5      ==============================      ==============================
6    
7    o pkg/seaice:
8     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
9     - fix bug in metric terms of u-equation in LSR solver (implicit part),
10       changes verification/lab_sea
11     - rearrange implicit part of u-equation in LSR solver to make it easier to
12       read, understand, and debug. This causes changes at the truncation level.
13     - fix (serious) bug in the boundary conditions (sign error in the implicit
14       part) of the LSR solver. Changes all LSR results.
15     - fixed problem with HSNOW initialization to avoid thick snow when AREA
16       is initilized with small values - does not change lab_sea results.
17     - added HsnowFile initialization capability
18    o pkg/smooth: addition to model/src and pkg/ctrl so allow
19     initialization of pkg/smooth and application to control vector
20    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
21    o dependencies: pkg/profiles requires pkg/cal
22    o pkg/profiles:
23     - added option ALLOW_PROFILES_GENERICGRID
24         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
25         that interpolation information (grid points and coefficients) is provided
26         within the netcdf input files.
27         -> sample matlab scripts can be found in MITgcm_contrib/gael
28         that allow you to prepare netcdf input files.
29     - also modified: cleaner include statements, cleaner error print statements,
30       cleaner stops when error, and more tests of the netcdf input files consistency.
31    
32    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
33    o pkg/seaice:
34     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
35       requires a new routine: seaice_diagnostics_fill.F
36     - make sure that seaice does not move if not forced (pressure replacement
37       method, Hibler and Ip, 1995), changes results
38     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
39     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
40       It is turned off by default (=-1.), because it changes the results.
41     - make it possible to read AREA from a file, too.
42    
43    checkpoint59c
44    o add S/R and diagnostics for oceanic mixed-layer depth
45    o move GMRedi call after all vertical mixing schemes (including KPP)
46    o pkg/thsice:
47     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
48      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
49    o pkg/obcs:
50     - bug fix for balance code
51    o pkg/seaice:
52      - allow values of SEAICE_elasticParm > 1
53      - add new parameter SEAICE_evpTauRelax as an alternative
54        to SEAICE_elasticParm
55      - make lsr boundary conditions free slip (by default), changes result
56      - add code for no slip boundary conditions for lsr
57      - set minimum of zeta to zero (and not 4e8) (changes results)
58      - add a cap on AREA after advecting AREA if seaice_growth is not called
59    o change calculation of Visbeck K:
60      - no longer depend on tapering scheme; instead, compute slope (limited
61        by GM_maxSlope). this is equivalent to what was comuted before with
62        clipping or linear tappering.
63      - fix vertical averaging (wrong by 1/2 level)
64      - leave the old version (but will not be maintained) within
65        #ifdef OLD_VISBECK_CALC / #endif
66      - update output of exp. ideal_2D_oce
67    o change error catch in calc_r_star to improve vectorization
68    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
69      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
70    o adjoint:
71      Re-organized adjoint checkpointing according to Matt Mazloff
72      (but with modifs/completions/cleanups)
73      Storing is now bundled into large arrays to optimized I/O
74      (and second step in cleanup of the_main_loop)
75    
76    checkpoint59b
77    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
78      - export/import (between ocean & coupler) fields needed for ocean DIC.
79    o pkg/seaice:
80      - get rid of three more exchanges seaice_calc_viscosities (required
81        different loop boundaries in seaice_lsr and seaice_ocean_stress)
82      - bug fix in seaice_ocean_stress (update of lab_sea required)
83      - reduce loop boundaries to necessary minimum also in seaice_evp
84      - go back to the old way of computing deltaC/Z as the adjoint likes that
85        better
86    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
87      passive tracer to an Age Tracer) + update output.txt
88    o pkg/exf:
89      - implement A-grid / C-grid selection for wind-stress input files.
90      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
91      for now, in exf_bulk_largeyeager04.F only :
92      - change implementation for case where windspeed + 2. components wind-stress
93        are read-in. AND use rhoConstFresh to convert evap.
94    o pkg/seaice:
95      - use correct EXCH_UV for wind-forcing (on A-grid).
96      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
97        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
98    o pkg/exf:
99      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
100      EXF_INTERPOLATION:
101      - merge global_with_exf/code version of exf_interp_read.F
102        to the main code ;
103      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
104        reading the file ; Important: This options needs to be defined to recover
105        previous code.
106        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
107      - no longer loose real*8 precision along the way when using exf_iprec=64.
108    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
109      - change discretisation of evp-solver in order to avoid another exchange
110        (changes lab_sea) and clean up a little
111      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
112        help the adjoint (this also changes the results slightly)
113      - add a few "_d 0" where they had been missing in seaice_evp.F
114      - cleaning up: remove unused seaice_calc_rhs.F
115    o pkg/exf: some cleaning-up:
116      - change various "constants" into runtime parameters
117      - cleaned-up Large&Yeager04 routine which should eventually
118        replace exf_bulkformulae.F (changed names of S/R and CPP)
119        and merged various ALLOW_ATM_WIND options
120     only used with thsice pkg (in thsice_get_exf.F):
121      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
122        which are used when useStabilityFct_overIce=TRUE (= the default)
123      - change default values of ice & snow emissivity and scale downward LW
124        by ice & snow emissivity.
125    o pkg/thsice:
126     fix few little problems, in thsice_calc_thickn.F:
127      - growth vertically (and not laterally) if iceFrac == iceMaskMax
128      - melt only laterally if hIce < hThinIce (as the comments say)
129      and in thsice_extend.F:
130      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
131      - start to form ice as soon as the minimum ice-volume is reachable.
