4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o pkg/obcs:
8  o moved ptracer ctrl index 17 -> 32   - bug fix for balance code
9    o pkg/seaice:
10      - allow values of SEAICE_elasticParm > 1
11      - add new parameter SEAICE_evpTauRelax as an alternative
12        to SEAICE_elasticParm
13      - make lsr boundary conditions free slip (by default), changes result
14      - add code for no slip boundary conditions for lsr
15      - set minimum of zeta to zero (and not 4e8) (changes results)
16      - add a cap on AREA after advecting AREA if seaice_growth is not called
17    o change calculation of Visbeck K:
18      - no longer depend on tapering scheme; instead, compute slope (limited
19        by GM_maxSlope). this is equivalent to what was comuted before with
20        clipping or linear tappering.
21      - fix vertical averaging (wrong by 1 level)
22      - leave the old version (but will not be maintained) within
23        #ifdef OLD_VISBECK_CALC / #endif
24    o change error catch in calc_r_star to improve vectorization
25    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
26      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
27    
28    checkpoint59b
29    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
30      - export/import (between ocean & coupler) fields needed for ocean DIC.
31    o pkg/seaice:
32      - get rid of three more exchanges seaice_calc_viscosities (required
33        different loop boundaries in seaice_lsr and seaice_ocean_stress)
34      - bug fix in seaice_ocean_stress (update of lab_sea required)
35      - reduce loop boundaries to necessary minimum also in seaice_evp
36      - go back to the old way of computing deltaC/Z as the adjoint likes that
37        better
38    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
39      passive tracer to an Age Tracer) + update output.txt
40    o pkg/exf:
41      - implement A-grid / C-grid selection for wind-stress input files.
42      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
43      for now, in exf_bulk_largeyeager04.F only :
44      - change implementation for case where windspeed + 2. components wind-stress
45        are read-in. AND use rhoConstFresh to convert evap.
46    o pkg/seaice:
47      - use correct EXCH_UV for wind-forcing (on A-grid).
48      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
49        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
50    o pkg/exf:
51      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
52      EXF_INTERPOLATION:
53      - merge global_with_exf/code version of exf_interp_read.F
54        to the main code ;
55      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
56        reading the file ; Important: This options needs to be defined to recover
57        previous code.
58        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
59      - no longer loose real*8 precision along the way when using exf_iprec=64.
60    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
61      - change discretisation of evp-solver in order to avoid another exchange
62        (changes lab_sea) and clean up a little
63      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
64        help the adjoint (this also changes the results slightly)
65      - add a few "_d 0" where they had been missing in seaice_evp.F
66      - cleaning up: remove unused seaice_calc_rhs.F
67    o pkg/exf: some cleaning-up:
68      - change various "constants" into runtime parameters
69      - cleaned-up Large&Yeager04 routine which should eventually
70        replace exf_bulkformulae.F (changed names of S/R and CPP)
71        and merged various ALLOW_ATM_WIND options
72     only used with thsice pkg (in thsice_get_exf.F):
73      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
74        which are used when useStabilityFct_overIce=TRUE (= the default)
75      - change default values of ice & snow emissivity and scale downward LW
76        by ice & snow emissivity.
77    o pkg/thsice:
78     fix few little problems, in thsice_calc_thickn.F:
79      - growth vertically (and not laterally) if iceFrac == iceMaskMax
80      - melt laterally only if hIce < hThinIce (as the comments say)
81      and in thsice_extend.F:
82      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
83      - start to form ice as soon as the minimum ice-volume is reachable.
84     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
85      and cpl_aim+ocn
86    o pkg/kpp
87     - move computation of surface related input fields to KPP into a new
88       subroutine kpp_forcing_surf.F
89     - remove wrong (within bi,bj loops) EXCH calls.
90     - little cleaning (add argument myThid in last position, cvs header ...)
91     - for now, fix conservation problem by exchanging KPPviscAz (may not
92       be the best fix)
93    o pkg/seaice
94     - check for inconsistent evp parameter/cpp-flag combination
95     - remove leftover errIO flat for obsolete name list error handling
96    o OpenAD
97     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
98    
99    checkpoint59a
100    o pkg/seaice: some parameter clarifications and a little bit of clean up
101    o pkg/thsice: rename run-time parameters:
102       himin       -> hIceMin
103       himin0      -> hThinIce
104       hihig       -> hThickIce
105       i0          -> i0swFrac
106       transCoef   -> bMeltCoef
107       frac_energy -> fracMelting
108      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
109       with default values (for now) that do not change the results.
110      remove old version of thsice vars advection in pkg/seaice.
111    o in FFIELDS.h:
112      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
113      - make pLoad & sIceLoad always available (but still only used if
114         ATMOSPHERIC_LOADING is #define).
115    o pkg/kpp: replaced _KPP_RL with _RL
116    o bug fixes for vertical diffusivity computations when both KPP and
117        3D diffusivity arrays are used.
