084      (worth another tag)
1085    
1086    checkpoint57n_post
1087    o adding precip control xx_precip 32
1088    o adding swflux control xx_swflux 33
1089    o Replacing 10 forcing penalty cost routines by 1 generic.
1090    o Implementing partitioning in time-mean and variable adjustment
1091      for atmos. state.
1092    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1093  o in natl_box_adjoint:  o in natl_box_adjoint:
1094    * updated: results_bulk/    * updated exp 1 to 10
1095    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
1096    o updated global1x1/*_seaice_adj/
1097      to incorporate latest changes
1098    o enable useSingleCpuIO for mdsio vector routines
1099      (applies in particular to tapelev I/O)
1100    o removed inefficient K-loop in all active_file*control*.F
1101    
1102  checkpoint57m_post  checkpoint57m_post
1103  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