132     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
133      and cpl_aim+ocn
134    o pkg/kpp
135     - move computation of surface related input fields to KPP into a new
136       subroutine kpp_forcing_surf.F
137     - remove wrong (within bi,bj loops) EXCH calls.
138     - little cleaning (add argument myThid in last position, cvs header ...)
139     - for now, fix conservation problem by exchanging KPPviscAz (may not
140       be the best fix)
141    o pkg/seaice
142     - check for inconsistent evp parameter/cpp-flag combination
143     - remove leftover errIO flat for obsolete name list error handling
144    o OpenAD
145     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
146    
147    checkpoint59a
148    o pkg/seaice: some parameter clarifications and a little bit of clean up
149    o pkg/thsice: rename run-time parameters:
150       himin       -> hIceMin
151       himin0      -> hThinIce
152       hihig       -> hThickIce
153       i0          -> i0swFrac
154       transCoef   -> bMeltCoef
155       frac_energy -> fracMelting
156      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
157       with default values (for now) that do not change the results.
158      remove old version of thsice vars advection in pkg/seaice.
159    o in FFIELDS.h:
160      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
161      - make pLoad & sIceLoad always available (but still only used if
162         ATMOSPHERIC_LOADING is #define).
163    o pkg/kpp: replaced _KPP_RL with _RL
164    o bug fixes for vertical diffusivity computations when both KPP and
165        3D diffusivity arrays are used.
166    o pkg/seaice: fix bug in evp solver, while doing that
167      - change (improve?) discretization of stress computations for both
168        cgrid-lsr and evp solver
169      - add a new routine to compute strain rates
170      - the above changes lab_sea results
171      - add no slip conditions for evp solver (off by default), lsr-version
172        may follow
173      - fix exchange for shear at Z-points (does not change lab_sea)
174      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
175        (to force the user to pick a time step since there is not "safe" way
176        of choosing it)
177      - add principal stress diagnostics
178      - rearrange fields for evp a little to avoid having to call a: too many
179        exchanges and b: exchanges for stress trensor components which we do
180        not have.
181      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
182        of evp, complete rewrite for lsr case (latter is does not yet work
183        in all cases)
184    o pkg/kpp: add code to have mixing in shelf ice caverns
185      - add myThid to all kpp routines (long overdue)
186    
187    checkpoint59
188    o pkg/exf:
189      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
190        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
191      - move exf header files from lower_case.h to UPPER_CASE.h ;
192        add missing cvs Header & Name
193      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
194      - add namelist param. selectStressGridPosition, exf_monFreq
195      - retire many _CLIM routines, and remove data.exf_clim
196        + params moved to data.exf
197        + climsst, climsss now handled by exf_set_gen, i.e.
198          climss?period=0 refers to constant field,
199          climss?period=-12 to monthly forcing
200      - split up namelists in data.exf
201    o pkg/seaice:
202      - remove seaice_exch and seaice_exch_uv
203      - remove superfluous exchange of theta
204      - add myThid to seaice_budget_ocean/ice
205      - add new interface for atmospheric wind forcing (C-grid only)
206        + new routine
207        + two new field (taux, tauy for stress over ice)
208        + removed one global field (DAIRN) for C-grid case only
209    o pkg/thsise
210      - 2nd set of modifs for thsice adjoint in conjunction with exf
211    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
212    
213    checkpoint58y_post
214    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
215      vertical diffusivity, similar to that in MOM4; turned on using
216      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
217      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
218    o Added capability for 3D specification of background vertical diffusion
219      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
220      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
221      "data" file that contains the 3D vertical diffusivity coefficients.
222    o ice dynamics (pkg/seaice) with thsice thermodynamics:
223      - add code within pkg thsice to advect & diffuse sea-ice fields
224      similar to (and will replace) what has been added in  seaice_advdiff.F,
225      but: - conserving Mass, Heat & Salt.
226           - better when using non-linear advection scheme (not yet fully tested)
227           - can also be used in atmospheric set-up (for now, only the diffusion).
228    
229    checkpoint58x_post
230    o IO option for global-file compact format:
231      - add options when generating topology (utils/exch2/matlab-topology-generator)
232      - add I/O capability (pkg/mdsio).
233      - adapt utils/matlab/rdmds.m to read this format.
234      for now long-line format not yet supported by pkg/mdsio (& exch2).
235    o shelfice: add a few diagnostics
236    
237    checkpoint58w_post
238    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
239      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
240      (and replace horiVertRatio in NH code).
241      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
242                         and tutorial_plume_on_slope (sensitive to truncation)
243    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
244      directly to drive seaice model (C-grid only)
245    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
246     - reintroduce computation of wind from stress,
247     - compute tau (in exf_bulkformulae.F) from windstress averaged to
248       mass points to avoid tau = 0
249     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
250    o rdmnc.m: make it work with "global" files created with gluemnc
251    o rdmnc.m : some improvements in dealing with singleton dimension
252      (tested on all testreport mnc output files).
253    o genmake2: disable pkg/profiles if netcdf test fails.
254    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
255    o move call to cal_readparms up to make calendar parameters/variable available
256      to all packages
257    
258    checkpoint58v_post
259    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
260      useDynP_inEos_Zc tested.
261    o pkg/exf: changes to properly interpolate/mask/scale initial fields
262    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
263      and portions thereof.  See read_cs.txt for description and examples.
264    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
265      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
266      following the great-circle arc between those 2 points.
267    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
268      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
269    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
270     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
271     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
272     - still needs work (not working with some options ; efficiency to improve)
273       and serious testing.
274     - use this scheme for temperature & salinity in 2 advection test exp.:
275       advect_xy & advect_xz, respectively.
276    
277    checkpoint58u_post
278    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
279    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
280    o testreport: add option "-skipdir" to skip some test.
281    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
282      momentum calculation.