118    o pkg/seaice: fix bug in evp solver, while doing that
119      - change (improve?) discretization of stress computations for both
120        cgrid-lsr and evp solver
121      - add a new routine to compute strain rates
122      - the above changes lab_sea results
123      - add no slip conditions for evp solver (off by default), lsr-version
124        may follow
125      - fix exchange for shear at Z-points (does not change lab_sea)
126      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
127        (to force the user to pick a time step since there is not "safe" way
128        of choosing it)
129      - add principal stress diagnostics
130      - rearrange fields for evp a little to avoid having to call a: too many
131        exchanges and b: exchanges for stress trensor components which we do
132        not have.
133      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
134        of evp, complete rewrite for lsr case (latter is does not yet work
135        in all cases)
136    o pkg/kpp: add code to have mixing in shelf ice caverns
137      - add myThid to all kpp routines (long overdue)
138    
139    checkpoint59
140    o pkg/exf:
141      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
142        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
143      - move exf header files from lower_case.h to UPPER_CASE.h ;
144        add missing cvs Header & Name
145      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
146      - add namelist param. selectStressGridPosition, exf_monFreq
147      - retire many _CLIM routines, and remove data.exf_clim
148        + params moved to data.exf
149        + climsst, climsss now handled by exf_set_gen, i.e.
150          climss?period=0 refers to constant field,
151          climss?period=-12 to monthly forcing
152      - split up namelists in data.exf
153    o pkg/seaice:
154      - remove seaice_exch and seaice_exch_uv
155      - remove superfluous exchange of theta
156      - add myThid to seaice_budget_ocean/ice
157      - add new interface for atmospheric wind forcing (C-grid only)
158        + new routine
159        + two new field (taux, tauy for stress over ice)
160        + removed one global field (DAIRN) for C-grid case only
161    o pkg/thsise
162      - 2nd set of modifs for thsice adjoint in conjunction with exf
163    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
164    
165    checkpoint58y_post
166    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
167      vertical diffusivity, similar to that in MOM4; turned on using
168      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
169      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
170    o Added capability for 3D specification of background vertical diffusion
171      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
172      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
173      "data" file that contains the 3D vertical diffusivity coefficients.
174    o ice dynamics (pkg/seaice) with thsice thermodynamics:
175      - add code within pkg thsice to advect & diffuse sea-ice fields
176      similar to (and will replace) what has been added in  seaice_advdiff.F,
177      but: - conserving Mass, Heat & Salt.
178           - better when using non-linear advection scheme (not yet fully tested)
179           - can also be used in atmospheric set-up (for now, only the diffusion).
180    
181    checkpoint58x_post
182    o IO option for global-file compact format:
183      - add options when generating topology (utils/exch2/matlab-topology-generator)
184      - add I/O capability (pkg/mdsio).
185      - adapt utils/matlab/rdmds.m to read this format.
186      for now long-line format not yet supported by pkg/mdsio (& exch2).
187    o shelfice: add a few diagnostics
188    
189    checkpoint58w_post
190    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
191      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
192      (and replace horiVertRatio in NH code).
193      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
194                         and tutorial_plume_on_slope (sensitive to truncation)
195    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
196      directly to drive seaice model (C-grid only)
197    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
198     - reintroduce computation of wind from stress,
199     - compute tau (in exf_bulkformulae.F) from windstress averaged to
200       mass points to avoid tau = 0
201     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
202    o rdmnc.m: make it work with "global" files created with gluemnc
203    o rdmnc.m : some improvements in dealing with singleton dimension
204      (tested on all testreport mnc output files).
205    o genmake2: disable pkg/profiles if netcdf test fails.
206    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
207    o move call to cal_readparms up to make calendar parameters/variable available
208      to all packages
209    
210    checkpoint58v_post
211    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
212      useDynP_inEos_Zc tested.
213    o pkg/exf: changes to properly interpolate/mask/scale initial fields
214    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
215      and portions thereof.  See read_cs.txt for description and examples.
216    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
217      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
218      following the great-circle arc between those 2 points.
219    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
220      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
221    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
222     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
223     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
224     - still needs work (not working with some options ; efficiency to improve)
225       and serious testing.
226     - use this scheme for temperature & salinity in 2 advection test exp.:
227       advect_xy & advect_xz, respectively.
228    
229    checkpoint58u_post
230    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
231    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
232    o testreport: add option "-skipdir" to skip some test.
233    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
234      momentum calculation.
235    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
236    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
237      remove checkpoint.F and the_correction_step.F (no longer used);
238      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
239    o add option (linFSConserveTr) to correct for tracer source/sink due to
240      Linear Free surface
241    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
242    o pkg/thsice: fix reading mnc-pickups
243    
244    checkpoint58t_post
245    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
246    o pkg/mdsio:
247     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
248       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
249       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
250     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
251     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
252       either MDS_READ_FIELD or MDS_WRITE_FIELD )
253     - new S/R (to replace MDSWRITEMETA), which allows to write more
254       informations (variable names, time ...) to meta files.