283    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
284    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
285      remove checkpoint.F and the_correction_step.F (no longer used);
286      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
287    o add option (linFSConserveTr) to correct for tracer source/sink due to
288      Linear Free surface
289    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
290    o pkg/thsice: fix reading mnc-pickups
291    
292    checkpoint58t_post
293    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
294    o pkg/mdsio:
295     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
296       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
297       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
298     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
299     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
300       either MDS_READ_FIELD or MDS_WRITE_FIELD )
301     - new S/R (to replace MDSWRITEMETA), which allows to write more
302       informations (variable names, time ...) to meta files.
303     - modify rdmds.m to give back the meta file content.
304    o pkg/diagnostics: change vertical interpolation to be safer, and more
305       flexible (define p-levels to interpolate to in data.diagnostics);
306      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
307       diagnostic pointer.
308    o pkg/seaice: more cleaning up of seaice_growth, added many comments
309    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
310    o fix multi-category seaice:
311     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
312       SEAICE_MULTICATEGORY
313     - fix short wave heat flux
314    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
315       and allow to use EVP solver. Change forward lab_sea: test both EVP
316       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
317    o Initial check-in of lab_sea adjoint
318      (very similar to natl_box_adjoint/code_seaice)
319      * used C-grid and EVP solver
320      * used KPP, GM/Redi
321      * uses inAdExact=.TRUE.
322      * gradient checks fail for both ADM and TLM
323        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
324        f.d. gradients actually seem more problematic than ADM, TLM gradients;
325        issue is related to forward mismatch between g77 an ifort
326    o pkg/seaice: overhaul of thermodynamics
327     - growth.F and groatb.F are replaced by new routine seaice_growth.F
328     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
329     - move a few global fields out of SEAICE.h into seaice_growth.F and
330       make them 2D (FICE/QNETO/ ...)
331     - remove FO (it is the same as QNETO)
332     - introduce a few local fields to avoid modifying external fields such
333       as atemp, etc.
334    
335    checkpoint58s_post
336    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
337      changed exf_set_gen.F so that
338        genperiod=0 means input file is one time-constant field and
339        genperiod=-12 means input file contains 12 monthly means
340    o CG2D: use pre-computed solver main-diagonal (stored in common block);
341      this affects truncation error ; generate new output file for exp. which
342      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
343        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
344        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
345        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
346        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
347        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
348    o start implementation of deep-atmosphere and anelastic formulation
349    o verification: remove 2nd copy of input files and use script "prepare_run"
350      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
351    o mom_common/vecinv/fluxform: fix a few initialisation isssues
352    o profiles: fix for multithreaded case
353    
354    o diagnostics: rename few diags:
355      s/'PRESSURE'/'RCENTER '/g
356      s/'TICE    '/'oceFreez'/g
357      s/'TAUX    '/'oceTAUX '/g
358      s/'TAUY    '/'oceTAUY '/g
359      s/'SWFLUX  '/'oceQsw  '/g
360      s/DIFx/DFxE/g
361      s/DIFy/DFyE/g
362      and add few ocean-forcing diagnostics:
363      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
364    o modifications to pkg/seaice/growth.F and budget.F, which change results of
365      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
366      as actual snow thickness.  It now refers everywhere to effective snow
367      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
368    
369    checkpoint58r_post
370    o modifications to pkg/seaice/growth.F, which change results of
371      lab_sea experiment: fixes pertain to melting snow over open water, to
372      masking EVAP under sea ice, and to using the correct AREA variable for
373      computations of EVAP, PRECIP, HSNOW, and GHEFF
374    o add ability to read bathy, salt, and theta using MNC (off by def)
375    o add flooding algorithm and advection of HSNOW for pkg/seaice;
376      both are turned off by default and do no change any results
377    o seaice advection with pkg/thsice: a step toward the use of non-linear
378      advection scheme, but #ifdef or commented out for now (requires more EXCH).
379    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
380      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
381      in natl_box (affects results @ truncation level: update output.txt)
382    o multi-threading and IO:
383      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
384      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
385        (needed to work with SingleCpuIO): tested in all verif. exp.
386    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
387      affects the results (but none of the verification test uses this scheme).
388    o Adding some pkg/diagnostics capability to pkg/seaice
389      (will certainly be subject to changes)
390    o ctrl: adding new control variables:
391      lwflux, lwdown, evap, snowprecip, apressure, runoff
392    
393    checkpoint58q_post
394    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
395      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
396      high_res_cube configuration by 4% on Columbia.
397    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
398      add (in global_with_exf/code) a version of EXF_INTERP_READ without
399      dynamical allocation (seems to work in multi-threaded).
400    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
401      single CPU io) so that TAF does not have to see EESUPPORT.h
402    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
403    
404    checkpoint58p_post
405    o obcs: stop if obcs is used with useCDscheme = .true.
406    o shelfice:
407     - fix a sign error so that no slip at shelfice interface works
408     - remove stop for combination non-hydrostatic code and shelfice. That does
409       not mean, that the results are correct, but at least they are numerically
410       stable
411    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
412    o added adjoint exch routined for all exch*3d* routines
413      and updated flow directives
414    
415    checkpoint58o_post
416    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
417      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
418    o change controling S/R for writing pickup file (new S/R do_write_pickup)
419      and clean-up reading/writing of pickup files.
420    o fix local version of read/write pickup (NH part) in rotating_tank/code
421    o simplify EXCH interface:
422     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
423     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
424    o added the regrid package
425    o shelfice:
426     - add a simple boundary layer scheme to reduce noise
427     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
428    
429    checkpoint58n_post
430    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
431       local variable (not in common block).
432    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
433      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
434      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
435        to work with SingleCpuIO.
436    o add "_d 0" to real constant of pkg/cfc subroutines ;
437       update exp. cfc_exemple & tutorial_cfc_offline output files.
438    o multi-threading and IO:
439      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
440        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
441      - barrier before and after reading.
442      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
443      - avoid using MDS_WRITELOCAL for LAND pkg output.
444      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
445        common-block variables ; Allows multi-threading with master-thread IO.
446    o change default MAX_NO_THREADS from 32 to 4 ;
447      and stop cleanly when MAX_NO_THREADS is too small.
448    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
449    
450    checkpoint58m_post
451    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
452       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
453    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
454       keep global_ocean.90x40x15 (for AD testing) with former secondary test
455       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
456    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
457        add MITgcm_tutorials (= code + all the tutorials)
458    o ecco, option to compute cost for total ssh (mean+anom)
459    o consistent with addition of ptracer and ssh in pkg/profiles
460    o profiles: adding ptracer and ssh
461    o testreport: change multi-test output-file name
462      (from output.txt.{name} to output.{name}.txt)
463    o profiles: now ok for mutli-tiles case
464    o seaice: add 4 parameters for different advection schemes for area,
465      (effective) seaice thickness, enthalphy, and snow height. Their default
466      is the standard parameter SEAICEadvScheme
467    o calc_gw:
468     - add cosFacU in zonal viscous flux (harmonic.visc.).
469     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
470       of tutorial_plume_on_slope.
471    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
472    o calc_gw: true flux-form, account for horizontal grid spacing.
473      update rotating_tank results, but not plume_on_slope (affected at
474      truncation level, 11 digits).
475    
476    checkpoint58l_post
477    o calc_gw:
478     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
479     - remove side-drag for now (need to fix it); update plume_on_slope results.
480     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
481    o commit code to make SST/SSS weights spatially variable
482      (based on either variable in-situ or variable initial T/S weights)
483    o pkg/ecco:
484      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
485        now based on horizontally varying weights wthetaLev, wsaltLev
486      * cost_averagesflags now returns year indices in addition to day, month
487      * sflux balance is performed on annual basis
488        (sflxumm, sfluxmm2, bal_sfluxmm)
489      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
490        including separate counting and multipliers
491    o pkg/rbcs
492      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
493    
494    checkpoint58k_post
495    o testreport:
496     - always build in dir. "build" (if not there, mkdir build instead of building
497       & running in input)
498     - run in dir run (if it exists), in build otherwise.
499     - call prepare_run (if input/prepare_run exists)
500     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
501    o pkg/exf modifications to interpolation and rotation routines for more
502       reasonable treatment of North Pole singularity: for tracers North Pole
503       value is set to northernmost zonal-mean value, for zonal velocity it is
504       set to zero, and for meridional velocity it is set to northernmost value.
505    o pkg/exf/exf_check_range.F
506     - add tile index to diagnostics and move stop statement to the very
507       end of the routine.
508    o pkg/diagnostics: (diagnostics_main_init.F)
509      define title of isomorphic variables according to the current config.
510    o pkg/thsice with pkg/seaice dynamics:
511    - fix domain of computation (interior only, required for exf) and do exchanges
512    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
513    o towards a standard way of dealing with multi-threading in MONITOR
514      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
515    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
516       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
517    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
518    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
519    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
520       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
521    o tracer advection:
522     - clean-up and simplify calc_common_factors.F
523     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
524       advection subroutine (but still not used within DST advection S/R)
525    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
526    
527    checkpoint58j_post
528    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
529      from file (collects calls previously in FORWARD_STEP)
530    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
531    o adjoint store dir. adjusted accordingly
532    o genmake2
533      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
534    
535    checkpoint58i_post
536    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
537      on wind stress (SEAICEstressFactor defaults to 1.)
538    o Total number of Timers is finite (<=40): comment out 2 non-essential one
539      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
540    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
541      on CS-grid: no longer loosing mass.
542    o exf & curvilinear-grid: no longer modify longitude xC & xG.
543    o pkg/ggl90: fix sloppy output and fix a bug
544    o pkg/seaice: added SEAICEuseEVPpickup parameter
545      - Set to false in order to start EVP solver with
546        non-EVP pickup files when using SEAICEuseEVP
547      - fix sign error in diffusion in seaice_calc_rhs
548    
549    checkpoint58h_post
550    * Modifications for bottom topography control
551      o replace hFacC by _hFacC at various places
552      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
553      o add non-self-adjoint cg2d_nsa
554      o update autodiff support routines
555      o re-initialise hfac after ctrl_depth_ini
556      o works for 5x5 box, doesnt work for global_ocean.90x40x15
557    * Adding verification for 5x5 box (4-layer) bottom topography control
558    
559    checkpoint58g_post
560    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
561       used for mean seasonal cycle, mean diurnal cycle); add an example
562       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
563    o pkg/ggl90:
564      - add parameter (minimum surface kinetic energy)
565      - fix bug (avoiding division by zero)
566    o couple pkg/thsice to pkg/seaice:
567      - modify advection in seaice to accomodate new scalar fields to be advected
568      - only muliDimAdection scheme work with seaice/thsice
569      - mapping of thsice-variables to seaice-variables, back and forth
570      - does not break the verification experiments, but does not give the
571        desired results either
572    o pkg/seaice
573      - make (default) second order advection a bit less confusing?