255     - modify rdmds.m to give back the meta file content.
256    o pkg/diagnostics: change vertical interpolation to be safer, and more
257       flexible (define p-levels to interpolate to in data.diagnostics);
258      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
259       diagnostic pointer.
260    o pkg/seaice: more cleaning up of seaice_growth, added many comments
261    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
262    o fix multi-category seaice:
263     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
264       SEAICE_MULTICATEGORY
265     - fix short wave heat flux
266    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
267       and allow to use EVP solver. Change forward lab_sea: test both EVP
268       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
269    o Initial check-in of lab_sea adjoint
270      (very similar to natl_box_adjoint/code_seaice)
271      * used C-grid and EVP solver
272      * used KPP, GM/Redi
273      * uses inAdExact=.TRUE.
274      * gradient checks fail for both ADM and TLM
275        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
276        f.d. gradients actually seem more problematic than ADM, TLM gradients;
277        issue is related to forward mismatch between g77 an ifort
278    o pkg/seaice: overhaul of thermodynamics
279     - growth.F and groatb.F are replaced by new routine seaice_growth.F
280     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
281     - move a few global fields out of SEAICE.h into seaice_growth.F and
282       make them 2D (FICE/QNETO/ ...)
283     - remove FO (it is the same as QNETO)
284     - introduce a few local fields to avoid modifying external fields such
285       as atemp, etc.
286    
287    checkpoint58s_post
288    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
289      changed exf_set_gen.F so that
290        genperiod=0 means input file is one time-constant field and
291        genperiod=-12 means input file contains 12 monthly means
292    o CG2D: use pre-computed solver main-diagonal (stored in common block);
293      this affects truncation error ; generate new output file for exp. which
294      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
295        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
296        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
297        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
298        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
299        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
300    o start implementation of deep-atmosphere and anelastic formulation
301    o verification: remove 2nd copy of input files and use script "prepare_run"
302      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
303    o mom_common/vecinv/fluxform: fix a few initialisation isssues
304    o profiles: fix for multithreaded case
305    
306    o diagnostics: rename few diags:
307      s/'PRESSURE'/'RCENTER '/g
308      s/'TICE    '/'oceFreez'/g
309      s/'TAUX    '/'oceTAUX '/g
310      s/'TAUY    '/'oceTAUY '/g
311      s/'SWFLUX  '/'oceQsw  '/g
312      s/DIFx/DFxE/g
313      s/DIFy/DFyE/g
314      and add few ocean-forcing diagnostics:
315      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
316    o modifications to pkg/seaice/growth.F and budget.F, which change results of
317      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
318      as actual snow thickness.  It now refers everywhere to effective snow
319      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
320    
321    checkpoint58r_post
322    o modifications to pkg/seaice/growth.F, which change results of
323      lab_sea experiment: fixes pertain to melting snow over open water, to
324      masking EVAP under sea ice, and to using the correct AREA variable for
325      computations of EVAP, PRECIP, HSNOW, and GHEFF
326    o add ability to read bathy, salt, and theta using MNC (off by def)
327    o add flooding algorithm and advection of HSNOW for pkg/seaice;
328      both are turned off by default and do no change any results
329    o seaice advection with pkg/thsice: a step toward the use of non-linear
330      advection scheme, but #ifdef or commented out for now (requires more EXCH).
331    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
332      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
333      in natl_box (affects results @ truncation level: update output.txt)
334    o multi-threading and IO:
335      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
336      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
337        (needed to work with SingleCpuIO): tested in all verif. exp.
338    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
339      affects the results (but none of the verification test uses this scheme).
340    o Adding some pkg/diagnostics capability to pkg/seaice
341      (will certainly be subject to changes)
342    o ctrl: adding new control variables:
343      lwflux, lwdown, evap, snowprecip, apressure, runoff
344    
345    checkpoint58q_post
346    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
347      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
348      high_res_cube configuration by 4% on Columbia.
349    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
350      add (in global_with_exf/code) a version of EXF_INTERP_READ without
351      dynamical allocation (seems to work in multi-threaded).
352    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
353      single CPU io) so that TAF does not have to see EESUPPORT.h
354    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
355    
356    checkpoint58p_post
357    o obcs: stop if obcs is used with useCDscheme = .true.
358    o shelfice:
359     - fix a sign error so that no slip at shelfice interface works
360     - remove stop for combination non-hydrostatic code and shelfice. That does
361       not mean, that the results are correct, but at least they are numerically
362       stable
363    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
364    o added adjoint exch routined for all exch*3d* routines
365      and updated flow directives
366    
367    checkpoint58o_post
368    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
369      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
370    o change controling S/R for writing pickup file (new S/R do_write_pickup)
371      and clean-up reading/writing of pickup files.