574    
575    checkpoint58f_post
576    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
577      to pkg/seaice):
578      - new routines thsice_map_exf and thsice_get_exf provide the interface
579      - add an additional formal parameter to thsice_solve4temp
580    o pkg/exf:
581      - add new fields wspeed, snowprecip (to be able to couple to thsice)
582      - correct Stefan-Boltzmann constant
583      - new parameter for longwave surface emittance
584      - separate some stuff from exf_bulkformulae into new routines  
585        exf_radiation, exf_wind
586      - add new parameters and constants: longwave emissivity for ocean, ice
587        and snow, evaporation parameters over ice
588      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
589        either wind from stress or stress from wind
590    o pkg/thSIce:
591    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
592    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
593       and THSICE_CALC_THICKN
594    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
595    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
596      to make debugging easier.
597    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
598    o pkg/bulk_force:
599      - clean-up comments and parameters ;
600      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
601    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
602      generate new output for test-experiment: aim.5l_cs.thSI
603    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
604      testreport accordingly
605    
606    checkpoint58e_post
607    o SEAICE_CGRID adjoint done
608    o R_STAR adjoint implemented.
609      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
610      * need to sort out init. of h0facc, etc.
611    o Make pkg/profile fully independent of ecco,cost, etc. stuff
612      to be able to use it in pure forward.
613    
614    checkpoint58d_post
615    o upgrade simple test-experiment to tutorial example:
616     step.1: duplicate the experiment and (step.2) will remove the old copy.
617      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
618      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
619      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
620      tutorial_global_oce_biogeo    <- copy of dic_example
621      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
622      tutorial_plume_on_slope       <- copy of plume_on_slope
623      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
624      tutorial_global_oce_optim     <- empty for now (David ?)
625      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
626     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
627    o correct a sign problem in cost_scat.F
628    o obcs and ptracers: fix boundary conditions for advections schemes
629      with larger stencil
630    o thsice adjoint: start
631    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
632      completeness
633    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
634      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
635    o ptracers adjoint:
636      * avoid extensive recomputatations
637      * fix missing re-init. of gptr (missed by TAF)
638    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
639      me to turn off the excessive output to STDOUT that this package produces
640    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
641      and add those terms in Vector-Invariant formulation.
642    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
643      if the control period (xx_hfluxperiod etc) is 0
644    o in profiles pkg, clean routines and fix details
645    o in ecco pkg, reading ssh data:
646      fix problem in case the model does not start at iter0=0
647    o fix mnc-pickup/restart for ptracers
648    o new package prifiles:
649      code to compute profile-based cost by Gael Forget
650      (modifs in ecco, ctrl, autodiff)
651    o Benign bug fix in initialization (spotted by M. Mazloff) of
652      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
653    
654    checkpoint58c_post
655    o adjoint: finish NLFS adjoint and provide reference output in
656      verification/global_ocean.90x40x15/results_ad_nlfs
657    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
658      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
659      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
660      with SEAICE_CGRID defined.
661    o move calendarDumps from "data" to "data.cal" and clean-up the code
662      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
663    o add useEXF & useCAL flags (for now, set in hard-coded way)
664    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
665      (were missing in NH mode, and wrong in quasihydrostatic mode).
666      waiting for Chris updated version of calc_gw to add those CALLs.
667    o fix bug in quasihydrostatic S/R ;
668      add a test for this option: global_ocean.90x40x15.qshyd
669    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
670      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
671    o add on/off flag useOffLine for package OFFLINE
672    o seaice:
673      - modify advection so that it works also on the C-grid
674      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
675        problem in multi-tile runs with C-grid
676      - add flags for clipping ice velocities and/or masking solver forcing
677      - fix drag (ocean on ice) formulation and a bug that caused noise in the
678        C-grid solver
679      - added a few comments to seaice_diffusion.F
680      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
681        are now exclusive)
682      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
683        required re-ordering the code a little:
684       + make DAIRN global variable (defined in SEAICE)
685       + move computation of the viscosities eta and zeta into a new separate
686         routine (because I need to recompute them in seaice_ocean_stress.F)
687    
688    checkpoint58b_post
689    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
690      update output.txt of exp. aim.5l_cs.thSI
691    o various mnc cleanups and improvements:
692      + shrink lookup tables by factor of ~4
693      + better error reporting when running out of lookup space
694      + able to handle longer path/file names (up to 500 chars)
695    o adjoint:
696      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
697      - TBD: "hidden" mom_vecinv recomp. in dynamics
698    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
699     (allow to differentiate between forcing components using new integer flags:
700      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
701     and add new flag to put Dissipation tendency out of Adams-Bashforth.
702    o ecco
703      - enable trend removal from SSH anomaly obs.
704    o adjoint
705      - a fix for PmEpR when #undef EXACT_CONSERV
706      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
707      - try to fix "hidden" recomp. in forward_step for NLFS
708        (NLFS seems broken sometimes after I checked it in)
709    o seaice:
710     - add c-grid version of the dynamic solver:
711       + three new routines that are the c-grid substitute lsr, dynsolver
712         and ostres
713       + put a few fields that were local to dynsolver into global common
714         blocks, so that I can move the computation of stresses etc into
715         seaice_lsr (saves coding but may break the adjoint).
716     - replace more hardwired parameters by runtime parameters
717     - add ice masks that mask the rhs of the implicit solvers where there
718       is no ice (commented out in seaice_dynsolver, because i am not sure
719       if this works properly), eventually this should replace the clipping
720       of ice velocities in seaice_dynsolver to +/-40cm/s.
721    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
722      include it only where its needed
723    o move balancing of fluxes before the call of external_forcing_surf
724    o seaice:
725      - correct units of turning angles (now they are really in degrees)
726      - move computation of GWATX/Y out of main routine into dynsolver
727      - initialize GWATX/Y in seaice_init
728    o Apply mask on Fresh-Water flux (needed for SSH forcing).
729      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
730    o seaice: add runtime flags for turning angles (default to zero)
731    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
732      and trend from exf forcing and ctrl control adjustments
733    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
734      (since checkpoint57x_post)
735    o change the default rotation period to 86164.s = the Earth rotation
736    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
737      and based on a reference stratification. Tested within hs94.cs-32x32x5.
738    o seaice advection: add code for choosing between the default (2nd order
739      central differences) and multiDim advection schemes provided by
740      pkg/generic_advdiff
741    o seaice:
742      - removed all references to SEAICE_GRID.h fields from
743        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
744        (cubed-sphere configuration will change a little)
745      - grid computations in seaice_init are obsolete now.
746      - cleaned up code a little so that is easier to read (hopefully).
747      - added new (better?) discretizations of default advection and diffusion
748        (turn on with SEAICEuseFluxForm)
749      - replace 1 in 3d global fields by kSurface in growth.F
750      
751    checkpoint58a_post
752    o seaice:
753      - bug fix in advect.F
754    o shelfice:
755      - separate shelfice load anomaly from pload (breaks with time
756        dependent forcing), => introduce constant field shelficeLoadAnomaly.
757        Its default is 0., but it may be computed more cleverly from (unknown)
758        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
759        done offline. A good approximation of the pressure load anomaly is
760        necessary to avoid large initial adjustment processes underneath
761        deep-reaching shelfice.
762      - small fix in ISOMIP shelfice_thermodynamics
763      - add more sophisticated thermodynamics of Hellmer (1989), this is
764        now the default
765      - give a few constants more intuitive names
766    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
767      if bulk formulae are used in long integration (especially EmPmR). Turn
768      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
769      if balancePrintMean, the imbalance that is substracted is printed to
770      STDOUT.
771    o fix bug (typo) in obcs_apply_eta.F
772    o add a new package shelfice which enables us to model the circulation
773      underneath shelf-ice with draughts of hundreds of meters.
774     - works
775     - to do: + include improved thermodynamics
776              + check whether kSurfC (from model/inc/SURFACE.h) can be used
777                instead of new field kTopC
778              + can we use topoFile, Ro_surf and existing code in ini_depth.F
779                instead of new field R_shelfIce and new code in ini_depth.F
780                and ini_mask_etc.F?
781              + adjust vertical mixing schemes?
782    o seaice pkg:
783     - add a cpp-flag to include a simple formula for a salinity dependent
784       freezing point of sea water at the surface
785     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
786       meridional stresses are now different (and hopefully correct)
787    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
788       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
789       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
790    o pkg/diagnostics: add options and parameters for regional-statistics
791       diagnostics ; define regions by reading a region-mask from a file
792       (might add other options later)
793    o pkg/bulk_force:
794     - add option and parameters to use AIM surface-flux formulae.
795     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
796       others forcing fields (defined in PARM05, parameter file "data") are loaded
797       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
798     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
799     - use the right EXCH call for uwind,vwind (to work on CS-grid).
800     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
801       and parameters (note: calcWindStress replaces .NOT.readwindstress).
802     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
803    
804    checkpoint58
805    o add "--embed-source" option to genmake2 which, when the supporting
806      tools can be compiled (as determined by genmake2) will turn on the
807      embed_files package which then embeds the entire MITgcm source code
808      (*.[fFhc] + Makefile) used for the build within the executable
809      - requested by CNH but off by default
810      - adds a paltry <9MB to the mitgcmuv executable in most cases
811      - only writes the output when useEMBEDSRC in eedata is true
812    o clean up 3-dim. relaxation codes:
813      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
814      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
815      * Thanks to Tom Haine for testing!
816    
817    checkpoint57z_post
818    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
819      affects output (@ truncation level) of exp. plume_on_slope ; updated.
820    o fix the pickup behavior for obcs in combination with ptracers
821    o fix a bug in ptracers_external_fields_load
822    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
823      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
824    o transfered surface NH pressure to eta field (if exactConserv).
825    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
826         and update lab_sea output.txt file.
827    o completing 3-dim. relaxation code: additional term
828         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
829      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
830      * At compile time, in "EXF_OPTIONS.h" set
831          #define  ALLOW_CLIMTEMP_RELAXATION
832          #define  ALLOW_CLIMSALT_RELAXATION
833      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
834          tauThetaClimRelax3Dim = 15552000.0,
835          tauSaltClimRelax3Dim  = 15552000.0,
836      * 3 cases:
837          1) Use a constant-in-time 3-dim. field
838          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
839          3) Real-time relax. to time-evolving prescribed field
840    o Adding Laplacian-type smoothness constraint on
841      initial and boundary (forcing) controls (ic, bc)
842      * enable at compile-time via
843        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
844      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
845      * Absolute scale somewhat unclear so far
846      * no area weighting was included since no other cost term does so far
847    
848    checkpoint57y_post
849    First step for a NLFS adjoint
850    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
851    o new init. routines for calc_r_star, calc_surf_dr
852    o still need to deal with ini_masks_etc
853    o testreport seemed happy
854    checkpoint57y_pre
855    
856    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
857    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
858    o add new offset feature to offline pkg (plus minor cleanup)
859    o cfc fixes for final year of integration
860    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
861      be in GCHEM_OPTIONS).
862    
863    checkpoint57x_post
864    o fix testreport Pb in multiple test experiment.
865    o cleanup our namelist syntax in verification:
866      - make it more F95 standards compliant (some work still needed)
867      - allows the vast majority of our tests to work with gfortran
868    o Non-Hydrostatic:
869     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
870     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
871    o Allow to apply AB on T,S rather than on AB(gT,gS):
872     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
873     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
874       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
875     - need a "clever" read_pickup to restart from the other AB formulation
876    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
877    o remove some unused variables (reduces number of compiler warnings)
878    o adjoint
879      * Disable useVariableViscosity for adjoint for time being
880        (there are a number of extensive recomputations)
881      * Initialize certain variables needed for adjoint
882    
883    checkpoint57w_post
884    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
885                 fix the singleCpuIO RS version of MDSWRITEFIELD
886       and add a WARNING if using globalFiles=T with multi-processors.