372    o fix local version of read/write pickup (NH part) in rotating_tank/code
373    o simplify EXCH interface:
374     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
375     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
376    o added the regrid package
377    o shelfice:
378     - add a simple boundary layer scheme to reduce noise
379     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
380    
381    checkpoint58n_post
382    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
383       local variable (not in common block).
384    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
385      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
386      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
387        to work with SingleCpuIO.
388    o add "_d 0" to real constant of pkg/cfc subroutines ;
389       update exp. cfc_exemple & tutorial_cfc_offline output files.
390    o multi-threading and IO:
391      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
392        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
393      - barrier before and after reading.
394      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
395      - avoid using MDS_WRITELOCAL for LAND pkg output.
396      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
397        common-block variables ; Allows multi-threading with master-thread IO.
398    o change default MAX_NO_THREADS from 32 to 4 ;
399      and stop cleanly when MAX_NO_THREADS is too small.
400    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
401    
402    checkpoint58m_post
403    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
404       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
405    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
406       keep global_ocean.90x40x15 (for AD testing) with former secondary test
407       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
408    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
409        add MITgcm_tutorials (= code + all the tutorials)
410    o ecco, option to compute cost for total ssh (mean+anom)
411    o consistent with addition of ptracer and ssh in pkg/profiles
412    o profiles: adding ptracer and ssh
413    o testreport: change multi-test output-file name
414      (from output.txt.{name} to output.{name}.txt)
415    o profiles: now ok for mutli-tiles case
416    o seaice: add 4 parameters for different advection schemes for area,
417      (effective) seaice thickness, enthalphy, and snow height. Their default
418      is the standard parameter SEAICEadvScheme
419    o calc_gw:
420     - add cosFacU in zonal viscous flux (harmonic.visc.).
421     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
422       of tutorial_plume_on_slope.
423    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
424    o calc_gw: true flux-form, account for horizontal grid spacing.
425      update rotating_tank results, but not plume_on_slope (affected at
426      truncation level, 11 digits).
427    
428    checkpoint58l_post
429    o calc_gw:
430     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
431     - remove side-drag for now (need to fix it); update plume_on_slope results.
432     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
433    o commit code to make SST/SSS weights spatially variable
434      (based on either variable in-situ or variable initial T/S weights)
435    o pkg/ecco:
436      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
437        now based on horizontally varying weights wthetaLev, wsaltLev
438      * cost_averagesflags now returns year indices in addition to day, month
439      * sflux balance is performed on annual basis
440        (sflxumm, sfluxmm2, bal_sfluxmm)
441      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
442        including separate counting and multipliers
443    o pkg/rbcs
444      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
445    
446    checkpoint58k_post
447    o testreport:
448     - always build in dir. "build" (if not there, mkdir build instead of building
449       & running in input)
450     - run in dir run (if it exists), in build otherwise.
451     - call prepare_run (if input/prepare_run exists)
452     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
453    o pkg/exf modifications to interpolation and rotation routines for more
454       reasonable treatment of North Pole singularity: for tracers North Pole
455       value is set to northernmost zonal-mean value, for zonal velocity it is
456       set to zero, and for meridional velocity it is set to northernmost value.
457    o pkg/exf/exf_check_range.F
458     - add tile index to diagnostics and move stop statement to the very
459       end of the routine.
460    o pkg/diagnostics: (diagnostics_main_init.F)
461      define title of isomorphic variables according to the current config.
462    o pkg/thsice with pkg/seaice dynamics:
463    - fix domain of computation (interior only, required for exf) and do exchanges
464    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
465    o towards a standard way of dealing with multi-threading in MONITOR
466      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
467    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
468       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
469    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
470    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
471    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
472       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
473    o tracer advection:
474     - clean-up and simplify calc_common_factors.F
475     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
476       advection subroutine (but still not used within DST advection S/R)
477    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
478    
479    checkpoint58j_post
480    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
481      from file (collects calls previously in FORWARD_STEP)
482    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
483    o adjoint store dir. adjusted accordingly
484    o genmake2
485      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
486    
487    checkpoint58i_post
488    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
489      on wind stress (SEAICEstressFactor defaults to 1.)
490    o Total number of Timers is finite (<=40): comment out 2 non-essential one
491      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
492    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
493      on CS-grid: no longer loosing mass.
494    o exf & curvilinear-grid: no longer modify longitude xC & xG.
495    o pkg/ggl90: fix sloppy output and fix a bug
496    o pkg/seaice: added SEAICEuseEVPpickup parameter
497      - Set to false in order to start EVP solver with
498        non-EVP pickup files when using SEAICEuseEVP
499      - fix sign error in diffusion in seaice_calc_rhs
500    
501    checkpoint58h_post
502    * Modifications for bottom topography control
503      o replace hFacC by _hFacC at various places
504      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
505      o add non-self-adjoint cg2d_nsa
506      o update autodiff support routines
507      o re-initialise hfac after ctrl_depth_ini
508      o works for 5x5 box, doesnt work for global_ocean.90x40x15
509    * Adding verification for 5x5 box (4-layer) bottom topography control
510    
511    checkpoint58g_post
512    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
513       used for mean seasonal cycle, mean diurnal cycle); add an example
514       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
515    o pkg/ggl90:
516      - add parameter (minimum surface kinetic energy)
517      - fix bug (avoiding division by zero)
518    o couple pkg/thsice to pkg/seaice:
519      - modify advection in seaice to accomodate new scalar fields to be advected
520      - only muliDimAdection scheme work with seaice/thsice
521      - mapping of thsice-variables to seaice-variables, back and forth
522      - does not break the verification experiments, but does not give the
523        desired results either
524    o pkg/seaice
525      - make (default) second order advection a bit less confusing?
526    
527    checkpoint58f_post
528    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
529      to pkg/seaice):
530      - new routines thsice_map_exf and thsice_get_exf provide the interface
531      - add an additional formal parameter to thsice_solve4temp
532    o pkg/exf:
533      - add new fields wspeed, snowprecip (to be able to couple to thsice)
534      - correct Stefan-Boltzmann constant
535      - new parameter for longwave surface emittance
536      - separate some stuff from exf_bulkformulae into new routines  
537        exf_radiation, exf_wind
538      - add new parameters and constants: longwave emissivity for ocean, ice
539        and snow, evaporation parameters over ice
540      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
541        either wind from stress or stress from wind
542    o pkg/thSIce:
543    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
544    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
545       and THSICE_CALC_THICKN
546    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
547    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
548      to make debugging easier.
549    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
550    o pkg/bulk_force:
551      - clean-up comments and parameters ;
552      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
553    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
554      generate new output for test-experiment: aim.5l_cs.thSI
555    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
556      testreport accordingly
557    
558    checkpoint58e_post
559    o SEAICE_CGRID adjoint done
560    o R_STAR adjoint implemented.
561      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
562      * need to sort out init. of h0facc, etc.
563    o Make pkg/profile fully independent of ecco,cost, etc. stuff
564      to be able to use it in pure forward.
565    
566    checkpoint58d_post
567    o upgrade simple test-experiment to tutorial example:
568     step.1: duplicate the experiment and (step.2) will remove the old copy.
569      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
570      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
571      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
572      tutorial_global_oce_biogeo    <- copy of dic_example
573      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
574      tutorial_plume_on_slope       <- copy of plume_on_slope
575      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
576      tutorial_global_oce_optim     <- empty for now (David ?)
577      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
578     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
579    o correct a sign problem in cost_scat.F
580    o obcs and ptracers: fix boundary conditions for advections schemes
581      with larger stencil
582    o thsice adjoint: start
583    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
584      completeness
585    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
586      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
587    o ptracers adjoint:
588      * avoid extensive recomputatations
589      * fix missing re-init. of gptr (missed by TAF)
590    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
591      me to turn off the excessive output to STDOUT that this package produces
592    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
593      and add those terms in Vector-Invariant formulation.
594    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
595      if the control period (xx_hfluxperiod etc) is 0
596    o in profiles pkg, clean routines and fix details
597    o in ecco pkg, reading ssh data:
598      fix problem in case the model does not start at iter0=0
599    o fix mnc-pickup/restart for ptracers
600    o new package prifiles:
601      code to compute profile-based cost by Gael Forget
602      (modifs in ecco, ctrl, autodiff)
603    o Benign bug fix in initialization (spotted by M. Mazloff) of
604      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
605    
606    checkpoint58c_post
607    o adjoint: finish NLFS adjoint and provide reference output in
608      verification/global_ocean.90x40x15/results_ad_nlfs
609    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
610      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
611      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
612      with SEAICE_CGRID defined.
613    o move calendarDumps from "data" to "data.cal" and clean-up the code
614      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
615    o add useEXF & useCAL flags (for now, set in hard-coded way)
616    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
617      (were missing in NH mode, and wrong in quasihydrostatic mode).
618      waiting for Chris updated version of calc_gw to add those CALLs.
619    o fix bug in quasihydrostatic S/R ;
620      add a test for this option: global_ocean.90x40x15.qshyd
621    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
622      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
623    o add on/off flag useOffLine for package OFFLINE
624    o seaice:
625      - modify advection so that it works also on the C-grid
626      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
627        problem in multi-tile runs with C-grid
628      - add flags for clipping ice velocities and/or masking solver forcing
629      - fix drag (ocean on ice) formulation and a bug that caused noise in the
630        C-grid solver
631      - added a few comments to seaice_diffusion.F
632      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
633        are now exclusive)
634      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
635        required re-ordering the code a little:
636       + make DAIRN global variable (defined in SEAICE)
637       + move computation of the viscosities eta and zeta into a new separate
638         routine (because I need to recompute them in seaice_ocean_stress.F)
639    
640    checkpoint58b_post
641    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
642      update output.txt of exp. aim.5l_cs.thSI
643    o various mnc cleanups and improvements:
644      + shrink lookup tables by factor of ~4
645      + better error reporting when running out of lookup space
646      + able to handle longer path/file names (up to 500 chars)
647    o adjoint:
648      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
649      - TBD: "hidden" mom_vecinv recomp. in dynamics
650    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
651     (allow to differentiate between forcing components using new integer flags:
652      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
653     and add new flag to put Dissipation tendency out of Adams-Bashforth.