887    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
888      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
889    o tracer advection scheme:
890      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
891       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
892       was not very convenient).
893      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
894       (further tests needed for the implicit DST & Flux-Limiter schemes).
895    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
896      and sRef for convenience, handy, when you want to initialize
897      ptracers in a large domain with a constant non-zero value. Also,
898      untangle ptracers_init.F a little.
899    
900    checkpoint57v_post
901    o change dome exp. to use variable viscosity in side-drag terms.
902    o remove all the files from the cfc_offline test since they are now
903      incorporated into tutorial_cfc_offline which has been producing
904      identical results for a few days of testing
905    o add new parameter: sideDragFactor to enable half-slip-side BC
906      and change side-drag S/R to use viscosity from mom_calc_visc
907      (can switch back by setting sideDragFactor=0.); affects results at
908      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
909       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
910    o vorticity & strain are now computed without masking, to account for
911      no-slip-side BC in variable viscosity calculation ; mask is applied
912      anyway later on, before computing advection/coriolis terms.
913    o modify exp4 to test new obcs support for reading from external files
914      and for passive tracers
915    o fix behavior of ptracers_monitor when monitor output is written to a
916      netcdf-file; still not independent of monitor.F (writes in the same
917      file).
918    o change default value of tRef (put a uniform, meaningful value for ocean
919      & atmos) and initialize sRef (was missing, as Martin mentioned).
920    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
921      to be proportional to enstrophy dissipation length.  Thus,
922       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
923      This is now consistent with Smagorinsky and with the manual.
924    
925    checkpoint57u_post
926    o OBCS and PTRACERS: add open boundary support for passive tracers
927      - either use homogenous (pseudo) v.Neumann conditions or prescribe
928        OB-values from file; this is not different from the way theta and salinity
929        are treated
930      - however, Orlanski-radiation conditions are not supported, and the model
931        will stop if you use pTracers and Orlanski at the same time.
932      - beefed up the rountine obcs_external_fields_load: now only those open
933        boundary values are overwritten with values from files for which there
934        are really files, otherwise the OB-fields remain untouched. This makes
935        it possible to use different OBs at different ends of the domain (as
936        with EXF)
937    o reduce number of exch calls in shap_filt (s2).
938    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
939      truncation level) 4/5 MLAdjust test results (11&12 digits match).
940    
941    checkpoint57t_post
942    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
943    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
944      same truncation, independent of the face number: affects affects several
945      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
946    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
947      note that biharmonic viscosity + no-slip was not tested in any experiment.
948    o fix bug in non-linear free-surf side-drag ; generate new output for
949      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
950    o make mnc honor the writeBinaryPrec flag for most kinds of output
951    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
952    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
953      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
954    o add brackets in multi-terms sum to get same truncation, independent of
955      the face number (manage to get exactly same value of gU,gV at the cs-edge)
956      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
957    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
958      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
959      a maximum grid-scale Reynolds number.  Also, changes all length calculations
960      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
961      Suggested values of viscosity parameters found in mom_calc_visc.
962      Many new viscosity diagnostics available.
963    
964    checkpoint57s_post
965    o Add clearing-house for viscosity calculations, mom_calc_visc and
966      correct numerous bugs in LeithD and Smagorinsky discretizations.  
967      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
968      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
969      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
970      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
971      The Strain-Tension form is now called with useStrainTensonVisc=.true.
972      ViscAhStrain and viscAhTension are now retired.
973    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
974    o In response to JMC's bug report, genmake2 now ignores any soft-links
975      that it finds in the *current* directory when searching for files.
976      Soft-links found in any other source directories will still work as
977      they did before.
978    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
979      a C routine to unlimit the stack size
980    o mnc-ify pkg/aim snapshot vars
981    o mnc-ify pkg/land as requested by Daniel
982    o various changes to mnc including:
983      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
984      - output can now be grouped so that all files within a group
985          change the ITER portion of their names in lock-step together
986      - can now read ("global") PER-FACE (in addition to PER-TILE) files
987          and works with both EXCH1 and EXCH2 (but needs more testing)
988      - writing works for all verification test cases w/ g77 on Linux
989    
990    checkpoint57r_post
991    o make MNC variable initialization happen earlier
992    o add diagnostics for (almost) each term of the momentum Eq.
993    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
994    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
995    o remove MINIMAL_TAVE_OUTPUT option ;
996      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
997    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
998      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
999    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1000    o add time-dependent SST, SSS control
1001    o cost terms in ecco/ modularized (new cost_generic.F)
1002    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1003    o new infrastructure for seaice model vs. obs misfits in seaice/
1004      * driver from the_main_loop.F is seaice_cost_driver.F
1005      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1006      * gradient check in Exp. 6a of natl_box_adjoint/
1007    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1008      (see README file)
1009    
1010    checkpoint57q_post
1011    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1012    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1013      - bug was reported by Jean-Michel and Ian Fenty
1014    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1015      update exp. cpl_aim+ocn output.