654    o ecco
655      - enable trend removal from SSH anomaly obs.
656    o adjoint
657      - a fix for PmEpR when #undef EXACT_CONSERV
658      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
659      - try to fix "hidden" recomp. in forward_step for NLFS
660        (NLFS seems broken sometimes after I checked it in)
661    o seaice:
662     - add c-grid version of the dynamic solver:
663       + three new routines that are the c-grid substitute lsr, dynsolver
664         and ostres
665       + put a few fields that were local to dynsolver into global common
666         blocks, so that I can move the computation of stresses etc into
667         seaice_lsr (saves coding but may break the adjoint).
668     - replace more hardwired parameters by runtime parameters
669     - add ice masks that mask the rhs of the implicit solvers where there
670       is no ice (commented out in seaice_dynsolver, because i am not sure
671       if this works properly), eventually this should replace the clipping
672       of ice velocities in seaice_dynsolver to +/-40cm/s.
673    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
674      include it only where its needed
675    o move balancing of fluxes before the call of external_forcing_surf
676    o seaice:
677      - correct units of turning angles (now they are really in degrees)
678      - move computation of GWATX/Y out of main routine into dynsolver
679      - initialize GWATX/Y in seaice_init
680    o Apply mask on Fresh-Water flux (needed for SSH forcing).
681      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
682    o seaice: add runtime flags for turning angles (default to zero)
683    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
684      and trend from exf forcing and ctrl control adjustments
685    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
686      (since checkpoint57x_post)
687    o change the default rotation period to 86164.s = the Earth rotation
688    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
689      and based on a reference stratification. Tested within hs94.cs-32x32x5.
690    o seaice advection: add code for choosing between the default (2nd order
691      central differences) and multiDim advection schemes provided by
692      pkg/generic_advdiff
693    o seaice:
694      - removed all references to SEAICE_GRID.h fields from
695        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
696        (cubed-sphere configuration will change a little)
697      - grid computations in seaice_init are obsolete now.
698      - cleaned up code a little so that is easier to read (hopefully).
699      - added new (better?) discretizations of default advection and diffusion
700        (turn on with SEAICEuseFluxForm)
701      - replace 1 in 3d global fields by kSurface in growth.F
702      
703    checkpoint58a_post
704    o seaice:
705      - bug fix in advect.F
706    o shelfice:
707      - separate shelfice load anomaly from pload (breaks with time
708        dependent forcing), => introduce constant field shelficeLoadAnomaly.
709        Its default is 0., but it may be computed more cleverly from (unknown)
710        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
711        done offline. A good approximation of the pressure load anomaly is
712        necessary to avoid large initial adjustment processes underneath
713        deep-reaching shelfice.
714      - small fix in ISOMIP shelfice_thermodynamics
715      - add more sophisticated thermodynamics of Hellmer (1989), this is
716        now the default
717      - give a few constants more intuitive names
718    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
719      if bulk formulae are used in long integration (especially EmPmR). Turn
720      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
721      if balancePrintMean, the imbalance that is substracted is printed to
722      STDOUT.
723    o fix bug (typo) in obcs_apply_eta.F
724    o add a new package shelfice which enables us to model the circulation
725      underneath shelf-ice with draughts of hundreds of meters.
726     - works
727     - to do: + include improved thermodynamics
728              + check whether kSurfC (from model/inc/SURFACE.h) can be used
729                instead of new field kTopC
730              + can we use topoFile, Ro_surf and existing code in ini_depth.F
731                instead of new field R_shelfIce and new code in ini_depth.F
732                and ini_mask_etc.F?
733              + adjust vertical mixing schemes?
734    o seaice pkg:
735     - add a cpp-flag to include a simple formula for a salinity dependent
736       freezing point of sea water at the surface
737     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
738       meridional stresses are now different (and hopefully correct)
739    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
740       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
741       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
742    o pkg/diagnostics: add options and parameters for regional-statistics
743       diagnostics ; define regions by reading a region-mask from a file
744       (might add other options later)
745    o pkg/bulk_force:
746     - add option and parameters to use AIM surface-flux formulae.
747     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
748       others forcing fields (defined in PARM05, parameter file "data") are loaded
749       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
750     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
751     - use the right EXCH call for uwind,vwind (to work on CS-grid).
752     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
753       and parameters (note: calcWindStress replaces .NOT.readwindstress).