1016    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1017      Needed for high-res. runs with large global files
1018      to be able to limit tapelev size
1019    o Changed some tests for adjoint:
1020      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1021      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1022      * global_ocean.90x40x15/ back to default 3-level checkpointing
1023    o Modifications to enable scripted COMMON to MODULE conversion
1024      * verification/OpenAD/code/ has necessary scripts and description;
1025      * converts, compiles and runs successfully;
1026    
1027    checkpoint57p_post
1028    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1029    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1030      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1031    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1032    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1033      (was already the case for dissipation with mom_vecinv,
1034       and also the case for grad.PhiHyd when staggered-timeStep)
1035      This will allow to put dissipation out-off the AB time-stepping.
1036     Unfortunately, affects truncation error. Update output of exp. that "fails"
1037      (cg2d matching number) and leave the others for later: front_relax(10),
1038      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
1039      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
1040    
1041    checkpoint57o_post
1042    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
1043      (2) its ready to be documented during the 20050801 DocFest
1044    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
1045      for ideal_2D_oce and lab_sea on linux_ia32_g77
1046    o set to #undef CTRL_SET_OLD_MAXCVARS_30
1047      in global1x1_tot/code_seaice_adj to access indices 32, 33
1048      (worth another tag)
1049    
1050    checkpoint57n_post
1051    o adding precip control xx_precip 32
1052    o adding swflux control xx_swflux 33
1053    o Replacing 10 forcing penalty cost routines by 1 generic.
1054    o Implementing partitioning in time-mean and variable adjustment
1055      for atmos. state.
1056    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
1057    o in natl_box_adjoint:
1058      * updated exp 1 to 10
1059        (but does not have time-mean vs. variable split results yet)
1060    o updated global1x1/*_seaice_adj/
1061      to incorporate latest changes
1062    o enable useSingleCpuIO for mdsio vector routines
1063      (applies in particular to tapelev I/O)
1064    o removed inefficient K-loop in all active_file*control*.F
1065    
1066    checkpoint57m_post
1067    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
1068      and advect_cs (use EXCH-2 and standard cs-32 grid files).
1069    o pkg/exch2: filling of face-corner halo regions is optional
1070      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
1071    
1072    checkpoint57l_post
1073     tag before updating tutorials (pre-release-2)
1074    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
1075       for output and interpolation of input fields onto model grid)
1076    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
1077       Affects results of exp. rotating_tank ; update output.txt.

1086      new EXF diagnostics output.
1087    
1088    checkpoint57j_post
1089    o exf
1090      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
1091        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
1092        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
1093      * extended diagnostics output
1094        - now includes all EXF variables
1095        - hs, hl moved to common block
1096        - separate S/R for diagnostics, called after ctrl vector is added
1097        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
1098        - EXFqnet contains true Qnet (i.e. includes qsw)
1099      * updated verif. lab_sea, global_with_exf
1100      * Rearranging hflux (exf_mapfields -> exf_getforcing)
1101        to ensure that diagnostics sees a true EXFqnet
1102    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
1103    o diagnostics pkg: change pointers so that 1 diagnostic can be used
1104      several times with different frequencies.
1105    o mnc-ify the thsice package as requested by Daniel Enderton
1106      - the monitor--MNC output needs work
1107      - many attributes need to be added (most are currently blank)
1108    o mnc-ify theaim_v23 package as requested by Daniel Enderton
1109      - many attributes need to be added (most are currently blank)
1110    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)

1115    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
1116     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
1117    
1118    checkpoint57i_post
1119    o Diagnostics package was changed: diagnostic allocation is now deactivated
1120      by setting an empty file name in the namelist (used to be by setting 0 frequency)
1121    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
1122      add 1rst Order upwind vertical Shear.
1123    o add a quick fix for A/B checkpointing in OFFLINE mode
1124    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
1125      end-run around the C/Fortran linking horror in eesup/src/timers.F
1126    o added pkg/runclock: allows user to terminate run based on wall clock
1127    o added non-hydrostatic scaling parameter: nh_am2
1128    o pkg/my82: futile attempt to make results compiler-independent by adding
1129      some "_d 0", etc. no effect.
1130    o for mnc output, fill the 'T' coordinate var with myTime and create a
1131      separate 'iter' variable for iteration count
1132    o pkg/diagnostics:
1133      add new capability: output of Global/Regional & per-level statistics ;
1134      tested against monitor output (including land & thSIce) on various exp.
1135    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
1136    
1137    checkpoint57h_done
1138      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
1139      data.diagnostics, data.gchem, data.ptracers) is done.
1140    
1141    o pkg/diagnostics: prepare for Global/Regional statistics.
1142      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
1143    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
1144      and rename it: DIFFERENT_MULTIPLE
1145    
1146    checkpoint57h_post
1147    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
1148    o pkg/diagnostics: change output frequency, now in seconds (instead
1149      of Nb of iterations). This requires to change data.diagnostics.
1150    checkpoint57h_pre
1151    
1152    o in mnc, let the user create the output dir if both mnc_outdir_date
1153      and mnc_outdir_num are false
1154    o add fflags() to pkg/diagnostics which allows one to specify, on a
1155      per-file basis, the file precision [default behavior is unchanged]
1156    o added diagnostics to pkg/kpp, including computation of mixed layer
1157      depth based on a temperature/density criterion
1158    o updated verification/natl_box to test the new pkg/kpp diagnostics
1159    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
1160    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
1161    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
1162      not mnc -- this mistake was found by JMC and is now corrected
1163    
1164    checkpoint57g_post
1165    o add Adams-Bashforth 3rd Order time stepping:
1166      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
1167      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
1168    checkpoint57g_pre
1169    
1170    o make lambda[Theta,Salt]ClimRelax spatially varying
1171      (default remains spatially uniform constant based on tau)

1189    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
1190      as well as grad(vort3).  Made it compatible with both approximate form
1191      for the cubed sphere and full form of these gradients.  Added flag
1192      useFullLeith to select between approximate and full form.  
1193    o add "d0" in getcon.F to reduce differences between compilers/platforms