754     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
755    
756    checkpoint58
757    o add "--embed-source" option to genmake2 which, when the supporting
758      tools can be compiled (as determined by genmake2) will turn on the
759      embed_files package which then embeds the entire MITgcm source code
760      (*.[fFhc] + Makefile) used for the build within the executable
761      - requested by CNH but off by default
762      - adds a paltry <9MB to the mitgcmuv executable in most cases
763      - only writes the output when useEMBEDSRC in eedata is true
764    o clean up 3-dim. relaxation codes:
765      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
766      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
767      * Thanks to Tom Haine for testing!
768    
769    checkpoint57z_post
770    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
771      affects output (@ truncation level) of exp. plume_on_slope ; updated.
772    o fix the pickup behavior for obcs in combination with ptracers
773    o fix a bug in ptracers_external_fields_load
774    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
775      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
776    o transfered surface NH pressure to eta field (if exactConserv).
777    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
778         and update lab_sea output.txt file.
779    o completing 3-dim. relaxation code: additional term
780         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
781      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
782      * At compile time, in "EXF_OPTIONS.h" set
783          #define  ALLOW_CLIMTEMP_RELAXATION
784          #define  ALLOW_CLIMSALT_RELAXATION
785      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
786          tauThetaClimRelax3Dim = 15552000.0,
787          tauSaltClimRelax3Dim  = 15552000.0,
788      * 3 cases:
789          1) Use a constant-in-time 3-dim. field
790          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
791          3) Real-time relax. to time-evolving prescribed field
792    o Adding Laplacian-type smoothness constraint on
793      initial and boundary (forcing) controls (ic, bc)
794      * enable at compile-time via
795        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
796      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
797      * Absolute scale somewhat unclear so far
798      * no area weighting was included since no other cost term does so far
799    
800    checkpoint57y_post
801    First step for a NLFS adjoint
802    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
803    o new init. routines for calc_r_star, calc_surf_dr
804    o still need to deal with ini_masks_etc
805    o testreport seemed happy
806    checkpoint57y_pre
807    
808    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
809    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
810    o add new offset feature to offline pkg (plus minor cleanup)
811    o cfc fixes for final year of integration
812    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
813      be in GCHEM_OPTIONS).
814    
815    checkpoint57x_post
816    o fix testreport Pb in multiple test experiment.
817    o cleanup our namelist syntax in verification:
818      - make it more F95 standards compliant (some work still needed)
819      - allows the vast majority of our tests to work with gfortran
820    o Non-Hydrostatic:
821     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
822     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
823    o Allow to apply AB on T,S rather than on AB(gT,gS):
824     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
825     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
826       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
827     - need a "clever" read_pickup to restart from the other AB formulation
828    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
829    o remove some unused variables (reduces number of compiler warnings)
830    o adjoint
831      * Disable useVariableViscosity for adjoint for time being
832        (there are a number of extensive recomputations)
833      * Initialize certain variables needed for adjoint
834    
835    checkpoint57w_post
836    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
837                 fix the singleCpuIO RS version of MDSWRITEFIELD
838       and add a WARNING if using globalFiles=T with multi-processors.
839    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
840      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
841    o tracer advection scheme:
842      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
843       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
844       was not very convenient).
845      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
846       (further tests needed for the implicit DST & Flux-Limiter schemes).
847    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
848      and sRef for convenience, handy, when you want to initialize
849      ptracers in a large domain with a constant non-zero value. Also,
850      untangle ptracers_init.F a little.
851    
852    checkpoint57v_post
853    o change dome exp. to use variable viscosity in side-drag terms.
854    o remove all the files from the cfc_offline test since they are now
855      incorporated into tutorial_cfc_offline which has been producing
856      identical results for a few days of testing
857    o add new parameter: sideDragFactor to enable half-slip-side BC
858      and change side-drag S/R to use viscosity from mom_calc_visc
859      (can switch back by setting sideDragFactor=0.); affects results at
860      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
861       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
862    o vorticity & strain are now computed without masking, to account for
863      no-slip-side BC in variable viscosity calculation ; mask is applied
864      anyway later on, before computing advection/coriolis terms.
865    o modify exp4 to test new obcs support for reading from external files
866      and for passive tracers
867    o fix behavior of ptracers_monitor when monitor output is written to a
868      netcdf-file; still not independent of monitor.F (writes in the same
869      file).
870    o change default value of tRef (put a uniform, meaningful value for ocean
871      & atmos) and initialize sRef (was missing, as Martin mentioned).
872    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
873      to be proportional to enstrophy dissipation length.  Thus,
874       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
875      This is now consistent with Smagorinsky and with the manual.
876    
877    checkpoint57u_post
878    o OBCS and PTRACERS: add open boundary support for passive tracers
879      - either use homogenous (pseudo) v.Neumann conditions or prescribe
880        OB-values from file; this is not different from the way theta and salinity
881        are treated
882      - however, Orlanski-radiation conditions are not supported, and the model
883        will stop if you use pTracers and Orlanski at the same time.
884      - beefed up the rountine obcs_external_fields_load: now only those open
885        boundary values are overwritten with values from files for which there
886        are really files, otherwise the OB-fields remain untouched. This makes
887        it possible to use different OBs at different ends of the domain (as
888        with EXF)
889    o reduce number of exch calls in shap_filt (s2).
890    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
891      truncation level) 4/5 MLAdjust test results (11&12 digits match).
892    
893    checkpoint57t_post
894    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
895    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
896      same truncation, independent of the face number: affects affects several
897      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
898    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
899      note that biharmonic viscosity + no-slip was not tested in any experiment.
900    o fix bug in non-linear free-surf side-drag ; generate new output for
901      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
902    o make mnc honor the writeBinaryPrec flag for most kinds of output
903    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
904    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
905      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
906    o add brackets in multi-terms sum to get same truncation, independent of
907      the face number (manage to get exactly same value of gU,gV at the cs-edge)
908      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
909    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
910      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
911      a maximum grid-scale Reynolds number.  Also, changes all length calculations
912      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
913      Suggested values of viscosity parameters found in mom_calc_visc.
914      Many new viscosity diagnostics available.
915    
916    checkpoint57s_post
917    o Add clearing-house for viscosity calculations, mom_calc_visc and
918      correct numerous bugs in LeithD and Smagorinsky discretizations.  
919      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
920      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
921      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
922      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
923      The Strain-Tension form is now called with useStrainTensonVisc=.true.
924      ViscAhStrain and viscAhTension are now retired.
925    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
926    o In response to JMC's bug report, genmake2 now ignores any soft-links
927      that it finds in the *current* directory when searching for files.
928      Soft-links found in any other source directories will still work as
929      they did before.
930    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
931      a C routine to unlimit the stack size
932    o mnc-ify pkg/aim snapshot vars
933    o mnc-ify pkg/land as requested by Daniel
934    o various changes to mnc including:
935      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
936      - output can now be grouped so that all files within a group
937          change the ITER portion of their names in lock-step together
938      - can now read ("global") PER-FACE (in addition to PER-TILE) files
939          and works with both EXCH1 and EXCH2 (but needs more testing)
940      - writing works for all verification test cases w/ g77 on Linux
941    
942    checkpoint57r_post
943    o make MNC variable initialization happen earlier
944    o add diagnostics for (almost) each term of the momentum Eq.
945    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
946    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
947    o remove MINIMAL_TAVE_OUTPUT option ;
948      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
949    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
950      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
951    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
952    o add time-dependent SST, SSS control
953    o cost terms in ecco/ modularized (new cost_generic.F)
954    o cost_averages routines are modularized (new cost_averagesgeneric.F)
955    o new infrastructure for seaice model vs. obs misfits in seaice/
956      * driver from the_main_loop.F is seaice_cost_driver.F
957      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
958      * gradient check in Exp. 6a of natl_box_adjoint/
959    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
960      (see README file)
961    
962    checkpoint57q_post
963    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
964    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
965      - bug was reported by Jean-Michel and Ian Fenty
966    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
967      update exp. cpl_aim+ocn output.
968    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
969      Needed for high-res. runs with large global files
970      to be able to limit tapelev size
971    o Changed some tests for adjoint:
972      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
973      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
974      * global_ocean.90x40x15/ back to default 3-level checkpointing
975    o Modifications to enable scripted COMMON to MODULE conversion
976      * verification/OpenAD/code/ has necessary scripts and description;
977      * converts, compiles and runs successfully;
978    
979    checkpoint57p_post
980    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
981    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
982      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
983    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
984    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
985      (was already the case for dissipation with mom_vecinv,
986       and also the case for grad.PhiHyd when staggered-timeStep)
987      This will allow to put dissipation out-off the AB time-stepping.
988     Unfortunately, affects truncation error. Update output of exp. that "fails"
989      (cg2d matching number) and leave the others for later: front_relax(10),
990      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
991      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
992    
993    checkpoint57o_post
994    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
995      (2) its ready to be documented during the 20050801 DocFest
996    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
997      for ideal_2D_oce and lab_sea on linux_ia32_g77
998    o set to #undef CTRL_SET_OLD_MAXCVARS_30
999      in global1x1_tot/code_seaice_adj to access indices 32, 33
1000      (worth another tag)
1001    
1002    checkpoint57n_post
1003    o adding precip control xx_precip 32
1004    o adding swflux control xx_swflux 33
1005    o Replacing 10 forcing penalty cost routines by 1 generic.
1006    o Implementing partitioning in time-mean and variable adjustment
1007      for atmos. state.
1008    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1009  o in natl_box_adjoint:  o in natl_box_adjoint:
1010    * updated: results_bulk/    * updated exp 1 to 10
1011    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
1012    o updated global1x1/*_seaice_adj/
1013      to incorporate latest changes
1014    o enable useSingleCpuIO for mdsio vector routines
1015      (applies in particular to tapelev I/O)
1016    o removed inefficient K-loop in all active_file*control*.F
1017    
1018  checkpoint57m_post  checkpoint57m_post
1019  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)
